Two-Way Fluid–Gas Exchange Syringe for Postvitrectomy Patients in Outpatient Setting Pars plana vitrectomy is a surgical procedure for the treatment of diseases such as rhegmatogenous retinal detachment, proliferative diabetic retinopathy, macular hole, and macular pucker (also called epiretinal membrane). In clinical medical practices, complications such as postvitrectomy vitreous hemorrhage, ...

BACKGROUND Growth hormone (GH) is used to treat growth hormone deficiency (GHD, adult and paediatric), short bowel syndrome in patients on a specialized diet, HIV-associated wasting and, in children, growth failure due to a number of disorders including Turner's syndrome and chronic renal failure, and in children born small for gestational age. Different brands and generic forms of recombinant ...

BACKGROUND Lack of information on the HIV epidemic among men who inject drugs (MWID) in northwestern Vietnam, a remote area, may hamper national efforts to control the disease. We examined HIV prevalence, needle-syringe sharing behaviors, and associated factors among MWID in three areas of northwestern Vietnam. METHODS We used descriptive analysis to report the characteristics, frequency of r...

This prospective, nonblinded study, comparing jet injection with needle-syringe injection of lidocaine in performing digital blocks, tested the hypothesis that jet injection can be used effectively as a less painful way to perform digital blocks. Twenty-four adult patients with injuries of the middle or distal phalanges of the fingers received digital blocks using a jet injector on one side of ...

OBJECTIVE The purpose of this prospective, randomized, blinded study was to compare the pain of injection and post-injection pain of the AMSA injection using the computer-assisted Wand Plus injection system versus a conventional syringe. STUDY DESIGN Using a crossover design, 40 subjects randomly received 2 blinded AMSA injections using the Wand Plus system and a conventional syringe, at 2 se...

Active drug users—whom I here roughly categorize as habituated, addicted, or dependent (HAD) users who are not currently inclined to abandon their use of such drugs1—may desire individually or collectively to assert themselves in the wider social world of work and social policy. Drug-dependent individuals may seek work in harm reduction centers or as custodians, accountants, or doctors. Activis...

It has been the experience of this laboratory that the lead hydroxide stain of Watson (1) gives excellent results in increasing contrast in thin sections of tissue, but that the stain is inconvenient to use because on contact with air it forms an insoluble precipitate which contaminates both the stored solution and the sections. 1 Contamination introduced in transferring the solution from the s...

To generate complete 3-D maps of extracellular ion current patterns around insect ovarioles without removing the sample and chamber from the recording equipment, it was necessary to design a chamber permitting complete rotation of the tissue. While suction pipets have been used in previous studies to orient the tissue (1), their use can significantly disturb extracellular ionic gradients if an ...
