Efficacy of Zinc Acetate in the Treatment of Zinc Deficiency in Elderly Inpatients and Effect of Total Dose on Its Replacement Therapy.

We aimed to determine the efficacy of zinc acetate hydrate (ZAH) treatment for hypozincemia in elderly inpatients and to identify the factors affecting its therapeutic effect. We enrolled 79 patients with a mean age of 82 years. The mean serum zinc level before ZAH administration was 53.

[Retrospective Analysis of Factors Decreasing the Efficacy of Tazobactam/Piperacillin for Pneumonia in Elderly Patients].

　Tazobactam/piperacillin (TAZ/PIPC) is an antimicrobial drug agent with a broad spectrum of antibacterial activity and is recommended as first-line therapy for hospital-acquired pneumonia, nursing- and healthcare-associated pneumonia, and other severe pneumonias. Nevertheless, in clinical settings, TAZ/PIPC is not fully effective in the treatment of pneumonia in the elderly. In the present study, we retrospectively investigated the efficacy of TAZ/PIPC for pneumonia in elderly patients and identified factors that reduced its efficacy.

[Factors contributing to increases in serum creatinine following treatment with a sulfamethoxazole-trimethoprim combination product: retrospective analysis of Japanese patients with normal renal function].

  Japanese patients with normal renal function were retrospectively analyzed to characterize increases in serum creatinine (SCr) observed following the use of a sulfamethoxazole-trimethoprim (SMX-TMP) combination product and identify factors affecting these increases. In the patients studied (n=49), an individual comparison was conducted for the three factors of age group [≤74 years (n=21) vs. ≥75 years (n=28)], sex [male (n=24) vs.

[Sensory nerve anesthesia with 4% liposomal lidocaine cream in healthy subjects by use of the neuroselective current perception threshold].

Background: ELA-Max, an external liposomal preparation of lidocaine (4%) available without prescription in United States, has a recommended application time of 15 to 45 min without occlusive dressing, and the side effect has been reported to be rare. To investigate external anesthetic preparations to reduce neuropathic pain, we evaluated sensory nerve anesthesia by ELA-Max in comparison with placebo and other lidocaine topical preparations by double blind method.

Methods: We measured the neuroselective current perception threshold (N-CPT) 30 min after the application of ELA-Max on 30 healthy Japanese volunteers.
