Comparison of neurological status in patients treated in a stroke unit with those treated in classical care model

140 patients with stroke (69 men and 71 women) aged 71.7 +/- 12.4 treated in the general neurology were compared with 102 patients (46 men, 56 women) aged 71.5 +/- 11.2 treated in the stroke unit during the period 1.11.95 to 31.10.97. Neurological status and state of environmental dependency during the discharge time were similar in both groups, but the state of motor performance was significantly better in the group of patients treated in the stroke unit. In the stroke unit collaboration between nurses and rehabilitants makes it possible to increase the time of rehabilitation and to introduce the elements of exercises which can be done by patients under control of nurse.     

Effect of peritoneal fluid from patients with mild and severe endometriosis on endometrial stromal cell proliferation

The aim of this study was to evaluate and compare the mitogenic effect of peritoneal fluid (PF) from women with mild and severe endometriosis on the endometrial stromal cell proliferation. Increasing concentrations of PF from women with and without mild or severe endometriosis were added to primary endometrial stromal cell cultures and³H-thymidine incorporation was used to assess DNA synthesis in these cultures. PF from women with mild endometriosis induced a statistically significant dose-dependent increase in stromal cell thymidine uptake ranged from 5.8 to 14.5 fold, whereas PF from women with severe endometriosis produced an average 51% inhibition of stromal cell proliferation of compared with cells exposed to non-endometriosis PF or exposed to nutrient medium supplemented with 2.5% calf serum alone. PF samples from patients with stage I endometriosis induced a statistically dose-dependent increase in stromal cell proliferation, whereas PF from patients with stage IV endometriosis caused a significant inhibition.     

Do you mean me? Communicative intentions recruit the mirror and the mentalizing system

Being able to comprehend communicative intentions and to recognize whether such intentions are directed toward us or not is extremely important in social interaction. Two brain systems, the mentalizing and the mirror neuron system, have been proposed to underlie intention recognition. However, little is still known about how the systems cooperate within the process of communicative intention understanding and to what degree they respond to self-directed and other-directed stimuli. To investigate the role of the mentalizing and the mirror neuron system, we used functional magnetic resonance imaging with four types of action sequence: communicative and private intentions as well as other-directed and self-directed intentions. Categorical and functional connectivity analyses showed that both systems contribute to the encoding of communicative intentions and that both systems are significantly stronger activated and more strongly coupled in self-directed communicative actions.     

Impact of scanning density on spectral domain optical coherence tomography assessments in neovascular age‐related macular degeneration

Purpose: To determine the effect of optical coherence tomography (OCT) B‐scan density on the qualitative assessment of neovascular age‐related macular degeneration (AMD). Methods: Data were collected from 59 patients imaged with Topcon 3D OCT‐1000 (128 B‐scans × 512 A‐scans). Custom software was used to generate less dense subsets of scans: 1/16 (eight B‐scans), 1/8 (16 B‐scans), 1/4 (32 B‐scans) and 1/2 (64 B‐scans). At each B‐scan density, scans were assessed for cystoid spaces, subretinal fluid (SRF), subretinal tissue (SRT) and pigment epithelium detachment (PED). For each sampling density, sensitivity, specificity and predictive values were calculated using the full volume scan (128 B‐scans) as the reference standard. Results: For cystoid spaces, the detection sensitivity was 76.3% at 1/16 density; this rose to 89.5% with a 1/4 density. For SRF, the detection sensitivity was 75.0% at a 1/16 density; this increased to 91.1% with 1/4 density. For PED, even at the lowest sampling density (1/16) the detection sensitivity was 86.4%; this rose to 94.9% at 1/4 density. For SRT, detection sensitivity at a 1/16 density was 64.7% and only rose above 90% with the densest sampling subset (1/2). Conclusions: Use of scanning protocols with reduced sampling densities resulted in decreased detection of key features of neovascular AMD; despite this, a sampling density reduced to 1/4 appeared to allow accurate assessment for most features. Current management of neovascular AMD is dependent on qualitative assessment of OCT images; with the recent proliferation of OCT systems, optimization and standardization of scanning protocols may be of value.     

Lupus attributable to anti-TNF therapy and revealed by interstitial granulomatous dermatitis

Interstitial granulomatous dermatitis belongs to the group of aseptic cutaneous granulomas. It is a histopathological entity encountered in various pathological situations, such as polyarthritis including rheumatoid arthritis, but also systemic lupus erythematosus. It may also occur after systemic administration of medication, thus representing a drug-induced, interstitial granulomatous outbreak. This has recently been described after anti-TNF therapy was taken. We are reporting the case of a patient treated using adalimumab for rheumatoid arthritis and having developed interstitial granulomatous dermatitis during treatment, which revealed lupus erythematosus attributable to the biotherapy. The clinical appearance of interstitial granulomatous dermatitis can vary, and the diagnosis is confirmed by anatomo-pathological examination. Drug-induced interstitial granulomatous outbreaks have specific histological criteria, and secondary cases involving anti-TNF medication have been described. Cases of lupus attributable to anti-TNF therapy have also been described, and they have specific biological characteristics. Like idiopathic lupus, they may be associated with interstitial granulomatous dermatitis, but the association of an anti-TNF-induced lupus and this type of granulomatous has not, to our knowledge, been described before. We are reporting one case, which emphasises the importance of carrying out a complete and systematic aetiological assessment for all cases of interstitial granulomatous dermatitis, including where there is systemic disease or following medical treatment, either of which may provide an evident cause for the granulomatosis. In particular, the outbreak of interstitial granulomatous dermatitis during anti-TNF treatment should lead to screening for a drug-induced lupus, which would require the patient to stop such treatment.     

Non-Epstein–Barr virus associated lymphoepithelioma-like carcinoma of the esophagogastric junction with microsatellite instability,K-ras wild type

A 60-year-old male was admitted to our hospital for gastric cancer. Considering his general condition, total gastrectomy and dissection of regional lymph nodes were performed. Macroscopically, a 45 mm × 20 mm × 10 mm-sized, ulcero-infiltrative tumor located in the esophagogastric junction was described. Microscopically, the tumor consisted of a poorly differentiated adenocarcinoma intermingled with dense lymphoid infiltration predominantly composed of T-cell lymphocytes. The tumor cells infiltrated the submucosa, muscularis and subserosal layers of the stomach, respectively the esophageal adventitia. No metastases were noticed in the 58 regional lymph nodes. Based on the histopathological features, the diagnosis was lymphoepithelioma-like carcinoma, pT3N0 stage. In situ hybridization for Epstein–Barr virus showed no nuclear signal in tumor cells. The p53 expression was observed in fewer than 10% of the tumor cells. Real-time PCR analysis showed microsatellite instability without K-ras mutation in codon 12. No recurrences or metastases were reported 6 months after surgical intervention. No adjuvant therapy was performed.
