Subcutaneous Phaeohyphomycosis in a Renal Transplant Patient by a Rare Fungus Medicopsis romeroi.

Medicopsis romeroi is a dematiaceous fungus that rarely causes subcutaneous phaeohyphomycosis. Here, we report a subcutaneous phaeohyphomycosis caused by a rare dematiaceous fungus, M. romeroi, in a 56-year-old male renal transplant patient. The patient was admitted for graft dysfunction and was found to have painless swelling over the anterior aspect of the right knee, which was aspirated twice within 40 days. Broad septate hyphae (determined by microscopy) and growth of phaeoid in a culture were observed in both the specimens. No sporulation was observed in the slide culture. Swelling recurred even after treatment with voriconazole, so the lesion was surgically excised. Genotypically, the isolate was identified as M. romeroi in both specimens. He was discharged on voriconazole. During a 6-month follow-up, no relapse was noticed. Phaeohyphomycosis caused by M. romeroi is rare, with only a few cases reported in India. Laboratory diagnosis of Medicopsis by conventional methods is challenging. Medicopsis species should be considered one of the etiological agents for subcutaneous phaeohyphomycosis. Molecular methods should be used for the identification of unusual pathogens.

Infectious hepatitis: A 3-year retrospective study at a tertiary care hospital in India.

Context: Acute viral hepatitis (AVH) is predominantly caused by hepatitis A virus (HAV) and hepatitis E virus (HEV), the prevalence of which varies in different geographical regions. Aims: This study aimed to determine the prevalence of HAV and HEV infections in patients with AVH, the rate of HAV-HEV co-infection and the prevalence of HEV infection among pregnant women with hepatitis. Settings and Design: It was a retrospective observational study conducted over 3 years from January 2015 to December 2017, after obtaining clearance from the institutional ethics committee. Subjects and Methods: A total of 675 serum samples were collected from patients with a clinical diagnosis of AVH, between January 2015 and December 2017. The study population included outdoor and hospitalised patients between 3 and 70 years of age who presented with signs and symptoms of hepatitis. The presence of IgM anti-HAV and IgM anti-HEV antibodies in serum were assessed by enzyme-linked immunosorbent assay. Statistical Analysis Used: Chi-square test. Results: The prevalence of HAV, HEV and HAV-HEV co-infection was found to be 6.96%, 9.63% and 2.07%, respectively. Among males, this was 7.3%, 8.8% and 2.6%, respectively and in females 6.7%, 10.2% and 1.7%, respectively. However, these differences in the prevalence rates were of no statistical significance. The prevalence of HEV infection in pregnant women with hepatitis was 9.4%. HAV and HEV infections showed a seasonal trend with predominance during summer and rainy seasons (May to September). Conclusions: A higher seroprevalence of HEV as compared to HAV together with a co-infection rate of 2.07% mandates screening for HEV in all suspected cases of acute hepatitis, particularly pregnant women in whom the outcomes of HEV infection are poor. Health and civic authorities should make necessary efforts to counter epidemic or outbreak situations, thus reducing morbidity, mortality and economic burden.

Actinomycetes canaliculitis complicating congenital nasolacrimal duct obstruction in an infant.

Actinomyces israelii is a Gram-positive anaerobic organism commonly associated with canaliculitis in adults. Pediatric canaliculitis is relatively rare, especially in infancy. We report the case of an 11-month-old boy who presented with co-existing canaliculitis and congenital nasolacrimal obstruction. The presenting signs included epiphora, discharge, conjunctival congestion, and matting of lashes. On examination, punctual pouting, regurgitation, and yellow canaliculiths were noted. A punctoplasty and canalicular curettage were performed along with nasolacrimal probing. Microbiological tests confirmed the organisms to be A. israelii. We discuss the clinical features and management of Actinomyces-associated canaliculitis and review the available literature on pediatric canaliculitis.

Fulminant intracranial hypertension due to cryptococcal meningitis in a child with nephrotic syndrome.

Cryptococcus neoformans has a worldwide distribution. Meningoencephalitis is the most common manifestation of cryptococcosis. The outcome of a patient with cryptococcal infection depends on the immune status of the host. Patients with nephrotic syndrome are particularly susceptible to cryptococcal infection not only due to innate changes in their immune system but also because of the immunosuppressive agents used in the treatment. We report an 8-year-old boy with nephrotic syndrome, who developed cryptococcal meningitis and died of fulminant intracranial hypertension.

Two cases of scalp white piedra caused by Trichosporon ovoides.

White piedra is a superficial fungal infection of the hair shaft, caused by Trichosporon beigelii . We report two cases of white piedra presenting as brown palpable nodules along the hair shaft with a fragility of scalp hairs. T. beigelii was demonstrated in hair culture of both the patients and T. ovoides as a species was confirmed on carbohydrate assimilation test. The first patient responded to oral itraconazole and topical ketoconazole, with a decrease in the palpability of nodules and fragility of scalp hairs at the end of two months.
