Calciphylaxsis is a rare and life-threatening condition of progressive cutaneous necrosis secondary to calcification of small and medium-sized blood vessels. It is seen almost exclusively in patients with end-stage renal disease, in a setting of secondary hyperparathyroidism and hypercalcemia resulting in metastatic vascular calcification, We experienced a case of calciphylaxsis manifested with chara- cteristic cutaneous lesions that began as tender violaceous livedoid discolorations and subsequent ulceration on the proximal aspect of the extremities and on the lower part of the abdomen. Histologically, calcification is found in small and medium-sized blood vessels in the deep dermis and subcutaneous tissue. The patient had been treated for hypercalcemia, not complicating renal failure, but the cause of hypercalcemia was not found. However, the hypercalcemia was contolled and the skin lesions also improved after oral prednisolone therapy. Our case is a rare presentation of calciphylaxsis in the absence of renal failure, reversibly improved.

Intracellular organelle transport is essential for morphogenesis and functioning of the cell. Kinesins and kinesin-related proteins make up a large superfamily of molecular motors that transport cargoes such as vesicles, organelles (e.g. mitochondria, peroxisomes, lysosomes), protein complexes (e.g. elements of the cytoskeleton, virus particles), and mRNAs in a microtubule- and ATP-dependent manner in neuronal and non-neuronal cells. Until now, more than 45 kinesin superfamily proteins (KIFs) have been identified in the mouse and human genomes. Elucidating the transport pathways mediated by kinesins, the identities of the cargoes moved, and the nature of the proteins that link kinesin motors to cargoes are areas of intense investigation. This review focuses on the structure, the binding partners of kinesins and kinesin-based human diseases.

Tuberculosis of the thyroid gland is extremely rare with few cases reported in recent years. Tuberculosis may involve the thyroid gland in two main forms. The more common of theses is miliary spread to the thyroid as part of generalized dissemination and less commonly focal or caseous tuberculosis of the thyroid may occur, presenting as a nodule, as a thyroiditis, as a abscess, or as carcinoma like.We experienced two cases of tuberculosis of the thyroid gland presenting with palpable thyroid nodule in 26 year-old female and 65 year-old female patients. They have been clinically and biochemically euthyroid and their thyroid scans demonstrated a cold nodule at right thyroid gland. We found no evidence of tuberculosis elsewhere. The goiter was removed surgically and confirmed to be tuberculosis. They were medicated antituberculous agents after operation and followed up regulary out patient department.We report the cases of two patients with tuberculosis involving thyroid with reviews of literature.

OBJECTIVE: To test if the intake of H2 receptor antagonists (H2-RAs) increases the risk of gastric cancer in the elderly. METHODS: The source population for this study was drawn from the responders to a questionnaire survey administered to the Korea Elderly Pharmacoepidemiological Cohort (KEPEC), who were beneficiaries of the Korean Medical Insurance Corporation, were at least 65 years old, and residing in Busan in 1993. The information on H2-RAs exposure was obtained from a drug prescription database compiled between Jan. 1993 and Dec. 1994. The cases consisted of 76 gastric cancer patients, as confirmed from the KMIC claims data, the National Cancer Registry and the Busan Cancer Registry. The follow-up period was from Jan. 1993 to Dec. 1998. Cancer free controls were randomly selected by 1:4 individual matching, which took in to consideration the year of birth and gender. Information on confounders was collected by a mail questionnaire survey. The odds ratios, and their 95% confidence intervals, were calculated using a conditional logistic regression model. RESULTS: After adjusting for a history of gastric ulcer symptoms, medication history, and body mass index, the adjusted OR (aOR) was 4.6 (95% CI=1.72-12.49). The odds ratio of long term use (more than 7 days) was 2.3 (95% CI=1.07-4.82). The odds ratio of short term use was 4.6 (95% CI=1.26-16.50). The odds ratio of parenteral use was 4.4 (95% CI=1.16-17.05) and combination use between the oral and parenteral routes (aOR, 16.8; 95% CI=1.21-233.24) had the high risk of gastric cancer. The aOR of cimetidine was 1.7 (95% CI=1.04-2.95). The aOR of ranitidine was 2.0 (95% CI=1.21-3.40). The aOR of famotidine was 1.7 (95% CI=0.98-2.80). CONCLUSION: The intake of H2-RAs might increase the risk of gastric cancer through achlorhydria in the elderly.

OBJECTIVES: Recently, recombinant FSH (rFSH) has been manufactured using a Chinese hamster ovary cell line transfected with the gene encoding human FSH. Both rFSH and urinary gonadotropin (uFSH) could be used for controlled ovarian hyperstimulation (COH). However, uFSH implies a number of disadvantages, such as batch-to-batch inconsistency, no absolute source control, dependence on large amounts of urine, low specific activity, and low purity. The purpose of this study was to evaluate the efficacy of rFSH in human IVF-ET program. MATERIALS AND METHODS: A total of 508 infertile women was enrolled in this study. They are classified into rFSH group (n=177) or uFSH group (n=331), and all of them were matched by age and cause of infertility in same period. The Puregon(R) (Organon, Holland) was used as rFSH, and the Metrodin-HP(R) (Serono, Switzeland) and Humegon(R) (Organon, Holland) was used as uFSH. We subdivided the patients into three age groups. The outcomes of IVF-ET program were analyzed using the statistical package for social sciences (SPSS). RESULTS: There was no significant differences in the level of estradiol on hCG injection day, the numbers of retrieved oocytes, matured oocytes, fertilized oocytes, transferred embryos, frozen embryos between the two groups. The total dose (IU) of gonadotropin for COH was significantly lower in the rFSH group compared to uFSH group (1339+/-5491.1 vs 2527.8+/-1075.2 IU, p<0.001). Clinical pregnancy rate per embryo transfer in the rFSH group showed increasing tendency, compared to the uFSH group, but there was no statistical significance (35.2% vs 29.3%). Our results demonstrated that the relative efficiency of rFSH compared with uFSH is higher in older patients. CONCLUSIONS: The ovarian stimulatory effect and clinical outcome of recombinant FSH was similar to that of the urinary gonadotropin. The IVF-ET cycles with significantly lower dose of gonadotropin in rFSH group showed comparable results. Therefore, we suggest that recombinant FSH is more potent and effective than urinary gonadotropin.

BACKGROUND: induction of analgesia is frequently required during undergoing reduction of fractures or dislocation in the emergency department. METHODto induce analgesia should be easy, convenient, and safe because patients are not always in fasting state. Nitrous oxide inhalation has been known as a good method of analgesia in emergency patients. PURPOSE: This study was aimed to evaluate the efficacy and safety of nitrous oxide analgesia in the emergency department. METHOD: We prospectively studied 34 patients undergone reductions of fractures in the emergency department. Nitrous-oxide was the sole source of analgesia. The Visual Analogue Scale(VAS) was rated by the emergency physician before nitrous oxide inhalation,5 minutes after inhalation and reduction procedures. RESULTS: No complication such as vomiting, respiratory depression, or a change in oxygen saturation resulted from the use of nitrous-oxide. Ninety one percent of patients obtained an analgesic effect. However, 9% of patients did not experience any analgesic effect after inhalation of nitrous oxide. In subgroup analysis for analgesic effect of nitrous-oxide, nitrous oxide provided only partial analgesia for acute pain in open fracture group. VAS was significantly lower after inhalation than before inhalation of nitrous oxide in simple fracture group. However, VAS of simple fracture group was increased during closed reductions, which indicated incomplete relief of pain by nitrous oxide. Nitrous oxide inhalation foiled to relieve pain during reduction in patients with open fracture or dislocation. CONCLUSION: Administration of nitrous-oxide, when used as the sole source of analgesia, is not the ideal method of analgesia during reduction of fractures or dislocations.

Transcutaneous cardiac pacing(TCP) is a rapid, safe, noninvasive and easily utilized form of emergency cardiac pacing, with hemodynamically similar to transvenous cardiac pacing. This paper reports the result of transcutaneous pacing in a series of patients in emergency department.32 patients with bradyanhythmia were enrolled during the study period. TCP was successful in 29(91%) patients. No evidence of electrical capture was seen in two patients in asystole and a patient with ventricular escape rhythm. Mean capture threshold was 66 mA. Transvenous pacemaker was inserted in 18(56%) of the 32 patients during transcutaneous cardiac pacing. Twenty(61%) of the 32 patients survived and eventually discharged. Ten patients(31%) were died of uncorrectable underlying disease in spite of successful ECG capture and palpable pulse by TCP. In conclusion, TCP is a reliable, noninvasive method that offers the possibility to initiate pacing within seconds and can be used by any emergency medical staff. In our opinion, it should be considered as the first choice of emergency treatment of hemodynamically unstable bradyarrhythmia.

Black-pigmented bacteria have been implicated in the endodontic infections. This group of microorganisms includes Porphyromonas endodontalis, Porphyromonas gingivalis, Prevotella intermedia, and Prevotella nigrescens. The organisms display a wide variety of virulence factors that may be pertinent to acute endodontic infections. The aim of this study was to identify P. endodontalis, P. gingivalis, P. intermedia, and P. nigrescens by using special potency disk test, filter paper spot test, 16S rRNA gene-directed PCR, and API 32A. Microbial samples were collected from root canals of 33 intact teeth with necrotic pulp and/or apical periodontitis. Conventional laboratory methods were used for identification of the strains of black pigmented bacteria. Eighteen of 33 samples were positive for the growth of black-pigmented bacrteria. Five colonies were cultured from each pure cultured colonies from Brucella agar plate. Seventy seven colonies were positive for the growth of black-pigmented bacteria. Thirty three of 77(42.6%) were identifed as P. nigrescens, 10 of 77(12.9%) were P. gingivalis, 6 of 77(7.8%) were P. endodontalis, 10 of 77(12.9%) were P. intermedia. On the contrary the reference strains of P. nigrescens, experimental strains of P. nigrescens was sensitive to kanamycin in special potency disk test. 16S rRNA gene PCR and API test after rapid presumptative identification methods, such as special potency disk test and filter paper spot test, would be accurate detection methods for black-pigemented bacteria.

BACKGROUNDS/AIMS: Complete elimination of intrahepatic duct (IHD) stones is difficult and IHD stone disease is frequently associated with various complications, recurrence and sometimes cholangiocarcinoma. Therefore, we analyzed the long-term surgical results and evaluated the management currently considered appropriate. METHODS: Overall 110 patients who had been diagnosed with benign IHD stone disease and who underwent surgical treatment were enrolled in this study. The patients were categorized into three groups according to the type of surgery performed; liver resection (LR) group, intrahepatic duct exploration (IHDE) group and hepaticoenterostomy (HE) group. We compared and analyzed the results of these three groups. RESULTS: The number of cases in the LR group, IHDE group and HE group were 77, 25 and 8 respectively. The LR group required a longer operation time (p=0.000), more frequent transfusion (p=0.028) and had higher morbidity (p=0.049). However, the LR group had a higher clearance rate (90.9%) (p=0.000) than the other groups. In addition, there were a total of 22 cases of IHD stone recurrence during the follow-up, but there was no statistically significant difference among the three groups. The location of IHD stones was related to a risk factor for incomplete stone removal, but not for recurrence. CONCLUSION: The fundamental principle for the treatment of IHD stone disease should be liver resection. However, it can lead to a longer operative time and higher rate of complications than the other procedures. There is also no difference in the IHD stone recurrence rate among the procedures. Therefore, these alternative and minor procedures could also be taken into account for patients with poor preoperative condition.
