A 45-year-old man visited the first hospital complained of high fever on January 2003. He was diagnosed as having Influenza virus type A infection and prescribed of Oseltamivir. He was afebrile next day, but severe myalgia of neck, shoulder, lumbar region and right femoral region was appeared. His illness was considered as polymyalgia rheumatica and started of oral steroid therapy. His symptom was deteriorated and transferred to our hospital. Echography, Ga scintigraphy, computed tomography and magnetic resonance imaging revealed the multiple abscesses and the diagnosis of pyomyositis was made. Pyomyositis following Influenza virus infection must be considered as a differential diagnosis of myalgia after Influenza virus infection. 相似文献
Introduction:Malignant catatonia (MC) is a movement disorder syndrome characterized by immobility, rigidity, and consciousness disorders that develops in association with mental and physical diseases. It is often fatal due to hyperthermia, rhabdomyolysis, and acute kidney injury. Its clinical symptoms are similar to those of another disorder, neuroleptic malignant syndrome (NMS), and it is often difficult to distinguish between the 2 disorders.Patient concerns:An Asian woman in her 60s with history of schizophrenia. She was admitted to our hospital because of symptoms such as fever, unconsciousness, and muscle rigidity. Blood tests showed kidney injury and high creatinine kinase levels.Diagnoses:At the time of admission, she had been diagnosed with NMS complicated by pulmonary aspergillosis and was undergoing treatment although there was no improvement.Interventions:Subsequently, the administration of propofol, a gamma-aminobutyric acid A agonist, markedly improved the symptoms, and the diagnosis was corrected to MC. At the beginning of her hospitalization, she received dantrolene, bromocriptine, amantadine, and L-3,4-dihydroxyphenylalanine as treatment for NMS, but her symptoms did not improve. With propofol, which is used for sedation, her catatonic symptoms improved markedly. Quetiapine administration further improved the symptoms, and it eventually resolved completely.Outcomes:The patient''s MC was in remission. Prolonged intensive care management resulted in a decline in activities of daily living, and she required rehabilitation at another hospital.Conclusion:This is the first report of MC with suspected involvement of pulmonary aspergillosis. MC differs from NMS, in that it is treated more effectively with gamma-aminobutyric acid A agonists. Although benzodiazepines are the first choice for the diagnosis and treatment of MC, they are ineffective for majority of patients with schizophrenia. However, even in such cases, propofol and quetiapine are effective, and they facilitate diagnosis and treatment. 相似文献

A rare case of endescopic and histological regression of a gastric lymphoid mucosal lesion after eradication ofHelicobacter pylori is reported. A 72-year-old man was suspected of having a low-grade B-cell gastric mucosa-associated lymphoid tissue (MALT)
lymphoma by endoscopic and histological findings. Histology of biopsy specimens showed massive infiltration of atypical lymphocytes
and lymphoepithelial lesions. Immunohistochemical staining revealed kappa light chain expression in the infiltrated atypical
lymphocytes to be twofold that of lambda light chain. The above diagnosis was thus highly suspected but not confirmed. Antibiotic
therapy was given on the basis of evidence ofH. pylori infection. Successful eradication ofH. pylori resulted in remarkable improvement of endoscopic and histological findings. Follow-up studies were carried out 8 months after
eradication, with no evidence of relapse. The eradication ofH. pylori appears to be an effective alternative therapy for B-cell lymphoproliferative disease, although longer follow-up and further
studies are needed before this treatment can be establisted. 相似文献
Although Helicobacter pylori have been identified in the liver, the role of Helicobacter sp. in human liver diseases remains unclear. This study explored whether H. pylori were internalized and could persist in hepatocytes. The majority of an inoculum of H. pylori (1 x 10(7) colony forming units) adhered to hepatocytes. Using the gentamicin invasion assay we found that approximately 2% were internalized and persisted following passage for more than 2 months. Electron microscopy confirmed the presence of intracellular Helicobacter. The number of adherent or internalized H. pylori was significantly greater with hepatocytes than with gastric epithelial cells (P < 0.05) and was also dependent on cag pathogenicity island (PAI), VacA, OipA, or BabA status. Transmission electron microscopy was used to confirm adherence and invasion of H. pylori into hepatocytes. Internalization of H. pylori was inhibited by antibodies to beta1-integrin receptors, genistein, and cytochalasin D (P < 0.05) consistent with beta1-integrin acting as a surface receptor with additional requirements for tyrosine kinase phosphorylation and actin polymerization. In summary, H. pylori both adhered to and invaded into hepatocytes in vitro, depending on the virulent factors, and persisted within hepatocytes during subcultures. beta1-integrin is likely a receptor involved in internalization of H. pylori into hepatocytes. 相似文献
Poly(ethylene glycol) (PEG) is partially furanylated with different feed ratios of furfuryl isocyanate and used as the macro initiator of ring‐opening polymerization of l ‐ and d ‐lactides to synthesize copolymer mixtures of furan‐terminated AB diblock and ABA triblock copolymers (poly(oxyethylene)–poly(l ‐lactide)/poly(l ‐lactide)–poly(oxyethylene)–poly(l ‐lactide) and poly(oxyethylene–poly(d ‐lactide)/poly(d ‐lactide)–poly(oxyethylene)–poly‐(d ‐lactide)) having different diblock/triblock ratios. The mixed micelle solutions of these enantiomeric copolymer mixtures undergo sol‐to‐gel or gel‐to‐sol transition depending on the diblock/triblock ratio of the copolymer mixtures. The rheological properties of the mixed micelle solutions could also be controlled by changing the diblock/triblock ratios or the initial furanylation ratio of PEG.
Ethambutol-induced optic neuropathy (EON) is a well-known complication, although low-dose ethambutol seldom causes EON. An 85-year-old man with non-tuberculous mycobacterial lung disease was taking antibiotics, including low-dose ethambutol. On day 85 of treatment, the diagnosis of EON was made. Despite prior discontinuation, his best corrected visual acuity drastically deteriorated from 20/17 (right eye) and 20/20 (left eye) to 20/330 (right eye) and 20/1,000 (left eye) within 3 weeks, and this symptom did not resolve. To our knowledge, there have been no reported cases with drastically progressing and irreversible EON even after the withdrawal of low-dose and short-term ethambutol. 相似文献
BackgroundPolymer-free biolimus A9-coated coronary stent (DCS) has novel features which lead to the expectation of better arterial healing. However, comparisons of intravascular status between DCS and drug-eluting stents (DES), and robust real-word clinical assessments of DCS have been lacking to date.MethodsFrom September 2017 to September 2018, we evaluated the intra-vascular status of 74 DCS implanted in 55 lesions from 43 patients using coronary angioscopy (CAS) approximately one year after implantation from a cohort of 219 lesions in 158 patients. We set 239 second-generation durable-polymer DES (DP-DES) implanted in 211 lesions from 180 patients from a cohort of 2652 lesions in 1914 patients as the control. Angioscopic images were analyzed to determine (1) the dominant degree of neointimal coverage (NIC) over the stent; (2) the heterogeneity of NIC; (3) yellow color grade of the stented segment; and (4) the presence of intra-stent thrombus. The primary outcome was the incidence of thrombus and secondary outcomes were the other CAS findings, and the 1-year clinical outcomes which included target lesion revascularization (TLR) and major adverse cardiac events (MACE). To minimize inter-group differences in baseline characteristics, propensity score matching was performed for clinical outcomes.ResultsIncidence of thrombus adhesion was similar in DCS and DP-DES groups (28.4% versus 22.6%, p = 0.31). However, the dominant NIC grade was significantly higher in DCS (p < 0.001), while NIC was more heterogeneous in DCS than in DP-DES (p = 0.001). Maximum yellow color grade was similar (p = 0.22). After propensity score matching, 202 lesion pairs from 146 patient pairs were retained for analysis. The cumulative incidence of TLR (4.6% versus 3.8%, p = 0.38) and MACE (11.6% versus 11.7%, p = 0.84) was similar for DCS and DP-DES.ConclusionsDCS showed thrombus adhesion and clinical outcomes at 1 year similar to DP-DES. DCS can thus be used with similar safety and efficacy as DP-DES. 相似文献
