BACKGROUND. Schwartz-Jampel syndrome is a rare disorder inherited as an autosomal recessive trait and characterized by growth retardation, multiple skeletal abnormalities, myotonia-like muscle disorders and unusual facies. CASE REPORTS. Case n. 1: A boy, aged 3 years 4 months, was admitted for acute respiratory disease. His main abnormalities included rigid facial expression, blepharophimosis, puckered lips, short neck, pectus carinatum, acetabular dysplasia with coxa vara, platyspondyly and marked growth retardation. There was a continuous muscle fiber activity at rest, with abnormal discharges originating in the muscle component of the neuromuscular junction. Blood investigations revealed low values of IgA. The child died at 4 years. Case n. 2: The sister of case n. 1 was examined at 14 months of age. She presented milder facies abnormalities, difficulties of gait because of stiff hips, muscular hypertrophy, coxa vara and growth retardation. X-rays showed skeletal abnormalities and the electromyogram was similar to those of her brother. She had dislocation of her optic lens. CONCLUSION. These 2 sibs have the characteristic manifestations of Schwartz-Jampel syndrome. Parental consanguinity was also present. The IgA deficiency observed in case n. 1 and the lens dislocation in case n. 2 have both been occasionally reported in this syndrome. 相似文献

Histiocytic necrotizing lymphadenitis, also known as KIKUCHI disease is rare self-limited condition of young adults. Manifestations include enlargements of the cervical lymph nodes, sometimes with fever, and can be associated with other non-specific signs. The aetiologie of this affection is still unclear. This is a case report of a 27 year-old man who presented cervical and sus-clavicular lymphadenopathy diagnosed first as lymph nodes tuberculosis before the diagnostic of KIKUCHI disease was made. 相似文献

Simultaneous inhibition of IL4 and IL13 via the common receptor chain IL4Rα to block adequately their biologic effects presents a promising therapeutic approach to give the additional relief required for asthma patients. In this study, superparamagnetic iron oxide nanoparticles were conjugated with anti‐IL4Rα blocking antibodies via polyethylene glycol (PEG) polymers. The delivery of these blocking antibodies to the inflammatory sites in the lung via the developed nanocarriers was assessed using noninvasive free‐breathing pulmonary MRI. Biocompatibility assays confirmed the safety of the developed nanocarriers for pre‐clinical investigations. For all the investigated formulations, nanocarriers were found to be very stable at neutral pH. However, the stability noticeably decreased with the PEG length in acidic environment and thus the loaded antibodies were preferentially released. Immunofluorescence and fluorimetry assays confirmed the binding of the nanocarriers to the IL4Rα asthma biomarker. Pulmonary MRI performed using an ultra‐short echo time sequence allowed simultaneous noninvasive monitoring of inflammatory responses induced by ovalbumin challenge and tracking of the developed nanocarriers, which were found to colocalize with the inflammatory sites in the lung. Targeting of the developed nanocarriers to areas rich in IL4Rα positive inflammatory cells was confirmed using histological and flow cytometry analyses. The anti‐IL4Rα‐conjugated nanocarriers developed here have been confirmed to be efficient in targeting key inflammatory cells during chronic lung inflammation following intrapulmonary administration. Targeting efficiency was monitored using noninvasive MRI, allowing detection of the nanocarriers’ colocalizations with the inflammatory sites in the lung of ovalbumin‐challenged asthmatic mice.

Background and aimsImmigrant women from the Middle East have higher cardiovascular risk compared to native women. Whether low antioxidant intake, oxidative stress or inflammation contributes to risk is unknown. In a cross-sectional study of 157 randomly selected foreign-born women (Iranian and Turkish) and native women living in Sweden, we investigated antioxidant status, oxidative stress (F2-isoprostanes) and systemic inflammation (plasma high sensitive C-reactive protein; CRP) markers. We also investigated relationships between F2-isoprostanes, CRP and cardiovascular risk factors.Methods and resultDietary intake was assessed using 24-h dietary recalls repeated four times. Micronutrient intake was not consistently different between groups. Serum α-tocopherol, but not γ-tocopherol levels, was lower in Turkish vs. Swedish women (P < 0.05). Turkish women had the highest F2-isoprostane levels (P < 0.05 vs. Iranian women) and CRP levels (P < 0.01 vs. Swedish women and P = 0.05 vs. Iranian women). In immigrants (n = 97), F2-isoprostanes correlated positively to insulin levels (r = 0.31, P < 0.01), and CRP was correlated to obesity and several cardiovascular risk factors (r-values >0.21, P values <0.05).ConclusionThe role of antioxidant status is unclear, whereas signs of oxidative stress and inflammation are evident in immigrant women from Middle East, especially Turkish women. Oxidative stress and low-grade inflammation might contribute to the higher cardiovascular risk previously observed in immigrant women. Further larger studies adjusting for more potential confounders are motivated to confirm these results. 相似文献
