Background. Women with African ancestry in the United States and in continental Africa have been found to have exception- ally increased frequencies of triple-negative breast cancer (TNBC), prompting speculation that this risk may have an inherited basis and may at least partially explain breast cancer outcome disparities related to racial/ethnic identity. Our goal was to evaluate the breast cancers diagnosed in one of the largest health care facilities in western Africa, and to compare the frequencies as well as risk factors for TNBC versus non-TNBC. Methods. We reviewed all breast cancer cases that had immunohistochemistry (Novolink Detection system), in 2010. Results. The overall study population of 223 breast cancer cases was relatively young (median age 52.4 y), and most had palpable tumors larger than five centimeters in diameter. More than half were TNBC (130 cases, 58.3%). We observed similar frequencies of young age at diagnosis, stage at diagnosis, and tumor grade among cases of TNBC compared to cases of non-TNBC. Conclusion. Ghanaian breast cancer patients tend to have an advanced stage distribution and relatively young age at diagnosis. The triple-negative molecular marker pattern is the most common seen among these women, regardless of age, tumor grade, and stage of diagnosis. Additional research is necessary regarding the causes of TNBC, so that we can elucidate the reasons for its increased prevalence among women with African ancestry.

Goitre in the West African sub-region is caused by iodine deficiency and goitrogens in the diet. Supplementary iodine nutrition on a mass scale was started in Ghana in 1996. In areas where iodine deficiency have been corrected the histological pattern of goitre changes and this influences surgical decision making. Data on the histological types of goitre in our institution is lacking.Objective: To define the histopathological types of goitre in this initial period of iodine supplementation and relate this to the types of thyroid surgeries that were performed.Methods: It was a prospective study of consecutive patients who underwent thyroidectomy from January 2003-December 2007. Descriptive statistics was employed in analyzing the dataResults: Five hundred and twenty eight cases were studied made up of 470 (89%) females and 58 (11%) males with mean age of 41.98yrs, SD ±12.90yrs. The excised mean thyroid tissue weight was 161.4g, SD ±116.3yrs. Hyperplastic goitres were 373 (70.7%), toxic goitre 70 (13.3%), adenoma 37 (7.0%), carcinoma 25 (4.7%) and thyroiditis 23 (4.4%). Papillary carcinoma accounted for 56% (14) cancers. Subtotal thyroidectomy was performed in 278 (52.7%) of patients, near total thyroidectomy 107 (20.3%), lobectomy 98 (18.6%), total thyroidectomy 24 (4.5%), excision or completion thyroidectomy 20 (3.8%) and de-bulking 1 patient. Overall, complications occurred in 32 patients (6.1%) and were made up mostly of haemorrhage in 10 (1.9%), Hypocalcaemia 10 (1.9%), unilateralRecurrent Laryngeal Nerve(RLN) injury 3 (0.57%), Tracheal collapse 3 (.57%) and Bilateral RLN injury 2 (0.4%).Conclusion: The introduction of iodine supplementationon a mass scale in Ghana is yet to have its fullest impact on thyroid diseases. Goitres are still large and cause pressure effects. Toxic, inflammatory and malignant goitres are gaining prominence, and surgery for malignant goitre was oncologically inadequate.Near total thyroidectomy is recommended as the minimum surgery to avert the need for completion thyroidectomies in view of the lack of preoperative pathological diagnosis of thyroid lesions. Key words: Goitre, iodine deficiency, iodated salt, Endemic goitre, Thyroidectomy.

Cervical cancer is a major cause of cancer related mortality in the developing countries, although preventable. The aim of this study was to use a retrospective descriptive study to determine the prevalence and the clinico-pathological characteristics of cervical cancer among genital tract ma-lignancies. This study reviewed all histologically confirmed female genital tract malignancies for cervical cancers from January 2002 to December 2011. The clinico-pathological features of women with cervical cancer were analyzed using SPSS software (version 18). A total of 1011(70.8%) out of 1,427 female genital tract malignancies were cervical cancers. The average prevalence of cervical cancer was 71.0%. The mean age of women with cervical cancer was 57.8(SD=13.8) years. The youngest patient was 22 years. The commonest (76.9%) presentation was bleeding per vaginalm followed by fungating cervical masses (12.4%). Majority (88.9%) of the bleeding were unprovoked and in postmenopausal women (98.8%). The major types of cervical cancers were Squamous cell carcinoma (SCC) (90.1%) and adenocarcinoma (5.8%), both were common in the elderly. The com-mon histological subtypes of cervical cancers in the study were; keratinizing SCC (73.3%), non-keratinizing SCC (14.7%), endometroid adenocarcinoma (4.5%), adenosquamous carcinoma (2.6%) and basaloid SCC (1.4%). This study found high prevalence of cervical cancer among female geni-tal tract cancers in Accra Ghana. The women were relatively older and presented with advanced stage of the disease. SCC was the major histological type of cervical cancer.Keywords: Ghana, cervical cancer, postmenopausal, women, premalignant, genital tract

Malignant Tumours of the Female Genital Tract: A 10-Year Histopathological Review at the Korle-Bu Teaching Hospital (2002-2011) Abstract Background: Morbidity data on female genital tract malignancies are limited in Ghana. The aim of this study was to establish the anatomical distribution and the histopathological features of female genital tract malignancies (FGTMs) in a tertiary hospital in Ghana. Material and methods: A comprehensive review of the all histologically confirmed FGTMs from January 2002 to December 2011 was conducted to assess their clinicopathological features. Results: There were 1,536 cases of FGTMs. The anatomic distributions were: uterine cervix 1086 (70.7%), corpus uteri 356 (23.2%), vagina 58 (3.8%) and vulva 36 (2.3%). The mean ages of women diagnosed with these cancers were: corpus uteri (59.5 years; SD = 14.2), uterine cervix (57.7 years; SD = 13.8), vulva (56.3 years; SD = 13.4) and vagina (52.5 years; SD = 18.1). The proportions of postmenopausal women were: corpus uteri (76.8%), uterine cervix (65%), vulva (55.6%) and vagina (50.0%). Women with corpus uteri and uterine cervix malignancies presented commonly with bleeding per vaginam while those with vulva and vagina malignancies presented mostly with ulcers and masses. The common histological subtypes were; cervix: Squamous cell carcinoma (SCC) (69.2%), adenocarcinoma (18.1%) and MMMT (3.8%) (2.3%); Corpus uteri: adenocarcinoma (61.8%), malignant mixed mullerian tumours (MMMT) (15.4%) and choriocarcinoma (8.4%); Vagina: SCC (62.1%), adenocarcinoma (22.4%) and MMMT (5.2%); Vulva were: SCC (69.4%), adenosquamous (8.25) and stroma (5.6%). Conclusion: The study found that FGTMs were commoner in relatively older women (mean age 57.9 years), majority being postmenopausal (66.4%). The predominant type of FGTM was cancer of the uterine cervix with bleeding per vaginam as the common clinical presentation.

- Abstract
There is a scarcity of data on thyroid disorders in Ghana. This retrospective study examined the spectrum and incidence of thyroid disorders by reviewing all thyroid disorders reported in the De-partment of Pathology, Korle-Bu Teaching Hospital (KBTH) between 2004 and 2010. Data was collected on the clinical and histological characteristics of all thyroid disorders reported during the study. 1300 (3.7%) cases were reported, representing an annual incidence of 185.7 cases. The ages ranged from 1-86 years with a mean of 41.5 (SD=13.9). Most [353 (27.4%)] of the cases were be-tween 30-39 years group. Majority, 1141(87.8%) were females. The top eight common thyroid dis-eases were; non-toxic multinodular goitre 1002(77.5%), follicular adenoma 86(6.6%), diffuse toxic goitre 42 (3.2%), papillary thyroid carcinoma 40(3.1%), thyroglossal duct cyst 35(2.7%), Hashimo-to’s thyroiditis 28(2.2%), lymphocytic thyroiditis 22(1.7%) and follicular carcinoma 17(1.3%). Sixty-six (43.4%) of the neoplastic thyroid disorders were malignant with a prevalence of 0.18 among thy-roid samples and annual incidence of 9.40 cases. The commonest thyroid cancer was papillary car-cinoma 40(60.6 %), with a mean age of 38.3 SD=16.1 years, majority, 34 (82.9%), were women. A wide spectrum of thyroid disorders exists in Ghana, with an annual incidence of 185.7 cases. The commonest malignant thyroid disorder was papillary carcinoma, though iodine deficiency is en-demic in Ghana and on this basis; one would have expected follicular carcinoma to be the com-monest thyroid cancer in Ghana.

This study utilized retrospective autopsy data to examine the relationship between HIV co-infection and mortality pattern of purulent meningitis. All autopsy log books and available hospital files were reviewed for information on purulent meningitis for which autopsies were performed in 2005 through 2009 at the Pathology Department of the Korle-Bu Teaching Hospital, Accra, Ghana. The mean ± SD of the studied population was 34.6±19.5 years and the prevalence of HIV co-infection among this population was 4.3%. Female participants died at a significantly younger age (31.9±19.7 years; p=0.0103) compared to their male counterparts (36.1±19.2 years). Most of the cases in HIV negative purulent meningitis death had purulent meningitis as the primary cause (i.e. 87.9% vs 18.5%) whereas most of the death in HIV co-infection cases had purulent meningitis as the secondary cause of death to other conditions such as CVA, pneumonia, head injury due to road traffic accidents and various malignancies (i.e. 81.5% vs 12.1%). Purulent meningitis secondary to other conditions is more likely to be the cause of death in aged subject. The prevalence of purulent meningitis with HIV co infection was low in this study. The mortality pattern is related to the age and gender of the studied population and whether the purulent meningitis is primary or as a co infection with HIV.

- Abstract
The levels of Lower Limit of Detection (LLD) and the Biological Detection Limit (BDL) for prostate-specific antigen (PSA) by an assay system are essential for successful prediction of recurrent disease after radical prostatectomy. A study was conducted to evaluate an Immunoradiometric Assay (IRMA) system to establish the LLD and BDL for PSA. The IRMA was validated by Recovery and Dilution experiments, where standard quantities of purified free-PSA (f-PSA) and PSA complexed to α1-antichymotrypsin (PSA-ACT) were added to sera from healthy subjects and patients harbouring prostate cancer. The dilution and recovery experiments revealed an over-recovery for f-PSA (112.4 ± 12.4 %) and an under-recovery for PSA-ACT (86.4 ± 13.6 %). Six pools of zero standard and sera from 6 radical prostatectomy patients (with no histopathological evidence of relapse) were analysed in 20 replicates by the IRMA system, and the LLD and BDL values determined were 0.11 ng mL-1 and 0.34 ng mL-1 (within the standard ranges of 0.03 - 0.11 ng mL-1 and 0.06 - 0.83 ng mL-1 respectively). The results indicated satisfactory evaluation, and the data generated with the IRMA protocol was reliable.

Case Report - Abstract
SummaryWe report a case of perinatal death from hypoglycaemia in an infant of a mother who had fasting hyperglycaemia diagnosed at 31 weeks of gestation and managed with diet alone. Blood glucose values were not conclusive of gestational impaired glucose tolerance by WHO and American Diabetes Association standards, yet autopsy histological findings in the pancreas were similar to that described in neonates of a diabetic mother. We therefore emphasize that all pregnant women with inconclusive glucose values for diagnosis of full blown gestational diabetes mellitus should be fully investigated and closely monitored during antenatal care. The infants of such mothers may be at a higher risk of hypoglycemia in the immediate post natal period and would require similar monitoring and aggressive management.

- Abstract
Background and Aims: Liver fibrosis leading to chronic liver disease (CLD) is a major cause of morbidity, mortality and health-care expenditure worldwide. The "gold standard" for diagnosis and staging of liver fibrosis is histological analysis of liver tissue obtained by liver biopsy, an invasive procedure. Therefore, there is the need to identify noninvasive and inexpensive markers for diagnosis and staging of liver fibrosis. This study aimed at evaluating the correlation of hyaluronic acid (HA) and 25-hydroxyvitamin D (25-OH vitamin D) serum levels as markers of fibrosis with histologically staged and graded liver biopsies obtained from CLD patients., Methods: This was a case-control study involving 40 CLD patients requiring liver biopsies and 40 controls. Liver biopsies were staged to determine the degree of fibrosis. Serum levels of 25-OH vitamin D and HA were determined using ELISA. Statistical analyses were performed to determine differences in HA and 25-OH vitamin D levels between controls and patients as well as to correlate the biomarkers with the stages of fibrosis., Results: CLD patients showed significant ( p < 0.001) increase in the levels of AST, ALT, GGT, compared to the controls. Patients also had significantly ( p < 0.001) lower serum 25-OH vitamin D and higher HA ( p < 0.001) levels compared to the controls. Additionally, 25-OH vitamin D levels of the CLD patients were significantly different across the stages of liver fibrosis likewise serum HA levels. Furthermore, 25-OH vitamin D levels inversely correlated with the severity of liver fibrosis. A significant negative correlation ( r = -0.33, p < 0.05) between CLD patients' HA and 25-OH vitamin D were found., Conclusion: CLD patients had significantly reduced serum 25-OH vitamin D and higher HA. Both markers correlated with the degree of liver fibrosis. These findings have major clinical translatable implication in the use of vitamin D supplementation in the management of CLD in Ghana., Competing Interests: Justice Moses K.

- Abstract
Objective: To compare neurological functioning of neonates born to mothers with and without malaria in pregnancy., Methods: Pregnant women presenting at Korle Bu Teaching Hospital, Ghana were recruited into this prospective observational study. Malaria exposure was determined by clinically documented antenatal malaria infection; parasitemia in maternal, placental, or umbilical cord blood; or placental histology. Neurological functioning was assessed using the Hammersmith Neonatal Neurological Examination within 48 hours of birth. Performance was classified as "optimal" or "suboptimal" by subdomain and overall., Results: Between November 21, 2018 and February 10, 2019, a total of 211 term-born neonates, of whom 27 (13%) were exposed to malaria in pregnancy, were included. In the reflexes subdomain, exposed neonates tended to score lower (adjusted mean difference -0.34, 95% confidence interval -0.70 to 0.03), with an increased risk (adjusted risk ratio 1.63, 95% confidence interval 1.09 to 2.44) of suboptimal performance compared with unexposed neonates. There were no significant between-group differences in scores or optimality classification for the remaining subdomains and overall., Conclusions: Malaria-exposed neonates had similar neurological functioning relative to unexposed neonates, with differences confined to the reflexes subdomain, suggesting potential underlying neurological immaturity or injury. Further studies are needed to confirm these findings and determine the significance of malaria in pregnancy on long-term neurological outcomes., (Copyright © 2021 The Authors.

- Abstract
Background: Breast cancer is the commonest malignancy in women worldwide. It is estimated to affect approximately 1.5 million women annually and responsible for the greatest number of cancer-related mortalities among women. In 2018, breast cancer mortalities stood at 627,000 women representing approximately 15% of all cancer deaths among women. In Ghana, breast cancer is the second leading cause of cancer deaths, with an incidence of 2,900 cases annually; one of eight women with the disease die. This gives impetus to the fight for improved early detection, treatment, and/management. In this light, we investigated the potential of death-associated protein kinase 1 (DAPK1) as a biomarker for breast cancer. As a tumour suppressor, its expression is activated by several carcinogens to influence cellular pathways that result in apoptosis, autophagy, immune response, and proliferation., Aim: To investigate DAPK1 as a blood biomarker for breast cancer., Methods: Blood samples of participants diagnosed with breast cancer and healthy controls were collected and processed to obtain serum. Information on age, treatment, diagnosis, and pathology numbers was retrieved from folders. Pathology numbers were used to retrieve breast tissue blocks of patients at the Department of Pathology of the KBTH. Tissue blocks were sectioned and immunohistochemically stained with anti-DAPK1 and counterstained with hematoxylin to determine the DAPK1 expression levels. DAKP1 levels in blood sera were quantified using a commercial anti-DAPK1 ELISA kit. Case and control group means were compared using one-way ANOVA and Chi-square test. Statistical significance was set at p ≤ 0.05. Results and Discussion . DAPK1 levels were higher in sera and breast tissues of breast cancer patients than controls. The augmented DAPK1 expression can be interpreted as a stress response survival mechanism to remediate ongoing deleterious events in the cells orchestrated by carcinogenesis. In the presence of abundant DAPK1, the proliferative power of cells (both cancerous and noncancerous) is increased. This may explain why high DAPK1 expression strongly associates with aggressive breast cancer phenotypes like the ER-negative breast cancers, especially the triple-negative breast cancers (TNBC) which are the most aggressive, fast-growing, and highly metastatic., Conclusion: DAPK1 is highly expressed in sera and breast tissues of breast cancer patients than nonbreast cancer participants. The elevated expression of DAKP1 in circulation rather than in breast tissues makes it a candidate for use as a blood biomarker and potential use as therapeutic target in drug development., Competing Interests: The authors declare that they have no conflicts of interest regarding this manuscript., (Copyright © 2020 Benjamin Arko-Boham et al.)

- Abstract
Purpose: In a review of cancer incidence across continents (GLOBOCAN 2012), data sources from Ghana were classified as Frequencies, the lowest classification for inclusion, signifying the worst data quality for inclusion in the analysis. Recognizing this deficiency, the establishment of a population-based cancer registry was proposed as part of a broader cancer control plan., Methods: The registry was examined under the following headings: policy, data source, and administrative structure; external support and training; and definition of geographic coverage., Results: The registry was set up based on the Ghana policy document on the strategy for cancer control. The paradigm shift ensured subscription to one data collection software (CanReg 5) in the country. The current approach consists of trained registrars based in the registry who conduct active data abstraction at the departments and units of the hospital and pathologic services. To ensure good governance, an administrative structure was created, including an advisory board, a technical committee, and registry staff. External support for the establishment of the Accra Cancer Registry has come mainly from Stanford University and the African Cancer Registry Network, in collaboration with the University of Ghana. Unlike previous attempts, this registry has a well-defined population made up of nine municipal districts., Conclusion: The Accra Cancer Registry was established as a result of the lessons learned from failed previous attempts and aim to provide a model for setting up other cancer registries in Ghana. It will eventually be the focal point where all the national data can be collated.

- Abstract
Background: Endemic Burkitt lymphoma (eBL) is an aggressive B-cell lymphoma, which is a common childhood cancer in areas with intense transmission of Plasmodium falciparum parasites. Early and accurate diagnosis is a prerequisite for successful therapy, but it optimally involves advanced laboratory investigations. These are technologically demanding, expensive, and often difficult to implement in settings where eBL is prevalent. Diagnosis is thus generally based on clinical assessment and morphological examination of tumour biopsies or fine-needle aspirates (FNAs)., Methods: The purpose of the present study was to assess the accuracy of eBL diagnosis at two tertiary hospitals in Ghana. To that end, we studied FNAs from 29 eBL patients and 21 non-eBL lymphoma patients originally diagnosed in 2018. In addition, we examined 111 archival formalin-fixed and paraffin-embedded (FFPE) biopsies from Ghanaian patients originally diagnosed as eBL (N = 55) or non-eBL (N = 56) between 2010 and 2017. Availability-based subsets of samples were subjected to haematoxylin-eosin or Giemsa staining, C-MYC immunohistochemistry, and fluorescence in situ hybridisation (FISH) analysis of c-myc rearrangements., Results: We found a good correlation between original diagnosis and subsequent retrospective assessment, particularly for FNA samples. However, evidence of intact c-myc genes and normal C-MYC expression in samples from some patients originally diagnosed as eBL indicates that morphological assessment alone can lead to eBL over-diagnosis in our study area. In addition, several FFPE samples could not be assessed retrospectively, due to poor sample quality. Therefore, the simpler FNA method of obtaining tumour material is preferable, particularly when careful processing of biopsy specimens cannot be guaranteed., Conclusion: We conclude that the accuracy of eBL diagnostic tools available in Ghana is generally adequate, but could be improved by implementation of additional pathology laboratory investigations. Improved attention to adequate preservation of archival samples is recommended.

- Abstract
Background: Schistosomiasis is the second major human parasitic disease next to malaria, in terms of socioeconomic and public health consequences, especially in sub-Saharan Africa. Schistosoma haematobium ( S. haematobium ) is a trematode and one of the species of Schistosoma that cause urogenital schistosomiasis (urinary schistosomiasis). Although the knowledge of this disease has improved over the years, there are still endemic areas, with most of the reported cases in Africa, including Ghana. Not much has been done in Ghana to investigate cytological abnormalities in individuals within endemic communities, although there are epidemiologic evidences linking S. haematobium infection with carcinoma of the bladder., Aim: The aim of this study was to identify microscopic and cytological abnormalities in the urine deposits of S. haematobium -infected children., Methodology: Three hundred and sixty-seven (367) urine samples were collected from school children in Zenu and Weija communities. All the samples were examined microscopically for the presence of S. haematobium eggs, after which the infected samples and controls were processed for cytological investigation., Results: S. haematobium ova were present in 66 (18.0%) out of the 367 urine samples. Inflammatory cells (82%, 54/66), hyperkeratosis (47%, 31/66), and squamous cell metaplasia (24%, 16/66) were the main observations made during the cytological examination of the S. haematobium -infected urine samples., Conclusion: Cytological abnormalities in S. haematobium -infected children may play an important role in the severity of the disease, leading to the possible development of bladder cancer in later years, if early attention is not given. Therefore, routine cytological screening for urogenital schistosomiasis patients (especially children) at hospitals in S. haematobium -endemic locations is recommended., Competing Interests: The authors declare that there are no conflicts of interest regarding the publication of this article., (Copyright © 2019 Patience B.

- Abstract
The prognosis of gastric and oesophageal adenocarcinoma remains generally poor. However, mounting evidence suggests a positive role of human epidermal growth factor receptor-2 (HER-2) expression in the prognosis of patients with these cancers. In this work, the patterns of HER-2 protein expression were determined in patients with gastric or oesophageal adenocarcinoma. Retrospectively, we reviewed records of gastric and oesophageal biopsies received from 2008 to 2012 and their corresponding archived formalin-fixed paraffin-embedded tissue blocks selected for immunohistochemical analysis. The prevalence of gastric and oesophageal adenocarcinomas and their association with HER-2 protein overexpression were evaluated. Gastric adenocarcinoma made up 18.79% of the gastric biopsies reviewed, and majority of these cancers occurred in males. Regarding the tumour type, HER-2 overexpression was common in the intestinal subtype compared to the diffuse type. Although squamous cell carcinoma was observed to be the commonest (31%) tumour type in the oesophagus compared to adenocarcinoma (8.79%), HER-2 was overexpressed in 42.9% of oesophageal adenocarcinomas, like gastric adenocarcinoma (41.4%). There is a high prevalence of gastric and oesophageal adenocarcinoma, with significant overexpression of HER-2 in these tumours, a window of hope for the management of patients with these cancers.

- Abstract
Background: Helicobacter pylori infection is prevalent in Ghana. The development of gastro-duodenal disease is dependent on virulence of the infecting strain, host susceptibility and environmental factors. Helicobacter pylori cagA and vacA strains induce more inflammation, ulceration and oncogenesis. Here, for the first time we present data on H. pylori cagA and vacA genes and their association with gastro-duodenal disease in Ghana. A total of 159 patients with dyspepsia at Korle-Bu Teaching Hospital, Accra, were investigated for H. pylori with urease-CLO, of which 113 (71.1%) were positive. Genomic DNA was extracted from antral biopsies using QIAGEN DNeasy kit. Detection of H. pylori vacA and cagA genes were determined by PCR as previously described., Results: In total, 110 (69.2%) vacAs1, 71 (44.7%) vacAm1, 35 (22.0%) vacAm2, 77 (48.4%) cagA-(hydrophilic region) and 109 (68.6%) cagA-(internal duplication region) were detected. In multivariate analysis, duodenal ulcer was more likely than other diagnoses to have detectable cagA-(hydrophilic region) (OR 3.1 CI 1.2-7.9) or vacAs1m1 (OR 6.5 CI 1.2-34.0)., Conclusions: Majority of biopsies were colonized with H. pylori harboring both cagA and vacA. H. pylori cagA-(internal duplication region) was more prevalent than cagA-(hydrophilic region). Duodenal ulcer was more likely than other diagnoses to have detectable cagA-(hydrophilic region) or vacAs1m1.

- Abstract
Background: Ovarian tumours are a leading cause of death in Ghana. Even though geographical and racial differences exist in the frequency, types and age distribution of primary ovarian tumours, information about the clinical and pathological characteristics of ovarian tumours in Ghana and its neighboring countries is scanty. We determined the frequency, age distribution, histopathological types and clinical features of primary ovarian tumours diagnosed at the Korle-Bu Teaching Hospital in Ghana to aid in the management of patients., Method: All pathology records of ovarian tumours diagnosed from January 2001 to December 2010 were reviewed. Histopathologically, tumours were classified according to the then World Health Organization 1999 classification. Biographical and clinical data of patients were also collected and entered into Epi-info to determine the frequency, age distribution and other clinical features of the types of ovarian tumour., Results: Seven hundred and six ovarian tumours were studied. Germ cell tumours were the most common (41.9%), with mean age of occurrence being 30.7 years (SD 12.7), they were dominated by mature teratomas (39.2%). Surface epithelial tumours were second, and commonly occurred in women aged 35-44years, 77 (26.8%). Sex cord stromal tumours followed with mean age of occurrence of 40.2 years (SD 17.9). The most common malignant tumours were surface epithelial (52.1%) dominated by serous carcinomas with mean age 50.1 years. Most patients (47.7%) presented within 1 month of onset of symptoms, feeling a lower abdominal mass (38.5%)., Conclusion: The most common primary ovarian tumours in this study are Germ cell tumours, dominated by mature teratomas. Adenocarcinomas are mostly serous and occur in younger women compared to findings of other Western studies. The single most common malignant ovarian tumour in children and adolescents is Burkitt lymphoma. Patients who develop ovarian tumours have no specific symptoms or signs at presentation, to aid early diagnosis.

- Abstract
Nasopharyngeal carcinomas (NPC) are endemic in Far East Asia and commonly harbour Epstein-Barr virus (EBV) which is known to serve as a key oncogenic promoter. Human papillomavirus (HPV) is known to contribute to the pathogenesis of NPC. However, in Ghana these two viruses have not been linked to NPC prevalence. This study was designed to determine the HPV genotypes and EBV involved in NPC tissue biopsies. A retrospective study design involving 72 formalin-fixed paraffin-embedded tissue (FFPET) samples of NPC from 2006 to 2012 were retrieved from the Department of Pathology, University of Ghana School of Biomedical and Allied Health Sciences. Sections were taken for histological analysis and for DNA lysate preparation. The DNA lysates were subjected to polymerase chain reaction (PCR) analysis to determine the presence of HPV genotypes and EBV. HPV specific primers were used to type for fourteen HPV genotypes (HPV-16, 18, 6/11, 31, 33, 35, 44, 42, 43, 45, 56, 52, 58, and 59). Out of the 72 NPC biopsies analyzed by PCR, EBV DNA was present in 18 (25%) cases and HPV DNA in 14 (19.23%). High risk HPV (HR-HPV) genotypes 18 and 31 were associated with the NPC. There were 3 (4.2%) cases of coinfection by both viruses. The EBV DNA present in the undifferentiated variant of the NPC and the histopathology of the NPC in Ghana is similar to the type described in endemic areas.

- Abstract
Background: The human immunodeficiency virus (HIV) infection usually infects persons in the reproductive age group (15-49 years), but elderly people are also susceptible. Many people in sub-Saharan Africa including Ghana believe that elderly people are not at risk for HIV. Despite numerous reports of the high prevalence of HIV infection among the elderly worldwide, there are no from Ghana. This work determined the sero-prevalence of HIV infection and risk factors for its transmission among 1,100 hospitalized elderly people at the Korle Bu Teaching Hospital (KBTH), Accra, Ghana., Methods: Subjects voluntarily completed a risk-factor questionnaire and provided a blood specimen for HIV testing., Results: Of the study participants, 440 were male (mean age: 64 ± 10.55 years), and 660 were female (mean age: 63 ± 9.51 years). The overall HIV-1 sero-prevalence among the subjects was 4.18 % ( n = 46). On multivariate analysis, there was no statistical significance between the socio-demographics or risk factors and the HIV status of the participants., Conclusion: The results suggest high prevalence of HIV-1 among hospitalized elderly people at KBTH, recommending the need to include the elderly in HIV/AIDS testing, prevention, and control programmes., Trial Registration: Trial registration number: MS-Et/M.9 - p4.10/2012-2013. Registered: 10th April, 2013.

- Abstract
To determine the histopathologic types, frequency of occurrence, age distribution, presenting signs, and symptoms of ovarian tumors in children and adolescents diagnosed at the Korle-Bu Teaching Hospital all histopathology slides and request cards of ovarian tumors diagnosed in subjects aged, 0 to 19 yr over a 10-yr period (2001-2010) were reviewed. Biographical and clinical data of the patients were collected. The results were entered into Epi-info to determine the frequency of various ovarian tumors in different age groups and their association with presenting signs and symptoms. A total of 67 (9.5%) ovarian tumors were diagnosed in patients aged 0 to 19 yr of a total of 706 diagnosed in all age groups during the period. The majority [44 (65.7%)] were germ cell tumors, the commonest being mature cystic teratoma. Burkitt lymphoma was the single most common malignant tumor, comprising 6(9%) of all the tumors, although as a group malignant germ cell tumors were still the most common malignant ovarian tumors in children and adolescents. Although germ cell tumors were the most common tumors in this age group (both benign and malignant), Burkitt lymphoma, a peculiar malignant tumor in this subregion, was the single most common malignant tumor of the ovary.

- Abstract
Background: There is a high prevalence of gastro-duodenal disease in sub-Saharan Africa. Peptic ulcer disease in dyspeptic patients, 24.5%, was comparable to prevalence of gastro-duodenal disease among symptomatic individuals in developed countries (12 - 25%). Limited data exists regarding its associated risk factors despite accumulating evidence indicating that gastroduodenal disease is common in Ghana., Objectives: This study investigates risk factors associated with gastro-duodenal disease at the Korle-Bu Teaching Hospital, Accra, Ghana., Methods: This study utilized a cross-sectional design to consecutively recruit patients referred with upper gastro-intestinal symptoms for endoscopy. The study questionnaire was administered to study participants. Helicobacter pylori infection was confirmed by rapid-urease examination at endoscopy., Results: Of 242 patients sampled; 64 had duodenal ulcer, 66 gastric ulcer, 27gastric cancer and 64 non-ulcer dyspepsia. Nineteen (19) had duodenal and gastric ulcer while 2 had gastric ulcer and cancer. A third (32.6%) of patients had history of NSAID-use. H. pyloriwas associated with gastric ulcer (p=0.033) and duodenal ulcer (p=0.001). There was an increased prevalence of duodenal ulcer in H. pylori-infected patients taking NSAIDs, P=0.003., Conclusion: H. pylori was a major risk factor for peptic ulcer disease. However, NSAID-related gastro-duodenal injury has been shown to be common in H. pylori infected patients. It highlights the need for awareness of the adverse gastro-intestinal effects in a H. pylori endemic area.

- Abstract
To determine the histopathological types, age distribution, presenting signs and symptoms of ovarian cancers diagnosed at the Korle-Bu Teaching Hospital, Ghana. All histopathology slides and request cards of ovarian cancers diagnosed over a ten-year period (2001 to 2010) were reviewed and the cancers classified according to the World Health Organization 1999 classification. Biographical and clinical data of the patients were collected and results entered into Epi-info to determine the frequency, age distribution and clinical presentation of the various types of ovarian cancer. There were 192 (27.2%) ovarian cancers out of 706 ovarian tumours. Epithelial cancers were the most common: 100 (52.1%), followed by sex cord stromal cancers 66 (34.4%). Majority of epithelial cancers were serous adenocarcinomas (71/100) while most sex cord stromal cancers were adult granulosa cell tumours 46 (69.7%). The mean age of patients with adenocarcinoma was 49 years while that of the 46 adult granulosa cell tumours was 46.5 years. Patients present with varying combinations of symptoms and signs and ovarian cancers present at an earlier age compared to other populations, with the age of presentation being slightly lower for sex cord stromal cancers compared to adenocarcinomas. There are no specific symptoms or signs associated with ovarian cancer at presentation, to assist with diagnosis.

- Abstract
Breast cancers that have negative or extremely low expression of estrogen receptor and progesterone receptor and non-amplification of human epidermal growth factor receptor-2 (HER2)/neu are termed triple-negative breast cancer (TNBC). The majority of TNBC tumors belong to the biologically aggressive basal subtype, and they cannot be managed with targeted endocrine or anti-HER2/neu agents. In western, high resource environments, risk factors for TNBC include younger age at diagnosis and hereditary susceptibility. Women of African ancestry in the United States and in continental Africa have higher frequencies of TNBC, prompting speculation that this risk may have an inherited basis and may at least partially explain breast cancer survival disparities related to racial/ethnic identity. Efforts to document and confirm the breast cancer burden of continental Africa have been hampered by the limited availability of registry and immunohistochemistry resources. Our goal was to evaluate the breast cancers diagnosed in one of the largest health care facilities in western Africa, and to compare the frequencies as well as risk factors for TNBC versus non-TNBC in this large referral tertiary hospital. The Korle Bu Teaching Hospital is affiliated with the University of Ghana and is located in Accra, the capital of Ghana. We conducted an institutional, Department of Pathology-based review of the breast cancer cases seen at this facility for the 2010 calendar year, and for which histopathologic specimens were available. The overall study population of 223 breast cancer cases had a median age of 52.4 years, and most had palpable tumors larger than 5 cm in diameter. More than half were TNBC (130; 58.3%). We observed similar age-specific frequencies, distribution of stage at diagnosis and tumor grade among cases of TNBC compared to cases of non-TNBC. Ghanaian breast cancer patients tend to have an advanced stage distribution and relatively younger age at diagnosis compared to Caucasian Americans and African Americans. The triple-negative molecular marker pattern was the most common subtype of breast cancer seen among this sample of Ghanaian women, regardless of age, tumor grade, or stage of diagnosis. Research into the molecular pathogenesis of TNBC may help elucidate the reasons for its increased prevalence among women with African ancestry., (© 2015 Wiley Periodicals, Inc.)

- Abstract
The objective of this study was to analyze nephrectomies performed in adults over a 12-year period at the Korle Bu Teaching Hospital, Accra and to compare our findings with reports from other institutions. In this retrospective study, medical records of 97 consecutive adult patients who underwent nephrectomy from January 2000 to December 2011 were reviewed. The parameters extracted included the patients' age, gender, indication for nephrectomy and the side of nephrectomy. Also considered were the histology of the nephrectomy specimen and the peri-operative mortality. The data were analyzed using the Statistical Package for Social Sciences for Windows (Version 19.0). Of the 97 nephrectomies performed, 62 were performed for suspected malignant renal tumors and 35 were performed for clinically benign renal conditions. Malignancy was confirmed in 85.5% (53/62) of the suspected cases. The mean age of this group was 52.2 ± 15.5 years and the male to female ratio was 1:0.9. Thirty-two tumors (60.4%) were in the right kidney and 21 (39.6%) tumors were in the left kidney; the mean tumor size was 16.8 ± 4.0 cm. The predominant presenting complaints included flank pain (67.9%), flank mass (50.9%) and hematuria (24.5%). In one case (1.9%), the renal mass was found incidentally. Among patients who had benign disease, non-functioning kidney due to renal cystic disease was the most common lesion (11/44; 25.0%). A peri-operative mortality rate of 3.1% was recorded. Our study suggests that malignant renal tumors constitute the main indication for nephrectomy in our institution. Non-functioning kidney due to renal cystic disease was the most common benign renal indication for nephrectomy.

- Abstract
Introduction: Helicobacter pylori is a gram-negative urease-producing bacterium causally linked with gastritis, peptic ulcer disease and gastric adenocarcinoma. Infection is more frequent and acquired at an earlier age in developing countries compared to European populations. The incidence of Helicobacter pylori infection in dyspeptic Ghanaian patients was 75.4%. However, epidemiological factors associated with infection vary across populations., Methods: This study used a cross-sectional design to consecutively sample dyspeptic patients at the Endoscopy Unit of the Korle-Bu Teaching Hospital, Accra between 2010 and 2012. The study questionnaire elicited their epidemiological clinical characteristics. Helicobacter pylori infection was confirmed by rapid-urease examination of antral biopsies at upper Gastro-intestinal endoscopy., Results: The sample population of dyspeptic patients attending the Endoscopy Unit for upper GI endoscopy yielded 242 patients of which 47.5% were females. The age distribution of H. pylori-infection was even across most age - groups, ranging from 69.2% (61 - 70) years to 80% (21 - 30) years. Helicobacter pylori prevalence decreased across areas mapping to the three residential classes in accordance with increasing affluence with rural areas having the highest prevalence. The unemployed and patients in farming had relatively high Helicobacter pylori infection rates of 92.3% and 91.7% respectively., Conclusion: Helicobacter pylori is endemic in Ghana but the persistently high prevalence across age groups despite significant community anti-microbial use suggests likely recrudescence or re-infection from multiple sources in a developing country. Socio-cultural factors such as residential class and farming may be facilitating factors for its continued prevalence.

- Abstract
Background: Squamous cell carcinoma originating from the oral cavity, lip, larynx and pharynx are grouped under head and neck squamous cell carcinomas (HNSCC)., Objective: To report on human papillomavirus (HPV) genotypes involved in HNSCC., Study Design: A retrospective review of archival HNSCC specimens and patient demographic and clinical data accessioned between January, 2007 and December, 2009 in the Department of Pathology, Korle-Bu Teaching Hospital, Accra, Ghana., Results: Cases from 58 males and 20 females included 29 from the oral cavity, 33 from the larynx, 11 from the pharynx and 5 from the parotid gland. HPV DNA was found in 15 (19.23%) of the tumors with 12 being HPV-16, 2 HPV-18 and 1 dual infection with HPV-16 and HPV-18, giving HPV-16 prevalence of 86.7%. Higher prevalence of HPV DNA was found in males than females. There was a trend towards subjects younger than 58 years being more likely to have HPV-positive tumors.The 15 HPV-positive cases were distributed in location as 8 of 33 (24.2%) from the larynx, 4 of 29 (13.8%) from the oral cavity, and 2 of 11 (18.2%) from the pharynx and 1 of 5 (20%) from the parotid gland., Conclusion: Oncogenic HPV infection was found in 19.23% of HNSCCs, with genotype 16 predominating. HPV-related HNSCC tended to occur at younger age compared to non-HPV-related HNSCC. The commonest site for HPV-associated HNSSC in Ghana is the larynx, rather than the oropharynx as reported in other studies. Host factors may be responsible for the site difference and more work is required to further elucidate this.

Background and Objectives: The presentation of the different histopathologic subtypes of adenocarcinoma of the large bowel vary within the colorectum and appears to impact on treatment. This study evaluated the relationships between the clinical features of adenocarcinoma of the large bowel, the histopathologic subtypes, and treatment., Methods: Patients with adenocarcinoma of the large bowel presenting to the Korle Bu Teaching Hospital from January 1997 to December 2011 were studied., Results: The study involved 579 patients: 310 (53.5%) males and 269 (46.5%) females, median age 58 years. Right colon cancers were 170 (29.4%), left colon 128 (22.1%), and rectum 281 (48.5%). Well-differentiated cancers were 254 (43.3%), moderately differentiated 178 (30.3%), mucinous 90 (14.8%), anaplastic 44 (7.5%), and signet-ring cell cancer 13 (2.2%). The mean ages across the histologic types were unequal, F-test 8.34, P-value 0.0005, with patients with mucinous and signet-ring cancers much younger. Mucinous cancers were predominantly in the right colon while signet-ring cell cancers were mostly in the rectum. Well- and moderately differentiated cancers presented at early stage than anaplastic and signet-ring cell cancers, P ∼ 0.01 and P < 0.03, respectively. The overall resection rate was 346 (59.8%) with rectal cancer having very low resection rate of 81 (28.8%)., Conclusion: Adenocarcinoma of the large bowel was predominantly in the rectum and in patients who were 50 years and older and were mostly well or moderately differentiated cancers., (© 2013 Wiley Periodicals, Inc.)

- Abstract
Reports of spindle cell sarcoma in the tongue are very rare, and seldom in the child. We report a five-year-old male patient who presented with a massive lesion on the right side of the tongue. This was surgically excised and histologically diagnosed as a Spindle cell Sarcoma. Results of bone marrow aspiration further revealed that about 16% of his bone marrow was infiltrated with abnormal pleomorphic vacuolated cells with bluish cytoplasm, consistent with rhabdomyosarcoma (RMS) cells. The child was treated with surgery and chemotherapy with good initial response, but then died after one year following a relapse.

- Abstract
Objective: Data on maternal mortality varies by region and data source. Accurate local-level data are essential to appreciate its burden. This study uses autopsy results to assess maternal mortality causes in southern Ghana., Methods: Autopsy log books of the Department of Pathology, Korle-Bu Teaching Hospital Mortuary were reviewed from 2004 through 2008 for pregnancy related deaths. Data were entered into a database and analyzed using SPSS statistical software (Version 19)., Results: Of 5,247 deaths among women aged 15-49, 12.1% (634) were pregnancy-related. Eighty one percent of pregnancy-related deaths (517) occurred in the community or within 24 hours of admission to a health facility and 18.5% (117) occurred in a health facility. Out of 634 pregnancy-related deaths, 79.5% (504) resulted from direct obstetric causes, including: haemorrhage (21.8%), abortion (20.8%), hypertensive disorders (19.4%), ectopic gestation (8.7%), uterine rupture (4.3%) and genital tract sepsis (2.5%). The remaining 20.5% (130) resulted from indirect obstetric causes, including: infections outside the genital tract, (9.2%), anemia (2.8%), sickle cell disease (2.7%), pulmonary embolism (1.9%) and disseminated intravascular coagulation (1.3%). The top five causes of maternal death were: haemorrhage (21.8%), abortion (20.7%), hypertensive disorders (19.4%), infections (9.1%) and ectopic gestation (8.7%)., Conclusion: Ghana continues to have persistently high levels of preventable causes of maternal deaths. Community based studies, on maternal mortality are urgently needed in Ghana, since our autopsy studies indicates that 81% of deaths recorded in this study occurred in the community or within 24 hours of admission to a health facility.

- Abstract
Objectives: To evaluate breast cancer in Ghanaian women and to compare these findings with those of previous studies by using histopathologic data., Methods: A review of all breast cancer specimens from January 2005 through December 2009 in our institution was conducted., Results: Of 4,109 female breast specimens reviewed, 1,342 (32.7%) were malignant. Mean (SD) patient age was 50.3 (13.3) years, and mean size of the primary tumors was 4.5 cm. Eighteen (1.3%) specimens were malignant phyllodes tumors. Significant positive associations were found between size of the primary tumor and histologic type (P = .01), histologic grade (P = .001), nodal involvement (P < .001), and TNM stage (P < .001)., Conclusions: More than 3 decades after the first publication of breast cancer in Ghanaian women, patients are still presenting with large clinically and histologically advanced invasive cancers.

- Abstract
Unlabelled: Goitre in the West African sub-region is caused by iodine deficiency and goitrogens in the diet. Supplementary iodine nutrition on a mass scale was started in Ghana in 1996. In areas where iodine deficiency have been corrected the histological pattern of goitre changes and this influences surgical decision making. Data on the histological types of goitre in our institution is lacking., Objective: To define the histopathological types of goitre in this initial period of iodine supplementation and relate this to the types of thyroid surgeries that were performed., Methods: It was a prospective study of consecutive patients who underwent thyroidectomy from January 2003-December 2007. Descriptive statistics was employed in analyzing the data, Results: Five hundred and twenty eight cases were studied made up of 470 (89%) females and 58 (11%) males with mean age of 41.98 yrs, SD ± 12.90 yrs. The excised mean thyroid tissue weight was 161.4 g, SD ± 116.3 yrs. Hyperplastic goitres were 373 (70.7%), toxic goitre 70 (13.3%), adenoma 37 (7.0%), carcinoma 25 (4.7%) and thyroiditis 23 (4.4%). Papillary carcinoma accounted for 56% (14) cancers. Subtotal thyroidectomy was performed in 278 (52.7%) of patients, near total thyroidectomy 107 (20.3%), lobectomy 98 (18.6%),total thyroidectomy 24 (4.5%), excision or completion thyroidectomy 20 (3.8%) and de-bulking 1 patient. Overall, complications occurred in 32 patients (6.1%) and were made up mostly of haemorrhage in 10 (1.9%), Hypocalcaemia 10 (1.9%), unilateral Recurrent Laryngeal Nerve(RLN) injury 3 (0.57%), Tracheal collapse 3 (0.57%) and Bilateral RLN injury 2 (0.4%)., Conclusion: The introduction of iodine supplementation on a mass scale in Ghana is yet to have its fullest impact on thyroid diseases. Goitres are still large and cause pressure effects. Toxic, inflammatory and malignant goitres are gaining prominence, and surgery for malignant goitre was oncologically inadequate.Near total thyroidectomy is recommended as the minimum surgery to avert the need for completion thyroidectomies in view of the lack of preoperative pathological diagnosis of thyroid lesions.

- Abstract
Pregnancy in sickle cell disease (SCD) patients is associated with increased risk of maternal and fetal mortality. This study determines pregnancy outcomes among women with SCD delivering at Korle-Bu Teaching Hospital, Accra, Ghana. Nine hundred sixty (960) medical records of pregnant women (131 HbSS, 112 HbSC, and 717 comparison group) from 2007 to 2008 were reviewed. The HbSS women were at increased risk of eclampsia (adjusted odds ratio [AOR] = 10.56, 95% confidence interval [CI] = 3.60-30.96, P < 0.001), intrauterine growth restriction (AOR = 4.00, 95% CI = 1.38-11.64, P = 0.011), and placenta previa (AOR = 22.03, 95% CI = 9.87-49.14, P < 0.001) compared with the comparison group. The HbSC women had increased risk for intrauterine fetal death (AOR = 3.38, 95% CI = 1.15-9.96, P = 0.027) and decreased risk of delivering low birth weight babies (AOR = 0.21, 95% CI = 0.06-0.73, P = 0.014). Women with SCD in Ghana are at a greater risk of morbidity and mortality in pregnancy compared with women without hemoglobinopathies. Improved maternal and fetal outcomes in Ghanaian women with SCD can be achieved through effective intervention by health care providers with thorough knowledge about predisposing factors toward adverse outcomes.

- Abstract
The effectiveness of intermittent preventive treatment during pregnancy with sulfadoxine-pyrimethamine (IPTp-SP) against malaria and anemia is unclear because of the spread of SP-resistant Plasmodium falciparum. This study evaluates the effectiveness of IPTp-SP among pregnant women attending the antenatal clinic at Korle-Bu Teaching Hospital in Accra, Ghana. A cross-sectional study comparing malaria and anemia prevalence among pregnant women using IPTp-SP with non-IPTp-SP users was conducted during June-August 2009. A total of 363 pregnant women (202 of IPTp users and 161 non-IPTp users) were recruited. A total of 15.3% of IPTp users had malaria compared with 44.7% of non-IPTp users (P < 0.001). A total of 58.4% of non-IPTp users were anemic compared with 22.8% of IPTp users (P < 0.001). When we controlled for other variables, the difference in the prevalence of malaria (odds ratio = 0.18, 95% confidence interval = 0.08-0.37) and anemia (odds ratio = 0.20, 95% confidence interval = 0.12-0.34) remained significant. The recommended IPTp-SP regimen is useful in preventing malaria and anemia among pregnant women in Ghana.

- Abstract
Background: Clinical experience and earlier studies indicate that the number of colorectal cancer cases seen annually in the Accra metropolis is increasing., Objective: This study was aimed at providing a current update on colorectal cancer in Accra, Ghana., Methods: A prospective study of confirmed cases of colorectal cancer diagnosed from January 1997- December 2007., Results: Three hundred and fifty-nine colorectal cancer cases were studied. Males were 192(53.5%) and females 167(46.5%) with an annual incidence of 32.6 new cases. The crude incidence rates were 12.53, 9.87 and 11.18 per 100,000 population for males, females and overall respectively. Rectal bleeding 185(51.1%), abdominal mass 76(21.1%), intestinal obstruction 62(17.3%), intestinal perforation nine (2.5%) and iron deficiency anaemia nine (2.5%) cases were the main presentations. There were 168 (46.8%) rectal and 191(53.2%) colon tumours. Two hundred and thirty-one patients had laparotomy with 225 resections, and 128 patients for various reasons did not undergo surgery. The Astler Coller stages of the tumours at diagnosis were C2 84(36.7%), C1 53(22.1%), B2 49(21.4%), D 17(7.4%), B1 14(6.1%) and A 12(5.1%) cases. Adenocarcinoma was the commonest histological type 321(89.4%), with the majority either well-differentiated (62.5%) or moderately well-differentiated (25.6) carcinomas. Poorly differentiated carcinomas accounted for 28 cases (7.8%). Post-operative mortality was 6.1%. Long term survival could not be assessed as the majority of patients were lost to follow up., Conclusion: The incidence of colorectal cancer has increased over the last four decades in tandem with an aging population of Accra with adenocarcinoma as the predominant histological type.

- Abstract
Objective: To determine the correlates of hepatitis E virus infection (HEV) in a sample of persons who work with pigs., Design: Cross-sectional study., Setting: Three pig farms in the Greater Accra Region of Ghana., Subjects: Persons who work with pigs seen at the selected pig farms between the months of January and May 2008., Results: One hundred and five persons who work with pigs voluntarily completed a risk-factor questionnaire and provided blood samples for unlinked anonymous testing for the presence of antibodies to HEV. The median age of participants was 36.5 +/- 15.0 years (range 12-65 years). Of the 105 subjects tested, HEV seroprevelance was 38.1%. On multivariate analysis, the independent determinants of HEV infection were being employed on the farm for less than six months (odds ratio (OR) 9.1; 95% confidence interval (95% CI) 1.0-81.4 and having piped water in the household and/or on the farm (OR 3.9; 95% CI 0.4-90.8)., Conclusion: Consistent with similar studies worldwide, the results of our studies revealed a high prevalence of HEV infection in persons who work with pigs. Further studies need to be done to isolate, characterise the virus and define the clinical and epidemiological significance of HEV infection in this population.

- Abstract
Background: This study was aimed at estimating the human papillomavirus (HPV) prevalence and its determinants among a sample of Ghanaian women., Design: Cross-sectional observational study., Setting: Gynaecology outpatient clinic of the Korle-Bu Teaching Hospital, Accra, Ghana; the largest tertiary care gynaecology outpatient clinic in Ghana., Participants: Convenient sample of 75 consenting women visiting the clinic., Methods: Information was obtained through personal interviews using structured questionnaire, Pap smears obtained, and laboratory testing of cervical exfoliated cells was performed. HPV DNA was detected using a GP5+/6+ polymerase chain reaction assay. These data were analyzed using both univariate and bivariate techniques., Results: The mean age of participants was 33.3 years (standard deviation, 9.2) and the percentage of lifetime monogamy was 21.3%. The crude HPV DNA prevalence was 10.7%. Unlike most populations studied so far, HPV prevalence was high not only among young women, but also in middle and old age. Independent HPV determinants were being illiterate (prevalence odds ratio [POR], 13.9; 95% confidence interval [95%CI], 1.9-100) and reporting more than three lifetime sexual partners (POR, 4.6; 95% CI, 1.0-22.2)., Conclusions: The study indicates a high crude prevalence of HPV in a largely polygamous Ghanaian population with a high crude prevalence in older age groups, which may be a distinctive feature of polygamous populations where HPV transmission continues into middle age and cervical cancer incidence is very high.

- Abstract
Background: Plasmodium falciparum can cause a diffuse encephalopathy known as cerebral malaria (CM), a major contributor to malaria associated mortality. Despite treatment, mortality due to CM can be as high as 30% while 10% of survivors of the disease may experience short- and long-term neurological complications. The pathogenesis of CM and other forms of severe malaria is multi-factorial and appear to involve cytokine and chemokine homeostasis, inflammation and vascular injury/repair. Identification of prognostic markers that can predict CM severity will enable development of better intervention., Methods: Postmortem serum and cerebrospinal fluid (CSF) samples were obtained within 2-4 hours of death in Ghanaian children dying of CM, severe malarial anemia (SMA), and non-malarial (NM) causes. Serum and CSF levels of 36 different biomarkers (IL-1beta, IL-1ra, IL-2, IL-4, IL-5, IL-6, IL-7, IL-8, IL-9, IL-10, IL-12 (p70), IL-13, IL-15, IL-17, Eotaxin, FGF basic protein, CRP, G-CSF, GM-CSF, IFN-gamma, TNF-alpha, IP-10, MCP-1 (MCAF), MIP-1alpha, MIP-1beta, RANTES, SDF-1alpha, CXCL11 (I-TAC), Fas-ligand [Fas-L], soluble Fas [sFas], sTNF-R1 (p55), sTNF-R2 (p75), MMP-9, TGF-beta1, PDGF bb and VEGF) were measured and the results compared between the 3 groups., Results: After Bonferroni adjustment for other biomarkers, IP-10 was the only serum biomarker independently associated with CM mortality when compared to SMA and NM deaths. Eight CSF biomarkers (IL-1ra, IL-8, IP-10, PDGFbb, MIP-1beta, Fas-L, sTNF-R1, and sTNF-R2) were significantly elevated in CM mortality group when compared to SMA and NM deaths. Additionally, CSF IP-10/PDGFbb median ratio was statistically significantly higher in the CM group compared to SMA and NM groups., Conclusion: The parasite-induced local cerebral dysregulation in the production of IP-10, 1L-8, MIP-1beta, PDGFbb, IL-1ra, Fas-L, sTNF-R1, and sTNF-R2 may be involved in CM neuropathology, and their immunoassay may have potential utility in predicting mortality in CM.

- Abstract
SummaryAlthough endocrine causes of secondary hypertension are relatively uncommon, medical practitioners must maintain a high index of suspicion for them in certain categories of patients. Such patients include young individuals, those with difficult-to-treat hypertension and those presenting with symptoms, clinical signs and/or laboratory parameters well-known to be associated with Cushing's syndrome, Conn's syndrome or phaeochromocytoma.This paper reports on 5 patients identified over a 2-year period with various hormonally-active adrenal adenomas causing hypertension in an environment where, hitherto, the occurrence of these conditions was generally thought to be rare. Aspects of the patients' histories, examination and laboratory findings that drew attention to the possibility of the diagnosis in each case are highlighted, as are the confirmatory investigations and management methods used by a multidisciplinary team of medical practitioners. The clinical outcome with appropriate treatment of adrenal-related hypertension is good and can result in significant cost savings in the long term.
