We present an unusual case of liver involvement in monoclonal gammopathy with generalized crystal-storing histiocytosis (G-CSH).A bone marrow storage disease was diagnosed in a 79-year-old man with monoclonal gammopathy of uncertain significance (MGUS). The patient presented with pleural effusion, an osteolytic lesion of the humerus, and an increase of aspartate transaminase and cholestatic markers that raised the clinical suspect of liver disease. A second bone marrow biopsy confirmed the diagnosis of MGUS with a histiocytic component suggestive for G-CSH.Liver biopsy showed an unremarkable histology, no significant inflammatory infiltrates, and intrasinusoidal foamy histiocytes. PAS and Masson's trichrome stains, showed, in the cytoplasm of both histiocytes and hepatocytes, rod-shaped eosinophilic crystals, which were immunoreactive for kappa light chains. Transmission electron microscopy performed on reprocessed histological sections confirmed the presence of crystals in the hepatocyte cytoplasms. Immunogold labeling intensely stained crystals for kappa light chains.To the best of our knowledge, this is the second case in which an intrahepatocellular crystal storage is described during liver involvement in G-CSH. The present case also suggests that an increase in liver serum enzymes may support the clinical diagnosis of liver CSH in a patient with MGUS.Purpose of the article. To explore the role of fetal echocardiography in predicting the risk of urgent balloon atrial septostomy (BAS) at birth in fetuses diagnosed with transposition of the great arteries (TGA).Material and methods Medline, Embase, and Cochrane databases were searched. The primary aim was to explore the differences in prenatal echocardiographic parameters among fetuses diagnosed with TGA that required urgent BAS within 24 h of birth due to life-threatening cyanosis compared to those who did not require such procedure. Random-effect meta-analyses were used to compute the data.Results Six studies (292 fetuses) were included. Restrictive appearance of the FO was present in 64.5% (95% CI = 39.8-85.7) of fetuses with TGA requiring BAS at birth compared to 7.9% (95% CI = 2.1-16.8) not requiring such procedure (OR = 71.1; 95% CI = 8.3-608.5, p  less then  .0001). Hypermobile appearance of the atrial septum was present in 39.1% (95% CI = 26.4-56.5) of fetuses requiring BAS at birth compared to 9.8% n stratify the risk of BAS in fetuses with TGA. Further studies are needed to validate these findings and build individualized multiparametric predictive models in order to more accurately identify those fetuses with TGA at a higher risk of urgent BAS after birth.Lipopolysaccharide (LPS) is an endotoxin that prompts neuroinflammation and initiates neurodegenerative disorders. Exosome is a recent therapeutic agent for many diseases such as neurological diseases. This study aimed to evaluate the potential protective role of bone marrow mesenchymal stem cell-derived exosomes (BMSC-EXs) in cerebellar cortex LPS-induced neuroinflammation in rats. Twenty-seven adult male rats were divided into three groups Group I control rats; Group II LPS-treated rats; Group III LPS/BMSC-EXs-treated rats. Cerebellar specimens were taken and processed for histological and immunohistochemical analysis. Morphometrical studies and statistical analysis were done. Groups II showed neuronal degeneration and apoptosis. The mean number of Purkinje cells was significantly (P less then 0.01) decreased, while glial fibrillary acidic protein (GFAP) immunoexpression was significantly increased in the neuroglial cells. NSC 649890 chemical structure Ultrastructural examination showed shrunken Purkinje cells with irregular nuclei and disrupted mitochondria. Group III showed improvement of most of the changes mentioned previously. EXs therapy is a promising neuroprotective tool for treatment of LPS-induced neuroinflammation.Background Little is known regarding the long-term outcomes of offsprings to non-diabetic mothers with family history of diabetes mellitus (FHDM).Objective The aim of the study was to determine whether being born to a non-diabetic mother with FHDM increases the risk for long-term endocrine morbidity.Methods This is a population-based cohort study, comparing long-term endocrine morbidity between offspring born to non-diabetic mothers with and without FHDM. The Kaplan-Meier survival curve was used to compare cumulative morbidity incidence. Cox proportional hazards model was performed to control for confounders.Results During the study period, 208,728 children met the inclusion criteria. Using a Kaplan-Meier survival curve, offspring born to non-diabetic mothers with a FHDM had higher cumulative incidence of endocrine morbidity compared to their counterparts without FHDM (Log rank test p = .014). Using a Cox model, controlling for confounders, being born to a non-diabetic mother with FHDM was an independent risk factor for long-term endocrine morbidity of the offspring (adjusted HR = 1.24, 95%CI 1.001-1.54; p = .043).Conclusion Being born to a non-diabetic mother with a FHDM is independently associated with higher risk for long-term endocrine morbidity of the offspring.Osteopontin (OPN) is involved in the atherosclerotic and inflammatory process. In this article, we examined the relationship between circulating OPN levels with lower extremity arterial disease (LEAD) in individuals with type 2 diabetes mellitus (T2DM). Seventy individuals with T2DM and 66 individuals without T2DM were recruited. Diagnosis of LEAD was based on the absence of triphasic waveform on the pedal arteries. Plasma OPN levels were determined by Luminex Multiplex immunoassay. LEAD was present in 34 (48.6%) patients with T2DM. In the diabetes cohort, individuals with LEAD had higher plasma OPN concentrations than those without LEAD (geometric mean [95% confidence intervals]; 43.4 [37.5-50.4] vs 26.1 [22.9-29.8] ng/mL, respectively, P less then .001). Multivariable analysis showed that presence of LEAD independently associated with higher OPN levels in subjects with T2DM, with marginal statistical significance (P = .049). In both cohorts, plasma OPN concentrations were negatively associated with ankle-brachial index values (P less then .
