[Malignant fibrous histiocytoma of the femur after total hip prosthesis. Apropos of a case].

The development of a pathological fracture of the lower third of the femur in which a total hip arthroplasty had been cemented 20 months earlier, was followed several months later by extensive osteolysis round the prosthesis. After much discussion, a diagnosis of malignant fibrous histiocytoma was made. A review of the literature revealed a similar case and confirmed the possibility of induction of this rare tumour in one of several ways. Whilst the oncogenic effect of an implant cannot be proved, it cannot be excluded.

[The course of a case of Maffucci's syndrome].

The syndrome of Maffucci is characterized by angioma association of the enchondromatose. It is a relatively rare syndrome. The lesions are evolutived. The treatment is surgical. His pronostic is marqued by high percentage of malign degenerescence.

Painful subungual keratotic tumors in incontinentia pigmenti.

We report a case of dyskeratotic subungual tumor in a 28-year-old woman. The patient presented achromic lineal lesions, typical of residual incontinentia pigmenti (IP), on her legs. Furthermore, the physical examination showed anodontia of the right incisor tooth. The familial background demonstrated miscarriages of male fetuses and characteristic dental abnormalities of IP in female siblings. The patient's daughter presented a typical background of IP and dyschromic splashed lesions. Light and electron microscopic studies of the subungual tumors were made. The analogy between subungual tumors of IP and keratoacanthoma is emphasized.

[Childhood benign chronic bullous dermatosis. Differential diagnosis with dermatitis herpetiformis and bullous pemphigoid].

We review the literature on benign chronic bullous dermatosis of childhood and the criterions for its diagnosis and differentiation from dermatitis herpetiformis and bullous pemphigoid. The diagnosis among these conditions should be based on immunofluorescence data. BCBDC shows linear IgA on the basal membrane zone. Its course is benign and there is not enteropathy. In dermatitis herpetiformis we find granular IgA and complement in the tips of dermal papillae. It is a chronic illness and the patients have a gluten-sensitive enteropathy. The bullous pemphigoid is a severe condition which needs corticosteroids for its control. Direct immunofluorescent studies reveal IgG and complement in a linear pattern in the membrane basal zone. It is associated with circulating antibasement membrane zone IgG.

[84 fractures of the lower end of the tibia in adults. Attempt at a classification].

Eighty-four articular fractures of the lower end of the tibia were reviewed. One third were compound and three out of four were comminuted. Seventy-three cases were treated by internal fixation. The results were satisfactory in about half of the cases. In eight severe sepsis was found and had to be treated by arthrodesis. In 80 cases reviewed, a satisfactory reduction was obtained in only 52 cases. A classification into three types is proposed.

[Multiple clear-cell acanthoma].

Clear cell acanthoma is a benign tumor reported by Degos et al. in 1962. Most commonly the acanthoma presents as a solitary nodule on the lower limb in late middle-aged persons. We've found only 11 papers about multiple clear cell acanthoma. We describe a 73 years old patient who had 21 lesions, the highest number found in the literature.

[A review of 86 fractures of the lower end of the femur treated by internal fixation using A.O. blade-plates (author's transl)].

The authors have treated 86 fractures of the lower end of the femur by internal fixation with an A.O. blade-plate. An adequate follow up was made in 71 cases. A classification of the fractures is given. Half of the fractures were either complex or involved the joint. The technique that was used is described. The authors consider that an immediate cancellous autogenous bone graft is worthwhile. 8 cases of non-union, 7 stiff knees and 31 malunions were seen; 70 per cent of cases achieved satisfactory function.

The effect of pentoxifylline on red cell deformability in cerebrovascular accidents.

A study was carried out in 49 recent cerebrovascular accident (CVA) patients to compare red cell deformability in this group with that in 65 healthy controls. Deformability was determined using a standard technique for measuring blood filtration time through a micropore filter. Filtration time was shown to be significantly reduced in the CVA patients. All patients had ACTH treatment, 28 of them receiving in addition 600 mg pentoxifylline per day, either by intravenous infusion or by intramuscular injection. After 2-weeks' treatment, red cell deformability was increased in the patients treated with pentoxifylline and ACTH and was unchanged in the 21 patients receiving only ACTH (p less than 0.001). The authors discuss the role of increased red cell deformability in the clinical prognosis of the patients.

[Extensive osteolysis secondary to the implantation of thread in bone (author's transl)].

The authors have treated a severe strain of the knee in which the anterior cruciate ligament was reinserted using a Dacron thread driven through a tunnel in the upper end of the tibia. 7 years later a lytic bone lesion had to be grafted in which remnants of the Dacron were found. The role of low grade infection or intolerance to foreign material is discussed.

[Interest of prolonged peridural anaesthesia in the treatment of thoracic injuries (author's transl)].

Prolonged peridural analgesia relieves the pain and thanks to immediate return of ventilatory function avoids most complications of poor prognosis in mobile sternum. After a historical and pharmacological survey, the authors describe a standard technic, the course and the necessary supervision. The study of 29 cases of mobile sternum of variable gravity, treated in this way, permitted the authors to determine the indications and contra-indications and the role of associated treatments: physiotherapy, surgical fixation, respiratory assistance. The rare failures may benefit from another therapeutic method.
