General control non-derepressible 2 (GCN2) in T cells controls disease progression of autoimmune neuroinflammation.

2016

Relapsing-remitting multiple sclerosis (MS)(2) is characterized by phases of acute neuroinflammation followed by spontaneous remission. Termination of inflammation is accompanied by an influx of regulatory T cells (Tregs).(3) The molecular mechanisms responsible for directing Tregs into the inflamed CNS tissue, however, are incompletely understood. In an MS mouse model we show that the stress kinase general control non-derepressible 2 (GCN2),(4) expressed in T cells, contributes to the resolution of autoimmune neuroinflammation. Failure to recover from acute inflammation was associated with reduced frequencies of CNS-infiltrating Tregs. GCN2 deficient Tregs displayed impaired migration to a…

Spontaneous Remission of Recalcitrant Warts in Girls After Human Papillomavirus Vaccination

Clinical course and symptomatic prediagnostic period of patients with Wegener's granulomatosis and microscopic polyangiitis.

1998

The clinical course of 15 patients with Wegener's granulomatosis (WG) and eight patients with microscopic polyangiitis (MPA) from one nephrological clinical center is presented for the period from 1984 to 1993, when testing for antineutrophil cytoplasmic antibodies (ANCA) was gradually introduced into routine clinical practice. We found a high degree of prolonged time periods with symptoms attributable to WG or MPA until the specific diagnosis was made. Nine patients with WG and one patient with MPA had symptomatic prediagnostic periods of more than three years, which extended in one case up to twenty years. In these prediagnostic periods, often even severe flares of vasculitic activity res…

Clinical Characteristics, Treatment, and Evolution of 89 Mucoceles in Children

2009

Purpose The present study was undertaken to evaluate mucoceles in the oral cavity of pediatric patients, including the clinical characteristics, treatment, and progress of the lesions. Patients and Methods A retrospective study was performed from the medical records of patients (0-14 years old) treated for oral mucoceles between 1998 and 2008 in a reference children's hospital. All subjects with mucoceles on lips, mouth, buccal mucosa, and palate were included. The following data were recorded: age, gender, history of trauma, location, size, progression, time before diagnosis, treatment, histologic type, follow-up time, and recurrence. Results A total of 89 patients (mean age, 6.1 years) pa…

Experimental Hepatitis

1994

Publisher Summary This chapter presents the animal models of experimental hepatitis (EAH). EAH was developed as a model of human autoimmune hepatitis (AIH). AIH in humans is a heterogeneous disease, which most often occurs in young females and generally responds very well to immunosuppressive therapy. AIH is often not recognized or is misdiagnosed as chronic non-A, non-B (non-C) viral hepatitis. Even when left untreated for considerable time periods, the disease in some patients is moderate to mild, and transient spontaneous remissions can be observed. EAH in many ways reflects this disease process. EAH also is often mild to moderate, and spontaneous remission occurs. Autoantibodies are cri…

Parvovirus B19-Associated Microvesicular Eruption

2015

We report on a 3-year-old girl with a microvesicular generalized rash in whom primary infection by parvovirus B19 was demonstrated by seroconversion. To our knowledge, this is the first instance of an eruption arising from parvovirus B19 with this peculiar clinical pattern.

Traumatic neuroma of the mandible: a case report with spontaneous remission

2014

Traumatic neuroma is a well-known disorder involving peripheral nerves, which occurs following trauma or surgery. The lesion develops most commonly in the soft tissues of the mental foramen area, lower lip and tongue. Intra-osseous lesions arising in jawbones are very uncommon. In this paper, we report a new case of an intra-osseous traumatic neuroma, discovered incidentally on a panoramic radiograph obtained for orthodontic documentation. In addition, the case herein described developed spontaneous remission, a situation not previously reported in the literature. Finally, we discuss relevant demographic, clinical, microscopic, immunohistochemical and treatment aspects of traumatic neuromas…

Clinical Syndromes, Pathogenesis, and Differential Diagnosis

1991

The temporal sequence of signs and symptoms in patients with cerebral ischemia provides important information for the analysis of underlying pathophysiologic mechanisms and in the search for a major hemodynamic or embolic cause. The signs reported and symptoms assessed are useful for localization of the ischemic region of the brain and identification of the affected vascular territories. Even in the case of a typical clinical picture the clinical findings alone are often insufficient for unequivocal anatomic and pathologic identification, however important they may be in the choice of diagnostic and therapeutic measures. In the first few hours after cerebral ischemia, determining the progno…
