Infective endocarditis related to pacemaker implantation is a rare complication. However, it is a potentially lethal complication with a mortality rate of 30 to 35%. Infective endocarditis associated with pacemaker implantation usually involves the right heart and tricuspid valve. Conservative treatment without complete removal of the entire pacing system is prone to fail (i.e. result in infection relapse or development of sepsis). Therefore, the total extraction of the entire pacemaker system should be considered as standard therapy for most patients with pacemaker-related endocarditis and for many patients with local infectious symptoms at the site of pacemaker implantation to achieve complete recovery. We report a case of a 42-year-old man with documented pacemaker related left-sided endocarditis that was associated with multiple embolic events. Also, we review the literature regarding pacemaker-related endocarditis and local wound infection, in particular with respect to the modalities of treatment.

Tibolone (Livial, NV Organon, Oss, Netherlands) is a synthetic steroid which exhibits estrogenic, progestogenic and androgenic activity. In the endometrium, tibolone dose not have estrogenic activity, but dose have intrinsic progestogenic activity. Therefore, it dose not stimulate the endometrial tissue which usually undergoes atrophy. Tibolone has been associated with a relatively low incidence of vaginal bleeding and endometrial hyperplasia. Recently. a few reports have been published even less frequently describing invasive endometrial cancer during tibolone therapy. We report a case of histologically diagnosed adenocarcinoma of the endometrium in women using tibolone. Although we do not suggest causability between the use of tibolone and the development of endometrial malignancy, but we should alert physicians to thorough investigation in patients presenting with vaginal bleeding and the increase of endometrial thickness by sonogram while on tibolone.

An abdominal pregnancy is defined as an ectopic pregnancy, which implants in the peritoneal cavity and can be classified as either primary or secondary. The incidence of abdominal pregnancy is increased after IVF or GIFT, induced abortion, endometriosis, and intrauterine devices may also contribute to an increased incidence. Early diagnosis and appropriate surgical management, regardless of stage of gestation, appear to be important in achieving good results. A case of early primary abdominal pregnancy which was implanted on the left uterosacral ligament. We report the case and brief review of literature.

BACKGROUND: The Korean Red Cross (KRC) has stored blood donor samples for 10 years under -20degrees C since 2004. These samples have been used for investigating transfusion related infections and for Look-back studies. We designed an experimental scheme to verify the stability of stored blood samples. METHODS: We collected and prepared samples such as blood donor samples (HBV, HCV, HIV nucleic acid positive; n=90), the HIV infected patient samples (n=20), the WHO nucleic acid international standards serologic positive samples (HBsAg, anti-HCV, anti-HIV; n=120) and the negative samples (n=20). The samples were aliquoted in cryo tubes with volumes of 0.5~5 mL and they were stored at -20~-30degrees C and -70~-80degrees C. We used enzyme immunoassay, chemiluminescence immunoassay and quantitative PCR for the base line and the follow up studies. The linear mixed statistical model using SAS 9.1 for windows was used for statistical analysis. RESULTS: The results of the baseline test of the stored samples showed a variable range of viral load (10(1)~10(7) IU/mL or copies/mL) and optical density (S/CO 3.0~500). The results of the stored samples after 6 month (n=82) did not show any significant differences compared to the baseline data for the viral loads (P>0.05) and the qualitative serologic tests. CONCLUSION: We established an experimental scheme to verify the stability of the stored blood donor samples. From now on, the stability of the stored samples is going to be monitored by every 6 month for 10 years.

This study describes the purification and characterization of type II restriction endonuclease of Helicobacter pylori in order to understand the DNA restriction and modification of H. pylori. H. pylori cell extract was subjected to polyethyleneimine treatment, salt precipitation, heparine-sepharose column chromatography, and fast protein liquid chromatography (FPLC) using Resource Q column and Mono Q column to purify the type II restriction endonuclease. Hpy51-I was characterized to recognize the sequneces 5`-GT(G/C)AC-3`, yielding 5-base 5` protruding ends. The restriction sequence was identical to that of Tsp 45 I. The enzyme exhibited its maximal activity in the presence of 10-20 mM LaCl, but was inhibited completely in the presence of more than 80 mM NaCl. The enzyme showed its maximal activity in the presence of 1-10 mM MgC1(2). The optimal pH and temperature for enzyme activity was pH 9.0 and 37 degrees C, respectively. MnC1(2) could not substitute for MgC1(2) in reaction mixture. And addition of j3-mercaptoethanol and bovine serum albumin in reaction mixture led to loss of enzyme activity of Hpy51-I. The whole cell extract of H. pylori strain 51 was confirmed to carry the enzyme activity for methylation of Hpy51-I-recognised sequence. Hpy51-I digested genomic DNAs of enteric bacteria to less than I kb while it could not cut the genomic DNAs of H. pylori isolates. In this study, the type II restriction enzyme (Hpy51-I) of H. pylori was identified and characterized its biochemical properties, demonstrating that Hpy51-I might be one of the barriers for preventing the introduction of foreign DNAs into H. pylori.
