[Efficacy of rituximab in lymphomatoid granulomatosis].

Introduction: Lymphomatoid Granulomatosis is a rare and serious disease, now considered to be a B-cell lymphoma, which is frequently associated with Epstein-Barr virus infection. There is no consensus on treatment, which is usually based on steroid therapy, either alone or combined with cyclophosphamide and combination chemotherapy.

Case Report: We report the case of an asymptomatic patient diagnosed after the incidental discovery of bilateral nodular opacities on their chest x-ray.

[Pulmonary malacoplakia caused by Rhodococcus equi in AIDS: a case report].

We describe the observation of a right upper lobe consolidation with cavitation produced by Rhodococcus equi in a patient suffering from AIDS. The inefficacy of a prolonged antimicrobial therapy adapted against R. equi led to a right upper lobectomy.

Esophageal perforation during attempted endotracheal intubation.

Perforation of the cervical esophagus in the course of attempted intubation of the trachea is a very rare accident, or at least rarely reported. Over the past 11 years, 12 patients ranging in age from 44 to 72 years were treated in our unit. If suspected, esophageal perforation is easy to diagnose when intubation has been difficult or when the patient complains of dysphagia and neck pain.

[Right pneumonectomy for carcinoma with resection of the carena and left tracheo-bronchial anastomosis: 3 cases (author's transl)].

Extended pneumonectomy for carcinoma is associated with very poor results. However, a tumour which remains limited to the bronchial tree does not perhaps have such a poor prognosis as those which involve neighbouring organs. Valuable survival periods may be obtained after right pneumonectomy with resection of the carena.

[Acute hyperparathyroidism, diagnosis and treatment. 10 recent cases].

The authors report 10 observations of acute hyperparathyroïdism crisis cases operated without death. They draw their conclusions from their own experience and from published cases. The evolution on the medical treatment is invariably mortal.

[Early surgical management of severe corrosive burns of the oesophagus (author's transl)].

The authors have treated, as an emergency, 120 adults with corrosive burns. Thet were 22 patients among them checked as severe burns, i. e.

[Caustic burns of the oesophagus in the adult. Histopathological study of 12 cases (author's transl)].

A histopathological study of 12 cases of major caustic burns of the oesophagus serves as a basis for a description of the lesions and to demonstrate the inexorable progression to fibrosis. The lesions are most frequantly diffuse, regardless of the substance responsible. Four morphological stages may be distinguished, superimposed on the clinical picture.

[Tuberculosis and caustic eso-gastric burns. Critical reflections on one case].

The diagnostic problems which may be raised during caustic oesophago-gastric burns and concommittent tuberculosis, of which the symptoms may be masked by the richness of the initial clinical picture are discussed here. The authors emphasise the necessity of prophylactic anti-tuberculous treatment, before any surgery when there is any suggestion of tuberculosis even siabilised.

[Perforations of the cervical esophagus in attempted tracheal intubation. A report of 12 cases].

The authors underline the factors favouring perforation of the oesophagus during intubation in the light of 12 personal cases: difficulty in intubation, use of an introducer, inexperienced operator. Such a perforation may result in mediastinitis and should be treated early with massive polyvalent antibiotics and a surgical suture left at rest for approximately one week.

[Profile of surgical tumors of the mediatinum. Apropos of a series of 742 operated patients].

The authors seek to draw statistical conclusions on the basis of 742 surgically treated mediastinal tumours. Tumours of the thymus were the most common (20%). They were followed by tumours of the thyroid, neurogenic tumours, haematosarcomas and mediastinal cysts - all with an occurrence rate of around 12 to 15%.

[Large esophagogastric caustic burns in the adult].

The authors treated, as an emergency, severe caustic burns in adults. They present 13 cases and discuss four deaths. Critical analysis of these observations,compared with the findings of pathology and in the literature, permit one to consider the therapeutic indications.

[Surgical treatment of pulmonary metastases from rectocolic cancers. Apropos of 21 cases].

The authors report 21 cases of pulmonary metastases from operated cases of rectal and colonic carcinoma. Half the patients were aged between 60 and 70 years. In all cases except one the primary tumour was known and treated surgically before the metastasis occurred.

[Cecal perforations in the course of acute idiopathic distension of the colon].

On the basis of two fatal cases of perforation of the caecum secondary to dilatation of the colon without obstruction, the authors discuss the measures which should be instituted in the presence of this condition. These consist, preventively, of decompression of the colon by caecostomy if the diameter of the caecum reaches 10 cm and, curatively, a right hemi-colectomy, not associated with immediate re-establishment of the continuity of the digestive tract.

[71 pulmonary hamarto-chondromas].

Seventy-one hamarto-chondromas were operated on at the Centre Chirurgical Marie-Lannelongue from January the 1st 1958 to September the 1st 1975. Pulmonary hamarto-chondroma is always a slowly evolving benign tumour, usually found in patients between 40 and 60, and twice as frequent in males as in females. There are two different kinds.

[Technic of pleural drainage (emergency pleural drainage)].

Pleural effusion is still often poorly drained: - incorrect introduction of the drain into the thorax, - ill-chosen position of the drain. Simple drainage, a minima, is considered here, that which requires no broad surgical incision and which, in cases of effusion with compression of the lung, is often a life saving procedure which any doctor should be able to carry out, especially if he deals with emergencies. The surest technique consists of placing a No.

[Benign esophagotracheobronchial fistulas in adults].

Oeso-tracheal-bronchial fistulas are rare in adults and their precise etiology is often difficult to determine, apart from the traumatic causes. Their diagnosis, based on symptoms, is confirmed by tracheal, bronchial and esophageal endoscopy, esophageal opacification and esophageal cineradiography. Treatment should permit one to avoid progressive pulmonary deterioration.
