The thyroid disorders are one of the most common and exciting areas of endocrinology. 
Hypothyroidism, multinodular goiter, hyperthyroidism and thyroid cancer are only few of the several implications that the thyroid disorders have in health. In fact, thyroid hormones regulate not only metabolism process, but also many other molecular and physiological systems. From this point of view, hyperthyroidism complications are a good example of the significance of thyroid hormone actions. This book aims to provide a general view of thyroid disorders, and a deeper explanation of hyperthyroidism and its complications and impact in health.

Hypothyroidism is the most common thyroid disorder. 
It can cause a variety of changes in women's menstrual periods, reduce their chances of becoming pregnant, as well as affect both the course of pregnancy and the neuropsychological development of babies. During pregnancy there is a substantially increased need for thyroid hormones and a substantial risk that a previously unnoticed, subclinical or latent hypothyroidism will turn into overt hypothyroidism. The thyroid inflammation caused by the patient's own immune system may form autoimmune thyroiditis (Hashimoto's thyroiditis). Congenital hypothyroidism (CH) occurs in approximately 1:2,000 to 1:4,000 newborns. Nearly all of the developed world countries currently practice newborn screening to detect and treat congenital hypothyroidism in the first weeks of life. "A New Look at Hypothyroidism" contains many important specifications and innovations for endocrine practice.

Espectro y prevalencia de trastornos tiroideos en pacientes ingresados en la clínica de anestesiología para cirugía ambulatoria
Spectrum and Prevalence of Thyroid Disorders in Patients Admitted to the Anaesthesiology Outpatient Clinic for Surgery.
Abstract
Turk J Anaesthesiol Reanim. 2015 Aug;43(4):240-5. doi: 10.5152/TJAR.2015.03206. Epub 2015 Mar 3.
OBJECTIVE: An anaesthetic approach and surgery are important treatment strategies in patients with thyroid dysfunction due to potential complications. We investigated the prevalence of thyroid disorders, the significance of thyroid function tests (TFTs) with respect to anaesthesia in the preoperative period and the need for routine examinations. METHODS: A total of 10,600 patients who were admitted to the anaesthesiology outpatient clinic for surgery were retrospectively screened and enrolled between 2011 and 2013. Evident hypothyroidism was defined as free tetra-iodothyronine (fT4) <0.7 ng dL(-1) and thyroid-stimulating hormone (TSH) >4 mIU mL(-1), and subclinical hypothyroidism was defined as TSH >4 mIU mL(-1) with normal free hormone levels. Evident hyperthyroidism was defined as fT4 >1.7 ng dL(-1) and TSH <0.1 mIU mL(-1), and subclinical hyperthyroidism was defined as TSH <0.1 mIU mL(-1) with normal free hormone levels. Statistical analysis was conducted using the Statistical Package for the Social Sciences (SPSS) version 17.0. Independent samples t-test and one-way analysis of variance were used to compare the difference between groups. RESULTS: Of the participants, 8.5% were found to have hypothyroidism, 2.5% had hyperthyroidism, 3.5% received treatment and 2.5% had their treatment postponed. The likelihood of hypothyroidism was greater among females, and no difference was found between genders with respect to hyperthyroidism. CONCLUSION:
We believe that TFTs are important because of regional factors. However, given the high cost of TFTs and because thyroid dysfunction risk increases with age, we concluded that routine TFTs in young patients with normal physical examination findings are not mandatory.

Abstract
Hyperthyroidism is a common disease of the endocrine system and it is known that additional propofol anaesthesia is required during surgery for patients with hyperthyroidism compared with those with normal thyroid function. The aim of the present study was to determine the mechanism through which thyroid hormones (THs) inhibit the effect of propofol anaesthesia. Immunofluorescence techniques were used to verify the difference between the expression quantities of γ-aminobutyric acid type A (GABAA) receptor subunits α2 and β2 in the dorsal root ganglions (DRGs) of rats with hyperthyroidism and those in normal rats. Perforated patch clamp recordings in the whole-cell mode were performed to detect the GABA-activated current in acutely isolated rat DRG neurons from rats with hyperthyroidism and normal rats. This method was also used to evaluate the change in the GABA-activated currents following the pre-perfusion of propofol with and without 3,3',5-L-triiodothyronine (T3). Compared with normal rats, rats with hyperthyroidism expressed same quantities of GABAA receptor α2 and β2 subunits in DRGs. In addition, no difference in GABA-activated currents in the acutely isolated DRG neurons from the two types of rat was observed (P>0.05). T3 inhibits or minimises the augmentation effect of propofol on the GABA-activated currents (P<0.05). The inhibitory effect of T3 on propofol was minimised by increasing the propofol concentration (P<0.05). The inhibitory effect of T3 on the anaesthetic effect of propofol is achieved through the inhibition of the function of GABAA receptors through the non-genomic actions of the THs, rather than by changing the number of GABAA receptors. This inhibitory effect can be mitigated by increasing the propofol concentration. In conclusion, rats with hyperthyroidism require a larger dose of propofol to induce anaesthesia since the non-genomic actions of THs suppress GABA receptors, which in turn inhibits the anaesthetic action of propofol.

La tiroidectomía total como método de elección en el tratamiento de la enfermedad de Graves - análisis de 1432 pacientes.
Total thyroidectomy as a method of choice in the treatment of Graves' disease - analysis of 1432 patients.
BMC Surg. 2015 Apr 9;15:39. doi: 10.1186/s12893-015-0023-3.
Abstract
BACKGROUND: Graves' disease represents an autoimmune disease of the thyroid gland where surgery has an important role in its treatment. The aim of our paper was to analyze the results of surgical treatment, the frequency of microcarcinoma and carcinoma, as well as to compare surgical complications in relation to the various types of operations performed for Graves' disease. METHODS: We analysed 1432 patients (221 male and 1211 female) who underwent surgery for Graves' disease at the Centre for Endocrine Surgery in Belgrade during 15 years (1996-2010). Average age was 34.8 years. Frequency of surgical complications within the groups was analyzed with nonparametric Fisher's test. RESULTS: Total thyroidectomy (TT) was performed in 974 (68%) patients, and Dunhill operation (D) in 221 (15.4). Carcinoma of thyroid gland was found in 146 patients (10.2%), of which 129 (9%) were a microcarcinoma. Complication rates were higher in the TT group, where there were 31 (3.2%) patients with permanent hypoparathyroidism, 9 (0.9%) patients with unilateral recurrent nerve paralysis and 10 (1.0%) patients with postoperative bleeding. Combined complications, such as permanent hypoparathyroidism with bleeding were more common in the D group where there were 2 patients (0,9%), while unilateral recurrent nerve paralysis with bleeding was more common in the TT group where there were 3 cases (0,3%). CONCLUSIONS: Frequency of complications were not significantly statistically different in relation to the type of surgical procedure. Total thyroidectomy represents a safe and efficient method for treating patients with Graves' disease, and it is not followed by a greater frequency of complications in relation to less extensive procedures.
 Anestesia y cirugía tiroidea: los interminables desafíos.
Anesthesia and thyroid surgery: The never ending challenges.
Indian J Endocrinol Metab. 2013 Mar;17(2):228-34. doi: 10.4103/2230-8210.109671.
Abstract
Thyroidectomy is the most common endocrine surgical procedure being carried out throughout the world. Besides, many patients who have deranged thyroid physiology, namely hyperthyroidism and hypothyroidism, have to undergo various elective and emergency surgical procedures at some stage of their life. The attending anesthesiologist has to face numerous daunting tasks while administering anesthesia to such patients. The challenging scenarios can be encountered at any stage, be it preoperative, intra-op or postoperative period. Preoperatively, deranged thyroid physiology warrants optimal preparation, while anticipated difficult airway due to enlarged thyroid gland further adds to the anesthetic challenges. Cardiac complications are equally challenging as also the presence of various co-morbidities which make the task of anesthesiologist extremely difficult. Thyroid storm can occur during intra-op and post-op period in inadequately prepared surgical patients. Postoperatively, numerous complications can develop that include hemorrhage, laryngeal edema, nerve palsies, tracheomalacia, hypocalcemic tetany, pneumothorax, etc., The present review aims at an in-depth analysis of potential risk factors and challenges during administration of anesthesia and possible complications in patients with thyroid disease.

Anestesia para timectomia en un paciente con miastenia gravis e hipertiroidismo no controlado
Anesthetic management of patient with myasthenia gravis and uncontrolled hyperthyroidism for thymectomy.
Ann Card Anaesth. 2010 Jan-Apr;13(1):49-52. doi: 10.4103/0971-9784.58835.Abstract
The relationship between myasthenia gravis (MG) and other autoimmune disorders like hyperthyroidism is well known. It may manifest earlier, concurrently or after the appearance of MG. The effect of treatment of hyperthyroidism on the control of MG is variable. There may be resolution or conversely, deterioration of the symptoms also. We present a patient who was diagnosed to be hyperthyroid two and half years before the appearance of myasthenic symptoms. Pharmacotherapy for three months neither improved the myasthenic symptoms nor the thyroid function tests. Thymectomy resulted in control of MG as well as hyperthyroidism. In conclusion, effective control of hyperthyroidism in the presence of MG may be difficult. The authors opine that careful peri-operative management of thymectomy is possible in a hyperthyroid state.
