This article is aimed to retrospect the clinicopathological data of 2 cases of gastric MANENCs. MANEC is a rare biphasic tumor type that is coexistence of dual neuroendocrine and adenocarcinoma differentiation with each composing exceeding 30% volume. Gastric MANEC have just been reported anecdotally in the literature due to their rarity and heterogeneity. According to our study, these neoplasms have 3 different metastasis patterns: only adenocarcinomatous or neuroendocrine carcinoma and both of the 2 components. We first focus on the correlation of metastasis characteristics with prognosis in gastric MANEC, which may be potential implications for the choice of chemotherapy. ⋯ The assessment of metastatic sites should be a routine pathological practice, which is crucial for clinical decision-making and the selection of management.

Sarcoidosis is associated with cell-mediated immunodeficiency and treatment of symptomatic sarcoidosis usually includes systemic immunosuppressants. Data relative to incidence, prognosis factors, and outcome of infections are scarce. Retrospective cohort study of 585 patients with biopsy proven sarcoidosis in a tertiary referral specialist clinic, with a nested case-control analysis. ⋯ Two patients died within the 6 months following infection, due to progressive multifocal leucoencephalopathy (n = 1), and of peritonitis (n = 1). Severe infections are observed in 5.1% of our patients with sarcoidosis after a median follow-up of 8 years. Risk factors for severe infections included neurological or cardiac involvement of sarcoidosis, the use of immunosuppressive agents and mainly cyclophosphamide.

The mechanisms linking short stature with an increase in cardiovascular and cerebrovascular disease risk remain elusive. This study tested the hypothesis that significant associations are present between height and blood pressure in a representative sample of the US adult population. Participants were 12,988 men and women from a multiethnic sample (age ≥ 18 years) evaluated in the 1999 to 2006 National Health and Nutrition Examination Survey who were not taking antihypertensive medications and who had complete height, weight, % body fat, and systolic and diastolic arterial blood pressure (SBP and DBP) measurements; mean arterial blood pressure and pulse pressure (MBP and PP) were calculated. ⋯ Socioeconomic status, activity level, and smoking history did not consistently contribute to blood pressure prediction models. Height-associated blood pressure effects were present in US adults who appeared in the 4th decade and increased in magnitude with greater age thereafter. These observations, in the largest and most diverse population sample evaluated to date, provide support for postulated mechanisms linking adult stature with cardiovascular and cerebrovascular disease risk.

Situs inversus totalis is a rare anomaly disease in which the organs in the chest and abdomen are positioned in a mirror image reversal of normal positions. Although this has been confirmed to be associated with spinal abnormalities, reports about situs inversus totalis with congenital scoliosis remain limited. ⋯ Growing rods technique could be a safe and effective alternative for the treatment of scoliosis associated with situs inversus totalis. In the correction of left-sided lumbar curve of this kind of patients, the risks of aorta impingements should not be neglected when placing pedicle screws on the concave sides.

Ectopic thyroid carcinoma within a thyroglossal duct cyst (TGDCCa) is an extremely rare entity. Thus, there is no unified appropriate therapeutic strategy, and individual approaches are controversial. ⋯ Therapeutic management of TGDCCa is of interdisciplinary debate due to relative infrequence of the disease and consequently lack of unified therapeutic guidelines. We suggest a personalized therapeutic approach adjusted to individual risk stratification. In young patients with small tumor size and with confirmation of TGDCCa representing the primary tumor, Sistrunk procedure alone may reflect adequate treatment. In all other cases, total thyroidectomy and radioiodine ablation should be evaluated. Overall TGDCCa have an excellent prognosis with a 5-year survival rate of more than 90%.
