Ten-Fold Elevation of Chromogranin A Level Unrelated to a Neuroendocrine Tumor: A Case Report of the Diagnostic Interference of Proton Pump Inhibitors.

Chromogranin A (CgA) is a well-known biomarker for neuroendocrine tumors (NETs). However, due to its non-specificity, a proper assessment of CgA test results requires a detailed knowledge of the factors, conditions, and medications influencing its serum concentration. We describe a case of a 61-year-old patient presenting with a mass suspicious of a gastrointestinal NET and an exceedingly high level of serum CgA persistent after mass resection.

Amphotericin B Nano-Assemblies Circumvent Intrinsic Toxicity and Ensure Superior Protection in Experimental Visceral Leishmaniasis with Feeble Toxic Manifestation.

In spite of its high effectiveness in the treatment of both leishmaniasis as well as a range of fungal infections, the free form of the polyene antibiotic amphotericin B (AmB) does not entertain the status of the most preferred drug of choice in clinical settings. The high intrinsic toxicity of the principal drug could be considered the main impedance in the frequent medicinal use of this otherwise very effective antimicrobial agent. Taking into consideration this fact, the pharma industry has introduced many novel dosage forms of AmB to alleviate its toxicity issues.

Motor Cortex Response to Pleasant Odor Perception and Imagery: The Differential Role of Personality Dimensions and Imagery Ability.

Background: Neuroimaging studies have shown a complex pattern of brain activation during perception of a pleasant odor and during its olfactory imagery. To date, little is known regarding changes in motor cortex excitability during these tasks. Bergamot essential oil (BEO) is extensively used in perfumes and cosmetics for its pleasantness.

Acute social and somatic stress alters cortical metaplasticity probed with non-invasive brain stimulation in humans.

Studying the neuronal mechanisms that govern the cortical adaptations to acute stress is critical for understanding the development of neuropsychiatric diseases. Homeostatic plasticity stabilizes the neural activity in which a previous synaptic event drives subsequent synaptic plasticity. In this study, we evaluated the effect of acute stress induced with the socially evaluated cold pressor test (SECPT) on cortical metaplasticity in humans using a non-invasive brain stimulation protocol.

The Opioid Crisis: How to Lessen the Burden on Emergency Departments by At-risk Populations.

Background The opioid crisis in the United States of America has been worsening due to previous sharp increases in opioid prescriptions and a lack of resources available to those affected. Emergency departments (ED) across the nation have been exhausted with a constant influx of patients related to opioid-related issues. Because of limited resources, it is crucial to efficiently distribute rehabilitation and mental wellness efforts amongst those most susceptible to opioid abuse.

Treating Bell's Palsy With Osteopathic Manipulative Medicine: A Case Report.

Bell's palsy (BP) occurs when the facial nerve (CN VII) is swollen, inflamed, or compressed, resulting in facial weakness or paralysis; etiology is unknown. BP patients often succumb to a decreased quality of life due to the inability to make facial expressions, increased sensitivity to auditory stimuli, and dysregulation in tear and saliva production. Despite conventional examination and therapy options, the syndrome is majorly regarded as idiopathic and left unresolved for many patients.

Effects of taurine acute intake on cortical excitability and post-exercise facilitation: A TMS study.

Taurine (TAU) is one of the most abundant amino acids in the brain. It has many important physiological functions. The effects of TAU supplementation on brain function need to be further characterized in humans.

Clival Defect with Primary CSF Rhinorrhea: A Very Rare Presentation with Challenging Management.

Background: Primary spontaneous cerebrospinal fluid (CSF) rhinorrhea due to clival defect is an extremely rare presentation, and only 6 cases have been reported in the literature so far.

Case Description: We present a unique case of a 64-year-old woman who presented with a 2-year history of ongoing CSF rhinorrhea. She had similar episode at the age of 40 years and suffered from meningitis.

Circulating Cell-Free DNA to Determine the Fetal RHD Status in All Three Trimesters of Pregnancy.

Objective: To estimate the accuracy of a new assay to determine the fetal RHD status using circulating cell-free DNA.

Methods: This was a prospective, observational study. Maternal blood samples were collected in each trimester of pregnancy in 520 nonalloimmunized RhD-negative patients.

Neurotropic cutaneous malignant melanoma with contiguous spread to spinal cord, an extremely rare presentation.

Neurotropic melanoma (NM) is a rare variant of cutaneous melanomas. Compared with conventional melanoma, NM is more locally aggressive with an increased tendency for local recurrence but less likely for nodal or distant metastases. The often amelanotic, benign appearance may lead to treatment issues such as late presentation, diagnostic delay, misdiagnosis, insufficient surgical margins, and recurrence with resulting poor outcome.

Malignant paraganglioma, a rare presentation with foot drop: a case report.

Paragangliomas (or extra-adrenal paragangliomas) are rare neuroendocrine tumors that arise from the extra-adrenal autonomic paraganglia, small organs consisting mainly of neuroendocrine cells that are derived from the embryonic neural crest and have the ability to secrete catecholamines. This is in contrast to pheochromocytomas, where tumors occur in the adrenal gland. Malignant paraganglioma is a very rare presentation.

17-hydroxyprogesterone caproate for preterm rupture of the membranes: a multicenter, randomized, double-blind, placebo-controlled trial.

Objective: Preterm rupture of membranes (PROM) is associated with an increased risk of preterm birth and neonatal morbidity. Prophylactic 17-hydroxyprogesterone caproate (17OHP-C) reduces the risk of preterm birth in some women who are at risk for preterm birth. We sought to test whether 17OHP-C would prolong pregnancy or improve perinatal outcome when given to mothers with preterm rupture of the membranes.

Vertical and horizontal transmission of Candida albicans in very low birth weight infants using DNA fingerprinting techniques.

Background: Very low birth weight infants (VLBW, < or = 1500 g) are at increased risk for invasive disease caused by fungi, and colonization is an important risk factor. This study was designed to examine the effect of maternal flora on Candida colonization of VLBW infants.

Methods: Body site samples were collected within 24 hours of delivery from mothers who gave birth to VLBW infants, from their infants at birth, and then weekly for 12 weeks or until death or discharge.
