[Treatment of an asthmatic crisis by acupuncture. Probable role in the onset of pneumothorax with development to status asthmaticus].

The onset of pneumothorax during acupuncture treatment has been reported since 1973. Usually unilateral, it occurs in patients free from any bronchopulmonary disease, and its consequences are therefore relatively benign. However, rare cases of bilateral pneumothorax have been reported since 1978, as well as a pneumothorax developing in asthmatic patients, with often dramatic consequences. A 15-year-old girl with a severe attack of asthma was treated by implantation of needles, and this coincided with the onset of a pneumothorax, and a subsequent state of status asthmaticus. A fatal outcome was only just avoided. The question is raised as to the technical quality of the implantations practised, as well as the validity and dangers of acupuncture in asthmatics, particularly during the acute attack.

[Acquired immunodeficiency syndrome in 4 homosexuals].

Two young homosexual men apparently without any obvious cause of immunosuppression suddenly developed a series of opportunistic infections. Two others presented with prolonged fever and multiple lymph node enlargement of obscure origin. Immunological investigations in these 4 patients showed skin anergy and inversion of helper/suppressor lymphocyte ratio. Proliferative responses to mitogenic agents, soluble antigens and allogenic cells were altered only in the 2 patients with opportunistic infections. Humoral immunity seemed to be preserved in all cases. These 4 patients had previously suffered from many sexually-transmitted infections, had spent some time in the United States and had signs of past or present cytomegalovirus infection. As in the U.S.A., where this "acquired immunodeficiency syndrome" suddenly developed during the past 2 years, one may suspect, among several hypotheses, that it is caused by a transmissible agent now present in France.

[Emergency treatment of severe hemoptysis by embolization of systemic arteries].

Over a 6-year period 23 patients with massive haemoptysis were treated at the Hôpital Tenon, Paris. Eighteen of these, usually considered "non-surgical" cases, underwent emergency embolization of the bronchial artery (B.A.E.). The immediate outcome was favourable in 14 patients; 4 died of early recurrence. B.A.E. therefore appears to be a valuable treatment of massive haemoptysis in "non-surgical" patients or in patients awaiting transfer to a thoracic surgery unit. However, because of the failure rate, B.A.E. cannot compete with thoracic surgery in its classical indications, and its effectiveness and safety should be compared with those of balloon catheter endobronchial tamponade in "non-surgical" patients.

[Acute respiratory failure disclosing bilateral diaphragmatic paralysis].

In the case of three patients an acute respiratory failure with alveolar hypoventilation is related to bilateral diaphragmatic paralysis apparently isolated from any other neurologic abnormalities. The current initial diagnosis of pulmonary embolism leading to admission in an intensive respiratory care unit, because of the severity of the acute respiratory failure, has to be rectified then. Bilateral diaphragmatic paralysis is suspected on account of the absence of any patent etiology, on increasing dyspnea in supine position and paradoxic movements of the upper abdomen (whether spontaneously or in attempted weaning of ventilation support). Bilateral diaphragmatic paralysis is asserted by electromyogram with measurement of nerve conduction velocities of the two phrenic nerves. In the first case, it appears early in the course of an amyotrophic lateral sclerosis; in the second case, it occurs before the presence of a herpes-zoster becomes patent. In the third case, paralysis seems to be idiopathic. Evolution is promising in the last two cases, owing to the reversibility of the lesions. The difficulty of diagnosis, the varying nature of etiology and prognosis encountered in these three cases are also apparent in the 15 cases published in medical literature. The small number of cases published up to now, contrasting with the cases we have witnessed over the last 3 years, leads us to think that this disease must exist more often and may remain unknown to us.

[Pulmonary emphysema, hepatic lesions, and insulin-dependent diabetes in a patient with alpha-1-antitrypsin (Pi ZZ) deficiency (author's transl)].

A 47-year-old patient with panlobular emphysema and insulin-dependent diabetes had an alpha-1-antitrypsin phenotype Pi ZZ deficiency. Liver function tests were abnormal, and postmortem examination of the liver demonstrated abnormal intrahepatocytic globules of A1AT (a typical finding when the allele Z is present), but also fibrosis with steatosis. The patient's sister, Pi ZZ, had neither diabetes nor bronchopneumopathy, and no anomalies in liver function. Needle puncture biopsy of the liver had not been conducted. The phenotype Pi ZZ is typically associated with panlobular emphysema in adults, and cholestatic hepatitis in children. From reports in the published literature, it appears that isolated hepatic lesions or those associated with emphysema are rare. The fortuitous association of diabetes and hepatic lesions in this typical case of pulmonary affection in an adult is discussed.

[Partial anomalous pulmonary venous drainage of the left lung into the innominate vein (author's transl)].

From 5 cases of partial anomalous pulmonary venous drainage of the left lung into the innominate vein, it has been thought of interest to situate this type of venous anomaly among the partial anomalous pulmonary venous drainage classification. It is revealed in 2 different ways. In adults, this malformation sets the problem of the diagnosis of an abnormal chest Xray, without symptom. In children, this vascular abnormality is discovered during the exploration of a congenital cardiopathy which causes the main symptoms. Embryological data are reviewed and statistics of frequency which lead to show that this type of partial anomalous venous drainage is often misunderstood, particularly with regard to anomalous venous drainage of the right lung.

[Severe pneumococcal infections of adults. 100 cases collected in three years (Claude Bernard Hospital, Paris) (author's transl)].

After retrospective in intensive care unit of 100 severe cases of pneumococcal infection in three years, the authors analyse the circumstances of onset (occurring in autumn of winter), the general status (without evident high risk population), the symptomatology (84% of meningitis, 30% of pneumonia), the origin of infection (essentialy otitis media in meningitis). The case fatality rate is 39%. Frequency of multiple visceral localisations and of bacteremias is emphasized.

[Cutaneous, subcutaneous, and lymph node cryptoccosis in a patient with sarcoidosis (author's transl)].

An Algerien patient aged 31 years with a histologically confirmed mediastinopulmonary sarcoidosis had a persistent stable miliary pulmonary x-ray image after cortisone therapy. Eighteen months after stopping the corticotherapy, he developed cryptococcosis which was mainly cutaneous, but associated with subcutaneous abscesses and peripheral adenopathy, and without lesions in the viscera or deep nodes. Cryptococcus antigens were present in the serum and there was a humoral and cellular immunity reaction towards the cryptococcus. Recovery occurred after amphotericin B and 5-fluorocytosine.

[Pleural effusions (chylous or nonchylous) with regional osteolysis: A case evocative of Gorham's disease].

In connection with one case of thoracic localized osteolysis associated to bilateral seral effusion, serohemorrhagic on the right, chylous on the left, the authors recall 13 similar observations. In this localization a pleural effusion is very frequent and specific to it, putting at stake the vital prognosis of the patient. These observations can be compared to multiple osteolyses and be grouped together under the name of "intraosseous capillary ectasies".

[Löfgren's syndrome, sarcoidosis and Bouillaud's disease].

The authors report two cases of Löfgren's syndrome, preceded by febrile polyarthritis with rise in antistreptolysin titer. The relationship between sarcoidosis and rheumatic fever is discussed. A review of the literature concerning Löfgren's syndrome with joint pain, permitted the authors to follow the course of present pathogenic concepts which haveled to the present opinion of the sarcoidosis nature of Löfgren's syndrome, when the latter is accompanied by erythema nodosum. The prolonged rise in antistreptolysin 0 titer which might suggest rheumatic fever, was not explained, but as the streptococcus was never found in throat swabs, it is probable that this was a non-specific phenomenon. However, certain authors believe that streptococcal infection, where it exists, may play a role, if not in the etiology of the sarcoidosis, at least in the Löfgren's syndrome which may lead to its discovery.

Anastomoses between the spermatic and visceral veins: a retrospective study of 500 consecutive patients.

BACKGROUND: Do visceral-spermatic vein shunts have any clinical impact on sclerotherapy of varicoceles? METHODS: The spermatic venograms of 500 consecutive patients were retrospectively reviewed to classify visceral-spermatic communications. Men with an average age of 27.8 years (range 11-65 years old) underwent sclerotherapy of a varicocele. Of the 500 men, 445 were referred for oligoasthenospermia (89%), 45 for pain (9%), and 10 for prevention of infertility (2%). After bilateral catheterization, percutaneous sclerosis was performed below the upper third of the sacroiliac joint. RESULTS: Three hundred forty patients (68%) had left-sided, 10 (2%) had right-sided, and 150 (30%) had bilateral varicoceles. Left side: Of 46 (9.4%) anastomoses, one (0.2%) communicated with the splenic vein and 45 (9.2%) with the inferior mesenteric vein of which 25 (5.1%) were a colic trunk with a competent valve, 15 (3.1%) were venules, and five (1%) were a single or double anastomosis. Right side: Of 48 (29.6%) anastomoses to the superior mesenteric vein, 34 (21%) were venules, 12 (7.4%) were a colic trunk with a competent valve, and two (1.2%) were a single or double vein. Our varicocele recurrence rate was only 1.2%. CONCLUSION: Visceral-spermatic vein communications are classified by number, morphology, and site. Percutaneous sclerotherapy could be optimized when performed caudally to these communications.
