RESUMEN

BACKGROUND/AIMS: Endemic nephropathy (EN) is a chronic tubulointerstitial disease. Strong association between EN and urothelial carcinoma was noted as early as 40-50 ago. The aim of the study was to determine and compare specific mortality and morbidity of renal pelvis and ureter (upper urothelium) carcinoma (UUC) among Croatia as a whole, Brod-Posavina County, and Croatian endemic area. METHODS: Data on UUC mortality and morbidity were analyzed. Indirect standardization was employed on data comparison by calculating standardized mortality ratio and morbidity ratio. RESULTS: Our study results showed the specific mortality rate in the endemic area to be 26.3-fold and 7.3-fold the rate recorded in Croatia and Brod-Posavina County, respectively. The mean standardized mortality ratio obtained by indirect standardization yielded an 8-fold and 32-fold risk of death from UUC in the endemic area vs. Brod-Posavina County and Croatia as a whole, respectively. These data revealed the specific morbidity in the Croatian endemic area and Brod-Posavina County to be 13.95-fold and 3.78-fold the morbidity recorded at the national level, respectively. The standardized morbidity ratio also showed the risk of developing UUC in the Croatian endemic area to be 3.75-fold the risk in Brod-Posavina County and 16.4-fold the risk in Croatia. CONCLUSIONS: These results showed that specific mortality and morbidity as well as standardized morbidity ratio and standardized mortality ratio were higher in Croatian endemic area than in Brod-Posavina County and Croatia.

RESUMEN

Colorectal carcinoma (CRC) is a major public health problem as the third leading malignant tumor in men and fourth in women in Croatia. Prognosis and treatment greatly depend on tumor stage at the time of detection. Therefore, the National Program of Colorectal Carcinoma Early Detection has been performed since 2007. The aim is to present the response rate, colonoscopy findings and number of newly detected CRC cases in Brod-Posavina County. During five years of the National Program performance, 28 CRC cases were detected in Brod-Posavina County, with the 3.3% rate of carcinoma detection. The majority of CRC cases were found in the 50-64 age group. The response rate in the County was low (20.4%), corresponding to the national rate but far from the recommended one. Such a result could be attributed to the low level of awareness in the population at large, complex testing technique for general population, fear from disease detection and from colonoscopy as a diagnostic procedure. Note should be made of the underestimated role of family physicians; their involvement in the National Program should certainly result in better response rate in our County as well as at the national level.

RESUMEN

BACKGROUND: Hypertension is not considered to be a characteristic of endemic nephropathy (EN). Recent observations suggested that it might be more prevalent than it was reported before. AIM: The aim of our study was to analyze prevalence, treatment and control of hypertension in a Croatian endemic area. METHODS: In the present cross-sectional study, 1,602 farmers were enrolled, 1,246 from EN and 356 from control villages. Epidemiological and medical histories were taken and clinical and laboratory examinations performed for kidney function. Blood pressure was measured following the ESH/ESC guidelines. RESULTS: The prevalence of hypertension in EN villages was higher than in control (50.8 vs. 46.5%, p = 0.005). There was no difference in overall treatment, control of all and treated hypertensives between the villages. In all villages, women were treated more than men (EN 41.6 vs. 28.4%, p < 0.001; control 46.4 vs. 27.3%, p < 0.001), but better control of treated was achieved in men (EN 24.7 vs. 17.4%, p = 0.002; control 29.6 vs. 15.5%, p = 0.002). Women had lower income and level of education than men (p < 0.01). CONCLUSION: Hypertension is highly prevalent in endemic villages. In all villages, men had better blood pressure control despite being treated less. This finding could be explained by poorer education and income in women.

RESUMEN

BACKGROUND/AIMS: An epidemiological survey of endemic nephropathy (EN) was performed in endemic Croatian areas and the current prevalence was compared to that reported for the same villages several decades ago. METHODS: A total of 2,487 adult farmers from 6 endemic villages and 3 non-endemic villages were enrolled. An extensive epidemiological questionnaire, clinical examination and laboratory analyses of blood and urine were performed. According to the modified WHO criteria, participants were classified into diseased, suspected of having EN, and those at risk of developing EN. RESULTS: The overall prevalence of EN in the Croatian areas was 1.0%, ranging between 0.3 and 2.3% in different villages. Those suspected of having EN amounted to 3.9%. In the endemic villages a decreasing trend in the prevalence of EN was observed comparable to the results obtained in previous surveys. It is interesting to note that no EN patients were recorded in the endemic village of Dubocac. CONCLUSION: The prevalence of EN in the endemic Croatian areas appears to be decreasing. For the first time, we failed to detect any EN patients in a village that was previously considered endemic, which might indicate that EN is diminishing.

RESUMEN

We are reporting on a household outbreak of measles, in which cases of simultaneous measles and chickenpox infection occured in children of a family who resided in Italy during the incubation period (June 2011). In three children, fever and generalized confluent macular rash were the dominant symptoms. Serology testing revealed simultaneous measles and chickenpox infection in four children.
