Objective As the calreticulin (CALR) mutation frequency is significantly associated with essential thrombocythemia (ET) and primary myelofibrosis (PMF), this mutation may be an important biomarker in patients with ET and PMF. Methods We performed a literature search until April 2015 and obtained 21 relevant studies. The outcome was pooled as the effect size by using the Stata software program. ⋯ Moreover, the mutation ratio in Asian patients with PMF was lower (21%) than that in European-American patients (23%). A slight trend toward fibrotic transformation was found in ET with CALR mutations, whereas leukemic transformation was not significant in patients with ET or PMF with CALR mutations. Conclusion CALR mutations significantly influence the incident of ET as demonstrated by the meta-analysis.

Case Reports
Advanced Lymphocyte-rich Classical Hodgkin Lymphoma Complicated with Fatal Hemophagocytic Syndrome.
Lymphocyte-rich classical Hodgkin lymphoma (LRCHL) is a rare subtype of Hodgkin lymphoma with a favorable prognosis, and an aggressive clinical course of LRCHL is uncommon. A 55-year-old man suffering from swelling in the left neck was diagnosed with LRCHL with extranodal lesions in the lung and bone marrow. ⋯ He received two subsequent courses of intensive chemotherapy containing high-dose steroids, cyclophosphamide, and etoposide. Nevertheless, this therapy was only temporarily effective, and he died of due to an aggressive disease progression accompanied by uncontrollable HPS and severe coagulopathy.

Objective The adverse effects of selective sodium-glucose co-transporter 2 (SGLT2) inhibitors generally appear within about two or three months after treatment initiation in Japan. Therefore, we investigated the impact of tofogliflozin, a class of SGLT2 inhibitors, on glycemic control and body composition during this period in Japanese patients with type 2 diabetes mellitus. Methods This single-arm open-label study enrolled 20 patients. ⋯ The degree of improvement in HbA1c was correlated with the baseline fat mass and BMI. Conclusion An eight-week administration of tofogliflozin improved glycemic control and reduced the body weight and free fat mass in type 2 diabetic patients without affecting the fat mass. In this period, the hematocrit level and renal function should be monitored to guard against hemoconcentration and renal impairment, respectively.

We mainly refer to the acute setting of meningococcemia. Meningococcemia is an infection caused by Neisseria meningitidis, which has 13 clinically significant serogroups that are distinguishable by the structure of their capsular polysaccharides. N. meningitidis, also called meningococcus, is a Gram-negative, aerobic, diplococcus bacterium. ⋯ Meningococcal infection is a medical emergency that requires antibiotic therapy and intensive supportive care. Management of the systemic circulation, respiration, and intracranial pressure is vital for improving the prognosis, which has dramatically improved since the wide availability of antibiotics. This review of the literature provides an overview of current concepts on meningococcemia due to N. meningitidis infection.

An 82-year-old woman with autoimmune hepatitis had been treated with 5 mg prednisolone (PSL) orally to maintain normal transaminase levels. The subsequent transaminase levels were elevated and remained unchanged despite increasing the dose of PSL to 20 mg and introducing ursodeoxycholic acid (UDCA) at a dose of 900 mg. ⋯ Oral administration of PSL was discontinued eight weeks after the co-administration of Saireito. The patient had a significant response to this treatment.
