Negligência unilateral pós-acidente vascular encefálico: atuação da Terapia Ocupacional

Unilateral Neglect Syndrome is one of the consequences of cerebral vascular accident (CVA) generally following right parietal lobe lesion, leading to the impairment of perceptive visual, spatial and attention functions. The patient affected does not realize the environmental stimuli on the contralesional hemibody. Occupational therapy plays an important role in caring for this patient, seeking the recovery of perception, attention and social engagement. This study aimed to describe and evaluate the results of occupational therapy intervention and treatment in a single Unilateral Neglect Syndrome post CVA patient. Data were obtained from a survey of the patient’s medical records and interviews of his therapist and caretaker. The analysis of the patient’s medical records and his therapist’s report showed that the patient responded satisfactorily to treatment, presenting a decrease of the left unilateral neglect at the end of the study period. The favorable outcome of the patient outlined the relevance of evaluating the effects of Occupational Therapy interventions for clinical unilateral neglect syndrome.

Endoscopic endonasal approach for pituitary adenoma: surgical complications in 301 patients

The authors investigate the complications of transnasal transsphenoidal endoscopic surgery in the treatment of 301 patients with pituitary adenomas. A retrospective analysis of complications in 301 patients submitted to transsphenoidal transnasal endoscopic surgery at the General Hospital of Fortaleza, Brazil between January 1998 and December 2009. The complications were divided in two groups: anatomical (oronasofacial, sphenoid sinus, intrasellar, suprasellar and parasellar) and endocrinological complications (anterior and posterior pituitary dysfunctions). We observed a total of 81 complications (26.9%) in our series. Anatomical complications occurred in 8.97% (27 cases): 8 CSF postoperative leaks (2.6%), 6 cases (1.9%) of delayed nasal bleeding, 5 cases (1.6%) of sphenoidal sinusitis, 3 cases (0.9%) of carotid artery lesion, 2 cases of meningitis (0.6%) and one case (0.3%) of each of the uncommon following complications: intrasella-suprasella hematoma, pontine hematoma and chiasmaplexy. Endocrinological complications occurred in 17.9% (54 cases): additional postoperative anterior lobe insufficiency in 35 cases (11.6%), and postoperative diabetes insipidus in 19 cases (6.3%). In our series, 3 cases of deaths (not directly related to the procedure) were also observed. Endoscopic transsphenoidal surgery represents an effective option for the treatment of patients with pituitary tumor. Complications still occur and must be reduced as much as possible. Successful endoscopic pituitary surgery requires extensive training in the use of an endoscope and careful planning of the surgery. Additional improvement can be expected with greater experience and new technical developments.

Do Thyroid Ultrasonographic Features Change According to Age in Euthyroid Dogs?

The thyroid gland was assessed by ultrasound in healthy euthyroid mixed-breed medium size dogs in different age groups. The objective was to verify ultrasonographic imaging patterns in these groups, as well as to identify possible changes in imaging features resulting from ageing. Thirty dogs - 10 young (<1 year), 10 adult and 10 elderly - without clinical signs or history of thyroid gland disease with complete blood count and thyroid function tests within the reference values were evaluated. Each thyroid lobe was examined by ultrasound for shape, size, echogenicity and echotexture. The analysis of echogenicity and echotexture was made by histogram. Thyroid volume was estimated by the equation for ellipsoid (length x width x height) pi/6. The thyroid volume of the young dogs in this study had a tendency to be higher than in adult dogs (P = 0.068) and older dogs (P = 0.120). The height of the thyroid lobe in the longitudinal plane was significantly higher (P = 0.026) in young dogs compared with the other dogs. The echotexture and echogenicity had no significant differences between groups, but the echogenicity was greater in older dogs. The results point out that ultrasound imaging of the thyroid volume is influenced by age in euthyroid dogs.

Efeito do diabetes sobre o crescimento puberal da próstata de rato: avaliação hormonal, imunocitoquímica e bioquímica

Adequate testosterone levels are necessary for the development, growth and maintenance of the male reproductive system. Testosterone deficiency is common in men with diabetes in whom it may contribute to impaired performance, with consequent reduction of the activity of the androgen regulated organs, such as the prostate. However, little attention has been given to the plasma dihydrotestosterone (DHT) level, the most potent androgen, nor to the expression of the androgen receptor (AR), insulin-like growth factor type I (IGF-1) and receptor (IGF-1R) in target tissues. Here, we investigated the effect of type I diabetes mellitus on DHT plasma levels and on prostate AR, IGF-1 and IGF-1R expression during rat pubertal growth. Diabetes was induced in prepubertal male rats through administration of streptozotocin (STZ; 40 mg/kg). Diabetic, diabetic treated with insulin, and age-matched control animals were killed by overdoses of pentobarbital. The ventral prostatic lobe (VP) was dissected, weighed and processed for immunohistochemistry for AR, IGF-1 e IGF-1R; plasma T and DHT levels were also determined. Hyperglycemia at puberty reduced VP weight gain to about 50% and plasma T level to about 80% of the control levels. In contrast there were no changes in plasma DHT levels. Insulin replacement restored the VP weight gain, but not the plasma T levels, which remained 90% below the ones of controls. Immunohistochemistry showed that AR, IGF-1 and IGF-1R expression in the prostate epithelial cells did not change with hyperglycemia or insulin replacement. Thus, the AR expression in the prostate epithelial cells appears to be regulated by DHT, and to a minor extent it also controls glandular growth
