Impact of systemic treatments for advanced thyroid cancer on the adrenal cortex.

Background: Fatigue is a frequent adverse event during systemic treatments for advanced thyroid cancer, often leading to reduction, interruption, or discontinuation. We were the first group to demonstrate a correlation between fatigue and primary adrenal insufficiency (PAI). Aim: The objective was to assess the entire adrenal function in patients on systemic treatments. Methods: ACTH, cortisol and all the hormones produced by the adrenal gland were evaluated monthly in 36 patients (25 on lenvatinib, six on vandetanib, and five on selpercatinib). ACTH stimulation tests were performed in 26 cases. Results: After a median treatment period of 7 months, we observed an increase in ACTH values in 80-100% of patients and an impaired cortisol response to the ACTH test in 19% of cases. Additionally, dehydroepiandrosterone sulphate, ∆-4-androstenedione and 17-OH progesterone levels were below the median of normal values in the majority of patients regardless of the drug used. Testosterone in females and oestradiol in males were below the median of normal values in the majority of patients on lenvatinib and vandetanib. Finally, aldosterone was below the median of the normal values in most cases, whilst renin levels were normal. Metanephrines and normetanephrines were always within the normal range. Replacement therapy with cortisone acetate improved fatigue in 14/17 (82%) patients with PAI. Conclusion: Our data confirm that systemic treatments for advanced thyroid cancer can lead to impaired cortisol secretion. A reduction in the other hormones secreted by the adrenal cortex has been first reported and should be considered in the more appropriate management of these fragile patients.

Management of hypertension during lenvatinib for advanced thyroid cancer: a suggested diagnostic and therapeutic algorithm.

Background: Hypertension (HTN) is the most frequent adverse event during treatment with lenvatinib (LEN), but data on its best management are limited. Aim: The objective of this study was to assess incidence, features and best management of LEN-related HTN in a consecutive single tertiary-care centre cohort. Methods: Twenty-nine patients were followed up for a mean time of 29.8 months (6-77 months). Results: After a mean follow-up of 6.8 months, HTN was recorded in 76% of cases, as a de novo occurrence in half of them. HTN significantly correlated with LEN dose and was of grade 1, grade 2 and grade 3 in 5%, 50% and 45% of patients, respectively. The majority (77%) of patients with HTN developed proteinuria. There was no correlation between HTN and proteinuria or clinical features or best morphological response or any other adverse event (AE), with the exception of diarrhoea. Patients with or without pre-existing HTN or any other cardiovascular disease had a similar incidence of HTN during LEN, thus excluding the impact of this potential predisposing factor. After evaluation by a dedicated cardiologist, medical treatment was introduced in 21/22 patients (polytherapy in 20 of them). The most frequently used drugs were calcium channel blockers (CCBs) due to their effect on vasodilation. In case of poor control, CCBs were associated with one or more anti-hypertensive drug. Conclusion: HTN is a frequent and early AE in patients on LEN treatment. We suggest a diagnostic and therapeutic algorithm to be applied in clinical practice to allow efficient HTN control and improve patient compliance, reducing LEN discontinuation.

Endocrine-related adverse conditions induced by tyrosine kinase inhibitors.

Tyrosine kinase inhibitors (TKIs) have improved outcome for many tumors. Although better tolerated than cytotoxic chemotherapy, they may cause several adverse events (AEs) and various endocrine-related toxicities have been reported under TKI treatment. The toxicity profile varies between the different TKI compounds. This review focuses on the main endocrinopathies caused by TKIs. Thyroid dysfunction and, in particular, hypothyroidism are the most frequent and best described. Several potential mechanisms have been hypothesized, including thyroid gland dysfunction, hormone metabolism impairment and hypothalamus-pituitary-thyroid axis imbalance. TKIs have been reported to influence almost all glands. In particular, they are associated with adrenal insufficiency, growth retardation due to growth hormone (GH) and/or insulin-like growth factor-1 (IGF1) deficiency, hypogonadism, and male and female fertility impairment. TKIs may affect bone metabolism, in particular decreasing osteoclastogenesis and bone turnover and, in turn, they may cause secondary hyperparathyroidism. Hypocalcemia has been reported under lenvatinib and vandetanib treatment and parathyroid hormone (PTH)-dependent and PTH-independent mechanisms have been hypothesized. Metabolic alterations during TKI treatment range from hypoglycemia with imatinib and dasatinib to hyperglycemia with nilotinib; dyslipidemia improved with imatinib and worsened with nilotinib, sunitinib, pazopanib, sorafenib, and famitinib. Endocrine-related AEs should be managed by dedicated endocrinologists. Hormone deficiencies are easily managed by replacement therapy, while endocrine hyperfunction may be improved by symptomatic treatment. Severe situations should be managed in coordination with the oncologist, trying to limit the need for TKI dose reduction or interruption.

Oral ibuprofen versus oral ketorolac for children with moderate and severe acute traumatic pain: a randomized comparative study.

This study is to compare ibuprofen and ketorolac for children with trauma-related acute pain. We conducted a multicentre randomized, double-blind, controlled trial in the Paediatric Emergency Department setting. We enrolled patients aged 8 to 17 who accessed the emergency department for pain related to a limb trauma that occurred in the previous 48 h. At the admission, patients were classified based on numeric rating scale-11 (NRS-11) in moderate (NRS 4-6) and severe (NRS 7-10) pain groups. Each patient was randomized to receive either ibuprofen (10 mg/kg) or ketorolac (0.5 mg/kg) and the placebo of the not given drug in a double dummies design. NRS-11 was asked every 30 min until 2 h after drug and placebo administration. The primary outcome was NRS-11 reduction at 60 min. Among 125 patients with severe pain, NRS-11 reduction after 60 min from drug administration was 2.0 (IQR 1.0-4.0) for ibuprofen and 1.0 (IQR 1.0-3.0) for ketorolac (p = 0.36). Ibuprofen was significantly better, considering secondary outcomes, at 90 min with a lower median of NRS-11 (p 0.008), more patients with NRS-11 less than 4 (p 0.01) and a reduction of pain score of more than 3 NRS-11 points (p 0.01). Among 87 patients with moderate pain, the NRS-11 reduction after 60 min from drug administration was 1.63 (± 1.8) for ibuprofen and 1.8 (± 1.6) for ketorolac, with no statistically significant difference.Conclusions: Oral ibuprofen and ketorolac are similarly effective in children and adolescents with acute traumatic musculoskeletal pain.Trial registration: ClinicalTrial.gov registration number: NCT04133623.

Hypocalcemia During Lenvatinib Treatment for Advanced Thyroid Cancer: Clinical Features and Management in a Real-Life Setting.

Background: Several toxicities are recorded during treatment of advanced thyroid cancer (TC) with antiangiogenic drugs, including lenvatinib (LEN). Hypocalcemia was reported in registration studies, but little data are available from real-life cohorts. The aim of our study was to describe the incidence, characteristics, and the management of hypocalcemia in patients on LEN treatment. Methods: This is a retrospective cohort study of consecutive patients with advanced TC, treated with LEN for at least six months at a single tertiary center in Italy. Phosphocalcic metabolism was evaluated during treatment. Results: We included 25 patients treated for a mean of 29 ± 19 months (range 6-68 months). Hypocalcemia occurred in 6 of the 25 patients (24% [95% confidence interval 9.36-45.13%]), being of grade ≥3 in 2 of the 25 patients (8%), and recurrent in 4 of 6 patients (67%). The median time to hypocalcemia onset was 3 months (range 0.5-13 months) from starting LEN. No differences were found between patients who developed or not hypocalcemia regarding either starting/mean dose of LEN or clinicopathological characteristics. During the hypocalcemic crisis, the 2 patients with grade ≥3 hypocalcemia had low magnesium and low or inappropriately normal parathormone (PTH) levels, while 2 of 3 patients with grade 2 hypocalcemia had a secondary hyperparathyroidism. Hypocalcemia was managed with calcium oral supplementation in most cases, although up to 10% of patients required intravenous calcium treatment and transient LEN withdrawal. Conclusions: In this relatively small cohort, we observed an incidence of hypocalcemia of 24%, which is higher than that reported in the registration trial (6.9%). Both PTH-dependent and PTH-independent mechanisms explained hypocalcemia in the present cohort. Monitoring of serum calcium levels is strongly advised during the first year of LEN treatment, as hypocalcemia may be severe. More research is needed to confirm our findings and inform possible risk factors for hypocalcemia in advanced TC patients treated with LEN.

Persistent Thyroid Carcinoma and Pregnancy: Outcomes in an Italian Series and Review of the Literature.

Scanty data are available on the progression risk in patients with persistent thyroid cancer (TC) before pregnancy. We aimed to evaluate this topic in our series and to review available literature data. This was a retrospective study performed in a tertiary care Italian TC center. We included 8 patients with persistent papillary TC who became pregnant after initial treatments (mean time interval of 62 months). Seven patients had the structural disease (lung and/or neck node metastases), while one patient had biochemical persistence. During a mean follow-up of 97 months, none of the patients showed disease progression either during pregnancy or during a follow-up of at least 12 months after delivery, and no additional treatments were needed. A sequential biochemical evaluation showed that thyroglobulin levels can significantly increase during pregnancy, returning to preconception levels after delivery. In conclusion, our data confirm that pregnancy is not associated with disease progression in patients with stable local and/or distant persistence before conception. Thus, pregnancy should not be contraindicated in metastatic women, although a precise clinical characterization, including the disease stage at diagnosis, the ATA risk class, and the dynamic risk stratification, should be conducted before conception.

SGLT2-inhibitors are effective and safe in the elderly: The SOLD study.

BACKGROUND AND AIMS: Sodium-glucose co-transporter-2 inhibitors (SGLT2i) may have important benefits for the elderly with type 2 diabetes (T2D), however some safety concerns still limit their use in patients over 70 years of age. The SOLD study (SGLT2i in Older Diabetic patients) is a multicenter study, aimed to evaluate the effectiveness and safety of SGLT2i in the older diabetic patients in a real-life setting. MATERIALS AND METHODS: We analyzed a population of 739 adults (mean age 75.4 ± 3.9 years, M/F 420/319) with T2D, which started a SGLT2i-based treatment after the age of 70, with at least one year of follow-up. Data were collected at baseline, at 6 and 12 months of follow-up. RESULTS: SGLT2i (37.5% Empagliflozin, 35.7% Dapagliflozin, 26.1% Canagliflozin, 0.7% Ertugliflozin) were an add-on therapy to Metformin in 88.6%, to basal insulin in 36.1% and to other antidiabetic drugs in 29.6% of cases. 565 subjects completed the follow up, while 174 (23.5%) discontinued treatment due to adverse events which were SGLT2i related. A statistically significant reduction of glycated hemoglobin (baseline vs 12 months: 7.8 ± 1.1 vs 7.1 ± 0.8%, p < 0.001) and body mass index values (baseline vs 12 months: 29.2 ± 4.7 vs 28.1 ± 4.5 kg/m2, p < 0.001) were evident during follow-up. Overall, estimated glomerular filtration rate remained stable over time, with significant reduction of urinary albumin excretion. In the subgroup of patients which were ≥ 80 years, a significant improvement in glycated hemoglobin values without renal function alterations was evident. Overall discontinuation rate during the follow-up period was different across age groups, being urinary tract infections and worsening of renal function the most common cause. CONCLUSION: SGLT2i are well-tolerated and safe in the elderly and appear as an effective therapeutic option, though some caution is also suggested, especially in more fragile subjects.

"Shoulder pain and limitation of motion in a young girl: think different".

BACKGROUND: Primary Synovial Chondromatosis (PSC) is a rare benign tumor of the synovial membrane in which cartilage metaplasia produces calcific loose bodies within the articular space. Only a few cases are reported in the pediatric population and its etiology remains unknown. This condition typically affects large weight-bearing joints with pain, swelling and decrease range of motion. Due to its slow progressions, delayed diagnosis is frequent and differential diagnosis should consider other chronic arthritis and malignancies. While arthroscopic removal of loose bodies is the current treatment up to now, the association of partial or complete synovectomy is debated. CASE PRESENTATION: We report about a 14-year-old girl with a long-lasting right shoulder pain, especially during movements or exercise, localized tenderness and hypotonia of the glenohumeral joint. No previous trauma was mentioned. Blood exams, Mantoux test and plain radiography of the right shoulder were unremarkable. Ultrasound imaging revealed echogenic and calcified bodies stretching the glenohumeral joint and dislocating the long head of biceps tendon. Magnetic resonance showed a "rice-grain" pattern of the right shoulder. From an arthroscopic surgery, multiple loose white bodies were removed within the synovial membrane, and synovial chondromatosis was confirmed by histological analysis. At one month follow up visit, the patient completely recovered without pain. CONCLUSION: Synovial chondromatosis is a very uncommon cause of mono articular pain in children, especially when it affects shoulder. Pediatricians should keep in mind this condition to avoid delayed diagnosis and treatment, even in consideration of the low risk of malignant transformation. Through this case, we would highlight common diagnostic pitfalls and treatment of synovial chondromatosis.

Daily Management of Patients on Multikinase Inhibitors' Treatment.

In a minority of differentiated thyroid cancer (TC) cases and in a large percentage of poorly differentiated TCs (PDTCs) and anaplastic TCs (ATCs), the prognosis is poor due to the lack of response to conventional treatments. In the last two decades, multikinase inhibitor (MKI) compounds have been developed and demonstrated to be very effective in these aggressive cases. Besides the great efficacy, several adverse events (AEs) have been reported in virtually all patients treated with MKIs, largely overlapping between different compounds and including hypertension, diarrhea, anorexia, decreased weight, fatigue, and proteinuria. Most grade 3-4 adverse reactions occur during the first 6 months of treatment and require dosage reduction and/or drug discontinuation. Due to severity of the AEs related to the treatment with MKIs, a multidisciplinary team is definitely required for the daily management of these patients, for the evaluation of the disease status, and the psychophysical condition. Moreover, it is crucial that the patients could have a facilitated access to reach either specialist doctors or nurses who must have been trained to follow them for their individual clinical complications. The follow-up visits should take place at monthly intervals until the sixth month and then every 1-2 months until the completion of the first year of treatment. The flow chart followed at our tertiary center is reported in the present review as a real-life-based example for the follow-up of patients with advanced TC on MKI treatment.

Lenvatinib-induced hypocalcaemia due to transient primary hypoparathyroidism.

CONTEXT: Radioiodine refractory differentiated thyroid cancer can be effectively treated with multi-tyrosine-kinase inhibitors (MKIs). Hypocalcaemia has been reported among the side effects of these drugs, but little is known about its pathophysiology and clinical relevance. CASE REPORT: We report the case of a 78-years-old woman with an aggressive papillary thyroid cancer infiltrating perithyroidal structures. The extent of surgery was limited to hemithyroidectomy, RAI treatment could not be performed, and she started lenvatinib treatment. After 4 months of therapy, the patient accessed the Emergency Department for a grade III hypocalcaemia (corrected serum calcium: 6.6 mg/dL, n.v. 8.1-10.4 mg/dL), due to primary hypoparathyroidism (serum PTH: 12.6 ng/L, n.v. 13-64 ng/L). The patient was treated with intravenous calcium infusions and vitamin D supplementation. After discharge, the oral dose of carbonate calcium (CaCO3) was of 6 g/day, and was titrated according to blood exams. Two weeks after discharge, while taking CaCO3 at the dose of 3 g/day, the patient experienced symptomatic grade II hypercalcemia (corrected serum calcium: 11.6 mg/dL), associated to the spontaneous reprise of PTH secretion, and leading to oral calcium withdrawal. During the subsequent follow-up, the patient remained eucalcemic without calcium supplementation. CONCLUSIONS: Though hypocalcaemia has been described as potential side effect of MKI treatment, this is the first report of a lenvatinib-induced primary hypoparathyroidism, in a patient with a documented normal parathyroid function after surgery. The periodical assessment of calcium-phosphorus metabolism is thus warranted to prevent this potentially lethal side effect, in both post-surgical hypoparathyroid and euparathyroid patients.

Loss of Continuity of Care in Pediatric Neurology Services during COVID-19 Lockdown: An Additional Stressor for Parents.

Background. This study aimed to investigate the consequence of the COVID 19-related lockdown on the well-being of children with neurological and neurodevelopmental disorders and the repercussion on parental stress during the period 9 March 2020-3 May 2020. Methods. A web-based survey was shared via mail with the parents of children affected by chronic neurologic disorders and neurodevelopmental disorders in the continuity of care in two Italian tertiary centers, independently by the severity of the diseases and the required frequency of controls. For each patient, they were asked to identify a single main caregiver, among the two parents, to fill in the questionnaire. Parental stress was measured via the Perceived Stress Scale (PSS). Statistical analysis was performed with IBM SPSS Statistics version 25. The differences between the clinical groups were performed with one way ANOVA. The dimensional effect of the clinical variables on outcome was evaluated by multiple linear regression analysis. Results. The survey was completed by 250 parents (response rate = 48.9 %). Sars-Cov2 infection was reported in two patients only. A total of 44.2% of the patients had completely interrupted school activities while 70% of parents underwent changes in their job modalities. Health care services were disrupted in 77% of patients. Higher PSS scores were detected in the parents of children with neurodevelopmental disorders (p = 0.035). Conclusions. The loss of continuity of care during the lockdown must be considered as a risk factor for parents caring for children with chronic neurologic diseases and neurodevelopmental disorders in further phases of the current pandemic.

Case Report: Simil-Appendicitis Presentation May Precede Cardiac Involvement in MIS-C Patient.

Introduction: Multisystem inflammatory syndrome in children (MIS-C) is a new clinical entity characterized by a systemic hyperinflammation triggered by SARS-CoV-2 infection in children and adolescents. This condition could potentially involve all organs with main complications concerning cardiovascular system. Despite up to 90% of patients complain gastrointestinal symptoms (nausea, vomit, and diarrhea), a presentation mimicking acute appendicitis has rarely been reported, and can be the presenting feature of the disease, potentially leading to misdiagnosis and delayed treatment. Case Description: A 15-year-old boy presented to the Emergency Department for a 2-day history of fever, vomiting, and mild abdominal pain. One month before, the patient complained ageusia and anosmia while his mother tested positive for Sars-CoV2 nasopharyngeal swab. At admission, laboratory tests showed leukocytosis with lymphopenia and elevation of inflammatory markers, while cardiac enzymes, electrocardiogram and echocardiography were unremarkable. An abdominal ultrasound displayed a thickening of terminal ileus and cecum with ascites. Because of the worsening abdominal pain and a physical examination suggestive of acute appendicitis, a laparoscopy was performed but no surgical condition was found. After surgery, fever and generalized malaise persisted, so a cardiac evaluation was repeated, showing a relevant increase in inflammatory markers and cardiac enzymes. Electrocardiogram demonstrated a QTc prolongation with mild decrease in left ventricular ejection fraction at echocardiogram. A MIS-C was diagnosed and intravenous immunoglobulin along with a steroid treatment started. After 36 h, the patient presented a complete clinical recovery with fever cessation. Cardiac anomalies normalized in 3 weeks. Conclusion: MIS-C has been defined as a systemic inflammation, involving at least two organs, after a previous SARS-CoV2 infection in children and adolescents. Physicians should be aware that while gastrointestinal manifestations are common, a pseudo appendicitis presentation may also occur, leading to misdiagnosis and delayed treatment. This report suggests that in patients with symptoms suggestive of an acute appendicitis, the presence of lymphopenia, hypoalbuminemia and ultrasound images of terminal ileus inflammation, should raise the suspect for MIS-C even without initial overt signs of cardiac involvement.

Post-Surgical Ablative or Adjuvant Radioiodine Therapy Has No Impact on Outcome in 1-4 cm Differentiated Thyroid Cancers without Extrathyroidal Extension.

Whether to conduct remnant ablation or adjuvant radioactive iodine (RAI) therapy in patients with intrathyroidal differentiated thyroid carcinoma (DTC), sized 1.1-4 cm, is debated. We evaluated the impact of RAI on outcome in this category of DTCs. We retrospectively enrolled 308 patients submitted to total thyroidectomy: 198 had tumors sized 1.1-2 cm (Group 1) and 110 of 2.1-4 cm (Group 2). Both groups were divided into patients receiving and not receiving RAI after surgery. RAI+ and RAI- patients did not significantly differ, regarding several clinical and pathological features. Final outcome was defined according to dynamic risk stratification. Remission was observed in the majority of Group 1 and Group 2 patients and outcome did not significantly differ between RAI+ and RAI- patients: respectively, 95.8% vs. 93.7% in Group 1, and 87.7% vs. 86.5% in Group 2. The majority of persistent cases, either RAI+ or RAI-, received therapeutic RAI administration, and about 50% of RAI- cases had an excellent response at final follow up, whereas no RAI+ persistent patients had a beneficial effect. Our findings demonstrate that patients with an intrathyroidal DTC sized 1.1-4 cm do not benefit from RAI. The outcome of these patients remains favorable, and the few patients with persistent diseases can be treated with RAI during follow up.

Total Thyroidectomy Versus Lobectomy for Thyroid Cancer: Single-Center Data and Literature Review.

BACKGROUND: Controversies remain about the ideal risk-based surgical approach for differentiated thyroid cancer (DTC). METHODS: At a single tertiary care institution, 370 consecutive patients with low- or intermediate-risk DTC were submitted to either lobectomy (LT) or total thyroidectomy (TT) and were followed up. RESULTS: Event-free survival by Kaplan-Meier curves was significantly higher after TT than after LT for the patients with either low-risk (P = 0.004) or intermediate-risk (P = 0.032) tumors. At the last follow-up visit, the prevalence of event-free patients was higher in the TT group than in the LT low-risk group (95% and 87.5%, respectively; P = 0.067) or intermediate-risk group (89% and 50%; P = 0.008). No differences in persistence prevalence were found among microcarcinomas treated by LT or TT (low risk, P = 0.938 vs. intermediate-risk, P = 0.553). Nevertheless, 15% of the low-risk and 50% of the intermediate-risk microcarcinomas treated by LT were submitted to additional treatments. On the other hand, macrocarcinomas were significantly more persistent if treated with LT than with TT (low-risk, P = 0.036 vs. intermediate-risk, P = 0.004). Permanent hypoparathyroidism was more frequent after TT (P = 0.01). After LT, thyroglobulin (Tg)/thyroid-stimulating hormone (TSH) had shown decreasing trend in 68% of the event-free patients and an increasing trend in the persistent cases. CONCLUSIONS: Lobectomy can be proposed for low-risk microcarcinomas, although in a minority of cases, additional treatments are needed, and a longer follow-up period usually is required to confirm an event-free outcome compared with that for patients treated with TT. On the other hand, to achieve an excellent response, TT should be favored for intermediate-risk micro- and macro-DTCs despite the higher frequency of postsurgical complications.
