RESUMEN

BACKGROUND: Medical tourism is a fast-growing business worldwide with almost every country involved as either a provider and/or consumer. The degree of participation may vary depending on the status of health-care system in that country. This study aims to present our experience in the management of patients who sought urologic care abroad or returned from medical tourism with urologic complications. METHODS: The method of study was based on the documentation of interaction with patients, patients' relations and their agents in a questionnaire between January 2010 and December 2015. The data obtained included, their demographics, indications/motivations for seeking treatment abroad, procedures performed and complications. We also documented the secondary procedures that were performed and complications managed in our center. The data were entered into Microsoft Excel and analysed using descriptive statistics, tables and figures. RESULTS: A total of 113 have either indicated intention of going to seek for urological care abroad or had already had urologic procedures abroad but were attending our clinic for follow up or for management of complications. Only about 12% of these patients were found to have genuine indications for seeking care abroad. Most of the indications were not justifiably based on the current capabilities of our health facility but more due to a lack of trust in the system or at worst pretentious. CONCLUSION: Patients seek for treatment abroad for variable reasons but and most could not be justified based on available local options. India and some Middle-East countries were the favoured destinations, and the quality of care and relative lower cost are the major attractions. The rising trend in medical tourism is fuelled by the poor state of our health-care system, perceived dearth of expertise and a general apathy and lack of trust.

RESUMEN

Retrocaval ureter is a rare anomaly in which the ureter passes behind the inferior vena cava due to abnormal embryogenesis. Very few cases have been reported from Africa. Although the anomaly is congenital, patients become symptomatic in the third or fourth decade of life. We reviewed the records of four patients with the diagnosis of retrocaval ureter and managed in our centre between January 2010 and December 2016. Three patients presented with recurrent colicky right flank pain while one was asymptomatic. Two patients each had Type I and Type II retrocaval ureters, respectively. Surgical repairs were achieved in the three symptomatic cases and recovery was uneventful. Retrocaval ureter, though congenital, manifests in young adults and it may be symptomatic. Pre-operative diagnosis may be difficult when the lesion is high and mimics pelviureteric junction obstruction. Thus, a high index of suspicion is required for pre-operative diagnosis. Under-reporting and asymptomatic cases may account for the low incidence.

RESUMEN

UNLABELLED: Varicella-zoster virus (VZV) is a human herpesvirus, which during primary infection typically causes varicella (chicken pox) and establishes lifelong latency in sensory and autonomic ganglia. Later in life, the virus may reactivate to cause herpes zoster (HZ; also known as shingles). To prevent these diseases, a live-attenuated heterogeneous vaccine preparation, vOka, is used routinely in many countries worldwide. Recent studies of another alphaherpes virus, infectious laryngotracheitis virus, demonstrate that live-attenuated vaccine strains can recombine in vivo, creating virulent progeny. These findings raised concerns about using attenuated herpesvirus vaccines under conditions that favor recombination. To investigate whether VZV may undergo recombination, which is a prerequisite for VZV vaccination to create such conditions, we here analyzed 115 complete VZV genomes. Our results demonstrate that recombination occurs frequently for VZV. It thus seems that VZV is fully capable of recombination if given the opportunity, which may have important implications for continued VZV vaccination. Although no interclade vaccine wild-type recombinant strains were found, intraclade recombinants were frequently detected in clade 2, which harbors the vaccine strains, suggesting that the vaccine strains have already been involved in recombination events, either in vivo or in vitro during passages in cell culture. Finally, previous partial and complete genomic studies have described strains that do not cluster phylogenetically to any of the five established clades. The additional VZV strains sequenced here, in combination with those previously published, have enabled us to formally define a novel sixth VZV clade. IMPORTANCE: Although genetic recombination has been demonstrated to frequently occur for other human alphaherpesviruses, herpes simplex viruses 1 and 2, only a few ancient and isolated recent recombination events have hitherto been demonstrated for VZV. In the present study, we demonstrate that VZV also frequently undergoes genetic recombination, including strains belonging to the clade containing the vOKA strain.

RESUMEN

Background: Elderly patients with benign prostatic hyperplasia are increasingly having minimally invasive surgeries due to their safety. There is also a drive to minimize the duration of postoperative catheterization following transurethral resection of the prostate to reduce hospital stay and encourage early ambulation. These are desirable in the elderly to improve outcomes. Can early catheter removal be done safely in the geriatrics without an increase in presentation to the emergency department with complications? We compare the emergency presentation of elderly patients who had early and delayed catheter removal following transurethral resection of the prostate. Materials and Methods: This was a retrospective review of transurethral resection of the prostate in the elderly (≥70 years) within 2 years in a single hospital. All the patients had monopolar transurethral resection of the prostate and were categorized based on the duration of postoperative catheterization as either early (third postoperative day) or delayed (> third postoperative day). The duration of catheterization was based on surgeon preference. Patients with intraoperative complications were excluded. Data on clinical presentation, comorbidities, and presentation at the emergency department were retrieved and analysed. Results: Forty-one patients were studied with the mean age of patients being 76 ± 4 years. Twenty patients had early catheter removal and 21 had delayed catheter removal. A total of nine patients presented to the emergency department within the 30-day postoperative period with either bleeding urinary retention or incontinence requiring re-catheterization, six had early catheter removal, and three had delayed catheter removal. The catheter duration, preoperative ASA status prostate volume, and preoperative indwelling catheter were not statistically significant determinants of presentation to the emergency department in these elderly men. The presence of comorbidities assessed using the Charlson Comorbidity Index was a statistically significant variable to presentation at the emergency department after surgery P = 0.006. Conclusion: Early catheter removal is safe in elderly patients following transurethral resection of the prostate, however, there is a risk of presentation to the emergency department with complications, especially in patients with comorbidities.

RESUMEN

Background: Bladder spasms due to involuntary contraction of the bladder occur frequently following Transurethral resection of the prostate (TURP). They may be aggravated by the presence of a catheter, blood clots, preoperative overactive bladder, or preoperative ingestion of bladder stimulants like caffeine. These bladder spams are painful, associated with peri-catheter leakage of urine, increased post-operative bleeding, and often refractory to postoperative analgesia. The incidence and risk factors for the occurrence of bladder spasms following TURP need to be reviewed and validated to ensure adequate patient counseling and possible lifestyle modification before surgery. We conducted a prospective review of the determinants of bladder spasms in our patients following TURP. Methodology: The study population was patients with benign prostatic obstruction scheduled for TURP between March 2022 and April 2023. Monopolar transurethral resection of the prostate was done using a continuous flow resectoscope. The primary endpoint of the study was occurrences of bladder spasms postoperatively before the trial without a catheter. Pain perception during the spasms was assessed using a visual analog scale. Clinical data were collected and analyzed to determine their association with the occurrence of bladder spasms postoperatively using regression analysis. Sub-group analysis was also done to correlate significant variables with the severity of pain in patients with spasms. Results: The mean age of the 80 patients reviewed was 66.9 ±8 years. Bladder spasms were seen in 41(51.2%) of the patients. The presence of overactive bladder (OAB) symptoms and the use of bladder stimulants were statistically significant determinants with a p-value of 0.003 and 0.026 respectively. The age of the patient, preoperative indwelling catheter, prostate volume, and resection time were not statistically determinant variables in the occurrence of bladder spasms post-operatively. 61% had severe pains and 39% had mild pains. There was no significant correlation between the presence of OAB or the use of bladder stimulants with the severity of pains in patients with bladder spasms after TURP. Conclusions: Half of the patients are likely to have bladder spasms after TURP. The risk of having these spasms is higher in patients with preoperative OAB or patients who are exposed to bladder stimulants. The severity of spasms is however independent of these risk factors.

RESUMEN

INTRODUCTION: Health-care research in Nigeria has been growing over the years but is constrained by many difficulties. This study aimed to identify the challenges encountered in health-care research and suggest policies to address these problems. MATERIALS AND METHODS: It was a cross-sectional study of medical doctors who have been involved in health-related researches. All participants filled a self-administered online questionnaire comprising 31 questions in five sections. The responses were analyzed using the Google forms and the Statistical Package for the Social Sciences software version 23. RESULTS: The mean age of the study participants was 41.0 ± 8.4 years. Three-quarters of the respondents (75.5%) worked in teaching hospitals. Nearly all (96.6%) carried out their studies using personal funds and only one in 10 had been involved in high-budget projects (≥₦1,000,000). The generation of quality researches was impeded by the restriction of literature review to free online journals (93.2%), incomplete health records (88.0%), limited access to research kits (65.7%), limited use of advanced statistical analysis (29.8%), and challenges with obtaining ethical approval (21.2%). Despite the average online visibility of these researches (52.2%), only 28.5% stated that it has been locally adopted to influence medical practice in their center. CONCLUSION: There is a wide disparity in research capacity among hospital tiers. It is important to leverage on and expand existing partnerships to provide institutional access to premium literature, offer robust, and assessable financial support for the conduct of high-quality researches and provide a framework to bridge the gap in the use of these works to influence practice change in Nigeria.

RESUMEN

BACKGROUND: Traditional clinical examination is perceived to be biased and to overcome this, objective structured clinical examination (OSCE) was introduced. AIMS: The aim was to assess the students' exposure and perception of OSCE as well as its strengths and weaknesses in comparison to conventional clinical examination. SUBJECTS AND METHODS: A cross-sectional study of students who had surgical OSCE was conducted from July 2018 to October 2018 in Ahmadu Bello University, Zaria. Using a structured questionnaire, exposure and perception of OSCE as well its strength and weaknesses in comparison to the conventional clinical examination were assessed with dichotomous questions and a 5-point Likert scale. Data were analyzed with SPSS Version 20. RESULTS: One hundred and thirty-four students responded, mean aged 24.1 ± 4.3 years, with a male-to-female ratio of 2.5:1. Although 64.7% of them strongly agreed that OSCE is the standard mode of examination, only 36.1% strongly agreed that it was easier to pass. More than half of the students perceived that the content of the OSCE was appropriate, wide-scoped, unbiased, and brought out specific areas of weakness. Some students (38.1%), however, felt that there was a need for improvement in the OSCE process, especially in time allocation, but most of them (89.5%) prefer it and agree that it was superior to conventional clinical examination. CONCLUSIONS: The perception of the process and structure of OSCE among the medical students was good. Compared to conventional clinical examination, students found OSCE was easier and fairer, had a better examination of structure and level of coordination, and induced lesser anxiety and fatigue. However, the entire process of OSCE can be improved.

RESUMEN

OBJECTIVES: The objective of this study was to determine the nuances of management, prognostic factors, and outcome of ischemic priapism in patients seen at Ahmadu Bello University Teaching Hospital, Zaria, Nigeria. PATIENTS AND METHODS: We retrospectively studied the case notes of all patients managed for ischemic priapism in the Ahmadu Bello University Teaching Hospital, Zaria, over a period of 10 years (2006-2015). The data extracted included patients' age, occupation, duration of painful penile erection, and previous episodes. Addition information including precipitating factors, hemoglobin genotype, treatment, and complications was also retrieved. Data obtained were analyzed using SPSS version 20. RESULTS: The records of a total of forty patients managed for priapism over the period under review were retrieved. Thirty-three (82.5%) of these patients had an operative intervention. The mean age was 23.7 years with a range of 8-53 years. Sixty percent of patients were young adults in their third decade of life. The minimum duration of erection at presentation was 18 h and a maximum period of 10 days with a mean of 105.5 h (4 days). Thirty-three patients (82.5%) had sickle cell anemia (HbSS). Erectile dysfunction (ED) accounted for 60% of all forms of postpriapism complications. Five patients (12.5%) had residual tumescence from fibrosis, and three patients had recurrence outside the immediate postoperative period. Duration of symptoms before surgical intervention, SSA and previous episodes were the most important prognostic factors. CONCLUSION: Priapism is a disease of the young, mostly sickle cell anemic patients. Late presentation remains the norm in our environment, hence a higher incidence of ED. The distal penile shunt is an effective means of achieving detumescence even with failed conservative management. Favorable outcome is highly dependent on the duration of erection and early intervention.
