A skin colour code for the Nigerian (Negroid) population
AO George, AO Ogunbiyi
African Journal of Health Sciences , 2006,
Abstract: Some researchers have codified various people of different racial and pigment backgrounds into skin types. The West African native population generally falls into type VI –least likely to burn. There is a need for skin colour code in a multiethnic country like Nigeria especially for the purpose of health matters. The human eye is still the most accurate instrument for the measurement of colour; its interpretation however is subjective. An objective form of documentation is needed that will be simple, quick and inexpensive. To meet the challenge for the development of a skin colour code for Nigerians, a study was conducted at the University College Hospital (UCH) Ibadan, Nigeria. The study aimed at visually identifying possible skin colours and to reproduce this on the computer. 40 colour chips were identified and found relevant for the Negroid skin in Nigeria including the Nigerian albino. The chart can be laminated using thin transparent plastic film to prevent transmission of infection from skin to skin in different people. A skin colour code can be useful for clinical evaluation of disease conditions like vitiligo as well as for epidemiological studies. Its diagnostic potential is yet to be assessed.

Challenges of dermatology training among internal medicine resident doctors in Nigeria
OE Okoro, AO Ogunbiyi, AO George, TO Bello
Jos Journal of Medicine , 2012,
Abstract: Background: The scope of dermatology training varies in teaching hospitals across Nigeria. In some institutions, there is a department of dermatology while in others it is a unit in the internal medicine department. Some medical schools have clinical postings in dermatology while others do not. Although the number of dermatologists in the country has increased compared with a few years back when they were a handful, the numbers are still inadequate to train other health practitioners on skin disorders and to meet the needs of patients. The objective of the study was to determine the perceived challenges by residents with regards to dermatology training so as to provide adequate training and ultimately increase the number of dermatologist in the country Methods: This was a cross-sectional descriptive study among resident doctors in internal medicine attending the update course of the National Postgraduate Medical College in April 2012 at Lagos using a selfadministered questionnaire. Data was analysed with SPSS 16. Result: Ninety resident doctors (58 pre-part 1 and 32 post part 1) answered the questionnaire. Seventy two (80.9%) had at least one dermatologist currently in their training institution. Sixty seven (76.1%) of the respondents (35 pre-part 1 and 32 post-part 1) had undergone postings in dermatology. The length of training varied from 1- 6 months. Sixty (66.7%) of the residents had dermatology posting as undergraduates in medical school with the length of the posting ranging from 2-6 weeks (30.0% for two weeks, 23.3% for four weeks and 41.7% for more than four weeks). Residents felt they had inadequate exposure to procedural dermatology (surgery, lasers, aesthetic), dermatopathology and management of wounds. Inadequate research opportunity (55.9%), inadequate mentors (53.2%), and inadequate facilities (53.2%) were more important challenges to dermatology training perceived by more than 50% of the residents. Conclusion: Dermatology training at both undergraduate and post graduate level in Nigeria is variable in content and duration amongst training institutions in Nigeria. There is need to standardise undergraduate and postgraduate Dermatology training. Training institution should operate a standard structured dermatology posting for undergraduate training and adhere to available curriculums provided by the postgraduate colleges for postgraduate training. Adequate facilities should be provided in the training centres and were these are not in place candidates should go to other centres with adequate training facilities for their postings.
Cutaneous features seen in primary liver cell (Hepatocellular) carcinoma patients at a University Teaching Hospital in Nigeria
AO George, JA Otegbayo, AO Ogunbiyi, SO Ola
African Journal of Health Sciences , 2007,
Abstract: Primary liver cell carcinoma (PLCC), predominantly hepatocellular carcinoma is a killer. In the southwestern region of Nigeria it occupies the second position, behind prostate cancer in males. Females account for about a third of diagnosed cases. Children are not spared. Over 80 % of PLCC cases present to the hospital at an advanced stage in Nigeria and some die within weeks of admission to the wards. A prospective hospital based study was carried out to determine muco-cutaneoeus features associated with the entity as a possible aid to diagnosis cutaneous features being considered a cheap tool that can help diagnosis in a developing country-at an affordable cost. 80 of 84 patients seen during the study period had data that were adequate for analysis. The age range was 18-76 years with a mean of 56.2 years. The male female ratio was 17:3 indicating that males remain the more affected gender. No skin feature was found to be specific to PLCC. Jaundice (63.75 %), pallor 43.75 %), peripheral oedema (32.50 %), palmoplantar macular hyperpigmentation (47.5 %/25.0% - plantar /palmar) however were the common features documented in the study. Moderate to severe pityriasis versicolor was found in 18.75 % of cases. 61.25 % had core temperature less than 36°C. Amongst non-cutaneous features found on examination, right sided upper abdominal pain/discomfort and swelling were common. While none of the features documented in this study are specific to PLCC (and most are likely related to underlying liver cirrhosis) it may be helpful to realize that Jaundice and marked palmoplantar macular pigmentation, the complaint of pain /mass, and the presence of a tender nodular mass in the right hypochondrium should make one to consider the localization of the disease to the liver. Pain/tenderness in the right hypochondrium suggest rapid growth of the liver from increased mitosis in the hepatocytes and a stretching of the liver capsule. Metastasis to the liver accounts for a very small percentage in Nigerians. A nodular liver is thus likely to be from a primary liver pathology.

Hepatitis B virus in Nigerians with Lichen planus
OOM Daramola, AO George, AO Ogunbiyi, JA Otegbayo
West African Journal of Medicine , 2004,
Abstract: Background: Lichen planus had been reported as one of the cutaneous manifestations of Hepatitis B virus (HBV) in the literature. The prevalence of HBV among Nigerians with lichen planus has not been documented in the literature despite the high prevalence of HBV in the community, and the reports of a possible relationship between lichen planus and HBV from this centre and from other regions. The aim of this study was to determine the prevalence of HBsAg amongst Nigerians with lichen planus. Method: Sixty Nigerians with lichen planus (LP group) and 30 patients with other dermatoses not reportedly associated with HBV (control group A) and 30 apparently normal subjects (control group B) were screened for the presence of HBsAg by second generation ELISA. Results: Nine (15%) of the 60 LP group, 2 (6.2%) of the 30 control group A and 2 (6.2%) of the 30 control group B were HBsAg seropositive. Conclusion: This study found a higher prevalence of HBsAg in patients with lichen planus when compared with patients with other cutaneous dermatoses and apparently normal individuals. Although a causal relationship between HBV has not been established from this study, this report reiterates the importance of screening patients with lichen planus for the presence of HBV and instituting therapy in those found positive. Key Words: Lichen planus, HBV, Prevalence, Nigerians. Résumé Introduction: Lichen planus a été portée comme l'une des manifestations cutanées de l'hépatite virale B (HBV) dans la littérature. La fréquence des cas de HBV chez les Nigerians atteints du lichen planus ne sont pas encore documentés dans la littérature en depit de la fréquence élevée de HBV dans la région et des rapports d'un rapport éventue entre le lichen planus et HBV dans ce centre et dans d'autre régions. L'objet de cette étude était de déteminer la fréquence de HbsAg parmi les Nigerians atteints du lichen planus. Méthode: On a fait passer un test de dépistage chez soixante Nigerians atteints du lichen planus (groupe de LP) et 30 patients atteints d'autre dermatites pas notees étant associées avec HBV (groupe de contr le A) et 30 sujets apparemment en bonne santé (groupe de contr le B) pour des sympt ms d'HbsAg à travers la seconde génération ELISA. Resultats:- Neuf soit 15% du groupe de 60 LP, 2 soit 6,2% du 30 groupe de contr le A et 2 soit 6,2% du groupe de contr le B étaient HbsAg séropositif. Conclusion: à travers cette étude on a noté une fréquence très élevée d'HbsAg chez des patients atteints du lichen planus par rapport avec des malades atteints d'autres dermatites cutanees et des individus apparemment en bonne santé. Quoique un rapport causal entre HBV ne soit pas encore établi à partir de cette étude, ce rapport tache de réitérer l'importance de faire le test de dépistage pour des malades atteints du lichen planus pour des sympt ms d'HBV et essaie de donner une thérapie pour ceux trouvés positifs.

AO Ogunbiyi, IO Adewole, O Ogunleye, JO Ogunbiyi, OO Ogunseinde, A. Baiyeroju-Agbeja
West African Journal of Medicine , 2003,
Abstract: A 14 year old girl was seen in the clinic with a huge vulvar wart, and warts on both tonsils. She also had poikiloderma. She had bony abnormalities, which included lobster claw abnormality of the right foot, a right cervical rib, and the right clavicle was lower than the left. There were fine parallel vertical radio-opaque lines in the distal femoral tibial metaphyses bilaterally (osteopathia striata). A diagnosis of Focal dermal hypoplasia was made. The huge vulvar wart and the warts on the tonsils were excised. She recovered promptly and she was discharged home.

African Journal of Biomedical Research , 2005,
Abstract: The effects of oral administration of extracts of raw and processed larvae of Cirina forda (Westwood) on morphometry and histo pathology were studied in albino rats. Weights of rats in the control group and in the group that were fed the processed larvae were significantly higher (p<0.05) than those of the group that received raw extract of the larvae. The relative weights of liver, heart, thyroid, pancreas and spleen were similar (p>0.05) in all the groups. The relative weight of lungs was significantly higher (p<0.05) in the control group of rats and the group that received the processed larvae than in the group given the raw larvae. Also, the relative weights of the kidneys in the rats that received the processed extract and the raw extract were similar but significantly higher (p<0.05) than the relative weight of kidney in the control group. Histopathological changes observed in the tissues of rats given the raw extract of the larvae include hepatocellular degeneration and necrosis, bile duct hyperplasia, congestion and tubular degeneration in the kidney and hyaline degeneration of myocardial fibres. The lung showed pulmonary congestion, thickened interalveolar septa, thick perivascular lymphocytic cuffs, and thickened and hyalinized tunica media of arterioles. The histopathological changes observed in the organs of the rats suggest that the raw larva of Cirina forda (Westwood) was toxic and produced a vascular circulatory disturbance resulting in organ damage in the animals. Processing the larvae by boiling and sun-drying reduced the toxicity on the liver and heart but not in the kidney. More research is needed on the toxicological aspects of the consumption of Cirina forda larva.
Prevalence of dermatological lesions in hospitalized children at the University College Hospital, Ibadan, Nigeria
OO Okafor, FO Akinbami, AE Orimadegun, CM Okafor, AO Ogunbiyi
Nigerian Journal of Clinical Practice , 2011,
Abstract: Objective: Skin disorders constitute a significant proportion of consultations in children’s clinics; however, there is a paucity of data on the prevalence of dermatological lesions in hospitalized children in Nigeria. This study determines the prevalence of dermatological lesions in hospitalized children. Materials and Methods: In this cross-sectional study, 402 children aged three months to twelve years admitted in the Pediatric wards of the University College Hospital, Ibadan, were enrolled over a six-month period. Examination of the skin and its appendages was done for each patient. Data on the socioeconomic status, hygiene, and health-related factors were also obtained using a structured questionnaire. Results: Over 96% of the children had at least one identifiable skin lesion. The five leading skin lesions were postinflammatory hyperpigmentation (49.5%), BCG scar (28.4%), Mongolian spots (27.1%), junctional melanocytic nevi (20.1%), and café-au-lait macules (18.4%). The leading infectious skin disease was pyoderma (13.4%), followed by tinea capitis (6.7%). Scarification marks (P=0.001), tinea capitis (P=0.014), plantar fissuring (P=0.001), and impetigo (P=0.016) were associated with low socioeconomic classes, while the presence of BCG scar (50.0%) was associated with the high socioeconomic class. Conclusions: This study shows that dermatologic lesions are common in hospitalized children. Identifying them will provide an opportunity for pediatricians to educate parents on the various causes as well as prevention of lesions.

The Challenges of Language Teaching in the 21st Century
Oluranti Ogunbiyi
Pakistan Journal of Social Sciences , 2012,
Abstract: This study takes a look at some of the challenges of language teaching in our educational institutions. It highlights the place of language in the National Policy on Education and discusses the different categories of language taught in our schools. The study concludes that no education can take place effectively without the use of language; therefore, the language factor in educational system cannot be overemphasized. Despite the exciting possibilities the Internet offers for language teaching and the popularity of learner-focused approach, the teacher still remains an important figure in language teaching. Education is best given in the language of the people and to neglect the peoples language is to neglect the very essence of their existence.
