Introduction head and neck cancers have essentially been a disease of the elderly but recent studies are beginning to demonstrate their increasing incidence in young people with infections such as human papilloma virus (HPV). This study was carried out to determine the prevalence of high risk Human papilloma virus (hrHPV) related oropharyngeal carcinoma and its prevalent genotypes as well as their strength of association with HIV in adult Nigerian subjects. Methods this was a cross-sectional study of 41 patients with oropharyngeal carcinomas seen over a 2-year period. Patients had incisional and/or excisional biopsy done under anesthesia. A portion of the specimen from which the DNA was extracted was placed in Digene HC2 DNA collection device while the 2 nd portion for histopathological analysis was fixed using 10% Neutral Buffered Formalin (NBF) and embedded in paraffin blocks. Oropharyngeal cancer HPV genotyping was done using HPV genotypes 14 real-tm quant kit (SACACE, Italy). The data was analyzed using SPSS version 23. Results prevalence of HPV was 17.1% with a male to female ratio of 2.7: 1. The identified genotypes were 16, 33, 35 and 52 with 28.6% of patients having more than one genotype. Most of the age groups studied were affected. Squamous cell carcinoma and ameloblastic carcinoma were the cancers associated with HPV. HPV was not identified in the HIV positive patients. Conclusion high-risk human papilloma virus genotypes 16, 33, 35 and 52 are associated with oropharyngeal carcinoma in Nigeria but were not found in HIV patients. This finding provides a strong evidence for the use of the 9-valent prophylactic vaccine for the prevention of oropharyngeal cancer in Nigeria. Public awareness and HPV prevention strategies should reduce significantly the incidence of oropharyngeal carcinomas in our environment.

Introduction asthma is a chronic inflammatory disorder of the airways with over 339 million people affected worldwide. Asthma can impair the quality of life (QoL) in its various bio-psycho-social domains causing poor concentration, poor school performance and impaired daily activities. This study assessed the QoL in asthmatic children aged 7- 17 years. Methods a descriptive cross-sectional study of 46 children with asthma. Relevant bio-data and medical history were documented and the QoL assessment was carried out using the paediatric asthma quality of life questionnaire. Asthma severity and asthma control were defined based on the global initiative for asthma protocol. The data was analysed with IBM SPSS version 22. Results the mean age was 12.4 ± 3.3 years, with a male to female ratio of 1: 1.9. About 61% of the study population were moderately impaired in their QoL and 41.3% had uncontrolled asthma. The mean QoL score was 5.80 with the activity domain and the emotion domain having the lowest mean scores (5.78 ± 1.0 and 5.91 ± 1.2 respectively). There was a significant association between QoL and age, asthma severity, asthma control and social class (p< 0.05) but not Gender. The logistic regression did not identify any of these factors as being predictors of QoL in the children. Conclusion: the study participants had moderately impaired QoL with the 7-10 year-olds more severely affected. The activity and emotion domains are more impaired. Therefore in addition to providing medical intervention, the treatment of children with asthma should include psychological support and counselling.

Introduction primary maxillofacial tumors are uncommon in pediatric patients. When they do occur, the tissue damage caused directly alters facial growth, development as well as psycho-social evolution. This study was carried out to determine the pattern, sociodemographic characteristics and histologic peculiarities of paediatric jaw tumors in our environment. Methods a retrospective hospital-based study where the case notes of children below the age of 14 years who presented with jaw tumors and tumor-like lesions from January 2014 to December 2018 were studied. Results eighty-two patients were studied; patients aged 10-14 years had the highest representation. Mean time of presentation was 8 months with jaw swelling being the commonest presentation (84.1%). Majority of the fathers were in their 4 th decade of life while most of the mothers were in their third decade of life and both parents possessed primary school certificate as their highest level of educational attainment. Fathers were mostly traders, while mothers were mostly full-time housewives. The maxilla and mandible were most commonly affected with the left side showing higher preponderance. Burkitt lymphoma (19 (23.2%)) and adenomatoid odontogenic tumor (14 (17.1%)) were the commonest lesions. When the tumor involved both the maxilla and the mandible, the tumor was most likely malignant. Conclusion in our center, paediatric jaw tumors are commonest in male children with the 10-14 years´ age group most commonly affected. Burkitt lymphoma and adenomatoid odontogenic tumors were the commonest tumors. Early presentation must be encouraged since these tumors if presented early can be successfully treated.
