  1. Pseudolipoma of inverted Meckel's diverticulum: clinical, radiological and pathological correlation

    International Nuclear Information System (INIS)

    Three cases of isolated inverted Meckel's diverticulum are described. In two cases an initial pathological diagnosis of small bowel lipoma was suggested. In a third case central fat was demonstrated on CT and peristalsis of the intraluminal polypoid mass was observed during US examination. In all three cases small bowel enema examination demonstrated the lesion. Correlation of the clinical, radiological and pathological features is emphasised, as this will allow the correct diagnosis.

  2. Retroperitoneal and pelvic hemangiopericytomas: A clinical, radiologic, pathologic correlative study

    International Nuclear Information System (INIS)

    The hemangiopericytoma (HP) is an aggressive neoplasm consisting of proliferation of endothelial-lined capillaries with intact reticulum sheaths surrounded by the pericyte. Approximately a fifth of these lesions occur in the retroperitoneum. This is the first large clinical, radiologic, pathologic study of retroperitoneal HP (17 cases). Significant clinical findings included a palpable mass (64%) and hypoglycemia in one. Approximately 40% were located in the true anatomic pelvis or near the cecum along the pelvic psoas muscle. Radiographically, a mass may be seen on plain film, IVP, or barium studies which might displace, compress, or rarely invade an adjacent organ. Most significant was the angiographic findings of an extremely vascular tumor with extensive collateralization, hypertrophy of vessels, and venous engorgement. On CT, HP appeared as a large, bulky well-defined enhancing tumor occasionally with areas of low density in a swirled or marbled pattern. Although by no means diagnostic, HP can be considered when a hypervascular retroperitoneal tumor is encountered on angiography or a large, enhancing mass with several low-density areas is recognized on CT

    Full Text Available Background: Olfactory groove schwannomas (OGS are rare anterior cranial fossa base tumors with only 41 cases reported in literature. Olfactory ensheathing cell schwannoma (OECS has similar clinico-radiological features as OGS, but a different cell of origin. In recent years, there is growing interest in OECS as more cases are being reported. Aims: The objective was to study the clinico-radiological features of OGS and define the histological differentiation from OECS. Materials and Methods: We retrospectively analyzed clinical, radiological, surgical and histopathological picture of all cases of OGS managed in our institute. Immuno histochemical studies were performed in these tumors for differentiating from OECS. A comprehensive review of articles published until date describing the operative treatment was done. Results: All three cases had presented with seizures, two had anosmia and papilledema. Gross-total resection was achieved in all our patients. One patient expired in the postoperative period due to septicemia. Positive expression to newer immuno histochemical biomarker CD57 (Leu7, with negative staining to smooth muscle α-actin (SMA was helpful in confirming the diagnosis of OGS and differentiating it from OECS in all our cases. Conclusions: OECS, though rare has to be differentiated from OGS using immuno histochemistry. Gross-total resection of OGS with preservation of olfactory function is often possible and curative. Although these tumors are commonly treated with microsurgical skull base approaches, an endoscopic endonasal approach can be considered in some cases, with repair using mucoperiosteal pedicled flap to prevent cerebrospinal fluid leak.

  4. Clinical and radiological observations on asbestos-related pathology

    The papers in this session, which are summarized briefly, do not cover the wide range of radiological and clinical problems resulting from inhalation of asbestos dust. Pleural effusions are found in persons exposed occupationally to asbestos, even in the absence of asbestosis, but they are difficult to attribute to such exposure. Asbestosis of the lung shows no striking symptoms and can also be diagnosed only after all other possibilities have been excluded. There are no convincing or striking morphological peculiarities that suggest that an 'asbestos lung cancer' exists. Mesotheliomas of the pleura and of the peritoneum are usually resistant to therapy of any kind, although several possibilities are discussed. Radiological surveillance is presented as being still the most effective and reliable method for medical surveillance of asbestos workers. Circumscribed pleural thickening is benign but a good indicator of exposure to mineral dusts. Diffuse pleural thickening occurs frequently in nonexposed groups and cannot, therefore, be used as an indication of exposure; however, it cannot yet be ruled out as being significant epidemiologically.

    This book is a comprehensive atlas of the clinical conditions that commonly involve the inner ear and lateral skull base. Each disorder or disease is meticulously and beautifully illustrated, with accompanying informative text. An important feature of the book is that no disorder is described from a single point of view. Instead, the clinical features are linked with both radiologic and pathologic findings to provide an all-encompassing picture of the condition in question. This is feasible because the book is the result of years of intense collaborative teamwork between departments at the University of Toronto and the Tehran University of Medical Sciences, and includes many clinical and pathologic images that could only be acquired in major referral units. It is anticipated that this atlas will assist greatly in improving collaboration between clinicians and surgeons in the diagnostic, therapeutic, and surgical management of disorders in this challenging area.

    Objectives While the majority of HPV+ oropharyngeal squamous cell carcinomas have a favorable prognosis, we search for markers of poor prognosis by carefully examining a subset of highly-aggressive cases. Study Design Seven patients with HPV+ oropharyngeal cancer who presented with non-pulmonary distant metastasis or developed distant metastasis post-treatment were identified. Eight control cases were chosen which responded well to treatment. Pathology and radiological studies were reviewed and compared. Results Two cases displayed a small cell carcinoma (SmCC) component upon pathologic review. Biomarker analysis revealed lower expression of NOTCH1 in the aggressive cohort in comparison to controls (p=0.04). Cases showed a predominance of clustering of lymph nodes, extracapsular spread and central tumor necrosis. Conclusion While most HPV-related oropharyngeal cancers display a positive prognosis, it is evident that there is a subset, which behave more aggressively. This early investigation identifies pathologic and radiologic features that may help to predict this behavior. PMID:23770280

    Background Lung nodules are being detected at an increasing rate year by year with high-resolution computed tomography (HRCT) being widely used. Ground-glass opacity nodule is one of the special types of pulmonary nodules that is confirmed to be closely associated with early stage of lung cancer. Very little is known about solitary ground-glass opacity nodules (SGGNs). In this study, we analyzed the clinical, pathological, and radiological characteristics of SGGNs on HRCT. Methods A total of 95 resected SGGNs were evaluated with HRCT scan. The clinical, pathological, and radiological characteristics of these cases were analyzed. Results Eighty-one adenocarcinoma and 14 benign nodules were observed. The nodules included 12 (15%) adenocarcinoma in situ (AIS), 14 (17%) minimally invasive adenocarcinoma (MIA), and 55 (68%) invasive adenocarcinoma (IA). No patients with recurrence till date have been identified. The positive expression rates of anaplastic lymphoma kinase and ROS-1 (proto-oncogene tyrosine-protein kinase ROS) were only 2.5% and 8.6%, respectively. The specificity and accuracy of HRCT of invasive lung adenocarcinoma were 85.2% and 87.4%. The standard uptake values of only two patients determined by 18F-FDG positron emission tomography/computed tomography (PET/CT) were above 2.5. The size, density, shape, and pleural tag of nodules were significant factors that differentiated IA from AIS and MIA. Moreover, the size, shape, margin, pleural tag, vascular cluster, bubble-like sign, and air bronchogram of nodules were significant determinants for mixed ground-glass opacity nodules (all P<0.05). Conclusion We analyzed the clinical, pathological, and radiological characteristics of SGGNs on HRCT and found that the size, density, shape, and pleural tag of SGGNs on HRCT are found to be the determinant factors of IA. In conclusion, detection of anaplastic lymphoma kinase expression and performance of PET/CT scan are not routinely recommended.

    This work describes the basic elements of pathology used in clinical practice. Pathology plays an important role in clinical and scientific work, but only a few areas of pathology will be covered. Although the contribution of oncological and surgical pathology to therapy is the most well known, the cases chosen here will involve infectious pathology, diseases of the kidney and the liver, autoimmune diseases, as well as organ transplantation. Especially important is the description of methods that enable more accurate morphological diagnoses, such as histochemistry, immunohistochemistry, immunofluorescence, and electronic microscopy. Previous experience and joint work with clinical doctors have enabled the definition of significant morphological elements as well as of essential methods of pathohistological diagnosis. Besides, as is often the case, although disease symptoms are difficult to discern and biochemical results do not show significant changes compared to normal values, the results of biopsy come as a surprise to clinical doctors. For example, in virus hepatitis B involving so-called asymptomatic HBsAg carriers, we discovered every morphological form of hepatitis, from minimal lesions to chronic, persistent, and active hepatitis. With hepatitis C, certain morphological lesions point to the etiopathogenesis of this disease and thus help to confirm the diagnosis and to instigate therapy on time. Another significant experience involves kidney biopsies in cases when clinical findings are asymptomatic. Often, in such cases, morphological findings point to glomerulonephritis and glomerulopathy at different stages. Timely and subtle morphological diagnostics offer a more precise explanation for the pathological injury of tissues than other diagnostic methods. In this way, by adopting new methods, the work of pathologists is included more and more in everyday clinical practice. The inclusion of pathologists in a transplantation team makes sure a proper selection of

    Full Text Available Context: Childhood tuberculosis is a major public health problem in developing countries with tubercular meningitis being a serious complication with high mortality and morbidity. Aim: To study the clinicopathological as well as radiological profile of childhood tuberculous meningitis (TBM cases. Settings and Design: Prospective, observational study including children <14 years of age with TBM admitted in a tertiary care hospital from Western India. Subjects and Methods: TBM was diagnosed based on predefined criteria. Glassgow coma scale (GCS and intracranial pressure (ICP was recorded. Staging was done as per British Medical Council Staging System. Mantoux test, chest X-ray, cerebrospinal fluid (CSF examination, neuroimaging, and other investigations were done to confirm TB. Statistical Analysis Used: STATA software (version 9.0 was used for data analysis. Various risk factors were determined using Chi-square tests, and a P< 0.05 was considered significant. Results: Forty-seven children were included, of which 11 (24.3% died. Fever was the most common presenting symptom, and meningismus was the most common sign. Twenty-nine (62% children presented with Stage III disease. Stage III disease, low GCS, and raised ICP were predictors of mortality. Findings on neuroimaging or CSF examination did not predict mortality. Conclusions: Childhood TBM presents with nonspecific clinical features. Stage III disease, low GCS, lack of Bacillus Calmette–Gu͹rin vaccination at birth and raised ICP seem to the most important adverse prognostic factors.

    Tumefactive demyelinating disease is a rare inflammatory demyelinating disease (IDD) of the central nervous system (CNS). The literature lacks a clear and consistent description of the clinical and radiological spectrum of this disorder, and few Chinese cases have been studied. Here we report 17 Chinese patients, with pathology confirmed CNS IDD, who had distinct clinical and imaging features from those in previous reports. Median age at onset was 47 years, with a female to male ratio of 1.1:1. Multifocal lesions were present in nine cases (53%) on their pre-biopsy magnetic resonance imagings (MRIs), with locations predominantly involving periventricular white matter (41%), subcortical white matter (41%), juxtacortical regions (41%), and cortical gray matter (35%). Moderate to severe perilesional edema and/or mass effect were present in 35% of cases. A variety of enhancement patterns were observed; most were heterogeneous, including ring-like, patchy, venular-like, nodular, punctate, and diffuse in a decreased frequency. Perilesional restriction on diffusion-weighted images (DWI) were evident in 70% cases. Clinical course prior to biopsy was a first neurological event in 82% cases. During a median follow-up of 4.1 years, 76% of cases remained as isolated demyelinating syndrome, and 70% experienced a total or near-total recovery regardless of whether they received immunotherapy. Further studies are needed, especially concerning series with pathological confirmation and long-term follow-up information.

    Our aim was to evaluate the clinical and pathological findings, mutidetector-row computed tomography (MDCT) and magnetic resonance imaging (MRI) appearances, treatment and 1-year survival of patients with HCC in non-cirrhotic liver. Histopathological and laboratory findings of 30 non-cirrhotic patients with 32 HCCs were reviewed retrospectively. MDCT and gadobenate dimeglumine-enhanced MR images were evaluated in consensus by two radiologists in terms of HCC size, presence of tumour capsule, necrosis, haemorrhage, fat and calcification, and vascular involvement. Imaging patterns were compared directly with HCC findings in a matched group of cirrhotic patients. No differences between non-cirrhotic and cirrhotic patients were noted in terms of serum α-fetoprotein levels (elevated in 11 [36.7 %] and 21 [35 %] patients, respectively). The imaging appearance at CT and contrast-enhanced MRI was typical in 27 (84.3 %) and 28 (87.5 %) cases respectively. Most lesions presented as a well-differentiated large solitary mass, with well-defined margins, areas of necrosis and peripheral capsule. No significant differences in HCC pattern were observed between cirrhotic and non-cirrhotic liver. In non-cirrhotic patients, HCC is more likely to manifest as an asymptomatic mass with elevation of serum tumour markers similar to that seen in cirrhotic patients. HCC in cirrhotic and non-cirrhotic livers show similar enhancement patterns. (orig.)

    This case report describes a 64-year-old woman with interstitial lung disease associated with clinically amyopathic dermatomyositis. Chest computed tomography revealed consolidations along bronchovascular bundles in the periphery of the lower lungs. Interstitial lung disease developed acutely, and the patient died 3 months after the clinical diagnosis. An autopsy was performed, and a large section of the lung specimen was prepared. Various interstitial lesions including organizing pneumonia, cellular and fibrotic nonspecific interstitial pneumonia, and diffuse alveolar damage were seen in the large section. Correlating the large section and computed tomography images was useful for determining the distribution of diffuse alveolar damage.

  15. Lupus mastitis - peculiar radiological and pathological features

    International Nuclear Information System (INIS)

    Lupus mastitis is a form of lupus profundus that is seen in patients with systemic lupus erythematosus. It usually presents as a swelling (or swellings) in the breasts, with or without pain. The condition is recurrent and progresses along with the underlying disease, with fat necrosis, calcification, fibrosis, scarring, and breast atrophy. Lupus mastitis is often confused with malignancy and lymphoma and, in our part of the world, with tuberculosis. Confusion is especially likely when it occurs in an unusual clinical setting. In this article, we present a case that presented with unique radiological, pathological, and clinical features. Awareness of the various manifestations of lupus mastitis is essential if unnecessary interventions such as biopsies and surgeries, and their consequences, are to be avoided

  16. Primary alveolar capillary dysplasia (acinar dysplasia) and surfactant protein B deficiency: a clinical, radiological and pathological study

    International Nuclear Information System (INIS)

    Full-term infants with severe and prolonged respiratory distress represent a diagnostic challenge. Plain radiographic findings may be nonspecific or similar to classic surfactant deficiency disease for infants with surfactant protein B deficiency and acinar dysplasia. Objectives: To describe the similar clinical-radiological patterns of two rare neonatal conditions. Six newborn babies with severe respiratory distress at birth demonstrated clinical and radiographically prolonged and progressive diffuse pulmonary opacification. All infants demonstrated hyperinflation of the lungs. The diffuse hazy opacification, which varied from mild (n=3) to moderate (n=3), progressed to severe diffuse opacification preceding death, which occurred at 12-36 days of life. Open lung biopsy confirmed the diagnosis of primary alveolar acinar dysplasia (AD) in four infants and surfactant protein B deficiency (SPBD) in two infants. In full-term babies with unexplained progressive respiratory distress from birth and progress of radiological changes, both AD and SPBD should be considered. (orig.)

    To illustrate the radiologic findings in several uncommon breast and infrequent diseases that present with unusual mammographic images. We reviewed the mammograms performed in our department between 1998 and 1995, selecting 16 patients (12 women and 4 men). Nine patients had benign breast lesions (adenomyoepithelioma, epidermal cyst, adenoid cystic carcinoma, myofibroblastoma, multiple hamartomas, intra cystic papillomas, lipoma, idiopathic granulomatous mastitis and fat necrosis) and 7 patients presented malignant breast diseases (malignant fibrous histiocytoma, intra cystic carcinoma, primary lymphoma of the breast, liposarcoma and metastasis). We present a review of the radiologic and pathologic findings in several uncommon breast diseases. (Author) 14 refs

    Recent progress in computer technology in both hardware and software, combined with marked cost reductions, have placed quantitatively accurate video densitometry systems within the reach of the individual clinician, biomedical researcher, and community hospital. While much of the attention generated by advances in image processing has focussed on larger scale procedures, such as CAT, chemical shift, and positron emission tomography, important applications can be found for considerably more modest systems. In this article, we discuss three such applications of DUMAS, a personal computer-based imaging system developed by the Image Processing Center at Drexel University. A potential technique for quantifying numbers of estrogen receptors in tumorous breast tissue samples as a predictor of patient responsiveness to hormonal therapy is described first, along with possible sources of error. The second application, also related to clinical pathology and cancer, outlines methods for relating changes in nuclear and cell morphology to the diagnosis of Sezary Cell Syndrome. The utility of binary image filtering methods in the classification of cell types is discussed. The third application involves the development of a semi-automatic procedure for the determination of vessel diameter in arteriograms. A detailed description of the optimization and curve-fitting algorithms is provided along with preliminary test results comparing various approaches. The need for user demand to fuel research and development in small-scale imaging systems is also discussed. PMID:2647281

    2011-01-01

    Full Text Available Ureteritis cystica (UC is a benign condition that commonly affects the ureter and can mimic other conditions such as transitional cell carcinoma, blood clots, air bubbles, radiolucent stones, fibroepithelial polyps, and sloughed renal papillae. Radiographically, UC is characterized by multiple small, round, lucent defects, which cause scalloping of the ureteral margins when seen in profile. The scalloping is produced by the projection of the submucosal cysts into the lumen and represents an important differential feature of this disease. We present a case of UC with a radiological pathological correlation.

    Gastrointestinal (GI) lymphoma encompasses a heterogeneous group of neoplasms that have a common lymphoid origin but variable pathologic and imaging features. Extranodal marginal zone B-cell lymphoma (ENMZL) and diffuse large B-cell lymphoma (DLBCL) are the most common. ENMZL usually occurs in the stomach, where it is associated with chronic infection by Helicobacter pylori, and is typically a superficial spreading lesion that causes mucosal nodularity or ulceration and mild wall thickening. DLBCL may arise de novo or from transformation of ENMZL or other low-grade lymphomas. This form of lymphoma produces extensive wall thickening or a bulky mass, but obstruction is uncommon. Mantle cell lymphoma is the classic cause of lymphomatous polyposis, but multiple polyps or nodules can also be seen with ENMZL and follicular lymphoma. Burkitt lymphoma is usually characterized by an ileocecal mass or wall thickening in the terminal ileum in young children, often in the setting of widespread disease. Primary GI Hodgkin lymphoma, which is rare, may be manifested by a variety of findings, though stenosis is more common than with non-Hodgkin lymphoma. Enteropathy-associated T-cell lymphoma is frequently associated with celiac disease and is characterized by wall thickening, ulceration, and even perforation of the jejunum. Accurate radiologic diagnosis of GI lymphoma requires a multifactorial approach based on the clinical findings, site of involvement, imaging findings, and associated complications. PMID:25384294

    PurposeThis study was designed to present the feasibility of an in vivo image-guided percutaneous cryoablation of the porcine vertebral body.MethodsThe institutional animal care committee approved this study. Cone-beam computed tomography (CBCT)-guided vertebral cryoablations (n = 22) were performed in eight pigs with short, 2-min, single or double-freezing protocols. Protective measures to nerves included dioxide carbon (CO{sub 2}) epidural injections and spinal canal temperature monitoring. Clinical, radiological, and pathological data with light (n = 20) or transmission electron (n = 2) microscopic analyses were evaluated after 6 days of clinical follow-up and euthanasia.ResultsCBCT/fluoroscopic-guided transpedicular vertebral body cryoprobe positioning and CO{sub 2} epidural injection were successful in all procedures. No major complications were observed in seven animals (87.5 %, n = 8). A minor complication was observed in one pig (12.5 %, n = 1). Logistic regression model analysis showed the cryoprobe-spinal canal (Cp-Sc) distance as the most efficient parameter to categorize spinal canal temperatures lower than 19 °C (p < 0.004), with a significant Pearson’s correlation test (p < 0.041) between the Cp-Sc distance and the lowest spinal canal temperatures. Ablation zones encompassed pedicles and the posterior wall of the vertebral bodies with an inflammatory rim, although no inflammatory infiltrate was depicted in the surrounding neural structures at light microscopy. Ultrastructural analyses evidenced myelin sheath disruption in some large nerve fibers, although neurological deficits were not observed.ConclusionsCBCT-guided vertebral cryoablation of the porcine spine is feasible under a combination of a short freezing protocol and protective measures to the surrounding nerves. Ultrastructural analyses may be helpful assess the early modifications of the nerve fibers.

Ablation zones encompassed pedicles and the posterior wall of the vertebral bodies with an inflammatory rim, although no inflammatory infiltrate was depicted in the surrounding neural structures at light microscopy. Ultrastructural analyses evidenced myelin sheath disruption in some large nerve fibers, although neurological deficits were not observed.ConclusionsCBCT-guided vertebral cryoablation of the porcine spine is feasible under a combination of a short freezing protocol and protective measures to the surrounding nerves. Ultrastructural analyses may be helpful assess the early modifications of the nerve fibers

    Data mining of existing radiology and pathology reports within an enterprise health system can be used for clinical decision support, research, education, as well as operational analyses. In our health system, the database of radiology and pathology reports exceeds 13 million entries combined. We are building a web-based tool to allow search and data analysis of these combined databases using freely available and open source tools. This presentation will compare performance of an open source full-text indexing tool to MySQL's full-text indexing and searching and describe implementation procedures to incorporate these capabilities into a radiology-pathology search engine.

    Meningiomas are the most common extra-axial intracranial neoplasm and frequently develop in the parasagittal region. Rarely, meningiomas may involve the middle ear and mastoid, resulting from contiguous spread of adjacent intracranial tumor, or less commonly as an isolated primary tumor of the middle ear. Patients with primary middle ear meningiomas (MEMs) often present with non-specific otologic complaints including hearing loss, otorrhea and otalgia thereby mimicking common chronic otitis media, while secondary lesions more frequently manifest sensorineural hearing loss, cranial neuropathy and other neurologic symptoms from the associated intracranial component. The radiological appearance of MEMs often overlaps with other tumors of the temporal bone. Therefore, a correct diagnosis cannot always be made prior to surgical biopsy. While gross total resection with preservation of existing neurological function is possible with smaller lesions, complete tumor removal may be extremely morbid with more extensive or adherent MEMs. In such cases, aggressive subtotal resection with close radiologic follow-up should be considered. Given the rarity of the studied condition, the literature addressing MEMs is sparse. The current study reviews ten additional cases of MEMs, highlighting the clinicopathologic and radiological features that distinguish meningiomas from other middle ear and mastoid pathology.

    Most published reviews of preclinical toxicological clinical pathology focus on the fundamental aspects of hematology, clinical chemistry, coagulation, and urinalysis in routine toxicology animal species, for example, rats, mice, dogs, and nonhuman primates. The objective of this continuing education course was to present and discuss contemporary examples of nonroutine applications of clinical pathology endpoints used in the drug development setting. Area experts discussed bone turnover markers of laboratory animal species, clinical pathology of pregnant and growing laboratory animals, clinical pathology of nonroutine laboratory animal species, and unique applications of the Siemens Advia(®) hematology analyzer. This article is a summary based on a presentation given at the 31st Annual Symposium of the Society of Toxicologic Pathology, during the Continuing Education Course titled "Nontraditional Applications of Clinical Pathology in Drug Discovery and Preclinical Toxicology."

    Full Text Available Context: As of today, there is no validated standard method to assess clinical response of breast cancer to neo- adjuvant chemotherapy (NACT. Some centers use clinical dimensions while others use radiological measurements to evaluate response according to RECIST criteria. Aims: The aim was to correlate and compare the clinical, radiological, and pathological parameters for assessing the tumor response in patients of breast cancer receiving NACT. Settings and Design: Single institution, prospective nonrandomized study conducted over a 2-year period. Materials and Methods: Patients with diagnosed breast cancer were assessed for response to NACT prior to surgery using clinical and radiological techniques. This was correlated with pathological reponse which was assessed by measuring gross dimensions and Miller-Payne grading of response to chemotherapy. Statistical Analysis Used: Spearman′s rho nonparametric. RESULTS: Fifty two patients completed the evaluation (out of 313 cases of ca breast treated during the same period with a median age of 52.5 years. We noted a 26.9% clinical complete response (CR and 19.2% had pathological CR. Clinical evaluation had a sensitivity and specificity of 73.5% and 88.5% respectively compared to 14.2% and 100% respectively for radiological assessment. Conclusions: Clinical assessment of response to NACT shows a higher sensitivity compared to radiological assessment. However the overall low sensitivity and specificity rates of clinical assessment mandate a search for a better method of evaluation.

    White matter diseases include a wide spectrum of disorders that have in common impairment of normal myelination, either by secondary destruction of previously myelinated structures (demyelinating processes) or by primary abnormalities of myelin formation (dysmyelinating processes). The pathogenesis of many white matter diseases remains poorly understood. Demyelinating disorders are the object of this review and will be further divided into autoimmune, infectious, vascular, and toxic-metabolic processes. Autoimmune processes include multiple sclerosis and related diseases: tumefactive demyelinating lesions, Balo concentric sclerosis, Marburg and Schilder variants, neuromyelitis optica (Devic disease), acute disseminated encephalomyelitis, and acute hemorrhagic leukoencephalopathy (Hurst disease). Infectious processes include Lyme disease (neuroborreliosis), progressive multifocal leukoencephalopathy, and human immunodeficiency virus (HIV) encephalopathy. Vascular processes include different types of small-vessel disease: arteriolosclerosis, cerebral amyloid angiopathy, cerebral autosomal-dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL), primary angiitis of the central nervous system, Susac syndrome, and neurolupus. Toxic-metabolic processes include osmotic myelinolysis, methotrexate leukoencephalopathy, and posterior reversible encephalopathy syndrome. The imaging spectrum can vary widely from small multifocal white matter lesions to confluent or extensive white matter involvement. Understanding the pathologic substrate is fundamental for understanding the radiologic manifestations, and a systematic approach to the radiologic findings, in correlation with clinical and laboratory data, is crucial for narrowing the differential diagnosis.

    2012-09-01

    Full Text Available Abstract Pathology and radiology form the core of cancer diagnosis, yet the workflows of both specialties remain ad hoc and occur in separate "silos," with no direct linkage between their case accessioning and/or reporting systems, even when both departments belong to the same host institution. Because both radiologists' and pathologists' data are essential to making correct diagnoses and appropriate patient management and treatment decisions, this isolation of radiology and pathology workflows can be detrimental to the quality and outcomes of patient care. These detrimental effects underscore the need for pathology and radiology workflow integration and for systems that facilitate the synthesis of all data produced by both specialties. With the enormous technological advances currently occurring in both fields, the opportunity has emerged to develop an integrated diagnostic reporting system that supports both specialties and, therefore, improves the overall quality of patient care.

    Traditionally, the radiology elective has been designed to teach medical students the fundamentals of radiologic interpretation. When questioned, many students state that they want to take a radiology elective so they can "interpret images." For the students on radiology, rotation/elective education was often passive, consisting of didactic conferences and observational shadowing of radiologists as they interpreted images. Students had only a superficial appreciation of how radiologists interacted with clinical services, multidisciplinary teams, and pathology. There was very little emphasis on imaging appropriateness or the most efficient and effective imaging for various clinical problems. With the expansion of numerous imaging modalities and the emphasis on patient-centered care, including imaging safety and dose reduction, it is important to change the focus of radiology education from interpretation to the optimal integration of imaging into clinical medicine. Radiology-pathology (rad path) electives were created at Allegheny General Hospital and the Medical University of South Carolina as a new option to provide a high-quality advanced elective for fourth-year medical students. These electives enable students to correlate radiologic images with gross and microscopic pathology specimens, thus increasing their knowledge and understanding of both. The rad path elective combines aspects of surgery, radiology, and pathology and requires students to be active learners. The implementation of this elective is an exciting work in progress that has been evolving over the past 2 and 4 years at Medical University of South Carolina and Allegheny General Hospital, respectively. We will discuss the historical basis for the elective, the advantages and challenges of having such an integrated course, and some different strategies for creating a rad path elective.

    Full Text Available Macrodystrophia lipomatosa (MDL is a rare cause of congenital macrodactyly, characterised by progressive proliferation of all mesenchymal elements, with disproportionate increase in fibro-adipose tissue. It occurs most frequently in lower limbs along the distribution of the medial plantar nerve. MDL presents as localised gigantism of the hand or foot and comes to clinical attention for cosmetic reasons, mechanical problems secondary to degenerative joint disease, or development of neurovascular compression. Here, we report a case of MDL, with altered soft tissue growth due to an earlier surgery, making clinical diagnosis difficult. However, with a complete radio-clinical work-up and review of the history, a provisional diagnosis of MDL was made, which was confirmed by histopathology and during surgery.

    2008-05-15

    Aim: To describe the radiological, endoscopic, and pathological findings of gastric schwannomas in 16 patients. Materials and methods: The radiological, endoscopic, and pathological findings of 16 surgically proven cases of gastric schwannoma were retrospectively reviewed. All patients underwent computed tomography (CT) and four patients were evaluated with upper gastrointestinal series. Two radiologists reviewed the CT and upper gastrointestinal series images by consensus with regard to tumour size, contour, margin, and growth pattern, the presence or absence of ulcer, cystic change, and the CT enhancement pattern. Endoscopy was performed in eight of these 16 patients. Six patients underwent endoscopic ultrasonography. Pathological specimens were obtained from and reviewed in all 16 patients. Immunohistochemistry was performed for c-kit, CD34, smooth muscle actin, and S-100 protein. Results: On radiographic examination, gastric schwannomas appeared as submucosal tumours with the CT features of well-demarcated, homogeneous, and uncommonly ulcerated masses. Endoscopy with endoscopic ultrasonography demonstrated homogeneous, submucosal masses contiguous with the muscularis propria in all six examined cases. On pathological examination, gastric schwannomas appeared as well-circumscribed and homogeneous tumours in the muscularis propria and consisted microscopically of interlacing bundles of spindle cells. Strong positivity for S-100 protein was demonstrated in all 16 cases on immunohistochemistry. Conclusion: Gastric schwannomas appear as submucosal tumours of the stomach and have well-demarcated and homogeneous features on CT, endoscopic ultrasonography, and gross pathology. Immunohistochemistry consistently reveals positivity for S-100 protein in the tumours.

  17. Radiologic-pathologic correlation of experimental bleomycin-induced pneumonitis

    International Nuclear Information System (INIS)

    Radiologic-pathologic correlative study of bleomycin-induced pneumonitis was performed using inflated and fixed lung specimens. Sixteen male Japanese white rabbits (body weight: 2.0-2.5 kg) were given a single intratracheal injection of 10 mg/kg bleomycin. On day 3, 10, 21, and 42 after bleomycin administration, 4 rabbits were killed, and each lung was inflated and fixed for radiologic-pathologic correlation. Early pathologic change involved a markedly exudative lesion like DAD, corresponding to the finding of markedly increased density on soft X-ray. As intraalveolar organization progressed, fibrotic changes of the alveolar septum, and atelectatic change evolved pathologically, the finding of markedly increased density developed the nature of contraction, and finally the finding of an abnormal linear shadow and air space dilatation were formed. The finding of markedly increased density and slightly increased density, respectively, did not simply correspond to the alveolar lesion and interstitial lesion pathologically. We considered that the degree of increased density depended on the degree of air content in the alveoli of the lesion. The finding of an abnormal linear shadow corresponded to the band of fibrotic tissue, and band-shaped atelectasis of alveoli. The finding of air space dilatation corresponded to the dilatation of respiratory bronchioli and alveolar ducts in the fibrotic stage, and this may show the mechanism of honeycomb lung formation. The finding of a clearly demarcated shadow with linear margins could be recognized as a lobular lesion and disappeared as fibrotic change evolved. (author)

  18. Clinical and radiological findings of myocetoma

    International Nuclear Information System (INIS)

    Objective: To investigate the clinical radiologic characteristics of mycetoma. Methods: Radiographs of 33 cases of Madura confirmed by surgery and pathology were retrospectively analyzed. Results: Of 33 cases, multiple bones were involved in 27 and single bone in 6. A total of 180 bones were destroyed including metatarsus (42), cuneiform (33), phalanges of toes (26), cuboid (11), navicula (10), talus (9), calcaneus (8), tibia (1), carpus (22), metacarpus (12), phalanges of fingers (6). X-ray changes included erosive (20) and lyric (6) destruction of bone; erosion and sclerosis (3), sclerosis (2); irregular diaphysis and cortical thickening (5), periosteal reaction (6), surrounding osteoporosis (9), joint space narrowing (7), with indistinct articular margins. Lamellar sequestrum was noted within 2 lesions. Conclusion: Mycetoma bone infection is extensive and often involves multiple bones. The main x-ray findings are erosive and lyric destruction of bone. The radiographic appearance of the Maduta foot is similar to that of chronic pyogenic osteomyelitis with some distinctions. (authors)

  19. CT Guided biopsies of musculoskeletal lesions, radiological and pathologic correlation

    International Nuclear Information System (INIS)

    Full text: The aim of the study is to overview our experiences in taking the CT guided biopsies of musculoskeletal lesions during the period of sixteen months, analysis of validity of samples taken and correlation with pathological findings. CT guided biopsies of musculoskeletal lesions were performed in 32 patients during the period of sixteen months (from December 2004 until March 2006). Age range was from 13 to 78 years. Majorities of the biopsies were performed with coaxial cutting needle system (14 G and 16 G) with introducers size 13 and 15 G. Bone biopsies were performed with Yamsidi needles in purpose of taking the bone cylinder. Majorities of the biopsies were performed under local anaesthesia except a thirteen years old child to whom CT guided biopsy of corpus Th 6 was performed under general anaesthesia. Two samples of tissues were sent in formalin solutions to Pathology Institute for pathological verification. In one case of musculoskeletal lesions CT guided biopsies didn't yield a representative tissue sample. We had high level of congruence between radiological and pathological findings; precise presented in the article. CT guided biopsies of musculoskeletal lesions are method of choice for pathologic verification of musculoskeletal lesions proving incomparable less risk compared to 'open' biopsy which requires operating theatre and general anaesthesia. Coaxial needle systems has shown as suitable for yielding representative tissue samples (two samples for each patient), and samples are also appropriate for immunohistochemical analysis

    The development of multidisciplinary team meetings (MDTMs) for radiology and pathology is a burgeoning area that increasingly impacts on work processes in both of these departments. The aim of this study was to examine work processes and quantify the time demands on radiologists and pathologists associated with MDTM practices at a large teaching hospital. The observations reported in this paper reflect a general trend affecting hospitals and our conclusions will have relevance for others implementing clinical practice guidelines.

  1. Radiologic evaluation of the maxillary natural pathologic conditions in children

    International Nuclear Information System (INIS)

    The authors evaluated the distribution of the antral pathologic conditions and their radiographic features on the Waters' radiographs of 151 children patients who had been radiographed at the department of Oral Radiology, Seoul National University Hospitals. The obtained results were as follows : 1. The most common pathologic condition was inflammatory change (58%). Percentage of cases showing cystic lesion and fibro-osseous lesion were 25% and 11% respectively. 2. In cases of inflammatory change, odontogenic origins were 12 cases (13%) and bilateral occurrences were 37 cases (39%). 3. The most common radiographic feature of the inflammatory conditions was various types of mucosal thickening (78%). Percentage of cases showing totally increased radiopacity was 18%. 4. Intrinsic cystic lesions were 26 cases (65%) and dentigerous cyst was the most common extrinsic cyst. 5. Most of the fibro-osseous lesions (15 from 17 cases) were fobrous dysplasea. 6. Maxillary sinus hypoplasia (5 cases) and Burkitt's lymphoma (4 cases) were also observed.

  2. Radiologic-pathologic correlations of small nodules in pneumoconiosis

    International Nuclear Information System (INIS)

    Radiologic-pathologic correlations were studied using an autopsied lung from a coal miner who had pneumoconiosis. The lung was inflated and fixed by Heitzman's standard method, then its serial-sliced specimens were radiographed by soft X-ray and pathologically studied. Two types of small nodular shadows were recognized in the soft X-ray image and they could also be distinguished by computed tomography. One type was considered as peribronchiolar fibrosis with dust deposits and was characterized by faint nodular shadows having the centriacinar distribution. The second type was considered as fibrotic nodules and was characterized by well-defined and dense nodular shadows having irregular distribution. It was considered useful to analyze the characteristics of small nodules by examining their distribution in the lobular structures in order to make an accurate image diagnosis of pneumoconiosis.

    Radiological and pathological correlation of the full range of benign breast lesions, with emphasis on screen-detected lesions. Detailed discussion of risk assessment. Revised and updated edition, with a new chapter on gynaecomastia. Ideal aid to the management of patients with benign or indeterminate breast lesions in a multidisciplinary setting. The second edition of this book has been extensively revised and updated. There have been numerous scientific advances in the radiology, pathology and risk assessment of benign breast lesions since the publication of the first edition. The first edition concentrated on screen-detected lesions, which has since been rectified; new symptomatic and screen-detected lesions are discussed in the second edition and include: mastitis and breast abscesses, idiopathic granulomatous mastitis, diabetic mastopathy, phyllodes tumours, gynaecomastia and pseudoangiomatous stromal hyperplasia. The chapters on columnar cell lesions and mucocele-like lesions have been extensively updated. Where applicable, genetic analysis of the benign lesions, which is becoming part of personalised medicine in the field of breast cancer, has been included. The book also presents detailed analyses of the main models, such as the Gail Model, used to assess the subsequent risk of breast cancer in individuals. The current trend in the management of all cancers is preventative. Screening mammography detects early curable cancers as well as indeterminate lesions, the latter of which are invariably pathologically benign. The author has collated important benign lesions and, based on peer-reviewed publications, has documented the relative risk of subsequent cancer to allow the patient and the clinician to implement preventative measures where possible. This book will therefore serve as an essential component of multidisciplinary management of patients with symptomatic and screen-detected benign breast lesions.

    The external ear is accessible to direct examination; the clinical history and otoscopy are sufficient to diagnose and treat most diseases of the external ear. We aim to describe the normal anatomy of the external ear, specify the indications for imaging tests, and review the clinical and radiological manifestations of the most common diseases affecting the external ear. We classify these diseases according to their origin into congenital, inflammatory, infectious, or traumatic disease or benign bone tumors or malignant tumors. Imaging does not play an important role in diseases of the external ear, but in certain clinical scenarios it can be crucial for reaching a concrete diagnosis and establishing the best treatment. Computed tomography is the first-choice technique for most diseases. Magnetic resonance imaging complements computed tomography and makes it possible to differentiate among different tissue types and to evaluate the extension of disease accurately.

    Pulmonary hyalinizing granulomata are rare, noninfectious, fibrosing lesions of the lung, which can mimic metastatic disease radiographically. Their etiology is unknown, but they may be caused by an exaggerated immune response. We report the radiology, long clinical course, and pathology of a patient with pulmonary hyalinizing granuloma who presented with initially asymptomatic pulmonary nodules. Over a 10-year period, the patient developed multiple insidious autoimmune phenomena, including lupus anticoagulant, neuromyotonia, demyelinating sensorimotor polyneuropathy, and eventually, Morvan's syndrome. Such an association has not been previously published to our knowledge. PMID:17599621

    There is a growing need for introducing objective structured clinical examination (OSCE) as a part of radiology practical examinations in India. OSCE is an established, reliable, and effective multistation test for the assessment of practical professional skills in an objective and a transparent manner. In India, it has been successfully initiated and implemented in specialties like pediatrics, ophthalmology, and otolaryngology. Each OSCE station needs to have a pre-agreed "key-list" that contains a list of objective steps prepared for uniformly assessing the tasks given to students. Broadly, OSCE stations are classified as "manned" or "unmanned" stations. These stations may include procedure or pictorial or theory stations with clinical oriented contents. This article is one of a series of measures to initiate OSCE in radiology; it analyzes the attributes of OSCE stations and outlines the steps for implementing OSCE. Furthermore, important issues like the advantages of OSCE, its limitations, a strengths, weaknesses, opportunities, and threats (SWOT) analysis, and the timing of introduction of OSCE in radiology are also covered. The OSCE format in radiology and its stations needs to be validated, certified, and finalized before its use in examinations. This will need active participation and contribution from the academic radiology fraternity and inputs from faculty members of leading teaching institutions. Many workshops/meetings need to be conducted. Indeed, these collaborative measures will effectively sensitize universities, examiners, organizers, faculty, and students across India to OSCE and help successfully usher in this new format in radiology practical examinations.

    Objective The pediatric interstitial lung disease is a group of poorly understood disease entities. This study aimed to better understand the clinical features, radiological manifestations and pathological patterns of pediatric interstitial lung disease. Method Patients with diffuse lung disease seen in the year 2009 in 7 hospitals were studied by the Pediatric Interstitial Lung Disease Cooperative Group.Nineteen patients underwent lung biopsy, 11 cases were male, 8 were female and their age ranged from 1 year and 4 months to 13 years. Respiratory tract secretions were obtained for bacterial culture, respiratory virus antigen examination, mycoplasma antibody, EB virus, cytomegalovirus, and herpes simplex viruses antibody detection were performed. The CT or HRCT of the lung and blood-gas analysis and lung biopsy were performed for all the patients. One case underwent open lung biopsy, two cases received percutaneous biopsy, and other 16 cases were experienced video-assisted thoracoscopic biopsy. Result Five cases had been excluded, for one case had fungal infection, one had abnormal pneumoangiogram, one had sclerosing hemangioma, and two had no sufficient data. The remaining 14 cases were included into the analysis. All the 14 cases had cough, 12 of them also had tachuyppoea, four cases had rales and five had clubbing. High resolution CT showed that 12 cases had ground-glass opacification, 1 had diffuse micronodular opacities, the pathological pattern of this case was pulmonary alveolar microlithiasis, and in the case of diffuse reticulonodular opacities and cysts, the pathology of the lung was NSIP. All the 14 cases had the proof of the diagnosis or the type of the pathology. Four cases were diagnosed by pathology of the lung, incuding 1 case of pulmonary alveolar microlithiasis, 2 cases of pulmonary alveolar proteinosis, 1 case of lipoid pneumonia.Clinical-radiologic-pathologic (C-R-P) diagnosis of the other 10 cases were as follows: 4 cases had secondary

  17. Clinical or radiological diagnosis of impingement

    International Nuclear Information System (INIS)

    Shoulder impingement syndrome is a clinically common entity involving trapping of tendons or bursa with typical clinical findings. Important radiological procedures are ultrasound, magnetic resonance imaging (MRI) and MR arthrography. Projection radiography and computed tomography (CT) are ideal to identify bony changes and CT arthrography also serves as an alternative method in cases of contraindications for MRI. These modalities support the clinically suspected diagnosis of impingement syndrome and may identify its cause in primary diagnosis. In addition, effects of impingement are determined by imaging. Therapy decisions are based on a synopsis of radiological and clinical findings. The sensitivity and specificity of these imaging modalities with regard to the diagnostics of a clinically evident impingement syndrome are given in this review article. Orthopedic and trauma surgeons express the suspicion of an impingement syndrome based on patient history and physical examination and radiologists confirm structural changes and damage of intra-articular structures using dedicated imaging techniques.

    Objective: To study the clinical characteristics and radiological features of synovial sarcoma in childhood and its relation to the diagnosis and treatment. Methods:The clinical radiological features of 15 children with synovial sarcoma proved surgically and pathologically were analyzed. Results: In children, the tumor boundaries are poorly defined due to paucity of fat, and metastasis usually occurs early. Eight patients in this series had bone involvement, including: direct erosion by tumor causing cortical destruction, indirect pressure defect with sharp margin and reactive bone sclerosis and bone destruction of the primary intraosseous synovial sarcoma.Conclusion: The tumor is often misdiagnosed, the final confirmed diagnosis must be made by histological examination with imaging findings. It is emphasized that the patients should be treated with radiotherapy and chemotherapy preoperatively and postoperatively.

    This study was performed to understand the bacteriologic contamination level of radiological equipment which have frequent contacts with patients in the Department of Radiology of an university hospital in Busan area. Before sterilizing in-patient of the radiology rooms, MRSA, VRE, acinetobacter baumannii, candida albicans, and enterococcus sp. were detected. After sterilization, all the bacteria were not found. As examine times become longer, more bacteria were detected and after 7 hours, bacillus sp.(GPR), CNS, acinetobacter baumannii, and Enterococcus sp. were detected. After examining infected patients, bacillus sp.(GPR), VRE, enterococcus sp. CNS, and micrococcus sp. were detected and on the hands of radiological technologists, CNS, enterococcus sp. escherichia coli, and enterobacter sp. were detected. Similar species of bacteria were detected from each radiology room, but pseudomonas aeruginosa was detected on the handles of portable radiological equipment and the chair in the waiting room. Therefore, it is the most important to regularly sterilize radiological equipment and devices which have frequent contacts with patients and to sterilize them right after the use of infected patients in order to prevent the spread of infection. Also, thorough hand washing, education on infection and management for the characteristics of Department of Radiology should be performed for the systematic prevention of infection.

  5. Radiation pneumonitis - clinical-radiological correlation

    International Nuclear Information System (INIS)

    Post-irradiation pulmonary fibrosis is very common in patients submitted to breast, pulmonary or mediastinum neoplasia treatment. this disease has two evolutive stages: in an acute phase it is seen a density increase generally restricted to the irradiated area, with dense strias and pleural reaction; eventually, signs of volumetric reduction on the irradiated side, bronchiecstasy and pleural thickness appear. The authors present a case report of a 49-year-old male patient submitted to radiotherapy treatment with 5,000 rads, post-resection of a bronchogenic carcinoma. He developed dysphagia, dry cough and dyspnoea to even little efforts. The post-radiotherapy radiologic examinations showed mediastinal enlargement and pleural reaction. A CT scan of the chest showed bilateral and symmetric paramediastinal opacity with spiky outline and dilated and distorted bronchial tubes. Physiopathologic, clinical and radiologic aspects of this affection are discussed. (author)

    Full Text Available Studies focused on the pathological-radiological correlation of human Mycoplasma (M pneumoniae pneumonia have rarely been reported. Therefore, we extensively reviewed the literature regarding pathological and radiological studies of Mycoplasma pneumonia, and compared findings between open lung biopsy specimen and computed tomography (CT. Major three correlations were summarized. 1 Peribronchial and perivascular cuffing characterized by mononuclear cells infiltration was correlated with bronchovascular bundles thickening on CT, which was the most common finding of this pneumonia. 2 Cellular bronchitis in the small airways accompanied with exudates or granulation tissue in the lumen revealed as centrilobular nodules on CT. 3 Neutrophils and exudates in the alveolar lumen radiologically demonstrated as air-apace consolidation or ground-glass opacities. In M.pulmonis-infected mice model, pathologic patterns are strikingly different according to host cell-mediated immunity (CMI levels; treatment with interleukin-2 lead to marked cellular bronchitis in the small airways and treatment with prednisolone or cyclosporin-A lead to neutrophils and exudates in the alveolar lumen. Patients with centrilobular nodules predominant radiologic pattern have a high level of CMI, measuring by tuberculin skin test. From these findings, up-regulation of host CMI could change radiological pattern to centrilobular nodules predominant, on the other hand down-regulation of host CMI would change radiological pattern to ground-glass opacity and consolidation. It was suggested the pathological features of M. pneumoniae pneumonia may be altered by the level of host CMI.

    This atlas correlates gross neuroanatomic specimens with radiographs and computed tomographic scans. Pathologic specimens and radiographs are displayed in a similar manner. The first chapter, on embryology, shows the development of the telencephalon, diencephalon, mesencephalon, and metencephalon through a series of overlays. The anatomical section shows the surface of the brain, the ventricles and their adjacent structures, and the vascular system. CT anatomy is demonstrated by correlating CT scans with pathologic brain specimens cut in the axial plane. Pathologic changes associated with congenital malformations, injections, injuries, tumors, and other causes are demonstrated in the last six chapters

  8. Clinical and radiological diagnosis of chronic pneumonia in pneumoconiosis and dust bronchitis

    International Nuclear Information System (INIS)

    Clinical and radiologic symptomatology of chronic pneumonia is described for pneumoconiosis and chronic dust bronchitis. Combined X-ray methods of examination permit the physicians to discover this complication in dust diseases of the lungs in the presence of diffuse pneumosclerotic changes in 76.5+-3 % of cases. These data approach the values of chronic pneumonia incidence among the population. Chronic pneumonia diagnosis should be complex. If no less than 2 to 3 X-ray signs of the disease have been found simultaneously, the significance of radiologic diagnosis of chronic pneumonia in dust pathology of the lungs, rises. Radiologic examination, supported by clinical, anamnestic and laboratory data, allows one to differentiate chronic pneumonia from coniotuberculosis. Chest X-rays in dust pathology of the lungs, complicated by chronic pneumonia, should be carried out with regard to clinical indications

    Full Text Available Objective: This study was conducted to formulate location-wise radiologic diagnostic algorithms and assess their concordance with the final histopathological diagnosis so as to evaluate their utility in a rural setting where only basic facilities are available. Materials and Methods: A retrospective analysis to assess the concordance of radiology (primarily MRI with final histopathology report was done. Based on the most common incidence of tumor location and basic radiology findings, diagnostic algorithms were prepared. Results: For supratentorial intraaxial parenchymal location concordance was seen in all high-grade astrocytomas, low- and high-grade oligodendrogliomas, metastatic tumors, primitive neuroectodermal tumors, high-grade ependymomas, neuronal and mixed neuro-glial tumors and tumors of hematopoietic system. Lowest concordance was seen in low-grade astrocytomas. In the supratentorial intraaxial ventricular location, agreement was observed in choroid plexus tumors, ependymomas, low-grade astrocytomas and meningiomas; in the supratentorial extraaxial location, except for the lack of concordance in the only case of metastatic tumor, concordance was observed in meningeal tumors, tumors of the sellar region, tumors of cranial and paraspinal nerves; the infratentorial intraaxial parenchymal location showed agreement in low- as well as high-grade astrocytomas, metastatic tumors, high-grade ependymoma, embryonal tumors and hematopoietic tumors; in the infratentorial intraaxial ventricular location, except for the lack of concordance in one case of low-grade astrocytoma and two cases of medulloblastomas, agreement was observed in low- and high-grade ependymoma; infratentorial extraaxial tumors showed complete agreement in all tumors of cranial and paraspinal nerves, meningiomas, and hematopoietic tumors. Conclusion: A location-based approach to central nervous system (CNS tumors is helpful in establishing an appropriate differential diagnosis.

    Both technological advances and economic drivers have led to major changes in clinical laboratories across the world, with vastly improved testing productivity. However, the production process capability advances have far outpaced the clinical pathologists' success in assuring optimal test utilization and interpretation. While productivity of 'commodity' testing increases, our healthcare value productivity decreases. Such developments constitute a serious threat to our clinical pathology specialty, not only because pathologists may lose direct control of the commodity testing production activities, but also because the present evolution exposes a failure of our core clinical activities, the pathologist's knowledge processes that translate 'commodity' results into medical outcomes optimization. At a time when a revolution in health care organization is inescapable in the years ahead, clinical pathology must proceed from a merely reactive strategy (to fulfill the 'more with less' demands) to a proactive strategy where we build excellence and visibility in knowledge services on a strong foothold of operational excellence. Based on a Strengths-Weaknesses-Opportunities-Threats analysis, we argue that clinical pathology should safeguard and expand its healthcare value productivity by assuming leadership in building integrated laboratory services networks. We also suggest that the core knowledge processes deserve a system approach, for example, by applying a risk-based quality management system. PMID:20491600

    Objective To evaluate the clinical and pathological features of Riedel's thyroiditis (RT), and current diagnostic and treatment methods for that disease.Methods Five RT cases identified by surgery and pathological examinations at Peking Union Medi-cal College Hospital from 1985 to 2009 were analyzed and compared with the cases reported in the litera-ture in terms of clinical and pathological features. Immunohistochemical staining of kappa and lambda light chains was carried out for RT tissues from all the five patients.Results All the five cases were females, aged 45-55 years. Elevation of serum thyroid autoantibodies was found in only one patient, who had longer disease duration than the others. Pathological examination re-vealed invasive fibrosclerosis of the thyroid follicles, thyroid capsule, and the surrounding tissues. In RT tis-sues, the number of cells containing lambda chains was a little higher than those containing kappa chains.Conclusions RT is a rare disease which might be more common in middle-aged females than in other populations. Pathological features include the destruction of thyroid follicle, extension into surround-ing tissues by inflammatory cells and fibrous tissues. Immunohistochemical staining of kappa and lambda chains could help diagnose RT.

Radiological patterns of the upper lung were considered as mostly emphysema, but pathological observation revealed significant interstitial fibrosis of usual interstitial pneumonia as a major pathology. The patient eventually developed acute exacerbation of background interstitial pneumonia. Careful radiological and pathological correlation of the current case indicates that regions with distal acinar emphysema on computed tomography image may possess histologically marked dense fibrosis of lethal interstitial pneumonia.

    Lipoid pneumonia results from the pulmonary accumulation of endogenous or exogenous lipids. Host tissue reactions to the inhaled substances differ according to their chemical characteristics. Symptoms can vary significantly among individuals, ranging from asymptomatic to severe, life-threatening disease. Acute, sometimes fatal, cases can occur, but the disease is usually indolent. Possible complications include superinfection by nontuberculous mycobacteria, pulmonary fibrosis, respiratory insufficiency, cor pulmonale, and hypercalcemia. The radiological findings are nonspecific, and the disease presents with variable patterns and distribution. For this reason, lipoid pneumonia may mimic many other diseases. The diagnosis of exogenous lipoid pneumonia is based on a history of exposure to oil, characteristic radiological findings, and the presence of lipid-laden macrophages on sputum or BAL analysis. High-resolution computed tomography (HRCT) is the best imaging modality for the diagnosis of lipoid pneumonia. The most characteristic CT finding in LP is the presence of negative attenuation values within areas of consolidation. There are currently no studies in the literature that define the best therapeutic option. However, there is a consensus that the key measure is identifying and discontinuing exposure to the offending agent. Treatment in patients without clinical symptoms remains controversial, but in patients with diffuse pulmonary damage, aggressive therapies have been reported. They include whole lung lavage, systemic corticosteroids, and thoracoscopy with surgical debridement. PMID:21185165

    Astroblastoma is a very rare primary glial tumor occurring in children and young adults that is almost exclusively supratentorial in location. We report an extremely unusual presentation of a densely calcified posterior fossa astroblastoma with disseminated spinal and supratentorial metastasis. The mass exhibited neoplastic bone formation, which has not been reported, although calcifications are commonly seen in astroblastomas. A companion case of a low-grade astroblastoma that demonstrated classic histologic features but nonspecific and atypical imaging findings is also included. These cases expand the imaging and pathologic spectrum of this controversial tumor that shows highly variable biologic behavior and is difficult to distinguish from ependymoma. (orig.)

  17. Frontotemporal dementia; clinical-radiological study

    International Nuclear Information System (INIS)

    Frontotemporal dementia is the third most common degenerative condition (after Alzheimer Disease and Lewy Body Disease) of the brain. It occurs predominantly after the age of 40 and usually before the age of 65, with equal incidence in men and women. Unspecific behavioral symptoms often lead to misdiagnosis and FTD remains undetected. As in other degenerative dementias, there is no specific tissue marker; therefore, the diagnosis is established in vivo on the basis of clinical and radiological examinations. Structural and functional neuroimaging modalities are most useful in detection and differentiation of FTD as the findings are specific enough to be considered as criteria, based on which the diagnosis of this disorder can be established.

    Postpartum hemorrhage (PPH) is a potentially life threatening condition, and it remains the leading cause of maternal morbidity. Uterine atony, lower genital tract lacerations, uterine rupture or inversion, retained products of conception and underlying coagulopathy are some of the common causes of PPH. Most conditions can be diagnosed based on clinical and laboratory evaluation supplemented by ultrasound information. Computed tomography (CT) or magnetic resonance (MR) imaging can provide information for the detection, localization and characterization of PPH in some difficult cases. CT can accurately demonstrate the anatomic location of significant arterial hemorrhage as sites of intravenous contrast material extravasation, which can be as a guide for angiographic intervention. The presence of focal or diffuse intravenous contrast extravasation or a hematoma within the enlarged postpartum uterine cavity on CT can help the diagnosis of uterine atony when the clinical diagnosis of uterine atony is unclear. CT can also provide the information of other alternative conditions such as a puerperal genital hematoma, uterine rupture and concealed hematoma in other sites. MR imaging may be considered as a valuable complement to ultrasound where the ultrasound findings are inconclusive in the diagnosis and differential diagnosis of retained products of conception. Knowledge of the various radiologic appearances of PPH and the correlation with clinical information can ensure correct diagnosis and appropriate and prompt treatment planning in the patients with PPH.

  20. Lipoid pneumonia in infants: A radiological-pathological study

    International Nuclear Information System (INIS)

    A series of nine infants, 2-8 months of age, with a history of animal or vegetable fat intake within 10 days after birth, is presented. The infants developed respiratory problems and failure to thrive. Plain films and computed tomography showed areas of consolidation in the medial-posterior parts of the lungs. The areas of consolidation showed three types of changes of computed tomography. Attenuation measurements did not reveal fat. To establish the diagnosis, fine needle aspiration biopsy, tru-cut biopsy and/or open lung biopsy was done in eight infants and bronchopulmonary lavage in one patient. The pathological findings were an intense lymphocytic infiltration with scattered granulomas which contained lipid deposit. (orig.)

    The aim of this study was to identify clinical predictive factors for tumor response after preoperative chemoradiotherapy (CRT) in rectal cancer. The study involved 51 patients who underwent preoperative CRT followed by surgery between January 2005 and February 2012. Radiotherapy was delivered to the whole pelvis at a dose of 45 Gy in 25 fractions, followed by a boost of 5.4 Gy in 3 fractions to the primary tumor with 5 fractions per week. Three different chemotherapy regimens were used. Tumor responses to preoperative CRT were assessed in terms of tumor downstaging and pathologic complete response (ypCR). Statistical analyses were performed to identify clinical factors associated with pathologic tumor response. Tumor downstaging was observed in 28 patients (54.9%), whereas ypCR was observed in 6 patients (11.8%). Multivariate analysis found that predictors of downstaging was pretreatment relative lymphocyte count (p = 0.023) and that none of clinical factors was significantly associated with ypCR. Pretreatment relative lymphocyte count (%) has a significant impact on the pathologic tumor response (tumor downstaging) after preoperative CRT for locally advanced rectal cancer. Enhancement of lymphocyte-mediated immune reactions may improve the effect of preoperative CRT for rectal cancer.

    The author has clinically and radiologically investigated 57 cases of odontogenic keratocyst in 47 patients consisted of 26 males and 21 females aged from 2 to 63 years, who were pathologically diagnosed as odontogenic keratocyst at infirmaries of dental colleges, Yonsei University and Seoul national university during 1965-1986. The results were as follows: 1. The peak incidence of the disease was on their teenagers (29.8%). The ratio of Male/Female was 1.23 : 1 and incidence rate of males showed higher than their counterpart. 2. The most frequent complains were swelling in (65.9%) followed by pus discharge, unknown mass, pain, residual root. 3. The most common site was mandibular third molar and mandibular ramus region (15.8%) followed by mandibular body and ramus, mandibular third molar, mandibular anterior teeth. Incidence of this disease in mandibule was higher than in maxilla. 4. The lesions not associated with adjacent teeth were (14.0%) and in the lesions associated with adjacent teeth (31.5%) showed root resorption, (50.9%) were without root resorption, (35.1%) showed tooth migration and (50.9%) were without tooth migration. 5. The border types of the lesions were scalloped type in (52.6%), smooth type in (47.4%) and morphological type were unilocular in (50.9%), multilocular in (49.1%). 6. The radiologic cyst type of the lesions were follicular type (42.1%) followed by primordial, unclassified odontogenic, residual, lateral periodontal, median mandibular, globulomaxillary type.

    Full Text Available Hibernomas, especially located in the mediastinum, are extremely rare benign tumors, which are important to consider in the differential diagnosis of a heterogeneously enhancing mass with areas of fat attenuation on imaging of an often incidentally discovered mass. Other common possibilities in the differential include malignant tumors, such as liposarcoma, hence histopathology is usually required to confirm the diagnosis. Hibernomas often follow the distribution of sites of persistence of brown fat in adults, and intrathoracic locations are unusual. We present a very rare case of a mediastinal hibernoma in a 53-year-old woman. She presented to the emergency department with severe, progressive right neck and shoulder pain with radiation down her arm and was found to have a right apical posterior mediastinal mass on imaging. Initial radiographs of the shoulder showed a soft tissue mass within the apical right hemithorax. Further imaging with CT revealed a well circumscribed, heterogeneously enhancing mass with areas of fat attenuation. Pathology confirmed the diagnosis of mediastinal hibernoma, and the mass was completely excised. Fourteen months after surgery, the patient had a normal chest radiograph, and thirty-two months after surgery, she remains asymptomatic.

  5. Smoking-related interstitial lung diseases: radiologic-pathologic correlation

    International Nuclear Information System (INIS)

    Smoking-related interstitial lung diseases (SRILD) are a heterogeneous group of entities of unknown cause. These diseases include desquamative interstitial pneumonia (DIP), respiratory-bronchiolitis-related interstitial lung disease (RB-ILD), pulmonary Langerhans' cell histiocytosis (LCH) and idiopathic pulmonary fibrosis (IPF). High-resolution CT is highly sensitive in the detection of abnormalities in the lung parenchyma and airways. Ground-glass attenuation can occur in DIP and RB-ILD. Whereas DIP is histologically characterized by intra-alveolar pigmented macrophages, RB-ILD shows alveolar macrophages in a patchy peribronchiolar distribution. LCH shows nodular infiltrates on histopathological examination containing varying amounts of characteristic Langerhans' histiocytes. The HRCT findings are characteristically bilateral, symmetrical and diffuse, involving the upper lobe zones with sparing of the costophrenic angles. The most prominent CT features are nodules (sometimes cavitary) measuring 1 to 10 mm in diameter, cysts and areas of ground-glass attenuation. Pathologically, IPF is characterized by its heterogeneity with areas of normal clung, alveolitis and end-stage fibrosis shown in the same biopsy specimen. High-resolution CT findings consist of honeycombing, traction bronchiectasis and intralobular interstitial thickening with subpleural and lower lung predominance. Since coexisting lesions in the same cases have been observed, a better understanding of the different smoking-related interstitial lung diseases (SRILD) allows a more confident and specific diagnosis.

    We report a 21-month-old boy with multiple contiguous thoracic vertebral compression fractures involving eight vertebral bodies, attributable to non-accidental injury. No subluxation was associated, however, there was extensive injury to the upper cervical and lower lumbar regions of the spinal cord. Anterosuperior beaking, thought to represent a previous injury, was evident in a mid-lumbar vertebra. Clinical examination revealed bilateral retinal hemorrhages and retinoschisis. Death occurred as a result of severe brain edema with bilateral subdural and subarachnoid hemorrhages. Radiological-pathological correlation is presented. (orig.)

    To evaluate the clinical presentations, radiological characteristics, and natural history of healthy adolescents presenting with idiopathic spontaneous pneumomediastinum. We retrospectively reviewed the simple radiographs of 14 consecutive patients (11 males) with spontaneous pneumomediastinum, who were examined over a period of 8 years, and analyzed their clinical history, radiographic findings including distribution, combined subcutaneous emphysema, mediastinal widening, pneumothorax, pleural effusion, and resolving period on follow up chest radiographs. We also obtained CT images of 7 patients for the assessment of additional information. The most common complaint at the time of presentation was chest pain and chest discomfort (8/14), followed by neck discomfort (6/14). The chest radiograph was of diagnostic value in alI cases. The main distribution of the pneumomediastinum was cervical (14/14), upper lung (13/14) and lower lung (6/14). Combined subcutaneous emphysema was observed in 6 patients. However, there were no cases of mediastinal widening, pneumothorax or pleural effusion. Complete resolution of the pneumomediastinum on the radiograph was observed after 10 days (mean 5.6), following purely conservative treatment. There was no additional information on the CT images, as compared with that on the radiographs. Idiopathic spontaneous pneumomediastinum is a benign entity that usually goes undiagnosed, but which responds very weIl to conservative treatment.

    A clinical and radiological study was done on 96 cases of spontaneous pneumothorax, encountered in the Dept. of Radiology, Busan National University Hospital during last 3 years from March 1979 to March 1982. The result were summarized as follows: 1. In the age distribution, the ages between 20 and 39 years were most highest, as 54 cases (56.3%). In the sex distribution, the ratio of male to female was 5 : 1 in male predominance. 2. The underlying pathology of the total 96 cases of spontaneous pneumothorax were of tuberculous origin in 33.3 % and non-tuberculous origin in 66.7%. And below 20 years, most were of non- tuberculous origin. 3. In the cases of lung collapse over 2/3, non-tuberculous origin was more than tuberculous origin and had characteristics of significant mediastinal shifting, in contrast to lower percentage of fluid level by chest radiography. 4. The rupture of biebs or bullae was the main immediate causes of spontaneous pneumothorax, independent of the underlying pathology. 5. In only 27 cases (28.1%) among total 96 cases, bullae or biebs could be detected on the chest radiography. 6. In treatment of spontaneous pneumothorax, the closed thoracotomy with under water seal drainage is accepted to be the general method of treatment. But open thoracotomy is considered as the best useful therapeutic procedure to prevent the recurrence, whenever bullae or blebs are found on the chest radiography. 7. In the cases of closed thoracotomy, the recurrent rate was 25.0% and most cases were found at the ipsilateral side of the first attack. 8. Within a week, the collapsed lung were well expanded in most cases of total 96 cases, after closed thoracotomy.

    Synchronous multiple primary lung cancer is uncommon. They present at the same time, but are distinct and have different histologic features. Synchronous triple primary lung cancer is rare and only few cases have been reported previously. We described a case of synchronous triple primary lung cancers in an asymptomatic 64-year-old man that showed different radiologic features of lung tumors on chest computed tomography images. Anatomical resection and histological analysis revealed 3 different types of lung carcinoma with radiologic-pathologic correlation.

    Full Text Available Background and Objectives: Several large-scale studies on adolescent mental health have used questionnaire items derived from DSM-IV criteria to assess eating disorders. The aim of the present brief report was to analyse the capacity of self-reported eating disorder symptoms to capture clinically significant eating disorders. Methods: All pupils in the ninth grade (N = 606, response rate 98.2%, mean age = 15.4 of comprehensive school in a defined area were invited to participate in the study. Adolescents who reported some form of eating pathology (n = 126 were invited to an interview (RAB. Results: Anorexia based on the self-report resulted in a positive predictive value of 60.0% for lifetime and 20% for current eating disorder, when compared to the results in the RAB. No case of BN was detected by the RAB, but self-reported BN symptoms were predictive of both EDNOS and subclinical eating pathology. Conclusions: Self-reported eating disorder symptoms seem to be relatively good predictors of broadly defined eating pathology, but may result in overestimation of clinical conditions.

  14. Bronchial carcinoid tumors: clinical and radiological findings in 21 patients

    International Nuclear Information System (INIS)

    Bronchial carcinoid tumors are neoplasms that range from typical carcinoid s to the more aggressive atypical ones with similar imaging features. Considering the low prevalence of the tumor, we reviewed 21 patients. Patients and methods: in this retrospective observational study, we reviewed the clinical, pathological and imaging findings in 21 patients diagnosed with bronchial carcinoid tumors who were admitted to National Research Institute of Tuberculosis and Lung Disease in a 6 years period. Plain radiography and CT scan of patients were reviewed. Results: 52.4% of the patients were male and 47.6 % female. The mean age of patients was 39.1 years. The most frequent clinical symptoms were cough (n=15; 71.4%), hemoptysis (n.13; 61.9%). dyspnea (n=12; 57.1%). and pleuritic chest pain (n.7; 19%). Most of the lesions (68%) were in the right lung, 24% in the left lung. 8% in the trachea, and 19% were bilateral. Right upper lobe and right intermediate bronchus (24% and 32% respectively) were the most frequent sites of tumor. In radiologic examination, two cases (9.5%) had normal CXRs. Pulmonary collapse (52.4%) and mass (23.8%) were the most frequent findings. Reviewing CT scans showed endobronchial lesion in three (15%) and mass in 11 (55%) patients. The mass was well defined in 8 cases (72%) and ill-defined in 3 (28%). Other findings were: mediastinal invasion (45%), atelectasis (55%). post obstructive pneumonitis (2 0%) and eccentric calcification (15%). Pathological examination revealed typical (n=18: 86% ) and atypical (n.3: 14%) carcinoid tumors. Conclusion: although rare, bronchial carcinoid tumors should be considered a differential diagnosis in adult patients with cough, hemoptysis, dyspnea, and pleuritic chest pain. Chest xray and CT scan can help with diagnosis. Major imaging findings are central, round or ovoid well-defined mass, and obstruction signs like at electasis. Diagnosis and classification should be confirmed by pathological examination on sample

    Eosinophilic esophagitis is increasingly recognized as a cause of dysphagia or food impaction in pediatric patients. It has a high male predominance and is often associated with a history of allergy or asthma. To correlate fluoroscopic findings in eosinophilic esophagitis with the endoscopic and histologic findings. We retrospectively reviewed the upper gastrointestinal (UGI) findings of eosinophilic esophagitis and correlated them with the clinical, endoscopic and histologic findings in a series of 17 children (12 boys, 5 girls). UGI findings were normal in 12 children, including 4 who had a normal UGI exam after endoscopic disimpaction for an obstructing food bolus. Five children had strictures identified on UGI: one was demonstrated with endoscopy. This suggests that the impactions and strictures were due to an esophageal dysmotility rather than a fixed anatomic abnormality. Because the UGI findings are frequently normal in eosinophilic esophagitis, radiologists need to have a high index of suspicion for this disease. In children with a strong clinical history, especially impaction in the absence of an esophageal stricture, endoscopy and biopsy are indicated for further evaluation. (orig.)

There was atrauma history initiating symptoms in 14 patients (21.5 %. Neurological symptoms presentedsignificantly earlier in patients who had measles before 2 years of age compared to others(p0.05. The clinical stage of the patients at admission was determined based on Risk veHaddad classification. The most frequent stage was IIA (21 patients, 32.2%, IIC (17patients, 26.2% and IIB (16 patients, 24.6%. At the follow-up period, 46 (71% patients wasdepended to bed. The mean time interval between SSPE initiation age and bed dependencywas 4.68 ± 4.05 months (1-17 months.Of the 31 patients who underwent cranial magnetic rezonans imaging (MRI, 15patients (48.38% had pathological findings, the most frequent findings were cortical vesubcortical lesions. Of the 24 patients who underwent cranial tomographi, 22 (91.6% werenormal. Of the remaining two, one had atrophy and the other had increase in contrast. All ofthe patients underwent rutine EEG test. Fifty-four (83.1% of these had periodic complexhigh slow wave activity.The clinical findings and Electro Encephalographi results are important parameters inthe diagnosis of SSPE. Cranial tomographi is not useful in the diagnosis of SSPE. However,cranial MRI findings is pathologic only in the half of the patients.

    Musculoskeletal fibromatoses represent a wide spectrum of fibroblastic and myofibroblastic neoplasms with similar pathologic appearances and variable clinical behavior. These lesions can be categorized by location (superficial or deep) or by the age group predominantly affected. Superficial fibromatoses in adults (palmar and plantar) and children (calcifying aponeurotic fibroma, lipofibromatosis, and inclusion body fibromatosis) are often small slow-growing lesions; their diagnosis is suggested by location. Deep fibromatoses in adults (desmoid type and abdominal wall) and children (fibromatosis colli and myofibroma and myofibromatosis) are frequently large and more rapidly enlarging; location of these lesions may be nonspecific. Radiographic findings typically are nonspecific. Cross-sectional imaging (ultrasonography, computed tomography, or magnetic resonance [MR] imaging) reveals lesion location, extent, and involvement of adjacent structures for staging and evaluation of local recurrence. MR imaging findings of predominantly low to intermediate signal intensity, nonenhancing bands of low signal intensity on long repetition time MR images that represent collagenized regions, and extension along fascial planes ("fascial tail" sign) add specificity for diagnosis. Additional features that aid in diagnostic specificity include an abdominal wall location related to pregnancy (abdominal wall fibromatosis), a lower neck location in a young child (fibromatosis colli), an adipose component (lipofibromatosis), or multiple lesions in young children (myofibromatosis). Treatment may be conservative or surgical resection, depending on the specific diagnosis. Local recurrence is common after surgical resection owing to the infiltrative growth of these lesions. Recognition that the appearances of the various types of musculoskeletal fibromatoses reflect their pathologic characteristics improves radiologic assessment and helps optimize patient management.

    Full Text Available This is a case report of suicidal ingestion of chlorfenapyr, presenting with neurological complications after a latent period of more than a week, and rapidly progressing to death within days of symptoms. Chlorfenapyr is a moderately hazardous pesticide according to World Health Organization toxicity classification, and kills target organism by depriving it of energy through interference with oxidative phosphorylation at mitochondrial level. A pro-pesticide, chlorfenapyr takes time to convert to its active form and either this active form or a toxic metabolite causes delayed neurological symptoms. It causes significant neurotoxicity in rat models. This case report provides for the first time from India (second worldwide, clinical and "radiological evidence" (magnetic resonance imaging showing demyelinating/oedematous changes of "chlorfenapyr neurotoxicity in humans." It also highlights the "latent period" between ingestion and onset of fatal manifestations. Earlier, similar case reports of human deaths with delayed onset neurological symptoms, due to chlorfenapyr poisoning have been reported, from Japan, Columbia, and Korea.

  19. Abdominal tuberculosis, clinical-radiological revision

    International Nuclear Information System (INIS)

    We retrospectively evaluated the clinical charts and diagnostic images of hospitalised patients with histological or bacteriologic demonstration of abdominal tuberculosis (TB) including those with probable abdominal TB, who had pulmonary TB and radiologic findings highly suggestive of abdominal TB with favourable response to treatment. Cases with genitourinary TB were excluded. We found 24 patients with an average age of 25 yrs. In some cases this entity was not suspected on the imaging studies, and diagnosis was made on surgery. The most frequent symptoms were: abdominal pain, diarrhoea, fever, vomiting, weight loss and abdominal mass. Active pulmonary TB was demonstrated on 8 cases (33%) Peritoneal presentation was the most frequent (54%) with septated or simple ascites, cystic ascites or pseudocysts within bowel loops. Mesenteric involvement (21 %) showed adenopathy or masses identified with CT. Intestinal forms (17%) showed pseudo-polyps on terminal ileum and ulcers on ileum, cecum and colon. We found one case with diffuse ulcerative involvement of the colon. Two cases showed hepatic involvement, one with an abscess and a tuberculosis Cole cystitis, with pyloric syndrome due to fibrosis

    This article presents the general causes of preanalytic variability with a few examples showing specialists and practitioners that special and improved care should be given to this too often neglected phase. The preanalytic phase of clinical pathology includes all the steps from specimen collection to analysis. It is the phase where most laboratory errors occur in human, and probably also in veterinary clinical pathology. Numerous causes may affect the validity of the results, including technical factors, such as the choice of anticoagulant, the blood vessel sampled, and the duration and conditions of specimen handling. While the latter factors can be defined, influence of biologic and physiologic factors such as feeding and fasting, stress, and biologic and endocrine rhythms can often not be controlled. Nevertheless, as many factors as possible should at least be documented. The importance of the preanalytic phase is often not given the necessary attention, although the validity of the results and consequent clinical decision making and medical management of animal patients would likely be improved if the quality of specimens submitted to the laboratory was optimized.

    We evaluated the usefulness of the whole-mount section of the inflated-fixed lung specimen in the study of radiologic-pathologic correlations. Altogether, 24 resected fresh lobe specimens with 1.5- to 3.0-cm solitary pulmonary carcinomas or tuberculomas were inflated with air, intrabronchially fixed by infusing Heitzman's solution, and finally cut into 10- to 15-micron-thick whole-mount sections for the histopathological examination. All 24 inflated-fixed lobes were satisfactorily soft as sponge, sufficiently springy, and kept their original shape. All whole-mount sections clearly presented the complete morphological features of the whole lobes, and could be directly observed by the naked eye and examined under microscopy. The use of the whole-mount section of the lung specimen may facilitate precisely and effectively the studies of the radiologic-pathologic correlations. PMID:8872075

    Infantile hemangiomas demonstrate a pattern of proliferative growth in infancy followed by a slow phase of involution. In contrast a rare type of vascular tumor, intramuscular capillary-type hemangioma, usually presents beyond the period of infancy with nonspecific symptoms and no evidence of involution. The purpose of this study was to characterize the clinical, imaging, histopathological characteristics and management of intramuscular capillary-type hemangioma. We performed a retrospective review of a 20-year period to identify children diagnosed with intramuscular capillary-type hemangioma. Patient demographics, imaging and histopathological findings were recorded. We included 18 children (10 boys, 8 girls) with histologically proven intramuscular capillary-type hemangioma - and adequate imaging. The mean age at presentation was 8.1 years (range 1 day to 19 years). Twelve lesions involved muscles of the extremities, 4 were located in the trunk and 2 were in the head and neck. MRI had been performed in all children and demonstrated a soft-tissue mass with flow voids, consistent with fast flow. The lesion was well-circumscribed in 16 children and intralesional fat was seen in 14. Doppler US demonstrated a heterogeneous lesion, predominantly isoechoic to surrounding muscle, with enlarged arterial feeders. Enlarged feeding arteries, inhomogeneous blush and lack of arteriovenous shunting were noted on angiography (n = 5). The most common histopathological findings were lobules of capillaries with plump endothelium and at least some adipose tissue. The lesions were excised in six children. Two children were lost to follow-up. In the remaining 10, follow-up MRI studies ranging from 3 months to 10 years showed that the lesion enlarged in proportion to the child (n = 7), demonstrated slow growth (n = 2) or remained stable (n = 1). There was no change in imaging characteristics on follow-up. Intramuscular capillary-type hemangioma is a rare benign vascular tumor of

    Vascular tumours of the breast are especially rare in men, and a majority of them are angiosarcomas. In fact, we found only four cases of haemangioma in males in the literature. We present a case of cavernous haemangioma in a male aged 48 years, and which commenced as a palpable mass. We performed differential diagnosis and radiological-pathological correlation. We established the correct classification of this case histologically, and decided on the definitive therapeutic approach. (orig.)

    This study investigated whether extent of surgical resection (Simpson and Shinshu grade) along with pathological and radiological factors influence the tumor control and recurrence-free survival (RFS) of patients with World Health Organization (WHO) grade II meningiomas. The clinical, radiological and surgical notes on the 59 patients with WHO grade II meningioma managed at our institution over 20years were retrospectively reviewed. In this study, median survival time was 41months. The overall recurrence rate in Simpson grades I and II resection was 31%. In grades III and IV, the overall recurrence rate was 73%, and this high recurrence rate in these groups was confined within 5years. In Cox regression analysis, combined data of grades (I and II)/complete resection showed a significant difference in RFS compared to grades (III and IV)/subtotal resection (p=0.0001). A similar trend of RFS (p=0.0001) was observed with the Shinshu grading system of resection. In addition, a Ki-67% marker for proliferation less than 15% (p=0.029), absence of certain radiological features including heterogeneous enhancement, cyst formation and peritumoral edema (p=0.006), and repeat surgery for recurrent meningioma was associated with better survival (p=0.014). However, radiosurgery did not have a beneficial role in the treatment of recurrence of atypical meningioma. The Simpson grading system is the primary predictor of recurrence of WHO grade II meningioma after resection. In addition, certain pathological and radiological features need to be considered as possible factors of recurrence after resection. Lastly, depending on the likely risks and surgical morbidity, repeat surgical resection should be performed for recurrent atypical meningioma.

    The spondylolysis is a defective ossification in the pars interarticularis of the neural arches without displacement of the vertebral body and it sometimes confuses with other spinal lesions complaining of low back pain. The authors analyzed with clinical observations in 88 cases of spondylolysis diagnosed radiologically at B.N.U.H. from January 1977 to August 1978. The results obtained as follows: 1. Among 88 cases of the spondylolysis, the highest incidence of the age was second decade in 55.7%, and the sex ratio was 4.2 to 1 in male to female. 2. The prominent symptoms were a low back pain in 71.6%, the radiating pain with the low backache in 27.3% and the paresis of low extremities in 1.2%. 3. The frequent sites of the involvement were fifth lumbar vertebra in 83.6%, fourth lumbar vertebra in 9.8%, third lumbar vertebra in 5.5%, first lumbar vertebra in 1.1% and second lumbar vertebra in zero. 4. Bilateral lesions were in 68.2% and unilateral lesion was 20.9% in the right side and 10.9% in the left. 5. The combined abnormal findings of the spine were spondylitis in 36.1%, suspicious H.N.P. in 27.8%, spondylolisthesis in 25.0%, spina bifida in 8.3% and lumbarization in 2.8% in that order. 6. The cause of spondylolysis are still uncertain, but we are experienced 9 cases (10.3%) in the definite history of the trauma.

    Objective To investigate the clinical pathological feature and diagnostic criteria of tongue amyloidosis (AL).Methods During 1992 to 2005, 25 patients pathologically diagnosed as tongue AL in our hospital were reviewed retrospectively, and all of them had no enlarged tongue. Haematoxylin and eosin (HE) and immunohistochemical staining were used to detect the amyloid deposition on the tongue.Results Totally 84 % (21/25) patients had symptoms of xerostomia and taste-blindness, 44 % (11/25) patients complained of activity limitation of tongue. Macroscopic observation showed mucosa pallescence, punctuate hemorrhage, red grain particles, and ulcers on the tongue. HE staining indicated amyloid depositions in basement membrane,muscle cell, vessel wall, and nerve fiber. Immunohistochemical study demonstrated kappa light-chain deposition in 64%(16/25) cases, and lambda light-chain deposition in 36 % (9/25) cases. They presented in vessel wall, nerve fiber, and muscle cells.Conclusion The biopsy is an important means for the diagnosis of early tongue AL, and the wide variety of amyloid light chain is helpful to differential diagnosis.

    Pachyonychia congenita (PC) is a rare genodermatosis affecting the nails, skin, oral mucosae, larynx, hair, and teeth. Pathogenic mutations in keratins K6a or K16 are associated with the PC-1 phenotype whereas K6b and K17 mutations are associated with the PC-2 phenotype. Analysis of clinical, pathological, and genetic data from the literature and two research registries reveal that >97% of PC cases exhibit fingernail and toenail thickening, and painful plantar keratoderma. Prospective evaluation of 57 PC patients from 41 families revealed variable clinical findings: hyperhidrosis (79%), oral leukokeratosis (75%), follicular keratosis (65%), palmar keratoderma (60%), cutaneous cysts (35%), hoarseness or laryngeal involvement (16%), coarse or twisted hair (26%), early primary tooth loss (14%), and presence of natal or prenatal teeth (2%). Stratification of these data by keratin mutation confirmed the increased incidence of cyst formation and natal teeth among PC-2 patients, although cysts were more commonly seen in PC-1 than previously reported (25%-33%). Previously unreported clinical features of PC include development of painful oral and nipple lesions during breastfeeding, copious production of waxy material in ears, and inability to walk without an ambulatory aid (50%). Possible pathogenic mechanisms are discussed with respect to the clinicopathologic and genetic correlations observed.

    To determine whether benign and malignant bone tumors with associated pathologic fractures can be differentiated using radiologic findings. Seventy-eight patients (47 men and 31 women, age range: 1-93 years) with a bone tumor and an associated pathologic fracture from 2004 to 2013 constituted the retrospective study cohort. The tumor size, margin, and enhancement patterns; the presence of sclerotic margin, the peritumoral bone marrow, soft tissue edema, extra-osseous soft tissue mass, intratumoral cystic/hemorrhagic/necrotic regions, mineralization/sclerotic regions, periosteal reaction and its appearance; and cortical change and its appearance were evaluated on all images. Differences between the imaging characteristics of malignant and benign pathologic fractures were compared using Pearson's chi-square test and the 2-sample t-test. There were 22 benign and 56 malignant bone tumors. Some factors were found to significantly differentiate between benign and malignant tumors; specifically, ill-defined tumor margin, the presence of sclerotic tumor margin and an extra-osseous soft tissue mass, the absence of cystic/necrotic/hemorrhagic portions in a mass, the homogeneous enhancement pattern, and the presence of a displaced fracture and of underlying cortical change were suggestive of malignant pathologic fractures. Some imaging findings were helpful for differentiating between benign and malignant pathologic fractures.

    2013-07-01

    Tablet computing and mobile resources are the hot topics in technology today, with that interest spilling into the medical field. To improve resident education, a fully configured iPad, referred to as the "Radiology Resident iPad Toolbox," was created and implemented at the University of Colorado. The goal was to create a portable device with comprehensive educational, clinical, and communication tools that would contain all necessary resources for an entire 4-year radiology residency. The device was distributed to a total of 34 radiology residents (8 first-year residents, 8 second-year residents, 9 third-year residents, and 9 fourth-year residents). This article describes the process used to develop and deploy the device, provides a distillation of useful applications and resources decided upon after extensive evaluation, and assesses the impact this device had on resident education. The Radiology Resident iPad Toolbox is a cost-effective, portable, educational instrument that has increased studying efficiency; improved access to study materials such as books, radiology cases, lectures, and web-based resources; and increased interactivity in educational conferences and lectures through the use of audience-response software, with questions geared toward the new ABR board format. This preconfigured tablet fully embraces the technology shift into mobile computing and represents a paradigm shift in educational strategy. PMID:23647869

  17. Effectiveness of a radiology-anatomy instructional module in a clinical course on oral radiology

    International Nuclear Information System (INIS)

    An insufficient knowledge of anatomy often complicates the interpretation of radiological findings by students learning clinical medicine. During a 3-week clinical course in oral radiology, students attended lectures on anatomy for half of each day. Our objectives were to evaluate this program and determine why some students remained unmotivated to learn anatomy. Surveys were carried out using two questionnaires, one for evaluating the students' beliefs regarding the necessity of knowing anatomy and their understanding of radiology and anatomy, and the other for determining the value of the educational program. In total, 126 questionnaires were analyzed. Structural equation modeling and decision analysis were used to analyze the data obtained. Beliefs regarding the necessity of knowing anatomy were explained by three variables: the necessity of knowing imaging anatomy, the necessity of knowing gross anatomy, and understanding of anatomy. Awareness of the necessity of knowing anatomy and understanding of graphical images were not strongly correlated. The educational program was characterized by two factors: 'value' and 'appropriateness' These were strongly correlated. Student interest in the content of the course was found to be the most important factor in student evaluations of the educational program. Students who answered 'agree', 'disagree' or 'strongly disagree' to three items, interested in the content of the course', 'obtained knowledge through the course' and 'expected the course to be useful in the near future were likely to have insufficient understanding of and awareness of the necessity of radiology and anatomy. The inclusion of lectures on anatomy is beneficial for improving student understanding of oral radiology. Student interest in the content is important in evaluations of radiology-anatomy programs.

    2011-02-01

    The Society of Toxicologic Pathology (STP) and American Society for Veterinary Clinical Pathology (ASCVP) convened a Clinical Pathology in Carcinogenicity Studies Working Group to recommend best practices for inclusion of clinical pathology testing in carcinogenicity studies. Regulatory guidance documents and literature were reviewed, and veterinary pathologists from North America, Japan, and Europe were surveyed regarding current practices, perceived value, and recommendations for clinical pathology testing in carcinogenicity studies. For two-year rodent carcinogenicity studies, the Working Group recommends that clinical pathology testing be limited to collection of blood smears at scheduled and unscheduled sacrifices to be examined only if indicated to aid in the diagnosis of possible hematopoietic neoplasia following histopathologic evaluation. Additional clinical pathology testing is most appropriately used to address specific issues from prior toxicity studies or known test article-related class effects. Inadequate data were available to make a recommendation concerning clinical pathology testing for alternative six-month carcinogenicity assays using genetically modified mice, although the Working Group suggests that it may be appropriate to use the same approach as for two-year carcinogenicity studies since the study goal is the same.

    Background The non-Hodgkin's lymphoma is the AIDS symbol of tumor, with high incidence and poor prognosis. The purpose of this study was to investigate the radiological demonstrations of AIDS complicated by intestinal lymphoma and its pathological mechanism.Methods CT scan and pathological data of 3 cases of AIDS complicated by intestinal lymphoma were retrospectively analyzed. All the 3 cases received CT diagnostic scanning, including 2 receiving barium enema radiography after lower gastrointestinal tract cleansing, 1 receiving laporotomy to obtain partial thickened intestinal canal for histopathology and 1with autopsy for histopathological analysis.Results Intestinal canal lymphoma occurred at the left intestinal canal in 2 cases and at the right intestinal canal in the other case, with manifestations of unevenly thickened intestinal canal wall, narrowed canal lumen and filling defect. It was pathologically classified as B cell lymphoma.Conclusions AIDS complicated by B cell lymphoma has manifestations of unevenly thickened intestinal canal wall and narrowed canal lumen, which are non-specific. It should be differentiated from other tumors of intestinal canal in its diagnosis.

    This comprehensive reference work presents in-depth information on the diagnostic radiology and endoscopy of the colon. After a brief review of the history of colon examinations, two chapters explain the anatomy, physiology and pharmacology of the large intestine as well as the methods and techniques applied for radiological examination of the colon. The pathology and characteristical findings and the diagnostic evaluation of the various types of disease are the main subject, with the chapters discussing inflammations and tumors consuming by far most of the space, but there is also valuable information on vascular lesions, traumata, latrogenous or post-surgery lesions, among others, and on the characteristical findings in children. Numerous tables, radiographs and endoscopic images together with drawings illustrate and accompany the textbook information. (orig.). 492 figs., 95 tabs.

  2. Interventional radiology as clinical specialty and how this affects the radiology specialty as a whole

    International Nuclear Information System (INIS)

    Full text: Interventional Radiologists (IRs) are medical doctors who are trained in imaging but have undergone additional specialist training in highly demanding image-guided techniques. For this reason they play an increasingly important clinical role which is expanding beyond IR/angiography suite. As IR practice is fundamentally different from diagnostic imaging, the Radiology departments should be adapted to facilitate this special task. Interventional Radiologists should be able to fulfil their task as patient’s primary doctor and exert direct clinical responsibility for the patient under their care. They should be able to clinically assess and counsel patients before a procedure, inform them about the risks of the procedure and possible alternative treatment options, obtain valid consent and follow-up them after the procedure. they should also effectively communicate with referring physicians and develop strategies to deal with complex clinical situations and difficult clinical scenarios. In this context it is imperative for IRs to participate regularly in multidisciplinary clinical meetings and multidisciplinary forums to ensure optimum care. As clinicians, IR’s must be involved with the day to day management of their patients’ care to ensure optimal outcomes for patients. This may involve shared care with a broad range of specialists, however IR’s should aim to have direct access to inpatients beds where they can admit and discharge patients as necessary, with sufficient time allocated for this activity. As the number and demand of IR day cases steadily increases, IR units should organize day case facilities staffed with nursing and clerical staff which can result in major cost savings to hospitals. In this context the Head of Radiology department should convince hospital authorities to establish outpatient clinic facilities with nursing and clerical support where referred patients can be counselled and reviewed in a quiet environment.

    Adenoid cystic carcinoma (ACC) is a subtype of adenocarcinoma that is usually seen in the salivary glands. It has also been reported in other organs including the breast, skin, tracheobronchial tree, cervix, larynx, and Bartholin gland. ACC in the breast is rare, accounting for less than 0.1% of all breast cancers. Furthermore, the imaging characteristics of ACC of the breast have not been well described in the literature, especially regarding the findings with magnetic resonance imaging (MRI). Here, we report radiologic findings of a rare case of ACC in the breast by mammography, sonography, computed tomography (CT), positron emission tomography/CT, and MRI with pathologic correlation and a review of the literature.

    Aim: We compared radiological assessment with pathological diagnoses in 500 consecutive vacuum-assisted breast biopsies performed for microcalcifications. Methods: Lesions were biopsied using a 11-gauge mammotome device. Before biopsy, microcalcifications were classified according to the Breast Imaging Reporting and Data System (BI-RADS). Histopathological and radiological diagnosis were compared. Results: Histopathology revealed 333 (67%) benign lesions. Benign lesions were classified as BI-RADS 3 in 19%, and as suspicious in 35%. 167 lesions (33%) were malignant. Malignant lesions were classified as suspicious or highly suggestive of malignancy in 63%. Frequency of malignancy in BI-RADS categories 4 and 5 was 35% and 100%, respectively. In BI-RADS 3 microcalcifications, the malignancy frequency was 19%. The mammographic features with the highest positive predictive value for malignancies were pleomorphic morphology (42%) and a linear or segmental distribution (51%). The microcalcification morphology was not reliably able to predict malignancy. Conclusion: In this study, BI-RADS 3 microcalcification lesions had a malignancy rate that is higher than previously reported. Vacuum-assisted biopsy is useful in any indeterminate and suspicious microcalcifications and provides maximum information before any operative intervention.

    Objective To investigate the etiology, pathology, and mechanism of pathogenesis of Moyamoya disease.Methods A total of 15 human autopsies were analyzed. In addition, in order to create an animal model of the disease, 21 Japanese rabbits were divided randomly into two groups and subjected to injections of horse serum either intravenously or locally in the area of the sympathetic ganglia. Pathological and immunohistochemical characteristics were observed.Results The pathological features of the autopsies and the animal models both involved intima hyperplasia and stenosis or even occlusion of the lumen in the terminal ends of the internal carotid artery and the anterior and middle cerebral arteries. Disconnections or even breakages of the inner layer of the lumen were also observed, without an obvious inflammatory response. Hyperplasic smooth muscle cells of the medial membrane had extended inward through broken portions of the internal elastic lamina, with intima cell hyperplasia resulting in lumen stenosis. The hyperplastic vascular walls were positive for IgG and IgM.Conclusions The etiology of Moyamoya disease may involve allergic angiitis. A possible mechanism is that proximal portions of the circle of Willis first develop chronic stenosis or occlusion, leading to compensatory small vessel proliferation, which perforates into the cerebral parenchyma.

    International Nuclear Information System (INIS)

    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

    Full Text Available Fascioliasis is a worldwide but unevenly distributed zoonosis caused by the trematode Fasciola hepatica that infects do­mesti­cated herbivores. Fasciolosis also occurs accidentally in humans by ingestion of metacercaria-laden freshwater or water plants. Human infections are common in developing countries and are not rare in Europe. The clinical course has been con­ventionally described in two phases: an acute phase of hepatic parenchymal invasion of an immature worm larva (parenchy­mal phase and a stationary phase after residence in the bile duct and production of eggs (ductal phase. We report a 34 years old woman from Ilam, western Iran with hepatic disorder, RUQ pain, and jaundice. The diagnosis was made by sonography, CT scan and serologic studies. Serologic exam (ELISA was positive & CT findings were compatible with fascioliasis.

    International Nuclear Information System (INIS)

    Diagnostic radiology is still the foremost of all innovative medical disciplines. This has many advantages but also some handicaps, e.g. the siting problem of medical equipment whose clinical potential is not fully known. This applies in particular to nuclear spin tomography, where the Laender governments and the Scientific Council seen to agree that all universities should have the appropriate equipment as soon as possible in order to intensify interdisciplinary research. Formerly, in the case of computerized tomography, there was less readiness. As a result, the siting of CT equipment is less organically structured. A special handicap of innovative fields is the problem of training and advanced training. The Chamber of Medicine and the Association of Doctors Participating in the Health Insurance Plan have issued regulations aimed at a better standardisation in this field. (orig.)

  15. Radiology as part of an objective structured clinical examination on clinical skills

    International Nuclear Information System (INIS)

    Introduction: An objective structured clinical examination (OSCE) assessess clinical competence in a standardised and context related manner. Compared with written tests, OSCE's are more susceptible to reliability errors because of the use of multiple cases and multiple examiners. In the pre-clinical phase of the medical curriculum of the University Medical Centre Utrecht, an OSCE is organised as a medical consult. We evaluated the radiology station. Method: Four questions were formulated: ·What is the internal consistency of the items of the radiology station? ·How do the scores on the radiology station compare with the scores on the test excluding radiology? ·How do different cases differ in scores? ·What are the differences in score between the examiners? We analysed the OSCE results of second year medical students in 2004. Results: Two hundred and sixty-five students were examined in the OSCE in 2004. Ninty-three Students were examined in the radiology station. Cronbach's alpha coefficient for the radiology station was 0.92. The average score for the radiology station was 3.8 (0.87). The average score for the test without radiology was 3.9 (0.32). The range of the average scores for the six different cases was 0.5 (3.6-4.1). The range of the average scores for the five examiners was 1.0 (3.3-4.3). Conclusion: The internal consistency of the items in the radiology station is good. The average score for the radiology station is similar to that of the other stations. The range of the scores between the different cases was relatively small. The range of the scores between the different examiners was clearly larger.

    Kidney, Beverly A; Dial, Sharon M; Christopher, Mary M

    2009-09-01

    The Education Committee of the American Society for Veterinary Clinical Pathology has identified a need for improved structure and guidance of training residents in clinical pathology. This article is the third in a series of articles that address this need. The goals of this article are to describe learning objectives and competencies in knowledge, abilities, and skills in cytopathology and surgical pathology (CSP); provide options and ideas for training activities; and identify resources in veterinary CSP for faculty, training program coordinators, and residents. Guidelines were developed in consultation with Education Committee members and peer experts and with evaluation of the literature. The primary objectives of training in CSP are: (1) to develop a thorough, extensive, and relevant knowledge base of biomedical and clinical sciences applicable to the practice of CSP in domestic animals, laboratory animals, and other nondomestic animal species; (2) to be able to reason, think critically, investigate, use scientific evidence, and communicate effectively when making diagnoses and consulting and to improve and advance the practice of pathology; and (3) to acquire selected technical skills used in CSP and pathology laboratory management. These guidelines define expected competencies that will help ensure proficiency, leadership, and the advancement of knowledge in veterinary CSP and will provide a useful framework for didactic and clinical activities in resident-training programs.

    * Conventional automated interpretative reporting systems use standard or "canned" comments for patient reports. These are result-specific and do not generally refer to the patient context. * Laboratory information systems (LIS) are limited in their application of patient-specific content of reporting. * Patient-specific interpretation requires extensive cross-referencing to other information contained in the LIS such as previous test results, other related tests, and clinical notes, both current and previous. * Expert systems have the potential to improve reporting quality by enabling patient-specific reporting in clinical laboratories.

  20. Idiopathic granulomatous mastitis; Clinical presentation, radiological features and treatmant

    International Nuclear Information System (INIS)

    To determine the clinical characteristic, clinical presentations and radiological features of diopathic granulomatous mastitis, and the best treatment approaches of this clinical entity. Between 1996 and 2003 the files and histopathology reports of 25 patients with granulomatous mastitis at King Abdul-Aziz University Hospital Jeddah, Kindom of Saudi Arabia were reviewed. The data were analyzed and a Medline search was carried out from 1970 to 2003 to review relevant cases. The age of patients ranged from 24-66 years and the mean age was 36.6+-9.43 years. All patients were females. The most common clinical presentation was palpable tender mass. The most common mammographic finding was ill-defined mass. However, mixed hypo- and hyper-echogenic lesions with tubular connections were the common ultrasonic findings. Treatment approaches were conservative or surgical excision or steroid. Conservative treatment associated with the higher rate of complications, while treatment with steroid showed complete remission of disease. Idiopathic granulomatous mastitis is a rare, benign breast disease that is usually underestimated or misdiagnosed. The clinical and radiological features resemble those of infectious mastitis or breast carcinoma. Early recognition and initiation of steroid treatment will result in complete remission of the disease and prevent complications. (author)

    Full Text Available In recent years, vertebral artery dissection (VAD is reported more frequently as a cause of young cerebrovascular accidents. It can occur spontaneously or following a neck manipulation and trauma. The patients were 3 females (mean age: 35±26 years and 7 males (mean age: 37.71±4.96 years. Only 2 patients described neck trauma. Cerebellar findings were prominent in all cases. On radiological investigation, vascular changes of vertebral arteries were detected bilaterally in 2 cases, right in 5 and left in 3 cases. All the cases were treated with anticoagulant therapy and cured but 1 with sequela. Prognosis of vertebral artery dissection is generally good by early diagnosis and treatment. In this article, we reported clinical and radiological properties of 10 vertebral artery dissection cases.

    The aim of this study was to investigate corticobasal syndrome with respect to underlying pathologies, the ability of current clinical criteria to detect early stages of disease, and symptoms and signs predicting background pathologies. We retrospectively analyzed the clinicopathological findings from patients with corticobasal syndrome. We also analyzed whether those findings fulfilled the diagnostic criteria for corticobasal degeneration (CBD). Finally, we investigated characteristic clinical features that are specific to each background pathology. Of 10 consecutive autopsied patients who had corticobasal syndrome (mean age ± standard deviation, 67.9 ± 9.3 years; male:female ratio, 6:4), three had corticobasal degeneration pathology, three had progressive supranuclear palsy, three had Alzheimer's disease, and one had atypical four-repeat tauopathy. Nine patients fulfilled Mayo criteria, and all 10 patients fulfilled modified Cambridge criteria at the later stage, but only two patients fulfilled either clinical criteria within 2 years of disease onset. Five patients fulfilled the clinical criteria for possible CBD (p-CBD), and one patient fulfilled the clinical research criteria for probable sporadic CBD (cr-CBD) at the later stage. Only two patients fulfilled the criteria for either p-CBD or cr-CBD within 2 years of disease onset. Although we could not find any predictive characteristic clinical features that were specific to CBD pathology, only patients with progressive supranuclear palsy developed apraxia of eyelid opening and cerebellar ataxia. Myoclonus and memory impairment, especially if they appear at an early stage of the disease, may predict Alzheimer's disease pathology. Sensitivity of the available clinical criteria for corticobasal syndrome was poor within 2 years of disease onset.

  7. [Sudeck disease--pathology, clinical aspects and therapy].

    1998-06-01

    In our opinion the etiology of Sudeck's disease (acute reflex bone atrophy) plays a decisive role in therapeutic planning. The therapy is based on clinical and radiological findings. Physiotherapy addresses the symptom complex of pain, hyperemia, edema formation, and limitations of movement which act in a vicious circle and its intensity is modified according to the prevailing clinical and possibly also radiological findings. A strict coupling of the therapy to a classification according to stage is not recommended. Pharmacological therapy is merely a supporting element and focuses on the sympathetic overexcitability. The best therapy for Sudeck's disease is prophylaxis. Interventions collected under the general term early functional mobilization are, especially after surgical measures, a major factor in the avoidance of neurovegetative dysregulation in the sense of sympathetic reflex dystrophy.

  8. Central giant cell granuloma of the jaws: clinical and radiological evaluation of 22 cases

    International Nuclear Information System (INIS)

    The objective was to investigate the clinical and radiological characteristics of central giant cell granulomas (CGCGs) of the jaws. A retrospective analysis of a 20-year database was performed regarding both clinical and radiological features of 22 patients affected with CGCGs of the jaws. Fourteen women and 8 men were included with the age range of 7-81 years (mean 31.7 years). Among the 22 lesions, 16 were located in the mandible and 6 in the maxilla. Painless swelling was the most common clinical feature in 18 of all cases. Limited mouth opening was noted in 2 patients where the lesions involved the condyle. Radiographically, 13 lesions were homogeneously osteolytic and 9 lesions were trabeculated. Fifteen lesions were unilocular and 14 lesions presented with well-defined but not sclerotic margins. CT images in 5 patients clearly showed the trabeculation within the lesions. The follow-up ranged from 1.5 to 11 years with a mean period of 5 years. Three out of 9 aggressive and 1 out of 13 nonaggressive lesions developed recurrence. Diagnosis of CGCGs of the jaws depends on both correct interpretation of clinical, radiographic and pathological data. Differentiation between aggressive and nonaggressive CGCGs should be considered to improve individual treatment planning. (orig.)

  9. Clinical Training of Medical Physicists Specializing in Diagnostic Radiology

    International Nuclear Information System (INIS)

    The application of radiation in human health, for both diagnosis and treatment of disease, is an important component of the work of the IAEA. The responsibility for the increasing technical aspects of this work is undertaken by the medical physicist. To ensure good practice in this vital area, structured clinical training programmes are required to complement academic learning. This publication is intended to be a guide to the practical implementation of such a programme for diagnostic radiology. There is a general and growing awareness that radiation medicine is increasingly dependent on well trained medical physicists based in the clinical setting. However, an analysis of the availability of medical physicists indicates a large shortfall of qualified and capable professionals. This is particularly evident in developing countries. While strategies to increase academic educational opportunities are critical to such countries, the need for guidance on structured clinical training was recognized by the members of the Regional Cooperative Agreement (RCA) for Research, Development and Training related to Nuclear Sciences for Asia and the Pacific. Consequently, a technical cooperation regional project (RAS6038) under the RCA programme was formulated to address this need in the Asia-Pacific region by developing suitable material and establishing its viability. Development of a clinical training guide for medical physicists specializing in diagnostic radiology started in 2007 with the appointment of a core drafting committee of regional and international experts. The publication drew on the experiences of clinical training programmes in Australia and New Zealand, the UK and the USA, and was moderated by physicists working in the Asian region. This publication follows the approach of the IAEA publication Training Course Series No. 37, Clinical Training of Medical Physicists specializing in Radiation Oncology. This approach to clinical training has been successfully tested

    To improve the diagnostic accuracy of sporadic spinocerebellar degeneration (SCD), we assessed the clinical and pathological data of 1494 consecutive autopsy cases. The number of patients who received a diagnosis of sporadic SCD (including multiple system atrophy) either clinically or pathologically was 19 (1.3%). We identified six cases with clinical misdiagnoses of SCD that were confirmed pathologically as progressive supranuclear palsy (PSP, four cases), basilar artery thrombosis (one case) and unclassified tauopathy (one case). The total number of patients who received a clinical diagnosis of sporadic SCD was 93 and the positive predictive value was 93.5%. We also identified 13 autopsy cases that were pathologically confirmed as SCD, but had been clinically misdiagnosed as having other disorders. Their clinical diagnoses comprised progressive supranuclear palsy (five cases) and Parkinson's disease (PD, four cases), as well as parkinsonism with dementia, amyotrophic lateral sclerosis, paraneoplastic syndrome and multiple cerebral infarction (one case each). The results indicate that it is often difficult to distinguish PSP and PD from SCD, because of the atypical combination of symptoms or atypical timing of the appearance of symptoms, such as severe autonomic failure, cognitive impairment, poor L-dopa responsiveness, early cerebellar signs and obvious vertical gaze palsy.

    Full Text Available The objective of this study was to present some clinical and radiological manifestations of PNS in relation to bronchogenic carcinoma (BC and to evaluate the usefulness of imaging findings in the diagnosis of asymptomatic BC. In the study group of 204 patients (146 male and 58 female with proven bronchogenic carcinoma, PNS was present in 18 (8.62% patients. The patients with PNS were divided into two groups. The first one consisted of 13 (72.2% patients with symptoms related to primary tumours while the second one consisted of 5 (27.7% patients with symptoms, at initial appearance, indicative of disorders of other organs and systems. The predominant disorder was Lambert-Eaton Syndrome, associated with small-cell carcinoma. Endocrine manifestations included: inappropriate antidiuretic hormone production syndrome (small-cell carcinoma, a gonadotropin effect with gynaecomastia and testicular atrophy (planocellular carcinoma, small-cell carcinoma, a case of Cushing Syndrome (small-cell carcinoma, and hyper-calcaemia, due to the production of the parathyroid hormone-related peptide, which was associated with planocellular carcinoma. A rare case of bilateral exophthalmos was found as PNS at adenocarcinoma. Digital clubbing and hypertrophic osteoarthropathy (HO were associated with planocellular and adenocarcinoma, while clubbing was much more common than HO, especially among women. The differences between the two groups were related to the time of PNS appearance. In the first group, PNS occurred late on in the illness, while in the second group, PNS preceded the diagnosis of BC. Alternatively, the disappearance of a clinical or a radiological manifestation of PNS after surgery or chemotherapy may be an indicator of an improvement in health or PNS may be the first sign of illness recurrence. Radiological manifestations of PNS in asymptomatic patients may serve as a useful screen for identifying primary BC. In symptomatic patients, it may be an

    Full Text Available Purpose. The aim of this study is to investigate the etiology and the clinical, microbiological, histopathological, and radiological findings of acquired dacryocystoceles. Methods. In this retrospective study, we reviewed the clinical records of 10 eyes of 8 patients with dacryocystoceles who underwent external dacryocystorhinostomy (DCR surgery. Etiology, presenting symptoms and radiological findings as well as microbiological and histopathological assessment results and outcome were analyzed. Results. The records of 8 patients with dacryocystoceles were included in this study. In the histopathological evaluations of the samples collected from the lacrimal sac wall, chronic inflammation was found in all biopsied samples and fibrosis was observed in two histopathological evaluations. Computerized tomography (CT imaging showed fluid collection separated from adjacent tissues by a thin rim, corresponding to dacryocystoceles in the sac. In the microbiological culture examination of samples collected from the fluid within the cyst, no bacterial growth in 5 eyes, gram-negative bacillus growth in 3 eyes, and gram-positive cocci growth in 2 eyes were found. Conclusions. Acquired dacryocystoceles were observed extremely rarely and a definite pathogenic agent could not be identified in any of the cases, either microbiologically or histologically, whereas chronic inflammation was detected in all cases in our study.

  14. Acute hematogenous osteomyelitis in young children - clinical and radiological features

    International Nuclear Information System (INIS)

    Acute hematogenous osteomyelitis is a bacterial infectious disease which mainly affects the paediatrics age group. The incidence seems to decline through the last decade. The authors analyzed the clinical, bacteriological and radiological features of acute hematogenous osteomyelitis in 49 young children. Their age ranged from 12 days to 2.9 years (19 new-born and 30 babies). The most affected locus was the femur (46.9 %), followed by the humerus (40.9 %) and tibia (6.2 %). The adjacent joint was involved in 38.8 %. Up to the third day after onset of symptoms were admitted 32 children (65.3 %). A bacteriological diagnosis has been achieved in only 19 cases (38.8 %) which underwent different surgical procedures. Staphylococcus aureus (9 children; 64.3 %) was the most common causative microbe. Radiological characteristic showed mainly widening of joints, destruction of cartilage, bone destruction and osteoporosis. The median duration of antibiotic therapy was 31 days. Nine children underwent needle aspiration while another 10 required locus incision or open surgery with debridement or sequestrectomy. Definitive clinical restoration was observed in 42 cases (85.7%). (authors)

    It is unknown why some infants with perinatal stroke present clinical symptoms late during infancy and will be identified as infants with presumed perinatal stroke. The risk factors and clinical and radiological data of 42 infants with presumed perinatal stroke (69% with periventricular venous infarction and 31% with arterial ischemic stroke) from the Estonian Pediatric Stroke Database were reviewed. Children with presumed perinatal stroke were born at term in 95% of the cases and had had no risk factors during pregnancy in 43% of the cases. Children with periventricular venous infarction were born significantly more often (82%) vaginally (P = .0213) compared to children with arterial stroke (42%); nor did they require resuscitation (P = .0212) or had any neurological symptoms after birth (P = .0249). Periventricular venous infarction is the most common type of lesion among infants with the presumed perinatal stroke. Data suggest that the disease is of prenatal origin. PMID:26446909

    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)

    Progressive supranuclear palsy (PSP) is a four-repeat tauopathy with tau-positive, argyrophilic tuft-shaped astrocytes (TAs). We performed a pathological and clinical investigation in 40 consecutive autopsied Japanese patients with pathological diagnoses of PSP or PSP-like disease. Unequivocal TAs were present in 22 cases, all of which were confirmed to be PSP. Such TAs were hardly detected in the other 18 cases, which instead exhibited tau-positive, argyrophilic astrocytes, appearing as comparatively small clusters with central nuclei of irregularly shaped, coarse structures (equivocal TAs). Cluster analysis of the distribution pattern of tau-related pathology for these 18 cases identified two subgroups, pallido-nigro-luysian atrophy (PNLA) Type 1 (n = 9) and Type 2 (n = 9), the former being distinguished from the latter by the presence of tau-related lesions in the motor cortex, pontine nucleus and cerebellar dentate nucleus in addition to the severely affected PNL system. The duration from symptom onset until becoming wheelchair-bound was significantly longer in PNLA Type 1. Immunoblotting of samples from the three disease conditions revealed band patterns of low-molecular-mass tau fragments at ∼35 kDa. These findings shed further light on the wide pathological and clinical spectrum of four-repeat tauopathy, representing PSP in the broad sense rather than classical PSP. PMID:25974705

    The aim of this study was to compare the clinical, radiological and histological findings in a large population of subjects enrolled during a multicentre study of idiopathic pulmonary fibrosis, with a focus on discordance between imaging and histologic diagnoses of usual interstitial pneumonia (UIP).Two independent radiologists retrospectively reviewed 241 subjects who underwent high-resolution computed tomography (HRCT) and surgical lung biopsies. HRCT findings were classified as UIP, possible UIP and inconsistent with UIP. Histological findings were classified as definite, probable, possible and not UIP.Of the 241 cases, 102 (42.3%) had HRCT findings of UIP, 64 (26.6%) had possible UIP and 75 (31.1%) were inconsistent with UIP. Among those with UIP on HRCT, 99 (97.1%) had histologically definite or probable UIP (concordant group), and 71 (94.7%) of those with "inconsistent" HRCT features had histologically definite or probable UIP (discordant group). Discordant subjects were slightly younger and less likely to be smokers than concordant subjects, but no survival differences were identified.In this population of patients enrolled with a diagnosis of idiopathic pulmonary fibrosis, 94.7% of those with HRCT findings "inconsistent with UIP" demonstrated histological UIP. This suggests that the term "inconsistent with UIP" is misleading. PMID:26917616

    Background. There is confusion in the radiological literature as to the site of abdominal calcification in cystic fibrosis (CF) with meconium ileus (MI) in neonates. Purpose. To correlate the site of radiographic abdominal calcification with histologic and operative findings. Materials and methods. A review of clinical, radiographic, surgical and histologic data in 58 neonates with CF and MI. Results. Abdominal calcification was identified in 15 (26 %) neonates: on an abdominal radiograph in 8 (13 %), at laparotomy in 3 and histologically in 10 (37 %) of the 27 resected specimens. The radiographic pattern of calcification varied from small specks in three cases to small, better-defined areas in two. In the other three patients, the calcification was more extensive and curvilinear. Histologically, calcification was found to be intramural in ten resected specimens, of which two also had intraluminal and one serosal calcification. The more extensive, curvilinear calcification identified radiographically correlated with histologically proven dystrophic intramural calcification. The less marked flecks or discrete areas of radiographic calcification may represent intramural, serosal or intraluminal calcification. Conclusion. Intramural calcification is common microscopically in CF with MI. Extensive radiographic calcification in these patients is more likely to represent intramural rather than serosal or intraluminal calcification. (orig.). With 4 figs.

    Inflammatory diseases of the maxillary sinuses affect up to 70% of the adult population. Odontogenic maxillary sinusitis represents 13-86% of the inflammatory processes of maxillofacial area, with the incidence range being explained rather by varying diagnosis criteria than the true incidence difference of odontogenic lesions. The aim of the study was to summarize the clinical and radiological characteristics of odontogenic sinusitis according to patients records in the Department of Maxillofacial Surgery of Omsk Clinical Hospital No11 and the oral surgery department of BUZ GKSP No1 in 2009-2014. A total of 948 records of patient (aged 17 to 68 years) with maxillary sinusitis were identified. X-ray examinations were performed by CT PISASSO TRIO ("KoYo", South Korea) and MSCT Brillians 6 and Brillians 64 ((Philips HealthCare), Netherlands). Images were obtained in axial projection with slice thickness of 0.2-0.6 mm with multiplanar reconstructions (MPR) in a variety of direct and oblique projections. Altogether 664 patients were diagnosed with foreign bodies in the maxillary sinuses (filling material in 569 cases, roots or root fragments? implants, rubber drains, fragments of endodontic instruments in 95 cases). In 284 persons odontogenic cysts were found. Almost every fifth case was complicated by mycotic infection. Analysis of the results showed that only a multidisciplinary approach including dentists, maxillofacial surgeons, otolaryngologists and radiologists, as well as dental volumetric tomography or multislice CT can ensure the correct clinical and radiological approaches to determine the tactics of treatment in patients with sinusitis, reduce the incidence of relapses and chronic inflammatory processes in the maxillary sinuses.

  3. Clinical fellowship training in pathology informatics: A program description

    Full Text Available Background: In 2007, our healthcare system established a clinical fellowship program in pathology informatics. In 2011, the program benchmarked its structure and operations against a 2009 white paper "Program requirements for fellowship education in the subspecialty of clinical informatics," endorsed by the Board of the American Medical Informatics Association (AMIA that described a proposal for a general clinical informatics fellowship program. Methods: A group of program faculty members and fellows compared each of the proposed requirements in the white paper with the fellowship program′s written charter and operations. The majority of white paper proposals aligned closely with the rules and activities in our program and comparison was straightforward. In some proposals, however, differences in terminology, approach, and philosophy made comparison less direct, and in those cases, the thinking of the group was recorded. After the initial evaluation, the remainder of the faculty reviewed the results and any disagreements were resolved. Results: The most important finding of the study was how closely the white paper proposals for a general clinical informatics fellowship program aligned with the reality of our existing pathology informatics fellowship. The program charter and operations of the program were judged to be concordant with the great majority of specific white paper proposals. However, there were some areas of discrepancy and the reasons for the discrepancies are discussed in the manuscript. Conclusions: After the comparison, we conclude that the existing pathology informatics fellowship could easily meet all substantive proposals put forth in the 2009 clinical informatics program requirements white paper. There was also agreement on a number of philosophical issues, such as the advantages of multiple fellows, the need for core knowledge and skill sets, and the need to maintain clinical skills during informatics training.

    The clinical and radiographic findings in 104 patients with chondroblastoma are presented. Pain was an almost constant presenting complaint, often accompanied in the case of para-articular lesions by impaired function of an adjacent joint. The majority (80%) were in long bones with a mean age of presentation of 16 years. The characteristic radiological image of these lesions was an eccentric radiolucency, having a sharply defined sclerotic margin and containing areas of calcification in approximately a third of cases. They were always related to a growth plate. Nearly half were confined to the affected epiphysis or apophysis itself, but most of the remainder had traversed the growth plate to involve also the adjacent metaphysis. The bones around the knee and the proximal ends of the humerus and femur were the sites of predilection. A minority (20%) affected flat bones and short tubular bones of the hand and foot, with a peculiar affinity for the calcaneus and talus. The mean age of presentation of these was 28 years. The radiological pattern was similar, except for a greater tendency to expand the affected bone. Complications included the formation of a secondary aneurysmal bone cyst in 16 cases (10 of them in long bones), one malignant chondroblastoma, and one fibrosarcoma developing after radiation of the original chondroblastoma.

    Introduction: We evaluated chest X-ray and clinical findings of patients with lower respiratory tract infection due to influenza H5N1 and presented the radiological findings and clinical course of the infection. Materials and methods: Between December 2005 and February 2006, eight hospitalized patients (median age 10, 5-15 years) with avian-flu were evaluated in this study. All patients were evaluated with chest X-ray and four of them with CT scan. Post mortem pathological characterization were also available for three of the patients. Results: A rapidly progressive pneumonia with high mortality rate was observed especially for cases with late admission. The major radiologic abnormalities were extensive pneumonic infiltration with segmental and multifocal distribution, mostly located in lower zones of the lung. No pleural effusion and hilar lymphadenopathy was noted. Conclusion: Avian flu may be presented as rapidly progressive pneumonia. The chest radiography has an important role in diagnosis and should be obtained daily because of rapid change of the findings that may necessitate prompt action.

    Full Text Available Background: In 2007, our healthcare system established a clinical fellowship program in Pathology Informatics. In 2010 a core didactic course was implemented to supplement the fellowship research and operational rotations. In 2011, the course was enhanced by a formal, structured core curriculum and reading list. We present and discuss our rationale and development process for the Core Curriculum and the role it plays in our Pathology Informatics Fellowship Training Program. Materials and Methods: The Core Curriculum for Pathology Informatics was developed, and is maintained, through the combined efforts of our Pathology Informatics Fellows and Faculty. The curriculum was created with a three-tiered structure, consisting of divisions, topics, and subtopics. Primary (required and suggested readings were selected for each subtopic in the curriculum and incorporated into a curated reading list, which is reviewed and maintained on a regular basis. Results: Our Core Curriculum is composed of four major divisions, 22 topics, and 92 subtopics that cover the wide breadth of Pathology Informatics. The four major divisions include: (1 Information Fundamentals, (2 Information Systems, (3 Workflow and Process, and (4 Governance and Management. A detailed, comprehensive reading list for the curriculum is presented in the Appendix to the manuscript and contains 570 total readings (current as of March 2012. Discussion: The adoption of a formal, core curriculum in a Pathology Informatics fellowship has significant impacts on both fellowship training and the general field of Pathology Informatics itself. For a fellowship, a core curriculum defines a basic, common scope of knowledge that the fellowship expects all of its graduates will know, while at the same time enhancing and broadening the traditional fellowship experience of research and operational rotations. For the field of Pathology Informatics itself, a core curriculum defines to the outside world

    Full Text Available Staging is of the utmost importance in the evaluation of a patient with non-small cell lung cancer (NSCLC because it defines the actual extent of the disease. Accurate staging allows multidisciplinary oncology teams to plan the best surgical or medical treatment and to predict patient prognosis. Based on the recommendation of the International Association for the Study of Lung Cancer (IASLC, a tumor, node, and metastases (TNM staging system is currently used for NSCLC. Clinical staging (c-TNM is achieved via non-invasive modalities such as examination of case history, clinical assessment and radiological tests. Pathological staging (p-TNM is based on histological examination of tissue specimens obtained with the aid of invasive techniques, either non-surgical or during the intervention. This review is a critical evaluation of the roles of current pre-operative staging modalities, both invasive and non-invasive. In particular, it focuses on new techniques and their role in providing accurate confirmation of patient TNM status. It also evaluates the surgical-pathological staging modalities used to obtain the true-pathological staging for NSCLC.

    The purpose of this study was to determine the current clinical environment in which interventional radiology (IR) is practiced throughout Europe. A survey, comprising 12 questions on IR clinical practice, was sent to 1800 CIRSE members. Members were asked to return one survey per department. Two hundred seventy-four departments returned completed questionnaires, 22% from the United Kingdom (n = 60), 11% from Germany (n = 30), 8% from Austria (n = 23), and the remainder spread over Europe. Experts, with more than 10 years of IR experience, comprised 74% of the survey group. Almost one-third of the radiologists dedicated more than 80% of their clinical sessions to IR alone (27%; n = 75), with two-thirds practicing in a university teaching hospital setting (66%; n = 179). Few institutions have dedicated IR inpatient hospital beds (17%; n = 46), however, to compensate, day case beds are available (31%), IR admitting rights are in place (64% overall, 86% for in-patients, and 89% for day cases), and elective IR admissions can be made through other clinicians (87%). IR outpatient clinics are run at 26% of departments, with an average of two sessions per week. Dedicated nurses staff the majority of IR suites (82%), but clinical junior doctors are lacking (46%). Hospital management\\'s refusing access to beds was the most commonly cited reason for not developing a clinical IR service (41%). In conclusion, there is marked variation across European centers in the current practice of IR. Half do not have dedicated junior doctors and only a small minority have inpatient hospital beds. If IR is to be maintained as a dedicated clinical specialty, these issues need to be addressed urgently.

  11. Assessment of radiation burden of premature infants and pathological newborns from radiological examinations

    International Nuclear Information System (INIS)

    We mapped radiological examination instrumentation at neonatal care departments and the most frequent types of examination and their parameters, and determined the input surface dose and compared them with limits recommended by the EC. Chest examination in the AP projection is the most frequent type of radiological examination. A number of parameters were found to exceed the recommended limits. The departments are urged to improve the instrumentation and procedures to reduce the infants' radiation burden to below the EC recommended limits. (orig.)

  12. Nasal polyps. A clinical radiological histopathological and mycological study

    International Nuclear Information System (INIS)

    Forty patients with nasal polyposis were studied. This study included clinical, haematological and mycological aspects. There were 24 females (60% of patients) and 16 males (40%). We found that all patients presented with nasal obstruction and nasal tone and the majority of them had allergic nasal symptoms such as sneezing and watery discharge. Thirty five percent of the patients were recurrent cases, being operated before for nasal polyps. Radiological investigations showed high of sinusitis and that 10% of the patients had complicated disease with orbital or intracranial extensions. Mycological studies revealed the presence of fungal infection in 4 patient (10%) and it was caused by Aspergillus flavus. Histological studies identified the allergic nature of the polyps in all patients. Surgical treatment was carried out in all patients and operations varied from simple intranasal polypectomy, intranasal ethmiodectomy, external ethmoidectomy to Caldwell-Luc operation for patients with antrochanal polyps.(Author)

    BACKGROUND: The clinical manifestations of Wernicke encephalopathy(WE) are atypical and short of effective auxiliary examination means. The effects of magnetic resonance imaging (MRI) in the diagnosis of WE have been reported suecessively. But its imageological detection needs to be further investigated.OBJECTIVE: To analyze the eharacteristics of clinical manifestations, skull MRI examination and pathological results in patients with WE.DESTGN: Retrospective analysis.SETTTNG: The General Hospital of Chinese PLA.PARTTCTPANTS: Ten patients of WE admitted to the Department of Neurology, General Hospital of Chinese PLA were recruited. Among them, five patients were diagnosed pathologically after death. Their pathological changes accorded with the pathological characteristics of WE. The other 5 patients were diagnosed clinically before death. Their pathological changes accorded with clinical and imageological manifestations and had definite reaction to the treatment of thiamine. Ten patients, 7 males and 3 females, were aged (47±13) years ranging from 33 to 73 years. Their disease courses averaged 6 weeks ranging from 3 to 10 weeks. They all were non-alcoholics. Four patients developed WE after acute pancreatitis, two patients after the recurrence of gastric cancer, two patients after cholecystectomy, one patient after hepatitis medicamentosa, one patient after Alzheimer disease. Informed consents were obtained from all the patients and their relatives.METHODS: After admission, clinical manifestations of patients were observed and recorded. Five patients underwent skull MRI examination and their detected results were recorded. Five dead patients underwent autopsy and brain pathological examinations. Neuropathological examination involved cerebrum, cerebellum and brain stem.MATN OUTCOME MEASURES: Clinical manifestations, MRI examination results, pathological analysis results and prognosis of all the patients.RESULTS: Ten patients with WE were involved in the final

    Objectives The aim of this study was to determine the level of evidence that is published in the oral and maxillofacial radiology (OMR) literature. Methods OMR papers published in Dentomaxillofacial Radiology and Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology and Endodontology between 1996 and 2005 were classified using epidemiological study design and diagnostic efficacy hierarchies. The country of origin and number of authors were noted. Results Of the 725 articles, 384 could be classified with the epidemiological study design hierarchy: 155 (40%) case reports/series and 207 (54%) cross-sectional studies. The distribution of study designs was not statistically significant across time (Fisher's exact test, P = 0.06) or regions (P = 0.89). The diagnostic efficacy hierarchy was applicable to 246 articles: 71 (29%) technical efficacy and 166 (67%) diagnostic accuracy studies. The distribution of efficacy levels was not statistically significant across time (P = 0.22) but was significant across regions (P < 0.01). Authors from Japan produced 26% of the papers with a mean ± standard deviation of 5.78 ± 1.98 authors per paper (APP); American authors, 23% (3.78 ± 1.72 APP); and all others, 51% (3.76 ± 1.51 APP). Conclusion The OMR literature consisted mostly of case reports/series, cross-sectional, technical efficacy and diagnostic accuracy studies. Such studies do not provide strong evidence for clinical decision making nor do they address the impact of diagnostic imaging on patient care. More studies at the higher end of the study design and efficacy hierarchies are needed in order to make wise choices regarding clinical decisions and resource allocations. PMID:21697152

    Full Text Available Pathologists and clinicians come together and exchange views, they instil in one another doubts, they break down barriers. Asphyxia, respiratory distress, sepsis, multi-organ failure (MOF, cerebral ischemia and neuroprotection, necrotizing enteritis, renal and biliary pathology (including congenital nephrotic syndrome, injury caused by drugs, cardiac decompensation, placental pathology, neonatal issues in mothers with tumor: these are the topics debated, in the true sense of the word, by perinatologists and pathologists. In some pathologies (e.g. MOF the pathophysiology is surprisingly the same in the neonate and the adult.  Different disciplines deal for example with immunohistochemistry and metabolomics with the processing of thousands of data in search of something that cannot be found with the classic criteria of anamnesis, objective examination, laboratory tests and imaging. Big data and information science promise to change the world. To come to grips with the extreme biological complexity of our organism and each of our organs, the completeness of enormous amounts of data is of extraordinary value if assessed holistically with the “omic” disciplines.

    To contribute our experience in the study of ductal carcinoma in situ of the breast (DCis), correlating the radiological and pathological features of the calcifications detected by mammography with their histological location within the tumor. Out of 24 cases of DCis, 20 diagnosed on the basis of calcifications detected on mammography (81%) were reviewed retrospectively. The authors assessed the radiological features of the calcifications such as cluster formation, number, distribution, size, shape and density. They were classified into three pathological subtypes, and the location of calcium within the tumor was studied. The histological data were correlated with the mammographic findings. Mammography showed that non segmented focal clusters were the most common type (13 of 20 cases) and that 45% of the tumors (9 of 20) presented 5 to 10 microcalcifications. Heterogeneity of size and shape predominated (80% and 75%, respectively) while 65% of the lesions had a round morphology. The histological findings showed that 95% of the microcalcifications were located in the interior of the tumor, and consisted of calcium with a necrotic component in grade III lesions, and calcium in the cribriform cells or micro papillae of the tumors in grades I and II. Microfocality and micro infiltration were detected in all three subtypes. There is a good radiologic-pathologic correlation of micro calcification in DCis. The calcifications observed in mammograms from grade I and II lesions are predominantly round-shaped and small in size. Histological analysis identifies them as laminated or psammomatous calcific depots in the cribriform cells or micropapillae of the tumor. In grade III lesions, the calcifications are rounded or elongated, and correspond to amorphous calcifications compressed of intra ductal necrotic tissue. (Author) 17 refs.

    Combining active recall testing with spaced repetition increases memory retention. The aim of this study was to evaluate and compare students' perception and utilization of an electronic spaced repetition oral pathology-radiology system in dental hygiene education and predoctoral dental education. The study employed an open-source suite of applications to create electronic "flashcards" that can be individually adjusted for frequency of repetition, depending on a user's assessment of difficulty. Accessible across multiple platforms (iOS, Android, Linux, OSX, Windows) as well as via any web-based browser, this framework was used to develop an oral radiology-oral pathology database of case-based questions. This system was introduced in two courses: sophomore oral pathology for dental students and sophomore radiology for dental hygiene students. Students were provided free software and/or mobile tablet devices as well as a database of 300 electronic question cards. Study participants were surveyed on frequency and extent of use. Perception-based surveys were used to evaluate their attitudes towards this technology. Of the eligible students, 12 of 22 (54.5%) dental hygiene and 49 of 107 (45.8%) dental students responded to the surveys. Adoption rates and student feedback were compared between the two groups. Among the respondents, acceptance of this technology with respect to educational usefulness was similar for the dental and dental hygiene students (median=5 on a five-point scale; dental hygiene interquartile range (IQR)=0; dental IQR=1). Only a minority of the survey respondents (25% dental, 33% dental hygiene) took advantage of one of the main benefits of this technology: automated spaced repetition. PMID:25838016

    Background Pathological fractures signify a potentially more aggressive subset of the original disease with higher misdiagnosis rates and inferior oncologic results.The purpose of the present study was to explore the clinical features of neoplastic pathological fracture in extremities.Methods From August 2002 to December 2010,a consecutive series of 139 patients suffering neoplastic pathological fracture were recruited,including 79 males and 60 females with a mean age of 31.3 years.Fractures were classified into five groups:tumor-like lesions (55),benign bone tumors (13),giant cell tumors (7),primary malignant bone tumors (28),and metastatic bone tumors (36).Based on their inducing forces,pathologic fractures were classified into four grades:spontaneous fracture,functional fracture,minor injury,and traumatic injury.Patients' age,fracture site,histological diagnoses,fracture forces,prodromes,and misdiagnosis were well reviewed.Kruskal-Wallis and x2 tests were used to compare forces and prodromes within different types of bone tumors.Results The highest pathologic fracture morbidity was 32.3% (45/139),which lay in the 11-20 year group,and 86.1%of metastatic tumors occurred in the 50-80 year group.The common sites of fractures were femur,humerus,and tibia.The fracture forces in benign bone tumors and tumor-like lesions are the strongest,followed by metastatic tumors and primary malignant bone tumors (Hc=80.980,P=0.000).Sixty-seven patients (48.2%) had local prodromes before pathologic fracture.The incidence rates of prodromes between primary malignant tumors and metastatic bone tumors had no significant difference (P=0.146),but they were all obviously higher than that of benign bone tumors and tumor-like lesions.Twenty patients experienced misdiagnosis.Conclusion Minor injury forces and local prodromes are clinical features of neoplastic pathologic fractures and they are also the critical factor avoiding misdiagnoses.

  20. Chronic recurrent multifocal osteomyelitis: an evolving clinical and radiological spectrum

    International Nuclear Information System (INIS)

    Based on radiographic and microscopic findings, three patients were prospectively diagnosed as having chronic recurrent multifocal osteomyelitis (CRMO). They form the basis of this report because of either the unusualness of the clinical presentation, hitherto undescribed associated diseases or the unusual age of presentation and sites of lesions. One patient developed pyoderma gangrenosum at the site of one of the skeletal lesions and then went on the develop ulcerative proctitis. A second patient presented with a soft tissue mass, which on MRI mimicked a sarcoma. The final patient presented with lesions in the wrist and phalanges of the toes at the unusual age of 38. None of the patients was treated with steroids or antibiotics for the skeletal lesions. Steroids were administered to one patient for treatment of pyoderma gangrenosum. The pattern and distribution of skeletal lesions in CRMO are well recognized in the pediatric age group. The unusual clinical and/or radiological features discussed herein suggests that this is a disease that continues to evolve with a broader spectrum of features than recognized. (orig./MG)

    International Nuclear Information System (INIS)

    Objective: To study the pathological morphologic characteristics of invasive pituitary tumor and the affect of vascularization to the tumor's invasion. Methods: One hundred and thirty cases of pituitary adenoma patients were divided into two groups, including invasive pituitary adenomas and non-invasive pituitary adenomas, and the clinical data of two groups were analysed and compared. Results : The difference was statistically significant between the invasive group and the non-invasive group in the incidence rate of pathological morphologic characteristics such as high nuclear cytoplasmic ratio, cell pleomorphism, nuclear atypia and nucleoli appearance (P<0.05); there were nuclear atypia and nucleolus margination in the invasive group through electron microscopy. And there was statistical significant difference in rate of MVD expression which was higher in the invasive group than that of noninvasive group (P<0.05). Conclusion: The pathological morphologic characteristics of pituitary tumor and the high expression of MVD are significantly reference valuable in tumor aggression diagnosis, which provides valuable indicators for early clinical diagnosis of tumor invasion.

  3. Evidence-based radiology: a new approach to evaluate the clinical practice of radiology

    International Nuclear Information System (INIS)

    Over the last several years, the concept and methodology of evidence-based medicine (EBM) have received significant attention in the scientific community. However, compared to therapeutic medical disciplines, EBM-based radiological publications are still underrepresented. This article summarizes the principles of EBM and discusses the possibilities of their application in radiology. The presented topics include the critical appraisal of studies on the basis on EBM principles, the explanation of EBM-relevant statistical outcome parameters (e.g., ''likelihood ratio'' for diagnostic and ''number needed to treat'' for interventional procedures), as well as the problems facing evidence-based radiology. Evidence-based evaluation of radiological procedures does not only address aspects of cost-effectiveness, but is also particularly helpful in identifying patient-specific usefulness. Therefore it should become an integral part of radiologist training. (orig.)

  4. The American Society for Clinical Pathology resident in-service examination: does resident performance provide insight into the effectiveness of clinical pathology education?

    Science.gov (United States)

    McKenna, Barbara J

    2007-06-01

    The resident in-service examination in pathology is an in-training exercise that is taken by virtually all pathology residents in the United States as well as by some participants in Canada, Ireland, and Lebanon. Although all of the anatomic pathology topics in the examination, with only one exception-forensic pathology, show significant improvement in scores over the 4 years of residency training, three areas of clinical pathology training (laboratory administration, clinical chemistry, and microbiology) show significantly lower improvement in performance over the years of residency training. By contrast, transfusion medicine, hematopathology and the special topics section of the examination all demonstrate improved performance by residents over time. While the reason behind these differences must remain speculative at this time, these findings suggest that measures to improve effectiveness in clinical pathology training might be suggested by examining the differences between residency training practices between higher and lower performing areas of clinical pathology.

    Pleomorphic adenoma occurs commonly in the major salivary glands but is uncommonly encountered in the breast. In both of these locations, the tumor is typically grossly circumscribed and has a “mixed” histological appearance, being composed of myoepithelial and epithelial components amid a myxochondroid matrix. Herein, we report a case of pleomorphic adenoma of the breast which was preoperatively thought to represent a fibroadenoma on clinical and radiological grounds. It is the rarity of the...

    Dopaminergic medication for motor symptoms in Parkinson's disease (PD) recently has been linked with impulse control disorders, including pathological gambling (PG), which affects up to 8% of patients. PG often is considered a behavioral addiction associated with disinhibition, risky decision...... decision-making. Overall, the findings are consistent with the hypothesis of medication-related PG in PD and underscore the importance of taking clinical variables, such as age and personality, into account when patients with PD are medicated, to reduce the risk of PG....

    Cerebellar disorders, also called cerebellar ataxias, comprise a large group of sporadic and genetic diseases. Their core clinical features include impaired control of coordination and gait, as well as cognitive/behavioral deficits usually not detectable by a standard neurologic examination and therefore often overlooked. Two forms of cognitive/behavioral syndromes are now well identified: (1) the cerebellar cognitive affective syndrome, which combines an impairment of executive functions, including planning and working memory, deficits in visuospatial skills, linguistic deficiencies such as agrammatism, and inappropriate behavior; and (2) the posterior fossa syndrome, a very acute form of cerebellar cognitive affective syndrome occurring essentially in children. Sporadic ataxias include stroke, toxic causes, immune ataxias, infectious/parainfectious ataxias, traumatic causes, neoplasias and paraneoplastic syndromes, endocrine disorders affecting the cerebellum, and the so-called "degenerative ataxias" (multiple system atrophy, and sporadic adult-onset ataxias). Genetic ataxias include mainly four groups of disorders: autosomal-recessive cerebellar ataxias, autosomal-dominant ataxias (spinocerebellar ataxias and episodic ataxias), mitochondrial disorders, and X-linked ataxias. In addition to biochemical studies and genetic tests, brain imaging techniques are a cornerstone for the diagnosis, clinicoanatomic correlations, and follow-up of cerebellar ataxias. Modern radiologic tools to assess cerebellar ataxias include: functional imaging studies, magnetic resonance spectroscopy, volumetric studies, and tractography. These complementary methods provide a multimodal appreciation of the whole long-range cerebellar network functioning, and allow the extraction of potential biomarkers for prognosis and rating level of recovery after treatment.

    Extramammary Paget's disease (EMPD) is a rare cutaneous neoplasm that is thought to represent intraepithelial adenocarcinoma developing in an area rich in apocrine glands. Magnetic resonance imaging (MRI) findings for this disease are not well established. We report three cases of pathologically confirmed EMPD in which MRI was performed before surgery. The lesions were widespread in the epidermis and the dermis. Lesions were sharply well enhanced on gadolinium-enhanced T1-weighted imaging and appeared hyperintense on diffusion-weighted imaging in all cases. Areas with enhancement in depth corresponded well with the pathological lesion. In addition, different malignant legions were found on the same images from MRI in two cases, indicating potential associations with other malignancies. We describe the MRI findings and their pathological correlation. MRI could be useful for preoperative evaluation of disease spread and detection of associated malignancies. (orig.)

    Background The paralimbic system, which is composed of three parts, is an important functional unit. Gliomas located in the region remain a challenge for clinical treatment. However, the dynamic change of gliomas in the area has not been well documented. The purpose of this study was to identify the growth tendency of gliomas located in the paralimbic system and to obtain some suggestions for clinical treatment. Methods Eleven cases of gliomas located in the paralimbic system were recruited in the study. All of them were proven by pathology. Analysis of the serial radiological examinations in each patient was performed from the initial to the final examination, taking into consideration the following items: initial tumor location, final location and the growth tendency. Results In the initial and final examinations the ratios of insula involvement were 64% and 100%, respectively. On the other hand, the ratios of gliomas located in two or more partS of paralimbic system increased from 64%to 100%during the dynamic examination. Conclusions Even though the paralimbic system is composed of three independent anatomical parts, gliomas tend to involve all three pans, especially the insula. Therapeutic plans should aim at the whole region of the system, even during the early stages of gliomas.

    Full Text Available Giant cell tumor of bone accounts for about 5% of all primary bone tumors in adults and is still one of the most obscure and intensively examined tumors of bone. This largely results from the lack of uniform clinical, radiographic, histological or morphological aspects that allow prediction of recurrence. Classified by the World Health Organization as “an aggressive, potentially malignant lesion”, the giant cell tumor of bone could give lung metastases, could undergo malignant degeneration or could have multicentric localization. It usually develops in long bones but can also occur in unusual locations. The common presenting symptom is increasing pain at the tumor site. Standard treatment ranges from curettage to wide resection, with reports of varying oncological and functional results. The recurrence rate is high during the first 2-3 years after surgery regardless of pre-operative tumor stage. Herein, we discuss the morphological, clinical, radiological, and therapeutic characteristics of this pathologic entity as well as its differential diagnosis. J Clin Exp Invest 2014; 5 (3: 475-485

    Tooth impaction is a pathological situation where a tooth fails to attain its normal functional position. Impacted third molars are commonly encountered in routine dental practice. The impaction rate is higher for third molars when compared with other teeth. The mandibular third molar impaction is said to be due to the inadequate space between the distal of the second mandibular molar and the anterior border of the ascending ramus of the mandible. Impacted teeth may remain asymptomatic or may be associated with various pathologies such as caries, pericoronitis, cysts, tumors, and also root resorption of the adjacent tooth. Even though various classifications exist in the literature, none of those address the combined clinical and radiologic assessment of the impacted third molar. Literature search using the advanced features of various databases such as PubMed, Scopus, Embase, Google Scholar, Directory of Open Access Journals and Cochrane electronic databases was carried out. Keywords like impaction, mandibular third molar, impacted mandibular third molar, complications, anatomy, inferior alveolar nerve injury, lingual nerve injury were used to search the databases. A total of 826 articles were screened, and 50 articles were included in the review which was obtained from 1980 to February 2015. In the present paper, the authors have proposed a classification based on clinical and radiological assessment of the impacted mandibular third molar. PMID:26229709

    Use of a special high molecular guar preparation in small bowel contrast studies results in a roentgenological detection of the villous architecture of the small intestine. A diffuse villous atrophy results in a loss of the normal granular pattern. Segmental loss of granular mucosal texture is found in chronic radiogenic enteritis. In active Crohn's disease a coarser diffusely distributed granular appearance of the mucous surface occurs in addition to the segmental inflammatory changes. A coarse granular mucosal pattern with only segmental involvement is seen in mild malabsorption syndrome in the upper jejunum. Radiological signs for an intestinal protein loss syndrome is a coarsened and weakly contrasted granular mucosal pattern in the lower ileum with moderate thickening of the jejunal folds and increased liquid content of the bowel.

  9. Radiological and clinical pattern of pulmonary Tuberculosis in selected TB clinics in Khartoum

    International Nuclear Information System (INIS)

    160 adult tuberculous patients were selected randomly from Al shaab and Abu Anja hospital, to (1) study the clino-radiological pattern of the disease, (2) to determine the percentage of radiologically-positive patients and (3) to study the frequency of the initial presenting symptoms and to correlate them with their x-ray findings. A flow-sheet was filled and proper clinical examination was conducted for each patient. Tuberclin test, 3 sputa examinations, ESR and chest x-ray were done for every patient. Three quarters of the patients were males in the young age group and most of the patients were of low socioeconomic status. The main presenting symptoms were productive cough, chest pain, dysnoea, fever, weight loss and malaise. Patients presented rather late, with a mean period of four months. 57 % of patients were sputum positive, 80% Tuberclin-positive and 98% had a high erythrocyte sedimentation rate (ESR). 15% of patients had radiological features of primary diseases of which hilar lymph-adenopathy was the commonest, while consolidation was the commonest parenchymal lesion. In post-primary disease fibrocavitory type was the commonest and together with exudative lesions constituted 98% of parenchymal lesions. 90% of patients had typical upper or middle zone infiltrates and 10% had lower lung field tuberculosis. 14% of patients had pleural effusion. 60% of patients had moderate disease extent in the chest, 30% far-advanced and 10% minimal lesions in their chest x-ray.(Author)

    2012-01-01

    Full Text Available Anti-Ro/SSA antibodies are among the most frequently detected autoantibodies against extractable nuclear antigens and have been associated with systemic lupus erythematosus (SLE and Sjögren's syndrome (SS. Although the presence of these autoantibodies is one of the criteria for the diagnosis and classification of SS, they are also sometimes seen in other systemic autoimmune diseases. In the last few decades, the knowledge of the prevalence of anti-Ro/SSA antibodies in various autoimmune diseases and symptoms has been expanded, and the clinical importance of these antibodies is increasing. Nonetheless, the pathological role of the antibodies is still poorly understood. In this paper, we summarize the milestones of the anti-Ro/SSA autoantibody system and provide new insights into the association between the autoantibodies and the pathogenesis of autoimmune diseases.

Percentage as summary measure to statically validate the results and Kappa index to determine diagnostic concordance were used. Women between 40-49 years with history of fibrocystic breast disease and palpable lesions, as well as lump in the right breast, upper outer quadrant and periphery of the breast, tumor greater than one centimeter in diameter and infiltrating ductal carcinoma in the stages III-b and IV prevailed in the case material.(author)

  12. Comprehensive Clinical Audits of Diagnostic Radiology Practices: A Tool for Quality Improvement. Quality Assurance Audit for Diagnostic Radiology Improvement and Learning (QUAADRIL)

    International Nuclear Information System (INIS)

    Interest in quality assurance processes and quality improvement in diagnostic radiology is being driven by a number of factors. These include the high cost and complexity of radiological equipment, acknowledgement of the possibility of increasing doses to patients, and the importance of radiological diagnosis to patient management within the health care environment. To acknowledge these interests, clinical audits have been introduced and, in Europe, mandated under a European Directive (Council Directive 97/47/EURATOM). Comprehensive clinical audits focus on clinical management and infrastructure, patient related and technical procedures, and education and research. This publication includes a structured set of standards appropriate for diagnostic radiology, an audit guide to their clinical review, and data collection sheets for the rapid production of reports in audit situations. It will be a useful guide for diagnostic radiology facilities wishing to improve their service to patients through timely diagnosis with minimal radiation dose.

  13. Ataxia-telangiectasia: some historic, clinical and pathologic observations.

    Although an isolated clinical case report was published in 1926 and another in 1941, ataxia-telangiectasia (A-T) was not established as a distinct entity until 1957, when it was first delineated clinicopathologically. Susceptibility to sinopulmonary infection was identified as the main cause of death and as the third major component of the syndrome; its heredofamilial nature was documented, and it was designated "ataxia-telangiectasia." In a later review of 101 published cases, lymphoreticular malignancy emerged as the second most frequent cause of death. Although the thymus was found to be absent in the first reported autopsy in 1957 and the serum IgA deficiency was first recorded in 1961, A-T was not established as an immunodeficiency disease until 1963. Thymic abnormality and dysgammaglobulinemia explain the 2 main causes of death, sinopulmonary and neoplastic, but the immunodeficiency is probably not the central defect. It does not appear to explain either of the 2 main clinical diagnostic keys, the ataxia and the telangiectasia, or any of the other seemingly unrealted multisystemic facets of this complex disorder. Some of our most provocative long-term clinical observations and recent pathologic findings in our series of 9 autopsies are discussed.

    Full Text Available Pleomorphic adenoma occurs commonly in the major salivary glands but is uncommonly encountered in the breast. In both of these locations, the tumor is typically grossly circumscribed and has a “mixed” histological appearance, being composed of myoepithelial and epithelial components amid a myxochondroid matrix. Herein, we report a case of pleomorphic adenoma of the breast which was preoperatively thought to represent a fibroadenoma on clinical and radiological grounds. It is the rarity of the tumor in the breast, rather than its histological appearance, that causes diagnostic difficulty.

    Acinar cystic transformation of the pancreas is also known as acinar cell cystadenoma (ACC), and this is an extremely rare benign lesion that was first described in April 2002. We report here on a case of a previously asymptomatic patient with pancreatic ACC and this was diagnosed by computed tomography (CT) and magnetic resonance imaging (MRI). To the best of our knowledge, there is no previous report concerning the CT or MRI features of ACC in the medical literature. We present here the CT, MRI and pathological findings of pancreatic ACC

  16. A clinical and radiological observation of shoulder arthrography

    International Nuclear Information System (INIS)

    The authors analyzed 23 cases of shoulder arthrography performed at Busan National University Hospital and Inje Medical College Paik Hospital for about 2.5 years from March 1981 to September 1983, both clinically and radiologically. The results obtained were as follows: 1. Of the 23 cases, 20 cases (87.0%) were male and 3 cases (13.0%) were female, and the most prevalent age group was second decade. 2. Right shoulder arthrography was performed in 16 cases (69.6%), and left in 7 cases (30.4%). 3. The number of cases which had had certain history of trauma was 13 (56.5%), and remainder of 10 cases (43.5%) had no history of trauma. 4. Frequent symptoms and signs were pain in shoulder region in 16 cases (69.6%) and limitation of motion in 14 cases (60.9%). 5. On plain film findings, 18 cases (78.3%) were normal, and 5 cases (21.7%) were abnormal. 6. On shoulder arthrographic findings, 16 cases (69.6%) were normal, and 7 cases (30.4%) were abnormal. Those abnormal cases were consisted of 2 cases (8.7%) of adhesive capsulitis, 2 cases (8.7%) of chronic shoulder dislocation, 1 case (4.3%) of rotator cuff tear, 1 case (4.3%) of loose bodies in joint cavity, and 1 case (4.3%) of rupture of biceps tendon sheath. 7. Among routine views of shoulder arthrography of normal cases, the external rotation view revealed axillary recess and biceps tendon more distincity, and the internal rotation view revealed subscapular bursa more clearly. In case of double contrast shoulder arthrography, the contour and thickness of the medial segment of the contrast coated humeral articular cartilage were well demonstrated in erect views, with air-fluid levels in axillary recess, biceps tendon sheath and subscapular bursa. 8. The 2 cases of adhesive capsulitis revealed small joint space, obliteration of the axillary recess and subscapular bursa, and failure to fill the bicipital sheath. 9. The 2 cases of capsular deformities by chronic shoulder dislocation demonstrated loss of normal concavity of

    Technical advances in magnetic resonance imaging (MRI), notably in high-resolution MRI, have opened up new diagnostic applications in male pelvic pathology. A major indication is the preoperative staging of prostate cancer, where MRI is more reliable than other imaging modalities in differentiating between localized and advanced disease. In monitoring local recurrence after radical prostatectomy MRI is also valuable in differentiating scar tissue from new growth. In benign prostate disease, MRI effectively displays the congenital cysts that may be associated with infertility. Other disease, however - notably benign prostatic hyperplasia - is generally an incidental finding. Ultrasound remains the imaging modality of choice for evaluation of pathologies of the penis, testis and scrotum, e. g. in differentiating malignant from benign scrotal masses or in diagnosing acute scrotum due to testicular torsion or rupture. In isolated cases, MRI is also a valuable diagnostic aid in conditions of these organs, e. g. in the preoperative localization of ectopic testes in cryptorchidism or if US findings are equivocal.

    The migration of imaging reports to electronic medical record systems holds great potential in terms of advancing radiology research and practice by leveraging the large volume of data continuously being updated, integrated, and shared. However, there are significant challenges as well, largely due to the heterogeneity of how these data are formatted. Indeed, although there is movement toward structured reporting in radiology (ie, hierarchically itemized reporting with use of standardized terminology), the majority of radiology reports remain unstructured and use free-form language. To effectively "mine" these large datasets for hypothesis testing, a robust strategy for extracting the necessary information is needed. Manual extraction of information is a time-consuming and often unmanageable task. "Intelligent" search engines that instead rely on natural language processing (NLP), a computer-based approach to analyzing free-form text or speech, can be used to automate this data mining task. The overall goal of NLP is to translate natural human language into a structured format (ie, a fixed collection of elements), each with a standardized set of choices for its value, that is easily manipulated by computer programs to (among other things) order into subcategories or query for the presence or absence of a finding. The authors review the fundamentals of NLP and describe various techniques that constitute NLP in radiology, along with some key applications. PMID:26761536

    In the last two decades, our knowledge about cancer genetics and cancer biology increased exponentially. Deep sequencing now allows rapid and cost-effective analysis of entire cancer genomes. Dysregulation of cell growth, cell survival, tissue homeostasis, and immune surveillance have been recognized as hallmarks of cancer. In parallel, diagnostic surgical pathology has been harmonized and consensus diagnostic criteria for cancer classification have been developed by initiatives of the World Health Organization, the International Agency for Research on Cancer, and the Union for International Cancer Control. Pharmaceutical companies developed novel drugs targeting specific molecules in signaling pathways, which has allowed the development of the concept of precision medicine. Now, we are facing a large number of clinical trials which bring together these advances and will explore efficacy of novel treatment regimens. Assessment of the efficacy of a new drug is often coupled with the simultaneous assessment of the capacity of tissue-based biomarkers to predict response of individual patients (companion diagnostics/precision medicine). Patients with histologically similar tumors might respond differently to the same drug. This review summarizes the diverse roles played by surgical pathologists involved in clinical trials, with a special focus on quality assurance of diagnostic, laboratory, and reporting standards.

    Classic (triphasic) renal angiomyolipoma (AML) is currently classified as a neoplasm of perivascular epithelioid cells. For diagnosis of AML, the use of thin-section non-contrast enhanced CT (NECT) improves diagnostic accuracy; however, identifying gross fat within a very small AML is challenging and often better performed with chemical-shift MRI. Although the presence of gross intra-tumoural fat is essentially diagnostic of AML; co-existing intra-tumoural fat and calcification may represent renal cell carcinoma (RCC). Differentiating AML from retroperitoneal sarcoma can be difficult when AML is large; the feeding vessel and claw signs are suggestive imaging findings. AML can haemorrhage, with intra-tumoural aneurysm size >5 mm a more specific predictor of future haemorrhage than tumor size >4 cm. Diagnosis of AML in the setting of acute haemorrhage is complex; comparison studies or follow-up imaging may be required. Not all AML contain gross fat and imaging features of AML without visible fat overlap with RCC; however, homogeneity, hyperdensity at NECT, low T2-weighted signal intensity and, microscopic fat are suggestive features. Patients with tuberous sclerosis often demonstrate a combination of classic and minimal fat AML, but are also at a slightly increased risk for RCC and should be imaged cautiously. Several rare pathological variants of AML exist including AML with epithelial cysts and epithelioid AML, which have distinct imaging characteristics. Classic AML, although benign, can be locally invasive and the rare epithelioid AML can be frankly malignant. The purpose of this review is to highlight the imaging manifestations of 10 uncommon and unusual variants of AML using pathological correlation.

    Full Text Available Pathologists and radiologists spend years acquiring and refining their medically essential visual skills, so it is of considerable interest to understand how this process actually unfolds and what image features and properties are critical for accurate diagnostic performance. Key insights into human behavioral tasks can often be obtained by using appropriate animal models. We report here that pigeons (Columba livia-which share many visual system properties with humans-can serve as promising surrogate observers of medical images, a capability not previously documented. The birds proved to have a remarkable ability to distinguish benign from malignant human breast histopathology after training with differential food reinforcement; even more importantly, the pigeons were able to generalize what they had learned when confronted with novel image sets. The birds' histological accuracy, like that of humans, was modestly affected by the presence or absence of color as well as by degrees of image compression, but these impacts could be ameliorated with further training. Turning to radiology, the birds proved to be similarly capable of detecting cancer-relevant microcalcifications on mammogram images. However, when given a different (and for humans quite difficult task-namely, classification of suspicious mammographic densities (masses-the pigeons proved to be capable only of image memorization and were unable to successfully generalize when shown novel examples. The birds' successes and difficulties suggest that pigeons are well-suited to help us better understand human medical image perception, and may also prove useful in performance assessment and development of medical imaging hardware, image processing, and image analysis tools.

    Full Text Available BACKGROUND Lung cancer is presently the most common malignant disease (13% of all cancers and the leading cause of cancer deaths (19% of all cancer deaths in the world in all age groups and in both sexes. It is the leading cause of cancer deaths in developed as well as in developing countries. OBJECTIVE The present study was conducted to study the various clinical and pathological presentations of bronchogenic carcinoma. MATERIALS AND METHODS A total of 82 patients with histologically proven bronchogenic carcinoma, hospitalized between 2012 and 2014 at a tertiary care centre, Pune, India, were analysed. RESULT Out of a total of 82 diagnosed cases, average age was 61 years, nearly 80.0% were males. Smoking was the risk factor in 63.41%. About 2% of female patients were smokers. Six (7.3% patients were <40 years of age at the time of diagnosis. Fiberoptic bronchoscopy (75.60% was found to be the most efficient diagnostic procedure. Histologically, adenocarcinoma, squamous cell carcinoma, non-small cell carcinoma and small cell carcinoma were seen in 57.31%, 24.39%, 9.75% and 6.09% cases, respectively. Distant metastases to organs like nodes, liver, adrenals and bones were present in 67%. CONCLUSION This study shows that adenocarcinoma is the most common type of lung cancer and clinical and radiological suspicion should lead to the prompt diagnosis and management.

    Hyperplastic polyps have traditionally been considered not to have malignant potential.New pathological classification of serrated polyps and recent discoveries about the serrated pathway of carcinogenesis have revolutionized the concepts and revitalized the research in this area.Until recently,it has been thought that most colorectal cancers arise from conventional adenomas via the traditional tumor suppressor pathway initiated by a mutation of the APC gene,but it has been found that this pathway accounts for only approximately 70%-80%of colorectal cancer (CRC) cases.The majority of the remaining colorectal cancer cases follow an alternative pathway leading to CpG island methylator phenotype carcinoma with BRAF mutation and with or without microsatellite instability.The mechanism of carcinomas arising from this alternative pathway seems to begin with an activating mutation of the BRAF oncogene.Serrated polyposis syndrome is a relatively rare condition characterized by multiple and/or large serrated polyps of the colon.Clinical characteristics,etiology and relationship of serrated polyposis syndrome to CRC have not been clarified yet.Patients with this syndrome show a high risk of CRC and both sporadic and hereditary cases have been described.Clinical criteria have been used for diagnosis and frequent colonoscopy surveillance should be performed in order to prevent colorectal cancer.In this review,we try to gather new insights into the molecular pathogenesis of serrated polyps in order to understand their possible clinical implications and to make an approach to the management of this syndrome.

  11. Assessment of HRCT findings of small bronchioloalveolar carcinoma by radiologic-pathologic correlation

    International Nuclear Information System (INIS)

    The purpose of this study is to assess the appearance of early stage bronchioloalveolar carcinoma (BAC) on HRCT in correlation with pathological findings. Fourteen cases of BAC were examined. Diameter of the lesion in all cases was less than 1.5 cm. Two cases of BAC appeared as inhomogeneous ground-glass opacity (GGO) in correlation with foci of BAC. Two cases of BAC appeared as homogeneous GGO on HRCT in correlation with hyperplasia of alveolar cells on mildly hyperplastic alveolar septa. One case of BAC had microscopical small alveolar collapse area, however the foci were too small to be recognized as elevated density area on HRCT. Eight cases of BAC appeared as elevated density areas in GGO. These elevated density areas were correlated with areas of diminishing intraalveolar air caused by fibrotic foci due to collapse of alveolar structure, high grade atypia of tumor cells with severe hyperplasia of alveolar septa, lymphoproliferation scattered in the lesion and cellular infiltration in alveoli. One case of BAC appeared as consolidative small nodule in correlation with mucinous BAC. (author)

    2016-08-01

    Full Text Available Objective: The purpose of this study was to perform radiological and clinical determination of the presence of psoriatic arthritis (PsA in patients with psoriasis and to evaluate associations with clinical findings. Materials and Methods: The medical files of 72 patients with psoriasis presenting to our clinic between years 2009-2014 with a pre-diagnosis of PsA were reviewed retrospectively. Hand, foot and sacroiliac joint radiograms were evaluated by a radiologist who was blinded to the patient’s clinical status and who is experienced on musculoskeletal radiology. Patients with psoriasis were divided into two groups according to the presence of arthritis which was determined based on radiographic findings or on Classification Criteria for Psoriatic Arthritis (CASPAR criteria. All patients’ demographic characteristics, length of disease, nail involvement, smoking-alcohol consumption were recorded. Results: The mean age of all patients was 47.24±14.61 years, and the mean duration of disease was 14.13±11.92 years. Smoking and alcohol consumptions were determined in 54.2% (n=39 and 23.6% (n=17 of the cases, respectively. Nail involvement was determined in 56.9% (n=41 of the cases. PsA was determined based on radiological findings in 58.3% (n=42 of the patients. The mean age and age at onset of disease were higher in PsA (+ patients than in radiologically non-PsA subjects. Based on clinical findings, PsA based on CASPAR criteria was determined in only 18.1% (n=13 of all patients. Conclusion: A higher level of PsA was determined using radiological evaluation in this study. The main cause of this condition is the existence of asymptomatic-subclinical patients. A detailed medical history should therefore be taken from patients, and good clinical evaluation is very important. Radiological and clinical evaluation should be performed together in the diagnosis.

    Nephropathia epidemica (NE) is a mild form of hemorrhagic fever with renal syndrome (HFRS). Its course varies from asymptomatic to fatal. The etiologic agent, Puumala virus, belongs to the Hantavirus genus of the Bunyaviridae family. Respiratory symptoms, from common cold to respiratory distress, occur in NE. Acute renal failure (ARF) is evident in over 90% of hospital-treated NE patients. In this review article, special attention is paid to radiological lung and renal involvement to investigate the occurrence and type of manifestations during the acute phase of infection and recovery.

    A mixed-methods evaluation was conducted to study learner attitudes and knowledge about clinical pathology across a curricular change that instituted a stand-alone clinical pathology course in place of content within a previously integrated pathology course structure. Groups of pre- and post-change students were assessed three times across the two semesters leading up to graduation. At each time, rank-ordered and open-ended response items probed attitudes, and multiple-choice items assessed knowledge. Data about student clinical pathology performance were also collected from clinical pathology instructors and supervising clinicians. Student rank-ordered items were evaluated by factor analysis; resulting factor-scale scores, multiple-choice scores, and rank responses from study cohorts were statistically assessed between groups and within each group over time. Intraclass correlations were calculated for the coding of student open-ended responses, and all coded responses were compared among groups. Analysis revealed that students in the revised curriculum had greater satisfaction with their training and greater confidence in data interpretation compared to students without exposure to an independent clinical pathology course. Although differences in knowledge of clinical pathology were not detected, it was also apparent that the independent clinical pathology course filled a student-perceived curricular need without raising criticisms related to diminished integration with anatomic pathology. Secondary study outcomes included formative feedback for course improvement, evidence of clerkship efficacy, and baseline data for further studies.

    Full Text Available BACKGROUND The presence of intra-peritoneal free cancer cells (IPFCC in adenocarcinoma stomach has been proven to be associated with grim prognosis and is staged as M1 disease in latest TNM staging. Major resections are not indicated in these patients that will add to the morbidity and increase the cost and duration of hospital stay and also delay the commencement of palliative chemotherapy. MATERIALS AND METHODS Study was conducted in a tertiary care apex institute in Kerala, India. 60 consecutive cases of clinically and radiologically proven non-metastatic adeno carcinoma stomach with tissue diagnosis, who were being planned for curative resection, were selected and subjected to preoperative laparoscopic peritoneal washing. 300 ml of normal saline was introduced to peritoneal cavity. Which was aspirated after irrigating all surfaces of the peritoneal cavity. Sample was centrifuged, stained with Papanicolaou stain and cytological analysis for IPFCC was done from the Department of Pathology. Statistical analysis was done using SPSS software version 18.1 and p-value <.05 was considered as significant. RESULTS AND DISCUSSION 31.6% (19 cases of the clinically and radiologically proven non-metastatic adenocarcinoma stomach were restaged as metastatic disease after laparoscopic peritoneal wash cytology analysis. Of them 14(23.3% of the sample had visible peritoneal metastasis found during laparoscopic inspection, but the remaining 5 cases did not have visible peritoneal metastasis but were positive for IPFCC which could be detected only after peritoneal wash cytology analysis and not by mere laparoscopic inspection, which accounts for 10.8% of those who were labeled as non-metastatic and curable even after preoperative diagnostic laparoscopy. CONCLUSION Preoperative laparoscopy and peritoneal wash cytology analysis is mandatory in clinically and radiologically proven non-metastatic carcinoma stomach, who are being planned for curative resection

    Irreversible electroporation (IRE) is a novel therapy that has shown to be a feasible and promising alternative to conventional ablative techniques when treating tumors near vital structures or blood vessels. The clinical efficacy of IRE has been evaluated using established imaging criteria. This study evaluates the histologic and imaging response of hepatic and pancreatic malignancies that were surgically resected after IRE. In total, 12 lesions ablated with IRE were included, including 3 pancreatic carcinomas, 5 primary tumors of the liver, and 4 metastatic tumors of the liver. The rate of complete response to IRE was 25% based on the histologic evaluation of the resected tumors. Although treatment-related vessel wall changes were noted in several cases in histologic findings, there was no evidence of vascular luminal narrowing or obliteration in any of the specimens. The imaging response to IRE before surgical resection usually resulted in underestimation of disease burden when compared with the histologic response seen on the resected specimens.

  20. Clinical and radiological study of the postoperative maxillary cyst

    International Nuclear Information System (INIS)

    Post operative maxillary cyst may arise after the surgical treatment for maxillary sinusitis with the symptoms of swelling, pain, and pus discharge in the buccal region. It is examined by Waters' view, panoramic view and other intraoral radiographs, but quite variable radiologically. Most of the cyst is seen round or ovoid shape radiolucency, destruction, expansion and thinning of oral and maxillofacial radiology, Seoul National University Hospital. We analyzed and obtained following results. 1. These cysts occurred more frequently in male than in female and the incidence is highest in the 4th and 5th decade.2. Initial radical operation of maxillary sinus were performed mainly between the age of 10 and 45 years, and about 60% of the patients were 15 to 25 years.3. Pain and swelling on buccal area, pus discharge, and toothache are most chief complaints seven cases were found at routine examination without symptoms. 4. Most of these cysts were unilocular with smooth and well-defined border. 5. The majority of the cysts occurred in the anterolateral wall of maxillary sinus. 6. Dental changes of the lesional area were loss of lamina dura and root resorption, but about 55% were not changed.

    Background Borderline gastrointestinal stromal tumors (GISTs) are intermediate tumors between benign and malignant variants; however, the clinical and pathological features of borderline GISTs remain poorly defined. This study aimed to characterize GISTs and to identify a set of borderline criteria for practical use.Methods Medical records and specimens of 840 patients from 12 hospitals were retrospectively examined. Totally 485 and 76 patients with any of the parameters predictive of either malignant or benign tumors were excluded. The Kaplan-Meier method was used to calculate disease-free survival and overall survival rates.Results Among the remaining 279 borderline GIST patients, 223 were followed up for 1 to 31.48 years. Two patients developed local recurrence, and both were cured by subsequent operations alone. The 5-year disease-free survival and overall survival rates were 99% and 100%, respectively. Morphologically, borderline GISTs typically exhibited moderate cellularity, and subsets of them also showed moderate atypia, low mitotic activities, or large tumor size. According to the National Institutes of Health (NIH) consensus criteria, the risk levels of the 279 GISTs were classified to be very low to high. However, the disease-free survival rates were not significantly different among these risk groups (P=0.681).Conclusions The proposed borderline GIST criteria in the current study may complement the existing NIH criteria,based primarily on tumor size and mitotic count, in the evaluation of the biological behaviors of GISTs. Since a subset of borderline GISTs with high risk level showed favorable outcome, the introduction of the borderline GIST system may avoid overdiagnosis and over therapy.

  2. Barriers and facilitators to adoption of soft copy interpretation from the user perspective: Lessons learned from filmless radiology for slideless pathology

    Full Text Available Background: Adoption of digital images for pathological specimens has been slower than adoption of digital images in radiology, despite a number of anticipated advantages for digital images in pathology. In this paper, we explore the factors that might explain this slower rate of adoption. Materials and Method: Semi-structured interviews on barriers and facilitators to the adoption of digital images were conducted with two radiologists, three pathologists, and one pathologist′s assistant. Results: Barriers and facilitators to adoption of digital images were reported in the areas of performance, workflow-efficiency, infrastructure, integration with other software, and exposure to digital images. The primary difference between the settings was that performance with the use of digital images as compared to the traditional method was perceived to be higher in radiology and lower in pathology. Additionally, exposure to digital images was higher in radiology than pathology, with some radiologists exclusively having been trained and/or practicing with digital images. The integration of digital images both improved and reduced efficiency in routine and non-routine workflow patterns in both settings, and was variable across the different organizations. A comparison of these findings with prior research on adoption of other health information technologies suggests that the barriers to adoption of digital images in pathology are relatively tractable. Conclusions: Improving performance using digital images in pathology would likely accelerate adoption of innovative technologies that are facilitated by the use of digital images, such as electronic imaging databases, electronic health records, double reading for challenging cases, and computer-aided diagnostic systems.

    Pulmonary hypertension (PH) has a broad differential and the radiological task is to define and characterize the pathophysiological background. The first part of the review is focused on the clinical categorization and specific features of the various groups of PH. Overall, PH is a rare disease and the clinical symptoms are non specific. Therefore, the disease is usually detected delayed. Each radiological technique, especially chest X-ray and CT, do show specific findings suggestive of PH, which will be discussed. Verification of the severity of PH is still a domain of invasive right heart catheterization. However, there are promising approaches using MRI to determine the pulmonary arterial pressure non-invasively. (orig.)

    Full Text Available OBJECTIVE: Cervical intraepithelial neoplasia grade 3 (CIN3, the immediate cervical cancer precursor, is a target of cervical cancer prevention. However, less than half of CIN3s will progress to cancer. Routine treatment of all CIN3s and the majority of CIN2s may lead to overtreatment of many lesions that would not progress. To improve our understanding of CIN3 natural history, we performed a detailed characterization of CIN3 heterogeneity in a large referral population in the US. METHODS: We examined 309 CIN3 cases in the SUCCEED, a large population-based study of women with abnormal cervical cancer screening results. Histology information for 12 individual loop electrosurgical excision procedure (LEEP segments was evaluated for each woman. We performed case-case comparisons of CIN3s to analyze determinants of heterogeneity and screening test performance. RESULTS: CIN3 cases varied substantially by size (1-10 LEEP segments and by presentation with concomitant CIN2 and CIN1. All grades of CINs were equally distributed over the cervical surface. In half of the women, CIN3 lesions were found as multiple distinct lesions on the cervix. Women with large and solitary CIN3 lesions were more likely to be older, have longer sexual activity span, and have fewer multiple high risk HPV infections. Screening frequency, but not HPV16 positivity, was an important predictor of CIN3 size. Large CIN3 lesions were also characterized by high-grade clinical test results. CONCLUSIONS: We demonstrate substantial heterogeneity in clinical and pathological presentation of CIN3 in a US population. Time since sexual debut and participation in screening were predictors of CIN3 size. We did not observe a preferential site of CIN3 on the cervical surface that could serve as a target for cervical biopsy. Cervical cancer screening procedures were more likely to detect larger CIN3s, suggesting that CIN3s detected by multiple independent diagnostic tests may represent cases

    Pulmonary disease is the most important cause of morbidity in preterm neonates, whose lungs are often physiologically and morphologically immature. Surfactant deficiency in immature lungs triggers a cascade of alveolar instability and collapse, capillary leak edema, and hyaline membrane formation. The term respiratory distress syndrome (RDS) has come to represent the clinical expression of surfactant deficiency and its nonspecific histologic counterpart, hyaline membrane disease. Historically, chest radiographs of infants with RDS predictably demonstrated decreased pulmonary expansion, symmetric generalized reticulogranular lung opacities, and air bronchograms. Refinements in perinatal medicine, including antenatal glucocorticoid administration, surfactant replacement therapy, and increasingly sophisticated ventilatory strategies have decreased the prevalence of RDS and air leak, altered familiar radiographic features, and lowered the threshold of potential viability to a gestational age of approximately 23 weeks. Alveolar paucity and pulmonary interstitial thickness in these profoundly premature neonates impair normal gas exchange and may necessitate prolonged mechanical ventilation, increasing the risk of lung injury. Bronchopulmonary dysplasia (BPD), alternatively termed chronic lung disease of infancy, is a disorder of lung injury and repair originally ascribed to positive-pressure mechanical ventilation and oxygen toxicity. Before the advent of surfactant replacement therapy, chest radiographs of infants with classic BPD demonstrated coarse reticular lung opacities, cystic lucencies, and markedly disordered lung aeration that reflected alternating regions of alveolar septal fibrosis and hyperinflated normal lung parenchyma. In the current era of surfactant replacement, BPD is increasingly a disorder of very low-birth-weight neonates with arrested alveolar and pulmonary vascular development, minimal alveolar septal fibrosis and inflammation, and more subtle

    Several studies have demonstrated the importance of environmental conditions in the radiology reporting environment, with many indicating that incorrect parameters could lead to error and misinterpretation. Literature is available with recommendations as to the levels that should be achieved in clinical practice, but evidence of adherence to these guidelines in radiology reporting environments is absent. This study audited the reporting environments of four teleradiologist and eight hospital based radiology reporting areas. This audit aimed to quantify adherence to guidelines and identify differences in the locations with respect to layout and design, monitor distance and angle as well as the ambient factors of the reporting environments. In line with international recommendations, an audit tool was designed to enquire in relation to the layout and design of reporting environments, monitor angle and distances used by radiologists when reporting, as well as the ambient factors such as noise, light and temperature. The review of conditions were carried out by the same independent auditor for consistency. The results obtained were compared against international standards and current research. Each radiology environment was given an overall compliance score to establish whether or not their environments were in line with recommended guidelines. Poor compliance to international recommendations and standards among radiology reporting environments was identified. Teleradiology reporting environments demonstrated greater compliance than hospital environments. The findings of this study identified a need for greater awareness of environmental and perceptual issues in the clinical setting. Further work involving a larger number of clinical centres is recommended.

    Between 1976 and 1982 336 patients with an age range from several days to 65 years, were treated by ventriculo-atrial or peritoneal shunt, because of internal hydrocephalus of different origins. Regular computerized tomographies demonstrated slit-ventricles in 36 patients. Twenty-eight patients were free of complaints. In 8 patients there were symptoms like nausea and vomiting. In 5 patients these complaints were explainable by other diseases. In only 3 patients were these signs caused by increased intracranial pressure because of ventricular-catheter obliteration. In these 3 cases an enlargement of the ventricles at the time of obliteration was seen. In our series slit-ventricles were seen only as a radiological phenomenon. There was no necessity for neurosurgical treatment at all.

    Despite remarkable progress in prevention and treatment, infectious diseases affecting the central nervous system remain an important source of morbidity and mortality, particularly in less-developed countries and in immunocompromised persons. Bacterial, fungal, and parasitic pathogens are derived from living organisms and affect the brain, spinal cord, or meninges. Infections due to these pathogens are associated with a variety of neuroimaging patterns that can be appreciated at magnetic resonance imaging in most cases. Bacterial infections, most often due to Streptococcus, Haemophilus, and Neisseria species, cause significant meningitis, whereas the less common cerebritis and subsequent abscess formation have well-documented progression, with increasingly prominent altered signal intensity and corresponding contrast enhancement. Atypical bacterial infections are characterized by the development of a granulomatous response, classically seen in tuberculosis, in which the tuberculoma is the most common parenchymal form of the disease; spirochetal and rickettsial diseases are less common. Fungal infections predominate in immunocompromised hosts and are caused by yeasts, molds, and dimorphic fungi. Cryptococcal meningitis is the most common fungal infection, whereas candidiasis is the most common nosocomial infection. Mucormycosis and aspergillosis are characterized by angioinvasiveness and are associated with high morbidity and mortality among immunocompromised patients. In terms of potential exposure in the worldwide population, parasitic infections, including neurocysticercosis, toxoplasmosis, echinococcosis, malaria, and schistosomiasis, are the greatest threat. Rare amebic infections are noteworthy for their extreme virulence and high mortality. The objective of this article is to highlight the characteristic neuroimaging manifestations of bacterial, fungal, and parasitic diseases, with emphasis on radiologic-pathologic correlation and historical perspectives

    During the conduct of in vivo toxicology studies, in-life, clinical pathology, and anatomic pathology parameters are collected and interpreted. These sets of parameters are evaluated in an integrative manner to determine the overall toxicity of a test article. For clinical pathology parameters, the inherent variability and physiologic factors affecting each analyte must be understood prior to interpretation. Changes in clinical pathology parameters that are considered to be test article-related are then assessed with respect to changes in the concurrent data sets such as clinical signs and anatomic pathology to determine the underlying pathophysiology. In this article, examples of hemolysis and hepatotoxicity are used to demonstrate the relationships among the various parameters and data sets. Whereas there was tight correlation of all data sets in the example of hemolysis in rats, the examples of altered enzymes and other biomarkers indicating liver injury and dysfunction were more often discordant with other data sets.

    To date, the pathogenesis of abdominal aortic aneurism (AAA) still remains unclear. As such, the aim of this study was to evaluate changes of the aortic structure during AAA. We analysed the microscopic frame of vessels sections, starting from the primum movens leading to abnormal dilatation. AAA samples were collected and processed through various staining methods (Verhoeff-Van Gieson, Masson Goldner, Sirius Red). Subsequently, the vessel morphology and collagenic web of the tunica media and adventitia were determined and the amount of type I and type III collagen was measured. We also applied immune-histochemistry markers for CD34 and PGP 9.5 in order to identify vascular and nerve structures in the aorta. Immune-positivity quantification was used to calculate the percentage of the stained area. We found increasing deposition of type I collagen and reduced type III collagen in both tunica media and adventitia of AAA. The total amount of vasa vasorum, marked with CD34, and nerva vasorum, marked with PGP 9.5, was also higher in AAA samples. Cardiovascular risk factors (blood pressure, dyslipidemia, cigarette smoking) and radiological data (maximum aneurism diameter, intra-luminal thrombus, aortic wall calcification) increased these changes. These results suggest that the tunica adventitia may have a central role in the pathogenesis of AAA as clearly there are major changes characterized by rooted inflammatory infiltration. The presence of immune components could explain these modifications within the framework of the aorta. PMID:26858185

    Full Text Available Objective: Adnexal masses are the most common reason for gynecologic surgery in adolescent patients. Early detection and adequate management of adnexal lesions are very important for saving lives and preserving fertility. In this study, we analyzed the clinical characteristics of 106 Turkish adolescent women who underwent surgery for adnexal masses. Methods: The study included 106 patients aged ≤20 years that underwent surgery for adnexal masses at our hospital between January 2008 and December 2013. Clinical profiles were retrospectively collected from the hospital medical records. The records were analyzed for demographic profiles, initial symptoms, preoperative radiologic findings, operative approach, surgical procedure, pathology findings, and the maximum diameter of the adnexal mass. Results: The age of the patients ranged from 12 to 20 years (median, 18.8 years. The most common initial symptom in these patients was abdominal pain (56.6%. Non-neoplastic ovarian lesions in the patients included 7 (6.6% corpora hemorrhagica, 10 (9.4% corpus luteal cysts, 4 (3.8% paratubal cysts, and 7 (6.6% simple cysts. Benign neoplastic tumors included 20 (18.9% mature cystic teratomas (i.e., dermoid tumors, 10 (9.4% serous cystadenomas, 1 (0.9% mucinous cystadenomas, and 7 (6.6% endometriomas. The most common surgical approach and procedure were laparoscopy (67.0% and cystectomy (60.4%, respectively. Conclusion: Laparoscopy can be performed in many adolescent patients and conservative, adnexal-sparing surgery should be encouraged for all patients. Ovarian-preserving techniques should be a priority when surgery is performed for benign masses in order to optimize future fertility potential. J Clin Exp Invest 2015; 6 (2: 96-101

  15. Multi-parametric MRI of rectal cancer – Do quantitative functional MR measurements correlate with radiologic and pathologic tumor stages?

    International Nuclear Information System (INIS)

    Purpose: The purpose of this study is two-fold. First, to evaluate, whether functional rectal MRI techniques can be analyzed in a reproducible manner by different readers and second, to assess whether different clinical and pathologic T and N stages can be differentiated by functional MRI measurements. Materials and methods: 54 patients (38 men, 16 female; mean age 63.2 ± 12.2 years) with pathologically proven rectal cancer were included in this retrospective IRB-approved study. All patients were referred for a multi-parametric MRI protocol on a 3 Tesla MR-system, consisting of a high-resolution, axial T2 TSE sequence, DWI and perfusion imaging (plasma flow –s PFTumor) prior to any treatment. Two experienced radiologists evaluated the MRI measurements, blinded to clinical data and outcome. Inter-reader correlation and the association of functional MRI parameters with c- and p-staging were analyzed. Results: The inter-reader correlation for lymph node (ρ 0.76–0.94; p < 0.0002) and primary tumor (ρ 0.78–0.92; p < 0.0001) apparent diffusion coefficient and plasma flow (PF) values was good to very good. PFTumor values decreased with cT stage with significant differences identified between cT2 and cT3 tumors (229 versus 107.6 ml/100 ml/min; p = 0.05). ADCTumor values did not differ significantly. No substantial discrepancies in lymph node ADCLn values or short axis diameter were found among cN1-3 stages, whereas PFLn values were distinct between cN1 versus cN2 stages (p = 0.03). In the patients without neoadjuvant RCT no statistically significant differences in the assessed functional parameters on the basis of pathologic stage were found. Conclusion: This study illustrates that ADC as well as MR perfusion values can be analyzed with good interobserver agreement in patients with rectal cancer. Moreover, MR perfusion parameters may allow accurate differentiation of tumor stages. Both findings suggest that functional MRI parameters may help to discriminate T and

    Bone metastases from carcinomas are epidemiologically rising because of the increased survival rate of oncologic patients, related to several factors such as improvement of primary and secondary screening, advancement of medical research and technology and the better understanding of mechanisms underlying bone metastases origination from primary tumor. Skeletal Related Events (SREs) can seriously affect quality of life in patients with metastatic disease. These events include the necessity of radiotherapy or bone surgery, malignant hypercalcemia, pathologic fractures and spinal cord compression. Among the SREs, pathologic fractures are the most disabling events and represent an emergency in these delicate patients. A pathologic fracture is defined as a fracture that occurs at the level of a pre-existing bone lesion (that is often a tumor), spontaneously or as the result of low-energy trauma (1). The pre-existence of the metastatic lesion in the bone, its evaluation and the assessment of progression can make these complications predictable and preventable. Pathologic fractures imply several severe consequences, including patient immobilization (in the case of fractures involving the lower limbs), loss of autonomy, anaemia, need of blood transfusion, discontinuation of medical therapies or radiotherapy and protracted hospitalization. Secondary effects of prolonged immobilization and loss of autonomy further lengthen this list of complications in patients who are already significantly limited in their activities. In the present paper, the authors present a review on the main aspects involved in bone metastastic disease: biology, quality of life, economic impact and survival. PMID:26652492

    A clinical trial is an experimental study to evaluate the efficacy and safety of a treatment or diagnostic technique in human beings. To ensure the methodological quality of a clinical trial and the validity of its results, various checklists have been elaborated to identify biases that could invalidate its conclusions. This article focuses on the points we need to consider in the critical evaluation of a clinical trial. We can usually find this information in the "materials and methods" and "results" sections of articles. Randomization, follow-up (or analysis of losses), blinding, and equivalence between groups (apart from the intervention itself) are some key aspects related to design. In the "results" section, we need to consider what measures of clinical efficacy were used (relative risk, odds ratio, or number needed to treat, among others) and the precision of the results (confidence intervals). Once we have confirmed that the clinical trial fulfills these criteria, we need to determine whether the results can be applied in our environment and whether the benefits obtained justify the risks and costs involved.

  2. Central pontine myelinolysis: clinical presentation and radiologic findings

    International Nuclear Information System (INIS)

    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.

    The purpose of this paper by the Regulatory Affairs Committee (RAC) of the American Society for Veterinary Clinical Pathology (ASVCP) is to review the current regulatory guidances (eg, guidelines) and published recommendations for best practices in veterinary toxicologic clinical pathology, particularly in the pharmaceutical and biotechnology industries, and to utilize the combined experience of ASVCP RAC to provide updated recommendations. Discussion points include (1) instrumentation, validation, and sample collection, (2) routine laboratory variables, (3) cytologic laboratory variables, (4) data interpretation and reporting (including peer review, reference intervals and statistics), and (5) roles and responsibilities of clinical pathologists and laboratory personnel. Revision and improvement of current practices should be in alignment with evolving regulatory guidance documents, new technology, and expanding understanding and utility of clinical pathology. These recommendations provide a contemporary guide for the refinement of veterinary toxicologic clinical pathology best practices.

    We have gathered 159 cases of facial paralysis from recent records in our hospital, including paralyses of central as well as peripheral origin, and presenting as the only symptom or as one of several major symptoms of the discomfort of each patient. Sixty-four percent of them were studied by CT scan and/or MR, confirming the existence of alterations in the pathway of nerve pair VII in 50% of the patients who underwent radiological study. Idiopathic facial paralysis was the most common type (42% of the total); while tumors and post-traumatic findings were the most constant radiological findings. From the analysis of the data, the importance of the clinical criteria for selection of the patients in the study and the protocol for radiological diagnosis employed can be deduced. (author)

    Pneumococcal meningitis is associated with substantial mortality and morbidity. We systematically assessed brain histopathology of 31 patients who died of pneumococcal meningitis from a nationwide study (median age 67 years; 21 (67 %) were male) using a pathology score including inflammation and vascular damage. Of the 27 patients with known time from the admission to death, 14 patients died within 7 days of admission and 13 after 7 days of admission. Eleven of 25 (44 %) patients had been treated with adjunctive dexamethasone therapy. Observed pathological processes were inflammation of medium-large arteries in 30 brains (97 %), cerebral haemorrhage in 24 (77 %), cerebritis in 24 (77 %), thrombosis in 21 (68 %), infarction in 19 (61 %) and ventriculitis in 19 (of 28 cases, 68 %). Inflammation of medium-large arteries led to obstruction of the vascular lumen in 14 (of 31 cases, 45 %). Vascular inflammation was associated with infarction and thrombosis of brain parenchymal vessels. Hippocampal dentate gyrus apoptosis between patients treated with and without dexamethasone was similar (p = 0.66); however, dexamethasone treated patients had higher total pathology score than non-dexamethasone treated patients (p = 0.003). Our study shows that vascular damage is key in the process of brain damage in pneumococcal meningitis. Data and material of this study will be made open-access for translational research in pneumococcal meningitis (MeninGene-Path). PMID:27001057

    Paraquat is a nonselective contact herbicide of great toxicological importance, being associated with high mortality rates, mainly due to respiratory failure. We report the case of a 22-year-old male admitted to the emergency room with a sore throat, dysphagia, hemoptysis, and retrosternal pain after the ingestion of 50 mL of a paraquat solution, four days prior to admission. Chest CT scans revealed pulmonary opacities, pneumomediastinum, pneumothorax, and subcutaneous emphysema. The patient was submitted to two cycles of immunosuppressive therapy with cyclophosphamide, methylprednisolone, and dexamethasone. The pulmonary gas exchange parameters gradually improved, and the patient was discharged four weeks later. The clinical and tomographic follow-up evaluations performed at four months after discharge showed that there had been further clinical improvement. We also present a brief review of the literature, as well as a discussion of the therapeutic algorithm for severe paraquat poisoning. (author)

    International Nuclear Information System (INIS)

    Paradoxical clinical deterioration of miliary tuberculosis, characterized by pulmonary and abdominal manifestations, is reported in a patient with the acquired immunodeficiency syndrome, after initiation of treatment with highly active antiretroviral therapy. Paradoxical reaction was attributed to partial restoration of cell-mediated immunity related to highly effective antiretroviral therapy. Because tuberculosis has a high prevalence in HIV patients and tuberculosis is often characterized by miliary spreading of disease in these patients, it is important to recognize this phenomenon.

    Sometimes curious foreign bodies placed in the proventriculus/ventriculus of companion birds are causes of single case diseases. Clinical signs include untypical symptoms such as distress, lameness, vomiting and diarrhoe. In cases of heavy metal intoxication, e.g. lead poisoning, CNS-disorders are found. Radiographs taken in a ventro-dorsal and a latero-lateral view show the presence of foreign bodies in suspicion. In most cases of foreign bodies in birds a surgical intervention (Gastrotomy) is indicated

    Full Text Available Respiratory diseases impose a tremendous health burden on society. As countries industrialize, rising pollution and changes in lifestyle have contributed to increased levels of respiratory disease. Chronic obstructive pulmonary disease (COPD refers to a group of disorders characterized by chronic airflow obstruction/limitation. The airway obstruction is persistent and largely irreversible. WHO defines COPD as encompassing two groups of lung diseases, chronic bronchitis and emphysema. The present universally accepted guidelines no longer divide COPD into chronic bronchitis or emphysema as there is not much difference with regard to treatment protocols. AIM: The present study is being undertaken to evaluate the clinical, radiological and pulmonary functions in patients of COPD. An attempt also has been made to classify patients of COPD into chronic bronchitis and emphysema. A total of 153 patients were screened and inclusion and exclusion criteria applied. Forty patients were evaluated clinically, radiologically and pulmonary functions including diffusion studies were done. They were phenotypically divided into emphysema predominant and chronic bronchitis predominant. Breathlessness as assessed by MMRC grade and pulmonary functions were equal in both the groups. There was no radiological and phenotypical correlation. CONCLUSION: There is no significant difference in the severity of airflow obstruction as measured by FEV1 between the two phenotypes of COPD (Fisher’s exact test, P>0.05. There is a significant overlapping of symptoms, radiological findings and pulmonary functions among the phenotypes of COPD. Hence it can be reasonably concluded that it is difficult to make a diagnosis of COPD phenotypes based on clinical, radiological, spirometry and DLCo parameters

    Full Text Available The present study aimed at assesssing – by clinical, histological and radiological investigations – the influence of some external factors on the pulp-dentin complex, and at providing a causal interpretation of the structural changes observed. Materials and methods. Clinical and radiological exams were performed on 65 old patients with ages between 60-75, and also on 40 young patients with ages between 20-35, presenting different dental-periodontal pathologies. The pulp-dentin complex was submitted to a morphopathological examination, to highlight the structural changes observed at microscopic level. Fragments of dental pulp were imersed in a 4% formaldehyde solution with phosphate buffer 0.1 M., pH 7.2, for 12 -14 hours, at a temperature of 4ºC, and 3-5 µm thick slices were prepared. The slices were coloured with hematoxylin-eosine (HE, by the trichromic technique – Masson. Photographies were taken with a Zeiss microscope, with Kodak 200 ASA. Results. Significant differences were observed, between the two groups of patients, as to the external factors that produce structural changes on pulp-dentin organ. In the group of young patients dental caries and coronal fillings prevailed, while the group of old patients was mostly associated with atrition and chronic marginal periodontitis. Out of the 40 young patients, 30 presented chronic dental caries (75%, while, among the 65 old patients, only 24 presented dental caries (36.9%. The percentages of coronary fillings between the two study groups were close, which could be considered as one of the causes producing changes in the pulp-dentin organ, following aggresive preparation of cavities, the action of materials used for the protection of pulp-dentin complex or of the materials used for coronry fillings. Conclusions. Dental pulp has a remarkable ability to counteract the action of harmful factors, producing a mineral barrier and stimulating the reparatory processes. Changes in the endodontic

    Full Text Available Objective: The aim of this study was to determine the prevalence of macroprolactin in patients with hyperprolactinemia in our region, and to determine the clinical and neuroradiological features of the affected individuals. Materials and Methods: We used the Roche Elecsys Prolactin assay (Prolactin II with polyethylene glycol precipitation to identify macroprolactin; recovery of ≤40% was considered to represent significant macroprolactinemia. Of 156 consecutive patients with hyperprolactinemia, macroprolactin was found in ten (6.4%. Clinical records of these patients were reviewed. Results: Of ten patients with macroprolactinemia, two males presented with infertility and two with decreased libido and erectile dysfunction. Females presented with menstrual dysfunction, with or without infertility. Pituitary adenomas were identified in two of seven patients who underwent neuroimaging. Dopamine agonists were prescribed to seven patients; their symptoms were not affected by this therapy. Conclusions: Macroprolactin is a cause of misdiagnosis and inappropriate treatment in patients with hyperprolactinemia. It is important to be aware of the extent to which the assay system used in the measurement of prolactin may detect macroprolactin, and to have a available validated method to confirm its presence. This will ensure appropriate management for patients with this benign condition. Turk Jem 2008; 12: 46-9

    For more than 100 years, examinations of pathology specimens have relied on the use of the light microscope. The technological progress of the last few years is enabling the digitizing of histologic specimen slides and application of the virtual microscope in diagnostics. Virtual microscopy will facilitate consultation possibilities, and digital image analysis serves to enhance the level of diagnostics. Organizing and monitoring clinicopathological meetings will become easier. Digital archive of histologic specimens and the virtual microscopy network are expected to benefit training and research as well, particularly what applies to the Finnish biobank network which is currently being established.

    Calibre persistent labial artery (CPLA) is defined as a primary arterial branch that penetrates into the submucosal tissue without division or decrease in diameter. It usually presents as an asymptomatic papule on the lower lip and can be easily misdiagnosed as a varix, haemangioma, venous lake, mucocele or fibroma. When it is ulcerated, squamous cell carcinoma is the most usual differential diagnosis. The most frequently used method to confirm the diagnosis of CPLA has been excisional biopsy, which carries the risk of profuse bleeding. Angiography, another invasive method, has also been used. Here, we report a case of a 20-year-old woman with a 5-year history of multiple CPLA lesions involving both upper and lower lips. In this case, the diagnosis was made clinically and confirmed by Doppler ultrasonography, which is a noninvasive and simple diagnostic tool. PMID:16716155

    Full Text Available Abstract Background Systematic reviews have shown that, although well prepared, the Consensus Guidelines have failed to change clinical practice. In the healthcare district of Castelnovo né Monti (Reggio Emilia, Italy, it became necessary for the GPs and Clinical Pathologists to work together to jointly define laboratory profiles. Methods Observational study with two cycles of retrospective audit on test request forms, in a primary care setting. Objectives of the study were to develop pathology-specific laboratory profiles and to increase the number of provisional diagnoses on laboratory test request forms. A Multiprofessional Multidisciplinary Inter-hospital Work Team developed pathology-specific laboratory profiles for more effective test requesting. After 8 training sessions that used a combined strategy with multifaceted interventions, the 23 General Practitioners (GPs in the trial district (Castelnovo nè Monti tested the profiles; the 21 GPs in the Puianello district were the control group; all GPs in both districts participated in the trial. All laboratory tests for both healthcare districts are performed at the Laboratory located in the trial district. A baseline and a 1-year audit were performed in both districts on the GPs’ request forms. Results Seven pathology-specific laboratory profiles for outpatients were developed. In the year after the first audit cycle: 1 the number of tests requested in the trial district was distinctly lower than that in the previous year, with a decrease of about 5% (p  Conclusions The first audit cycle showed a significant decrease in the number of tests ordered only in the trial district.

    BACKGROUND: As aging in elderly people, their brain tissue has degeneration and brain atrophy of different severity, and the volume of cranial cavity is relatively enlarged, it has greater compensatory ability to the space occupying lesion, and it is difficult to detect the meningioma because it grows to expand slowly, the tumor locates in non-functional region, and there are atypical symptoms and deficiency of localization signs.OBJECTIVE: To investigate the clinicopathologic features of senile meningiomas.DESIGN: A retrospective analysis.SETTING: Affiliated Hospital of Hebei University.PARTICIPANTS: Forty-nine elderly patients with meningioma were selected from the Department of Neurosurgery, Affiliated Hospital of Hebei University from May 1999 to March 2005, including 15 males and 34 females, 60 - 74 years of age, and they were all diagnosed by CT and MRI.METHODS: The sites of tumors were identified by CT and MRI examinations in all the patients. The tumors were partially or totally resected according to their own conditions. The types of the resected tumor were pathologically observed. The conditions of postoperative recovery were observed after 1, 3 and 6 months, and without new neurological dysfunction or complication was considered as good outcome.MAIN OUTCOME MEASURES: ① Sites and pathological types of the tumor; ② Postoperative outcomes and complications.RESULTS: All the 49 patients were involved in the analysis of results. ① The tumors had wide distributions with a main location in brain convexity. Among the 49 cases of meningioma, there were 25 cases of fibrocystic type, 12 cases of meningothelial type, 6 cases of psammomatous type, 4 cases of angiomatous type and 2 cases of microcystic type. ② Among the 49 patients, 35 had good outcome, 8 had self-care ability, 4 required care by others, 2 (4.1%) died postoperatively. No long-term complication related to the operation was observed during the follow-up postoperatively.CONCLUSION: Meningioma has

    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.

    Posterior reversible encephalopathy syndrome (PRES) is an obstetric emergency frequently occurring in a pregnant or puerperal woman, manifested with an acute headache, consciousness impairment, seizures, and visual deficits and is associated with white matter changes predominantly affecting the posterior parietal and occipital lobes of the brain. Apart from the above-described typical location of the changes, the most common atypical location involves the brain stem and basal ganglia. Since magnetic resonance imaging (MRI) is more sensitive and specific imaging technique compared to computerized tomography, establishing the diagnosis and follow-up in patients with PRES is based mainly on MRI findings. It is particularly important not to exclude PRES as a possible diagnosis when we have the appropriate clinical presentation accompanied by the atypical radiological findings, since this clinical-radiological syndrome can often be manifested with an atypical MRI image.

Since magnetic resonance imaging (MRI is more sensitive and specific imaging technique compared to computerized tomography, establishing the diagnosis and follow-up in patients with PRES is based mainly on MRI findings. It is particularly important not to exclude PRES as a possible diagnosis when we have the appropriate clinical presentation accompanied by the atypical radiological findings, since this clinical-radiological syndrome can often be manifested with an atypical MRI image.

    The Society of Toxicologic Pathology formed a working group in collaboration with the American Society for Veterinary Clinical Pathology to provide recommendations for the appropriate inclusion of clinical pathology evaluation in recovery arms of nonclinical toxicity studies but not on when to perform recovery studies. Evaluation of the recovery of clinical pathology findings is not required routinely but provides useful information on risk assessment in nonclinical toxicity studies and is recommended when the ability of the organ to recover is uncertain. The study design generally requires inclusion of concurrent controls to separate procedure-related changes from test article-related changes, but return of clinical pathology values toward baseline may be sufficient in some cases. Evaluation of either a select or full panel of standard hematology, coagulation, and serum and urine chemistry biomarkers can be scientifically justified. It is also acceptable to redesignate dosing phase animals to the recovery phase or vice versa to optimize data interpretation. Assessment of delayed toxicity during the recovery phase is not required but may be appropriate in development programs with unique concerns. Evaluation of the recovery of clinical pathology data for vaccine development is required and, for efficacy markers, is recommended if it furthers pharmacologic understanding.

    Aim: To evaluate the radiological and clinical findings in patients with pulmonary aspergillosis after solid organ transplantation. Materials and methods: This study included 13 consecutive patients (five liver, four kidney, and four heart transplant; 10 male and three female; median age 54 years; range 13-63 years) with histologically confirmed pulmonary aspergillosis after solid organ transplantation at a tertiary referral hospital. Chest radiographs and computed tomography (CT) examinations performed for diagnosis were available in all patients. Radiological findings, such as lesion characteristics, location, and associated findings, were assessed retrospectively by two radiologists. The changes in radiological findings and clinical response after treatment were also assessed. Clinical findings, such as time of onset, initial symptoms, clinical course, and laboratory findings, were reviewed. Results: The most common radiographic and CT findings were pulmonary nodules or masses (n = 12). The number of nodules or masses was less than 10 in eight patients. Associated findings were surrounding ground-glass opacity (n = 4), central low density (n = 8), central air cavity (n = 5), and air bronchogram (n = 3). Follow-up radiographs and/or CT after treatment showed improvement in eight patients, persistence in two, and deterioration in three. The onset time of pulmonary aspergillosis was a median of 32 days (range 15-165 days). The most common symptom at diagnosis was fever (n = 6). Ten of 13 patients did not have leucopaenia. There were two aspergillosis-associated deaths during the follow-up period. Conclusion: The most common radiological finding of pulmonary aspergillosis after solid organ transplantation is multiple nodules or masses, which commonly appear within 1 month following transplantation.

    Pathology as a basic science discipline traditionally is a component of the preclinical medical school curriculum. While there have been regional and nationwide surveys reporting on the curricular organization and instructional formats of preclinical pathology instruction, the extent of required pathology integration into the clinical medical school curriculum, particularly as it relates to practical issues of patient management, has not been studied. A survey soliciting information about required pathology programs in the clinical years was distributed to the members of the Undergraduate Medical Educators Section of the Association of Pathology Chairs (APC). A literature search of such programs was also performed. Thirty-seven respondents representing 30 medical schools (21% of the 140 Liaison Committee on Medical Education-accredited medical schools in the APC) described a total of 16 required pathology programs in the clinical years. An additional 10 programs were identified in the literature. Advantages of required pathology activities in the clinical years include educating medical students in effective utilization of anatomic and clinical pathology for patient care and exposing them to the practice of pathology. Reported challenges have been competition for curricular time in the clinical years, attitudinal resistance by clerkship directors, failure to recognize pathology as a clinical discipline, and insufficient number of faculty in pathology departments. By survey sample and literature review, there has been relatively little progress in the integration of required pathology exposure into the clinical years. Development of practice-related pathology competencies may facilitate introduction of such curricular programs in the future.

    Full Text Available This study was to define preoperative predictors from radiologic findings for the pathologic risk groups based on long-term surgical outcomes, in the aim to help guide individualized patient management.We retrospectively reviewed 321 consecutive patients with clinical stage IA lung adenocarcinoma with ground glass component on computed tomography (CT scanning. Pathologic diagnosis for resection specimens was based on the 2011 IASLC/ATS/ERS classification of lung adenocarcinoma. Patients were classified into different pathologic risk grading groups based on their lymph node status, local regional recurrence and overall survival. Radiologic characteristics of the pulmonary nodules were re-evaluated by reconstructed three-dimension CT (3D-CT. Univariate and multivariate analysis identifies independent radiologic predictors from tumor diameter, total volume (TV, average CT value (AVG, and solid-to-tumor (S/T ratio. Receiver operating characteristic curves (ROC studies were carried out to determine the cutoff value(s for the predictor(s. Univariate cox regression model was used to determine the clinical significance of the above findings.A total of 321 patients with clinical stage IA lung adenocarcinoma with ground glass components were included in our study. Patients were classified into two pathologic low- and high- risk groups based on their distinguished surgical outcomes. A total of 134 patients fell into the low-risk group. Univariate and multivariate analyses identified AVG (HR: 32.210, 95% CI: 3.020-79.689, P<0.001 and S/T ratio (HR: 12.212, 95% CI: 5.441-27.408, P<0.001 as independent predictors for pathologic risk grading.

    Objective: To investigate the clinical potential of diffusion-weighted imaging (DWI) in assessing renal pathology of chronic kidney disease (CKD). Methods: Seventy-one CKD patients and twelve healthy volunteers were examined using DWI with prospective acquisition correction. Renal biopsy specimens from the CKD patients were scored based on the severity of renal pathology and to confirm pathology type. CKD patients were divided into three groups according to pathology scores: mild, moderate, or severe. The association between renal apparent diffusion coefficient (ADC) values and pathology scores was investigated using Pearson's correlation and single factor analysis of variance. Multiple linear regression analysis was performed to explore associations between renal ADC values and pathology score, glomerular filtration rate, serum creatinine, and age. The Kruskal–Wallis H test was conducted to compare ADC values and pathology type. Results: Renal ADC values correlated negatively with pathology scores (r = −0.633, P < 0.001). The ADC values among the four groups (mild, moderate, severe impairment, and controls) were significantly different (F = 19.512, P < 0.001). However, when patients were stratified by pathology type, no significant differences were found in ADC values among these groups (χ{sup 2} = 9.929, P = 0.270). Further multiple linear regression analysis showed that only the pathology score and ADC values were related (t = −4.586, P = 0.000). Conclusions: DWI has clinical potential in assessing the severity of renal pathology in CKD and shows promise as a non-invasive and effective technique to guide therapy and follow-up.

    The aim of the study was to characterize the clinical and radiological spectrum of posterior reversible encephalopathy syndrome (PRES) in a large cohort. The radiological report data bases of the authors' university hospitals were searched for patients with PRES. Various imaging features at onset of symptoms and on follow-up as well as clinical and paraclinical data were tabulated in those patients fulfilling the criteria for PRES. Exploratory univariate analyses were performed. A total of 96 patients with PRES were included into the study. Wide differences in lesion location, diffusivity, distribution pattern, edema severity, hemorrhage, underlying diseases, symptoms, mean arterial pressure (MAP) and coagulation status were encountered. Hemorrhage occurred significantly more frequently in patients with altered coagulation state and was significantly associated with higher edema grades and with the presence of cytotoxic edema. There was a significant difference in MAP between toxic associations with higher MAP in infection, eclampsy and autoimmune disorders, while lower MAP was found in chemotherapy and immunsupression. In 82% of patients complete or near complete resolution of edema was noted during follow-up. Higher MAP levels were associated with incomplete edema resolution. In 43% of patients residual lesions were seen with a relatively even distribution between focal gliosis, infarction, posthemorrhagic residua, atrophy and laminar necrosis. PRES in this large hospital-based retrospective study comprises a wide radiological and clinical spectrum. Residual lesions were encountered more frequently than commonly expected. Our results point towards a differential contribution of high blood pressure to the course of PRES in different underlying etiologies.

    Heading AbstractBackground. Double aortic arch (DAA) is a congenital vascular anomaly that causes tracheal and oesophageal compression. It requires surgical intervention in patients with severe symptoms.Objective. To evaluate the clinical, radiological and functional follow-up after surgical relief of the compression.Materials and methods. Ten children (seven boys) with DAA were operated on at a mean age of 1.3 years (range 0.2-7.5). At a mean age of 10.1 years (range 5-18 years), a follow-up study was performed that included clinical, radiological and functional parameters.Results. Seven children reported only mild respiratory symptoms and some trouble with swallowing. Preoperative fluoroscopy with spot images showed the mean tracheal diameter at the level of stenosis to be 37{+-}23% of the maximal diameter. At the time of follow-up, this was 70{+-}13%. The mean of the oesophageal diameter was 39{+-}20% preoperatively and 47{+-}16% postoperatively. Maximal expiratory flow volume (MEFV) curves of seven children showed typical characteristics of intrathoracic upper airway obstruction. Mean peak expiratory flow was significantly reduced (77{+-}10% of predicted, P<0.0001). Bronchial hyper-reactivity, tested by methacholine challenge, was found in two patients.Conclusions. There was marked relief of clinical symptoms after surgical decompression of DAA in all patients. In spite of this, radiological narrowing of trachea and oesophagus persisted and lung function results were abnormal at long-term follow-up. (orig.)

    The authors studied 10 male patients with pneumoconiosis who were seen at Asahi Rosai Hospital and received a clinical diagnosis of chronic necrotizing pulmonary aspergillosis (CNPA) during a 15-year period, and detailed the long-term clinical and radiologic courses of four cases. Their occupational histories included pottery making and coal mining. Chest radiographic findings by the International Labor Organization profusion grading system were greater than category 2. All patients were symptomatic, with a productive cough, haemoptysis, and dyspnea. Serum findings were positive for the aspergillosis antibody in seven patients. The radiologic findings consisted of parenchymal infiltrates and cavities mostly containing mycetoma, which generally involved the upper lobes. The disease progressed slowly; in one patient, broad destruction of the lung was observed after > 10 years without antifungal administration. Most of the patients experienced clinical and radiologic improvement after receiving antifungal therapy, by oral, inhaled, or intracavitary administration. It was concluded that chronic persistent or progressive upper-lobe infiltrates and cavities in patients with pneumoconiosis should raise the possibility of CNPA. Early diagnosis and initiation of effective therapy are recommended to achieve a better outcome.

  5. Comparison of clinical and radiological findings in patients with retrosternal and cervical goiters

    International Nuclear Information System (INIS)

    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)

    Nine cases presented with a calcifying odontogenic cyst to the Dental Hospital of the College of Dentistry, Yonsei University, from January 1987 to September June, 1996, Clinical or histopathological findings were observed according to each radiologic criteria. The results obtained are as follows:1. The male to female ratio was 2 : 1 with a mean age of 25 years. 2. The radiographic appearances of nine caes were well-defined radiolucent lesions in which eight cases were shown until ocular lesions and only one lesion was seen multilocular lesion. 3. Radiologically, three of nine cases were pure radiolucent lesion and others, six cases were radiolucent contained a variable amount of radiopaque material. 4. Histologically, two cases were classified simple cyst, five were cyst associated odontoma, two were neoplastic type. 5. Histological findings according to the radiological classification, two of three radiolucent lesions were simple cys ts; another was a cyst associated with odontoma. While, four of six radiologic mixed lesions turned out to be a cyst associated with odontoma, two was the neoplastic type.

    generalized and pulsating, and often resolve with recumbency. Other clinical features may include nausea or emesis, diplopia, neck pain, disturbance in hearing, vertigo, photophobia, and visual deficits. CSF pressures have reportedly been low, normal, or even high. CSF examination may be normal, or may reveal xanthocromia, lymphocytic pleocytosis, or increased protein possibly secondary to dural venous engorgement. With few exceptions, intracranial MR imaging of intracranial hypotension reveals diffuse pachymeningeal enhancement. Subdural fluid collections and brain descent, as measured by inferior displacement of the iter relative to the incisural line, may also be seen. Pachymeningeal enhancement is characteristically thick, smooth, and uninterrupted . The enhancement is thought to result from accumulation of gadolinium-based contrast material in engorged dural veins and in the interstitium of the dura . Mokri et al reported subdural fluid collections that were mostly bilateral and without mass effect in 69% of patients with intracranial hypotension. The authors also described imaging evidence of brain or brain-stem descent in 62% of patients in their series. Ventricular size in subjects with intracranial hypotension is usually small (1, but can reverse after treatment of the CSF leakage. In the relatively few reports in the literature of spinal imaging findings of intracranial hypotension, MR images showed extradural fluid collections and pachymeningeal enhancement (1, 4–6. MR images may also depict the site of CSF leakage in the spine (1. Herein, we described a case of intracranial hypotension with symmetric bulky epidural enhancement seen along the anterolateral borders of the cervical spine. This enhancement was compatible with engorged epidural venous structures based on their characteristic location in the anterolateral spinal canal and sparing of the midline. Renowden et al (6 described a single case of intracranial hypotension with epidural venous engorgement in

    The International Atomic Energy Agency (IAEA) has a mandate to assist member states in areas of human health and particularly in the use of radiation for diagnosis and treatment. Clinical audit is seen as an essential tool to assist in assuring the quality of radiation medicine, particularly in the instance of multidisciplinary audit of diagnostic radiology. Consequently, an external clinical audit programme has been developed by the IAEA to examine the structure and processes existent at a clinical site, with the basic objectives of: (1) improvement in the quality of patient care; (2) promotion of the effective use of resources; (3) enhancement of the provision and organisation of clinical services; (4) further professional education and training. These objectives apply in four general areas of service delivery, namely quality management and infrastructure, patient procedures, technical procedures and education, training and research. In the IAEA approach, the audit process is initiated by a request from the centre seeking the audit. A three-member team, comprising a radiologist, medical physicist and radiographer, subsequently undertakes a 5-d audit visit to the clinical site to perform the audit and write the formal audit report. Preparation for the audit visit is crucial and involves the local clinical centre completing a form, which provides the audit team with information on the clinical centre. While all main aspects of clinical structure and process are examined, particular attention is paid to radiation-related activities as described in the relevant documents such as the IAEA Basic Safety Standards, the Code of Practice for Dosimetry in Diagnostic Radiology and related equipment and quality assurance documentation. It should be stressed, however, that the clinical audit does not have any regulatory function.

    Full Text Available &lt;B&gt;Purpose:&lt;/B&gt; Mucopolysaccharidosis IVA (MPS IVA; Morquio A syndrome is rare lysosomal storage disorder caused by &lt;I&gt;N&lt;/I&gt;-acetylgalactosamine- 6-sulfatase (GALNS deficiency. Only a few MPS IVA cases have been reported in the Korean literature; there is a paucity of research about clinical or radiologic findings for this disorder. Therefore, we studied clinical findings, radiological features, and genetic data of Korean MPS IVA patients for determining factors that may allow early diagnosis and that may thus improve the patients’ quality of life. &lt;B&gt;Method:&lt;/B&gt; MPS IVA was confirmed via assay for enzymatic activity of leukocytes in 10 patients. The &lt;I&gt;GALNS&lt;/I&gt; gene was analyzed. Patients’ charts were retrospectively reviewed for obtaining clinical features and evaluated for radiological skeletal surveys, echocardiography, pulmonary function test, and ophthalmologic test results. &lt;B&gt;Result:&lt;/B&gt; Nine patients had severe clinical phenotype, and 1 had an intermediate phenotype, on the basis of clinical phenotype criteria. Radiologic findings indicated skeletal abnormalities in all patients, especially in the hips and extremities. Eight patients had an odontoid hypoplasia, and 1 showed mild atlantoaxial subluxation and cord myelopathy. Genetic analysis indicated 10 different &lt;I&gt;GALNS&lt;/I&gt; mutations. Two mutations, c.451C&gt;A and c.1000C&gt;T, account for 37.5% (6/16 and 25% (4/16 of all mutations in this samples, respectively. &lt;B&gt;Conclusion:&lt;/B&gt; An understanding of the clinical and radiological features involved in MPS IVA may allow early diagnosis of MPS IVA. Adequate evaluations and therapy in the early stages may improve the quality of life of patients suffering from skeletal abnormalities and may reduce life-threatening effects of

    Full Text Available Background: Aim of current study was to determine the clinical characteristics, radiological, laboratory features and anti-tubercular drug sensitivity in new smear positive (category I pulmonary tuberculosis cases in a tertiary care dedicated TB OPD, Delhi. Methods: The study was a cross-sectional observational study and consists of 100 cases of new smear positive pulmonary tuberculosis cases (category I irrespective of age and sex. The sputum were collected, stained with Ziehl-Nielsen (Z-N staining and ultimately inoculated on Lowenstein-Jensen (L-J media for six weeks. All sputum smear positive cases were subjected to culture and drug-susceptibility testing by 1% proportion method on Lowenstein-Jensen (LJ medium. The Drug-Susceptibility Testing (DST for isoniazid (INH, rifampicin (R-cin, ethambutol (EMB and streptomycin (SM were performed. Results: The age and sex distribution of 100 patients showed that majority of the patients (79% belonged to 2nd, 3rd and 4th decades and 60 % were males and 40% were female with male to female ratio 3:2 respectively. Cough (83%, fever (77% and weight loss (76% were the most common presenting clinical features. The chest X-ray of 100 smear positive patients showed that 53% of patients had evidence of 35% unilateral and 18% bilateral consolidation and 46% had cavitary lesions on chest X-ray (PA view with 37% and 9% of patients having unilateral and bilateral cavities respectively. Of these 82 culture positives, 56.1% (n=46 were susceptible to all first-line anti-tubercular drugs, while 43.9% (n=36 were resistant to mostly one or other anti-tubercular drugs (INH, R-cin, SM or EMB. Conclusion: We stressed the importance of early diagnosis of new cases by clinico-pathological features, identifying of drug resistance trends in anti-tubercular treatment na and iuml;ve patients, in order to assess the efficacy of current interventions.

    AstraZeneca ran a bespoke study to generate age-matched clinical pathology and histopathology data from a cohort of Beagle dogs aged between 25 and 37 months to support the use of these older animals in routine preclinical toxicology studies. As the upper age range of Beagle dogs routinely used in toxicology studies does not normally exceed 24 months, there is an absence of appropriate age-matched historical control data. The generation of such data was crucial to understand whether age-related differences in spontaneous findings might confound the interpretation of toxicology study data. While the majority of the histopathology findings in all the older dogs occurred at a similar prevalence as those expected in young adult dogs (<24 months), a number of differences were observed in the thymus (involution), bone marrow (increased adiposity), testes (degenerative changes), and lung (fibrosis, pigment and alveolar hyperplasia) that could be misinterpreted as a test article effect. Minor differences in some clinical pathology values (hemoglobin, alkaline phosphatase, absolute reticulocytes) were of a small magnitude and considered unlikely to affect the interpretation of study data.

    A wide variety of medical imaging techniques pervade modern medicine, and the changing portability and performance of tools like ultrasound imaging have brought these medical imaging techniques into the everyday practice of many specialties outside of radiology. However, proper interpretation of ultrasonographic and computed tomographic images requires the practitioner to not only hone certain technical skills, but to command an excellent knowledge of sectional anatomy and an understanding of the pathophysiology of the examined areas as well. Yet throughout many medical curricula there is often a large gap between traditional anatomy coursework and clinical training in imaging techniques. The authors present a radiological anatomy course developed to teach sectional anatomy with particular emphasis on ultrasonography and computed tomography, while incorporating elements of medical simulation. To assess students' overall opinions about the course and to examine its impact on their self-perceived improvement in their knowledge of radiological anatomy, anonymous evaluation questionnaires were provided to the students. The questionnaires were prepared using standard survey methods. A five-point Likert scale was applied to evaluate agreement with statements regarding the learning experience. The majority of students considered the course very useful and beneficial in terms of improving three-dimensional and cross-sectional knowledge of anatomy, as well as for developing practical skills in ultrasonography and computed tomography. The authors found that a small-group, hands-on teaching model in radiological anatomy was perceived as useful both by the students and the clinical teachers involved in their clinical education. In addition, the model was introduced using relatively few resources and only two faculty members. Anat Sci Educ 9: 295-303. © 2015 American Association of Anatomists. PMID:26599321

    Efforts to develop Picture Archiving and Communications Systems (PACS) for the last ten years have concentrated mainly on developing systems for primary interpretation of digital radiological images. Much less attention has been paid to the clinical aspects of the radiology process. Clinical radiology services are an important component of the overall care delivery process, providing information and consultation services to referring physicians, the customers of radiology, in a timely fashion to aid in care decisions. Information management systems (IMS) are playing an increasingly central role in the care delivery process. No suitable commercial PACS or IMS products were available that could effectively provide for the requirements of the clinicians. We endeavored to fill this void at our institution by developing a system to deliver images and text reports electronically on-demand to the referring physicians. This system has evolved substantially since initial deployment eight years ago. As new technologies become available they are evaluated and integrated as appropriate to improve system performance and manageability. Not surprisingly, the internet and World Wide Web (WWW) technology has had the greatest impact on system design in recent years. Additional features have been added over time to provide services for teleradiology, teaching, and research needs. We also discovered that these value-added services give us a competitive edge in attracting new business to our department. Commercial web-based products are now becoming available which do a satisfactory job of providing many of these clinical services. These products are evaluated for integration into our system as they mature. The result is a system that impacts positively on patient care.

    We describe the clinical, physiological and pathological features of 23 subjects with early stage idiopathic pulmonary fibrosis. Thirteen subjects who had no symptoms had been fortuitously recruited by a routine chest radiograph, whereas the 10 other subjects complained of dyspnea. Twenty-one subjects showed only light to moderate extent of abnormalities on the chest radiograph. Fourteen subjects had a reduced vital capacity whereas 16 and 17 showed a reduced pulmonary compliance and an increase in lung elastic recoil, respectively. Transfer factor was significantly reduced in 18 subjects. Evidence for significant airway obstruction, mainly located at the peripheral level, was demonstrated by a reduced specific lung conductance and upstream conductance in 13 subjects. Airway obstruction was not associated with smoking habits. Bronchial hyperresponsiveness was noted in 50% of the 18 subjects studied. Although fibrosis was mild to moderate in 15 instances, it was only focal, i.e. at least one zone of normal parenchyma in the lung specimen in 17 subjects. Peribronchial fibrosis was established in 8/11 satisfactory biopsy specimens. Significant correlations were observed between rales, the radiological score, some functional indices and the characteristics of fibrosis. We conclude that small airway obstruction documented by physiological and pathological means is frequent in early stage idiopathic pulmonary fibrosis. PMID:3420306

These biobanks are a valuable research resource for many diseases, particularly if they can be linked to high quality population-based health registries, allowing large retrospective epidemiological studies to be carried out. Such studies are of significant importance, for example in the search for novel prognostic and predictive biomarkers in the era of personalized medicine. Denmark has a wealth of highly-regarded population-based registries that are ideally suited to conduct this type of epidemiological research. We describe two recent additions to these databases: the Danish National Pathology Registry (DNPR and its underlying national online registration database, the Danish Pathology Data Bank (DPDB. The DNPR and the DPDB contain detailed nationwide records of all pathology specimens analyzed in Denmark since 1997, and an incomplete but nonetheless valuable record of specimens from some pathology departments dating back to the 1970s. The data are of high quality and completeness and are sufficient to allow precise and efficient localization of the specimens. We describe the relatively uncomplicated procedures required to use these pathology databases in clinical research and to gain access to the archived specimens.Keywords: cohort profile, epidemiology, paraffin blocks, pathology

  3. Development of an instrument to measure the clinical learning environment in diagnostic radiology

    International Nuclear Information System (INIS)

    A clinical learning environment survey instrument was developed that provided insights into diagnostic radiology trainees' perceptions of the culture and context of the hospital-based training programme. The survey was completed by trainees allocated to 37 important training hospitals in Australia, New Zealand and Singapore in 2006. The main findings were that most obvious strengths of the diagnostic radiology programme are the wide variety of work-based learning opportunities and the social atmosphere. These were well regarded in all training sites. Work overload was seen as a significant problem in most hospitals and will probably remain a challenge. The areas that are most likely to repay efforts to bring about change are supervision and feedback. The study provides baseline data against which the influence of changes to the training programme may be evaluated.

    Virtual anthropology consists of the introduction of modern slice imaging to biological and forensic anthropology. Thanks to this non-invasive scientific revolution, some classifications and staging systems, first based on dry bone analysis, can be applied to cadavers with no need for specific preparation, as well as to living persons. Estimation of bone and dental age is one of the possibilities offered by radiology. Biological age can be estimated in clinical forensic medicine as well as in living persons. Virtual anthropology may also help the forensic pathologist to estimate a deceased person's age at death, which together with sex, geographical origin and stature, is one of the important features determining a biological profile used in reconstructive identification. For this forensic purpose, the radiological tools used are multislice computed tomography and, more recently, X-ray free imaging techniques such as magnetic resonance imaging and ultrasound investigations. We present and discuss the value of these investigations for age estimation in anthropology.

  5. The clinical and radiological evaluation of absence of the corpus callosum

    International Nuclear Information System (INIS)

    A retrospective and prospective analysis of children with a diagnosis of complete absence of the corpus callosum (ACC) at the Children's Memorial Hospital in Chicago over a 5-year period was performed. The diagnosis was based on the computed tomography (CT) and/or magnetic resonance (MR) images. From this material, 105 children with a diagnosis of ACC were analyzed on the basis of clinical symptomatology and radiological studies (CT, MR and ultrasound). Eighty-three percent of our children were symptomatic. The most common symptoms and signs were macrocephaly with hydrocephalus and seizures. MR was the best radiological imaging modality for evaluating children with ACC and associated brain anomalies. The most common associated brain anomalies with ACC in decreasing frequency in our children were: interhemispheric cyst with hydrocephalus, Dandy-Walker malformation, migrational disorders, absence of the inferior vermis, cephaloceles and lipoma aof the interhemispheric fissure.

    Clinical education programs in speech-language pathology enable the transition of students' knowledge and skills from the classroom to the workplace. Simulated clinical learning experiences provide an opportunity to address the competency development of novice students. This study reports on the validation of an assessment tool designed to evaluate speech-language pathology students' performance in a simulated clinical placement. The Assessment of Foundation Clinical Skills (AFCS) was designed to link to concepts and content of COMPASS(®): Competency Assessment in Speech Pathology, a validated assessment of performance in the workplace. It incorporates units and elements of competency relevant to the placement. The validity of the AFCS was statistically investigated using Rasch analysis. Participants were 18 clinical educators and 130 speech-language pathology students undertaking the placement. Preliminary results support the validity of the AFCS as an assessment of foundation clinical skills of students in this simulated clinical placement. All units of competency and the majority of elements were relevant and representative of these skills. The use of a visual analogue scale which included a pre-Novice level to rate students' performance on units of competency was supported. This research provides guidance for development of quality assessments of performance in simulated placements.

    A series of 13 cases of feline membranous nephropathy is presented. Two groups were distinguished clinically; eight cats had the nephrotic syndrome and five others were in renal failure but not nephrotic. The definitive diagnosis was based on histological, immunofluorescence and ultrastructural examinations of renal tissue obtained at renal biopsy or necropsy. Glomerular lesions were classified according to the degree of glomerular change into three distinct groups; mild, moderately severe and advanced. A relationship was established between the mild and moderately severe groups and cats with the nephrotic syndrome, and the advanced group and cats in renal failure. Diuretic therapy was satisfactory in initial control of oedema in the nephrotic cases. Monitoring of previously nephrotic cats for up to three years indicated that the disease is progressive, although in some cases it is sufficiently slow for a cat to live a relatively normal life without continuing treatment. The prognosis for cats presented in renal failure is hopeless. PMID:552741

    Background. Gastric cancer is discovered even after successful eradication of H. pylori. We investigated clinic pathological features of early gastric cancers after H. pylori eradication. Methods. 51 early gastric cancers (EGCs) from 44 patients diagnosed after successful H. pylori eradication were included as eradication group. The clinic-pathological features were compared with that of 131 EGCs from 120 patients who did not have a history of H. pylori eradication (control group). Results. Compared with control group, clinic-pathological features of eradication group were characterized as depressed (p EGC after H. pylori eradication are depressed, reddish appearances, which should be treated as a caution because histological diagnosis of cancerous tissue is sometimes difficult by endoscopic biopsy.

    Acute inflammatory lesions of the placenta consist of diffuse infiltration of neutrophils at different sites in the organ. These lesions include acute chorioamnionitis, funisitis, and chorionic vasculitis and represent a host response (maternal or fetal) to a chemotactic gradient in the amniotic cavity. While acute chorioamnionitis is evidence of a maternal host response, funisitis and chorionic vasculitis represent fetal inflammatory responses. Intraamniotic infection generally has been considered to be the cause of acute chorioamnionitis and funisitis; however, recent evidence indicates that "sterile" intraamniotic inflammation, which occurs in the absence of demonstrable microorganisms induced by "danger signals," is frequently associated with these lesions. In the context of intraamniotic infection, chemokines (such as interleukin-8 and granulocyte chemotactic protein) establish a gradient that favors the migration of neutrophils from the maternal or fetal circulation into the chorioamniotic membranes or umbilical cord, respectively. Danger signals that are released during the course of cellular stress or cell death can also induce the release of neutrophil chemokines. The prevalence of chorioamnionitis is a function of gestational age at birth, and present in 3-5% of term placentas and in 94% of placentas delivered at 21-24 weeks of gestation. The frequency is higher in patients with spontaneous labor, preterm labor, clinical chorioamnionitis (preterm or term), or ruptured membranes. Funisitis and chorionic vasculitis are the hallmarks of the fetal inflammatory response syndrome, a condition characterized by an elevation in the fetal plasma concentration of interleukin-6, and associated with the impending onset of preterm labor, a higher rate of neonatal morbidity (after adjustment for gestational age), and multiorgan fetal involvement. This syndrome is the counterpart of the systemic inflammatory response syndrome in adults: a risk factor for short- and long

    All patients presented a fracture of the collum mandibulae, which had occurred between 1 and 10 years before treatment. The patients were exclusively treated conservatively. 57 of 67 patients did not indicate any subjective pain. 10 patients complained about pain and restricted movability. In only 22 cases no pathologic findings were obtained in the clinical follow-up examinations. In 33 patients the roentgenologic follow-up examination led to pathologic findings. Severe complications as disturbance of growth and formation of ankyloses, occurred only in one single case, due to a fracture of the mandibular joint in childhood. (orig./MG)

    In Germany more than 3,500 people become infected with syphilis annually. As elsewhere in Western Europe there is a low level endemicity with a concentration among population subgroups with high rates of partner exchange, such as men who have sex with other men. In Germany after initially reduced numbers of cases, the incidence rate has increased after the turn of the millennium. In 2011 the incidence reached 4.5 cases per 100,000 inhabitants, which is the highest incidence since the introduction of the Infection Protection Act of 2001. Syphilis, like other sexually transmitted infections and diseases with its manifold clinical manifestations and complex diagnostics, is a large global problem for public health systems. The recent resurgence of syphilis presents a challenge for all physicians but particularly for dermatologists and venereologists because the skin and adjacent mucous membranes are initially affected. Rapid diagnosis, differential diagnosis, consequent treatment and monitoring can cure the disease. Prevention of misdiagnosis is essential otherwise severe, sometimes fatal cardiovascular complications, neurosyphilis and transfer to unborn and newborn children can occur. The synergy of syphilis and sexually transmitted human immunodeficiency virus (HIV) is of special importance. Syphilis together with genital herpes and other sexually transmitted genital and oral ulcers is an important pacemaker for HIV. PMID:24150827

    Full Text Available Arsenicosis is a multisystem disorder, with virtually no system spared from its vicious claw; though its predominant manifestations are linked to cutaneous involvement. Cutaneous effects take the form of pigmentary changes, hyperkeratosis, and skin cancers (Bowen′s disease, squamous cell carcinoma, and basal cell epithelioma. Peripheral vascular disease (blackfoot disease, hypertension, ischemic heart disease, noncirrhotic portal hypertension, hepatomegaly, peripheral neuropathy, respiratory and renal involvement, bad obstetrical outcome, hematological disturbances, and diabetes mellitus are among the other clinical features linked to arsenic toxicity. The effects are mediated principally by the trivalent form of arsenic (arsenite, which by its ability to bind with sulfhydryl groups present in various essential compounds leads to inactivation and derangement of body function. Though the toxicities are mostly linked to the trivalent state, arsenic is consumed mainly in its pentavalent form (arsenate, and reduction of arsenate to arsenite is mediated through glutathione. Body attempts to detoxify the agent via repeated oxidative methylation and reduction reaction, leading to the generation of methylated metabolites, which are excreted in the urine. Understandably the detoxification/bio-inactivation process is not a complete defense against the vicious metalloid, and it can cause chromosomal aberration, impairment of DNA repair process, alteration in the activity of tumor suppressor gene, etc., leading to genotoxicity and carcinogenicity. Arsenic causes apoptosis via free radical generation, and the cutaneous toxicity is linked to its effect on various cytokines (e.g., IL-8, TGF-β, TNF-α, GM-CSF, growth factors, and transcription factors. Increased expression of cytokeratins, keratin-16 (marker for hyperproliferation and keratin-8 and -18 (marker for less differentiated epithelial cells, can be related to the histopathological findings of

    The application of radiation in human health, for both diagnosis and treatment of disease, is an important component of the work of the IAEA. The responsibility for the increasing technical aspects of this work is undertaken by the medical physicist. To ensure good practice in this vital area, structured clinical training programmes are required to complement academic learning. This publication is intended to be a guide to the practical implementation of such a programme for diagnostic radiology. There is a general and growing awareness that radiation medicine is increasingly dependent on well trained medical physicists based in the clinical setting. However, an analysis of the availability of medical physicists indicates a large shortfall of qualified and capable professionals. This is particularly evident in developing countries. While strategies to increase academic educational opportunities are critical to such countries, the need for guidance on structured clinical training was recognized by the members of the Regional Cooperative Agreement (RCA) for Research, Development and Training related to Nuclear Sciences for Asia and the Pacific. Consequently, a technical cooperation regional project (RAS6038) under the RCA programme was formulated to address this need in the Asia-Pacific region by developing suitable material and establishing its viability. Development of a clinical training guide for medical physicists specializing in diagnostic radiology started in 2007 with the appointment of a core drafting committee of regional and international experts. The publication drew on the experiences of clinical training programmes in Australia and New Zealand, the UK and the USA, and was moderated by physicists working in the Asian region.

  16. A guide to radiological research. The Research Sub-Committee of the Board of the Faculty of Clinical Radiology, the Royal College of Radiologists

    International Nuclear Information System (INIS)

    There are broad categories of radiological research. Basic science research undertaken in universities or in manufacturing companies may lead to new techniques or even new products like MRI, CT or contrast media. MRI is a product of university based research, while CT developed within a manufacturing company. Basic science type research is vital for the continuing development of our speciality, but requires considerable resources, teamwork, and research/management expertise. The best place for an interested radiologist to learn such skills is within university departments, typically in the context of an MD, Ph.D. or similar degree course. Clinical radiological research is of equal importance and, in the UK, underpins our international reputation for radiological excellence. Clinical research may be defined as research requiring patients. It can therefore only be carried out in hospitals and clinics. New technologies, drugs, indications, procedures etc., all require clinical research to validate them. The role of the clinical radiologist is pivotal to the proper conduct of clinical imaging research and technology assessment. This is not confined to university and teaching centres, but is of equal importance in district general hospitals. Results from clinical research carried out 'in the field' are the true test of our specialty. This research guide is sponsored by the RCR. Its target is radiologists and others carrying out clinical research within departments of radiology. If it stimulates Fellows and Members of the RCR to conduct more and better research then it will have succeeded in its basic objective. Research is always planned. It is based on observation, measurement and the testing of ideas or hypotheses. It is presented to peers for criticism and then published to be available to all for review. Research is always hard work and requires discipline. Like many things the ability to conduct research improves with practice. Many radiologists have not had much

    We describe a 16-month-old male with N540K homozygous mutation in the FGFR3 gene who showed a more severe phenotype than hypochondroplasia (HCH). To our knowledge, a homozygous state for this mutation causing HCH has not been reported before. The clinical and radiological characteristics of our patient represent an intermediate condition between achondroplasia and achondroplasia/hypochondroplasia compound heterozygosity. This case represents a new expression of FGFR3 spectrum and it is of considerable importance for the genetic counseling in cases where both parents are affected with HCH. PMID:24715719

    We present a case of a subdural osteoma. A 29-year-old female presented with a 3-year history of headaches. Computed tomography scan revealed a homogeneous high-density lesion isolated from the inner table of the frontal bone (a lucent dural line) in the right frontal convexity. Magnetic resonance imaging revealed an extra-axial lesion with a broad base without dural tail sign and punctate enhancement pattern characteristic of abundant adipose tissue. Upon surgical excision, we found a hard bony mass clearly demarcated from the dura. The mass displayed characteristics of an osteoma upon histological examination. The symptom was relieved after operation. PMID:27195262

  1. Clinical, radiological and cerebrospinal fluid presentation of neurocysticercosis: a prospective study

    Directory of Open Access Journals (Sweden)

    1990-09-01

    Full Text Available The wide clinical spectrum of neurocysticercosis has led to many attempts at clinical, radiological, CSF and other classifications. Based on an objective review of the relevant literature and on a prospective study of 42 patients with active neurocysticercosis, a new classification is proposed, based on clinical, tomographic, magnetic resonance and CSF evidence of viability of cysts. The first step is to define whether the disease is active or not. Inactive disease may be parenchymal calcifications or hydrocephalus. Active disease may be intraparenchymal, extraparenchymal or mixed. Statistical analysis of 42 cases with active disease shows intraparenchymal disease to occur in younger patients, perhaps more frequently in females, and to have a better prognosis than extraparenchymal of mixed disease. The latter appears to have the worst prognosis. Therapeutic implications are that only active disease warrants etiological therapy. There remain doubts about the best therapy for some infrequent subtypes of extraparenchymal and mixed disease.

    Neurofibromatosis type 1 is a genetic disease with an incidence of approximately 1 in 3,000 people, characterized mainly by systemic and progressive involvement, manifesting by physical deformity and compromising of neurological functions. The diagnosis of the neurofibromatosis type 1 must be performed the earliest possible through clinical exams and familiar history. The use of imaging diagnosis as radiography, computed tomography, and magnetic resonance imaging is valuable for diagnosis, treatment, follow-up of patients and control of lesions, preventing complications. In this study we describe the clinical and radiological aspects of the neurofibromatosis type 1, considering clinical features, genetics, bone alterations in chest, vertebral column, upper and lower limbs, and craniofacial abnormalities.

  3. Clinical application of FDG PET for pathological response of breast cancer after neo-adjuvant chemotherapy

    International Nuclear Information System (INIS)

    The purpose of this study was to assess the clinical usefulness of FDG PET in predicting the pathological response in breast cancer after neoadjuvant chemotherapy. 33 patients with newly diagnosed, locally advanced breast cancer had PET scans before and after chemotherapy to assess tumor response, and then pathology was confirmed after surgery. FDG PET for assessing tumor response was done by measuring peak SUV (pSUV) and then calculating reduction rate (RR). RR was stratified into RR complete response (rrCR) at >88% reduction, RR partial response (rrPR) at RR between 56∼87%, and no response (rrNR) in reductions <55%. Clinical assessment was done with physical exams, U/S, and CT. Histopathological response were classified into pathological no response(pNR), pathological partial response (pPR) and pathological complete response (pCR). 15% (5 of 33) patients had pCR, 85% (28 of 33) had pPR. Using a 88% reduction in SUV as a threshold value for differentiation between pCR from pPR, PET scans correctly differentiated pCR in 3 patients out of 5. When using a cut off value of 55% reduction rate, PET scans correctly differentiated pPR in 19 patients out of 21, and for pNR, the PET scans correctly differentiated only 2 patients out of 7. Diagnostic accuracy of PET for pathologic response was 25 out of 33 cases (75.8%). The diagnostic accuracy of clinical assessment was 25 of 33 cases (72.7%). This study suggests that pSUV reduction rate can be a useful tool when predicting the pathological response of primary breast cancers after neo-adjuvant chemotherapy

    Objective. To make a detailed evaluation of the clinical and radiological course of five children with chronic recurrent multifocal osteomyelitis (CRMO). Emphasis was laid on the correlation between clinical data and radiological findings. Design and patients. Clinical data, histology (n=11), bone scintigraphy (n=17), and the plain radiographs (n=198) of these patients were reviewed. The mean time of observation was 6.6 years (range 1-14.5 years). Thirty-two lesions seen at the time of primary diagnosis (n=22) or during the course of the disease (n=10) were evaluated. Twenty-seven foci were located in bone; in five cases the sacroiliac joints were involved. Results. Bone scintigrams showed nearly all foci (31/32) and were especially helpful in clinically asymptomatic lesions (14/32) or foci which were radiographically difficult to detect or not seen at all (8/32). Only 14 of 32 foci were locally symptomatic clinically. In all cases with a short interval ({<=}3 weeks) between the onset of local symptoms and evaluation by plain radiographs (n=5) osteolysis was shown without a sclerotic margin. All bone lesions with a longer duration of local symptoms (n=7) revealed a variable radiographic pattern: osteolysis with sclerotic rim in three, a mixed lytic-sclerotic lesion in three and pure sclerosis in one. In two cases low back pain could be ascribed to sacroiliitis. Conclusion. Only careful correlation between clinical, scintigraphy and radiographic features permits an accurate assessment of disease activity in CRMO. The bone lesions detected radiographically soon after the onset of symptoms resemble those of acute osteomyelitis. (orig.) 25 refs.

    Background Misinterpretation of radiological examinations is an important contributing factor to diagnostic errors. Consultant radiologists in Norwegian hospitals frequently request second reads by colleagues in real time. Our objective was to estimate the frequency of clinically important changes to radiology reports produced by these prospectively obtained double readings. Methods We retrospectively compared the preliminary and final reports from 1071 consecutive double-read abdominal CT examinations of surgical patients at five public hospitals in Norway. Experienced gastrointestinal surgeons rated the clinical importance of changes from the preliminary to final report. The severity of the radiological findings in clinically important changes was classified as increased, unchanged or decreased. Results Changes were classified as clinically important in 146 of 1071 reports (14%). Changes to 3 reports (0.3%) were critical (demanding immediate action), 35 (3%) were major (implying a change in treatment) and 108 (10%) were intermediate (requiring further investigations). The severity of the radiological findings was increased in 118 (81%) of the clinically important changes. Important changes were made less frequently when abdominal radiologists were first readers, more frequently when they were second readers, and more frequently to urgent examinations. Conclusion A 14% rate of clinically important changes made during double reading may justify quality assurance of radiological interpretation. Using expert second readers and a targeted selection of urgent cases and radiologists reading outside their specialty may increase the yield of discrepant cases. PMID:27013638

    Thyroid cancer may have small adipose structures detected by microscopy. However, there are no reports of thyroid cancer with gross fat evaluated by radiological methods. We reported a case of a 58-year-old woman with a fat containing thyroid mass. The mass was hyperechoic and ovoid in shape with a smooth margin on ultrasonography. On computed tomography, the mass had markedly low attenuation suggestive of fat, and fine reticular and thick septa-like structures. The patient underwent a right lobectomy. The mass was finally diagnosed as a follicular variant of papillary thyroid cancer with massive stromal fat.

    Sclerosing hemangioma is relatively rare, the second most common benign pulmonary neoplasm, which usually presents the peripheral location. Central location of this neoplasm is extremely rare with only a few reports. Herein, we would like to report an extremely rare case of central sclerosing hemangioma with descriptions of radiological characteristics. It was initially misdiagnosed as a papillary adenoma by bronchoscopic biopsy and mimicked central lung malignancies such as carcinoid tumors on non-invasive image evaluations. However the patient was finally confirmed with surgery.

    Full Text Available Background. Gastric cancer is discovered even after successful eradication of H. pylori. We investigated clinic pathological features of early gastric cancers after H. pylori eradication. Methods. 51 early gastric cancers (EGCs from 44 patients diagnosed after successful H. pylori eradication were included as eradication group. The clinic-pathological features were compared with that of 131 EGCs from 120 patients who did not have a history of H. pylori eradication (control group. Results. Compared with control group, clinic-pathological features of eradication group were characterized as depressed (p<0.0001, reddish (p=0.0001, and smaller (p=0.0095 lesions, which was also confirmed in the comparison of six metachronous lesions diagnosed after initial ESD and subsequent successful H. pylori eradication. Prevalence of both SM2 (submucosal invasion greater than 500 μm and unexpected SM2 cases tended to be higher in eradication group (p=0.077, 0.0867, resp.. Prevalence of inconclusive diagnosis of gastric cancer during pretreatment biopsy was also higher in the same group (26.0% versus 1.6%, p<0.0001. Conclusions. Informative clinic pathological features of EGC after H. pylori eradication are depressed, reddish appearances, which should be treated as a caution because histological diagnosis of cancerous tissue is sometimes difficult by endoscopic biopsy.

    The Pain Clinic of the CIMEQ offers treatment to patients with different pathologies, using interventional techniques as the radiology like visual guide to reach the target structure and to apply the election technique. The personnel that carry out these procedures are inserted in the program of radiological surveillance of the institution, reason for which a radiological event could be detected where the main physician responsible of the service was implied. In this work the results of an investigation are presented realized with the objective of to know the causes of the event and to determine the necessary measures to avoid that this repeats again. The investigation was oriented to three fundamental aspects: medical exam of the affected worker; evaluation of the operational procedures from the radiological protection view point; and dosimetric measurements simulating the real conditions of work for which were used ionization chamber, radiometer and PMMA mannequin. As a result of the medical exam was detected that the main physician of the service did not use during the execution of all the procedures the extremities dosimetry and that he presented a radio induced erythema in the right hand, reason for which he was separated of the activity with ionizing radiations, until the conclusion of the investigation. With relationship to the evaluation of the operational procedures from the radiological protection view point, was verified that the medical physician not carried out any collimation of the beam and he was located in the positions where the dose rate reached the maximum values, frequently introducing the hands in the direct beam; that which implied an overexposure of the superior extremities and a not optimized exposure for whole body. This result was proven with the realized experimental measurements, which gave dose estimated values in extremities of the order of the deterministic effects. The investigation facilitated to introduce modifications in the

  14. Anesthesia Practice and Clinical Trends in Interventional Radiology: A European Survey

    International Nuclear Information System (INIS)

    Purpose: To determine current European practice in interventional radiology regarding nursing care, anesthesia, and clinical care trends.Methods: A survey was sent to 977 European interventional radiologists to assess the use of sedoanalgesia, nursing care, monitoring equipment, pre- and postprocedural care, and clinical trends in interventional radiology. Patterns of sedoanalgesia were recorded for both vascular and visceral interventional procedures. Responders rated their preferred level of sedoanalgesia for each procedure as follows: (a) awake/alert, (b) drowsy/arousable, (c) asleep/arousable, (d) deep sedation, and (e) general anesthesia. Sedoanalgesic drugs and patient care trends were also recorded. A comparison was performed with data derived from a similar survey of interventional practice in the United States.Results: Two hundred and forty-three of 977 radiologists responded (25%). The total number of procedures analyzed was 210,194. The majority (56%) of diagnostic and therapeutic vascular procedures were performed at the awake/alert level of sedation, 32% were performed at the drowsy/arousable level, and 12% at deeper levels of sedation. The majority of visceral interventional procedures were performed at the drowsy/arousable level of sedation (41%), 29% were performed at deeper levels of sedation, and 30% at the awake/alert level. In general, more sedoanalgesia is used in the United States. Eighty-three percent of respondents reported the use of a full-time radiology nurse, 67% used routine blood pressure/pulse oximetry monitoring, and 46% reported the presence of a dedicated recovery area. Forty-nine percent reported daily patient rounds, 30% had inpatient hospital beds, and 51% had day case beds.Conclusion: This survey shows clear differences in the use of sedation for vascular and visceral interventional procedures. Many, often complex, procedures are performed at the awake/alert level of sedation in Europe, whereas deeper levels of sedation are

    Full Text Available Introduction: The Clinical and radiological manifestations of newborns with severe VDD have not been studied well. Materials and Methods: We studied the clinical, biochemical, and radiological manifestations of 10 full-term (FT newborns (6: M, 4: F infant presented to with symptomatic hypocalcemia (seizure secondary to vitamin D deficiency (VDD during the first 10 days of life are described. All were exclusively breastfed since birth. All their mothers have low 25 hydroxy vitamin D (25OHD level 60 ng/mL and 60% had decreased magnesium (Mg concentrations (<0.7 mmol/L. Their alkaline phosphatase (ALP concentrations were significantly higher than normal newborns. All other laboratory results (liver function tests, urea and electrolytes, C reactive protein, lumbar puncture, blood culture, and lactate were normal. In all patients, seizures ceased within 2 days of starting treatment with alphacalcidol and calcium. Radiological manifestations included metaphyseal band of relative lucency (osteopenia, just under the line of provisional calcification, within distal radius (7/10, femur (4/10, and tibia (3/10, mild cupping and haziness of distal radius (2/10. Discussion: Newborns with VDD had significantly lower serum calcium, ALP and PTH and higher phosphate concentrations, compared to older infants with VDD rickets. In newborns with VDD, serum calcium levels were correlated significantly with 25OHD (r = 0.597, P < 0.001, Mg concentrations (r = 0.436, P < 0.001 and negatively with ALP concentrations (r = −0.451, P < 0.001. Serum PTH concentrations were correlated significantly with serum Mg (r = 0.78, P < 0.0001 but not with serum calcium (r = −0.103, P = 0.3 or 25OHD (r = −0.03, P = 0.7 concentrations. Conclusion: The clinical, biochemical, and radiological manifestations of VDD in newborns indicate that they are less adapted to VDD compared to older infants. VD supplementation for mothers and newborns should be considered to avoid short

    Full Text Available Magnetic Resonance Imaging (MRI is an established tool in diagnosing and evaluating disease activity in Multiple Sclerosis (MS. While clinical-radiological correlations are limited in general, hypointense T1 lesions (also known as Black Holes (BH have shown some promising results. The definition of BHs is very heterogeneous and depends on subjective visual evaluation.We aimed to improve clinical-radiological correlations by defining BHs using T1 relaxation time (T1-RT thresholds to achieve best possible correlation between BH lesion volume and clinical disability.40 patients with mainly relapsing-remitting MS underwent MRI including 3-dimensional fluid attenuated inversion recovery (FLAIR, magnetization-prepared rapid gradient echo (MPRAGE before and after Gadolinium (GD injection and double inversion-contrast magnetization-prepared rapid gradient echo (MP2RAGE sequences. BHs (BHvis were marked by two raters on native T1-weighted (T1w-MPRAGE, contrast-enhancing lesions (CE lesions on T1w-MPRAGE after GD and FLAIR lesions (total-FLAIR lesions were detected separately. BHvis and total-FLAIR lesion maps were registered to MP2RAGE images, and the mean T1-RT were calculated for all lesion ROIs. Mean T1 values of the cortex (CTX were calculated for each patient. Subsequently, Spearman rank correlations between clinical scores (Expanded Disability Status Scale and Multiple Sclerosis Functional Composite and lesion volume were determined for different T1-RT thresholds.Significant differences in T1-RT were obtained between all different lesion types with highest T1 values in visually marked BHs (BHvis: 1453.3±213.4 ms, total-FLAIR lesions: 1394.33±187.38 ms, CTX: 1305.6±35.8 ms; p1500 ms (Expanded Disability Status Scale vs. lesion volume: rBHvis = 0.442 and rtotal-FLAIR = 0.497, p<0.05; Multiple Sclerosis Functional Composite vs. lesion volume: rBHvis = -0.53 and rtotal-FLAIR = -0.627, p<0.05.Clinical-radiological correlations in MS patients are

    International Nuclear Information System (INIS)

    Background. The manuscript presents a short history of the Clinical Radiology Institute in Ljubljana, University Clinical Centre, and the leading radiological institution in Slovenia since its establishment in 1923. Throughout its history the Institute has been faced with numerous obstacles. Its major problems have always included the lack of professional and economical independence, which has made it difficult for the Institute to keep up with the fast technological development of the world's radiology, as well as the shortage of radiologists and radiographers with the consequence of the excessive work load and difficulties in educational and research activities. Despite some serious problems the expertise of the Institute's leadership, together with the enthusiasm of all radiologists and radiographers, has enabled a continuous professional and technological development which is the basis of today's high quality diagnostic and interventional radiology. Many of the remarkable achievements would not have been possible without some extraordinary personalities who laid down the solid foundations of today's Institute. Conclusions. Eighty years of Clinical Radiology Institute in Ljubljana is a history of the successful development of the republic's leading radiological institution, a success based on determination, unity and the professional integrity of all its members and management.

    Shoulder impingement syndrome is a clinically common entity involving trapping of tendons or bursa with typical clinical findings. Important radiological procedures are ultrasound, magnetic resonance imaging (MRI) and MR arthrography. Projection radiography and computed tomography (CT) are ideal to identify bony changes and CT arthrography also serves as an alternative method in cases of contraindications for MRI. These modalities support the clinically suspected diagnosis of impingement syndrome and may identify its cause in primary diagnosis. In addition, effects of impingement are determined by imaging. Therapy decisions are based on a synopsis of radiological and clinical findings. The sensitivity and specificity of these imaging modalities with regard to the diagnostics of a clinically evident impingement syndrome are given in this review article. Orthopedic and trauma surgeons express the suspicion of an impingement syndrome based on patient history and physical examination and radiologists confirm structural changes and damage of intra-articular structures using dedicated imaging techniques.

    Background:Spinocerebellar ataxias (SCAs) are a group ofneurodegenerative disorders that primarily cause the degeneration in the cerebellum,spinal cord,and brainstem.We study the clinical characteristics,radiological features and gene mutation in Chinese families with SCAs.Methods:In this study,we investigated 10 SCAs Chinese families with SCA1,SCA3/Machado-Joseph disease (MJD),SCA7,SCAB.There were 27 people who were genetically diagnosed as SCA,of which 21 people showed clinical symptoms,and 6 people had no clinical phenotype that we called them presymptomatic patients.In addition,3 people with cerebellar ataxia and cataracts were diagnosed according to the Harding diagnostic criteria but failed to be recognized as SCAs on genetic testing.Clinical characteristic analyses of each type of SCAs and radiological examinations were performed.Results:We found that SCA3/MJD was the most common subtype in Han population in China,and the ratio of the pontine tegmentum and the posterior fossa area was negatively correlated with the number of cytosine-adenine-guanine (CAG) repeats;the disease duration was positively correlated with the International Cooperative Ataxia Rating Scale score;and the CAG repeats number of abnormal alleles was negatively correlated with the age of onset.Conclusions:Collectively our study is a systematic research on SCAs in China,which may help for the clinical diagnosis and prenatal screening of this disease,and it may also aid toward better understanding of this disease.

  20. Dopaminergic and clinical correlates of pathological gambling in Parkinson's disease: A case report

    Directory of Open Access Journals (Sweden)

    Mette Buhl Callesen

    2013-07-01

    Full Text Available Dopaminergic medication for motor symptoms in Parkinson’s disease recently has been linked with impulse control disorders, including pathological gambling, which affects up to 8% of patients. Pathological gambling often is considered a behavioral addiction associated with disinhibition, risky decision-making, and altered striatal dopaminergic neurotransmission. Using [11C]raclopride with positron emission tomography, we assessed dopaminergic neurotransmission during Iowa Gambling Task performance. Here we present data from a single patient with Parkinson’s disease and concomitant pathological gambling. We noted a marked decrease in [11C]raclopride binding in the left ventral striatum upon gambling, indicating a gambling-induced dopamine release. The results imply that pathological gambling in Parkinson’s disease is associated with a high dose of dopaminergic medication, pronounced motor symptomatology, young age at disease onset, high propensity for sensation seeking, and risky decision-making. Overall, the findings are consistent with the hypothesis of medication-related pathological gambling in Parkinson’s disease and underscore the importance of taking clinical variables, such as age and personality, into account when patients with Parkinson’s disease are medicated, to reduce the risk of pathological gambling.

    Lumbar disc protrusion is common. Its clinical manifestations and treatments are closely related to the pathological changes; however, the pathological classification of lumbar disc protrusion is controversial. This article introduces a new pathological classification comprising four types of lumbar disc protrusion according to intraoperative findings. The damage-herniation type is probably caused by injury and is characterized by soft herniation, the capsule can easily be cut and the broken disc tissue blocks overflow or is easily removed. The broken disc substances should be completely removed; satisfactory results can be achieved by minimally invasive endoscopic surgery. The degeneration-protrusion type is characterized by hard and tough protrusions and the pathological process by degeneration and proliferative reaction. The nerve should be decompressed and relaxed with minimally invasive removal of the posterior wall; the bulged or protruded disc often need not be excised. The posterior vertebral osteochondrosis with disc protrusion type is characterized by deformity of the posterior vertebral body, osteochondral nodules and intervertebral disc protrusion. The herniated and fragmented disc tissue should be removed with partially protruding osteochondral nodules. Intervertebral disc cyst is of uncertain pathogenesis and is characterized by a cyst that communicates with the disc. Resection of the cyst under microscopic or endoscopic control can achieve good results; and whether the affected disc needs to be simultaneously resected is controversial. The new pathological classification proposed here is will aid better understanding of pathological changes and pathogenesis of lumbar disc protrusion and provides a reference for diagnosis and treatment.

    Full Text Available Abstract Objective Clinical symptoms and radiological changes are useful in monitoring patients with interstitial lung diseases (ILD. Neovascularization participates in the pathogenesis of idiopathic pulmonary fibrosis and other ILD. The objective of the study was to examine the relationships between angiogenic activity of sera from ILD patients and clinical or radiological status. Material and methods Serum samples were obtained from 83 patients with sarcoidosis, 31 with idiopathic pulmonary fibrosis (IPF, 29 with hypersensitivity pneumonitis (HP, 16 with collagen diseases with pulmonary manifestation (CD, 13 with scleroderma (SCL, 14 with Wegener's granulomatosis (WG, 12 with pulmonary Langerhans cell histiocytosis (HIS, 12 with pneumoconiosis (PNC, 10 with drug-induced lung disease (DLD, 5 with cryptogenic organizing pneumonia (COP, and from 36 healthy volunteers. As an angiogenic test we used a cutaneous angiogenesis assay according to Sidky and Auerbach. Clinical status was evaluated using a special questionnaire. In all patients chest radiographs were performed. Results The angiogenic properties of sera from ILD differed depending on the clinical diagnosis. The strongest proangiogenic effect was induced by sera from patients with HP (mean number of new vessels 16.8, CD (16.6, sarcoidosis (16.3, IPF (16.2, and PNC (15.7. In the case of DLD (13.2, the effect was comparable to healthy controls (13.5. In contrast, sera from SCL (mean number of the vessels 10.5 and HIS patients (10.8 significantly inhibited angiogenesis compared with controls. The angiogenic activity of sera from patients with hilar or mediastinal lymph nodes involvement was higher than that of sera from patients with lung fibrosis. There were also differences in the serum angiogenic activity in relation to the severity of dyspnea. Conclusions The data showed that sera from ILD patients constitute a source of mediators modulating angiogenesis, but the pattern of reaction is

    There has been much recent public attention on the effects of the practices of cellular pathology on patients and their relatives. It is important to establish clearly pathologists' views about their professional relationships to clinicians and patients. A national postal questionnaire survey was performed to investigate how cellular pathologists perceive their role in clinical practice and whether there are important differences between different groups of pathologists. Responses were received from 773 pathologists, of whom 167 were trainees. On the basis of responses to 25 attitude statements, it appears that the profession shares a core belief that pathologists are clinicians rather than scientists and sees diagnosis as its main clinical responsibility. However, the role that each pathologist feels clear about differs significantly between pathologists, with a stronger consensus over function, responsibility, and professional image than on the clinical practice of pathology, job satisfaction, and the impact of technological change. Academic activities are a minority interest, although academic pathologists express better job satisfaction and more radical views of professional practice. Young trainees are more likely to work in teaching hospitals, to be female, to have trained outside the UK, and to have had experience in other specialties. They have, however, a more restricted view of the clinical role of pathology than accredited pathologists. Most cellular pathologists see themselves as clinicians with a special role in diagnosis, but how this is interpreted and the extent to which pathologists involve themselves in clinical decision-making is inconsistent. This professional dilemma should be addressed by research to obtain more systematic knowledge of the clinical impact of cellular pathology and especially the ill-defined links between diagnosis and clinical decision-making.

    Diagnosis, stratification and monitoring of disease progression in amyotrophic lateral sclerosis currently rely on clinical history and examination. The phenotypic heterogeneity of amyotrophic lateral sclerosis, including extramotor cognitive impairments is now well recognized. Candidate biomarkers have shown variable sensitivity and specificity, and studies have been mainly undertaken only cross-sectionally. Sixty patients with sporadic amyotrophic lateral sclerosis (without a family history of amyotrophic lateral sclerosis or dementia) underwent baseline multimodal magnetic resonance imaging at 3 T. Grey matter pathology was identified through analysis of T1-weighted images using voxel-based morphometry. White matter pathology was assessed using tract-based spatial statistics analysis of indices derived from diffusion tensor imaging. Cross-sectional analyses included group comparison with a group of healthy controls (n = 36) and correlations with clinical features, including regional disability, clinical upper motor neuron signs and cognitive impairment. Patients were offered 6-monthly follow-up MRI, and the last available scan was used for a separate longitudinal analysis (n = 27). In cross-sectional study, the core signature of white matter pathology was confirmed within the corticospinal tract and callosal body, and linked strongly to clinical upper motor neuron burden, but also to limb disability subscore and progression rate. Localized grey matter abnormalities were detected in a topographically appropriate region of the left motor cortex in relation to bulbar disability, and in Broca's area and its homologue in relation to verbal fluency. Longitudinal analysis revealed progressive and widespread changes in the grey matter, notably including the basal ganglia. In contrast there was limited white matter pathology progression, in keeping with a previously unrecognized limited change in individual clinical upper motor neuron scores, despite advancing disability

    Full Text Available The volume of the hippocampus measured with structural magnetic resonance imaging (MRI is increasingly used as a biomarker for Alzheimer's disease (AD. However, the neuropathologic basis of structural MRI changes in the hippocampus in the elderly has not been directly assessed. Postmortem MRI of the aging human brain, combined with histopathology, could be an important tool to address this issue. Therefore, this study combined postmortem MRI and histopathology in 100 elderly subjects from the Rush Memory and Aging Project and the Religious Orders Study. First, to validate the information contained in postmortem MRI data, we tested the hypothesis that postmortem hippocampal volume is smaller in subjects with clinically diagnosed Alzheimer's disease compared to subjects with mild or no cognitive impairment, as observed in antemortem imaging studies. Subsequently, the relations of postmortem hippocampal volume to AD pathology, Lewy bodies, amyloid angiopathy, gross infarcts, microscopic infarcts, and hippocampal sclerosis were examined. It was demonstrated that hippocampal volume was smaller in persons with a clinical diagnosis of AD compared to those with no cognitive impairment (P = 2.6 × 10(-7 or mild cognitive impairment (P = 9.6 × 10(-7. Additionally, hippocampal volume was related to multiple cognitive abilities assessed proximate to death, with its strongest association with episodic memory. Among all pathologies investigated, the most significant factors related to lower hippocampal volume were shown to be AD pathology (P = 0.0018 and hippocampal sclerosis (P = 4.2 × 10(-7. Shape analysis allowed for visualization of the hippocampal regions most associated with volume loss for each of these two pathologies. Overall, this investigation confirmed the relation of hippocampal volume measured postmortem to clinical diagnosis of AD and measures of cognition, and concluded that both AD pathology and hippocampal sclerosis affect hippocampal

  7. Spinal Cord Injury without Radiographic Abnormality (SCIWORA) – Clinical and Radiological Aspects

    International Nuclear Information System (INIS)

    The acronym SCIWORA (Spinal Cord Injury Without Radiographic Abnormality) was first developed and introduced by Pang and Wilberger who used it to define “clinical symptoms of traumatic myelopathy with no radiographic or computed tomographic features of spinal fracture or instability”. SCIWORA is a clinical-radiological condition that mostly affects children. SCIWORA lesions are found mainly in the cervical spine but can also be seen, although much less frequently, in the thoracic or lumbar spine. Based on reports from different authors, SCIWORA is responsible for 6 to 19% and 9% to 14% of spinal injuries in children and adults, respectively. Underlying degenerative changes, including spondylosis or spinal canal stenosis, are typically present in adult patients. The level of spinal cord injury corresponds to the location of these changes. With recent advances in neuroimaging techniques, especially in magnetic resonance imaging, and with increasing availability of MRI as a diagnostic tool, the overall detection rate of SCIWORA has significantly improved

  8. Pylon fractures of the ankle: A distinct clinical and radiological entity

    International Nuclear Information System (INIS)

    Pylon fractures are a distinct clinical and radiological entity that should not be confused with trimalleolar fractures. Radiographic and clinical comparison of 20 cases of each fracture type revealed definite distinguishing features. First, pylon fractures inevitably were associated with profound comminution of the distal tibia. The trimalleolar injury was associated with fractures of the medial, lateral, and posterior malleoli without comminution. Second, in contrast to timalleolar fractures, pylon fractures had intraarticular extension of at least one tibial fracture through the dome of the plafond. Third, 60% of all pylon fractures were associated with a fractured talus; the talus was intact in all trimalleolar fractures. Fourth, the distal tibiofibular syndesmosis was constant in the pylon fractures but was separated in all trimalleolar fractures

  9. Clinical and radiological study of osteoarticular manifestations of systemic lupus erythematosus

    International Nuclear Information System (INIS)

    The ostearticular involvement in systemic lupus erythematosus (SLE) is the most frequent manifestation of this illness, which develops with activity and remission periods. In spite of the recurrence, it presents without clinic sequelae in great part of the cases. The objective of this study was to evaluate patients with prolonged osteoarticular involvement, remaining with or without sequelae. Within a total of 115 patients with SLE there have been studied 21 patients that presented clinic evidences of chronic synovitis, deforming arthropathy with the presence of cysts, erosions, narrowing of the articular space, periepiphyseal osteopenia, and 4 cases with deforming arthropathy alone. In just 2 cases of chronic synovitis with radiologic changes there have been association with deforming arthropathy. Asseptic necrosis occurred in 8 cases being multiple and symmetric in 7 cases. The association with previous corticosteroid use was found in all patients, as well as an important systemic activity of the illness in the precedent period of the asseptic necrosis diagnosis.

    Full Text Available Objective To summarize the clinical data and pathological features of 10 cases of cerebral lobar hemorrhage related with cerebral amyloid angiopathy (CAA diagnosed pathologically, thereby to improve the knowledge and diagnosis of the disease. Methods The clinical data of 10 cases of cerebral lobar hemorrhage related with CAA, collected in the General Hospital of Shenyang Command from 1983 up to now, were retrospectively analyzed, and the clinical and neuropathological features of these cases were summarized. Results Of the 10 patients, 2 suffered from single lobar hemorrhage and 8 multiple lobar hemorrhage, all of them were confirmed pathologically to have ruptured into the subarachnoid space. Pathological examination revealed microaneurysm in 2 cases, "double barrel" change in 4 cases, multiple arteriolar clusters in 5 cases, obliterative onion-liked intima change in 4 cases, and fibrinoid necrosis of vessel wall in 7 cases. In addition, neurofibrillary tangles were found in 8 cases, and senile plaque was observed in 5 cases. Conclusions Cerebral lobar hemorrhage related with CAA is mainly located in the parietal, temporal and occipital lobes, readily breaking into the subarachnoid space, and it is often multiple and recurrent. The CAA associated microvasculopathy was found frequently in the autopsy sample of CAA related cerebral lobar hemorrhage, and it may contribute to the pathogenesis of cerebral hemorrhage.

    Full Text Available Objective To summarize the clinical and pathological features of pyogenic liver abscess (PLA in patients with diabetes mellitus (DM. Methods A retrospective study was performed to analyze the clinical and pathological data of 42 DM patients with PLA in 306 Hospital of PLA from January 2001 to December 2010. Results All the DM patients with PLA were cured without relapse and mortality, and the hospital stay was 19-57 days. Thirty-three patients received minimally invasive surgical treatment, including 10 percutaneous needle aspiration (PNA, 23 percutaneous catheter drainage (PCD, and 3 patients undergoing surgical excision, with full and uneventful recovery. Among the 10 patients undergoing PNA, 6 patients were cured after one aspiration procedure, 3 patients after two, and 1 patient after three aspirations. The drainage tubes were removed from patients who received PCD after a mean of 8.6 days. 3-4 days after surgery, the temperature of patients returned to normal, and no complications occurred. The pathological examination revealed numerous fibrous septa in the abscess cavity, inflammatory cells infiltration in the liver tissues surrounding the abscess, and the presence of Mallory bodies in the cytoplasm. The examination also showed that the number of glycogen granule in the hepatocyte was decreased, and the expression of cytokeratin 8 increased (P<0.05. Conclusion  More attention should be paid to DM with the complication of PLA because of its particular clinical and pathological characteristics.

    International Nuclear Information System (INIS)

    To investigate prognostic significance of clinical and pathological stages in patients with locally advanced rectal carcinoma treated with neoadjuvant chemoradiotherapy (neo-CRT) and total mesorectal excision. 210 patients with locally advanced rectal carcinoma (cT3-4 or cN+) treated with neo-CRT followed by total mesorectal excision. Treatment outcomes were compared according to clinical and pathological stage. Overall survival (OS), disease free survival (DFS) among patients with different clinical stage and pathological stage after neo-CRT. The median follow-up time was 47 months (range, 14–98 months). Clinical T stage was associated with 5 year OS (p = 0.042) and 5 year DFS (p = 0.014) while clinical N stage was not associated with 5 year OS (p = 0.440), 5 year DFS (p = 0.711). Pathological T stage was associate with 5 year OS (p = 0.001) and 5 year DFS (p = 0.046); and N stage was associated with 5 year OS (p = 0.001), 5 year DFS (p = 0.002). The pathological stage was further classified into three groups: ypT0–2N0 in 91 patients (43.3 %), ypT3–4N0 in 69 patients (32.9 %) and ypT0–4N+ in 50 patients (23.8 %). While pathological stage (ypT0–2 vs ypT3–4N0 vs ypT0–4N+) was associated with 5 year OS (87.9 %, 75.5 %, 56.7 %, p = 0.000), 5 year DFS (74.5 %, 77.4 %, 50.5 %, p = 0.003). Multivariate analysis showed that ypN stage was an independent prognostic factor for patients 5 year DFS. Pathological stage is strongly associated with treatment outcomes in patients with locally advanced rectal carcinoma treated with neo-CRT followed by total mesorectal excision, which may be used as guidance for further individualized treatment

    CO2 laser skin resurfacing devices are widely used in cosmetic surgery for the treatment of facial rhytides, acne scars and aging skin. This technique is also useful in the treatment of various benign and premalignant or multiple pathological skin conditions and disorders originating in the epidermal, dermal and skin appendages, vascular lesions, epidermal nevi, infected wounds and ulcers, and keloids. Various surgical techniques have been developed in our clinic using laser resurfacing in the treatment of more than 2,000 patients with various skin pathologic disorders. We describe our experience with the various techniques used. The precise depth control and ablation properties combined with the hemostatic and sterilizing effects of the CO2 laser beam, reduction of the possibility of bleeding, infection and damage to healthy tissues, make the CO2 laser resurfacing techniques the treatment of choice for cosmetic surgery and treatment of benign, premalignant and multiple pathologic skin conditions.

    The diagnosis of lateral epicondylitis is often straightforward and can be made on the basis of clinical findings. However, radiological assessment is valuable where the clinical picture is less clear or where symptoms are refractory to treatment. Demographics, aspects of clinical history, or certain physical signs may suggest an alternate diagnosis. Knowledge of the typical clinical presentation and imaging findings of lateral epicondylitis, in addition to other potential causes of lateral elbow pain, is necessary. These include entrapment of the posterior interosseous and lateral antebrachial cutaneous nerves, posterolateral rotatory instability, posterolateral plica syndrome, Panner's disease, osteochondritis dissecans of the capitellum, radiocapitellar overload syndrome, occult fractures and chondral-osseous impaction injuries, and radiocapitellar arthritis. Knowledge of these potential masquerades of lateral epicondylitis and their characteristic clinical and imaging features is essential for accurate diagnosis. The goal of this review is to provide an approach to the imaging of lateral elbow pain, discussing the relevant anatomy, various causes, and discriminating factors, which will allow for an accurate diagnosis.

  1. Foreign body aspiration in children: clinical aspects, radiological aspects and bronchoscopic treatment

    International Nuclear Information System (INIS)

    Objective: To describe the clinical manifestations and bronchoscopic treatment of foreign body aspiration in children under 14 years of age, correlating the clinical aspects with the bronchoscopic findings. Methods: A retrospective, descriptive study analyzing data related to children under 14 years of age undergoing bronchoscopy due to clinical suspicion of foreign body aspiration at the State University at Campinas Hospital das Clinicas from January of 2000 to December of 2005. Results: The sample consisted of 69 patients, ranging in age from 8 months to 12 years/7 months (75.4% under 3 years of age), 62.3% of whom were male. The principal complaint was sudden-onset cough (75.4%), auscultation was abnormal in 74%, and dyspnea was observed in 29%. Radiological abnormalities were seen in 88% of the cases. Aspirations were primarily into the right lung (54.8%), and 30.7% of the foreign bodies were of vegetal origin (principally beans and peanuts). In the follow-up period, 29% presented complications (most commonly pneumonia), which were found to be associated with longer aspiration time (p = 0.03). Mechanical ventilation was required in 7 children (10.1%), and multiple bronchoscopies were performed in 5 (7.2%). Conclusions: A history of sudden-onset choking and cough, plus abnormal auscultation and radiological findings, characterizes the profile of foreign body aspiration. In such cases, bronchoscopy is indicated. Longer aspiration time translates to a higher risk of complications. The high prevalence of foreign bodies of vegetal origin underscores the relevance of prevention at children younger than three years of age. (author)

  2. Study of the radiological procedures used in odontologic clinics of Boa Vista, Roraima, Brazil

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the radiological procedures used at the odontologic clinics of Boa Vista, Roraima-Brazil. The following parameters were recorded: field diameter, half value layer, total filtration, discrepancy between the preset and the applied kilovoltage and exposure time. Dose to the patient's skin from radiography of the upper molar tooth was also estimated. The results showed that 78% of the inspected units had field diameters larger than 6,0 cm, which is outside the limits recommended by the Brazilian Health Ministry. The results also showed that 14% of the equipment presented a discrepancy of more than 10% between preset and applied kilovoltage. On the other hand, the discrepancy between preset and applied exposure time is higher than 10% in 70% of the tested units. The total filtration of 77% units is lower than 1,5 mm of Al, a value recommended by the Brazilian Health Ministry for equipment that operates in the range of 50 kV to 70 kV. The survey also indicates that for 35% of the units the entrance dose in high than 3,5 mGy that is the reference value established by the Brazilian Health Ministry for dental radiography with film type. It was observed that the majority of the clinics use neither aprons nor collars for patients and that films are processed manually, without controlling temperature or processing time. Based on the results obtained it is strongly recommended that a quality control program be implemented in dental radiological clinics in Boa Vista, Roraima. (author)

    2014-12-01

    Five year survival rates for lung cancer patients are poor; however the development of new therapeutic options, which benefit subsets of the population, offer hope of improvement. These novel therapies frequently rely upon the analysis of biomarkers in pathology samples; in lung cancer patients, testing is now routinely carried out to identify small mutations and chromosomal rearrangements in order to predict response to treatment. The recent increase in biomarker analyses in pathology samples has lead to the development of a new specialty, molecular pathology. The use of molecular pathology assays in clinical samples is largely under the control of the histopathologist; who is likely to be asked, as a minimum, to select tissue sections for molecular analysis and mark areas of H&E stained slides for macro or microdissection. Many histopathologists will also be involved in the sourcing and implementation of new assays. This review aims to provide a guide to some of the most commonly used molecular pathology methods - their advantages and their limitations.

    AIM: To explore the relationship between clinical findings of patients with chronic liver diseases and the pathologic grading and staging of liver tissues.METHODS: The inflammatory activity and fibrosis of consecutive liver biopsies from 200 patients were determined according to the diagnosis criteria of chronic hepatitis in China established in 1995. A comparative analysis was carried out for 200 patients with chronic liver diseases by comparing their clinical manifestations, serum biochemical markers with the grading and staging of liver tissues.RESULTS: It was revealed that age, index of clinical symptoms and physical signs were obviously relevant to the pathologic grading and staging of liver tissues (P<0.05). Blood platelet, red blood cells, aspartate aminotransferase (AST),N-terminal procollagen Ⅲ (PⅢ NP) were apparently correlated with the degree of inflammation. PGA (prothrombin time,GGT, apoprotein A1) index, PGAA (PGA+△2-macroglobublin)index, albumin and albumin/globulin were relevant to both inflammation and fibrosis. Hyaluronic acid (HA) was an accurate variable for the severity of hepatic inflammation and fibrosis. The combination of serum markers for fibrosis could increase the diagnostic accuracy. It was notable that viral replication markers were not relevant to the degree of inflammation and fibrosis.CONCLUSION: There is a good correlation between clinical findings and the pathologic grading and staging of liver tissues, which may give aid to the noninvasive diagnosis of liver fibrosis.

    Background Acute rejection is one of the most important factors for prognosis following liver transplantation. With the use of potent immunosuppressants, acute rejection does not always present typical manifestations. Moreover, other complications often occur concomitantly after liver transplantation, which makes early diagnosis of acute rejection more difficult. Acute rejection is best diagnosed by liver biopsy. Differentiation of clinical manifestations and pathological features plays an important role in achieving individualized immunosuppressive treatment and prolonging long term survival of patients given orthotopic liver transplants.Methods From January 2004 to December 2006, 516 orthotopic liver transplantations were performed at the First Affiliated Hospital, Sun Yat-sen University. For patients who suffered acute rejection, clinical manifestations, histopathological features, diagnosis and anti-rejection treatment were summarized and analyzed. Results In 86 cases (16.7%), of the 516 recipients, 106 episodes of acute rejection occurred, which included 9 with histopathological borderline changes, 36 Banff Ⅰ rejections, 48 Banff Ⅱ and 13 Banff Ⅲ. Among these, 36 were cured by adjusting the dose of immunosuppressant and 65 were reversed by methylprednisolone pulse treatment. Five were methylprednisolone resistant, 3 of whom were given OKT3 treatment and 2 underwent liver retransplantation. Conclusions Due to potent immunosuppressive agents, acute rejection following an orthotopic liver transplantation lacks typical clinical manifestations and pathological features. Acute rejection is best diagnosed by liver biopsy. Designing rational individualized immunosuppressive regimen based on clinical and pathological features of acute rejection plays an important role in prolonging long term survival of patients.

    Examining 260 samples of pulmonary nodules obtained by percutaneous biopsy under tomodensitometric control from the departments of radiology and pathology over 10 years, the authors note the advantages and disadvantages of this technique, provide the results of their experience and emphasise the importance of these biopsies in malignant pathology. The results of this series can be superposed with those found in the literature. Malignant tumours account for 75 % of the cases, with a clear prevalence of primitive adenocarcinoma. Benign pathology (approximately, 14 % of the cases) was represented by necrosis without any specificity, fibrous reaction and infectious causes. The act had to be repeated for the false negatives (7 %). PMID:20933168

    Integrating clinical research data entry with patient care data entry is a challenging issue. At the G. Pompidou European Hospital (HEGP), cardiovascular radiology reports are captured twice, first in the Electronic Health Record (EHR) and then in a national clinical research server. Informatics standards are different for EHR (HL7 CDA) and clinical research (CDISC ODM). The objective of this work is to feed both the EHR and a Clinical Research Data Management System (CDMS) from a single multipurpose form. We adopted and compared two approaches. First approach consists in implementing the single "care-research" form within the EHR and aligning XML structures of HL7 CDA document and CDISC ODM message to export relevant data from EHR to CDMS. Second approach consists in displaying a single "care-research" XForms form within the EHR and generating both HL7 CDA document and CDISC message to feed both EHR and CDMS. The solution based on XForms avoids overloading both EHR and CDMS with irrelevant information. Beyond syntactic interoperability, a perspective is to address the issue of semantic interoperability between both domains. PMID:18693829

    Congenital esophageal stenosis (CES) can be associated with esophageal atresia/tracheoesophageal fistula (EA/TEF). Because there are a variety of degrees of obstruction and symptoms of CES, it is frequently difficult to make a pre- and post-operative diagnosis of the distal CES associated with EA/TEF. To evaluate the clinical and radiologic features of congenital esophageal stenosis associated with esophageal atresia/tracheoesophageal fistula. We retrospectively reviewed postoperative esophagograms and medical records of 187 children (107 boys, 80 girls) who had primary repair of EA/TEF from 1992 to 2009 at our institution. We evaluated the incidence of CES, clinical findings, radiologic features and management of CES in these children. CES was diagnosed in 22 of 187 EA/TEF children (12%); one child had double CES lesions, for a total of 23 lesions. Ten of those 22 children (45%) had presented with significant symptoms of esophageal obstruction. The diagnosis of CES was delayed in 10 children (45%) until 1-10 years of age. On esophagogram, CES (n = 23) was located in the distal esophagus (n = 20, 87%) or mid-esophagus (n = 3, 13%). The degree of stenosis was severe (n = 6, 26%), moderate (n = 10, 43%), or mild (n = 7, 30%). Eight children, including two with unsuccessful esophageal balloon dilatation of CES, were treated surgically. Histologic examination revealed tracheobronchial remnant (n = 7) or fibromuscular hyperplasia (n = 1). One child with surgically treated CES developed achalasia at the age of 3 years 9 months. Esophagography after EA/TEF repair should be performed with a high index of suspicion for the presence of distal CES, because the diagnosis and adequate management of CES can often be delayed.

  19. Radiation dose to children in diagnostic radiology. Measurements and methods for clinical optimisation studies

    International Nuclear Information System (INIS)

    A method for estimating mean absorbed dose to different organs and tissues was developed for paediatric patients undergoing X-ray investigations. The absorbed dose distribution in water was measured for the specific X-ray beam used. Clinical images were studied to determine X-ray beam positions and field sizes. Size and position of organs in the patient were estimated using ORNL phantoms and complementary clinical information. Conversion factors between the mean absorbed dose to various organs and entrance surface dose for five different body sizes were calculated. Direct measurements on patients estimating entrance surface dose and energy imparted for common X-ray investigations were performed. The examination technique for a number of paediatric X-ray investigations used in 19 Swedish hospitals was studied. For a simulated pelvis investigation of a 1-year old child the entrance surface dose was measured and image quality was estimated using a contrast-detail phantom. Mean absorbed doses to organs and tissues in urography, lung, pelvis, thoracic spine, lumbar spine and scoliosis investigations was calculated. Calculations of effective dose were supplemented with risk calculations for special organs e g the female breast. The work shows that the examination technique in paediatric radiology is not yet optimised, and that the non-optimised procedures contribute to a considerable variation in radiation dose. In order to optimise paediatric radiology there is a need for more standardised methods in patient dosimetry. It is especially important to relate measured quantities to the size of the patient, using e g the patient weight and length. 91 refs, 17 figs, 8 tabs

    Objectives: To evaluate the long-term clinical and radiological results from patients who underwent surgical treatment of chondroblastoma, between 2003 and 2009, by the same surgical team, using the same operative technique. Methods: A retrospective study was conducted on 12 patients with histological diagnoses of chondroblastoma, who were attended between 2003 and 2009 at the Pius XII Foundation (Barretos Cancer Hospital, Barretos, State of São Paulo). These patients underwent surgical treatment with intralesional resection of the tumor, adjuvant electrocauterization and replacement with methyl methacrylate (11 cases) or an autologous graft from the iliac crest (one case). The preoperative evaluation included physical examination, plain radiographs of the site, magnetic resonance imaging, computed axial tomography and bone scintigraphy. The patients were assessed clinically and radiologically according to a predefined protocol, with a series of plain radiographs, and a functional assessment in accordance with the Enneking functional score. Results: The average age at the time of diagnosis was 14 years and 4 months. The most frequent location affected was the distal femoral epiphysis (75%), followed by the proximal tibial epiphysis (16.6%) and the calcaneus (8.4%). There was higher prevalence among the female patients than among the male patients (3:1). In three cases, preoperative biopsy was necessary. During the follow-up, there was no evidence of local tumor recurrence, and all the patients presented an excellent functional result from the surgical technique used, with Enneking scores ranging from 20 to 30. Conclusion: Surgical treatment of chondroblastoma, using intralesional resection, adjuvant electrocauterization and replacement with methyl methacrylate or bone graft produced good results.

    Background Tumor involving the septum pellucidum is uncommon. Surgery as the main therapeutic procedure for this lesion is a challenge to neurosurgeons. We analyzed the clinical characteristics and pathological features of septum pellucidum tumor in 41 patients and compared the curative effects of frontal transcortical, trans-sulcal and interhemispheric transcallosal approaches. Methods Clinical characteristics and the pathological features of septum pellucidum tumor were investigated retrospectively in 41 patients. The differences in postoperative residual rates, extents of tumors and resection of normal brain tissues after use of the three approaches in these patients were analyzed statistically. Results Septum pellucidum tumor is more likely to attack young or middle-aged persons. The tumor mainly presents itself as a central neurocytoma or cerebral low-grade glioma in pathology and manifests as intracranial hypertension clinically. No difference was found in the extent of tumor resection but significant difference in the extent of normal brain tissue resection and in postoperative disability rate among the three approaches. The transcortical approach brought about the most serious injury to brain tissue and the highest disability rate, Whereas the frontal transcallosal approach the lightest injury and the lowest disability rate. The injury to brain tissue and the disability rate brought about by the front trans-sulcus approach were between the above two approaches. Conclusions Operation is still regarded the major treatment for septum pellucidum tumor. Transcallosal and trans-sulcus approaches are fit with the concept of minimally invasive surgery, and transcallosal approach is the first choice for septum pellucidum tumor.

    Ricin is a potential bioweapon that could be used against civilian and military personnel. Aerosol exposure is the most likely route of contact to ricin toxin that will result in the most severe toxicity. Early recognition of ricin exposure is essential if specific antidotes are to be applied. Initial diagnosis will most likely be syndromic, i.e., fitting clinical and laboratory signs into a pattern which then will guide the choice of more specific diagnostic assays and therapeutic interventions. We have studied the pathology of ricin toxin in rhesus macaques exposed to lethal and sublethal ricin aerosols. Animals exposed to lethal ricin aerosols were followed clinically using telemetry, by clinical laboratory analyses and by post-mortem examination. Animals exposed to lethal aerosolized ricin developed fever associated with thermal instability, tachycardia, and dyspnea. In the peripheral blood a marked neutrophilia (without immature bands) developed at 24 h. This was accompanied by an increase in monocytes, but depletion of lymphocytes. Red cell indices indicated hemoconcentration, as did serum chemistries, with modest increases in sodium and blood urea nitrogen (BUN). Serum albumin was strikingly decreased. These observations are consistent with the pathological observations of fluid shifts to the lungs, in the form of hemorrhages, inflammatory exudates, and tissue edema. In macaques exposed to sublethal aerosols of ricin, late pathologic consequences included chronic pulmonary fibrosis, likely mediated by M2 macrophages. Early administration of supportive therapy, specific antidotes after exposure or vaccines prior to exposure have the potential to favorably alter this outcome. PMID:26067369

  5. The Radiological Physics Center: 40 years of vigilance and quality assurance for NCI sponsored clinical trials

    International Nuclear Information System (INIS)

    The RPC was established in 1968 to contribute to the development, conduct, and QA of multi-institutional cooperative group clinical trials. One key aspect to the RPC's function is that it operates as an independent quality assurance office for multi-institutional cooperative group clinical trials. The RPC grant was originally awarded through a competition sponsored by the AAPM. In 1967, a memorandum of agreement was reached between the AAPM and the Committee for Radiation Therapy Studies (CRTS) for clinical radiation dosimetry related to inter-institutional studies. The agreement called for the establishment of a center of operations for the implementation of this scientific program, in other words, the creation of a Radiological Physics Center. The RPC has been funded continuously since 1968 under Dr. Shalek's guidance (1968-1985), followed by Dr. William Hanson (1985-2001) and currently by Dr. Geoffrey Ibbott (2001-present). The RPC currently monitors 1768 institutions that participate in cooperative group clinical trials sponsored by the National Cancer Institute (NCI). These institutions are located primarily in the USA and Canada, but also include participants from 30 other countries. Within the 1768 institutions, there are over 3300 megavoltage therapy machines that are monitored by the RPC QA program. In 1999, the RPC joined with several other QA offices to form the Advanced Technology Consortium (ATC). The role of the ATC is to support the development and conduct of advanced technology clinical trials, to facilitate communications among the four QA offices and to reduce duplication of effort among the quality assurance offices. The four major components of the RPC's QA program are: 1) the remote TLD audit of machine calibration, 2) on-site dosimetry review visits, 3) credentialing for advanced technology clinical trials, and 4) review of patient treatment records

    2014-05-01

    Molecular diagnostic testing of endometrial carcinomas in the pathology laboratory has recently emerged as a key component of the clinical evaluation of Lynch syndrome in many centers. Testing modalities involve immunohistochemical and PCR-based analyses. This article outlines the routine application of these analyses, provides a practical guide for troubleshooting some of the common technical issues related to their performance, and reviews common pitfalls in their interpretation. Discrepancies between tissue testing and genetic testing results are discussed in the context of the current understanding of endometrial cancer biology. The merits of universal versus targeted tissue testing based on clinical patient history and histological tumor appearance are also addressed.

Scans were performed on rat and mouse models of diseases or injuries on four radiology systems, tomosynthesis, computed tomography (CT, positron emission tomography/computed tomography (PET-CT, and Magnetic Resonance Imaging (MRI, based on the availability at the author’s institute. Results. Tomosysthesis delineated soft tissue anatomy and hard tissue structure with superb contrast and spatial resolution at minimal scan time and effort. CT allowed high resolution volumetric visualization of bones. Molecular imaging with PET was useful for detecting cancerous tissue in mouse but at the expense of poor resolution. MRI depicted abnormal or intervened tissue at quality and resolution sufficient for experimental studies. The paper discussed limitations of the clinical systems in preclinical imaging as well as challenges regarding the need of additional gadgets, modifications, or upgrades required for longitudinally scanning animals under anesthesia while monitoring their vital signs. Conclusion. Clinical imaging technologies can potentially make cost-effective and efficient contributions to preclinical efforts in obtaining anatomical, structural, and functional information from the underlying tissue while minimally compromising the data quality in certain situations.

    Full Text Available Abstract Introduction Composite tumors of the adrenal medulla or paraganglia are extremely rare and present a diagnostic dilemma. These tumors consist of a neuroendocrine component mixed with a neural component. We describe the imaging characteristics together with the corresponding pathological findings of a composite tumor. Apart from any component-specific imaging findings, the hallmark of this entity is the presence of histologically distinguishable components. Case presentation A 61-year-old Caucasian man was referred to our hospital due to a suspect lesion found on chest computed tomography carried out for unclear thoracic pain. An abdominal computed tomography scan and ultrasound examination detected a retroperitoneal tumor comprising two different tumor components. Twenty-four-hour urine revealed high levels of normetanephrine, characteristic of a neuroendocrine tumor. An octreoscan prior to surgical procedures revealed multiple osseous and intra-hepatic metastases. The final histopathological workup revealed a composite paraganglioma with neuroblastoma. Our patient died ten months after the initial diagnosis from tumor-associated complications. Conclusions Composite paragangliomas with neuroblastoma are rare tumors of the retroperitoneum. Such tumors should be considered in the differential diagnosis of retroperitoneal masses.

    Because the majority of patients present advanced disease at diagnosis, the management of epithelial ovarian cancer needs specialist multidisciplinary teamwork. Expertise in surgery, chemotherapy, imaging and histopathology is essential to achieve optimum outcomes. Computed tomography scans are routinely used to determine the extent of disease and to aid in surgical planning. The histologic classification is crucial to plan the best therapeutic strategy and to define the prognosis of disease. Pathological prognostic factors, such as degree of differentiation, FIGO-stage, and histological type have to be described. This report is fundamental to assessing prognosis and selection of appropriate treatment strategy. An adequate staging procedure is an extensive staging by an experienced gynecological oncologist, exploring the entire upper abdomen, and the pelvic and para-aortic lymph node regions to define the Peritoneal Cancer Index (PCI). The final assessment is the completeness of cytoreduction (CC) score, which is an assessment of residual disease after a maximal surgical effort. Initial management of advanced ovarian cancer is best provided by a specialist multidisciplinary team, including a radiologist, a pathologist, a gynecologic oncologist and a medical oncologist.

    To evaluate chest CT features of pulmonary tuberculosis mimicking lung malignancy. We retrospectively reviewed chest CT findings for 76 consecutive patients (21-84 years, average: 63 years; M : F = 30 : 46) who underwent an invasive diagnostic procedure under the suspicion of lung cancer and were pathologically diagnosed as pulmonary tuberculosis by bronchoscopic biopsy (n = 49), transthoracic needle biopsy (n = 17), and surgical resection (n = 10). We categorized the chest CT patterns of those lesions as follows: bronchial narrowing or obstruction without a central mass like lesion (pattern 1), central mass-like lesion with distal atelectasis or obstructive pneumonia (pattern 2), peripheral nodule or mass including mass-like consolidation (pattern 3), and cavitary lesion (pattern 4). CT findings were reviewed with respect to the patterns and the locations of the lesions, parenchymal abnormalities adjacent to the lesions, the size, the border and pattern of enhancement for the peripheral nodule or mass and the thickness of the cavitary wall in the cavitary lesion. We also evaluated the abnormalities regarding the lymph node and pleura. Pattern 1 was the most common finding (n = 34), followed by pattern 3 (n = 23), pattern 2 (n = 11) and finally, pattern 4 (n = 8). The most frequently involving site in pattern 1 and 2 was the right middle lobe (n = 14/45). However, in pattern 3 and 4, the superior segment of right lower lobe (n = 5/31) was most frequently involved. Ill-defined small nodules and/or larger confluent nodules were found in the adjacent lung and at the other segment of the lung in 31 patients (40.8%). Enlarged lymph nodes were most commonly detected in the right paratracheal area (n = 9/18). Pleural effusion was demonstrated in 10 patients. On the CT, pulmonary tuberculosis mimicking lung cancer most commonly presented with bronchial narrowing or obstruction without a central mass-like lesion, which resulted in distal atelectasis and obstructive

    Huntington’s disease is a neurodegenerative disorder caused by an abnormal CAG repeat expansion within exon 1 of the huntingtin gene HTT. While several genetic modifiers, distinct from the Huntington’s disease locus itself, have been identified as being linked to the clinical expression and progression of Huntington’s disease, the exact molecular mechanisms driving its pathogenic cascade and clinical features, especially the dementia, are not fully understood. Recently the microtubule associated protein tau, MAPT, which is associated with several neurodegenerative disorders, has been implicated in Huntington’s disease. We explored this association in more detail at the neuropathological, genetic and clinical level. We first investigated tau pathology by looking for the presence of hyperphosphorylated tau aggregates, co-localization of tau with mutant HTT and its oligomeric intermediates in post-mortem brain samples from patients with Huntington’s disease (n = 16) compared to cases with a known tauopathy and healthy controls. Next, we undertook a genotype–phenotype analysis of a large cohort of patients with Huntington’s disease (n = 960) with a particular focus on cognitive decline. We report not only on the tau pathology in the Huntington’s disease brain but also the association between genetic variation in tau gene and the clinical expression and progression of the disease. We found extensive pathological inclusions containing abnormally phosphorylated tau protein that co-localized in some instances with mutant HTT. We confirmed this related to the disease process rather than age, by showing it is also present in two patients with young-onset Huntington’s disease (26 and 40 years old at death). In addition we demonstrate that tau oligomers (suggested to be the most likely neurotoxic tau entity) are present in the Huntington’s disease brains. Finally we highlight the clinical significance of this pathology by demonstrating that the MAPT

    The use of standardized patients has been reported as a viable addition to traditional models of professional practice education in medicine, nursing and allied health programs. Educational programs rely on the inclusion of work-integrated learning components in order to graduate competent practitioners. Allied health programs world-wide have reported increasing difficulty in attaining sufficient traditional placements for students within the workplace. In response to this, allied health professionals are challenged to be innovative and problem-solving in the development and maintenance of clinical education placements and to consider potential alternative learning opportunities for students. Whilst there is a bank of literature describing the use of standardized patients in medicine and nursing, reports of its use in speech-language pathology clinical education are limited. Therefore, this paper aims to (1) provide a review of literature reporting on the use of standardized patients within medical and allied health professions with particular reference to use in speech-language pathology, (2) discuss methodological and practical issues involved in establishing and maintaining a standardized patient program and (3) identify future directions for research and clinical programs using standardized patients to build foundation clinical skills such as communication, interpersonal interaction and interviewing.

    Since the publication of the seminal work on the histology-based classification of vascular anomalies by Mulliken and Glowacki in 1982 and the subsequent adoption of an expanded and modified version in 1996 by the International Society for the Study of Vascular Anomalies, an increasing number of vascular lesions have been recognized as histologically distinct entities. Furthermore, there have been significant advances in detailing the behavior and underlying genetics of previously identified lesions. These developments have required restructuring and expansion of the classification scheme so that appropriate therapies may be studied and implemented in affected patients. The new classification retains the broad categories of neoplasms and malformations but now divides the tumor group into benign, locally aggressive or borderline, and malignant, with the malformation group being divided into simple, combined, those of major named vessels, and those associated with other anomalies. Additionally, a category has been created for lesions in which the histology and behavior do not yet allow clear separation into neoplasm or malformation (thus named "provisionally unclassified vascular anomalies"). The known clinical courses and imaging, histologic, and genetic findings of the most common and/or clinically relevant lesions in the newly adopted revised system are reviewed in this article.

    In our department, it is planned that the gastro-intestinal fluoroscopic area will be equipped entirely with digital imaging systems. The use of the 1024 X 1024 pixel frame store, backed by a hard disc for rapid image transfer, and the production of hard copy on a laser imager has reached the point where clinical efficacy and acceptance are assured. The further addition of facilities for annotation and the application of digital post-processing techniques are being explored both at the clinical site and at the research laboratorieS. The use of laser imaging has produced a further improvement in image quality and some of the practical problems related to this apparatus will be described. The availability of larger capacity laser disc image storage enables the local area network or "mini-PACS" system for fluoroscopy areas to become a concept worthy of investigation. We present our experience over a number of years with these systems, together with our latest investigations into potential applications of laser technology to the practice of radiology in a busy imaging centre.

    International Nuclear Information System (INIS)

    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

    International Nuclear Information System (INIS)

    To determine whether the significant relationship exists between radiographic appearance, whether it is unilocular or multilocular, and its corresponding clinical and histologic features by examining the odontogenic keratocyst clinically, radiologically and histologically. This study was conducted on 48 cases of odontogenic keratocyst from the files of Dental Hospital, Yonsei University for the years 1982 through 1995. The mean age of patients was 30.5 years in the unilocular group and 35.5 years in the multilocular group. The male to female ratio was 1:1.06 in the unilocular group and 1:1.75 in the multilocular group. The chief complaint was swelling in both groups (unilocular 35.1%, multilocular 54.5%). In the occurrence site, the border of the lesion, the displacement and external root resorption of the adjacent teeth, there were no statistically significant difference between the unilocular group and multilocular group, but in the border type, there was statistically significant difference (x2-test, p<0.05). Two recurred cases were observed among 11 cases of odontogenic keratocyst. One was unilocular case and the other was multilocular case.

    In acute promyelocytic leukemia, differentiation thera-py based on all-trans-retinoic acid can be complicated by the development of a differentiation syndrome(DS). DS is a life-threatening complication, characterized by respiratory distress, unexplained fever, weight gain, interstitial lung infiltrates, pleural or pericardial effusions, hypotension and acute renal failure. The diagnosis of DS is made on clinical grounds and has proven to be difficult, because none of the symptoms is pathognomonic for the syndrome without any definitive diagnostic criteria. As DS can have subtle signs and symptoms at presentation but progress rapidly, end-stage DS clinical picture resembles the acute respiratory distress syndrome with extremely poor prognosis; so it is of absolute importance to be conscious of these complications and initiate therapy as soon as it was suspected. The radiologic appearance resembles the typical features of cardiogenic pulmonary edema. Diagnosis of DS remains a great skill for radiologists and haematologist but it is of an utmost importance the cooperation in suspect DS, detect the early signs of DS, examine the patients’ behaviour and rapidly detect the complications.

    Summary Aim Hydroxyapatite (PA) has a chemical composition and physical structure very similar to natural bone and therefore it has been considered to be the ideal biomaterial able to ensure a biomimetic scaffold to use in bone tissue engineering. The aim of this study is to clinically test hydroxyapatite used as osteoconductive biomaterial in the treatment of periodontal bone defects. Clinical and radiological evaluations were conducted at 6, 12 and 18 months after the surgery. Materials and methods Forty patients with 2- and 3-wall intrabony pockets were enrolled in this study. PPD, CAL, radiographic depth (RD) and angular defects were preoperatively measured. After surgery, patients were re-evaluated every 6 months for 18 months. Statistical analyses were also performed to investigate any differences between preoperative and postoperative measurements. Results Paired t-test samples conducted on the data obtained at baseline and 18 months after, showed significant (p<0.01) differences in each measurement performed. The role of preoperative RD was demonstrated to be a significant key factor (p<0.01). A relevant correlation between preoperative PPD and CAL gain was also found. Conclusions Within the limitations of this study, the absence of anatomical variables, except the morphology of the bone defect, emphasizes the importance of the proper surgical approach and the graft material used.

    Post-radiation injury of patients with brain arteriovenous malformations (AVM) include blood-brain barrier breakdown (BBBB), edema, and necrosis. Prevalence, clinical relevance, and response to treatment are poorly known. We present a series of consecutive brain AVM treated with stereotactic radiosurgery describing the appearance of radiation injury and clinical complications. Consecutive patients with annual clinical and radiological follow-up (median length 63 months). Edema and BBBB were classified in four groups (minimal, perilesional, moderate, or severe), and noted together with necrosis. Clinical symptoms of interest were intracranial hypertension, new neurological deficits, new seizures, and brain hemorrhages. One hundred two cases, median age 34 years, 52 % male. Median irradiated volume 3.8 cc, dose to the margin of the nidus 18.5 Gy. Nineteen patients underwent a second radiosurgery. Only 42.2 % patients remained free from radiation injury. Edema was found in 43.1 %, blood-brain barrier breakdown in 20.6 %, necrosis in 6.9 %. Major injury (moderate or severe edema, moderate or severe BBBB, or necrosis) was found in 20 of 102 patients (19.6 %). AVM diameter >3 cm and second radiosurgery were independent predictors. Time to the worst imaging was 60 months. Patients with major radiation injury had a hazard ratio for appearance of focal deficits of 7.042 (p = 0.04), of intracranial hypertension 2.857 (p = 0.025), hemorrhage into occluded nidus 9.009 (p = 0.079), appearance of new seizures not significant. Major radiation injury is frequent and increases the risk of neurological complications. Its late appearance implies that current follow-up protocols need to be extended in time. (orig.)

  11. Comparative study of clinical, pathological and HRCT findings of primary alveolar proteinosis and silicoproteinosis

    International Nuclear Information System (INIS)

    Objective: To compare the clinical, high-resolution computed tomography (HRCT) and pathological findings of primary alveolar proteinosis (PAP) and silicoproteinosis. Material and methods: The study included 15 patients with PAP (6 women, 9 men, mean age 31 years) and 13 with silicoproteinosis (13 men, mean age 29.5 years). PAP was diagnosed by lung biopsy in 13 and bronchoalveolar lavage in two patients and silicoproteinosis by bronchoalveolar lavage in 10 and autopsy in three cases. HRCT images were reviewed by two chest radiologists with consensus for the presence, extent and distribution of ground-glass opacities, septal thickening, consolidation and nodules. Radiological–pathological correlation was performed by one radiologist and one chest pathologist. Results: Seven (46%) patients with PAP were asymptomatic; the remainder presented slowly progressive dyspnea and dry cough. All silicoproteinosis patients had dry cough and rapidly progressive dyspnea. The most common HRCT finding on PAP was the crazy-paving pattern (93%). All cases had areas of geographic sparing in the affected lung. The most common finding in silicoproteinosis (92%) was dependent consolidation with calcification in 83%. Centrilobular nodules were common (85%). On pathology, both diseases demonstrated intra-alveolar accumulation of PAS material, thickening of interlobular septae and alveolar walls and no evidence of fibrosis. A few silica particles were seen in silicoproteinosis. Conclusion: Despite the pathological similarities, PAP and silicoproteinosis have distinct clinical and imaging features and prognosis. Bilateral crazy-paving pattern with areas of geographic sparing is characteristic for PAP. Silicoproteinosis presents with bilateral dependent consolidation often with areas of calcification. The crazy-paving pattern is not seen in silicoproteinosis.

    Clinical prediction models are developed to calculate estimates of the probability of the presence/occurrence or future course of a particular prognostic or diagnostic outcome from multiple clinical or non-clinical parameters. Radiologic imaging techniques are being developed for accurate detection and early diagnosis of disease, which will eventually affect patient outcomes. Hence, results obtained by radiological means, especially diagnostic imaging, are frequently incorporated into a clinical prediction model as important predictive parameters, and the performance of the prediction model may improve in both diagnostic and prognostic settings. This article explains in a conceptual manner the overall process of developing and validating a clinical prediction model involving radiological parameters in relation to the study design and statistical methods. Collection of a raw dataset; selection of an appropriate statistical model; predictor selection; evaluation of model performance using a calibration plot, Hosmer-Lemeshow test and c-index; internal and external validation; comparison of different models using c-index, net reclassification improvement, and integrated discrimination improvement; and a method to create an easy-to-use prediction score system will be addressed. This article may serve as a practical methodological reference for clinical researchers.

    Huntington's disease is a neurodegenerative disorder caused by an abnormal CAG repeat expansion within exon 1 of the huntingtin gene HTT. While several genetic modifiers, distinct from the Huntington's disease locus itself, have been identified as being linked to the clinical expression...... and progression of Huntington's disease, the exact molecular mechanisms driving its pathogenic cascade and clinical features, especially the dementia, are not fully understood. Recently the microtubule associated protein tau, MAPT, which is associated with several neurodegenerative disorders, has been implicated...... in Huntington's disease. We explored this association in more detail at the neuropathological, genetic and clinical level. We first investigated tau pathology by looking for the presence of hyperphosphorylated tau aggregates, co-localization of tau with mutant HTT and its oligomeric intermediates in post...

    This report of the Whole Genome Analysis group of the Association for Molecular Pathology illuminates the opportunities and challenges associated with clinical diagnostic genome sequencing. With the reality of clinical application of next-generation sequencing, technical aspects of molecular testing can be accomplished at greater speed and with higher volume, while much information is obtained. Although this testing is a next logical step for molecular pathology laboratories, the potential impact on the diagnostic process and clinical correlations is extraordinary and clinical interpretation will be challenging. We review the rapidly evolving technologies; provide application examples; discuss aspects of clinical utility, ethics, and consent; and address the analytic, postanalytic, and professional implications.

  16. Radiologic-pathologic analysis of quantitative 3D tumour enhancement on contrast-enhanced MR imaging: a study of ROI placement

    International Nuclear Information System (INIS)

    To investigate the influence of region-of-interest (ROI) placement on 3D tumour enhancement [Quantitative European Association for the Study of the Liver (qEASL)] in hepatocellular carcinoma (HCC) patients treated with transcatheter arterial chemoembolization (TACE). Phase 1: 40 HCC patients had nine ROIs placed by one reader using systematic techniques (3 ipsilateral to the lesion, 3 contralateral to the lesion, and 3 dispersed throughout the liver) and qEASL variance was measured. Intra-class correlations were computed. Phase 2: 15 HCC patients with histosegmentation were selected. Six ROIs were systematically placed by AC (3 ROIs ipsilateral and 3 ROIs contralateral to the lesion). Three ROIs were placed by 2 radiologists. qEASL values were compared to histopathology by Pearson's correlation, linear regression, and median difference. Phase 1: The dispersed method (abandoned in phase 2) had low consistency and high variance. Phase 2: qEASL correlated strongly with pathology in systematic methods [Pearson's correlation coefficient = 0.886 (ipsilateral) and 0.727 (contralateral)] and in clinical methods (0.625 and 0.879). However, ipsilateral placement matched best with pathology (median difference: 5.4 %; correlation: 0.89; regression CI: [0.904, 0.1409]). qEASL is a robust method with comparable values among tested placements. Ipsilateral placement showed high consistency and better pathological correlation. (orig.)

    Objective: To evaluate the clinical and radiological medium-term results from surgical treatment of developmental hip dysplasia through Salter innominate bone osteotomy and Ombrédanne femoral shortening. Methods: Fourteen patients were evaluated, with surgical treatment on 18 hips (seven right-side hips and eleven left-side hips) using the proposal technique, performed between 1998 and 2008. The Dutoit and Severin criteria were used respectively for clinical and radiographic evaluations. Results: The average preoperative index for the seven right-side hips was 43.3° (40° to 50°), and this was corrected through surgery to an average of 31.57° (24° to 42°). The average preoperative index for the eleven left-side hips was 42.1° (36° to 56°), and this was corrected through surgery to an average of 30.36° (20° to 44°). There was a statistically significant difference between the preoperative and postoperative acetabular indexes, with P > 0.05. The clinical evaluation showed that there were seven excellent hips (38.9%), eight good ones (44.4%), three fair hips (16.7%) and no poor ones (0%). By grouping the hips rated good and excellent as satisfactory and those rated poor and fair as unsatisfactory, 83.3% of the results were seen to be favorable. There were no statistically significant correlations between occurrences of complications and patient age at the time of surgery or between complications and the preoperative acetabular index (p > 0.05). The complications observed consisted of one case each of subluxation, osteonecrosis and osteonecrosis together with subluxation. Conclusion: The combined procedure of Salter and Ombrédanne is a viable option for treating developmental hip dysplasia after patients have started to walk. PMID:27027068

    Purpose: To examine the clinical, radiologic and pathologic findings of occult inflammatory breast cancer (OIBC) in order to identify features useful for diagnosis. Materials and methods: We retrospectively reviewed the records of 19 women with OIBC observed at our Department between 1992 and 2001. We analysed the clinical history, mammographic, ultrasonographic, and pathologic findings and investigated overall survival (OS), prognostic variables and radio-pathologic correlations. Results: The most common mammographic findings were: diffusely density (52.63%), trabecular thickening (42.1%), mass (36.84%). The most common US findings were axillary lymphadenopathy (68,75%), skin thickening (43.75%) and mass (56.25%). At least one inflammatory sign was found in 14 women (74%) at mammography (subcutaneous thickening, trabecular thickening, diffuse increase of density) or at US (subcutaneous thickening, diffuse increase in echogenicity due to oedema, lymph vessel dilatation). Estrogen receptors (ER) were present in 63.2% and Progesterone receptors (PgR) in 36.8%. Significant prognostic variables were ER and Ki 67. Conclusions: The typical radiological pattern of clinical inflammatory breast carcinoma is less frequently present in OIBC; nevertheless the radiologist must pay attention because frequently OIBC presents just one radiological sign and this should be enough for a diagnostic suspicion. Moreover, the absence of clinical and radiological inflammatory signs does not exclude inflammatory breasts cancer because OIBC can manifest at imaging as a mass or isolated calcification. ER and PgR are positive in a high percentage of patients and confirm that OIBC has a better prognosis that clinical inflammatory breast cancer.

    The absence of a discrete mass, surrounding signal abnormality and solid enhancement are imaging features that have traditionally been used to differentiate soft-tissue arteriovenous malformations from vascular tumors on MRI. We have observed that these findings are not uncommon in arteriovenous malformations, which may lead to misdiagnosis or inappropriate treatment. To estimate the frequency of atypical MRI features in soft-tissue arteriovenous malformations and assess their relationship to lesion size, location, tissue type involved and vascular architecture. Medical records, MRI and histopathology were reviewed in consecutive patients with soft-tissue arteriovenous malformations in a multidisciplinary vascular anomalies clinic. Arteriovenous malformations were divided into those with and without atypical MRI findings (perilesional T2 signal abnormality, enhancement and/or a soft-tissue mass). Lesion location, size, tissue involved and vascular architecture were also compared between groups. Tissue stains were reviewed in available biopsy or resection specimens to assess relationships between MRI findings and histopathology. Thirty patients with treatment-naive arteriovenous malformations were included. Fifteen lesions demonstrated atypical MRI. There was no difference in age, gender, lesion size or involved body part between the groups. However, more than half of the atypical lesions demonstrated multicompartmental involvement, and tiny intralesional flow voids were more common in atypical arteriovenous malformations. Histopathology also differed in atypical cases, showing densely packed endothelial cells with connective tissue architectural distortion and edema. Arteriovenous malformations may exhibit features of a vascular tumor on MRI, particularly when multicompartmental and/or containing tiny internal vessels. These features are important to consider in suspected fast-flow vascular malformations and may have implications with respect to their treatment

    Clinical studies and preclinical investigations are essential in order to test new therapies and diagnostics with the aim of sustained improvement in the treatment of patients. Fortunately, the number of clinical studies is continuously increasing and pathology and tissue-based research are included more often. The German Society for Pathology (DGP) and the pathologists it represents want to and can support this process and our clinical partners as best as possible as an equal partner. With our technologies and our specific expertise we can make a substantial contribution to the quality and the success of preclinical investigations, clinical studies and implementation of the results into clinical pathological diagnostics. In order to support this process the DGP has formulated a statement on the participation and support of clinical studies and other scientific investigations.

    Full Text Available OBJECTIVES AND INTRODUCTION: Medullary thyroid carcinoma, a neoplasia of intermediate prognosis and differentiation, does not always respond predictably to known treatments. This study aimed to correlate the clinical progression of surgically treated patients with clinical and pathological data. METHODS: A total of 53 patients were followed for 75 months (mean average in tertiary-care hospital. The clinical status of patients at the end of the study period was characterized to determine correlations with a range of disease aspects. A value of p < 0.05 was considered statistically significant. RESULTS: Twenty-two patients (41.5% were alive and disease-free at the end of the follow-up period; twenty-three patients (43.4% had persistent disease; and eight patients (15.1% had recurrent disease. Four patients (7.6% died from medullary thyroid carcinoma with clinical and/or imaging evidence of neoplasia. The following aspects demonstrated statistically significant correlations with the final medical condition: positive initial cervical examination (p = 0.002; neoplastic extensions to the thyroid capsule (p = 0.004 and adjacent tissues (p = 0.034; cervical lymph node metastases (p < 0.001; diameter of neoplasia (p = 0.018; TNM (tumor, node and metastasis Stage (p = 0.001 and evidence of distant and/or cervical diseases in the absence of a cure (p = 0.011. Through logistic regression, the presence of cervical lymph node metastases was considered an independent variable (p < 0.001. CONCLUSIONS: Clinical and pathological aspects of patients with surgically treated medullary thyroid carcinomas are predictors of disease progression. Specifically, even treated cervical lymph node metastases are significantly correlated with disease progression.

    Many radiologists find it challenging to distinguish between the different interstitial idiopathic pneumonias (IIPs). The British Thoracic Society guidelines on interstitial lung disease (2008) recommend the formation of multidisciplinary meetings, with diagnoses made by combined radiological, pathological, and clinical findings. This review focuses on understanding typical and atypical radiological features on high-resolution computed tomography between the different IIPs, to help the radiologist determine when a confident diagnosis can be made and how to deal with uncertainty.

    Postmortem computed tomography (PMCT) is a modern tool that complements autopsy diagnostics. In clinical autopsies, a major cause of death is cardiovascular disease. To improve the performance of PMCT in cardiovascular disease, full body angiography was developed (PMCT angiography [PMCTA]). Twenty PMCTA scans generated before autopsy were compared with native PMCT and clinical autopsy. The objective of the study was to quantify the additional diagnostic value of adding angiography to native imaging and to compare PMCT and PMCTA findings to autopsy findings. The diagnosis of the cause of death was identical or overlapped in 80% of the cases that used PMCTA and 70% that used PMCT. The additional diagnostic yield given by PMCT and PMCTA in combination with autopsy was 55%. PMCT yielded additional diagnoses in the musculoskeletal system. The greatest additional diagnostic value of PMCTA was in association with cardiovascular diagnoses. The accuracy of PMCTA for cardiac causes of death was 80%, and the positive predictive value was 90%. The findings indicate that native PMCT cannot display the cardiovascular system sufficiently clearly for high-quality diagnostic assessment. However, PMCTA is a powerful tool in autopsy cases with a history of cardiovascular disease and/or a suspected cardiovascular cause of death. The combination of PMCTA and clinical autopsy enhances diagnostic quality and completeness of the autopsy report. Furthermore, in cases without consent or with a restricted consent for clinical autopsy, PMCTA has the potential to provide information on cardiovascular causes of death.

  9. The relationship between radiological features and clinical manifestation and dental expenses of keratocystic odontogenic tumor

    International Nuclear Information System (INIS)

    This study was performed to identify correlations between keratocystic odontogenic tumor (KCOT) data from CT sections, and data on the KCOT clinical manifestation and resulting dental expenses. Following local Institutional Review Board (IRB) approval, a seven-years of retrospective study was performed regarding patients with KCOTs treated at the Seoul National University Dental Hospital. A total of 180 KCOT were included in this study. The following information was collected: age, gender, location and size of the lesion, radiological features, surgical treatment provided and dental expenses. There was no significant association between the size of the KCOT and age, gender, and presenting preoperative symptoms. In both jaws, it was unusual to find KCOTs under 10 mm. The correlation between the number of teeth removed and the size of the KCOT in the tooth bearing area was statistically significant in the mandible, whereas in the maxilla, no significant relationship was found. Dental expenses compared with the size of the KCOT were found to be significant in both jaws. The size of KCOT was associated with a significant increase in dental expenses for both jaws and the number of teeth removed from the mandible. These findings emphasize the importance of routine examinations and early detection of lesions, which in turn helps preserving anatomical structures and reducing dental expenses.

    Full Text Available Introduction & Objective: Pulmonary Langerhans Cell Histiocytosis (PLCH is an uncommon (5% ILD interstitial tissue disorder with significant importance. It occurs predominantly in adult smokers. The organs involved in LCH include skin, bone, pituitary gland, thyroid, lymph node, and lungs.Materials & Methods: In this descriptive study all patients admitted to the Masih Daneshvari Hospital in Tehran from 1996 to 2007 diagnosed with LCH (recognized by clinical features, laboratory investigations, radiological manifestations, BAL and biopsy were evaluated.Results: A total of 20 patients were studied; mean age was 27.8 yrs.; 40% were smokers; 80% had pulmonary involvement while in 20% other organs were affected. On spirometry, a mixed pattern (50% was the most common and on chest radiography (CXR 77% of lung cysts were visible. The most frequent finding on CT- scan was diffuse lung cysts (80%.Conclusion: It is notable that ground glass opacity and consolidation occur in the early stages of disease. Since most of the patients refer with features of advanced disease, it is essential for the physicians to consider the early signs during the diagnostic stage. Also bronchoscopy and bronchial lavage are recommended in selected cases.

    Osteoporosis is the most common metabolic bone disease; vertebral fractures are the most common osteoporotic fractures. Several radiological scoring methods using different criteria for osteoporotic vertebral fractures exist. Quantitative morphometry (QM) uses ratios derived from direct vertebral body height measurements to define fractures. Semi-quantitative (SQ) visual grading is performed according to height and area reduction. The algorithm-based qualitative (ABQ) method introduced a scheme to systematically rule out non-fracture deformities and diagnoses osteoporotic vertebral fractures based on endplate depression. The concordance across methods is currently a matter of debate. This article reviews the most commonly applied standardised radiographic scoring methods for osteoporotic vertebral fractures, attaining an impartial perspective of benefits and limitations. It provides image examples and discusses aspects that facilitate large-scale application, such as automated image analysis software and different imaging investigations. It also reviews the implications of different fracture definitions for scientific research and clinical practice. Accurate standardised scoring methods for assessing osteoporotic vertebral fractures are crucial, considering that differences in definition will have implications for patient care and scientific research. Evaluation of the feasibility and concordance among methods will allow establishing their benefits and limitations, and most importantly, optimise their effectiveness for widespread application.

    This study was performed to identify correlations between keratocystic odontogenic tumor (KCOT) data from CT sections, and data on the KCOT clinical manifestation and resulting dental expenses. Following local Institutional Review Board (IRB) approval, a seven-years of retrospective study was performed regarding patients with KCOTs treated at the Seoul National University Dental Hospital. A total of 180 KCOT were included in this study. The following information was collected: age, gender, location and size of the lesion, radiological features, surgical treatment provided and dental expenses. There was no significant association between the size of the KCOT and age, gender, and presenting preoperative symptoms. In both jaws, it was unusual to find KCOTs under 10 mm. The correlation between the number of teeth removed and the size of the KCOT in the tooth bearing area was statistically significant in the mandible, whereas in the maxilla, no significant relationship was found. Dental expenses compared with the size of the KCOT were found to be significant in both jaws. The size of KCOT was associated with a significant increase in dental expenses for both jaws and the number of teeth removed from the mandible. These findings emphasize the importance of routine examinations and early detection of lesions, which in turn helps preserving anatomical structures and reducing dental expenses.

    Background: Location of tumor within the tracheobronchial tree as well as its severity can affect the clinical outcome of patients who undergo airway stent placement. Purpose: To evaluate radiologic and clinical outcome, including survival data, with special reference to proposed tumor involvement pattern, in patients with malignant bronchial strictures. Material and Methods: A total of 35 patients who underwent stent placement for malignant bronchial strictures were enrolled over a 9-year period. Tumor involvement pattern was divided into three types based on computed tomography (CT) scans and selective bronchography. Type I was defined as tumor involving only the main stem bronchus; type II, tumor involving the bronchus intermedius and/or the lower lobar bronchus without involvement of the lower-lobe segmental bronchus; and type III, tumor involving the lower lobar bronchus with involvement of the lower-lobe segmental bronchus. Tumor stage, lung collapse/infiltration, radiologic improvement, clinical improvement, and survival were compared according to the tumor involvement pattern. Results: Tumor involvement pattern was of type I, II, and III in 14, 13, and eight patients, respectively. When comparisons were made between types I/II and type III to evaluate the influence of lower-lobe segmental bronchial involvement, radiologic and clinical improvement was significantly lower in type III than in types I/II, while advanced stage, lung collapse/infiltration, and median overall survival were not significantly different between types I/II and type III. Conclusion: In patients with malignant bronchial obstructions involving the lower-lobe segmental bronchus, clinicians must be aware of the possibility of less radiologic and clinical improvement following stent placement

    Full Text Available Tibial plateau leveling osteotomy (TPLO is one of the tibial osteotomy techniques for canine cranial cruciate ligament rupture. The purpose of this study is to evaluate the clinically and radiologically findings of the patients with cranial cruciate ligament rupture treated by tibial plateau leveling osteotomy. In our clinical study, treatment of cranial cruciate ligament rupture in 18 dogs with a total of 20 stifles was performed. Cases were diagnosed with cranial cruciate ligament rupture, technical measurements for the operations are determined and the cases were prepared for the operation during the preoperative period of the clinical and radiological examinations. Following the operation, postoperative clinical and radiological evaluations were performed on the 10th, 30th, 60th, 90th and 120th days. At the end of the study, it was observed that the dogs retained stifle joint motion ability, early healing of the osteotomy side in the postoperative period, all stifle joint functions were retained after a period. It was determined that this method of operation can securely (in regards to joint stabilization be performed on especially in large breed dogs.

    Archived clinical pathology data (ACPD) is recognized as useful for research. Given our privileged de-identified ACPD from South West Pathology Service (SWPS), attempt is made to estimate what it would cost any researcher without such privilege to generate the same data. The Ethics Committee of the Area Health Service approved a request for Dr. Uba Nwose to use de-identified ACPD acquired by the SWPS for clinical laboratory-based translational biomedical science research. 10-years (1999-2008) have been pooled to constitute the database. Data include blood sugar, cholesterol, D-dime, ESR, glucose tolerance, haematocrit, HbA 1 c, homocysteine, serum creatinine, total protein and vitamins [C & E] amongst others. For this report, the bulk-billed-cost of tests were estimated based on number and unit price of each test performed. AU$ 17,507,136.85 is the cost paid by Medicare in the period. This amount is a conservative estimate that could be spent to generate such 10-years data in the absence of ACPD. The health/pathology service has not given any financial research grant. However, the support-in-kind is worth more than celebrated competitive research grants. It calls for revaluatrion by academic, research and scientific institutions the use ofACPD. For the countries where such provision is non-existent, this report provides a 'Position Paper' to present to the directorates or institutes of health authorities to appropriate the value of ACPD and approve of their use as a research treasure and resource management tool.

    Small bowel accounts for only 0.5% of cancer cases in the US but incidence rates have been rising at 2.4% per year over the past decade. One-third of these are adenocarcinomas but little is known about their molecular pathology and no molecular markers are available for clinical use. Using a retrospective 28 patient matched normal-tumor cohort, next-generation sequencing, gene expression arrays and CpG methylation arrays were used for molecular profiling. Next-generation sequencing identified novel mutations in IDH1, CDH1, KIT, FGFR2, FLT3, NPM1, PTEN, MET, AKT1, RET, NOTCH1 and ERBB4. Array data revealed 17% of CpGs and 5% of RNA transcripts assayed to be differentially methylated and expressed respectively (p clinically exploitable markers.

  19. Pulmonary opacification in infants undergoing extracorporeal membrane oxygenation (ECMO): Clinical and pathologic correlation

    International Nuclear Information System (INIS)

    The authors reviewed the chest radiographs and clinical records of 18 infants with severe respiratory failure treated with extracorporeal membrane oxygenation (ECMO) in order to determine the correlation between degree of abnormality on chest radiographs and the clinical severity of disease. In addition, the results of postmortem examinations of the lungs of seven infants who died while undergoing ECMO therapy were reviewed and compared with the radiographic appearance of the lung within 24 hours of death. Changes in lung compliance and ECMO requirements correlated well with improving radiographic appearance. Pathologic changes were mainly those associated with intensive respiratory support and/or the underlying pulmonary condition of the patient. One patient had diffuse pulmonary hemorrhage

    The receptor tyrosine kinase AXL is a member of the Tyro3-Axl-Mer receptor tyrosine kinase subfamily. AXL affects several cellular functions, including growth and migration. AXL aberration is reportedly a marker for poor prognosis and treatment resistance in various cancers. In this study, we analyzed clinical, pathological, and molecular features of AXL expression in lung adenocarcinomas (LADs). We examined 161 LAD specimens from patients who underwent pulmonary resections. When AXL protein expression was quantified (0, 1+, 2+, 3+) according to immunohistochemical staining intensity, results were 0: 35%; 1+: 20%; 2+: 37%; and 3+: 7% for the 161 samples. AXL expression status did not correlate with clinical features, including smoking status and pathological stage. However, patients whose specimens showed strong AXL expression (3+) had markedly poorer prognoses than other groups (P = 0.0033). Strong AXL expression was also significantly associated with downregulation of E-cadherin (P = 0.025) and CD44 (P = 0.0010). In addition, 9 of 12 specimens with strong AXL expression had driver gene mutations (6 with EGFR, 2 with KRAS, 1 with ALK). In conclusion, we found that strong AXL expression in surgically resected LADs was a predictor of poor prognosis. LADs with strong AXL expression were characterized by mesenchymal status, higher expression of stem-cell-like markers, and frequent driver gene mutations. PMID:27100677

    Objective: To investigate the clinical and pathological features of idiopathic membranous nephropathy (IMN) in Chinese adults. Methods: From 1986 to 1997, 264 patients with biopsy proven membranous nephropathy were selected in this study. Clinical and pathological features were compared between patients at different ages by t test. Results: (1) Patients from 21- 40 years old were inclined to membranous nephropathy. (2) One hundred and six of the patients had heavy proteinuria at presentation. Hypertension was found in 35 patients. Renal insuffeiency occurred in 7.7% of the patients in renal biopsy. Microscopic hematuria was found in 40.2% of the patients. Seventy-four patients presented nephrotic syndrome. (3) Eight of the 57 patients had deterioration of renal function during an average 49-month follow-up. (4) Patients of stage Ⅰ, Ⅱ, Ⅲ and Ⅳ accounted for 42.3%, 48.7%, 6.0% and 3.0% respectively. Glomeruli IgG, C3 and C1qdeposition was found in 93.2%, 98.8% and 58.3% of the patients. Conclusion: Younger patients are inclined to membranous nephropathy. The incidence of hypertension, microscopic hematuria and renal insuffcieney is similar to that of other countries, while nephrotic syndrome is uncommon.

  2. Randomized clinical trial on the use of antispasmodic drugs in barium enema: impact on radiological practice

    International Nuclear Information System (INIS)

    Purpose: To assess the willingness of radiologists to change their practice when the results of a randomized clinical trial (RCT) on the use of antispasmodic drugs in barium enema are presented. Materials and Methods: During the years 1994 and 1995 two postal questionnaires were sent to 481 practicing radiologists who were all members of the Netherlands Society of Radiology. In the first questionnaire the respondents were asked to give the characteristics of their practices in performing daily barium enema. The data from this questionnaire was used as a reference. The second questionnaire was sent to the respondents together with an abstract on the randomized clinical trial supporting the use of antispasmodic drugs in barium enema. We also indicated a preference for Buscopan over Glucagon as the antispasmodic drug. The willingness to change prescription habits was measured by comparing the data of the two questionnaires. Results: Of 481 practicing radiologists, 312 responded to the first questionnaire and gave information of their prescription habits (response rate 64%). These 312 responders were sent an abstract of the RCT and were asked to fill out a second questionnaire to determine their willingness to change their practice. Two hundred and sixty-seven radiologists responded (response rate 86%). A significant number of 119 (51%) were willing to increase the use of antispasmodic drugs. A significant number of 128 (55%) chose to increase the use of Buscopan, while a significant number of 81 (32%) were willing to decrease the use of Glucagon. Conclusion: Direct exposure to the results of an RCT recommending the use of antispasmodic drugs in barium enema, especially Buscopan, is likely to increase its use by practicing radiologists

  3. Clinical correlation of radiological spinal stenosis after standardization for vertebral body size

    International Nuclear Information System (INIS)

    Aim: To determine the relationship between the degree of radiographic lumbar spinal stenosis, adjusted with an internal control for vertebral body size, and disability from lumbar stenosis. Materials and methods: one hundred and twenty-three consecutive patients with clinical and radiological confirmation of neural impingement secondary to lumbar stenosis were enrolled prospectively. Thecal sac anteroposterior (AP) diameter (TSD) and cross-sectional area (CSA), and vertebral body AP dimension (VBD) were determined. These parameters were then correlated with patients' symptoms using the modified Roland-Morris questionnaire (RMQ) disability score. Results: No statistically significant inverse correlation was found between the TSD and RMQ score (p = 0.433), between the CSA and RMQ score (p = 0.124), or between the TSD:VBD ratio and RMQ score (p = 0.109). There was a significant positive correlation between the CSA:VBD ratio and RMQ score (p = .036), and therefore, there was no statistical support for an inverse relationship between the two. There was a significant difference in mean RMQ scores when the patients were divided into those with CSA greater than or equal to 70 mm2 and those less than 70 mm2, with T = -2.104 and p = 0.038. Conclusion: The degree of radiographic lumbar spinal stenosis, even with the use of an internal control of vertebral body size and standardized disability questionnaires, does not correlate with clinical symptoms. However, patients with more severe stenosis below a CSA critical threshold of 70 mm2, have significantly greater functional disability

    Full Text Available OBJECTIVE - To assess the incidence of fatal pulmonary embolism (FPE, the accuracy of clinical diagnosis, and the profile of patients who suffered an FPE in a tertiary University Hospital. METHODS - Analysis of the records of 3,890 autopsies performed at the Department of General Pathology from January 1980 to December 1990. RESULTS - Among the 3,980 autopsies, 109 were cases of clinically suspected FPE; of these, 28 cases of FPE were confirmed. FPE accounted for 114 deaths, with clinical suspicion in 28 cases. The incidence of FPE was 2.86%. No difference in sex distribution was noted. Patients in the 6th decade of life were most affected. The following conditions were more commonly related to FPE: neoplasias (20% and heart failure (18.5%. The conditions most commonly misdiagnosed as FPE were pulmonary edema (16%, pneumonia (15% and myocardial infarction (10%. The clinical diagnosis of FPE showed a sensitivity of 25.6%, a specificity of 97.9%, and an accuracy of 95.6%. CONCLUSION - The diagnosis of pulmonary embolism made on clinical grounds still has considerable limitations.

    Clinical terminologies are considered a key technology for capturing clinical data in a precise and standardized manner, which is critical to accurately exchange information among different applications, medical records and decision support systems. An important step to promote the real use of clinical terminologies, such as SNOMED-CT, is to facilitate the process of finding mappings between local terms of medical records and concepts of terminologies. In this paper, we propose a mapping tool to discover text-to-concept mappings in SNOMED-CT. Name-based techniques were combined with a query expansion system to generate alternative search terms, and with a strategy to analyze and take advantage of the semantic relationships of the SNOMED-CT concepts. The developed tool was evaluated and compared to the search services provided by two SNOMED-CT browsers. Our tool automatically mapped clinical terms from a Spanish glossary of procedures in pathology with 88.0% precision and 51.4% recall, providing a substantial improvement of recall (28% and 60%) over other publicly accessible mapping services. The improvements reached by the mapping tool are encouraging. Our results demonstrate the feasibility of accurately mapping clinical glossaries to SNOMED-CT concepts, by means a combination of structural, query expansion and named-based techniques. We have shown that SNOMED-CT is a great source of knowledge to infer synonyms for the medical domain. Results show that an automated query expansion system overcomes the challenge of vocabulary mismatch partially.

    2007-01-01

    Two institutions with different residency training formats in clinical pathology are compared with respect to application procedures, learning and teaching opportunities, learning resources, research training, publication requirements, and assessment methods of the program and trainees. The University of Florida and Purdue University programs are both based on an emphasis in morphologic recognition and interpretation of disease processes as well as training in basic science and applied research principles. The progress of trainees through each program is carefully monitored to meet individual needs as well as to meet the training requirements to allow candidates to sit for the certifying examination in clinical pathology. Periodic mock board exams are a critical tool to assess trainee progress and learning. The differences in format focus on coursework and publication requirements as well as on program assessment tools. While one program provides training in the form of 75% clinical diagnostic service, the other uses a mixture of 50% coursework and 50% clinical diagnostic training. Despite the contrast between a pure residency training program and one combining residency training with an MS degree, both institutions provide a solid program structure, ample learning resources, and adequate faculty mentorship to produce a high pass rate of board-certified specialists, the major focus for both programs. Numbers of post-training employment positions for both institutions are similar for those selecting faculty positions at veterinary schools. During the period studied, however, the combined residency and MS graduate program at Purdue University produced more graduates employed in pharmaceutical and biotechnology companies, while the residency program at the University of Florida produced more graduates employed by diagnostic laboratories.

  7. A new conversation between radiology and pathology-identifying microvascular architecture in stages of cirrhosis via diffraction enhanced imaging in vitro.

    Directory of Open Access Journals (Sweden)

    Dou-dou Hu

    Full Text Available BACKGROUND/AIM: Diffraction enhanced imaging (DEI is a synchrotron radiation X-ray phase-contrast imaging technique that can better reveal the microstructure of biological soft tissues than conventional X-rays. The aim of this study is to investigate the angio-architectural changes of the liver during fibrosis, cirrhosis and its subsequent regression by applying synchrotron radiation based DEI. METHODS: DEI experiments were performed at the 4W1A station of Beijing Synchrotron Radiation Facility. Twenty-four Sprague-Dawley rats were induced with liver fibrosis by carbon tetrachloride (CCl4 for up to 10 weeks, after which spontaneous regression started and continued until week 30. Quantitative analysis of the DEI images yielded the mean vascular density and intercapillary distance, which was then re-confirmed by immunohistochemical analysis of CD34. RESULTS: Based on the DEI results, the mean vascular density was 1.4-fold higher in fibrotic rats (at week 6 and 2-fold higher in cirrhotic rats (at week 10 compared with the control (p<0.05. Accordingly, the intercapillary distance decreased to 563.89 ± 243.35 µm in fibrotic rats and 392.90 ± 92.68 µm in cirrhotic rats compared with 673.85 ± 214.16 µm in the control (p<0.05. During fibrosis regression at week 30, vascular density was 0.7-fold lower and intercapillary distance increased to 548.60 ± 210.94 µm as compared with cirrhotic rats (p<0.05.In parallel to the DEI results, immunohistochemical analysis of CD34 showed similar changes. CONCLUSION: Synchrotron-based DEI can conduct radiological as well as pathological analysis. Our results are consistent with previous reports indicating that angiogenesis is directly proportional to fibrosis progression. Furthermore, by clarifying the vascular characteristics of liver diseases, DEI reveals that cirrhosis cannot fully reverse during fibrosis regression.

    Neurocysticercosis is a neurologic parasitic disease caused by the encysted larva of the tapeworm Taenia solium and is the most important parasitic disease of the human central nervous system. It is the most common cause of acquired epilepsy in endemic settings and constitutes a public health challenge for most of the developing world. Nowadays, however, as a result of globalization, neurocysticercosis is being seen more frequently in developed countries as well. Neurocysticercosis is acquired through fecal-oral contamination, and the disease course is complex, with two intermediate hosts (ie, pigs and humans) and a definitive host (humans). Traditionally, it has been classified into active and nonactive forms according to disease location. Radiologists must be aware of its imaging appearance, which is quite variable, as is the differential diagnosis. Imaging findings depend on several factors, including the stage of the life cycle of T solium at presentation; the number and location (ie, subarachnoid, cisternal, or intraventricular) of parasites; and associated complications such as vascular involvement (ie, arteritis with or without infarction), inflammatory response (ie, edema, gliosis, or arachnoiditis), and, in ventricular forms, degree of obstruction. Thus, the diagnostic approach, management, and prognosis for neurocysticercosis differ widely depending on the type of infection. PMID:21071384

    The current understanding of pathology as it relates to common diseases of the equine musculoskeletal system is reviewed. Conditions are organized under the fundamental categories of developmental, exercise-induced, infectious, and miscellaneous pathology. The overview of developmental pathology incorporates the new classification system of juvenile osteochondral conditions. Discussion of exercise-induced pathology emphasizes increased understanding of the contribution of cumulative microdamage caused by repetitive cyclic loading. Miscellaneous musculoskeletal pathology focuses on laminitis, which current knowledge indicates should be regarded as a clinical syndrome with a variety of possible distinct mechanisms of structural failure that are outlined in this overview.

    Full Text Available Introduction: Agreement between clinical and pathologic diagnoses plays an important role in an appropriate treatment plan and it may also prevent serious side effects and problems in patients. This study was conducted to assess the agreement between clinical diagnoses and pathologic reports in soft tissue lesions of patients referring to pathology department of dental school, Tehran and shahid Beheshti university of medical sciences during 2005-2008. Methods: In this retrospective and descriptive study, 300 soft tissue lesions of patients referring to pathology department were selected by census sampling method and then were analyzed. The lesions were classified according to the criteria proposed by reference pathology textbooks and the data records regarding the patients age, gender and clinical and pathologic diagnoses were noted. Concordance between two diagnoses was determined by descriptive statistics. Results: In this study, pathologic findings were golden standard (definitive diagnoses. The results showed the concordance between two clinical and pathologic diagnoses were more than 0/7 except POF and pemphigus. Conclusion: The results showed that the surgeons of oral and maxillofacial surgery in dental departments of Tehran and shahid Beheshti university of medical science provided acceptable diagnoses regarding pathologic lesions during 2005-2008. However, even the slight differences between two diagnoses necessitate all patients to be evaluated clinically and paraclinically in order to propose an accurate scientific diagnosis and prevent the harmful outcomes of the disease. Furthermore most efforts must be done to make more agreements between clinical and pathological diagnoses.

    Automatic detection of relevant terms in medical reports is useful for educational purposes and for clinical research. Natural language processing (NLP) techniques can be applied in order to identify them. In this work we present an approach to classify radiology reports written in Spanish into two sets: the ones that indicate pathological findings and the ones that do not. In addition, the entities corresponding to pathological findings are identified in the reports. We use RadLex, a lexicon of English radiology terms, and NLP techniques to identify the occurrence of pathological findings. Reports are classified using a simple algorithm based on the presence of pathological findings, negation and hedge terms. The implemented algorithms were tested with a test set of 248 reports annotated by an expert, obtaining a best result of 0.72 F1 measure. The output of the classification task can be used to look for specific occurrences of pathological findings. PMID:26262128

    Full Text Available OBJECTIVES: This study aimed to evaluate the hypothesis that relief of nasal obstruction in subjects with obstructive sleep apnea (OSA would lead to reduce OSA severity and to discuss the available evidence on the clinical efficacy of nasal surgery as a treatment modality for OSA. STUDY DESIGN: Twenty-five subjects who had reduced patency of nasal cavity and narrowing of retroglossal or retropalatal airways were diagnosed with OSA and underwent nasal surgery, such as septoplasty or turbinoplasty to correct nasal pathologies. The effect of the surgery on nasal patency was quantified by measuring minimal cross-sectional area (MCA using acoustic rhinometry. The watch-PAT-derived respiratory disturbance index (RDI, apnea and hypopnea index (AHI, lowest oxygen saturation, and valid sleep time were measured before and after nasal surgery. RESULTS: The present study shows that the AHI and RDI decreased significantly and the lowest oxygen saturation and valid sleep time rose after nasal surgery in 25 OSA subjects. In addition, a reduction in subjective symptoms was observed in subjects and mean MCA increased after nasal surgery. Fourteen subjects were classified as responders and 11 subjects as non-responders. Responders showed considerable improvement of their subjective symptoms and the AHI and RDI were significantly lower after surgery. We found that the changes between pre- and post-operative AHI and RDI values were minimal in 11 non-responders. However, daytime somnolence and REM sleep time improved after nasal surgery in non-responders. CONCLUSIONS: Our study provides evidence that the surgical treatment of nasal pathology improves nasal airway patency and reduces OSA severity in 56% subjects. Furthermore, correction of nasal pathology appears to result in improved sleep quality in both responder and non-responders OSA subjects.

  19. The clinical and radiological observation of the intususception in infancy and children

    International Nuclear Information System (INIS)

    Intussusception is the invagination of one portion of the intestine into the contiguous distal segment. During infancy and childhood it is the most common cause of acquired intestinal obstruction. This is a clinical and radiological study of 120 cases who visited our Chonnam National University Hospital from January 1975 to August 1979. The results were summarized as follows; 1. Age, sex and seasonal incidence. In 120 cases, 88.3% of the patients were under the one year of age and peak incidence occurred from 4 to 12 month of age. In sex distribution, male showed definitely higher incidence than in female patients with the ratio of 2.2 : 1. Although the disease occurs the year around, sprig and summer showed somewhat higher incidences. 2. The common symptoms and signs were vomiting (88.3%), bloody stool (81.7%), palpable mass (66.7%), and irritability (29.2%) in order of the frequency. 3. The common x-ray findings of plain abdomen were moderate dilatation of gas filled bowels loop (62.8%), obliteration of the gas shadow in the cecum ascending colon (5.0%), and soft tissue mass density (43%)> 4. The most common obstructing point found by barium enema was at the hepatic flexure. 5. The overall reduction rate by hydrostatic barium reduction was 69.4%, and this rate was increased in the following cases: 1) the duration of symptoms under the 12 hours (89.2%) and between 13 of 24 hour (70%). 2) no evidence of severe small bowel obstruction. 3) in the cases of ileocecal, ileocolic or colocolic of the type of intussusception. 6. Recurrence rate was 4.2%. 7. Mortality rate in 120 cases of intussusception was 2.5%.

    Full Text Available BACKGROUND: Tremendous advance in mechanization and fastness of travel have been accompanied by steep increase in number and severity of fractures and those of tibial plateau are no exception. Knee being one of the major weight bearing joints of the body, fractures around it will be of paramount importance. AIM OF STUDY: This study is to analyze the functional outcome of CRIF or ORIF with or without bone grafting in tibial plateau fractures in adults. MATERIALS AND METHODS: 30 cases of tibial plateau fractures treated by various modalities were studied from 1 - 8 - 2012 to 31 - 1 - 2014 at our institution and followed for a minimum of 6 months. Fractures were evaluated using Modified Rasmussen’s Clinical, Radiological grading system. RESULTS : The selected patients were evaluated thoroughly and after the relevant investigations, were taken for surgery. The fractures were classified as per the SCHATZKER’S types and operated accordingly with CRIF with Percutaneous cannulated cancellous screws, ORIF with buttress plate/LCP with or without bone grafting. Immobilization of fractures continued for 3 weeks by POP slab. Early range of motion was then started. Weight bearing up to 6 - 8 weeks was not allowed. The full weight bearing deferred until 12 weeks or complete fracture union . The knee range of motion was excellent to very good, gait and weight bearing after complete union was satisfactory, knee stiffness in 3 cases , wound dehiscence and infection in 1 case and non - union in none of our cases was noted. CONCLUSION: Functional outcome is better in operatively treated tibial plateau fractures in adults, because it gives excellent anatomical reduction and rigid fixation to restore articular congruity and early motion thereby preventing knee stiffness.

    Advanced stage hepatocellular carcinoma (HCC) is acategory of disease defined by radiological, clinical andhepatic function parameters, comprehending a widerange of patients with different general conditions. Themain therapeutic option is represented by sorafenibtreatment, a multi-kinase inhibitor with anti-proliferativeand anti-angiogenic effect. Trans-arterial Radio Embolizationalso represents a promising new approach tointermediate/advanced HCC. Post-marketing clinicalstudies showed that only a portion of patients actuallybenefits from sorafenib treatment, and an even smallerpercentage of patients treated shows partial/completeresponse on follow-up examinations, up against relevantcosts and an incidence of drug related adverse effects.Although the treatment with sorafenib has shown asignificant increase in mean overall survival in differentstudies, only a part of patients actually shows realbenefits, while the incidence of drug related significantadverse effects and the economic costs are relativelyhigh. Moreover, only a small percentage of patientsalso shows a response in terms of lesion dimensionsreduction. Being able to properly differentiate patientswho are responding to the therapy from non-respondersas early as possible is then still difficult and couldbe a pivotal challenge for the future; in fact it couldspare several patients a therapy often difficult to bear,directing them to other second line treatments (many ofwhich are at the moment still under investigation). Forthis reason, some supplemental criteria to be added tothe standard modified Response Evaluation Criteriain Solid Tumors evaluation are being searched for. Inparticular, finding some parameters (cellular density,perfusion grade and enhancement rate) able to predictthe sensitivity of the lesions to anti-angiogenic agentscould help in stratifying patients in terms of treatmentresponsiveness before the beginning of the therapyitself, or in the first weeks of sorafenib treatment

    Full Text Available Influenza A virus (IAV is a respiratory pathogen of pigs and is associated with the porcine respiratory disease complex (PRDC, along with other respiratory infectious agents. The aim of this study was to diagnose and to perform a clinic-pathological characterization of influenza virus infection in Brazilian pigs. Lung samples from 86 pigs in 37 farrow-to-finish and two farrow-to-feeder operations located in the States of Minas Gerais, São Paulo, Paraná, Rio Grande do Sul, Santa Catarina, and Mato Grosso were studied. Virus detection was performed by virus isolation and quantitative real time reverse-transcription PCR (qRT-PCR. Pathologic examination and immunohistochemistry (IHC were performed in 60 lung formalin-fixed paraffin-embedded tissue fragments. Affected animals showed coughing, sneezing, nasal discharge, hyperthermia, inactivity, apathy, anorexia, weight loss and growth delay, which lasted for five to 10 days. Influenza virus was isolated from 31 (36.0% lung samples and 36 (41.9% were positive for qRT-PCR. Thirty-eight (63.3% lung samples were positive by IHC and the most frequent microscopic lesion observed was inflammatory infiltrate in the alveoli, bronchiole, or bronchi wall or lumen (76.7%. These results indicate that influenza virus is circulating and causing disease in pigs in several Brazilian states.

    Full Text Available Squamous metaplasia of rete ovarii is characterized by replacement of the normal cuboidal epithelium of rete ovarii by a keratinized stratified scamous epithelium, leading to accumulation of keratinized material within the tubules and cystic dilatation of rete ovarii. The present study decribes a case of scamous metaplasia of rete ovarii in a 10 year old Zebu cow, including clinical, surgical, ultrasonographic, histopathological and hormonal findings. At first ultrasound examination the cow had lightly asymmetric ovaries with follicles presenting echogenicity similar to luteinized follicular cysts. After transvaginal follicular aspiration creamy yellowish sanguineous-purulent content was recovered. After unilateral ovariectomy the ovary was sectioned and brownish viscous material drained from cystic cavity. Histopathology confirmed the diagnosid of squamous metaplasia of the rete ovarii. Progesterone concentrations assessed by chemiluminescent enzyme immunoassay within different time periods after ovariectomy showed that pathology did not compromise normal luteal ovarian activity in a contralateral reminiscent ovary.

    Full Text Available A 3-year-old female Pinscher dog was presented with a history of lameness and pain in hind limbs for one week which acutely progressed to non-ambulatory paraparesis. The dog had been apathetic and anorexic during the six days prior to presentation. The neurological findings were compatible with upper motor neuron signs to the left hind limb due to a spinal cord compressive mass on the twelfth thoracic vertebral body. On the other hand, signs of lower motor neurons to the right hind limb were due to a mass with a pathological fracture in the right proximal femur, compressing the sciatic nerve. A histopathological analysis of all organs revealedthe proliferation of endothelial cells showingin filtrative growth and organization into vascular structures with a solid pattern. In addition, immunohistochemycal analysis revealed low proliferation index and citoplasmatic positivity for CD-31, confirming the vascular nature of the neoplasm. Clinical, histopathological and immunophenotipical findings were consistent with hemangiosarcoma.

    2003-01-01

    Full Text Available The epidemiology, clinical picture and pathology of an outbreak of urolithiasis in cattle in southern Brazil are described. The disease occurred in August 1999 in a feedlot beef cattle herd. Five out of 1,100 castrated steers were affected. Clinical signs included colic and ventral abdominal distension. White, sand-grain-like mineral deposits precipitated on the preputial hairs. Affected cattle died spontaneously 24-48 hrs after the onset of the clinical signs. Only one animal recovered after perineal urethrostomy. Necropsy findings included calculi blocking the urethral lumen of the distal portion of the penile sigmoid flexure, urinary bladder rupture with leakage of urine into the abdominal cavity and secondary fibrinous peritonitis. Daily water intake was low since water sources were scarce and not readily available. The animals were fed rations high in grains and received limited amounts of roughage. Biochemical analysis revealed that the calculi were composed of ammonium phosphate. A calcium-phosphorus imbalance (0.4:0.6 was detected in the feedlot ration. For the outbreak, it is suggested that contributing factors to urolith formation include insufficient fiber ingestion, low water intake and high dietary levels of phosphorus. No additional cases were obse
