BACKGROUND/AIMS: Infection of pancreatic necrosis is one of the leading cause of death in patients with severe necrotizing pancreatits. Because of high mortality rate up to 50%, immediate surgical debridement including pancreatectomy is recommended. However, early surgical treatment still showed high mortality rate and better treatment strategy is required. This study was conducted to evaluate the outcomes of early intensive non-surgical treatments in patients with infected necrotizing pancreatitis. METHODS: This study was based on retrospective analysis of 71 patients with acute severe necrotizing pancreatitis (APACHE II score>or=8, or Ranson's score>or=3, and pancreatic necrosis on CT scan), who were admitted to medical center during past 16 years. Infection of pancreatic necrosis was confirmed by fine needle aspiration, and early intensive medical treatments comprised of prophylactic antibiotics coverage, fluid resuscitation, organ preserving supportive measures, and percutaneous catheter drainage were carried out. RESULTS: Among the enrolled patients, infections were suspected in 46 patients, but fine needle aspirations were done only in 32 patients. In 21 patients, infections of necrotic tissue were confirmed by bacteriology, while other 11 patients showed no evidence of bacterial growth. Of 21 patients with infected necrosis, initial surgical interventions were performed in 2 patients, while initial medical treatments were performed in 19 patients. The success rate of medical treatment group in infected necrotizing pancreatitis was 79% (15/19). The mortality rate of medical treatment group and surgical treatment group was 5% (1/19) and 50% (1/2). CONCLUSIONS: Early intensive medical treatment seems to be a good therapeutic strategy, even if the infection has developed in pancreatic necrosis. Further prospective randomized studies are required to confirm this finding.

3.Spontaneous Bacterial Peritonitis.
The Korean Journal of Gastroenterology 2018;72(2):56-63
Spontaneous bacterial peritonitis (SBP) is defined as bacterial infections that occur in patients with cirrhosis and ascites without any significant intraperitoneal infection, accounting for approximately 10–30% of bacterial infections in hospitalized patients. SBP develops in patients with liver cirrhosis because bacterial translocations are increased by changes in the intestinal bacteria and mucosal barriers. In addition, the decreased host immune response cannot remove the bacteria and their products. The most common cause of SBP is Gram-negative bacteria, such as Escherichia coli and Klebsiella species, and infections by Gram-positive bacteria are increasing. SBP is diagnosed by the presence of >250 polymorphonuclear leukocyte/mm³ in ascites after paracentesis. If SBP is diagnosed, empirical antibiotic therapy should be started immediately. Empirical antibiotic treatment should distinguish between community acquired infections and nosocomial infections. Cirrhotic patients with gastrointestinal bleeding or low ascitic protein concentrations should consider primary prevention and those who recover from SBP should consider secondary prevention. This review describes the pathophysiology, diagnosis, treatment, and prevention of SBP.

OBJECTIVETo monitor and analyze the arthroplasty related infection situations of Drum Tower Hospital, so as to provide evidences for the prevention of infection after arthroplasty.
METHODSMonitoring of infection situations of nine arthroplasty operations were carried out from July to August in 2008. Five sampling methods were used to monitor the air of the 30 m2 surgery for 4 times. Through the cotton swab sampling, hands of 14 surgeons and 76 samples of surgical instruments (forceps, surgical scissors, retractors) were collected and then for bacterial culture.
RESULTSThe average amount of the total number of free-floating bacteria in our surgery was 88.2 cfu/m3. For the germiculture, 8 samples of hand detections were positive; 11 samples of surgical instruments including those used and unused and exposed at different times were positive.
CONCLUSIONIn the surgery of arthroplasty, all operation personnels should protect the air cleanliness degree, obey the surgical hand-washing rules and diminish the exposed time of aseptic table.

These guidelines were developed as part of the 2016 Policy Research Servicing Project by the Korea Centers for Disease Control and Prevention. A multidisciplinary approach was taken to formulate this guideline to provide practical information about the diagnosis and treatment of adults with acute upper respiratory tract infection, with the ultimate aim to promote the appropriate use of antibiotics. The formulation of this guideline was based on a systematic literature review and analysis of the latest research findings to facilitate evidence-based practice, and focused on key questions to help clinicians obtain solutions to clinical questions that may arise during the care of a patient. These guidelines mainly cover the subjects on the assessment of antibiotic indications and appropriate selection of antibiotics for adult patients with acute pharyngotonsillitis or acute sinusitis.

OBJECTIVEChronic granulomatous disease (CGD) is a rare primary immunodeficiency of phagocytic oxidative bursts leading to recurrent severe bacterial and fungal infections as well as granuloma formation. There were few reports on the clinical characteristics of this disease in China. The purpose of this study was to evaluate the clinical features of 48 Chinese cases with CGD which were confirmed by clinical features, dihydrorhodamine (DHR) assay and gene mutation analysis.
METHODThe study cohort was the population of CGD patients diagnosed in Children's Hospital of Fudan University from January, 2004, to June, 2011. Cases included in our analysis were restricted to those who had complete data of the clinical symptoms and laboratory tests. The patients were followed up by outpatient visiting and telephone call regularly for 0.5 to 6 years. The history and data of physical examination and treatment of 48 cases were collected and reviewed.
RESULTAll the patients were diagnosed by DHR analysis. The age of onset of all the 48 patients were less than 6 months, including 43 male and 5 female. The mean age at diagnosis was 2.42 years; 12 patients were infants under six months, 10 were between 6 and 12 months, 9 were between 1 and 2 years, 5 patients were between 2 and 3 years, 4 were between 4 and 5 years, and 8 were between 6 and 10 years. Recurrent respiratory infection (44/48) and chronic diarrhea (31/48) were the common symptoms in all the patients, and then skin lesion (22/48), including marked reaction at BCG infected site, pustular eruption and infected skin ulcer and urinary tract infection (3/48) were also general symptoms in our study. In addition, lymphadenectasis occurred in 31 cases and 23 of them were considered to be associated with BCG vaccination. The pathogens caused the infection were mycobacteria (52.08%), fungi (43.75%) and pyogenic bacteria. Thirty-seven patients had mutations in CYBB/CYBA/NCF1/NCF2 genes. Recombinant human interferon-gamma (rhIFN-γ) plus sulfamethoxazole were used for the prevention and treatment of infection, the frequency and severity of the disease could be reduced.
CONCLUSIONThe age at onset and diagnosis of the present group of CGD was younger. Clinical symptoms were associated with recurrent mycobacterial, fungal and pyogenic bacterial infection, which involved respiratory tract, alimentary tract, skin and lymph node. rhIFN-γ partially improved the prognosis of CGD.

Cervical spinal epidural abscess, caused by fish bone injury and a secondary infection by Eikenella corrodens which is part of the normal flora, has not been reported. A 72-yr-old man came to the hospital with pain in his posterior neck and both shoulders for 2 months. He also was experiencing weakness on his right side for 3 days. A fish bone had been stuck in his throat for about 2 months. Neurological examination revealed right hemiparesis, hypesthesia on the left extremities and neck stiffness. Laboratory findings showed an elevated ESR/CRP and leukocytosis, and magnetic resonance imaging revealed a retropharyngeal abscess and cervical myelitis. The patient was treated with emergency surgical decompression and antibiotics. A fish bone was removed from the C3-C4 intervertebral disc space. In the culture of chocolate blood agar and 5% sheep blood agar plate, E. corrodens was detected as a causative organism.

A seasonal variation of glucose homeostasis in humans has been reported in various geographic regions. In this study, we examined seasonal variations in hemoglobin A1c (HbA1c) in patients with type 2 diabetes living in Korea. We analyzed 57,970 HbA1c values from 4,191 patients and the association of these values with ambient temperature for 3.5 yr. Overall, HbA1c exhibited its highest values from February to March and its lowest values from September to October (coefficient for cos t = -0.0743, P = 0.058) and the difference between the peak and nadir in a year was 0.16%-0.25%. A statistically significant seasonal variation was observed in the patients who were taking oral anti-diabetic drugs (OADs) without insulin treatment (coefficient for cos t = -0.0949, P < 0.05). The Spearman correlation coefficient between daily HbA1c values and the corresponding 3-month moving average ambient temperature was -0.2154 (95% confidence interval [CI]: -0.2711, -0.1580; P < 0.05). In conclusion, HbA1c values exhibited a seasonal variation in Korean patients with type 2 diabetes, with the highest values during the cold season, particularly in those who were treated with OADs, which should be taken into account in clinical practice for stable glucose control during the cold season.

A simplified polymerase chain reaction (PCR) assay was developed for fast and easy screening of mycoplasma mastitis in dairy cattle. Species of major mycoplasma strains [Mycoplasma (M.) bovis, M. arginini, M. bovigenitalium, M. californicum, M. bovirhinis, M. alkalescens and M. canadense] in cultured milk samples were detected by this simplified PCR-based method as well as a standard PCR technique. The minimum concentration limit for detecting mycoplasma by the simplified PCR was estimated to be about 2.5 x 10(3) cfu/mL and was similar to that of the standard PCR. We compared the specificity and sensitivity of the simplified PCR to those of a culture method. Out of 1,685 milk samples cultured in mycoplasma broth, the simplified PCR detected Mycoplasma DNA in 152 that were also positive according to the culture assay. The sensitivity and specificity of the simplified PCR were 98.7% and 99.7%, respectively, for detecting mycoplasma in those cultures. The results obtained by the simplified PCR were consistent with ones from standard PCR. This newly developed simplified PCR, which does not require DNA purification, can analyze about 300 cultured samples within 3 h. The results from our study suggest that the simplified PCR can be used for mycoplasma mastitis screening in large-scale dairy farms.
