Effectiveness of novel facial stretching with structured exercise versus conventional exercise for Bell's palsy: a single-blinded randomized clinical trial.

The purpose of the study was to assess the effects of a novel technique involving facial stretching of the unaffected side along with a structured exercise for the affected side on facial symmetry and facial functions as compared to conventional exercise. A hospital-based parallel-group randomized trial was completed among patients with acute Bell's palsy in Mangalore, India. Participants were randomized to receive facial stretching and a structured exercise program (experimental group) or the conventional exercise regimen (conventional group). Primary outcomes were facial symmetry and voluntary movement; assessed by the Sunnybrook Facial Grading System (SFGS). Both regimens were given for 3 weeks, with baseline, 10th day, and 20th day assessments. Out of 31 participants screened, 24 were eligible and 12 participants each were assigned to experimental and conventional groups. Change scores revealed greater improvement in the SFGS score (p = 0.002) for the experimental group participants. Facial stretching and structured exercise program exhibited promising results in enhancing facial symmetry and function in acute Bell's palsy when compared to conventional exercise regimen.

Can Serum Magnesium Level and Visual Evoked Potentials (P100) be a Predictive in Migraineurs?: Evidence Based Study.

Background and Objective: Few dating back, the role of visual evoked potentials changes and reduced level of intracellular magnesium have appeared in migraine patients both throughout the attacks and in the interictal periods. Moreover, there is a lack of evidence regarding the correlation between magnesium levels and visual evoked potentials. To assess the changes in the levels of magnesium in migraineurs compared to a healthy control group is our prime intention. Also, to correlate serum magnesium levels with visual evoked potentials changes within the migraineurs is a secondary part of the study. Materials and Methods: After applying inclusion and exclusion criteria as per the study protocol, in total, 80 subjects were enrolled in the study. Of which 40 were migraineurs diagnosed as per the International Headache Society criteria for severe migraine headache. Rest of 40 was nonmigraineurs served as a control group of the study. All included patient was submitted to demographic profile, previous history of the disease and drug intake, thorough clinical investigation and baseline laboratory parameters. Apart from this, the measurement of visual evoked potentials changes (4th block) and magnesium levels were done as per our standard operating procedures. Results: In migraineurs, serum total Mg level was considerably lower compared to the control group (1.79 ± 0.14 mg/dl versus 2.10 ± 0.17 mg/dl, P < 0.0001) and amplitude of P100 (P < 0.0001) was negatively correlated to reduced serum Mg level (P < 0.0001). Conclusions: As expected, both elevated visual evoked potential amplitude and reduced level of brain magnesium can be a demonstration of neuronal hyperexcitability of the optic pathways associated with a dropped threshold for migraine attacks.

Combination antiretroviral therapy improves recurrent primary biliary cholangitis following liver transplantation.

Recurrent primary biliary cholangitis (rPBC) is frequent following liver transplantation and associated with increased morbidity and mortality. It has been argued that rPBC behaves like an infectious disease because more potent immunosuppression with tacrolimus is associated with earlier and more severe recurrence. Prophylactic ursodeoxycholic acid is an established therapeutic option to prevent rPBC, whereas the role of second line therapies, such as obeticholic acid and bezafibrate in rPBC, remains largely unexplored. To address the hypothesis that a human betaretrovirus plays a role in the development of PBC, we have tested antiretroviral therapy in vitro and conducted randomised controlled trials showing improvements in hepatic biochemistry. Herein, we describe the utility of combination antiretroviral therapy to manage rPBC in two patients treated with open label tenofovir/emtricitabine-based regimens in combination with either lopinavir or raltegravir. Both patients experienced sustained biochemical and histological improvement with treatment, but the antiretroviral therapy was associated with side effects.

Sudden Hearing Loss and Multiple Cranial Nerve Palsies in Autoimmune disease: A Case Report.

INTRODUCTION: The relationship between autoimmune disease and sensorineural loss is well documented in literature. Immune mediated sudden hearing loss is asymmetric, bilateral and rapidly progressive but responds well to steroid therapy. However association of cranial nerve neuropathies with sudden hearing loss is rare. CASE REPORT: A 41 year old female presented with sudden mixed hearing loss and developed multiple cranial nerve palsies within a month. Blood and Cerebrospinal fluid analysis revealed an undiagnosed rheumatoid arthritis. She responded well to definitive therapy with cyclophosphamide and azathioprine. CONCLUSION: If sudden hearing loss is associated with cranial neuropathy, an autoimmune work-up is highly recommended.

Autologous stem cell transplantation for multiple myeloma: Long-term results.

BACKGROUND: Survival of myeloma patients has improved considerably in the past decade. However, limited data are available on their long-term outcome. We analysed the data of 225 consecutive patients who underwent autologous stem cell transplantation (ASCT) at our centre. METHODS: Between April 1990 and December 2013, a total of 225 patients with multiple myeloma (median age 53 years, range 27-67 years, 69.3% men) underwent ASCT. High-dose melphalan 200 mg/m2 was used for conditioning. Before transplant, the patients received induction therapy with novel agents (thalidomide and dexamethasone, or lenalidomide and dexamethasone, or bortezomib and dexamethasone); or vincristine, doxorubicin, dexamethasone; or alkylating agents (vincristine, melphalan, cyclophosphamide and prednisolone; or melphalan and prednisolone). The response to transplant was evaluated using the European Bone Marrow Transplant criteria, and an intention-to-treat analysis was done. RESULTS: Four-fifths (79.6%) of our patients had Durie Salmon Stage (DSS) IIIA and nearly a quarter (24%) of them had International Stage III disease. Before the transplant, 80.4% of patients had chemosensitive disease. The median interval from diagnosis to transplant was 10 months (range 2-128 months). Following ASCT, 197 (87.5%) patients responded. Complete response was obtained in 54.7%, very good partial response in 19% and partial response in 13.8%. At a median follow-up of 90 months (range 18-266 months), the median progression-free survival (PFS) and overall survival (OS) were 32 and 85.5 months, respectively. The estimated PFS and OS at 10 years were 29.7% and 43.6%, respectively. On multivariate analysis, the presence of extramedullary disease (HR 3.05, p < 0.001), and ISS III (HR 0.50, p < 0.02) predicted inferior OS. Extramedullary disease at diagnosis (HR 1.585, p < 0.03), and more than one regimen pre- transplant (HR 0.53, p < 0.02) predicted an inferior PFS. Complete response was a predictor of superior OS and PFS (p < 0.001). CONCLUSION: Complete response following ASCT is associated with good long-term outcome. Alternative treatment strategies are needed to improve results in patients who fail to achieve CR post-transplant and in those with high-risk disease.

Neurologic melioidosis presented as encephalomyelitis and subdural collection in two male labourers in India.

UNLABELLED: Two distinct and potentially deceitful cases of neurologic melioidosis are reported. Case 1: A 39-year-old alcoholic and uncontrolled diabetic male presented with cough, fever, and left focal seizures with secondary generalization. An magnetic resonance imaging (MRI) brain scan revealed a small peripherally enhancing subdural collection along the interhemispheric fissure suggestive of minimal subdural empyema. Blood culture grew Burkholderia pseudomallei. Patient was diagnosed with disseminated bacteraemic melioidosis with subdural empyema. He was successfully treated with ceftazidime-cotrimoxazole-doxycycline. Case 2: A 45-year-old male presented with left lower limb weakness, difficulty in passing urine and stool, and back pain radiating to lower limbs. Neurological examination revealed flaccid left lower limb with absent deep tendon reflexes and plantar reflex. Spinal MRI showed T2 hyperintensity from D9 to L1 suggestive of demyelination. Patient was treated with high dose methylprednisolone. By day 3 of steroid treatment, lower limb weakness progressed. Subsequent MRI showed extensive cord hyperintensity on T2 weighted sequence extending from C5 to conus medullaris consistent with demyelination. Cerebrospinal fluid (CSF) culture grew B. pseudomallei, and the patient was given meropenem-cotrimoxazole. After three weeks of parenteral treatment, the lower limbs remained paralyzed. Patient was discharged on oral cotrimoxazole-doxycycline. CONCLUSIONS: Melioidosis should be considered as a differential in focal suppurative central nervous system (CNS) lesions, meningoencephalitis, or encephalomyelitis in endemic areas. CNS infections must be ruled out prior to steroid administration. The role of corticosteroids in demyelinating CNS melioidosis has been refuted. This is a rare documentation of effect of unintentional corticosteroid treatment in melioidosis.

Hepatitis B in pregnancy: a concise review of neonatal vertical transmission and antiviral prophylaxis.

Hepatitis B is a chronic viral infection of the liver leading to complications including cirrhosis and hepatocellular carcinoma. The leading cause of acquisition is vertical transmission from an infected mother to the newborn. Despite newborn immunoprophylaxis, vertical transmission may still occur in 1-14%. The aim of this article is to provide a concise review of the mechanisms and risk factors involved in vertical transmission, as well as prophylactic strategies using immunoprophylaxis and antiviral medications. Mechanisms of vertical transmission include intrauterine and perinatal transfer of virus. High HBV viral load and presence of HBeAg increases risk of transmission. Combination vaccine and hepatitis B immunoglobulin given at birth reduces risk of transmission, as does HBIG given to mothers in the third trimester. Three antivirals have been studied in pregnancy: lamivudine, telbivudine, and tenovofir. All have shown significant reduction in viral loads and vertical transmission and have favorable safety profiles. In conclusion, HBV vertical transmission is preventable through use of immunoprophylaxis and antiviral medications. Recommendation for antiviral use in third trimester in mothers whose HBV VL is greater than 1 x 106 copies/mL.

Chronic hepatitis C in Western Canada: a survey of practice patterns among gastroenterologists in Alberta and British Columbia.

OBJECTIVE: To survey gastroenterologists in British Columbia and Alberta with regard to awareness of chronic hepatitis C virus (HCV) management and practice patterns among physicians who treat and do not treat HCV-infected patients. METHODS: An anonymous two-page mail survey was distributed to actively practicing adult gastroenterologists in British Columbia and Alberta. Among physicians who treated HCV patients, respondents answered assessment of fibrosis pretreatment, measurement of rapid virological response, prescription of protease inhibitors (PIs), barriers to using these agents and referral patterns. For those who did not treat HCV, referral of patients for treatment and to whom was assessed. RESULTS: Seventy-seven of 166 individuals completed the survey (46% response rate). Most (49%) practiced in academic or large community (42%) settings. Chronic liver disease comprised <25% of individual practice in 71%. Forty-eight (62%) treated HCV and two-thirds prescribed a PI. Barriers to prescription included unfamiliarity (six of 16), lack of allied health (five of 16) and few suitable patients (seven of 16). Pretreatment liver biopsy was performed by 33% (16 of 48) and 69% (33 of 48) used noninvasive measures. Rapid virological response was measured in 83% (40 of 48). Referral patterns changed in 46% (22 of 48) of physicians who treated HCV. All respondents who did not treat HCV referred patients for consideration, with 90% (26 of 29) made to hepatologists. CONCLUSIONS: Chronic liver disease comprised <25% of practice in the majority of surveyed respondents. Among those who treated HCV, one-third have not prescribed a PI. Barriers to prescription and referral pattern changes are noted by those currently treating patients with HCV infection.

When is CT-based postoperative seroma most useful to plan partial breast radiotherapy? Evaluation of clinical factors affecting seroma volume and clarity.

PURPOSE: To evaluate the effect of the time from surgery and other clinical factors on seroma volume and clarity and establish the optimal time to use the computed tomography (CT)-based seroma to plan partial breast irradiation (PBI). METHODS AND MATERIALS: A total of 205 women with early-stage breast cancer underwent planning CT after breast-conserving surgery. One radiation oncologist contoured the seroma volume and scored the seroma clarity, using a standardized Seroma Clarity Score scale, from 0 (not detectable) to 5 (clearest). Univariate and multivariate analyses were performed to evaluate the associations between the seroma characteristics and the interval from surgery and other clinical factors. RESULTS: The mean interval from surgery to CT was 84 days (standard deviation 59). During postoperative Weeks 3-8, the mean seroma volume decreased from 47 to 30 cm(3), stabilized during Weeks 9-14 (mean 21) and was involuted beyond 14 weeks (mean 9 cm(3)). The mean seroma clarity score was 3.4 at Weeks 3-8, 2.5 at Weeks 9-14, and 1.6 after 14 weeks. The seroma clarity was greater in patients aged >or=70 years. The seroma volume and clarity correlated significantly with the volume of excised breast tissue but not with the maximal tumor diameter, surgical re-excision, or chemotherapy use. CONCLUSION: The optimal time to obtain the planning CT scan for PBI is within 8 weeks after surgery. During Weeks 9-14, the seroma might remain adequately defined in some patients; however, after 14 weeks, alternate strategies are needed to identify the PBI target. The lack of correlation between the seroma volume and tumor size suggests that the CT-based seroma should not be the sole guide for PBI target volume definition.
