Difficulty has been encountered when trying to identify ante mortem prognostic indicators for dogs with meningoencephalitis of unknown etiology (MUE). Identifying MRI imaging parameters associated with prognosis may impact treatment decision-making for clinician and owner. Our hypotheses for this retrospective cohort study are that dogs diagnosed with MUE that had midline shift on brain MRI would have a poorer survival compared to dogs without midline shift; and that younger age, lower weight, and low cerebrospinal fluid (CSF) cell count would be correlated with improved survival...

BACKGROUND: Achalasia is extremely rare in infants. CASE CHARACTERISTICS: We report three infants of age 9, 7 and 12 months, who presented with recurrent non-bilious vomiting, repeated chest infection and severe failure to thrive. Diagnosis of achalasia cardia was confirmed on contrast-swallow study. Hellers cardiomyotomy with fundoplication led to complete symptomatic relief, and weight-gain on follow-up. MESSAGE: Achalasia cardia is often misdiagnosed as gastroesophageal reflux disease which leads to significant delay in diagnosis and increased morbidity...

Melanocytic matrical carcinoma is a very uncommon malignant neoplasm with follicular differentiation. The lesion often presents as a solitary nodule on sun-exposed skin of elderly patients. Histopathologically, it is characterized by proliferation of atypical matrical cells admixed with an increased number of melanocytes, and some atypical matrical cells may have cytoplasmic pigment. When melanocytic proliferation or melanin pigment is prominent, melanocytic metrical carcinoma can mimic melanoma. Here, we present a novel case of melanocytic matrical carcinoma mimicking melanoma in an 80-year-old man with our findings in histopathologic and immunohistochemical study...

BACKGROUND: Per-oral endoscopic myotomy (POEM) has become an accepted treatment for patients with achalasia. Despite its excellent efficacy rate of greater than 80%, a small percentage of patients remain symptomatic postprocedure. Limited data exist as to the best management for recurrence of symptoms after POEM. We present the first international, multicenter experience on the efficacy and safety of a repeat POEM in the management of achalasia. METHODS: Patients who underwent a redo POEM from 15 centers in 9 countries were included in a dedicated registry...

The treatment for achalasia changed dramatically after the introduction of minimally invasive surgery. Since 1991, laparoscopic Heller myotomy (LHM) has replaced pneumatic dilatation (PD) as the primary form of treatment in many centers. Over time, PD became safer, and eventually endoscopic experts were able to perform an endoscopic myotomy via a per oral endoscopic myotomy (POEM). This article reviews the advantages and disadvantages of each technique. Ultimately, the best outcomes are obtained by a multidisciplinary team that can tailor a specific treatment to each individual patient...

Elevated basal serum tryptase levels are present in 4-6% of the general population, but the cause and relevance of such increases are unknown. Previously, we described subjects with dominantly inherited elevated basal serum tryptase levels associated with multisystem complaints including cutaneous flushing and pruritus, dysautonomia, functional gastrointestinal symptoms, chronic pain, and connective tissue abnormalities, including joint hypermobility. Here we report the identification of germline duplications and triplications in the TPSAB1 gene encoding α-tryptase that segregate with inherited increases in basal serum tryptase levels in 35 families presenting with associated multisystem complaints...

Circulating tumor cell (CTC) number measured with the CellSearch assay is prognostic for survival in metastatic castration-resistant prostate cancer before and after therapy. Using a standard operating protocol for sample collection, processing, and analysis, we compared detection rates of CellSearch performed using US Food and Drug Administration-cleared methodology with a second positive selection assay, AdnaTest, and a nonselection polymerase chain reaction (PCR)-based (direct detection PCR [DDPCR]) assay in 55 blood samples from 47 men with progressive metastatic castration-resistant prostate cancer...

OBJECTIVE: Postmenopausal bleeding must always be evaluated to rule out endometrial carcinoma, although there are many benign etiologies. There have been rare reports of premenopausal bleeding with interferon beta-1b, used to treat multiple sclerosis, but no prior reports in postmenopausal women. METHODS: Literature searches were performed using PubMed and Medline for articles with content related to premenopausal and postmenopausal bleeding while taking interferon beta-1b...

Lung M2 macrophages are regulators of airway inflammation, associated with poor lung function in allergic asthma. Previously, we demonstrated that IL-4-induced M2 gene expression correlated with tyrosine phosphorylation of the insulin receptor substrate (IRS)-2 in macrophages. We hypothesized that negative regulation of IRS-2 activity following IL-4 stimulation is dependent upon serine phosphorylation of IRS-2. Herein, we describe an inverse relationship between tyrosine phosphorylation (pY) and serine phosphorylation (pS) of IRS-2 following IL-4 stimulation...

BACKGROUND: Cells of the vascular system release spherical vesicles, called microparticles, in the size range of 0.1-1μm induced by a variety of stress factors resulting in variable concentrations between health and disease. Furthermore, microparticles have intercellular communication/signaling properties and interfere with inflammation and coagulation pathways. Today's most used analytical technology for mecroparticle characterization, flow cytometry, is lacking sensitivity and specificity, which might have led to the publication of contradicting results in the past...

This study determined the effects of nitrite on different life stages of the Amazon river prawn Macrobrachium amazonicum. Prawns of each life stage (postlarvae, juveniles and adults) were stocked in 24 experimental units (n = 10 prawns), under a complete randomized design. Individuals were exposed to nitrite (0, 1, 2, 4, 8 and 16 mg L(-1)). The median lethal concentration after 96 h (96 h LC50) was calculated through the Weibull I. The mortality results showed that M. amazonicum is slightly less tolerant to nitrite than other species of Macrobrachium...

Objective: Subjective cognitive decline is controversially discussed as early notable sign of future dementia in the literature. Therefore, we aimed to investigate whether SCD predicts dementia in a sample of cognitively unimpaired older individuals (75+). Methods: 595 cognitively unimpaired individuals who participated in the Leipzig Longitudinal Study of the Aged (LEILA75+) were regularly interviewed and cognitively tested over 8 years. Cox regression analyses were used to determine the association of SCD and development of dementia...

Goji berries (Lycium barbarum L.) have been known to contain strikingly high levels of zeaxanthin, while the physical deposition form and bioaccessibility of the latter was yet unknown. In the present study, we associated ripening-induced modifications in the profile of carotenoids with fundamental changes of the deposition state of carotenoids in goji berries. Unripe fruit contained common chloroplast-specific carotenoids being protein-bound within chloroplastidal thylakoids. The subsequent ripening-induced transformation of chloroplasts to tubular chromoplasts was accompanied by an accumulation of up to 36mg/100g FW zeaxanthin dipalmitate and further minor xanthophyll esters, prevailing in a presumably liquid-crystalline state within the nano-scaled chromoplast tubules...

BACKGROUND: Peroral endoscopic myotomy (POEM) is an emerging procedure in the treatment of esophageal achalasia, a primary motility disorder. However, the long-term outcome of POEM in patients, who have previously undergone a Heller myotomy, is unknown. METHODS: Using a local database, we identified patients with esophageal achalasia, who underwent POEM. We compared patients with a previous Heller myotomy to those, who had received none or only non-surgical therapy prior to the POEM procedure...
