Chromoblastomycosis (CBM) is a chronic, progressive, cutaneous and subcutaneous fungal infection following the traumatic implantation of certain dematiaceous fungi. The disease has worldwide prevalence with predominant cases reported from humid tropical and subtropical regions of America, Asia, and Africa. Diagnosis is often delayed or misdirected either due to poor degree of clinical suspicions or clinical simulation of dermatological conditions. The infection is not uncommon in India and several case reports from the sub-Himalayan belt and western and eastern coasts of India have been published; however, very few have reviewed the cases. We reviewed 169 cases published in English literature from India during 1957 through May 2016, including 2 recent cases from our institute. A tremendous increase in the number of reported cases was noticed since 2012, since which, more than 50% of the cases had been published. A majority of the patients (74.1%) were involved in various agricultural activities directly or indirectly. The mean age at presentation was 43.3 years ± 16.0, with male to female ratio of 4.2:1. The duration of disease at the time of presentation varied from 20 days to 35 years. Any history of trauma was recalled only in 33.8% of the studied cases. The lower extremity was the most common site afflicted, followed by the upper extremity. The culture was positive in 80.3% of the cases with Fonsecaea pedrosoi, isolated as the most common fungal pathogen, followed by Cladophialophora carrionii. Although all the commercially available antifungals were prescribed in these cases, itraconazole and terbinafine were the most commonly used, either alone or in combination with other drugs/physical methods, with variable degrees of outcome. Combinations of different treatment modalities (chemotherapy and physical methods) yielded a cure rate of 86.3%. CBM is refractory to treatment and no single antifungal agent or regimen has demonstrated satisfactory results. Increased awareness with early clinical suspicion of the disease and adequate therapy are necessary to improve the outcome. However, depending upon the causative agent, disease severity, and the choice of antifungals, variable outcomes can be observed.
In spite of having been formulated nearly two decades back, there is as yet no consensus on the validity of the clinically popular self-medication hypothesis (SMH) of substance use disorders in patients with dual diagnosis. SMH broadly proposes that patients use substances in a non-random fashion so that the psychopharmacologic characteristics of particular substances are used to alleviate a variety of psychiatric symptoms and emotional distress. In order to test the SMH empirically, it was broken down to five sub-hypotheses, which were tested in a group of dual-diagnosis schizophrenia (DDS) patients vis-à-vis a group of only-schizophrenia (S) patients (n = 22 each). The DDS group scored lower than the S group regarding general and some specific psychopathology. The DDS patients ascribed reasons for substance use more often for hedonistic pursuit but also for reduction in symptoms and distress. There was a trend for alcohol to be used more for self-medication purposes compared to opioids and cannabis. The perceived effects of these three substances were significantly different on several symptom/distress dimensions. Finally, there was some degree of "match" between symptom-oriented reasons for use of substances and the effect that was perceived. All of this evidence provides a consistent but modest support for the SMH for "some patients, some substances, and some symptoms." The implications are discussed.
Background The epidemiology of the Coronavirus-disease associated mucormycosis (CAM) syndemic is poorly elucidated. We aimed to identify risk factors that may explain the burden of cases and help develop preventive strategies. Methods We performed a case-control study comparing cases diagnosed with CAM and taking controls as recovered COVID 19 patients who did not develop mucormycosis. Information on comorbidities, glycemic control, and practices related to COVID-19 prevention and treatment was recorded. Multivariate regression analysis was used to identify the independent predictors. Results A total of 352 patients (152 cases and 200 controls) diagnosed with COVID-19 during April-May 2021 were included. In the CAM group, symptoms of mucormycosis began a mean of 18.9 (SD 9.1) days after onset of COVID-19, and predominantly rhino-sinus and orbital involvement was present. All, but one, CAM cases had conventional risk factors of diabetes and steroid use. On multivariable regression, increased odds of CAM were associated with the presence of diabetes (adjusted OR 3.5, 95%CI 1.1-11), use of systemic steroids (aOR 7.7,95% CI 2.4-24.7), prolonged use of cloth and surgical masks (vs. no mask, aOR 6.9, 95%CI 1.5-33.1), and repeated nasopharyngeal swab testing during the COVID-19 illness (aOR 1.6,95% CI 1.2-2.2). Zinc therapy was found to be protective (aOR 0.05, 95%CI 0.01-0.19). Notably, the requirement of oxygen supplementation or hospitalization did not affect the risk of CAM. Conclusion Judicious use of steroids and stringent glycemic control are vital to preventing mucormycosis. Use of clean masks, preference for N95 masks if available, and minimizing swab testing after the diagnosis of COVID-19 may further reduce the incidence of CAM.
COVID-19-Associated Mucormycosis Outbreak, India M ucormycosis is an invasive fungal infection associated with high death rates. Poorly controlled diabetes mellitus, organ transplantation, hematological malignancies, and immunosuppression are the known predisposing factors for mucormycosis (1). During the second wave of the COVID-19 pandemic (April-June 2021), a large number of cases of COVID-19-associated mucormycosis (CAM) were reported globally, primarily in India (2-5). The explanation for this outbreak of CAM in India remains unclear. Diabetes mellitus and glucocorticoids (used for treating COVID-19) have been identified as risk factors for CAM (2,6). Other factors proposed in the pathogenesis of CAM include altered iron metabolism, the severity of COVID-19, and immune dysfunction resulting from COVID-19 (e.g., lymphopenia and others) (7,8).A high burden of Mucorales (in the hospital and outdoor environments) has been reported in India
Sporotrichosis is endemic in the Sub-Himalayan belt, which ranges from the northern to the north-eastern Indian subcontinent. Similar to many parts of the developing world, sporotrichosis is commonly recognized clinically in this region however consolidated epidemiological data is lacking. We report epidemiological, clinical and microbiological data from a hundred culture positive cases of sporotrichosis. Out of 305 clinically suspicious cases of sporotrichosis, a total of 100 isolates were identified as Sporothrix schenckii species complex ( S. schenckii ) on culture. Out of the culture proven cases 71% of the cases presented with lymphocutaneous type of lesions while 28% had fixed localized type and 1% had disseminated sporotrichosis. Presentation with lesions on hands was most frequently seen in 32% with arm (23%) and face (21%) in that sequence. The male to female ratio was 1∶1.27. Age ranged from 1 ½ years to 88 years. Mean age was 43.25 years. Disease was predominantly seen in the fourth to sixth decade of life with 58% cases between 31 and 60 years of age. Since the first report from the region there has been a steady rise in the number of cases of sporotrichosis. Seasonal trends reveal that most of the patients visited for consultation in the beginning of the year between March and April. This is the first study, from the most endemic region of the Sub-Himalayan belt, to delve into epidemiological and clinical details of such a large number of culture proven cases over a period of more than eighteen years which would help in the understanding of the local disease pattern of sporotrichosis.
