BACKGROUND The eccrine carcinoma is a rare form of skin adnexal malignancy, usually presenting as a locally invasive, solitary lesion in the head and neck region. Histopathologically and immunohistochemically, eccrine carcinomas are difficult to differentiate from cutaneous metastases of breast carcinomas. Unlike treatment of cutaneous metastasis, treatment of a solitary eccrine carcinoma entails excision, generally without systematic therapy. CASE DESCRIPTION A seventy-year-old woman previously treated definitively for (in situ) breast cancer, undergoes excision of a nodule on the scalp. The histopathology report indicates a lesion typical for cutaneous metastasis of breast carcinoma. However, diagnostic imaging excludes recurrent breast cancer or metastatic spread. When subsequent clonality testing with archived breast cancer tissue from the earlier episode does not show a relation, the pathologist defines the lesion as an eccrine carcinoma. A re-excision is conducted, which does not show any residual tumorous tissue, and at follow-up there are no signs of recurrence or metastases. CONCLUSION As a relatively rare and unknown malignancy, with strong histopathological resemblance to cutaneous metastasis of breast carcinoma, eccrine carcinoma poses a diagnostic challenge to both clinicians and pathologists.A 13-year-old boy was seen with symmetric bilateral swelling around the proximal interphalangeal joints. He did not have pain or loss of function or other signs of arthritis. Inflammation parameters and rheumatologic markers were negative. X-ray and MRI revealed soft tissue swelling. This confirmed the diagnosis pachydermodactyly, a rare benign form of fibromatosis.Diagnosis of systemic autoimmune diseases, including systemic lupus erythematosus (SLE), can be supported by detection of antinuclear antibodies (ANA). Additional support may be provided by detecting antibodies against double-stranded (ds) DNA, standard extractable nuclear antigens (ENA) or certain disease-specific antigen combinations, including a myositis panel for idiopathic inflammatory myopathy (IIM). The detection of ANA has classically been effected by indirect immunofluorescence (IIF) analysis of patient serum using HEp-2 cells. Although this method of ANA testing can be highly sensitive for systemic autoimmune disease, its specificity is restricted as ANA occurs in subjects with a variety of other conditions as well as in healthy subjects. Consequently, ANA testing by HEp-2 IIF should only be performed when sufficient relevant clinical suspicion is present, to avoid false-positive results. For some systemic autoimmune diseases, including Sjögren's syndrome and IIM, classical ANA testing is less sensitive and direct testing of antibodies against a standard ENA or a myositis panel, respectively, can be more successful to find autoantibodies.BACKGROUND Subacute hemichorea-hemiballismus in an older patient can be induced by non-ketotic hyperglycaemia. The triad of onset of subacute hemichorea-hemiballismus, hyperglycaemia and hyperdensity in the contralateral putamen on a CT scan or hyperintensity on a T1-weighted MRI scan is pathognomic for this diagnosis. Close observation of the motor restlessness and knowledge of this triad are important for making this diagnosis. CASE DESCRIPTION A 92-year-old female patient was admitted to the accident and emergency department with a history of motor restlessness for the past few days, confused speech and a glucose level of 20.5 mmol/l. Delirium was initially suspected. Abnormalities on the CT scan were indicative of hemichorea-hemiballismus caused by hyperglycaemia. The patient recovered fully once euglycaemic levels were restored. CONCLUSION Hemichorea-hemiballismus is a rare motor disorder, often due to an infarct in the contralateral basal ganglia. It can, however, be an expression of non-ketotic hyperglycaemia. The condition is sometimes confused with the motor restlessness of delirium.OBJECTIVE Tumor cells could acquire drug resistance through cell autophagy. This study aimed to explore the role of SNHG16 in sorafenib-resistant HCC cells and its mechanism with miR-23b-3p. METHODS The sorafenib-resistant Hep3B cell model was established. The SNHG16 and miR-23b-3p gene expressions were determined in normal HCC and sorafenib-resistant HCC tissues. Detection of the expression of SNHG16 and miR-23b-3p and its respective correlation with survival rate were performed. Target genes to SNHG16 and miR-23b-3p were predicted, and verified by dual-fluorescent reporter assay. The effects of SNHG16 and miR-23b-3p on SNHG16, miR-23b-3p, EGR1 expression, viability, apoptosis as well as LC3II/LC3 expression in Hep3B and Hep3B/So cells were detected by qRT-PCR, CCK-8, flow cytometry, and western blot. In in vivo studies, the NOD/SCID mice model was established to explore the effects of Hep3B and Hep3B/So cells with inhibited SNHG16 or miR-23b-3p on tumor size, EGR1 expression, and autophagy. RESULTS High SNHG16 expression in HCC-resistant tissues and low miR-23b-3p expression in all HCC tissues were detected, and the two were negatively correlated. Low SNHG16 and high miR-23b-3p were related to a high survival rate of HCC patients. selleck chemicals Moreover, SNHG16 overexpression promoted Hep3B/So cell viability and autophagy, suppressed apoptosis by inhibiting miR-23b-3p expression through up-regulating EGR1, however, the effect of si-SNHG16 was opposite. In in vivo studies, miR-23b-3p inhibitor suppressed the high sorafenib sensitivity in Hep3B/So cells caused by SNHG16 silencing through promoting viability, autophagy, and suppressing apoptosis. CONCLUSION SNHG16 promotes Hep3B/So cell viability, autophagy, and inhibits apoptosis to maintain its resistance to sorafenib through regulating the expression of miR-23b-3p via sponging EGR1. © 2020 The Authors.

Hydrogels providing a chondroregeneration-permissive environment are often mechanically weak and display poor lateral integration into the surrounding cartilage. This study develops a visible-light responsive gelatin ink with enhanced interactions with the native tissue, and potential for intraoperative bioprinting. A dual-functionalized tyramine and methacryloyl gelatin (GelMA-Tyr) is synthesized. Photo-crosslinking of both groups is triggered in a single photoexposure by cell-compatible visible light in presence of tris(2,2'-bipyridyl)dichlororuthenium(II) and sodium persulfate as initiators. Neo-cartilage formation from embedded chondroprogenitor cells is demonstrated in vitro, and the hydrogel is successfully applied as bioink for extrusion-printing. Visible light in situ crosslinking in cartilage defects results in no damage to the surrounding tissue, in contrast to the native chondrocyte death caused by UV light (365-400 nm range), commonly used in biofabrication.selleck chemicals
