Cerebral venous angomas are a rare form of intracranial vascular malformation and first reported by Wolf in 1967. The characteristic angiographic appearance of venous malformation is a local network of small veins that converged centrally into a single large drainage vein. The CT findings are linear or curvilinear enhancement after administration of contrast media. The authors present a case of venous angiomatosis of the both hemisphere combined with dural arteriovenous malformations demonstrated by the carotid angiography and bran CT, with clinical presentation of status epilepcus and following left hemiplegia due to cerebral infarction.

Perillae Herba has been traditionally used for the sedation in the oriental countries. Therefore, this study was conducted to determine whether Perillae Herba ethanol extract (PHEE) enhances pentobarbital-induced sleeping behaviors in animals. In addition, the possible mechanisms are demonstrated. PHEE (12.5, 25 and 50 mg/kg. p.o.) reduced the locomotor activity in mice. PHEE reduced sleep latency and augmented the total sleep time in pentobarbital (42 mg/kg, i.p.)-induced sleep in mice. Furthermore, the number of sleeping mice treated with sub-hypnotic pentobarbital (28 mg/kg, i.p.) increased. PHEE (50 mg/kg. p.o.) decreased the sleep/wake cycles and wakefulness, and increased total sleeping time and NREM sleep in electroencephalogram (EEG) of rats. In addition, PHEE (0.1, 1.0 and 10 µg/ml) increased the intracellular Cl⁻ level through the GABA receptors in the hypothalamus of rats. Moreover, the protein of glutamate decarboxylase (GAD) was overexpressed by PFEE. It was found that PHEE enhanced pentobarbital-induced sleeping behaviors through GABA(A)-ergic transmissions.

Obstructive jaundice produced by periportal tuberculous adenitis in the absence of pulmonary tuberculosis is quite rare. We are reporting the case of a 58-year-old woman who presented with constitutional symptoms and biochemical evidence of biliary tract obstruction. By abdominal sonogram and CT scan, a mass around the head of pancreas and periportal area was detected. The ERCP showed fistula connected proximal common bile duct to lymph node. The patient underwent laparotomy and recognized tuberculous adenitis of periportal lymph node which caused biliary tract obstruction with fistula.

It has been known that RA, one of major constituents of Perilla frutescens which has been used as a traditional folk remedy for sedation in oriental countries, shows the anxiolytic-like and sedative effects. This study was performed to know whether RA may enhance pentobarbital-induced sleep through γ-aminobutyric acid (GABA)(A)-ergic systems in rodents. RA (0.5, 1.0 and 2.0 mg/kg, p.o.) reduced the locomotor activity in mice. RA decreased sleep latency and increased the total sleep time in pentobarbital (42 mg/kg, i.p.)-induced sleeping mice. RA also increased sleeping time and number of falling sleep mice after treatment with sub-hypnotic pentobarbital (28 mg/kg, i.p.). In electroencephalogram (EEG) recording, RA (2.0 mg/kg) not only decreased the counts of sleep/wake cycles and REM sleep, but also increased the total and NREM sleep in rats. The power density of NREM sleep showed the increase in δ-waves and the decrease in α-waves. On the other hand, RA (0.1, 1.0 and 10 μg/ml) increased intracellular Cl− influx in the primary cultured hypothalamic cells of rats. RA (p.o.) increased the protein expression of glutamic acid decarboxylase (GAD(65/67) ) and GABA(A) receptors subunits except β1 subunit. In conclusion, RA augmented pentobarbital-induced sleeping behaviors through GABA(A)-ergic transmission. Thus, it is suggested that RA may be useful for the treatment of insomnia.

OBJECTIVES: To evaluate the clinical significance of abnormal bronchi originating from the trachea or main bronchi. METHODS: 21 patients (male:female ratio, 13:8; mean age, 58.2 years, range 34-77), who were diagnosed with major tracheobronchial anomalies by bronchoscopy from January 2001 to March 2005, were enrolled in this study. The anomalous bronchi consisted of 13 tracheal bronchi and 8 cardiac accessory bronchus. The clinical features, bronchoscopic findings, and outcomes were analyzed retrospectively. RESULTS: Common symptoms, including hemoptysis, cough and dyspnea, resulted from the underlying lung disease regardless of the bronchial anomalies. In this series of 13 tracheal bronchi, 7 cases originated from the trachea within 1cm of the carina (carinal type) and 6 cases originated at a higher level(tracheal type). Most patients had favorable outcome with conservative treatment for the underlying lung disease. CONCLUSION: Most tracheobronchial anomalies are found incidentally in the process of diagnosing lung disease. The clinical outcome of patients with a bronchial anomaly depends on the underlying lung disease.

BACKGROUND/AIMS: Femoral fracture occurs most often in elderly patients and is highly associated with medical problems such as acute kidney injury (AKI); however no reports of AKI in femoral fracture patients have been published. This study was performed to identify risk factors and the clinical course of AKI in patients with femoral fracture. METHODS: We retrospectively evaluated the medical records of 110 patients with femoral fracture between November 2006 and December 2011 at Uijeongbu St. Mary's Hospital. We investigated the incidence and clinical course of AKI in femoral fracture patients and compared the clinical findings between AKI and normal kidney function (NKF) groups. RESULTS: Of the 110 femoral fracture patients, AKI was observed in 19 (17.3%). The peak serum creatinine level in patients with AKI was 2.59 +/- 1.57 mg/dL. Two of 19 patients with AKI died and two progressed to chronic kidney disease. When compared to the NKF group, the AKI group had a higher incidence of elevated lactate dehydrogenase (LDH) (63.2% vs. 34.1%, p = 0.020), erythrocyte sedimentation rate (ESR) (31.6% vs. 6.6%, p = 0.008), and C-reactive protein (57.9% vs. 46.2%, p = 0.042). The AKI group also had a longer hospitalization duration, and more patients were prescribed an angiotensin-converting-enzyme (ACE) inhibitor than in the NKF group. Multivariate analysis demonstrated elevated LDH, ESR and ACE inhibitor prescriptions as independent risk factors for AKI in patients with a femoral fracture. CONCLUSIONS: The incidence of AKI in patients with a femoral fracture was 17.3%, and AKI was associated with a longer clinical course. We recommend monitoring of laboratory findings and medications and early management to reduce the morbidity of patients with AKI.

Emphysematous pyelonephritis (EPN) is a life-threatening infection characterized by the formation of gas. Complications of EPN include septic shock, acute renal failure, and disseminated intravascular coagulation. Spontaneous subcapsular hematoma (SCH) has also been reported as a rare complication of EPN, although there have been no reports to date of this occurring prior to the presentation of EPN. We report a case of EPN that initially presented as spontaneous SCH. The patient was admitted for left flank pain, and initial computed tomography revealed SCH without any air shadows. Laboratory findings and clinical symptoms suggested the presence of urinary tract infection and the patient was started on antibiotics. Fever developed 24 hours after admission. On follow-up computed tomography 7 days later, EPN was newly observed, and a percutaneous drain was inserted. Blood, urine, and drainage fluid cultures all revealed growth of extended-spectrum beta-lactamase-negative Escherichia coli.

BACKGROUND: This study evaluates the bacterial pathogens of Ventilator-associated pneumonia (VAP) in a tertiary referral hospital. METHODS: A total of 109 bacterial pathogens from 91 adult patients with VAP, who were admitted to the medical intensive care unit from January 2008 to December 2009, were examined. Clinical characteristics, bacterial pathogens, and resistance profiles were analyzed. RESULTS: Staphylococcus aureus (44%) was the most frequently isolated. Acinetobacter baumanii (30%), Pseudomonas aeruginosa (12%), Stenotrophomonas maltophilia (7%), Klebsiella pneumoniae (6%), and Serratia marcescens (2%) were isolated from the transtracheal aspirates or bronchoalveolar lavage in patients with VAP. There was no significant difference of bacterial pathogens between early and late onset VAP. All isolated S. aureus were methicillin resistant S. aureus; the imipenem resistance rate of A. baumanii was 69%. CONCLUSION: The two most frequent pathogens of VAP were S. aureus and A. baumanii. There were no pathogenic differences between early and late onset VAP.

Poria cocos is a well-known traditional Chinese traditional medicine (TCM) that grows around roots of pine trees in China, Korea, Japan, and North America. Poria cocos has been used in Asian countries to treat insomnia as either a single herb or part of an herbal formula. In a previous experiment, pachymic acid (PA), an active constituent of Poria cocos ethanol extract (PCE), increased pentobarbital-induced sleeping behaviors. The aim of this experiment was to evaluate whether or not PCE and PA modulate sleep architectures in rats as well as whether or not their effects are mediated through GABA(A)-ergic transmission. PCE and PA were orally administered to individual rats 7 days after surgical implantation of a transmitter, and sleep architectures were recorded by Telemetric Cortical encephalogram (EEG) upon oral administration of test drugs. PCE and PA increased total sleep time and non-rapid eye movement (NREM) sleep as well as reduced numbers of sleep/wake cycles recorded by EEG. Furthermore, PCE increased intracellular chloride levels, GAD65/67 protein levels, and alpha-, beta-, and gamma-subunits of GABA(A) receptors in primary cultured hypothalamic neuronal cells. These data suggest that PCE modulates sleep architectures via activation of GABA(A)-ergic systems. Further, as PA is an active component of PCE, they may have the same pharmacological effects.
