Is microRNA 1910-3p (miR-1910-3p) a really distinctive marker for psoriasis?

Background/aimAlthough the cause of immune activation in the pathogenesis of psoriasis is still unclear, miRs are thought to have an effect on psoriasis. This work aimed to evaluate the role of miRs (miR-4649-3p, miR-6867-5p, miR-4296, miR-210, and miR-1910-3p) that target the FOXP3 mRNA and IL-17A mRNA in psoriasis. Materials and methods Forty-four psoriasis patients and 44 healthy controls were included in the study. Quantitative real-time PCR (qRT-PCR) was used for the measurement of miRs. Serum IL-17A levels were determined by an enzyme-linked immunosorbent assay (ELISA) method. Results Plasma miR-1910-3p levels were significantly lower in the patient group than the controls (P = 0.000, fc: 0.10). ROC analysis showed that plasma miR-1910-3p levels could significantly differentiate psoriasis patients from healthy controls [AUC = 0.912 (0.848–0.975), P = 0.000]. The plasma miR-4649-3p level was significantly higher in the psoriasis group compared to the controls (P = 0.000, fc: 2.99). Conclusion Decreased expression of miR-1910-3p increases the risk of developing psoriasis by approximately 50-fold and was able to use for the significant differentiation of psoriatic patients from healthy controls.     

Fournier's gangrene: Report of thirty-three cases and a review of the literature

Background: Fournier’s gangrene (FG) is an extensive fulminant infection of the genitals, perineum or the abdominal wall. The aim of this study is to share our experience with the management of this difficult infectious disease. Methods: Thirty‐three male patients were admitted to our clinic with the diagnosis of FG between February 1988 and December 2003. The patient’s age, etiology and predisposing factors, microbiological findings, duration of hospital stay, treatment, and outcome were analyzed. The patients were divided into two groups. The first 21 patients (Group I) were treated with broad‐spectrum triple antimicrobial therapy, broad debridement, exhaustive cleaning, and then they underwent split‐thickness skin grafts or delayed closure as needed. The other 12 patients (Group II) were treated with unprocessed honey (20–50 mL daily) and broad‐spectrum triple antimicrobial therapy without debridement. Their wounds were cleaned with saline and then dressed with topical unprocessed honey. The wounds were inspected daily and the honey was reapplied after cleaning with normal saline. Then, the patients’ scrotum and penis were covered with their own new scrotal skin. Results: The mean age of the patients was 53.9 ± 9.56 years (range = 23–71). The source of the gangrene was urinary in 23 patients, cutaneous in seven patients, and perirectal in three patients. The predisposing factors included diabetes mellitus for 11 patients, alcoholism for 10 patients, malnutrition for nine patients, and medical immunosuppression (chemotherapy, steroids, malignancy) for three patients. The mean duration of hospital stay was 41 ± 10.459 (range = 14–54) days. Two patients in Group I died from severe sepsis. The clinical and cosmetic results were better in Group II than Group I. Conclusions: Necrotizing fasciitis of the perineum and genitalia is a severe condition with a high morbidity and mortality. Traditionally, good management is based on aggressive debridement, broad‐spectrum antibiotics, and intensive supportive care but unprocessed honey might revolutionize the treatment of this dreadful disease by reducing its cost, morbidity, and mortality.     

The effect of being overweight on survival in patients with gastric cancer undergoing adjuvant chemoradiotherapy

EROGLU C., ORHAN O., KARACA H., UNAL D., DIKILITAS M., OZKAN M. & KAPLAN B. (2013) European Journal of Cancer Care 22 , 133–140 The effect of being overweight on survival in patients with gastric cancer undergoing adjuvant chemoradiotherapy The aim of this study was to examine the effect of being overweight on survival in patients with gastric cancer undergoing adjuvant chemoradiotherapy and chemotherapy. In this study 152 patients were evaluated. Radiotherapy dose was 45 Gy given in 5 weeks. 5-FU 425 mg/m² and folinic acid 20 mg/m² were administered weekly during the radiotherapy and four cycles with 4-week intervals as consolidation chemotherapy after radiotherapy. Patients were assigned into two groups according to their body mass index: overweight (body mass index ≥25 kg/m²) and normal weight (body mass index <25.0 kg/m²). The median overall survival was 39 months vs. 18 months and median disease-free survival was 27 months vs. 13 months in the overweight and normal-weight groups respectively (P= 0.004 and P= 0.006 respectively). The 5-year survival was better in the patients with overweight than those with normal weight (42% vs. 17%; P= 0.004). The overall survival was significantly better with being overweight and early pathological stage (P= 0.016 and P= 0001 respectively). Overall survival, disease-free survival and long-term survival in patients with gastric cancer undergoing adjuvant treatment were better in overweight than normal-weight patients. Moreover, it was shown that body mass index and pathological stage were associated to survival and prognosis.     

Value of selective upper tract cytology for recognition of upper tract tumors after treatment of superficial bladder cancer

Background: The value of selective upper urinary tract (UT) cytology in patients who are asymptomatic and tumor free at control cystoscopy after being treated for superficial bladder carcinoma has not been studied. The present study was performed to evaluate the value of selective UT cytology in patients who are tumor free at control cystoscopy after being treated for superficial bladder cancer. Methods: Forty‐seven consecutive patients who had undergone definitive surgical treatment for superficial bladder cancer at least 24 months prior and were tumor free at control cystoscopy were evaluated with bladder wash for cytology as well as selective UT urine cytology by catheterization of both ureteral orifices. Of the 47 patients, disease was stage Ta in 30 (63.8%), T1 in 15 (31.9%) and Ta/Tcis in 2 (4.3%). Primary tumor was unifocal in 24 (51.1%) and multifocal in 23 (48.9%) patients. The time elapsed from the initial diagnosis to the last evaluation ranged from 2 to 21 years (mean 5.39). Results: UT cytology was positive in 2 cases. Although, excretory urography (IVP) revealed mild pelvicalicectasis in 1 of these 2 patients, ureterorenoscopy (URS) revealed no abnormality. In the other patient with normal IVP and retrograde pyelography (RGP), URS revealed a ureteral tumor 5 mm in diameter. Although the UT cytology was normal in the remaining 45 patients, IVP revealed right hydronephrosis in 1 patient and URS revealed multiple ureteral tumors. Conclusion: Given the normal appearance of the UT, it is highly unlikely that these patients have tumor in the UT. Thus, during the follow‐up of patients with superficial bladder cancer, it is not useful to perform UT select cytology in the absence of any identifiable filling defects in the upper urinary tract.     

Prevalence and characteristics of Hymenoptera venom allergy in urban school children aged 6 to 18 years living in Trabzon

Background/aim Hymenoptera venom allergy is one of the leading causes of systemic allergic reactions in both adults and children. The present study was conducted to evaluate the prevalence and characteristics of Hymenoptera venom allergy in urban school children aged 6 to 18 years living in Trabzon.Materials and methods In this cross-sectional, two-level survey study, children were recruited using random sampling of public primary and secondary schools. Firstly, parents were asked about their child’s age and sex and whether their child had ever been stung by any kind of bee. When they responded “yes” to the last question, they attended a face-to-face interview at the outpatient clinic for the second part of the survey, which included information about history of insect stings and the presence of atopic diseases.Results Of 17,000 children, 7904 (46.5%; 3718 males, 47.0%) returned the first-level questionnaire. A total of 4312 (54.5%) were stung at least once in their lifetime. Males had a significantly higher risk of being stung (59.4%, odds ratio: 1.44, 95% confidence interval: 1.32–1.58, p < 0.0001). The second-level questionnaire was completed for 545 (12.6%) of the children. Of 950 stings reported in 545 children, 5.2% were large local reactions (LLRs), 1.9% were generalized cutaneous reactions (GCRs), and 1.3% were systemic reactions (SRs). The stinging insect was Apis mellifera and Vespula in 66.2% and 33.8% of stings, respectively (p < 0.001).Conclusion Hymenoptera stings are common in urban school children living in Trabzon. The most common type of allergic reaction is LLR and the most reported stinging insect is Apis mellifera .     

Results of the ureteral reimplantation with serous-lined extramural tunnel in orthotopic ileal W-neobladder

Background: Our experience in uretero‐ileal anastomosis using the serous‐lined extramural tunnel in orthotopic ileal W‐neobladder is presented. Methods: Between June 1998 and November 2001, 42 patients (40 men and two women) underwent radical cystectomy and orthotopic ileal neobladder for invasive bladder cancer. The ureters were reimplanted into serous‐lined extramural tunnels as described by Abol‐Enein and Ghoneim. However, we made minor modifications during the ureteral reimplantation in cases that necessitated distal ureteral excision and with grossly dilated ureters. Evaluation included clinical and radiographic studies to determine functional and oncological outcomes. Results: There was no operative mortality. The mean follow‐up period was 28 months (range 12–52). Early complications occurred in four patients (9.5%). An endarterectomy for acute popliteal arterial embolism, the excision of the pouchointestinal fistula and a temporary colostomy were performed in two of these four patients. The other two patients were treated conservatively. Late complications occurred in eight patients (19%). Reflux was observed in three renal units (3.7%), ureterointestinal strictures in another three renal units (3.7%) and urethroileal stenosis in two patients (4.8%). In all cases, stabilization or improvement of renal function was achieved. No metabolic complications were observed. Conclusions: Ileal W‐neobladder with a serous‐lined extramural tunnel is a safe, reliable form of lower urinary tract reconstruction. The method can be carried out with equal ease in grossly dilated ureters and in cases that necessitate distal ureteral excision.     

Lipomatosis of the bladder presenting as bladder cancer

A case of bladder lipomatosis in an 81-year-old man is presented. The preoperative diagnosis was bladder tumor. A transurethral resection of the bladder was performed and a pathological examination revealed lipomatosis of the bladder. This entity is extremely rare and, to our knowledge, this is the second case reported in the English published works.     

APOLIPOPROTEIN E POLYMORPHISM AND STROKE IN A POPULATION FROM EASTERN TURKEY

Human apolipoprotein E (apo E) alleles are polymorphic with significantly different frequencies among different ethnic groups and have been associated with increased risk of coronary heart disease, and postulated as a major genetic susceptibility locus for Alzheimer's disease. Studies undertaken in different populations have shown different association patterns between apo E genotype and stroke. The aim of this study was to determine the risk of apo E genotype in stroke patients living in the eastern part of Turkey. The apo E genotypes and allele frequencies of 229 individuals from the same geographic area were determined by polymerase chain reaction and restriction fragment length polymorphism, of which 103 were patients with a documented history of stroke without other apparent dementia and 126 age-matched healthy subjects as a control group. A reduced E3/4 genotype frequency was found in subjects with stroke and the E2/3 genotype frequency was elevated in patients with previous stroke. There was no association between apo E ε4 allele and stroke. The APOE alleles had divergent effects in this population. Association between APOE (the gene) alleles and stroke in this population may be altered due to interaction with other genetic effects. The effects of APOE alleles and genotypes require further study in different populations.
