Complete migration of retained surgical sponge into ileum without sign of open intestinal wall.

A 24-year-old woman came to the emergency room with a history of diffuse abdominal pain in the form of colic, nausea, vomiting and intestinal constipation. Clinical and ultrasound findings suggested intestinal obstruction due to foreign body. She had been submitted to a cesarean section 4 months previously at another hospital. At laparotomy, a ileum loop was found to be distended by an inside large and hardened mass with another intestinal loops and omentum density adherent. An ileotomy was performed on the compromised segment with terminating anastomosis. When opened surgical specimen it was observed an intraluminal surgical sponge that had completely migrated into the interior of the ileum and stopped next to ileumcecal valve. No fistulas or open intestinal wall were observed.

Self-administered pain-relieving manoeuvres in primary headaches.

We investigated the use of self-administered pain-relieving manoeuvres on a sample of 400 patients with primary headaches--represented by an even distribution of migraine without aura (MO), migraine with aura (MA), episodic tension-type headache (TH), and cluster headache (CH)--consecutively seen at Padua and Parma Headache Centres. Manoeuvres on various regions of the head were used by 258 patients (65% of the cases). The most applied procedures were: compression (114 out of 382 manoeuvres; 30%), application of cold (27%), massage (25%) and application of heat (8%). A significant (P < 0.001) relationship was found between headache diagnoses and type of manoeuvre. In MO patients the application of cold (38% of the manoeuvres) and compression (36%), used mainly on the forehead and temples, prevailed; compression, mainly on the temples, was the most frequent procedure (44%) in MA patients. Massage on the temples and nape was the predominant manoeuvre (43%) in TH patients, whereas in the CH group, which more often required heterogeneous procedures, none of the above-mentioned manoeuvres was prevalent. Compression, as a diagnostic criterion for MO, had a sensitivity of 33% and a specificity of 86%; for the application of cold the figures were 36% and 84%, respectively. Massage had a sensitivity of 33% and a specificity of 80% for TH. The efficacy of the self-administered manoeuvres in reducing pain was scarce. Only 8% of the manoeuvres, in fact, resulted in a good or excellent pain control. Moreover, the efficacy of the manoeuvre was often momentary, wearing off when the manoeuvre stopped. In spite of this, 46% of the subjects used the manoeuvres constantly, at each attack.

Our experience in the diagnosis of intraocular tumours by a B-scan computerized system and angiodynography (Doppler). Preliminary results.

The authors compare the ultrasound diagnostic results of intraocular tumours by A/B-scans (Sonomed B 3000, Sonocare, Sonovision STT-100) with images obtained using computerized B-scan (Sonocare, Sonovision STT-100, Acoustic Tissue Typing ATT) and angiodynopgraphy systems (Quantum Philips). The Sonovision uses a computerized ultrasound spectrum analysis to assess the probability that a given lesion is a certain tumour, rather than another. The ATT system provides diagnostic probability for type B and type E melanoma, for haemangioma and metastatic carcinoma. The Quantum ultrasound equipment was developed for studying the heart and the major blood vessels. It is a colour Doppler that simplifies the Doppler technique, allowing it to study small anatomical parts such as tumour-like lesions of the eye. The Doppler technique ascertains the presence and the velocity of blood flow in the tumours. In presenting the preliminary results with the new techniques the authors are aware that the ATT system is not designed for some of the lesions under study (melanomas after conservative radiotherapy).

Echography of optic disc related pathology in diabetic retinopathy.

Combined A- and B-scan examination of eyes with diabetic retinopathy and opaque media provides information about the presence and density of vitreous hemorrhages, can detect membranes inserting into the optic disc or the retina and differentiate them from retinal detachment. Absolute and relative indications for echographic examination are listed and some echograms concerning vitreous hemorrhage, proliferating membranes and traction retinal detachment are presented. The value of both A-scan standardized echography and contact B-scan technique for previtrectomy evaluation is stressed.

Disposable film cover for the tip of Goldmann's tonometer.

The application of a thin, transparent, polyvinylchloride film on the double prism of Goldmann's tonometer is proposed, so as to prevent bacterial and viral infection during tonometry. This film, mounted in such a way as to facilitate its application, is supplied in disposable sterile packaging. The use of the film does not alter the calibration of the instrument and does not substantially modify readings thereby obtained.
