Concomitant dengue fever in Varicella zoster infection - A rare presentation.

Varicella zoster infection is one of the self-limiting viral infections during childhood and dengue fever is an endemic infection in Malaysia, which commonly occurs in the form of nonspecific febrile illness at the initial stage. It is rare for the two viral infections to occur simultaneously. A case of dengue fever without warning sign in a five-year old girl was reported, with early symptoms of fever and vesicular rashes. She was clinically diagnosed with varicella zoster infection during the first visit. Surprisingly, she remained febrile even on day six of illness despite no new vesicular lesions on her skin. Due to suspicion of another infection, follow-up investigation was done and revealed isolated thrombocytopenia. This finding was confirmed with positive NS1Ag. A case of rare dengue fever concomitant with varicella zoster infection was reported.

Comparison the effect of 3 point valgus stress knee support and lateral wedge insoles in medial compartment knee osteoarthritis.

BACKGROUND: There are many opinions and controversies regard the effect of lateral wedge insoles and valgus stress 3point knee braces in treatment of medial compartment knee osteoarthritis (OA). In this study we compared the effect of lateral wedge insoles and 3 point knee supports in treatment of medial compartment knee OA. METHOD: Sixty patients (35-65 years), with knee pain and genu varum and moderate to severe medial compartment DJD were divided into three groups. The first group received a custom molded 3 point valgus stress knee support. Lateral wedge insoles were applied for the second group and the third group served as control. All groups were followed for 9 months according to pain severity, walking distance, and radiologic changes. RESULTS: Pain reduced significantly in both lateral wedge and knee brace groups compared to control group with more significant reduction in the brace group. The walking distance was significantly longer only in the brace group. There was more pronounced effect of brace in patients with severe DJD in walking distance compared to moderate DJD, but not in severity of pain. CONCLUSION: Three point valgus stress knee support had more significant effect on pain reduction, walking distance and also radiologic improvement of patients with moderate to severe medial compartment DJD compared to lateral wedge insoles and could even reverse radiologic findings.

Sympathetic skin response (SSR) in Crohn disease: a pilot study.

Peripheral neuropathy is one of the most frequently reported neurological extra-intestinal manifestations of the Crohn disease. Former studies have showed sympathetic neuropathy as early manifestation of CD by physical tests. The aim of this study is to examine sympathetic neuropathy in CD by using sympathetic skin response (SSR). We performed SSR on 6 Patients (4 male, 2 female) that were diagnosed as CD. Their age was between 26 till 68 years with the mean of (43.3 +/- 17.1) years. The duration of their disease was at least 4 years (mean: 9.0 +/- 8.4) and none of the patients had any symptoms or signs related to autonomic nervous system dysfunction. Hand and foot latencies in CD patients were prolonged relative to controls and the difference of hand latencies was statistically significant. Two patients demonstrated total abnormal results. In conclusion, there is some sub-clinical sympathetic dysfunction in CD patient. This suggests that SSR can be useful in detecting early autonomic changes in these patients.

The diagnostic value of ultrasonography in patients with electrophysiologicaly confirmed carpal tunnel syndrome.

OBJECTIVE: To evaluate the diagnostic value of ultrasonography in patients with electrophysiologically confirmed carpal tunnel syndrome. DESIGN: A prospective ultrasonographic study of 70 wrists with electrophysiologically confirmed carpal tunnel syndrome and of 80 normal wrists. Receiver-operating-characteristics curves for the ultrasonographic measurements of median nerve were plotted to identify the most optimal cutoff values. RESULTS: The ultrasonographic measurements of median nerves were found to be increased significantly in patients with carpal tunnel syndrome when compared with controls, particularly in terms of cross-sectional area (P <0.001). According to receiver-operating-characteristics curve results, the most optimal cutoff value for the cross-sectional area of the median nerve was obtained at the level of middle carpal tunnel, which was 9.3 mm2, with a sensitivity of 80% and specificity of 77.5%. CONCLUSION: Ultrasonographic examination of the median nerve seems to be a promising method in the diagnosis of carpal tunnel syndrome, evaluating the morphologic changes of the median nerve in patients with clinical signs and symptoms. Further studies with wider series are needed to confirm our preliminary results.
