    Chilblain, also known as pernio, is an abnormal inflammatory response to cold, moist environmental conditions. Persistent or atypical lesions should prompt investigation to exclude underlying systemic illness. We describe a case of acute myeloid leukaemia that presented with chilblain-like leukaemia cutis.

    Full Text Available Perniosis (chilblain is inflammatory cutaneous lesions located on acral surfaces (fingers, toes, nose, aurikula which present in association with cold exposure. They can appear as an idiopathic (primary dermatosis or with an underlying autoimmune disease (secondary. The primary or idiopathic form is not associated with an underlying disease and is clinically indistinguishable from the secondary form. The secondary form is associated with an underlying condition such as connective tissue disease, monoclonal gammopathy, cryoglobulinemia, or chronic myelomonocytic leukemia. Histopathology cannot accurately help distinguish the primary from secondary forms of chilblains. This review aims to raise the awareness of perniosis to avoid excessive investigation and anxiety and to help patients with only appropriate simple advice and treatment.

    Full Text Available Background. Application of various technological procedures for the manufacture of officinal preparation ointment against chilblains (Unguentum contra perniones produce essential variations in the quality and stability of the final product. Changing the sequence of admixing active substances into the ointment base indicated the presence of incompatibility between the active substances, as well as between the active substances and the ointment base components. The aim was to examine the influence of various technological manufacturing procedures on quality and stability of the preparation. Methods. Changes in the samples of ointments and aqueous solutions of active substances were analyzed microscopically. Results. Microscopic analysis of hydrosoluble active substance solutions demonstrated destruction of ichthammol, induced by an acidic medium due to the dissolution of tannin and resorcinol, which is well known from the literature. It also demonstrated the destruction of tannin and resorcinol in aqueous solution, which had not been described in the literature. Application of the prescribed procedure for the manufacturing of ointment against chilblains, conceals the incompatibility reactions due to a slow dissolution of the tannin suspended in the officinal ointment base Unguentum cera lanae. Admixture of an ready-made aqueous solution of tannin caused an instant contact between ichthammol and the acidic medium, which caused the destruction or the complete absence of the formation of emulsion droplets. The problem of incompatibility reactions between lanolin alcohols in the ointment base and ichthammol and resorcinol, as well as the reaction between Peruvian balsam and sulfur from the ichthammol sulfate ion was observed. Numerous incompatibility reactions of ointment against chilblains, components indicated that it was necessary to introduce alterations in both the qualitative and quantitative composition of the preparation. Conclusion. Excipient

    Full Text Available Calcium channel blockers are a group of drugs often used to treat cardiovascular diseases, such as hypertension, angina, peripheral vascular disorders and some arrhythmias. These drugs may suppress the growth and proliferation of vascular smooth muscle cells and fibroblasts, and inhibit the synthesis of extracellular-matrix proteins,such as collagen, fibronectin, proteoglycans. Some calcium channel blockers also have immunomodulatory or dysregulatory effects on lymphocytes and can suppress superoxide generation and phagocytic activity of neutrophils. Moreover, mast cell degranulation and platelet aggregation may also be impaired. On account of these properties, calcium channel blockers have also been used for the prevention and treatment of various dermatologic diseases. In this review, we evaluated the use of calcium channel blockers in various dermatologic diseases, such as Raynaud’s phenomenon, chilblains, chronic anal fissures, vulvodynia, keloids and burn scars, calcinosis cutis, and leiomyoma.

    Aicardi-Goutières syndrome is an inflammatory disease occurring due to mutations in any of TREX1, RNASEH2A, RNASEH2B, RNASEH2C, SAMHD1, ADAR or IFIH1. We report on 374 patients from 299 families with mutations in these seven genes. Most patients conformed to one of two fairly stereotyped clinical profiles; either exhibiting an in utero disease-onset (74 patients; 22.8% of all patients where data were available), or a post-natal presentation, usually within the first year of life (223 patients; 68.6%), characterized by a sub-acute encephalopathy and a loss of previously acquired skills. Other clinically distinct phenotypes were also observed; particularly, bilateral striatal necrosis (13 patients; 3.6%) and non-syndromic spastic paraparesis (12 patients; 3.4%). We recorded 69 deaths (19.3% of patients with follow-up data). Of 285 patients for whom data were available, 210 (73.7%) were profoundly disabled, with no useful motor, speech and intellectual function. Chilblains, glaucoma, hypothyroidism, cardiomyopathy, intracerebral vasculitis, peripheral neuropathy, bowel inflammation and systemic lupus erythematosus were seen frequently enough to be confirmed as real associations with the Aicardi-Goutieres syndrome phenotype. We observed a robust relationship between mutations in all seven genes with increased type I interferon activity in cerebrospinal fluid and serum, and the increased expression of interferon-stimulated gene transcripts in peripheral blood. We recorded a positive correlation between the level of cerebrospinal fluid interferon activity assayed within one year of disease presentation and the degree of subsequent disability. Interferon-stimulated gene transcripts remained high in most patients, indicating an ongoing disease process. On the basis of substantial morbidity and mortality, our data highlight the urgent need to define coherent treatment strategies for the phenotypes associated with mutations in the Aicardi-Goutières syndrome-related genes

    Full Text Available The emergence and spread of stress reactions are provided by the blood circulation system. In its turn, the adequacy of blood circulation depends on the hemorheological and vascular mechanisms. The changeability of their properties appears to be the basis of the increasing of stress stages. From the viewpoint of biophysical reactions, any change and movement occur with the expenditure and accumulation of energy. Higher level of adaptation energy waste and secondary level take place, when a small stressor entails a small expenditure. There is a maximum possible rate of adaptive energy consumption and at this maximum the organism cannot cope with any additional stimulus. At the same time adaptive and stress diseases develop. Let’s consider the duration and manifestation of Raynaud's disease from the perspective of adaptation diseases and diseases of the third grade, which appears to be the cause of the double stress effect - cold and emotional- physical and psychic. Total of 97 patients with Raynaud's disease were examined. For a new vision of the problem it was necessary to find out how the streessors of various nature impact the hemoreheological status and vascular resistance. For this purpose all the patients were examined for a resistance index of resistive arteries of the hand and the indices of erythrocyte aggregation and deformability. The patients were divided into four subgroups. The first subgroup – the patients after chilblain, the second subgroup – the patients with psychic strerssor, the third subgroup – the patients with prolonged chronic stress, and the fourth subgroup – the patients without the differentiation of the stressors. According to the obtained results, it is obvious that at cold and emotional stress (I and II subgroups the hemorheological and vascular parameters are changed. However, this change (hemorheological and vascular is more pronounced at chronic emotional stress (III subgroup as compared both to the

    8 cases of atrioventricular blockage (AVB) (3 degree Ⅰ , 3 degree Ⅱ and 2 degree Ⅲ ) and 5 cases of right bundle branch block cases (RBBB). Nine cases had anatomical abnormality including 5 cases of atrial septal defect (ASD), 2 cases of ventricular septal defect (VSD) and 2 cases of atrial enlargements. Forty-four cases had hematological problems including 28 with thrombocytopenia, 11 with leukocytopenia and 34 with anemia.Thirty cases had hepatic abnormality, including 24 liver dysfunction, 22 hepatomegaly, 6 splenomegaly and 3 cholestasis. Three cases had nephropathy; 3 had elevated creatine kinase; 2 had nervous disorder. Among the 94 cases, 86 (91.5%) were positive for anti-SSA, 51 (54. 3% ) anti-SSB, 16 anti-ds-DNA, 14 antiU1 -RNP, 13 anti-Sm ( + ), 6 anti-RNP and 4 anti-rRNP( + ). Among the corresponding mothers, 39 cases (44. 8% ) were asymptomatic before pregnancy, 35 had SLE, 5 had SCLE, 3 had Sjogren syndrome, 2 had chilblain, photosensitivity and arthralgia, respectively, 1 had rheumatoid arthritis and 1 had psoriasis.During pregnancy, 8 mothers developed SLE. Totally 48 mothers ( 51.1% ) suffered from LE. Together with 15 mothers who had transient skin rash during the pregnancy, there were 23 mothers (59%) who had new clinical manifestation among the 39 asymptomatic mothers. Twenty NLE cases accepted glucocorticoid treatment, 4 of them were treated with intravenous immunoglobulin. Sixty-eight cases were followed up for upto 12 years, 58 cases were healthy, 5 cases improved and 3 died. Two cases still had grade Ⅲ AVB without pacemaker. Conclusion NLE is a rare acquired autoimmune disease. Although nearly half of the mothers were asymptomatic before pregnancy, more than half of them developed LE or other symptoms. The clinical presentations in Chinese cases include a transient rash, cardiac lesion while grade Ⅲ AVB was rare,hematological changes and liver impairments which were common but not serious. Anti-SSA and/or anti-SSB were the most
