Agitation and Sugar Craving Related to Epilepsy Seizure.

INTRODUCTION: Epilepsy is a chronic central nervous system disorder characterized by the recurrence of unprovoked seizures and can affect people of all ages. Seizure symptoms can vary widely in patients. Many papers have been published about agitation and epileptic seizures, but almost nothing about sugar cravings and agitation related to epilepsy. The purpose of this case report is to shed light on possibly a hidden symptom within the epilepsy field, in fact sugar cravings. Case presentation. A 12-year-old boy was referred to the children and adolescent psychiatric outpatient clinic with suspicion of ADHD. The boy has struggled with anxiety, concentration, and impulsivity. Because of intense agitation and sugar cravings, the patient was referred to EEG. The EEG shows pathological activity with bilatero-temporal to central epileptiform activity, not synchronized. After pathological EEG findings, the patient started treatment with Lamotrigine. Great improvement when it comes to agitation, moodiness, and reduction of sugar craving after starting with Lamotrigine. CONCLUSION: We consider inexplicable behavior or symptoms such as agitation and sugar craving may be related to epilepsy seizure. Therefore, it is important that these patients should be examined more closely with EEG to confirm or deny epilepsy.

Sitagliptin Modulates the Response of Ovarian Cancer Cells to Chemotherapeutic Agents.

The strong association between diabetes mellitus type 2 and cancer is observed. The incidence of both diseases is increasing globally due to the interaction between them. Recent studies suggest that there is also an association between cancer incidence and anti-diabetic medications. An inhibitor of dipeptidyl-peptidase 4 (DPP-4), sitagliptin, is used in diabetes treatment. We examined the influence of sitagliptin alone or in combination with a cytostatic drug (paclitaxel) on the development of epithelial ovarian cancer cells and the process of metastasis. We examined migration, invasiveness, apoptosis, and metalloproteinases (MMPs) and their inhibitors' (TIMPs) production in two human ovarian cancer cell lines. Sitagliptin induced apoptosis by caspase 3/7 activation in paclitaxel-treated SKOV-3 and OVCAR-3 cells. Sitagliptin maintained paclitaxel influence on ERK and Akt signaling pathways. Sitagliptin additionally reduced migration and invasiveness of SKOV-3 cells. There were distinct differences of metalloproteinases production in sitagliptin-stimulated ovarian cancer cells in both cell lines, despite their identical histological classification. Only the SKOV-3 cell line expressed MMPs and TIMPs. SKOV-3 cells co-treated with sitagliptin and paclitaxel decreased concentrations of MMP-1, MMP-2, MMP-7, MMP-10, TIMP-1, TIMP-2. The obtained data showed that sitagliptin used with paclitaxel may be considered as a possibility of pharmacological modulation of intracellular transmission pathways to improve the response to chemotherapy.

Role of Telemedicine in Multidisciplinary Team Meetings.

We reviewed the role of telemedicine in multidisciplinary team (MDT) meetings, which play an important role in the provision of effective and tailored patient care in diverse clinical settings. This article is based on conducted search in PubMed. Search terms included "telemedicine," "multidisciplinary team," and "(telemedicine) and (multidisciplinary team)." Telemedicine provides an important advantage in the provision of MDT meeting comparing with traditional settings. Those include improved access to and collaboration of medical experts. This resulted in increased levels of medical competence and improved provisions of diagnosis, treatment, and follow-up to patients irrespective of location.

Exenatide modulates expression of metalloproteinases and their tissue inhibitors in TNF-α stimulated human retinal pigment epithelial cells.

BACKGROUND: Diabetic retinopathy (DR) is one of the most common complications of diabetes and the leading cause of acquired blindness in adults. In diabetic patients hyperglycemia induces complex metabolic abnormalities affecting retinal homeostasis, and promotes retinal inflammation and angiogenesis. Incretin mimetic drugs such exenatide, are a relatively new group of drugs used in the treatment of diabetes. We investigated the potential direct effects of exenatide on human retinal pigment epithelium (HRPE). METHODS: cAMP production was measured after stimulation of HRPE cells with GLP-1 and exenatide. Intracellular signaling pathways were also examined. HRPE cells were stimulated with TNF-α and subsequently incubated with exenatide. The concentration of metalloproteinases, MMP-1, MMP-2 and MMP-9, and tissue inhibitors of metalloproteinases, TIMP-1, TIMP-2, and TIMP-3 were evaluated. Viability, cytotoxicity and caspase 3/7 activation were determined. Activity of dipeptidyl peptidase-4 (DPP-4), an enzyme involved in GLP-1 inactivation, was also determined. RESULTS: Both GLP-1 and exenatide stimulation in HRPE cells caused no effect in cAMP levels suggesting alternative signaling pathways. Signaling pathway analysis showed that exenatide reduced phosphorylation of Akt-Ser473, PRAS40, SAPK/JNK, Bad, and S6 proteins but not Akt-Thr308. Exenatide also decreased MMP-1, MMP-9, and TIMP-2 protein levels whereas MMP-2 level in HRPE cells was increased. Finally, we show that exenatide decreased the activity of DPP-4 in TNF-α stimulated HRPE cells. CONCLUSIONS: These findings indicate that exenatide modulates regulation of extracellular matrix components involved in retinal remodeling.

Complete Routine Remote Digital Pathology Services.

BACKGROUND: Validation studies in digital pathology addressed so far diverse aspects of the routine work. We aimed to establish a complete remote digital pathology service. METHODS: Altogether 2295 routine cases (8640 slides) were reported in our studies on digital versus microscopic diagnostics, remote reporting, diagnostic time, fine-needle aspiration cytology (FNAC) clinics, frozen sections, and diagnostic sessions with residents. The same senior pathologist was involved in all studies. Slides were scanned by ScanScope AT Turbo (Aperio). Digital images were accessed through the laboratory system (LS) on either 14" laptops or desktop computers with double 23" displays for the remote and on-site digital reporting. Larger displays were used when available for remote reporting. First diagnosis was either microscopic, digital, or remote digital only (6 months washout period). Both diagnoses were recorded separately and compared. Turnaround was measured from the registration to sign off or scanning to diagnosis. A diagnostic time was measured from the point slides were made available to the point of diagnosis or additional investigations were necessary, recorded independently in minutes/session, and compared. Jabber Video (Cisco) and Lync (Microsoft) were interchangeably used for the secure, video supervision of activities. Mobile phone, broadband, broadband over Wi-Fi, and mobile broadband were tested for internet connections. Nine autopsies were performed remotely involving three staff pathologists, one autopsy technician, and one resident over the secure video link. Remote and on-site pathologists independently interpreted and compared gross findings. Diverse benefits and technical aspects were studied using logs or information recorded in LS. Satisfaction surveys on diverse technical and professional aspects of the studies were conducted. RESULTS: The full concordance between digital and light microscopic diagnosis was 99% (594/600 cases). A minor discordance, without clinical implications, was 1% (6/600 cases). The instant upload of digital images was achieved at 20 Mbps. Deference to microscopic slides and rescanning were under 1%. Average turnaround was shorter and percentage of cases reported up to 3 days higher for remote digital reporting. Larger displays improved the most user experience at magnifications over ×20. A digital diagnostic time was shorter than microscopic in 13 sessions. Four sessions with shorter microscopic diagnostic time included more cases requiring extensive use of magnifications over ×20. Independent interpretations of gross findings between remote and on-site pathologists yielded full agreement in the remote autopsies. Delays in reporting of frozen sections and FNAC due to scanning were clinically insignificant. Satisfaction levels with diverse technical and/or professional aspects of all studies were high. CONCLUSIONS: Complete routine remote digital pathology services are found feasible in hands of experienced staff. The introduction of digital pathology has improved provisions and organizations of our pathology services in histology, cytology, and autopsy including teaching and interdepartmental collaboration.

Exenatide modulates metalloproteinase expression in human cardiac smooth muscle cells via the inhibition of Akt signaling pathway.

BACKGROUND: Incretin analogue drugs, a FDA-approved treatment in diabetes, has been tested for its therapeutic properties as modulators of atherosclerosis. We investigated the effects of incretin drugs on the modulation of gene expression and protein levels of matrix metalloproteinases (MMPs) as well as their inhibitors - tissue inhibitors of metalloproteinases (TIMPs) in coronary artery smooth muscle cells (hCASMC) in the context of atherosclerotic plaque formation and inflammation. METHODS: TNFα-stimulated hCASMC were treated with Glucagon-like Peptide 1 (GLP-1) (10nM and 100nM) and Exendin-4 (1nM and 10nM). Messenger RNA (mRNA) levels and protein concentrations of MMP-1, MMP-2, MMP-9 and TIMP-1, TIMP-2 were measured and the effects on extracellular matrix turnover under TNFα-mediated microenvironment were evaluated. Intracellular signaling pathways were also examined. RESULTS: Our experiments reveal that GLP-1 receptor agonists downregulate the expression of MMP-1, MMP-2, MMP-9 in hCASMC under TNFα mediated inflammatory conditions. Signaling pathway analysis show that GLP-1 receptor agonists induced inhibition of AKT-Thr308 phosphorylation, PRAS40 and S6 proteins but not AKT-Ser473. CONCLUSIONS: These findings indicate that GLP-1 receptor agonists modulate the expression of MMPs through inhibition of AKT-Thr308 phosphorylation in hCASMC. These results suggest a possible role of incretin analogue drugs in therapy of coronary atherosclerosis.

Remote autopsy services: A feasibility study on nine cases.

Introduction We have conducted a feasibility study on remote autopsy services in order to increase the flexibility of the service with benefits for teaching and interdepartmental collaboration. Methods Three senior staff pathologists, one senior autopsy technician and one junior resident participated in the study. Nine autopsies were performed by the autopsy technician or resident, supervised by the primary pathologist, through the secure, double encrypted video link using Jabber Video (Cisco) with a high-speed broadband connection. The primary pathologist and autopsy room each connected to the secure virtual meeting room using 14″ laptops with in-built cameras (Hewlett-Packard). A portable high-definition web camera (Cisco) was used in the autopsy room. Primary and secondary pathologists independently interpreted and later compared gross findings for the purpose of quality assurance. The video was streamed live only during consultations and interpretation. A satisfaction survey on technical and professional aspects of the study was conducted. Results Independent interpretations of gross findings between primary and secondary pathologists yielded full agreement. A definite cause of death in one complex autopsy was determined following discussions between pathologists and reviews of the clinical notes. Our satisfaction level with the technical and professional aspects of the study was 87% and 97%, respectively. Discussion Remote autopsy services are found to be feasible in the hands of experienced staff, with increased flexibility and interest of autopsy technicians in the service as a result.

Exenatide modulates tumor-endothelial cell interactions in human ovarian cancer cells.

Diabetes and cancer are prevalent diseases whose incidence is increasing globally. Diabetic women have a moderate risk increase in ovarian cancer, suggested to be due to an interaction between these two disorders. Furthermore, patients manifesting both diseases have associated worse prognosis, reduced survival and shorter relapse-free survival. According to current recommendations, incretin drugs such as Exenatide, a synthetic analog of Exendin-4, and Liraglutide are used as therapy for the type 2 diabetes (T2D). We studied the effects of GLP-1 and Exendin-4 on migration, apoptosis and metalloproteinase production in two human ovarian cancer cells (SKOV-3 and CAOV-3). Exendin-4 inhibited migration and promoted apoptosis through caspase 3/7 activation. Exendin-4 also modulated the expression of key metalloproteinases (MMP-2 and MMP-9) and their inhibitors (TIMP-1 and TIMP-2). Vascular endothelial cells, which contribute to the formation and progression of metastasis, were also analyzed. TNF-α-stimulated endothelial cells from iliac artery after Exendin-4 treatment showed reduced production of adhesion molecules (ICAM-1 and VCAM-1). Additionally, incretin treatment inhibited activation of apoptosis in TNF-α-stimulated endothelial cells. In the same experiment, MMPs (MMP-1 and MMP-9), which are relevant for tumor development, were also reduced. Our study demonstrated that incretin drugs may reduce cancer cell proliferation and dissemination potential, hence limiting the risk of metastasis in epithelial ovarian cancer.

Invasive Esophageal Candidiasis with Chronic Mediastinal Abscess and Fatal Pneumomediastinum.

BACKGROUND Invasive candidiasis is a potential problem for patients receiving long-term immunosuppressive treatment. Psoriatic arthritis is one of many chronic diseases that can be successfully treated with immunosuppressive drugs, in spite of a documented and accepted risk for infectious complications. Critical awareness of possible infection must be part of the surveillance of such patients. CASE REPORT This is the case of a 68-year-old Norwegian male, treated with long-term immunosuppression for psoriatic arthritis, hospitalized with acute subcutaneous and mediastinal emphysema of unknown cause. He died of acute respiratory failure with circulatory collapse shortly after admission. The autopsy revealed mediastinal and subcutaneous emphysema and a mediastinal abscess containing Candida with probable entrance from the esophagus. CONCLUSIONS We consider invasive candidiasis of the esophagus to be the cause of both the chronic abscess and the acute mediastinal emphysema. This case illustrates the importance of awareness of invasive candidiasis as a possible complication in a patient with long-term immunosuppression.

Sudden death associated with silent myocardial infarction in a 35-year-old man: a case report.

BACKGROUND: Silent myocardial infarction relates to the absence of symptoms usually associated with myocardial ischemia. It has been estimated that silent myocardial infarction can occur in 2-4 % of young adult asymptomatic men. A majority of patients without an initially apparent cause of sudden death have been found at autopsy to have had significant coronary heart disease, including old, undetected myocardial infarction. Cases of sudden death in young men with unrecognized silent myocardial ischemia seem to be underreported, however. CASE PRESENTATION: A 35-year-old Norwegian man without a previous medical history died suddenly without preceding symptoms of coronary ischemia. Apart from elevated lactate, his laboratory test results were within normal limits. An autopsy revealed advanced coronary artery thrombosis of the left anterior descending branch with an extensive, partly organized myocardial infarction. The results of toxicological examinations of peripheral blood were negative for usual narcotics and alcohol. CONCLUSIONS: Sudden, unexpected death due to myocardial infarction can occur even at a young age in patients without known coronary heart disease.

Effects of incretin agonists on endothelial nitric oxide synthase expression and nitric oxide synthesis in human coronary artery endothelial cells exposed to TNFα and glycated albumin.

BACKGROUND: There have been a number of beneficial effects of incretin agonists on the cardiovascular system. Glycated albumin (GA) and tumor necrosis factor (TNFα) may lead to endothelial dysfunction. Due to reports of cardioprotective effects of incretin agonist, we wanted to determine if GLP-1 and exendin-4 can reverse diminished production of nitric oxide (NO) after treatment with TNFα and GA. The objective of our experiment was to study the interaction between incretin agonists and proinflammatory substances like TNFα and GA on production of NO in HCAEC. METHODS: Human vascular endothelial cells from the coronary artery (HCAEC) were used. The mRNA expression and protein level of endothelial nitric oxide synthase (eNOS) and inducible (iNOS) were quantified. NO production was measured in cells using DAF-FM/DA and flow cytometry. RESULTS: TNFα (10 ng/mL) decreased eNOS: mRNA by 90% and protein level by 31%. TNFα also decreased NO by 33%. GA (500 µg/mL) neither affected eNOS expression nor the protein level, but inhibited nearly all formation of NO in endothelium. GLP-1 (100 nM) and exendin-4 (1 and 10nM) decreased the amount of NO compared to control. Incubation of HCAEC with TNFα and incretin agonists did not change or moderately reduce the amount of NO compared to TNFα alone. CONCLUSIONS: TNFα and GA decrease production of NO in HCAEC, presumably by inducing reactive oxygen species or eNOS uncoupling. Incretin agonists in tested concentrations in the presence of l-arginine were not able to reverse this effect and instead led to a further reduction in NO production.
