’Purpose. To observe the clinical efficacy and safety of carbon dioxide laser combined with ALA photodynamics in the treatment of condyloma acuminatum. Method. A total of 211 patients with condyloma acuminatum admitted to our hospital from April 2018 to June 2021 were selected as the observation object. They were divided into the intervention group (CO2 laser combined with ALA photodynamic therapy, 125 cases) and conventional group (CO2 laser treatment, 86 cases), and the efficacy and incidence of adverse reactions between the two groups were compared. Result. The total effective rate of the intervention group (96.00%) was significantly higher than that of the conventional group (84.88%) ( P < 0.05 ). The total incidence of adverse reactions in the intervention group (8.00%) was lower than that in the conventional group (32.56%) ( P < 0.05 ). Univariate analysis showed that the patient’s smoking history, drinking history, course of disease, wart area, and number of sexual partners were related to the short-term prognosis ( P < 0.05 ). Multivariate logistic regression analysis showed that the patient’s course of disease, the area of the wart body, and the number of sexual partners were independent factors affecting the prognosis of patients with condyloma acuminatum ( P < 0.05 ). Conclusion. Carbon dioxide laser combined with ALA dynamics treatment of condyloma acuminatum significantly improves the clinical efficacy, does not increase the incidence of adverse reactions, and has important clinical therapeutic value. The course of the disease, the area of the wart, and the number of sexual partners are independent factors affecting the prognosis of patients with condyloma acuminatum.

Abstract Since 1977, we have used a 170-W CO2 laser manufactured in Shanghai. In animal studies we found less temperature increase in neighboring cerebral tissue after laser vaporization (0.8°C) than after bipolar coagulation (1.4°C) or monopolar coagulation (8°C). Some factors affecting the reaction of cerebral tissue to CO2 laser irradiation are discussed. This laser was also used in 30 craniotomies: 20 for gliomas, 5 for meningiomas, 4 for metastases, and 1 for a vascular malformation. No obvious cerebral or systemic adverse effects were seen, but the length of follow-up is insufficient to demonstrate an increased survival rate.

Risk Taking Behaviors

Undergraduate students at an urban, public university were asked if they had ever attempted to dissuade a sexual partner from using condoms. Over 17% of the men and nearly 15% of the women admitted to having done so, and twice as many said that a sexual partner had attempted to dissuade them. Responses to a questionnaire indicated that individuals who had attempted to dissuade use of condoms did not show a greater tendency to engage in nonsexual risk-taking behaviors. Despite their claims that attempts to dissuade partners from using condoms occurred in committed relationships, condom dissuaders did show evidence of engaging in other high-risk sexual behaviors, e.g., greater number of sexual partners, greater number of sexually transmitted diseases.

Laser Effect

While much is known regarding the effect of lasers on the retina, little study has been done on the effect of lasers on cornea, because of the limitation of the size of the material. Using a combination of electron microscope and several newly developed cytochemical methods, the effect of laser can now be studied on eye for the purpose of correlating functional and morphological damage. The present paper illustrates such study with CO2 laser on Rhesus monkey.
