Parecoxib Vs Paracetamol for Treatment of Acute Renal Colic Due to Ureteric Calculi: A Randomized Controlled Trial.

OBJECTIVE: To compare efficacy and safety of parecoxib and paracetamol for treatment of acute renal colic due to ureteric stones. MATERIALS AND METHODS: A randomized, double blinded, controlled trial included adult patients presented to emergency department with acute renal colic due to ureteric calculi between June 2019 and August 2020. Patients with hypersensitivity to either drug, peptic ulcer, coronary ischemia, peripheral vascular or cerebrovascular disease, hepatic impairment (Child-Pugh score >10) or chronic kidney disease stage 4 or 5 were excluded. Eligible patients were randomized to group 1 who received 1g intravenous Paracetamol infusion or group 2 who received 40mg intravenous Parecoxib infusion. Pain analogue score was evaluated before treatment and 30 minutes afterwards. The primary endpoint was the need for rescue analgesia for persistent pain. Safety was evaluated by the incidence of adverse events. RESULTS: The study included 203 patients (102 in group 1 and 101 in group 2). Pretreatment patients' data were comparable for both groups. The mean pain analogue score decrease from 7.6 to 3.8 in paracetamol group (P <.001) and from 7.8 to 3.4 in parecoxib group (P <.001). Rescue analgesia were needed in 36 patients (35.3%) in paracetamol group and 27 patients (26.7%) in parecoxib group (P = .187). Minor adverse events developed in 2 patients (2%) in paracetamol group and 3 patients (3%) in parecoxib group (P=0.683). CONCLUSION: Paracetamol and Parecoxib were effective for treatment for patient with acute renal colic. Both treatments showed comparable results in reduction of pain and need for rescue analgesia with minimal adverse events.

Detection of SARs-CoV-2 in wastewater using the existing environmental surveillance network: A potential supplementary system for monitoring COVID-19 transmission.

The ongoing COVID-19 pandemic is caused by SARs-CoV-2. The virus is transmitted from person to person through droplet infections i.e. when infected person is in close contact with another person. In January 2020, first report of detection of SARS-CoV-2 in faeces, has made it clear that human wastewater might contain this virus. This may illustrate the probability of environmentally facilitated transmission, mainly the sewage, however, environmental conditions that could facilitate faecal oral transmission is not yet clear. We used existing Pakistan polio environment surveillance network to investigate presence of SARs-CoV-2 using three commercially available kits and E-Gene detection published assay for surety and confirmatory of positivity. A Two-phase separation method is used for sample clarification and concentration. An additional high-speed centrifugation (14000Xg for 30 min) step was introduced, prior RNA extraction, to increase viral RNA yield resulting a decrease in Cq value. A total of 78 wastewater samples collected from 38 districts across Pakistan, 74 wastewater samples from existing polio environment surveillance sites, 3 from drains of COVID-19 infected areas and 1 from COVID 19 quarantine center drainage, were tested for presence of SARs-CoV-2. 21 wastewater samples (27%) from 13 districts turned to be positive on RT-qPCR. SARs-COV-2 RNA positive samples from areas with COVID 19 patients and quarantine center strengthen the findings and use of wastewater surveillance in future. Furthermore, sequence data of partial ORF 1a generated from COVID 19 patient quarantine center drainage sample also reinforce our findings that SARs-CoV-2 can be detected in wastewater. This study finding indicates that SARs-CoV-2 detection through wastewater surveillance has an epidemiologic potential that can be used as supplementary system to monitor viral tracking and circulation in cities with lower COVID-19 testing capacity or heavily populated areas where door-to-door tracing may not be possible. However, attention is needed on virus concentration and detection assay to increase the sensitivity. Development of highly sensitive assay will be an indicator for virus monitoring and to provide early warning signs.

Right Testicular Infarction Secondary to Spontaneous Testicular Vein Thrombosis in a Child: Case Report and Literature Review.

OBJECTIVES: To describe a case of right testicular vein thrombosis in a child and to review the literature describing similar cases and their management. METHODS: An extensive literature review of the English language literature was conducted using the following databases: PubMed, ScienceDirect and Google Scholar. RESULTS: Six cases were reported previously and summarized in this article. CONCLUSION: A 14-year-old boy who suffered from spontaneous right testicular vein thrombosis was treated with right orchiectomy and oral anticoagulation. We also reviewed and summarized the previously described cases of pediatric testicular vein thrombosis.

Gall stone ileus: Unfamiliar cause of bowel obstruction. Case report and literature review.

INTRODUCTION: Gallstone ileus is a rare sequela of cholelithiasis. The pathology occurs as a result of bilioenteric fistula due to erosion by the offending gallbladder stone. It is most commonly encountered in elderly females and CT imaging is diagnostic in the majority of cases. Surgical intervention aims to promptly relief the obstruction by removing the gallstone and dealing with the fistula. Morbidity and mortality are usually high since it usually occurs in elderly patients. PRESENTATION OF CASE: An 88-year-old lady with multiple chronic medical problems and no history of biliary manifestation presented with acute small bowel obstruction. Abdominal CT imaging revealed a bilioenteric fistula and an impacted gallstone in the jejunum causing occlusion. Laparotomy was performed and the stone was removed via enterolithotomy. Manipulation of the cholecystoduodenal fistula was not attempted due to severe inflammatory adhesions. The patient had uneventiful postoperative course and remained symptom free on one year follow-up. DISCUSSION AND CONCLUSION: Management of gallstone ileus is mainly surgical. Delay in detection and treatment of gallstone ileus may result in significant morbidity and mortality. The choice of surgical option is influenced by the preoperative medical status of the patient. A literature review generally supports the employment of enterolithotomy in high-risk patients and reserving cholecystectomy and resection of the fistula for less comorbid patients with feasible anatomy.
