Mycobacterium abscessus Lung Disease in a Patient with Kartagener Syndrome / 결핵및호흡기질환

Primary ciliary dyskinesia (PCD) is characterized by the congenital impairment of mucociliary clearance. When accompanied by situs inversus, chronic sinusitis and bronchiectasis, PCD is known as Kartagener syndrome. The main consequence of impaired ciliary function is a reduced mucus clearance from the lungs, and susceptibility to chronic respiratory infections due to opportunistic pathogens, including nontuberculous mycobacteria (NTM). There has been no report of NTM lung disease combined with Kartagener syndrome in Korea. Here, we report an adult patient with Kartagener syndrome complicated with Mycobacterium abscessus lung disease. A 37-year-old female presented to our hospital with chronic cough and sputum. She was ultimately diagnosed with M. abscessus lung disease and Kartagener syndrome. M. abscessus was repeatedly isolated from sputum specimens collected from the patient, despite prolonged antibiotic treatment. The patient's condition improved and negative sputum culture conversion was achieved after sequential bilateral pulmonary resection.

Efficacy of Ecabet Sodium for Helicobacter pylori Eradication, Combined with Lansoprazole-Based Triple Regimen: A Prospective Study / 대한내과학회지

BACKGROUND/AIMS: Ecabet sodium is used for treating gastric ulcers and gastritis. It exhibits a bactericidal effect against Helicobacter pylori by inhibiting bacterial urease activity. Thus, ecabet sodium has been suggested to improve the efficacy of the H. pylori eradication in patients with peptic ulcers. The aim of this study was to compare the H. pylori eradication rate of lansoprazole-based triple therapy versus lansoprazole-based triple therapy plus ecabet sodium. METHODS: The subjects consisted of 363 H. pylori-positive patients who had undergone eradication therapy from February 2007 to February 2010. In total, 363 patients with H. pylori-positive peptic ulcer disease or symptomatic erosive gastritis received LAC (lansprazole 30 mg b.i.d., amoxicillin 1.0 g b.i.d., clarithromycin 500 mg b.i.d.) or LACE (lansoprazole 30 mg b.i.d., amoxicillin 1.0 g b.i.d., clarithromycin 500 mg b.i.d., ecabet sodium 1 g b.i.d.) for 1 week. Successful eradication was defined as a negative 13Curea breath test 4-5 weeks after treatment completion. RESULTS: H. pylori eradication rates were 81.4% (166/204) in the LAC group and 86.2% (137/159) in the LACE group (p = 0.159). No significant difference in eradication was observed. No significant difference was observed in the side effects experienced by the patients in the two treatment groups. CONCLUSIONS: Our results suggest that adding ecabet sodium did not improve the H. pylori eradication rate significantly in standard lansoprazole-based triple therapy for H. pylori.

Amiodarone-induced Pulmonary Toxicity within a Short Period of the Initiation of Amiodarone Therapy: A Case Report / 대한구급학회지

Amiodarone is one of the most commonly prescribed antiarrhythmic drug for almost all atrial or ventricular arrythmias. Amiodarone-induced pulmonary toxicity (APT) was first described in 1980 and has potentially serious side effects that are believed to develop in 5% of patients. In general, APT occurs only when high amiodarone doses are used for a long time. However, during short-term therapy of amiodarone, APT is rarely reported. In this report, we describe a case of amiodarone-induced pulmonary toxicity after a short course of amiodarone therapy for atrial fibrillation.

Two Cases of Spontaneous Pneumomediastinum Complicating Viral Pneumonia Caused by Influenza A Virus, (H1N1 Subtype): A Case Report / 대한구급학회지

Influenza A virus, (H1N1 Subtype), was identified as the cause of outbreaks of febrile respiratory infection in Mexico, the US, Canada and elsewhere during the spring of 2009. In Korea, a novel virus infection showing many variable complications was also pandemic. We report two cases of spontaneous pneumomediastinum, complicating viral pneumonia, caused by Influenza A virus, (H1N1 Subtype).

A case report of concurrent leptospirosis and salmonellosis infection / 대한내과학회지

A 37-year-old male patient presented with a fever, chills, and abdominal pain. The patient was diagnosed with Typhoid fever based on blood culture, but did not clinically respond to standard antibiotic (Ceftriaxone) therapy. On day 9, leptospira serology was positive and doxycycline was added to the treatment strategy. With combination therapy, the patient recovered from the infection. In most cases, similar clinical presentations make the diagnosis of concurrent infections of febrile diseases difficult, and serious complications can develop as a consequence of delayed treatment. As with this case, if the patient initially has serious a medical condition caused by complications, and does not clinically respond to initial standard antibiotics therapy or has an unusual course of disease, concurrent infection must be considered.
