Background. Diabetic foot infections (DFIs) are a major public health issue and identification of the microorganisms causing such polymicrobial infections is useful to find out appropriate antibiotic therapy. Meanwhile, many reports have shown antibiotic resistance rising dramatically. In the present study, we sought to determine the prevalence of microorganisms detected on culture in complicated DFIs in hospitalized patients and their antibiotic sensitivity profiles. Methods. A cross-sectional study was conducted for a period of 24 months from 2012 to 2014 in Nemazee Hospital, Shiraz, Iran. The demographic and clinical features of the patients were obtained. Antimicrobial susceptibility testing to different agents was carried out using the disc diffusion method. Results. During this period, 122 aerobic microorganisms were isolated from DFIs. Among Gram-positive and Gram-negative bacteria, Staphylococcus spp. and E. coli were the most frequent organisms isolated, respectively. Of the isolates, 91% were multidrug while 78% of S. aureus isolates were methicillin resistant. 53% of Gram-negative bacteria were positive for extended-spectrum β-lactamase. Conclusion. Given the involvement of different microorganisms and emergence of multidrug resistant strains, clinicians are advised to consider culture before initiation of empirical therapy.

Administrative data from trauma referral centers are useful sources while studying epidemiologic aspects of injuries. We aimed to provide a hospital-based view of injuries in Shiraz considering victims’ age and gender, using administrative data from trauma research center.A cross-sectional registry-based study of adult trauma patients (age ≥15 years) sustaining injury through traffic accidents, violence, and unintentional incidents was conducted. Information was retrieved from 3 hospital administrative databases. Data on demographics, injury mechanisms, injured body regions, and injury descriptions; outcomes of hospitalization; and development of nosocomial infections were recorded. Injury Severity Score (ISS) was calculated by crosswalking from ICD-10 (International Classification of Diseases) injury diagnosis codes to AIS-98 (Abbreviated Injury Scale) severity codes. Patients were compared based on age groups and gender differences.A total of 47,295 trauma patients with a median age of 30 (interquartile range: 24–44 years) were studied, of whom 73.1% were male and the remaining 26.9% were female (M/F = 2.7:1.0). The most common injury mechanisms in the male group were car and motorcycle accidents whereas females were mostly victims of falls and pedestrian accidents (P < .01). As age increased, a shift from transportation-related to unintentionally caused injuries occurred. Overall, young men had their most severe injuries on head, whereas elderly women suffered more severe extremity injuries. Injury severity was similar between men and women; however, elderly had a significantly higher ISS. Although incidence of nosocomial infections was independent of victims’ age and gender, elderly men had a significantly higher mortality rate.Based on administrative data from our trauma center, male gender and age >65 years are associated with increased risk of injury incidence, prolonged hospitalizations, and in-hospital death following trauma. Development of a regional trauma surveillance system may provide further opportunities for studying injuries and evaluating preventive actions.

Liver transplantation is one of the most important therapies for end-stage liver diseases and is associated with major problems including infections and acute rejection. The outcome of transplantation can be determined by immune responses as a key role in response to the graft. Inflammatory and anti-inflammatory mediators especially cytokines influence the graft microenvironment. Th1 and Th2 immune responses in contrast to regulatory responses cause acute rejection or help graft survival. In this study, we evaluated the gene polymorphisms of IL-6 G-174C, TGF-β T + 869C, IL-4 C-590T, and IFN-γ T + 874A cytokines in liver transplant patients. ARMS-PCR method was used to characterize IL-6 G-174C, TGF-β T + 869C and IFN-γ T + 874A polymorphisms and PCR-RFLP using AvaII restriction enzyme was done for IL-4 C-590T characterization in 70 liver transplant patients. Acute rejection episodes were diagnosed according to standard criteria. The analysis of the results showed that IL-6-174 GG genotype ( P = 0.009, OR = 4.333, 95% CI = 1.043-18.000), IL-6-174G allele (P = 0.011, OR = 5.273, 95% CI = 1.454-19.127) was more frequent and IFN-γ +874 TT genotype was less frequent (P = 0.043, OR = 0.143, 95% CI = 0.0118-1.190) in acute rejection than in non-rejection patients. TGF-β T + 869C and IL-4 C-590T frequencies were not significantly different (P > 0.05). According to the results, it can be conclude that IL-6 G-174C and IFN-γ T + 874A gene polymorphisms have predictive values for acute rejection after liver transplantation. High producer genotype of IL-6 is a genetic risk factor and IFN-γ is a protective factor for acute rejection development.

Improving care quality is one of the duties of almost all health service providers. Although it is of much significance to identify the factors influencing nursing care quality in specific clinical settings, a few studies have been conducted to improve our knowledge in this regard. This study aimed to determine Iranian nurses' perceptions of the factors influencing quality of nursing care in general surgery wards. A qualitative approach was adopted using content analysis of semi-structured interviews carried out with 15 nurses working in general surgery wards of two educational hospitals. The following themes and subthemes emerged from the analysis: 'beyond daily routine tasks', 'cooperation and the promotion of effective relationship' and 'updating education'. The second theme consisted of two subthemes: 'relationship among care team members' and 'communication between nurses, patients and relatives'. Providing qualified nursing care in Iran is complicated contextually and is somehow controversial. The study participants believed that in this context, proper delivery of appropriate nursing care is difficult for nurses owing to the barriers mentioned. Therefore, as a primitive action health care policy makers and managers are required to bring sensible changes into health care system through legislating suitable rules to guarantee the quality of nursing cares.

BackgroundEpidemiology of cervical spine fractures (CSfx) in trauma patients of general population is not yet exclusively known.ObjectivesThe purpose of this study was to evaluate the epidemiology of CSfx in trauma patients.Patients and MethodsData from trauma patients admitted in the emergency room (ER) of Shiraz Shahid Rajaei hospital during the 3.5 years period from September 22, 2009 to March 21, 2013, were gathered. All trauma patients with CSfx and/or spinal cord injuries were included in the study. The time of the trauma, mechanism of trauma, injury position, and incidence of cervical spine fractures in the patients were recorded.ResultsA total of 469 patients met the inclusion criteria. The mean age of the patients was 34.7 years old, with a minimum age of 16 years old and a maximum age of 89 years old. Young adults were most frequently affected. Out of 469 cases, 368 patients (78.47%) were male and 101 (21.53%) were female. We had a total of 17 SCI cases among our patients (3.62%), out of which 5 (29.41%) were deceased. The total number of deaths in our study was 29 (6.18%); 5 (17.24%) with SCI and 24 (82.76%) without SCI.ConclusionsThis study demonstrated that most victims of CSfx in our region are 16 to 40 years of age. A male predominance was observed, and motor vehicle collisions were the most frequent trauma mechanism leading to cervical spine injury (mostly due to car rollover accidents), with falls as the second most frequent. The rate of SCI in our study was 3.62% of all cases and the mortality rate was 6.18%.
