Peripartum energy metabolism of prolific ewes and their progeny in response to prepartum feeding and litter size.

In late gestation, the increased energy demand to support the rapid fetal growth can induce an acute negative energy balance associated with a high risk of pregnancy toxemia, especially for prolific ewes (carrying two or more fetuses). The current study was conducted to evaluate the effects of dietary energy during the last 6 weeks prepartum on the energy metabolism dynamic responses and the newborn lamb metabolic profile in prolific ewes. Forty-five crossbred (Dorset × Romanov) ewes were randomly assigned to 1 of 3 dietary energy densities: E: 8.

Anterior disc derangement with reduction of the temporomandibular joint: a case report.

Background: Temporomandibular dysfunction involving anterior disc derangement with or without reduction, secondary to posterior ligament insufficiency is typically managed conservatively with success in a majority of patients. When conservative management fails, the next step in the continuum of care is unclear. Platelet-rich plasma injection combined with a 3-week immobilization period may be effective in treating posterior ligament insufficiency following a period of physical therapy.

Doppler studies evaluating the effect of a physical therapy screening protocol on vertebral artery blood flow.

General and isolated cervical positional tests are used to screen for potential vertebro-basilar insufficiency (VBI). There is limited research evaluating vertebral artery blood flow in these positions to justify the rationale of progressive mechanical stress occurring to the arteries. The purpose of the study was to determine vertebral artery blood flow in six cervical positions used in clinical practice.

Bronchoscopy specimens in adults with AIDS. Comparative yields of cytology, histology and culture for diagnosis of infectious agents.

Bronchoscopy specimens from 183 known/suspected acquired immunodeficiency syndrome patients were evaluated for pathogens. In each case, transbronchial biopsies were evaluated and bronchoalveolar lavage material was cultured for viruses, fungi and mycobacteria and examined cytologically. A specimen was considered positive for a pathogen if detected by any one of the methods (TBB or BALC or culture).

Observer variation in assessing spinal curvature and skeletal development in adolescent idiopathic scoliosis.

Accurate measurements of spinal curvature and skeletal development are crucial in planning treatment and assessing curve progression in adolescent idiopathic scoliosis (AIS). An inter-rater agreement trial was undertaken to estimate the reliability of measuring these spinal parameters. Two orthopaedic surgeons and two trained technicians from a scoliosis clinic independently read 30 anteroposterior roentgenograms of AIS patients.
