Suction tube facilitates the transfer of nasal tip sutures in endonasal rhinoplasty

Nasal tip sculpturing is the most challenging aspect of rhinoplasty. It is principally performed by the reduction or increment of the nasal tip characteristics with sutures or grafts using endonasal or external approach. In endonasal approach, although most of the key structural mechanisms of the nasal tip can be preserved, the transfer of nasal tip sutures, which are used for contouring the alar cartilages and/or graft stabilization, from 1 nasal cavity to another has several difficulties such as time loss, need for extensive dissection, or injuring the soft tissue and alar cartilages. In the current article, we aimed to represent our surgical technique that facilitates suture contouring using a suction tube during the transfer of nasal tip sutures in endonasal rhinoplasty.     

β-Glucan treatment prevents progressive burn ischaemia in the zone of stasis and improves burn healing: An experimental study in rats

Saving the zone of stasis is one of the major goals of burn specialists. Increasing the tissue tolerance to ischaemia and inhibiting inflammation have been proposed to enable salvage of this zone. After a burn, excessive inflammation, including increased vascular permeability, local tissue oedema and neutrophil activation, causes local tissue damage by triggering vascular thrombosis and blocking capillaries, resulting in tissue ischaemia and necrosis. Oxygen radicals also contribute to tissue damage after a burn. However, macrophages play a pivotal role in the response to burn. We studied β-glucan because of its many positive systemic effects that are beneficial to burn healing, including immunomodulatory effects, antioxidant effects (free-radical scavenging activity) and effects associated with the reduction of the inflammatory response.     

Solitary bone metastasis in the tibia as a presenting sign of endometrial adenocarcinoma: a case report and the review of the literature

Background Metastasis to bone from endometrial adenocarcinoma is rare, when metastasises it usually locates in axial skeleton. Metastasis to extremities is extremely rare. Additionally the detection of the bone metastasis as a presenting feature is uncommon. In the present study we report the 10th cases of bone metastasis in the literature which located at tibial diaphysis and originated from endometrial adenocarcinoma as a presenting feature of the primary disease. Case Single tibial lesion was observed in a 70 years old woman. Biopsy confirmed metastatic adenocarcinoma of the unknown origin. We couldn’t find the primary origin with aggressive work-up. Tibial lesion regressed with radiotherapy. Endometrial adenocarcinoma is detected after the end of disease-free one year with the symptom of vaginal bleeding. After 47 months from initial tibial lesion and 35 months from gynaecologic operation, patient is still alive and disease free. Discussion Patients with endometrial adenocarcinoma presenting an isolated skeletal metastasis may exhibit an unusual group with a better prognosis. This study was presented as a poster exhibition at the 5th Meeting of Asia-Pasific Musculo Skeletal Tumour Society held between 23 and 25, April 2004, Izmir, Turkey.     

Effects of vitamin K in postmenopausal women: Mini review

Possible benefits of vitamin K on bone health, fracture risk, markers of bone formation and resorption, cardiovascular health, and cancer risk in postmenopausal women have been investigated for over three decades; yet there is no clear evidence-based universal recommendation for its use.     

Epidemiology of COVID-19: What changed in one year?

A coronavirus brought the first pandemic attack of this century as a flu virus did a hundred years ago. This greatest pandemic of the century brings us new opportunities to understand and explore the dynamics of a contagious disease. Nearly two years later, we are still collecting the evidence to understand the disease. Some basic epidemiological properties are still urgently needed. Not only the origin of the virus but also Ro value, possible transmission routes, epidemiologic curves, case fatality rates, seasonality, severity and mortality risk factor, effects on the risk groups, differences between countries and so on still require strong evidence prior to making final suggestions. In this review, we tried to evaluate the epidemiological evidence to scrutinize where exactly we are in this pandemic.
