Staphylococcus saprophyticus is a common pathogen of acute urinary tract infection (UTI) in young females. However, S. saprophyticus bacteremia originating from UTI is very rare and has not been reported in Korea. We report a case of S. saprophyticus bacteremia from UTI in a 60-year-old female with a urinary stone treated successfully with intravenous ciprofloxacin, and review the cases of S. saprophyticus bacteremia reported in the literature. Thus, the microorganism may cause invasive infection and should be considered when S. saprophyticus is isolated from blood cultures in patients with UTI.

Objective: To investigate the effects of dietary habits on general and abdominal obesity in community-dwelling patients with schizophrenia spectrum disorder according to sex. Methods: A total of 270 patients with schizophrenia spectrum disorder registered at mental health welfare centers and rehabilitation facilities were recruited. General obesity was defined as a body mass index ≥ 30 kg/m 2 , and abdominal obesity was defined as a waist circumstance ≥ 90 cm in men and ≥ 85 cm in women. Dietary habits were evaluated using dietary guidelines published by the Korean Ministry of Health and Welfare. Demographic and clinical characteristics along with dietary habits and information related to obesity were collected. Factors related to obesity were evaluated separately by sex. Results: Dietary habits differed according to sex, in that scores for healthy eating habits were lower in men than in women. In men, the prevalences of general and abdominal obesity were 17.0% and 37.3%, respectively. In women, the prevalences of general and abdominal obesity were 23.1% and 38.5%, respectively. Regression analysis showed that the scores of regular eating habits were negatively associated with general and abdominal obesity in men, and the scores of healthy eating habits were negatively associated with general and abdominal obesity in women. Conclusion Among patients with schizophrenia, regular eating habits might reduce the risk of obesity in men, and healthy eating habits might reduce the risk of obesity in women. Nutrition education should be provided to community-dwelling patients with schizophrenia to prevent obesity in this population.

Objective: This study investigated the effectiveness of switching to once-monthly long-acting injectable (LAI) aripiprazole from other second-generation antipsychotics including LAI paliperidone palmitate in both recent-onset and chronic schizophrenia patients. Methods: This was a 24-week prospective, open-label, flexible dose-switching study in patients with schizophrenia. Scores on the Positive and Negative Syndrome Scale (PANSS), Personal and Social Performance (PSP) scale, Clinical Global Impression (CGI), Subjective Well-being Under Neuroleptics−Short Form (SWN-K), and a computerized emotional recognition test (ERT) were evaluated. Subjects were divided into two groups (recent onset and chronic) based on 5 years’ duration of the illness. Results: Among the 82 patients participating, 67 (81.7%) completed the 24-week study. The discontinuation rate after switching to LAI aripiprazole did not differ according to clinical characteristics including type of previous antipsychotics. Scores on the PANSS, PSP, SWN-K, CGI, and ERT were significantly improved after a switch to LAI aripiprazole without exacerbation of metabolic parameters and bodyweight. The improvements in the PANSS, PSP, and CGI scores were significantly greater in patients with recent-onset than in those with chronic schizophrenia; the improvement in metabolic parameters was significantly greater in the latter group. Conclusion High rates of successful switching to LAI aripiprazole from other antipsychotics suggest its good tolerability and effectiveness. Improvements in psychopathology and social functioning were more evident in patients with recent-onset schizophrenia, and improvements in metabolic abnormalities were more prominent in patients with chronic schizophrenia.

Salmonella typhi infections usually manifest with high fever and gastrointestinal symptoms, however, occurrence of severe complications in other organs, such as pneumonitis, bronchitis, hepatitis, nephritis, encephalitis, and osteomyelitis, is possible. Although common surgical complications include ileal perforation and gastrointestinal haemorrhage, few cases of intussusception have been reported. Splenic infarction is another uncommon complication. In this report, we present a case of typhoid fever complicated with simultaneous small bowel intussusception and splenic infarction. A 27-year-old male patient with no previous history of interest underwent examination for fever, acute abdominal pain, and watery diarrhea of seven days duration. Findings on the initial examination indicated fever of 39.1degrees C, a distended abdomen with direct and rebound tenderness of diffuse localization, and rigidity. Abdominal computed tomography showed hepatomegaly, multiple lymphadenopathies, multiple segmental splenic infarctions, and small bowel ileus with intussusception, however, findings from the small bowel enema study showed spontaneous resolution of the intussusception. Despite antibiotic therapy, abdominal symptoms continued, therefore, the patient underwent exploratory laparotomy with suspicion of intestinal perforation. Surgical findings included multiple enlarged lymphadenopathies and coarse appearance of the liver, but no perforation was found. Results of the Widal test showed positivity for flagellar (H), somatic (O) and A antigens (1:640 dilutions each). Blood cultures showed Salmonella typhi. lymph nodes and biopsy showed mesenteric lymphadenitis, with enlarged lymph nodes due to distension of the sinusoids by macrophages, which showed erythrophagocytosis and tingible bodies. In addition, liver biopsy showed a granulomatous aggregate comprised of macrophages with an epithelioid configuration. After intravenous administration of antibiotics, the patient showed progressive improvement and was discharged for outpatient department follow up.
