[Locoregional complications of stomas. Therapeutic approach].

Principal local complications of ostomies are examined. Etiologic factors and possibilities of treatment are analyzed. These pathologies are often extremely troublesome and their resolution very difficult, unless appropriate therapy is established and, when possible, causal factors removed. However, because of the particular problems of these patients it would be better for them to be assisted by a specialized staff, in qualified centers.

[Varicocele and infertility: clinical framework and therapeutic approach].

A diagnostic-therapeutic protocol which can be used in patients affected with varicocele, in order to obtain a complete clinical study of them and try to improve functional results of therapy, is described. The aims of this protocol are: precise diagnosis of venous refluxes, examination of testicular functionality, detection of possible associated pathologies which can cause infertility, establishment of correct indication to hormonal postoperative therapy. The rapid surgical correction of venous stasis, the treatment of prostatic phlogosis, often concomitant, and, in selected patients, the use of hormonal therapy, can improve functional results in the treatment of this pathology.

Ultrastructural patterns of Helicobacter pylori.

Ultrastructural morphology of the bacterial bodies was studied in 40 Helicobacter pylori positive cases. Two bacterial patterns were identified, which were associated with different modes of contact with the epithelial cells and possibly with different stages of the natural history of the infection.

The anastomotic aneurysms.

The authors describe their experience of anastomotic aneurysm diagnosis and treatment. They are classed into two groups: slowly growing anastomotic aneurysms, which are the most common; and rapidly growing anastomotic aneurysms, which are more infrequent. A follow-up is proposed in order to detect this involvement early, in election. Urgent diagnostic timing is also proposed. Moreover an analysis is made of criteria to follow in their therapy and indications to surgical treatment. In the period from January 1988 to October 1992 we observed 413 patients and 876 anastomosis or arterial sutures in election, discovering 27 anastomotic aneurysms whereas in 6 cases we had patients who were affected with rapidly growing anastomotic aneurysms. These were urgently operated, whereas of the 27 patients with slowly growing anastomotic aneurysms, 22 were operated and in 5 cases we preferred to check them by a close follow-up.

[Surgery vs PTA in sub-inguinal atherosclerosis].

The authors describe their experience in the treatment of arterial occlusive disease of the lower limbs in the femoro-popliteal and tibioperoneal districts, by surgery (proximal or distal femoro-popliteal by-pass or segment by-pass) and Percutaneous Transluminal Angioplasty (PTA), analyzing indications, advantages, limits and complications of the two methods. Immediate and after one and three year results of surgical by-pass and PTA are compared. On the whole, in the patients in which we performed a surgical by-pass, we obtained slightly better results. Anyway, in the second stage of the arterial occlusive disease and in patients affected with short arterial stenosis and/or obstructions, PTA represents the best treatment.

First and second metatarsophalangeal joint dislocation. A case report.

A case of dislocated first and second metatarsophalangeal joints was reported along with the mechanics and mechanism of injury. The practitioner must be familiar with the mechanism of injury and radiographic classification to determine the proper indications for closed versus open reduction. The authors' review of the literature did not reveal a similar case involving a dislocation of the first and second metatarsophalangeal joints.

Gastric metaplasia in duodenal bulb and Campylobacter-like organisms in development of duodenal ulcer.

Multiple biopsies were taken from 50 patients with endoscopic appearance of duodenitis in order to study the relationship between gastric metaplasia in duodenum and the presence of Campylobacter-like organisms (CLOs) and the development of duodenal ulcer disease. Metaplasia was found in at least one biopsy specimen from 46 of the 50 patients; CLOs were seen in 25 of the 50 patients, only in metaplastic areas. In four cases a "transitional epithelium" with the presence of cells containing few apical mucoid granules and absorbent-type brush border as well as goblet cells was seen. In two cases, this epithelium was colonized by a small number of CLOs. Gastric heterotopia appears to be a rare condition.

Campylobacter-like organisms, nonsteroidal anti-inflammatory drugs and gastric lesions in patients with rheumatoid arthritis.

A histological study was performed in order to evaluate the prevalence of Campylobacter-like organisms (CLO) and gastric antral lesions in 85 rheumatoid arthritis (RA) patients using NSAIDs, and in 100 nonrheumatoid outpatients comparable in terms of sex and age, not using NSAIDs. Histological evidence of gastritis was a common finding both in RA patients (88.2%) and in nonrheumatoid outpatients (89.0%). On the other hand, CLO were detected in a significantly lower proportion (p less than 0.001) of RA patients than outpatients (30.6 and 59.0%, respectively). Considering each NSAID used separately (aspirin, diclofenac sodium and ketoprofen), no significant difference in the presence of CLO in the three groups was found; in the small group of patients treated with aspirin, however, bacteria were never detected. MICs of each NSAID used against 15 isolates of Campylobacter pylori were also determined.

Patterns of physical modes of contact between Campylobacter pylori and gastric epithelium: implications about the bacterial pathogenicity.

Since the exact mechanisms of the pathogenicity of Campylobacter pylori are not known, we performed an ultrastructural study with the aim of focusing on patterns of possible physical contact between C. pylori and gastric epithelium, and of considering them in relation to the bacterial pathogenicity. Among 20 random consecutive patients referred for routine gastroscopy, we studied ultrathin sections from the 11 patients with Campylobacter-like organisms, and recognized three patterns of physical contact between bacteria and epithelial cells. These patterns seem in accord with published data of C. pylori toxicity, and they could represent different evolutive stages of the infection.

Dead fecal yeasts and chronic diarrhea.

The authors report 20 patients in whom a large number of dead or severely damaged yeast cells, supposedly Candida albicans yeasts, were the possible cause of chronic recurrent diarrhea and abdominal cramps. It is suggested that the presence of large numbers of these microorganisms in stools may be considered among the possible etiologies of diarrhea in the 'irritable bowel syndrome'. The possible source of these yeast-like cells, the causes of cell damage, and the mechanisms by which these organisms may induce diarrhea should be investigated.
