An Elderly Patient with Pulmonary Cryptococcosis with Mediastinal Lymphadenopathy Who Was Successfully Treated with Amphotericin B and Flucytosine.

Pulmonary cryptococcosis develops not only in immunocompromised patients but also in immunocompetent patients. However, lymph node involvement is relatively rare in immunocompetent patients. We herein report the case of an 80-year-old man who was not in an apparent immunocompromised state but was diagnosed with pulmonary cryptococcosis with mediastinal lymphadenopathy. The patient was resistant to fluconazole and voriconazole monotherapy; thus, his lung lesions significantly worsened. He eventually responded well to a combination therapy of amphotericin B and flucytosine, which was administered according to the treatment strategy for disseminated diseases.

Prolonged Tachycardia with Higher Heart Rate Is Associated with Higher ICU and In-hospital Mortality.

Tachycardia is common in intensive care units (ICUs). It is unknown whether tachycardia or prolonged tachycardia affects patient outcomes. We investigated the association between tachycardia and mortality in critically ill patients. This retrospective cohort study's primary outcome was patient mortality in the ICU and the hospital. We stratified the patients (n=476) by heart rate (HR) as LowHR, MediumHR, and HighHR groups. We also stratified them by their durations of HR >100 (prolonged HR; tachycardia): MildT, ModerateT, and SevereT groups. We determined the six groups' mortality. The ICU mortality rates of the LowHR, MediumHR, and HighHR groups were 1.0%, 1.5%, and 7.9%, respectively; significantly higher in the HighHR vs. LowHR group. The in-hospital mortality rates of these groups were 1%, 4.5%, and 14.6%, respectively; significantly higher in the HighHR vs. LowHR group. The ICU mortality rates of the MildT, ModerateT, and SevereT groups were 0.9%, 5.6%, and 57.1%, respectively. The mortality of the HRT=0 (i.e., all HR ≤ 100) patients was 0%. The in-hospital mortality rates of the MildT, ModerateT, and SevereT groups were 1.8%, 16.7%, and 85.7%, respectively; that of the HRT=0 patients was 0.5%. Both higher HR and prolonged tachycardia were associated with poor outcomes.

Long-term practice induced plasticity in the primary motor cortex innervating the ankle flexor in football juggling experts.

The aim of this study was to investigate the plasticity of M1 innervating the tibialis anterior muscle (TA) induced by the long-term practice of football juggling using a transcranial magnetic stimulation (TMS) technique. Ten football juggling experts and ten novices participated in this study. Motor evoked potentials (MEP) and the H-reflex were recorded from the right TA during isometric dorsiflexion at 10% of maximum voluntary contraction. The MEP input-output curve of the experts was steeper than that of the novices, and reduced short-interval intracortical inhibition and long-interval intracortical inhibition were observed in the experts. In contrast, the ratio of Hmax to Mmax did not differ between the groups. Our results show that football juggling experts displayed enhanced excitability in the M1 innervating the TA, which was induced by the long-term practice of the ankle movements required to perform football juggling well.
