BACKGROUND: Tardive dyskinesia (TD) remains a troublesome adverse effect of conventional antipsychotic (neuroleptic) medication. It has been proposed that TD could have a component of central cholinergic deficiency. Cholinergic drugs have been used to treat TD. OBJECTIVES: To determine the effects of cholinergic drugs (arecoline, choline, deanol, lecithin, meclofenoxate, physostigmine, RS 86, tacrine, metoxytacrine, galantamine, ipidacrine, donepezil, rivastigmine, eptastigmine, metrifonate, xanomeline, cevimeline) for treating antipsychotic-induced TD in people with schizophrenia or other chronic mental illness...

Right coronary artery (RCA) originating from the left coronary system is a subtype of single coronary artery (SCA) anomaly, and the origin of RCA as a branch from the left anterior descending artery (LAD) is a very rare variant. A 55-year-old male who had a percutaneous coronary intervention (PCI) history was hospitalized due to acute coronary syndrome. Coronary angiography revealed an aberrant RCA originating from the mid-LAD as well as stent thrombosis. A successful PCI was performed and he was discharged from the hospital three days after the PCI...

Introduction: Dysphagia is a risk factor for aspiration pneumonia and acute respiratory failure in acute stroke patients. Dysphagia lusoria is caused by compression on the esophagus from artery lusoria, when the aberrant right subclavian artery arises from the descending aortic arch. We present a rare case report of pre-stroke undiagnosed dysphagia lusoria as a cause of aspiration pneumonia with acute respiratory failure in a 67-year-old female patient admitted with a minor left intracerebral hemorrhage in the left basal ganglia...

We present the rare case of a fatal anaphylactic reaction to gadobutrol, a magnetic resonance imaging contrast agent, in a 42-year-old man. The patient underwent elective magnetic resonance imaging for diagnostic clarification of a suspicious finding in the abdomen. The patient had undergone contrast-enhanced computed tomography previously without the occurrence of any adverse effects. Adverse drug reactions in gadobutrol have a very low prevalence of 0.32%-3.5%, with serious adverse drug reactions in <0...

During aging, human response times (RTs) to unisensory and crossmodal stimuli decrease. However, the elderly benefit more from crossmodal stimulus representations than younger people. The underlying short-latency multisensory integration process is mediated by direct crossmodal connections at the level of primary sensory cortices. We investigate the age-related changes of these connections using a rodent model (Mongolian gerbil), retrograde tracer injections into the primary auditory (A1), somatosensory (S1), and visual cortex (V1), and immunohistochemistry for markers of apoptosis (Caspase-3), axonal plasticity (Growth associated protein 43, GAP 43), and a calcium-binding protein (Parvalbumin, PV)...

Primary amebic meningoencephalitis (PAM) is a rapidly fatal infection caused by the free-living ameba Naegleria fowleri. PAM occurs principally in healthy children of less than 13 years old with a history of recent exposure to warm fresh water. While as yet not a reportable disease, the Centers for Disease Control and Prevention (CDC) documents a total of 143 cases in the United States. Only four patients have survived. Infection results from water containing N. fowleri entering the nose, followed by migration of the amebae to the brain...

Oligoasthenoteratozoospermia (OAT) is characterized as low sperm count, decreased sperm motility and structural abnormalities of the sperm head in the same patient. However, very few studies reported the genetic alterations associated with OAT. Here we report a 38-year-old patient with OAT from a consanguineous family, with 2-6 million/mL sperm density, 2.1-3.8% normal sperm morphology and immotile sperm. Whole-exome sequencing (WES) identified homozygous variant c.1259A>G:p.Y420C in the TDRD6 gene. TDRD6 is a testis-specific expressed protein that was localized to the chromatoid bodies in germ cells and played an important role in the nonsense-mediated decay pathway...

Intercellular communication through gap junction channels plays a key role in cellular homeostasis and in synchronizing physiological functions, a feature that is modified in number of pathological situations. In the brain, astrocytes are the cell population that expresses the highest amount of gap junction proteins, named connexins. Several techniques have been used to assess the level of gap junctional communication in astrocytes, but so far they remain very difficult to apply in adult brain tissue. Here, using specific loading of astrocytes with sulforhodamine 101, we adapted the gap-FRAP (Fluorescence Recovery After Photobleaching) to acute hippocampal slices from 9 month-old adult mice...

We report here a 74-year-old male who was seen for recurrent respiratory infections, fatigue, and weight loss in November 2016. Bone marrow biopsy showed 90% involvement by plasma cell myeloma (PCM) [90% plasma cells, 40% cellular bone marrow]. Cytogenetic analysis of the bone marrow showed a complex karyotype described as: 53,Y,add(X)(p22.1),del(1)(p13p22),+3,add(3)(p13),add(4)(p12),+6,del(6)(q13q25),t(8;22)(q24.1;q11.2),+9,+11,+15,+15,+21[7]/46,XY[13].

Lipomas of the digestive tract are rare benign tumours which, in most cases, are totally asymptomatic. Because of their localization within the intestinal wall, endoscopy may be completely negative so contrast-enhanced computed tomography (CT) is very important for detecting and typing these lesions. The case of a 49-year-old man with abdominal pain is presented. Colonoscopy and biopsy of a polypoid lesion on the right colonic flexure concluded for tubulovillous adenoma. The subsequent CT showed a polylobate lesion of 5 cm in diameter with predominant fat density causing luminal sub-stenosis...

INTRODUCTION: Neonatal care advances have resulted in improved survival but have raised concerns of increase in neurodevelopmental impairment. This study looked at long-term neurodevelopmental outcomes at ages 5 and 8 years of very low birthweight infants born in the 2000s as compared to the 1990s. Neurodevelopmental assessment at 2 years old was compared to that at 5 and 8 years to determine if assessment at 2 years was predictive of later outcomes. MATERIALS AND METHODS: A retrospective cohort study of consecutive infants with birthweight less than 1250 grams admitted to a tertiary centre in Singapore between January 1994 to December 1995 (Epoch I) and January 2004 to December 2005 (Epoch II) were included...

In this study, a top cover system is investigated as a control for emissions during the aftercare of new landfills and for old landfills where biogas energy production might not be profitable. Different materials were studied as landfill cover system in lab-scale columns: mechanical-biological pretreated municipal solid waste (MBP); mechanical-biological pretreated biowaste (PB); fine (PBSf ) and coarse (PBSc ) mechanical-biological pretreated mixtures of biowaste and sewage sludge, and natural soil (NS). The effectiveness of these materials in removing methane and sulphur compounds from a gas stream was tested, even coupled with activated carbon membranes...

BACKGROUND: Birt-Hogg-Dubé syndrome is a genetic syndrome caused by mutations in the FLCN gene. The main symptoms are lung bullae and pneumothorax, benign and malignant kidney tumors, and facial fibrofolliculoma. The risk of pneumothorax is considerable between ages 20-40 years, but decreases markedly after this age range and first-time pneumothorax after age 50 years is rare. Fibrofolliculomas usually occur between ages 35 and 45 years, while the risk for kidney cancer increases steadily with age, starting in young adulthood...

BACKGROUND: Gastrointestinal stromal tumors (GIST) are the most common mesenchymal tumors of the gastrointestinal tract and liver and peritoneum are the main sites of recurrence. Ovarian metastases from GIST are very rare. CASE PRESENTATION: A 50 years-old woman was found to have a pelvic mass on transvaginal ultrasound (TV-US) and computed tomography (CT)-scan, considered as a right ovarian mass. The patient underwent surgical abdominal exploration that showed an ileal mass, a normal right ovary and an irregular and vascularized surface of the left ovary...

In the United States, the rate of primary and secondary syphilis has increased by 18% in 2016, the highest rate since 1993. These patients can often present to the emergency department (ED) in various stages. Although syphilis is well described in the literature, there is a paucity of ED reports of atypical cases. A 22-yr-old male presented to the ED complaining of neck pain. The patient was found to have right-sided tender cervical lymphadenopathy causing neck pain. A thorough physical exam revealed diffuse lymphadenopathy...

A case of an extremely healthy, active, 96-year-old patient, nonsmoker, is reviewed. He was initially treated for left V1, V2, and V3 trigeminal neuralgia in 2001, at age 80, with stereotactic radiosurgery (SRS) with a dose of 80 Gy to the left retrogasserian trigeminal nerve. He remained asymptomatic for nine years until his trigeminal pain recurred in 2010. He was first treated medically but was intolerant to increasing doses of carbamazepine and gabapentin. He underwent a second SRS in 2012 with a dose of 65...

Tuberculosis combined with brucellosis is a very rare condition. Overlapping clinical presentation and laboratory parameters of tuberculosis and brucellosis may lead to misdiagnosis or delayed diagnosis of the condition. The current study presents the case of a 45-year-old male with symptoms of lower back pain, non-tender swelling in the right flank, intermittent hyperpyrexia, sweating, body aches and numbness and weakness of right lower limb. A lumbar computed tomograph (CT) scan and magnetic resonance imaging indicated vertebral destruction and the formation of sequestra and thecal sac compression...

Trypanosoma rangeli and Trypanosoma cruzi are generalist trypanosomes sharing a wide range of mammalian hosts; they are transmitted by triatomine bugs, and are the only trypanosomes infecting humans in the Neotropics. Their origins, phylogenetic relationships, and emergence as human parasites have long been subjects of interest. In the present study, taxon-rich analyses (20 trypanosome species from bats and terrestrial mammals) using ssrRNA, glycosomal glyceraldehyde-3-phosphate dehydrogenase (gGAPDH), heat shock protein-70 (HSP70) and Spliced Leader (SL) RNA sequences, and multilocus phylogenetic analyses using 11 single copy genes from 15 selected trypanosomes, provide increased resolution of relationships between species and clades, strongly supporting two main sister lineages: lineage Schizotrypanum, comprising T...
