A main goal to achieve in order to reduce the incidence of wrong nutritional habit associated diseases, according to the engagement taken on the FAO/WHO International Conference on Nutrition 1992 is the eradication of the endemic goitre and other iodine deficiency disorders. Iodine nutritional lack is, in Italy, a heavy public health problem; above 10% of population (about 5 million) has to bear thyroid troubles and in many of the Italian regions such a kind of pathology may involve more than 20% of scholastic population. All these disorders could be completely eradicated by means of a continuous and generalized iodine prophylaxis, as it has already been verified in several European countries. The most effective way to ensure the correct daily intake of iodine is the substitution of the usual cooking salt by iodine enriched salt; salt is in fact eaten by everybody at daily rates ungoverned by economical factors as it is a low cost product. Due to the heavy social relevance of this problem, an educational campaign is going on, from the Italian Ministry of Health "Salt in food for iodine deficiency disorder prophylaxis and hypertension prevention". The purpose is to achieve, by means of a unique message based on salt, a double goal in terms of public health: eradicating endemic goitre and preventing hypertension (reducing the salt global intake to less than 6 g/day).

The objective of the study was to investigate the efficacy of long term thyrostatic versus radioiodine treatment of hyperthyroidism in old age. Our study is a retrospective analysis of the therapeutical outcome in 66 patients over 60 years of age with toxic nodular goitre. The patients were divided in two groups: Group A: 28 patients on methimazole treatment: starting dose 5-30, median (M) 10 mg, maintenance dose 2.5-15 (M = 5) mg, follow up 6 to 240 months (M = 23.5 months). Group B: 38 patients treated by either 100-300 MBq (N = 14, subgroup B1) or 325-1000 MBq (N = 24, subgroup B2) 131I, follow up: 18 to 156 months (M = 48 months). The efficacy of the different therapeutical approaches were compared by calculating the occurrence rate of persisting and relapsing thyroid dysfunctions and associated side effects. The 28 patients on methimazole treatment became euthyroid after 1-16 (M = 5) months but numerous relapses occurred in the follow up: hyperthyroidism, clinical: 5, subclinical 13, (relapse duration: M = 8 months; associated symptoms: hypertension in 4, cardiac arrhythmia in 3, cerebral embolism in 1, angina pectoris in 2, weight loss in 2 cases). Poor patient's compliance (9/28) or dose reduction by the physician (5/28) were the main causes of the relapses. Transient clinical (3 cases) or subclinical (6 cases) hypothyroidism also occurred (duration: 1-3 M = 2 months, no clinical symptoms). In 7 out of 14 (50%) patients receiving 100-300 MBq 131I (Group B1) hyperthyroidism persisted (versus 4/24 -16.7%- in Group B2 following 325-1000 MBq 131I; chi2(1) = 4.78 P = 0.028), methimazole treatment had to be continued in 9/14 patients (64.3%) (versus 5/24 -20.8%)- in Group B2., chi2(1) = 7.18 P = 0.0074) and in 5/14 (35.7%) the radiotherapy had to be repeated (versus 5/24 -020.8%- in Group B2, not sign.). Our conclusions are: 1) long term thyrostatic treatment is not safe in elderly patients with toxic nodular hyperthyroidism, mainly because of poor compliance or dose reduction by the physician; 2) radioiodine treatment as the first choice should be recommended for these patients and higher doses should be preferred.

Dietitians are multifunctional and play an important role in humanitarian missions as educators, planners, and consultants. Three dietitians deployed to Thailand in support of the 16th Annual Joint and Combined Exercise, Cobra Gold 1997. The goal of the Medical Civic Assistance Program (MEDCAP) was to promote long-term public health improvements in rural Thai villages. The dietitians counseled 140 patients and taught an additional 5,300 individuals during nutrition classes. The primary nutrition-related clinical diagnoses included malnutrition, anemia, diabetes, hypertension, goiter, and poor appetite. The dietitian who deployed as the medical planner and MEDCAP executive officer facilitated coordination and planning for all phases of the MEDCAP operation. The teams were made up of U.S. and Thai military forces and Thai civilian medical personnel. The mission requirements were established with the Royal Thai Supreme Command, Thai governors, Ministry of Public Health officers, military and medical officers, and veterinarians of the three provinces.

Hormone-secreting pituitary microadenomas are often not visible on magnetic resonance imaging (MRI). Diagnosis requires confirmatory endocrine test results and often an invasive procedure, inferior petrosal sinus sampling (IPSS). Improved pituitary imaging may eliminate the need for IPSS in some patients, as shown in the 2 women in this report. The first patient with hirsutism, weight gain, and hypertension had intermittent elevations of urinary free cortisol, abnormal results on a low-dose dexamethasone suppression test, and positive results on a dexamethasone-suppressed ovine corticotropin-releasing hormone test (corticotropin, increase of 122%; cortisol, increase of 118%). Gadolinium-enhanced MRI showed no focal lesion, but dynamic MRI (sequential images beginning immediately after contrast injection) revealed a right-sided 5-mm microadenoma, confirmed by transsphenoidal surgery. The second patient had a goiter, anxiety, increased free thyroxine and triiodothyronine levels, and a normal thyrotropin value with no response to thyrotropin-releasing hormone. Magnetic resonance imaging showed no lesion, but dynamic MRI detected an 8-mm microadenoma. Although about 8% to 10% of healthy persons have incidental pituitary lesions that are 3 mm or larger on MRI, identification of a distinct lesion and positive results on a dexamethasone-suppressed ovine corticotropin-releasing hormone test should decrease the probability of a false-positive result on an imaging study. We recommend that dynamic MRI be performed in any patient with a suspected microadenoma, before IPSS is performed.

In our clinic 19615 patients were operated over 25 years on for goiter. Malignant thyroid neoplasms were found in 1049 (5.3%) patients including 875 (83.4%) women and 174 (16.6%) men. Sixty two adult patients (42 women and 20 men were operated on for medullary thyroid carcinoma (MTC). Thyroid cancer was diagnosed in this group pre or intraoperatively in 44 (71%) patients and postoperatively, on histologic examination, in 18 (29%) patients. These patients were reoperated. Radical operations (total thyroidectomy with regional lymph node removal) were conducted in 43 (69.3%) patients and palliative ones in 19 (30.7%) patients. After MTC surgery, MEN 2A (MTC and an adrenal tumor) were diagnosed by means of imaging techniques (USG, CT) in 6 (9.7%) patients. All adrenal tumors were unilateral. Five of these patients were operated, and pheochromocytoma was confirmed by histopathologic examination. Two years after the MTC operation, 1 women was lost to follow-up. After a year, she was admitted to hospital for severe hypertension and died of cerebral hemorrhagia. Pheochromocytoma was revealed by autopsy. All patients were treated complementarily after the MTC operation. Different combinations of teleradiotherapy, chemotherapy and substitutive doses of levothyroxine were used. Ten (23.2%) of 43 patients operated radically were reoperated 1-3 years after the first operation due to loco-regional tumor recurrence. Radical reoperations were performed in 4 patients, and palliative ones in 6. Over a 0.5-23-year follow-up period, 26 (41.9%) patients died, including 20 of cancer, and 6 of other reasons. Four out of 36 living patients have clinical or biochemical symptoms of neoplastic disease. The follow-up period of MEN 2 patients operated on ranged from 1 to 6 years. Up to now, no tumor in the second adrenal gland has been diagnosed in any of these patients. Genetic (molecular) tests performed in 31 out of 36 living patients revealed mutations of RET gene in 4 (12.9%).

A 67-year-old woman with hypertension, diabetes, hypothyroidism and chronic renal failure reported to the hospital for her regularly scheduled hemodialysis, complaining of shortness of breath. Despite fluid removal during her hemodialysis, she remained tachypneic and developed stridor. She was admitted to the hospital for a work-up of a known mediastinal mass, thought to be a goiter. However, she deteriorated over the next several hours and expired. A post-mortem examination confirmed fatal pulmonary emboli. This case illustrates the fact that, while most patients with chronic renal failure are considered to be at low risk for pulmonary emboli, it is often not diagnosed when present. In this paper, we will review the epidemiological data supporting this notion, examine proposed pathophysiological mechanisms, and review the diagnostic approach that should be considered in the setting of chronic renal failure.

In a prospective randomized study the hypothesis was tested whether infiltration of the thyroid capsule by a local anaesthetic will reduce the haemodynamic response to surgical trauma, consumption of anaesthetics and opioids during surgery and will shorten the time of arousal. A total of 64 patients indicated for planned goitre surgery were divided at random into a control group (C, n = 32) and experimental group (LA, n = 32). The preoperative medication and anesthesia did not differ in the two groups. In group C into the thyroid capsule a maximum of 40 ml saline was administered, in LA the same volume of 0.5% trimecain. A highly significant difference was found (p < 0.001) in the incidence of hypertension during surgery (21 C vs. 5 LA) and the need of further pharmacological interventions (21 vs. 8). In the control group was a higher consumption (p < 0.95) of the opioid phentanyl (167.5 +/- 111 micrograms vs. 125 +/- 93.5 micrograms), a trend of longer arousal and the need to antagonize the effect of opioid (p < 0.1). The substitution of saline by a local anaesthetic for infiltration of the thyroid capsule is a safe and simple method leading to a reduction of cardiovascular complications during surgery.

In this cross-sectional study, 8,481 women aged 15-49 who had at least one pregnancy outcome were considered. This study aimed to examine the characteristics of Filipino women having had a pregnancy loss, and to test the association between domestic violence and pregnancy loss. To control for the confounding effect of the number of pregnancies, the sample was divided into seven groups classified by the number of pregnancies. The risk factors considered were demographic characters (age and partner's age, marital status, and place of residence), socioeconomic status (education and partner's education, having a paid helper at home, having a say in how income was spent), domestic violence (physical abuse and forced sex), sexual behavior of partner, whether the pregnancy was wanted, and disease history (tuberculosis, diabetes, hypertension, malaria, hepatitis, kidney disease, heart disease, anemia, goiter and other medical problems). The major risk factors were found to be physical abuse, region, faithfulness of partners, hypertension, hepatitis, kidney disease, anemia, and the other medical problems, respectively. The risk of pregnancy loss for the women suffering domestic violence was 1.59 (95% CI 1.28-1.97) times higher than for the women who did not. Women aged 15-19 years had a much higher risk of pregnancy loss than the other age groups (OR = 1.49, 95% CI 1.22-1.82). There were similar risk for women aged 20-24 years (OR = 1.08, 95% CI 0.94-1.25) and 35-39 years (OR = 1.05, 95% CI 0.92-1.19). No association emerged with marital status, socioeconomic status, forced sex, the number of partners, unwanted pregnancy, tuberculosis, diabetes, malaria, heart disease, and goiter. Although women's age, partner's age, residence, women's education, partner's education, and paid helper at home were significantly associated with pregnancy loss, they were likely to be confounders rather than risk factors.

The study was performed to evaluate the prevalence of thyroid abnormalities detected by ultrasonography and, in particular, of multinodular nontoxic goiter in primary aldosteronism. We analyzed 80 consecutive of patients with primary hyperaldosteronism (40 with unilateral adenoma and 40 with idiopathic hyperaldosteronism) and 80 normotensive healthy controls, comparable for age, sex, iodine intake, and geographical area. Blood pressure, thyroid palpation, thyroid function, and ultrasonography were evaluated. The prevalence of ultrasonographic thyroid abnormalities was 60% in primary aldosteronism and 27% in controls (p < 0.0001). There was a statistically significant difference in prevalence of these abnormalities in unilateral adenoma and idiopathic hyperaldosteronism with respect to controls (p < 0.05 and p < 0.0001, respectively). The prevalence of multinodular nontoxic goiter in idiopathic hyperaldosteronism was higher than in controls (p < 0.001) and, in particular, in female patients. From these data it seems to be worth considering the existence of primary hyperaldosteronism in patients with multinodular goiter and hypertension.
