Despite the negative consequences of cigarette smoking, studies to identify factors associated with cigarette smoking are scanty and little is known about this practice in the Somali region so far, so this study aimed to assess the prevalence of cigarette smoking and associated factors among adolescents in the Gode, eastern Ethiopia 2020.Methods: A community-based cross-sectional study design was employed among 341 adolescents in the Godey administration of the Somali Region, Eastern Ethiopia from July to August 2020. A systematic sampling technique was used to select study participants. Data were collected using a pretested interviewer administered questionnaire. The collected data were entered with Epi-Data version 3.1 and exported to SPSS version 22 software for statistical analysis. Multivariable logistic regression analyses were done to identify the true effect of predictor variables on the outcome variable after controlling for possible confounders. Statistical significance was declared at a p-value < 0.05.Results: Over all, the prevalence of current cigarette smoking among adolescents was found to be 21.1% (95% CI: (16.7− 25.5). Having smoker parents [AOR = 2.57, 95% CI: (1.32– 5.02)], whose friends smoke cigarette [AOR = 4.78, 95% CI: (2.12– 10.76)], and currently chewing khat [AOR = 6.01, 95% CI: (2.96– 12.23)] were significantly associated predictors of current cigarette smoking in the final model of multivariable analysis.Conclusion: The prevalence of cigarette smoking was relatively high in this study area. This study reported having smokers’ parents, having smokers’ friends and chewing khat were found to be independent predictors for cigarette smoking. Therefore, effective smoking prevention and intervention programs are required in this area.Keywords: adolescent, tobacco, cigarettes, khat, smoking, substances

Mid-crustal magma domains are the source of many basaltic eruptions. Lavas from individual eruptions are often chemically homogeneous, suggesting that they derive from single, well-mixed magma reservoirs. The 2023 to 2024 eruptions at Sundhnúksgígar in the Svartsengi volcanic system in Iceland provide an opportunity to observe the behavior of a mid-crustal magma domain at high spatial and temporal resolution by detailed sampling and geochemical characterization. We observed substantial mantle-derived geochemical variability in the products erupted in the first hours of the December 2023 and January, February, and March to May 2024 eruptions, indicating that the eruptions derived from multiple magma reservoirs, which mineral-melt equilibration pressures place in the mid crust. The unusual presence of geochemical heterogeneity in the mid-crustal magma domain provides insights into how dynamic and complex mid-crustal magma domains can be.

Objective: Analyze the duration of symptom-free intervals following laser wedge excision (LWE) for recurrent idiopathic subglottic stenosis (iSGS). Secondary aim includes evaluating the influence of patient-related or disease factors., Study Design: Retrospective review., Setting: Tertiary center., Methods: Review of iSGS patients who underwent LWE between 2002 and 2021. LWE patients without prior airway surgery were labeled LWE primary (LWEP) and those with prior history of dilation were labeled LWE secondary (LWES). A conditional frailty repeated events model was used to analyze the median time to recurrence (MTR) for each nth recurrence. Secondary analysis included stratification by use of medical therapy and initial preoperative characteristics of scar (Myer-Cotton grade, distance between the glottis and superior-most aspect of scar, D GS ; length of scar, D L )., Results: Two hundred and ten iSGS patients underwent LWE (131 LWEP, 79 LWES). The proportion of patients experiencing at least 1, 3, 6, and 12 recurrences, respectively, was 68.0% (n = 143), 40.7% (n = 85), 20.0% (n = 42), and 5.2% (n = 11). There was exponential time-shortening from the 1st to 12th recurrence (P < .0001). While MTR was 4.1 years after the first LWE, this fell to 2.8, 1.7, 1.0, and 0.7 years for the 2nd, 3rd, 6th, and 12th recurrences. Furthermore, LWEP patients experienced longer MTR than LWES counterparts within the first 6 recurrences (P < .01). There was no significant relationship between intersurgical interval and medication adherence, D L , D GS , or grade for recurrences beyond the first (P = .207, P = .20, P = .43, P = .16)., Conclusion: Symptom-free intervals in iSGS shorten with each subsequent recurrence and LWE. The difference in MTR between LWEP and LWES groups was significant within the first 6 recurrences with LWEP having longer MTR., (© 2024 American Academy of Otolaryngology–Head and Neck Surgery Foundation.)

Objective: To evaluate the impact of age on disease recurrence in idiopathic subglottic stenosis (iSGS) patients., Methods: This was a retrospective chart review of iSGS patients treated with laser wedge excision. Patients did not have prior surgery. Survival rates free of recurrence were estimated using the Kaplan-Meier methods, and associations were evaluated using Cox Proportional Hazards models., Results: Eighty-five female patients were included in the study. Most patients (68%) were postmenopausal, had first period at or before 13 years of age, had at least one full-term pregnancy (82%), were not undergoing hormone replacement therapy (93%), were not using hormonal birth control (88%), and were either partially or completely compliant with triple therapy regime (80%). There was a statistically significant average reduction in risk of recurrence of 5% for every additional year of age (p < 0.0001). When compared to patients older than 65 years of age, patients less than 35 were nearly 10 times more likely to recur (p = 0.002), and patients 55-65 and 45-55 years of age were 8 and 5 times more likely to recur, respectively (p = 0.003 and 0.009). Additionally, females on birth control showed decreased risk of recurrence of 74% compared with their counterparts (p = 0.04)., Conclusion: This is the first study to demonstrate an inverse relationship between age and disease recurrence in patients with iSGS following surgery. Using age as a surrogate for menopausal status, these results suggest that increased age and/or birth control provide a protective effect through decreased recurrence rates, possibly mediated by decreased estrogen levels., Level of Evidence: 4 Laryngoscope, 2024., (© 2024 The American Laryngological, Rhinological and Otological Society, Inc.)

Objective: To evaluate the impact of methotrexate and rituximab therapy on highly recurrent idiopathic subglottic stenosis (iSGS) patients with a negative antineutrophil cytoplasmic antibody titer cANCA(-)., Methods: This was a retrospective cohort study of highly recurrent iSGS patients who recurred within 1 year or less and were treated with methotrexate (MTX), and rituximab (RTX), or a combination of both at different time points (MTX/RTX). Average surgical durations before and after drug treatment were summarized, and the differences were calculated., Results: A total of 21 female patients with median age of 62 years were included. Fifteen patients were treated with MTX, three were treated with RTX, and five treated with both. Patients treated with immunosuppressants showed a trend toward longer intervals between operations (mean pre-drug interval: 338; mean post-drug interval: 697 days) (p-value = 0.25). Three patients did not recur following drug initiation with median follow-up of 1265 days. All three treatment groups demonstrated a trend toward increased post-drug recurrence intervals (MTX: 444 days, RTX: 374 days, MTX/RTX: 55 days), that was not statistically significant. Patients with prior dilations demonstrated longer post-drug recurrence intervals (mean pre-drug interval: 341 days, mean post-drug interval 978 days) (p-value = 0.17). Four patients in the cohort with the highest recurring disease improved from mean 129 days between operations to 509 days with drug therapy. The most common drug side effect was nausea (16%)., Conclusion: MTX and RTX may be treatment options for some highly recurrent iSGS patients. Initial results are variable and demonstrate a need for further research on drug candidacy., Level of Evidence: 3 Laryngoscope, 2024., (© 2024 The American Laryngological, Rhinological and Otological Society, Inc.)

Objective: To compare clinical outcomes in patients with and without history of tobacco use who underwent Zenker's diverticulotomy (ZD)., Study Design: Single institution retrospective review., Setting: Tertiary care academic hospital., Methods: A retrospective review of patients who underwent ZD via an open stapler, rigid endoscopic CO2 laser, stapler or harmonic scalpel, and flexible endoscopic technique from January 2006 to December 2020 was performed. Data were abstracted for patient demographics, diverticular features, and rates of adverse events and symptomatic recurrence., Results: Out of 424 patients, 146 (34.4 %) had a history of tobacco use: 126 (29.7 %) were former smokers, and 20 (4.7 %) were active smokers. In univariable cross-sectional analyses, the likelihood of postoperative bleeding, perforation, emergency department visits, unplanned readmission, or recurrence did not demonstrate an association with tobacco use history even after adjustment for age, sex, and surgical approach. Similarly, in Cox Proportional Hazards regression, tobacco use was not associated with an increased risk of recurrence, even after correcting for age, sex, and type of surgery. The median time to recurrence observed in our cohort was 11.5 years amongst non-smokers, 8.7 years amongst former smokers, and 1.2 years amongst active smokers (p = 0.94)., Conclusions: There were no significant differences in post-operative adverse events or frequency of recurrence of ZD between active, former, and non-smokers. Although underpowered and not statistically significant, median time to recurrence appears to be shorter in smokers when compared with former and non-smokers following surgery., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Inc.

Objective: To report on a series of patients with cANCA/PR3-positive, granulomatosis with polyangiitis (GPA)-associated subglottic stenosis (SGS) and evaluate response to medical maintenance therapy with rituximab versus other immunosuppressants following initial endoscopic laser excision., Study Design: Retrospective chart review., Setting: Tertiary academic center., Methods: A retrospective chart review of patients with SGS and cANCA/PR3-positive GPA who received immunosuppressive maintenance therapy following endoscopic laser excision at our institution from June 1989 to March 2020 was performed. Data pertaining to patient demographics, clinical features, medications, and endoscopic laser procedures were collected., Results: A total of 27 patients (15 women) with mean age (range) of 40 (19-59) years and mean (range) follow-up of 12.6 years (1.5-28.6) were identified. Sixteen patients (60%) had limited GPA. Six patients (24%) had previously received local intervention with open surgery (n = 1, 4%) or endoscopic techniques (n = 5, 20%). All patients experienced symptom improvement following initial CO 2 laser excision at our institution without any procedural complications or adverse events. Following initial laser excision, 15 patients (60%) were treated with rituximab and 10 patients (40%) were treated with nonrituximab immunosuppressive agents. Patients treated with rituximab were less likely to recur (P = 0.040). Limited GPA was associated with an increased incidence of recurrence (P = 0.031). Median time (years) to recurrence (range) was 3.2 (0.3-19.3) and was not significantly associated with treatment or GPA subtype., Conclusion: Endoscopic CO 2 laser excision is a safe and effective local intervention for GPA-associated SGS. Medical maintenance therapy with rituximab reduces risk of recurrence following initial laser excision relative to treatment with non-rituximab agents., (© 2024 American Academy of Otolaryngology–Head and Neck Surgery Foundation.)

Background: Oral health is crucial for overall well-being and systemic health and Humans are exposed to several bacteria after birth and will causes systemic illnesses like septicemia, respiratory, gastrointestinal, and renal issues. This study aimed to evaluate undergraduate students' knowledge, attitudes, and practices regarding toothbrush contamination and disinfection., Methods: A descriptive cross-sectional study was carried out with undergraduates from seven selected universities, including public and private universities. A closed-ended questionnaire containing 24 items was distributed to A total of 490 undergraduate students., Results: The study showed that (28.6%, n=140) had knowledge about toothbrush cleaning and disinfection. A total of (350, n=71.4%) needed to gain knowledge about toothbrush cleaning and disinfection. Fifty-two percent of the students feel that bacteria are the primary mode of toothbrush contamination. Many of the students had different ways of disinfecting toothbrushes, including, boiling a small pot of normal water (51.4%, n=252), chemical agent (31.8%, n=156), ultraviolet sanitizer (0.2%, n=4), and microwave radiation (0.2%, n=1) does not know (16.1%, n=79). Most students (76.9%, n=377) felt that toothbrush disinfection was necessary., Conclusion: Fewer students have sufficient knowledge about toothbrush contamination and practice disinfection methods, whereas most students need to be made aware of the contamination of toothbrushes and the use of disinfectant methods., Competing Interests: The authors declare no conflicts of interest related to the study, including financial, personal, or other relationships that may influence the study or its interpretation., (© 2024 Hussein et al.)

Objectives: Social determinants of health (SDOH) can influence access to cancer care, clinical trials, and oncologic outcomes. We investigated the association between SDOH, distance from treatment center, and treatment type with outcomes in human papillomavirus associated oropharyngeal squamous cell carcinoma [HPV(+)OPSCC] patients treated at a tertiary care center., Study Design: Retrospective review., Methods: HPV(+)OPSCC patients treated surgically from 2006 to 2021 were selected from our departmental Oropharyngeal Cancer RedCap database. Demographic data, treatment, and oncologic outcomes were extracted. Distance was calculated in miles between the centroid of each patient zip code and our hospital zip code (zipdistance)., Results: 874 patients (89 % male; mean age: 58 years) were identified. Most patients (96 %) reported Non-Hispanic White as their primary race. 204 patients (23 %) had a high-school degree or less, 217 patients (25 %) reported some college education or a 2-year degree, 153 patients (18 %) completed a four-year college degree, and 155 patients (18 %) had post-graduate degrees. Relative to those with a high-school degree, patients with higher levels of education were more likely to live further away from our institution (p < 0.0001). Patients who received adjuvant radiation therapy elsewhere lived, on average, 104 miles further away than patients receiving radiation at our institution (Estimate 104.3, 95 % CI 14.2-194.4, p-value = 0.02). In univariable Cox PH models, oncologic outcomes did not significantly differ by zipdistance., Conclusions: Education level-and access to resources-varied proportionally to a patient's distance from our center. Patients travelling further distances for surgical management of OPSCC were more likely to pursue adjuvant radiation therapy at an outside institution. Distance traveled was not associated with oncologic outcomes. Breaking down barriers to currently excluded populations may improve access to clinical trials and improve oncologic outcomes for diverse patient populations., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

Accurate quantification of 24(S)-hydroxycholesterol and 27-hydroxycholesterol holds substantial biological significance due to their involvement in pivotal cellular processes, encompassing cholesterol homeostasis, inflammatory responses, neuronal signaling, and their potential as disease biomarkers. The plasma determination of these oxysterols is challenging considering their low concentrations and similarities in terms of empirical formulae, molecular structure, and physicochemical properties across all human endogenous plasma oxysterols. To overcome these sensitivity and specificity issues, we developed and validated a quantification method using liquid chromatography coupled to a tandem mass spectrometry instrument. Validation studies were designed inspired by Clinical and Laboratory Standards Institute (CLSI) C62-A Guidelines. The linearity ranged between 20 and 300 nM for both oxysterols with limits of quantification at 20 nM and 30 nM for 24(S)-OHC and 27-OHC, respectively. Inter-day precision coefficient variations (CV) were lower than 10% for both oxysterols. An optimal separation of 25-OHC was obtained from 24(S)-OHC and 27-OHC with a resolution (Rs) > 1.25. The determination and validation of ion ratios for 24(S)-OHC and 27-OHC enabled another quality check in identifying interferents that could impact the quantification. Our developed and validated LC-MS/MS method allows consistent and reliable quantification of human plasmatic 24(S)-OHC and 27-OHC that is warranted in fundamental and clinical research projects., (Copyright © 2023 The Authors.

Objective: To describe the outcomes of patients undergoing open stapler versus transoral rigid and flexible endoscopic therapies for symptomatic Zenker's diverticulum., Study Design: Single institution retrospective review., Setting: Tertiary care academic hospital., Methods: We retrospectively evaluated the outcomes of 424 consecutive patients who underwent Zenker's diverticulotomy via an open stapler, rigid endoscopic CO 2 laser, rigid endoscopic stapler, rigid endoscopic harmonic scalpel, or flexible endoscopic technique from January 2006 to December 2020., Results: A total of 424 patients (173 females, mean age 73.1 ± 11.2 years) from a single institution were included. A total of 142 patients (33%) underwent endoscopic laser treatment, 33 (8%) underwent endoscopic harmonic scalpel, 92 (22%) underwent endoscopic stapler, 70 (17%) underwent flexible endoscopic, and 87 (20%) underwent open stapler. All open and rigid endoscopic procedures and most of the flexible endoscopic procedures (65%) were performed under general anesthesia. The flexible endoscopic group had a higher percentage of procedure-related perforation, defined as subcutaneous emphysema or contrast leak on imaging (14.3%). The recurrence rates were higher in the harmonic stapler, flexible endoscopic, and endoscopic stapler groups at 18.2%, 17.1%, and 17.4%, respectively, and lower in the open group (1.1%). Length of hospital stay and return to oral intake were similar among groups., Conclusion: The flexible endoscopic technique was associated with the highest rate of procedure-related perforation, while the endoscopic stapler had the lowest number of procedural complications. Recurrence rates were higher among the harmonic stapler, flexible endoscopic, and endoscopic stapler groups and lower in the endoscopic laser and open groups. Prospective comparative studies with long-term follow-up are needed., (© 2023 American Academy of Otolaryngology-Head and Neck Surgery Foundation.)

The novel coronavirus disease (COVID-19) pandemic has affected several countries worldwide, resulting in a considerable strain on healthcare systems and increased trend of self-medication practices. This study aims to evaluate the awareness of COVID-19 and the prevalence of self-medication during the pandemic among residents in Mogadishu, Somalia. A cross-sectional study was conducted using a structured and pretested questionnaire between May 2020 and January 2021. Participants from various disciplines were randomly recruited within the study location and interviewed about their self-medication practices during the pandemic. Descriptive statistics were used to summarise the respondents' information and responses to the questionnaire items. Associations between participants' demographic characteristics and specific items relating to self-medication practices were analysed using the Chi-square test. A total of 350 residents participated in the study. Approximately 63% of the participants reported having practised COVID-19 related self-medication with the main reasons being pharmacists' advice (21.4%) and having an old prescription (13.1%), whereas 37.1% did not report their reasons for self-medication. Most participants (60.4%) engaged in self-medication despite not having any symptoms and 62.9% had taken antibiotics in the last three months. Most participants were aware that no medication has been approved for COVID-19 (81.1%), the negative effects of self-medication (66.6%), and the transmission routes of the virus. Meanwhile, more than 40% of the participants have not worn a mask while outside their homes, and do not follow the international COVID-19 guidelines. The most prevalent drug used by participants for self-medication against COVID-19 was paracetamol (81.1%) and antibiotics (78%). The factors associated with awareness of COVID-19 and self-medication practices included age, gender, educational qualification, and occupation. This study revealed considerable high self-medication practices among Mogadishu residents, thus highlighting the need to promote awareness regarding the adverse effects of self-medication and sanitisation guidelines in addressing COVID-19 at the community level., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Moussa et al.

Introduction: Somali women face exceptionally high mortality and incidence rates from both breast cancer (BC) and cervical cancer (CC). They experience the highest age-standardised BC mortality rate in Africa and an age-standardised BC incidence rate of 41.7 per 100,000 women. Somalia's second-highest cancer-related mortality and incidence rates are due to CC, both behind BC. It is critical to identify the underlying factors that may influence healthcare workers' management of both cancers. At present, there is a lack of evidence regarding providers' knowledge of these two cancers and their screening in Somalia., Methods: A cross-sectional questionnaire was administered with a purposive sampling strategy to 469 healthcare professionals and students and was completed by 405 (86%). Healthcare workers were recruited from Mogadishu-based hospitals., Results: One hundred and ninety-seven healthcare professionals and 207 students completed the survey and were included in the analysis. 89% and 73% of respondents demonstrated good knowledge of BC and CC, respectively. Only 46% knew that a vaccine could prevent CC, and 89% of healthcare professionals disagreed that human papillomavirus (HPV) vaccines were available to their patients. Attitudes towards cancer screening, in addition to breast self-examination (BSE), were overwhelmingly positive. For both BC and CC, 24% reported having treated a patient and 30% reported having conducted a screen for either disease., Conclusion: Overall, while knowledge of both diseases and screening was good, there remain areas for clear educational targeting such as HPV vaccine availability and BC preventability. Attitudes to screening for both diseases were exceedingly positive but, with the exception of BSE, failed to translate into practice due to inadequate resources and patient refusal. Future investments into Somalia's chronic care management should prioritise technology necessary to conduct screenings for both diseases, expanding HPV vaccine access and understanding patients' potential motivations for refusing screening., Competing Interests: The authors declare that they have no conflicts of interests. This article is based on a thesis project for completion of graduation requirements for a Master’s in Public Health., (© the authors; licensee ecancermedicalscience.)

The clinical epidemiology of adults admitted with reduced level of consciousness (LOC) in sub-Saharan Africa (SSA) and the impact of HIV infection on the risk of mortality in this population is unknown. We secondarily analyzed data from a cohort study that enrolled 359 consecutive adults with reduced LOC presenting to Mbarara Regional Hospital in Uganda with the aim of comparing the prognostic utility of the Full Outline of Unresponsiveness (FOUR) score to the Glasgow Coma Scale (GCS) Score. For this analysis, we included 336 individuals with known HIV serostatus, obtaining clinical, laboratory, and follow-up data. We recorded investigations and treatments deemed critical by clinicians for patient care but were unavailable. We computed mortality rates and used logistic regression to determine predictors of 30-day mortality. The median GCS was 10. Persons living with HIV infection (PLWH) accounted for 97 of 336 (29%) of the cohort. The 30-day mortality rate in the total cohort was 148 of 329 (45%), and this was significantly higher in PLWH (57% versus 40%, adjusted odds ratio [aOR] 2.39: 95% confidence interval [CI]: 1.31-4.35, P = 0.0046). Other predictors of mortality were presence of any unmet clinical need (aOR 1.72; 95% CIL 1.04-2.84, P = 0.0346), anemia (aOR 1.68; 95% CI: 1.01-2.81, P = 0.047), and admission FOUR score < 12 [aOR 4.26; 95% CI: 2.36-7.7, P < 0.0001). Presentation with reduced LOC in Uganda is associated with high mortality rates, with worse outcomes in PLWH. Improvement of existing acute care services is likely to improve outcomes.

Purpose: This study reports a cross-sectional investigation to determine the antimicrobial resistance pattern of the common bacterial contaminants isolated from hospitalized patients in Mogadishu, Somalia., Materials and Methods: A total of 328 clinical samples comprising urine, blood, vaginal swab, pus aspirates, and stool were collected from a public hospital located in Mogadishu the capital city of Somalia between October 2019 to March 2020. The isolation and biochemical characterization of the bacterial isolates were performed using the conventional culture and biochemical assay tests. Similarly, antimicrobial susceptibility was determined using the Kirby-Bauer disk diffusion., Results: A total of 275 pathogenic bacteria that include Staphylococcus aureus, Escherichia coli, Pseudomonas aeroginosa, Proteus vulgare, Klebsiella pneumonia , and Salmonella spp. were detected with an overall detection rate of 78.4% (257/328). Among the bacterial pathogens isolated from clinical specimens, 152 (46.3%) were Staphylococcus aureus , 60 (18.3%) were E. coli , 10 (3.1%) Proteus vulgaris , 6 (1.8%) Klebsiella pneumonia , and 1 (0.3%) isolate was found to be Salmonella sp. The antimicrobial susceptibility assay revealed variable resistance pattern with clindamycin (40%), ampicillin (27%), vancomycin (26%), levofloxacin (23%), amoxicillin (20%), ciprofloxacin (18%) and nitrofurantoin (12%) showing the highest rate of resistance. Moreover, evaluation of multidrug resistance showed that Staphylococcus aureus had the highest multidrug resistance rate, with 19 isolates showing resistance to more than two drugs, followed by E. coli with three isolates. In contrast, each of Proteus vulgare, Salmonella sp. and Klebsiella pneumonia had one isolate each that exhibited multidrug resistance characteristics., Conclusion: The findings of this study showed the occurrence of a number antimicrobial-resistant bacterial pathogens whose prevalence varies with age and sex. Therefore, there is a need for comprehensive antimicrobial profiling of bacterial isolates during the management of patients in the hospital., Competing Interests: The authors report no conflicts of interest in this work., (© 2021 Moussa et al.)

Background: Most South Africans depend on the public sector for health services. There is an increasing demand for arthroplasty in the public sector, but a paucity of academic data regarding its cost., Objectives: To: (i) identify the factors that determine the cost of an uncomplicated primary hip arthroplasty; and (ii) make recommendations on cost optimisation., Methods: This was a cross-sectional study. Patients who met the inclusion criteria had their hospital financial records reviewed from October 2015 to March 2017. Six cost centres were utilised: inpatient admission, theatre and anaesthesia, ambulatory, prosthesis, physiotherapy and blood bank. The data were statistically analysed., Results: Fifty-five patients met the study inclusion criteria. Data were stratified into categories. Analysis of variance (ANOVA) was used to test the data, and significant differences were found in the prosthesis, inpatient admission and ambulatory cost centres at a 95% significance level. The least significant difference was used to test the ANOVA results that paired significant categories. No cost centre showed significance over the other categories. Data for the six cost centres were compared with the current literature and industry best practice. Eight recommendations are made., Conclusions: The study showed that clinicians need to be aware of procedural costing in the current financial climate. There are still opportunities to optimise cost containment in the state sector.

Background: Reduced level of consciousness (LOC) is a common cause of presentation among acutely ill adults in sub-Saharan Africa and is associated with high rates of mortality. Although the Full Outline of Unresponsiveness (FOUR) score is often used in clinical practice, its utility in predicting mortality has not been assessed in the region., Methods: We prospectively enrolled adults presenting with reduced LOC to Mbarara Regional Referral Hospital in Uganda. We recorded clinical and laboratory data and performed the FOUR and Glasgow Coma Scale (GCS) scores at admission. We used survival analysis, fit Cox proportional hazards regression models to assess the predictive properties of the two scores, and compared their performance using area under the receiver operating characteristic curve (AUROC)., Results: We enrolled 359 patients, mean (SD) age was 51 (22.2) years, and 58% (210/359) were male. The median (interquartile range) admission FOUR and GCS scores were 13.0 (3.0-16.0) and 10.0 (3.0-14.0), respectively. Subjects with the FOUR score of 0-11 had a 2.6-fold higher hazard of 30-day mortality (HR 2.6, 95% CI 1.9-3.6, p < 0.001) compared to those with the score of 12-16. Those with the GCS score of 3-8 had a 2.7-fold higher hazard of 30-day mortality (HR 2.7, 95% CI 2.0-3.8, p < 0.001) compared to those with the score of 9-15. The AUROC (95% CI) for the FOUR score and GCS score was 0.68 (0.62-0.73) and 0.67 (0.62-0.73), respectively (p = 0.825)., Conclusions: The FOUR score is comparable to the GCS score in predicting mortality in Uganda. Our findings support the introduction of the FOUR score in guiding the management of patients with reduced LOC in sub-Saharan Africa.

Introduction: Total occlusion of the left main coronary artery is a very rare finding in coronary angiography because of its highly lethal nature. Right coronary artery dominance and extensive collateral circulation are the principal determinant factors of survival after total occlusion of the left main coronary artery. The impact on the left ventricle is often significant with a profound alteration of its systolic function., Case Presentation: We describe a 52-year-old North African man, a tobacco smoker, who presented symptoms of unstable angina related to a total chronic occlusion of his left main coronary artery with a right coronary artery stenosis. Unexpectedly, the impact on his left ventricle was absent with normal dimensions and systolic function. He underwent a successful on-pump coronary artery bypass grafting with uneventful postoperative course and good recovery., Conclusions: Total occlusion of the left main coronary artery is a rare condition, the fact that the left ventricle retains a normal size and systolic function makes it exceptional, which must be kept in mind to avoid dangerous examinations and delayed treatment. Coronary artery bypass surgery should be considered the main treatment of total chronic occlusion of the left main coronary artery.

Background: Enterococcus faecium and Enterococcus faecalis are among the predominant species causing hospital-acquired infections. Currently, enterococcal infections are treated using combination therapy of an aminoglycoside with cell-wall active agents, which led to high level aminoglycoside resistance (HLAR) and vancomycin resistance (VRE) among enterococci. The aim of this study was to determine the prevalence of HLAR and the distribution of the resistance genes among clinical E. faecalis and E. faecium isolates in Malaysia., Materials and Methods: Seventy-five enterococci isolates recovered from different clinical sources were re-identified by subculturing on selective medium, Gram staining, biochemical profiling (API 20 Strep), and 16s rRNA sequencing. Antimicrobial susceptibility testing (AST) was performed using Kirby-Bauer disc diffusion, E-test, and broth microdilution methods. PCR amplification was used to detect the presence of aminoglycoside modifying enzyme (AME) genes [ aac(6')-Ie-aph(2")-Ia, aph(2")-Ib, aph(2")-Ic, aph(2")-Id, aph(3')-IIIa ]. Descriptive data analysis was used to analyze the antibiotic susceptibility profiles and the distribution of HLAR genes., Results: The majority of the isolates recovered from the clinical samples are E. faecalis (66.7%), with the highest recovery from the pus. The prevalence of HLGR (51%) is higher when compared to HLSR (45-49%). Analysis of the resistance genes showed that bifunctional genes aac(6')-Ie-aph(2")-Ia and aph(3')-IIIa contributed to the HLAR E. faecalis and E. faecium . The other AME genes [ aph(2")-Ib, aph(2")-Ic, aph(2")-Id ] were not detected in this study., Conclusion: This study provides the first prevalence data on HLAR and the distribution of the AME genes among E. faecalis and E. faecium isolates from Malaysia. These highlight the need for continued antibiotic surveillance to minimize its emergence and further dissemination., Competing Interests: The authors declare that there is no competing interest regarding the publication of this paper., (© 2019 Moussa et al.)

Background and Purpose- Rates of intracerebral hemorrhage (ICH) are estimated to be highest globally in sub-Saharan Africa. However, outcomes of ICH are poorly described and standard prognostic markers for ICH have not been validated in the region. Methods- We enrolled consecutive patients with computed tomography-confirmed ICH at a referral hospital in southwestern Uganda. We recorded demographic, clinical, and radiographic features of ICH, and calculated ICH scores. We fit Poisson regression models with robust variance estimation to determine predictors of case fatality at 30 days. Results- We enrolled 73 individuals presenting with computed tomography-confirmed ICH (mean age 60 years, 45% [33/73] female, and 14% [10/73] HIV-positive). The median ICH score was 2 (interquartile range, 1-3; range, 0-5). Case fatality at 30 days was 44% (32/73; 95% CI, 33%-57%). The 30-day case fatality increased with increasing ICH score of 0, 1, and 5 from 17%, 23%, to 100%, respectively. In multivariable-adjusted models, ICH score was associated with case fatality (adjusted relative risk, 1.48; 95% CI, 1.23-1.78), as were HIV infection (adjusted relative risk, 1.92; 95% CI, 1.07-3.43) and female sex (adjusted relative risk, 2.17; 95% CI, 1.32-3.59). The ICH score moderately improved with the addition of a point each for female sex and HIV serostatus (0.81 versus 0.73). Conclusions- ICH score at admission is a strong prognostic indicator of 30-day case fatality in Uganda. Our results support its role in guiding the care of patients presenting with ICH in the region.

The treatment of choice for incisional hernia is prosthetic repair Extensively debated issues are the materials used and the implantation site of the mesh. The authors report their personal experience with 17 cases operated on by placement of an intraperitoneal Bard Kugel Composix Mesh. From May 2003 to August 2005, 10 female and 7 male patients with incisional hernia, aged from 43 to 76 years (mean age: 65 years), were submitted to intraperitoneal prosthetic mesh implantation and monitored over a follow up period ranging from 2 to 28 months (median: 15 months). The technical aspects and the rationale for this approach are described. The advantages of this procedure are its simplicity and rapidity of execution, a reduced incidence of complications, and good tolerance in terms of patient pain and comfort. The mesh was removed in one case owing to infection of the prosthesis. Follow-up to date has revealed no instances of recurrence.

Solid pseudo-papillary tumor of the pancreas is a rare tumor that occurs predominantly in young women. It often presents as a big abdominal mass whose preoperative diagnosis appears to be difficult. It is a low- grade malignancy tumor and surgery is the mainstay of treatment. The Authors report the case of a 40 year-old woman with an abdominal mass supposed to origin from the mesenterium, diagnosed as a solid pseudo-papillary tumor of the pancreas after histological examination and treated by enucleation. Moreover literature data about epidemiology, histogenesis, diagnosis and treatment are analysed.

Background: Liver transplantation is currently offered to a limited number of patients with hepatocellular carcinoma (HCC) because of strict criteria introduced in the past to avoid recurrence. Immunosuppression represents a risk factor for tumor growth; the schedules of the immunosuppressant drugs have been modified through the years, aiming to reduce their dosage to the effective minimum., Methods: A series of 106 consecutive patients with HCC who underwent transplantation over a 15-year period at a single institution was retrospectively reviewed to ascertain whether tumor recurrence was influenced by the Milano criteria presently adopted in patient selection and whether the dosage of immunosuppressant agents administered was associated with tumor recurrence. Fifteen patients who died postoperatively and 9 with a follow-up of less than 1 year were excluded; presence of the Milano criteria, tumor-node-metastasis staging, and the cumulative dosage of the single immunosuppressants given at different intervals in the first postoperative year were analyzed in the remaining 82 patients. The influence of these variables on overall and recurrence-free survival was assessed statistically., Results: The Milano criteria did not influence recurrence-free survival, which was instead associated with the cumulative dosage of cyclosporine administered in the first postoperative year (93% 5-year recurrence-free survival for patients given low dosage vs. 76% for those given high dosage; P=0.01); T3 and T4 tumors did worse than T1 and T2 tumors., Conclusions: Current limits to transplantation for HCC might be reassessed in view of modified patient management; immunosuppression should be minimized in these patients.

Chronic hepatitis C represents a major clinical problem after liver transplantation, but factors influencing the recurrent disease have not been well characterized. We analyzed the clinical records of all the patients transplanted for hepatitis C virus (HCV)-related liver disease in our Center between 1991 and 1997. Eighty consecutive HCV-positive (+) patients (60 men, ages 28 to 64) survived more than 1 month after transplantation and were followed for a median of 45 months. Diagnosis of recurrent chronic hepatitis C was made in 38 patients (47.5%), of whom 22 had moderate/severe chronic hepatitis. Decompensated cirrhosis occurred in six patients (7.5%). No difference in patient survival was found between patients with and without hepatitis C recurrence. No association was found between recurrent hepatitis C and presumed risk factors. The method of tapering off corticosteroids was significantly associated with both hepatitis C recurrence and the severity of hepatitis. In patients receiving a higher daily prednisone dose, 12 months after transplantation, the proportion of recurrent hepatitis C was 35.7% versus 66.6% (P = .02; odds ratio [OR], 3.6; 95% confidence interval (CI): 1.25 to 10.36), and among patients receiving a higher daily prednisone dose, 6 months after transplantation, the proportion of moderate/severe chronic hepatitis C was 40% versus 89% (P = .03; OR: 0.08, 95% CI: 0.008 to 0.84). Finally, prednisone dose at month six was significantly associated with disease-free survival of the liver graft. In conclusion, our results seem to indicate that in HCV-infected liver transplant recipients, a long-term treatment with corticosteroids, slowly tapered off over time, may prevent the more aggressive forms of recurrent liver disease.

Blood samples from 3000 Somali camels (Camelus dromedarius) were examined for trypanosome infection. Of these, 160 (5.33%) were infected with Trypanosoma evansi, one (0.03%) with T. congolense and one (0.03%) with T. brucei. Camel trypanosomiasis occurred in most areas of tabanid infestation throughout the country. The tabanids Philoliche zonata and P. magretti are incriminated as the major vectors of the disease.
