    Cholesteatomas are thought to result from ingrowth of keratinizing squamous epithelium from external ear to middle ear. The cholesteatomas are usually diagnosed by clinical symptoms and signs, otoscopy, and plain radiograms. But various view points are emphasized radiologically before operation, leading to examine by computed tomography (CT), especially in complicated cases. We retrospectively reviewed the CT findings of cholesteatomas in 25 surgically proven cases during the period from May, 1983 to Aug, 1988. The results were as follows: 1. Most cholesteatomas showed soft tissue mass and bony erosion of ossicles (88%), attic wall and mastoid antrum (84%) on temporal bone CT scan. 2. The CT members of cholesteatomas ranged from 25 to 50 HU (avg. 33 HU). 3. Involved sites were attic (16%), antrum (28%), and both attic and antrum (56%). Other sites were middle ear cavity and external auditory canal. 4. Extra-tympanomastoid extension of cholesteatoma was intracranial abscess (8%), exposure of dural sinus (8%), and extension along with neck (4%)

    To determine the diagnostic performance of diffusion-weighted magnetic resonance imaging in the assessment of patients with suspected, but not clinically evident, cholesteatoma. A retrospective analysis of a prospectively collected database of non-echo-planar diffusion-weighted magnetic resonance imaging studies (using a half-Fourier single-shot turbo-spin echo sequence) was conducted. Clinical records were retrospectively reviewed to determine indications for imaging and operative findings. Seventy-eight investigations in 74 patients with suspected cholesteatoma aged 5.7-79.2 years (mean, 41.7 years) were identified. Operative confirmation was available in 44 ears. Diagnostic accuracy of the imaging technique was calculated using operative findings as a 'gold standard'. Sensitivity of the investigation was examined via comparison with clinically evident cholesteatoma. The accuracy of diffusion-weighted magnetic resonance imaging in assessment of suspected cholesteatoma was 63.6 per cent. The imaging technique was significantly less accurate in assessment of suspected cholesteatoma than clinically evident disease (p < 0.001). Computed tomography and diffusion-weighted magnetic resonance imaging may be complementary in assessment of suspected cholesteatoma, but should be used with caution, and clinical judgement is paramount.

    Nine cases of recurrent petrous cholesteatomas have been studied by a 1.5 T MR unit. Gadolinium was injected in 1 case. In all cases, comparison between MR, CT and clinical findings were made. MR allows for accurate topographic study and assessment of cholesteatomas extension, in particular in the posterior fossa and skull base. Relationships with the internal carotid artery and the jugular vein are clearly depicted.

    Abstract Clinically significant sellar cysts unrelated to pituitary adenomas are uncommon. Intracranial cholesteatomas are also rare and are most common in the middle ear and mastoid region. We report an even rarer case of cholesteatoma in the sellar region—a challenging diagnosis guided by clinical presentations, radiological signs, and biopsy, aiming at emphasize the importance of considering cholesteatoma when making differential diagnoses of sellar lesions. We present a case of cholesteatoma in the sellar region in a 56-year-old man with hypopituitarism, diabetes insipidus, and cystic imaging findings. It was difficult to make an accurate diagnosis before surgery. We present detailed analysis of the patient's disease course and review pertinent literature. The patient underwent a surgical exploration and tumor resection through a transsphenoidal approach. Pathologic results revealed a cholesteatoma. The patient's symptoms improved a lot after surgery, and the postoperative period was uneventful. Taken together, the lesion's imaging appearance, pathological characteristics, and clinical features were all unique features that lead to a diagnosis of cholesteatoma. As we did not see such reports by Pubmed and EMBASE, we believe this is the first reported case of sellar cholesteatoma presenting in this manner. This article emphasized that cholesteatomas, although rare, should be considered part of the differential diagnosis of sellar lesions. PMID:26962793

    It was sometimes difficult to differentiate cholesteatoma from accompanied granuloma, cholesterol granuloma, or mastoiditis on high-resolution CT. This study was designed to assess the reliability with which cholesteatoma can be differentiated from those accompanied lesions by gadolinium-enhanced MR imaging. Eight patients suspected to have cholesteatoma were evaluated with GD-DTPA-enhanced MR imaging with a 1.5-T MR imaging GE Signa unit. axial pre- and postcontrast T1-weighted (TR/TE, 600/20) and T2-weighted (TR/TE, 2,000/70) images were studied. MR imaging findings were compared with histologic findings (13 lesions), which included cholesteatoma (n = 6), granuloma (n = 4), cholesterol granuloma (n = 2), and mastoiditis (n = 1). Cholesteatoma had an intermediate to high signal intensity (SI) similar to that of granuloma on both T1- and T2-weighted images. Cholesterol granulomas showed high SI on both T1- and T2-weighted images. Mastoiditis demonstrated marked high SI on T2-weighted images. Cholesterol granuloma and mastoiditis can be distinguished from cholesteatoma or granuloma on both T1- and T2-weighted images. On Gd-DTPA-enhanced images, there was marked enhancement of all granulomas. However, no cholesteatoma enhancement was seen in all six lesions. Gd-DTPA-enhanced images were able to distinguish cholesteatoma from granuloma and to estimate the exact extent of cholesteatoma. Gd-DTPA-enhanced MR imaging is valuable in the evaluation and management of cholesteatoma

    Labyrinthine fistula is one of the most common complications associated with cholesteatoma. It represents an erosive loss of the endochondral bone overlying the labyrinth. Reasons for cholesteatoma-induced labyrinthine fistula are still poorly understood. Evaluate patients with cholesteatoma, in order to identify possible risk factors or clinical findings associated with labyrinthine fistula. Secondary objectives were to determine the prevalence of labyrinthine fistula in the study cohort, to analyze the role of computed tomography and to describe the hearing results after surgery. This retrospective cohort study included patients with an acquired middle ear cholesteatoma in at least one ear with no prior surgery, who underwent audiometry and tomographic examination of the ears or surgery at our institution. Hearing results after surgery were analyzed according to the labyrinthine fistula classification and the employed technique. We analyzed a total of 333 patients, of which 9 (2.7%) had labyrinthine fistula in the lateral semicircular canal. In 8 patients, the fistula was first identified on image studies and confirmed at surgery. In patients with posterior epitympanic and two-route cholesteatomas, the prevalence was 5.0%; and in cases with remaining cholesteatoma growth patterns, the prevalence was 0.6% (p=0.16). In addition, the prevalence ratio for labyrinthine fistula between patients with and without vertigo was 2.1. Of patients without sensorineural hearing loss before surgery, 80.0% remained with the same bone conduction thresholds, whereas 20.0% progressed to profound hearing loss. Of patients with sensorineural hearing loss before surgery, 33.33% remained with the same hearing impairment, whereas 33.33% showed improvement of the bone conduction thresholds' Pure Tone Average. Labyrinthine fistula must be ruled out prior to ear surgery, particularly in cases of posterior epitympanic or two-route cholesteatoma. Computed tomography is a good diagnostic

    Full Text Available A cholesteatoma is a non-neoplastic lesion of the petrous temporal bone commonly described as “skin in the wrong place.” It typically arises within the middle ear cavity, may drain externally via tympanic membrane (mural type, or may originate in the external auditory canal (EAC. The latter type is rarely encountered and typically affects the elderly. EAC cholesteatoma poses diagnostic challenges because it has numerous differential diagnoses. The present case describes a 19-year-old male who presented with gradually progressive diminution of hearing in a previously naïve right ear since 8 months. A soft tissue attenuation lesion confined to the right EAC with erosion of the canal on computed tomography prompted magnetic resonance imaging (MRI. The lesion showed restricted diffusion on MRI. Thus, a diagnosis of spontaneous EAC cholesteatoma was established. The case elucidates the rarity of spontaneous EAC cholesteatoma in a young male. In addition, it describes the role of imaging to detect, delineate the extent, and characterize lesions of petrous temporal bone. The case also discusses common differential diagnoses of EAC cholesteatoma, as well as the importance of diffusion weighted imaging in EAC cholesteatoma similar to its middle ear counterpart.

    The high-resolution computed tomography (CT) appearances of 72 consecutive cases (92 ears) of chronic otomastoiditis were reviewed. The cholesteatomas were verified surgically and/or otologically in 35 of these 92 ears. Discussion was made with special emphasis on the differential diagnosis of cholesteatoma of the middle ear from the non-cholesteatoma otitis media. The CT findings suggestive of cholesteatoma were as follows: the definitive findings was of a soft-tissue opacity filling Purssak's space, with a medial displacement of the malleus and the incus; the possible findings were 1) a bony erosion of the wall of the middle ear cavity, 2) a partial or complete disappearance of the malleus and/or the incus, and 3) an opacification of Purssak's space and the superomedial aspect of the external auditory meatus.

    Fascin is an actin-bundling protein found in cell membrane protrusions and increases cell motility. The expression of fascin in epithelial neoplasms has been described only recently. No data are available concerning the role of this protein in invasive cholesteatoma. Thus, we investigated the expression of fascin in cholesteatoma tissue and the relationship between fascin expression and intraoperative evaluation of the destruction of the ossicular chain and extent of disease. Cholesteatoma specimens of 28 patients and external auditory canal (EAC) skin specimens of the same patients (as the control group) were collected from mastoidectomies. Immunohistochemical technique was used to investigate the fascin expression in all cholesteatoma tissues and EAC skin specimens. Immunohistochemical staining was assessed semiquantitatively based on the thickness of epithelium. SPSS software version 16.0 (SPSS Inc., Chicago, IL, USA) was performed to statistically analyse the relationships between fascin expression and intraoperative evaluation destruction of ossicular chain and extent of the disease. Immunohistochemically, there was no or very low fascin expression observed in normal epithelial cells of EAC skin, while expressed in cholesteatoma tissue. Also, fascin expression in cholesteatoma tissues was significantly correlated with destruction of ossicular chain and extent of the disease. Fascin expression is usually found in cholesteatoma epithelium and is correlated with destruction of the ossicular chain and extent of disease. Considering all of the correlations between the clinical and histopathological findings, 'fascin immunoexpression scoring' may be used for histological grading of cholesteatoma. © 2015 John Wiley & Sons Ltd.

    The high incidence of chronic otitis media with effusion and Eustachian tube dysfunction in children with Down syndrome (DS) may predispose them to cholesteatoma formation. Establishing the diagnosis, choosing the appropriate operative intervention, and post-operative care can be challenging. To describe management strategies for cholesteatoma diagnosis, surgical treatment, and post-operative management in children with Down syndrome. Retrospective case series of 14 patients (17 total ears) with Down syndrome diagnosed with cholesteatoma over a 9-year period. A total of 14 patients with cholesteatoma (3 with bilateral disease) were analyzed. Thirteen ears (76.5%) had ≥2 tympanostomy tubes insertions prior to cholesteatoma diagnosis, and otorrhea and hearing loss were the most common presenting symptoms. Common pre-operative CT scan findings included mastoid sclerosis and ossicular erosion. The average age at first surgery was 9.8 years, and the average follow-up was 4.3 years. For acquired cholesteatoma, most ears were managed with canal wall up (CWU) approaches, but ultimately 6/15 (40.0%) required canal wall down (CWD) approaches. Postoperatively, 3 (20.0%) ears developed new tympanic membrane retraction pockets, but no recurrent cholesteatoma. Four (26.7%) ears developed recurrent disease, and 3 (20.0%) had residual disease at secondary procedures. Ossiculoplasty was performed in 4 ears. Twelve (70.6%) ears were rehabilitated with hearing aids or FM systems. The diagnosis of cholesteatoma in Down syndrome was associated with otorrhea, hearing loss, and CT scan findings of ossicular erosion and mastoid sclerosis. Most cases were managed with CWU surgical approaches. Hearing aid use was common post-operatively. Copyright © 2018 Elsevier B.V. All rights reserved.

    Full Text Available Congenital cholesteatomas are epithelial lesions that present as an epithelial pearl behind an intact eardrum. Congenital and acquired cholesteatomas progress quite differently from each other and progress patterns can provide clues about the unique origin and pathogenesis of the abnormality. However, the exact pathogenic mechanisms by which cholesteatomas develop remain unknown. In this study, key proteins that directly affect cholesteatoma pathogenesis are investigated with proteomics and immunohistochemistry. Congenital cholesteatoma matrices and retroauricular skin were harvested during surgery in 4 patients diagnosed with a congenital cholesteatoma. Tissue was also harvested from the retraction pocket in an additional 2 patients during middle ear surgery. We performed 2-dimensional (2D electrophoresis to detect and analyze spots that are expressed only in congenital cholesteatoma and matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF/MS to separate proteins by molecular weight. Protein expression was confirmed by immunohistochemical staining. The image analysis of 2D electrophoresis showed that 4 congenital cholesteatoma samples had very similar protein expression patterns and that 127 spots were exclusively expressed in congenital cholesteatomas. Of these 127 spots, 10 major spots revealed the presence of titin, forkhead transcription activator homolog (FKH 5-3, plectin 1, keratin 10, and leucine zipper protein 5 by MALDI-TOF/MS analysis. Immunohistochemical staining showed that FKH 5-3 and titin were expressed in congenital cholesteatoma matrices, but not in acquired cholesteatomas. Our study shows that protein expression patterns are completely different in congenital cholesteatomas, acquired cholesteatomas, and skin. Moreover, non-epithelial proteins, including FKH 5-3 and titin, were unexpectedly expressed in congenital cholesteatoma tissue. Our data indicates that congenital cholesteatoma origins

    We have recently proposed a hypothesis that acid leakage through the cholesteatoma epithelium mediates bone resorption in middle ear cholesteatoma. In the present study, we investigated the expressions of transient receptor potential vanilloid (TRPV) channels, which have been shown to play roles in the regulation of epidermal barrier function, in the cholesteatoma epithelium in comparison with the normal skin. Cholesteatoma epithelium and postauricular skin were collected from 17 patients with primary acquired middle ear cholesteatoma who underwent tympanomastoidectomy. Expressions of TRPV1, TRPV3, TRPV4, and TRPV6 were explored by fluorescence immunohistochemistry and quantitative reverse transcription-polymerase chain reaction (qRT-PCR). TRPV1, TRPV3, TRPV4, and TRPV6 mRNAs were all detected by qRT-PCR both in the skin and cholesteatoma tissue. Immunohistochemical staining showed that TRPV1 and TRPV3 were positive in the viable cell layers of the epidermis of the skin, and only TRPV3 was positive in those of the cholesteatoma epithelium. The immunoreactivity for TRPV3 was significantly weaker in cholesteatoma than in the skin. The lower expression of TRPV3 in cholesteatoma may be one of the mechanisms underlying the increased permeability of this tissue. On the other hand, TRPV1, TRPV4, and TRPV6 are unlikely to be involved in the regulation of epithelial permeability in cholesteatoma.

    We developed a new grading system to understand the complicated pathological changes of cholesteatoma in comparison to those of chronic otitis media. This grading system, based on the extent of the cholesteatoma and the surrounding pathlogical changes, is able to simply express the entire pathological condition of the ear with cholesteatoma. Using this grading system, we analyzed the ears of 48 children with cholesteatoma, who underwent tympanoplasty over the past ten years. Their ages ranged from 2 to 15 years with an average age of 8.5 years. The attic and mesotympanic cholesteatomas were associated with greater pathological changes than those observed in postero-superior quadrant cholesteatomas. The degree of the pathological change in the area surrounding the cholesteatoma appears to correlate with the degree of extention of the cholesteatoma. This system is thus considered to be useful for evaluating the improvement in the pathological conditions before and after surgery in patients with cholesteatoma. (author)

    Our results show a significant difference between skin and cholesteatoma biology in vitro. Cholesteatoma disease is a process of destruction characterized by uncontrolled growth of squamous epithelial cells in the middle ear or temporal bone. The pathophysiology behind the cholesteatoma development is controversial, and the mechanisms driving the cholesteatoma growth, migration and destructive properties is still unclear. We aimed to provide a method to study the effect of various compounds on cholesteatoma and skin tissue growth, as well as to further investigate the biological differences between normal skin and cholesteatoma tissue. We have established a method to study cholesteatoma biopsy tissue in vitro. Cholesteatoma tissues from patients undergoing surgery for chronic otitis were grown in culture medium and compared to growth patterns and behaviour of normal retroauricular skin. Conditioned medium was analysed for various secreted cytokines. We found a radial outgrowth of keratinocyte epithelium from the circular biopsies. After 5 days of culture we found a significant growth of both cholesteatoma and skin-derived cells. Cholesteatoma samples showed higher growth rate as compared with skin control cultures from the same patient. Moreover, the cholesteatoma cells showed higher production of monocyte chemoattractant protein-1 (MCP-1) and interleukin (IL)-6 as compared with normal skin.

    Operative findings of the supratubal recess were examined in the 30 patients with acquired cholesteatoma. They were compared with findings of high-resolution CTs (HRCTs) obtained preoperatively. Thus the role of HRCT in cholesteatoma involving the supratubal recess were evaluated. HRCTs of 172 ears without otitis media and 65 ears with tubotympanic type otitis media were analyzed as control. The HRCT has proved to provide excellent informations regarding the presence of cholesteatoma in the supratubal recess. Diagnostic points were as follows. (1) Destruction of the ''cog''. (2) Erosion or destruction of surrounding bony structures, for example, facial canal, tympanic tegmen. (3) Soft tissue density in the supratubal recess. (author)

    To evaluate the value of HRCT imaging in middle ear cholesteatoma, we prospectively analysed the CT images in 28 surgically proven cases with cholesteatomas regarding main site of lesion, ossicular change, facial nerve exposure and fistula formation. The most common main site of lesion was the epitympanum (92.8%). The results of sensitivity, positive predictability, and accuracy by CT imagings were as follows: for ossicular involvement, 94.1%, 88.8%, and 86.2% in malleus, 96.0%, 88.8%, and 85.7% in incus, 81.2%, 81.2%, and 78.5% in stapes; for facial nerve exposure, 66.6%, 57.1%, and 81.2%: for fistula formation, 100%, 75.0%, and 96.4%, respectively. In conclusion, the temoral bone HRCT imaging is an accurate preoperative method in detecting main lesion site, ossicular involvement, fistula formation. Because of the low sensitivity and positive predictability in detecting facial nerve exposure, it is necessary to correlate the HRCT images with the clinical status.

    Seventy-three cases of adult cholesteatoma, including 52 cases of pars flaccida type cholesteatoma and 21 of pars tensa type cholesteatoma, were examined using high resolution computed tomography, in both axial (lateral semicircular canal plane) and coronal sections (cochlear, vestibular and antral plane). These cases were classified into two subtypes according to the presence of extension of cholesteatoma into the antrum. Sixty cases of chronic otitis media with central perforation (COM) were also examined as controls. Various locations of the middle ear cavity were measured in terms of size in comparison with pars flaccida type cholesteatoma, pars tensa type cholesteatoma and COM. The width of the attic was significantly larger in both pars flaccida type and pars tensa type cholesteatoma than in COM. With pars flaccida type cholesteatoma there was a significantly larger distance between the malleus and lateral wall of the attic than with COM. In contrast, the distance between the malleus and medial wall of the attic was significantly larger with pars tensa type cholesteatoma than with COM. With cholesteatoma extending into the antrum, regardless of the type of cholesteatoma, there were significantly larger distances than with COM at the following sites: the width and height of the aditus ad antrum, and the width, height and anterior-posterior diameter of the antrum. However, these distances were not significantly different between cholesteatoma without extension into the antrum and COM. The hitherto demonstrated qualitative impressions of bone destruction in cholesteatoma were quantitatively verified in detail using high resolution computed tomography. (author)

    Three normal volunteers and 57 patients with cholesteatoma were examined by high resolution computed tomography. Serial sections were made through the temporal bone at the nasaly inclined position of 30 degree to the orbitomeatal line (semiaxial plane ; SAP). The findings of temporal bone structures in normal subjects were evaluated in SAP and axial plane (OM). Although the both planes showed good visualization, SAP showed both the eustachian tube and tympanic cavity in one slice. In cholesteatoma soft tissue masses in the tympanic cavity, mastoid air cells and Eustachian tube were demonstrated clearly by SAP. (author)

    The role of high-resolution computed tomography (HRCT) and magnetic resonance imaging (MRI) in the diagnosis of preoperative and postoperative complications caused by acquired cholesteatomas will be described in this paper. The pre- and postoperative imaging of the temporal bone was performed with HRCT and MRI. HRCT and MRI were performed in the axial and coronal plane. MRI was done with T2 weighted and T1 weighted sequences both before and after the intravenous application of contrast material. All imaging findings were confirmed clinically or surgically. The preoperative cholesteatoma-caused complications depicted by HRCT included bony erosions of the ossicles, scutum, facial canal in the middle ear, tympanic walls including the tegmen tympani, and of the labyrinth. The preoperative cholesteatoma-caused complications depicted by MRI included signs indicative for labyrinthitis, and brain abscess. Postoperative HRCT depicted bony erosions caused by recurrent cholesteatoma, bony defects of the facial nerve and of the labyrinth, and a defect of the tegmen tympani with a soft tissue mass in the middle ear. Postoperative MRI delineated neuritis of the facial nerve, labyrinthitis, and a meningo-encephalocele protruding into the middle ear. HRCT and MRI are excellent imaging tools to depict either bony or soft tissue complications or both if caused by acquired cholesteatomas. According to our findings and to the literature HRCT and MRI are complementary imaging methods to depict pre- or postoperative complications of acquired cholesteatomas if these are suspected by clinical examination.

    A study was conducted to determine the reliability of mastoid X-rays in the preoperative assessment of cholesteatoma. A total of 30 patients (15 males and 15 females) who underwent mastoid surgery at the Makati Medical Center from March 1989 to March 1992 were included in the study. Results suggest that the absence of cholesteatoma of mastoid X-rays correlates poorly with actual intraoperative findings. (author). 2 refs.; 2 tabs

    Keratosis obturans (KO) and external auditory canal cholesteatoma (EACC) have been considered separate entities. While the disorders are distinct, they share many overlapping characteristics, making a correct diagnosis difficult. In the present study, we compared their clinical characteristics and radiological features to clarify the diagnostic criteria. Retrospective case series. Academic medical center. The clinical data of 23 cases of EACC and KO were retrospectively reviewed. The following clinical characteristics were compared between the 2 groups: sex, age, onset of symptoms, follow-up period, audiometric results, and imaging findings on temporal bone computed tomography including bilaterality, location, and the presence of extension to adjacent tissue. The mean age of the EACC group was significantly older than that of the KO group. All of the cases of EACC occurred unilaterally, and bilateral occurrences of KO were observed in 4 of 9 cases. All of the lesions in the KO group were circumferential, and no lesion in the EACC group invaded the superior canal wall. No significant differences in symptoms, such as acute otalgia, otorrhea, and hearing loss, were noted between the 2 groups. The incidence of conductive hearing impairment more than 10 dB was higher in the KO group than in the EACC group. Thus, KO and EACC are 2 distinct disease entities that share common features in clinical characteristics except for predominant age and bilaterality. Conservative treatment with meticulous cleaning of the lesion was successful in most cases with a long-term follow-up. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2014.

    To introduce a simple and alternative surgical technique, minimally invasive transcanal myringotomy (MITM), for early stage congenital cholesteatoma in children and to evaluate the feasibility and results of MITM for management of early stage congenital cholesteatoma with respect to its effectiveness and safety. Retrospective review. Between August 2008 and September 2012, a total of 36 patients with congenital cholesteatoma met the inclusion criteria and were analyzed. Patient medical records, including demographic characteristics, intraoperative findings, and follow-up records, were reviewed. Subjects consisted of 23 males (64%) and 13 females (36%), and the age at operation ranged from 12 months to 6 years (mean age = 3 years and 6 months). The number of congenital cholesteatoma was as follows: 26 patients at stage I and 10 patients at stage II. The follow-up duration was between 12 and 56 months, with an average of 30 months. There were no postoperative complications such as tympanic membrane perforation, dizziness, or secondary middle ear infection. Among 36 patients who had undergone the MITM approach for the treatment of congenital cholesteatoma, five (13.8%) showed recurrence and underwent a second-look operation. On the basis of our data, the MITM approach is a useful surgical technique for early stage congenital cholesteatoma in children. It has many advantages, in that there is no external wound and it is a simple surgical technique that involves easy postoperative care, a short operation time and hospitalization period, avoidance of serious complications, and easy repeatability for recurrence. © 2013 The American Laryngological, Rhinological and Otological Society, Inc.

    HYPOTHESIS: The goal of this work is to characterize the morphology and lipid composition of acquired cholesteatoma. We hypothesize that constitutive lipid membranes are present in the cholesteatoma and resemble those found in human skin stratum corneum. METHODS: We performed a comparative...... noninvasive structural and lipid compositional study of acquired cholesteatoma and control human skin using multiphoton excitation fluorescence microscopy-related techniques and high-performance thin-layer chromatography. RESULTS: The structural arrangement of the cholesteatoma is morphologically invariant...... along a depth of more than 200 μm and resembles the stratum corneum of hyperorthokeratotic skin. Lipid compositional analyses of the cholesteatoma show the presence of all major lipid classes found in normal skin stratum corneum (ceramides, long chain fatty acids, and cholesterol). Consistent with this...

    : The results show that the total lipid content of the cholesteatoma matrix is similar to that of stratum corneum from skin and that the cholesteatoma matrix unquestionably contains cholesterol. The cholesterol content in the cholesteatoma matrix is increased by over 30% (w/w dry weight) compared to the control....... The cholesterol sulfate content is below 1% of the total lipids in both the cholesteatoma and the control. Cholesterol ester was reduced by over 30% when compared to the control. CONCLUSIONS: The content of cholesterol in the cholesteatoma matrix is significantly different from that in stratum corneum from skin...

    The distribution of free calcium ions in normal skin and cholesteatoma epithelium was investigated using the oxalate precipitation method. In agreement with previous observations, we could demonstrate a calcium ion gradient in normal epidermis where the cells in stratum basale and spinosum reside...... appeared where oblong accumulations of free calcium ions were found basally in the stratum. These findings provide evidence that fluctuations in epidermal calcium in cholesteatoma epithelium may underlie the abnormal desquamation, may contribute to the formation of an abnormal permeability barrier and may...

  8. Cholesteatoma behind an intact tympanic membrane: histopathologic evidence for a tympanic membrane origin.

    Sudhoff, H; Linthicum, F H

    2001-07-01

    Several theories have been proposed with respect to the origin and pathogenesis of cholesteatoma behind an intact tympanic membrane. The authors describe a case of cholesteatoma behind an intact tympanic membrane in a 71-year-old man with a history of tympanic membrane retraction fixed to the incus without evidence of a perforation. The membrane eventually became detached, and remnants of keratinizing squamous epithelium were found on the incus. Mechanisms such as metaplasia, ectopic epidermis rests, or ingrowth of meatal epidermis have been proposed to explain the pathogenesis of cholesteatoma behind an intact tympanic membrane. These findings, based on temporal bone histopathology, support the role of an acquired epidermal rest. This case report provides evidence that cholesteatoma behind an intact tympanic membrane can be established from a resolved retraction of the pars tensa of the tympanic membrane.

    Full Text Available ntroduction: Chronic otitis media (COM is regarded as one of the disabling diseases which have a great influence on the quality of life. Because of the surgical approach of cholesteatoma, timely diagnosis is very important in management of patients with COM. The purpose of this study was to assess the frequency of cholesteatoma in patients with COM, demographic factors and disease related factors. Materials and Methods: In this retrospective study, medical records of 100 patients with COM who had surgery since 2005 to 2009 in Imam Reza Hospital were selected. Patients’ age, gender, duration of COM, clinical manifestations, location of perforation of tympanic membrane and presence or absence of cholesteatoma were analyzed by SPSS statistical software and some tables and graphs were planned. Results: patients   included 70 males and 30 females with an average age of 23.08 ± 11.35. Mean of COM duration was 8.04 ± 7.14 years. The most common manifestations of the disease were otorrhea (92% and hearing loss (80%. The most frequent type of tympanic perforation was total perforation. Frequency of cholesteatoma was 42% and it was more common in males than females (42.9% and 40%. Presence of choleasteatoma was related to gender, age, location of tympanic perforation, presence of otorrhea and hearing loss. Conclusion: Prevalence of cholesteatoma in patients  with COM  in  Mashhad  is more than  other  cites of Iran and  also other  countries, but it is less than prevalence of non cholesteatomatos COM. It is very important to pay more attention to patients with COM who are evaluated about presence of cholesteatoma, specially those with otorrhea, hearing loss, total perforation of tympanic membrane or male gender.

    Compared to the normal epidermal epithelium, cholesteatomas have altered growth properties characterized by the excessive growth of keratinocytes leading to mucosal destruction. Either congenital or acquired, these lesions, which grow in the middle ear space, the petrous apex or the mastoid of temporal bones, are mostly considered benign skin tumoral lesions. However, many questions remain concerning their pathophysiology. Numerous studies have been proposed to identify those cholesteatoma lesions at risk of recurrence, a possible event that may cause hearing loss. We examined patients with petrous apex or mastoid cholesteatoma in order to analyze the expression of various neurotransmitters, neurotrophins and their receptors and the Ki-67 antigen for identification of a possible relationship between clinical outcome and histopathological behaviour in terms of the proliferative activity of cholesteatomas. Expression of the analyzed molecules was studied using immunohistochemical methods in seven adult patients with petrous apex cholesteatoma who underwent surgical removal of the lesion. Our results, in accordance with published data, confirm that Molecular Immunology Borstel-1 (MIB-1) and certain neurotransmitters could be useful in the prognostic evaluation of the risk of recurrence of aggressive forms of cholesteatoma.

    Introduction: Cholesteatoma is a progressively growing process that destroy the neighboring bony structures and treatment is surgical removal. Follow-up is important in the postoperative period, since further surgery is necessary if recurrence is present, but not if granulation tissue is detected. This study evaluates if diffusion-weighted MR imaging alone can be a reliable alternative to CT, without use of contrast agent for follow-up of postoperative patients in detecting recurrent cholesteatoma. Materials and methods: 26 consecutive patients with mastoidectomy reporting for routine follow-up CT after mastoidectomy were included in the study, if there was loss of middle ear aeration on CT examination. MR images were evaluated for loss of aeration and signal intensity changes on diffusion-weighted sequences. Surgical results were compared with imaging findings. Results: Interpretation of MR images were parallel with the loss of aeration detected on CT for all 26 patients. Of the 26 patients examined, 14 were not evaluated as recurrent cholesteatoma and verified with surgery (NPV: 100%). Twelve patients were diagnosed as recurrent cholesteatoma and 11 were surgically diagnosed as recurrent cholesteatoma (PPV: 91.7%). Four of these 11 patients had loss of aeration size greater than the high signal intensity area on DWI, which were surgically confirmed as granulation tissue or fibrosis accompanying recurrent cholesteatoma. Conclusion: Diffusion-weighted MR for suspected recurrent cholesteatoma is a valuable tool to cut costs and prevent unnecessary second-look surgeries. It has the potential to become the MR sequence of choice to differentiate recurrent cholesteatoma from other causes of loss of aeration in patients with mastoidectomy.

    Non-EPI DW imaging is increasingly being used as a sensitive sequence in detecting cholesteatomas especially if CT findings are not confirmatory. Cholesteatoma appears as a hyperintense focus on DWI. We present two cases of mucous retention cysts in the mastoid temporal bone/middle ear cavity, which present as hyperintense on non-EPI DWI and potentially may mimic cholesteatomas. Differentiating between the two conditions is important, as surgery can be avoided in mucous retention cysts. We have also discussed ways to differentiate between these two conditions on MRI.

    In order to determine specific differences, we compared the temporal bone CT findings of chronic otitis media (COM) with and without cholesteatoma, focusing on bone change. Between 1997 and 1998, 82 patients (84 cases) underwent temporal bone CT and were shown to have COM, with or without cholesteatoma after mastoidectomy and tympanoplasty. There were 36 cases of COM with cholesteatoma (26 patients, M:F =3D 11:15; age range, 16-61 (mean, 36,2) years), and 58 cases without chlesteatoma (56 patients, M:F =3D 25:31, age range, 15-61 (mean, 36.2) years). The findings of temporal bone CT were analysed at the point of bony changes including erosion and medial displacement of ossicles (malleus, incus, and stapes), erosion or destruction of the scutum, tegmen, facial canal, and lateral semicircular canal, and ballooning of the tympanic cavity and mastoid antrum. In addition, the soft tissue changes seen on temporal bone CT were analyzed at the site of lateral bulging of soft tissue in Prussak's space, perforation of the pars flaccida, tympanic membrane retraction, and tympanosclerosis. We retrospectively compared the findings of temporal bone CT with the surgical findings, and to assess statistical significance, the Chi-square test was used. Bone erosion or destruction was seen in 36.2% of COM cases without cholesteatoma, and in 96.2% of cases with cholesteatoma. Comparing COM with and without cholesteatoma, the erosion of ossicles including the malleus (81%, 24%), incus (88%, 14%), stapes (58%, 10%), scutum (88%, 10%), facial canal (8%, 0%), and lateral semicircular canal (8%, 0%), was more common in COM with cholesteatoma (p-value less than 0.05), with the exception of erosion of the tegmen (8%, 3%). Other bony changes including medial displacement of ossicles (27%, 3%), ballooning of tympanic cavity and mastoid antrum (96%, 16%), and the soft tissue changes including lateral bulging of soft tissue in Prussak's space (58%, 14%) and perforation of the pars flaccida (35

    Full Text Available Cholesteatomas are very rare benign, progressive lesions that have embryologic derivation and usually result in progressive exfoliation and confinement of squamous epithelium behind an intact or preciously infected tympanic membrane. To the best of our understanding no reports demonstrates the extension of cholesteatoma from the temporal bone into the foramen magnum. We therefore present a case of cholesteatoma extending down into the foramen magnum. We report a case of 67- year-old man with a giant cholesteatoma extending into the foramen magnum without substantial destruction of the mastoid and petrous temporal bones. The patient’s major symptoms were recurrent tinnitus in the left ear and dizziness with unilateral conductive hearing loss. A working diagnosis of cholesteatomas was made combining the symptoms and magnetic resonance imaging findings. He was then successfully operated on with very minimal postoperative complications. Cholesteatomas originating from the mastoid bone often linger with the patients for many years in a subclinical state and progress into a massive size before causing symptoms. Patients with unilateral conductive hearing loss who are otherwise asymptomatic and have a normal tympanic membrane should be suspected with a progressive cholesteatoma. Cholesteatoma should be one of the working diagnosis when an elderly patient present with unilateral conductive hearing loss that is associated with tinnitus and dizziness.

    HIV-positive children are possibly more prone to developing cholesteatoma. Chronic inflammation of the middle ear cleft may be more common in patients with HIV and this may predispose HIV-positive children to developing cholesteatoma. There are no studies that describe the radiological morphology of the middle ear cleft in HIV-positive compared to HIV-negative children with cholesteatoma. Compare the radiological differences of the middle ear cleft in HIV-positive and HIV-negative children with cholesteatoma. A retrospective, cross-sectional, observational analytical review of patients with cholesteatoma at our institute over a 6 year period. Forty patients were included in the study, 11 of whom had bilateral cholesteatoma and therefore 51 ears were eligible for our evaluation. HIV-positive patients had smaller (p=0.02) mastoid air cell systems (MACS). Forty percent of HIV-positive patients had sclerotic mastoids, whereas the rate was 3% in HIV-negative ears (p<0.02). Eighty-two percent of the HIV-positive patients had bilateral cholesteatoma compared to 7% of the control group (p<0.02). There was no difference between the 2 groups with regards to opacification of the middle ear cleft, bony erosion of middle ear structures, Eustachian tube obstruction or soft tissue occlusion of the post-nasal space. HIV-positive paediatric patients with cholesteatoma are more likely to have smaller, sclerotic mastoids compared to HIV-negative patients. They are significantly more likely to have bilateral cholesteatoma. This may have implications in terms of surveillance of HIV-positive children, as well as, an approach to management, recurrence and follow-up. HIV infection should be flagged as a risk factor for developing cholesteatoma. Copyright © 2018. Published by Elsevier B.V.

    Full Text Available Background/Aim. The mastoid is the rarest site for the onset of congenital cholesteatoma (CC. The symptoms are atypical and minimal. The aim of this multicenter retrospective descriptive study was to define this extremely rare condition and its clinical presentation, diagnosis and management. Methods. We analyzed data files for a 15- year period in 4 tertiary otology centers and discovered 6 patients with the diagnosis of CC of the mastoid. Results. The clinical presentation of CC varied from incidental findings in patient to patient with otogenic meningitis. The most common findings during surgical procedures were mastoid cortex erosion, sigmoid plate dehiscence, dural exposure and external canal wall destruction. Conclusion. CC of mastoid origin tends to occur in adult patients probably because of minimal symptoms and the delayed diagnosis. It can exist for years in a nonaggressive state and develop to giant sizes. In children it is almost incidentally diagnosed. Early imaging is necessary in order to prevent serious complication.

    The growth of a middle ear cholesteatoma behind a normal tympanic membrane is a rate though possible event. In such cases, CT may provide useful information for diagnosis. The results are presented of a CT study carried out on 14 patients affected with unilateral conductive hearing loss and with normal tympanic membrane. CT allowed the diagnosis of meddle ear cholesteatoma to be made in all cases. All patients were treated with surgery: 8 of them underwent tympanoplasty and 6 explorative tympanotomy. While the diagnosis of cholesteatoma was confirmed in 13 patients, in 1 case tympanosclerosis was diagnosed. CT diagnosis of middle ear cholesteatoma is based on the demonstration of a low-density soft-tissue mass, in association with bone erosion or ossicular dislocation. The author emphasizes the difficulty of a CT diagnosis of cholesteatoma in the patients with middle ear soft-tissue masses in the absence of bone alterations

    blood supply or production of neurotoxic substances secreted from either the cholesteatoma matrix or bacteria enclosed in the tumor. AIM: To evaluate the incidence, clinical features and treatment of the facial palsy due cholesteatoma. STUDY DESIGN: Clinical retrospective. MATERIAL AND METHOD: Retrospective study of 10 cases of facial paralysis due cholesteatoma selected through a survey of 206 decompressions of the facial nerve due various aetiologies realized in the last 10 years in UNIFESP-EPM. RESULTS: The incidence of facial paralysis due cholesteatoma in this study was 4,85%, with female predominance (60%. The average age of the patients was 39 years. The duration and severity of the facial palsy associated with the extension of lesion were important for the functional recovery of the facial nerve. CONCLUSION: Early surgical approach is necessary in these cases to improve the nerve function more adequately. When disruption or intense fibrous replacement occurs in the facial nerve, nerve grafting (greater auricular/sural nerves and/or hypoglossal facial anastomosis may be suggested.

    Three cases of cholesteatoma-like disease in the ear canals after radiation therapy for head and neck tumor were reported. Effect of irradiation on bone and soft tissue including skin brings about pathological reaction to the external ear canal as well. Two types of disease resembling cholesteatomas have been recognized: keratosis obturans (KO) and external auditory canal cholesteatoma (EACC). KO appears to be derived from disease of canal skin involved with keratinization, creating a widning of the canal. EACC, on the other hand, seems to develop in the disease of bony canal where a localized absorption of its bone with invasion of squamous epithelium takes place. (author)

    To report two cases of an undescribed association of first branchial cleft fistula and middle ear congenital cholesteatoma and to discuss management and embryological hypothesis. Retrospective study and review of the literature Both patients were young girls free of past medical or surgical history. Surgical removal of the first cleft anomaly found in the two cases a fistula routing underneath the facial nerve. Both cholesteatomas were located in the hypotympanum, mesotympanum. In one case, an anatomical link between the two malformations was clearly identified with CT scan. The main embryological theories and classification are reviewed. A connection between Aimi's and Michaels' theories (congenital cholesteatoma) and Work classification might explain the reported clinical association.

    Recurrent cholesteatoma after surgical excision occurs frequently in children. Until recently, a surgical second look was mandatory and considered as standard reference. MRI including a delayed T1 sequence after gadolinium injection and diffusion-weighted imaging (DWI) has proved its efficiency but has been evaluated mainly in adults. Our purpose was to evaluate the accuracy of DWI to diagnose recurrence of cholesteatoma in children. We evaluated prospectively with MRI 20 ears in 18 children who had had surgery for cholesteatoma. We compared DWI and delayed T1-weighted images following gadolinium administration with intraoperative or follow-up findings. We calculated the sensitivity and specificity of each sequence for the diagnosis of recurrent cholesteatoma. Sensitivity to diagnose recurrent cholesteatoma was 87% for both DWI and delayed post-gadolinium sequences, specificity was 71% and 83%, respectively. Adding both sequences, the sensitivity was 87%, the specificity 100%. There was one false negative probably due to small size recurrence. In our series, DWI was reliable to diagnose recurrent cholesteatoma in children and allows avoiding surgery when negative. However, because small recurrences less than 5 mm may be missed, follow-up must be prolonged (5 years). (orig.)

    The heparin-binding epidermal growth factor-like growth factor (HB-EGF) plays an essential role in the development and invasiveness of cholesteatoma. This study may help to realize the molecular mechanisms underlying the pathogenesis of cholesteatoma and make HB-EGF a promising target for drug intervention of cholesteatoma. To detect HB-EGF expression in human surgical specimens of acquired middle ear cholesteatoma and analyze its functional role as a regulator of epithelial keratinocytes hyperproliferation. A total of 34 patients who underwent surgical treatment for middle ear cholesteatoma were recruited in the study. The mRNA and protein expression of HB-EGF in middle ear cholesteatoma tissues and normal postauricular skin tissues was investigated by real-time quantitative reverse-transcription-polymerase chain reaction (RT-qPCR), immunohistochemical staining, and western blot. The correlation between bone resorption degree and HB-EGF expression was also analyzed. On average, compared with normal postauricular skin, expression of HB-EGF mRNA in the cholesteatoma epithelium was significantly elevated 2.41-fold by RT-qPCR, and HB-EGF protein significantly upregulated 2.32-fold by western blot. Positive HB-EGF immunostaining observed in the basal and suprabasal layers of cholesteatoma epithelium was significantly stronger than in normal postauricular skin. Meanwhile, an obviously positive correlation between HB-EGF protein expression and bone resorption degree was discovered.

    Twenty-eight patients with cholesteatoma were studied preoperatively by means of CT petrous bone to determine the localization and extension of their lesion. All the patients underwent survey and the intraoperative findings were compared with those resulting from CT. The reading was carried out with no knowledge of the intraoperative data. The following results were obtained: localization of cholesteatoma in attic, antrum and posterior tympanic cavity had a sensitivity of 0.91 and a specificity of 0.57, with a Fisher's p value less than 0.0005. When the erosion produced by the cholesteatoma was studied in the different structures, the accuracy was greatest with the stape, the septum and prussak's space; the highest number of false negatives corresponded to the tympanic membrane. The false positives were produced in the assessment of the facial canal, tegmen tympani and the labyrinthine fistula. The reliability of CT was very high for the diagnosis of ossicular destruction and displacement of the small bones, as well as for the state of the mastoid cells and congenital variations. In conclusion, we point out the importance of performing a CT study prior to surgery for cholesteatoma due to its elevated sensitivity in locating the lesion, and we stress the value of the knowledge of the erosion of the different structures since it constitutes a guide for intraoperative exploration and assessment.

    Recent advances in otologic surgical techniques, involving the use of an operation microscope, have led to increased demands in accurate radiological diagnosis of the temporal bone. However, the difficulties of roentgen diagnosis of cholesteatoma of the middle ear are frequently experienced. Authors reviewed a total of 248 cases of mastoid roentgenograms (165 cases of cholesteatoma and 83 cases of chronic otitis media without cholesteatoma) surgically proven at Seoul National University Hospital from March 1977 to June 1980 in order that diagnostic value of routine mastoid roentgenogram (Towne and Law views) could be determined. The results are as follows; 1. Detection rate of cholesteatoma is 68.5% with Towne view only and 62.4% with Law view only, while both Towne and Law views, it is increased up to 73.9%. 2. False positive is 10.8% even with both Towne and Law views. 3. A new simple technique, transorbital magnification view, is introduced to visualize the detailed anatomic structures of the ear

    The objective of this study was to analyze the results of endoscopy-assisted ear surgery for the treatment of chronic otitis media with cholesteatoma, adhesion, or retraction pockets.Fifty-one patients who underwent oto-endoscopy-assisted canal wall up tympanomastoid surgery and/or limited anterior atticotomy with tympanoplasty for chronic otitis media with cholesteatoma, adhesion, or retraction pocket from 2006 to 2013 have been included in this study. Eradication of the disease from the middle ear and mastoid air cells was achieved by combination of the oto-microscobic and oto-endoscopic approaches. Second look surgery was performed 18 months later from the initial surgery in selected patients. Age, gender, pre-/postoperative otoscopy findings/audiograms, type of the used prostheses, and follow-up time were obtained from the patient's file. Anatomic integrity rates of the tympanic membrane, the mean gains of air bone gap, on pure-tone audiogram at 4 frequencies and existence of the residual disease were reviewed parameters. Functional evaluation was made in patients with intact tympanic membrane.Of the 51 patients, the ratios of the chronic otitis media with cholesteatoma and isolated adhesive otitis or retraction pocket cases were 74.5% (38/51) and 25.5% (13/51), respectively. Ossicular chain reconstruction was made with PORP in 27 patients and TORP in 20 patients, whereas the ossicular chain was intact in 4 patients. Anatomic integrity rates of the tympanic membrane were 90.2% (46/51). The overall (n = 46) pre-/postoperative mean ABG obtained at 4 frequencies were 28.3 ± 12.26 and 9.18 ± 5.68 dB (P otitis media with cholesteatoma patients. However, there was no recurrence or new cholesteatoma formation in isolated retraction pockets or adhesive otitis patients.Oto-endoscopic eradication of the cholesteatoma or epithelial tissue from hidden area after the all visible cholesteatoma removal by oto-microscope improves the quality of surgery

    To evaluate the usefulness of Hounsfield unit (HU) measurements for diagnosing of congenital cholesteatoma. A total of 43 patients who underwent surgery due to middle ear cavity lesions were enrolled. Twenty-one patients were confirmed to have congenital cholesteatoma by histopathological results and the other 22 patients were confirmed to have otitis media (OM) by operation. Their computed tomography images were retrospectively reviewed. We measured HU of the soft tissue mass in the middle ear cavity. In addition, we evaluated the largest diameter and location of the mass, the presence of bony erosion in the ear ossicle, and the status of the tympanic membrane in the cholesteatoma group. The mean HU was 37.36 ± 6.11 (range, 27.5-52.5) in the congenital cholesteatoma group and 76.09 ± 8.74 (range, 58.5-96) in the OM group (p < 0.001). The cut-off value was 55.5. The most common location for congenital cholesteatoma was the mesotympanum, and ear ossicle erosion was present in 24%. All patients had an intact tympanic membrane. HU measurement may be useful as an additional indicator to diagnose congenital cholesteatoma.

    Objective was to compare the consistency rates of pre- and intra-operative radiological findings in patients with chronic suppurative otitis media (CSOM). In a cross-sectional study, 80 patients with CSOM underwent pre-operative CT scanning and we compared the results with intra-operative clinical findings during mastiodectomy from 2000-2004 in the Otology Department, Amiralmomenin Hospital of Guilan Medical University, Rasht, Iran. Sensitivity, specificity, positive and negative predictive value of CT scan in tympanic and mastoid cholesteatoma, ossicular chain erosion, tegmentympani erosion, dehiscence of facial canal, lateral semicircular canal (LSCC) fistula were assessed. Then, correlation between radiological findings and intra-operative findings were calculated. The mean age of patients was 27.9+-16.3 years. Mostly were males (n=57 [71.3%]). Correlation of preoperative radiological images with intra-operative clinical findings were moderate to good on tympanic cholesteatoma, mastoid cholesteatoma and ossicular chain erosion, but weak and insignificant in cases of tegmen erosion, facial canal dehiscene and LSCC fistulae. Preoperative CT scan may be helpful in decision-making for surgery in cases of cholesteatoma and ossicular erosion. Despite of limitations radiological scanning is a useful adjunct to management of CSOM. (author)

    Since the advent of antibiotics, otogenic complications have decreased considerably. However, incomplete antibiotic therapy has altered the clinical course of middle ear disease so as to be more insidious. This paper reports a case of Bezold's abscess associated with cholesteatoma. A 48-year-old man visited our hospital presenting with a 4-day history of right otorrhea and a tender swelling in the right neck. Physical examination showed a febrile patient (38.8 degrees C) with right facial paresis and trismus. A hyperemic, hard and tender swelling was observed in his right neck from the lateral cervical to the mental region. The tympanic membrane was invisible because of granulation and swelling of the posterior wall of the external auditory canal. Intravenous clindamycin and ceftazidime therapy was started immediately. A CT-scan revealed a diffuse shadow with bony destruction in the right mastoid cortex. Extensive abscess formation was also found in the right sternocleidomastoid muscle, in the anterior neck and in the posterior neck. He was diagnosed as having Bezold's abscess associated with cholesteatoma. Radical mastoidectomy and drainage of the neck abscess was performed on the third day under general anesthesia. The mastoid cavity was found to be filled with pus and cholesteatoma debris. A small area of defective bone was found at the mastoid tip, through which there were communications between the mastoid cavity and the abscesses in the neck. Bony destruction was also found in the horizontal and vertical portion of the facial canal. Bacteroides and three kinds of gram-negative rods were cultured from the mastoid cavity.(ABSTRACT TRUNCATED AT 250 WORDS)

    Primary Ciliary Dyskinesia (PCD) describes a group of inherited disorders that result in abnormal ciliary motion leading to mucous stasis. Clinical features include almost universally otitis media with effusion (OME), particularly in infants. PCD patients provide us with a cohort of patients with OME that is not treated with ventilatory tube (VT) insertion as these have been shown to result in frequent complications including chronic otorrhoea, early extrusion and persistent perforation without significant improvement to hearing in the long term. This cohort was used to investigate whether children with PCD and OME not treated with VT were predisposed to cholesteatoma formation in the setting of a paediatric quaternary referral centre. A retrospective chart review was performed of all the children attending a multi-disciplinary PCD clinic at a national quaternary referral centre with a diagnosis of OME. We reviewed otoscopic findings, and audiometry and tympanometry results. We assessed the children in four groups: Watchful waiting, hearing aids, VT, and VT and hearing aids. One-hundred-and-one of 107 patients included in the study had a diagnosis of otitis media with effusion. No child with OME and PCD was diagnosed with a cholesteatoma during the follow up period. The only children who had insertion of a ventilatory tube were those who had the procedure prior to the formal diagnosis of PCD. We found a significant complication rate in the children with VT insertion. Hearing improved over time. The prevalence of retraction pockets in untreated OME was 1.72% (3 out of 174 ears). In children with PCD, OME is an almost universal finding in younger children, but not in adolescents. The study supports the current preference to avoid VT insertion in children with PCD as it confers a significantly higher rate of complications. No cases of cholesteatoma were found in this cohort of PCD children with OME managed without VTs. Crown Copyright © 2017. Published by Elsevier B

    The levels of expression of various C-type lectin receptors (CLRs) messenger ribo nucleic acids (mRNAs) were significantly higher in cholesteatomas than in normal skin, suggesting that these CLRs may be involved in the pathogenesis of cholesteatoma. Altered expression of pattern recognition receptors may be associated with immune responses in patients with cholesteatoma. This study assessed the levels of expression of CLR mRNAs in normal skin and in cholesteatoma. Cholesteatoma specimens were obtained from 38 patients with acquired cholesteatoma. The levels of expression of various CLR mRNAs were assessed quantitatively using real-time RT-PCR (Reverse transcription polymerase chain reaction) and correlated with age, sex, the presence of bacteria, hearing level, frequency of surgery, and degree of ossicle destruction. The levels of CD206 (cluster of differentiation 206), DEC-205 (Dendritic and epithelial cell-205), MGL (monoacylglycerol lipase), CLEC5A (C-type lectin domain family 5 member A), Dectin-2 (dendrite cell-associated C-type lectin-2), BDCA2 (Blood dendritic cell antigen 2), Mincle, DCIR (dendritic cell immunoreceptor), Dectin-1, MICL (Myeloid inhibitory C type-like lectin), and CLEC12B (C-type lectin domain family 12, member B) mRNAs were significantly higher in cholesteatoma than in control skin samples (p C-type lectin domain family 5 member) and Dectin-1 mRNAs were significantly higher in cholesteatomas with ≥2 than ≤1 destroyed ossicles (p < 0.05), and the levels of MGL, Mincle, Dectin-1, and CLEC12B mRNAs were significantly higher in recurrent than initial cholesteatoma specimens (p < 0.05). The level of CLEC5A mRNAs was significantly higher in patients with severe than mild-to-moderate hearing loss (p < 0.05).

    Ras-related C3 botulinum toxin substrate 1 (RAC1) is a 21-kDa signaling G protein that functions as a pleiotropic regulator of many cellular processes including epithelial differentiation. RAC1 activates the nicotinamide adenine dinucleotide phosphate oxidase complex which promotes formation of reactive oxygen species and degradation enzymes. RAC1 has been associated with rapid epithelial differentiation and invasive properties in human cholesteatoma. This study aimed to identify the presence of RAC1 in human cholesteatoma and analyze its functional role as a regulator of proteolysis and overgrowth. Tissue samples from human cholesteatoma and normal postaural skin were obtained from patients during otologic surgery for cholesteatoma. The expression of RAC1 mRNA was quantified by real-time RT-PCR, and localization of RAC1 expression was confirmed using immunohistochemical staining. Expression of RAC1 mRNA in the epithelium of cholesteatoma was significantly elevated 2.94 fold on average, compared with normal control skin. RAC1 expression in the suprabasal and basal layer of cholesteatoma epithelium was stronger than normal control skin. Our results suggest that RAC1 can be associated with rapid epithelial differentiation and invasive properties of human cholesteatoma.

    The modes and incidences of bone destruction in the middle ear cholesteatoma were evaluated by high resolution computed tomography, comparing with chronic otitis media with central perforation (COM) as control. The head of the malleus, the body and long process of the incus were more markedly destroyed in cholesteatoma than in COM with statistical significance. With the further extension of cholesteatoma into the antrum, the tegmen of the aditus ad antrum, the lateral semicircular canal, the handle of the malleus and the Korner's septum were involved in bone destruction.

    To compare the number of fungiform taste buds among patients with chronic otitis media (COM), those with pars flaccida retraction type cholesteatoma, and those with pars tensa retraction type cholesteatoma in combination with gustatory function. Thirty-seven patients with COM, 22 patients with pars flaccida retraction type cholesteatoma, and 17 patients with pars tensa retraction type cholesteatoma were included. An average of 10 fungiform papillae (FP) per patient in the midlateral region of the tongue were observed by confocal laser scanning microscopy in vivo, and the average number of taste buds were counted. Just before the observation of FP, electrogustometry (EGM) was performed to evaluate gustatory function. A significant decrease of the average number of fungiform taste buds and significant elevation of EGM thresholds were clarified in the pars tensa retraction type cholesteatoma group but not in the COM or pars flaccida type cholesteatoma group. It was suggested that some neurotoxic cytokines produced by cholesteatoma tissue might affect the CTN morphology, resulting in a decreased number of fungiform taste buds and elevation of EGM threshold in patients with pars tensa retraction type cholesteatoma. © The Author(s) 2016.

    Currently, there is only limited and contradictory evidence of the role of diffusion-weighted MRI (DW-MRI) in the management of children with cholesteatoma. To provide surgically controlled data that may allow to replace second-look surgery by non-echoplanar DW-MRI in children. Fifty-five children and adolescents with a median age of 8.6 years (2.2-17.7 years) underwent 61 preoperative half-Fourier acquisition single-shot turbo spin-echo (HASTE) DW-MRI of their petrous bone. Surgical interventions followed within 24 h (79%), within 5 months (20%) or at 18 months (1 case). Surgery detected a cholesteatoma or retraction pocket in 41 of 61 cases (67%). In 49 cases (80%), the MR result was confirmed by surgical findings. Two MR findings were false-positive and 10 false-negative (including cholesteatomas <4 mm). HASTE DW-MRI alone had a sensitivity of 76% and a specificity of 90%. The positive predictive value was 94%, the negative predictive value 64%. In combination with preoperative otoscopy, sensitivity was 90% and negative predictive value 82%. DW-MRI correctly detected the majority of lesions but could not reliably exclude small cholesteatomas and empty retraction pockets. We would therefore not generally recommend MR as a substitute for second-look surgery. (orig.)

    The nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome plays an important role in the pathogenesis of middle ear diseases. Modulation of inflammasome-mediated inflammation may be a novel therapeutic strategy for cholesteatoma and chronic otitis media. NLRP3 inflammasome is a critical molecule mediating interleukin (IL)-1β responses. However, the expression of NLRP3 in the pathogenesis of cholesteatoma and chronic otitis media has not been fully examined. This study sought to assess the expression of NLRP3, ASC (apoptosis-associated speck-like protein containing a caspase recruitment domain and a pyrin domain), and caspase-1 in middle ear tissues in patients with cholesteatoma or chronic otitis media. Middle ear tissue samples were obtained from patients with cholesteatoma or chronic otitis media. Control middle ear samples were collected during cochlear implant surgery of patients without middle ear inflammation. The expression of NLRP3, ASC, and caspase-1 were examined by reverse transcription polymerase chain reaction (RT-PCR) assay and immunohistochemical study. The levels of mRNA of NLRP3, ASC, and caspase-1 were significantly elevated in cholesteatoma and chronic otitis media as compared with that of normal controls. The proteins of NLRP3, ASC, and caspase-1 were observed in infiltrating inflammatory cells in cholesteatoma and chronic otitis media.

The lipids are reorganized into multiple long sheets of lamellar structures that embrace the keratinized corneocytes......, as seen in the formation and maintenance of the cutaneous permeability barrier. In this study we draw the attention to the facts that the cholesteatoma epithelium is capable of producing not only cholesterol, but also several lipids, and that the lipid molecules are organized in multilamellar structures......Specimens from primary cholesteatomas were examined under the electron microscope using a lipid-retaining method that is best suited for intracellular lipids and a method that is best for intercellular lipids.

    To investigate the different pathways of progression to the middle ear in keratosis obturans (KO) and external auditory canal cholesteatoma (EACC). Retrospective case review. Referral hospital otolaryngology department. Patients with KO or EACC and middle ear disease who underwent surgical management were included. Four ears of 4 patients (mean age, 41.25 yr) were the KO group, and 5 ears of 4 patients (mean age, 49.5 yr) were the EACC group. Intraoperative findings of the middle ear cavity were investigated in KO and EACC groups. In the KO group, 3 patients had a perforated tympanic membrane and cholesteatoma in the tympanic cavity. The other patient had preoperative right facial palsy. Removal of the keratin plug revealed an adherent tympanic membrane. In intraoperative findings, the tympanic segment of the fallopian canal was found to be eroded because of inflammation. No case initially progressed to the mastoid cavity. Four patients had external auditory canal cholesteatoma with middle ear disease. In EACC group, all patients had initial progression to the mastoid cavity. KO tends to progress initially to the tympanic cavity via a diseased tympanic membrane. EACC tends to progress to the mastoid cavity via destruction of the posterior bony canal. This is the first report to investigate differences in pathway of progression to the middle ear cavity in these 2 diseases.

    Full Text Available El colesteatoma es una estructura quística caracterizada por la presencia de epitelio escamoso productor de queratina, que sustituye o recubre la mucosa normal en la hendidura del oído medio y ápex petroso, y puede ser causa de hipoacusia irreversible, destrucción ósea y graves complicaciones por su crecimiento expansivo. Clásicamente se describen los colesteatomas en congénitos y adquiridos. La etiología de su formación es multifactorial y continúa siendo poco claro y controversial. Se reportan diferentes teorías que han tratado de explicar el colesteatoma congénito, la transición de un bolsillo de retracción hasta la aparición del colesteatoma adquirido primario, y otras en la génesis del colesteatoma adquirido secundario. Se describe la presencia de algunas citoquinas dentro del colesteatoma que inducen la hiperproliferación e invasión incoordinada de los queratinocitos de la piel del conducto auditivo externo y la pars fláccida, más agresiva en el colesteatoma adquirido pediátrico, y que desempeñan un papel fundamental en la proliferación y en la apoptosis del queratinocito. En cultivo in vitro de una muestra de tejido colesteatomatoso, se ha identificado recientemente que el TNF-a estimula la producción de la IL-8. Se considera de interés ofrecer esta revisión sobre la etiología del colesteatoma, que aún se mantiene en el campo de la investigación y continúa siendo un reto para los otocirujanos por su alta incidencia de recidivas y posibles complicaciones.Cholesteatoma is a cystic structure characterized by presence of squamous epithelium producing keratin substituting or recovering the normal mucosa in the groove of middle ear and petrous apex and may to be caused by irreversible hypoacusia, bone destruction and severe complications due to its expansive growth.

    Full Text Available Abstract Background Congenital cholesteatoma may be expected in abnormally developed ear, it may cause bony erosion of the middle ear cleft and extend to the infratemporal fossa. We present the first case of congenital cholesteatoma of the infratemporal fossa in a patient with congenital aural atresia that has been complicated with acute mastoiditis. Case presentation A sixteen year old Egyptian male patient presented with congenital cholesteatoma of the infratemporal fossa with congenital aural atresia complicated with acute mastoiditis. Two weeks earlier, the patient suffered pain necessitating hospital admission, magnetic resonance imaging revealed a soft tissue mass in the right infratemporal fossa. On presentation to our institute, Computerized tomography was done as a routine, it proved the diagnosis of mastoiditis, pure tone audiometry showed an air-bone gap of 60 dB. Cortical mastoidectomy was done for treatment of mastoiditis, removal of congenital cholesteatoma was carried out with reconstruction of external auditory canal. Follow-up of the patient for 2 years and 3 months showed a patent, infection free external auditory canal with an air-bone gap has been reduced to 35db. One year after the operation; MRI was done and it showed no residual or recurrent cholesteatoma. Conclusions Congenital cholesteatoma of the infratemporal fossa in cases of congenital aural atresia can be managed safely even if it was associated with mastoiditis. It is an original case report of interest to the speciality of otolaryngology.

    First branchial cleft anomalies manifest with duplication of the external auditory canal. This report features a rare case of microtia and congenital middle ear and canal cholesteatoma with first branchial fistula. External auditory canal stenosis was complicated by middle ear and external canal cholesteatoma, but branchial fistula, opening in the zygomatic root and a sinus in the helical root, may explain this feature. A canal wall down mastoidectomy with canaloplasty and wide meatoplasty was performed. The branchial cleft was excised through parotidectomy and facial nerve dissection. It should be considered that canal stenosis in such cases can induce cholesteatoma formation in the auditory canal and middle ear.

    Full Text Available BACKGROUND Chronic suppurative otitis media still remains a major cause of conductive hearing loss in our country. But, a few patients also display an added sensorineural hearing loss. MATERIALS & METHODS Hundred patients with CSOM undergoing surgery at our department were included in the study. The affected ears formed the ‘CSOM Group’ and the normal ears formed the ‘Control group’. Detailed otological history, clinical, surgical and audiometric findings were recorded and analysed. RESULTS It was inferred that CSOM associated with sensorineural hearing loss was found in small number of patients only. No correlation was established between duration of discharge and sensorineural loss. CONCLUSION Though greater SN loss was seen in patients of CSOM with cholesteatoma it was not statistically significant. Whether an early surgery in CSOM can prevent SN loss or not needs further studies.

    In patients with progressive conductive hearing loss and a normal tympanic membrane (TM), and with soft tissue density in the middle ear cavity (MEC) on temporal bone computed tomography (TBCT) scan, open-type congenital cholesteatoma (OCC) should be highly suspected and a proper surgical plan that includes mastoid exploration and second-stage operation is required. The clinical presentation of OCC is very similar to congenital ossicular anomaly (COA) presenting with a conductive hearing loss with intact TM. Therefore, it is challenging to make a correct preoperative diagnosis in patients with OCC. We evaluated the clinical characteristics of OCC compared with those of COA to find diagnostic clues useful in diagnosis of OCC. The medical records of 12 patients with surgically proven OCC and 14 patients with surgically proven COA were reviewed for demographic data, otologic history, preoperative TBCT findings, intraoperative findings, and pre- and postoperative audiologic data. There was no difference between OCC and COA based on demographic data, preoperative hearing, and ossicular status on TBCT. However, the presence of progressive hearing loss, soft tissue density in the MEC on TBCT scan, and the need for mastoid surgery and second-stage operation were significantly more frequent in OCC patients.

    We conducted a prospective, controlled study of patients with chronic otitis media and cholesteatoma (1) to examine the expression of myeloperoxidase (MPO) using immunohistochemical staining techniques and (2) to investigate the relationship between MPO activity and the degree of conductive hearing loss in these patients. Our study population included 51 adults-26 men and 25 women, aged 18 to 58 years (mean: 37.5)-who had been diagnosed with chronic otitis media and cholesteatoma by physical examination and computed tomography (study group). Another 30 patients-13 men and 17 women, aged 18 to 52 years (mean: 32.7)-who had chronic otitis media without cholesteatoma served as the control group. Following audiometric evaluations, all patients underwent appropriate surgery. Postoperatively, cholesteatoma samples were analyzed by immunostaining for MPO positivity as a marker for acute inflammation. We found that MPO activity was present in all 51 study patients (100%) but in only 10 controls (33.3%); the difference was statistically significant (pconductive hearing loss (χ(2) = 13.518; p < 0.001). We encourage further study of all steps in the process of cholesteatoma formation.

    First branchial cleft abnormalities are rare. They may involve the external auditory canal and middle ear. We describe a 6-year-old girl with congenital external auditory canal atresia, microtia, and cholesteatoma of mastoid and middle ear in addition to the first branchial cleft abnormalities. Clinical features of the patient are briefly described and the embryological relationship between first branchial cleft anomaly and external auditory canal atresia is discussed. The surgical management of these lesions may be performed, both the complete excision of the sinus and reconstructive otologic surgery.

    The role of high-resolution computed tomography (HRCT) and magnetic resonance imaging (MRI) in the diagnosis of preoperative and postoperative complications caused by acquired cholesteatomas will be described in this paper. The pre- and postoperative imaging of the temporal bone was performed with HRCT and MRI. HRCT and MRI were performed in the axial and coronal plane. MRI was done with T2 weighted and T1 weighted sequences both before and after the intravenous application of contrast material. All imaging findings were confirmed clinically or surgically. The preoperative cholesteatoma-caused complications depicted by HRCT included bony erosions of the ossicles, scutum, facial canal in the middle ear, tympanic walls including the tegmen tympani, and of the labyrinth. The preoperative cholesteatoma-caused complications depicted by MRI included signs indicative for labyrinthitis, and brain abscess. Postoperative HRCT depicted bony erosions caused by recurrent cholesteatoma, bony defects of the facial nerve and of the labyrinth, and a defect of the tegmen tympani with a soft tissue mass in the middle ear. Postoperative MRI delineated neuritis of the facial nerve, labyrinthitis, and a meningo-encephalocele protruding into the middle ear. HRCT and MRI are excellent imaging tools to depict either bony or soft tissue complications or both if caused by acquired cholesteatomas. According to our findings and to the literature HRCT and MRI are complementary imaging methods to depict pre- or postoperative complications of acquired cholesteatomas if these are suspected by clinical examination.

    Fibrous dysplasia is a slowly progressive benign fibro-osseous disease, rarely occurring in temporal bones. In these cases, most bony lesions developed from the bony part of the external auditory canals, causing otalgia, hearing impairment, otorrhea, and ear hygiene blockade and probably leading to secondary cholesteatoma. We presented the medical history of a 24-year-old woman with temporal monostotic fibrous dysplasia with secondary cholesteatoma. The initial presentation was unilateral conductive hearing loss. A hard external canal tumor contributing to canal stenosis and a near-absent tympanic membrane were found. Canaloplasty and type I tympanoplasty were performed, but the symptoms recurred after 5 years. She received canal wall down tympanomastoidectomy with ossciculoplasty at the second time, and secondary cholesteatoma in the middle ear was diagnosed. Fifteen years later, left otorrhea recurred again and transcanal endoscopic surgery was performed for middle ear clearance. Currently, revision surgeries provide a stable auditory condition, but her monostotic temporal fibrous dysplasia is still in place.

  17. Effects of high hydrostatic pressure on bacterial growth on human ossicles explanted from cholesteatoma patients.

    Full Text Available BACKGROUND: High hydrostatic pressure (HHP treatment can eliminate cholesteatoma cells from explanted human ossicles prior to re-insertion. We analyzed the effects of HHP treatment on the microbial flora on ossicles and on the planktonic and biofilm states of selected isolates. METHODOLOGY: Twenty-six ossicles were explanted from cholesteatoma patients. Five ossicles were directly analyzed for microbial growth without further treatment. Fifteen ossicles were cut into two pieces. One piece was exposed to HHP of 350 MPa for 10 minutes. Both the treated and untreated (control pieces were then assessed semi-quantitatively. Three ossicles were cut into two pieces and exposed to identical pressure conditions with or without the addition of one of two different combinations of antibiotics to the medium. Differential effects of 10-minute in vitro exposure of planktonic and biofilm bacteria to pressures of 100 MPa, 250 MPa, 400 MPa and 540 MPa in isotonic and hypotonic media were analyzed using two patient isolates of Staphylococcus epidermidis and Neisseria subflava. Bacterial cell inactivation and biofilm destruction were assessed by colony counting and electron microscopy. PRINCIPAL FINDINGS: A variety of microorganisms were isolated from the ossicles. Irrespective of the medium, HHP treatment at 350 MPa for 10 minutes led to satisfying but incomplete inactivation especially of gram-negative bacteria. The addition of antibiotics increased the efficacy of elimination. A comparison of HHP treatment of planktonic and biofilm cells showed that the effects of HPP were reduced by about one decadic logarithmic unit when HPP was applied to biofilms. High hydrostatic pressure conditions that are suitable to inactivate cholesteatoma cells fail to completely sterilize ossicles even if antibiotics are added. As a result of the reduced microbial load and the viability loss of surviving bacteria, however, there is a lower risk of re-infection after re-insertion.

    The use of lasers in cholesteatoma surgery is common and well accepted. The most commonly used laser fibres are straight and non-adjustable; these have several limitations. This paper describes the use of an alternative laser fibre. This 'How I Do It' paper describes and illustrates the use of an alternative curved adjustable fibre-optic diode laser in microscopic cholesteatoma surgery. The curved, adjustable laser fibre allows accurate and atraumatic disease removal when the use of a straight laser fibre may be less effective or accurate. It reduces potential damage to delicate structures without the need for extra drilling or bone removal. It is suggested that the curved adjustable laser fibre is superior to the traditional straight fibre for cholesteatoma surgery.

    To investigate the role of fibroblasts in the pathogenesis of cholesteatoma. Tissue specimens were obtained from our patients. Middle ear cholesteatoma-derived fibroblasts (MECFs) and postauricular skin-derived fibroblasts (SFs) as controls were then cultured for a few weeks. These fibroblasts were stimulated with interleukin (IL) 1alpha and/or IL-1beta before gene expression assays. We used the human genome U133A probe array (GeneChip) and real-time polymerase chain reaction to examine and compare the gene expression profiles of the MECFs and SFs. Six patients who had undergone tympanoplasty. The IL-1alpha-regulated genes were classified into 4 distinct clusters on the basis of profiles differentially regulated by SF and MECF using a hierarchical clustering analysis. The messenger RNA expressions of LARC (liver and activation-regulated chemokine), GMCSF (granulocyte-macrophage colony-stimulating factor), epiregulin, ICAM1 (intercellular adhesion molecule 1), and TGFA (transforming growth factor alpha) were more strongly up-regulated by IL-1alpha and/or IL-1beta in MECF than in SF, suggesting that these fibroblasts derived from different tissues retained their typical gene expression profiles. Fibroblasts may play a role in hyperkeratosis of middle ear cholesteatoma by releasing molecules involved in inflammation and epidermal growth. These fibroblasts may retain tissue-specific characteristics presumably controlled by epigenetic mechanisms.

    Girls with Turner syndrome are prone to cholesteatoma, a serious suppurative middle ear disease. We aimed to confirm its high prevalence in Turner syndrome, identify risk factors and suggest possible strategies for earlier detection. We reviewed 179 girls with Turner syndrome between 1989 and 2012 to identify cases of cholesteatoma. Seven girls (3.9%) had cholesteatoma (index girls) and each was compared with three age-matched girls without cholesteatoma (comparison girls). All the index girls had either the 45,X or 45,X/46X,i(Xq) karyotypes. Nine ears were initially affected, with three recurrences in two girls. Median age at first cholesteatoma presentation was 11.9 years (range: 7.5-15.2), with otorrhoea for three (range: one to seven) months in all 12 affected ears. Index girls had a significantly higher proportion of previous recurrent acute (p = 0.007) and chronic otitis media (p = 0.008), chronic perforation (p = 0.038) aural polyps (p Turner syndrome. Risk factors include 45,X and 46,XiXq karyotypes; a history of chronic otitis media, tympanic membrane retraction and persistent otorrhoea; and older age. Earlier recognition of ear disease is needed and otoscopy training for paediatricians caring for Turner syndrome patients may be beneficial. ©2014 Foundation Acta Paediatrica.

    patients with COM, with or without cholesteatoma, the malleus status is a significant predictor of postoperative hearing outcome, independent of the stapes condition. Studies reporting on individual ossicle status supported this finding by showing that only malleus condition influenced postoperative hearing outcome. These findings are based on level IV evidence, which indicates the need for future high-level evidence studies.

    Bone homeostasis is maintained by a balance in activity between bone-resorbing osteoclasts and bone-forming osteoblasts. Shifting the balance toward bone resorption causes osteolytic bone diseases such as rheumatoid arthritis and periodontitis. Osteoclast differentiation is regulated by receptor activator of nuclear factor κB ligand (RANKL), which, under some pathological conditions, is produced by T and B lymphocytes and synoviocytes. However, the mechanism underlying bone destruction in other diseases is little understood. Bone destruction caused by cholesteatoma, an epidermal cyst in the middle ear resulting from hyperproliferation of keratinizing squamous epithelium, can lead to lethal complications. In this study, we succeeded in generating a model for cholesteatoma, epidermal cyst-like tissue, which has the potential for inducing osteoclastogenesis in mice. Furthermore, an in vitro coculture system composed of keratinocytes, fibroblasts, and osteoclast precursors was used to demonstrate that keratinocytes stimulate osteoclast differentiation through the induction of RANKL in fibroblasts. Thus, this study demonstrates that intercellular communication between keratinocytes and fibroblasts is involved in the differentiation and function of osteoclasts, which may provide the molecular basis of a new therapeutic strategy for cholesteatoma-induced bone destruction.

  5. Infectious Causes of Cholesteatoma and Treatment of Infected Ossicles prior to Reimplantation by Hydrostatic High-Pressure Inactivation

    2015-01-01

    Chronic inflammation, which is caused by recurrent infections, is one of the factors contributing to the pathogenesis of cholesteatoma. If reimplantation of autologous ossicles after a surgical intervention is intended, inactivation of planktonic bacteria and biofilms is desirable. High hydrostatic pressure treatment is a procedure, which has been used to inactivate cholesteatoma cells on ossicles. Here we discuss the potential inactivating effect of high hydrostatic pressure on microbial pathogens including biofilms. Recent experimental data suggest an incomplete inactivation at a pressure level, which is tolerable for the bone substance of ossicles and results at least in a considerable reduction of pathogen load. Further studies are necessary to access how far this quantitative reduction of pathogens is sufficient to prevent ongoing chronic infections, for example, due to forming of biofilms. PMID:25705686

    Full Text Available Introduction: Cholesteatomas are cystic lesions encased by stratified squamous epithelium, filled for keratin. They are classified in congenital, about of 2-5% and acquired, which are subdivided in primary formed from a tympanic retraction and secondary, originated from epithelium migration through a tympanic perforation. They are tumeurs with an expansive capacity and of bone lysis being able to invade adjacent structures. Case Report: This work reports the case of ONV, 23 years old from Macapá/Amapá. In august 2007, he/she appeared to attendance with a case history of right chronic otorrhea, he/she also reported meningitis and progressive right peripherica facial paralysis. The mastoid tomography demonstrated an hypodense image with density of soft tissues filling the middle ear, destructing the ossicular chain, semicircular canals, cochlea and extending until next to the proximal portion of the internal auditory meatus. He/she was referred to surgery. During the trans-operative it is evidenced an extensive destruction of the cortical layer of the mastoid, which was obstructed by a mass of an yellow coloration, fetid and of the consistent aspect. After the lesion is removed it is verified the presence of fistulae of high debit with posterior fossa. It was proceeded with the fistulae closing with a bone wax and temporal muscle shred. The patient remained confined during 15 days in use wide antimicrobial schema. Currently, it is find in regular accompaniment and in a good general state. Final Comments: This work aims to call attention to the rigorous complications of these pathologies , which despite to be common and to be a benign tumoral lesion can bring severe sequelae to the patient, in the event of the diagnosis and treatment not to be prematurely performed.

    The first reported case of facial paralysis due to an inflammatory pseudotumor (IPT) of the facial nerve as a complication of epidermal nevus syndrome (ENS) is herein presented. A 10-month-old female patient was diagnosed with ENS at 3 months of age. She was referred to us because of moderate left facial paralysis. Epidermal nevi of her left auricle extended deep into the external ear canal. Otoscopy revealed polypous nevi and cholesteatoma debris filling the left ear. Computed tomography showed a soft mass filling the ear canal, including the middle ear, and an enormously enlarged facial nerve. Surgical exploration revealed numerous polypous nevi, external ear cholesteatoma, and tumorous swelling of the facial nerve. The middle ear ossicles were completely lost. The facial paralysis was improved after decompression surgery, but recurred 5 months later. A second operation was conducted 10 months after the first. During this operation, facial nerve decompression was completed from the geniculate ganglion to near the stylomastoid foramen. Histological diagnosis of the facial nerve tumor was IPT probably caused by chronic external ear inflammation induced by epidermal nevi. The facial paralysis gradually improved to House-Blackmann grade III 5 years after the second operation. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

    Objective: to determine the aspects and frequency of middle ear alterations at computed tomography and magnetic resonance imaging in patients with clinical suspicion for middle ear inflammatory disease. Material and method: imaging examination results of 95 patients (95 computed tomography and 1 magnetic resonance imaging) were compared with the results of otology, imaging and surgical findings. Results: fifty-two patients had normal imaging results. Forty-three patients had radiologic alterations compared to the physical, otology and histopathologic exams: acute otomastoiditis in 2 patients (4.6%), unilateral chronic otomastoiditis in 9 (21.0%), bilateral chronic otomastoiditis in 2 (4.6%), unilateral cholesteatoma in 26 (60.5%), and bilateral cholesteatoma in 4 (9.3%). Conclusion: computed tomography was able to demonstrate the characteristics of the lesions and found complications in majority of the cases. Magnetic resonance imaging was used only in one patient to rule out scar and cholesteatoma. The knowledge of the clinical and otologic data enables the radiologist to elaborate a more appropriate interpretation of the imaging findings. (author)

    We conducted a retrospective study to compare the clinical characteristics of external auditory canal cholesteatoma (EACC) with those of a similar entity, keratosis obturans (KO). We also sought to identify those aspects of each disease that may lead to complications. We identified 6 patients in each group. Imaging studies were reviewed for evidence of bony erosion and the proximity of disease to vital structures. All 6 patients in the EACC group had their diagnosis confirmed by computed tomography (CT), which demonstrated widening of the bony external auditory canal; 4 of these patients had critical erosion of bone adjacent to the facial nerve. Of the 6 patients with KO, only 2 had undergone CT, and neither exhibited any significant bony erosion or expansion; 1 of them developed osteomyelitis of the temporal bone and adjacent temporomandibular joint. Another patient manifested KO as part of a dermatophytid reaction. The essential component of treatment in all cases of EACC was microscopic debridement of the ear canal. We conclude that EACC may produce significant erosion of bone with exposure of vital structures, including the facial nerve. Because of the clinical similarity of EACC to KO, misdiagnosis is possible. Temporal bone imaging should be obtained prior to attempts at debridement of suspected EACC. Increased awareness of these uncommon conditions is warranted to prompt appropriate investigation and prevent iatrogenic complications such as facial nerve injury.

    To assess the degree of reliability of computed tomography (CT) and the agreement between the imaging studies and intraoperative findings in chronic otitis media (COM) with cholesteatoma. We studied 51 patients diagnosed clinically as having inflammatory disease of the middle ear. All the patients under-went high-resolution Ct of temporal bone in axial and coronal planes. The imaging studies were retrospectively correlated with the intraoperative findings and the sensitivity of CT in the detection of erosive cholesteatoma was determined. Open radical mastoidectomy is the surgical technique most frequently used to treat cholesteatoma in our center. The greatest radio-surgical correlation was achieved in the detection of masses presenting soft tissue attenuation in air-filled cavities in middle ear (100%) and in bone erosion (87.5%). The 20 patients (39%) who were diagnosed as having COM with cholesteatoma underwent surgical treatment in our center. CT is the technique of choice in the study of COM with cholesteatoma, providing basic and necessary information for the image-based diagnosis of this disease, the detection of masses presenting soft tissue attenuation and bone erosion. We also point out the role of CT as an intraoperative guide and discuss its low sensitivity for the detection of small areas of dura mater exposure, ossicular luxation and facial canal dehiscence.

    A case of chronic chemical meningitis occurring after a radical mastoidectomy is reported. Imaging and surgical findings were suggestive of a dissemination of cholesteatoma debris within the subarachnoid spaces. Chemical meningitis has been described in epidermoid and dermoid cyst rupture. This report illustrates that clinicians should be aware of this possible complication. Skull base imaging is mandatory before considering the diagnosis of idiopathic meningitis. Only treatment of the abnormal communication between cerebrospinal fluid and middle ear may eradicate the origin of this rare meningitis. (orig.) With 6 figs., 15 refs.

    To analyze the clinical characteristics of unilateral conductive hearing loss with intact tympanic membrane, and summarize the key diagnostic points, differential diagnosis and observe the effects of surgical treatment. We reviewed data from 82 patients with unilateral conductive hearing loss with intact tympanic membranes who accepted the exploratory tympanotomy from April 2011 to September 2013. There were 41 males and 41 females, aged from 7 to 66( averaged 26.5±13.7)years, with a history of one month to 50 years. The history, clinical symptoms, audiological evaluation, high resolution temporal bone CT, the results of surgical exploration and hearing reconstruction were analyzed. The exploratory tympanotomy revealed 43 cases of congenital middle ear malformations (52.4%), 22 cases of otosclerosis (26.8%), eight cases of congenital cholesteatoma (9.8%), six cases of trauma induced conductive hearing loss (7.3%), three cases of congenital ossicular malformations with congenital cholesteatoma (3.7%). Progressive hearing loss was common in patients with otosclerosis and congenital cholesteatoma, and patients with congenital middle ear malformations described their hearing loss since childhood. High resolution temporal bone CT of congenital middle ear malformation, trauma induced conductive hearing loss, congenital cholesteatoma diagnosis rate was 40.0%, 50.0%, and 83.3% respectively. The preoperative air-conductive threshold of patients with absence of the oval window were increased to (66.9±1.1)dBHL, the preoperative bone-conductive threshold achieved (28.3±10.4)dBHL at 2 000 Hz. While patients with stapes fixation and that with ossicular chain discontinuity were (27.2±9.7)dBHL and (17.8±8.8)dBHL(P=0.000)respectively. Through the tympanic exploration with endaural incision under the microscope, different hearing reconstruction were applied according to different lesions. After the operation, the hearing level of 52 patients with return visit were improved, the

    properties which may cause destruction of the bone and lead to complications. Substances such as cytokeratin (CK 16 and Ki-67 are some of the markers of cellular proliferation and have been used to study this disease. CK 16 is a protein filament located in the cytoplasm of epithelial cells and typical of hyperproliferating epithelium. Ki-67 is a nuclear antigen found in cells that are in the proliferating stage. Aim: The objective of this research project was to study the expression of CK 16 and Ki-67 in acquired cholesteatomas. Study design: Clinical prospective. Material and Method: Samples were obtained from 31 patients submitted to otologic surgery for the removal of a middle ear cholesteatoma from 1998 to 2000. Twenty patients were adults and 11 were children. Samples were studied by histology and by immunohystochemistry for the expression of CK16 and Ki-67 in the matrix of the cholesteatoma. Results: CK 16 was found in the suprabasal layers of the matrix of the cholesteatoma, and Ki-67 was found from the basal layer all the way to the suprabasal and apical layers. Reaction to anti-CK 16 and Ki-67 antibodies was heterogeneous. There was a positive and significant relation between morphological variables such as epithelial acantosis and hyperplasia of the basal layer and the presence of suprabasal CK16 and Ki-67 in the matrix. Conclusion: Based on the results of this study, the authors conclude that cholesteatomas have hyperproliferating characteristics with a significant-expression of CK16 and Ki-67 in the matrix.

    Incidental cardiovascular findings are a frequent phenomenon in computed tomography (CT) examinations. As the result of a dedicated PubMed search this article gives a systemic overview of the current literature on the most important incidental cardiovascular findings, their prevalence and clinical relevance. The majority of incidental cardiovascular findings are of only low clinical relevance; however, highly relevant incidental findings, such as aortic aneurysms, thromboses and thromboembolic events can also occasionally be found, especially in oncology patients. The scans from every CT examination should also be investigated for incidental findings as they can be of decisive importance for the further clinical management of patients, depending on their clinical relevance.

    In a prospective study of 91 patients with acute pancreatitis, computed tomographic (CT) findings were correlated with the clinical type of acute pancreatitis. In acute edematous pancreatitis (63 patients; 16 with repeat CT), CT was normal (28%) or showed inflammation limited to the pancreas (61%). Phlegmonous changes were present in 11%, including one patient with focal pancreatic hemorrhage, indicating that clinically unsuspected hemorrhagic pancreatitis can occur. In acute necrotizing (hemorrhagic, suppurative) pancreatitis (nine patients; eight with repeat CT), no patient had a normal CT scan and 89% had phlegmonous changes. One patient had hemorrhagic pancreatitis and three had abscesses. In acute exacerbation of chronic pancreatitis (10 patients; three with repeat CT), there were pancreatic calcifications (70%), a focal mass (40%), and pancreatic ductal dilation (30%). On follow-up CT, the findings of acute pancreatitis did not always disappear with resolution of the clinical symptons. This was especialy true of phlegmonous pancreatitis, where the CT findings could persist for months

    Recently, minimally invasive transcanal myringotomy (MITM), which is a useful surgical technique for early stage congenital cholesteatoma (CC) in children, was introduced. The purpose of this study is to evaluate the short-term surgical results of MITM in pediatric early stage CC. We retrospectively reviewed the charts of 24 patients who underwent MITM between January 2013 and October 2015. The patients' ages ranged from 1 to 16 years (mean, 2.6 years). There were 17 male and 7 female patients. The right side (n = 13) was affected twice as often as the left side (n = 11). The most common site was the anterosuperior quadrant (15 cases). The diameter of the CC on axial computed tomography images ranged from 2.8 to 5.7 mm (mean, 3.9 mm). CCs were graded according to Potsic's system: 18 cases were classified as stage I, 3 case as stage II, and 3 cases as stage III. AllCCs except 1 were closed type. In21 patients, the tympanic membrane closed naturally without recurrence. Three patients showed small persistent dry perforation. Natural closure occurred in these patients, who were treated with paper patches. MITM is a simple, effective technique for removing an early stage CC from the middle ear, and it can minimize operative time, length of hospitalization, and postoperative morbidity.

    Morphologic renal magnetic resonance imaging (MRI) findings in patients with nephropathia epidemica (NE) were evaluated, and these findings were correlated with the clinical course of NE. Renal MRI was performed in 20 hospitalized NE patients during the acute phase of their disease. A repeat MRI study was made 5-8 months later. Renal parenchymal volume, renal length and parenchymal thickness were decreased in all patients in the repeat study. Edema/fluid collections were found bilaterally in 16 patients in the primary MRI study. Greater change in parenchymal volume, renal length and parenchymal thickness between the primary and the repeat MRI study as well as the presence of edema/fluid collections in the primary study evinced mild association with clinical fluid volume overload, high blood pressure level, inflammation, thrombocytopenia and severe clinical renal insufficiency. Change in parenchymal volume was associated with a severe clinical course more markedly than the other MRI findings. Measurable renal MRI changes occurred in every NE patient. The severity of the findings in MRI evinced mild association with clinical fluid volume overload, high blood pressure level, inflammation, thrombocytopenia and severe clinical renal insufficiency. Based on this study and our previous ultrasound (US) findings, we prefer US as the primary examination mode in NE patients. (orig.)

    The purpose of this study is to correlate the MR findings with clinical stage and clinical outcome, and to describe the evolutional changes of abnormal MR findings of transverse myelitis. Medical records and spinal MR images of 23 patients with both clinical and radiological diagnosis of transverse myelitis were retrospectively reviewed. MR findings were correlated with clinical stages including interval between MR imaging and full development of clinical symptoms, and compared with the clinical outcome. Diffuse high signal intensity of the spinal cord on T2-weighted image with mild cord bulging (67%) and focal contrast enhancement of the cord (75%) were observed within the first four weeks after full development of clinical symptoms. The findings decreased in extent or vanished later than four weeks on either initial or follow-up MR images. Most patients with either cord atrophy or focal hemorrhage within the cord lesion had poor clinical outcome. The MR findings of transverse myelitis are nonspecific, which may be seen in a variety of diseases. Serial MRIs, especially follow-up examination over at least one month after full development of clinical symptoms are useful in the diagnosis of transverse myelitis and predicting its prognosis.

    The purpose of this study is to evaluate the findings of magnetic resonance (MR) imaging and selective spinal angiography of spinal cord arteriovenous malformations (SCAVMs) and to investigate the correlation of these findings with the development of clinical symptoms. In 16 patients diagnosed as suffering from SCAVMs, MR imaging and selective spinal angiograms were retrospectively analyzed and correlated with clinical symptoms. Clinical data were reviewed, especially concerning the mode of onset of clinical symptoms, and MR images of SCAVMs were evaluated with regard to the following parameters: spinal cord swelling with T2 hyperintensity, cord atrophy, intramedullary hemorrhage, and contrast enhancement of the spinal cord. Selective spinal angiographic findings of SCAVMs were also evaluated in terms of the following , parameters: type of SCAVM, presence of aneurysms, and patterns of venous drainage. Imaging findings were also correlated with the development of clinical symptoms. Systematic evaluation of the findings of MR imaging and angiography provides detailed information on the type of AVM and status of the spinal cord parenchyma, and this can be correlated with clinical manifestations of SCAVM. In patients suffering from this condition, spinal cord dysfunction due to venous congestion appears to be the main cause of clinical symptoms. (author). 18 refs., 2 tabs., 3 figs

    The efficacy of the preoperative 1 mm-slice CT for evaluating the condition of the ossicular chain and the facial canal was assessed. CT findings were compared with the operative findings of middle ears in 120 cases of chronic otitis media or cholesteatoma that underwent tympanoplasty. The reliability of 1 mm-slice CT in detecting any defect of the ossicular chain was much superior to those of 2 mm-slice CT previously reported, and the difference between them is essential for preoperative information. On the other hand, thinner slice than 1 mm may be unnecessary, especially in routine use. (author)

    A wide spectrum of disease entities can affect the external auditory canal (EAC). This review describes the normal anatomy of the EAC. Congenital abnormalities, infections, neoplasms, and miscellaneous conditions, such as cholesteatoma and acquired stenosis, are shown with reference to clinical relevance and management. Cases have been histologically confirmed, where relevant. The EAC is frequently imaged - for example, on cross-sectional imaging of the brain - and this review should stimulate radiologists to include it as an important area for review.

    Chronic otitis media (COM), affecting all over the world and in a wide range of age groups in Turkey, is an important cause of ear discharge and hearing loss. The main clinical manifestations are tympanic membrane perforation, ear, nose and throat problems. On the tympanic membrane perforation becomes persistent and cholesteatoma development, there are a lot of opinions today. Especially in the pathology associated with otitis media with effusion eustachian tube, it is known that COM and cholesteatoma develop. In our study, we interpreted 210 patients' temporal computed tomography (CT). Seventy of these 210 patients had otitis media with cholesteatoma, 70 patients had only otitis media without cholesteatoma, and 70 patients had no otitis media. The eustachian tubes were evaluated using temporal CT multiplanar reconstruction method. Angles with the horizontal plane of the eustachian tube and Reid and tubotympanic angles were measured. The angles between eustachian tube and horizontally oriented Reid plane of the patients with cholesteatoma were found to be significantly lower than the patients with otitis media without cholesteatoma and the patients with no history of otitis media. For the tubotympanic angle, no statistically significant differences were observed between the groups. These results suggest that the decrease in the angle with the horizontal plane of Reid in the eustachian tube in adults may play a significant role in the etiology of cholesteatoma.

    To describe the clinical characteristics and recent findings in the heterogeneous group of inherited disorders of melanin biosynthesis grouped as "albinism." The current classification of albinism, and the cutaneous, ocular, and central nervous system characteristics are presented. Recent clinical findings are summarized. Albinism is now classified based on genes known to be responsible for albinism. Foveal hypoplasia is invariably present and individuals with albinism often have delayed visual development, reduced vision, nystagmus, a positive angle kappa, strabismus, iris transillumination, and absent or reduced melanin pigment in the fundi. A visual-evoked potential can document the excessive retinostriate decussation seen in albinism. Grating acuity can be used to document delayed visual development in preverbal children. Glasses are often needed to improve visual acuity and binocular alignment. Albinism is caused by several different genes. Heterogeneity in clinical phenotype indicates that expressivity is variable.

    Greater trochanter pain syndrome due to tendinopathy or bursitis is a common cause of hip pain. The previously reported magnetic resonance (MR) findings of trochanteric tendinopathy and bursitis are peritrochanteric fluid and abductor tendon abnormality. We have often noted peritrochanteric high T2 signal in patients without trochanteric symptoms. The purpose of this study was to determine whether the MR findings of peritrochanteric fluid or hip abductor tendon pathology correlate with trochanteric pain. We retrospectively reviewed 131 consecutive MR examinations of the pelvis (256 hips) for T2 peritrochanteric signal and abductor tendon abnormalities without knowledge of the clinical symptoms. Any T2 peritrochanteric abnormality was characterized by size as tiny, small, medium, or large; by morphology as feathery, crescentic, or round; and by location as bursal or intratendinous. The clinical symptoms of hip pain and trochanteric pain were compared to the MR findings on coronal, sagittal, and axial T2 sequences using chi-square or Fisher's exact test with significance assigned as p<0.05. Clinical symptoms of trochanteric pain syndrome were present in only 16 of the 256 hips. All 16 hips with trochanteric pain and 212 (88%) of 240 without trochanteric pain had peritrochanteric abnormalities (p=0.15). Eighty-eight percent of hips with trochanteric symptoms had gluteus tendinopathy while 50% of those without symptoms had such findings (p=0.004). Other than tendinopathy, there was no statistically significant difference between hips with or without trochanteric symptoms and the presence of peritrochanteric T2 abnormality, its size or shape, and the presence of gluteus medius or minimus partial thickness tears. Patients with trochanteric pain syndrome always have peritrochanteric T2 abnormalities and are significantly more likely to have abductor tendinopathy on magnetic resonance imaging (MRI). However, although the absence of peritrochanteric T2 MR abnormalities

    To compare the differential findings of tuberculous otitis media(TOM) with those of chronic sup purative otitis media with or without cholesteatoma, as seen on high resolution temporal bone CT. We retrospectively reviewed 14 cases of TOM, 30 cases of chronic suppurative otitis media(CSOM), and 30 cases of chronic otitis media with cholesteatoma(Chole). All had been pathologically confirmed. We evaluated the preservation of mastoid cells without sclerotic change, the location and extension of soft tissue to the external auditary canal, and erosion of ossicles, the tegmen tympani, scutum, bony labyrinth, facial nerve canal and sigmoid sinus, and the presence of intracranial complications. Soft tissue in the mastoid antrum was seen in all cases of TOM(100%), 29 cases of CSOM(96.7%), and 26 cases of Chole(86.7%). In contrast, the soft tissue in the entire middle ear cavity was noted in 13 cases of TOM(92.8%), 7 cases of CSOM(23.3%), and 12 cases of Chole(40%). Soft tissue extended to the superior aspect of the external auditory canal in 4 cases of TOM (28.6%) and 5 cases of Chole (16.7%). Mastoid air cells were seen in 9 cases of TOM (64.3%), 4 cases of CSOM (13.3%), and 3 cases of Chole(10%). Ossicular erosion was noted in 6 cases of TOM (42.9%), 12 cases of CSOM (40%), and 26 cases of Chole(86.7%), while in one case of TOM (7.1%), 5 cases of CSOM (16.7%), and 15 cases of Chole(50%) there was erosion of the scutum. In one case of TOM, follow-up CT study after 9 months of antituberculous medication without surgery revealed complete clearing of previously noted soft tissue in the middle ear cavity. Specific CT findings of TOM were not seen, but if there were findings of soft tissue in the entire middle ear cavity, soft tissue extension to the external auditory canal, preservation of mastoid air cells without sclerotic change, and intact scutum, TOM may be differentiated from other chronic otitis media.

    Fascioliasis is a disease caused by the trematode Fasciola hepatica. Cholangitis is a common clinical manifestation. Although fascioliasis may show various radiological and clinical features, cases without biliary dilatation are rare. We present unique ultrasound (US) and magnetic resonance cholangiopancreatography (MRCP) findings of a biliary fascioliasis case which doesn’t have biliary obstruction or cholestasis. Radiologically, curvilinear parasites compatible with juvenile and mature Fasciola hepatica within the gallbladder and common bile duct were found. The parasites appear as bright echogenic structures with no acoustic shadow on US and hypo-intense curvilinear lesions on T2 weighted MRCP images. Imaging studies may significantly contribute to the diagnosis of patients with subtle clinical and laboratory findings, particularly in endemic regions

    Full Text Available O colesteatoma adquirido da orelha média causa erosão óssea, com altas taxas de morbidade e mortalidade. O TNF-alfa (TNF-alfa lambda uma das principais citocinas envolvidas neste processo. OBJETIVO: Avaliar o papel do TNF-alfa na reabsorsão óssea e a ação dele no colesteatoma. MATERIAL E MÉTODOS: Foi realizado um levantamento e uma revisão crítica da literatura. RESULTADOS: Todos os autores estudados concordam com a importância do TNF-alfa no processo de reabsorção óssea presente no colesteatoma e com o grau de destruição observado. Diferentes trabalhos demonstraram que o TNF-alfa é capaz de provocar erosão óssea, através de diferentes vias de ação. Ele pode estimular a diferenciação e a maturação dos osteoclastos ou, ainda, agir na matriz óssea expondo-a à ação dos osteoclastos. Existe a possibilidade de inibir a ação do TNF-alfa, diminuindo seus efeitos e prevenindo a perda óssea em doenças como a artrite reumatóide. Não existe, entretanto, trabalhos específicos em colesteatoma. Não existe consenso sobre a sua localização. Estas diferenças, provavelmente, ocorrem devido à distribuição dos receptores. CONCLUSÃO: O TNF-alfa, presente no colesteatoma promove a reabsorsão óssea, juntamente com outras citocinas (RANKL e IL-1, estando relacionado com a presença de complicações.Cholesteatoma may cause bone erosion, with high morbidity and mortality rates.

MATERIAL AND METHODS: analysis and critical literature review. RESULTS: Different studies have demonstrated that TNF-a is capable of causing bone erosion. It may stimulate the differentiation and maturation of osteoclasts or it may act on the bone matrix, exposing it to the action of the osteoclasts. It is possible to inhibit TNF-a, reducing its effects and prevent

    Parenchymal iron deposition occurs in hemochromatosis, while iron is deposited in reticuloendothelial cells after blood transfusions(Hemosiderosis). We studied correlation between MR finding and clinical findings(serum ferritin, TSI, LFT, disease duration) of hemosiderosis. 12 patients with chronic renal failure and one patient with aplastic anemia, who have received multiple transfusion, were performed MRI with a 2.0 Tesla unit. In all of 13 patients(17 cases), the liver revealed low signal intensity equal to background noise. In 4 of 17 cases whose serum ferritin level was below 1000 ng/ml, pancreas, gastric wall, adrenal gland were involved in 1 case. In 4 cases with serum ferritin level between 1000 and 1500, pancreas was involved in 2 cases, and other organ was involved in 1 case. In 9 cases with serum ferritin level above 1500ng/ml, pancreas was involved in 9 cases, and other origin 4 cases. The MR findings are well correlated with serum ferritin level whereas the TSI, LFT, disease duration are not correlated with involved organ on MR.

    To describe the clinical and radiological findings of abdominopelvic involvement in scrub typhus. Abdominopelvic computed tomography (CT) of 78 patients with scrub typhus were evaluated by two readers. The presence of gallbladder wall thickening, arterial inhomogeneous enhancement of the liver, periportal edema, splenic infarction, hepatomegaly, splenomegaly, ascites, pleural effusion, and sites of lymphadenopathy were evaluated. Patients were divided into four clinical subgroups according to laboratory findings. Association between imaging findings and subgroups was analyzed by Chi squared test or Fisher's exact test. The most common CT finding was hepatomegaly (74.4%), followed by splenomegaly (66.7%). The majority of patients had at least three areas of abdominopelvic lymphadenopathy (71.8%). Pelvic lymphadenopathy was most commonly seen when eschar was found in the ipsilateral lower extremity (left, n = 5/7; right, n = 8/13). Significant association between hepatic dysfunction and perigastric lymphadenopathy was documented (p = 0.03). Scrub typhus has a spectrum of variable clinical and radiological findings mimicking those of acute hepatitis. Diffuse abdominopelvic lymphadenopathy involving the retroperitoneum and pelvic area may aid in early diagnosis of scrub typhus. Perigastric lymphadenopathy could be a sign of severe scrub typhus combined with hepatic dysfunction.

    The posterior tympanum consists of several irregular eminences, ridges, and sinuses. These sinuses do not communicate with the mastoid air cell system, and cholesteatoma and/or granulation tissue prefer to fill them. This area cannot be visualized with ease by the usual surgical approach, and is thus quite important for surgeons. Recent developments in high-resolution computed tomography (HRCT) allow more than ever precise identification of subtle changes in the posterior tympanum. Axial HRCT sections provide essential information for the preoperative evaluation of the posterior tympanum. The performance of surgeons has been promoted both in evaluation and treatment planning of patient with suspected posterior tympanic lesions. HRCT findings were compared with the operative findings in 52 patients (54 ears) who had the operation for chronic otitis media. Important findings by HRCT diagnosis of posterior tympanum are as follows; (1) Bone destruction in the posterosuperior part of the tympanic anulus and in the lateral wall of the facial sinus are the important findings for the diagnosis of invasion of cholesteatoma in the posterior tympanum. (2) Similarly important finding is the bone destruction of the pyramidal eminence. This was found in 6 of 9 cases with cholesteatomas extending into the sinus tympani. (3) The soft tissue density in the posterior tympanum does not necessarily indicate pathological processes. Effusion in the posterior tympanum is imaged as soft tissue density, and can not be differentiated from cholesteatoma or granulation by present HRCT. (author)

    To evaluate the radiographic findings of gastrointestinal anisakiasis with clinical and pathologic correlation. In ten patients, findings were retrospectively analysed. There were two cases of the gastric variety of gastrointestinal anisakiasis and eight of the intestinal, and they were diagnosed during gastroscopy, by resection during surgery, and on the basis of typical clinical findings. All ten patients underwent both plain radiography and CT scanning of the abdomen. US was performed in five patients and an upper gastrointestinal series in one. Clinical data were evaluated with regard to a history of raw fish ingestion, time from ingestion of raw fish to onset of symptoms, location of abdominal pain, and laboratory data. Radiologic findings were analysed in terms of wall thickening and appearance, mesenteric infiltration, bowel dilatation proximal to lesion, and ascites. All patients had a history of recent ingestion of raw fish and complained of severe abdominal pain that occurred approximately 7-48 hours later. Pain occurred in the lower abdomen in five patients, the epigastrium in four, and the right lower abdomen in two. Laboratory test disclosed the leukocytosis in eight patients and eosinophilia in three. In all cases of intestinal anisakiasis, ileus was demonstrated on plain radiographs of the abdomen, while the upper gastrointestinal series showed mucosal thickening and multiple filling defects. US findings were bowel thickening and dilation, and on CT images, wall thickening revealed a target sign. Mesenteric infiltration and ascites were seen in seven patients. In four who underwent surgery, a cross-section through the lesion revealed submucosal eosinophilic granuloma with anisakis larva. Although the CT findings are non-specific, taken in conjunction with characteristic clinical findings, they may be helpful in the diagnosis of gastrointestinal anisakiasis. (author)

    To evaluate the mammographic and clinical findings of nonpalpable breast cancer. Materials and Methods : In 28 of 607 breast cancer patients examined between January 1994 and April 1997, lesions were nonpalpable. We retrospectively analyzed the mammographic, clinical and pathologic features of 25 patients (28 lesions) whose mammograms we obtained. Results : Among these 25 patients (28 lesions) screening was abnormal in 22; other symptoms were bloody nipple discharge(n=4), and nipple eczema(n=2). The patients were 34-62 (mean 52)years old. Invasive ductal carcinoma(n=13), DCIS(ductal carcinoma in situ, n-12), Paget's disease (n=2), and LCIS(lobular carcinoma in situ, n=1) were found during surgery. Six of 28 lesions(21%) showed evidence of axillary nodal metastasis;the majority arose from the upper outer quadrant of the breast (n=21). The mammographic findings were mass (50%), (and mass with microcalcification, 11%); microcalcification(29%); asymmetrical density(14%); and normal (7%). According to the mammographic density of breast parenchyma, the major finding in the low density group(N1+P1) was mass(9/9), and in the high density group(P2+DY) was microcalcification (12/19). Conclusion : The most common mammographic findings of nonpalpable breast cancer were mass (50%) and microcalcification(29%). Its features varied according to the mammographic density of breast parenchyma;mass was the main finding in the low density group and microcalcification in the high density group.

We retrospectively analyzed the mammographic, clinical and pathologic features of 25 patients (28 lesions) whose mammograms we obtained. Results : Among these 25 patients (28 lesions) screening was abnormal in 22; other symptoms were bloody nipple discharge(n=4), and nipple eczema(n=2). The patients were 34-62 (mean 52)years old. Invasive ductal carcinoma(n=13), DCIS(ductal carcinoma in situ, n-12), Paget's disease (n=2), and LCIS(lobular carcinoma in situ, n=1) were found during surgery. Six of 28 lesions(21%) showed evidence of axillary nodal metastasis;the majority arose from the upper outer quadrant of the breast (n=21). The mammographic findings were mass (50%), (and mass with microcalcification, 11%); microcalcification(29%); asymmetrical density(14%); and normal (7%). According to the mammographic density of breast parenchyma, the major finding in the low density group(N1+P1) was mass(9/9), and in the high density group(P2+DY) was microcalcification (12/19). Conclusion : The most common mammographic findings of nonpalpable breast cancer were mass (50%) and microcalcification(29%). Its features varied according to the mammographic density of breast parenchyma;mass was the main finding in the low density group and microcalcification in the high density group

    To demonstrate MR findings of cerebral palsy (CP), correlation with clinical findings, and differences between the full-term and pre-term group. Brain MRI of 94 patients with cerebral palsy (CP) were reviewed. The frequency of each MR finding, statistical correlation with clinical findings including type, severity and extent of CP, and differences between the full-term and pre-term group were analyzed. Abnormal MR findings were found in 83 patients(88%), and were as follows : diffuse brain atrophy(30%); periventricular leukomalacia(PVL)(28%); infarction(11%), basal ganglia abnormality(11%); delayed myelination(10%); nonspecific tissue loss or encephalomalacia(9%); and cortical dysplasia(7%). Hemiplegia was the most common condition among patients with infarction, and was found in 80% of this group; diplegia was found in 50% of cases with diffuse brain atrophy, while paraplegia was found in 36% of those with normal MR findings (p < .05). Mild symptoms were dominant in patients with normal MR findings(82%) and in those with infarctions(90%)(p < .05). PVL was the dominant finding in the pre-term group (65%) whereas findings in the full-term group varied; in this group, 38% of MR findings suggested prenatal insults. Possible causative factors were found in 66% of the full-term and 80% of the pre-term group. Perinatal factors were dominant in the pre-term group(81%), whereas prenatal and postnatal factors showed relatively higher frequencies in the full-term group(30% and 24%, respectively). Diffuse brain atrophy and PVL were the most common MR findings. The extent of CP the pre-term correlated well with MR findings. PVL and perinatal factors were dominant in the pre-term group, whereas variable MR findings and relatively higher frequencies of pre- and postnatal factors were found in the full-term group.

    We assess the utility of CT in the diagnosis of the sped of and complications associated with cholesteatomas of middle ear. We review retrospectively the CT studies of 116 patients who underwent surgical treatment after a preoperative diagnosis of cholesteatoma between 1988 and 1992. We compare the findings at CT and surgery, taking into account the site, extension, complications and noteworthly surgical aspects. In our study, CT disclosed the presence of a mass within the tympanic cavity in all cases (100%). Among the entire study population, there were 103 cases of cholesteatoma and 13 of chronic otitis media (COM). CT revealed signs compatible with cholesteatoma in 99 cases, 3 of which were classified as COM and 14 in which it was impossible to distinguish between COM and cholesteatoma. CT discolsed a high correlation coefficient for the detection of erosion of the ossicular chain (sensitivity, 94.4%; specificity, 63.6%) and a moderate coefficient for fistula in lateral semicircular canal (75.0% and 97.0%), rupture of the tegmen tympani (76.9% and 96.1%) and dehiscence of the osseous portion of the facial nerve canal (66.6% and 95.6%). In our experience, wich coincides with reports in the literature, we conclude that CT is currebtly an excellent imaging method for the presurgical assessment of cholesteatoma. Additional explorations are usually unneccessary. 12 refs

    We aim to investigate the clinical onset, computed tomography (CT) and magnetic resonance (MR) imaging findings, and follow-up of patients with cerebral amyloid angiopathy (CAA)-related inflammation, an uncommon but clinically striking presentation of CAA. We retrospectively reviewed the clinical manifestations, CT/MR imaging findings, and outcome of ten consecutive patients with CAA-related inflammation. In each patient, a brain CT study was performed at hospital admission, and brain MR imaging was carried out 2 to 4 days later. Clinical and radiologic follow-up findings were evaluated in all patients. The most common clinical onset was rapidly progressive cognitive decline, followed by focal neurological signs. Brain CT/MR showed unenhanced expansive subcortical lesions, corresponding to areas of vasogenic edema, associated with chronic lobar, cortical, or cortical-subcortical micro/macrohemorrhages. Clinical symptoms recovered in a few weeks under treatment in eight patients and spontaneously in the remaining two. MRI follow-up at 2 to 12 months after treatment showed resolution of the lesions. Three patients experienced symptomatic disease recurrence, with new lesions on CT/MR. In the absence of histological data, early recognition of the clinical symptoms and typical radiologic features of CAA-related inflammation is essential to enable timely establishment of proper treatment.

    Objective. To report and describe the MR imaging features of eight new cases of this rare soft tissue sarcoma and correlate them with the clinical and histologic findings.Design and patients. Retrospective analysis was carried out for the MR imaging characteristics and histologic findings of eight patients with pathologically proven epithelioid sarcoma and the literature was reviewed. Findings were correlated in each case with the patient's clinical presentation and eventual outcome.Results. The patients, whose primary tumors ranged from 2.5 cm to 19 cm in maximum dimension, were 1 to 90 years of age. Tumors involved the extremities (n=5), the scalp (n=2) and the paraspinal muscles (n=1). Five tumors presented as well-defined, frequently painful, deeply situated masses and three as subcutaneous nodules or cutaneous ulcers with no palpable mass. Four patients had associated regional lymphadenopathy and one had distant metastases at diagnosis. MR imaging showed tumor infiltration of adjacent tissues in seven patients. Signal characteristics reflected varying degrees of cellularity, and the presence of necrosis, hemorrhage, fibrosis, hyalinization and inflammation. Bone marrow involvement was demonstrated in one patient. Clinical outcomes were generally poor.Conclusions. Epithelioid sarcoma is an aggressive soft tissue sarcoma with a varied clinical presentation, growth pattern, MR signal characteristics and histologic picture. The tumor favors the distal extremities and is commonly infiltrative and accompanied by enlarged regional lymph nodes. This neoplasm may present as an intramuscular mass but should also be suspected in patients with ulcerating cutaneous nodules with or without regional lymphadenopathy. (orig.)

    The present study was conducted to investigate the relationship between magnetic resonance imaging (MRI) of the temporomandibular joint (TMJ) and clinical findings of patients having symptoms of temporomandibular disorders, and to consider the possibility to grasp the internal derangement of the TMJ from clinical findings. Subjects were 80 patients who visited to ask orthodontic treatment 16 males and 64 females. The average age was 22 years and 4 months. We performed a investigation of both their previous and present illness. In addition, to decide the correct condition concerning the internal derangement of the TMJ, patients were given MRI examinations (G. E. medical system Signa 1.5 Tesla) before orthodontic treatment. Results were as follows: The three symptoms of temporomandibular disorders-noise, pain, and abnormal mandibular movement, were not related to constant disk displacement. It seemed difficult to infer and obtain the diagnosis of the condition of internal derangement of the TMJ only from clinical findings. In a dental clinics having no medical imaging instrument such as MRI, it was, however, considered that the following items will make it possible to define the condition of internal derangements of the TMJ from clinical findings. As to respects concerning clinical findings, it is necessary to consider the previous illness as well as present illness. TMJ noise indicates a higher relationship to the disk displacement in MRI findings. The temporomandibular joint with plural symptoms indicated a higher incidence of disk displacement examined by MR Imaging than that with a single symptom. (author)

    Objective: to establish a correlation between clinical features in a group of children with tomographic diagnosis of schizencephaly and clefts extent and localization. Materials and methods: retrospective study of dossiers from the archives of Neurology and Medical Genetics Services at Instituto Fernandes Figueira/FIOCRUZ and Hospital Municipal Jesus, Rio de Janeiro, RJ, Brazil, in the period between 2000 and 2003. The study included 16 patients, nine female and seven male, with tomographic diagnosis of schizencephaly investigated for clinical findings, psychomotor development, motor/cognitive deficits and epilepsy. Results: predominance of bilateral clefts in 10:16 patients, open-lip schizencephaly type in 23:27 patients, and small lips in 11:27 patients. As regards anomalies associated with schizencephaly, pellucid septum absence was the most frequent one (10:16 patients). As regards clinical findings, 15 patients presented with developmental delay and motor deficit, six patients with cognitive deficit and ten with epilepsy. In three patients, we observed discordant clinical findings and cleft sizes, although the clefts were small, the clinical features severity was high because of other cerebral anomalies. Conclusion: the clinical features of schizencephaly are related to the size of the clefts, regardless laterality, presenting higher severity when associated with other cerebral anomalies. (author)

    Aim: To describe the imaging findings of jejunal diverticulitis as depicted at contrast-enhanced computed tomography (CT) and review the differential diagnosis and clinical management. Materials and Methods: CT and pathology databases were searched for the diagnosis of jejunal diverticulitis. Three cases were identified and the imaging and clinical findings correlated. Results: Jejunal diverticulitis presents as a focal inflammatory mass involving the proximal small bowel. A trial of medical management with antibiotics may be attempted. Surgical resection may be required if medical management is unsuccessful. Conclusion: The imaging findings at MDCT may allow a specific diagnosis of jejunal diverticulitis to be considered and may affect the clinical management of the patient

    The purpose of this study is to evaluate the CT findings and clinical features of patients with pneumatosis intestinalis. From January 2001 to October 2007, 15 patients with pneumatosis intestinalis were diagnosed by the use of CT. We analyzed the clinical features and CT findings to assess the involvement site, the presence of portal and mesenteric vein gas, and the existence of accompanied ischemic change. Of the 15 patients, five patients had end stage renal disease (33.3%), two patients underwent a gastrectomy, one patient underwent a laminectomy, one patient had tuberculous enteritis, one patient had lung cancer and one patient had pneumonia. Four patients presented with no specific disease. There was portal or mesenteric venous gas in six cases, and strangulation or an ischemic change of the bowel in five cases. Otherwise, pneumatosis intestinalis was associated with hydropneumoperitoneum in two cases, pneumoperitoneum in one case and a single case of perforated appendicitis. Nine patients underwent surgery for ischemic change of the bowel, pneumoperitoneum, appendicitis, and a clinical sign of panperitonitis. Among the remaining six patients, three patients recovered and were discharged, and three patients expired during progression of the disease. End stage renal disease is the most common condition associated with pneumatosis intestinalis. The presence of portomesenteric venous gas, ischemic change of the bowel, and linear pneumatosis intestinalis are indicative of a poor prognosis.

    2002-01-01

    Objective: To determine the relationship between the magnetic resonance (MR) appearance of the acromioclavicular (AC) joint and the physical findings. Design: A total of 116 consecutive patients underwent routine MR imaging (MRI) of the shoulder over an 18-month period. All MR studies were interpreted by a blinded, experienced musculoskeletal radiologist. Eleven variables were studied: the presence of osteophytes; fluid in the joint; fluid outside the joint; high signal in the clavicle or in the acromion; fluid in the subacromial bursa; irregularity of the joint margins; bulging of the capsule; widening of the joint; the age of the patient; and the presence of a rotator cuff tear. The clinical information was supplied by an experienced shoulder surgeon blinded to the MRI findings. A control group of 23 normal volunteers was also studied. Results: The only statistically significant correlation (P=0.0249) was between high signal in the distal clavicle and degenerative changes found clinically. A weaker relationship existed between fluid in the joint and the clinical examination and between increasing degenerative changes and advancing age. Otherwise, no material relationship was found between any of the other MR abnormalities and the clinical picture. Conclusion: There appears to be no real correlation between the MR appearances and the clinical findings in the AC joint. (orig.)

    This study analyses clinical data, EEC and X-ray findings of 102 stationary examined migraine patients, 62 of whom suffered from migraine accompagnee. Sex distribution, age at onset of disease, hereditary disease disposition and EEC findings largely correspond to the data given in literature. As it had been expected, the X-ray images of the skull and the cerebral angiographies performed in 46 patients suffering from migraine accompagnee did not show any pathological findings. The X-ray images were compared with those taken of patients without migraine anamnesis in order to detect non-pathologic variations. Neither differences in the intensity of vascular and diplovenous marking could be found in the native images of the skull nor any variations of the circle of Willisi. The dependency of the posterior cerebral artery on the carotid circulation existing in 41% of the migraine accompagnee does not lead to any particular alteration of the accompanying symptoms and signs. The idea is discussed to divide the migraine syndrome into simple, focal and complicated migraine on the basis of a uniform pathogenesis. (orig./MG) [de

  6. Clinical decision-making and secondary findings in systems medicine.

    2016-05-21

    Systems medicine is the name for an assemblage of scientific strategies and practices that include bioinformatics approaches to human biology (especially systems biology); "big data" statistical analysis; and medical informatics tools. Whereas personalized and precision medicine involve similar analytical methods applied to genomic and medical record data, systems medicine draws on these as well as other sources of data. Given this distinction, the clinical translation of systems medicine poses a number of important ethical and epistemological challenges for researchers working to generate systems medicine knowledge and clinicians working to apply it. This article focuses on three key challenges: First, we will discuss the conflicts in decision-making that can arise when healthcare providers committed to principles of experimental medicine or evidence-based medicine encounter individualized recommendations derived from computer algorithms. We will explore in particular whether controlled experiments, such as comparative effectiveness trials, should mediate the translation of systems medicine, or if instead individualized findings generated through "big data" approaches can be applied directly in clinical decision-making. Second, we will examine the case of the Riyadh Intensive Care Program Mortality Prediction Algorithm, pejoratively referred to as the "death computer," to demonstrate the ethical challenges that can arise when big-data-driven scoring systems are applied in clinical contexts. We argue that the uncritical use of predictive clinical algorithms, including those envisioned for systems medicine, challenge basic understandings of the doctor-patient relationship. Third, we will build on the recent discourse on secondary findings in genomics and imaging to draw attention to the important implications of secondary findings derived from the joint analysis of data from diverse sources, including data recorded by patients in an attempt to realize their

    OBJECTIVE To characterize clinical and laboratory findings in cats with naturally occurring sepsis, emphasizing hemostasis-related findings, and evaluate these variables for associations with patient outcomes. DESIGN Prospective, observational, clinical study. ANIMALS 31 cats with sepsis and 33 healthy control cats. PROCEDURES Data collected included history; clinical signs; results of hematologic, serum biochemical, and hemostatic tests; diagnosis; and outcome (survival vs death during hospitalization or ≤ 30 days after hospital discharge). Differences between cats with and without sepsis and associations between variables of interest and death were analyzed statistically. RESULTS The sepsis group included cats with pyothorax (n = 10), septic peritonitis (7), panleukopenia virus infection (5), bite wounds (5), abscesses and diffuse cellulitis (3), and pyometra (1). Common clinical abnormalities included dehydration (21 cats), lethargy (21), anorexia (18), pale mucous membranes (15), and dullness (15). Numerous clinicopathologic abnormalities were identified in cats with sepsis; novel findings included metarubricytosis, hypertriglyceridemia, and high circulating muscle enzyme activities. Median activated partial thromboplastin time and plasma D-dimer concentrations were significantly higher, and total protein C and antithrombin activities were significantly lower, in the sepsis group than in healthy control cats. Disseminated intravascular coagulopathy was uncommon (4/22 [18%] cats with sepsis). None of the clinicopathologic abnormalities were significantly associated with death on multivariate analysis. CONCLUSIONS AND CLINICAL RELEVANCE Cats with sepsis had multiple hematologic, biochemical, and hemostatic abnormalities on hospital admission, including several findings suggestive of hemostatic derangement. Additional research including larger numbers of cats is needed to further investigate these findings and explore associations with outcome.

    Objective: To assess clinically relevant MRI findings in the shoulders of symptomatic and asymptomatic elite swimmers. Method: Twenty (aged 16–23 years elite swimmers completed questionnaires on their swimming training, pain and shoulder function. MRI of both shoulders (n = 40 were performed and all swimmers were given a standardised clinical shoulder examination. Results: Both shoulders of 11 male and 9 female elite swimmers (n = 40 were examined. Eleven of the 40 shoulders were clinically symptomatic and 29 were asymptomatic. The most common clinical finding in both the symptomatic and asymptomatic shoulders was impingement during internal rotation, with impingement in 54.5% of the symptomatic shoulders and in 31.0% of the asymptomatic shoulders. The most common MRI findings in the symptomatic and asymptomatic shoulders were supraspinatus tendinosis (45.5% vs. 20.7%, subacromial subdeltoid fluid (45.5% vs. 34.5%, increased signal in the AC Joint (45.5% vs. 37.9% and AC joint arthrosis (36.4% vs. 34.5%. Thirty-nine (97.5% of the shoulders showed abnormal MRI features. Conclusion: MRI findings in the symptomatic and asymptomatic shoulders of young elite swimmers are similar and care should be taken when reporting shoulder MRIs in these athletes. Asymptomatic shoulders demonstrate manifold MRI abnormalities that may be radiologically significant but appear not to be clinically significant.

    Highlights: • CT cervico-cerebral angiography (CTCCA) is a commonly performed study for assessment of vascular pathologies of head and neck. • This study assessed the prevalence, clinical significance and management of extravascular incidental findings detected on CTCCA. • This study demonstrated the presence of clinically significant incidental findings in 14% of patients undergoing CTCCA with 8% of these findings deemed to be highly significant. 19% of patients with highly clinically significant findings did not receive appropriate follow up. • A standardised method of reporting incidental findings, such as that used in this paper is suggested to aid radiologists and referring physicians in recording and communicating these findings. - Abstract: Introduction: CT cervico-cerebral angiography (CTCCA) is now the first line diagnostic imaging modality for the majority of vascular pathologies of the head and neck with diagnostic value comparable to or better than traditional angiographic techniques. The aim of this study was to assess the prevalence, clinical significance and management of extravascular incidental findings detected on CTCCA. Materials and methods: A retrospective review of the CTCCA reports of 302 consecutive patients from 2009 to 2013 was undertaken. Extravascular incidental findings were classified, according to an adaptation of the CT colonography data and reporting system (CRADS), as EV1–EV4. EV1 = no incidental findings, EV2 = clinically insignificant incidental finding, EV3 = incidental finding of intermediate clinical significance, EV4 = highly clinically significant finding. Follow up of the electronic medical records of patients with EV3 or EV4 findings was undertaken to determine subsequent management. Results: Potentially clinically significant findings were demonstrated in 14.2% of patients with 8.6% of patients having a highly clinically significant finding. 4 incidental findings were confirmed to be malignant lesions and 5

    Full Text Available Abstract Objectives The aim of the study was to determine if differences in clinical diagnosis versus autopsy findings concerning the cause of death in polytrauma fatalities would be detected in 19 cases of fatal polytrauma from a Level 1 trauma centre. Methods Clinical diagnoses determining the cause of death in 19 cases of fatal polytrauma (2007 - 2008 from a Level 1 trauma centre were correlated with autopsy findings. Results In 13 cases (68%, the clinical cause of death and the cause of death as determined by autopsy were congruent. Marginal differences occurred in three (16% patients while obvious differences in interpreting the cause of death were found in another three (16% cases. Five fatalities (three with obvious differences and two with marginal differences were remarked as early death (1-4 h after trauma and one fatality with marginal differences as late death (>1 week after trauma. Obvious and marginal discrepancies mostly occurred in the early phase of treatment, especially when severely injured patients were admitted to the emergency room undergoing continued cardiopulmonary resuscitation, i. e. limiting diagnostic procedures, and thus the clinical cause of death was essentially determined by basic emergency diagnostics. Conclusions Autopsy as golden standard to define the cause of death in fatal polytrauma varies from the clinical point of view, depending on the patient's pre-existing condition, mechanism of polytrauma, necessity of traumatic cardiopulmonary resuscitation, survival time, and thus the possibility to perform emergency diagnostics. An autopsy should be performed at least in cases of early fatal polytrauma to help establishing the definite cause of death. Moreover, autopsy data should be included in trauma registries as a quality assessment tool.

    Since the introduction of the CT scanner, the present authors have experienced 111 cases of lacunar infarction which were diagnosed on the basis of clinical manifestations and/or CT findings, being 35 % of total 318 cases of acute cerebral infarction in our series. The clinical features and their correlation with the CT findings were studied in the cases of lacunar infarction. The results were as follows. 1) Seventy-four per cent of the patients were hypertensive. 2) Fifty per cent of the patients had only motor deficit. 3) The patients who revealed small deep infarctions in the posterior two-thirds of the posterior limb of the internal capsule on CT scan had more marked motor impariment with more involvement of the upper extremity than the lower extremity. 4) The recovery of the motor deficit was generally good, but unsatisfactory when the patient had a larger lesion than 10 mm in diameter.

    CT and MR findings of nine cases with intra temporal facial nerve neuromas were described and compared with CT findings of 3 cases with facial nerve palsy and facial nerve canal erosion which may mimic facial nerve neuroma. The tympanic segment of the facial nerve was involved in 8 cases, mastoid segment in 7 cases and labyrinthine segment in 5 cases. The lesions were easily diagnosed with high resolution CT with bone algorithms by showing the expansion of bony structures along the course of the facial nerves. In 4 cases with large vertical segment tumors, extensive destruction of mastoid air cells and external auditory canals posed difficulty in making a diagnosis. Two out of 5 cases with labyrinthine segment involvement were presented as middle cranial fossa masses. MRI with enhancement was performed in 4 cases and was useful in characterizing the lesion as a tumor with its superior sensitivity to enhancement. Three cases of facial neuroma-mimicking lesion including post-inflammatory peri neural thickening, peri neural extension from parotid adenoid cystic carcinoma, and congenita; cholesteatoma showed irregular erosion or mild expansion of the facial nerve canal which may be helpful for differential diagnosis from neuromas.

    Full Text Available This study aims to investigate clinical and pathological findings of a clinical Coenurus cerebralis case in a 10-month-old Simmental male calf. Clinical examination of the calf revealed incoordination, irregular gait, failure to hold the head straight, leftward head tilt, and circling. The animal was diagnosed with C. cerebralis and euthanazia was recommended. The autopsy demonstrated a cyst (9x7 cm in the caudal of the left cerebral hemisphere within the cranium. The cyst caused compression over the ventral portion of the left cerebral hemisphere, while a marked perforation of 3-4 cm diameter was found on the sphenoid bone. Histopathologically, hyperemia and perivascular mononuclear cell infiltration were observed. In conclusion, we found it beneficial to present the clinical and pathological findings of this calf infected with C. cerebralis which is known to be a rare clinical entity among cattle.

    AIM: A rapid assessment stroke clinic (RASC) was established to provide a rapid diagnostic service to individuals with suspected transient cerebral or ocular ischaemia or recovered non-hospitalized strokes. In this report we review imaging findings and clinical outcomes of patients proceeding to the carotid surgery programme. METHODS: Between October 2000 and December 2002, 1339 people attended the RASC. The findings of head CT and carotid Doppler ultrasound of the 1320 patients who underwent brain and carotid imaging were reviewed, and the number subsequently proceeding to carotid angiography and intervention was reported. RESULTS: CT head scans were normal in 57% of cases; 38% demonstrated ischaemia or infarction; and 3% yielded incidental or other significant findings not related to ischaemia. On screening with carotid Doppler ultrasound, 7.5% showed greater than 50% stenosis on the symptomatic side. A total of 83 patients (6.2%) proceeded to cerebral angiography and 65 (4.8%) underwent carotid endarterectomy or endovascular repair. CONCLUSION: Rapid-access neurovascular clinics are efficient in selecting patients for carotid intervention, but this is at a cost and the number of potential strokes prevented is small. Alternative management pathways based on immediate medical treatment need to be evaluated

    Objective: The aim of this retrospective study was to report the clinical features and MR imaging findings of patients with brucellar spondylodiscitis. Materials and methods: Twenty-two patients with spondylodiscitis, recruited among 152 patients with brucellosis referred from the Department of Infectious Diseases. Patients were diagnosed based on positive clinical findings, ≥1/160 titers of brucella agglutination tests and/or positive blood cultures. Magnetic resonance imaging (MRI) was performed to all of the patients with spondylodiscitis. Signal changes and enhancement of vertebral bodies, involvement of paravertebral soft tissues and epidural spaces, nerve root and cord compression and abscess formation were assessed. Results: All of the patients (n = 22; 7 F, 15 M) had ≥1/160 titers of brucella agglutination test and blood culture was positive in 9. A great majority of the patients had involvement at only one vertebrae level (n = 21, 95.5%), whereas one patient (4.5%) had multilevel involvement. In MRI, eight patients had soft tissue involvement and three had abscess formation. All cases had vertebral and discal enhancement. Additionally epidural extension was detected in four cases, posterior longitudinal ligament (PLL) elevation in five cases and root compression in two cases. Conclusion: Brucella is still a public health problem in endemic areas. MRI is a highly sensitive and non-invasive imaging technique which should be first choice of imaging in the early diagnosis of spondylodiscitis

    This study evaluated the relationship between 111 In-labeled leukocyte scintigraphy and clinical information and laboratory findings in 24 patients with bone infection and 35 patients with abdominal infection. Fifty-nine scintigrams were retrospectively reviewed and classified into positive or negative results. As the laboratory findings, C-reactive protein (CRP) level, erythrocyte sedimentation rate (ESR) at 60 minutes, and peripheral blood leukocyte counts (WBCC) were evaluated. Clinical information such as presence of fever and administration of antibiotics was also compared. No significant relationship between the scintigraphic results and clinical as well as laboratory findings was observed in bone infection patients. CRP levels in positive scintigraphic patients were significantly higher than those in negative scintigraphic patients in the abdominal infection group, otherwise the other indices were not correlated with the scintigraphic results. A few patients with slightly increased CRP (mostly chronic cases) did not show positive scintigrams, suggesting an increased false negative rate of leukocyte scintigraphy in such circumstances. These results suggest that it is inappropriate to determine the application of leukocyte scintigraphy depending on clinical as well as laboratory findings, and leukocyte scintigraphy would yield additional information different from other indices when evaluating inflammatory foci.

    Full Text Available Turner Syndrome is a genetic condition in females that results from an abnormal chromosome. One of the X chromosomes is missing or misshapen in the most cells of the body. Three classics clinical symptoms of the syndrome are: incomplete sexual maturation, short stature and pterygium colli. Turner Syndrome is diagnosed by karyotyping. In the retrospective study for a twelve years period (1991-2002 correlation between clinical and cytogenetics findings was established in our Center among 47 examinees from all parts of Federation of Bosnia and Herzegovina, who had suspect clinical diagnosis of Turner Syndrome. The syndrome was demonstrated by cytogeneticsexaminations in 30(63,8% examinees and excluded in 17 (36,2% examinees. The most frequent karyotype is monosomy of X chromosome (45,X found at 63,3%, than isochromosome of Xq (46,XisoXq found at 16,7%, mosaic form (46,XX/45,X and deletion of Xp (46,XdelXp both at 6,7%, than deletion of Xq (46,XdelXq and ring of Xp (46,XX/46,XringXp both at 3,3%. Our results suggest that promptly and exactly diagnosis of Turner syndrome is very important due to introducing growth hormone therapy and estrogen therapy at a very young age.

    To investigate the association between psoriatic arthritis (PsA)-specific clinical composite scores and ultrasound-verified pathology as well as comparison of clinical and ultrasound definitions of remission. We performed a prospective study on 70 consecutive PsA patients. Clinical assessments included components of Disease Activity Index for Psoriatic Arthritis (DAPSA) and the Composite Psoriatic Disease Activity Index (CPDAI). Minimal disease activity (MDA) and the following remission criteria were applied: CPDAI joint, entheses and dactylitis domains (CPDAI-JED)=0, DAPSA≤3.3, Boolean's remission definition and physician-judged remission (rem-phys). B-mode and power Doppler (PD-) ultrasound findings were semiquantitatively scored at 68 joints (evaluating synovia, peritendinous tissue, tendons and bony changes) and 14 entheses. Ultrasound remission and minimal ultrasound disease activity (MUDA) were defined as PD-score=0 and PD-score ≤1, respectively, at joints, peritendinous tissue, tendons and entheses. DAPSA but not CPDAI correlated with B-mode and PD-synovitis. Ultrasound signs of enthesitis, dactylitis, tenosynovitis and perisynovitis were not linked with clinical composites. Clinical remission or MDA was observed in 15.7% to 47.1% of PsA patients. Ultrasound remission and MUDA were present in 4.3% and 20.0% of patients, respectively. Joint and tendon-related PD-scores were higher in patients with active versus inactive disease according to CPDAI-JED, DAPSA, Boolean's and rem-phys, whereas no difference was observed regarding enthesitis and perisynovitis. DAPSA≤3.3 (OR 3.9, p=0.049) and Boolean's definition (OR 4.6, p=0.03) were more useful to predict MUDA than other remission criteria. PsA-specific composite scores partially reflect ultrasound findings. DAPSA and Boolean's remission definitions better identify MUDA patients than other clinical criteria.

    CT-scanning of 96 temporal bones was carried out to reveal the extension of cholesteatoma, periossicular drainage, fracture lines, enlarged internal acoustic meatus and anomalies of labyrinthine capsules and ossicles. The clinical aspects of CT-scanning of the temporal bone (CTTB) were as follows: 1) Inner ear anomalies were observed in 17 temporal bones of unilateral deafness, high tone loss from unknown origin and fluctuant hearing loss. CTTB may explain the pathology of deafness from unknown origin. 2) Inner ear anomalies may be classified into more detailed groups than before. 3) The extension of cholesteatoma, localization and size of labyrinthine fistula can be estimated prior to surgery. 4) Cholesteatoma in a mastoidectomy cavity may be detected. 5) The malleus and incus may be visualized, although the stapes can hardly be found. 6) Fracture lines of a temporal bone, destruction of the internal acoustic meatus may be clearly detected.

    Full Text Available This article characterizes the opinions of patients and family members of patients undergoing clinical genomic-based testing regarding the return of incidental findings from these tests. Over sixteen months, we conducted 55 in-depth interviews with individuals to explore their preferences regarding which types of results they would like returned to them. Responses indicate a diversity of attitudes toward the return of incidental findings and a diversity of justifications for those attitudes. The majority of participants also described an imperative to include the patient in deciding which results to return rather than having universal, predetermined rules governing results disclosure. The results demonstrate the importance of a patient centered-approach to returning incidental findings.

    Full Text Available Congenital simple hamartoma of retinal pigment epithelium (CSHRPE is a rare, asymptomatic, and incidentally detected benign lesion. However, it is very important to do the differential diagnosis from other pigmented retinal lesions. Its clinical presentation and imaging findings are very helpful in doing this differentiation. This paper presents clinical and imaging findings of a 56-year-old woman with incidentally detected CSHRPE. The lesion was small, heavily pigmented, well circumscribed, and slightly elevated. Optical coherence tomography (OCT scanning was diagnostic and showed an elevated retina at the site of the lesion, increased optical reflectivity on its inner surface, optical shadowing of deeper structures, and clearly cut tumor margins. Ocular ultrasonography, fluorescein angiography, and fundus autofluorescence imaging which is firstly described in this report did not show any characteristic finding.

    The clinician's major role in management of the dizzy patient involves determining what dizziness is vertigo, and what vertigo is of central or peripheral origin. These demand attention to details of history, otolaryngological workup including vestibular assessment, and often use of diagnostic and management algorithms. There is paucity of published reports of the management outcomes of peripheral vestibular diseases from Africa. Two tertiary care otologist-led dedicated vertigo clinics are located in Abuja, Nigeria. A prospective, non-randomized study of patients presenting with features of peripheral vestibular diseases attending the National Hospital Abuja Nigeria (between May 2005 and April 2014) and CSR Otologics Specialist Clinics (May 2010 to April 2014) was carried out. Both institutions adopted the same diagnostic and management protocols. Data extracted from anonymized databases created for this study include age, sex, vertigo duration (acute 12 weeks), dizziness handicap inventory score at presentation and at subsequent visits, otological and vestibular findings, ice-water caloric testing results, other investigation outcomes, treatments offered and outcomes. 561/575 (97.5 %) of the cases recorded had peripheral vestibular disease. The male-to-female ratio was 290:271. The mean age of the subjects was 44.7 years. Duration of vertigo at presentation was acute in 278 subjects and chronic in 283 subjects. Identifiable clinical diagnostic groups include BPPV (n = 200), Meniere's disease (n = 189), cervicogenic vertigo (n = 35), labyrinthitis (n = 32), Migraine-associated vertigo (MAV) (n = 32), cholesteatoma/perilymph Fistula (n = 10), climacteric vertigo (n = 8) and unclassified vertigo (n = 55). Migraine-associated vertigo recorded the highest DHI score (95 % CI 75 ± 4.3), followed by cholesteatoma/perilymph fistula (95 % CI 72 ± 6.1) and labyrinthitis (95 % CI 62 ± 1.9).

    To evaluate the clinical usefulness of radionuclide(RI) cisternography in patients with hydrocephalus, we retrospectively analyzed RI cisternographic findings of 47 patients by using our classification which was modified from Baum's and correlated them with CT(n=37) or MRI(n=10) findings and clinical outcome in selected patients with hydrocephalus(n=37). Modified RI cisternography patterns of 37 patients were type I in three case(8%), type II in seven(18%), type III-A in six(16%), no case of type III-B, type IV-A in 12(32%), and type IV-B in nine(24%). Ri cisternography enabled to differentiate communicating hydrocephalus(27 cases, 73%) from noncommunicating hydrocephalus(10 case, 27%). There was marked clinical improvement in 17 patients(46%), slight improvement in 11 patients(30%), and no improvement in nine patients(24%). The clinical outcome of patients with RI cisternographic type IV-B was worse than that of other types. CT and MRI could neither predict the clinical outcome nor differentiate type IV-B from type IV-A(P>0.05). Ventricular size index(VSI)was significantly higher in patients with type IV than that with other type(p<0.001). RI cisternographic patterns of communicating hydrocephalous were relatively correlated with clinical outcome(r=-0.53, p=.0010 . VIS(r=0.59, p=.001), and dilation of fourth ventricle(r=0.41, p<0.05). We suggest that our modified classification of RI cisternographic patterns can provide more strict physiological assessment of the CFS dynamics and RI cisternography may be still useful to differentiate communicating hydrocephalus from noncommunicating hydrocephalus and to predict the clinical outcome in conjunction with CT/ MR findings and clinical presentation

    2016-01-01

    This brief communication introduced a systematic way to find a professional audiology clinic developed for patients and professionals by the American Academy of Audiology, American Speech-Language-Hearing Association, and Healthy Hearing. Patients can access each organization's website to find professionals and/or clinics based on criteria such as location, hours, special areas, types of service, reviews and rating by previous patients, and kinds of insurance accepted. Such a system may protect the patients from information overload, guarantee accurate information, and help them find themselves professional audiologists who can assist them. We expect professional organizations to adopt this system as soon as possible and link hearing-impaired patients with professional audiologists in Korea. PMID:27626086

    Background. The Schatzki ring is a well-known clinical and radiologic entity in adults, but is thought to be rare in childhood. Objective. To review the clinical presentations and radiologic findings of children and young adults with Schatzki rings. Materials and methods. A retrospective review of all barium swallow examinations done between 1990 and 1996 revealed 20 patients with Schatzki rings. Results. The most frequent presenting symptoms of these patients were progressive dysphagia with solid food and acute food impaction. Radiographic findings of Schatzki rings were typical in all cases. Twelve patients had endoscopy and all had evidence of esophagitis. Conclusion. Schatzki rings are not rare in childhood. The patients are symptomatic, presenting with either progressive dysphagia with solids or acute food impaction. A thorough evaluation of the distal esophagus should be performed in patients with a suggestive clinical history. (orig.) With 2 figs., 8 refs.

    Objective Posterior reversible encephalopathy syndrome (PRES) is characterized by typical radiologic findings in the posterior regions of the cerebral hemispheres and cerebellum. The symptoms include headache, nausea, vomiting, visual disturbances, focal neurologic deficits, and seizures. The aim of this study is to evaluate the clinical and radiological features of PRES in children and to emphasize the recognition of atypical features. Materials & Methods We retrospectively examined 23 children with PRES from Mar 2010-Apr 2015 in Inonu University Turgut Ozal Medical Center in Turkey. We compared the clinical features and cranial MRI findings between underlying diseases of PRES. Results The most common precipitating factors were hypertension (78.2%) and medications, namely immunosuppressive and antineoplastic agents (60.8%). Manifestations included mental changes (100%), seizures (95.6%), headache (60.8%), and visual disturbances (21.7%) of mean 3.6 (range 1-10) days' duration. Cranial magnetic resonance imaging (MRI) showed bilateral occipital lesions in all patients, associated in 82.6% with less typical distribution of lesions in frontal, temporal or parietal lobes, cerebellum, corpus callosum, basal ganglia, thalamus, and brain stem. Frontal involvement was predominant, observed in 56.5% of patients. Clinical recovery was followed by radiologic resolution in all patients. Conclusion PRES is often unsuspected by the clinician, thus radiologists may be the first to suggest this diagnosis on an MRI obtained for seizures or encephalopathy. Atypical MRI finding is seen quite often. Rapid diagnosis and treatment are required to avoid a devastating outcome. PMID:29379559

    Cognitive behavioural therapy (CBT) is beneficial in depression. Symptom scores can be translated into Clinical Global Impression (CGI) scale scores to indicate clinical relevance. We aimed to assess the clinical relevance of findings of randomised controlled trials (RCTs) of CBT in depression. We identified RCTs of CBT that used the Hamilton Rating Scale for Depression (HAMD). HAMD scores were translated into Clinical Global Impression - Change scale (CGI-I) scores to measure clinical relevance. One hundred and seventy datasets from 82 studies were included. The mean percentage HAMD change for treatment arms was 53.66%, and 29.81% for control arms, a statistically significant difference. Combined active therapies showed the biggest improvement on CGI-I score, followed by CBT alone. All active treatments had better than expected HAMD percentage reduction and CGI-I scores. CBT has a clinically relevant effect in depression, with a notional CGI-I score of 2.2, indicating a significant clinical response. The non-specific or placebo effect of being in a psychotherapy trial was a 29% reduction of HAMD. Copyright © 2017. Published by Elsevier Masson SAS.

    Objective: The purpose of our study was to describe the clinical features, imaging characteristics, pathologic findings and outcome of microinvasive ductal carcinoma in situ (DCISM). Materials and methods: The records of 21 women diagnosed with microinvasive ductal carcinoma in situ (DCISM) from November 1993 to September 2006 were retrospectively reviewed. The clinical presentation, imaging and histopathologic features, and clinical follow-up were reviewed. Results: The 21 lesions all occurred in women with a mean age of 56 years (range, 27-79 years). Clinical findings were present in ten (48%): 10 with palpable masses, four with associated nipple discharge. Mean lesion size was 21 mm (range, 9-65 mm). The lesion size in 62% was 15 mm or smaller. Mammographic findings were calcifications only in nine (43%) and an associated or other finding in nine (43%) [mass (n = 7), asymmetry (n = 1), architectural distortion (n = 1)]. Three lesions were mammographically occult. Sonographic findings available in 11 lesions showed a solid hypoechoic mass in 10 cases (eight irregular in shape, one round, one oval). One lesion was not seen on sonography. On histopathologic examination, all lesions were diagnosed as DCISM, with a focus of invasive carcinoma less than or equal to 1 mm in diameter within an area of DCIS. Sixteen (76%) lesions were high nuclear grade, four (19%) were intermediate and one was low grade (5%). Sixteen (76%) had the presence of necrosis. Positivity for ER and PR was noted in 75% and 38%. Nodal metastasis was present in one case with axillary lymph node dissection. Mean follow-up time for 16 women was 36 months without evidence of local or systemic recurrence. One patient developed a second primary in the contralateral breast 3 years later. Conclusion: The clinical presentation and radiologic appearance of a mass are commonly encountered in DCISM lesions (48% and 57%, respectively), irrespective of lesion size, mimicking findings seen in invasive carcinoma

    Three patients with localized polycystic kidney infections are presented with the pertinent clinical, laboratory, and radiographic findings. Gallium-67 citrate and angiography play an important role in evaluation of these patients. Angiography in particular is valuable in the diagnosis and the exact localization of the inflammatory disease. Localization is extremely important in planning surgical treatment should conservative therapy fail

    Brucellosis is the most common zoonotic disease worldwide and remains an important human disease especially in developing countries. The aim of the present study was to evaluate clinical manifestations and laboratory findings of childhood brucellosis in Van province of Eastern Turkey. To our knowledge, this is the largest series of childhood brucellosis reported in the literature. In this retrospective study, 496 children with brucellosis were assessed for the clinical manifestations and laboratory findings from July 2009 through December 2013. The diagnosis of brucellosis was based on clinical findings and a standard tube agglutination test (titer ≥ 1:160). Data were analyzed using Minitab version 16. The study included 496 children (boys, 60.5%) with a mean age of 10.0 ± 3.95 years (range, 1-16 years). The most frequent clinical symptoms were arthralgia (46.2%), fever (32.1%), and abdominal pain (17.1%) and the most common clinical signs were peripheral arthritis (10.1%), splenomegaly (2.2%) and hepatomegaly (1.8%). The most contagious seasons were summer and autumn (63.3%). Elevated lactate dehydrogenase and C-reactive protein and erythrocyte sedimentation rate were reported in 63.1%, 58.7%, and 55.2% of the patients, respectively. Anemia (20.4%), thrombocytopenia (15.5%), and leukopenia (12.1%) were the most common hematologic findings. Brucellosis remains a serious public health problem in Turkey. The clinical and laboratory characteristics of childhood brucellosis have been described in order to assist clinicians in diagnosing and monitoring the disease. © 2015 Japan Pediatric Society.

    To determine the clinical correlation of magnetic resonance imaging (MRI) findings of temporomandibular joint internal derangements. The MR images of 150 TMJs in 75 patients were analyzed. The clinical symptoms were pain in the pre auricular area and masticatory muscles and TMJ sounds. There was a statistically significant relationship between the MRI diagnoses of different types of disc displacements and clinical findings of pain, clicking, and crepitus. The risk of TMJ pain was increased when the disc displacement without reduction occurred at the same time in combination with the osteoarthrosis and effusion. Regardless of the results, the data indicate that each of these MR imaging variables may not be regarded as the unique and dominant factor in defining TMJ pain occurrence.

The data obtained in large-scale clinical trials suggest that GLM has a good safety profile. The most common  adverse events (AE were infections, more often mild. The rate of infections was higher with the use of GLM 100 mg than with that of 50 mg. The overall cancer rate did not increase during a follow-up of less than 160 weeks. However, the rate of lymphomas in patients receiving GLM 100 mg proved to be higher than in those taking GLM 50 mg, in the general population, and in the placebo group in particular. AE were evenly distributed among patients with rheumatoid  arthritis, psoriatic arthritis, or ankylosing spondylitis. Overall, the findings are in agreement with the data on the safety of previously used TNF-α inhibitors. No fundamentally new AE have been encountered. It is necessary to accumulate  data on the use of GLM in real clinical practice, which will be able to more objectively define its place in the current therapy of rheumatic diseases.

    Early data from clinical studies suggest that intracoronary injection of autologous progenitor cells may beneficially affect postinfarction remodeling and perfusion. Beyond intracoronary infusion of autologous bone marrow mononuclear CD34+ cells (MNCCD34+), mobilization of stem cells by G-CSF has recently attracted attention because of various advantages such as the noninvasive nature of MNCCD34+ mobilization by subcutaneous injections. It is the aim of the present work to give an overview about the current experimental and clinical findings of G-CSF treatment in acute myocardial infarction.

    The diagnosis of subacromial pathology is limited by the poor accuracy of clinical tests for specific pathologies. The aim of this study was to estimate the diagnostic accuracy of clinical examination and imaging features for identifying subacromial pain (SAP) defined by a positive response to diagnostic injection, and to evaluate the influence of imaging findings on the clinical diagnosis of SAP. In a prospective, diagnostic accuracy design, 208 consecutive patients presenting to their primary healthcare practitioner for the first time with a new episode of shoulder pain were recruited. All participants underwent a standardized clinical examination, shoulder x-ray series and diagnostic ultrasound scan. Results were compared with the response to a diagnostic block of xylocaineTM injected into the SAB under ultrasound guidance using ≥80% post-injection reduction in pain intensity as the positive anaesthetic response (PAR) criterion. Diagnostic accuracy statistics were calculated for combinations of clinical and imaging variables demonstrating the highest likelihood of a PAR. A PAR was reported by 34% of participants. In participants with no loss of passive external rotation, combinations of three clinical variables (anterior shoulder pain, strain injury, absence of symptoms at end-range external rotation (in abduction)) demonstrated 100% specificity for a PAR when all three were positive (LR+ infinity; 95%CI 2.9, infinity). A full-thickness supraspinatus tear on ultrasound increased the likelihood of a PAR irrespective of age (specificity 98% (95%CI 94, 100); LR+ 6.2; 95% CI 1.5, 25.7)). Imaging did not improve the ability to rule-out a PAR. Combinations of clinical examination findings and a full-thickness supraspinatus tear on ultrasound scan can help confirm, but not exclude, the presence of subacromial pain. Other imaging findings were of limited value for diagnosing SAP.

    Full Text Available OBJECTIVES: Septic pulmonary embolism caused by a Klebsiella (K. pneumoniae liver abscess is rare but can cause considerable morbidity and mortality. However, clinical information regarding this condition is limited. This study was conducted to elucidate the full disease spectrum to improve its diagnosis and treatment. METHOD: We reviewed the clinical characteristics, imaging findings, and clinical courses of 14 patients diagnosed with septic pulmonary embolism caused by a K. pneumoniae liver abscess over a period of 9 years. RESULTS: The two most prevalent symptoms were fever and shortness of breath. Computed tomography findings included a feeding vessel sign (79%, nodules with or without cavities (79%, pleural effusions (71%, peripheral wedge-shaped opacities (64%, patchy ground-glass opacities (50%, air bronchograms within a nodule (36%, consolidations (21%, halo signs (14%, and lung abscesses (14%. Nine (64% of the patients developed severe complications and required intensive care. According to follow-up chest radiography, the infiltrates and consolidations were resolved within two weeks, and the nodular opacities were resolved within one month. Two (14% patients died of septic shock; one patient had metastatic meningitis, and the other had metastatic pericarditis. CONCLUSION: The clinical presentations ranged from insidious illness with fever and respiratory symptoms to respiratory failure and septic shock. A broad spectrum of imaging findings, ranging from nodules to multiple consolidations, was detected. Septic pulmonary embolism caused by a K. pneumoniae liver abscess combined with the metastatic infection of other vital organs confers a poor prognosis.

    Full Text Available Background. It is unclear whether history and physical examination findings can predict abnormalities on head computed tomography (CT believed to indicate increased risk of lumbar-puncture- (LP- induced brain herniation. The objectives of this study were to (1 identify head CT findings felt to be associated with increased risk of brain herniation and (2 to assess the ability of history and physical examination to predict those findings. Methods. Using a modified Delphi survey technique, an expert panel defined CT abnormalities felt to predict increased risk of LP-induced brain herniation. Presence of such findings on CT was compared with history and physical examination (H&P variables in 47 patients. Results. No H&P variable predicted “high-risk” CT; combining H&P variables to improve sensitivity led to extremely low specificity and still failed to identify all patients with high-risk CT. Conclusions. “High-risk” CT is not uncommon in patients with clinical characteristics known to predict an absence of actual risk from LP, and thus it may not be clinically relevant. “Overdiagnosis” will be increasingly problematic as technological advances identify increasingly subtle deviations from “normal.”

    The purpose of this study is to evaluate whether there is any correlation between the CT features of hemosiderosis and clinical findings in patients with chronic renal failure who have received multiple blood transfusion. Among chronic renal failure patients who had undergone long-tern dialysis and received multiple blood transfusions, CT findings in 16 cases in which increased liver attenuation was seen on images obtained for other purpose, were analyzed by three radiologic specialists. The attenuation values of liver, spleen and pancreas compared with that of back muscle were correlated with the amount and duration of transfusion, and blood ferritin level. There is no correlation between the CT features of hemosiderosis and clinical findings. In patients with chronic renal failure and no clinical symptoms, the status of iron overload was relatively easily detected on CT. Close observation of CT findings is thus thought to prevent significant permanent functional deformity of organs in patients with chronic renal failure who have received multiple blood transfusions.

    Objective: To analyze the clinical features and imaging findings of juvenile ankylosing spondylitis (JAS) in order to improve the diagnosis and the prognosis of JAS. Methods: Twelve cases were analyzed retrospectively and 14 cases, who were followed-up averagely for 2.3 years, were analyzed prospectively. Initially 10 were diagnosed as Still's disease and four were diagnosed as rheumatoid arthritis. Photography was performed in all cases, CT scan was done in 18 cases, and MRI in 8 cases. Lower extremity big joint disorders were observed in all cases and the small joints were reserved. The abnormalities of the sacroiliac joint were revealed in the early stage in 12 cases. The results were analyzed statistically. Results: The age of preliminary diagnosis was 9.3 years in average. There were statistical correlation between the age of the first episode and severity of the disease. And there were statistical correlation between the course of the illness and severity of the disease. The large joints of the lower extremities were most commonly involved. Conclusion: There were characteristic clinical features and imaging findings in the JAS. Early diagnosis and treatment improve the prognosis

    Published reports of rib fractures in adult cattle are limited to the occurrence of chronic rib swellings caused by calluses, which are unremarkable from a clinical standpoint, whereas studies identifying clinical signs of rib fractures were not found in a literature search. This report describes the clinical and postmortem findings in four cows with rib fractures. The 13th rib was fractured in three cows and the 11th rib in the remaining cow; three fractures were on the right and one on the left side. Clinical and postmortem findings varied considerably, and percussion of the rib cage elicited a pain response in only one cow. One cow had generalised peritonitis because of perforation of the rumen by the fractured rib. One cow was recumbent because of pain and became a downer cow, and two other cows had bronchopneumonia, which was a sequel to osteomyelitis of the fracture site in one. In the absence of a history of trauma, the diagnosis of rib fracture based on clinical signs alone is difficult. Although rib fractures undoubtedly are very painful, the four cases described in this report suggest that they are difficult to diagnose in cattle because associated clinical signs are nonspecific.

    Recent mammographic equipment have been of good quality and yielded high diagnostic accuracy for the detection of breast cancer. However, negative mammogram does not necessarily rule out breast cancer. Therefore were viewed cause of false negative mammography in confirmed breast cancer to improve diagnostic accuracy and for adequate clinical approach. We reviewed 19 cases of confirmed breast cancer, which showed false negative mammography with positive sonographic findings. Retrospective analysis was done by correlating the patient's age, sonographic finding and mass size, mammographic breast pattern and cause of false negative mammogram, and clinical symptoms. Among the 5 patients below 35 years in age, mass was not visible due to dense breast in 4 and due to small size in 1 case. In 14 patients over 35 years in age, 11 had normal mammographic findings, 4 had dense breast, and 7 had small sized mass. Remaining 3 cases showed asymmetric density in 2 and architecture distortion in 1 case. All showed mass lesion in sonography : ill defined malignant appearance in 14,well defined malignant appearance in 2, and well defined benign in 3 cases. Negative mammogram should be correlated with sonography in case of dense breast, below 35 years in age with palpable mass and under risk for breast cancer

    Spinal dural arteriovenous fistula (SDAVF) is a relatively common acquired vascular malformation of the spinal cord. Assessment of a SDAVF is often difficult because of non-specific findings on non-invasive imaging modalities. Diagnosis of a SDAVF is often delayed, and some patients receive unnecessary treatment and treatment delays, often resulting in a poor outcome. The aim of this study was to characterize the clinical presentation, typical imaging findings, and long-term outcome of SDAVF. Forty patients (13 women, 27 men; mean age 58.18 ± standard deviation 14.75 years) who were treated at our hospital from June 1992 to March 2014 were retrospectively reviewed. We investigated the baseline characteristics, clinical presentation, imaging findings, treatment modalities, and outcome of the patients. The most common clinical presentation was a sensory symptom (80%), followed by motor weakness (70%), and sphincter dysfunction (62.5%). Roughly one-third (32.5%) of patients had a stepwise progression of fluctuating weakness and sensory symptoms, but the most common presentation was chronic progressive myelopathic symptoms (47.5%). Thirty-four patients (85%) had T2 signal change on the spinal cord MRI, indicative of cord edema. Thirty-eight patients had typical perimedullary vessel flow voids on T2-weighted MRI. Twenty-eight patients were treated with endovascular embolization, five patients underwent surgery, and four patients underwent both. Clinical outcome was determined by severity of initial deficit (p=0.008), extent of cord edema (p=0.010), treatment failure (p=0.004), and a residual fistula (p=0.017). SDAVF causes a treatable myelopathy, so early diagnosis and intervention is essential. Copyright © 2015 Elsevier Ltd. All rights reserved.

    To describe the clinical and imaging findings of hepatocellular carcinoma with neuroendocrine differentiation, which is an extremely rare variant of hepatocellular carcinoma. We collected five patients who had histopathologically proven hepatocellular carcinoma with neuroendocrine differentiation, and described morphologic feature, enhancement pattern of tumors, extrahepatic manifestation and clinical findings. At CT, the tumor size ranged from 8 to 17 cm (mean: 12 cm) in maximum diameter. The tumor margin was well-defined and smooth in four patients and all tumors were heterogeneously hypoattenuating. Four tumor showed rim enhancement on arterial and portal phases. Local invasion to the portal vein, intrahepatic duct and gallbladder were seen. Extrahepatic manifestations included hepatic metastases, lymph node metastasis. At ultrasonography, the tumor showed heterogeneously hyperechoic in all patients and hypoechoic rim was found in four patients. Of four patients who were followed up, one survived for 16 months after initial diagnosis, while the other three died within 3 months after initial diagnosis. As described above, clinical and imaging findings of hepatocellular carcinoma with neuroendocrine differentiation were not specific. However, this rare variant of hepatocellular carcinoma could be considered when hepatic tumor is found in an advanced stage and shows persistent rim enhancement at CT

    2008-01-01

    This study was to clarify the diagnostic accuracy of clinical findings for internal derangement of the temporomandibular joint (TMJ) compared with that of magnetic resonance imaging. A series of 4559 patients (879 male and 3680 female, mean age 32.7 years; range 8-85 years;) with temporomandibular disorders were clinically examined by un unspecified number of dentists. All patients underwent magnetic resonance imaging (MRI). The clinical findings that characterize disc displacement, anterior disc displacement with reduction (ADDwR) and anterior disc displacement without reduction (ADDwoR) are pain, clicking sound and limitation of maximum mouth opening. These clinical findings were compared to the MRI interpretation, which was used as the gold standard for diagnosis of temporomandibular disorders to define the diagnostic accuracy, specificity, sensitivity, positive predictive value and negative predictive value of clinical findings. The prevalence of clinical finding was 3990 joints (43%) with pain, 2775 joints (30%) with clicking sound and 1731 patients (38%) with limitation of opening. Three thousands forty seven joints were diagnosed as having a normal disc position, 510 joints with sideways disc displacement, 2312 joints with ADDwR, 3239 joints with ADDwoR on MR image. The sensitivity of clinical findings was considerably low: sensitivity was 0.48 for pain versus internal derangement, 0.51 for clicking sound versus ADDwR, 0.62 for limitation of opening versus ADDwoR. The sensitivity was higher in the younger group for clicking sound versus ADDwR, but sensitivity was higher in the older group for limitation of opening versus ADDwoR. The diagnostic accuracy based on clinical findings of internal derangement of TMJ was found to be correlated with age. This study has been that the overall diagnostic accuracy of the clinical findings to determine the status of the joint is about 50-60%. The status of the joint could not be accurately determined by clinical findings

    55 out of 62 patients with cerebral infarction were investigated in terms of CT scan findings, angiographic findings, and clinical symptoms. The results obtained were as follows: 1) The low-density areas of the CT scan findings were classified into the following four types: large hemispheric or lobular --Type I; wedge-shaped --Type II; small --Type III; and lacunar low-density area. --Type IV. 2) Almost all patients with angiographically occlusive findings showed low-density areas of Type I; however, one patient with ICA occlusion revealed only a lacunar low-density area. 3) The patients with lacunar low-density areas showed an angiographically delayed filling of the angular artery and posterior parietal artery of the middle cerebral artery. 4) The relationship between the types of low-density areas and the clinical conscious disorders was not clear. On the other hand, the patients with Type I low-density areas almost all had motor disturbances, while patients with other types of low-density areas showed only 60 - 70% motor disturbances. 5) In patients with speech disorders, total aphasia cases were found in patients with large hemispheric low-density areas on the left side. Although, motor aphasia cases were seen in patients with various low-density areas on the left inferior frontal and precentral gyri, dysarthria cases were found in the patients with several low-density areas on both sides. 6) The localization of lacunar low-density areas seemed to be near the caudate nucleus on the right side and in the putaminal regions on the left side. The mean and the standard deviation of CT numbers in the lacunar low-density areas showed higher values on the right side than on the left side. (author)

Biomicroscopic and multimodal imaging findings were compared with the histopathology of 1 patient. Clinical and histopathologic ocular findings of M. chimaera. The mean age of the 5 male patients, diagnosed with endocarditis or aortic graft infection, was 57.8 years. Clinical ocular findings included anterior and intermediate uveitis, optic disc swelling, and white-yellowish choroidal lesions. Multifocal choroidal lesions were observed bilaterally in all patients and were hyperfluorescent on fluorescein angiography, hypofluorescent on ICG angiography, and correlated with choroidal lesions on SD OCT. The extent of choroidal lesions varied from few in 2 patients to widespread miliary lesions in 3 patients leading to localized choroidal thickening with elevation of the overlying retinal layers. Spectral-domain optical coherence tomography through regressing lesions revealed altered outer retinal layers and choroidal hypertransmission. The ocular findings were correlated with the course of the systemic disease. Patients with few choroidal lesions had a favorable outcome, whereas all patients with widespread chorioretinitis died of systemic complications of M. chimaera infection despite long-term targeted antimicrobial therapy. Ocular tissue was obtained from 1 patient at autopsy. Necropsy of 2 eyes of 1 patient revealed prominent granulomatous lymphohistiocytic choroiditis with

    In recent years, the multislice CT system has come into practical use that enables table movement of half mm, resulting in a significant improvement in resolution. The use of this CT system enables to depict the entire auditory ossicles, including the stapes. 3D reconstruction was performed using helical CT data in 5 patients with chronic otitis media and 5 patients with cholesteatoma. An Aquilion Multi (Toshiba) multislice helical CT scanner and a Xtension (Toshiba) image workstation were used in this study. We demonstrated the 3D display with axial, coronal and sagittal images. Compared with the normal ears, it was necessary to set a higher threshold for the affected ears. It is important to select suitable threshold for demonstration of 3D images optimally. Bone destruction of the stapes was confirmed at surgery in 2 ears. The stapes was observed at 3D-CT imaging in other 18 ears. It was found that the 3D images of the ossicular destruction in ears with cholesteatoma were consistent with surgical findings. It is therefore concluded that 3D imaging of the middle ear using a multislice CT scanner is clinically useful. (author)

    The purpose of this study is to present the clinical and radiographic findings of esophageal lichen planus. A search of computerized medical records identified 15 patients with pathologic findings of esophageal lichen planus on endoscopic biopsy specimens. Three other patients had presumed esophageal lichen planus, although no biopsy specimens were obtained. Twelve of these 18 patients (67%) had double-contrast esophagography performed at our institution; for eight of the 12 patients (67%), the studies revealed abnormalities in the esophagus. These eight patients constituted our study group. The barium esophagrams and medical records of these eight patients were reviewed to determine the clinical, radiographic, and endoscopic findings of esophageal lichen planus as well as the treatment and patient outcome. All eight patients were women (median age, 66.5 years), and all eight presented with dysphagia (mean duration, 3.2 years). Four patients had previous lichen planus that involved the skin (n = 1), the oral cavity (n = 2), or both (n = 1), and one patient later had lichen planus that involved the vagina. Five patients had a small-caliber esophagus with diffuse esophageal narrowing. The remaining three patients had segmental strictures in the cervical (n = 1), upper thoracic (n = 1), and distal thoracic (n = 1) esophagus. Esophageal lichen planus typically occurs in older women with longstanding dysphagia and often develops in the absence of extraesophageal disease. Barium esophagrams may reveal a small-caliber esophagus or, less commonly, segmental esophageal strictures. Greater awareness of the radiographic findings of esophageal lichen planus hopefully will lead to earlier diagnosis and better management of this condition.

    To describe the MR imaging and clinical findings of spontaneous spinal epidural hematoma. The MR and clinical findings in six patients (M:F=3D4:2;adult:child=3D3:3) with spontaneous spinal epidural hematoma were reviewed. Five patients without any predisposing factor which might cause the condition and one with acute myelogenous leukemia were included. Emergency surgery was performed in two patients, and the other four were managed conservatively. The epidural lesion involved between three and seven vertebrae (mean:4.5), and relative to the spinal cord was located in the posterior-lateral (n=3D4), anterior (n=3D1), or right lateral (n=3D1) area. The hematoma was isointense (n=3D1) or hyperintense (n=3D5) with spinal cord on T1-weighted images, and hypointense (n=3D2) or hyperintense (n=3D4) on T2-weighted images. It was completely absorbed in four of five patients who underwent follow-up MR imaging, but not changed in one. The clinical outcome of these patients was complete recovery (n=3D4), spastic cerebral palsy (n=3D1), or unknown (n=3D1). Because of the lesion's characteristic signal intensity; MR imaging is very useful in the diagnosis and evaluation of spontaneous spinal epidural hematoma. (author)

    The aim of this study was to present our experience in MRI diagnosis of 23 patients with the clinical findings suggesting Tolosa-Hunt syndrome (THS). Cranial MRI studies of the patients with a clinical history of at least one episode of unilateral or bilateral orbital and periorbital pain, and associated paresis of one or more of third to sixth cranial nerves, were performed on a 1.5-T MRI scanner. Whereas 5 patients had the diagnosis of THS, paracavernous meningiomas in 4 patients, pituitary macroadenomas with cavernous sinus infiltration in 3 patients, Meckel's cave neurinoma in 1 patient, and suprasellar epidermoid in 1 patient were surgically proven MRI findings. Other pathological MRI findings were leptomeningeal metastases in 3 patients, granulomatous pachymeningitis sequelae in 2 patients, and aneurysm with compression on cavernous sinus in 1 patient. Three patients had normal MRI findings. The incidence of radiologically proven diagnosis of THS among the patients with the clinical findings suggesting THS seemed to be low in our study. In conclusion, MRI is the most valuable imaging technique to distinguish THS from other THS-like entities, and permits a precise assessment, management, and therapeutic planning of the underlying pathological conditions.

    This paper reports on the condition of the middle ear cavity following tympanoplasty which is always of great interest to radiologists and otosurgeons. This study consisted of 21 patients who had various types of tympanoplasty (types I-IV) for chronic otitis media and cholesteatoma by using high-resolution CT (HRCT). HRCT following tympanoplasty was a valuable method for assessing the middle ear aeration and the state of ossicular reconstruction, including stapes prosthesis, although in some cases of soft-tissue mass in the middle ear it was necessary to correlate with clinical findings in order to differentiate between granulation and recurrence

    In the setting of clinically suspected Legg-Calve-Perthes (LCP) disease and negative/equivocal radiographs, contrast-enhanced MRI can be performed to confirm the diagnosis. To determine the frequency of unexpected causes of hip pain as identified by MRI in children with clinically suspected LCP disease and negative/equivocal radiographs. All pediatric contrast-enhanced MRI examinations of the pelvis and hips performed between January 2000 and February 2009 to evaluate for possible LCP disease in the setting of negative/equivocal radiographs were identified. MRI examinations performed to evaluate for secondary avascular necrosis were excluded. Imaging reports were retrospectively reviewed for unexpected clinically important causes of hip pain. Thirty-six pediatric patients underwent contrast-enhanced MRI examinations for clinically suspected LCP disease in the setting of negative/equivocal radiographs. Twenty-two (61%) imaging studies were normal, while four (11%) imaging studies demonstrated findings consistent with LCP disease. Ten (28%) imaging studies revealed unexpected clinically important causes of hip pain, including nonspecific unilateral joint effusion and synovitis (n = 7, juvenile chronic arthritis was eventually diagnosed in 3 patients), sacral fracture (n = 1), apophyseal injury (n = 1), and femoral head subluxation (n = 1). MRI frequently reveals unexpected clinically important causes of hip pain in children with suspected LCP disease and negative/equivocal radiographs. (orig.)

    Full Text Available BACKGROUND AND AIM: The aim of this study was to assess the association between the clinical and cone-beam computed tomography (CBCT findings in relation to bony changes in patients with temporomandibular disorders (TMD. METHODS: According to the research diagnostic criteria for temporomandibular disorder (RDC/TMD, forty-one patients with type II TMD (42 TM joints and type III TMD (40 TM joints were recruited for this study. Condylar position and bony changes including flattening, sclerosis, osteophytes, resorption, and erosion of joint were evaluated by CBCT and compared with clinical findings. Data were analyzed by SPSS software. RESULTS: Condylar flattening, sclerosis, resorption, and erosion were not significantly associated with joint/masticatory muscles pain or crepitus sound. The vertical or horizontal position of the condyle showed no significant relationship with the clinical findings. Condylar osteophyte was significantly associated with pain in masticatory muscles and crepitus (P = 0.030 and P = 0.010, respectively. There was no association between the condylar range of motion and pain in joint or masticatory muscles. CONCLUSION: Condylar osteophyte was significantly associated with both masticatory muscles pain and crepitus sound. No significant relationship was found between the other temporomandibular joint (TMJ radiographic and clinical findings in patients with TMD.

    Hip dysplasia is a common developmental disorder of the dog, consisting of varying degrees of hip laxity, progressive remodeling of the structures of the hip, and subsequent development of osteoarthritis. It is a juvenile-onset condition, with clinical signs often first evident at 4 to 12 months of age. A tentative diagnosis of hip dysplasia can be made based on signalment, history, and physical examination findings. The Ortolani test is a valuable tool for identifying juvenile dogs affected with this condition. Further diagnostics can then be prioritized, contributing to prompt diagnosis and appropriate treatment. Copyright © 2017 Elsevier Inc. All rights reserved.

    The aim of this study was to assess the clinical and pulmonary thin-section CT findings in patients with acute Klebsiella pneumoniae pneumonia. We retrospectively evaluated thin-section CT examinations performed between January 1991 and December 2007 from 962 patients with acute Klebsiella pneumoniae pneumonia. Seven hundred and sixty-four cases with concurrent infectious diseases were excluded. Thus, our study group comprised 198 patients (118 male, 80 female; age range 18-97 years, mean age 61.5). Underlying diseases and clinical findings were assessed. Parenchymal abnormalities were evaluated along with the presence of enlarged lymph nodes and pleural effusion. CT findings in patients with acute Klebsiella pneumoniae pneumonia consisted mainly of ground-glass attenuation (100%), consolidation (91.4%), and intralobular reticular opacity (85.9%), which were found in the periphery (96%) of both sides of the lungs (72.2%) and were often associated with pleural effusion (53%). The underlying conditions in patients with Klebsiella pneumoniae pneumonia were alcoholism or smoking habit. (orig.)

    Acute bacterial meningitis often results in significant neurologic complications regardless of the antibiotics treatment Computed tomographic (CT) finding of tuberculous meningitis is fairly well known but not the findings of bacterial meningitis. This study was performed to determine the incidence of causative organisms and to correlate between the organisms and computed tomographic (CT) findings with clinical outcome of bacterial meningitis in newborns and infants. We analyzed the brain CT and clinical records of 15 infants who had been diagnosed as bacterial meningitis by CSF culture. We found that the most common organisms were Group B streptococcus in neonates without no neurologic complications in all but one and Hemophilus influenza in infants whose clinical outcomes were poor in all except one. CT findings related with poor prognosis in this study were cerebral edema, basal cisternal obliteration and enhancement, and cerebral infarction on initial CT and ventriculomegaly on follow-up CT. We concluded that CT diagnosed intracranial complications of bacterial meningitis well and could contributed to better treatment of bacterial meningitis

    Aim: To assess the clinical, computed tomography (CT), and pathological findings in patients with lymphoplasmacytic sclerosing cholangitis. Materials and methods: Fifteen consecutive patients (four women and 11 men, mean age 71 years) with lymphoplasmacytic sclerosing cholangitis and without the characteristic features of underlying disorders causing benign biliary strictures were retrospectively recruited. Two radiologists evaluated multiphase contrast-enhanced CT images acquired with 0.5 or 1-mm collimation. One pathologist performed all histological examinations, including IgG4 immunostaining. Results: The intrahepatic biliary ducts showed dilatation in all 15 patients, but only seven presented with jaundice. Although laboratory data were not available in all patients, serum gammaglobulin and IgG levels were elevated in five of six patients and six of eight patients, respectively. Anti-nuclear antibody was detected in three of six patients. The involved biliary ducts showed the following CT findings: involvement of the hilar biliary duct (14/15), a mean wall thickness of 4.9 mm, a smooth margin (10/15), a narrow but visible lumen (6/15), hyper-attenuation during the late arterial phase (9/15), homogeneous hyper-attenuation during the delayed phase (11/11), and no vascular invasion (14/15). Abnormal findings in the pancreas and urinary tract were detected in eight of 15 patients. In 13 patients with adequate specimens, moderate to severe lymphoplasmacytic infiltration associated with dense fibrosis was observed. Infiltration of IgG4-positive plasma cells was moderate or severe in nine patients and minimal or absent in four patients. Conclusion: Lymphoplasmacytic sclerosing cholangitis exhibits relatively characteristic clinical and CT findings, although they are not sufficiently specific for differentiation from other biliary diseases.

    Incidental cardiovascular findings are a frequent phenomenon in computed tomography (CT) examinations. As the result of a dedicated PubMed search this article gives a systemic overview of the current literature on the most important incidental cardiovascular findings, their prevalence and clinical relevance. The majority of incidental cardiovascular findings are of only low clinical relevance; however, highly relevant incidental findings, such as aortic aneurysms, thromboses and thromboembolic events can also occasionally be found, especially in oncology patients. The scans from every CT examination should also be investigated for incidental findings as they can be of decisive importance for the further clinical management of patients, depending on their clinical relevance. (orig.) [German] Inzidentelle kardiovaskulaere Befunde sind ein haeufiges Phaenomen bei CT-Untersuchungen. Mit dieser Arbeit soll nach gezielter PubMed-Recherche ein systematischer Literaturueberblick ueber die wichtigsten kardiovaskulaeren Zufallsbefunde sowie deren Haeufigkeit und klinische Relevanz gegeben werden. Die Mehrzahl der inzidentellen kardiovaskulaeren Befunde sind klinisch nur von untergeordneter Bedeutung, allerdings werden immer wieder auch hochgradig relevante Zufallsbefunde wie beispielsweise Aortenaneurysmata oder - gerade bei onkologischen Patienten - Thrombosen und thrombembolische Ereignisse detektiert. Jede CT-Untersuchung sollte gezielt nach inzidentellen Befunden durchsucht werden, da diese je nach klinischer Relevanz von entscheidender Bedeutung fuer das weitere klinische Management des Patienten sein koennen.

    IMPORTANCE Clinical whole-exome sequencing is increasingly used for diagnostic evaluation of patients with suspected genetic disorders. OBJECTIVE To perform clinical whole-exome sequencing and report (1) the rate of molecular diagnosis among phenotypic groups, (2) the spectrum of genetic alterations contributing to disease, and (3) the prevalence of medically actionable incidental findings such as FBN1 mutations causing Marfan syndrome. DESIGN, SETTING, AND PATIENTS Observational study of 2000 consecutive patients with clinical whole-exome sequencing analyzed between June 2012 and August 2014. Whole-exome sequencing tests were performed at a clinical genetics laboratory in the United States. Results were reported by clinical molecular geneticists certified by the American Board of Medical Genetics and Genomics. Tests were ordered by the patient’s physician. The patients were primarily pediatric (1756 [88%]; mean age, 6 years; 888 females [44%], 1101 males [55%], and 11 fetuses [1% gender unknown]), demonstrating diverse clinical manifestations most often including nervous system dysfunction such as developmental delay. MAIN OUTCOMES AND MEASURES Whole-exome sequencing diagnosis rate overall and by phenotypic category, mode of inheritance, spectrum of genetic events, and reporting of incidental findings. RESULTS A molecular diagnosis was reported for 504 patients (25.2%) with 58% of the diagnostic mutations not previously reported. Molecular diagnosis rates for each phenotypic category were 143/526 (27.2%; 95% CI, 23.5%–31.2%) for the neurological group, 282/1147 (24.6%; 95% CI, 22.1%–27.2%) for the neurological plus other organ systems group, 30/83 (36.1%; 95% CI, 26.1%–47.5%) for the specific neurological group, and 49/244 (20.1%; 95% CI, 15.6%–25.8%) for the nonneurological group. The Mendelian disease patterns of the 527 molecular diagnoses included 280 (53.1%) autosomal dominant, 181 (34.3%) autosomal recessive (including 5 with uniparental disomy

    As little is known about the oxidant/antioxidant status in buffalo with ketosis, the present study was delineated to assess the oxidative stress level associated with clinical ketosis in water buffalo. A total of 91 parturient buffalo at smallholder farms were studied (61 suspected to be ketotic and 30 healthy). Clinical and biochemical investigations were carried out for each buffalo. Based on clinical findings and the level of beta-hydroxybutyrate (BHB), buffalo were allocated into ketotic (42), subclinical cases (19). Clinically, there was an association between clinical ketosis and anorexia (pketosis compared with subclinical and control cases, there was a significant increase (pketosis.

    63 cases of meningitis in children were reviewed to study correlated between brain CT findings and clinical course. We divided 63 cases into 3 groups according to clinical course, that is , Group I: Healed without significant sequelae. Group II: Discharged with sequelae such as neurologic deficit or complicated clinical course. Group III: Expired or considered to be expired after hopeless discharge. The CT findings were retrospectively analyzed and compared with each clinical group. We drawed several conclusions as follows: 1. The wrost prognostic CT findings is dirty basal cisternal enhancement. ( Group I only 5%, Group II 50%, Group III 45%). 2. Focal brain parenchymal lesion, especially multiple, such as granuloma and infarct shows unfavorable clinical outcome, that is , high rate of Group III and evident neurologic deficit, in contrast to only 7% of Group I. 3. In 7 case of which CT findings is only hydrocephalus, the prognosis is rather favorable, that is 57% were Group I, 43% were improved after V-P shunt (Group II) and no Group III. But hydrocephalus with dirty cisternal enhancement results in grave prognosis, that is, Group I only 8%, Group II 54%, Group III 38%. With regard to overall hydrocephalus, predilection for good or bad prognosis can't be mentioned. 4. No prognostic difference were noted between presence and absence of periventricular low density in hydrocephalus. 5. CSF pressure of hydrocephalus is mostly high (over 20 cm H 2 O), but normal pressure hydrocephalus were noted in 24%. CSF pressure of normal ventricle size is mostly under 18 cm H 2 O but high pressure were noted in 18 % of the normal sized ventricle (most of them shows intracranial space occupying lesion such as granuloma, accute infarct, subdural effusion, etc). 6. Most of diffuse brain swelling, diffuse brain atrophy and subdural effusion result in Group I , that is , favorable clinical outcome. 7. Normal CT findings are found in 29%, of which 61% belong to Group I and 31% to Group

    To evaluate the MRI findings of acute facial nerve paralysis in Bell's palsy and herpes zoster opticus, and to correlate these with the clinical findings. We retrowspectively reviewed the MRI findings in six cases of BEll's palsy(BP) and two of herpes zoster oticus(HZO), and compared them with the findings for 30 normal facial nerves. This nerve was considered abnormal when its signal intensity was greater than that of brain parenchyma or the contralateral normal side on Gd-enhanced T1-weighted axial and coronal MR images. We analysed the location and degree of contrast enhancement, interval change, and clinical progression in correlation with House-Brackmann(HB) grade and electroneuronography (ENoG) findings. Fifteen of 30 normal facial nerves(50%) seen on Gd-enhanced MRI were mildly enhanced in the geniculate ganglion, the proximal tympanic, and the proximal mastoid segment of the facial nerve. No enhancement of the internal auditory canal(IAC) or labyrinthine segment of the facial nerve was noted, however. In BP and HZO, Gd-enhanced MR images revealed fair to marked enhancement for more than two segments from the internal auditory canal to the mastoid segment of the facial nerve. During follow-up MRI, enhancement of the facial nerve varied in location and signal intensity, though gradually decreased in intensity approximately eight weeks after the onset of facial nerve palsy. No correlation between clinical HB grade, ENoG, and follow up MRI findings was noted. Except in the internal auditory canal and labyrinthine segment, normal facial nevemay show mild and relatively symmetrical enhancement. In BP and HZO, the facial nerve showed diffuse enhancement from the IAC to the mastoid segment.=20

    The purpose of this series was to review the spectrum of clinical and sonographic features associated with infection after nipple piercing. Between 2002 and 2010, 6 patients presented to our breast center with a breast abscess after nipple piercing. A retrospective analysis of the imaging findings was performed with clinical and pathologic correlation. Patients with breast infections after nipple piercing tend to be young, and the timing since piercing varies from 2 weeks to 17 months. Sonography showed a complex or hypoechoic mass in 5 of 6 patients. Treatment of breast abscesses included surgical incision and drainage, percutaneous drainage, and antibiotic therapy. Surgical evacuation is commonly performed; however, sonographically guided aspiration may be an appropriate management strategy.

    Purpose: To define the diagnostic criteria of osteogenesis imperfection. Materials and methods: The clinical and radiologic manifestations of 68 patients with osteogenesis imperfection were studied retrospectively. Results: (1) A generalized decrease in osseous density (osteoporosis or osteopenia) with abnormal fragility of bone (68 cases). (2) Blue sclera (61 cases). (3) Dentinogenesis imperfection with opalescent bluish-gray tint (49 cases). (4) Progressive hearing loss (prior to the age of 40 years)-premature otosclerosis (38 cases). Other abnormalities such as abnormal contour and structure (68 cases), growth retardation (49 cases), episodic diaphoresis (24 cases), with abnormal temperature regulation (16 cases), hyperplastic scars (11 cases) and tendency of subcutaneous bruise (6 cases), all these were not characteristic features. Conclusion: Among all clinical and radiological findings, osteopenia with abnormal fragility of bone; blue sclera dentinogenesis imperfection with opalescent bluish-gray tint and premature otosclerosis are the most common and characteristic findings which can be taken as the diagnostic criteria of osteogenesis imperfection

    Phenylketonuria (PKU) is the most common form of amino acid metabolism disorders with autosomal recessive inheritance. The brain damage can be prevented by early diagnosis and a phenylalanine-restricted diet. Untreated or late-treated patients may show mental retardation and other cognitive dysfunctions, as well as motor disability and/or epilepsy. Three patients with PKU and epilepsy were recognized to have reflex epileptic features, and there were ten consecutive adult patients with PKU and epilepsy who were evaluated retrospectively. Medical history, ages at diagnosis and therapy onset, age at seizure onset, seizure types and reflex features, neurological findings, cranial imaging, electroencephalography (EEG) findings, and final clinical condition were evaluated. Reflex epilepsy features were examined in detail. The cases (6 females, 4 males) were diagnosed at ages between 3.5months and 12years. All patients had various degrees of mental-motor retardation and focal or generalized seizures with age at seizure onset varied between neonatal period and 15years. Three patients had febrile seizure, 3 patients had myoclonia, and 3 patients had status epilepticus. All patients had abnormal EEG findings except one. There was a slowing of background activity, and generalized discharges were observed in 7 patients; 3 of them had asymmetrical discharges. One patient had right hippocampal sclerosis (HS), and another patient had hypointensities in the basal ganglia and corpus callosum. Reflex features were clinically observed in 3 of the patients; however, EEG results did not show any related findings. One patient had reflex seizures triggered by photic stimuli, hot water, and startling; one by photic stimuli; and the other one by startling. Reports on the clinical and electrophysiological features of adult patients with PKU were scant. We emphasized that reflex clinical features may be observed in this metabolic disease, and focal epileptiform abnormalities and asymmetry

    Objective: To investigate the characteristic clinical and X-ray findings of mycetoma and to enhance the understanding of mycetoma. Methods: The clinical and X-ray findings of mycetoma in 18 cases were analyzed with the review of literatures. There were 11 males and 7 females, the age ranged from 21-65 years, with the average of 41.5 year. The cases were all peasants, barefoot and with the history of trauma, which lasted for 4-17 years with the average of 9.8 year. Results: Sixty-seven lesions of bone in 18 cases (30 metatarsal, 20 cuneiform, 7 cuboid, 5 phalanx, 3 tibia, 2 calcaneus) were presented, including 8 rodent, 3 osteolytic, 3 cystic, 2 rodent and sclerosis changes, 2 sclerosis, 9 irregular thickened bony cortex, 7 irregular deleted bony cortex, 12 periosteal reaction, 3 irregular crest of bone in lesion, 13 rarefaction of bone cortex, 11 swimmy of surface arthrosis, 8 constriction of interval arthrosis, 2 spot calcification in the soft tissue, 2 sequestrum, and 2 soft tissue mass. The mycelium had been discovered in grain in 18 cases and the colour of grain was from brown to black. Conclusion: Mycetoma involves extensively and tends to involve multiple bones. The main X-ray findings are rodent and osteolytic changes

    Full Text Available There is a wide differential diagnosis for the child with unexplained fractures including non-accidental injury, osteogenesis imperfecta and vitamin D deficiency rickets. Over the last 20 years we and others have described a self-limiting syndrome characterised by fractures in the first year of life. This has been given the provisional name temporary brittle bone disease. This work had proved controversial mostly because the fractures, including rib fractures and metaphyseal fractures, were those previously regarded as typical or even diagnostic of non-accidental injury. Some have asserted that the condition does not exist. Over the years 1985 to 2000 we investigated 87 such cases with fractures with a view to determining the future care of the children. In 85 of these the judiciary was involved. We examined the clinical and radiological findings in the 33 cases in which there was a judicial finding of abuse, the 24 cases in which the parents were exonerated and the 28 cases in which no formal judicial finding was made. The three groups of patients were similar in terms of demographics, age at fracturing and details of the fractures. The clinical similarities between the three groups of patients contrasts with the very different results of the judicial process.

    In early detection work, recruiting individuals who meet the prodromal criteria is difficult. The aim of this paper was to describe the development of a research clinic for individuals who appear to be at risk of developing a psychosis and the process for educating the community and obtaining referrals. The outcome of all referrals to the clinic over a 4-year period was examined. Following an ongoing education campaign that was over inclusive in order to aid recruitment, approximately 27% of all referrals met the criteria for being at clinical high risk of psychosis. We are seeing only a small proportion of those in the community who eventually go on to develop a psychotic illness. This raises two important issues, namely how to remedy the situation, and second, the impact of this on current research in terms of sampling bias and generalizability of research findings. © 2008 The Authors.

    Full Text Available The present study was carried out to describe the clinical picture of traumatic reticuloperitonitis (TRP in water buffalo (Bubalus bubalis and to evaluate the inflammatory and immunologic responses for this clinical condition. Twenty-two buffalo with acute local TRP were monitored in our study. Additionally, 10 clinically healthy buffalo were randomly selected and served as controls. Acute local TRP was initially diagnosed by clinical examination and confirmed by ultrasonographic (USG examination and/or necropsy findings. Blood samples were collected from all examined buffalo to measure the respective levels of tumor necrosis factor alpha (TNF-α, interleukin (IL-1β, IL-6, IL-10 and interferon gamma (INF-γ, serum amyloid A (SAA, C-reactive protein (CRP, haptoglobin (Hp, fibrinogen (Fb, and serum sialic acid (SSA. It was found that TNF-α, IL-1β, IL-6, IL-10, SAA, CRP, Hp, Fb, and SSA were significantly higher in buffalo with TRP than the controls. Our findings suggest that the examined immunologic variables were helpful in documenting the inflammatory response in buffalo with TRP. However, their diagnostic usefulness only becomes apparent when considered in tandem with the clinical findings for any given animal, its anamnesis, and a subsequent USG assessment. Due to the frequent complications of TRP, more accurate indicators of its occurrence and severity would be useful.

    To assess how accurately computed tomography (CT) can demonstrate the abnormal findings which are believed to cause the clinical signs and symptoms of hearing loss (HL), vertigo and facial paralysis (FP) in patients with temporal bone trauma. The authors studied CT scans of 39 ears in 35 patients with temporal bone trauma. CT scans were performed with 1-1.5 mm slice thickness and table incrementation. Both axial and coronal scans were obtained in 32 patients and in three patients only axial scans were obtained. We analyzed CT with special reference to the structural abnormalities of the external auditory canal, middle ear cavity, bony labyrinth, and facial nerve canal, and correlated these findings with the actual clinical signs and symptoms. As to hearing loss, we evaluated 32 ears in which pure tone audiometry or brainstem evoked response audiometry had been performed. With respect to the specific types of HL, CT accurately showed the abnormalities in 84% (16/19) in conductive HL, 100% (2/2) in sensorineural HL, and 25% (2/8) for mixed HL. When we categorized HL simply as conductive and sensorineural, assuming that mixed be the result of combined conductive and sensorineural HL, CT demonstrated the abnormalities in 89% (24/27) for conductive HL and 50% (5/10) for sensorineural HL. Concerning vertigo and FP, CT demonstrated abnormalities in 67%(4/6), and 29% (4/14), respectively. Except for conductive HL, CT seems to have a variable degree of limitation for the demonstration of the structural abnormalities resulting sensorineural HL, vertigo or facial paralysis. It is imperative to correlate the CT findings with the signs and symptoms in those clinical settings.

    To describe clinical and MRI findings of growth hormone-secreting pituitary adenoma, to determine if there are any characteristic MRI findings different from those of other pituitary adenomas, to evaluate the relationship between tumor size and serum growth hormone level, and to assess the results of immunohi-stochemical study. We retrospectively analysed clinical and MRI findings of 29 patients with growth hormone-secreting pituitary adenoma confirmed by serum growth hormone level and surgery. We also evaluated the relationship between the tumor volume and serum growth hormone level, and the results of immunohistochemical study. Coronal and sagittal T1-weighted MR images in all patients and gadolinium-enhanced T1-weighted MR images in 28 patients were obtained with 2.0 T(24 cases) and 0.5 T(5 cases) MR imagers. The images were analyzed in terms of tumor size, signal intensity, degree of contrast enhancement, extent of tumor growth and the presence or absence of cystic change, hemorrhage and calcification. Clinical manifestations included facial feature change and soft tissue swelling of hands and feet(n=29), headache(n=12), impaired visual acuity(n=9), symptoms of hyperprolactinemia(n=8), visual field defect(n=5), and others(n=6). On MR images, all of the 29 cases were seen to be macroadenomas and the size of the tumors averaged 2.2cm(1-5.2cm). Supra- and infrasellar extensions were seen in 21 and 22 patients, respectively. Cavernous sinus invasion was noted in seven, and in one this was bilateral. Signal intensity was isointense with cortical grey matter in 26 cases(90%). Cystic change or necrosis was seen in eight cases(28%), hemorrhage in four(14%), and calcification in two(7%). After enhancement, most(25/28) of the tumors enhanced less than normal pituitary in degree. There was no correlation between serum growth hormone level and tumor size. Immunohistochemical study showed positive growth hormone-secreting pituitary adenomas were various and included

    Primary hyperoxaluria is a rare autosomal recessive inborn error of metabolism with three known subtypes. In primary hyperoxaluria type 1, the most common of the subtypes, a deficiency in the hepatic enzymes responsible for the metabolism of glycoxylate to glycine, leads to excessive levels of glyoxylate, which is converted to oxalate. The resultant elevation in serum and urinary oxalate that characterizes primary hyperoxaluria leads to calcium oxalate crystal deposition in multiple organ systems (oxalosis). We review the genetics, pathogenesis, variable clinical presentation and course of this disease as well as its treatment. Emphasis is placed on the characteristic imaging findings before and after definitive treatment with combined liver and renal transplantation. (orig.)

    Neurological complications are a rare but important and significant source of information about morbidity and mortality in liver transplant patients. Based on the clinical and radiological findings of 21 patients, neurological complications were categorized into five main groups; focal hemorrhagic or occlusive complications (n=11); diffuse hypoxic-ischemic injury (n=3); hypertensive encephalopathy (n=1); central pontine or extra-pontine myelinolysis (n=4); and infection (n=2). Neurological manifestations varied according to the location of the lesion, although seizures were the most common manifestation. In this pictorial review, we illustrate the radiological findings, focusing on MR and CT images, of a spectrum of neurological complications following liver transplants, as well as their clinical correlations.

    Fat within the filum terminale is frequently seen on routine magnetic resonance imaging (MRI) of the lumbosacral spine (LSS), with prevalence of 1–5%. The objective of this study was to determine the prevalence and MRI features of isolated lipoma of filum terminale (LFT) in adult population and its correlation with the patient clinical presentations. Prospective analysis of all lumbosacral MRI performed at King Abdullah University Hospital during a 21-month period. A total of 37 patients with LFT were included. Patients were divided into two groups. Group A patients have neurological deficit manifested by either motor, sensory or sphincter abnormality. Group B patients have normal neurological examination. Clinical findings were correlated with: A: thickness of LFT, B: length of LFT, C: distance of LFT from conus medullaris (CM), D: age of the patient. The prevalence of isolated LFT in our study was 3.2%. There was no significant correlation between the thickness or length of LFT and the presence of neurological deficit. The distance of LFT from CM was also not correlated with the patient clinical presentation. No significant difference in the age between the two groups. LFT in adult likely represent an incidental finding on routine lumbosacral MRI. Special attention for LFT in children is mandatory as it may indicate clinical tethering in otherwise normal appearing LSS.

    To evaluate the radiological findings and clinical course of the complications arising after nonbiliay laparoscopic gastrointestinal surgery (NLGS). We retrospectively reviewed the clinical records of 131 patients who underwent NLGS (83 cases involving colorectal surgery, 18 splenectomies, 14 appendectomies, ten adrenalectomies, three lumbar sympathectomies, two Duhamel's operation, and one peptic ulcer perforation repair) over a four-year period. Among these 131 patients, the findings of fifteen in whom postoperative complications were confirmed were analysed. The radiologic examinations these patients underwent included CT (n=3D8), barium enema and fistulography (n=3D4), ultrasonography (n=3D3), ascending venography of the lower legs (n=3D2), and penile Doppler sonography (n=3D1). We evaluated the radiologic findings and clinical courses of early (within 2 weeks) and late (after 2 weeks) postoperative complications. Sixteen cases of postoperative complications developed in fifteen patients ; in 14 (17%) after colorectal surgery and in one (6%) after splenectomy. Eleven of the sixteen cases (69%) involved early complications, consisting of an abscess in three, ischemic colitis in two, hemoperitoneum in one, perforation of the colon in one, pancreatitis in one, recto-vaginal fistula in one, deep vein thrombosis after colorectal surgery in one, and abscess after splenectomy in one. The remaining five cases (31%) involved late complications which developed after colorectal surgery, comprising anastomosic site stricture in two, abdominal wall (trocar site) metastasis in one, colo-cutaneous fistula in one, and impotence in one. Among the 16 cases involving postoperative complications, recto-vaginal fistula, colon perforation, and abdominal wall metastasis were treated by surgery, while the other thirteen cases were treated conservatively. Various postoperative complications develop after NLGS, with a higher rate of these being noted in cases involving colorectal

Eleven of the sixteen cases (69%) involved early complications, consisting of an abscess in three, ischemic colitis in two, hemoperitoneum in one, perforation of the colon in one, pancreatitis in one, recto-vaginal fistula in one, deep vein thrombosis after colorectal surgery in one, and abscess after splenectomy in one. The remaining five cases (31%) involved late complications which developed after colorectal surgery, comprising anastomosic site stricture in two, abdominal wall (trocar site) metastasis in one, colo-cutaneous fistula in one, and impotence in one. Among the 16 cases involving postoperative complications, recto-vaginal fistula, colon perforation, and abdominal wall metastasis were treated by surgery, while the other thirteen cases were treated conservatively. Various postoperative complications develop after NLGS, with a higher rate of these being noted in cases involving colorectal

    Full Text Available Objective:This study was performed to identify serum 25-OH vitamin D levels and to investigate the relationship between 25-OH vitamin D and clinical findings on patients with fibromyalgia syndrome (FMS. Methods:Nineteen premenopausal women with FMS who were diagnosed according to ACR 1990 fibromyalgia diagnostic criteria and 24 premenopausal healthy women as control group were included in the study. Serum 25-OH vitamin D levels were determined in both patient and control groups. Widespread body pain, headache, fatigue, morning stiffness, sleep disorder, the number of tender points, Fibromyalgia Impact Questionnaire (FIQ scores and Beck depression scores were evaluated as clinical findings in patients with FMS. Results:Serum 25-OH vitamin D levels were significantly lower in patients with FMS than those in control group (p=0.01. There were significantly negative correlations between 25-OH vitamin D levels and widespread body pain (r=-0.731, Beck depression scores (r=-0.777, headache (r=-0.629, and sleep disorder (r=-0.767 in the FMS group (p<0.01. Conclusion: It was concluded that 25-OH vitamin D deficiency may be related to the clinical findings such as widespread body pain, depression, headache and sleep disorder in patients with FMS.

    Full Text Available Eosinophilic esophagitis (EE is a motility disorder of the esophagus that typically presents with dysphagia. The objective of the present study was to explore patient characteristics, clinical and endoscopic features, and response to treatment of patients with EE. Patients were selected retrospectively based on a review of biopsy results from previous endoscopies performed between 2004 and 2008. A total of 54 patients (41 men and 13 women with biopsy-proven EE were included in the study. Further information regarding the patients’ clinical and endoscopic features, and response to treatment were obtained through chart reviews and patient telephone interviews. The mean age of the patients at symptom onset was 30 years. All patients complained of dysphagia, 81% had a history of bolus obstruction, 43% had a history of asthma and 70% had a history of environmental allergies. Thirty-three per cent had a family history of asthma, while 52% had a family history of food or seasonal allergies. The most common endoscopic findings were rings and/or corrugations, which were found in 63% of patients. Swallowed fluticasone therapy resulted in symptom resolution in 74% of patients; however, 79% of these patients relapsed after discontinuing fluticasone therapy and required repeat treatments. Esophageal dilation was complication free and resulted in improvement in 80% of patients. However, 83% of those reporting improvement relapsed within one year. The clinical and endoscopic findings were similar to those found in the literature, with most patients requiring ongoing, repeated therapies. Further studies are needed to assess the safety and efficacy of treatment modalities ideally suited to patients with EE.

    Infective endocarditis (IE) is an infection that develops on the endothelial surface of the heart. Endocarditis is a major problem for the clinicians despite of the developments in diagnostic, surgical, and medical treatment methods. In this study, we aimed to evaluate symptoms, laboratory findings, treatment options, and clinical endpoint of the patients who were diagnosed with IE in a tertiary healthcare organization according to the literature data. Between January 2006 and March 2013, 80 IE patients who were diagnosed and treated in accordance with modified Duke criteria were enrolled in the study. Demographic features, symptoms, and laboratory and echocardiographic findings were recorded after reviewing the patient files. The mean age of the patients was 51.3 ± 16.0, and IE was more common in men (n = 56; 70%). Of 41 patients who had positive blood cultures, 20 patients had Staphylococcus spp. (48.7%) and 8 patients had Streptococcus spp. (19.5%). Brucella spp. was isolated from 5 patients (12.2%). While 48.7% (n = 39) of the patients had cardiac complications, 22 patients (27.5%) had embolic complication. Hospital mortality was observed in 20 patients (15%). In our patients, endocarditis was seen at a young age, and staphylococci were the most frequently isolated microorganism from blood culture. There were more patients with Brucella endocarditis compared to the general population. Complications are frequently seen in the course of endocarditis, and they cause problems for the clinicians during follow ups due to the high mortality rate of IE.

    Clinical and computed tomography (CT) findings of twenty-three patients with acoustig neurinoma (AN) and eleven patients with posterior fossa meningioma (PFM) are described. AN frequently (94%) presents with the complaint of hearing loss, while PFM often (60%) presents with non-specific pains in the head or neck. The CT characteristics of AN and PFM in this series were similar to those found in most previous publications. The maximal measured mean diamter of PFM (40.2 mm) was significantly larger than that of AN (26.4 mm). Hydrocephalus was apparently influenced by tumor location rather than by its size. It is concluded that diagnostic ability has been improved in cases of CPA tumors, but not in those of non-CPA PFM, probably because of the earlier clinical presentation of the former. Clinical efforts are still necessary to detect the smaller tumors. (orig.)

    Full Text Available OBJECTIVE: To evaluate mammographic breast density in asymptomatic menopausal women in correlation with clinical and sonographic findings. MATERIALS AND METHODS: Mammograms and clinical and sonographic findings of 238 asymptomatic patients were retrospectively reviewed in the period from February/2022 to June/2006. The following variables were analyzed: mammographic density patterns, sonographic findings, patients' age, parity, body mass index and use of hormone replacement therapy. RESULTS: Age, parity and body mass index showed a negative correlation with breast density pattern, while use of hormone replacement therapy showed a positive correlation. Supplementary breast ultrasonography was performed in 103 (43.2% patients. Alterations which could not be visualized at mammography were found in 34 (33% of them, most frequently in women with breast density patterns 3 and 4. CONCLUSION: The authors concluded that breast density patterns were influenced by age, parity, body mass index and time of hormone replacement therapy. Despite not having found any malignant abnormality in the studied cases, the authors have observed a predominance of benign sonographic abnormalities in women with high breast density patterns and without mammographic abnormalities, proving the relevance of supplementary ultrasonography to identify breast lesions in such patients.

    In this work we did a sectional study of 31 asthmatic patients with several levels of disease severity, which were submitted to high resolution computed tomography of the thorax and spirometry, between the months of July, 1995 and August, 1997. The tomographic findings were correlated with the clinical classification of the patients and the most frequent tomographic findings were bronchial wall thickening, bronchial dilatation, air trapping, centrilobular opacities, cicatricial linear shadows, mucoid impaction, emphysema and atelectasis. In asthmatic patients of long duration we observed small airway disease and irreversible lesions as the predominant findings. In smoking patients there was no high frequency of emphysema. (author)

    To evaluate the correlation of clinical, laboratory, and pathological features at pre-sentation of focal segmental sclerosis (FSGS), we reviewed in a cross sectional study the pathological findings of kidney biopsies in 64 cases of primary FSGS, and correlated them with the clinical and laboratory data obtained at the time of the biopsies. The data included blood pressure, glomerular filtration rate (GFR), serum albumin, and the level of proteinuria. The mean level of serum creatinine was significantly higher in the biopsies' findings of synechiae (adhesions) in the Bowman's capsule, interstitial fibrosis, and global scars (PBowman's capsule in their biopsies.

    Cerebral computed tomography (CT) findings were described in twenty-six cases with the late sequelae of acute carbon monoxide poisoning and were computed with the neurological symptoms and signs. The CT findings include symmetrical periventricular white matter low density in five cases, globes pallidus low density in six cases, ventricular dilatation in seven cases, ventricular dilatation and sulci widening in three cases, and normal findings in ten cases. Only one case showed low densities in both periventricular white matter and globes pallidus. Late sequelae of the interval from of carbon monoxide poisoning were clinically categorized as cortical dysfunction, parkinsonian feature, and cerebella dysfunction. The severity of the clinical symptoms and signs of neurological sequelae is generally correlated with presence and multiplicity of abnormal brain CT findings. But of fourteen cases showing the parkinsonian feature, only five cases had low density of globes pallidus in brain CT. Another case showing small unilateral low density of globes pallidus had no parkinsonian feature but showed mild cortical dysfunction.

    Clinical signs, duration of illness, clinicopathologic findings, and ultrasonographic findings were evaluated in 12 llamas and 12 alpacas with malignant round cell tumors (MRCT). All but 1 animal died or was euthanized. Common clinical findings were anorexia, recumbency or weakness, and weight loss or poor growth. Peripheral lymphadenomegaly occurred in only 7 animals and was detected more often at necropsy than during physical examination. Common clinicopathologic abnormalities were hypoalbuminemia, acidosis, azotemia, anemia, hyperglycemia, and neutrophilia. Ultrasonography detected tumors in 4/6 animals. Cytologic evaluation of fluid or tissue aspirates or histopathology of biopsy tissue was diagnostic in 5/6 cases. A clinical course of 2 wk or less prior to death or euthanasia was more common in animals ≤ 2 y of age (9/11) than in older animals (6/13). Regular examination of camelids to include clinical pathology and evaluation of peripheral lymph nodes may result in early detection of MCRT. PMID:21358931

    Objective: To assess the spectrum and clinical relevance of extracoronary findings in coronary CT angiography (CCTA), and to compare a small (cardiac) field of view (FOV) to a large (thoracic) FOV setting. Material and methods: 1084 consecutive patients (mean 57 years) with low-to-intermediate risk of coronary artery disease were enrolled. 542 CCTA scans were interpreted with small FOV (160-190 mm 2 ) encompassing the cardiac region. In another 542 CCTA (patients matched for age and gender), read-out of an additional full FOV (>320 mm 2 ) covering the thorax was performed. Clinical relevance of extracoronary findings was considered as either 'significant' or 'non-significant'. 'Significant' findings were subclassified as either score 1: findings necessitating immediate therapeutic actions, or score 2: findings with undoubted clinical or prognostic relevance, requiring clinical awareness, follow-up or further investigations (non-urgent). 'Non-significant' findings were assigned to either score 3: findings not requiring follow-up or further tests, or as score 4: irrelevant incidental findings. Results: Significantly more patients with extracoronary findings were identified by using a full FOV with 43.2% (234/542) compared to a small FOV with 33.6% (182/542) (p = 0.001). Similarly, a higher total number of extracoronary findings (n = 394) was found on full FOV compared to small FOV (n = 250) (p 2 aortic valve orifice area. Conclusions: The interpretation of extracoronary findings on CCTA scans is mandatory given high prevalence of clinically significant findings by using a full 'thoracic' FOV.

    To assess the frequency, location, associated MR findings, and clinical symptoms of the high level lumbar disc herniation(HLDH). A total of 1076 patients with lunbar disc herniation were retrospectively reviewed. MR images of 41 of these with HLDH(T12-L1, L1-2, L2-3) were analysed in terms of frequency, location, and associated MR findings, and correlated with clinical symptoms of HLDH. The prevalence of HLDH was 3.8%(41/1076). HLDH was located at T12-L1 level in four patients(10%), at L1-2 level in 14(34%), at L2-3 level in 21(51%), and at both L1-2 and L2-3 levels in two. The age of patients ranged from 20 to 72 years (mean, 44), and there were 26 men and 16 women. In 11(27%), whose mean age was 32 years, isolated disc herniation was limited to these high lumbar segments. The remaining 30 patients had HLDH associated with variable involvement of the lower lumbar segments. Associated lesions were as follow : lower level disc herniation(14 patients, 34%); apophyseal ring fracture(8 patients, 19%); Schmorl's node and spondylolisthesis (each 6 patients, each 14%); spondylolysis(3 patients, 7%); and retrolisthesis(2 patients, 5%). In 20 patients(49%) with HLDH(n=41), there was a previous history of trauma. Patients with HLDH showed a relatively high incidence of associated coexisting abnormalities such as lower lumbar disc herniation, apophyseal ring fracture, Schmorl's node, spondylolysis, and retrolisthesis. In about half of all patients with HLDH there was a previous history of trauma. The mean age of patients with isolated HLDH was lower; clinical symptoms of the condition were relatively nonspecific and their incidence was low

    Neuronal ceroid-lipofuscinosis (NCL) is a rare group of inherited neurodegenerative lysosomal storage diseases characterized histopathologically by the abnormal accumulation of ceroid- or lipofuscin-like lipopigments in neurons and other cells throughout the body. The present article describes the clinical, pathologic, and magnetic resonance imaging (MRI) findings of the NCL in three longhaired Chihuahuas between 16 mo and 24 mo of age. Clinical signs, including visual defects and behavioral abnormalities, started between 16 mo and 18 mo of age. Cranial MRI findings in all the dogs were characterized by diffuse severe dilation of the cerebral sulci, dilated fissures of diencephalons, midbrain, and cerebellum, and lateral ventricular enlargement, suggesting atrophy of the forebrain. As the most unusual feature, diffuse meningeal thickening was observed over the entire cerebrum, which was strongly enhanced on contrast T1-weighted images. The dogs' conditions progressed until they each died subsequent to continued neurologic deterioration between 23 mo and 24 mo of age. Histopathologically, there was severe to moderate neuronal cell loss with diffuse astrogliosis throughout the brain. The remaining neuronal cells showed intracytoplasmic accumulation of pale to slightly yellow lipopigments mimicking ceroid or lipofuscin. The thickened meninges consisted of the proliferation of connective tissues with abundant collagen fibers and mild infiltration of inflammatory cells suggesting neuroimmune hyperactivity. Although the etiology of this neuroimmune hyperactivity is not currently known, MRI findings such as meningeal thickening may be a useful diagnostic marker of this variant form of canine NCL.

    Background: The Chiari Malformation I (CMI) is a disorder of uncertain origin that has been traditionally defined as downward herniation of the cerebellar tonsils through the foramen magnum. The anomaly is a leading cause of syringomyelia and occurs in association with osseous abnormalities at the cranio vertebral junction. In contrast to other Chiari malformations, CMI tends to present in the second or third decade of life and is sometimes referred to as the 'adult-type' Chiari malformation. The objective was to document clinical and radiological findings in Arnold Chiari Malformation-I. Method: This was a descriptive study carried out in Ayub Teaching Hospital Abbottabad at Neurosurgery Department during July 2008 - July 2010. We examined a prospective cohort of 60 symptomatic patients. All patients underwent magnetic resonance imaging of the head and spine. Results: There were 40 female and 20 male patients. The age of onset was 24.9 +- 15.8 years. Common associated radiological problems included syringomyelia (60%), scoliosis (25%), and basilar invagination (12%), increased cervical lordosis 5 (8.5%), and Klippel Feil syndrome 2 (3.3%). The most consistent magnetic resonance imaging findings were obliteration of the retrocerebellar cerebrospinal fluid spaces (70% patients), tonsillar herniation of at least 5 mm (100% patients), and varying degrees of post fossa anomalies. Linical manifestations were headaches, pseudotumor-like episodes, a Meniere's disease-like syndrome, lower cranial nerve signs, and spinal cord disturbances in the absence of syringomyelia. Conclusion: These data support accumulating evidence that CMI is a disorder of the para-axial mesoderm that is characterised by underdevelopment of the posterior cranial fossa and overcrowding of the normally developed hindbrain. Tonsillar herniation of less than 5 mm does not exclude the diagnosis. Clinical manifestations of CMI seem to be related to cerebrospinal fluid disturbances (which are responsible

    This study aims to elucidate the frequency, nondetection rate, and clinical importance of incidental extracerebral findings (IECFs) on brain nonenhanced magnetic resonance imaging (MRI). A total of 8284 brain MRIs performed between January 1, 2015 and December 31, 2015 were evaluated for the presence of IECFs and the distribution of IECFs was analyzed. IECFs were categorized as E1 (clinically unimportant, e.g., sinus mucosal thickening); E2 (likely unimportant, e.g., pharyngeal mucosal symmetrical thickening); and E3 (potentially important, e.g., pharyngeal mucosal asymmetrical thickening). The nondetection rate was determined by comparing the results of the structured approach with the initial MRI reports. The medical records were examined for patients with E3 IECFs to assess clinical importance and outcome of these lesions. A total of 5992 IECFs were found in 4469 of the 8284 patients (54.0%). E1 findings constituted 82.2% (4924/5992) of all IECFs; E2 constituted 16.6% (995/5992) and E3 constituted 1.2% (73/5992). Overall IECFs and E1 findings were significantly more common in male patients (P < 0.05). Statistically significant difference was also seen between the different age groups (P < 0.001). The nondetection rate was 56.9% (3409/5992) for overall IECFs and 32.9% (24/73) for E3 IECFs. Of the 73 patients with E3 IECFs, 34 (46.6%) received final diagnosis and appropriate treatment during the study period. IECFs are prevalent in clinical patients on brain MR images with a nondetection rate of 32.9% for potentially important (E3) findings. The reporting of IECFs according to clinical importance is helpful for patients' management. (orig.)

    To analyse MR findings of various involving sites and the relation between such findings and clinical outcome, the authors retrospectively reviewed MR images of acute carbon monoxide intoxication. In 12 patients, MR images obtained from several hours to 12 days after acute carbon monoxide intoxication were reviewed. The images were analysed with regard to involved sites, symmetricity, signal intensity, and the presence or absence of hemorrhage, and the relationship between MR findings and clinical outcome; the presence of delayed encephalopathy was then determined. The globus pallidus(n=9), white matter(n=3), [centrum semiovale(n=2), periventricular white matter(n=1)] and gyrus(n=6) [inferior temporal gyrus(n=2), cingulate gyrus(n=1), precentral gyrus(n=1), hippocampal gyrus(n=1), parahippocampal gyrus(n=1)] were typically involved, and there was also involvenent of the corpus callosum(n=3), thalamus(n=2) and midbrain(n=2). All lesions of the globus pallidus, thalamus, midbrain and temporal lobe were bilaterally symmetric. In all these cases, subtle or prominent low signal intensity was seen on spin-echo T1WI, and high signal intensity on PDWI and T2WI. Some lesions of the globus pallidus(n=1), thalamus(n=1) and midbrain(n=1) were associated with hemorrhage, which occurred during the early subacute stage and was seen on high/low signal intensity T1/T2WI images. Acute cerebral(n=1) and cerebellar(n=1) infarctions were also seen. Cerebral white matter involvement correlated with poor clinical outcome, and in two cases, delayed encephalopathy developed. In these cases of acute carbon monoxide intoxication, the globus pallidus, white matter, cortex and hippocampus were frequently involved, and there was also involvement of various sites such as the corpus callosum, thalamus and midbrain. Lesions of the temporal lobe, thalamus and midbrain were bilaterally symmetric. The involvement of cerebral white matter and the presence of delayed encephalopathy can influence

    To analyze the clinical and chest radiolographic findings of HIV-positive in Pusan survitude. We reviewed the medical records of 74 admission cases of 41 HIV-positive patients (38 mem and 3 women), confirmed in NIH and admitted to our hospital between May 1990 and September 1997. We evaluated the clinical findings including the pulmonary disease diagnosed at each admission, and using the pattern approach assessed the radiographic findings in 63 cases available among 74 admission cases. For statistical analysis the Pearson Chi-Square test was used, and the chest CT findings available in 19 cases among 17 patients were also evaluated. In all cases the mode of transmission was sexual contact, and they were more frequently contacted with foreigners (73%) than koreans (27%). During the follow-up period, pulmonary diseases were diagnosed in 52 (70%) of 74 admission cases. The diagnoses were pneumocystis cabrini pneumonia (PCP, n=15), pneumonia(n=15), pulmonary tuberculosis(n=15), combined infection with PCP and pulmonary tuberculosis(n=5), and combined infection with PCP and bacterial pneumonia(n=1). The count of CD4+ lymphocyte in 33 of 55 available admissions cases was less than 50 cells/mm?. In 28 patients(68%) who died, the time between confirmation of HIV-positive status to death ranged from 2 to 81 (mean, 39) months. Chest radiographs of 46 available admission cases (73%) showed the followingabnormal findings: interstitial opacities(n=26), consolidation(n=17), single or multiple nodules (n=9), hilar or mediastinal lymph node enlargement(n=10), pleural effusion(n=8), cyst(n=2), mass(n=1), and pericardial effusion(n=1). Diffuse ground glass opacity was observed in eight (89%) of nine PCP cases (p<0.05), and in cases of pulmonary tubercolosis, hilar or mediastinal lymph node enlargement was frequent (p<0.05). Pulmonary diseases in HIV-positive patients in Pusan servitude were diagnosed during follow-up in 70% of cases. The majority of these diseases were infectious

    Background: Thrombophlebitis of the internal jugular vein (IJV) secondary to neck infection (so-called Lemierre syndrome) is a rare disease. Purpose: To evaluate the clinical and CT findings in patients with thrombophlebitis of the IJV. Material and Methods: The clinical and contrast-enhanced neck CT findings were retrospective analyzed in 10 patients (eight men, two women; mean age, 62.9±8.3 years) with thrombophlebitis of the IJV. Results: Five patients (50%) had complications, including pneumonia (n = 3), neck abscess (n = 1), and thrombophlebitis of cerebral venous sinus (n = 1). All patients, except two who were lost to follow-up, had improved after antibiotics and anticoagulation therapy. Nine (90%) patients had underlying infectious processes in the neck. Contrast-enhanced neck CT of 12 IJVs (five right, three left, and two bilateral) affected by thrombophlebitis demonstrated > 5 cm in length (n = 8, 67%), ovoid shape (n = 7, 58%), complete occlusion of the lumen (n = 10, 83%), circumferential (n = 11, 92%), smooth (n = 8, 67%), and thick (=4 mm) (n = 8, 67%) rim enhancement, and adjacent soft tissue swelling (n = 11, 92%). Conclusion: Contrast-enhanced CT is useful in the diagnosis of thrombophlebitis of the IJV; characteristic CT findings of this unusual entity may be the main clue to the correct diagnosis

    With increasing use of pediatric cardiovascular MRI, it is important for all imagers to become familiar with the spectrum of non-cardiovascular imaging findings that can be encountered. This study aims to ascertain the prevalence and nature of these findings in pediatric cardiovascular MRIs performed at our institution. We retrospectively evaluated reports of all cardiovascular MRI studies performed at our institute from January 2008 to October 2012 in patients younger than18 years. Most studies (98%) were jointly interpreted by a pediatric cardiologist and a radiologist. We reviewed the electronic medical records of all cases with non-cardiovascular findings, defined as any imaging finding outside the cardiovascular system. Non-cardiovascular findings were classified into significant and non-significant, based on whether they were known at the time of imaging or they required additional workup or a change in management. In 849 consecutive studies (mean age 9.7 ± 6.3 years), 145 non-cardiovascular findings were found in 140 studies (16.5% of total studies). Overall, 51.0% (74/145) of non-cardiovascular findings were in the abdomen, 30.3% (44/145) were in the chest, and 18.6% (27/145) were in the spine. A total of 19 significant non-cardiovascular findings were observed in 19 studies in individual patients (2.2% of total studies, 47% male, mean age 5.9 ± 6.7 years). Significant non-cardiovascular findings included hepatic adenoma, arterially enhancing focal liver lesions, asplenia, solitary kidney, pelvicaliectasis, renal cystic diseases, gastric distention, adrenal hemorrhage, lung hypoplasia, air space disease, bronchial narrowing, pneumomediastinum and retained surgical sponge. Non-cardiovascular findings were seen in 16.5% of cardiovascular MRI studies in children, of which 2.2% were clinically significant findings. Prevalence and nature of these non-cardiovascular findings are different from those reported in adults. Attention to these findings is important

    Objective: To assess the spectrum and clinical relevance of extracoronary findings in coronary CT angiography (CCTA), and to compare a small (cardiac) field of view (FOV) to a large (thoracic) FOV setting. Material and methods: 1084 consecutive patients (mean 57 years) with low-to-intermediate risk of coronary artery disease were enrolled. 542 CCTA scans were interpreted with small FOV (160-190 mm{sup 2}) encompassing the cardiac region. In another 542 CCTA (patients matched for age and gender), read-out of an additional full FOV (>320 mm{sup 2}) covering the thorax was performed. Clinical relevance of extracoronary findings was considered as either 'significant' or 'non-significant'. 'Significant' findings were subclassified as either score 1: findings necessitating immediate therapeutic actions, or score 2: findings with undoubted clinical or prognostic relevance, requiring clinical awareness, follow-up or further investigations (non-urgent). 'Non-significant' findings were assigned to either score 3: findings not requiring follow-up or further tests, or as score 4: irrelevant incidental findings. Results: Significantly more patients with extracoronary findings were identified by using a full FOV with 43.2% (234/542) compared to a small FOV with 33.6% (182/542) (p = 0.001). Similarly, a higher total number of extracoronary findings (n = 394) was found on full FOV compared to small FOV (n = 250) (p < 0.001). The detection rate of clinically significant findings was higher by using full FOV compared to small FOV (25.6% versus 15.4%) (p < 0.001), out of those 2.2% versus 1.8% of findings required immediate actions (score 1), and 23.4% versus 13.6% (p = 0.0001), respectively were of clinical relevance (non-urgent, score 2). The rate of malign findings was 0.2%, and of acute pulmonary embolism 0.1%. More lung pathologies were observed by using full FOV compared to small FOV (22% versus 7%) (p < 0.0001), and the detection rate of

    To correlate clinical findings of Non-bacterial Osteitis (NBO) with whole-body MRI (WB-MRI) findings and determine a radiologic index for NBO (RINBO) which allows standardized reporting of WB-MRI. In a prospective study, 40 patients with diagnosis of NBO underwent clinical examination and WB-MRI in which STIR- and T1- weighted images were assessed for NBO-typical lesions. Parameters of interest for RINBO were: number of radiologically active lesions (RAL), size of the patients' maximum RAL presence of extramedullary and spinal involvement. Results were tested for statistical agreement of clinical and MR-based lesion detection. RINBO was tested for correlation with clinical activity. 62/95 clinically/radiologically active lesions were found in 30/33 patients. In 45 % of the cohort, more active lesions were detected by WB-MRI than by clinical examination. RINBO was a significant predictor for the presence of clinically active lesions. WB-MRI is a powerful diagnostic tool for patients with NBO which can reveal asymptomatic disease activity. With RINBO a standardized evaluation approach is proposed which helps assessing radiologic disease burden and predicts clinical disease activity. (orig.)

    Purpose: To analyze the CT appearances and clinical aspects of the degeneration at atlanto-odontoid(A-O) joint. Methods: Thin section axial CT scans, of AO joints were studied in 317 consecutive patients who underwent brain or cervical spine CT examinations. The images were viewed using double-blind method. Observation included: osteophytosis, changes of joint space and transverse ligament, and the clinical symptoms as well. Results: CT findings of AO joint degeneration included: formation of osteophyte, narrowing of joint space, transverse ligament calcification, and joint vacuum phenomenon. Among individuals above 40 years of age, the incidence of degeneration at AO joint went up gradually (P<0.01). Conclusion: Degeneration of AO joint was not uncommon among aged people, CT could better demonstrate the pathological changes

    Anti-NMDA receptor encephalitis is a paraneoplastic encephalitis characterised by psychiatric features, involuntary movement, and autonomic instability. Various EEG findings in patients with anti-NMDA receptor encephalitis have been reported, however, the correlation between the EEG findings and clinical course of anti-NMDA receptor encephalitis remains unclear. We describe a patient with anti-NMDA receptor encephalitis with a focus on EEG findings, which included: status epilepticus, generalised rhythmic delta activity, excess beta activity, extreme delta brush, and paroxysmal alpha activity upon arousal from sleep, which we term"arousal alpha pattern". Initially, status epilepticus was observed on the EEG when the patient was comatose with conjugate deviation. The EEG then indicated excess beta activity, followed by the emergence of continuous slow activity, including generalised rhythmic delta activity and extreme delta brush, in the most severe phase. Slow activity gradually faded in parallel with clinical amelioration. Excess beta activity persisted, even after the patient became almost independent in daily activities, and finally disappeared with full recovery. In summary, our patient with anti-NMDA receptor encephalitis demonstrated slow activity on the EEG, including extreme delta brush during the most severe phase, which gradually faded in parallel with clinical amelioration, with excess beta activity persisting into the recovery phase.

    Glutathione synthetase (GS) deficiency is a rare inborn error of glutathione (GSH) metabolism manifested by severe metabolic acidosis, hemolytic anemia, neurological problems and massive excretion of pyroglutamic acid (5-oxoproline) in the urine. The disorder has mild, moderate, and severe clinical variants. We aimed to report clinical and laboratory findings of four patients, effect of sodium hydrogen carbonate treatment and long-term follow up of three patients. Urine organic acid analysis was performed with gas chromatography-mass spectrometry. Molecular genetic analysis was performed in three patients, mutation was found in two of them. Enzyme analysis was performed in one patient. Clinical and laboratory findings of four patients were evaluated. One patient died at 4 months old, one patient's growth and development are normal, two patients have developed intellectual disability and seizures in the long term follow up period. Three patients benefited from sodium hydrogen carbonate treatment. The clinical picture varies from patient to patient, so it is difficult to predict the prognosis and the effectiveness of treatment protocols. We reported long term follow up of four patients and demonstrated that sodium hydrogen carbonate is effective for treatment of chronic metabolic acidosis in GS deficieny.

    Despite otological surgerical progress improving clinical congenital ossicular malformation management, some cases remain inadequately treated. We report 27 cases of congenital ossicular malformation, focusing on reasons for remaining or delayed postoperative hearing loss evaluated in 27 congenital ossicular malformation cases in Kyoto Prefecture from 2002 to 2008. Overall success was 93% (25/27) 6 months postoperatively. Two ears had no hearing improvement and three delayed hearing loss 8 to 48 months postoperatively. The first two ears underwent small fenestration stapedotomy with malleus attachment piston, and the other three tympanoplasty type III using an autologous ossicle or total ossicular replacement prosthesis (TORP) as a columella. We discuss problems and solutions using a malleus attachment piston or prosthesis, preoperative audio- and radiological findings, and operative findings including facial nerve anomaly and congenital cholesteatoma.

    There is limited information on the extent and clinical importance of the delay in hospital presentation of acute pulmonary thromboembolism (PTE). The aim of this study was to investigate the delay in hospital presentation of PTE and its association with clinical and imaging findings in PTE. This prospective study was conducted on patients admitted to our hospital with a diagnosis of acute PTE between September 2007 and September 2011. Relationships between delay in hospital presentation and clinical findings, risk factors, imaging findings, and in-hospital mortality were analyzed. Of the 195 patients enrolled, 84 (43.1%) patients presented 3 days after the onset of symptoms. Patients with chest pain, history of immobility for more than 3 days, recent surgery, and estrogen use had significantly less delayed presentation. Right ventricular dysfunction was significantly more frequent in patients with delayed presentation (odds ratio [OR] = 2.38; 95% confidence interval [CI] 1.27-4.44; p = 0.006); however, no relationship was found between delay in presentation and pulmonary computed tomographic angiography or color Doppler sonography findings. Patients with delayed presentation were at higher risk of in-hospital mortality (OR = 4.32; 95% CI 1.12-16.49; p = 0.021). Our study showed that a significant portion of patients with acute PTE had delayed presentation. Also, patients with delayed presentation had worse echocardiographic findings and higher in-hospital mortality. Copyright © 2014 Elsevier Inc. All rights reserved.

    Caring for children with life-limiting conditions places exceptional demands on health professionals. Staff require the optimal skills and expertise necessary to provide the highest quality of care and to achieve this it is essential to understand their learning requirements. The aim is to share the main findings from a Clinical Learning Needs Survey conducted at LauraLynn, currently Ireland's only children's hospice. To date no other Irish service has conducted a formal identification of professional learning and development needs specific to the Irish context. The findings from the study assist workforce planning by providing a glimpse into the immediate study needs of staff working in a children's palliative care setting. The study had two main aims: a) Assist clinical staff within one organisation to identify their own professional learning priorities in children's palliative care and b) Inform the design and delivery of a responsive suite of workshops, programmes and study sessions for children's palliative care. The study identified the key learning needs as end-of-life care, palliative emergencies, communication skill development and bereavement support. These findings are similar to those found internationally and demonstrate the commitment of a new organisation to ensure that specific employee learning requirements are met if the organisation and wider specialty of Irish children's palliative care is to continue its evolution.

    Epidermolysis bullosa acquisita (EBA) is an uncommon, acquired, chronic subepidermal bullous disease. This report describes a case of EBA with gingival involvement. A 43-year-old woman with EBA was referred to our clinic for periodontal therapy because of gingival tenderness and bleeding. She has been on cyclosporin A therapy for the last 2 years. Clinical findings were analyzed. Anterior gingivectomy operations were performed in 2 stages. The samples obtained during the surgery were examined using histopathologic, immunohistologic, and electronmicroscopic methods. Long-term effects of the surgical periodontal treatment on gingiva were evaluated both clinically and microscopically. The dentition displayed minimal enamel hypoplasia. Decayed, missing, and filled surfaces score was found to be elevated. Periodontal examination showed generalized diffuse gingival inflammation and gingival enlargement localized mainly to the anterior region. Nikolsky's sign was positive. However, wound healing was uneventful after the operations. Microscopic findings were similar to those obtained from the skin. Twenty-one months after the operations, Nikolsky's sign was negative and no remarkable gingival inflammation was noted. Microscopic examination revealed that the blisters were fewer in number and smaller in size. These results indicate that gingival tissues may also be involved in EBA. Uneventful wound healing after periodontal surgery in this case suggests that periodontal surgery can be performed in patients with EBA. Moreover, both our clinical and histopathologic findings imply that gingivectomy proves useful in maintaining gingival integrity in these patients. Our data may also suggest that the patients with EBA are highly likely to develop dental caries.

    Solitary rectal ulcer syndrome (SRUS) is a rare disorder often misdiagnosed as a malignant ulcer. Histopathological features of SRUS are characteristic and pathognomonic; nevertheless, the endoscopic and clinical presentations may be confusing. The aim of the present study was to assess the clinical findings, surgical treatment, and outcomes in patients who suffer from SRUS. A retrospective chart review was undertaken, from January 1989 to May 2005 for all patients who were diagnosed with SRUS. Data recorded included: patient's age, gender, clinical presentation, past surgical history, diagnostic and preoperative workup, operative procedure, complications, and outcomes. During the study period, 23 patients were diagnosed with SRUS. Seven patients received only medical treatment, and in three patients, the ulcer healed after medical treatment. Sixteen patients underwent surgical treatment. In four patients, the symptoms persisted after surgery. Two patients presented with postoperative rectal bleeding requiring surgical intervention. Three patients developed late postoperative sexual dysfunction. One patient continued suffering from rectal pain after a colostomy was constructed. Median follow-up was 14 (range 2-84) months. The results of this study show clearly that every patient with SRUS must be assessed individually. Initial treatment should include conservative measures. In patients with refractory symptoms, surgical treatment should be considered. Results of anterior resection and protocolectomy are satisfactory for solitary rectal ulcer.

    To evaluate the MRI findings of acute facial nerve paralysis in Bell's palsy and herpes zoster opticus, and to correlate these with the clinical findings. We retrowspectively reviewed the MRI findings in six cases of BEll's palsy(BP) and two of herpes zoster oticus(HZO), and compared them with the findings for 30 normal facial nerves. This nerve was considered abnormal when its signal intensity was greater than that of brain parenchyma or the contralateral normal side on Gd-enhanced T1-weighted axial and coronal MR images. We analysed the location and degree of contrast enhancement, interval change, and clinical progression in correlation with House-Brackmann(HB) grade and electroneuronography (ENoG) findings. Fifteen of 30 normal facial nerves(50%) seen on Gd-enhanced MRI were mildly enhanced in the geniculate ganglion, the proximal tympanic, and the proximal mastoid segment of the facial nerve. No enhancement of the internal auditory canal(IAC) or labyrinthine segment of the facial nerve was noted, however. In BP and HZO, Gd-enhanced MR images revealed fair to marked enhancement for more than two segments from the internal auditory canal to the mastoid segment of the facial nerve. During follow-up MRI, enhancement of the facial nerve varied in location and signal intensity, though gradually decreased in intensity approximately eight weeks after the onset of facial nerve palsy. No correlation between clinical HB grade, ENoG, and follow up MRI findings was noted. Except in the internal auditory canal and labyrinthine segment, normal facial nevemay show mild and relatively symmetrical enhancement. In BP and HZO, the facial nerve showed diffuse enhancement from the IAC to the mastoid segment.=20.

    Airway-centered Interstitial Fibrosis (ACIF) is a common pathologic pattern observed in our practice. The objectives of this study are to describe the causes associated with ACIF in a large sample of patients and its effect on survival. A retrospective study in three centers of interstitial lung disease in São Paulo, between January of 1995 and December of 2012. The surgical lung biopsy specimens were reviewed by three pathologists. The clinical, functional and tomographic findings were analyzed by a standardized protocol. There were 68 cases of ACIF, most of them women. The mean age was 57 ± 12 yr. Dyspnea, cough, restrictive pattern at spirometry and oxygen desaturation at exercise were common. A reticular pattern with peribronchovascular infiltrates was found in 79% of the cases. The etiologies of ACIF were hypersensitivity pneumonitis in 29 (42.6%), gastroesophageal reflux disease in 17 (25.0%), collagen vascular disease in 4 (5.9%), a combination of them in 15 cases and idiopathic in 3 (4.4%). The median survival was 116 months (95% CI = 58.5 - 173.5). Lower values of oxygen saturation at rest, presence of cough and some histological findings--organizing tissue in the airways, fibroblastic foci and microscopic honeycombing--were predictors of worse survival. ACIF is an interstitial lung disease with a better survival when compared with IPF. The main etiologies are HP and GERD.

    Objective: To explore the typical sonographic features of gray-scale and Power Doppler of acute and chronic gouty arthritis in conjunction with radiographic, clinical, and laboratory findings. Materials and methods: All hand, finger, and toe joints of 19 patients with acute and chronic gout were examined with gray-scale and Power Doppler sonography. The number and size of bone changes detected with sonography was compared to radiographic findings. Vascularization of the synovial tissue was scored on Power Doppler (grades 0-3), and was compared with clinical appearance, including swelling, tenderness, and redness (grades 0-3). Results: In acute gout, mild to moderate echogenic periarticular nodules with sonotransmission and hypervascularization of the edematous surrounding soft tissue were found. In chronic gout, tophaceous nodules completely blocked transmission of US wave, leading to strong reflexion and dorsal shadowing in a minority of cases. No significant difference in the detection of large bone changes (>2 mm) was found between sonography and radiography. However, gray-scale sonography was significantly more sensitive in the detection of small bone changes (p < 0.001). Power Doppler scores were statistically significantly higher than clinical examination scores (p < 0.001). Discussion: Sonography is superior to radiographs in evaluating small bone changes. The inflammatory process in joints can be better detected with Power Doppler sonography than with clinical examination. Typical sonographic appearance of acute and in particular of chronic gout might provide clues on gouty arthritis that adds to the information available from conventional radiography, clinical, and laboratory findings

    To investigate the clinical and electrophysiological features of facial nerve paralysis (FNP) due to benign temporal bone masses (TBMs) and elucidate its differences as compared with Bell's palsy. FNP assessed by the House-Brackmann (HB) grading system and by electroneurography (ENoG) were compared retrospectively. We reviewed 914 patient records and identified 31 patients with FNP due to benign TBMs. Moderate FNP (HB Grades II-IV) was dominant for facial nerve schwannoma (FNS) (n=15), whereas severe FNP (Grades V and VI) was dominant for cholesteatomas (n=8) and hemangiomas (n=3). The average ENoG value was 19.8% for FNS, 15.6% for cholesteatoma, and 0% for hemangioma. Analysis of the correlation between HB grade and ENoG value for FNP due to TBMs and Bell's palsy revealed that given the same ENoG value, the corresponding HB grade was better for FNS, followed by cholesteatoma, and worst in Bell's palsy. Facial nerve damage caused by benign TBMs could depend on the underlying pathology. Facial movement and ENoG values did not correlate when comparing TBMs and Bell's palsy. When the HB grade is found to be unexpectedly better than the ENoG value, TBMs should be included in the differential diagnosis. Copyright © 2017 Elsevier B.V. All rights reserved.

    2002-01-01

    Dementia with lewy bodies (DLB) is the second common degenerative dementia and has several characteristics including fluctuating cognition, visual hallucination and Parkinsonism. We investigated clinical manifestations and neuroimaging findings in DLB patients. Ten probable DLB patients were included in this study. Brain MRI, Tc-99m HMPAO brain perfusion SPECT and I-123 IPT SPECT were performed. All patients were men and mean age of onset was 64.2 years (range from 54 to 80). All had fluctuating cognition and Parkinsonism, and 8 had visual hallucination. Dementia preceded Parkinsonism in 3 patients. Fluctuation of K-MMSE ranges from 3 to 8 points. Rest tremor was seen in 5 patients. Brain MRI showed cortical atrophy in all patients. Tc-99m brain perfusion SPECT showed hypoperfusion in occipital area as well as fronto-temporo-parietal areas. I-123 IPT SPECT revealed reduced uptake comparable to Parkinson's disease in the striatum. DLB should be first considered as one of possible diagnosis in patients showing dementia in the early stage of Parkinsonism. Hypoperfusion in the occipital area was thought to be a characteristic finding in DLB and to be helpful in differentiating DLB from other degenerative dementias

    2001-07-01

    Full Text Available The purpose of this study was to describe the clinical findings in patients with splenic injury and to determine if isolated left lower chest injury may be the single clinical indicator of splenic injury. The medical records of all adult blunt trauma patients with splenic injury over a 14 month period were reviewed. Significant left lower chest injury was considered present if the patient had left sided pleuritic chest pain with tenderness to ribs 7-12 or if these ribs were visualized as fractured on any imaging study. Patients were considered to have clinical findings suggestive of splenic injury if they had pre-hospital or emergency department hypotension, abdominal pain or tenderness, a Glasgow coma scale < 15, or gross hematuria. Ninety patients had splenic injury. Thirty-nine (43%. 95% CI 33, 54% patients had significant left lower chest injury. In five (6%. 95% CI 2, 12% patients, injury to this portion of the chest was the single indicator of splenic injury. Nearly half the patients with splenic injury will have significant injury to the left lower chest and this finding may be the only indicator of splenic injury.

    The aim of the study was to investigate self-experienced nasal symptoms among adults treated for UCLP and the association to clinical findings, and to evaluate whether palate closure in one-stage or two-stages affected the symptoms or clinical findings. All people with UCLP born between 1960-1987, treated at Uppsala University Hospital, were considered for participation in this cross-sectional population study with long-term follow-up. Eighty-three patients (76% participation rate) participated, a mean of 37 years after the first operation. Fifty-two patients were treated with one-stage palate closure and 31 with two-stage palate closure. An age-matched group of 67 non-cleft controls completed the same study protocol, which included a questionnaire regarding nasal symptoms, nasal inspection, anterior rhinoscopy, and nasal endoscopy. Patients reported a higher frequency of nasal symptoms compared with the control group, e.g., nasal obstruction (81% compared with 60%) and mouth breathing (20% compared with 5%). Patients also rated their nasal symptoms as having a more negative impact on their daily life and physical activities than controls. Nasal examination revealed higher frequencies of nasal deformities among patients. No positive correlation was found between nasal symptoms and severity of findings at nasal examination. No differences were identified between patients treated with one-stage and two-stage palate closure regarding symptoms or nasal findings. Adult patients treated for UCLP suffer from more nasal symptoms than controls. However, symptoms are not associated with findings at clinical nasal examination or method of palate closure.

    We wanted to compare the CT findings and clinical features of parotitis and submandibular sialadenitis in children and adults and to evaluate the statistical significance of these in different age groups and the usefulness of a CT scan. Ninety-seven adults and 36 pediatric patients with sialadenitis were included in this retrospective study. Regardless of the site of involvement, we evaluated the CT findings and clinical manifestations between the pediatric and adult groups, and between the pediatric and adult parotitis and submandibular sialadenitis groups. At last, all the patients were classified into seven age groups. Abscess formations were more prominent in the parotitis groups, and sialiths were more common in the submandibular sialadenitis group with the lowest incidence in the young children group (≤ 10 years). Cellulitis seen on a CT scan showed a higher incidence in the adult parotitis group, and this finding was closely connected with pain. A number of patients showed cervical lymphadenitis on a CT scan and this coincided with lymph node palpation. Tonsillitis associated sialadenitis was common in the pediatric group. The therapeutic durations were longer in the pediatric parotitis patient group and the adult submandibular sialadenitis group. CT scans were very helpful to evaluate for abscess, stone, lymphadenitis and estimating the associated clinical manifestations such as swelling, palpable lymph nodes, pain with operation and the therapeutic plan

    The purpose of this study is to correlate CT findings of the patients with chronic subdural hematoma(SDH) showing a sedimentation level with their clinical and operative findings. We selected 9 patients who showed a sedimentation level within the hematoma after reviewing the CT findings of 55 patients with SDH. We also analyzed their age, initial symptoms, cause of head injury, latent period, the level of consciousness on admission, CT findings, and operative findings. All of the 9 patients were aged persons(over 52 years). They had a history of acute exacerbation of neurologic symptoms. Five of them had an apparent history of head trauma more than one month before the exacerbation. The CT scans showed unilateral, crescent-shaped subdural fluid collection with a sedimentation level except a case of bilateral SDH and 2 cases of planoconvex-shaped SDH. The interface of the sedimentation level was sharp in 3 cases and indistinct in 6 cases. None had bleeding tendency and the hemoglobin level was slightly decreased in 2 patients. All patients revealed membrane of the hematoma during operation. The upper portion of the sedimentation was liquefied blood and the lower portion was fresh blood clots. We could observe fresh RBC's in the hematoma microscopically. A sedimentation level in chronic SDH was operatively proved to represent rebleeding, and was clinically manifested as an acute exacerbation of symptoms.

    Objective: To investigate the CT features of pulmonary injury in paraquat poisoning. Methods: The chest CT image of lung injury in 6 cases of paraquat poisoning were analyzed retrospectively. According to different period of poisoning, the 6 cases were divided into 3 types:the early stage of poisoning (within 2 d), the middle stage of poisoning (3-14 d), the late stage of poisoning (>14 d). A comparison between CT signs and the pathological features of patients was made. Results: Among this 6 cases, 3 cases died, 2 cases pulmonary fibrosis was noted, 1 cases recovered. According to different period of poisoning, the 6 cases were divided into 3 stages: in the early stage of poisoning (within 2 d), 3 cases of all patients showed nothing remarkable, 2 cases showed ground-glass opacity, 1 case showed fuzzy lung-marking.In the middle stage of poisoning (3-14 d), all 6 cases showed ground-glass opacity, mosaic attenuation; 6 cases showed pulmonary consolidation; 4 cases showed subpleural lines; 4 cases showed bronchiectasis; 2 cases showed mid-lower pleural effusion. In the late stage of poisoning (>14 d), 4 cases showed pulmonary consolidation and pulmonary fibrosis, 3 cases showed ground-glass opacity and mosaic attenuation, 1 case showed mid-lower pleural effusion; 1 case showed mediastinal emphysema. Conclusion: The clinical pathology process of paraquat poisoning was in line with CT finding which was related with clinical stage and was helpful for clinical assessment of paraquat poisoning promptly and to guide the clinical treatment.

    A 6-month-old miniature Schnauzer presented with hypernatremia and clinical signs of vomiting, diarrhea, inappetence, and lethargy. The dog did not consume water on its own. Hypernatremia and the related clinical signs were resolved by fluid administration. Endocrinological investigations and urinalysis excluded the possibility of diabetes insipidus and hyperaldosteronism. Therefore, the dog was diagnosed with hypodipsic hypernatremia. Magnetic resonance imaging revealed dysgenesis of the corpus callosum and other forebrain structures. On the basis of these findings, congenital brain malformation associated with failure of the osmoreceptor system was suspected. (author)

    The objective of this study was to evaluate the concordance between clinical symptoms, Doppler ultrasound (US), and shunt venography for the detection of stent-graft transjugular intrahepatic portosystemic shunt (TIPS) dysfunction. Forty-one patients (M:F 30:11, median age 55 years) who underwent contemporaneous clinical exam, Doppler US, and TIPS venography between 2003 and 2014 were retrospectively studied. Clinical symptoms (recurrent ascites or variceal bleeding) were dichotomously classified as present/absent, and US and TIPS venograms were categorized in a binary fashion as normal/abnormal. US abnormalities included high/low (>190 or 50 cm/s), absent flow, and return of antegrade intra-hepatic portal flow. Venographic abnormalities included shunt stenosis/occlusion and/or pressure gradient elevation. Clinical and imaging concordance rates were calculated. Fifty-two corresponding US examinations and venograms were assessed. The median time between studies was 3 days. Forty of 52 (77%) patients were symptomatic, 33/52 (64%) US examinations were abnormal, and 20/52 (38%) TIPS venograms were abnormal. Concordance between clinical symptoms and TIPS venography was 48% (25/52), while the agreement between US and shunt venography was 65% (34/52). Clinical symptoms and the US concurred in 60% (31/52) of the patients. The sensitivity of clinical symptoms and US for the detection of venographically abnormal shunts was 80% (16/20) and 85% (17/20), respectively. Both clinical symptoms and the US had low specificity (25%, 8/32 and 50%, 16/32) for venographically abnormal shunts. Clinical findings and the US had low concordance rates with TIPS venography, with acceptable sensitivity but poor specificity. These findings suggest the need for improved noninvasive imaging methods for stent-graft TIPS surveillance.

    Automatic recognition of clinical entities in the narrative text of health records is useful for constructing applications for documentation of patient care, as well as for secondary usage in the form of medical knowledge extraction. There are a number of named entity recognition studies on English clinical text, but less work has been carried out on clinical text in other languages. This study was performed on Swedish health records, and focused on four entities that are highly relevant for constructing a patient overview and for medical hypothesis generation, namely the entities: Disorder, Finding, Pharmaceutical Drug and Body Structure. The study had two aims: to explore how well named entity recognition methods previously applied to English clinical text perform on similar texts written in Swedish; and to evaluate whether it is meaningful to divide the more general category Medical Problem, which has been used in a number of previous studies, into the two more granular entities, Disorder and Finding. Clinical notes from a Swedish internal medicine emergency unit were annotated for the four selected entity categories, and the inter-annotator agreement between two pairs of annotators was measured, resulting in an average F-score of 0.79 for Disorder, 0.66 for Finding, 0.90 for Pharmaceutical Drug and 0.80 for Body Structure. A subset of the developed corpus was thereafter used for finding suitable features for training a conditional random fields model. Finally, a new model was trained on this subset, using the best features and settings, and its ability to generalise to held-out data was evaluated. This final model obtained an F-score of 0.81 for Disorder, 0.69 for Finding, 0.88 for Pharmaceutical Drug, 0.85 for Body Structure and 0.78 for the combined category Disorder+Finding. The obtained results, which are in line with or slightly lower than those for similar studies on English clinical text, many of them conducted using a larger training data set, show that

    To study the outcome of acute otitis media (AOM) with otorrhoea in children managed initially without antibiotics, in relation to bacterial and clinical findings, and to identify those who may benefit from antibiotics. Otherwise healthy, not otitis prone children aged 2-16 y, presenting with AOM with spontaneous otorrhoea, were recruited from primary care and followed at selected ear, nose and throat (ENT) clinics. Specimens for bacterial investigations were obtained; symptoms were registered on a daily basis. The main outcomes measured were the frequency of children treated with antibiotics due to persisting AOM within 9 days in relation to clinical and bacteriological findings, and new AOM within 3 months. Twelve of 71 children who completed the trial received antibiotics during the first 9 days due to lack of improvement. One received antibiotics after 16 days due to relapsing AOM and 6 received antibiotics after 30 days due to new AOM. At 2-4 days following inclusion, over 70% of children showed normalized eardrum status and markedly reduced secretion. Alloiococcus otitidis was found in 23 samples, Streptococcus pneumoniae in 12, Streptococcus pyogenes in 6, and Fusobacterium nucleatum in 5. Mycoplasma pneumoniae, Chlamydia pneumoniae, and Fusobacterium necrophorum were not detected. Antibiotics were prescribed more extensively to children with a pulsating eardrum and abundant purulent secretion. All children with S. pyogenes received antibiotics, whereas children with only A. otitidis did not. The results suggest that antibiotics are indicated in AOM with otorrhoea and the presence of abundant purulent secretion, a pulsating eardrum, or the presence of S. pyogenes. The presence of only A. otitidis was not associated with a more prolonged course or the need for antibiotics.

    From 1974-1980, computerized tomography was carried out on 34 patients with purulent and on 17 patients with lymphocytic meningitis. 25 out of the patients with purulent meningitis resp. meningoencephalitis could be examined in the acute stage. For all patients with already attenuated clinical symptoms normal results were obtained, while for the remainder findings were in part highly pathological consisting, e.g. in dilatations or narviowings of the ventricula system, failure to make the outer liquor cavities roentgenoparens, accumulation of pas in the subarachnoidal and subdur spaces including the interhemispheric clefs, cerebral medulla and periventricular edemas, abscesses and signs of ependymitis. Various findings could only be classified as pathological upon serial examination. Correlation statistics showed that all patients with marked pathological CT findings also suffered from distinct pertubations of consciousness. Out of 14 patients with pathological CT findings, 12 died. No connexions could be established between the level of liquor cell counts and CT alterations. Among 17 patients with a lymphocytic meningitis, CT findings were pathological with a mean dilatation of the ventricular system in only one case of chronic course and predominantly basal localization. The patient decreased. Phathological CT findings in purulent and lymphocytic meningitis point to an unfavourable prognosis. (orig.) [de

    Eight cases of childhood cerebellar ataxia were reported. All these cases showed chronic cerebellar ataxia with early onset, and the other diseases of cerebellum such as infections, neoplasms and storage diseases were excluded by clinical symptoms and laboratory findings including blood counts, blood chemistry, lactate, pyruvate, ceruloplasmine, urinalysis, serum immunoglobulins, amino acid analysis in blood and urine, CSF analysis, leukocyte lysosomal enzymes, MCV, EMG, EEG and brain X-CT. Two pairs of siblings were included in this study. The clinical diagnosis were cerebellar type (5), spinocerebellar type (1), one Marinesco-Sjoegren syndrome and undetermined type (1). The age of onset was 1 to 5 years. The chief complaint was motor developmental delay in 6 cases; among them 5 patients could walk alone at the ages of 2 to 3 years'. Mental retardation was observed in 7 cases and epilepsy in 2. TRH was effective in 5 cases. The MRI study revealed that the area of medial sagittal slice of the cerebellum was reduced significantly in all cases and also that of pons was reduced in 5 cases. Different from typical adult onset spinocerebellar degenerations, most of the present cases have achieved slow developmental milestones and the clinical course was not progressive. Genetic factors are suspected in the pathogenesis of this disease in some cases. (author).

    Clinical cases of hantavirus pulmonary syndrome (HPS) can be challenging to differentiate from other acute respiratory diseases, which can lead to delays in diagnosis, treatment, and disease reporting. Rapid onset of severe disease occurs, at times before diagnostic test results are available. This study's objective was to examine the clinical characteristics of patients that would indicate HPS to aid in detection and reporting. Test results of blood samples from U.S. patients suspected of having HPS submitted to the Centers for Disease Control and Prevention from 1998-2010 were reviewed. Patient information collected by case report forms was compared between HPS-confirmed and test-negative patients. Diagnostic sensitivity, specificity, predictive values, and likelihood ratios were calculated for individual clinical findings and combinations of variables. Of 567 patients included, 36% were HPS-confirmed. Thrombocytopenia, chest x-rays with suggestive signs, and receiving supplemental oxygenation were highly sensitive (>95%), while elevated hematocrit was highly specific (83%) in detecting HPS. Combinations that maximized sensitivity required the presence of thrombocytopenia. Using a national sample of suspect patients, we found that thrombocytopenia was a highly sensitive indicator of HPS and should be included in surveillance definitions for suspected HPS. Using a sensitive suspect case definition to identify potential HPS patients that are confirmed by highly specific diagnostic testing will ensure accurate reporting of this disease.

    The aim of this essay was to demonstrate the normal and pathological CT findings of the post-operative imaging of patients underwent ossicular prosthesis implants. The stapedectomy replaced by prosthesis is considered the 'gold standard' treatment of patients with oval window closure, related to otosclerosis or other inflammatory conditions.

    The aim of this essay was to demonstrate the normal and pathological CT findings of the post-operative imaging of patients underwent ossicular prosthesis implants. The stapedectomy replaced by prosthesis is considered the 'gold standard' treatment of patients with oval window closure, related to otosclerosis or other inflammatory conditions. Several types of prosthesis are available and the choice depends on the extension of the disease or the surgeon's preferences. Based on extensive literature review, the normal postoperative findings, as well as some surgery inherent complications were described, including among others: perforation of the tympanic membrane, necrosis associated with subluxation/extrusion of the prosthesis, granuloma/cholesteatoma or periprosthetic fibrosis, perilymphatic fistula, facial nerve damage, among other.

    Athletic groin pain remains a common field-based team sports time-loss injury. There are few reports of non-surgically managed cohorts with athletic groin pain. To describe clinical presentation/examination, MRI findings and patient-reported outcome (PRO) scores for an athletic groin pain cohort. All patients had a history including demographics, injury duration, sport played and standardised clinical examination. All patients underwent MRI and PRO score to assess recovery. A clinical diagnosis of the injured anatomical structure was made based on these findings. Statistical assessment of the reliability of accepted standard investigations undertaken in making an anatomical diagnosis was performed. 382 consecutive athletic groin pain patients, all male, enrolled. Median time in pain at presentation was (IQR) 36 (16-75) weeks. Most (91%) played field-based ball-sports. Injury to the pubic aponeurosis (PA) 240 (62.8%) was the most common diagnosis. This was followed by injuries to the hip in 81 (21.2%) and adductors in 56 (14.7%) cases. The adductor squeeze test (90° hip flexion) was sensitive (85.4%) but not specific for the pubic aponeurosis and adductor pathology (negative likelihood ratio 1.95). Analysed in series, positive MRI findings and tenderness of the pubic aponeurosis had a 92.8% post-test probability. In this largest cohort of patients with athletic groin pain combining clinical and MRI diagnostics there was a 63% prevalence of PA injury. The adductor squeeze test was sensitive for athletic groin pain, but not specific individual pathologies. MRI improved diagnostic post-test probability. No hernia or incipient hernia was diagnosed.

    Full Text Available Etiological explanations of clinical anxiety can be advanced through understanding the neural mechanisms associated with anxiety in youth prior to the emergence of psychopathology. In this vein, the present study sought to investigate how trait anxiety is related to features of the structural connectome in early adolescence. 40 adolescents (21 female, mean age = 13.49 years underwent a diffusion-weighted imaging scan. We hypothesized that the strength of several a priori defined structural connections would vary with anxious arousal based on previous work in human clinical neuroscience and adult rodent optogenetics. First, connection strength of caudate to rostral middle frontal gyrus was predicted to be anticorrelated with anxious arousal, predicated on extant work in clinically-diagnosed adolescents. Second, connection strength of amygdala to rostral anterior cingulate and to medial orbital frontal cortex would be positively and negatively correlated with anxious arousal, respectively, predicated on rodent optogenetics showing the former pathway is anxiogenic and the latter is anxiolytic. We also predicted that levels of anxiety would not vary with measures of global network topology, based on reported null findings. Results support that anxiety in early adolescence is associated with (1 the clinical biomarker connecting caudate to frontal cortex, and (2 the anxiogenic pathway connecting amygdala to rostral anterior cingulate, both in left but not right hemisphere. Findings support that in early adolescence, anxious arousal may be related to mechanisms that increase anxiogenesis, and not in a deficit in regulatory mechanisms that support anxiolysis.

    Crimean-Congo hemorrhagic fever (CCHF) is a zoonotic disease, which is usually transmitted to humans by tick bites or contact with blood or other infected tissues of livestock. Patients suffering from CCHF demonstrate an extensive spectrum of clinical symptoms. As it can take considerable time from suspecting the disease in hospital until reaching a definitive diagnosis in the laboratory, understanding the clinical symptoms and laboratory findings of CCHF patients is of paramount importance for clinicians. The data were collected from patients who were referred to the Laboratory of Arboviruses and Viral Hemorrhagic Fevers at the Pasteur institute of Iran with a primary diagnosis of CCHF between 1999 and 2012 and were assessed by molecular and serologic tests. Referred patients were divided into two groups: patients with a CCHF positive result and patients with a CCHF negative result. The laboratory and clinical findings of these two groups were then compared. Two-thousand five hundred thirty-six probable cases of CCHF were referred to the laboratory, of which 871 cases (34.3%) were confirmed to be CCHF. Contact with infected humans and animals increased the CCHF infection risk (P important role in patient survival and the application of the findings of this study can prove helpful as a key for early diagnosis. © 2014 Wiley Periodicals, Inc.

    The medical records of 24 cats with histopathologically diagnosed feline infectious peritonitis involving the nervous system were reviewed. Seventeen cats had historical, clinical, and pathological findings of systemic disease. Twelve cats had focal signs of central nervous system dysfunction. Twelve cats had multifocal signs including seizures, nystagmus, head tilt, vestibular or cerebellar ataxia, paresis, and proprioceptive loss with a preponderance of caudal fossa signs. Computed tomography of the brain revealed hydrocephalus in two cats. Examination of cerebrospinal fluid revealed pyogranulomatous pleocytosis in fivecats; the tap was nonproductive in five cats. Findings on histopathological examination of appropriate tissues included nephritis, hepatitis, and pleuritis. Neuropathological findings included ependymitis, choroid plexitis, meningitis, encephalitis, and myelitis. Hydrocephalus was seen in 18 cats on necropsy

    Full Text Available Objectives: The objective of this study was to evaluate the concordance between clinical symptoms, Doppler ultrasound (US, and shunt venography for the detection of stent-graft transjugular intrahepatic portosystemic shunt (TIPS dysfunction. Materials and Methods: Forty-one patients (M:F 30:11, median age 55 years who underwent contemporaneous clinical exam, Doppler US, and TIPS venography between 2003 and 2014 were retrospectively studied. Clinical symptoms (recurrent ascites or variceal bleeding were dichotomously classified as present/absent, and US and TIPS venograms were categorized in a binary fashion as normal/abnormal. US abnormalities included high/low (>190 or 50 cm/s, absent flow, and return of antegrade intra-hepatic portal flow. Venographic abnormalities included shunt stenosis/occlusion and/or pressure gradient elevation. Clinical and imaging concordance rates were calculated. Results: Fifty-two corresponding US examinations and venograms were assessed. The median time between studies was 3 days. Forty of 52 (77% patients were symptomatic, 33/52 (64% US examinations were abnormal, and 20/52 (38% TIPS venograms were abnormal. Concordance between clinical symptoms and TIPS venography was 48% (25/52, while the agreement between US and shunt venography was 65% (34/52. Clinical symptoms and the US concurred in 60% (31/52 of the patients. The sensitivity of clinical symptoms and US for the detection of venographically abnormal shunts was 80% (16/20 and 85% (17/20, respectively. Both clinical symptoms and the US had low specificity (25%, 8/32 and 50%, 16/32 for venographically abnormal shunts. Conclusion: Clinical findings and the US had low concordance rates with TIPS venography, with acceptable sensitivity but poor specificity. These findings suggest the need for improved noninvasive imaging methods for stent-graft TIPS surveillance.

    2007-02-01

    Full Text Available Abstract Background Atypical scrapie is a recently recognised form of transmissible spongiform encephalopathy of sheep that differs from classical scrapie in its neuropathological and biochemical features. Most cases are detected in apparently healthy sheep and information on the clinical presentation is limited. Case presentation This report describes the clinical findings in two sheep notified as scrapie suspects and confirmed as atypical scrapie cases by immunohistochemistry and Western immunoblotting. Although both sheep displayed signs suggestive of a cerebellar dysfunction there was considerable variation in the individual clinical signs, which were similar to classical scrapie. Conclusion Any sheep presenting with neurological gait deficits should be assessed more closely for other behavioural, neurological and physical signs associated with scrapie and their presence should lead to the suspicion of scrapie.

    To analyze CT and follow-up chest radiographic findings in patients with necrotizing pneumonia and to evaluate clinical significance of the extent of necrosis. We reviewed medical records and retrospectively analysed CT scans and follow-up chest radiographs of 22 patients with necrotizing pneumonia, confirmed by biopsy (n = 7) and culture (n = 15). Inclusion criteria for necrotizing pneumonia was necrotic low attenuation, with or without cavitation on postcontrast enhanced CT scan. The study group included 15 men and seven women, aged 11-66 years (average: 47 years). The pathogens of necrotizing pneumonia were Klebsiella spp (n = 7), Enterobacter spp (n = 5), Actinomyces spp (n = 4), Pseudomonas spp (n = 4), Nocardia spp (n = 4), and others (n = 5). Average duration of pneumonia was 4.1 months. On CT scan, pneumonic consolidations were well-marginated in 14 patients and there were cavities on initial CT scan in 16 cases. Margins of the necrotic portion on CT scan were well-demarcated in majority of the patients (16/22). Low attenuation areas on initial CT scan resulted in cavitation, fibrosis and volume loss as shown on follow-up chest radiographs. The larger the necrotic areas on CT, the more the volume loss was. CT findings of necrotizing pneumonia were well-marginated air-space consolidation with low attenuation area, with or without cavity. The extent of necrotic area was closely related with the degree of fibrotic change later on. CT is important tool for diagnosis and prediction of parenchymal damage in necrotizing pneumonia

    Purpose: To describe the magnetic resonance (MR) appearance and associated clinical findings of partial distal biceps tendon tears. Design: Twenty elbow MR images at 1.5 T, performed over a 7 year period, were reviewed for an appearance of partial tears in the distal biceps. These images were assessed by two musculoskeletal radiologists for the extent of: (a) abnormal signal intensity within the tendon, and the presence of (b) bicipitoradial bursitis, and (c) bony microavulsive injury of the radial tuberosity. Medical records for nine of the 20 cases were reviewed for the clinical findings of ecchymosis, trauma, sensation of a ''pop'', loss of function, and acuity of onset. Results: Twenty partial distal biceps tendon tears were seen. All displayed an abnormally increased signal in the distal biceps tendon. Three of 20 (15%) showed a 25% to 50% tear, ten of 20 (50%) showed a 50% tear, and seven of 20 (35%) showed a 75% to 90% tear. Bicipitoradial bursitis was seen in 11 of 20 (55%) cases. Bony microavulsive injury of the radial tuberosity was observed in 10 of 20 (50%). Of the nine cases reviewed for associated clinical findings, surprisingly, only three (33%) experienced an acute traumatic episode with an abrupt onset of pain. An insidious onset was reported in four of nine (44%). Sensation of a ''pop'' was recorded in only two of nine (22%) cases. Ecchymosis and loss of function were not seen in any of the cases. Finally, surgical conformation was obtained for three cases. Conclusion: Partial distal biceps tendon tears have a characteristic MR appearance, demonstrate little functional deficit, and may be attritional in their etiology due to the observation of a low number of patients reporting trauma or an acute onset.

    Manometry is the gold-standard diagnostic test for motility disorders in the esophagus. The development of high-resolution manometry catheters and software displays of manometry recordings in color-coded pressure plots have changed the diagnostic assessment of esophageal disease. The diagnostic value of particular esophageal clinical symptoms among patients suspected of esophageal motor disorders (EMDs) is still unknown. The aim of this study was to explore the sensitivity, specificity, and predictive accuracy of presenting esophageal symptoms between abnormal and normal esophageal manometry findings. We conducted a cross-sectional study of 623 patients aged 11-80 years. Data were collected from clinical examinations as well as patient questionnaires. The sensitivity, specificity, and accuracy were calculated after high-resolution manometry plots were reviewed according to the most recent Chicago Criteria. The clinical symptoms were not sensitive enough to discriminate between EMDs. Nevertheless, dysphagia, noncardiac chest pain, hoarseness, vomiting, and weight loss had high specificity and high accuracy to distinguish EMDs from normal findings. Regurgitation and heartburn did not have good accuracy for the diagnosis of EMDs. Clinical symptoms are not reliable enough to discriminate between EMDs. Clinical symptoms can, however, discriminate between normal findings and EMDs, especially achalasia.

    Mycoplasma Pneumonia is a cause of primary atypical pneumonia, but it is asymptomatic mostly or may cause of only mild symptoms. School-aged children experienced high attack rate and manifestation if 'unusual pneumonia' are noted. So authors reviewed clinical and radiological features of 110 cases of serologically proven Mycoplasma pneumonia in hospitalized children between November 1984 and January 1987 retrospectively. The results were as follows ; 1. The sex distribution was 57:53 (1.1:1) in male to female ratio and 47% of them were 5 though 8 years old of age with peak incidence between 5 and 6 years old of age. 2. The symptoms were cough, fever, and sore throat in descending order of frequency and mean symptom duration before admission was 8.1 day. The prevalent season was earlier winter. 3. The radiologic findings were air-space consolidation with lobar, segmental distribution in 68%, interstitial infiltration in 12%, bronchopneumonia in 12%, chronic bronchitis pattern in 3.6%, normal in 4.5%, hilar LN enlargement in 37%, pleural effusion in 12%. 4. Radiologic resolution period was usually 10 days around (4-25 days) and after complete recovery, scarring change or calcification was not seen. 5. Extrapulmonary manifestations were uncommon but hepatitis, hematuria, skin rash, gastroenteritis, myocarditis, otitis media occurred. 6. With administration of tetracyclin and erythromycin, clinical and radiologic responses were promptly seen.

    The aim of this study was to characterize the imaging features and compare computed tomography (CT) findings with clinical features of patients with Streptococcus pneumoniae pneumonia. We retrospectively reviewed 75 patients (44 men, 31 women; mean age 67 years) diagnosed with S. pneumoniae pneumonia who underwent chest CT scanning at our institution between January 2007 and August 2008. Diagnoses were based on detection of the S. pneumoniae antigen in urine. Chest CT scans revealed abnormalities in all patients. The predominant opacity patterns were an airspace pneumonia pattern (48%) and a bronchopneumonia pattern (48%), followed by an interstitial pneumonia pattern (4%). Consolidation was observed most frequently (84%) followed by ground glass opacity (82.7%), bronchial wall thickening (61.3%), and centrilobular nodules (49.3%). Airway dilatation (21.6%), pleural effusion (33.3%), lymphadenopathy (34.8%), and pulmonary emphysema (21.3%) were also observed. Pulmonary emphysema was significantly less frequent in patients with the bronchopneumonia pattern than in those without (p=0.007). The clinical features and CT findings did not differ significantly. CT image analysis showed that patients with S. pneumoniae pneumonia exhibited the bronchopneumonia and airspace pneumonia patterns with equal frequency. Bronchopneumonia pattern was less common in patients with preexisting emphysema. (author)

    To determine the characteristics of femoral condyle insufficiency fracture (FCIF) lesions and their relative associations with the risk of clinical progression. This HIPAA-compliant retrospective study was approved by our Institutional Review Board. Seventy-three patients (age range, 19-95) were included after excluding patients with post-traumatic fractures, bone marrow infarct, osteochondritis dissecans, or underlying tumor. Two board-certified musculoskeletal radiologists classified morphologic findings including lesion diameter, associated bone marrow edema pattern, and associated cartilage/meniscus damage. Electronic medical charts were evaluated for symptoms, risk factors, and longitudinal outcomes, including total knee arthroplasty (TKA). Imaging characteristics were correlated with clinical findings, and comparison of outcome groups was performed using a regression model adjusted for age. The majority of patients with FCIF were women (64.4 %, 47/73), on average 10 years older than men (66.28 ± 15.86 years vs. 56.54 ± 10.39 years, p = 0.005). The most common location for FCIF was the central weight-bearing surface of the medial femoral condyle; overlying full thickness cartilage loss (75.7 %, 53/70) and ipsilateral meniscal injury (94.1 %, 64/68) were frequently associated. Clinical outcomes were variable, with 23.9 % (11/46) requiring TKA. Cartilage WORMS score, adjacent cartilage loss, and contralateral meniscal injury, in addition to decreased knee range of motion at presentation, were significantly associated with progression to TKA (p < 0.05). FCIF are frequently associated with overlying cartilage loss and ipsilateral meniscal injury. The extent of cartilage loss and meniscal damage, in addition to loss of knee range of motion at the time of presentation, are significantly associated with clinical progression. (orig.)

    Full Text Available Benzene is a ubiquitous environmental pollutant and an important industrial chemical present in both gasoline and motor vehicle emissions. Occupational human exposure to benzene occurs in the petrochemical and petroleum refining industries as well as in gas-station workers, where it can lead to benzene poisoning (BP, but the mechanisms of BP are not completely understood. In Brazil, a significant number of gas-station service workers are employed. The aim of the present study was to evaluate alterations related to BP and metabolic polymorphisms in gas-station service workers exposed to benzene in the city of Rio de Janeiro, Brazil. Occupational exposure was based on clinical findings related to BP, and metabolic polymorphisms in 114 Brazilian gas-station attendants. These workers were divided into No Clinical Findings (NCF and Clinical Findings (CF groups. Neutrophil and Mean Corpuscular Volume (MCV showed a significant difference between the two study groups, and neutrophil has the greatest impact on the alterations suggestive of BP. The clinical findings revealed higher frequencies of symptoms in the CF group, although not all members presented statistical significance. The frequencies of alleles related to risk were higher in the CF group for GSTM1, GSTT1, CYP2E1 7632T > A, but lower for NQO1 and CYP2E1 1053C > T genotypes. Moreover, an association was found between GSTM1 null and alterations related to BP, but we did not observe any effects of other polymorphisms. Variations in benzene metabolizing genes may modify benzene toxicity and should be taken into consideration during risk assessment evaluations.

    Objective: To present the prevalence, clinical, and imaging findings of interruption or congenital stenotic lesions of the inferior vena cava (IVC), associated malformations, and their clinical relevance. Materials and methods: Between March 2004 and March 2006, 7972 patients who had undergone consecutive routine abdominal multidetector row computed tomography were analyzed for interruption or stenotic lesion of the IVC. Results: Prevalence of interruption (n = 8) or congenital stenosis (n = 4) of the IVC occurred in 12 (0.15%) of 7972 patients. Four patients with interruption and four patients with congenital stenosis of the IVC were symptomatic with DVT (n = 4), leg swelling (n = 4), leg pain (n = 2), lower extremity varices (n = 2), hepatic vein thrombosis (n = 1), and hematochezia (n = 1). All four of the asymptomatic patients were from the interruption group, and these patients had interrupted IVC with well-developed azygos/hemiazygos continuation. Eight symptomatic patients did not have a well-developed azygos/hemiazygos continuation, and drainage of lower extremity was mainly from collateral veins. Additional findings in eight symptomatic patients were abdominal venous collaterals (n = 8), venous aneurysm (n = 2), lower extremity varices (n = 2), varicocele (n = 2), and pelvic varices (n = 1). Conclusion: Interruption or stenosis of the IVC are rare on routine abdominal CT examinations and may cause different clinical findings depending on the variant drainage patterns or collaterals. Interrupted IVC is commonly asymptomatic if associated with well-developed azygos/hemiazygos continuation, whereas commonly symptomatic if well-developed azygos/hemiazygos continuation is not present

    We aimed to determine clinical, laboratory and demographical characteristics of tularemia on admission to Emergency Department (ED). Medical data of 317 patients admitted to ED and subsequently hospitalized with suspected tularemia between January 1, 2011, and May 31, 2015, were collected. Patients were divided into 2 groups according to microagglutination test results, as tularemia (+) and tularemia (-). Of the 317 patients involved, 49 were found to be tularemia (+) and 268 were tularemia (-). Mean age of the tularemia (+) patients was found to be higher than that of tularemia (-) patients. When compared to tularemia (-) patients, a significant portion of patients in tularemia (+) patients were elderly, living in rural areas and had contact with rodents. When clinical and laboratory findings of the 2 groups were compared, any statistical significance could not be determined. Tularemia is a disease of elderly people living in rural areas. Contact with rodents also increases risk of tularemia in suspected patients. Copyright © 2015 Elsevier Inc. All rights reserved.

  15. Clinical Findings Documenting Cellular and Molecular Abnormalities of Glia in Depressive Disorders

    Directory of Open Access Journals (Sweden)

    2018-02-01

    Full Text Available Depressive disorders are complex, multifactorial mental disorders with unknown neurobiology. Numerous theories aim to explain the pathophysiology. According to the “gliocentric theory”, glial abnormalities are responsible for the development of the disease. The aim of this review article is to summarize the rapidly growing number of cellular and molecular evidences indicating disturbed glial functioning in depressive disorders. We focus here exclusively on the clinical studies and present the in vivo neuroimaging findings together with the postmortem molecular and histopathological data. Postmortem studies demonstrate glial cell loss while the in vivo imaging data reveal disturbed glial functioning and altered white matter microstructure. Molecular studies report on altered gene expression of glial specific genes. In sum, the clinical findings provide ample evidences on glial pathology and demonstrate that all major glial cell types are affected. However, we still lack convincing theories explaining how the glial abnormalities develop and how exactly contribute to the emotional and cognitive disturbances. Abnormal astrocytic functioning may lead to disturbed metabolism affecting ion homeostasis and glutamate clearance, which in turn, affect synaptic communication. Abnormal oligodendrocyte functioning may disrupt the connectivity of neuronal networks, while microglial activation indicates neuroinflammatory processes. These cellular changes may relate to each other or they may indicate different endophenotypes. A theory has been put forward that the stress-induced inflammation—mediated by microglial activation—triggers a cascade of events leading to damaged astrocytes and oligodendroglia and consequently to their dysfunctions. The clinical data support the “gliocentric” theory, but future research should clarify whether these glial changes are truly the cause or simply the consequences of this devastating disorder.

    To determine the optimal clinical and CT findings for differentiating Kikuchi's disease (KD) and tuberculous lymphadenitis (TB) in patients presenting with cervical lymphadenopathy. From 2006 to 2010, 87 consecutive patients who were finally diagnosed with KD or TB were enrolled. Two radiologists performed independent analysis of contrast-enhanced neck CT images with regard to the involvement pattern, nodal or perinodal changes, and evidence of the previous infection. Significant clinical and CT findings of KD were determined by statistical analyses. Of the 87 patients, 27 (31%) were classified as having KD and 60 (69%) as having TB. Statistically significant findings of KD patients were younger age, presence of fever, involvement of ≥5 nodal levels or the bilateral neck, no or minimal nodal necrosis, marked perinodal infiltration, and no evidence of upper lung lesion or mediastinal lymphadenopathy. The presence of four or more statistically significant clinical and CT findings of KD had the largest area under the receiver-operating characteristic curve (A z = 0.861; 95% confidence intervals 0.801, 0.909), with a sensitivity of 89% and specificity of 83%. CT can be a helpful tool for differentiating KD from TB, especially when it is combined with the clinical findings.

    To review the clinical and diagnostic findings and survival of dilated cardiomyopathy from a large population of dogs in England. A retrospective study of the case records of dogs with dilated cardiomyopathy collected between January 1993 and May 2006. There were 369 dogs with dilated cardiomyopathy of which all were pure-bred dogs except for four. The most commonly affected breeds were dobermanns and boxers. Over 95 per cent of dogs weighed more than 15 kg and 73 per cent were male. The median duration of signs before referral was three weeks with 65 per cent presenting in stage 3 heart failure. The most common signs were breathlessness (67 per cent) and coughing (64 per cent). The majority of dogs (89 per cent) had an arrhythmia at presentation and 74 per cent of dogs had radiographic signs of pulmonary oedema or pleural effusion. The median survival time was 19 weeks. Dilated cardiomyopathy occurs primarily in medium to large breed pure-bred dogs, and males are more frequently affected than females. The duration of clinical signs before referral is often short and the survival times are poor. Greater awareness of affected breeds, clinical signs and diagnostic findings may help in early recognition of this disease which often has a short clinical phase.

    The extent to which participants act to clinically verify research results is largely unknown. This study examined whether participants who received Lynch syndrome (LS)-related findings pursued researchers' recommendation to clinically verify results with testing performed by a CLIA-certified laboratory. The Fred Hutchinson Cancer Research Center site of the multinational Colon Cancer Family Registry offered non-CLIA individual genetic research results to select registry participants (cases and their enrolled relatives) from 2011 to 2013. Participants who elected to receive results were counseled on the importance of verifying results at a CLIA-certified laboratory. Twenty-six (76.5%) of the 34 participants who received genetic results completed 2- and 12-month postdisclosure surveys; 42.3% of these (11/26) participated in a semistructured follow-up interview. Within 12 months of result disclosure, only 4 (15.4%) of 26 participants reported having verified their results in a CLIA-certified laboratory; of these four cases, all research and clinical results were concordant. Reasons for pursuing clinical verification included acting on the recommendation of the research team and informing future clinical care. Those who did not verify results cited lack of insurance coverage and limited perceived personal benefit of clinical verification as reasons for inaction. These findings suggest researchers will need to address barriers to seeking clinical verification in order to ensure that the intended benefits of returning genetic research results are realized. © 2017 The Authors.

    Bone marrow abnormalities (BMAs) are frequently found in osteoarthritis (OA) of the knee with magnetic resonance imaging (MRI). Some reports have suggested BMA was correlated with the X-ray stage of OA and also with knee pain, but the reports depended on two-dimensional images without considering the spatial expansion of BMAs. To determine whether three-dimensional expansion of a BMA with MRI in patient with medial-type OA of the knee is correlated with the radiographic stage of OA and clinical findings using a semi-quantitative method. Cross-sectional study. This study enrolled 238 patients with medial-type OA. Radiography and MRI of the knee were taken in all participants. X-rays were graded using the Kellgren-Lawrence (K/L) grade (1-4). T2-weighted fat-suppressed MRI images were used to score the size of the BMA according to the whole-organ MRI score (WORMS). A new scoring system defined as the spatial BMA score (s-score), which specifically addressed the spatial expansion of BMAs, was examined to assess the size of the BMA. BMA frequency was examined in subdivisions of the articular surfaces of the knee according to the X-ray stages of the K/L grade and the correlation of the s-score to the clinical findings. BMA frequency in the medial femorotibial joint (MFTJ; 74%) was significantly higher than in the lateral femorotibial joint (LFTJ; 14%) and patellofemoral joint (PFJ; 14%; P<0.01). The s-score of the MFTJ was strongly correlated with the X-ray stage assessed by the K/L grade. The s-score of the MFTJ was also correlated with the clinical findings. The frequency and spatial expansion of BMAs in the MFTJ are strongly correlated with the X-ray stage of medial-type OA as well as the clinical findings. (author)

    Nailfold capillaroscopy is an important tool for the diagnosis and follow-up of patients with rheumatic diseases, in particular dermatomyositis and scleroderma. A relationship has been observed in adults between improved capillaroscopic findings and reduced disease activity. Our aim was to correlate disease activity (clinical and laboratory data) and nailfold capillaroscopy findings in 18 patients with inflammatory myopathies. This prospective study included 13 juvenile dermatomyositis patients (Bohan and Peter criteria) (mean age of 8.8 years) and five patients with overlap syndrome (mean age of 15.7 years). We evaluated disease activity (skin abnormalities and muscle weakness, muscle enzymes and acute phase reactants) and its correlation with nailfold capillaroscopy findings (dilatation of isolated loops, dropout of surrounding vessels and giant capillary loops). We used a microscope with special light and magnification of 10 to 16X. Eighteen patients underwent a total of 26 capillaroscopic examinations, seven of them on two or more occasions (13 were performed during the active disease phase and 13 during remission). Twelve of the 13 examinations performed during the active phase exhibited scleroderma pattern and 8 of the 13 examinations performed during remission were normal. Therefore, in 20 of the 26 examinations clinical and laboratory data and nailfold capillaroscopy findings correlated (p = 0.01). Nailfold capillaroscopy is a non-invasive examination that offers satisfactory correlation with disease activity and could be a useful tool for the diagnosis and follow-up of inflammatory myopathies.

    Purpose: To analyze MR imaging and clinical findings associated with ganglia of the tarsal sinus. Materials and methods: In a record search, ganglia of the tarsal sinus were retrospectively identified in 26 patients (mean age 48 ± 16 years), who underwent MR imaging for chronic ankle pain. Images were reviewed by two radiologists in consensus for size and location of ganglia, lesions of ligaments of the ankle and the tarsal sinus, tendon abnormalities, osteoarthritis, osseous erosions and bone marrow abnormalities. Medical records were reviewed for patient history and clinical findings. Results: Ganglia were associated with the interosseus ligament in 81%, the cervical ligament in 31% and the retinacula in 46% of cases. Signal alterations suggesting degeneration were found in 85%, 50% and 63% in case of the interosseus ligament, the cervical ligament and the retinacula, respectively. Scarring of the anterior talofibular ligament and the fibulocalcaneal ligament was found in 68% and 72% of the patients, respectively, while only 27% of the patients recalled ankle sprains. Ganglia at the retinacula were highly associated with synovitis and tendinosis of the posterior tibial tendon (p < 0.05). Conclusion: All patients with ganglia in the tarsal sinus presented with another pathology at the ankle, suggesting that degeneration of the tarsal sinus may be a secondary phenomenon, due to pathologic biomechanics at another site of the hind foot. Thus, in patients with degenerative changes of the tarsal sinus, one should be alerted and search for underlying pathology, which may be injury of the lateral collateral ligaments in up to 70%.

    Full Text Available Besides magnetic resonance imaging, the presence of locally produced oligoclonal IgG bands (OCB in the cerebrospinal fluid (CSF is the most consistent laboratory abnormality in patients with multiple sclerosis (MS. The most sensitive method for the detection of CSF OCB is isoelectric focusing (IEF [6]. Occasional patients with clinically definite MS lack evidence for intrathecal IgG synthesis [7, 8]. This study was designed to compare clinical data and evoked potential (EP findings between CSF OCB positive and OCB negative MS patients. The study comprised 22 OCB negative patients with clinically definite MS [11] and 22 OCB positive controls matched for age, disease duration, activity and course of MS. In both groups clinical assessment was performed by using Expanded Disability Status Scale (EDSS score [12] and progression rate (PR. All patients underwent multimodal EP: visual (VEPs, brainstem auditory (BAEPs and median somatosensory (mSEPs. The VEPa were considered abnormal if the P100 latency exceeded 117 ms or inter-ocular difference greater than 8 ms was detected. The BAEPs were considered abnormal if waves III or V were absent or the interpeak latencies I-III, III-V, or I-V were increased. The mSEPs were considerd abnormal when N9, N13 and N20 potentials were absent or when increased interpeak latencies were recorded. The severity of the neurophysiological abnormalities was scored for each modality as follows normal EP score 0; every other EP abnormality except the absence of one of the main waves, score 1; absence of one or more of the main waves, score 2 [13]. Both mean EDSS score (4.0 vs. 3.5 and PR (0.6 vs. 0.5 were similar in OCB positive and OCB negative group, (p>0.05. In the first group males were predominant, but without statistical significance (Table 1. Disease started more often with the brainstem symptoms in the OCB positive than in OCB negative MS group (p=0.028, while there was no differences in other initial symptoms between

    The X-ray findings in temporal bone anomalies are reviewed. Radiological procedure and examination technique are presented, as are symptoms of important anomalies. The methods available are plain film X-ray of temporal bone, multi-directional tomography, and high-resolution CT. Although some of the abnormalities are visible even in plain films, consistent use of conventional tomography or CT is necessary for correct diagnosis. This procedure is indicated not only when an abnormality is clinically obvious, but also in all cases of unexplained hearing loss without evidence of acquired disease. The advantage of CT over conventional tomography is that soft tissue anomalies, such as primary cholesteatoma or tumor simulating vascular abnormalities, can be demonstrated. In these cases CT is obligatory. (orig.) [de

    We analyzed thin-section CT, pathological, and clinical findings of peripheral lung squamous cell carcinomas, with diameters of less than 20 mm and compared these findings with solid type adenocarcinomas. CT findings of polygonal shapes, notches, pleural thickness, and cavities are more frequently found in squamous cell carcinomas than in adenocarcinomas. The pathological types can be classified in two groups: Solid types, Scirrhous types. The 5 year survival rate after resection is 64.5%, which is poorer than survival rate for solid type adenocarcinomas. It is vital to diagnose and treat peripheral squamous cell carcinomas as early as possible. (author)

    The objective of this observational study is to describe clinical, haematological and serum biochemical findings of horses affected with alfalfa dodder (Cuscuta campestris) toxicity. Twenty horses naturally exposed to alfalfa dodder toxicity were examined and information was collected on history and clinical signs. Physical examination was done on horses in the premises (n=20), and venous blood samples of 12 horses were submitted for haematology and serum biochemical examination for each horse. Abnormal clinical signs started around 36 hours after horses were fed the contaminated alfalfa. Abnormal signs were seen in 11 horses and those included diarrhoea (n=8), decreased appetite (n=7), neurological signs (n=4) and abdominal pain (n=1). Some horses had multiple clinical signs of the above. The results of complete blood cell count revealed leukocytopenia, neutropenia and thrombocytopenia. Serum biochemical analysis revealed decreased ALP, AST and CPK levels and increased direct bilirubin level. The used alfalfa was stopped immediately and a different alfalfa from a new container that did not contain any weeds was fed. Horses on the premises were observed closely, and the abnormal clinical signs resolved within three days. No treatment was implemented. Knowledge about toxicity of horses by Cuscuta species is scarce in the English veterinary literature and very limited.

    This study analyses clinical data, EEC and X-ray findings of 102 stationary examined migraine patients, 62 of whom suffered from migraine accompagnee. Sex distribution, age at onset of disease, hereditary disease disposition and EEC findings largely correspond to the data given in literature. As it had been expected, the X-ray images of the skull and the cerebral angiographies performed in 46 patients suffering from migraine accompagnee did not show any pathological findings. The X-ray images were compared with those taken of patients without migraine anamnesis in order to detect non-pathologic variations. Neither differences in the intensity of vascular and diplovenous marking could be found in the native images of the skull nor any variations of the circle of Willis. The dependency of the posterior cerebral artery on the carotid circulation existing in 41% of the migraine accompagnee does not lead to any particular alteration of the accompanying symptoms and signs. The idea is discussed to divide the migraine syndrome into simple, focal and complicated migraine on the basis of a uniform pathogenesis. (orig./MG).

    Full Text Available This study was carried out to describe the ultrasonographic findings in relation to the clinical symptoms of some common ocular conditions in sheep and goats. Fifty animals (32 goats and 18 sheep with different ocular problems were examined. Ultrasonographic examination was performed using a B-mode ocular ultrasound unit, and the structure of the globe was evaluated at a depth of 4-6 cm. Early cases (n=35, 70% showed varying ocular conditions; hypopyon, (n=8, 16%, stromal abscesses, (n=4, 8%, and anterior uveitis (n=23, 46%. Hypopyon appeared clinically as a white or yellowish material in the anterior chamber, and ultrasonographically as a hyperechoic mass in the anterior chamber. Severe iridocyclitis was noticed in acute cases of infectious keratoconjunctivitis (IKC accompanied by blepharospasm, photophobia, excessive tearing and eyelid margin crust formation. Ultrasonographically, the pupil appeared constricted with increased hyperechoic thickening of the ciliary body. In chronic cases of IKC, corneal pigmentation (n=5, 10% and cataract (n=10, 20% were seen. Ultrasonographically the type and degree of cataract were diagnosed. The present study provides an inside view of the inner ocular structures during the course of certain eye diseases where ophthalmoscopic examination is not possible. Our findings, although preliminary, are relevant for the more complete diagnosis of certain external ocular conditions in sheep and goat herds.

    To correlate scintigraphic and clinical findings of the metatarsophalangeal joint (MTPJ) in Standardbreds, radiographic findings in horses with confirmed MTPJ lameness, and determine if stress reaction and more advanced bone remodelling occurred in the MTPJ, medical records of 114 Standardbreds admitted between September 1993 and April 1995 in which bone scintigraphy included standing lateral and plantar views of the metatarsophalangeal joint (MTPJ) were reviewed. Images obtained using a large field of view gamma camera were evaluated visually for location, definition and intensity of increased radioisotope uptake (IRU), which was graded as mild, moderate, or intense. Clinical history and lameness examination findings were recorded and, in horses with documented MTPJ lameness, radiographic examination included the 30 degree (down-angled) dorsolateral 45 degree plantaromedial view thought to be useful in evaluation of the plantarolateral condyle of the third metatarsal bone (MtIII). The most common abnormality, IRU of the plantarolateral aspect of MtIII, was seen in 67 horses, and horses were further classified according to scintigraphic and clinical findings. In 43 horses in which lameness was not localised to the MTPJ, mild (32 horses), moderate (10 horses), and intense (one horse) IRU of MtHII was found. In 24 horses with lameness localised to the MTPJ, moderate (18 horses) and intense (6 horses) IRU was found. Of 18 horses with moderate IRU of MtIII, 9 had radiographic evidence of abnormal bony remodelling of MtIII, whereas 5 of 6 horses with intense IRU had radiographic changes. In 12 horses with MTPJ lameness and radiographic evidence of bony remodelling without fracture, radiographic changes consisted of plantarolateral subchondral radiolucency and sclerosis (7 horses), radiolucency and osteochondrosis (one horse), and plantar MtIII sclerosis without radiolucency (4 horses). In 2 horses with moderate IRU and MTPJ lameness, radiographic evidence of

    To characterize clinical signs and histologic findings in dogs with odontogenic cysts and determine whether histologic findings were associated with clinical features. Retrospective case series. 41 dogs. Medical records were reviewed to obtain clinical data, including breed, age, sex, and lesion location. Microscopic sections and results of diagnostic imaging were reviewed. Odontogenic cysts were identified in 41 dogs between 1995 and 2010. There were 29 dogs with dentigerous cysts, 1 with a radicular cyst, 1 with a lateral periodontal cyst, and 1 with a gingival inclusion cyst. In addition, 9 dogs with odontogenic cysts that had clinical and histologic features suggestive of, but not diagnostic for, odontogenic keratocysts seen in people were identified. In all 9 dogs, these cysts were located in the maxilla and surrounded the roots of normally erupted teeth. Of the 29 dogs with dentigerous cysts, 23 had a single cyst, 5 had 2 cysts, and 1 had 3 cysts. Six cysts were associated with an unerupted canine tooth, and 30 were associated with an unerupted first premolar tooth (1 cyst was associated both with an unerupted canine tooth and with an unerupted first premolar tooth). Dentigerous cysts were identified in a variety of breeds, but several brachycephalic breeds were overrepresented, compared with the hospital population during the study period. Results suggested that a variety of odontogenic cysts can occur in dogs. In addition, cysts that resembled odontogenic keratocysts reported in people were identified. We propose the term canine odontogenic parakeratinized cyst for this condition.

I argue that the one-sided framing of psychological research on political ideology has limited our understanding of the personality correlates of liberalism and conservatism.

  13. Corpus callosum and neglect syndrome: Clinical findings after meningioma removal and anatomical review

    Full Text Available Two types of neglect are described: hemispatial and motivational neglect syndromes. Neglect syndrome is a neurophysiologic condition characterized by a malfunction in one hemisphere of the brain, resulting in contralateral hemispatial neglect in the absence of sensory loss and the right parietal lobe lesion being the most common anatomical site leading to it. In motivational neglect, the less emotional input is considered from the neglected side where anterior cingulate cortex harbors the most frequent lesions. Nevertheless, there are reports of injuries in the corpus callosum (CC causing hemispatial neglect syndrome, particularly located in the splenium. It is essential for a neurosurgeon to recognize this clinical syndrome as it can be either a primary manifestation of neurosurgical pathology (tumor, vascular lesion or as a postoperative iatrogenic clinical finding. The authors report a postoperative hemispatial neglect syndrome after a falcotentorial meningioma removal that recovered 10 months after surgery and performs a clinical, anatomical, and histological review centered in CC as key agent in neglect syndrome.

    Among the variable manifestating conditions of neuronal migration disorders, mental retardation, motor disturbance and epilepsy are the main features of developmental disabilities. We analyzed the relationship between clinical symptoms and magnetic resonance (MR) images, including surface anatomy scan (SAS). Thirty-nine patients (23 males, 16 females; mean age 6.1 years) with neuronal migration disorders were studied. The diagnoses were cerebral palsy in 23 cases, mental retardation in 4, West syndrome in 4, Fukuyama type congenital muscular dystrophy (FCMD) in 6, Walker-Warburg syndrome in 1 and Dubowitz syndrome in 1. Cortical dysplasias were classified into the following 7 groups, mainly based on the SAS findings: complete agyria (AG 1), mixture of agyria and pachygyria (AG 2), bilateral complete pachygyria (BP 1), diffuse pachygyria with marked widening of the bilateral superior frontal gyrus (BP 2), unilateral pachygyria with hemispheric atrophy or hemimegalencephaly (UP), focal cortical dysplasia (FP) and other findings such as solitary schizencephaly (Others). Most cases of AG 1 and AG 2 showed spastic quadriplegia (6/7) and symptomatic generalized epilepsy (5/7), whereas cases of BP 1 showed spasticity only in 1/8 and epilepsy in 7/8. Hemiplegia was observed in 6/7 of UP, 2/8 of FP and 2/4 of Others. Partial epilepsy was observed in 2/7 of UP and 1/8 of FP. Intellectual level was variable in BP 1, UP, FP and Others, but all cases showed severe mental retardation in AG 1, AG 2 and BP 2. BP 2 was observed in all cases of typical FCMD (5/5). The birth weight was less than 2,500 g in 6/7 of UP. The structural findings well correlated with clinical symptoms and epileptic seizure types. The surface anatomy scan was a very useful technique for detecting cortical dysplasias. (author)

    Fabry disease is a complex pathology, requiring a multidisciplinar approach both in the diagnostic workout and in the management of therapy. Clinical criteria able to predict its morbidity have not yet been found. The wide variability of clinical signs and symptoms requires an individual approach based on the single patient, in order to achieve an optimal management. Enzyme replacement therapy (ERT) has been introduced in the clinical setting for over ten years, but its ability to change the course of the disease has not yet been clearly proved. Recently the hypothesis that ERT may be ineffective in patients with severe organ involvement has emerged. The clinical course of Fabry disease is usually slower in eterozygous women than emizygous men, but can be frequently associated to severe organ failure and premature death in both cases. In this review we discuss the histological aspects of Fabry nephropathy in relation to diagnosis, prognosis, therapy and its effectiveness.

    Background. The aim of this study was to describe the clinical, mammographical and pathological characteristics of inflammatory carcinoma. Patients and methods. Clinical, mammographical and histological sections of twenty-two women (age range 28-60 years) were reviewed. The examinations had been performed over a period of four years. Results. The clinical findings were: erythema, edema, thickening of the skin and breast heat in ten patients; palpable mass in nine patients; nipple discharge in one patient; absent in two patients. Pathological findings were: tumor emboli in the dermal lymphatics in eight patients; tumor emboli in the vessels in ten patients; tumor emboli both in the dermal lymphatics and in the vessels in four patients. The radiologic findings were: skin thickening, trabecular thickening and blurring of structure in ten patients (common presentation); mass in nine patients; malignant-type calcifications in two patients (uncommon presentation); absent in one patient. The follow-up examination (eighteen months) detected that only one patient with common presentation of inflammatory carcinoma had no local or systemic recurrence against eight patients with uncommon presentation. Conclusions. The clinical and mammographical aspects, which suggest the presence of an inflammatory carcinoma, occur only in 45.4% of the patients. The radiological aspect seems to correlate with the different prognosis of the tumour, resulting in a better prognosis in those with an uncommon aspect. (author)

    We evaluated long-term magnetic resonance imaging (MRI) features of Knee Osteochondral Autologous Transplantation (OAT)-Mosaicplasty and correlated MRI findings and clinical outcome. Twenty-four patients (mean age 29.9 ± 8.7, 70.8% male) undergoing arthroscopic OAT between 1997 and 2000 were prospectively enrolled. The International Cartilage Repair Society (ICRS)/International Knee Documentation Committee (IKDC) scores and Tegner scores were employed for clinical evaluation. The magnetic resonance observation of cartilage repair tissue (MOCART) was utilized for description and assessment of the repair tissue. Median follow up was 113 months (interquartile range [IQR] 106-122). MRI showed good survival of grafted cartilage in 62.5% of patients. The integration of the graft was complete in 75% of cases, while the repaired tissue was intact in 62.5% and had an homogeneous structure in 70.8%. The MOCART score significantly correlated with objective and subjective scores (p = 0.003 and p = 0.002). Contrastingly, overall MOCART showed no correlation with the Tegner score. MRI revealed to be a powerful tool for non-invasive long-term assessment of OAT.

    Gadolinium-enhanced magnetic resonance imaging (Gd-MRI) is often performed in the evaluation of patients with persistent sciatica after lumbar disc surgery. However, correlation between enhancement and clinical findings is debated, and limited data are available regarding the reliability of enhancement findings. To evaluate the reliability of Gd-MRI findings and their correlation with clinical findings in patients with sciatica. Prospective observational evaluation of patients who were enrolled in a randomized trial with 1-year follow-up. Patients with 6- to 12-week sciatica, who participated in a multicentre randomized clinical trial comparing an early surgery strategy with prolonged conservative care with surgery if needed. In total 204 patients underwent Gd-MRI at baseline and after 1 year. Patients were assessed by means of the Roland Disability Questionnaire (RDQ) for sciatica, visual analog scale (VAS) for leg pain, and patient-reported perceived recovery at 1 year. Kappa coefficients were used to assess interobserver reliability. In total, 204 patients underwent Gd-MRI at baseline and after 1 year. Magnetic resonance imaging findings were correlated to the outcome measures using the Mann-Whitney U test for continuous data and Fisher exact tests for categorical data. Poor-to-moderate agreement was observed regarding Gd enhancement of the herniated disc and compressed nerve root (kappa0.95). Of the 59 patients with an enhancing herniated disc at 1 year, 86% reported recovery compared with 100% of the 12 patients with nonenhancing herniated discs (p=.34). Of the 12 patients with enhancement of the most affected nerve root at 1 year, 83% reported recovery compared with 85% of the 192 patients with no enhancement (p=.69). Patients with and without enhancing herniated discs or nerve roots at 1 year reported comparable outcomes on RDQ and VAS-leg pain. Reliability of Gd-MRI findings was poor-to-moderate and no correlation was observed between enhancement and

    The objective of this study was to evaluate the impact of clinical TMJ diagnosis, gender, and age on the agreement between expected and actual radiographic findings. A total of 204 patients with TMJ symptoms were examined using the Research Diagnostic Criteria (RDC/TMD). Expected radiographic findings were recorded. TMJ tomograms in closed and open mouth position were assessed for osseous changes and condyle position. Expected and actual findings were compared. Logistic regression analyses were performed with agreement on radiographic findings as the dependent variable and with clinical RDC/TMD diagnoses, gender and age as the independent variables. The number of radiographic findings was mostly underestimated. A clinical diagnosis of osteoarthritis and age increased the chance of overestimating osseous changes. Disc displacement and age decreased the chance of agreement on certain condyle positions. Tomography often revealed unexpected findings. It was not possible to select particular patient groups who would benefit more or less from a radiographic examination.

    Headache is recognized as the main but unwarranted symptom of subarachnoid hemorrhage (SAH). There are no enough findings identified as predictive for headache occurrence in SAH. We evaluated the clinical and paraclinical factors predictive for headache occurrence in SAH. We retrospectively analyzed medical records of 431 consecutive non traumatic SAH patients (264 females and 167 males), ages from 19 to 91 years, presenting with headache (70.3%) and without headache (29.7%) during period of 11years. Among all tested parameters, as negative predictors for headache occurrence were recognized: patients' ages (OR 0.97 [95%CI: 0.96-0.99], p=0.025), persistence of coagulation abnormality (OR 0.23 [95%CI: 0.08-0.67], p=0.006), atrial fibrilation (OR 0.23 [95%CI: 0.09-0.59], p=0.002), chronic renal failure (OR 0.26 [95%CI: 0.09-0.76], p=0.014) and more diseases (OR 0.11 [95%CI: 0.04-0.32], p<0.0001), as higher clinical score (OR 0.94 [95%CI: 0.90-0.99], p=0.018) including positive neurological findings (OR 0.34 [95%CI: 0.21-0.55], p<0.001) and loss of consciousness (OR 0.22 [95%CI: 0.12-0.39], p<0.001) at the SAH onset, while the complaint of neck stiffness was identified as its positive predictor (OR 1.93 [95%CI: 1.19-3.10], p=0.007). Although diagnosis based solely on clinical presentation is not reliable and speculative, our findings could provide physicians with evidence to consider SAH not only in conditions of its headache occurrence but also in those with headache absence.

    Bowel and/or mesentery injuries represent the third most common injury among patients with blunt abdominal trauma. Delayed diagnosis increases morbidity and mortality. The aim of our study was to evaluate the role of clinical signs along with CT findings as predictors of early surgical repair. Between March 2014 and February 2017, charts and CT scans of consecutive patients treated for blunt abdominal trauma in two different trauma centers were reread by two experienced radiologists. We included all adult patients who underwent contrast-enhanced CT of the abdomen and pelvis with CT findings of blunt bowel and/or mesenteric injury (BBMI). We divided CT findings into two groups: the first included three highly specific CT signs and the second included six less specific CT signs indicated as "minor CT findings." The presence of abdominal guarding and/or abdominal pain was considered as "clinical signs." Reference standards included surgically proven BBMI and clinical follow-up. Association was evaluated by the chi-square test. A logistic regression model was used to estimate odds ratio (OR) and confidence intervals (CI). Thirty-four (4.1%) out of 831 patients who sustained blunt abdominal trauma had BBMI at CT. Twenty-one out of thirty-four patients (61.8%) underwent surgical repair; the remaining 13 were treated conservatively. Free fluid had a significant statistical association with surgery (p = 0.0044). The presence of three or more minor CT findings was statistically associated with surgery (OR = 8.1; 95% CI, 1.2-53.7). Abdominal guarding along with bowel wall discontinuity and extraluminal air had the highest positive predictive value (100 and 83.3%, respectively). In patients without solid organ injury (SOI), the presence of free fluid along with abdominal guarding and three or more "minor CT findings" is a significant predictor of early surgical repair. The association of bowel wall discontinuity with extraluminal air warrants exploratory laparotomy.

    To characterize clinical, imaging, and sialendoscopy findings in patients with chronic parotitis and multiple parotid calcifications. Retrospective review. Clinical history, radiographic images and reports, lab tests, and operative reports were reviewed for adult patients with chronic parotitis and multiple parotid calcifications who underwent parotid sialendoscopy. Thirteen of 133 (10%) patients undergoing parotid sialendoscopy for chronic sialadenitis had more than one calcification in the region of the parotid gland. Seven patients (54%) were diagnosed with immune-mediated disease from autoimmune parotitis (positive Sjögren's antibodies or antinuclear antibodies) or human immunodeficiency virus (HIV) disease. The six patients (46%) who did not have an immune-mediated disorder had most calcifications located anterior or along the masseter muscle. Eight of 13 patients (61%) had at least one calculus found in the parotid duct on sialendoscopy. Four patients (38%) had multiple punctate calcifications within the parotid gland, all of whom had either autoimmune parotitis or HIV. None of the proximal or punctate parotid calcifications posterior to the masseter were visualized on sialendoscopy. Chronic parotitis in conjunction with multiple parotid calcifications is uncommon and was identified in 10% of our cohort. We contrast two classifications of parotid calcifications: 1) intraductal stones that cause recurrent duct obstruction and are often located within the main parotid duct along or anterior to the masseter and 2) punctate intraparenchymal parotid gland calcifications that are not visualized on sialendoscopy and may represent underlying inflammatory disease. 4 Laryngoscope, 127:1565-1570, 2017. © 2016 The American Laryngological, Rhinological and Otological Society, Inc.

    To characterize the ultrasonographic and clinical findings of inguinal hernia containing the ovary or omentum in girls. We studied 46 girls (49 cases) who were diagnosed with inguinal hernia on ultrasonography between March 2009 and December 2015. The ultrasonographic findings were retrospectively analyzed with respect to location, age at detection, contents of hernia, diameter of the canal of Nuck, and incidence of reducibility, incarceration and strangulation. The clinical findings included the number of cases that underwent operation, contents of hernia discovered during operation, and duration between ultrasonographic diagnosis and operation. The two groups in which inguinal hernia contained the ovary and omentum were statistically compared. Of the 49 cases, the contents of hernia were the ovary or tube in 14 cases, omentum in 32 cases, and bowel in 3 cases. The ovarian herniation group was significantly younger (10.1 months vs. 4.9 years, p < 0.001), had a lower incidence of reducibility (n = 3 vs. n = 29, p < 0.001), higher incidence of incarceration (n = 4 vs. n = 0, p = 0.006), and a shorter duration between ultrasonographic diagnosis and operation (5.7 days vs. 55.8 days, p = 0.032) than the omental herniation group. The ovarian herniation group was younger, had a lower incidence of reducibility, higher incidence of incarceration, and a shorter duration between ultrasonographic diagnosis and operation.

    Aim: To characterize the frequency of identification, clinical importance, and concordance in interpretation of incidental abdominopelvic findings identified on routine lumbar spinal MRI using supplemental expanded field-of-view (FOV) coronal imaging. Materials and methods: All lumbar spinal MRI reports over a 12-month period were retrospectively reviewed for the presence of incidental abdominopelvic findings identified using expanded FOV coronal imaging. Medical records were used to identify those findings that received follow-up, which were then categorized according to final diagnosis and classified as “indeterminate,” “likely clinically unimportant,” and “likely clinically important”. All cases that received follow-up were blindly and independently re-reviewed by a neuroimaging radiologist and body-imaging radiologist, and reviewer performances were compared to assess for agreement with regard to lesion significance, need for follow-up, and other parameters. Results: In total, 2067 reports were reviewed: 687 (33.2%) featured one or more incidental abdominopelvic findings, and 102 (4.9%) findings received further evaluation. Of these, 11 (10.9%) were classified as “indeterminate,” 50 (49%) as “likely clinically unimportant,” and 41 (40.1%) were classified as “likely clinically important.” Excellent agreement was observed between the reviewing radiologists for all evaluated parameters. Conclusion: The addition of an expanded FOV coronal sequence to the standard lumbar spinal MRI protocol was associated with the identification of a large number of incidental abdominopelvic findings, the minority of which represent likely clinically important findings. Most incidental findings were confidently dismissed by a neuroimaging radiologist as likely clinically unimportant without utilization of additional clinical or radiographic resources. - Highlights: • Expanded field-of-view (FOV) MRI improves detection of important incidental findings.

    Aim : The aim of the present study was to determine the occurrence of furcation involvement in the molars of patients with chronic periodontitis and correlate clinical and radiographic findings. Seventy subjects aged 35-69 years enrolled for treatment at a periodontics specialization program in Pernambuco, Brazil (EAP-SCDP-ABO/PE) participated in the study, comprising a total of 350 molars examined. The clinical diagnosis of furcation involvement was performed with a horizontal Nabers probe, whereas the radiographic examination was performed with periapical and bite-wing radiographs. The images were analyzed with an X-ray viewer at 3× magnification. The Chi-square test was used, with the level of significance set at 5%. A total of 64.5% individuals presented with furcation involvement, 43.1% of whom had degree II furcation. A significant association (P = 0.0060) was found between tooth type and frequency of furcation involvement. The first lower and upper molars were affected in 64.5 and 58.5% of cases, respectively. Adequate agreement (0.65) was observed between the clinical and radiographic findings. Taking into consideration the method employed and the results obtained, it may be concluded that the clinical and radiographic examinations performed are effective tools for diagnosing furcation involvement in teeth affected with periodontal disease.

    Scrub typhus is an infectious disease caused by Orientia tsutsugamushi-induced systemic vasculitis, but the involvement of the gastrointestinal tract and the endoscopic findings associated with scrub typhus are not well understood. We performed a prospective study and recommend performing esophagogastroduodenoscopy (EGD) for all possible scrub typhus patients, regardless of gastrointestinal symptoms. Gastrointestinal symptoms, endoscopic findings and clinical severity based on organ involvement and ICU admission were analyzed. Gastrointestinal symptoms occurred in up to 76.4% of scrub typhus patients. The major endoscopic findings were ulcers (43/127, 33.9%). Interestingly, 7.1% (9/127) of the patients presented with esophageal candidiasis. There was no correlation between the presence or absence of gastrointestinal symptoms and the endoscopic grade (P = 0.995). However, there was a positive correlation between the clinical severity and the endoscopic findings (P = 0.001). Sixty-three percent of the patients presented with erosion or ulcers on prospectively performed endoscopic evaluations, irrespective of gastrointestinal symptoms. Gastrointestinal symptoms did not reflect the need for endoscopy. Scrub typhus patients could have significant endoscopic abnormalities even in the absence of gastrointestinal symptoms.

    ABSTRACT Background Identifying PD‐specific biomarkers in biofluids will greatly aid in diagnosis, monitoring progression, and therapeutic interventions. PD biomarkers have been limited by poor discriminatory power, partly driven by heterogeneity of the disease, variability of collection protocols, and focus on de novo, unmedicated patients. Thus, a platform for biomarker discovery and validation in well‐characterized, clinically typical, moderate to advanced PD cohorts is critically needed. Methods BioFIND (Fox Investigation for New Discovery of Biomarkers in Parkinson's Disease) is a cross‐sectional, multicenter biomarker study that established a repository of clinical data, blood, DNA, RNA, CSF, saliva, and urine samples from 118 moderate to advanced PD and 88 healthy control subjects. Inclusion criteria were designed to maximize diagnostic specificity by selecting participants with clinically typical PD symptoms, and clinical data and biospecimen collection utilized standardized procedures to minimize variability across sites. Results We present the study methodology and data on the cohort's clinical characteristics. Motor scores and biospecimen samples including plasma are available for practically defined off and on states and thus enable testing the effects of PD medications on biomarkers. Other biospecimens are available from off state PD assessments and from controls. Conclusion Our cohort provides a valuable resource for biomarker discovery and validation in PD. Clinical data and biospecimens, available through The Michael J. Fox Foundation for Parkinson's Research and the National Institute of Neurological Disorders and Stroke, can serve as a platform for discovering biomarkers in clinically typical PD and comparisons across PD's broad and heterogeneous spectrum. © 2016 The Authors.

    Full Text Available Purpose: Posterior reversible encephalopathy syndrome (PRES is associated with a range of medical conditions and medications. In this retrospective analysis, we present 19 pediatric patients with PRES who had undergone chemotherapy. Methods: We identified four female and 15 male patients diagnosed with PRES on the basis of clinical and radiologic features. Patient charts were reviewed from January 2013 to June 2016 after authorization from the institutional review board. Results: The average age of patients with PRES was 7 years. Primary diagnoses were non-Hodgkin lymphoma (n = 9, acute pre–B-cell leukemia (n = 5, relapsed pre–B-cell leukemia (n = 2, Hodgkin lymphoma (n = 2, and Ewing sarcoma (n = 1. PRES occurred during induction chemotherapy in 12 patients. Sixteen patients had hypertension when they developed PRES. Most of these patients (n = 13 were receiving corticosteroids on diagnosis of PRES. Common clinical features were hypertension, seizures, and altered mental status. With the exclusion of three patients, all others required antiepileptic therapy. Ten of these patients underwent additional magnetic resonance imaging. Ten patients are still alive. Conclusion: In patients who presented to our center with signs and symptoms of hypertension, seizures, visual loss, or altered mental status, PRES was mostly seen in those who were undergoing systemic and intrathecal chemotherapy. Approximately 40% of the patients had reversal of clinical and radiologic findings. Antiepileptic medications were discontinued after being seizure free for approximately 6 months.

    Precise anatomical understanding of orbital blow-out fracture lesions is necessary for the treatment of patients. Retrospectively, MRI findings were compared with the clinical features of pure type blow-out fractures and the efficacy of MRI in influencing a decision for surgical intervention was evaluated. Eighteen child (15 boys, 3 girls) cases were evaluated and compared with adult cases. The patients were classified into three categories (Fig.1) and two types (Fig.2) in accordance with the degree of protrusion of fat tissue. The degree of muscle protrusion also was divided into three categories (Fig. 3). Both muscle and fat tissue were protruding from the fracture site in 14 cases. Fat tissue protrusion alone was found in 3 cases. In contrast, no protrusion was seen in one case. The incarcerated type of fat prolapse was found in 40% of cases, while muscle tissue prolapse was found in 75% of patients. Marginal irregularity or swelling of muscle was observed in 11 patients. There was good correlation of ocular motor disturbance and MRI findings. Disturbance of eyeball movement was observed in all patients with either incarcerated fat tissue or marginal irregularity or swelling of muscle. In contrast, restriction of eyeball movement was rare in cases of no incarceration, even if the fracture was wide. Deformity or marginal irregularity of the ocular muscle demonstrated in MRI may suggest damage an adhesion to the muscle wall. When MRI reveals incarceration or severe prolapse of fat tissue, or deformity and marginal irregularity of the ocular muscle, surgical intervention should be considered. (author)

    Full Text Available Background: Hypothyroidism is a clinical condition associated with low levels of thyroid hormones with raised TSH. Peripheral neuropathy may be associated with hypothyroidism which usually develops insidiously over a long period of time due to irregular taking of drugs or lack of thyroid hormone replacement. Objectives: The present study was done to evaluate the clinical and electro-physiological findings in hypothyroid patients in order to evaluate the neuromuscular dysfunction as well as motor neuropathy. Method: In this study, 70 subjects with the age range from 20 to 50 years of both sexes were included of whom 40 hypothyroids were taken in study group (B with the duration of 6 months to 5 years and 30 healthy euthyroid subjects were taken as control (Group A. On the basis of their TSH level, group B was further divided into group B1 with TSH level <60 MIU /L (less severe and group B2 with TSH >60 MIU /L (severe group. The d latency and NCV for motor nerve function were measured by NCV machine in median and ulnar nerve for upper limb and in common peroneal nerve for lower limb. TT3, TT4 were measured by RIA and TSH by IRMA method. All these parameters were measured on the day 1 (one of their first visit. Data were analysed statistically by ANOVA and Z test. Result: Both TT3, TT4 levels were significantly (P<0.01 lower in hypothyroids in comparison to those of control. Diminished or absence of most of the deep tendon reflexes were found in all the hypothyroids. Most of the patients (67.5% showed significantly higher (P <0.01 motor distal latencies (MDL with lower (P> 0.001 conduction velocities (MNCV and all these changes were more marked in group B2. Conclusion: So, the study revealed that motor neuropathy may be a consequence of hypothyroidism.DOI: 10.3329/bsmmuj.v1i1.3692 Key Words: Hypothyroidism; neuropathy; electrophysiology BSMMU J 2008; 1(1: 15-18

    Eight patients with small intestinal rupture due to blunt abdominal trauma were analyzed by their clinical findings and diagnostic imaging (plain film, ultrasound and computed tomography). Computed tomography was most useful for identification of intraabdominal extraluminal free air (pneumoperitoneum) and this finding was obtained in seven out of the eight patients (87.5 %). Intraabdominal fluid collection was observed in All the patients and was most clearly detectable by ultrasound and computed tomography. These examinations may be applied to identification of properties of the fluid collection. All the patients eventually developed peritonitis when laparotomy was decided. Thus, close follow up observation of abdominal physical signs was also of critical importance. (author)

    We analyzed the sonograms of 6 cases with uterine synechiae in pregnancy. The diagnosis was based on the clinical and sonographic findings. Previous curret age during the artificial abortion and/or after the spontaneous abortion had been done in 5 cases (83.3%). In all cases, uterine synechia in pregnancy was recognized asintra-amniotic sheet containing hypoechoic central zone and an hyperechoic outer layers. Y-shaped splitting of thehyperechoic outer layers was seen against the uterine wall. The placenta extended along the sheet in 4 cases. Uterine synechiae in pregnancy should be distinguished from amniotic band syndrome by the characteristic snographic findings, and unwarranted abortion of normal fetus should be avoided

    Clinics that receive Title X funding have a mandate to encourage parent-child communication for minors seeking family planning services. Little is known about the programs and practices that clinics have adopted to achieve this goal, or whether clinics not receiving Title X funds encourage family participation. As part of a larger project examining parental engagement among adolescents using family planning clinics, 81 clinics that served 200 or more adolescent contraceptive clients in 2001 completed a questionnaire containing closed- and open-ended items. Topic areas included clinic counseling and policies regarding clients younger than 18, activities to improve parent-child communication and community relations. Frequency distributions were calculated for the prevalence of activities, and cross-tabulations were used to compare prevalence by clinic characteristics. Every clinic engaged in at least one activity to promote parent-child communication, and nine in 10 offered multiple activities. Most of the clinics used counseling sessions to talk to adolescent clients about the importance of discussing sexual health issues with parents (73-94%, depending on the reason for the visit). More than eight in 10 clinics (84%) distributed pamphlets on how to talk about these issues. A substantial minority (43%) offered or referred interested individuals to educational programs designed to improve communication. Some of these exploratory findings reflect the prevalence of activities among all U.S. family planning clinics that serve adolescent clients. Evaluation and expansion of clinic efforts to promote voluntary communication about sexual health issues between parents and children could help encourage family participation.

    To determine the association of gallbladder (GB) abnormalities on ultrasonography (US) of patients with acute hepatitis A with demographic, clinical, and biochemical factors, and with other US findings. This retrospective study was approved by our institutional review board, which waived the requirement for informed consent. We retrospectively evaluated 152 consecutive patients with acute hepatitis A who underwent US. The diagnosis of acute hepatitis A was made during acute illness by demonstrating anti- HAV of the IgM class. US images were reviewed simultaneously by two abdominal radiologists and a consensus was reached for GB wall thickening, GB collapse, lymphadenopathy, and hepatic echogenicity. The associations between demographic, clinical, biochemical, and US findings and GB wall thickening or collapse were then assessed. GB wall thickening was present in 123 (81%) and GB collapse in 96 (63%) of the 152 patients. Total bilirubin level and GB collapse differed significantly (p < 0.05) between patients with and without GB wall thickening. Gender ratio, total and peak total bilirubin level, and GB wall thickness differed significantly (p < 0.05) between patients with and without GB collapse. Multivariate analysis showed that GB wall thickening was associated with GB collapse and vice versa. GB wall thickening and GB collapse are common US abnormalities associated with each other in patients with acute hepatitis A. However, GB wall thickening or collapse is not associated with any demographic, clinical, or biochemical factors, or with other US findings, in patients with acute hepatitis A.

    Full Text Available Introduction The incidence of fractured frontal sinus walls vary from 6% to 12% of all craniofacial injuries. Objective Estimated relation between clinical findings and performed therapeutic procedures in treating fractured frontal sinus walls. To estimate success in performed therapeutic procedures, according to the incidence of postoperative complications and the integrity of injured regions from the functional and esthetical aspect. Method We analyzed, by retrospective clinical investigation, 19 patients with fractured frontal sinus walls and dislocated fragments, treated at the Department for Maxillofacial Surgery, Clinic of Dentistry in Niš, in the period March 1995 - March 2006. The success of therapy was estimated based on the incidence and type of complications and esthetical results in relation to preoperative findings. Results Predominant etiological factor in fractures of frontal sinus walls is trauma sustained in traffic accidents, which occurred in 52.6% of patients in our investigation. In clinical findings, the impression was the predominant sign, present in 16 patients. In 6 cases soft tissue access through already present lacerations or their extensions was employed, in 4 cases it was done by supraciliary access and in 9 by bicoronal access. As a therapeutic measure, drainage was performed in 5 cases, cranialisation in one, ostheoneogenetic access in 11 cases and a simple reposition of fragments in 2 patients with fractured frontal sinus walls. Infection as a complication was absent. All patients were satisfied with postoperative esthetical appearance of the injured region. Conclusion The infection, the lacerations and the direction of fractured lines are dominant factors in the determination of therapeutic procedures used to treat fractured frontal sinus walls. This will result in the low incidence of infection as a postoperative complication and in patient’s satisfaction with postoperative esthetical result of the injured

    Leukemia is a group of malignant diseases involving peripheral blood and bone marrow. Extramedullary tumor manifestation in leukemia can also occur. They more often involve lymph nodes, skin, and bones. Intramuscular leukemic relapse (ILR) is very unusual. The aim of this analysis was to summarize the reported data regarding clinical signs and radiological features of ILR. The PubMed database was searched for publications related to ILR. After an analysis of all identified articles, 20 publications matched the inclusion criteria. The authors of the 20 publications were contacted and provided imaging of their cases for review. The following were recorded: age, gender, primary diagnosis, clinical signs, pattern, localization and size of the intramuscular leukemic relapse. Images of 16 patients were provided [8 computer tomographic (CT) images and 15 magnetic resonance images, MRI]. Furthermore, one patient with ILR was identified in our institutional database. Therefore, images of 17 patients were available for further analysis. Overall, 32 cases with ILR were included in the analysis. In most cases acute myeloid leukemia was diagnosed. Most ILRs were localized in the extremities (44 %) and in the extraocular muscles (44 %). Clinically, ILR manifested as local pain, swelling and muscle weakness. Radiologically, ILR presented most frequently with diffuse muscle infiltration. On postcontrast CT/MRI, most lesions demonstrated homogeneous enhancement. ILRs were hypo-/isointense on T1w and hyperintense on T2w images. ILR manifests commonly as focal pain, swelling and muscle weakness. ILR predominantly involved the extraocular musculature and the extremities. Radiologically, diffuse muscle infiltration was the most common imaging finding. (orig.)

    PURPOSE: The diagnosis of appendicitis is traditionally made on the basis of clinical findings supported by laboratory results. The aim of our study was to determine the accuracy and feasibility of using a relatively new technique of computed tomography (CT) using only colonic contrast medium. MATERIALS AND METHODS: A total of 50 patients clinically diagnosed as having appendicitis were prospectively examined before surgery with thin-collimation helical CT from the L3 level to the acetabular roof with only rectally administered colon contrast medium. The hard copy CT images were reviewed jointly by two radiologists and a consensus was reached for each patient. The results were then compared with the surgical and histological findings at appendicectomy. RESULTS: There were 35 true-positives, one false-positive, 12 true-negatives and two false-negatives for CT. This yielded an accuracy of 94%, sensitivity of 95%, specificity of 92%, positive predictive value of 97% and negative predictive value of 86%. The appendix was identified in 45 patients (90%) and obscured by an inflammatory mass in the remaining five. An alternative diagnosis was found in 10 of 12 normal CT examinations (83%). CONCLUSION: Helical CT with rectal contrast medium is a quick, well tolerated and accurate test to diagnose appendicitis. It can offer alternative, possibly non-surgical diagnosis in patients who would otherwise have undergone laparotomy. Wong, S.K. et al. (2002)

    To analyse the clinical and radiologic findings brain metastasis of breast cancer. Sixty-one of 1399 patients in whom breast cancer was diagnosed between 1983 and 1999 were affected by brain metastasis. Among these 1399, the stage of the breast cancer, in descending order of frequency, was IIA (n=508), I (n=366), IIB (n=247), IIIA (n=189), IIIB (n=45), 0 (n=33) and IV (n=11). The stage of the 61 brain metastases, similarly ordered, was IIB (12.5%), IIA (3.9%), IIIA (3.1%), IIIB (2.2%) and I (0.8%). In all confirmed breast cancers, the age distribution, in descending order of frequency, was 40-49years (n=610), 50-59 (n=301), 30-39 (n=291), 60-69 (n=124), 20-19 (n=41), 70-79 (n=28), and 80-89 (n=4). The age distribution of brain metastasis was 20-29 (14.6%), 30-39 (7.9%), 50-59 (4.6%). 40-49 (2.6%) and 60-69 (1.6%). Imaging findings were available for 35 of the 61 patients affected by brain metastasis, and symptoms from brain among the 35, analysis of the symptoms of this metastasis, the site of the first distant metastasis to an extracranial or cranial organ, the interval from the diagnosis of breast cancer to brain metastasis, the interval from brain metastasis to death, and the difference in survival time between patients with initial and succeeding brain metastasis was undertaken. Brain CT findings were analysed in 29 cases and MRI findings in eight. The most common symptoms were headache and vomiting. Among the 35 brain metastasis patients for whom imaging findings were available, other systemic metastasis occurred in 22. Initial brain metastasis occurred in the remaining 13, and in seven of these there was also coincident organ metastasis, while six showed only brain metastasis, The most frequent intervals from the diagnosis of breast cancer to brain metastasis were 1-2 years(8/35) and 2-3years(8/35). Twenty-six of 35 patients died within one year of brain metastasis. Patients in whom this occurred later survived for longer than those in whom it occurred

    To present the long-term surgical outcome of the bony mastoid and epitympanic obliteration technique with canal wall reconstruction (CWR-BOT) in adults with an unstable cavity after previous canal wall-down surgery for extensive cholesteatoma. Retrospective study. Therapeutic. Tertiary referral center. Fifty consecutive adult patients undergoing a CWR-BOT between 1998 and 2009. (A) Recurrence and residual rates of cholesteatoma, (B) postoperative hygienic status of the ear, including postoperative aspect of the tympanic membrane and external ear canal integrity (EAC), (C) functional outcome, and (D) long-term safety issues. (A) The percentage of ears remaining safe without recurrent or residual disease after CWR-BOT was 96% after a mean follow-up time of 101.8 months. Recurrent cholesteatoma occurred in 2% (n = 1) and a residual cholesteatoma was detected in 2% (n = 1) of the patients. (B) A safe dry, and trouble-free graft and selfcleaning EAC was achieved in 94%. (C) The postoperative hearing results showed a gain of 1.7 dB on pure-tone average air-conduction. (D) Nonecho planar diffusion-weighted imaging (non-EP DW magnetic resonance imaging) documented the residual (n = 1) and recurrent cholesteatoma (n = 1). The 1- and 5-year imaging follow-up revealed no other recurrent or residual disease. The CWR-BOT is a safe and very effective option for treatment of problematic unstable canal wall-down mastoid cavities, resulting in dry trouble-free ears.

    We present the clinical results and ultrasonographic findings of 61 trigger digits treated with percutaneous A1 pulley release. An endoscopic carpal tunnel knife was used for the release in the outpatient department. The mean follow-up period was 3.5 months. A total of 55 digits (90%) had complete relief of their triggering postoperatively. Six digits (10%) had Grade 2 triggering clinically in the early postoperative period.The complications included six cases of insufficient release (10%), scar sensitivity in one patient, short-term hypoaesthesia in three digits (5%), and flexor tendon laceration noted on postoperative ultrasonography in eight digits (13%). No neurovascular damage was noted on the postoperative ultrasonography. Ultrasonograpy provides information about tendon laceration and changes in thickness of the pulleys and confirm A1 pulley release after surgery, but it does not alter clinical decision-making. We believe that pre- and postoperative ultrasonograpy does not need to be included as a routine examination. © The Author(s) 2014.

    Central pontine myelinolysis (CPM) is a neurologic disorder once thought to be uniformly fatal. With the introduction of CT and MRI there was an increasing number of reports on nonfatal cases of CPM. Nearly all reports on nonfata cases describe severe clinical syndromes with tetraparesis, bulbar palsy, and coma. We reviewed nine patients with CPM and compared the size of the pontine lesion on MRI and CT with the severity of clinical presentation. Clinical presentation of CPM was highly variable: The symptoms ranged from severe neurologic disorders to mild neurologic disturbances only. Two of nine patients died from CPM. The size of the pontine lesion did not correlate with the severity of the neurologic illness or the final outcome. Mild forms of CPM might be difficult to diagnose clinically. This applies even more for patients with underlying diseases such as Wernicke's encephalopathy, which in itself might cause a clinical picture similar to that of CPM. Central Pontine Myelinolysis is a major differential diagnosis in acute neurologic deterioration indicating pontine damage. Magnetic resonance imaging is the decisive diagnostic tool for CPM.

    Functional constipation (FC) is a common problem in childhood. In this study, we aimed to analyze the clinical and sociodemographic findings of patients with FC, parenting behaviors, and psychosocial states of children and parents. According to the Roma III diagnosis criteria, 32 patients with FC and 31 healthy controls were included. Patients' clinical and sociodemographic data set associated with constipation was determined. Strengths and Difficulties Questionnaire was used to screen the emotional and behavioral problems in children. To evaluate the parents and family, Beck Depression Inventory, State-Trait Anxiety Inventory, Parental Attitude Research Instrument were used. Emotional and peer problems subscale scores, parental concerns as well as over-parenting attitude were found higher in patients. Significant difference was also observed between the groups in terms of mean score of authoritarian attitude dimensions. Attitude of hostility and rejection and marital discordance was found to be significantly high in patient families. Our study revealed a decrease in the constipation rate with the increasing education level of parents, higher rate of constipation in families with less income than expenses, and lower rate of working mothers in patients with constipation. Parents' depressive symptoms and anxiety level were determined to be considerably higher. A mother's low education level, low socioeconomic level, presence of psychological symptoms, and problems of parental attitude-primarily the authoritarian attitude-increase the risk of FC occurrence. Therefore, FC patients and their families should definitely undergo a psychosocial assessment.

    MRI is frequently utilized to evaluate patients for osteomyelitis. The findings of intramedullary and extramedullary fat globules as well as extramedullary fat-fluid levels can help improve the specificity of MRI for this diagnosis. To correlate these MRI findings with the clinical characteristics in children with osteomyelitis. A retrospective electronic medical record search for pediatric patient charts from March 2004 to November 2009 that contained the word ''osteomyelitis'' in the ''principal diagnosis'' portion of the international classification of disease (ICD) billing code. Each electronic chart was reviewed. MRI examinations of selected children were reviewed by a pediatric radiologist, a general radiologist and a transitional year resident. A total of 10 patients/11 MRI studies were included. Five of the 11 had the MRI finding of extramedullary globular fat signal. There was a significantly increased likelihood of seeing this finding in children of pubertal or postpubertal age compared to those of prepubertal age (p < 0.05). This study provides evidence that the MRI finding of extramedullary fat globules in children with acute osteomyelitis is associated with the clinical characteristic of being within or above the age range for puberty.

    OBJECTIVE: To establish the clinical characteristics, aetiology, neuro-physiological characteristics, imaging findings and other investigations in a cohort of patients with non-traumatic brachial plexopathy (BP). METHODS: A 3-year retrospective study of patients with non-traumatic BP identified by electromyography (EMG) and nerve conduction studies (NCS). Clinical information was retrieved from patients\\' medical charts. RESULTS: Twenty-five patients were identified. Causes of BP included neuralgic amyotrophy (NA) (48%), neoplastic (16%), radiation (8%), post infectious (12%), obstetric (4%), rucksack injury (4%), thoracic outlet syndrome (4%) and iatrogenic (4%). Patients with NA presented acutely in 50%. The onset was subacute in all others. Outcome was better for patients with NA. All patients with neoplastic disease had a previous history of cancer. MRI was abnormal in 3\\/16 patients (18.8%). PET scanning diagnosed metastatic plexopathy in two cases. CONCLUSIONS: NA was the most common cause of BP in our cohort and was associated with a more favourable outcome. The authors note potentially discriminating clinical characteristics in our population that aid in the assessment of patients with brachial plexopathies. We advise NCS and EMG be performed in all patients with suspected plexopathy. Imaging studies are useful in selected patients.

    This review demonstrates the features of truly suprasellar masses in modern imaging based on the clinical, CT, and MRI findings of 42 patients with suprasellar masses in correlation to the histologic findings. The radiologic examinations were evaluated retrospectively to determine if diagnosis can be made based on specific imaging patterns. The most frequent clinical findings of space-occupying suprasellar masses were visual disturbances, diabetes insipidus, and symptoms and signs of occlusive hydrocephalus. There were no clinical features specific for any of the observed masses. Craniopharyngiomas were the most frequent tumors. They appeared in two different forms, as cystic and as solid enhancing masses. The cystic tumors could not be differentiated from cystic hamartomas or cystic gliomas by CT or MRI. The solid craniopharyngiomas were similar to meningiomas and hamartomas. In craniopharyngiomas of adults calcifications were not common. In CT and especially in MRI gliomas were characterized by the diffuse infiltration of the adjacent brain tissue or optic nerve. Except for meningiomas, all lesions were highly variable in appearance, making a reliable characterization by CT and MRI difficult in many cases. However, administration of contrast media in some cases resulted in a better tumor delineation. Compared with unenhanced MRI the enhanced scans did not increase diagnostic efficacy for neoplasms, but were helpful in the differentiation from inflammatory diseases. The MRI technique was superior to CT in demonstrating the anatomic relationships, thus facilitating evaluation of origin and extent of the lesions. The CT technique, of course, was more reliable in the detection of calcifications. Both CT and MRI are not tissue-specific, however, and suprasellar tumors as well as many other neoplasms cannot be classified using only one of these imaging techniques. (orig.)

    The objective of this study was to determine the clinical and laboratory characteristics, psychiatric manifestations and magnetic resonance imaging (MRI) findings in children and adolescents with Sydenham chorea (SyC). The imaging examination was repeated 1 year after the acute phase of SyC. There were 19 patients with a mean age of 11.7 years and a predominance of females (79%);68% had generalized chorea and 53% moderate chorea. SyC presented as an isolated manifestation in 74%. No association between SyC and obsessive-compulsive disorder was found. Mental health problems were present in 45% of the patients. MRI analysis revealed persistent alterations in the caudate nucleus in three patients (16%), who presented recurrent episodes of chorea during the study. In one patient, MRI revealed the presence of nodular heteropathy close to the caudate nucleus region. We conclude that attention problems can be associated with acute clinical features of SyC and persistent alterations in the basal nuclei, evidenced by MRI, can be found in some patients who tend to suffer prolonged attacks and a greater number of recurrences.

    The increasing use of magnetic resonance imaging (MRI) in clinical diagnostics means that patients and physicians are confronted more often with incidental findings. In the literature there are fluctuating data on the incidence of such findings and guidelines concerning the further procedure exist in only very few cases, such as incidental aneurysms and pituitary adenomas. The diagnostic and therapeutic implications which can be derived from incidental findings depend on multiple factors, such as anatomical location, patient age, comorbidity and patient wishes. For this reason it often makes sense to refer patients with incidental findings to an interdisciplinary neurological center at an early stage. In this review frequent incidental cerebral findings, epidemiological data, imaging criteria and, where possible, recommendations for the further procedure are shown. (orig.) [German] Durch den gehaeuften Einsatz der MRT in der zerebralen Diagnostik werden Arzt und Patienten in zunehmendem Masse mit Zufallsbefunden, auch Nebenbefunde genannt, konfrontiert. In der Literatur existieren sehr schwankende Angaben zur Haeufigkeit solcher Zufallsbefunde. Nur fuer einzelne dieser Befunde, wie z. B. das inzidentelle Aneurysma oder das Hypophysenadenom, existieren Leitlinien fuer das weitere Prozedere. Die aus einem Zufallsbefund abzuleitenden diagnostischen und therapeutischen Konsequenzen sind von vielen Faktoren, wie z. B. der anatomischen Lage, dem Patientenalter, den Komorbiditaeten und dem Patientenwunsch abhaengig. Daher ist es oft sinnvoll, den Patienten mit einem Zufallsbefund fruehzeitig in einem interdisziplinaeren Neurozentrum vorzustellen. In der vorliegenden Arbeit werden haeufige zerebrale Zufallsbefunde mit epidemiologischen Daten, bildgebenden Kriterien und - wenn moeglich - Empfehlungen bzgl. des weiteren Vorgehens gezeigt.

    The use of a controlled vocabulary set in a hospital-wide clinical information system is of crucial importance for many departmental database systems to communicate and exchange information. In the absence of an internationally recognized clinical controlled vocabulary set, a new extension of the International statistical Classification of Diseases (ICD) is proposed. It expands the scope of the standard ICD beyond diagnosis and procedures to clinical terminology. In addition, the common Clinical Findings Dictionary (CFD) further records the definition of clinical entities. The construction of the vocabulary set and the CFD is incremental and manual. Tools have been implemented to facilitate the tasks of defining/maintaining/publishing dictionary versions. The design of database applications in the integrated clinical information system is driven by the CFD which is part of the Medical Questionnaire Designer tool. Several integrated clinical database applications in the field of diabetes and neuro-surgery have been developed at the HUG.

    To determine the clinical pattern of presentation and biochemical characteristics of glycogen storage disease (GSD) type 1a in children at a tertiary referral centre. Study Design: Descriptive/ cross sectional study. Place and Duration of Study: Department of Pediatric, division of Gastroenterology and Hepatology of the Children's hospital, Lahore over a period of 11 years. Patients and Methods: Confirmed cases of glycogen storage disease (clinical plus biochemical findings consistent with GSD 1a and proven on liver biopsy) were enrolled in this study from neonatal age till 18 years. Data was retrieved from files and electronic record for these cases. Diagnosis was made on the basis of history, clinical findings including hepatomegaly, hypertriglyceridemia, hypercholesterolemia, hypoglycemia and hyperuricemia (if present). Diagnosis was confirmed on liver biopsy. Patients with other storage disorders and benign and malignant tumours were excluded from the study. Results: Total patients included in the study were 360 with male to female ratio of 1.25:1. Median age at the time of diagnosis was 25.6 months (age range from one month to 18 years). Most common presentation was abdominal distension (83%) followed by failure to thrive (69%) and recurrent wheezing and diarrhoea (44%) each. Seizures were present in only 1/3rd of children. Other presentations included vomiting, respiratory distress, altered sensorium, nephrocalcinosis, epistaxis and hypothyroidism. Few patients around 11% presented with acute hepatitis and later were diagnosed as GSD. Significant hepatomegaly was evident in almost all patients but nephromegaly was present in only 5.5% patients. All children had marked hypertriglyceridemia but cholesterol levels were raised in 1/3rd of children. A large majority of children had deranged ALT more than 2 times of normal and around 38% children had marked anemia. Significant hypoglycemia and metabolic acidosis was documented in around 1/3rd of children

    In 2007, The National Board of Osteopathic Medical Examiners (NBOME) instituted a policy to address the accuracy and integrity of postencounter written documentation recorded during the Comprehensive Osteopathic Medical Licensing Examination Level 2-Performance Evaluation (COMLEX-USA Level 2-PE). This policy was instituted not only to protect the integrity of the examination, but also to highlight that overdocumentation of clinical findings not obtained during patient encounters may jeopardize patient safety. To investigate overall and domain pass/fail patterns of candidates who misrepresented clinical findings with regard to past and subsequent performance on COMLEX-USA Level 2-PE. Specifically, to investigate what percentage of candidates failed because of misrepresentation on first attempts and how they performed on subsequent administrations, as well as the previous performance patterns of candidates who failed because of misrepresentation on examination retakes. Historical records from NBOME's COMLEX-USA Level 2-PE database (testing cycles 2007-2008, 2008-2009, and 2009-2010) were used to analyze overall and domain pass/fail patterns of candidates who failed at least once because of misrepresentation of clinical findings. Of the 24 candidates who failed because of misrepresentation of postencounter (SOAP) notes, 20 candidates (83%) were first-time examinees. Four candidates (17%) were repeating the examination, 2 of whom were making a third attempt to pass. Among these 20 candidates who failed because of misrepresentation of clinical findings on their first attempt, 19 passed on their next attempt. At the time of study analysis, all but 2 candidates eventually passed the examination in subsequent attempts. Among candidates found to have misrepresented clinical findings on postencounter written documentation on COMLEX-USA Level 2-PE, no pattern existed between their past or subsequent performance with regard to overall or domain pass/fail results.

    Purpose: The overall objective was to review clinical data and CT findings of pulmonary infection caused by different pathogens after kidney transplantation in an attempt to help early clinical qualitative diagnosis. Materials and methods: 446 cases of clinically confirmed pulmonary infection after kidney transplantation in recent 10 years were evaluated with respect to the time of occurrence and 89 cases with complete CT data and pathogenic diagnosis were further analyzed for pathogen types and CT manifestations. Statistical analysis was performed using Fisher's exact test. Results: Pulmonary infection reached the peak in 3 months after transplantation. Bacterial infection and mixed infection were predominant between 1 and 6 months. And most tuberculosis occurred after one year. Bacterial (38.2%) and mixed infections (38.2%) were the common types. The next was fungal infection, tuberculosis and viral infection (10.1%, 7.9% and 5.6%, respectively). CT manifestations of pulmonary infections after kidney transplantation were diverse and complex, lacking characteristic signs. Conclusion: More than 3/4 of pulmonary infections after kidney transplantation can be attributed to bacteria and mixed pathogens. The combination of time course, clinical data and CT manifestations plays an important role in the early clinical qualitative diagnosis.

    Dogs with advanced heart failure are a clinical challenge for veterinarians but there are no studies reporting clinical features and outcome of this population. To describe clinical findings and outcome of dogs with advanced heart failure caused by degenerative mitral valve disease (DMVD). Fifty-four dogs with advanced heart failure because of DMVD. For study purposes, advanced heart failure was defined as recurrence of congestive heart failure signs despite receiving the initially prescribed dose of pimobendan, angiotensin-converting-enzyme inhibitor (ACEI), and furosemide >4 mg/kg/day. Data were collected for the time of diagnosis of Stage C heart failure and time of diagnosis of advanced heart failure. Date of death was recorded. At the diagnosis of advanced heart failure, doses of pimobendan (n = 30), furosemide (n = 28), ACEI (n = 13), and spironolactone (n = 4) were increased, with ≥1 new medications added in most dogs. After initial diagnosis of advanced heart failure, 38 (70%) dogs had additional medications adjustments (median = 2 [range, 0-27]), with the final total medication number ranging from 2-10 (median = 5). Median survival time after diagnosis of advanced heart failure was 281 days (range, 3-885 days). Dogs receiving a furosemide dose >6.70 mg/kg/day had significantly longer median survival times (402 days [range, 3-885 days] versus 129 days [range 9-853 days]; P = .017). Dogs with advanced heart failure can have relatively long survival times. Higher furosemide dose and non-hospitalization were associated with longer survival. Copyright © 2018 The Authors.

    Physicians need easy access to evidence for clinical decisions while they care for patients but, to our knowledge, no investigators have assessed use of evidence during rounds with house staff. To determine if it was feasible to find and apply evidence during clinical rounds, using an "evidence cart" that contains multiple sources of evidence and the means for projecting and printing them. Descriptive feasibility study of use of evidence during 1 month (April 1997) and anonymous questionnaire (May 1997). General medicine inpatient service. Medical students, house staff, fellows, and attending consultant. Evidence cart that included 2 secondary sources developed by the department (critically appraised topics [CATs] and Redbook), Best Evidence, JAMA Rational Clinical Examination series, the Cochrane Library, MEDLINE, a physical examination textbook, a radiology anatomy textbook, and a Simulscope, which allows several people to listen simultaneously to the same signs on physical examination. Number of times sources were used, type of sources searched and success of searches, time needed to search, and whether the search affected patient care. The evidence cart was used 98 times, but could not be taken on bedside rounds because of its bulk; hard copies of several sources were taken instead. When the evidence cart was used during team rounds and student rounds, some sources could be accessed quickly enough (10.2-25.4 seconds) to be practical on our service. Of 98 searches, 79 (81%) sought evidence that could affect diagnostic and/or treatment decisions. Seventy-one (90%) of 79 searches regarding patient management were successful, and when assessed from the perspective of the most junior team members responsible for each patient's evaluation and management, 37 (52%) of the 71 successful searches confirmed their current or tentative diagnostic or treatment plans, 18 (25%) led to a new diagnostic skill, an additional test, or a new management decision, and 16 (23

    To determine frequency, imaging features and clinical significance of herniations of brain parenchyma into dural venous sinuses (DVS) and/or calvarium found on MRI. A total of 6160 brain MRI examinations containing at least one high-resolution T1- or T2-weighted sequence were retrospectively evaluated to determine the presence of incidental brain herniations into the DVS or calvarium. MRI sequences available for review were evaluated according to their capability to demonstrate these herniations. Patients' symptoms and clinical findings were recorded. Twenty-one (0.32 %) brain parenchyma herniations into the DVS (n = 18) or calvarium (n = 3) in 20 patients were detected. The most common locations of the herniations were the transverse sinuses (n = 13) and those involving inferior gyrus of the temporal lobe (n = 9). High-resolution T1- and T2-weighted sequences were equally useful in the detection of these brain herniations. According to clinical symptoms, brain herniations were considered to be incidental but headaches were present in nine patients. Brain herniations with surrounding cerebrospinal fluid (CSF) into the DVS and/or calvarium are incidental findings and not proven to be associated with any symptoms. Although rare, these herniations are more common than previously recognized and should not be confused with arachnoid granulations, clots or tumours. (orig.)

    The clinical courses and a follow-up study on the MRI findings in four cases with early infantile epileptic encephalopathy (EIEE) are reported. The patients consisted of one male and three females. The age at onset was before 15 days on life and the etiology was unknown in all cases. EEG improvement and a decrease in seizure frequency were seen after treatment with ACTH and anticonvulsants in three of the four patients, while no treatment was effective in the other patient who developed Lennox-Gastaut syndrome through West syndrome. Psychomotor development of all patients was severely retarded, and it was impossible for three cases to gain head control until 12 months old. MRI findings revealed dysmyelination of white matter in the cerebrum in three patients and asymmetrical myelination in the other patient. These results suggested that EIEE is based on brain immaturity combined with dysmyelination.

    Computed tomography is currently the method of choice for the diagnostic and staging of lymphomas. Computed tomography enables accurate measurements of both tumor extent and volume and provides information that can be used to plan an appropriate strategy for the treatment. The purpose of the present article is to describe and analyze the chest and abdomen computed tomography and ultrasound findings in HIV-negative patients with lymphoma. Clinical abnormalities, such as the reason the patient sought medical assistance already showing evidence of lymphocytic disease (not yet diagnosed at this point) and the physical examination abnormalities seen on the first consultation were also studied. This study comprised 30 patients: 40% with non-Hodgkin lymphoma, 46,6% with Hodgkin lymphoma, 10% with Burkitt's lymphoma and 3,3% with lymphoblastic lymphoma. (author)

    We aimed to analyze preoperative and intraoperative clinical characteristics of chronic perforated otitis media by patient age. We analyzed 137 tympanoplasties for chronic perforated otitis media in 133 patients. Exclusion criteria were ear adhesions, cholesteatoma, and a history of tympanoplasty. Patients were divided into a younger group (aged 15-39 years), a middle group (40-64 years), and an elderly group (≥65 years). We compared tympanoplasty technique (using Wullstein classification), mastoid air-cell area measured by temporal bone computed tomography, preoperative aeration of the temporal bone, mean preoperative hearing (at 500 Hz, 1000 Hz, and 2000 Hz), and patch effect calculated by the pre- and post-patch air-bone gap at frequencies of 250 Hz and 500 Hz among the three age groups. Although type I tympanoplasty was performed most frequently in all age groups, it was performed significantly less often in the elderly group (pgroup (page groups (pgroups. The mean patch effect was significantly better in the younger group than in middle or elderly groups (p<0.05). The less pneumatized mastoid and ossicular diseases in elderly patients with chronic perforated otitis media suggest that they had longer lasting and more severe childhood middle ear pathologies than did younger patients.

    Background: Despite reduction in ld mortality during last decade, lower respiratory tract infection (LRTI) remained number one killer of under-five. The current study aimed to assess the association of haematological and radiological findings with clinical outcome in hospitalized children 2-36 months old with severe LRTI. Methods: In the current cross sectional study, 581 children 2-36 months old with severe LRTI were enrolled and followed at the Children Hospital, Islamabad, between 2011 and 2014. At the time of enrolment, complete history of present illness, anthropometric measurements, blood sample and chest radiograph were obtained. The primary outcome was either early clinical response (within 72 hours) or delayed clinical response (>72 hours). Multivariable logistic regression was performed to examine the association between haematological and radiological findings with clinical outcome, adjusted for potential confounding factors. Results: Of 581 enrolled children, 292 (50.3 percent) children had early, and 289 (49.7 percent) had delayed clinical response. The multivariable logistic regression showed that leucocytosis (OR 1.79, 95 percent CI 1.15-2.79), neutrophilia (OR 1.91, 95 percent CI 1.29-2.84), radiological interstitial pneumonia (OR 2.49, 95 percent CI 1.70-3.64), and lobar consolidation (OR 6.00, 95 percent CI 2.41-14.96) were significantly associated with delayed clinical response, after adjusted for potential confounding factors. Conclusions: Delayed clinical response was significantly associated with abnormal haematological and radiological findings at the time of admission in children 2-36 months old with severe LRTI. Haematological and radiological findings at the time of presentation are useful for predicting delayed clinical response in children 2-36 months old with severe LRTI. (author)

    The function of the Eustachian tube plays a significant role in increased risk chronic suppurative otitis media (CSOM). The angle of the Eustachian tube is a predisposing factor for Eustachian tube dysfunction and clearance disorder of the middle ear. The aim of this study was to compare the mean angle of a Eustachian tube of CSOM ears and normal ears. This research was a cross-sectional study consisting of 19 patients of CSOM without cholesteatoma, 19 patients of CSOM with cholesteatoma and 19 patients with normal ears. All patients were examined using CT Temporal, and the angle of the eustachian tube was measured using multiplanar reconstruction technique. The mean angle of Eustachian tube in CSOM patients without cholesteatoma was 32.82° (SD=3.82), in CSOM with cholesteatoma was 27.74° (SD=4.44) and in normal ears was 33.61° (SD=3.83). Based on Kruskal-Wallis test, there was a significant difference in the angle of a Eustachian tube of these three groups (p<0.001). There was a significant difference between the mean angle of the Eustachian tube in CSOM ears and normal ears.

    Anthrax, caused by the bacterium Bacillus anthracis, is one of the oldest documented infectious diseases in both livestock and humans. We aimed to evaluate clinical findings and risk factors of patients with cutaneous anthrax infection and report anti-lethal factor (LF) IgG and anti-protective antigen (PA) IgG titers in the serologic diagnosis of disease. In this study, serum samples of 18 cutaneous anthrax patients were collected and anti-LF IgG and anti-PA IgG titers were measured by enzyme-linked immunosorbent assay (ELISA). Twelve (67%) males and 6 (33%) females, with a mean age of 36.06 ± 16.58 years were included in the study. Risk factors identified in the patient population studied were slaughtering (28%), flaying (56%), chopping meat (67%), burying diseased animal corpses (17%) and milking (6%) livestock. Black eschar formation (94%), pruritus (78%) and painful lymphadenopathy (61%) were first three common clinical signs and symptoms, respectively. Fourteen (78%) patients produced a positive IgG response against PA, 11 (61%) patients produced against LF. Three (17%) patients had no response to either antigen. A detailed history of contact with sick animals or animal products along with clinical findings should be taken at the first step for the diagnosis of cutaneous anthrax infection. Serologic detection of anti-LF IgG and anti-PA IgG with ELISA may be useful auxillary method for establishing the diagnosis.

    Cholecystectomy is the current standard recommended treatment for dogs with gallbladder mucoceles. However, medical management with monitoring has also been recommended for asymptomatic dogs. The purpose of this retrospective study was to compare ultrasonographic patterns of gallbladder mucoceles with clinical disease status in a group of dogs. For each included dog, the ultrasonographic pattern of the mucocele was classified into one of six types: type 1, immobile echogenic bile; type 2, incomplete stellate pattern; type 3, typical stellate pattern; type 4, kiwi like pattern and stellate combination; type 5, kiwi like pattern with residual central echogenic bile; and type 6, kiwi like pattern. A total of 43 dogs were included. Twenty-four dogs, including 11 dogs with gallbladder rupture, were symptomatic. Nineteen dogs were asymptomatic. Cholecystectomy (n = 19), medical therapy (n = 17), or monitoring (n = 6) treatments were applied according to clinical signs and owners' requests. One dog suspected of having gallbladder rupture was euthanized. Frequencies of gallbladder mucocele patterns were as follows: type 1 = 10 (23%), type 2 = 13 (30%), type 3 = 5 (12%), type 4 = 11 (26%), type 5 = 4 (9%), and type 6 = 0. In dogs with gallbladder rupture, type 2 (8/13) was the most common. No significant correlations were found between ultrasonographic patterns of gallbladder mucoceles and clinical disease status or gallbladder rupture. Findings indicated that ultrasonographic patterns of gallbladder mucoceles may not be valid bases for treatment recommendations in dogs. © 2013 American College of Veterinary Radiology.

    Full Text Available Background. Mycobacterium tuberculosis (M.TB causes a wide spectrum of clinical diseases. The prevalence of TB is different in various parts of Iran and throughout the world. The present study aimed to determine the clinical epidemiology and paraclinical findings of TB. Methods. A cross-sectional study was conducted from 2008 to 2013. Patient demographic, clinical, and radiologic characteristics, picked up from the TB patient’s files, were collected using a standard questionnaire format. Data was entered and analyzed using the SPSS version 16 statistical software and P value < 0.05 was considered statistically significant. Results. Out of 212 patients enrolled in this study 62% were male and the mean age was about 50 years old. 98.6% were Iranian, and 46.2% were rural. Prevalence of smear-positive TB was 66.4%. Prevalence of positive PPD was 50.7% with no significant difference between HIV-positive and -negative patients (P = 0.8. Prevalence of diabetes mellitus was 17%. 36% of the patients had history of smoking and about 29.3% were addicted to narcotics. Cough was the most common symptom (94.5% and 84% had sputum. 15 cases (7% had extrapulmonary TB. The mean time between the onset of symptoms and admission was 46.5 days. The delay for admission between urban and rural populations was not significantly different (P = 0.68; but for those who were in prison, the delay was significant (P = 0.02. About 46% of the patients had cavitary lesions in CXRs. Conclusion. Timely diagnosis of TB especially in prisoners by understanding its most important epidemiologic characteristics and clinical features can help to make an early treatment and prevent spread of mycobacteria and their complications.

    Objective: To assess the relationship between left anterior descending (LAD) coronary artery myocardial bridging detected by 64-slice computed tomography (CT) and clinical findings. Methods: 221 consecutive patients were examined with coronary 64-slice CT angiography. 21 patients with coronary stenosis >50% were excluded. The length, depth, and luminal narrowing of LAD myocardial bridges during systole and diastole were measured. CT findings were compared with the treadmill ECG-stress test, and clinical symptoms. Results: Myocardial bridges of the LAD were found in 23% of patients (51/221) (length, 14.9 ± 6.5 mm; depth, 2.6 ± 1.6 mm). A significant difference was noted between the LAD luminal diameter before the intramyocardial course and intramyocardially, for both diastole and systole (p 50% was found in 3/25 (8%). 30/51 (59%) of bridges were 'deep' (>2 mm myocardial depth), 21/51 (41%) were 'superficial'. The prevalence of a positive ECG-stress tests for the anterior myocardial region was significantly higher in patients with LAD myocardial bridges (34/50; 68%) compared to those without (28/144; 19.4%) (p < 0.001). There was no difference between 'superficial' and 'deep' LAD myocardial bridges in regard to a positive treadmill ECG-stress test. Typical angina was rare with 6%. Conclusion: LAD myocardial bridges are common findings and can possibly explain a positive exercise ECG-stress test for anterior myocardial ischemia. Intramyocardial LAD segments show mild-to-moderate luminal narrowing at rest, which is higher during end-systolic phase.

    Full Text Available BACKGROUND: Buruli ulcer (BU is a skin disease caused by Mycobacterium ulcerans, with endemicity predominantly in sub-Saharan Africa and south-eastern Australia. The mode of transmission and the environmental reservoir(s of the bacterium and remain elusive. Real-time PCR investigations have detected M. ulcerans DNA in a variety of Australian environmental samples, including the faeces of native possums with and without clinical evidence of infection. This report seeks to expand on previously published findings by the authors' investigative group with regards to clinical and subclinical disease in selected wild possum species in BU-endemic areas of Victoria, Australia. METHODOLOGY/PRINCIPAL FINDINGS: Twenty-seven clinical cases of M. ulcerans infection in free-ranging possums from southeastern Australia were identified retrospectively and prospectively between 1998-2011. Common ringtail possums (Pseudocheirus peregrinus, a common brushtail possum (Trichosurus vulpecula and a mountain brushtail possum (Trichosurus cunninghami were included in the clinically affected cohort. Most clinically apparent cases were adults with solitary or multiple ulcerative cutaneous lesions, generally confined to the face, limbs and/or tail. The disease was minor and self-limiting in the case of both Trichosurus spp. possums. In contrast, many of the common ringtail possums had cutaneous disease involving disparate anatomical sites, and in four cases there was evidence of systemic disease at post mortem examination. Where tested using real-time PCR targeted at IS2404, animals typically had significant levels of M. ulcerans DNA throughout the gut and/or faeces. A further 12 possums without cutaneous lesions were found to have PCR-positive gut contents and/or faeces (subclinical cases, and in one of these the organism was cultured from liver tissue. Comparisons were made between clinically and subclinically affected possums, and 61 PCR-negative, non-affected individuals

    Full Text Available Introduction: To study the long-term complications of tympanostomy tube insertion in young children 10 years after surgery.   Materials and Methods: In September 2011, the medical records of all patients who had undergone myringotomy with tympanostomy tube insertion between February 2000 and March 2001 at the two general hospitals of Isfahan University of Medical Sciences were studied. Of the 98 patients who fulfilled the inclusion criteria, 82 patients agreed to participate and were enrolled in the study. The complications of the operation were evaluated in these patients.   Results: Of the 164 ears that were operated on, myringosclerosis was found in 17.1%, atrophy of the tympanic membrane in 1.2%, permanent perforation of the tympanic membrane in 0.6% and tympanic membrane atelectasis in 0.6%. None of the patients developed cholesteatoma as a complication of tympanostomy tube insertion.   Conclusion:  Considering the low risk of serious complications after 10 years, tympanostomy tube insertion is a safe and effective treatment option in the treatment of otitis media with effusion.

    The diagnosis of allergic bronchopulmonary mycosis (ABPM) has traditionally relied widely on Rosenberg's criteria, which emphasize immunologic responses while overlooking the investigation of mucous plugs as a primary criterion. Therefore, the characteristics of biopsy-proven ABPM require further elucidation. The aim of this study was to analyze the clinical characteristics of biopsy-proven ABPM and address whether full compliance with clinical criteria, such as the presence of asthma, and certain laboratory findings is necessary to establish a diagnosis of ABPM. We retrospectively analyzed 17 patients with biopsy-proven ABPM focusing on causative fungi and laboratory findings. Causative fungi included Aspergillus sp. in seven patients, Schizophyllum commune in four patients, Penicillium sp. in two patients and unknown in five patients. Bronchial asthma was observed in 10 patients, eosinophilia was observed in 10 patients and an increased serum immunoglobulin (Ig) E level was observed in 14 of the 17 patients. IgG for Aspergillus sp. was positive in six of the seven patients with ABPM due to Aspergillus and turned positive in the remaining patient during follow-up. Technological limitations prevented the measurement of specific IgE for S. commune and IgG for S. commune and Penicillium sp. in most patients. Computed tomography revealed central bronchiectasis, pulmonary infiltration and mucous plugs in all patients. Causative fungi other than Aspergillus sp. are not uncommon, and immunological tests for other fungi should be popularized. Asthma and characteristic laboratory findings, such as peripheral blood eosinophilia, increased serum IgE and precipitating antibodies, may not always be required to diagnose ABPM. The importance of typical pathologic findings of mucous plugs for diagnosing ABPM requires reevaluation. Further studies are needed to establish more elaborate diagnostic criteria for ABPM.

    To find out the impairment of hearing associated with radical mastoidectomy by measuring the quantitative difference in the functional hearing level before and after radical mastoidectomy operation without tympanoplasty. Cross-sectional comparative study. Department of Otorhinolaryngology and Head Neck Surgery, Bahawal Victoria Hospital, Bahawalpur and PNS Shifa Hospital, Karachi, from November 2009 to January 2013. Eighty-five patients, diagnosed clinically as chronic suppurative otitis media with extensive cholesteatoma having history of ear discharge and hearing impairment for more than 6 weeks duration and requiring radical mastoidectomy for treatment, were included in this study. Pure tone audiogram was done before and after radical mastoidectomy. Hearing impairment was compared in each patient before and after the operation. Among the 85 patients, 54 (63.5%) were males and 31 (36.5%) were females, with the age ranged between 18 to 63 years, mean age being 42.31 4.8 years. The mean increase in hearing loss after radical mastoidectomy in air conduction was 7.19 dB, bone conduction was 4.16 dB, and air-bone gap was 3.75 dB (0.001). The ear became dry and safe in 82 patients (96.5%) out of a total of 85, and only 3 patients required revision surgery at a second stage. Radical mastoidectomy has a least negligible effect on hearing status and one should not limit this technique due to the concern of aggravated hearing in patients with extensive cholesteatoma at the cost of dry and safe ears, which should be of prime importance.

    To evaluate the correlation of clinical, laboratory, and pathological features at presentation of focal segmental sclerosis (FSGS), we reviewed in a cross sectional study the pathological findings of kidney biopsies in 64 cases of primary FSGS, and correlated them with the clinical and laboratory data obtained at the time of the biopsies. The data included blood pressure, glomerular filtration rate (GFR), serum albumin, and the level of proteinuria. The mean level of serum creatinine was significantly higher in the biopsies' findings of synechiae (adhesions) in the Bowman's capsule, interstitial fibrosis, and global scars (P< 0.05), and mean level of GFR was significantly lower with the presence of interstitial fibrosis (P< 0.05). Furthermore, there was a positive correlation between the level of serum creatinine and global sclerosis (r= 2.21, P= 0.04), and a negative correlation between the level of GFR and global sclerosis(r= 2.01, P= 0.02). All the patients with renal insufficiency had interstitial fibrosis in their biopsies in comparison of only the 24 patients (48%) of the group without renal insufficiency (P< 0.05). There was no significant difference between patients with and without hypertension and nephritic-ranged proteinuria. We conclude that we found a correlation of renal insufficiency in primary FSGS patients with interstitial fibrosis, global scars and the synechiae of Bowman's capsule in their biopsies. (author)

  19. Right brain, left brain in depressive disorders: Clinical and theoretical implications of behavioral, electrophysiological and neuroimaging findings.

    The right and left side of the brain are asymmetric in anatomy and function. We review electrophysiological (EEG and event-related potential), behavioral (dichotic and visual perceptual asymmetry), and neuroimaging (PET, MRI, NIRS) evidence of right-left asymmetry in depressive disorders. Recent electrophysiological and fMRI studies of emotional processing have provided new evidence of altered laterality in depressive disorders. EEG alpha asymmetry and neuroimaging findings at rest and during cognitive or emotional tasks are consistent with reduced left prefrontal activity in depressed patients, which may impair downregulation of amygdala response to negative emotional information. Dichotic listening and visual hemifield findings for non-verbal or emotional processing have revealed abnormal perceptual asymmetry in depressive disorders, and electrophysiological findings have shown reduced right-lateralized responsivity to emotional stimuli in occipitotemporal or parietotemporal cortex. We discuss models of neural networks underlying these alterations. Of clinical relevance, individual differences among depressed patients on measures of right-left brain function are related to diagnostic subtype of depression, comorbidity with anxiety disorders, and clinical response to antidepressants or cognitive behavioral therapy.

    Full Text Available Objective: To analyse the various abnormal transabdominal ultrasound findings in patients with clinical suspicion of chronic liver disease in our environment with a view of comparing our findings with other existing literatures. Methods: A total of 61 consecutive patients with clinical signs and symptoms of chronic liver disease attending medical outpatient clinic at the Department of Medicine, Usmanu Danfodiyo University, Teaching Hospital Sokoto and Federal Medical Centre Birnin Kebbi were scanned at Radiology Departments for any abnormal intraabdominal findings from May 2011 to April 2012. All the patients were scanned with Apogee 800 plus (Japan 2002 and Concept D (Dynamic Imaging Scotland Ultrasound scanners with a variable frequency probes at 5-12 MHz. Results: A total of 61 abdominal ultrasounds were performed during this study period. All the cases met the inclusion criteria. The mean age was (46.0依12.6 years (ranged 50 years. The mean liver size was (13.25依1.48 cm (ranged 11 cm and (14.00依0.77 cm (ranged 0.77 cm for right and left lobe respectively. The mean spleen size was (15.90依1.22 cm (ranged 6 cm. The sex distribution was males 43 (70.49% and females 18 (29.5%. Of the 61 cases included, the indication for the abdominal ultrasonography were hepatitis 1 (1.6%, liver cirrhosis 20 (50.82%, obstructive jaundice 2 (3.28%, chronic liver disease 25 (40.98% and chronic abdominal swelling 2 (3.2%. Conclusions: In conclusion, our study has demonstrated various abnormal transabdominal ultrasound findings in patients suspected with chronic liver disease in our locality. Ultrasound is useful in the diagnosis of chronic liver disease in daily clinical practice. However, the sensitivity can be improved if a high frequency probe is used and done by experienced and dedicated operators. Liver biopsy remains the gold standard especially when patients are clinically asymptomatic.

    Germline genomic testing is increasingly used in research to identify genetic causes of disease, including cancer. However, there is evidence that individuals who are notified of clinically actionable research findings have difficulty making informed decisions regarding uptake of genetic counseling for these findings. This study aimed to produce and pilot test a decision aid to assist participants in genomic research studies who are notified of clinically actionable research findings to make informed choices regarding uptake of genetic counseling. Development was guided by published literature, the International Patient Decision Aid Standards, and the expertise of a steering committee of clinicians, researchers, and consumers. Decision aid acceptability was assessed by self-report questionnaire. All 19 participants stated that the decision aid was easy to read, clearly presented, increased their understanding of the implications of taking up research findings, and would be helpful in decision-making. While low to moderate levels of distress/worry were reported after reading the booklet, a majority of participants also reported feeling reassured. All participants would recommend the booklet to others considering uptake of clinically actionable research findings. Results indicate the decision aid is acceptable to the target audience, with potential as a useful decision support tool for genomic research participants.

    The purpose of this study is to evaluate the clinical and radiographic findings of localized foreign body (FB) granulomas on mammograms. This study involved 13 patients with localized FB granulomas on mammograms; their history of mammoplasty or other plastic procedures was obtained by telephone interviews. Two radiologists analyzed the location and morphology of FB granulomas and the presence of associated linear densities or parenchymal distortion on mammograms. Four patients underwent ultrasonography. No patient had a history of mammoplasty. All 13, however, had a history of plastic procedure, three to 22 (average, 12) years previously, as follows: foreign materials including silicone liquid and oil such as paraffin had been injected into the anterior neck area of nine patients, the representing FB granulomas were distributed bilaterally in nine patients; they were noted in the suggesting fibrosis. There was no calcification or parenchymal distortion. Though in three cases, the masses were palpable. Ultrasonography revealed several anechoic nodules with posterior enhancement in subcutaneous fatty layers, and in one, 0.2 cc of oil droplet had been aspirated under ultrasonographic guidance. Localized FB granulomas of the breast could be caused by the migration of FB from cervicofacial areas. Mammography showed characteristic distribution of upper inner portions, and the findings were similiar to those of mild interstitial mammoplasty. (author). 13 refs., 2 figs

    A retrospective analysis of the CT and MR findings of 14 pediatric patients with brain stem tumors was performed to evaluate whether the clinical outcome could be predicted from a radiographic pattern of the tumors. CT was performed in 11 patients and MR was performed in 14 patients. Ten patients were treated with radiation therapy (RT) alone, 2 patients with RT and chemotherapy, and 2 patients underwent subtotal resection. After treatment, 9 patients died within 10 months, and 5 patients were alive for 9 months to 51 months. There was no statistically significant correlation between survival and tumor location or size, but in 2 cases of exophytic growing tumor, a subtotal resection of the tumor was possible and the patients were alive for 9 months and 24 months, respectively. The tumors with a cystic portion and definite rim enhancement revealed a poor response to conventional RT, and all 6 patients died within 10 months. In conclusion, a better prognosis is predicted in the case of an exophytic growing tumor after surgical resection, but the definite ring-enhancing tumor showed a poor response on conventional RT. Also, we should consider a more active therapeutic approach such as hyperfractionated RT or combinations of chemotherapy to improve the prognosis

    Objective: to describe and compare imaging methods and clinical findings of cerebral venous thrombosis in four full-term neonates without brain damage, admitted to a neonatal intensive care unit. Materials and methods: ten-year review of four cases diagnosed with cerebral venous thrombosis by transfontanellar ultrasonography associated with Doppler fluxometry and confirmed by magnetic resonance imaging/magnetic resonance angiography in correlation with clinical findings and neurological progression. Results: ultrasonography presented normal results in 75% of cases and magnetic resonance imaging in 100%. Doppler fluxometry and magnetic resonance angiography were abnormal in 100% of cases. Hypoxia (100%) and early seizures (100%) were predominant among clinical findings with evoked potential changes in 50% of cases. In the assessment of the neuro development all the areas remained within normality parameters up to the conclusion of the present study. Conclusion: ultrasonography in association with Doppler can identify changes related to cerebral venous thrombosis and should be complemented with magnetic resonance imaging that is the gold standard for diagnosis in these cases.

    We reviewed the clinical and MRI findings in primary nerve-sheath tumours of the trigeminal nerve. We retrospectively reviewed the medical records, imaging and histological specimens of 10 patients with 11 primary tumours of the trigeminal nerve. We assessed whether tumour site, size, morphology or signal characteristics were related to symptoms and signs or histological findings. Histological proof was available for 8 of 11 tumours: six schwannomas and two plexiform neurofibromas. The other three tumours were thought to be schwannomas, because they were present in patients with neurofibromatosis type 2 and followed the course of the trigeminal nerve. Uncommon MRI appearances were observed in three schwannomas and included a large intratumoral haemorrhage, a mainly low-signal appearance on T2-weighted images and a rim-enhancing, multicystic appearance. Only four of nine schwannomas caused trigeminal nerve symptoms, including two with large cystic components, one haemorrhagic and one solid tumor. Of the five schwannomas which did not cause any trigeminal nerve symptoms, two were large. Only one of the plexiform neurofibromas caused trigeminal nerve symptoms. Additional neurological symptoms and signs, not related to the trigeminal nerve, could be attributed to the location of the tumour in three patients. (orig.)

    Bronchiectasis means a permanent abnormal dilatation off one or more large bronchi owing to destruction of the elastic and muscular components of the bronchial wall. Radiological study is the most important and mandatory procedure. Especially bronchography is essential for the definitive diagnosis of bronchiectasis and for the precise delineation of the type and extent of the disease. The radiological and clinical findings of 48 cases of bronchiectasis diagnosed by bronchography and treated at Chosun University Hospital during the 5 years from January 1980 to December 1984 were analyzed retrospectively. The results were as follows; 1. Among the 48 cases, 34 cases (70.8%) were male and 14 cases (29.2%) were female. Peak incidence was in second decade. 2. Chronic cough productive sputum and hemoptysis are main symptoms and others are chest pain, dyspnea and recurrent bouts of pneumonia. The most common physical sign is persistent moist rales over the involved area in 23 cases (47.9%). Others are no sign in 17 cases (35.4%), wheezing in 11 cases (22.9%) and digit clubbing in 3 cases (6.3%). 3. The presumed causes were composed of not known in 30 cases (62.5%)> and complications of measles in 7 cases (14.6%), pertussis in 5 cases (10.4%) and pneumonia in 4 cases (8.3%). Two cases were Kartagener's syndrome and unilateral hyperlucent lung. 4. Plain chest common radiological findings was accentuation of lung marking in 36 cases (85.7%), the others are include in order of frequency; pneumonic infiltration, linear radiolucencies, cystic radiolucencies, decreased affected lung volume, air-fluid, level and pleural thickening. 5. Bilateral bronchiectasis was demonstrated in 11 cases (22.9%) and the disease was much more often involved left lung than right. The most commonly involved lobe is left lower lobe, and the most common site of involvement was the posterior basal segment of the lower lobe. The type of bronchiectasis is cylindrical in 22 cases (45.8%), varicose in 11

    This study was performed to examine whether a clinical classification of different phenotypes of amelogenesis imperfecta could be discernible at the ultrastructural level. 17 primary teeth from 16 children with hypomineralization, hypomaturation, or hypoplastic variants of the disease were collected for histologic studies of the enamel by means of polarized light microscopy, scanning electron microscopy (SEM), and secondary ion mass spectrometry (SIMS). Polarization microscopy showed that the enamel was hypomineralized; in 6 teeth a wavy configuration of the enamel prisms also appeared. Three histomorphologic main types could be discerned. In 10 of the teeth extensive hypermineralization of the bulk of the enamel was found. 1 tooth had an unusually tick enamel with only a thin normally mineralized surface layer. SIMS images showed less pronounced signals from Ca 2+ and Na + , but with stronger signals from Cl - and CN - , representing the organic component of enamel. The SEM images showed an irregular prism pattern with marked interprismatic areas. Irrespective of the clinical appearance or the herediatary pattern the main findings were hypomineralized enamel with or without wavy bands. Neither of the analytical methods used in this paper distinguishes between the clinical phenotypes of amelogenesis imperfecta. 35 refs., 9 figs., 1 tab

    Neurofibromatosis is the commonest neuroectodermal disease. It is characterized by dysplasias and/or tumors of organs and tissues derived from the embryonic ectoderm, and most frequently presents with nervous system and cutaneous lesions. It can be classified as neurofibromatosis type 2 (NF-2 or bilateral acoustic neurofibromatosis). In order to assess clinical presentation of the disease and diagnostic value of Magnetic Resonance Imaging (MRI), the authors retrospectively evaluated the clinical records and the cranial MR studies of 21 patients with neurofibromatosis (18 with NF-1 and 3 with NF-2). Distinctive abnormalities between the two types were found in both clinical presentation and MR studies. Clinically, NF-1 patients presented most often with blindness, while NF-2 patients were deaf and had fewer cutaneous lesions. The evaluation of MR studies showed that NF-1 patients were more likely to be affected with intracranial gliomas, predominantly of the optic pathways. Moreover, foci of prolonged T2 relaxation were frequently observed, primarily in the globus pallidus of the basal ganglia and in the dentate nucleus of the cerebellum. Some of the foci in the globi pallidi exhibited increased signal intensity on T1-weighted images as well. NF-2 patients more frequently presented with bilateral acoustic schwannomas, meningiomas and cerebral white matter foci of prolonged T2 relaxation, but they did not have dentate and basal ganglia lesions. The authors conclude that as a rule the manifestations of NF-1 and NF-2 on cranial MRI are separate and distinct; they do not overlap. MRI is an useful clinical tool for the diagnosis and the follow-up of patients with neurofibromatosis

    Full Text Available Background: The aim of the study was to determine the correlation between clinical and echocardiographic findings and risk factors of patients with suspected acute pulmonary thromboembolism (PTE who underwent computed tomography pulmonary angiography (CTPA. Materials and Methods: In this cross-sectional study, 310 hospitalized patients aged >18 years with high clinical suspicion of PTE referred to imaging center of our hospital from different wards for CTPA were enrolled. The frequency of different clinical presentations, risk factors, items of Wells' criteria, and echocardiographic findings was compared in patients with and without PTE, which have been diagnosed according to the CTPA results. Results: PTE was diagnosed in 53 (17.1% of patients with suspected PTE. From clinical manifestations, tachypnea, pleuritic chest pain, and edema of lower extremities were significantly more frequent among patients with PTE (P < 0.05. Major surgery was the risk factor which was significantly more prevalent among patients with PTE (P < 0.05. Frequency of all criteria of Wells' criteria, except hemoptysis, was significantly higher in patients with PTE (P < 0.05. The frequency of all studied echocardiographic variables was significantly higher in patients with PTE (P < 0.05. Conclusion: It is suggested that we could use the results of this study for utilizing the diagnostic process of PTE in patients with highly clinical suspicion of PTE and providing more validated decision. Using the results of this study, we could identify high-risk patients and made appropriate risk assessment for better management of patients with suspected PTE as well as reduce the rate of unnecessary CTPA and its related adverse consequences.

    Athletic pubalgia is a frequently encountered syndrome for clinicians who treat active patients participating in a wide variety of athletic endeavors worldwide. Pathologies associated with this clinical scenario span anatomically from the pubic symphysis to the hip and include a myriad of poorly understood and incompletely described musculoskeletal entities, many of which are centered about the pubic symphysis and its tendinous attachments. In this article, we discuss the relevant anatomy and pathophysiology for the most frequently encountered of these disorders, using magnetic resonance (MR) images as a guide. We describe an MR imaging protocol tailored to clinical athletic pubalgia. We then review reproducible MRI patterns of pathology about the pubic symphysis, the rectus abdominis/adductor aponeurosis and the inguinal ring, as well as a group of clinically confounding entities remote from the symphysis but visible by MRI.

    To evaluate dynamic CT features and its clinical courses of eosinophilic hepatic abscess. Two-phase dynamic CT findings and the clinical courses of 13 pathologically proven cases of eosinophilic abscess were reviewed. All patients showed peripheral eosinophilia, and diagnoses were confirmed by ultrasound-guided biopsy(n=9) or operation(n=4). In two of the four patients who underwent segmental hepatectomy, worms of the species fasciola hepatica were detected. Follow-up CT scans after treatment with antibiotics or praziquantel were available in seven and eitht patients, respectively. All hepatic lesions were found in a subcapsular location or in contact with Glisson's capsule around the bile duct Arterial-dominant phase CT(n=11) demonstrated clusters of ill-defined low density masses without rim enhancement. Late-phase CT(n=13) more clearly depicted clustering lesions with enhancing rims and diminyution of the low-density area. Follow-up CT scans after treatment with antibiotics(n=7) showed no change in the lesions in three patients and slight shrinkage of the main mass with additional new lesions in four. On CT scans of nine patients performad after praziquantel therapy, hepatic masses were seen in all patients to be very slightly smaller after improvement of peripheral hypereosinophilia. Two-phase dynamic CT features appear to be helpful for the diagnosis of eosinophilic hepatic abscess in patients with peripheral eosinophilia. Parasitic infestation by Fasciola hepatica for example, is the presumed cause of such abscesses, though further studies are required

    To evaluate the mammographic and clinical features of bilateral breast cancer. We retrospectively reviewed clinical records(n=23) and mammograms (n=15) of 23 patients with bilateral breast cancer. Patients' age, location of the tumor and pathologic staging were determined from clinical records. Mammographic features were classified as spiculated mass, nonspiculated mass, mass with microcalcification, microcalcification only, asymmetric density, and normal. Of the 23 cases of bilateral breast cancer, 8(34.8%) were synchronous and 15(65.2%) were metachronous. Age at diagnosis of cancer in the first breast was between 27 and 59(mean 43) years ; there was no statistically significant difference in mean age between patients with synchronous and metachronous cancer. The mean interval between the diagnosis of each lesion of the metachronous pairs was 9.1 years. In 11 of 23 cases(48%), tumors were locaated in the same quadrant, and in the other 12 cases(52%), they were in different quadrant. At mammography, five of 15 metachronous cancers(33%) were similar in appearance and 10 pairs(67%) were different. In 4 of 23 cases(17%), cancer in the first breast was at stage 0 and stage 1, and in 13 of 23(57%), cancer in the second breast was at this same stage. In bilateral breast cancer, the two breasts frequently show different mammographic features. Cancer of the second breast was at an early stage; this suggest that regular examination and mammography are important and can allow early detection of contralateral breast cancer

    Purpose: To assess the clinical application and limitation of 3D spiral CT of the auditory ossicular chain and labyrinth. Methods: 3D reconstruction of the auditory ossicular chain and labyrinth, including multiplanar reformation (MPR), minimum or maximum intensity projection (MinIP or MaxIP) and shaded surface display (SSD), were performed with 1 mm slice thickness, 5 cm field of view and 0.1 mm reconstruction interval spiral CT in 14 normal subjects, 15 patients with middle ear diseases. Results: With use of 3D reconstruction images in 14 normal subjects, 13 cases of ossicular chain showed that the long process of the incus was parallel to the manubrium and projected inferomedian toward the cochlear promontory, the incus-stapedial joint was like a 'L-shape' structure, and in 8 cases of labyrinth reconstruction, the cochlea and the three semicircular canals were demonstrated. 9 cholesteatomas of 13 chronic otitis media demonstrated destruction of ossicular chain of varying degrees. In 2 cases with congenital abnormality, ossicle dysplasia was seen. Conclusion: 3D CT is a useful technique for evaluating anatomic malformations and diseases of middle and inner ear, but there are still few pitfalls

    The defectography is an examination of the anorectal function in defecatory disorder. The defecography has a diagnostic impact on disease, which only emerge during defecation as intussusception, enterocele, prolapse or sphincter dysfunction. Other findings as rectocele or descending pelvic floor are ambiguous concerning clinical relevance. The interpretation of defecography should include patient's history and clinical findings and - if available -endoscopic and manometric findings. (orig.) [de

    Background Seizure disorder is the most common childhood neurologic condition and a major public health concern. Identification of the underlying seizure etiology helps to identify appropriate treatment options and the prognosis for the child. Objective This study was conducted to investigate the clinical profile, causes and electroencephalogram findings in children with seizure presenting to a tertiary center in Kavre district. Method This was a hospital based prospective study carried out in the Department of Pediatrics, Dhulikhel Hospital, Kavre from 1st April 2015 to 31st March 2016. Variables collected were demographics, clinical presentations, laboratory tests, brain imaging studies, electroencephalography, diagnosis and outcome. Result Study included 120 (age 1 month to 16 years) children attending Dhulikhel Hospital. Majority of the patients were male (60.84%). Age at first seizure was less than 5 years in 75.83% of children. Seizure was generalized in 62.50%, focal in 31.67% and unclassified in 5.83%. Common causes of seizure were - Primary generalized epilepsy (26.66%), neurocysticercosis (10%) and hypoxic injury (6.6%) which was diagnosed in the perinatal period. Febrile seizure (26.66%) was the most common cause of seizure in children between 6 months to 5 years of age. Neurological examination, electroencephalography and Computed Tomography were abnormal in 71.66%, 68.92% and 58.14% cases respectively. Seizure was controlled by monotherapy in 69.16% cases and was resistant in 7.50% of the cases. Conclusion Primary generalized epilepsy and febrile seizure were the most common causes of seizures in children attending Dhulikhel Hospital. Electroencephalogram findings help to know the pattern of neuronal activity. Response to monotherapy was good and valproic acid was the most commonly used drug.

    Background: Although pulmonary alveolar proteinosis (PAP) and exogenous lipoid pneumonia (ELP) require different treatment strategies, both manifest as a crazy-paving pattern on CT and often have similar clinical manifestations and radiologic features. Purpose: To investigate the clinical features and high-resolution computed tomography (HRCT) findings of PAP and ELP showing the crazy-paving pattern. Material and Methods: The clinical features and HRCT findings of eight patients with pathologically proven PAP and six patients with pathologically proven ELP showing the crazy-paving pattern were retrospectively evaluated. Two radiologists analyzed the HRCT findings of PAP and ELP in consensus in terms of the presence, severity, and extent of illdefined centrilobular nodules, consolidations, ground-glass opacities (GGOs), reticulations, and the crazy-paving pattern. Results: With respect to the clinical features of these two diseases, all patients with ELP were retrospectively found to have a history of oil ingestion. In terms of the HRCT findings, ill-defined centrilobular nodules were seen in five of six patients (83%) with ELP, whereas they were not present in any patient with PAP (P=0.003). Consolidation was also more frequently present in patients with ELP (83%) than in those with PAP (11%), which was statistically different (P=0.0265). In terms of the severity and extent, the crazy-paving pattern and reticulations on HRCT were significantly more extensive and severe in patients with PAP than in those with ELP. Conclusion: PAP and ELP with the crazy-paving pattern have several distinctive characteristics with respect to their HRCT findings as well as history of oil ingestion, and can therefore be distinguished from one another

    Full Text Available To evaluate the correlation of clinical, laboratory, and pathological features at pre-sentation of focal segmental sclerosis (FSGS, we reviewed in a cross sectional study the patholo-gical findings of kidney biopsies in 64 cases of primary FSGS, and correlated them with the clinical and laboratory data obtained at the time of the biopsies. The data included blood pressure, glome-rular filtration rate (GFR, serum albumin, and the level of proteinuria. The mean level of serum crea-tinine was significantly higher in the biopsies′ findings of synechiae (adhesions in the Bowman′s capsule, interstitial fibrosis, and global scars (P< 0.05, and mean level of GFR was significantly lower with the presence of interstitial fibrosis (P< 0.05. Furthermore, there was a positive correlation between the level of serum creatinine and global sclerosis (r= 2.21, P= 0.04, and a negative correlation between the level of GFR and global sclerosis(r= 2.01, P= 0.02. All the patients with renal insufficiency had interstitial fibrosis in their biopsies in comparison of only the 24 patients (48% of the group without renal insufficiency (P< 0.05. There was no significant difference bet-ween patients with and without hypertension and nephritic-ranged proteinuria. We conclude that we found a correlation of renal insufficiency in primary FSGS patients with interstitial fibrosis, global scars and the synechiae of Bowman′s capsule in their biopsies.

    Accessory ossicles and sesamoid bones are frequent findings in routine radiographs of the ankle and foot. They are commonly considered fortuitous and unrelated to the patient's complaint; however, they may eventually cause painful syndromes or degenerative changes in response to overuse and trauma. They may also suffer or simulate fractures. Our aim was to review, illustrate and discuss the imaging findings of some of the more frequent accessory ossicles and sesamoid bones of the ankle and foot region, with particular emphasis on those that may be of clinical significance or simulate fractures.

    Full Text Available Background: Managing dental caries in young children is demanding due to the elusions present on the right diagnostic criteria for treatment. The present study evaluated the histological status of pulp tissues extracted from primary second molar with caries involvement. Histological findings are correlated with clinical and radiographic assessment. Materials and Methods: Simple experimental study was conducted on upper or lower second primary molars with occlusal (22 teeth or proximal (22 teeth dental caries. Selected children were below 6 years of age. Percentage of caries involvement, residual dentin thickness (RDT, radiographic assessment of interradicular and periapical areas, clinical caries depth and signs and symptoms are the parameters considered for comparing with the histological findings. The specimens were grouped based on the nature of the inflammatory process as acute or chronic. The data were analyzed by Student t-test to compare histological types of inflammation with clinical parameters. P value < 0.05 was considered as significant. Results: Four cases revealed severe acute inflammation in coronal and relatively mild acute inflammation in radicular pulp. In the rest of the specimen coronal and radicular pulp had similar acute or chronic inflammatory changes. Histological evidence of pulpitis correlated with dental caries depth of ≥80%, RDT of ≤1 mm, radiographic rarefactions in the interradicular regions and symptoms of pain. Conclusion: Primary second molars with more than two-third caries involvement with symptoms of pain histologically showed inflammation of both coronal and radicular pulp tissues in all cases.

    We analyzed the correlation of clinical and radiological findings in the diagnosis of large cervical and retrosternal nodular goitres. Fourteen symptomatic patients were studied (12 female and 2 male). Nine of them had retrosternal goitre. All underwent computed tomography (CT) of the neck and upper mediastinum, thyroid scintigraphy using Tc-99m-pertechnetate and contrast radiology of the oesophagus. Problems with respiration (stridor) were present in five patients, but four of them had CT findings of tracheal compression. The other nine patients had no respiratory problems, and CT revealed tracheal compression in two cases. Nine patients had the dislocation of the trachea on CT. Dysphagia was present in eight cases but only three patients had radiological signs of oesophageal narrowing. These patients also had the dislocation of the oesophagus, revealed by contrast radiology, just as five others without any swallowing problems. The results demonstrate that all patients with respiratory problems do not necessary have tracheal compression (indicating the possible affection of the phrenic nerve). On the other hand, some patients can have tracheal narrowing without any respiratory problems. (author)

    The clinical courses and CT scan findings of 12 cases of supratentorial ependymoma and ependymoblastoma were reviewed. The age of the patient of ependymoma ranged from 3 years to 34 years, with an average age of 16 years. The follow-up time ranged from 2 months to 9 years and 10 months. All of the six patients are still alive. The age of the patients of ependymoblastoma ranged from 7 months to 34 years, with an average age of 17 years. During the follow-up period from 2 weeks to 6 years and 4 months, four patients died. Supratentorial ependymomas and ependymoblastomas show the following characteristic features of CT scans: 1. Calcification: The incidence of calcification was 50% in ependymoma-group, and 100% in ependymoblastoma-group. 2. Cyst formation, ring-enhancement: The cyst formation was noticed in both groups. In ependymoma-group a smooth ring-enhancement pattern and the strongly enhanced mural nodule-like contour were found, but in ependymoblastoma-group, the cyst wall was enhanced in irregular shape. 3. Perifocal edema and mass effect: Considerable mass effect was noticed in both groups. Perifocal edema was slight in many cases of ependymoma-group, but mostly prominent in ependymoblastoma-group. 4. CT scan findings of recurrent tumor: In ependymoma-group, recurrent tumor showed the same characteristics of CT scan as the initial ones. In ependymoblastoma-group, cystic portion decreased in size and irregular shaped solid portion increased in recurrence. (author)

    We tried to assess retrospectively thin-section CT findings of Churg-Strauss syndrome (CSS) in 25 patients and to compare these findings with clinical and histopathologic findings. Of 25 patients, 19 (76%) had parenchymal abnormalities at CT; small nodules (n = 12; 63%), ground-glass opacity (n = 10; 53%), bronchial wall thickening (n = 10; 53%), and consolidation (n = 8; 42%). Parenchymal abnormalities (n = 19) were categorizable as an airway pattern in 11 and an airspace pattern in eight. Patients with an airway pattern (n = 5) had obstructive (n = 3) or combined (n = 2) PFT results, whereas those with an airspace pattern (n = 4) had restrictive (n = 3) or obstructive (n = 1) results. Parenchymal opacities at CT corresponded histologically to areas of eosinophilic pneumonia, necrotizing granulomas, and granulomatous vasculitis; small nodules to eosinophilic bronchiolitis and peribronchiolar vasculitis; and bronchial wall thickening to airway wall eosinophil and lymphocyte infiltration. Patients with airspace pattern responded more readily to treatment than those with airway pattern. CT shows lung parenchymal abnormalities in about three-quarters of CSS patients and these abnormalities can be categorized as airspace or airway patterns. This classification helps predict PFT data, underlying histopathology, and treatment response. (orig.)

    Objective: To evaluate the ability of CT virtual endoscopy (CTVE) in visualization of auditory ossicular chain and its clinical application. Methods: CTVE of auditory ossicular chain was performed on GE HiSpeed CT/i with 1.0 mm slice thickness at pitch 1.0, bone algorithm, 9.6 cm FOV, and 0.1 mm reconstruction interval in 10 normal subjects and 21 patients with middle ear diseases, 14 of them were proved by operation. The threshold values for normal and abnormal auditory ossicular chain were -600--200 HU and 50-300 HU respectively. Results: CTVE could clearly demonstrate the shape, size, and relation of the normal auditory ossicular chain. A visualization rate of malleus, incus, and incudomalleal articulation was 100%, and was 32% for the stapedial foot plate. However, in only 21% could the anterior and posterior crura of stapes be distinguished. Cholesteatoma was found in 12 cases with chronic otitis media, in which CTVE demonstrated varying degrees of destruction of the auditory ossicle. In 1 case with congenital anomaly, ossicle dysplasia was seen. Conclusion: CTVE being a new, non-invasive method for demonstrating the three-dimensional image of auditory ossicular chain is useful in evaluating diseases of the ear, especially the auditory ossicles

    Hippocampal sclerosis (HS) is a common pathology in MTLE, patients may show different surgical outcomes and clinical features. The 2013 ILAE classification subdivides HS into 3 types (HS type 1: severe neuronal loss and gliosis predominantly in CA1 and CA4 regions; - HS type 2: CA1 predominant; HS type 3: CA4 predominant) and includes "gliosis only, as no-HS". The association of clinical and electrophysiological findings with different HS types has not been reported previously in detail. 48 patients who had undergone temporal lobectomy with amygdalohippocampectomy due to mesial TLE-HS between February 2014 and February 2016 were included. The patients were divided into five groups: patients with HS ILAE type 1, HS ILAE type 2, HS ILAE type 3, FCD type IIIa, or gliosis/no HS. The correlation between HS ILAE types and clinical/EEG findings in patients with MTLE due to HS was investigated. Of the 48 patients 30 were male. In 23 patients, the resection was on the left side (48%). Three patients had only gliosis, 25 patients had HS ILAE type 1, 7 had HS ILAE type 2, and 4 had HS ILAE type 3. Nine of the 48 patients had cortical lamination abnormalities in the temporal lobe associated with HS (FCD type IIIa). All patients were seizure free for early follow up. There was no association between type of HS in terms of duration of epilepsy, onset age of epilepsy, lateralized or localized semiological findings, or interictal/ictal EEG findings. Family history of epilepsy or SGTCSs were statistically more frequent in patients with types 2 and 3 HS and status epilepticus was more frequent in patients with HS-FCD type IIIa. The patients with HS types 2 and 3 have more frequent SGTCS or status epilepticus as well as increased family history of epilepsy. These findings can be helpful in understanding the epileptogenicity-prognoses of HS. Copyright © 2016 Elsevier B.V. All rights reserved.

    To identify associations between clinical symptoms of temporomandibular joint disorders and radiographic findings. Two hundred four adult patients (156 women, 48 men, mean age 40 years) with temporomandibular joint (TMJ) pain/sounds or changes in mandibular motion were examined according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Bilateral sagittal corrected TMJ tomograms in closed and open positions were assessed for the presence of flattening, erosion, osteophytes, and sclerosis in the joint components and the range of mandibular motion. Logistic regression analyses were performed with the radiographic findings as the dependent variables and the following clinical variables as independent variables: opening pattern, maximal jaw opening, TMJ sounds, number of painful muscle/TMJ sites, duration of pain, presence of arthritic disease, depression and somatization scores, graded chronic pain, and age and gender. Coarse crepitus on opening/closing (odds ratio [OR] > or = 3.12), on lateral excursions (odds ratio > or = 4.06), and on protrusion (OR > or = 5.30) was associated with increased risk of degenerative findings in tomograms. A clinical diagnosis of osteoarthritis increased the risk of radiographic findings (OR > or = 2.95) and so did increasing age (OR > or = 1.03 per year) and the female gender (OR > or = 2.36). Maximal assisted opening and maximal opening without pain (position (OR > or = 2.60). No other significant associations were observed. Age, gender, and coarse crepitus, but no pain-related variables, were associated with increased risk of degenerative findings in TMJ tomograms. Maximal opening < 40 mm was associated with a posterior condyle-to-articular tubercle relation on opening.

    The aim of this study was to compare the preoperative findings of abdominal/pelvic CT and MRI with the preoperative clinical International Federation of Obstetrics and Gynecology (FIGO) staging and postoperative pathology report in patients with primary cancer of the cervix. Thirty-six patients with surgical-pathological proven primary cancer of the cervix were retrospectively studied for preoperative staging by clinical examination, CT, and MR imaging. Studied parameters for preoperative staging were the presence of tumor, tumor extension into the parametrial tissue, pelvic wall, adjacent organs, and lymph nodes. The CT was performed in 32 patients and MRI (T1- and T2-weighted images) in 29 patients. The CT and MR staging were based on the FIGO staging system. Results were compared with histological findings. The group is consisted of stage 0 (in situ):1, Ia:1, Ib:8, IIa:2, IIb:12, IIIa:4, IVa:6, and IVb:2 patients. The overall accuracy of staging for clinical examination, CT, and MRI was 47, 53, and 86%, respectively. The MRI incorrectly staged 2 patients and did not visualize only two tumors; one was an in situ (stage-0) and one stage-Ia (microscopic) disease. The MRI is more accurate than CT and they are both superior to clinical examination in evaluating the locoregional extension and preoperative staging of primary cancer of the cervix. (orig.)

    Objective: Large endolymphatic duct and sac syndrome (LEDS) is known as the most common kind of inner ear malformations, which is radiologically detectable. Nevertheless, nowadays many questions are not fully cleared and LEDS is relatively unknown among general radiologists. The aim of this study was to evaluate the incidence of LEDS in the own patient population and to present our experiences regarding imaging findings, clinical presentation and follow up. Materials and methods: Based on a complete recording of all patients, sent from ENT department to radiology, we identified all radiological diagnosed cases of inner ear malformations including LEDS and all patients in whom an inner ear malformation was clinically suspected. The retrospective study included clinical records, HR-CT and MRI performed between 1994 and 2002. Results: Among 169 patients (338 ear), 17 of patients (median age: 12 years) and 28 ears, respectively, had enlarged endolymphatic structures. In 10 patients - 6% - (15 ears), no other abnormalities were detected, called isolated LEDS, seven patients showed additional inner ear abnormalities. One patient showed a labyrinthine hemorrhage after sudden hearing loss. Audiometric data revealed sensorineural hearing loss in 22 ears, deafness in 5 ears and normal hearing in 1 case of 28 ears. In 10 (67%) of 15 ears with isolated LEDS, the hearing loss was downward-fluctuating progressive. Twelve patients (eight with isolated LEDS) had partly repeated sudden hearing losses. A trigger for worsening of hearing was found in five patients. A correlation between the severity of morphological changes on imaging and the degree of hearing disturbances could not be detected. Only four young patients underwent a radiological examination within the first or second year after onset of hearing loss. Three patients received a cochlear implant. Conclusions: LEDS might be the cause of progressive hearing loss and repeated acute hearing losses in children and young

    Conclusion Association of these findings with an expanded clinical definition of Joubert is warranted. The clinical subtypes of JS may be associated with specific types of mutations in the causative genes. This report, which evaluates the findings in a relatively young cohort, provides a unique opportunity to consider the earliest manifestations of JS that may lead to early recognition and appropriate genetic testing to confirm the diagnosis. Clinical findings beyond those identified in this report and by prior publications should be evaluated as potentially independent of the primary genetic condition rather than assuming that each new finding is part of the same syndrome.

    Full Text Available Background and Design: Morphea is an inflammatory skin disease seen more frequently than systemic sclerosis in pediatric patients. Important functional deficiencies and cosmetic deformities may develop especially due to linear morphea. Patients may have accompanying extracutaneous involvement, family history of rheumatologic diseases and abnormalities in laboratory parameters like positive ANA and RF. It is important to evaluate pediatric patients accordingly and to carry out further examinations.Data about pediatric morphea in Turkish population could not be found in the literature. We aimed to evaluate epidemiological, clinical and laboratory findings, to compare the data with those in the literature and to propose a model for Turkish pediatric morphea which can be supported by future multicenter national studies. Materials and Methods: Fourteen pediatric morphea patients, 3 males and 11 females under the ageof 18, followed up at Uludag University, Medical Faculty, Dermatovenereology Department between 2000-2010 were enrolled in the study. Inclusion criterion was age under 18 years at diagnosis. Epidemiological, clinical and laboratory findings were analyzed retrospectively. Results: Only 3 patients were males. The mean age at disease onset was 9.5 years. The mean duration of disease was 21 months. Most frequent type was linear morphea. Two patients had contracture, one had shortness in the left lower extremity, and 4 patients had livedo reticularis. Raynaud’s phenomenon was positive in one case. Trauma and sunburn were the trigger factors detected. Behcet’s disease was reported in the father of one patient. One case was RF positive. Five patients had positive ANA in titers of 1/100, while a patient with generalised morphea had significantly higher titer (1/1000. Antihistone antibodies were positive in one patient and 2 cases were Lyme IgM positive.Conclusion: Early diagnosis and therapy are important since childhood morphea can cause

    Objective: To assess the relationship between left anterior descending (LAD) coronary artery myocardial bridging detected by 64-slice computed tomography (CT) and clinical findings. Methods: 221 consecutive patients were examined with coronary 64-slice CT angiography. 21 patients with coronary stenosis >50% were excluded. The length, depth, and luminal narrowing of LAD myocardial bridges during systole and diastole were measured. CT findings were compared with the treadmill ECG-stress test, and clinical symptoms. Results: Myocardial bridges of the LAD were found in 23% of patients (51/221) (length, 14.9 {+-} 6.5 mm; depth, 2.6 {+-} 1.6 mm). A significant difference was noted between the LAD luminal diameter before the intramyocardial course and intramyocardially, for both diastole and systole (p < 0.001); with a higher diameter reduction of 27% for end-systole compared to end-diastole with 15% (p = 0.006). Systolic LAD intramyocardial luminal narrowing >50% was found in 3/25 (8%). 30/51 (59%) of bridges were 'deep' (>2 mm myocardial depth), 21/51 (41%) were 'superficial'. The prevalence of a positive ECG-stress tests for the anterior myocardial region was significantly higher in patients with LAD myocardial bridges (34/50; 68%) compared to those without (28/144; 19.4%) (p < 0.001). There was no difference between 'superficial' and 'deep' LAD myocardial bridges in regard to a positive treadmill ECG-stress test. Typical angina was rare with 6%. Conclusion: LAD myocardial bridges are common findings and can possibly explain a positive exercise ECG-stress test for anterior myocardial ischemia. Intramyocardial LAD segments show mild-to-moderate luminal narrowing at rest, which is higher during end-systolic phase.

    To analyse the clinical features and CT findings of pyogenic liver abscess due to Klebsiella pneumoniae, and to compare the findings with those of cases in which abscesses were caused by other pathogens. Twenty-one cases of pyogenic liver abscess were assigned to either the Klebsiella or the non-Klebsiella group, and the patients' past medical history and intra-abdominal abnormalities such as calculus or malignancy were reviewed. Laboratory data such as alkaline phosphatase (ALT), SGOT and SGPT levels were analyzed, and on the basis of the CT findings, decisions were reached as to (a) whether abscesses were single or multiple contiguous or discontiguous, uniloculated or multiloculated; and (b) the presence or absence of gas, hepatic parenchymal enhancement, peripheral rim enhancement, and extrahepatic abnormality. For statistical analysis, fisher's exact test was used. Among 21 abscesses, Klebsiella pneumoniae was the most common pathogen (n=11). The others were Pseudomonas (n=3), E.coli (n=2), Enterococcus (n=2), G. (+) cocci (n=2) and polymicrobial (n=1). Diabetes mellitus was more common among patients in the Klebsiella group, among whom a multiloculated single cavity was a frequent finding. Five patients in the non-Klebsiella group experienced biliary tract obstruction, which was not demonstrated in the Klebsiella group. Hepatic parenchymal enhancement was more common in the non-Klebsiella group. In case of pyogenic liver disease, especially where diabates mellitus is involved, Klebsiella pneumoniae is a major pathogen. Significant CT findings of Klebsiella liver abscess included a multiloculated single cavity, rare biliary tract obstruction, and little hepatic parenchymal enhancement

    This study was performed to examine whether a clinical classification of different phenotypes of amelogenesis imperfecta could be discernible at the ultrastructural level. 17 primary teeth from 16 children with hypomineralization, hypomaturation, or hypoplastic variants of the disease were collected for histologic studies of the enamel by means of polarized light microscopy, scanning electron microscopy (SEM), and secondary ion mass spectrometry (SIMS). Polarization microscopy showed that the enamel was hypomineralized; in 6 teeth a wavy configuration of the enamel prisms also appeared. Three histomorphologic main types could be discerned. In 10 of the teeth extensive hypermineralization of the bulk of the enamel was found. 1 tooth had an unusually tick enamel with only a thin normally mineralized surface layer. SIMS images showed less pronounced signals from Ca[sup 2+] and Na[sup +], but with stronger signals from Cl[sup -] and CN[sup -], representing the organic component of enamel. The SEM images showed an irregular prism pattern with marked interprismatic areas. Irrespective of the clinical appearance or the herediatary pattern the main findings were hypomineralized enamel with or without wavy bands. Neither of the analytical methods used in this paper distinguishes between the clinical phenotypes of amelogenesis imperfecta. 35 refs., 9 figs., 1 tab.

    To determine whether there is a difference in frequency and clinical relevance of incidental findings detected by total-body computed tomography scanning (TBCT) compared to those by the standard work-up (STWU) with selective computed tomography (CT) scanning. Trauma patients from five trauma centres were randomized between April 2011 and January 2014 to TBCT imaging or STWU consisting of conventional imaging with selective CT scanning. Incidental findings were divided into three categories: 1) major finding, may cause mortality; 2) moderate finding, may cause morbidity; and 3) minor finding, hardly relevant. Generalized estimating equations were applied to assess differences in incidental findings. In total, 1083 patients were enrolled, of which 541 patients (49.9 %) were randomized for TBCT and 542 patients (50.1 %) for STWU. Major findings were detected in 23 patients (4.3 %) in the TBCT group compared to 9 patients (1.7 %) in the STWU group (adjusted rate ratio 2.851; 95%CI 1.337-6.077; p < 0.007). Findings of moderate relevance were detected in 120 patients (22.2 %) in the TBCT group compared to 86 patients (15.9 %) in the STWU group (adjusted rate ratio 1.421; 95%CI 1.088-1.854; p < 0.010). Compared to selective CT scanning, more patients with clinically relevant incidental findings can be expected by TBCT scanning. (orig.)

    Objective. To describe the clinical, radiological and pathological findings in a patient with methadone-induced delayed posthypoxic encephalopathy (DPHE). Case Report. A Thirty-eight-year-old man was found unconscious for an unknown duration after methadone and diazepam ingestion. His initial vitals were temperature 104 degree Fahrenheit, heart rate 148/minute, respiratory rate 50/minute, and blood pressure 107/72 mmhg. He developed renal failure, rhabdomyolysis, and elevated liver enzymes which resolved completely in 6 days. After 2 weeks from discharge he had progressive deterioration of his cognitive, behavioral and neurological function. Brain MRI showed diffuse abnormal T2 signal in the corona radiata, centrum semiovale, and subcortical white matter throughout all lobes. Extensive work up was negative for any metabolic, infectious or autoimmune disorder. Brain biopsy showed significant axonal injury in the white matter. He was treated successfully with combination of steroids and antioxidants. Follow up at 2 year showed no residual deficits. Conclusion. Our observation suggests that patients on methadone therapy should be monitored for any neurological or psychiatric symptoms, and in suspected cases MRI brain may help to make the diagnosis of DPHE. A trial of steroids and antioxidants may be considered in these patients.

    The purpose of this study was to describe the CT findings and clinical outcomes of nineteen patients with acute intramural hematoma (IMH) of the ascending aorta. Six patients underwent surgery on the emergency basis (3 patients) due to cardiac tamponade (n=2) and dilated aorta (n=1), and on the elective basis (3 patients) due to patent and enlarging false lumen. Among the 13 patients with medical management, four patients died from complications of IMH during the follow-up period (2 days-2.5 years). Transition to aortic dissection or enlargement of an intimal tear was noted in 5 patients (31%) in 1 to 6 weeks after onset. Three patients died of causes not related to IMH. Six patients had been alive 2 to 9 years after onset. Retrospective review revealed 10 patients (53%) as possible surgical candidates, and the other 9 patients as medically treated patients in the long-term follow-up. The surgical group showed cardiac tamponade or shock in 6 patients on admission and had pericardial effusion in all the patients on the initial CT scan. In the patients with acute IMH of the ascending aorta, surgery should be considered for severe clinical symptoms, pericardial effusion and large size of the ascending aorta (more than 4 cm) on CT scan, and for converting to a typical type A aortic dissection. CT scan had a major role in making an early diagnosis, in depicting a dangerous sign, and in monitoring its progression or resolution of IMH. (author)

    Full Text Available Objective: Morphea, also known as localized scleroderma, is a rare skin disease of unknown pathogenesis, characterized by fibrosis in the skin and subcutaneous tissue. In this study, we aim to evaluate the demographic features, clinical characteristics, laboratory findings, and response to treatment in patients diagnosed with morphea. Materials and Methods: The findings of fifty eight patients diagnosed with morphea were retrospectively evaluated between 1995-2011. All patients' clinical symptoms, concomitant diseases, symptoms, immunological features and presence of peripheral eosinophilia were investigated. Treatment methods, response to therapy of 40 patients whose treatment continued for 2-12 months were examined. Fourty nine patients (84.5% were female and 9 patients (15.5% were male of 58 patients who were diagnosed with morphea. The mean age of patients was 42.33±18.44 years (range: 7-75 years. Diagnosis was made histopathologically in all cases. Borrelia antibodies were negative in all patients enrolling the study. Thirty six patients (62.1% had plaque type, 17 patients (29.3% had generalized type, 3 patients (5.2% had mixed type (linear + plaque and 2 patients (3.4% had linear type of morphea. ANA was found to be positive in 12 (26.2% of 46 patients. Considering the relationship between the clinical types of morphea with ANA, 38.5% of plaque type, 53.8% of generalized type, 7.7% of mixed type patients showed ANA positivity. ANA positivity was statistically significant in patients with generalized morphea (p=0.027. Peripheral eosinophilia was detected in one case in whom lesions were generalized (2.1%. Colchicine therapy was given to 23 cases. Complete and partial response rates are 47.8% and 26.1%, respectively. However, 17.4% of patients remained stable and progression was noted in 8.7% of the cases. Conclusion: In conclusion, plaque type morphea is the most common type of morphea.

    Full Text Available The ryanodine receptor 1-related congenital myopathies (RYR1-RM comprise a spectrum of slow, rare neuromuscular diseases. Affected individuals present with a mild-to-severe symptomatology ranging from proximal muscle weakness, hypotonia and joint contractures to scoliosis, ophthalmoplegia, and respiratory involvement. Although there is currently no FDA-approved treatment for RYR1-RM, our group recently conducted the first clinical trial in this patient population (NCT02362425. This study aimed to characterize novel RYR1 variants with regard to genetic, laboratory, muscle magnetic resonance imaging (MRI, and clinical findings. Genetic and histopathology reports were obtained from participant’s medical records. Alamut Visual Software was used to determine if participant’s variants had been previously reported and to assess predicted pathogenicity. Physical exams, pulmonary function tests, T1-weighted muscle MRI scans, and blood measures were completed during the abovementioned clinical trial. Six novel variants (two de novo, three dominant, and one recessive were identified in individuals with RYR1-RM. Consistent with established RYR1-RM histopathology, cores were observed in all biopsies, except Case 6 who exhibited fiber-type disproportion. Muscle atrophy and impaired mobility with Trendelenburg gait were the most common clinical symptoms and were identified in all cases. Muscle MRI revealed substantial inter-individual variation in fatty infiltration corroborating the heterogeneity of the disease. Two individuals with dominant RYR1 variants exhibited respiratory insufficiency: a clinical symptom more commonly associated with recessive RYR1-RM cases. This study demonstrates that a genetics-led approach is suitable for the diagnosis of suspected RYR1-RM which can be corroborated through histopathology, muscle MRI and clinical examination.

    Diagnosis of HIV infection during early stages is mandatory to catch up with the challenge of limiting HIV viral replication and reservoirs formation, as well as decreasing HIV transmissions by immediate cART initiation. Aims were to describe (a) virological characteristics of AHI identified, (b) epidemiological and clinical factors associated with being diagnosed with AHI. Cross-sectional, retrospective study. All individuals diagnosed with AHI according to Fiebig's staging between Jan 2013 and Mar 2014 at the INMI "L. Spallanzani" were included. Serum samples reactive to a fourth generation HIV-1/2 assay (Architect HIV Ag/Ab Combo, Abbott) were retested with another fourth generation assay (VIDAS DUO HIV Ultra, Biomérieux) and underwent confirmation with HIV-1 WB (New Lav I Bio-Rad) and/or with Geenius confirmatory assay (Bio-Rad). WHO criteria (two env products reactivity) were used to establish positivity of confirmatory assays. In case of clinically suspected AHI, HIV-1 RNA (Real time, Abbott) and p24 assay (VIDAS HIV P24 Bio-Rad) were also performed. Avidity test was carried out, on confirmed positive samples lacking p31 reactivity, to discriminate between recent (true Fiebig V phase) and late infections; to avoid possible misclassifications, clinical data were also used. Demographic, epidemiological, clinical and laboratory data are routinely, and anonymously recorded in the SENDIH and SIREA studies. During the study period, we observed 483 newly HIV diagnosed individuals, of whom 40 were identified as AHI (8.3%). Fiebig classification showed: 7 stage II/III, 13 stage IV, 20 stage V. Demographic, epidemiological, and clinical characteristics of patients are shown in the Table. Overall, the study population had a median S/Co ratio at fourth generation EIA (Architect) of 49.50 (IQR, 23.54-98.05): values were significantly lower in Fiebig II-IV than in Fiebig V (38.68 [IQR, 20.08-54.84] vs 75.72 [IQR, 42.66-249.80], p=0.01).

    To characterize the morphology and imaging findings of femoral head subchondral insufficiency fractures (SIF), and to investigate clinical outcomes in relation to imaging findings. Fifty-one patients with hip/pelvis magnetic resonance (MR) images and typical SIF characteristics were identified and reviewed by two radiologists. Thirty-five patients had follow-up documentation allowing assessment of clinical outcome. Subgroup comparisons were performed using regression models adjusted for age and body mass index. SIF were frequently associated with cartilage loss (35/47, 74.5 %), effusion (33/42, 78.6 %), synovitis (29/44, 66 %), and bone marrow oedema pattern (BMEP) (average cross-sectional area 885.7 ± 730.2 mm{sup 2}). Total hip arthroplasty (THA) was required in 16/35 patients, at an average of 6 months post-MRI. Compared to the THA cohort, the non-THA group had significantly (p < 0.05) smaller overlying cartilage defect size (10 mm vs. 29 mm), smaller band length ratio and fracture diameters, and greater incidence of parallel fracture morphology (p < 0.05). Male gender and increased age were significantly associated with progression, p < 0.05. SIF were associated with synovitis, cartilage loss, effusion, and BMEP. Male gender and increased age had a significant association with progression to THA, as did band length ratio, fracture diameter, cartilage defect size, and fracture deformity/morphology. (orig.)

    Full Text Available Reported cases of dengue are rising in South Australia (SA in travellers returning from dengue-endemic regions. We have undertaken a retrospective analysis to identify the clinical and laboratory characteristics of patients returning to SA with suspected dengue virus (DENV infection. From 488 requests, 49 (10% were defined by serology as acute dengue, with the majority of patients (75% testing as non-structural protein 1 (NS1 and/or IgM positive. Dengue was most commonly acquired in Indonesia (42.9% with clinical features of fever (95%, headache (41% and myalgia/arthralgia (56%. The presence of rash (36% and laboratory findings of neutropenia, leukopenia, thrombocytopenia, but not elevated C-reactive protein, were distinct from findings in DENV-seronegative patients. Available dengue seropositive samples were analysed by RT-PCR, with 14/32 (43.8% positive by a serotype non-specific DENV assay, but 28/32 positive (87.5% when also assessed by serotype-specific RT-PCR. Serotype analysis revealed the predominance of DENV-1 and DENV-2 and the presence of DENV-3, but not DENV-4 or Zika virus (ZIKV. Thus, dengue in returned travellers in SA presents in a manner consistent with World Health Organization (WHO definitions, with symptoms, travel history and laboratory results useful in prioritising the likelihood of dengue. This definition will assist the future management in DENV-non-endemic regions, such as SA.

    The National Cancer Institute (NCI)-funded cooperative group cancer clinical trial system develops experimental therapies and often collects samples from patients for correlative research. The cooperative group bank (CGB) system maintains biobanks with a current policy not to return research results to individuals. An online survey was created, and 10 directors of CGBs completed the surveys asking about understanding and attitudes in changing policies to consider return of incidental findings (IFs) and individual research results (IRRs) of health significance. The potential impact of the 10 consensus recommendations of Wolf et al. presented in this issue are examined. Reidentification of samples is often not problematic; however, changes to the current banking and clinical trial systems would require significant effort to fulfill an obligation of recontact of subjects. Additional resources, as well as a national advisory board would be required to standardize implementation.

    Totally endoscopic ear surgery is a relatively new method for managing chronic ear disease. This study aimed to test the null hypothesis that open and endoscopic approaches have similar direct costs for the management of attic cholesteatoma, from an Australian private hospital setting. A retrospective direct cost comparison of totally endoscopic ear surgery and traditional canal wall up mastoidectomy for the management of attic cholesteatoma in a private tertiary setting was undertaken. Indirect and future costs were excluded. A direct cost comparison of anaesthetic setup and resources, operative setup and resources, and surgical time was performed between the two techniques. Totally endoscopic ear surgery has a mean direct cost reduction of AUD$2978.89 per operation from the hospital perspective, when compared to canal wall up mastoidectomy. Totally endoscopic ear surgery is more cost-effective, from an Australian private hospital perspective, than canal wall up mastoidectomy for attic cholesteatoma.

    The purpose of our study was to retrospectively evaluate the prevalence and clinical relevance of positive abdominal and pelvic CT findings for patients 65 years of age and older, when compared with all other scanned adult Emergency Department (ED) patients, at a single tertiary care hospital. Our hypothesis was that there is an increased prevalence and clinical relevance of positive abdominal/pelvic CT findings in senior patients. A research ethics board-approved retrospective review of all adult patients who underwent an emergency CT of the abdomen and pelvis for acute nontraumatic abdominal and/or pelvic signs and symptoms was performed. Two thousand one hundred two patients between October 1, 2011, and September 30, 2013, were reviewed. Six hundred thirty-one patients were included in the 65 group (209 men and 253 women; mean age 77.6, age range 65-99). Overall, there were more positive CT findings for patients 65 group (257 positive cases, 55.6 %), which was a statistically significant difference (p 65 group, there were no statistically significant differences in the clinical/surgical relevance of the positive CT findings between the two groups. The findings of our retrospective study therefore refute our hypothesis that there is an increased prevalence of positive abdominal CT findings in patients >65. This may be related to ED physicians at our institution being more hesitant to order CT examinations for the younger population, presumably due to radiation concerns. However, older patients in our series were more likely to present with complicated appendicitis, and a lower threshold for ordering CT examinations of the abdomen and pelvis in this patient population should therefore be considered.

    The current dose-finding methodology for estimating the maximum tolerated dose of investigational anticancer agents is based on the cytotoxic chemotherapy paradigm. Molecularly targeted agents (MTAs) have different toxicity profiles, which may lead to more long-lasting mild or moderate toxicities as well as to late-onset and cumulative toxicities. Several approved MTAs have been poorly tolerated during long-term administration, leading to postmarketing dose optimization studies to re-evaluate the optimal treatment dose. Using data from completed bortezomib dose-finding trials, we explore its toxicity profile, optimize its dose, and examine the appropriateness of current designs for identifying an optimal dose. We classified the toxicities captured from 481 patients in 14 bortezomib dose-finding studies conducted through the National Cancer Institute Cancer Therapy Evaluation Program, computed the incidence of late-onset toxicities, and compared the incidence of dose-limiting toxicities (DLTs) among groups of patients receiving different doses of bortezomib. A total of 13,008 toxicities were captured: 46% of patients' first DLTs and 88% of dose reductions or discontinuations of treatment because of toxicity were observed after the first cycle. Moreover, for the approved dose of 1.3 mg/m(2), the estimated cumulative incidence of DLT was > 50%, and the estimated cumulative incidence of dose reduction or treatment discontinuation because of toxicity was nearly 40%. When considering the entire course of treatment, the approved bortezomib dose exceeds the conventional ceiling DLT rate of 20% to 33%. Retrospective analysis of trial data provides an opportunity for dose optimization of MTAs. Future dose-finding studies of MTAs should take into account late-onset toxicities to ensure that a tolerable dose is identified for future efficacy and comparative trials. © 2016 by American Society of Clinical Oncology.

  10. A clinical case of pseudotumorous chronic parainfectious limbic encephalitis

    Full Text Available Parainfectous limbic encephalitis (PILE associated with viruses of the Herpesviridae family is one of the forms of chronic herpes encephalitis characterized by limbic system dysfunction and a prolonged course with frequent exacerbations. There are two types of the course of the disease: latent autoimmune limbic encephalitis (LE progressing to mesial temporal sclerosis and pseudotumorous granulomatous LE. The latter (inflammatory pseudotumor or granuloma is characterized by the formation of a polymorphic inflammatory infiltrate with the elements of fibrosis, necrosis, and a granulomatous reaction and by myofibroblast cells. This is a slowly growing benign pseudotumor that contains much more plasma cells than inflammatory ones. The diagnosis of pseudotumorous LE is difficult and requires the participation of a neurologist, an immunologist, an oncologist, and a neurosurgeon. Perfusion computed tomography, magnetic resonance imaging, and magnetic resonance spectroscopy give proof to the adequacy of the term inflammatory pseudotumor because it is histologically difficult to characterize the lesion as a tumor or inflammation. When a chronic lesion in the central nervous system is lately diagnosed, the prognosis of the disease may be poor and complicated by the development of resistant symptomatic focal epilepsy and emotional, volitional, and cognitive impairments. It was differentially diagnosed from brain tumors (astrocytic, oligodendroglial, and mixed gliomas, ependymal, neuronal, neuroglial, and embryonal tumors, meningiomas, cholesteatomas, dermoid cysts, teratomas, and cysts, other reactive and inflammatory processes (leukemic infiltrations, systemic lupus erythematosus, multiple sclerosis, encephalomyelitis, hypoparathyroidism, Addison's disease, vitamin A intoxication, and the long-term use of glucocorticoids and contraceptives. The authors describe a clinical case of the pseudotumorous course of chronic PILE in a 28-year-old woman

  11. Clinical and histological findings in nephrogenic systemic fibrosis

    Cowper, Shawn E.; Rabach, Morgan; Girardi, Michael

    2008-01-01

    Nephrogenic systemic fibrosis (NSF) is a relative newcomer to the world of medicine. NSF was introduced just over 10 years ago as nephrogenic fibrosing dermopathy, but with further investigation, its systemic nature was determined. The strict adherence to a definition requiring both clinical and pathological concordance has allowed for careful separation of this entity from other fibrosing disorders, leading eventually to the realization that gadolinium-based contrast agents were closely associated with its onset. As planned prospective studies get underway, it is of paramount importance that researchers and clinicians realize that NSF remains a very challenging diagnosis, and that both clinical and histopathological criteria must be employed to reach the most accurate diagnosis possible

    To integrate neurophysiological findings with clinical and imaging data in a consecutive series of multiple sclerosis (MS) patients developing facial numbness during the course of an MS attack. Nine consecutive patients with MS and recent-onset facial numbness were studied clinically, imaged with routine MRI, and assessed neurophysiologically with trigeminal somatosensory evoked potential (TSEP), blink reflex (BR), masseter reflex (MR), facial nerve conduction, facial muscle and masseter EMG studies. All patients had unilateral facial hypoesthesia on examination and lesions in the ipsilateral pontine tegmentum on MRI. All patients had abnormal TSEPs upon stimulation of the affected side, excepting one that was tested following remission of numbness. BR was the second most sensitive neurophysiological method with 6/9 examinations exhibiting an abnormal R1 component. The MR was abnormal in 3/6 patients, always on the affected side. Facial conduction and EMG studies were normal in all patients but one. Facial numbness was always related to abnormal TSEPs. A concomitant R1 abnormality on BR allowed localization of the responsible pontine lesion, which closely corresponded with MRI findings. We conclude that neurophysiological assessment of MS patients with facial numbness is a sensitive tool, which complements MRI, and can improve lesion localization. Copyright © 2016 Elsevier B.V.

    2005-01-01

    This paper seeks to provide a review of research findings into the clinical experience from the perception of students, with the aim of improving the clinical placements of radiation therapy students. Drawing on evidence from other allied health professions, the attributes of the ideal supervisor perceived by students is presented. The effect of clinical environment, departmental culture and communication with universities on student perception is also discussed. The lack of literature on radiation therapy education in the clinical setting has been highlighted and may be remedied in the future with the appointment of research radiation therapists. There is an ongoing need for the universities to assist radiation therapists in maintaining their skills in the supervision of students, perhaps through the provision of workshops and seminars. The list of attributes of the ideal supervisor extracted from the literature is extensive. It is an unrealistic expectation for a person to possess all of the characteristics, however the challenge is for supervisors to develop and exhibit as many as possible.

    Full Text Available Objective. To describe the clinical, radiological and pathological findings in a patient with methadone-induced delayed posthypoxic encephalopathy (DPHE. Case Report. A Thirty-eight-year-old man was found unconscious for an unknown duration after methadone and diazepam ingestion. His initial vitals were temperature 104 degree Fahrenheit, heart rate 148/minute, respiratory rate 50/minute, and blood pressure 107/72 mmhg. He developed renal failure, rhabdomyolysis, and elevated liver enzymes which resolved completely in 6 days. After 2 weeks from discharge he had progressive deterioration of his cognitive, behavioral and neurological function. Brain MRI showed diffuse abnormal T2 signal in the corona radiata, centrum semiovale, and subcortical white matter throughout all lobes. Extensive work up was negative for any metabolic, infectious or autoimmune disorder. Brain biopsy showed significant axonal injury in the white matter. He was treated successfully with combination of steroids and antioxidants. Follow up at 2 year showed no residual deficits. Conclusion. Our observation suggests that patients on methadone therapy should be monitored for any neurological or psychiatric symptoms, and in suspected cases MRI brain may help to make the diagnosis of DPHE. A trial of steroids and antioxidants may be considered in these patients.

    The clinical, radiographic, arthroscopic and pathological findings of 10 horses with injury to the cranial cruciate ligament are presented. The most consistent clinical signs included moderate to severe distension of the femoropatellar joint and a Grade III to a Grade V out of V lameness. Craniocaudal instability could be elicited in five horses under general anaesthesia and in one conscious horse. Radiographic evaluation of the stifles revealed that avulsion fracture of the medial intercondylar eminence was the most common finding in six out of 10 horses. Arthroscopic examination of the affected femorotibial joints were performed in five horses. This confirmed the presumptive diagnosis of cranial cruciate ligament injury or rupture. Post mortem examinations were performed on two horses which documented partial tears of the cranial cruciate ligament

    Fifty-tree patients with localized painful spine syndrome were investigated prospectively by contrast-enhanced MRI. Pain was not predominantly radiating and there was no clinical evidence of spinal infection. In all patients, sagittal SE T1-weighted, fast-SE T2-weighted or turbo-STIR, and T1-weighted frequency-selective fat-suppressed images were obtained. We identified 37 vascularized disks in 26 patients. In 18 patients the changes had occurred spontaneously, in 6, the affected disk had been operated on previously, and 2 patients had spondylolisthesis. In 15 patients, vascularization was accompanied by medullary edema adjacent to the vertebral endplates. In one of the vascularized disks, herniation was also found. In seven patients, ventral diskectomy was performed. Histopathologic findings confirmed disk vascularization in six of seven cases. Degenerative, band-like disk vascularization is a feature which is associated with local pain. It is demonstrated by contrast-enhanced MRI. Degenerative disk vascularization is an important differential diagnosis to bacterial spondylodiskitis. It can be a cause of pain in patients with postdiskectomy syndrome. (orig./MG)

    After middle ear reconstruction using partial or total ossicular replacement prostheses (PORP/TORP), an air-bone gap (ABG) may persist because of prosthesis displacement or malposition. So far, CT of the temporal bone has played the main role in the diagnosis of reasons for postoperative insufficient ABG improvement. Recent experimental and clinical studies have evaluated flat panel CT (fpCT) as an alternative imaging technique that provides images with high isovolumetric resolution, fewer metal-induced artefacts and lower irradiation doses. One hundred and seven consecutive patients with chronic otitis media with or without cholesteatoma underwent reconstruction by PORP (n = 52) or TORP (n = 55). All subjects underwent preoperative and postoperative audiometric testing and postoperative fpCT. Statistical evaluation of all 107 patients as well as the sole sub-assembly groups (PORP or TORP) showed a highly significant correlation between hearing improvement and fpCT-determined prosthesis position. FpCT enables detailed postoperative information on patients with middle ear reconstruction. FpCT is a new imaging technique that provides immediate feedback on surgical results after reconstructive middle ear surgery. Specific parameters evaluated by fpCT may serve as a predictive tool for estimated postoperative hearing improvement. Therefore this imaging technique is suitable for postoperative quality control in reconstructive middle ear surgery. (orig.)

    Full Text Available BACKGROUND: Childhood meningitis continues to be an important cause of mortality in many countries. The search for rapid diagnosis of acute bacterial meningitis has lead to the further exploration of prognostic factors. This study was scheduled in an attempt to analyze various clinical symptoms as well as rapid laboratory results and provide an algorithm for the prediction of specific bacterial aetiology of childhood bacterial meningitis. METHODOLOGY AND PRINCIPAL FINDINGS: During the 32 year period, 2477 cases of probable bacterial meningitis (BM were collected from the Meningitis Registry (MR. Analysis was performed on a total of 1331 confirmed bacterial meningitis cases of patients aged 1 month to 14 years. Data was analysed using EPI INFO (version 3.4.3-CDC-Atlanta and SPSS (version 15.0-Chicago software. Statistically significant (p or = 15000/microL (OR 2.19 with a PPV of 77.8% (95%CI 40.0-97.2. For the diagnosis of Haemophilus influenzae, the most significant group of diagnostic criteria included, absence of haemorrhagic rash (OR 13.61, age > or = 1 year (OR 2.04, absence of headache (OR 3.01, CSF Glu < 40 mg/dL (OR 3.62 and peripheral WBC < 15,000/microL (OR 1.74 with a PPV of 58.5% (95%CI 42.1-73.7. CONCLUSIONS: The use of clinical and laboratory predictors for the assessment of the causative bacterial pathogen rather than just for predicting outcome of mortality seems to be a useful tool in the clinical management and specific treatment of BM. These findings should be further explored and studied.

    Full Text Available Background: Dermoscopy is an important tool for the diagnosis of pigmented skin lesions. Newly, this method has also been used in the diagnosis and follow-up hair and scalp disorders. Objective: The objective of this study was to investigate dermoscopic findings in a sample of patients with clinical and histopathological compatible with cicatricial alopecia. Methods: Twenty nine patients with cicatricial alopecia diagnosed by clinical and histological findings were examined by dermoscopy.. Results: Dermoscopic features evaluated included folliculitis decalvans (n=8, pseudopelade of Brocq (n=7, lichen planopilaris (n=6, discoid lupus erythematosus (n=2, dissecting cellulitis (n=1, and secondary cicatricial alopecia (n=5. Visualization of structures previously examined with naked eye were seen in great detail with dermoscopy. The loss of follicular orifices was seen in all patients with cicatricial alopecia. Perifollicular scaling, arborizing red lines, honeycomb pigment pattern, white dots and tufted hairs were the other most obvious findings. Conclusion: Use of dermoscopy in the clinical evaluation of cicatrical alopecia improves diagnostic capability beyond simple clinic inspection, but larger studies correlating dermoscopic findings with histopathology exams are needed to improve understanding of this method.

    There are 2 different kinds of chronic otitis media: Otitis media chronica mesotympanalis and otitis media chronica epitympanalis (cholesteatoma). The incidence of chronic otitis media as reported in literature differs in a wide range. The incidence rates vary between 0.45 and 46%. Both, otitis media chronica mesotympanalis and cholesteatoma, lead to eardrum perforation due to lengthy and recurring inflammations. Furthermore, chronic otitis media is characterized by frequently recurring otorrhea and conductive hearing loss. Georg Thieme Verlag KG Stuttgart · New York.

    Extracting evidence of the absence of a target of interest from medical text can be useful in clinical inferencing. The purpose of our study was to develop a natural language processing (NLP) pipelineto identify the presence of indwelling urinary catheters from electronic medical notes to aid in detection of catheter-associated urinary tract infections (CAUTI). Finding clear evidence that a patient does not have an indwelling urinary catheter is useful in making a determination regarding CAUTI. We developed a lexicon of seven core concepts to infer the absence of a urinary catheter. Of the 990,391 concepts extractedby NLP from a large corpus of 744,285 electronic medical notes from 5589 hospitalized patients, 63,516 were labeled as evidence of absence.Human review revealed three primary causes for false negatives. The lexicon and NLP pipeline were refined using this information, resulting in outputs with an acceptable false positive rate of 11%.

    Recessive X-linked ichthyosis (XLI), the second most common ichthyosis, is caused by mutations in the STS gene encoding the steroid sulfatase enzyme. A complete deletion of the STS gene is found in 85-90% of cases. Rarely, larger deletions involving contiguous genes are detected in syndromic patients. We report the clinical and molecular genetic findings in a series of 35 consecutive Italian male patients. All patients underwent molecular testing by MLPA or aCGH, followed, in case of negative results, by next generation sequencing analysis. Neuropsychiatric, ophthalmological and pediatric evaluations were also performed. Our survey showed a frequent presence of disease manifestations at birth (42.8%). Fold and palmoplantar surfaces were involved in 18 (51%) and 7 (20%) patients, respectively. Fourteen patients (42%) presented neuropsychiatric symptoms, including attention deficit hyperactivity disorder and motor disabilities. In addition, two patients with mental retardation were shown to be affected by a contiguous gene syndrome. Twenty-seven patients had a complete STS deletion, one a partial deletion and 7 carried missense mutations, two of which previously unreported. In addition, a de novo STS deletion was identified in a sporadic case. The frequent presence of palmoplantar and fold involvement in XLI should be taken into account when considering the differential diagnosis with ichthyosis vulgaris. Our findings also underline the relevance of involving the neuropsychiatrist in the multidisciplinary management of XLI. Finally, we report for the first time a de novo mutation which shows that STS deletion can also occur in oogenesis. This article is protected by copyright. All rights reserved.

    Full Text Available Central nervous system’s disorders including chronic meningitis (CM have considerable mortality and irreversible complications, and diagnosis and treatment of CM is difficult. In this retrospective study we reviwed epidemiological and clinical findings, treatment results and prognostic factors of 97 patients with CM admitted in Imam Khomeini hospital for the last 10 years. Important etiological factors in this study included: Mycobacterium Tuberculousis (8.2% Brucellae SP (5.2%, malignancies (1% and unknown (85.5%; the sexual ratio was 2:1 (Male/Female and the most common clinical manifestations were: fever, headache, cranial and motor neuron involvement, seizure and ataxia. Treatment regimens used included antituberculosis agents with or witout corticosteroids, in which the prognosis was better in patients who had been treated with antituberculosis agents alone. The mortality rate was 22.7%, which was in accordance with other studies. We suggest using of antituberculosis treatment alone in comparison with antituberculosis and corticosteroid. Last but not least a double blind randomized clinical trial for a longer period is needed to further substantiate the results of this study.

    In 1960 Van Wyk and Grumbach described a syndrome of juvenile hypothyroidism, precocious puberty and ovarian enlargement. These findings undergo complete regression with thyroid hormone replacement therapy. This diagnosis can be made on the basis of imaging findings and thyroid function analysis, avoiding surgery. To relate the distinctive clinical and imaging features and putative pathophysiological mechanism of a series of patients with Van Wyk and Grumbach syndrome (VWGS). Patients with VWGS diagnosed at two large children's hospitals over a 6-year period beginning in 1999 were retrospectively reviewed. A literature review was also conducted. Five female patients were diagnosed with cystic ovarian enlargement and hypothyroidism at ages ranging from 9 to 17 years. Isosexual precocious puberty was found in prepubescent patients. Associated findings included delayed bone age, ascites, and pleural and pericardial effusions. Ovarian cyst involution occurred following treatment of the hypothyroidism. The association of primary hypothyroidism with cystic ovarian enlargement and precocious puberty is important to recognize. In the absence of suspected ovarian torsion, surgery is unnecessary, as cyst regression occurs after appropriate thyroid hormone replacement. Noncompliance with hormone replacement therapy should be considered when cystic ovarian enlargement is noted in patients with a history of hypothyroidism. (orig.)

    Increasing numbers of conventional X-rays, computed tomography and magnetic resonance imaging in the inpatient, outpatient and scientific routine leads to an increasing number of incidental findings. The correct interpretation of these incidental findings with respect to the relevance and the evaluation concerning further work-up is an important task of radiologists. Description of common incidental findings in musculoskeletal imaging and their clinical classification. A PubMed literature search was performed using the following terms: incidental findings, population-based imaging, musculoskeletal imaging, non-ossifying fibroma, enchondroma, osteodystrophia deformans, chondrosarcoma, fibrous dysplasia, simple bone cyst, unicameral bone cyst, solitary bone cyst, aneurysmal bone cyst, vertebral hemangioma, bone island, osteopoikilosis, Tarlov cyst and diffuse idiopathic skeletal hyperostosis (DISH). Incidental findings are observed in up to 40% of imaging procedures. In up to 6% these incidental findings involve the skeletal system. Common incidental findings are discussed and their clinical relevance is explained. (orig.) [de

    The computerized tomogram (CT) of a senile case of Creutzfeldt-Jacob disease with rapid progress, showed after an initially minor parietal dilatation of the gyri, a volume increase, predominantly on the right side, in the area of the cerebral convexity and a right-preponderant dilatation of the anterior horns. By neuropathologic examination indications for a passed cerebral oedema was found, covering the cortex atrophy, which previously had been detected by CT. Progression and local intensity of the atrophic signs in CT - in combination with clinical and electroencephalographic findings - suggest the existence of a Creutzfeldt-Jakob disease and permit its delineation against other atrophying processes.

    Enrollment of children into pediatric clinical trials remains challenging. More effective strategies to improve recruitment of children into trials are needed. This study used in-depth qualitative interviews with parents who were approached to enroll their children in a clinical trial in order to gain an understanding of the barriers to pediatric clinical trial participation. Twenty-four parents whose children had been offered the opportunity to participate in a clinical trial were interviewed: 19 whose children had participated in at least 1 clinical trial and 5 who had declined participation in any trial. Each study aspect, from the initial explanation of the study to the end of the study, can affect the willingness of parents to consent to the proposed study and future studies. Establishing trust, appropriate timing, a transparent discussion of risks and benefits oriented to the layperson, and providing motivation for children to participate were key factors that impacted parents' decisions. In order for clinical trial accrual to be successful, parents' priorities and considerations must be a central focus, beginning with initial trial design. The recommendations from the parents who participated in this study can be used to support budget allocations that ensure adequate training of study staff and improved staffing on nights and weekends. Studies of parent responses in outpatient settings and additional inpatient settings will provide valuable information on the consent process from the child's and parent's perspectives. Further studies are needed to explore whether implementation of such strategies will result in improved recruitment for pediatric clinical trials.

    Full Text Available PurposeIn the pediatric population, Rathke's cleft cysts (RCCs are known to be an infrequent cause of headaches, visual disturbances, and pituitary dysfunction. We investigated the clinical characteristics of children in whom RCCs were incidentally discovered and evaluated whether RCCs influence the treatment response of patients with proven endocrinopathy.MethodsA retrospective analysis was conducted in 34 patients with RCCs who were diagnosed between 2006 and 2013 at Hallym University Medical Center. Their clinical, hormonal, and imaging findings were reviewed. We evaluated the clinical outcomes of the patients with concomitant RCCs and endocrinopathy compared to matched controls.ResultsTwenty-six of 34 patients with radiologically proven RCCs had endocrine disorders. They were 9 boys and 17 girls, with ages ranging from 4.8 to 17.4 years at the time of the diagnosis. Of these, 7 (27% had idiopathic short stature, 7 (27% had growth hormone deficiency (GHD, and 12 (46% had central precocious puberty (CPP. Nineteen of 26 patients (73.1% showed low signal intensities on T1-weighted images (T1WI and high signal intensities on T2-weighted images. The incidence of hypointensity on T1WI was higher in the patients with RCCs accompanied by endocrinopathy than in those without endocrinopathy (P=0.033. The treatment outcomes of the patients with CPP and GHD with and without RCCs were similar.ConclusionCPP and GHD patients with a small RCC (less than 20 mm expressing cystic magnetic resonance intensity can be managed with medical treatment, although the RCCs need to be closely monitored in radiological studies to observe their growth.

    To assess the high-resolution computed tomography (HRCT) findings in rheumatoid arthritis and their correlation with clinical data, respiratory function tests (RFT) and bronchoalveolar lavage (BAL). Nineteen patients were studied by inspiratory and expiratory HRCT scan and clinical examination: 17 also underwent RFT and 12 were also subjected to BAL. The χ''2 test was used to analyze the correlation among the clinical data, RAFT, BAL and the HRCT images. Six patients had no respiratory symptoms and seven were smokers. The most common findings was bronchiectasis (37%), followed by nodules (26%), ground glass (26%), non septal lines (21%), septal lines (16%), emphysema (21%), lymph nodes (21%), pleural changes (16%), pericardial changes (11%) and enlarged pulmonary artery (5%). All the patients presented a mosaic pattern on expiration. The RFT disclosed obstructive lung disease in 74% of cases, normal in 41% and restrictive disease in 12%. BAL was normal in 50% of the patients, containing a high neutrophil count in 42% and high lymphocyte count in 8%. Only the correlations between smoking and emphysema and between the results of RFT and bronchiectasis, septal and non septal lines, ground glass and honey combing were found to be statistically significant. HRCT detects pulmonary involvement in rheumatoid arthritis even in the absence of respiratory symptoms. The most common finding is bronchiectasis. Air trapping is always present in expiration, obstructive lung disease being the most common finding in RFT. The only significant associations were those between smoking and emphysema and between the results of RFT and the HRCT findings, as indicated by the high incidence of restrictive lung disease in these patients.

    Objective: To investigate the differences and the similarities of clinical presentations and CT features between type B3 thymoma (atypical thymoma) and type C thymoma (thymic carcinoma) in the WHO classification of thymic epithelial tumors. Methods: Complete CT findings of thirty cases of type B3 and seventeen cases of type C thymic epithelial tumors confirmed by histopathology according to WHO 2004 Classification System and clinical features including the prognosis of each case were reviewed retrospectively. Statistical analyses of the data for the age and the long diameter were performed with Independent-Samples t test between the two groups. Statistical analysis for gender, association with myasthenia gravis, method of the operation, contours, shapes, calcification,necrosis, enhancement pattern of the tumors on CT, presence of mediastinal lymphadenopathy, invasion of mediastinal fat, chest wall, pericardium, great vessel, pleural mediastinum, metastasis to the plural, pleural effusion, distant metastasis were performed with Fisher exact test. Kaplan-Meier method was employed for survival analysis. Results: Clinical data: the average age of type B3 group was significantly younger (t=-2.905, P=0.006). 90.0% (27/30) of patients in type B3 group were complicated by myasthenia gravis, while only 5.9% (1/17) of patients in type C group were complicated by myasthenia gravis. The difference between the two groups was statistically significant (P=0.000). The ratio of complete resection of type B3 group (80.0%) was significantly higher than that in type C group (P=0.001), 70.6% (12/17) of patients in type C group died within 2 years after surgical resection, while only 20.0% (6/30) of patients in type B3 group died within one to nine years after surgical resection. Three years' survival ratio of C group was 29.4%, and five years' survival ratio of C group was lower than 14.7%, which was significantly lower than B3 group five years' survival ratio was 94.7%), which was

    (1) To describe clinical and radiologic findings in patients with esophageal foreign bodies. (2) To examine the sensitivity and specificity of history, physical examination, and radiologic studies in children with suspected foreign body ingestion. A retrospective cohort study was performed evaluating all children who underwent esophagoscopy for suspected foreign body ingestion at our institution from 2006 to 2013. Five hundred forty-three patients were included (54% male). Average age was 4.7 years (SD = 4.1 years). Foreign bodies were identified on esophagoscopy in 497 cases (92%). Ingestion was witnessed in 23% of cases. Most common presenting symptoms were choking/gagging (49%), vomiting (47%), and dysphagia/odynophagia (42%). Most patients with foreign bodies had a normal exam (76%). Most foreign bodies were radiopaque (83%). In 59% of patients with normal chest radiographs, a foreign body was present. Sensitivity and specificity of 1 or more findings on history, physical examination, and imaging were 99% and 0%, 21% and 76%, and 83% and 100%, respectively. Most patients with esophageal foreign bodies are symptomatic. Although many patients will have a normal physical examination, an abnormal exam should increase suspicion for a foreign body. Most esophageal foreign bodies are radiopaque, but a normal chest radiograph cannot rule out a foreign body. © The Author(s) 2015.

    Since ankylosing spondylits (S.a.) tends to be milder and less progressive in women than in men, there are great difficulties in diagnosing S.a. in fermale patients. The role of scintiscanning for investigation of S.a. in women is discussed by few examiners only especially there are no investigations of quantitative sacroiliac scintigraphy in large groups of female patients. Quantitative sacroiliac scintigraphy was performed in 19 female patients with S.a. and in 30 control subjects. The sacroiliac/sacrum ratio (Index ISG/sacrum) was calculated. Significantly increased uptakes were found in the patient group compared with the controls. Especially in the early periods of S.a. the activity index was highest. When history and physical examination lead to a suspicion of S.a. and there is not verification by roentgenographic studies, sacroiliac joint scintigraphy is indicated. If clinical and laboratory findings are respected in each patient, quantitative sacroiliac scintigraphy is useful for the early diagnosis of S.a. in female patients. (orig.)

    Necrotizing pneumonia causes necrosis of pulmonary parenchyma and may lead to pulmonary gangrene. Prior to the antibiotic era, extensive pulmonary involvement was potentially fatal, but the incidence of necrotizing pneumoniais now less common. On contrast-enhanced CT scans, consolidation with contrast enhancement containing necrotic foci with low attenuation and cavities is characteristic. Radiologic findings do not differ according to the causative organism and in most of cases, specific diagnosis may be impossible. Clinical findings and certain characteristic radiologic findings may be helpful for narrowing the differential diagnosis. We illustrate the clinical and radiologic characteristics of necrotizing pneumonia according to causative bacterial organisms

    Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) is the most common genetic cause of ischemic strokes and a most important model for the study of subcortical vascular dementia. This unrelentlessly progressive disease affects many hundreds of families all over the world but is not well studied in Brazil. This manuscript reviews pathogenetic, clinical, radiological and therapeutic features of CADASIL. The causal mutations are now very well known, but the same can not be said about its intimate pathogenetic mechanisms. The variable clinical presentation should lead physicians to actively pursue the diagnosis in many settings and to more thoroughly investigate family history in first degree relatives. A rational approach to genetic testing is however needed. Treatment of CADASIL is still largely empiric. High-quality therapeutic studies involving medications and cognitive interventions are strongly needed in CADASIL. (author)

    Full Text Available Background: Thrombocytopenia is an important cause of bleeding. Different clinical conditions associated with thrombocytopenia and their reflections to the hemostatic table will be examined in this study. Methods: A total of 100 patients with thrombocytopenia who were treated in Hacettepe University between 1993 and 2013, 29 with thrombotic thrombocytopenic purpura (TTP, 36 with immune thrombocytopenic purpura (ITP, and 35 with aplastic anemia (AA, were included in the study. Clinical features and laboratory values were reviewed. Results: Thrombosis, fever, and sepsis were more frequently seen in TTP. The most common bleeding type was subcutaneous bleeding in all patient groups. Among patients with TTP, twenty-five patients (86, 2% had fever, 26 patients (89, 7% had a neurologic disorder, and 16 patients (55, 1% had renal dysfunction. Regarding the diagnostic criteria of TTP, 13 patients (44, 8% met five, 12 (41, 4% patients met four and 4 (13, 8% patients met three criteria. The median session of plasmapheresis was 17 (range; 2-127. There was no relation between session count and remission (p=0.28. Conclusion: The severity of clinical presentation and underlying disorders are the most important points with which to approach patients with thrombocytopenia. Clinical reflections may help to identify the cause of thrombocytopenia but not sufficiently demonstrative for diagnosis. [J Contemp Med 2017; 7(4.000: 316-322

    MRIs are obtained in research in healthy and clinical populations, and incidental findings have been reported. Most studies have examined adults with variability in parameters of image acquisition and clinical measures available. We conducted a prospective study of youths and documented the frequency and concomitants of incidental findings. Youths (n = 1400) with an age range from 8-23 years were imaged on the same 3T scanner, with a standard acquisition protocol providing 1.0 mm(3) isotropic resolution of anatomic scans. All scans were reviewed by an experienced board-certified neuroradiologist and were categorized into 3 groups: 1) normal: no incidental findings; 2) coincidental: incidental finding(s) were noted, further reviewed with an experienced pediatric neuroradiologist, but were of no clinical significance; 3) incidental findings that on further review were considered to have potential clinical significance and participants were referred for appropriate clinical follow-up. Overall, 148 incidental findings (10.6% of sample) were noted, and of these, 12 required clinical follow-up. Incidental findings were not related to age. However, whites had a higher incidence of pineal cysts, and males had a higher incidence of cavum septum pellucidum, which was associated with psychosis-related symptoms. Incidental findings, moderated by race and sex, occur in approximately one-tenth of participants volunteering for pediatric research, with few requiring follow-up. The incidence supports a 2-tiered approach of neuroradiologic reading and clinical input to determine the potential significance of incidental findings detected on research MR imaging scans.

    To describe the various patterns of presentation, including assisting analyses, associated with the timing of diagnosis of females with hypopituitarism and suspected clinical diagnosis of lymphocytic hypophysitis. A retrospective study of 9 consecutive females with pituitary dysfunction developed during or after pregnancy. All subjects were treated in our clinics between 2008 and 2014. Data were collected on clinical characteristics, pituitary hormone levels, and imaging findings. The study group included 9 patients with a mean age 33.7 ± 7.8 years at delivery. The probable cause of disease was lymphocytic hypophysitis. Headache or specific symptoms/signs of hypopituitarism appeared within 1 year of delivery. Five patients had headache, and 8 had difficulty breastfeeding or amenorrhea. Laboratory findings included central hypocortisolism (8/9 patients), hypogonadotropic hypogonadism (8/9), and central hypothyroidism (6/7). Insulin-like growth factor-1 (IGF-1) levels were low in 8/8 patients. Prolactin levels were low in 3/9 patients, and 1 patient had diabetes insipidus. Seven patients were diagnosed less than 1 year from symptom onset; 4 (57%) complained of headaches, and 5 (71%) had panhypopituitarism. Two patients were diagnosed later. Both had difficulty breastfeeding and amenorrhea, and one also had headaches. Both had panhypopituitarism and reduced pituitary volume. None of the patients fully recovered pituitary function. Normalization of the thyrotroph axis occurred in 3 patients, gonadotroph function in 3, the corticotroph axis in 2, and IGF-1 normalized in 1 subject. Hypopituitarism attributed to lymphocytic hypophysitis may present during pregnancy or early postpartum period with a clear clinical picture, or later, with indolent and nonspecific symptoms and signs.

    An important challenge with the application of next-generation sequencing technology is the possibility of uncovering incidental genomic findings. A paucity of evidence on personal utility for incidental findings has hindered clinical guidelines. Our objective was to estimate personal utility for complex information derived from incidental genomic findings. We used a discrete-choice experiment to evaluate participants' personal utility for the following attributes: disease penetrance, disease treatability, disease severity, carrier status and cost. Study participants were drawn from the Canadian public. We analyzed the data with a mixed logit model. In total, 1200 participants completed our questionnaire (available in English and French). Participants valued receiving information about high-penetrance disorders but expressed disutility for receiving information on low-penetrance disorders. The average willingness to pay was $445 (95% confidence interval [CI] $322-$567) to receive incidental findings in a scenario where clinicians returned information about high-penetrance, medically treatable disorders, but only 66% of participants (95% CI 63%-71%) indicated that they would choose to receive information in that scenario. On average, participants placed an important value ($725, 95% CI $600-$850) on having a choice about what type of findings they would receive, including receipt of information about high-penetrance, treatable disorders or receipt of information about high-penetrance disorders with or without available treatment. The predicted uptake of that scenario was 76% (95% CI 72%-79%). Most participants valued receiving incidental findings, but personal utility depended on the type of finding, and not all participants wanted to receive incidental results, regardless of the potential health implications. These results indicate that to maximize benefit, participant-level preferences should inform the decision about whether to return incidental findings. © 2015

    Spontaneous transmural rupture of the esophagus (Boerhaave's syndrome) is a life-threatening emergency. Prompt diagnosis is essential to a better prognosis, successful operative outcome and patient survival. The chest roentgenogram and the contrast esophagograms to follow are the most helpful diagnostic tests. The clinical manifestations are variable and may be misleading and thus delay accurate recognition. In our case report the major clinical features and radiological signs of Boerhaave's syndrome are described. The pathogenesis, characteristic clinical symptoms and the signs and radiological evaluation are reviewed. (orig.) [de

    Ischemic colitis in breast cancer patients being treated with taxane-based chemotherapy, which may lead to serious morbidities and even death, has recently been defined as a clinical entity. The purpose of this retrospective study was to evaluate the computed tomography (CT) findings in taxane-related colitis and determine their clinical relevance. CT scans of 41 patients at risk for taxane colitis were reviewed retrospectively for bowel and peritoneal abnormalities. Morphological findings were analyzed and correlated with clinical, pathological, and endoscopic findings. CT scans in 10 of the 41 patients showed a definitely abnormal colon with a thickened wall or distended with fluid, signs that are suggestive of colitis, in the context of the clinical picture. Radiographic changes in patients with taxane colitis are not specific but, in the appropriate context, can suggest the correct diagnosis and guide the patient's management

    Full Text Available Children bear a large burden of typhoid fever caused by Salmonella enterica serotype Typhi (S. Typhi in endemic areas. However, immune responses and clinical findings in children are not well defined. Here, we describe clinical and immunological characteristics of young children with S. Typhi bacteremia, and antimicrobial susceptibility patterns of isolated strains.As a marker of recent infection, we have previously characterized antibody-in-lymphocyte secretion (TPTest during acute typhoid fever in adults. We similarly assessed membrane preparation (MP IgA responses in young children at clinical presentation, and then 7-10 days and 21-28 days later. We also assessed plasma IgA, IgG and IgM responses and T cell proliferation responses to MP at these time points. We compared responses in young children (1-5 years with those seen in older children (6-17 years, adults (18-59 years, and age-matched healthy controls.We found that, compared to age-matched controls patients in all age cohorts had significantly more MP-IgA responses in lymphocyte secretion at clinical presentation, and the values fell in all groups by late convalescence. Similarly, plasma IgA responses in patients were elevated at presentation compared to controls, with acute and convalescent IgA and IgG responses being highest in adults. T cell proliferative responses increased in all age cohorts by late convalescence. Clinical characteristics were similar in all age cohorts, although younger children were more likely to present with loss of appetite, less likely to complain of headache compared to older cohorts, and adults were more likely to have ingested antibiotics. Multi-drug resistant strains were present in approximately 15% of each age cohort, and 97% strains had resistance to nalidixic acid.This study demonstrates that S. Typhi bacteremia is associated with comparable clinical courses, immunologic responses in various age cohorts, including in young children, and that TPTest

    We report the clinical and imaging findings in two elderly female patients with spontaneous rupture of the distal iliopsoas tendon from the lesser trochanter of the femur. We emphasize the key contribution of magnetic resonance (MR) imaging to this diagnosis and provide an anatomic correlation. Spontaneous rupture of the distal iliopsoas tendon should be kept in mind in the differential diagnosis of acute groin pain in the elderly. MR imaging enables positive diagnosis, by showing mass effect on the anterior aspect of the hip joint, proximal muscle thickening, and abnormal signal intensity, and by demonstrating interruption of the psoas tendon, whereas the distal insertion of the lateral portion of the iliacus muscle remains muscular and is preserved.

    AIM: The purpose of this study was to describe the clinical and high-resolution computed tomographic (HRCT) findings in patients with pulmonary tuberculosis who developed respiratory failure after starting chemotherapy. MATERIALS AND METHODS: The clinical records, chest radiographs, and HRCT findings in five patients with non-miliary pulmonary tuberculosis who developed respiratory failure after starting chemotherapy were reviewed. RESULTS: Chest radiographs taken early in the course of acute respiratory failure showed progression of the original lesions with (n = 4) or without (n = 1) new areas of opacity away from the site of the original lesions. HRCT demonstrated widespread ground-glass attenuation with a reticular pattern as well as segmental or lobar consolidation with cavitation and nodules, consistent with active tuberculous foci in all five cases. Prominent interlobular septal thickening was seen in two cases. Four of the five patients had received corticosteroids. Of these five, two died and three recovered with continued corticosteroid therapy. Transbronchial biopsy in three cases showed evidence of acute alveolar damage. CONCLUSION: In selected patients with tuberculosis who develop respiratory failure following the initiation of antituberculous therapy, HRCT may be a helpful adjunct to clinical evaluation in differentiating hypersensitivity reactions (presumed to be due to the release of mycobacterial antigens) from other pulmonary complications.

    Some nursing programmes offer night shifts for students while others do not, mainly due to the lack of evidence regarding their effectiveness on clinical learning. The principal aims of the study were to describe nursing students' perceptions and to explore conditions influencing effectiveness on learning processes during night shifts. An explanatory mixed-method study design composed of a cross-sectional study (primary method, first phase) followed by a descriptive phenomenological study design (secondary method, second phase) in 2015. Two bachelor of nursing degree programmes located in Northern Italy, three years in length and requiring night shifts for students starting in the second semester of the 1st year, were involved. First phase: all nursing students ending their last clinical placement of the academic year attended were eligible; 352 out the 370 participated. Second phase: a purposeful sample of nine students among those included in the first phase and who attended the highest amount of night shifts were interviewed. First phase: a questionnaire composed of closed and open-ended questions was adopted; data was analyzed through descriptive statistical methods. Second phase: an open-ended face-to-face audio-recorded interview was adopted and data was analyzed through content analysis. Findings from the quantitative phase, showed that students who attended night shifts reported satisfaction (44.7%) less frequently than those who attended only day shifts (55.9%). They also reported boredom (23.5%) significantly more often compared to day shift students (p=0001). Understanding of the nursing role and learning competence was significantly inferior among night shift students as compared to day shift students, while the perception of wasting time was significantly higher among night shift students compared to their counterparts. Night shift students performed nursing rounds (288; 98.2%), non-nursing tasks (247; 84.3%) and/or less often managed clinical problems

    Study Objectives: To evaluate the sleep pattern and the motor activity during sleep in a cohort of patients affected by Huntington disease (HD). Design: Cross-sectional cohort study. Setting: Sleep laboratory. Patients: Thirty HD patients, 16 women and 14 men (mean age 57.3 ± 12.2 y); 30 matched healthy controls (mean age 56.5 ± 11.8 y). Interventions: Subjective sleep evaluation: Epworth Sleepiness Scale (ESS); Berlin's Questionnaire, interview for restless legs syndrome (RLS), questionnaire for REM sleep behavior disorder (RBD). Clinical evaluation: disease duration, clinical severity (unified Huntington disease motor rating scale [UHDMRS]), genetic tests. Laboratory-based full-night attended video-polysomnography (V-PSG). Measurements and Results: The duration of the disease was 9.4 ± 4.4 y, UHMDRS score was 55.5 ± 23.4, CAG repeats were 44.3 ± 4.1. Body mass index was 21.9 ± 4.0 kg/m2. No patients or caregivers reported poor sleep quality. Two patients reported symptoms of RLS. Eight patients had an ESS score ≥ 9. Eight patients had high risk of obstructive sleep apnea. At the RBD questionnaire, two patients had a pathological score. HD patients, compared to controls, showed shorter sleep, reduced sleep efficiency index, and increased arousals and awakenings. Four patients presented with sleep disordered breathing (SDB). Periodic limb movements (PLMs) during wake and sleep were observed in all patients. No episode of RBD was observed in the V-PSG recordings, and no patients showed rapid eye movement (REM) sleep without atonia. The disease duration correlated with ESS score (P Marca G, Solito M, Calandra-Buonaura G, Provini F, Bentivoglio AR, Cortelli P.

    Aim: To describe the clinical and radiological features of focal and diffuse xanthogranulomatous pyelonephritis (XGP) in adults. Materials and methods: A retrospective review of the clinical data, laboratory findings, imaging features, and surgical treatment of 13 cases of histologically proven XGP diagnosed between January 1993 and December 2005 was undertaken. There were 10 women and three men with a mean age of 55.2 years (range 30-87 years). All patients underwent both sonography and computed tomography (CT) of the kidneys. Magnetic resonance imaging (MRI) was performed in two patients. Results: XGP was diffuse in 11 patients and focal in two patients. Fever, anorexia and weight loss, urinary symptoms, and flank pain were the most common manifestations. Urinary tract infection was found in eight patients. Sonography and CT showed diffuse kidney enlargement in seven cases and atrophy in five cases; a solitary solid mass was found in two patients. Hydronephrosis was noted in nine cases, staghorn calculus in six, and extensive pararenal disease in six. MRI failed to provide the preoperative diagnosis in the two patients with focal XGP. Total or partial nephrectomy was performed without postoperative complications. Conclusion: Although rare, XGP is the main differential diagnosis of malignant renal neoplasia. The definitive diagnosis depends on histological examination of the operative specimen. Preoperatively, the diagnosis can often be suspected based on imaging studies, primarily CT

Materials and methods: A retrospective review of the clinical data, laboratory findings, imaging features, and surgical treatment of 13 cases of histologically proven XGP diagnosed between January 1993 and December 2005 was undertaken. There were 10 women and three men with a mean age of 55.2 years (range 30-87 years). All patients underwent both sonography and computed tomography (CT) of the kidneys. Magnetic resonance imaging (MRI) was performed in two patients. Results: XGP was diffuse in 11 patients and focal in two patients. Fever, anorexia and weight loss, urinary symptoms, and flank pain were the most common manifestations. Urinary tract infection was found in eight patients. Sonography and CT showed diffuse kidney enlargement in seven cases and atrophy in five cases; a solitary solid mass was found in two patients. Hydronephrosis was noted in nine cases, staghorn calculus in six, and extensive pararenal disease in six. MRI failed to provide the preoperative diagnosis in the two patients with focal XGP. Total or partial nephrectomy was performed without postoperative complications. Conclusion: Although rare, XGP is the main differential diagnosis of malignant renal neoplasia. The definitive diagnosis depends on histological examination of the operative specimen. Preoperatively, the diagnosis can often be suspected based on imaging studies, primarily CT.

    The objective was to retrospectively determine the prevalence and patterns of iliopsoas injuries based on consecutive MRI examinations, correlated with clinical findings. From 4,862 consecutive MRI examinations of the hips and pelvis, 32 patients with 33 iliopsoas injuries were identified and graded as muscle strain, partial tendon tear, and complete tendon tears. These patients' medical records were reviewed to determine age, gender, and cause of symptoms. The prevalence of iliopsoas tendon and myotendinous injuries was 0.66% (95% CI: 0.44-0.89). There were 18 females and 14 males whose ages ranged from 7 to 95 years (mean, 54 years). The most frequent presenting symptom was hip pain and the most frequent clinical diagnosis, an occult fracture. The most common injuries in patients under 65 years (16 patients) were muscle strains and partial tendon tears, most often due to an athletic injury. The most common injury in patients 65 years and older (16 patients) was a complete tear (8 patients, all females), 2 of which were spontaneous in origin. Each grade of iliopsoas injury occurred with similar frequency. The more advanced the age of the patient, the more severe the injury. Non-athletic injuries predominated in patients 65 years and older; athletic injuries were the most common cause of iliopsoas injury in patients under 65 years. (orig.)

    In 1960 Van Wyk and Grumbach described a syndrome of juvenile hypothyroidism, precocious puberty and ovarian enlargement. These findings undergo complete regression with thyroid hormone replacement therapy. This diagnosis can be made on the basis of imaging findings and thyroid function analysis, avoiding surgery. To relate the distinctive clinical and imaging features and putative pathophysiological mechanism of a series of patients with Van Wyk and Grumbach syndrome (VWGS). Patients with VWGS diagnosed at two large children's hospitals over a 6-year period beginning in 1999 were retrospectively reviewed. A literature review was also conducted. Five female patients were diagnosed with cystic ovarian enlargement and hypothyroidism at ages ranging from 9 to 17 years. Isosexual precocious puberty was found in prepubescent patients. Associated findings included delayed bone age, ascites, and pleural and pericardial effusions. Ovarian cyst involution occurred following treatment of the hypothyroidism. The association of primary hypothyroidism with cystic ovarian enlargement and precocious puberty is important to recognize. In the absence of suspected ovarian torsion, surgery is unnecessary, as cyst regression occurs after appropriate thyroid hormone replacement. Noncompliance with hormone replacement therapy should be considered when cystic ovarian enlargement is noted in patients with a history of hypothyroidism. (orig.)

    Objective: To evaluate the clinical outcome of hyaluronan-based arthroscopic autologous chondrocyte transplantation at a minimum of 5 years of follow-up and to correlate it with the MRI evaluation parameters. Methods: Fifty consecutive patients were included in the study and evaluated clinically using the Cartilage Standard Evaluation Form as proposed by ICRS and the Tegner score. Forty lesions underwent MRI evaluation at a minimum 5-year follow-up. For the description and evaluation of the graft, we employed the MOCART-scoring system. Results: A statistically significant improvement in all clinical scores was observed at 2 and over 5 years. The total MOCART score and the signal intensity (3D-GE-FS) of the repair tissue were statistically correlated to the IKDC subjective evaluation. Larger size of the treated cartilage lesions had a negative influence on the degree of defect repair and filling, the integration to the border zone and the subchondral lamina integrity, whereas more intensive sport activity had a positive influence on the signal intensity of the repair tissue, the repair tissue surface, and the clinical outcome. Conclusion: Our findings confirm the durability of the clinical results obtained with Hyalograft C and the usefulness of MRI as a non-invasive method for the evaluation of the repaired tissue and the outcome after second-generation autologous transplantation over time.

    Full Text Available Background: Approx. 28% of patients presents to orthopedic OPD with complaints of knee pain. Common medical complications include an unstable knee, chronic knee pain, and post traumatic arthritis. Aim: To study the correlation between clinical, magnetic resonance imaging (MRI, and arthroscopic findings in knee injuries. Materials and Methods: About 30 cases with history of rotational injury having knee pain and recurrent swelling were subjected to study. Results: MRI had better sensitivity (0.95 vs. 0.85 and specificity (1.0 vs. 0.5 in comparison with clinical examination for medial meniscus. In lateral meniscus injury (sensitivity 0.65 vs. 0.61 and specificity 0.95 vs. 0.92 and in ACL injury (Sensitivity 0.77 vs. 0.8 and specificity 1.0 vs. 0.96 the sensitivity and specificity of MRI versus clinical examination showed minimal difference. Conclusion: Our conclusion is that carefully performed clinical examination can give equal or better diagnosis of meniscal and ACL injuries in comparison with MRI scan. MRI may be used as an additional tool for diagnosis.

    Current research suggests a role for biomedical knowledge in learning and retaining concepts related to medical diagnosis. However, learning may be influenced by other, non-biomedical knowledge. We explored this idea using an experimental design and examined the effects of causal knowledge on the learning, retention, and interpretation of medical information. Participants studied a handout about several respiratory disorders and how to interpret respiratory exam findings. The control group received the information in standard "textbook" format and the experimental group was presented with the same information as well as a causal explanation about how sound travels through lungs in both the normal and disease states. Comprehension and memory of the information was evaluated with a multiple-choice exam. Several questions that were not related to the causal knowledge served as control items. Questions related to the interpretation of physical exam findings served as the critical test items. The experimental group outperformed the control group on the critical test items, and our study shows that a causal explanation can improve a student's memory for interpreting clinical details. We suggest an expansion of which basic sciences are considered fundamental to medical education.
