[Reoperation for primary hyperparathyroidism].

While the initial treatment for primary hyperparathyroidism (pHPT), if managed by an experienced surgeon, is almost always successful, reoperations are challenging. Patients are at high risk for complications and the rates of success are plainly below those of primary cervical explorations. In this paper the reasons for failure during initial procedures are reviewed, as are the most important localization procedures and the prerequisites with regard to technical infrastructure as well as personnel, when planning repeat operations for a missed parathyroid adenoma. Provided that a standardized diagnostic and surgical approach is used, the surgeon is experienced, and up-to-date technical equipment is available, permanent normocalcemia following reoperations in pHPT is more frequently achieved than it used to be. The best option to avoid reoperations and associated complications is a successful initial intervention by an experienced surgeon. However, reoperations should always be performed by an experienced surgeon.

Effects of recessive white plumage colour mutation on hatchability and growth of quail hatched from breeders of different ages.

1. A total of 1200 eggs were obtained from two pure line stocks of 'wild' and 'recessive white' quail of the Pharaoh strain (Coturnix coturnix Pharaoh), with two different breeder ages (17 or 34 weeks). The recessive white line was derived from mutant birds, which appeared spontaneously within the wild-type quail colony. 2. The analysis included plumage colour and breeder age as main effects together with their interaction. There were no significant effects for apparent fertility but hatchability of total and fertile eggs was affected by plumage colour variant and breeder age. 3. Body weight was affected by plumage colour throughout the growing period, whereas the differences attributable to breeder age were significant from 21 to 42 d only. 4. Main effects and their interaction were significant for feed conversion ratio until the end of the growing period, except at the age of 7 d for the effect of breeder age. 5. It was concluded that the hatchability and growth performance of the recessive white-type was not as good as the wild-type. The young breeders (17 weeks old) had the best hatchability and subsequent growth performance.
