Differential activity and activation of Bacillus thuringiensis insecticidal proteins in diamondback moth, Plutella xylostella.

Whole-crystal preparations from strains HD-1 and HD-133, activated Cry1Ab and Cry1C toxins as well as Cry1Aa, Cry1Ac, Cry1D, and Cry2Aa protoxins were tested for toxicity to 2nd-instar larvae of the diamondback moth, Plutella xylostella. Mortality data recorded after 2 and 5 days provided different results that were related to differential rates of solubilization, activation, and degradation of insecticidal crystal proteins. The two most active proteins are Cry1Ab and Cry1C, which are both present in HD-133. The Cry1Ab protoxin is activated within 2 days, whereas activation of the Cry1C protoxin occurs between 2 and 5 days. HD-133 is more active than HD-1 immediately after infection and remains toxic over 5 days owing to the sequential activation of its crystal components. Solubility properties of crystals and rates of activation of protoxins influence the overall toxicity of HD-1 and HD-133 to the diamondback moth.

[Adenocarcinoma in ileocystoplasty].

Case report of an adenocarcinoma in ileocystoplasty in a 54-year old female that at the age of 24 had undergone right nephrectomy and partial cystectomy surgery followed by vesical extension with ileon due to urinary tuberculosis. Discussion on the rare incidence of this condition, its diagnostic features, the need for long-term follow-up and the relevance of a broad resection of the affected intestinal portion.

[PSA levels and its relationship with digital examination, age, and score of prostatic symptoms].

Between November 1992 and March 1993 our Service conducted a campaign for early detection of prostate disease among the male population of Vigo. The study focused in the relationship of PSA with the age, rectal examination and prostate symptomatology score. In view of the results obtained it has been concluded that PSA levels increase gradually as a function of age, volume and prostate symptomatology score.

[Cushing syndrome caused by macronodular hyperplasia ACTH-independent].

Case report of a 49-year old male patient who presented with signs and symptoms in agreement with Cushing's Syndrome, the etiology of which was shown to be an ACTH-independent macronodular hyperplasia. In such cases, the therapeutical choice is bilateral adrenalectomy which was adopted by us using a posterior approach. The relevance of the clinical diagnosis and therapeutical aspects of this condition are reviewed.

[Enzyme-induced masculinization].

Contribution of two cases of congenital adrenal hyperplasia by blockade in the 21-hydroxylase enzyme synthesis. Diagnosis was reached from the clinical signs and symptoms (virilization syndrome), and was confirmed by radiological and laboratory tests. Hormone treatment was done with hydrocortisone and fludrocortisone, but surgical correction of external genitalia was required to improve cosmetic appearance.

[Conn's syndrome].

Adrenal hypertension is an uncommon phenomenon. When seen in association with hypokalemia the existence of primary aldosteronism, the most frequent cause of which is an adenoma of the adrenal gland cortex, should be suspected. This paper contributes one case of primary aldosteronism treated by unilateral resection of the adrenal adenoma, with no surgical complications and good medium-term results.

[Radical cystectomy with orthotopic urinary diversion in patients older than 70 years of age].

Some patients with infiltrant vesical cancer can be treated successfully with radical cysto-prostatectomy and urinary by-pass and increasingly more authors publish successful results in series of selected patients over 70- and 80-year old. Between February 1988 and July 1996, 18 radical cystectomies with orthotopic urinary by-pass were performed in the Urology Service, Policlinico Vigo, in patients over 70 (range 70-84 years), with an operative mortality rate of 11%. 8 patients (44%) developed immediate complications and 9 patients (50%) presented distant complications. Overall mortality in our series was 33.3% and survival 66.6% after a mean follow-up of 30.7 months. We believe orthotopic-continent by-pass is a valid alternative with operative mortality and complication rates similar to those of ileal ducts, with the advantage for the patient of avoiding permanent urinary stoma.

[Partial nephrectomy for renal cancer in patients with a normal contralateral kidney].

There has been a growing interest over the last few years in partial nephrectomy as the elective surgery for renal cancer in selected groups of patients with normal contralateral kidney. Between July 1990 and April 1996, 14 partial nephrectomies were performed in our service in patients with presumed diagnosis of renal cancer and normal contralateral kidney 10 of which had histological diagnosis of renal carcinoma and 4 showed absence of malignancy. From the analysis and discussion of these cases it can be deduced: 1) partial nephrectomy in selected groups of patients is an oncologically valid technique; 2) computerized tomography is a highly sensitive method for detection of renal cancer carrier patients, although it presents low specificity, mainly in small tumours, resulting in a number of false positive cases that must be considered when deciding the surgical technique; 3) tumour topography should not exclude conservative surgery of the kidney; 4) patients should be available for follow-up.

[Malignant endometriosis].

Presentation of two case reports of severe and multiple urinary tract involvement by endometriosis due to the low frequency of this disorder. Although this is a benign condition, the term "malignant" endometriosis has been used because of the significant consequences it may have for the urinary tract, since it may compromise both excretory systems with a likely vital risk.
