Background: There is a wide variation in the incidence of childhood tumors world wide. The relative incidence of childhood tumors in developing countries is increasing and might add significantly to the high childhood morbidity and mortality caused by infectious diseases. There is need to determine the incidence of childhood cancer in different centers of the country and contribute to the National cancer register.
Objective: The aim of this study is to determine the burden and patterns of childhood tumour in our environment.
Methods: A retrospective review of histologically diagnosed cases of childhood tumours seen from January 2000 to 2007 from the records of the Department of Morbid Anatomy of the Lagos University Teaching Hospital (LUTH), Nigeria was carried out. All the cases were analyzed for age and gender distribution as well as histological types.
Results: Malignant tumours constituted 30.50% of the tumours of which retinoblastoma is the most common. The most common benign tumour was fibroadenoma accounting for 36.2% of all benign tumours. The female to male ratio for malignant and benign tumours are 1:1 and 1:1.3 respectively. The peak age incidence was 11 - 15 years for benign and 1 - 5 for malignant tumours.
Conclusion: The study showed decrease in the annual incidence of childhood tumours in Lagos. There was however no difference in the pattern when compared with other centers in Nigeria and in other African countries.

Associations between interpersonal and community-level violence experiences and HIV outcomes: implications for violence screening in Ryan White Clinics.

Violence experience, interpersonal and community-level, is commonly reported by people living with HIV (PLWH). Understanding the impact of the various forms of violence on HIV outcomes is critical for prioritizing violence screening and support resources in care settings. From February 2021 to December 2022, among 285 PLWH purposively sampled to attain diversity by gender, race/ethnicity, and HIV care retention status in Atlanta, Georgia, we examined interpersonal and community violence experiences and proxy measures of violence (post-traumatic stress disorder (PTSD), anxiety, depression) and their associations with HIV outcomes (engagement and retention in care and HIV viral suppression) using multivariable analysis.

Menarche is an important period in a female's life; its time of onset may depend on various factors and could correlate with the development of diseases in adulthood. Our study aims to investigate the relationship between body mass index and age at onset of menarche; METHODS: We used a unique standardized national dataset on adolescent girls participating in the Italian Health Behaviour in School-aged Children Study. Two independent nationally representative survey datasets: one on 15-year-olds (n = 6505, year 2017/2018) and one on 11-year-olds (n = 6548, year 2013/2014) were analysed.

Rationale: Tobacco smoking is a well-established risk factor for idiopathic pulmonary fibrosis (IPF), yet the influence of early-life tobacco exposure on future IPF risk remains poorly understood.
Objectives: To test the hypothesis that early-life tobacco exposure may elevate the risk of developing IPF, with this effect potentially modified by genetic susceptibility to IPF and mediated through accelerated biological aging.
Methods: Using data from over 430,000 participants in the UK Biobank, we performed a prospective cohort study to examine the associations of maternal smoking around birth and age of smoking initiation with IPF risk.

Introduction: A main feature of CDH is lung hypoplasia and the related presentation of pulmonary hypertension and cardiac dysfunction. Multiple factors influence pulmonary status after CDH: degree of hypoplasia, ventilator-induced injury, altered growth and development of pulmonary structures, reduced diaphragm function and chest wall abnormalities. The evolution of pulmonary sequela in this population is still unclear.
