    ABSTRACT: To analyse general differences in age, gender, anatomic location of the various histological types of malignant neoplasm involving the oral and maxillofacial region at a tertiary referral centre in Nigeria and to compare this with reports in the literature. Retrospective analysis. A tertiary referral centre in Lagos, Nigeria. All patients with a histological diagnosis of malignancy were included provided the final surgical histology reports as well as the biopsy reports were available for review. Squamous cell carcinoma (SCCA) with a peak age incidence in the 6th decade of life and a male to female ratio of 1.65 to 1 was the most common cancer (42.8%). Males with SCCA (mean = 48.7 years) were relatively younger than females (mean = 58.8 years). Eighteen percent of patients with SCCA were below 40 years at presentation and males were predominantly affected at a ratio of 5.2:1. Majority of the SCCA (75%) were well/moderately well differentiated. However, in patients below 40 years, 45.9% had poorly differentiated SCCA. The Most commonly affected sites for SCCA were the maxillary antrum (36.7%), mandibular gingiva/ alveolus (23.0%) and tongue (12.04%). Patients who presented with antral SCCA were relatively younger (mean = 48.9 years) than those who had SCCA involving the mandibular gingiva/ alveolus (mean = 57.1 years) as well as floor of mouth (mean = 56.3 years). Furthermore, males with antral SCCA were younger than their female counterparts. Similarly, males who had mandibular gingiva/ alveolus SCCA (mean = 48.4 years) were younger than their female counterparts (mean = 62.8 years). Majority of the glandular carcinomas (GLDCAs) arose from minor salivary glands (63.0%). Thirty seven per cent of these patients were below 40 years at presentation. Females who had antral GLDCA (mean = 32.4 years) were relatively younger than their male counterparts (mean = 49 years). Most of the patients who presented with sarcoma were below 40 years (77.4%) and males were younger (22. 8 years) than females (mean = 35.4 years). The proportion of orofacial cancers that is SCCA in Nigerians is relatively low because of a relatively high proportion of GLDCA and Burkitt's lymphoma. A relatively high proportion of patients with SCCA were below 40 years at presentation. They were predominantly males who presented with poorly differentiated tumours.

    ABSTRACT: This is a retrospective analysis on the prognostic factors in the management outcome of clinically and histologically diagnosed carcinoma of larynx seen in Lagos University Teaching Hospital between 1996-1999. Various prognostic factors have been documented as determinants on the probable outcome of carcinoma of the larynx, such as duration of symptoms, smoking, medical status of the patient, degree of differentiation, size and site of tumour and presence of cervical lymph node. Thirty-six patients between 1996-1999 were reviewed, with a male to female ratio of 11:1, and peak age group of occurrence in 50-59 years, majority (86.12%) of which were non-smokers who presented in varied degrees of airway obstruction necessitating pre-treatment tracheostomy in 70% of the patients with more than 50% presenting within 3-6 months of onset of initial symptom. The tumours were staged clinically and histology revealed well differentiated T3 glottic tumour without any clinically palpable neck node in more than 50% of the patients which should predict a better outcome. But the interplay of many prognostic variables like pre-treatment tracheostomy and its attendant complications, supposed biological aggressive tumour in a non-smoker, coupled with treatment biased by patients, high costs of treatment, logistics and poor follow up compliance, resulted in poor outcome of our management.

    ABSTRACT: A prospective study was carried out at the Lagos University Teaching Hospital in Lagos. The aims were to determine the prevalence of otorhinolaryngological disease among patients who were HIV+ and or had clinical AIDS and to correlate the presence of ORL disease with the clinical state of HIV infection. The study was done between October 1998 and September 1999. A total of ninety-eight patients were studied. The age range of the patients was between 15 and 69 years with 83% of them being in the age group of 20-49 years. The results showed that while only 17% of the patients were referred because of ORL diseases, 80% of them actually had O.R.L./head and neck conditions. This difference of proportion is highly significant P = 0.000037. 160.20% of the patients had oral/pharyngeal lesions and 24.5% had identifiable otological disease. Hearing impairment was noted in 30.6% of the patients on pure tone audiometric assessment of which 26.5% were sensorineural. The correlation between O.R.L./head and neck manifestation and the CDC classification of HIV/AIDS infection did not reveal a definite pattern.

    ABSTRACT: An observer blind clinical study was carried out among 64 Nigerian patients with allergic rhinitis to assess the efficacy and tolerance of loratadine a new generation H1 antihistamine. Patients were allotted randomly to receive treatment for 1 week with either loratadine + Vit. C (group A), chlorpheniramine + Vit. C (group B), or Vit. C alone (group C). Assessment was by subjective symptom scoring of three nasal symptoms namely; sneezing, rhinorrhoea and nasal blockage. Difference between pre treatment and post treatment mean symptom scores was used as degree of improvement for statistical analysis and this formed the primary efficacy parameter. Adverse effects namely; anticholinergic effects, gastrointestinal effects and drowsiness were assessed following treatment. The results showed that loratadine was significantly better than Vit. C. alone (P = 0.0002) and chlorpheniramine was also significantly better than Vit. C. alone (P = 0.039). However, loratadine was significantly better than chlorpheniramine P = 0.046. Drowsiness was noted in 19.2% of patients on loratadine compared with 57.1% of patients on chlorpheniramine. lt is concluded that though both loratadine and chlorpheniramine were effective in the relief of symptoms of allergic rhinitis in Nigerian patients, loratadine was significantly more effective with minimal sedating effect.

    ABSTRACT: To identify the career aspirations of interns (house officers) working in two hospitals in Lagos, Nigeria. All house officers working in the Lagos University Teaching Hospital and the General Hospital, Ikeja were invited to participate in a cross sectional survey. A self-administered questionnaire was used to collect data. Specialization choice was evident in 97.1% of the interns while they were undergraduates but this declined to 82.9% on qualifying, though chosen specialties did not vary much between both periods. The preferred specialties were surgery (18.1%), obstetrics and gynaecology (18.1%), paediatrics (9.5%) and dental sciences (10.5%). Doctors who were below the age of 26 years were significantly more likely to want to specialize than others (P=0.017). Furthermore, respondents who had no regrets about selecting medicine as a career were significantly more willing to specialize than others (P=0.013). The major reasons for wanting to specialize were interest in specialty (72.4%), job satisfaction (67.6%) and bright prospects in selected field (54.3%). However, 14.4% no longer wanted to practise medicine while 69% would have liked to leave Nigeria, mainly for the United States of America. Financial considerations were a major reason for both groups. Surgery, obstetrics and gynaecology continue to attract young doctors to the detriment of other specialties. Financial considerations are also a key determinant of with regard to place of future practice.

    ABSTRACT: Three hundred and eight-one cases of head and neck cancers were studied over a 10 year period (1988 - 1998) at the Lagos University Teaching Hospital, Lagos. The aim was to assess the various sites of primary lesion, gender and age distribution and histopathological types. The International Classification of Diagnosis Oncology's (ICDO) 9TH version was used to categorize sites of primary lesion. A yearly incidence of 38 cases was noted with an overall male preponderance. Forty-five percent of the patients with head and neck cancers were in their forth and fifth decades of life. The nasopharynx was the commonest site of primary lesion (16.8%) followed by the nose, paranasal sinuses and middle ear (ICDO - 160) with 13.6%. Laryngeal cancer ranked third accounting for 12.1% of the cases. Other common sites of primary lesion were: the skin (9.2%), the salivary glands (7.6%), the mandible (7.3%) and the thyroid gland (7.3%). Metastatic cancer in the neck with unknown primary lesion was seen in 2.9% of the patients. Cancers associated with heavy tobacco use e.g. laryngeal cancers, lip and tongue cancers showed a very high male predilection with M:F ratios of 10.5:1, 8:1 and 6:1 respectively. 91% of the head and neck cancers were of epithelial tissue origin while sarcomas accounted for only 6.6% of the cases. The results show that head and neck cancers affect Nigerians especially males at the prime of their working life. The devastating psychosocial effects on the individual, the family and the society are enormous. Emphasis on cancer prevention is recommended.

    ABSTRACT: A one-year prospective clinical study to assess principal clinical symptoms, signs and bacteriological isolates in Nigerian children with acute otitis media. This is a multicentre study conducted from January-December, 1998 in three University Teaching Hospitals. A strict recruitment protocol was followed. Patient symptoms had to be less than one week before enrollment. Eighty-one children were recruited into the study. The major findings indicative of acute otitis media were ear pain (92.6%), fever (88.9%), redness of the tympanic membrane (89.9%) and loss of light reflex (84%). Rupture of the tympanic membrane occurred in 15 patients (18.5%) Staphylococcus aureus was the most common pathogen (50%) isolated from the ear swabs. A high index of suspicion is necessary to diagnose acute otitis media early in children especially those who may have fever as the main symptom. This will minimise the frequency of tympanic membrane perforations.
