BACKGROUND: The end-tidal carbon dioxide tension(ETCO2) is defied as a partial pressure of carbon dioxide at the end of an exhaled breath.)he purpose of this study is to determine the correlation between ETCO2 and arterial carbon dioxide tension(PaO2) in nonintubated abated patients with respiratory distress in emergency department(ED). METHODS: A prospective non-blind study was performed in ED of our university hospitals. Participants included all nonintubated adult patients with respiratory distress requiring arterial blood gas analysis. ETCO2 was measured with a capnography monitor during tidal volume breathing. ETCO2 were recoreded at the time of arterial blood gas sampling. The correlation between ETCO2 and PaCO2 was analysed in all patients and in subgroups by simple linear regression. RESULTS: Sixty patients were enrolled. In all patients, ETCO2 was 5.72mmHg lower than PaCO2 and correlated well with PaCO 2(r2=0.716). ETCO2 correlated best with PaCO2) in patients who were either acidotic or non-smoking. CONCLUSION: ETCO2 correlate well with PaCO2 in nonintubated patients with respiratory distress in ED. ETCO2 may be sufficient to reflect PaCO2 in selected patients and obviate the need far repeat arterial blood gas determination.

Ethylene glycol is a sweet-tasting liquid with industrial use as a solvent or as a starting reagent in chemical processes. Physicians are familiar with ethylene glycol because it is the major component of many antifreeze solutions and is taken in suicide attempts or, more often inadvertency. its metabolites may cause severe intoxication. Unfortunately, its metabolites are highly toxic and require rapid treatment Treatment involves correction of metabolic acidosis, ethanol administration and enhancement of elimination. The most commonly used elimination technique is hemodialysis We describe an 21-year-old man with acute renal failure due to ingestion of antifreeze that contained ethylene glycol. He was transferred to our hospital because of aggressive management The recovery of our patient with severe ethylene glycol intoxication illustrates that aggressive and early treatment can prevent mortality and morbidity.

Biliary cystadenomas are very rare cystic neoplasms usually arising from the intrahepatic bile ducts. The majority of patients are middle-aged women who present with abdominal discomfort and/or a palpable mass. The diagnosis was performed using several methods such as abdominal ultrasonography, computed tomography, percutaneous cholangiography or endoscopic retrograde cholangiopancreatography, and showed multiloculated cystic tumors with multiple internal septation. But confirmatory diagnosis was done by surgical pathology. Because the prognosis is comparatively better than after complete resection and the cystadenoma is warranted to avoid malignant change, early detection and surgical resection must be needed. We have experienced two cases, 30 and 50 year old females, which presented with nonspecific abdominal pain and dyspepsia. They were diagnosed as having intrahepatic biliary cystadenoma histopathologically which was confirmed after surgical resection. We report two cases of intrahepatic biliary cystadenoma with a review of literature.

BACKGROUND/OBJECFTIVES: The effect of St. John's Wort extract (SJW) on MG-63 cell proliferation and trabecular bone loss induced by ovariectomy was examined. MATERIALS/METHODS: Proliferation, expression of estrogen receptor (ER) alpha and ER beta, and gene expressions of osteoprotegerin (OPG), osteocalcin (OC) and alkaline phosphatase (ALP) were examined in MG-63 cells treated with or without SJW. Ovariectomized rats were treated with SJW at the dose of 100 or 200 mg/kg/day, beta-estradiol-3-benzoate (E2), or vehicle only (OVX-C), and sham operated rats were treated with vehicle only (Sham-C). Serum ALP and C-telopeptide (CTX), and femoral trabecular bone loss were examined. RESULTS: SJW increased MG-63 cell proliferation and expression of ER alpha and ER beta, and positive effect was shown on gene expressions of ALP, OC and OPG. SJW also showed estrogen like effect on bone associated with slowing down in trabecular bone loss. Histopathology by H&E showed rats treated with SJW displayed denser structure in metaphyseal region of distal femur compared with rats in OVX-C. SJW was shown to reduce serum CTX in OVX rats. CONCLUSION: The present study provides new insight in preventing estrogen deficiency induced bone loss of SJW and possibility for its application in bone health supplement.
