[Comparison of 2 lacrimal punctal occlusion methods].

PURPOSE: To study and compare two methods for canalicular occlusion: Cautery and Punctal Patch. METHOD: The study included fourty patients divided in two groups of 20 patients. The end point was 4 occluded puncti. The first group underwent deep cauterization resulting in occlusion of the full vertical aspect of the canaliculus. The second group underwent punctal patch technique for canalicular occlusion. Differential parameters were the following: time of intervention, ease of use, risks and precision. In the post operatory, discomfort, subjective and objective improvement in ocular surface as well as long term result of each technique was analysed. RESULTS: Time of intervention was longer for punctal patch compared to cautery. Both methods exhibited similar ease of use and improvement in ocular surface. Precision was high in punctal patch technique showing complete and final occlusion and no punctum needed reopening, while cautery technique presented 20% rate of reopening intervention. Postoperatory discomfort and irritation were remarkably evident with punctal technique, while minimal in cautery technique. CONCLUSION: Survival analysis after one year follow up, showed a higher rate of advantages for punctal patch technique over cautery technique.

The effects of total lymphoid irradiation upon corneal vascularization in the rat following chemical cautery.

The effect of total lymphoid irradiation (TLI), a form of radiotherapy known to suppress the number of circulating lymphocytes, on corneal neovascularization was assessed in rats. The corneas of TLI-treated rats were cauterized with silver/potassium nitrate one day after delivering gamma irradiation in five equal fractions (10 Gy total dose). Corneal neovascularization was assessed quantitatively by computerized image analysis in corneal flat preparations 4 days after corneal injury following perfusion of the circulation with India ink. TLI reduced the total leukocyte, lymphocyte, neutrophil, and platelet counts below preirradiation levels. The number of circulating lymphocytes was reduced more than neutrophils and platelets. TLI caused a predominance of cytotoxic/suppressor lymphocytes. Tissue examinations 4 days after TLI disclosed an absence of the thymus, as well as a markedly reduced number and size of lymph nodes. TLI rats had less corneal vascularization than nonirradiated controls. Our findings are consistent with the hypothesis that leukocytes play an important role in the pathogenesis of corneal angiogenesis following chemical cautery, but this study does not indicate how TLI suppresses corneal neovascularization.

Pleuroscopy and cautery control of intrathoracic hemorrhage with a flexible fiberoptic bronchoscope.

Intrathoracic hemorrhage from adhesions torn by a spontaneous pneumothorax is relatively uncommon. Continued hemorrhage from such adhesions after the evacuation of 1,500 ml of blood would usually require thoracotomy for control. Through a flexible fiberoptic bronchoscope, we confirmed the source of hemorrhage and cauterized the bleeding point. This case illustrates another application for pleuroscopic examination, further broadening the use of the flexible fiberoptic bronchoscope.

The expression of nuclear factor kappa B in inflammation-induced rat corneal neovascularization.

PURPOSE: To investigate the involvement of the nuclear-transfactor-kappa B (NF-kappa B) in the rat model of inflammation-induced corneal neovascularization (CNV). METHODS: The CNV model in Sprague-Dawley rats was induced by alkaline cauterization of the central cornea. The corneas were examined by a slit lamp microscope. NF-kappa B was assayed by Western blot. Vascular endothelial growth factor (VEGF) protein was evaluated by immunohistochemistry. VEGF mRNA levels were determined by reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: Morphologically, the CNV was shown on the second day after cautery. In corneas after cautery, NF-kappa B protein increased 6 hours after cautery, peaked 4 days after cautery, and decreased to near baseline by day 14. VEGF protein and mRNA increased gradually in the early stage after cautery, reached the highest level on the fourth day, and then decreased to near baseline slowly after 7 days. CONCLUSIONS: The activated NF-kappa B was up-regulated in the early stage of CNV of rat induced by cauterization, which suggests it may participate in the pathogenesis of wound healing, inflammation, and neovascularization processes in the cornea.

Evacuation/cautery vitreous needle.

Since hemostasis and passive suction to remove preretinal blood are important elements to the vitrectomy surgeon, a new disposable evacuation/cautery needle has been developed to accomplish these two objectives. This instrument allows the surgeon to clear the vitreous proximate to the bleeding site and cauterize the vessels without changing instruments.

The efficacy of silver nitrate cauterization for pyogenic granuloma of the hand.

PURPOSE: We report a series of pyogenic granulomas of the hand treated effectively in the office with silver nitrate cauterization. METHODS: Twelve patients with 13 pyogenic granulomas of the hand were treated. The average duration of symptoms was 2 months. Masses were removed bluntly, pressure was held proximal to the lesion to effect hemostasis, and the base of the lesion was cauterized with silver nitrate applicators. After treatment patients were instructed to keep the lesions absolutely dry for 2 weeks. RESULTS: Complete resolution of the pyogenic granuloma was achieved in 85% of patients after an average of 1.6 treatments (range, 1-3 treatments). CONCLUSIONS: Pyogenic granuloma of the hand can be treated simply and effectively with silver nitrate cauterization in the office setting.

Technique for vestibular neurotomy in the rat.

A technique for vestibular neurotomy in the rat has been developed. Removal of the tympanic membrane and ossicles through the external auditory meatus permits access to the auditory bulla. After the pterygopalatine artery has been cauterized, and the electrode may be introduced through the oval widow. The vestibular branch of the VIII nerve can then be cauterized with the electrode without direct visualization.

Long-term comparison between submucosal cauterization and powered reduction of the inferior turbinates.

OBJECTIVES/HYPOTHESIS: To evaluate the results of powered turbinoplasty and to compare these with submucosal cauterization of the inferior turbinates. STUDY DESIGN: Prospective, randomized, comparative surgical trial. METHODS: Nineteen patients with medication-resistant chronic nasal obstruction caused by inferior turbinate hypertrophy were randomized to undergo powered turbinoplasty on one side and submucosal cauterization on the other. For each side, an extensive assessment (symptom scoring, endoscopic scoring, and acoustic rhinometry) was recorded preoperatively and on week 1, week 3, month 3, year 1, and year 5 postoperatively. RESULTS: Powered turbinoplasty was superior to submucosal cauterization on all aspects of the assessment. A significant difference (P < .05) was noted for postoperative crusting, endoscopical scoring of turbinate size, and acoustic rhinometry measurements of nasal cavity volume and mean area at the level of the nasal valve. In addition, the results of powered turbinoplasty were still apparent on long term follow-up, whereas submucosal cauterization was associated with a recurrence of turbinate hypertrophy. CONCLUSION: Performing a powered turbinoplasty leads to decreased patient morbidity during the postoperative healing and to a better control of long-term results when compared with submucosal cauterization.

Inhibition of bladder tumor cell implantation in cauterized urothelium, without inhibition of healing, by a fibronectin-related peptide (GRGDS).

BACKGROUND: Local recurrence after transurethral resection of bladder tumors (TURB) is common and might be diminished if free tumor cells within the bladder are prevented from reattaching. METHODS: In vitro inhibition of murine bladder tumor cells to an approximation of urothelial matrix with agents that might block attachment to components of the extracellular matrix, and in vivo inhibition of attachment in cautery-injured murine bladder. RESULTS: GRGDS, (0.1-2.5 mg/ml), a fibronectin-related peptide, mannose-6-phosphate, (0.1-20 mg/ml), a carbohydrate, and heparin (1-625 units/ml) all inhibited attachment in vitro in a dose-dependent fashion. YIGSR (0.1-2 mg/ml), a laminin-related peptide, did not. Mannose (10 mg/ml) did not significantly inhibit attachment of tumor cells to cauterized urothelium in vivo, whereas there was a 77% reduction of attachment in bladders irrigated with GRGDS (6.25 mg/ml) (p < 0.05), and the appearance of subsequent tumors in the bladder was inhibited. Finally, GRGDS (6.25 mg/ml) did not inhibit healing of the cautery ulcer. CONCLUSIONS: RGD-containing peptides may be useful as adjuvant therapy to decrease local recurrence after TURB and perhaps in other circumstances in which tumor cells spilled into a wound or body cavity threaten surgical success.

The vas after vasectomy: comparison of cauterization methods.

A histologic study of the vas ends was carried out in 21 patients undergoing vasovasostomy. All had undergone prior vasectomy by the same surgeon, with a technique identical except for the type of cautery used to seal the vas ends. A superior sealing of the vas, as shown by fewer cases of vasitis nodosa and spermatic granuloma, followed use of the thermal cautery ("red-hot wire") than the electrosurgical cautery (23% vs 60.7% suboptimal sealing rate). The thermal cautery is a superior method of sealing the vas at vasectomy.
