A 59-year-old woman was admitted to our hospital for an evaluation of a 10-day history of progressive pain and hypoesthesia of the right lower back associated with fever and constipation. Sarcoidosis was confirmed on mediastinal lymph node and skin biopsies. ⋯ The intraepidermal nerve fiber density assessed on a skin biopsy was significantly reduced, suggesting small-fiber neuropathy (SFN). The patient was finally diagnosed with sarcoidosis-induced SFN, and her neurological symptoms were effectively relieved with high-dose steroid therapy.

Multicenter Study
The Differences in the Epidemiology and Predictors of Death between Candidemia Acquired in Intensive Care Units and Other Hospital Settings.
The burden of candidemia is shifting from intensive care units (ICU) to non-ICU settings. This study aimed to define the differences in epidemiology and predictors of death between ICU-acquired candidemia (ICUAC) and non-ICUAC. ⋯ The Candida species and antifungal resistance profiles in patients with ICUAC were similar to non-ICUAC patients, but led to worse outcomes. The protective and risk factors for death may therefore be relevant for the clinical management of patients with candidemia in ICU and non-ICU settings.

High-flow nasal cannula (HFNC) therapy is an oxygen delivery system. However, evidence regarding the clinical applications of HFNC is still emerging. We herein evaluated the clinical predictors of HFNC therapy success for adult patients with acute hypoxemic respiratory failure. ⋯ HFNC therapy showed a good compliance and the improvement of the physiologic parameters in an adult population. The failure to improve oxygenation within 24 hours was a useful predictor of intubation. Among the failure group, the vasopressor use and failed oxygenation improvement were associated with ICU mortality.

The impact of the clustering of metabolic factors on chronic kidney disease (CKD) in non-obese individuals remains unclear. ⋯ Non-obese subjects with ≥3 metabolic factors, who are missed based on the essential criterion of obesity for metabolic syndrome, may have an equal or slightly higher risk of renal dysfunction than obese subjects with ≥3 metabolic factors.

Case Reports
A Rare Case of Variant Hemoglobin (Hb Yahata) Suspected Based on Inconsistent Plasma Glucose and HbA1c Levels.
A 52-year-old man presented for an evaluation of worsening glycemic control secondary to glucocorticoid administration. The glycated hemoglobin (HbA1c) level was 8%, and oral glucose tolerance testing revealed impaired tolerance, whereas the plasma glucose and glycoalbumin levels were normal. The results of high-performance liquid chromatography (HPLC) for HbA1c, isoelectrofocusing of the hemolysate and precise HPLC measurements of the HbA1c level supported the presence of an Hb variant, and DNA sequencing of the β-globin gene revealed Hb Yahata [β112 TGT (Cys)→TAT (Tyr)] (heterozygote). In this case, the discrepancy between the plasma glucose and HbA1c levels raised suspicion of this rare Hb variant.
