[Oculopharyngeal myopathies: value of myotomy of the superior sphincter of the esophagus. Apropos of a case].

Since 3 years, a 74 year-old man suffered of swallowing impairment, weight loss, bilateral ptosis and proximal muscular weakness. Electron microscopy disclosed intranuclear tubular filaments and confirmed the diagnosis of oculopharyngeal muscular dystrophy. Upper oesophageal sphincter myotomy was performed with complete improvement. Four months after surgery, swallowing disorders were not recurrent and weight gain was substantial.

[Leiomyosarcoma of inferior vena cava. A new case. Surgical management (author's transl)].

The authors report on a new case of leiomyosarcoma of the inferior vena cava, to add to the sixty five cases already mentioned in the literature. The patient had been suffering from subcostal pains for 12 years, and an adenomyoma of the gall bladder was diagnosed. The tumor was discovered in the course of a cholecystectomy. The vena cava was resected and ligated below the renal veins. After describing the case, the authors go on to review the literature and stress the fact that the prognosis, which is often severe, could be improved by earlier diagnosis.

[21-hydroxylase deficit revealed by hyperkalemia in the absence of renal failure in an insulin-dependent diabetic (author's transl)].

The authors report a case of severe hyperkalemia (7 mmol/l) in an insulin-dependent diabetic in the absence of renal failure. This hyperkalemia was due to hypoaldosteronism caused by inadequate hormone biosynthesis in the absence of 21-hydroxylase. Replacement therapy allowed normalization of clinical and laboratory parameters. The various causes of hyperkalemia in the absence of renal failure in insulin-dependent diabetes are discussed, notably the renin deficiency hypoaldosteronism syndrome. This case study is remarkable for a number of reasons, including the very limited degree of virilization, the occurrence of a pregnancy, and the degree of salt excretion. This is a new observation in the diabetic, and is apparently a coincidental association since deficits in 21-hydroxylase are not usually associated with insulin-dependent diabetes.

[Leiomyosarcoma of the inferior vena cava (author's transl)].

A further case of leiomyosarcoma of the inferior vena cava is described, bringing the total number reported in the published literature to 63. The tumor was located in the inter-renal segment of the vena cava, and was effectively removed by excision combined with venous reconstruction, enabling conservation of the renal veins. These malignant tumors occur more frequently in women, and their symptomatology varies according to their location in either the upper, middle or lower area of the inferior vena cava. Upper segment tumors are revealed by a Budd-Chiari syndrome or obstruction of the right atrium and are usually rapidly fatal. Middle and lower segment tumors can be treated surgically, if diagnosis is made early enough and cavography is conducted.
