Microplastics are frequently detected in freshwater environments, serving as a new factitious substrate for colonization of biofilm-forming microorganisms. Distinct microbial assemblages between microplastics and surrounding waters have been well documented; however, there is insufficient knowledge regarding biofilm colonization of plastic and non-plastic substrates, despite the fact that microbial communities generally aggregate on natural solid surfaces. In this study, the effects of substrate type on microbial communities were evaluated by incubation of biofilms on microplastic substrates (polyethylene and polypropylene) and natural substrates (cobblestone and wood) for 21 days under controlled conditions...

BACKGROUND: Chronic prurigo (CPG) is a distinct disease characterized by chronic pruritus, history and/or signs of prolonged scratching and multiple pruriginous lesions. It may present with various clinical manifestations, including papules, nodules, plaques or umbilicated lesions. Some patients with chronic pruritus show pruriginous linear and scaring scratch lesions (LSSL) and it is unclear whether these lesions belong to the spectrum of CPG. OBJECTIVE: To achieve a consensus on the classification of pruriginous LSSL and establish criteria to differentiate them from similar appearing conditions of different nature...

Tissue plasminogen activator (tPA) is administered to patients with suspected ischemic stroke to improve blood flow to the brain In rare cases, patients present with complaints of stroke symptoms that appear to be non-organic due to malingering, factitious disorder, or conversion disorder (psychogenic stroke mimics). Deciding whether or not to administer tPA to these patients can be challenging. The risk of hemorrhage after administration of tPA is low, but not zero. The ethical principles of beneficence and nonmaleficence need to be weighed carefully in these situations...

Practitioners and researchers have long been challenged with identifying deceptive response styles in forensic contexts, particularly when differentiating malingering from factitious presentations. The origins and the development of factitious disorders as a diagnostic classification are discussed, as well as the many challenges and limitations present with the current diagnostic conceptualization. As an alternative to a formal diagnosis, forensic practitioners may choose to consider most factitious psychological presentations (FPPs) as a dimensional construct that are classified like malingering as a V code...

: A 12-year-old boy, with intermittent abdominal pain from 3 years of age, presented with increased frequency of right lower quadrant pain (at least three episodes per week over the past six months) and pain during micturition affecting school attendance. His family history included referred urolithiasis. An abdominal ultrasound performed 1 year before our visit showed a small stone of 4 mm in the right renal pelvis for which he did not receive any therapy. The patient brought 25 hard stones with irregular outline, 2-8 mm in diameter, of deep brown/grey colour that he claimed to have found in his underwear (figure 1)...

Our team of diabetologist is challenged by the case of a 41 year-old woman with recurrent hypoglycaemic episodes. Her clinical background was complex with, among others, a neuroendocrine tumor, a nonalcoholic steatohepatitis and an adrenal insufficiency; these conditions require the exploration of several potential causes. After excluding an endogenous etiology, a factitious hypoglycemia was quicky suspected by clinicians. However, several venous samples showed normal insulinemia and a moderately decreased C-peptide...

Factitial cheilitis is a rare diagnosis of exclusion that occurs most frequently in young women with a history of anxiety disorders and recent psychosocial stressors. It presents as continuous keratinaceous build-up, crusting, and desquamation of the lips, consistent with exfoliative cheilitis. Affected areas can progress to superinfection with Staphylococcus aureus or Candida albicans. We report a case of a 23-year-old woman who presented with diffuse hyperkeratosis of the upper and lower lips that was initially suspected to be allergic or irritant contact dermatitis based on clinical examination...

BACKGROUND: Mid-face Toddler Excoriation Syndrome (MiTES) is a condition recently reported in 3 unrelated children.1 Habitual scratching from the first year of life inflicted deep, chronic, scarring wounds around the nose and eyes. One had mild neurological deficit but there was no other evidence of insensitivity to pain. Bilateral distribution and localisation to the mid-face distinguish MiTES from other causes of self-inflicted skin damage such as trigeminal trophic syndrome. An earlier study of five siblings from a consanguineous Irish family, with lesions corresponding to MiTES plus other sensory deficits, showed homozygous mutations in a gene for hereditary sensory and autonomic neuropathy (HSAN8), PRDM122 ...

Mechanisms of anaesthetic actions on memory have largely focused on easily definable aspects of episodic memory, with emphasis on particular drug interactions on specific memory processes. However, the memory landscape of the perioperative experience includes many facets that lie outside these conceptualisations. These include patient recall of preoperative conversations, patient beliefs regarding allergies and unusual/uncommon anaesthetic events, memories of awareness, and particularly vivid dreams during anaesthesia...

PURPOSE: We sought to describe patterns of factitious urinary stone submission over time by investigating a contemporary stone analysis database and comparing two distinct time points. MATERIALS AND METHODS: We retrospectively reviewed a single stone analysis lab database at two time points, 1990 and 2010, and compared total incidence of factitious stone submission, as well as gender patterns and type of factitious stone submitted. RESULTS: A total of 27,014 stones were analyzed, 16,216 (60%) from 1990 and 10,798 (40%) from 2010 with a decrease in total incidence from 2...

Introduction: Factitious hypoglycemia, caused by the surreptitious use of insulin and sulfonylureas, is one of the most challenging differential diagnoses of hypoglycemia. Diagnosis is usually established via exclusion with respect to the special patterns of plasma insulin and C-peptide during hypoglycemic episodes. Case Presentation: We report a case of recurrent hypoglycemic episodes and confusing patterns of insulin and C-peptide levels. In the primary evaluations, insulinoma was suspected considering the high plasma concentrations of insulin and C-peptide, besides negative urine and plasma sulfonylureas during hypoglycemic episodes...

Factitious Disorder Imposed on Another (FDIA), also known as Munchausen Syndrome by Proxy (MSbP) is a very serious form of child abuse. The perpetrator, usually the mother, invents symptoms or causes real ones in order to make her child appear sick. Usually this is due to a maladaptive disorder or to an excessive of attention-seeking on her part. We report here two new cases of FDIA. The first one is a 9-year-old boy with a history of convulsive episodes, reduced verbal production, mild psychomotor disorder and urological problems who underwent several invasive procedures and hospitalizations before a diagnosis of FDIA was made...

BACKGROUND: Dermatitis artefacta is a relevant and frequently unrecognized clinical condition associated with self-harming behavior, in which unconscious manipulation causes skin lesions. While atypical lesions and an unusual disease course may give rise to clinical suspicion of a self-induced disorder, questioning and examining these patients usually fails to confirm or clarify this suspicion. In this setting, the dermatopathologist may be faced with the question whether there are any histological signs corroborating the diagnosis of dermatitis artefacta...

Dermatitis artefacta (DA) or artefactual skin disease (ASD) is a factitious skin disorder rarely reported in the pediatric population. Skin lesions are produced deliberately either consciously or in a dissociative state to satisfy an underlying psychological need. Children may present with acutely formed skin changes or with chronic lesions, quite often having seen other specialists during their journey. The mechanism of formation of skin lesions can vary from the application of pigment onto the skin to simulate disease or more destructive techniques like the injection of irritant substances into the skin...

BACKGROUND: Malingering is when a patient feigns illness for secondary gain. While most patients with malingering manufacture or exaggerate symptoms, some patients may induce illness. Previous reports of malingering patients inducing illness include sepsis, kidney pain, migraine, and chest pain. However, acute poisoning as a manifestation of malingering appears to be rare. CASE REPORT: We describe the case of a 39-year-old man who presented to the emergency department complaining of diffuse body pain...

BACKGROUND: Stigma refers to the wounds reproduced on the human body, similar to the ones inflicted on the Christ during his crucifixion, on the palms, soles, and head, as well as the right or the left side of the chest, the lips and, the back. Whether they are genuine or fabricated, stigmata are still considered a medical enigma. OBJECTIVE: To summarize and analyze all available medical data about stigmata, integrating both its dermatological and psychiatric features...

BACKGROUND: In most of the cases regarding children, factitious disorders (FDs) are intentionally produced by parents. Less attention is paid to FDs in which a child or adolescent intentionally induces or falsifies the disease to attain a patient's role. CASE PRESENTATION: A 13-year-old immigrated and adopted boy previously underwent an operation for renal joint syndrome and was affected by recurrent episodes of renal colic. The boy was admitted reporting acute left flank pain with scars on the mucous face of his prepuce and had a recent previous hospitalization for the same reason...

Maximizing the reproductive potential of ladybird beetles fed factitious foods or artificial diets, in lieu of natural prey, is a major challenge to cost-effective mass rearing for augmentative biological control. In this study, we tested the hypothesis that compounds in redcedar, Juniperus virginiana , stimulate oviposition in the ladybird Coleomegilla maculata . We also tested the prediction that several bioflavonoids, identified in heartwood fractions, elicited this behavioral response. Phenolic compounds were extracted from J...
