Risk factors for high fall risk in elderly patients with chronic kidney disease

International Urology and Nephrology - Patients with chronic kidney disease (CKD) usually represent an aging population, and both older age and CKD are associated with a higher risk of falling....     

Development and psychometric evaluation of the patient knowledge of,and attitudes and behaviours towards pressure ulcer prevention instrument (KPUP)

The Patient Knowledge of, and Attitude and Behaviour towards Pressure Ulcer Prevention Instrument (KPUP) was developed and validated using a two‐stage prospective psychometric instrument validation study design. In Stage 1, the instrument was designed, and it is psychometrically evaluated in Stage 2. To establish content validity, two expert panels independently reviewed each item for appropriateness and relevance. Psychometric evaluation included construct validity and stability testing of the instrument. The questionnaire was administered to a convenience sample of 200 people aged more than 65 years, living independently in the community; reliability and stability were assessed by test/retest procedures, with a 1‐week interval. Mean knowledge scores at ‘test’ were 11.54/20 (95% CI = 11.10‐11.99, SD: 3.07), and ‘retest’ was 12.24 (95% CI = 11.81‐12.66, SD: 2.93). For knowledge, correlation between the test/retest score was positive (r=. 60), attitude section‐inter‐item correlations ranged from r = −.31 to r = .57 (mean intraclass correlation coefficient of r = .42), and internal consistency for the retest was the same as the test (α = .41 for the eight items). For health behaviours, individual inter‐item correlations for test items ranged from r = −.21 to r = .41 for the 13 standardised items. Psychometric testing of the KPUP in a sample of older persons in the community provided moderate internal consistency and general high test‐retest stability.     

A case of septal panniculitis secondary to interferon treatment

The most common side effects of interferon-beta therapy following subcutaneous administration include pain, inflammation and induration at the injection site, which occur in approximately 20–60% of patients. Besides, transient injection-site erythema is frequently seen in beta-interferon therapy. Less frequent reactions at injection sites include vascular thrombosis, mucinosis, dermal and systemic sclerosis, necrosis, and ulceration. Here, we report a 44-year-old case diagnosed with multiple sclerosis, who developed pain and swelling following interferon-beta 1a treatment after an improperly administered intramuscular injection; and with this case report, we would like to draw attention to septal panniculitis, a serious drug complication, that develops following interferon-beta 1a treatment after an improperly administered intramuscular injection.     

Erythroderma secondary to gliclazide: a case report

Erythroderma is generalized exfoliative dermatitis, which involves more than 90% of the patient's skin. The most common cause of erythroderma is exacerbation of an underlying skin disease, malignancies or drug reaction. There is a long list of drugs responsible for erythroderma such as antiepileptics, sulfonamides, antibiotics, and angiotensin converting enzyme (ACE) inhibitors. We herein report a case of erythroderma due to gliclazide usage which is also proved by histopathologic examination and patch test. We could not find any case report of gliclazide, an oral antidiabetic, as a cause erythroderma in the literature.     

Evaluation of silicosis in ceramic workers

This study is aimed to evaluate the incidence of silicosis and the relation of it with personal and work-related factors among workers exposed to silica in ceramic factory. Workers were evaluated by respiratory symptoms, physical examination, pulmonary function and radiological findings. Occupational and Enviromental Pulmonary Disease Evaluation Questionnaire of the Turkish Thoracic Society Enviromental and Occupational Pulmonary Diseases Working Group was used. 365 of 626 workers had exposure to silica and the rest 261 were concerned as control group. There was no difference between mean age, duration of work and smoking pack year among the groups (p> 0.05). Cough and sputum rates were higher in silicosis group FEV1 and FVC values were lower in silica group but this was not statistically significant. When the two subgroups of silica group (the workers in high dust concentration and the ones in low concentration) were compared, the high concentrated group had significantly more sputum but the other symptoms and pulmonary functional parameters were not different significantly. 24 workers had parenchymal densities adjusted with pneumoconiosis. The workers with the pneumoconistic finding, had a higher mean age and longer duration of work. As a conclusion, ceramic industry has risk for silicosis. And the risk increase by time and age.     

NF‐κB activation mediates LPS‐or zymosan‐induced hypotension and inflammation reversed by BAY61‐3606, a selective Syk inhibitor,in rat models of septic and non‐septic shock

We have previously demonstrated that the activation of the spleen tyrosine kinase (Syk)/inhibitory‐κB (IκB)‐α/nuclear factor‐κB (NF‐κB) p65 signalling pathway contributes to hypotension and inflammatory response in a rat models of zymosan (ZYM)‐induced non‐septic shock. The purpose of this study was to further examine the possible mechanism underlying the effect of inhibition of Syk by BAY61‐3606 via NF‐κB activity at the level of nuclear translocation regarding the production of vasodilator and proinflammatory mediators in lipopolysaccharide (LPS) (septic)‐ and ZYM (non‐septic)‐induced shock. Administration of LPS (10 mg/kg, ip) or ZYM (500 mg/kg, ip) to male Wistar rats decreased mean arterial pressure and increased heart rate that was associated with an increase in the activities of cyclooxygenase and nitric oxide synthase, tumour necrosis factor‐α, and interleukin‐8 levels, and NF‐κB activation and nuclear translocation in sera and/or cardiovascular and renal tissues. BAY61‐3606 (3 mg/kg, ip), the selective Syk inhibitor, given 1 hour after LPS‐ or ZYM injection reversed all the above‐mentioned effects. These results suggest that Syk contributes to the LPS‐ or ZYM‐induced hypotension and inflammation associated with transactivation of NF‐κB in septic and non‐septic shock.     

Long-Term Follow-up Assessment After the Arterial Switch Operation for Correction of Dextro-Transposition of the Great Arteries by Means of Exercise Myocardial Perfusion-Gated SPECT

The arterial switch operation (ASO) is the preferred technique for correcting transposition of the great arteries, but translocation and reimplantation of the coronary arteries can produce myocardial ischemia. This report aims to describe the authors’ experience with exercise single-photon emission computed tomography (SPECT) used to evaluate myocardial perfusion. Exercise-rest gated-myocardial perfusion SPECT was performed for 69 patients (49 boys; median age, 9 years; 5th percentile [6.4 years] to 95th percentile [15.6 years]), 64 of whom were asymptomatic 9.98 ± 3.20 years after ASO. During exercise testing, the patients reached 9.85 ± 3.05 metabolic equivalents (METs) and a median heart rate of 160 beats per minute (bpm), 5th percentile (106 bpm) to 95th percentile (196 bpm). Whereas 61 patients (88.41 %) had normal myocardial perfusion, 2 patients (2.9 %) had reversible defects, and 6 patients (8.7 %) had fixed defects. All the patients with perioperative ischemic complications (4/4, 100 %) had myocardial perfusion defects, whereas four patients (4/65, 6.15 %) without ischemic complications had abnormal perfusion (p = 0.0005). Age at the time of surgery did not differ significantly (p = 0.234) between the patients with perfusion defects and those with normal study results. No significant difference was observed between the patients who had an A coronary pattern (left coronary artery originating from the left sinus and the right coronary artery originating from the right sinus, n = 47) and those who had a non-A coronary pattern (n = 22) (p = 1). The high rate for normality of exercise myocardial perfusion in our study suggests that myocardial perfusion gated-SPECT should be reserved for patients who have experienced perioperative ischemic complications or those with symptoms, at least during the first 10 years after the surgery.     

Trichosporon Asahii,Sepsis, and Secondary Hemophagocytic Lymphohistiocytosis in Children with Hematologic Malignancy

Trichosporon asahii (T. asahii) is an uncommon fungal pathogen rarely seen in patients with hematologic malignancies. Although appropriate therapy is started, infection with T. asahii usually leads to mortality. Here, we describe two patients developed severe T. asahii infection and secondary HLH. Despite rapid identification of T. asahii and negative blood cultures achieved by prompt initiation of treatment with voriconazole, fever and pancytopenia, persisted and both developed hepatosplenomegaly, and their clinical state worsened. Bone marrow aspiraton revealed hemophagocytosis. Elevated ferritin, triglyceride levels were seen. The first patient did not receive HLH directed therapy and died with multiple organ dysfunctions. Prompt diagnosis and treatment of secondary HLH led to rapid improvement in clinical and laboratory abnormalities in the second patient and kept her alive. We suggest that HLH may present as a secondary condition, accompanying a severe infection with T. asahii may, at least in part, contribute to high mortality rates in these cases.
