A 49-years-old man was operated on of a descending thoracic dissecting aneurysm by means of a heparin-less external Gott shunt. A review of spinal irrigation, neurological deficits postclamping of the descending thoracic aorta and methods of spinal preservation in aortic surgery are presented.
Two patients with severe coronary artery disease and significant stenosis of the left internal carotid artery were operated upon. A combined or simultaneous operation was performed in both, carotid endarterectomy plus coronary artery bypass surgery was performed. The patients are symptoms-free after the operation and with evidence of satisfactory reconstruction in the carotid and coronary arteries. A review of the topic simultaneous revascularization of the carotids and coronary arteries in presented.
Authors explain their experiences with eight patients (14 affected limbs) with a popliteal artery entrapment syndrome. Classification, diagnosis and treatment were reviewed. Six limbs, with any malformation and presenting as a unique sign an important hypertrophy of their intern gastrocnemius muscle, couldn't be classified. As a result, a new classification of this pathology is presented being based on the anatomical and arteriographic aspects as well as oh the surgical indication. The important correlation between anomaly, physical complexion typus athletic and sports is noted.
We researched the microbial etiology of 5,836 diarrheal processes in outpatients and inpatients at the Social Security Hospital in Cádiz, for the purpose of evaluating their microbiological and epidemiological characteristics. Bacterial gastroenteritis accounted for 51.6% of the cases, while 31.7% were viral and 16.6% were protozoal in origin. Salmonella enterica (35.6%) is the most frequently involved microorganism, especially in the summer, followed very closely by Rotavirus (31.7%). The incidence of Campylobacter jejuni (13.8%) and Cryptosporidium (7.1%) is also important. Due to the influx of tourists and their consumption of seafood, eggs and derivatives, acute gastroenteritis is a frequent pathology in our city. The number of cases has increased in recent years, and those of an infectious nature represented 27.2% of all cases recorded for the period 1988-1989.
We studied forty children with "Febrile-eosinophilic-Syndrome". They presented Fasciola Hepatic infection confirmed by: Fever, high eosinophils and abdominal pain. 82% used to eat watercress. All of them had positive biopsies-laparoscopies-intradermo-reaction and also reaction to Fasciola antigen. We present the results of and epidemic in Cuba during 1983.

This retrospective study evaluated 32 patients with primary gastrointestinal lymphoma managed at Belen Hospital, Trujillo, Peru, from 1966 to 1994 to determine their clinicopathologic findings and identify those prognostic factors that influenced in the 5-year survival. Median age was 44.2 years. The male to female ratio was 1.3:1 and seventh decade was the most involved. Abdominal pain, the predominant symptom, was present in gastric (100%) and intestinal (91%) lymphoma. Small intestine was involved in 62.5% cases, followed by stomach (28.1%). Most common stage was II1E (50%) and predominant histological was high grade-MALT type lymphoma (81.3%). Five year survival rate was 29% for those who received some kind of treatment (n = 30): It was 38% for whom underwent surgery plus chemotherapy and/or radiotherapy compared to those who only underwent surgery (23%) (p < 0.05). Factors as histological type (p < 0.005), stage (p < 0.005) and tumoral size (p < 0.05) were associated with long term survival. We conclude that early diagnosis is important to define management in these patients and post-operatory adjuvant treatment should be considered to obtain a longer survival.
