Effects of dental implant treatment on sleep quality in edentulous older people:a prospective cohort study

Edentulism and sleep disturbances are commonly seen among older people and cause serious negative effects on their daily lives. Edentulism can induce sleep problems by changing maxillo-mandibular anatomy and surrounding soft tissues. The effect of the treatment of complete edentulism on sleep disturbances is not sufficiently understood. The purpose of this cohort study is to detect how different treatment options affect sleep quality, daytime fatigue and sleep disorder breathing in totally edentulous elderly people. Ninety-six individulas (50 male and 46 female) participated in this prospective cohort study. The patients were non-randomly assigned to three groups, fixed implant-supported prostheses (FP), removable implant-supported prostheses (RP) and conventional total prostheses (CP). The Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS) and the STOP-Bang questionnaire were calculated before (T0) and one year after (T1) their prosthetic rehabilitations. Although there was no statistically significant difference between groups in terms of mean PSQI (p=0.524), ESS (p=0.410) and STOP-Bang (p=0.697) scores at T0, there was a significant difference between groups in terms of mean PSQI (p=0.011), ESS (p=0.030) and STOP-Bang (p=0.024) scores at T1. The FP group, when compared to CP group was associated with significantly better scores in the PSQI (? = -3.399, 95% CI= -4.612 to -2.187), ESS (? = -1.663, 95% CI= -3.149 to -0.176) and STOP-Bang (? = -0.994, 95% CI= -1.592 to -0.397). Within the limitations of this study FP was associated with a positive influence on sleep disturbances. Randomized controlled trials will be needed to provide reliable inference on this association

A neglected case of giant synovial chondromatosis in knee joint

Synovial chondromatosis is a rare benign condition arising from the synovial membrane of the joints, synovial sheaths or bursae around the joints. Primary synovial chondromatosis typically affects the large joints in the third to fifth decade of life. The purpose of this case report is to document this rare synovial pathology, which required open synovectomy and debridement to eradicate it. In our case, the biggest sized SOC was 20x19x6 cm, although there were many joint mice. Our case had the biggest SOC ever extracted, which to the best of my knowledge has not been reported earlier.Key words: Synovial chondromatosis, giant, loose body, knee Joint, surger

Henoch-Schönlein purpura in children: A cross sectional study

Background: Henoch-Schönlein purpura (HSP) is a leukocytoclastic vasculitis with small vessel involvement and mainly affects the skin as well as joints, the gastrointestinal system (GIS), kidneys, and, more rarely, other organs. Objective: The objective of this study was to evaluate the sociodemographic characteristics, and clinical and laboratory findings of patients diagnosed with HSP. Materials and Methods: This was a retrospective study done to find out the sociodemographic data, clinical, laboratory findings, and treatment information of patients diagnosed with HSP and was admitted to the Pediatric Clinic of a tertiary care hospital between January 1, 2008, and August 31, 2013. The data were obtained from the hospital’s data processing system. HSP cases were validated according to EULAR/PRINTO/PRES criteria. Mean standard deviation, median, lowest and highest, frequency, and ratio values were used in the descriptive statistics of the data. Results: The study included 85 patients between the ages of 2 and 16 years, wherein 49 patients (57.6%) were male and 36 (42.4%) were female. The mean age was 9.9±3.3 years and 53 patients (62.4%) were under 10 years of age. The most common precipitating factor was upper respiratory tract infections. Purpura was the only symptom observed in all the patients and joint involvement was the second most common symptom (60%). GIS involvement was observed in 46 patients (58.8%) and intussusception was observed in one patient. Nine patients (10.6%) had renal involvement with mild nephropathy. The most frequently observed laboratory findings were increased C-reactive protein (47%) and leukocytosis (31%). Conclusion: HSP is commonly seen in children and leads to life-threatening complications in a minority of patients. Whole patients with GIS and renal involvement should be examined and monitored to assess the severity of the disease and any complications

AN INVESTIGATION OF DIMENSIONAL STABILITY OF WOVEN FABRICS AFTER WET TREATMENTS

Tekstil malzemeleri için yaş işlem ya da yıkama sonrası boyut değişimi problemi her zaman önemli ve üzerinde çalışılan bir konu olmuştur. Yeterli kalite bilincinin oluşmadığı dönemlerde bile; geniş aralıkta da olsa belirli toleranslar oluşmuştur. Son yıllarda artan küresel rekabet ve yüksek müşteri beklentileri doğrultusunda tekstil ürünlerinin boyutsal değişimi daha kritik ve önemli bir gereklilik haline gelmiştir. Tekstil malzemeleri terbiye, renklendirme ve bitim işlemleri sırasında genelde yaş süreçlerden geçerler. Uygulanacak işlemin süreç şartları ile kimyasal ve fiziki ortamı da çok büyük farklılıklar gösterir. Doğal olarak; kumaşların ısı ve nem etkisi altında boyutsal çekmesi pek çok faktöre bağlıdır. Dolayısıyla, herhangi bir malzeme için evrensel bir çekme göstergesinin tespit edilmesi oldukça zordur. Bu çalışmada, farklı yapılardaki dokuma kumaşlarda yaş işlem sonrası ortaya çıkan kumaş çekmeleri analitik bir yaklaşımla incelenmiştir. Yapılan çalışma sonucunda örgü cinsi ve atkı sıklığı parametrelerinin atkı ve çözgü yönündeki çekme davranışlarına etkisi olduğu görülmüştür. Ancak bu etki elyaf cinsi ve kumaşı oluşturan ipliklerin dokumada kazandığı kıvrım değerlerine göre değişiklik göstermektedir. Su tutuculuğu yüksek olan pamuk lifinde suyun lif içerisine difuzyonu ile enine kesit şişmesi sonucunda ortaya çıkan boyutsal kararsızlık, hidrofob ve yüksek sıcaklıkta ön fikse işlemi yapılmış poliester kumaşa göre daha fazladır. Yün lifinde higral genleşmenin boyutsal stabilite üzerine etkisi büyüktür. Yün kumaşlara ön işlem olarak uygulanan dekatür işlemi ile elde edilen fiksaj etkisi, daha sonraki yaş işlemlerde higral genleşme oranlarını ve dolayısıyla kumaşın çekme davranışını doğrudan etkilemektedir.For textile materials, the problem of dimensional change after wet processing or washing has always been an important and overworked issue. Even during periods when adequate quality awareness does not occur; there are certain tolerances even in a wide range. In recent years, with increasing global competition and high customer expectations, the dimensional change of textile products has become a more critical and important requirement. Textile materials generally pass through wet processes during pre-treatment, coloring and finishing operations. The process conditions, chemical and physical medium of the process to be applied are varied. Consequently, the dimensional stability of the fabrics exposed to heat and humidity depends on many factors. Therefore, it is quite difficult to determine universal contraction values for any material. In this study, the contraction behaviour of woven fabrics in different structures, after wet processing are invetigated with an analytical approach. It is observed that the weave type and weft density parameters affect the contraction behavior in weft and warp direction. However, this effect varies according to the fiber type and the crimp values of the yarns forming the fabric. The dimensional instability resulting from the swelling of the cross-section through the diffusion of water into the fiber is greater in case of the water-retaining cotton in comparison with that of the hydrophobic and high temperature pre-treated polyester fabric. The effect of hygral expansion in wool fiber stability is great. The fixation effect obtained by decatizing applied to wool fabrics as a pretreatment directly affects the hygral expansion rates and hence the dimensional stability behavior of the fabric in subsequent wet processes
