RESUMO
BACKGROUND: Central nervous system involvement in chronic lymphocytic leukemia rarely occurs, and there is no standard therapy for central nervous system involvement in chronic lymphocytic leukemia. This article aims to analyze the diagnosis and treatment of central nervous system involvement in chronic lymphocytic leukemia. CASE PRESENTATION: It reports two cases of central nervous system involvement in chronic lymphocytic leukemia describing the clinical course, therapy, and prognosis. Case 1 is a 67-year-old Asian male patient, he experienced complications with central nervous system involvement after developing resistance to ibrutinib, bendamustine, and rituximab (BR) chemotherapies. The central nervous system lesion was controlled with high-dose methotrexate combined with pomalidomide, but Richter transformation occurred several months later. Case 2 is a 62-year-old Asian female patient, she had central nervous system involvement at initial diagnosis, and bone marrow and central nervous system lesions were controlled by ibrutinib therapy. CONCLUSION: Central nervous system involvement in chronic lymphocytic leukemia is rare and can be diagnosed on the basis of clinical features, cerebrospinal fluid testing, and radiographic evaluation. Ibrutinib, pomalidomide, and other drugs that can cross the blood-brain barrier may be effective for treating central nervous system involvement in chronic lymphocytic leukemia.

Postoperative adhesions are a common cause of adhesive small bowel obstruction (ASBO), and recognition of intestinal strangulation is important. The aim of this study is to analyze the clinical factors for strangulating obstruction and to identify the predictors for recurrence of ASBO.A retrospective study was conducted using the database in our department. Patients with ASBO from January 2013 to April 2016 were included in the study and were subject to follow-up. The clinical factors associated with strangulating obstruction and recurrence after treatment were analyzed by using univariate and multivariate logistic regression model.In total, 288 ASBO patients were included in the study. Of these, 37 (12.9%) patients had occurred strangulating obstructions, and 251 (87.1%) patients had simple obstructions. Four clinical parameters, including increasing heart rate (>100 bpm), increasing WBC count (>15â×â10/L), CT findings of thickening or swelling of the mesentery, and CT showing seroperitoneum were detected as independent clinical factors for intestinal strangulation. Eighty-four (29.2%) patients experienced recurrence of obstruction during the median 24 months of follow-up. Recurrence rates were reduced in patients who underwent surgical treatment compared with those who received conservative management [21.3% (26/122) vs 34.9% (58/166) (Pâ=â.010)]. Nevertheless, the recurrence rates were not significantly increased in patients with strangulating obstructions compared with those with simple ASBO [34.3% (12/35) vs 27.7% (72/253) (Pâ=â.186)].Four clinical parameters including tachycardia, leukocytosis, along with CT findings of thickening or swelling of the mesentery and CT showing seroperitoneum, associated with occurrence of intestinal strangulation in ASBO. ASBO patients who underwent surgical treatment had a reduced recurrence rate, but ASBO patients with strangulating obstructions had not increase the recurrence rates than those of patients with simple ASBO.

RATIONALE: Neonatal appendicitis is extremely rare, and preoperative diagnosis is challenging. This study aimed to investigate the utility of ultrasound for the diagnosis of neonatal appendicitis. PATIENT CONCERNS: Four cases of neonatal appendicitis were included in this case series. One was a female infant and the other 3 were male infants; they were aged from 10 to 17 days. DIAGNOSES: Neonatal appendicitis. INTERVENTIONS: Four newborns in our hospital were diagnosed with neonatal appendicitis by abdominal ultrasound. Their sonographic features were summarized and compared with surgical and pathological findings. OUTCOMES: In these infants, abdominal ultrasound demonstrated ileocecal bowel dilatation, intestinal and bowel wall thickening, and localized encapsulated effusion in the right lower quadrant and the abscess area, which was assumed to surround the appendix. LESSONS: Ultrasound is helpful for the diagnosis of neonatal appendicitis.
