[Emphysematous pyelonephritis: report of 3 cases].

Emphysematous pyelonephritis is a rare and life-endangering suppurative infection characterized by the production of gas in the renal parenchyma and perirenal space. It affects mainly patients with diabetes mellitus. Authors report three cases of emphysematous pyelonephritis and insist on the role of radiological investigations in diagnosis. Through an exceptional case of emphysematous pyelonephritis revealed by hematemesis, they remind the progression route of infection from retroperitoneal to mediastinal space. Prognosis of emphysematous pyelonephritis depends on the patient's general health status and rapidity of diagnosis and treatment. Percutaneous drainage is an alternative to major surgery and is particularly indicated in cases of single kidney or in an inoperable patient.

[Prognosis of retinoblastoma. Report of 50 cases].

PURPOSE: The aim of this study was to analyze the factors influencing the prognosis of retinoblastoma. MATERIALS AND METHODS: In 50 children with retinoblastoma, 69 eyes were reviewed. All patients had a full ophthalmic examination, a B-scan ultrasound, a computerized tomography scan and a pediatric examination. We performed enucleation in 47 eyes (with a histopathological study), external beam irradiation in 16 eyes, curitherapy in 4 eyes, cryotherapy in 3 eyes, and adjuvant chemotherapy in 7 cases. RESULTS: The global survival rate was 87.5%. The main aggravating factors were: the size of the tumor and the extraretinal involvement with extension within the chroid, the sclera, and the optic nerve. CONCLUSION: The prognosis of retinoblastoma mainly depends on the extraretinal invasion.

[Pulmonary emphysema: quantification using computed tomography and correlations with respiratory function tests].

Pulmonary emphysema can be defined in precise anatomical terms. Only histological examination of an entire lung will enable the extension and the severity of the emphysema to be fully assessed. The authors propose a visual score, using computed tomography to quantify emphysema in 61 subjects. 51 had chronic airflow obstruction (BPCO) and were divided into 31 chronic bronchitics (BC) and 20 emphysematous subjects (EP). 10 volunteers who were free of any respiratory pathology were chosen as controls. A visual score for the computed tomography was established for the subjects as a whole. Double reading of the data enabled the reproducibility of the method to be checked in 10 subjects (r = 0.98, p < 0.001). No emphysema was found in the 10 controls, the computed tomography score was appreciably more elevated in the EP subjects than in the BC group at 1.3 and 0.44 respectively (p < 0.001). In the BC, the computed tomographic score was not correlated with the PaO2 (r = 0.54, p < 0.001) and the FEV1 (VEMS) (r = < 0.44, p < 0.05). On the other hand, in the PE group, the score was correlated with the FEV1 (r = 0.52, p < 0.05) and the residual volume (r = 0.06, p < 0.05) and the total lung capacity (r = 0.63, p < 0.05) and the TLCO (r = 0.56, p < 0.05) and the TLCO/VA (r = 0.59, p < 0.05). The adoption of a visual computed tomographic score enabled the authors to find the correlations between pulmonary emphysema and the most specific tests of respiratory function.

[Hepatic puncture-biopsy with embolization of the tract].

Recently reported by Shuang, percutaneous liver biopsy with embolisation of the tract (PLBET), involves the use of a coaxial needle system permitting embolisation of the tract while avoiding the haemorrhage complications of conventional biopsy. We conceived a system similar to shuang's 14G, 16G. We report the description of this system and the results obtained on 50 patients. Thanks to it simplicity we believe that PLBET should definitely replace definitely the transjugular liver biopsy (TLB).

[Pulmonary complications after gastrografin inhalation during radiographic control of esophageal anastomosis].

Tracheal penetration of water soluble contrast media (gastrografin) for X-ray control, after gastro-oesophageal anastomosis, resulted in acute pulmonary oedema in two patients. In this type of surgery, mediastinal dissection was responsible for recurrent nerve injury. Inhalation was due to this recurrent nerve palsy. The pulmonary oedema could be related to gastrografin high osmolarity. Therefore, to prevent this complication, previous laryngeal cavity examination is recommended before carrying out the X-ray investigations. In case of recurrent nerve paralysis, barium sulphate or lipiodol should be preferred because of their lack of effect on the lungs.
