RESUMEN

Astronauts and cancer patients are subject to similar multisystem physiological toxicities. Over the past sixty years, NASA developed a state-of-the-art countermeasures program (CMP) to characterize and mitigate the physiological consequences of spaceflight. Here, we propose a NASA-modeled CMP to elucidate and abrogate physiological toxicities in patients with cancer.

RESUMEN

Forest management practices play multifaceted roles in enhancing the geophysical properties that affect raindrop erosion in the watershed, and consequently, sediment deposition in the reservoir. The current work attempts to integrate empirical and physically-based modeling approaches to quantify the impacts of forest conservation on erosion risk and potential sediment accumulation in the mixed-forested Ogouchi Dam watershed in Japan. The reliability of the empirical model for estimating the total erodibility coefficient (TEr), as a function of various forest properties, was evaluated by applying the mathematical expression to multiple forest conditions and comparing the values to field-measured soil erosion rates. The spatial distribution of the empirically derived values showed that about 25.8% of the Government-managed forests and 45.1% of the private forests have higher risks of raindrop splash erosion compared to natural forests. The TEr value in each small Government-divided forest land (less than 5 ha) was then corresponded to the MUSLE management practice factor (MUSLE P) input in each hydrologic response unit (HRU) in the Soil and Water Assessment Tool (SWAT) model to create a sediment yield distribution map and to predict the amounts of sediment accumulation for different management scenarios. The spatial distribution of sediment yield for the base condition showed that 20.9% of the Government-managed forests and 61.6% of the private forests have higher probable amounts of sediment yield relative to the value simulated in the natural forest. A maximum cumulative sediment reduction of about 14.4% is likely attainable upon the complete control of the Government in the entire planted forest area. Overall, this study effectively utilized the field survey datasets to develop a robust empirical model for quantifying erosion risk and was able to couple the results to a GIS-based model that predicts the amounts of sediment yield under varying environmental conditions.

RESUMEN

Urban forests are being threatened by rapid urbanization, biodiversity crises, and climate variability. In response, governments are increasingly collaborating with the public for solutions to these mounting challenges. Non-governmental organizations (NGOs) are dominant players in these collaborations because of their ability to supplement governments' expertize and resources and bring social and ecological issues to the forefront of civic agendas. Despite their growing visibility in urban forest management, there is a lack of attention directed to the forms and range of NGO relationships. This study focuses on addressing this gap and examining collaborations between local governments and NGOs in urban forest programming by characterizing their components including mandates, relationship ties, accountability, resource exchange, and power dynamics. We collected data using semi-structured interviews with three groups: leaders of NGOs, municipal government officials in an urban forest or public works departments, and urban-forest experts who have observed their interactions. The participants represent 32 individuals in nine Canadian cities. Our results indicate that NGO-government collaborations have relational ties and accountability processes that are both formal and informal in nature. Formality in collaborations is often associated with the amount of funding, proximity to government, or size of the NGO. In addition, our findings suggest that NGOs present an opportunity for local governments to supplement their resources and capacity. While the strength and formality of collaborations may be a product of NGO size and budgets, public servants should not hesitate to engage smaller, grassroots NGOs to realize their public service mandates. Characterizing the components of these governance processes provides a benchmark for practitioners participating in similar public-civic interactions and arms them with the knowledge to navigate collaborative decision-making.

RESUMEN

BACKGROUND: HIV status disclosure facilitates access to HIV-related prevention and treatment services and increases opportunities for social support, HIV risk reduction with partners, and index testing for sexual partners or children. This study assessed the effect of a program model of community-based social welfare volunteers on HIV status disclosure among caregivers of orphans and vulnerable children (OVC). METHODS: This was a longitudinal study, which was based on OVC caregivers who were beneficiaries of the USAID Kizazi Kipya project in Tanzania. They were enrolled (baseline) by community social welfare volunteers during 2017-2018, received services, and reassessed at midline in 2019. Caregivers who reported having been HIV tested, were asked to voluntarily report the status in order for the volunteers to establish and provide needed services. Those who reported their HIV status as negative or positive were grouped as "disclosed", and those who knew their status but did not report it were documented as "undisclosed". McNemar's tests compared disclosure rates at baseline and midline. Multivariable analysis was conducted using generalized estimating equation (GEE). RESULTS: The study analyzed 140,664 caregivers (72% female) from 81 district councils of Tanzania. Their mean age at enrollment was 47.4 years. Overall, 81.3% of the caregivers disclosed their HIV status to the project staff at baseline; this increased significantly to 96.1% at midline (p < 0.001). Disclosure at baseline varied significantly by sociodemographic characteristic (p < 0.05), with higher disclosure in females, among urban residents, and higher educated caregivers. However, the observed disclosure variations by sociodemographic characteristics at baseline disappeared at midline and disclosure reached around 96% across the characteristics (p > 0.05). In the multivariable analysis, caregivers' likelihood of HIV status disclosure was nearly 6 times higher at midline than at baseline, when baseline characteristics were adjusted for (OR = 5.76, 95% CI 5.59-5.94, p < 0.001). There were 26,329 caregivers who did not disclose their HIV status at baseline (i.e., 0% diclosure rate at baseline), but 94.7% (n = 24,933) had disclosed by midline, and their disclosure trend was rapidly increasing as their duration of exposure to the project increased. CONCLUSIONS: This study detected an increased caregivers' HIV status disclosure to the USAID Kizazi Kipya project staff by 14.8%, from 81.3% at baseline to 96.1% at midline within an average project exposure period of 1.4 years. The observed loss of sociodemographic differences in HIV status disclosure rate at midline implies that community-based interventions may be well-positioned to successfully address and eliminate sociodemographic barriers to service uptake and consequently improve services coverage and health outcomes.

RESUMEN

BACKGROUND: HIV status disclosure facilitates receipt of HIV prevention and treatment services. Although disclosure to sexual partners, family members or friends has been extensively studied, disclosure to community-based HIV programs is missing. This study assesses the magnitude of, and factors associated with undisclosed HIV status to a community-based HIV prevention program among caregivers of orphans and vulnerable children (OVC) in Tanzania. METHODS: Data are from the USAID-funded Kizazi Kipya project that seeks to increase uptake of HIV, health, and social services by OVC and their caregivers in Tanzania. Data on OVC caregivers who were enrolled in the project during January-March 2017 in 18 regions of Tanzania were analyzed. Caregivers included were those who had complete information on their HIV status disclosure, household socioeconomic status, and sociodemographic characteristics. HIV status was self-reported, with undisclosed status representing all those who knew their HIV status but did not disclose it. Multilevel mixed-effects logistic regression, with caregivers' HIV status disclosure being the outcome variable was conducted. RESULTS: The analysis was based on 59,683 OVC caregivers (mean age = 50.4 years), 71.2% of whom were female. Of these, 37.2% did not disclose their HIV status to the USAID Kizazi Kipya program at the time of enrollment. Multivariate analysis showed that the likelihood of HIV status non-disclosure was significantly higher among: male caregivers (odds ratio (OR) = 1.22, 95% confidence interval (CI) 1.16-1.28); unmarried (OR = 1.12, 95% CI 1.03-1.23); widowed (OR = 1.12, 95% CI 1.07-1.18); those without health insurance (OR = 1.36, 95% CI 1.28-1.45); age 61 + years (OR = 1.72, 95% CI 1.59-1.88); those with physical or mental disability (OR = 1.14, 95% CI 1.04-1.25); and rural residents (OR = 1.58, 95% CI 1.34-1.86). HIV status non-disclosure was less likely with higher education (p < 0.001); and with better economic status (p < 0.001). CONCLUSION: While improved education, economic strengthening support and expanding health insurance coverage appear to improve HIV status disclosure, greater attention may be required for men, unmarried, widowed, rural residents, and the elderly populations for their higher likelihood to conceal HIV status. This is a clear missed opportunity for timely care and treatment services for those that may be HIV positive. Further support is needed to support disclosure in this population.

RESUMEN

BACKGROUND: Utilization of antiretroviral therapy (ART) is crucial for better health outcomes among people living with the human immunodeficiency virus (PLHIV). Nearly 30% of the 1.6 million PLHIV in Tanzania are not on treatment. Since HIV positive status is the only eligibility criterion for ART use, it is critical to understand the obstacles to ART access and uptake to reach universal coverage of ART among PLHIV. For the caregivers of orphans and vulnerable children (OVC) LHIV and not on ART, attempts to identify them and ensure that they initiate and continue using ART is critical for their wellbeing and their ability to care for their children. METHODS: Data are from the community-based, United States Agency for International Development (USAID)-funded Kizazi Kipya project that aims at scaling up the uptake of HIV/AIDS and other health and social services by orphans and vulnerable children (OVC) and their caregivers. HIV positive caregivers of OVC who were enrolled in the USAID Kizazi Kipya project between January 2017 and June 2018 were included in this cross-sectional study. The caregivers were drawn from 11 regions: Arusha, Iringa, Katavi, Kigoma, Mara, Mbeya, Morogoro, Ruvuma, Simiyu, Singida, and Tanga. The outcome variable was ART status (either using or not), which was enquired of each OVC caregiver LHIV at enrollment. Data analysis involved multivariable analysis using random-effects logistic regression to identify correlates of ART use. RESULTS: In total, 74,999 caregivers living with HIV with mean age of 44.4 years were analyzed. Of these, 96.4% were currently on ART at enrollment. In the multivariable analysis, ART use was 30% lower in urban than in rural areas (adjusted odds ratio (OR) = 0.70, 95% confidence interval (CI) 0.61-0.81). Food security improved the odds of being on ART (OR = 1.29, 95% CI 1.15-1.45). Disabled caregivers were 42% less likely than non-disabled ones to be on ART (OR = 0.58, 95% CI 0.45-0.76). Male caregivers with health insurance were 43% more likely than uninsured male caregivers to be on ART (OR = 1.43, 95% CI 1.11-1.83). Caregivers aged 40-49 years had 18% higher likelihood of being on ART than the youngest ones. Primary education level was associated with 26% increased odds of being on ART than no education (OR = 1.26, 95% CI 1.13-1.41). CONCLUSIONS: Although nearly all the caregivers LHIV in the current study were on ART (96.4%), more efforts are needed to achieve universal coverage. The unreached segments of the population LHIV, even if small, may lead to worse health outcomes, and also spur further spread of the HIV epidemic due to unachieved viral suppression. Targeting caregivers in urban areas, food insecure households, who are uninsured, and those with mental or physical disability can improve ART coverage among caregivers LHIV.

RESUMEN

BACKGROUND: Tanzania has met only 50.1% of the 90% target for diagnosing HIV in children. The country's pediatric case finding strategy uses global best practices of index testing, provider-initiated counselling and testing, and targeted community testing of at-risk populations to find about 50,000 children living with HIV (CLHIV) who are undiagnosed. However, context-specific strategies are necessary to find the hidden children to meet the full 90% target. This study assesses whether sex of the caregiver is associated with HIV status of orphans and vulnerable children (OVC) as a valuable strategy for enhanced pediatric case findings. METHODS: Data originate from the community-based, United States Agency for International Development (USAID)-funded Kizazi Kipya Project, which works towards increasing OVC's and their caregivers' uptake of HIV/AIDS and other health and social services in Tanzania. Included in this study are 39,578 OVC ages 0-19 years who the project enrolled during January through March 2017 in 18 regions of Tanzania and who voluntarily reported their HIV status. Data analysis involved multi-level logistic regression, with OVC HIV status as the outcome of interest and caregiver's sex as the main independent variable. RESULTS: Three-quarters (74.3%) of the OVC included in the study had female caregivers, and their overall HIV prevalence was 7.1%. The prevalence was significantly higher (p < 0.001) among OVC with male caregivers (7.8%) than among OVC with female caregivers (6.8%), and indeed, multivariate analysis showed that OVC with male caregivers were significantly 40% more likely to be HIV-positive than those with female caregivers (OR = 1.40, 95% CI 1.08-1.83). This effect was the strongest among 0-4 year-olds (OR = 4.02, 95% CI 1.61-10.03), declined to 1.72 among 5-9 year-olds (OR = 1.72, 95% CI 1.02-2.93), and lost significance for children over age 9 years. Other significant factors included OVC age and nutritional status; caregiver HIV status and marital status; household health insurance status, and family size; and rural versus urban residence. CONCLUSIONS: OVC in Tanzania with male caregivers have a 40% higher likelihood of being HIV-positive than those with female caregivers. HIV risk assessment activities should target OVC with male caregivers, as well as OVC who have malnutrition, HIV-positive caregivers, or caregivers who do not disclose their HIV status to community volunteers. Further, younger HIV-positive OVC are more likely to live in rural areas, while older HIV-positive OVC are more likely to live in urban areas. These factors should be integrated in HIV risk assessment algorithms to enhance HIV testing yields and pediatric case-finding in the OVC population in Tanzania.

RESUMEN

BACKGROUND: Tanzania has a maternal mortality ratio of 556 per 100,000 live births, representing 21% of all deaths of women of reproductive age. Hemorrhage, mostly postpartum hemorrhage (PPH), is estimated to cause at least 25% of maternal deaths in Tanzania. In 2008, the Ministry of Health, Community Development, Gender, Elderly and Children launched interventions to improve efforts to prevent PPH. Competency-based training for skilled birth attendants and ongoing quality improvement prioritized the practice of active management of the third stage of labor (AMTSL). METHODS: A cross-sectional study was conducted in 52 health facilities in Tanzania utilizing direct observations of women during labor and delivery. Observations were conducted in 2010 and, after competency-based training and quality improvement interventions in the facilities, in 2012. A total of 489 deliveries were observed in 2010 and 558 in 2012. Steps for AMTSL were assessed using a standardized structured observation checklist that was based on World Health Organization guidelines. RESULTS: The proportion of deliveries receiving all three AMTSL steps improved significantly by 19 percentage points (p < 0.001) following the intervention, with the most dramatic increase occurring in health centers and dispensaries (47.2 percentage point change) compared to hospitals (5.2 percentage point change). Use of oxytocin for PPH prevention rose by 37.1 percentage points in health centers and dispensaries but remained largely the same in hospitals, where the baseline was higher. There was substantial improvement in the timely provision of uterotonics (within 3 min of birth) across all facilities (p = 0.003). Availability of oxytocin, which was lower in health centers and dispensaries than hospitals at baseline, rose from 73 to 94% of all facilities. CONCLUSION: The quality of PPH prevention increased substantially in facilities that implemented competency-based training and quality improvement interventions, with the most dramatic improvement seen at lower-level facilities. As Tanzania continues with efforts to increase facility births, it is imperative that the quality of care also be improved by promoting use of up-to-date guidelines and ensuring regular training and mentoring for health care providers so that they adhere to the guidelines for care of women during labor. These measures can reduce maternal and newborn mortality.

RESUMEN

BACKGROUND: Recipients of healthcare services have rights, which must be acknowledged and protected. Such rights include observance of acceptable patient physical, mental, spiritual, and social needs guided by commonly accepted rules and regulations. The objective of this study was to conduct a systematic review and meta-analysis of awareness rates and observance of patient rights in Iran from the perspective of the patient. METHODS: In this study, various references such as Medline (PubMed), Scopus, Scientific Information Database (SID), Google scholar, Magiran, and IranMedex were searched (from August to December 2015). Heterogeneity was assessed using the Q statistic. English and Persian search keywords and combinations included terms such as "patient bill of rights, patient rights, Iranian patient bill of rights, and Persian patient rights." A meta-analysis of the primary search sources was accomplished using STATA (version 11.0). RESULTS: Initial review included 20 articles of which 12 assessed observance rates of patient rights and three described service awareness rates of recipients concerning their personal rights. Five articles covered both topics and had an estimated 54.2% coverage based on the results of meta-analysis and the random-effects model with the heterogeneity. CONCLUSION: An Observance rate of patient bills of rights was considered somewhat adequate. However, contradictions in findings noted in this study suggest deficiencies do exist and need to be resolved. There appears a need to better describe and increase awareness rates of healthcare services by patients concerning their own bill of rights.

RESUMEN

BACKGROUND: During early spaceflights, many crewmembers did not meet their caloric requirements and consequently lost body mass during flight, as assessed by a decrease in postflight body mass. Maintaining body mass during spaceflight is crucial for maintaining crew health and monitoring body mass is thus important to medical operations as well as being a key component of human research. Determining body mass becomes difficult in a microgravity environment. METHODS: We report data from two mass measurement devices on the International Space Station (ISS): the Russian body mass measuring device (BMMD), which uses spring oscillation physics, and NASA's Space Linear Acceleration Mass Measurement Device (SLAMMD), which uses Newton's second law of motion (F = ma). RESULTS: For 25 crewmembers whose body mass was measured on both devices, significant body mass loss occurred compared to preflight (gravimetric scale) and averaged -4.4% as assessed by BMMD and -2.8% as assessed by SLAMMD. After an initial loss in the first 30 d of flight, body mass remained constant through the rest of the mission, as determined using either device. The mean difference between the two devices was 1.1 kg when the closest SLAMMD and BMMD measurements were compared (6.9 ± 6.2 d apart). Dietary intake during flight is approximately 80% of the World Health Organization estimated requirement and the decrease in body mass follows in-flight energy intake closely on average. CONCLUSION: Body mass monitoring is important for monitoring crew health during a mission and to help ensure that crewmembers consume adequate energy intake to mitigate the risks of spaceflight.

RESUMEN

BACKGROUND: Although most of the livelihood programmes target women, those that involve women and men have been evaluated as though men and women were a single homogenous population, with a mere inclusion of gender as an explanatory variable. This study evaluated the impact of WORTH Yetu (an economic empowerment intervention to improve livelihood outcomes) on household hunger, and household socioeconomic status (SES) among caregivers (both women and men) of orphaned and vulnerable children (OVC) in Tanzania. The study hypothesized that women and men respond to livelihood interventions differently, hence a need for gender-disaggregated impact evaluation of such interventions. METHODS: This is a secondary analysis of longitudinal data, involving caregivers' baseline (2016-2019) and follow-up (2019-2020) data from the USAID Kizazi Kipya project in 25 regions of Tanzania. Two dependent variables (ie, outcomes) were assessed; household hunger which was measured using the Household Hunger Scale (HHS), and Socioeconomic Status (SES) using the Principal Component Analysis (PCA). WORTH Yetu, a livelihood intervention implemented by the USAID Kizazi Kipya project was the main independent variable whose impact on the two outcomes was evaluated using multivariate analysis with a multilevel mixed-effects, ordinal logistic regression model with difference-in-differences (DiD) estimator for impact estimation. RESULTS: The analysis was based on 497,293 observations from 249,655 caregivers of OVC at baseline, and 247,638 of them at the follow-up survey. In both surveys, 70% were women and 30% were men. Their mean age was 49.3 (±14.5) years at baseline and 52.7 (±14.8) years at the follow-up survey. Caregivers' membership in WORTH Yetu was 10.1% at the follow-up. After adjusting for important confounders there was a significant decline in the severity of household hunger by 46.4% among WORTH Yetu members at the follow-up compared to the situation at the baseline (adjusted Odds Ratio (aOR) = 0.536, 95% Confidence Interval (CI) [0.521, 0.553]). The decline was 45.7% among women (aOR = 0.543 [0.524, 0.563]) and 47.5% among men (aOR = 0.525 [0.497, 0.556]). Regarding SES, WORTH Yetu members were 15.9% more likely to be in higher wealth quintiles at the follow-up compared to the situation at the baseline (aOR = 1.159 [1.128, 1.190]). This impact was 20.8% among women (aOR = 1.208 [1.170, 1.247]) and 4.6% among men (aOR = 1.046 [0.995, 1.101]). CONCLUSION: WORTH Yetu was associated with a significant reduction in household hunger, and a significant increase in household SES among OVC caregivers in Tanzania within an average follow-up period of 1.6 years. The estimated impacts differed significantly by gender, suggesting that women and men responded to the WORTH Yetu intervention differently. This implied that the design, delivery, and evaluation of such programmes should happen in a gender responsive manner, recognising that women and men are not the same with respect to the programmes.

RESUMEN

INTRODUCTION AND IMPORTANCE: Circumcision is the most common surgical procedure done in boys. Its complication varies from minor to severe. In most of African countries circumcision is often performed by traditional circumcisers. The management of penile glans amputation depends on the duration before presentation with auto-transplantation being the favorable management in acute phase of presentation. The amputation of the glans is a serious complication of circumcision because it can derange the urinary and sexual functions of a patient and may lead into psychological instability and low self-esteem. CASE PRESENTATION: We report a case of total glansectomy in a 5-year old boy who presented 12 months after surgical circumcision which was done by inexperienced medical personnel at his house. Patient presented with a pinhole urethra opening, missing glans, buried phallus with remnants of corporal bodies. Penile exploration was done, with successful significant phallus stump of about 5 cm, phallus reconstruction and meatoplasty was achieved. Partial Skin thickness grafting of the phallus stump was performed. At six- month follow up, the patient had both satisfactory cosmetic and functional outcomes. CLINICAL DISCUSSION: Total glansectomy is a rare surgical emergency with auto transplantation being the best option in acute management however successful outcome for a delayed glansectomy depends on proficient surgical penile exploration and comprehensive post operative care. Based on the clinical presentation, the goals of management for our patient were to achieve a largely patent urethral opening in the long term and to prevent further urethral meatal stenosis as well as achieving adequate phallus stump for sexual function. CONCLUSION: The amputation of the glans is a serious complication of circumcision because it can derange the urinary and sexual functions of a patient if neglected. Findings on this case report highlight the importance of raising awareness among traditional health care workers to prevent urinary and sexual function disabilities. Prevention of penile amputation can be prevented by providing proper training for circumcisers and providing public education for hospital circumcision.

RESUMEN

INTRODUCTION AND IMPORTANCE: Phaeochromocytomas are neuroendocrine neoplasms arising from chromaffin cells of the adrenal medulla and are known as intra-adrenal paragangliomas. On the contrary, paragangliomas are non-epithelial neuroendocrine neoplasms that produce other peptide hormones such as norepinephrine, epinephrine, and dopamine. In a setting with limited resources, such a condition may result in inaccurate diagnosis and treatment, which may lose a patient life if left untreated. In addition, PPGLs present a surgical challenge to many surgeons who are not thoroughly prepared. CASE PRESENTATION: We describe a case of extra-adrenal paraganglioma in a 27-year-old female who presented with symptoms of heartbeat awareness for almost a year and abdominal swelling for three months. Physical examination revealed a palpable mass around the umbilicus. Abdominal pelvic CT scan revealed a well-circumscribed mass in the central retroperitoneum displacing the IVC laterally and abdominal aorta medially with no invasion of surrounding structures. Results for pheochromocytoma workup showed elevated levels of 24-h urine Vanillylmandelic acid (VMA), and 24-h metanephrine excretion. Laparotomy through extended midline incision was done with successful excision of the tumor. The blood pressure, which was initially high normalized after surgery. DISCUSSION: The diagnosis of a malignant EAP is commonly made based on recurrence and the development of metastasis to lymph nodes or to other organs. Our patient presented with similar symptoms as pheochromocytoma. Compared to the commonly stated 10 % risk for pheochromocytomas, people with EAPs have been observed to have a 20 % to 50 % incidence of malignancy. EAPs account for at least 15 % of adult and 30 % of pediatric pheochromocytomas and are frequently found in the Zuckerkandl organ. Pheochromocytoma symptoms may manifest asymptomatically in patients with EAPs, or they may occur because of compression of nearby tissues. Surgical excision of the tumor is always the best option in managing EAP. CONCLUSION: Extra-adrenal paragangliomas can be successfully managed surgically, provided there is a multidisciplinary team, and the tumor location is well recognized and can reduce the chance of tumor metastasis.

INTRODUCTION AND CLINICAL IMPORTANCE: Brain metastases from prostate cancer are uncommon, occurring in fewer than 1 % of cases of metastatic prostate cancer. Brain metastasis can cause cerebral edema, neurologic symptoms, and may be misdiagnosed as primary brain tumors on imaging if thorough investigations are not done. It is difficult to identify and diagnose brain metastasis from prostate cancer since the intracranial metastatic process and presentation are poorly understood and limited to case studies. Most patients with brain metastases from prostate cancer exhibit a variety of metastatic symptoms; however, this patient's presentation was defined by only isolated intense headache. Our goal is to draw attention to the uncommon instance of brain metastases from prostate cancer in addition to reviewing the literature on the advances in treatment for prostatic cancer with metastasis to the brain. CASE PRESENTATION: We report the case of a 67-year-old male with metastatic prostate adenocarcinoma into the brain, presenting with isolated severe headache with no prostate cancer symptoms. Following extensive radiologic examination, metastatic deposits were detected in the left side of the brain with multiple intracerebral and cerebellar vermis lesions. Multiplanar T2 weighted abdominal pelvic MRI visualized the primary lesion in the prostate which was confirmed by histology. After a month following surgical castration, the patient reported resolved headache and resumed his daily activities. The patient's serum PSA decreased from 7.8 ng/ml to 0.3 ng/ml during a 12-months follow-up with no neurological symptoms. CLINICAL DISCUSSION: Prostate cancer rarely causes brain metastases, and the percentage of all brain metastases that originate from prostate cancer is seldom updated. It can be difficult to distinguish between primary brain lesions and metastatic brain prostate cancer, particularly when there is just one lesion present. Despite the recently developed diagnostic approaches, symptomatic patients exhibit a variety of clinical manifestations that vary depending on the location of the metastatic focus. These manifestations include headache, seizures, and focal neurological deficits, in addition to some common non-focal manifestations like confusion and memory deficits. Our patient had a PSA of 7.8 ng/ml at the beginning and the DRE results were normal, clinically prostate cancer was not thought to be the main cause of brain metastasis. Abdominal pelvic MRI was performed to investigate the primary lesion and confirmed the presence of prostate cancer with extra prostatic extensions. Adenocarcinoma prostate cancer was found to be the main cause when histopathology was done. CONCLUSION: This report reviews the literature on brain metastases from prostate cancer and points out that while very rare, brain metastases from prostatic cancer do occur and should not be overlooked, particularly in light of the recent advancements in prostatic cancer therapies that may extend the patient's survival. Gadolinium-enhanced MRI is necessary to confirm or rule out brain metastases if it is suspected, as well as to monitor prostate cancer patients.

RESUMEN

INTRODUCTION AND IMPORTANCE: Tuberculosis is prevalent in African countries especially in sub-Saharan Africa where HIV/AIDS is common. While Testicular tuberculosis is uncommon in the young as well as the elderly, pulmonary tuberculosis is commonly observed in these populations. History, physical examination, scrotal ultrasonography, and fine needle biopsy are important in diagnosis of suspected cases of testicular tuberculosis. Anti-TB therapy is the mainstay of treatment to ensure complete resolution of the lesion. However, in a few cases, orchidectomy is required for both diagnosis and treatment. When treating testicular tuberculosis, it is crucial to do a thorough assessment and investigations to exclude testicular malignancy because tuberculosis can present similarly to a testicular tumor. CASE PRESENTATION: We report a rare case of right sided isolated testicular tuberculosis in a 45-year-old male who came with right sided testicular pain and swelling. Blood workups and testicular tumor markers were all normal, scrotal ultrasound reported right heterogenous testicular mass with avascular areas of necrosis and septated fluid collections in the tunica vaginalis with features suggestive of testicular tumor. Right orchiectomy through inguinal approach was done, findings included testicular mass with pus pockets and caseous necrosis occupying the whole testis. Specimen was sent for histopathology which revealed chronic granulomatous inflammation, most likely tuberculosis, and ZN stain confirmed the diagnosis of testicular tuberculosis. In accordance with national TB guidelines, the patient had anti-TB medication for six months, and after 12-months serial follow-up, the patient had completely recovered. CLINICAL DISCUSSION: Genitourinary tuberculosis is the second most common form of extrapulmonary TB after lymph node tuberculosis. 0.5 % of genitourinary TB involves the testes; On the other hand, isolated testicular TB as presented in our patient, is extremely uncommon, thus may mimic other testicular conditions including testicular tumor, so the diagnosis is challenging. It is important to accurately diagnose testicular TB and differentiate it from other scrotal pathologies especially testicular malignancy as the management is totally different. Testicular tuberculosis is diagnosed by tissue Cytology using FNAC or after an orchidectomy. It requires early, regular, full course combined anti-tuberculosis treatment. The drug treatment method uses three to four anti-tuberculosis drugs for 6-9 months. Surgical treatment is necessary if there is no response to drug treatment or in cases of abscess formation. CONCLUSION: Testicular TB is a curable disease, but its diagnosis remains challenging. It is often missed owing to its non- specific symptoms. Thus, testicular TB should be suspected in patients with a notion of contagion or history of tuberculosis. Some of the radiological features are highly suggestive of testicular TB. FNAB could prevent unnecessary orchidectomy. In our case, the presentation was typically mimicking a testicular cancer and the patient underwent trans inguinal orchiectomy, and histology and ZN stain confirmed the diagnosis followed by subsequent six-month anti TB therapy.

RESUMEN

INTRODUCTION AND CLINICAL IMPORTANCE: Urethral duplication is a congenital anomaly characterized by the partial or full development of an auxiliary urethra as a second urethral channel varying in extent and location. The course of treatment for urethral duplication should be individualized for each patient based on the type of anomaly and the existence of symptoms. In most cases, if the ventral orthotopic urethra is normal, excision of the dorsal auxiliary urethra is almost always curative. CASE PRESENTATION: We report a case of a 13-year-old boy who presented with recurrent urinary tract infection, occasionally having drops of urine at an external pin hole meatal opening on the dorsum of the penile shaft. Several investigations were performed to confirm the presence of the dorsal accessory urethra. The patient underwent complete excision of the accessory urethra, and 12 weeks post-surgery the patient was completely asymptomatic. DISCUSSION: Urethral duplications are rare anomalies. These anomalies have been classified in various ways in the literature, including sagittal and lateral duplications, dorsal and ventral duplications. The sagittal plane is where the majority of urethral duplications occur. Based on the anatomic variation, clinical presentation and severity of the anomaly, urethral duplication treatment should be customized for each patient. An asymptomatic child may require no specific treatment. Total surgical excision of the dorsal accessory urethra appears to offer the best curative solution. CONCLUSION: Excision of the dorsal accessory urethra is usually curative when the ventral orthotopic urethra is normal. Thorough investigation before surgery is mandatory to determine the type of urethral duplication. The most common diagnostic procedures for urethral duplications include cystoscopy, KUB ultrasonography, and micturating cystourethrography. These procedures can help plan surgery, prevent complications such as neurovascular bundle injuries and urine incontinence, and improve patient self-esteem and quality of life.

RESUMEN

Key Clinical Message: The "gold standard" treatment for Squamous cell carcinoma (SCC) is radical cystectomy and different management approaches that combine chemotherapy and radiation in a neoadjuvant or adjuvant setting have been attempted with varying degrees of effectiveness. For certain individuals, partial cystectomy offers sufficient local control for muscle-invasive bladder cancer. Lifelong follow-up with cystoscopy is advised due to the possibility of potentially fatal late recurrence. Abstract: Squamous cell carcinoma (SCC) of the bladder is a rare urologic malignancy that is estimated to affect 3%-5% of the bladder cases. SCC of the bladder remains the most common subtype throughout Africa. Most of the literatures focused on the management of Urothelial carcinoma (UC), with fewer discussions on SCC management. UC typically presents with painless hematuria, whereas SCC presents with painful hematuria, bladder mass, and necroturia. SCC is mostly radioresistant and does not respond to chemotherapy. The mainstay treatment is partial cystectomy or radical cystectomy, which can be performed through open surgery or laparoscopic or robot-assisted approaches, all of which have acceptable results. We report a patient with a favorable outcome following partial cystectomy who was managed by open surgery. At the 12-month follow-up, the patient remained asymptomatic with good surgical outcomes.

RESUMEN

INTRODUCTION: Wandering spleen (WS) is a rare clinical condition found in less than 0.5 % of splenectomies and is characterized by ectopic location of the spleen within the abdomen or pelvis. It is always caused by excessive mobility brought on by the ligamentous laxity of its peritoneal attachments. Abdominal ultrasonography and computed tomography are the key imaging modalities for inquiry of WS. CASE PRESENTATION: We report the case of a 47-year-old woman who presented with painless abdominal swelling since the age of 6 years. An abdominal examination revealed a palpable, firm, mobile mass in the right lower abdomen approximately 15 × 15 cm in dimensions. A contrast CT scan of the abdomen revealed the absence of the spleen in the left upper quadrant. The patient was managed conservatively and followed for five years with favourable outcome. DISCUSSION: Failure of the dorsal mesogastrium to merge with the posterior abdominal wall in the second month of embryonic development is one of the reasons for WS. The nonsurgical conservative approach is limited to patients who are high-risk surgical candidates and have minimal symptoms and no complications. CONCLUSION: The good clinical outcome of our patient suggests that conservative non-surgical approach may be a reasonable alternative to unwarranted surgical intervention in selected clinically stable patients who have no evidence of splenic torsion or infarction, avoiding the possible complications of surgery.
