Abstract: Background: Some evidence has shown that the prevalence of hypoactive sexual desire and erectile dysfunction (ED) is associated with testosterone levels whilst higher levels of testosterone have been reported to increase the frequency of intercourse. Available evidence points towards an etiologic role for hypogonadism in the causation of diabetes, metabolic syndrome (Mets) and sexual dysfunction (SD) even though the exact pathophysiological linkage is yet to be fully elucidated. This study therefore sought to evaluate the impact of testosterone as well as its bioactive components on both the MetS and SD. Method: Diabetic men engaged in a stable heterosexual relationship for at least 2 years were recruited for this study. Participants were at least 18 years and provided an informed and signed consent to partake in this study. Fasting blood samples were taken from the participants for biochemical and hormonal assay. The participants were then evaluated using the Golombok Rust Inventory of Sexual Satisfaction for males (GRISS-M). Metabolic syndrome was assessed using the NCEP-ATP III, IDF and WHO criteria. All data analyses were performed using the SPSS software, version 11.0 systat, Inc. Germany and GraphPad Prism, version 5.0, San Diego California, USA. Results: The mean total, free and bioavailable testosterone as well as SHBG recorded among the participants was 7.10 ± 1.23 ng/ml, 0.10 ± 0.01 ng/ml, 7.01 ± 1.41 ng/ml and 4.33 ± 1.12 nmol/l respectively. Subjects with the MetS showed significantly lower SHBG levels in comparison with subjects without the MetS. Participants with raised triglyceride levels showed significantly lower levels of total, free and bioavailable testosterone when compared to participant without raised triglycerides. Participants with problems of avoidance and infrequency of sexual activity showed significantly lower levels of total, free and bioavailable testosterone when compared to participants without avoidance or infrequency problems. The +SD/+MetS group recorded the lowest SHBG levels. Conclusion: Testosterone and its bioactive components are associated with male libido as well as the metabolic syndrome. Low levels of free and bioavailable testosterone are true determinants of the MetS in men.

Abstract: Sexual functioning was determined in 300 consecutive diabetic men (age range: 18-82 years) visiting the diabetic clinic of Tema General Hospital with the Golombok Rust Inventory of Sexual Satisfaction (GRISS) questionnaire, between November, 2010 and March, 2011. In addition to the socio-demographic characteristics of the participants, the level of glycosylated haemoglobin, fasting blood sugar (FBS) and serum testosterone were assessed. All the men had a steady heterosexual relationship for at least 2 years before enrolment in the study.Out the 300 participants contacted, the response rate was 91.3% after 20 declined participation and 6 incomplete data were excluded All the respondents had at least basic education, 97.4% were married, 65.3% were known hypertensive, 3.3% smoked cigarettes, 27% took alcoholic beverages and 32.8% did some form of exercise. The 69.3% SD rate observed in this study appears to be related to infrequency (79.2%), non-sensuality (74.5%), dissatisfaction with sexual acts (71.9%), non-communication (70.8%) and impotence (67.9%). Other areas of sexual function, including premature ejaculation (56.6%) and avoidance (42.7%) were also substantially affected. However, severe SD was seen in only 4.7% of the studied population. The perceived "adequate", "desirable", "too short" and "too long intra-vaginal ejaculatory latency time (IELT) are 5-10, 5-10, 1-2 and 15-30 minutes respectively. Testosterone correlates negatively with glycated haemoglobin (HBA1c), FBS, perceived desirable, too short IELT, and weight as well as waist circumference.SD rate from this study is high but similar to that reported among self-reported diabetic patients in Kumasi, Ghana and vary according to the condition and age. The determinants of SD from this study are income level, exercise, obesity, higher perception of "desirable" and "too short" IELT.Some of the consequences of diabetes include various medical [1], psychological [2], and sexual [3] dysfunctions.

Abstract: The study participants consisted of married couples between the ages of 19 and 66 living in the province of Kumasi, Ghana. Socio-demographic information and Golombok-Rust Inventory of Sexual Satisfaction (GRISS) questionnaires were administered to 200 couples who consented to take part in the study. All 28 questions of the GRISS are answered on a five-point (Likert type) scale from "always", through "usually', "sometimes", and "hardly ever", to "never". Responses are summed up to give a total raw score ranging from 28-140. The total score and subscale scores are transformed using a standard nine point scale, with high scores indicating greater problems. Scores of five or more are considered to indicate SD. The study was conducted between July and September 2010.Out of a total of 200 married couples, 179 completed their questionnaires resulting in a response rate of 89.5%. The mean age of the participating couples as well as the mean duration of marriage was 34.8 ± 8.6 years and 7.8 ± 7.6 years respectively. The husbands (37.1 ± 8.6) were significantly older (p < 0.0001) than their corresponding wives (32.5 ± 7.9). After adjusting for age, 13-18 years of marriage life poses about 10 times significant risk of developing SD compared to 1-6 years of married life among the wives (OR: 10.8; CI: 1.1 - 49.1; p = 0.04). The total scores (6.0) as well as the percentage above the cut-off (59.2) obtained by the husbands compared to the total score (6.2) and the percentage above cut-off (61.5) obtained by the wives, indicates the likely presence of sexual dysfunction. The prevalence of impotence and premature ejaculation were 60.9% and 65.4% respectively from this study and the prevalence of vaginismus and anorgasmia were 69.3% and 74.9% respectively. The highest prevalence of SD subscales among the men was dissatisfaction with sexual act followed by infrequency, whereas the highest among the women was infrequency followed by anorgasmia. Dissatisfaction with sexual intercourse a

Abstract: The Golombok Rust Inventory of Sexual Satisfaction (GRISS) was administered to 150 Ghanaian men with various medical conditions between 19 and 66 years old (mean ± standard deviation: 40.01 ± 12.32 years) domiciled in the Kumasi metropolis.Out of the total 150 questionnaires administered, 105 (70.0%) men returned the questionnaires. Questionnaires from 3 men were incomplete, leaving 102 complete and evaluable questionnaires, indicating a 68.0% response rate. Of the remaining 102 men, 88.2% were married, 70.6% had attained higher education, 88.2% were non-smokers. Whereas 54.9% were engaged in exercise, 61.8% indulged in alcoholic beverages. The prevalence of the various medical conditions include: diabetes (18%), hypertension (24.5%), migraine (11.8%), ulcer (7.8%), surgery (6.9%), STD (3.9) and others (26.5%). The prevalence of SD among the respondents in the study was 59.8%. The highest prevalence of SD was seen among ulcer patients (100%), followed by patients who have undergone surgery (75%), diabetes (70%), hypertension (50%), STD (50%) and the lowest was seen among migraine patients (41.7%).SD rate is high among Ghanaian men with medical conditions (about 60%) and vary according to the condition and age.Sexual dysfunction (SD) is an important public health problem that compromises the overall quality of life of the patients and their sexual partners [1,2]. This consequently leads to loss of emotional and physical intimacy and at times leads to divorce. Customarily, male SD has been attributed to psychogenic factors, however, advances in pathophysiology research indicate vascular malfunction in the majority of patients. The vascular malfunction could be as a result of atherosclerotic lesions in the penile arteries that consequently lead to diminished blood flow.About 322 million men worldwide are projected to develop erectile dysfunction (ED) by the year 2025 with the largest projection increases in the developing world that is Africa, Asia, and South America.
Alcohol Consumption Is Associated with Hypogonadism and Decreased Sexual Function in Ghanaian Diabetics  [PDF]

Advances in Sexual Medicine (ASM) , 2017, DOI: 10.4236/asm.2017.73009
Abstract: Introduction: Alcohol usage has largely been seen as a risk factor for the development of sexual dysfunction as well as erectile dysfunction. Others have reported that prolonged alcohol usage and abuse is compatible with normal sexual function in the absence of endocrinological problems as well as hepatic dysfunction. About seventy five (75) percent of alcoholics have various sexual difficulties with improvements in sexual functions occurring after treatment of alcoholism and psychosexual therapy. It is evident from the various reports over the years that mild and occasional alcohol usage is not as much implicated in the causation of SD and its other forms as heavy, addictive or dependent alcohol usage. Alcohol usage has also long been linked to hypogonadism, testicular atrophy as well as leydig cell toxicity. Alcohol induced hypogonadism has been reported to resolve after withdrawal of alcohol use. Since both diabetes and alcohol usage have been strongly associated with both hypogonadism and sexual dysfunction, it is logical to expect that diabetics who frequently consume alcohol will have a worsened hypogonadal state and sexual function. This research therefore seeks to provide evidence of an association between alcohol consumption in diabetics and a worsened sexual dysfunction in comparison to diabetics who did not consume alcohol. Methods: Type II diabetic patients attending the Diabetic Clinic at the Maamobi General Hospital between the periods of January 2010 and March 2011 were consecutively recruited for this study. Diabetics with other known endocrinological diseases and physical disabilities were excluded from the study. Sexual function was assessed using the GRISS-M. Early morning fasting samples were used in lipid and testosterone profile assays. Results: Study participants who consumed alcohol recorded higher levels of triglycerides and LDL-Cholesterol. They also recorded significantly lower levels of bioavailable testosterone. Furthermore they also recorded higher scores for impotence, premature ejaculation, non-sensuality and infrequency but lower scores for avoidance and were about six times more likely to be infrequent in their sexual activity in comparison with those who did not consume alcohol. Conclusion: Alcohol consumption among diabetic males is associated with hypogonadism and has an impact on several domains of male sexual function. Diabetic males should be advised to avoid alcohol abuse in order to facilitate the management of diabetes associated sexual

Abstract: Purpose: We describe the commonest pathology responsible for lower urinary tract obstruction (LUTO) and associated symptoms such as UTI, etc. among males at the Komfo Anokye Teaching Hospital (KATH) in Kumasi. Materials and Methods: Between January and December 2009, prospective cross sectional hospital based study was conducted involving 103 subjects. Patients with symptoms of LUTO and who were on short admission (up to 48 hours) at the accident and emergency unit of KATH were identified as potential study subjects. All the patients presented with acute retention of urine at the emergency unit of KATH and urethral catheterization was attempted to relieve them of the retention under sterile conditions. Those patients whose initial catheterization failed went through suprapubic cystostomy (suprapubic catheterization). Urine specimens for culture and sensitivity tests were then collected into sterile urine containers immediately after the catheterization (irrespective of type). Ultrasound Scan was requested for all the patients to assist in diagnosing enlargement of the prostate and other associated urological pathologies. Retrograde urethrogram was however, requested for those patients with suprapubic catheterization and which helped in the diagnosis of the urethral stricture. For a particular child, urethral catheter was passed under sterile condition and Micturicting Cysto-Urethrogram (MCUG) was done to assist in diagnosing posterior urethral valve and other conditions. Those subjects whose urinalysis revealed pyuria and positive urine culture and who had voluntarily agreed to enter the study were enrolled. Subjects whose urine culture had multiple bacteria growth that was deemed to be contaminants were excluded from the study. Results: The mean age for males with LUTO was 62 years. The youngest male with LUTO was aged 2 years whilst the maximum age was 93 years. LUTO due to prostatic hyperplasia was found in 79 (76.7%) men; 23 (22.3%) had LUTO due to urethral stricture and 1 (1.0%) (youngest male). The mean age of patients that had LUTO due to urethral stricture was approximately 39 years. The youngest patient with LUTO due to urethral stricture aged 22 years whilst the maximum age was 72 years. Microbiological results indicated that Escherichia coli caused 53 (51.5%) of urinary tract infection (UTI) due to LUTO; Klebsiella = 23 (22.3%); Staphylococcus aureus = 14 (14.6%); Pseudomonas spp. = 8 (7.8%) Proteus = 2 (2.0%); Citrobacter = 1 (1.0%) and Salmonella spp. =1 (1.0%). Conclusion: The most common

International Journal of Pharmacology , 2009,
Abstract: The anti-nociceptive effect of an ethanolic leaf extract of Palisota hirsuta, a plant used locally in Ghana for various painful conditions was assessed, using various pain models. Palisota hirsuta extract (PHE) together with morphine and diclofenac (positive controls), all showed significant dose-dependent anti-nociceptive activity in all the models used, that is the tail withdrawal test, the inflammatory-induced mechanical hyperalgesia test, the acetic acid induced writhing test and the formalin test. The anti-nociceptive effect exhibited by PHE in the formalin test was reversed by the systemic administration of the non-selective opioid antagonist, naloxone, the NO synthase inhibitor, Nω-nitro-arginine methyl ester (L-NAME) and the ATP-sensitive K+ channel inhibitor, glibenclamide. However, theophyline, a non-selective adenosine receptor antagonist did not reverse this effect. PHE, unlike morphine, did not induce tolerance to its anti-nociceptive effect in the formalin test after chronic administration and also morphine tolerance did not cross-generalize to PHE. Overall, the present results demonstrate that the anti-nociceptive effects of PHE might partially or wholly be due to the stimulation of peripheral opioid receptors through the activation of the nitric oxide-cyclic GMP-ATP-sensitive K+ (NO/cGMP/K+ATP)-channel pathway without tolerance induction after chronic administration.

Journal of Science and Technology (Ghana) , 2006,
Abstract: Secamone afzelii has been used traditionally for wound healing. To confirm the fokloric uses of the plant, the methanol extract of the plant was tested for antimicrobial and antioxidant activities, since antimicrobial agents and antioxidants facilitate wound healing. The extract showed some level of antimicrobial and antioxidant activities. The selective antimicrobial and significant antioxidant activities suggest that the folkloric use of the plant as a wound healing may be based on the antimicrobial and antioxidant roles.

Ghana Medical Journal , 2007,
Abstract: Background: Malignant neoplasms are set to become a leading cause of childhood death in sub- Saharan Africa as immunization programmes reduce deaths due to infectious diseases. Knowledge of the pattern of deaths from these neoplasms is therefore desirable. Objective: To describe the pattern of deaths from paediatric malignancies, compare this to morbidity figures and provide baseline data for planning child care services. Methods: A 10 year retrospective survey of autopsy cases of paediatric malignancies at the Korle-Bu Teaching Hospital Mortuary was carried out based on autopsy files form January 1, 1990 to December 31, 1999 Results: A total of 252 cases of childhood malignant tumours were retrieved, 139 males and 113 females with a male to female ratio of 1.2:1. The most common malignancy was lymphoma forming 54% of cases and almost all of Non-Hodgkin’s type. Non-Burkitts type (29%) was the commonest followed by Burkitts (24%) and Hodgkin’s disease only one percent. The lymphomas were followed by central nervous system (CNS) tumours (13%), nephroblastomas(10.3%) leukemias (6.7%) hepatic tumours (4%) and sarcomas (2.6%). Less common tumours were Neuroblastomas (2.4%) and retinoblastomas (2%). Conclusion: Overall the pattern of deaths from paediatric malignancies followed the pattern of relative incidence in morbidity figures from Ghana and the subregion except for a relatively higher proportion of deaths from CNS tumours and a lower proportion from sarcomas. The pattern of cancer deaths seen in this study is similar to that seen in advanced countries except that lymphomas replace leukemia as the commonest cause of death

Abstract: 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-1β, 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-γ, TNF-α, IP-10, MCP-1 (MCAF), MIP-1α, MIP-1β, RANTES, SDF-1α, CXCL11 (I-TAC), Fas-ligand [Fas-L], soluble Fas [sFas], sTNF-R1 (p55), sTNF-R2 (p75), MMP-9, TGF-β1, PDGF bb and VEGF) were measured and the results compared between the 3 groups.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-1β, 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.The parasite-induced local cerebral dysregulation in the production of IP-10, 1L-8, MIP-1β, 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.Malaria is an important neglected disease and one of the most important global health problems, potentially affecting more than one third of the world's population. Cerebral malaria (CM) is a deadly complication of Plasmodium falciparum infection, associated with a 10–14% mortality rate and approximately 1–2 million annual deaths among young children predominantly in sub-Saharan Africa and Southeast Asia, yet its pathogenesis remains incompletely understood. In Ghana, malaria has a wide spectrum of presentations: from asymptomatic carriers to mild malaria to multifactorial severe disease, including CM and severe malarial anemia (SMA) [1-5].CM
