Purpose: This systematic review and meta-analysis aimed to compare endoscopy as primary versus secondary prophylaxis to prevent future bleeding in children with esophageal varices. Methods: A systematic literature search using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses method was conducted using the Scopus, PubMed, and Cochrane databases for relevant studies on the outcome of rebleeding events after endoscopy in primary prophylaxis compared to that in secondary prophylaxis. The following keywords were used: esophageal varices, children, endoscopy, primary prophylaxis and bleeding. The quality of eligible articles was assessed using the Newcastle-Ottawa Scale and statistically analyzed using RevMan 5.4 software. Results: A total of 174 children were included from four eligible articles. All four studies were considered of high-quality based on the Newcastle-Ottawa Quality Assessment Scale. Patients who received primary prophylaxis had 79% lower odds of bleeding than those who received secondary prophylaxis (odds ratio, 0.21; 95% confidence interval [CI], 0.07-0.66; I²=0%, p=0.008). Patients in the primary prophylaxis group underwent fewer endoscopic procedures to eradicate varices than those in the secondary prophylaxis group, with a mean difference of 1.73 (95% CI, 0.91-2.56; I²=62%, p<0.0001). Conclusion: Children with high-risk varices who underwent primary prophylaxis were less likely to experience future bleeding episodes and required fewer endoscopic procedures to eradicate the varices than children who underwent secondary prophylaxis.

Variceal bleeding results in significant morbidity and mortality in both children and adults. The guidelines for the management of variceal bleeding are well established in adults but not in children as there have been insufficient pediatric studies of this disorder. In addition, the adult guidelines for treatment of variceal bleeding cannot be applied directly to children as the etiology and natural course of this disease differs between children and adults. Examples of recommended treatments in children include endoscopic variceal ligation as secondary prophylaxis for biliary atresia whereas a meso-Rex shunt operation for extrahepatic portal vein obstruction. In this review, we discuss prophylaxis options and some technical aspects of endoscopic management for variceal bleeding in children.

Purpose: The aim of this study was to investigate prophylactic treatment effects in Korean patients with severe hemophilia A. Methods: A prospective study of 32 severe hemophilia A patients was conducted with the approval of the Institutional Review Board at the Eulji University Hospital. Two patients received primary prophylaxis; whereas, the other 30 patients were divided into 2 groups-secondary prophylaxis (n=15) and on-demand (n=15)-on the basis of their consent for secondary prophylaxis. A 20-25 IU/kg dose of factor VIII concentrate was administered to the primary and secondary prophylaxis group patients every 3 days for 1 year. The prophylactic effect was evaluated by observing changes in the Pettersson scores, annual number of total and joint bleeds, and factor VIII consumption for 1 year. Results: No moderate or severe bleeding was observed, and the Pettersson scores remained unchanged during the prophylaxis period in the patients who received primary prophylactic treatment. After the treatment was changed from on-demand to secondary prophylaxis, the annual number of total and joint bleeds in the secondary prophylaxis group decreased by $64.4%{\pm}13.0%$ and $70.0%{\pm}15.2%$, respectively. The average increase in Pettersson scores within 1 year was $0.5{\pm}0.8$ and $1.3{\pm}1.1$ in the secondary prophylaxis and on-demand groups, respectively. Prophylactic effects were also observed in patients >17 years who had nearly the same initial Pettersson scores. Conclusion: Intermediate-dose prophylactic treatment may delay hemarthropathy progression and prevent its occurrence in Korean severe hemophilia A patients.

Purpose: Clotting factor X deficiency is one of the most uncommon coagulation disorders. The authors describe a case of cleft palate in a patient with a congenital clotting factor X deficiency. Methods: In pediatric patients with a cleft palate, the coagulation problem is more worrisome, because they are more sensitive to blood than adults, and because postoperative bleeding can cause blood ingestion with subsequent vomiting, aspiration, and airway obstruction. To prevent hemorrhagic complications in the described case, fresh frozen plasma (FFP) was administered every 24 hrs from the day before surgery to the second postoperative day. Results: Good hemostasis, normal healing, and no complications was shown postoperatively. Conclusion: The replacement of fresh frozen plasma was useful in the case of congenital clotting factor deficiency for bleeding prophylaxis in cleft palate operation.

Background: The over-prescription of acid-suppressive therapy for the provision of stress ulcer prophylaxis (SUP) in hospitalized patients has been identified in a proceeding study. Objective: This study was conducted to evaluate clinicians' beliefs, knowledge and other factors that influence the over-prescribing of SUP in low-risk, non-intensive care unit (non-ICU) patients. Method: A cross-sectional survey consisting of multiple-choice queries and close-ended questions was distributed to healthcare personnel at a major teaching hospital in Korea. Results: More than half of total respondents reported that they would continue SUP following patients discharge from the ICU (77.8%, 43.5%, and 39.7% in the physician, pharmacist, and nurse groups, respectively). Over 55% of physicians would also initiate non-ICU patients on SUP upon hospital admission, and 42.6% of physicians would even continue prophylaxis post hospital discharge. The mean knowledge score regarding SUP indications and side effects was higher in pharmacists compared to physicians and nurses (12.44, 7.40, and 7.28, respectively; p<0.001). High-prescribing behavior was associated with a prescriber's belief that SUP is effective for preventing bleeding (odds ratio 7.40; 95% confidence interval 1.57 to 31.94; p=0.012). Low knowledge score and computerized order set also showed statistically significant association with the overutilization of SUP.

Patient with congenital heart disease are susceptible to infective endocarditis, and bacteremia following dental procedures may lead to infective endocarditis is these patients. Therefore prophylactic antibiotics are recommended for patients with congenital heart disease who are undergoing dental procedures that are associated with infective endocarditis. In 1997 American Heart Association revised guidelines for a prophylaxis against infective endocarditis. The new American Heart Association recommendations for the prevention of infective endocarditis represent a substantial departure from past guidelines. Major change involve the indications for prophylaxis, antibiotic choice and dosing that may reduce bacteremic risk. Previously, antibiotic prophylaxis was suggested for dental procedures associated with any amount of bleeding. Now only those that are associated with significant bleeding are recommended for prophylaxis as dictated by clinical judgement. Recommended antibiotic prophylaxis regimens now consist of a single preprocedural dose, no second dose is recommended. This report presents three cases of dental treatment of patients with congenital heart disease under the most recent American Heart Association recommendations for antibiotic prophylaxis.

In Western patient populations, the reported incidence of imaging-demonstrated deep vein thrombosis (DVT) after total hip arthroplasty (THA) is as high as 70% without prophylaxis. The reported rates of symptomatic pulmonary embolism (PE) after THA in recent studies range from 0.6% to 1.5%, and the risk of fatal PE ranges from 0.11% to 0.19% in the absence of prophylaxis. Predisposing factors to DVT in western patients include advanced age, previous venous insufficiency, osteoarthritis, obesity, hyperlipidemia, dietary and genetic factors. However, Asian patients who have undergone THA have a strikingly low prevalence of DVT and virtually no postoperative PE. Some authors suggest low clinical prothrombotic risk factors and the absence of some DVT-related genetic factors in Asian patient populations decrease the risk of DVT, PE or both. In Korea, the prevalence of DVT after THA without thromboprophylaxis have ranges from 6.8% to 43.8%, and asymptomatic PE have ranges from 0% to 12.9%; there have been only two reported cases of fatal PE. Deep-wound infections resulting from postoperative hematomas or prolonged wound drainage have been reported with routine thromboprophylaxis. The prevalence of DVT differs varies based on patient ethnicity. Guidelines for the use of thromboprophylaxis were altered and focus on the potential value of outcomes compared with possible complications (e.g., bleeding).

Purpose: The incidence of deep vein thrombosis (DVT) following total hip arthroplasty (THA) without chemoprophylaxis could be as high as 50% in Caucasians. However, according to several subsequent studies, the incidence of venous thromboembolic events (VTE) in Asians was much lower. The routine use of chemoprophylaxis, which could potentially cause increased bleeding, infection, and wound complications, has been questioned in low-incidence populations. The objective of this study is to determine the incidence of VTE after primary THA without chemoprophylaxis in an Asian population using a fast-track rehabilitation protocol and to verify the safety profile for use of 'mechanical prophylaxis alone' in patients with standard risk of VTE. Materials and Methods: This is a retrospective cohort study of 542 Hong Kong Chinese patients who underwent primary THA without chemoprophylaxis. All patients received intermittent pneumatic compression and graduated compression stockings as mechanical prophylaxis. Multimodal pain management was applied in order to facilitate early mobilisation. Routine duplex ultrasonography was performed between the fourth and seventh postoperative day for detection of proximal DVT. Results: All patients were Chinese (mean age, 63.0±11.9 years). Six patients developed proximal DVT (incidence rate, 1.1%). None of the patients had symptomatic or fatal pulmonary embolism. Conclusion: The incidence of VTE after primary THA without chemical prophylaxis can be low in Asian populations when following a fast-track rehabilitation protocol. Mechanical prophylaxis alone can be regarded as a reasonably safe practice in terms of a balanced benefit-to-risk ratio for Asian patients with standard risk of VTE.

Trauma is an important risk factor for a pulmonary thromboembolism, and anticoagulation is essential to prevent deep vein thrombosis (DVT) in patients with trauma. Low-molecular-weight heparin (LMWH) is excreted in the kidney; therefore, using LMWH in patients with renal insufficiency may increase the risk of bleeding complication. The following case describes a 55-year-old traffic accident victim who had massive bleeding and underwent a laparotomy for bleeding control. The patient had acute renal failure, and enoxaparin was administered for the prophylaxis of DVT. Although the patient suffered from serious complications such as pericardial hematoma, the patient recovered without sequellae and was discharged at day 84.

Endoscopic retrograde cholangiopancreatography (ERCP) plays a crucial role in the management of pancreaticobiliary disorders. Although the ERCP technique has been refined over the past five decades, it remains one of the endoscopic procedures with the highest rate of complications. Risk factors for ERCP-related complications are broadly classified into patient-, procedure-, and operator-related risk factors. Although non-modifiable, patient-related risk factors allow for the closer monitoring and instatement of preventive measures. Post-ERCP pancreatitis is the most common complication of ERCP. Risk reduction strategies include intravenous hydration, rectal nonsteroidal anti-inflammatory drugs, and pancreatic stent placement in selected patients. Perforation is associated with significant morbidity and mortality, and prompt recognition and treatment of ERCP-related perforations are key to ensuring good clinical outcomes. Endoscopy plays an expanding role in the treatment of perforations. Specific management strategies depend on the location of the perforation and the patient's clinical status. The risk of post-ERCP bleeding can be attenuated by preprocedural optimization and adoption of intra-procedural techniques. Endoscopic measures are the mainstay of management for post-ERCP bleeding. Escalation to angioembolization or surgery may be required for refractory bleeding. Post-ERCP cholangitis can be reduced with antibiotic prophylaxis in high risk patients. Bile culture-directed therapy plays an important role in antimicrobial treatment.
