RESUMEN
A 73-year-old man with a history of heterotaxy syndrome and intestinal malrotation developed hemorrhagic shock due to bleeding from a duodenal ulcer. Esophagogastroduodenoscopy failed to achieve hemostasis because of restriction of the view by massive hemorrhage. Transcatheter arterial embolization cannot achieve endovascular hemostasis due to the vascular anatomy. Therefore, surgical hemostasis was achieved. Intestinal malrotation due to heterotaxy syndrome is a risk factor for gastrointestinal bleeding. Severe gastrointestinal bleeding in patients with intestinal malrotation is difficult to control with endoscopy alone. Therefore, combined therapies with endoscopy, interventional radiology, surgical procedures, and intensive care are vital for achieving a better prognosis.
RESUMEN
Introduction Hypermucoviscous Klebsiella pneumoniae (hvKP) is related to invasive infections; however, there have been very few comprehensive reports on the clinical features and prognosis of critically ill patients with the infection. Methods We conducted a retrospective case series in a general intensive care unit in Japan. Patients with positive blood cultures for KP between January 1, 2020 and December 31, 2022 were included. hvKP was defined by the positivity in the string test. We analyzed the patient's characteristics at baseline, including comorbidities, abscess formation, Sequential Organ Failure Assessment (SOFA) score, Acute Physiology and Chronic Health Evaluation (APACHE) II score, septic shock, duration of hospitalization, 30-day mortality, and infection site. Results A total of 24 patients had a positive blood culture for KP; nine patients (37.5%) were positive for the string test (hvKP) while 15 (62.5%) were negative (non-hvKP). In both groups, the patients were old (mean age, hvKP 80.4 vs. non-hvKP 75.7 years) and more often male (five patients (55.6%) vs. 12 patients (80.0%)). No statistically significant difference was found between the two groups in terms of comorbidities, such as diabetes mellitus, chronic obstructive pulmonary disease, chronic kidney disease, and malignancy. No statistical difference was seen in abscess formation (two patients [22.2%] vs. one patient (6.7%)), SOFA score (5.2±4.8 vs. 4.7±3.4), APACHE II score (19.6 (15.0-20.0) vs. 17.0 (11.2-20.8)), septic shock (five patients (55.6%) vs. four patient (26.7%)), duration of hospitalization (37.2 (12.0-51.0) vs. 32.3 (9.5-21.0)), and 30-day mortality (two patients (22.2%) vs. two patients (13.3%)). Two cases with hvKP died within 24 h. No significant difference was seen in the infection sources; respiratory infection (2 (22.2%) vs. 1 (6.7%)), hepatobiliary infection (2 (22.2%) vs. 7 (46.7%)), and genitourinary infection (1 (11.1%) vs. 5 (33.3%)). Conclusions Critically ill patients with hvKP infection showed characteristics similar to those reported previously. However, the disease could rapidly become severe and have a poor prognostic outcome.
RESUMEN
A 78-year-old man with atherosclerosis was diagnosed with hepatocellular carcinoma by transfemoral angiography of the celiac and superior mesenteric arteries (SMA). After surgery, a serum examination revealed progressive renal failure with eosinophilia, leading to end-stage kidney disease, in addition to active gastric ulcers and pancreatitis. Cyanosis in the bilateral toes showed a cholesterol crystal embolism (CCE) in a skin biopsy. Autopsy revealed that CCE involved the arterioles of multiple organs, and its distribution was anatomically consistent with the vascular territories of the celiac artery and SMA. CCE should therefore be considered in patients presenting with multiple types of tissue damage in the vascular territories after angiography.
RESUMEN
Background: Coexistence of Takotsubo cardiomyopathy and psychogenic nonepileptic seizures has rarely been reported. Herein, we report a case of Takotsubo cardiomyopathy triggered by psychogenic nonepileptic seizures. Case Presentation: A 50-year-old woman with a 22-year history of dissociative and panic disorders and a 7-year history of seizures increasing in frequency was admitted due to cardiogenic shock. Based on the left ventriculography and electroencephalography findings, she was diagnosed with Takotsubo cardiomyopathy and psychogenic nonepileptic seizures. Seizures were controlled using antipsychotic agents, resulting in improved cardiac function, and she was discharged. However, she died of cardiopulmonary arrest 9 days after discharge. Conclusion: Since controlling psychogenic epileptic seizures is difficult, Takotsubo cardiomyopathy triggered by psychogenic nonepileptic seizures may have poor prognosis, requiring careful management and close monitoring.
RESUMEN
PURPOSE: Several D-amino acids have been shown to be protective against kidney injury in mice. Risperidone, a currently used atypical antipsychotic agent for schizophrenia, is also known to inhibit the activity of D-amino acid oxidase, which degrades certain D-amino acids. Based on the hypothesis that risperidone would prevent kidney disease progression, this study investigated the association between risperidone use and kidney function decline in patients with schizophrenia. METHODS: This retrospective cohort study included patients who were diagnosed with schizophrenia and had data available from two or more serum creatinine measurements between April 1, 2010, and March 31, 2020. Patients who used risperidone for at least 30 days were included in the risperidone group, whereas those who had no record of risperidone use were included in the control group. Cox regression models were used to evaluate the risk for 40% decline in estimated glomerular filtration rate (eGFR) in patients treated with risperidone compared to that in the control group. FINDINGS: Overall, 212 patients used risperidone and 1468 patients had no record of risperidone use. The mean age was 55 years, 759 (45%) of the patients were male, and the mean eGFR at baseline was 88 mL/min/1.73 m2. The mean age in the risperidone group was less than that in the control group (52 vs 56 years); other baseline characteristics were comparable between the two groups. During a mean follow-up of 1.6 years, 267 patients (16%) had a 40% eGFR decline. The incidence rate of 40% eGFR decline was lower in the risperidone group than in the control group (60 vs 104 per 1000 person-years). After adjustment for baseline age, sex, and eGFR, risperidone use was associated with a decreased risk for 40% eGFR decline (hazard ratio = 0.54; 95% CI, 0.33-0.87; P = 0.01). IMPLICATIONS: Risperidone use may be associated with decreased risk for kidney function decline in patients with schizophrenia. Further studies are warranted to validate these findings.
