The incremental value of magnetic resonance imaging for breast surgery planning

Purpose

The aim of this study was to evaluate the effect of breast magnetic resonance imaging (MRI) on preoperative or intraoperative surgical planning.

Methods

One hundred and sixty females with breast cancer were enrolled in the study. The contribution of MRI compared to MMG and USG, their histopathological concordance, and their impact on surgical treatment were evaluated prospectively.

Results

In 48 (30.0%) of the patients, MRI identified suspicious lesions that were not detected by MMG and USG. The diagnosis by MRI was accurate in 17 (10.6%) of them, while in remaining 31 patients (19.4%) the additional lesions found by MRI and interpreted as malignant were found not to be malignant. The pathological accordance of MRI and MMG compared with USG were 69.3 and 70.0%, respectively, whereas individually, MMG and USG were in accordance with the pathological examination in 52.9 and 67.9% of the cases, respectively.

Conclusions

Assessment of the tumor size, multifocality, multicentricity, and presence of ductal carcinoma in situ by MRI may lead to misinterpretations in the majority of patients. The surgical approach should not be changed based solely on MRI findings. An accurately interpreted MMG combined with USG may be sufficient in most cases.     

Attention-deficit hyperactivity disorder in patients with premature ejaculation: a pilot study

Purpose

The etiology of both adult-type ADHD and PE is not completely understood, but the studies revealing common etiologic factors for both conditions suggest a high likelihood of coexistence. We aimed to find out the prevalence of ADHD among adult males with lifetime PE.

Methods

The patients with lifetime PE were included in the study. Both patients and controls were evaluated with the 10-item premature ejaculation index of Althof and Rosen for premature ejaculation, Wender Utah rating scale (WURS) and Conner’s adult ADHD rating scales (CAARS) for determining the presence of attention-deficit hyperactivity disorder syndrome.

Results

A total of 38 patients and 27 controls were included in the study. Patient and control groups were similar in terms of age and (p < 0.878), but different IELT (p < 0.001). ADHD was detected in 16 (42.1 %) of patients with PE, while ADHD symptoms were detected in only 1 (3.7 %) of control patients. Distribution of patients in the study group according to ADHD types was as follows: Type 1, Type 2, Type 3 in 2 (5.3 %), 4 (10.5 %), and 10 (26.3 %) patients, respectively.

Conclusions

ADHD is significantly more frequent among patients with PE than controls. The close relationships between these two diseases must be examined by prospective studies.     

Endothelial Nitric Oxide Synthase Gene Intron 4 (VNTR) Polymorphism and Vascular Access Graft Thrombosis

Vascular access thrombosis is a leading cause of vascular access failure in hemodialysis patients. Thrombosis is a multifactorial condition and genetic makeup can affect thrombosis risk. We conducted a study to investigate for possible associations between ecNOS gene intron 4 variable-number tandem repeat (VNTR) polymorphism and thrombosis of polytetrafluoroethylene hemodialysis arteriovenous access grafts (AVG) in Turkish patients. Fifty-five patients with end-stage renal disease who had AVGs implanted between 2000 and 2002 and 167 healthy individuals representing our healthy population were enrolled in this prospective study. Each subject provided a venous blood sample from which DNA was isolated, and polymerase chain reaction analysis was done to identify genotypes (aa, bb, ab) for ecNOS gene intron 4 VNTR polymorphism. All grafts were placed in brachioaxillary position. The subjects were divided into two groups based on duration of graft patency. The thrombosis group (Group I) comprised 26 patients who developed AVG thrombosis in the first 12 months after placement. The no-thrombosis group (Group II) comprised 29 patients whose grafts remained patient for at least 12 months. The frequency of the aa genotype in Group I was significantly higher than that in Group II (p =. 005). At 6, 12, and 24 months, the primary patency rates for the AVGs in patients with the aa genotype were significantly lower than the corresponding rates for the bb and ab genotype groupings (p =. 01, p =. 01 and p =. 04 for the three respective time points; Kaplan–Meier). ecNOS gene intron 4 VNTR polymorphism is linked with the pathogenesis of vascular access thrombosis in Turkish patients undergoing hemodialysis.     

Anger in women with premenstrual dysphoric disorder: Its relations with premenstrual dysphoric disorder and sociodemographic and clinical variables

Purpose

The aim of the present study was to investigate anger and anger levels in women meeting the criteria of Premenstrual Dysphoric Disorder and to determine the relation between anger levels and the severity of PMDD and other variables.

Methods

50 women meeting the criteria of Premenstrual Dysphoric Disorder and 50 healthy controls were included in the study. Sociodemographic, familial and reproductive period characteristics of the women participating in the study were recorded. All subjects were administered the State–Trait Anger Scale and Premenstrual Syndrom Scale scales.

Results

A significant difference was found between the Premenstrual Dysphoric Disorder group and the healthy control group in terms of Premenstrual Syndrom Scale scores and anger sub scores. When the state trait anger scale scores were examined, it was seen that subscles had higher scores compared to healthy women. In Premenstrual Dysphoric Disorder group; there was a positive correlation between Premenstrual Syndrom Scale scores and trait anger, anger-in and anger control scores.

Conclusions

Anger appears to be an important problem that makes life more difficult for subjects with Premenstrual Dysphoric Disorder. Wide-scale further studies focused on anger and its relation with Premenstrual Dysphoric Disorder are needed to develop ways of coping with anger in Premenstrual Dysphoric Disorder.     

β-Glucan and Dark Chocolate: A Randomized Crossover Study on Short-Term Satiety and Energy Intake

Aim: The aims of this study were to adapt a traditional recipe into a healthier form by adding 3 g of oat β-glucan, substituting milk chocolate to dark chocolate with 70% cocoa, and to examine the effect of these alterations on short-term satiety and energy intake. Materials and Methods: Study subjects (n = 25) were tested in a randomized, crossover design with four products closely matched for energy content. Four different versions of a traditional recipe including milk chocolate-control (CON), oat β-glucan (B-GLU), dark chocolate (DARK) or oat β-glucan and dark chocolate (B-GLU + DARK) were given to subjects on different test days. After subjects were asked to report visual analog scale (VAS) scores on sensory outcomes and related satiety for four hours ad libitum, lunch was served and energy intake of individuals was measured. Results: VAS scores indicated that none of the test foods exerted an improved effect on satiety feelings. However, energy intake of individuals during ad libitum lunch was significantly lower in dark chocolate groups (CON: 849.46 ± 47.45 kcal versus DARK: 677.69 ± 48.45 kcal and B-GLU + DARK: 691.08 ± 47.45 kcal, p = 0.014). Conclusion: The study demonstrated that substituting dark chocolate for milk chocolate is more effective in inducing satiety during subsequent food intake in healthy subjects.     

Hepatic failure due to CD3+ plasma cell infiltration of the liver in multiple myeloma

We present a case of multiple myeloma who died of liver failure 7.5 months after initial diagnosis. Postmortem liver biopsy revealed diffuse CD3-expressing plasma cell infiltration and eosinophilic amorphous material deposition which was considered as light chain deposits. T cell receptor-gamma rearrangement was not detected in liver biopsy sections using the polymerase chain reaction despite CD3 positivity. To our knowledge, this is the first report of CD3-expressing plasma cell infiltration in tissue sections. The discordance between the phenotype and the genotype suggests a partial activation of genes encoding the T cell antigens by the transforming event. We also concluded that CD3 positivity was associated with short survival, which is consistent with previous data.     

Hugging balloon angioplasty of right coronary artery

We report a case of “hugging balloon” dilatation of a giant right coronary artery using two dilatation catheters, a balloon “on a wire” and a balloon “rapid exchange” systems via a single guiding catheter. The necessity of larger PTCA balloon catheter (>4.0 mm) was stressed.     

Determination of iodine concentration in urine by isotope dilution analysis and thyroid volume of school children in the west coast of Turkey after mandatory salt iodization

OBJECTIVE: This study was designed to evaluate iodine deficiency status in children 6-12 years in the west coast (Aegean Region) of Turkey after 5 years of mandatory iodine prophylaxis. A total of 2300 children from 72 populations (rural and urban area) were evaluated with urinary iodine excretion and thyroid volume. DESIGN: Cross-sectional, observational study designed and performed according to surveillance methods for iodine deficiency disease (IDD) prevalence recommended by WHO/UNICEF/ICCIDD. SUBJECTS: The study population consisted of 2300 school children age ranging from 6 to 12 years. The children were selected by multiple stage randomization from 91 primary schools of 76 zones (91 clusters). Information about the use of iodized salt was obtained from the families. MEASUREMENTS: Data on the following were collected: birth date, sex, weight, height, thyroid size by palpation and ultrasonography; and urinary iodine by isotope dilution analysis method. Thyroid volumes above 97th percentile according to the WHO/ICCIDD by age and body surface area (BSA) were accepted as goitre. RESULTS: Iodized salt consumption was 51.7%. The prevalence of goitre determined by palpation was 12.1% and by ultrasound based on BSA and age were 9.8% and 5.5%, respectively. Median urinary iodine was 53 (2-142) microg/l. CONCLUSION: Mild to severe degree of iodine deficiency was detected in the west coast of Turkey.     

Relationship between serum leptin level and disease activity in patients with systemic sclerosis

To determine the relationship between serum leptin levels and disease activity in systemic sclerosis (SSc). A total of 60 subjects (30 controls and 30 patients) were included. The inflammatory markers and leptin levels were evaluated and body mass index (BMI) was measured for both groups. The assessment of the skin involvement was performed based on the modified Rodnan skin score (mRSS). Disease activity was evaluated according to the Valentini scleroderma disease activity index. There was a significant difference between the patient and control groups in terms of BMI (p?<?0.05); however there was no difference with regards to age and gender (p?>?0.05). Valentini scores and mRSS were determined to be significantly higher in active patients (n?=?14) than in inactive patients (n?=?16) (p?<?0.05). No significant difference was determined between groups in terms of leptin levels (p?>?0.05). However, leptin levels were significantly lower in active patients than in inactive patients (p?<?0.05). We found a significant positive correlation between serum leptin and BMI (p?<?0.05), and leptin and serum C3 levels (p?<?0.05); no relationship was detected between leptin and other parameters. Leptin can be used as an activity marker in SSc. Further studies, including larger series, should be carried out to clarify this relationship.
