RESUMO

BACKGROUND: Sentinel lymph node (SLN) dissection in the management of high-risk melanoma and other cancers, such as breast cancer, has recently increased in use. The procedure identifies an SLN by intradermal or intraparenchymal injection of an isosulfan blue dye, a radiocolloid, or both around the primary malignancy. METHODS: At the time of selective SLN mapping, 3 to 5 mL of isosulfan blue was injected either intradermally or intraparenchymally around the primary malignancy. From October 1997 to May 2000, 267 patients underwent intraoperative lymphatic mapping with the use of both isosulfan 1% blue dye and radiocolloid injection. Five cases with adverse reactions to isosulfan blue were reviewed. RESULTS: We report 2 cases of anaphylaxis and 3 cases of "blue hives" after injection with isosulfan blue of 267 patients who had intraoperative lymphatic mapping by the procedure described above. The 2 patients with anaphylaxis experienced cardiovascular collapse, erythema, perioral edema, urticaria, and uvular edema. The blue hives in 3 patients resolved and transformed to blue patches during the course of the procedures. CONCLUSIONS: The incidence of allergic reactions in our series was 2.0%. As physicians expand the role of SLN mapping, they should consider the use of histamine blockers as prophylaxis and have emergency treatment readily available to treat the life- threatening complication of anaphylactic reaction.

RESUMO

The aim of this study was to describe and evaluate the laparoscopic treatment of esophageal achalasia in nine patients over a 35-month period. Five trocars were used to perform a Heller's myotomy to completely eliminate the cardial high-pressure zone, under manometric control. Intraoperative manometry also was used to calibrate a pick degrees 360 Rossetti's antireflux wrap. A complete regression of symptoms was observed postoperatively in seven of nine patients (77.8%); in two patients (22.2%) a moderate dysphagia persisted, but it disappeared 3 and 6 months, respectively. Only one intraoperative complication (esophageal perforation, recognized and laparoscopically repaired) occurred. At the present follow-up of 18 +/- 5.34 months (range 6-35), no dysphagia or symptoms related to reflux have been observed. Laparoscopic treatment of esophageal achalasia is considered a safe and effective procedure, and the results of this procedure are comparable with those of the open technique. Advantages common to other laparoscopic techniques are emphasized.

RESUMO

Medical and biochemical analysis were performed on 58 patients with chronic alcoholism. In accordance with medical characterisation, patients were divided in three groups: A (patients having only hepatopathy), B (patients with hepatopathy and neuropathy) and C (patients having only alcoholic neuropathy). Simultaneously, several parameters related to heme biosynthesis were examined. Urinary delta-aminolevulic acid (ALA), porphobilinogen (PBG) and porphyrins and fecal porphyrins measurements did not show significant difference among all studied groups. The activities of ALA-dehydratase (ALA-D), uroporphyrinogen-I-synthase (URO-I-S) and uroporphyrinogen-III-synthase (URO-III-S) were monitored in peripheral erythrocytes. From the enzymes measured, only ALA-D levels in groups B and C were significantly depressed (p < 0.002) compared with normal subjects. The decrease in ALA-D correlated with the degree of neuropathy.

RESUMO

The problem of surgical fixing for incisional hernia is still far from a final solution. Over the past few years, prostheses have been used in addition to traditional plastic surgery. The aim of this experimental study was to assess the efficacy of traditional techniques in comparison to modern methods using prostheses. For this purpose, two original experimental models were designed to assess parietal resistance. Ninety-six Wistar rats were subdivided into 4 group: 1) control; 2) "waistcoat" plastic surgery; 3) plastic surgery using a vicryl prosthesis. With the exception of rats in group 1, a lozenge-shaped section of abdominal wall was removed from all other rats and, subsequently, the wall was repaired using the above-mentioned methods. Rats were killed after 30-60-120-180 days and the abdominal walls were subjected to traction and pressure using specially designed experimental models. For the first 30 days, the walls with dacron and vicryl prostheses behaved in a similar way, and showed a greater resistance than the other two groups; but after day 120, the resistance of dacron prostheses was considerably greater than that of the other groups studied. In conclusion, plastic surgery based on the use of nonreabsorbable prostheses is now more efficacious than traditional plastic surgery in the surgical treatment of incision hernia.

RESUMO

PIP: This retrospective study demonstrates the efficacy of ultrasound as it is used in the detection of abnormal pregnancy early in the gestational period and as a guide for voluntary abortion. The study also points out that the extrahospital centers whose duty it is to select and refer patients to the hospital are not capable of such selection. (author's)^ieng

RESUMO

Adrenal epinephrine (E) release after hemorrhage in anesthetized dogs is blunted by acute nephrectomy and restored by angiotensin II infusion. In the present study, we report the effect of converting enzyme inhibition by SQ 20881, a decapeptide, and of competition inhibition of angiotensin II by saralasin (1-Sar-8-Ala-Ang-II) on reflexly stimulated adrenal release of E and norepinephrine (NE) in three groups of acutely anephric dogs. Aortic catheters and adrenal vein to femoral vein Silastic shunts were placed in dogs anesthetized with pentobarbital and mechanically ventilated. Adrenal secretion rates were calculated from adrenal vein to aorta catecholamine concentration differences divided by measured adrenal venous flow. Catecholamine concentrations were determined with trihydroxyindole technique. Blood samples were obtained before and 15, 30, and 60 min after rapid hemorrhage to a stable mean arterial pressure of 50 mm Hg. Saralasin infusion (10 microgram/kg/min) supported adrenal E release in anephric hemorrhaged dogs toward secretion rates comparable to those seen in intact dogs. Anephric SQ 20881 (approximately 0.5 microgram/kg) recipients had delayed (60 min) augmented adrenal E and NE release after hemorrhage. In resting animals not reflexly stimulated by hypovolemia, neither drug provoked adrenal E or NE release. These results suggest an agonist effect of saralasin on reflex adrenal E release and increased responsiveness of the stimulated adrenal medulla under the influence of converting enzyme inhibition.

RESUMO

A comparison was made of the gross and microscopic wound healing and tissue reactivity between stainless steel wire, polypropylene and silk in anastomoses in the u-prepared colon of the dog. While all anastomoses healed irrespective of the suture material used, wire was associated with the least inflammatory response, silk the most and polypropylene intermediate, its low reactivity approaching that of wire. A clinical trial of Prolene for 71 varied anastomoses between pharynx, esophagus, stomach and colon in 47 patients undergoing esophageal resection and reconstruction or bypass was done. In four of the seven anastomotic disruptions which occurred, causative factors unrelated to the suture material could factorily in the remainder of these patients. Monotive suture which works well in esophageal and gastrointestinal anastomoses.

RESUMO

The results of major pulmonary resection in 58 patients greater than 70 years of age were reviewed. The histological distribution and extent of nodal metastases in this age group are the same as in younger patients. The absolute five-year survival rate for the 55 patients undergoing curative resection was 30% (17 patients). It was 36% (11 patients) for those patients with squamous cell carcinoma and 22% (5 patients) for those with adenocarcinoma. The operative mortality was only 14% (8 patients). Of the 49 patients treated by lobectomy, 17 lived five years or more free of disease, whereas none of the 6 patients treated by pneumonectomy survived five years. The five-year survival rate of 30% in this series of elderly patients treated by major pulmonary resection makes resections in such patients with bronchogenic carcinoma worthwhile.
