Tissue changes around dental implants installed in alveolar ridge preservation sites: A 1-year follow-up randomized controlled clinical trial.

Objective: This study aimed to assess radiographic marginal bone changes 22 months post extraction, which is 1 year after implant loading in alveolar ridge preservation (ARP) sites grafted with a combination of collagen-embedded xenogenic bone substitute (DBBM-C) and collagen matrix (CMX), comparing them with implants placed in naturally healed sites.

Methods: This randomized controlled clinical trial was conducted over 22 months. Patients who needed a single tooth extraction and subsequent implant placement in nonmolar areas were enrolled.

Hard to heal pressure ulcers (stage III-IV): efficacy of injected activated macrophage suspension (AMS) as compared with standard of care (SOC) treatment controlled trial.

The objective of this study was to compare local injections of AMS with SOC treatments for stage III and IV pressure ulcers in elderly patients. It was designed as historically prospective 2-arms non-parallel open controlled trial, and conducted in a department of geriatric medicine and rehabilitation of a university affiliated tertiary hospital. We studied 100 consecutive elderly patients with a total of 216 stage III or IV pressure ulcers, 66 patients were assigned to the AMS group and had their wounds injected, while 38 patients were assigned to the SOC group.

Expanded reverse abdominoplasty for reconstruction of burns in the epigastric region and the inframammary fold in female patients.

We report the use of expanded reverse abdominoplasty in three female patients with postburn scars involving the entire epigastric region in which the inframammary folds were effaced, resulting in distortion of breast contour. In two of the patients, tissue expanders were used, and subsequently, reverse abdominoplasty was performed, thus re-creating the inframammary fold. The third patient reported to be pregnant after expanders were placed; therefore, smaller volumes of inflation for tissue expansion were necessary.

Epidermoid inclusion cysts After APTOS thread insertion: case report with clinicopathologic correlates.

The APTOS threading procedure is a relatively new method in antifacial ptosis surgery. The reported cases present a small percentage of minor complications. A 57-year-old woman experienced scarring after APTOS threading.

Stensen duct rupture (sialocele) and other complications of the Aptos thread technique.

Background: The Aptos thread technique is a mode of uplifting the flabby soft tissue of the aging face. Permanent suture material made of polypropylene monofilament with dents is used in this technique. This procedure is gaining popularity throughout the world.

Nitrous oxide administered by the plastic surgeon for repair of facial lacerations in children in the emergency room.

Background: The purpose of this study was to investigate a means of providing pain relief during repair of facial lacerations in children in the emergency room.

Methods: This study was conducted in the emergency room of a tertiary care, university-affiliated hospital. Fifty percent nitrous oxide was administered by the surgeon who sutured the laceration.

Necrotizing periorbital cellulitis following aesthetic rhinoplasty.

Rhinoplasty is rarely complicated with infection. We present a case of necrotizing periorbital cellulitis that developed in an 18-year-old woman following aesthetic rhinoplasty. The clinical manifestations consisted of swelling of the eyelids and necrosis of the lower eyelid regions, accompanied by high fever.

Genetics in melanoma.

Melanoma is the leading cause of death from skin tumors worldwide, with an annual increase in incidence over the past decade. The molecular mechanisms involved in melanoma pathogenesis are beginning to be unraveled. While a family history of melanoma and exposure to ultraviolet irradiation have been known for years as risk factors in melanoma development, the precise genes involved in inherited predisposition were defined only in the past decade.

[Silicone breast implants with silicone gel and autoimmune disease--are they related?].

Silicone breast implants are used for breast reconstruction and breast augmentation. In the late 80's anecdotal literature describing a possible connection between silicone gel filled breast implants and autoimmune disease accumulated. Emerging concern about the safety of silicone gel implants had led the FDA to restrict their use.
