The relationship between prevalence and severity of lower urinary tract symptoms (LUTS), and body mass index and mid-abdominal circumference in men in a resource-poor community in Southeast Nigeria: a cross-sectional survey.

BACKGROUND: There is paucity of information on the community-based prevalence and severity of lower urinary tract symptoms (LUTS) in men who are 40 years and older in the southeast region of Nigeria. This study seeks to determine the community-based prevalence of LUTS and the relationship between LUTS, and body mass index (BMI) and mid-abdominal circumference (MAC) in men. METHODS: An interviewer-administered, questionnaire-based survey. Three of nine settlement clusters were randomly selected while systematic random sampling of 1 in 3 eligible subjects was used to select participants. Analysis was done using SPSS® version 20. RESULTS: One thousand three hundred and nineteen duly completed questionnaires were analyzed. The respondents are within ages 40-92 years with mean age 54.2 ± 10.2 years, mean BMI 25.97 ± 4.18Kg/m2 and mean MAC 89.80 ± 12.43 cm. Overall prevalence of LUTS is 20.2%. Nocturia at a prevalence of 19.2% is the most prevalent lower urinary tract symptom and also the earliest to manifest. LUTS prevalence and severity increases with increasing age. About 9.6% report moderate LUTS while 2.3% report severe LUTS. Storage LUTS are reported more frequently than voiding LUTS. LUTS did not vary significantly with BMI, MAC or Wealth-Index. CONCLUSION: LUTS prevalence and severity vary with age, but not with BMI, MAC or Wealth-Index.

Prevalence of, and risk factors for erectile dysfunction in male type 2 diabetic outpatient attendees in Enugu, South East Nigeria.

Context: Erectile dysfunction (ED) is a strong predictor of poor quality of life in men with type 2 Diabetes mellitus (T2DM). Several studies evaluating ED in men with diabetes mellitus have been carried out, but few of these have been done in Nigeria. In Enugu, South East Nigeria, paucity of studies on this subject was observed. Aims: This study aims to determine the prevalence and predictors of ED in men with T2DM attending the diabetes clinics. Settings and Design: A descriptive cross-sectional study of men with T2DM in UNTH and Saint Mary's Hospital, Enugu, was carried out. The systematic sampling method was used to recruit participants. Subjects and Methods: Data collection from participants and their hospital records was done using semi-structured questionnaire. ED was assessed using the 5 items, international index of erectile function questionnaire. Statistical Analysis Used: Data analysis was done using SPSS version 20 and results presented as texts and tables. P value was set at <0.05. Results: A total of 325 participants with mean age of 57.8 ± 13.2 years were involved out of which 94.7% had ED. The proportion of participants with ED had increased with its severity. Predictors of ED included poor glycemic control, longer duration of diabetes, overweight/obesity, and older age. Poor ED health-seeking behavior and treatment were noted. Conclusions: The prevalence of ED is high. Lifestyle interventions targeted at improving glycemic control and weight loss may reduce the burden of this complication. We recommend objective ED screening using standard but brief instruments as part of routine evaluation of men with T2DM.

Informed consent for clinical treatment in low-income setting: evaluating the relationship between satisfying consent and extent of recall of consent information.

BACKGROUND: Treatment informed consent aims to preserve the autonomy of patients in the clinician - patient relationship so as to ensure valid consent. An acceptable method of evaluating understanding of consent information is by assessing the extent of recall by patients of the pieces information believed to have been passed across. When concerns are not satisfactorily addressed from the patients' perspective, recall of consent information may be low. METHODS: This study is a questionnaire - based cross - sectional interview of consecutive adult surgical patients who could give their respective medical histories and who were booked for elective major surgical procedures over a period of 7 months in a tertiary health institution in southeastern Nigeria. Four to five days after a formal consent session, during ward admission, extent of recall of information on the nature of the disease condition or diagnosis, the nature of the planned procedure and the risks involved in the planned procedure were assessed and analyzed on the background of how satisfying the consent sessions were from individual patient's perspective. RESULTS: Generally, the recall of nature of disease condition and nature of planned procedure is better than recall of risks involved in the planned procedure. More specifically however, recall in these 3 domains is significantly better among the patients that affirmed that their concerns were satisfactorily addressed. CONCLUSION: The findings from this study support that no effort should be spared in ensuring that the consent information are satisfying to the patients from the patients' viewpoint.

Prostate Cancer Detected by Screening in a Semi Urban Community in Southeast Nigeria: Correlations and Associations between Anthropometric Measurements and Prostate-specific Antigen.

CONTEXT: Prostate cancer (PCa) is frequently diagnosed at advanced stages in Nigeria. AIMS: To determine the screen detected PCa prevalence in a suburban community and explore any relationships between prostate-specific antigen (PSA) and anthropometric measurements. SETTINGS AND DESIGN: Nsukka is a town and local government area (LGA) in Southeast Nigeria in Enugu State. Towns that share a common border with Nsukka are Edem Ani, Alor-uno, Opi, Orba, and Ede-Oballa. Nsukka LGA has an area of 1810 km2 and a population of 309,633 at the 2006 census. All consecutive responders who met the inclusion criteria were recruited. SUBJECTS AND METHODS: A screening outreach was conducted in one location in Nsukka. PSA testing and digital rectal examinations were performed. Height and weight were measured and body mass index (BMI) was calculated. STATISTICAL ANALYSIS USED: Results were subjected to statistical analysis using SPSS 20 (IBM SPSS Statistics for Windows, Version 20.0. Armonk, NY, USA). Categorical data were analyzed using the Chi-square test, with significance level set at P < 0.05. Pearson's correlation was conducted for interval data (P < 0.05). RESULTS: One-hundred and sixty men met the inclusion criteria and were screened. Age range was 40-81 years; PSA range was 1.20-33.9 ng/ml. Digital rectal examinations (DREs) was abnormal in 17 men. Median BMI was 27.49. A Pearson's correlation coefficient showed a significant correlation between age and PSA, r = 0.127; P ≤ 0.05, and DRE findings and PSA, r = 0.178; P ≤ 0.05. There was no significant correlation between height and PSA, r = -0.99; P = 0.211; weight and PSA, r = -0. 81 P = 0.308; and BMI and PSA, r = -0.066; P = 0.407. 8/21 men consented to prostate biopsy with three positive, giving a screen detected PCa prevalence of 1.875%. CONCLUSIONS: Screen detected PCa prevalence in high this population and efforts to improve early detection may be of value in improving treatment outcomes.

Predicting Gleason score using the initial serum total prostate-specific antigen in Black men with symptomatic prostate adenocarcinoma in Nigeria.

BACKGROUND: Men of Black African descent are known to have the highest incidence of prostate cancer. The disease is also more aggressive in this group possibly due to biologically more aggressive tumor or late presentation. Currently, serum prostate-specific antigen (PSA) assay plays a significant role in making the diagnosis of prostate cancer. However, the obtained value of serum PSA may not directly relate with the Gleason score (GS), a measure of tumor aggression in prostate cancer. This study explores the relationship between serum total PSA at presentation (iPSA) and GS. PATIENTS AND METHODS: The iPSA of patients with histologically confirmed prostate cancer was compared with the obtained GS of the prostate biopsy specimens. The age of the patients at presentation and the prostate volumes were also analyzed with respect to the iPSA and GS. The data were analyzed retrospectively using IBM SPSS Version 20. Pearson correlation was used for numeric variables, whereas Fisher's exact test was used for categorical variables. Significance was set at P≤0.05. RESULTS: There were 205 patients from January 2010 to November 2013 who satisfied the inclusion criteria. iPSA as well as age at presentation and prostate volume were not found to significantly correlate with the primary Gleason grade, the secondary Gleason grade, or the GS. However, the presence of distant metastasis was identified to significantly correlate positively with GS. CONCLUSION: GS may not be confidently predicted by the iPSA. Higher iPSA does not correlate with higher GS and vice versa.

Prostate-specific antigen density values among patients with symptomatic prostatic enlargement in Nigeria.

BACKGROUND: This study aims to estimate the prostate-specific antigen density (PSAD) cutoff level for detecting prostate cancer (CAP) in Nigerian men with "grey zone PSA" (4-10 ng/ml) and normal digital rectal examination findings. We addressed this research question: Is the international PSAD cutoff of 0.15 ideal for detecting CAP in our symptomatic patients with "grey zone PSA?" AIM: To estimate the prostate-specific antigen density (PSAD) cutoff level for detecting CAP in Nigerian men with "grey zone PSA" (4-10 ng/ml) and normal digital rectal examination findings. DESIGN: Prospective. SETTING: A tertiary medical center in Enugu, Nigeria. PARTICIPANTS: Two hundred and fifty-four men with either benign prostatic hyperplasia (BPH) or CAP were recruited. INTERVENTION: Patients with PSA above 4 ng/ml or abnormal digital rectal examination or hypoechoic lesion in the prostate were biopsied. OUTCOME MEASURES: PSAD and histology report of BPH or CAP. RESULTS: Ninety-seven patients had CAP while 157 had benign prostatic hyperplasia (BPH). Seventy-two patients had their serum PSA value within the range of 4.0 and 10 ng/ml. PSAD cutoff level to detect CAP was 0.04 (sensitivity 95.88 %; specificity 28.7 %). CONCLUSIONS: The PSAD cutoff level generated for Nigerian men in this study is 0.04 which is relatively different from international consensus. This PSAD cutoff level has a positive correlation with histology and could detect patients with CAP who have "grey zone PSA."

A cost effective analysis of fixed-dose combination of dutasteride and tamsulosin compared with dutasteride monotherapy for benign prostatic hyperplasia in Nigeria: a middle income perspective; using an interactive Markov model.

BACKGROUND: The number of Nigerian men presenting with benign prostatic hyperplasia is on the rise because of increase awareness about the ailment. With the renewed effort by the national health insurance scheme to cover the informal sector, it becomes imperative to determine the cost implication for managing Benign Prostatic Hyperplasia (BPH) and the cost effective drug combination to be adopted. The objective of this study is to estimate cost effective analysis (CEA) of fixed -dose combination of dutasteride and tamsulosin compared with dutasteride monotherapy from the health service provider perspective design. METHODS: An interactive Markov's model was used to generate incremental cost per QALY and incremental cost per life years gained. 2.9 million Men who were 50 years of age were fed into the model. The outcome measures included: costs of drug treatment, consultation, acute urinary retention (AUR), transurethral resection of prostate (TURP), hospitalisation post TURP, and quality adjusted life years (QALYs), incremental cost per life years gained, and incremental cost per QALY gained. RESULTS: Fixed-dose combination of dutasteride and tamsulosin (FDCT) produced an Incremental cost-effectiveness ratios of US$1481.92 per Quality adjusted for life-years saved. CONCLUSION: Universal FDCT provision for Nigeria has major economic implications. This study in the context of its limitations has demonstrated the cost effectiveness of FDCT for the long term treatment of patients with moderate to severe BPH from the perspective of a developing country. Currently, there are few studies available to give economic data evidence to policy makers in Nigeria which is applicable to developing countries with similar economies. As such, the findings in this study will be relevant to policy makers in these countries.

Payment for Health Care and Perception of the National Health Insurance Scheme in a Rural Area in Southwest Nigeria.

Health insurance coverage of the informal sector is a challenge in Nigeria. This study assessed the methods of payment for health care and awareness about the National Health Insurance Scheme (NHIS) among members of selected households in a rural area in the southwest of Nigeria. Using a multistage sampling technique, a semi-structured, pretested interviewer-administered questionnaire was used to collect data from 345 households. The majority of the people still pay for health care by out-of-pocket (OOP) method. Awareness about the NHIS in Nigeria was poor, but attitude to it was encouraging; and from the responses obtained, the people implied that they were willing to enroll in the scheme if the opportunity is offered. However, lack of trust in government social policies, religious belief, and poverty were some of the factors that might impede the implementation and expansion of the NHIS in the informal sector. Stakeholders should promote socioculturally appropriate awareness program about the NHIS and its benefits. Factors that might present challenges to the scheme should be adequately addressed by the government and other stakeholders associated with prepayment schemes in Nigeria.

Serum total prostate-specific antigen values in men with symptomatic prostate enlargement in Nigeria: role in clinical decision-making.

BACKGROUND: Prostatic enlargement is a common cause of bladder outlet obstruction in men in Nigeria. Malignant enlargements must be differentiated from benign enlargements for adequate treatment of each patient. High serum total prostate-specific antigen (tPSA) levels suggest malignancy, but some of the biopsies done due to a serum tPSA value >4 ng/mL would be negative for malignancy because of the low specificity of tPSA for prostate cancer. This study aims to compare the histologic findings of all prostate specimens obtained from core needle biopsy, open simple prostatectomy, and transurethral resection of the prostate with the respective serum tPSA values in an attempt to decipher the role of serum tPSA in the management of these patients. METHODS: The case notes of patients attended to from April 2009 to March 2012 were analyzed. Essentially, the age of the patient, findings on digital rectal examination, abdominopelvic ultrasonography report on the prostate, serum tPSA, and histology reports from biopsy or prostatectomy specimens as indicated were extracted for analysis. RESULTS: The relationship between age, findings on digital rectal examination, serum tPSA, abdominopelvic ultrasonography report, and histology are compared. A statistically significant relationship existed between a malignant histology and age 65 years and older, suspicious findings on digital rectal examination, suspicious ultrasonography findings, and serum tPSA >10 ng/mL, but not tPSA >4 ng/mL. CONCLUSION: In Nigerian patients with symptomatic prostate enlargement, serum tPSA should be seen as a continuum with increasing risk of prostate malignancy.

Reducing the burden of regular indwelling urinary catheter changes in the catheter clinics: the opinion of patients and relatives on the practice of self-catheterization.

BACKGROUND: Clean intermittent self-catheterization is accepted worldwide as a standard of care for patients with long-standing need for urinary bladder decompression. Evidence of its routine practice in our low-resource setting is lacking, leading to increasing number of patients with a long-standing indwelling urinary catheter. OBJECTIVE: To seek the opinion of patients already using indwelling catheters regarding the practice of self-catheterization. PATIENTS AND METHODS: Over a 4-month period, the opinion of every patient and patient's relative that attended the regular urinary catheter clinic was sought using an intern-administered questionnaire. The data was analyzed using SPSS version 20. RESULTS: A total of 108 patients completed the questionnaire. Age range was 16-100 years with a mean of 62.2±15.5 years. Only 30.5% of the patients had formal education beyond the primary level. The median cost for change of the indwelling catheter was 1,325 naira ($8.28 US) with a range of 500-4,000 naira ($3.13-$25 USD). Analysis showed that: 70.8% of patients aged under 60 years/60.6% of those with formal education beyond primary level/61.9% of those wearing catheters for <3 months would give consent for training in self-catheterization. Higher cost of catheter change did not influence the decision to consider self-catheterization. Of the 59 patient relatives who completed the questionnaire, 63% of those younger than 50 years old and 69.2% of those with tertiary education would be willing to undertake training to administer self-catheterization. CONCLUSION: A select group of patients and accompanying relatives in our low-resource setting are willing to learn and practice self-catheterization.

A case of vulval swelling secondary to female circumcision posing a diagnostic dilemma.

INTRODUCTION: The practice of FGM is most prevalent in the African countries such as Nigeria, Ethiopia, Sudan, Egypt, and some area of the Middle East. It is not restricted to any ethnic, religious or socioeconomic class. There are many reasons for perpetuation of this practice; the most common are cultural and religious beliefs. The aim of this paper is to highlight the diagnostic dilemma associated with this type of case and the psychological trauma of a patient following her unfortunate genital mutilations. PRESENTATION OF CASE: We present the case of epidermal inclusion dermoid cyst in an 18-year-old teenage girl referred to us from the gynecologist as a case of hydrocoele of the canal of Nuck involving the left labia majora. Patient was previously seen by general practitioner who diagnosed a left Bartholins cyst. Excision of the mass, revealed a well encapsulated cystic mass containing serous fluid with no extension to the inguinal area, measured 10cm×8cm. Histology showed epidermoid inclusion dermoid cyst probably related to circumcision (female genital mutilation). DISCUSSION: Implantation dermoid cyst though a recognized complication of FGM is rare in our environment and a high index of suspicion is required any time a girl presents with a vulval swelling. Cosmesis still remains the watchword to assuage the psychological impact on the patient. CONCLUSION: There is need for more public health campaigns to educate communities about the harms of circumcision with the goal of eradicating the practice.
