ABSTRACT
Background: Prompt and accurate diagnosis of extra-pulmonary tuberculosis (TB) is highly challenging. Current conventional techniques lack sensitivity and are time-consuming. Here, we report our experience with multiplex polymerase chain reaction (MPCR) using two targets namely IS6110 and protein antigen b in the diagnosis of extra-pulmonary TB. Materials and Methods: A total of 150 patients of extra-pulmonary TB visiting tertiary care center in north India between September 2008 and December 2009 were included in the study. Sixty-six biopsy samples and 84 were body fluids from these patients were subjected for microscopy (Ziehl-Neelsen), culture on LJ medium and for Multiplex PCR using IS6110 and Protein b antigen. Results: Smear positivity was noted in 11 samples (7.33%), and LJ culture yielded Mycobacterium tuberculosis in 8 biopsies and 9 body fluids with overall positivity of 11.3%. The multi-targeted PCR could detect M. tuberculosis in a total of 112 samples. Of 112 positive samples, only Protein b band was detected in 7 samples and only IS6110 was detected in 5 samples. Overall Protein b, PCR could detect 71.33% of the cases, whereas IS6110 was positive in 66.6% of the cases. Overall the sensitivities of microscopy, culture, IS6110 PCR, Protein b PCR and MPCR were 7.33%, 11.3%, 66.67%, 71.3% and 74.6%, respectively. Thus by using more than two targets the sensitivity increased from 66.67% of IS6110 to 74.6% in MPCR. Conclusion: Multiplex polymerase chain reaction using IS6110 and Protein b antigen is a highly sensitive and specific tool in the diagnosis of pauci-bacillary conditions like extra-pulmonary TB.

OBJECTIVE: To study the efficacy of splinting and oral steroids in the management of carpal tunnel syndrome (CTS). DESIGN: Prospective, randomized, open-label, clinical and electrophysiological study with 3-month follow-up. MATERIALS AND METHODS: Forty patients with CTS were randomly divided into splint group (N-20), wearing splint in neutral position for 4 weeks; and steroid group (N-20), who received oral prednisolone 20 mg/day for 2 weeks followed by 10 mg/day for 2 weeks. Clinical and electrophysiological evaluations were done at baseline and at 1-month and 3-month follow-up. Independent 't' test and paired 't' test were used for statistical analysis. OUTCOME MEASURES: Primary outcome measure was the symptom severity score and functional status score. Secondary outcome measures were median nerve sensory and motor distal latency and conduction velocity. RESULTS: At the end of 3 months, statistically significant improvement was seen in symptom severity score and functional status score in both groups (P<0.001). Median nerve sensory distal latency and conduction velocity also improved significantly in both the groups at 3 months. Improvement in motor distal latency was significant (P=0.001) at 3 months in steroid group, while insignificant improvement (P=0.139) was observed in splint group. On comparing the clinical and electrophysiological improvement between the two groups, except for the functional status score, there was no significant difference at 3-month follow-up. Improvement in functional status score was significantly more in steroid group (P=0.03). CONCLUSION: There was significant improvement in both groups, clinically as well as electrophysiologically, at 3 months. On comparing the efficacy of the two treatment methods, except for the functional status score, there was no significant difference between the two groups.

X-linked adrenoleukodystrophy (XALD) is an inherited disorder of peroxisomal metabolism. Atypical presentations have been occasionally reported in literature. However, extrapyramidal and cerebellar manifestations are distinctly rare. We report a patient of X-linked adrenoleukodystrophy with cranial and cervical dystonia and neurological presentation resembling spinocerebellar degeneration followed by a brief review of relevant literature.
