Cyclopia: An epidemiologic study in a large dataset from the International Clearinghouse of Birth Defects Surveillance and Research

Cyclopia is characterized by the presence of a single eye, with varying degrees of doubling of the intrinsic ocular structures, located in the middle of the face. It is the severest facial expression of the holoprosencephaly (HPE) spectrum. This study describes the prevalence, associated malformations, and maternal characteristics among cases with cyclopia. Data originated in 20 Clearinghouse (ICBDSR) affiliated birth defect surveillance systems, reported according to a single pre-established protocol. A total of 257 infants with cyclopia were identified. Overall prevalence was 1 in 100,000 births (95%CI: 0.89-1.14), with only one program being out of range. Across sites, there was no correlation between cyclopia prevalence and number of births (r=0.08; P=0.75) or proportion of elective termination of pregnancy (r=-0.01; P=0.97). The higher prevalence of cyclopia among older mothers (older than 34) was not statistically significant. The majority of cases were liveborn (122/200; 61%) and females predominated (male/total: 42%). A substantial proportion of cyclopias (31%) were caused by chromosomal anomalies, mainly trisomy 13. Another 31% of the cases of cyclopias were associated with defects not typically related to HPE, with more hydrocephalus, heterotaxia defects, neural tube defects, and preaxial reduction defects than the chromosomal group, suggesting the presence of ciliopathies or other unrecognized syndromes. Cyclopia is a very rare defect without much variability in prevalence by geographic location. The heterogeneous etiology with a high prevalence of chromosomal abnormalities, and female predominance in HPE, were confirmed, but no effect of increased maternal age or association with twinning was observed.Fil: Orioli, Ieda Maria.

The evidence of contaminants in dairy products

U pogledu zdravstvene ispravnosti namirnica danas se u svijetu poglavito govori o razini njihova zagađenja odnosno nalazu štetnih tvari koje mogu ugroziti čovječje zdravlje. Uporaba veterinarskih lijekova u terapijske svrhe i njihov dodatak stočnoj hrani te uporaba kemijskih sredstava u zaštiti bilja najznačajniji su putovi kemijskog zagađenja mlijeka i mliječnih proizvoda. Razina spomenutih zagađenja ovisi o mogućnostima uporabe tih sredstava u poljoprivrednoj, stočarskoj i veterinarskoj praksi. Zdravstvena ispravnost mliječnih proizvoda ovisi i o nazočnosti patogenih mikroorganizama, a i o suvremenim spoznajama o nutricionističkoj vrijednosti pojedinih sastojaka.In the context of the wholesomeness the foodstuffs today we talk mostly about the quantity of different food contaminants which can cause the disturbances of human health. The use of veterinary drugs for therapeutic purposes and their addition to the animal feed, the use of pesticides and other chemicals in the plant production are the most important ways of milk and dairy products contamination. The quantity of such pollution depends on the possibilities of using this agents in agriculture, animal breeding and veterinary practice. The wholesomeness of dairy products depends on the evidence of pathogenic microorganisms as well as on the nutrition value of the composition of fooodstuffs
