Context: The abuse of psychoactive substances which is one of the most important global public health problems begins in adolescence. Adolescents usually start by abusing the gateway substances. They suffer social, economic, physical, and legal consequences on account of use of substances, and this is very worrisome because of the increasing prevalence of use. Aims: The aim was to identify the characteristics of adolescents that use gateway substances. This knowledge shall be utilized in preventive programs. Settings and Design: Cross-sectional study with secondary school adolescents as participants. Subjects and Methods: Multistage sampling technique was used to select 492 respondents and the questionnaire consisted of characteristics of the adolescents, their families and schools and the alcohol, tobacco, cannabis, and stimulant use sections of the World Health Organisation questionnaire for student drug use surveys. Statistical Analysis Used: The data were analyzed using the Statistical Package for Social Sciences, and Chi-square statistics was used. Results: Having a friend who uses substance was significantly associated with tobacco, alcohol, cannabis, and caffeine use while being a male, having a family member that uses substance were significantly associated with tobacco, alcohol, and caffeine use. Older age, lack of satisfaction with the relationship with the teacher and polygamous family background were significantly associated with tobacco use. And finally, lack of satisfaction with the relationship with parents/guardians and having parents or guardians who are not religious were significantly associated with alcohol use. Conclusion: A comprehensive approach is needed to prevent the use of substances; this should target individuals, schools, families, and religious institutions.

Background: Hydrocephalus among children is an important medical problem in view of its neurological sequelae in the growing child. This situation is compounded by the acute shortage of neurosurgeons in third world countries like Nigeria; hence, the need for its early detection and proper management. Objective: Evaluation of the ultrasound (US) appearances in children under 5 years of age presenting with clinical signs of raised intracranial pressure suggestive of hydrocephalus. Patients and Methods: A retrospective review of transfontanelle US scans done in 64 children (39 boys and 25 girls) attending the Department of Radiology, Usmanu Danfodiyo University Teaching Hospital, Sokoto, Nigeria over a period of 2 years was carried out. The patients had a mean age of 5.0 ± 4.6 months (range: 1–60 months) at the time of their US examination. Some of the clinical indications for US scan included: Congenital hydrocephalus, encephalocele, meningomyelocele, and meningitis. All scans were performed through the anterior fontanelle using SIUI Apogee 800 PLUS scanner with a curvilinear probe using multi-frequency transducer of 2–5 MHz. Results: Fifty-two patients (81.3%) had hydrocephalus of congenital origin. Eleven cases (17.2%) had postmeningitic hydrocephalus while only 1 case (1.6%) was posthemorrhagic. Twenty-five patients (48.0%) of the congenital cases were due to cerebral aqueduct stenosis. Eleven (21.2%) of the congenital cases were from obstruction at the exit foramina of Luschka and Magendie resulting in the communicating type of hydrocephalus. Conclusion: Hydrocephalus is a known cause of neurological morbidity among infants in developing countries. Majority of the cases are congenital in origin and most commonly due to cerebral aqueduct stenosis. Transfontanelle US is cheap, affordable, nonhazardous, and more accessible than other imaging modalities. It should serve as the first-line investigation of infants with suspected hydrocephalus for early detection and monitoring of progression to determine those cases that would require shunt operation.

Aims: This study was to evaluate the risk factors associated with tooth wear lesions in patients attending a dental clinic. Context: Tooth wear lesions entail the loss of dental hard tissues in the absence of caries or trauma. They include abrasion, attrition, and erosion. The etiology is often related to habits leading to insidious symptoms with similar presentations in both community and hospital patients. Materials and Methods: This cross-sectional study involved patients attending the outpatient dental clinic of a Nigerian Teaching Hospital over a 3-month period. A semi-structured questionnaire was used to elicit information from the respondents. Results: A total of 152 respondents aged 17–80 years and above, comprising 86 males (56.6%), and 66 females (43.3%) constituted the study population. The Binis were the most represented 34.2%, followed by the Esans 21.1%, while the least represented were the Yorubas (6.6%). The occupations represented in this study include civil servants (30.3%), unskilled workers (23.7%), and non-medical professionals (7.9%). Tooth wear lesions were present in 55.3% of the respondents. Attrition accounted for 29.6%, Abrasion (11.8%), combination of attrition and abrasion (4.6%), and abfraction (2.0%). There was a statistically significant association between tooth wear lesions and age, occupation, sensitivity or pain, tooth cleaning aids, toothbrush texture brushing technique, intake of carbonated beverages, and method of intake. Conclusion: Tooth wear lesions such as attrition and abrasion were prevalent among the respondents in this hospital setting and, therefore, represent an important group of dental problems among this population. It is, therefore, important to direct the appropriate oral health awareness program for the prevention, early detection, and management of these conditions.

Background: Diabetes mellitus is a well-recognized risk factor for stroke. Clinical features, as well as outcome of stroke, difference between diabetic and nondiabetic patients. The objective of this study is to determine the pattern and outcome of management in diabetes-stroke co-morbidity. Materials and Methods: This is a retrospective study where case folders of patient admitted from January 1 to December 31, 2009 with the clinical diagnosis of stroke were traced. A questionnaire was used to extract relevant data from case folders. Results: A total of 115 patients with the clinical diagnosis of stroke were admitted during the study period, but only 88 had complete information out of which 12 (13.6%) had type 2 diabetes. The mean age of the diabetic group (69.67 ± 12.7 years) was found to be significantly higher than that of the nondiabetic group (56.93 ± 16.06 years) (t = 2.615, P = 0.011). Ischemic stroke occurred more frequently in the diabetes stroke the co-morbid group. However, the difference was not statistically significant (χ² =0.079, P = 0.540). Outcome in terms of neurological recovery tended to be poor in the diabetes-stroke co-morbid group as compared to the nondiabetes stroke group (χ² =13.93, P = 0.006). Conclusion: Stroke pattern and outcomes are different in the diabetic patient compared to nondiabetic patient. There is more prevalence of ischemic stroke in the diabetic group of patients often with slow recovery.

Background: There is a paucity of data on the relationship between high-normal blood pressure (BP) and cardiovascular events in Sub-Saharan African countries including Nigeria. This study, therefore, primarily aimed to assess cardiovascular disease (CVD) risk factors among subjects with high-normal BP in comparison with hypertensives and subjects with optimal BP. Materials and Methods: The study was cross-sectional, and comparative conducted at Aminu Kano Teaching Hospital, Kano on eligible subjects aged 18 years and above. Three groups of randomly selected subjects (high-normal, hypertensives and optimal BP) each 100 in number were studied. High-normal BP was defined as systolic BP of 130–139 mmHg and/diastolic BP 85–89 mmHg. CVD risk factors including increased age, male gender, increased body weight, history of excess alcohol intake, cigarette smoking, sedentary lifestyle, family history of premature CVD, hypertension and diabetes mellitus (DM) were assessed and compared between the groups. Results: The most prevalent CVD risk factor was increased body weight found among 58% of subjects with high-normal BP, 63% of hypertensives and 16% of subjects with optimal BP. The study found a significant progressive increase in age, body weight, DM, dyslipidemia and sedentary lifestyle as BP increased across the groups (P < 0.05 for each variable). Conclusions: Subjects with high-normal BP had significantly higher CVD risk factors than those with optimal BP but significantly lower than for hypertensives. Age, body mass index and FBG were independent predictors of high-normal BP.
