Various laboratory markers of inflammation are utilized in general practice, but their clinical diagnostic significance is often ambiguous. In the present study, we determined the clinical significance of the examination of serum levels of procalcitonin (PCT) by comparing the PCT levels with the levels of other inflammatory markers, based on a retrospective review of 332 PCT-positive patients, including cases of bacterial infection (20.5%), non-specific inflammation (20.8%), neoplasm (9.9%), con...

Objective null Urinary free cortisol (UFC) is a reliable marker to avoid cortisol fluctuation and the effects of binding proteins. However, UFC levels are affected by fluid intake and urine volume, and the normal levels range widely. null Methods null To discover the utility of the ratio of urinary cortisol to aldosterone excretions, 246 patients in whom daily excretions of UFC and aldosterone (UAC) were measured were retrospectively analyzed. null Results null The UFC/UAC ratio showed significa...

A 75-year-old man with well-controlled type 2 diabetes was referred to our department because of urinary obstruction. He developed retroperitoneal fibrosis 1 year prior to the referral and underwent a ureteral stent insertion at that time. Around the same period, double vision and eyelid ptosis of the right eye coincidentally appeared (figure 1A). We performed MRI of the orbit; it revealed bilateral lacrimal enlargement, especially at the right side (figure 1B, C …

We report a patient with adrenal incidentaloma due to synchronous and isolated metastasis from lung cancer, which is a relatively rare condition. Close checkups for incidentaloma in oncologic patients are mandatory, leading to successful operation.

To determine the clinical characteristics of low androgen status in adult males with diabetes, we retrospectively analyzed the medical records of patients with type 2 diabetes mellitus in whom serum free testosterone (FT) levels were examined for 1 year. Among the 46 patients (56 ± 1.5 years old), decreases in serum FT levels to < 8.5 pg/ml (indicating the occurrence of late-onset hypogonadism [LOH]) were detected in 18 (39%). The per-centages of patients with low FT levels were high in the ≥ 50...

Alkaline phosphatase (ALP) is an enzyme that is expressed in a variety of tissues. Among the isoforms of ALP, bone-specific alkaline phosphatase (BAP) is used as a marker for evaluating bone metabolism. We investigated the clinical usefulness of the ratio of serum BAP to total ALP for the diagnosis of various disorders in general practice. We retrospectively analyzed the cases of 107 Japanese patients whose serum BAP levels were exam-ined, focusing on clinical characteristics. We observed that t...
