Acanthamoeba species from a post-covid patient with CSF rhinorrhea; a next possible post covid menace? A case report.

A case of Acanthamoeba rhinorrhea in a 32 years female, who was recently recovered from COVID-19 infectionat a tertiary care institute in India. Though, there was no standard treatment protocol for management of amoebic-meningo encephalitis. The patient was managed successfully with combination therapy of amphotericin B and miltefosine. Agents having trophicidal and cysticidal activities are used for treatment of CNS Acanthamoeba infection. COVID 19 infection, steroid therapy anddiabetes mellitus which lead to low immunitywere found to be associated contributing factors.

Diagnostic utility of PCR in detection of clinical cases and carriers of leprosy: A cross sectional study at a tertiary care teaching hospital in central India.

PURPOSE: Since ancient era leprosy is existing across the world. India, Indonesia and Brazil still harbour major proportion of global cases. Child leprosy and Grade II disability indicate delayed diagnosis and persistence of transmission in community. So, this study was conducted with aim to evaluate the diagnostic efficacy of PCR in comparison to SSS (Slit Skin Smear) microscopy for detection of leprosy in early stages in both cases and carriers (contacts). METHODS: A cross sectional observational study was conducted on 100 subjects including 50 clinically diagnosed new cases of leprosy and their 50 contacts. Each group was subjected to SSS (Slit Skin Smear) microscopy and PCR using RLEP gene as target. RESULTS: The overall male: female ratio was 2.44. The Slit Skin smear (SSS) microscopy positivity was 34% (n = 17/50) among cases while it was 0% (n = 0/50) among contacts. The overall positivity for PCR was 42% (n = 42/100) being 66% (n = 33/50) in cases and 18% (n = 9/50) in contacts. About 30% (n = 25/83) of all the microscopically negative subjects were found to be positive by PCR. CONCLUSIONS: PCR was found to be a better diagnostic tool both among cases and their contacts. It should be used for screening contacts for early diagnosis and treatment and thus preventing transmission in community. KEY MESSAGE: To diagnose case and contacts of leprosy in early stages even in very low bacterial density using PCR.

Detection of a Lophomonas, a rare pathogen in Bronchoalveolar lavage.

Lophomonas infection is an emerging parasitic disease-causing respiratory infection. Although common in immunocompromised patient, it has been observed also in some immunocompetent cases. We report the case of a 45-year-old male who presented with productive cough, fever, and chest pain, with marked eosinophilia and cavitary lesion in the X-ray chest. KOH preparation and acid-fast bacilli microscopy of bronchoalveolar lavage (BAL) were negative. Direct microscopic examination of BAL accidentally showed a large number of living Lophomonas species with the movement of flagella. Methylene blue and Giemsa staining showed the plume of flagella and the nucleus. The patient was managed conservatively with metronidazole and get cured. It was concluded that the patient presented with signs and symptoms of pneumonia must be evaluated for rare events also if the patient was not responding with typical management of pneumonia. We reported the first case of this rare entity in Chhattisgarh state in an immunocompetent young Indian male.
