Regional ventilation-perfusion study with Xe133 in cases of idiopathic kyphoscoliosis

This work was carried on ten patients with idiopathic kyphoscoliosis. Complete pulmonary functions on all the patients as well as regional ventilation/perfusion studies on five of them using Xenon [133] were done. The ventilatory defect on the studied cases was essentially that of restrictive pattern. There was no evidence of airway obstruction since the forced expiratory volume in the first second [FEV[1]] and maximum expiratory flow rate [MEFR] were with in normal. All lung volumes were reduced except the residual volume which registered a normal value. There was CO[2] retension and hypoxemia attributable to alveolar hypoventilation and ventilation/perfusion [V/Q] imbalance. The latter error was illustrated by diminusion of ventilation and perfusion of the lower lung zones that was evident in the right lung possibly due to lung compression by the scoliotic curve. The disturbance in perfusion was less than that of ventilation with the result of low V/Q ratio at the lung bases and high V/Q ratio at the upper lung zones. That was partially responsible for arterial hypoxemia

Regional vetilation-perfusion study with Xe133 in patients with pectus excavatum deformity

Ten patients with pectus excavatum deformity have been evaluated by routine clinical, radiological, ECG and pulmonary function tests as well as radio-isotopic lung function studies using Xe[133]. The results showed no correlation between subjective complaints and objective findings and also no correlation with the degree of deformity. The routine pulmonary function tests showed a mild restrictive pattern. Arterial gas tensions showed a mild drop in PaO[2] and a normal PaCO[2] Regional lung study on five patients showed impairment of ventilation and perfusion in the form of hypoventilation and perfusion in the form of hypoventilation and hypoperfusion of Zone [3] of the left lung with corresponding hyperventilation and hyperperfusion of zone [3] of the right lung due to heart displacement to the left and compression of the left lung base

Role of the lung in patients with chronic renal failure under periodic hemodialysis

Fifteen patients with chronic renal failure were submitted to periodic hemodialysis by travenol hemodialyzer in the renal unit; Faculty of Medicine, Alexandria. Spirometric lung functions, blood gasometry and acid-base balance were evaluated before dialysis, immediately after dialysis and 24 hours later. The results alluded to the possibility of small-air way error in the essentially clear chest roentgenogram of these patients. However the ventilatory compensation of the lungs was still tremendous to keep the homeostatic balance within the acceptable range thriving for optimal performance

Evaluation of practical programmes on physical efficiency for girls in faculties of sports education

Assessment of the practical programmes on the physical performances and efficiency for girls in faculties of sports education has been carried out on 77 candidates taken as random sample. Pulmonary function tests, physical efficiency as well as athletic fitness tests were the sensitive variable scales for follow-up and evaluation of the practical programmes

Tuberculin test: a measure for clinical evaluation

Intradermal testing of tuberculin [intermediate strength] was performed on 100 subjects with different ages ranging from one to 65 years as a measure for clinical evaluation. Analysis of the results was done taking into consideration many factors as age, sex, physical conditions, clinical presentation, drug intake, treatment with anti-tuberculous therapy, time and chronicity of the disease. Also other factors and circumstances affecting the results of the tuberculin reaction were also assessed

study on the failure of first line antituberculous therapy in Egypt

The study was devoted to fifty patients with pulmonary tuberculosis who were treated and followed at Tanta Sonatorium Hospital. They received primary line anti-tuberculous chemotherapy [Streptomycin, isoniazid and para-aminosalicylic acid], in the usual recommended dosages according to the body weight. Failure of therapy in them was concluded after a suggested period of 6 months for which possible causes were suggested and studied
