A Comprehensive Review of HIV-Associated Tuberculosis: Clinical Challenges and Advances in Management.

Human immunodeficiency virus (HIV) and tuberculosis (TB) are two of the most pressing global health issues, each contributing significantly to morbidity and mortality worldwide. This review provides a comprehensive analysis of HIV-associated TB (HIV-TB), focusing on the clinical challenges and advancements in its management. HIV-positive individuals are at a heightened risk of developing active TB due to the immunosuppressive effects of the virus, which complicates both diagnosis and treatment. The interplay between these two diseases exacerbates health outcomes, presenting unique challenges related to drug interactions, adherence to treatment regimens, and management of adverse effects. This review explores the current diagnostic approaches, including advances in testing technologies and screening strategies, and examines treatment protocols, highlighting the integration of antiretroviral therapy with TB treatment. Special considerations for managing HIV-TB in various populations, such as children, pregnant women, and the elderly, are discussed. Additionally, the review addresses public health strategies for prevention and the impact of socio-economic and healthcare system factors on disease management. Finally, it highlights recent research innovations and future directions aimed at improving outcomes for individuals with HIV-TB. By synthesizing the latest evidence and clinical practices, this review aims to enhance understanding and guide effective management of this critical co-infection, ultimately contributing to reduced global burden and improved patient care.

Male and female disparities in breast cancer epidemiology: A comparative cross-sectional analysis of a Brazilian cohort (2017-2021).

Male breast cancer (MBC) is a rare condition, accounting for approximately 1 % of all breast cancer cases. Nevertheless, the paucity of MBC-specific research has impeded a thorough understanding of MBC. In this study, we aimed to delineate the epidemiological implications of MBC in Brazil and benchmarked it against female breast cancer (FBC). This retrospective study analyzed data from the DATASUS database (2017-2021), which assessed the incidence of breast cancer in both sexes. All statistical analyses were performed using descriptive statistics and inferential methods, with significance set at a 95 % confidence interval. We identified 4,326 (1.7 %) and 233,793 (94.2 %) patients with MBC and FBC, respectively, in Brazil. Despite the general population concentration in the Southeast, MBC cases were more prevalent in the Northeast (p < 0.0004). At breast cancer diagnosis, males were typically older (mean age 59.5 [±10.2] years) than females (mean age 55.7 7 [±9.8] years). MBC was more commonly diagnosed clinically compared with FBC, which was most commonly diagnosed via screening. Surgical diagnostics were twice as likely in males, who also more frequently presented with advanced disease stages (stages III and IV; 72.8 % vs. 59.3 %), leading to a higher rate of mastectomy. Treatment was initiated earlier in males than in females. Although MBC comprises a minority of breast cancer cases, it is more frequently diagnosed at an advanced stage compared with FBC and necessitates aggressive treatment. Our study also underscores the potential benefit of prompt initiation of therapy and need for tailored clinical approaches in patients with MBC.

Effect of add-on naldemedine treatment in patients with cancer and opioid-induced constipation insufficiently responding to magnesium oxide: a pooled, subgroup analysis of two randomized controlled trials.

OBJECTIVE: To evaluate the additive effect of naldemedine tosylate (naldemedine) on opioid-induced constipation in cancer patients insufficiently responding to magnesium oxide treatment. METHODS: We combined two randomized, double-blind, placebo-controlled, phase IIb and III trials of naldemedine and conducted a post hoc subgroup analysis. We evaluated the effect and safety of naldemedine in 116 patients who received naldemedine in addition to magnesium oxide (naldemedine group) and 117 patients who received placebo in addition to magnesium oxide (placebo group). Both groups included patients insufficiently responding to magnesium oxide for opioid-induced constipation. Effect was assessed using spontaneous bowel movement responder rate, complete spontaneous bowel movement responder rate, changes in spontaneous bowel movements and complete spontaneous bowel movements. Safety was also assessed. RESULTS: During the 2-week treatment period, the responder rates for spontaneous bowel movement and complete spontaneous bowel movement were 73.3 and 43.1% in naldemedine group, respectively, which were significantly higher (P < 0.0001) than 41.9 and 14.5% in placebo group, respectively. Median time to first spontaneous bowel movement and first complete spontaneous bowel movement was significantly shorter (P < 0.0001) in the naldemedine group (4.0 and 21.3 h, respectively) than in the placebo group (27.7 and 211.7 h, respectively). The incidence of adverse events and diarrhoea was significantly higher (P < 0.05) in the naldemedine group than in the placebo group, while the incidence of serious adverse events and severe diarrhoea was not significantly different between the naldemedine and placebo groups. CONCLUSION: The study suggested the addition of naldemedine as an effective treatment option for opioid-induced constipation in cancer patients insufficiently responding to magnesium oxide treatment.

Postpartum Psychosis as a Precursor to Schizophrenia: A Comprehensive Review.

Postpartum psychosis (PP) is a rare and severe mental health disorder occurring shortly after childbirth, characterized by symptoms such as delusions, hallucinations, and intense mood swings. This review examines the potential link between PP and the later development of schizophrenia, a chronic psychiatric condition that typically emerges in late adolescence or early adulthood. By reviewing existing literature and analyzing epidemiological and clinical data, this review aims to clarify whether PP can be a precursor to schizophrenia. Findings suggest that while the transition from PP to schizophrenia is not inevitable, there is an increased risk, with some studies indicating that a subset of women with PP may develop a chronic psychotic disorder later on. This underscores the importance of early detection, ongoing monitoring, and targeted interventions. The review emphasizes the need for improved diagnostic practices and preventive measures to better manage PP and its potential long-term effects. Enhanced understanding of this relationship can inform more effective treatment strategies and support better mental health outcomes for new mothers. Future research should focus on refining risk assessment tools, exploring underlying mechanisms, and developing comprehensive management approaches to address the challenges associated with PP and its potential progression to schizophrenia.

The Effect of Conservative vs. Radical Treatment of Ameloblastoma on Recurrence Rate and Quality of Life: An Umbrella Review.

Ameloblastoma is a rare, benign, but locally aggressive odontogenic tumor that originates from the epithelial cells involved in tooth development. The surgical approach to treating an ameloblastoma depends on the type, size, location, and extent of the tumor, as well as the patient's age and overall health. This umbrella review's aim is to summarize the findings from systematic reviews (SRs) and meta-analyses on the effect of radical or conservative treatment of ameloblastoma on the recurrence rate and quality of life, to evaluate the methodological quality of the included SRs and discuss the clinical management. Three electronic databases (PubMed, Scopus, The Cochrane Library) were checked. The primary outcome was the recurrence rate after surgical treatment, while the secondary outcomes were the post-operative complications, quality of life, esthetic, and functional impairment. The methodological quality of the included SRs was assessed using the updated version of "A Measurement Tool to Assess Systematic Review" (AMSTAR-2). Eighteen SRs were included. The quality of the included reviews ranged from critically low (three studies) to high (eight studies). Four studies were included in meta-analysis, and they revealed that the recurrence rate is about three-times more likely in the conservative treatment group compared to the radical treatment group, and this result is statistically significant. Despite the high recurrence rate, the latter was more appropriate in the case of smaller lesions and younger patients, due to better post-operative quality of life and reduced functional and esthetic impairments. Based on the results of this overview, conservative treatment may be recommended as the first-line approach for intraosseous ameloblastoma not involving soft tissue. However, given the expectation of a higher recurrence rate, it is advisable to reduce the interval between follow-up visits. However, further prospective studies are needed to establish the best treatment choice and follow-up period.

A retrospective observational study of mangrove pit viper envenomation presented to selangor middle zone cluster hospitals in Malaysia.

OBJECTIVE: There is very limited published experience on mangrove pit viper envenomation in the medical literature. This study aims to analyze the clinical characteristics, treatment modalities and outcomes of patients presenting to Selangor middle zone cluster Hospitals in Malaysia with confirmed mangrove pit viper bites. METHODS: We conducted a retrospective observational study, reviewing medical records of patients treated for mangrove pit viper bites between July 1, 2020 to June 30, 2023. Data on patient demographics, clinical characteristic, laboratory findings, treatment modalities and clinical outcomes were collected and analyzed. RESULTS: A total of 25 patients were included in this study. The majority of the patients were male (n = 23, 92%) with the mean age of 38.7 ± 17.6 years. Most frequent anatomical region involved is foot (n = 12, 48%). Common clinical presentation included localized pain (n = 24, 96%), swelling (n = 22, 88%) and fang mark (n = 22, 88%). Systemic symptoms were less common, with 1 patient exhibiting coagulopathy with clinical bleeding at 28 h post bite. Antivenom was administered to 68% (n = 17) of the patients. The majority of the patients (n = 23, 92%) recovered without significant morbidity while 8% (n = 2) of the patients developed skin infection that required antibiotic therapy. No fatalities were reported. CONCLUSION: Mangrove pit viper envenomation encountered in these regions predominantly causes local symptoms while systemic symptoms were less common. This study provides a glimpse to the clinical characteristics and management of mangrove pit viper envenomation, coagulopathy may be delayed due to characteristic of the snake venom and patient's preexisting illness. Further research is needed to enhance our understanding of this snakebite envenomation.

Do corticosteroids affect immunotherapy efficacy in malignancy? - A systematic review.

BACKGROUND: Early studies indicated that corticosteroids may limit the survival benefit from immunotherapy. We conducted this systematic review to evaluate the effect corticosteroids have on immunotherapy in patients with malignancy, when adjusted for potentially confounding effects of corticosteroids given for palliative indications. METHODS: Three electronic databases (PubMed, Embase and Medline) were searched on 1 February 2023. Studies that measured response or survival to immunotherapy in people receiving corticosteroids for non-cancer indications compared to either no corticosteroids or corticosteroids for cancer-related indications were included. Studies exclusively evaluating the effect of corticosteroids administered for immune-related adverse events (irAE) were excluded to avoid immortal time bias. Pooled odds and hazard ratios with 95% confidence intervals (CI) were calculated using a random effects model. Study heterogeneity was assessed using the I2 statistic, and publication bias was evaluated by funnel plot and Egger's regression model. RESULTS: Eight thousand four hundred and twenty-six titles were identified on our search. Eight studies met our inclusion criteria for meta-analysis. Administration of corticosteroids does not have a statistically significant effect on survival and response to immunotherapy when administered for non-cancer-related indications, with a pooled odds ratio for overall response rate 1.01 (95% CI 0.64-1.60); pooled hazard ratio (HR) for progression free survival 0.87 (95% CI 0.68-1.12); and pooled HR for overall survival 0.79 (95% CI 0.59-1.05). CONCLUSION: This systematic review indicates that administration of corticosteroids does not affect response to immunotherapy nor survival outcomes, when removing confounding palliative corticosteroid indications. These results are limited by the retrospective nature of the studies included, small sample sizes, lack of information about corticosteroid dosing and the inclusion of irAE in two of the studies which could bias the results.

Interactions Between Gastroesophageal Reflux Disease and Diabetes Mellitus: A Systematic Review of Pathophysiological Insights and Clinical Management Strategies.

This systematic review elucidates the complex interplay between gastroesophageal reflux disease (GERD) and diabetes mellitus, integrating findings from various studies to highlight pathophysiological connections and effective clinical management strategies. Our examination reveals that mechanisms such as delayed gastric emptying and autonomic neuropathy significantly contribute to the exacerbation of GERD symptoms in diabetic patients, influencing clinical outcomes and treatment efficacy. The review underscores the necessity of multidisciplinary approaches in treating these comorbid conditions and advocates for therapeutic strategies that simultaneously address GERD and diabetes, such as the use of prokinetic agents and tailored surgical interventions like laparoscopic Roux-en-Y gastric bypass. This synthesis advances our understanding and proposes a foundation for future research and clinical practice, aiming to improve the quality of life and treatment outcomes for affected patients. This work contributes significantly to gastroenterology and endocrinology, providing a comprehensive resource for clinicians and researchers alike.

Clinical guidance based on MRI for the management of temporomandibular joint synovial chondromatosis: One institution's experience.

The aim of this retrospective observational study was to introduce a comprehensive MRI evaluation criterion for the clinical management of synovial chondromatosis of the temporomandibular joint (TMJ-SC). Patients received different treatments according to the MRI evaluation system: bone erosion, extent, articular disc condition, location, maturity, and size of loose body. At least a 2-year follow-up was completed to assess tumor recurrence, visual analogue scale score for pain (VAS) and maximum interincisal opening (MIO). Of the 195 patients included for TMJ-SC, 34 received arthroscopy and 161 received open surgery. Among the patients with significant extent of SC, 32 received temporary resection of the condylar neck or zygomatic arch and 2 received treatment combined with ear, nose and throat(ENT). 28 received articular disc reconstruction and 56 received disc repositioning. Patients showed good recovery of joint function with only two cases of tumor recurrence at an average follow-up of 75.1 months after surgery. The MIO had improved from 30.2 mm to 40.0 mm(P < 0.0001) and VAS had decreased from 5.1 to 0.78(P < 0.0001).The preoperative MRI evaluation principles has been effective in selecting appropriate surgical options.

Agências de regularização técnica odontológica em relação ao manejo clínico em crianças: uma revisão de literatura / Dental technical regularization agencies in relation to management clinic in children: a review of the literature

O manejo clínico em Odontopediatria é individual, podendo variar nas diversas culturas mundiais. O objetivo desta revisão de literatura é reunir as principais diretrizes de diferentes países ao redor do mundo, incluindo o Brasil, visando identificar como em cada lugar o uso das técnicas de comportamento são aplicadas e sua eficiência. Inicialmente, foram selecionados os principais guias nacionais e internacionais, sendo eles retirados da Associação Internacional de Odontopediatria (IAPD) e Associação Americana de Odontopediatria (AAPD), além de artigos de diferentes países e continentes, como Argentina, Brasil, Europa e Ásia, também foram analisados se o protocolo dos principais guias estão condizentes com os protocolos do Departamento de Clínica Infantil da Faculdade de Odontologia de Ribeirão Preto - USP. Os resultados obtidos nos guias para manejo clínico odontológico brasileiro, americano, internacional e os artigos estudados recomendam inicialmente utilizar técnicas menos invasivas, com o intuito proporcionar um atendimento tranquilo e sem criar traumas para a criança, uma vez que muito do comportamento não cooperativo vem de experiências anteriores traumáticas. Entretanto, técnicas avançadas podem ser utilizadas para casos mais desafiadores. Concluímos com o estudo dos guias e artigos, que o cirurgião dentista possui diversas técnicas a serem aplicadas para que o atendimento infantil seja atraumático e restabelecer saúde ao paciente.

Clinical management in Pediatric Dentistry is individual and varies across different cultures around the world. The objective of this literature review is to bring together the main guidelines from different countries around the world, including Brazil, aiming to identify how the use of behavioral techniques are applied and their efficiency in each place. Initially, the main national and international guides were selected, taken from the International Association of Pediatric Dentistry (IAPD) and the American Association of Pediatric Dentistry (AAPD), as well as articles from different countries and continents, such as Argentina, Brazil, Europe and Asia, as well as It was analyzed whether the protocols of the main guides are consistent with the protocols of the Children's Clinic Department of the Faculty of Dentistry of Ribeirão Preto - USP. The results obtained in the guides for Brazilian, American and international dental clinical management and the articles studied recommend initially using less invasive techniques, with the aim of providing calm care and without creating trauma for the child, since much of the uncooperative behavior comes from previous traumatic experiences. However, advanced techniques can be used for more challenging cases. We conclude from studying the guides and articles that the dental surgeon has several techniques to be applied so that child care is atraumatic and restores health to the patient.

Adrenal Referral Pattern: Management of Patients With an Adrenal Incidentaloma.

INTRODUCTION: Adrenal incidentalomas (AIs) are found in 3%-4% of abdominal computed tomography scans. Timely evaluation of their functional status and malignant potential is necessary to guide nonoperative surveillance or surgery. This study aims to evaluate the adherence of referring service patterns to the American Association of Endocrine Surgeons and American Association of Clinical Endocrinologists guidelines for the biochemical workup of AIs at a tertiary surgical clinic. METHODS: We conducted a retrospective study of 125 patients evaluated for AIs at the endocrine surgery clinic between 2017 and 2022. Information on patient demographics, referral source, and reasons for referral was collected. The appropriateness of the biochemical workup for AIs by referring physicians was assessed. Statistical analyses included chi-square and Kruskal-Wallis tests. RESULTS: Referrals came from endocrinologists (44.8%), other subspecialists (31.2%), and primary care physicians (PCPs) (19.2%). Among 125 patients, diagnoses included benign adrenal masses (52.8%), aldosteronomas (10.4%), cortisol-secreting tumors (15.2%), pheochromocytomas (12.8%), and metastatic masses (4.0%). Endocrinologists were more likely to conduct a complete biochemical workup compared to other subspecialties and PCPs (P < 0.001). Eighty-three (66.4%) patients underwent adrenalectomy, with those referred by endocrinologists more likely to undergo surgery than those referred by other subspecialties and PCPs (P < 0.001). There was no significant difference in the time from the initial clinic visit to surgery by referral source (P > 0.05). CONCLUSIONS: Over half of AIs referrals to the endocrine surgery clinic came from subspecialists and PCPs rather than endocrinologists. Familiarizing all referring physicians with American Association of Endocrine Surgeons/Association of Clinical Endocrinologists guidelines may reduce undiagnosed functional AI cases and facilitate timely surgical management.

Predicting high blood pressure using machine learning models in low- and middle-income countries.

Responding to the rising global prevalence of noncommunicable diseases (NCDs) requires improvements in the management of high blood pressure. Therefore, this study aims to develop an explainable machine learning model for predicting high blood pressure, a key NCD risk factor, using data from the STEPwise approach to NCD risk factor surveillance (STEPS) surveys. Nationally representative samples of adults aged 18-69 years were acquired from 57 countries spanning six World Health Organization (WHO) regions. Data harmonization and processing were performed to standardize the selected predictors and synchronize features across countries, yielding 41 variables, including demographic, behavioural, physical, and biochemical factors. Five machine learning models - logistic regression, k-nearest neighbours, random forest, XGBoost, and a fully connected neural network - were trained and evaluated at global, regional, and country-specific levels using an 80/20 train-test split. The models' performance was assessed using accuracy, precision, recall, and F1 score. Feature importance analysis identified age, weight, heart rate, waist circumference, and height as key predictors of blood pressure. Across the 57 countries studied, model performances varied considerably, with accuracy ranging from as low as 58.96% in some models for specific countries to as high as 81.41% in others, underscoring the need for region and country-specific adaptations in modelling approaches. The explainable model offers an opportunity for population-level screening and continuous risk assessment in resource-limited settings.

Atypical cancer risk profile in carriers of Italian founder BRCA1 variant p.His1673del: Implications for classification and clinical management.

BACKGROUND: BRCA1:c.5017_5019del (p.His1673del) is a founder variant relatively frequent in Northern Italy. Despite previous suggestion of pathogenicity, variant classification in public databases is still conflicting, needing additional evidence. METHODS: Maximum likelihood penetrance of breast/ovarian and other cancer types was estimated using full pedigree data from 53 informative Italian families. The effect of the variant on BRCA1-ABRAXAS1 interaction was assessed using a GFP-fragment reassembly-based PPI assay. Results were combined with additional data from multiple sources to classify the variant according to ACMG/AMP classification rules specified for BRCA1/2. RESULTS: Variant-carriers displayed increased risk for ovarian cancer (HR = 33.0, 95% CI = 7.0-155.0; cumulative risk at age 70 = 27.6%, 95% CI = 12.6-40.0%) but not for breast cancer (HR = 0.7, 95% CI = 0.2-2.2). An increased risk of uterine cancer (HR = 8.0, 95% CI = 1.03-61.6) emerged, warranting further evaluation. Likelihood-ratio in favor of pathogenicity was 98898642.82 under assumption of standard BRCA1 breast and ovarian penetrance, and 104240832.84 after excluding breast cancer diagnoses (based on penetrance results). Functional analysis demonstrated that the variant abrogates the BRCA1-ABRAXAS1 binding, supporting the PS3 code assignment within the ACMG/AMP rule-based model. Collectively, these findings allowed to classify the variant as pathogenic. CONCLUSION: Pathogenicity of BRCA1:c.5017_5019del(p.His1673del) has been confirmed; however, breast cancer risk in Italian families is not increased, unlike in families from other countries and in carriers of most BRCA1 pathogenic variants. The knowledge of atypical risk profiles for this and other variants will pave the way for personalized management based on specific genotype.

Rising pertussis cases and deaths in China: current trends and clinical solutions.

Pertussis, an acute respiratory infection caused by Bordetella pertussis, has recently experienced a dramatic increase in incidence and associated deaths in China, drawing significant clinical attention. This article retrospectively analyzes national data on pertussis incidence and mortality from 2010 to 2024, exploring potential factors contributing to this trend. It also discusses strategies for enhancing vaccination programs, improving early diagnosis and treatment, and optimizing the clinical management of high-risk infants, with the aim of addressing the challenges posed by the current pertussis epidemic.

What influences ambulance clinician decisions to pre-alert emergency departments: a qualitative exploration of pre-alert practice in UK ambulance services and emergency departments.

BACKGROUND: Ambulance clinicians use pre-alerts to inform receiving hospitals of the imminent arrival of a time-critical patient considered to require immediate attention, enabling the receiving emergency department (ED) or other clinical area to prepare. Pre-alerts are key to ensuring immediate access to appropriate care, but unnecessary pre-alerts can divert resources from other patients and fuel 'pre-alert fatigue' among ED staff. This research aims to provide a better understanding of pre-alert decision-making practice. METHODS: Semi-structured interviews were conducted with 34 ambulance clinicians from three ambulance services and 40 ED staff from six receiving EDs. Observation (162 hours) of responses to pre-alerts (n=143, call-to-handover) was also conducted in the six EDs. Interview transcripts and observation notes were imported into NVIVO and analysed using thematic analysis. FINDINGS: Pre-alert decisions involve rapid assessment of clinical risk based on physiological observations, clinical judgement and perceived risk of deterioration, with reference to pre-alert guidance. Clinical experience (pattern recognition and intuition) and confidence helped ambulance clinicians to understand which patients required immediate ED care on arrival or were at highest risk of deterioration. Ambulance clinicians primarily learnt to pre-alert 'on the job' and via informal feedback mechanisms, including the ED response to previous pre-alerts. Availability and access to clinical decision support was variable, and clinicians balanced the use of guidance and protocols with concerns about retention of clinical judgement and autonomy. Differences in pre-alert criteria between ambulance services and EDs created difficulties in deciding whether to pre-alert and was particularly challenging for less experienced clinicians. CONCLUSION: We identified potentially avoidable variation in decision-making, which has implications for patient care and emergency care resources, and can create tension between the services. Consistency in practice may be improved by greater standardisation of guidance and protocols, training and access to performance feedback and cross-service collaboration to minimise potential sources of tension.

Health professionals' experiences and views on obstetric ultrasound in Tanzania: A cross-sectional study.

BACKGROUND: Obstetric ultrasound is considered important for determining gestational age, identifying single or multiple pregnancies, locating the placenta and fetal anomalies and monitoring fetal growth and pregnancy-related complications in order to improve patient management. OBJECTIVES: To explore health professionals' perspectives on different aspects of obstetric ultrasound in Tanzania regarding self-reported skills in performing ultrasound examinations and what could improve access to and utilization of obstetric ultrasound in the clinical setting. DESIGN: Cross-sectional study. MATERIAL AND METHODS: Data was collected between November and December 2017 using a questionnaire based on previous qualitative research results from the CROss Country UltraSound Study (CROCUS Study). Seventeen healthcare facilities in 5 urban and semiurban municipalities in the Dar-es-Salaam region were included, with 636 health professionals participating (physicians, n = 307 and midwives/nurses, n = 329). RESULTS: Most health professionals (82% physicians, 81% midwives/nurses) believed that obstetric ultrasound was decisive in the clinical management of pregnancy. Results indicate proficiency gaps across disciplines: 51% of physicians and 48.8% of midwives/nurses reported no or low-level skills in assessing cervical length. Similarly, deficiencies were observed in evaluating the four-chamber view of the fetal heart (physicians: 51%, midwives/nurses: 61%), aorta, pulmonary artery (physicians: 60.5%, midwives/nurses: 65%) and Doppler assessments (umbilical artery: physicians 60.6%, midwives/nurses 56.1%). Compared to midwives/nurses, physicians were significantly more likely to agree or strongly agree that utilization would improve with more ultrasound machines (odds ratio (OR) 2.13; 95% confidence intervals (CI) 1.26-3.61), better quality of ultrasound machines (OR 2.27; 95% CI 1.10-4.69), more training for health professionals currently performing ultrasound (OR 2.11; 95% CI 1.08-4.17) and more physicians trained in ultrasound (OR 2.51; 95% CI 1.30-4.87). CONCLUSIONS: Improving the provision of obstetric ultrasound examinations in Tanzania requires more and better-quality ultrasound machines, enhanced training for health professionals and an increased number of physicians trained in ultrasound use. To further increase the accessibility and utilization of obstetric ultrasound in maternity care in Tanzania, it is essential to provide training for midwives in basic obstetric ultrasound techniques.

A study reporting on health professionals' insights and skills regarding pregnancy scans in TanzaniaThis study, conducted in Tanzania, explores health professionals' perspectives on obstetric ultrasound, an important component believed to increase antenatal care attendance in low-income countries. The research was carried out through a cross-sectional study involving 636 health professionals, primarily physicians and midwives/nurses, to assess their self-reported skills in performing obstetric ultrasound examinations and identify factors that could enhance access to and utilization of obstetric ultrasound in clinical settings. The findings highlight that most health professionals view obstetric ultrasound as crucial in managing pregnancy. However, there is a notable discrepancy in the perceived skills between physicians and midwives/nurses, especially in basic obstetric ultrasound examinations. A majority of health professionals reported either no skills or low-level skills in assessing various aspects like cervical length, fetal heart (four-chamber views), aorta, pulmonary artery and Doppler (umbilical artery). The study suggests that improving access and utilization of obstetric ultrasound could be achieved through increased availability of quality ultrasound machines and enhanced training. Physicians expressed a stronger belief in the positive impact of more ultrasound machines, better machine quality, additional training for current ultrasound examiners and more physicians trained in ultrasound. The data underscores the potential for enhancing obstetric ultrasound provision in Tanzania by investing in better technology, providing more training for healthcare professionals and increasing the number of physicians skilled in ultrasound use. Furthermore, the study recommends targeted training for midwives to enhance their proficiency in basic obstetric ultrasound, ultimately contributing to improved accessibility and utilization of obstetric ultrasound in maternity care in Tanzania.

Patients returning to the emergency department with symptoms of cauda equina syndrome: do the symptoms differ with radiological cauda equina compression?

BACKGROUND: The guidance for clinicians on who requires further investigation when suspecting cauda equina syndrome has become clearer in England following the publication of the national recommendations. This does not have specific advice for those patients who have had recent imaging with no compression, returning to a healthcare provider with a change in symptoms. These cases can cause difficulty for clinicians with limited access to imaging who can often be reassured by previous imaging. METHOD: This study presents a retrospective review of the case notes of 45 patients presenting on two occasions to the same Emergency Department who underwent magnetic resonance imaging due to the clinical diagnosis of cauda equina syndrome. Those with compression of the cauda equina on the second visit were compared to those without a compressive cause for their symptoms. RESULTS: Patients presenting with an increased number of clinical symptoms associated with cauda equina syndrome on their return visit were more likely to have compression of the cauda equina on imaging. CONCLUSION: The small numbers in this study would suggest caution, however, if patients present with an increasing number of symptoms further imaging should be considered, even with previous reassuring scans.
