Objective: Contribute to the improvement of the anesthetic ECP of patients benefiting from MVA for incomplete abortion, Describe the methodology used for adoption of the dosage formula in Anesthesia for MVA, present the mathematical demonstration leading to the dosage formula in anesthesia for MVA. Materials and Methods: Our study was descriptive by mathematical demonstration of obtaining the equilibrium constant of the dosage formula of bipuvacaine 0.1% and Fentanyl 50 µg% adapted to the weight and specific size of patients treated anesthetically in MVA cases for incomplete abortion. We also carried out an operational research by first determining the interval where our equilibrium constant is included and secondly by means of the ends of the intervals found correlated to the ends of intervals of possible weights and sizes in the being normal human female of childbearing age to arrive at the real numerical value of the equilibrium constant of the BUKAVU Dosage Formula in the case of anesthesia for MVA during the management of incomplete abortions. Results: TWO-STAGE OPERATIONAL RESEARCH: • Determination of the interval where the equilibrium constant x = −0.95 x x by crossing the means between the extremes of volumes of anesthetic drugs giving a satisfactory sensory block without hemodynamic disturbance and the extremes of normal weight and height for women of childbearing age. We ended up with X = 0.37. Conclusion: At the end of our study which had the general objectives of contributing to the improvement of the anesthetic PEC of patients receiving MVA for incomplete abortion and specific objectives of describing the methodology used for adoption of the dosage formula in Anesthesia for MVA and present the mathematical demonstration which resulted in the dosage formula in nesthesia for MVA, it appears that the dosage formula of Bukavu, in case of intrathecal spinal analgesia of MVA for incomplete abortion provides precision on the specificity of the doses of bipuvacaine hypobarre 0.1% and Fentanyl 50 µg% reported to each patient according to her weight and height. Its application could therefore reduce morbidity and mortality and improve patient-practitioner comfort in the event of MVA for incomplete abortion following the dosage precision it provides.展开更多

Field observations and key informant interview among elder members of fisherfolk communities surrounding the Albay, Ragay, and Asid Gulfs of the Bicol Region was utilized. The study revealed that the majority of the fisherfolk parents do not want their children to continue fishing as their main source of livelihood because of potential risks, hardships, and cultural factors like collectivism, close family ties, and dependence on the elders. The parents’ aspirations were shaped by their persistence over various threats, fears, personal unfulfilled dreams, and career opportunities thru education. Most of the parents desired a college education and a safe and secure profession for their children. The study deduced that these challenges can be a contributory factor for the declining number of fisherfolks surrounding the gulfs. Influencing this sector is the factor motivating fishers in their aspirations for their children’s education. The study recommends introducing strategies for fisherfolks to develop a strong sense of hope and drive in realizing their aspirations and further research on the impact of culture, the role of women and children, and fisherfolks and their success stories.展开更多

Limitations in our technical facilities, high financial cost of ultrasound-guided biopsy often prevent us from implementing the guidelines on the practice of prostate biopsy. Methods: We conducted a retrospective and cross-sectional descriptive study comparing digital-guided and ultrasound-guided transrectal prostate biopsy of 400 patients over a period of 12 years in the Yaounde Central Hospital. We reviewed files of patients who underwent digital and ultrasound guided biopsy procedures. Data was analyzed using EPI info 7.0. Parametric variables were reported as means and standard deviations and percentages and counts were used to report categorical variables. Results: Out of the 400 patients, 292 digital-guided transrectal biopsies (73%) and 108 ultrasound-guided transrectal biopsies (27%) were performed in patients who were suspected of having prostate cancer (PCa). Patients were aged between 39 to 90 years. Both procedures were effective in identifying prostate cancer. Gleason score between 2 to 10 detected prostate adenocarcinoma for 301 patients (75.2%). The complications included anal pain, rectal bleeding, hematuria and urinary tract infections, with an occurrence rate similar for both ultrasound-guided (2.25%) and digitally-guided techniques (2.5%). Seven patients (1.75%) required hospitalization for management of complications. The mortality rate was null. Conclusion: Both techniques are effective in detecting PCa with the similar complication rates. Digital-guided trans-rectal prostate biopsy still has its place in a resource-limited setting like ours.展开更多

文摘BACKGROUND Kidney biopsy serves as a valuable method for both diagnosing and monitoring kidney conditions.Various studies have identified several risk factors associated with bleeding complications following the procedure,but these findings have shown inconsistency and variation.AIM To investigate the risk of bleeding complications following percutaneous kidney biopsy in Brunei Darussalam.We sought to explore the relevant clinical and pathological risk factors associated with these complications while also considering the findings within the broader international literature context.METHODS We conducted a retrospective study of all adult patients who underwent kidney biopsy in Brunei Darussalam from October 2013 to September 2020.The outcomes of interest were post-biopsy bleeding and the need for blood transfusions.Demographics,clinical,laboratory and procedural-related data were collected.Logistic regression analysis was used to identify predictors of outcomes.RESULTS A total of 255 kidney biopsies were included,with 11%being performed on transplanted kidneys.The majority of biopsies were done under ultrasound guidance(83.1%),with the rest under computer tomography guidance(16.9%).The most common indications for biopsy were chronic kidney disease of undefined cause(36.1%),nephrotic syndrome(24.3%)and acute kidney injury(11%).Rate of bleeding complication was 6.3%–2%frank hematuria and 4.3%perinephric hematoma.Blood transfusion was required in 2.8%of patients.No patient lost a kidney or died because of the biopsy.Multivariate logistic regression identified baseline hemoglobin[odds ratio(OR):4.11;95%confidence interval(95%CI):1.12-15.1;P=0.03 for hemoglobin≤11 g/dL vs.>11 g/dL)and the presence of microscopic hematuria(OR:5.24;95%CI:1.43-19.1;P=0.01)as independent risk factors for post-biopsy bleeding.Furthermore,low baseline platelet count was identified as the dominant risk factor for requiring postbiopsy transfusions.Specifically,each 10109/L decrease in baseline platelet count was associated with an 12%increase risk of needing transfusion(OR:0.88;95%CI:0.79-0.98;P=0.02).CONCLUSION Kidney biopsies were generally well-tolerated.The identified risk factors for bleeding and transfusion can help clinicians to better identify patients who may be at increased risk for these outcomes and to provide appropriate monitoring and management.
文摘Diesel poisoning is a rare clinical condition.On September 27,2021,a 55-year-old male who mistakenly inhaled 20 mL of diesel through a siphon was admitted to our hospital.The main symptoms were cough and asthma.Chest computed tomography(CT)showed both lungs scattered with patchy consolidation,ground-glass shadow,exudation,and pleural effusion.After 61 days of lung rehabilitation training and other supportive treatment,including oxygen therapy,postural drainage,ventilator support,bronchoalveolar lavage,hemoperfusion,continuous renal replacement therapy(CRRT),hormones,and antibiotics,the patient’s condition improved,and the patient was discharged.Through literature review,we found that lung consolidation,ground-glass shadow,nodular lesions,and pleural effusion can be observed on chest images of patients with lipoid pneumonia,with severe cases showing diffuse lesions involving both lungs,possibly secondary to respiratory failure.Children with acute critical illness deteriorates rapidly and have poor prognosis,whereas adults or patients with chronic poisoning have better prognosis after active treatment.
