BACKGROUND: Scleroderma is a chronic connective tissue disorder with unknown etiology. It is characterized by excessive deposition of extracellular matrix in the connective tissues causing vascular disturbances which can result in tissue hypoxia. These changes are manifested as atrophy of the skin and/or mucosa, subcutaneous tissue, muscles, and internal organs. Such changes can be classified into two types, namely, morphea (localized) and diffuse (systemic). Morphea can manifest itself as hemifacial atrophy (Parry-Romberg syndrome) although this remains debatable...

Juvenile systemic lupus erythematosus (JSLE) is a complex multisystemic autoimmune disorder of unknown cause. It accounts for about one in five cases of SLE. The tendency for SLE to run a fulminant course when it starts in childhood has made JSLE a potentially more severe disease than adult SLE. Reports of JSLE from sub-Saharan Africa are scanty in spite of the increasing reports of adult SLE. We conducted a 4-year retrospective study of JSLE cases seen at the Lagos State University Teaching Hospital between January 2010 and December 2014...

The IIF using the HEp-2 cell substrate should be still considered the "gold standard" techniques for determination of antinuclear antibody (ANA). Standardization and automation can be considered to be still in progress. Aim of this study was to evaluate the performance of the commercially automated indirect immunofluorescent antinuclear HEp-2 antibody assay. The study was designed to compare two commercially available HEp-2 ANA by indirect immunofluorescent antibody assays using a sensitivity panel (120 clinically determined patients) and a specificity panel consisting of 78 clinically confirmed negative patients...

Small-fiber polyneuropathy (SFPN) causes non-specific symptoms including chronic pain, cardiovascular, gastrointestinal, and sweating complaints. Diagnosis is made from history and exam in patients with known risk factors such as diabetes, but objective test confirmation is recommended for patients without known risks. If tests confirm SFPN, and it is "initially idiopathic" (iiSFPN), screening for occult causes is indicated. This study's aim was to evaluate the 21 widely available, recommended blood tests to identify the most cost-effective ones and to learn about occult causes of iiSFPN...

A 71-year-old woman with arthralgia and lung fibrosis was referred to Mito Kyodo General Hospital (Mito, Japan) for a mass, which was incidentally observed on a chest radiograph. The chest computed tomography scan demonstrated fibrotic lesions in the lower lobes of the lung and a nodule in the left upper lobe. The serum levels of myeloperoxidase (MPO)-anti-neutrophil cytoplasmic antibody (ANCA) and proteinase 3 (PR3)-ANCA were 60.3 and 7.5 U/ml, respectively. A transbronchial biopsy obtained from the nodule in the left upper lobe of the lung revealed a lung adenocarcinoma and the patient underwent standard upper lobectomy of the left lung...

Lichen sclerosus is a chronic inflammatory disease associated with substantial morbidity. Knowledge of the aetiology and progression of lichen sclerosus is therefore needed. In this cross-sectional study, 100 male patients diagnosed with lichen sclerosus were interviewed and examined. Since there is a possible link between lichen sclerosus and autoimmunity, blood tests were analysed for thyroid disease, antinuclear antibodies and antibodies to extracellular matrix protein 1, but autoimmunity was found to be infrequent...
