BACKGROUND: Early and late dumping are complications of gastric bypass surgery. Early dumping occurs within an hour after eating, when the emptying of food into the small intestine triggers rapid fluid shifts into the intestinal lumen and the release of gastrointestinal hormones, resulting in gastrointestinal and vasomotor symptoms. Late dumping occurs between 1 and 3 hours after carbohydrate ingestion and is caused by an exaggerated insulin release, resulting in hypoglycemia. Almost no data are currently available on the prevalence of early and late dumping or their impact on health-related quality of life (QoL)...

Millions of people are regularly exposed to ozone, a gas known to contribute significantly to worsening the symptoms of patients with asthma. However, the mechanisms underlying these ozone exacerbation effects are not fully understood. In this study, we examined the exacerbation effect of ozone in OVA-induced asthma mice and tried to demonstrate the protective mechanism of vitamin E (VE). An asthma mouse model was established, and used to identify the exacerbating effects of ozone by assessing cytokine and serum immunoglobulin concentrations, airway leukocyte infiltration, histopathological changes in lung tissues, and airway hyper-responsiveness...

Thyroid storm is a potentially lethal complication of hyperthyroidism with increased thyroid hormones and exaggerated symptoms of thyrotoxicosis. First-line therapy includes methimazole (MMI) or propylthiouracil (PTU) to block production of thyroid hormones as a bridge toward definitive surgical treatment. Untreated thyroid storm has a mortality rate of up to 30%; this is particularly alarming when patients cannot tolerate or fail pharmacotherapy, especially if they cannot undergo thyroidectomy. Therapeutic plasma exchange (TPE) is an ASFA category III indication for thyroid storm, meaning the optimum role of this therapy is not established, and there are a limited number of cases in the literature...

Sensory hypersensitivity is a common symptom in autism spectrum disorders (ASDs), including Fragile X Syndrome (FXS), and frequently leads to tactile defensiveness. In mouse models of ASDs, there is mounting evidence of neuronal and circuit hyperexcitability in several brain regions, which could contribute to sensory hypersensitivity. However, it is not yet known whether or how sensory stimulation might trigger abnormal sensory processing at the circuit level or abnormal behavioral responses in ASD mouse models, especially during an early developmental time when experience-dependent plasticity shapes such circuits...

Huperzine A has been used for improving symptoms of Alzheimer's disease. Its cholinergic side effect is thought to be an exaggerated pharmacological outcome linked to its high brain or CNS concentrations. Although Huperzine A is brain penetrable, its interaction with efflux transporters (ABCB1 and ABCG2) has not been fully investigated. The aim of the present study was to characterize roles of ABCB1 and ABCG2 in the transmembrane transport of Huperzine A and identify a rate limiting step in its brain distribution...

Post-traumatic stress disorder is characterized by exaggerated threat response, and theoretical accounts to date have focused on impaired threat processing and dysregulated prefrontal-cortex-amygdala circuitry. Nevertheless, evidence is accruing for broad, threat-neutral sensory hyperactivity in post-traumatic stress disorder. As low-level, sensory processing impacts higher-order operations, such sensory anomalies can contribute to widespread dysfunctions, presenting an additional aetiological mechanism for post-traumatic stress disorder...

BACKGROUND: Adult T-cell Leukemia/Lymphoma (ATLL) is classified as a peripheral CD4+ T-cell neoplasm caused by the human T-cell lymphotropic virus type 1 (HTLV-1). Typical symptoms are associated with leukemic infiltration; however, atypical and exaggerated manifestations of verrucous carcinoma have also been described. CASE REPORT: We present here the case of a patient with multiple skin lesions, ischemic necrosis in the hallux and lymphadenopathies. Biopsies were taken, which showed verrucous epidermal carcinoma and cutaneous lymphoma...

Historically, the symptoms of posttraumatic stress disorder (PTSD) have garnered attention and controversy due to symptom overlap with other disorders. To improve diagnostic specificity, researchers have proposed to reformulate PTSD symptoms into a parsimonious set of core criteria. The core symptoms consisted of recurrent distressing dreams or flashbacks; internal or external avoidance; and hypervigilance or exaggerated startle. The purpose of this study was to examine a previously proposed set of "core" PTSD criteria in identifying cases of PTSD within a veteran sample...

High conflict and low warmth in families may contribute to immune cells developing a tendency to respond to threats with exaggerated inflammation that is insensitive to inhibitory signaling. We tested associations between family environments and expression of genes bearing response elements for transcription factors that regulate inflammation: nuclear factor kappa B (NF-κB) and glucocorticoid receptor. The overall sample (47 families) completed interviews, questionnaires, and 8-week daily diary assessments of conflict and warmth, which were used to create composite family conflict and warmth scores...

Symptoms of schizophrenia have been linked to insults during neurodevelopment such as NMDA receptor antagonist exposure. In animal models, this leads to schizophrenia-like behavioral symptoms as well as molecular and functional changes within hippocampal and prefrontal regions. The aim of this study was to determine how administration with the NMDA receptor antagonist, phencyclidine (PCP), during neurodevelopment affects functional network changes within the hippocampus and medial prefrontal cortex (mPFC). We recorded field potentials in vivo following electrical brainstem stimulation and observed a suppression of evoked theta power in ventral hippocampus, while evoked gamma power in mPFC was enhanced in rats administered neonatally with PCP...

The pathophysiology of hidradenitis suppurativa (HS) is not well understood. Some of our knowledge comes from clinical and epidemiological observations, along with studies of the histopathology and immunohistochemistry of affected skin. More recently, cutaneous molecular studies and transcriptomic analyses have provided additional information regarding inflammatory processes. The chronic cutaneous inflammation, systemic symptoms, and associated comorbidities suggest that HS should be classified as an immune-mediated disease, rather than a primary infectious disease...

Prescription opioids are a mainstay in the treatment of acute moderate to severe pain. However, chronic use leads to a host of adverse consequences including tolerance and opioid-induced hyperalgesia (OIH), leading to more complex treatment regimens and diminished patient compliance. Patients experiencing OIH paradoxically experience exaggerated nociceptive responses instead of pain reduction after chronic opioid usage. The development of OIH and tolerance tend to occur simultaneously and, thus, present a challenge when studying the molecular mechanisms driving each phenomenon...

BACKGROUND: Contrary to DSM-5 definition based on recurrence of low grade hypomanic and depressive symptoms, cyclothymia is better defined in a neurodevelopmental perspective as an exaggeration of cyclothymic temperament. Emotional dysregulation with extreme mood instability and reactivity is the core features of the complex symptomatology. METHOD: In the present article, we critically reviewed the literature on the diagnosis and treatment of cyclothymia, focusing on the temperamental and neurodevelopmental perspectives...

BACKGROUND: Based on anecdotal and observational evidence, we hypothesized that the prevalence of cervical musculoskeletal disorder (C-MSD) would be high among plastic surgeons. A questionnaire review was undertaken to test this hypothesis. Ergonomic assessment was undertaken to assess causal factors of C-MSD. METHOD: An anonymous questionnaire recording demographics, physical symptoms and behavioral responses to C-MSD was distributed to UK Plastic Surgery consultants...

BACKGROUND: Early cognitive models of mania posit that a cognitive triad consisting of unrealistically optimistic beliefs about the self, world and future may predispose vulnerable individuals to develop manic symptoms. Hypomanic personality traits (HYP) pose such a vulnerability factor in the etiopathogenesis of mania. METHODS: To test the cognitive tenet of overly optimistic views of the future, 24 individuals with high-HYP and 24 age- and sex-matched controls (low-HYP) performed a belief update paradigm, during which they estimated their personal chances to experience future positive and negative life events...

The failure of postoperative surgical site infection to resolve after appropriate antibiotic therapy should alert the clinician to other diagnoses. Pyoderma gangrenosum (PG) is an inflammatory neutrophilic dermatosis that is typically characterized by necrotizing ulceration. PG can be exacerbated by minor trauma leading to exaggerated skin injury, a condition known as pathergy. We present a case series of PG arising after immediate reconstruction for breast oncological surgery from 1st January 2006 to 1st September 2014...

Patients with factitious disorders intentionally fabricate, exaggerate or feign physical and/or psychiatric symptoms for various open and covert psychological reasons. There are many issues regarding the diagnostic state and classification of factitious disorders. Both the categorical differentiation of and clinical continuum ranging from somatoform/dissociative disorders to malingering are being controversially debated. Epidemiological studies on the frequency of factitious disorder meet basic methodological difficulties...

Background: Left ventricular hypertrophy (LVH) is associated with intra-ventricular dyssynchrony at systolic phase during exercise in hypertensive patients. However, dypsnea on exertion is much more correlated with diastolic phase. We investigated whether LVH is associated with diastolic dyssynchrony during exercise in patients with hypertension. Methods: Ninety hypertensive patients with exertional dyspnea and 30 control individuals were enrolled. Exercise stress echocardiography was performed using a symptom limited, multistage supine bicycle test...

Influenza A virus (IAV) infections lead to severe inflammation in the airways. Patients with chronic obstructive pulmonary disease (COPD) characteristically have exaggerated airway inflammation and are more susceptible to infections with severe symptoms and increased mortality. The mechanisms that control inflammation during IAV infection and the mechanisms of immune dysregulation in COPD are unclear. We found that IAV infections lead to increased inflammatory and antiviral responses in primary bronchial epithelial cells (pBECs) from healthy nonsmoking and smoking subjects...
