A cutaneous horn is a general name for cornified material protruding from skin. On the other hand, polydactyly is a common congenital anomaly of the hand and foot which is characterized by extra finger or toe. A cutaneous horn might mimick polydactyly by resembling an extra toe. Hereby, we present a 72-year-old white Caucasian male with an extra toe-like projection on his fourth toe. Initially, polydactyly was suspected, however a cutaneous horn was also considered. The lesion was surgically removed. The histopathological examination of the specimen revealed hyperkeratosis, and thus confirmed the lesion to be a cutaneous horn., Funda Tamer, Mehmet Eren Yuksel, and Literatura
Nevus lipomatosus superficialis is a rare hamartomatous malformation which is composed of ectopic adipocytes in the dermis. It was first reported in 1921 by Hoffmann and Zurhelle. Two clinical forms of nevus lipomatosus superficialis have been described: classical (multiple) and solitary. Classical form of nevus lipomatosus superficialis is usually found on pelvic girdle, trunk, buttocks and thighs as soft, skin colored papules or nodules. It is usually present at birth or it appears in the first two decades of life. The solitary form of lipomatosus superficialis appears as a solitary papule or nodule on the back, scalp and arms of the patients with late onset. The lesions are usually asymptomatic, however some patients may complain about pain and itching. Malignant transformation of nevus lipomatosis superficialis has not been reported yet. Therefore, surgical intervention is only necessary for the patients who have cosmetic concerns. Recurrence after surgical removal is very rare. Perineum is an uncommon localization for nevus lipomatosus superficialis. Hereby, we report a 55-year-old Caucasian female with a 6x5,5x4 cm mass in the perineal region. The patient had cosmetic concerns, therefore she wanted the lesion to be removed surgically. The lesion was surgically removed. The histopathological evaluation of the specimen revealed nevus lipomatosus superficialis. A solitary type of giant nevus lipomatosus superficialis in the perineal region of a patient over the age of 50 is a very rare condition. Even rarely seen, nevus lipomatosus superficialis should be kept in mind in the differential diagnosis of perineal masses., Funda Tamer, Mehmet Eren Yuksel, and Literatura
Navzdory tomu, že standardizace měření sedmi hlavních katalytických koncentrací enzymů je dokončena a referenční metody IFCC na jejím podkladě vytvořené jsou verifikované v kontrolním programu RELA IFCC, situace v rutinních laboratořích vykazuje nedostatečnou míru jejího respektování. Důsledkem je neadekvátně nízká úroveň srovnatelnosti výsledků měření dosažených v různých laboratořích. Příčinou stavu je přetrvávající výroba a používání starších, nestandardizovaných metod existujících vedle sebe na trhu, v portfoliích laboratoří a jako položky hodnocení programů externích hodnocení kvality. K oficiálnímu dosažení proklamovaných cílů harmonizace měření v laboratorní medicíně je zapotřebí existující standardizaci prosadit důsledně do rutinních laboratoří. Ústřední roli zde sehrávají programy externího hodnocení kvality., Despite of fact that standardization of seven basic enzyme measurement is completed and by program RELA IFCC verified, routine laboratories produce results of low level comparability. Producing by manufacturers and use by laboratories of nonstandardized methods are main reason for this bad statement. Another reason is acceptation of non IFCC standardized by providers of external quality programs. If we really wish to reach harmonization of enzyme measurement results, we should introduce standardization more strictly into daily laboratory and manufacturers practices. Important role play here approaches of EQA programs providers., Friedecký B., Kratochvíla J., and Literatura
Anomálie urachu jsou vzácné. V literatuře najdeme práce pojednávající spíše o jednotlivých případech než velké soubory nemocných. Optimální léčba zůstává předmětem debat. Uvádíme kazuistiku 13měsíční dívky s infikovanou cystou urachu. Jedná se o onemocnění s dobrou prognózou při včasně zahájené adekvátní léčbě, může se však manifestovat i jako život ohrožující sepse či peritonitis, pokud dojde k ruptuře cysty., Urachal anomalies are rare. Literary data include case reports, studies analysing data from large groups are not available. Optimal treatment remains a matter of debate. The disease has a good prognosis when adequate treatment is initiated early. It can however also manifest with a lifethreatening sepsis or peritonitis. We report a case of 13-month-old girl with infected urachal cyst., Jana Horáková, Jan Starczewski, Miloš Fiala, Vladislav Smrčka, Jiří Kubále, Aleš Petřík, and Literatura
The analysis of data of 97 children with brain tumors of supratentorial localization was carried out. To estimate treatment efficacy was used a rating scale of quality of life. It was determined that the quality of life of patients with brain gliomas depends on localization of neoplastic process, histological properties of tumor, preoperative neurologic deficit and the patient’s compensated condition., Jamshid Ashrapov, and Literatura
