We treated 4 patients with uric acid calculi in the renal pelvis or ureter with alkaline fluid irrigation through percutaneous nephrostomy (PCN) tube. Initial presentations were anuria or severe flank discomfort, we performed PCN to relieve such obstructive symptoms caused by uric acid calculi. We tried to dissolve uric acid calculi with normal saline mixed to sodium bicarbonate through a PCN tube. The success of therapy is believed to be related to the direct and constant urinary alkalinization effect obtained with irrigation compared to be the intermittent alkalization that occurs when oral agent are used.

BACKGROUND: Because of increasing incidence of astherosclerosis, the incidence of contrast nephrotoxicity is increasing in Korea. This study was designed to investigate the clinical characteristics and risk factors of contrast dye nephrotoxcity in patients performing arteriography. METHODS: This study included 511 adult patients who performed arteriography. We retrospectively evaluated the incidence, clinical course, and risk factors of contrast dye-induced acute renal failure via medical records. Acute renal failure was defined as a rise of serum creatinine more than 50% of baseline levels 2-3 days after exposure of contrast dye. RESULTS: Of the total 511 patients, 23 patients (4.5%) had acute renal failure. The mean age of these patients was 57+/-0 years and the number of male was 14. The mean duration between the exposure and development of acute renal failure was 2.0+/-.7 days. The serum creatinine level maximally increased to 3.2+/-.9 mg/dL at 6.3+/-.1 days after the exposure. Oliguria and pulmonary edema developed in 8 and 7 patients, respectively. Four patients needed hemodialysis treatment. Of the total 23 patients with acute renal failure, 19 patients recovered with conservative treatment and 3 patients died without recovery of renal function and 1 patients progressed end stage renal failure. Renal insufficiency and dosage of contrast dye were independent risk factors of development of acute renal failure. CONCIUSION: Contrast dye-induced acute renal failure occurred in 4.5% of patients performing arteriography. Most cases of acute renal failures completely recovered but 4 case needed hemodialysis and 1 case progressed to end stage renal failure. Renal insufficiency and dosage of contrast dye were independent risk factors of development of acute renal failure.

Double pylorus is either a congenital abnormality or an acquired complication of peptic ulcer disease. An accessory channel normally connects the lesser or greater curvatore of the prepyloric antrum with the duodenal bulb. Three cases of double pylorus, an unusual complication of peptic ulcer disease is herein reported. A peptic ulcer lay in the accessory channel in all cases. In one of the cases, the fistula closed spontaneously after Helicobacter pylori eradication. The remaining 2 patients became asympto-matic despite the persistence of the accessory channel.

PURPOSE: When cells are subjected to stressful stimuli such as, heat shock, toxic metal, nutrient deprivation, and metabolic disruption, they increase production of specific stress proteins that buffer them from harm. We reported that the expression of a navel 90 kDa cellular protein was increased by the infection of a fish rhabdovirus and heat shock in a fish cell. This new 90 kDa protein is not expressed in normal animal tissues but is highly induced in progressively transforming tissues or cells. That gives us some ideas tl at it is possible for this stress protein to be expressed in specific human cancer tissues. MATERIALS AND METHODS: Commercialized checkerboard multi-tumor block (DAKO Co. Carpinteria, CA) was used for immunohistochemical analysis. The samples of human gastric cancer, colon cancer and breast cancer tissues were evaluated by Western blot and Northern blot for overexpression of the novel 90 kDa stress protein. Sera of those patients were analyzed by ELISA for the presence of antibody against the novel 90 kDa stress protein. RESULTS: Immunohistochemical staining of human tumor tissue blocks showed significant immunostaining of novel 90 kDa stress protein in carcinomas such as colon cancer, breast cancer and stomach cancer but no apparent immunostaining in sarcomas. Coinciding with the immunohistochemical result, Western blotting and Northern blotting analyses indicate that the expression of the novel 90 kDa stress protein was increased in carcinomas. In addition, the antibody titer against the novel 90 kDa stress protein was found to be elevated in the sera of cancer patients. CONCLUSIONS: The novel 90 kDa stress protein gene expression was elevated in carcinomas such as gastric cancer, breast cancer and colon cancer. These findings suggest that this new stress protein can be used as a tumor marker and may function as a chaperone in tumor growth.

The Committee of Clinical Practice Guidelines of the Korean Diabetes Association (KDA) updated the previous clinical practice guidelines for Korean adults with diabetes and prediabetes and published the seventh edition in May 2021. We performed a comprehensive systematic review of recent clinical trials and evidence that could be applicable in real-world practice and suitable for the Korean population. The guideline is provided for all healthcare providers including physicians, diabetes experts, and certified diabetes educators across the country who manage patients with diabetes or the individuals at the risk of developing diabetes mellitus. The recommendations for screening diabetes and glucose-lowering agents have been revised and updated. New sections for continuous glucose monitoring, insulin pump use, and non-alcoholic fatty liver disease in patients with diabetes mellitus have been added. The KDA recommends active vaccination for coronavirus disease 2019 in patients with diabetes during the pandemic. An abridgement that contains practical information for patient education and systematic management in the clinic was published separately.
