Unilateral Injury

1. Injury to one side of the face, whether on the frons or an antennal patch, affects the orientation of adult locusts to a lamp. For the first 5 days after injury most of them turn the injured side towards the lamp. This tendency is lost or reversed after the fifth day. The change is most evident with a lamp of relatively high power (100 W.); with weaker lamps (60 or 40 W.) the differences are not statistically significant after five days. 2. This phenomenon explains the finding of previous authors that the injured side is usually turned away from a lamp. When the results of numerous tests are added together, those obtained more than 5 days after injury can swamp the earlier ones. 3. Suggested interpretations include the possibility that injury makes the damaged part ‘numb’ until type II neurones are formed in the healed area.

Among contact sports, the practice of martial arts offers a greater risk of causing dental trauma and fractures as contact with the face is more frequent. The primary objective of the research is to evaluate the incidence of mouthguard use, and the secondary objective is to verify which type has a greater predominance and the difficulties in its use correlating to the type of mouthguard used. A documentary study was carried out with 273 athletes of different contact sports, among them: MMA, Boxing, Muay Thai, Jiu-Jitsu, and Taekwondo of the city of Campos dos Goytacazes, Rio de Janeiro, Brazil. It was concluded that the most commonly used mouthguard is PB Boils and Bites - Type II and its level of approval is poor, interfering with the athletes’ performance, mainly in relation to the breathing factor.

Abstract Context: Facial artery is usually the main artery supplying the face. It gives three named branches on the face, the inferior labial, the superior labial and the lateral nasal and continues as the angular artery. Face is also supplied by the transverse facial artery and the arteries accompanying the cutaneous nerves. Aim: In the present study, variations of facial artery on face were observed. Settings & design: Department of Anatomy, Kasturba Medical College, Manipal. Material & method: The present study was performed on 38 males and 12 females' formalin-fixed hemi-faces. Diameter of facial artery was noted at two specific points using a fine microcaliper. Results: The variations were divided into 3 categories. Out of 38 male hemi-faces, 100% right and 78% left hemi-faces belonged to type I category; 22% left hemi-faces belonged to Type III category. Out of 12 female hemi-faces, 80% right and 80% left hemi-faces belonged to Type I category, 18% left hemi-faces belonged to Type II category and 20% right and 2% left hemi-faces belonged to Type III category. Premasseteric branch was observed in 4 hemi-faces; a duplex with a prominent lateral angular branch was observed in 4 hemi-faces and anenlarged transverse facial artery was seen in 2 hemi-faces. The diameter of facial artery at its origin and at the antero-inferior angle of masseter muscle was larger in males. Conclusion: This study shows that the variations in the branches and the diameter of the facial artery were relatively larger in males when compared to females.

The Face

A new approximation is proposed for testing the equality of k independent means in the face of heterogeneity of variance. Monte Carlo simulations show that the new procedure has Type I error rates that are very nearly nominal and Type II error rates that are quite close to those produced by James’s (1951) second-order approximation. In addition, it is computationally the simplest approximation yet to appear, and it is easily applied to Scheffé (1959) -type multiple contrasts and to the calculation of approximate tail probabilities.

Abstract Objective This study aimed to appraise the efficacy of a 577-nm high-power optically pumped semiconductor laser (HOPSL) for the treatment of inflammatory acne. Methods The study included 50 patients with acne vulgaris (inflammatory type), 14 men, and 36 women; patient ages ranged from 16 to 35 years. The left side of the face was treated with a single pass of a 577-nm high-power optically pumped semiconductor laser (HOPSL) every 2 weeks for 3 sessions. The severity of acne examined prior to the first session and 4 weeks after the last session (Investigator's Global Assessment of acne severity, IGA; single lesion count). Results At baseline, no statistically significant difference in the severity of inflammatory acne lesions between both sides was observed. One month after the final session, a significant improvement (IGA reduction of > 50%) of the overall severity of acne was observed in 49 patients (98%) on the laser-treated side versus 41 (82%) the control side of the face (P < .05). Hence, we found a significant reduction in the mean percentage of inflammatory papules, pustules, and nodules on the laser-treated versus the control side (79.33 vs 56.92, 78.04 vs 43.33, 64.85 vs 21.93%, respectively) (P < 0.05). Side effects in the form of erythema and irritation during sessions were transient and tolerated by the patients. Conclusion The 577-nm high-power optically pumped semiconductor laser is effective and safe for the treatment of inflammatory lesions (papules, pustules, and nodules) in acne patients.
