    Alcock canal syndrome is a rare entrapment neuropathy of the pudendal nerve. We report a case of perineal neuralgia where pudendal nerve compression was due to fibrosis of the obturator internus muscle following an injury of the muscle. After being misdiagnosed for 2 years, the patient was diagnosed only after a combined neurophysiologic and magnetic resonance imaging (MRI) investigation. This case underlines the importance of performing focused neurophysiologic and neuroimaging studies in patients with neuropathic perineal pain in order to reach a correct diagnosis.

    To present a rare anomaly consisting of uterus didelphys, longitudinal vaginal septum, obstructed hemivagina with pyocolpos, fistula to the open vaginal canal, and ipsilateral renal agenesis, referred as Herlyn-Werner-Wunderlich syndrome (HWWS). A 14-year-old girl with recurring purulent vaginal discharge lasting for a few months. Preoperative examination revealed one vaginal canal with one cervical opening on the right side. There was a fistula leading from the obstructed vaginal canal to the left vagina. Intravaginal ultrasound examination demonstrated a longitudinal vaginal septum and a closed pyocolpos on the right side. The longitudinal vaginal septum was excised by way of electrocauterization under direct vision. HWWS should be considered in the differential diagnosis in patients with uterus didelphys and unusual symptoms such as pyocolpos and vaginal discharge.

    2014-03-18

    Tullio phenomenon refers to eye movements induced by sound.(1) This unusual examination finding may be seen in superior semicircular canal dehiscence (SSCD) syndrome.(2) This disorder is due to absent bone over the superior semicircular canal (figure). Patients complain of dizziness triggered by loud sound, aural fullness, autophony, and pulsatile tinnitus. When Tullio phenomenon exists in SSCD syndrome, the patient develops a mixed vertical-torsional nystagmus in which the slow phase rotates up and away from the affected ear (video on the Neurology® Web site at Neurology.org). This pattern of nystagmus aligns in the plane of the dehiscent semicircular canal and is due to excitation of its afferent nerves.

    Superior canal dehiscence syndrome (SCDS) is an increasingly recognized cause of hearing loss and vestibular symptoms, but the etiology of this condition remains unknown. To describe 7 cases of SCDS across 3 families. This retrospective case series included 7 patients from 3 different families treated at a neurotology clinic at a tertiary academic medical center from 2010 to 2014. Patients were referred by other otolaryngologists or were self-referred. Each patient demonstrated unilateral or bilateral SCDS or near dehiscence. Clinical evaluation involved body mass index calculation, audiometry, cervical vestibular evoked myogenic potential testing, electrocochleography, and multiplanar computed tomographic (CT) scan of the temporal bones. Zygosity testing was performed on twin siblings. The diagnosis of SCDS was made if bone was absent over the superior semicircular canal on 2 consecutive CT images, in addition to 1 physiologic sign consistent with labyrinthine dehiscence. Near dehiscence was defined as absent bone on only 1 CT image but with symptoms and at least 1 physiologic sign of labyrinthine dehiscence. A total of 7 patients (5 female and 2 male; age range, 8-49 years) from 3 families underwent evaluation. Family A consisted of 3 adult first-degree relatives, of whom 2 were diagnosed with SCDS and 1 with near dehiscence. Family B included a mother and her child, both of whom were diagnosed with unilateral SCDS. Family C consisted of adult monozygotic twins, each of whom was diagnosed with unilateral SCDS. For all cases, dehiscence was located at the arcuate eminence. Obesity alone did not explain the occurrence of SCDS because 5 of the 7 cases had a body mass index (calculated as weight in kilograms divided by height in meters squared) less than 30.0. Superior canal dehiscence syndrome is a rare, often unrecognized condition. This report of 3 multiplex families with SCDS provides evidence in support of a potential genetic contribution to the etiology

    To clarify which part of the median nerve is the most compressed and to compare carpal canal pressure with the latency of the sensory nerve potential and the duration of symptoms. Fifteen patients with idiopathic carpal tunnel syndrome were studied using a pressure guidewire system to record canal pressure. The wire was introduced from the distal end of the carpal canal to 2 cm proximal to the distal wrist crease (DWC) and then retracted in 5-mm increments using an image intensifier to guide the progress. A nerve conduction study was performed, and all patients were asked how long the symptoms lasted. Carpal canal pressure was significantly higher 5 to 15 mm distal to the DWC. The most compressed point was 10 mm distal to the DWC, with a pressure of 44.9 +/- 26.4 mm Hg. The correlation coefficient between the highest canal pressure and the latency was 0.393 and between highest canal pressure and duration of symptoms was 0.402. Our study showed that the most compressed part of the median nerve in the carpal canal is 10 mm distal to the DWC. The carpal canal pressure was related to the latency and to the duration of symptoms.

    Objectives (1) Evaluate changes in subjective symptoms in patients following transmastoid canal plugging for superior semicircular canal dehiscence (SSCD) syndrome. (2) Quantify changes in hearing in patients who have undergone transmastoid canal plugging for SSCD syndrome. Study Design Case series with chart review. Setting Single tertiary care institution. Subjects and Methods We retrospectively reviewed patients with SSCD who underwent repair with canal plugging via a transmastoid approach between January 2012 and January 2017. Symptom severity was assessed prospectively (autophony, sound/pressure-induced vertigo, disequilibrium, aural fullness, and pulsatile tinnitus) and after surgery. Pure-tone and speech audiometry were measured before and after surgery. Two-sided Wilcoxon rank-sum tests were used to evaluate changes in subjective symptoms and audiometric outcomes. Results Seventeen patients (19 ears) met inclusion criteria. The superior canal was successfully plugged via the transmastoid approach in all cases. Patients reported a statistically significant improvement in autophony, vertigo, aural fullness, and pulsatile tinnitus ( P study, patients with SSCD demonstrated excellent hearing outcomes and resolution of most otologic symptoms after surgical repair. Transmastoid canal plugging, which has been described to date only in smaller case series, is a safe and effective alternative to the traditional middle cranial fossa approach.

    Full Text Available Superior semicircular canal dehiscence syndrome was first reported by Lloyd Minor and colleagues in 1998. Patients with a dehiscence in the bone overlying the superior semicircular canal experience symptoms of pressure or sound-induced vertigo, bone conduction hyperacusis, and pulsatile tinnitus. The initial series of patients were diagnosed based on common symptoms, a physical examination finding of eye movements in the plane of the superior semicircular canal when ear canal pressure or loud tones were applied to the ear, and high-resolution computed tomography imaging demonstrating a dehiscence in the bone over the superior semicircular canal. Research productivity directed at understanding better methods for diagnosing and treating this condition has substantially increased over the last two decades. We now have a sound understanding of the pathophysiology of third mobile window syndromes, higher resolution imaging protocols, and several sensitive and specific diagnostic tests. Furthermore, we have a treatment (surgical occlusion of the superior semicircular canal that has demonstrated efficacy. This review will highlight some of the fundamental insights gained in SCDS, propose diagnostic criteria, and discuss future research directions.

    We report a case of bilateral partial absence of the posterior semicircular canals (with normal lateral semicircular canals) imaged with CT in a patient with Alagille syndrome. Similar histologic findings have been reported in the pathology literature. This association has been previously reported only for Waardenburg syndrome in the imaging literature. We review the imaging findings and embryology of the semicircular canals, and suggest that this abnormality is specific to patients with Alagille or Waardenburg syndrome. (orig.)

    This paper describes the CT findings that characterize the middle and inner ear anomalies in coloboma, heart defects, choanal atresia, mental retardation, genitourinary, and ear anomalies (CHARGE) syndrome. With this information, neuroradiologists will be better prepared to provide clinically relevant information to their referring physicians regarding this rare syndrome. CT studies from 13 patients were reviewed by 2 neuroradiologists with Certificate of Additional Qualification. Each ear was counted separately for a total of 26 ears. Middle and inner ear anomalies associated with CHARGE syndrome were categorized. Investigational review board approval was obtained. Twenty of 26 (77%) ears demonstrated cochlear aperture atresia. Four of these ears were evaluated with MR imaging and were found to lack a cochlear nerve. Twenty-one of 26 (81%) cochlea had some form of dysplasia. Six of 26 (23%) round windows were aplastic. Three of 26 (12%) round windows were hypoplastic. Twenty-one of 26 (81%) oval windows were atretic or aplastic. Fifteen of 26 (58%) vestibules were hypoplastic or dysplastic. There were 5 of 26 (19%) enlarged vestibular aqueducts. Twelve of 26 (46%) vestibular aqueducts had an anomalous course. All cases demonstrated absent semicircular canals. Twenty-three of 26 (88%) facial nerve canals had an anomalous course. Four of 26 (15%) tympanic segments were prolapsed. Three of 26 (12%) temporal bones had an anomalous emissary vein referred to as a petrosquamosal sinus. Twenty-one of 26 (81%) middle ear cavities were small. Twenty-three of 26 (93%) ossicles were dysplastic with ankylosis. Three of 26 (12%) internal auditory canals were small. The CT findings that correlate to the anomalies of CHARGE syndrome affect conductive as well as sensorineural hearing. Stenosis of the aperture for the cochlear nerve aperture on CT is suggestive of hypoplasia or absence of the cochlear nerve, which has been demonstrated in some cases by MR. Absence of the cochlear

    Full Text Available Atrioventricular canal defect (AVCD is a common congenital heart defect (CHD, representing 7.4% of all cardiac malformations, considered secondary to an extracellular matrix anomaly. The AVCD is associated with extracardiac defects in about 75% of the cases. In this review we analyzed different syndromic AVCDs, in particular those associated with polydactyly disorders, which show remarkable genotype-phenotype correlations. Chromo - some imbalances more frequently associated with AVCD include Down syndrome, deletion 8p23 and deletion 3p25, while mendelian disorders include Noonan syndrome and related RASopathies, several polydactyly syndromes, CHARGE and 3C (cranio-cerebello-cardiac syndrome. The complete form of AVCD is prevalent in patients with chromosomal imbalances. Additional cardiac defects are found in patients affected by chromosomal imbalances different from Down syndrome. Left-sided obstructive lesions are prevalently found in patients with RASopathies. Patients with deletion 8p23 often display AVCD with tetralogy of Fallot or with pulmonary valve stenosis. Tetralogy of Fallot is the only additional cardiac defect found in patients with Down syndrome and AVCD. On the other hand, the association of AVCD and tetralogy of Fallot is also quite characteristic of CHARGE and 3C syndromes. Heterotaxia defects, including common atrium and anomalous pulmonary venous return, occur in patients with AVCD associated with polydactyly syndromes (Ellis-van Creveld, short rib polydactyly, oral-facial-digital, Bardet-Biedl, and Smith-Lemli-Opitz syndromes. The initial clinical evidence of anatomic similarities between AVCD and heterotaxia in polydactyly syndromes was corroborated and explained by experimental studies in transgenic mice. These investigations have suggested the involvement of the Sonic Hedgehog pathway in syndromes with postaxial polydactyly and heterotaxia, and ciliary dysfunction was detected as pathomechanism for these disorders

    Paraneoplastic syndromes are rare disorders that are triggered by an altered immune system response to neoplasm. Paraneoplastic syndromes may be the first or the most prominent manifestations of cancer. Wilm's tumor is the most frequent pediatric renal malignancy and usually presents with abdominal mass. Unusual presentations like acquired von Willebrand disease, sudden death due to pulmonary embolism and Cushing syndrome have been described in the literature. Cushing syndrome, as the presenting symptom of a malignant renal tumor in children, is a very rare entity. Few case reports are available in the literature exploring the option of preoperative chemotherapy as well as upfront nephrectomy. We report a rare case of paraneoplastic Cushing syndrome due to a Wilm's tumor. Based on gradual decrease of postoperative weight, blood pressure, serum adrenocorticotropic hormone, and plasma cortisol levels, along with histological confirmation of Wilm's tumor, paraneoplastic Cushing syndrome due to Wilm's tumor was confirmed.

    Acquired stenosis of the external auditory canal (EAC) may occur because of chronic external otitis, recurrent chronic catarrhal otitis media associated with tympanic membrane perforation, chronic dermatitis, tumors, and trauma. Stenosis occurs generally at the one-third bone part of the external auditory canal. In this article, we present 3 cases of acquired EAC stenosis due to the previous powdered boric acid application. Besides the presentation of surgical intervetions in these cases, we want to notify the physicians not to use or carefully use powdered boric acid because of the complication of EAC stenosis.

    BACKGROUND Acute compartment syndrome (ACS) of the thigh after elective primary total knee arthroplasty is rare. If not recognized and treated promptly, devastating consequences may result. Certain regional anesthesia techniques are thought to mask the symptoms of acute compartment syndrome, but there are no cases reported of adductor canal catheters masking the symptoms of thigh compartment syndrome. We report a case where symptoms and diagnosis of acute anterior thigh compartment syndrome were not masked by a functioning adductor canal catheter. CASE REPORT A 56-year-old male developed anterior thigh compartment syndrome after an elective primary total knee arthroplasty. Surgery was performed under spinal anesthesia with periarticular local infiltration analgesia. Postoperatively, an adductor canal catheter was placed, atraumatically, under ultrasound guidance in the recovery room with a plan to begin a continuous infusion of 0.2% ropivacaine 10 hours after the periarticular injection. Six hours after surgery, the patient complained of tightness and 10/10 pain in his right thigh, which was initially managed with parenteral opioids with moderate success. Continuous infusion through the adductor canal catheter was started and pain improved to 6/10 aching pain. Nonetheless, two hours after starting the continuous infusion, the patient reported tightness, swelling, and 10/10 pressure-like pain that was not relieved by the peripheral catheter infusion or PRN boluses of additional opioids. Due to the patient's symptomatology compartment pressures were measured. The anterior compartment pressure was 47 mm Hg and emergent anterior compartment fasciotomy was performed. CONCLUSIONS In this case, a functioning adductor canal catheter did not mask symptoms of, or delay diagnosis of, acute compartment syndrome in the thigh.

    Full Text Available Abstract Background Occupational overuse syndrome (OOS can present as Guyon's canal syndrome in computer keyboard users. We report a case of Guyon's canal syndrome caused by a ganglion in a computer user that was misdiagnosed as OOS. Case presentation A 54-year-old female secretary was referred with a six-month history of right little finger weakness and difficulty with adduction. Prior to her referral, she was diagnosed by her general practitioner and physiotherapist with a right ulnar nerve neuropraxia at the level of the Guyon's canal. This was thought to be secondary to computer keyboard use and direct pressure exerted on a wrist support. There was obvious atrophy of the hypothenar eminence and the first dorsal interosseous muscle. Both Froment's and Wartenberg's signs were positive. A nerve conduction study revealed that both the abductor digiti minimi and the first dorsal interosseus muscles showed prolonged motor latency. Ulnar conduction across the right elbow was normal. Ulnar sensory amplitude across the right wrist to the fifth digit was reduced while the dorsal cutaneous nerve response was normal. Magnetic resonance imaging of the right wrist showed a ganglion in Guyon's canal. Decompression of the Guyon's canal was performed and histological examination confirmed a ganglion. The patient's symptoms and signs resolved completely at four-month follow-up. Conclusion Clinical history, occupational history and examination alone could potentially lead to misdiagnosis of OOS when a computer user presents with these symptoms and we recommend that nerve conduction or imaging studies be performed.

    Full Text Available The use of triple antibiotic paste (TAP (mixture of ciprofloxacin, metronidazole and minocycline as an intra-canal medicament have shown very encouraging results particularly in non-vital immature teeth associated with periradicular lesions. Hence, before opting for a surgical approach, a non-surgical approach can be thought of with extended use of TAP as intra-canal medicament, especially in patients who are phobic to invasive procedures. On the flip side, the use of TAP has few side-effects, of which one is the discoloration it can cause due to the presence of minocycline in the mix. The purpose of this article is to presents a case of coronal discoloration due to the use of TAP as an endodontic intra-canal medicament.

    A 28-year-old female diver presented with dizziness and difficulty clearing her left ear whilst scuba diving. Her pure-tone audiometry and tympanometry were normal. Testing of Eustachian tube function revealed tubal stenosis. Video-oculography revealed a predominantly torsional nystagmus while the patient was in the lordotic position. Fistula signs were positive. High-resolution computed tomography (HRCT) of the temporal bone revealed a diagnosis of bilateral superior semicircular canal dehiscence (SCDS). Cervical vestibular-evoked myogenic potential (cVEMP) testing showed that the amplitude of the cVEMP measured from her left ear was larger than that from the right. In electronystagmography (ENG), nose-pinched Valsalva manoeuvres caused eye movements to be mainly directed counterclockwise with a vertical component. Tullio phenomenon was also positive for both ears. SCDS patients tend to be misdiagnosed and misunderstood; common misdiagnoses in these cases are alternobaric vertigo (AV), inner ear barotrauma, and inner-ear decompression sickness. It is difficult to diagnose vertigo attacks after scuba diving as SCDS; however, when the patient develops sound- and/or pressure-induced vertical-torsional nystagmus, HRCT should be conducted to confirm a diagnosis of SCDS.

    Magnetic resonance imaging (MRI) was undertaken in 26 patients with surgically proven nerve root compression due to lumbar canal stenosis. The findings on coronary images were compared with those of selective radiculography to assess the diagnostic ability of MRI to determine the site of nerve root compression. Intermission and partial defect, which reflect nerve root compression, were seen in only 5 (19.2%) of 26 nerve roots on MRI, as compared with 20 (76.9%) on radiculography. Thus MRI alone was difficult to diagnose nerve root compression due to lumbar canal stenosis. Furthermore, the optimum angle of coronary views was determined in 13 cadavers. Para-sagittal views were found to be optimal for the observation of the whole running of the nerve root. Three-dimensional MRI was found to have a potential to diagnose nerve root compression in the intervertebral foramen and the distal part of the intervertebral foramen. (N.K.).

    Correlation between magnetic resonance imaging (MRI) and clinical features in cauda equina syndrome (CES) is unknown; nor is known whether there are differences in MRI spinal canal size between lumbar herniated disc patients with CES versus lumbar herniated discs patients without CES, operated for sciatica. The aims of this study are 1) evaluating the association of MRI features with clinical presentation and outcome of CES and 2) comparing lumbar spinal canal diameters of lumbar herniated disc patients with CES versus lumbar herniated disc patients without CES, operated because of sciatica. MRIs of CES patients were assessed for the following features: level of disc lesion, type (uni- or bilateral) and severity of caudal compression. Pre- and postoperative clinical features (micturition dysfunction, defecation dysfunction, altered sensation of the saddle area) were retrieved from the medical files. In addition, anteroposterior (AP) lumbar spinal canal diameters of CES patients were measured at MRI. AP diameters of lumbar herniated disc patients without CES, operated for sciatica, were measured for comparison. 48 CES patients were included. At MRI, bilateral compression was seen in 82%; complete caudal compression in 29%. MRI features were not associated with clinical presentation nor outcome. AP diameter was measured for 26 CES patients and for 31 lumbar herniated disc patients without CES, operated for sciatica. Comparison displayed a significant smaller AP diameter of the lumbar spinal canal in CES patients (largest p = 0.002). Compared to average diameters in literature, diameters of CES patients were significantly more often below average than that of the sciatica patients (largest p = 0.021). This is the first study demonstrating differences in lumbar spinal canal size between lumbar herniated disc patients with CES and lumbar herniated disc patients without CES, operated for sciatica. This finding might imply that lumbar herniated disc patients with a

The aims of this study are 1 evaluating the association of MRI features with clinical presentation and outcome of CES and 2 comparing lumbar spinal canal diameters of lumbar herniated disc patients with CES versus lumbar herniated disc patients without CES, operated because of sciatica.MRIs of CES patients were assessed for the following features: level of disc lesion, type (uni- or bilateral and severity of caudal compression. Pre- and postoperative clinical features (micturition dysfunction, defecation dysfunction, altered sensation of the saddle area were retrieved from the medical files. In addition, anteroposterior (AP lumbar spinal canal diameters of CES patients were measured at MRI. AP diameters of lumbar herniated disc patients without CES, operated for sciatica, were measured for comparison.48 CES patients were included. At MRI, bilateral compression was seen in 82%; complete caudal compression in 29%. MRI features were not associated with clinical presentation nor outcome. AP diameter was measured for 26 CES patients and for 31 lumbar herniated disc patients without CES, operated for sciatica. Comparison displayed a significant smaller AP diameter of the lumbar spinal canal in CES patients (largest p = 0.002. Compared to average diameters in literature, diameters of CES patients were significantly more often below average than that of the sciatica patients (largest p = 0.021.This is the first study demonstrating differences in lumbar spinal canal size between lumbar herniated disc patients with CES and lumbar herniated disc patients without CES, operated for sciatica. This finding might imply that lumbar herniated disc patients with

    Although formaldehyde is well known to cause type 4 hypersensitivity, immunoglobulin E (IgE)-mediated hypersensitivity to formaldehyde is rare. Here, we report a case of recurrent generalized urticaria after endodontic treatment using a para-formaldehyde (PFA)-containing root canal sealant and present a review of previous studies describing cases of immediate hypersensitivity reactions to formaldehyde. A 50-year-old man visited our allergy clinic for recurrent generalized urticaria several hours after endodontic treatment. Prick tests to latex, lidocaine, and formaldehyde showed negative reactions. However, swelling and redness at the prick site continued for several days. The level of formaldehyde-specific IgE was high (class 4). Thus, the patient was deemed to have experienced an IgE-mediated hypersensitivity reaction caused by the PFA used in the root canal disinfectant. Accordingly, we suggest that physicians should pay attention to type I hypersensitivity reactions to root canal disinfectants, even if the symptoms occur several hours after exposure.

    Full Text Available Background Lacunar syndrome not due to lacunar infarct is poorly characterised. This single centre, retrospective study was conducted to describe the clinical characteristics of patients with lacunar syndrome not due to lacunar infarct and to identify clinical predictors of this variant of lacunar stroke. Methods A total of 146 patients with lacunar syndrome not due to lacunar infarction were included in the "Sagrat Cor Hospital of Barcelona Stroke Registry" during a period of 19 years (1986-2004. Data from stroke patients are entered in the stroke registry following a standardized protocol with 161 items regarding demographics, risk factors, clinical features, laboratory and neuroimaging data, complications and outcome. The characteristics of these 146 patients with lacunar syndrome not due to lacunar infarct were compared with those of the 733 patients with lacunar infarction. Results Lacunar syndrome not due to lacunar infarct accounted for 16.6% (146/879 of all cases of lacunar stroke. Subtypes of lacunar syndromes included pure motor stroke in 63 patients, sensorimotor stroke in 51, pure sensory stroke in 14, atypical lacunar syndrome in 9, ataxic hemiparesis in 5 and dysarthria-clumsy hand in 4. Valvular heart disease, atrial fibrillation, sudden onset, limb weakness and sensory symptoms were significantly more frequent among patients with lacunar syndrome not due to lacunar infarct than in those with lacunar infarction, whereas diabetes was less frequent. In the multivariate analysis, atrial fibrillation (OR = 4.62, sensorimotor stroke (OR = 4.05, limb weakness (OR = 2.09, sudden onset (OR = 2.06 and age (OR = 0.96 were independent predictors of lacunar syndrome not due to lacunar infarct. Conclusions Although lacunar syndromes are highly suggestive of small deep cerebral infarctions, lacunar syndromes not due to lacunar infarcts are found in 16.6% of cases.

    2017-12-14

    Superior canal dehiscence syndrome (SCDS) is a relatively rare neurotological disorder that is characterized by a heterogeneous clinical picture. Recently, vestibular evoked myogenic potential (VEMP) measurement was established for the diagnosis of SCDS. In the present study, a case series of patients with SCDS were analyzed, with a focus on VEMP. Four patients with SCDS were prospectively examined with ocular VEMP (oVEMP) and cervical VEMP (cVEMP). The clinical features and the standard audiovestibular test battery results are summarized and analyzed. The diagnostic accuracy of VEMP testing is evaluated. The increased oVEMP amplitudes had a specificity of 100% in this patient population. All patients had normal caloric function and head impulse testing. The Tullio sign was observed in two patients. Three patients had autophony. The air-bone gap was not greater than 10 dB in any of the patients. Two patients had marked fremitus nystagmus. All patients had a bony dehiscence of the superior semicircular canal on computed tomography imaging. The subjective and clinical features in this case series of SCDS patients were heterogeneous. However, objective oVEMP testing had the highest diagnostic value. Furthermore, we describe a new diagnostic clinical sign: fremitus nystagmus.

    In a consecutive series of 600 patients scanned by CT for various spinal diseases, those with low back and sciatic pain without disc herniation were selected for study. The causes proved to be joint facet degeneration (32 cases), stenosis of the neural foramina (13 cases), stenosis of the spinal canal (13 cases), lateral recess stenosis (6 cases) and spondylolisthesis (6 cases). The predominance of joint fact pathology as the underlying cause of low back and sciatic pain in the absence of disc herniation is confirmed. CT scanning of the soft tissues as well as of the skeletal structures is crucial to the aetiological diagnosis of the condition under study and hence to the proper planning of treatment.

    Le syndrome du canal carpien (SCC) regroupe l'ensemble des signes et symptômes liés à la compression du nerf médian dans le canal carpien. Cette manifestation de l'amylose à béta2-microglobuline est une complication fréquente de l'hémodialyse au long cours. L'objectif de ce travail est d'analyser les caractéristiques du SCC et de déterminer les facteurs liés à sa survenue chez les hémodialysés chroniques. Nous rapportons une étude transversale monocentrique, menée au 3ème trimestre de l'année 2009, portant sur les patients adultes hémodialysés chroniques au service de Néphrologie-Hémodialyse au CHU de Fès. 59 patients ont accepté de participer à l'étude. Leurs âge moyen est de 48 ± 15 ans avec un sex-ratio de 0,9. Ils bénéficient tous de l'hémodialyse intermittente à raison de 10 à 12 heures par semaine, par une membrane de dialyse en polysulfone à basse perméabilité. La durée moyenne en hémodialyse est de 83 ± 6,5 mois. La prévalence du SCC dans notre centre est de 30,5%. L'électromyogramme (EMG) a confirmé la suspicion clinique du SCC chez 11 patients et a diagnostiqué un SCC chez 8 patients asymptomatiques. La comparaison statistique entre les deux groupes de patients avec et sans SCC a démontré que la survenue de ce syndrome est liée à: l'âge actuel, l'âge avancé à la mise en hémodialyse, le sexe féminin, l'excès pondéral, et l'abord vasculaire. Le SCC est une complication fréquente de l'hémodialyse chronique. L'amélioration de la qualité de dialyse permettrait de réduire le risque de survenue du SCC. PMID:23504584

    2018-02-01

    Superior Canal Dehiscence Syndrome (SCDS) causes auditory and vestibular symptoms. Following surgical repair of the dehiscence, patients often experience dizziness and imbalance. This case report describes a postoperative vestibular exercise program, focusing on the principles of central compensation and habituation, and how it was modified for a patient with delayed progress secondary to strabismus and visual vertigo. A 63-year-old male with history of strabismus eye surgery, right hearing loss, aural fullness, and sensitivity to loud sounds was referred for vestibular rehabilitation (VR). He was seen for one preoperative and six postoperative PT visits over eight months. Outcome measures two weeks postoperative were as follows: Dizziness Handicap Inventory (DHI) 38/100; Timed Up & Go (TUG) 9.92 seconds; Dynamic Gait Index (DGI) 16/24; and a 3-line difference in Dynamic Visual Acuity (DVA). Improved outcomes at discharge included: DHI 18/100; TUG 6.87 seconds; DGI 23/24; and 1-line difference in DVA. He was able to return to work and previously enjoyed recreational activities. Postoperative vestibular rehabilitation programs are functionally and symptomatically beneficial following surgical repair for SCDS. Deviations from expected recovery should be addressed to achieve optimal outcomes as demonstrated in this complicated case report.

    2009-12-01

    This article offered an extensive description of the clinical and pathological features and time-course of the skin manifestations of toxic syndrome caused by denatured rapeseed oil, also known as toxic oil syndrome. This new condition occurred in Spain in 1981 and was due to the ingestion of rapeseed oil intended for industrial use that had been denatured with anilines and subsequently refined and sold fraudulently as olive oil. In total, 20,000 cases and 400 deaths were reported. The disease affected mainly women, particularly in the late stages. In the acute phase, the predominant skin manifestations were toxic-allergic rashes reminiscent of allergic urticaria in the dermatopathologic study. In approximately 25% of cases, the patients' skin subsequently took on an edematous appearance, with pigmentary abnormalities shown to be related to cutaneous mucinosis. Finally, a characteristic sclerodermatous condition would develop that tended to improve spontaneously. The constant presence of mast cells in all biopsies and the development of mastocytosis in several patients pointed to an important role for these cells in the pathogenesis of the condition. This was subsequently confirmed in other sclerodermatous processes. In 1989, eosinophilia-myalgia syndrome caused by toxins present in tryptophan food supplements was reported in the United States. This syndrome resembled toxic oil syndrome in many ways and demonstrated that mucinosis and toxic sclerodermatous processes do exist.

    Emanuel syndrome is an inherited chromosomal abnormality resulting from 3:1 meiotic segregation from parental balanced translocation carrier t(11;22)(q23;q11), mostly of maternal origin. It is characterized by mental retardation, microcephaly, preauricular tag or sinus, ear anomalies, cleft or high arched palate, micrognathia, congenital heart diseases, kidney abnormalities, structural brain anomalies and genital anomalies in male. Here in, we describe a female patient with supernumerary der(22) syndrome (Emanuel syndrome) due to balanced translocation carrier father t(11;22) (q23;q11). She was mentally and physically disabled and had most of the craniofacial dysmorphism of this syndrome. Our patient had cleft palate, maldeveloped corpus callosum and hind brain with normal internal organs. Additionally, arachnodactyly, hyperextensibility of hand joints, abnormal deep palmar and finger creases, extra finger creases and bilateral talipus were evident and not previously described with this syndrome. Cytogenetic analysis and FISH documented that the patient had both translocation chromosomes plus an additional copy of der(22) with karyotyping: 47,XX,t(11; 22)(q23;q11),+der(22)t(11;22)(q23;q11). We postulated that this rare chromosomal complement can arise from; 2:2 segregation in the first meiotic division of the balanced translocation father followed by non-disjunction at meiosis II in the balanced spermatocyte.

    Full Text Available BACKGROUND Although pulmonary tuberculosis is a common disease in India, tuberculosis of right middle lobe is infrequent. Tuberculosis of the right middle lobe leading to chronic collapse is a cause of Right Middle Lobe syndrome. METHODS The patients attended Pulmonary Medicine Outdoor at Era’s Lucknow Medical College, Lucknow from April 2015 to March 2016. The purpose of this study is to describe the clinicoradiological features of patients of middle lobe syndrome due to tuberculosis. All patients presented with cough with or without expectoration, fever, chest pain, haemoptysis and constitutional symptoms like loss of appetite and weight. Chest X-ray PA view revealed ill-defined opacity abutting the right cardiac border. HRCT thorax was done in each case. The diagnosis of tuberculous aetiology was based on (1 History of chronic cough and fever, not responding to antibiotic therapy and constitutional symptoms, (2 A positive tuberculin test using 2 TU of PPD RT 23 and (3 Detection of acid fast bacilli by direct smear or Mycobacterium tuberculosis by polymerase chain reaction in bronchoalveolar lavage. RESULTS Out of 10 patients, 4 (40% were males and 6 (60% were females. The mean ages of the males were 55.8 years and females were 60.8 years and overall mean age was 59 years. Most of the patients were females and belonged to the middle age and old age group. ATT was started in all the patients. CONCLUSIONS Right middle lobe syndrome predominantly affects the older population and the female gender. Although tuberculosis is a common disease in India, Middle Lobe Syndrome is a very rare presentation of the disease. Due to non-specific symptoms and usually normal chest X-ray PA view in Right Middle Lobe Syndrome, we should keep a high index of suspicion to diagnose the condition.

    Herlyn-Werner-Wunderlich syndrome is a congenital urogenital malformation that is associated with a uterus didelphys and a longitudinal vaginal septum, resulting in a blind hemivagina and ipsilateral renal agenesis. Clinical presentation is highly variable, delaying diagnosis and leading to important complications. We present the case of a 13-year-old female who was diagnosed with Herlyn-Werner-Wunderlich syndrome following an acute abdomen due to a right tubo-ovarian abscess. She had a vaginal septum giving rise to a right blind hemivagina. It was microperforated, causing intermittent genital bleeding. This hematocolpos was colonized by microorganisms that ascended to the pelvic cavity, causing right tuboovarian abscess. Nuclear magnetic resonance imaging provided theWernermost diagnostic information. We performed a vaginal septum resection, and both hemiuteros communicated with a single vagina, resulting in an asymptomatic patient. Herlyn-Werner-Wunderlich syndrome is a little known entity and can be presented atypically, resulting in diagnostic difficulty and treatment delay. It is important to be aware of this syndrome in order to avoid irreversible complications.

    To report a case of an interaction between inhaled corticosteroids and itraconazole causing iatrogenic Cushing's syndrome and provide a review of the relevant literature. A 70-year-old white woman on long-term treatment with high-dose inhaled corticosteroids for asthma was diagnosed as having Scedosporium apiospermum infection of the skin and subcutaneous tissues. As a result, she was treated with itraconazole for 2 months. She subsequently developed Cushing's syndrome due to a probable cytochrome P450-mediated interaction between itraconazole and budesonide. She also had secondary adrenal insufficiency requiring prolonged treatment with replacement hydrocortisone. Budesonide is a potent glucocorticoid that is metabolized in the liver by the CYP3A4 isoenzyme to inactive metabolites. Itraconazole is a potent cytochrome P450 inhibitor. It can inhibit the metabolism of oral or inhaled corticosteroids, producing cortisol excess leading to Cushing's syndrome and adrenal insufficiency. An assessment of causality indicated a possible adverse interaction between itraconazole and budesonide. The combination of itraconazole and inhaled corticosteroids is increasingly being used to treat conditions such as allergic bronchopulmonary aspergillosis. Clinicians need to be aware of the potential for an interaction between such a combination.

    1999-11-01

    We describe a method for diagnosing dural ectasia (DE) and spinal canal widening (SCW) using CT. We examined 23 patients with Marfan's syndrome (MFS), 17 with Ehlers-Danlos syndrome (EDS) and 29 normal subjects, using six axial slices at the level of the L1-S1 pedicles. Transverse diameters of the vertebral bodies, spinal canal and dural sac were measured and indices were defined to differentiate patients with DE and SCW from normal. Statistical significance was assessed using Student's t -test, {chi} {sup 2}-test and Pearson's correlation coefficient. DE and SCW occurred in 69.6 % and 60.9 % of cases of MFS and in 23.5 % and 35.3 % of EDS respectively. In MFS, prevalence was significantly higher than in the control group. DE was significantly more frequent in MFS than in EDS. A strong correlation existed between DE and SCW in MFS and the control group, but not in EDS. Our system enables quantitative assessment of SCW and DE. The latter is particularly important in subjects suspected of having MFS, in whom it is a common and characteristic sign. (orig.)

    Butler, Merlin G

    2011-01-01

    Prader-Willi syndrome (PWS) is a complex neurodevelopmental disorder due to errors in genomic imprinting with loss of imprinted genes that are paternally expressed from the chromosome 15q11-q13 region. Approximately 70% of individuals with PWS have a de novo deletion of the paternally derived 15q11-q13 region in which there are two subtypes (i.e., larger Type I or smaller Type II), maternal disomy 15 (both 15s from the mother) in about 25% of cases, and the remaining subjects have either defects in the imprinting center controlling the activity of imprinted genes or due to other chromosome 15 rearrangements. PWS is characterized by a particular facial appearance, infantile hypotonia, a poor suck and feeding difficulties, hypogonadism and hypogenitalism in both sexes, short stature and small hands and feet due to growth hormone deficiency, mild learning and behavioral problems (e.g., skin picking, temper tantrums) and hyperphagia leading to early childhood obesity. Obesity is a significant health problem, if uncontrolled. PWS is considered the most common known genetic cause of morbid obesity in children. The chromosome 15q11-q13 region contains approximately 100 genes and transcripts in which about 10 are imprinted and paternally expressed. This region can be divided into four groups: 1) a proximal non-imprinted region; 2) a PWS paternal-only expressed region containing protein-coding and non-coding genes; 3) an Angelman syndrome region containing maternally expressed genes and 4) a distal non-imprinted region. This review summarizes the current understanding of the genetic causes, the natural history and clinical presentation of individuals with PWS. PMID:22043168

    A 1-year-old sexually intact male Korat cat was referred for ophthalmological consultation due to anisocoria. Mydriasis with external ophthalmoplegia and absence of pupillary light responses in the right eye and nasofacial hypalgesia were seen. Cavernous sinus syndrome (CSS) was suspected. Bilateral deformities of the jaw and phalangeal bones, severe spinal pain and abnormal conformation of the lumbar spine were also present. Radiographic examination revealed several mineralised masses in the appendicular and axial skeleton, indicative of multiple cartilaginous exostoses. For further investigation of the CSS-related neurological deficits, the cat underwent computed tomography (CT) examination of the skull. CT images revealed a non-vascularised, calcified, amorphous mass originating from the right lateral skull base and superimposing on the sella turcica. Based on the severity of diffuse lesions and owing to the clinical signs of extreme pain, the cat was euthanased. A diffuse skeletal and intracranial osteochondromatosis was diagnosed histologically.

    Full Text Available Introduction: We report a case of acute adrenal insufficiency (AAI in a patient with antiphospholipid syndrome (APS. Case Report: A 44-year-old female patient presented to us with acute abdominal pain associated with recurrent vomiting and giddiness. On examination, her blood pressure was 80/50 mm Hg. Systemic examination was normal. Further evaluation revealed hypocortisolemia with elevated plasma adrenocorticotropin hormone indicative of primary adrenal insufficiency. Her abdominal computed tomography scan showed features of evolving bilateral adrenal infarction. Etiological work-up revealed prolonged activated thromboplastin time, which didn′t correct with normal plasma, her anti-cardiolipin antibody and lupus anticoagulant were also positive. She was diagnosed to have APS with adrenal insufficiency and she was started on intravenous steroids and heparin infusion. Conclusion: AAI due to the APS can present with acute abdominal pain followed by hypotension. A high index of suspicion is needed to make the correct diagnosis and to initiate appropriate treatment.

    We have reported a very rare case of a patient with callosal disconnection syndrome due to acute disseminated enchephalomyelitis (ADEM). A 54-year-old right-handed woman developed sudden consciousness disturbance and fever after 2 weeks when she had common cold. She did not have a history of stuttering. On admission, the neurological finding showed consciousness disturbance, and exaggerated muscle stretch reflex in four extremities without meningeal irritation. The cerebrospinal fluid examination revealed the cell counts of 273/mm3, the protein of 348 mg/dl and the myelin basic protein 18.3 pg/ml. The brain MRI demonstrated a focal high signal intensity in the right cerebellar peduncle, right temporal lobe, left occipital lobe and corpus callosum on the T2-weighted and FLAIR images. The lesion of corpus callosum was the trunk and splenium, sparing the dorsal side of splenium. Her diagnosis was ADEM. The steroid pulse therapy (metylpredinisolone 1 g/day for 3 days) improved the consciousness disturbance. After 6 weeks from the onset, the neuropsycological examination was performed. The remarkable findings included pure alexia without color naming defects, the acquired stuttering and one-way disturbance of somesthetic transfer from the left hand to the right. This patient may contribute to the study of functional localization of the corpus callosum.

    Full Text Available We report a rare case of ulnar nerve entrapment caused by a synovial cyst derived from the left elbow joint. A 57-year-old male patient with a seven-month history of pain in his left elbow and a progressive and increasing numbness and weakness complaints in his left hand came to our clinic. Weakness and sensory loss of the 4th and 5th fingers were determined in neurological examination. The results of Tinel’s sign and Phalen’s Test were positive, especially when his left elbow was flexed. In electromyelography, axonal damage and entrapment neuropathy were determined in the left cubital tunnel area. Total excision of the synovial cyst and ulnar nerve anterior subcutaneous transposition were performed in surgical treatment. The patient’s pain decreased immediately after the surgery. In this report, we have discussed the pathopysiology of cubital tunnel syndrome due to synovial cyst and which surgical technique may be suitable as our case report.

    Overuse and acute injuries to the upper body are common in rock climbing. Such injuries primarily affect the fingers; but shoulder problems are increasingly common, especially among more experienced and older climbers who climb at a high ability level. Such shoulder problems are often due to subacromial impingement, shoulder dislocations with bankart lesions, hyperlaxity, SLAP lesions or irritations of the long biceps tendon. In contrast to these known conditions, we describe a case of an ambitious female rock climber who trained intensively and developed a coracoid impingement caused by hypertrophied subscapularis tendon and muscle following sport-specific training. Diagnosis was made through clinical evaluation and confirmed by magnetic resonance tomography. Coracoid impingement syndrome is a less common cause of shoulder pain and occurs when the subscapularis tendon impinges between the coracoid and the lesser tuberosity of the humerus. The patient was treated successfully with a conservative therapy and returned to full activity within 6 weeks. Copyright © 2011 Wilderness Medical Society. Published by Elsevier Inc.

    Iatrogenic Cushing's syndrome (CS) is a severe adverse effect of systemic glucocorticoid (GC) therapy in children, but is extremely rare in the setting of topical ocular GC therapy. In this article, we report the case of a 9-year-old girl suffering from idiopathic uveitis who developed CS due to topical ocular GC treatment. She was referred to the ophthalmology department with a complaint of painful eyes, at which time she was diagnosed with bilateral iridocyclitis and started on a treatment of betamethasone sodium phosphate eye drops. Six months after the initiation of topical ocular GC treatment, she was referred to our pediatric department with stunted growth, truncal obesity, purple skin striate, buffalo hump, and moon face. Because her serum cortisol and plasma adrenocorticotropic hormone levels were undetectable, she was diagnosed with iatrogenic CS. After the doses of topical ocular GC were reduced, the clinical symptoms of CS were improved. The fact that the amount of topical ocular GC with our patient was apparently less than that of similar previous cases tempted us to perform genetic analysis of her NR3C1 gene. We found that our patient had a single heterozygous nucleotide substitution in the 3' untranslated region of the NR3C1 gene, which may explain why she developed CS. However, additional investigations are required to determine if our findings can be extrapolated to other patients. In conclusion, clinicians should be aware that even extremely low doses of topical ocular steroid therapy can cause iatrogenic CS. Copyright © 2017 by the American Academy of Pediatrics.

    2017-12-18

    A 12-y-old boy presented with developmental delay, autism, epilepsy, limb tremors and behavioral problems which posed a diagnostic challenge. Though his clinical profile and electroencephalogram were suggestive of Angelman syndrome, initial genetic tests were unyielding. Exome sequencing revealed a previously unreported mutation of Ubiquitin Protein Ligase E3A (UBE3A) gene, confirming the diagnosis of Angelman syndrome. The case is aimed to sensitize pediatricians about Angelman syndrome and to highlight the role of sequential investigations in establishing the diagnosis.

    2013-02-01

    Full Text Available Envenoming syndrome from Africanized bee stings is a toxic syndrome caused by the inoculation of large amounts of venom from multiple bee stings, generally more than five hundred. The incidence of severe toxicity from Africanized bee stings is rare but deadly. This report reveals that because of the small volume of distribution, having fewer stings does not exempt a patient from experiencing an unfavorable outcome, particularly in children, elderly people or underweight people.

    2017-01-01

    We sought to establish whether the increased incidence of diabetes associated with Down syndrome was due to a congenital deficit in β cells. The pancreas was obtained at autopsy from nondiabetic subjects with Down syndrome (n = 29) and age-matched nondiabetic control subjects without Down syndrome (n = 28). The pancreas sections were evaluated for the fractional β-cell area. No difference was found in the fractional β-cell area between the subjects with Down syndrome and the control subjects. The increased incidence and prevalence of diabetes in individuals with Down syndrome is not due to an underlying congenital deficiency of β cells.

    2017-01-01

    Compartment syndrome is an orthopedic emergency with a multitude of etiologies. Although it is most commonly associated with trauma to the extremity, hematoma and infection are 2 rare etiologies of insidious compartment syndrome. Proteus mirabilis is an opportunistic gram-negative species that can infect the respiratory tract, urinary tract, and open wounds. The authors present the case of a 69-year-old woman who developed tissue necrosis and compartment syndrome secondary to an untreated hematoma infected by P mirabilis. This case involves an atypical presentation caused by an untreated infected hematoma, emphasizing the need for a high index of suspicion. Current literature supports immediate surgical intervention in the clinical scenario of fulminant compartment syndrome, regardless of compartment pressure findings. The probability of compartment syndrome in the patient presenting with pain, paresthesias, paresis, and pain with passive stretch, all of which were positive findings in this patient, has been reported to be 98%. Thus, Doppler evaluation and intercompartmental pressures were considered but forgone to expedite operative treatment. Emergent 4-compartment fasciotomies, with excision and debridement of nonviable tissue, are potentially limb-saving procedures, intended to limit loss of function and obviate the need for lower extremity amputation. The decision was made to perform a dual-incision fasciotomy to avoid contamination of the uninvolved compartments with a standard single-incision approach. To date, this represents the first report in the English literature of the insidious onset of tissue necrosis secondary to a Proteus-infected hematoma, highlighting a unique etiology of atypical compartment syndrome.

    Full Text Available Serotonin syndrome is a drug side effect resulting from serotonergic hyperactivity. The severity of its symptoms can be mild and overlooked and sometimes it may cause life-threatening serious consequences. This syndrome is caused by the administration of one or more drugs having serotonergic activity. This case is a 25-year-old female patient who attempted suicide by ingesting an overdose of her prescription medications: 60 units of 100-mg Faver (Fluvoxamine, 20 units of 50-mg Setral (Setraline, and 10 units of 20-mg Paxil (Paroxetine.

    Full Text Available Abstract Background Scrub typhus, a mite-transmitted zoonosis caused by Orientia tsutsugamushi, is an endemic disease in Taiwan and may be potentially fatal if diagnosis is delayed. Case presentations We encountered a 23-year-old previously healthy Taiwanese male soldier presenting with the right ear pain after training in the jungle and an eleven-day history of intermittent high fever up to 39°C. Amoxicillin/clavulanate was prescribed for otitis media at a local clinic. Skin rash over whole body and abdominal cramping pain with watery diarrhea appeared on the sixth day of fever. He was referred due to progressive dyspnea and cough for 4 days prior to admission in our institution. On physical examination, there were cardiopulmonary distress, icteric sclera, an eschar in the right external auditory canal and bilateral basal rales. Laboratory evaluation revealed thrombocytopenia, elevation of liver function and acute renal failure. Chest x-ray revealed bilateral diffuse infiltration. Doxycycline was prescribed for scrub typhus with acute respiratory distress syndrome and multiple organ failure. Fever subsided dramatically the next day and he was discharged on day 7 with oral tetracycline for 7 days. Conclusion Scrub typhus should be considered in acutely febrile patients with multiple organ involvement, particularly if there is an eschar or a history of environmental exposure in endemic areas. Rapid and accurate diagnosis, timely administration of antibiotics and intensive supportive care are necessary to decrease mortality of serious complications of scrub typhus.

  10. Complete atrioventricular canal

    Full Text Available Abstract Complete atrioventricular canal (CAVC, also referred to as complete atrioventricular septal defect, is characterised by an ostium primum atrial septal defect, a common atrioventricular valve and a variable deficiency of the ventricular septum inflow. CAVC is an uncommon congenital heart disease, accounting for about 3% of cardiac malformations. Atrioventricular canal occurs in two out of every 10,000 live births. Both sexes are equally affected and a striking association with Down syndrome was found. Depending on the morphology of the superior leaflet of the common atrioventricular valve, 3 types of CAVC have been delineated (type A, B and C, according to Rastelli's classification. CAVC results in a significant interatrial and interventricular systemic-to-pulmonary shunt, thus inducing right ventricular pressure and volume overload and pulmonary hypertension. It becomes symptomatic in infancy due to congestive heart failure and failure to thrive. Diagnosis of CAVC might be suspected from electrocardiographic and chest X-ray findings. Echocardiography confirms it and gives anatomical details. Over time, pulmonary hypertension becomes irreversible, thus precluding the surgical therapy. This is the reason why cardiac catheterisation is not mandatory in infants (less than 6 months but is indicated in older patients if irreversible pulmonary hypertension is suspected. Medical treatment (digitalis, diuretics, vasodilators plays a role only as a bridge toward surgery, usually performed between the 3rd and 6th month of life.

    Full Text Available Cavernous hemangiomas are the most common benign tumors of the liver. They can reach enormous sizes and cause various complications. Kasabach-Merritt syndrome is a rare but serious complication characterized by consumptive coagulopathy caused by the hemangioma; mortality rate ranges between 10 and 37%. More than 80% of cases occur within the first year of life. Goals of the treatment are to control the coagulopathyand thrombocytopenia as well as to eradicate the hemangioma. Different nonsurgical treatment regimens are performed, includingsystemic corticosteroids, irradiation and various chemicals. Surgery should be limited to symptomatic or complicated cases. Although difficult, resection of the tumor is usually curative. Here we present a 44-year-old woman with giant hepatic hemangioma causing Kasabach-Merritt syndrome managed by enucleation.

  12. Renal tubular acidosis due to the milk-alkali syndrome.

    1977-06-01

    A 60-year-old man with a history of excessive ingestion of calcium carbonate presented with azotemia, hypercalcemia and hyperphosphatemia. His acid-base status was initially normal. Following the cessation of calcium carbonate treatment, the hypercalcemia and azotemia disappeared, and the patient was found to be in metabolic acidosis with blunted acid excretion and a urine pH of 6.1. Kidney biopsy showed focal tubular calcification; the tubular damage was apparently caused by hypercalcemia and had resulted in renal tubular acidosis. During the three months of observation since that time there has been a tendecy for spontaneous remission of the renal tubular acidosis. Impaired renal hydrogen ion excretion prevented the development of metabolic alkalosis despite ingestion of alkali initially, and was later responsible for the metabolic acidosis. Renal tubular acidosis occurring as a sequel to the milk-alkali syndrome may aggravate the danger of nephrocalcinosis in this syndrome.

    2013-07-01

    Trigeminal neuralgia (TN) is a common pain in the orofacial region. Dandy-Walker syndrome (DWS) is a congenital malformation of the cerebellar and the fourth ventricle foramina atresia. Dandy-Walker syndrome is rarely found in patients with TN. This article presents a 36-year-old man with the symptoms of typical TN. His physical examination was entirely normal. An enhanced magnetic resonance imaging was taken. Magnetic resonance imaging revealed the bilateral lateral ventricle, the fourth and third ventricle significantly enlarged with severe obstructive hydrocephalus, a huge posterior fossa cyst connected with the fourth ventricle, and hypoplastic vermis. The pain was controlled by Tegretol. The reported case suggests that DWS is an unusual cause of TN.

    Despite the widespread medical use of glucocorticoids, reports of factitious administration of these hormones have been uncommon. We herein report an outbreak of Cushing's syndrome in Tehran among the addicts using Tamgesic (a brand of Buprenorphine) to help them through the narcotic withdrawal stage, without knowledge of the glucocorticoid content of the black-market drug. Case histories of 19 patients with a final diagnosis of iatrogenic Cushing's syndrome were reviewed. Liquid chromatography/mass spectrometry (LC-Mass) method was used to evaluate glucocorticoid existence in the brand. High performance liquid chromatography was used to determine plasma dexamethasone level. No buprenorphine was present in the vials. Each Tamgesic vial contained 0.4 mg of Dexamethasone disodium phosphate; Heroin was also found in them. The duration of injection abuse and the total dexamethasone intake was 4.5 (1-18) months and 2.6 (0.8-8) mg/day, respectively. Median plasma dexamethasone concentration was 5.8 nmol/l, with a range of 5-8.7. Physical findings of the cases were not different from those of the classic endogenous Cushing's syndrome but their serum cortisol and urinary free cortisol were suppressed. Severe life-threatening complications were demonstrated in five cases. Surreptitious use of steroids resulting in Cushing's syndrome may be more common in opium addicts; a high degree of suspicion is needed to uncover this disorder. Whenever facing a cushingoid appearance in addicts, the possibility of using black market drugs with corticosteroid contents should be kept in mind.

  16. West syndrome due to vitamin B12 deficiency.

    Serin, Hepsen Mine; Kara, Aslıhan Oruçoğlu; Oğuz, Baran

    2015-12-01

    Vitamin B12 is one of the essential vitamins affecting various systems of the body. Vitamin B12 deficiency in infants often produces haematological and neurological deficits including macrocyticanaemia, neurodevelopmental delay or regression, irritability, weakness, hypotonia, ataxia, apathy, tremor andseizures. In this article, we report the case of a six-month-old male patient diagnosed with West syndrome associated with vitamin B12 deficiency. Although the patient had no evidence of macrocytic anemia in complete blood count, we measured the level of vitamin B12 because the patient had hypotonicity and found it to be low. No other problem was found in the other investigations directed to the etiology of West syndrome. He was being exclusively breast-fed and vitamin B12 deficiency was related with nutritional inadequacy of his mother. Vitamin B12 deficiency should be considered in the differential diagnosis of patients presenting with different neurological findings. In addition, vitamin B12 deficiency should be considered as a rare cause in West syndrome which has a heterogeneous etiology.

    Migrainous infarction accounts for 12.8% of ischemic strokes of unusual etiology. A 59-year-old woman with longstanding migraine with aura experienced what appeared to be migrainous infarction characterized by dysmetropsia and transient Cotard's syndrome. Imaging demonstrated right temporal-parietal-occipital changes with apparent cortical laminar necrosis. The spectrum of the pathophysiology of migrainous infarction has not been established; however, cortical spreading depression may explain the appearance of imaging findings that do not obey a vascular territory. © International Headache Society 2014 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

    Full Text Available An 82-year-old male, a known case of severe osteoporosis with vertebral fracture and prostatic carcinoma, was treated with gonadotropin releasing hormone analogue, calcium carbonate, cholecalciferol sachet and injection teriparatide. His diet consisted of milk and curd. He developed altered behavior and generalized weakness, and on investigation, hypercalcemia, hypokalemia, and metabolic alkalosis with low parathyroid hormone levels were detected. Injection teriparatide was stopped and he was managed with forced saline diuresis and injection zoledronic acid. He was diagnosed as a case of milk alkali syndrome in whom teriparatide and prolonged immobilization played a permissive role in the development of hypercalcemic encephalopathy.

  19. Severe Hypoglycemic Coma due to Insulin Autoimmune Syndrome

    Directory of Open Access Journals (Sweden)

    Wen-Ya Ma

    2005-02-01

    Full Text Available Insulin autoimmune syndrome, characterized by the presence of insulin-binding autoantibodies and fasting or late postprandial hypoglycemia, is a rare cause of hypoglycemia. We report a patient with pulmonary tuberculosis who developed recurrent spontaneously post-absorptive hyperinsulinemic hypoglycemia after treatment with anti-tuberculous drugs. Imaging studies of the pancreas were unremarkable, and selective intra-arterial calcium stimulation with hepatic venous sampling for insulin failed to show a gradient, thus almost completely excluding the possibility of occult insulinoma or nesidioblastosis. Examinations of sera, however, disclosed a high titer of polyclonal insulin-binding autoantibodies containing at least 2 classes of binding sites, 1 with high affinity but low capacity, and the other with low affinity but high capacity. An oral glucose tolerance test revealed high serum levels of total insulin associated with relatively low levels of free insulin, but not of C-peptide, suggesting binding of the released insulin to autoantibodies. Regretfully, shortly after the withdrawal of isoniazid, the patient died of respiratory failure unrelated to hypoglycemia, and whether these antibodies were induced by isoniazid remains unknown. We recommend that insulin autoimmune syndrome be one of the differential diagnoses in patients with hyperinsulinemic hypoglycemia.

    A 28-year-old man was hospitalized for a dysenteric syndrome that had developed during the previous days. Physical examination revealed abdominal pains, fever, vomiting and more than ten liquid stools per day. Fresh stool examination showed numerous mobile ciliated trophozoites of Balantidium coli. The patient reported having been on a hike the previous weekend during which he had drunk water through a hydration pouch bladder. Complete resolution was observed after intravenous rehydration and ten days of oral treatment with metronidazole (Flagyl®). Balantidium coli is the largest ciliate protozoan able to infect humans. This parasite is common in pigs and has a worldwide distribution. Human infections, a rare event in industrialised countries, are usually acquired by ingestion of food or water contaminated by mammal faeces. Human B. coli infections are easily treated but may be severe and even fatal if neglected.

    Full Text Available Our aims were to describe the prevalence of pulmonary hypertension in patients with acute respiratory distress syndrome (ARDS, to characterize their hemodynamic cardiopulmonary profiles, and to correlate these parameters with outcome. All consecutive patients over 16 years of age who were in the intensive care unit with a diagnosis of ARDS and an in situ pulmonary artery catheter for hemodynamic monitoring were studied. Pulmonary hypertension was diagnosed when the mean pulmonary artery pressure was >25 mmHg at rest with a pulmonary artery occlusion pressure or left atrial pressure <15 mmHg. During the study period, 30 of 402 critically ill patients (7.46% who were admitted to the ICU fulfilled the criteria for ARDS. Of the 30 patients with ARDS, 14 met the criteria for pulmonary hypertension, a prevalence of 46.6% (95% CI; 28-66%. The most common cause of ARDS was pneumonia (56.3%. The overall mortality was 36.6% and was similar in patients with and without pulmonary hypertension. Differences in patients' hemodynamic profiles were influenced by the presence of pulmonary hypertension. The levels of positive end-expiratory pressure and peak pressure were higher in patients with pulmonary hypertension, and the PaCO2 was higher in those who died. The level of airway pressure seemed to influence the onset of pulmonary hypertension. Survival was determined by the severity of organ failure at admission to the intensive care unit.

    Dumping syndrome is a serious complication that may occur after gastric surgery in approximately 10% of patients in the 1990s. With the increasing number of patients undergoing bariatric surgery, the incidence of dumping syndrome is likely to increase in recent years. It is necessary for clinicians to recognize the syndrome and master its management. We present a case of recurrent loss of consciousness, which was finally accurately diagnosed as late dumping syndrome twelve years after subtotal gastrectomy and successfully treated with acarbose. A 66-year old lean male was found unconscious repeatedly within one year, oral glucose tolerance tests performed before and after acarbose treatment verified the diagnosis of late dumping syndrome. Hypoglycaemia can damage the body in acute and chronic form. Acarbose can be used as a successful treatment modality for reactive hypoglycaemia due to late dumping syndrome by influencing the release of hormone.

    High-energy trauma associated with calcaneal fracture or Lisfranc fracture dislocation and midfoot crushing injuries are known causes of compartment syndrome in the foot. Suppurative infection in the deep osseofascial compartments can also cause compartment syndrome. We describe the case of a 29-year-old female who had developed a suppurative local infection that resulted in acute compartment syndrome after receiving a local hydrocortisone injection for plantar fasciitis. We diagnosed the compartment syndrome, and fasciotomy was promptly undertaken. After more than 2 years of follow-up, she had a satisfactory functional outcome without substantial morbidity. To our knowledge, no other report in the English-language studies has described compartment syndrome due to abscess formation after a local injection of hydrocortisone. The aim of our report was to highlight this rare, but serious, complication of a routine outpatient clinical procedure. Copyright © 2015 American College of Foot and Ankle Surgeons.

    Gluteal compartment syndrome is a relatively rare condition that mostly result from atraumatic causes such as prolonged immobilization due to drug abuse or alcoholic intoxication and incorrect positioning during surgical procedures rather than traumatic causes. Early diagnosis is difficult and sometimes delayed or overlooked because of poor physical signs resulting from altered mental status and inappropriate diagnosis by clinicians. It has been reported that more than half of the cases of gluteal compartment syndrome are associated with crush syndrome and sciatic nerve palsy. Early diagnosis and immediate fasciotomy are necessary to improve the functional prognosis. Here, we report the case of a patient with gluteal compartment syndrome caused by prolonged immobilization after acute alcoholic intoxication. After disease onset, the patient developed complications of crush syndrome and sciatic nerve palsy, but immediate fasciotomy improved his condition.

    1) To characterize normal, horizontal active dynamic visual acuity (DVA) and passive canal plane head thrust DVA (htDVA) across ages to establish appropriate control data and 2) to determine whether horizontal active DVA and passive canal plane htDVA are significantly different in individuals with superior canal dehiscence syndrome (SCDS) before and after surgical repair in the acute (within 10 d) and nonacute stage (>6 wk). Prospective study. Tertiary referral center Patients diagnosed with SCDS (n = 32) and healthy control subjects (n = 51). Surgical canal plugging on a subset of patients. Static visual acuity (SVA), active horizontal DVA, and canal plane htDVA. Visual acuity (SVA, active DVA, and htDVA) declines with age. In SCDS, SVA and active DVA are not significantly affected in individuals after surgical canal plugging; however, htDVA in the plane of the affected canal is significantly worse after canal plugging. Age-based normative data are necessary for DVA testing. In SCDS, htDVA in the plane of the affected canal is normal before surgery but permanently reduced afterward.

  10. Superior Vena Cava Syndrome due to Thrombosis: A Rare Paraneoplastic Presentation of Bronchogenic Carcinoma

    Full Text Available Superior vena cava (SVC syndrome is not an uncommon occurrence in patients with malignancy and it is often described as a medical emergency. In majority of the cases, SVC syndrome occurs due to mechanical obstruction of the SVC by extraluminal compression with primary intrathoracic malignancies. However, intraluminal obstruction due to thrombosis can also produce symptoms and signs of SVC syndrome. Clot-related SVC obstruction is mostly associated with indwelling central venous catheter and pacemaker leads, although such thrombosis can occur spontaneously in a background of a hypercoagulable state, e.g., malignancy. Here, an unusual case of sudden onset SVC syndrome has been reported, which on initial radiologic evaluation was found to have a lung nodule without any significant mediastinal mass or adenopathy compressing SVC. Subsequent investigation with Doppler ultrasonography of the neck showed thrombosis in the right internal jugular, right subclavian and right brachiocephalic vein, which was responsible for SVC syndrome. Histopathological evaluation of lung nodule confirmed presence of an adenocarcinoma. Therefore, venous thromboembolism as a paraneoplastic syndrome should be kept in mind while evaluating a case of SVC obstruction in a cancer patient. Management of the underlying disease is of prime importance in such cases and anticoagulation is the mainstay of therapy. Ability to identify paraneoplastic syndrome may have a significant effect on clinical outcome, ranging from early diagnosis to improved quality of life of the patient.

    Full Text Available Compression of the ulnar nerve in the cubital tunnel is the second most common nerve entrapment syndrome in the upper extremity after carpal tunnel syndrome. Although various etiologies have been described, heterotrophic ossification is rarely seen. Heterotrophic ossification should be kept in mind as a cause of ulnar nerve entrapment after elbow trauma. Early diagnosis and surgical intervention are important in such cases before completion of the maturation phase. We report a case of heterotrophic ossification due to elbow trauma that caused cubital tunnel syndrome. [Hand Microsurg 2014; 3(1.000: 24-28

    Cryptococcus neoformans has a worldwide distribution. Meningoencephalitis is the most common manifestation of cryptococcosis. The outcome of a patient with cryptococcal infection depends on the immune status of the host. Patients with nephrotic syndrome are particularly susceptible to cryptococcal infection not only due to innate changes in their immune system but also because of the immunosuppressive agents used in the treatment. We report an 8-year-old boy with nephrotic syndrome, who developed cryptococcal meningitis and died of fulminant intracranial hypertension.

    Neonatal abstinence syndrome (NAS) due to prenatally exposure to citalopram can develop during the first days of life even with low dose of drug exposure. Supportive management is the first choice but phenobarbital can be used in treatment of this syndrome. Breastfeeding should not be interrupted. These neonates should be followed both for NAS and neurodevelopmental outcome. In this article, we reported a newborn with NAS due to citalopram exposure with a lower dose than previously reported in the literature, during the last six months of pregnancy. Phenobarbital was used because of non-pharmacological treatment failure. Sociedad Argentina de Pediatría.

    A 51-year-old woman had been administered 5 mg/day of prednisolone due to systemic lupus erythematosus (SLE). She developed hypertension, hypokalemia and a pathologic pubic fracture during two years before admission. Although iatrogenic Cushing's syndrome was initially suspected, we diagnosed her as concomitant Cushing's syndrome due to a left adrenal tumor. The elevated endogeneous glucocorticoids were evaluated from urinary excretions of 17-hydroxycorticosteroids, which was 2-fold higher than normal and equivalent to 10 mg of prednisolone. After laparoscopic left adrenalectomy, SLE was favorably controlled with 15 mg of prednisolone, the dosage of which was equivalent to the estimated amount of preoperative glucocorticoids.

    Full Text Available Background. Shock syndrome is an acute tissue hypoperfusion. Early diagnosis and adequate symptomatic and causal treatment are mandatory. In spite of different etiologies (dehidration, bleeding, heart failure, sepsis, clinical signs and symptomes are similar (hypotension, tachicardia, tachipnoe, pallor, cold and wet skin, oliguria and metabolic acidosis. Rarely, the shock syndrome is the consequence of the adrenal insufficiency due to hypopituitarism caused by brain tumor where early treatment with hydrocortisone is urgent.Methods. This article presents a patient with a shock syndrome and multiorgan failure. Endocrinological testing and brain CT demonstrated an endocrinologically inactive tumor of hypophysis. The tumor was growing into adjacent hypophyseal tissue and causing hypopituitarism with secondary hypothyroidism and adrenal insufficiency and deficit of both gonadotropins and growth hormone.Conclusions. Primary or secondary adrenal insufficiency are among rare causes of shock syndrome. Whenever it is suspected, estimation of serum levels of cortisol and ACTH is necessary and immediate treatment with hydrocortisone should be instituted.

    2009-09-01

    Full Text Available Cushing syndrome is rare in infancy and usually due to an adrenocortical tumor (ACT. We report an infant with Cushing syndrome due to adrenocortical carcinoma. The patient presented at six months of age with a three-month history of growth failure, rapid weight gain, acne, and irritability. Physical examination showed obesity, hypertension, and Cushingoid features. Biochemical evaluation showed very high serum cortisol, mildly elevated testosterone, and suppressed ACTH. Abdominal MRI revealed a heterogeneous right adrenal mass extending into the inferior vena cava. Evaluation for metastases was negative. The tumor was removed surgically en bloc. Pathologic examination demonstrated low mitotic rate, but capsular and vascular invasion. She received no adjuvant therapy. Her linear growth has improved and Cushingoid features resolved. Hormonal markers and quarterly PET scans have been negative for recurrence 24 months postoperatively. In conclusion, adrenocortical neoplasms in children are rare, but should be considered in the differential diagnosis of Cushing syndrome.

    2011-08-01

    Full Text Available Abstract Introduction Pancoast syndrome is characterized by Horner syndrome, shoulder pain radiating down the arm, compression of the brachial blood vessels, and, in long-standing cases, atrophy of the arm and hand muscles. It is most commonly associated with lung carcinoma but rarely is seen with certain infections. Case presentation We present the case of a 51-year-old Caucasian man who had acute myeloid leukemia and who developed a rapidly fulminating pneumonia along with signs and symptoms of acute brachial plexopathy and left Horner syndrome. Also, a purpuric plaque developed over his left chest wall and progressed to skin necrosis. The skin biopsy and bronchoalveolar lavage showed a Rhizopus species, leading to a diagnosis of mucormycosis. This is a rare case of pneumonia due to mucormycosis associated with acute Pancoast syndrome. Conclusions According to our review of the literature, only a few infectious agents have been reported to be associated with Pancoast syndrome. We found only three case reports of mucormycosis associated with acute Pancoast syndrome. Clinicians should consider mucormycosis in their differential diagnosis in a patient with pulmonary lesions and chest wall invasion with or without neurological symptoms, especially in the setting of neutropenia or other immunosuppressed conditions. It is important to recognize this condition early in order to target therapy and interventions.

    Adenocorticotropic hormone (ACTH)-dependent Cushing's syndrome in infancy is extremely rare. We describe the case of a sacro-coccygeal ectopic ACTH-secreting immature teratoma in an infant who also presented the triad of defects characteristic of Currarino syndrome. A girl was born with a large immature teratoma in the sacro-coccygeal region associated with anal atresia. At the age of 7 days, the concentration of α-fetoprotein (AFP) was above the age-specific normal range. Two non-radical surgical excisions of the tumour were performed. At the age of 7 months, she developed polyphagia, acne, hirsutism, hypertension and hypokalemia with elevated ACTH and absence of serum cortisol circadian rhythm. Immunostaining of tumour tissue showed ACTH-immunoreactive cells. Due to unsuccessful therapy with ketoconazole and resistance to antihypertensive medications [blood pressure (BP) 210/160 mmHg], metyrapone was administered, which controlled her ACTH and cortisol levels in the normal range. Following further removal of tumour bulk after three operations during the first year of life, there was a decrease of BP to normal values. A rare case of ectopic ACTH syndrome causing Cushing's syndrome in infancy in the context of Currarino syndrome is reported. Radical surgery has resulted in excision of the tumour and current control of Cushing's syndrome.

    Full Text Available Stroke is generally considered to be the first preliminary diagnosis in patients presenting with acute hemiparesia in the emergency department. But rarely in unexpected spontaneous neurological pathologies that may lead to hemiparesis. The data from 8 non-traumatic patients who underwent surgical treatment for brown-sequard syndrome (BSS were reviewed retrospectively. All patients were initially misdiagnosed with strokes. Two of the patients had spinal canal stenosis, two had spinal epidural hematomas, one had an ossified herniated disc and three had soft herniated discs. None of the patients complained of significant pain at the initial presentation. All of the patients had a mild sensory deficit that was initially unrecognized. The pain of the patients began to become evident after hospitalization and, patients transferred to neurosurgery department. Cervical spinal pathologies compressing the corticospinal tract in one-half of the cervical spinal canal may present with only hemiparesis, without neck and radicular pain. If it's too late, permanent neurological damage may become inevitable while it is a correctable pathology.

    Behcet's disease is a multisystemic vasculitis of unknown etiology with a chronic relapsing course. Vasculitis in Behcet's disease with predominant vascular involvement is the only vasculitis that affects both arteries and veins of any size. Involvement of the renal artery and inferior vena cava is rare among the arteries and veins, respectively. When disease affect the veins, it is in the form of thrombosis. Arterial complications include aneurysms, stenosis and occlusions. Both rupture of arterial aneurysm and occlusion of suprahepatic veins, causing Budd-Chiari syndrome, are associated with a high mortality rate. Vascular involvement is more common in male patients than in female patients. Men and patients with a younger age of onset present with a more severe prognosis. In this case report, we describe a very rare cause of intrarenal arterial aneurysm's rupture with previous Budd-Chiari syndrome due to Behcet's disease and successful angiographic embolization of actively bleeding aneurysm.

    Breast cancer most often presents as a palpable mass or with an abnormal mammogram. Much less commonly, breast cancer may present as a paraneoplastic syndrome. Dermatomyositis (DM) is a rare disease most often considered a complement-mediated idiopathic inflammatory myopathy manifested by classic skin findings and proximal muscle weakness. However, DM may also be due to a paraneoplastic syndrome associated with an underlying malignancy. The authors present a case report of a woman with presumed contact dermatitis who was diagnosed with breast cancer in the setting of progressive fatigue and muscle weakness. DM was subsequently diagnosed. Treatment of DM simultaneous with treatment of the breast cancer led to regression of DM. The diagnosis of DM in an adult should raise suspicion of an underlying malignancy. Breast cancer is a common disease that may rarely present with uncommon features that may divert attention from the underlying malignancy.

    Lumbar canal stenosis is an increasingly recognized condition in patients more than 65 years of age. The clinical syndrome is dominated by neurogenic claudication. The natural history of the Condition is not yet well described. Long-term results of surgical therapy are frequently disappointing, and reoperation is required in more than 10% of patients. Nonoperative treatment options include physical therapy exercise programs, calcitonin, analgesics, and epidural steroid injections. A clinical pathway for management of symptomatic stenosis, emphasizing an initial nonoperative approach, is suggested.

    A thoracic outlet syndrome (TOS) is caused by arterial or nervous obstruction because of skeletal or muscular anomalies and hypertrophies. Congenital rib anomalies occur with low incidences (0.15-0.31%), predominantly affect the right side and are normally diagnosed at a young age or remain asymptomatic throughout life. Here, we report on the unusual case of a 71-year-old female patient with subacute ischemia of the left arm due to a TOS resulting from Srb anomaly, a very rare congenital rib anomaly.

    Full Text Available Complex regional pain syndrome (CPRS, is a painful and disabling disorder that can effect one or more extremities, characterized by a combination of vasomotor, sudomoto rand dystrophic alterations and may cause restriction in movements. The pain of this condition out of proportion to the severity of the initial injury. There are many aetiologic factors such as soft tissue injury, surgery, immobilization or myocardial ischemia. The pathophysiology of CPRS is not clear but peripheral and central sensitization resulting in neurogenic inflammation has been held responsible. This case report discribes the clinical condition of CPRS due to cat bite, and is presented to emphasize rare etiologic factors that may cause CPRS.

    Mild hypokalemia is common and encountered in a multitude of diseases, but severe hypokalemia leading to rhabdomyolysis is relatively rare. The watery diarrhea, hypokalemia, achlorhydria (WDHA) syndrome caused by vasoactive intestinal polypeptide (VIP)-producing tumors, is an extremely rare cause of hypokalemic rhabdomyolysis and the literature is limited to one case report. We report a second case of an adult who presented with rhabdomyolysis due to severe hypokalemia. Further evaluation revealed that he had a VIP-producing pancreatic neuroendocrine tumor (NET), which was the cause of his hypokalemic rhabdomyolysis. Although rare in occurrence, a high index of suspicion is of paramount importance for establishing the correct diagnosis and treatment.

  5. Novel SCN5A mutation associated with idiopathic ventricular fibrillation due to subclinical Brugada syndrome

    Full Text Available Idiopathic ventricular fibrillation can be caused by subclinical channelopathies such as Brugada syndrome. Our objective is to study the clinical behaviour of a new SCN5A mutation found in a woman with idiopathic ventricular fibrillation. A 53-year-old woman presented with multiple episodes of ventricular fibrillation, a structurally normal heart and normal baseline electrocardiogram. Genetic testing included KCNQ1, KCNH2, SCN5A, KCNE1, KCNE2 and KCNJ2 and identified a mutation in SCN5A (D1816fs/g98747-98748insT. We studied 15 immediate family members by means of electrocardiogram, echocardiogram, flecainide challenge test and genetic study. Eight subjects had the mutation. The flecainide challenge test was positive for Brugada syndrome in two subjects in the case group and none in the control group. The PR and QRS intervals on the baseline electrocardiogram were longer in the case group. The left atrial volume indexed to body surface was higher in the case group, likely due to the fact that two patients with the mutation had atrial fibrillation and none had it in the control group. The D1816fs/g98747-98748insT mutation in SCN5A may be associated with idiopathic ventricular fibrillation and Brugada syndrome with a broad phenotypic spectrum and incomplete penetrance. Genetic testing may be useful to identify the etiology of idiopathic ventricular fibrillation in patients with a negative thorough clinical evaluation.

    Ellis-Van Creveld Syndrome or chondrectodermal dysplasia is produced by an autosomal recessive inheritance secondary to mutation in the short arm of chromosome 4. The syndrome affects multiple organs. It is described as a clinical tetrad that involves chondrodysplasia, ectodermal dysplasia, polydactyly and congenital heart defects. It is only known from reports and case series. We present a three months old male, without relevant family history, who presented chondrodysplasia, upper lip merged to palate, bilateral sinpolydactyly in the hands, developmental dysplasia of the hip, narrow chest with short ribs, and heart defects. This case is the first report of EVC in Peruvian literature.

    We describe a patient with extrahepatic portal venous obstruction due to a giant hepatic hemangioma associated with Kasabach-Merritt syndrome. A 67-year-old woman presented with upper abdominal distension and appetite loss. The medical history was not relevant to the current disorder. Initial laboratory tests revealed the following: serum platelet count, 9.9 × 10⁴/µL; serum fibrinogen degradation products, 12 µg/mL; prothrombin time, 1.26; and serum fibrinogen, 111 mg/dL. Computed tomography demonstrated homogenous low-density areas, 15 cm in diameter, in the left lobe of the liver. Common hepatic arteriography revealed a hypervascular tumor with pooling of contrast medium in the delayed phase. The portal venous phase of supramesenteric arteriography revealed obstruction and cavernous transformation of the portal vein. We diagnosed extrahepatic portal venous obstruction due to a giant hepatic hemangioma associated with Kasabach-Merritt syndrome. Laparotomy was performed, and the liver was found to be markedly enlarged. After mobilization of the left lobe, left hepatectomy was performed with intermittent clamping. After resection, Doppler ultrasonography revealed recovery of the portal venous flow. The cavernous transformation shrank. Pathologic examination of the surgical specimen confirmed the presence of a giant benign hepatic cavernous hemangioma. The patient was discharged 16 days after operation. Laboratory data and complications improved after 2 months.

    Stroke is generally considered to be the first preliminary diagnosis in patients presenting with acute hemiparesia in the emergency department. But rarely in unexpected spontaneous neurological pathologies that may lead to hemiparesis. The data from 8 non-traumatic patients who underwent surgical treatment for brown-sequard syndrome (BSS) were reviewed retrospectively. All patients were initially misdiagnosed with strokes. Two of the patients had spinal canal stenosis, two had spinal epidural hematomas, one had an ossified herniated disc and three had soft herniated discs. None of the patients complained of significant pain at the initial presentation. All of the patients had a mild sensory deficit that was initially unrecognized. The pain of the patients began to become evident after hospitalization and, patients transferred to neurosurgery department. Cervical spinal pathologies compressing the corticospinal tract in one-half of the cervical spinal canal may present with only hemiparesis, without neck and radicular pain. If it's too late, permanent neurological damage may become inevitable while it is a correctable pathology.

    Mirror syndrome is a rare complication of twin-twin transfusion syndrome (TTTS). Its clinical picture includes massive edema, oliguria, and hemodilution in the context of fetal hydrops. The occurrence of mirror syndrome after fetoscopic laser therapy for TTTS has been well documented, but resolution of mirror syndrome before delivery has not been reported in the literature. A 33-year-old woman was referred to our institution at 23(6)/7 weeks' gestation for TTTS, which had been treated with amnioreduction twice: at 21 and 22 gestational weeks, respectively. Mirror syndrome was diagnosed after fetoscopic laser therapy for TTTS at 24 weeks' gestation due to maternal manifestations of pulmonary edema, skin edema, anemia, low blood protein concentration and proteinuria accompanied by donor hydrops. The maternal respiratory symptoms then gradually abated in laser therapy in twin-twin transfusion due to donor hydrops doesn't necessarily predict a poor perinatal outcome.

    Dubin-Johnson syndrome is a chronic, benign, intermittent jaundice, mostly of conjugated hyperbilirubinemia. The level of bilirubin is not expected to be more than 20 mg/dl in this syndrome. In this article, we report a patient who was evaluated for hyperbilirubinemia and liver function test abnormalities and diagnosed with Dubin-Johnson syndrome coexisting with hereditary spherocytosis. We suggest that other diseases should be investigated if patients with Dubin-Johnson syndrome present with severe hyperbilirubinemia. Dubin-Johnson syndrome accompanied by hemolytic diseases might also have high coproporphyrin levels (as in Rotor's syndrome) than expected in pure Dubin-Johnson syndrome.

    Full Text Available Abstract Background Genetic disorders due to kindred marriages are common medical conditions in Iran; however, the legal aspects of abortion remain controversial. This study was undertaken to determine physicians' opinions regarding the termination of pregnancy for three genetic diseases: thalassemia major, hemophilia, and Down's syndrome. Methods A questionnaire was administered to selected physicians by stratified random sampling to determine the following: age, gender, knowledge about prenatal diagnosis of diseases in high risk pregnancies, agreement with abortion, recommended gestational age for abortion, and, if opposed to abortion, the reason. Results Of 323 physicians, who participated in the study, 91.3(295, 40.6(131, and 78.6%(254 were in agreement and 8.7(28, 59.4(192, and 21.4%(69 were opposed to abortion for thalassemia major, hemophilia, and Down's syndrome, respectively. Among 289 physicians opposed to abortion in respect of each of all three conditions, the following reasons were cited: religion, 18; emotional, 10; quality of care, 23; hope to find a new treatment option in the future, 103; miscellaneous reasons, 6; and a combination of these reasons, 129. Among 680 physicians in agreement with abortion in relation to all of the diseases, 4.6%(31 were agreed with abortion in less than 12 weeks gestation, 79.2%(538 in less than 16 weeks gestation, 5.6%(38 in less than 20 weeks gestation, 2.2%(15 in less than 24 weeks gestation, and 8.4%(58 were agreed with beyond the 24 weeks of gestational age. Conclusion The majority of physicians were in agreement with abortion for thalassemia major and Down's syndrome because of the overall prognosis, but opposed to abortion for hemophilia.

    Beckwith-Wiedemann syndrome (BWS) is an overgrowth syndrome with an increased risk of cancer. Most BWS patients show a molecular defect in the 11p15 region that contains imprinted genes. BWS has been associated with malignant neoplasms during infancy. Descriptions of benign tumors, especially in adult patients, are rarer. We report the case of a BWS patient with pituitary adenoma caused by loss of methylation (LOM) at ICR2 (locus CDKN1C/KCNQ1OT1). The patient was referred to an endocrinology unit for suspicion of Cushing's disease due to a history of macroglossia and hemihyperplasia. Biological tests led to the diagnosis of ACTH-dependent hypercortisolism. MRI showed a microadenoma of the pituitary gland, confirming the diagnosis of Cushing's disease. DNA methylation analysis revealed LOM at ICR2 that was in a mosaic state in the patient's leukocytes, but was present in nearly all cells of the pituitary adenoma. The epigenetic defect was associated with a somatic USP8 mutation in the adenoma. Pituitary adenoma rarely occurs in patients with BWS. However, BWS should be considered in cases of pituitary adenoma with minor and/or major signs of BWS. The association between ICR2 LOM and USP8 mutation in the adenoma is questionable. © 2016 S.

    The Angelman syndrome (AS) is a neurological disorder characterized by severe mental retardation, absent speech, seizures, gait disturbances, and a typical age-dependent facial phenotype. Most cases are due to an interstitial deletion on the maternally inherited chromosome 15, in the critical region q11-q13. Rare cases also result from paternal uniparental disomy of chromosome 15. In a group of 14 patients with sporadic AS diagnosed in Switzerland, we found 2 unrelated females with paternal isodisomy for the entire chromosome 15. Their phenotypes were milder than usually seen in this syndrome: one girl did not show the typical AS facial changes; both patients had late-onset mild seizures; as they grow older, they had largely undisturbed gross motor functions, in particular no severe ataxia. Both girls were born to older fathers (45 and 43 years old, respectively). The apparent association of a relatively milder phenotype in AS with paternal uniparental disomy will have to be confirmed by detailed clinical descriptions of further patients. 25 refs., 2 figs., 1 tab.

    The advent of highly active antiretroviral therapy for HIV infection dramatically changed the landscape of the disease. Ritonavir, a protease inhibitor (PI) frequently used in low doses to 'boost' the concentrations of other PIs, inhibits the cytochrome P450 3A4 isoenzyme, a common metabolic pathway to multiple drugs, so the potential for drug interactions is not negligible. A 39-year-old man with HIV-1 infection, treated with a ritonavir-boosted PI, was started on fluticasone/salmeterol inhaler and intranasal fluticasone, in 2009, in the setting of asthma and allergic rhinitis. In 2013, he presented with 1-year evolution of symptoms suggesting Cushing's syndrome, and was experiencing recurrent falls. A spine CT showed a vertical L3 fracture and thoracolumbar erosions; a bone density scan revealed severe osteoporosis. Hormonal assays were compatible with hypothalamic-pituitary-adrenal axis suppression, and iatrogenic Cushing's syndrome due to ritonavir-fluticasone interaction was considered. Fluticasone was suspended and oral corticosteroid replacement initiated, with a favourable outcome. 2015 BMJ Publishing Group Ltd.

    Differentiation syndrome is a life-threatening complication of therapy that is carried out with agents used for acute promyelocytic leukemia. Its physiopathology comprehends the production of inflammatory mediators by differentiating granulocytes, endothelial and alveolar cells due to stimulation by all-trans retinoic acid and leading to sustained systemic inflammation. Treatment with high cut-off continuous veno-venous hemodialysis (HCO-CVVHD) was performed to reduce the circulating mediators of systemic inflammation. After 52 h of treatment, an important reduction was observed in inflammatory mediators (IL-1β: from 10 to 2 pg/ml; IL-8: from 57 to 40 pg/ml; TNF-α: from 200 to 105 pg/ml; IL-6: from 263 to 91 pg/ml), as well as in anti-inflammatory mediators (IL-10: from 349 to 216 pg/ml). HCO-CVVHD should be explored as a part of treatment in systemic inflammation states other than sepsis (e.g., differentiation syndrome). Furthermore, its immunomodulatory effects could be particularly useful in immunocompromised patient treated with corticosteroids. © 2014 S. Karger AG, Basel.

    Full Text Available Refeeding syndrome (RS is a serious and potentially fatal disorder. It is caused by a shift of fluids, sodium, potassium, magnesium and phosphorus as well changes in the metabolism of glucose, protein, fat and vitamins following the refeeding of malnourished patients, whether enterally or parenterally. RS has rarely been reported in patients with advanced kidney disease probably due to the pre-existing hyperphosphatemia, hypermagnesemia and hyperkalemia in these patients. In the following report, we present a patient with nephronophthisis type 1 deletion syndrome in whom her main previous nutrition was limited to simply rehydration to avoid renal replacement therapy. On presentation, she was cachectic and dehydrated with advanced kidney failure. She was treated with medical nephrectomy using non-steroidal anti-inflammatory drugs and then placed on maintenance hemodialysis. Percutaneous endoscopic gastrostomy was used for her initial feeding. Care was exercised during her early refeeding with regard to correction of fluids and essential electrolytes, viz. potassium, phosphorus and magnesium, as well as multivitamins to avoid the cardiovascular and neurological complications of RS. However, the changes in the gut, pancreas and liver as well as her hyperlipidemia were a clear obstacle. Fortunately, the ileus and pancreatitis she developed on refeeding improved dramatically with a decrease of the feeding dose to half; however, the liver abnormalities and hyperlipidemia were severe and slow to recover. These improved after addition of ursodeoxycholic acid and permitted successful increase of the dose of feeding subsequently.

    2006-01-01

    Resent advances have led to the reexamination of the intraosseous pathway of the chorda tympani a few years ago and they stated that the nerve never enters the mandibular fossa and its exit the skull base in the sphenopetrosal fissure. In our report, 58 temporal bones were investigated after maceration and formalin fixation in order to understand the development of the anterior chordal canal. Our study revealed that the chorda tympani leaves the tympanic cavity through the tympanosquamosal fissure before formation of the anterior chordal canal of Huguier. This canal is situated parallel to and in front of the musculotubal canal and formed by the processus inferior tegminis tympani and the sphenoid bone between the second and fifth years of age. Prior to the age of 2, only the exit of the bony canal exists which is gradually followed by the appearance of a groove in the growing processus inferior tegminis tympani. The borders of the groove elevate and develop to upper and lower plates which lengthen with similar plates of the sphenoid bone, completing the anterior chordal canal by the fifth postnatal year. The entrance of the canal develops above the petrotympanic fissure and similar to the canal itself, it is also completely formed in the fifth year. In case of an incomplete development the anterior chordal canal remains partially opened laterally which might allow the head of the mandibula to effect the chorda tympani mechanically causing Costen's syndrome.

    Full Text Available Cushing’s syndrome (CS may lead to severe maternal and fetal morbidities and even mortalities in pregnancy. However, pregnancy complicates the diagnosis and treatment of CS. This study describes a 26-year-old pregnant woman admitted with hypertension-induced headache. Hormonal analyses performed due to her cushingoid phenotype revealed a diagnosis of adrenocorticotropic hormone- (ACTH- independent CS. MRI showed a 3.5 cm adenoma in her right adrenal gland. After preoperative metyrapone therapy, she underwent a successful unilateral laparoscopic adrenalectomy at 14-week gestation. Although she had a temporary postoperative adrenal insufficiency, hormonal analyses showed that she has been in remission since delivery. Findings in this patient, as well as those in previous patients, indicate that pregnancy is not an absolute contraindication for laparoscopic adrenalectomy. Rather, such surgery should be considered a safe and efficient treatment method for pregnant women with cortisol-secreting adrenal adenomas.

    Inadequate therapeutic response to parenteral corticosteroids in patients with acute bronchial asthma is infrequent. We report four patients whose bronchial asthma symptoms worsened after treatment with parenteral corticosteroids. All had larvae of Strongyloides stercoralis in the stool. The new attack or the exacerbation of asthma appeared to be precipitated by systemic corticosteroid administration. The paradoxic therapeutic response of asthma to glucocorticoides was the major pulmonary manifestation of Strongyloides superinfection; there was no evidence of other organ involvement. Individuals with new onset of bronchial asthma or worsening of asthmatic episodes concurrent with the use of systemic corticosteroids should have thorough investigation for possible superinfection due to Strongyloides stercoralis. This is particularly important for patients who have resided in areas where intestinal helminthic infections are endemic. Discontinuance of steroid therapy or reduction in dosage of parenteral steroids appears necessary. Treatment with thiabendazole appears to be effective in patients with limited hyperinfection syndrome.

    Angelman syndrome (AS) is a neurogenetic disorder causing severe to profound intellectual disability, absent or very limited speech and a high risk for seizures. AS is caused by a loss of function of the maternally-derived UBE3A allele due to one of several mechanisms including imprinting defects (ImpDs). We present a girl with AS due to a mosaic ImpD who has relatively high developmental function (VABS-II composite score of 76) and communication skills (as demonstrated in supplemental video links). Given the patient's relatively mild developmental impairment, without clinical evidence of seizures, gait disturbance or inappropriate laughter, the diagnosis of AS was not initially suspected. Initial laboratory testing for AS was inconclusive but additional studies suggested mosaic ImpD and characteristic EEG findings provided further support for the clinical diagnosis. Our patient, along with other case reports of children with AS and relatively mild phenotypes, raises the question as to whether there exists an undiagnosed group of individuals with mild intellectual disability and expressive speech delays due to mosaic methylation defects of the chromosome 15q11.2-13 region. Population studies may be needed to determine if such an undiagnosed group exists. © 2015 Wiley Periodicals, Inc.

    The effect of anxiety and depression on patients with acute coronary syndromes (ACS) warrants investigation, especially during periods of economic crisis. To investigate the relation between anxiety and depression in patients presenting with ACS due to financial crisis and to investigate whether these two entities could predict long-term cardiovascular mortality. Anxiety and depression symptoms were assessed in 350 patients (210 men) presenting with ACS, with 70 (20%) patients showing elevated scores (Hellenic Heart Failure Protocol). Over a mean follow-up of 48 months there were 36 (10%) cardiovascular deaths. Cox proportional hazards models adjusted for other prognostic factors (including age, sex, marital status, creatinine levels, left ventricular ejection fraction, heart failure, atrial fibrillation, previous hospitalisation, and baseline medications) showed that elevated anxiety and depression scores significantly predicted cardiovascular mortality (primary outcome) and all-cause mortality. Elevated anxiety and depression symptoms are related to cardiovascular mortality due probably to financial crisis, even after adjustment for other prognostic indicators in patients with ACS, who received optimised medical treatment.

    Full Text Available Abstract Background Malnutrition and inflammation are common and serious complications in patients with acute kidney injury (AKI. However, the profile of these complications in patients with AKI caused by crush syndrome (CS remains unclear. This study describes the clinical characteristics of malnutrition and inflammation in patients with AKI and CS due to the Wenchuan earthquake. Methods One thousand and twelve victims and eighteen healthy adults were recruited to the study. They were divided into five groups: Group A was composed of victims without CS and AKI (904 cases; Group B was composed of patients with CS and AKI who haven't received renal replacement therapy (RRT (57 cases; and Group C was composed of patients with CS and AKI receiving RRT (25 cases; Group D was composed of earthquake victims with AKI but without CS (26 cases; and Group E was composed of 18 healthy adult controls. The C-reactive protein (CRP, prealbumin, transferrin, interleukin-6 and TNF-α were measured and compared between Group E and 18 patients from Group C. Results The results indicate that participants in Group C had the highest level of serum creatinine, blood urea nitrogen and uric acid. Approximately 92% of patients with CS who had RRT were suffering from hypoalbuminemia. The interleukin-6 and CRP levels were significantly higher in patients with CS AKI receiving RRT than in the control group. Patients in Group C received the highest dosages of albumin, plasma or red blood cell transfusions. One patient in Group C died during treatment. Conclusions Malnutrition and inflammation was common in patients with earthquake-related CS and had a negative impact on the prognosis of these subjects. The results of this study indicate that the use of RRT, intensive nutritional supplementation and transfusion alleviated the degree of malnutrition and inflammation in hemodialysis patients with crush syndrome.

    Some typical and atypical Rett syndrome patients lack known genetic mutations. Mutations in the P/Q type calcium channel CACNA1A have been implicated in epileptic encephalopathy, familial hemiplegic migraine, episodic ataxia 2, and spinocerebellar ataxia 6, but not Rett syndrome. Patient Description: The authors describe a female patient with developmental regression and a de novo, likely pathogenic mutation in CACNA1A who meets 3 of 4 main criteria (stereotypic hand movements, loss of purposeful hand movements, gait disturbance), and 6 of 11 supportive criteria (impaired sleep, abnormal tone, vasomotor disturbance, scoliosis, growth retardation, and screaming spells) for atypical Rett syndrome. Furthermore, she resembles the early seizure variant of Rett syndrome. Previously, 3 children with similar CACNA1A mutations have been reported, but a Rett syndrome phenotype has not been described. CACNA1A mutations should be considered in children presenting with an atypical Rett syndrome phenotype, specifically, the early seizure variant.

    Good syndrome is a rare condition in which thymoma is associated with hypogammaglobulinemia. It is characterized by an increased susceptibility to infections. We report a woman with Good's syndrome diagnosed after severe congenital toxoplasmosis in her daughter, even though she was immunized against this infection during pregnancy. This presentation is very unusual by its early diagnosis and to our knowledge is the first report of parasitic infection in this syndrome. Copyright © 2016. Published by Elsevier SAS.

    Full Text Available Hyperimmunoglobulin M (HIGM type 3 due to CD40 deficiency is a very rare syndrome. Only 16 cases have been reported thus far. The clinical presentation is very variable. We present the first case of this rare disorder from India. The case is of a two-and-a-half-year-old female, with a history of repeated episodes of skin infections and diarrhea since birth. Laboratory evaluation revealed elevated absolute lymphocyte count and an absolute neutrophil count (ANC of 1026/mm 3 . The lymphocyte subset analysis showed normal absolute counts of Natural Killer (NK cells and elevated absolute counts of T-cells (CD4 and CD8 and B-cells. The serum immunoglobulin estimation showed low levels of IgG, IgA, IgE and an elevated level of IgM. The CD154 analysis was normal and expression of CD40 was absent on the B-cells. Molecular analysis showed a novel mutation, with deletion of 3bp (AAG [p.Glu107GlyfsX84] in the homozygous state, in the CD40 gene. Thus the patient was diagnosed as HIGM type 3. The parents were screened and counseled regarding prenatal diagnosis at the time of next pregnancy.

    Thyroid gland disorders are variably associated with Prader-Willi syndrome (PWS). Many of the clinical features in newborns with PWS are similar to those found in congenital hypothyroidism (CH). We report a case of a girl with CH and PWS. At the age of 9 months CH caused by an ectopic sublingual thyroid was diagnosed, and hormone replacement therapy was started. In spite of this treatment a decrease in growth velocity, weight excess and delayed development were observed. At the age of 9 years PWS was suspected on the basis of phenotype and genetic tests confirmed a maternal uniparental disomy of chromosome 15. This is the second reported case of hypothyroidism due to an ectopic sublingual thyroid gland in PWS suggesting that, although rare, an association between CH and PWS may exist. In our case diagnosis of PWS was delayed because mental retardation, hypotonia, obesity and short stature were initially attributed to hypothyroidism. In this context PWS should be considered in obese children with CH who do not improve adequately with l-thyroxine therapy. Also, thyroid function in all PWS children should be assessed regularly in order to avoid delayed diagnosis of hypothyroidism.

    Professional burnout is defined as a state of depletion and loss of motivation accompanied by different mental and physical symptoms. To assess personal losses suffered by correctional officers due to burnout. This cross-sectional study conducted between June and December 2012 included 201 correctional officers in two Bulgarian prisons. The mean age of the whole group was 41.2 (SD 8.0) years. The respondents was mostly male (56.7%), married (72.6%), had a secondary educational level (61.7%), and 76.1% of them had been in current prison work over 5 years. The demographic characteristics had no influence on the occurrence of burnout but there was a correlation between level of burnout and the number of sick-leaves, the need for medical help, and the expenses spent on medications. Officers affected by burnout took more sick-leaves and this affected adversely their remuneration as they lost 3.1% of their annual wages. Their expenses spent on user fees for medical services were 3 times higher. Their monthly expenses spent on medications were 3.14 times higher than those of people without the burnout syndrome. The high level of burnout has a negative personal economic effect on the prison employees.

    Full Text Available A 1-year-old girl born to consanguineous parents presented with unexplained liver failure, leading to transplantation at 19 months. Subsequent partial splenectomy for persistent cytopenia showed the presence of foamy cells, and Gaucher disease was confirmed by homozygosity for the p.Leu483Pro mutation in the GBA gene. She was treated by enzyme replacement therapy (ERT. Clinical follow-up showed mild developmental delay, strabismus, nystagmus and oculomotor apraxia. Biochemical studies revealed multiple respiratory chain deficiencies and a mosaic pattern of deficient complex IV immunostaining in liver and fibroblast. Molecular analysis identified a mtDNA depletion syndrome due to the homozygous p.Pro98Leu mutation in MPV17. A younger sister unaffected by mtDNA depletion, presented with pancytopenia and hepatosplenomegaly. ERT for Gaucher disease resulted in visceral normalization without any neurological symptom. A third sister, affected by both conditions, had marked developmental delay, strabismus and ophthalmoplegia but no liver cirrhosis. In conclusion, intrafamilal variability occurs in MPV17-related disease. The combined pathological effect of Gaucher and mitochondrial diseases can negatively impact neurological and liver functions and influence the outcome in consanguineous families. The immunocytochemical staining of OXPHOS protein in tissues and cultured cells is a powerful tool revealing mosaic pattern of deficiency pointing to mtDNA-related mitochondrial disorders.

    Full Text Available Syncope is a sudden and brief loss of consciousness with postural tone. Its recovery is usually spontaneous. There are various causes of syncope including cardiac, vascular, neurologic, metabolic and miscellaneous origins. The tracing is usually time-consuming and costly. The diagnosis of carotid sinus syncope may sometimes be difficult since the symptoms are nonspecific, especially in older persons. Here, we report the case of a 72-year-old woman who sought medical attention at our hospital due to repeated syncope episodes over the previous 5 years. Neurologic examinations showed negative results (including brain computed tomography. Twenty-four-hour ambulatory electrocardiogram monitoring showed atrial and ventricular premature contractions only. Electrophysiologic study disclosed prolonged corrected sinus node recovery time (1,737 ms with poor atrioventricular conduction. Drop of blood pressure together with sinus bradycardia developed after left side carotid sinus massage. Both carotid sinus hypersensitivity with sick sinus syndrome contributed to this patient's syncope, and after pacemaker placement together with selective serotonin reuptake inhibitor treatment, she was free from syncope thereafter.

He has advanced stage of small cell lung cancer. He had treated with cisplatin and etoposide regimen 10 days ago as a first cure. We diagnosed inapropriate secretion of antidiuretic hormone syndrome (SIADH with low sodium level (118 meq/dl. Although the treatment with water restriction and 3% NaCl infusion, sodium level was not in normal. So we ordered 30 mg tolvaptan tablet. And then sodium levels were reached normal. After one month of discharge from hospital, he has hospitilized with same symptom and diagnosis. And again we ordered same treatment procedure and tolvaptane treatment. He had normal sodium (136 mEq/dl level during his follow up. This case demostrate that tolvaptane treatment is suitable aproaches in hyponatremia due to SIADH in oncologic patient.

    2016-05-01

    Iatrogenic Cushing's syndrome (ICS) is caused by exogenous corticosteroid administration with suppression of the hypothalamic-pituitary-adrenal axis. It has been commonly described with oral and topical steroid use, but scarce reports have documented intranasal steroid usage as the etiology in infancy. In this article, we describe a case of a 4-month-old infant who developed ICS after 6 weeks of intranasal dexamethasone ophthalmic solution administration for nasal obstruction. To our knowledge, this is the youngest patient reported with ICS due to intranasal use of a prescribed dose of an ophthalmic steroid. His hypothalamic-pituitary-adrenal axis recovered fully 4.5 months after steroid discontinuation. Because of the small body surface area and supine position during administration, infants are particularly susceptible to ICS. Given that intranasal steroids are commonly prescribed to infants and children for a variety of diagnoses, this case highlights the risks inherent in the use of intranasal steroid drops, particularly in young infants, for both adrenal suppression and linear growth deceleration, even with short-term use. Close monitoring of these patients' height and weight should occur while on steroid treatment, with every effort made to decrease or discontinue steroid use when possible.

    Blue rubber bleb nevus syndrome (BRBNS) is a rare disease characterized by vascular malformations mostly involving skin and gastrointestinal tract. This disease is often associated with sideropenic anemia and occult bleeding. We report the case of chronic severe anemia in an old patient under oral anticoagulation treatment for chronic atrial fibrillation. At admission, the patient also presented fever and increased laboratory parameters of systemic inflammation (ferritin 308 mcg/L, C-reactive protein (CRP) 244 mg/L). A small bluish-colored lesion over the left ear lobe was observed. Fecal occult blood test was negative as well as other signs of active bleeding. Lower gastrointestinal endoscopy revealed internal hemorrhoids and multiple teleangiectasias that were treated with argon plasma coagulation. Videocapsule endoscopy demonstrated multiple bluish nodular lesions in the small intestine. Unexpectedly, chronic severe anemia due to systemic inflammation was diagnosed in an old anticoagulated patient with BRNBS. The patient was treated with blood transfusions, hydration, antibiotic treatment, and long-acting octreotide acetate, without stopping warfarin. Fever and inflammation disappeared without any acute gastrointestinal bleeding and improvement of hemoglobin levels at three-month follow up. This is the oldest patient presenting with chronic anemia, in which BRNBS was also diagnosed. Surprisingly, anemia was mainly caused by systemic inflammation instead of chronic gastrointestinal bleeding. However, we would recommend investigating this disease also in old subjects with mild signs and symptoms.

    To evaluate the effectiveness of the ICare rebound tonometer in patients with overestimated intraocular pressure (IOP) due to tight orbit syndrome and to identify factors affecting the development of tight orbit syndrome in glaucoma patients. We investigated 84 eyes in 84 glaucoma patients, of which 14 eyes were classified in the tight orbit syndrome group and 70 eyes in the control group. IOP was measured using the ICare tonometer and the Goldmann applanation tonometer (GAT). The demographic data, medical histories, ocular histories, and detailed ocular drug histories of the two groups were compared to identify factors contributing to the development of tight orbit syndrome. In the tight orbit syndrome group, the ICare tonometer significantly underestimated the IOP by approximately 8.6 mmHg compared with the GAT. In the control group, the IOP readings of the GAT and the ICare tonometer did not differ significantly. Bland-Altman analysis showed that the mean difference between measurements taken using the GAT and those taken using the ICare tonometer was 2.5 ± 6.3 mmHg. The difference between the GAT and ICare tonometer measurements was greater in the tight orbit syndrome group (8.6 ± 5.3 mmHg) than in the control group (1.3 ± 2.7 mmHg). Multivariate regression analysis revealed that only the use of prostaglandin analogs (PGAs) was associated with the development of tight orbit syndrome. The ICare tonometer is a suitable alternative device for use in patients with tight orbit syndrome in whom the IOP may be overestimated with the GAT. The prolonged use of PGAs is significantly associated with the development of tight orbit syndrome.

    Full Text Available We have previously reported that subarachnoid hemorrhage due to ruptured intracranial aneurysm (SH is associated with changes in the hormonal profile in the first 24 hours after the event. We proposed that the hormonal changes observed are due to the intense stress to which the patients are exposed. However, the thyroidal hormonal profile is indicative of the presence of a nonthyroidal illness syndrome (NTIS. In this paper, we examined whether the change in the thyroid hormone profile is compatible with a NTIS. Two groups of patients were included in the study: A 30 patients with SH (21 females and 9 males; 41.7±11.4 years and B a control group including 25 patients with benign diseases of the spine (BDS (lumbar disc hernia or stable spinal trauma (8 females and 17 males; 41.3±14.2 years. In a subgroup of eight patients of each group serum triiodothyronine (T3 and reverse T3 levels were measured. The blood samples were obtained between 8:00 and 9:00 AM. The following results were obtained: The SH group had smaller serum T3 and free T4 levels than the BDS group (p<0.05: T3 (ng/mL: SH = 58.7±1.1 and BDS = 74.5±13.9; free T4 (ng/dL: SH = 0.9±0.2 and BDS = 1.1±0.3. There was no significant difference in the serum levels of total thyroxine (T4 and thyroid-stimulating hormone (TSH between the two groups: T4 (µg/dL: SH = 6.9±1.1 and BDS = 7.4±2.1; TSH (µUI/mL: SH = 1.5±0.8 and BDS = 1.8±1,0. In the sample of eight patients of each group we had the following results: T3 (ng/mL: SH = 66.8±3.8 and BDS = 77.2±1.1 (p <0.05; reverse T3 (ng/dL: SH = 32.8±8 and BDS = 24.7±2.2 (NS; T3/ reverse T3 ratio: SH = 2.6±0.3 and BDS = 3.3±0.4 (NS. Thyreoglobulin and microsomal antibodies were not detectable, except in one patient in the SH group. In conclusion, the SH patients present serum levels of T3 and free T4 significantly lower than that of BDS patients; the thyroidal hormone profile suggests that SH patients have developed the nonthyroidal

    Full Text Available Renal tubular disorders are an important cause of refractory rickets. Wilson′s disease, an inherited disorder of copper metabolism has varied presentations. We present a case of refractory rickets due to Fanconi′s syndrome attributable to Wilson′s disease. An adolescent girl presented with pain in the hip and knee joints and a knock-knee deformity since six years. She had received multiple doses of cholecalciferol with little improvement. There was no history of seizures, polyuria, jaundice, intake of drugs, or similar complaints in the family. Examination revealed a severely short stature with widening of the wrist joint and genu valgum. Examination of the central nervous system (CNS was normal. Skeletal radiographs showed features suggestive of rickets at the hip and knee joints. Routine biochemistry was normal, 25-hydroxyvitamin D [25(OHD] was adequate (57.1 ng/dL, with normal corrected calcium (9.24 mg/dL, low phosphate (2.76 mg/dL, elevated bone-specific alkaline phosphatase, and normal renal functions. Twenty-four-hour urine revealed phosphaturia, kaliuresis, and glucosuria with normal blood sugars and aminoaciduria. Blood gas analysis revealed normal anion gap metabolic acidosis with a urine pH of 7. Ammonium chloride (NH 4 CL challenge test revealed proximal tubular acidosis. A search for causes revealed Kayser-Fleischer rings. The diagnosis of Wilson′s disease was confirmed by low serum ceruloplasmin levels (6.5 mg/dL; normal: 18-35 mg/dL with high 24-hour urine copper levels (433 mcg; normal: 20-50 mcg. She was started on a replacement of alkali, phosphate, calcium, and vitamin D, with zinc acetate for Wilson′s disease. Rickets as a presenting feature of Wilson′s disease has been reported rarely. Recognition of this entity is important, as treatment of the primary condition may improve tubular function as well.

    Full Text Available In establishing a genetic diagnosis in heterogeneous neurological disease, clinical characterization and whole exome sequencing (WES go hand-in-hand. Clinical data are essential, not only to guide WES variant selection and define the clinical severity of a genetic defect, but also to identify other patients with defects in the same gene. In an infant patient with sensorineural hearing loss, psychomotor retardation and epilepsy, WES resulted in identification of a novel homozygous CLPP frameshift mutation (c.21delA. Based on the gene defect and clinical symptoms, the diagnosis Perrault syndrome type 3 (PRLTS3 was established. The patient’s brain-MRI revealed specific abnormalities of the subcortical and deep cerebral white matter and the middle blade of the corpus callosum, which was used to identify similar patients in the Amsterdam brain-MRI database, containing over 3000 unclassified leukoencephalopathy cases. In three unrelated patients with similar MRI abnormalities the CLPP gene was sequenced, and in two of them novel missense mutations were identified together with a large deletion that covered part of the CLPP gene on the other allele. The severe neurological and MRI-abnormalities in these young patients were due to the drastic impact of the CLPP mutations, correlating with the variation in clinical manifestations among previously reported patients. Our data shows that similarity in brain-MRI patterns can be used to identify novel PRLTS3 patients, especially during early disease stages, when only part of the disease manifestations are present. This seems especially applicable to the severely affected cases in which CLPP function is drastically affected and MRI abnormalities are pronounced.

    Full Text Available Background: Alcohol withdrawal syndrome (AWS is one of the most serious complications associated with chronic alcoholism. Sudden deaths are not uncommon in AWS. In severe stages of AWS, delirium tremens (DT occurs, which is characterized with agitation, global confusion, disorientation, visual and auditory hallucinations in addition to autonomic hyperactivity. Case report: A 30-year old man, chronic and heavy alcohol drinker for 10 years, abstained from alcohol for 3 days. Consequently, he started having palpitations, sweating and tremors. A day later, he was found having hallucinations and delirium. The patient was immediately transferred to the hospital. On admission, he was stuporous and had difficulty in breathing. He developed generalized seizures later on. He was successfully intubated, but there was bleeding through it. The patient’s condition deteriorated very rapidly and he died within two hours. After death, his body was transferred to forensic department. In autopsy, gastrointestinal tract was found to be intact. Massive pulmonary hemorrhage was present on cut section. Liver was found to be with yellowish discoloration and early cirrhotic changes. In heart, left ventricular hypertrophy with narrowed lumen was present and coronary arteries were patent. Discussion: Alcoholism is associated with liver dysfunction and especially in final phases with cirrhosis. Hence and due to resultant coagulopathy, patients are vulnerable to internal bleedings. Hypertrophic cardiomyopathy also occurs in chronic alcoholics. Therefore, we can speculate that our patient developed pulmonary hemorrhage as a result of combined effect of coagulopathy secondary to cirrhosis, alveolar damage (seizure and artificial ventilation and congestive heart failure. Conclusion: For a patient with delirium, convulsions, respiratory distress and coagulopathy, diagnosis of DT should be kept in mind.

    2008-03-01

    The aim of the present study was to provide a general scheme for pulpectomy of primary molars that may be useful for decision-making about negotiation of root canals and selection of appropriate instruments. A total of 160 vital primary molars in 85 patients (40 males, 45 females) aged 4-6 years were selected. After taking primary radiographs, local anesthesia was induced, and the teeth were isolated using a rubber dam. Canal accessibility index (CAI) and tooth accessibility index (TAI) were calculated according to initial file size. Mandibular first molars had either three canals (79.2%) or four canals (20.8%), and all second molars had four canals. Maxillary first molars had three canals and second molars had either three canals (70.9%) or four canals (29.1%). Lower accessibility of the mandibular first molar distobuccal root accounted for the lower accessibility of these teeth in comparison with mandibular second molars. While three-canal maxillary second molars were more accessible due to the lower accessibility of the distobuccal canal of the maxillary first molar, poor accessibility of the distal canal in four-canal second molars was responsible for the difficult accessibility of these teeth. In conclusion, it seems that the accessibility of a single canal in each tooth determines the difficulty of accessibility for any given tooth. Moreover, while primary second molars are more accessible than first molars, all of them are negotiable.

    Case report and review of the literature. To report a 23-year-old woman with osteochondroma of the lower cervical spine who presented with Horner syndrome and to review the relevant literature. Osteochondroma is the most common benign lesion of bone but rarely affects the spine. Clinical history, routine radiographs, and computed tomography study of the patient were described. A review of the relevant literature was also done. The patient demonstrated a complete disappearance of clinical symptoms on the follow-up examination 60 days after surgery. No patients with Horner syndrome due to a solitary cervical osteochondroma have been previously reported in English-language medical literature. Vertebral involvement of osteochondroma is rare, especially with neurologic compromise. A young patient is presented with a symptomatic solitary osteochondroma of the seventh cervical vertebra who had Horner syndrome. This case report supports surgical intervention of symptomatic osteochondroma of the cervical spine.

  16. Posterior reversible encephalopathy syndrome (PRES, an acute neurological syndrome due to reversible multifactorial brain edema: a case report

    Directory of Open Access Journals (Sweden)

    Camilla Cicognani

    2013-04-01

    Full Text Available Background: The essential features of Posterior Reversible Encephalopathy Syndrome (PRES are headache, mental changes, seizures, visual symptoms and often arterial hypertension. Brain RMN typically shows cortico-sottocortical parieto-occipital edema, with a bilateral and symmetric distribution. PRES develops in clinical conditions as hypertensive encephalopathy, preeclampsia/ eclampsia, autoimmune diseases, after transplantation, infections and as an adverse effect of immunosuppressive drugs or chemotherapy. It usually completely reverses with treatment, although permanent sequelae are possible in case of delayed or missed diagnosis. Case report: We describe the case of a transsexual (M!F and tetraplegic patient, admitted for neck and low back pain. She suddenly developed headache, confusion, seizures and severe hypertension with normal blood tests. RMN showed multiple cortico-sottocortical areas of vasogenic and citotoxic edema in temporo-occipital, parietal, frontal, and cerebellar regions. Soon after the beginning of the antihypertensive therapy, clinical recovery was observed, as well as the disappearance of edema at RMN. Discussion and conclusions: Although PRES is usually associated with definite pathological conditions, it is not always the case, as was for the patient here described, who had no predisposing factors in her past clinical history, and presented hypertension only in the acute phase of the syndrome. Since, moreover, PRES usually presents with acute non specific features and it can be misdiagnosed with other serious diseases, the clinician will be helped by the knowledge of this syndrome to promptly start diagnostic workup and treatments, and avoid permanent neurological deficits.

Case report. Department of gynecology and obstetrics, University Hospital in Ostrava; Departmet of hematooncology, University Hospital in Ostrava; Department of gynecology and obstetrics, Vsetín hospital; Department of hematology and transfusion, Vsetín Hospital. Case of 35-year-old III gravida/II para with previously normal ongoing twin bichorionic biamniotic pregnancy in week 35+0, which was admitted to secondary care delivery room for three days lasting "flu like" symptoms and the right upper quadrant pain. She was icteric, exhausted, but normotensive (120/75 mm Hg). Acute caesarean section was performed for suspected fetal hypoxia and HELLP syndrome. The laboratory exams confirmed coagulopathy and HELLP syndrome second class during the operation. Blood loss was 800 ml. Despite standard treatment of HELLP syndrome, the condition had developed to renal insufficiency, bilateral fluidothorax, alveolar pulmonary edema, encephalopathy and hypertension. In laboratory results dominates markers of coagulopathy, thrombocytopenia and microangiopathic hemolytic anemia with presence of schistocytes. Due to multiple organ dysfunction syndrome with hemolysis of unclear origin, patient was transferred to referral hospital on sixth postoperative day. Therapeutic plasma exchange (TPEX) was promptly begun. Improvement of laboratory parameters occurred already after the first TPEX and after two days there was a significant improvement of neurological status. Nine TPEX procedures were performed. The treatment was terminated after platelet count reached 100×109/l. She was discharged from hospital 21 days after delivery.

    Insulin resistance syndromes without lipodystrophy are an infrequent and heterogeneous group of disorders with variable clinical phenotypes, associated with hyperglycemia and hyperinsulinemia. The three conditions related to mutations in the insulin receptor gene are leprechaunism or Donohue syndrome, Rabson-Mendenhall syndrome, and Type A syndrome. A case is presented on a patient diagnosed with type A insulin resistance, defined by the triad of extreme insulin resistance, acanthosis nigricans, and hyperandrogenism, carrying a heterozygous mutation in exon 19 of the insulin receptor gene coding for its tyrosine kinase domain that is crucial for the catalytic activity of the receptor. The molecular basis of the syndrome is reviewed, focusing on the structure-function relationships of the insulin receptor, knowing that the criteria for survival are linked to residual insulin receptor function. It is also pointed out that, although type A insulin resistance appears to represent a somewhat less severe condition, these patients have a high morbidity and their treatment is still unsatisfactory.

    Heading Abstract.The aim of this study was to assess imaging findings of posterior semicircular dehiscence on computed tomography and to evaluate incidence of posterior and superior semicircular canal dehiscence in patients presenting with vertigo, sensorineuronal hearing loss or in a control group without symptoms related to the inner ear. Computed tomography was performed in 507 patients presenting either with vertigo (n=128; 23 of these patients suffered also from sensorineuronal hearing loss), other symptoms related to the inner ear, such as hearing loss or tinnitus (n=183) or symptoms unrelated to the labyrinth (n=196). All images were reviewed for presence of dehiscence of the bone, overlying the semicircular canals. Twenty-nine patients had superior semicircular canal dehiscence. Of these patients, 83% presented with vertigo, 10% with hearing loss or tinnitus and the remaining 7% with symptoms unrelated to the inner ear. In 23 patients dehiscence of the posterior semicircular canal was encountered. Of these patients, 86% presented with vertigo, 9% with hearing loss or tinnitus and 5% with symptoms unrelated to the inner ear. Defects of the bony overly are found at the posterior semicircular canal, in addition to the recently introduced superior canal dehiscence syndrome. Significant prevalence of vertigo in these patients suggests that posterior semicircular canal dehiscence can cause vertigo, similar to superior semicircular canal dehiscence. (orig.)

    Full Text Available Neuropsychiatric symptoms in Alzheimer’s disease (AD are prevalent, however their relationship with patterns of cortical atrophy is not fully known. Objectives To compare cortical atrophy’s patterns between AD patients and healthy controls; to verify correlations between neuropsychiatric syndromes and cortical atrophy. Method 33 AD patients were examined by Neuropsychiatric Inventory (NPI. Patients and 29 controls underwent a 3T MRI scanning. We considered four NPI syndromes: affective, apathy, hyperactivity and psychosis. Correlations between structural imaging and neuropsychiatric scores were performed by Freesurfer. Results were significant with a p-value < 0.05, corrected for multiple comparisons. Results Patients exhibited atrophy in entorhinal cortices, left inferior and middle temporal gyri, and precuneus bilaterally. There was correlation between affective syndrome and cortical thickness in right frontal structures, insula and temporal pole. Conclusion Cortical thickness measures revealed atrophy in mild AD. Depression and anxiety symptoms were associated with atrophy of right frontal, temporal and insular cortices.

    To describe a case of Posterior Reversible Encephalopathy Syndrome diagnosed in pregnant women with late-eclampsia, as well as its clinical management. A 34 years old patient in her third pregnancy had started with high blood pressure levels during labor; after eleven days postpartum, she presented a decreased right visual acuity; subsequently one episode of seizure followed by partial loss of vision in the right eye. After conducting tests and ruled out stroke, the patient was diagnosed as Posterior Reversible Encephalopathy Syndrome (PRES). Established the clinical management of seizures and hypertensive crisis, there was complete remission of symptoms and reversal of the initial clinical picture. Once properly diagnosed and treated, the Posterior Reversible Encephalopathy Syndrome can present satisfactory progress, especially when associated with an acutely triggered factor, as eclampsia.

    Blau syndrome is characterized by noncaseating granulomatous arthritis, dermatitis, and uveitis, and results from gain-of-function NOD2 mutations. This study was undertaken to identify the genetic cause of the disease in a family with 3 members with Blau syndrome. We studied a family with 3 affected members across 2 consecutive generations. The children's symptoms started early (at 6 and 7 months of age) and included polyarthritis, dermatitis, uveitis, and fever. In contrast, the father's symptoms started later (at 22 years of age) and included noncaseating granulomatous dermatitis and uveitis. We analyzed the NOD2 gene in all patients by both the Sanger method of DNA sequencing and amplicon-based deep sequencing using an Ion Torrent PGM platform. Sanger chromatograms revealed the heterozygous c.1001G>A transition in both children, which resulted in the p.Arg334Gln mutation that causes Blau syndrome. In contrast, the father's chromatograms revealed a small peak of adenine at the c.1001 position, suggesting the presence of a somatic NOD2 mutation. To evaluate this hypothesis, we performed amplicon-based deep sequencing using DNA from different tissues, which confirmed a variable degree (0.9-12.9%) of somatic NOD2 mosaicism. The previous detection of the NOD2 mutation in his daughters strongly suggests the presence of gonosomal (somatic plus gonadal) NOD2 mosaicism in the father. Comparative analyses with Blau syndrome patients carrying the germline p.Arg334Gln NOD2 mutation revealed late onset of the disease, a mild inflammatory phenotype, and an absence of complications in patients with NOD2 mosaicism. This is the first description of gonosomal NOD2 mosaicism as the cause of intrafamilial recurrence of Blau syndrome. Our findings also indicate that Blau syndrome includes more diverse and milder phenotypes than previously described. © 2016, American College of Rheumatology.

    2016-01-01

    Full Text Available Fraley's syndrome results from a rare anatomic variant of the renal vasculature leading to compression of the upper pole infundibulum, caliectasis, hematuria, and flank pain. To date there have been few reported cases in which this condition was treated using a minimally invasive approach. Here, we report a case in which a patient with Fraley's syndrome was successfully treated by performing a laparoscopic YV-infundibulo-pyeloplasty with vasculopexy of a posterior segmental renal artery. Minimally invasive collecting system reconstruction without vascular clamping is feasible, potentially less destructive and offers significant advantages in terms of intraoperative visualization and perioperative patient morbidity.

    We report a case of erectile dysfunction caused by external iliac artery occlusion, associated with pelvic steal syndrome; bilateral internal iliac arteries were patent. The patient stated that he had experienced erectile dysfunction at similar times along with claudication, but he did not mention it before angiography. He expressed that the erectile dysfunction did not last long and that he felt completely okay after the interventional procedure, in addition to his claudication. Successful treatment of the occlusion, by percutaneous transluminal angioplasty and stent implantation, helped resolve erectile dysfunction completely and treat the steal syndrome.

    2006-04-01

    Recently, interhemispheric disconnection syndromes have been noted in patients with agenesis of the corpus callosum (ACC) during the performance of certain tasks. However, few studies have demonstrated an asymmetric disconnection syndrome. In this report, we present just such a syndrome in a patient with ACC, who manifested ambidexterity (but with a left-hand tendency) and had high intelligence, no neurological deficits, and no associated malformations. In a comparison with similar subjects (amateur musician), we studied her asymmetric deficits using four tasks: (1) simple reaction time for visual stimuli, (2) paced finger tapping in synchrony with visual or auditory stimuli, (3) paced finger tapping without an external reference, and (4) rhythmical finger tapping in synchrony with visual or auditory stimuli. While the comparable subjects displayed no significant difference between hands, and the patient showed no significant difference between hands in the auditory paradigm, her tapping performance deteriorated significantly when asked to synchronize the left hand with timed visual stimuli, irrespective of whether finger tapping was paced or rhythmical. We believe that this phenomenon constitutes a novel asymmetrical disconnection syndrome in an ACC subject; these results suggest that synchronization of multimodal temporal information was lateralized in the left hemisphere (in this case), which is something that the ACC patient could not compensate for.

    We report a 6-year-old girl, with no history of previous anaphylactic reaction, who sustained a wasp sting to the volar aspect of her left hand. The child did not present any symptoms at the beginning. She was first examined at the emergency department with developed compartment syndrome, after more than 24 hours later and she was urgently taken to the operating theatre. The midpalmar, thenar, and hypothenar spaces were decompressed, and the transverse carpal ligament was released. At the 11-month followup, she presented with normal function of the hand and normal 2-point discrimination in all fingers. Although the accurate mechanism of the development of compartment syndrome after a wasp sting in children is not thoroughly clear, the treatment seems to be the same as in all other cases of compartment syndrome; urgent fasciotomy. It is very important to keep in mind the possibility, even if it is extremely low, of compartment syndrome after a wasp sting in children; even of those with no history of anaphylactic reaction.

    Full Text Available Bardet–Biedl syndrome (BBS is a rare, autosomal-recessive, debilitating genetic disorder, which can present with multitudinous systemic clinical features including rod-cone dystrophy, polydactyly, Frohlich-like central obesity, mental retardation, hypogonadism, and renal anomalies. Diverse neuromuscular manifestations in patients afflicted by this heterogeneous disorder include ataxia, cervical, and thoracic canal stenoses, presenting as spastic quadriparesis and other gait disturbances. We report a young patient with BBS, who had presented with acute flaccid paraparesis due to severe primary lumbar canal stenosis. She underwent immediate lumbar decompression and discectomy following which she recovered significantly. Acute cauda equina syndrome due to primary lumbar canal stenosis has not been reported as a clinical feature of BBS previously.

    Floating-Harbor syndrome (FHS) is a rare disorder characterized by short stature, delayed bone age, speech delay, and dysmorphic facial features. We report here the molecular analysis of nine cases, fulfilling the diagnostic criteria for FHS. Using exome sequencing, we identified SRCAP as the disease gene in two cases and subsequently found SRCAP truncating mutations in 6/9 cases. All mutations occurred de novo and were located in exon 34, in accordance with the recent report of Hood et al. However, the absence of SRCAP mutations in 3/9 cases supported genetic heterogeneity of FH syndrome. Importantly, no major clinical differences were observed supporting clinical homogeneity in this series of FHS patients. © 2012 Wiley Periodicals, Inc.

    The conditions Juvenile Polyposis Syndrome (JPS) and Hereditary Mixed Polyposis Syndrome (HMPS) are associated with an increased risk of colorectal carcinoma. The genetic mechanisms which explain these conditions have until recently been poorly understood. Recent interest has focused on the transforming growth factor (TGF)-beta signalling pathway and, in particular, on mutations in the SMAD4 gene. However, not all cases of JPS and HMPS have mutations in SMAD4 and focus has now shifted to other components of the TGF-beta pathway to clarify the genetic mechanisms involved in these conditions. In this report, we describe the significance of a bone morphogenetic protein receptor type 1A gene mutation in an Irish family.

    Patient: Male, 22 Final Diagnosis: Lemierre’s syndrome Symptoms: Dyspnea • chest pain • swelling Medication: — Clinical Procedure: Thoracentesis Specialty: Infectious Diseases Objective: Rare co-existance of disease or pathology Background: Lemierre’s syndrome (LS) is a rare syndrome caused by an acute oropharyngeal infection with metastatic spreading. It was described in 1939 as jugular vein septic thrombophlebitis associated with retropharyngeal infection. Different organisms can cause LS, such as Fusobacterium species, Peptostreptococcus, group B and C, Streptococcus, Staphylococcus, and Enterococcus species, but the most commonly isolated pathogen is Fusobacterium necrophorum, a common oral flora. Management depends on the initial presentation, type of pathogen isolated, and proper selection of antibiotics. Case Report: We report a case of a 22-year-old man with no past medical history, who presented with left jaw pain and progressive left facial area swelling associated with dyspnea. A final diagnosis of LS was made based on criteria of computed tomography (CT) of the neck and the clinical symptoms. The patient was started on broad-spectrum antibiotics. Subsequent imaging of the chest showed pleural effusion with septic emboli. He underwent thoracentesis and chest tube placement. Final blood cultures were remarkable for gram-negative rods – Prevotella anaerobes – which supported the diagnosis of LS. His condition improved, including the dyspnea, and he was discharged on the proper antibiotics coverage with outpatient follow-up. Conclusions: LS is a rare condition associated with metastatic infection spreading. This syndrome can be associated with further complications, such as pleural effusions and/or empyemas. Early recognition is important to prevent fatal complications and provide adequate antibiotics coverage. We report only the third case in the medical literature of Prevotella-induced LS with a secondary complication of pleural effusion

    Neurological manifestations including psychomotor developmental delay and epilepsy in patients with Angelman syndrome caused by ubiquitin protein ligase E3A (UBE3A) mutations has been considered similar but is relatively milder than that in patients with deletion-type Angelman syndrome. This makes the diagnosis of the former subgroup often difficult. We here characterized epilepsy, specifically the types of tremulous movement, in 4 patients (age, 3-38years) with Angelman syndrome caused by UBE3A mutations. Ictal electroencephalography was used to record episodic tremors in all study patients. Jerk-locked averaging was performed using digital electroencephalography and surface electromyogram data from patients who were monitored for 24h. All patients had tremors in the limbs, head, and trunk, which resulted in 2 patients falling backward. These tremors lasted several seconds, and could emerge in clusters for hours in older patients. In addition, the tremors coincided with 7-8Hz rhythmic activity with a frontocentral predominance, diffuse spike-wave bursts, or no apparent change on electroencephalography. In 2 patients, these tremors were confirmed as cortical myoclonus using jerk-locked averaging. The other seizure types were isolated generalized myoclonus and tonic seizures. None of the patients experienced atypical absence seizures. Levetiracetam therapy was effective in controlling the myoclonic events in 2 of the 3 patients. Semirhythmic myoclonus is common in patients with Angelman syndrome caused by UBE3A mutations, and such myoclonic events are often life disabling. The preserved expression of gamma-aminobutyric acid type A receptor subunit genes located proximal to UBE3A might explain the low prevalence of absence seizures in this population.

    Full Text Available Drug rash with eosinophilia and systemic symptoms (DRESS syndrome is a severe, idiosyncratic, multi-system reaction characterized by the clinical triad of fever, rash, and internal organ involvement. The mortality rate is estimated to be 8%, especially among patients with liver involvement, so early recognition is imperative. Drugs commonly associated with the development of DRESS syndrome include anticonvulsants, long-acting sulfonamides, and anti-inflammatory medications; however, there are no reported cases implicating anti-tuberculosis (anti-TB medications. We report a case of DRESS syndrome from anti-TB therapy. A 68-year-old male with pulmonary TB presented with pruritic skin eruption and sore throat, 8 weeks after starting Rifampin, Isoniazid, Pyrazinamide, and Ethambutol (RIPE therapy. He takes metformin and glyburide for diabetes. Physical exam was significant for diffuse, exfoliative erythematous macules with target lesions involving the entire skin surface, without mucosal involvement. Laboratory data was significant for mild transaminitis and new onset eosinophilia. Given suspicion of drug eruption, RIPE therapy was discontinued. Skin biopsy confirmed erythema multiforme. Despite discontinuation of the implicated medications, eosinophilia and transaminitis continued to worsen, and so systemic corticosteroids were started. After 4 weeks of discontinuation of RIPE therapy, the cutaneous eruption resolved and laboratory data returned to normal. The patient is finishing course of anti-TB with cycloserine and moxifloxacin. Upon follow up as outpatient, the rash was resolving and disappeared in 1 month. DRESS syndrome is always considered when there is high eosinophil counts and multisystem involvement with skin eruptions. It can be potentially life threatening with certain drugs and infectious agents in predisposed individuals. It is imperative to discontinue the causative medication and avoid re-exposure.

    Melnick Needles syndrome (MNS), Treacher Collins syndrome (TCS) and Pierre Robin syndrome (PRS) are congenital abnormalities with characteristic facial appearances that include micrognathia. A 20-year-old girl with MNS, a 16-year-old boy with TCS and a 12-year-old girl with PRS attended the sleep apnoea clinic at our institution at different times. Diagnostic sleep studies were initially performed on all three patients to confirm the diagnosis of obstructive sleep apnoea syndrome (OSAS). They subsequently commenced nasal CPAP (nCPAP) treatment and their progress was followed. A limited sleep study on the patient with MNS demonstrated moderate\\/severe OSAS with an AHI of 33 events\\/h. Commencement of nCPAP resulted in symptomatic improvement. Overnight oximetry in the patient with TCS showed repeated desaturation to SpO2<90%. Subsequent treatment by nCPAP almost completely abolished the desaturation events. Overnight polysomnography in the patient with PRS demonstrated severe OSAS with an AHI of 49 events\\/h. After 3 years of nCPAP therapy, this patient requested discontinuation of treatment. Subsequent polysomnography without nCPAP revealed an AHI of <5 events\\/h. The use of nCPAP in the patients with MNS and TCS resulted in effective control of their sleep abnormalities. Mandibular growth and enlargement of the posterior airway space led to resolution of OSAS in the patient with PRS. There is a definite role for nCPAP therapy in patients with congenital micrognathia and OSAS. The use of nCPAP may obviate the need for more invasive corrective surgery for OSAS and is not necessarily a life-long requirement.

    Full Text Available Persistent hepatitis C virus (HCV infection may induce autoimmune diseases and chronic hepatitis C is sometimes accompanied by autoimmune hepatitis (AIH. However, we are worried about the treatment for chronic hepatitis C-AIH overlap syndrome because interferon-based antiviral therapies may enhance autoimmunity and immunosuppressive corticosteroid administration may promote viral replication. Here, we report a patient having chronic hepatitis C-AIH overlap syndrome treated with the direct-acting antivirals (DAA, daclatasvir and asunaprevir. A 50-year-old man was referred to our hospital because of positive anti-HCV antibody and liver dysfunction at a health checkup. Blood tests showed increased immunoglobulin G (IgG and a high titer of antinuclear antibody (ANA in addition to elevated serum alanine aminotransferase (ALT and HCV-RNA. Infiltration of lymphocytes and plasma cells in Glisson’s capsule and severe interface hepatitis were observed in biopsied specimen, which fulfilled the criteria of AIH. We first started oral corticosteroid administration, and serum ALT levels decreased once but elevated again. We commenced daclatasvir and asunaprevir (60 and 200 mg/day, respectively and serum HCV-RNA became negative after 6 weeks. Adverse effects were not found during the DAA treatment, and serum ALT, IgG, and ANA were significantly decreased. Corticosteroid could be tapered and stopped, but no recurrence occurred. DAA treatment appears to be effective and safe for the patients with chronic hepatitis C-AIH overlap syndrome.

    Spinocerebellar ataxia syndromes presenting in adulthood have a broad range of causes, and despite extensive investigation remain undiagnosed in up to ∼50% cases. Mutations in the mitochondrially encoded MTATP6 gene typically cause infantile-onset Leigh syndrome and, occasionally, have onset later in childhood. The authors report two families with onset of ataxia in adulthood (with pyramidal dysfunction and/or peripheral neuropathy variably present), who are clinically indistinguishable from other spinocerebellar ataxia patients. Genetic screening study of the MTATP6 gene in 64 pedigrees with unexplained ataxia, and case series of two families who had MTATP6 mutations. Three pedigrees had mutations in MTATP6, two of which have not been reported previously and are detailed in this report. These families had the m.9185T>C and m.9035T>C mutations, respectively, which have not previously been associated with adult-onset cerebellar syndromes. Other investigations including muscle biopsy and respiratory chain enzyme activity were non-specific or normal. MTATP6 sequencing should be considered in the workup of undiagnosed ataxia, even if other investigations do not suggest a mitochondrial DNA disorder.

    Full Text Available Brown-Vialetto-Van Laere syndrome is a rare disorder characterized by motor, sensory, and cranial neuronopathies, associated with mutations in SLC52A2 and SLC52A3 genes that code for human riboflavin transporters RFVT2 and RFVT3, respectively. The authors describe the clinical course of a 6-year-old girl with Brown-Vialetto-Van Laere syndrome and a novel homozygous mutation c.1156T>C in the SLC52A3 gene, who presented at the age of 2.5 years with progressive brain stem dysfunction including ptosis, facial weakness, hearing loss, dysphagia, anarthria with bilateral vocal cord paralysis, and ataxic gait. She subsequently developed respiratory failure requiring tracheostomy and worsening dysphagia necessitating a gastrostomy. Following riboflavin supplementation, resolution of facial diplegia and ataxia, improvements in ptosis, and bulbar function including vocalization and respiration were noted. However, her sensorineural hearing loss remained unchanged. Similar to other cases of Brown-Vialetto-Van Laere syndrome, our patient responded favorably to early riboflavin supplementation with significant but not complete neurologic recovery.

    To describe the first instance of genotyping in a Latin American family with Wolfram syndrome (WS). Four affected siblings and their healthy parents were studied. Ophthalmologic examination included best corrected visual acuity determination, funduscopy, fluorescein retinal angiography, and Goldmann kinetic perimetry. Molecular methods included linkage analysis using microsatellites markers located on the markers located on the Wofram syndrome 1 (WFS1) region at 4p16.1, PCR amplification and direct nucleotide sequencing analysis of the complete coding region and exon/intron junctions of WFS1. In addition, allele-specific cloning and sequencing techniques were used to characterize a heterozygous frameshift mutation. The four affected siblings presented with a homogeneous clinical picture characterized by early onset diabetes mellitus, severe optic atrophy, and progressive hearing loss. Linkage analysis indicated that all four sibs were heterozygous for markers linked to the WFS1 region and that each inherited the same allele from the mother and the same from the father, suggesting compound heterozygosity. Direct WFS1 analysis disclosed a paternally inherited novel missense R177P mutation whereas allele-specific cloning and sequencing revealed a novel WFS1 16 bp deletion that was inherited from the mother. Our report of two novel WFS1 mutations expands the molecular spectrum of Wolfram syndrome. This is the first documented case of the molecular basis of the disease in a Latin American family. Analysis of more patients from this population will establish if compound heterozygosity is commonly found in affected individuals from this ethnic group.

    Prolonged use of topical corticosteroids causes systemic adverse effects including Cushing's syndrome and hypothalamic-pituitary-adrenal (HPA) axis suppression, which is less common than that of the oral or parenteral route. At least 43 cases with iatrogenic Cushing syndrome from very potent topical steroid usage (Clobetasol) in children and adult have been published over the last 35 years particularly in developing countries. In children group (n = 22), most are infants with diaper dermatitis and two cases who had started topical application at a very early age and died from severe disseminated CMV infection. For the adult group (n = 21), the most common purpose of steroid use was for treatment of Psoriasis. The recovery period of HPA axis suppression was 3.49 ± 2.92 and 3.84 ± 2.51 months in children and adult, respectively. We report on an 8-month-old female infant who developed Cushing's syndrome and adrenal insufficiency after diaper dermatitis treatment through the misuse of Clobetasol without doctor's prescription. Physiologic dose of hydrocortisone was prescribed to prevent an adrenal crisis for 3 months and discontinued when HPA axis recovery was confirmed by normal morning cortisol and ACTH levels.

    Treatment of allergic bronchopulmonary aspergillosis with itraconazole is becoming more widespread in chronic lung diseases. A considerable number of patients is concomitantly treated with topical or systemic glucocorticoids for anti-inflammatory effect. As azole compounds inhibit cytochrome P450 enzymes such as CYP3A isoforms, they may compromise the metabolic clearance of glucocorticoids, thereby causing serious adverse effects. A patient with cystic fibrosis is reported who developed iatrogenic Cushing's syndrome after long-term treatment with daily doses of 800 mg itraconazole and 1,600 microg budesonide. The patient experienced symptoms of striae, moon-face, increased facial hair growth, mood swings, headaches, weight gain, irregular menstruation despite oral contraceptives and increasing insulin requirement for diabetes mellitus. Endocrine investigations revealed total suppression of spontaneous and stimulated plasma cortisol and adrenocorticotropin. Discontinuation of both drugs led to an improvement in clinical symptoms and recovery of the pituitary-adrenal axis after 3 mo. This observation suggests that the metabolic clearance of buDesonide was compromised by itraconazole's inhibition of cytochrome P450 enzymes, especially the CYP3A isoforms, causing an elevation in systemic budesonide concentration. This provoked a complete suppression of the endogenous adrenal function, as well as iatrogenic Cushing's syndrome. Patients on combination therapy of itraconazole and budesonide inhalation should be monitored regularly for adrenal insufficiency. This may be the first indicator of increased systemic exogenous steroid concentration, before clinical signs of Cushing's syndrome emerge.

    Thirty-two unrelated patients with features of Saethre-Chotzen syndrome, a common autosomal dominant condition of craniosynostosis and limb anomalies, were screened for mutations in TWIST, FGFR2, and FGFR3. Nine novel and three recurrent TWIST mutations were found in 12 families. Seven families were found to have the FGFR3 P250R mutation, and one individual was found to have an FGFR2 VV269-270 deletion. To date, our detection rate for TWIST or FGFR mutations is 68% in our Saethre-Chotzen syndrome patients, including our five patients elsewhere reported with TWIST mutations. More than 35 different TWIST mutations are now known in the literature. The most common phenotypic features, present in more than a third of our patients with TWIST mutations, are coronal synostosis, brachycephaly, low frontal hairline, facial asymmetry, ptosis, hypertelorism, broad great toes, and clinodactyly. Significant intra- and interfamilial phenotypic variability is present for either TWIST mutations or FGFR mutations. The overlap in clinical features and the presence, in the same genes, of mutations for more than one craniosynostotic condition-such as Saethre-Chotzen, Crouzon, and Pfeiffer syndromes-support the hypothesis that TWIST and FGFRs are components of the same molecular pathway involved in the modulation of craniofacial and limb development in humans.

    The 15q11q13 region is subject to imprinting and is involved in various structural rearrangements. Less than 1% of Angelman Syndrome patients are due to translocations involving 15q11q13. These translocations can arise de novo or result from the segregation of chromosomes involved in a familial balanced translocation. A 5-year-old Mexican girl presented with developmental delay, minor dysmorphic features and history of exotropia. G-banding chromosome analysis established the diagnosis of Angelman Syndrome resulting from a familial translocation t(10;15) involving the 15q11.2 region. The available family members were studied using banding and molecular cytogenetic techniques, including Microarray-based Comparative Genomic Hybridization, which revealed additional unexpected results: a coincidental and smaller 15q deletion, asymptomatic duplications in 15q11.2 and Xp22.31 regions. This report demonstrates the usefulness of array CGH for a detailed characterization of familial translocations, including the detection of submicroscopic copy number variations, which would otherwise be missed by karyotype analysis alone. Our report also expands two molecularly characterized rare patient cohorts: Angelman Syndrome patients due to familial translocations and patients with 15q11.2 duplications of paternal origin.

    Full Text Available Syndrome of inappropriate secretion of antidiuretic hormone (SIADH is an extremely rare complication of infectious diseases. A rare case of brucellosis complicated by syndrome of inappropriate secretion of antidiuretic hormone (SIADH cholestasis and pericardial involvement is reported. A 27-year-old woman was admitted for fever, abdominal pain, and scleral icterus. Her medical history revealed no recent use of diuretic agents. In addition to cholestasis and elevated liver enzymes, euvolemic hyponatremia, hypouricemia, low plasma osmolality, and high urinary osmolality were also detected. Surrenal and thyroid tests were also within normal range. Echocardiography revealed minimal pericardial effusion with normal cardiac functions. The final diagnosis was SIADH due to Brucellosis. Hyponatremia, cholestasis, and pericardial disease were resolved with effective antibrucellar treatment with streptomycine and doxycycline. After completing treatment of brucellosis, there was not any more evidence of cholestasis and pericardial fluid.

    Pituitary microadenomas and adrenal tumours are the most common causes for endogenous Cushing syndrome (CS) in children. We describe a two-year old girl with Cushing syndrome due to ectopic pro-opiomelanocortin (POMC) production from an abdominal yolk sac tumor. Cortisol concentrations were elevated but adrenocorticotropic hormone (ACTH) concentrations were equivocal. The use of antibodies specifically detecting ACTH precursors revealed that plasma ACTH precursors were elevated. Additionally, an ACTH assay with a low cross-reactivity for precursors showed low concentrations of ACTH. Immunohistochemistry suggested POMC but not ACTH production by the tumour. We describe a yolk sac tumour as a novel source of ectopic POMC production leading to CS in a young girl. © 2017 European Society of Endocrinology.

    Piriformis syndrome is an underdiagnosed extraspinal association of sciatica. Patients usually complain of deep seated gluteal pain. In severe cases the clinical features of piriformis syndrome are primarily due to spasm of the piriformis muscle and irritation of the underlying sciatic nerve but this mysterious clinical scenario is also described in lumbar spinal canal stenosis, leg length discrepancy, piriformis myofascial pain syndrome, following vaginal delivery, and anomalous piriformis muscle or sciatic nerve. In this paper, we describe piriformis and fibromyalgia syndrome in a 30-year-old young lady, an often missed diagnosis. We also focus on management of the piriformis syndrome.

    Full Text Available Tumor lysis syndrome (TLS is an oncologic emergency characterized by a combination of metabolic derangements (hyperuricemia, hyperkalemia, hyperphosphatemia, and hypocalcemia caused by rapid turnover from cell destruction in certain cancers. These metabolic derangements can lead to seizures, cardiac arrhythmias, renal failure, and death. TLS is usually seen after the initiation of chemotherapy for hematologic malignancies. TLS occurring spontaneously, without initiation of chemotherapy, is rare and its occurrence in solid tumors is rarer still. We report a case of spontaneous TLS in a patient with leiomyosarcoma of the uterus, with metastasis to lung. Such a case has never been reported before.

    Fracture of the first rib with ensuing callus formation is a rare cause of thoracic outlet syndrome. We report a case of a 17-year-old female volleyball player who presented with months of chronic arm pain. Radiographic imaging demonstrated nonunion fracture of the first rib. Physical therapy had been unsuccessful in relieving the pain, and surgical management was performed with resection of the first rib through a transaxillary approach with complete resolution of symptoms. Inflammation surrounding such fractures may destroy tissue planes, making dissection more technically difficult.

    We report a patient with intracranial hemorrhage secondary to venous hypertension as a result of a giant aortic pseudoaneurysm that compressed the superior vena cava and caused obstruction of the venous return from the brain. To our knowledge, this is the first patient reported to have an intracranial hemorrhage secondary to a superior vena cava syndrome. The condition appears to be caused by a reversible transient rise in intracranial pressure, as a result of compression of the venous return from the brain. Treatment consisted of surgery for the aortic pseudoaneurysm, which led to normalization of the intracranial pressure and resorption of the intracranial hemorrhage. Copyright © 2012 Elsevier Ltd.

    Coronaviruses have been demonstrated to contribute substantially to respiratory tract infections among the child population. Though infected children commonly present mild upper airway symptoms, in high-risk patients with underlying conditions, particularly in immunocompromised children these pathogens may lead to severe lung infection and extrapulmonary disorders. In this paper, we provide the first report of the case of a 15-month-old child with severe combined immunodeficiency and coronavirus HKU1-related pneumonia with fatal respiratory distress syndrome. © 2012 John Wiley & Sons Ltd.

    2014-01-01

    Bonding to root canal dentin may be difficult due to various factors: the structural characteristic of the root canal dentin, which is different from that of the coronal dentin; the presence of the organic tissue of the dental pulp inside the root canal, which has to be removed during the cleaning-shaping of the root canal system; the smear-layer resulted after mechanical instrumentation, which may interfere with the adhesion of the filling materials; the type of the irrigants used in the cleaning protocol; the type of the sealer and core material used in the obturation of the endodontic space; the type of the materials used for the restoration of the endodontically treated teeth. The influence of the cleaning protocol, of the root canal filling material, of the type of the adhesive system used in the restoration of the treated teeth and of the region of the root canal, on the adhesion of several filling and restorative materials to root canal dentin was evaluated in the push-out bond strength test on 1-mm thick slices of endodontically treated human teeth. The results showed that all these factors have a statistically significant influence on the push-out bond strength. Formation of resin tags between radicular dentin and the investigated materials was observed in some of the samples at SEM analysis.

    "Sick building syndrome" (SBS) is a group of symptoms experienced by people working in various buildings. This or another term "building-related illness" (BRI) is used to define illnesses related to modern buildings, mainly offices, in which people spend many working hours. SBS applies to a group of diseases with a fairly homogenous clinical picture and etiology (specific - infectious, allergic and non-specific--for example irritant symptoms). A case of a 51-year-old non-smoking female office worker is reported. After having her working premise renovated, she started to suffer from irritation of mucous membrane of the throat, sore throat and dysphonia. She claimed that these symptoms were associated with exposure to pentachlorophenol (PCP) emitted by the elements of ceiling impregnated with PCP-containing varnish. The concentration of PCP was below the hygiene standards adopted for the work environment. There were no grounds for recognizing occupational intoxication, but the case met the criteria for the sick building syndrome.

  11. Burning Mouth Syndrome due to Television Moans, an Enigma for Oral Physician: Treatment with Counseling

    2014-06-01

    Full Text Available Burning mouth syndrome (BMS is a relatively common disease that can severely affect the quality of life of the patient. It causes chronic orofacial pain or oral burning sensation even in the absence of any detectable organic cause. The etiology of BMS is complex and multifactorial. It has been associated with menopause, trigger events and even genetic polymorphisms. Although its etiology remains unclear, there is still much evidence that psychological elements like stress, anxiety or depression do play a significant role. There are several studies in the literature which only report the association of BMS with psychological factors. But to the best of our knowledge, there is no such case reported in the literature which has actually highlighted the management of such a case with psychogenic elements involved. In this case report, apart from discussing the role of psychological factors, the treatment of BMS with emphasis on counseling is also emphasized. Further, it is of interest to know that such patients with psychologically induced burning mouth syndrome have to be evaluated to their deepest details. Even their commonly overlooked gestures and habits like watching a particular television soap opera may be involved in their disease process. It can be concluded that psychological counseling in general dental practice can provide an effective cure for chronic oral burning sensation with psychological factors involved.

    Angelman syndrome (AS) is characterized by severe intellectual disability, limited, or absent speech and a generally happy demeanor. The four known etiological mechanisms; deletions, uniparental disomy, imprinting defects, and UBE3A mutation all affect expression of the UBE3A gene at 15q11-q13. An atypical phenotype is seen in individuals who are mosaic for a chromosome 15q11-q13 imprinting defect on the maternal allele. These patients present with a milder phenotype, often with hyperphagia and obesity or non-specific intellectual disability. Unlike typical AS syndrome, they can have a vocabulary up to 100 words and speak in sentences. Ataxia and seizures may not be present, and the majority of individuals do not have microcephaly. Here we review the current literature and present three individuals with atypical AS caused by a mosaic imprinting defect to demonstrate why DNA methylation analysis at the SNRPN locus needs to be considered in a broader clinical context. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    Full Text Available In pregnancy, advanced vertebral hemangiomas may be seen, and these require treatment. The case reported here is of a 35-year-old female in the 32nd week of pregnancy who was admitted to the orthopaedics clinic with a history of backache and difficulty walking. A burst fracture of L1 associated with a vertebral hemangioma was identified with an L3 compression fracture secondary to osteoporosis. The local kyphosis angle between T12 and L2 was 27°. Kyphotic deformity was corrected and postoperatively, the measured T12–L2 local kyphotic angle was 9°. Twelve hours postoperatively, oral nutrition was allowed, but she developed nausea and vomiting and twenty-four hours postoperatively, an electrolyte imbalance developed. Postoperatively, the patient was diagnosed with superior mesenteric artery syndrome. To the best of our knowledge, this is the first reported case of superior mesenteric artery syndrome, which occurred following the correction of a kyphotic deformity that had developed secondary to an advanced hemangioma in pregnancy.

    Pheochromocytomas in pregnancy are rare but potentially lethal. Even rarer is the combination of pheochromocytoma in pregnancy with subsequent development of ectopic Cushing's syndrome. We report a 36-year-old woman, previously diagnosed with essential hypertension, who developed severe hypertension in pregnancy complicated by insulin-dependent gestational diabetes. A cesarean section was performed at 32 weeks following a hypertensive crisis after routine administration of betamethasone. Postnatal persistence of signs and symptoms of catecholamine excess led to the diagnosis of a left adrenal pheochromocytoma. Between diagnosis and planned tumor removal, the patient developed signs and symptoms of Cushing's syndrome (facial edema and hirsutism, myopathy and fatigue). Biochemical testing confirmed hypercortisolism with extremely elevated levels of plasma adrenocorticotropin, urinary cortisol and multiple steroids of a plasma panel that were all normal at previous testing. The previously noradrenergic tumor also started producing epinephrine. Histopathological examination confirmed the pheochromocytoma, which was also immunohistochemically positive for adrenocorticotropin. Full post-surgical recovery was sustained with normal blood pressure and biochemical findings after one year. This report not only underlines the chameleon behavior of pheochromocytoma but also illustrates its potential for a metamorphosing presentation. Corticosteroid administration in pregnancy requires a cautious approach in patients with hypertension.

    CoQ transfers electrons from complexes I and II of the mitochondrial respiratory chain to complex III. There are very few reports on human CoQ deficiency. The clinical presentation is usually characterized by: epilepsy, muscle weakness, ataxia, cerebellar atrophy, migraine, myogloblinuria and developmental delay. We describe a patient who presented with neonatal liver and pancreatic insufficiency, tyrosinemia and hyperammonemia and later developed sensorineural hearing loss and Leigh syndrome. Liver biopsy revealed markedly reduced complex I+III and II+III. Addition of CoQ to the liver homogenate restored the activities, suggesting CoQ depletion. Histological staining showed prominent bridging; septal fibrosis and widening of portal spaces with prominent mixed inflammatory infiltrate, associated with interface hepatitis, bile duct proliferation with numerous bile plugs. Electron microscopy revealed a large number of mitochondria, which were altered in shape and size, widened and disordered intercristal spaces. This may be the first case of Leigh syndrome with liver and pancreas insufficiency, possibly caused by CoQ responsive oxphos deficiency.

    Myoclonic status in nonprogressive encephalopathy (MSNE) is an early-onset, drug-resistant epileptic syndrome characterized by occurrence of continuous diffuse epileptiform abnormalities, associated with positive and/or negative phenomena and accompanied by transient and recurring motor, cognitive, and behavioral impairment. MSNE has been reported in Angelman syndrome (AS) secondary to 15q11-13 deletions or UBE3A mutations but not to paternal uniparental disomy (UPD). We describe the case of a male patient with AS caused by UPD who developed a myoclonic status (MS) associated with long-lasting fever of central origin, both promptly regressed with introduction of levetiracetam. Only three descriptions of thermal dysregulation in AS exist, and none of the previously reported cases were associated with MS or with UPD. Association of MS and central fever expands the spectrum of epileptic and non-epileptic features in UPD-related AS and provides a further evidence of hypothalamus involvement in the pathogenesis of this neurodevelopmental disorder.

    Postoperative hemorrhage is a significant cause of morbidity and mortality following liver resection. It typically presents early within the postoperative period, and conservative management is possible in the majority of cases. We present a case of late post-hepatectomy hemorrhage associated with overt abdominal compartment syndrome resulting from a localized functional compartment within the abdomen. A 68-year-old white man was readmitted with sudden onset of upper abdominal pain, vomiting, and hemodynamic instability 8 days after an uneventful hepatic resection for metachronous colon cancer metastasis. A frozen abdomen with adhesions due to complicated previous abdominal surgeries was encountered at the first intervention, but the surgery itself and initial recovery were otherwise unremarkable. Prompt response to fluid resuscitation at admission was followed by a computed tomography of his abdomen that revealed active arterial hemorrhage in the liver resection site and hemoperitoneum (estimated volume compartment syndrome. Surgical exploration confirmed a small volume of ascites and blood clots (1.2 L) under significant pressure in his supramesocolic region, restricted by his frozen lower abdomen, which we evacuated. Dramatic improvement in his ventilatory pressure was immediate. His abdomen was left open and a negative pressure device was placed for temporary abdominal closure. The fascia was formally closed after 48 hours. He was discharged home at postoperative day 6. Intra-abdominal pressure and radiologic findings of intra-abdominal hemorrhage should be carefully interpreted in patients with extensive intra-abdominal adhesions. A high index of suspicion and detailed understanding of abdominal compartment mechanics are paramount for the timely diagnosis of abdominal compartment syndrome in these patients. Clinicians should be aware that abnormal anatomy (such as adhesions) coupled with localized pathophysiology (such as hemorrhage) can create a so

    Rubella virus infection during the first trimester of pregnancy can cause congenital rubella syndrome (CRS). We aimed to describe the abnormalities in order to define the ultrasound features to look for when performing prenatal scans. The goal of this review is to focus specifically on the signs of CRS accessible to prenatal diagnosis. We analyzed every case of CRS described before and/or after birth that we identified in the Pubmed database and classified them as accessible or not to prenatal diagnosis. The most frequently reported malformations accessible to prenatal diagnosis were: cardiac septal defects, pulmonary artery stenosis, microcephaly, cataract, microphtalmia, and hepatosplenomegaly. This extensive literature review shows that the ultrasound features of CRS are not well known, even though rubella was the first teratogenic virus described. This review will help clinicians in the management of rubella during pregnancy by clarifying the findings to be sought.

    Cockayne syndrome (CS) is a human premature aging disorder associated with neurological and developmental abnormalities, caused by mutations mainly in the CS group B gene (ERCC6). At the molecular level, CS is characterized by a deficiency in the transcription-couple DNA repair pathway. To understand the role of this molecular pathway in a pluripotent cell and the impact of CSB mutation during human cellular development, we generated induced pluripotent stem cells (iPSCs) from CSB skin fibroblasts (CSB-iPSC). Here, we showed that the lack of functional CSB does not represent a barrier to genetic reprogramming. However, iPSCs derived from CSB patient's fibroblasts exhibited elevated cell death rate and higher reactive oxygen species (ROS) production. Moreover, these cellular phenotypes were accompanied by an up-regulation of TXNIP and TP53 transcriptional expression. Our findings suggest that CSB modulates cell viability in pluripotent stem cells, regulating the expression of TP53 and TXNIP and ROS production.

    We have studied a patient with complete androgen insensitivity syndrome (CAIS) and a 46, inv(X),Y karyotype. The patient's mother and maternal aunt also carry the inverted X, and the mother is phenotypically normal, with a 46, inv(X),X karyotype, while a maternal aunt has CAIS with a 46,inv(X),Y karyotype. Molecular cytogenetic studies demonstrate that one of the X inversion breakpoints occurs within Xq11.2-12, which is the locus for the androgen receptor. FISH analysis demonstrated that a BAC clone containing the androgen receptor gene was disrupted by the inversion. We therefore hypothesize that disruption of the androgen receptor gene causes CAIS in this patient. This is the first report of CAIS caused by a chromosome inversion. Copyright 2003 Wiley-Liss, Inc.

    Full Text Available A 15-year-old girl who was previously diagnosed to have primary hypothyroidism presented to the outpatient department in our tertiary care centre in Southern India with abdominal distension and pedal oedema. On evaluation, she was found to have elevated lactate dehydrogenase (LDH and CA 125 levels, enlarged multicystic ovaries, ascites, and pleural and pericardial effusions. A diagnosis of spontaneous ovarian hyperstimulation syndrome (SOHSS was made based on the characteristic soap bubble-like imaging appearance of ovaries in the background of hypothyroidism and she was started on thyroxine. At her three-month follow-up, the patient’s biochemical parameters normalised with reduced ovarian volume and resolution of other imaging findings. SOHSS needs to be considered in patients with hypothyroidism and characteristic multicystic ovarian enlargement.

    Full Text Available Although posterior reversible encephalopathy syndrome (PRES is rarely associated with subarachnoid hemorrhage, to our knowledge, rupture of a concomitant cerebral aneurysm following PRES has not been reported. We describe a patient with atypical PRES involving the brainstem, thalamus, and periventricular white matter without cortical or subcortical edema of the parietooccipital lobe on magnetic resonance imaging, with rupture of a concomitant cerebral aneurysm. Preexisting extremely high blood pressure may trigger atypical PRES, and failure to lower blood pressure may lead to a concomitant aneurysm rupture. In the future treatment of hypertensive urgency with a recurrence of symptoms and mean arterial blood pressure >150 mmHg, it is advisable to immediately hospitalize the patient for aggressive blood pressure management, especially if PRES is suspected based on clinical and radiological features.

    Hyperventilation syndrome (HVS) often occurs under stressful conditions, and has been reported during or after anesthesia and operation. HVS, characterized by multiple somatic symptoms and electrolyte imbalances induced by inappropriate hyperventilation, should be managed as an emergency. We report a rare case of HVS during spinal anesthesia. The patient was a previously healthy 51-year-old female without psychogenic conditions. During spinal anesthesia for lower extremity surgery, the patient complained of nausea, headache, paresthesia in the upper extremities and perioral numbness. We found carpal spasm in both hands and flattening of T wave on electrocardiogram (ECG). Emergent arterial blood gas analysis (ABGA) revealed markedly decreased PaCO(2), hypocalcemia and hypokalemia. We managed the patient with verbal sedation, electrolytes replacement therapy and closed mask inhalation. HVS subsided gradually. We conclude that monitoring for possible HVS during anesthesia is very important for patient safety.

    Ritonavir is commonly used in low doses to boost plasma levels of protease inhibitors in patients with human immunodeficiency virus (HIV) infections. It is also a potent inhibitor of cytochrome P450. We present a 50-year-old African American male with past medical history of HIV on highly active antiretroviral therapy (HAART), which also included ritonavir and long standing asthma that has been treated with inhaled fluticasone, who presented with back pain. He had central obesity, prominent abdominal striae and wasted extremities on physical examination. Laboratory tests showed low morning serum cortisol and suboptimal cosyntropin test consistent with adrenal insufficiency. Computed tomography (CT) of the spine showed a fracture of inferior endplate of the lumbar (L3) vertebra. The cause of osteoporosis is believed to be iatrogenic Cushing syndrome caused by enhanced levels of inhaled fluticasone effects secondary to inhibition of cytochrome P450. The patient was managed surgically and fluticasone was discontinued.

    Full Text Available ABSTRACT We report one patient with Klippel-Feil (KFS syndrome, other associated anomalies, uncontrolled arterial hypertension, and renal artery stenosis. Because this patient underwent for surgical revascularization with unsuccessful result, all proposed way of treatments are revised, and we have hypothesized that probably for patients with KFS and unilateral renal artery stenosis, medical treatment with ACE inhibitors can provide more benefits than surgical revascularization or percutaneous transluminal angioplasty. We considered that those patients should be manage by a team of medical doctors being aware of their common associated anomalies, identifying all of them when it is possible then, making an integral evaluation of the each individual situation for establishing their medical priorities in order, and then address its treatments accordingly. If at this stage any surgical treatment is required, is important to bring those problems to the anesthesiologist’s attention for a very careful manipulation of the neck and head during induction of anesthesia. The final results will be strongly related with the capacity of management of the underlying cardio-respiratory, renal, skeletal, urogenital, and nervous system problems. . We also propose the term of Klippel-Feil syndrome "Plus" for those patients with cervical vertebral fusion and many other associated deformities rather than to add new eponyms to the long list that already exist. _____________ RESUMEN: HIPERTENSION RENOVASCULAR DEBIDO A ESTENOSIS DE LA ARTERIA RENAL EN EL SÍNDROME DE KLIPPEL-FEIL Reportamos un paciente afectado por un syndrome de Klippel-Feil, otras anormalias congenitas, hipertension arterial incontrolada y una estenosis unilateral de la arteria renal.

    Acute thyroiditis is an extremely rare complication of nocardiosis. We report a patient with hyperthyroidism due to suppurative thyroiditis caused by Nocardia brasiliensis. A 38-year-old Black male presented with features of thyrotoxicosis, sepsis and airway obstruction. He had no evidence of underlying thyroid disease, but was severely immunocompromised as a result of acquired immunodeficiency syndrome. He had previously been diagnosed with pulmonary nocardiosis and also had nocardial abscesses on his anterior chest wall. Investigations revealed thyrotoxicosis, with a FT4 of 43.2 pmol/l and a suppressed TSH Nocardia.

    Purpose Prader-Willi syndrome (PWS) is an imprinting disorder characterized by typical facial, physical and cognitive/behavioral features, resulting from lack of paternally-expressed genes on chromosome 15q11.2-q13. Studies have suggested an increased risk of other imprinting disorders in children conceived by assisted reproductive techniques (ART). This study was designed to determine the association between ART and PWS. Methods Data on individuals with PWS were collected from three distinct sources and the proportion of ART-births analyzed. Results The proportion of ART-births in the Prader-Willi Syndrome Association [PWSA (USA)], Rare Diseases Clinical Research Network (RDCRN), and University of California, Irvine Medical Center (UCIMC) populations was 1.0% (18/1,736), 1.0% (1/98), and 2.0% (1/50), respectively (overall 1.1%; population frequency for the U.S was 1.0%). Interestingly, 2.4% (45/1,898) of participants were co-twins (eleven born after ART procedures); U.S. twin frequency is 1.6% (p=0.007). The proportion of individuals with maternal disomy 15/imprinting defects born after ART was higher than in the total sample, 55.6% (10/18) and 34.5% (431/1,250), respectively. Conclusion This study found no association between ART and PWS. There was an increased frequency of twinning. The number of individuals with maternal disomy 15/imprinting defect was nearly double in the ART group compared to the total PWS participants. PMID:23928912

    Uniparental isodisomy arises when an individual inherits two copies of a specific chromosome from a single parent, which can unmask a recessive mutation or cause a problem of genetic imprinting. Here we describe an exceptional case in which the patient simultaneously presents tyrosinemia type 1 and Angelman syndrome. The genetic studies showed that the patient presents paternal uniparental isodisomy of chromosome 15, with absence of the maternal homolog. As a consequence of this isodisomy, the patient is homozygous for the mutation IVS12+5G>A in the FAH gene, located in the chromosomal region 15q23-25, causing tyrosinemia type 1. The mutation was inherited from his father in double dosage, whereas the mother is not a carrier, which implies that the recurrence risk in the family is negligible. On the other hand, the lack of maternal contribution causes Angelman syndrome, a neurodevelopmental disorder associated with a loss of maternal gene expression in chromosome region 15q11-q13, and more specifically, of the UBE3A gene. This gene shows a tissue-specific imprinting, and only the maternally derived allele is expressed in certain areas of the brain. We observed through a literature review that uniparental disomy probably occurs more frequently than suspected, although it is more usually detected when the uniparental disomy implies the appearance of a disease because of the gene imprinting or by reduction to homozygosity of a recessive mutation. The conclusion is that uniparental disomy should always be considered when more than one genetic disease mapping to the same chromosome is present in a patient.

    To evaluate the clinical, CT and MR imaging findings of semicircular canal (SCC) aplasia and to evaluate if a correlation exists between these findings and the associated anomalies or syndromes. This study retrospectively reviewed the CT and MRI findings of five patients with SCC aplasia. The CT and MR findings were analyzed for SCC, direction of facial nerve canal, cochlea, vestibule, oval or round window, middle ear ossicles, and internal auditory canal (IAC). The subjects included three boys and two girls ranging in age from one to 120 months (mean age; 51 months). Four of the subjects had the CHARGE syndrome, and one had the Goldenhar syndrome. Moreover, four subjects had sensorineural hearing loss and one had combined hearing loss. The course of the facial nerve canal was abnormal in all five cases. Moreover, trapped cochlea and dysplastic modiolus were each observed in one case. Four subjects had atresia of the oval window; whereas ankylosis of the ossicles was present in three subjects. IAC stenosis was present in one patient with the CHARGE syndrome. The aberrant course of the facial nerve canal, atresia of the oval window, and abnormal ossicles were frequently associated in patients with SCC aplasia. In addition, the Goldenhar and CHARGE syndromes were also commonly associated syndromes.

    Full Text Available Abstract Introduction Lemierre's syndrome was originally documented to be caused by Fusobacterium necrophorum. It is a very rare condition with a prevalence of one to 14.4 instances per million. Its presentation is varied, not only in composition but also in the infecting organism. Treatment with anticoagulants has been controversial and applied only on a case-by-case basis. Case presentation A 63-year-old Saudi man who had had uncontrolled diabetes mellitus for 47 years presented to our facility with a five-day history of swelling on the right side of his neck and fever. The swelling progressively increased in size and was associated with pain, dysphagia, odynophagia, change of voice ('hot potato voice', and reduced appetite. Abscess content culture and sensitivity testing revealed Klebsiella pneumoniae. However, blood culture results were repeatedly negative. The abscess was incised and drained without any complication. Our patient was treated with clindamycin and cefuroxime. Warfarin was also administered concurrently for six weeks, for an isolated internal jugular vein thrombosis (IJV, with complete resolution of the thrombus. Normoglycemia was achieved and our patient was discharged after complete wound healing and the return of his biochemical parameters to normal. Conclusions Only two cases of Lemierre's syndrome in patients with diabetes due to K. pneumoniae have been reported previously. A review of the literature suggested that an association exists between deep neck infections due to K. pneumoniae and diabetes mellitus. The reasons for this association are still not clear. This poses a question as to whether diabetes mellitus specifically predisposes these patients to infection with this organism. It is suggested that clinicians should consider infectious agents other than F. necrophorum in the causation of Lemierre's syndrome, especially in patients with diabetes.

  15. Is Disturbed Transfer of Learning in Callosal Agenesis due to a Disconnection Syndrome?

    Full Text Available Disturbed intermanual transfer of tactile learning in callosal agenesis has been interpreted as a sign of disconnection syndrome. We observed this sign in one of four acallosal patients with a conventional form-board task, and tried to elucidate the nature of the deficit. The form-board performance of the patient with disturbed transfer of learning totally depended on motor skill, while the other acallosals and normal controls executed the task based on spatial and somesthetic information. All acallosals and normals, however, failed to show transfer of learning with another tactile task which needed motor skill but not spatial-somesthetic information. These findings suggest that the task-performing strategies in form-board learning change the state of interhemispheric transfer. Unimanual learning effect is transferred if spatial-somesthetic information is acquired in the process of learning, but is not transferred if motor skill is the exclusive content of learning. We conclude that disturbed “transfer” of learning in some acallosals is not a true disconnection sign. It should be attributed to a lack of appropriate strategy, as a result of ineffective problem solving in tactile tasks.

    Full Text Available We report on 4 cases of abdominal compartment syndrome complicated by acute renal failure that were promptly reversed by different abdominal decompression methods. Case 1: A 57-year-old obese woman in the post-operative period after giant incisional hernia correction with an intra-abdominal pressure of 24 mm Hg. She was sedated and curarized, and the intra-abdominal pressure fell to 15 mm Hg. Case 2: A 73-year-old woman with acute inflammatory abdomen was undergoing exploratory laparotomy when a hypertensive pneumoperitoneum was noticed. During the surgery, enhancement of urinary output was observed. Case 3: An 18-year-old man who underwent hepatectomy and developed coagulopathy and hepatic bleeding that required abdominal packing, developed oliguria with a transvesical intra-abdominal pressure of 22 mm Hg. During reoperation, the compresses were removed with a prompt improvement in urinary flow. Case 4: A 46-year-old man with hepatic cirrhosis was admitted after incisional hernia repair with intra-abdominal pressure of 16 mm Hg. After paracentesis, the intra-abdominal pressure fell to 11 mm Hg.

    Full Text Available Severe pulmonary involvement in malaria has been frequently reported in cases of Plasmodium falciparum infection, but rarely in vivax malaria. Among the 11 previous cases of vivax-related severe respiratory involvement described in the literature, all except one developed it after the beginning of anti-malarial treatment; these appear to correspond to an exacerbation of the inflammatory response. We report the case of a 43-year-old Brazilian woman living in a malaria-endemic area, who presented acute respiratory distress syndrome (ARDS caused by P. vivax before starting anti-malarial treatment. The diagnosis was made based on microscopic methods. A negative rapid immunochromatographic assay, based on the detection of Histidine Rich Protein-2 (HRP-2 of P. falciparum, indicated that falciparum malaria was unlikely. After specific anti-plasmodial therapy and intensive supportive care, the patient was discharged from the hospital. We conclude that vivax malaria-associated ARDS can develop before anti-malarial therapy.

    Full Text Available Congenital myasthenic syndromes (CMS are neuromuscular transmission disorders caused by mutations in genes encoding neuromuscular junction proteins. A 61-year-old female and her older sister showed bilateral ptosis, facial and proximal limb weakness, and scoliosis since childhood. Another female sibling had milder signs, while other family members were asymptomatic. Facial nerve repetitive stimulation in the proband showed decrement of muscle responses. Single fiber EMG revealed increased jitter and blocking. Muscle biopsy showed type 2-fiber atrophy, without tubular aggregates. Mutational analysis in the three affected siblings revealed two compound heterozygous mutations in DOK7: c.1457delC, that predicts p.Pro486Argfs*13 and truncates the protein C-terminal domain, and c.473G>A, that predicts p.Arg158Gln and disruption of the dok7-MuSK interaction in the phosphotyrosine binding (PTB domain. Unaffected family members carried only one or neither mutation. Discussion. Two of the affected sisters showed marked improvement with salbutamol treatment, which illustrates the benefits of a correct diagnosis and treatment of DOK7-CMS.

    Maternal uniparental disomy (UPD) 15 is one of the molecular causes of Prader-Willi syndrome (PWS), a multisystem disorder which presents with neonatal hypotonia and feeding difficulty. Current diagnostic algorithms differ regarding the use of SNP microarray to detect PWS. We retrospectively examined the frequency with which SNP microarray could identify regions of homozygosity (ROH) in patients with PWS. We determined that 7/12 (58%) patients with previously confirmed PWS by methylation analysis and microsatellite-positive UPD studies had ROH (>10 Mb) by SNP microarray. Additional assessment of 5,000 clinical microarrays, performed from 2013 to present, determined that only a single case of ROH for chromosome 15 was not caused by an imprinting disorder or identity by descent. We observed that ROH for chromosome 15 is rarely incidental and strongly associated with hypotonic infants having features of PWS. Although UPD microsatellite studies remain essential to definitively establish the presence of UPD, SNP microarray has important utility in the timely diagnostic algorithm for PWS. © 2017 S.

  20. Occult Breast Cancer due to Multiple Calcified Hamartomas in a Patient with Cowden Syndrome

    E. B. Gómez García

    2012-01-01

    Full Text Available Cowden syndrome (CS is an autosomal dominant disorder characterized by presence of multiple hamartomas, and other benign and malignant abnormalities of the breasts, skin, thyroid, endometrium, gastrointestinal tract, and central nervous system. Hamartomas are benign, developmentally disorganized tumors that can develop in any of the above mentioned organs. The presence of massive calcifications in the breasts in very young women is an indication to perform a breast MRI to exclude a neoplasm since, like in the current case report, presence of breast calcifications may obscure a neoplasm. Although fibrocystic disease and cooccurrence of fibrocystic disease and breast cancer are much more common than CS, the presence of massive calcifications in the breasts of very young women should elicit the possibility of an underlying genetic disease. Furthermore, breast cancer and macrocephaly are considered major criteria for the diagnosis of CS and the combination of both is enough to establish the clinical diagnosis of this entity. Fibrocystic disease of the breasts and multinodular goiter are minor criteria. Family history is also important for the diagnosis of (any hereditary disease.

    Severe acute respiratory symptoms with coughing, dyspnea, and gasping were reported in two flocks of 9-day-old Pekin ducklings from different provinces. Gross lesions, white exudate and mucous membrane congestion in the trachea as well as blue to purple color changes and sclerosis in lungs were observed. Histological lesions revealed that the trachea and bronchial epithelium were hyperplastic and infiltrated by neutrophil granulocytes. Egg drop syndrome virus (EDSV) was differentially diagnosed using polymerase chain reaction, and the strains were isolated from tracheas and lungs by inoculation of 10-day-old embryonated duck eggs. The virus isolates were designated strain D11-JW-012 and D11-JW-017. The clinical and pathological signs were reproduced by intra-tracheal inoculation of the isolates in 3-day-old ducklings. Although the two isolates produced similar clinical signs, pathological lesions and ciliostasis, the D11-JW-017 strain resulted in more severe clinical signs with progressive symptoms compared to those of D11-JW-012 strain-infected ducklings. We suggest that different EDSV strains with mild or severe to moderate pathogenicity coexist and have potential risks in poultry. Hereby, we report an EDSV infection in ducklings.

    Full Text Available In this study, we report an endodontic treatment of the maxillary second premolar with three root canals and distinct foramens. The possibility of three root canals in this tooth is quite small; however, it must be taken into account in clinical and radiographic evaluation during endodontic treatment. Many times, their presence is noticed only after canal treatment due to continuing post-operative discomfort.

    Purpose. To determine the disease course in Usher syndrome type IB (USH1B) caused by myosin 7A (MYO7A) gene mutations. Methods. USH1B patients (n = 33, ages 2–61) representing 25 different families were studied by ocular examination, kinetic and chromatic static perimetry, dark adaptometry, and optical coherence tomography (OCT). Consequences of the mutant alleles were predicted. Results. All MYO7A patients had severely abnormal ERGs, but kinetic fields revealed regional patterns of visual loss that suggested a disease sequence. Rod-mediated vision could be lost to different degrees in the first decades of life. Cone vision followed a more predictable and slower decline. Central vision ranged from normal to reduced in the first four decades of life and thereafter was severely abnormal. Dark adaptation kinetics was normal. Photoreceptor layer thickness in a wide region of central retina could differ dramatically between patients of comparable ages; and there were examples of severe losses in childhood as well as relative preservation in patients in the third decade of life. Comparisons were made between the mutant alleles in mild versus more severe phenotypes. Conclusions. A disease sequence in USH1B leads from generally full but impaired visual fields to residual small central islands. At most disease stages, there was preserved temporal peripheral field, a potential target for early phase clinical trials of gene therapy. From data comparing patients' rod disease in this cohort, the authors speculate that null MYO7A alleles could be associated with milder dysfunction and fewer photoreceptor structural losses at ages when other genotypes show more severe phenotypes.

    Menstrual irregularity and above-average testosterone levels in adolescence may presage polycystic ovary syndrome (PCOS) in adulthood but persist in only a minority. Prolonged anovulatory cycles in normal adolescents are associated with increased testosterone levels. Thus, questions have been raised about the accuracy of PCOS diagnosed in adolescents. The purpose of this study was to follow-up hyperandrogenic adolescents with features of PCOS to test the hypothesis that adolescent functional ovarian hyperandrogenism (FOH) persists into adulthood. A series of adults previously reported to have adolescent PCOS, with most documented to have FOH by GnRH agonist or dexamethasone androgen-suppression test criteria, were recalled. Recall occurred >3 years after the initial diagnosis and at the age of >18.0 years. Respondents underwent examination, baseline androgen evaluation, and an oral glucose tolerance test after discontinuing oral contraceptive therapy. Of the adolescent hyperandrogenic patients, 68% (15 of 22) were traceable, and 60% of those traced returned for follow-up, including half (n = 8) of the original FOH group. The baseline characteristics of respondents and nonrespondents were not significantly different. Patients with FOH were reevaluated when their mean age was 23.0 years (range, 18.4-29.4 years), gynecologic age was 10.7 years (range, 5.5-18.4 years), and body mass index was 42.3 kg/m(2) (range, 28.3-52.1 kg/m(2); P = .02 vs adolescence). Serum free testosterone was 24 pg/mL (range, 10-38 pg/mL, normal, 3-9 pg/mL; not significant vs adolescence); all were oligomenorrheic. Whereas 3 of 8 had impaired glucose tolerance as adolescents, at follow-up 6 of 8 had developed abnormal glucose tolerance (2 with type 2 diabetes mellitus). Adolescents with FOH, which underlies most PCOS, uniformly have persistent hyperandrogenism, and glucose tolerance tends to deteriorate. Testing ovarian androgenic function in hyperandrogenic adolescents may be of prognostic

    2008-01-01

    Full Text Available A 70-year-old male patient developed acute paraplegia due to conus medullaris compression secondary to extrusion of D12-L1 disc. After negative epidural examination intraoperatively, a durotomy was performed and an intradural disc fragment was excised. Patient did not regain ambulatory status at two-year follow-up. Intraoperative finding of negative extradural compression, tense swollen dura and CSF leak from ventral dura should alert the surgeon for the possibility of intradural disc herniation. A routine preoperative MRI is misleading and a high index of suspicion helps to avoid a missed diagnosis.

    Crew health and performance may be impacted by a major solar particle event (SPE), multiple SPEs, or the cumulative effect of galactic cosmic rays (GCR) and SPEs. Beyond low-Earth orbit, the protection of the Earth's magnetosphere is no longer available, such that increased shielding and protective mechanisms are necessary in order to prevent acute radiation sickness and impacts to mission success or crew survival. While operational monitoring and shielding are expected to minimize radiation exposures, there are EVA scenarios outside of low-Earth orbit where the risk of prodromal effects, including nausea, vomiting, anorexia, and fatigue, as well as skin injury and depletion of the blood-forming organs (BFO), may occur. There is a reasonable concern that a compromised immune system due to high skin doses from a SPE or due to synergistic space flight factors (e.g., microgravity) may lead to increased risk to the BFO. The primary data available at present are derived from analyses of medical patients and persons accidentally exposed to acute, high doses of low-linear energy transfer (LET) (or terrestrial) radiation. Data more specific to the space flight environment must be compiled to quantify the magnitude of increase of this risk and to develop appropriate protection strategies. In particular, information addressing the distinct differences between solar proton exposures and terrestrial exposure scenarios, including radiation quality, dose-rate effects, and non-uniform dose distributions, is required for accurate risk estimation.

    2010-07-01

    To estimate breed-specific risk of death due to, and prevalence of, gastric dilatation-volvulus (GDV) in UK pedigree dogs. Data were available on the reported cause of and age at death and occurrence of and age at diagnosis of disease from the 2004 purebred dog health survey. A total of 15,881 dogs of 165 breeds had died in the previous 10 years; GDV was the cause of death in 65 breeds. There were 36,006 live dogs of 169 breeds of which 48 breeds had experienced > or =1 episodes of GDV. Prevalence ratios were used to estimate breed-specific GDV mortality and morbidity risks. Gastric dilatation-volvulus was the cause of death for 389 dogs, representing 2.5% (95% CI: 2.2-2.7) of all deaths reported and the median age at death was 7.92 years. There were 253 episodes in 238 live dogs. The median age at first diagnosis was five years. Breeds at greatest risk of GDV mortality were the bloodhound, Grand Bleu de Gascogne, German longhaired pointer and Neapolitan mastiff. Breeds at greatest risk of GDV morbidity were the Grand Bleu de Gascogne, bloodhound, otterhound, Irish setter and Weimaraner. These results suggest that 16 breeds, mainly large/giant, are at increased risk of morbidity/mortality due to GDV.

    We report on an infant who had been prenatally diagnosed with Klinefelter syndrome associated with a "de novo" pericentric inversion of the Y chromosome. A re-evaluation at 3 years of age suggested that he was also affected by Beckwith-Wiedemann syndrome (BWS). Karyotype was repeated and fluorescence in situ hybridisation (FISH) analysis revealed trisomy for 11p15.5-->11pter and a distal monosomy 18q (18q23-->qter). Parental cytogenetic studies showed that the father carried a balanced cryptic translocation between chromosomes 11p and 18q. Furthermore, the child had an extra X chromosome and a "de novo" structural abnormality of chromosome Y. Thus, his karyotype was 47,XX, inv (Y) (p11.2 q11.23), der(18) t (11;18) (p15.5;q23) pat. ish der(18) (D11S2071+, D18S1390-). Two markers on the X chromosome showed that the extra X of the child was paternally inherited. No deletions were observed on the structurally abnormal Y chromosome from any of the microsatellites studied. Clinical findings of patients with BWS due to partial trisomy 11p reveal that there is a distinct pattern of dysmorphic features associated with an increased incidence of mental retardation when comparing patients with normal chromosomes. This fact reinforces that FISH study have to be performed in all BWS patients, specially in those with mental retardation since small rearrangements cannot be detected by conventional cytogenetic techniques.

    Mitochondrial DNA (mtDNA) depletion syndromes (MDS) are severe autosomal recessive disorders associated with decreased mtDNA copy number in clinically affected tissues. The hepatocerebral form (mtDNA depletion in liver and brain) has been associated with mutations in the POLG, PEO1 (Twinkle), DGUOK and MPV17 genes, the latter encoding a mitochondrial inner membrane protein of unknown function. The aims of this study were to clarify further the clinical, biochemical, cellular and molecular genetic features associated with MDS due to MPV17 gene mutations. We identified 12 pathogenic mutations in the MPV17 gene, of which 11 are novel, in 17 patients from 12 families. All patients manifested liver disease. Poor feeding, hypoglycaemia, raised serum lactate, hypotonia and faltering growth were common presenting features. mtDNA depletion in liver was demonstrated in all seven cases where liver tissue was available. Mosaic mtDNA depletion was found in primary fibroblasts by PicoGreen staining. These results confirm that MPV17 mutations are an important cause of hepatocerebral mtDNA depletion syndrome, and provide the first demonstration of mosaic mtDNA depletion in human MPV17 mutant fibroblast cultures. We found that a severe clinical phenotype was associated with profound tissue-specific mtDNA depletion in liver, and, in some cases, mosaic mtDNA depletion in fibroblasts. PMID:23714749

    We report on a left-handed patient with an ischemic infarction affecting exclusively the total length of the corpus callosum. This lesion clinically correlated with an almost complete callosal disconnection syndrome as described in callosotomy subjects, including unilateral verbal anosmia, hemialexia, unilateral ideomotor apraxia, unilateral agraphia, unilateral tactile anomia, unilateral constructional apraxia, lack of somesthetic transfer and dissociative phenomena. Despite the patient's left-handedness, his pattern of deficits was similar to the disconnection syndrome found in right-handers. Our report focusses on motor dominance and praxis. We followed-up the improvement in left apraxia and investigated the ability to initiate and learn a new visuo-motor skill. The results permit two tentative assumptions: (1) that the improvement in left apraxia was due to a compensatory increase in ipsilateral proximal muscle control, and (2) that motor dominance, i.e. the competence to initiate and learn a new movement pattern, was hemispherically dissociable from manual dominance in the sense of praxis control.

    Full Text Available Abstract Background One of the rare presentations of superior vena cava syndrome is bleeding of "downhill" esophageal varices (DEV and different approaches have been used to control it. This is a case report whose DEV was eradicated by band ligation for the first time. Case presentation We report a 42-year-old man who is a known case of Behcet's disease. The patient's first presentation was superior vena cava syndrome due to thrombosis followed by bipolar ulcers and arthralgia. He received warfarin, prednisolone and azathioprine. The clinical course of the patient was complicated by one episode of hematemesis without abdominal pain when the patient's PT was in therapeutic range. After resuscitation and correction of PT with fresh frozen plasma transfusion, upper gastrointestinal endoscopy was done. Prominent varices were seen in the upper third of the esophagus, tapering to the middle part without acute bleeding. Stomach and duodenum were normal. Color ultrasonography evaluation of the portal, hepatic and splenic veins was negative for thrombosis. Band ligation was done and the patient's bleeding did not recur. Conclusion Band ligation is a safe and effective method for controlling DEV bleeding in patients with uncorrectable underlying disorders.

    Canal of Nuck abnormalities are a rare but important cause of morbidity in girls, most often those younger than 5 years of age. The canal of Nuck, which is the female equivalent of the male processus vaginalis, is a protrusion of parietal peritoneum that extends through the inguinal canal and terminates in the labia majora. The canal typically obliterates early in life, but in some cases the canal can partially or completely fail to close, potentially resulting in a hydrocele or hernia of pelvic contents. Recognition of this entity is especially important in cases of ovarian hernia due to the risk of incarceration and torsion. We aim to increase awareness of this condition by reviewing the embryology, anatomy and diagnosis of canal of Nuck disorders with imaging findings on US, CT and MRI using several cases from a single institution.

    Clinical, radiological, histological and immunohistochemical methods were used to define the nature of multiple rapidly growing hepatic nodules in 2 young patients with Budd-Chiari syndrome due to myeloproliferative diseases. In one patient, the arterial hyperperfusion of large nodules was demonstrated by dynamic computed tomography and angiography. The explanted livers of these patients showed multiple well-demarcated nodules up to 3 cm in diameter on the background of liver cirrhosis resulting from chronic hepatic congestion. Histologically, these nodules covered a spectrum ranging from adenoma-like lesions to nodules resembling focal nodular hyperplasia. They consisted of essentially normal hepatocytes, and variably contained fibrous septa including neoductules and large, mostly dysmorphic arteries. Sometimes, they were located close to still patent or recanalized veins. These rapidly growing hepatic nodules are best defined as macroregenerative nodules. The knowledge of this entity may help the physician to avoid misinterpretation of such nodules as carcinomas.

    Cellular homeostasis is maintained by the highly organized cooperation of intracellular trafficking systems, including COPI, COPII, and clathrin complexes. COPI is a coatomer protein complex responsible for intracellular protein transport between the endoplasmic reticulum and the Golgi apparatus. The importance of such intracellular transport mechanisms is underscored by the various disorders, including skeletal disorders such as cranio-lenticulo-sutural dysplasia and osteogenesis imperfect, caused by mutations in the COPII coatomer complex. In this article, we report a clinically recognizable craniofacial disorder characterized by facial dysmorphisms, severe micrognathia, rhizomelic shortening, microcephalic dwarfism, and mild developmental delay due to loss-of-function heterozygous mutations in ARCN1, which encodes the coatomer subunit delta of COPI. ARCN1 mutant cell lines were revealed to have endoplasmic reticulum stress, suggesting the involvement of ER stress response in the pathogenesis of this disorder. Given that ARCN1 deficiency causes defective type I collagen transport, reduction of collagen secretion represents the likely mechanism underlying the skeletal phenotype that characterizes this condition. Our findings demonstrate the importance of COPI-mediated transport in human development, including skeletogenesis and brain growth. Copyright © 2016 American Society of Human Genetics.

    Full Text Available Objective: Ishemic bone disease has multifactorial etiologies. Cronic dental infections should be eliminated to prevent osteonecrosis of the jaw. Case report: We report an unusual case of osteonecrosis due to the pulpal-peridontal syndrome and subsequent pulp necrosis. A case of 38 year old woman who presented with exposed bone, 8 mm in diameter, in the lingual area of the right lower third molar. The patient was otherwise healthy and was not taking any medications. A detailed medical history showed no previous diseases. Patient denied any type of local trauma. A complete blood count showed no abnormalities. The panoramic radiograph revealed a deep periodontal pocket between teeth 47 and 48. The CBCT revealed a deep periodontal pocket between molars and bone sequestrum of the lingual plate. Topical treatment consisted of adhesive periodontal dressing based on the cellulose and betamethasone oitnment together with orabase, without improvement. Therefore, peroral amoxycillin was prescribed for a week. Since there was no improvement, the third molar was removed as well as necrotic bone; the alveolar bone was remodelled and utures were placed. After suturing, the whole area was covered using intraoral resorbable bandage. Microbial swab of the wound aspirate did not reveal polymorphonuclears or the presence of icroorganisms. Microbial swab of the biopsy specimen of the necrotic bone particle and sequestrum showed a large amount of gram-positive coccae, however, polymorphonuclears were not found. Histopathological analysis revealed acute chronic inflammation. One week after the surgery, the area healed completely. Conclusion: This case highlights the fact that in some patients bone exposure might develop due to the pulpal-peridontal syndrome i.e. pulp necrosis.

    2008-01-01

    Full Text Available INTRODUCTION Taurodontism is a morphoanatomical change in the shape of a tooth. An enlarged body of a tooth with smaller than usual roots is a characteristic feature. Internal tooth anatomy correlates with this appearance, which means that a taurodontal tooth has a large pulp chamber and apically positioned furcations. This dental anomaly may be associated with different syndromes and congenital discoders. CASE OUTLINE The case report presents the patient of a rare case of taurodontism in the mandibular second premolar with chronic periodontitis. Endodontic treatment was performed after dental history and clinical examination. Special care is required in all segments of endodontic treatment of a taurodontal tooth from the identification orifice, canal exploration, determining working length, cleaning and shaping and obturation of the root canal. Precurved K-file was used for canal exploration and location of the furcation. One mesial and one distal canal with the buccal position were identified in the apical third of the root canal. The working lengths of two canals were determined by radiographic interpretation with two K-files in each canal and verified with the apex locator. During canal instrumentation, the third canal was located in the disto-lingual position. The working length of the third canal was established using the apex locator. CONCLUSION Thorough knowledge of tooth anatomy and its variations can lead to lower percentage of endodontic failure. Each clinical case involving these teeth should be investigated carefully, clinically and radiographically to detect additional root canals. High quality radiographs from different angles and proper instrumentarium improve the quality of endodontic procedure.

    Angelman syndrome (AS) is characterised by developmental delay, lack of speech, seizures, a characteristic behavioural profile with a happy demeanour, microcephaly, and ataxia. More than two-thirds of cases are due to an approximately 5-Mb interstitial deletion of the imprinted region 15q11.2q13, which is usually de novo. The rest are associated with point mutations in the UBE3A gene, imprinting defects, and paternal uniparental disomy. Small intragenic UBE3A deletions have rarely been described. They are usually maternally inherited, increasing the recurrence risk to 50%, and may be missed by conventional testing (methylation studies and UBE3A gene sequencing). We describe a boy with AS due to an 11.7-kb intragenic deletion. The deletion was identified by array-CGH and was subsequently detected in his affected first cousin and unaffected maternal grandfather, mother, and aunt, confirming the silencing of the paternal allele. The patient had developmental delay, speech impairment, a happy demeanour, microcephaly, and an abnormal EEG, but no seizures by the age of 4 years. Delineation of the underlying genetic mechanism is of utmost importance for reasons of genetic counselling, as well as appropriate management and prognosis. Alternative techniques, such as array-CGH and MLPA, are necessary when conventional testing for AS has failed to identify the underlying genetic mechanism. © 2017 S. Karger AG, Basel.

    Our objective was to evaluate efficacy and patency of metallic stent placement for symptomatic Budd-Chiari syndrome (BCS) due to prothrombotic disorders. Eleven patients with proved BCS due to prothrombotic disorders were referred for endovascular treatment because of refractory ascites (n=9), abdominal pain (n=8), jaundice (n=6), and/or gastrointestinal bleeding (n=4). Stents were inserted for stenosed hepatic vein (n=7), inferior vena cava (n=2), or mesenterico-caval shunt (n=2). Clinical efficacy and stent patency was evaluated by clinical and Doppler follow-up. After a mean follow-up of 21 months, 6 patients had fully patent stents without reintervention (primary stent patency: 55%). Two patients with hepatic vein stenosis had stent thrombosis and died 4 months after procedure. Restenosis occurred in 3 cases (2 hepatic vein and 1 mesenterico-caval shunt stenosis) and were successfully treated by balloon angioplasty (n=2) and addition of new stents (n=1) leading to a 82% secondary stent patency. Of 9 patients with patent stent, 7 were asymptomatic (77%) at the end of the study. Stent placement is a safe and effective procedure to control of symptomatic BCS. Prothrombotic disorder does not seem to jeopardize patency in anticoagulated patients. (orig.)

    To determine the effects of acetylsalicylic acid (ASA) and acetaminophen on mortality due to influenza B infection in neonatal and weanling mice, as well as any synergistic, antagonistic or indifferent effects of the combined antipyretic and virus on mortality in mice pretreated with low doses of an industrial surfactant, Toximul MP8, which has been shown to reproduce many of the features of Reye's syndrome. In vitro studies were done to determine whether ASA or acetaminophen altered the normal, interferon-mediated antiviral responses of mammalian cells. The involvement of ASA or other commonly used xenobiotics in the induction of Reye's syndrome following virus illness has not been resolved; to do so, and to elucidate the underlying metabolic mechanism, requires these studies in an animal model. Prospective animal study. Newborn (945) and weanling (840) Swiss white mice, divided into 12 subgroups. Some groups received Toximul MP8 before inoculation with a dose of mouse-adapted human influenza B that produces 30% mortality (LD30); after infection, each subgroup received either placebo, ASA or acetaminophen. Mortality counts were taken daily. The in vitro effects of the antipyretics on interferon response were determined using standard virology techniques. Mortality, analyzed by survival curves (log rank test) or cumulative daily mortality (chi 2 analysis). Plaque-reducing dose (PRD50) was used to determine the outcome of the in vitro analyses. In neonatal mice, only subgroups given combined treatment with acetaminophen and Toximul MP8 had a statistically significant higher mortality rate than with the mice given influenza B alone. In weanling mice, it appeared that ASA shortened the time until death; however, this difference was not statistically significant. In vitro studies demonstrated that both ASA and acetaminophen decreased the interferon-induced antiviral responses of cultured mammalian cells. Antipyretics have the potential to exacerbate the consequences of

    Iatrogenic Cushing's syndrome (CS) is caused by exposure to glucocorticoids and may be promoted by interaction with additional drugs. It is well known in asthmatic human immunodeficiency virus (HIV)-infected patients treated with inhaled fluticasone with ritonavir-containing antiretroviral regimen (cART). The authors present an asthmatic HIV-infected Ethiopian woman, treated with fluticasone/salmeterol, commencing cART with tenofovir, emtricitabine, and lopinavir/ritonavir. During 7 months she gained 9 kg and hyperpigmentation, mild edema, marked abdominal striae, and increase in blood pressure were noted. Plasma am and urine free cortisol levels confirmed CS diagnosis and fluticasone was discontinued. Complete resolution of CS occurred within 2 months. However, frequent asthma symptoms required resumption of inhaled corticosteroid (ICS) treatment, and budesonide/formeterol was prescribed. Soon reemergence of symptomatic CS was noted. Ritonavir dose was halved, but CS symptoms continued to develop. Budesonide was stopped and montelukast initiated. Resolution of cushingoid symptoms was observed within weeks. Corticosteroids are metabolized by cytochrome P450 3A4 (CYP3A4). Fluticasone has the longest glucocorticoid receptor-binding half-life and is 300 times more lipophilic than budesonide. Inhaled fluticasone possesses a high suppression rate of hypothalamic-pituitary-adrenal axis. Ritonavir, a potent CYP3A4 inhibitor, may inhibit corticosteroid degradation and increase its accumulation. Inhaled budesonide is less likely to cause adrenal suppression. Diagnosing Cushing's syndrome presents a clinical challenge due to similarities with clinical manifestations and side effects related to cART. In patients treated with inhaled or intranasal corticosteroids together with cART there may be a higher incidence of iatrogenic CS. CS should be looked for, and management considered carefully.

    5p deletion syndrome or Cri du Chat syndrome is a autosomal deletion syndrome, caused by the de novo deletion of chromosome 5p in the majority of the cases. Clinical features include developmental delay, microcephaly, subtle facial dysmorphism and high-pitched cry. With the advent of newer techniques such as multiplex ligation-dependent probe amplification, rapid diagnosis is possible and chromosomal microarray helps in accurate delineation of the breakpoints. In this study, we characterized probands from two Indian families who had duplication of another chromosome in addition to deletion of 5p region. In the first family, two females of 3 and 5 yr of age had deletion of 5p15.33p15.2 (14.7 Mb) and duplication of 8q24.21q24.3 (15.4 Mb). Proband in the second family was a 2-year-old female and had deletion of 5p15.33p14.3 (22.55 Mb) along with duplication of 12p13.33p13.31 (7.7 Mb). In both the families, father was balanced translocation carrier of the chromosomes involved. Patients in family 1 had overwhelming features of 5p deletion while patient in family 2, besides having features of 5p deletion, showed many features of 12p duplications. Prenatal diagnosis was possible in both the families. To the best of our knowledge, this is the first detailed molecular cytogenetic analysis and prenatal diagnosis report of 5p deletion syndrome from India.

    Full Text Available Cushing’s syndrome (CS due to ectopic adrenocorticotrophic hormone (ACTH is associated with a variety of tumours most of which arise in the thorax or abdomen. Prostate carcinoma is a rare but important cause of rapidly progressive CS. To report a case of severe CS due to ACTH production from prostate neuroendocrine carcinoma and summarise previous published cases. A 71-year-old male presented with profound hypokalaemia, oedema and new onset hypertension. The patient reported two weeks of weight gain, muscle weakness, labile mood and insomnia. CS due to ectopic ACTH production was confirmed with failure to suppress cortisol levels following low- and high-dose dexamethasone suppression tests in the presence of a markedly elevated ACTH and a normal pituitary MRI. Computed tomography demonstrated an enlarged prostate with features of malignancy, confirmed by MRI. Subsequent prostatic biopsy confirmed neuroendocrine carcinoma of small cell type and conventional adenocarcinoma of the prostate. Adrenal steroidogenesis blockade was commenced using ketoconazole and metyrapone. Complete biochemical control of CS and evidence of disease regression on imaging occurred after four cycles of chemotherapy with carboplatin and etoposide. By the sixth cycle, the patient demonstrated radiological progression followed by recurrence of CS and died nine months after initial presentation. Prostate neuroendocrine carcinoma is a rare cause of CS that can be rapidly fatal, and early aggressive treatment of the CS is important. In CS where the cause of EAS is unable to be identified, a pelvic source should be considered and imaging of the pelvis carefully reviewed.

    2012-07-01

    A 48-year-old woman with HIV infection developed Cushingoid features while she was taking ritonavir-boosted darunavir. Cushing's syndrome was confirmed due to the drug interaction between ritonavir and budesonide. Diagnosis of iatrogenic Cushing's syndrome in HIV-positive patients who are on ritonavir-boosted protease inhibitors (PIs) presents a clinical challenge due to similar clinical features of lipohypertrophy related to ritonavir-boosted PIs. Although this complication has been widely described with the use of inhaled fluticasone, the interaction with inhaled budesonide at therapeutic dose is not widely recognized.

  13. Traumatic brain injury is unlikely precipitating Leigh syndrome due to the GJB2 mutation c.35delG

    2017-06-01

    Full Text Available With interest we read the article by Ashrafi et al. about a 14-year-old female who is regarded to have developed Leigh syndrome (LS after traumatic brain injury (TBI. We have the following comments and concerns:We do not agree with the notion that traumatic brain injury was the precipitating factor for LS. The patient had a history of hypoacusis, which is a typical clinical manifestation of a mitochondrial disorder (MID. Hypoacusis obviously had developed long before the TBI. Additionally, the patient was diagnosed with neuropathy of the peripheral nerves two months after TBI. It is rather unlikely that neuropathy was triggered by TBI and more likely it was already present before the trauma. Thus, the initial manifestations of LS in the presented patient were most likely hypoacusis followed by neuropathy and TBI only might have triggered the seizure but not the MID. Why was the patient put on phenytoin, which is well-known to be mitochondrion-toxic? Phenytoin may worsen epilepsy and MID in general and it is conceivable that in fact phenytoin was responsible for worsening of the phenotype and not the TBI. In a 16-year-old female with MELAS syndrome due to the mutation m.3243A>G, phenytoin caused intestinal pseudo-obstruction one month after intravenous phenytoin for status epilepticus. In a patient with Kearns-Sayre syndrome phenytoin decreased cerebrospinal fluid (CSF folate levels. In rat hepatocytes, phenytoin increased reactive oxygen species (ROS formation, decreased intracellular reduced glutathione, increased intracellular oxidised glutathione, and enhanced lipid peroxidation and mitochondrial damage. In a hepatic microsomal system, phenytoin decreased state-3 respiration, ATP synthesis, and the mitochondrial membrane potential. In this model, phenytoin increased state-4 respiration, impaired Ca++-uptake and release, and inhibited Ca++-induced swelling. It would be interesting to know how the GJB2 mutation was detected.

    Full Text Available Cannabinoid Hyperemesis Syndrome (CHS was first described in 2004. Due to its novelty, CHS is often unrecognized by clinicians leading to expensive workup of these patients with cyclical symptoms. It may take up to 9 years to diagnose CHS. CHS is characterized by cyclical nausea and vomiting, abdominal pain, and an unusual compulsion to take hot showers in the presence of chronic use of cannabinoids. Cannabicyclohexanol is a synthetic cannabinoid, popularly known as K2 spice. It is a popular marijuana alternative among teenagers and young adults since it is readily available as herbal incense.

    Full Text Available A 37-year-old Caucasian woman presented with acute decrease in central vision in her right eye and was found to have subfoveal choroidal neovascularization (CNV due to presumed ocular histoplasmosis syndrome (POHS. Her visual acuity improved from 20/70 to 20/20 at her 6-month follow-up, after 3 consecutive monthly intravitreal bevacizumab injections were initiated at her first visit. Although no CNV activity was seen on fluorescein angiography (FA or spectral-domain optical coherence tomography (SD-OCT at her 2-month, 4-month, and 6-month follow-up visits, persistent flow in the CNV lesion was detected on optical coherence tomography angiography (OCTA. OCTA shows persistent vascular flow as well as changes in vascular flow in CNV lesions associated with POHS, indicating the continued presence of patent vessels and changes in these CNV lesions, even when traditional imaging of the lesion with OCT and FA indicates stability of the lesion with no disease activity. Additional cases with longitudinal follow-up are needed to assess how OCTA should be incorporated into clinical practice.

    Visual hallucinations are a common and often distressing consequence of vision loss, particularly in age-related macular degeneration. Charles Bonnet Syndrome (CBS) is defined by the triad of complex visual hallucinations, ocular pathology causing visual deterioration and preserved cognitive status. So far, although this condition is frequent, no established treatment for CBS has been stated. We report here the case of a 78-year-old woman, who came in our hospital because of a 4-week long mild depressive symptomatology. For 1 year she experienced daily sudden, unexpected, vivid and elaborate hallucinations. Insight was completely present, so the patient stated that the hallucinations were unreal and that the faces, geometrical figures and animals she saw every day were possibly due to her vision loss. The Mini Mental State Examination, digit span and verbal fluency were administered and no cognitive impairment was reported. The visual acuity was hand motion. After 4 days of treatment with venlafaxine the hallucinations completely disappeared. This is the first case to show that selective serotonin (and noradrenalin) reuptake inhibitors may be an effective and well-tolerated treatment for visual hallucinations associated with vision loss, and it adds to evidence implicating serotonergic pathways in the pathogenesis of visual hallucinations.

    2004-02-01

    The metabolic syndrome (MS) is associated with cardiovascular disease. The low high-density lipoprotein cholesterol (HDL-C) seen in the MS is associated with increased hepatic secretion of apolipoprotein B-containing lipoproteins. Patients with low HDL-C and abnormal cellular lipid efflux due to ABCA1 gene defects (Tangier disease) also have elevated plasma triglycerides. In the present study, we examined the cellular cholesterol and phospholipid efflux in patients with low HDL-C and features of the MS. Forty-four patients with a HDL-C below the fifth percentile for age and gender were selected. The MS was defined by a low HDL-C and at least two additional features: body mass index at least 30 kg/m(2), plasma triglycerides at least 150 mg/dl, fasting glucose at least 110 mg/dl, and blood pressure at least 130/85 mm Hg. Cellular lipid efflux was examined on fibroblasts obtained from study subjects, nine normal controls and six subjects with Tangier disease. In 22 patients identified with the MS, HDL-C was 21 +/- 7 mg/dl, triglyceride levels were 340 +/- 157 mg/dl, and cellular cholesterol and phospholipid efflux were 107 +/- 18% and 105 +/- 17% of controls, respectively. No patient with the MS and low HDL-C showed a cellular lipid efflux defect. We conclude that primary cellular lipid efflux defects do not contribute to the low HDL-C frequently encountered in the MS.

    Full Text Available Background: In India, hydrogen cyanamide (Dormex ® is a plant growth regulator used mainly for the bud-breaking of grapevines. The use of this chemical may result in severe cutaneous reactions simulating erythema multiforme (EM, Stevens-Johnson syndrome (SJS and toxic epidermal necrolysis (TEN. Methods: Studies were conducted on four seasonal grapevine workers who developed severe cutaneous reactions following the unprotected use of Dormex ® (hydrogen cyanamide. Results: Two of the patients had EM-like skin lesions and the other two developed SJS-TEN-like skin lesions. A latent period of 5-7 days existed between the contact with the chemical and the development of the skin lesions. The histopathological picture was suggestive of EM. All the patients responded to systemic steroids and antihistamines. Conclusions: Hydrogen cyanamide may act as a hapten, initiating cytotoxic immunological attack on keratinocytes, resulting in EM- and SJS-TEN-like clinical picture. Awareness regarding such severe cutaneous reactions due to the inappropriate handling of Dormex ® is required. The use of personal protection equipments while handling agricultural chemicals is essential.

    A 79-year-old man with a 3-month history of lymphedema of the lower limbs, and diabetes mellitus, was admitted to our hospital for suspected deep venous thrombosis. Several hours after admission, leg pain and purpura-like skin color appeared. On the 2nd hospital day, he was referred to our department for possible acute occlusive peripheral artery disease (PAD) and skin necrosis with blisters; however, computed tomography with contrast showed no occlusive lesions. He had already developed shock and necrotizing deep soft-tissue infections of the left lower leg. Laboratory findings revealed renal dysfunction and coagulation system collapse. Soon after PAD was ruled out, clinical findings suggested necrotizing deep soft-tissue infections, shock state, disseminated intravascular coagulation, and multiple organ failure. These symptoms led to a high suspicion of the well-recognized streptococcal toxic shock syndrome (STSS). With a high suspicion of STSS, we detected Group G β-hemolytic streptococci (GGS) from samples aspirated from the leg bullae, and the species was identified as Streptococcus dysgalactiae subsp. equisimilis (SDSE) by 16S-ribosomal RNA sequencing. However, unfortunately, surgical debridement was impossible due to the broad area of skin change. Despite adequate antimicrobial therapy and intensive care, the patient died on the 3rd hospital day. The M-protein gene (emm) typing of the isolated SDSE was revealed to be stG6792. This type of SDSE is the most frequent cause of STSS due to GGS in Japan. We consider it to be crucial to rapidly distinguish STSS from acute occlusive PAD to achieve life-saving interventions in patients with severe soft-tissue infections.

    We report here a study on efficacy of sevelamer hydrochloride in treating hyperphosphatemia due to tumor lysis syndrome (TLS) in a developing world setting. Twenty one children with hyperphosphatemia due to TLS were included. All received hyper-hydration, allopurinol and sevelamer. Efficacy was assessed by decrease in serum phosphate level, calcium-phosphate product and TLS score as per Cairo Bishop definition. Four children who underwent dialysis were excluded from analysis. Among the remaining 17 patients with hyperphosphatemia, laboratory TLS was recorded in 15 patients and clinical TLS in five. Sevelamer was given according to weight, most often 400 mg twice to thrice daily. Mean phosphatemia decreased from 8.3 ± 3.0 to 6.7 ± 2.1 mg/dl within 24 h of starting sevelamer (p = 0.02), 6.0 ± 2.1 mg/dl at 48 h, 4.9 ± 1.5 mg/dl at 72 h and 4.39 ± 1.7 mg/dl at 96 h. TLS was corrected in 72 h in 14 patients, 96 h in 1 and 120 h in another patient. Mean calcium-phosphate product decreased from 63.0 ± 14.0 to 49.2 ± 9.7 mg/dl (p = 0.002) at 24 h, 46.1 ± 17.0 mg/dl at 48 h and 39.7 ± 13.5 mg/dl at 72 h. There was no mortality due to hyperphosphatemia. Sevelamer is efficacious in children with malignancy-associated hyperphosphatemia in the developing world.

  8. MANAGEMENT OF LUMBAR SPINAL CANAL STENOSIS

    Directory of Open Access Journals (Sweden)

    Mukhergee G. S

    2016-06-01

    Full Text Available BACKGROUND Spinal stenosis is one of the most common conditions in the elderly. It is defined as a narrowing of the spinal canal. The term stenosis is derived from the Greek word for narrow, which is “Stenos”. The first description of this condition is attributed to Antoine portal in 1803. Verbiest is credited with coining the term spinal stenosis and the associated narrowing of the spinal canal as its potential cause. [1-10] Kirkaldy–Willis subsequently described the degenerative cascade in the lumbar spine as the cause for the altered anatomy and pathophysiology in spinal stenosis. [11-15] If compression does not occur, the canal should be described as narrow but not stenotic. Some studies defined lumbar spinal stenosis as a “narrowing of the osteoligamentous vertebral canal and/or the intervertebral foramina causing compression of the thecal sac and/or the caudal nerve roots; at a single vertebral level, narrowing may affect the whole canal or part of it” (Postacchini 1983. This definition distinguished between disc herniation and stenosis. [16] . The most common type of spinal stenosis is caused by degenerative arthritis of the spine. Hypertrophy and ossification of the posterior longitudinal ligament which usually are confined to the cervical spine, and diffuse idiopathic skeletal hyperostosis (DISH syndrome also may result in an acquired form of spinal stenosis. Congenital forms caused by disorders such as achondroplasia and dysplastic spondylolisthesis are much less common. Congenital spinal stenosis usually is central and is evident or imaging studies. Idiopathic congenital narrowing usually involves the anteroposterior dimension of the canal secondary to short pedicles; the patient otherwise is normal. In contrast, in achondroplasia, the canal is narrowed in the anteroposterior plane owing to shortened pedicles and in lateral dimension because of diminished interpedicular distance. Acquired forms of spinal stenosis usually are

    Allogeneic natural killer (NK) cell products for treatment of solid organ malignancies were prepared by performing T (CD3+)-cell depletion on nonmobilized apheresis mononuclear cell collections. The products were not B-cell depleted. This report details two cases of passenger lymphocyte syndrome (PLS) after NK-cell infusion. Patient 1 is a blood group A+ 56-year-old female with Stage IV ovarian carcinoma who received NK cells from an O+ donor. On day +7 she developed new hemolytic anemia. Direct antiglobulin test (DAT) was positive for immunoglobulin G and C3, and the eluate contained anti-A. Subsequently, anti-A was identified on reverse typing. She was transfused with group O red blood cells (RBCs). By day +12 she forward typed as O with anti-A and B on reverse typing. By day +42, DAT was negative with only weak anti-A on reverse typing. Patient 2 is a blood group B+ 51-year-old female with metastatic lobular breast carcinoma who received NK cells from an O+ donor. On day +7 she developed new hemolytic anemia. DAT was positive, and the eluate contained anti-A and -B. Anti-A reactivity was due to anti-A,B. The next day she developed new anti-B on reverse typing. She was transfused with O RBCs. Anti-B titer increased to a maximum of 512 on day +12. At discharge on Day +29 her anti-B titer was still 32. These patients developed PLS after infusion of NK cells. Because of these cases NK-cell products are now B (CD19+)-cell depleted at our institution, and this approach is recommended for other centers. © 2012 American Association of Blood Banks.

    Bilateral adrenalectomy is currently the only available treatment for adrenocorticotropic hormone (ACTH)-dependent Cushing’s syndrome (ectopic ACTH syndrome) that is refractory to pharmacologic therapy. We describe two patients with refractory ectopic ACTH syndrome who were treated with CT-guided percutaneous microwave ablation of both hyperplastic adrenal glands in a single session: One was not a surgical candidate, and the other had undergone unsuccessful surgery. Following the procedure, both patients achieved substantial decreases in serum cortisol, symptomatic improvement, and decreased anti-hypertensive medication requirements.

    Bovine papillomavirus type 4 (BPV-4) is the aetiological agent of epithelial papillomas of the upper alimentary canal in cattle. These benign tumours can become a focus for transformation to squamous cell carcinomas in animals feeding on bracken fern. Strong epidemiological evidence suggests that the progression to malignancy is due to the interplay between BPV-4 and mutagenic and immunosuppressing chemicals present in the fern. The carcinomas of the upper alimentary canal are often accompanied by adenomas and adenocarcinomas of the lower intestine and bracken-grazing animals are also heavily immunosuppressed. To elucidate the individual roles and the concerted action of the viral and chemical factors involved in tumorigenesis and malignant conversion, we attempted to reproduce experimentally the cancer syndrome observed in the field. Florid persistent papillomatosis of the upper alimentary canal was reproduced in animals infected with BPV-4 and immunosuppressed either by a diet of bracken or by treatment with azathioprine; cancer of the upper alimentary tract or of the lower intestine developed only in animals infected with virus and fed on bracken fern. As in field cases, BPV-4 DNA was detected in papillomas but not in cancers. We conclude that immunosuppression is necessary for persistence and spread of viral papillomas, that the fern mutagens are responsible for neoplastic conversion of papilloma cells, and that continuous expression of viral functions is not required for the maintenance of the malignant state.

  12. Hyponatremia in aneurysmal subarachnoid hemorrhage is due to the syndrome of inappropriate antidiuresis and acute glucocorticoid deficiency

    Hannon, M J

    2011-06-01

    Hyponatraemia is the most common electrolyte abnormality following subarachnoid haemorrhage (SAH) and contributes to increased morbidity and mortality. Retrospective data suggests that the syndrome of inappropriate diuresis (SIAD) is the most common cause of hyponatraemia in SAH, though cerebral salt wasting has been postulated by some workers to be the predominant abnormality. Data which has shown acute glucocorticoid deficiency following SAH has suggested that some cases of euvolaemic hyponatraemia may also be caused by this mechanism.We prospectively studied the hormonal and haemodynamic influences involved in the development of hyponatraemia in 100 patients (61% female, median age 53 (range 16-82)) with non-traumatic aneurysmal SAH. Each patient had plasma sodium (pNa), urea, osmolality, glucose and 0900h cortisol (PC), and urinary sodium and osmolality measured on days 1, 2, 3, 4, 6, 8, 10 and 12 following SAH. Fluid balance and haemodynamic parameters were recorded daily. Results were compared with 15 patients admitted to ITU following vascular surgery. A PC<300nmol\\/L in a patient in ITU was regarded clinically as inappropriately low.49% of patients developed hyponatraemia (pNa<135 mmol\\/L), including 14% who developed clinically significantly hyponatraemia (pNa<130 mmol\\/L). 36\\/49 (73.4%) developed hyponatraemia between days 1 and 3 post SAH. The median duration of hyponatraemia was 3 days (range 1–10 days).In 35\\/49 (71.4%), hyponatraemia was due to SIAD as defined by standard diagnostic criteria. 14% of SAH patients had at least one PC<300nmol\\/L; 5 of these (35.7%) developed hyponatraemia. In 4 patients hyponatraemia was preceded by acute cortisol deficiency and responded to hydrocortisone treatment. In contrast, all controls had PC>500 nmol\\/L on day 1, and >300 nmol on days 3–12. There were no cases of cerebral salt wasting. There was no relationship between the incidence of hyponatraemia and the defined anatomical territory or severity of

    Pure dysarthria (PD) and dysarthria-facial paresis syndrome (DFP) mainly result from lenticulostriate artery territory infarction. PD and DFP are rare clinical entities, often grouped without distinction. The purpose of this study was to examine clinical and radiographic differences between PD and DFP due to unilateral internal capsule and/or corona radiata infarction. Using a database that included consecutive patients with ischemic stroke admitted to the neurological stroke units of three hospitals within 7 days from onset between September 2011 and April 2014, we retrospectively extracted first-ever stroke patient data, who presented with PD or DFP with a single ischemic lesion localized in the internal capsule and/or corona radiata. Patients with weakness, ataxia, sensory deficit, or cortical symptoms were excluded. Ischemic lesion volume was calculated by the ABC/2 method on diffusion-weighted imaging (DWI). DWI images were normalized and superimposed to the template for PD and DFP. We compared patients' characteristics between PD and DFP. A total of 2126 patients, including 65 patients (3.1%) with PD or DFP, were registered. Of these, 13 PD patients and 18 patients with DFP due to unilateral internal capsule and/or corona radiata infarction were included for analysis. Compared with DFP patients, PD patients had longer onset-to-door time (median 37.5 vs. 10.8 h, p = 0.031), shorter vertical length (C component) of ischemic lesions (median 12.0 vs. 18.8 mm, p = 0.007), and smaller ischemic lesion volume (median 285 vs. 828 mm(3), p = 0.023). Ischemic lesions causing PD were located more frequently in the left hemisphere than DFP (92% vs. 56%, p = 0.045). The superimposed lesion pattern indicated that DFP had lesions more medial and involving posterior portions of the putamen and the caudate body, as well as more of the genu and posterior limb of the internal capsule, than PD. Ninety days after onset, symptoms disappeared in 21 (72%) out of 29 patients. In

    Full Text Available Dilaceration is the result of a developmental anomaly in which there has been an abrupt change in the axial inclination between the crown and the root of a tooth. Dilaceration can be seen in both the permanent and deciduous dentitions, and is more commonly found in posterior teeth and in maxilla. Periapical radiographs are the most appropriate way to diagnose the presence of root dilacerations. The controlled regularly tapered preparation of the curved canals is the ultimate challenge in endodontics. Careful and meticulous technique will yield a safe and sufficient enlargement of the curved canals. This article gives a review of the literature and three interesting case reports of root dilacerations.

    The case is presented of a 25-year-old Caucasian patient with Budd-Chiari syndrome due to membranous obstruction of the liver veins and inferior caval vein syndrome as a result of secondary hyperplasia of the caudate lobe of the liver, obstructing the caval vein. Diagnosis was established...... by intravascular pressure measurements, ultrasound examinations and caval and liver vein angiograms. Treatment consisting of stent placement in the outlet of a hepatic vein and subsequent transjugular intrahepatic porto-systemic shunt (TIPS) insertion via the caval vein was successful. After 34 months of follow......-up the stents remain open and the patient is symptom free. This successful combination of stent placement and TIPS has not been described before. The case report is followed by a review of the literature on the use of angioplasty in short hepatic vein stenosis and TIPS in Budd-Chiari syndrome. It is concluded...

    Store-operated Ca(2+) entry is the major route of replenishment of intracellular Ca(2+) in animal cells in response to the depletion of Ca(2+) stores in the endoplasmic reticulum. It is primarily mediated by the Ca(2+)-selective release-activated Ca(2+) (CRAC) channel, which consists of the pore-forming subunits ORAI1-3 and the Ca(2+) sensors, STIM1 and STIM2. Recessive loss-of-function mutations in STIM1 or ORAI1 result in immune deficiency and nonprogressive myopathy. Heterozygous gain-of-function mutations in STIM1 cause non-syndromic myopathies as well as syndromic forms of miosis and myopathy with tubular aggregates and Stormorken syndrome; some of these syndromic forms are associated with thrombocytopenia. Increased concentration of Ca(2+) as a result of store-operated Ca(2+) entry is essential for platelet activation. The York Platelet syndrome (YPS) is characterized by thrombocytopenia, striking ultrastructural platelet abnormalities including giant electron-opaque organelles and massive, multilayered target bodies and deficiency of platelet Ca(2+) storage in delta granules. We present clinical and molecular findings in 7 YPS patients from 4 families, demonstrating that YPS patients have a chronic myopathy associated with rimmed vacuoles and heterozygous gain-of-function STIM1 mutations. These findings expand the phenotypic spectrum of STIM1-related human disorders and define the molecular basis of YPS. Published by Elsevier Inc.

    Mauriac syndrome is characterized by growth impairment, Cushingoid features, and hepatomegaly in patients with poorly controlled type 1 diabetes mellitus (T1DM). We report a novel presentation of Mauriac syndrome in a 9-year-old girl who was diagnosed with neonatal diabetes at 3 months of age due to the p.R201C mutation in KCNJ11. She was initially treated successfully with glipizide at a dose of 0.85 mg/kg/day but after being lost to follow-up and having improper adjustment in dose over many years, the recent dose of 0.6 mg/kg/day appears to have been insufficient for glycemic control but enough to maintain a low level of C-peptide and prevent diabetic ketoacidosis. With proper insulin administration, all presenting clinical characteristics were resolved within 1 month. A review of the literature relating to clinical manifestations of Mauriac syndrome in children with diabetes was performed and included in this report for comparison with our patient. While Mauriac syndrome has been traditionally associated with T1DM, the presence of Mauriac syndrome should not be excluded in other types of diabetes mellitus.

    Jacobsen syndrome (JBS) is an uncommon contiguous gene syndrome. About 85-92% of cases have a de novo origin. Clinical variability and severity probably depend on the size of the affected region. The typical clinical features in JBS include intellectual disability, growth retardation, craniofacial dysmorphism as well as craniosynostosis, congenital heart disease, and platelet abnormalities. The proband was a 1 year/3-month-old Mexican male. Oligonucleotide-SNP array analysis using the GeneChip Human Cytoscan HD was carried out for the patient from genomic DNA. The SNP array showed a 14.2-Mb deletion in chromosome 11q23.3q25 (120,706-134,938 Mb), which involved 163 RefSeq genes in the database of genomic variation. We report a novel deletion in JBS that increases the knowledge of the variability in the mutation sites in this region and expands the spectrum of molecular and clinical defects in this syndrome.

    Full Text Available Introduction. Turner syndrome presents with one of the most frequent chromosomal aberrations in female, typically presented with growth retardation, ovarian insufficiency, facial dysmorphism, and numerous other somatic stigmata. Gigantism is an extremely rare condition resulting from an excessive growth hormone (GH secretion that occurs during childhood before the fusion of epiphyseal growth plates. The major clinical feature of gigantism is growth acceleration, although these patients also suffer from hypogonadism and soft tissue hypertrophy. Case report. We presented a girl with mosaic Turner syndrome, delayed puberty and normal linear growth for the sex and age, due to the simultaneous GH hypersecretion by pituitary tumor. In the presented case all the typical phenotypic stigmata related to Turner syndrome were missing. Due to excessive pituitary GH secretion during the period while the epiphyseal growth plates of the long bones are still open, characteristic stagnation in longitudinal growth has not been demonstrated. The patient presented with delayed puberty and primary amenorrhea along with a sudden appearance of clinical signs of hypersomatotropinism, which were the reasons for seeking medical help at the age of 16. Conclusion. Physical examination of children presenting with delayed puberty but without growth arrest must include an overall hormonal and genetic testing even in the cases when typical clinical presentations of genetic disorder are absent. To the best of our knowledge, this is the first reported case of simultaneous presence of Turner syndrome and gigantism in the literature.

    Malignant tumours in the apices of the lungs, especially bronchogenic carcinoma (Pancoast tumours), are the most common cause of Pancoast' syndrome which presents with shoulder or arm pain radiating along the medial aspect of forearm and weakness of small muscles of hand with wasting of hypothenar eminence due to neoplastic involvement of C8 and T1 and T2 nerve roots of brachial plexus. There are a number of benign conditions which may lead to Pancoast's syndrome; fungal abscess located in the apex of lung is one of them. Oral or intravenous antifungals are the treatment of choice in this case and complete recovery is usual, whereas, surgical resection followed by chemoradiotherapy is the treatment of choice in case of Pancoast's syndrome due to lung cancers. Hence, tissue diagnosis is mandatory. Here, we report a case of apical fungal abscess causing Pancoast's syndrome in an immunocompetent individual of 35 years of age to raise the awareness among the clinicians regarding this rare clinical entity.

    Love Canal is known worldwide as the site of one of the worst non-nuclear environmental disasters in modern history. For 12 years, a Niagara Falls, New York chemical company used the canal bed as a chemical dump. This article discusses the computerized control of equipment used to remove the toxic materials from the ground under Love Canal, and how the minimization of maintenance is reducing maintenance costs and increasing operator safety.

  6. Analysis of sedimentation of canals

    Full Text Available The dredged canals in the Niger Delta coastal flood plain are being threatened by siltation. This study is limited to those canals in Rivers State of Nigeria, which are under the influence of tidal waves. A total of eight canals were considered with four each from Ekulama and Cawthorne Channel. Different approaches were used to carry out this study, which includes field reconnaissance survey, hydrographic survey, soil sample analysis and collection of all available data and information. The typical bed materials size (D50 is approximately 0.01mm; which gives a settling velocity of 0.09mm/sec using stroke’s law. Hydrographic survey of the canals from 1992 to 1996 revealed an average siltation rate of 2.35m/yr. A regression equation was also derived which relates the cost of dredging to canal area, rate of siltation and average aggregation. A plot of canal centre profile; entrance, middle and end cross sections showing sediment distribution along the canal profile, shows that majority of the particles that form the sediment enter the canal from the rivers. The sedimentation is caused by the reduction in water current, which has average value of 0.0145m/sec. The bathyorographical check on the canals revealed that the sum of the two exterior angles of the canal with the river at the point of connection has to lie within 1800 + 50 for an effective flow that will minimize settlement of particles. In addition, the canals should be constructed to start and terminate on a moving water body, to avoid dead ends. A regression equation was determined which relates the cost of dredging to canal area, rate of siltation and average aggradations.

  7. Hypotension due to Chemotherapy in a Patient with Small Cell Lung Cancer and Lambert-Eaton Myasthenic Syndrome Undergoing Hemodialysis: A First Case Report

    2012-01-01

    Full Text Available We present the first case of small cell lung cancer with Lambert-Eaton myasthenic syndrome during hemodialysis (HD. A 72-year-old male patient receiving HD experienced progressive muscle weakness. He was diagnosed with small cell lung cancer with Lambert-Eaton myasthenic syndrome due to an increased serum level of anti-voltage-gated calcium channel antibody and aspiration cytology on endobronchial ultrasonography for the swelling of a subcarinal lymph node. He received chemotherapy consisting of carboplatin (300 mg/m2 and etoposide (50 mg/m2, to which he had a partial response. However, the second therapy course could not be administered because of the unexpected development of severe hematological adverse events, which also prevented him from undergoing further HD. This case indicates that caution should be taken when using chemotherapy for such patients because of hypotension due to chemotherapy, with which it is impossible to undergo HD.

    2017-01-01

    Full Text Available Marfan syndrome (MFS, the founding member of connective tissue disorder, is an autosomal dominant disease; it is caused by a deficiency of the microfibrillar protein fibrillin-1 (FBN1 and characterized by involvement of three main systems; skeletal, ocular, and cardiovascular. More than one thousand mutations in FBN1 gene on chromosome 15 were found to cause MFS. Nephrotic syndrome (NS had been described in very few patients with MFS being attributed to membranoproliferative glomerulonephritis secondary to infective endocarditis. Focal segmental glomerulosclerosis (FSGS had been reported in NS in conjunction with MFS without confirming the diagnosis by mutational analysis of FBN1. We hereby present an Egyptian family with MFS documented at the molecular level; it showed a male proband with NS secondary to FSGS, unfortunately, we failed to make any causal link between FBN dysfunction and FSGS. In this context, we review the spectrum of renal involvements occurring in MFS patients.

    A 58-year-old woman with calcinosis Raynaud esophageal sclerodactyly telangiectasia (CREST) syndrome presented with slowly progressive renal dysfunction. She was normotensive with normal plasma renin activity and lacking symptoms of vasculitis. Mild proteinuria was of tubular origin, but serological tests and an absence of sicca symptoms excluded the possibility of Sjögren's syndrome. Light microscopic study of renal biopsy showed interstitial fibrosis with ectasia and degeneration of proximal tubule and lymphocyte infiltration. There were no remarkable changes in the glomeruli. Chromatographic analysis of the Chinese herbs regimen that she had been taking for several years demonstrated aristolochic acid. She was diagnosed as Chinese herbs nephropathy. Therapy with oral prednisolone was markedly effective in improving renal function and anemia. To our knowledge, this is the first report of Chinese herbs nephropathy complicating connective tissue disease. It is important to consider the possibility of Chinese herbs nephropathy when patients treated with Chinese herbs develop renal dysfunction.

    Spinal stenosis is a narrowing of the spinal canal by a combination of bone and soft tissues, which can lead to mechanical compression of spinal nerve roots or the dural sac. The lumbal spinal compression of these nerve roots can be symptomatic, resulting in weakness, reflex alterations, gait disturbances, bowel or bladder dysfunction, motor and sensory changes, radicular pain or atypical leg pain and neurogenic claudication. The anatomical presence of spinal canal stenosis is confirmed radiologically with computerized tomography, myelography or magnetic resonance imaging and play a decisive role in optimal patient-oriented therapy decision-making. (orig.) [German] Die Spinalkanalstenose ist eine umschriebene, knoechern-ligamentaer bedingte Einengung des Spinalkanals, die zur Kompression der Nervenwurzeln oder des Duralsacks fuehren kann. Die lumbale Spinalkanalstenose manifestiert sich klinisch als Komplex aus Rueckenschmerzen sowie sensiblen und motorischen neurologischen Ausfaellen, die in der Regel belastungsabhaengig sind (Claudicatio spinalis). Die bildgebende Diagnostik mittels Magnetresonanztomographie, Computertomographie und Myelographie spielt eine entscheidende Rolle bei der optimalen patientenbezogenen Therapieentscheidung. (orig.)

    The Child Tourette Syndrome Impairment Scale (CTIM) rates 37 problems in school, social, and home domains separately for tics and for comorbid diagnoses. However, a shorter version would be easier to implement in busy clinics. Using published data from 85 children with Tourette syndrome, 92 controls, and parents, factor analysis was used to generate a "mini-CTIM" composed of 12 items applied to tic and comorbid diagnoses. Child- and parent-rated mini-CTIM scores were compared and correlated across raters and accounting for clinician-rated tic severity and presence of attention-deficit hyperactivity disorder (ADHD) and obsessive-compulsive disorder (OCD). The mini-CTIM achieved domain Cronbach alphas ranging from 0.71 to 0.94 and intra-item correlation coefficients ranging from 0.84 to 0.96. The resulting scale correlated with clinician-rated tic severity and reflected the presence of ADHD and OCD. The mini-CTIM appears promising as a practical assessment tool for tic- and non-tic-related impairment in children with Tourette syndrome.

    Revascularization of functionally non-significant stenoses in patients with stable coronary artery disease can safely be deferred as rate of adverse cardiovascular events is low. It is not clear whether fractional flow reserve (FFR) is just as accurate in acute coronary syndromes (ACS). The aim of this study is to assess the outcome of coronary lesions whose revascularization was deferred based on negative FFR values in subjects with ACS. Patients with acute coronary syndrome and showing at least one coronary stenosis whose revascularization was deferred based on FFR value >0.80 were included in the study. The primary endpoint of the study was the rate of target lesion failure (TLF), a composite of cardiac events (cardiac death, myocardial infarction and any coronary revascularization) related to the initially deferred stenosis at three-year follow-up. A total of 319 patients (237 male), mean age 68 [59-74] years and 355 coronary lesions with deferred revascularization based on negative FFR values (0.88±0.05) were selected. The rate of TLF was 6% at 1-year, 9% at 2-year and 12% at 3-year follow-up. TLF was driven by a new acute coronary syndrome in 75% of cases. The median time interval from FFR assessment to TLF was 457 [138-868] days. In patients with acute coronary syndrome, the rate of TLF of the initially deferred coronary stenoses is 12% at 3-year follow-up and TLF occurred because of a new ACS in three quarters of cases.

    Hypercalcemia of immobilization, while rare, may occur in adolescent boys after fracture. Although not fully understood, the mechanism appears to be related to bone turnover uncoupling, in part mediated by upregulation of RANKL. Animal studies suggest that parathyroidectomy suppresses RANKL-stimulated osteoclastogenesis in immobilized bone. Thus, immobilization-induced hypercalcemia should be uncommon in patients with hypoparathyroidism. We present a 15-year-old boy with well-controlled hypoparathyroidism who developed hypercalcemia and milk-alkali syndrome 5 weeks after sustaining a severe tibia/fibula fracture requiring bedrest. Milk-alkali syndrome (hypercalcemia, alkalosis, and renal insufficiency) results from chronic excessive ingestion of calcium and absorbable alkali. Prior to fracture, our patient had not experienced hypercalcemia despite high doses of supplements, necessary during puberty. Supplements were discontinued and his biochemistries normalized with saline diuresis and a dose of pamidronate. Alkaline phosphatase, which was low at presentation, returned to normal 5 weeks later with remobilization. Fracture and immobilization caused acute suppression of bone formation with persistent bone resorption in this rapidly growing adolescent; continuation of carbonate-containing calcium supplements resulted in the milk-alkali syndrome. Therefore, close monitoring of serum calcium with adjustments in supplementation are indicated in immobilized patients with hypoparathyroidism. © 2016 S. Karger AG, Basel.

    Fever of unknown origin (FUO) is a common clinical diagnostic dilemma. In the elderly, causes of FUO most commonly include malignancy or infection, and less commonly include collagen vascular diseases. Among the collagen vascular diseases causing FUO in the elderly, polymyalgia rheumatica/temporal arteritis, and adult Still's disease (adult juvenile rheumatoid arthritis) are difficult diagnoses to prove. Among the infectious causes of FUO in the elderly are subacute bacterial endocarditis, intra-abdominal abscesses, and extrapulmonary tuberculosis. In the elderly, neoplastic causes of FUO include lymphomas, hepatomas, renal cell carcinomas, and hepatic or central nervous system metastases. Acute leukemias, particularly during "blast" transformation, may present as acute fevers in the absence of infection, but are rare causes of FUO. Preleukemia/myelodysplastic syndromes are exceedingly rare causes of FUO. We present a case of an elderly man who presented with findings that initially suggested adult Still's disease. Prolonged and profound monocytosis provided the key clue to his subsequent diagnosis of preleukemia/myelodysplastic syndrome. In this patient, a positive Naprosyn test result also suggested a neoplastic cause for his FUO. After months of prolonged fevers, myelocytes/metamyelocytes were eventually demonstrated in his peripheral smear during hospital evaluation. These findings, in concert with the persistent monocytosis, highly elevated ferritin levels, polyclonal gammopathy on serum protein electrophoresis, and eventual presence of myelocytes/metamyelocytes on peripheral smear, prompted a bone marrow test that demonstrated blast cells confirming the diagnosis of preleukemia myelodysplastic syndrome as the cause of this patient's FUO.

    We report a 71-year-old man who had undergone pylorus-preserving pancreatoduodenectomy (PPPD) using PPPD-IV reconstruction for cholangiocarcinoma. For 6 years thereafter, he had suffered recurrent cholangitis, and also a right liver abscess (S5/8), which required percutaneous drainage at 9 years after PPPD. At 16 years after PPPD, he had been admitted to the other hospital because of acute purulent cholangitis. Although medical treatment resolved the cholangitis, the patient was referred to our hospital because of dilatation of the intrahepatic biliary duct (B2). Peroral double-balloon enteroscopy revealed that the diameter of the hepaticojejunostomy anastomosis was 12 mm, and cholangiography detected intrahepatic stones. Lithotripsy was performed using a basket catheter. At 1 year after lithotripsy procedure, the patient is doing well. Hepatobiliary scintigraphy at 60 minutes after intravenous injection demonstrated that deposit of the tracer still remained in the upper afferent loop jejunum. Therefore, we considered that the recurrent cholangitis, liver abscess, and intrahepatic lithiasis have been caused by biliary stasis due to nonobstructive afferent loop syndrome. Biliary retention due to nonobstructive afferent loop syndrome may cause recurrent cholangitis or liver abscess after hepaticojejunostomy, and double-balloon enteroscopy and hepatobiliary scintigraphy are useful for the diagnosis of nonobstructive afferent loop syndrome.

    Full Text Available Community-acquired methicillin-resistant Staphylococcus aureus has been spreading worldwide, including in Japan. However, few cases of toxic shock syndrome caused by Community-acquired methicillin-resistant Staphylococcus aureus have been reported in Japan. We report 2 cases, in middle-aged women, of toxic shock syndrome due to Community-acquired methicillin-resistant Staphylococcus aureus via a vaginal portal of entry. The first patient had used a tampon and the second patient had vaginitis due to a cleft narrowing associated with vulvar lichen sclerosus. Both patients were admitted to our hospital with septic shock and severe acute kidney injury and subsequently recovered with appropriate antibiotic treatment. In our review of the literature, 8 cases of toxic shock syndrome caused by Community-acquired methicillin-resistant Staphylococcus aureus were reported in Japan. In these 8 cases, the main portals of entry were the skin and respiratory tract; however, the portal of entry of Community-acquired methicillin-resistant Staphylococcus aureus from a vaginal lesion has not been reported in Japan previously.

  8. Root Canal Filling after Revascularization/Revitalization.

    Science.gov (United States)

    Plascencia, Hugo; Cruz, Álvaro; Díaz, Mariana; Jiménez, Ana Laura; Solís, Rodrigo; Bernal, Cesar

    Revascularization/revitalization therapy is considered an alternative procedure for management of teeth with an immature apex and necrotic pulp, mainly when root development is interrupted in the early phases of formation. However, this clinical treatment protocol should be considered a permanent procedure? A maxillary central incisor with a previous and successful RR treatment was intentionally filled with a biocompatible material with the periapical tissues due to the patient's lack of adherence to the follow-up protocol. The 20-month follow-up showed absence of clinical, radiological and tomographic signs and symptoms of an endodontic re-infection. This case demonstrates that once the increased thickening of the canal walls, incrementing the root length, apical closure and the total resolution of the apical lesion are observed, the main canal of a previously treated tooth with an RR procedure can be filled.

    In a consecutive series of minor surgical specimens from the anal canal, neuronal hyperplasia was found in nine of 56 haemorrhoidectomy specimens and in four of 23 fibrous polyps. In an additional series of 14 resections of the anal canal, neuronal hyperplasia was present in six cases, of which...... five showed haemorrhoids. In all cases, neuronal hyperplasia was located in the submucosa beneath squamous epithelium and extended over an area from 5 to 12 mm. Immunohistochemically, the foci of hyperplasia were found to consist of both neuronal and Schwann cell components. Staining for vasoactive...... intestinal peptide, neuropeptide Y and calcitonin gene related peptide, did not demonstrate any increased terminal density. It is suggested that anal neuronal hyperplasia in these cases represents an acquired lesion due to local mechanical influence....

    Full Text Available Objective: To compare and contrast our experience with middle cranial fossa approach (MFR and transmastoid approach with capping of the dehiscence (TMR of superior semicircular canal dehiscence and to determine guidelines to help guide management of these patients. Methods: All patients from 2005 to 2014 with symptomatic superior semicircular canal dehiscence syndrome with dehiscence demonstrated on CT scan of the temporal bone who underwent surgical repair and had a minimum 3 months of follow up. Surgical repair via the MFR or TMR, preoperative CT temporal bone, preoperative, and postoperative cervical vestibular evoked myogenic potential (cVEMP testing and anterior canal video head thrust testing (vHIT. Success of repair was stratified as complete success, moderate success, mild success, or failure based on resolution of all symptoms, the chief complaint, some symptoms, or no improvement, respectively. Results: A total of 29 ears in 27 patients underwent surgical repair of canal dehiscence. Complete or moderate success was seen in 71% of the MFR group compared to 80% of the TMR group. There were zero failures with the MFR group and no major intracranial complications. There were 2 failures out of 15 ears that underwent the TMR. Residual symptoms were most commonly vertigo or disequilibrium in the MFR and aural fullness or autophony in the TMR groups, respectively. MFR hospital stay was approximately 2 days longer. Average cVEMP threshold shifted 18 dB with surgical correction in the MFR group. A 29 dB average shift was seen in the TMR group. The MFR group had a significant reduction in their anterior canal gain compared to the TMR group. Conclusions: TMR is a less invasive alternative to MFR. However, in our series, we have not seen any intracranial complications (aphasia, stroke, seizures, etc. in our MFR patients. Interestingly, vestibular symptoms were better addressed than audiological symptoms by the TMR suggesting its usefulness as a

    Full Text Available The risk of infective endocarditis in chronic hemodialysis patients is markedly higher than that in the general population. We report the first case of a hemodialysis patient with infective endocarditis caused by Streptococcus dysgalactiae subsp. equisimilis (SDSE who presented with streptococcal toxic shock syndrome. In the last decade, there has been an increase in the incidence of SDSE infections. Therefore, it is important to recognize SDSE as a possible causative agent of infective endocarditis in an immunocompromised population, such as hemodialysis patients.

    Atypical haemolytic uraemic syndrome (aHUS) is caused by dysregulated complement activation. A humanised anti-C5 monoclonal antibody has recently become available for treatment of this condition We present the first description of an infant with an activating mutation of complement factor B successfully treated with eculizumab. On standard doses she had evidence of ongoing C5 cleavage despite a good clinical response. Eculizumab is effective therapy for aHUS associated with factor B mutations, but recommended doses may not be adequate for all patients.

  13. Management of the Nasopalatine Canal and Foramen Associated With Dental Implant Therapy.

    2016-06-01

    In some patients, the contents of the nasopalatine canal must be removed to facilitate placement of a dental implant into the canal. Reasons to enucleate the canal in preparation for a bone graft or a dental implant include inadvertent perforation into the canal when creating an osteotomy for an implant, severe atrophy of the maxilla, and a large foramen that precludes placing an implant into the desired location along the bony ridge. The authors searched the dental literature for clinical reports in humans that addressed placement of dental implants into or adjacent to the nasopalatine canal. They found that the nasopalatine canal is usually around 10-mm long and 4-mm wide and slants from the horizontal plane at a 66-degree angle, and there is considerable variation regarding these measurements. Several clinical reports demonstrate that the canal can be enucleated and bone grafted before successful implant placement. It is also possible to place an implant into the canal at the time of surgery and this procedure may or may not be combined with an adjunctive bone graft. Numerous case reports indicate there is usually no permanent loss of sensation of the anterior palate when an implant is placed into the nasopalatine canal. The authors concluded that placing an implant into the nasopalatine canal is a viable procedure as part of a surgical and prosthetic treatment plan when there is a dearth of alternate sites for implant placement. In patients with severe atrophy of the maxilla, combination syndrome, or who have a large or malpositioned nasopalatine canal, the canal can be used as a site to place a dental implant to support a fixed or removable dental prosthesis.

    2012-01-01

    Full Text Available A 68-year-old Caucasian female with a past medical history of a deceased donor kidney transplant four months prior was admitted with a two-day history of anuria and acute kidney injury. A renal ultrasound demonstrated thrombus in the transplanted kidney's renal vein that extended into the left iliac vein as well as into the left femoral venous system. Catheter-guided tissue thrombolytics were infused directly into the clot. Within twelve hours of initiating thrombolytic infusion, there was brisk urine output. Interval venography demonstrated decreasing clot burden. At the time of discharge her creatinine was 0.78 mg/dL, similar to her baseline value prior to presentation. The patient was noted to have May-Thurner syndrome on intravascular ultrasound (IVUS. Angioplasty followed by stent placement was done. Unique to our case report was the timing of the presentation of renal vein thrombosis (four months after transplant and the predisposing anatomy consistent with May-Thurner syndrome, which was diagnosed with IVUS and successfully treated with local thrombolytics.

    Full Text Available Abstract Background Leiomyomas of the deep soft tissue are quite uncommon and occur even more rarely in upper extremity. Case presentation A 32-year old manual laborer man presented with a two-year history of numbness, tingling and burning pain in the palmar surface of the left hand and fingers. His medical history was unremarkable and no trauma episode was reported. According to the clinical examination and the result of median nerve conduction study (NCS the diagnosis of carpal tunnel syndrome was established. Operative release of the transverse carpal ligament was subsequently performed but the patient experienced only temporary relief of his symptoms. MRI examination revealed a deep palmary located mass with well-defined margins and ovoid shape. Intraoperatively, the tumor was in continuity with the flexor digitorum superficialis tendon of the middle finger causing substantial compression to median nerve. Histopathological findings of the resected mass were consistent with leiomyoma. After two years the patient was pain-free without signs of tumor recurrence. Conclusion Despite the fact that reports on deep soft tissue leiomyoma are exceptional, this tumor had to be considered as differential diagnosis in painful non-traumatic hand syndromes especially in young patients.

    Breast cancer-related lymphedema often causes cellulitis and is one of the most common complications after breast cancer surgery. Streptococci are the major pathogens underlying such cellulitis. Among the streptococci, the importance of the Lancefield groups C and G is underappreciated; most cases involve Streptococcus dysgalactiae subspecies equisimilis. Despite having a relatively weak toxicity compared with group A streptococci, Streptococcus dysgalactiae subspecies equisimilis is associated with a mortality rate that is as high as that of group A streptococci in cases of invasive infection because Streptococcus dysgalactiae subspecies equisimilis mainly affects elderly individuals who already have various comorbidities. An 83-year-old Japanese woman with breast cancer-related lymphedema in her left upper limb was referred to our hospital with high fever and acute pain with erythema in her left arm. She showed septic shock with disseminated intravascular coagulation. Blood culture showed positive results for Streptococcus dysgalactiae subspecies equisimilis, confirming a diagnosis of streptococcal toxic-shock syndrome. She survived after successful intensive care. To the best of our knowledge, this case represents the first report of Streptococcus dysgalactiae subspecies equisimilis-induced streptococcal toxic-shock syndrome in a patient with breast cancer-related lymphedema. Breast cancer-related lymphedema is a common problem, and we must pay attention to invasive streptococcal soft tissue infections, particularly in elderly patients with chronic disease.

    Aicardi-Goutieres syndrome is a rare progressive subacute encephalopathy of early onset - generally in the first year of life - characterised by psychomotor retardation, microcephaly, alterations in the white matter of the brain, intracranial calcifications, pleocytosis and elevated levels of interferon alpha in the cerebrospinal fluid. It is associated to an increase in the expression of genes stimulated by interferon in peripheral blood, a fact known as the interferon signature. The levels of genes stimulated by interferon has been postulated as a good biomarker, as they remain high in peripheral blood over time and are more sensitive, in comparison to determinations of interferon alpha and neopterins in cerebrospinal fluid, which descend as of one year of life. To date, mutations have been reported in seven genes that overstimulate the interferon alpha pathway, and the last to be discovered is IFIH1 (interferon induced with helicase C domain 1), with a pattern of dominant autosomal inheritance. We present the first case reported in the Hispanic literature caused by a de novo mutation in the IFIH1 gene. The clinical features, studies conducted and review of the clinical, neuroradiological and genetic aspects are described. The inheritance of the mutations reported for Aicardi-Goutieres syndrome was classically considered as being recessive autosomal, but these findings show that dominant autosomal mutations in the IFIH1 gene can cause the disease. As a previously unreported neuroimaging finding, it presents a lesion consisting in cystic encephalomalacia in the pons.

    Full Text Available The use of conventional cytogenetic techniques in combination with fluorescent in situ hybridization (FISH and single-nucleotide polymorphism (SNP microarrays is necessary for the identification of cryptic rearrangements in the diagnosis of chromosomal syndromes. We report two siblings, a boy of 9 years and 9 months of age and his 7-years- and 5-month-old sister, with the classic Wolf-Hirschhorn syndrome (WHS phenotype. Using high-resolution GTG- and NOR-banding karyotypes, as well as FISH analysis, we characterized a pure 4p deletion in both sibs and a balanced rearrangement in their father, consisting in an insertion of 4p material within a nucleolar organizing region of chromosome 15. Copy number variant (CNV analysis using SNP arrays showed that both siblings have a similar size of 4p deletion (~6.5 Mb. Our results strongly support the need for conventional cytogenetic and FISH analysis, as well as high-density microarray mapping for the optimal characterization of the genetic imbalance in patients with WHS; parents must always be studied for recognizing cryptic balanced chromosomal rearrangements for an adequate genetic counseling.

    2009-06-01

    Lumbar canal stenosis (LCS) is a degenerative disease involving the lumbar vertebrae, discs, and ligamentum flavum that result in neurological deficit to some extent. The natural history of symptoms of LCS is highly important because they do not necessarily worsen with progressive degeneration. Therefore, a observation therapy is adopted for the treatment of this condition. Although invasive treatment is required for some patients, surgery cannot be performed solely on the basis of radiological findings and careful evaluation of neurological symptoms is necessary. In the event that spinal surgery is required, it is important to minimize degree of invasiveness; various devices and operative approaches and methods have been developed to this end. Our strategy for the surgical treatment of LCS involves microscopic decompression via a posterior approach. In our method, modified bilateral decompression via the splitting of the spinous process using an ultrasonic bone curette (SONOPET), and the results of this approach have been excellent. Our method is less invasive, facilitates the preservation of the paraspinal muscle, and represents a useful approach to posterior spinal elements. Our findings indicate that this method involves less muscle damage as compared to other methods. LCS should be differentiated from conditions other than those involving the spinal canal such as foraminal stenosis and far-out syndrome, piriformis syndrome, and tarsal tunnel syndrome. The incidence of these conditions is higher than appreciated and they present with neurological deficits similar to observed in LCS. Here, we report our criteria of operative indications for surger and the procedures that we developed for the treatment of LCS, based on a review of the available literature.

    2017-02-18

    Fusion of the atlas with the occipital bone is a rare congenital dysplasia known as occipitalization of the atlas, occipitocervical synostosis, assimilation of the atlas, or atlanto-occipital fusion. It is a component of the paraxial mesodermal maldevelopment and commonly associated with other dysplasias of the craniovertebral junction. External auditory canal atresia or external aural atresia is a rare congenital absence of the external auditory canal. It occurs as the consequence of the maldevelopment of the first pharyngeal cleft due to defects of cranial neural crest cells migration and/or differentiation. It is commonly associated with the dysplasias of the structures derived from the first and second pharyngeal arches including microtia. We present the coexistence of the occipitalization of the atlas and congenital aural atresia, an uncommon combination of the paraxial mesodermal maldevelopment, and defects of cranial neural crest cells. The association is most probably syndromic as minimal diagnostic criteria for the oculoariculovertebral spectrum are fulfilled. From the clinical point of view, it is important to be aware that patients with microtia must obtain also appropriate diagnostic imaging studies of the craniovetebral junction due to eventual concomitant occipitalization of the atlas and frequently associated C1-C2 instability.

    2010-01-01

    Via our description of a seemingly heterogeneous group of four patients who presented to our rehabilitation facility with a rather unusual clinical presentation of compartment syndrome with development of a flaccid paraparesis and rhabdomyolysis immediately after awakening from a prolonged sleep episode in an unusual posture - which might, in fact, be a 'new syndrome' - we have also come to address an important issue linking our group of patients - specifically, the complexities which present to a rehabilitative facility in the cases of unusual and unclear diagnoses. Eventually, all four of our patients remained severely disabled. All had suffered sensorimotor axonal demyelinative polyneuropathies and two patients had subclinical hypothyroidism. Prior to the prolonged sleep episode, they had all consumed alcohol and drugs. Using these four rather demanding diagnostic rehabilitative cases we address the ever-important issue of timely mutual communication and patience. For when a rehabilitative facility is confronted with patients whose diagnoses are not clear, the scope of the long-term comprehensive rehabilitation management faces some major obstacles with respect to how the rehabilitative team can succeed in designing a 'tailor-made' rehabilitation program for these patients, which often-times proves to be a rather tricky task requiring innovative and creative efforts on the parts of all those involved in the care of the patient. Quite a challenging task, indeed, yet one genuinely necessary to attempt to achieve so that the patient, family and, of course, the 'payer agency/provider' can all prepare themselves, realistically so as to obtain the best overall rehabilitative outcome for these patients. We conclude that what is most necessary for these unique patients is patience.

    2016-08-01

    Persistent post-concussion syndrome caused by mild traumatic brain injury has become a major cause of morbidity and poor quality of life. Unlike the acute care of concussion, there is no consensus for treatment of chronic symptoms. Moreover, most of the pharmacologic and non-pharmacologic treatments have failed to demonstrate significant efficacy on both the clinical symptoms as well as the pathophysiologic cascade responsible for the permanent brain injury. This article reviews the pathophysiology of PCS, the diagnostic tools and criteria, the current available treatments including pharmacotherapy and different cognitive rehabilitation programs, and promising new treatment directions. A most promising new direction is the use of hyperbaric oxygen therapy, which targets the basic pathological processes responsible for post-concussion symptoms; it is discussed here in depth.

    Full Text Available A 34-year-old Japanese woman was admitted to our hospital complaining of developing bilateral pedal edema. Imaging studies led to a diagnosis of Budd-Chiari syndrome combined with internal jugular vein thrombus. We investigated the cause of thrombosis and found that the anticoagulant activity of protein C was decreased. Genetic analysis showed the presence of a c.125C>A (Arg42Ser substitution in the protein C gene (PROC of the proband, which generates an Arg42Ser mutation that replaces the scissile bond Arg42-Ala43 normally cleaved by a furin-like processing protease. Her father and younger brother also carried this mutation, although they had no evidence of thrombosis.

    Water drinking recently has been shown to raise blood pressure in normal subjects and in patients with autonomic failure who have orthostatic hypotension. However, in normal young subjects, ingestion of approximately 500 ml has no pressor effect; but in older subjects there is an increase in blood pressure. An even greater rise in blood pressure occurs in cases with autonomic failure. The possible mechanisms responsible for the pressor response to water include neural and humoral factors; fluid redistribution also needs to be considered. This review will concentrate on the water pressor response in normal subjects and different groups of patients with autonomic diseases who have orthostatic intolerance, on the mechanisms that could be involved, and on whether this pressor response may be used in the management of orthostatic hypotension, vasovagal syncope and the postural tachycardia syndrome.

    Epigenetic alterations at several maternal loci have been associated with imprinting disorders in children conceived using assisted reproductive technologies. To date, epimutations at paternal loci have been observed in the spermatozoa of infertile men, but there is little evidence of paternal epimutations in babies conceived using assisted reproductive treatment. This is a report of a female infant with classic Russell-Silver Syndrome (RSS) who was conceived using intracytoplasmic injection of spermatozoa obtained from testicular aspiration. Methylation studies revealed hypomethylation of the paternally derived H19/IGF2 locus. As far as is known, this is the second assisted reproduction treatment-conceived patient with classic RSS and this epigenotype. This case provides further evidence that epimutations affecting paternal alleles might be associated with assisted reproductive treatment. 2010 Reproductive Healthcare Ltd. All rights reserved.

    Ritonavir and cobicistat, used as pharmacokinetic enhancers in combination with some antiretrovirals (ARVs) for the treatment of HIV, are potent inhibitors of the CYP3A4 isoenzyme. Most glucocorticoids are metabolised via the CYP3A4 pathway and iatrogenic Cushing's syndrome (ICS), with possible secondary adrenal insufficiency (SAI), is a recognised complication following co-administration with ritonavir or cobicistat. A structured approach for identifying and managing potentially affected individuals has not been established.We systematically identified patients with ICS/SAI and found substantial heterogeneity in clinical practice across three large London HIV centres. While this significant drug interaction and its complications are now well-recognised, it is apparent that there is no standardised approach to management or guidance for the general physician. Here we describe the management of ICS/SAI in our current practice, review the available evidence and suggest practice recommendations. © Royal College of Physicians 2016. All rights reserved.

    The authors report an unusual case of flexor tenosynovitis, severe carpal tunnel syndrome, and triggering at the carpal tunnel as the first manifestation of gout. A 69-year-old man presented with digital flexion contracture and severe carpal tunnel syndrome of his right hand and was treated surgically. A flexor tenosynovectomy and a median nerve neurolysis were performed through an extended carpal tunnel approach. The sublimis and the profundus tendons were involved. Partial ruptures and multiple whitish lesions suggestive of tophacceous infiltration of the flexor tendons were seen. Macroscopically, the removed synovial tissue was involved by multiple whitish nodules that were milimetric in size and was suggestive of monosodium urate crystals deposits. By light microscopy examination, numerous nonnecrotizing granulomas of different sizes were observed that were compounded by large aggregations of acellular nonpolarized material, surrounded by epithelioid histiocytes, mononuclear cells, and foreign body multinucleated giant cells. Postoperatively, the patient recovered with resolution of the median nerve symptoms and a near-to-full range of motion of the affected digits.To the authors' knowledge, this patient is the first case report with flexor tendons tophacceous infiltration as the first clinical sign of gout. Gouty flexor tenosynovitis can occur in the absence of a long history of gout. A high index of suspicion is paramount to the initiation of proper management. Operative treatment of gouty flexor tenosynovitis is mandatory to debulk tophaceous deposits, improve tendon gliding, and decompress nerves. Routine uric acid determination could be helpful in the preoperative evaluation of patients with flexor tenosynovitis. Copyright 2011, SLACK Incorporated.

    Full Text Available Radix Astragali (RA with slight sweet and warm property is a significant “qi tonifying” herb; it is indicated for the syndrome of dampness stagnancy due to spleen deficiency (DSSD. The purpose of this research was to explore effects of RA and its split components on gene expression profiles related to water metabolism in rats with the DSSD syndrome for identifying components representing property and flavor of RA. The results indicated that RA and its split components, especially polysaccharides component, significantly increased the body weight and the urine volume and decreased the water load index of model rats. Our data also indicated differentially expressed genes (DEGs related to water metabolism involved secretion, ion transport, water homeostasis, regulation of body fluid levels, and water channel activity; the expression of AQP1, AQP3, AQP4, AQP5, AQP6, and AQP8 was improved; calcium, cAMP, MAPK, PPAR, AMPK, and PI3K-Akt signaling pathway may be related to water metabolism. In general, results indicate that RA and its split components could promote water metabolism in rats with the DSSD syndrome via regulating the expression of AQPs, which reflected sweet-warm properties of RA. Effects of the polysaccharides component are better than others.

    We wanted to report the CT image findings of the osteoma of the external auditory canal. Temporal bone CT scanning was performed on eight patients (4 males and 4 females aged between 8 and 41 years) with pathologically proven osteoma of the external auditory canal after operation, and the findings of the CT scanning were retrospectively reviewed. Not only did we analyze the size, shape, distribution and location of the osteomas, we also analyzed the relationship between the lesion and the tympanosqumaous or tympanomastoid suture line, and the changes seen on the CT scan images for the patients who were able to undergo follow-up. All the lesions of the osteoma of the external auditory canal were unilateral, solitary, pedunculated bony masses. In five patients, the osteomas occurred on the left side and for the other three patients, the osteomas occurred on the right side. The average size of the osteoma was 0.6 cm with the smallest being 0.5 cm and the largest being 1.2 cm. Each of the lesions was located at the osteochondral junction in the terminal part of the osseous external ear canal. The stalk of the osteoma of the external auditory canal was found to have occurred in the anteroinferior wall in five cases (63%), in the anterosuperior wall (the tympanosqumaous suture line) in two cases (25%), and in the anterior wall in one case. The osteoma of the external auditory canal was a compact form in five cases and it was a cancellous form in three cases. One case of the cancellous form was changed into a compact form 35 months later due to the advanced ossification. Osteoma of the external auditory canal developed in a unilateral and solitary fashion. The characteristic image findings show that it is attached to the external auditory canal by its stalk. Unlike our common knowledge about its occurrence, osteoma mostly occurred in the tympanic wall, and this is regardless of the tympanosquamous or tympanomastoid suture line.

    Full Text Available Hypoparathyroidism is most commonly isolated and idiopathic. Hypoparathyroidism in autoimmune polyendocrine syndrome type-2 (APS-2 is extremely rare with few isolated reports and usually presents late. We present perhaps for the first time, hypoparathyroidism being the initial manifestation of APS-2 which was diagnosed in a 32 year lady with tingling of the extremities along with hypocalcemic tetany for 15 years. She also had generalized acral and mucosal hyperpigmentation of 2 years duration. Investigations were significant for low calcium (7.1mg/dl, elevated phosphorus (4.8mg/dl, vitamin-D insufficiency (27.4ng/ml, low intact parathyroid hormone (2.3pg/ml, low basal (4.7mcg/dl and stimulated serum cortisol (9.2mcg/dl at half hour, 11.4mcg/dl at 1 hour post synacthen, elevated triiodothyronine (2.1ng/ml and free tetraiodothyronine (2.4ng/dl along with suppressed TSH (<0.005 U/L. Imaging relevaled mild cerebellar calcification, normal adrenals with diffuse uptake of Tc 99 - pertechnate. A diagnosis of hypoparathyroidism with Addison′s and Graves′ disease as a part of APS-2 was made. This report intends to highlight the clinical heterogeneity and varied presentation of APS-2. Routine screening of other hormonal function (especially adrenal function, thyroid function and blood glucose in a patient with diagnosed hypoparathyroidism is advisable to decrease the chances of missing APS-2.

    We experienced a 10-year-old boy who had anaphylaxis after eating rose-flavored soft-serve ice cream. The patient felt a sense of discomfort in his throat when eating apple, peach, loquat, Japanese pear, and kiwi fruit. Therefore, we measured specific IgE antibodies to allergen components by ImmunoCAP ISAC. Consequently, the patient gave positive results for all PR-10 proteins from birch, alder, hazel, apple, peach, peanut, hazelnut, and soybean, so we diagnosed him with Pollen Food Allergy Syndrome (PFAS) induced by cross reactivity with pollens of birch family and fruits of rose family. When we conducted the skin prick test as is for red rose syrup because of the belief that anaphylaxis was caused by the rose ingredient contained in rose-flavored soft-serve ice cream, the patient gave a strong positive result. However, the results were negative for rose essence and Food Red No. 2 contained. Subsequently, it was found that red rose syrup contained apple juice. Therefore, we conducted the prick-prick test for apple, and the patient was confirmed to be strongly positive to apple. We thus identified apple as the cause of anaphylaxis. Since there is no legal obligation of labeling specific raw materials when directly selling manufactured and processed food products to general consumers, it is possible for general consumers to mistakenly take them in without knowing the containment of allergic substances. It is believed that the labeling method should be improved in the future.

    Uniparental disomy has recently been recognized to cause human disorders, including Prader-Willi syndrome (PWS). The authors describe a particularly instructive case which raises important issues concerning the mechanisms producing uniparental disomy and whose evaluation provides evidence that trisomy may precede uniparental disomy in a fetus. Chorionic villus sampling performed for advanced maternal age revealed trisomy 15 in all direct and cultured cells, though the fetus appeared normal. Chromosome analysis of amniocytes obtained at 15 wk was normal in over 100 cells studied. The child was hypotonic at birth, and high-resolution banding failed to reveal the deletion of 15q11-13, a deletion which is found in 50%-70% of patients with PWS. Over time, typical features of PWS developed. Molecular genetic analysis using probes for chromosome 15 revealed maternal disomy. Maternal nondisjunction with fertilization of a disomic egg by a normal sperm, followed by loss of the paternal 15, is a likely cause of confined placental mosaicism and uniparental disomy in this case of PWS, and advanced maternal age may be a predisposing factor. 38 refs., 3 figs., 2 tabs.

  19. Is Efficacy of the Anti-Cd20 Antibody Rituximab Preventing Hemolysis Due to Passenger Lymphocyte Syndrome?

    2017-02-01

    Passenger lymphocyte syndrome (PLS) often occurs after ABO-mismatched solid organ and/or bone marrow transplantation between a donor and recipient. Viable donor B-lymphocytes transferred during organ transplantation produce antibodies against recipient red cell antigens, leading to hemolysis. The incidence of PLS has been reported to be around 9% after renal transplantation. A previous report showed that rituximab (Rit) was useful for treatment of PLS in allogeneic stem cell transplantation, bowel transplant and severe cases of hemolysis. However, the effectiveness of Rit in preventing PLS after renal transplantation has not yet been evaluated. The participants in this study were 85 patients who had undergone ABO-mismatched renal transplantation from January 2005 to April 2013. Rit was administered to these patients before transplantation. None of the patients that received Rit treatment developed PLS. Thus administration of Rit before transplantation effectively controlled the production of antibodies by B-lymphocytes, which probably prevented the development of PLS. © 2016 International Society for Apheresis, Japanese Society for Apheresis, and Japanese Society for Dialysis Therapy.

    Full Text Available A 22-year-old male came to casualty on 5 th May 2012 after a fall from motorcycle. He complained of excruciating pain and swelling over right knee. There was an open wound of 7 × 2 cm over supra-patellar region and diffuse swelling over knee joint with severe tenderness over proximal aspect of right tibia. X-ray showed intra-articular fracture of proximal tibia extending to diaphysis classified as type 6 by Schatzker classification for proximal tibia, with fibula shaft transverse fracture. The skin over the fracture was contused. Debridement with primary wound closure was done in emergency. Skeletal traction was applied through a lower tibial Steinman pin. Patient was operated after 15 days when wound healed and swelling subsided. Locking plate was applied on medial aspect using Minimally invasive percutaneous plate osteosysthesis (MIPPO technique. Post-operatively over 4 hours patient developed severe pain and swelling in operated leg which mimicked compartment syndrome. Suture removal was done immediately in the ward from the distal aspect, which relieved the symptoms but lead to exposure of the plate. A rotational flap was done to cover the plate in coordination with a plastic surgeon on the next day.

    Crouzon’s syndrome is the commonest variety of syndromic craniosynostosis. Life-threatening ear bleed due to ruptured jugular venous diverticulum in Crouzon’s syndrome has not been described previously. In patients with syndromic craniosynostosis, definitive repair of jugular diverticulum by open surgery is fraught with high risk of bleeding, poor functional outcomes, and even death. A 24-year-old woman with Crouzon’s syndrome presented with conductive hearing loss and recurrent episodes of torrential bleeding from her left ear. On computed tomography, a defect in the roof of jugular fossa containing jugular venous diverticulum immediately inferior to the bony external auditory canal was seen. The clinical presentation, imaging features, and endovascular management of Crouzon’s syndrome due to a ruptured jugular venous diverticulum is described.

    To study transition zones from normal to abnormal retina in Usher syndrome IB (USH1B) caused by myosin 7A (MYO7A) mutations. Optical coherence tomography (OCT) scattering layers in outer retina were segmented in patients (n = 16, ages 2-42; eight patients had serial data, average interval 4.5 years) to quantify outer nuclear layer (ONL) and outer segments (OS) as well as the locus of EZ (ellipsoid zone) edge and its extent from the fovea. Static perimetry was measured under dark-adapted (DA) and light-adapted (LA) conditions. Ellipsoid zone edge in USH1B-MYO7A could be located up to 23° from the fovea. Ellipsoid zone extent constricted at a rate of 0.51°/year with slower rates at smaller eccentricities. A well-defined EZ line could be associated with normal or abnormal ONL and/or OS thickness; detectable ONL extended well beyond EZ edge. At the EZ edge, the local slope of LA sensitivity loss was 2.6 (±1.7) dB/deg for central transition zones. At greater eccentricities, the local slope of cone sensitivity loss was shallower (1.1 ± 0.4 dB/deg for LA) than that of rod sensitivity loss (2.8 ± 1.2 dB/deg for DA). In USH1B-MYO7A, constriction rate of EZ extent depends on the initial eccentricity of the transition. Ellipsoid zone edges in the macula correspond to large local changes in cone vision, but extramacular EZ edges show more pronounced losses on rod-based vision tests. It is advisable to use not only the EZ line but also other structural and functional parameters for estimating natural history of disease and possible therapeutic effects in future clinical trials of USH1B-MYO7A.

    Cardiorenal syndrome type 5 (CRS-5) includes a group of conditions characterized by a simultaneous involvement of the heart and kidney in the course of a systemic disease. Systemic sclerosis (SSc) is frequently involved in the etiology of acute and chronic CRS-5 among connective tissue diseases. In SSc patients, left ventricular mass (LVM) can be used as a marker of nutritional status and fibrosis, while altered intrarenal hemodynamic parameters are suggestive of early kidney involvement. Forty-two consecutive patients with a diagnosis of SSc without cardiac and/or renal impairment were enrolled to assess whether cardiac muscle mass can be related to arterial stiffness. Thirty subjects matched for age and sex were also enrolled as healthy controls (HC). All patients performed echocardiography and renal ultrasound. Doppler indices of intrarenal stiffness and echocardiographic indices of LVM were significantly increased in SSc patients compared to HC. A positive correlation exists between LVM/body surface area and pulsatile index (p < 0.05, r = 0.36), resistive index (p < 0.05, r = 0.33) and systolic/diastolic ratio (p < 0.05, r = 0.38). Doppler indices of intrarenal stiffness and LVM indices were significantly higher in SSc patients with digital ulcers than in SSc patients without a digital ulcer history. SSc is characterized by the presence of microvascular and multiorgan injury. An early cardiac and renal impairment is very common. LVM and intrarenal arterial stiffness can be considered as early markers of CRS onset. The clinical use of these markers permits a prompt identification of organ damage. An early diagnosis allows the appropriate setting of pharmacological management, by slowing disease progression. © 2016 S. Karger AG, Basel.

    Reactive hypoglycemia induced by late dumping syndrome is often observed after gastrectomy. However, no effective therapy has yet been fully established. We herein describe a case in which concurrent therapy with a low-carbohydrate diet using low-glycemic-index food and an alpha-glucosidase inhibitor, miglitol, very effectively ameliorated the postprandial fluctuations in the blood glucose and plasma insulin levels in a patient with reactive hypoglycemia due to late dumping syndrome following total gastrectomy. The administration of miglitol under a low-carbohydrate diet using low-glycemic-index food may therefore be an ideal treatment for reactive hypoglycemia due to late dumping syndrome.

    The research investigates the field methodologies to evaluate water losses from canals, in order to find a reliable method to identify and quantify them. This study was conducted in five canal lines in Piedmont, north-western Italy, different for hydraulic, morphological, geological and hydrogeological contexts (De Luca et alii, 2012). At a regional scale, Piedmont network consists of several tens of thousands km of irrigation canals. The loss of water due to seepage from irrigation canals constitutes a substantial part of the usable water. Irrigation canals placed in natural soil or fine and coarse sediments are characterized by water losses ranging from 20 % to more than 50 %. These losses cause economic, hydrogeological and environmental consequences: water losses evaluation from irrigation canals in the basis for the sustainable water resource use and management. First, hydrogeological and hydrological characterisation of the study area and of the bottom of the irrigation canals was carried out for every investigated canal, in order to evaluate the relationships between groundwater and stream water (eg. piezometric and hydrogeochemical survey campaigns, infiltrometry tests, penetrometric tests and electrical tomographies, soil characterizations from the bottom of investigated canals). The canals seepage rates were subsequently estimated using different methodologies: empirical formulas, inflow-outflow tests and double tracer tests. The empirical formulas applied for the study underestimated the real amount of the losses probably due to the scarce number of the considered variables. Then the canals seepage rates were evaluated employing inflow-outflow tests, considered the best tool by several authors. This method allows the determination of seepage quantities measuring inflow and outflow of a canal test reach either by instruments. The canal discharge was evaluated using a current meter. This method, even if easy to apply and practical, is not efficient

    Full Text Available The Atazar Canal helps to supply Madrid with water, from the rivers Lozoya, Jarama and Sorbe. The section which operates at present starts at the Torrelaguna dam and finishes at the El Goloso reservoir. Later a further section will be added, from the Atazar dam, on the Lozoya river, to link up with the control dam at Torrelaguna. The canal capacity is 16 m3/sec, and it is 43.47 km long. It has a slope of 4/10.000. The cross section is similar to that of the Jarama canal, already built. There are interconnections between this canal and the Canal Alto, which previously supplied the high and medium part of Madrid. To overcome the ground unevenness 5 syphons have been built, the most important of which is the Colmenar Goloso syphon, which is 10.88 km in length. Construction commenced on December 10, 1962, and water reached Madrid on June 15th, 1966. The initial budget for this project was 1,500 million pesetas.El canal del Atazar refuerza considerablemente el abastecimiento de aguas a Madrid, procedentes de los ríos Lozoya, Jarama y, en un próximo futuro, del Sorbe. El tramo, actualmente en funcionamiento, empieza en el salto de Torrelaguna y finaliza en los depósitos de El Goloso. Más adelante se completará su trazado mediante un nuevo tramo que partirá del embalse de Atazar, en el Lozoya, para unirse al actual en el depósito regulador de Torrelaguna. Su capacidad es de 16 m3/s; su longitud, 43,471 km, y su pendiente, 4 diezmilésimas. La sección tipo es análoga a la del canal del Jarama, de construcción anterior.

In the majority of BWS cases, HH will be transient; however, approximately in 5% of them, HH will be severe and often medically-unresponsive. Children with BWS due to paternal uniparental disomy (UPD) of chromosome 11p15 belong to this severe category and have traditionally required near-total pancreatectomy. The use of mTOR inhibitors had not been reported yet in this type of patients. A 1-month-old female with genetically confirmed BWS due to UPD of chromosome 11p15 was admitted for management of severe HH. Blood glucose concentrations were stabilised with high intravenous dextrose concentration, glucagon and octreotide infusions as she was proven to be diazoxide unresponsive. To avoid a subtotal pancreatectomy, an mTOR inhibitor - sirolimus - was introduced. The dose of sirolimus was optimised progressively and she was able to come off intravenous fluids and glucagon therapy. She has not presented any side effects and her growth is normal after 19 months of therapy. This is the first case reported of BWS due to UPD of chromosome 11p15 where sirolimus treatment has been effective in stabilising the blood glucose concentrations and avoiding a near-total pancreatectomy without major side effects detected. © 2016 S.

    Full Text Available Background: Treacher-Collins syndrome is a congenital craniofacial disorder with multiple anomalies. This syndrome affects the maxilla, mandible, eyes, middle and outer ears, and soft palate. Conductive hearing loss due to the deformities of the middle and external ears is prevalent. The characteristics of this syndrome include multiple and serious threats to normal communication development in children. In this study, speech and language features of a Persian speaking child with this syndrome are presented.Case: The case was an 8-year old girl with Treacher-Collins syndrome and bilateral moderate conductive hearing loss due to atretic canal. In language and speech assessments, moderate hypernasality, numerous compensatory errors and morphosyntactic deficits were observed. There were 13 phonemes that were incorrectly produced at least in one position. Besides, she used 22 types of phonological processes that were abnormal and disappear before the age of three in normal Persian speaking children.Conclusion: Moderate hearing loss, velopharyngeal incompetency, malocclusion and dental anomalies, attention deficit/hyperactivity disorder (ADHD and environmental factors resulted in severe speech and language disorders in this case. These disorders affected her academic performance as well. Moderate hypernasality, numerous compensatory errors, and excessive and abnormal use of phonological processes were not presented as prevalent characteristics of Treacher-Collins syndrome in other resources.

    Full Text Available Dermatophytes are agents of typically benign superficial infections. However, an increasing number of severe infections in immunocompromised hosts has been reported. We aimed to understand the factors underlying the existence of a cohort of patients presenting with chronic widespread dermatophytosis (CWD due to Trichophyton rubrum, but with no signs of immunodeficiency. Their disease is usually recurrent and difficult to manage. Fourteen patients meeting the following criteria for CWD were studied: T. rubrum culture-proven skin lesions of ≥10 cm in at least one dimension; the involvement of at least three noncontiguous localizations of >1 year’s duration; and no predisposing conditions. For comparison, we also studied 13 acute Tinea pedis patients. Macrophages and neutrophils were isolated and tested for T. rubrum conidia phagocytic and killing activity. H2O2, NO, and pro- and anti-inflammatory cytokine release were measured. All experiments were run with age- and sex-matched healthy donors’ cells in parallel. CWD patients’ macrophages and neutrophils presented with reduced T. rubrum–phagocytic and killing abilities, and reduced H2O2 and NO release when compared with those of healthy donors. CWD patients’ macrophages secreted lower levels of the proinflammatory cytokines interleukin (IL-1, IL-6, IL-8, and tumor necrosis factor (TNF-α, but enhanced levels of the anti-inflammatory cytokine IL-10. Neutrophil secretion closely followed this unbalanced pattern. In contrast, responses to the positive controls zymosan, lipopolysaccharide, and phorbol myristate acetate were comparable with those of healthy donors. The same experiments were performed with macrophages and neutrophils from the acute T. pedis patients and showed no differences when compared with the matched healthy donors. Patients with CWD have a T. rubrum-related functional deficiency of phagocytes and may represent a distinct clinical entity in the complex spectrum of the

    Francis, Brian A; Akil, Handan; Bert, Benjamin B

    2017-01-01

    In primary open-angle glaucoma, the site of greatest resistance to aqueous outflow is thought to be the trabecular meshwork (TM) and inner wall of Schlemm's canal. Augmentation of the conventional (trabecular) outflow pathway can facilitate physiologic outflow and subsequently lower intraocular pressure. The most recent approach to enhancing the conventional outflow pathway is via an internal approach to the TM and Schlemm's canal. Ab interno Schlemm's canal surgery includes 4 novel surgical approaches: (1) removal of the TM and inner wall of Schlemm's canal by an internal approach (ab interno trabeculectomy), (2) implantation of a microstent to bypass the TM, (3) disruption of the TM and inner wall of Schlemm's canal via an internal approach (ab interno trabeculotomy), and (4) dilation of Schlemm's canal via an internal approach (ab interno canaloplasty). The first category includes the Trabectome (Neomedix, Tustin, CA, USA), and Kahook Dual Blade (New World Medical, Rancho Cucamonga, CA, USA). The second category includes the iStent (Glaukos, Laguna Hills, CA, USA), as well as the investigational Hydrus Microstent implant (Ivantis, Irvine, CA, USA). The third category includes gonioscopic-assisted transluminal trabeculotomy (iSciences catheter; Ellex, Adelaide, Australia), and 360° suture trabeculotomy (TRAB360, Sight Sciences, Menlo Park, CA, USA). The fourth category includes ab interno canaloplasty or AbiC (Ellex), and Visco360 (Sight Sciences). In contrast to external filtration surgeries, such as trabeculectomy and aqueous tube shunt, these procedures are categorized as internal filtration surgeries and are performed from an internal approach via gonioscopic guidance. Published results suggest that these surgical procedures are both safe and efficacious for the treatment of open-angle glaucoma. © 2017 S. Karger AG, Basel.

    Root canal therapy (RCT) represents a standard of treatment that addresses infected pulp tissue in teeth and protects against future infection. RCT involves removing dental pulp comprising blood vessels and nerve tissue, decontaminating residually infected tissue through biomechanical instrumentation, and root canal obturation using a filler material to replace the space that was previously composed of dental pulp. Gutta percha (GP) is typically used as the filler material, as it is malleable, inert, and biocompatible. While filling the root canal space with GP is the standard of care for endodontic therapies, it has exhibited limitations including leakage, root canal reinfection, and poor mechanical properties. To address these challenges, clinicians have explored the use of alternative root filling materials other than GP. Among the classes of materials that are being explored as novel endodontic therapy platforms, nanodiamonds (NDs) may offer unique advantages due to their favorable properties, particularly for dental applications. These include versatile faceted surface chemistry, biocompatibility, and their role in improving mechanical properties, among others. This study developed a ND-embedded GP (NDGP) that was functionalized with amoxicillin, a broad-spectrum antibiotic commonly used for endodontic infection. Comprehensive materials characterization confirmed improved mechanical properties of NDGP over unmodified GP. In addition, digital radiography and microcomputed tomography imaging demonstrated that obturation of root canals with NDGP could be achieved using clinically relevant techniques. Furthermore, bacterial growth inhibition assays confirmed drug functionality of NDGP functionalized with amoxicillin. This study demonstrates a promising path toward NDGP implementation in future endodontic therapy for improved treatment outcomes.

    The hypothesis that somatotype and cervical spine developmental canal stenosis may be associated has been investigated by anthropometry and measurement of lateral projection cervical spine radiographs. A significant association of canal size with somatotype has been found such that those with developmentally narrow canals are more likely to have relatively shorter long-bones, particularly in the upper arm, and longer trunks.

    We assessed the value of MRI for delineation of dehiscence of the superior or posterior semicircular canal, as compared with CT, the current standard study for this entity. We reviewed heavily T2-weighted fast spin-echo images and high-resolution CT of the temporal bones of 185 patients independently semicircular canal dehiscence and its extent. In 30 patients (19 men, 11 women) we identified dehiscence of the bone over the superior and/or posterior semicircular canal on MRI. In 27 of these cases CT also showed circumscribed bone defects. In one patient dehiscence of the superior semicircular canal was initially overlooked on MRI, but seen on CT. MRI imaging thus had a sensitivity of 96% and specificity of 98%. Knowledge of the appearances of this entity on MRI may contribute to early diagnosis in patients with vertigo due to semicircular canal dehiscence. (orig.)

    Cervical spine manipulation (CSM) is a commonly spinal manipulative therapies for the relief of cervical spine-related conditions worldwide, but its use remains controversial. CSM may carry the potential for serious neurovascular complications, primarily due to vertebral artery dissection (VAD) and subsequent vertebrobasilar stroke. Here, we reported a rare case of locked-in syndrome (LIS) due to bilaterial VAD after CSM treated by arterial embolectomy.A 36-year-old right-handed man was admitted to our hospital with numbness and weakness of limbs after treating with CSM for neck for half an hour. Gradually, although the patient remained conscious, he could not speak but could communicate with the surrounding by blinking or moving his eyes, and turned to complete quadriplegia, complete facial and bulbar palsy, dyspnea at 4 hours after admission. He was diagnosed with LIS. Then, the patient was received cervical and brain computed tomography angiography that showed bilateral VAD. Aortocranial digital subtraction angiography showed vertebrobasilar thrombosis, blocking left vertebral artery, and stenosis of right vertebral artery. The patient was treated by using emergency arterial embolectomy and followed by antiplatelet therapy and supportive therapy in the intensive care unit and a general ward. Twenty-seven days later, the patient's physical function gradually improved and discharged but still left neurological deficit with muscle strength grade 3/5 and hyperreflexia of limbs.Our findings suggested that CSM might have potential severe side-effect like LIS due to bilaterial VAD, and arterial embolectomy is an important treatment choice. The practitioner must be aware of this complication and should give the patients informed consent to CSM, although not all stroke cases temporally related to SCM have pre-existing craniocervical artery dissection.

  5. FGFR2 exon IIIa and IIIc mutations in Crouzon, Jackson-Weiss, and Pfeiffer syndromes: Evidence for missense changes, insertions, and a deletion due to alternative RNA splicing

    Fibroblast growth factor receptor 2 (FGFR2) mutations have been associated with the craniosynostotic conditions Crouzon, Jackson-Weiss, and Pfeiffer syndromes. Previously, mutations were described in the exons IIIa and IIIc, which form the extracellular, third immunoglobulin-like domain (IgM) and adjacent linker regions, both of which are normally involved in ligand binding. For all three conditions, mutations were found in exon IIIc. Only in Crouzon syndrome were mutations identified in exon IIIa. In this study, 39 cases with one of these three conditions were screened for exon IIIa or IIIc mutations. Eleven mutations are reported in 17 unrelated cases. Mutations in exon IIIa are identified for not only Crouzon but also Jackson-Weiss and Pfeiffer syndromes. Four mutations in either exon IIIa or exon IIIc reported only in Crouzon syndrome are present also in one of the other two syndromes. Two insertions, one in exon IIIa in a Crouzon syndrome patient and the other in exon IIIc in a Pfeiffer syndrome patient, were observed. The latter mutation has the same alternative RNA splicing effect as a reported synonymous mutation for Crouzon syndrome. A missense mutation was detected in one Pfeiffer syndrome family in which two members had craniosynostosis without limb anomalies. The inter- and intrafamilial variability in expression of FGFR2 mutations suggests that these three syndromes, presumed to be clinically distinct, are instead representative of a spectrum of related craniosynostotic and digital disorders. 16 refs., 3 figs., 1 tab.

    Collapsed ear canals typically occur when an outside force, such as a headset for audiometric testing, is present. However, when a collapsed ear canal occurs without external pressure, this creates a challenge not only for performing audiometric testing but also for coupling a hearing aid to the ear canal. This case report highlights the challenges associated with fitting a hearing aid on a patient with a severe anterior-posterior collapsed ear canal with a mixed hearing loss. A 67-yr-old female originally presented to Washington University in St. Louis School of Medicine in 1996 with a long-standing history of bilateral otosclerosis. She had chronic ear infections in the right ear and a severely collapsed ear canal in the left ear and was fit with a bone anchored hearing aid (BAHA®) on the right side in 2003. However, benefit from the BAHA started to decrease due to changes in hearing, and a different hearing solution was needed. It was proposed that a hearing aid be fit to her collapsed left ear canal; however, trying to couple a hearing aid to the collapsed ear canal required unique noncustom earmold solutions. This case study highlights some of the obstacles and potential solutions for coupling a hearing aid to a severely collapsed ear canal. American Academy of Audiology.

    Among the temporal bone abnormalities that can be found in the etiological study of paediatric sensorineural hearing loss (SNHL) by imaging techniques, those related to the internal auditory canal (IAC) are the least frequent. The most prevalent of these abnormalities that is associated with SNHL is stenotic IAC due to its association with cochlear nerve deficiencies. Less frequent and less concomitant with SNHL is the finding of an enlarged IAC (>8mm). Retrospective and descriptive review of clinical associations, imaging, audiological patterns and treatment of 9 children with hearing loss and enlarged IAC in the period 1999 to 2012. Two groups of patients are described. The first, without association with vestibulocochlear dysplasias, consisted of: 2 patients with SNHL without other temporal bone or systemic abnormalities, one with bilateral mixed HL from chromosome 18q deletion, one with a genetic X-linked DFN3 hearing loss, one with unilateral hearing loss in neurofibromatosis type 2 with bilateral acoustic neuroma, and one with unilateral hearing loss with cochlear nerve deficiency. The second group, with association with vestibulocochlear dysplasias, was comprised of: one patient with moderate bilateral mixed hearing loss in branchio-oto-renal syndrome, one with profound unilateral SNHL with recurrent meningitis, and another with profound bilateral SNHL with congenital hypothyroidism. The presence of an enlarged IAC in children can be found in different clinical and audiological settings with relevancies that can range from life-threatening situations, such as recurrent meningitis, to isolated hearing loss with no other associations.

    2007-07-01

    Full Text Available Abstract Background: Autoimmune lymphoproliferative syndrome (ALPS is a disorder of lymphocyte homeostasis and immunological tolerance due primarily to genetic defects in Fas (CD95/APO-1; TNFRSF6, a cell surface receptor that regulates apoptosis and its signaling apparatus. Methods: Fas ligand gene mutations from ALPS patients were identified through cDNA and genomic DNA sequencing. Molecular and biochemical assessment of these mutant Fas ligand proteins were carried out by expressing the mutant FasL cDNA in mammalian cells and analysis its effects on Fas-mediated programmed cell death. Results: We found an ALPS patient that harbored a heterozygous A530G mutation in the FasL gene that replaced Arg with Gly at position 156 in the protein's extracellular Fas-binding region. This produced a dominant-interfering FasL protein that bound to the wild-type FasL protein and prevented it from effectively inducing apoptosis. Conclusion: Our data explain how a naturally occurring heterozygous human FasL mutation can dominantly interfere with normal FasL apoptotic function and lead to an ALPS phenotype, designated Type Ib.

    2018-01-01

    Full Text Available We present a case of a 52-year-old male who developed Cushing’s Syndrome due to ectopic adrenocorticotrophic hormone (ACTH secretion from a large esthesioneuroblastoma (ENB of the nasal sinuses. The patient initially presented with polyuria, polydipsia, weakness, and confusion. Computed tomography scan of the head and magnetic resonance imaging showed a 7 cm skull base mass centered in the right cribriform plate without sella involvement. Work-up revealed ACTH-dependent hypercortisolemia, which did not suppress appropriately after high-dose dexamethasone. Subsequent imaging of the chest, abdomen, and pelvis did not reveal other possible ectopic sources of ACTH secretion besides the ENB. His hospital course was complicated by severe hypokalemia and hyperglycemia before successful surgical resection of the tumor, the biopsy of which showed ENB. Postoperatively, his ACTH level dropped below the limit of detection. In the ensuing 4 months, he underwent adjuvant chemoradiation with carboplatin and docetaxel with good response and resolution of hypokalemia and hyperglycemia, with no sign of recurrence as of 30 months postoperatively. His endogenous cortisol production is rising but has not completely recovered.

    2013-01-01

    Full Text Available Juvenile primary hypothyroidism causing cystic ovaries and pseudoprecocious puberty (Van-Wyk Grumbach syndrome (VWGS is well documented in literature. There are only a few reports of primary hypothyroidism presenting as ovarian cysts in adults. Here we present a case of huge bilateral ovarian cysts in adulthood as the presenting feature of VWGS due to chronic uncontrolled juvenile hypothyroidism. Large uniloculor right ovarian cyst (119 × 81 × 90 mm and a multicystic left ovary (55 × 45 × 49 mm were detected in a 24 year lady with secondary amenorrhea, galactorrhea, and palpable abdominal mass with history of neonatal jaundice, delayed milestones, short stature, and precocious menarche at age of 7.5 years age. She had elevated levels of cancer antigen (CA-125 which normalized post levothyroxine supplementation. Elevated CA-125 may lead to misdiagnosis of ovarian carcinoma and inadvertent treatment. Bilateral ovarian cysts in adults are a rare presentation of juvenile hypothyroidism. It is necessary to screen for primary hypothyroidism in patients presenting with bilateral ovarian cysts to prevent unnecessary evaluation and treatment.

  12. Unique Preservation of Neural Cells in Hutchinson- Gilford Progeria Syndrome Is Due to the Expression of the Neural-Specific miR-9 MicroRNA

    Directory of Open Access Journals (Sweden)

    Xavier Nissan

    2012-07-01

    Full Text Available One puzzling observation in patients affected with Hutchinson-Gilford progeria syndrome (HGPS, who overall exhibit systemic and dramatic premature aging, is the absence of any conspicuous cognitive impairment. Recent studies based on induced pluripotent stem cells derived from HGPS patient cells have revealed a lack of expression in neural derivatives of lamin A, a major isoform of LMNA that is initially produced as a precursor called prelamin A. In HGPS, defective maturation of a mutated prelamin A induces the accumulation of toxic progerin in patient cells. Here, we show that a microRNA, miR-9, negatively controls lamin A and progerin expression in neural cells. This may bear major functional correlates, as alleviation of nuclear blebbing is observed in nonneural cells after miR-9 overexpression. Our results support the hypothesis, recently proposed from analyses in mice, that protection of neural cells from progerin accumulation in HGPS is due to the physiologically restricted expression of miR-9 to that cell lineage.

  13. A Hypothesis for the Cause of Complex Regional Pain Syndrome - Type I (Reflex Sympathetic Dystrophy): Pain Due to Deep-Tissue Microvascular Pathology

    Science.gov (United States)

    Coderre, Terence J.; Bennett, Gary J.

    2015-01-01

    Complex regional pain syndrome - type I (CRPS-I; Reflex Sympathetic Dystrophy) is a chronic pain condition that usually follows a deep-tissue injury such as fracture or sprain. The cause of the pain is unknown. We have developed an animal model (chronic post-ischemia pain; CPIP) that creates CRPS-I –like symptomology. The model is produced by occluding the blood flow to one hind paw for 3 hr under general anesthesia. Following reperfusion, the treated hind paw exhibits an initial phase of hyperemia and edema. This is followed by mechano-hyperalgesia, mechano-allodynia, and cold-allodynia that last for at least one month. Light- and electron microscopic analyses of the nerves at the site of the tourniquet show that the majority of these animals have no sign of injury to myelinated or unmyelinated axons. However, electron microscopy shows that the ischemia-reperfusion (I-R) injury produces a microvascular injury, slow-flow/no-reflow, in the capillaries of the hind paw muscle and digital nerves. We propose that the slow-flow/no-reflow phenomenon initiates and maintains deep tissue ischemia and inflammation, leading to the activation of muscle nociceptors, and the ectopic activation of sensory afferent axons due to endoneurial ischemia and inflammation. These data, and a large body of clinical evidence, suggest that in at least a subset of CRPS-I patients, the fundamental cause of the abnormal pain sensations is ischemia and inflammation due to microvascular pathology in deep tissues, leading to a combination of inflammatory and neuropathic pain processes. Moreover, we suggest a unifying idea that relates the pathogenesis of CRPS-I to that of CRPS-II. Lastly, our hypothesis suggests that the role of the sympathetic nervous system in CRPS-I is a factor that is not fundamentally causative, but may have an important contributory role in early stage disease.

    This paper presents an X-ray scheme for calculating the depth of pterygoid canals required for accurate tomography. The scheme includes three lines: line A corresponds to the physiological horizontal line, line B is drawn, normally to line A through the tip of the nose, and line C is the perpendicular from line B to the upper third of the posterior wall of the pterygopalatine fossa. The length of line B plus 1 cm (thickness of external nose soft tissues) is the value to be determined. Twenty-six patients underwent X-ray examinations by an EDK-750B unit (70 kV, 150 mA, 1.65 s). In all cases 1-3 images were sufficient to obtain good visualization of the pterygoid canals.

    To isolate and characterize bacteria and fungi from the healthy ear and to obtain susceptibility profiles on each bacterial isolate. Prospective. Specimens were collected from the external canals and cerumen of healthy subjects. Species-level identification was obtained by combining phenotypic and genotypic data. End-point minimal inhibitory concentration testing was performed using National Committee for Clinical Laboratory Standards recommended methods. One hundred sixty-four subjects were cultured. Seventeen canal and 16 cerumen specimens showed no growth. One hundred forty-eight cerumen specimens yielded 314 organisms, including 23 fungi. One hundred forty-seven canal specimens yielded 310 organisms, including 7 fungi. Of 291 bacteria isolated from cerumen, 99% were Gram-positive. Of 302 bacteria isolated from the canal, 96% were Gram-positive. Staphylococci were 63% of both the cerumen bacteria and the canal bacteria. Coryneforms represented 22% of the bacteria in cerumen and 19% in the canal. Turicellaotitidis was the primary coryneform isolated from both the canal and the cerumen. Streptococci-like bacteria were 10% from the cerumen, 7% from the canal. In both cerumen and canal, Alloiococcusotitis was more than 95% of the streptococci-like bacteria. Fifteen gram-negative organisms were isolated from the canal and cerumen, including four Pseudomonas aeruginosa strains. The percentages of Staphylococcus epidermidis isolates that had high-level resistance (> or =8 microg/mL) were as follows: to neomycin, 28% from cerumen and 11% from the canal; to oxacillin, 28% from cerumen and 25% from the canal; and to ofloxacin, 15% from cerumen and 19% from the canal. Turcellaotitidis and A. otitidis were present with a much higher frequency than previously described, lending evidence that they be considered normal otic flora. Corynebacterium auris, previously reported only in children, was isolated from normal adults.

    A large portion of the seismic noise spectrum is dominated by water wave energy coupled into the solid Earth. Distinct mechanisms of water wave induced ground motions are distinguished by their spectral content. For example, cultural noise is generally Panama Canal there is an additional source of long-period noise generated by standing water waves, seiches, induced by disturbances such as passing ships and wind pressure. We compare seismic waveforms to water level records and relate these observations to changes in local tilt and gravity due to an oscillating seiche. The methods and observations discussed in this paper provide a first step toward quantifying the impact of water inundation as recorded by seismometers. This type of quantified understanding of water inundation will help in future estimates of similar phenomena such as the seismic observations of tsunami impact.

    Full Text Available Antipsychotic and antidepressant are often used in combination for the treatment of neuropsychiatric disorders. The concomitant use of antipsychotic and/or antidepressant with drugs that may interact can lead to rare, life-threatening conditions such as serotonin syndrome and neuroleptic malignant syndrome. We describe a patient who has a history of taking two offending drugs that interact with drugs given during the course of hospital treatment which leads to the development of serotonin syndrome overlapped with neuroleptic malignant syndrome. The physician should be aware that both NMS and SS can appear as overlapping syndrome especially when patients use a combination of both antidepressants and antipsychotics.

    , or like talking in a barrel. This problem is caused by the occlusion effect. The effect is primarily due to vibrations of the walls in the soft part of the ear canal, which generate a sound pressure that is trapped in the cavity between the tip of the occluding hearing aid and the tympanic membrane....... If the hearing aid is fitted with a seal in the bony portion of the ear canal, preventing vibration in the soft part of the ear canal from reaching the tympanic membrane, then occlusion problems can be solved or at least reduced in most cases....

  5. HIGH RISK IN ROOT CANAL NEGOCIATION IN ELDERLY PATIENTS: CLINICAL CASE SERIES

    Directory of Open Access Journals (Sweden)

    Paula PERLEA

    2015-03-01

    Full Text Available Several clinical cases outline the difficulties of root canal treatment, due to the morphological changes of the endodontic space in elderly patients. The changes in the shape of pulp chamber and root canal make the treatment more difficult. It is also shown that the pulp chamber diminishes, due to reparative dentin. Calcification of the pulp space makes more difficult the access to the cavity. The obliterated canals lead to a challenging negotiation of the root canals. To avoid errors in the appreciation of the general health condition of the patient, the specialists should have an accurate preoperative radiograph or cone beam computing tomography (CBCT, use magnification (dental operative microscope, safe-ended burs, consider carefully any morphological changes, and apply the most proper techniques.

    variation and the canal's biological status were carried out. Velocity metering in the canal identified extremely low flow rates ~0.15m3s-1. A tracer testing procedure for the canal's low flow conditions was designed and implemented which identified a lack of rapid dispersion processes with D~0.133m3s-1. Water quality sampling consisted of a year-long programme of high frequency temporal and spatial sampling along the canal length. Observations demonstrate significant variability, with widely differing measurements of DO as little as 5m apart. In addition, spot samples of water quality taken from individual incoming field drains showed PO4-P concentrations up to 2mgl-1, with a predominance of nutrient bound clay and silt sediments that ultimately settle on the canal bed. Due to low dispersion rates, residence times for pollutants are long and field drains, in combination with navigational activity, may well be one of the primary causes of raised nutrient levels at some locations. This research has shown that canal water quality is highly spatially and temporally variable; far in excess of the variability normally found in river systems. This is mainly determined by a lack of hydraulic mixing and the presence of small quantities of incoming runoff water of very low quality. Whilst low in volume, incoming sediment from the drains appears to strongly influence the nearby canal water quality. These results have important consequences both for future monitoring strategies of canals and management of their gradual ecological improvement.

    Cri du chat syndrome is characterized by cat-like cry, facial dysmorphisms, microcephaly, speech delay, intellectual disability and slow growth rate, which are present with variable frequency. The typical cri du chat syndrome, due to 5p15.2 deletion, includes severe intellectual disability, facial dysmorphisms, neonatal hypotonia and pre- and post-natal growth retardation, whereas more distal deletions in 5p15.3 lead to cat-like cry and speech delay and produce the clinical picture of the atypical cri du chat syndrome, with minimal or absent intellectual impairment. In this article we report a three-generation family with an unbalanced whole arm translocation between chromosome 5 and 15 and a microdeletion of 5.5 Mb involving 5p15.33-32. By reporting the smallest terminal deletion of 5p15.3 described so far and by reviewing the literature we discuss the genotype/phenotype correlations of the distal region of the cri du chat syndrome. The previously described critical region for the speech delay may be narrowed down and microcephaly, growth retardation and dysmorphic facial features can be included in the phenotypic expression of the atypical cri du chat syndrome due to 5p15.3 deletions.

    The hypothesis that somatotype and cervical spine developmental canal stenosis may be associated has been investigated by anthropometry and measurement of lateral projection cervical spine radiographs. A significant association of canal size with somatotype has been found such that those with developmentally narrow canals are more likely to have relatively shorter long-bones, particularly in the upper arm, and longer trunks.

    Recent studies have suggested that disomic oocyte-mediated uniparental disomy 15 (UPD(15)mat) is increased in patients with Prader-Willi syndrome (PWS) born after medically assisted reproduction (MAR). However, it remains unknown whether the increase is primarily due to MAR procedure itself or advanced maternal childbearing ages as a predisposing factor for the disomic oocyte production. To examine this matter, we studied 122 naturally conceived PWS patients (PWS-NC group) and 13 MAR-conceived patients (PWS-MAR group). The relative frequency of disomic oocyte-mediated UPD(15)mat was significantly higher in PWS-MAR group than in PWS-NC group (7/13 vs 20/122, p = 0.0045), and the maternal childbearing ages were significantly higher in PWS-MAR group than in PWS-NC group [median (range), 38 (26-45) vs 30 (19-42), p = 0.0015]. However, the logistic regression analysis revealed no significant association between the occurrence of disomic oocyte-mediated UPD(15)mat and MAR, after adjusting for childbearing age (p = 0.25). Consistent with this, while the frequency of assisted reproductive technology (ART)-conceived livebirths was higher in the PWS patients than in the Japanese general population (6.4% vs 1.1%, p = 0.00018), the distribution of childbearing ages was significantly skewed to the increased ages in the PWS patients (p < 2.2 × 10(-16) ). These results argue against a positive association of MAR procedure itself with the development of UPD(15)mat. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2010-08-01

    Compression syndromes of the ulnar nerve are more often located proximally in the cubital tunnel than distally in Guyon's canal. In many cases anatomic structures can be found that induce compression. These may be ganglia, tumours, vascular abnormalities, crossing fibrous bands or accessory muscles. The ulnar nerve has therefore to be revised all along its passage through Guyon's canal. When other causes are excluded, it might be necessary to excise an accessory muscle to decompress the ulnar nerve sufficiently. Georg Thieme Verlag KG Stuttgart New York.

  13. Endodontic treatment of a C-shaped mandibular second premolar with four root canals and three apical foramina: a case report

    2016-02-01

    Full Text Available This case report describes a unique C-shaped mandibular second premolar with four canals and three apical foramina and its endodontic management with the aid of cone-beam computer tomography (CBCT. C-shaped root canal morphology with four canals was identified under a dental operating microscope. A CBCT scan was taken to evaluate the aberrant root canal anatomy and devise a better instrumentation strategy based on the anatomy. All canals were instrumented to have a 0.05 taper using 1.0 mm step-back filing with appropriate apical sizes determined from the CBCT scan images and filled using a warm vertical compaction technique. A C-shaped mandibular second premolar with multiple canals is an anatomically rare case for clinicians, yet its endodontic treatment may require a careful instrumentation strategy due to the difficulty in disinfecting the canals in the thin root area without compromising the root structure.

    Full Text Available Introduction: The aim of the study was to apply microcomputed tomography to quantitative evaluation of voids and to test any specific location of voids in tooth’s root canal obturations. Materials and Methods: Twenty root canals were prepared and obturated with gutta-percha and Tubli-Seal sealer using the thermoplastic compaction method (System B + Obtura II. Roots were scanned and three-dimensional visualization was obtained. The volume and Feret’s diameter of I-voids (at the filling/dentine interface and S-voids (surrounded by filling material were measured. Results: The results revealed that none of the scanned root canal fillings were void-free. For I-voids, the volume fraction was significantly larger, but their number was lower (P = 0.0007, than for S-voids. Both types of voids occurred in characteristic regions (P < 0.001. I-voids occurred mainly in the apical third, while S-voids in the coronal third of the canal filling. Conclusions: Within the limitations of this study, our results indicate that microtomography, with proposed semi-automatic algorithm, is a useful tools for three-dimensional quantitative evaluation of dental root canal fillings. In canals filled with thermoplastic gutta-percha and Tubli-Seal, voids at the interface between the filling and canal dentine deserve special attention due to of their periapical location, which might promote apical microleakage. Further studies might help to elucidate the clinical relevance of these results.

    Endoscopic procedures are becoming common in middle ear surgery. Inflammation due to chronic ear disease can cause bony erosion of the carotid artery and Fallopian canals, making them more vulnerable during surgery. The objective of this study was to determine whether or not chronic ear disease increases dehiscence of the carotid artery and Fallopian canals. Comparative human temporal bone study. Otopathology laboratory. We selected 78 temporal bones from 55 deceased donors with chronic otitis media or cholesteatoma and then compared those two groups with a control group of 27 temporal bones from 19 deceased donors with no middle ear disease. We analysed the middle ear, carotid artery canal and Fallopian canal, looking for signs of dehiscence of its bony coverage, using light microscopy. We found an increased incidence in dehiscence of the carotid artery and Fallopian canals in temporal bones with chronic middle ear disease. The size of the carotid artery canal dehiscence was larger in the middle ear-diseased groups, and its bony coverage, when present, was also thinner compared to the control group. Dehiscence of the carotid artery canal was more frequently located closer to the promontory. The incidence of Fallopian canal dehiscence was significantly higher in temporal bones from donors older than 18 years with chronic middle ear disease. The increased incidence of the carotid artery and Fallopian canal dehiscence in temporal bones with chronic middle ear disease elevates the risk of adverse events during middle ear surgery. © 2016 John Wiley & Sons Ltd.

  17. Nanodiamond–Gutta Percha Composite Biomaterials for Root Canal Therapy

    Science.gov (United States)

    2015-01-01

    Root canal therapy (RCT) represents a standard of treatment that addresses infected pulp tissue in teeth and protects against future infection. RCT involves removing dental pulp comprising blood vessels and nerve tissue, decontaminating residually infected tissue through biomechanical instrumentation, and root canal obturation using a filler material to replace the space that was previously composed of dental pulp. Gutta percha (GP) is typically used as the filler material, as it is malleable, inert, and biocompatible. While filling the root canal space with GP is the standard of care for endodontic therapies, it has exhibited limitations including leakage, root canal reinfection, and poor mechanical properties. To address these challenges, clinicians have explored the use of alternative root filling materials other than GP. Among the classes of materials that are being explored as novel endodontic therapy platforms, nanodiamonds (NDs) may offer unique advantages due to their favorable properties, particularly for dental applications. These include versatile faceted surface chemistry, biocompatibility, and their role in improving mechanical properties, among others. This study developed a ND-embedded GP (NDGP) that was functionalized with amoxicillin, a broad-spectrum antibiotic commonly used for endodontic infection. Comprehensive materials characterization confirmed improved mechanical properties of NDGP over unmodified GP. In addition, digital radiography and microcomputed tomography imaging demonstrated that obturation of root canals with NDGP could be achieved using clinically relevant techniques. Furthermore, bacterial growth inhibition assays confirmed drug functionality of NDGP functionalized with amoxicillin. This study demonstrates a promising path toward NDGP implementation in future endodontic therapy for improved treatment outcomes. PMID:26452304

  18. Conventional Versus Digital Radiography in Detecting Root Canal Type in Maxillary Premolars: An in Vitro Study

    2013-01-01

    Full Text Available Objective: Successful endodontic therapy depends on adequate mechanical and chemical debridement of the canal which requires knowledge of the canal morphology. Conventional radiography has been used to evaluate the canal type; however, direct digital radiography has recently been practiced for this purpose due to the shortcomings of conventional radiography. The aim of the present study was to compare the accuracy of digital and conventional radiography taken at 0° and 30° angles in the diagnosis of the canal type of extracted maxillary premolars.Materials and Methods: This diagnostic study was performed on 90 extracted maxillary premolars. Conventional and digital radiographies were taken of all teeth at 0° and 30° horizontal angles. The images were assessed by an oral and maxillofacial radiologist. The clearing technique was used as the gold standard. The canal type was determined using Weine classification. The agreement between each one of the 4 radiographic modalities and gold standard was determined by kappa statistics.Results: The kappa values for the agreement of parallel conventional, 30° conventional, parallel digital and 30° digital modalities with the clearing technique were 0.059, 0.215, 0.043 and 0.391, respectively. Parallel modalities were unable to determine the tooth canal type. Radiographic images taken at 30° significantly determined the canal type, although only a poor level of agreement was noted between the two modalities and the clearing technique.Conclusion: All modalities had limited value to determine the root canal type in maxillary premolars. However, direct digital imaging taken at 30° angle showed the highest accuracy for canal type assessment.

    It is difficult to summarize an article of this type, in which the author is certain that his case has been presented fairly, but is aware that other views that are contrary could be stated and endorsed by pertinent clinical cases. Bearing this fact in mind, I wish to reiterate the following: Lateral canals are demonstrated in endodontic cases with much less frequency than they exist. This variance rarely, if ever, causes an endodontic failure. Some demonstrated lateral canals may really be other conditions. Preoperative evaluation should include examination of radiographs for lateral, as well as periapical, lesions. Lateral canals may be demonstrated by a variety of filling techniques. Careful canal preparation may enhance the frequency of such demonstration. Cases with necrotic pulps probably yield more frequent demonstration than do cases with vital pulps. Lateral canals harboring inflamed and/or infected material may cause pain during endodontic treatment. They may simulate periodontal disease and may cause problems with treatment if present when a tooth is left open for drainage. Periodontal disease may cause pulp exposure via lateral canals located coronally. Improper use of post room may lead to lateral failure from breakdown of tissue in a lateral canal. The enigma of the lateral canal has been the object of description and discussion in many articles, but no one is truly certain of their exact significance in endodontic therapy for the long haul.

    The purpose of this study was to assess computed tomography (CT) findings of mandibular nutrient canals using CT images. We retrospectively analyzed the mandibular CT images of 194 consecutive patients. For image analysis such as canal prevalence, location, number, size, shape, and the CT value of nutrient foramina were determined using CT axial images of 0.5 and 3 mm slice thickness. We revealed that the nutrient canals were seen 94.3% in the mandible, mostly seen in the anterior region. By location, nutrient canals were particularly seen between the central and lateral incisors. The mean number of nutrient canals was 2.7. The mean diameter of the nutrient foramen between the central and lateral incisors was 1.0 mm. In about 80% of the cases, foramina between the central and lateral incisors were ovoid. The mean CT value for the nutrient foramina between the central and lateral incisors was 411 HU. Mandibular nutrient canals were ovoid shape, and the mean CT value was 411 HU. By preoperative knowledge of the position and anatomy of the mandibular nutrient canals, complications such as injury to the nutrient canals can be avoided.

    Full Text Available Abstract Introduction Lemierre's syndrome is septic thrombophlebitis of the internal jugular vein leading to metastatic septic complications following an oropharyngeal infection. It is usually caused by the anaerobe, Fusobacterium necrophorum. Of late, meticillin-resistant Staphylococcus aureus is increasingly being recognised as a cause of community-acquired skin and soft tissue infections. We report a rare case of Lemierre's syndrome caused by community-acquired meticillin-resistant Staphylococcus aureus infection. Case presentation A previously healthy 16-year-old girl presented with fever of 13 days duration, painful swelling around the right eye and diplopia followed by the appearance of pulmonary infiltrates. Imaging studies confirmed the clinical suspicion of bilateral jugular venous thrombosis with septic pulmonary embolism. Meticillin-resistant Staphylococcus aureus was isolated on blood cultures. The hospital course was complicated by massive haemoptysis and pulmonary aspiration necessitating mechanical ventilation. The patient subsequently made a complete recovery. Conclusion Lemierre's syndrome, although rare, is a potentially lethal but treatable complication of head and neck sepsis. Early clinical recognition of Lemierre's syndrome and appropriate antibiotic treatment can be life-saving. One should consider the possibility of community-acquired meticillin-resistant Staphylococcus aureus infection in patients with suspected Lemierre's syndrome.

  6. Type III apical transportation of root canal

    2012-01-01

    Full Text Available Procedural accidents leading to complications such as canal transportation have been ascribed to inapt cleaning and shaping concepts. Canal transportation is an undesirable deviation from the natural canal path. Herewith a case of apical transportation of root canal resulting in endodontic retreatment failure and its management is presented. A healthy 21-year-old young male presented discomfort and swelling associated with painful endodontically retreated maxillary incisor. Radiograph revealed periradicular radiolucency involving underfilled 11 and overfilled 12. Insufficiently obturated 11 exhibited apical transportation of canal. This type III transportation was treated by periradicular surgery and repair using white mineral trioxide aggregate (MTA. Comfortable asymptomatic patient presented uneventful healing at third and fourth month recall visits. A decrease in the size of radiolucency in radiograph supported the clinical finding. In the present case, MTA is useful in repairing the transportation defect. The result of these procedures is predictable and successful.

  7. Updated regime equations for alluvial Egyptian canals

    2016-03-01

    Full Text Available Real accuracy of several regime relationships for designing stable alluvial channels in Egypt was determined. Extensive field measurements had been carried out on 26 Egyptian stable canals, which cover various categories of irrigation canals starting from distributary, branch to carrier canals in Egypt. Analysis of 1484 velocity profiles for 371 cross sections was employed in order to formulate new regime equations characterizing Egyptian canals. The functional formulations to include the flow depth, cross section area, hydraulic radius and mean velocity were achieved. This research compared the deduced formulas from the measured data with the equations derived by other researchers for stable channel design. It was found that the derived formulas are reliable and could help in the design of Egyptian canals to convey a discharge ranging from 0.11 to 287.5 m3/s (0.0095–24.84 millions m3/day.

    Heimler syndrome (HS) is a rare recessive disorder characterized by sensorineural hearing loss (SNHL), amelogenesis imperfecta, nail abnormalities, and occasional or late-onset retinal pigmentation. It is the mildest form known to date of peroxisome biogenesis disorder caused by hypomorphic mutations of PEX1 and PEX6 genes. We report on a second Moroccan family with Heimler syndrome with early onset, severe visual impairment and important phenotypic overlap with Usher syndrome. The patient carried a novel homozygous missense variant c.3140T > C (p.Leu1047Pro) of PEX1 gene. As standard biochemical screening of blood for evidence of a peroxisomal disorder did not provide a diagnosis in the individuals with HS, patients with SNHL and retinal pigmentation should have mutation analysis of PEX1 and PEX6 genes.

    2013-03-01

    Full Text Available The so-called papular-purpuric gloves and socks syndrome (PPGSS is a condition characterized by acute onset of intense erythema, edema and petechiae with a typical localization on the hands and feet, besides mucosal lesions of the oral cavity. The syndrome has a favorable and self-limited course, requiring only a symptomatic therapy. In the 50% of the cases described in literature (ninety cases in 22 years, is documented an acute infection caused by parvovirus B19 and in only two cases the onset of PPGSS is reported among different members of the same family. The aim of the work is to describe two cases of PPGSS arisen during a short time period in two family members affected by an acute parvovirus B19 infection found by serum sampling. The peculiarity of the study was the infrequence of the syndrome and the rareness of the description of PPGSS in rheumatology. This syndrome is usually described in dermatology, but it is also interesting for the rheumatologist because it comes in differential diagnosis with various autoimmune diseases.

    The comprehensive environmental study which describes the results of a monitoring program conducted by EPA at Love Canal is evaluated by EPA's former study director. Attention is focused on the episode's history and the agency's study methods. The aim of the program was to constitute a study team, design a monitoring study, reprogram and reallocate the financial resources needed to conduct the study, and identify and employ contractors who would collect and analyze environmental samples. The agency was directed to ensure the quality of the data acquired from various environmental media and analyzed by numerous laboratories; to integrate, interpret, and report the data; and to assess, from an environmental perspective, the habitability of the area.

  16. Value of syndromic surveillance in monitoring a focal waterborne outbreak due to an unusual Cryptosporidium genotype in Northamptonshire, United Kingdom, June - July 2008.

    The United Kingdom (UK) has several national syndromic surveillance systems. The Health Protection Agency (HPA)/NHS Direct syndromic surveillance system uses pre-diagnostic syndromic data from a national telephone helpline, while the HPA/QSurveillance national surveillance system uses clinical diagnosis data extracted from general practitioner (GP)-based clinical information systems. Data from both of these systems were used to monitor a local outbreak of cryptosporidiosis that occurred following Cryptosporidium oocyst contamination of drinking water supplied from the Pitsford Reservoir in Northamptonshire, United Kingdom, in June 2008. There was a peak in the number of calls to NHS Direct concerning diarrhoea that coincided with the incident. QSurveillance data for the local areas affected by the outbreak showed a significant increase in GP consultations for diarrhoea and gastroenteritis in the week of the incident but there was no increase in consultations for vomiting. A total of 33 clinical cases of cryptosporidiosis were identified in the outbreak investigation, of which 23 were confirmed as infected with the outbreak strain. However, QSurveillance data suggest that there were an estimated 422 excess diarrhoea cases during the outbreak, an increase of about 25% over baseline weekly levels. To our knowledge, this is the first time that data from a syndromic surveillance system, the HPA/QSurveillance national surveillance system, have been able to show the extent of such a small outbreak at a local level. QSurveillance, which covers about 38% of the UK population, is currently the only GP database that is able to provide data at local health district (primary care trust) level. The Cryptosporidium contamination incident described demonstrates the potential usefulness of this information, as it is unusual for syndromic surveillance systems to be able to help monitor such a small-scale outbreak.

    The semicircular canals are biomechanical sensors responsible for detecting and encoding angular motion of the head in 3D space. Canal afferent neurons provide essential inputs to neural circuits responsible for representation of self-position/orientation in space, and to compensatory circuits including the vestibulo-ocular and vestibulo-collic reflex arcs. In this work we derive, to our knowledge, a new 1D mathematical model quantifying canal biomechanics based on the morphology, dynamics of the inner ear fluids, and membranous labyrinth deformability. The model takes the form of a dispersive wave equation and predicts canal responses to angular motion, sound, and mechanical stimulation. Numerical simulations were carried out for the morphology of the human lateral canal using known physical properties of the endolymph and perilymph in three diverse conditions: surgical plugging, rotation, and mechanical indentation. The model reproduces frequency-dependent attenuation and phase shift in cases of canal plugging. During rotation, duct deformability extends the frequency bandwidth and enhances the high frequency gain. Mechanical indentation of the membranous duct at high frequencies evokes traveling waves that move away from the location of indentation and at low frequencies compels endolymph displacement along the canal. These results demonstrate the importance of the conformal perilymph-filled bony labyrinth to pressure changes and to high frequency sound and vibration. Published by Elsevier Inc.

    The Agua Salud Project utilizes the Panama Canal’s (Canal) central role in world commerce to focus global attention on the ecosystem services provided by tropical forests. The Canal was one of the great engineering projects in the world. Completed in 1914, after almost a decade of concerted effort, its 80 km length greatly shortened the voyage between the Atlantic and Pacific Oceans. An entire class of ships, the Panamax, has been constructed to maximize the amount of cargo that can be carried in a Canal passage. In today’s parlance, the Canal is a “green” operation, powered largely by water (Table 1). The locks, three pairs on each end with a net lift of 27 meters, are gravity fed. For each ton of cargo that is transferred from ocean to ocean, about 13 tons of water (m3) are used. Lake Gatún forms much of the waterway in the Canal transect. Hydroelectricity is generated at the Gatún dam, whenever there is surplus water, and at Madden Dam (completed in 1936) when water is transferred from Lake Alhajuela to Lake Gatún. The Canal watershed is the source of drinking water for Panama City and Colon City, at either end of the Canal, and numerous towns in between.

    Full Text Available Enlargement of the mandibular canal is a rare radiological finding. Clinically, it may or may not be associated with sensory deficits. We report four cases of widening of the mandibular canal observed with various methods of imaging with different clinical characteristics. We describe this unique radiological finding and elaborate the importance of quality assessment of the imaging that is vital for accurate diagnosis and treatment planning. Clinicians should be mindful when assessing the imaging whenever the size of the mandibular canal is implicated. The case ranged from a benign tumor to malignancy, radiological errors, and artifacts. A more superior imaging or treatment modality was necessary to ascertain the diagnosis.

    Congenital myasthenic syndromes are inherited disorders caused by various defects in neuromuscular transmission. Although the typical presentation is fatigable weakness with prominent cranial involvement, neonates can lack these hallmark manifestations, and in those with choline acetyltransferase gene mutations, basal electrophysiological testing can yield negative findings. The authors report the case of a male infant presenting at birth with oculomotor and bulbofacial weakness, hypotonia, clubfoot, and severe respiratory insufficiency. Electromyography showed myogenic signs, and basal repetitive nerve stimulation yielded negative findings. Since age 6 months, the infant had progressively improved, acquiring autonomous respiration. Prolonged subtetanic repetitive nerve stimulation disclosed a marked decremental response compatible with suspected congenital myasthenic syndrome with episodic apnea. Genetic testing identified 2 novel choline acetyltransferase mutations (R470X, F580C). Keeping a high clinical suspicion of this rare condition and undertaking early comprehensive electrophysiological assessments including prolonged repetitive nerve stimulation (10 Hz for 5 minutes) can expedite the diagnosis.

    Leigh syndrome (LS), or subacute necrotizing encephalomyelopathy, is a genetically heterogeneous, relentlessly progressive, devastating neurodegenerative disorder that usually presents in infancy or early childhood. A diagnosis of Leigh-like syndrome may be considered in individuals who do not fulfil the stringent diagnostic criteria but have features resembling Leigh syndrome.We describe a unique presentation of Leigh-like syndrome in a 3-year-old boy with elevated 3-hydroxyisovalerylcarnitine (C5-OH) on newborn screening (NBS). Subsequent persistent plasma elevations of C5-OH and propionylcarnitine (C3) as well as fluctuating urinary markers were suggestive of multiple carboxylase deficiency (MCD). Normal enzymology and mutational analysis of genes encoding holocarboxylase synthetase (HLCS) and biotinidase (BTD) excluded MCD. Biotin uptake studies were normal excluding biotin transporter deficiency. His clinical features at 13 months of age comprised psychomotor delay, central hypotonia, myopathy, failure to thrive, hypocitrullinemia, recurrent episodes of decompensation with metabolic keto-lactic acidosis and an episode of hyperammonemia. Biotin treatment from 13 months of age was associated with increased patient activity, alertness, and attainment of new developmental milestones, despite lack of biochemical improvements. Whole exome sequencing (WES) analysis failed to identify any other variants which could likely contribute to the observed phenotype, apart from the homoplasmic (100%) m.8993T>G variant initially detected by mitochondrial DNA (mtDNA) sequencing.Hypocitrullinemia has been reported in patients with the m.8993T>G variant and other mitochondrial disorders. However, persistent plasma elevations of C3 and C5-OH have previously only been reported in one other patient with this homoplasmic mutation. We suggest considering the m.8993T>G variant early in the diagnostic evaluation of MCD-like biochemical disturbances, particularly when associated with

    Since 1983, we have performed 434 spinal surgery operations. Among them are included 51 cases of lumbar canal stenosis. For these 51 cases, we performed several neuroradiological examinations, such as lumbar plain X-ray, myelography, metrizamide-CT scan (Met-CT) and magnetic resonance imaging (MRI). On myelography, these 51 patients were divided into three types; a complete block type with 29 patients, soy-beans type with 7 patients and strangulation type with 15 patients. Met CT was performed in 37 cases. In both strangulation type and soy-beans type which had been showed through myelography, Met-CT could clearly demonstrate the subarachnoid space, and several structures around the lumbar spinal canal could be clearly identified. In cases which myelography revealed as complete-block type, we identified two subtypes. In the first type subarachnoid space was clearly demonstrated by Met-CT. The second type was comprised of those cases where Met-CT scan could not demonstrate subarachnoid space at all. MRI was performed on 21 patients. MRI clearly showed the anatomical relationship of disc, subarachnoid space, yellow ligament and hypertrophied bony structure. MRI was thus able to bring useful information about lumbar canal stenosis even in cases where Met-CT gave little information due to the lack of metrizamide penetration of the stenotic subarachnoid space.

    2010-01-01

    Full Text Available Introduction. Root canal preparation is the most important phase of endodontic procedure and it consists of adequate canal space cleaning and shaping. In recent years, rotary instruments and techniques have gained importance because of the great efficacy, speed and safety of the preparation procedure. Objective. The aim of this research was to investigate the influence of different NiTi files on the canal wall cleaning quality, residual dentine debris and smear layer. Methods. The research was conducted on extracted human teeth in vitro conditions. Teeth were divided in 7 main groups depending on the kind of instruments used for root canal preparation: ProTaper, GT, ProFile, K-3, FlexMaster, hand ProTaper and hand GT. Root canal preparation was accomplished by crown-down technique. Prepared samples were assessed on scanning electron microscopy JEOL, JSM-6460 LV. The evaluation of dentine debris was done with 500x magnification, and the evaluation of smear layer with 1,000 times magnification. Quantitive assessment of dentine debris and smear layer was done according to the criteria of Hulsmann. Results. The least amount of debris and smear layer has been found in canals shaped with ProFile instruments, and the largest amount in canals shaped with FlexMaster instruments. Canal cleaning efficacy of hand GT and ProTaper files has been similar to cleaning efficacy of rotary NiTi files. Statistic analysis has shown a significant difference in amount of dentine debris and smear layer on the canal walls between sample groups shaped with different instruments. Conclusion. Completely clean canals have not been found in any tested group of instruments. The largest amount of debris and smear layer has been found in the apical third of all canals. The design and the type of endodontic instruments influence the efficacy of the canal cleaning.

    The aim was to determine the success rate of single visit root canal treatment (RCT) and thus encourage clinicians to offer this treatment option appropriately. This was a longitudinal clinical study involving all teeth of the secondary dentition except third molars in the upper and lower jaws. Teeth having irreversible pulpitis, pulp necrosis or periapical periodontitis were included in the study. RCT and obturation was done at a single visit. The patients were monitored over 6 months. Forty-five teeth were treated in 21 females and 24 males, aged 18-56 years (34.4+/-12.7). Preoperatively, pain was present in 84.4%, tenderness to percussion in 53.3%, and periapical radiolucency in 24.4% teeth. Forty percent had irreversible pulpitis and 60% had apical periodontitis. Post-operatively, pain reduced to 51.1% on day 1, 15.5% at 1 week, and 0% for the rest of the period. Tenderness to percussion reduced to 15.6% at 1 week and 0% by 1 month. Periapical radiolucency reduced to 9.5% at 6 months. Favorable outcome of 33.3% was recorded on day 1 and increased to 90.5% at 6 months. Six months success rate for teeth which had irreversible pulpitis was 100% and 83.3% for apical periodontitis. The mean time needed to complete a single visit RCT ranged from 77 min for a tooth having one canal to 132 min for one having four canals. Single visit RCT is a viable treatment option for teeth having irreversible pulpitis or apical periodontitis irrespective of tooth type or number of canals. A lot of patients are lost to follow-up visits for teeth requiring RCT once the pulp is extirpated at the first visit due to cessation of pain, subsequently leading to treatment failure. Single visit endodontics eliminates the need for follow-up visits and improves treatment prognosis.

    To investigate the vertical and horizontal distribution and the incidence of accessory canals in Japanese maxillary anterior teeth following root filling. The study included maxillary teeth; 69 central incisors, 61 lateral incisors and 31 canines. After the canal systems had been dyed and root canal instrumentation had been carried out, all prepared canals were filled with gutta-percha without using sealer. Transparent specimens were then obtained and examined with a digital microscope for horizontal and vertical distributions of accessory canals. The incidence of teeth with accessory canals in the apical 3 mm was 46%, 29% and 38% for the maxillary central incisors, lateral incisors and canines, respectively. The horizontal distribution was mainly buccal for central incisors, palatal for lateral incisors and distal and palatal for canines. There was a significant difference (P < 0.05) between the apical 3 mm and the rest of the root (16%, 20% and 19% for the maxillary central incisors, lateral incisors and canines, respectively) in terms of the presence of accessory canals. A high percentage of accessory canals can be found in apical 3 mm of the root. The horizontal distribution of accessory canals differed amongst the tooth types studied.

    This in vitro study compared debridement efficacies of a sonic irrigation technique (Vibringe; Cavex Holland BV, Haarlem, The Netherlands) with side-vented needle irrigation (SNI) in the mesiobuccal root of maxillary first molars. Twenty roots with narrow isthmuses (≤ 1/4 canal diameter) were selected using micro-computed tomography scanning. Collagen solution was injected into canals/isthmuses and reconstituted with NH(4)OH to simulate canal debris. Each root was sealed apically and embedded in polyvinyl siloxane simulating a closed-canal system. Canals were instrumented to size 40/.04 taper 1 mm short of the anatomic apex. The final irrigation was performed with the Vibringe or SNI. Roots were demineralized, sectioned at 6 levels (1.2-3.2 mm) from the anatomic apex, and stained using Masson trichrome stain. The areas occupied by canals and isthmus and the debris-containing areas were statistically analyzed with repeated-measures analyses using "irrigation technique" as the between factor and "canal level" as the within factor (α = 0.05). Canals had significantly more debris at 1.2 and 1.6 mm (P .05). Considerably more debris remained at 1.2 and 2.0 mm for the Vibringe (P < .05). A significant difference was observed between the canal and the isthmus (P < .001). There is no difference between the Vibringe and SNI in their overall debridement efficacy in apical one third of the mesiobuccal root of maxillary first molars. Published by Elsevier Inc.

    The human vestibular system is a sensory and equilibrium system that manages and controls the human sense of balance and movement. It is the main sensor humans use to perceive rotational and linear motions. Determining an accurate mathematical model of the human vestibular system is significant for research pertaining to motion perception, as the quality and effectiveness of the motion cueing algorithm (MCA) directly depends on the mathematical model used in its design. This paper describes the history and analyses the development process of mathematical semicircular canal models. The aim of this review is to determine the most consistent and reliable mathematical semicircular canal models that agree with experimental results and theoretical analyses, and offer reliable approximations for the semicircular canal functions based on the existing studies. Selecting and formulating accurate mathematical models of semicircular canals are essential for implementation into the MCA and for ensuring effective human motion perception modeling.

    Recent studies indicate that the traditional Japanese herbal medicine yi-gan san (YGS, yokukan-san in Japanese) may be safe and useful for treating behavioral and psychological symptoms in dementia, borderline personality disorder, neuroleptic-induced tardive dyskinesia, and treatment-resistant schizophrenia. Visual hallucinations are common and often distressing consequences of vision loss, particularly in age-related macular degeneration. Charles Bonnet syndrome (CBS) is defined by the triad of complex visual hallucinations, ocular pathology causing visual deterioration, and preserved cognitive status. We aimed at evaluating both the efficacy and safety of YGS in patients with CBS. Twenty patients diagnosed with CBS were investigated, according to the diagnostic criteria established by Gold and Rabins and Teunisse. Participants were treated in a 4-week open-label study with YGS at an average daily dose of 5.8 ± 2.6 g (2.5-7.5 g). Psychometric instruments used to assess efficacy included the Neuropsychiatric Inventory, hallucination subscale of the Positive and Negative Syndrome Scale, and Clinical Global Impression. No cases of serious adverse events were attributed to the study's drug therapy. A significant decrease in visual hallucination was observed at 2 and 4 weeks in the Neuropsychiatric Inventory, hallucination subscale of the Positive and Negative Syndrome Scale, and Clinical Global Impression scores. Yi-gan san may be an effective and safe therapy to control visual hallucination in patients with CBS and should be further tested in double-blind, placebo-controlled trials. Given the design characteristics of this trial, the present findings should be taken cautiously.

    Silver-Russell syndrome (SRS) is a clinically and genetically heterogeneous syndrome characterized by severe intrauterine and postnatal growth retardation, facial dysmorphism and body asymmetry. One of the main molecular mechanisms leading to the syndrome involves methylation abnormalities of chromosome 11p15. In the last decades, an increase of imprinting disorders have been reported in children born from assisted reproductive technology (ART); however there is currently little evidence linking SRS and ART. Only few infants with SRS born using ART, supported by molecular analysis, have been described. We report on a twin-girl conceived using intracytoplasmic sperm injection (ICSI) diagnosed with SRS. Molecular studies revealed a hypomethylation of the paternal H19/IGF2 Imprinting Control Region. Her twin sister had a normal prenatal and postnatal growth and a normal methylation pattern of the chromosome 11p15. This is the second reported case of a twin infant with SRS conceived using ART with hypomethylation of H19/IGF2; it provides additional evidence of a possible relationship between ART procedures and methylation defects observed in SRS. Given the clinical heterogeneity of SRS, and the increased risk of multiple and preterm births in the ART-conceived children, it is possible that a number of cases of SRS remains undiagnosed in this population. Future studies should investigate the possible link between ART and SRS, in order to better understand the causes of epimutations in ART pregnancies, and to help clinicians to adequately counsel parents who approach to ART and to assess the opportunity of a long-term follow-up of children conceived using ART.

    Full Text Available Abstract Background Drug-Induced Hypersensitivity Syndrome (DIHS is a severe and rare systemic reaction triggered by a drug (usually an antiepileptic drug. We present a case of DISH and we review studies on the clinical features and treatment of DIHS, and on its pathogenesis in which two elements (Herpesvirus infection and the drug interact with the immune system to trigger such a syndrome that can lead to death in about 20% of cases. Case presentation We report the case of a 26-year old woman with fever, systemic maculopapular rash, lymphadenopathy, hepatitis and eosinophilic leukocytosis. She had been treated with antibiotics that gave no benefit. She was taking escitalopram and lamotrigine for a bipolar disease 30 days before fever onset. Because the patient's general condition deteriorated, betamethasone and acyclovir were started. This treatment resulted in a mild improvement of symptoms. Steroids were rapidly tapered and this was followed with a relapse of fever and a worsening of laboratory parameters. Human herpesvirus 6 (HHV-6 DNA was positive as shown by PCR. Drug-Induced Hypersensitivity Syndrome (DIHS was diagnosed. Symptoms regressed on prednisone (at a dose of 50 mg/die that was tapered very slowly. The patient recovered completely. Conclusions The search for rare causes of fever led to complete resolution of a very difficult case. As DIHS is a rare disease the most relevant issue is to suspect and include it in differential diagnosis of fevers of unknown origin. Once diagnosed, the therapy is easy (steroidal administration and often successful. However our case strongly confirms that attention should be paid on the steroidal tapering that should be very slow to avoid a relapse.

    Hajdu-Cheney syndrome (HCS) is a rare disorder principally characterized by acro-osteolysis, distinctive craniofacial and skull changes, dental anomalies and short stature. A common finding in HCS patients is secondary osteoporosis that progresses over time and contributes to various skeletal problems, especially fractures. Although autosomal dominant inheritance has been documented in several families, sporadic (non-familial) cases have also been reported. Here, a case of a 9-year-old girl with familial HCS and multiple spinal fractures, who has been effectively treated with pamidronate, is presented. This is the first report of a beneficial effect of intravenous bisphosphonate administration on a child with HCS-related osteoporosis.

    Full Text Available Spontaneous rapture with consequent retroperitoneal hemorrhage (Wunderlich’s syndrome is the complication mostly feared from large renal angiomyolipomas (RAMLs. In hemodynamic stable patients, minimal invasive therapies have superseded open surgery as the mainstay of treatment, with contemporary cases mostly treated by selective arterial embolization. Robotic-assisted laparoscopic partial nephrectomy (RALPN is an established minimal access treatment that has been used in the past for benign and malignant lesions of the kidney in the elective setting, but rarely in urgent situations as primary treatment. We present a case of a ruptured RAML in a young female treated effectively by RALPN.

    Full Text Available Antiglomerular basement membrane antibody disease is manifested by progressive glomerulonephritis, intraalveolar hemorrhage and antiglomerular basement membrane antibodies. It is frequently characterized by mortality. We present a case of a 18 year-old  young showing remission by early diagnosis. The patient was admitted to emergency department with symptoms and findings of atypic pneumonia with bloody sputum. Chest radiography detected patchy alveolar opacities (Figure A. An ampric antibacterial treatment was given including macrolide, and bronchodilators because of bronchospasm. The patient was suspected for goodpasture’s syndrome (GPS. Anti-glomerular basement membrane (AGBM antibodies test was send. He developed massive alveolar haemorrhage in the resolution phase of atypic pneumonia. Laboratory examination revealed proteinuria of 20 mg/ dl, anemia Hb of 8 g/dl, hematocrit of 25%, microscopic hematuria of 350 erythrocite /HPF. AGBM antibodies was found as positive. GPS was diagnosed. Early immunosuppressive treatment with pulse methylprednisolone and cyclophosphamide and plazmaferez was started. Noninvasive positive pressure ventilation (NPPV was used for severe hypoxemia. Haemolytic anemia and thrombocytopenia developed under plasmaphresis treatment. Early treatment resulted with remmission. In conclusion, the current case showed that Goodpasture’s syndrome may have a favorable prognosis with early diagnosis and proper treatments including NPPV.

    For 30 years, Phelan and co-workers described a syndrome characterised by neonatal hypotonia, global developmental delay, strongly impaired speech, sleep disturbances and hyperreactivity to sensory stimuli. This Phelan-McDermid syndrome (PMS), also presenting with symptoms from the autism spectrum and a higher risk of developing seizure disorders, may be caused by a deletion of chromosome 22q13 or by a mutation in the SHANK3 gene. Its core psychopathological phenotype comprises symptoms from the bipolar spectrum for which generally treatment with a mood-stabilising anticonvulsant in combination with an atypical antipsychotic seems to be most effective. In addition to two elsewhere published adolescent patients, we here describe in detail the history of an adult male patient with PMS caused by a SHANK3 mutation in whom successive treatment regimens with antipsychotics and mood-stabilising anticonvulsants were all ineffective. Ultimately, addition of lithium to existing olanzapine therapy led to enduring stabilisation of mood and behaviour. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Donnai-Barrow syndrome [Faciooculoacousticorenal (FOAR) syndrome; DBS/FOAR] is a rare autosomal recessive disorder resulting from mutations in the LRP2 gene located on chromosome 2q31.1. We report a unique DBS/FOAR patient homozygous for a 4-bp LRP2 deletion secondary to paternal uniparental isodisomy for chromosome 2. The propositus inherited the mutation from his heterozygous carrier father, whereas the mother carried only wild-type LRP2 alleles. This is the first case of DBS/FOAR resulting from uniparental disomy (UPD) and the fourth published case of any paternal UPD 2 ascertained through unmasking of an autosomal recessive disorder. The absence of clinical symptoms above and beyond the classical phenotype in this and the other disorders suggests that paternal chromosome 2 is unlikely to contain imprinted genes notably affecting either growth or development. This report highlights the importance of parental genotyping in order to give accurate genetic counseling for autosomal recessive disorders. 2008 Wiley-Liss, Inc.

  20. The fluid mechanics of root canal irrigation.

    Gulabivala, K; Ng, Y-L; Gilbertson, M; Eames, I

    2010-12-01

    Root canal treatment is a common dental operation aimed at removing the contents of the geometrically complex canal chambers within teeth; its purpose is to remove diseased or infected tissue. The complex chamber is first enlarged and shaped by instruments to a size sufficient to deliver antibacterial fluids. These irrigants help to dissolve dying tissue, disinfect the canal walls and space and flush out debris. The effectiveness of the procedure is limited by access to the canal terminus. Endodontic research is focused on finding the instruments and clinical procedures that might improve success rates by more effectively reaching the apical anatomy. The individual factors affecting treatment outcome have not been unequivocally deciphered, partly because of the difficulty in isolating them and in making the link between simplified, general experimental models and the complex biological objects that are teeth. Explicitly considering the physical processes within the root canal can contribute to the resolution of these problems. The central problem is one of fluid motion in a confined geometry, which makes the dispersion and mixing of irrigant more difficult because of the absence of turbulence over much of the canal volume. The effects of treatments can be understood through the use of scale models, mathematical modelling and numerical computations. A particular concern in treatment is that caustic irrigant may penetrate beyond the root canal, causing chemical damage to the jawbone. In fact, a stagnation plane exists beyond the needle tip, which the irrigant cannot penetrate. The goal is therefore to shift the stagnation plane apically to be coincident with the canal terminus without extending beyond it. Needle design may solve some of the problems but the best design for irrigant penetration conflicts with that for optimal removal of the bacterial biofilm from the canal wall. Both irrigant penetration and biofilm removal may be improved through canal fluid

  1. Differentiation of root canal morphology – a review of the literature

    Full Text Available The morphological diversity of the inner anatomy of root canals in human permanent teeth is an issue mainly described in endodontics research. In recent years, it is a relatively new point in anthropological studies because it varies by sex, geographic and ethnic circumstances. An unusual number of root canals or their specific systems can differentiate populations around the world. The multiplicity of available methods for detecting root canal systems helps to better understand their complexity; however, most cannot be applied to anthropology due to limitations that occur in the bioarcheological material. Thorough knowledge of the heterogeneity and internal anatomy of the root canals supplies numerous classification systems proposed and improved over the years by many authors. A limited number of studies in the anthropological literature and future research will shed light onto the internal tooth morphology in historical populations. The aim of this paper is to describe various classification systems of root canals applied in endodontics. However, due to the often poor state of preservation and damage of archaeological derived remains, it seems that the best method is the approach that is the simplest and least complicated.

    A case is reported of a 26-year-old primiparous woman in the 32nd week of gestation who presented to the emergency department with the symptoms of a severe headache, nausea and vomiting. The patient was diagnosed with preeclampsia that later progressed to eclampsia. This state was characterized by a sudden onset of a headache and diplopia that advanced to cortical blindness and precipitated significant alterations in mental status, most notable being global amnesia that resolved within 48 h. A post-partum magnetic resonance imaging of the brain in FLAIR mode revealed multiple cortico-subcortical areas of hyperintense signals suggestive of edematous lesions that chiefly involved occipital and parietal lobes with additional atypical manifestations. Such radiologic findings suggested a posterior reversible encephalopathy syndrome variant with the global amnesia as an extraordinary constituent. This unique feature should be acknowledged when treating a preeclamptic or hypertensive patient that exhibits neurological symptomatology and vision disturbances.

    2009-03-01

    Full Text Available Abstract Background Ataxia-Telangiectasia syndrome is characterized by progressive cerebellar dysfunction, conjuctival and cutaneous telangiectasias, severe immune deficiencies, premature aging and predisposition to cancer. Clinical and radiographic evaluation for malignancy in ataxia-telangiectasia patients is usually atypical, leading to delays in diagnosis. Case presentation We report the case of a 20 year old ataxia-telangiectasia patient with gastric adenocarcinoma that presented as complete gastric outlet obstruction. Conclusion A literature search of adenocarcinoma associated with ataxia-telangiectasia revealed 6 cases. All patients presented with non-specific gastrointestinal complaints suggestive of ulcer disease. Although there was no correlation between immunoglobulin levels and development of gastric adenocarcinoma, the presence of chronic gastritis and intestinal metaplasia seem to lead to the development of gastric adenocarcinoma. One should consider adenocarcinoma in any patient with ataxia-telangiectasia who presents with non-specific gastrointestinal complaints, since this can lead to earlier diagnosis.

    To assess the anatomy of the mandibular lingual vascular canals with the use of computed tomography (CT). Seventy consecutive patients underwent preimplantation CT of the mandible. CT images were obtained on axial plane by using a bone reconstruction algorithm and then processed with dedicated software (Dentascan). The number of lingual vascular canals, the diameter of their entrance foramina and the distance of the foramina from the symphysis menti and from the lower edge of the mandible were measured in each patient. The median superior canal (MSC), the median inferior canal (MIC), the lateral mesial canals (LMC) and the lateral distal canals (LDC) were evaluated separately. 0 to 5 canals were found in each patient. The MSC was found to be present in 98.6% of cases; the mean diameter of the entrance foramen was 0.85+/-0.28 mm located adjacent the symphysis menti and 11.3+/-2.6 mm from the inferior margin of the mandible. The MIC was found to be present in 32.9% of cases; the mean diameter of the entrance foramen was 0.58+/-0.21 mm located adjacent the symphysis menti and 5.5+/-2.2 mm from the inferior margin of the mandible. LMCs were found to be present in 38.6% of cases; the mean diameter of their entrance foramina was 0.60+/-0.24 mm located 5.1+/-2.5 mm from the symphysis menti and 6.3+/-3.2 mm from the inferior margin of the mandible. LDCs were found to be present in 48.6% of the patients; the mean diameter of their entrance foramina was 0.58+/-0.19 mm located 19.3+/-7.3 mm from the symphysis menti and 6.6+/-5.4 mm from the inferior margin of mandible. Dental CT detects the lingual vascular canals of the mandible in a high percentage of subjects and allows a good demonstration of their number, location and entrance foramen diameter. The evaluation of these canals is important in the preoperative planning of dental implants or in the planning of dental surgery in general so as to avoid bleeding due to damage of the vessels present in these canals.

  5. Cochlear Implantation in Patients with Keratitis-Ichthyosis-Deafness Syndrome: A Report of Two Cases

    2017-01-01

    Full Text Available Background. Keratitis-ichthyosis-deafness (KID syndrome is a syndrome which presents with hearing loss and visual and keratinization disorders. In such patients, hearing aids cannot be effectively used in the rehabilitation of hearing loss because of the frequent blockage of the external ear canal with epithelial debris and due to dry and tense skin of the external ear canal. Moreover, severe or profound hearing loss also limits the benefits gained from the conventional hearing aids. On the other hand, cochlear implantation is a method that has been used in limited cases in the literature. Case Report. This study presents the results of cochlear implantation applied in our clinic to two children who had been diagnosed with KID. Audiological assessments before and after the cochlear implant operation were performed using pure-tone audiometry, immittance audiometry, and auditory brainstem response (ABR, and the postoperative follow-up was conducted using pure-tone audiometry. Conclusion. Skin problems, visual disturbances, and other additional problems complicate the short-term and long-term rehabilitation after implantation in individuals with KID syndrome. Close monitoring should be exercised due to possible skin complications that may develop during the postoperative period. The families and rehabilitation teams should be warned about the possible visual disturbances and skin complications.

    Full Text Available Bardet-Biedl syndrome (BBS is a rare autosomal recessive disorder with clinical and genetic heterogeneity. This syndrome was first described by Laurence and Moon in 1866 and additional cases were described by Bardet and Biedl between 1920 and 1922. The main features are obesity, polydactyly, pigmentary retinopathy, learning disabilities, various degrees of intellectual impairment, hypogonadism, and renal abnormalities. Bardet-Biedl syndrome is both phenotypically and genetically heterogeneous. Clinical diagnosis is based on the presence of 4 of the 5 cardinal features. The authors present a typical case of pigmentary retinopathy due to Bardet-Biedl syndrome and made a brief commentary about the disease's cardinal manifestations.A síndrome de Bardet-Biedl (BBS é uma desordem autossômica recessiva rara, com heterogeneidade clínica e genética.

    Full Text Available A C-shaped canal with varying configuration is commonly observed in single-rooted mandibular second molars. Cooke and Cox (1979 first documented the C-shaped canal in endodontic literature. The presence of high incidence of transverse anastomoses, lateral canals, and apical deltas makes it difficult to clean and seal the root canal system in these teeth. The main reason for failure in endodontic treatment of mandibular second molars is the inability to detect the presence of C-shaped canals prior to an endodontic therapy. This case report presents successful management of two rare cases of C-shaped canal configurations.

  10. Function of lateral line canal morphology.

    Klein, Adrian; Bleckmann, Horst

    2015-01-01

    Fish perceive water motions and pressure gradients with their lateral line. Lateral line information is used for prey detection, spatial orientation, predator avoidance, schooling behavior, intraspecific communication and station holding. The lateral line of most fishes consists of superficial neuromasts (SNs) and canal neuromasts (CNs). The distribution of SNs and CNs shows a high degree of variation among fishes. Researchers have speculated for decades about the functional significance of this diversity, often without any conclusive answers. Klein et al. (2013) examined how tubules, pore number and pore patterns affect the filter properties of lateral line canals in a marine teleost, the black prickleback (Xiphister atropurpureus). A preliminary mathematical model was formulated and biomimetic sensors were built. For the present study the mathematical model was extended to understand the major underlying principle of how canal dimensions influence the filter properties of the lateral line. Both the extended mathematical model and the sensor experiments show that the number and distribution of pores determine the spatial filter properties of the lateral line. In an environment with little hydrodynamic noise, simple and complex lateral line canals have comparable response properties. However, if exposed to highly turbulent conditions, canals with numerous widely spaced pores increase the signal to noise ratio significantly. © 2014 International Society of Zoological Sciences, Institute of Zoology/Chinese Academy of Sciences and Wiley Publishing Asia Pty Ltd.

    The purpose of this study was to evaluate the canal cleaning ability of three novel endodontic rotary instruments and compare with ProTaper files as a control in apical third of root canals under scanning electron microscopy (SEM). Eighty freshly extracted mandibular premolars were selected according to inclusion criteria. Buccal cusp tips were ground to ensure having a flat coronal reference point with a total tooth length of 16 mm for all samples. Teeth were divided equally into four groups: Group I (ProTaper group), Group II (ProTaper next group), Group III (variable taper group), and Group IV (self-adjusting file [SAF] group). Using SEM, the dentinal surfaces were observed and rated at apical thirds with a magnification of ×1000 for the presence/absence of smear layer and debris. Descriptive analysis was performed, and analysis of variance with Bonferroni post hoc test was carried out for comparison between the groups, at a significance level of 0.05. There was statistically significant difference between Group II and Group IV for debris (P = 0.047) and smear layer (P = 0.037). In apical third of root canal, SAF showed statistically significant canal cleaning ability due to combined effect of continuous streaming irrigation with effectively replacing the irrigant from the apical portion of the root canal, irrigants activation through the creation of turbulence, and its self-adapting design to root canal anatomy with a scrubbing motion on the canal walls.

    Since complete debridement of the root canals of the primary teeth is not practically possible due to the highly variable root canal anatomy, success of the endodontic therapy depends partly on the use ofantibacterial irrigating agents and root canal filling materials. Recent literature indicates that anaerobes comprise a majority of the bacteria in necrotic root canals ofprimary teeth. The study determined the antibacterial effectiveness of four root canal filling materials namely Calcium hydroxide, Zinc oxide eugenol, Vitapex and Metapex against microbial specimens obtained directly from necrotic root canals of primary teeth. Microbial specimens were collected using sterile paper points, from 15 primary maxillary and mandibular posterior teeth of randomly selected children in the age group of 4-10 years with infected non vital primary teeth, requiring pulpectomy procedure. The microbial specimens collected were subjected to microbiological analysis and the antimicrobial potential of root canal filling materials were tested using Agar diffusion technique. were statistically analyzed using one-way ANOVA. Facultative/Aerobic organisms were isolated in all the cases, anaerobic organisms were isolated in 80% of the cases, and Candida albicans was isolated in 1 case. ZOE showed superior inhibitory activity against most of the organisms isolated followed by Vitapex, Calcium hydroxide and Metapex in descending order. Our data may be useful as a guide for relative antimicrobial effectiveness or non-effectiveness of the materials employed. In vivo studies are required to state the specific antimicrobial activity and merits and demerits of any of the test filling material.

    The C-shaped root canal constitutes an unusual root morphology that can be found primarily in mandibular second permanent molars. Due to the complexity of their structure, C-shaped root canal systems may complicate endodontic interventions. A thorough understanding of root canal morphology is therefore imperative for proper diagnosis and successful treatment. This review aims to summarize current knowledge regarding C-shaped roots and root canals, from basic morphology to advanced endodontic procedures. To this end, a systematic search was conducted using the MEDLINE, BIOSIS, Cochrane Library, EMBASE, Google Scholar, Web of Science, PLoS and BioMed Central databases, and many rarely cited articles were included. Furthermore, four interactive 3D models of extracted teeth are introduced that will allow for a better understanding of the complex C-shaped root canal morphology. In addition, the present publication includes an embedded best-practice video showing an exemplary root canal procedure on a tooth with a pronounced C-shaped root canal. The survey of this unusual structure concludes with a number of suggestions concerning future research efforts. PMID:24483229

    Full Text Available Decreased fetal movement (DFM perceived by pregnant women sometimes indicates imminent fetal jeopardy. It is unknown whether this also holds true for twin pregnancy. A 27-year-old primiparous woman with monochorionic diamniotic (MD pregnancy had a slight difference of amniotic fluid volume at 312/7 weeks of gestation. DFM only in one twin at 314/7 weeks of gestation prompted her to receive urgent consultation. Since cardiotocogram indicated absent variability of one twin, we performed Cesarean section. Male infants weighing 2060 g and 1578 g were delivered; hemoglobin was 20.7 versus 10.8 g/dL, respectively; cardiothoracic ratio was 70% versus 44%, respectively, indicating acute twin-to-twin transfusion syndrome (TTTS. The recipient infant had heart failure, which was still observed at 1 month postpartum. In conclusion, maternal perception of DFM indicated imminent fetal death or jeopardy caused by acute TTTS, suggesting that education regarding DFM for women with twin pregnancy may be clinically important.

    Full Text Available Podocin mutations (NPHS2 gene are mostly responsible for steroid-resistant nephrotic syndrome (SRNS of childhood onset. Patients with NPHS2 gene mutations do not respond to corticoids and other immunosuppressive agents; partial remission can be rarely induced by cyclosporin A. We present a boy, where SRNS was diagnosed within first year of life. By the age of 15 years, proteinuria reached 9000 mg/24 h, cholesterolemia 15 mmol/L, albuminemia 19.6 g/L, in spite of combined therapy with cyclosporine A, methylprednisolone, enalapril and losartan. At that time a combined heterozygous form of two NPHS2 gene mutations (p.R138Q and p.V290M was diagnosed, methylprednisolone was discontinued and patient underwent ten plasmapheresis procedures. This resulted in clinical improvement (proteinuria 3000 mg/24 h, S-cholesterol 6 mmol/L, albumin 30g/L lasting for three years. In conclusion, plasmapheresis can result in clinical improvement and stabilization of SRNS caused by podocine mutation, before renal replacement therapy is initiated.

    Cockayne Syndrome (CS) is an autosomal recessive disorder that causes neurological regression, growth failure and dysmorphic features. We describe a Chinese female child with CS caused by deletions of exon 4 of ERCC8 on one chromosome and exons 1-12 on the other chromosome. By using chromosomal microarray, multiplex ligation-dependant probe analysis and long range PCR, we showed that she inherited a 277 kb deletion affecting the whole ERCC8 gene from the mother and a complex rearrangement resulting in deletion of exon 4 together with a 1,656 bp inversion of intron 4 from the father. A similar complex rearrangement has been reported in four unrelated Japanese CS patients. Analysis of the deletion involving exon 4 identified LINE and other repeat elements that may predispose the region to deletions, insertions and inversions. The patient also had insulin-dependent diabetes mellitus, a rare co-existing feature in patients with CS. More research will be needed to further understand the endocrine manifestations in CS patients. Copyright © 2015 Elsevier B.V. All rights reserved.

    Disorders in the regulation of the alternate complement pathway often result in complement-mediated damage to the microvascular endothelium and can be associated with both glomerulonephritis and atypical haemolytic uraemic syndrome. Inherited defects in complement regulatory genes or autoantibodies against complement regulatory proteins are predictive of the severity of the disease and the risk of recurrence post kidney transplantation. Heterozygous mutations in CD46, which codes for a transmembrane cofactor glycoprotein membrane cofactor protein, usually have a lower incidence of end-stage kidney disease and decreased risk of recurrent disease post transplant, as wild-type membrane cofactor protein is present in the transplanted kidney. However, some patients with CD46 mutations have a second variant in other complement regulatory genes increasing the severity of disease. The following case report illustrates the course of a young adult patient with end-stage kidney disease initially ascribed to seronegative systemic lupus erythematosus, who presented with biopsy-proven thrombotic microangiopathy following kidney transplantation. It highlights the complexity associated with disorders of complement regulation and the need for a high index of suspicion and genetic testing in patients who present with thrombotic microangiopathy post-transplant. © 2017 Asian Pacific Society of Nephrology.

    Hyponatremia is a common electrolyte disorder in cancer patients and has been associated with poor prognosis. A frequent cause of cancer-related hyponatremia is the syndrome of inappropriate antidiuretic hormone (SIADH). This study was a post hoc subgroup analysis of the SALT-1 (Study of Ascending Levels of Tolvaptan in Hyponatremia) and SALT-2 clinical trials. Hyponatremic subjects with SIADH and cancer received the oral selective vasopressin V2-receptor antagonist tolvaptan (n = 12) or matching placebo (n = 16) once-daily for 30 days. The initial tolvaptan dose (15 mg) was titrated over 4 days to 30 or 60 mg per day, as needed, according to serum sodium level and tolerability. Baseline serum sodium levels in the SIADH/cancer cohort of the SALT trials was 130 and 128 mEq/L for tolvaptan and placebo, respectively. Mean change from baseline in average daily serum sodium AUC for tolvaptan relative to placebo was 5.0 versus -0.3 mEq/L (P post hoc study of the SALT trial population, oral tolvaptan was an effective and safe therapy for the treatment of hyponatremia in subjects with SIADH and cancer. © 2016 The Authors.

    Floating-Harbor syndrome (FHS) is a rare autosomal dominant disorder characterized by short stature, skeletal malformations, speech delay, and dysmorphic facial appearance. Recently, mutations in SRCAP encoding a coactivator for cAMP-response element binding protein (CREB)-binding protein have been identified in small number of patients with FHS. Here, we report on long-term follow-up data of a male patient with a SRCAP mutation. The patient presented with mild hypothyroidism and renal hypouricemia, in addition to several FHS-compatible features including growth impairment, cognitive disability, facial dysmorphisms, and hypertension. He showed delayed bone age from infancy to 9 years of age and markedly accelerated bone age with the formation of cone-shaped epiphyses and early epiphysial fusions after the onset of puberty. His pubertal sexual development was almost age appropriate. Two-year treatment with growth hormone (GH) did not significantly improve the growth velocity. Molecular analysis identified a de novo heterozygous nonsense mutation (p.R2444X) in the last exon of SRCAP, which has been most common mutation detected in patients from other ethnic groups. These results indicate that perturbed skeletal maturation from infancy through adolescence is a characteristic feature in patients with SRCAP mutations. Furthermore, our data imply that GH therapy exerted only a marginal effect on the growth of this patient, and that renal hypouricemia may be a novel complication of FHS. © 2013 Wiley Periodicals, Inc.

    A woman with psychomotor developmental delay, congenital glaucoma, and distinctive facial features, and a short neck was diagnosed with Jacobsen syndrome (JBS) at age 40 years. A previously reported balanced translocation between chromosome 11 and 22 instead showed an unbalanced translocation by a microarray-based comparative hybridization analysis with the final karyotype of 46,XX,der(11)t(11;22)(q23.3;q11.21),del(22)(q11.21) dn. The breakpoint of chromosome 11 was determined to be at TECTA and not near the apolipoprotein gene cluster site or the fragile site (FRA11B), which are commonly seen in patients with t(11;22) and patients with typical 11q deletions, respectively. Although the phenotypic features of the patient, including psychomotor developmental delay, distinctive features, and mild thrombocytopenia, were consistent with JBS, congenital glaucoma, which is an uncommon finding of JBS, was the most prominent condition during her natural history.
