    A 52-year-old Mexican man presented with asymptomatic, bilaterally symmetrical lipid infiltrates of the cornea and adjacent limbus. No evidence of previous ocular disease or systemic disorder of lipid metabolism could be detected. Penetrating keratoplasty of the right eye was required. The cornea was rigid and thick, with posterior bulging into the anterior chamber. Light microscopy revealed deep corneal lipid granules, foamy histiocytes, vascularisation, and chronic non-granulomatous inflammation. Transmission electron microscopy showed extracellular lipid spaces and numerous intracytoplasmic lipid vacuoles in histiocytes, keratocytes, conjunctival epithelium, and the endothelium of blood vessels in the corneal stroma and adjacent limbal conjunctiva. Histochemical analysis revealed the presence of neutral fats, free fatty acids, cholesterol, and phospholipids. Images PMID:3395592

    Patient: Male, 21 Final Diagnosis: Idiopathic bilateral external jugular vein thrombosis Symptoms: Face engorgement • neck swelling Medication: — Clinical Procedure: None Specialty: Hematology Objective: Unknown ethiology Background: Vein thrombosis is mainly determined by 3 factors, which constitute a triad called Virchow’s triad: hypercoagulability, stasis, and endothelial injury. Venous thrombosis commonly occurs in the lower extremities since most of the blood resides there and flows against gravity. The veins of the lower extremities are dependent on intact valves and fully functional leg muscles. However, in case of valvular incompetency or muscular weakness, thrombosis and blood stasis will occur as a result. In contrast, the veins of the neck, specially the jugulars, have distensible walls which allow flexibility during respiration. In addition, the blood directly flows downward towards the heart. Nevertheless, many case reports mentioned the thrombosis of internal jugular veins and external jugular veins with identified risk factors. Jugular vein thrombosis has previously been associated in the literature with a variety of medical conditions, including malignancy. Case Report: This report is of a case of idiopathic bilateral external jugular vein thrombosis in a 21 year-old male construction worker of Southeast Asian origin with no previous medical history who presented with bilateral facial puffiness of gradual onset over 1 month. Doppler ultrasound and computed tomography were used in the diagnosis. Further work-up showed no evidence of infection or neoplasia. The patient was eventually discharged on warfarin. The patient was assessed after 6 months and his symptoms had resolved completely.

    It is unknown if uni- or bilateral lung transplant is best for treatment of usual idiopathic pulmonary fibrosis. We reviewed our single-center experience comparing both treatments. Between 2002 and 2011, one hundred thirty-eight patients at our institution underwent a lung transplant. Of these, 58 patients presented with idiopathic pulmonary fibrosis (56.9%) and were the focus of this study. Thirty-nine patients received a single lung transplant and 19 patients a bilateral sequential lung transplant. The mean patient age was 54 ± 10 years, and 69% were male. The intraoperative course was uneventful, save for 7 patients who needed extracorporeal membrane oxygenation support. Three patients had respiratory failure before the lung transplant that required mechanical ventilation and was supported by extracorporeal membrane oxygenation. Elevated pulmonary artery pressure > 40 mm Hg was identified as an independent predictor of early mortality by uni- and multivariate analysis (P = .01; OR 9.7). Using a Cox regression analysis, postoperative extracorporeal membrane oxyge-nation therapy (P = .01; OR 10.2) and the need for > 10 red blood cell concentrate during the first 72 hours after lung transplant (P = .01; OR 5.6) were independent predictors of long-term survival. Actuarial survival at 1 and 5 years was 65.6% and 55.3%, with no significant between-group differences (70.6% and 54.3%). Lung transplant is a safe and curative treatment for idiopathic pulmonary fibrosis. According to our results, unilateral lung transplant for idiopathic pulmonary fibrosis is an alternative to bilateral lung transplant and may affect the allocation process.

    We report on the case of bilateral avascular osteonecrosis (AVN) of the lunate and triquetrum in a 45-year-old woman without any relevant medical history for which the cause could not be established. She was treated conservatively with splinting and analgesics. The patient was able to pursue her work and hobbies with subnormal range of motion at 1-year follow-up. AVN of the triquetrum is very rare, as it is a richly vascularized bone. The presence of AVN in multiple carpal bones has only been described in patients receiving high doses of corticosteroids. To our knowledge, there are no other cases of idiopathic AVN of multiple carpal bones in the literature.

    INTRODUCTION Exostoses in paranasal sinuses have been reported in the otolaryngology literature, but they have not been described in the dental literature to our knowledge. The aim of this article is to describe an idiopathic and rare case of bilateral exostosis obtained by cone-beam computed tomography. PRESENTATION OF CASE The case shows a healthy and asymptomatic patient with a different size and form of exostoses in both maxillary sinuses. DISCUSSION It is difficult to clinically diagnose the antral exostosis due the asymptomatic nature of this condition, unless the approach would be through endoscope. Sometimes this condition is related with nasal irrigants, however in this case the patient asserted not having used nasal irrigation ever; thus, it is impossible to relate this kind of treatment as a principal cause. CONCLUSION The published data of exostoses in maxillary sinus seem to be limited in the dental literature, and this condition is important to consider in an implant treatment planning. Also, it is important to perform a follow-up of the cases in trying to find the possible causes of exostosis. PMID:25128728

    The wrist drop, also called carpoptosis or drop hand, is a common clinical presentation in case of peripheral damage to the radial nerve. But what about the picture of a bilateral finger/wrist drop?! We report the case of a 61-year-old female patient who was admitted to the hospital for myocardial infarction. Subsequently she developed a right dominant bilateral wrist drop. Further neurological examination revealed a positive Wartenberg sign pointing towards a central motoric dysfunction. The following native cerebral CT scan demonstrated bilateral hypodense lesions in both hand knobs in the precentral gyri. Subsequent MRI confirmed acute cerebral infarction in these two but also several other, clinically silent, locations. Further diagnostic work-up revealed a hypokinetic cardiac apex suggesting cardiac embolism to be the cause for cerebral thrombembolism and the clinically leading symptom of right-dominant bilateral finger/wrist drop. Besides the case presentation also the differential diagnosis and clinical test for diagnostic work-up of wrist drops are presented and discussed.

  11. [Idiopathic hypersomnia of the central nervous system].

    PubMed

    Bové-Ribé, A

    Idiopathic hypersomnia of the central nervous system is a cause of excessive diurnal somnolence which affects 5-10% of the patients who attend sleep clinics for this reason. We describe three male patients who consulted for excessive diurnal somnolence. Nocturnal polysomnographic studies followed by tests for multiple latencies of sleep were done. In all cases there was confirmation of lengthening of the time of nocturnal sleep with normal phases of sleep and an increase in the number of sleep spindles in phase II. Similarly there was an average latency of sleep of less than 10 minutes and fewer than two phases of REM in the multiple latencies test. All patients improved with drugs stimulating vigil, two of them with centramine and the third with methilphenidate. We consider the clinical data the polysomnographic criteria which help to establish the diagnosis.

    Tic disorders are commonly considered to be childhood syndromes. Newly presenting tic disorders during adulthood are uncommon and mostly described in relation to an acquired brain lesion or as incidental tics, particularly in context with other neurological or psychiatric diseases. Tic disorder involving the ears is extremely uncommon with only few studies in English literature. In the present case, we describe an adult patient with new-onset idiopathic tics disorder involving both ears, causing social embarrassment. In addition, our patient had recent onset of the tics without any childhood or family history of tic disorders. The single most important component of management is an accurate diagnosis. At the same time, tics should be differentiated from other movement disorders such as chorea, stereotypy, and dystonias.

    Idiopathic bilateral vocal cord paralysis (VCP) is a rare and difficult condition often undiagnosed and frequently confused with asthma and other respiratory conditions. Accurate diagnosis is crucial since 80% of cases patients require surgical intervention, such as tracheostomy or laser surgery, to relieve symptoms. The "gold standard" for diagnosing VCP has been laryngoscopy. In this case study, we demonstrate for the first time that idiopathic bilateral VCP can be accurately diagnosed by means of a novel noninvasive methodology: dynamic volume 320-slice computed tomography larynx. Three-dimensional reconstruction of laryngeal motion during the breathing cycle permitted functional assessment of the larynx showing absence of vocal cord movements. The new methodology may be valuable for noninvasive diagnosis of vocal cord movement disorders before and for follow-up after surgery.

    2015-01-01

    Introduction: Bilateral Flexion Deformity commonly results secondary to cerebral palsy, poliomyelitis, haemophilia etc. It is accompanied by valgus deformity and external rotation at knee in long standing cases secondary to the contracture of the iliotibial tract. Flexion deformity at knees is an impediment to the normal ambulation and is difficult to address. Case Report: A 34 year old male presented with bilateral knee stiffness. He had multifocal tuberculosis and was bed ridden for almost a year and consequently developed bilateral knee flexion deformity of 60o with further flexion upto 120o. Patient was treated with gradual distraction using a modified external fixator and achieved full correction at the end of 6 weeks. At final followup patient was walking comfortably and was able to squat and sit crossed legged. Conclusion: Idiopathic isolated bilateral flexion deformity of knees is very rare and is an impediment to normal ambulation. Arthrodiastasis with indigenously designed fixator using the Ilizarov principle and modified fixator is a simple, efficient and cost effective treatment for flexion deformity of knee. PMID:27299020

    We review our experience with four patients who presented to our Medical Center from 2005-2015 with adult idiopathic occlusion of the foramen of Monro (FM). All patients underwent CT scanning and MRI. Standard MRI was performed in each patient to rule out a secondary cause of obstruction (T1-weighted without- and with gadolinium, T2-weighted, fluid-attenuated inversion recovery [FLAIR] and diffusion-weighted imaging [DWI] protocols). When occlusion of the FM appeared to be idiopathic, further high-resolution MRI with multiplanar reconstructions for evaluation of stenosis or an occluding membrane at the level of the FM was performed (T1-weighted without- and with gadolinium, T2-weighted 3D turbo spin-echo). Occlusion of the FM was due to unilateral stenosis and septum pellucidum deviation in two patients, to an occluding membrane in one, and to bilateral stenosis in one patient. Urgent surgical intervention is mandatory when there are signs of increased intracranial pressure while asymptomatic patients may be managed conservatively. In this patient series, truly bilateral stenotic obstruction of the FM was best managed with ventriculoperitoneal shunt and patients with membranous obstruction or unilateral stenosis with septum deviation were treated endoscopically.

    Central Retinal Vein Occlusion (CRVO) is a severe retinal pathology, which causes visual impairment usually after the age of 40. Mostly unilateral, less than 10% of cases are bilateral. Affected young adults (under the age of 40), usually exhibit a hidden, underlying systemic disease. Thorough testing has to be done in order to spot the pathogenic agent. We present the case of a 25 years old woman with bilateral CRVO caused by Diaphragmatic Eventration and Chronic Respiratory Failure. PMID:25705293

    Remitting seronegative symmetrical synovitis with pitting edema syndrome is characterized by symmetrical synovitis with pitting edema in the dorsum of the hands or feet. Most cases of remitting seronegative symmetrical synovitis with pitting edema syndrome are idiopathic, but some are secondary to malignancy, autoimmune disease, or neurodegenerative disorders. Pleural and pericardial effusions are unusual complications in idiopathic remitting seronegative symmetrical synovitis with pitting edema syndrome. A 74-year-old Japanese woman presented to our hospital with arthralgia and pitting edema in her feet. She had pain in multiple joints, peripheral edema, and a markedly elevated erythrocyte sedimentation rate. Enhanced computed tomography and laboratory data showed no evidence of malignancy. These findings suggested that she had idiopathic remitting seronegative symmetrical synovitis with pitting edema syndrome. She also developed respiratory distress because of bilateral pleural and pericardial effusions. Laboratory data showed that serum vascular endothelial growth factor and interleukin-6 were significantly elevated. After administration of steroids, her pleural and pericardial effusions decreased and finally disappeared. Furthermore, vascular endothelial growth factor and interleukin-6 decreased when the pleural and pericardial effusions disappeared. Here we report the case of a patient with idiopathic remitting seronegative symmetrical synovitis with pitting edema syndrome associated with life-threatening complications, including bilateral pleural and pericardial effusions during the course of the illness, which led to respiratory failure and atrial fibrillation. Elevated vascular endothelial growth factor and interleukin-6 may be associated with the cause of pleural and pericardial effusions in idiopathic remitting seronegative symmetrical synovitis with pitting edema syndrome.

    Abstract Radiofrequency thermocoagulation (RFT) is an effective treatment for trigeminal neuralgia, but consensus regarding an optimal treatment temperature is lacking. While treatment temperatures ranging from 60°C to 95°C have been reported, RFT at too high a temperature is often followed by serious complications, and comparative evaluations of RFT at different temperatures in a single study are rare. This current prospective cohort study was to compare immediate and long-term outcomes of RFT at varying temperatures in patients with bilateral idiopathic trigeminal neuralgia (ITN) of maxillary division of trigeminal nerve (V2), mandibular division of trigeminal nerve (V3), and V2+V3, including pain relief, complications, recurrence rate, and patient satisfaction. From May 2011 to April 2016, 62 consecutive patients with bilateral ITN of V2, V3, and V2+V3 were enrolled in the study. These patients underwent bilateral RFT at 68°C and 75°C, respectively, using the same RF parameters. Side-to-side results, including pain relief, complications, and patient satisfaction, were compared during a 5-year follow-up period. Overall pain relief was satisfactory after RFT. The rate of pain relief after treatment at 75°C was slightly higher than at 68°C (P > 0.05). The pain-free rate was 95.1% at 75°C and 93.5% at 68°C at 1 year, 84.3% and 78.1% at 3 years, and 80.7% and 74.4% at 5 years. There were 10 and 13 cases of recurrence, respectively, and 6 cases of bilateral recurrence. The incidence and severity of complications were greater at 75°C (P < 0.05) than at 68°C, and therefore the patient satisfaction at the higher temperature was lower (P < 0.05). Patients with bilateral ITN who underwent RFT at different temperatures had consistent pain relief after RFT at both 75°C and 68°C, but there were fewer and less severe complications at 68°C, which was accompanied by greater patient satisfaction. This suggests that RFT at lower temperatures may be

    Idiopathic chondrolysis of the hip usually develops in adolescents and is a disease characterized by gradual degenerative changes of the hyaline cartilage surrounding the head of the femur. It eventually decreases the hip joint space and causes limitations in the hip joint range of motion due to pain. The authors had experienced an unusual case of bilateral idiopathic chondrolysis of the hip in an 54 year-old male; thus, we report the treatment results and literature reviews in this case report.

    AIM To evaluate the axial length (AXL) in unilateral idiopathic central serous chorioretinopathy (CSC). METHODS This retrospective case-control study was comprised of a consecutive case series of 35 patients with acute unilateral idiopathic CSC, and age- and sex-matched 50 control eyes. AXL of both eyes of unilateral CSC patients and the control eyes were investigated. AXL was measured by ultrasonic biometry, and the adjusted AXL was calculated for CSC eyes as measured AXL plus differences of foveal thickness between CSC and normal fellow eyes in millimeters. The main outcome measures were comparison of AXL between CSC, fellow and control eyes. RESULTS The mean age of 35 CSC patients was 45.5y, and 31 males were included. The adjusted AXL of CSC eyes was 23.52 mm, and the AXL of fellow eyes was 23.46 mm, and of control eyes 23.94 mm. The AXL of both CSC and fellow eyes were significantly shorter than control eyes (CSC vs control, P=0.044; fellow vs control, P=0.026). There was no statistically significant difference in AXL between CSC and fellow eyes. CONCLUSION In unilateral idiopathic CSC, the AXL of CSC and fellow eyes are shorter than that of control eyes. Short AXL may be related with choroidal circulation abnormality in CSC. PMID:27275428

    Vertigo attacks in IBV patients involving both the superior and inferior vestibular nerve systems were significantly more severe than vertigo attacks in patients with selective involvement of the inferior vestibular nerve system alone. To investigate the relationship between the frequency and duration of vertigo and the affected vestibular nerve system in idiopathic bilateral vestibulopathy (IBV). This study categorized 44 IBV patients into the following three sub-groups according to the affected vestibular nerve system: superior, inferior, and mixed type. These patients were also categorized into the following three sub-groups according to their clinical time course: progressive type showing no episodes of vertigo, sequential type showing recurrent vertigo attacks and single-attack type showing a single episode of vertigo. Ten, 11 and 23 patients were classified as the superior, the inferior, and the mixed type, respectively. Seventeen, 23, and four patients were classified as the progressive, the sequential, and the single-attack type, respectively. For the patients having one or more vertigo attacks, the duration of the vertigo attack was longer than 24 h in 69% of the mixed type, and the duration of vertigo in the mixed type was significantly longer than that in the inferior type (p < 0.05).

A 29-year-old man presented with head injury following road traffic accident. Posterior segment evaluation revealed CRAO in both eyes. The patient was treated for CRAO in the form of immediate ocular massage, paracentesis, intravenous mannitol and transdermal isosorbide dinitrate patch. Despite treatment the vision continued to be no perception of light. Systemic investigations were unremarkable. Color Doppler of carotid arteries showed plaque in left carotid bulb and thrombus in right internal carotid artery. Bilateral simultaneous CRAO following head trauma has not been reported earlier. Thorough ocular examination is recommended in all cases of head injury.

    In this experiment, we tested whether perceptually delineating the scotoma location and border with a gaze contingent polygon overlay improves reading speed and reading eye movements in patients with bilateral central scotomas. Eight patients with age-related macular degeneration and bilateral central scotomas read aloud MNRead style sentences with their preferred eye. Eye movement signals from an EyeLink II eyetracker were used to create a gaze contingent display in which a polygon overlay delineating the area of the patient's scotoma was superimposed on the text during 18 of the 42 trials. Blocks of six trials with the superimposed polygon were alternated with blocks of six trials without the polygon. Reading speed and reading eye movements were assessed before and after the subjects practiced reading with the polygon overlay. All of the subjects but one showed an increase in reading speed. A paired-samples t-test for the group as a whole revealed a statistically significant increase in reading speed of 0.075 ± 0.060 (SD) log wpm after reading with the superimposed polygon. Individual subjects demonstrated significant changes in reading eye movements, with the greatest number of subjects demonstrating a shift in the average vertical fixation locus. Across subjects, there was no significant difference between the initial and final reading eye movements in terms of saccades per second, average fixation duration, average amplitude of saccades, or proportion of non-horizontal saccades. The improvement in reading speed (0.075 log wpm or 19%) over the short experimental session for the majority of subjects indicates that making the scotoma location more visible is potentially beneficial for improving reading speed in patients with bilateral central scotomas. Additional research to examine the efficacy of more extended training with this paradigm is warranted.

    Uncommon developmental abnormalities such as fused or geminated teeth are of interest for the clinical problems associated with them. A rare case of fusion between maxillary primary central and lateral incisors and a supplemental incisor occurring bilaterally is presented. The patient was a 4-year-old Thai boy. Intraoral examination revealed an abscess and fistula in the region of the fused teeth as a result of periapical osteolysis. Access cavities were prepared as acute procedures. Because of the unpromising prognosis, surgical removal of the teeth was inevitable. For functional, esthetic, and phonetic rehabilitation, an acrylic denture was incorporated.

    To report a case of bilateral idiopathic corneal keloid. Retrospective review of clinical features, histopathological findings, clinical management, and outcome. A 2-year-old boy with bilateral corneal keloid was treated with lamellar keratoplasty and tranilast eye drops. Peripheral localized white corneal nodules had been present bilaterally since the age of approximately 6 months in the absence of any history of trauma, inflammatory disease, or relevant family history. Pathological examination of the excised corneal buttons revealed myofibroblast proliferation (positive staining for α-smooth muscle actins), a haphazard arrangement of collagen bundles, and the absence of inflammatory cells. On the basis of these findings, a diagnosis of corneal keloid was assigned. The size of the corneal lesion in the right eye decreased in response to therapy with tranilast eye drops. Lamellar keratoplasty resulted in improved bilateral visual acuity, which was maintained at the 12-year follow-up. This report describes a very rare case of bilateral corneal keloid in the absence of trauma or inflammation that was diagnosed by histological and immunohistochemical examination and electron microscopy. Good visual acuity was maintained over an extended period of postsurgery follow-up. Tranilast may represent a novel adjuvant therapy for corneal keloid.

    Central serous chorioretinopathy is a common retinopathy, which is manifested by the idiopathic detachment of the neurosensory retina in the posterior pole, secondary to fluid leakage from choroidal vessels at the level of retinal pigment epithelium. The disease is typically unilateral and affects young men. We present a case of a 48-year old man, admitted to the Department of Vitreo-Retinal Surgery, Medical University in Lublin, reporting vision impairment in his right eye. The bilateral ocular exam followed by optical coherence tomography, ultra-widefield fluorescein angiography and microperimetry revealed bilateral central serous chorioretinopathy. This case presents a bilateral manifestation of central serous chorioretinopathy and emphasizes the role of advanced diagnostic imaging techniques in analyzing retinal function and disease management.

    Adrenal hemorrhage is a largely uncommon condition typically caused by a number of factors including infection, MI, CHF, anticoagulants, trauma, surgery, and antiphospholipid syndrome. Yet, idiopathic bilateral hemorrhage is rare. The authors present a case of a 63-year-old male who presented with abdominal pain that was eventually diagnosed as bilateral adrenal hemorrhages due to an unknown origin. Abdominal CT revealed normal adrenal glands without enlargement, but an MRI displayed enlargement due to hemorrhage in both adrenals. There was no known cause; the patient had not suffered from an acute infection and was not on anticoagulants, and the patient's history did not reveal any of the other known causative factors. The case underscores the importance of keeping bilateral adrenal hemorrhages on the list of differentials even when a cause is not immediately clear. It also raises the question of whether CT is the most sensitive test in the diagnosis of adrenal hemorrhage and whether the diagnostic approach should place greater weight on MRI. The case highlights the need for prompt therapy with steroids once bilateral hemorrhage is suspected to avert the development or progression of adrenal insufficiency. PMID:25973281

    Idiopathic inflammatory-demyelinating diseases (IIDDs) include a broad spectrum of central nervous system disorders that can usually be differentiated on the basis of clinical, imaging, laboratory and pathological findings. However, there can be a considerable overlap between at least some of these disorders, leading to misdiagnoses or diagnostic uncertainty. The relapsing-remitting and secondary progressive forms of multiple sclerosis (MS) are the most common IIDDs. Other MS phenotypes include those with a progressive course from onset (primary progressive and progressive relapsing) or with a benign course continuing for years after onset (benign MS). Uncommon forms of IIDDs can be classified clinically into: (1) fulminant or acute IIDDs, such as the Marburg variant of MS, Baló's concentric sclerosis, Schilder's disease, and acute disseminated encephalomyelitis; (2) monosymptomatic IIDDs, such as those involving the spinal cord (transverse myelitis), optic nerve (optic neuritis) or brainstem and cerebellum; and (3) IIDDs with a restricted topographical distribution, including Devic's neuromyelitis optica, recurrent optic neuritis and relapsing transverse myelitis. Other forms of IIDD, which are classified clinically and radiologically as pseudotumoral, can have different forms of presentation and clinical courses. Although some of these uncommon IIDDs are variants of MS, others probably correspond to different entities. MR imaging of the brain and spine is the imaging technique of choice for diagnosing these disorders, and together with the clinical and laboratory findings can accurately classify them. Precise classification of these disorders may have relevant prognostic and treatment implications, and might be helpful in distinguishing them from tumoral or infectious lesions, avoiding unnecessary aggressive diagnostic or therapeutic procedures.

    Juvenile idiopathic arthritis (JIA) is an exclusion diagnosis that gathers together all forms of arthritis that begin before the age of 16 years, persist for more than 6 weeks and are of unknown origin. We present the case of a 42 year old woman with a 20 year history of absolute trismus, secondary to bilateral temporomandibular joint (TMJ) ankylosis caused by JIA. The trismus resulted in grossly compromised oral hygiene and limited the patient to a semi-solid diet. JIA also affected her neck leading to a severe cervico-thoracic kyphosis. The patient who had been wheelchair bound developed severe lymphoedema of both lower limbs, complicating the pre-operative work up further. This particularly challenging case required input from specialists in anaesthetics, neurosurgery, special care dentistry, intensive care and maxillofacial surgery. Treatment consisted of ankylosis release, dental clearance and bilateral alloplastic replacement of her TMJs with custom implants. A full range of hinge movement and good functional outcome was achieved. This case presents the multidisciplinary approach to a severely compromised patient and illustrates the pre-, intra- and postoperative management of bilateral TMJ ankylosis with bespoke implants.

    To identify the cause of a sudden binocular vision decrease in patients with retinitis pigmentosa and bilateral idiopathic demyelinating optic neuritis is difficult, but early diagnosis and treatment significantly improve the prognosis. Here, we report a 6-year-old boy with a progressive binocular vision decrease in 38 days. The patient had a history of night blindness, a mottled retina without pigmentation, extinguished electroretinographic response, tritanopia, and an absent ellipsoid zone outside the macula fovea by optical coherence tomography in both eyes. His condition was diagnosed as retinitis pigmentosa (RP) with idiopathic demyelinating optic neuritis (IDON). After corticosteroid therapy, visual acuity recovered to OD: 0.5 and OS: 0.4. Genetic analysis revealed a G985S variant in the oral-facial-digital syndrome 1 gene. Ophthalmologists should pay attention to the existence of other complications in patients with RP who suffer a sudden decrease in vision. A gene survey can help clarify this diagnosis. To our knowledge, this is the first report of a patient with RP and ON, as well as genetic testing results. Nevertheless, the pathogenicity of the variant needs further confirmation. PMID:28191358

    The aetiology of sudden hearing loss is poorly defined; however, infectious, vascular and neoplastic aetiologies are presumed to be responsible. In addition, the aetiology of bilateral sudden hearing loss is also unknown. The objective of this study is identify the characteristics and treatment response of simultaneous bilateral sudden hearing loss. This is a case-control study that practised in tertiary care academic centre. 132 patients with sudden hearing loss who were treated with systemic steroid and hyperbaric oxygen together were included. 26 patients had bilateral sudden hearing loss and 106 patients had unilateral sudden hearing loss. Patients were evaluated with clinical, audiological and radiological examinations and laboratory tests were done. Findings and response to treatment of the patients were compared. The mean ages of patients with unilateral and bilateral sudden hearing loss were 42.0 years and 24.5 years respectively with a statistically significant difference (p<0.001). Immune response markers were more prevalent in bilateral sudden hearing loss. Pre-treatment audiologic thresholds were 69.1dB for unilateral sudden hearing loss and 63.3dB for the left ears and 67.6dB for the right ears for bilateral sudden hearing loss without significant difference. Post-treatment average hearing threshold in unilateral sudden hearing loss was 47.0dB and 55.4dB for the left ears and 59.0 for the right ears in bilateral sudden hearing loss. Average hearing improvement in unilateral sudden hearing loss group was significant (p<0.001) in spite of it was not significant in bilateral sudden hearing loss group for both ears. Between the groups; there was a significant difference for hearing improvement favouring unilateral sudden hearing loss (p<0.001). Tinnitus scores decreased significantly in both groups of patients (p<0.001) in spite of there was no significant difference between the groups of patients. Patients with bilateral sudden hearing loss showed lower

    Central diabetes insipidus is a rare clinical condition with a heterogenous aetiology. Up to 40% of cases are classified as idiopathic, although many of these are thought to have an autoimmune basis. Published data have suggested that anterior hypopituitarism is common in childhood-onset idiopathic diabetes insipidus. We aimed to assess the incidence of anterior hypopituitarism in a cohort of adult patients with idiopathic diabetes insipidus. We performed a retrospective review of the databases of two pituitary investigation units. This identified 39 patients with idiopathic diabetes insipidus. All had undergone magnetic resonance imaging scanning and dynamic pituitary testing (either insulin tolerance testing or GHRH/arginine and short synacthen testing) to assess anterior pituitary function. One patient had partial growth hormone deficiency; no other anterior pituitary hormonal deficits were found. Thirty-three percent had at least one autoimmune disease in addition to central diabetes insipidus. Our data suggest that anterior hypopituitarism is rare in adult idiopathic diabetes insipidus. Routine screening of these patients for anterior hypopituitarism may not, therefore, be indicated. The significant prevalence of autoimmune disease in this cohort supports the hypothesis that idiopathic diabetes insipidus may have an autoimmune aetiology. © 2012 Blackwell Publishing Ltd.

    A previously healthy 27-year-old Malay male presented with acute onset of painless, severe blurring of vision in his right eye. It was associated with headache and vomiting for the past week. Relative afferent pupillary defect was present in the right eye, with reduced optic nerve function. Patient also had bilateral generalised optic disc swelling, splinter haemorrhages, and tortuous vessels. Initial examination was suggestive of either optic neuritis or raised intracranial pressure. Typical features of bilateral optic perineuritis (OPN) such as tram track and doughnut sign were observed on magnetic resonance imaging. Connective tissue and infective screening were negative. He was diagnosed with bilateral optic perineuritis and treated with high dose intravenous corticosteroids followed by a three-month course of oral steroids. His vision and optic nerve function recovered to baseline levels. PMID:28078151

    The detection of anomalous extra-spinal left-right skeletal length asymmetries in the upper limbs, periapical ribs, ilia and lower limbs of subjects with adolescent idiopathic scoliosis (AIS) raises questions about skeletal bilateral symmetry of vertebrates in health and disorder, its origin and control. The vertebrate body plan externally has mirror-image bilateral symmetries that are highly conserved culminating in the adult form. The normal human body can be viewed as containing paired skeletal structures in the axial and appendicular skeleton as 1) separate left and right paired forms (eg long limb bones, ribs, ilia), and 2) united in paired forms (eg vertebrae, sternum, skull, mandible). Each of these separate and united pairs are mirror-image forms--enantiomorphs. Left-right asymmetries of growth plates (physes) may cause (1) in long bones length asymmetries, (2) within one or more vertebral physes putative growth conflict with distortion as deformity, and (3) between ribs and vertebrae putative growth conflict that triggers thoracic AIS suggesting preventive surgery on spine and ribs. There is evidence of a possible role for environmental factors in AIS development. Genes and the environment (nature/nurture) may interact pre- and/or post-natally to explain both the deformity of AIS and its association with widespread anomalous skeletal length asymmetries. If substantiated there may ultimately be a place for the prevention of AIS in some subjects.

    The authors present the management of a young female patient who presented with longstanding bilateral calf muscle hypertrophy, with no known cause. Taking into account the patient's wishes and the fact that the hypertrophy was mainly located in the posteromedial compartment, we chose to carry out a subtotal bilateral resection of medial gastrocnemius muscles. This procedure was performed with an harmonic scalpel, permitting a excellent cosmetic result while avoiding complications or functional impairment. After a reviewing of the commonly used techniques, the authors discuss the chosen surgical approach taking into account its clinical particularity. Copyright © 2014 Elsevier Masson SAS.

    Paroxysmal kinesigenic dyskinesia (PKD) is presented as a short paroxysmal attack of focal or generalized involuntary movement. Bilateral striopallidodentate calcinosis (BSPDC) is referred to as Fahr's disease and is characterized by the calcification of the basal ganglia, cerebellar nuclei and thalamus. Most common presentation of BSPDC was a parkinsonism, and PKD has also been reported to few of the cases with sporadic BSPDC. Here, we report the case of a 35-year-old-man with PKD for 19 years, and we describe the pathogenesis of PKD in the BSPDC.

    Objective The purpose of this case report is to describe a patient with bilateral idiopathic osteonecrosis of the femoral head (ONFH), provide a discussion of differential diagnosis for anterior hip pain, imaging, and treatment recommendations for ONFH. Clinical features A 34-year-old man was initially treated by a chiropractic physician for low back pain. At the end of a three week trial of care, the patient’s low back pain resolved. However, he reported a new complaint of mild left anterior hip stiffness. After re-examination, a homecare exercise program was prescribed. The patient returned 1 month later with substantial left anterior hip pain and walked with a noticeable limp. Radiography of the left hip demonstrated advanced ONFH. Magnetic resonance imaging of both hips demonstrated the extent of involvement of the left hip while incidentally revealing ONFH on the right. Intervention and Outcome A total hip arthroplasty was performed on the left hip and the right hip is being monitored without intervention. Conclusion Osteonecrosis of the femoral head is a challenging clinical problem with non-specific and wide-ranging signs and symptoms requiring clinicians to engage a cautious and comprehensive differential diagnosis. Prompt recognition ensures that appropriate treatment can be initiated in a timely manner and optimal patient outcomes achieved. PMID:25225469

    2016-01-01

    The pathophysiological mechanisms underlying overactive bladder syndrome (OAB) can include dysfunction of sensory pathways of the peripheral and central nervous systems, resulting in bladder hypersensitivity. Central sensitization describes an induced state of spinal hypersensitivity that is associated with a variety of chronic pain disorders that share many attributes with OAB, albeit without the presence of pain. As such, the concept of central sensitization might be relevant to understanding the mechanisms and clinical manifestations of OAB syndrome. An understanding of the pathophysiology and clinical manifestations of central sensitization, and the evidence that supports a role of central sensitization in OAB, including the potential implications of mechanisms of central sensitization for the treatment of patients with OAB could provide a novel approach to the treatment of patients with this disease. Such an approach would be especially relevant to those patients with central sensitization-related comorbidities, and has the potential to improve the outcomes of these patients in particular.

    Chronic neck pain is a common problem with a poorly understood pathophysiology. Often no underlying structural pathology can be found and radiological imaging findings are more related to age than to a patient's symptoms. Besides its common occurrence, chronic idiopathic neck pain is also very disabling with almost 50% of all neck pain patients showing moderate disability at long-term follow-up. Central sensitization (CS) is defined as "an amplification of neural signaling within the central nervous system that elicits pain hypersensitivity," "increased responsiveness of nociceptive neurons in the central nervous system to their normal or subthreshold afferent input," or "an augmentation of responsiveness of central neurons to input from unimodal and polymodal receptors." There is increasing evidence for involvement of CS in many chronic pain conditions. Within the area of chronic idiopathic neck pain, there is consistent evidence for the presence and clinical importance of CS in patients with traumatic neck pain, or whiplash-associated disorders. However, the majority of chronic idiopathic neck pain patients are unrelated to a traumatic injury, and hence are termed chronic idiopathic non-traumatic neck pain. When comparing whiplash with idiopathic non-traumatic neck pain, indications for different underlying mechanisms are found. The goal of this article was to review the existing scientific literature on the role of CS in patients with chronic idiopathic non-traumatic neck pain. Systematic review. All selected studies were case control studies. A systematic search of existing, relevant literature was performed via the electronic databases Medline, Embase, Web of Science, Cinahl, PubMed, and Google Scholar. All titles and abstracts were checked to identify relevant articles.

    Pediatric cohorts of central diabetes insipidus (CDI) have shown varying prevalences for the different causes of CDI, including idiopathic. The objective of the study was to determine the causes of CDI at a pediatric tertiary care center and to characterize their clinical outcomes. All patients with CDI at Seattle Children's Hospital were identified and retrospectively analyzed. From 2000 to 2013, 147 patients with CDI were encountered (mean age 7 y at diagnosis, mean follow-up 6.2 y). The different causes of CDI were grouped, and age of diagnosis, anterior pituitary hormone deficiencies (APHDs), and presence of the posterior pituitary bright spot (PPBS) were analyzed. Patients with idiopathic CDI had infundibular thickening measured using a systematic method. Brain malformations caused 24% of CDI cases, and 12.2% were idiopathic. Four of 22 patients with initially idiopathic CDI were diagnosed with an underlying condition, none occurring later than 2.5 years from diagnosis. APHDs were as common in the brain malformation group as they were in the tumor/infiltrative group (72% vs 85%; P = .09). The PPBS was present in at least 13% of patients and in 19% of those with brain malformations. Patients with idiopathic CDI and stalk thickening on the initial magnetic resonance imaging were more likely to have an underlying diagnosis (40% vs 0%; P = .03). Brain malformations were a more common cause of pediatric CDI than previously reported. These patients have a high rate of APHDs, and many have persistence of the PPBS. Idiopathic CDI is an uncommon diagnosis, and none of our patients were diagnosed with Langerhans cell histiocytosis or germinoma for more than 3 years from CDI diagnosis. Providers can consider less frequent magnetic resonance imaging after this time point. A systematic method of infundibular measurement on the initial magnetic resonance imaging may predict an underlying germinoma or Langerhans cell histiocytosis.

    Central venous stenosis (CVS) in hemodialysis patients could be secondary to central venous catheterization, high flow arteriovenous fistula, as well as extrinsic compression. However, we report a senile hemodialysis patient of left internal jugular vein stenosis and right innominate vein occlusion unrelated to any known risk factors. Aided by computed tomography and digital subtraction angiography, we managed to dilate the stenosis by percutaneous balloon angioplasty, followed by successful tunneled catheter placement. Nephrologists should be aware of idiopathic CVS and its impact on the creation and preservation of vascular access. When confronted with difficulties in catheter placement, practitioners need to consider the possibilities of idiopathic CVS and refer to radiological tests. © 2013 International Society for Hemodialysis.

    Background Single-lung transplantation (SLT) and bilateral lung transplantation (BLT) are both good options for patients with end-stage lung disease secondary to idiopathic pulmonary fibrosis. It is, however, unclear whether BLT offers any survival advantage over SLT. The purpose of our study was to evaluate a large group of patients to determine if either SLT or BLT officered a long-term survival advantage for patients with IPF. Methods This was an Institutional Review Board-approved retrospective analysis of the United Network of Organ Sharing database from 1987 to 2008. Survival was determined using Kaplan-Meir estimates and the effect of laterality was determined by Cox proportional hazards and propensity analyses. Results Lung transplantation for idiopathic pulmonary fibrosis was performed in 3,860 patients (2,431 SLTs and 1429 BLTs). Multivariate and propensity analysis failed to show any survival advantage for BLT (hazard ratio = 0.90, 95% confidence interval = 0.78 to 1.0, p = 0.11). One-year conditional survival favored BLT (hazard ratio 0.73, 95% confidence interval 0.60 to 0.87, p = 0.00064). Risk factors for early death included recipient age over 57 and donor age over 36 years. Conclusions Bilateral lung transplantation should be considered for younger patients with idiopathic pulmonary fibrosis and results may be optimized when younger donors are used. PMID:21172522

    Bilateral, simultaneous optic nerve sheath infiltration as a manifestation of leukemia relapse is very rare. A 45-year-old woman with chronic myelogenous leukemia was successfully treated to cytogenetic bone marrow remission 1 year previously and maintained on imatinib. She developed total bilateral blindness with marked, bilateral optic disc edema and evidence of bilateral optic nerve infiltration on magnetic resonance imaging. Cerebrospinal fluid cytology confirmed central nervous system (CNS) blast crisis. She recovered visual acuity of 20/20 in the right eye, and 20/25 in the left eye with salvage systemic and intrathecal chemotherapy before radiation therapy. Our report underscores the importance of timely and aggressive intervention of blast crisis of the CNS and the need for CNS penetrating induction and maintenance therapy.

    Etiologies for diffuse alveolar hemorrhage are wide and range from infectious to vasculitis and malignant processes. Idiopathic thrombocytopenic purpura is an autoimmune disorder characterized by persistent thrombocytopenia, with a relatively indolent course in young patients, but a more complicated progression and high associated mortality in the older patients. Diffuse alveolar hemorrhage, complicating idiopathic thrombocytopenic purpura, is a very uncommon association, with only 2 reported cases in the literature. We present a 69-year-old healthy woman presenting with petechial rash, progressive dyspnea, and bilateral alveolar infiltrates. She was found to have idiopathic thrombocytopenic purpura associated with diffuse alveolar hemorrhage. The patient had an excellent response to high doses of pulse steroids and immunoglobulins. A high index of suspicion for noninfectious pulmonary diseases should be considered in patients with autoimmune diseases presenting with pulmonary infiltrates and hypoxia. Flexible bronchoscopy with sequential lavage is a relatively safe procedure in patients with coagulopathy and should be attempted to detect and confirm the diagnosis; absence of hemoptysis should not preclude the diagnosis.

    The aim of this study was to investigate whether bilateral widespread pressure hypersensitivity exists in patients with unilateral carpal tunnel syndrome. A total of 20 females with carpal tunnel syndrome (aged 22-60 years), and 20 healthy matched females (aged 21-60 years old) were recruited. Pressure pain thresholds were assessed bilaterally over median, ulnar, and radial nerve trunks, the C5-C6 zygapophyseal joint, the carpal tunnel and the tibialis anterior muscle in a blinded design. The results showed that pressure pain threshold levels were significantly decreased bilaterally over the median, ulnar, and radial nerve trunks, the carpal tunnel, the C5-C6 zygapophyseal joint, and the tibialis anterior muscle in patients with unilateral carpal tunnel syndrome as compared to healthy controls (all, P < 0.001). Pressure pain threshold was negatively correlated to both hand pain intensity and duration of symptoms (all, P < 0.001). Our findings revealed bilateral widespread pressure hypersensitivity in subjects with carpal tunnel syndrome, which suggest that widespread central sensitization is involved in patients with unilateral carpal tunnel syndrome. The generalized decrease in pressure pain thresholds associated with pain intensity and duration of symptoms supports a role of the peripheral drive to initiate and maintain central sensitization. Nevertheless, both central and peripheral sensitization mechanisms are probably involved at the same time in carpal tunnel syndrome.

    Central retinal vein occlusion (CRVO) is a common pathology of the retinal vasculature. Patients with CRVO usually present with a drop in visual acuity. The condition bears no specific therapy; treatment is aimed at the management of potentially blinding complications, of which there are many. With majority of cases being unilateral, bilateral CRVO is usually associated with an underlying systemic illness such as a hyperviscosity syndrome. Here, we present a case of a patient, who presented with a bilateral drop in vision diagnosed as bilateral CRVO on ophthalmic evaluation. Systemic workup revealed the presence of an underlying undiagnosed chronic myeloid leukemia. An initial presentation to the ophthalmologist is a rare occurrence in leukemic patients. This case report highlights the role of the ophthalmologist in diagnosing a potentially life-threatening hematological illness.

    Diabetes insipidus (DI) is a condition with heterogeneous clinical symptoms characterized by polyuria (urine output >4 mL/kg/hr) and polydipsia (water intake >2 L/m (2)/d). In children, acquired nephrogenic DI (NDI) is more common than central DI (CDI). Diagnosis is based on the presence of high plasma osmolality and low urinary osmolality with significant water diuresis. A water deprivation test with vasopressin challenge, though has limitations, is done to differentiate NDI from CDI and diagnose their incomplete forms. Neonates and young infants are better managed with hydration therapy alone. Older children with CDI are treated with desmopressin (1-deamino-8-D-arginine vasopressin, dDAVP). Its oral form is safe, highly effective and has dosing flexibility. We report a case of an 8-year-old male patient with CDI with severe bilateral non-obstructive hydronephrosis and megaureter. Dramatic clinical and radiological responses to dDAVP treatment were achieved and therapy reduced urine volume and led to marked radiological improvement in hydronephrosis.

    To investigate bilateral widespread pressure pain hyperalgesia in deep tissues over symptomatic (trigemino-cervical) and nonsymptomatic (distant pain-free) regions in patients with cluster headache (CH). Central sensitization is claimed to play a relevant role in CH. No study has previously searched for widespread pressure hyperalgesia in deep tissues over both symptomatic (trigemino-cervical) and nonsymptomatic (distant pain-free) regions in patients with CH. Sixteen men (mean age: 43 ± 11 years) with CH in a remission phase and 16 matched controls were recruited. Pressure pain thresholds (PPTs) were bilaterally measured over the supra-orbital (V1), infra-orbital (V2), mental (V3), median (C5), radial (C6), and ulnar (C7) nerves, C5-C6 zygapophyseal joint, mastoid process, and tibialis anterior muscle by an assessor blinded to the subjects' condition. The results showed that PPT levels were significantly decreased bilaterally in patients with CH as compared with healthy controls (all sites, P < .001). A greater degree of sensitization over the mastoid process (P < .001) and a lower degree of sensitization over the tibialis anterior muscle (P < .01) was found. Our findings revealed bilateral widespread pressure pain hypersensitivity in patients with CH confirming the presence of central sensitization mechanisms in this headache condition. © 2010 American Headache Society.

    Neonatal central diabetes insipidus (DI) is an extremely rare disorder that can cause severe morbidity and mortality. We have reported a very low birth weight infant with idiopathic central DI presenting in the first month of life who was successfully treated with sublingual desmopressin therapy. In this report, we emphasize that central DI should be kept in mind in an infant with unexplained hypernatremia and polyuria. Timely diagnosis and treatment with lyophilized desmopressin may prevent severe morbidity and mortality.

    The case is presented on a 54-year-old woman with a central serous chorioretinopathy, misdiagnosed as Vogt-Koyanagi-Harada disease, and treated with systemic corticosteroids. The patient presented with a bilateral bullous exudative retinal detachment. Discontinuation of corticosteroid therapy, surgical drainage of subretinal fluid, and photodynamic therapy, led to anatomical and functional improvement. The recognition of an atypical presentation of central serous chorioretinopathy may avoid complications of the inappropriate treatment with corticosteroids.

    Purpose To report a case of bilateral bullous exudative retinal detachment in central serous chorioretinopathy (CSC) which was attached by vitrectomy and internal drainage of the subretinal fluid. Methods A 47-year-old man affected by bilateral atypical CSC with a bullous retinal detachment with subretinal exudate. A fluorescein angiogram (FAG) showed multiple points of leakage and staining of subretinal fibrosis. A tentative diagnosis of Vogt-Koyanagi-Harada (VKH) syndrome was made and the patient was treated with systemic corticosteroids and immunosuppressive agents. However, the subretinal fluid was not absorbed. He was then treated with vitrectomy and internal drainage of subretinal fluid. Results The retina was attached successfully in both eyes. Visual acuity improved to 20/50 in his left eye but did not improve in the right eye due to subretinal fibrotic scarring and atropic changes on the macula. Conclusions Our case suggests that the surgical management of bullous exudative retinal detachment is safe and necessary. PMID:16892652

    Subjects with bilateral central vision loss (CVL) use a retinal region called the preferred retinal locus (PRL) for performing various visual tasks. We probed the fixation PRL in individuals with bilateral macular disease, including age-related macular degeneration (AMD) and Stargardt disease (STGD), for localized sensitivity deficits. Three letter words at the critical print size were presented in the NIDEK MP-1 microperimeter to determine the fixation PRL and its radial retinal eccentricity from the residual fovea in 29 subjects with bilateral CVL. Fixation stability was defined as the median bivariate contour ellipse area (BCEA) from 3 fixation assessments. A standard 10-2 grid (68 locations, 2° apart) was used to determine central retinal sensitivity for Goldmann size II test spots. Baseline and follow-up supra-threshold screening of the fixation PRL for localized sensitivity deficits was performed using high density (0.2° or 0.3° apart) 0 dB Goldmann size II test spots. Custom MATLAB code and a dual bootstrapping algorithm were used to register test-spot locations from the baseline and follow-up tests. Locations where the 0 dB test spots were not seen on either test were labeled as micro-scotomas (MSs). Median BCEA correlated poorly with the radial eccentricity of the fixation PRL. Mean (±SD) sensitivity around the PRL from 10-2 testing was 4.93 ± 4.73 dB. The average percentage of MSs was similar for patients with AMD (25.4%), STGD (20.3%), and other etiologies of CVL (27.1%). The fixation PRL in subjects with bilateral CVL frequently includes local regions of sensitivity loss.

    Idiopathic hypogonadotropic hypogonadism is a rare disease that is characterized by delayed/absent puberty and/or infertility due to an insufficient stimulation of an otherwise normal pituitary–gonadal axis by gonadotrophin-releasing hormone (GnRH) action. Because reduced or normal luteinizing hormone (LH)/follicle-stimulating hormone (FSH) levels may be observed in the affected patients, the term idiopathic central hypogonadism (ICH) appears to be more appropriate. This disease should be distinguished from central hypogonadism that is combined with other pituitary deficiencies. Isolated ICH has a complex pathogenesis and is fivefold more prevalent in males. ICH frequently appears in a sporadic form, but several familial cases have also been reported. This finding, in conjunction with the description of numerous pathogenetic gene variants and the generation of several knockout models, supports the existence of a strong genetic component. ICH may be associated with several morphogenetic abnormalities, which include osmic defects that, with ICH, constitute the cardinal manifestations of Kallmann syndrome (KS). KS accounts for approximately 40% of the total ICH cases and has been generally considered to be a distinct subgroup. However, the description of several pedigrees, which include relatives who are affected either with isolated osmic defects, KS, or normo-osmic ICH (nICH), justifies the emerging idea that ICH is a complex genetic disease that is characterized by variable expressivity and penetrance. In this context, either multiple gene variants or environmental factors and epigenetic modifications may contribute to the variable disease manifestations. We review the genetic mechanisms that are presently known to be involved in ICH pathogenesis and provide a clinical overview of the 227 cases that have been collected by the collaborating centres of the Italian ICH Network.

    A 39-year old man came to our outpatient clinic with long history of unspecific symptoms and signs. Cerebral MRI showed herniation of the cerebellar tonsils of more than 1 cm below the foramen magnum and a triventricular hydrocephalus. A diagnosis of Chiari I malformation was retained. After an osteo-dural decompression of the posterior fossa, post-operative MRI revealed an aqueductal stenosis with triventricular hydrocephalus. An endoscopic-third- ventriculostomy showed an idiopathic stenosis of the right foramen of Monro. Residual symptoms and persistence of biventricular hydrocephalus justified a ventriculo-peritoneal shunt. Aqueductal and foramina of Monro stenosis can mimick a Chiari I malformation.

    Aim To investigate the presence of variants in the TAC3 and TACR3 genes, which encode NKB and its receptor (NK3R), respectively, in a large cohort of patients with idiopathic central pubertal disorders. Patients and Methods Two hundred and thirty seven patients were studied: 114 with central precocious puberty (CPP), 73 with normosmic isolated hypogonadotropic hypogonadism (IHH) and 50 with constitutional delay of growth and puberty (CDGP). The control group consisted of 150 Brazilian individuals with normal pubertal development. Genomic DNA was extracted from peripheral blood and the entire coding region of both TAC3 and TACR3 genes were amplified and automatically sequenced. Results We identified one variant (p.A63P) in NKB and four variants, p.G18D, p.L58L (c.172C>T), p.W275* and p.A449S in NK3R, which were absent in the control group. The p.A63P variant was identified in a girl with CPP, and p.A449S in a girl with CDGP. The known p.G18D, p.L58L and p.W275* variants were identified in three unrelated males with normosmic IHH. Conclusion Rare variants in the TAC3 and TACR3 genes were identified in patients with central pubertal disorders. Loss-of-function variants of TACR3 were associated with the normosmic IHH phenotype.

    Blood pressure is commonly abnormal in parkinsonian disorders, but central hemodynamics and arterial stiffness, well-established predictors of total cardiovascular risk, have rarely been studied in these disorders. 32 patients [27 with idiopathic Parkinson's disease (iPD); 5 with multiple system atrophy (MSA)] and 15 controls matched for cardiac risk factors underwent 24 h-ambulatory blood pressure recordings using an I.E.M. device (Mobil-O-Graph™), measuring peripheral pressure and calculating central pressures and arterial stiffness. Mean augmentation indices corrected for heart rate (AIx@75) were significantly lower and pulse wave velocities were significantly elevated in patients compared to controls. Central systolic blood pressure, cardiac output and daytime total vascular resistance were significantly elevated in patients. Mean nocturnal systolic peripheral blood pressure and nocturnal heart rates were also significantly higher; 56.3% of patients had nocturnal hypertension (80% of the MSA group); 85.2% showed non-dipping. This supports previous findings of reduced vulnerability to systemic atherosclerosis and end-organ damage in treated PD. Yet, hemodynamic abnormalities were common and often remained asymptomatic.

    We report the case of a patient with Cushing disease revealed by bilateral central serous chorioretinopathy (CSCR). We present the clinical history, physical findings, laboratory results, and imaging studies of a 53-year-old Chinese woman with a Cushing disease revealed by bilateral CSCR. The association with CSCR and the pertinent literature are reviewed. A 53-year-old patient initially presented to the Department of Ophthalmology with a 4-week history of decreased vision in the left eye. Standard ophthalmologic examination and fluorescein angiography established the diagnosis of bilateral CSCR. Systemic clinical signs and biochemical analysis indicated hypercortisolism. Magnetic resonance imaging (MRI) of the pituitary gland showed a left-side lesion compatible with a microadenoma. The diagnosis of Adrenocorticotropic hormone (ACTH)-dependent Cushing syndrome secondary to a pituitary microadenoma was selected. Endoscopic endonasal transsphenoidal surgery was performed and the pituitary adenoma was successfully removed. The histology confirmed the presence of ACTH-immunopositive pituitary adenoma. Early postoperative morning cortisol levels indicated early remission. At 6 weeks postoperatively, the patient's morning cortisol remains undetectable, and serous retinal detachments had regressed. CSCR is an uncommon manifestation of endogenous Cushing syndrome. It can be the first presentation of hypercortisolism caused by Cushing disease. CSCR should be considered when assessing patients with Cushing syndrome complaining of visual disorders. On the other hand, it is useful in patients with an atypical form of CSCR to exclude Cushing's syndrome.

    To report a case of primary angiitis of the central nervous system (PACNS), a rare inflammatory disease restricted to the central nervous system (CNS), with unusual clinical presentation mimicking schizophrenia. Case report. A 45-year-old male presented with alteration of consciousness and confusion. Brain magnetic resonance imaging (MRI) scan showed a mass-like enhancing lesion involving bilateral thalami, and biopsy revealed findings compatible with PACNS. The patient was treated with corticosteroids. Psychotic symptoms crystallized over the initial 2 months after the diagnosis and persisted for over a year. Severity of his symptoms improved with gradual normalization of the radiologic findings and antipsychotic medication. Our case highlights the importance of considering PACNS as a differential diagnosis of a tumor-like mass lesion in the CNS and the significance of thalamic involvement in the pathogenesis of psychotic symptoms including delusions and hallucinations.

    Background Widely used rod rotation and translation techniques for idiopathic scoliosis (IS) are effective in correcting spinal coronal deformity. Bilateral apical vertebral derotation technique by vertebral column manipulation (VCM) and vertebral coplanar alignment (VCA) technique are two strategies for three-dimensional (3D) correction for IS. The purpose of this study is to compare the post-surgical results and technical features of the bilateral apical vertebral derotation technique by VCM against the VCA technique in patients with Lenke type 1 IS. Methods Forty-eight patients with Lenke type 1 IS were enrolled in the present prospective clinical assay. They were divided into groups A (bilateral apical vertebral derotation technique by VCM, n=24) and B (VCA technique, n=24). Radiographic parameters measured before and after surgery included the Cobb angle, thoracic kyphosis, and apical vertebral rotation. Scoliosis Research Society (SRS)-22 scores were evaluated during the final follow-up. The differences in the demographics, surgical details, and radiographic measurements between the two groups were determined using a T test. The Mann–Whitney U test was used to evaluate the differences in the SRS-22 scores. A value of P<0.05 was considered statistically significant. Results In the coronal plane, a significant difference was found in the correction rate of the major curve (group A: 84.8%, group B: 78.4%; P=0.045) and in the Cincinnati Correction Index between two groups (group A: 2.21, group B: 1.98; P=0.047). In the sagittal plane, no difference was found in the postoperative thoracic kyphosis between the two groups (P=0.328). In the transverse plane, no difference was found between the two groups in the correction rates of the rotation angle sagittal (P=0.298), rib hump (P=0.934), apical vertebral body-to-rib ratio (P=0.988), or apical rib spread difference (P=0.184). Patients underwent follow up for an average of 21.9 and 22.2 months in groups A and B

    We describe a 71-year-old-patient receiving antiplatelet therapy and being attended by emergency medical services for psychomotor retardation and gait disturbance. An emergency computed tomographic scan showed a bilateral subacute hematoma. The patient reported a fall 2 weeks earlier. We performed bilateral drills and saw a solid mass that was biopsied. The patient had a history of mantle cell lymphoma (MCL) in complete remission (results of bone marrow biopsy and whole-body positron emission tomography-computed tomography scans were normal 6 months earlier). We diagnosed an intracranial MCL by immunohistochemistry, flow cytometry, and fluorescence in situ hybridization. We performed magnetic resonance imaging. The results of a new bone marrow biopsy were positive for recurrence of MCL. MCL constitutes approximately 5%-6% of non-Hodgkin lymphoma. The incidence of central nervous system (CNS) involvement between MCLs is 4.1%. After a review of the literatures we found small series comprising 3-5 cases and a multicenter study with 57 cases. Until now, the median survival was 3.7 months. Ibrutinib, an oral Bruton tyrosine kinase inhibitor, has demonstrated efficacy and CNS penetration in relapsed or refractory MCL with rapid and complete response even after 1 year of follow-up. Our patient received ibrutinib and had a complete response at 3 months, which was maintained to the present (6 months). After a review of the literature, we found different pathologies that can mimic subdural hematomas. However, this is the first report of a lymphoma with CNS involvement mimicking bilateral subdural hematomas. This report contributes to the knowledge of lymphomas with CNS involvement. Its strange radiographic appearance and histologic type make it unique.

  11. Central Disorders of Hypersomnolence: Focus on the Narcolepsies and Idiopathic Hypersomnia.

    2015-07-01

    The central disorders of hypersomnolence are characterized by severe daytime sleepiness, which is present despite normal quality and timing of nocturnal sleep. Recent reclassification distinguishes three main subtypes: narcolepsy type 1, narcolepsy type 2, and idiopathic hypersomnia (IH), which are the focus of this review. Narcolepsy type 1 results from loss of hypothalamic hypocretin neurons, while the pathophysiology underlying narcolepsy type 2 and IH remains to be fully elucidated. Treatment of all three disorders focuses on the management of sleepiness, with additional treatment of cataplexy in those patients with narcolepsy type 1. Sleepiness can be treated with modafinil/armodafinil or sympathomimetic CNS stimulants, which have been shown to be beneficial in randomized controlled trials of narcolepsy and, quite recently, IH. In those patients with narcolepsy type 1, sodium oxybate is effective for the treatment of both sleepiness and cataplexy. Despite these treatments, there remains a subset of hypersomnolent patients with persistent sleepiness, in whom alternate therapies are needed. Emerging treatments for sleepiness include histamine H3 antagonists (eg, pitolisant) and possibly negative allosteric modulators of the gamma-aminobutyric acid-A receptor (eg, clarithromycin and flumazenil).

    The purpose of this study was to evaluate changes in subfoveal choroidal thickness after photodynamic therapy in patients with acute idiopathic central serous chorioretinopathy (ICSCR). This was a retrospective observational study conducted in 63 participants. The primary outcome measure was subfoveal choroidal thickness at baseline and 3 days, one week, 4 weeks, and 12 weeks after photodynamic therapy. The secondary outcome measure was indocyanine green angiography at baseline and 4 weeks and 12 weeks after photodynamic therapy. Four weeks after photodynamic therapy, 20 (64.51%) symptomatic eyes showed hypofluorescence corresponding to the area of photodynamic therapy irradiation at the posterior pole. The mean subfoveal choroidal thickness increased significantly from 422±132 μm at baseline to 478±163 μm at day 3 after treatment (P=0.022) and then decreased to 362±113 μm at week 4 (P<0.001) and 339±135 μm at week 12 (P<0.001). The subfoveal choroid in patients with acute ICSCR is thicker than in the normal population, and in symptomatic eyes is significantly thicker than in fellow eyes. Photodynamic therapy using a one third dose of verteporfin may decrease choroidal vascular hyperpermeability and choroidal thickness in patients with acute ICSCR.

    Spontaneous chronic subdural hematoma (CSH) in infants is extremely rare. A very limited number of cases are known and reported in literature. The clinical presentation can be myriad varying from asymptomatic cases to gross neurological deficits. We report a case of a 3-month-old child who presented to us with repeated episodes of focal seizures of the left upper and lower limb of 1 month duration. Subsequent imaging revealed bilateral CSH (right > left) with left internal carotid artery infarct and midline shift to left by 8 mm. The child improved following burr hole evacuation of the right-sided CSH. The management of such case and a brief review of literature are discussed. PMID:28217168

    Male rats received either ibotenic acid (IBO) or sham lesions bilaterally into the central or lateral amygdala or were assigned to an unoperated control group. After the postoperation recovery period all lesioned and unoperated animals were tested for open field behaviour and for the ability to master a free operant successive discrimination. Retention of the discrimination learning was evaluated 48 h later for the original and reversal problem. After the reversal learning retention test the unoperated animals were assigned at random to one unoperated control and two IBO amygdaloid lesioned groups (central and lateral) and these, unoperated and lesioned animals, received additional free operant successive discrimination retraining after the surgery recovery period. Significant lesion effects were found in the emotional indices in the open field test. The lesions significantly impaired the postoperative acquisition of a free operant successive discrimination and its reversal and diminished its retention but did not impair the retention of such a discrimination task acquired before the lesion. The contribution of central and lateral amygdala in open field behaviour and in the major components of a free operant successive discrimination is discussed. In order to know how the amygdala is involved in association of sensorial stimuli with reinforcement we suggest experimental designs controlling the detailed components of such an association.

    Microperimetry-1 (MP-1) evaluation and MP-1 biofeedback training were done in a case of bilateral myopic macular degeneration with a central scotoma. Fixation behavior, location and stability of preferred retinal locus, eye movement speed, and mean sensitivity were assessed. The mean retinal sensitivities before, after and at 1-year after training in the right eye were 2.9 dB, 2.9 dB and 3.7 dB and in the left eye were 3.5 dB, 3.7 dB and 1.8 dB. The fixation point in the 2° gravitation circle, improved from 40% to 50% in the right eye and from 43% to 67% in the left eye. The average eye speed before, after and at 1-year after training in right eye were 0.19°/s, 0.26°/s and 0.25°/s and in left eye were 0.36°/s, 0.25°/s and 0.27°/s. Thus, biofeedback training using MP-1 can improve the visual function in patients with macular diseases and central scotoma. PMID:26265646

    Ob­jec­ti­ve: Bisphenol A (BPA) is an industrial chemical, particularly used to harden plastics. BPA is thought to have negative health effects on both laboratory animals and humans. Consider ing the decline in age of onset of puberty noted in recent years, particularly among girls, the importance of BPA as an estrogenic endocrine disruptor has increased. In this study, we aimed to determine urinary BPA levels in girls with idiopathic central precocious puberty (ICPP). Methods: Non-obese girls newly diagnosed with ICPP (n=28, age 4-8 years) constituted the study group. The control group consisted of 25 healthy age-matched girls with no history of ICPP or any other endocrine disorder. Urinary BPA levels were measured by using high-performance liquid chromatography. Results: In the ICPP group, urinary BPA levels were significantly higher compared to the control group [median 8.34 (0.84-67.35) μg/g creatinine and 1.62 (0.3-25.79) μg/g creatinine, respectively (OR=8.68, 95% CI:2.03-32.72, p=0.001)]. There was no marked correlation between urinary BPA levels and body mass index in either group. In the ICPP group, no significant correlations were found between urinary BPA levels and serum luteinizing hormone, follicle-stimulating hormone and estradiol levels. Conclusions: To our knowledge, this is the first study evaluating the urinary BPA levels in Turkish girls with ICPP. Our results indicate that the estrogenic effects of BPA may be an etiologic factor in ICPP. PMID:24637305

    Malformations of cortical development (MCD) have been observed in human reading and language impaired populations. Injury-induced MCD in rodent models of reading disability show morphological changes in the auditory thalamic nucleus (medial geniculate nucleus; MGN) and auditory processing impairments, thus suggesting a link between MCD, MGN, and auditory processing behavior. Previous neuroanatomical examination of a BXD29 recombinant inbred strain (BXD29-Tlr4(lps-2J)/J) revealed MCD consisting of bilateral subcortical nodular heterotopia with partial callosal agenesis. Subsequent behavioral characterization showed a severe impairment in auditory processing-a deficient behavioral phenotype seen across both male and female BXD29-Tlr4(lps-2J)/J mice. In the present study we expanded upon the neuroanatomical findings in the BXD29-Tlr4(lps-2J)/J mutant mouse by investigating whether subcortical changes in cellular morphology are present in neural structures critical to central auditory processing (MGN, and the ventral and dorsal subdivisions of the cochlear nucleus; VCN and DCN, respectively). Stereological assessment of brain tissue of male and female BXD29-Tlr4(lps-2J)/J mice previously tested on an auditory processing battery revealed overall smaller neurons in the MGN of BXD29-Tlr4(lps-2J)/J mutant mice in comparison to BXD29/Ty coisogenic controls, regardless of sex. Interestingly, examination of the VCN and DCN revealed sexually dimorphic changes in neuronal size, with a distribution shift toward larger neurons in female BXD29-Tlr4(lps-2J)/J brains. These effects were not seen in males. Together, the combined data set supports and further expands the observed co-occurrence of MCD, auditory processing impairments, and changes in subcortical anatomy of the central auditory pathway. The current stereological findings also highlight sex differences in neuroanatomical presentation in the presence of a common auditory behavioral phenotype. Copyright © 2014 Elsevier B

    The aim of the present study was to investigate the diagnostic role of serum neurokinin B level and its relationship with kisspeptin and leptin, which are known to be involved in the initiation of pubertal process. Girls who presented with breast development (<8 years) were included in the study. All patients underwent bone age assessment. Basal levels of serum follicle stimulating hormone and luteinizing hormone were measured and gonadotropin releasing hormone stimulation test was performed. Patients with a bone age/chronological age ratio >1 and a peak luteinizing hormone response in gonadotropin releasing hormone stimulation test >5mIU/L were included in the central precocious puberty group, while patients who did not meet these criteria were included in the premature thelarche group. Patients with organic pathologies were excluded. Healthy prepubertal girls with similar age were included as the control group. Leptin, kisspeptin and neurokinin B levels were measured by ELISA method. The study included 20 girls with idiopathic central precocious puberty 22 girls with premature thelarche and 24 prepubertal controls. While serum kisspeptin, leptin and neurokinin B levels were significantly higher in central precocious puberty and premature thelarche groups compared to controls, no significant difference was found between central precocious puberty and premature thelarche groups. Increased serum levels of leptin, kisspeptin and neurokinin B in patients with premature thelarche and central precocious puberty suggest that they take part during the initiation of pubertal process, however, these markers are not able to differentiate patients with central precocious puberty from premature thelarche.

    Central diabetes insipidus (CDI) is considered idiopathic in 20% to 50% of affected subjects. The purpose of this study was to determine whether a systematic diagnostic workup could achieve better etiologic diagnosis in children and adolescents presenting with polyuria and polydipsia. This is a prospective study conducted at a tertiary referral center. Patients underwent clinical and endocrine evaluations every 6 months and neuroimaging every 6 months for 2 years and yearly for 3 years. Endocrine function and neuroimaging were also reassessed after adult height achievement. A total of 85 consecutive patients with CDI were enrolled at a median age of 7.5 years; those with idiopathic CDI were stratified based on pituitary stalk thickness. To establish the etiology of CDI, we determined the time lag between its onset and the specific diagnosis, the long-term impact on pituitary function, and the overall long-term outcomes. Of the subjects, 24 (28.2%) received an etiologic diagnosis at presentation and 11 (13%) within 2.5 years (n = 7 germinomas and n = 4 Langerhans cell histiocytosis), 7 (8.2%) were lost to follow-up, and 43 (50.6%) were considered to have idiopathic disease and were followed until the median age of 17.3 years. Neuroimaging identified 40 of 43 patients with self-limited inflammatory/autoimmune pituitary stalk thickness within the first 6 months, the severity of which was significantly correlated to pituitary dysfunction. The probability of >10-year-survival without an anterior pituitary defect was related to the severity of pituitary stalk thickness, and 53% showed permanent anterior pituitary defects. Three patients developed Langerhans cell histiocytosis and 1 developed Hodgkin lymphoma after a median of 9 and 13 years, respectively. A diagnostic etiology was achieved in 96% of patients with CDI. Risk stratification based on the degree of pituitary stalk thickness is of prognostic value for long-term outcomes including permanent pituitary

    We investigated the effect of bilateral carotid body resection (bCBR) in a patient with bilateral carotid body tumors on central CO2 sensitivity. We applied multiple square-wave changes in end-tidal CO2 and measured ventilation before the first surgery and at regular intervals for 3 years after surgery. The data were analyzed using a two-compartment model of the ventilatory control system. bCBR resulted in the loss of the fast response to CO2, and a sharp reduction in the magnitude of central CO2 sensitivity (a reduction of about 80% within 3 months after bCBR). Central CO2 sensitivity gradually increased to pre-operative values within 2 years after surgery. These observations are a strong indication for (1) the existence of a tonic influence from the peripheral chemoreceptors of the carotid bodies on central CO2 drive; (2) absence of any recovery of the peripheral drive after bCBR; and (3) neural plasticity causing the regeneration of central drive after bCBR.

    We encountered a rare case of continuously forming bilateral mandibular deciduous central incisor roots after traumatic coronal destruction. The patient, 3 year 3 month old boy, had sustained an external injury which had caused the crowns of hist bilateral deciduous central incisors to fall out when he was 12 months old. Oral examination revealed two small, hard tissues resembling tooth structures on the alveolar ridge in the area of the lost mandibular central incisors. X-ray examination revealed them to be deciduous central incisor roots. We observed the extracted roots histologically and found that the lesion of the crown fracture and pulpal exposure on these roots was completely covered by newly formed irregular dentin and cementoid tissues. In this case, the causes of the continuous root formation were considered to be that the pulp tissues of traumatized teeth were able survive, so the injured lesion was quickly healed and covered with gingival tissue. The vital pulp produced the reparative hard tissue, sealing the site of pulpal exposure and continuing root formation after the trauma.

    The clinical significance of QEEG LORETA data analysis performed sequentially within 6 months is presented in a case report of a predominantly central type severe disabling subjective idiopathic tinnitus (SIT) before and following treatment. The QEEG LORETA data is reported as Z-scores of z = ± 2.54, p < 0.013. The focus is on demonstration of patterns of brain wave oscillations reflecting multiple brain functions in multiple ROIs in the presence of the tinnitus signal (SIT). The patterns of brain activity both high, middle and low frequencies are hypothesized to reflect connectivities within and between multiple neuronal networks in brain. The Loreta source localization non auditory ROI Images at the maximal abnormality in the very narrow band frequency spectra (24.21 Hz), showed the mathematically most probable underlying sources of the scalp recorded data to be greatest in the mid-cingulate, bilateral precuneus, cingulate and the bilateral caudate nucleus. Clinical correlation of the data with the history and course of the SIT is considered an objective demonstration of the affect, behavioral, and emotional component of the SIT. The correlation of the caudate activity, SIT as the traumatic event with the clinical course of PTSD, and the clinical diagnosis of PTSD is discussed. The clinical translation for patient care is highlighted in a SIT patient with multiple comorbidities by translation of QEEG/LORETA electrophysiologic data, as an adjunct to: provide an objectivity of patterns of brain wave activity in multiple regions of interest (ROIs) reflecting multiple brain functions, in response to and in the presence of the tinnitus signal, recorded from the scalp and analyzed with the metrics of absolute power, relative power, asymmetry, and coherence, for the subjective tinnitus complaint (SIT); 2) provide an increase in the accuracy of the tinnitus diagnosis; 3) assess/monitor treatment efficacy; 4) provide a rationale for selection of a combined tinnitus

    Objectives: To evaluate the effect of half adult dose of oral Rifampicin on mean change in best corrected visual acuity and central macular thickness in patients with central serous chorioretinopathy. Methods: Thirty-eight eyes of 31 patients with idiopathic central serous chorioretinopathy (CSCR) were registered. Unaided Visual acuity, best corrected visual acuity was documented and detailed slit lamp examination along with dilated ophthalmoscopy was performed. All subjects were treated with oral Rifampicin 300 mg (half adult dose) daily for 03 months. Patients underwent a complete ocular and systemic examination as well as central macular thickness (CMT) measurement by optical coherence tomography (OCT) every month after starting treatment until four months. Fundus fluorescein angiography (FFA) was performed in recurrent cases. Liver function tests were carried out prior to the treatment and during follow up period. Results: A total of 38 eyes of 31 patients (24 males, 07 females) were included in the study. Mean age of patients was 36.16±3.19 years (range 30-44). Mean best corrected visual acuity (BCVA) before treatment was 0.56±0.11 and improved to 0.47±0.14 at 04 weeks (P<0.001) of treatment. The mean CMT at the time of presentation was 494.39±96.29 um and was decreased to 306.90±50.71 um after 04 weeks of treatment (P<0.001). The mean induced reduction in CMT was 187.48±122 um (P<0.001) while that in BCVA 0.41±0.16 at 04 weeks of treatment (P<0.001). Liver function tests were within normal range before and after the treatment. Conclusion: Half adult dose rifampicin (300mg) is effective and safe in treatment of central serous chorioretinopathy without causing any systemic imbalance. PMID:27882013

    Puberty is a major developmental stage. Damaging mutations, considered as "mistakes of nature", have contributed to the unraveling of the networks implicated in the normal initiation of puberty. Genes involved in the abnormal hypothalamic-pituitary-gonadal (HPG) axis development, in the normosmic idiopathic hypogonadotropic hypogonadism (nIHH), in the X-linked or autosomal forms of Kallmann syndrome and in precocious puberty have been identified (GNRH1, GNRHR, KISS1, GPR54, FGFR1, FGF8, PROK2, PROKR2, TAC3, TACR3, KAL1, PROK2, PROKR2, CHD7, LEP, LEPR, PC1, DAX1, SF-1, HESX-1, LHX3, PROP-1). Most of them were found to play critical roles in HPG axis development and regulation, the embryonic GnRH neuronal migration and secretion, the regulation and action of the hypothalamic GnRH. However, the specific neural and molecular mechanisms triggering GnRH secretion remain one of the scientific enigmas. Although GnRH neurons are probably capable of autonomously generating oscillations, many gonadal steroid-dependent and -independent mechanisms have also been proposed. It is now well proven that the secretion of GnRH is regulated by kisspeptin as well as by permissive or opposing signals mediated by neurokinin B and dynorphin. These three supra-GnRH regulators compose the kisspeptin-neurokinin B-dynorphin neuronal (KNDy) system, a key player in pubertal onset and progression. Moreover, an ongoing increasing number of inhibitory, stimulatory and permissive networks acting upstream on GnRH neurons, such as GABA, NPY, LIN28B, MKRN3 and others integrate diverse hormonal and peripheral signals and have been proposed as the "gate-keepers" of puberty, while epigenetic modifications play also an important role in puberty initiation.

    Background: Genetic factors cause about 15% of male infertility. Azoospermia factors (AZFa, AZFb, and AZFc) present on Yq are most important for spermatogenesis. We have made an attempt to evaluate the frequencies of microdeletions of AZFa, AZFb, AZFc in idiopathic cases of azoospermia and oligozoospermia from central Indian population. Materials and Methods: We have analyzed a total of 156 subjects (95 oligozoospermia and 61 azoospermia) & 50 control subjects. DNA samples were analyzed for microdeletions of Y chromosome by PCR-screening of 18 sequences-tagged-site (STS) markers from different region of the AZF on Yq and SRY on Yp. Results: Out of 156 cases analyzed, 13 (8.33%) subjects (8 azoospermia and 5 oligozoospermia) showed partial deletion of AZF regions, of which deletion in AZFc region was the most common (84.6%) followed by AZFb (15.4%) and AZFa (15.4%). The sites and sizes of deletions varied among patients. Histological study of the testicular tissue of the available subjects, who showed microdeletions of Y chromosome, showed spermatogenic arrest at different stages. The frequency of Y chromosome microdeletion in our subjects was 8.33%. Conclusion: Some Indian studies reported low frequencies of microdeletions than that of our result. We suggest that the frequency of deletions may be affected by the involvement of different genetic factors, ethnic population and different geographical regions. PCR based Y chromosome screening for microdeletions will be useful and great help to infertility clinics for genetic counselling and assisted reproduction. PMID:24783090

    Idiopathic multifocal choroiditis (MFC) and/or punctate inner choroidopathy (PIC) describe a chronic progressive bilateral inflammatory chorioretinopathy that predominantly affect healthy myopic white women with no known associated systemic or ocular diseases. The principal sites of involvement are the retinal pigment epithelium (RPE) and outer retinal spaces; the choroid is not affected during the active phase of the disease. Idiopathic MFC with atrophy is a recently described variant. Although there is no generally accepted standard treatment, anti-inflammatory and anti-VEGF (vascular endothelial growth factor) agents are necessary in the acute stage to control the inflammation and choroidal neovascularization (CNV).

    Bilateral total knee replacement (BTKR) has been associated with a higher incidence of fat embolism (FES) compared to single knee replacement. Consequently, intraoperative monitoring with a pulmonary artery catheter (PAC) has been recommended. This study compares clinical outcome in BTKR patients monitored with central venous pressure versus PAC. A retrospective chart review of 249 consecutive patients undergoing BTKR, 132 of whom had PAC insertion versus 117 who had central line insertion, over a 1-year period were included in the study. Their medical records were reviewed for co-morbidities, baseline characteristics, and type of intraoperative monitoring. Need and duration for postoperative monitoring in the postoperative care, length of hospital stay (LOHS), signs of fat embolism, development of arrhythmias, and respiratory failure were all outcome measures. A total of four patients (1.6%) had FES as per Schonfeld criteria. One of these patients died within 48 h of surgery. They all had PAC monitoring intraoperatively. Pulmonary artery pressure (PAP) remained unchanged during surgery which raises doubt as to the clinical utility and advisability of the use of PAC’s in this setting. There was no statistically significant difference in cardiac or pulmonary complications, or LOHS between the two groups. Central venous pressure monitoring appears to be sufficient in patients undergoing BTKR. PMID:19002531

    Idiopathic central serous chorioretinopathy (CSCR) is a relatively common ophthalmic disorder characterized by the development of a serous detachment of the sensory retina. Psychophysiological factors may trigger or maintain CSCR, though, surprisingly, the association between CSCR and anxiety has yet to be studied. The aims of the present study were threefold: to determine whether 1) Iranian patients with CSCR have higher scores for anxiety, 2) anxiety is lower, if CSCR has been experienced twice, and whether 3) anxiety scores differ between sexes. A total of 30 patients with CSCR and 30 healthy age-and sex-matched controls took part in the study. A brief face-to-face interview was conducted covering demographic variables and history and occurrence of CSCR and assessing anxiety. Compared to healthy controls, anxiety was significantly higher in both first-time and second-time CSCR patients. In CSCR patients, anxiety scores did not differ between sexes. Higher anxiety scores were observed in Iranian patients with CSCR, irrespective of whether this was the first or second occurrence of CSCR. This suggests there is no psychological adaptation in terms of reduced anxiety among patients with repeated CSCR.

    Accurate epidemiological data on common deafness genes are essential to improve the efficiency and to reduce the cost of molecular diagnosis. They may depend on several factors, including a clear delineation of the source of patients being studied. In the present study, we hypothesize that patients with idiopathic sensorineural hearing loss recruited from different sources might reveal discrepancies in the epidemiological results of genetic screening, because patients from different sources might demonstrate distinct clinical or audiologic features and thus result in biased selection of subjects. To elucidate the relative importance of common deafness genes in Taiwanese and to verify our hypothesis, we conducted a prospective project screening mutations in GJB2, SLC26A4 and mitochondrial 12S rRNA gene in a total of 420 Taiwanese families with idiopathic bilateral sensorineural hearing loss, of which 325 families were recruited from hospitals and 95 from hearing rehabilitation facilities. Allele frequencies of common mutations in these three genes and distributions of the corresponding genotypes were then compared between the two groups. The allele frequencies of mutations in SLC26A4, GJB2 and mitochondrial 12S rRNA in the probands of the 420 families were 14.4, 21.7 and 3.8%, respectively. The allele frequency of SLC26A4 mutations in the hospital group was significantly higher than that in the rehabilitation facility group (16.2 vs. 8.4%, chi(2)-test, p < 0.05), whereas no difference in the frequencies of GJB2 mutations and mitochondrial 12S rRNA mutations was found between the two groups. Distributions of probands classified by SLC26A4 genotypes were also different between the two groups (chi(2)-test, p < 0.05). Accordingly, a discrepancy in the genetic screening results might exist between different sources of idiopathic hearing-impaired patients. Further analysis of audiological results and construction of a logistic regression model showed that different

    Pubertal timing is a strongly heritable trait, but no single puberty gene has been identified. Thus, the genetic background of idiopathic central precocious puberty (ICPP) is poorly understood. Overall, the genetic modulation of pubertal onset most likely arises from the additive effect of multiple genes, but also monogenic causes of ICPP probably exist, as cases of familial ICPP have been reported. Mutations in KISS1 and KISSR, coding for kisspeptin and its receptor, involved in GnRH secretion and puberty onset, have been suggested causative for monogenic ICPP. Variation in LIN28B was associated with timing of puberty in genome-wide association (GWA) studies. LIN28B is a human ortholog of the gene that controls, through microRNAs, developmental timing in C. elegans. In addition, Lin28a transgenic mice manifest the puberty phenotypes identified in the human GWAS. Thus, both LIN28B and LIN28A may have a role in pubertal development and are good candidate genes for monogenic ICPP. Thirty girls with ICPP were included in the study. ICPP was defined by pubertal onset before 8 yrs of age, and a pubertal LH response to GnRH testing. The coding regions of LIN28B, LIN28A, KISS1, and KISS1R were sequenced. The missense change in LIN28B was also screened in 132 control subjects. No rare variants were detected in KISS1 or KISS1R in the 30 subjects with ICPP. In LIN28B, one missense change, His199Arg, was found in one subject with ICPP. However, this variant was also detected in one of the 132 controls. No variation in LIN28A was found. We did not find any evidence that mutations in LIN28B or LIN28A would underlie ICPP. In addition, we confirmed that mutations in KISS1 and KISS1R are not a common cause for ICPP.

  14. Bilateral central pain sensitization in rats following a unilateral thalamic lesion may be treated with high doses of ketamine

    PubMed Central

    2013-01-01

    Background Central post-stroke pain is a neuropathic pain condition caused by a vascular lesion, of either ischemic or hemorrhagic origin, in the central nervous system and more precisely involving the spinothalamocortical pathway responsible for the transmission of painful sensations. Few animal models have been developed to study this problem. The objectives of this study were to evaluate different modalities of pain in a central neuropathic pain rat model and to assess the effects of ketamine administered at different doses. Animals were evaluated on the rotarod, Hargreaves, Von Frey and acetone tests. A very small hemorrhage was created by injecting a collagenase solution in the right ventral posterolateral thalamic nucleus. Following the establishment of the neuropathy, ketamine was evaluated as a therapeutic drug for this condition. Results Histopathological observations showed a well localized lesion with neuronal necrosis and astrocytosis following the collagenase injection that was localized within the VPL. No significant change in motor coordination was observed following surgery in either the saline or collagensae groups. In the collagenase group, a significant decrease in mechanical allodynia threshold was observed. A sporadic and transient cold allodynia was also noted. No thermal hyperalgesia was seen following the collagenase injection. Ketamine was then tested as a potential therapeutic drug. A significant decrease in motor coordination was seen only following the administration of 25 mg/kg of ketamine in both groups. An alleviation of mechanical allodynia was achieved only with the high ketamine dose. The minimal effective ketamine serum concentration (150 ng/mL) was only achieved in animals that received 25 mg/kg. Conclusions An intrathalamic hemorrhage induced a bilateral mechanical allodynia in rats. Cold hyperalgesia was observed in 60% of these animals. Mechanical allodynia was alleviated with high doses of ketamine which corresponded

    The idiopathic inflammatory demyelinating disease (IIDD) spectrum has been investigated among different populations, and the results have indicated a low relative frequency of neuromyelitis optica (NMO) among multiple sclerosis (MS) cases in whites (1.2%-1.5%), increasing in Mestizos (8%) and Africans (15.4%-27.5%) living in areas of low MS prevalence. South America (SA) was colonized by Europeans from the Iberian Peninsula, and their miscegenation with natives and Africans slaves resulted in significant racial mixing. The current study analyzed the IIDD spectrum in SA after accounting for the ethnic heterogeneity of its population. A cross-sectional multicenter study was performed. Only individuals followed in 2011 with a confirmed diagnosis of IIDD using new diagnostic criteria were considered eligible. Patients’ demographic, clinical and laboratory data were collected. In all, 1,917 individuals from 22 MS centers were included (73.7% female, 63.0% white, 28.0% African, 7.0% Mestizo, and 0.2% Asian). The main disease categories and their associated frequencies were MS (76.9%), NMO (11.8%), other NMO syndromes (6.5%), CIS (3.5%), ADEM (1.0%), and acute encephalopathy (0.4%). Females predominated in all main categories. The white ethnicity also predominated, except in NMO. Except in ADEM, the disease onset occurred between 20 and 39 years old, early onset in 8.2% of all cases, and late onset occurred in 8.9%. The long-term morbidity after a mean disease time of 9.28±7.7 years was characterized by mild disability in all categories except in NMO, which was scored as moderate. Disease time among those with MS was positively correlated with the expanded disability status scale (EDSS) score (r=0.374; p=<0.001). This correlation was not observed in people with NMO or those with other NMO spectrum disorders (NMOSDs). Among patients with NMO, 83.2% showed a relapsing-remitting course, and 16.8% showed a monophasic course. The NMO-IgG antibody tested using indirect

    Central precocious puberty (CPP) develops due to premature activation of the hypothalamic-pituitary-gonadal (HPG) axis, resulting in early pubertal changes and rapid bone maturation. CPP is associated with lower adult height and increased risk for development of psychological problems. Standard treatment of CPP is based on postponement of pubertal development by blockade of the HPG axis with gonadotropin releasing hormone analogs (GnRHa) leading to abolition of gonadal sex hormones synthesis. Whereas the hormonal and auxological effects of GnRHa are well-researched, there is a lack of knowledge whether GnRHa treatment influences psychological functioning of treated children, despite the fact that prevention of psychological problems is used as one of the main reasons for treatment initiation. In the present study we seek to address this issue by exploring differences in cognitive function, behavior, emotional reactivity, and psychosocial problems between GnRHa treated CPP girls and age-matched controls. Fifteen girls with idiopathic CPP; median age 10.4 years, treated with slow-release GnRHa (triptorelin acetate—Decapeptyl SR® 11.25) and 15 age-matched controls, were assessed with a comprehensive test battery consisting of paper and pencil tests, computerized tasks, behavioral paradigms, heart rate variability, and questionnaires filled in by the children's parents. Both groups showed very similar scores with regard to cognitive performance, behavioral and psychosocial problems. Compared to controls, treated girls displayed significantly higher emotional reactivity (p = 0.016; Cohen's d = 1.04) on one of the two emotional reactivity task conditions. Unexpectedly, the CPP group showed significantly lower resting heart rates than the controls (p = 0.004; Cohen's d = 1.03); lower heart rate was associated with longer treatment duration (r = −0.582, p = 0.037). The results suggest that GnRHa treated CPP girls do not differ in their cognitive or psychosocial

    Background: In central precocious puberty (CPP), the pulse secretion and release of gonadotropin-releasing hormone (GnRH) are increased due to early activation of the hypothalamic-pituitary-gonadal axis, resulting in developmental abnormalities with gonadal development and appearance of secondary sexual characteristics. The CPP without organic disease is known as idiopathic CPP (ICPP). The objective of the study was to evaluate the clinical efficacy and safety of domestic leuprorelin (GnRH analog) in girls with ICPP. Methods: A total of 236 girls with ICPP diagnosed from April 2012 to January 2014 were selected and were randomized into two groups. One hundred fifty-seven girls in the test group were treated with domestic leuprorelin acetate, 79 girls in the control group were treated with imported leuprorelin acetate. They all were treated and observed for 6 months. After 6-month treatment, the percentage of children with peak luteinizing hormone (LH) ≤3.3 U/L, the percentage of children with peak LH/peak follicle stimulating hormone (FSH) ratio <0.6, the improvements of secondary sexual characteristics, gonadal development and sex hormone levels, the change of growth rate of bone age (BA) and growth velocity, and drug adverse effects between two groups were compared. Results: After the treatment, the percentage of children with a suppressed LH response to GnRH, defined as a peak LH ≤3.3 U/L, at 6 months in test and control groups were 96.80% and 96.20%, respectively, and the percentage of children with peak LH/FSH ratio ≤0.6 at 6 months in test and control groups were 93.60% and 93.70%, respectively. The sizes of breast, uterus and ovary of children and the levels of estradiol (E2) were significantly reduced, and the growth rate of BA was also reduced. All the differences between pre- and post-treatment in each group were statistically significant (P < 0. 05), but the differences of the parameters between two groups were not significant (P > 0

    The impact of occult lymph node metastasis on regional recurrence after prophylactic central neck dissection for preoperative, nodal-negative papillary thyroid cancer is controversial. We investigated risk factors for regional lymph node recurrence in papillary thyroid cancer patients who underwent total thyroidectomy and bilateral prophylactic central neck dissection. Analysis was according to clinicopathologic characteristics and occult lymph node metastasis patterns. This multicenter study enrolled 211 consecutive patients who underwent total thyroidectomy with bilateral prophylactic central neck dissection for papillary thyroid cancer without evidence of central lymph node metastasis on preoperative imaging. Clinicopathologic features and central lymph node metastasis patterns were analyzed for predicting regional recurrence. Multivariate Cox regression analysis was used to identify independent factors for recurrence. Median follow-up time was 43 months (24-95 months). Ten patients (4.7%) showed regional lymph node recurrence. The estimated 5-year, regional recurrence-free survival was 95.2%. Tumor size ≥1 cm, central lymph node metastasis, lymph node ratio, and prelaryngeal lymph node metastasis were associated with regional recurrence in univariate analysis (P < .05). In multivariate analysis, a lymph node ratio ≥ 0.26 was a significant risk factor for regional lymph node recurrence (odds ratio = 11.63, P = .003). Lymph node ratio ≥ 0.26 was an independent predictor of worse recurrence-free survival on Cox regression analysis (hazard ratio = 11.49, P = .002). Although no significant association was observed between the presence of occult lymph node metastasis and regional recurrence, lymph node ratio ≥ 0.26 was an independent predictor of regional lymph node recurrence in papillary thyroid cancer patients who underwent total thyroidectomy and bilateral prophylactic central neck dissection.

    Idiopathic anaphylaxis is a diagnosis of exclusion after other causes have been thoroughly evaluated and excluded. The pathogenesis of idiopathic anaphylaxis remains uncertain, although increased numbers of activated lymphocytes and circulating histamine-releasing factors have been implicated. Signs and symptoms of patients diagnosed with idiopathic anaphylaxis are indistinguishable from the manifestations of other forms of anaphylaxis. Treatment regimens are implemented based on the frequency and severity of patient symptoms and generally include the use of epinephrine autoinjectors, antihistamines, and steroids. The prognosis of idiopathic anaphylaxis is generally favorable with well-established treatment regimens and effective patient education. Copyright © 2015 Elsevier Inc. All rights reserved.

    Background: Dysconnectivity hypothesis of schizophrenia has been increasingly emphasized. Recent researches showed that this dysconnectivity might be related to occurrence of auditory hallucination (AH). However, there is still no consistent conclusion. This study aimed to explore intrinsic dysconnectivity pattern of whole-brain functional networks at voxel level in schizophrenic with AH. Methods: Auditory hallucinated patients group (n = 42 APG), no hallucinated patients group (n = 42 NPG) and normal controls (n = 84 NCs) were analyzed by resting-state functional magnetic resonance imaging. The functional connectivity metrics index (degree centrality [DC]) across the entire brain networks was calculated and evaluated among three groups. Results: DC decreased in the bilateral putamen and increased in the left superior frontal gyrus in all the patients. However, in APG, the changes of DC were more obvious compared with NPG. Symptomology scores were negatively correlated with the DC of bilateral putamen in all patients. AH score of APG positively correlated with the DC in left superior frontal gyrus but negatively correlated with the DC in bilateral putamen. Conclusion: Our findings corroborated that schizophrenia was characterized by functional dysconnectivity, and the abnormal DC in bilateral putamen and left superior frontal gyrus might be crucial in the occurrence of AH.

    Idiopathic anaphylaxis is a prednisone-responsive condition without external cause, but it can coexist with food-, medication-, or exercise-induced anaphylaxis. Mast cell activation may occur at night or after foods that have been eaten with impunity many times previously. Idiopathic anaphylaxis can be classified into frequent (if there are six or more episodes per year or two episodes in the last 2 months) or infrequent (if episodes occur less often). Idiopathic anaphylaxis-generalized consists of urticaria or angioedema associated with severe respiratory distress, syncope or hypotension, and gastrointestinal symptoms. Idiopathic anaphylaxis-angioedema consists of massive tongue enlargement or severe pharyngeal or laryngeal swelling with urticaria or peripheral angioedema. The differential diagnosis of idiopathic anaphylaxis is reviewed, and treatment approaches are presented.

    Identification of idiopathic hypersomnia dates back 20 years only. It typically consists of prolonged nocturnal sleep, great difficulty waking up in the morning or at the end of a nap, and constant or recurrent excessive daytime sleepiness. Complete and incomplete forms are encountered. Twenty-three subjects fulfilling ICSD criteria are reported with clinical, polysomnographic and immunogenetic data. Considering differential diagnosis is an important step in the diagnosis of idiopathic hypersomnia. Idiopathic hypersomnia is much less frequent than narcolepsy. A strong genetic component is suggested by the high proportion of familial cases. No association with HLA has been evidenced to date.

    Patients with bilateral central vein stenosis present a unique challenge: treatment options are limited, largely unproven and associated with reputedly poor outcomes. Our aim was to compare patency rates of different access and renal replacement treatment (RRT) modalities in patients with bilateral central vein stenosis/occlusion. Data on all patients presenting to a tertiary referral vascular access centre with end-stage vascular access (defined by bilateral central vein stenosis/occlusion with loss of upper limb access) over a 5-year period were included. 3, 6 and 12-month patencies of translumbar catheters (TLs), tunnelled femoral catheters (Fem), native long saphenous vein loops (SV), prosthetic mid-thigh loop grafts (ThGr), peritoneal dialysis (PD), and expedited donation after cardiac death (DCD) cadaveric renal transplants (Tx) via local allocation policies were compared using log-rank test. Kaplan-Meier survival analysis was used to estimate long-term access survival. One hundred forty-six vascular access modalities were attempted in 62 patients (62 Fem, 25 TL, 15 SV, 25 ThGr, 8 PD, 11 Tx). Median follow-up was 876±57 days. Three, 6 and 12-month primary-assisted patencies for each modality were as follows: Fem: 75.4%, 60% and 28%; TL: 88%, 65% and 50%; SV: 87.5%, 60% and 44.6%; ThGr: 64%, 38% and 23.5%; PD: 62.5%, 62.5% and 50%; Tx: 72.7%, 72.7% and 72.7%. SV had better secondary patency at 900 days (76.9%) than ThGr (49.2%) or Fem (35.8%) (p<0.01). No patients died as a result of loss of access. Patients with bilateral central vein stenosis often require more than one vascular access modality to achieve a "personal access solution." Native long saphenous vein loops provided the best long-term patency. Expedited renal transplantation with priority local allocation of DCD organs to patients with precarious vascular access provides a potential solution to this difficult problem.

    Scoliosis refers to curves exceeding 10 degrees observed through posterioanterior direct radiography. In fact, the diagnosis for idiopathic scoliosis is accepted to exclude already available causes. The aim of this paper was to review the etiopathogenesis, classification systems and the treatment management of idiopathic scoliosis. A search in the National Library of Medicine (Pubmed) database using the key words 'idiopathic' and 'scoliosis' was performed. For the literature review, papers concerning the etiopathogenesis, classification and treatment were selected among these articles. A search in the National Library of Medicine (Pubmed) database using the key words 'idiopathic' and 'scoliosis' yielded 4518 articles published between 1947 and 2013. The main hypothesis put forward included genetic factors, hormonal factors, bone and connective tissue anomalies. King, Lenke, Coonrad and Peking Union Medical College (PUMC) classifications were the main classification systems for idiopathic scoliosis. Exercise, bracing and anterior, posterior or combined surgery when indicated are the choices for the treatment. Every idiopathic scoliosis case has to be managed to its own characteristics. It is the post-operative appearance that the surgeons are perhaps the least interested but the adolescent patients the most interested in. The aim of scoliosis surgery is to restore the spine without neurological deficit.

    A 55-year-old male presented with serous retinal detachment over 3 months in his right eye. His left eye was blind due to retinal pigment epithelium detachment since 1997 with atrophy of the neurosensory retina. Fluorescein angiography had previously shown bilateral polypoidal choroidal vasculopathy (PCV). Optical coherence tomography (OCT) confirmed PCV with central involvement. The patient underwent intravitreal injections of 6x Lucentis, 4x Avastin and one injection of aflibercept. PCV recurred from 1 to 4 months after each treatment. The patient had history of stroke, hypertension, and atrial fibrillation and was started on oral eplerenone 25 mg/day in October 2014, which resulted in a long-term ongoing complete retinal reattachment. OCT ganglion cell and inner plexiform layers showed full recovery of the fovea in the right eye and irreversible in the left eye. Low-dose eplerenone may resolve recalcitrant PCV with central involvement. The duration of treatment remains uncertain.

  10. Idiopathic hypersomnia.

    PubMed

    Billiard, M

    1996-08-01

    Idiopathic hypersomnia is not as well delineated as narcolepsy and its history is much more recent. There are at least two forms of the disorder: (1) a polysymptomatic form, characterized by excessive daytime sleepiness, nocturnal sleep of abnormally long duration, and signs of sleep drunkenness on awakening, and (2) a monosymptomatic form that manifests only by excessive daytime sleepiness. The most widely used laboratory procedures are nocturnal polysomnographic recording following by an MSLT demonstrating a mean sleep latency of less than 10 minutes. At least in the polysymptomatic form, however, continuous polysomnography on an ad lib protocol deserves to be performed to catch the abnormally long major sleep episode and the long unrefreshing naps. Idiopathic hypersomnia is probably one of the most overdiagnosed sleep disorders. Several other disorders must be excluded before the diagnosis can be considered conclusive. Treatment of idiopathic hypersomnia relies on stimulants, which are frequently less effective and less well tolerated than in narcolepsy.

    Selective silencing of the cyclooxygenase-2 (COX-2) gene with the loss of the antifibrotic mediator prostaglandin E2 contributes to the fibrotic process in idiopathic pulmonary fibrosis (IPF). This study explored the role of G9a- and enhancer of zeste homolog 2 (EZH2)-mediated methylation of histone H3 lysine 9 (H3K9me3) and histone H3 lysine 27 (H3K27me3) in COX-2 silencing in IPF. Chromatin immunoprecipitation (ChIP) and re-ChIP assays demonstrated marked increases in H3K9me3, H3K27me3, and DNA methylation, together with their respective modifying enzymes G9a, EZH2, and DNA methyltransferases (Dnmts) and respective binding proteins heterochromatin protein 1 (HP1), polycomb protein complex 1 (PRC1) and methyl CpG binding protein 2 (MeCP2), at the COX-2 promoter in lung fibroblasts from patients with IPF (F-IPFs) compared with fibroblasts from nonfibrotic lungs. HP1, EZH2, and MeCP2 in turn were associated with additional repressive chromatin modifiers in F-IPFs. G9a and EZH2 inhibitors and small interfering RNAs and the Dnmt1 inhibitor markedly reduced H3K9me3 (49-79%), H3K27me3 (44-81%), and DNA methylation (61-97%) at the COX-2 promoter. These reductions were correlated with increased histone H3 and H4 acetylation, resulting in COX-2 mRNA and protein reexpression in F-IPFs. Our results support a central role for G9a- and EZH2-mediated histone hypermethylation and a model of bidirectional, mutually reinforcing, and interdependent crosstalk between histone hypermethylation and DNA methylation in COX-2 epigenetic silencing in IPF.-Coward, W.

    Gonadotropin-releasing hormone analogues (GnRHa) represent the gold standard treatment for central precocious puberty (CPP). We aimed to assess the effects of GnRHa treatment on metabolic outcomes, bone status, and polycystic ovary syndrome (PCOS) prevalence in young girls with idiopathic CPP (ICPP). We enrolled 94 ICPP girls who were at least 2 years after menarche and had already attained adult height at the time of the study: 56 previously treated with depot triptorelin (3.4 ± 0.6 years) and 38 untreated. Auxological parameters, lipid profile, homeostatic model assessment of insulin resistance (HOMA-IR), bone state, and prevalence of PCOS were assessed. The 2 groups were similar for body mass index (BMI) and waist circumference. HOMA-IR, dehydroepi-androsterone sulfate, and Δ4-androstenedione were higher in the treated than in the untreated subjects (p < 0.001). Significant differences were found for amplitude-dependent speed of sound (p < 0.03) and bone transmission time z-scores (p < 0.01). The prevalence of PCOS was higher in the treated than in the untreated subjects (p < 0.04). GnRHa therapy is associated with hyperandrogenism and an increase in insulin resistance and PCOS prevalence, but not with increased BMI or lipid profile alterations. Long-term evaluations at the time of expected peak bone mass achievement are needed to understand the persistent or transient nature of subtle bone abnormalities. © 2017 S. Karger AG, Basel.

    A novel, modified presurgical nasoalveolar molding (MPNAM) device with retraction screw was designed and used in patients with bilateral complete cleft lip and palate (BCCLP) to rapidly retract and centralize the protuberant and malpositioned premaxilla and correct the nasolabial and palatal deformities. The orthopedic effects and possible complications were evaluated. Nine patients with BCCLP who met the inclusion criteria were selected. After the maxillary model was obtained, the new MPNAM device with retraction screw was designed and worn until cheilorrhaphy. Changes in local deformities and complications were observed continuously, and the orthopedic effect was evaluated. All patients quickly adapted to the MPNAM appliance, and the treatment was finished after 5-8 return visits. The columella was significantly prolonged, the nasal tip was elevated, and the collapsed nasal dome was obviously improved. Simultaneously, the premaxilla was rapidly retracted and rotated, and gradually centralized; the clefts were gradually reduced and closed, and a nearly normal dental arch was formed. Although there were some complications, the orthopedic treatment was continued until cheiloplasty. The MPNAM device with retraction screw can simultaneously correct nasolabial and palatal deformities and also rapidly retract and centralize the premaxilla.

  14. Idiopathic hypersomnia.

    PubMed

    Billiard, Michel; Sonka, Karel

    2016-10-01

    Idiopathic hypersomnia continues to evolve from the concept of "sleep drunkenness" introduced by Bedrich Roth in Prague in 1956 and the description of idiopathic hypersomnia with two forms, polysymptomatic and monosymptomatic, by the same Bedrich Roth in 1976. The diagnostic criteria of idiopathic hypersomnia have varied with the successive revisions of the International classifications of sleep disorders, including the recent 3rd edition. No epidemiological studies have been conducted so far. Disease onset occurs most often during adolescence or young adulthood. A familial background is often present but rigorous studies are still lacking. The key manifestation is hypersomnolence. It is often accompanied by sleep of long duration and debilitating sleep inertia. Polysomnography (PSG) followed by a multiple sleep latency test (MSLT) is mandatory, as well as a 24 h PSG or a 2-wk actigraphy in association with a sleep log to ensure a total 24-h sleep time longer than or equal to 66O minutes, when the mean sleep latency on the MSLT is longer than 8 min. Yet, MSLT is neither sensitive nor specific and the polysomnographic diagnostic criteria require continuous readjustment and biologic markers are still lacking. Idiopathic hypersomnia is most often a chronic condition though spontaneous remission may occur. The condition is disabling, sometimes even more so than narcolepsy type 1 or 2. Based on neurochemical, genetic and immunological analyses as well as on exploration of the homeostatic and circadian processes of sleep, various pathophysiological hypotheses have been proposed. Differential diagnosis involves a number of diseases and it is not yet clear whether idiopathic hypersomnia and narcolepsy type 2 are not the same condition. Until now, the treatment of idiopathic hypersomnia has mirrored that of the sleepiness of narcolepsy type 1 or 2. The first randomized, double-blind, placebo-controlled trials of modafinil have just been published, as well as a double

    2006-01-01

    Lipoid pneumonia is a rare pulmonary disorder having no classical radiological appearance. We report a 33-year-old male, ex-smoker who was referred to us with history of cough, mild mucoid expectoration and progressively increasing dyspnoea since one year. He was investigated at local hospital and was treated with 30 mg prednisolone per day for 6 months for sarcoidosis without any response. On examination, he was normal except for fine basal crepitations in chest. Pulmonary function test (PFT) revealed mild airway obstruction. High resolution computerised tomographic scan (HRCT scan) revealed bilateral reticulonodular shadows and bronchiectasis in lower zones. Open lung biopsy revealed lipoid pneumonia. As there was no history of nasal distillation of oils, it was diagnosed to be idiopathic. The relevant literature is reviewed.

  18. Bilateral cellulitis.

    2015-09-21

    We present a case of bilateral lesions in a 50-year-old man, which were on first impression mistaken for and initially treated as bilateral cellulitis. We propose that bilateral cellulitis, as opposed to unilateral, is rare and that other aetiologies should be considered in evaluating a patient with bilateral lesions. The differential diagnosis includes stasis-dermatitis, lipodermatosclerosis, lymphoedema and vascular lesions such as Kaposi sarcoma, as was identified in this case. Early consultation with dermatology and biopsy in unclear cases mitigates the unnecessary use of prolonged antibiotics, antibiotic resistance and Clostridium difficile infections. HIV testing is an essential screening test in all adults who present with non-specific viral symptoms and rash.

  19. Echinoderms Have Bilateral Tendencies

    Echinoderms take many forms of symmetry. Pentameral symmetry is the major form and the other forms are derived from it. However, the ancestors of echinoderms, which originated from Cambrian period, were believed to be bilaterians. Echinoderm larvae are bilateral during their early development. During embryonic development of starfish and sea urchins, the position and the developmental sequence of each arm are fixed, implying an auxological anterior/posterior axis. Starfish also possess the Hox gene cluster, which controls symmetrical development. Overall, echinoderms are thought to have a bilateral developmental mechanism and process. In this article, we focused on adult starfish behaviors to corroborate its bilateral tendency. We weighed their central disk and each arm to measure the position of the center of gravity. We then studied their turning-over behavior, crawling behavior and fleeing behavior statistically to obtain the center of frequency of each behavior. By joining the center of gravity and each center of frequency, we obtained three behavioral symmetric planes. These behavioral bilateral tendencies might be related to the A/P axis during the embryonic development of the starfish. It is very likely that the adult starfish is, to some extent, bilaterian because it displays some bilateral propensity and has a definite behavioral symmetric plane. The remainder of bilateral symmetry may have benefited echinoderms during their evolution from the Cambrian period to the present. PMID:22247765

    This meta-analysis is to evaluate the effects and safety of the combination therapy for girls with idiopathic central precocious puberty (ICPP). Electronic databases were searched for randomized controlled trials (RCTs) and clinical controlled trials (CCTs) that adopted gonadotropin-releasing hormone analogue (GnRHa) therapy and GnRHa plus growth hormone (GH) combination therapy to treat ICPP girls. A total of six RCTs (162 patients) and six CCTs (247 patients) were included. Compared to the GnRHa therapy group, the combination therapy group achieved taller final height (mean difference, MD = 2.81 cm, 95 % CI 1.76-3.87, four CCTs; MD = 4.30 cm, 95 % CI 0.59-8.01, one RCT); greater progression of final height compared with target height (MD = 3.92 cm, 95 % CI 3.12-4.73, four CCTs; MD = 4.00 cm, 95 % CI 1.93-6.07, One RCT) and larger height gains (MD = 3.49 cm, 95 % CI 0.97-6.01, four CCTs; MD = 3.88 cm, 95 % CI 0.15-7.61, one RCT). No severe adverse effects of treatment were reported. For ICPP girls, the GnRHa and GH combination therapy had advantages over GnRHa alone on final height and no severe adverse effects were reported. We recommend comprehensive assessment of the individual growth rate, patient compliance, the clinical effects, the height expectations of individual patients and the treatment cost to the family in order to identify the best therapy for individual patients.

    The aim of the study was to determine whether polymorphisms in toll-like receptor 4 (TLR4) confer susceptibility to rheumatoid arthritis (RA) and juvenile idiopathic arthritis (JIA) in a central south Chinese Han population. Genotyping for six well studied polymorphisms (rs4986790, rs4986791, rs10759932, rs41426344, rs11536889 and rs7873784) in TLR4 gene were conducted in 1074 unrelated patients with RA and 1692 healthy control subjects, as well as in 217 unrelated patients with JIA and 378 healthy control subjects using direct sequencing technique. Comparisons between cases and controls in alleles, genotypes and haplotypes were carried out using Fisher's exact test. Significant genetic associations were detected between the 3'UTR rs41426344C and RA (p < 0.001, p adj < 0.001, OR = 2.24) and JIA (p < 0.001, p adj < 0.001, OR = 2.05). In addition, rs4986790G was found to be significantly associated with the susceptibility for RA (p = 0.005, p adj = 0.03, OR = 3.43), but not for JIA (p = 0.06, p adj = 0.36, OR = 2.65). Furthermore, significant increasing in the distributions of haplotypes H4 and H10 in RA (H4: p = 0.001, OR = 1.13; H10: p = 0.001, OR = 1.15) and JIA (H4: p = 0.04, OR = 2.06; H10: p = 0.02, OR = 2.47) were also found. Moreover, the frequency of rs41426344C significantly increased in RF-positive and anti-CCP positive subjects both in RA (RF(+): p <0.0001, OR = 2.33; anti-CCP(+): p =0.008, OR = 2.79) and JIA (RF(+): p =0.02, OR = 2.91; anti-CCP(+): p = 0.02, OR = 2.78). Our study suggested that rs41426344 and rs4986790 of TLR4 might contribute to RA, and rs41426344 might contribute to JIA pathogenesis in central south Chinese Han population.

    Acquired limbal stem cell deficiency (LSCD) describes a condition in which the corneal limbal stem cells are altered or destroyed, typically due to ocular trauma, chronic allergy or inflammation. Idiopathic LSCD is a term used to describe limbal stem cell failure in the absence of any identifiable causative factor. While several cases of adult-onset LSCD have been identified previously, this case report describes a rare presentation of bilateral asymmetric idiopathic paediatric limbal stem cell deficiency in a sixteen-year-old male with an otherwise unremarkable ocular history.

    A case of central carcinoma of the mandible arising from a recurrent odontogenic keratocyst is reported. A 38-year-old man was admitted to the Tokai University Hospital due to postoperative infection of a recurrent odontogenic keratocyst of the left mandible. He had had a cystectomy for an odontogenic keratocyst 4 years ago. The lesion revealed bony destruction of the mandible with worm-eating shaped margins with extension to the facial skin. A biopsy specimen revealed squamous cell carcinoma. The mandible was resected with facial skin and the sublingual space was dissected to preserve the lingual nerve. The oral and the facial resections were reconstructed with a titanium plate and bilateral rectus abdominis myocutaneous free flaps. The plate was removed due to infection around the margins and readjustment of the flaps was conducted 5 months after the surgery. He has not had a local relapse, metastasis, or incisional hernia for 8 months following surgery. Good occlusion has been attained by the residual mandible, and he is able to eat without any problems.

  5. Bilateral vestibulopathy.

    2016-01-01

    The leading symptoms of bilateral vestibulopathy (BVP) are postural imbalance and unsteadiness of gait that worsens in darkness and on uneven ground. There are typically no symptoms while sitting or lying under static conditions. A minority of patients also have movement-induced oscillopsia, in particular while walking. The diagnosis of BVP is based on a bilaterally reduced or absent function of the vestibulo-ocular reflex (VOR). This deficit is diagnosed for the high-frequency range of the angular VOR by a bilaterally pathologic bedside head impulse test (HIT) and for the low-frequency range by a bilaterally reduced or absent caloric response. If the results of the bedside HIT are unclear, angular VOR function should be quantified by a video-oculography system (vHIT). An additional test supporting the diagnosis is dynamic visual acuity. Cervical and ocular vestibular-evoked myogenic potentials (c/oVEMP) may also be reduced or absent, indicating impaired otolith function. There are different subtypes of BVP depending on the affected anatomic structure and frequency range of the VOR deficit: impaired canal function in the low- and/or high-frequency VOR range only and/or otolith function only; the latter is very rare. The etiology of BVP remains unclear in more than 50% of patients: in these cases neurodegeneration is assumed. Frequent known causes are ototoxicity mainly due to gentamicin, bilateral Menière's disease, autoimmune diseases, meningitis and bilateral vestibular schwannoma, as well as an association with cerebellar degeneration (cerebellar ataxia, neuropathy, vestibular areflexia syndrome=CANVAS). In general, in the long term there is no improvement of vestibular function. There are four treatment options: first, detailed patient counseling to explain the cause, etiology, and consequences, as well as the course of the disease; second, daily vestibular exercises and balance training; third, if possible, treatment of the underlying cause, as in bilateral

    Macular telangiectasia type 2-also known as idiopathic perifoveal telangiectasia and juxtafoveolar retinal telangiectasis type 2A or Mac Tel 2-is an acquired bilateral neurodegenerative macular disease that usually manifests itself during the fourth to sixth decades of life and is characterized by minimal dilatation of the parafoveal capillaries with graying of the retinal area involved, a lack of lipid exudation, right-angled retinal venules, refractile deposits in the superficial retina, hyperplasia of the retinal pigment epithelium, foveal atrophy, and subretinal neovascularization (SRNV). Optical coherence tomography images typically demonstrate intraretinal hyporeflective spaces that are usually not related to retinal thickening or fluorescein leakage. The typical fluorescein angiographic finding is a deep intraretinal hyperfluorescent leakage in the temporal parafoveal area. With time the leakage may involve the whole parafovea, but does not extend to the center of the fovea. Long-term prognosis for central vision is variable and depends on the development of SRNV or macular atrophy. Pathogenesis remains unclear, but Müller cells and macular pigment appear to play a central role. Currently there is no known treatment for the underlying cause of this condition, but treatment of the SRNV may be beneficial. Copyright © 2013 Elsevier Inc. All rights reserved.

    The rostral ventral tegmental area (VTAR) and central nucleus of amygdala (CeA) are considered the main regions for induction of psychological dependence on abused drugs, such as morphine. The main aim of this study was to investigate the transient inhibition of each right and left side as well as both sides of the VTAR and the CeA by lidocaine (2%) on morphine reward properties using the conditioned place preference (CPP) method. Male Wistar rats (250±20 g) 7 days after recovery from surgery and cannulation were conditioned to morphine (7.5 mg/kg) in CPP apparatus. Five minutes before morphine injection in conditioning phase, lidocaine was administered either uni- or bilaterally into the VTAR (0.25 μL/site) or CeA (0.5 μL/site). The results revealed that lidocaine administration into the left side, but not the right side of the VTAR and the CeA reduced morphine CPP significantly. The reduction was potentiated when lidocaine was injected into both sides of the VTAR and the CeA. The number of compartment crossings was reduced when lidocaine was injected into both sides of the VTAR and the CeA as well as the left side. Rearing was reduced when lidocaine was injected into the right, but not the left side of the VTAR. Sniffing and rearing increased when animals received lidocaine in the right side and reduced in the group that received lidocaine in the left side of the CeA. It was concluded that the right and the left side of VTAR and the CeA play different roles in morphine-induced activity and reward. © 2016 John Wiley & Sons Australia, Ltd.

    Approximately 20% of patients suffering from stroke with pure or predominant sensory symptoms (referred to as sensory stroke patients) develop central poststroke pain (CPSP). It is largely unknown what distinguishes these patients from those who remain pain free. Using quantitative sensory testing (QST), we analyzed the somatosensory profiles of 50 patients with chronic sensory stroke, of which 25 suffered from CPSP. As compared with reference data from healthy controls, patients with CPSP showed alterations of thermal and mechanical thresholds on the body area contralateral to their stroke (P < 0.01). Patients with sensory stroke but without CPSP (non-pain sensory stroke [NPSS] patients) exhibited similar albeit less pronounced contralesional changes. Paradoxical heat sensation (PHS) and dynamic mechanical allodynia (DMA) showed higher values in CPSP, and an elevated cold detection threshold (CDT) was seen more often in CPSP than in patients with NPSS (P < 0.05). In patients with CPSP, changes in CDT, PHS, dynamic mechanical allodynia, and temporal pain summation (wind-up ratio) each correlated with the presence of pain (P < 0.05). On the homologous ipsilesional body area, both patient groups showed additional significant abnormalities as compared with the reference data, which strongly resembled the contralesional changes. In summary, our analysis reveals that CPSP is associated with impaired temperature perception and positive sensory signs, but differences between patients with CPSP and NPSS are subtle. Both patients with CPSP and NPSS show considerable QST changes on the ipsilesional body side. These results are in part paralleled by recent findings of bilaterally spread cortical atrophy in CPSP and might reflect chronic maladaptive cortical plasticity, particularly in patients with CPSP.

    Background: A large proportion of the patients with papillary thyroid microcarcinoma are young women. Therefore, minimally invasive endoscopic thyroidectomy with central neck dissection (CND) emerged and showed well-accepted results with improved cosmetic outcome, accelerated healing, and comforting the patients. This study aimed to evaluate the safety and effectiveness of robotic total thyroidectomy with CND via bilateral axillo-breast approach (BABA), compared with conventional open procedure in papillary thyroid microcarcinoma. Methods: One-hundred patients with papillary thyroid microcarcinoma from March 2014 to January 2015 in Jinan Military General Hospital of People's Liberation Army (PLA) were randomly assigned to robotic group or conventional open approach group (n = 50 in each group). The total operative time, estimated intraoperative blood loss, numbers of lymph node removed, visual analog scale (VAS), postoperative hospital stay time, complications, and numerical scoring system (NSS, used to assess cosmetic effect) were analyzed. Results: The robotic total thyroidectomy with CND via BABA was successfully performed in robotic group. There were no conversion from the robotic surgeries to open or endoscopic surgery. The subclinical central lymph node metastasis rate was 35%. The mean operative time of the robotic group was longer than that of the conventional open approach group (118.8 ± 16.5 min vs. 90.7 ± 10.3 min, P < 0.05). The study showed significant differences between the two groups in terms of the VASs (2.1 ± 1.0 vs. 3.8 ± 1.2, P < 0.05) and NSS (8.9 ± 0.8 vs. 4.8 ± 1.7, P < 0.05). The differences between the two groups in the estimated intraoperative blood loss, postoperative hospital stay time, numbers of lymph node removed, postoperative thyroglobulin levels, and complications were not statistically significant (all P > 0.05). Neither iatrogenic implantation nor metastasis occurred in punctured porous channel or chest wall in both groups

    1968-01-01

    Cardiomyopathies are certain heart diseases of unknown etiology and pathogenesis, occurring mostly in tropical and subtropical areas, where they constitute a major clinical problem and sometimes a public health problem. The need for international co-operation in the study of such forms of heart disease has long been recognized and WHO convened informal meetings of investigators on various aspects of the subject in 1964, 1965 and 1966. Out of these have arisen co-operative studies co-ordinated by WHO. In November 1967 a fourth informal meeting was held in Kingston, Jamaica, to review the following topics: the progress reports from all co-operating laboratories; the different types of cardiomyopathies; past experience with cardiac registries, and the diagnostic importance of coronary angiography. Steps were taken towards the formulation of a standard terminology, since too many confusing names are currently employed to mean “cardiomegaly of unknown origin”. A common name, “idiopathic cardiomegaly”, was therefore suggested for future use. The account presented here was prepared by Dr Z. Fejfar, Chief Medical Officer, Cardiovascular Diseases, World Health Organization, Geneva, on behalf of the other participants and is a précis of some of the information that was exchanged, some of the views that were expressed and of the suggestions that were made.

    Chronic urticaria is the most common skin diseases, characterized by chronic cutaneous lesions which severely debilitates patients in several aspects of their everyday life. Vitamin D is known to exert several actions in the immune system and to influence function and differentiation of mast cells, central role players in the pathogenesis of chronic idiopathic urticaria. This study was performed to evaluate the relationship between vitamin D levels and susceptibility to chronic idiopathic urticaria. One hundred and fourteen patients with chronic idiopathic urticaria were recruited in this study along with one hundred and eighty seven sex-matched and age-matched healthy volunteers as the control group. For each patient, urticaria activity score was calculated and autologous serum skin test was done. Vitamin D metabolic statue was measured in serum as 25 hydroxyvitamin D using enzyme immunoassay method. Patients with chronic idiopathic urticaria significantly showed lower levels of vitamin D. Vitamin D deficiency was significantly associated with increased susceptibility to chronic idiopathic urticaria. There was a significant positive correlation between vitamin D levels and urticaria activity score. This study showed that patients with chronic idiopathic urticaria had reduced levels of vitamin D, while vitamin D deficiency could increase susceptibility to chronic idiopathic urticaria.

  14. Idiopathic oedema and diuretics.

    PubMed Central

    Diuretic abuse has been invoked as the cause of idiopathic oedema. In this study, eight patients with idiopathic oedema were studied. Symptoms and weight variation continued despite the proven absence of diuretics in seven of them as determined by urinary chromatograms. Idiopathic oedema cannot therefore be attributed to diuretic use alone. PMID:3671223

  15. Bilateral sudden sensorineural hearing loss: review.

    PubMed

    Sara, S A; Teh, B M; Friedland, P

    2014-01-01

    Unilateral and bilateral sudden sensorineural hearing loss represent different disease entities. The unilateral condition is more common and predominantly idiopathic, and up to 65 per cent of patients spontaneously recover hearing. Conversely, the bilateral condition is rare, mostly associated with serious systemic conditions, and has a higher prevalence of morbidity and mortality. A literature search using the PubMed database was conducted using the MeSH terms 'sudden', 'bilateral' and 'sensorineural hearing loss'. One hundred and three reported cases of bilateral sudden sensorineural hearing loss were identified. The condition is most often associated with toxic, autoimmune, neoplastic and vascular conditions. A younger age of onset, with a bimodal age distribution, was seen for bilateral sudden sensorineural hearing loss, compared with the unilateral condition. Patients with the bilateral condition had more profound hearing loss, with poorer recovery and a 35 per cent mortality rate. Vestibular symptoms were also less common than in the unilateral condition. The presentation of bilateral sudden onset sensorineural hearing loss is a medical emergency requiring thorough and urgent investigation to exclude life-threatening and reversible conditions.

    Idiopathic pulmonary fibrosis (IPF) occurs predominantly in middle-aged and older adults and accounts for 20% to 30% of interstitial lung diseases. It is usually progressive, resulting in respiratory failure and death. Diagnostic criteria for IPF have evolved over the years, and IPF is currently defined as a disease characterized by the histopathologic pattern of usual interstitial pneumonia occurring in the absence of an identifiable cause of lung injury. Understanding of the pathogenesis of IPF has shifted away from chronic inflammation and toward dysregulated fibroproliferative repair in response to alveolar epithelial injury. Idiopathic pulmonary fibrosis is likely a heterogeneous disorder caused by various interactions between genetic components and environmental exposures. High-resolution computed tomography can be diagnostic in the presence of typical findings such as bilateral reticular opacities associated with traction bronchiectasis/bronchiolectasis in a predominantly basal and subpleural distribution, along with subpleural honeycombing. In other circumstances, a surgical lung biopsy may be needed. The clinical course of IPF can be unpredictable and may be punctuated by acute deteriorations (acute exacerbation). Although progress continues in unraveling the mechanisms of IPF, effective therapy has remained elusive. Thus, clinicians and patients need to reach informed decisions regarding management options including lung transplant. The findings in this review were based on a literature search of PubMed using the search terms idiopathic pulmonary fibrosis and usual interstitial pneumonia, limited to human studies in the English language published from January 1, 2000, through December 31, 2013, and supplemented by key references published before the year 2000.

  19. Gait in 5-year-old children with idiopathic clubfoot

    PubMed Central

    Lööf, Elin; Andriesse, Hanneke; André, Marie; Böhm, Stephanie; Broström, Eva W

    2016-01-01

    Background and purpose Idiopathic clubfoot can be bilateral or unilateral; however, most studies of gait have assessed clubfoot cases as one uniform group. The contralateral foot in children with unilateral clubfoot has shown deviations in pedobarographic measurements, but it is seldom included in studies of gait. We evaluated gait in children with idiopathic clubfoot, concentrating on foot involvement. Patients and methods Three-dimensional gait analyses of 59 children, mean age 5.4 years, with bilateral (n = 30) or unilateral (n = 29) idiopathic clubfoot were stratified into groups of bilateral, unilateral, or contralateral feet. Age-matched controls (n = 28) were evaluated for comparison. Gait assessment included: (1) discrete kinematic and kinetic parameters, and (2) gait deviation index for kinematics (GDI) and kinetics (GDI-k). Results No differences in gait were found between bilateral and unilateral idiopathic clubfoot, but both groups deviated when compared to controls. Compared to control feet, contralateral feet showed no deviations in discrete gait parameters, but discrepancies were evident in relation to unilateral clubfoot, causing gait asymmetries in children with unilateral involvement. However, all groups deviated significantly from control feet according to GDI and GDI-k. Interpretation Bilateral and unilateral idiopathic clubfoot cases show the same persistent deviations in gait, mainly regarding reduced plantarflexion. Nevertheless, knowledge of foot involvement is important as children with unilateral clubfoot show gait asymmetries, which might give an impression of poorer deviations. The results of GDI/GDI-k indicate global gait adaptations of the contralateral foot, so the foot should preferably not be used as a reference for gait. PMID:27331243

    Castleman disease is a non-neoplastic cause of lymphadenopathy, first described in 1956 by Dr. Benjamin Castleman. Orbital involvement in Castleman disease is extremely rare. We report a case of bilateral orbital Castleman disease in a 48-year-old Asian male who presented with bilateral inferior dystopia. MRI revealed bilateral extraconal superior orbital mass. Histopathology and immunohistochemistry of the mass revealed features of Castleman disease of hyaline vascular type. Castleman disease should be a differential in suspected idiopathic orbital inflammatory disease and lymphoproliferative disorders.

A 42-year-old female of Indian origin and 30-year-old female from Somalia both presented with bilateral acute iritis. In the first patient, bilateral ankle edema preceded the onset of bilateral acute iritis. Bilateral ankle edema developed during the course of disease after onset of ocular symptoms in the second patient. Both patients did not suffer any significant ocular problem in the past, and on systemic examination, all clinical parameters were within normal limit. Lacrimal gland and conjunctival nodule biopsy established the final diagnosis of sarcoidosis in both cases, although the chest x-rays were normal.

    Central precocious puberty (CPP) without organic abnormality is called idiopathic CPP (ICPP). The objective of this trial was to evaluate the effects of pomegranate extract in supplementing gonadotropin-releasing hormone (GnRH) analog therapy on ICPP-affected girls in the Chinese population. 286 girls, diagnosed with ICPP were initially enrolled into this trial, and among them 225 eligible patients were randomized to receive a combinational GnRH analog treatment supplemented with either a placebo or pomegranate extract on a daily basis for a period of 3 months. Their demographics, secondary sexual characteristics and hormone profiles were analyzed at baseline and end of trial. After 3 months of treatment, demographic profiles including bone age, growth velocity and height standard deviation score for bone age, and secondary sexual characteristics including uterus and ovary volume, as well as serum hormone profiles including estradiol, peak luteinizing hormone and insulin-like growth factor 1 were all significantly improved in girls receiving a combinational treatment of both GnRH analog and pomegranate extract. Daily consumption of pomegranate extract was able to supplement and improve the treatment outcomes of the GnRH analog therapy for ICPP in Chinese girls.

This review examines the multitude of etiologies of what were once labeled idiopathic pancreatitis and provides the current evidence on each. This review begins with a background review of the current epidemiology of idiopathic pancreatitis prior to discussion of various etiologies. Etiologies of medications, infections, toxins, autoimmune disorders, vascular causes, and anatomic and functional causes are explored in detail. We conclude with management of true idiopathic pancreatitis and a summary of the various etiologic agents. Throughout this review, areas of controversies are highlighted. PMID:18081217

    Idiopathic intracranial hypertension (IIH) is a rare neurological disorder in children. It is characterized by raised intracranial pressure (ICP) in the absence of brain parenchymal lesion, vascular malformations, hydrocephalus, or central nervous system (CNS) infection. The diagnosis is usually confirmed by high opening pressure of cerebrospinal fluid (CSF) with exclusion of secondary causes of intracranial hypertension. If not treated properly, it may lead to severe visual dysfunction. Here we review the etiology, clinical presentation, diagnostic criteria and management of IIH in children through illustration of the clinical and radiological presentation of a 13-year-old overweight girl who presented with severe headache, diplopia and bilateral papilledema. Otherwise, she had unremarkable neurological and systemic examinations. Lumbar puncture showed a high CSF opening pressure (360-540 mmH2O). Her investigations showed normal complete blood count (CBC), normal renal, liver, and thyroid function tests. Cerebrospinal fluid (CSF) and blood chemistry were unremarkable. Magnetic resonant image (MRI) of the brain demonstrated empty sella turcica, tortuous optic nerves, and flattening of the posterior sclera. Magnetic resonant venography (MRV) showed focal narrowing of the distal transverse sinuses and absence of venous sinus thrombosis. She required treatment with acetazolamide and prednisolone. With medical treatment, weight reduction, and exercise, our patient had a remarkable improvement in her symptoms with resolution of papilledema in two months. This review highlights the importance of early recognition and management of IIH to prevent permanent visual loss.

    2012-01-01

    A 62-year-old housewife presented to the chest outpatient department with a history of exertional breathlessness of four-month duration. On general physical examination, clubbing of toes was present with sparing of fingers. Chest examination revealed bilateral basal end inspiratory fine crepitations. A diagnosis of idiopathic pulmonary fibrosis was made on the basis of clinical, spirometric, and high-resolution computed tomography findings. Extensive evaluation could not reveal any cause for the differential clubbing. The unusual distribution of clubbing in a clinical condition, such as idiopathic pulmonary fibrosis, where generalized clubbing is expected can lead to a diagnostic confusion. This can lead to a further burden of investigations on the patient as clubbing being a significant finding cannot be ignored. PMID:23133780

    Two experiments were conducted to examine the performance of normal adults, normal children, and children diagnosed with central auditory dysfunction presumed to involve the interhemispheric pathways on a dichotic digits test in common clinical use for the diagnosis of central auditory processing disorder (CAPD) and its corresponding visual analog. Results of the first experiment revealed a significant right ear advantage (REA) for the dichotic listening task and a left-visual-field advantage (LVFA) for the corresponding visual analog in normal adults and children. In the second experiment, results revealed a significantly larger REA in the children with CAPD as compared to the normal children. Results also revealed a reversed cerebral asymmetry (RVFA) for the children with CAPD on the visual task. Significant cross-modal correlations suggest that the two tasks may reflect, at least in part, similar interhemispheric processing mechanisms in children. Findings are discussed in relation to differential diagnosis and modality-specificity of CAPD.

    Bilateral facial nerve palsy [FNP] is a rare condition. Mostly it is idiopathic. Post traumatic bilateral FNP is even more rare and having unique neurosurgical considerations. Post traumatic delayed presentation of bilateral FNP is socially debilitating and also having diagnostic challenge. Due to lack of facial asymmetry as present in unilateral facial paralysis, it is difficult to recognize. We are presenting a case of delayed onset bilateral FNP who developed FNP after 12 days of head injury with a brief discussion of its diagnostic dilemma and management along with literature review.

    To present the rare case of a young boy with idiopathic intracranial hypertension presenting with bilateral sensorineural hearing loss developing over several months. This was accompanied by headaches, otalgia, tinnitus, and vertigo. Furthermore, we aim to provide a concise review on this matter, as this report represents the second case in literature of pediatric idiopathic intracranial hypertension presenting with hearing loss. Workup of a 9-year-old boy with bilateral sensorineural hearing loss, including (among others) physical examination, audiometry, diagnostic imaging, and lumbar puncture. Physical examination including fundoscopy as well as imaging showed no abnormalities. At presentation, pure tone audiometry revealed bone conduction thresholds of about 30 dB HL in both ears. Two months later, this declined to about 35 dB HL in both ears. Lumbar puncture revealed an increased intracranial pressure. The boy was thus diagnosed with idiopathic intracranial hypertension. After the lumbar puncture, the otological complaints gradually resolved, and the hearing normalized (bone conduction thresholds of 0-5 dB HL). Although rare, sensorineural hearing loss in the pediatric population together with otalgia, tinnitus, and vertigo can be due to idiopathic intracranial hypertension and as such can be reversible. © The Author(s) 2015.

  2. A potential mechanism for the sexual dimorphism in the onset of puberty and incidence of idiopathic central precocious puberty in children: sex-specific kisspeptin as an integrator of puberty signals

    PubMed Central

    2012-01-01

    The major determinants of the variability in pubertal maturation are reported to be genetic and inherited. Nonetheless, nutritional status contributes significantly to this variability. Malnutrition delays puberty whereas obesity has been associated to a rise in Idiopathic Central Precocious Puberty (ICPP) in girls. However, epidemiology data indicate that contribution of obesity to early puberty varies significantly among ethnic groups, and that obesity-independent inheritable genetic factors are the strongest predictors of early puberty in any ethnic group. In fact, two human mutations with confirmed association to ICPP have been identified in children with no history of obesity. These mutations are in kisspeptin and kisspeptin receptor, a ligand/receptor pair with a major role on the onset of puberty and female cyclicity after puberty. Progressive increases in kisspeptin expression in hypothalamic nuclei known to regulate reproductive function has been associated to the onset of puberty, and hypothalamic expression of kisspeptin is reported to be sexually dimorphic in many species, which include humans. The hypothalamus of females is programmed to express significantly higher levels of kisspeptin than their male counterparts. Interestingly, incidence of ICPP and delayed puberty in children is markedly sexually dimorphic, such that ICPP is at least 10-fold more frequent in females, whereas prevalence of delayed puberty is about 5-fold higher in males. These observations are consistent with a possible involvement of sexually dimorphic kisspeptin signaling in the sexual dimorphism of normal puberty and of pubertal disorders in children of all ethnicities. This review discusses the likelihood of such associations, as well as a potential role of kisspeptin as the converging target of environmental, metabolic, and hormonal signals, which would be integrated in order to optimize reproductive function.

    This review describes the clinical findings as well as thes diagnostic and therapeutic options for idiopathic intracranial hypertension (pseudotumor cerebri). Furthermore, the pathophysiological concepts are discussed. Idiopathic intracranial hypertension is characterized by signs and symptoms of raised intracranial pressure with no established pathogenesis. Common symptoms include headaches, visual loss and pulsatile tinnitus. Treatment has two major goals: the alleviation of headaches and the preservation of vision. Weight loss and acetazolamide are the cornerstones in the treatment of the disorder. Drainage of cerebrospinal fluid, optic nerve sheath fenestration and stent angioplasty of a sinus stenosis can be employed in severe cases.

    Pulmonary artery aneurysm (PAA) is an uncommon lesion, which may be associated with different etiologies including congenital cardiovascular diseases, systemic vasculitis, connective tissue diseases, infections, and trauma. Idiopathic PAA is sporadically diagnosed by exclusion of concomitant major pathology. We report a case of a 56-year-old female with an idiopathic pulmonary artery dilatation identified fortuitously by echocardiography and confirmed by contrast-enhanced computed tomography. Neither significant pulmonary valve dysfunction nor pulmonary hypertension and other cardiac abnormalities which might contribute to the PAA development were found. Here, we describe echocardiographic and computed tomography findings and review the literature on PAA management.

    To describe 2 topographic facial pain conditions with the pain clearly localized in the eye (idiopathic ophthalmodynia) or in the nose (idiopathic rhinalgia), and to propose their distinction from persistent idiopathic facial pain. Persistent idiopathic facial pain, burning mouth syndrome, atypical odontalgia, and facial arthromyalgia are idiopathic facial pain syndromes that have been separated according to topographical criteria. Still, some other facial pain syndromes might have been veiled under the broad term of persistent idiopathic facial pain. Through a 10-year period we have studied all patients referred to our neurological clinic because of facial pain of unknown etiology that might deviate from all well-characterized facial pain syndromes. In a group of patients we have identified 2 consistent clinical pictures with pain precisely located either in the eye (n=11) or in the nose (n=7). Clinical features resembled those of other localized idiopathic facial syndromes, the key differences relying on the topographic distribution of the pain. Both idiopathic ophthalmodynia and idiopathic rhinalgia seem specific pain syndromes with a distinctive location, and may deserve a nosologic status just as other focal pain syndromes of the face. Whether all such focal syndromes are topographic variants of persistent idiopathic facial pain or independent disorders remains a controversial issue.

    To study idiopathic granulomatous mastitis with respect to its various clinical features, etiologic factors, treatment modalities and complications. Retrospective study of all patients who were diagnosed with idiopathic granulomatous mastitis from 1(st) January 2006 to 31(st) December 2014 at Kasturba Hospital, Manipal, India (a tertiary care referral centre). The research was performed according to the World Medical Association Declaration of Helsinki. Informed consent was taken from the patient before invasive procedures including surgery. Data was analysed using the Statistical Package for Social Sciences version 16.0 wherever appropriate. 73 patients diagnosed with idiopathic granulomatous mastitis during the time period were included. One patient was a male (1.37%), rest were all females (98.63%). The mean age of presentation was 32.67 years (range 23 to 66 years). 70 patients (95.89%) were parous females. Average duration since last childbirth was 4.6 years (range: 3 months to 33 years). 8 patients (10.95%) were lactating. History of oral contraceptive pill use was present in 40 patients (54.79%). The right breast was affected in 44 patients (60.27%), and the left breast in 29 patients (39.73%). None of the patients had bilateral disease. The most common symptom was a painless lump (61.64%). Rest of the patients (38.36%) presented with features of a breast abscess. 19 out of 39 FNACs done (48.72%) were positive for granulomatous mastitis. 59 were primarily managed surgically (lumpectomy/wide excision-33, incision & drainage-26). One patient was treated primarily with prednisolone. 13 patients did not receive specific treatment, and were only kept on regular follow-up. Patients managed with lumpectomy/wide excision had the least rate of complications & recurrence (18.18%). Patients with idiopathic granulomatous mastitis can present with a wide variety of symptoms which mimic other more common conditions. Surgical management in the form of wide excision appears

    Talon cusp is an uncommon condition often present in the maxillary incisors and mandibular premolars. Morphologically, this anomaly has a well-delineated cusp that extends at least half the distance from the cementoenamel junction or cingulum area to the incisal edge. The alteration can cause clinical problems such as caries or occlusal interference. Management of the talon cusp varies according to the circumstances of the individual case and should be as conservative as possible. Presented is a case of bilateral bifid talon cusp in maxillary central incisors that was successfully managed with conservative therapy.

    Diffusion tensor imaging (DTI) allows the study of white matter microstructure in the central nervous system. The aim of this study was to examine the DTI metrics of the cervical spinal cord and the brainstem up to the midbrain in patients with idiopathic restless legs (RLS) compared to matched healthy controls. DTI analysis of the cervical spinal cord and the brainstem up into the midbrain was performed in 25 patients with idiopathic RLS and 25 matched healthy controls. Data analysis in the brain was performed by voxelwise comparison of fractional anisotropy (FA) maps at group level. Cervical spinal cord data analysis was performed by slicewise analysis of averaged FA values in axial slices along the spinal cord. Voxelwise comparison of FA maps in the brainstem showed significant microstructural alterations in two clusters in the midbrain bilaterally. Slicewise comparison of the FA maps in the cervical spinal cord showed a trend for lower FA values at the level of the second and third vertebra area in the patient sample. The imaging data suggest that significant alterations in the midbrain in RLS can be visualized by DTI and might correlate to a macroscopically subtle process with changes of the tissue microstructure in the corresponding tracts. An additional area of interest is regionally clustered in the upper cervical spinal cord with a tendency toward altered diffusion metrics. These results might be addressed by further studies, e.g., at higher magnetic field strengths. © 2016 Associated Professional Sleep Societies, LLC.

    The natural history of idiopathic pulmonary fibrosis (IPF) has been characterized as a steady, predictable decline in lung function over time. Recent evidence suggests that some patients may experience a more precipitous course, with periods of relative stability followed by acute deteriorations in respiratory status. Many of these acute deteriorations are of unknown etiology and have been termed acute exacerbations of IPF. This perspective is the result of an international effort to summarize the current state of knowledge regarding acute exacerbations of IPF. Acute exacerbations of IPF are defined as acute, clinically significant deteriorations of unidentifiable cause in patients with underlying IPF. Proposed diagnostic criteria include subjective worsening over 30 days or less, new bilateral radiographic opacities, and the absence of infection or another identifiable etiology. The potential pathobiological roles of infection, disordered cell biology, coagulation, and genetics are discussed, and future research directions are proposed. PMID:17585107

    A 31-yr-old Korean woman was presented with 4-month history of bilateral hand swelling and stiffness. On clinical examination, she had a painful synovitis of both hands, wrists, knees and ankles. The radiologic and histological examinations confirmed it with palmar fasciitis and polyarthritis syndrome (PFPAS). PFPAS is an uncommon disorder characterized by progressive flexion contractures of both hands, inflammatory fasciitiis, fibrosis, and a generalized inflammatory arthritis. Although most reported cases of PFPAS have been associated with various malignancies, our patient have not been associated with malignancy during 24 months follow up period from her first symptom onset. Her symptoms were improved with moderate dose of corticosteroid and she is currently taking prednisone 5 mg daily without any evidence for internal malignancy. We present here in a young Korean patient with idiopathic PFPAS who was successfully treated with administration of corticosteroid. PMID:17179702

    With the increase in incidence of ectopic pregnancy over the decades, bilateral ectopic pregnancy is also increasing. It is usually associated with assisted reproductive techniques (ART) but in recent years few cases of spontaneous bilateral ectopic pregnancy have been reported. Gynaecologists should be aware of this and that ultrasonography has limitations in diagnosis. In cases of ectopic pregnancy where contralateral adnexa is not clearly identified on ultrasound and fertility needs to be conserved, patient should be managed by experts in well equipped centres. A case of spontaneous bilateral tubal pregnancy that remained undiagnosed till laparotomy, is described.

    Introduction: Unilateral anterior shoulder dislocation is one of the most common problems encountered in orthopedic practice. However, simultaneous bilateral anterior dislocation of the shoulders is quite rare. Case Presentation: We report a case of a 75-year-old woman presented with simultaneous bilateral anterior shoulder dislocation following a trauma, complicated with a traction injury to the posterior cord of the brachial plexus. Conclusions: Bilateral anterior shoulder dislocation is very rare. The excessive traction force during closed reduction may lead to nerve palsy. Clear documentation of neurovascular status and adequate imaging before and after a reduction should be performed. PMID:25685749

    Unstated and unacknowledged bias has a profound impact on the nature and implementation of integrative education models. Integrative education is the process of training conventional biomedical and traditional Chinese medicine practitioners in each tradition such that patient care may be effectively coordinated. A bilateral education model ensures that students in each tradition are cross-taught by experts from the ‘other’ tradition, imparting knowledge and values in unison. Acculturation is foundational to bilateral integrative medical education and practice. Principles are discussed for an open-minded bilateral educational model that can result in a new generation of integrative medicine teachers. PMID:16786060

    2010-01-01

    Idiopathic juxtafoveolar retinal telangiectasis (IJFT), also known as parafoveal telangiectasis or idiopathic macular telangiectasia, refers to a heterogeneous group of well-recognized clinical entities characterized by telangiectatic alterations of the juxtafoveolar capillary network of one or both eyes, but which differ in appearance, presumed pathogenesis, and management strategies. Classically, three groups of IJFT are identified. Group I is unilateral easily visible telangiectasis occurring predominantly in males, and causing visual loss as a result of macular edema. Group II, the most common, is bilateral occurring in both middle-aged men and women, and presenting with telangiectasis that is more difficult to detect on biomicroscopy, but with characteristic and diagnostic angiographic and optical coherence tomography features. Vision loss is due to retinal atrophy, not exudation, and subretinal neovascularization is common. Group III is very rare characterized predominantly by progressive obliteration of the perifoveal capillary network, occurring usually in association with a medical or neurologic disease. This paper presents a current review of juxtafoveolar retinal telangiectasis, reviewing the classification of these entities and focusing primarily on the two most common types encountered in clinical practice, i.e., groups I and II, describing their clinical features, histopathology, natural history, complications, latest results from imaging modalities and functional studies, differential diagnosis, and treatment modalities.

    2017-02-23

    Idiopathic pulmonary fibrosis is a fibrosing interstitial pneumonia associated with the radiological and/or histological pattern of usual interstitial pneumonia. Its aetiology is unknown, but probably comprises the action of endogenous and exogenous micro-environmental factors in subjects with genetic predisposition. Its diagnosis is based on the presence of characteristic findings of high-resolution computed tomography scans and pulmonary biopsies in absence of interstitial lung diseases of other aetiologies. Its clinical evolution is variable, although the mean survival rate is 2-5 years as of its clinical presentation. Patients with idiopathic pulmonary fibrosis may present complications and comorbidities which modify the disease's clinical course and prognosis. In the mild-moderate disease, the treatment consists of the administration of anti-fibrotic drugs. In severe disease, the best therapeutic option is pulmonary transplantation. In this paper we review the diagnostic and therapeutic aspects of the disease.

    2006-01-01

    The therapeutic effects of splenectomy in 15 patients with idiopathic hypersplenism were studied. The mean age was 43 years (range, 5-72 years). The male to female ratio was 1:1.14. The response to splenectomy was: in thrombocytopenia, complete response (CR) in 71%, partial response (PR) and no response (NR) in 14% each of patients; in anemia, CR in 83%, PR in 0%, and NR in 16% of patients; and in leukopenia, CR in 78% and PR and NR in 11% each of patients. However, the morbidity (27%) and mortality (20%) observed was quite high. Thus, we conclude that splenectomy is an excellent treatment to improve the hematological parameters in patients with idiopathic hypersplenism, but elderly patients and patients with multisystem disease should not have this surgery.

  9. Idiopathic pain and depression.

    This report summarizes research on the hypothesis that idiopathic chronic pain syndromes and depressive disorders share certain common pathogenetic mechanisms. There is increasing evidence that this may be partly true. Not only do chronic pain syndromes respond to treatment with antidepressants, but there are also striking clinical similarities between these syndromes and depressive syndromes. However, important differences do exist (e.g., the courses of these disorders are usually dissimilar). Family studies show that affective disorders are common in first-degree relatives of patients with idiopathic pain syndromes, but it is impossible to conclude from this that clear-cut genetic factors are of importance. Factors common to both syndromes include common personality traits, shortened rapid eye movements in sleep EEG, hypercortisolaemia and pathological dexamethasone suppression tests, low levels of melatonin in serum and urine and high levels of endorphins and Fraction I in cerebro-spinal fluid. One important common pathogenetic mechanism seems to be disturbances in the serotoninergic system.

    PubMed

    2016-12-01

    Adolescent idiopathic scoliosis is a 3D spinal deformity in frontal, sagittal and axial planes, with high relevance in the pediatric population especially in adolescents and females between 10 years of age and the end of growth spurt and skeletal maturity. The radiographic manifestation is a curve greater than 10° measured by Cobb method associated with vertebral rotation. "Idiopathic" diagnosis has to be done after neuroanatomical anomalies of the posterior cerebral fosa and spinal canal have been ruled out. The physical finding of a thoracic or lumbar hump is the clinical manifestation of vertebral rotation seen in a forward bending test (Adam's Test). It is recommended that all curves with a magnitude greater than 20° have to be controlled and treated by a spinal surgeon being observation, bracing and surgery the different treatment options based on the extent, progression of deformity and basically the clinical condition of the patient.

    A 57-year-old woman underwent an enucleoresection of her right kidney angiomyolipoma. Two weeks later she was admitted to our hospital because of dyspnea at rest with orthopnea. The chest x-ray showed the elevation of both hemidiaphragms and the measurement of the sniff transdiaphragmatic pressure confirmed the diagnosis of bilateral diaphragmatic paralysis. A diaphragm paralysis can be ascribed to several causes, i.e. trauma, compressive events, inflammations, neuropathies, or it can be idiopathic. In this case, it was very likely that the patient suffered from post-surgery neuralgic amyotrophy. To our knowledge, there are only a few reported cases of neuralgic amyotrophy, also known as Parsonage-Turner Syndrome, which affects only the phrenic nerve as a consequence of a surgery in an anatomically distant site.

    The bilateral lateral periodontal cyst is a rare nasological entity, which despite clinical and radiological presentation is being diagnosed by histological characteristics. It is asymptomatic in nature and is observed in routine radiography. The aim and objective of this article is to present a rare case of bilateral lateral periodontal cyst in a 14-year-old child. The clinical and radiographical findings, along with its management have been discussed. Enucleation of bilateral cyst without extraction of the adjacent tooth was performed. Lesion samples were sent for histopathological analysis. The histopathological analysis revealed a thin, non keratinised stratified squamous epithelium resembling reduced enamel epithelium. Epithelial plaques were also seen. A clinicopathological correlation incorporating the surgical, radiographical and gold standard histopathological findings was obtained to suggest the final diagnosis of the bilateral lateral periodontal cyst.

    We report the clinical findings of a patient with severe bilateral keratectasia 34 years after a penetrating keratoplasty (PK) in both eyes. An otherwise healthy 67-year-old man complained of deterioration of the eyesight in both eyes over the last 6 months. The patient was diagnosed with bilateral keratoconus at the age of 32 years, and he underwent a bilateral PK. At presentation, visual acuity was 20/200 in the right eye and light perception in the left eye. A Pentacam pachymetric map revealed a central pachymetry of 720 μm in the right eye and of 710 μm in the left eye, as well as an average paracentral pachymetry of 436 and 270 μm in the 9-mm zone in the right and the left eye, respectively. Corneal topography revealed bilateral irregular and asymmetric bowing with generalized steepening and high corneal power. We describe a case of bilateral keratectasia 34 years after PK in a patient who was originally diagnosed with bilateral keratoconus. PMID:20737056

    Background: Calcinosis cutis—the deposition of insoluble calcium salts in the skin and the soft tissue—occurs in the following five settings: calciphylaxis, dystrophic, iatrogenic, idiopathic, and metastatic. Idiopathic calcinosis cutis of the penis is rare. Purpose: This paper describes a man with idiopathic calcinosis cutis of the penis, summarizes the clinical features of previously reported men with this condition, and also reviews dystrophic, iatrogenic, and metastatic penile calcinosis. Methods: A 27-year-old Pakistan man presented with concurrent, asymptomatic, individual nodules on the right mid-ventral penile shaft and left side of scrotum and two additional papules on the right side of the scrotum. Evaluation and treatment included the excision of all lesions. Reports of patients with penile calcinosis were identified using a medical search engine (PubMed Central) and referenced citations from the published papers on this subject. Results: Microscopic examination of the patient's nodules showed idiopathic and dystrophic calcinosis cutis of the penis and scrotum, respectively; the scrotal papules were fibroepithelial polyps. Including this individual, idiopathic calcinosis cutis of the penis has only been reported in 11 men. It presents as either an asymptomatic nodule (5 patients) or multiple lesions (6 patients) of less than one-year duration, on either the penile shaft (distal in 4 patients, mid in 2 patients, both in 1 patient, and site unspecified in 1 patient) or the prepuce (3 patients) of uncircumcised men less than 30 years of age. Concurrent scrotal calcification was noted in two patients. Dermal deposits of calcium are found in the dermis—often with surrounding histiocytes and multinucleated giant cells; concurrent features of dystrophic penile shaft calcification, such as calcium within syringomas or transepidermal elimination of calcium through eccrine sweat ducts, was only noted in two men. The nodules do not recur following excision

    Bilateral facial palsy is a rare clinical entity caused by myriad disparate conditions requiring different treatment paradigms. Lyme disease, Guillain-Barré syndrome, and leukemia are several examples. In this article, the authors describe the cause, the initial diagnostic approach, and the management of long-term sequelae of bilateral paralysis that has evolved in the authors' center over the past 13 years. A chart review was performed to identify all patients diagnosed with bilateral paralysis at the authors' center between January of 2002 and January of 2015. Demographics, signs and symptoms, diagnosis, initial medical treatment, interventions for facial reanimation, and outcomes were reviewed. Of the 2471 patients seen at the authors' center, 68 patients (3 percent) with bilateral facial paralysis were identified. Ten patients (15 percent) presented with bilateral facial paralysis caused by Lyme disease, nine (13 percent) with Möbius syndrome, nine (13 percent) with neurofibromatosis type 2, five (7 percent) with bilateral facial palsy caused by brain tumor, four (6 percent) with Melkersson-Rosenthal syndrome, three (4 percent) with bilateral temporal bone fractures, two (3 percent) with Guillain-Barré syndrome, one (2 percent) with central nervous system lymphoma, one (2 percent) with human immunodeficiency virus infection, and 24 (35 percent) with presumed Bell palsy. Treatment included pharmacologic therapy, physical therapy, chemodenervation, and surgical interventions. Bilateral facial palsy is a rare medical condition, and treatment often requires a multidisciplinary approach. The authors outline diagnostic and therapeutic algorithms of a tertiary care center to provide clinicians with a systematic approach to managing these complicated patients.

    1997-11-01

    We reported a 67-year-old woman with bilateral caudate head infarcts. She developed sudden mutism followed by abulia. She was admitted to our hospital 2 months after ictus for further examination. She showed prominent abulia and was inactive, slow and apathetic. Spontaneous activity and speech, immediate response to queries, spontaneous word recall and attention and persistence to complex programs were disturbed. Apparent motor disturbance, gait disturbance, motor aphasia, apraxia and remote memory disturbance were not identified. She seemed to be depressed but not sad. Brain CT and MRI revealed bilateral caudate head hemorrhagic infarcts including bilateral anterior internal capsules, in which the left lesion was more extensive than right one and involved the part of the left putamen. These infarct locations were thought to be supplied by the area around the medial striate artery including Heubner's arteries and the A1 perforator. Digital subtraction angiography showed asymptomatic right internal carotid artery occlusion. She bad had hypertension, diabetes mellitus and atrial fibrillation and also had a left atrium with a large diameter. The infarcts were thought to be caused by cardioembolic occlusion to the distal portion of the left internal carotid artery. Although some variations of vasculature at the anterior communicating artery might contribute to bilateral medial striate artery infarcts, we could not demonstrate such abnormalities by angiography. Bilateral caudate head infarcts involving the anterior internal capsule may cause prominent abulia. The patient did not improve by drug and rehabilitation therapy and died suddenly a year after discharge.

  1. Unusual Presentation of Type 1 Idiopathic Macular Telangiectasia

    PubMed Central

    Denis, Philippe

    2017-01-01

    Purpose. To report unusual presentation of type 1A idiopathic macular telangiectasia (IMT). Methods. Two middle-aged women with bilateral IMT were examined. Results. Both patients presented with a gradual vision loss in both eyes. Fundus examination was unremarkable in one case and showed small macular telangiectasia in both eyes in the other case. Fluorescein angiography (FA) revealed early bilateral macular punctuated hyperfluorescence corresponding to the dilated capillaries in both cases. FA and fundus examination confirmed also the absence of vascular abnormalities in the middle or anterior fundus periphery in one case. Spectral-domain optical coherence tomography (SD-OCT) showed cystoid macular edema in both cases. No signs of retinal vein occlusions were detected in both cases and other differential diagnoses were excluded. Based on these findings, the patients were diagnosed with bilateral type 1A IMT according to Gass and Blodi classification and were treated with intravitreal antivascular endothelial growth factor (anti-VEGF) injections and focal laser photocoagulation. Twelve months later, SD-OCT revealed partial regression of the exudative signs and significant VA improvement. Conclusion. We described two patients with an unusual presentation of type 1A IMT with bilateral presentation, affecting two middle-aged women, with occult and without peripheral involvement in one case. The description of more cases of bilateral type 1 IMT should be helpful to more precisely define the pathophysiologic mechanism that could be different from a localized Coats' disease of the macula area.

    Simultaneous or subsequent bilateral thalamic haemorrhage is rare, and most reported cases are from Asian countries. An 80-year-old white Cuban man, with a history of arterial hypertension, suffered sudden onset of right hemiparesis. Computed tomography (CT) scan showed a left posteromedial thalamic haemorrhage. Two days later his condition suddenly deteriorated: blood pressure was 220/105 mm Hg, he was stuporous and tetraplegic, respiration was ataxic, and his gaze was fixed and deviated downward and inward. CT scan showed haemorrhages in both thalami, extending to the ventricles. 32 h later the patient died. There are few previous publications of simultaneous or subsequent bilateral thalamic haemorrhages and this is the first report involving a Hispanic patient. Prognosis in patients with bilateral thalamic haemorrhage is poor, and the mechanism underlying the development of subsequent and symmetrical bleeding is not clear. PMID:21709830

    Idiopathic gingival fibromatosis (IGF) is a rare hereditary condition characterized by slowly progressive, nonhemorrhagic, fibrous enlargement of maxillary and mandibular keratinized gingiva caused by increase in submucosal connective tissue elements, mostly associated with some syndrome. This case report describes a case of nonsyndromic generalized IGF in an 18-year-old male patient who presented with generalized gingival enlargement. The enlarged tissue was surgically removed by internal bevel gingivectomy and ledge and wedge procedure. The patient was regularly monitored clinically for improvement in his periodontal condition as well as for any recurrence of gingival overgrowth. PMID:26941525

    Idiopathic granulomatous orchitis is a rare inflammatory process of the testis of unknown etiology. It is characterized by presence of non-specific granulomatous inflammation and admixed multinucleated giant cells. It usually presents as a testicular mass which is highly suspicious of malignancy. Histologically, there is extensive destruction of seminiferous tubules with tubular or interstitial pattern of granulomatous inflammation and prominent collagen fibrosis. Trauma and possible auto-antibodies against sperms have been postulated to be the underlying mechanism. Differential diagnoses include intratubular germ-cell neoplasia, malignant lymphomas, and malakoplakia. Orchiectomy is currently the most appropriate therapy for this condition.

  6. Adolescent Idiopathic Scoliosis

    Choudhry, Muhammad Naghman; Ahmad, Zafar; Verma, Rajat

    2016-01-01

    Background: Scoliosis refers to deviation of spine greater than 10 degrees in the coronal plane. Idiopathic Scoliosis is the most common spinal deformity that develops in otherwise healthy children. The sub types of scoliosis are based on the age of the child at presentation. Adolescent idiopathic scoliosis (AIS) by definition occurs in children over the age of 10 years until skeletal maturity. Objective: The objective of this review is to outline the features of AIS to allow the physician to recognise this condition and commence early treatment, thereby optimizing patient outcome. Method: A thorough literature search was performed using available databases, including Pubmed and Embase, to cover important research published covering AIS. Conclusion: AIS results in higher incidence of back pain and discontent with body image. Curves greater than 50 degrees in thoracic region and greater than 30 degrees in lumbar region progress at a rate of 0.5 to 1 degree per year into adulthood. Curves greater than 60 degrees can lead to pulmonary functional deficit. Therefore once the disease is recognized, effective treatment should be instituted to address the deformity and prevention of its long-term sequelae. PMID:27347243

    2016-05-01

    Pityriasis lichenoides is an uncommon, acquired, idiopathic, self-limiting skin disease that poses a challenge to patients and clinicians to diagnose and treat. Several variants exist including pityriasis lichenoides et varioliformis acuta (PLEVA), pityriasis lichenoides chronica (PLC), and febrile ulcer-onecrotic Mucha-Habermann disease. Precise classification can be difficult due to an overlap of clinical and histologic features. In this case report we describe a patient with a rare presentation of PLC exhibiting bilateral palmoplantar involvement and mimicking psoriasis. We review the literature and discuss the clinical course, pathogenesis, and current treatment modalities of PLC.

  9. Idiopathic erythermalgia: a congenital disorder.

    PubMed

    1989-11-01

    Idiopathic erythermalgia during early childhood and adolescence is characterized by red, congested, burning pain of the lower extremities provoked by exercise or exposure to warmth. The clinical symptoms of idiopathic erythermalgia in a young woman and her mother are described. Histopathologic and immunofluorescence findings in biopsy specimens of affected areas of skin were consistent with a nonspecific inflammatory process. The condition was completely refractory to any treatment. Even the long-lasting relief of pain with one low dose of aspirin, which is a prerequisite for the diagnosis of thrombocytemic erythromelalgia, was lacking. Idiopathic erythermalgia appears to be a separate clinical entity and congenital disorder.

    Objectives This report describes the case of a patient with chronic idiopathic meralgia paresthetica associated with bilateral sacroiliac joint dysfunction who was managed with chiropractic care. Clinical Features A 35-year-old white woman presented to a private chiropractic clinic with a complaint of numbness in the right anterolateral thigh region. Neurological assessment revealed a diminution of sensibility and discrimination on the right lateral femoral cutaneous nerve territory. Pain was rated as 8.5 on a numeric pain scale of 0 to 10. Musculoskeletal examination of the pelvic region disclosed bilateral sacroiliac joint dysfunction. Intervention and Outcomes Chiropractic management included pelvic mobilizations, myofascial therapy, transverse friction massage, and stretching exercises. After 3 visits (2 weeks later), result of neurological evaluation was normal, with no residual numbness over the lateral thigh. Conclusion In the present case, chiropractic management with standard and applied kinesiology techniques resulted in recovery of meralgia paresthetica symptoms for this patient. PMID:22942840

    Our aim was to clarify the correlation of attention deficit hyperactivity disorder (ADHD) with epilepsy and behavior problems. This was a cross-sectional study. Sixty children with idiopathic epilepsy were interviewed using the MTA-SNAP IV Teacher and Parent Rating Scale, Vineland Adaptive Behavior Scales and Conners' Rating Scales. We used the chi-square test to analyze the correlation of epilepsy variables in patients with and without ADHD with a significance level of 0.05. Eight patients had ADHD symptoms (13%), seven had the inattentive ADHD subtype and only three had behavioral problems. When epileptic patients with and without ADHD symptoms were compared we found no significant difference in regard to epilepsy variables. All patients were controlled and 43% were either without AED or undergoing withdrawal. Our study revealed a low comorbidity of ADHD symptoms and epilepsy due to low interference of seizures and drug treatment on the comorbid condition.

    2008-11-01

    Idiopathic pulmonary fibrosis is a chronic disorder characterized histopathologically by a pattern of usual interstitial pneumonia, with heterogeneous and mutilating interstitial fibrosis with foci of proliferating fibroblasts, honeycomb lung, and little if any inflammation. The diagnosis is based on a pluridisciplinary analysis of the clinical symptoms, the chest high-resolution computerized tomography features, and pathology on video-thoracoscopic lung biopsy when indicated. In half of the cases, the typical tomodensitometric pattern allows to make a confident diagnosis without a lung biopsy. The median survival is only about 3 years and is presently not improved by any treatment. Treatment with N-acetylcysteine (antioxydant) in association with corticosteroids and azathioprine may slightly reduce the rate of functional worsening. Clinical trials are in progress to improve the treatment of this still incurable disease.

In addition to weight loss, anaemia, amenorrhoea, general lethargy, anorexia, mouth ulcers, blisters of hands and feet, and petechial skin rash, she had features of involvement of the cardiovascular system as the major complication. She responded well to treatment. After a comprehensive search of the published reports 18 cases of this syndrome were identified in children under 16 years. Fifteen of these children had involvement of the cardiovascular system as the major source of their morbidity and mortality. Summary of the clinical details and laboratory, biopsy, and necropsy findings of the involvement of the various organ systems of the 18 children is presented. PMID:3619478

    Idiopathic normal pressure hydrocephalus (iNPH) is a potentially reversible neurodegenerative disease commonly characterized by a triad of dementia, gait, and urinary disturbance. Advancements in diagnosis and treatment have aided in properly identifying and improving symptoms in patients. However, a large proportion of iNPH patients remain either undiagnosed or misdiagnosed. Using PubMed search engine of keywords “normal pressure hydrocephalus,” “diagnosis,” “shunt treatment,” “biomarkers,” “gait disturbances,” “cognitive function,” “neuropsychology,” “imaging,” and “pathogenesis,” articles were obtained for this review. The majority of the articles were retrieved from the past 10 years. The purpose of this review article is to aid general practitioners in further understanding current findings on the pathogenesis, diagnosis, and treatment of iNPH. PMID:28138494

    Purpose Orbicularis weakness is commonly associated with seventh nerve palsy or neuromuscular and myopathic conditions such as myotonic dystrophy and myasethenia gravis. We report four cases of idiopathic isolated orbicularis weakness. Methods All four cases were female and the presenting symptoms of ocular irritation and epiphora had been present for over 7 years in three patients. All patients had lagophthalmos and three had ectropion. Three patients underwent full investigations which excluded known causes of orbicularis weakness. Two patients underwent oribularis oculi muscle biopsy and histological confirmation of orbicularis atrophy. Results All patients underwent surgery to specifically address the orbicularis weakness with satisfactory outcomes and alleviation of symptoms in all cases. Isolated orbicularis weakness may be a relatively common entity that is frequently overlooked. Conclusion Early recognition of this condition may lead to better management and prevent patients undergoing unnecessary surgical procedures. PMID:22322997

    Juvenile Idiopathic Arthritis (JIA) is the most chronic musculoskeletal disease of pediatric population. The chronic course of disease has a great impact on oral health. Temporomandibular joint is involved in JIA causing limited mouth opening with progressive open bite, retrognathia, microgenia and bird like appearance. Joints of upper and lower extremities are also involved. Effect on upper limb function leads to difficulty with fine motor movements required for brushing and flossing. This increases incidence of caries and periodontal disease in children. The cause of JIA is still poorly understood and none of the available drugs for JIA can cure the disease. However, prognosis has improved as a result of progress in disease classification and management. The dental practitioner should be familiar with the symptoms and oral manifestations of JIA to help manage as multidisciplinary management is essential.

  18. Ablation of idiopathic ventricular tachycardia.

    PubMed

    Schreiber, Doreen; Kottkamp, Hans

    2010-09-01

    Idiopathic ventricular arrhythmias occur in patients without structural heart disease. They can arise from a variety of specific areas within both ventricles and in the supravalvular regions of the great arteries. Two main groups need to be differentiated: arrhythmias from the outflow tract (OT) region and idiopathic left ventricular, so-called fascicular, tachycardias (ILVTs). OT tachycardia typically originates in the right ventricular OT, but may also occur in the left ventricular OT, particularly in the sinuses of Valsalva or the anterior epicardium or the great cardiac vein. Activation mapping or pace mapping for the OT regions and mapping of diastolic potentials in ILVTs are the mapping techniques that are typically used. The ablation of idiopathic ventricular arrhythmias is highly successful, associated with only rare complications. Newly recognized entities of idiopathic ventricular tachycardias are those originating in the papillary muscles and in the atrioventricular annular regions.

    Objective: The purpose of this study was to analyze the efficacy and safety of the 585nm pulsed dye laser for the treatment of idiopathic flushing with dysesthesia. Design: This was a retrospective study of patients treated with a 585nm pulsed dye laser with fluences ranging from 3.5 to 7.5J/cm2 (purpura threshold fluences), a pulse duration of 450μsec, and a spot size of 5 or 10mm. Setting: The Ronald 0. Perelman Department of Dermatology at New York University Medical Center. Participants: Ten adult subjects who presented with flushing with dysesthesia. Measurements: Participants subjectively evaluated the decrease in dysesthesia and the number of flushing episodes. The objective response to treatment was evaluated by a single physician using pre- and postoperative photographs. The severity of postoperative erythema was compared with baseline using an ordinal scale ranging from zero (resolution of erythema) to four (76-100% of baseline erythema). Results: The mean number of treatments received by the subjects was seven. The mean fluence was 6.66J/cm2. Subjectively, 100 percent of subjects reported a decrease in dysethesia and the number of flushing episodes. Objectively, subjects demonstrated at least a 62.5-percent reduction in erythema. Conclusion: Laser surgery provided subjective relief of dysesthesia and decreased the number of flushing episodes with a greater than 62-percent objective reduction in the severity of erythema. The 585nm pulsed dye laser is a safe, efficacious treatment for the signs and symptoms of idiopathic flushing with dysesthesia. PMID:26345489

    Wolf, S R

    1998-09-01

    Although acute idiopathic facial paresis is often labelled "Bell's palsy", historical studies show that Nicolaus Anton Friedreich (1761-1836) from Würzburg was the first physician to describe the typical symptoms of the disorder in 1797, approximately 24 years prior to the paper published by Sir Charles Bell. Diagnostics has now improved to the extent that acute idiopathic facial palsy can more frequently be assigned to etiologies caused by inflammatory disorders. Herpes simplex virus type I and Borrelia burgdorferi are particularly relevant. Underestimation of the degree of paresis is, particularly in children, a drawback of the clinical examination. "Incomplete eyelid closure" is not a reliable indicator of remaining nerve function. For this reason complete electromyography (EMG) is recommended in all cases of severe facial paresis. Since electroneurography does not reliably reflect the degree of denervation present, needle EMG is preferred. The therapy of the facial palsy of unclear etiology is still not well defined. Nevertheless, we recommend that a combined treatment should be used early, at least in patients with disfiguring pareses. Combinations may consist of cortisone, virostatic agents and hemorrheologic substances and possibly antibiotics. Surgical decompression of the facial nerve remains controversial, since positive surgical results lack statistical support. Individual instructions for facial exercises, massage and muscle relaxation can support rehabilitation and possibly reduce the production of pathological synkinesia. Electrical stimulation should not be used. There are a number of possibilities available to reduce the effects of misdirected reinnervation, especially the use of botulinum-A-toxin. However, intensive diagnosis and therapy in the early phase of paresis are decisive in obtaining a favorable outcome. Further refinements in rehabilitation and comparative multicenter controlled studies are still required for future improvements in

    The surgeon's objectives are normal nasolabial appearance and normal speech. The principles for synchronous repair of bilateral cleft lip have been established, and the techniques continue to evolve. Primary repair impairs maxillary growth, but little can be done at this time except to practice gentle craftsmanship and to minimize tension on the lower labial closure. The cutaneous lip should never be reopened for revision, and the number of secondary procedures involving the nasal cartilages should be kept to a minimum. Many adolescents with repaired bilateral cleft lip need maxillary advancement to improve projection of the nasal tip, to protrude the upper lip, and to attain normal sagittal skeletal harmony. With expected improvements in the technology of distraction osteogenesis, maxillary advancement may someday become as acceptable as orthodontic treatment.

    The author reports the case of a well and fit patient who presented herself to the emergency department and was found to have bilateral emphysematous pyelonephritis. She was admitted to the intensive care where she was initially treated conservatively with antibiotics, percutaneous drainage and continuous renal replacement therapy, but her condition deteriorated. She underwent a left total nephrectomy and a partial right nephrectomy that resulted in remarkable improvement. The patient started passing urine spontaneously, so no haemofiltration was required. She was discharged home and her case was followed-up by an urologist and nephrologist. This case lays emphasis on thoroughly investigating and managing a patient with bilateral emphysematous pyelonephritis and, in relation to its management, on the dilemma of whether the treatment of choice should be conservative or surgical.

    Congenital absence of tibia is a rare anomaly. We report a case of bilateral tibial hemimelia born to phenotypically normal parents. The two amputated legs with tibial dysplasia obtained from a 3-year-old boy were studied by radiography and anatomical dissection. The radiological evaluation revealed a normal hip joint. The lower end of femur was normal without any bifurcation, shortening or bowing. Fibula was present on both legs and there was no sign of bowing or doubling. Both right and left tibiae were absent. In addition, on the right side, five tarsal bones, two metatarsals and the corresponding digital rays were absent. On the left side, three tarsal bones were absent. Dissection of the amputated segments showed the presence of extensor digitorum longus, peroneus tertius, peroneus longus and brevis, gastrocnemius, and soleus. Following bilateral knee disarticulation the patient was fitted with prosthesis and is doing well.

    Twenty children with bilateral Wilms' tumor were presented to the Children's Hospital Medical Center and Children's Cancer Research Foundation, Sidney Farber Cancer Institute, and Joint Center for Radiation Therapy (CHMC-CCRF, SFCI, JCRT) from January 1, 1956 to December 31, 1976. Of these 20, 16 had simultaneous and 4 had metachronous disease on presentation. All patients were treated with surgery, radiation and chemotherapy. Of the 16 patients with simultaneous disease, 10 (63%) are alive and free of disease 12+ to 175+ months post diagnosis and treatment, with median follow-up of 121 months. There were no long-term survivors in the metachronous group; all were dead of disease within 21 months from initial presentation of original tumor. With these data we relate prognosis to extent of disease and discuss a general approach to the management of bilateral Wilms' tumor.

    The diagnosis of idiopathic pulmonary fibrosis can be quite challenging, even after careful clinical evaluation, imaging and pathological tests. This case report intends to demonstrate and discuss these difficulties, especially those concerning the differential diagnosis with chronic hypersensitivity pneumonitis. A 58-year-old white male presented with shortness of breath, dry cough, fatigue and weight loss for two months. He was a former smoker and had regular exposure to a parakeet and poultry. Physical examination revealed bilateral basal crackles and chest imaging showed subpleural cystic lesions and traction bronchiectasis with a right side and upper level predominance. Auto-antibodies and IgG immunoglobulins to parakeet and fungal proteins were negative. Lung function tests displayed moderate restriction, low diffusion capacity and resting hypoxaemia. Bronchoalveolar lavage showed increased lymphocytes (28%) and neutrophils (12%) and surgical lung biopsy was compatible with a pattern of usual interstitial pneumonia. According to the possibility of either idiopathic pulmonary fibrosis or chronic hypersensitivity pneumonitis, treatment included prednisolone, azathioprine, acetylcysteine and avoidance of contact with the parakeet, but there was an unfavorable response and the patient was subsequently referred for lung transplant. Chronic hypersensitivity pneumonitis and idiopathic pulmonary fibrosis can present with the same clinical and radiological manifestations In this case, despite careful evaluation, no definite diagnosis could be achieved.

    Idiopathic intracranial hypertension is a disorder characterised by increased intracranial pressure without evidence of an expansive intracranial process or cerebrospinal fluid cytochemical alterations. We reviewed the medical records of patients with idiopathic intracranial hypertension admitted to our hospital between 1999 and 2009 and who met the modified Dandy criteria. We collected the following data: age, body mass index (BMI), outlet pressure of cerebrospinal fluid, cardiovascular history, imaging studies, treatment, and outcome. We analysed 61 patients (19 males and 42 females) with a mean age of 35.38 years. A BMI above the normal range was determined for 72.13% of the patients, although 47.37% of males showed normal weight. Fifty per cent of patients had a cardiovascular risk factor, especially dyslipidaemia, hypertension, and contraceptive drugs in women. Headache was the main presenting symptom, followed by visual field defects and other visual disturbances. Bilateral papilledema was present in 81.96% of the patients. The approximate incidence is 1.2/100,000 individuals/year. The condition is more common in young women with higher body weight and it is also associated with contraceptive drugs. Headache with bilateral papilloedema and impaired visual acuity stand out as the main symptoms. An interesting finding from this study is that male patients had a lower BMI, a lower incidence of headache and increased visual impairment. Copyright © 2012 Sociedad Española de Neurología.

    We described a 15-year-old girl who presented with persistent fever, bilateral flank pain, and worsening dyspnea. The peripheral blood cell count showed remarkable eosinophilia at the time of admission. Severe pleural effusion with eosinophilic Infiltrations as well as pericardial effusion were noted thereafter. Bone marrow examination disclosed markedly increased eosinophils. Bilateral ectasia of the renal pelvis was found in an ultrasonographic study of the kidneys. Spiking fever and progressive shortness of breath persisted despite treatment with empiric antibiotics for infection. Based on the clinical course and histological findings, a tentative diagnosis of idiopathic HES was made. After treatment with oral prednisolone daily (1 mg/kg/day) for one week, there was a rapid improvement in her clinical condition. She was discharged a few days later and the steroids were withdrawn gradually when she was asymptomatic. The absolute eosinophil count (AEC) was monitored during follow-up. At 3 weeks, the AEC had fallen from 8,060/mm3 to 4,792/mm3 and it further fell to 1,591/mm3 at 5 months, and to 855/mm3 at 8 months during follow-up. There is no evidence of any other organ involvement until now. The clinical manifestations, diagnosis and management of idiopathic HES in children are also reviewed.

    Tarsal tunnel syndrome (TTS) is one of the frequently encountered entrapment neuropathies of the lower limb. Most often the aetiology is considered to be idiopathic. However, it has to be thoroughly investigated to rule out diverse extrinsic and intrinsic causes. The sustentaculum tali (ST) forms the superior part of the distal tarsal tunnel, and any increase in its size may result in irritation of the tibial nerve or its branches, the medial and lateral plantar nerves or decrease the overall volume of the tarsal tunnel culminating to clinical features of TTS. A hypertrophied ST is an extremely rare cause for TTS, and we report perhaps a first case of bilateral TTS in a young adult due to bilateral symmetrical hypertrophied ST which in turn was a result of bilateral fibrous tarsal coalition. Staged bilateral surgical excision of the hypertrophied part of ST and the underlying fibrous tarsal coalition ensured prompt symptomatic relief. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Idiopathic pulmonary fibrosis (IPF), the most prevalent of the idiopathic interstitial pneumonias, is associated with a poor prognosis. An accurate diagnosis of IPF is essential for its optimal management. The 2011 American Thoracic Society (ATS)/European Respiratory Society (ERS)/Japanese Respiratory Society (JRS)/Latin American Thoracic Association (ALAT) recommendations on the diagnosis and management of IPF were developed from a systematic review of the published literature. High-resolution computed tomography (HRCT) scanning has a central role in the IPF diagnostic pathway, with formal designation of criteria for an HRCT pattern of usual interstitial pneumonia. In the correct clinical context, a usual interstitial pneumonia pattern on HRCT is indicative of a definite diagnosis of IPF and negates the need for a surgical lung biopsy. However, although the 2011 ATS/ERS/JRS/ALAT statement is a major advance, the application of the guideline recommendations by clinicians has identified limitations that should be addressed in future statements. Key problems include: 1) HRCT misdiagnosis, particularly by less experienced radiologists; 2) lack of management recommendations for the highly prevalent clinical scenarios of "probable" or "possible" IPF; 3) ongoing confusion concerning the diagnostic role of bronchoalveolar lavage; and 4) the lack of integration of clinical data in the designation of the diagnostic likelihood of IPF, including the treated course of disease. These issues become evident as the recommendations are applied and highlight the need for continued guideline adjustments.

    Opercular syndrome, also known as Foix-Chavany-Marie syndrome, is a paralysis of the facial, pharyngeal, masticatory, tongue, laryngeal, and brachial muscles. It is a rare cortical form of pseudobulbar palsies caused by vascular insults to bilateral operculum. Its clinical presentations include anarthria, weakness of voluntary muscles involving face, tongue, pharynx, larynx, and masticatory muscles. However, autonomic reflexes and emotional activities of these structures are preserved. In the present case, an 81-year-old male presented with acute onset of anarthria with difficulties in chewing, speaking, and swallowing that was diagnosed with opercular syndrome.

    The objective of the study was to determine bilateral caries occurrence or caries bilaterality in preschool children of Riyadh. For this purpose, 789 randomly selected preschool children, 379 (48%) boys and 410 (52%) girls, were examined for dental caries utilizing the World Health Organization (WHO) criteria for diagnosis of dental caries. Caries were significantly bilateral (p < .05) in all the teeth. Among the posterior teeth, mandibular second molars showed the highest caries bilaterality (88%) and among the anterior teeth, maxillary central incisors had the highest caries bilaterality (88.9%). Mandibular canines had the lowest caries bilaterality (52.7%). There was more than 50% probability of left side tooth being carious given that right side tooth was carious for all the teeth. Amongst posterior teeth, the conditional probability for bilateral caries occurrence was highest in mandibular second molars (.88) and amongst the anterior teeth, maxillary central incisors had the highest conditional bilaterality (.89). Caries bilaterality was significantly high (p < .05) in children with poor and fair oral hygiene as compared to children with good oral hygiene for all the molars and maxillary central incisors. It can be concluded that bilateral caries occurrence or caries bilaterality is highly prevalent in all the primary teeth; especially in mandibular molars and maxillary incisors.

  19. Adolescent Idiopathic Scoliosis

    1988-01-01

    Adolescent idiopathic scoliosis is the single most common form of spinal deformity seen in orthopedic practice. Our knowledge about the epidemiology, etiology, natural history, and treatment has recently increased dramatically. The incidence of small curves is rather high (2% of the population), whereas severe curves are much less common (<0.1%), but we cannot always predict which curve will progress. Abnormalities of the neuromuscular system and of calcium metabolism, and certain growth, genetic, and mechanical factors may all play roles in the pathogenesis of the disorder. The physiologic secondary effects of severe scoliosis relate to restrictive lung disease, but most patients do not have a deformity great enough to affect their cardiorespiratory function. The psychological and social effects of scoliosis are significant for patients but difficult to quantitate. For most patients with moderate scoliosis—that is, more than 25 to 30 degrees—treatment with an underarm brace or electrical stimulation is adequate to “control” progression of the curve. Surgical fusion allows actual correction of the curve but is indicated in only a small percentage of patients—usually those with more than 50 degrees of deformity. Images PMID:3279708

  20. Idiopathic Inflammatory Myopathies

    2014-01-01

    The idiopathic inflammatory myopathies (IIM) consist of rare heterogenous autoimmune disorders that present with marked proximal and symmetric muscle weakness, except for distal and asymmetric weakness in inclusion body myositis (IBM). Besides frequent creatine kinase (CK) elevation, the electromyogram confirms the presence of an irritative myopathy. Extramuscular involvement affects a significant number of cases with interstitial lung disease (ILD), cutaneous in dermatomyositis (DM), systemic or joint manifestations and increased risk of malignancy especially in DM. Myositis specific autoantibodies influence phenotype of the IIM. Jo-1 antibodies are frequently associated with ILD and the newly described HMG-CoA reductase antibodies are characteristic of autoimmune necrotizing myopathy (NM). Muscle pathology ranges from inflammatory exudates of variable distribution, to intact muscle fiber invasion, necrosis, phagocytosis and in the case of IBM rimmed vacuoles and protein deposits. Despite many similarities, the IIM are a quite heterogeneous from the histopathological and pathogenetic standpoints in addition to some clinical and treatment-response difference. The field has witnessed significant advances in our understanding of pathophysiology and treatment of these rare disorders. In this review, we focus on DM, polymyositis (PM) and NM and examine current and promising therapies. The reader interested in more details on IBM is referred to the corresponding chapter in this issue. PMID:25037081

    Two brothers, aged 3 and 6 years, respectively, had their pulmonary conditions diagnosed as idiopathic pulmonary hemosiderosis (IPH). Both boys had severe iron-deficiency anemia, chronic cough, hemoptysis, and exertional dyspnea, and one had recurrent epistaxis. The results of light microscopic lung histopathologic studies in both patients showed numerous hemosiderinladen macrophages and chronic interstitial pneumonitis. No specific patterns of immunofluorescence of the alveolar capillary basement membranes were found. The results of electron microscopic examinations showed intact alveolar and capillary basement membranes and no evidence of electron-dense deposits. The lack of clinical or biochemical evidence for renal disease as well as the absence of serum antinuclear and antibasement membrane antibodies excluded associated autoimmune disorders. Evaluation for milk-protein allergy was negative and neither child demonstrated a clinical response to a milk-free diet. Sequential pulmonary function studies performed over four years showed episodes of acute obstructive airway disease that correlated with pulmonary hemorrhage and mild persistent restrictive lung disease. The results of this family study suggested that some cases of IPH may have a genetic basis.

    In a 39-year-old patient with chronic progressive idiopathic pulmonary fibrosis, the genetic aspects, course and therapeutic possibilities of the disease are discussed. In February, 1987, the English-born patient, Anthony V., attended for initial examination on account of progressive dyspnoea, on which occasion radiology and pulmonary function analysis revealed advanced pulmonary fibrosis. The patient's family history revealed a familial genesis, since both his father (?) and his sister had died of this disease. A comparative of the patient's chest films with original chest films of his sister revealed almost identical findings. Within the previous twelve months, follow-up examinations done on A.V. revealed an increase in the restrictive component (reduction of vital capacity from 2,400 ml to 1,500 ml), development of partial respiratory failure at rest, and global respiratory failure in response to mild ergometric exercise despite intermittent high-dose steroid administrations superimposed on long-term, low-dose steroid therapy. The unfavourable evolution observed over the past 12 months is underscored by an increase in mean pulmonary arterial pressure from 18 mmHg initially to a present 34 mmHg at rest, and 46 mmHg under submaximal ergometric loading. The only option still left to the patient is the possibility of a lung transplantation, which - probably initially unilateral - is scheduled to be carried out in the near future at the Chest Surgery Department of the Medical University at Hannover.

    2004-07-01

    Idiopathic fascicular ventricular tachycardia is an important cardiac arrhythmia with specific electrocardiographic features and therapeutic options. It is characterized by relatively narrow QRS complex and right bundle branch block pattern. The QRS axis depends on which fascicle is involved in the re-entry. Left axis deviation is noted with left posterior fascicular tachycardia and right axis deviation with left anterior fascicular tachycardia. A left septal fascicular tachycardia with normal axis has also been described. Fascicular tachycardia is usually seen in individuals without structural heart disease. Response to verapamil is an important feature of fascicular tachycardia. Rare instances of termination with intravenous adenosine have also been noted. A presystolic or diastolic potential preceding the QRS, presumed to originate from the Purkinje fibers can be recorded during sinus rhythm and ventricular tachycardia in many patients with fascicular tachycardia. This potential (P potential) has been used as a guide to catheter ablation. Prompt recognition of fascicular tachycardia especially in the emergency department is very important. It is one of the eminently ablatable ventricular tachycardias. Primary ablation has been reported to have a higher success, lesser procedure time and fluoroscopy time.

    Juvenile idiopathic arthritis is the most common rheumatic disease in childhood. It is a chronic inflammatory disease associated with arthritis of unknown etiology that begins before the age of 16 and persists for longer than 6 weeks. In this report, the case of a child who suffered recurrent alternative hip arthritis with bilateral hip arthritis is examined, in which he was finally diagnosed as suffering from Juvenile idiopathic arthritis. A 14-year-old boy of Taiwanese origin presented with a normal birth and developmental history. At the age of 10, right-side hip joint pain was experienced, which later migrated to the left side. On further inspection, synovium hypertrophy, cartilage erosion and hip turbid fluid accumulation were found and aseptic arthritis was presumed to be the primary cause. However, after re-examining both his clinical history and presentation, Juvenile idiopathic arthritis was the final diagnosis. Any child presenting with repeat joint swelling are at risk of Juvenile idiopathic arthritis. This is still to be the case if symptoms recede or heal and no initial diagnosis is made. Therefore, a better understanding of the risk of recurrent arthritis is needed. It cannot be emphasized strongly enough that Juvenile idiopathic arthritis should be suspected at all times when a child suffers from recurrent aseptic arthritis of the hip joint.

    An experience with 216 bilateral hernias in female patients is reviewed. The condition is rare, occurring only once in every 250 patients admitted for a hernia repair. Bilateral primary indirect inguinal hernias were the most frequent type. Bilateral primary femoral hernias were quite rare while bilateral primary direct inguinal hernias were even more uncommon. Other rare bilateral combinations are briefly described. The incidence in children is given. Etiological factors are discussed, emphasizing the strong posterior wall of the inguinal canal in females. Two per cent of patients developed a recurrent hernia; one per cent of hernias recurred. No recurrence following a bilateral primary indirect inguinal hernia repair and no “femoral” recurrence following inguinal repair were recorded. PMID:5348491

    Rationale: Treatment and prognoses of diffuse parenchymal lung diseases (DPLDs) varies by diagnosis. Obtaining a uniform diagnosis among observers is difficult. Objectives: Evaluate diagnostic agreement between academic and community-based physicians for patients with DPLDs, and determine if an interactive approach between clinicians, radiologists, and pathologists improved diagnostic agreement in community and academic centers. Methods: Retrospective review of 39 patients with DPLD. A total of 19 participants reviewed cases at 2 community locations and 1 academic location. Information from the history, physical examination, pulmonary function testing, high-resolution computed tomography, and surgical lung biopsy was collected. Data were presented in the same sequential fashion to three groups of physicians on separate days. Measurements and Main Results: Each observer's diagnosis was coded into one of eight categories. A κ statistic allowing for multiple raters was used to assess agreement in diagnosis. Interactions between clinicians, radiologists, and pathologists improved interobserver agreement at both community and academic sites; however, final agreement was better within academic centers (κ = 0.55–0.71) than within community centers (κ = 0.32–0.44). Clinically significant disagreement was present between academic and community-based physicians (κ = 0.11–0.56). Community physicians were more likely to assign a final diagnosis of idiopathic pulmonary fibrosis compared with academic physicians. Conclusions: Significant disagreement exists in the diagnosis of DPLD between physicians based in communities compared with those in academic centers. Wherever possible, patients should be referred to centers with expertise in diffuse parenchymal lung disorders to help clarify the diagnosis and provide suggestions regarding treatment options.

    2006-03-01

    Idiopathic oligoasthenoteratozoospermia (iOAT) affects approximately 30% of all infertile men. This mini-review discussed recent data in this field. Age, non-inflammatory functional alterations in post-testicular organs, infective agents (Chlamydia trachomatis, herpes virus and adeno-associated viruses), alterations in gamete genome, mitochondrial alterations, environmental pollutants and "subtle" hormonal alterations are all considered possible causes of iOAT. Increase of reactive oxygen species in tubules and in seminal plasma and of apoptosis are reputed to affect sperm concentration, motility and morphology. iOAT is commonly diagnosed by exclusion, nevertheless spectral traces of the main testicular artery may be used as a diagnostic tool for iOAT. The following can be considered therapies for iOAT: 1) tamoxifen citrate (20 mg/d) + testosterone undecanoate (120 mg/d) (pregnancy rate per couple/month [prcm]: 3.8%); 2) folic acid (66 mg/d) + zinc sulfate (5 mg/d); 3) L-carnitine (2 g/d) alone or in combination with acetyl-L-carnitine (1 g/d) (prcm: 2.3%); and 4) both carnitines = one 30 mg cinnoxicam suppository every 4 days (prcm: 8.5%). Alpha-blocking drugs improved sperm concentration but not morphology, motility or pregnancy rate. Tranilast (300 mg/d) increased sperm parameters and pregnancy rates in an initial uncontrolled study. Its efficacy on sperm concentration (but not on sperm motility, morphology or prcm) was confirmed in subsequent published reports. The efficacy of tamoxifen + testosterone undecanoate, tamoxifen alone, and recombinant follicle-stimulating hormone is still a matter for discussion.

    Molecular biomarkers are highly desired in idiopathic pulmonary fibrosis (IPF), where they hold the potential to elucidate underlying disease mechanisms, accelerated drug development, and advance clinical management. Currently, there are no molecular biomarkers in widespread clinical use for IPF, and the search for potential markers remains in its infancy. Proposed core mechanisms in the pathogenesis of IPF for which candidate markers have been offered include alveolar epithelial cell dysfunction, immune dysregulation, and fibrogenesis. Useful markers reflect important pathological pathways, are practically and accurately measured, have undergone extensive validation, and are an improvement upon the current approach for their intended use. The successful development of useful molecular biomarkers is a central challenge for the future of translational research in IPF and will require collaborative efforts among those parties invested in advancing the care of patients with IPF.

    Summary Background To evaluate the safety, etiology and outcomes of patients undergoing bilateral thoracentesis. Methods This is a prospective cohort study of 100 consecutive patients who underwent bilateral thoracenteses in an academic medical center from July 2009 through November 2010. Pleural fluid characteristics and etiologies of the effusions were assessed. Mean differences in levels of fluid characteristics between right and left lungs were tested. Associations between fluid characteristics and occurrence of bilateral malignant effusions were evaluated. The rate of pneumothorax and other complications subsequent to bilateral thoracentesis was determined. Results Exudates were more common than transudates, and most effusions had multiple etiologies, with 83% having two or more etiologies. Bilateral malignant effusions occurred in 19 patients, were the most common single etiology of exudative effusions, and were associated with higher levels of protein and LDH in the pleural fluid. Among 200 thoracenteses performed with a bilateral procedure, seven resulted in pneumothoraces, three of which required chest tube drainage and four were ex vacuo. Conclusions More often than not, there are multiple etiologies that contribute to pleural fluid formation, and of the combinations of etiologies observed congestive heart failure was the most frequent contributor. Exudative effusions are more common than transudates when bilateral effusions are present. Malignancy is a common etiology of exudative effusions. This study suggests that the overall complication rate following bilateral thoracentesis is low and the rate of pneumothorax subsequent to bilateral thoracentesis is comparable to unilateral thoracentesis.

    Onychomadesis is a clinical sign of nail plate separation due to transient or permanent arrest of nail matrix activities. Onychomadesis can be considered as a severe form of Beau's line. This condition usually occurs after trauma, causal diseases, or medications, yet it rarely occurs as an idiopathic condition. We report a case of a 38-year-old Thai female who developed recurrence onychomadesis in several toenails in the absence of predisposing factors or associated conditions. To the best of our knowledge, our patient is the first reported case of idiopathic onychomadesis limited to toenails. PMID:27437152

    Idiopathic dilatation of pulmonary arteries (IDPA) is a rare abnormality of pulmonary arteries, the reported incidence in literature being as low as 0.007% in autopsy samples. With the improvement in diagnostic modalities, antemortem diagnosis of IDPA has been increasingly established by excluding diseases that induce pulmonary arterial enlargement. Here, we present a rare case of idiopathic dilatation of the pulmonary artery admitted with shortness of breath where IDPA was diagnosed as an incidental finding using computed tomography pulmonary angiography and cardiac catheterization.

    2012-09-01

    Lyme disease caused by the spirochete Borrelia burgdorferi is a multisystem disorder characterized by three clinical stages: dermatologic, neurologic, and rheumatologic. The number of known Lyme disease-endemic areas in Canada is increasing as the range of the vector Ixodes scapularis expands into the eastern and central provinces. Southern Ontario, Nova Scotia, southern Manitoba, New Brunswick, and southern Quebec are now considered Lyme disease-endemic regions in Canada. The use of field surveillance to map risk and endemic regions suggests that these geographic areas are growing, in part due to the effects of climate warming. Peripheral facial nerve palsy is the most common neurologic abnormality in the second stage of Lyme borreliosis, with up to 25% of Bell palsy (idiopathic peripheral facial nerve palsy) occurring due to Lyme disease. Here we present a case of occult bilateral facial nerve palsy due to Lyme disease initially diagnosed as Bell palsy. In Lyme disease-endemic regions of Canada, patients presenting with unilateral or bilateral peripheral facial nerve palsy should be evaluated for Lyme disease with serologic testing to avoid misdiagnosis. Serologic testing should not delay initiation of appropriate treatment for presumed Bell palsy.

    2010-06-01

    Cochlear implant surgery became the standard of care in hearing rehabilitation of patients with severe to profound sensorineural hearing loss. This procedure may alter the lives of children and adults enabling them to integrate with the hearing population. In the past, implantation was performed only in one ear, despite the fact that binaural hearing is superior to unilateral, especially in noisy conditions. Cochlear implantation may be performed sequentially or simultaneously. The "sensitive period" of time between hearing loss and implantation and between the two implantations, when performed sequentially, significantly influences the results. Shorter time spans between implantations improve the hearing results after implantation. Hearing success after implantation is highly dependent on the rehabilitation process which includes mapping, implant adjustments and hearing training. Bilateral cochlear implantation in children is recommended as the proposed procedure in spite of the additional financial burden.

    Adolescent idiopathic scoliosis (AIS) is a three-dimensional deformity of the spine . While AIS can progress during growth and cause a surface deformity, it is usually not symptomatic. However, in adulthood, if the final spinal curvature surpasses a certain critical threshold, the risk of health problems and curve progression is increased. The use of scoliosis-specific exercises (SSE) to reduce progression of AIS and postpone or avoid other more invasive treatments is controversial. To evaluate the efficacy of SSE in adolescent patients with AIS. The following databases (up to 30 March 2011) were searched with no language limitations: CENTRAL (The Cochrane Library 2011, issue 2), MEDLINE (from January 1966), EMBASE (from January 1980), CINHAL (from January 1982), SportDiscus (from January 1975), PsycInfo (from January 1887), PEDro (from January 1929). We screened reference lists of articles and also conducted an extensive handsearch of grey literature. Randomised controlled trials and prospective cohort studies with a control group comparing exercises with no treatment, other treatment, surgery, and different types of exercises. Two review authors independently selected studies, assessed risk of bias and extracted data. Two studies (154 participants) were included. There is low quality evidence from one randomised controlled study that exercises as an adjunctive to other conservative treatments increase the efficacy of these treatments (thoracic curve reduced: mean difference (MD) 9.00, (95% confidence interval (CI) 5.47 to 12.53); lumbar curve reduced:MD 8.00, (95% CI 5.08 to 10.92)). There is very low quality evidence from a prospective controlled cohort study that scoliosis-specific exercises structured within an exercise programme can reduce brace prescription (risk ratio (RR) 0.24, (95% CI 0.06 to1.04) as compared to usual physiotherapy (many different kinds of general exercises according to the preferences of the single therapists within different facilities

    A macular hole is an anatomic opening in the retina that develops at the fovea. Macular holes can be seen in highly myopic eyes or following ocular trauma, but the great majority are idiopathic. Pars plana vitrectomy was introduced to treat full-thickness macular holes, which if left untreated have a poor prognosis since spontaneous closure and visual recovery are rare.Vitrectomy is a surgical technique involving the removal of the vitreous body that fills the eye. The surgeon inserts thin cannulas into the eyes through scleral incisions to relieve traction exerted by the vitreous or epiretinal membranes to the central retina and to induce glial tissue to bridge and close the hole. The primary objective of this review was to examine the effects of vitrectomy for idiopathic macular hole on visual acuity. A secondary objective was to investigate anatomic effects on hole closure and other dimensions of visual function, as well as to report on adverse effects recorded in included studies. We searched the Cochrane Eyes and Vision Group Trials Register (4 March 2015), the Cochrane Central Register of Controlled Trials (CENTRAL; 2015, Issue 2), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to March 2015), EMBASE (January 1980 to March 2015), Latin American and Caribbean Health Sciences Literature Database (LILACS) (January 1982 to March 2015), the Web of Science Conference Proceedings Citation Index-Science (CPCI-S) (January 1980 to March 2015), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov) and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en).

Examination showed best-corrected visual acuity of hand motion in the right and 20/400 in the left eye with intraocular pressures (IOP) of 48 mm Hg in the right and 40 mm Hg in the left eye on maximal medical therapy. She had bilateral neovascularization of the iris and angle with synechial angle closure, surgical aniridia, central retinal vein occlusion, and end-stage glaucomatous optic neuropathy. She was diagnosed with neovascular glaucoma in both eyes, associated with cosmetic iris implants. intervention procedures: Humphrey 24-2 visual field testing, optic nerve coherence tomography, and fundus imaging were performed. After bilateral intravitreal bevacizumab and panretinal photocoagulation, Ahmed glaucoma drainage devices were implanted in both eyes. main outcome measures: IOP, anterior chamber inflammation, neovascularization. Despite aggressive treatment, severe permanent bilateral vision loss ensued. We strongly advise against the use of anterior chamber iris implants for cosmetic indications. Close monitoring of implanted individuals is necessary. Explantation should be considered at the earliest sign of adverse reaction. Copyright © 2011 Elsevier Inc. All rights reserved.

    Abstract Idiopathic CD4 T lymphocytopenia (ICL) is a rare and severe condition with limited available data. We conducted a French multicenter study to analyze the clinical and immunologic characteristics of a cohort of patients with ICL according to the Centers for Disease Control criteria. We recruited 40 patients (24 female) of mean age 44.2 ± 12.2 (19–70) years. Patients underwent T-lymphocyte phenotyping and lymphoproliferation assay at diagnosis, and experiments related to thymic function and interferon (IFN)-γ release by natural killer (NK) cell were performed. Mean follow-up was 6.9 ± 6.7 (0.14–24.3) years. Infectious, autoimmune, and neoplastic events were recorded, as were outcomes of interleukin 2 therapy. In all, 25 patients had opportunistic infections (12 with human papillomavirus infection), 14 had autoimmune symptoms, 5 had malignancies, and 8 had mild or no symptoms. At the time of diagnosis, the mean cell counts were as follows: mean CD4 cell count: 127/mm3 (range, 4–294); mean CD8: 236/mm3 (range, 1–1293); mean CD19: 113/mm3 (range, 3–547); and mean NK cell count: 122/mm3 (range, 5–416). Most patients had deficiency in CD8, CD19, and/or NK cells. Cytotoxic function of NK cells was normal, and patients with infections had a significantly lower NK cell count than those without (p = 0.01). Patients with autoimmune manifestations had increased CD8 T-cell count. Proliferation of thymic precursors, as assessed by T-cell rearrangement excision circles, was increased. Six patients died (15%). CD4 T-cell count <150/mm3 and NK cell count <100/mm3 were predictors of death. In conclusion, ICL is a heterogeneous disorder often associated with deficiencies in CD8, CD19, and/or NK cells. Long-term prognosis may be related to initial CD4 and NK cell deficiency.

    Defining the precise nosological limits of narcolepsy and idiopathic hypersomnia is an ongoing process dating back to the first description of the two conditions. The most recent step forward has been done within the preparation of the second edition of the "International classification of sleep disorders" published in June 2005. Appointed by Dr Emmanuel Mignot, the Task Force on "Hypersomnias of central origin, not due to a circadian rhythm sleep disorder, sleep related breathing disorder, or other causes of disturbed nocturnal sleep" thoroughly revisited the nosology of narcolepsy and of idiopathic hypersomnia. Narcolepsy is now distinguished into three different entities, narcolepsy with cataplexy, narcolepsy without cataplexy and narcolepsy due to medical condition, and idiopathic hypersomnia into two entities, idiopathic hypersomnia with long sleep time and idiopathic hypersomnia without long sleep time. Nevertheless there are still a number of pending issues. What are the limits of narcolepsy without cataplexy? Is there a continuum in the pathophysiology of narcolepsy with and without cataplexy? Should sporadic and familial forms of narcolepsy with cataplexy appear as subgroups in the classification? Are idiopathic hypersomnia with long sleep time and idiopathic hypersomnia without long sleep time, two forms of the same condition or two different conditions? Is there a pathophysiological relationship between narcolepsy without cataplexy and idiopathic hypersomnia without long sleep time?

    Idiopathic facial palsy is the most common cause of facial nerve palsy in children. Controversy exists regarding treatment options. The objectives of this study were to review the epidemiological and clinical characteristics as well as the outcome of idiopathic facial palsy in children to suggest appropriate treatment. A retrospective study was conducted on children with a diagnosis of idiopathic facial palsy from 2007 to 2012. A total of 37 cases (13 males, 24 females) with a mean age of 13.9 years were included in this analysis. The mean duration between onset of Bell's palsy and consultation was 3 days. Of these patients, 78.3% had moderately severe (grade IV) or severe paralysis (grade V on the House and Brackmann grading). Twenty-seven patients were treated in an outpatient context, three patients were hospitalized, and seven patients were treated as outpatients and subsequently hospitalized. All patients received corticosteroids. Eight of them also received antiviral treatment. The complete recovery rate was 94.6% (35/37). The duration of complete recovery was 7.4 weeks. Children with idiopathic facial palsy have a very good prognosis. The complete recovery rate exceeds 90%. However, controversy exists regarding treatment options. High-quality studies have been conducted on adult populations. Medical treatment based on corticosteroids alone or combined with antiviral treatment is certainly effective in improving facial function outcomes in adults. In children, the recommendation for prescription of steroids and antiviral drugs based on adult treatment appears to be justified. Randomized controlled trials in the pediatric population are recommended to define a strategy for management of idiopathic facial paralysis. Copyright © 2015 Elsevier Masson SAS.

  2. Traumatic bilateral renal infarction.

    PubMed

    Peterson, N E

    1989-02-01

    Published examples of unilateral and bilateral renal artery thrombosis attest to their usual subjection to nephrectomy at diagnosis or soon thereafter, eliminating the opportunity for spontaneous improvement which would enlighten the issue of how often late recovery may occur, and under what circumstances. Seven cases of renal artery thrombosis and five patients with renal artery embolization extracted from the literature have included documentation of patchy histologic viability within otherwise total infarction. Conversely, 47 reports of renal artery thrombosis culminating in nephrectomy or examined post mortem include no reference to any of these histologic features. Presumptions are speculative regarding whether these features were absent, overlooked, or unexamined. Their incidence cannot be estimated--only the possibility of recoverable renal function in an unknown number of involved patients. It may be presumed that the majority of kidneys exposed to sustained arterial interruption will undergo irreversible infarction, with an undefined small subgroup later developing renal hypertension. An unknown number, however, may fortuitously possess arterial collateralization competent to support sufficient numbers of viable nephrons to sustain adequate renal function. It is further speculated that shared pathophysiologic features establish the opportunity for misdiagnosis of renal cortical necrosis, which carries a documented potential for spontaneous recovery. Impulsive bilateral nephrectomy may therefore be unjustified, particularly in consideration of the minimal potential hazards of nonremoval. In the event of convalescent problems of renal origin, delayed nephrectomy remains an option. The requirement for interval hemodialysis is further influenced by the advantages accruing from retention of the native kidneys relative to calcium metabolism and blood product replacement. A final consideration relates to the advisability of secondary revascularization of

    its position in the window as well as the pixel value for the central pixel of the window. The absolute difference between these two pixel values is calculated and used as an address in a lookup table. Each processing element has a lookup table, unique for its position in the window, containing the weight coefficients for the Gaussian function for that position. The pixel value is multiplied by the weight, and the outputs of the processing element are the weight and pixel-value weight product. The products and weights are fed to the adder tree. The sum of the products and the sum of the weights are fed to the divider, which computes the sum of products the sum of weights. The output of the divider is denoted the bilateral smoothed image. The smoothing function is a simple weighted average computed over a 3 3 subwindow centered in the 9 9 window. After smoothing, the image is delayed by an additional amount of time needed to match the processing time for computing the bilateral smoothed image. The bilateral smoothed image is then subtracted from the 3 3 smoothed image to produce the final output. The prototype filter as implemented in a commercially available FPGA processes one pixel per clock cycle. Operation at a clock speed of 66 MHz has been demonstrated, and results of a static timing analysis have been interpreted as suggesting that the clock speed could be increased to as much as 100 MHz.

  4. Acute otitis media associated bilateral sudden hearing loss: case report and literature review.

    Sudden sensorineural hearing loss is a rare otological condition with potential for dire outcomes including permanent hearing loss. Although the majority of cases are deemed idiopathic, bilateral sudden sensorineural hearing loss represents a rare subset typically related to systemic conditions, with higher morbidity and mortality. A controversial association with acute otitis media has been reported, with few bilateral cases published in the literature. A very rare case of bilateral sudden sensorineural hearing loss associated with acute otitis media is described, with a review of the literature. The limited evidence available suggests that acute otitis media with tinnitus and/or bacterial pathology may have an increased risk of sudden sensorineural hearing loss, which is consistent with the case described. Although there is no sufficiently powered published evidence to provide definitive treatment guidelines, the literature reviewed suggests that early myringotomy and antibiotics may greatly improve treatment outcomes.

    Purpose To evaluate the safety and preliminary efficacy of intravitreal ranibizumab for non-neovascular idiopathic macular telangiectasia, type 2 (IMT2). Methods Single-center, open-label phase II clinical trial enrolling 5 participants with bilateral non-neovascular IMT2. Intravitreal ranibizumab (0.5mg) was administered every 4 weeks in the study eye for 12 months with the contralateral eye observed. Outcome measures included changes in: best corrected visual acuity (BCVA), area of late-phase leakage on fluorescein angiography (FA), and retinal thickness on optical coherence tomography (OCT). Results The study treatment was well-tolerated and associated with few adverse events. Change in BCVA at 12 months was not significantly different between treated study eyes (0.0±7.5 letters) and control fellow eyes (+2.2±1.9 letters). However, decreases in the area of late-phase FA leakage (−33±20% for study eyes, +1±8% for fellow eyes) and in OCT central subfield retinal thickness (−11.7±7.0% for study eyes and −2.9±3.5% for fellow eyes) were greater in study eyes compared to fellow eyes. Conclusions Despite significant anatomical responses to treatment, functional improvement in visual acuity was not detected. Intravitreal ranibizumab administered monthly over a time course of 12 months is unlikely to provide a general and significant benefit to patients with non-neovascular IMT2. PMID:22266930

    The Val66Met (G196A; rs6265) single nucleotide polymorphism of brain-derived neurotrophic factor (BDNF) affects morphology and neuronal activity, and is expected to be associated with central nervous system disorders. However, it remains controversial whether Val66Met polymorphism is a risk factor for idiopathic dystonia. We aimed to clarify the impact of BDNF polymorphism on idiopathic dystonia. A literature search of PubMed was carried out. A random-effects model was employed for the meta-analysis. A pooled odds ratio (OR) was calculated along with 95% confidence intervals (CI) to reflect the risk of idiopathic dystonia in each genotype (GG, AG, AA) or minor allele. The proportion of variation due to heterogeneity was computed and expressed as I(2). Five case-control studies, comprising a total sample size of 1804 subjects (784 idiopathic dystonia patients, 1020 normal controls), were included in this meta-analysis. AA genotype was significantly more frequent in patients with idiopathic dystonia (OR=1.47, 95% CI 1.09-1.99, p=0.01, four studies, n=1716). This finding was derived from homogeneous studies (p=0.97, I(2)=0%). Our meta-analysis has revealed a significant overall effect of the AA genotype on the development of idiopathic dystonia.

    We report a case of a 35 year-old woman with idiopathic thrombocytopenic purpura (ITP) who, under treatment with immunosuppressive drugs, developed bilateral interstitial pulmonary disease. Previously she had been splenectomized and treated with corticosteroids and cyclosporin. During the clinical course, the patient developed alterations of the hepatogram and presented a positive serology for Epstein-Barr virus. The lung biopsy showed the histologic pattern of obliterative bronchiolitis, interstitial inflammatory infiltration and intraalveolar pneumonia (BOOP). We could not find in the literature a previous report in which ITP was associated with BOOP. Of interest was the spontaneous remission of the pulmonary disease after suppression of cyclosporin and positive serology for Epstein-Barr virus.

    We report an autopsy case of sudden death in a 36-year-old craftsman with idiopathic scoliosis. The doctor identified his scoliosis at the age of thirteen, and he was under medical care for three years until he stopped consulting the doctor. He collapsed while walking at the station and was sent to an emergency room in cardiopulmonary arrest state, where he was declared dead in spite of more than an hour of CPR. Numbers of petechiae were seen on the bilateral palpebral conjunctivae and the lips were cyanotic. There were no particular injuries except for small abrasions observed on the face. The back showed right rib hump owing to midthoracic scoliosis (with 73 degrees of Cobb's angle) and right hemithorax was deformed showing an appearance of pectus excavatum in the front. The volume of the right thoracic cavity was significantly decreased. In the right lung, there was extensive stromal fibrosis, leaving almost no normal alveolar structures, and medial hypertrophy of pulmonary arteriolar walls. Hypertrophy of the right heart ventricle due to these pulmonary changes and the congestion of other organs suggested that the cause of death in this case was cor pulmonale due to pulmonary hypertension. This was a rare case of fatal outcome of advanced idiopathic scoliosis without medical care in spite of early detection through mass screening.

  10. Pleural effusions in acute idiopathic pericarditis and postcardiac injury syndrome.

    PubMed

    Porcel, José M

    2017-07-01

    Pleural effusions are frequent in the context of acute idiopathic pericarditis and following pericardiotomy, but they have seldom been characterized. This review summarizes their most relevant clinical features. In acute idiopathic pericarditis, pleural effusions tend to be left-sided and, if bilateral, they are usually larger on the left. Less than 5% are unilateral right-sided. About 90% of the effusions occupy less than one-third of the hemithorax, and 99% meet Light's exudative criteria with a predominance of lymphocytes in three fourths of the cases. Although postcardiac injury syndrome (PCIS)-related effusions share similar characteristics, they present some differential features: more than 15% are unilateral on the right (except for Dressler syndrome), one-fourth opacify half or more of the hemithorax, and nearly two thirds are bloody. The combination of nonsteroidal anti-inflammatory drugs and colchicine, along with therapeutic thoracenteses for moderate-to-large effusions, is the mainstay treatment approach. The postoperative use of colchicine is also a reasonable option for preventing PCIS in patients who have undergone cardiac surgery. Pleural effusions because of pericardial diseases remain a clinical diagnosis. If unilateral right-sided, massive, or transudative effusions are seen, an alternative diagnosis to acute pericarditis should be considered.

    Abstract A 33-year-old female patient with advanced idiopathic pulmonary artery hypertension underwent bilateral lung transplantation. The postsurgical course was complicated by prolonged mechanical ventilation and acute hypoxemia with recurrent episodes of pulmonary edema. An echocardiogram revealed improved right-sided pressures along with a dilated left atrium, a structurally normal mitral valve, and a new posterior-oriented severe mitral regurgitation. The patient's condition improved after treatment with arterial vasodilators and diuretics, and she has remained in World Health Organization functional class I after almost 36 months of follow-up. We hypothesize that cardiac ventricle remodeling and a geometric change in mitral valve apparatus after transplantation led to the hemodynamic changes and recurrent pulmonary edema seen in our patient. Our case is, to our knowledge, the second report of severe valvular regurgitation in a structurally normal mitral valve apparatus in the postoperative period and the first of a patient to be treated without valve replacement.

  12. Nonsurgical management of idiopathic clubfoot.

    PubMed

    Noonan, Kenneth J; Richards, B Stephens

    2003-01-01

    Because nonsurgical management was thought not to yield adequate correction and a durable result, most children with idiopathic clubfoot have undergone surgery with extensive posteromedial and lateral release. However, surgical management caused residual deformity, stiffness, and pain in some children; thus, the favorable long-term results with the Ponseti and French methods of nonsurgical management have garnered interest. The Ponseti method consists of manipulation and casting of idiopathic clubfeet; the French method consists of physiotherapy, taping, and continuous passive motion. Careful evaluation of the techniques and results of these two approaches may increase their use and decrease or minimize the use of surgical management and thus the associated morbidity resulting from extensile releases.

    Idiopathic interstitial pneumonias comprise 8 clinicopathological entities, most of them with a chronic course and various prognosis. Idiopathic pulmonary fibrosis is the most frequent and most severe of these. Computed tomography has an important role for its diagnosis. It can identify the corresponding pathological pattern of usual interstitial pneumonia in about 50 percent of cases. It can suggest differential diagnosis in other cases, most frequently fibrosing nonspecific interstitial pneumonia and chronic hypersensitivity pneumonitis. Imaging features should be integrated to clinical and available pathologic data during multidisciplinary team meetings involving physicians with a good knowledge of interstitial diseases. Some cases may be unclassifiable, but these could later be reclassified as new data may occur or imaging features may change. Surgical lung biopsy is being less frequently performed and an emerging less invasive technique, lung cryobiopsy, is under evaluation. Pleuroparenchymal fibroelastosis is a distinct entity only recently described, with uncertain prevalence and prognosis that seems being quite often associated to another pattern of interstitial pneumonia.

  14. Gait in 5-year-old children with idiopathic clubfoot: A cohort study of 59 children, focusing on foot involvement and the contralateral foot.

    PubMed

    Background and purpose - Idiopathic clubfoot can be bilateral or unilateral; however, most studies of gait have assessed clubfoot cases as one uniform group. The contralateral foot in children with unilateral clubfoot has shown deviations in pedobarographic measurements, but it is seldom included in studies of gait. We evaluated gait in children with idiopathic clubfoot, concentrating on foot involvement. Patients and methods - Three-dimensional gait analyses of 59 children, mean age 5.4 years, with bilateral (n = 30) or unilateral (n = 29) idiopathic clubfoot were stratified into groups of bilateral, unilateral, or contralateral feet. Age-matched controls (n = 28) were evaluated for comparison. Gait assessment included: (1) discrete kinematic and kinetic parameters, and (2) gait deviation index for kinematics (GDI) and kinetics (GDI-k). Results - No differences in gait were found between bilateral and unilateral idiopathic clubfoot, but both groups deviated when compared to controls. Compared to control feet, contralateral feet showed no deviations in discrete gait parameters, but discrepancies were evident in relation to unilateral clubfoot, causing gait asymmetries in children with unilateral involvement. However, all groups deviated significantly from control feet according to GDI and GDI-k. Interpretation - Bilateral and unilateral idiopathic clubfoot cases show the same persistent deviations in gait, mainly regarding reduced plantarflexion. Nevertheless, knowledge of foot involvement is important as children with unilateral clubfoot show gait asymmetries, which might give an impression of poorer deviations. The results of GDI/GDI-k indicate global gait adaptations of the contralateral foot, so the foot should preferably not be used as a reference for gait.

    The objective is the description and summary of the current state of idiopathic scoliosis treatment with physical therapy based on new scientific knowledge and concluded from more than 15 years of experience as a leading physician in two well-known clinics specializing in the conservative treatment of scoliosis. Based on current scientific publications on physical therapy in scoliosis treatment and resulting from the considerable personal experience gained working with conservative treatment and consulting scoliosis patients (as inpatients and outpatients), the current methods of physical therapy have been compared and evaluated. Physical therapy according to Schroth and Vojta therapy are at present the most common and effective methods in the physical treatment of idiopathic scoliosis. These methods can be applied during inpatient or outpatient treatment or intensified in the practice of specialized therapists. As there are only a few scientific studies on this subject, the author's findings are based mainly on his own experiences of the conservative treatment of idiopathic scoliosis. Athough these experiences are the results of over 15 years of working in the field of therapy, and the Schroth method in combination with corrective bracing presents highly promising results, it would nevertheless be desirable to conduct detailed scientific studies to verify the effectiveness of conservative treatment.

    2009-10-01

    The goal of this review is to examine the most recent literature exploring the indications, outcomes, and long-term benefit of bilateral cochlear implantation in children and adults. The indications for cochlear implantation have expanded, as many unilaterally implanted individuals are able to achieve open-set word recognition. Despite the benefits seen in unilateral implantation, many individuals have difficulty perceiving speech in noisy environments. Bilateral cochlear implantation has made great strides in providing individuals access to sound information from both ears, allowing improved speech perception in quiet and in noise, as well as sound localization. Recently, the House Cochlear Implant study group released a position statement in which the group strongly endorsed bilateral cochlear implantation. Improved speech perception in quiet has also been demonstrated by many groups with bilateral implantation. Improved sound localization abilities have been shown to be dependent on interaural level differences. The binaural benefits of head shadow and summation have been long shown in bilaterally implanted individuals. Recently, a growth in squelch has been seen in these individuals likely as a result of increased experience with both implants. This may indicate neural integration of the inputs over time. The literature supports the binaural benefit of bilateral cochlear implantation with demonstrated improved speech perception outcomes in quiet and in noise, sound localization data, and subjective benefits.

    Idiopathic scoliosis causes respiratory muscles weakness and reduced exercise capacity. However, the mechanism of these symptoms is still unknown. The main objective of this study was to determine the intensity of respiratory muscle activity and exercise capacity in patients with idiopathic scoliosis in comparison with healthy people. In this study, 20 female patients with adult idiopathic scoliosis (10 mild and 10 moderate) as well as 10 healthy matched individuals with characteristics of the patients were selected. The subjects were fatigued through a maximal incremental cycle ergometry protocol. Meanwhile, the electromyography values of the external intercostal muscles and diaphragm were recorded bilaterally, and fatigue duration was determined. The root mean square of concave external intercostal muscles and concave diaphragm in patients with idiopathic scoliosis was significantly reduced during the fatiguing exercise protocol compared with healthy individuals. The median frequencies of the two sides differed significantly and were lower in patients with moderate scoliosis than healthy subjects. Fatigue duration (minutes) also was lower in patients with moderate scoliosis than healthy subjects. Scoliosis causes respiratory muscle weakness and reduced fatigue duration in response to mild physical activity compared with healthy subjects and these dysfunctions appear to be related to the severity of scoliosis curvature (moderate > mild).

  2. French consensus. Idiopathic hypersomnia: Investigations and follow-up.

    PubMed

    Leu-Semenescu, S; Quera-Salva, M-A; Dauvilliers, Y

    Idiopathic hypersomnia is a rare, central hypersomnia, recently identified and to date of unknown physiopathology. It is characterised by a more or less permanent, excessive daytime sleepiness, associated with long and unrefreshing naps. Night-time sleep is of good quality, excessive in quantity, associated with sleep inertia in the subtype previously described as "with long sleep time". Diagnosis of idiopathic hypersomnia is complex due to the absence of a quantifiable biomarker, the heterogeneous symptoms, which overlap with the clinical picture of type 2 narcolepsy, and its variable evolution over time. Detailed evaluation enables other frequent causes of somnolence, such as depression or sleep deprivation, to be eliminated. Polysomnography and multiple sleep latency tests (MSLT) are essential to rule out other sleep pathologies and to objectify excessive daytime sleepiness. Sometimes the MSLT do not show excessive sleepiness, hence a continued sleep recording of at least 24hours is necessary to show prolonged sleep (>11h/24h). In this article, we propose recommendations for the work-up to be carried out during diagnosis and follow-up for patients suffering from idiopathic hypersomnia.

  3. EphA4-Mediated Ipsilateral Corticospinal Tract Misprojections Are Necessary for Bilateral Voluntary Movements But Not Bilateral Stereotypic Locomotion

    PubMed Central

    Serradj, Najet; Paixão, Sónia; Sobocki, Tomasz; Feinberg, Mitchell; Klein, Rüdiger; Kullander, Klas

    2014-01-01

    In this study, we took advantage of the reported role of EphA4 in determining the contralateral spinal projection of the corticospinal tract (CST) to investigate the effects of ipsilateral misprojections on voluntary movements and stereotypic locomotion. Null EphA4 mutations produce robust ipsilateral CST misprojections, resulting in bilateral corticospinal tracts. We hypothesize that a unilateral voluntary limb movement, not a stereotypic locomotor movement, will become a bilateral movement in EphA4 knock-out mice with a bilateral CST. However, in EphA4 full knock-outs, spinal interneurons also develop bilateral misprojections. Aberrant bilateral spinal circuits could thus transform unilateral corticospinal control signals into bilateral movements. We therefore studied mice with conditional forebrain deletion of the EphA4 gene under control by Emx1, a gene expressed in the forebrain that affects the developing CST but spares brainstem motor pathways and spinal motor circuits. We examined two conditional knock-outs targeting forebrain EphA4 during performance of stereotypic locomotion and voluntary movement: adaptive locomotion over obstacles and exploratory reaching. We found that the conditional knock-outs used alternate stepping, not hopping, during overground locomotion, suggesting normal central pattern generator function and supporting our hypothesis of minimal CST involvement in the moment-to-moment control of stereotypic locomotion. In contrast, the conditional knock-outs showed bilateral voluntary movements under conditions when single limb movements are normally produced and, as a basis for this aberrant control, developed a bilateral motor map in motor cortex that is driven by the aberrant ipsilateral CST misprojections. Therefore, a specific change in CST connectivity is associated with and explains a change in voluntary movement. PMID:24719100

    To report a 65-year-old male patient with bilateral phakic cystoid macular edema secondary to idiopathic macular telangiectasia type 1, with robust response to topical steroidal and non-steroidal agents. Retrospective interventional case report. Chart review. Snellen visual acuity was 20/40 bilaterally. Color fundus photographs showing golden crystalline deposits temporal to the fovea; fluorescein angiography demonstrating telangiectasias with late leakage; and spectral-domain optical coherence tomography revealing intraretinal and subretinal fluid demonstrated findings consistent with idiopathic macular telangiectasia type 1 with bilateral cystoid macular edema. The patient was treated with steroidal and non-steroidal anti-inflammatory drops with complete resolution of edema within two months and improved visual acuity. Over the next two years, edema recurred whenever the drops were stopped and disappeared with reinstitution of topical therapy. Topical steroidal and non-steroidal anti-inflammatory agents may lead to long-term resolution of cystoid macular edema secondary to idiopathic macular telangiectasia type 1.

    This case describes the technique of using dual Novalungs (a pumpless extracorporeal system) to bridge a patient with idiopathic pulmonary hypertension to bilateral lung transplantation. A 41-year old lady with idiopathic pulmonary hypertension (with a possible veno-occlusive element) presented with symptoms of end-stage heart and lung failure. This was refractory to medical management with iloprost, sildenafil and bosentan. The patient was placed on the urgent waiting list for lung transplantation and central pulmonary artery to left atrial Novalung insertion was performed. Local anaesthetic was given before performing peripheral cardiopulmonary bypass due to the high risk of cardiac arrest. Two days later, donor organs became available and the patient was taken for double-lung transplantation. The pulmonary artery cannula was removed leaving a large defect. This was then closed using a bovine pericardial patch. Due to the damaged right superior pulmonary vein from Novalung cannulation, cardioplegia was given to facilitate an open atrial anastomosis. After 13 days in the intensive therapy unit, she was transferred to the ward. There were no further complications and she has been discharged home.

    The term idiopathic focal epilepsies of childhood (IFE) is not formally recognised by the ILAE in its 2010 revision (Berg et al., 2010), nor are its members and boundaries precisely delineated. The IFEs are amongst the most commonly encountered epilepsy syndromes affecting children. They are fascinating disorders that hold many "treats" for both clinicians and researchers. For example, the IFEs pose many of the most interesting questions central to epileptology: how are functional brain networks involved in the manifestation of epilepsy? What are the shared mechanisms of comorbidity between epilepsy and neurodevelopmental disorders? How do focal EEG discharges impact cognitive functioning? What explains the age-related expression of these syndromes? Why are EEG discharges and seizures so tightly locked to slow-wave sleep? In the last few decades, the clinical symptomatology and the respective courses of many IFEs have been described, although they are still not widely appreciated beyond the specialist community. Most neurologists would recognise the core syndromes of IFE to comprise: benign epilepsy of childhood with centro-temporal spikes or Rolandic epilepsy (BECTS/RE); Panayiotopoulos syndrome; and the idiopathic occipital epilepsies (Gastaut and photosensitive types). The Landau-Kleffner syndrome and the related (idiopathic) epilepsy with continuous spikes and waves in sleep (CSWS or ESES) are also often included, both as a consequence of the shared morphology of the interictal discharges and their potential evolution from core syndromes, for example, CSWS from BECTS. Atypical benign focal epilepsy of childhood also has shared electro-clinical features warranting inclusion. In addition, a number of less well-defined syndromes of IFE have been proposed, including benign childhood seizures with affective symptoms, benign childhood epilepsy with parietal spikes, benign childhood seizures with frontal or midline spikes, and benign focal seizures of adolescence.

    2009-01-01

    This paper summarises findings from studies that evaluated the benefits of bimodal fitting (combining a hearing aid and a cochlear implant in opposite ears) or bilateral cochlear implantation, relative to unilateral implantation, for children (Ching et al., 2007). On average, the size of binaural speech intelligibility advantages due to redundancy and head shadow was similar for the two bilateral conditions. An added advantage of bimodal fitting was that the low-frequency cues provided by acoustic hearing complemented the high-frequency cues conveyed by electric hearing in perception of voice and music. Some children with bilateral cochlear implants were able to use spatial separation between speech and noise to improve speech perception in noise. This is possibly a combined effect of the directional microphones in their implant systems and their ability to use spatial cues. The evidence to date supports the provision of hearing in two ears as the standard of care.

    Bilateral patellar tendon rupture is a rare entity, often associated with systemic diseases and patellar tendinopathy. The authors report a rare case of a 34-year-old man with simultaneous bilateral rupture of the patellar tendon caused by minor trauma. The patient is a retired basketball player with no past complaints of chronic knee pain and a history of steroid use. Surgical management consisted in primary end-to-end tendon repair protected temporarily with cerclage wiring, followed by a short immobilization period and intensive rehabilitation program. Five months after surgery, the patient was able to fully participate in sport activities.

    We report a personal series of 28 patients with neurofibromatosis 2 (NF-2), emphasizing the differences from classical NF-1. The hallmark of NF-2 is bilateral acoustic neuromas with initial symptoms usually occurring in the second or third decade. The natural history may lead to bilateral deafness, but hearing loss may also be a complication of surgery. NF-2 is frequently accompanied by additional intracranial tumors (particularly multiple meningiomas). Half of our patients had a spinal space-occupying lesion. NF-2 is inherited as an autosomal dominant trait, and many patients appear to represent new mutations.

    Idiopathic intracranial hypertension is a variety of intracranial hypertension that is extremely rare in men. Obesity and hypogonadism are the most important predictive factors. Etiological hypotheses include increased central venous pressure, and various hormonal and metabolic changes commonly found in obese patients. We described the case of an obese man with prostate cancer who showed a consistent bodyweight increase during treatment with taxanes and prednisone. He was hospitalized because of a severe loss of vision as a consequence of idiopathic intracranial hypertension. A complete symptom remission was obtained after 3 weeks of anti-edema therapies (steroids, acetazolamide). Castration-resistant prostate cancer is a risk factor for idiopathic intracranial hypertension. Long-term androgen deprivation therapy, bodyweight increase, and fluid retention during chronic steroid administration and taxane chemotherapy might favor the disease onset. This severe complication has a good outcome, and should be suspected in the presence of symptoms and signs of intracranial hypertension.

    We investigated the effects of increased inter-hemispheric interaction (IHI) on five creativity dimensions (appropriateness, detail, categorical distinctiveness, fluency, and originality) of the Alternate Uses Task. Two methods were used to indicate degree of IHI. Trait IHI was indicated by individual differences in handedness, mixed-handers showing greater IHI than strong-handers. State IHI was directly manipulated by central (control group) and bilateral viewing conditions of a 30 s eye movement task (EM). Results indicate significantly higher creativity for mixed-handers, as compared to strong-handers, for all five sub-scores separately and linearly combined. Bilateral EM increased originality and categorical distinctiveness (i.e., flexibility) of strong-handers, but had no effect on mixed-handers. Strong-handers in the bilateral EM group were not different from mixed-handers. Additionally, the bilateral EM effect on strong-handers had different durations for originality (up to 7-9 min) and categorical distinctiveness (up to 3 min). The results suggest that greater IHI can facilitate creativity of strong-handers, but that the characteristically higher IHI of mixed-handers was unaffected by the bilateral EM manipulation.

    The interactions between the bilaterally distributed components of the circadin system that controls the locomotor activity rhythm of the cockroach Leucophaea maderae were investigated in a series of surgical lesion experiments. Complete excision of one optic lobe (either right or left) or its surgical isolation from the central nervous system had no effect on the animals' ability to free-run in constant darkness nor was there any indication, as judged by postoperative pi values of any difference between left and right lobe pacemakers. However, these surgical procedures consistently resulted in a significant increase in tau over preoperative value while optic nerve section had no effect on tau. The propostion is developed that the left and right pacemakers in the two optic lobes are mutally coupled and that the compound pacemaker's period is shorter than either of its constituent pacemakers. It was also found that the integrity of either compound eye is sufficient to assure entrainment of both left and right pacemakers.

    Objective To investigate the occurrence ratio, localization, and surgical outcomes of intraretinal cystic spaces in idiopathic epiretinal membranes (ERMs). Methods We retrospectively reviewed the charts of 432 eyes of 398 consecutive patients with idiopathic ERM who underwent vitrectomy and ERM peeling from January 2012 to September 2015. We selected cases with intraretinal cystic space prior to surgery, detected by spectral-domain optical coherence tomography. We then evaluated the effects of ERM peeling on intraretinal cystic spaces, best corrected visual acuity, and central retinal thickness at 6 months after surgery. Results Twenty-four eyes (5.5%) showed intraretinal cystic spaces before surgery, present in the inner retinal layer (the inner group) in 9 eyes, in the outer retinal layer (the outer group) in 6 eyes, and in both the inner and the outer retinal layers (the combined group) in 9 eyes. Additionally, 30 eyes with ERM but without any presence of intraretinal cystic space were selected randomly and classified as the no cyst group. At 6 months after surgery, the disappearance rate of cystic spaces was significantly greater for the outer group than for the inner group (83.3% and 11.1%, respectively, P = 0.011). The mean best corrected visual acuity improved significantly after surgery in the inner group, the outer group, and the no cyst group (P < 0.05 for all three groups) but did not improve in the combined group (P = 0.58). The mean central retinal thickness decreased significantly after surgery in the inner group, the combined group, and the no cyst group (P < 0.05). Conclusions Intraretinal cystic spaces were observed in 5.5% of preoperative idiopathic ERM cases. Following surgery, the cystic spaces in the outer retinal layer disappeared at higher rates than those in the inner retinal layer, suggesting that the pathophysiologies of these cystic spaces are different.

    Electrodermal activity (EDA) was recorded as skin potential responses (SPRs), on the hindpaws of cats during waking and sleep. SPRs recorded on both paws showed an overall parallelism during all stages of vigilance. SPRs on both paws significantly decreased in amplitude and in frequency from wakefulness to sleep. Most SPRs were synchronous but showed bilateral differences larger than 0.1 mV. However, this asymmetry did not show any significant variation as a function of sleep stages. Electrical stimulation of the reticular central tegmental field at levels below the thresholds for behavioral and cortical arousal thresholds evoked SPRs during wakefulness and all stages of sleep. Bilateral differences between evoked SPR amplitudes did not show significant variations as a function of the stages of vigilance. Moreover, the bilateral asymmetry of the evoked SPRs was significantly lower than that of the spontaneous SPRs. These results are discussed in relation to the variations in bilateral EDA recorded in humans during waking and sleep; the influence of central and peripheral factors on EDA laterality is also discussed.

    Bilateral arm training has emerged as an approach that leads to positive outcomes in addressing upper extremity paresis after stroke. However, studies have not demonstrated improvements in all patients using current outcome measures. Furthermore, the rationale for using this type of training has been incompletely explained. The purpose of this article was to first review the theoretical justifications for the use of bilateral arm training by examining motor control and neural mechanisms underlying arm function and neural recovery, and second, to discuss examples of clinical studies using a variety of bilateral training strategies to identify who may benefit most from this approach. We argue that bilateral arm training is a necessary adjunct to unilateral training because bilateral re-training is important and best served through bilateral not unilateral training, and also, that bilateral training may help unilateral skill recovery through alternative putative mechanisms. Our review of the empirical evidence suggests that individuals at all levels of severity can benefit in some manner from bilateral training, but that not all approaches are effective for all severity levels. In addition to requesting more randomized controlled trials and studies of neurophysiological mechanisms we conclude the following: 1) Bilateral training can improve unilateral paretic limb functions of the upper extremity after stroke, however, specific training approaches need to be matched to baseline characteristics of the patients; 2) Given the importance of bilateral activities in daily life, there is a need to recognize, train and assess the important contribution of supportive role functions of the paretic arm used on its own and as part of complementary bilateral functional skills; 3) An assessment of bilateral and unilateral functioning which includes bilateral task analysis, as well as, evaluations of interlimb coordination should be included in all studies that include bilateral

    The objective was to report a case of pseudoxanthoma elasticum associated with type 2A idiopathic juxtafoveolar telangiectasis (T2AIJT) complicated by bilateral subretinal neovascular membranes (SRNVM). The right eye with juxtafoveal SRNVM and the left eye with subfoveal SRNVM underwent laser photocoagulation and photodynamic therapy respectively. The follow-up duration was 48 months. Best corrected visual acuity was 20/32 in both eyes at baseline, and 20/32 in the right eye and 20/200 in the left eye at the end of the follow-up. Atrophic changes in the retinal pigment epithelium developed around the SRNVM treated with photodynamic therapy (PDT). Pseudoxanthoma elasticum may be associated with T2AIJT complicated by bilateral SRNVM. Further studies are needed to assess both efficacy and appropriate PDT regime in T2AIJT-related SRNVM, especially if associated with other conditions.

    Bilateral striopallidodentate calcinosis (BSPDC) mentioned in the literature as Fahr's disease (a misnomer), is characterized by symmetrical and bilateral intracerebral calcifications located in the basal ganglia with or without deposits in the dentate nucleus, thalamus, and white matter. This entity is usually asymptomatic but may be manifested by neurological symptoms. Idiopathic BSPDC can occur either as sporadic or autosomal dominant familial forms. Secondary presentations of BSPDC are associated with infections, neoplastic diseases, toxicological or traumatic factors, and metabolic disorders. We describe a case of generalized pustular psoriasis associated with secondary BSPDC owing to pseudohypoparathyroidism. Laboratory tests revealed hypocalcemia, hyperphosphatemia, and a normal serum level of parathormone. The correction of the phosphorus-calcium metabolism disorder produced clinical improvement.

    Many patients with idiopathic pulmonary fibrosis (IPF) complain of chronic refractory cough. Chronic cough is a distressing and disabling symptom with a major impact on quality of life. During recent years, progress has been made in gaining insight into the pathogenesis of cough in IPF, which is most probably "multifactorial" and influenced by mechanical, biochemical and neurosensory changes, with an important role for comorbidities as well. Clinical trials of cough treatment in IPF are emerging, and cough is increasingly included as a secondary end-point in trials assessing new compounds for IPF. It is important that such studies include adequate end-points to assess cough both objectively and subjectively. This article summarises the latest insights into chronic cough in IPF. It describes the different theories regarding the pathophysiology of cough, reviews the different methods to assess cough and deals with recent and future developments in the treatment of cough in IPF.

    2017-01-01

    Renal infarction is a rare cause of referral to the emergency department, with very low estimated incidence (0.004%–0.007%). Usually, it manifests in patients aged 60–70 with risk factors for thromboembolism, mostly related to heart disease, atrial fibrillation in particular. We report a case of idiopathic segmental renal infarction in a 38-year-old patient, presenting with acute abdominal pain with no previous known history or risk factors for thromboembolic diseases. Because of its aspecific clinical presentation, this condition can mimic more frequent pathologies including pyelonephritis, nephrolithiasis, or as in our case appendicitis. Here we highlight the extremely ambiguous presentation of renal infarct and the importance for clinicians to be aware of this condition, particularly in patients without clear risk factors, as it usually has a good prognosis after appropriate anticoagulant therapy.

    Summary Idiopathic cardiomyopathy (ICM) is a primary cardiac disorder associated with abnormalities of ventricular wall thickness, size of ventricular cavity, contraction, relaxation, conduction and rhythm. Over the past two decades, molecular genetic analyses have revealed that mutations in the various genes cause ICM and such information concerning the genetic basis of ICM enables us to speculate the pathogenesis of this heterogeous cardiac disease. This review focuses on the molecular pathogenesis, i.e., genetic abnormalities and functional alterations due to the mutations especially in sarcomere/cytoskeletal components, in three characteristic features of ICM, hypertrophic cardiomyopathy (HCM), dilated cardiomyopathy (DCM) and restrictive cardiomyopathy (RCM). Understanding the functional abnormalities of the sarcomere/cytoskeletal components, in ICM, has unraveled the function of these components not only as a contractile unit but also as a pivot for transduction of biochemical signals.

This review will begin with an introduction to the disease, followed by brief summaries of studies of gene expression in IPF and epigenetic marks associated with exposures relevant to IPF. The majority of the discussion will focus on epigenetic studies conducted so far in IPF, the limitations, challenges nd future directions in this field.

    Idiopathic pulmonary fibrosis (IPF) is a disease of unknown etiology with considerable morbidity and mortality. Cigarette smoking is one of the most recognized risk factors for development of IPF. Furthermore, recent work suggests that smoking may have a detrimental effect on survival of patients with IPF. The mechanism by which smoking may contribute to the pathogenesis of IPF is largely unknown. However, accumulating evidence suggests that increased oxidative stress might promote disease progression in IPF patients who are current and former smokers. In this review, potential mechanisms by which cigarette smoking affects IPF, the effects of cigarette smoking on accelerated loss of lung function in patients with IPF, key genetic studies evaluating the potential candidate genes and gene-environment (smoking) interaction, diagnosis, and treatment with emphasis on recently closed and ongoing clinical trials are presented.

In the updated classification, lymphoid interstitial pneumonia (LIP) was moved from major to rare IIPs, pleuroparenchymal fibroelastosis (PPFE) was newly included in the rare IIPs, acute fibrinous and organizing pneumonia (AFOP) and interstitial pneumonias with a bronchiolocentric distribution are recognized as rare histologic patterns, and unclassifiable IIP (UCIP) was classified as an IIP. However, recent reports indicate the areas of concern that may require further evaluation. Here, we describe the histopathologic features of the updated IIPs and their rare histologic patterns and also point out some of the issues to be considered in this context. PMID:26949346

    Idiopathic pulmonary fibrosis is a chronic fibrotic lung disease of unknown cause that occurs in adults and has a poor prognosis. Its epidemiology has been difficult to study because of its rarity and evolution in diagnostic and coding practices. Though uncommon, it is likely underappreciated both in terms of its occurrence (ie, incidence, prevalence) and public health impact (ie, health care costs and resource utilization). Incidence and mortality appear to be on the rise, and prevalence is expected to increase with the aging population. Potential risk factors include occupational and environmental exposures, tobacco smoking, gastroesophageal reflux, and genetic factors. An accurate understanding of its epidemiology is important, especially as novel therapies are emerging. PMID:24348069

    Idiopathic intracranial hypertension (IIH) is most often diagnosed in young obese females of childbearing years. The diagnosis is made based on the modified Dandy criteria and the exclusion of alternate causes of raised intracranial pressure. The focus of this review is to provide an overview of the diagnosis and treatment options for patients with IIH. There are long-term consequences for patients experiencing IIH, with visual loss being the most serious. We conclude that the diagnosis of IIH is not usually difficult. An ophthalmologic examination is essential in patients with IIH to monitor visual function. A neurologist or neurosurgeon may be needed at some point for medical and/or surgical intervention. © 2014 American Headache Society.

Functional therapies including physiotherapy are important components in the multidisciplinary teamwork and each phase of the disease requires different strategies. While in the active phase of the disease pain alleviation is the main focus, the inactive phase requires strategies for improving motility and function. During remission the aim is to regain general fitness by sports activities. These phase adapted strategies must be individually designed and usually require a combination of different measures including physiotherapy, occupational therapy, massage as well as other physical procedures and sport therapy. There are only few controlled studies investigating the effectiveness of physical therapies in JIA and many strategies are derived from long-standing experience. New results from physiology and sport sciences have contributed to the development in recent years. This report summarizes the basics and main strategies of physical therapy in JIA.

    Idiopathic pulmonary fibrosis (IPF) is a fibrosing interstitial lung disease associated with aging that is characterized by the histopathological pattern of usual interstitial pneumonia. Although an understanding of the pathogenesis of IPF is incomplete, recent advances delineating specific clinical and pathologic features of IPF have led to better definition of the molecular pathways that are pathologically activated in the disease. In this review we highlight several of these advances, with a focus on genetic predisposition to IPF and how genetic changes, which occur primarily in epithelial cells, lead to activation of profibrotic pathways in epithelial cells. We then discuss the pathologic changes within IPF fibroblasts and the extracellular matrix, and we conclude with a summary of how these profibrotic pathways may be interrelated.

    The term idiopathic is often used to describe a disease with no identifiable cause. It may be a diagnosis of exclusion; however, what specific minimum investigations need to be performed to define idiopathic is not always clear. This commentary describes the problems inherent in reaching a definition for the term idiopathic. There is limited literature describing methodology to define a condition with no clear diagnostic criteria. This article offers chronic pelvic pain (CPP) syndrome as an example, in which structured qualitative interviews, literature searches and group consensus discussions were undertaken to produce a working definition for idiopathic CPP. It is important to correctly develop these standardized definitions for use as outcome measures in research and as clinical indicators in healthcare.

    Harlequin syndrome, which is a rare disorder caused by dysfunction of the autonomic system, manifests as asymmetric facial flushing and sweating in response to heat, exercise, or emotional factors. The syndrome may be primary (idiopathic) with a benign course, or can occur secondary to structural abnormalities or iatrogenic factors. The precise mechanism underlying idiopathic harlequin syndrome remains unclear. Here, we describe a case of a 6-year-old boy who reported left hemifacial flushing and sweating after exercise. He had an unremarkable birth history and no significant medical history. Complete ophthalmological and neurological examinations were performed, and no other abnormalities were identified. Magnetic resonance imaging was performed to exclude lesions of the cerebrum and cervicothoracic spinal cord, and no abnormalities were noted. His final diagnosis was classic idiopathic harlequin syndrome. Herein, we report the first pediatric case of idiopathic harlequin syndrome in Korea. PMID:28018464

    Abstract The ultrastructural changes in diabetic and idiopathic gastroparesis are not well studied and it is not known whether there are different defects in the two disorders. As part of the Gastroparesis Clinical Research Consortium, full thickness gastric body biopsies from 20 diabetic and 20 idiopathic gastroparetics were studied by light microscopy. Abnormalities were found in many (83%) but not all patients. Among the common defects were loss of interstitial cells of Cajal (ICC) and neural abnormalities. No distinguishing features were seen between diabetic and idiopathic gastroparesis. Our aim was to provide a detailed description of the ultrastructural abnormalities, compare findings between diabetic and idiopathic gastroparesis and determine if patients with apparently normal immunohistological features have ultrastructural abnormalities. Tissues from 40 gastroparetic patients and 24 age- and sex-matched controls were examined by transmission electron microscopy (TEM). Interstitial cells of Cajal showing changes suggestive of injury, large and empty nerve endings, presence of lipofuscin and lamellar bodies in the smooth muscle cells were found in all patients. However, the ultrastructural changes in ICC and nerves differed between diabetic and idiopathic gastroparesis and were more severe in idiopathic gastroparesis. A thickened basal lamina around smooth muscle cells and nerves was characteristic of diabetic gastroparesis whereas idiopathic gastroparetics had fibrosis, especially around the nerves. In conclusion, in all the patients TEM showed abnormalities in ICC, nerves and smooth muscle consistent with the delay in gastric emptying. The significant differences found between diabetic and idiopathic gastroparesis offers insight into pathophysiology as well as into potential targeted therapies. PMID:21914127

    Although tonsilloliths are reported to be fairly common, florid cases casting distinct radiopaque shadows on panoramic radiographs are not often reported. This report illustrates such a case as an incidental finding in an asymptomatic 38-year-old female dental patient. Panoramic radiography revealed distinct radiopaque shadows over the ascending rami of the mandible bilaterally. These radiopacities were localized to the palatine tonsils by computerized tomographic inspection. Tonsillectomy was performed and tonsillolithiasis was confirmed by histopathologic examination.

    Bilateral patellae fractures represent a rare entity, accounting for approximately 2.9% of all lesions interesting in this anatomical district. In most cases found in the published work, they are described as stress fractures or as complications of chronic diseases such as osteoporosis, renal failure and secondary hyperparathyroidism. Although many pathogenetic mechanisms have been supposed, none have been proved for certain. Insufficiency fractures of the patellae are rare events and no data has been published on their incidence. We present a case of bilateral fracture of the patellae due to an indirect trauma occurring in an 85-year-old patient affected by Parkinson's disease, osteoporosis and diffuse degenerative osteoarthritis. X-ray of the knees (anteroposterior and lateral) and magnetic resonance imaging evaluation confirmed the fractures. The patient was treated conservatively. She had a good result, returning to her previous autonomous ambulation. This case is unusual because there was no direct trauma to the knees because of bilaterality, but confirmed previous observations about insufficiency fractures of patellae in the presence of comorbidity. Insufficiency fractures of patellae can be an insidious condition in elderly people. Prepatellar pain, a common symptom in the relapse phase of degenerative arthritis of the knee, should not be underestimated, particularly in patients with diseases influencing metabolism of bone and with an elevated risk of fall. A periodical clinical and instrumental follow up should be done in these patient. Moreover, we underline the necessity of a multidisciplinary approach.

    Recent findings suggest that vestibular information plays a significant role in anchoring the self to the body. Out-of-body experiences of neurological origin are frequently associated with vestibular sensations, and galvanic vestibular stimulation in healthy participants anchors the self to the body. Here, we provide the first objective measures of anchoring the self to the body in chronic bilateral vestibular failure (BVF). We compared 23 patients with idiopathic BVF to 23 healthy participants in a series of experiments addressing several aspects of visuo-spatial perspective taking and embodiment. In Experiment 1, participants were involved in a virtual “dot-counting task” from their own perspective or the perspective of a distant avatar, to measure implicit and explicit perspective taking, respectively. In both groups, response times increased similarly when the avatar’s and participant’s viewpoint differed, for both implicit and explicit perspective taking. In Experiment 2, participants named ambiguous letters (such as “b” or “q”) traced on their forehead that could be perceived from an internal or external perspective. The frequency of perceiving ambiguous letters from an internal perspective was similar in both groups. In Experiment 3, participants completed a questionnaire measuring the experienced self/body and self/environment “closeness”. Both groups reported a similar embodied experience. Altogether, our data show that idiopathic BVF does not change implicit and explicit perspective taking nor subjective anchoring of the self to the body. Our negative findings offer insight into the multisensory mechanisms of embodiment. Only acute peripheral vestibular disorders and neurological disorders in vestibular brain areas (characterized by strong multisensory conflicts) may evoke disembodied experiences. PMID:28107424

    To determine what percentage of diabetes insipidus (DI) in childhood is idiopathic and to assess the natural history of idiopathic DI. We conducted a retrospective chart review of 105 patients with DI who were born or had DI diagnosed between 1980-1989 at 3 medical centers. A second cohort of 30 patients from 6 medical centers in whom idiopathic DI was diagnosed after 1990 was evaluated retrospectively for subsequent etiologic diagnoses and additional hypothalamic/pituitary deficiencies and prospectively for quality of life. In the first cohort, 11% of patients had idiopathic DI. In the second cohort, additional hypothalamic/pituitary hormone deficiencies developed in 33%, and 37% received an etiologic diagnosis for DI. Health-related quality of life for all the patients with idiopathic DI was comparable with the healthy reference population. Only a small percentage of patients with DI will remain idiopathic after first examination. Other hormone deficiencies will develop later in one-third of those patients, and slightly more than one-third of those patients will have an etiology for the DI diagnosed. Long-term surveillance is important because tumors have been diagnosed as long as 21 years after the onset of DI. Quality of life for these patients is as good as the reference population.

    Idiopathic intracranial hypertension (IIH) has an estimated incidence of one to three people per 100,000 people per year, and occurs most commonly in obese, young women. IIH is associated with severe morbidity, notably due to a significant threat to sight and severe headache. Several different management options have been proposed. Conservative measures centre on weight loss. Pharmacological therapy includes use of diuretics. Refractory and sight-threatening cases demand surgical intervention, most often in the form of cerebrospinal fluid (CSF) diversion or optic nerve sheath fenestration. Other treatments include venous sinus stenting and bariatric surgery. To assess the effects of any intervention for IIH in any patient group. We searched CENTRAL (which contains the Cochrane Eyes and Vision Group Trials Register) (2015 Issue 6), Ovid MEDLINE, Ovid MEDLINE In-Process and Other Non-Indexed Citations, Ovid MEDLINE Daily, Ovid OLDMEDLINE (January 1946 to July 2015), EMBASE (January 1980 to July 2015), the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov) and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 22 July 2015. We included only randomised controlled trials (RCTs) in which any intervention was compared to placebo, or to another form of treatment, for people with a clinical diagnosis of IIH. Two review authors independently assessed the search results for trials to be included in the review. We resolved any discrepancies by third party decision. We identified two completed RCTs (enrolling a total of 211 participants and conducted in the UK and US) and two ongoing trials that met the inclusion criteria. Both completed trials compared acetazolamide to placebo, in conjunction with a weight loss intervention in

  6. Recurrent meningitis secondary to idiopathic oval window CSF leak.

    Bacterial meningitis remains a life-threatening infection even in the present antibiotic era; thus, any abnormality which predisposes a patient to a recurrence of this serious disease, must be identified and corrected. This report describes the histroy of a 12-year old boy with a profound neurosensory hearing loss, a related absence of vestibular function and a Mondini-type of temporal bone dysplasia who developed recurrent episodes of meningitis which were due to an idiopathic cerebrospinal fluid otorrhea. Even though the meningitis was labyrinthogenic in origin, the patient did not experience the associated symptoms of hearing loss and/or vertigo since the affected inner ear was clinically unreactive. By surgically exploring the middle ear, the presence of a cerebrospinal fluid otorrhea was confirmed. The leak was observed to be coming from a defect in the stapes footplate, and it was controlled by firmly packing the inner ear vestibule with muscle. A remarkable similarity exists between the patient described above and the 15 previously reported cases of meningitis due to a spontaneous cerebrospinal fluid otorrhea. Generally, the problem occurred in young children, the average age being 6.4 years; male and female were equally afflicted. All 15 previously reported cases had a severe neurosensory hearing loss which was unilateral in 10 individuals and bilateral in the other five. In 11 of the case reports, the vestibular function was evaluated, and the labyrinth was noted to be unreactive in the affected ear. An associated congenital abnormality of the inner ear was described in 11 of the patients reviewed. Anatomically, in 13 cases, the leak was observed to be coming from the oval window area. Other affected sites included one report of a fissure of the promontory and one report of a defect in the roof of the eustachian tube. Multiple surgical procedures were required in 11 of the 15 patients in order to identify the exact source of the otorrhea and to seal it

  7. Audiometric comparison of Lassa fever hearing loss and idiopathic sudden hearing loss: evidence for viral cause.

    A recently published prospective study on acute sensorineural deafness in Lassa fever among a West African population showed the audiometric pattern of a known virally induced hearing loss. Using the audiometric data from the patients with Lassa fever in that study, we analyzed and classified the initial hearing loss and final recovery into three groups by pure-tone average values and then did the same for 222 patients with idiopathic sudden hearing loss (SHL) in our study. Statistical analyses of the severity of initial hearing loss and the hearing recovery pattern indicate that the clinical course of our 222 patients with idiopathic SHL showed no statistically significant differences from the clinical course of the patients with Lassa fever. We found a marked difference in age, however, and a clinically significant difference in the incidence of bilateral hearing loss. In reviewing the literature on sudden sensorineural hearing loss, we found no apparent relation between severity of viral illness and initial hearing loss or subsequent recovery. Cummins et al. suggest that virally induced hearing loss in Lassa fever is linked to the host's immune response and not to the viremia. We thus propose a virally induced immune response mechanism for idiopathic sensorineural SHL. Further prospective studies are needed for verification.

    To determine the incidence of bilateral distal biceps tendon ruptures. A retrospective review of 321 patients who underwent operative repair of a distal biceps tendon rupture between 1988 and 2010 identified 26 patients with bilateral ruptures. We recorded patient age, mechanism of injury, time between symptom onset before the first surgery and subsequent contralateral symptoms, and time between surgeries. Twenty-two bilateral ruptures were confirmed intra-operatively, 3 by MRI, and 1 was lost to follow up. A total of 23 bilateral ruptures (92%) occurred in men. The average age at the initial rupture was 44 years (range, 29-74 y). The average age at subsequent rupture was 48 years (range, 36-79 y). Excluding the 2 women (age 72 and 79 y), the average age at the initial rupture was 42 years and the average age at subsequent rupture was 46 years. The average interval between ruptures was 4.1 years (range, 0.8-13.9 y). The initial rupture occurred in the dominant extremity in 12 cases (50%) and in the nondominant extremity in 10 cases (42%); in 3 patients (8%) the dominance was not documented or ambidextrous. Thirty-three percent were heavy laborers, 3 patients had a smoking history, and 1 patient reported a history of steroid use. Twenty-two patients (88%) had the second side repaired, where we noted that 12 (55%) of the second tendon ruptures were partial tears. The 8% cumulative incidence of bilateral biceps tendon ruptures in a consecutive series of biceps tendon repairs may be higher because not all patients were contacted, which introduced a sampling bias. This 8% rate is markedly higher than the reported rate of 1.2 per 100,000 for an isolated distal biceps tendon rupture. This implies that patients with a distal biceps tendon rupture are at risk for a rupture on the contralateral side. Prognostic III. Copyright © 2012 American Society for Surgery of the Hand.

    Idiopathic ophthalmodynia and idiopathic rhinalgia were described a few years ago. These conditions seem specific pain syndromes with a distinctive location in the eye or in the nose. We aimed to present a new prospective series in order to verify the consistency of these syndromes. We performed a descriptive study of all patients referred to our regional neurologic clinics from 2010 to 2014 because of facial pain exclusively felt in the eye or in the nose fulfilling the proposed diagnostic criteria for idiopathic ophthalmodynia and idiopathic rhinalgia. There were 9 patients with idiopathic ophthalmodynia and 7 patients with idiopathic rhinalgia, with a clear female preponderance, and a mean age at onset in the fifth decade. The pain was usually moderate and the temporal pattern was generally chronic. Only one patient reported accompaniments (hypersensitivity to the light and to the flow of air in the symptomatic eye). Preventive treatment with amitriptyline, pregabalin, or gabapentin was partially or totally effective. The clinical features of this new series parallels those of the original description, thus indicating that both idiopathic ophthalmodynia and idiopathic rhinalgia have clear-cut clinical pictures with excellent consistency both inter- and intra-individually. © 2015 American Headache Society.

    Acute renal failure due to bilateral ureteral obstruction is a rare complication after appendectomy in children. We report a case of bilateral ureteric obstruction in a 14-year-old boy nine days after surgery for an acute appendicitis. After saline-filling of the urinary bladder, transabdominal ultrasound demonstrated bilateral hydronephrosis of moderate degree. No abscess was found with CT but presence of millimetric stones on both distal ureters was shown, with bilateral calyceal dilatation. Cystoscopy revealed inflammatory changes in the bladder base. Following introduction of bilateral ureteric stents, there was rapid normalisation of urinary output and serum creatinine. PMID:26295001

    Abstract Etiologies for diffuse alveolar hemorrhage are wide and range from infectious to vasculitis and malignant processes. Idiopathic thrombocytopenic purpura is an autoimmune disorder characterized by persistent thrombocytopenia, with a relatively indolent course in young patients, but a more complicated progression and high associated mortality in the older patients. Diffuse alveolar hemorrhage, complicating idiopathic thrombocytopenic purpura, is a very uncommon association, with only 2 reported cases in the literature. We present a 69-year-old healthy woman presenting with petechial rash, progressive dyspnea, and bilateral alveolar infiltrates. She was found to have idiopathic thrombocytopenic purpura associated with diffuse alveolar hemorrhage. The patient had an excellent response to high doses of pulse steroids and immunoglobulins. A high index of suspicion for noninfectious pulmonary diseases should be considered in patients with autoimmune diseases presenting with pulmonary infiltrates and hypoxia. Flexible bronchoscopy with sequential lavage is a relatively safe procedure in patients with coagulopathy and should be attempted to detect and confirm the diagnosis; absence of hemoptysis should not preclude the diagnosis.

    Case report. To report bilateral pars fractures at L5 complicating a long fusion for adult idiopathic scoliosis in a patient with rheumatoid arthritis. To our knowledge, there are no reports in the literature regarding bilateral pars fractures at the end instrumented vertebrae of a long fusion at the lumbosacral junction, nor reports that have evaluated long spinal deformity corrections in patients with rheumatoid arthritis. The question of ending a long fusion at L5 or S1 is controversial, and a review is presented. We present the patient's history, physical examination, and radiographic findings; describe the surgical treatment and long-term follow-up; and provide a literature review. Bilateral pars fractures at the end instrumented vertebrae of a long construct (T4-L5) that we discovered were subsequently revised by extension of the fusion to the sacrum. Anterior structural support at L5-S1 was also provided. At the latest follow-up (46 months), the patient has had no recurrence of her symptoms. Her radiographs showed a stable construct without loss of alignment in the sagittal or coronal planes. Her rheumatoid arthritis continues to be treated with biologic, disease-modifying antirheumatic drugs. To our knowledge, this is the first report of the treatment and long-term outcome of a patient with rheumatoid arthritis and bilateral pars fractures at the end instrumented vertebrae (L5) of a long deformity correction construct.

    The purpose of this study was to evaluate the interocular symmetry of several biometric parameters between both eyes. The symmetry between the right and left eye of 397 subjects in 14 biometric parameters, spherical equivalent of refractive error (SE), Jackson crossed cylinder power of refractive error astigmatism with axes at 90° and 180° (RJ0) and at 45° and 135° (RJ45), best-corrected visual acuity (BCVA), average corneal curvature (CC), Jackson crossed cylinder power of corneal astigmatism (CJ0 and CJ45), corneal asphericity coefficient (Q), intraocular pressure (IOP), central corneal thickness (CCT), axial length (AL), anterior chamber depth (ACD), lens thickness (LT) and vitreous chamber depth (VCD), was assessed by comparative data analysis. Aside from RJ0 (p = 0.00), RJ45 (p = 0.02) and Q (p = 0.00), the overall interocular differences of other biometric parameters between fellow eyes were not significant (p > 0.05). The interocular correlation and Bland-Altman plots showed a good agreement between fellow eyes in 14 biometric parameters. Correlations between interocular differences in SE and that in RJ0 (p = 0.03), CC (p = 0.00), AL (p = 0.00) and VCD (p = 0.00) were statistically significant. There were similar strong linear relationships between refractive error astigmatism vectors and corneal astigmatism vectors in bilateral eyes. There were negative correlations of RJ45 and CJ45 between bilateral eyes. A potentially clinically important interocular symmetry in SE, BCVA, CC, CJ0, CJ45, IOP, CCT, AL, ACD, LT and VCD is found in this research, while the differences of RJ0, RJ45 and Q between left and right eyes seem a bit large. The negative interocular relationships of RJ45 and CJ45 demonstrate moderate mirror symmetry exists among fellow eyes. High interocular symmetry in bilateral eyes may be helpful in intraocular lens power calculation, intraocular pressure evaluation, post-operative visual acuity and refraction

  14. [Origin of bilateral-symmetrical animals (Bilateria)].

    2004-01-01

    The paper is an attempt to attack the old problem of the origin of Bilateria by the methods of evolutionary tetrad (i.e. combination of comparative anatomy, comparative embryology, paleontology, and molecular biology). Three groups of theories of classical comparative anatomy (planulod-turbellarian, archicoelomate, and metameric) are discussed. Comparative embryology brings out clearly that the ventral side of embryo comes from the blastoporal region in all groups of Bilateria (except Chordata, where the blastoporal region corresponds to the dorsal side that is come out of the upside-down morphology of chordates) and mouth and anus comes from the anterior and posterior ends of elongated blastopore. From the point of view of paleontology, some of vendian metazoans demonstrate transitional conditions between the Radiata and Bilateria. Vendian bilaterians are metameric organisms with normal or asymmetric position of segments and could be pictured as "bilateral coelenterates" creeping on the oral surface. In Cnidaria, the expression of homologues of "Brachyury", "goosecoid", and "fork head" genes are revealed in the circular region around the mouth. In Bilateria, these genes are expressed along the elongated blastopore and around the mouth and anus. These results support the old conception on the amphistomic origin of mouth and anus as well as the homology between the oral disc of cnidarians and ventral side of Bilateria. The combination of four mentioned approaches enables us to propose the conception of the origin of Bilateria from vendian bilateral coelenterates with numerous metameric pouches of gastral cavity. Bilaterian ancestors crawled on the oral disc (= ventral side). These ancestors gave rise to both phanerosoic cnidarians and triploblastic bilaterians. Cnidarian ancestors attached to bottom by the aboral pole with the resulting degradation of aboral nerve ganglion. Bilateral symmetry of anthozoans is considered to be primitive feature for cnidarians. In

    Idiopathic central serous chorioretinopathy (ICSC) is an uncommon disease with the potential to cause loss of visual acuity, decreased color vision, and decreased depth perception. These visual changes may become permanent and require removal of aviators from flight status. This study reviews 55 eyes of 47 USAF aviators with ICSC examined at the United States Air Force School of Aerospace Medicine (USAFSAM), Brooks AFB, TX. Clinical and aeromedical findings, both on initial and on follow-up ophthalmic examination were studied. Ninety-seven percent of aviators otherwise medically qualified were ultimately returned to flight status. Overall, 51% had recurrent episodes, 17% had bilateral disease, and 13% underwent laser photocoagulation. Visual acuity correlated with active disease, and there was a trend toward poor stereopsis and diminished color vision with worsening visual acuity. Eighty-six percent attained a final visual acuity of 20/20 or better. On final examination, 90% had normal stereopsis, 87% had normal color vision, and 49% had a normal central visual field. Eyes with recurrent disease tended to have degraded final visual acuity, stereopsis, color vision, and central visual field. The visual and aeromedical prognosis from a single attack of ICSC is generally favorable, but repeated attacks can lead to a significant decrease in visual functions that may jeopardize flying status.

  16. The effects of unilateral muscle fatigue on bilateral physiological tremor.

    finger tremor amplitude and EMG activity, coupled with the lack of any changes in tremor for the more proximal arm segments, indicate that these bilateral effects were mediated by an increase in the central neural drive to both limbs. Together this set of results challenges the general assumption of bilateral independence of tremor production, and further illustrate the task dependent nature of exercise-induced fatigue.

  17. Diagnosis and treatment of adolescent idiopathic scoliosis.

    PubMed

    Burton, Monique S

    2013-11-01

    Scoliosis is defined as a lateral curvature of the spine greater than 10 degrees on radiography that is typically associated with trunk rotation. The three major types of scoliosis are congenital, idiopathic, and neuromuscular. Idiopathic scoliosis is divided into three subcategories based on the age of onset. Infantile idiopathic scoliosis affects patients younger than 3 years, juvenile idiopathic scoliosis appears in children between 3 and 10 years, and adolescent idiopathic scoliosis (AIS) occurs in skeletally immature patients older than 10 years. AIS is the most common form of idiopathic scoliosis. Approximately 2% to 4% of children aged 10 to 16 years have some degree of spinal curvature. Although some researchers view routine screening for AIS as controversial, well-child examinations and sports physicals are an optimal time to evaluate for AIS in the clinical setting. In 2008, the American Academy of Orthopaedic Surgeons, the Scoliosis Research Society, the Pediatric Orthopaedic Society of North America, and the American Academy of Pediatrics convened a task force to review the issues related to scoliosis screening and issued an information statement concluding that although screening has limitations, the potential benefits that patients with idiopathic scoliosis receive from early treatment can be substantial. Recommendations are now that females are screened twice, at age 10 and 12 years, and males once at age 13 or 14 years. Screening during routine well-child examinations and/or school-based evaluations will help identify patients who need ongoing monitoring. The evaluation of curvatures in conjunction with the level of skeletal maturity will help to guide the management of the curvature. Copyright 2013, SLACK Incorporated.

    Electroconvulsive therapy (ECT) is the most effective treatment for patients suffering from severe or treatment-resistant major depressive disorder (MDD). Unfortunately its underlying neurobiological mechanisms are still unclear. One line of evidence indicates that the seizures produced by ECT induce or stimulate neuroplasticity effects. Although these seizures also affect the cortex, the effect of ECT on cortical thickness is not investigated until now. We acquired structural magnetic resonance imaging data in 19 treatment-resistant MDD patients before and after a bilateral ECT course, and 16 healthy controls at 2 time points, and compared changes in cortical thickness between the groups. Our results reveal that ECT induces significant, bilateral increases in cortical thickness, including the temporal pole, inferior and middle temporal cortex and the insula. The pattern of increased cortical thickness was predominant in regions that are associated with seizure onset in ECT. Post hoc analyses showed that the increase in thickness of the insular cortex was larger in responders than in non-responders, which may point to a specific relationship of this region with treatment effects of ECT.

    Bilateral cleft lip nose deformity is a multi-factorial and complex deformity which tends to aggravate with growth of the child, if not attended surgically. The goals of primary bilateral cleft lip nose surgery are, closure of the nasal floor and sill, lengthening of the columella, repositioning of the alar base, achieving nasal tip projection, repositioning of the lower lateral cartilages, and reorienting the nares from horizontal to oblique position. The multiplicity of procedures in the literature for correction of this deformity alludes to the fact that no single procedure is entirely effective. The timing for surgical intervention and its extent varies considerably. Early surgery on cartilage may adversely affect growth and development; at the same time, allowing the cartilage to grow in an abnormal position and contributing to aggravation of deformity. Some surgeons advocate correction of deformity at an early age. However, others like the cartilages to grow and mature before going in for surgery. With peer pressure also becoming an important consideration during the teens, the current trend is towards early intervention. There is no unanimity in the extent of nasal dissection to be done at the time of primary lip repair. While many perform limited nasal dissection for the fear of growth retardation, others opt for full cartilage correction at the time of primary surgery itself. The value of naso-alveolar moulding (NAM) too is not universally accepted and has now more opponents than proponents. Also most centres in the developing world have neither the personnel nor the facilities for the same. The secondary cleft nasal deformity is variable and is affected by the extent of the original abnormality, any prior surgeries performed and alteration due to nasal growth. This article reviews the currently popular methods for correction of nasal deformity associated with bilateral cleft lip, it's management both at the time of cleft lip repair and also secondarily

    A 12-year-old patient presented with a severe delay of eruption in permanent maxillary and mandibular incisors. On examination, there was over-retained primary teeth and delayed eruption of permanent teeth. Retained primary teeth showed light yellow discolouration whereas permanent teeth were distinct yellow with thin or little enamel. Subsequent imaging revealed all the premolars except maxillary left first premolar showed signs of intra-alveolar coronal resorption, nephrocalcinosis with bilateral multiple calculi and small papillary tip calcifications, marked increase in alkaline phosphatase. Subsequent dental treatment for restoring the functional and aesthetic requirement followed by appropriate treatment for renal problem was undertaken.

    Isolated submandibular swellings pose a diagnostic challenge to the practising otolaryngologist. We report an unusual case of mumps isolated to bilateral submandibular glands. We discuss the case and the literature surrounding this condition and remind clinicians that mumps should be considered as a diagnosis in the presence of submandibular gland swelling in the absence of typical parotid swelling associated with mumps. Early consideration of this differential diagnosis, serological testing and a multidisciplinary approach may help to clinch the diagnosis earlier and prevent spread of the virus. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Inguinal hernias are rare in females. The authors report a case of bilateral inguinal hernias in a 10-year-old female. On exploration, the patient was found to be having a sliding hernia containing incarcerated ovary as contents on both sides. Peroperatively the contents were reduced, the sac was transfixed at its base and the redundant sac was excised. The repair of this form of hernias is more difficult because of adhesions between the contents and the wall of the sac and risk of damage during dissection. A description of this clinical presentation in the pre operative assessment and operative management are discussed in this report. PMID:25918632

    The authors report a case of a 49-year-old woman presenting a Cushing's syndrome (January 1997). The Magnetic Resonance Image of the pituitary gland revealed a microadenoma without extension in the cavernous sinus and a partial empty sella. The computed tomography scan showed a discreet bilateral adrenal hyperplasia with a left nodule (23 mm in diameter) a second nodule was noted. These data suggested the eventuality of maconodular adrenocortical hyperplasia in long-standing Cushing's disease. We discuss the implications of this finding for diagnosis, treatment and follow-up.

    A 28-year-old woman presented at eight weeks and four days of gestation, according to her menstrual dates, complaining of painless vaginal bleeding for three days. Her urinary pregnancy test was positive. Initial transvaginal ultrasound demonstrated an irregular complex structure with a fluid filled centre in the right adnexum. Despite the diagnosis of a possible underlying unruptured right tubal ectopic pregnancy, she declined surgical intervention and was managed expectantly as an inpatient. When she complained of increasing abdominal pain with haemodynamic instability, an emergency laparotomy was performed and a diagnosis of bilateral tubal ectopic pregnancy was made.

    Telemanipulator system includes master robot manipulated by human operator, and slave robot performing tasks at remote location. Two robots electronically coupled so slave robot moves in response to commands from master robot. Teleoperation greatly enhanced if forces acting on slave robot fed back to operator, giving operator feeling he or she manipulates remote environment directly. Main advantage of bilateral impedance control: enables arbitrary specification of desired performance characteristics for telemanipulator system. Relationship between force and position modulated at both ends of system to suit requirements of task.

    New insights have expanded the influence of the vestibular system to the regulation of circadian rhythmicity. Indeed, hypergravity or bilateral vestibular loss (BVL) in rodents causes a disruption in their daily rhythmicity for several days. The vestibular system thus influences hypothalamic regulation of circadian rhythms on Earth, which raises the question of whether daily rhythms might be altered due to vestibular pathology in humans. The aim of this study was to evaluate human circadian rhythmicity in people presenting a total bilateral vestibular loss (BVL) in comparison with control participants. Nine patients presenting a total idiopathic BVL and 8 healthy participants were compared. Their rest-activity cycle was recorded by actigraphy at home over 2 weeks. The daily rhythm of temperature was continuously recorded using a telemetric device and salivary cortisol was recorded every 3 hours from 6:00AM to 9:00PM over 24 hours. BVL patients displayed a similar rest activity cycle during the day to control participants but had higher nocturnal actigraphy, mainly during weekdays. Sleep efficiency was reduced in patients compared to control participants. Patients had a marked temperature rhythm but with a significant phase advance (73 min) and a higher variability of the acrophase (from 2:24 PM to 9:25 PM) with no correlation to rest-activity cycle, contrary to healthy participants. Salivary cortisol levels were higher in patients compared to healthy people at any time of day. We observed a marked circadian rhythmicity of temperature in patients with BVL, probably due to the influence of the light dark cycle. However, the lack of synchronization between the temperature and rest-activity cycle supports the hypothesis that the vestibular inputs are salient input to the circadian clock that enhance the stabilization and precision of both external and internal entrainment.

    We report the case of a 32-year-old woman with a history of increased sleep need and difficulty waking up; the diagnosis of idiopathic hypersomnia was hypothesized. During ambulatory polysomnography (PSG), the patient presented an episode characterized by loss of consciousness and jerking of the four limbs. A video-PSG monitoring was performed and the patient showed unresponsiveness and drowsiness at 7 a.m. During the episode, EEG showed theta-delta diffuse activity, and blood glucose level was 32 mg dl(-1). The diagnosis of insulinoma was then assumed; CT scan showed a hypodense mass into the pancreatic tail, and a partial pancreasectomy was performed. The described symptoms disappeared, and 5 years later the findings of a complete clinical and neurophysiological examination were negative. The clinical picture of insulinoma presenting with paroxysmal disorders has been previously described; however, whereas hypersomnia is uncommon, in the current case it represents the main symptom. Clinicians should keep in mind that neuroglycopenia should be considered in the differential diagnosis of patients with hypersomnia, particularly if the clinical scenario does not conform to standard criteria.

    2014-01-01

    Idiopathic pulmonary fibrosis (IPF) is a complex lung disease of unknown etiology. Development of IPF is influenced by both genetic and environmental factors. Recent work by our and other groups has identified strong genetic predisposition factors for the development of pulmonary fibrosis while cigarette smoke remains the most strongly associated environmental exposure risk factor. Gene expression profiling studies of IPF lung have taught us quite a bit about the biology of this fatal disease and those in peripheral blood have provided important biomarkers. However, epigenetic marks may be the missing link that connects the environmental exposure in genetically predisposed individuals to transcriptional changes associated with disease development. Moreover, epigenetic marks represent a promising therapeutic target for IPF. In this review, we will introduce the disease, summarize genetic and gene expression studies in IPF, discuss exposures relevant to IPF and known epigenetic changes associated with cigarette smoke exposure, and summarize epigenetic studies conducted so far in IPF. We will end by discussing limitations, challenges and future opportunities in this field. PMID:24746870

  10. Bone Disease and Idiopathic Hypercalciuria

    2008-01-01

    Observational and epidemiological studies alike have demonstrated that idiopathic hypercalciuric (IH) stone-forming patients typically demonstrate bone mineral density scores significantly less than those observed for age- and gender-matched normal subjects or those for non-hypercalciuric stone-forming patients. Most of these studies have relied on changes in bone mineral density (BMD) and have not explored the mechanism(s) involved. There have been a small number of studies that have relied on dynamic bone histomorphometry to ascertain the nature of the bone defect in IH patients. When performed, these studies have clearly demonstrated increased bone resorption and high bone turnover in patients with fasting hypercalciuria while suppressed bone formation indices are the most consistent finding in patients with the absorptive variant of IH. The causes of this apparent difference in bone remodeling between the two variants of IH is still uncertain. Available evidence suggests that potential mechanisms may be dependent in large part to genetic, metabolic, and nutritional causes of hypercalciuria and bone loss in patients with IH. PMID:18359394

    2011-01-01

    Fistula-in-ano is the most common form of perineal sepsis. Typically, a fistula includes an internal opening, a track, and an external opening. The external opening might acutely appear following infection and/or an abscess, or more insiduously in a chronic manner. Management includes control of infection, assessment of the fistulous track in relation to the anal sphincter muscle, and finally, definitive treatment of the fistula. Fistulotomy was the most commonly used mode of management, but concerns about post-fistulotomy incontinence prompted the use of sphincter preserving techniques such as advancement flaps, fibrin glue, collagen fistula plug, ligation of the intersphincteric fistula track, and stem cells. Many descriptive and comparative studies have evaluated these different techniques with variable outcomes. The lack of consistent results, level I evidence, or long-term follow-up, as well as the heterogeneity of fistula pathology has prevented a definitive treatment algorithm. This article will review the most commonly available modalities and techniques for managing idiopathic fistula-in-ano. PMID:21876614

    Idiopathic normal pressure hydrocephalus (iNPH) is a late-onset surgically alleviated, progressive disease. We characterize a potential familial subgroup of iNPH in a nation-wide Finnish cohort of 375 shunt-operated iNPH-patients. The patients were questionnaired and phone-interviewed, whether they have relatives with either diagnosed iNPH or disease-related symptomatology. Then pedigrees of all families with more than one iNPH-case were drawn. Eighteen patients (4.8%) from 12 separate pedigrees had at least one shunt-operated relative whereas 42 patients (11%) had relatives with two or more triad symptoms. According to multivariate logistic regression analysis, familial iNPH-patients had up to 3-fold risk of clinical dementia compared to sporadic iNPH patients. This risk was independent from diagnosed Alzheimer's disease and APOE ε4 genotype. This study describes a familial entity of iNPH offering a novel approach to discover the potential genetic characteristics of iNPH. Discovered pedigrees offer an intriguing opportunity to conduct longitudinal studies targeting potential preclinical signs of iNPH. Copyright © 2016 Elsevier B.V. All rights reserved.

  13. Scrotal calcinosis: idiopathic or dystrophic?

    2010-02-15

    Scrotal calcinosis is a rare benign local process characterized by multiple, painless, hard scrotal nodules in the absence of any systemic metabolic disorder. Histological examination reveals extensive deposition of calcium in the dermis, which may be surrounded by histiocytes and an inflammatory giant cell reaction. Numerous theories have been propounded to explain the pathogenesis of this condition, but the principal debate revolves around whether the calcium is deposited at the site of previous epithelial cysts or the calcified nodules are purely idiopathic. This is the largest study of scrotal calcinosis to date with 100 cases, on which clinical, biochemical, radiological, cytopathological, and histopathological examinations were conducted. The histological picture shows a continuous spectrum of changes ranging from intact epithelial cysts (41.0%) - both normal and inflamed; through inflamed cysts containing calcific material in the lumen but with intact cyst wall (53.0%); calcified inflamed cysts with partial epithelial lining (11.0%); to 'naked' calcium deposits lying in the dermis (100%), sometimes compressing surrounding collagen fibres to form a pseudocyst (56.0%). The presence of normal values of calcium and phosphorus along with this spectrum of changes in histology both support the theory that these form by dystrophic calcification of epithelial cysts in a progression that involves inflammation, rupture, calcification and obliteration of the cyst wall.

    Despite its high prevalence, the etiology underlying idiopathic scoliosis remains unclear. Although initial scrutiny has focused on genetic, biochemical, biomechanical, nutritional and congenital causes, there is growing evidence that aberrations in the vestibular system may play a role in the etiology of scoliosis. In this article, we discuss putative mechanisms for adolescent idiopathic scoliosis and review the current evidence supporting a role for the vestibular system in adolescent idiopathic scoliosis. A comprehensive search of the English literature was performed using PubMed ( http://www.ncbi.nlm.nih.gov/pubmed ). Research articles studying interactions between adolescent idiopathic scoliosis and the vestibular system were selected and evaluated for inclusion in a literature review. Eighteen manuscripts of level 3-4 clinical evidence to support an association between adolescent idiopathic scoliosis (AIS) and dysfunction of the vestibular system were identified. These studies include data from physiologic and morphologic studies in humans. Clinical data are supported by animal model studies to suggest a causative link between the vestibular system and AIS. Clinical data and a limited number of animal model studies suggest a causative role of the vestibular system in AIS, although this association has not been reproduced in all studies.

    To evaluate the efficacy of zonisamide as a monotherapy in dogs with idiopathic epileptic seizure. The experiment was conducted on 10 dogs with idiopathic epilepsy that were treated at the Seoul National University Hospital for Animals. A diagnosis was conducted based on physical and neurologic examination, complete blood count and chemical analysis, magnetic resonance imaging and cerebrospinal fluid analyses. Idiopathic epilepsy was diagnosed when all of these examinations were normal. Oral zonisamide was administrated to 10 dogs with idiopathic epilepsy at 5-15 mg/kg per os every 12 h to achieve a concentration of zonisamide in serum of 10-40 μg/mL. The frequency of seizures before and after the administration of zonisamide therapy was recorded and the concentrations of zonisamide in serum were measured. Six (60%) of the dogs were favourable responders to treatment, showing a ≥50% reduction in monthly frequency of seizures. Of the remaining four, two dogs did not show a reduction and the other two showed an increase in frequency of seizures. The mean dosage of zonisamide for favourable responders was 7.92 (SD 3.79) mg/kg, which was administered orally twice a day. Only one dog, which was one of the unfavourable responders in the whole study, experienced mild side effects. Among the dogs treated with oral zonisamide, 60% responded favourably. The effect of zonisamide as an anticonvulsant drug was demonstrated in this study. Based on these results, zonisamide monotherapy is effective in some dogs with idiopathic epilepsy.

    Retinoblastoma (RB) is the most frequent solid tumor in the Instituto Nacional de Pediatría, México (INP). The bilateral presentation occurs in 25% of all patients. We present some epidemiological data of this form of the disease, in learn these epidemiological variables in our series. We reviewed the clinical charts from 1972 to 1994. We analyzed age, sex, timing of presentation of the second affected eye, positive family history, clinical staging, and the development of secondary malignancies. A total of 105 cases were detected from 412 RB total cases (25%). We observed a male predominance 1.6:1.0 p = 0.04 versus females. The clinical staging showed: retinal stage 9/102, ocular stage 58/102, orbital stage 26/102 and non classified 9/102 p < 0.00001. The asynchronous form is a rare presentation in our experience: 16/105 cases p = 0.00001 (15%). Only 16/105 patients had a positive family history of RB (15%). We found 2 of 105 cases with secondary malignancies (0.01%). The asynchronous form constitutes a rare presentation. We cannot explain the etiology for the high prevalence of bilateral disease. The frequency of secondary malignancies is lower than that reported in the literature.

    1. Small animals (rat and guinea pig) vagotomized in the neck die within a period of hours, the lungs showing extensive congestion and edema. 2. Tracheotomy permits appreciably longer survival with minimal lung changes approximating those seen in the control animals. 3. Intrathoracic vagotomy (sparing the recurrent laryngeal nerve) on one side, and cervical vagotomy on the other, permits almost indefinite survival (guinea pig and rabbit), unless laryngeal paralysis from the unilateral denervation produces respiratory obstruction (rat, guinea pig, and rabbit). 4. Pulmonary edema following bilateral vagotomy probably results primarily from respiratory obstruction. It is suggested that circulatory failure may also be a factor of some importance. The rôle of vagotomy itself is considered in relationship to these two phenomena. 5. The reaction of smaller animals to bilateral vagotomy, with regard to lung changes, apparently differs in no way from that of the larger animals, but is less readily demonstrated because of the smaller diameters of the air passages.

    A 35-year-old man presented with asymptomatic eruption on both forearms and lower aspects of the legs for 6 months. The lesions first appeared on his inner aspects of the wrist, the dorsal surface of the hands, and legs and progressed to involve proximal aspects of the extremities. There was no significant past history. On examination, multiple pearly white papules and depigmented atrophic plaques were found bilaterally on the flexors of the arms and the extensors of the legs. The lesions were arranged in a linear manner, following the lines of Blaschko (Figures 1 and 2). The surface of the atrophic plaques was notable for prominent telangiectasia, giving an erythematous appearance. The genitalia, oral cavity, palms, and soles were spared. Systemic examination was noncontributory. Lichen striatus and extragenital lichen sclerosus (ELS) were considered the differential diagnosis. Clinically, the age of the patient, the absence of scaling, and the presence of atrophic plaques and telangiectasia were in favor of ELS. A punch biopsy from an atrophic plaque was performed, and it revealed hyperkeratosis, atrophic epidermis, basal layer vacuolar degeneration, mild lymphocytic infiltration in the dermis, edema, and homogenization of collagen of the upper portion of the dermis (Figures 3 and Figure 4). Histopathologic findings were consistent with lichen sclerosus. A diagnosis of bilateral zosteriform ELS was made.

  19. Bilateral internal thoracic artery grafting

    PubMed Central

    2013-01-01

    The effectiveness of the left internal mammary artery graft to the anterior descending coronary artery as a surgical strategy has been shown to improve the survival rate and decrease the risk of adverse cardiac events in patients undergoing coronary bypass surgery. These clinical benefits appear to be related to the superior short and long-term patency rates of the internal thoracic artery graft. Although the advantages of using of both internal thoracic arteries (ITA) for bypass grafting have taken longer to prove, recent results from multiple data sets now support these findings. The major advantage of bilateral ITA grafting appears to be improved survival rate, while the disadvantages of complex ITA grafting include the increased complexity of operation, and an increased risk of wound complications. While these short-term disadvantages have been mitigated in contemporary surgical practice, they have not eliminated. Bilateral ITA grafting should be considered the procedure of choice for patients undergoing coronary bypass surgery that have a predicted survival rate of longer than ten years. PMID:23977627

    Speckle noise negatively affects medical ultrasound image shape interpretation and boundary detection. Speckle removal filters are widely used to selectively remove speckle noise without destroying important image features to enhance object boundaries. In this article, a fully automatic bilateral filter tailored to ultrasound images is proposed. The edge preservation property is obtained by embedding noise statistics in the filter framework. Consequently, the filter is able to tackle the multiplicative behavior modulating the smoothing strength with respect to local statistics. The in silico experiments clearly showed that the speckle reducing bilateral filter (SRBF) has superior performances to most of the state of the art filtering methods. The filter is tested on 50 in vivo US images and its influence on a segmentation task is quantified. The results using SRBF filtered data sets show a superior performance to using oriented anisotropic diffusion filtered images. This improvement is due to the adaptive support of SRBF and the embedded noise statistics, yielding a more homogeneous smoothing. SRBF results in a fully automatic, fast and flexible algorithm potentially suitable in wide ranges of speckle noise sizes, for different medical applications (IVUS, B-mode, 3-D matrix array US).

The authors herein describe a rare case of bilaterally symmetrical facial synkinesis with video documentation and modified blink reflex. A 35-year-old gentleman presented with numbness involving right half of his face for 8 months and abnormal stretching sensations over both sides of his nose for one and a half months. Sensory and motor involvement of the right trigeminal nerve was detected along with bilaterally symmetrical facial synkinesis involving orbicularis oculi and nasalis. R(1) and R(2) responses consistent with mis-reinnervation were recorded on the left-side using orbicularis oculi and nasalis muscles. Skin biopsy revealed acid-fast bacilli and sural nerve biopsy, the presence of granulomas. After 3 months of follow-up on WHO multi-drug therapy, an improvement in facial sensations was observed but without any change in facial synkinetic movements.

    Familial idiopathic basal ganglia calcification (Fahr`s disease) is a rare neurodegenerative disorder characterized by symmetrical and bilateral calcification of the basal ganglia. Calcifications may also occur in other brain regions such as dentate nucleus, thalamus, and cerebral cortex. Both familial and non-familial cases of Fahr`s disease have been reported, predominantly with autosomal-dominant fashion. The disease has a wide range of clinical presentations, predominantly with neuropsychiatric features and movement disorders. Psychiatric features reported in the literature include: cognitive impairment, depression, hallucinations, delusions, manic symptoms, anxiety, schizophrenia-like psychosis, and personality change. Other clinical features include: Parkinsonism, ataxia, headache, seizures, vertigo, stroke-like events, orthostatic hypotension, tremor, dysarthria, and paresis. Fahr`s disease should be considered in the differential diagnosis of psychiatric symptoms, particularly when associated with movement disorder. The disease should be differentiated from other conditions that can cause intracranial calcification. No specific treatment is currently available. Further research is needed to bridge the gap existing in our current knowledge of the prevalence, etiology, symptoms, and treatment of Fahr`s disease.

    Diffuse idiopathic pulmonary neuroendocrine cell hyperplasia (DIPNECH) is a rare clinical condition with only about 100 cases reported in the literature. It is characterized by primary hyperplasia of pulmonary neuroendocrine cells (PNECs) which are specialized epithelial cells located throughout the entire respiratory tract, from the trachea to the terminal airways. DIPNECH appears in various forms that include diffuse proliferation of scattered neuroendocrine cells, small nodules, or a linear proliferation. It is usually seen in middle-aged, nonsmoking women with symptoms of cough, dyspnea, and wheezing. We present a 45-year-old, nonsmoking woman who presented with symptoms of DIPNECH associated with bilateral pulmonary nodules and left hilar adenopathy. Of interest, DIPNECH in our patient was associated with metastatic pulmonary carcinoids, papillary carcinoma of the left breast, oncocytoma and angiomyolipoma of her left kidney, and cortical nodules suggestive of tuberous sclerosis. She had video assisted thoracoscopic surgery (VATS), modified radical mastectomy with reconstruction, and radical nephrectomy. She is currently symptom-free most of the time with over two years of follow-up. PMID:26609460

    PubMed

    1998-07-01

    Idiopathic pulmonary haemosiderosis (IPH) is a rare clinical entity characterized by recurrent episodes of diffuse alveolar haemorrhage, often presenting with haemoptysis. Many patients have iron deficiency anaemia due to deposition of haemosiderin iron in the alveoli, and eventually develop moderate pulmonary fibrosis. Typically, intensive search for an aetiology ends up negative. There is no evidence of pulmonary vasculitis or capillaritis. The aetiology is obscure, but may be an immunological or toxic mechanism causing a defect in the basement membrane of the pulmonary capillary. IPH affects both children and adults. During an acute episode, a chest X-ray demonstrates bilateral, alveolar infiltrates. Sputum examination discloses haemosiderin-laden alveolar macrophages. Diagnosis is established by lung biopsy (fiber-optic or thoracoscopic), showing large numbers of haemosiderin-laden macrophages in the alveoli and without evidence of capillaritis or deposition of immunoglobulins. Corticosteroids and/or immunosuppressive drugs may be effective during an acute bleeding episode, and may in some patients improve symptoms and prognosis on the long-term, but the response to treatment displays great interindividual variation.

    The objective of this study was to analyze some clinical and epidemiologic aspects, as well as the follow up of 180 patients with Bell's palsy. In the study population there was a predominance of female (66.7%). Two peaks of incidence in the age distribution were identified: third-fourth and sixth decades of life. In the group of 180 patients there were 198 events of facial paralysis, 17 recurrences and in one patient the paralysis was bilateral at the onset. In 15 patients (8.3%) there were recurrences of the facial paralysis, in 12 cases (70.6%) the recurrences were ipsilateral. The left side of the face was involved in 55.6% of the cases. In eight patients the paralysis occurred during pregnancy (n=5) or puerperium (n=3). As associated conditions we found: arterial hypertension (11.7%), diabetes mellitus (11.1%), pregnancy or puerperium (4.4%; 6.7% in the women), and neurocysticercosis (1.1%). In 72.8% of the cases no association with such conditions was found. In 22.8% of the patients some kind of sequelae were identified: hemifacial spasm (12.8%), partial recovery of the motor deficit (10.6%), syndrome of the crocodile tears (3.3%), sincinetic contraction (2.8%), and the Marcus Gunn inverse phenomenon (1.1%). In conclusion, this study shows that the idiopathic facial paralysis may lead to important sequelae in more than 20% of the patients.

  6. The diagnosis and management of patients with idiopathic osteolysis

    PubMed Central

    2011-01-01

    Idiopathic osteolysis or disappearing bone disease is a condition characterized by the spontaneous onset of rapid destruction and resorption of a single bone or multiple bones. Disappearing bone disorder is a disease of several diagnostic types. We are presenting three patients with osteolysis who have different underlying pathological features. Detailed phenotypic assessment, radiologic and CT scanning, and histological and genetic testing were the baseline diagnostic tools utilized for diagnosis of each osteolysis syndrome. The first patient was found to have Gorham-Stout syndrome (non-heritable). The complete destruction of pelvic bones associated with aggressive upward extension to adjacent bones (vertebral column and skull base) was notable and skeletal angiomatosis was detected. The second patient showed severe and aggressive non-hereditary multicentric osteolysis with bilateral destruction of the hip bones and the tarsal bones as well as a congenital unilateral solitary kidney and nephropathy. The third patient was phenotypically and genotypically compatible with Winchester syndrome resulting in multicentric osteolysis (autosomal recessive). Proven mutation of the (MMP2-Gen) was detected in this third patient that was associated with 3MCC deficiency (3-Methylcrontonyl CoA Carboxylase deficiency). The correct diagnoses in our 3 patients required the exclusion of malignant osteoclastic tumours, inflammatory disorders of bone, vascular disease, and neurogenic arthropathies using history, physical exam, and appropriate testing and imaging. This review demonstrates how to evaluate and treat these complex and difficult patients. Lastly, we described the various management procedures and treatments utilized for these patients.

    Idiopathic hypertrophic pachymeningitis is a rare inflammatory condition with diffuse thickening of the dura mater, which may cause a compressive effect or vascular compromise. We report on a 28-year-old Chinese woman with a history of granulomatous mastitis 7 years previously and oligomenorrhoea, headache, blurred vision, and raised prolactin level 2 years previously, that was diagnosed as prolactinoma and treated conservatively with bromocriptine. However, she had recurrent bilateral vision loss when the bromocriptine was stopped. Her symptoms were resolved by high-dose steroid injection but remained steroid-dependent. Serial magnetic resonance imaging scan showed progressive diffuse thickening of the pachymeningitis with disappearance of pituitary apoplexy. Lumbar puncture showed lymphocytosis with no organisms. Open biopsy of the meninges was performed and histology showed features of inflammatory infiltrates and vasculitis. This is an unusual presentation of a rare condition in this age-group, with co-existing granulomatous mastitis and chronic otitis media, and is a diagnostic challenge mimicking pituitary macroadenoma and meningioma in initial magnetic resonance imaging scans.

  8. Bell's palsy before Bell: Evert Jan Thomassen à Thuessink and idiopathic peripheral facial paralysis.

    PubMed

    2009-11-01

    Bell's palsy is the eponym for idiopathic peripheral facial paralysis. It is named after Sir Charles Bell (1774-1842), who, in the first half of the nineteenth century, discovered the function of the facial nerve and attracted the attention of the medical world to facial paralysis. Our knowledge of this condition before Bell's landmark publications is very limited and is based on just a few documents. In 1804 and 1805, Evert Jan Thomassen à Thuessink (1762-1832) published what appears to be the first known extensive study on idiopathic peripheral facial paralysis. His description of this condition was quite accurate. He located several other early descriptions and concluded from this literature that, previously, the condition had usually been confused with other afflictions (such as 'spasmus cynicus', central facial paralysis and trigeminal neuralgia). According to Thomassen à Thuessink, idiopathic peripheral facial paralysis and trigeminal neuralgia were related, being different expressions of the same condition. Thomassen à Thuessink believed that idiopathic peripheral facial paralysis was caused by 'rheumatism' or exposure to cold. Many aetiological theories have since been proposed. Despite this, the cold hypothesis persists even today.

  9. Stature and idiopathic scoliosis. A prospective study.

    1985-03-01

    A study of 130 scoliotic children with curves measuring 10 degrees or more has been performed in order to elucidate the importance of stature, growth and development. Girls with adolescent idiopathic curves measuring 15 degrees or more were taller than girls with smaller idiopathic curves and taller than those whose scoliosis was secondary to leg-length inequality (pelvic tilt scoliosis). No differences were observed as regards growth velocity or development. The increased standing height may be genetic but the uncoiling effect of the normal kyphosis to give a flat lateral profile is a more likely cause. The familial trend in idiopathic scoliosis may therefore be explained by the genetically determined shape of the spine in the median (sagittal) plane.

    2015-08-01

    Syncope due to idiopathic AV block is characterized by: 1) ECG documentation (usually by means of prolonged ECG monitoring) of paroxysmal complete AV block with one or multiple consecutive pauses, without P-P cycle lengthening or PR interval prolongation, not triggered by atrial or ventricular premature beats nor by rate variations; 2) long history of recurrent syncope without prodromes; 3) absence of cardiac and ECG abnormalities; 4) absence of progression to persistent forms of AV block; 5) efficacy of cardiac pacing therapy. The patients affected by idiopathic AV block have low baseline adenosine plasma level values and show an increased susceptibility to exogenous adenosine. The APL value of the patients with idiopathic AV block is much lower than patients affected by vasovagal syncope who have high adenosine values.

    2009-02-01

    Idiopathic scoliosis is a lateral curvature of the spine greater than 10 degrees for which there is no known cause. This paper reviews the current literature on the appropriate evaluation and treatment of patients with idiopathic scoliosis. Improved technology and surgical techniques are allowing improved curve correction and improved quality of life for these patients. Specifically, the pedicle screw construct can provide excellent curve correction and stabilization for spinal deformities. Idiopathic scoliosis is a diagnosis of exclusion and the approach to a patient with scoliosis should aim toward ruling out other possible causes. In those patients with scoliosis necessitating treatment, bracing should be the first line of treatment and these patients should be followed up closely to track curve progression. Patients who fail conservative management may undergo spinal fusion with pedicle screw instrumentation. Vigilant monitoring and thorough evaluation of scoliosis patients can steer patients toward appropriate management in a judicious manner preventing the significant medical morbidity and deformity that scoliosis can insidiously inflict.

    Knee injuries in young athletes include not only the typical adult bone injuries, ligament and cartilage, but also the growth plate lesions. Osteochondroses are idiopathic, self-limited disturbance of enchondral ossification in which a rapid growth spurt is present. The patella could be affected by two different kinds of osteochondroses: Kohler syndrome and Sinding-Larsen-Johansson. Here we are reporting the first case of simultaneous location of osteochondroses of the two ossification centers of both patella. A 9-year-old boy, competitive skater, presented a history of anterior knee pain involving both knees. Standard X-rays, axial patellar view, MRI and arthro-MR were performed. In order to follow the natural history of the pathology and the evolution of the healing, examinations at 2 years were repeated. We proposed the young skater a medical and a physiotherapeutic treatment based on unloading, isometric exercises, NSAID. As the symptoms improve a gradual return to competitive sports activity was allowed. The case mentioned above can be considered an atypical case because the patient suffered for a bilateral knee osteochondroses, involving simultaneously the primary ossification centre (Kohler syndrome) and the secondary ossification centre (Larsen syndrome) of the patella.

    Bilateral striopallidodentate calcinosis is characterized by calcification of the basal ganglia and other gray matter structures. We describe a 16-year-old boy with paroxysmal kinesigenic dyskinesia. He exhibited mineralization in the basal ganglia, posterior thalami, and dentate nuclei bilaterally, and was diagnosed with sporadic bilateral striopallidodentate calcinosis. The paroxysmal kinesigenic dyskinesia responded to low-dose treatment with carbamazepine (200 mg/day).

    Unilateral sternocleidomastoid muscle contracture causing torticollis and other secondary deformities such as facial scoliosis, plagiocephaly and scoliosis of cervical spine are well known. The aetiology and pathogenesis is still intriguing. Although unilateral contracture of sternocleidomastoid is seen quite often, bilateral sternocleidomastoid contracture is almost unheard of. A review of the English literature revealed no cases of bilateral congenital sternocleidomastoid contracture being reported. We present a case report of a 19-year-old girl with congenital bilateral sternocleidomastoid contracture.

    Background Typically juvenile idiopathic arthritis (JIA)-associated uveitis (further referred as ‘JIA-uveitis’) has its onset in childhood, but some patients suffer its, sometimes visual threatening, complications or ongoing disease activity in adulthood. The objective of this study was to analyze uveitis activity, complications and visual prognosis in adulthood. Methods In this multicenter study, 67 adult patients (129 affected eyes) with JIA-uveitis were retrospectively studied for best corrected visual acuity, visual fields, uveitis activity, topical/systemic treatments, ocular complications, and ocular surgeries during their 18th, 22nd and 30th year of life. Because treatment strategies changed after the year 1990, outcomes were stratified for onset of uveitis before and after 1990. Results Sixty-two of all 67 included patients (93%) had bilateral uveitis. During their 18th life year, 4/52 patients (8%) had complete remission, 28/52 (54%) had uveitis activity and 37/51 patients (73%) were on systemic immunomodulatory treatment. Bilateral visual impairment or legal blindness occurred in 2/51 patients (4%); unilateral visual impairment or legal blindness occurred in 17/51 patients (33%) aged 18 years. The visual prognosis appeared to be slightly better for patients with uveitis onset after the year 1990 (for uveitis onset before 1990 (n = 7) four patients (58%) and for uveitis onset after 1990 (n = 44) 13 patients (30%) were either visual impaired or blind). At least one ocular surgery was performed in 10/24 patients (42%) between their 18th and 22nd year of life. Conclusions Bilateral visual outcome in early adulthood in patients with JIA-uveitis appears to be fairly good, although one third of the patients developed one visually impaired or blind eye. However, a fair amount of the patients suffered from ongoing uveitis activity and needed ongoing treatment as well as surgical interventions. Awareness of these findings is important for ophthalmologists and

    Non-specific interstitial pneumonia (NSIP) is an interstitial lung disease that may be idiopathic or secondary to connective tissue disease, toxins or numerous other causes. Idiopathic NSIP is a rare diagnosis and requires exclusion of these other possible causes. Patients typically present in mid-adulthood with dyspnoea, cough and often constitutional symptoms including fever and fatigue. The disease has a female predominance, and more than 50% of patients have never smoked. Physical exam features mild hypoxaemia and inspiratory rales. Pulmonary function tests demonstrate restriction and a low diffusing capacity for carbon monoxide. High-resolution computed tomography abnormalities include predominantly lower lobe subpleural reticular changes, traction bronchiectasis and ground-glass opacities; honeycombing is rarely seen. An evaluation of the underlying pathology is necessary for a firm diagnosis. Histologically, alveolar and interstitial mononuclear cell inflammation and fibrosis are seen in a temporally uniform pattern with preserved underlying alveolar architecture. NSIP must be differentiated from other parenchymal lung diseases including idiopathic pulmonary fibrosis and hypersensitivity pneumonitis. A thorough exposure history and assessment for underlying connective tissue diseases are highly important, as positive findings in these categories would likely denote a case of secondary NSIP. A multi-disciplinary discussion that includes pulmonologist(s), radiologist(s) and pathologist(s) assists in reaching a consensus diagnosis and improves diagnostic accuracy. Treatment of idiopathic NSIP, although not well proven, is generally instituted in the form of immunosuppression. Prognosis is favourable compared with idiopathic pulmonary fibrosis, although the diagnosis still carries an attributable mortality. Herein we will summarize the clinical characteristics and management of idiopathic NSIP.

A 30 years old non diabetic female presented with bilateral breast lumps with history of rhinitis off & on and peripheral eosinophilia. Mammography was suspicious while ultrasonography was diagnostic of bilateral mastitis. Aspiration cytology exhibited inflammatory lesion rich in eosinophils. Histopathology revealed the diagnosis of eosinophilic mastitis. Eosinophilic infiltration of the breast is a rare manifestation of tissue involvement in peripheral eosinophilia and bilateralism is even rarer.

    Williams and Mikhael (1971) described idiopathic urethritis (IU) as a self-limiting condition that affects boys aged 5-15 years, with symptoms of urethrorrhagia, dysuria and haematuria. However, a proportion of boys will remain symptomatic for several years, and may develop urethral stricture (Poch et al., 2007; Palagiri et al., 2003). There is no universally effective treatment for IU, although various strategies have been employed. To review the presentation and long-term outcomes of boys with IU, and present the efficacy of management strategies that have been utilised. A retrospective review was performed of all boys with IU. It was based on clinical and cystoscopic findings for presentation, medical history, management and clinical progress. Fifty-four boys were included, with a median age of 11 years (range 5-15 years) at presentation. The median duration of symptoms was 18 months (range 2-132 months). The median follow-up was 18.5 months (range 1-120 months). Seven (13.0%) boys had early urethral stricture at initial cystourethroscopy, and one (1.9%) developed stricture during follow-up. Thirty-six boys (66.7%) had previous circumcision and four (7.4%) had meatal stenosis. Eight (14.8%) had previous hypospadias repair. Whilst 50% of boys with IU do not require any specific treatment, those with severe/unremitting symptoms may benefit from a trial of urethral steroids or short-term urethral catheterisation. The mechanisms of benefit from these modalities are unclear and they require further evaluation. Copyright © 2015 Journal of Pediatric Urology Company. Published by Elsevier Ltd.

    2017-04-01

    Scoliosis is a common medical problem, with an incidence of between 0.47% and 5.2% in the general population globally. Adolescent idiopathic scoliosis (AIS) accounts for nearly 80% of all scoliosis. Young people with AIS often experience negative social consequences in association with their condition. Without proper and timely treatment, the potential resulting disabilities range from trunk deformity, pain, and neurological complications to compromised cardiopulmonary function, all of which may cause lifelong suffering. Scoliosis may be treated either conservatively or surgically, based on the severity of the disease. Bracing is the most widely adopted method of conservative treatment. However, the main goal of bracing is to inhibit the progression of the spinal curvature rather than to cure scoliosis. The clinical effectiveness of bracing in Taiwan has often been underutilized as a result of financial or other factors such as the availability of the treatment. The purpose of the present review is to clarify the effectiveness of bracing for AIS by elucidating the pathophysiology of scoliosis and examining the recent clinical evidence. The importance of preventative care and the unique contribution of nursing care to treatment has to date been under-recognized. The positive support that nurses provide to the families of the patients during the early phases of treatment as well as to the patients themselves, including helping them exercise appropriately and wear the brace correctly, is an essential component of effective treatment. Learning how to work with and to adapt to the brace being part of the body is an important part of the treatment as well as a way to avoid pain. Nurses are in an ideal position to facilitate this learning process and, overall, to provide health education.

    To delineate the factors contributing to overdiagnosis of idiopathic intracranial hypertension (IIH) among patients seen in one neuro-ophthalmology service at a tertiary center. We retrospectively reviewed new patients referred with a working diagnosis of IIH over 8 months. The Diagnosis Error Evaluation and Research taxonomy tool was applied to cases referred with a diagnosis of IIH and a discrepant final diagnosis. Of 1,249 patients, 165 (13.2%) were referred either with a preexisting diagnosis of IIH or to rule out IIH. Of the 86/165 patients (52.1%) with a preexisting diagnosis of IIH, 34/86 (39.5%) did not have IIH. The most common diagnostic error was inaccurate ophthalmoscopic examination in headache patients. Of 34 patients misdiagnosed as having IIH, 27 (27/34 [79.4%]; 27/86 [31.4%]) had at least one lumbar puncture, 29 (29/34 [85.3%]; 29/86 [33.7%]) had a brain MRI, and 8 (8/34 [23.5%]; 8/86 [9.3%]) had a magnetic resonance/CT venogram. Twenty-six had received medical treatment, 1 had a lumbar drain, and 4 were referred for surgery. In 8 patients (8/34 [23.5%]; 8/86 [9.3%]), an alternative diagnosis requiring further evaluation was identified. Diagnostic errors resulted in overdiagnosis of IIH in 39.5% of patients referred for presumed IIH, and prompted unnecessary tests, invasive procedures, and missed diagnoses. The most common errors were inaccurate ophthalmoscopic examination in headache patients and thinking biases, reinforcing the need for rapid access to specialists with experience in diagnosing optic nerve disorders. Indeed, the high prevalence of primary benign headaches and obesity in young women often leads to costly and invasive evaluations for presumed IIH. © 2015 American Academy of Neurology.

    Sickle cell disease is a common inherited autosomal disease that is characterised by abnormally shaped (sickle-shaped) red blood cells (RBCs). It can involve virtually any organ system. The clinical manifestations of sickle cell disease vary and are classified as vaso-occlusion, chronic anaemia and infection. The imaging appearances of central nervous system and musculoskeletal involvement by sickle cell disease have been well documented; however, involvement of the head and neck region is often unreported, although it is not uncommon. In the head and neck, sickle cell disease can involve the inner ears, orbits, paranasal sinuses, bones, lymph nodes and vessels. This paper describes a case of idiopathic facial swelling associated with sickle cell disease in a young patient.

    Since the introduction of levodopa therapy for idiopathic Parkinson's disease over 20 years ago, there has been an awakening of research interest in this chronic neuro-degenerative disorder. This paper describes current understanding of the role of genetic and environmental factors in the aetiology of idiopathic Parkinson's disease and problems associated with both diagnosis and management. It briefly outlines both pharmacological and non-pharmacological options for treatment. Despite an increasing armoury of available treatments, the optimum management for this condition remains controversial. PMID:7619574

    Although occipital neuralgia is usually caused by degenerative arthropathy, nearly 20 other aetiologies may lead to this condition. We present the first case report of hypertrophic pachymeningitis revealed by isolated occipital neuralgia. Idiopathic hypertrophic pachymeningitis is a plausible cause of occipital neuralgia and may present without cranial-nerve palsy. There is no consensus on the treatment for idiopathic hypertrophic pachymeningitis, but the usual approach is to start corticotherapy and then to add immunosuppressants. When occipital neuralgia is not clinically isolated or when a first-line treatment fails, another disease diagnosis should be considered. However, the cost effectiveness of extended investigations needs to be considered.

    Eighteen subfertile men, with idiopathic normogonadotropic oligozoospermia were treated with an antiestrogenic compound, tamoxifen (Nolvadex), at the dose of 20 mg/day for four months. Hormonal parameters (LH, FSH, Testosterone, Prolactin) were evaluated before treatment and after 45 and 90 days of therapy. Serum LH, FSH and Testosterone increased significantly after 45 days of tamoxifen treatment. Seminal analyses, performed before and after three months of therapy showed improvements in sperm motility and in sperm density. By our clinical findings, tamoxifen can be considered a useful approach for an empiric treatment of idiopathic oligozoospermia.

We are reporting here an autopsy case of idiopathic giant cell myocarditis with no symptoms in a 27-year old -worker who died suddenly. The purpose of this report was to emphasize that idiopathic giant cell myocarditis was a rare disease and that it could exist in the absence of any symptomatic heart disease. PMID:23205365

  7. Is pirfenidone effective for idiopathic pulmonary fibrosis?

    PubMed

    2017-01-17

    Idiopathic pulmonary fibrosis has an ominous prognosis and there are virtually no effective therapies. It has been suggested that pirfenidone, an antifibrotic agent, could change its course. Searching in Epistemonikos database, which is maintained by screening multiple databases, we identified 13 systematic reviews comprising nine trials addressing the question of this article, seven of which are randomized and whose results were analyzed in this summary. We combined the evidence using meta-analysis and generated a summary of findings following the GRADE approach. We concluded pirfenidone decreases disease progression and mortality in idiopathic pulmonary fibrosis. Although it is associated with frequent gastrointestinal and cutaneous adverse effects, these are generally not severe.

  8. Osteoarthritis, osteoarthrosis, and idiopathic condylar resorption.

    PubMed

    Mercuri, Louis G

    2008-05-01

    The term "osteoarthritis" has classically been defined as a low-inflammatory arthritic condition. The term "osteoarthrosis," a synonym for osteoarthritis in the medical orthopedic literature, has recently come to be identified in the dental/temporomandibular joint (TMJ) disorders literature with any noninflammatory arthritic condition that results in similar degenerative changes as in osteoarthritis. The term "idiopathic condylar resorption," also known as "progressive condylar resorption," is described as a dysfunctional remodeling of the TMJ manifested by morphologic change, decreased ramal height, progressive mandibular retrusion in the adult, or decreased mandibular growth in the juvenile. This article discusses the diagnosis and management of osteoarthritic TMJ disorders and idiopathic condylar resorption.

  9. A Case of Idiopathic Thyrotropin (TSH) Deficiency

    The first case of idiopathic thyrotropin (TSH) deficiency in an old woman with thyroid functioning adenoma was reported. She got subtotal thyroidectomy before about four years of her admission to our hospital because of fatigability, puffy face and leg edema. At that time, she had low TSH and free T4 levels despite replacement therapy with desiccated thyroid. No response of only serum TSH after adminstration of combined stimulant containing TRH and repeated TRH suggested the failure of TSH secretion. CT MRI did not show any abnormality. These results indicated that her hypothyroidism was due to acquired idiopathic TSH deficiency. PMID:9159047

    The interactions between the bilaterally distributed components of the circadin system that controls the locomotor activity rhythm of the cockroach Leucophaea maderae were investigated in a series of surgical lesion experiments. Complete excision of one optic lobe (either right or left) or its surgical isolation from the central nervous system had no effect on the animals' ability to free-run in constant darkness nor was there any indication, as judged by postoperative pi values of any difference between left and right lobe pacemakers. However, these surgical procedures consistently resulted in a significant increase in tau over preoperative value while optic nerve section had no effect on tau. The propostion is developed that the left and right pacemakers in the two optic lobes are mutally coupled and that the compound pacemaker's period is shorter than either of its constituent pacemakers. It was also found that the integrity of either compound eye is sufficient to assure entrainment of both left and right pacemakers. Images PMID:265571

  11. Bilateral symmetry in crayfish behavioral reactions.

    2008-01-01

    The crayfish, Procambarus cubensis, placed in the central area of a plus-maze preferred to go forward in about 50% of trials; they chose the right or left arm in 20.7 and 18.9% of the trials, respectively. In a T-maze, the difference between right and left directions was also insignificant. When exploring a plus-maze, the crayfish turned to 180 degrees at the end of the arms, then turned to 90 degrees going to the next arm. The mean difference between the right and left U-turns, and the right and left turns was insignificant though some animals demonstrated a left or right preference. There was a strong correlation between the direction of U-turns and following turns ensuring the clockwise or anti-clockwise movements of the crayfish. Also we examined a possible preference of the right or left claw in the feeding behavior of the crayfish. The crayfish caught a small bloodworm given from above equally with the right or left claw. The crayfish conditioned to take a bloodworm with a claw did not demonstrate any stable preference of left or right claw in the course of the experiments. The question of bilateral asymmetries within the decapod crustaceans is discussed.

  12. Bilateral Neck of Femur Fractures in a Bilateral Below-Knee Amputee: A Unique Case

    2016-01-01

    According to the National Hip Fracture Database, over 64,000 patients were admitted with a hip fracture across England, Wales, and Northern Ireland in 2013, but very few are bilateral, and there are no current cases in the literature of bilateral neck of femur fractures in a patient with bilateral below-knee amputations. We present a case of a 69-year-old bilateral below-knee amputee male admitted to the emergency department with bilateral hip pain and radiological evidence of bilateral displaced neck of femur fractures. The patient subsequently underwent synchronous bilateral total hip replacements under general anaesthetic and an epidural and then went on to make a full recovery. He was discharged 27 days after arrival in hospital. Outpatient follow-up at 3 months has shown that the patient has returned to a similar level of preinjury function and is still able to carry out his daily activities with walking aids and bilateral leg prostheses.

  13. Bilateral adrenalectomy for Cushing's disease.

    PubMed

    Katznelson, Laurence

    2015-04-01

    Review the indications, outcomes, and consequences of bilateral adrenalectomy (BLA) in patients with Cushing's disease. A literature review was performed. The primary therapy for Cushing's disease is surgery, with medical therapy and radiation therapy relegated to an adjuvant role. BLA is indicated in cases of persistent disease following pituitary surgery or in situations where rapid normalization of hypercortisolism is required. When performed via the laparoscopic approach, BLA is associated with a significantly reduced morbidity compared to the traditional, open approach. Following BLA, patients are at risk for adrenal crisis and the concern of Nelson's syndrome. However, BLA leads to a rapid resolution of the signs and symptoms of CS and leads to an improved long-term quality of life. BLA should be considered in the treatment algorithm for patients with persistent CD after failed pituitary surgery, especially in patients who have severe consequences of hypercortisolism or desire pregnancy.

  14. Bilateral fitting subtracting confocal microscopy.

    2016-12-20

    This paper proposes a bilateral fitting subtracting confocal microscopy (BFSCM) based on the optical arrangement of conventional confocal microscopy (CM). BFSCM first uses the data in both sides of a confocal axial response curve, which are very sensitive to the axial position of the sample, for respective linear fitting to obtain two fitting straight lines, and then obtains a difference confocal line by subtraction of the two fitting lines. Finally, it calculates the zero position of the difference confocal line to precisely capture the focus position of the confocal system, and thereby achieving a high-precision measurement of the 3D structure of the sample. The theoretical analyses and experiments indicate that BFSCM can improve the axial resolution, and has anti-interference capability and focusing ability with bipolar absolute zero point tracking, while it does not change the structure and lateral resolution of CM. BFSCM provides a novel method for the improvement of CM axial resolution.

    Iatrogenic Cushing syndrome induced by oral and parenteral corticosteroid administration is a well-known complication, and necessary precautions have to be taken. Cushing syndrome, however, following treatment with glucocorticoid-containing eye drops is a very rare complication. To the best of our knowledge, there have been only four reported cases in the literature. Herein, we present an infant boy who developed Cushing syndrome after receiving dexamethasone-containing eye drops after bilateral cataract extraction to prevent postoperative inflammatory complications. At the age of 5 months, after approx. 3 months of dexamethasone therapy, the patient presented with cushingoid facies, nephrocalcinosis and failure to grow. Iatrogenic Cushing syndrome was diagnosed and dexamethasone-containing eye drops were reduced and eventually stopped. Follow-up examinations revealed catch-up growth. Ocularly administered corticosteroids may have substantial systemic side effects in infants.

    2012-01-01

    Intravascular migration of bullets and other foreign bodies is a rare but known complication of penetrating trauma. Missile embolization can represent a diagnostic challenge because it may present in various and unexpected ways. We present the case of a 54-year-old female who sustained shotgun pellet emboli to the pulmonary arteries following a left upper extremity gunshot wound and related vascular surgery. The case illustrates bilateral embolization, and the embolic events occurred following surgery. Embolization should be considered in evaluating patients with gunshot wounds, particularly if there are anomalous symptoms or the projectile is not found in the original, or expected, location. Close attention to the location of the foreign bodies on serial radiographs may reveal the diagnosis of intravascular embolization. PMID:22690290

    Temporomandibular joint (TMJ) involvement is common but usually delayed in patients with juvenile idiopathic arthritis (JIA). We describe the case of a JIA patient with bilateral TMJ involvement, mandibular retrognathia, bone erosion, and severely restricted mouth opening. The use of cone beam computed tomography and a 3D diagnostic protocol in young patients with JIA provides reliable, accurate and precise quantitative data and images of the condylar structures and their dimensional relationships. Analgesics and conventional disease modifying antirheumatic drugs were ineffective, but interdisciplinary treatment with etanercept and a Herbst functional appliance improved functional TMJ movement and bone resorption.

    PubMed

    2017-01-01

    Background Simultaneously developed bilateral primary spontaneous pneumothorax (BPSP) is an indication for thoracic surgery of both sides. Recently, we have reported a new technique for BPSP, which is ipsilateral apicoposterior transmediastinal (TM) bullectomy of both sides using video-assisted thoracoscopic surgery (VATS), and we compared this TM VATS with bilateral sequential (BS) VATS for BPSP. Materials and Methods From June 2003 to May 2014, 11 and 14 patients were performed VATS TM and BS bullectomy for BPSP, respectively. We reviewed the medical records and compared the clinical data between the two groups. For TM group, we first performed the right VATS bullectomy and approached through the apicoposterior mediastinal region for contralateral VATS. In the other group, conventional BS VATS bullectomy was performed in the lateral decubitus position change. Results The mean follow-up was 62.0 ± 32.6 months. No mortality and major complications were observed. The operative time (68.18 ± 24.93 vs. 96.07 ± 37.73, p = 0.046), duration of left pleural drainage (1.00 ± 0.45 vs. 3.21 ± 1.37, p = 0.000), and length of hospital stay (3.82 ± 1.54 vs. 4.93 ± 1.07, p = 0.044) were significantly shorter in the TM group than in the BS group. No significant differences were seen in duration of general anesthesia, total number of wedge resections and endostaplers used in both lungs, duration of right drainage, and postoperative recurrence. Conclusion The TM VATS approach may be a safe and feasible modality for BPSP. It may decrease the operative time, patients inconvenience such as bilateral multiple wounds and longstanding placement of chest tubes, and decrease the hospital stay compared with the BS VATS approach.

    We evaluated relationships between diffusion tensor imaging (DTI) findings and clinical profiles in idiopathic normal-pressure hydrocephalus (INPH) patients, along with differences in DTI parameters between cerebrospinal fluid tap test (CSFTT) responders and non-responders. Fifty-four INPH patients constituted the final group for analysis. Fractional anisotropy (FA), axial diffusivity, radial diffusivity, and mean diffusivity were assessed using atlas-based tract-mapping methods on 20 different fiber tracts. Uncorrected results revealed that CSFTT non-responders, when compared to responders, exhibited lower FA in the left anterior thalamic radiation (ATR), left cingulum-hippocampus (CgH), and left inferior fronto-occipital fasciculus (IFO) and higher axial diffusivity, radial diffusivity, and mean diffusivity in the left CgH and left inferior longitudinal fasciculus (ILF). FA values in the ATR (bilateral), corticospinal tract (right), IFO (bilateral), and ILF (bilateral) were negatively correlated with Unified Parkinson's Disease Rating Scale motor scores. In the right CgH, FA values showed significant positive correlations with Korean-Mini Mental State Examination scores and negative correlations with Clinical Dementia Rating Scale scores. Our findings may suggest a possibility for considering microstructural changes of white matter in patients with ventriculomegaly as potential imaging markers for the prediction of CSFTT responders. Unique patterns of white matter microstructural changes, as measured using DTI, might underlie impairments in distinct symptom domains in patients with INPH. Copyright © 2016 Elsevier B.V.

    Capgras syndrome is a delusional misidentification syndrome (DMS) which can be seen in neurodegenerative diseases such as Lewy body dementia and, to a lesser extent, in Parkinson's disease (PD). Here, we report the case of a 78-year-old man with a history of idiopathic PD who developed Capgras syndrome following bilateral subthalamic nucleus deep brain stimulation (DBS) implantation. As the risk of DMS has been related to deficits in executive, memory, and visuospatial function preoperatively, this case highlights the importance of continuing to improve patient selection for DBS surgery. Capgras syndrome is a rare potential complication of DBS surgery in PD patients with preexisting cognitive decline. PMID:26078747

    2016-12-01

    Central diabetes insipidus (CDI), characterized by polyuria and polydipsia, is caused by deficiency of arginine vasopressin (AVP), an antidiuretic hormone which acts on V2 receptors in kidney to promote reabsorption of free water. CDI is classified into three subtypes; idiopathic, secondary and familial. A previous study suggests that infundibulo-neurohypophysitis might be an underlying cause of idiopathic CDI. Among secondary CDI, the tumors in the central nervous system such as craniopharyngioma and germ cell tumors are the most frequent causes. Familial CDI is inherited mostly in an autosomal dominant mode, and the number of causal mutations in the AVP gene locus reported so far exceeds 80. CDI is treated with desmopressin, an analogue of vasopressin, and the tablet is preferred to the nasal form because it is easier to administer. It is also shown that the oral disintegrating tablet formula increases QOL and decreases the incidence of hyponatremia in CDI patients. In some CDI patients, the osmoreceptors in the hypothalamus do not function and patients do not sense thirst. These adipsic CDI patients are treated with desmopressin and adjusting the amount of daily water intake based on body weight measurement; but controlling the water balance is extremely difficult, and morbidity and mortality are shown to be high in these patients.

    Many years of bracing represent a burden to the patients. Early weaning may be the result of poor compliance, but may also be planned in patients with a long expected treatment time and a reduced stable primary curve during bracing. The aim of the present cohort study was to compare curve size, health related quality of life and surgical rates at long-term follow-up after ordinary bracing, planned and unplanned early weaning. Three hundred eighty-one patients (353 girls/28 boys) with late-onset juvenile (n = 30) and adolescent (n = 351) idiopathic scoliosis and a mean primary major curve of 33.1 (range 20-57)° were treated with Boston brace and followed prospectively. Ordinary brace treatment was completed in 290 (76 %) patients, planned early weaning at bone age <14 years in 59 (16 %), and unplanned early weaning in 32 (8 %), while 14 (5 %), 1 (2 %), and 12 (38 %) had surgery, respectively. Forty-eight (81 %) of the patients had a primary curve ≤ 25° at planned early weaning. Six-teen (27 %) of those who had planned early weaning, resumed bracing after a mean time of 2.0 years. The mean curve size at long-term follow-up in average 23.4 years after weaning, was smaller (p < 0.001) in patients with planned early weaning (25.1°) compared with ordinary bracing (34.0°) and unplanned early weaning (34.8°). Patient satisfaction and self-image at long-term was better in the planned early weaning group (p < 0.05), but differences were small. The benefit of planned early weaning was the shortened bracing time and good clinical results. This procedure may be attempted if curve reduction is stable over time and the primary curve is 25° or less in patients with several years of expected bracing. The patients should be monitored carefully and regularly at 4-6 months intervals until maturity, and a new brace should be prepared if the curve increases significantly.

    The features of idiopathic hypersomnia are not well defined. We reviewed clinical and laboratory information on 42 subjects with idiopathic hypersomnia and obtained detailed follow-up evaluations on 28 of them. Only 29% of subjects had 'classic' idiopathic hypersomnia with non-imperative sleepiness, long unrefreshing naps, prolonged night-time sleep, difficult awakening with sleep drunkenness and prominent mood disturbances. Thirty-two percent had clinical features similar to narcolepsy, i.e. irresistible sleepiness, short and refreshing naps, few problems with awakening and good response to stimulants, without cataplexy or any indication of abnormal REM (rapid eye movement) sleep. The other 39% had intermediate clinical characteristics. We found no increase in the frequency of the human leucocyte antigens associated with narcolepsy. Overall, response to stimulants was good in three-quarters of the patients and spontaneous improvement of sleepiness occurred in one-quarter. Possible aetiologies identified in 10 patients included viral illness, head trauma and primary mood disorder. Idiopathic hypersomnia is a rare syndrome in which clinical heterogeneity suggests a variable or multifactoral pathogenesis. Only a minority of cases correspond to classical descriptions. Stimulants are often beneficial and spontaneous improvement appears to be more common than in narcolepsy.

    Idiopathic arterial calcification of infancy is a rare autosomal recessive disease, characterized by deposition of calcium along the internal elastic membrane of arteries, accompanied by fibrous thickening of the intima which causes luminal narrowing. Here we are reporting a case of idiopathic arterial calcification of infancy in a Saudi female newborn of non-consanguineous pregnant woman who had polyhydramnios. The newborn baby had severe respiratory distress, systemic hypertension and persistent pulmonary hypertension of newborn. She was admitted to Neonatal Intensive Care Unit, where she was ventilated and proper treatment was provided. Molecular genetic testing was positive for mutations of ectonucleotide pyrophosphatase/phosphodiesterase1 gene which is reported in 80% of cases of Idiopathic arterial calcification of infancy. The baby died at about 5 month of age because of myocardial ischemia and cardiorespiratory arrest. Idiopathic Arterial Calcification of Infancy should be considered in any newborn who presented with persistent pulmonary hypertension of newborn, severe systemic hypertension and echogenic vessels on any radiological study. Calcifications of large and medium-sized arteries are important diagnostic finding.

    Idiopathic arterial calcification of infancy is a rare autosomal recessive disease, characterized by deposition of calcium along the internal elastic membrane of arteries, accompanied by fibrous thickening of the intima which causes luminal narrowing. Here we are reporting a case of idiopathic arterial calcification of infancy in a Saudi female newborn of non-consanguineous pregnant woman who had polyhydramnios. The newborn baby had severe respiratory distress, systemic hypertension and persistent pulmonary hypertension of newborn. She was admitted to Neonatal Intensive Care Unit, where she was ventilated and proper treatment was provided. Molecular genetic testing was positive for mutations of ectonucleotide pyrophosphatase/phosphodiesterase1 gene which is reported in 80% of cases of Idiopathic arterial calcification of infancy. The baby died at about 5 month of age because of myocardial ischemia and cardiorespiratory arrest. Idiopathic Arterial Calcification of Infancy should be considered in any newborn who presented with persistent pulmonary hypertension of newborn, severe systemic hypertension and echogenic vessels on any radiological study. Calcifications of large and medium-sized arteries are important diagnostic finding. PMID:27252793

    A 61-year-old woman attended the breast clinic with unresolving mastitis and an associated mass, following failed treatment with antibiotics. Triple assessment confirmed idiopathic granulomatous mastitis. Unresponsive to further conservative management and steroid therapy, she underwent surgical excision and made uneventful recovery. No evidence of recurrence was detected at 18 months follow-up.

    Peripheral neuropathy is a common problem encountered by neurologists and primary care physicians. While there are many causes for peripheral neuropathy, none can be identified in a large percentage of patients ("idiopathic neuropathy"). Despite its high prevalence, idiopathic neuropathy is poorly studied and understood. There is evolving evidence that impaired glucose tolerance (prediabetes) is associated with idiopathic neuropathy. Preliminary data from a multicenter study of diet and exercise in prediabetes (the Impaired Glucose Tolerance Neuropathy Study) suggests a diet and exercise counseling regimen based on the Diabetes Prevention Program results in improved metabolic measures and small fiber function. Prediabetes is part of the Metabolic Syndrome, which also includes hypertension, hyperlipidemia and obesity. Individual aspects of the Metabolic Syndrome influence risk and progression of diabetic neuropathy and may play a causative role in neuropathy both for those with prediabetes, and those with otherwise idiopathic neuropathy. Thus, a multifactorial treatment approach to individual components of Metabolic Syndrome may slow prediabetic neuropathy progression or result in improvement.

    2002-11-01

    Antidisialosyl antibodies were found in two out of 13 patients with chronic idiopathic ataxic neuropathy (CIAN) and not in 32 patients with different sensory neuropathies of known cause. This finding confirms the association of antidisialosyl antibodies and CIAN regardless of the absence of the M band. These antibodies may have pathogenic relevance; however, larger series are needed to establish their clinical significance.

    Purpose Despite its high prevalence, the etiology underlying idiopathic scoliosis remains unclear. Although initial scrutiny has focused on genetic, biochemical, biomechanical, nutritional and congenital causes, there is growing evidence that aberrations in the vestibular system may play a role in the etiology of scoliosis. In this article, we discuss putative mechanisms for adolescent idiopathic scoliosis and review the current evidence supporting a role for the vestibular system in adolescent idiopathic scoliosis. Methods A comprehensive search of the English literature was performed using PubMed (http://www.ncbi.nlm.nih.gov/pubmed). Research articles studying interactions between adolescent idiopathic scoliosis and the vestibular system were selected and evaluated for inclusion in a literature review. Results Eighteen manuscripts of level 3-4 clinical evidence to support an association between AIS and dysfunction of the vestibular system. These studies include data from physiologic and morphologic studies in humans. Clinical data are supported by animal model studies to suggest a causative link between the vestibular system and AIS. Conclusions Clinical data and a limited number of animal model studies suggest a causative role of the vestibular system in AIS, although this association has not been reproduced in all studies.

    Sialosis is observed in relation to diabetes, alcoholism, and malnutrition. An assumed relation between gout and sialosis is probably based on confusion that originated from the therapeutic use of phenylbutazone for gout and the sialadenitis that the medication caused. This report describes a case of sialosis in a patient with a longstanding history of gout that was idiopathic in origin.

    Background Lesions in the Guillain–Mollaret triangle or dentate-rubro-olivary pathway may lead to hypertrophic olivary degeneration (HOD), a secondary trans-synaptic degeneration of the inferior olivary nucleus. HOD is usually associated with palatal tremor and rarely with Holmes tremor. Bilateral HOD is a very unusual condition and very few cases are reported. Case Report We report here two cases of bilateral HOD after two different vascular lesions located at the decussation of superior cerebellar peduncles, thus impairing both central tegmental tracts and interrupting bilaterally the dentate-rubral-olivary pathway. Interestingly, both developed bilateral Holmes tremor but not palatal tremor. Discussion Lesions in some of the components in the Guillain–Mollaret triangle may develop Holmes tremor with HOD and without palatal tremor. Magnetic resonance imaging is an invaluable tool in these cases. Better understanding of the pathways in this loop is needed. PMID:27536461

    Bilateral medial medullary infarction (MMI) is a rare type of stroke with poor outcomes. Inferior olivary nucleus hypertrophy results from a pathologic lesion in the Guillain-Mollaret triangle. The relationship between inferior olivary nucleus hypertrophy and the medullary lesion is obscure. To the best of our knowledge, only 1 autopsy case with unilateral medial medullary infarction that was associated with ipsilateral inferior olivary nucleus hypertrophy has been reported. We describe a rare case with acute infarction in the bilateral medial medulla oblongata accompanied by subacute bilateral inferior olivary nucleus hypertrophy and panmedullary edema. The hypertrophy appeared to have been caused by local ischemic damage to the termination of the central tegmental tract at the bilateral inferior olivary nucleus.

    Xanthogranulomatous orchitis (XGO) is a rare chronic inflammatory process characterized by destruction of tissue that is replaced by an outstanding cellular infiltrate of lipid-laden macrophages. To date, 20 cases of this process have been reported previously. We present herein the case of a 55-year-old man who had sustained complete tetraplegia at C-6 level and neuropathic bladder for 21 years. After repeated episodes of urinary tract infection, the patient developed a bilateral XGO and a right xanthogranulomatous epididymitis (XGE) that were treated with bilateral orchiepididymectomy. To our knowledge, a bilateral XGO has not yet been reported. Repeated episodes of high-pressure urinary reflux along the vas deferens during dyssynergic voiding possibly led to retrograde extension from the urinary tract by common urinary pathogens and development of bilateral XGO and right XGE. Since tissue destruction is a feature of this process, curative treatment required antibiotic therapy followed by bilateral excision of testes and epididymes.

    Childhood cystic partially differentiated nephroblastoma (CPDN) is an uncommon renal neoplasm. Bilateral CPDN or CPDN co-existing with a cystic nephroma/Wilms tumour is extremely rare. Treatment of CPDN is by complete surgical excision. Although local recurrences are uncommon, distant metastases have not been described. We present a case of bilateral CPDN that, after complete excision, recurred as bilateral cystic Wilms tumour. To the best of our knowledge, this is the first reported case in the literature where a bilateral CPDN has recurred as bilateral Wilms tumour.

    Simultaneous bilateral facial paralisis (SBFP) occurs in 0.3-2% of all facial paralisis. We report a case of SBFP in association with Lyme disease. A review of literature about SBFP is made, studing specially the one caused by Borrelia burgdorferi. We present a diagnostic guideline of SBFP. Suspect diagnosis of Lyme disease is based on clinical and epidemiological criteria. Culture isolation of this bacteria is difficult, therefore serologic testing is required. Neuroborreliosis treatment is intravenous Ceftriaxone or Cefotaxime. Oral Doxycycline is useful in the treatment of neuritis without central nervous system involvement.

    Supernumerary teeth are considered as one of the most significant dental anomalies during the primary and early mixed dentition stages. They are of great concern to the dentists and parents because of the eruption, occlusal, and esthetic problems they can cause. Supernumerary teeth occur more frequently in the permanent dentition but rarely in primary dentition and more often seen in males. A supernumerary tooth in the primary dentition can cause ectopic or delayed eruption of permanent central incisors which will further alter occlusion and may compromise esthetics and formation of dentigerous cysts. Here we discuss a case of bilateral supernumerary teeth in deciduous dentition in a female child.

    ABSTRACT Leber hereditary optic neuropathy (LHON) causes visual loss, predominantly in healthy young men. We recently examined a patient who previously had bilateral macular holes and subsequently developed LHON at 74 years of age. Although his central scotomas were initially attributed to the macular holes, his visual acuity declined following an initial improvement after operative closure of the macular holes; thus, other diagnoses, including LHON, were considered. Furthermore, macular optical coherence tomography (OCT) images remained unchanged in this time. A mitochondrial genetic analysis identified a 11778G→A mutation. From this case, we propose that LHON remains in the differential diagnosis even in older patients, as has previously been reported. PMID:27335507

    The purpose of this study was to determine if simultaneous bilateral carpal tunnel release (CTR) is a cost-effective strategy compared with bilateral staged CTR for the treatment of bilateral carpal tunnel syndrome. A decision analytic model was created to compare the cost effectiveness of three strategies (ie, bilateral simultaneous CTR, bilateral staged CTR, and no treatment). Direct medical costs were estimated from 2013 Medicare reimbursement rates and wholesale drug costs in US dollars. Indirect costs were derived from consecutive patients undergoing unilateral or simultaneous bilateral CTR at our institution and from national average wages for 2013. Health state utility values were derived from a general population of volunteers using the Short Form-6 dimensions (SF-6D) health questionnaire. Both surgical strategies were cost effective compared with the no-treatment strategy. Bilateral simultaneous CTR had lower total costs and higher total effectiveness than bilateral staged CTR, and had an incremental cost-effectiveness ratio of $921 per quality-adjusted life year compared with the no-treatment strategy. The conclusions of the analysis remained unchanged though all sensitivity analyses, displaying robustness against parameter uncertainty. Surgical management is cost effective for the treatment of bilateral carpal tunnel syndrome. Bilateral simultaneous CTR, however, has lower total costs and higher total effectiveness compared with bilateral staged CTR. Economic and Decision Analysis I.

    Purpose To report on corneal ulceration in ocular graft-versus-host disease (GVHD). Methods This was a retrospective, observational case series investigating corneal ulceration and perforation in a cohort of ocular GVHD patients seen between June 2007 and October 2012. Results Four of 243 ocular GVHD patients developed corneal ulcerations attributable to ocular GVHD, and all four cases involved bilateral corneal ulceration. The median length of time from the diagnosis of ocular GVHD to the diagnosis of the first corneal ulceration was 317 days (range 168–434). The median length of time between the diagnosis of corneal ulceration in each patient’s first and second eye was 248 days (range 9–645). Outcomes varied from complete resolution with medical treatment to corneal perforation necessitating penetrating keratoplasty. In cases of corneal perforation, the median length of time from the diagnosis of corneal ulceration to perforation was 10 days (range 0–20). Common clinical features included: centrally or paracentrally located ulcerations and perforations, concomitant dry eye, and the use of topical or systemic corticosteroids. Conclusion Frequent follow-up and bilateral monitoring are highly recommended in cases of ocular GVHD-associated stromal thinning, as bilateral involvement or rapid progression to corneal perforation can occur.

    We report a case of bilateral lung transplantation (BLT) after preservation of the donor graft for 16 h 5 min with EP-TU, an extracellular phosphate-buffered lung preservation solution. The recipient was a 26-year-old woman with idiopathic pulmonary arterial hypertension and the graft ischemic time was prolonged significantly because of the time required to induce peripheral veno-arterial extracorporeal membrane oxygenation (V-A ECMO) under local anesthesia, and address the severe intrathoracic and pericardial adhesions from past surgery for partial anomalous pulmonary venous return, with concurrent annular plication of the tricuspid valve. After the operation, ECMO and continuous hemodiafiltration were started preemptively to protect the grafts against excessive edema. Postoperative chest X-ray showed diffuse bilateral infiltrates, which improved within a few days and she was weaned off ECMO on day 9. Successful BLT after a graft ischemic time of over 16 h has rarely been described in clinical lung transplantation.

    There are three main highland areas on Venus: Beta Regio, Ishtar Terra and Aphrodite Terra. The latter is least known and the least mapped, yet existing analyses of Aphrodite Terra based on available Pioneer-Venus orbiter data suggest that it may be the site of extensive rifting. Some of the highest resolution (30 km) PV data (SAR) included most of the western half of Aphrodite Terra. Recent analysis of the SAR data together with Arecibo range-doppler topographic profiling (10 X 100 km horizontal and 10 m vertical resolution) across parts of Aphrodite, further characterized the nature of possible tectonic processes in the equatorial highlands. The existence of distinct topographic and radar morphologic linear discontinuities across the nearly east-west strike of Aphrodite Terra is indicated. Another prominent set of linear features is distinctly parallel to and orthogonal to the ground tracks of the PV spacecraft and are not included because of the possibility that they are artifacts. Study of the northwest trending cross-strike discontinuities (CSD's) and the nature of topographic and morphologic features along their strike suggest the presence of bilateral topographic and morphologic symmetry about the long axis of Aphrodite Terra.

    Simultaneous bilateral inferior petrosal sinus sampling (BIPSS) plays a crucial role in the diagnostic work-up of Cushing’s syndrome. It is the most accurate procedure in the differential diagnosis of hypercortisolism of pituitary or ectopic origin, as compared with clinical, biochemical and imaging analyses, with a sensitivity and specificity of 88–100% and 67–100%, respectively. In the setting of hypercortisolemia, ACTH levels obtained from venous drainage of the pituitary are expected to be higher than the levels of peripheral blood, thus suggesting pituitary ACTH excess as the cause of hypercortisolism. Direct stimulation of the pituitary corticotroph with corticotrophin-releasing hormone enhances the sensitivity of the procedure. The procedure must be undertaken in the presence of hypercortisolemia, which suppresses both the basal and stimulated secretory activity of normal corticotrophic cells: ACTH measured in the sinus is, therefore, the result of the secretory activity of the tumor tissue. The poor accuracy in lateralization of BIPSS (positive predictive value of 50–70%) makes interpetrosal ACTH gradient alone not sufficient for the localization of the tumor. An accurate exploration of the gland is recommended if a tumor is not found in the predicted area. Despite the fact that BIPSS is an invasive procedure, the occurrence of adverse events is extremely rare, particularly if it is performed by experienced operators in referral centres. PMID:27352844

    Mental retardation (MR) is a heterogeneous dysfunction of the central nervous system exhibiting complex phenotypes and has an estimated prevalence of 1-3% in the general population. However, in about 50% of the children diagnosed with any form of intellectual disability or developmental delay the cause goes undetected contributing to idiopathic intellectual disability. A total of 122 children with developmental delay/MR were studied to identify the microscopic and submicroscopic chromosome rearrangements by using the conventional cytogenetics and multiplex ligation dependent probe amplification (MLPA) analysis using SALSA MLPA kits from Microbiology Research Centre Holland [MRC] Holland. All the recruited children were selected for this study, after thorough clinical assessment and metaphases prepared were analyzed by using automated karyotyping system. None was found to have chromosomal abnormality; MLPA analysis was carried out in all subjects and identified in 11 (9%) patients. Karyotype analysis in combination with MLPA assays for submicroscopic micro-deletions may be recommended for children with idiopathic MR.

    Clubfoot is a common structural malformation, occurring in approximately 1/1,000 live births. Previous studies of sociodemographic and pregnancy-related risk factors have been inconsistent, with the exception of the strong male preponderance and association with primiparity. Hypotheses for clubfoot pathogenesis include fetal constraint, Mendelian-inheritance, and vascular disruption, but its etiology remains elusive. We conducted a population-based case-control study of clubfoot in North Carolina, Massachusetts, and New York from 2007 to 2011. Mothers of 677 clubfoot cases and 2,037 non-malformed controls were interviewed within 1 year of delivery about socio-demographic and reproductive factors. Cases and controls were compared for child's sex, maternal age, education, cohabitation status, race/ethnicity, state, gravidity, parity, body mass index (BMI), and these pregnancy-related conditions: oligohydramnios, breech delivery, bicornuate uterus, plural birth, early amniocentesis (<16 weeks), chorionic villous sampling (CVS), and plural gestation with fetal loss. Odds ratios (ORs) and 95% confidence intervals (CIs) were adjusted for state. Cases were more likely to be male (OR: 2.7; 2.2-3.3) and born to primiparous mothers (1.4; 1.2-1.7) and mothers with BMI ≥30 kg/m(2) (1.4; 1.1-1.8). These associations were greatest in isolated and bilateral cases. ORs for the pregnancy-related conditions ranged from 1.3 (breech delivery) to 5.6 (early amniocentesis). Positive associations with high BMI were confined to cases with a marker of fetal constraint (oligohydramnios, breech delivery, bicornuate uterus, plural birth), inheritance (family history in 1st degree relative), or vascular disruption (early amniocentesis, CVS, plural gestation with fetal loss). Pathogenetic factors associated with obesity may be in the causal pathway for clubfoot.

    A 42-year-old woman being treated with 5-fluorouracil for carcinoma of the sigmoid colon developed persistent serpentine supravenous hyperpigmented eruption (PSSHE), bilateral mottling of the palms and diffuse hyperpigmentation of the soles. To the best of our knowledge, such a combination of findings has not been reported earlier. Recognition and knowledge of this side effect are important as the dose of the drug need not be altered nor is there a need to replace the drug on worries about a serious adverse effect. However, changing the peripheral venous route to the central line can be useful in management of PSSHE.

    Ectopic pregnancy is identified with the widely-applied assisted reproductive technology (ART). Bilateral ectopic pregnancy is a rare form of ectopic pregnancy which is difficult to be diagnosed at the pre-operation stage. In this paper, we presented an unusual case of heterochronic bilateral ectopic pregnancy after stimulated intrauterine insemination (IUI), where there has been a delay of 22 d between the diagnoses of the two ectopic pregnancies. Literature was reviewed on the occurrence of bilateral ectopic pregnancy during the past four years in the MEDLINE database. We found 16 cases of bilateral ectopic pregnancy reported since 2008, and analyzed the characteristics of those cases of bilateral ectopic pregnancy. We emphasize that ovulation induction and other ARTs may increase the risk of bilateral ectopic pregnancy. Because of the difficulty in identification of bilateral ectopic pregnancy by ultrasonography, the clinician should be aware that the treatment of one ectopic pregnancy does not preclude the occurrence of a second ectopic pregnancy in the same patient and should pay attention to the intra-operation inspection of both side fallopian tubes in any ectopic pregnancy case.

    This study adopted an inner ear test battery and MR imaging in patients with bilateral sudden sensorineural hearing loss (SSNHL) to investigate their causes, disease extent, and evaluate hearing outcome. From 1995 to 2014, 16 patients with bilateral SSNHL received audiometry, caloric test and MR imaging. Vestibular-evoked myogenic potential (VEMP) test was added to the test battery after 2000. Percentages of abnormal mean hearing level (MHL), cervical VEMP test, ocular VEMP test, and caloric test in patients with bilateral SSNHL were 100% (32/32), 100% (12/12), 100% (4/4), and 81% (26/32), respectively, implying that not only the cochlear part but also the vestibular part was severely affected in both ears. Causes of bilateral SSNHL were neoplasm in 5 patients, stroke in 5, meningitis in 1, and unknown in 5. Post-treatment MHL did not significantly differ from pre-treatment MHL indicating poor hearing outcome. Seven patients (44%) had passed away within 5years after onset, 2 patients were lost, and 7 patients survived. Via MR imaging, causes of bilateral SSNHL were identified for 69% of cases. Both cochlear and vestibular endorgans/afferents were identified to be severely affected bilaterally by the vestibular test battery and resulted in poor hearing outcome. A high mortality rate (44%) indicates that bilateral SSNHL is an ominous sign for a more sinister underlying disease. Copyright © 2016 Elsevier B.V. All rights reserved.

    Exercise therapy is considered an important component of the treatment of arthritis. The efficacy of exercise therapy has been reviewed in adults with rheumatoid arthritis but not in children with juvenile idiopathic arthritis (JIA). To assess the effects of exercise therapy on functional ability, quality of life and aerobic capacity in children with JIA. The Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Systematic Reviews (The Cochrane Library), MEDLINE (January 1966 to April 2007), CINAHL (January 1982 to April 2007), EMBASE (January 1966 to October 2007), PEDro (January 1966 to October 2007), SportDiscus (January 1966 to October 2007), Google Scholar (to October 2007), AMED (Allied and Alternative Medicine) (January 1985 to October 2007), Health Technologies Assessment database (January 1988 to October 2007), ISI Web Science Index to Scientific and Technical Proceedings (January 1966 to October 2007) and the Chartered Society of Physiotherapy website (http://www.cps.uk.org) were searched and references tracked. Randomised controlled trials (RCTs) of exercise treatment in JIA. Potentially relevant references were evaluated and all data were extracted by two review authors working independently. Three out of 16 identified studies met the inclusion criteria, with a total of 212 participants. All the included studies fulfilled at least seven of 10 methodological criteria. The outcome data of the following measures were homogenous and were pooled in a meta-analysis: functional ability (n = 198; WMD -0.07, 95% CI -0.22 to 0.08), quality of life (CHQ-PhS: n = 115; WMD -3.96, 95% CI -8.91 to 1.00) and aerobic capacity (n = 124; WMD 0.04, 95% CI -0.11 to 0.19). The results suggest that the outcome measures all favoured the exercise therapy but none were statistically significant. None of the studies reported negative effects of the exercise therapy. Overall, based on 'silver-level' evidence (www.cochranemsk.org) there was no clinically

    Abstract There are a number of conflicting reports describing the clinical outcomes of using N-acetylcysteine for the treatment of idiopathic pulmonary fibrosis. We have, therefore, performed a meta-analysis to evaluate the efficacy of N-acetylcysteine, compared with control, for the treatment of idiopathic pulmonary fibrosis. Original controlled clinical trials evaluating the efficacy of N-acetylcysteine for the treatment of idiopathic pulmonary fibrosis were included in the analysis. Searches for relevant articles were carried out in July 2014 by 2 independent researchers using PubMed, Embase, Cochrane Central, and Google Scholar. Change in forced vital capacity, change in percentage of predicted vital capacity, change in percentage of predicted carbon monoxide diffusing capacity, changes in 6 minutes walking test distance, rate of adverse events, and rate of death were expressed as outcomes using RevMan 5.0.1. Five trials, with a total of 564 patients, were included in this meta-analysis. The meta-analysis showed that the control group had significant decreases in percentage of predicted vital capacity (standardized mean difference [SMD] = 0.37; 95% confidence interval [CI]: 0.13 to −0.62; P = 0.003) and 6 minutes walking test distance (SMD = 0.25; 95% CI: 0.02–0.48; P = 0.04). There were no statistically significant differences in forced vital capacity (SMD = 0.07; 95% CI: −0.13–0.27; P = 0.52), percentage of predicted carbon monoxide diffusing capacity (SMD = 0.12; 95% CI: −0.06–0.30; P = 0.18), rates of adverse events (odd ratio = 4.50; 95% CI: 0.19–106.41; P = 0.35), or death rates (odd ratio = 1.79; 95% CI: 0.3–5.12; P = 0.28) between the N-acetylcysteine group and the control group. N-Acetylcysteine was found to have a significant effect only on decreases in percentage of predicted vital capacity and 6 minutes walking test distance. N-acetylcysteine showed no beneficial effect on changes

    The successive editions of the International Classification of Sleep Disorders (ICSD) reflect the evolution of the concepts of various sleep disorders. This is particularly the case for central disorders of hypersomnolence, with continuous changes in terminology and divisions of narcolepsy, idiopathic hypersomnia, and recurrent hypersomnia. According to the ICSD 2nd Edition (ICSD-2), narcolepsy with cataplexy (NwithC), narcolepsy without cataplexy (Nw/oC), idiopathic hypersomnia with long sleep time (IHwithLST), and idiopathic hypersomnia without long sleep time (IHw/oLST) are four, well-defined hypersomnias of central origin. However, in the absence of biological markers, doubts have been raised as to the relevance of a division of idiopathic hypersomnia into two forms, and it is not yet clear whether Nw/oC and IHw/oLST are two distinct entities. With this in mind, it was decided to empirically review the ICSD-2 classification by using a hierarchical cluster analysis to see whether this division has some relevance, even though the terms "with long sleep time" and "without long sleep time" are inappropriate. The cluster analysis differentiated three main clusters: Cluster 1, "combined monosymptomatic hypersomnia/narcolepsy type 2" (people initially diagnosed with IHw/oLST and Nw/oC); Cluster 2 "polysymptomatic hypersomnia" (people initially diagnosed with IHwithLST); and Cluster 3, narcolepsy type 1 (people initially diagnosed with NwithC). Cluster analysis confirmed that narcolepsy type 1 and polysymptomatic hypersomnia are independent sleep disorders. People who were initially diagnosed with Nw/oC and IHw/oLST formed a single cluster, referred to as "combined monosymptomatic hypersomnia/narcolepsy type 2." Copyright © 2014 Elsevier B.V.

    A 5-year-old male presented with bilateral poor vision, esotropia and a previous diagnosis of cataract since he was 1 year old. The physical examination revealed bilateral posterior paracentric capsule opacification, vitreous cavity with a permeable pulsatile blood filled hyaloid artery in both eyes. He was kept under observation. Persistent hyaloid artery is an uncommon faulty primary vitreous regression, often unilateral (although it may be bilateral) and sporadic, associated with microphthalmos. It may be complicated with glaucoma and phthisis bulbi. Vitrectomy plus lensectomy or simple observation are the accepted treatment options. Copyright © 2012 Sociedad Española de Oftalmología.

    The sternocleidomastoid muscle shows a wide range of variations including supernumerary muscular heads. We found a rare variation in the sternocleidomastoid muscle with bilateral supernumerary heads in a 67-year-old Korean male cadaver. Bilateral four muscle bellies were recorded: two sternomastoids, one cleido-occipital and one cleido-mastoid occipital on the right side, and one sternomastoid, one cleido-occipital and two cleido-mastoids on the left side. The variation of bilateral four heads on sternocleidomastoid muscle is important to surgeons and anesthetists for clinical using.

    Diagnosis of ectopic pregnancy continues to be an important challenge. Here a case of incidental diagnosis of bilateral tubal ectopic pregnancy is reported. There was a ruptured tubal ectopic pregnancy on the left side and chronic ruptured tubal ectopic pregnancy on the right side. Leading cause of first trimester maternal deaths is due to complications of ectopic pregnancy. Here an unusual case of ectopic pregnancy is reported in which the patient had spontaneous bilateral tubal ectopic pregnancy which presented with left tubal rupture and subsequently emergency exploratory laparotomy revealed bilateral tubal mass, which on histopathological examination confirmed tubal pregnancy.

    Fibromuscular dysplasia (FMD) describes a group of conditions which cause nonatheromatous arterial stenoses, most commonly of the renal and carotid arteries, typically in young women. We report a rare case of bilateral segmental renal infarction secondary to FMD in a young male patient. His initial presentation with loin pain and pyrexia resulted in a delay in the definitive diagnosis of FMD. He was successfully treated with bilateral balloon angioplasty. The delayed diagnosis in this patient until the condition had progressed to bilateral renal infarcts highlights the need for prompt investigation and diagnosis of suspected cases of FMD.

    Idiopathic scoliosis is a three-dimensional deformity of the growing spine, affecting 2%–3% of adolescents. Although benign in the majority of patients, the natural course of the disease may result in significant disturbance of body morphology, reduced thoracic volume, impaired respiration, increased rates of back pain, and serious esthetic concerns. Risk of deterioration is highest during the pubertal growth spurt and increases the risk of pathologic spinal curvature, increasing angular value, trunk imbalance, and thoracic deformity. Early clinical detection of scoliosis relies on careful examination of trunk shape and is subject to screening programs in some regions. Treatment options are physiotherapy, corrective bracing, or surgery for mild, moderate, or severe scoliosis, respectively, with both the actual degree of deformity and prognosis being taken into account. Physiotherapy used in mild idiopathic scoliosis comprises general training of the trunk musculature and physical capacity, while specific physiotherapeutic techniques aim to address the spinal curvature itself, attempting to achieve self-correction with active trunk movements developed in a three-dimensional space by an instructed adolescent under visual and proprioceptive control. Moderate but progressive idiopathic scoliosis in skeletally immature adolescents can be successfully halted using a corrective brace which has to be worn full time for several months or until skeletal maturity, and is able to prevent more severe deformity and avoid the need for surgical treatment. Surgery is the treatment of choice for severe idiopathic scoliosis which is rapidly progressive, with early onset, late diagnosis, and neglected or failed conservative treatment. The psychologic impact of idiopathic scoliosis, a chronic disease occurring in the psychologically fragile period of adolescence, is important because of its body distorting character and the onerous treatment required, either conservative or surgical

    Diffuse alveolar hemorrhage (DAH) is characterized by the presence of hemoptysis, anemia, and the presence of diffuse parenchymal infiltrates on imaging studies. Idiopathic pulmonary hemosiderosis (IPH) is an uncommon cause of diffuse alveolar hemorrhage (DAH) and is classically known to present in childhood. Adult-onset IPH is extremely rare. We report the case of a 48-year-old female patient who presented with hemoptysis and acute hypoxic respiratory failure, requiring intubation and mechanical ventilation. Imaging studies showed diffuse bilateral patchy infiltrates. Bronchoalveolar lavage (BAL) confirmed the diagnosis of DAH. Extensive workup including video-assisted thoracoscopic surgical lung biopsy (VATS) failed to reveal any vasculitis, infectious, immunological or connective tissue disorder, as the underlying cause for DAH. The patient was successfully treated with high-dose steroid therapy. PMID:26180395

    Central hypersomnias are diseases manifested in excessive daytime sleepiness (EDS) not caused by disturbed nocturnal sleep or misaligned circadian rhythms. Central hypersomnias includes narcolepsy with and without cataplexy, recurrent hypersomnia, idiopathic hypersomnia, with and without long sleep time, behaviorally induced insufficient sleep syndrome, hypersomnia and narcolepsy due to medical conditions, and finally hypersomnia induced by substance intake. The Epworth Sleepiness Scale is a subjective tool mostly used for EDS assessment, while the Multiple Sleep Latency Test serves as an objective diagnostic method for narcolepsy and idiopathic hypersomnias. As for symptomatic therapy of EDS, the central nervous system stimulants modafinil and methylphenidate seem to work well in most cases and in narcolepsy and Parkinson’s disease; sodium oxybate also has notable therapeutic value.

    2016-01-01

    Idiopathic ventricular arrhythmias (VAs) are ventricular tachycardias (VTs) or premature ventricular contractions (PVCs) with a mechanism that is not related to myocardial scar. The sites of successful catheter ablation of idiopathic VA origins have been progressively elucidated and include both the endocardium and, less commonly, the epicardium. Idiopathic VAs usually originate from specific anatomical structures such as the ventricular outflow tracts, aortic root, atrioventricular (AV) annuli, papillary muscles, Purkinje network and so on, and exhibit characteristic electrocardiograms based on their anatomical background. Catheter ablation of idiopathic VAs is usually safe and highly successful, but can sometimes be challenging because of the anatomical obstacles such as the coronary arteries, epicardial fat pads, intramural and epicardial origins, AV conduction system and so on. Therefore, understanding the relevant anatomy is important to achieve a safe and successful catheter ablation of idiopathic VAs. This review describes the anatomical consideration in the catheter ablation of idiopathic VAs.

    Charcot neuroarthropathy in the developed countries is primarily associated with diabetic neuropathy. This study investigated a series of patients with Charcot arthropathy associated with idiopathic peripheral neuropathy to evaluate the natural history in these patients and to evaluate the efficacy of a treatment protocol used for diabetic Charcot joints. The records and radiographs of patients with Charcot arthropathy of the foot and ankle treated between 1986 and 2009 were retrospectively reviewed. Patients with known causes of or risk factors for peripheral neuropathy were excluded, identifying 82 feet in 59 patients with idiopathic neuropathy. Twenty-three (39%) were bilateral. The average age was 76 years and the average follow-up was 60 months. Data were analyzed for medical history and diagnoses, medications, anatomic classification of Charcot arthropathy, history of ulcerations, ambulatory status, shoe wear and bracing, and operative interventions. Patient care was based on previous published treatment algorithms, based on conservative management with operative intervention reserved for nonhealing ulcers, infection, and/or nonplantigrade, unbraceable feet. Therapeutic success was a plantigrade foot with healed soft tissue envelope that allowed weight-bearing. In all, 55% involved the midfoot (type 1), 34% the hindfoot (type 2), and 11% the ankle, (type 3A). Seventy-one of 82 feet were successfully treated at the time of last follow-up. Thirty-six feet (43%) were treated nonoperatively with success in 33 (92%). Forty-six of 82 feet required operative intervention, with success at last follow-up in 38 (83%). There were 8 operative failures resulting in 2 transtibial amputations and 6 feet with persistent ulceration. This series of patients with Charcot arthropathy associated with idiopathic neuropathy demonstrated a wider spectrum of Charcot arthropathy of the foot and ankle than has been previously recognized or documented.

    The purpose of this study was to determine the effects of botulinum toxin type A treatment on ankle muscle activity during gait of children who are idiopathic toe-walkers. Five children who were idiopathic toe-walkers with a mean age was 4.34 years participated. Gait of the subjects was evaluated prior to, 20 days following, and 12 months following bilateral botulinum toxin type A injection of the gastrocnemius and soleus muscles. Subjects received physical therapy following the 20-day evaluation. Dependent variables were type of foot contact pattern and duration of swing-phase tibialis anterior activity and onset of stance-phase gastrocnemius relative to ground contact. Prior to treatment 51% of foot contacts were with the toe (heel just off the ground) or were digitigrade, while the remaining contacts were flat foot or heel strike. At approximately 20 days following treatment, only 8% of foot contacts were toe contact or digitigrade. Prior to treatment, mean gastrocnemius onset was 30 ms prior to foot contact and the duration of swing-phase tibialis anterior was only 345 ms. Following treatment (and a more normal foot contact pattern), mean gastrocnemius onset followed ground contact by 36 ms and tibialis anterior duration increased through terminal swing and into the loading response. The posttreatment improvement was maintained at 12-month follow-up. It appears that botulinum toxin type A treatment normalizes the ankle EMG pattern during gait and a more normal foot-strike pattern is obtained. These data are discussed in terms of a neuromotor rationale for the rehabilitation of children who are idiopathic toe-walkers to maintain posttreatment improvements.

    In this study, the authors investigated the superficial multifidus muscle in patients with idiopathic scoliosis. During spinal fusion, biopsies were taken bilaterally at the apex of the curve, and at the upper and lower end vertebrae. To analyze the muscular reactions in response to bracing in patients with idiopathic scoliosis. The extent to which intervertebral mobility is restricted by an orthosis is still controversial. In addition, the effect of bracing on the erector spinae has not been investigated. Of a total 30 patients, 11 had been treated with a corset for a year or more before surgery. Biopsies were investigated histochemically and the muscle fibers classified as Type I, IIA, IIB, or IIC (transitional fibers). The relative distribution of the fibers was calculated and their diameter was measured. In unbraced patients, a shift in the fiber distribution (from "slow" to "fast") was observed exclusively at the concave side of the apex. This shift was paralleled by an increased percentage of the intermediate Type IIC fiber (indicative of fiber transformation). In patients who always wore a corset, the relative amount of Type IIC fibers was increased, without preference for a specific location. Corset treatment elicits muscle fiber transformation processes at different levels along the scoliosis. This general reaction of the paraspinal muscles provides strong evidence against the existence of muscular disorders that are restricted to the area of the apex and are thus causing the scoliosis. As such, it must be assumed that the muscular changes in the apical region are secondary.

    Objective Since the term "combined pulmonary fibrosis and emphysema" (CPFE) was first proposed, the co-existence of pulmonary fibrosis and pulmonary emphysema (PE) has drawn considerable attention. However, conflicting results on the clinical characteristics of patients with both pulmonary fibrosis and PE have been published because of the lack of an exact definition of CPFE. The goal of this study was thus to clarify the clinical characteristics and phenotypes of idiopathic interstitial pneumonia (IIP) with PE. Methods We retrospectively analyzed IIP patients who had been admitted to our hospital. Their chest high-resolution computed tomography images were classified into two groups according to the presence of PE. We then performed a cluster analysis to identify the phenotypes of IIP patients with PE. Results Forty-four (53.7%) out of 82 patients had at least mild emphysema in their bilateral lungs. The cluster analysis separated the IIP patients with PE into three clusters. The overall survival rate of one cluster that consisted of mainly idiopathic pulmonary fibrosis (IPF) patients was significantly worse than those of the other clusters. Conclusion Three different phenotypes can be identified in IIP patients with PE, and IPF with PE is a distinct clinical phenotype with a poor prognosis.

    Individuals with Parkinson’s disease (PD) often exhibit deficits in visuospatial functioning throughout the course of their disease. These deficits should be carefully assessed as they may have implications for patient safety and disease severity. One of the most commonly administered tests of visuospatial ability, the Benton Judgment of Line Orientation (JLO), consists of 30 pairs of lines requiring the patient to match the orientation of two lines to an array of 11 lines on a separate page. Reliable short forms have been constructed out of the full JLO form, but the reliability of these forms in PD has yet to be examined. Recent functional MRI studies examining the JLO demonstrate right parietal and occipital activation, as well as bilateral frontal activation and PD is known to adversely affect these pathways. We compared the reliability of the original full form to three unique short forms in a sample of 141 non-demented, idiopathic PD patients and 56 age and education matched controls. Results indicated that a two-thirds length short form can be used with high reliability and classification accuracy in patients with idiopathic PD. The other short forms performed in a similar, though slightly less reliable manner. PMID:23957375

    : Osteochondroses are a group of idiopathic self-limited conditions seen in skeletally immature individuals. The term describes disturbances in endochondral ossification affecting either the primary or secondary ossification centers. Osteochondrosis of the tarsal navicular was first described by Köhler in 1908; the eponym "Köhler's disease" is commonly used to refer to this condition. In his original paper, Köhler also described one instance of an osteochondrosis of the primary patellar ossification center, a clinical entity that has since rarely been reported. We present a case of isolated bilateral "Köhler's disease of the patellae" in an approximately 7-year-old male athlete demonstrated clinically and radiographically by both plain radiographs and magnetic resonance imaging.

    The purpose of this study was to evaluate the bilateral coordination in children and adolescents with visual impairments aged 7 to 18 years in comparison to their sighted peers. An additional objective was to identify the influence of sex and age on bilateral coordination. Seventy-five individuals with congenital severe visual impairment (40 girls and 35 boys) comprised the visually impaired group. The Sighted group comprised 139 youth without visual impairment. Subtest 4 of the Bruininks-Oseretsky Test of Motor Proficiency was administered to test bilateral coordination. To analyze the effect of the independent variables in the results obtained in the Subtest 4, four linear regression models were applied according to group and sex. The results indicated that severe visual impairment and lack of visual sensation had a negative effect on the development of participants' bilateral coordination, which however did not depend on sex or age. © The Author(s) 2016.

  15. Mitochondrial dysfunction in idiopathic Parkinson disease.

    1998-04-01

    Disordered mitochondrial metabolism may play an important role in a number of idiopathic neurodegenerative disorders. The question of mitochondrial dysfunction is particularly attractive in the case of idiopathic Parkinson disease (PD), since Vyas et al. recognized in the 1980s that the parkinsonism-inducing compound N-methyl-4-phenyl-1,2,3,6-tetrahydropyridine is a mitochondrial toxin. The unique genetic properties of mitochondria also make them worthy of consideration for a pathogenic role in PD, as well as in other late-onset, sporadic neurodegenerative disorders. Although affected persons occasionally do provide family histories that suggest Mendelian inheritance, the vast majority of the time these diseases appear sporadically. Because of unique features such as heteroplasmy, replicative segregation, and threshold effects, mitochondrial inheritance can allow for the apparent sporadic nature of these diseases.

    The term idiopathic noncirrhotic portal hypertension (INCPH) has been recently proposed to replace terms, such as hepatoportal sclerosis, idiopathic portal hypertension, incomplete septal cirrhosis, and nodular regenerative hyperplasia, used to describe patients with a hepatic presinusoidal cause of portal hypertension of unknown etiology, characterized by features of portal hypertension (esophageal varices, nonmalignant ascites, porto-venous collaterals), splenomegaly, patent portal, and hepatic veins and no clinical and histological signs of cirrhosis. Physicians should learn to look for this condition in a number of clinical settings, including cryptogenic cirrhosis, a disease known to be associated with INCPH, drug administration, and even chronic alterations in liver function tests. Once INCPH is clinically suspected, liver histology becomes mandatory for the correct diagnosis. However, pathologists should be familiar with the histological features of INCPH, especially in cases in which histology is not only requested to exclude liver cirrhosis. PMID:27555800

    The aim of this article is to study the evidence-based knowledge related to the use of biological therapies in patients diagnosed with idiopathic inflammatory myopathy (dermatomyositis, polymyositis and inclusion body myositis). In this review the leading published studies related to the use of biological therapy in patients with myositis are analysed; mainly those with high methodological standards, that means randomized and controlled studies. Methodological drawbacks due to the rarity and heterogeneity of these complex diseases are also addressed. Up to now is not possible to ascertain the biologics as a recommended therapy in patients with myositis, at least based in the current evidence-based knowledge, although it can not be neglected as a therapeutic option in some clinical situations, taking into account the scarce of effective treatments in those patients, especially in refractory myositis. Future studies probably will help to better define the role of biological therapies in patients with idiopathic inflammatory myopathy.

    Mental retardation is a heterogeneous condition, affecting 1-3% of general population. In the last few years, several emerging clinical entities have been described, due to the advent of newest genetic techniques, such as array Comparative Genomic Hybridization. The detection of cryptic microdeletion/microduplication abnormalities has allowed genotype-phenotype correlations, delineating recognizable syndromic conditions that are herein reviewed. With the aim to provide to Paediatricians a combined clinical and genetic approach to the child with cognitive impairment, a practical diagnostic algorithm is also illustrated. The use of microarray platforms has further reduced the percentage of "idiopathic" forms of mental retardation, previously accounted for about half of total cases. We discussed the putative pathways at the basis of remaining "pure idiopathic" forms of mental retardation, highlighting possible environmental and epigenetic mechanisms as causes of altered cognition.

    Scrotal elephantiasis is very rare disease in industrialized countries, where it is mainly due to surgery, irradiation or malignancies. It can be defined as idiopathic only when the possible congenital, infectious and compressive causes are excluded. We report a case of massive scrotal lymphoedema in an adult Caucasian patient, in Italy. He presented an extremely voluminous scrotal mass measuring 50 x 47 x 13 cm (weight 18 kg), which extended below his knees, invalidating all his daily activities. The patient was hospitalized in order to undergo to surgical treatment. Although genetic causes were searched and the possible role of infectious agents and compressive factors was evaluated, no etiology was ascertained. Histopathologic examination showed non-specific chronic inflammation, confirming the diagnosis of idiopathic elephantiasis. One year after surgical treatment, the patient is healthy without recurrence signs.

    2015-01-01

    Idiopathic (viral) pericarditis is the most common form of pericardial disease in the Western world. Despite the combination of colchicine and nonsteroidal antiinflammatory drugs (NSAIDs) plus aspirin (ASA), considered first-line therapy, the incidence of recurrent pericarditis is ~20-30%. In addition, secondary recurrence without optimal first-line therapy is ~50%. This is due to the many clinical challenges, such as inappropriate NSAID/ASA duration of therapy, the use of corticosteroid therapy, contraindications or intolerances to therapy, adverse effects, and issues related to adherence. This review describes contemporary pharmacotherapeutic management of idiopathic (viral) pericarditis, with a particular emphasis on the role of colchicine. Emerging therapies and management strategies, such as high-sensitivity C-reactive protein-guided therapy and novel immunotherapies, are also reviewed. Ultimately, understanding appropriate treatment will assist the clinician in helping decrease the risk of recurrent, incessant, and refractory pericarditis.

    2016-01-01

    Summary Idiopathic pulmonary fibrosis (IPF), a devastating progressive interstitial lung disease (ILD) with no known cause or cure, is the most common and deadly of the idiopathic interstitial pneumonias. With a median survival of 3–5 years following diagnosis, IPF is characterized by a progressive decline in lung function and quality of life in most patients. Vigilance among clinicians in recognizing IPF early in the disease course remains critical to properly caring for these patients, as this provides the widest range of management options. When IPF is suspected, a multidisciplinary evaluation (MDE) by a clinician, radiologist and pathologist with ILD expertise should occur, as this improves diagnostic agreement in both community and academic settings. When community MDE is not possible, or diagnostic doubt exists, referral to an ILD center should be considered. ILD center referral may also provide access specialized care, including clinical trials and lung transplantation, and should be considered for any patient with an established diagnosis of IPF.

    Skeletally immature patients with adolescent idiopathic scoliosis are at risk for curve progression. Although numerous nonoperative methods have been attempted, including physical therapy, exercise, massage, manipulation, and electrical stimulation, only bracing is effective in preventing curve progression and the subsequent need for surgery. Brace treatment is initiated as either full-time (TLSO, Boston) or nighttime (Charleston, Providence) wear, although patient compliance with either mode of bracing has been a documented problem. We review the natural history of adolescent idiopathic scoliosis, identify the risks for curve progression, describe the types of braces available for treatment, and review the indications for and efficacy of brace treatment. Level of Evidence: Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence. PMID:19484317

    Idiopathic scoliosis is a three-dimensional deformity of the spine. The most common form is diagnosed in adolescence. While adolescent idiopathic scoliosis (AIS) can progress during growth and cause a surface deformity, it is usually not symptomatic. However, in adulthood, if the final spinal curvature surpasses a certain critical threshold, the risk of health problems and curve progression is increased. To evaluate the efficacy of bracing for adolescents with AIS versus no treatment or other treatments, on quality of life, disability, pulmonary disorders, progression of the curve, and psychological and cosmetic issues. We searched CENTRAL, MEDLINE, EMBASE, five other databases, and two trials registers up to February 2015 for relevant clinical trials. We also checked the reference lists of relevant articles and conducted an extensive handsearch of grey literature. Randomized controlled trials (RCTs) and prospective controlled cohort studies comparing braces with no treatment, other treatment, surgery, and different types of braces for adolescent with AIS. We used standard methodological procedures expected by The Cochrane Collaboration. We included seven studies (662 participants). Five were planned as RCTs and two as prospective controlled trials. One RCT failed completely, another was continued as an observational study, reporting also the results of the participants that had been randomized.There was very low quality evidence from one small RCT (111 participants) that quality of life (QoL) during treatment did not differ significantly between rigid bracing and observation (mean difference (MD) -2.10, 95% confidence interval (CI) -7.69 to 3.49). There was very low quality evidence from a subgroup of 77 adolescents from one prospective cohort study showing that QoL, back pain, psychological, and cosmetic issues did not differ significantly between rigid bracing and observation in the long term (16 years).Results of the secondary outcomes showed that there was low

    Fahr's disease is rare a neurodegenerative idiopathic condition characterized by symmetric and bilateral calcifications of basal ganglia, usually associated with progressive neuropsychiatric dysfunctions and movement disorders. The term "Fahr's syndrome" is used in presence of calcifications secondary to a specific cause, but the variability of etiology, pathogenesis, and clinical picture underlying this condition have raised the question of the real existence of a syndrome. Several classifications based on the etiology, the location of brain calcifications and the clinical presentation have been proposed. Here we describe seven clinical cases of basal ganglia calcifications, in order to search for pathognomonic features and correlations between clinical picture and imaging findings. The patients came to our attention for different reasons (most of them for memory/behavior disturbances); all underwent neuro-psychologic evaluation and neuro-imaging. All patients showed variable degrees of deterioration in cognitive function; anxiety and depression were frequent too, and resistant to treatment in all cases. Less frequent, but severe if present, were psychotic symptoms, with different grade of structure and emotional involvement, and always resistant to treatment. We observed only few cases of extrapyramidal disorders related to the disease itself; anyway, mild extrapyramidal syndrome occurred quite frequently after treatment with antipsychotics. Based on these findings we discourage the use of the term "Fahr's syndrome", and suggest to refer to Idiopathic or Secondary basal ganglia calcification. Unlike early onset forms (idiopathic or inherited), the clinical presentation of late onset form and Secondary basal ganglia calcification seems to be really heterogeneous. Case-control studies are necessary to determine the actual significance of basal ganglia calcification in the adult population and in the elderly, in cognitive, physical and emotional terms.

    We report a case of bilateral pneumolabyrinth presenting as sudden, bilateral deafness, without temporal bone fracture, after a fall. A 49-year-old man presented with sudden, bilateral deafness and whirling vertigo, without any other neurological manifestations. Temporal bone computed tomography clearly demonstrated the presence of air in the vestibule and cochlea on both sides. However, there was no definite fracture line, ossicular chain anomaly or soft tissue density in the temporal bone or middle-ear cavity. The patient was treated conservatively. Unfortunately, there was no improvement in his hearing. Pneumolabyrinth is an uncommon condition in which air is present in the vestibule or cochlea. It is rarely found, even with fractures violating the otic capsule or with transverse fractures of the temporal bone. In addition, its bilateral occurrence is extremely rare. In this article, we describe a case of bilateral pneumolabyrinth presenting as sudden, bilateral deafness, without temporal bone fracture, an occurrence which has not previously been reported.

  8. The etiology and pathogenesis of idiopathic scoliosis.

    PubMed

    Dickson, R A

    1992-01-01

    Idiopathic scoliosis is a complex three-dimensional deformity and in the thoracic region the essential lesion lies in the sagittal plane in the form of an area of inappropriate lordosis. The thoracic kyphosis is normally protected from buckling by being behind the axis of spinal column rotation but when the thoracic lordosis develops it brings the apical region anterior to this axis and thus under compression with resultant buckling failure of the spinal column. The condition of idiopathic thoracic scoliosis is the opposite to idiopathic hyperkyphosis (Scheuermann's disease), the latter being rotationally stable and not moving out of the sagittal plane. The two frequently co-exist in the same spine with thoracic hyperkyphosis above an area of lumbar lordo-scoliosis. There is a spectrum of normal lateral profile and flat backs at the one end are in danger of buckling (lordo-scoliosis) while round backs at the other end of the spectrum are in danger of being defined as Scheuermann's disease. There is no requirement for a specific pathological process. Engineers describe only two ways in which a flexible column can fall into mechanically-angular collapse (kyphosis) and column buckling (lordo-scoliosis). A number of factors favour column buckling (Euler's law) and thus the bigger a deformity the more likely it will be to continue progressing and the taller and more slender the column the more likely it will be to fail and this we see in our patients with idiopathic scoliosis. Not only is lordosis the essential lesion but it is also the primary abnormality which can be demonstrated in children before lateral curvature and rotation develop.

    Background Cellular changes associated with diabetic and idiopathic gastroparesis are not well described. Aim Describe histologic abnormalities in gastroparesis and compare findings in idiopathic versus diabetic gastroparesis. Methods Full thickness gastric body biopsies were obtained from 40 gastroparetics (20 diabetic) and matched controls. Sections were stained for H&E and trichrome, and immunolabeled with antibodies against PGP 9.5, nNOS, VIP, substance P and tyrosine hydroxylase to quantify nerves, S100β for glia, Kit for interstitial cells of Cajal (ICC), CD45 and CD68, for immune cells and smoothelin for smooth muscle cells. Tissue was also examined by transmission electron microscopy (TEM). Results Histological abnormalities were found in 83% of patients. Most common defects were loss of ICC with remaining ICC showing injury, an abnormal immune infiltrate containing macrophages, and decreased nerve fibers. On light microscopy, no significant differences were found between diabetic and idiopathic gastroparesis with the exception of nNOS expression which was decreased in more idiopathic gastroparetics (40%) compared to diabetic (20%) patients by visual grading. On electron microscopy, a markedly increased connective tissue stroma was present in both disorders. Conclusion This study suggests that on full thickness biopsies, cellular abnormalities are found in the majority of patients with gastroparesis. Most common findings were loss of Kit expression suggesting loss of ICC and an increase in CD45 and CD68 immunoreactivity. These findings suggest that examination of tissue can lead to valuable insights into the pathophysiology of these disorders and offers hope that new therapeutic targets can be found. PMID:21300066

    Idiopathic spinal cord herniation is a rare cause of thoracic myelopathy and its recurrence is even more infrequent. Cord herniation is through an anterior dural defect in thoracic spine with unknown causes. Symptomatic cases must be surgically treated to reduce the hernia and seal the defect to prevent recurrences. We report a patient presenting a Brown-Séquard syndrome secondary to a D5 spinal cord herniation treated successfully and its posterior traumatic recurrence.

    We report the histopathologic findings in two cases of idiopathic calcifying tenosynovitis, one involving the insertion of the right pectoralis minor tendon, and the other the left ring finger proximal interphalangeal joint of a 54-year-old male and a 28-year-old female, respectively. At operation, cream cheese-like material was identified in each case. Sections of tendon in the first case showed numerous circumscribed lesions in various stages of evolution. Early lesions consisted of central granular or globular proteinaceous material surrounded by histiocytes, lymphocytes, and foreign-body giant cells, with a peripheral network of small blood vessels. Larger, more mature lesions contained similar proteinaceous material, but had central cavitation, a thinner reactive inflammatory zone, and a fibrous capsule. The largest lesions were cystic, had no proteinaceous material or significant inflammatory zone, and had a thick fibrous capsule. No calcification was identified in the intratendinous lesions. In contrast, the hyperplastic synovium and other peritendinous tissues contained numerous round psammoma-like calcifications. It is concluded that the synovial and peritendinous psammoma-like calcifications in our cases represent a reaction to a primary tendinous lesion, which may be a consequence of ischemia or persistent mild trauma.

    Idiopathic toe walking, a differential diagnosis for neurological and orthopaedic disorders, has been associated with neurodevelopmental alterations. Neurodevelopmental assessment at early ages using specific tests may improve management and follow-up of these patients. The aim of our study is to analyse the neurodevelopmental characteristics of preschool idiopathic toe-walkers (ITW) by comparing them to a control group. Our descriptive cross-sectional study compared possible risk factors, neurodevelopmental characteristics, and scores on the Child Neuropsychological Maturity Questionnaire (CUMANIN) between a group of 56 ITWs aged 3 to 6 and a control group including 40 children. The proportion of males was significantly higher in the ITW group (P=.008). The percentage of patients with a family history (P=.000) and biological risk factors during the perinatal period (P=.032) was also higher in this group. According to the parents' reports, motor coordination in ITWs was significantly poorer (59%; P=.009). ITWs scored significantly lower on CUMANIN subscales of psychomotricity (=0,001) and memory (P=.001), as well as in verbal development (P=.000), non-verbal development (P=.026), and overall development (P=.004). Foot preference was less marked in the ITW group (P=.047). The neurodevelopmental characteristics of our sample suggest that idiopathic toe walking is a marker of neurodevelopmental impairment. However, further studies are necessary to confirm these findings. Copyright © 2016 Sociedad Española de Neurología. Publicado por Elsevier España, S.L.U. All rights reserved.

    Purpose: To evaluate the usefulness of interventional radiological treatment for idiopathic portal hypertension. Methods: Between 1995 and 1998, we performed an interventional radiological treatment in five patients with idiopathic portal hypertension, four of whom had refused surgery and one of whom had undergone surgery. Three patients with gastroesophageal varices (GEV) were treated by partial splenic embolization (PSE), one patient with esophageal varices (EV) and massive ascites by transjugular intrahepatic portosytemic shunt (TIPS) and PSE, and one patient with GEV by percutaneous transhepatic obliteration (PTO). Midterm results were analyzed in terms of the effect on esophageal and/or gastric varices. Results: In one woman with severe GEV who underwent three sessions of PSE, there was endoscopic confirmation that the GEV had disappeared. In one man his EV shrunk markedly after two sessions of PSE. In two patients slight reduction of the EV was obtained with one application of PSE combined with endoscopic variceal ligation therapy. PTO for GV in one patient resulted in good control of the varices. All patients have survived for 16-42 months since the first interventional treatment, and varices are well controlled. Conclusion: Interventional radiological treatment is effective for patients with idiopathic portal hypertension, whether or not they have undergone surgery.

    Although external root resorption (ERR) is a physiological process in deciduous dentition, it is very infrequent in permanent dentition - where the phenomenon is related to the existence of inadequate occlusal forces, periodontal pathology and microtraumatisms, etc. However, in many cases root resorption cannot be attributed to any concrete cause; such cases are defined as idiopathic external root resorption (IERR). Epidemiological studies have found that the underlying cause can only be established in 5% of all ERR. The present study describes three cases of IERR with different degrees of involvement and associated to mild calciuria and a history of nephrolithiasis. Hypercalciuria with normal blood calcium levels is usually idiopathic and exhibits a familial trait, with a prevalence of 20-40 cases per 1,000 individuals in adults. A form of hypercalciuria associated to nephrolithiasis with a mutation of the CLCN5 gene has been identified, involving low molecular weight proteinuria - though this mutation has not been uniformly demonstrated in most cases of idiopathic hypercalciuria. The peculiarity of the cases described in the present study is attributable to the coexistence of IERR with normocalcemic hypercalciuria and nephrolithiasis - thus pointing to the need for in-depth evaluation of the possible association of these three clinical situations.

    Fibrosing interstitial lung diseases (f-ILDs) represent a heterogeneous group of disorders in which the aetiology may be identified or, not infrequently, remain unknown. Establishing a correct diagnosis of a distinct f-ILD requires a multidisciplinary approach, integrating clinical profile, physiological and laboratory data, radiological appearance and, when appropriate, histological findings. Surgical lung biopsy is still considered the most important diagnostic tool as it is able to provide lung samples large enough for identification of complex patterns such as usual interstitial pneumonitis (UIP) and nonspecific interstitial pneumonitis. However, this procedure is accompanied by significant morbidity and mortality. Bronchoalveolar lavage is still a popular diagnostic tool allowing identification of alternative diagnoses in patients with suspected idiopathic pulmonary fibrosis (IPF) when an increase in lymphocytes is detected. Conventional transbronchial lung biopsy has a very low sensitivity in detecting the UIP pattern and its role in this clinical-radiological context is marginal. The introduction of less invasive methods such as transbronchial cryobiopsy show great promise to clinical practice as they can be used to obtain samples large enough to morphologically support a diagnosis of IPF or other idiopathic interstitial pneumonias, along with fewer complications. Recent advances in the field suggest that less invasive methods of lung sampling, without significant side effects, in combination with other diagnostic methods could replace the need for surgical lung biopsy in the future. Indeed, these new multidisciplinary procedures may become the main diagnostic work-up method for patients with suspected idiopathic interstitial pneumonia.

    Idiopathic hypothalamic dysfunction is a rare disorder presenting at age 3-7 years. Severe hypothalamic and brainstem dysfunction leads to death in 25% of patients. The disease is presumed to be autoimmune, or in some cases paraneoplastic. No successful treatment has been reported. Patient V. developed hyperphagia, hypersomnia, and extreme aggression at age 7 years, accompanied by episodes of hyperthermia, hypothermia, sinus bradycardia, hypernatremia, hyponatremia, persistent hyperprolactinemia, hypothyroidism, and growth-hormone deficiency. At age 9 years, a diagnosis of idiopathic hypothalamic dysfunction was rendered, and immunoglobulin therapy was commenced. Nine courses of immunoglobulins, at a dose of 2 g/kg every 4 weeks, were administered. Reproducible improvements in behavior and no further episodes of hyponatremia or hypernatremia and sinus bradycardia were evident. The endocrinologic abnormalities and poor thermoregulation remained. Administration of immunoglobulins during late stages of idiopathic hypothalamic dysfunction led to improvement in some but not all signs. Assuming an autoimmune basis for this disorder, treatment during early stages of disease should be more effective. To facilitate such early treatment, increased awareness of this disorder is necessary, to allow for early diagnosis.

    Idiopathic fascicular ventricular tachycardia is an important and not very rare cardiac arrhythmia with specific electrocardiographic features and therapeutic options. Ventricular tachycardia is characterized by relatively narrow QRS complex and right bundle branch block pattern. The QRS axis depends on which fascicle is involved in the re-entry. Left axis deviation is noted with left posterior fascicular tachycardia and right axis deviation with left anterior fascicular tachycardia. A left septal fascicular tachycardia with normal QRS axis is also possible. Idiopathic fascicular tachycardia is usually seen in individuals without structural heart disease. Response to verapamil is an important feature of fascicular tachycardia. In some cases intravenous adenosine may also terminate the arrhythmia. During electrophysiology study, presystolic or diastolic potentials precede the QRS, presumed to originate from the Purkinje fibers. The potentials can be recorded during sinus rhythm and ventricular tachycardia in many patients with fascicular tachycardia. This potential (so-called Purkinje potential) has been used as a guide to catheter ablation. Correct diagnosis of fascicular tachycardia is very important because catheter ablation is very effective in the treatment of this type of ventricular tachycardia. In this review, we describe three patients with idiopathic ventricular tachycardia and their successful catheter ablation, and summarize the actual knowledge of the diagnosis and management of this special ventricular tachycardia.
