RESUMEN
BACKGROUND: A new powder dressing (TPD) is a methacrylate-based powder formulation that transforms in situ into a shape-retentive matrix upon hydration to create optimum moist wound healing conditions. The following randomized, controlled, clinical study aimed to evaluate the role of TPD in the management of chronic venous ulcers (CVU). METHODS: The randomized controlled prospective study enrolled 60 CVU patients. After randomization, patients in the treatment group ( n = 30) were treated with TPD, whereas those in the control group ( n = 30) received conventional compression dressing therapy. RESULTS: After treatment, patients in the TPD group had significantly higher rates of complete ulcer healing at 12 weeks (43.3% vs 10.0%, p = .004) and 24 weeks (86.7% vs 40.0%, p = .001) when compared with conventional dressing group. Moreover, patients in the TP dressing group had significantly shorter time to complete ulcer healing [mean (95% CI): 16.7 (14.1-19.3) versus 37.0 (30.8-43.2) weeks, p = .001]. In addition, patients in the TPD group had significantly fewer number of dressings, less severe pain after dressing, and lower need for systemic analgesics. CONCLUSION: Use of TPD in management of CVUs was associated with significantly higher healing rates, shorter duration to healing, and lower pain.

Repairing bilateral cleft lip (BCL) with a modified Z-Plasty technique to overcome many complications encountered with other traditional techniques was attempted in a group of Egyptian subjects at the Department of Oral and Maxillofacial Surgery, Faculty of Medicine for Girls, Al Azhar University, Cairo, Egypt between May 2018 to May 2021. The study included 20 patients suffering from primary BCL of both genders with ages ranging from one week to one year. 60% of the patients were female and 40% were males. The modified Z-Plasty technique was used in all patients. Wound healing in all cases was uneventful. No inflammation, infection or wound dehiscence were reported in this study. Postoperative gummy show improved significantly (p=0.001), and 70% of patients had zero postoperative maxillary ridge show as lip lengths improved significantly. The clinical results of the modified double Z-Plasty technique used for closure of BCL were very interesting and avoid scarifying vermillion tissue in addition to the increase of both philtrum length and lip volume. Key Words: Bilateral cleft left lip, Repair, Z-Plasty.

PURPOSE: There is still no definitive consensus about the ideal technique in the treatment of anterior mandibular fractures. Therefore, this study aimed to determine clinical and radiographic outcomes of four different internal fixation devices used for this type of fractures. METHODS: This was a cohort study that included 64 fracture cases. Fractures were fixed using four types of open reduction internal fixation devices: single 2.0-mm mini-locking plates, double 2.0-mm miniplates, double lag screw and double microplates. Investigated variables were surgical duration, wound dehiscence, infection, occlusion, mouth opening, patient compliance, nerve damage and postoperative oedema. RESULTS: Male patients constituted 90.6% of the study sample. A proportion of 33% of the fractures were single symphysis and 67% were parasymphysis fractures. The most time-saving technique was the lag screw followed by microplate with mean/SD of 50.65 ± 4.152 min. Wound dehiscence occurred in 4.7% and 3.1% of the miniplate and the mini-locking groups respectively. Miniplate and microplate groups had small interfragmentary space at 1-month postoperative radiographs, while mini-locking and lag screw groups had no extra-callus formation. CONCLUSION: The double lag screw and the single mini-locking plate are the most effective devices for primary bone healing of displaced mandibular symphysis/parasymphysis fractures which is attributed to their enhanced stability. Miniplates and microplates gave functionally well-balanced fixation and were also associated with higher patient convenience due to improved adaptability and relatively lower cost than locking plates. Cost-effectiveness of lag screws in comparison to bone plates is particularly beneficial in low-income countries.
