Garlic and mugwort have long been used in traditional medicine to prevent various diseases. Several in vitro studies have reported protective efficacies of garlic and mugwort in cases of gastric cancer. In the present study, we investigated the cancer preventive effects of garlic and mugwort mixture extract (GME) in a Helicobacter (H.) pylori-associated gastric carcinogenesis mouse model. To induce gastric cancer, C57BL/6 mice were treated with N-methyl-N-nitrosourea and H. pylori. Various concentrations of GME (0, 100, 500, and 1,000 ppm) were then fed to the mice for 38 weeks, after which the tumor tissues were examined for histopathology, mucin histochemistry and beta-catenin. The incidence of gastric tumors was significantly lower in the highest dose GME-treated mice (46.7%) than control mice (85.7%) (p < 0.05). The multiplicity and size of tumors were also significantly reduced by GME feeding in a dose-dependent manner (p < 0.01). Furthermore, GME suppressed the H. pylori-associated chronic inflammation measured by histologic grading of H. pylori density, chronic gastritis, glandular atrophy and intestinal metaplasia in non-tumorous gastric mucosae. Our data suggest that GME suppresses gastric tumorigenesis via suppression of H. pylori-associated chronic inflammation.

PURPOSE: In order to prepare long-term alternatives to surgical residency training and workforce policies in Korea, objective data are needed; in addition, determination of the status of surgical procedures being performed is also needed. METHODS: Cases of surgeries performed by board-certified Korean surgeons for 1 year, from July 2009 to June 2010 were reviewed and analyzed. Variation of the last five years was also investigated against the number of surgery cases of the same item and for data on status of population, medical institutions, and surgeons. RESULTS: Difficulty in distribution of a given surgery varied according to the classification of medical institution types, and performance of highly difficult surgeries occurred more in tertiary hospitals. The number of surgeries has increased over the last 5 years (28.1%). The number of surgeries among elderly patients (41.5%), high difficulty (41.8%), and tertiary hospitals (34.9%) has especially increased. There has been no increase in the number of diagnosis related group claim cases for the last 5 years (-0.8%). 43.3% of surgeons working at private clinics in Korea did not present surgery as an indicating item of their clinics. CONCLUSION: While the demand for surgeons in high risk and highly difficult surgeries is continuously increasing, stagnation is expected in the traditional area. Considering the proportion and current status of surgeons working at private clinics, the need for a realistic reduction in the quota of surgical residents and reconsideration of personnel policies is raised.

PURPOSE: This study aimed to analyze the efficacy and toxicity of gemcitabine plus platinum chemotherapy for patients aged 70 years or older with advanced non-small-cell lung cancer (NSCLC). MATERIALS AND METHODS: We reviewed the records of stage IIIB, IV NSCLC patients or surgically inoperable stage II, IIIA NSCLC patients who were aged 70 years or older when treated with gemcitabine (1,250 mg/m2) plus cisplatin (75 mg/m2) or carboplatin (AUC5) chemotherapy from 2001 to 2010 at Seoul St. Mary's Hospital, Uijeongbu St. Mary's Hospital and St. Vincent's Hospital. Gemcitabine was administered on days 1 and 8, and cisplatin or carboplatin was administered on day 1. Treatments were repeated every 3 weeks for a maximum of 4 cycles. RESULTS: The median age of the 62 patients was 73.5 years (range, 70 to 84 years). Forty-one (66%) patients exhibited comorbidity. The mean number of treatment cycles was 3.9. The compared average relative dose intensity of gemcitabine plus platinum chemotherapy was 84.8%. The median progression-free survival and overall survival (OS) were 5.0 months and 9.4 months, respectively. Reduced Eastern Cooperative Oncology Group (ECOG) performance status (none vs. > or =1) and weight loss (<5% vs. > or =5%) after treatment were found to have a significant effect on OS (p=0.01). CONCLUSION: Gemcitabine plus platinum chemotherapy is an effective treatment option with an acceptable level of toxicity in patients aged 70 years or older with good performance status in advanced NSCLC.

Tuberculosis is one of the main infectious health problems in Korea, and a combination of antibiotics is required to treat this illness. The combination therapy with rifampicin, isoniazid, ethambutol and pyrazinamide has many adverse reactions and there have been several case reports about pseudomembranous colitis (PMC) after anti- tuberculosis treatment. Rifampicin is regarded as a main cause of anti-tuberculosis induced PMC because of its bacteriocidal effect, and interruption of the offending drug, such as rifampicin, is usually necessary to treat the PMC. However, in patents with uncompensated tuberculosis, the discontinuance of anti-tuberculosis medication accentuates the disease severity, and continuance of the anti-tuberculosis medication is necessary to overcome the tuberculosis. We report here on a case in which the anti- tuberculosis agents induced PMC in 32 year old female who was diagnosed with active pulmonary tuberculosis. She was treated with maintenance of the anti-tuberculosis medication and also the addition of both oral metronidazole and probiotics.

Although Morgagni hernias are rarely symptomatic, an 88-year-old woman presented with severe abdominal pain and distension due to large bowel obstruction. The transverse colon and omentum were herniated through an anterior medial diaphragmatic defect in the right thorax. The plain abdominal X-rays indicated intestinal obstruction and the plain chest X-ray showed hazy mass-like densities. The multi-detector row computed tomography (MDCT) findings were compatible with a Morgagni hernia. This diagnosis of a Morgagni hernia was confirmed at immediate surgery.

Foreign bodies of the upper gastrointestinal tract are found in all age groups, and the foreign bodies can be ingested incidentally or intentionally. They are usually common in children, but they have also been discovered in adults with esophageal disease, artificial teeth, mental retardation, in patients seeking secondary gains and in alcoholics. The types of foreign bodies vary for different social and cultural conditions, and can include coins, corks, toys, fish bones, toothbrushes, needles, nails and pens. Foreign bodies of the upper gastrointestinal tract are usually passed into the intestinal tract spontaneously, but sometimes intervention is required. We report a case of an 80-year-old man with a past medical history of depressive disorder that had ingested adhesives. The adhesives present in the esophagus were removed by the use of therapeutic endoscopy. However, the adhesives in the stomach were too large to remove by the use of an endoscopic procedure, and gastrotomy was performed.

When tracheal invasion of a malignant tumor or tracheal stenosis of a benign origin exists at the lower or anterior part of the trachea, tracheal intubation or conventional tracheostomy may be difficult, and in these cases a modified tracheostomy through the lower or lateral part of the trachea would be necessary. We present 6 cases of modified tracheostomy performed with satisfactory results in severe tracheal stenosis that developed in the lower or anterior part of the trachea.

Renal tubular dysfunctions have been observed in hydronephrosis, resulting in metabolic acidosis, hyperkalemia and excessive free water diuresis. These findings are occasionally found in infant and children. Batle et al. first reported distal tubular acidosis associated with low potassium excretion resulting from aldosterone resistance in adults with obstructive uropathy. We have experienced a case of transient hyperkalemia and hyperaldosteronism secondary to hydronephrosis in 63-year-old female patient. The causes of hyperkalemia were examined under the impression of secondary adrenal insufficiency due to corticosteroid abuse or hyporeninemic hypoaldosteronism due to diabetic nephropathy. But it proved to be resulted from hyperaldosteronism due to hydronephrosis. The hyperkalemia resulting from hyperaldosteronism is rare in adults. It may result from aldosterone resistance at distal nephron due to obstructive uropathy or the defect of distal nephron in hydrogen and potassium secretion in the distal nephron rather than from aldosterone deficiency. After she underwent percutaneous nephrostomy, serum potassium was maintained within normal range. She performed total cystectomy with ureterocutaneostomy in purpose for treatment of bladder cancer. So we report this case with a review of literature.

BACKGROUND: As the frequency of colonoscopic approaches increases, we need a less painful premedication for colonoscopy. We used midazolam as a premedication agent. It has more rapid onset of action than that of diazepam and its duration is shorter. The purpose of this study was to examine the clinical application of midazolam. METHODS: Fifty patients underwent colonoscopies. An average dose of midazolam, 0.07 mg/kg, was given to patients intravenously as premedication. We measured systolic and diastolic blood pressures, pulse rates, respiratory rates, and oxygen saturation (SaO2) using pulse oxymetry before and after the injection. A Trieger test was accomplished before and after the procedures. We examined the levels of consciousness with verbal and physical stimulation during the colonoscopy. The examiners noted the degree of amnesia and pain after colono-scopy. We examined the patients' satisfaction and endoscopists' assessments. RESULTS: 1) Systolic, diastolic blood pressures and respiratory rates showed no significant changes. But, pulse rates increased meaningfully at 15 minutes after the injection of midazolam (p <0.05). 2) The Trieger test showed meaningfully increased numbers of missed dots after the injection of midazolam. 3) The levels of consciousness during the test showed alertness in 22 patients (44%), drowsy mentality in 22 patients (44%) and stuporous mentality in 6 patient (12%). 4) The degree of amnesia after examination showed recall in 26 patients (52%), partial recall in 10 patients (20%) and total amnesia in 14 patients (28%). 5) Forty-five patients (90%) acknowledged this procedures to be more comfortable than previous procedures. CONCLUSIONS: Midazolam stabilized vital signs and oxygen saturation, therefore midazolam can be used safely as premedication for colonoscopy. Thirty-six patients (72%) recalled the procedures totally or partially. But, the relief of pain compared favorably to the degree of amnesia. We concluded that mida-zolam (0.07 mg/kg) was the safe and effective premedication for colonoscopy.
