BACKGROUND Changes in the attitudes and behavior of relatives of breast cancer patients concerning cancer prevention and screening after diagnosis in a loved one were evaluated. MATERIALS AND METHODS Forty-three questions were used to collect data from the relatives of the breast cancer patients who had been living with their relatives for at least one year. RESULTS The study group was composed of 171 female relatives (median age: 43, range: 17-82 yr). After the patients were diagnosed with breast cancer, changes in the attitudes and behavior of their relatives toward the prevention and screening of cancer were evident in 78 (45.6%) of the study participants (e.g. eating habits, quit or reduced smoking , exercise habits). In addition, it was noted that some characteristics of the relatives had different effects on different attitudes and behavior. CONCLUSIONS Awareness on breast cancer among the relatives of breast cancer patients is useful for the management of health and social problems that can be seen in these individuals. At the same time, this information could help countries determine whether their actual level of healthcare for early cancer diagnosis, prevention, and screening are adequate.

Granular cell tumors (GCTs) are extremely rare neoplasms of the bladder. In the literature, there are only a few reported cases. We present a GCT case with clinical, radiological, histomorphological, immünohistochemical findings and its differential diagnosis.

Diffusion‐weighted imaging (DWI) is a noncontrast‐enhanced MRI technique. There are new promising studies on the use of DWI as a part of the enhanced or unenhanced abbreviated breast MRI protocols.

We report the case of a 26-year-old woman with a body mass index (BMI) of 51 kg/m2 who was not having any metabolic diseases was prepared for obesity surgery. No pathologies were detected in the abdominal ultrasound or upper gastrointestinal system endoscopy taken before the operation. Abdominal computerized tomography was obtained which revealed a nodular lesion causing mural thickening on the anterior wall of the antrum. The mini-gastric bypass surgery procedure was performed with subtotal gastrectomy to remove the mass. The final diagnosis of gastric adenomyoma was made. Although gastric adenomyomas are rare, they should always be kept in mind in the differential diagnosis of extramucosal gastric lesions.

Contribution of diffusion-weighted imaging to conventional MRI for detection of haemorrhagic infarction in ovary torsion

BackgroundTo assess the role of DWI in differentiation haemorrhagic ovary infarction from non-haemorrhagic one.MethodsFor this prospectively designed study, of 117 female patients who presented with acute lower quadrant pain and underwent MRI for suspicion of ovary torsion, results of only 29 patients (mean age, 24.7; SD, ±5.7; age range, 18–37), with surgical and pathological confirmation of adnexal torsion, were included to the study. All patients underwent DWI after conventional MRI. Quantitative and qualitative analysis of both the torsed and contralateral normal ovary were performed. Results of conventional MRI and DWI were noted.ResultsAt operation 15 patients were found to have haemorrhagic infarction while 14 had non-haemorrhagic infarction. Of the 29 patients, 17 torsed ovaries could be salvaged in a viable state. We found statistically significant correlation of the ADC values, between haemorrhagic and non-haemorrhagic ovary infarction. The ADC values were significantly lower in patients with haemorrhagic infarction than non-haemorrhagic ones (p < 0.001). Using an ADC threshold of 1.27, the sensitivity of DWI for haemorrhagic infarction was 0.93 and specificity 0.85.ConclusionDWI may be used with a significant success for the preoperative diagnosis of haemorrhagic infarction. This may be alerting for pre-emptive surgery in avoiding serious complications and preventing irreversible structural damage of the ovary.

Objective We aimed to search the contribution of diffusion-weighted imaging (DWI) in follow-up of patients with acute appendicitis associated inflammatory appendiceal mass (IAM). DWI was used as a monitoring imaging method to assess the response of medical treatment. Materials and methods 19 patients (mean age, 37+–13.1; age range, 19–69; M/F: 10/9), presented with clinical, laboratory and computed tomography (CT) findings suggestive of IAM were enrolled prospectively in this study. CT and DWI images were evaluated by two radiologists in consensus. b values 0, 500 and 1000 s/mm2 were used, and DWI images were analysed both qualitatively and quantitatively. Laboratory parameters were C-reactive protein value and white blood cell count. During follow-up changes in the diameter of IMA and laboratory parameters were correlated with ADC values. Conservative treatment with interval appendectomy and a total conservative approach without surgery were the treatment options during follow-up. Results We found statistically significant correlation between the ADC values, maximum IAM diameter and laboratory parameters. During follow-up five surgical procedures were performed: one patient underwent surgery for cecal adenocarcinoma and four underwent interval appendectomy. One patient developed acute relapse of IAM at the sixth month of follow-up. Conclusion DWI may be used with a significant success for follow-up of patients with IAM. As a monitoring imaging method, DWI may also aid in determining of most appropriate timing for interval appendectomy as well as may help in diagnosing alternative diagnoses (e.g. malignancy and inflammatory bowel disease) that can mimic IAM.
