A 3 year and 3 months old boy with recurrent infections since his age of 5 months was presented with clinical data and autopsy findings. He was the 4th product of healthy parents. His elder brother died of recurrent perianal abscess and sepsis at his age of 3 years. His 2nd elder sister died on the 14th day of life probably from the complication of BCG vaccination. Beginnig with perianal abscesses at his age of 5 months, he has been continuously suffering from recurrent infections such as arthritis, ostomyelitis, pneumonia, epididymitis, subcutaneous abscesses and perianal abscesses. In spite of meticulous supportive and aggressive antibiotic therapy persistent positive cultures for staph. Aureus, klebsiella, E. Coli, Enterococcus and coliform bacilli from different sited were noted. Erythrocyte sedimentation rate of 25 to 40 were constant. White cell count varied frem 15500 to 33400 with polymorphonucleocytes predominance. NBT test showed persistent low scoring of 2% throught the course. He finally died of pneumonia and empyema. At postmortem examination, multiple abscesses and grnulomas of right lung and multipe granulomas in the liver, spleen, lymph node, bone, marrow, adrenal gland, kidney and intestinal wass were noted. At microscopic examination histiocytic granulomas with lipid containing histiocyte infiltrations were noted in every organs described including brain.

BACKGROUND/AIMS: Phosphatase and tensin homolog (PTEN) is a known tumor suppressor gene that is downregulated in hepatocellular carcinoma (HCC). Here, we investigated the association between single nucleotide polymorphisms (SNPs) of PTEN and HCC development in patients with hepatitis B virus (HBV) infection. METHODS: Six SNPs of PTEN at positions rs1234221, rs1903860, rs1234220, rs1903858, rs2299941, and rs17431184 were analyzed in a development population (417 chronic HBV carriers without HCC and 281 chronic HBV carriers with HCC). PTEN rs1903858, rs1903860, and rs2299941 SNPs were further assessed for the development of HCC in a validation population of 200 patients with HBV-related liver cirrhosis. RESULTS: In the development population, PTEN rs1903860 C allele, rs1903858 G allele, and rs2299941 G allele were associated with a low risk of HCC. The haplotype A-T-A-A-A was associated with an increased risk of HCC (recessive model; odds ratio=2.277, 95% confidence interval [CI] =1.144-4.532, P=0.019). In the validation population, PTEN rs2299941 G allele was the only significant protective genetic polymorphism related to HCC development after adjustment for age and sex (hazard ratio=0.582, 95% CI =0.353–0.962, P=0.035). CONCLUSIONS: These findings suggest that genetic polymorphisms in PTEN may affect HCC development in patients with chronic HBV infection.

Background: Aortic dissection (AD) is one of the most catastrophic diseases and is associated with high morbidity and mortality. The aim of this study is to investigate the hospital incidence and mortality rates of thoracic AD in Korea using a nationwide database. Methods: We conducted a nationwide population-based study using the health claims data of the National Health Insurance Service in Korea. From 2005 to 2016, adult patients newly diagnosed with AD were included. All patients were divided into the following four subgroups by treatment: type A surgical repair (TASR), type B surgical repair (TBSR), thoracic endovascular aortic repair (TEVAR), and medical management (MM). The incidence rate, mortality rate, and risk factors of in-hospital mortality were evaluated. Results: In total, 18,565 patients were newly diagnosed with AD (TASR, n = 4,319 [23.3%];TBSR, n = 186 [1.0%]; TEVAR, n = 697 [3.8%]; MM, n = 13,363 [72.0%]). The overall AD incidence rate was 3.76 per 100,000 person-years and exhibited a gradual increase during the study period (3.29 to 4.82, P < 0.001). The overall in-hospital mortality rate was 10.84% and remained consistent (P = 0.57). However, the in-hospital mortality rate decreased in the TASR subgroup (18.23 to 11.27%, P = 0.046). An older age, the female sex, hypertension, and chronic kidney disease were independent risk factors for in-hospital mortality. Conclusion The incidence of thoracic AD has gradually increased in Korea. The in-hospital mortality in the TASR subgroup decreased over the decade, although the overall mortality of AD patients did not change.

BACKGROUND/AIMS: In hospitalized patients with acute steroid-refractory UC, infliximab has been demonstrated to be one of the medical rescue therapies to avoid colectomy. We report the result of a retrospective observational study to find the efficacy and safety of infliximab as a rescue therapy in our hospital. METHODS: Between January 2007 and January 2010, 9 hospitalized patients with steroid-refractory UC were selected to receive three infusions of infliximab (5 mg/kg), at weeks 0, 2, and 6. Efficacy of treatment was evaluated at 8 weeks after the first infliximab infusion and at the end of follow-up period. Adverse events related to infliximab rescue therapy were also collected. RESULTS: Seven patients (77.8%) had completed 3 infusions of infliximab and achieved clinical response at 8 weeks after the first infliximab infusion. Clinical remission rate and the rate of mucosal healing at 8 weeks were 57.1% (4/7) and 71.4% (5/7), respectively. They were followed up for median time of 24.9 months (19.5-53.6 months). One patient underwent emergency colectomy at weeks 2, due to colon perforation, while another patient had discontinued infliximab treatment at weeks 4, because of Clostridium difficile-associated colitis. Finally, colectomy was avoided in 77.8% (7/9) of cases. There was no mortality. CONCLUSIONS: Rescue therapy with infliximab has sustained clinical benefit in 88.9% of our hospitalized patients with acute steroid-refractory UC. Future prospective and long-term follow-up trials with a large number of patients are needed to confirm the efficacy and safety of the treatment.

PURPOSE: A solid pseudopapillary tumor (SPT) is a rare pancreatic neoplasm, with low malignant potential, which tends to occur predominantly in younger females. Most patients are diagnosed due to the abdominal pain or the large palpable abdominal mass. The treatment is surgical resection, using either enucleation or more radical procedures. Only a few cases of SPT have been reported; therefore, the purpose of this study was to evaluate the clinicopathological characteristics and prognosis after surgical resection of this rare type of tumor. METHODS: In this paper, twelve cases of SPT, treated at the Department of Surgery, Chonnam National University Hospital, between 1994 and 2003, are presented. RESULTS: 10 females, with a mean age of 32.2 years, ranging from 14 to 48, and 2 males, aged 15 and 32, were diagnosed. The tumors were large, with a mean resected diameter of 7 cm, had cystic degene rations between the solid areas, and were distributed in the head (7 cases) and the body-tail (5 cases) of the pancreas. Immunohistochemical studies were performed in 7 patients, which revealed the majority of the cases to be a-1 antitrypsin and neuron specific enolase (NSE) positive. The surgical managements of the tumors included enucleation (6 cases) or more radical procedures, such as a distal pancreatectomy (5 cases) and pancreaticoduodenectomy (1 case). There was no recurrence after the complete surgical resection. CONCLUSION: The mainstay of treatment in patient with a SPT is surgical resection, after which the prognosis was favorable.

Early post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) prediction may allow safe same-day outpatients discharge after ERCP and earlier proper management. This study aimed to assess the usefulness of the 4-hour post-ERCP serum amylase and lipase levels for PEP early prediction and to investigate predictive cut-off values for 4-hour post-ERCP serum amylase and lipase levels for safe discharge and urgent initiation of resuscitation. The data of 516 consecutive patients with native papilla who underwent ERCP between January 2013 and August 2014 were retrospectively reviewed. Serum amylase and lipase levels were measured before, and 4 and 24 hours after ERCP. PEP occurred in 16 (3.1%) patients. The receiver-operator characteristic curve for 4-hour post-ERCP serum amylase and lipase levels showed that the areas under the curve were 0.919 and 0.933, respectively, demonstrating good test performances as predictors for PEP (both P values < 0.001). The amylase level > 1.5 × the upper limit of reference (ULR) was found useful for PEP exclusion with a sensitivity of 93.8%, while 4 × ULR was found useful to guide preventive therapy with the best specificity of 93.2%. Similarly, the lipase level 2 × ULR showed best sensitivity, while 8 × ULR had the best specificity. Logistic regression analysis showed that 4-hour post-ERCP amylase level > 4 × ULR, lipase level > 8 × ULR, precut sphincterotomy, and pancreatic sphincterotomy were significant predictors for PEP. In conclusion, 4-hour post-ERCP amylase and lipase levels are useful early predictors of PEP that can ensure safe discharge or prompt resuscitation after ERCP.

BACKGROUND: A web-based surveillance of surgical-site infections (SSIs) in Korean Nosocomial Infections Surveillance System (KONIS) was performed to determine the incidence of SSIs after 15 operative procedures. METHODS: Forty-three hospitals participated in the surveillance system for 15 operative procedures. A year-round observation was carried out, and the duration of participation was shortened for 3 months unit. All data were collected using a real-time web-based reporting system. RESULTS: From July 2010 through June 2011, SSI surveillance data of 18,644 cases were collected from 43 hospitals. SSIs were found to occur in 2.10% of the total cases. The SSI rates after various surgeries were as follows: 4.49%, rectal surgery; 4.41%, colon surgery; 3.50%, gastric surgery; 3.12%, craniotomy; 1.25%, abdominal hysterectomy; 0.93%, laminectomy; 0.63%, cesarean section; 0.62%, gallbladder surgery; and 0.54%, vaginal hysterectomy. The interim results of implant-related surgery are given below as SSI rates: 3.78%, ventricular shunt operation; 3.23%, coronary artery bypass graft; 2.20%, cardiac surgery; 1.31%, spinal fusion; 0.96%, knee prosthesis; and 0.88%, hip prosthesis. CONCLUSION: The SSI rate was found to be 2.10% by the KONIS 2010. The maintenance of a surveillance system for SSI is very important, as it will help in decreasing SSIs via feedback to the involved surgeons and infection-control personnel.
