BACKGROUND: Chlamydia trachomatis is one of the most common causative agents of the sexual transmitted diseases, and the accurate diagnosis and early treatment are very important to prevent the transmission. So, we evaluated the polymerase chain reaction (PCR) and QuickVue(TM) (Quidel Corp. San Diego, CA) EIA method as a routine clinical laboratory test. METHODS: The 80 cervical swab samples including pelvic inflammatory disease, cervicitis and tube-ovarian abscess were tested using PCR with plasmid specific primers T1, T2 and commercially available QuickVue(TM) EIA kit. RESULTS: The positivities of the PCR and QuickVue(TM) EIA test were 17.5% (14/80 samples) and 12.5% (10/80 samples), respectively. There were 95% (76/80 samples) of positive or negative result concordance rates and 5% (4/80 samples) of disconcordance between the two methods, in which showed PCR positive and EIA negative results. CONCLUSIONS: We assume that PCR and QuickVue(TM) method are highly confident as a routine clinical laboratory diagnostic test for C. trachomatis infection. But more careful interpretation of QuickVue(TM) EIA and the additional study for variable samples will be needed.

Spontaneous intracranial epidural hematoma (EDH) due to dural metastasis of hepatocellular carcinoma is very rare. A 53-year-old male patient with hepatocellular carcinoma, who was admitted to the department of oncology, was referred to department of neurosurgery because of sudden mental deterioration to semicoma with papillary anisocoria and decerebrate rigidity after transarterial chemoembolization for hepatoma. Brain computed tomography (CT) revealed large amount of acute EDH with severe midline shifting. An emergent craniotomy and evacuation of EDH was performed. Active bleeding from middle cranial fossa floor was identified. There showed osteolytic change on the middle fossa floor with friable mass-like lesion spreading on the overlying dura suggesting metastasis. Pathological examination revealed anaplastic cells with sinusoidal arrangement which probably led to spontaneous hemorrhage and formation of EDH. As a rare cause of spontaneous EDH, dural metastasis from malignancy should be considered.

OBJECTIVE: The aim of this study is to assess the relationships between maternal plasma and umbilical cord leptin concentrations and their effects on newborn birth weights, maternal body mass indices and fetal sex in term normotensive (NT) and preeclampsia (PE) women. METHODS: Blood samples were obtained at delivery from 20 NT group and another 20 from PE group of at least 36 weeks of gestation. And the umbilical cord samples were also taken from their newborns at birth. Plasma leptin levels were determined in both groups using a human recombinant leptin 125-I radioimmunoassay. RESULTS: Mean maternal plasma and umbilical cord leptin concentrations were 16.16+/-2.05 ng/ml and 7.11+/-1.01 ng/ml in NT group, 17.09+/-1.67 ng/ml and 8.55+/-6.63 ng/ml in PE group, and there was no statistical significances among them. The differences of leptin concentrations in maternal plasma and umbilical cord according to baby sex were not significant in both NT and PE groups. Plasma leptin concentrations were related with maternal weight gain and BMI in NT group and with body weight in PE group. The BMI and birth weights of the neonates have significant effects on the umbilical cord leptin concentrations in both NT and PE groups. CONCLUSION: In this study, no correlation was found between maternal plasma and umbilical cord leptin concentrations in both NT and PE groups. But maternal plasma leptin concentrations had positive correlations with maternal body weight, BMI, and body weight changes during pregnancy in both NT and PE groups. There were also positive correlations among umbilical cord leptin concentrations, BMI and birth weights of the neonates of NT and PE groups term. Therefore umbilical cord leptin is considered to be the index of fetal birth weight.

OBJECTIVE: The purpose of this study was to determine the clinical significance of intraventricular hemorrhage (IVH) in patients with ruptured aneurysms. METHODS: Of 1034 patients who were admitted to our hospital with ruptured aneurysms between 1994 and 2007, 128 (12.4%) had IVHs. The clinical, radiologic characteristics, and surgical outcomes in the IVH group were compared with the no-IVH group. RESULTS: The IVH group had a shorter time interval to admission. The incidence of IVH was significantly higher in patients > 70 years of age (p=0.021), males (p=0.000), alcohol abusers (p=0.039), patients with a Glagow Coma Scale (GCS) < or =8 (p=0.000), and patients with a Hunt and Hess grade of 4-5 (p=0.000). IVH was more common in patients with ruptured posterior circulation aneurysms (p=0.000) and anterior communicating artery aneurysms (p=0.036). The incidence of thick, diffuse subarachnoid hemorrhage (SAH; p=0.004), intracerebral hemorrhage (ICH) >10 cc (p=0.006), rebleeding (p=0.010), and shunt-dependant hydrocephalus (p=0.000) was significantly higher in the IVH group than the no-IVH group. The mortality rate in the IVH group was significantly higher than the no-IVH group (48.4% versus 22.1%). The amount of IVH had an influence on the mortality; IVH involving all of the ventricles (59.7%) and IVH only involving some of the ventricles (33.9%) was associated with a 6.6- and 2.3-fold higher mortality than the no-IVH group, respectively. IVH was significantly associated with a poor surgical outcome; however, this association was not significant in patients with a GCS < or =8, or histories of rebleeding or seizures. CONCLUSIONS: In patients with ruptured aneurysms, IVH reflects the clinical severity of SAH. IVH has a negative influence on surgical outcome, except in patients with a poor clinical status pre-operatively.

Morel-Lavallée lesions (MLL) create pre-fascial space by shearing the subcutaneous tissues away from the underlying fascia, in a patient with trauma. Necrosis of the overlying skin can develop over a wide area of the lesion. The lesion might be contaminated by the surgical site due to careless intrusion when treating the combined arteriopathy. A 70-year-old woman presented with avulsion of the skin over the right foot and bilateral leg pain following a car accident. Computed tomography showed bilateral popliteal artery occlusion with large hematoma on both legs. Percutaneous angioplasty was performed with successful restoration of the flow. However, the skin color changes over time. Necrosis of the skin occurred over a wide area of the right leg. Extensive debridement was performed, and the defect was covered with a skin graft. MLLs can occur in patients with multiple traumas, multiple vascular injuries, and complex skeletal injury. Vascular surgeons treating multiple traumas should be aware of the diagnostic and management options for MLL. It should be diagnosed early because it can be difficult to manage once the overlying skin develops necrosis.

PURPOSE: This study was performed to evaluate the effect of powered toothbrush with a wireless remote display on the subjective and objective oral hygiene improvement. METHODS: One hundred and fifteen subjects in healthy or mild gingivitis status between the ages of 20 and 90 were recruited and reviewed for study inclusion criteria. At first visit, 115 pre-screened subjects filled in the questionnaire form which consisted of demographic factors, behavioral factors (smoking, alcohol consumption), toothbrushing habits (brushing time and frequency), self-reported oral health status, and self-satisfaction. Baseline clinical indices (Plaque index, Gingival index) were also recorded by a periodontist. Subjects were instructed how to use powered toothbrush with a wireless remote display, and were provided with it. Thirty days after first visit, 90 subjects returned for the second assessment by self-reported questionnaire form and professional clinical checkup. Statistical analysis was performed using paired t-test for the difference between baseline and second visit data. The relationship among variables was examined with chi-square test and Fisher's exact test. RESULTS: Significant differences were not found on self-reported satisfaction related with sex, smoking, alcohol consumption (P<0.05). Self-reported tooth brushing habit was improved in the aspect of brushing time and frequency. Significant differences were found on the self-reported oral health status, self-satisfaction, and clinical indices between the baseline and second visit data (P<0.01). Clinical indices were significantly reduced after using powered toothbrush with a wireless remote display (P<0.01). No adverse reactions were reported during the study period. CONCLUSIONS: Powered toothbrush with a wireless remote display successfully promoted oral hygiene from the subjective and objective viewpoint after 30 days of home usage.

Vascular injuries after spine surgery may result in acute life-threatening hemorrhage, chronic arteriovenous fistula, or pseudoaneurysm formation. The interval between injury and rupture may range from seconds to years, and accordingly, a high index of suspicion is needed to make the diagnosis. Although acute and delayed vascular injury caused by placement of posterior pedicle screw fixation has been reported, the potential for large vessel disruption during posterior pedicle screw removal has been rarely reported. This case report concerns a 50-year-old man who developed an descending thoracic aortic pseudoaneurysm after posterior pedicle screw removal, diagnosed by chest computed tomography(CT) scan and transesophageal echocardiography(TEE).

BACKGROUND: The main cause of atherosclerotic peripheral vascular disease is known to be atherosclerotic processing. In patients with atherosclerotic peripheral vascular disease, other atherosclerotic diseases are frequently combined, especially coronary artery disease. There were some suggestions that the risk factors of the atherosclerotic peripheral vascular disease be different from the those of the coronary artery disease. The aim of this study was to evaluate the independent risk factors for the atheroslerotic peripheral vascular disease(PVD) without influence of coronary artery disease(CAD). METHODS: The study population was male patients with atherosclerotic peripheral vascular disease(n=66) documented by peripheral angiogram form February 1991 to Octobor 1993, and during their abmission all patients with suspected atherosclerotic peripheral vascular diaease underwent both peripheral angiogram and coronary angiogram. Careful history taking and physical examination and lipid battery sampling after at least 14 hours of fasting were also performed. RESULTS: 60% of patients with peripheral vascular disease also had coronary artery disease. There was no significant difference in total cholesterol, HDL cholesterol, LDL cholestrerol, triglyceride between patients with peripheral vascular disease and age-matched control. The prevalence of hypertension was higher in patients with peripheral vascular disease but with no statistical significance. Smoking(p<0.0001) and diabetes(p<0.05) were strongly associated with peripheral vascular disease. When patients without coronary artery disease were compared to control from the viewpoint of risk factors again, the results were the same, that is, smoking and diabetes were also associated with periperal vascular diseaes. CONCLUSION: The prevalence of associated coronary artery disease was relatively high in patients with atherosclerotic peripheral vascular disease. And smoking and diabetes seem to be important risk factors of atherosclerotic peripheral vascular disease.
