Injury of diaphragm mainly occur in penetrating, crush and blunt injuries to the lower chest or upper abdomen, and it is most often secondary to automobile accidents. Diaphragmatic rupture is most frequent in blunt chest trauma and the rate is below 1% of them. Traumatic rupture of the diaphragm is responsible for the herniation of abdominal viscera. Physical finding and radiographic sign of diaphragmatic hernia is nonspecific and misreading. Therefore, the diagnosis of traumatic rupture of diaphragm may be difficult during the early period after the injury, especially when clinical features are dominated by associated injuries. Emergency surgical management is necessary when it is complicated with serious complication. We experienced the case of traumatic diaphragmatic hernia detected after the operation of femur fracture. The patient was injured by motor vehicle accident 6 days before the operation of the femur fracture. There was no specific symptom and sign and the manifestation of the diaphragmatic hernia. in radiographic studies until operation of the femur fracture was done. Diaphragmatic hernia was confirmed by chest X-ray and arterial blood gas analysis after operation of the femur fracture. The repair of the diaphragmatic hernia was directly performed after the diagnosis. The prognosis was favorable, and she was discharged to ward from intensive care unit after 1 day of operation. We must consider the possibility of traumatic diaphragmatic hernia in the patient who have the history of blunt chest or abdominal trauma.

One of the goals of anesthesia is complete, comfortable and rapid recovery without sequelae from anesthesia. We compared the recovery pattern between anesthesia with propofol and thiopental/isoflurane. The fifty patients undergoing emergency appendectomy were allocated randomly to receive one of the anesthesia with propofol or thiopental/isoflurane. All of the patients were also given fentanyl, atracurium in equivocal dosage per weight and 50% N2O. Group 1(patient No; 25) was received anesthesia with fentanyl, atracurium, N2O and continuous injection of 6~12 mg/kg/hour of propofol. Group 2(patient No; 25) was received anesthesia with thiopental, fentanyl, atracurium, N2O and 1~2 MAC(minimal alveolar concentration) of isoflurane. We studied the duration of return of self respiration from discontinuation of anesthetics and recovery pattern in time sequence. The results were as following; The group 1 compared with group 2 at early recovery phase. 1) The duration of return of self respiration from discontinuation of anesthetics retured more rapid. 2) Emergence time was more rapid. 3) Postoperative sequelae(nausea, vomiting, sedation, drowsiness, memory dysfunction, pain) rate was less severe. But at recovery phase after 24 hours, there were no significant difference in postoperative sequelae and recovery condition in both groups. Therefore, we concluded that propofol is better than thiopental/isoflurane for anesthesia of emergency appendectomy in view of early recovery pattern.

BACKGROUND: The perfect preanesthetic medication and its ideal route of administration are still debated. Transmucosal administration of midazolam has been of interest because of the rapid, reliable onset of action, predictable effects and avoidance of injections. Because many medications are well absorbed from the mucosa, we conducted a randomized, prospective, blinded study to compare acceptance and efficacy of intranasal and sublingual administration of midazolam as a preanesthetic medication in children. METHODS: One hundred twenty eight patients aged 0.5-12year were stratified by age: 38 infants and toddlers, 0.5-3yr; 48 preschoolers, 3.1-7yr; and 42 school age, 7.1-12yr. They were randomized to received 0.2 mg/kg of midazolam in the nose or under the tongue. Hemoglobin oxygen saturation by pulse oximetry and sedation score were recorded before drug administration, at 2.5min intervals for 15min, at separation from parents and during induction with enflurane in O2. Retention time of sublingual drug and duration of crying were recorded. RESULTS: The incidence of crying at the time of administration of midazolam was greater following intranasal compared with sublingual administration(60% vs 17%, p<0.05). Within age groups, only infants and toddlers showed a significant difference in the incidence of crying between treatment groups. Significant changes in sedation occured in both groups from 2.5min after administration. CONCLUSIONS: Sublingual midazolam is better accepted than intranasal midazolam as a preanesthetic sedative in children.

PURPOSE: To evaluate the side effects, pattern of failure, and survival rate according to the sequence of postoperative adjuvant radiotherapy and chemotherapy, patients with stages II and lll rectal cancer who had undergone curative resection were randomized to early radiotherapy group (arm I) or 'late radiotherapy group (arm II)', then we intend to determine the most effective sequence of the radiotherapy and chemotherapy. MATERIALS AND METHODS: From January 1996 to March 1999, 3 13 patients with curatively resected stages II and III rectal cancer have been randomized to early' or late radiation therapy group and recei ved combined chemotherapy (5-FU 375 mg/m/day, leucovorin 20 mg/m, IV bolus daily D1-5, 8 cycles) and radiation therapy (whole pelvis with 45 Gy/25 fractions/5 weeks). Arm I received radiation therapy from day 1 with first cycle of chemotherapy and arm II received radiation therapy from day 57 with third cycle of chemotherapy after completion of first two cycles. Preliminary analysis was performed with 228 patients registered up to Jun 1998. Two out of the 228 patients were excluded because of double primary cancer. Median follow-up period was 23 months. RESULTS: Local recurrence occurred in 11 patients (9.7%) for arm I and 9 patients (8%) for arm II. There was no significant difference between both groups (p=0.64). However, distant metastasis was found in 22 patients (19.5%) for arm I and 35 patients (31.0%) for arm II and which showed statistically significant difference between the two groups (p=0.046). And neither 3-year disease-free survival (70.2% vs 59.2%, p=0.2) nor overall survival (89.4% vs 88.0%, p=0.47) showed significant differences. The incidence of leukopenia during radiation therapy and chemotherapy was 78.3% and 79.9% respectively but leukopenia more than RTOG grade 3 was only 2.1% and 6.0% respectively. The incidence of diarrhea more than 10 times per day was significantly higher in the patients for arm I than for arm II (71.2% vs 4 1.6%, p=0.02) but this complication was controlled with supportive cares. CONCLUSION: Regardless of the sequence of postoperative adjuvant radiation therapy and chemotherapy a fter curative resection for rectal cancer, local recurrence rate was low with combined chemoradiotherapy. But distant metastasis rate was lower in early radiation therapy group than in late radiation therapy group and the reason is unclear. Most patients completed these treatments without severe complication, so these were thought to be safe treatments but the treatment compliance should be improved.

Anal cancer is a relatively rare disease to supply consistent therapeutic modality. We analysed 18 anal cancer patients treated from 1989 to 1996 at the Department of Surgery, Asan Medical Center, to evaluate two categories of the treatment e.g. initial surgery followed by radiochemotherapy and radiochemotherapy Preceding surgery. The aim of this study is to evaluate the advantage and pitfall of both therapeutic options. Among 18 patients presenting with carcinoma of the anus, the dominant histologic type was squamous followed by cloacogenic and verrucous carcinoma, 72%, 17%, 11% respectively According to the staging system of AJCC/UICC, T1 and T2 were 12 patients, NO were 7 patients. According to the treatment options, abdominoperineal resection preceding radiochemotherapy were performed in 8 patients, Whereas surgery after radiochemo-therapy were in 10 patients. Among the 8 patient with prior surgery, two patients developed recurrent disease and one patient was dead. Among the 10 patient with prior radiochemotherapy, two patients developed recurrent disease and two patients were dead. Histological differentiation of squamous cell carcinoma was significantly related with survival. The metachronous lymph nodes metastasis showed poorer prognosis than the synchronous metastasis. Radiochemotherapy shoud be considered as primary therapy of anal cancer that obviated wide excision sacrificing anorectal function.

PURPOSE: Selecting the best surgical approach for treating complete rectal prolapse involves comparing the operative and functional outcomes of the procedures. The aims of this study were to evaluate and compare the operative and functional outcomes of abdominal and perineal surgical procedures for patients with complete rectal prolapse. METHODS: A retrospective study of patients with complete rectal prolapse who had operations at a tertiary referral hospital and a university hospital between March 1990 and May 2011 was conducted. Patients were classified according to the type of operation: abdominal procedure (AP) (n = 64) or perineal procedure (PP) (n = 40). The operative outcomes and functional results were assessed. RESULTS: The AP group had the younger and more men than the PP group. The AP group had longer operation times than the PP group (165 minutes vs. 70 minutes; P = 0.001) and longer hospital stays (10 days vs. 7 days; P = 0.001), but a lower overall recurrence rate (6.3% vs. 15.0%; P = 0.14). The overall rate of the major complication was similar in the both groups (10.9% vs. 6.8%; P = 0.47). The patients in the AP group complained more frequently of constipation than of incontinence, conversely, in the PP group of incontinence than of constipation. CONCLUSION: The two approaches for treating complete rectal prolapse did not differ with regard to postoperative morbidity, but the overall recurrence tended to occur frequently among patients in the PP group. Functional results after each surgical approach need to be considered for the selection of procedure.

Mycoplasma pneumoniae is a common cause of community-acquired respiratory infection in children. Through uncertain pathologic mechanisms, which most probably involve immunologically cell-mediated tissue damage, it causes life-threatening disease on rare occasion. We herein report a case of M. pneumoniae pneumonia, with encephalopathy followed by multiple organ failure in a previously healthy boy. Despite of intensive therapies with intravenous antibiotics, corticosteroid, hemodiafiltration, and transfusion, his neurologic and pulmonary sequales have remained. In most cases M. pneumoniae pneumonia are usually self- limiting with benign outcome. Even in healthy individual, however, it can manifest itself with a fulminant course and multi organ failure.

PURPOSE: This study was aimed to analyze the clinical characteristics of patients with acute interstitial pneumonia who had presented similar clinical patterns from March to June, 2006 and to describe our experience of treatment and to identify risk factors associated with prognosis. METHODS: The clinical characteristics, radiologic and histopathologic findings and response to steroids of 15 patients (non-survival group [n=7] and survival group [control, n=8]) with acute interstitial pneumonia were investigated through the review of medical records. RESULTS: The mean age of the patients was 26 (range: 3-48) months. Cough, cyanosis and fever were frequent symptoms. The most frequent radiologic findings on admission were pneumomediastium and extensive ground glass opacity. Surgical lung biopsy was performed on 8/15 (53.3%) patients and diffuse alveolar damage was found. Mechanical ventilation was applied for 9/15 (60.0%) patients for 40 (range: 1-99) days. Five patients in survival group received steroid treatment and 7 patients in non-survivial group (P=0.20). One patient in survival group received steroid pulse treatment and 4 patients in non-survival group (P=0.12). Seven patients died all of respiratory failure. The survival rate was 53.4%. CONCLUSION: The patients with acute interstitial pneumonia which occurred on spring 2006 showed high mortality because of rapidly and extensively progressing pulmonary fibrosis and air leakage. Therefore, we should consider surgical lung biopsy and steroid application earlier. We should recognize this acute interstitial pneumonia occurring on spring in domestics and need to investigate the cause and treatment in large scale.

Objective:
Adequate methods of combining T2-weighted imaging (T2WI) and diffusion-weighted imaging (DWI) to assess complete response (CR) to chemoradiotherapy (CRT) for rectal cancer are obscure. We aimed to determine an algorithm for combining T2WI and DWI to optimally suggest CR on MRI using visual assessment.
Materials and Methods:
We included 376 patients (male:female, 256:120; mean age ± standard deviation, 59.7 ± 11.1 years) who had undergone long-course CRT for rectal cancer and both pre- and post-CRT high-resolution rectal MRI during 2017– 2018. Two experienced radiologists independently evaluated whether a tumor signal was absent, representing CR, on both post-CRT T2WI and DWI, and whether the pre-treatment DWI showed homogeneous hyperintensity throughout the lesion. Algorithms for combining T2WI and DWI were as follows: ‘AND,’ if both showed CR; ‘OR,’ if any one showed CR; and ‘conditional OR,’ if T2WI showed CR or DWI showed CR after the pre-treatment DWI showed homogeneous hyperintensity. Their efficacies for diagnosing pathologic CR (pCR) were determined in comparison with T2WI alone.
Results:
Sixty-nine patients (18.4%) had pCR. AND had a lower sensitivity without statistical significance (vs. 62.3% [43/69]; 59.4% [41/69], p = 0.500) and a significantly higher specificity (vs. 87.0% [267/307]; 90.2% [277/307], p = 0.002) than those of T2WI. Both OR and conditional OR combinations resulted in a large increase in sensitivity (vs. 62.3% [43/69]; 81.2% [56/69], p < 0.001; and 73.9% [51/69], p = 0.008, respectively) and a large decrease in specificity (vs. 87.0% [267/307]; 57.0% [175/307], p < 0.001; and 69.1% [212/307], p < 0.001, respectively) as compared with T2WI, ultimately creating additional false interpretations of CR more frequently than additional identification of patients with pCR.
Conclusion
AND combination of T2WI and DWI is an appropriate strategy for suggesting CR using visual assessment of MRI after CRT for rectal cancer.
