Positive staining with Congo red in tissues with heat artifact due to cautery.
(36/72)
Congo red staining is rarely the source of false positives for amyloid. On the other hand, the heat artifact due to cautery in surgical specimens adopts some hyaline features, which can mimic amyloid deposits many times. Therefore, we decided to investigate the behavior of these artifacted areas with some of the ancillary techniques that are commonly used when diagnosing amyloidosis: Congo red staining (with and without treatment of the tissue by permanganate of potassium); Thioflavin T; polarized light and immunohistochemistry (for A amyloid, lambda chain and kappa chain). For that, 10 biopsies of different organs were selected with the condition that there was "evidence of heat artifact border". Our results showed that the artifacted border is strongly positive for Congo red (even after treatment with permanganate of potassium). It also showed apple-green birefringence when observed under polarized light. Nevertheless, it failed to express any of the markers investigated in the immunohistochemical study. (+info)

Endoscopic cauterization of the sphenopalatine artery in persistent epistaxis.
(38/72)
The management of epistaxis remains to be a challenging problem for most ENT surgeon especially posterior epistaxis. Most cases are managed by placement of posterior nasal packs or balloons and failure leads to more invasive techniques, involving ligation of the internal maxillary artery. The above management is associated with significant patient complication and morbidity. Endoscopic ligation or cauterization of the sphenopalatine artery has emerged as a viable and minimally invasive alternative. We have performed endoscopic cauterization of nine sphenopalatine arteries in eight patients with no further episodes of epistaxis and complications, with an average follow-up of 25 months. The mean age of the patients was 52.75 years. Fifty percent of the patients had a history of hypertension. (+info)
Effects of a dominant follicle on ovarian follicular dynamics during the oestrous cycle in heifers.
(39/72)
Two hypotheses were tested: (1) a dominant follicle causes regression of its subordinate follicles, and (2) a dominant follicle during its growing phase suppresses the emergence of the next wave. Cyclic heifers were randomly assigned to one of four groups (6 heifers/group): cauterization of the dominant follicle of Wave 1 or sham surgery (control) on Day 3 or Day 5 (day of ovulation = Day 0). Ultrasonic monitoring of individually identified follicles was done once daily throughout the interovulatory interval. The onset of regression (decreasing diameter) of the largest subordinate follicle of Wave 1 was delayed (P less than 0.01) by cauterization of the dominant follicle of Wave 1 on Day 3 compared to controls (mean onset of regression, Days 10.8 +/- 2.1 vs 4.3 +/- 0.4). Cauterization of the dominant follicle of Wave 1 on Days 3 or 5 caused early emergence (P less than 0.01) of Wave 2 when compared to controls (Day-3 groups: Days 5.5 +/- 0.4 vs 9.6 +/- 0.7; Day-5 groups: Days 7.0 +/- 0.3 vs 9.1 +/- 0.4). The results supported the two hypotheses. In addition, cauterization of the dominant follicle of Wave 1 on Days 3 or 5 increased the incidence of 3-wave interovulatory intervals. (+info)
