Pottery is one of the artistic-technical craft that has persisted for several millennia from prehistoric times to the present day. Such artifacts, particularly in Iran, exhibit high stylistic and technological diversity. In most archaeological excavations, consistently various types of these artifacts from different historical periods and styles have been discovered, whose technical study and form recovery can provide valuable information to researchers in various fields. Among these excavations is the Tappeh-Silveh in Piranshahr, where diverse pottery dating back to the Chalcolithic, Early Bronze Age, Iron Age, as well as remnants from the Parthian period and the subsequent Islamic period have been uncovered. The specimen studied in this article is a decorated orange pottery piece with black and red colors and geometric patterns, belonging to the Bronze Age from this site. This piece has sustained damages such as fractures, losses, and deposits, , which have been improperly repaired. It requires cleaning, reattachment, and reconstruction of the missing parts, while adhering to the theoretical principles of conservation. Accordingly, after necessary pathological and technical studies of the artifact using laboratory methods, an appropriate cleaning method was selected, and essential actions were taken towards its protection and restoration.

Wound management of trauma patients is one of the most important and common measures in the emergency department. Following trauma, hemodynamic and metabolic changes occur in the body that are sometimes very complex and lead to many complications and deaths, even with great care. The aim of this study was to investigate the risk factors for managed wounds in trauma patients referred to the emergency department of Imam Khomeini Hospital in Urmia.

This descriptive-analytical study was performed on all trauma patients referred to the emergency department of Imam Khomeini Hospital in Urmia from October 1, 2017 to March 20, 2017 by census. Data were collected using a checklist that includes demographic characteristics, underlying diseases, wound characteristics and wound management of patients in terms of complications and recovery in the sixth month according to the Vancouver Oscar criteria.

Of 350 patients studied, 86 (24.6%) were female and 264 (75.4%) were male and the mean age of patients was 37.3±11.1 years. The most common complications were infection (9%) and inflammation around the wound (5%). Smoking (P<0.05), diabetes (P = 0.03) and wound infection (P = 0.03) were associated with infection, Antibiotic prophylaxis (P=0.02) and keeping the wound clean were also associated with a reduced incidence of infection (P=0.01). The mean degree of wound was 6.4 ± 2.3 at the beginning of admission for patients and 3.1±1.6 after 6 months; Statistical evaluation showed that there was a significant decrease in the degree of wounds after 6 months (P=0.001).

Diabetes and smoking are common risk factors for infection and reduced wound healing.
