BACKGROUND: The cytology of oral squamous cell carcinoma (SCC) is challenging because oral SCC cells tend to be well differentiated and lack nuclear atypia, often resulting in a false negative diagnosis. The purpose of this study was to establish practical cytological parameters specific to oral SCCs. METHODS: We reviewed 123 cases of malignancy and 53 of non-neoplastic lesions of the oral mucosa, which had been diagnosed using both cytology and histopathology specimens...

This is the first reported study of children's use of two metacognitive strategies, recollection rejection and diagnostic monitoring, to reject misinformation. Recollection rejection involves the retrieval of details that disqualify an event, whereas diagnostic monitoring involves the failure to retrieve expected details. First (n = 56, age 7 years) and third graders (n = 52, age 9 years) witnessed a staged classroom interaction involving common and bizarre accidents, were presented with misinformation about the source of these events, and took a memory test...

BACKGROUND: Arthropod diversity is unparalleled in the animal kingdom. The study of ontogeny is pivotal to understand which developmental processes underlie the incredible morphological disparity of arthropods and thus to eventually unravel evolutionary transformations leading to their success. Work on laboratory model organisms has yielded in-depth data on numerous developmental mechanisms in arthropods. Yet, although the range of studied taxa has increased noticeably since the advent of comparative evolutionary developmental biology (evo-devo), several smaller groups remain understudied...

Giant cell ependymomas (GCE) are extremely rare tumors, with 24 cases described in the literature. Squash cytology is a rapid, reliable, simple technique for intraoperative consultation in neurosurgical practice. We describe a rare case of GCE arising at level of L4-L5 in a 66-year-old woman and discuss the cytologic/histologic features. Intraoperative smears were highly cellular with a prominent fibrillary background and exhibited papillary structures and sheets composed of highly atypical and bizarre cells...

Animal life in caves has fascinated researchers and the public alike because of the unusual and sometimes bizarre morphological adaptations observed in numerous troglobitic species. Despite their worldwide diversity, the adaptations of cave millipedes (Diplopoda) to a troglobitic lifestyle have rarely been examined. In this study, morphological characters were analyzed in species belonging to four different orders (Glomerida, Polydesmida, Chordeumatida, and Spirostreptida) and six different families (Glomeridae, Paradoxosomatidae, Polydesmidae, Haplodesmidae, Megalotylidae, and Cambalopsidae) that represent the taxonomic diversity of class Diplopoda...

BACKGROUND: Tumor lysis syndrome can occur after treatment of fast-growing cancers. Early detection of tumor lysis is crucial to minimize the toxic effects on organs and potentially life-threatening complications. METHODS: A patient with acute monocytic leukemia presented with spurious thrombocytosis. A peripheral blood smear was stained with alpha-naphthyl butyrate esterase to discriminate tumor cell fragments from platelets. RESULTS: Peripheral blood smears showed widespread leukemic cell fragmentation...

AIM: The aim of this study was the characterization of a new subtype of high-grade cervical squamous intraepithelial lesion (HSIL) with enlarged cells containing bizarre nuclei: so-called bizarre cell dysplasia (BCD). METHODS: A total of 29 cervical cone biopsy samples of this type of dysplasia were studied. Multi-target polymerase chain reaction and in situ hybridization human papillomavirus (HPV) detection was performed in all cases. BCD was defined as a subtype of HSIL characterized by the presence of large dysplastic cells with abnormal, large pleomorphic nuclei or multinucleation causing nucleomegaly...

Chronic hyponatremia is very rare in children and is often seen in the setting of congestive heart failure or liver failure in adults. Here, we report an 8-year-old child with hypothalamic glioma who presented with severe hyponatremia. Initial management consisted of fluid restriction. This was very difficult for the child to follow and the child developed bizarre drinking habits requiring intervention from child psychiatry. So therapy was initiated with low dose V2 receptor antagonist under close inpatient monitoring...

Enantiornithes are the most successful clade of Mesozoic birds. Here, we describe a new enantiornithine bird, Cruralispennia multidonta gen. et sp. nov., from the Protopteryx-horizon of the Early Cretaceous Huajiying Formation of China. Despite being among the oldest known enantiornithines, Cruralispennia displays derived morphologies that are unexpected at such an early stage in the evolution of this clade. A plough-shaped pygostyle, like that of the Ornithuromorpha, evolved convergently in the Cruralispennia lineage, highlighting the homoplastic nature of early avian evolution...

INTRODUCTION: Local recurrence of prostate cancer (PCa) following radiotherapy may be treated with curative intent using salvage high-intensity focused ultrasound (s-HIFU). The interpretation of needle core biopsy specimens following s-HIFU is a daunting task, even for experienced pathologists. We describe various histopathological features encountered in biopsy specimens following whole-gland s-HIFU in one of the largest descriptive studies to date. METHODS: Fifty-five patients with biopsy-proven localized radio-recurrent PCa underwent s-HIFU and transrectal ultrasound (TRUS)-guided prostatic needle biopsies at 180 days post-treatment...

Behçet disease (BD) is a multisystem disorder, with vasculitis as its underlying pathological process, in contrast to the classic triad of recurrent oral and genital ulcerations, with uveitis. Vascular involvement in BD includes venous thrombosis, arterial occlusion, and pulmonary artery and aortic aneurysm formation. Cardiac involvement is rare and often obscure. It includes intracardiac thrombi formation, and is associated with a poor prognosis. Our objectives are to describe two cases with BD, complicated with vascular and cardiac involvement, and to raise awareness of these rare complications, the needed routine surveillance, and thus to prevent inappropriate interventions, serious outcomes, and mortality...

Paolo Tinuper, Francesca Bisulli
Nocturnal frontal lobe epilepsy (NFLE) is a focal epilepsy with seizures arising mainly during sleep and characterized by complex, often bizarre, motor behavior or sustained dystonic posturing. First described in 1981, it was initially considered a motor disorder of sleep and was named nocturnal paroxysmal dystonia (NPD). The unusual seizure semiology, onset during sleep, and often uninformative scalp EEG and brain MRI make it difficult to distinguish NPD attacks from other non-epileptic nocturnal paroxysmal events, namely parasomnias...

Patients with advanced chronic kidney disease including ESRD patients may present with a wide spectrum of cutaneous abnormalities, ranging from xerosis to hyperpigmentation to severe deforming necrotizing lesions. Skin problems are not uncommon in this population of patients, with a clinical presentation that can be quite bizarre, mandating a long list of differential diagnostic possibilities, and subsequent rise of a puzzling diagnostic challenge. We describe an ESRD patient who presented with blistering, nonhealing ulcerative lesions with a diagnostic skin biopsy revealing a mixed pattern of linear IgA bullous dermatosis and dermatitis herpetiformis...

In this paper fascination phenomenologically is described as a state of radically being captured by an imposing object. What is left of the impoverished and paralysed subject clings to the exclusive fascinating object. Fascination is the eye of the storm of extreme ambivalence towards an exclusive object: being the only remaining object it is necessary for living in an object world, but at the same time it is threatening to life by absorbing the subject totally. So the subject is sucked in by a yet frightening object...

AIM: Few studies have investigated Internet Addiction (IA) in adolescents in relation to personality characteristics. The aim of this study was to determine whether personality differences exist between adolescents with problematic/pathological Internet use and those with normal Internet use. Our hypothesis was that certain psychopathological personality traits may predispose to the development of maladaptive Internet use. METHODS: The Internet Addiction Test (IAT) and the Minnesota Multiphasic Personality Inventory-Adolescent (MMPI-A) were administered to a sample of 224 high school students...

OBJECTIVES: Considering that suicide is one of the most common reasons of adolescent death worldwide, there is a lack of clinical awareness on suicidal behaviors of children and adolescents with autism spectrum disorder (ASD). The present study aims to assess the rate of suicidality (suicidal ideation, behaviors and attempts) and associated risk factors for suicidality in high functioning ASD. METHODS: Medical records of 55 adolescents (six girls, 49 boys), aged between 7-20 years, with diagnosis of ASD were reviewed...

BACKGROUND: Cardiac tamponade is an emergency condition that requires early recognition and prompt pericardial decompression. Little has been reported on cardiac tamponade in liver retransplantation (reLT), but most cases are fatal. We managed a case of reLT complicated by accidental cardiac tamponade. CASE REPORT: A 59-year-old man underwent an emergency reLT because of liver cirrhosis with recurrent hepatitis B. During the dissection, suprahepatic exploration was attempted, but this resulted in severe hemorrhage because of the many tissue adhesions...
