BACKGROUND: There has been little investigation regarding air quality and rhinitis in the pathophysiology of upper airway disease. In this study, we assessed the impact of inhalant pollutants (particulate matter 2.5 [PM2.5 ] and black carbon [BC]) on allergic rhinitis and chronic rhinosinusitis (CRS) disease severity. METHODS: CRS patients with nasal polyps (CRSwNP) and without polyps (CRSsNP) were identified. Spatial modeling from pollutant monitoring sites was used to estimate exposures for patients meeting the inclusion criteria (total, n = 125; CRSsNP, n = 67; CRSsNP, n = 58)...

Skin tightening is one of the cornerstones of skin rejuvenation and is defined as the improvement of skin laxity and crepiness of the skin. There are several energy-based devices that can produce significant skin tightening without surgery, both on and off the face. The mechanisms of skin tightening involve collagen denaturation resulting in collagen shrinkage and tissue tightening, and the wound healing response that generates new collagen and elastin. These hypothesized mechanisms of skin contraction leading to clinical skin tightening have been derived from histological, immunohistochemical, and electron microscope analysis, as well as in vitro and in vivo experiments...

#10
Rajinder Parshad, ᅟ Suhani
Port placement is the first and one of the most important step in laparoscopic surgeries. However, these incisions for port placement are often placed casually leading to larger or smaller incisions than those required. Larger incisions may lead to problems like oozing from skin incisions, egress of gas used to create pneuomoperitoneum, while smaller incisions lead to difficulty in port introduction and incision site skin necrosis. We describe a simple and novel technique of giving proper sized skin incision to avoid such problems...

Although pulmonary function was better after video-assisted thoracoscopic surgery (VATS) lobectomy than after open thoracotomy lobectomy, it is unclear whether postoperative pulmonary function after VATS lobectomy is better than that after mini-thoracotomy lobectomy. The aim of this study is to determine whether the former is better than the latter. VATS lobectomies were performed using endoscopic techniques through a 3-4-cm skin incision spread by a silicon rubber retractor and two or three trocars. Mini-thoracotomy lobectomies were performed through a 7-12-cm skin incision spread by rib retractors made of metal and one or two trocars...

Background: Since its inception, reduction mammoplasty has matured considerably. Primary evolution in clinical research and practice initially focused on developing techniques to preserve tissue viability; breast parenchyma, skin, and nipple tissue that has expanded to include sensation and erectile function play a large role in the physical intimacy of women. Studies regarding primary innervation to the nipple are few and often contradictory. Our past anatomical study demonstrated that primary innervation to the nipple to come from the lateral branch of the fourth intercostal nerve...

Adipose-derived mesenchymal stem cells (ASCs) have immunoregulatory properties, but their activity is dependent on signals provided by the local microenvironment. It is likely that highly inflammatory milieu of rheumatoid joint affects ASCs activity. To test this hypothesis, the function of rheumatoid ASCs derived from articular adipose tissue (AT-ASCs) and ASCs derived from subcutaneous adipose tissue (Sc-ASCs) has been analysed. Articular adipose tissue (infrapatellar fat pad) and subcutaneous adipose tissue (from the site of skin closure with sutures) were obtained from rheumatoid arthritis (RA) patients undergoing total knee joint replacement surgery...

BACKGROUND: Clean intermittent catheterization (CIC) is a standard treatment for patients who are unable to empty the bladder. In the absence of the urethra or if catheterization through the urethra is problematic, a continent vesicostomy is used as a catheterizable conduit. The Malone procedure is an established treatment option for children with neurogenic constipation and fecal incontinence. OBJECTIVES: The aim of the study was to report the authors' experience with continent catheterizable conduits (CCCs) in children, to review the results and to determine the efficacy of the technique, with an emphasis on continence and the need for revision...

Kristian M Hargadon
Melanoma is a highly aggressive form of skin cancer that frequently metastasizes to vital organs, where it is often difficult to treat with traditional therapies such as surgery and radiation. In such cases of metastatic disease, immunotherapy has emerged in recent years as an exciting treatment option for melanoma patients. Despite unprecedented successes with immune therapy in the clinic, many patients still experience disease relapse, and others fail to respond at all, thus highlighting the need to better understand factors that influence the efficacy of antitumor immune responses...
