Crohn's disease of the esophagus. A case report.

A case of Crohn's disease localized in the inferior third of the esophagus with negative radiological evidence, positive endoscopic evidence, and aspecific signs of esophageal wall inflammation is reported. Evaluation of clinical remission of dysphagia and endoscopic features of the esophageal lesions following steroid therapy led to the diagnosis of Crohn's disease of the esophagus in the patient already operated on for a colonic localization. Data from literature are examined with emphasis on the difficulty of the diagnosis.

Radioimmunoassay of lactate dehydrogenase, H forms.

Antisera to H4-lactate dehydrogenase (LDH) were elicited in rabbits, against both human (h) and porcine (p) isoenzymes. 125I-labelled H4-LDH was prepared by electrolytic iodination. A simple and fast procedure (1-h incubation for clinical assays) was set up by using polyethylene glycol for the bound-free separation. The results obtained in the antiserum characterization indicated that the heterologous homotetramer, M4 was completely discriminated in the porcine system, while a weak cross-reaction with human antisera resulted. In both cases, for the hybrid forms, a cross-reactivity level related to the stoichiometric contents of the H-subunit in the tetramers was observed. The H4-LDH from other species was found to be much more effectively disinguished in the porcine than in the human system. The assay for human LDH was further validated in terms of analytical suitability and clinical response. For healthy subjects the mean concentration was 0.46+/-19 micrograms/ml (mean+/-SD). Patients with acute myocardial infarction had levels ranging from 1.2 to 5.9 micrograms/ml.

[Our experience in laparoscopic diagnosis in general and emergency surgery (author's transl)].

After a brief review of the history of laparoscopy starting from the first endoscope, the authors remark on the great usefulness, ease, and essential harmlessness of the procedure. They list all the possible uses of laparoscopy in general and emergency surgery, exemplifying their claims with the illustration of personal cases and recommending widespread use of the method in surgery.

[Current views concerning the etiopathogenesis of reflux esophagitis in children].

Esophagitis is caused by a gastro-esophageal reflux sometimes reflecting anatomical inadequacy of structures that secure the relationships between the cardia and the diaphragm, fundus of the stomach, and other surrounding viscera, but more often due to functional deficiency of lower esophageal sphincter (LES), this representing the main factor for maintenance of the mechanism of cardial continence. Manometric studies of intraluminal pressures in the esophagus have revealed the presence of a high-pressure segment in the distal esophagus, where a mean pressure of 12-13 mm Hg obtains over a length of 3 or 4 cm. In the first two weeks of extrauterine life the LES is between 0.5 and 1 cm long, with a pressure of 3 mm Hg; pressure values in the LES equal adult values at about one month of age, showing that neuromuscular control of the sphincter has been achieved. Gastro-esophageal reflux, however, is very common in the newborn and not enough by itself to cause peptic disease of the esophagus; this requires the concomitance of morphological defects of the esophageal mucosa and/or dynamic-functional disturbances. This, according to the authors, is why esophagitis actually occurs in only about 60% of patients with radiologically and pHmetrically demonstrated gastro-esophageal reflux.

[The use of Dacron prostheses in laparoceles].

BACKGROUND: Purpose of the study was to evaluate indications and efficacy of Dacron prostheses in the treatment of incisional hernias. METHODS: The study has been carried out in a retrospective way; mean follow-up has been 20 months. Surgical setting has been the Institute of Emergency Surgery at the University of Catania, where about 500 abdominal operations are performed every year. Thirty patients affected by incisional hernias have been considered (mean age 66.8 years). In 12 patients the Mayo technique was performed, whereas a Dacron prosthesis was placed in 18 patients. Other than early postoperative complications, patients have been followed by periodical clinical exams in order to find out possible recurrences as well as other late complications. RESULTS: Among 18 patients treated with insertion of Dacron prosthesis no infection, recurrence, bowel fistula, haematoma or dislocation have been observed. Only in one case an intestinal occlusion secondary to adhesions between prosthesis and bowel has occurred; in this patient a new operation has been necessary to remove the prosthesis. CONCLUSIONS: Considering that prostheses have been used in large incisional hernias or in patients with a weak abdominal wall, the high successful percentage (94%) obtained suggests the use of Dacron prostheses which guarantee long stability and minimum risk of recurrences.

[Survey of the frequency of routine diagnostic tests in term pregnancies].

In 420 pregnant women who delivered during the third trimester at the "Istituto di I Clinica Ostetrica e Ginecologica", University of Catania, routine blood tests were performed in 95.5% of cases (401 women), urine tests in 95.5% (401), Hb-phoresis in 42.6% (179), HBsAg in 51.4% (216), TORCH and urine cultures in 37.8% (159), cardiotocograph in 73.1% (307), plasma RIA of E3 and/or HPL in 35% (147), maternal ECG and pseudocholinesterasemia in 83.6% (351) and 37.6% (158) respectively. No routine diagnostic tests were performed in 4.5% (19 women) of cases. Diagnostic tests are less frequently performed in women, plurigravida, and in pregnancies which follow a physiological course. Several diagnostic tests, except for TCTG and HBsAg, are performed more frequently in pregnancies with complications. Lastly, there is a marked difference between the number of diagnostic tests performed and the individual woman's place of residence.
