3.Mechanism of Severe Acute Pancreatitis: Focusing on Development and Progression.
Korean Journal of Pancreas and Biliary Tract 2015;20(3):115-123
Acute pancreatitis (AP) is an inflammatory disorder and the severity range from mild to severe form. The mortality of severe form of AP is still high despite of tremendous improvement of diagnostic modalities and therapeutic options. Although pathogenesis of AP is still not fully understood, autodigestion theory is regarded as an initial common pathophysiologic mechanism of AP for about 2 centuries. However, it is obscure which mechanisms are involving the disease severity. Upregulation of adhesion molecules, leukocytes, proinflammatory cytokines and chemokines are also concerned local injury, systemic exacerbation of inflammation and ultimately organ failure. In addition, transcription factor Nuclear factor-kappa B is also influence the severity through upregulate the proinflammatory genes. The patterns of acinar cell death are closely correlated with disease severity of AP. The degree of acinar cell apoptosis is reversed correlated whereas necrotic cell death is proportionate to severity.

BACKGROUND: Free fibular flap is one of the most useful methods in the hard tissue reconstruction of the maxilla-mandible. Free fibular flap presents some advantages in which the reconstruction of both soft and hard tissues can be done at the same time. It also provides a safe and successful bone graft for the reconstruction, along with a low rate of complications. Despite these advantages and the rarity of a postoperative complication, particularly in oral and maxillofacial surgery procedures, a prolonged operation might exhibit some complications related with rhabdomyolysis. We experienced the rare event of rhabdomyolysis after oral cancer surgery. CASE PRESENTATION: In this article, we report the case of a patient who developed rhabdomyolysis after undergoing free fibular flap surgery. CONCLUSIONS: Despite the advantages of the free fibular flap operation, clinicians must be aware of the risk of complications because there are multiple factors that could result in rhabdomyolysis, such as duration of operation, position of the subject, and pre-existing conditions of diabetes and hypertension. Once the diagnosis of rhabdomyolysis is confirmed, a prompt treatment plan should be made and applied as soon as possible. This will increase the chance of a full recovery for the patient who is exhibiting symptoms of rhabdomyolysis.

PURPOSE: Electrical shock is not always followed by a perfusing rhythm, and multiple shock failure (MSF) is common during CPR. We sought to investigate its risk factors and prognostic implications. METHODS: Adult OHCA patients with emergency department (ED) ACLS attempts were identified from a tertiary hospital OHCA registry extending from 2008 to 2012. Shock failure was defined as any electrical shock attempt not followed by a pulse-generating rhythm. Patients were assigned to one of three groups based on the number of shock failures: 1) MSF: ≥3 electrical shock failures before the first ROSC or CPR termination (if there was no ROSC), 2) early shock success (ESS): pulse-generating rhythm achieved within 3 electrical shock attempts and 3) others: all remaining patients. Baseline characteristics, initial laboratory measurements, and outcomes were compared. RESULTS: A total of 590 patients were included. There was no significant difference in baseline characteristics between the MSF group (n=49) and the early shock success group (n=50) except in its higher proportion of presumed cardiac aetiology. The MSF group showed less severe metabolic acidosis and coagulopathy on ED arrival and better renal function and higher haematocrit and serum albumin levels compared with the ESS group. MSF was associated with less sustained ROSC, but was also associated with more survival discharge and better long-term neurologic outcomes after sustained ROSC. CONCLUSION: MSF may indicate heart-specific problems rather than severe metabolic derangements. Better long-term outcomes can be expected once sustained ROSC is achieved, therefore, this phenomenon warrants more focused research.

BACKGROUND: Bipolar hemiarthroplasty for unstable intertrochanteric fractures in elderly patients is a viable option that can prevent the complications of an open reduction, such as nonunion and metal failure. This study evaluated the clinicoradiological results of cementless bipolar hemiarthroplasty for unstable intertrochanteric fractures in elderly patients. METHODS: Forty hips were followed for more than 2 years after cementless bipolar hemiarthroplasty using a Porocoat(R) AML Hip System. The mean age was 78.8 years and the mean follow-up period was 40.5 months. The Harris hip score and postoperative hip pain were analyzed clinically. The radiological results were assessed using a range of indices. RESULTS: At the last follow-up, the mean Harris hip score was 80.6 points. There were one case of hip pain and one case of thigh pain. Twenty-four cases (60%) showed no decrease in ambulation capacity postoperatively. Radiologically, there were 23 cases (57.5%) of fixation by bone ingrowth and 17 cases (42.5%) of stable fibrous fixation. There were no cases of osteolysis. Eleven cases (27.5%) of new bone formation were found around the stem. All stems were stable without significant changes in alignment or progressive subsidence. CONCLUSIONS: The short-term results of cementless bipolar hemiarthroplasty in elderly patients with unstable intertrochanteric fractures were satisfactory.

Ovarian metastases represent about 3-5% of all ovarian malignancies. Most of these tumors originate in the digestive tract and cholangiocarcinoma rarely involves the ovary. A 60-year-old woman was admitted for the investigation of abdominal distension that had lasted 1 week. One and a half years prior, the patient had undergone choledochal cyst excision, Roux-en Y hepaticojejunostomy and cholecystectomy. Computed tomography scans of the abdomen revealed a papillary mass in the remnant distal common bile duct and enlargement of both ovaries with a huge amount of ascites. An explorative laparotomy disclosed no peritoneal seeding with resectable cholangiocarcinoma and bilateral ovarian mass. Pylorus-preserving pancreatoduodenectomy and bilateral salphingo-oophorectomy with hysterectomy were performed. Histologically, it was a well-differentiated adenocarcinoma and all surgical margins were free of tumor. Both ovarian masses were consistent with metastatic adenocarcinoma from the common bile duct. The patient received six cycles of postoperative adjuvant systemic chemotherapy, dying after 10 months due to pulmonary embolism.

BACKGROUND/AIMS: Treatment of chronic hepatitis B with interferon results in a sustained loss of hepatitis B virus DNA and hepatitis B e antigen (HBeAg) and remission of liver disease only in a proportion of cases. Recently, mutations of hepatitis B virus (HBV) core gene have been reported as being related to the failure of interferon treatment in chronic hepatitis B. This study investigated whether core gene mutations of HBV are related to non-response to interferon therapy and whether the recurrence of HBeAg and HBV DNA in initial responders to interferon therapy is associated with the emergence of HBV core gene mutants. METHODS: The precore/core gene sequence was determined by polymerase chain reaction (PCR) and direct sequencing of PCR product in serum samples obtained before interferon treatment from 10 responders and 10 non-responders to interferon therapy. In addition, precore/core gene sequence was determined in serum samples obtained before interferon treatment and after recurrence from 10 patients who showed recurrence of HBeAg and HBV DNA after initial response to interferon therapy. RESULTS: In samples from 10 responders, there were 7 missense mutations and 71 silent mutations. However, there were 43 missense mutations and 109 silent mutations in samples from 10 non-responders. In samples obtained before interferon treatment from the 10 patients who showed recurrence after initial response, 8 missense mutations and 74 silents mutations were found. The nucleotide sequences from the samples obtained after the recurrence showed 6 silent nucleotide substitutions compared with the sequences from the samples obtained before interferon treatment. CONCLUSIONS: Mutations in the core protein of HBV occur more frequently in non-responders than responders to interferon therapy of chronic hepatitis B and may be a factor responsible for the failure of interferon treatment. The recurrence of HBeAg and HBV-DNA in initial responders to interferon therapy is not associated with the emergence of the HBV core gene mutants.

OBJECTIVES: Ciprofloxacin, one of the most widely used fluoroquinolone, has been used for some abdominal and genitourinary infections in emergency departments (EDs). This investigation was performed to identify the risk factors of inappropriate use of ciprofloxacin in the ED. METHODS: We retrospectively reviewed the medical records of patients who had visited the ED of Seoul National University Hospital from January 2002 to December 2002 and who had been prescribed ciprofloxacin as an initial empirical antibiotic. The appropriateness of ciprofloxacin use was judged according to existing institutional guidelines. RESULTS: Of the total 577 patients (219 males, mean age 53.0+/-17.1; 358 females, mean age 50.3+/-18.7), ciprofloxacin was used appropriately in 289 (50.1%). In the univariate analysis, gender, site of suspected infection, route of administration, and disposition were significantly different between the appropriate and the inappropriate use groups (p<0.005). In multivariate analysis, the adjusted odds ratio for related factors for inappropriate ciprofloxacin use was significantly higher in old age patients (>65 years old) than in younger patients (under 30 years old; OR=2.02, 95% CI=1.01-4.03), in patients having the GI tract infections than in patients having genitourinary tract infections (OR=14.28, 95% CI=8.76-23.29), in patients who were administered orally than intravenously (OR=2.45, 95% CI=2.08-5.71), and in patients who stayed in the ED than in those who were admitted (OR=4.29, 95% CI=1.98-9.34). CONCLUSION: Inappropriate use of ciprofloxacin in the ED is very common. If the emergence of ciprofloxacin resistance is to be avoided, education and efforts for judicious use of ciprofloxacin are warranted.
