Current histopathological diagnosis methods cannot distinguish the two types of thyroid carcinoma: clinically significant carcinomas with a potential risk of recurrence, metastasis, and cancer death, and clinically insignificant carcinomas with a slow growth rate. Both thyroid tumors are diagnosed as "carcinoma" in current pathology practice. The clinician usually recommends surgery to the patient and the patient often accepts it because of cancer terminology. The treatment for these clinically insignificant carcinomas does not benefit the patient and negatively impacts society. The author proposed risk stratification of thyroid tumors using the growth rate (Ki-67 labeling index), which accurately differentiates four prognostically relevant risk groups based on the Ki-67 labeling index, ≥30%, ≥10 and30%,5 and10%, and ≤5%. Indolent thyroid tumors with an excellent prognosis have the following four features: young age, early-stage (T1-2 M0), curatively treated, and low proliferation index (Ki-67 labeling index of ≤5%), and are unlikely to recur, metastasize, or cause cancer death. Accurate identification of these indolent tumors helps clinicians select more conservative treatments to avoid unnecessary aggressive (total thyroidectomy followed by radio-active iodine) treatments. Clinicians can alleviate the fears of patients by confirming these four features, including the low proliferation rate, in a pathology report immediately after surgery when patients are most concerned.

The purpose of this cross-sectional study was to investigate the effect of chronic hemodialysis on toe pinch force (TPF). A total of 37 chronic hemodialysis patients without type 2 diabetes mellitus (T2DM) (age: 69.4 ± 11.8 years, duration of hemodialysis: 3.5 ± 3.4 years) were enrolled in this study. The TPF in chronic hemodialysis patients without T2DM was compared with that in 34 apparently healthy participants and 37 chronic hemodialysis patients with T2DM. There was no significant difference in clinical profiles between healthy participants and chronic hemodialysis patients with and without T2DM. The TPF in chronic hemodialysis patients without T2DM was lower compared with that in healthy participants (2.70 ± 1.05 kg vs. 3.34 ± 0.99 kg, p = 0.025). In addition, the TPF in patients with T2DM was even lower compared with that in patients without T2DM (2.12 ± 1.01 kg vs. 2.70 ± 1.05 kg, p = 0.042). This study showed a dramatic reduction in TPF in chronic hemodialysis patients, especially in those with T2DM.

PURPOSE: This exploratory study compared the lower-limb muscle mass (thigh muscle mass [TMM] and lower-leg muscle mass [LLMM]) in type 2 diabetic patients with and without diabetic polyneuropathy (DPN). METHODS: A total of 130 patients with type 2 diabetes, hospitalized for glycemic control, were enrolled in this cross-sectional study. TMM and LLMM were measured using the bioelectrical impedance method. The muscle mass value was normalized by the bodyweight, and the total muscle mass was calculated by combining the muscle mass on the left and right (%TMM and %LLMM). DPN was evaluated according to the Japanese criteria. Anthropometric parameters, blood pressure, laboratory data, exercise habits, medication, related index of diabetes, and diabetic complications were analyzed. RESULTS: Sixty patients, comprising of 32 males (47.8%) and 28 females (44.4%) with type 2 diabetes (46.2%), had DPN. The %TTM and %LLMM were significantly lower in type 2 diabetic patients with DPN than in those without DPN. Multiple regression analysis identified DPN, age, and hemoglobin A1c (HbA1c) as the determinants of %TMM, and DPN and HbA1c were identified as the determinants of %LLMM in type 2 diabetic patients. DISCUSSION: The %TMM and %LLMM were significantly decreased in type 2 diabetic patients with DPN. DPN was found to be the strongest determinant of %TMM and %LLMM. Preventing and improving DPN, through active physical therapy, may increase the muscle mass of the lower limbs.

The purpose of this cross-sectional study was to investigate the toe pinch force (TPF) of type 2 diabetic patients with diabetic nephropathy by disease stage, and to clarify the factors affecting the TPF. Seventy-four men with diabetic nephropathy (age: 62.7 ± 8.9 years, duration of diabetes: 14.2 ± 8.6 years) were enrolled. According to the staging of diabetic nephropathy, TPF and knee extension force (KEF) were compared among three groups: normoalbuminuria, microalbuminuria, and overt nephropathy. In addition, we investigated factors influencing TPF and KEF by performing multiple regression analysis. Normoalbuminuria group, microalbuminuria group, and overt nephropathy group included 26, 25, and 23 patients, respectively. The TPF of the overt nephropathy group (3.15 ± 0.75 kg) was significantly lower than that of the normoalbuminuria (4.2 ± 0.7 kg, p

We compared the toe pinch force in men with and without type 2 diabetes mellitus (T2DM). Sixty-eight male T2DM patients and 35 apparently healthy men matched for age, sex, and body mass index (BMI) were enrolled in this cross-sectional study. We compared the toe pinch force between the subjects with and without T2DM, and we evaluated the effect of diabetic polyneuropathy on toe pinch force in the patients. The toe pinch force of the T2DM patients was significantly lower than that of the subjects without diabetes (3.12±1.22 kg vs. 4.40±1.19 kg, p

The purpose of this pilot study was to investigate the effect of short-term toe resistance training on toe pinch force and toe muscle quality in patients with type 2 diabetes mellitus. A total of 12 patients with type 2 diabetes mellitus who were hospitalized to improve glycemic control (8 men and 4 women, duration of diabetes 12.2 ± 9.5 years) were enrolled in this pilot study. Exercise therapy was performed with conventional aerobic exercise and four newly developed toe resistance training exercises for 2 weeks. Changes in anthropometric parameters, blood pressure (BP), heart rate, and muscle parameters, i.e. muscle mass, toe pinch force and toe muscle quality were evaluated after the exercise program. There were no significant differences of body weight, body mass index, BP, heart rate, and upper/lower muscle mass after exercise performance. However, toe pinch force was significantly increased (pre: 2.92 ± 1.19 kg, post: 3.65 ± 1.58 kg, p = 0.007). Toe muscle quality (toe pinch force/lower leg muscle mass) were also significantly increased (pre: 2.15 ± 0.86 kg/kg, post: 2.72 ± 1.26 kg/kg, p = 0.009). Two weeks of toe resistance training significantly increased toe pinch force and toe muscle quality in patients with type 2 diabetes mellitus. Toe resistance training is might be essential for treating patients with diabetes mellitus in clinical practice.

The aim of this study was to explore the relations between toe pinch force and other muscle strength parameters in male patients with type 2 diabetes mellitus. A total of 40 men with type 2 diabetes (age: 53.4 ± 13.1 years, duration of diabetes: 8.5 ± 8.1 years) who needed exercise training were enrolled in this cross-sectional study. We evaluated the clinical parameters and 4 muscle strength parameters, which were toe pinch force, handgrip strength, isometric knee extension force, and isometric ankle dorsiflexion force. The HbA1c, toe pinch force, handgrip strength, isometric knee extension force, and isometric ankle dorsiflexion force were 10.1 ± 2.4 %, 3.2 ± 1.2 kg, 37.3 ± 7.0 kg, 39.6 ± 11.4 kgf, and 17.0 ± 6.3 kgf, respectively. Toe pinch force was significantly correlated with handgrip strength (r = 0.365, p = 0.0206), isometric knee extension force (r = 0.668, p

Subcutaneous panniculitis-like T-cell lymphoma (SPTCL) is a primary T-cell lymphoma that preferentially involves the subcutaneous tissue. SPTCL is restricted to primary cutaneous T-cell lymphoma expressing the αβ T-cell receptor (TCR) phenotype [1]. Recent studies have demonstrated that lymphoma cells express certain chemokine receptors, and that they are associated with the pathology and clinical behaviour of cutaneous lymphoma [2]. Herein, we report a case of SPTCL and present an immunohistochemical [...]

Lipodystrophyis a rare disorder characterised by selective loss of subcutaneous and visceral fat. It is commonly associated with hypertriglyceridaemia, hepatomegaly, and disordered glucose metabolism [1]. The precise pathogenesis is largely unknown, but autoimmunity is a possible cause of lipodystrophy [1]. Although autologous fat transfer to the atrophic site is a therapeutic option, there is no established treatment for idiopathic lipodystrophy. Herein, we report a case of lipodystrophy coexistent [...]
