Celem artykułu jest przedstawienie miar zależności opartych na kopulach. Omówione zostały następujące miary: tau Kendalla, rho Spearmana, sigma Schweizera i Wolffa oraz gamma Giniego. Przedstawiono też ogólne aksjomaty miar zgodności i zależności.

Measures of dependence and measures of association based on copulas are presented, including Kendall’s Tau, Spearman’s rho, Schweizer & Wolff’s sigma and Gini’s gamma. General axioms for measures of dependence and measures of association are discussed.

The aim of the study was to analyze inguinal hernia procedures performed by means of Lichtenstein's method.Material and methods. During the period between December, 2004 and December, 2006, 216 patients were subject to surgery due to inguinal hernias. One hundred and three patients were qualified for analysis. Surgical operations were performed in most cases in local anesthesia, in addition to conduction, short intravenous or general anesthesia. Statistical analysis was used for assessing the average incidence split according to their gender and body weights. The length of treatment of patients depending on their gender was estimated and statistical analysis of hernia location was performed.Results. No patient was found to develop early complications, the average operation time was 65 minutes, the average length of treatment for men was 5 days, for women 3 days.Conclusions. Removal of inguinal hernia by the Lichtenstein method was found a good method in treating this disease. This method is convenient for the patient, safe, there are almost no complications and the length of patient's stay in the surgical ward is shortened down.

The study presented a case of a 54-year old woman who developed a fully symptomatic tetany syndrome with tachycardia and Chvostek's (++) sign during the initial 24 hours after subtotal strumectomy. Laboratory parameters demonstrated hypokalemia and hypocalcemia. After the intravenous injection of calcium chloride with simultaneous oral administration of alfacalcidiol, both the calcium and potassium levels returned to normal values.Postoperative tetany is observed in 0.2 to 5.8% of cases, according to literature data. Postoperative hypoparathyroidism may develop after total or subtotal thyroidectomy, as a result of the accidental excision of the parathyroid glands, their damage or vascularization. According to many authors postoperative hypoparathyroidism may result from the ligation of the lower thyroid artery, since these glands, both upper and lower, are supplied by blood in over 90% by the branches of these arteries. Other investigators maintain that tetany may also develop as a result of calcium metabolism disorders. Parathyroid ischemia may also result from pressure of the hematoma formed at the site of the removed thyroid lobes. The above-mentioned complication was probably influenced by a number of factors.
