Subtotal thyroidectomy was performed for hyperthyroidism on 130 patients; 95 treated before surgery with propranolol (Group I) and 35 given only metoprolol before surgery (Group II). These patient groups were compared with reference to preoperative medication, operative and immediate postoperative course, and late results with follow-up for one to five years. Clinical response was 100% in group II and 94.7% in group I. The median length of preoperative treatment was 7.96 +/- 1.84 days in group I and 6.25 +/- 1.73 days in group II (P less than 0.05). There were no serious adverse effects of the drugs in either treatment group. No anaesthesiologic or cardiovascular complication occurred during operation in either group. Ten patients in group I (10.5%) and six patients in group II (11.4%) observed hyperthyroid manifestations in the immediate postoperative period, eliminated by the administration of the propranolol/metoprolol, and no case of thyroid storm occurred. One patient in group II developed clinical hypocalcaemia. Two patients, one in each group, presented temporary unilateral recurrent laryngeal nerve paralysis. There were two recurrences of toxicity in group I (2.1%) and none in group II. Hypothyroidism occurred in 3 patients (2.3%) two of them were from group I and one was from group II. The postoperative hospital stay was 4.62 +/- 1.61 days in group I and 2.81 +/- 1.32 days in group II (P less than 0.05). One patient from group I died on the third postoperative day due to pulmonary oedema. The results suggest that metoprolol can be safely used and offers the advantages of desired clinical response, shorter preoperative preparation time, simplicity of dosage and shorter postoperative hospital stay in comparison to propranolol for preoperative treatment of hyperthyroidism.

In summary, there are a number of important respiratory manifestations of endocrine diseases. Hypothyroidism may be associated with respiratory failure that can be caused by a reduction in central respiratory drive, upper airway obstruction, and associated restrictive pulmonary function from pleural effusions or an intrinsic decrease in lung volumes. Hyperthyroidism can present with dyspnea as a major clinical manifestation because of the increase in central respiratory drive associated with thyrotoxicosis. Cardiac dysfunction associated with hyperthyroidism may lead to pulmonary edema in some patients. Hypoparathyroidism may occur acutely, especially after thyroid surgery and be associated with hypocalcemia and acute tetany, laryngeal stridor, and muscle weakness. Ovarian tumors, both benign and malignant, may present with unilateral or bilateral effusions. Finally, patients with diabetes mellitus are at increased risk of developing a variety of pulmonary disorders. Acute and chronic pulmonary infections are the most common respiratory abnormalities in patients with diabetes, although cardiogenic and noncardiogenic pulmonary edema can also be a complication of their disease.

A 53-year-old female, who had been severe hypothyroidism for about ten years, was admitted Stanford type A acute aortic dissection. The replacement of ascending aorta with a composite graft and coronary artery bypass grafting were performed immediately. During the post operative period, many complications occurred including delayed awakening from anesthesia, paralytic ileus, colon perforation, hyperbilirubinemia, pulmonary edema, cerebral hemorrhage and bacterial endocarditis. In this case, intravenous administration of steroid and thyroid hormone was effective to keep hormone level in the normal range although enteral administration was ineffective. It was suggested that early active supplement therapy is mandatory to prevent postoperative complications.

Thyrotoxic or hyperthyroid storm is a grave, life-threatening, but relatively infrequent medical emergency. Immediate causes of death in this emergency are severe hyperpyrexia and pulmonary edema associated with arrhythmias, shock, and coma. This emergency is found in Graves' patients most frequently. Myxedema coma is an emergency clinical state caused by severe deficiency of thyroid hormones. This crisis represents the extreme expression of hypothyroidism. While it is quite useful to elicit a history of previous hypothyroidism, thyroid surgery, or radioactive iodine treatment, it is not obtainable.

Despite being banned in many countries and having its use severely restricted in others, pentachlorophenol (PCP) remains an important pesticide from a toxicological perspective. It is a stable and persistent compound. In humans it is readily absorbed by ingestion and inhalation but is less well absorbed dermally. Its distribution is limited, its metabolism extensive and it is eliminated only slowly. Assessment of the toxicity of PCP is confounded by the presence of contaminants known to cause effects identical to those attributed to PCP. However, severe exposure by any route may result in an acute and occasionally fatal illness that bears all the hallmarks of being mediated by uncoupling of oxidative phosphorylation. Tachycardia, tachypnoea, sweating, altered consciousness, hyperthermia, convulsions and early onset of marked rigor (if death occurs) are the most notable features. Pulmonary oedema, intravascular haemolysis, pancreatitis, jaundice and acute renal failure have been reported. There is no antidote and no adequate data to support the use of repeat-dose oral cholestyramine, forced diuresis or urine alkalinisation as effective methods of enhancing PCP elimination in poisoned humans. Supportive care and vigorous management of hyperthermia should produce a satisfactory outcome. Chronic occupational exposure to PCP may produce a syndrome similar to acute systemic poisoning, together with conjunctivitis and irritation of the upper respiratory and oral mucosae. Long-term exposure has also been reported to result in chronic fatigue or neuropsychiatric features in combination with skin infections (including chloracne), chronic respiratory symptoms, neuralgic pains in the legs, and impaired fertility and hypothyroidism secondary to endocrine disruption. PCP is a weak mutagen but the available data for humans are insufficient to classify it more strongly than as a probable carcinogen.

The prevalence and significance of sleep-disordered breathing (SDB) in dialysis-independent chronic renal failure (CRF) remains unknown. We studied the presence of SDB in nondialyzed CRF patients. Diagnostic polysomnography was performed in consecutive stable nondialyzed CRF patients. Inclusion criteria were age <or=70 years, absence of systolic dysfunction or history of pulmonary edema, FEV(1) > 70% pr, absence of neurologic disease or hypothyroidism, and calculated creatinine clearance <40 ml/min. Thirty-five patients (19 male, 16 female) were studied. An apnea-hypopnea index (AHI) >or=5/h was present in 54.3% (almost exclusively obstructive events). AHI correlated with urea (r = 0.35, p = 0.037), age (r = 0.379, p = 0.025), and body mass index (BMI) (r = 0.351, p = 0.038), but not with creatinine clearance. AHI or SDB were unrelated to gender. In nondiabetics (n = 25), AHI correlated with urea (r = 0.608, p = 0.001) and creatinine clearance (r = -0.50, p = 0.012). Nondiabetics with severe CRF (calculated GFR < 15 ml/min/1.73 m(2)) had a significantly higher AHI compared with less severe CRF. Restless legs syndrome (RLS) was present in 37.1% and periodic limb movements in 28.6%. Daytime sleepiness was not associated with respiratory events, but was more common in patients with RLS. The prevalence of SDB and RLS is high in dialysis-independent CRF. SDB weakly correlates with indices of kidney function and this association becomes stronger in nondiabetics.

Idiopathic retroperitoneal fibrosis (IRF) is a rare disease of unknown origin, characterised by an inflammatory proliferative fibrosing process occurring in the retroperitoneum. Hashimoto's thyroiditis (HT) is a form of chronic thyroiditis that in some cases shows an extensive replacement of thyroid parenchyma by fibrous tissue. We report the rare association of IRF with HT in a 68-year-old woman presenting with pulmonary oedema, acute renal failure due to bilateral hydronephrosis and a firm diffuse goitre with hypothyroidism. The so far reported cases of IRF associated with chronic thyroiditis are reviewed, and the possible aetiopathogenetic link between these two entities is discussed.

A 24-year-old adult with a Down syndrome was admitted in December 2006 at the Moutiers hospital in the French Alps for an acute inaugural episode of high altitude pulmonary edema (HAPE) that occurred in the early morning of day 3 after his arrival to La Plagne (2000 m). This patient presented an interventricular septal defect operated on at the age of 7, a hypothyroidism controlled by 50 microg levothyrox, a state of obesity (BMI 37.8 kg/m(2)), and obstructive sleep apneas with a mean of 42 obstructive apneas or hypopneas per hour, treated with continuous positive airway pressure (CPAP). The patient refused to use his CPAP during his stay in La Plagne. At echocardiography, resting parameters were normal, with a left ventricular, ejection fraction of 60%, a normokinetic right ventricle, and an estimated systolic pulmonary artery pressure (sPAP) of 30 mmHg. At exercise, sPAP rose to 45 mmHg and the right ventricle was still normokinetic and not dilated. An exercise hypoxic tolerance test performed at 60 W and at the equivalent altitude of 3300 m revealed a severe drop in arterial oxygen saturation down to 60%, with an abnormal low ventilatory response to hypoxia, suggesting a defect in peripheral chemosensitivity to hypoxia. In conclusion, patients with Down syndrome, including adults with no cardiac dysfunction and regular physical activity, are at risk of HAPE even at moderate altitude when they suffer from obstructive sleep apneas associated with obesity and low chemoresponsiveness. This observation might be of importance since an increasing number of young adults with Down syndrome participate in recreational or sport activities, including skiing and mountaineering.

A 5 yr old intact female cocker spaniel dog weighing 7.8 kg was referred with anorexia, vomiting, and depression. At referral, the dog was diagnosed initially with typical hypoadrenocorticism, and 2 d later, concurrent primary hypothyroidism was detected. Hormonal replacement therapies, including fludrocortisone, prednisolone, and levothyroxine, were initiated, but a few days later the dog became abruptly tachypneic, and thoracic radiographs indicated the development of pulmonary edema. Echocardiography showed that there were abnormalities indicating impaired left ventricular function, although the heart valves were normal. Following treatment with pimobendan and furosemide, the pulmonary edema resolved. The dog had no recurrence of the clinical signs after 10 mo of follow-up, despite being off all cardiac medications; consequently, the cardiac failure was transient or reversible in this dog. The case report describes the stepwise diagnosis and successful treatment of cardiogenic pulmonary edema after initiation of hormonal replacement therapy for concurrent hypoadrenocorticism and hypothyroidism in a dog.

Most patients with hypertension have no clear etiology and are classified as having primary hypertension. However, 5% to 10% of these patients may have secondary hypertension, which indicates an underlying and potentially reversible cause. The prevalence and potential etiologies of secondary hypertension vary by age. The most common causes in children are renal parenchymal disease and coarctation of the aorta. In adults 65 years and older, atherosclerotic renal artery stenosis, renal failure, and hypothyroidism are common causes. Secondary hypertension should be considered in the presence of suggestive symptoms and signs, such as severe or resistant hypertension, age of onset younger than 30 years (especially before puberty), malignant or accelerated hypertension, and an acute rise in blood pressure from previously stable readings. Additionally, renovascular hypertension should be considered in patients with an increase in serum creatinine of at least 50% occurring within one week of initiating angiotensin-converting enzyme inhibitor or angiotensin receptor blocker therapy; severe hypertension and a unilateral smaller kidney or difference in kidney size greater than 1.5 cm; or recurrent flash pulmonary edema. Other underlying causes of secondary hypertension include hyperaldosteronism, obstructive sleep apnea, pheochromocytoma, Cushing syndrome, thyroid disease, coarctation of the aorta, and use of certain medications.
