BACKGROUND: Several antibiotics can be used to treat ventilator-associated pneumonia caused by carbapenem-resistant A. baumannii (CRAB-VAP) including high-dose sulbactam. However, the effectiveness of high-dose sulbactam therapy is not well known. We report our experience with high-dose sulbactam for treatment of CRAB-VAP. METHODS: Medical records of patients with CRAB-VAP who were given high-dose sulbactam between May 2013 and June 2015 were reviewed. RESULTS: Fifty-eight patients with CRAB-VAP were treated with high-dose sulbactam. The mean age was 72.0 ± 15.2 years, and the acute physiology and chronic health evaluation II (APACHE II) score was 15.1 ± 5.10 at the time of CRAB-VAP diagnosis. Early clinical improvement was observed in 65.5% of patients, and 30-day mortality was 29.3%. Early clinical failure (odds ratio [OR]: 8.720, confidence interval [CI]: 1.346-56.484; p = 0.023) and APACHE II score ≥ 14 at CRAB-VAP diagnosis (OR: 10.934, CI: 1.047-114.148; p = 0.046) were associated with 30-day mortality. CONCLUSIONS: High-dose sulbactam therapy may be effective for the treatment of CRAB-VAP. However, early clinical failure was observed in 35% of patients and was associated with poor outcome.

Pseudo-inflammatory tumors are also known as plasma cell granuloma, inflammatory pseudo-tumor and inflammatory myofibroblastic tumor, and these tumors are a group of highly variable proliferations of myofibroblastic cells that are associated with a prominent inflammatory infiltrate. This tumor is known to most commonly occur in the lungs, bladder and gastrointestinal system with only a few cases having been reported in the skin. A previously healthy 26-year-old man presented with a 6-year history of an intermittently pruritic lesion on his back. On the histologic examination, there were spindle cells in fascicles and a mixed inflammatory cellular infiltrate of plasma cells and lymphocytes. A diagnosis of inflammatory fibroblastic tumor was made and the nodule was surgically removed. We report here on an additional case of this rare cutaneous entity, and it is probably the first such report from Korea.

PURPOSE: The purpose of this study was to observe and compare the changes in the patterns of hemodynamic and blood profiles on the circuit of Extra-corporeal life support system (ECLS) by using a dual pulsatile pump (T-PLS). METHODS: An acute heart failure model using partial pulmonary artery banding was constructed in 12 piglets (20 -25kg). The animals were divided into centrifugal (n=6) and dual pulsatile pump (n=6) group. Each animal was placed on an ECLS system with a membrane oxygenator bypassing the right atrium and the aorta for 2 hours under general anesthesia. The parameters mainly observed were intra-circuit pressure changes, arterial pulsatility (pulse pressure), plasma free hemoglobin, hemodynamic changes, and other blood profiles. The parameters obtained just prior to the bypass were compared with the corresponding parameters obtained two hours after the bypass. RESULTS: Before bypass, the parameters were statistically the same between the groups. Two hours after the bypass, no significant differences were observed between the groups in ABGA, VBGA, AST/ALT, BUN/Cr, and electrolytes; the plasma free hemoglobin was 14.8+/-4.7 g/dl in the dual pulsatile group and 19.1+/-9.1 g/dl in the centrifugal group (p=NS). The pulse pressure was higher in the dual pulsatile pump than in the centrifugal pump group (35+/-8 vs. 11+/-7 mmHg, p=0.0253 mmHg). The highest circuit pressure was generated at the inlet of the membrane oxygenator and was higher in the dual pulsatile group than in the centrifugal group (173+/-12 mmHg vs. 222+/-8 mmHg, p=0.0000). CONCLUSION: The results demonstrate that a dual pulsating mechanism lessens blood cell trauma while providing physiologic pulsatile blood flow. The ECLS system using a dual pulsatile pump (T-PLS) can be useed as an effective and safe driving motor for an ECLS.

Extramammary Paget's disease is a rare clinicopathologic entity. Because it is often associated with a subjacent or visceral malignancy and recurrence, extramammary Paget's disease is considered as malignant condition. We present one case of extramammary Paget's disease involving the penis and scrotum with clinical presentation and brief review of relevant literature.

BACKGROUND: Bronchoconstriction associated with aerosolized agents delivered by a metered dose inhaler (MDI) is relatively uncommon, but has been of particular interest. MATERIAL AND METHOD: In this study, we investigated to what extent the inert ingredients and propellants (freons) influence pulmonary function in 25 asthmatic patients. Forced expiratory volume in one second(FEV,) was measured by spirometry, Autospira HI 498(Chest, Japan) before and 1, 3, 5 and 10 minutes after the inhalation of saline control and MDI-placebo containing freons and inert ingredients. RESULT: Twenty four % (6/25) of asthmatics experienced a decrease in FEV20 by 10% or greater when compared to saline control. Number of positive cases in steroid dependent asthmatics is significantly higher compared to non-steroid dependent asthmatics. (p<0.05) Bronchoconstriction associated with the use of MDI-placebo appeared within 3 to 5 minutes and resolved spontaneouly at 10 minutes after the inhalation. CONCLUSION: The bronchoconstrictive response induced by MDI might be caused by the pro-pellants and/or the other inert ingredients contained in MDIs.

BACKGROUND: Exercise can aggravate asthmatic symptoms in many patients with bronchial asthma. It is caused by that inhaled air bypasses nasal cavity and goes directly to the lower airways through open mouth dring exercise. Although the pathogenetic mechanisms of exercise-induced asthma(EIA) have not been clarified yet, there is evidence that chemical mediators, released from the inflammatory cells triggered by airway cooling or drying, might be responsible for induction of bronchoconstriction. However, it has been controversial which chemical mediators or cells are involved in such process. Objectiye . The aim of this study was to evaluate the role of activated mast cells in the pathogenesis of EIA and find out whether or not sulfidopeptide leukotrienes (LTC4/d4/E4) are involved in the exercise-induced bronchoconstriction. MATERIAL AND METHOD: Eleven asthmatics with documented exercise-induced bronchoconstriction and 10 control subjects were studied. Before and 6 hours after free running for 6 minutes, forced expiratory volume in 1 second (FEV,) and the concentrations of N- methylhistamine, LTE4, and creatinine in unine collected for 6 hours after exercise were determined. RESULT: Urinary concentrations of N-methylhistamine(mean+SE, ng/mg creatinine) of EIA patients before and after exercise were 159+40 and 450+75, respectively. Those of control subjects were 208+ 54 and 275+ 62, respectively. Uninary N-methylhistamine levels of EIA group increased significantly after exercise, while those of control group did not change. Urinary concentrations of LTE,(mean+SE, pg/mg creatinine) of EIA patients before and after exercise were 15.6 k2.6 and 22.2+5.8, respectively. Those of control subjects were 10.4+ 4.0, 18.2 +7.0, respectively. The concentrations of LTE4 in the urine samples collected before exerise revealed no difference between EIA and control subjects (p=0.07). There was no change after exercise in both groups. Percent fall of FEV, was 29.1+8.0% (mean+SD) in EIA group and 3.4 + 4.0% in control group, respectively. There was no correlation between reduction of FEV, and change in urinary concentrations of N-methyl-histmine after exercise. CONCLUSTION: Chemical mediators of activated mast cells may be involved in exercise-induced bronchoconstriction, but there is little evidence for enhanced sulfidopeptide leukotriene generation as assessed by urinary LTE4.

Tsutstugamushi disease is a major febrile disease that generally occurs in the fall in Korea with hemorrhagic fever with renal syndrome and leptospirosis. This disease is often accompanied by interstitial pneumonia, acute renal failure and liver failure. The causative agent, namely Orientia tsutsugamushi, is transmitted to humans through the bite of a laval trombiculid mite, which is commonly known as a chigger. A 78 year old man was admitted in October 2004 with intractable fever and a drowsy mentality. Two weeks earlier, he visited a private clinic complaining of a simple skin rash. He was treated with antihistamine and steroid, but his symptoms were aggravated and he was referred to our hospital. His physical examination and laboratory findings showed a septic shock status. The maculopapular rash had spread over his face, chest, abdomen and extremities. Eschar was observed in lower back area but it was too difficult to distinguish it from other skin rashes. His chest X-ray appeared as diffuse nodular patchy consolidations in the bilateral lung parenchyme. He was treated with a mechanical ventilator and doxycycline under th suspicion of Tsutstugamushi disease. However, he suffered multiorgan failure accompanied by acute respiratory distress syndrome, acute renal failure and acute hepatitis. He was treated in the intensive care unit for approximately 12 weeks and his general condition was recovered.

Pneumatosis intestinalis is an uncommon condition that is characterized by the presence of gas within the bowel wall. We experienced a case of pneumatosis intestinalis after cession of chemotherapy and we herein report on this case. A 58-year old man was admitted to our hospital for the evaluation of incidentally recognized pneumatosis intestinalis. He was diagnosed as having non small cell lung cancer in August 2006 and he received radiation therapy for concomitant brain metastasis and SVC syndrome in September 2006. He achieved a partial response after completing 6 cycles of chemotherapy with gemcitabine and cisplatin. Newly enlarged lymph nodes were observed on the follow-up CT, and chemotherapy with paclitaxel and carboplatin was started in July 2007. Due to the lack of a response, the therapeutic regimen was switched to oral erlotinib. After 1 month of treatment, the follow-up CT for response evaluation revealed pneumatosis intestinalis in the ascending colon without any subjective symptoms such as fever or abdominal pain. The laboratory results were within the normal range except for a slight increase of leukocytes. He underwent right hemicolectomy, but he didn't survive his postoperative acute renal failure and pneumonia

The primary cause of hemoptysis is the bronchial artery. However, it should be noted that pulmonary artery and other vessels can cause hemoptysis. If the source of the bleeding is not determined after embolization, other evaluations are needed. Systemic-pulmonary anastomosis and pulmonary artery pseudo-aneurysm are rare vascular abnormalities with varying etiologies. An accurate and rapid diagnosis is needed in hemoptysis, since the cause may be life-threatening. We report a case of a 77-years-old man with persistent hemoptysis due to the right inferior phrenic artery - pulmonary artery anastomosis and pseudoaneurysm. After the embolization of the inferior phrenic artery, the hemoptysis was successfully treated.
