Clinico-epidemiological presentations and management of Nipah virus infection during the outbreak in Kozhikode district, Kerala state, India 2023.

India experienced its sixth Nipah virus (NiV) outbreak in September 2023 in the Kozhikode district of Kerala state. The NiV is primarily transmitted by spillover events from infected bats followed by human-to-human transmission. The clinical specimens were screened using real-time RT-PCR, and positive specimens were further characterized using next-generation sequencing. We describe here an in-depth clinical presentation and management of NiV-confirmed cases and outbreak containment activities. The current outbreak reported a total of six cases with two deaths, with a case fatality ratio of 33.33%. The cases had a mixed presentation of acute respiratory distress syndrome and encephalitis syndrome. Fever was a persistent presentation in all the cases. The Nipah viral RNA was detected in clinical specimens until the post-onset day of illness (POD) 14, with viral load in the range of 1.7-3.3 × 104 viral RNA copies/mL. The genomic analysis showed that the sequences from the current outbreak clustered into the Indian clade similar to the 2018 and 2019 outbreaks. This study highlights the vigilance of the health system to detect and effectively manage the clustering of cases with clinical presentations similar to NiV, which led to early detection and containment activities.

Community Dermatology: Current Status and the Way Forward.

Community health interventions in dermatology have the potential to deliver healthcare to large populations. Such interventions can bridge the gap between increasing demands from vast populations and limited availability and asymmetric geographical distribution of specialist doctors. This narrative review aims to delineate various areas in which community dermatology initiatives are useful, the different approaches used, and the factors which could determine their effectiveness. We did a PubMed search using the search terms, "Community Health Services"[Mesh]) AND "Dermatology"[Mesh]. A further literature search was performed by cross-referencing these articles. In addition to its primary purpose of increasing access, community involvement can augment medical education, foster research, and help to develop more patient-centered clinical guidelines, understand disease trends and influences of the environment on various diseases, and formulate population-centered health policy. Task shifting, development of culture-sensitive and gender-sensitive community healthcare teams, disease-specific patient support groups, and use of advances in technology such as telemedicine are some of the important methods used in community dermatology. Task shifting may be performed at different levels - general practitioners, pharmacists, nurses, and community health workers. Community interventions harness volunteerism among health professionals as well as various stakeholders in the community. Partnering with non-governmental organizations, involving members of the community, and being a part of a long-term public health program help to sustain community interventions. The interventions should adapt to the ethical and cultural norms of the community. Continuity of care, fidelity, and evidence support are crucial for the success of community interventions in dermatology.

Prevalence of eczema among older persons: A population-based cross-sectional study.

Background There are very few population-based studies on the prevalence of eczema among older persons Aims To estimate the prevalence and types of eczema in those aged 65 years or more in the community and to evaluate the effectiveness of community-based interventions for case finding. Methods In the first stage of this cross-sectional survey, trained health workers of a non-governmental organization surveyed the eligible population and identified persons likely to have eczema. In the second stage, dermatologists examined such persons to ascertain the diagnosis. Statistical analysis was done using Epi Info software version 7. Prevalence of eczema was expressed in percentages. Chi-square test was used for comparing the difference in prevalence of eczema in various age groups and sex. Results Health workers identified 98 persons as possible cases of eczema after interviewing 385 older persons in the community. Among them 95 persons were examined by dermatologists and 44 were confirmed to have eczema (diagnostic accuracy of health workers = 46.3%).Point prevalence of eczema was 11.4% (44/385). Prevalence was similar in males and females. It was greater (18.2 %) among persons aged 81 years or more. Asteatotic eczema, gravitational eczema and lichen simplex chronicus were the more common types of eczema. Limitations: Possible underestimation of the prevalence rates due to limited medical knowledge of health workers; limited facilities for examination and investigations at the medical camps and home visits. Conclusion There appears to be a considerable burden of eczema among older persons in the community. A community-based approach involving non-governmental organizations has the potential to identify cases and offer care close to their homes.

The profile of sexually transmitted infections of men who have sex with men: A tertiary care center-based comparative cross-sectional study.

Context: Very few studies have compared the prevalence of sexually transmitted infections (STIs) and risk factors particularly among men who have sex with men (MSM) with the non-MSM group. Aims: (1) To compare the profile of STIs among MSM and non-MSM attending our STI clinic, (2) To identify the risk factors for STIs among MSM. Subjects and Methods: In this comparative cross-sectional study, we analyzed the records of all male attendees of our STI clinic from March 2015 to March 2020 for demographic details, sexual history, clinical examination and laboratory findings. Statistical Analysis Used: Chi-square test and logistic regression were utilized in analysis. Results: The number of both MSM and non-MSM attending the clinic increased over 5 years with a more sharp increase in the number of MSM, after 2017. 68.9% of MSM had their first sexual contact before attaining 20 years of age. The most common STIs were syphilis (53.75%), genital warts (30%) and herpes genitalis (20.62%). Syphilis was the most frequent STI among MSM (48/74, 64.90%) as well as non-MSM (38/86, 44.20%); though its frequency was significantly more among MSM (P < 0.01). Being unmarried (odds ratio [OR] = 3.58, 95% confidence interval [CI] = 1.85-6.93, P < 0.01), having more than two sexual partners (OR = 4.49, 95% CI = 2.12-9.50, P < 0.01), practising peno-oral sex (OR = 4.74, 95% CI = 2.33-9.62, P < 0.01) and peno-anal sex (OR = 19, CI = 8.55-42.38, P < 0.01) were significantly associated with MSM behavior. Conclusions: There was an increasing trend of MSM attending the STI clinic from the year 2017. MSM persons are likely to be younger, unmarried, and have more than two sex partners. The commonest STI among MSM was syphilis.

A multicentric clinical and epidemiological study of chronic and recurrent dermatophytosis in India.

BACKGROUND: There has been an alarming increase in the prevalence of chronic, recurrent and steroid modified dermatophytosis of the glabrous skin in the recent years in India. There is paucity of literature on the magnitude of this major public health problem. OBJECTIVE: To estimate the prevalence of dermatophytosis and clinico-epidemiological features of chronic and recurrent dermatophytosis (CRD) across India and to evaluate the associated risk factors. METHODS: This is a multicentric descriptive cross-sectional study conducted in 13 centres situated across India in two phases during dry and rainy seasons. All consecutive patients presenting with dermatophytosis were screened during the study period of 14 consecutive working days. Patients with CRD of the glabrous skin as per the case definition were included after exclusion of isolated hair and nail infections. Demography, clinical findings and results of potassium hydroxide wet mount were recorded. RESULTS AND CONCLUSION: A total of 41,421 patients were screened, out of which 7174 (17.31%) patients had glabrous dermatophytosis. CRD was observed in 1999 (27.86%) patients with 78.08% and 21.95% of chronic and recurrent dermatophytosis, respectively. Family history was present in 50.03% of patients. History of sharing of fomites was present in 50.37% of them. Synthetic tight clothes were worn by 43.47%, while 50.9% gave history of misuse of topical corticosteroid creams. Multiple site involvement was common (69.58%) with tinea cruris (79.99%) and tinea corporis (75.69%) being the most common clinical types. CRD is associated with sharing of fomites, topical corticosteroid misuse and involvement of multiple sites.

Syphilis in the era of re-emergence: A 6-year retrospective study from a tertiary care center in South India.

Background: During the last several years, we have observed a rise in the number of patients with syphilis in our center. Aims: To find out the trends in the presentation of syphilis to our clinic over a 6-year period and to analyze the clinicoepidemiological features of those patients. Settings and Design: A retrospective chart review. Subjects and Methods: We analyzed the case records of all cases of syphilis registered in our sexually transmitted infection (STI) clinic from October 1, 2012, to September 30, 2018. Syphilis was diagnosed based on clinical or serological evidence. We also evaluated these patients for any concomitant STI, including hepatitis B, hepatitis C, and HIV. Statistical Analysis Used: The data were analyzed using SPSS software (version 20). Chi-square test was done for comparing categorical data, and P < 0.05 was considered statistically significant. Results: During the study period, 215 patients with STI attended our clinic. Of these, 66 (31%) patients had acquired syphilis. Among them, 3 (4.5%) had primary syphilis, 23 (34.8%) had secondary syphilis, and 40 (60.6%) had latent syphilis. Fifteen (22.7%) patients had concomitant HIV infection. A statistically significant rise in the number of cases of syphilis compared with other STIs was noted in the latter half of the study period (P = 0.001). Among the 50 males with acquired syphilis, 29 (58%) were men having sex with men (MSM), including 19 bisexual persons. Among the five antenatal cases, two were detected very late in pregnancy. Conclusions: We observed a marked increase in the number of cases of syphilis during the latter half of the study period. Primary and secondary syphilis were more frequent among MSM, suggesting a need to strengthen targeted intervention programs among them. More rigorous antenatal screening is necessary to prevent congenital syphilis.

Comparison of High Resolution Ultrasonography with Clinical Examination in the Assessment of Peripheral Nerve Involvement in Leprosy.

CONTEXT: Assessment of peripheral nerves in leprosy by clinical methods is subject to considerable inter-observer variability. High resolution ultrasonography (HRUS) can assess peripheral nerves more objectively. AIMS: To compare the findings of peripheral nerve involvement in newly diagnosed cases of leprosy by clinical and sonological methods. SETTINGS AND DESIGN: Cross sectional study in a tertiary care teaching hospital. SUBJECTS AND METHODS: Four pairs of peripheral nerves of 40 newly diagnosed patients with leprosy were examined clinically and by HRUS. STATISTICAL ANALYSIS USED: Agreement between clinical examination and HRUS using kappa statistic; sensitivity; specificity; and predictive values. RESULTS: Of the 320 nerves examined, 71 (22.18%) were abnormal clinically and 63 (19.7%) sonologically. Sonological abnormalities were increased cross sectional area (n = 63; 100%), hypoechogenicity with loss of fascicular architecture (n = 46; 73%) and increased vascularity (n = 35; 55.6%). There was moderate agreement (Cohen's K = 0.59) between clinical and sonological findings. HRUS findings were abnormal in 18 (7.2%) nerves that were clinically normal. HRUS was normal in 26 (36.6%) nerves which were clinically abnormal. Sensitivity of HRUS compared to clinical examination was 63%; specificity 92.7%; positive predictive value 71.4%; and negative predictive value 89.9%. Increased cross sectional area agreed with clinical findings the most. CONCLUSIONS: HRUS has low sensitivity (63%) and high specificity (92.7%) to identify abnormal peripheral nerves in leprosy, compared to clinical examination. It could detect abnormality of some (n = 18, 7.2%) clinically normal nerves, but showed normal findings of some nerves (n = 26, 36.6%), which were considered clinically abnormal.
