Hyponatremia is an expected electrolyte resultant in diabetic ketoacidosis (DKA) that presents secondary to the dilutional effect of hyperglycemia. However, hypernatremia in DKA is a rare presentation, more common in the pediatric population, that rides poor morbidity and mortality. We describe three cases of patients presenting with DKA and hypernatremia with altered sensorium and share details on pathophysiology and treatment that expand our understanding amongst clinicians.
Background: A pyogenic liver abscess (PLA) is the most frequently observed subtype of liver abscess in the western world. The disease has been subjected to a remarkable change. We aimed to investigate the recent trend in pyogenic liver abscess's epidemiology, clinical, microbiological, and risk factors features. Methods: A retrospective analysis of medical records was done for the patients diagnosed with PLA from January 2000 to June 2018. The institutional review board approved the study. Results: We identified 113 patients with PLA, 60% were males, with a mean age of 54 ± 20 years, and 58 ± 19 years old for males and females, respectively (p = 0.298), with an increasing annual incidence in 2012-2013, and 2016-2017 (Figure 1). Fever and right upper quadrant abdominal pain were the most common symptoms (65%, 55%, respectively). Forty percent of the patients had Biliary tract diseases like cholecystitis or biliary intervention as cholecystectomy or ERCP, and 20% had diabetes mellitus (Table 1). The abscess culture was obtained in 96 cases, 37 cases were negative (39%), 27 cases showed polymicrobial growth (28%) and 15 cases showed Escherichia coli (16%) (Figure 2). The abscess cultures were mostly negative in the first 5 years, then changed to Streptococcus anginosus, and polymicrobial growth in the last four years. Conclusions: PLA is more common in males with a recent increase in incidence. Culture negative PLA was observed in patients who were empirically treated with antibiotics. Polymicrobial was the most common identifiable organism with a change in the microbiological trend every 5 years.
Hybrid argon plasma coagulation (HybridAPC® [HAPC]) is an evolution of the standard argon plasma coagulation (APC) technology, where the application of APC is preceded by highpressure needleless submucosal injection. APC is indicated for the ablation of benign and dysplastic mucosal lesions, such as vascular malformations or Barrett's mucosa. HAPC offers safety and efficacy advantages over standard APC because the submucosal injection acts as a heat sink that disperses energy. This ensures that the underlying muscularis propria remains unaffected, and only the mucosal layer is coagulated in its entirety. An 81-year-old Hispanic male was found to have a 1.2-cm mucosal nodule along the incisura of the stomach. Pathology of the biopsy specimen revealed high-grade dysplasia, and he subsequently underwent endoscopic ultrasound examination, which confirmed the presence of an isolated gastric nodule with no deep invasion of the muscularis propria, consistent with a uT1N0Mx endosonographic staging. He then underwent endoscopic submucosal dissection of the lesion. Pathology of the excised specimen confirmed the presence of multifocal high-grade dysplasia, arising in the background of extensive intestinal metaplasia. The deep margin was clear; however, the lateral resection margins showed focal involvement of intestinal metaplasia with low-grade dysplasia. Surveillance endoscopy confirmed the persistence of diffuse intestinal metaplasia. He was then treated with widespread HAPC due to the presence of underlying diffuse intestinal metaplasia in the stomach. HAPC is an effective and efficient treatment modality for mucosal lesions. In one series of 50 patients, 96% achieved complete macroscopic remission of Barrett's mucosa after a median of 3.5 APC sessions, and 85% achieved complete histological remission. HAPC is a promising therapeutic modality as a thermal injury is targeted, and the depth of injury is contained. This provides immediate procedural efficacy and safety benefits, and reduces subsequent complications when compared with standard APC. We anticipate that the applications of HAPC will continue to grow, as this modality is adopted into common procedural parlance. This case appears to be the first to describe the use of HAPC for definitive treatment of diffuse intestinal metaplasia.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
