RESUMO

Objective: To compare the perception of dental students and faculty members regarding the attributes of effective clinical teachers. METHODS: This cross-sectional study was conducted at the Dow University of Health Sciences, Karachi, from August 2021 to November 2021, and comprised of third and final year dental students and associated clinical faculty members from three dental colleges in the city. Data was collected using the modified version of a pre-validated questionnaire. Data was analysed using SPSS 25. RESULTS: Of the 200 students approached, 169(84.5%) responded; 135(79.9%) females and 34(20.1%) males with mean age 21.78±1.099 years (range: 19-26 years). Of the 59 teachers approached, 49(83%) responded; 33(67.3%) females and 16(32.7%) males with mean age 31.59±5.041 years (range: 23-49 years). The students found record-keeping a tiresome task 69(42%), while teachers regarded it essential for clinical development. Unlike teachers, the students were unable to identify the relevance of clinical objectives and they also did not appreciate teachers' involvement in clinical procedures. For other domains regarding personal traits, teaching methods and clinical skills, both groups had similar responses. Conclusion: There was generally a similarity of opinions among students and teachers regarding the essential qualities of effective dental clinical teaching.

RESUMO

The clinical utility of transesophageal echocardiography (TEE) is well-established for patients undergoing cardiac surgery. With the increase in percutaneous structural heart disease procedures that rely on TEE for procedural guidance, the use of TEE probes is expanding. Although there are well-established protocols for routine cleaning and decontaminating TEE probes between patient use, there is a lack of awareness and misconceptions about maintaining TEE probes' structural and electrical integrity. The electrical leakage test (ELT) is routinely performed between patient use. From a patient safety standpoint, the ELT is necessary to ensure the longevity of this expensive equipment and prevent disruptions to the workflow in a busy department caused by TEE probes being decommissioned due to probe damage. This technical communication aims to highlight the importance of maintaining TEE probes' structural and electrical integrity. The article also highlights and discusses probe handling techniques between patient use, emphasizing the ELT to ensure patient safety and compliance with national and international standards.

RESUMO

OBJECTIVE: To determine the positive predictive value of Breast Imaging Reporting and Data System category IV lesions, and to evaluate interobserver agreement among radiologists in interpreting the subcategories. Method: The cross-sectional study was conducted at the Dow Institute of Radiology, Dow University of Health Sciences, Karachi, from September 2018 to February 2019, and comprised adult females aged 30-60 years diagnosed with Breast Imaging Reporting and Data System IV. Already diagnosed breast carcinoma patients were excluded. The positive predictive value of Breast Imaging Reporting and Data System category IV was calculated using histopathology findings as the gold standard. Data was analysed using SPSS 22. RESULTS: There were 191 patients with a mean age of 49.01±11.79 years. Positive family history of breast cancer was found in 33(17.3%) subjects. Category IV-A was noted in 53(28.0%) subjects, IV-B in 45(23.6%) and IV-C in 93(48.7%). The overall positive predictive value of category IV was 151(79.1%), IV-A 27(50.9%), IV-B 35(77.7%) and IV-C 89(95.6%). Malignant disease was significantly associated with architectural distortion and suspicious microcalcifications (p<0.001). A good agreement was observed in the categorisation of Breast Imaging Reporting and Data System category IV between observers 1 and 2 (kappa 0.85, 95% confidence interval: 0.70-0.99), between observers 1 and 3 (kappa 0.77, 95% confidence interval: 0.61-0.94), and between observers 2 and 3 (kappa 0.63, 95% confidence interval: 0.43-0.83). CONCLUSIONS: Breast Imaging Reporting and Data System BI-RADS IV was found to have a high positive predictive value in the diagnosis of breast cancer. Besides the interobserver agreement in terms of identifying BI-RADS IV subcategories was good.

RESUMO

BACKGROUND: Inactivated Polio Vaccine (IPV) campaign was conducted in February 2019 in Karachi where needle-free injectors were introduced for the administration of the fractional dose of IPV (fIPV) on a large scale. This study aimed to determine the impact of needle-free injectors on vaccination coverage. METHODS: In four towns of Karachi, fIPV was given using needle-free injectors "PharmaJet Tropis ID". Whereas, in six towns full dose of IPV was administered to children of 4-59 months of age. Cluster surveys through rapid convenience assessment method were conducted after the completion of vaccination activity. RESULTS: A total of 33,815 households' data was analyzed. Among these, 27,650 (82.8%) children were vaccinated. In fIPV areas, 85.3% of children were vaccinated compared to 79.5% in full dose IPV areas. A comparison of reasons for unvaccinated showed that 1.6% of parents do not give importance to vaccination in fIPV areas compared to 4.2% in full IPV areas (p-value < 0.0001). More children were not vaccinated due to fear of injection 1.8% in full IPV areas compared to 0.7% in fIPV areas (p-value < 0.0001). The source of campaign information shows that more frequent mobile miking 3.1% was observed in fIPV areas compared to 0.4% in full IPV areas (p-value < 0.0001). CONCLUSIONS: Our analysis supports the fractional dose of IPV in mass campaigns to achieve good vaccination coverage especially using needle-free injectors "PharmaJet Tropis ID" and vigorous social mobilization activities are expedient in accomplishing high coverage.

RESUMO

Air pollution is associated with several severe physical, behavioral, and psychological health risks and glitches. Air pollution has been linked to 11 million premature deaths in Pakistan, out of the total 153 million premature deaths worldwide. Air pollution is continuously growing as a threatening challenge for Pakistan. Keeping this in view, the current study was designed to assess air pollution in terms of air quality index (AQI), particulate matters (PM2.5 and PM10), SO2, NO2, and O3 over six districts of Malakand division, Northern Pakistan. The second part of the study appraised the associated self-reported effects of air pollution on Pakistani students and the practices, perceptions, and awareness of the students regarding air pollution through a closed-ended questionnaire, administered to 4100 students. The first section of the questionnaire was focused on the physical effects associated with air pollution; the second section was focused on air pollution-linked behavior and psychology; the third portion was focused on perception and awareness of the subjects, whereas the final section was focused on practices and concerns of the subjects regarding air pollution. The students reported that exposure to air pollution significantly affected their physical health, behavior, and psychology. The subjects were aware of the different air pollutants and health complications associated with air pollution, and therefore had adopted preventive measures. It was concluded that air pollution had adverse impacts on the physical and psychological health of the respondents, which consequently altered their behavior. Mass awareness, proper mitigating plan, suitable management, and implementation of strict environmental laws are suggested before the air gets further polluted and becomes life-threatening.

RESUMO

OBJECTIVE: To evaluate the diagnostic accuracy of magnetic resonance imaging (MRI) in detection of intra-axial gliomas in suspected cases keeping histopathology as gold standard. METHODS: This cross-sectional study was conducted at Dow Institute of Radiology, DUHS from October 2017 - April 2018. Patients of either gender aged 30-70 years presenting with headache were included. Patients already diagnosed and referred for follow up were excluded. MRI was performed on 1.5T scanner by a trained MRI technician. T1, T2, FLAIR, diffusion weighted and T1 post contrast images were acquired and reviewed by two radiologists having more than five years post fellowship experience. Sensitivity, specificity, PPV, NPV and diagnostic accuracy of MRI for intraaxial gliomas was calculated taking histopathology findings as gold standard. RESULTS: Mean age of the patient`s was 51.71 ±10.85 years. Positive intraaxial gliomas on MRI were observed in 123 (79.90%) patients while on histopathology, positive intraaxial gliomas were observed in 131 (85.10%) patients. Diagnostic accuracy of MRI in detection of intra-axial gliomas taking histopathology findings as gold standard showed sensitivity, specificity, positive predicted value (PPV), negative predicted value (NPV) and overall diagnostic accuracy as 89.31%, 73.91%, 95.12%, 54.84% and 87.01%. CONCLUSIONS: MRI has high sensitivity, moderate specificity and high diagnostic accuracy in detection of intraaxial gliomas.

RESUMO

BACKGROUND & OBJECTIVE: Radiology has played a significant role in the diagnosis and quantifying the severity of COVID 19 pulmonary disease. This study was conducted to assess patterns and severity of COVID-19 pulmonary disease based on radiological imaging. METHODS: A prospective observational study was conducted in a large tertiary care public sector teaching hospital of Karachi, Pakistan from June 2020 till August 2020. All confirmed and suspected COVID-19 patients referred for chest X-rays and computed tomography (CT) scans were evaluated along with RT-PCR results. Suspected patients were followed for RT-PCR. Radiological features and severity of imaging studies were determined. RESULTS: Of 533 patients in whom X-rays were performed, majority had severe/critical findings, i.e., 304 (57.03%). Of 97 patients in whom CT scan was performed, mild/moderate findings were observed in 63 (64.94%) patients. Of 472 patients with abnormal X-rays, majority presented with alveolar pattern 459 (97.2%), bilateral lung involvement 453 (89.6%), and consolidation 356 (75.4%). Moreover, lobar predominance showed lower zone preponderance in 446 (94.5%) patients. Of 88 patients with abnormal CT findings, ground-glass opacity (GGO) 87 (98.9%) and crazy paving 69 (78.4%) were the most common findings. An insignificantly higher association of PCR positive cases was observed with severe/critical X-rays (p-value 0.076) and CT scan findings (p-value 0.431). CONCLUSION: Most common patterns on CT scans were GGO and crazy paving. While on chest radiographs, bilateral lung involvement with alveolar pattern and consolidation were most common findings. On X-rays, majority had severe/critical whereas CT scan had mild/moderate findings.

RESUMO

Diffuse idiopathic skeletal hyperostosis (DISH), being an asymptomatic condition, is generally discovered incidentally on imaging and it has not received much attention for research on clinical grounds. We assessed the prevalence of DISH, its associated factors, and interobserver agreement for computed tomography (CT)-based diagnosis of DISH. CT scans of chest, abdomen, and pelvis performed for various clinical indications were retrospectively reviewed. Resnick criteria were used for the diagnosis of DISH. Moreover, enthesopathy along with comorbidities was assessed. CT scans were observed by 3 observers having different experience levels. Out of total 416 patients, the prevalence of DISH was 30.8%. Strong positive agreement was observed between observer 1 and 2 (k = 0.89), observer 1 and 3 (k = 0.91), and observer 2 and 3 (k = 0.94). Reporting rate of DISH was 59.3%. Regression analyses showed that enthesopathy was 2.45 times (adjusted odds ratio [AOR]: 2.45, 95% confidence intervals [CI]: 1.48-4.05), diabetic patients were 4.74 times (AOR: 4.74, 95% CI: 2.89-7.78) while hypertensive patients were 2.17 times (AOR: 2.17, 95% CI: 1.30-3.62) more likely to have DISH in comparison to those who do not have DISH. A high prevalence of DISH was observed in our cohort. Enthesopathy and comorbidities like diabetes and hypertension were significant factors associated with DISH. Moreover, excellent agreement was observed in defining DISH on CT according to Resnick criteria.

RESUMO

OBJECTIVE: To evaluate the diagnostic accuracy of ultrasound in obstructive jaundice taking MRCP as gold standard. METHODS: This cross-sectional study was conducted at Dow Institute of Radiology (DIR), Dow University of Health Sciences (DUHS), Karachi from 2nd May 2018 till 2nd November 2018. Both male and female patients aged 30 to 80 years with suspected obstructive jaundice were included. Patients already diagnosed with obstructive jaundice were excluded. MRCP and ultrasound were performed in suspected patients. Diagnostic accuracy including sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of obstructive jaundice were calculated using contingency tables using MRCP findings as gold standard. RESULTS: Mean age of the patients was 54.73 ± 12.65 years. In causes of obstruction, choledocholothiasis was responsible for 85 (35.1%), stricture 61 (25.2%), carcinoma of head of pancreas 39 (16.1%), periampullary carcinoma 21 (8.7%), cholangiocarcinoma 10 (4.1%) and gallbladder carcinoma 26 (10.7%) of the cases. Diagnostic accuracy of ultrasound in obstructive jaundice taking MRCP findings as gold standard showed sensitivity, specificity, positive predicted value (PPV), negative predicted value (NPV) and overall diagnostic accuracy as 84.57%, 79.10%, 91.36%, 66.25% and 83.06%. CONCLUSION: Ultrasound has a high sensitivity, moderate specificity, and high diagnostic accuracy in diagnosis of obstructive jaundice.

RESUMO

Neuroendocrine tumours are a rare tumour type involving neuroectodermal cells. They are also termed carcinoids. Gastroenteropancreatic system is most commonly involved. They are classified as low, intermediate or high grade depending upon mitotic index and Ki-67 index. Their diagnosis involves measurement of chromogranin A levels. Ultrasound is the initial imaging modality for their evaluation. Endoscopic ultrasound allows close evaluation of the tumour. Staging is commonly undertaken by computed tomography scan. These tumours typically show hyper-enhancement on arterial phase. Their metastasis to the liver also shows arterial enhancement. Small bowel carcinoids tend to have hepatic and mesenteric spread. Mesenteric spread of disease gives a characteristic spoke wheel appearance. On magnetic resonance imaging, these tumours typically appear as hypointense on T1 weighted image, hyperintense on T2 weighted image and show avid enhancement on postcontrast scan. Surgical resection is appropriate treatment with follow-up at 6-month intervals during the first year. The current review was planned to cover the aetiology, diagnosis, staging, imaging techniques, imaging features and treatment of these rare tumours that need prompt diagnosis.

RESUMO

This study was conducted to determine the diagnostic accuracy of CT-guided core needle biopsy (CNB) using coaxial technique of pulmonary lesions, its complications and factors affecting them. A total of 122 patients with suspected lung malignancy underwent CT-guided CNB. Final diagnosis was confirmed by histopathology. There were 84 (89.4%) true positive while 26 (92.9%) true negative cases. Diagnostic accuracy, sensitivity, specificity, PPV, NPV, and overall diagnostic accuracy were 97.67%, 72.22%, 89.36%, 92.86% and 90.16% respectively. Pneumothorax was the only complication observed in 10 (8.2%) patients. The odds of pneumothorax was found to be 10.72 times higher among patients with 2.5cm of size of lesions (AOR 10.72, 95% CI 1.49-76.77) while 86% lower among patients having prone position (AOR 0.14, 95% CI 0.021-0.96). Results indicate that percutaneous CT guided biopsy of pulmonary lesions using coaxial technique is a safe procedure with a high diagnostic accuracy and lesser risk of major complications.

RESUMO

OBJECTIVE: To determine the relationship of tumor thickness of oral lesions with metastasis in neck based on CT scan. METHODS: A total of 58 oral squamous cell carcinoma patients having the median age of 46 (39-55) years. with either gender presented with malignant tumor of buccal mucosa and tongue were prospectively enrolled. A CT Scan with contrast was performed on all patients. Correlation of tumor thickness level with metastasis in neck was calculated using spearman's rank correlation coefficient test. RESULTS: Median age of the patients was 46 (39-55) years with preponderance of male gender, i.e. 48 (82.8%). Strong positive significant correlation was observed in between transverse dimension (TS) tumor size and stages of tumor (rho 0.673, p-value <0.001), Anterioposterior (AP) tumor size and stages of tumor (rho 0.675, p-value <0.001), and Craniocaudal (CC) tumor size and stages of tumor (rho 0.771, p-value <0.001). CONCLUSION: CT scan of neck with contrast can be used for predicting the positive presence of lymph node in neck with primary tumors having a size of more than 4 mm.

RESUMO

BACKGROUND: Hernioplasty for Inguinal hernia is one of the commonest operations performed in general surgical wards. More recently, interest has waxed and waned regarding the minimally invasive approach to hernioplasty. This study was carried out to assess the management outcome of minimally invasive hernioplasty (Totally extra-peritoneal approach) as the treatment of choice for uncomplicated (incomplete and reducible) inguinal hernia. METHODS: In this quasi experimental study patients aged between 14-83 years who were otherwise fit and willing for total extra-peritoneal laparoscopic repair were recruited prospectively over a 10 month period. Thirty-seven such patients were operated and followed up in the hernia clinics. Six cases were later excluded for lack of proper follow-up. RESULTS: The typical patient was middle-aged male with right-sided inguinal hernia. Mean operating time was 53.3 minutes. No conversion was undertaken; however, there was one case of small bowel injury that went unrecognized on-table but necessitated subsequent laparotomy. Overall morbidity was 13.5%. Mean length of hospitalization was 2.89 days. Mean duration to normal routine life was 9.25 days. Overall, 70.9% of patients expressed satisfaction with the surgery. CONCLUSION: Totally extra-peritoneal mesh repair is a new and safe technique for hernioplasty with acceptable rates of morbidity and it is procedure of choice for recurrent and bilateral inguinal hernias and also used as alternate to open hernioplasty for uncomplicated (incomplete and reducible) inguinal herma.

RESUMO

Mongolian spots are bluish-grey, irregular, hyperpigmented macules present at birth or that appear in the first few weeks of life. They are classified as atypical if they occur in unusual locations without spontaneous disappearance after infancy; or if new lesions continue to appear beyond early infancy. Although they are generally considered benign, recent studies have shown that atypical Mongolian spots may be associated with inborn errors of metabolism, such as lysosomal storage disorders and neurocristopathies. An 11-month-old male presented with multiple aberrant Mongolian spots on the abdomen, back, buttocks, arms, and legs, with the largest patch measuring 10x10 cm. Additionally, the child exhibited coarse facial features, a high-arched palate, low-set ears, and a depressed nasal bridge. Systemic examination revealed hepatosplenomegaly, fundus examination showed a hazy cornea, and the urine glycosaminoglycan test was positive, prompting us to conduct further research prioritising lysosomal storage disorders. The mucopolysaccharidosis (MPS) spot test was positive, and electrophoresis for MPS revealed bands for chondroitin sulfate and dermatan sulfate, confirming the diagnosis of MPS. Enzyme assay revealed no alpha-iduronidase activity and normal beta-galactosidase activity, thus confirming Hurler's disease. This case report highlights the importance of considering atypical Mongolian spots as a potential indicator of underlying storage disorders, enabling early intervention.

RESUMO

BACKGROUND: Animal reproduction performance is crucial in husbandry. Immunocastrated animals serve as an ideal animal model for studying testicular function. During androgen suppression, the testis undergoes dramatic developmental and structural changes, including the inhibition of hormone secretion and spermatogenesis. METHODS: To characterize this process, we investigated the effects of castration using a recombinant B2L and KISS1 DNA vaccine, and then identified functional genes in the testes of Yiling goats using RNA-seq and WGS. The experimental animals were divided into three groups: the PVAX-asd group (control), PBK-asd-immunized group, and surgically castrated group. RESULTS: The results demonstrated that the administration of the recombinant PBK-asd vaccine in goats elicited a significant antibody response, and reduced serum follicle-stimulating hormone (FSH) and luteinizing hormone (LH), resulting in smaller scrotal circumferences and decreased sexual desire compared to the control group. In addition, RNA transcriptome sequencing (RNA-seq) analysis of the testes revealed that the biological processes after immunocastration mainly focused on the regulation of cell matrix adhesion, histone acetylation, negative regulation of developmental processes, apoptosis, and activation of the complement system and the thrombin cascade reaction system. Then, we integrated the whole-genome sequencing and testis transcriptome, and identified several candidate genes (FGF9, FST, KIT, TH, TCP1, PLEKHA1, TMEM119, ESR1, TIPARP, LEP) that influence steroidogenesis secretion and spermatogenesis. CONCLUSIONS: Multiple pathways and polygenic co-expression participate in the response to castration vaccines, altering hormone secretion and spermatogenesis. Taken together, our atlas of the immunocastration goat testis provides multiple insights into the developmental changes and key factors accompanying androgen suppression, and thus may contribute to understanding the genetic mechanism of testis function. Joint analysis of whole genome sequencing and RNA-seq enables reliable screening of candidate genes, benefiting future genome-assisted breeding of goats.

RESUMO

Objective: To determine the role of the serial portable chest X-ray in the diagnosis and quantification of patients with confirmed COVID-19 admitted to a tertiary care hospital. Methods: A retrospective study was conducted at Dow Institute of Radiology, Dow University of Health Sciences. Confirmed positive cases of COVID-19 from November 2020 to January 2021 were retrospectively studied. Patients' demographics and clinical characteristics, chest X-ray findings, and outcomes were retrieved through electronic medical records. Baseline and final follow-up chest X-rays findings were compared by using chest X-ray severity score. Multivariable logistic regression was used to evaluate the relationship between patients' characteristics and patient outcomes. Results: The study included 329 patients with a mean age of 56.43 ± 13.10 years (range 16-85 years). Peripheral consolidation and ground glass opacities (89.4%) were the most common X-ray findings followed by bilateral lung involvement (79.0%) and perihilar consolidation/ground glass opacities (69.9%). Among the patients who were admitted, 61.4% were discharged, 49.5% had prolonged length of stay ≥10 days, and 37.7% died. After adjustment of all patients' characteristics, the multivariate model showed no significant difference in chest X-ray severity score in relation to the patient's outcome. Patients who were admitted to the intensive care unit, and received oxygen support, bilevel positive airway pressure, and a ventilator were significantly associated with the outcome of being discharged, prolonged hospital stay, and death. Conclusion: Peripheral consolidation and ground glass opacities were the most common chest X-ray findings in admitted COVID-19 patients. No significant difference in chest X-ray severity score was noted in the primary outcome of being discharged, prolonged hospital stay, and death. There is no requirement for daily chest X-rays in hospitalized patients until required in the condition of worsening symptoms or significant intervention such as endotracheal intubation.

RESUMO

Motorbike spoke wheel injuries (SWIs) among children are a notable public health concern, especially in low and middle-income regions. The primary objective of this study is to comprehensively examine the patterns of motorbike spoke wheel injuries (SWIs) in children. Additionally, the study introduces a novel classification system for these injuries. The implementation of this classification system aims to streamline the management of SWIs, making it more efficient and facilitating the development of standardized treatment protocols. This prospective observational study was conducted in the Accident and Emergency Department from January 2019 to 2021. Children < 14 years of age of either gender with foot and ankle injury due to motorbike spoke wheels as passengers and presenting within 3 days were included. The motorbike SWI was assessed for its location and classified by a new classification as Class I, Soft tissue injury without skin loss; Class II, Skin loss of more than 1 cm without underlying tissue involvement; Class III, Skin loss with underlying tissue involvement, this class is further divided on basis of underlying soft-tissue involvement; Class IV: mangled foot/toe. Management plan and outcome were noted. In our study158 children suffering from SWI were registered with a mean age of 6.2 ± 5.4 years, 127 (80.37%) males and 31 (19.62%) females. Class I injury was seen in 18 (11.39%) patients, class II in 69 (43.67%), and class III in 68 (43.03%) patients. Class III injuries were further subcategorized as follows: IIIT (Tendon) injuries, which accounted for 32 cases (20.25%); IIIB (Bone) injuries, with 29 cases (18.35%); and IIINV (Neurovascular) injuries, identified in 7 cases (4.43%). Class IV injuries were observed in 3 (1.8%) children. The flap was needed in 33 (20.88%) patients. There were no complications like flap necrosis or graft rejection. In this current study, a new classification system specific for a motorbike SWI has been introduced along with its application on children presenting at tertiary care hospital's emergency department. The application of the proposed classification will enable universal management guidelines for SWIs, especially in the Ino-Pak region where SWIs are common.

RESUMO

Objective: Increasing rates of antimicrobial resistance among E. coli is a growing concern worldwide. We aimed to assess the changing antibiotic sensitivity pattern in Uropathogenic E. coli over a period of 12 years with special emphasis on ESBL-producing E. coli. Methods: A retrospective study was done on the population of Islamabad from 1st Jan 2005 to Dec 2010 and then continued from 1st Jan 2016 to 31st May 2021. A total of 12000 samples were analyzed for isolation and identification of bacteria and antimicrobial susceptibility testing, from patients having uncomplicated urinary tract infections. Our primary was to find the antibiotics with the highest sensitivity against E. Coli in 2021, while our secondary outcome was to find the overall sensitivity pattern of E. Coli to antibiotics from 2005 to 2021. Results: There was a decrease in susceptibility rates of E. coli to Amoxicillin-Clavulanic Acid 47%, Trimethoprim-Sulfamethoxazole (TMP-SMX) 27%, Fluoroquinolones 24% & Cephalosporins 38%. There was a significant increase in the use of Nitrofurantoin and Fosfomycin. High resistance rates to Fluoroquinolones (76%), TMP-SMX (73%), Cephalosporins (62%), and Amoxicillin (53%) were documented. However, significantly high degree of sensitivity rates to Fosfomycin (92%), Aminoglycosides (90%) & Nitrofurantoin (80%) were recorded. Conclusions: Uropathogenic E. coli shows the highest sensitivity to Fosfomycin and Aminoglycosides in the year 2021, followed by Nitrofurantoin and Sulbactam. Cephalosporins, Amoxicillin/Cluvalanic acid, TMP-SMX, and Fluoroquinolones show a declining sensitivity pattern. UTIs can be prevented well by lifestyle changes, taking vitamins, trace elements, and carbohydrates.

RESUMO

OBJECTIVE: To determine the coagulation abnormalities and relationship between abnormal clotting tests and the risk of gastrointestinal bleeding (GI) among chronic liver disease (CLD) patients admitted at a tertiary care hospital in Pakistan. METHODS: Adult CLD patients admitted at Liaquat University Hospital Jamshoro, during Nov 2004-Oct 2005, were included in the study. The patients blood were tested for coagulation abnormalities including prothrombin time (PT), activated partial thromboplastin time (aPTT), platelet count and plasma fibrinogen. Association was seen between the abnormal clotting tests and the gastrointestinal bleeding by calculating relative risk (RR) with 95% confidence interval. RESULTS: PT was prolonged in 88% and aPTT was raised in 71% cases of CLD. Both PT and aPTT were prolonged in 67% CLD cases. Approximately 37% CLD cases had decreased platelet count and 15% cases had decreased serum fibrinogen level. Relative risk of GI bleeding with abnormal clotting tests in CLD cases were weakly positive for PT (RR = 1.02; 95% CI, 0.49-2.10), negative for aPTT (RR = 0.83; 95% CI, 0.47-1.45), strongly positive for decreased platelet counts (RR = 1.96; 95% CI, 1.08-3.56) and also for decreased fibrinogen level (RR = 1.47; 95% CI, 0.64-3.35). CONCLUSION: Coagulation abnormalities were profound in CLD. Decrease platelet counts and fibrinogen levels were related with GI bleeding but PT and aPTT were not significantly related with GI bleeding in patients with chronic liver disease. Nevertheless, these parameters (PT and aPTT) were still used as prognostic markers.

RESUMO

Introduction Acute appendicitis (AA) is the most common cause of acute abdomen in young adults. The diagnosis is usually made on various clinical findings. However, a missed case of acute appendicitis is a catastrophe as it later presents with life-threatening complications and results in medicolegal issues. Raised total leukocyte count (TLC) is a frequent finding in patients with acute appendicitis. As a convention, a normal leukocyte count usually rules out the differential diagnosis of acute appendicitis. Recent studies claimed that a substantial proportion of patients with normal TLC also had acute appendicitis and warranted a careful evaluation of such cases before sending them home. However, the reported frequency of acute appendicitis among TLC normal patients varied greatly among studies which necessitated the present study. Aim Our aim was to determine the frequency of acute appendicitis in patients of normal TLC. Materials and methods This descriptive cross-sectional study was conducted at the Department of Surgery, KRL Hospital Islamabad. This study was carried out from 1 July 2019 to 31 December 2019. This study involved 238 patients of both genders aged between 12 and 70 years suspected of acute appendicitis on physical and ultrasound findings but with a normal TLC (4,500-11,000 WBCs/µL). The outcome variable was the frequency of acute appendicitis among such patients which was diagnosed upon surgery (inflamed appendix with free fluid) and histopathology of excised tissue (mucosal inflammation, neutrophil infiltrates, wall necrosis). Frequency of acute appendicitis was compared across various age and gender groups. Written informed consent was obtained from every patient. Results The mean age of the patients was 27.4±15.5 years. Majority (n = 167, 70.2%) of the patients were aged ≤25 years, followed by 40 (16.8%) patients aged ≥46 years and 31 (13.0%) patients aged between 26 and 45 years. There were 135 (56.7%) male and 103 (43.3%) female patients with a male to female ratio of 1.3:1. All of the patients (100.0%) had pain in the right iliac fossa (RIF) while rebound tenderness, anorexia, nausea/vomiting, fever and dysuria were noted in 83.6%, 79.0%, 73.9%, 63.9% and 15.1% patients, respectively. The diagnosis of acute appendicitis was made in 198 (83.2%) patients with normal TLC and suspicion of acute appendicitis on physical findings and ultrasound. When stratified, there was no statistically significant difference in the frequency of acute appendicitis across various age (p-value = 0.988) and gender (p-value = 0.913) groups. Conclusion In the present study, contrary to the routine impression that normal TLC rules out the differential diagnosis of acute appendicitis, a substantial proportion of patients with clinical and ultrasound suspicion of acute appendicitis but normal TLC had acute appendicitis which is worrisome as a missed case may later present with complications. The present study thus warrants cautious evaluation of clinically suspected cases with normal TLC count to avoid a missed appendicitis and improve the outcome in future surgical practice.
