Abstract

The aim of this study was to determine several obstetric and neonatal parameters in the Maine Coon breed. The birth data of Maine Coon breeding population were collected of 52 litters from different households using a questionnaire. Significant relationships between various outcomes and the relevant predictors were assessed by multiple linear regression or logistic regression, as appropriate. The overall mean gestation length was 65.5±1.32 days. Larger litter size was associated with shorter gestation lengths (p<0.01). Mean litter size was 5.3±2.3 kittens. The weight of kittens born alive (overall mean 119.6±18.4 g) increased with prolonged gestation lengths (p<0.01) and decreased with larger litter sizes (p<0.01). In the analyzed group of kittens, 12.5% were stillborn. The expulsion intervals varied widely. The duration of the first stage of labour was less than 2h in 82.9% of the cats. The interval between the birth of the first and the last kitten was less than 6h in 99.3% of the cats, and it exceeded 6 h in only 2 cats. The present results can be used to develop references values and reliable assistance protocol for assessing the parturition in the Maine Coon to protect the queen and reduce perinatal losses.

Abstract

Incidence of colonic atresia in living infants ranges from 1:5,000 to 1:60,000 (average 1:20,000). It constitutes 1.8 to 15% of all cases of atresia of the gastrointestinal tract. In 58.56–75% of all cases is right-sided. We aim, through the presentation of two cases of colonic atresia which we encountered and after systematic research of the current literature, at addressing three major issues: diagnostic approach, operative strategy and management of the prognostic parameters of the colonic atresia. The common parameter in these two cases was the early diagnosis, which played a significant role in the uncomplicated postoperative course. The first case was a type I sigmoid atresia. Contrast’s escape during contrast enema examination due to accidental rupture of the distal part of the colon led to diagnosis. Side-to-side anastomosis, restoration of the rupture and a central loop sigmoidostomy were urgently performed. The second case was a type III atresia at the level of the ascending colon, which was early diagnosed via pregenital ultrasonography, in which colonic dilation was depicted. Restoration of the intestinal continuity early after birth was performed at a time. In conclusion, we believe that early diagnosis, selection of the appropriate operative strategy and prompt recognition of potential post-operative complications, especially rupture of the anastomosis, contribute to the optimization of the prognosis in patients with colonic atresia.
