Inflammatory abdominal aortic aneurysms: does an early stage exist?

Inflammatory aneurysms are characterised by a peculiar clinical (i.e. abdominal-lumbar pain, weight loss and increased ESR) and morphological picture (whitish wall, adhesion to the surrounding organs and thickness greater than 0.5 cm). The lymphomonoplasmacellular infiltrate and the interstitial deposits of collagen define the histological picture of these lesions. The authors describe three abdominal aortic aneurysms macroscopically characterised by parietal edema, hyperemia and hypertrophy of the preaortic lymphnodes. Histological study revealed a conspicuous and widespread lymphomonoplasmacellular infiltrate and interstitial edema. The abdominal-lumbar pain, the increase in ESR and the reactive C protein defined the clinical and laboratory aspects. Serological tests for syphilis, rheumatoid arthritis and lupus erythematosis were negative. The question which arises from these observations is whether these forms represent separate entities or an early stage in the evolution of inflammatory abdominal aortic aneurysms with fibrosis.

Cancer of the esophagus: ten years' experience.

The paper reports the authors' ten-year experience of the surgical treatment of cancer of the esophagus. A total of 625 patients with esophageal carcinoma were observed during the period 1980-89 of whom 490 were admitted to hospital and, of the latter, 172 (35.1%) were operated with a sectile rate of 86% (148 patients). Data from this period were analysed both retrospectively and prospectively using a computerised system. There were 105 radical operations (70.9%) and 43 palliative operations (29.1%). The 3-year actuarial survival rate was 21.7% and the difference between radical and palliative resections was at the limit of significance (p less than 0.1).

Iatrogenic vascular lesions. Pathogenesis and treatment: an 18 year review.

The records of 304 patients operated on for vascular injuries were reviewed; 76 (25%) of these presented an iatrogenic vascular injury: 13 involved the upper limbs, 49 the lower limbs and 14 the neck and trunk. The lesions were due to a vascular catheterism in 40 patients, to orthopaedic treatment in 27 patients, to general surgery procedure in 3 patients, to urologic surgery in 3 and to otorhinolaryngologic surgery in 3. In vascular catheterism the prevalent complications were thromboses and embolisms; 3 patients needed an amputation after the surgical repair. In orthopaedic surgery, vascular complications were linked prevalently to hip surgery, exchange arthroplasty and upper tibial osteotomy. In urologic, otorhinolaryngologic and general surgery, vascular lesions were prevalently related to haemorrhagic complications, followed by incorrect haemostatic manoeuvres. Retroperitoneal fibrosis or previous surgery increased the risk of vascular injuries. Delay in treatment was responsible for post-operative death or incomplete recovery.

Inflammatory aspects in atherosclerotic abdominal aortic aneurysms. A case report.

An important inflammatory reaction was histologically observed in the wall of an abdominal aortic aneurysm in a 42 year-old patient suffering from multifocal atherosclerotic lesions. Histochemical and ultrastructural studies showed an active-stage wall lymphomonoplasmacellular component. The histological appearance and biochemical and microbiological studies excluded specific aortitis, a rheumatic disease or concomitant infectious processes. The morphological relationships between the atherosclerotic lesion and the infiltrate together with the immunophenotyping features of the infiltrate suggest the possibility of a close correlation between the inflammatory process and the atherosclerotic lesion of the wall.

Angiosarcoma in a limb with arteriovenous fistulas and elephantiasis.

Angiosarcoma is a rare malignant tumor of the soft tissues (less than 1% of sarcoma). It may affect various parenchymae (bones, liver, breast), the soft tissues or the skin. In the latter case it may be associated with lymphedema. Onset in the arm is typical with postmastectomy lymphedema (Stewart-Treves syndrome). The forms occurring in limbs with chronic lymphedema not associated with mastectomy are much rarer, with a total of 38 cases occurring in patients with an average age of 46.8 years and with lymphedema present for an average of 20 years. The survival rate for 5 years is 16.6%. The case observed by us had the characteristic onset of the malignant neoplasm on a pre-existing "angiomatosis lymphangiomatosis" pattern also featuring angiographycally detected arteriovenous fistula.

Cardiac arrhythmias following lung resection in patients treated and untreated with digitalis prophylaxis.

Cardiac arrhythmias and failure following lung resection in patients treated and untreated with digitalis prophylaxis have been evaluated. In 82 patients without digitalis (1st group) 11% tachyarrhythmias and 5.7% cardiac failures were noted. In 100 patients treated with digitalis (2nd group) 7% arrhythmias and no cardiac failures were registered. Among cardiac complications only one death in the first group was observed. The mean period of incidence of arrhythmias appears dilated in the digitalis group (3rd vs. 5th postoperative day) and this could be attributed to the early suspension of the drug.

[Evaluation of the sexual role in a group of alcoholics].

The sexual role, evaluated by administration of the Bem Sex Role Inventory in 33 alcoholics, proved significantly different from that seen in a typical Italian sample and that presented by subjects suffering from other organic pathology. No significant differences were observed in psychic symptomatology between alcoholics with sexual role of androginous type with respect to the non-androginous.

Multifocal diffuse glomus tumor. A case report of glomangiomyoma and review of the literature.

The case examined was a multifocal diffuse glomus tumor covering most of the right leg of a 24-year-old woman. The lesion, present at birth, had never caused any symptoms. Macroscopically, it had a simulangiomatous aspect, whereas histologically it was identified as a glomangiomyoma. The Authors have examined 26 (46.4%) of the 56 cases of multiple tumors reported to date. Multiple glomus tumors are benign lesions, which generally appear at an early age (70% by the age of 20), with no clear distinction between the two sexes. The lesions usually occur on the upper limbs, which account for 80% of the cases. Pain is reported in half of the cases. There are 3 histological types: "sensu strictu" glomus tumor, glomangioma and glomangiomyoma; the glomangioma being the most frequent (80.8%) as compared to 19.2% for the glomangiomyomatosis type. No case of "sensu strictu" glomus tumor was observed.

Carotid endarterectomy. Pre- and post-operative monitoring with cerebral SPECT.

In the pre-operative evaluation of carotid endarterectomy, the knowledge of ischemic areas may be helpful to reduce the operative risk. A positive CT scan is often correlated with an increased operative risk. The single photon emission computed tomography (SPECT) allows us to visualize ischemic areas not shown by the CT; these areas are almost always correlated to neurological symptomatology. In patients with positive CT scan, the ischemic areas shown by SPECT are generally larger, because this technique visualize the ischemic area surrounding the cerebral infarct (penumbra). After carotid EA, SPECT is useful to show the hemodynamic modifications induced by this operation. In a series of 15 patients we observed an improvement of the cerebral blood perfusion characterized by the normalization of the blood flow in 7/12 (58%) of the ischemic areas observed pre-operatively), an improvement in 3/12 and a normalization or an improvement in the contralateral hemisphere in 5/7 of the areas. In conclusion SPECT is a useful technique to study the cerebral pathophysiology of both cerebrovascular disease and its surgical treatment.
