Venous Lake

AbstractIntroduction: A venous lake (VL) is a vascular lesion with common occurrence in many patients, manifested as a dark blue-to-violet compressible papule, caused by dilation of venules. The main reasons for the treatment of VL are aesthetic. The haemorrhaging episodes or impairment of oral normal functions are also under considerations. Treatment of lip VL includes surgical excision, selective photocoagulation, cryotherapy, sclerotherapy and electrodessication. The high-intensity diode laser is an option. The 980 nm diode laser is selectively absorbed by haemoglobin and selectively destroys blood vessels, minimising injury to the surrounding healthy skin.Aim: The purpose of this study was to evaluate the effectiveness of diode laser in the treatment of VL lesions with the accent on the postoperative defects and aesthetic results.Methods: 35 patients aged 37 to 71 were included in this study. A 980 nm diode laser was used in noncontact mode, under local anaesthesia in continuous wave (2-3W, for 20-60s). All patients received only one procedure.Results: Healing process was completed within 2 to 4 weeks after treatment with no scarring. None of the typical adverse effects were observed in the process of healing.Conclusions: Selective photocoagulation is an effective method for treatment of VL. Lower morbidity, minimal patient discomfort and satisfactory functional and aesthetic results are favourable for patients. To optimise the results and to reduce the adverse effects, basic knowledge on lasers and laser-tissue interactions is requisite.

Violations of business ethics that occur at this time, become a problem in itself. One of the factors supporting the occurrence of these violations is due to lack of basic knowledge about business ethics and the freedom of business people in carrying out economic activities, as a result many business people are competing in improving market mechanisms, Business should be assessed from a moral standpoint, just like all other human activities also seen from a moral standpoint. Because when not looking at the moral aspect of doing business, business people only think about how to increase sales turnover, and not only increase turnover, but also do things that are not ethical, such as: bribery, corruption, collusion and nepotism, it makes people uneasy . Adverse effects that will occur if a company is immoral and enforces the norms that apply in business ethics then it can have an impact on consumers' distrust of their products and can complicate business development again.

Many considerable investigations focused on the stimulation of therapeutic manners of infected injuries in mice. The exaggerated pathogens that induced wounds were gram-positive like staphylococcal and gram-negative, for example, Pseudomonas aeuroginosa and Acinetobacter baumannii. Acinetobacter can generate a scale range of an infection that may be received in a hospital or any wellness concern facility. In order to know the significance of laser 532 nm with a constant irradiance at various exposure times on the healing process of wounds infected by Acinetobacter baumannii, this study was performed on the BALB/C mice. An elliptical full-thickness skin injury was made on the backside of 45 adult female (BALB/C) mice. Injuries were affected via Acinetobacter baumannii and were randomly assigned into 3 groups. Semiconductor diode continuous wave laser, λ = 532 nm, with output power 40 mW was used. The power density was 5.71 mW/cm2, while the fluencies were 1.7 J/cm2 and 5.14 J/cm2. Fifteen mice were classified according to the times of irradiation. The first group was infected and presented as control, without irradiation. The second group was infected and irradiated for 5 minutes. The third group, likewise, was infected but irradiated for 15 minutes. All groups were subdivided according to the following period, 3, 5, and 10 days, after irradiation and the animals were killed after the treatment. Wound healing was made by measuring the rate of wound closure and histopathological evaluation. The study determined that 532 nm laser therapy had an obvious and positive influence on the healing of infected wounds with fluence (5.14 J/cm2).

The paper deals with the medical application of diode-lasers. A short review of medical therapies is presented, taking into account the wavelength applied, continuous wave (cw) or pulsed regimes, and their therapeutic effects. Special attention was paid to the laryngological application of a pulsed diode laser with wavelength 810 nm, and dermatologic applications of a 975 nm laser working at cw and pulsed mode. The efficacy of the laser procedures and a comparison of the pulsed and cw regimes is presented and discussed.

General Populations

The literature on incest is reviewed. Current knowledge rests on a very insecure scientific basis and has been mainly derived from small, highly selected clinical series. Recently, some important epidemiological studies of general populations have been reported, but the results of prevalence are inconsistent. Overall, however, it appears that incest, when defined in terms of sexual intercourse, occurs in less than 1% of the population, but other forms of intrafamilial sexual activity may affect 10% of females before they are 16 years of age. Some children are more at risk than others. Because information has generally been derived from court or treatment samples, we are unclear about the long-term effects of incest experiences but, overall, the impression is that incest has markedly adverse effects, especially if it is accompanied by violence and threats and is directed, as it usually is, at the young pre-pubescent child.
