RESUMO

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.

RESUMO

INTRODUCTION: Ghana adopted the revised WHO recommendation on intermittent preventive treatment in pregnancy using sulfadoxine-pyrimethamine (IPTp-SP) in 2012. This study has assessed the effectiveness and safety of this policy in Ghana. METHODS: A total of 1926 pregnant women enrolled at antenatal care (ANC) clinics were assessed for birth outcomes at delivery, and placental histology results for malaria infection were obtained from 1642 participants. Association of reduced placental or peripheral malaria, anaemia and low birth weight (LBW) in women who received ≥4 IPTp-SP doses compared with 3 or ≤2 doses was determined by logistic regression analysis. RESULTS: Among the 1926 participants, 5.3% (103), 19.2% (369), 33.2% (640) and 42.3% (817) of women had received ≤1, 2, 3 or ≥4 doses, respectively. There was no difference in risk of active placental malaria (PM) infection in women who received 3 doses compared with ≥4 doses (adjusted OR (aOR) 1.00, 95% CI 0.47 to 2.14). The risk of overall PM infection was 1.63 (95% CI 1.07 to 2.48) in 2 dose group and 1.06 (95% CI 0.72 to 1.57) in 3 dose group compared with ≥4 dose group. The risk of LBW was 1.55 (95% CI 0.97 to 2.47) and 1.06 (95% CI 0.68 to 1.65) for 2 and 3 dose groups, respectively, compared with the ≥4 dose group. Jaundice in babies was present in 0.16%, and 0% for women who received ≥4 doses of SP. CONCLUSION: There was no difference in the risk of PM, LBW or maternal anaemia among women receiving 3 doses compared with ≥4 doses. Receiving ≥3 IPTp-SP doses during pregnancy was associated with a lower risk of overall PM infection compared with 2 doses. As there are no safety concerns, monthly administration of IPTp-SP offers a more practical opportunity for pregnant women to receive ≥3 doses during pregnancy.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

PURPOSE: Cancer of the prostate (CaP) is the leading cancer among men in sub-Saharan Africa (SSA). A substantial proportion of these men with CaP are diagnosed at late (usually incurable) stages, yet little is known about the etiology of CaP in SSA. METHODS: We established the Men of African Descent and Carcinoma of the Prostate Network, which includes seven SSA centers partnering with five US centers to study the genetics and epidemiology of CaP in SSA. We developed common data elements and instruments, regulatory infrastructure, and biosample collection, processing, and shipping protocols. We tested this infrastructure by collecting epidemiologic, medical record, and genomic data from a total of 311 patients with CaP and 218 matched controls recruited at the seven SSA centers. We extracted genomic DNA from whole blood, buffy coat, or buccal swabs from 265 participants and shipped it to the Center for Inherited Disease Research (Baltimore, MD) and the Centre for Proteomics and Genomics Research (Cape Town, South Africa), where genotypes were generated using the UK Biobank Axiom Array. RESULTS: We used common instruments for data collection and entered data into the shared database. Double-entered data from pilot participants showed a 95% to 98% concordance rate, suggesting that data can be collected, entered, and stored with a high degree of accuracy. Genotypes were obtained from 95% of tested DNA samples (100% from blood-derived DNA samples) with high concordance across laboratories. CONCLUSION: We provide approaches that can produce high-quality epidemiologic and genomic data in multicenter studies of cancer in SSA.

RESUMO

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.

RESUMO

Basidiobolomycosis is an uncommon chronic deep fungal infection in which gradually enlarging granulomas form, usually in the subcutaneous fat tissues of the limbs, chest or trunk of immunocompetent hosts, primarily children and young adults. It is caused by the fungus Basidiobolus ranarum. Definitive diagnosis is by microscopy and histopathology. Effective treatments include ketoconazole, itraconazole, potassium iodide and co-trimoxazole. A 3 year old girl presented with ulcerations on the right thigh for one month, and painful swelling of the right leg and right buttock for six months. The right lower limb and vulva were swollen, tender and hard with hyperpigmentation and inguinal lymphadenopathy. She had severe anaemia, eosinophilia and negative serology for HIV I and II. Histopathological examination showed a dermal chronic granulomatous infiltrate with fungal hyphae and yeast forms suggestive of Basidiobolus ranarum. There was marked reduction in right leg size and inguinal lymphadenopathy after several weeks of oral itraconazole, and complete healing of ulcers after 10 weeks. The purpose of this report is to increase awareness of this disfiguring condition which is treatable but, if not correctly diagnosed, could result in inappropriate interventions such as amputation and anti-coagulant therapy. FUNDING: None declared.

RESUMO

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.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: The practice of skin lightening has been reported from North America, Europe, Asia, and Africa. In literature, some prevalence rates exceed 50%, and both sexes are involved. Common agents used include hydroquinone, mercury, corticosteroids, and caustic agents. The agents are easily accessible and affordable with very little regulation. Cutaneous and systemic side effects occur but do not appear to be a deterrent, as the notion of light skin as a surrogate for beauty is strong. In Ghana, anecdotal reports of high bleaching rates among certain urban communities resulted in a study supported by the Food and Drugs Authority to determine various facets of this practice. METHODS: A cross-sectional study among adults in selected urban fishing communities of Accra was undertaken. Consecutive cases were enrolled after written informed consent. A questionnaire was administered, followed by physical examination and clinical photographs. Descriptive statistics were used to analyze the data. RESULTS: Of the 555 participants from the three communities, prevalence was 279 (50.3%). Duration of use ranged from 2 months to 17 years. Approximately 212 (76%) used more than one product, and 231 (82%) used agents on their face and body. Dermatological features were hypopigmentation 270 (96.8%), other color changes including ochronosis 241 (86.4%), changes in consistency 141 (50.3%), striae 157 (56.3%), and infections 42 (15.1%). CONCLUSIONS: The prevalence of skin bleaching was 50.3% in these communities, which is high considering the adverse effects from the practice. We recommend regulation of products by enforcing the law, more education, and a population prevalence study.

RESUMO

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.

RESUMO

BACKGROUND: The importance of fevers not due to malaria [non-malaria fevers, NMFs] in children in sub-Saharan Africa is increasingly being recognised. We have investigated the influence of exposure-related factors and placental malaria on the risk of non-malaria fevers among children in Kintampo, an area of Ghana with high malaria transmission. METHODS: Between 2008 and 2011, a cohort of 1855 newborns was enrolled and followed for at least 12 months. Episodes of illness were detected by passive case detection. The primary analysis covered the period from birth up to 12 months of age, with an exploratory analysis of a sub-group of children followed for up to 24 months. RESULTS: The incidence of all episodes of NMF in the first year of life (first and subsequent) was 1.60 per child-year (95 % CI 1.54, 1.66). The incidence of NMF was higher among infants with low birth weight [adjusted hazard ratio (aHR) 1.22 (95 % CI 1.04-1.42) p = 0.012], infants from households of poor socio-economic status [aHR 1.22 (95 % CI 1.02-1.46) p = 0.027] and infants living furthest from a health facility [aHR 1.20 (95 % CI 1.01-1.43) p = 0.037]. The incidence of all episodes of NMF was similar among infants born to mothers with or without placental malaria [aHR 0.97 (0.87, 1.08; p = 0.584)]. CONCLUSION: The incidence of NMF in infancy is high in the study area. The incidence of NMF is associated with low birth weight and poor socioeconomic status but not with placental malaria.

RESUMO

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.

RESUMO

BACKGROUND: Iron supplementation is recommended for pregnant women to meet their iron requirement for a healthy pregnancy. The benefits and risks of universal iron supplementation during pregnancy in malaria endemic countries are currently being debated. As part of a broader study that focused on the effect of heme/HO-1 on pregnancy outcomes in malaria in pregnancy, we determined the association between iron supplementation and free heme levels in blood of pregnant women with and without malaria in Ghana. We hypothesized that pregnant women with malaria who took iron supplements will have higher levels of Heme/HO-1 than those who did not take iron supplements. METHODS: A total of 337 women were recruited for this study. Blood samples were collected for malaria diagnosis and heme/HO-1 measurement. Quantification of heme was done using a heme colorimetric assay kit and HO-1 levels were performed using Enzyme-Linked Immunosorbent Assay (ELISA) on plasma samples. RESULTS: Malaria positive iron supplemented women, in their third trimester, had significantly higher median levels of heme 59.3(43.1 - 60.4) than non-malaria iron supplemented women 35.7(33.0 - 62.2), p = 0.026. Also, malaria positive iron supplemented women had significant higher median levels of HO-16.2(IQR 4.9 - 8.1) than pregnant women who did not take iron supplements 2.9 (IQR 2.1 - 3.8), p = <0.001. CONCLUSION: Although iron supplementation may be highly beneficial and improve pregnancy outcomes for iron deficient or anemic mothers, it is also likely that iron supplementation for pregnant women who are not iron deficient may put this group of women at risk for adverse pregnancy outcomes. Findings from this study sheds light on the effect of iron supplementation on malaria derived heme in pregnancy, which may inform how iron supplementation is recommended for pregnant women who are not iron deficient.

RESUMO

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.

RESUMO

Although the high prevalence of human immunodeficiency virus (HIV), hepatitis B virus (HBV) and syphilis infections among longdistance truck drivers has been well documented globally, such data are sparse from Africa, and there has been no such data from Ghana. This study carried out between the months of January and June 2013 sought to determine the sero-prevalence and risk factors of HIV, HBV and syphilis infections among long distance truck drivers at the Tema sea port, Ghana. Materials and Methods: Of a total of 800 eligible drivers, 106 (13.25%) drivers consented to take part in the study. Subjects voluntarily completed a risk factor questionnaire and provided blood specimen for testing for HIV, syphilis and the surface antigen of HBV (HBsAg). Results: The mean age of the drivers was 40.56 ± 11.56 years. The sero-prevalence of HIV was 0.94%, 14.2% had HBsAg and reactive syphilis serology was 3.8%. On multivariate analysis, the main determinants of HBV infection were; multiple sexual partnership (OR, 6.36; 95% CI: 1.35­29.79), patronage of commercial sex workers (OR, 6.85; 95% CI: 0.88 ­ 52.89), cross-border travelers (OR: 6.89-fold, 95% CI: 0.86 - 55.55) and prolonged duration of trips for more than two weeks (OR: 4.76; 95% CI: 0.59 ­ 38.02). The main determinant of syphilis infection on multivariate analysis was being a Muslim (OR, 2.19; 95% CI: 0.22 ­ 21.74). Conclusion: The data indicate a lower sero-prevalence of HIV but a higher sero-prevalence of syphilis. However, the sero-prevalence of HBV infection is comparable to that of the general population
