Thermal performance of internal and external wall insulation in existing buildings in the south of Algeria

The development of a computer program based on the implicit finite difference method is presented in this paper to determine the thermal performance of internal and external wall insulation in existing buildings. Temperatures are calculated under the climatic data of the Adrar region. This climate is characterized by very high temperatures in summer, exceeding 45[degree]C, and an intense solar radiation with a maximum of 1000 W/m[2]. Measured on horizontal surfaces, the amount of solar radiation is evaluated using the Capderou numerical model. According to the simulation findings, the thermal performance of external wall insulation is the same in the two cases, the choice thus becoming restricted to technical and economic reasons.

[Liver involvement in Gaucher's disease: a tunisian cohort study]

Gaucher disease is a sphingolipidosis related to glucocerebroside storage in reticuloendothelial cells leading to multisystemic disease. Liver involvement is frequent but clinical expression is rare. The aim of this study is to evaluate liver involvement among a cohort of 45 patients with type 1 Gaucher disease. Hepatomegaly often mild to moderate was seen in 86 per cent of cases. A correlation was noted between hepatic involvement, spleen enlargement and severity index score. Portal hypertension was documented in 20 per cent of cases and seemed to be primitive. Four children had cirrhosis and two a hepatopulmonary syndrome. Splenectomised patient didn't show worsening of liver involvement. Liver complications were more frequent in pediatric patients comparatively to adult patients in this cohort

[Testicular plasmocytoma: a case report]

Extramedullary plasmocytoma is rare, with less than 50 reported cases and only 8 cases of primary testicular plasmocytoma. Report of a new case. This report concerns a 65 years old patient presenting an enlargement of the testis. The diagnosis of testicular plasmocytoma was made on histological examination. There was no evidence of bone marrow involvement or systemic signs of myeloma. This case will be studied with a review of the literature

[Testicular lymphoma: report of 4 cases]

Background: Primary testicular lymphoma is the most common testicular malignancy in the elderly, account for 1% of all non Hodgkin lymphoma [NHL]

The aim was to report from new cases of testicular lymphoma

Cases: We report the only four cases of testicular lymphoma observed in a period of 15 years; all these cases were primary diffuse large cell B NHL. Disease course is usually aggressive, with widespread organ involvement. Retrospective analyses show a poor prognosis for this presentation

propos d'un cas de cortico-surrenalome chez l'enfant

The authors present. the case of a two year old boy with a virilization syndrom and hypercortisolism and in whom an abdominal mass oriented the diagnosis toward a cortical adenoma. This was confirmed by x rays and surgery Some criteria of malignancy will be looked for so chemotherapy can be started, This therapy is reviewed by the authors
