BACKGROUND:We performed this study to determine the influence of the administration of pneumoperitoneum on the blood flow of the thoracoabdominal aorta during laparoscopic cholecystectomy (LC). METHODS: Ten patients for LC were enrolled in this study. Anesthesia was performed with propofol, fentanyl and rocuronium. Pneumoperitoneum was made by CO2 gas intraperitoneal instillation at an intraperitoneal pressure of 10-12 mmHg. Peak velocity of blood flow in the systolic phase (PV), mean acceleration of blood flow from the start of systole (MA) and systolic flow time corrected for heart rate (FTc), measured by esophageal doppler monitoring (EDM), and heart rate (HR) and mean brachial BP (MBP) were measured 1, 5 and 10 min after the institution of pneumoperitoneum, (T1, T5 and T10) and compared with those before the institution of pnuemoperotoneum (T0). LC was started after recording all measurements and a position change to the reverse-Trendelenberg position. RESULTS: PV, MA, FTc and HR showed no significant change throughout this study, but MBP at T5 and T10 (110.1 +/- 18.5 mmHg and 107.8 +/- 10.4 mmHg) were significantly higher than at T0 (84.9 +/- 12.9 mmHg) (P = 0.002 and 0.005 respectively). CONCLUSIONS: The administration of pneumoperitoneum neither changed nor interferenced with abdominal aortic blood flow.

We report a case of pseudoaneurysm formation after aneurysmal clipping. An aneurysm, which was located on the beginning of orbitofrontal artery, was clipped and wrapped with Surgicel(R) and fibrin glue. Four weeks later, an enlarged aneurysm was detected at the same site on postoperative angiography. We could not find a new aneurysm in the second operation except inflated wrapping region. And clip had been slipped from the original aneurysmal neck. So we concluded that a new aneurysm was a pseudoaneurysm made with surgicel and fibrin glue. And it had been formed from continuous minor leakage caused by slipped clip.

Glassy cell carcinoma is a histologic subtype of cervical cancer with distinct pathologic features and it has an aggressive biologic course. It was first described by Glucksmann and Cherry in 1956 as a poorly differentiated adenoquamous carcinoma and commented on its poor prognosis, unresponsiveness to traditional modes of therapy, and often associated with pregnancy. The characteristic histologic features are defined as follows: 1) cells with a moderate amount of cytoplasm resembling ground glass, 2) a fairly distinct cell membrane that stains with eosin or PAS, 3) large nuclei with prominent nucleoli. We present two cases of glassy cell carcinoma of the cervix successfullyl treated by neoadjuvant chemotherapy and radical hyterectorny, with a brief review of literatures.

Emergency surgical repair for acute traumatic aortic ruptures has been associated with a high peri-procedural mortality rate. Endovascular stent-grafting, as a less invasive procedure, has shown encouraging results. This report describes a patient with a short landing zone, who was treated by transposing the supra-aortic branch without sternotomy, followed by covered stent-grafting with an extended proximal bare portion to enhance fixation.

Dengue fever is an acute febrile disease that is caused by a mosquito-borne flavivirus. It has become a major infectious disease threat in tropical and subtropical areas. In Korea, travel-associated dengue fever is increasing. Thirty-five Koreans went to Sri Lanka to do volunteer activities. Eight of the volunteers developed fever, myalgia, and rash; they were diagnosed with dengue fever. Two patients had macular hemorrhages and edema with no ophthalmic symptoms. The maculopathy caused by the dengue fever improved without specific treatment.

The causes of aortic dissection are usually hypertension, connective tissue disease such as Marfan syndrome, congenital valvular abnormality such as bicuspid aortic valve, iatrogenic injury, pregnancy and drugs. Previous studies have shown that 50% of all dissections in women less than 40 years age were associated with pregnancy. Almost all aortic dissections during pregnancy occur during the third trimester or during labor and delivery. Marfan's syndrome is a particularly important predisposing factor for aortic dissection during pregnancy. We report here on a case of surgical treatment for acute type II aortic dissection in a Marfan syndrome patient who was 24 weeks pregnant, and we include a review of literature.

PURPOSE: Consensus guidelines clearly define how cardiopulmonary resuscitation (CPR) is to be performed, but the parameters of CPR in actual practice are not routinely measured, nor is the quality known. We sought to investigate the actual quality of CPR performed by trained hospital staffs and to determine whether metronome guidance improved the quality of CPR. METHODS: A prospective study was performed on 26 out of hospital cardiac arrest patients who received CPR at an emergency department (ED). In the ED, resuscitation efforts were recorded by using a camcorder. Using the recorded data, we analyzed the parameters of CPR quality such as ventilation and chest compression rates. RESULTS: In the 26 cardiac arrests, the first nine cases constituted group I. The subsequent nine cases, after the rescuers had been re-trained to provide CPR according to the guideline, constituted group II. The final eight cases after the rescuers had been trained to use metronome guidance constituted group III. The average ventilation rate in group I was 30.7 ventilations/min. Although the average ventilation rate in group II was lower than that of group I, it was still higher than the recommended rate. After metronome guidance, the ventilation rate was significantly reduced and approached to the rate of the present guideline. The average chest compression rate in group I was higher than the rate recommended in the present guideline and was significantly reduced after metronome guidance. CONCLUSION: We strongly believe that further study should be performed to consider the survival benefit of good-quality CPR. Devices providing feedback to alert rescuers may be useful for improving the quality of CPR.

BACKGROUND: This study evaluated the accuracy of smoking habit from the data obtained from the medical records of lung cancer patients against the data obtained form face-to-face interview questionnaires METHODS: The smoking habits of 225 lung cancer patients were categorized into never smoked, ex-smoker and current smoker in face-to-face interview questionnaire and medical record taken at the time of admission for a diagnosis. The overall agreement between two sources was evaluated. The factors affecting the disagreement between two sources and the level of data omission of the smoking habits in medical records were analyzed suing multiple logistic regression. RESULTS: The smoking habit between two sources showed moderate overall agreement(Kappa (kappa)=0.60). The lowest agreement was observed in the ex-smokers(kappa=0.49). Multivariate analysis revealed an age of 65 or older to be a statistically significant factor associated with the increasing disagreement risk compared with those 64 or younger (OR 3.02; 95% CI 1.58-5.80). The omission rate of smoking habits in the medical records was 18.2%. Adenocarcinoma was shown to be a statistically significant factor of associated with an increasing omission rate compared with squamous cell carcinoma (OR 3.00; 95% CI 1.19-7.59). CONCLUSION: The smoking habits obtained from medical record moderately reflect their true behavior. However, the smoking habit data from medical record should be used with caution when being used in a clinical study or cohort study of lung cancer.
