Biochemical findings in sudden unexpected death in epilepsy: Hospital based case-control study.

PURPOSE: A review study on the biochemistry of epilepsy showed that in epileptic patients, serum glucose and cholesterol concentrations are low, sodium is unaffected, potassium increases, glucose is high and mild hypocalcemia. We have conducted a biochemical study on sudden unexpected death in epilepsy (SUDEP) cases in an attempt to establish the characteristic biochemical values to diagnose these deaths. METHODS: This was a hospital based case-control study done at All India Institute of Medical Sciences, New Delhi for one year. Twenty SUDEP cases and 20 age- and sex-matched controls were included in the study. Femoral blood, cerebrospinal fluid, vitreous humor, and pericardial fluid were biochemically analyzed for sodium, potassium, calcium, glucose, N-acetyl- cysteine activated creatine kinase (CK-NAC) and isoenzyme CK-MB. RESULT: Serum sodium, CK-MB and CK-NAC level was found significantly increased and potassium level was found decreased in SUDEP cases in comparison to non-epileptic deaths. Likewise, in CSF, sodium and CK-NAC was found increased and potassium level was found decreased in SUDEP cases. In vitreous humor, sodium and CK-MB level was found increased and potassium level was found decreased in SUDEP cases in comparison to non-epileptic deaths. In pericardial fluid, sodium, CK-NAC and CK-MB level was found increased and potassium level was found decreased in SUDEP cases in comparison to non-epileptic deaths. CONCLUSION: It concludes that high sodium level and low potassium level could be associated with SUDEP. However, this is a small size study, a larger study is needed to verify the findings. Furthermore, it is difficult to conclude whether these findings are exclusive to SUDEP.

Red Eccrine Chromhidrosis with Review of Literature.

A 22-year-old male presented with reddish discoloration of the vest following perspiration for 6 months. He was a habituated consumer of cranberry juice. The peak absorption on spectrophotometric analysis of the extracted sweat coincided approximately with the peak absorption of diluted distillate of the juice. A diagnosis of eccrine chromhidrosis, probably due to the coloring agents in the juice, was considered. This rare case report emphasizes the possible side effect of the various coloring agents used as food additives.

Granuloma faciale: An unusual diascopic finding.

Granuloma faciale (GF) is a benign, chronic inflammatory disorder, characterized by reddish brown plaques with prominent follicular orificesand telangeictasia, usually occurring over the face. The condition often presents a problem in differential diagnosis. Herein we describe a case of GF with an unusual diascopic finding of an apple jelly appearance on diascopy.

Assessment of efficacy, safety, and tolerability of 4-n-butylresorcinol 0.3% cream: an Indian multicentric study on melasma.

INTRODUCTION: Melasma is one of the commonly reported pigmentory disorders in the Indian population. Numerous therapeutic modalities are available. However, very few have produced complete satisfactory response. 4-n-Butylresorcinol 0.3% cream has recently been introduced in India as a new hypopigmenting agent. It is a resorcinol derivative and acts by inhibiting both tyrosinase and tyrosinase-related protein-1. OBJECTIVE: The available published literatures are with 4-n-butylresorcinol 0.1% cream, and there is paucity of clinical studies with 4-n-butylresorcinol 0.3% cream. Furthermore, considering the fact that Indian skin is more prone to irritation with hypopigmenting agents, our study explores the efficacy, safety, and tolerability of 4-n-butylresorcinol 0.3% cream in Indian subjects with melasma. METHODS: Fifty-two subjects with melasma participated in this open-label, single arm, observational study. All the patients were advised twice daily application of 4-n-butylresorcinol 0.3% cream for 8 weeks over the areas of melasma. Assessment parameters included modified Melasma Area Severity Index (mMASI) score. Digital photographs of all the patients at baseline, week 4, and week 8 were taken. During this 8-week study period, all the adverse events were observed and recorded. RESULTS: All the 52 subjects completed the study. Out of 52 subjects, 90.38% were females. The mean age of patients was 38.5±7.8 years. Mean ± standard error of MASI score measurements showed a significant decrease from baseline score of 14.73±0.59 to 11.09±0.53 after week 4 (P<0.001) and 6.48±0.43 at week 8 (P<0.001). The digital photographs of the study subjects taken at week 4 and week 8 also showed decrease in melasma pigmentation compared to baseline photograph and correlated with the changes in the mMASI score. The treatment was well tolerated by all the study subjects. No adverse reactions were reported throughout the study period. CONCLUSION: Our data suggest that the 4-n-butylresorcinol 0.3% cream is safe, effective, and well tolerated in Indian patients with melasma.

Keloids: an unwanted spontaneity in rubinstein-taybi syndrome.

Rubinstein-Taybi syndrome (RTS) is a rare developmental disorder comprising of mental retardation, unusual facial appearance, broad thumbs, and big toes. It is frequently associated with molecular lesions in the cAMP response element binding protein. Many cutaneous abnormalities are associated with RTS. Multiple spontaneous keloids are some of them. We hereby report a case of this rare syndrome associated with keloids without any preceding trauma.

Gynaecothelia--a common yet ignored sign of multibacillary leprosy in males: a case series with review of literature.

Leprosy is one of the causes of gynaecothelia (enlargement of nipples), however little has been published about this common but usually ignored sign. Herein, we report nine male patients with multibacillary leprosy who had gynaecothelia although only two of them had associated gynaecomastia. None of these patients was aware of gynaecothelia until it was detected by the treating doctor during examination. This study is presented to highlight this common but ignored sign, which may occur specifically in multibacillary leprosy.
