Infectious complications such as wound infection and intra-abdominal abscess are rarely fatal, but perplexing to both patients and surgeons, and still remain asserious problem after appendectomy in about 5% of the patients. To be helpful to reduce post-appendectomy complications, authors retrospectively analyzed 229 cases of appendectomy performed during the period of one year, from January 1 through December 31, 1995, to find out contributing factors to the post-appendectomy infectious complications such as wound infection or intra-abdominal abscess. The results were as follows. 1) Infectious complications are more common in patients with four or more days of symptom. 2) Infectious complications are more common in patients with complicated appendicitis such as gangrenous or perforated appendicitis. 3) Preoperative antibiotics are helpful to prevent infectious complications in cases of complicated appendicitis. 4) There is no difference in the incidence of infectious complications between the immediate operations and overnight delayed operations in patients who were admitted in the late evening or at night. 5) There is no difference in the incidence of infectious complications between operators: staff surgeons who exclusively operated on patients with complicated appendicitis and residents(with or without supervision of staff surgeons) who mostly operated on patients with simple appendicitis. This means technical superiority has its role in preventing infectious complications. Early diagnosis and operation before the gangrenous change or perforation are warranted. Preoperative antibiotics are effective in cases of complicated appendicitis, but not in cases of simple appendicitis. But the lack of objective criteria to decide complicated appendicitis before the operation remains problem, and prospective study to solve this problem is needed. Technical perfectness is required to protect the wound and to remove the appendix without contamination. Preventive measures are also important to prevent the infectious complications in cases of inevitably contaminated wounds or inta-abdominal spaces.

OBJECTIVE: To determine whether cyclooxygenase (COX)-1 and COX-2 are expressed differentially during the whole gestational period in the pregnant human uterine cervix and if they are involved in the process of labor. METHODS: Nine patients were matched for obstetrical history and maternal age were divided into an abortion group who aborted between 13 and 16 weeks(n=3), a preterm group who delivered between 20 and 37 weeks(n=3), and a term group who delivered between 37 and 42 weeks of gestation(n=3). Immediately after vaginal delivery cervical biopsy samples were obtained and immunohistochemically stained for COX-1 and COX-2 and the degree of staining was evaluated by H-scoring system. RESULTS: Expression of COX-1 and COX-2 was found in epithelial and stromal cells of uterine cervical tissues of preterm and term group. The immunohistochemical expression of COX-1 and COX-2 was strongest in the term group compared to the preterm group in stromal cells(HSCORE : 2.0 vs. 4.0 ; 2.0 vs. 3.0), and in epithelial cells(HSCORE : 1.0 vs. 3.0 ; 1.0 vs. 3.0). CONCLUSION: Although small amount of the groups were investigated, in the pregnant human uterine cervix, COX-1 and COX-2 are found to be expressed, and both shows the strongest expression in term cervical tissue. It is suggested that the uterine cervix, under the control of prostaglandins, is actively involved in the process of labor, and it is thought that the role of COX-1 and COX-2 is more important in parturition process with advancing gestational age.

BACKGROUND: In athlete's heart, functional and structural alteration are main features. We studied electrocardiograms(ECG's) and echocardiograms(UCG's) in soccer players before and after intensive training. METHODS: Fifteen soccer players with the mean age and career of 19.3 and 8.5 years,respectively,underwent intensive training for 5-5.5 months, which included running of 2 km daily during the last 2-2.5 months. Comparisons of ECG's and UCG's recorded before and after the training were made. RESULTS: The major abnormal finding in pre-training ECG's was high voltage being seen in 40% of the cases, and in UCG's left ventricular(LV) dilatation and/or hypertrophy or asymmetrical septal hypertrophy(ASH) were noted in approximately 80% of the cases. The incidences of these finding after the intensive training were essentially unchanged, and the mean of pre-and post-training fractional shortening(FS) and LV and left atrial dimensions were similar. The high voltage in ECG's showed no close correlation with LV dilatation or hypertrophy on UCG's. After the training, however, the mean values of the thickness of LV posterior wall and ventricular septum along with LV mass were significantly increased, and the right ventricular dimension was significantly decreased. CONCLUSIONS: The most frequent finding in ECG's and UCG's in soccer players, before and after intensive training,were high voltage, LV dilatation and /or hyperophy with or without ASH. The intensive training of 5-5.5 months duration caused no change in F8,but caused significant increase in the thickness of LV posterior wall and ventricular septum, and LV mass.

BACKGROUND: A rehabilitation hospital has the characteristics of longer hospital stay, a variety of medical and paramedical personnels involved in treatment, and more probability of the primary care giver being a nonmedical person. The purpose of this study is to describe the characteristics of nosocomial infection in a rehabilitation hospitals METHODS: Surveillance was done in a rehabilitation hospital affiliated university hospital from June to August 1996, May to June 1997, and July to September 1999. Nosocomial infection was investigated by an infection control practitioner (JCP) according to the Center for Disease Control and Prevention (CDC)'s definitions visiting the rehabilitation wards regularly. RESULTS: The overall NI rates were 3.83 in 1996, 4.42 in 1997 and 1.91 in 1999 per 1,000 patient days, and the urinary tract infection (UTI) rates were 2.82 in 1996, 2.87 in 1997 and 1.07 in 1999 per 1,000 patient days. Both of overall NI rate and UTI rate in 1999 decreased significantly compared with that in 1996 and 1997 (P<0.001). Comparing the ward specific NI rate, the average NI rate of the spinal cord injury ward was the highest (5.67 per 1,000 patient days) and that of the pediatric rehabilitation ward was the lowest (0.83 per 1,000 patient days). UTI constituted of the largest proportion of NIs. The distribution of UTI showed a decreasing tendency from 73.47% in 1996 to 56.00% in 1999, but the distribution of gastrointestinal infection showed an increasing tendency from 4.08% and 5.40% in 1997 and 1996 to 24.00% in 1999. The commonly isolated organisms were E. coli (33.63%), Enterococcus spp. (12.73%) and C. difficile (7.27%). It reflected that the main infection was UTI. CONCLUSION: The main NI in rehabilitation hospital was the UTI. It means that the infection control program of rehabilitation hospital should be focused on the control of UTI. Surveillance in the rehabilitation hospital enabled us to describe the characteristics of nosocomial infection in the rehabilitation hospital. NI rate was decreased through continuous communications and educations with factual datum and involvement of various medical and paramedical personnels. These results show that NI surveillance is crucial for an efficient infection control program.

PURPOSE: Anal diseases are a common complication among patients with leukemia, and the perianal abscess may prove to be the most fatal among anal diseases. We report here the prevalence, the treatment methods, and the prognosis for anal diseases among patients with leukemia. METHODS: Among the 310 patients who were diagnosed with and treated for leukemia between October 1999 and September 2000, we investigated the medical records of 53 patients with complications due to anal diseases. RESULTS: Among the 310 patients with leukemia, 53 (17.1%) reported anal diseases. There were 30 patients with hemorrhoids, 15 patients with a perianal abscess, 3 patients with an anal fistula, 3 patients with a fissure and 2 patients with hemorrhoids and fistulas. Anal pain was the most common complaint. Conservative treatment improved the symptoms in 42 patients (79.2%) while surgery was necessary in the remaining 11 patients (20.8%). A hemorrhoidectomy was undertaken in 4 patients, a drainage procedure in 4 paients, and a fistulotomy in 3 patients. Throughout the study period, 6 patients died (11.3%), 3 of them with perianal abscesses. Among the 15 patients with a perianal abscess, 13 showed fever (87%), and 9 patients underwent drainage (4 surgical drainages and 5 natural drainages). E. coli was the most commonly cultured organism. CONCLUSIONS: The incidence of anal diseases in patients with leukemia was high. Nonsurgical methods were sufficient for hemorrhoids and fistulas. For a perianal abscess, drainage should be undertaken when abscess formation is evident. When abscess formation is not evident, medical treatment is the primary modality, and surgery should be considered only when medical treatment fails to improve or worsens the patient's condition, but the prognosis is poor.

Breast cancer is a common malignancy in women and metastasizes to the liver, the lung, the brain, and the bone, but metastasis to the colon is rare. We describe a 58-year-old woman with colon metastasis of breast cancer. She was diagnosed with right colon cancer, and during investigation for colon cancer, we found a breast cancer. She received a palliative right hemicolectomy due to obstruction before chemotherapy. The histology of the tissue taken from the right colon was shown to be the same as that of the left breast mass. This is a case of colonic metastasis from breast cancer and we report this case with a review of literature.

PURPOSE: Although the reported failure rate of the transobturator tape procedure(TOT) is low, recurrence after this procedure have been reported, and no standard treatment has yet been established for the recurrence. We compared a shortening of the previously implanted tape with a repeat tension-free vaginal tape(TVT) procedure after a failed TOT procedure. MATERIALS AND METHODS: We enrolled eighteen women(mean age: 54.38+/-9.15 years, range: 38-72) who underwent shortening of the previously implanted tape or they underwent a repeated TVT procedure due to persistent or recurrent SUI. Of the 18 women, 10 patients underwent shortening of implanted tape and the others underwent repeat TVT. All the patients were evaluated preoperatively with a detailed history, pelvic examination, urinalysis, voiding diary and urodynamic study that included the Valsalva leak point pressure(VLPP). The postoperative outcomes were assessed by a review of admissions and the medical charts. RESULTS: The mean interval from first surgery to recurrence was 6.88+/-2.61 months for Monarc, 12 months for TVT-O and 4.71+/-2.42 months for T-sling. Of the 10 patients who underwent shortening of the implanted tape, 7(70%) patients were cured and the others failed. Of the 8 patients who underwent repeat TVT, 7(87.5%) patients were cured and one was significantly improved. The success rate is significantly higher in the repeated TVT group(p<0.05). CONCLUSIONS: Both a shortening of the previously implanted tape and a repeated TVT procedure are safe, effective, viable options in the event of initial TOT sling failure. However, the success rate of the repeated TVT group is higher than that of the shortening of implanted tape group, especially for patients with an internal sphincteric deficiency. Therefore, a repeated TVT procedure is a first option in the event of initial TOT sling failure.

PURPOSE: The purpose of this study is to investigate the factors that predict using mechanical ventilation for patients with organophosphate intoxication. METHODS: We retrospectively reviewed the medical records of 111 patients with acute organophosphate intoxication and who were treated in our emergency center from January 2000 to December 2008. We compared the toxicologic characteristics, the laboratory findings and the APACHE II scores between the Mechanical Ventilation group (MV group) and the non-Mechanical Ventilation group (the non MV group). RESULTS: Sixty three patients were in the MV group and 48 patients were in the non MV group. In the MV group, the patients had an older age (p<0.001), a larger amount of ingestion (p<0.001), a lower initial serum cholinesterase level (p=0.003), a higher APACHE II score (p<0.001) and they ingested a more toxic agent (p=0.001). There were no significant differences in gender, the type of visit and the arrival time between the MV group and the non MV group. CONCLUSION: We suggest that the patient's age, the amount of organophosphate ingestion, the toxicity of the agent, the initial serum cholinesterase level and the APACHE II score are important factors to determine if mechanical ventilation will be applied for patients with organophosphate intoxication.
