The effectiveness of ultrasound in the diagnosis of bladder tumours at the Muhimbili National Hospital, Dar es Salaam, Tanzania

The importance of an ultrasound in diagnosis of bladder tumours has been investigated by different authors. Some have questioned its effectiveness while others have considered the technique to be an important tool in the initial evaluation of bladder tumours. This study was carried out to establish the effectiveness of the ultrasound in diagnosis of bladder tumours at the Muhimbili National Hospital in Dar es Salaam, Tanzania. Clinical indications and ultrasound findings were recorded. Cystoscopy was done and findings recorded on a preformed questionnaire. The ultrasound findings were compared to cystoscopy findings and the sensitivity, negativity, positive predictive value and negative predictive value determined. A total of 110 patients were recruited in this study and the male to female ratio was 2:1. The commonest (37%) age group was 41-60 years. The most common clinical indication overall was haematuria in 37% of all cases. In males, bladder outlet obstruction due to stricture was the commonest indication (31%). Out of 110 patients scheduled for cystoscopy, 71 had ultrasound done preoperatively. In these patients 70% had some form of abnormal ultrasound findings. The sensitivity, specificity, positive predictive value, and the negative predictive value (NPV) of ultrasound in detection of bladder tumour were 83%, 93%, 89% and 89%, respectively. In conclusion, ultrasound is an effective method for evaluating patients presenting with haematuria or suspected to have bladder tumours. It is cheap, available, affordable and non-invasive; has a high sensitivity, and therefore it can also be useful in the follow-up of patient with bladder cancer

Post-operative pain prevalence, predictors, management practices and satisfaction among operated cases at a Regional Referral Hospital in Dar es Salaam, Tanzania

Background: Post-operative pain is an essential component of good surgical patient care plan. In developing countries however, the prevalence of post-operative pain is relatively very high and pain control strategies are not very promising. The objective of this study was to assess post-operative pain prevalence, predictors, management practices and satisfaction among operated cases at a regional referral hospital in Dar es Salaam, Tanzania.Methods: Prospective hospital based descriptive observational study of operated cases at a Temeke Regional Referral Hospital in Dar es Salaam, Tanzania. Data was collected using a pre-constructed questionnaire and a visual pain intensity scale.Results: A total of 136 patients were recruited with mean age of 37.1±15 years (range= 14–80 years). The prevalence of pain was 100%, 83.9%, and 36% at 12, 24 and 48 hours, respectively. At 12 hours moderate to worst pain was reported in 95.6% of cases. The main prediction factor for severe to worst pain at 12 hours was orthopaedic procedures (p=0.05, AOR=3.456), while widow/divorced marital status and female sex were negatively correlated to severity of pain (p=0.005, AOR=0.0230 and p=0.000, AOR=0.034, respectively). The commonest drugs prescribed post-operatively were injection pethidine (50.5%) and tramadol (48.9%) and oral tramadol (47.6%). Pain management satisfaction rate was paradoxically high (74.3%), with male sex being the main predictor.Conclusion: The prevalence of early post-operative pain is very high. Male sex and orthopaedic procedures are associated with severe pain. Surgeons therefore need to prioritize analgesic prescription at early hours following operation to minimize pain and suffering to patients focusing on orthopaedic procedures

Emotional and Relationship Dynamics between HIV SeroDiscordance and Concordance Couples: A Narrative Literature Review and Theoretical Framework

Tanzania is among the countries with high prevalence of HIV prevalence in the World. Despite the fact that the epidemic has been, and still is a threat to persons of all ages, recent studies have suggested that most new infections occur among couples in stable relationships. Infected couples are categorised into two: the positive concordant, where both the partners are HIV positive; and sero-discordant couples, where one partner is HIV positive while the other is negative. Recently, researchers and many other stake-holders working on the HIV/AIDS epidemic have given a remarkable attention to this astonishing reality. For instance one study in East and Southern Africa indicates that there are great variations of discordancy varying from 36% to 85%, with an overall rate of 49%. HIV couple sero-discordancy is responsible for varied levels of psychological distress including heightened levels of anxiety, poor emotional adaptation and increased or excessive substance use, most often coupled with exclusion and social isolation within family and in the neighbourhood. However, to date the influence of sero-discordancy on family and couple relationship functioning and how it differs from that among concordant couples remains elusive. Discordancy have been associated with more difficulties as compared to the seroconverted couples, these include relationship and emotional disturbances, sexual contact distancing, marital separation and disruptions. The Lazarus and Folkman’s (1984)\u27s Transactional Model can be helpful in understanding individuals with HIV discordancy on their emotional response, coping strategies and the ultimate decisions towards their marital relationships fate

Characteristics and Outcomes of Patients with Eclampsia and Severe Pre-eclampsia in a Rural Hospital in Western Tanzania: A Retrospective Medical Record Study.

Eclampsia and pre-eclampsia are well-recognized causes of maternal and neonatal mortality in low income countries, but are never studied in a district hospital. In order to get reliable data to facilitate the hospital's obstetric audit a retrospective medical record study was performed in Ndala Hospital, Tanzania. All patients diagnosed with severe pre-eclampsia or eclampsia between July 2011 and December 2012 were included. Medical records were searched immediately following discharge or death. General patient characteristics, medical history, obstetrical history, possible risk factors, information about the current pregnancy, antenatal clinic attendance and prescribed therapy before admission were recorded. Symptoms and complications were noted. Statistical analysis was done with Epi Info®. Of the 3398 women who gave birth in the hospital 26 cases of severe pre-eclampsia and 55 cases of eclampsia were diagnosed (0.8 and 1.6%). Six women with eclampsia died (case fatality rate 11%). Convulsions in patients with eclampsia were classified as antepartum (44%), intrapartum (42%) and postpartum (15%). Magnesium was given in 100% of patients with eclampsia and was effective in controlling convulsions. Intravenous antihypertensive treatment was only started in 5% of patients. Induction of labour was done in 29 patients (78% of women who were not yet in labour). Delivery was spontaneous in 67%, assisted vaginal (ventouse) in 14% and by Caesarean section in 19% of women. Perinatal deaths occurred in 30% of women with eclampsia and 27% of women with severe pre-eclampsia and were associated with low birth weight and prolonged time between admission and birth. 2.4% of women were diagnosed with severe pre-eclampsia or eclampsia. The case fatality rate and overall perinatal mortality were comparable to other reports. Better outcomes could be achieved by better treatment of hypertension and starting induction of labour as soon as possible

Prevalence and predictors of anaemia among patients presenting with kidney diseases at the University of Dodoma Hospital in central Tanzania

Background: Anaemia is a common complication that contributes to the burden of kidney diseases. Anaemia confers significant risk of cardiovascular disease and contributes to decreased quality of life. While the primary cause of anaemia is the inadequate production of erythropoietin by the kidneys to support erythropoiesis, other factors may contribute to anaemia. The aim of this study was to determine the prevalence and predictors of anaemia among patients presenting with kidney diseases at the haemodialysis unit of the University of Dodoma (UDOM) hospital in central Tanzania.Methodology: In this retrospective study we reviewed data of patients who presented at UDOM haemodialysis unit in Tanzania with kidney diseases as from January 2013 to June 2015. Data were descriptively and inferentially analysed using Stata version 11 software.Results: A total of 1,395 patients were involved in this study. Of these, 792 (56.8%) presented with kidney diseases, 249 (31.4%) were found to have anaemia.  The leading cause of anaemia was chronic kidney disease (CKD) 136 (54.6%), blood loss 74(29.7), haemolysis 15 (6.0%), Nutrition 13(5.2%) and others 11 (4.4%). Glomerular filtration rate of < 60 mL/min/1.73 m2 accounted for 59.1% of CKD. Median [IQR] serum creatinine level: 246 [177 – 317] μmol/L, Urea level 16[8 -24] mmol/L and haemoglobin of 9.8 [6.2 - 13.4] g/dL. Prevalence of anaemia was strongly associated with declining glomerular filtration rate (P= 0.01).Conclusion: Anaemia is very common among patients presenting with kidney diseases. These patients require a thorough evaluation to identify and correct causes of anaemia other than erythropoietin deficiency

Morpho-physiological features associated with menopause: recent knowledge and areas for future work

Menopause is the permanent cessation of menstruation resulting from loss of ovarian follicular activity which happens as a result of depletion of primary follicles which is basically an aging effect. Depletion of ovarian follicles is reflected as declined production of oestradiol which is currently known to be central to the morphologic and physiological changes that happen during the climacteric, menopause and post menopause periods. The cessation of oestradiol production is much more pronounced in tissues with oestrogen receptors such as bones, brain, blood vessels, central nervous system and the skin. But generally little is known on the subject and in particular the bioactive substances involved in the process such that there are some symptoms that menopause women experience which not only defy clinicians but also challenge the management of the condition. This article is presented to shade light to what is currently known, what is not known and stimulate future research which may reveal more understanding and advance our knowledge on management of women throughout the climacteric and menopausal periods

The male circumcision: the oldest ancient procedure, its past, present and future roles.

Circumcision, a surgical removal of male prepuce has existed throughout human history, and it appears it shall exist until humanity ends. During its entire existence, there have been changing reasons or indications from cultural, traditional, religious and currently medical, and it has vehemently been criticized by some individuals for different reasons and in different countries. Emergency of new diseases particularly Human Immunodeficient virus (HIV) has brought the ancient procedure back on spot light, this has come as a result of recent studies which have demonstrated that it does not only reduces significantly the rate of HIV infection, as well as penile cancer and cervical cancer. This has lead to massive male circumcision campaigns in areas with low prevalence of circumcision. On the other hand the socio-cultural and sexual aspects of male circumcision have been studied but often ignored. This article will therefore increase awareness of male circumcision and the increasing roles with time, recommend up scaling of medical male circumcision and possible safe circumcision training to tradition circumcisers
