Title: Otoplasty: New Modification of the Mustardé technique
Author: Mohamed A.S.M. El-Rouby, MD,
Assistant Professor of Plastic surgery, Ain Shams University, Cairo, Egypt.
Abstract
Background: one of the most established techniques for management of protruding ears is the Mustardé technique (1). Many modifications had been published for this technique; however, all these modifications started by retro-auricular incision. We modify the Mustardé technique using three retroauricular microincisions to correct several deformities of the auricular cartilage in protruding ears.
Patients and Methods: 46 patients (7unilateral, 39 bilateral) (85 ears) who were candidates for this technique, their age (25 ± 2.8 years), 38 males, 8 females. The operation time, steps, follow up sessions (2 weeks, 3, 6 and 18 months) data was recorded. Preoperative and postoperative (1,18 months) photos were compared and analyzed by custom made computer program the evaluated the results.
Results: 42 patients achieve a natural appearance. extrusion of threads occurred in 8 ears. Asymmetrical ears were noticed in 4 patients and recurrence in 11 patients. These patients were revised by Mustardé technique with retro-auricular incisions. None of the patients developed retro-auricular scars.
Conclusion: this versatile modification allows for better asthenic results of otoplasty and minimizes complications of skin incision unless cartilage and/or skin resection is needed.
This study compared the efficacy of injectable collagenase versus partial fasciectomy in treating Dupuytren's contracture. 15 patients (33 rays) were divided into two groups: Group A underwent partial fasciectomy (26 rays) while Group B was treated with collagenase injections (7 rays). The collagenase treatment was found to be safe and effective, with contractures improving significantly and few complications. However, recurrence and failure rates were slightly higher compared to surgery. While collagenase injection is a good alternative to surgery, its higher cost should be considered, especially in developing countries.
This document provides information about Mohamed Ahmed El-Rouby, an assistant professor of plastic and reconstructive surgery, and summarizes his expertise in wound closure techniques. It discusses direct closure for linear wounds, skin grafts or flaps for wide area wounds and skin loss, and re-implantation for amputations. Skin grafts are described as tissue transferred without its own blood supply, while flaps have an intact vascular supply. Factors like thickness, origin, adherence and revascularization processes are reviewed for grafts. Complications and various applications of grafts and flaps for nerves, fat, tendons, cartilage, bone and more are outlined.
Gangrene is the death of body tissue due to loss of blood supply. It is caused by infection or reduced blood flow and can be dry, wet, or gas gangrene. Dry gangrene develops slowly in tissues like the feet of diabetics. Wet gangrene occurs rapidly in moist tissues and causes swelling and odor. Gas gangrene is a medical emergency caused by soil bacteria that produce tissue-damaging gases. Treatment involves antibiotics, surgery to remove dead tissue, and sometimes amputation.
This document discusses reconstruction of eyelid defects. It begins by describing the anatomy and functions of the eyelids. Eyelid defects can be anatomical, involving the structure of the eyelid, or functional, affecting eyelid movement. The objectives of reconstruction are to restore anatomical integrity, physiological function, and acceptable cosmetic appearance. Various surgical techniques are described for reconstructing different types and sizes of defects in the upper and lower eyelids. Key principles include documenting the defect, avoiding tension, and using similar tissue when possible. The timing, planning and postoperative care of reconstruction are also outlined.
This document provides information on various topics related to wound management and suturing techniques. It begins with an introduction and contact information for Dr. Mohamed Ahmed El-Rouby. It then covers topics such as sterilization, wound classification, tetanus prophylaxis, wound healing, closure techniques, suture materials and types, and various suturing methods. Diagrams are provided to illustrate different suture patterns. The document aims to be a comprehensive reference on wound management and suturing.

Liposuction causes an increase in coagulative factors in the treated area, helping to stop bleeding and allowing for minimal bleeding in additional surgery. Liposuction also leaves connections between skin and fascia intact, which is why sensation in the region is much less affected than with surgical excision that severs those connections.

This document discusses bone structure, types, healing, and grafting. It describes that bone is composed of cells integrated into a rigid calcium framework. There are two main types of ossification - endochondral, where bone forms within cartilage templates in long bones, and membranous, where bone forms directly in flat bones. Fracture healing can occur directly through bony reconstruction or indirectly through soft and hard callus formation. Bone grafts are used for nonunions, defects, and augmentation, and work through osteogenesis, osteoinduction and osteoconduction. Autogenous grafts from sites like the iliac crest are commonly used but allografts and substitutes like BMP are also options.
Burn injuries do not just cause local skin damage, but impair the function of many organs and systems through the release of inflammatory mediators into the bloodstream. Haemofiltration is a renal replacement therapy that can remove these inflammatory mediators, as well as urea, creatinine, and toxins from patients with severe burns. Indications for its use include renal failure, sepsis, respiratory distress syndrome, and refractory electrolyte imbalances or fever. The document evaluates the efficacy of haemofiltration in removing inflammatory mediators of varying molecular weights and its role in treating systemic inflammatory response syndrome in burned patients.
This document provides an overview of systemic inflammatory response syndrome (SIRS) authored by Professor Dr. Mohamed El Rouby. It defines SIRS as a severe systemic response to a critical incidence characterized by disseminated immune activation and capillary dysfunction, which can result in organ dysfunction. The pathophysiology of SIRS involves the release of lipopolysaccharides and lipid-protein complexes from infected or burned tissues, triggering cytokine cascades and immune responses that can lead to multiple organ dysfunction syndrome if not controlled. Treatment focuses on eliminating triggers through antibiotics, wound excision, and supporting organ functions through ventilation, fluids, and inotropes.
Renal failure is a major systemic complication that can occur after severe burns. The kidneys play important roles in excretion, regulation, and endocrine functions that are disrupted in renal failure. Acute renal failure occurs most commonly due to hypovolemia, massive dead tissue, sepsis, or hypercatabolic states. It is important to provide adequate fluid resuscitation to prevent renal failure. If it occurs, management involves clinical nutrition, renal replacement therapies like hemodialysis or hemofiltration, and treating underlying issues.
Rhytidectomy, also known as a face lift, has evolved over time from early procedures that were viewed negatively to becoming more accepted. The classic facelift technique developed in the 1950s, while newer deep plane techniques emerged in the 1990s. A thorough preoperative evaluation assesses medical history, expectations, and identifies asymmetries to plan the optimal procedure. The surgery involves incisions and redistribution of the superficial musculoaponeurotic system to improve contours, while minimizing risks like hematoma and nerve injury.
- Burn injuries occur when skin comes into contact with heat, chemicals, electricity or radiation. The severity depends on the intensity and duration of exposure.
- Most burns occur in the home, especially for young children and the elderly, and are often caused by cooking or hot liquids. For teenagers, burns sometimes result from suicide attempts.
- Burn management involves three phases: emergent, acute, and rehabilitative. In the emergent phase, risks include shock, respiratory complications, and kidney problems, so large burns require fluid resuscitation, airway management, and wound care. Proper treatment helps prevent infection and scarring. Referral to a burn center is advised for severe or complicated burns.

8 Surprising Reasons To Meditate 40 Minutes A Day That Can Change Your Life.pptxHolistified Wellness
We’re talking about Vedic Meditation, a form of meditation that has been around for at least 5,000 years. Back then, the people who lived in the Indus Valley, now known as India and Pakistan, practised meditation as a fundamental part of daily life. This knowledge that has given us yoga and Ayurveda, was known as Veda, hence the name Vedic. And though there are some written records, the practice has been passed down verbally from generation to generation.

Cell Therapy Expansion and Challenges in Autoimmune DiseaseHealth Advances
There is increasing confidence that cell therapies will soon play a role in the treatment of autoimmune disorders, but the extent of this impact remains to be seen. Early readouts on autologous CAR-Ts in lupus are encouraging, but manufacturing and cost limitations are likely to restrict access to highly refractory patients. Allogeneic CAR-Ts have the potential to broaden access to earlier lines of treatment due to their inherent cost benefits, however they will need to demonstrate comparable or improved efficacy to established modalities.
In addition to infrastructure and capacity constraints, CAR-Ts face a very different risk-benefit dynamic in autoimmune compared to oncology, highlighting the need for tolerable therapies with low adverse event risk. CAR-NK and Treg-based therapies are also being developed in certain autoimmune disorders and may demonstrate favorable safety profiles. Several novel non-cell therapies such as bispecific antibodies, nanobodies, and RNAi drugs, may also offer future alternative competitive solutions with variable value propositions.
Widespread adoption of cell therapies will not only require strong efficacy and safety data, but also adapted pricing and access strategies. At oncology-based price points, CAR-Ts are unlikely to achieve broad market access in autoimmune disorders, with eligible patient populations that are potentially orders of magnitude greater than the number of currently addressable cancer patients. Developers have made strides towards reducing cell therapy COGS while improving manufacturing efficiency, but payors will inevitably restrict access until more sustainable pricing is achieved.
Despite these headwinds, industry leaders and investors remain confident that cell therapies are poised to address significant unmet need in patients suffering from autoimmune disorders. However, the extent of this impact on the treatment landscape remains to be seen, as the industry rapidly approaches an inflection point.

ABDOMINAL TRAUMA in pediatrics part one.drhasanrajab
Abdominal trauma in pediatrics refers to injuries or damage to the abdominal organs in children. It can occur due to various causes such as falls, motor vehicle accidents, sports-related injuries, and physical abuse. Children are more vulnerable to abdominal trauma due to their unique anatomical and physiological characteristics. Signs and symptoms include abdominal pain, tenderness, distension, vomiting, and signs of shock. Diagnosis involves physical examination, imaging studies, and laboratory tests. Management depends on the severity and may involve conservative treatment or surgical intervention. Prevention is crucial in reducing the incidence of abdominal trauma in children.
