Development of eye-hand coordination in typically developing children and adolescents assessed using a reach-to-grasp sequencing task.

Eye-hand coordination is required to accurately perform daily activities that involve reaching, grasping and manipulating objects. Studies using aiming, grasping or sequencing tasks have shown a stereotypical temporal coupling pattern where the eyes are directed to the object in advance of the hand movement, which may facilitate the planning and execution required for reaching. While the temporal coordination between the ocular and manual systems has been extensively investigated in adults, relatively little is known about the typical development of eye-hand coordination.

Influence of a negative sestamibi scan on the decision for parathyroid operation by the endocrinologist and surgeon.

Background: It has been observed that negative sestamibi scans may impact practice patterns in patients with primary hyperparathyroidism. However, there are no published data on the issue. The objective was to elucidate the influence of negative sestamibi scans on referrals by endocrinologists for parathyroidectomy and surgeon decision-making.

Case for diagnosis. Puncture lesions with foreign body in the feet.

Patients presenting with plantar puncture wounds with presence of foreign bodies are treated in emergency departments, dermatology and orthopedic clinics. The clinical features of these lesions are rarely cited in journals and textbooks of dermatology. We report a case of foreign body in the plantar surface of the foot, in which clinical history and dermatological examination were decisive for the diagnosis.
