Retained foreign needle in the thoracic spinal canal in a child: Case report

Background: The presence of retained foreign bodies in the spinal canal has been reported in the literature. They are attributed to retained pieces of medical equipment after surgery, or, following trauma, to residual bullets, glass fragments, or knife blades. Although some retained materials do not cause any neurological deficits in the short run, others may become symptomatic months later. Case Description: A 2-year-old male presented with a history of intermittent fever and mild lower extremity weakness. Notably, the original infectious workup was negative. However, a noncontrast CT scan later documented a needle-shaped foreign body in the spinal canal at the T10 level. During the T10 laminectomy, a needle (i.e. from a medical syringe) was removed, the patient remained neurologically intact. The foreign body turned out to be a medical syringe needle tip. Conclusion: A 2-year-old male presented with fevers and mild lower extremity weakness attributed to an intraspinal needle tip found utilizing CT at the T10 level. T10 laminectomy allowed for removal of a small needle tip. This shows the importance of removing retained spinal foreign bodies to avoid further/future neurological injury, and/or the potential risks/complications of foreign body migration/sequestration.

Assessment of Growth Hormone , Insulin and Vit.D2 Levels for Children Suffering from Hypoweight in Kirkuk City

This study was done in the Pediatric General Hospital and Al-azadi Educational Hospital , the period from September 2017 to February 2018, aimed to evaluate levels of Growth hormone (GH), Insulin and Vit.D3 levels for children suffering from hypoweight aged (1-5)years, include 40 child, in addition to 20 healthy child. A medical syringe was used for collecting blood samples, drawing (5)ml of venues blood from them and put it in test tube free from any coagulation material, it was put in centrifuge (3000rpm, 15min) for purpose obtaining blood serum then serum are separate and drawn by micropipette put it in a test tube used for (Growth Hormone, Insulin and Vit.D) tests. After test complete, the results of study showed a significant decrease (p≤ 0.01) in GH, Insulin and Vit.D2 levels. http://dx.doi.org/10.25130/tjps.24.2019.065

A Simple Homemade Electrospinning for Nanoscale Fibres Production

A high technology often is required by electrospinning device to produce a nanoscale fibre. This requirement results in difficulties to get the device simple design and operate with reasonable price. This paper presents the work to implement design of the electrospinning system. This electrospinning system consists of a main construction body, an electrical power supply to provide a voltage source direct current form, a syringe pump and a flat collector. The main body are made of acrylic with knockdown construction since acrylic is an easy material to shape. The power supply has a simple main single switch with high ferite transformer to produce high dc voltage through a diode – capacitor filtering. A used medical syringe has been modified as an injection pump to spray the materials into fibre form. A simple flat metal has been reconstructed to be electrode – ground collector to receive fibre product. The test was carried out using polyaniline materials. The general parameters in the production process are resolution of the spraying rate µℓ / minute and the power supply provide electricity in kiloVolt. The result of fibre production observed by using SEM shows that the electrospinning device successfully produces fibres on a nanometer scale.

Simulation of the medical syringe injection moulding process

This paper contains a description of tests including the simulation of the injection moulding of thin-walled products. The simulation was designed to analyse the potential impact of processing conditions and cooling conditions on the defects of thin-walled products of the body of the syringe. In order to obtain the correct results, the analysis was based on a simulation comparison with the data obtained after the injection mouldings were produced. Four cases were considered - parameters with reduced injection pressure and absence of pressure push, with a reduced temperature of the injection mould. The test results were analysed in conditions compliant with the recommendations of the production card and with the parameters optimised by computational algorithms of the computer programme. Simulations were carried out using the Simcon CadMould 3D-F programme. The paper describes the construction of a thin-walled body, which is the main segment of a medical instrument - a medical syringe. Also described in the paper are the process of injection of polymer materials and the characteristics of the production of medical syringes. In addition the computer programme software for the simulation of production processes was presented.

Synergistic effects of kaolin and talc in a bromobutyl rubber compound for syringe plunger application

The effectiveness of separate and combined incorporation of two natural, inexpensive, and nontoxic filler materials, kaolin and talc, at their various proportions in a bromobutyl rubber (BIIR) compound for a medical syringe plunger was investigated. The dispersion of kaolin was finer and more homogeneous than talc in BIIR. The curing was also enhanced in the presence of kaolin than talc. The difference in dispersion as well as reinforcing effects of the different fillers were reflected in the dynamic mechanical properties of the compounds. Tensile properties of the compounds were not significantly varied with varying kaolin/talc ratio of the compounds, however, tear strength decreased for higher contents of talc in the compounds. A significant synergistic reduction of compression set was achieved for 75/15 ratio of kaolin and talc in the rubber compound, very important for a plunger compound.
