Serum creatinine abnormality emerged on the same day, which improved gradually without any specific intervention. Paraquat poisoning can cause silent acute renal impairment. Abundant fluid resuscitation after renal impairment is not essential provided that sufficient fluid is administered beforehand. Repeated screening for renal impairment and sufficient fluid resuscitation are important in the early phase of low-dose paraquat poisoning.","PeriodicalId":400314,"journal":{"name":"Case Reports in Acute Medicine","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121328118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As children’s bones are not fully developed, the risk of bladder injury by external force is greater in children than adults. Pelvic fractures often cause the bladder to rupture, as do strong external forces when the bladder is filled. Bladder rupture is categorized as extraperitoneal or intraperitoneal, and treatments differ between the two. Extraperitoneal injury usually heals after drainage alone, whereas intraperitoneal injury usually requires surgical intervention such as a combination of surgical repairs and drainage. Herein, we report a pediatric case of intraperitoneal bladder rupture successfully treated without surgical repair (i.e., with drainage via an intraperitoneal tube and a urethral catheter only). Our report suggests that nonoperative treatment is an option for pediatric patients with intraperitoneal bladder rupture if certain conditions are met.","PeriodicalId":400314,"journal":{"name":"Case Reports in Acute Medicine","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115405264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because metformin is effectively removed by renal replacement therapy, early initiation of hemodialysis is crucial for metformin overdose. We report a case of a 38-year-old male who was brought to our emergency department (ED) with altered mental status. He subsequently developed severe lactic acidosis with a peak lactate level of 33.4 mmol/L. No clear etiology was identified for these critical conditions at the ED. Although metformin intoxication could not be confirmed at this time, we decided to start hemodialysis immediately. Soon after hemodialysis, blood pH and lactate levels dramatically improved. The patient fully recovered after 9 days of intensive care unit (ICU) stay. Later on, his serum metformin concentration was revealed to be 146 μg/mL and 26 μg/mL at ICU admission and after dialysis at day 3, respectively (therapeutic range, 1–2 μg/mL). Early initiation of hemodialysis might be beneficial for diabetic patients with unexplained severe lactic acidosis despite uncertainties in history of overdose or serum concentration of metformin.","PeriodicalId":400314,"journal":{"name":"Case Reports in Acute Medicine","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132264753","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are only a few published cases of tracheal disruption from invasive lymphoma, and most of the patients did not survive. Tumor erosion and nodal necrosis from rapid tumor growth or chemotherapeutic response can cause tracheal disruption. We report here a case of tracheal perforation after chemotherapy of lymphoma. A 69-year-old Thai man presented with upper airway obstruction from a large neck mass encasing and invading the trachea. The patient was intubated to bypass the tracheal obstruction. Biopsy of the mass showed diffuse large B-cell lymphoma. Chemotherapy was urgently administered. Two days after treatment, the patient developed acute respiratory distress with high airway resistance. Emergency bronchoscopy and chest computerized tomography revealed disrupted anterior wall of trachea and endotracheal tube displacement, which created a false track into the mass. Tumor necrosis was thought to be the cause of this perforation and tube malposition. The tube was repositioned by bronchoscopic guidance. Unfortunately, the disrupted trachea could not be reconstructed. Palliative care was consequently provided, and the patient finally passed away a week after the catastrophic event. This report demonstrates clinical presentation, chest imaging, and bronchoscopic findings of tracheal perforation, which is a rare complication following the treatment of lymphoma.","PeriodicalId":400314,"journal":{"name":"Case Reports in Acute Medicine","volume":"175 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121224643","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
