Serum soluble CD163 levels in patients with influenza-associated encephalopathy

Background: Influenza-associated encephalopathy (IE) is a serious complication during influenza viral infection. Common clinical symptoms of IE include seizures and progressive coma with high-grade fever. We previously reported that hypercytokinemia and monocyte/macrophage activation may play an important role in the pathogenesis of IE. CD163 is a scavenger receptor for hemoglobin–haptoglobin complexes and is expressed by monocytes/macrophages. Proteolytic cleavage of monocyte-bound CD163 by matrix metalloproteinases releases soluble CD163 (sCD163). However, there have been no reports regarding serum sCD163 levels in IE patients. Methods: We measured serum levels of sCD163 as a marker of monocyte/macrophage activation in IE patients with poor outcomes, those without neurological sequelae, influenza patients without IE, and control subjects. Results: Serum sCD163 levels were significantly higher in IE patients with poor outcomes than in those without neurological sequelae. In particular, sCD163 levels in cases of death were significantly higher than those in other cases. Conclusions: Our results suggest that monocyte/macrophage activation is related to the pathogenesis of severe IE.     

A study of psycho-pathology and treatment of children with phagophobia

Phagophobia is a disorder characterized by a conditioned excessive fear of eating and is initiated by an event such as vomiting or choking. During childhood, vomiting often occurs as a result of infection or overeating, and painful experiences bring about maladaptive eating behavior like food refusal. There have been few reports of phagophobia, and patients have sometimes been misdiagnosed with anorexia nervosa (AN). The objective of this study was to elucidate the psycho-pathology and current treatment of patients with phagophobia by analyzing case studies. We describe 6 cases with phagophobia. Patients with strong obsessions were refractory to treatment, indicating that evaluation of premorbid personality is crucial to the prognosis. It is important to classify this disorder according to psycho-pathology into "post-traumatic type" and "gain-from-illness type" to make a treatment plan. A solution focused approach is also effective for patients and their family. Paying close attention to these conditions and to the diagnostic concept referred as "hagophobia" is useful in achieving these aims.     

Intra-procedural anticoagulation and post-procedural hemoglobin fall in atrial fibrillation ablation with minimally interrupted direct oral anticoagulants: comparisons across 4 drugs

Successful esophageal bypass operation for esophagobronchial fistula following chemotherapy for malignant lymphoma: a case report

A 72-year-old man with non-Hodgkin’s lymphoma at the tracheal bifurcation node received combination chemotherapy and subsequently developed a fistula in spite of remission of the lymphoma. Conservative therapy did not heal the fistula formation, and we chose bypass surgery using a gastric tube without thoracotomy. Ten months postoperatively, there is no evidence of lymphoma relapse and the patient lives a normal life. We consider this procedure as an available treatment for esophagobronchial fistula in case of failure to cure fistula communication by conservative therapy.     

The effect of medroxyprogesterone acetate on gonadotropin secretion in girls with precocious puberty.

Plasma luteinizing hormone (LH) and follicle stimulating hormone (FSH) as detected by radioimmunoassay have been found to be present in prepubertal children and show a gradual rise until the onset of puberty. Children with idiopathic true precocious puberty have plasma gonadotropin levels which are appropriate for their advanced degree of sexual development. A potent progestational agent, 6-methyl-17-hydroxyprogesterone acetate or medroxyprogesterone has been used in the treatment of precocious puberty and will suppress its physical manifestations. In this study the effect of medroxyprogesterone on gonadotropin levels was investigated in seven girls with true precocious puberty. Plasma LH values were found to be significant lower in patients receiving this agent than in a group of normal prepubertal girls. FSH values did not differ from the control group. One patient was evaluated prior to treatment and showed decreasing levels of LH after therapy was begun. These data suggest that medroxyprogesterone may act on the pituitary-hypothalamic axis to suppress the pubertal levels of LH.     

Molecular Detection of Diphyllobothrium nihonkaiense in Humans,China

The cause of diphyllobothriosis in 5 persons in Harbin and Shanghai, China, during 2008–2011, initially attributed to the tapeworm Diphyllobothrium latum, was confirmed as D. nihonkaiense by using molecular analysis of expelled proglottids. The use of morphologic characteristics alone to identify this organism was inadequate and led to misidentification of the species.
