Background Unilateral naevoid telangiectasia (UNT) is a rare disease with only sporadic cases reported. The pathogenesis remains elusive and especially in paediatric patients, effective and safe treatment is still uncertain. Objectives The purpose of this study was to summarise the clinical characteristics of UNT, explore the possible pathogenesis and evaluate the efficacy and safety of pulsed dye laser (PDL) therapy. Materials and Methods The epidemiological data, clinical manifestations, laboratory tests and pathological features of paediatric patients with UNT were retrospectively reviewed. PDL treatment was done on some of the patients. Clinical documents and patient images before and after treatment were assessed to evaluate efficacy and adverse events. Results Most of the cases (9/11) presented with unilateral lesions. The laboratory results of all the 11 cases were normal. Histological examination in six cases revealed multiple, dilated veins in the reticular dermis. Vascular endothelial growth factor (VEGF) staining was positive, whereas oestrogen receptor staining was negative. Nine cases were treated with PDL which was shown to be effective and safe. Conclusion UNT has typical clinical manifestations. The pathogenesis of this disease could be linked to VEGF; however, more research and confirmation are needed. PDL is an effective and safe treatment for UNT.

Background Mycoplasma genitalium is implicated in genitourinary disorders in both men and women as a sexually transmitted infection (STI). This study aimed to ascertain the prevalence of M. genitalium and identify associated risk factors among women. Aim To investigate the prevalence of M. genitalium and identify various risk-factors associated with M. genitalium infection in women attending the clinic in Western Cameroon. Methods A cross-sectional study was conducted in hospitals from five districts of Western Cameroon on sexually active and non-menstruating women attending for antenatal, prenuptial and contraception consultations,between January 2020 and July 2020. Endocervical swabs (n = 680) were collected, and M. genitalium was detected using real-time PCR targeting the MgPa and pdhD genes. Results A total of 680 women, characterised by a mean age of 27.4 ± 7.5 years, were included in this study. The overall prevalence of the M. genitalium infection was 5.2%. Bivariate analysis revealed that having more than one sexual partner was independently associated with three times higher odds of prevalent M. genitalium infection (OR 2.9, 95% CI: 1.03-8.56). Limitation Cross-sectional design limits exploring temporal relationships with other STIs. Freezing specimens for a year until PCR testing may have compromised detection rates of M. genitalium. Conclusion This study contributes valuable data to the limited understanding of M. genitalium epidemiology. The findings may aid in the formulation of national clinical standards for testing and screening strategies, emphasising the importance of addressing associated risk factors in the targeted population.

Background There is scant data on basal cell carcinoma (BCC) in Indian patients. This retrospective study was conducted to explore epidemiology, risk factors, clinical and pathological aspects, and long-term treatment outcomes of BCC in a cohort of North Indian patients. Methods Data about patients registered in the dermatosurgery clinic between 01 January 2017 and 31 December 2022 with a confirmed diagnosis of BCC was collected. Results Among the 83 patients, 56.6% were females, and the median age was 62 years (6-85 years). Most patients (81.9%) had a single BCC lesion, resulting in a total of 126 assessed lesions. The median size of BCC at presentation was 1.90 cm, with nodular BCC being the most common histopathological subtype (39.7%). Head and neck region involvement was observed in 82.5% of patients, with the malar region, nose, and periorbital region being the most commonly affected sites. Pigmentation was clinically evident in 45.2% of cases. Surgical excision was the primary treatment modality (71.1% of patients). The median follow-up duration was 40 months (6-57 months). Recurrence occurred in five patients, with a longer disease-free survival period observed in the surgically treated group (55.58 ± 0.98 months) compared to patients treated with medical or destructive therapies (43.6 ± 3.482 months) (p = 0.003). Conclusion The data from this hospital-based study indicated a slight predilection for females among North Indian patients with BCC, with most cases occurring during their seventh decade of life. The condition commonly occurred on sun-exposed areas such as the malar region and nose, with a high percentage of pigmented lesions. Recurrence following surgical excision was rare, and overall treatment outcomes were favourable.

Background Gamma-glutamyl transferase (GGT) has been associated with coronary heart disease, diabetes mellitus, and hypertension, but its association with psoriasis has not yet been elucidated. Aims We conducted this study to determine the association between the risk of psoriasis and the serum GGT. Methods We conducted a nationwide population-based study. A total of 9,939,350 people met the enrolment criteria. The study population was classified into four groups based on GGT levels and the risk of psoriasis was calculated for each group. Results The incidence rates of psoriasis per 1,000 person-years were 2.96105 and 3.68577 in the lowest and highest GGT groups, respectively. After adjusting for age, sex, income, diabetes mellitus, hypertension, dyslipidemia, smoking, alcohol intake, exercise, and body mass index, the highest GGT group showed a significantly increased risk of developing psoriasis (hazard ratio: 1.057, 95% confidence interval: 1.044-1.07). This risk of psoriasis was significantly higher among the old age group (hazard ratio: 1.162, 95% confidence interval: 1.128-1.197) and women (hazard ratio: 1.14, 95% confidence interval: 1.117-1.164). Limitations The limitations of this study included the retrospective design, International Classification of Diseases code-based diagnosis, small hazard ratio, and non-availability of data on covariates. Conclusion The GGT level was found to be an independent risk factor for developing psoriasis.

The efficacy and safety of combining H1 antihistamines (AHs) for treating urticaria are currently unclear. This scoping review aims to provide a comprehensive overview of the evidence regarding the efficacy and safety of H1 AH combinations in the management of urticaria up to May 2023. The search encompassed databases such as PubMed, Web of Science, the Cochrane Central Register of Controlled Trials, and the China Biological Medicine Database. The inclusion criteria comprised randomised controlled trials (RCTs), non-randomised trials (NRTs), case reports, and case series focusing on urticaria treatment. Initially screening 12,887 studies, this review ultimately selected 109 studies involving 11,435 patients. These studies documented 43 different combination treatments across 11 types of urticaria. In comparison to monotherapy, combination therapy exhibited superior efficacy in 94 studies that reported treatment efficacy. Regarding adverse drug reactions (ADRs), 67 studies disclosed ADR incidences, with combination therapy showing lower ADR rates in 32 studies. Additionally, 7 studies reported similar ADR rates between combination therapy and monotherapy with AHs. Common ADRs included symptoms such as drowsiness, nausea, fatigue, dry mouth, dizziness, and headache, while less frequent side effects encompassed hypotension, otitis media, polyuria, rhinorrhoea, abnormal liver function, and rash. ADR rates ranged from 0% to 21% in the treatment group, and from 0.5% to 75% in the control group. Importantly, patients generally tolerated these ADRs well, with symptoms resolving upon discontinuation of treatment. The study's findings suggest that combining AHs leads to enhanced efficacy and reduced safety risks compared to monotherapy in the context of urticaria treatment. These results advocate for considering combination therapy as a viable option in clinical practice, especially for chronic urticaria cases. Nonetheless, caution is advised, and close monitoring for potential ADRs is crucial during treatment.
