Seyma Yildiz MD Huseyin Toprak MD Yeliz Emine Ersoy MD Fatma Ümit Malya MD Ayşe Ahsen Bakan MD Ayşe Aralaşmak MD Zuhal Gucin MD 《The breast journal》2018,24(2):176-179
Papillary lesions have a broad spectrum of appearances on magnetic resonance imaging (MRI ). The purpose of this study was to evaluate whether apparent diffusion coefficient (ADC ) values of papillary lesions can be used to characterize lesion as benign or malignant. This retrospective study included 29 papillary lesions. Diagnostic values of dynamic contrast‐enhanced MRI (DCE‐MRI), DWI ‐ADC , and DCE ‐MRI plus DWI ‐ADC were separately calculated. The malignant papillary lesions (0.744×10?3 mm2/s) exhibited significantly lower mean ADC values than the benign lesions (1.339×10?3 mm2/s). Addition of DWI to standard DCE ‐MRI provided 100% sensitivity. We hypothesized that this combination may prevent unnecessary excisional biopsies. 相似文献

This experimental study was designed to assess and to compare intra-abdominal adhesions following the use of five commercially available prosthetic mesh grafts in the repair if abdominal wall defects. Sixty Wistar albino rats were randomly divided into six groups (n = 10). A 2 × 1 cm defect at abdominal wall was created and defects were closed either primarily or with one of the following prosthetic mesh grafts: monofilament polypropylene, polytetrafluoroethylene, sodium hyaluronate/carboxymethylcellulose-coated polypropylene, polypropylene/polyglactin 910 composite, or resorbable hydrophilic collagen-coated multifiber polyester. The severity of adhesions was graded, tensile strengths of adhesions were measured, and histopathological grades of inflammation and fibrosis were evaluated. Polypropylene mesh resulted in more adhesion formation in comparison to primary repair and other grafts used in this study, except polypropylene/polyglactin 910 composite mesh. In addition, the highest tensile strength of omental adhesions was detected in the polypropylene group (χ2 = 26.249; p =. 0001). Polyester composite mesh caused the least adhesion formation among the groups. Sodium hyaluronate/carboxymethylcellulose-coated polypropylene and polyester composite meshes revealed the highest fibrosis scores (χ2 = 50.776; p =. 0001). The highest inflammatory activity was detected in the polytetrafluoroethylene mesh group (χ2 = 16.564; p =. 005). Thus, sodium hyaluronate/carboxymethylcellulose-coated polypropylene and polytetrafluoroethylene meshes following polyester composite mesh were the minimal adhesion-forming grafts in this study. Disadvantages of the polytetrafluoroethylene mesh were lower fibrotic activity and higher inflammatory reaction to the graft. 相似文献

Increased serum insulin levels and reduced peripheral insulin activities seen in insulin resistance syndrome are associated
with age-dependent cognitive impairment and Sporadic Alzheimer’s Disease (SAD), suggesting a disturbance in the insulin signalling
system in the brain and possibly being one of the causes of dementia. Therefore, the streptozotocin (STZ)-induced animal may
be an appropriate model for the investigation of SAD and related dementia. This study was designed to investigate the beneficial
effect of Curcumin (CUR), a neuroprotective agent, on intracerebroventricular (ICV) STZ-induced cognitive impairment in rats.
For this purpose, adult male Wistar rats were bilaterally ICV injected with STZ (3 mg/kg). An artificial cerebrospinal fluid
(aCSF) was given to the control group (SHAM) instead of STZ on days 1 and 3. Learning and memory performance were assessed
using the “passive avoidance task” and the “Morris water maze test”. After confirmation of acquisition impairment with these
tests, the STZ group was divided into two subgroups: STZ + vehicle (Vh) and STZ + CUR. The rats in the SHAM and STZ + Vh groups
were administered intraperitoneally with 0.5 ml Vh and the rats in the STZ + CUR group were treated intraperitoneally with
CUR (300 mg kg−1 day−1 in Vh) for 10 days starting from the 25th day after STZ injection. The Morris water maze test was reapplied on the 35th day
after STZ injection and all of the rats were sacrificed on day 36 for quantitation of IGF-1 and for histopathological evaluation.
Rats in the STZ + CUR group were found to have a higher performance in cognitive tests than rats in the STZ + Vh group (P < 0.01). In parallel with the cognitive tests, IGF-1 levels were decreased in all of the STZ-injected groups (1.78 ± 0.34)
compared to the SHAM group (3.46 ± 0.41). In contrast, CUR treatment significantly increased IGF-1 levels (P < 0.001). The degree of neuronal loss decreased after CUR treatment compared to the SHAM group (P < 0.02). These results clearly indicate that CUR treatment is effective in reducing the cognitive impairment caused by STZ
in rats, and may be a potential therapeutic agent for altering neurodegeneration in SAD. 相似文献

Plasma isoniazid and rifampin concentrations, but not pyrazinamide and ethambutol concentrations, were decreased by about 50% (P < 0.05) in diabetic pulmonary tuberculosis patients. The prevalences of subnormal plasma isoniazid, rifampin, pyrazinamide, and ethambutol concentrations were 49% or 100% (P < 0.01), 66% or 100% (P < 0.05), 30% or 50% (P = 0.198), and 32% or 21% (P = 0.742) in nondiabetic or diabetic tuberculosis patients, respectively. These data show that plasma concentrations of isoniazid and rifampin were greatly reduced in diabetic tuberculosis patients. 相似文献

Dissection of the carotid artery can occur intracranially or extracranially, although dissections tend to affect extracranial
segments of the arteries much more commonly than intracranial segments. Carotid artery dissection (CAD) is most common in
middle-aged women. Although not completely known, the main risk factors related to carotid artery dissection are genetic and
environmental factors, traumatic events, cervical manipulation, migraine, recent infections, hyperhomocysteinemia, and hereditary
connective tissue disorders. Although some cases of bilateral internal CAD have been reported, spontaneous bilateral dissections
are rare. Prolonged hoarseness is usually due to using the voice either too much, too loudly, or improperly over an extended
period of time. Disorders leading to dysphagia may affect the oral, pharyngeal, or esophageal phases of swallowing. In this
study we report on a patient with bilateral CAD who presented to our clinic with dysphagia and hoarseness. 相似文献

Purpose
This study aimed to investigate the extent of knowledge and use of emergency contraception among women of reproductive age and to identify barriers existing in Turkey in this context. There is limited research regarding the knowledge and use and barriers to emergency contraception use, since the prepackaged form of hormonal emergency contraception has been available over the counter in Turkey. 相似文献140.

The location and incidence of the zygomaticofacial foramen (ZFF) was studied in 80 dry skulls (160 sides) of unsexed adult skulls of West Anatolian people. The average distances from the ZFF to the frontozygomatic suture, to the zygomaticomaxillary suture, and to the inferior orbital rim were found to be 26.2 ± 3.2 mm, 18.6 ± 3.14 mm, and 5.94 ± 1.43 mm, respectively. The zygomas were evaluated for the number of foramina on their facial aspects. There was none in 25 (15.6%), one in 71 (44.4%), two in 45 (28.1%), three in 10 (6.3%), four in seven (4.4%), and five in two (1.3%) sides. The ZFF was also studied for its distribution around the zygoma by dividing the surface into four anatomical areas. There was no statistical difference between the morphometrical results on both sides. Data regarding the location and variation in the number of the ZFF is important in avoiding zygomatic nerve and vessel injury during surgery, but by virtue of the great variability found, ZFF is an unreliable landmark for maxillofacial surgery.
