INTRODUCTION: Chronic constipation is very common in elderly patients. As a result of this situation fecaloma is also frequently seen at these ages. However, the stercoral perforation caused by fecaloma is a rare situation to occur. The rectosigmoid colon is the most affected colonic segment. It is seen in older patients with concomitant diseases and a low quality of life. PRESENTATION OF CASE: Here in this case, we have to report an 83 - year-old male patient who came to the emergency room with complaints of abdominal pain and constipation for two days...

BACKGROUND: Prolonged QRS duration is associated with decreased left ventricular (LV) systolic function. However, the relation between LV restrictive filling pattern (RFP) and QRS duration has not been investigated yet. The purpose of our study was to assess this relationship. METHODS: We analyzed standard 12-lead surface electrocardiogram (ECG) of 155 consecutive patients. Mitral inflow and septal tissue velocities were obtained using the apical 4-chamber view with pulsed Doppler echocardiography...

Fluorescence based microarray detection systems provide sensitive measurements, however variation of probe immobilization and poor repeatability negatively affect the final readout, and thus quantification capability of these systems. Here, we demonstrate a label-free and high-throughput optical biosensor that can be utilized for calibration of fluorescence microarrays. The sensor employs a commercial flatbed scanner, and we demonstrate transformation of this low cost (100 USD) system into an Interferometric Reflectance Imaging Sensor through hardware and software modifications...

Affective touch plays an important role in children's social interaction and is involved in shaping the development of the social brain. The positive affective component of touch is thought to be conveyed via a group of unmyelinated, low-threshold mechanoreceptive afferents, known as C-tactile fibers that are optimally activated by gentle, slow, stroking touch. Touch targeting these C-tactile fibers has been shown to decrease the heart rate in infants. The current study investigated the relationship between age and psychophysical ratings in response to affective touch...

Background Dual-energy computed tomography (DECT) has conceptually been known since the late 1970s and commercially available as dual-source CT (DSCT) systems since 2006; however, the technique has not yet seen widespread implementation in routine protocols. Part of the cause for this is likely due to misconceptions about radiation dose and/or image quality when using DECT. Purpose To compare image quality and radiation dose of single-energy CT (SECT) and DECT abdominal examinations obtained in clinical practice on a second generation DSCT...

How forward and backward walking, both central to everyday life, relate to cognition are relatively unexplored in people with dementia. This study aimed to investigate if forward and backward walking velocity respectively, associated with global cognition and executive function in people with dementia, and whether the association differed according to walking aid use or dementia type. Using a cross-sectional design, 161 participants (77% women), a mean Mini-Mental State Examination (MMSE) score of 15, and mean age of 85...

PURPOSE: To evaluate the use of subtenon amikacin injection for the treatment of Nocardia asteroides orbital cellulitis in a patient with a history of scleral buckle surgery. METHODS: Case report. RESULTS: A 79-year-old diabetic woman presented with an 8-month history of diplopia, discharge, and swelling around her left eye. She had a scleral buckle surgery in this eye about 15 years ago.

Metal halide perovskites have emerged as materials of high interest for solar energy to electricity conversion and in particular the use of mixed ion structures has led to high power conversion efficiencies and improved stability. For this reason, it is important develop means to obtain atomic level understanding of the photo-induced behaviour of these materials including processes such as photo-induced phase separation and ion migration. In this paper, we implement a new methodology combining visible laser illumination of a mixed-ion perovskite ((FAPbI3)0...

OBJECTIVE: To evaluate the impact of nasal septum deviation (NSD) and septoplasty on eustachian tube (ET) functions. MATERIAL AND METHODS: The study was designed as a prospective controlled study and conducted in a tertiary referral center. A study group of 25 patients who were scheduled for septoplasty for NSD; and a control group of 25 healthy individuals having no ear or nose symptoms were formed. Tympanometric analysis of ET function, subjective and objective analysis of nasal functions with acoustic rhinometry and rhinomanometry were performed...

Objective The aim of this study was to evaluate, quantitatively, the volumetric effects of stabilization splint therapy on the masseter muscle of sleep bruxism (SB) patients. Methods The magnetic resonance (MR) images of 16 SB patients diagnosed by polysomnography (PSG) who used stabilization splints for four months were obtained before and after the therapy. The masseter muscle volume was calculated using Cavalieri's principle on the MR images. Results After the splint therapy, the mean volume of the masseter muscle did not reduce significantly...

Most of the model lipid membrane studies on gold involve the usage of various surface-modification strategies to rupture liposomes and induce lipid bilayer formation since liposomes with polar surfaces do not interact with bare, hydrophobic gold. In this study, a thiol-modified phospholipid, 1,2-Dipalmitoyl-sn-Glycero-3-Phosphothioethanol (DPPTE) was incorporated into phosphatidylcholine (PC) based liposomes to form supported lipid bilayer (SLB) on gold surfaces without further modification. The binding kinetics of liposomes with different DPPTE ratio (0...

BACKGROUND: Few treatments with a distinct mechanism of action are available for patients with platinum-refractory advanced or metastatic urothelial carcinoma. We assessed the efficacy and safety of treatment with docetaxel plus either ramucirumab-a human IgG1 VEGFR-2 antagonist-or placebo in this patient population. METHODS: We did a randomised, double-blind, phase 3 trial in patients with advanced or metastatic urothelial carcinoma who progressed during or after platinum-based chemotherapy...

BACKGROUND: Human, hairy skin contains a subgroup of C-fibers, the C-low threshold mechanoreceptive afferents ((C-LTMR) C-tactile or C-touch (CT) fibers) that are linked with the signaling of affective aspects of human touch. Recent studies suggest an involvement of these afferents in the modulation of pain in healthy volunteers. Small fiber neuropathy (SFN) is associated with a damage of C-fibers. Therefore, an impairment of C-LTMRs can be assumed. We aimed to elaborate a possible role of CT-afferents in pain modulation by investigating healthy volunteers and SFN-patients...

MATERIALS AND METHODS: This retrospective study included 189 patients hospitalized for OHSS following ICSI treatment in a tertiary in vitro fertilization unit between 2006 and 2014. Pigtail catheters were applied in 63 patients; the other 126 patients did not need that treatment...

The aim of this study was to determine if there is a seasonal variation in the widely used heart failure marker NT-proBNP. The study included all primary care requests for NT-proBNP in the county of Uppsala, Sweden, between January 2007 and December 2015. For seasonal variation, the NT-proBNP results for individual months were compared. The NT-proBNP values were highest in July to September, but there was also a minor peak in December-January. In conclusion, a seasonal periodicity for NT-proBNP was demonstrated in primary care patients...

INTRODUCTION: Lung cancer, a common malignancy and cause of cancer-related deaths, is strongly linked to several environmental exposures, and thus primarily affects the elderly. Formerly a man's disease, its incidence is rising among women, and lung cancer is now more common in women than men in Sweden. Women are particularly over-represented among young patients. While overall cancer mortality in Europe is decreasing, female lung cancer mortality is increasing. OBJECTIVES: We describe the epidemiological presentation of lung cancer in young Swedish women, aiming to pinpoint its risk factors for young women...
