Is mannitol the treatment of choice for patients with ciguatera fish poisoning?

CONTEXT: Ciguatera fish poisoning arises primarily from consumption of carnivorous reef fish caught in tropical and sub-tropical waters. Ciguatoxins, a class of tasteless, heat-stable, polycyclic toxins produced by dinoflagellates, accumulate through the food chain and concentrate in various carnivorous fish, such as groupers, barracudas, wrasses, amberjack, kingfishes, and eels. Characteristics of ciguatera fish poisoning include early nausea, vomiting, and diarrhea in the first one to two days post ingestion, followed by the appearance of sensory disturbances. The classic dysaesthesia is col…

Effects of short-term combined treatment with alendronate and elcatonin on bone mineral density and bone turnover in postmenopausal women with osteoporosis.

The antiresorptive drug elcatonin (ECT) is known to relieve pain in postmenopausal women with osteoporosis. A prospective open-labeled trial was conducted to compare the effects of short-term combined treatment with alendronate (ALN) and ECT on bone mineral density (BMD) and bone turnover with those of single treatment with ALN in postmenopausal women with osteoporosis. Two hundred and five postmenopausal osteoporotic women (mean age: 70 years) were recruited in our outpatient clinic. Forty-six women with back pain were treated with ALN and ECT (intramuscular, 20 units a week), and 159 women w

Множественный склероз: то, что мы узнали и можем узнать из электронной микроскопии.

Множественный склероз (MS) — воспалительное нейродегенеративное заболевание, характеризующееся возникновением демиелинированных повреждений в центральной нервной системе. Повреждения MS могут подвергаться воспоминанию, временно смягчая симптомы, но по мере развития болезни воспроизводство становится менее эффективным. Помимо повреждений, нормальные появляющиеся ткани мозга имеют тонкие изменения, потенциально указывающие на более широкую диффузную патологию и/или повышенную подверженность воздействию повреждений. Патология MS варьируется между повреждениями серых и белых веществ и их нормальны

Pineal expression-promoting element (PIPE), a cis-acting element, directs pineal-specific gene expression in zebrafish.

The pineal gland, sharing morphological and biochemical similarities with the retina, plays a unique and central role in the photoneuroendocrine system. The unique development of the pineal gland is directed by a specific combination of the expressed genes, but little is known about the regulatory mechanism underlying the pineal-specific gene expression. We isolated a 1.1-kbp fragment upstream of the zebrafish exo-rhodopsin (exorh) gene, which is expressed specifically in the pineal gland. Transgenic analysis using an enhanced green fluorescent protein reporter gene demonstrated that the proxi

An unusual presentation of metastatic prostate cancer in a 44-year-old man: A case report and review of the literature.

UNLABELLED: Prostate cancer is one of the two most common non-cutaneous cancers in men. Its presentation might be with unusual symptoms and cause the wrong initial diagnosis. This case report discusses a rare neurologic manifestation of advanced metastatic cancer in a low-risk man. He had been receiving treatment for multiple sclerosis incorrectly due to unusual manifestations such as claudication and pelvic, leg, and shoulder pain. The patient underwent a whole-body bone scan and then a transrectal ultrasound-guided biopsy, which confirmed metastatic prostate cancer with a Gleason score betwe

Molecular-Based Treatment Strategies for Osteoporosis: A Literature Review.

Osteoporosis is an unavoidable public health problem in an aging or aged society. Anti-resorptive agents (calcitonin, estrogen, and selective estrogen-receptor modulators, bisphosphonates, anti-receptor activator of nuclear factor κB ligand antibody along with calcium and vitamin D supplementations) and anabolic agents (parathyroid hormone and related peptide analogs, sclerostin inhibitors) have major roles in current treatment regimens and are used alone or in combination based on the pathological condition. Recent advancements in the molecular understanding of bone metabolism and in bioengin

Транскриптомное профилирование после разрушения клеток В свидетельствует о том, что в множестве склерозов происходят изменения в центральных и периферийных иммунных клетках.

Множественный склероз (MS) представляет собой сложное, генетически смешанное аутоиммунное заболевание CNS, в котором истощение клеток с антиCD20 средоточием B является весьма эффективным средством лечения ранних заболеваний. Хотя в предыдущих исследованиях изучалось воздействие истощения клеток B на отдельные поднаборы иммунных клеток с использованием методов, основанных на потоках цитометрии, терапевтическое воздействие на иммунный ландшафт пациента неизвестно. В этом исследовании мы изучали вопрос о том, как методы лечения, разрушающие клетки B, модифицируют иммунный ландшафт с использование

Initial non-weight-bearing therapy is important for preventing vertebral body collapse in elderly patients with clinical vertebral fractures.

PURPOSE: The aim of the present conventional observational study was to compare the clinical outcomes of initial non-weight-bearing therapy and conventional relative rest therapy among elderly patients with clinical vertebral fractures. METHODS: In total, 196 consecutive patients with clinical vertebral fractures (mean age: 78 years) who were hospitalized for treatment between January 1999 and March 2007 were analyzed. Initial non-weight-bearing therapy consisted of complete bed rest allowing rolling on the bed without any weight-bearing to the spine for 2 weeks, followed by rehabilitation we

Dectin-1 signaling inhibits osteoclastogenesis via IL-33-induced inhibition of NFATc1.

Abnormal osteoclast activation contributes to osteolytic bone diseases (OBDs). It was reported that curdlan, an agonist of dectin-1, inhibits osteoclastogenesis. However, the underlying mechanisms are not fully elucidated. In this study, we found that curdlan potently inhibited RANKL-induced osteoclast differentiation and the resultant bone resorption. Curdlan inhibited the expression of nuclear factor of activated T-cells, cytoplasmic 1 (NFATc1), the key transcriptional factor for osteoclastogenesis. Notably, dectin-1 activation increased the expression of MafB, an inhibitor of NFATc1, and IL

Молекуляризация допанта в β-Ga2O3: образование N2 в условиях неравновесия.

Микроскопическая судьба допингов, вводимых в условиях неравновесия, остается в значительной степени нерешенной в отношении оксидов широкополосного раствора. С помощью спектроскопии рентгеновского поглощения N-конечного N-K, мы непосредственно решим местную конфигурацию связывания имплантированного азота ()100β-Ga2O3. В спектрре доминирует резкий резонанс, присущий NN, который систематически усиливается при аннезе, что дает прямой спектроскопический отпечаток молекулярного образования азота. Первые принципы расчетов и многоразового моделирования воспроизводят эти спектральные особенности и опре

LAMP5 modulates IRF4 stability and nuclear transport: a critical mechanism in myeloma progression and therapy.

Multiple myeloma is a malignant hematopoietic neoplasm characterized by unclear molecular mechanisms and lack of highly effective targeted therapies for clinical application. Interferon regulatory factor 4 (IRF4) is a well-known core transcription factor that regulates the progression of myeloma, but the molecular mechanisms underlying its protein homeostasis regulation are unknown. Our research shows that lysosomal-associated membrane protein 5 (LAMP5) interacts with IRF4 and prevents its degradation through the autophagy-lysosome pathway, thereby facilitating the progression of myeloma. Addi

The Whole-Body MRI Reporting and Data System Guidelines for Prostate Cancer (MET-RADS-P), Multiple Myeloma (MY-RADS), and Cancer Screening (ONCO-RADS).

Whole-body magnetic resonance imaging (WB-MRI) is being employed with increasing frequency to evaluate a broader spectrum of patients with diverse types of cancer and for cancer screening purposes. While clinical guidelines support its use, a standardized radiological approach is still lacking. To improve consistency in the acquisition, interpretation, and reporting of WB-MRI examinations, three reporting and data systems (RADSs) have been recently suggested: METastasis Reporting and Data System for Prostate Cancer (MET-RADS-P), Myeloma Response Assessment and Diagnosis System (MY-RADS), and O

Diagnosis and Treatment of Bone Metastases in Breast Cancer: Radiotherapy, Local Approach and Systemic Therapy in a Guide for Clinicians.

The standard care for metastatic breast cancer (MBC) is systemic therapies with imbrication of focal treatment for symptoms. Recently, thanks to implementation of radiological and metabolic exams and development of new target therapies, oligometastatic and oligoprogressive settings are even more common-paving the way to a paradigm change of focal treatments role. In fact, according to immunophenotype, radiotherapy can be considered with radical intent in these settings of patients. The aim of this literature review is to analyze available clinical data on prognosis of bone metastases from brea

Cancer disparities: an extensive review.

Cancer disparities are persistently a significant public health burden worldwide and disproportionately impact the underserved populations. To effectively combat cancer disparities, a clear understanding of their causes and patterns is essential. Currently, government data and peer-reviewed research journals display a wide range of data to describe the extent of different cancer disparities. However, there are still gaps in understanding the scope and patterns of these disparities and in adopting practical approaches to eliminate them adequately. Accordingly, we examine essential topics that a
