Drug use among adolescents in Ilorin, Nigeria.

The types and frequency of drug use among 1200 students aged 10-19 years was investigated and a prevalence rate of 40.1% found; currently used drugs included mild stimulants such as kolanut and coffee 294 (26.2%), alcohol 164 (14.5%), sniffing agents 80 (7.2%), amphetamine and ephedrine 66 (6.7%), cigarette 54 (4.8%), heroin 45 (4%) cocaine 40 (3.6%) and cannabis 38 (3.4%). Multiple drug use was found among the students, with the abuse of cannabis, cocaine and heroin being significant among those who smoked cigarette (P<0.001). The relative risk (RR) for cannabis use when cigarette was smoked was 37.4 (24.1-57.8); RR for cigarette smoking when alcohol was used, 6.8, while RR for cocaine abuse when cigarette was used, 21.8 (13.9-34.5) and 52.8 (29.2-95.5) when cannabis was used. It is therefore concluded that the use of the licit and "socially" acceptable drugs may pave the way for the abuse of illicit ones.

Sexual activity among adolescents in Ilorin, Kwara State, Nigeria.

With the aid of a self-administered questionnaire, sexual activity was investigated among 1,200 students aged 10-19 years. Two hundred and sixty-four (23.7%) respondents indicated they were sexually active. The mean age at first intercourse was 11.3 years (SD=5.8 years), while the average number of sex partner was 2-3. Multiple sexual partners were found in 99 (69.2%) of the males and in 16 (32.7%) of the females (P < 0.05). Males were more sexually active, 189 (32.8%) compared with 73 (13.7%) females (P=0.000001; RR=2.4 (1.88-3.05). Two hundred and fifty-three (23.4%) ofthose respondents who claimed to be highly religious had sexual intercourse compared with 7 (50%) of those who claimed not to be religious (P=0.02; PR=0.47 (0.27-0.80). Those whose parents lived together were less likely to be sexually active. 184 (21.2%) versus 47 (34.8%) (P=0.005). It is therefore concluded that our adolescents especially males remain sexually active. It also demonstrates the dramatic lowering of age at first intercourse. Family supervision and level of religious activity were recognized as factors that have significant impact on sexual activity. Preventive efforts must therefore focus on these issues with the active involvement of the Pediatrician, parents and religious leaders.

Russell-Silver Syndrome in a Nigerian infant with intrauterine growth retardation.

Russell-Silver Syndrome (RSS) is a rare cause of pre-natal dwarfism, associated with recognizable dysmorphic features and limb asymmetry. The propositus was a term infant of unrelated Nigerian parents, whose 35-year-old mother had peri-conceptual haloperidol for schizophrenia. Anthropometric values suggested severe prenatal stunting in a term infant with asymmetric "head sparing" intrauterine growth retardation (IUGR). A syndromic consideration of Russell-Silver dwarfism was subsequently predicated on the distinctive dysmorphic craniofacial features of a triangular facial profile with a broad forehead and hypoplastic mandible, right upper and lower limb rhizomelia, clinodactyly of the little fingers, micro-penis, and (unilateral) cryptochidism. Routine care of a small-for-gestational-age infant was pursued, but postnatal growth remained slow (despite adequate caloric provision) until a parent-pressured discharge at 4 weeks. His subsequent demise was said to have occurred "suddenly" 2 weeks post-discharge. Despite the limitations posed by the local paucity of modern investigative tools for genetic disorders, the current case report underscores the diagnostic reality of RSS in a non-white African population. While emphasizing the need for a high index of diagnostic suspicion for congenital malformations and syndromic causes of IUGR in the African sub-region, we suspect a possible etiologic association of haloperidol embryopathy with RSS in the current case. The characteristic features, differential diagnoses, etiologic postulates/current cytogenetic and molecular genetic findings of RSS are fully reviewed in the discussion.

Packed red cell volume pattern in Nigerian preterm babies.

Weekly packed red cell volume (PCV) was estimated in 57 Nigerian preterm babies whose gestational ages were less than 34 weeks. Babies were excluded if they required exchange blood transfusion or had major congenital malformations. The mean (SD) PCV at birth was 54.6% (8.3). The nadir of the PCV drop was at the 10th-11th week of life. The PCV at the nadir was 29.3% (SD 2.9). The rate of drop in the PCV was most rapid in the 1st 2 weeks (velocity -4.6% per week), but by the 7th week this had decreased to -1.2% per week. The findings indicate a slower rate of postnatal fall in PCV among Nigerian preterms. We recommend that PCV and systemic signs of anaemia be monitored for the 1st 12 weeks of life.

Evaluation of neonates with risk for infection/suspected sepsis: is routine lumbar puncture necessary in the first 72 hours of life?

To determine whether lumbar puncture is necessary in the evaluation of neonates with risk for infection or suspected sepsis in the first 72 hours of life, we reviewed the laboratory and medical records of 506 infants who had lumbar punctures between January 1988 and December 1990. Neonates < 72 hours of age accounted for 52% of all lumbar punctures, but no case of meningitis. This led to a policy shift from routinely performing lumbar punctures to reserving them for infants with signs of severe sepsis (i.e. lethargy, hypothermia, hypotonia, poor perfusion or apnoea), specific neurological signs or clinical deterioration. This new policy was monitored prospectively from July 1991 to December 1993. Three times fewer procedures were performed in neonates < 72 hours, and there was no diagnosed or missed case of meningitis. Given that meningitis is rare within the first 72 hours of life and the yield of lumbar puncture virtually zero, we recommend that lumbar punctures be reserved for selected infants.

Tuberculous laryngitis in a Nigerian child.

A 12.5-year-old Nigerian child presented with progressively worsening hoarseness of 9 months duration, without overt features of chronic ill health. Superficial discrete cervical adenitis, radiological evidence of miliary tuberculosis and hilar adenopathy were identified on admission. The laryngoscopic findings comprised fully mobile but 'beefy' red, oedematous vocal cords and interarytenoid region. The diagnosis of tuberculous laryngitis was made on the basis of the laryngoscopic, radiological and clinical improvement that followed antituberculous therapy. The possible pathogeneses of tuberculous laryngitis are discussed. We emphasize the importance of considering tuberculous laryngitis in a child with persistent hoarseness.

Chloramphenicol-resistant Haemophilus influenzae meningitis in young urban Nigerian children.

In a developing country like Nigeria, the unusual emergence of Haemophilus influenzae type b, resistant to cost-effective antimicrobials, is of serious concern. We report three cases of H. influenzae type b meningitis in young Nigerian children in whom clinical and bacteriological features of resistance to chloramphenicol were identified. One of the cases had concomitant resistance to ampicillin (multiple-drug resistance). Significant anaemia was an associated feature in two cases, one of whom had a recent measles infection. All three cases were malnourished. The possible mechanisms of antimicrobial resistance in H. influenzae infections are highlighted while the need for periodic surveillance of antibiotic resistance profiles in resource-poor countries is emphasized. The potential value of prophylactic measures like H. influenzae type b conjugate immunization is discussed.
