Dermatophytosis are fungal infections caused by three genera of fungi that have the unique ability to invade and multiply within keratinized tissue (hair, skin, and nails). Although dermatomycoses are globally distributed, the endemic and most prevalent species of dermatophytosis differ strikingly from one geographic locality to another. Changing trend has been noticed in last few years with dermatophytic infections presenting as chronic, treatment unresponsive and recurrent. Also various microscopic and fungal culture studies have shown shift in identification of causative fungal species in recent years. Numerous studies have been done on the occurrence of dermatophytes in various parts of our country illustrating the range and changing pattern of fungal infection as well as causative fungal species. Total number of 150 patients attending outpatient department of our hospital who were clinically diagnosed as having superficial dermatophytosis were enrolled into the study. Patients were carefully screened as per inclusion and exclusion criteria and then enrolled in the study. Samples were taken from all the patients and examined for KOH direct microscopy and sent for fungal culture on Sabouraud’s Dextrose Agar as well as on Dermtophyte Test Medium. Results were then analyzed using standard statistical methods. Out of total 150 patients, 101 were males and 49 were females. Most common age group was 21-30 years (37.3%). 58 patients (38.7%) showed positivity to KOH microscopy as well as fungal culture. Additionally 25 more samples demonstrated positivity to KOH microscopy (total 83 patients) but negativity to culture, while 9 patient samples were positive to culture but negative to direct microscopy. Predominant fungal species isolated on culture was Trichophyton mentagrophytes (50.7%) while next common species isolated was T. tonsurans (29.9%). No significant association was found between dermatophyte isolate on culture and clinical type. Trichophyton mentagrophytes and Trichophyton tonsurans were the most common species isolated among subjects with Tinea faciei, Tinea cruris and Tinea corporis. The study showed a male preponderance and T. corporis was the commonest clinical type found. Majority of patients were in the 3rd decade and came within a duration of 1 month to 6 months of getting an infection. In patients diagnosed with tinea corporis, tinea cruris, tinea pedis and tinea manuum, T. mentagrophytes was the most predominant species isolated.

<p class="abstract"><strong>Background:</strong> Dermatophytoses are superficial fungal infections which invade and multiply within keratinized tissue. The KOH mount is one of the useful procedures and believed to be more reliable than culture for demonstrating dermatophytes. A few studies in the past have demonstrated the usefulness of alternative methods of sample collection for KOH preparation, but data on sensitivity and specificity of these methods is lacking. The aim of the study was to study the clinic-mycological aspects of dermatophytoses and to compare the efficacy of three different sampling techniques from skin lesions and correlating KOH mount with culture results.</p><p class="abstract"><strong>Methods:</strong> 210 clinically diagnosed patients with dermatophytic infection attending outpatient department of Dermatology of a tertiary care hospital for duration of 2 years (September 2015 to October 2017) were included.

Dermatophytoses refers to superficial fungal infection of keratinized tissues caused by keratinophilic dermatophytes. According to observations worldwide, dermatophytoses are the most common of the superficial fungal infections. It is common in tropics and may present in epidemic proportions in areas with high rates of humidity. This prospective, longitudinal, observational study was conducted at SKHMC, Jaipur for a period of 1 year (April 2018 to March 2019), aiming to ascertain the effectiveness of homoeopathic medicines in the treatment of Tinea corporis and Tinea cruris. In this study, 65 cases of Tinea Infection (33 cases of Tinea cruris & 32 cases of Tinea corporis) were treated with homoeopathic medicines prescribed on the basis of totality of the symptoms. Treatment outcomes were assessed using Clinical Symptom Score, designed for this study & approved by Institutional Ethical Committee. Out of 65 patients, 41 patients (63.1%) got improved; 19 patients (29.2%) were at status quo and 05 patients (07.7%) became worse. Maximum patients were found to be in the age group of 11-40 years (n=50; 76.9%). Males were observed to be affected more as compared to females. Paired t-test was conducted on the Clinical Symptom Scores obtained before and after treatment and the result showed that p value is < 0.05 & value of t (11.623) is greater than the tabulated value in t-table at df = 64 (1.997), which was statistically significant and which also concluded that homoeopathic medicines were effective in treating Tinea corporis and Tinea cruris.

SummaryA 2-year-old female Magyar Viszla was referred with fever, lethargy, polyuria/polydipsia, and suspected systemic cryptococcosis. At presentation increased rectal temperature and enlarged lymph nodes were detected. Main laboratory abnormalities included lymphocytosis, eosinophilia, and mildly reduced urine specific gravity. Abdominal ultrasound was unremarkable. Lymph node cytology revealed mycotic infection. Acremonium species was isolated from urine as well as from a popliteal lymph node by fungal culture. Therapy with itraconazol (10 mg/kg p. o. q 12 h) was initiated based on susceptibility testing, but dosage had to be reduced by half due to adverse effects. Despite treatment, the dog developed progressive azotemia. Four months after initial presentation, the patient showed anorexia, lethargy, weight loss, diarrhea, vomitus, neurological signs, and severe azotemia and was euthanized. Acremonium species are emerging opportunistic mould fungi that can represent a potential threat for immunocompromised humans. In dogs, only two cases of systemic infection with this fungal species have been reported so far. This case highlights the fact that systemic fungal infections should be considered as a differential in cases of fever and lymphadenopathy.

<p class="abstract"><strong>Background:</strong> Skin infections caused by dermatophyte fungi account for 6% of dermatology consultations at our hospital and 3 to 4% worldwide. A variety of antifungal agents are available for topical use. Terbinafine 1% cream is considered the first line topical medication in the treatment of dermatophytosis. Sertaconazole 2% cream is a relatively new drug having antifungal as well as antiflammatory property.

Background: Traditional detection of fungal infections of the skin relies on microscopy techniques or fungal culture. Currently, reflectance confocal microscopy (RCM) has been widely applied to assist the diagnosis of commondermatomycosis with advantages of non-invasiveness, celerity, real time, and repeatability. Materials and Methods: A total of 478 clinically suspected dermatomycosis patients were enrolled in this study including 148 cases of tinea manus and pedis, 188 cases of tinea corporis and cruris and 142 cases of pityriasis versicolor. RCM examination was performed to image the lesions. Aim: This study aimed to summarize the image characteristics of in vivo RCM examination on common dermatomycosis and retrospectively evaluate its accuracy as compared with microscopy results. Furthermore, we attempted to tackle the challenges of RCM diagnosis on common dermatomycosis. Results: Based on RCM images, 231 of 478 (48.3%) patients were detected with hyphae. Among all RCM confirmed cases, 58 out of 148 (39.2%) were tinea manus and pedis, 145 out of 188 (77.1%) were tinea corporis and cruris, and 28 out of 142 (19.7%) were pityriasis versicolor. The remaining patients (51.7%) could not be diagnosed by the dermatologist according to RCM. Hyphae structures were primarily identified during diagnoses of dermatomycosis by RCM. Conclusions: RCM is a novel optical imaging technique that confers high-resolution images of fungi. RCM has certain advantages in the diagnosis of tinea manus and pedis. RCM is not suitable for the diagnosis of pityriasis versicolor.

Abstract Background Bronchoalveolar lavage (BAL) is a widely used procedure in the diagnosis of pneumonia in critically ill and immunocompromised hosts. Fungal smears and cultures are commonly performed on these samples. We evaluated the yield of various fungi, including but not limited to Candida species, Aspergillus species, Penicillium species, isolated from BAL specimens at our institution to determine the yield of this test and its impact on decision making. Methods We identified adult immunocompromised patients who underwent “Bronchoscopy with Immunocompromised Host Protocol (ICH),” which consists of an exhaustive list of diagnostic tests for various pathogenic organisms, over a one year period from January 1, 2017 to December 31, 2017. We reviewed if positive fungal cultures led to a change in management and if this was appropriate. Results 582 patients underwent bronchoscopy with ICH protocol. There were 285/582 (48.9%) positive fungal cultures of which 177 (62%) grew Candida species. The most common species was Candida albicans (142/177, 80%). 53(18%) were Aspergillus species of which Aspergillus fumigatus was the most common (26/53). 16/285 (5.6%) patients underwent intervention based on the results, 14(87.5%) of which were appropriate. 176/177 (99.4%) patients with Candida species in BAL cultures were not treated.10/53 (18. 8%) patients with Aspergillus species in BAL cultures were treated of which 80% were appropriate interventions based on proven/probable invasive fungal infections criteria as were rest of the 6/16 patients with other fungal organisms (Table 4). Patients with Aspergillus species in BAL cultures are 8 times more likely to have an intervention (OR: 8. 7, P = < 0. 0001) while patients with Candida species in BAL cultures are not likely to be intervened upon (OR: 0. 26, P = 0. 0098) (Table 3). Conclusion Although Candida species is commonly isolated in BAL cultures its clinical significance is minimal in the absence of disseminated disease even in immunosuppressed hosts. Evaluating the way that Candida cultures are communicated for respiratory specimens, along with diagnostic stewardship may be a route for antimicrobial stewardship. Consulting ID service early on is essential in assessing the significance of fungal culture data thereby resulting in appropriate changes in management.

Purpose: SARS CoV 2 virus a novel coronavirus, which is a single stranded positive sense RNA virus. It causes severe pneumonia in susceptible individuals. In individuals with predisposing factors, like diabetes, neutropenia, corticosteroids therapy, and etc., the virus causes opportunistic fungal infections. This study aims the correlation between COVID 19 disease and fungal infections. Methodology: The present study includes 202 specimens collected from patients with symptoms suspected of fungal infections. The collected specimens were subjected to direct microscopy and fungal culture. Results: Nasal tissue scrapings were the most common specimen collected followed by sputum. Among the 202 specimens collected, 106 were positive for direct microscopy and 81 were positive for fungal culture. Conclusion: The fungal infections are more common among the patients with comorbidities, and appropriate guidelines should be followed in the management of such infections in order to prevent the morbidity and the mortality.
