Genital Chlamydia trachomatis infection causes significant morbidity and mortality in women. A number of epidemiologic studies have suggested that Polymerase Chain Reaction (PCR) is more accurate as a diagnostic tool for Chlamydia trachomatis.However, the use of serological markers may be cost effective and practical in diagnosing and estimating the burden of the disease in resource limited countries.This study was aimed at determining the serological markers (IgG, IgM and IgA) of Chlamydia trachomatis, evaluate the association between Chlamydia trachomatis infection and the sociodemographic characteristics and clinical diagnosis of the participants. This was a cross sectional hospital-based study in which blood samples from 145 consenting participants were tested for IgG, IgM and IgA antibodies against Chlamydia trachomatis using enzyme linked immunosorbent assay and their clinical diagnosis, retrieved from their case notes. The cumulative prevalence of seropositivity for Chlamydia trachomatis (IgG, IgM, IgA) was 112 (77.2%) while 33 (22.8%) were seronegative. The overall predominant seromarker was IgG 91(62.8%) while IgM and IgA accounted for 85(58.6%) and 54(37.2%) respectively. A statistically significant association was found between Chlamydia trachomatis infection and PID (p value = 0.031), primary infertility (p value 0.011) and level of income (p value= (0,045).

(The Brazilian Society of Anatomy (SBA), 2017) Salami, A.; Ajani, M.; Orhorho, I.; Ogun, G.; Adeoye, A.; Okolo, C.; Oluwasola, A.; Ogunbiyi, J.
Introduction: The average brain weight of adult humans, using Caucasian figures, is said to be between 1300g to 1400g. Few studies have however been done to make actual evaluations of brain weights in adult Africans. This study seeks to examine the weight of brains from people of African descent with respect to variations in sex and age in decades using autopsy specimens. Materials and Methods: Analysis of the weight of brains removed from both male and female adult patients during fresh autopsy of their bodies in our center over a ten year period was done. The study criteria required non-involvement of the central nervous system in the cause of death. The brains were grouped based on age in decades and further grouped into early, middle and late age groups. Descriptive statistical analysis was done using SPSS 20 statistics software. Results: A total of one hundred and sixteen brains were included in the study and the mean brain weight was 1280g with a range between 1015g to 1590g. There was no statistically significant difference in the mean brain weight of the different age groups. The average male brain was heavier than those of females and the difference was statistically significant. Conclusion: The brain weight of adult Africans in our study is similar to that seen in Caucasians. There is no statistically significant difference in the brain weight of adults from early adulthood to the elderly adults. Male adults have statistically heavier brains than the females
Clinicopathological pattern of oestrogen receptor, progesterone receptor and human epidermal growth factor receptor-2 over-expression of epithelial ovarian carcinomas in Nigeria
(Makerere University, Medical School, 2023) Ajani, M. A.; Lawan, A.; Oke, T.; Khramtsova, G.; Nwanji, I.; Salami, A.; Awolude, O.; Ebili, H.; Onwukamuche, M. E.; Sveen, E.; Yoshimatsu, T.; Olopade, O. I.
Background: Ovarian cancer is the leading cause of death from all gynaecological malignancies. Only few biomarkers of epi thelial ovarian cancer (EOC) prognosis have been studied so far among Nigerian patients. Objective: To determine the pattern of oestrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER-2) expression in patients with EOC seen in Nigeria Materials and Methods: This was a retrospective multicentre study of 102 cases of epithelial ovarian cancers. Relevant clinical information was obtained from hospital-based records in the 3 participating centres. Tissue microarrays were constructed using representative tumour tissue and the ER, PR and HER2 immunohistochemical staining was carried out at the University of Chicago, United States of America. Results: Serous carcinomas predominated (71% of cases). ER positivity was observed in 31.4%, PR positivity in 21.5% and HER2/neu in 16.7% of tumours. Fifty-two percent of tumours were triple negative. Serous tumours were significantly asso ciated with ER positivity (p=0.001). Mean patient age for EOC was 52.6 ± 13.1 years. There were no statistically significant associations between hormone receptor status and histological grade, FIGO staging or survival. Conclusion: Serous tumours were significantly associated with ER expression while non-serous tumours tended to be triple negative.
Correlation of intraoperative cytological and final histological diagnoses
(Wiley, 2014) Salami, A.; Adeleye, A.; Ogun, G.; Adeoye, A.; Adeolu, A.; Okolo, C.; Eze, U.; Abdullahi, Y.; Lawan, A.; Ogunbiyi, J.; Akang, E.; Shokunbi, M.; Azeez, A.; Malomo, A.
Objective: Intraoperative cytology is a cost-effective, rapid, and easy technique, and studies have shown good correlation between intraoperative cytology and histology. We undertook this study to compare the intraoperative cytology diagnoses of brain lesions made in our unit over a 10-year period with the definitive histological diagnoses. The aim was to determine the degree of accuracy of this procedure. Study design: This is a retrospective study of intraoperative neuropathology consultation cytology smears or imprints and histology of 69 cases obtained over a 10-year period. Cytology smears were stained using both Papanicolaou and Giemsa. Histology sections were prepared from routine formalin-fixed paraffin- embedded tissue and stained using H and E method. Each of the smears and histology samples were assessed by at least two pathologists. Cytological diagnosis was correlated with final histological diagnosis. The sensitivity and specificity of cytological diagnosis was evaluated using final histological diagnosis as gold standard. Results: Correlation was strongest with inflammatory lesions followed by low-grade neoplasms. High-grade neoplasms also showed good concordance, but the degree of correlation was lower than in the other categories. Misdiagnosis was commonest with benign tumors. Conclusion: Intraoperative cytology is a relatively simple, reliable, and accurate diagnostic technique and should be more commonly used, particularly in low-resource settings. Diagn. Cytopathol.

(College of Medicine, University of Ibadan, 2015) Oluwasola, A. O.; Adeoye, A. O.; Afolabi, A. O.; Adeniji-Sofoluwe, A. T.; Salami, A.; Ajani M. A.; Ogundiran, T. O.; Obajimi M. O.
Tru-cut needle biopsies form an integral part of Triple assessment of breast cancer and include clinical assessment, mammography and core needle biopsy. No study has been done to evaluate the validity o f the procedure in our environment. This study was done to evaluate the validity of core needle biopsies in our centre. Method'. A retrospective study of patients with tru-, cut needle biopsies of breast lumps and follow-up excisional biopsy or m astectomy done in the Department of Surgery, University College Hospital, Ibadan over a ten year period was done. Fifty one patients who fulfilled the inclusion criteria had their records obtained from the Department of Pathology. The diagnosis was classified into benign and malignant with the excisional biopsy or mastectomy diagnosis used as the gold standard. The sensitivity, specificity and accuracy were calculated and kappa was also done to evaluate the degree of agreement. Results'. A total of 51 cases were included in this study. The average age o f the patients was 47±13years with a range from 19 to 81 years. Thirty of the biopsies (59%) had a definitive diagnosis of malignancy while twenty one (41%) were benign. The overall sensitivity, specificity and accuracy were 86%, 71% and 80.4% respectively. The specificity of malignant biopsies was 68% while benign was 35%. The level of agreement for malignant biopsies was higher than benign biopsies with a kappa of 0.39 for malignant diagnosis as against 0.29 for benign. C onclusion: T ru-cut needle biopsies have a comparable sensitivity and specificity to excisional biopsies. Diagnostic accuracy can be further enhanced with the adoption of image guided biopsies.

(African Journals OnLine, 2019) Ajani, M. A.; Salami, A.; Nwanji, I. D.; Olusanya, A. A.; Fatunla, O. E.
Background: Endometriosis poses a significant burden mainly to women of child bearing age. Historically, endometriosis was thought to be of low prevalence among African women. However, recent studies have documented an increased prevalence than previously thought. This study aimed to determine the distribution and characteristics of endometriotic lesions among Nigerian women. Methods: A retrospective study of all histologically diagnosed cases of endometriosis from the records of the Department of Pathology, University College Hospital, Ibadan from 1st January, 1997 to 31st October, 2018.The age of the women, location and distribution of the lesions were analysed. Results: A total of 85 cases of endometriosis were diagnosed histologically in the period under review. The mean age was 35 years with an age range of 18 to 52 years. The most commonly affected age groups were those between 30-39 years (47.1%) and 20-29 years (30.6%). The most commonly affected site was the ovary (58.8%) followed by the umbilicus (11.9%) and fallopian tubes (9.4%). Fourteen patients (28%) had bilateral ovarian involvement. Left sided ovarian lesions predominated (61.1% versus 38.9%). Eighteen (21.2%) patients had lesions at more than one site frequently involving both ovaries. Conclusion: Endometriosis affected mainly women of childbearing age with particular predilection for the ovaries. Endometriosis affecting the umbilicus is not uncommon among Nigerian women.

The expression status of human epidermal growth factor receptor 2 in epithelial ovarian cancer in Ibadan, Nigeria
(2016) Ajani, M. A.; Salami, A.; Awolude, O. A.; Oluwasola, A. O.; Akang, E. E. U.
Background: It has been proposed that the overexpression of the human epidermal growth factor receptor 2 (HER2/neu protooncogene) could be a possible therapeutic target in epithelial ovarian cancer, as has been the case in breast carcinomas. However, there is lack of knowledge on the status of the gene in neoplasms which occur in black women. The objective of this study was to determine HER2/neu expression status in EOC in black women. Method: Ninety cases of EOC were evaluated for HER2/neu protein expression using immunohistochemistry. Results: HER-2/neu expression was observed in 33 of the 90 cases (37%), of which 15 EOC cases (17%) were weakly or moderately positive, and 18 (20%) strongly positive. A significant association was not found between HER-2/neu expression and age, International Federation of Gynecologists and Obstetrics (FIGO) stage, grading and histological subtypes (p-values of 0.463, 0.360, 0.975 and 0.168, respectively). However, there were more cases of advanced-stage disease (III/IV) with HER-2 expression than early-stage EOC (I/II). In this study, 21%, 36% and 42% of HER2/neu-positive tumours were grades 1, 2 and 3, respectively. A higher proportion of serous carcinomas (as opposed to mucinous carcinomas) was also observed to be ER2/neu positive. Conclusion: HER2/neu expression was observed to increase with advanced stages of cancer, and was more commonly seen in serous, rather than in mucinous, carcinomas.
Gender differential in inclination to donate brain for research among Nigerians: the IBADAN Brain Bank Project
(Springer Nature, 2019) Akinyemi, R.; Ojagbemi, A.; Akinyemi, J.; Salami, A.; Olopade, F.; Farombi, T.; Nweke, M.; Uvere, E.; Aridegbe, M.; Balogun, J.; Ogbole, G.; Jegede, A.; Kalaria, R.; Ogunniyi, A.; Owolabi, M.; Arulogun, O.
Background: Laboratory-based studies of neurological disease patterns and mechanisms are sparse in sub-Saharan Africa. However, availability of human brain tissue resource depends on willingness towards brain donation. This study evaluated the level of willingness among outpatient clinic attendees in a Nigerian teaching hospital. Methods: Under the auspices of the IBADAN Brain Bank Project, a 43—itemsemi-structured interviewer—administered questionnaire was designed to evaluate knowledge, attitude, and beliefs of individuals attending Neurology, Psychiatry and Geriatrics Outpatient clinics regarding willingness to donate brain for research. Association between participants characteristics and willingness towards brain donation was investigated using logistic regression models. Analysis was conducted using Stata SE version 12.0. Results: A total of 412 participants were interviewed. Their mean age was 46.3 (16.1) years. 229 (55.6%) were females and 92.5% had at least 6 years of formal education. Overall, 109 (26.7%) were willing to donate brains for research. In analyses adjusting for educational status, religion, ethnicity, marital status and family setting, male sex showed independent association with willingness towards brain donation OR (95% CI) 1.7 (1.08–2.69), p = 0.023. Participants suggested public engagement and education through mass media (including social media) and involvement of religious and community leaders as important interventions to improve awareness and willingness towards brain donation. Conclusion: The survey revealed low willingness among outpatient clinic attendees to donate brain for research, although men were more inclined to donate. It is imperative to institute public engagement and educational interventions in order to improve consent for brain donation for research.
Histopathologic pattern of posterior cranial Fossa tumours in a West African tertiary
(Zambia Medical Association, 2019) Salami, A.; Adeleye, A.; Oyemolade, T.; Ajani, M.; Usiholo, A.; Nweke, M.; Adeolu, A
Introduction: The posterior cranial fossa contains many vital structures and mortality of patients with tumours occurring in this area is high. Studies done in other geographic locations showed a higher occurrence of posterior cranial fossa tumours in paediatric patients while benign tumours were more commonly seen. Epidemiological data of tumours in this area in our environment is scarce. This study was done to ascertain the histopathologic pattern of tumours in the posterior cranial fossa in a predominantly black population. Method: A ten-year retrospective study of histologically diagnosed posterior cranial fossa tumours seen in our hospital facility was done. A total of 72 cases in which neurosurgical intervention was carried out were identified and this included all age groups. The age, sex, site of tumour and histological diagnosis were extracted from the patients' records. Result: Adult patients predominated with 55.6% while the paediatric patients were 44.4%. The male to female ratio in the paediatric patients was 2.56:1 but the ratio was equal in the adult patients. WHO grade 1 tumours were the commonest tumours seen (45.8%) while grade II tumours were the least (4.2%). Medulloblastomas (20.83%), Pilocytic astrocytomas (18.6%) and Meningiomas (8.33%) were the commonest tumours seen. Commonest locations are in the cerebellar hemispheres (56.9%) and the fourth ventricle (13.89%). Conclusion: Our study showed a higher occurrence of Medulloblastomas in contrast to other studies which have shown more of Schwannomas, a tumour type that was rare in this study. The relatively low number of metastatic tumours in this study may be due to lack of presentation of such patients.

(Association of Resident Doctors of Jos University Teaching HospitalAssociation of Resident Doctors of Jos University Teaching Hospital, 2016) Ajani, M. A.; Aramide, K. O.; Salami, A.; Okolo, C. A.
Background: Ovarian tumours are common form s o f neoplasms in women. This study aims to determine the histopathological pattern o f primary ovarian neoplasms in South-western Nigeria. Method: A retrospective study was undertaken to review the histopathology reports o f all primary ovarian neoplasm specimens submitted to the Department o f Pathology, University College Hospital, Ibadan from January 1991 to June 2013. Patients'biodata were extractedfrom the requestforms and surgical day books. Results: There were 821 cases o f primary ovarian neoplasms. 359 (43.7%) cases were surface epithelial neoplasms which were found in patients with age range 10-89 years. Three hundred and thirteen (38%) cases o f germ cell tumour were found in patients with age range 0-70 years. One hundred andforty-six (17.8%) cases ofsex cord stromal tumour werefound in patients with age range 0-99 years. Mature Cystic Teratoma was the most common (54.7%) among benign ovarian neoplasms with 20-29 years being the age range with highest tumours while serous cystadenocarcinoma was the most common (33.2%) primary malignant ovarian neoplasms with 50-59years being the age range with highest tumours. Conclusion: Surface epithelial tumours were the most common ovarian neoplasmfollowed by germ cell tumours. This pattern is observed in most parts of Nigeria, some African and Asian countries, and in the Western world.
Hormone–receptor expression status of epithelial ovarian cancer in Ibadan, South-Western Nigeria
(African Field Epidemiology Network, 2017) Ajani, M. A.; Salami, A.; Awolude, O. A.; Oluwasola, A. O.
Epidemiological evidence strongly suggests that steroid hormones are implicated in the pathogenesis of ovarian cancer. Estrogen receptor (ER) and Progesterone receptor (PR) are prognostic indicators for a number of epithelial tumors and may play the same role in ovarian cancers. This study aims to evaluate the expression of ER and PR in epithelial ovarian cancer (EOC) in an African population and compare it with other prognostic factors such as age, International Federation of Gynaecology and Obstetrics (FIGO) stage, grade and histological subtype. Methods: Ninety cases of histologically confirmed EOC were reviewed. Immunohistochemistry was used to assess their ER and PR expression status and was then compared with other demographic variables using statistical methods, with level of significance set at p < 0.05. Results: 30.2% and 8.3% of serous and mucinous carcinomas respectively were ER positive while 41.2% and 22.5% of both tumour types were PR positive. One of the two endometrioid carcinomas showed PR expression but neither were positive for ER. The only case of Brenner tumour in the series was ER positive but negative for PR. There was a significant association between ER and the histological subtypes (p = 0.042) while no significant association was found between PR expression and histological subtypes (p = 0.650). No significant association was found between hormone receptor status, age and stage of the EOC. Conclusion: The study showed a lower ER expression in serous carcinoma compared to large cohorts from developed countries. Future translational studies could be used to determine response of EOC to endocrine therapy.

Ameloblastoma is an uncommon and locally aggressive, benign, odontogenic tumor, with local recurrence when not adequately excised. A rare variant of this neoplasm with the benign features but accompanied with metastases has been described. This rare variant is malignant ameloblastoma and is known to have a poor prognosis. We present the case of a young woman who had recurrent mandibular tumors, which were resected twice and histologically reported as ameloblastoma. Four years later, she presented with pulmonary metastasis and atelectasis. A review of the literature on this very rare neoplasm was also performed.

Proliferaton index in pituitary adenomas from a black African population
(Elsevier B.V., 2016) Salami, A.; Ajani, M.; Adeolu, A.; Ogun, O.; Adeleye, A.; Ogun, O.; Okolo, C.; Malomo, A.; Akang, E.
Background: The WHO has recognized a variant of pituitary adenomas with potential aggressive behavior which have been termed atypical pituitary adenomas. This group of tumours are recognized by their mitotic rate of more than >3%, p53 expression and invasion of surrounding structures. There has however been no study of the occurrence of these tumours in a black African population. This study is a preliminary attempt to examine this group of tumours in blacks. Methods: This study retrospectively reviewed fifty-seven histologically diagnosed and immunohistochemically characterized pituitary adenomas received in our department over a twenty-one year period. Specimens were stained with ki67, a nuclear marker of cell proliferation which has been identified as the single best predictor of atypical pituitary adenoma. Results: Twelve of the tumours showed atypical features with eight (67%) of these tumours being prolactinomas. Two of the tumours were gonadotrophs and two were null cell adenomas. There was no correlation with age or gender. Two of the tumours required neurosurgical re-exploration with one of these showing a higher mitotic index in the second biopsy. Conclusion: The study suggests similarity in the rate of occurrence of pituitary adenomas with atypical features in a black African population with what is seen in Caucasians. Prolactinomas constitute a significant percentage of the tumours with this feature
Secondary ovarian neoplasms in a tertiary hospital in South-Western Nigeria
(Association of Resident Doctors, University College Hospital, Ibadan, Nigeria, 2019) Ajani, M. A.; Iyapo, O.; Salami, A.; Okolo, C. A.
Background: The ovary is a common site of involvement for metastases constituting 5-30% of all malignant ovarian neoplasms. Over half of these tumours are bilateral. The commonest sources are stomach, large bowel, appendix, breast, uterus (corpus and cervix) and lung. Aim: The aim of this study was to determine the histopathological pattern of metastases to the ovary at the University College Hospital, Ibadan, South western Nigeria. Material and Methods: This was a retrospective study. All histologically confirmed cases of metastases to the ovary from the records and files of the Department of Pathology, University College Hospital (UCH), Ibadan between January 1991 and June 2013 were used for the study. These were cases diagnosed following total abdominal hysterectomy, total abdominal hystero-salpingo oophorectomy, bilateral salpingo-oophorectomy, omentectomy, and multiple peritoneal biopsies and post-mortems at the University College Hospital between January 1991 and June 2013. Cases with inadequate clinical data and whose blocks and or slides could not be retrieved were excluded from the study. The data obtained were analysed using the Statistical Package for Social Sciences version 20 Results: There were 46 cases of metastases to the ovary constituting 5.3% of total ovarian neoplasms. Thirty (63.9%) cases were metastatic carcinomas with the affected patients’ age range of 20-79 years, and peak incidence within the age group of 30-39 years. Nineteen out of 30 cases of metastatic carcinomas were from adenocarcinoma of colon, 6 cases were from the gastric carcinoma while the remaining five cases were from the squamous cell carcinoma of the uterine cervix. Fifteen (31.9%) cases of Burkitt Lymphoma were found with patients with age range of 0-39 years, and the peak age of occurrence at the 2nd decade. The only case of metastatic Malignant Mixed Mullerian Tumour and metastatic Leiomyosarcoma were found in the 3rd and 4th decades of life respectively Conclusion: This study has shown that metastases to the ovary occur in younger age groups in our environment. Therefore this study emphasizes that in young females with ovarian masses, the likelihood of metastatic tumours should not be discarded because, correct and precise diagnosis of secondary ovarian malignancy is critical as it has significant implication on the patients’ choice of management and prognosis.
