PURPOSE: Single incision laparoscopic appendectomy (SILA) is a widely used surgical procedure for treatment of appendicitis with better cosmesis. However, many surgeons generally tend to choose conventional multiport laparoscopic appendectomy regarding with complicated appendicitis. The aim of this study is to demonstrate the safety and feasibility of SILA for treatment of complicated appendicitis by comparison with 3-ports conventional laparoscopic appendectomy (CLA). METHODS: Retrospective chart review of patients diagnosed appendicitis at single hospital during January 2015 to May 2017 collected 500 patients. Among 134 patients with complicated appendicitis, we compared outcomes for 29 patients who got SILA and 105 patients who got CLA. RESULTS: 179 and 321 patients were treated by SILA and CLA, respectively. 134 (26.8%) patients were treated for complicated appendicitis, 29 patients by SILA and 105 patients by CLA, respectively. There was no case converted to open or added additional trocar in both groups. There were no differences in demographics with regard to age, sex, body mass index (BMI), and American society of anesthesiologists (ASA) scores. There was no difference in mean operating time (58.97±18.53 (SILA) vs. 57.57±21.48 (CLA), p=0.751). The drain insertion rate (6.9% vs 37.1%, p=0.001) and the length of hospital stay (2.76±1.41 vs. 3.97±2.97, p=0.035) were lower in SILA group with significance. There was no significant difference in the rate of surgical site infection (6.9% vs. 6.7%, p=1.000). CONCLUSION: This study demonstrates that SILA is a feasible and safe procedure for treatment of complicated appendicitis.

Acinetobacter baumannii (AB) is a common pathogen found in patients with hospital-acquired pneumonia all over the world. Community-acquired AB pneumonia, however, is very rare and has seldom been reported in Asia-Pacific countries. Community-acquired AB pneumonia has a fulminant course and is associated with a higher mortality than hospital-acquired AB pneumonia. In Korea, no case of fatal community-acquired AB pneumonia has been reported to date. Here, we describe the first fatal case of fulminant community-acquired AB pneumonia in Korea.

Kidney transplantation and accompanying medical conditions may result in changes in body composition. Such changes have been evaluated in Caucasian recipients, but not in Asian recipients. Herein, we conducted a study on Asian recipients because Asians have a different body composition from Caucasians. A total of 50 Asian recipients was enrolled as a prospective cohort. Using bioelectrical impedance analysis, body composition (muscle and fat mass) was assessed after 2 weeks (baseline), and at 1, 3, 6, 9, and 12 months following kidney transplantation. To find predictors related to changes, the data were analyzed by multivariate analysis using forward selection. All of the patients had good graft function during the study period. Patients gained approximately 3 kg within 1 yr of kidney transplantation. The proportion of muscle mass significantly decreased (Ptrend = 0.001) and the proportion of fat mass significantly increased over time (Ptrend = 0.002). The multivariate results revealed that male recipients, deceased donor type, and low protein intake were associated with an increase in fat mass and a decrease in muscle mass. The results from this study may help to investigate differences in body composition changes between races, as well as the factors related to these changes.

Radiation therapy is one of the most important therapeutic modalities for the treatment of lung cancer. Radiation pneumonitis is one of the important complications associated with radiotherapy for lung cancer. Radiation pneumonitis is generally limited to the irradiated lung and is manifested by the insidious onset of dry cough, dyspnea, and mild fever, resulting in damage and edematous changes of alveolar structures on histologic inspection. Clinically, diffuse bilateral radiation pneumonitis accompanied with acute symptoms after unilateral thoracic irradiation appears very rarely. Histopathologic examinations for the diagnosis of out-of-field radiation pneumonitis are rarely performed. We herein describe a case of extensive bilateral radiation pneumonitis which developed acutely after salvage radiotherapy for squamous cell carcinoma in the left upper lobe of the lung. The condition was confirmed by a diagnostic help of histopathologic findings.

Streptococcus suis causes meningitis and sepsis in pigs, but human infection has increased over the past few years in those who are exposed to pigs or raw pork. Most cases have occurred in Southeast Asia, but only two cases have been reported in South Korea, presenting with arthritis and meningitis. Here, we report a rare case of S. suis infection, a 60-year-old sailor, who visited the emergency room presenting septicemia, pneumonia with empyema and meningitis, showed full recovery; however, neurologic sequale of severe cognitive dysfunction was present after the usage of antibiotics and percutaneous drainage. S. suis was isolated from blood and pleural fluid and the strain was susceptible to penicillin and vancomycin. Increased awareness of S. suis infection and prevention are warranted.

BACKGROUND/AIMS: Peroxiredoxin (Prx) belongs to a ubiquitous family of antioxidant enzymes that regulates many cellular processes through intracellular oxidative signal transduction pathways. Silica-induced lung damage involves reactive oxygen species (ROS) that trigger subsequent toxic effects and inflammatory responses in alveolar epithelial cells resulting in fibrosis. Therefore, we investigated the role of Prx in the development of lung oxidant injury caused by silicosis, and determined the implication of ROS in that process. METHODS: Lung epithelial cell lines A549 and WI26 were treated with 1% silica for 0, 24, or 48 hours, following pretreatment of the A549 cells with N-acetyl-L-cysteine and diphenylene iodonium and no pretreatment of the WI26 cells. We transfected an HA-ubiquitin construct into the A549 cell line and then analyzed the cells via Western blotting and co-immunoprecipitation. RESULTS: Silica treatment induced cell death in the A549 lung epithelial cell line and selectively degraded Prx I without impairing protein synthesis in the A549 cells, even when the ROS effect was blocked chemically by N-acetyl-L-cysteine. A co-immunoprecipitation study revealed that Prx I did not undergo ubiquitination. CONCLUSIONS: Silica treatment induces a decrease of Prx I expression in lung epithelial cell lines regardless of the presence of ROS. The silica-induced degradation of Prx does not involve the ubiquitin-proteasomal pathway.

BACKGROUND: The nitric oxide (NO) released by inducible NO synthase (iNOS) plays an important role in the pathophysiology of sepsis. Corticosteroids also play a role in the hemodynamic and inflammatory reactions in sepsis. Both have been shown to have a relationship theoretically, but their correlation and clinical impacts have rarely been evaluated. METHODS: 26 patients with sepsis and 14 healthy controls were enrolled in this study. The initial random plasma total NO and the serum cortisol levels were measured. The same measurements were serially carried out on the 3rd, 5th, and 7th days. RESULTS: The initial total plasma levels of NO and cortisol were higher in the patients with sepsis than in the healthy controls. The total NO levels were higher in patients with severe sepsis than in the those with mild sepsis. There was a correlation between the total NO and cortisol level throughout the study. CONCLUSION: In patients with sepsis, the levels of plasma NO and cortisol were well correlated during the first week of sepsis, which suggests an interrelationship. However, the clinical and pathogenetic implications await further evaluation.

PURPOSE: Palpable lymph nodes are common in the pediatric population, and most of them are either inflammatory or congenital. As the diagnostic evaluation, fine needle aspiration cytology (FNAC) is known to be more convenient and economical than tissue biopsy. We evaluated the usefulness of FNAC in children and adolescents. METHODS: Four hundred and thirteen FNAC samples(M:F=1:1.15) were retrospectively analyzed in patients who were brought to Inha University Hospital, from August 1999 to August 2004. RESULTS: The most common age group was 16-20 years of age(N=148, 35.8 percent). The cervical area was the most frequently involved site(N=310, 75 percent). Non-specific lymphadenitis was the most common(N=227, 54.9 percent), followed by the benign neoplasm(N=59, 14.2 percent). Malignant tumors were 18 cases(4.3 percent), and congenital diseases were found in 10 cases(2.4 percent). In inflammatory lesions, tuberculous lymphadenitis(N=22, 5.3 percent) was the most common with a histologic sensitivity of 90.9 percent. The peripheral blood and serologic studies were non-specific. Fifty nine percent(N=244) of lymphadenitis improved without specific management. Antibiotics were prescribed in 15.2 percent of lymphadenitis and lymphadenectomy was performed in 12.6 percent. CONCLUSION: Most of the enlarged lymph nodes in children and adolescents were benign. These results show FNAC is a safe, rapid and reliable diagnostic procedure for the appropriate differential diagnosis of enlarged lymph nodes in children and adolescents.

Streptococcus pneumoniae has been a rare cause of endocarditis in the postantibiotic era. The incidence of pneumococcal endocarditis now accounts for less than 3% of all cases and most often occur in patients with risk factors, especially alcoholism. We report the case of a 68-year-old male with acute infective endocarditis due to Streptococcus pneumoniae. We stressed the low frequency of this agent as a cause of endocarditis and the atypical evolution of this case.

BACKGROUND: Corticosteroids are known to be significant prognostic parameters in sepsis. Recently, an absolute and relative insufficiency of the corticosteroids system has often been reported to often develop particularly in severe sepsis. Degree of such an adrenal insufficiency not only has prognostic implications but also can be used to guide corticosteroids replacement therapy. The 24-hour urinary cortisol levels as well as serum cortisol concentrations were measured to assess the clinical significance and their relationship with the other parameters of sepsis, and also evaluated the clinical implications of the relative adrenal insufficiency. METHODS: 26 consecutive patients with sepsis were enrolled. The basal random serum cortisol, ACTH, ADH, lactate levels and 24-hour urinary free cortisol amount were measured. The rapid ACTH (250 microgram) stimulation test was also performed. RESULTS: Basal serum cortisol levels were higher in the non-survivors than in the survivors. The 24-hour urinary free cortisol levels were higher in the patients with severe sepsis than in those without. The serum cortisol levels strongly correlated with the serum ADH and lactate levels. The 24-hour urinary free cortisol levels strongly correlated with the serum cortisol and lactate levels. The fractional changes in the cortisol levels after the rapid ACTH stimulation tests correlated with the serum cortisol, ADH, and lactate levels. CONCLUSION: Both the serum cortisol and 24-hour urinary cortisol were found to be significant prognostic factors in sepsis, and showed a strong correlation with the other parameters. The relative adrenal insufficiency might also be an important clinical parameter.

BACKGROUND: Although central venous catheters have become lifelines for the critically ill patients, these devices represent a major source of nosocomial bloodstream infections. We performed a study to investigate the rates of catheter colonization and bloodstream infection associated with the site of placement and indwelling time. MATERIALS AND METHODS: We studied prospectively the rate of central venous catheter related infections and colonization from May to August 2002. At the time of central venous catheter removal, two sets of peripheral blood cultures were obtained and catheter tip culture was performed using roll-plate semiquantitative method and broth culture. RESULTS: The rates of catheter colonization and bloodstream infection were 10.1%, 8.9%, respectively. Based on catheter indwelling time, catheter colonization and bloodstream infection occurred in 10.6 and 5.0 cases per 1000 catheter day, respectively. The leading organisms causing catheter related bloodstream infection were Candida species (44%) and S. aureus (33.3%). Catheter colonization and bloodstream infection all began 7days after central venous catheter insertion and mean time were 20.5+/-9.8, 19.8+/-9.9 days respectively. CONCLUSION: The rate of central venous catheter colonization and bloodstream infection is high and it begins 7 days after central venous catheter insertion and mean time is about 20 days. There were no differences among sites of catheter placement.

BACKGROUND: Peroxiredoxins (Prxs) are a relatively newly recognized, novel family of peroxidases that reduce H2O2 and alkylhydroperoxide into water and alcohol, respectively. There are 6 known isoforms of Prxs present in human cells. Normally, Prxs exist in a head-to-tail homodimeric state in a reduced form. However, in the presence of excess H2O2, it can be oxidized on its catalytically active cysteine site into inactive oxidized forms. This study surveyed the types of the Prx isoforms present in the pulmonary epithelial, macrophage, endothelial, and other cell lines and observed their response to oxidative stress. METHODS: This study examined the effect of exogenous, excess H2O2 on the Prxs of established cell lines originating from the pulmonary epithelium, macrophages, and other cell lines, which are known to be exposed to high oxygen partial pressures or are believed to be subject to frequent oxidative stress, using non-reducing SDS polyacrylamide electrophoresis (PAGE) and 2 dimensional electrophoresis. RESULT: The addition of excess H2O2 to the culture media of the various cell-lines caused the immediate inactivation of Prxs, as evidenced by their inability to form dimers by a disulfide cross linkage. This was detected as a subsequent shift to its monomeric forms on the non-reducing SDS PAGE. These findings were further confirmed by 2 dimensional electrophoresis and immunoblot analysis by a shift toward a more acidic isoelectric point (pI). However, the subsequent reappearance of the dimeric Prxs with a comparable, corresponding decrease in the monomeric bands was noted on the non-reducing SDS PAGE as early as 30 minutes after the H2O2 treatment suggesting regeneration after oxidation. The regenerated dimers can again be converted to the inactivated form by a repeated H2O2 treatment, indicating that the protein is still catalytically active. The recovery of Prxs to the original dimeric state was not inhibited by a pre-treatment with cycloheximide, nor by a pretreatment with inhibitors of protein synthesis, which suggests that the reappearance of dimers occurs via a regeneration process rather than via the de novo synthesis of the active protein. CONCLUSION: The cells, in general, appeared to be equipped with an established system for regenerating inactivated Prxs, and this system may function as a molecular "on-off switch" in various oxidative signal transduction processes. The same mechanisms might applicable other proteins associated with signal transduction where the active catalytic site cysteines exist.

An 86 year old woman was admitted complaining of dyspnea and right pleuritic pain with a 5 week durations. A physical examination, chest X-ray, and diagnostic thoracentesis upon admission revealed findings consistent with severe pneumonia and empyema on the right lung. Despite the insertion of a chest tube and negative suction via Emersion pump, the continuous air leakage was sustained, and a bronchopleural fistula (BPF) was found on the chest-CT. A flexible bronchoscopic occlusion with an Endobronchial Watanabe Spigot (EWS) was performed after 56 days of admission. An 5 mm diameter EWS was successfully inserted into the anterior segmental bronchus of the right upper lobe by flexible bronchoscope. There was no aAir leakage detected after this procedure. The patient was discharged 30 days after the EWS occlusion.

A 45-year-old man was admitted for fever, myalgia, and generalized edema with multiple localized erythema. He had no healthy problem before these symptoms developed. Abdominal CT scan showed multiple abscess in the right buttock, left psoas, and both inguinal area. Blood and wound culture drawn during the hospitalization grew methicillin sensitive Staphylococcus aureus (MSSA). Although antibiotic therapy and incisional drainage of abscess pocket, acute renal insufficiency was progressed and massive pulmonary hemorrhage and acute respiratory failure were developed. In addition to antibiotics, plasmapheresis and steroid pulse therapy made him improved dramatically from acute renal failure and pulmonary hemorrhage. The renal biopsy showed pauci-immune crescentic glomerulonephritis (GN). This result supports that plasmapheresis and steroid therapy may be beneficial in the treatment of staphylococcal infection-associated GN as several groups reported.

BACKGROUND: Continuous growth stimulation by various factors, as well as chronic oxidative stress, may co-exist in many solid tumors, such as lung cancer. A new family of antioxidant proteins, the peroxiredoxins (Prxs), have been implicated in the regulation of many cellular processes, including cell proliferation, differentiation and apoptosis. However, a real pathophysiological significance of Prx proteins, especially in lung disease, has not been sufficiently defined. Therefore, this study was conducted to investigate the distribution and expression of various Prx isoforms in lung cancer and other pulmonary conditions. METHOD: Patients diagnosed with lung cancer, and who underwent surgery at the Ajou Medical Center, were enrolled. The expressions of Prxs, Thioredoxin (Trx) and Thioredoxin reductase (TR) were analyzed using proteomic techniques and the subcellular localization of Prx proteins was studied using immunohistochemistry on normal mouse lung tissue. RESULT: Immunohistochemical staining has shown the isoforms of Prx I, II, III and V are predominantly expressed in bronchial and alveolar lining epithelia, as well as in the alveolar macrophages of the normal mouse lung. The isoforms of Prx I and III, and thioredoxin were also found to be over-expressed in the lung cancer tissues compared to their paired normal lung controls. There was also an increased amount of the oxidized form of Prx I, as well as a putative truncated form of Prx III, in the lung cancer samples when analyzed using 2-dimensional electrophoresis. In addition, a 43 kDa intermediate molecular weight protein band, and other high molecular weight bands of over 20 kDa, recognized by the anti-Prx I antibody, were present in the tissue extracts of lung cancer patients on 1-Dimensional electrophoresis, which require further investigation. CONCLUSION: The over-expressions of Prx I and III, and Trx in human lung cancer tissue, as well as their possible chaperoning function, may represent an attempt by tumor cells to adjust to their microenvironment in a manner advantageous to their survival and proliferation, while maintaining their malignant potential.

Signet ring cell carcinoma of lung is an unique variant of mucin producing adenocarcinoma which is characterized by abundant intracellular mucin accumulation. Only a few cases of primary signet ring cell carcinoma of lung have been reported in the world wide literature. And we have, recently experienced one case of primary signet ring cell carcinoma of lung. A 55 years old man was evaluated for paralysis of lower extremities and was found to have lung cancer in the left upper and lower lobe with pleural, multiple spinal, bone and liver metastases. Signet ring tumor cells were revealed by cytologic examination of pleural fluids. And there were no evidence of signet ring cell carcinoma of other organs. Primary signet ring cell carcinoma of lung seems to have an aggressive behavior and therapeutic modalities could be different from those for signet ring cell carcinomas from other organs. Therefore it is important to separate primary signet ring cell adenocarcinoma of lung from metastatic tumors.

BACKGROUND: Psoas abscess is a rare condition with vague clinical presentations, therefore misdiagnosis or delayed diagnosis is often made. We have reviewed the characteristics of the clinical presentation, microbiology, and treatment of 24 patients with psoas abscess. METHODS: The records of all patients treated with psoas abscess at Ajou University Hospital between March, 1996 and May, 2001 were retrospectively reviewed. RESULTS: A total of 24 cases of psoas abscess were reviewed: among these 17 cases were due to secondary cases and seven cases were diagnosed as primary psoas abscess. The right side was affected in 11 cases, the left side in nine, and both sides in four. Methicillin-susceptible Staphylococcus aureus was the most frequent (7/24 cases) pathogen, which were detected in cultures from five of seven patients with primary abscesses, whereas Mycobacterium tuberculosis (6/17 cases) and mixed enteric flora were detected in secondary abscesses. Three of the patients with primary psoas abscess expired from septic shock. The mortality rate was 12.5%. CONCLUSION: A psoas abscess should be considered when any patient presents with nonspecific abdominal pain, back pain and fever. This condition may be diagnosed promptly with computed tomography. Treatment involves use of appropriate antibiotics, as well as drainage of the abscess. Antibiotic coverage must include S. aureus and enteric bacteria. However, in endemic areas (such as Korea), tuberculous infection should be also considered.

BACKGROUND: A decreased level of serum arginine vasopressin(AVP) and an increased sensitivity to an exogenous AVP is expected in patients with septic shock who often require a high infusion rate of catecholamines. The goal of the study was to determine whether an exogenous AVP infusion to the patients with septic shock would achieve a significant decrement in infusion rate of catecholamine vasopressors while maintaining hemodynamic stability and adequate urine output. METHODS: Eight patients with septic shock who require a high infusion rate of norepinephrine had received a trial of 4-hour AVP infusion with simultaneous titration of norepinephrine. Hemodynamic parameters and urine output were monitored during the AVP infusion and the monitoring continued up to 4 hours after the AVP infusion had stopped. RESULTS: Mean arterial pressure showed no significant changes during the study period(p=0.197). Norepinephrine infusion rate significantly decreased with concurrent AVP administration(p=0.001). However, beneficial effects had disappeared after the AVP infusion was stopped. In addition, hourly urine output showed no significant changes throughout the trials(p=0.093). CONCLUSION: Concurrent AVP infusion achieved the catecholamine vasopressor sparing effect in the septic shock patients, but there was no evidence of the improvement of renal function. Further study may be indicated to determine whether AVP infusion would provide an organ-protective effect to the septic shock patients.
