Clostridium difficile-associated diarrhea (CDAD) is common among hospital-acquired bacterial diarrhea, its mortality and morbidity show an increasing trend in recent years. Improper antimicrobial drug use is one of the key reasons. Adequate hand hygiene of healthcare workers, thorough disinfection of hospital environment, and appropriate isolation of patients are effective measures to prevent the outbreak of hospital-aquired CDAD.

PURPOSE: Despite advances in infection control practices, Surgical Site Infections (SSIs) remain a substantial cause of morbidity and mortality among hospitalized patients. This study was undertaken to determine prospectively the incidence of postoperative wound infections in surgical patients and to identify the risk factors associated with the development of wound infections. METHODS: Prospective data on 761 surgical operation patients in the department of surgery at Ewha Womans University Mokdong Hospital were collected over a 7 month-period from May 1, to December 31, 2001. The Centers for Disease Control and Prevention (CDC)'s definitions of surgical wound infections were used. RESULTS: A total of 761 patients were observed over 30 days. The overall incidence of wound infection was 2%. SSIs were significantly associated with the degree of wound contamination (P=0.0004). The infection rate increased as the degree of wound contamination increased from clean (1.4%) through clean-contaminated (1.8%) and contaminated (1.8%), to dirty- infected wound (12.7%). The infection rate was related with the American Society of Anesthesiologists (ASA) preoperative assessment score (P=0.00153). There were no SSIs from laparoscopic surgery. The duration of operation was not associated with an increase in wound infections. Enterococcus faecium and Staphylococcus aureus were the most frequently isolated organisms. Three out of the five (60%) cases of E. faecium were vancomycin-resistant enterococci (VRE) and all of three cases of S. aureus were methicillin- resistant Staphylococcus aureus (MRSA). CONCLUSION: This study confirms that the degree of wound contamination is a significant preoperative risk factor for SSI. Many antibiotic-resistant bacteria such as MRSA and VRE were isolated. Accordingly, infection control practitioners need to consider this risk factor in the design of effective infection control strategies. There should be another safe and feasible option available for the treatment of selective patients.

During the second half of the 19th century many operations were developed after anesthesia was introduced but advances were limited for many years because of the high rate of infection and the high mortality rate that followed infections. After the introduction of the principle of antisepsis, postoperative infectious morbidity decreased substantially. With the introduction of antibiotic therapy in the middle of the 20th century, a new adjunctive method to treat and prevent surgical infections was discovered. However, not only have postoperative wound and hospital required infections continued, but widespread antibiotic therapy has often made prevention and control of surgical infections more difficult. Based on National Nosocomial Infection Surveillance (NNIS) system reports, SSIs (Surgical Site Infections) are the third most common nosocomial infection, accounting for 14% to 16% of all nosocomial infections among hospitalized patients. It is also a significant source of postoperative morbidity, resulting in increased hospital length of stay and increased cost. Determination of risk factors for the development of SSI has been a major focus of surgical research. To reduce the rate of SSIs we have to eliminate risk factors of SSIs and keep a continuous surveillance with feedback of information to surgeons and other relevant staff. A successful SSI surveillance program includes standardized definition of infection, effective surveillance method, and stratification of the SSIs rates according to risk factors. Because SSIs may be the most preventable of nosocomial infections, health care facilities should make special efforts to reduce the risk of development of these surgical complications. The evaluation of infection control programs and the development of more effective infection control strategies should be established and surgeons should be more concern about SSI control.

Puerperal sepsis is one of the leading causes of maternal morbidity and mortality worldwide. Postpartum pelvic infections can cause various complications, including wound infections and necrotizing fasciitis. Several microorganisms are known to cause such infections; however, no study has reported on Staphylococcus caprae, a coagulase-negative staphylococcus that is isolated frequently from animals and infrequently from human specimens, as a causative agent. Here, we report a rare case of septic shock complicated by necrotizing fasciitis after a cesarean section. This is the first report of a human isolate of S. caprae in association with puerperal sepsis and necrotizing fasciitis.

BACKGROUND: Lymphocytopenia is a common finding in critically ill patients while lymphocyte depletion in critically ill patients is presumed to have little clinical significance. However, a total lymphocyte count has been reported to provide prognostic information in surgical patients. The aim of this study was to evaluate the association of a total lymphocyte count (TLC) with a prognostic criterion in critically ill patients. METHODS: The patients were divided into three groups according to their TLC on admission to intensive care unit (ICU) (Group 1: TLC > 1.0 x 10(9)/L, Group 2: 0.7 x 10(9)/L < TLC < 1.0 x 10(9)/L, and Group 3: TLC <0.7 x 10(9)/L). Outcomes examined were patients' in-hospital mortality, length of hospital stay and incidence of infection. RESULTS: Patients with a TLC less than 0.7 x 10(9)/L (Group 3) had an infection twice (32% VS 15%) as often as those with a TLC more than 0.7 109/L (Group 1 2). But, in the hospital stay and mortality, there was no significant difference among the groups. CONCLUSIONS: TLC is very useful indicator in critically ill patients with a high risk of hospital infection on ICU admission.

The concepts of systemic inflammatory response syndrome (SIRS) and scoring system were defined by the journal of Bone in 1992. SIRS was described as occurrence of two or more clinical criteria in four ones (fever or hypothermia, tachypnea, tachycardia, and leukocytosis). An early diagnosis and estimation of systemic inflammation in patients is helpful for treatment selection. This paper reviews the application of SIRS scoring system, which has been extensively validated for large groups of critical care patients with severe injury and critical surgical diseases. Recent studies have documented SIRS score as a significant predictive parameter of adverse outcome in critical care patients. Furthermore, some studies also give us a suggestion on how to reduce the overload systemic response.

Deep sternal wound infection (with or without acute mediastinitis) is a serious complication of open heart surgery, with high rates of associated morbidity and mortality, and prolonged hospitallization. The result of treatment largely depends on timely diagnosis and appropriate surgical management. Postoperative deep sternal wound infections in 4 cases were successfully treated with extensive debridement, pressurized jet irrigation with antibiotic solution, sternal refixation by Robicsek method, and dilute antibiotic irrigation via irrigation-suction system. We report 4 cases with review of articles.

Vibrio vulnificus infections occur between May and October, and most often involve men over age 40. V. vulnificus has been linked to two distinct syndromes: primary sepsis and primary wound infections. Primary sepsis occurs most commonly in patients with antecedent liver disease such as cirrhosis. Mortality approaches about 50 percent, with most deaths due to uncontrolled sepsis. We experienced a case of septicemia without dermatologic lesion by serovar type O1 V. vulnificus, and reported this case with a review of literature.

Although the incidence of mediastinal wound infection in patient undergoing median sternotomy for cardiovascular surgery is relatively low(less than 1%), it is not only a devastating and potentially life-threatening complication but also associated morbidity, mortality and cost are unacceptably high. During the past few decades various methods had been applied for the treatment of postoperative mediastinitis. Currently, chest wall reconstruction by using muscle flaps-especially pectoralis major muscle and rectus abdominis muscle are commonly selected for the reconstruction after wide debridement has become widely accepted. We performed bilateral pectoralis major-rectus abdominis muscles in-continuity bipedicle flap to overcome the limit of each flap for reconstruction of sternal defects in 17 patients. We analyzed the results of the surgery. Recurrent infection developed in 17.6% of cases and abdominal herniation was observed in one patient. There was no postoperative hematoma or death. We conclude that this flap is very valuable in reconstruction of the anterior chest wall defect caused by post-sternotomy infection because it provides sufficient volume to fill the entire mediastinum, and the complication rate compares favorably to that of other methods.
