Background: Melasma is an acquired cutaneous disorder characterized by hyperpigmentation of the face predominantly affecting the areas exposed to direct sun light. The triple combination cream, i.e., a mid-potency corticosteroid (Fluocinolone acetonide 0.01%), a retinoid (Tretinoin 0.05%), and Hydroquinone 4% is one of the widely used topical medicament for melasma treatment world over. Tranexamic acid is another agent found to be effective in melasma treatment when used topically, intra-lesionally or orally. This study has been conducted to compare mean decrease in Melasma Area Severity Index (MASI) score when tranexamic acid is combined with triple combination cream versus triple combination cream alone for melasma treatment.
Methods: A randomized controlled trial was conducted in a tertiary care hospital of Pakistan. Sixty-three patients of melasma who met the inclusion criteria and gave written informed consent for the study were enrolled. These patients were randomly divided into 2 treatment groups. Group A was given triple combination cream and oral tranxemic acid while Group B was given triple combination cream for duration of 8 weeks. Severity of melasma was assessed by MASI, which was calculated at baseline and at the end of week 8. Mean decrease in MASI score was calculated in both groups and statistically analysed employing SPSS 20.
Results: Sixty patients, 30 in both groups, completed the study. Study participants were predominantly female (81.67%), with mean age of 30.46±6.24 years in group A while 31.90±4.53 in group B. No statistically significant difference was noted in both treatment groups for mean decrease in the MASI score (6.4933±4.38358 in group A compared to 5.7833±5.04251 in the group B; p-value 0.56).
Conclusions: The addition of oral tranexamic acid did not contribute significantly in decrease in MASI score when used in combination with topical triple regimen. It may have a role as an adjuvant to topical triple combination cream.

Objectives: Zimbabwe is endemic for lymphatic filariasis (LF) with 39 districts identified for mass drug administration (MDA) in 2014. The objective of this study was to reassess the current population requiring MDA.
Methods: The LF confirmatory mapping method was used to evaluate the prevalence of circulating filarial antigens (CFA) among school-aged children (9-14 years) in previously endemic districts.

The global incidence of metastatic melanoma with BRAF mutations, characterized by aggressive behavior and poor prognosis, is rising. Recent treatment advances, including immune checkpoint inhibitors (ICI) and targeted therapies (TT) such as BRAF and MEK inhibitors, have significantly enhanced patient outcomes. Although guidelines recommend sequencing strategies, real-world implementation can be influenced by clinical scenarios.

Mixed radiation with different doses induces CCL17 to recruit CD8T cell to exert anti-tumor effects in non-small cell lung cancer.

Department of Radiation Oncology, Affiliated Hospital of Jiangnan University, Wuxi, China.
Background: Different doses of radiotherapy (RT) exert diverse effects on tumor immunity, although the precise irradiation method remains unknown. This study sought to elucidate the influence of combining different doses of RT with immune checkpoint inhibitors (ICIs) on the infiltration of CD8T cells within tumors, thereby augmenting the anti-tumor response.
Methods: Constructing a mouse model featuring bilateral lung cancer tumors subjected to high and low dose irradiation, the analysis of RNA transcriptome sequencing data and immunohistochemical validation for tumors exposed to various dosages guided the selection of the optimal low-dose irradiation scheme.

CD7-targeted chimeric antigen receptor-T (CAR-T) cell therapy has shown great promise in the treatment of relapsed/refractory T-cell acute lymphoblastic leukemia (T-ALL). In this study, we reported a case of a 34-year-old male patient with T-ALL who finally developed multi-line drug resistance and refractoriness after multiple lines of high-intensity chemotherapy. After physician evaluation, this patient received allogeneic hematopoietic stem cell transplantation (allo-HSCT).
