"Tinea capitis caused by Microsporum canis: A case study of three family members in India, a non-endemic region.

INTRODUCTION: Tinea capitis, a common scalp infection primarily affecting children, is caused by keratinophilic dermatophytic fungi, notably Microsporum and Trichophyton species. Microsporum canis, primarily transmitted from cats and dogs to humans, is rarely reported in non-endemic regions like India. We report a cases involving three family members from Delhi, India, diagnosed with tinea capitis caused by Microsporum canis. The index case, a five-year-old boy, contracted the infection through contact with a cat, while his younger brother and sister acquired it through human-to-human transmission within the family. METHODS: Clinical examination, microscopic analysis, and molecular identification techniques confirmed the diagnosis. Antifungal susceptibility testing revealed sensitivity to itraconazole and terbinafine but resistance to griseofulvin. RESULTS: Treatment with oral terbinafine and topical ketoconazole cream led to successful outcomes for all three patients. Molecular typing confirmed clonality of the isolates, indicating human-to-human transmission. CONCLUSION: This case study underscores the significance of considering atypical sources of infection and human-to-human transmission in the diagnosis and management of tinea capitis caused by Microsporum canis in non-endemic regions. It emphasizes the necessity of thorough contact history assessment and appropriate antifungal therapy for effective control of the infection.

A Cross-Sectional Study on Post-Coronavirus Disease (COVID-19) Hair Loss at a Tertiary Care Hospital.

INTRODUCTION: Severe acute respiratory virus syndrome coronavirus 2 (SARS-CoV-2) was responsible for coronavirus disease (COVID-19) pandemic. As patients recovered from COVID-19 infection, hair loss was increasingly observed as a distressing symptom. METHODS: This was a cross-sectional study of patients with post COVID-19 hair loss between July to December 2021 at a tertiary care center. Detailed history, clinical examination, trichoscopy and biochemical tests were performed and recorded. COVID-19 disease severity was assessed based on duration of COVID-19 infection and place of management. RESULTS: The study included 120 patients with a mean age of 39.6 years. The majority of the patients were females treated at home and had COVID-19 infection for >2 weeks. The mean visual analog scale (VAS) score for stress was 5.25. Vitamin D deficiency was present in 56.7% and low ferritin in 30% of cases. The mean time of onset of hair loss post COVID-19 was 49 days. Patients mainly presented with diffuse hair loss. Trichodynia was present in 15.8% of cases. The degree of hair loss was severe in 55.8% of the subjects. Positive hair pull test was seen in 65% of patients. Most common trichoscopic features included single hair follicles (81.7%) and vellus hair >10% (60%). CONCLUSIONS: The mean time of onset of hair loss post COVID-19 infection was less than 2 months. Majority patients had diffuse pattern and severe degree of hair loss. Trichoscopy can aid in unmasking co-existing patterned hair loss in patients presenting clinically with diffuse hair loss.

Application of CL Detect™ rapid test for diagnosis and liposomal amphotericin B for treatment of cutaneous leishmaniasis: A retrospective analysis from a tertiary care centre in a non-endemic area in India.

Background Increasing urbanisation has led to the occurrence of cutaneous leishmaniasis (CL) in new areas, which was otherwise localised to endemic areas. Healthcare workers should be made aware of this entity to ensure clinical suspicion of CL and investigations needed to confirm CL. The article describes patients seen at a tertiary hospital in Delhi. Aims To establish the utility of the CL Detect Rapid test as a diagnostic tool and the efficacy of Liposomal Amphotericin B (LAmB) for the complete cure of CL patients. Methods Data of patients of CL (n = 16) was retrospectively analysed concerning diagnosis and treatment. Diagnosis rested on histopathology, real-time PCR, and CL Detect Rapid Test. Speciation of the parasite was based on the Internal transcribed spacer-I gene. Patients were treated with LAmB (i.v., 5 mg/kg up to three doses, five days apart). Results A positivity of 81.3% (95%CI, 54.4-96) was observed for CL Detect Rapid test in comparison with 100% (95%CI, 79.4-100.0) for real-time PCR and 43.8% (95%CI, 19.8-70.1) for microscopy/histopathological examination. L. tropica was the infective species in all cases. All the patients treated with LAmB responded to treatment, and 9/10 patients demonstrated complete regression of lesions, while one was lost to follow-up. Limitations It is a retrospective study, and the data includes only confirmed cases of CL at a single centre. Conclusion This study highlights the utility of CL Detect as a promising diagnostic tool and the efficacy of LAmB for the complete cure of CL.

Trends of syphilis seroprevalence at a tertiary care center in New Delhi, India: A 10-year analysis.

Objectives: Syphilis has been called the great mimicker or the great imitator due to its myriad of clinical presentations. Despite strenuous concerted efforts toward the elimination of syphilis, it still remains a goal to be achieved. During recent years, many different trends of syphilis have been reported from around the globe. Methods: A retrospective observational clinico-investigative study was carried out to analyze the 10-year trends of syphilis at one of the largest public sector hospitals in India. Results and Conclusion: Both venereal disease research laboratory and Treponema pallidum Hemagglutination assay positivity rates showed a significant declining trend from 2007 to 2016, reflecting the success of the National Sexually Transmitted Infection Prevention and Control Program.

Nevus of Ota: Combination Treatment with Q-Switched Neodymium-Doped Yttrium Aluminum Garnet Laser and Fractional CO2 Laser.

Background: Nevus of Ota is a facial dermal melanocytic hamartoma occurring more commonly in Asians. The mainstay of treatment is 1064-nm Q-Switched neodymium-doped yttrium aluminum garnet (Nd:YAG) laser, which has shown variable results in pigmented skin. Objective: The aim of this study was to determine whether Q-Switched Nd:YAG laser treatment combined with fractional CO2 laser is more efficacious than Q-Switched Nd:YAG laser alone. Materials and Methods: This was a prospective study with 81 patients. The patients were randomly divided into two groups. Group 1 received 1064-nm Q-Switched Nd:YAG laser alone and group 2 in addition received a fractional CO2 laser as well. Both groups received six sittings at monthly intervals. The treatment response was documented with physician global assessment (PGA) and patient's treatment satisfaction on Wong-Baker Facial Pain Scale (WBFPS). Dermoscopic evaluation was done to see subsurface pigment clearance. Results: In the combination group, 25% of patients had more than 50% improvement as compared with 5.71% in group 1. To achieve a mean PGA score of 1.4, it took six sessions for group 1 versus only four for group 2. Dermoscopic evaluation showed faster pigment clearance in the combination group. Conclusion: Combining two lasers shows statistically significant faster and greater degree of improvement as compared with Q-Switched Nd:YAG laser monotherapy in nevus of Ota.

Real-time Intraoperative Dermoscopic Monitoring of Common Acquired Melanocytic Nevi Following Shave Excision.

Background: The treatment of common acquired melanocytic nevus (CAMN) is mostly desired for cosmetic purposes due to which a number of "faster and less traumatizing" techniques have been developed. The major cause of recurrence is incomplete removal; there is a need for early detection of any residual pigment. Aims and Objectives: This study aimed to assess the recurrence of common acquired melanocytic nevi and whether dermoscopy can be used as a noninvasive tool for the assessment of residual pigment following shave excision. Materials and Methods: A total of 100 patients of age more than 18 years with clinical features suggestive of common acquired melanocytic nevi were enrolled in the study. The nevi were assessed clinically and dermoscopically and, if found benign, were excised using shave excision. The specimen obtained was sent for histopathological examination. Dermoscopy was used immediately after shave excision for observing any residual pigment and, if present, was removed using radiofrequency current. The patients were followed up at 6 and 12 weeks for recurrence. Results: On histopathology, 87% nevi were intradermal, 8% were compound, and 5% had insufficient tissue for diagnosis, which were clinically diagnosed as junctional nevi. Dermoscopy immediately after shave excision helped in detecting residual pigment in 91% nevi, which was immediately ablated with radiofrequency, thus decreasing the risk of recurrences. Recurrences were seen in 33% nevi and all were intradermal with the presence of hair in the majority (66.67%) of them. Conclusion: Shave excision is a minimally invasive and easily performed procedure. Dermsocopy can be used for assessing residual pigment after shave excision and thus reducing the risk of recurrences. On combining shave excision with radiofrequency ablation and assessing by dermoscopy, majority of patients were satisfied with the cosmetic results. Using dermoscope for follow-up helps in early recognition of recurrence and thus appropriate treatment can be provided at the earliest.
