Appendageal tumours localized to the head, face and neck region continue to fascinate and confuse the dermatologists. We report a case of multiple apocrine hidrocystomas on the face of a 35 year-old woman. Good cosmetic result was obtained with excision followed by cauterization. 相似文献

White piedra is a rare fungal infection of hair and is reported to be all the more rare on scalp. Trichosporon inkin is usually associated with white piedra of pubic hair. We report a case of white piedra of scalp hair caused by T. inkin. This is the first case reported from India and the fifth case reported worldwide. A 50-year-old Muslim female presented with white knots over scalp hair. Diagnosis of Trichosporon was made by examining KOH mounts of epilated hair and Lactophenol Cotton Blue preparations of the growth in culture. Automated mini-API test (for biochemical profiles) and Electronmicroscopy studies (for cell wall structures) helped in identification of the species. Mini-API test was also positive for Cryptococcus curvatus which could be due to similarity in biochemical and physiological properties of the two species. Absence of C. curvatus on culture further supports this view. Topical antifungal therapy resulted in clinical clearance within 2 months. Higher incidence of scalp white piedra is observed in Muslim females; contributing factor being the custom of using a veil, leading to higher humidity and limited sunlight exposure. 相似文献

Background:
A combination of topical retinoid and antibacterial therapy is often advocated for acne to enhance therapeutic efficacy.Aims:
A preliminary study to evaluate the efficacy and tolerability of a topical fixed combination of nadifloxacin (1%) and adapalene (0.1%) in the treatment of mild to moderate acne in Indian patients.Materials and Methods:
This was an open-labeled, phase 3 non-randomized, non-comparative study conducted at five centers (Ahmedabad, Nagpur, Thane, Bangalore, and Mumbai) across India. Of 119 enrolled patients with mild to moderate acne, 117 patients were evaluated at the end of the study for efficacy parameters. A fixed combination of nadifloxacin (1%) and adapalene (0.1%) topical gel was applied at the affected area once at night for a period of 8 weeks. Reduction in the total, inflammatory and non-inflammatory lesion counts from the baseline, investigator global assessment (IGA) and reduction in the severity of acne as per combined acne severity classification were the primary efficacy variables measured at 2 weeks, 4 weeks, and 8 weeks.Results:
Overall, 98.3% patients showed a statistically significant progressive reduction in non-inflammatory lesion counts, inflammatory lesion counts, and total lesion counts over the study duration. By the end of 8 weeks, 75% of the patients had their global assessment scores approaching to normal healthy skin score. The adverse events were mild to moderate in severity.Conclusion:
This preliminary study shows that a fixed combination of 1% nadifloxacin and 0.1% adapalene topical gel could be an effective and well-tolerated option for the treatment of mild to moderate acne vulgaris. However, further well-controlled, randomized and comparative evaluation of this combination is necessary. 相似文献8.

Melatonin is a chronobiotic hormone, which can regulate human diseases like cancer, atherosclerosis, respiratory disorders, and microbial infections by regulating redox system. Melatonin exhibits innate immunomodulation by communicating with immune system and influencing neutrophils to fight infections and inflammation. However, sustaining redox homeostasis and reactive oxygen species (ROS) generation in neutrophils are critical during chemotaxis, oxidative burst, phagocytosis, and neutrophil extracellular trap (NET) formation. Therefore, endogenous antioxidant glutathione (GSH) redox cycle is highly vital in regulating neutrophil functions. Reduced intracellular GSH levels and glutathione reductase (GR) activity in the neutrophils during clinical conditions like autoimmune disorders, neurological disorders, diabetes, and microbial infections lead to dysfunctional neutrophils. Therefore, we hypothesized that redox modulators like melatonin can protect neutrophil health and functions under GSH and GR activity–deficient conditions. We demonstrate the dual role of melatonin, wherein it protects neutrophils from oxidative stress-induced apoptosis by reducing ROS generation; in contrast, it restores neutrophil functions like phagocytosis, degranulation, and NETosis in GSH and GR activity–deficient neutrophils by regulating ROS levels both in vitro and in vivo. Melatonin mitigates LPS-induced neutrophil dysfunctions by rejuvenating GSH redox system, specifically GR activity by acting as a parallel redox system. Our results indicate that melatonin could be a potential auxiliary therapy to treat immune dysfunction and microbial infections, including virus, under chronic disease conditions by restoring neutrophil functions. Further, melatonin could be a promising immune system booster to fight unprecedented pandemics like the current COVID-19. However, further studies are indispensable to address the clinical usage of melatonin. 相似文献

Abstract: We report a 25‐day‐old boy who was referred to our dermatology unit for evaluation of extensive annular erythematous lesions on his body. We initially considered the differential diagnoses of candidiasis and neonatal lupus erythematosus but investigations revealed the case as tinea corporis due to a relatively uncommon causative agent, Microsporum gypseum. To the best of our knowledge it is the first case of extensive neonatal dermatophytoses caused by this organism. The possible causes and the role of steroids in producing the clinical picture in our patient are discussed. 相似文献

Pyrimethamine is an antimalarial drug and a known teratogenic agent. With this drug, positive and negative results have been reported by various investigators in in vivo and in vitro genotoxicity/mutagenicity assays. In this investigation the genotoxic effects of pyrimethamine (PY) were tested in mice in vivo systems, using the bone marrow micronucleus test (MNT) and the transplacental MN test (TMNT). PY at the highest dose (40 mg/kg) induced statistically significant MN in bone marrow cells at 24 and 48 h. In the transplacental MN test, PY did not induce significant MN in fetal liver or in maternal bone marrow. Teratogenesis Carcinog. Mutagen. 20:65-71, 2000. 相似文献
