Objective: To design inexpensive, easily fabricated stoma buttons for post-laryngectomy patients with stomal stenosis and patients who require prolonged tracheotomy.   Methods:        Design: Surgical Instrumentation Setting: Tertiary Government Hospital Participants: Tracheostoma buttons fabricated from 3 or 5 cc disposable plastic syringes were tested on two post-laryngectomy patients with stomal stenosis and a tracheotomized patient with bilateral vocal cord paralysis.   Results: The tracheostoma buttons were inexpensive and relatively easy to fabricate. They were easily inserted and well tolerated by all three patients, compared to previously-used commercially-available tracheotomy tubes.   Conclusion: In a developing country setting, improvised tracheostoma buttons made from disposable plastic syringes may be viable alternatives to commercially-available stoma buttons or tracheotomy tubes. Clinical trials on more subjects should be conducted to assess parameters for use and long-term efficacy and safety issues.   Keywords: stomal stenosis, tracheostoma/stoma button

Plastic Culture Dish

A versatile, inexpensive, easily constructed suction electrode system is described that can be used for routine exercises by the student on, or for demonstrations of, the electrophysiology of frog sciatic nerve and gastrocnemius and sartorius muscles. A disposable plastic syringe and a disposable pipette with Ag-AgCl wire comprise the suction electrode. Six readily manipulable electrodes are installed in the walls of the Plexiglas preparation bath, and an arbitrary number of additional "free" electrodes can be placed where desired. An optional small chamber, formed from a disposable plastic culture dish and Gootch rubber tubing, provides for "barrier" recording within the larger chamber. Interpretations are given of the electrical responses of nerve and muscle in terms of longitudinal currents along the preparation within the suction electrode tubes.

Do So

The SARS-CoV-2 pandemic has demonstrated both positive and negative effects on the environment. Major concerns over personal hygiene, mandated and ease in lockdown actions and slackening of some policy measures have led to a massive surge in the use of disposable personal protective equipment (PPE) and other single-use plastic items. This generated an enormous amount of plastic waste from both healthcare and household units, and will continue to do so for the foreseeable future. Apart from the healthcare workers, the general public have become accustomed to using PPE. These habits are threatening the land and marine environment with immense loads of plastic waste, due to improper disposal practices across the world, especially in developing nations. Contaminated PPE has already made its way to the oceans which will inevitably produce plastic particles alongside other pathogen-driven diseases. This study provided an estimation-based approach in quantifying the amount of contaminated plastic waste that can be expected daily from the massive usage of PPE (e.g. facemasks) because of the countrywide mandated regulations on PPE usage. The situation of Bangladesh has been analysed and projections revealed that a total of 3.4 billion pieces of single-use facemask, hand sanitizer bottles, hand gloves and disposable polyethylene bags will be produced monthly, which will give rise to 472.30 t of disposable plastic waste per day. The equations provided for the quantification of waste from used single-use plastic and PPE can be used for other countries for rough estimations. Then, the discussed recommendations will help concerned authorities and policy makers to design effective response plans. Sustainable plastic waste management for the current and post-pandemic period can be imagined and acted upon.

The Banuchi graft dispenser is an instrument for transplanting a plurality of hair grafts into preformed holes that facilitates and reduces the time of the implant procedure. The graft dispenser is an elongated hollow tube having both proximal and distal ends open to facilitate the hair graft loading process. It has an open channel extending along the length of the tube that holds the grafts, simplifying the counting process during the procedure. This instrument offers many advantages. The most attractive advantage for both patients and surgeons is that it reduces the time of implantation significantly. This reduction in time is due to the fact that with the graft dispenser, the surgeon can use the instrument not only to hold the grafts, but to dilate the preformed incisions and make the insertion more accurately and quickly. The new instrument has been designed in stainless steel and soon will be available in disposable plastic for further convenience. A multiple-channel instrument with a common funnel has been tested and proven to be very useful. A special tray to keep the loaded grafts in saline solution has also been designed.

Syringes, blood container pots and test tubes have been investigated to determine whether they act as sources of contaminants during trace element analyses. Urine containers were investigated to decide which materials do not absorb mercury from dilute solutions. No copper and little magnesium contamination was found. Zinc contamination was unpredictable. Very large amounts of zinc leached from the rubber end cap of the piston of disposable, plastic sterile syringes. The B.S.I. Standards for disposable syringes were shown to be unacceptable for heavy metals.

The application of AMS to the detection of 14C makes possible a new class of sensitive experiments in molecular biology. Such experiments inherently produce large numbers of samples for the determination of biological variability in molecular interactions. The samples vary in 14C concentration over many orders of magnitude. We added TiH2 to aid the reduction of CO2 by zinc in a sealed tube to reproducibly make graphite without sample cross-contamination. The CO2 is transferred from a combustion tube to the reaction tube through a disposable plastic manifold. The sealed tubes are heated to a single-reaction temperature in a muffle furnace. The process is complete within 5 h. Bulk isotopic fractionation in the finished graphite is less than 0.5%.
