BACKGROUND The effects of treatment of children with longitudinal radial deficiency are generally evaluated by measuring grip and pinch strength and joint mobility. Insight into limitations of activities of children with radial deficiency is scarce. In this study, we used standardized instruments to assess impairments in hand function and activity(More)
A 32-year-old healthy woman developed thyrotoxicosis while taking capsules that contained ashwagandha herbal extract for symptoms of chronic fatigue. She was not taking any other remedies or medications. During the first few weeks, she took the capsules only occasionally without any symptoms, but after increasing the dose, she experienced clinical symptoms(More)
59 relatives with a family history of hereditary chemodectoma have been successfully screened by means of radionuclide scintiangiography. The findings showed a close correlation with selective roentgenangiography. 3 asymptomatic patients with chemodectoma were revealed by these methods without causing discomfort to the group involved.
PURPOSE For treatment evaluation of children with radius deficiencies (RDs), standardized assessment of hand function in performing activities is required. Instruments to measure hand function have been developed for other diagnoses. The current study aimed to find additional evidence for validity, reliability, and usefulness of these instruments for(More)
Arterial catheterization is one of the most frequently performed inpatient diagnostic and therapeutic procedures in the development countries. Complications may occur after any catheterization from inadequate hemostasis, particularly in the setting of aggressive anticoagulation. This study suggests that microcrystalline chitosan (MCCh) sealant installation(More)
AIMS In spite of increasing reuse of disposable catheters, there are few scientific data on potential viral transmission and infection after reuse. To determine the theoretical risk of virus transmission during reuse of catheters an in vitro study was performed using an RNA virus (echovirus-11) and a DNA virus (adenovirus-2). METHODS AND RESULTS After(More)
A prototype of a totally implantable vascular catheter-port system was evaluated on its design using three animals of different species. The catheter was placed either intravenously or intra-arterially, and connected to the port which was retained outside the body. Parameters used for design evaluation or functionality testing were focused on the use and(More)
Various totally implantable drug delivery systems from single access ports to micropumps are now available for administration of repeated boluses, and continuous or programmable infusions. In this respect, emphasis is given to a relatively cheap, totally implantable system for self-administering intraspinal opiates in the treatment of cancer pain. The SECOR(More)
In order to explore the influence of an isolated congenital hand malformation on psychomotor development, we performed an exploratory, observational study on 18 children with triphalangeal thumbs. The investigative procedure consisted of a hand function examination, a semi-structured interview with the mother about the development of the child, the(More)
