RESUMO
PURPOSE: This study aimed to evaluate the ability of the percentage of decrease in serum PTH level in the first 8 h after total thyroidectomy (TT) to predict hypocalcemia requiring Ca supplementation and develop a tool to predict it. METHODS: 97 patients who underwent TT with measurement of preoperative parathyroid hormone (PTH) levels were prospectively evaluated 1 and 8 h after TT; postoperative magnesium (Mg2PO) and phosphorus levels were evaluated on the 2nd day after surgery. The percentage of decrease in PTH level 1 h (%dPTH1h) and 8 h (%dPTH8h) postoperatively and predictors of hypocalcemia requiring Ca supplementation were evaluated and an equation was developed to predict this outcome. RESULTS: %dPTH1h (p = 0.002), %dPTH8h (p = 0.001) and (Mg2PO) (p < 0.01) were isolated predictors of postoperative hypocalcemia requiring Ca supplementation. The data obtained led to the development of two tools to predict this complication. CONCLUSIONS: The percentage of decrease in PTH level 1 h and 8 h postoperatively and the magnesium level on the 2nd day after surgery were predictors of more severe hypocalcemia, and an auxiliary tool for predicting this complication was developed.

OBJECTIVES: To identify possible clinical factors associated with hyperthyroidism at presentation and to assess post-evacuation thyroid function in women with complete hydatidiform mole (CHM). METHODS: This observational study included women with CHM attending a specialized Brazilian center in 2002-2018. Clinical and laboratory data (serum hCG, TSH, fT4) were collected at presentation. Factors associated with hyperthyroidism were assessed by logistic regression. Receiver-operating characteristic curves were built to determine the hCG cutoff for predicting hyperthyroidism at CHM presentation. Post-molar evacuation follow-up included clinical assessment and close thyroid function monitoring. RESULTS: Of 137 CHM patients, 69 (50.3%) had hyperthyroidism of any type (43.5% subclinical, 56.5% overt) at presentation. Uterine fundal height > 16 cm or > gestational age (GA), and theca lutein cysts >6 cm were significantly associated with both subclinical and overt hyperthyroidism. The optimal hCG cutoff for predicting hyperthyroidism was 430,559 IU/L (sensitivity 85.5%, specificity 83.8%). Post-evacuation hyperthyroidism/transient hypothyroidism conversion was observed in 13% of the women with hyperthyroidism at presentation. Among the patients not showing conversion to hypothyroidism, median time for TSH normalization was 2 and 3 weeks for subclinical and overt hyperthyroidism, respectively. In the women with overt hyperthyroidism, fT4 was normalized at 2 weeks. CONCLUSIONS: Uterine fundal height > 16 cm, uterine fundal height > GA, theca lutein cysts >6 cm, and hCG >400,000 IU/L at presentation are associated with greater risk of hyperthyroidism and its complications. Close monitoring thyroid function during postmolar follow-up showed that, as thyroid hormones are normalized within 2-3 weeks post-evacuation, the use of beta-blockers or antithyroid drugs can be rapidly discontinued.

PURPOSE: The objective of this study was to evaluate the effects of the Pilates method on quality of life and bone remodeling markers in a group of older women. METHODS: A longitudinal prospective study with intervention was performed on 40 women aged over 60 years; they were divided into two groups: one submitted to a 50-min Pilates exercise session once a week for 20 weeks (Pilates), and the other was not (Control). Both groups were compared for quality of life using the Medical Outcomes Study 36, and for bone-specific alkaline phosphatase (BSAP) and Type 1 collagen C-telopeptide (CTx) bone remodeling markers. RESULTS: The Pilates group presented improvement in the quality of life evaluation scores: physical functioning (67.50 ± 18.88 × 86.25 ± 9.58; p = 0.0232), and physical component summary (65.00 ± 14.39 × 79.70 ± 3.83; p = 0.0220). The Pilates group also presented higher scores than that of Controls after the exercise program: physical functioning (86.25 ± 9.58 × 55.50 ± 20.83, p = 0.0003), physical role (100.00 ± 0.00 × 41.25 ± 46.79, p = 0.0009), emotional role (100.00 ± 0.00 × 48.33 ± 50.12, p = 0.0046), vitality (82.50 ± 14.28 × 60.25 ± 21.43, p = 0.011), physical component summary (79.70 ± 3.83 × 54.90 ± 15.05, p < 0.0001), and emotional component summary (74.10 ± 8.37 × 54.18 ± 22.55, p = 0.0111). No changes were noted in bone remodeling markers [CTx (0.39 ± 0.26 × 0.38 ± 0.22 ng/mL) and BSAP (10.73 ± 2.40 × 11.01 ± 3.56 µg/L)] and did not differ from the Control group both before (CTx: 0.39 ± 0.26 × 0.37 ± 0.17 ng/mL; BSAP: 10.73 ± 2.40 × 10.58 ± 3.49 µg/L; p > 0.05) and after exercise (CTx: 0.38 ± 0.22 × 0.38 ± 0.22 ng/mL; BSAP: 11.01 ± 3.56 × 9.85 ± 3.12 µg/L; p > 0.05). CONCLUSION: The group of women submitted to Pilates presented improved quality of life but without changes in bone remodeling.

BACKGROUND: Stimulated thyroglobulin (STg) levels in patients with differentiated thyroid carcinomas (DTCs) after total thyroidectomy (TT) and before radioactive iodine (131I) ablation/therapy (RIT) are predictive of therapeutic success but can be influenced by the thyroid-stimulating hormone (TSH) level. OBJECTIVES: This study compared the reliability of the STg/TSH ratio and STg measurement in predicting the success of RIT. METHODS: Sixty-three DTC patients submitted to TT were assessed retrospectively to compare the ability of STg level and the STg/TSH ratio to predict successful RIT. RESULTS: In this study 48 (76.2%) patients had successful RIT. The successful and unsuccessful groups received different 131I doses and had different STg levels and STg/TSH ratios. The STg and STg/TSH ratio cutoff values that predicted successful RIT were 4.41 ng/mL (sensitivity of 86.7% and specificity of 77%) and 0.093 (sensitivity of 80% and specificity of 79.2%), respectively. Age, STg level, STg/TSH ratio, and 131I dose were associated with successful RIT, but after multivariate analysis only STg remained associated (p < 0.05). CONCLUSION: In conclusion, our data suggest that the STg/TSH ratio and measurement of STg are equally reliable in predicting successful RIT in DTC patients.

OBJECTIVE: It is not clear whether response to initial treatment in papillary thyroid carcinoma (PTC) patients is best evaluated by measuring thyroglobulin (Tg) in the presence of levothyroxine (BTg) or when stimulated by elevated TSH (STg). The aim of this study was to evaluate whether response to therapy 1 year after initial treatment changes with the use of STg in relation to BTg in PTC patients treated with total thyroidectomy (TT) and radioiodine (131I), and, if observed, to assess which response is better associated with clinical course. SUBJECTS AND METHODS: This is a retrospective study of 148 PTC patients submitted to TT and 131I. We analyzed the response to therapy (excellent, biochemical incomplete, or indeterminate) at 1 year after initial treatment, using BTg or STg, and compared which method was better associated with "excellent response at final evaluation." RESULTS: Twenty-eight patients (20.4%) presented change in response to therapy, with 17 of these (60.7%) presenting a worse response. Response using STg was 1.6 times better associated with proposed outcome [odds ratio (OR) = 4.61; confidence interval 95% (IC95%): 2.13-9.98] than with BTg (OR = 2.84; IC95%: 1.33-6.06). CONCLUSION: Response to therapy at 1 year using STg was altered in approximately 20% of cases and therefore proved to be a better predictor of excellent response in the last evaluation.

Objective: Our aim was to assess the ability of serum magnesium (Mg), measured on the first postoperative day (Mg1PO), to predict the need for calcium (Ca) replacement in patients undergoing total thyroidectomy (TT). Subjects and methods: Eighty patients undergoing TT, with Mg1PO and PTH dosage in the first (PTH1h) and eighth (PTH8h) hours after TT, were evaluated for the need for Ca replacement. Data were evaluated by uni/multivariate logistic regression and Receiver Operating Characteristic (ROC) curve. Results: 32 patients (40%) required Ca replacement. Median PTH1h, PTH8h and Mg1PO were higher in the no replacement group: 17 versus (vs) 3 pg/mL (p < 0.001), 18.2 vs 3.0 pg/mL (p < 0.001) and 2 vs 1.6 mg/dL (p < 0.001), respectively. Mg1PO was the isolated predictor for this replacement (odds ratio = 0.0004, 95% confidence interval: 0.000003-0.04; p = 0.001), with the cut-off value of 1.8 mg/dL showing sensitivity and specificity of 78.1% and 87.5%, respectively. Conclusion: In this group of patients, serum Mg1PO was the isolated predictor for the need for Ca replacement.

Pentalogy of Fallot (PoF) is a congenital heart disease comprising tetralogy of Fallot plus an atrial septal defect (ASD). Patients are diagnosed early in life and submitted to reparative surgery. Without it, the prognosis is poor. This female patient, initially diagnosed with transposition of great arteries (TGA), ASD and a ventricular septal defect, got pregnant at 26 years old and had an early delivery due to fetal distress. She resumed follow-up, and her last echocardiogram put in doubt the diagnosis of TGA. Cardiac CT then revealed a PoF as well as pulmonary arteriovenous fistulas and a persistent left superior vena cava.
RESUMO
Objective: The objective of the study was to determine how physicians in Brazil manage Graves' disease in different scenarios including extrathyroidal manifestations. Materials and methods: This study was conducted via a digital survey. The respondents (n = 573) answered multiple-choice questions based on a clinical case and variations of the case regarding laboratory and imaging evaluation, treatment choice, and follow-up. Results: The preferred initial treatment chosen by 95% of the respondents was ATD with a preferred treatment duration of 18-24 months. For 5% of the respondents, RAI was the initial treatment of choice. None of the respondents chose thyroidectomy. When presented with a patient with a desire for pregnancy in the near future, most respondents (69%) opted for ATD as the initial treatment. For a patient with signs of mild to moderate Graves' orbitopathy, ATD remained the initial therapy for 93.9% of the respondents. For patients initially treated with ATD with disease recurrence after ATD interruption, most respondents (60%) chose definitive treatment with RAI. A similar survey published in 2011 by Burch and cols. had results comparable to those of the present survey but with a higher proportion of respondents choosing RAI (45% in the 2011 survey versus 5% in the present survey). Conclusion: Brazilian endocrinologists choose ATD as the initial management of Graves' disease, and most choose RAI as a definitive treatment for a patient with relapse after ATD therapy.

Primary hypothyroidism is a common disorder in clinical practice. The management of most cases of hypothyroidism is usually straightforward, but the best approach in some special situations may raise questions among physicians. This position statement was prepared by experts from the Brazilian Society of Endocrinology and Metabolism to guide the management of three special situations, namely, hypothyroidism in the elderly, subclinical hypothyroidism in patients with heart disease, and difficult-to-control hypothyroidism. The authors prepared the present statement after conducting a search on the databases MEDLINE/PubMed, LILACS, and SciELO and selecting articles with the best evidence quality addressing the selected situations. The statement presents information about the current approach to patients in these special situations.

Objective: Cytological analysis and Bethesda classification of thyroid nodules is the standard method of diagnosing differentiated thyroid carcinoma (DTC). However, even for nodules with a non-malignant cytological diagnosis, there is a not insignificant risk of cancer. There are doubts whether this lack of certainty would influence patient prognosis. Our aim was to compare patients with DTC, classified according to the preoperative cytological diagnosis, regarding their evolution. Methods: A retrospective study was carried out with 108 DTC patients submitted to total thyroidectomy (TT) between 2009 and 2015, divided into three groups according to preoperative cytological diagnosis (Bethesda classification): classes I/II, III/IV, and V/VI. Groups were compared for evolution considering response to treatment at last evaluation as well as time disease free. Statistical analysis used ANOVA, chi squared, and Kaplan-Meier curves with p<0.05 considered significant. Results: Groups differed for time between nodule puncture and TT [in months; V/VI (2.35 ± 2.48) < III/IV (7.32 ± 6.34) < I/II (13.36 ± 8.9); p < 0.0001]. There was no significant difference between groups for evolution at final evaluation (disease free status; classes I/II: 71.4%; classes III/IV: 60%; classes V/VI: 66.6%; p = 0.7433), as well as time disease free (in months; classes I/II: 34.57 ± 25.82; classes III/IV: 38.04 ± 26.66; classes V/VI: 30.84 ± 26.34; p = 0.3841). Conclusion: DTC patients classified according to preoperative cytological diagnosis did not differ for evolution. Although patients with non-malignant cytological diagnoses were submitted to TT later, this did not affect the evolution of the cases.

INTRODUCTION: Hypocalcemia is one of the most common complications after total thyroidectomy. Preoperative serum vitamin D concentration has been postulated as a risk factor for this complication. However, the subject is still controversial and the role of vitamin D in the occurrence of hypocalcemia remains uncertain. OBJECTIVE: To evaluate the capability of preoperative vitamin D concentrations in predicting post-total thyroidectomy hypocalcemia. METHODS: Forty-seven total thyroidectomy patients were prospectively evaluated for serum 25(OH) vitamin D, calcium and parathyroid hormone before surgery, Calcium every 6â¯hours, and parathyroid hormone 8â¯hours post-operatively. Patients were divided according to postoperative corrected calcium into groups without (corrected calcium ≥8.5â¯mg/dL) and with hypocalcemia (corrected calcium <8.5â¯mg/dL), who were then evaluated for preoperative 25(OH) vitamin D values. RESULTS: A total of 72.3% of cases presented altered 25(OH) vitamin D preoperative serum concentrations and 51% evolved with postoperative hypocalcemia. The with and without hypocalcemia groups did not differ for preoperative 25(OH) vitamin D (pâ¯=â¯0.62). Univariate analysis showed that age (pâ¯=â¯0.03), postoperative PTH concentration (pâ¯=â¯0.02), and anatomopathological diagnosis of malignancy (pâ¯=â¯0.002) were predictors of postoperative hypocalcemia. In multivariate analysis only parathyroid hormone in postoperative (pâ¯=â¯0.02) was associated with post-total thyroidectomy hypocalcemia. CONCLUSION: Preoperative serum concentrations of 25(OH) vitamin D were not predictors for post-total thyroidectomy hypocalcemia, whereas postoperative parathyroid hormone influenced the occurrence of this complication.

OBJECTIVE: To evaluate whether there is a relationship between diet quality and bone health in a group of elderly Brazilian women. METHODS: A cross-sectional study was performed with 105 elderly women. Participants were evaluated regarding diet quality (good, needing improvement, and poor) and its relationship with bone mineral density (BMD), bone-specific alkaline phosphatase (BSAP), and C-telopeptide (CTX). RESULTS: Fifty eight participants (55.2%) presented a poor-quality diet and 47 (44.8%) required dietary improvements, while no subjects presented a good quality diet. The group requiring dietary improvements had lower CTX [0.35 (0.05;1.09) vs. 0.52 (0.10;1.45); p = 0.03)] and BSAP (38.7 ± 12.9 U/L vs. 46.10 ± 15.2 U/L; p < 0.01) levels than the poor-quality diet group. Groups did not differ in terms of BMD. CONCLUSION: In this group of elderly Brazilian women, there was a relationship between diet quality and bone health, where worse diet quality was associated with higher levels of bone remodelling markers.

OBJECTIVE: Follicular lesions of the thyroid with papillary carcinoma nuclear characteristics are classified as infiltrative follicular variant of papillary thyroid carcinoma-FVPTC (IFVPTC), encapsulated/well demarcated FVPTC with tumour capsular invasion (IEFVPTC), and the newly described category "non-invasive follicular thyroid neoplasm with papillary-like nuclear features" (NIFTP) formerly known as non-invasive encapsulated FVPTC. This study evaluated whether computerized image analysis can detect nuclear differences between these three tumour subtypes. METHODS: Slides with histological material from 15 cases of NIFTP and 33 cases of FVPTC subtypes (22 IEFVPTC, and 11 IFVPTC) were analyzed using the Image J image processing program. Tumour cells were compared for both nuclear morphometry and chromatin textural characteristics. RESULTS: Nuclei from NIFTP and IFVPTC tumours differed in terms of chromatin textural features (grey intensity): mean (92.37 ± 21.01 vs 72.99 ± 14.73, p = 0.02), median (84.93 ± 21.17 vs 65.18 ± 17.08, p = 0.02), standard deviation (47.77 ± 9.55 vs 39.39 ± 7.18; p = 0.02), and coefficient of variation of standard deviation (19.96 ± 4.01 vs 24.75 ± 3.31; p = 0.003). No differences were found in relation to IEFVPTC. CONCLUSION: Computerized image analysis revealed differences in nuclear texture between NIFTP and IFVPTC, but not for IEFVPTC.

OBJECTIVE: Thyrotropin-stimulated thyroglobulin (STg) after total thyroidectomy is a prognosis marker for differentiated thyroid carcinoma (DTC). As Tg level is influenced by thyrotropin (TSH), perhaps the STg/TSH ratio is also a prognosis marker for these tumours. We aimed to compare STg/TSH ratio and first STg level in differentiated thyroid carcinoma patients for their ability to predict the long-term response to initial treatment. METHODS: This retrospective study evaluated data from 181 DTC patients for first (1st) STg and STg/TSH ratio, at 1-3 months post-total thyroidectomy and before iodine-131 therapy, according to response to initial therapy [Excellent/Indeterminate or Incomplete (Biochemical/Structural)] observed at final evaluation, and with the survival time with excellent/indeterminate response. RESULTS: Cases with incomplete response presented higher STg level [225.13 ± 585.26 ng/mL versus (vs) 20.4 ± 192.9 ng/mL; p < 0.001] and STg/TSH ratio (3.01 ± 7.8 vs 0.27 ± 2.58; p < 0.001). Cutoffs of 5 ng/mL for STg and 0.085 for STg/TSH displayed sensitivities of 76.7% and 76.9%, and specificities of 79.2% and 82.6%, respectively, in predicting response to therapy. Values below these cutoffs were associated with longer survival time in excellent/indeterminate response (140.4 vs 15.9 and 144.6 vs 15.9 months, respectively). CONCLUSION: STg/TSH ratio has a similar performance to the 1st STg in predicting long-term response to initial therapy.

BACKGROUND: Thyroid nodules diagnosed as 'atypia of undetermined significance/follicular lesion of undetermined significance' (AUS/FLUS) or 'follicular neoplasm/suspected follicular neoplasm' (FN/SFN), according to Bethesda's classification, represent a challenge in clinical practice. Computerized analysis of nuclear images (CANI) could be a useful tool for these cases. Our aim was to evaluate the ability of CANI to correctly classify AUS/FLUS and FN/SFN thyroid nodules for malignancy. METHODS: We studied 101 nodules cytologically classified as AUS/FLUS (n = 68) or FN/SFN (n = 33) from 97 thyroidectomy patients. Slides with cytological material were submitted for manual selection and analysis of the follicular cell nuclei for morphometric and texture parameters using ImageJ software. The histologically benign and malignant lesions were compared for such parameters which were then evaluated for the capacity to predict malignancy using the classification and regression trees gini model. The intraclass coefficient of correlation was used to evaluate method reproducibility. RESULTS: In AUS/FLUS nodule analysis, the benign and malignant nodules differed for entropy (P < 0.05), while the FN/SFN nodules differed for fractal analysis, coefficient of variation (CV) of roughness, and CV-entropy (P < 0.05). Considering the AUS/FLUS and FN/SFN nodules separately, it correctly classified 90.0 and 100.0% malignant nodules, with a correct global classification of 94.1 and 97%, respectively. We observed that reproducibility was substantially or nearly complete (0.61-0.93) in 10 of the 12 nuclear parameters evaluated. CONCLUSION: CANI demonstrated a high capacity for correctly classifying AUS/FLUS and FN/SFN thyroid nodules for malignancy. This could be a useful method to help increase diagnostic accuracy in the indeterminate thyroid cytology.
RESUMO
OBJECTIVE: Choosing Wisely (CW) is an initiative that aims to advance the dialogue between physicians and patients about low-value health interventions. Given that thyroid conditions are frequent in clinical practice, we aimed to develop an evidence-based list of thyroid CW recommendations. METHODS: The Thyroid Department of the Brazilian Society of Endocrinology and Metabolism (SBEM) named a Task Force to conduct the initiative. The Task Force work was based on an electronic Delphi approach. The 10 recommendations that received the highest scores by the Task Force were submitted for voting by all SBEM associates. The 5 recommendations that received the highest scores by SBEM associates are presented herein. RESULTS: The Task Force was composed of 14 thyroidologists from 10 tertiary-care, teaching-based Brazilian institutions. The brainstorming/ideation phase resulted in 69 recommendations. After the removal of duplicates and recommendations that did not adhere to the initiative's scope, 35 remained. Then the Task Force voted to attribute a grade (0 [lowest agreement] to 10 [highest agreement]) for each recommendation. The 10 recommendations that received the highest scores by the Task Force were submitted to all SBEM associates. A total of 683 associates voted electronically, attributing a grade (0 to 10) for each recommendation. The 5 recommendations that received the highest scores by the SBEM associates compose our final list. CONCLUSION: A set of recommendations to avoid unnecessary medical tests, treatments, or procedures for thyroid conditions are offered with a transparent methodology. This initiative aims to foster productive interactions between physicians and patients, stimulating shared decision-making.

The present study aimed to understand patients experience with osteoporosis treatment. The methodological and theoretical frameworks were, respectively, the Grounded Theory and Symbolic Interactionism. The research subjects were 12 patients monitored in a specialized outpatient unit. The obtained statements were transcribed and analyzed, leading to a synthesis of the described themes. From the analysis process, two phenomena emerged: self-evaluating health conditions according to the disease signs and making a decision about the treatment targeting at well-being. The realignment and the inter-relationship of the components belonging to these phenomena (themes, categories, and subcategories) allowed to identify the core category: self-managing osteoporosis treatment for well-being recovery mediated by the (in)visibility of the disease signs. Furthermore, it allowed for the design of a theoretical model concerning the process used by the player in his cyclic movement of the experience, between adherence to and relaxation from the osteoporosis treatment.

INTRODUCTION: Endogenous thyroid-stimulating hormone-stimulated thyroglobulin collected after total thyroidectomy is a useful predictor of better prognosis in patients with differentiated thyroid carcinomas in general, but studies with microcarcinomas are scarce. OBJECTIVE: To assess whether the first postoperative stimulated thyroglobulin measurement is a prognostic factor in patients with microcarcinoma. METHODS: The medical data of 150 differentiated thyroid carcinoma patients were studied retrospectively, and 54 (36%) cases with microcarcinoma were selected. The first postoperative stimulated thyroglobulin (1st stimulated thyroglobulin), measured after thyroidectomy, initial presentation data, and microcarcinomas treatment were assessed regarding outcome. Worse prognosis was defined as neoplasm persistence/recurrence. RESULTS: Persistence/recurrence occurred in 27.8% of the cases. These patients were identified according to the following parameters: receiving more than one 131iodine dose (100% vs. 0%; p<0.0001); accumulated 131iodine dose (232.14±99.09 vs. 144±33.61mCi; p<0.0001); presented active disease in the last assessment (53.3% vs. 0%; p<0.0001); follow-up time (103.07±61.27 vs. 66.85±70.14 months; p=0.019); and 1st stimulated thyroglobulin (19.01±44.18 vs. 2.19±2.54ng/dL; p<0.0001). After multivariate logistic regression, only the 1stSTg [odds ratio=1.242; 95% confidence interval: 1.022-1.509; p=0.029] and follow-up time (odds ratio=1.027; 95% confidence interval: 1.007-1.048; p=0.007) were independent predictors of risk of persistence/recurrence. The cutoff point of 1.6ng/dL for the 1st stimulated thyroglobulin was significantly associated with disease persistence/recurrence [area under the curve=0.713 (p=0.019)]. CONCLUSION: The first stimulated thyroglobulin predicted disease persistence/recurrence in patients with microcarcinoma.

INTRODUCTION: In hypoparathyroidism, calcium supplementation using calcium carbonate is necessary for the hypocalcemia control. The best calcium carbonate intake form is unknown, be it associated with feeding, juice or in fasting. OBJECTIVE: The objective was to evaluate the calcium, phosphorus and calcium×phosphorus product serum levels of hypoparathyroidism women after total thyroidectomy, following calcium carbonate intake in three different forms. METHODS: A crossover study was carried out with patients presenting definitive hypoparathyroidism, assessed in different situations (fasting, with water, orange juice, breakfast with a one-week washout). Through the review of clinical data records of tertiary hospital patients from 1994 to 2010, 12 adult women (18-50 years old) were identified and diagnosed with definitive post-thyroidectomy hypoparathyroidism. The laboratory results of calcium and phosphorus serum levels dosed before and every 30min were assessed, for 5h, after calcium carbonate intake (elementary calcium 500mg). RESULTS: The maximum peak average values for calcium, phosphorus and calcium×phosphorus product were 8.63mg/dL (water), 8.77mg/dL (orange juice) and 8.95mg/dL (breakfast); 4.04mg/dL (water), 4.03mg/dL (orange juice) and 4.12mg/dL (breakfast); 34.3mg2/dL2 (water), 35.8mg2/dL2 (orange juice) and 34.5mg2/dL2 (breakfast), respectively, and the area under the curve 2433mg/dLmin (water), 2577mg/dLmin (orange juice) and 2506mg/dLmin (breakfast), 1203mg/dLmin (water), 1052mg/dLmin (orange juice) and 1128mg/dLmin (breakfast), respectively. There was no significant difference among the three different tests (p>0.05). CONCLUSION: The calcium, phosphorus and calcium×phosphorus product serum levels evolved in a similar fashion in the three calcium carbonate intake forms.

The diagnostic and therapeutic approach for pregnant women with thyroid nodules can present a challenge, especially concerning surgical procedures. In the context of malignant diagnosis, by fine needle aspiration (FNA), during pregnancy, the uncertainty lies in performing surgery. This article reports the case of a 41-year-old pregnant woman in her first gestation, who sought medical care complaining of right shoulder pain. Imaging workup depicted the destruction of the humeral head and involvement of the surrounding soft tissue. She was 20 weeks pregnant. The histological report favored the diagnosis of malignancy and the thyroid as the primary site. At 30 weeks of gestation, the patient underwent a cesarean section, a total thyroidectomy, and total resection of the metastasis. The child was born healthy, but one year after the diagnosis, the patient died. Bone and soft tissue metastasis of thyroid neoplasms are not very common and indicate poor prognosis.
