Comparison Between Incremental and Single-Dose Allergen Administration in Bronchial Provocation Tests

To study the effect of different schedules of allergen administration on the early (EAR) and late allergic reaction (LAR), 15 asthmatic patients with dual response after allergen challenge were submitted to two consecutive bronchoprovocation tests (BPT). BPT₁ was carried out with semilogarithmic increase of allergen doses until a FEV₁ drop of 20% was recorded. BPT₂ was performed 2 weeks later using the highest allergen dose that had elicited the dual reaction in BPT₁. Both EAR and LAR were very similar for a given patient. As the allergen dose used in BPT₂ is smaller than the cumulative allergen dose administered in BPT₁, this protocol takes into account a possible influence on BPT₂ of bronchial hyperreactivity induced by BPT₁ performed 2 weeks before.     

Laparoscopic hysterectomy

Summary Thirty-three patients were selected for laparoscopic hysterectomy and operated on in the Department of Obstetrics, Gynecology and Reproductive Medicine of Clermont-Ferrand University Hospital. Surgical techniques included blunt dissection with scissors and bipolar coagulation to achieve hemostasis. A case was considered successful when all the uterine vessels were treated by laparoscopy. Twenty-four cases were completed laparoscopically (72.7%). None of these patients had postoperative bleeding; 22 had an uneventful postoperative recovery. Nine procedures were converted to laparotomy (27.3%), five because of a difficult or unsatisfactory hemostasis. We conclude that in selected cases, a total hysterectomy can be performed safely by experienced laparoscopists. Further technological progress is necessary to make this procedure more acceptable. Its value as compared to the others will have to be demonstrated.     

Ipsilateral cluster headache and chronic paroxysmal hemicrania: two case reports

We report two patients with ipsilateral attacks of cluster headache and chronic paroxysmal hemicrania. The first patient, a 33-year-old man, started having attacks of chronic cluster headache at the age of 27. At 33, they were replaced by typical attacks of ipsilateral chronic paroxysmal hemicrania which showed a dramatic improvement with indomethacin 150 mg daily. After two days of complete remission, cluster headache attacks reappeared and persisted until verapamil, 360 mg a day, was added to indomethacin. The second patient, a 45-year-old man, first developed attacks of episodic cluster headache at the age of 35. At 44, he experienced ipsilateral typical attacks of chronic paroxysmal hemicrania, and two months later attacks of cluster headache. Under verapamil 240 mg daily, attacks of cluster headache disappeared, but those of chronic paroxysmal hemicrania increased in frequency until indomethacin 150 mg daily was added. These observations suggest a close relationship but not a similarity between cluster headache and chronic paraoxysmal hemicrania, and show the practical therapeutic interest of maintaining this distinction.     

Training of interviewers in the utilization of standardized questionnaires in psychiatry: studies realized with the Present State Examination (PSE)]

Interview questionnaires offer more validity than self-administered format in exploring psychopathological or psychosocial phenomena of interest in psychiatric research. If used, special care needs to be paid to interviewers' training and ensuring that they maintain their reliability. No widespread training standards exist and each schedule may carry its own procedure. Our aims are to indicate how we trained interviewers with the French version of the Present State Examination (Wing, Cooper and Sartorius, 1974) and how we checked and kept acceptable interraters reliability during one study. We will provide data on the interraters reliability during the training and the study, as well as the test-retest reliability. These results will be used to support some guidelines when using this sort of psychiatric research questionnaires in order to ensure comparability both within the study and between studies.     

Local fibrinolysis for superior mesenteric artery thromboembolism

A 66-year-old man with atrial fibrillation was referred soon after developing left lower limb and abdominal pain with rectal bleeding. An immediate flush aortogram showed embolic occlusion of the left distal superficial femoral artery and superior mesenteric artery (SMA), 3 cm from its ostium. Recombinant tissue plasminogen activitor (rtPA) 40 mg was selectively in stilled in the SMA in two boluses. Abdominal symptoms resolved within 48 h, and complete recanalization of the SMA was shown on angiography. Exploratory laparotomy after 72 h showed a normal small bowel and right colon, and was completed by femoropopliteal embolectomy. Six months later, the patient remained asymptomatic.
