Pine needle abortions in cattle due to consumption of Pinus ponderosa in Argentina: Case reports.

Two outbreaks of pine needle abortions in cattle are here reported for the first time in Argentina. The cases occurred in Chubut and Neuquén provinces in the Patagonia region, causing 29.6% and 9% of abortions in each herd respectively.

Randomized clinical trial of a single versus a double dose of 13-valent pneumococcal conjugate vaccine in adults 55 through 74 years of age previously vaccinated with 23-valent pneumococcal polysaccharide vaccine.

Introduction: In older adults, prior administration of 23-valent pneumococcal polysaccharide vaccine (PPSV23) blunts the opsonophagocytic antibody (OPA) response to subsequent administration of 13-valent pneumococcal conjugate vaccine (PCV13). To determine whether a higher dose of PCV13 could mitigate this effect in adults 55 through 74 years of age, we compared OPA responses to a double dose of PCV13 in persons previously vaccinated with PPSV23 with responses to a single dose of PCV13 in previously vaccinated persons, and with a single dose in PPSV23 naïve persons.

Methods: Subjects previously vaccinated with PPSV23 were randomly assigned to receive either a single injection or two concurrent injections of 0.

[Experience of an Ethics Committee of a pediatric reference hospital].

Since 1960, there has been a growing interest in the complexity of the ethical problems posed by medical practice. Ever since then, many ethical theories have attempted to support bioethics, setting the necessary grounds for decision making process. The aim of this article is to briefly present the history and working of a pediatric hospital's Assistance Ethics Committee, as well as its evolution from the very beginning.

Short-lived corpora lutea syndrome in anoestrous ewes following 17β-oestradiol or MAP treatments applied before an allogenic sexual stimulation with rams and oestrous ewes.

When induced to ovulate during anoestrus, ewes, does and cows frequently develop a short-lived corpora lutea (SLCL) syndrome associated to lack of previous progesterone. Exogenous progesterone precludes SLCL by blocking oxytocin endometrial receptors, thus inducing normal life-span CL (NLCL). Paradoxically, circa 50% of unprimed ewes do not develop SLCL.

[Health care team and parents' opinion about pediatric patients identification].

Introduction: Patient misidentification continues to be a quality and safety significant issue. The Joint Commission International listed patient identification as the first of ten life-saving patient-safety solutions. Identification wrist bands are the goal in the identification strategy.

LH response of seasonally anovular Corriedale ewes acutely exposed to rams and estrous ewes.

Serial blood sampling before and after exposing four anovular Corriedale ewes to a group of rams and estrous ewes during the non-breeding season revealed a pattern of LH secretion similar to that previously observed in Merinos. Mean LH values doubled (P<0.001) from 0.

Ovariectomy, hindlimb unweighting, and recovery effects on skeletal muscle in adult rats.

Introduction: The effect of female sex hormones on skeletal muscle is unclear. Reports suggest that female sex hormones have an anabolic effect, have no effect, or are detrimental to skeletal muscle.

Methods: To amplify ovarian hormones' potential effects on skeletal muscle, 6-mo-old virgin intact (sham), ovariectomized (OVX), and ovariectomized plus estrogen (OVX + E2) rats were hindlimb unweighted (HLU) for 4 wk.

Large erupting complex odontoma.

An unusual case of erupting complex odontoma is presented.

Surgery of the parotid region: a new approach.

Many disorders of the parotid gland require treatment by subtotal or total parotidectomy. In such situations functional and esthetic complications may arise due to the location of the incisions or from permanent or temporary injuries to the facial nerve. This report describes a modified revision that gives good esthetic and functional results.
