Abstract

Although repetitive Transcranial Magnetic Stimulation (rTMS) is frequently used to examine emotional changes in healthy volunteers, it remains largely unknown how rTMS is able to influence emotion.We carried out a sham-controlled single-blind crossover study using fMRI, we examined in 20 right-handed healthy female volunteers whether a single high frequency (HF)-rTMS session applied to the left dorsolateral prefrontal cortex (DLPFC) could influence emotional processing while focussing on blocks of positively and negatively valenced baby faces. A single HF-rTMS session selectively influenced the processing of positively and negatively valenced baby faces. In essence, our results indicate that the effects of one left-sided HF-rTMS sessions results in improved processing of positive emotions and reduced negative emotional processing in never depressed female subjects

Abstract

Postmastectomy edema is a current complication after axillary lymph node dissection in cases of breast cancer treatment. Staging is important in order to select those patients who can benefit from complex physical therapy (CPT). Different imaging techniques can be used to evaluate the edema. Ultrasonography (US) is a harmless, cheap, and easily applicable technique to visualize the dermal and subcutaneous tissue, but interpretation of the obtained images is not always evident. The aim of this study was to compare ultrasound images of irreversible edema with tissue histology, magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS). Ultrasonographic images of the edematous dermis show an homogeneous hypoechogenic dermal layer that appears on tissue histology to be less compact, due to the excess of fluid in the interstitium separating the collagen fibres and making it more transparent on light microscopy. MRI of the dermis gives a hyperintense signal, indicating the presence of fluid. In the subcutis, increase of the adipose tissue could be observed on US, MRI, and tissue histology. In the case of lymphedema, the area and perimeter of fat cells is significantly (p < 0.05) increased. Hypoechogenic areas near the muscle fascia are registrated on US corresponding with epifascial fluid on MRI, and hyperechogenic branches are embedded within the adipose tissue, on tissue histology seen as large fibrotic septa enclosing adipose cells. MRI has a honeycomb picture corresponding with fluid bound to fibrosis. © Mary Ann Liebert, Inc., SCOPUS: ar.j, info:eu-repo/semantics/published

Author

Willekens, Inneke, Vandenbroucke, Frederik, Sennesael, Jacques, de Mey, Johan, Willekens, Inneke, Vandenbroucke, Frederik, Sennesael, Jacques, and de Mey, Johan

Abstract

The imaging findings of amyloidosis are nonspecific and diverse due to its association with various chronic diseases such as multiple myeloma. We report a case of gastrointestinal amyloidosis presenting as enterocolitis on a contrast enhanced CT scan of the abdomen.

Abstract

Background: Both hepatic arterial infusion (HAI) of chemotherapy and cetuximab (CET) have interesting activity for the treatment of colorectal cancer liver metastases (CRC-LM). Patients and Methods: Intravenous CET with HAI oxaliplatin (OXA) or i.v. Irinotecan (IRI) followed by HAI of infusion of folic acid modulated 5-fluorouracil 5-FU/l-FA was administered to patients (pts) with CRC-LM who had failed at least one line of prior chemotherapy. Results: Eight pts received i.v. CET with HAI-OXA (5 pts) and i.v.-IRI (3 pts) and HAI-S-FU/I-FA. Adverse events: repeated grade 3 skin toxicity (1 pt), abdominal pain with elevated liver enzymes and asthenia (2 pts), duodenal ulcer (2 pts) with catheter migration and intestinal bleeding (1 pt), reversible interstitial pneumonitis (1 pt), and cystic bile duct dilatation (2 pts) with arteriobiliary fistulisation (1 pt). A partial response was documented in 5 pts (62%). The median time to progression was 8.7 months (95% confidence interval 8-14 months). Conclusion: Intravenous administration of CET with HAI of chemotherapy is feasible and has promising activity but is associated with specific toxicity., SCOPUS: ar.j, info:eu-repo/semantics/published

312. Ileocolic invagination as a complication of a cecal adenocarcinoma

Author

Abstract

Ileocolic invagination in the adult may be caused by adenocarcinoma and lead to intestinal obstruction. We report a case of a cecal adenocarcinoma that was complicated by an ileocolic invagination in a 38 year old female, diagnosed on a contrast enhanced CT scan of the abdomen and highlights the importance of contrast enhanced CT for diagnosis of ileocolic invagination.

320. Aortoesophageal fistula following endovascular exclusion of a thoracic aneurysm

Author

Martens, Koen, Van den Brande, Pierre, De Mey, Johan, Everaert, Hendrik, Delvaux, Georges, Martens, Koen, Van den Brande, Pierre, De Mey, Johan, Everaert, Hendrik, and Delvaux, Georges

Abstract

The aim of this study was to report a case of aortoesophageal fistula following endovascular exclusion of a thoracic aneurysm, treated conservatively with fatal outcome. Endovascular exclusion of a thoracic aneurysm was performed in a 64-year-old female patient. Three months later the diagnosis of an aortoesophageal fistula was made and minimal surgery (cervicotomy and jejunostomy) was performed, combined with antibiotherapy and catheter flushing of the infected excluded aneurysm thrombus. The patient died in septic shock 9 weeks later. As reported, following conventional thoracic aortic aneurysm surgery, endovascular stenting of the thoracic aorta can be complicated by aortoesophageal fistula. Management should be surgical, since the outcome under conservative management seems invariably fatal. However, it looks as if the poor condition of these patients may not permit open surgical treatment., SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract

Objective: To assess CT features of the sternoclavicular joint (SCJ) and first costochondral junction in asymptomatic patients.Materials and Methods: In 66 patients transverse and coronal oblique high-resolution multiple detector CT images of the SCJ and first costochondral junction were obtained. Images were reviewed by consensus of two radiologists. Joint space width was measured at three levels, and osteophytes, geodes, and erosions were evaluated. Variants and degree of ossification were noted. Statistical analysis consisted of Shapiro-Wilk test, Pearson's test, and paired sample t test.Results: There were 34 men and 32 women with a mean age of 60 years (age range, 17-98 years). The width of the joint spaces showed a normal distribution. There was no significant difference between the left and right sides. On coronal images the joint space was wider superiorly and on transverse images posteriorly. There was a trend toward decreasing joint space with age, although it did not reach significance (p > 0.05). Clavicular osteophytes were seen in 16 out of 66 patients (24 %) and sternal osteophytes in 16 out of 66 patients. Clavicular geodes were seen in 10 out of 66 patients (15 %) and sternal geodes in 14 out of 66 patients (14 %). No erosions were seen. Clefts of the first costochondral junction were seen in 31 out of 66 patients (47 %).Conclusion: In asymptomatic patients, there is no significant asymmetry of the SCJ. The joint spaces did not significantly decrease with age, although such a trend could be observed. Pronounced joint space narrowing with large geodes and osteophytes was not seen. Clefts of the first costochondral junction are common and not significant. [ABSTRACT FROM AUTHOR]

336. FDG accumulation in inguinal herniation mimicking metastatic disease

Author

Muylle, Kristoff, Everaert, Hendrik, De Mey, Johan, Lahoutte, Tony, Franken, Philippe, Bossuyt, Audrey, Muylle, Kristoff, Everaert, Hendrik, De Mey, Johan, Lahoutte, Tony, Franken, Philippe, and Bossuyt, Audrey

Abstract

Positron emission tomography (PET) using fluorodeoxy-glucose (FDG) plays an important role in the management of oncologic diseases. Interpretation of the FDG-PET data requires a profound knowledge of the normal variety of FDG biodistribution and of the different pitfalls that may mimic additional localizations of disease. The authors report a unique case of focal increased FDG activity resulting from intestinal uptake in an inguinal herniation., SCOPUS: ar.j, info:eu-repo/semantics/published
