Review Case Reports
Mixed-type multicentric Castleman's disease developing during a 17-year follow-up of sarcoidosis.
Multicentric Castleman's Disease (MCD) is a systemic disease characterized by generalized lymphadenopathy and the proliferation of plasma cells. The development of MCD in a patient with preexisting sarcoidosis has not been previously reported. ⋯ The patient's serum interleukin-6 (IL-6) levels were only slightly elevated; however, the IL-6 levels in the fluid of both pleural effusion and ascites were markedly elevated. The administration of steroid-pulse therapy and prednisolone was ineffective in treating the MCD, although treatment with tocilizumab proved highly effective.

Randomized Controlled Trial
Dexmedetomidine versus midazolam for the sedation of patients with non-invasive ventilation failure.
To compare the efficacy and safety of sedation with dexmedetomidine vs. midazolam for patients with acute cardiogenic pulmonary edema and hypoxemia during the treatment of non-invasive ventilation (NIV). ⋯ Dexmedetomidine led to a more desired level of awaking sedation, shortened the duration of mechanical ventilation and the length of the ICU stay, and further reduced the prevalence of nosocomial infection for NIV sedation in patients with acute cardiogenic pulmonary edema. It appears to provide several advantages and safe control compared with the γ-amino butyric acid (GABA) agonist midazolam.

Randomized Controlled Trial
Effect of rosuvastatin on ROCK activity, endothelial function, and inflammation in Asian patients with atherosclerosis.
HMG-CoA reductase inhibitors (statins) inhibit cholesterol biosynthesis, and also decrease the formation of isoprenoid intermediates required for the activation of Rho kinase (ROCK) pathway. ROCK pathway plays pivotal roles in cardiovascular diseases including arteriosclerosis. It has been implicated that inhibition of ROCK can reverse vascular dysfunction in humans with atherosclerosis. However, it is not clear whether statins, at doses used to lower cholesterol levels, inhibit ROCK activity in humans with atherosclerosis. ⋯ These results demonstrate that high dose rosuvastatin exerts greater effects on LDL-C, ROCK activity, and CRP than low dose rosuvastatin. These findings provide clinical evidence that statins are effective in improving endothelium dysfunction by a cholesterol-independent mechanism in patients with atherosclerosis.

Randomized Controlled Trial
Prevention of contrast-induced nephropathy with ascorbic acid.
Some studies have shown that antioxidant ascorbic acid has renal protective effects, but the beneficial effects of contrast-induced nephropathy prevention remain to be clearly shown. Therefore, we aimed to determine whether ascorbic acid pretreatment reduces the risk of contrast-induced nephropathy in a high-risk population of patients with renal insufficiency undergoing coronary angiography. ⋯ Ascorbic acid pretreatment for short-term at high dose do not prevent renal function deterioration after administration of contrast medium in patients with baseline renal insufficiency undergoing coronary angiography.

A 28-year-old woman was referred to our hospital for treatment of tuberculous lymphadenitis, after presenting with fever, left cervical lymphadenopathy, and a positive interferon-gamma release assay (QuantiFERON®-TB Gold In-Tube; QFT) result. Surprisingly, biopsy specimens of the cervical lymph nodes showed necrotic lesions with prominent nuclear debris and a proliferation of histiocytes, consistent with Kikuchi-Fujimoto disease (KFD). ⋯ KFD may be misdiagnosed as tuberculous lymphadenitis, and antibiotics unnecessarily prescribed. Careful attention should therefore be paid when diagnosing cervical lymphadenopathy.
