RESUMEN
BACKGROUND/AIMS: Abdominal bloating is a troublesome complaint due to insufficient understanding of the pathophysiology. The aim of this study was to evaluate the efficacy of rifaximin in reducing bloating associated with functional gastrointestinal disorders (FGIDs). METHODS: A total of 63 patients were treated with rifaximin for FGIDs with bloating or gas-related symptoms between 2007 and 2013 at Seoul National University Bundang Hospital. Rifaximin was administered at a dose between 800 mg/day and 1,200 mg/day for 5 to 14 days. The proportion of patients who had adequate relief of global FGID symptoms and FGID-related bloating was retrospectively assessed. The response was recorded when the symptoms were reduced by at least 50% at the follow-up after treatment cessation. RESULTS: The mean age was 56.8±14.2 years; 49.2% were females. According to Rome III criteria, 20.6% (13/63) had irritable bowel syndrome (IBS) with constipation, 9.5% (6/63) had IBS with diarrhea, 4.8% (3/63) had mixed IBS, 23.8% (15/63) had functional dyspepsia, and 12.7% (8/63) had functional bloating. Of the 51 subjects who were followed-up, 30 (58.8%) had adequate relief of global FGID symptoms and 26 (51.0%) experienced improvement of abdominal bloating after rifaximin treatment. The proportion of female was slightly higher in non-response group than in the response group (60.0% vs. 34.6%, p=0.069). Otherwise, there was no difference between the two groups. CONCLUSIONS: Despite the limitations of this retrospective study, our data confirms that rifaximin may be beneficial for abdominal bloating. Further prospective clinical trial with a larger cohort is needed.

BACKGROUND/AIMS: Achalasia is classified into 3 types according to the Chicago classification. The aim of this study was to investigate characteristics and treatment outcomes of 3 achalasia subtypes in Korean patients. METHODS: Fifty-five patients diagnosed with achalasia based on conventional or high-resolution esophageal manometry were consecutively enrolled. Their clinical characteristics, manometric, endoscopic and esophagographic findings and treatment responses were analyzed among the 3 subtypes of achalasia. RESULTS: Of 55 patients, 21 (38.2%) patients had type I, 28 (50.9%) patients had type II and 6 (10.9%) patients had type III. The median follow-up period was 22.4 (interquartile range, 3.6-67.4) months. Type III patients were older than type I and II patients (70.0 vs. 46.2 and 47.6 years, P = 0.023). The width of the esophagus in type I patients was wider with more frequent bird's beak appearance on esophagogram than the other 2 types (P = 0.010 and 0.006, respectively). Of the 50 patients who received the evaluation for treatment response at 3 months, 7 patients (36.8% vs. 26.9%) were treated with pneumatic dilatation and 4 patients (21.1% vs. 15.4%) with laparoscopic Heller's myotomy in type I and II groups, respectively. The treatment responses of pneumatic dilatation and Heller's myotomy in type I group were 71.4 and 50.0% and in type II were 85.7 and 75.0%, respectively, and all 5 patients in type III group showed good response to medical therapy. CONCLUSIONS: Clinical characteristics of 3 achalasia subtypes in Korean patients are consistent with other studies. Treatment outcomes are variable among 3 subtypes.

Abdominal bloating is a very common and troublesome symptom of all ages, but it has not been fully understood to date. Bloating is usually associated with functional gastrointestinal disorders or organic diseases, but it may also appear alone. The pathophysiology of bloating remains ambiguous, although some evidences support the potential mechanisms, including gut hypersensitivity, impaired gas handling, altered gut microbiota, and abnormal abdominal-phrenic reflexes. Owing to the insufficient understanding of these mechanisms, the available therapeutic options are limited. However, medical treatment with some prokinetics, rifaximin, lubiprostone and linaclotide could be considered in the treatment of bloating. In addition, dietary intervention is important in relieving symptom in patients with bloating.

Here, we report a case of primary cryptococcal tenosynovitis and arthritis caused by worsened cellulitis in a patient with rheumatoid arthritis (RA) who had been taking methotrexate and leflunomide. The patient, injured during the soybean harvest, failed to respond to empirical antibiotic therapy for presumed bacterial cellulitis on the dorsum of the right hand. An operative procedure was performed. Cryptococcocal tenosynovitis was diagnosed upon histopathological examination of the lesion. Treatment with 400 mg of fluconazole daily for 3 months led to the complete disappearance of skin lesions, with slight limitation of finger extension. The patient was examined continuously for 2 years, and there was no evidence of relapse or dissemination to other organs. This case indicates that primary cryptococcal skin and soft tissue infections must be included in the differential diagnoses of antibiotics-refractory soft tissue infections, especially in immunocompromised patients.

BACKGROUND: Tigecycline (TIG), a new broad-spectrum glycylcycline with anti-multidrug-resistant-(MDR)-pathogen activity, was launched in March 2009 in South Korea, but there are insufficient clinical studies on its use in the country. As such, this study was performed to analyze cases of severe MDR-pathogen-caused infections treated with TIG. METHODS: Patients treated with TIG within the period from May 2009 to June 2010 were enrolled in this study. Their clinical and microbiologic data were reviewed retrospectively. RESULTS: Twenty-one patients were treated with TIG for complicated skin and soft-tissue infections (cSSTIs) (42.9%), complicated intra-abdominal infections (cIAIs) (38.1%), or pneumonia (19.1%) caused by MDR pathogens like carbapenem-resistant Acinetobacter baumannii (76.2%), methicillin-resistant Staphylococcus aureus (61.9%), extended-spectrum beta-lactamase-producing Escherichia coli and Klebsiella pneumoniae (38.1%), and penicillin-resistant Enterococcus species (33.3%). Thirteen patients (61.9%) had successful clinical outcomes while five (23.8%) died within 30 days. The rate of clinical success was highest in cSSTI (77.8%), followed by cIAI (50%) and pneumonia (50%), and the mortality rate was highest in pneumonia (50%), followed by cIAI (25%) and cSSTI (11.1%). CONCLUSION: Tigecycline therapy can be an option for the treatment of severe MDR-pathogen-caused infections in South Korea. Due to its high risk of failure and mortality, however, prudence is required in its clinical use for the treatment of severe infections like nosocomial pneumonia.

BACKGROUND/AIMS: Although only a few sporadic cases of Q fever have been reported in Korea, a total of 13 cases have been seen in our area. We performed this study to evaluate the clinical characteristics of these cases of acute Q fever. METHODS: Demographic features, clinical manifestations, laboratory and radiologic findings, and therapeutic outcomes of all cases were evaluated. Q fever was diagnosed using an indirect micro-immunofluorescence assay (MIFA) and polymerase chain reaction (PCR). RESULTS: A total of 13 patients with acute Q fever seen from January 2006 to August 2008 at three teaching hospitals in the Daegu Metropolitan City area were enrolled. The mean age was 49 years old (range, 24~76), and the male to female ratio was 11:2. Six (46.2%) cases had a history of animal contact. Fever (100%) was the most common manifestation, followed by myalgia (84.6%), headache (61.5%), anorexia (61.5%), and chills (61.5%). All cases were diagnosed with high titers of anti-phase II antibody (IgM> or = 1:50, IgG> or =1:200) and positive nested PCR for the 27-kDa OMP com-1 gene of Coxiella burnettii in the blood. In three cases, liver biopsies revealed the presence of compact fibrin-ring granulomas. No characteristics of pneumonia were diagnosed on chest X-rays. The predominant presentation was acute febrile illness with hepatitis, including three cases (27.3%) of severe cholestatic hepatitis. The most frequently used antimicrobial agent was doxycycline (84.6%), followed by azithromycin (7.7%). CONCLUSIONS: Acute Q fever may be added to the list of differential diagnosis of patients with acute febrile illness and hepatitis in the Daegu Metropolitan City area.
