ABSTRACT

We report a patient with a mucocele with diffuse wall thickening diagnosed by transabdominal ultrasonography and contrast-enhanced ultrasonography. Transabdominal ultrasonography showed diffuse thickening of the entire appendix wall and an anechoic area that appeared to be fluid collected throughout the appendix lumen. However, the "onion skin sign" was not detected. Contrast-enhanced ultrasonography combined with superb microvascular imaging revealed abundant mucosal blood flow and no abnormal vascular network within the mucosa of the appendix wall. We preoperatively diagnosed a mucocele complicated by acute and chronic appendicitis, and ileocecal resection was performed. Macroscopic and microscopic findings of the resected specimens demonstrated that the appendiceal wall was diffusely thickened, with fibrosis and inflammatory cell infiltration, and that the appendiceal root rumen was narrowed with epithelial hyperplasia. No neoplastic changes were observed. The cause of the appendiceal mucocele was likely fibrosis and stenosis at the root of the appendix due to initial acute appendicitis.

ABSTRACT

BACKGROUND AND AIM: The clinical severity and course of acute lower gastrointestinal bleeding (ALGIB) are believed to differ between inpatient-onset and outpatient-onset cases, but no reports have investigated these issues in detail. We aimed to evaluate the clinical differences between inpatient-onset and outpatient-onset ALGIB. METHODS: Medical records of patients who had undergone emergency colonoscopy for ALGIB were retrospectively reviewed. The severity was evaluated using the NOBLADS score. Patients with obvious ALGIB relapse and/or persistent iron-deficiency anemia after emergency colonoscopy were considered to exhibit a poor clinical course. RESULTS: We reviewed 723 patients with ALGIB and divided them into the inpatient-onset cohort (172 patients) and outpatient-onset cohort (551 patients). Compared with the outpatient-onset cohort, the inpatient-onset cohort had a significantly higher proportion of patients with a poor clinical course (51.2% vs 21.6%; P < 0.001) and a significantly higher mean NOBLADS score (3.6 ± 1.1 vs 2.5 ± 1.0; P < 0.001). The most common bleeding source was acute hemorrhagic rectal ulcer (52.3%) in the inpatient-onset cohort and colonic diverticular bleeding (29.4%) in the outpatient-onset cohort. Multivariate analysis showed that a platelet count < 15 × 104 /µL and albumin concentration < 3 g/dL were significantly associated with a poor clinical course in the inpatient-onset cohort. CONCLUSIONS: The clinical course was significantly worse in the inpatient-onset cohort than in the outpatient-onset cohort. The bleeding source, clinical characteristics, and clinical course differed between the inpatient-onset and outpatient-onset cohorts. The clinical course in the inpatient-onset cohort may depend on the patient's condition at ALGIB onset.

ABSTRACT

Background: Herpes zoster (HZ) occurs mostly in elderly and immunocompromised individuals. Immune reconstitution may be associated with the pathogenesis of HZ. As immune checkpoint inhibitor (ICI) treatment amplifies the immune response, use of ICI may increase the incidence of HZ. There have been few studies of HZ in lung cancer patients treated with ICI. This study was performed to investigate the frequency of HZ in lung cancer patients who received ICI or cytotoxic chemotherapeutic agents. Methods: We searched the electronic medical records for lung cancer patients receiving anticancer drug therapy at our hospital, who developed HZ between April 2011 and June 2020. Results: The review identified 80 patients with a history of ICI treatment (ICI group) and 356 who had been treated with cytotoxic chemotherapeutic agents alone (non-ICI group). Among the 20 patients who developed HZ, 4 (5.0%) belonged to the ICI group and 16 (4.5%) to the non-ICI group (P=0.782). After exclusion of patients aged 65 years and older, to avoid effects of advanced age on the results, the ICI and non-ICI groups consisted of 24 and 81 patients, respectively. In total, 3 of the 24 patients (12.5%) in the ICI group and 1 of the 81 (1.2%) patients in the non-ICI group developed HZ (P=0.0365). Conclusions: There was no significant difference in the rate of HZ between lung cancer patients treated with ICI and those treated with cytotoxic chemotherapy alone. However, patients younger than 65 years treated with ICI might be at increased risk of HZ. Because this is a retrospective small study, further prospective observational studies are needed.

ABSTRACT

Glucocorticoid therapy is effective for treating autoimmune pancreatitis, but autoimmune pancreatitis itself and steroid therapy aggravate glycemic control. A 77-year-old man with type 2 diabetes was consulted due to aggravation of glycemic control. He was diagnosed with autoimmune pancreatitis. We promptly started glucocorticoid therapy for autoimmune pancreatitis and insulin therapy for glycemic control. Subsequently, both pancreatitis and diabetes were markedly ameliorated. After stopping glucocorticoid therapy, good glycemic control continued with diet therapy alone. Starting glucocorticoid therapy at an early stage of autoimmune pancreatitis is very important for preserving the insulin secretory capacity and improving glycemic control.
