    ABSTRACT OBJECTIVES: Diabetes mellitus is one of the most important independent risk factor for poor outcomes in patients with burn injuries. In this study, we aimed to determine the demographics characteristics, clinical presentation, and outcomes of burn patients with preexisting diabetes mellitus seen over the previous 5 years at a single burn center. MATERIALS AND METHODS: We conducted a retrospective study that included all burn patients ≥18 years of age with a diagnosis of diabetes who were admitted to our unit over the previous 5 years (2018 to 2022). We collected demographics and relevant clinical data from medical records. Patients were evaluated by age subgroups and time interval between occurrence of injury and admission to a medical center. RESULTS: Our study included 52 patients, with male-to-female ratio of 0.86:1 and mean age of 62.7 ± 12.4 years (range, 33-85 y). Scalding was the most common cause of the burn injury. A total of 32.7% of the patients had burns affecting their hands, either as part of a more extensive burn or as an isolated injury. The median extent of burns was 1.0% total body surface area (range, 0.05%-10%). We found an association between age and burn etiology and age and burn site. A high number of patients with injuries in the lower extremity sought medical care after day 1 but before day 4 postinjury. Delayed admission was found to be an important factor causing an increase in complication frequency. CONCLUSIONS: There are many factors associated with age that affect the incidence and outcomes of burn injuries. Risk factors leading to burns are preventable, and the physical and psychological consequences of people who survive burn injuries can be life-threatening and often devastating. The best way to treat a burn is to prevent it from happening in the first place.

    Effects of a Fat-Rich Diet in the Pancreas of Rats During the Acute Phase of Burns
    (Başkent Üniversitesi, 2022-06) Neslihan Başçıl Tütüncü; Ayse Ebru Abali; Santiago J. Santelis; Özlem Turhan İyidir; B. Handan Ozdemir; Gonca Ozgun; Nilüfer Bayraktar; Meriç Çolak; Mehmet Haberal
    ABSTRACT OBJECTIVES: Oversupply of nutrients overstimulates beta cells in standard conditions, and severe burn injuries increase the metabolic needs. In this study, we investigated the effects of fat-rich nutrients on the endocrine pancreas during the acute phase of severe burns.

    Impact of Severe Burns on Pancreatic Islets: An Experimental Model in Rats
    (Başkent Üniversitesi, 2022-03) Santiago J. Santelis; Ayse Ebru Abali; Gonca Ozgun; B. Handan Ozdemir; Neslihan Basci Tutuncu; Mehmet Haberal
    ABSTRACT OBJECTIVES: Severe burn victims experience a systemic inflammatory response and a hypermetabolic response that can generate adverse effects on many distant organs and systems. Our aim in this study was to describe the histopathological changes in the pancreatic islets secondary to severe burns in an experimental animal model. MATERIALS & METHODS: Fourteen Wistar albino rats were randomly divided into 2 groups: the sham group and the burn group. A full-thickness burn model was designed to induce a burn of 25% total body surface area. Seven days after burn induction and sham procedure, pancreatectomy was performed. Pancreatic tissues were examined under light microscopy, and islet size and cellularity were calculated. RESULTS: The histopathologic examination was unremarkable, but the mean number of islets per pancreatic tissue was lower in the burn group than in the sham group. We observed a significant difference in the mean number of cells per one islet between the 2 groups, with the cell count higher in the burn group (P < .05). CONCLUSIONS: During the acute phase of burn injury in rats, we observed a decrease in the number of pancreatic islets with remarkable hypercellularity. Further studies are needed to determine the histological and cellular basis of these changes.
