Scedosporium Infection in Recipients of Kidney Transplants from Deceased Near-Drowning Donor.

Scedosporium aurianticum infection developed in 2 recipients of kidney transplants in India, acquired from the same deceased near-drowning donor. Given the substantial risk for death associated with Scedosporium infection among solid-organ transplant recipients, safety protocols for organ transplantation from nearly drowned donors should be thoroughly revaluated and refined.

Antifungal Susceptibility Profile of Clinical and Environmental Isolates of Aspergillus Species From a Tertiary Care Center in North India.

INTRODUCTION: Aspergillus species are ubiquitously found in the environment worldwide and are important causative agents for infection. Drug resistance among Aspergillus species is emerging, hence the present study was undertaken to look for antifungal susceptibility profiles of clinical and environmental isolates of Aspergillus species. MATERIALS AND METHODS: During the period from January 2018 to June 2019, a total of 102 Aspergillus isolates (40 clinical, 40 hospital, and 22 community environment) were tested for antifungal susceptibility testing for determination of minimum inhibitory concentration (MIC)/minimum effective concentration (MEC) as per Clinical and Laboratory Standards Institute (CLSI) M38-A3 method for itraconazole, voriconazole, amphotericin B, and caspofungin. RESULTS: Out of these 102 Aspergillus isolates, A. flavus was the most common species present. Aspergillus species were found to have low MIC values to azoles such as itraconazole and voriconazole except for one clinical isolate, which showed a MIC value of 2 µg/ml to voriconazole. Two isolates were non-wild-type for amphotericin B, but all isolates were wild-type for caspofungin. CONCLUSION: Antifungal susceptibility testing among clinical Aspergillus isolates and environmental surveillance studies in view of emerging drug resistance should be undertaken at a larger scale.

Polymicrobial infection presenting as non-clostridial gas gangrene in a non-diabetic trauma patient. A case report and review of literature.

BACKGROUND: Clostridium species are known to be the primary causative organism of gas gangrene. Non-clostridial gas gangrene (NCGG) is another rare necrotizing entity often associated with an underlying disease, particularly diabetes mellitus, and has a high mortality rate. CASE REPORT: A 16-year-old, immunocompetent male was referred to us after four days, following a roadside accident, with a degloving injury over the thigh and knee along with fractures around the knee. Although clinico-radiologically suspicious of gas gangrene, the initial smear report was negative for any Gram-positive bacilli. On the same day, he underwent aggressive debridement with an external fixator spanning the knee to salvage the limb. On post-operative day one, due to deteriorating general clinical condition and a strong clinical suspicion of gas gangrene, he underwent above-knee amputation (open stump) after discussion with microbiologists and physicians. RESULTS: Polymicrobial non-clostridial infection was seen in culture reports taken serially at different stages of management. The latest follow-up showed a healed amputation stump following split skin grafting. CONCLUSION: Although rare, polymicrobial infections can present as non-clostridial gas gangrene even in an immunocompetent patient. A high index of clinical suspicion with a multi-disciplinary approach helps in early decision-making to avoid a devastating outcome.

Species Distribution and Antifungal Susceptibility Profile of Dermatophytes from a Tertiary Care Centre in North India.

Objective Dermatophytoses, one of the most ancient diseases, is becoming a menace in recent times. This has made the knowledge of antifungal susceptibility a priority in today's times. Material and Methods This is a prospective study conducted over 18 months including all dermatophytes isolated during the period. Dermatophytes were identified by routine phenotypic methods. Antifungal susceptibility testing was performed for griseofulvin, terbinafine, and itraconazole as per the Clinical Laboratory Standard Institute M38 A2, and minimum inhibitory concentrations (MICs) were read after 5 days. Results Patient details and associated risk factors were recorded. Fixed dose combinations with steroids were associated with 79.3% (46 out of 58) of patients with dermatophytosis of skin. Among the 72 dermatophytes isolated during the study period, 58 (80.5%) were isolated from skin scrapings and 14 (19.4%) from nail samples. Tinea corporis with cruris was the most common presentation. The most common dermatophyte isolated from skin scrapings was Trichophyton mentagrophytes complex (70.6%, 41 out of 58), while from nail samples it was Trichophyton rubrum complex (78.57%, 11 out of 14). Based on the MIC 50 and MIC 90 results, itraconazole showed the lowest MICs, followed by terbinafine and then griseofulvin. Conclusion With the changing epidemiology of species distribution and antifungal resistance, there is a need for continuous surveillance of these parameters of dermatophytes.

An Experience with Delamanid in an XDR TB Case - Case Report.

INTRODUCTION: Tuberculosis is an endemic infection and a serious public health problem in India. India constitutes one-fourth of the global TB population. The emerging drug resistance is a major threat to global tuberculosis care and control. CASE REPORT: We present a case of newly diagnosed microbiologically confirmed, extremely drugresistant primary pulmonary tuberculosis which was treated with Delamanid and was found to be cured of tuberculosis. DISCUSSION: Delamanid is a new anti-tubercular drug, which is thought to primarily inhibit the synthesis of methoxy-mycolic, and keto-mycolic acid, which are components of the mycobacterial cell wall. In our patient who was a newly diagnosed case of MDR-TB converted to XDR-TB in little course of time and we were successful in treating him with Delamanid therapy. His sputum culture conversion was achieved in 20 days. Even though the patient did not tolerate well because of the side effects of the drug, still he became microbiologically negative for tuberculosis. CONCLUSION: Delamanid fulfills many target criteria for new TB drugs and may be particularly useful for the treatment of MDR-TB. It can be administered orally and its bactericidal properties make it suitable in regimens designed to shorten treatment duration. Clinical efficacy data, while limited, are reassuring.

Aspergillus candidus eumycetoma with review of literature.

OBJECTIVE: Mycetoma is a slowly progressive, chronic granulomatous infection of skin and subcutaneous tissues with involvement of underlying fasciae and bones, usually affecting extremities. In India, among mycetoma, the eumycetoma constitutes about 35% of cases. Hereby, we report the first case of eumycetoma caused by uncommon fungus, Aspergillus candidus. CASE REPORT: A 61 year old female presented to the Department of Dermatology with history of swelling of right foot associated with multiple firm nodules of approx. 1.5 × 1.5 cm each over dorsum of foot with discharging sinus containing white color granules. Biopsy of lesion on right foot on direct KOH examination revealed septate hyphae. Histopathology examination showed a histiocytic granuloma with fungal elements. Culture on Sabouraud Dextrose Agar grew white mycelial colonies which were identified to be Aspergillus species phenotypically. Genetic sequencing using Internal transcribed spacer gene, beta tubulin gene and Calmodulin gene was done and the isolate was identified to be Aspergillus candidus. Lesion was excised and patient was started on itraconazole. CONCLUSION: Timely identification and starting of antifungal treatment can help in reducing morbidity due to eumycetoma to a large extent. As newer and newer species of fungi are emerging as significant causative agents of human infections, it is pertinent to report such findings from epidemiological point of view.

Nosocomial Outbreak of SARS-CoV-2 in a Non-COVID Zone of a Tertiary Care Hospital of North India: Need to Upgrade Infection Control Practices.

BACKGROUND: Hospital acquired infections are preventable cause for morbidity and mortality worldwide. In the current pandemic era proper implementation of infection control measures can prevent the spread of such infections including SARS-CoV 2. The study was done to identified the source and reason for spread of COVID-19 infection and devise recommendations to halt the progress of infection in a non-COVID area. METHODS: An outbreak in a non-COVID area of a tertiary care hospital was investigated by the infection control team along with the epidemiologist when they were notified about the rising cases of COVID-19 from Advanced Trauma Center's (ATC) disaster ward. The time, place and person distribution of the cases were studied. Recommendations based on gaps identified were developed onsite and implemented to control the outbreak. RESULTS: The outbreak lasted from 19th December 2020 to 12th January 2021, affecting 34 people (25 patients and 9 health care workers). The attack rate was 9.2%. We identified the causes of current outbreak as compromises in infection prevention measures, high bed patient ratio, irregularities in the ventilation system, overcrowding by patient attendants and communication gaps between nursing officers and doctors. Measures required to control the outbreak were implemented and no cases were reported for 2 weeks following the last positive case. CONCLUSION: Non-COVID areas of hospitals are also at risk of nosocomial outbreaks of SARS-CoV 2 and therefore strict infection prevention measures those designated to COVID areas should be followed in non-COVID zones also to prevent such outbreaks.
