Common pleuro-pulmonary complications of uremic patients under hemodialysis

The current study was conducted in hemodialysis unit - Minufiya University Hospital to detect common pleuro-pulmonary complications in uremic patients under regular hemodialysis. This study included 20 patients [8 males, 12 females] with mean age of [44.6 -/+ 13.78] years on regular thrice weekly hemodialysis for a period 6 months .We excluded from the study smokers,other diseases that affect chest, non compliant patients during the period of study and patients who received recombinant human erythropoietin. All patients were subjected to full history taking, full clinical examination, renal function tests, complet blood picture, arterial blood gases analysis, radialogical study of chest and heart, spirometric study. In this study about 55% of the patients showed pulmonary complications in the form of bronchopneumonia, acute bronchitis, lobar pneumonia, pleural effusion, tuberculosis and pulmonary oedema. The caustive organisms in these cases of pulmonary infection were Staphylococcus aureus, Streptococcus viridans haemophillus, pneumococci and tuberculous bacilli. Pleural effusion was transudative in nature. The PaO[2] was significantly decrease after 1 hour from begining of hemodialysis. This was due to hypoventilation caused by decrease CO[2] due to its loss in dialysis fluid, alkalosis and use of bioincompatable membranes. As regards spirometric measures, there was no significant improvement of VC, FVC, FEV[1] /FVC, MMV where as improvement in FEF [25-75%] was significant: This is due to removal of interstial, peribronchial fluid by hemodialysis with removal of toxins that impair distensibility and causes reversible spasm to smaller airways. Also there was signifcant fall in PEFR one hour after the start of hemodialysis. This is correlated with occurence of hypoxaemia and broncho-constriction which occur at that time, although there was significant improvement of PEFR after hemodialysis but not correlated to normal values. Recommendations include use of non complement activating membrane and a dialysis system in which loss of carbon dioxide can be prevented, measuring spirometric variables before and after dialysis and close observation both clinically and radiologically, for these patients

Thin layer chromatography of some coloring matters in food and pharmaceutical preparations

Thin layer chromatographic methods were described for the identification of even permitted coloring matters used in food and pharmaceutical preparations in Egypt. Two dimensional thin layer chromatography technique was tried in the present work to get better separation of the tested food dyes. The best separation when using the two dimensional technique was obtained on microcrystalline cellulose. Spectrophotometric determination of the chromatographically separated dyes was done with sufficient accuracy as proved by spiking technique

Detection of arrhythmia by auto-correlation method

This paper discusses the possibility of ceasing the auto-correlation analysis methods to study the different types of arythnia in electrocardiogram. Seven case studies have also been given and the obtained results are presented to provide a demonstration and verification of the technique

value of the laparoscope in the diagnosis of polycystic ovary

In this paper we studied 171 patients with polycystic ovarian disease diagnosed by laparoscopy. The disturbances of the menstrual cycles varied between amenorrhoes, secondary or primary, oligohypomenorrhoea, menorrhagia or regular cycles. In performing laparoscopy 160 patients had general anesthesia and 11 patients had local anesthesia. Laparoscoy revealed that the polycystic changes of the ovaries were not always bilateral, but were sometimes unilateral. There were 141 patients with bilateral changes and 30 patients with unilateral changes in the left ovary. All the ovaries, however, showed a smooth, pearly, white thick surface with the loss of the surface indentations of the normal ovary
