Sometimes intraorbital foreign bodies lead to unexpected findings. A 16-year old boy was referred due to ocular surface trauma. A conjunctival laceration was detected at the level of the left caruncle with associated left exotropia, reduced adduction as well as a preretinal hemorrhage along the nasal periphery of the fundus. A blow-out fracture of the medial orbital wall was suspected and a CT scan of the orbits was scheduled which revealed the presence of a large intraorbital foreign body. The removal of the intraorbital foreign body (which proved to be a bullet) and precautionary laser photocoagulation along the nasal periphery of the left eye were performed. Ocular surface trauma may reveal unexpected findings, such as an intraorbital foreign body, requiring investigation by a CT scan., Efstathios T. Detorakis, Emmanouil K.

This report describes a case of male patient with metastatic papillary carcinoma of unknown primary origin with unusual high levels of CA 125. Laboratory tests in serum and plasma (urea, creatinine, uric acid, sodium, potassium, total bilirubin, ALT, AST, GMT, ALP, C-reactive protein, and glucose) were normal except C-reactive protein (57.6 mg/l). Computer tomography scan showed tumorous formations situated in the area of both kidneys. According to the literature we performed more detailed laboratory investigation (CEA, CA 125, CA 15-3, CA 19-9, AFP) and we found only serum level of CA 125 significantly elevated (> 600 kU/l). The results of recent studies suggest that CA 125 might be useful as a serum tumor marker also in patients with other carcinomas apart ovarian cancer., Kazuistika popisuje případ pacienta s metastatickým papilárním karcinomem z neznámého zdroje s neobvykle vysokou hodnotou CA 125. Analyty stanovené v séru a plasmě (urea, kreatinin, kyselina močová, sodný kation, draselný kation, celkový bilirubin, ALT, AST, GMT, ALP, C-reaktivní protein a glukóza) byly v referenčním rozmezí kromě C-reaktivního proteinu (57,6 mg/l). Pomocí počítačové tomografie byly prokázány tumorózní útvary v oblasti obou ledvin. V souladu s literaturou bylo provedeno podrobnější laboratorní vyšetření (CEA, CA 125, CA 15-3, CA 19-9, AFP), kde byla prokázána významně zvýšená hladina CA 125 (> 600 kU/l). Výsledky některých studií poukazují na to, že CA 125 by mohl být vhodným nádorovým markerem také u pacientů s jinými druhy karcinomů než s karcinomem ovaria., Eva Klapková, Richard Průša, J.

Mild hyperhomocysteinemia has been established as a new independent risk factor for atherosclerosis and thrombosis. The metabolic syndrome of insulin resistance is associated with a high risk of coronary heart disease. Our objective was to determine if any relationship exists between the metabolic syndrome of insulin resistance in non-diabetic subjects and total serum homocysteine levels. Sixty-six healthy volunteers (33 males and 33 females) were selected from the population of Pilsen. Insulin resistance was measured by the Insulin Suppression Test using Octreotide. Steady-state plasma glucose concentrations at the end of the test period provided a quantitative measure of insulin resistance. Serum homocysteine level was estimated by high-pressure liquid chromatography. Serum folate and vitamin B12 were estimated using commercial kits on an Abbott IMx analyzer. All other laboratory tests were performed by standard methods in a routine biochemical laboratory. Subjects with the highest tertile of steady-state plasma glucose showed a significantly higher body mass index, blood pressure, fasting plasma triglyceride levels, plasminogen activator inhibitor-1 and lower HDL-cholesterol, i.e. an insulin resistance pattern. These subjects had significantly lower serum homocysteine levels compared with non-insulin resistant subjects. The negative association of insulin resistance and serum homocysteine was unexpected. The contribution of plasma folate levels to serum homocysteine levels and serum creatinine was significantly negative and positive, respectively., H. Rosolová, J. Šimon, O. Mayer Jr., J. Racek, T.
