Spontaneous coronary artery dissection is a rarely identified entity whose exact incidence, etiology, pathogenesis, medium-term evolution and optimal treatment have not yet been firmly estabilished. The cause of spontaneous disection remains unclear but theories of etiology include a medial eosinophilic angiitis, pregnancy induced degeneration of collagen and rupture of the vasovasoum. Most paients die suddenly, but a clinical spectrum is seen including and unstable angina, myocardial infarction and cardiogenic shock. We experienced 4 cases with spontaneous coronary artery dissection found angiographically which caused myocardial infarction and unstable angina. Our patients were treated medically.

The congenital absence of an inferior vena cava is an uncommon abnormality. With the advent of modern imaging techniques, such cases are being found with increasing frequency. Here we report a case of a renal cell carcinoma with the absence of an inferior vena cava in a 44 year-old male. He was referred for a further evaluation of a right renal mass, which was observed by ultrasonography, and for persistent epigastric discomfort. Computed tomography showed a huge mass in the right kidney and multicystic lesions in the left. In addition, the inferior vena cava had disappeared at the infrahepatic portion. He was treated with a right radical nephrectomy.

PURPOSE: Transcatheter closure of patent foramen ovale (PFO), atrial septal defect (ASD) and patent ductus arteriosus (PDA) is a new and less traumatic technique than open heart surgery. One of the more popular occluding devices is the Amplatzer(R) septal occluder which is made of nitinol. The present study was undertaken to evaluate the safety and release of nickel after implantation of Amplatzer(R) occluder in patients with PFO, ASD and PDA. METHODS: Random blood samples were obtained from 25 patients with Amplatzer(R) PFO, ASD, PDA occluder during 4-year and 7-month post closure period. The nickel content in the specimens was determined using atomic absorption spectrometer. RESULTS: All patients showed satisfactory clinical improvements and there was no echocardiographic evidence of complications. During the post closure, concentrations of nickel in serum were within normal range with values 0.2 ug/dL. CONCLUSION: Nickel seems to be released from Amplatzer(R) occluder. The dissolusion of nickel from Amplatzer(R) occluder is minimal and systemic rise in serum levels of nickel are within normal range. However, further studies are needed to evaluate biological effects in patients with nickel hypersensitivity.

BACKGROUND AND OBJECTIVES: Vestibular evoked myogenic potential (VEMP) is a relatively new diagnostic tool that is in the process of being investigated in patients with specific vestibular disorders. In this study, we examed the responses of VEMP in patients who complained of dizzines. MATERIALS AND METHOD: Eighty-six patients with complaint of dizziness and ten normal volunteers are included in this study. Among these patients, forty-six patients were diagnosed as unilateral vestibulopathy (A), five patients were bilateral vestibulopathy (B), nine patients were sudden sensorineural hearing loss with vertigo (C), fifteen patients were benign paroxysmal positional vertigo (D) and eleven patients were Meniere's disease (E). We compared VEMP parameters in each group. RESULTS: In each group, abnormal response in VEMP was 33%(A), 0%(B), 11%(C), 12%(D) and 36%(E) respectively. and there was no absent VEMP formation, and there was no abscent VEMP formation. CONCLUSION: VEMP is a promising method for diagnosing and following patients with many vestibular disorders.

This study was undertaken to develop species-specific forward and universal reverse PCR primers for the detection of Streptococcus sobrinus. These primers target the variable regions of the 16S ribosomal RNA coding gene (rDNA) and their specificity was tested against 10 strains of S. sobrinus strains and 20 different species of oral bacteria using serial dilutions of the purified genomic DNA of S.sobrinus ATCC 33478T . Our data show that species-specific amplicons were obtained from all the S. sobrinus strains tested but not from other species. Both direct and nested PCR could detect as little as 400 pg and 4 fg of genomic DNA from S. sobrinus ATCC 33478T , respectively. This result suggests that these PCR primers are highly specific and sensitive and applicable to the detection of S. sobrinus.
