Clinical and epidemiologic evaluation of pressure ulcers in patients at a university hospital in Turkey.

OBJECTIVE: We sought to measure the incidence of pressure ulcer development at a university health center in Turkey, and to determine whether the Waterlow Pressure Sore Risk (PSR) Scale score predicted pressure ulcer development, stage, or number of ulcers. DESIGN: We prospectively evaluated patients who were hospitalized at our university-based medical center. SETTING AND SUBJECTS: We analyzed data from 22,834 patients hospitalized at the Baskent University Adana Teaching and Medical Research Center in Ankara, Turkey from January 1, 2004 to December 31, 2004, including 360 patients who developed pressure ulcers. INSTRUMENTS: The Waterlow PSR Scale was used to assess pressure ulcer risk. In addition, age, sex, the ward or unit in which the patient was hospitalized, reason for hospitalization, and location and stage of ulcers were collected on a data form designed specifically for this study. METHODS: A single nurse physiotherapist assessed all patients daily during their hospitalization. When a pressure ulcer was diagnosed by the nurse physiotherapist, a physician staged the pressure ulcers based on the US National Pressure Ulcer Advisory Panel (NPUAP) staging system. RESULTS: Three hundred sixty out of 22,834 patients developed 1 or more pressure ulcers, resulting in an incidence rate of 1.6%. Most ulcers (59.2%) occurred in patients hospitalized in the intensive care unit (n = 213). A positive correlation between the Waterlow PSR Scale score and number of ulcers per patient (r: 0.178, P < .01) was identified. No significant correlation was found linking Waterlow PSR Scale score and ulcer stage or the development of a single ulcer. CONCLUSION: We found significantly lower pressure ulcer incidence rates than those commonly reported in the literature, which we believe is principally attributable to short hospital stays and a strong emphasis on preventive nursing care. While high Waterlow PSR scale Scores correlated positively with development of multiple ulcers, this did not predict ulcer stage or the presence of a single pressure ulcer.     

Subcutaneous cryptococcosis due to Cryptococcus diffluens in a patient with sporotrichoid lesions case report, features of the case isolate and in vitro antifungal susceptibilities.

Environmental fungi, in particular primary pathogens and Cryptococcus spp. can be responsible for skin lesions mimicking sporotrichosis. In this paper, we report a case of subcutaneous cryptococcosis in an apparently healthy, young male patient due to a non-C. neoformans Cryptococcus species, C. diffluens. The isolate showed in vitro phenotypic switching that may affect virulence and host inflammatory and immune responses, and in vitro resistance to amphotericin B and 5-flucytosin. This species shares several phenotypic traits with C. neoformans, and, therefore, decisive diagnosis should be based on biopsy and culturing results followed by molecular identification.     

Factor V gene (1691A and 4070G) and prothrombin gene 20210A mutations in patients with Behçet's disease

OBJECTIVES: Beh?et's disease (BD) is a chronic inflammatory disorder of still unknown etiology, characterized by endothelial cell injury/dysfunction and thrombosis and/or aneurysm of large blood vessels. Thrombophilia may play a role in the pathogenesis of thrombosis in BD. The common inherited gene defects, factor V (FV) 1691A (Leiden) and prothrombin (PT) 20210A, are known risk factors for thrombosis. The FV 4070G polymorphism was shown to influence circulating FV levels and to contribute to the activated protein C resistance phenotype. The aim of the study was to evaluate the role of FV 1691A, FV 4070G and PT 20210A gene mutations in Turkish BD patients with and without venous thrombosis. METHODS: Seventy-one patients with BD (27 with venous thrombosis) and 91 healthy subjects were included in the study. FV 1691A, FV 4070G, and PT 20210A mutations were determined by a method based on PCR-RFLP. RESULTS: The frequency of FV 1691A heterozygous mutation in BD patients with venous thrombosis (25.9%) was significantly higher than that in healthy subjects (8.8%; OR = 3.63; 95% CI 1.18-11.2). Although the frequency of this mutation in patients with venous thrombosis was higher than that in the patients without venous thrombosis (11.4%), the difference did not reach a statistically significant level (OR = 2.73; 95% CI 0.77-9.70). In BD patients with thrombosis, the frequencies of FV 4070G and PT 20210A were not significantly different compared to the BD patients without venous thrombosis and healthy subjects. CONCLUSIONS: Our results suggest that the FV 1691A, FV 4070G, and PT 20210A mutations are unlikely to play an important role in the pathogenesis of thrombosis in patients with BD.

The effect of socioeconomic factors on quality of life after treatment in patients with head and neck cancer

PURPOSE: To determine the effect of socioeconomic factors on quality of life (QoL) after treatment in patients with head and neck carcinoma (HNC). PATIENTS AND METHODS: The study population included 50 HNC patients seen in their control examinations after radiotherapy during a 2-month interval and who were willing to complete the Short-Form 36 QoL questionnaire. Socioeconomic, demographic, and tumor- and treatment-related factors were analyzed for their effect on physical component summary score (PCS) and mental component summary score (MCS) using the Mann-Whitney U test. RESULTS: All patients received radiotherapy, and 33 patients (66%) underwent surgery for the primary tumor and/or neck disease. Chemotherapy was given in 9 patients (18%). Mean PCS and MCS were 47.9 (range, 24.8-59.3) and 46.7 (range, 22-63.3) for the whole patient population. There was no significant factor affecting PCS. Education level of "middle school or higher," perceived economic status of "medium or higher," social security status of not being "absent or minimally covered," and unilateral type of neck surgery were found to increase MCS significantly. According to separate linear regression analyses performed for three socioeconomic variables, the most significant factor for MCS was social security status compared with education level and perceived economic status. It was the only parameter that retained its significance when all five parameters were combined in a linear regression model. CONCLUSION: This study demonstrated that educational status, perceived economic status, and social security status showed a significant effect on the QoL of HNC patients after radiotherapy. When all variables were taken into account, only "social security status" remained significant.     

Major limb amputation and mortality in patients with neuro‐ischaemic lower extremity wounds managed in a tertiary hospital: Focus on the differences among patients with diabetes,peripheral arterial disease and both

A majority of lower extremities neuro‐ischaemic wounds (NIU) are related to: (a) only diabetes (DM); (b) only peripheral artery disease (PAD); (c) co‐existing diabetes and peripheral artery disease (DM‐PAD). This study aims to characterise the major clinical outcomes of forementioned three groups of lower extremity wound patients in Singapore. Patients hospitalised for lower extremity NIU between January 2014 and October 2017 in a tertiary hospital in Singapore were analysed. Patients'' major limb amputation and mortality were assessed using Cox regression models. Cumulative survival and amputation‐free survival among the three classified groups were calculated using Kaplan‐Meier analysis. Compared with patients with only DM, those in the PAD group and the DM‐PAD group had higher risk of major limb amputation (adjusted hazard ratio: 2.47, 95% CI: 1.65‐3.70; adjusted hazard ratio: 2.01, 95% CI: 1.53‐2.65 respectively) and mortality (adjusted hazard ratio: 2.36, 95% CI: 1.57‐3.55; adjusted hazard ratio: 2.46, 95% CI: 1.86‐3.26 respectively). The 3‐year survival and amputation‐free survival were lowest in the DM‐PAD group (52.1% and 41.5% respectively), followed by the PAD group (53.3% and 44.6% respectively) and the DM group (74.2% and 68.5% respectively). Lower extremity NIU patients with PAD or DM‐PAD were found to have poorer clinical prognosis than those with DM only.
