Inflammatory bowel disease: an increased risk factor for recurrent laryngeal nerve palsy in thyroid surgery
Transient or permanent recurrent laryngeal nerve palsy is a well known complication in thyroid surgery with reported incidences of 5-8%
and 1-3%, respectively 1. Diplegia has an incidence of 0.4% 2. Inflammatory bowel disease (IBD) is an important cause of peripheral neurosensitivity,
particularly autonomic neuropathy, which can lead to transient or permanent laryngeal nerve palsy when neural structures are
involved during surgery. Several mechanisms have been implicated in the physiopathology of these neurological disorders, but the actual
mechanism is still unknown. Herein we report on two patients with IBD presenting with transient bilateral recurrent laryngeal nerve palsy
after total thyroidectomy without any evident mechanical or traumatic manoeuvres on apparently preserved nerves
Baseline serum TSH levels predict the absence of thyroid dysfunction in cancer patients treated with immunotherapy
Purpose Immunotherapy against immune checkpoints has significantly improved survival both in metastatic and adjuvant setting in several types of cancers. Thyroid dysfunction is the most common endocrine adverse event reported. Patients who are at risk of developing thyroid dysfunction remain to be defined. We aimed to identify predictive factors for the develop- ment of thyroid dysfunction during immunotherapy.
Methods This is a retrospective study including a total of 68 patients who were treated with immune checkpoint inhibi- tors (ICIs) for metastatic or unresectable advanced cancers. The majority of patients were treated with anti-PD1 drugs in monotherapy or in combination with anti-CTLA4 inhibitors. Thyroid function and anti-thyroid antibodies, before starting immunotherapy and during treatment, were evaluated. Thyroid ultrasound was also performed in a subgroup of patients at the time of enrolment in the study.
Results Eleven out of 68 patients (16.1%) developed immune-related overt thyroid dysfunction. By ROC curve analysis, we found that a serum TSH cut-off of 1.72 mUI/l, at baseline, had a good diagnostic accuracy in identifying patients without overt thyroid dysfunction (NPV = 100%, p = 0.0029). At multivariate analysis, both TSH and positive anti-thyroid antibod- ies (ATAbs) levels, before ICIs treatment, were independently associated with the development of overt thyroid dysfunction during immunotherapy (p = 0.0001 and p = 0.009, respectively).
Conclusions Pre-treatment serum TSH and ATAbs levels may help to identify patients at high risk for primary thyroid dysfunction. Our study suggests guidance for an appropriate timely screening and for a tailored management of thyroid dysfunctions in patients treated with ICIs
Inflammatory bowel disease: an increased risk factor for recurrent laryngeal nerve palsy in thyroid surgery
Is sleeve gastrectomy a therapeutic procedure for all obese patients?
Background: Laparoscopic sleeve gastrectomy (LSG) is a worldwide surgical procedure for morbid obesity. However patients selection is still anecdotal. The aim of this study is to analyse clinical and anthropometric parameters correlated with LSG and to check the validity of this procedure for different categories of obese patients. Methods: Two-hundred one consecutive patients were submitted to LSG as a primary bariatric procedure between 2008 and 2014. One year follow-up was completed in 159 patients. Smaller groups of patients completed 2 and 3 years follow-up (78, 46 patients respectively). Median preoperative body mass index (BMI) was 45.4 kg/m2 (range: 34.8-73.8); 135 patients (80%) had one or more comorbidities. Potential correlations between age, gender, preoperative BMI, preoperative excess weight, early excess weight loss (EWL) and 1 and 3 year-EWL were investigated. Results: All procedures were regularly completed with laparoscopic approach without conversion to laparotomy. Postoperative complications occurred in six patients (3.7%); no postoperative mortality was observed. Median one-year BMI and EWL were 32.8 kg/m2 and 55.34%, respectively. Three year-EWL was significantly influenced by age, and early EWL. A complete normalization of glycemic levels after the three-year follow-up was also observed in high percentage of diabetic patients. In patients with preoperative BMI>50 kg/m2 we observed most failure cases in terms of EWL and the worst metabolic results. Conclusions: Our experience indicates that LSG is a safe procedure with satisfactory three-year late weight loss in patients with preoperative BMI <50 kg/m2. Promising results, in terms of improvements of comorbidities, were also observed. These results make LSG one of the most attractive first stage surgical procedure for morbid obesity
Management of thyroid nodules: a clinicopathological, evidence-based approach
Management of thyroid nodules is one of the
most controversial issues in thyroidology. Different approaches
derive from geographical variation in presentation,
inadequate or incomplete clinical diagnosis, lack of
prospective controlled studies and, frequently, the different
cultural backgrounds of physicians. This review aims
to offer a practical approach to the management of nodular
thyroid disorders, considering the way in which the
pathophysiology of the disease provides clues to the correct
clinical diagnosis and therapy
Effects of pravastatin treatment on vitamin D metabolites
Hyperlipidemias, and notably hypercholesterolemia, represent important risk factors for atherosclerotic vascular disease. The enzymatic inhibitors of 3-hydroxy-3-methylglutaryl coenzyme A reductase, a selective and specific key enzyme involved in endogenous cholesterol synthesis, cause a significant mean reduction in low-density lipoprotein (LDL) cholesterol, both in familial and nonfamilial hypercholesterolemic forms. It has been hypothesized that these compounds might interfere with vitamin D endogenous synthesis secondarily to their effects on cholesterol. To verify this hypothesis, we studied 14 hypercholesterolemic patients treated as follows: 4 weeks of low-lipid, fiber-rich diet followed by 8 weeks of pravastatin treatment at the oral evening dose of 20 mg/d and by a 1-month washout period. No significant changes in serum calcium, 25-hydroxyvitamin D, and 1,25-dihydroxyvitamin D were noticed; on the contrary, significant (P < 0.01) reductions in total cholesterol and LDL cholesterol and a significant (P < 0.05) increase in high-density lipoprotein cholesterol were observed. After the final 1-month washout period, all values returned to baseline levels. In conclusion, our study confirms the clinical efficacy of pravastatin on lipid fractions and demonstrates the absence of any interference on the circulating levels of the main vitamin D metabolite
