Alveolar cleft reconstruction has historically relied on autologous iliac crest bone grafting (ICBG), but donor site morbidity, pain, and prolonged hospitalization have prompted the search for bone graft substitutes. The authors evaluated bone graft substitutes with the highest levels of evidence, and highlight the products that show promise in alveolar cleft repair and in maxillary augmentation. This comprehensive review guides the craniofacial surgeon toward safe and informed utilization of biomaterials in the alveolar cleft.

Dapsone-induced hypersensitivity reactions may cause severe cutaneous adverse reactions (SCAR), such as drug reaction with eosinophilia and systemic symptoms (DRESS). It has been reported that HLA-B*13:01 is strongly associated with dapsone-induced hypersensitivity reactions among leprosy patients. However, the phenotype specificity and detailed immune mechanism of HLA-B*13:01 remains unclear.

Lichen myxedematosus is condition characterized by localized areas of dermal deposition of mucin, presenting with firm papules localized to few areas of the body. The condition needs to be excluded from scleromyxedema, which, in addition to the firm papular eruption, has areas of induration and is usually associated with a monoclonal gammopathyand systemic symptoms. We present a 62-year-old woman with a several-year history of asymptomatic, firm papules over the face and arms with no evidence of thyroid disease or a monoclonal gammopathy,which is consistent with a diagnosis of localized lichen myxedematosus, the discrete papular variant.

Explosive super-eruptions can erupt up to thousands of kmof magma with extremely high mass flow rates (MFR). The plume dynamics of these super-eruptions are still poorly understood. To understand the processes operating in these plumes we used a fluid-dynamical model to simulate what happens at a range of MFR, from values generating intense Plinian columns, as did the 1991 Pinatubo eruption, to upper end-members resulting in co-ignimbrite plumes like Toba super-eruption.

Recent measurements of cosmic-ray (CR) light nuclei by AMS-02 have shown that there is an unexpected component of CR lithium whose spectral index is harder than that expected from the secondary production scenario. We propose the nearby type Ia supernova following a nova eruption as the origin of lithium nuclei in the CRs. By fitting the data of CR protons, helium, and lithium fluxes provided by AMS-02 with our theoretical model we show that this scenario is consistent with the observations.

Animal studies suggest that the dental follicle (DF) plays a major role in tooth eruption. However, the role of the DF during tooth impaction and related root resorptions in adjacent teeth is not clear. The hypothesis for the present study is that expression of regulatory factors involved in the bone remodelling process necessary for tooth eruption may differ between dental follicles from teeth with different clinical situations.

Polymorphic light eruption (PLE) is the most common autoimmune photodermatosis. Plasmacytoid dendritic cells (PDCs) are important mediators of innate anti-microbial immunity involved in the pathogenesis of many inflammatory skin diseases. In addition to PDCs, regulatory T cells (Tregs) are involved in controlling inflammation and adaptative immunity in skin by their immunosoppressive capacity.

We report two rare cases of childhood epilepsy patients who developed ethosuximide-induced Stevens-Johnson syndrome (SJS). Unlike typical SJS, the initial eruption of both patients presented well-demarcated, infiltrating firm papules mainly on the cheeks and the extensor aspects of the arms (case 1), and multiple vesicles on the soles and oral aphthosis (case 2), which closely mimicked viral exanthema. We diagnosed both patients with ethosuximide-induced SJS, based on the dosing period and the positive results of drug-induced lymphocyte stimulation test.

Maintenance of primary dentition is imperative for the development of arch form, esthetics, function, mastication, and normal eruption of permanent teeth. Premature loss can cause various problems such as ectopic eruption, space loss for the successor permanent teeth, alterations in speech, and impairment of function. Hence, decayed primary teeth should not be extracted and treated whenever possible.

Solar flares are spectacular coronal events that release large amounts of energy. They are classified as either eruptive or confined, depending on whether they are associated with a coronal mass ejection. Two types of model have been developed to identify the mechanism that triggers confined flares, although it has hitherto not been possible to decide between them because the magnetic field at the origin of the flares could not be determined with the required accuracy.

Human T-lymphotropic virus type 1 (HTLV-1) causes the debilitating neuroinflammatory disease HTLV-1-associated myelopathy-tropical spastic paraparesis (HAM-TSP) as well as adult T-cell leukemia-lymphoma (ATLL). In patients with HAM-TSP, HTLV-1 infects mainly CCR4+ T cells and induces functional changes, ultimately causing chronic spinal cord inflammation. We evaluated mogamulizumab, a humanized anti-CCR4 monoclonal antibody that targets infected cells, in patients with HAM-TSP.

Skin wound healing has been widely studied in mammalian models but the information on teleost cutaneous healing is sparse and frequently considered in the context of viral or bacterial infections or parasitic infestations in aquaculture. In the present study a detailed time course (0 h, 6 h, 1, 2, 3 and 4 days) coupled to morphology and gene expression analysis revealed rapid regeneration of skin without scarring in a marine teleost after a superficial wound caused by the loss of a large area of scales. The integrity of the integument, as assessed by quantification of extracellular matrix (ECM) gene transcripts (fn1a, colIα1, colVα2, colXα1, ogn1, ogn2, crtac1a, cyr61, pcna, krt2 and mmp9) was restored within 2 days.
