Resistance to thyroid hormone (RTH) is a rare autosomal dominant inherited disorder characterized by end-organ reduced sensitivity to thyroid hormone. This syndrome is caused by mutations of the thyroid hormone receptor (TR) β gene, and its clinical presentation is quite variable. Goiter is reported to be the most common finding. A close association of TRβ mutations with human cancers has become apparent, but the role of TRβ mutants in the carcinogenesis is still undefined. Moreover, higher TSH levels, described in RTH syndrome, are correlated with increased risk of thyroid malignancy, whereas TSH receptor stimulation is likely to be involved in tumor progression. We report here an illustrative case of a 29 year-old patient with RTH caused by a mutation in exon 9 (A317T) of TRβ gene, who presented multicentric papillary thyroid cancer. We review the literature on this uncommon feature, and discuss the potential role of this mutation on human tumorigenesis, as well as the challenges in patient follow-up.

AbstractTakotsubo syndrome (TTS) is an acute heart failure syndrome with significant rates of in and out-of-hospital mayor cardiac adverse events (MACE). To evaluate the possible role of neoplastic biomarkers [CA-15.3, CA-19.9 and Carcinoembryonic Antigen (CEA)] as prognostic marker at short- and long-term follow-up in subjects with TTS. Ninety consecutive subjects with TTS were enrolled and followed for a median of 3 years. Circulating levels of CA-15.3, CA-19.9 and CEA were evaluated at admission, after 72 h and at discharge. Incidence of MACE during hospitalization and follow-up were recorded. Forty-three (46%) patients experienced MACE during hospitalization. These patients had increased admission levels of CEA (4.3 ± 6.2 vs. 2.2 ± 1.5 ng/mL, p = 0.03). CEA levels were higher in subjects with in-hospital MACE. At long term follow-up, CEA and CA-19.9 levels were associated with increased risk of death (log rank p < 0.01, HR = 5.3, 95% CI 1.9–14.8, HR = 7.8 95% CI 2.4–25.1, respectively, p < 0.01). At multivariable analysis levels higher than median of CEA, CA-19.9 or both were independent predictors of death at long term (Log-Rank p < 0.01). Having both CEA and CA-19.9 levels above median (> 2 ng/mL, > 8 UI/mL respectively) was associated with an increased risk of mortality of 11.8 (95% CI 2.6–52.5, p = 0.001) at follow up. Increased CEA and CA-19.9 serum levels are associated with higher risk of death at long-term follow up in patients with TTS. CEA serum levels are correlated with in-hospital MACE.

Abstract Background Thoracic aortic diameters have been associated with cardiovascular risk factors and atherosclerosis. However, limited evidence regarding the role of thoracic aortic diameters as risk markers for major cardiovascular outcomes among women and men exist. Purpose To evaluate the independent associations between crude and indexed ascending and descending aortic (AA and DA) diameters with major cardiovascular outcomes among women and men and to provide optimal cutoff values associated with increased cardiovascular risk. Methods and results 2178 women and men ≥55 years from the prospective population-based Rotterdam Study underwent multi-detector CT scan of thorax. Crude diameters of the AA and DA were measured and indexed by height, weight, body surface area (BSA) and body mass index (BMI). Incidence of stroke, coronary heart disease (CHD), heart failure (HF), cardiovascular and all-cause mortality were evaluated during 13 years of follow-up. Weight-, BSA-, or BMI-indexed AA diameters showed significant associations with total or cardiovascular mortality in both sexes and height-indexed values showed association with HF in women. Crude AA diameters were associated with stroke in men and HF in women. For DA, crude and almost all indexed diameters showed significant associations with either stroke, HF, cardiovascular or total mortality in women. Only weight-, BSA- and BMI-indexed values were associated with total mortality in men. For crude DA diameter, the risk for stroke increased significantly at the 75th percentile among men while the risks for HF and cardiovascular mortality increased at the 75th and 85th percentiles respectively in women. Conclusions Our study suggests a role for descending thoracic aortic diameter as a marker for increased cardiovascular risk, in particular for stroke, heart failure and cardiovascular mortality among women. The cut points for increased risk for several of cardiovascular outcomes were below the 95th percentile of the distribution of aortic diameters.

Abstract Historically, intravenous (IV) antibiotics have been the cornerstone of treatment for uncomplicated Staphylococcus aureus bacteremia (SAB). However, IV antibiotics are expensive, increase the rates of hospital readmission, and can be associated with catheter-related complications. As a result, the potential role of oral antibiotics in the treatment of uncomplicated SAB has become a subject of interest. This narrative review article aims to summarize key arguments for and against the use of oral antibiotics to complete treatment of uncomplicated SAB and evaluates the available evidence for specific oral regimens. We conclude that evidence suggests that oral step-down therapy can be an alternative for select patients who meet the criteria for uncomplicated SAB and will comply with medical treatment and outpatient follow-up. Of the currently studied regimens discussed in this article, linezolid has the most support, followed by fluoroquinolone plus rifampin.

Evidence on the role of supper timing in the development of cardiovascular disease (CVD) is limited. In this study, we examined the associations between supper timing and risks of mortality from stroke, coronary heart disease (CHD), and total CVD. A total of 28,625 males and 43,213 females, aged 40 to 79 years, free from CVD and cancers at baseline were involved in this study. Participants were divided into three groups: the early supper group (before 8:00 p.m.), the irregular supper group (time irregular), and the late supper group (after 8:00 p.m.). Cox proportional hazards regression models were used to calculate hazard ratios (HRs) for stroke, CHD, and total CVD according to the supper time groups. During the 19-year follow-up, we identified 4706 deaths from total CVD. Compared with the early supper group, the multivariable HR of hemorrhagic stroke mortality for the irregular supper group was 1.44 (95% confidence interval [CI]: 1.05–1.97). There was no significant association between supper timing and the risk of mortality from other types of stroke, CHD, and CVD. We found that adopting an irregular supper timing compared with having dinner before 8:00 p.m. was associated with an increased risk of hemorrhagic stroke mortality.

With increasing numbers of childhood cancer survivors who were treated with radiation, there is a need to evaluate potential biomarkers that could signal an increased risk of developing thyroid cancer. We aimed to examine the relationships between thyrotropin and thyroglobulin levels and the risk of developing thyroid nodules and cancer in a cohort of radiation-exposed children. 764 subjects who were irradiated in the neck area as children were examined and followed for up to 25 years. All subjects underwent a clinical examination, measurements of thyrotropin, thyroglobulin levels and thyroid imaging. At baseline, 216 subjects had thyroid nodules and 548 did not. Of those with nodules, 176 underwent surgery with 55 confirmed thyroid cancers. During the follow-up, 147 subjects developed thyroid nodules including 22 with thyroid cancer. Thyroglobulin levels were higher in subjects with prevalent thyroid nodules (26.1 ng/mL vs 9.37 ng/mL; P < 0.001) and in those who had an initial normal examination but later developed thyroid nodules (11.2 ng/mL vs 8.87 ng/mL; P = 0.017). There was no relationship between baseline thyrotropin levels and the prevalent presence or absence of thyroid nodules, whether a prevalent neoplasm was benign or malignant, subsequent development of thyroid nodules during follow-up or whether an incident nodule was benign or malignant. In conclusion, in radiation-exposed children, higher thyroglobulin levels indicated an increased risk of developing thyroid nodules but did not differentiate between benign and malignant neoplasms. There was no association between the baseline TSH level and the risk of developing thyroid nodules or cancer.

A phase II study was initiated in March 1987 at the Regina Elena National Cancer Institute of Rome to evaluate the efficacy of alternating intraperitoneal (IP) recombinant alpha-2-interferon (r-alpha 2-IFN) and cisplatin (DDP) as salvage therapy for less than or equal to 5 mm residual-disease (RD) ovarian carcinoma. Fourteen assessable patients entered the study. All had received prior chemotherapy (11 with DDP-based regimens); five patients had macroscopic RD (less than or equal to 5 mm), and nine had microscopic RD (histologically positive random biopsies and/or positive cytology and immunocytochemical tests). The response to IP immunochemotherapy was evaluated by laparotomy. Pathologic complete remissions (PCRs) were achieved in seven patients (50%) who have remained free of disease with a median follow-up of 22+ months (range, 11+ to 30+ months). Six patients achieved a stable disease and one presented disease progression. With the exception of chemical peritonitis-induced adhesions, no limiting toxicity was observed. The results obtained in this small, highly selected series demonstrate that a high PCR rate may be obtained with IP immunochemotherapy with DDP and r-alpha 2-IFN as salvage therapy in residual ovarian carcinoma less than or equal to 5 mm after first-line chemotherapy also including intravenous (IV) DDP. Larger comparative studies must be conducted to establish the potential role of IP DDP and r-alpha 2-IFN as compared with either of the single treatments.
