Four patients with thyrotoxicosis, hypercalcaemia and metabolic bone disease are described. One of them had a 'hot nodule', T3 toxicosis and a parathyroid tumour and another had thin bones, subperiosteal cortical bone erosions and complete dysphagia. Hypercalcaemia persisted during treatment with antithyroid drugs in two patients, both of whom had hyperparathyroidism. The administration of salmon calcitonin to these two patients before starting antithyroid treatment produced an immediate and sustained fall in serum calcium and urinary hydroxyproline levels. Calcitonin administration should be of value in the early management of hypercalcaemic patients.

Authors report the postoperative complication rate in 52 patients who had undergone total thyroidectomy for cancer between 1984 to 1989. Total thyroidectomy has been performed in 9.8% of patients surgically treated for nodular thyroid pathology. Patients age average 49 years in a range 16-75; they were 49 women and 3 men. In 50% of cases we found papillary cancer, follicular in 40%, medullary 4% and anaplastic 6%. We shared postoperative complications in two mean groups: 1) aspecific complications as cardiocirculatory failure, respiratory failure, wound infections or collections, granulomas, keloids; 2) surgery related complications such as hypocalcemia, dysphagia, recurrent++ paralyses. The first group, we noticed just one case of respiratory mechanical failure due to severe tracheomalacia that required a temporary tracheostomy performed at the end of surgical procedure; we did not notice any death due to cardio-circulatory or respiratory failure, nor did we notice any postoperative hemorrhage; one patient presented a wound seroma, two patients presented granulomas due to subcutaneous stitches, and three developed papulous drug-induced erythema. The second group, eight patients developed a transient hypocalcemia beginning on the second postoperative day, without relevant tetanic crisis, well treated by calcium administration; only two of these patients developed permanent hypoparathyroidism. In 3 cases we had to perform exeresis of a laryngeal inferior nerve involved by the cancer, while in 5 more cases we noticed a transient monolateral paralysis that disappeared in 2 or 3 months. Three patients presented dysphagia before intervention and healed post-surgery.(ABSTRACT TRUNCATED AT 250 WORDS)

In this paper the pharmacodynamic effects of calcium channel blockers (verapamil, nifedipine, diltiazem, fendiline, nitrendipine, nimodipine, and nisoldipine) on esophageal motility in man and their clinical effects in patients with various forms of primary esophageal motility disorders are critically analysed and summarized. The evaluation of efficacy and safety is mainly focused on nifedipine (Bay a 1040, Adalat; CAS 21829-25-4), since it has been best documented clinical pharmacologically and therapeutically in this field. Nifedipine and--with varying potency--the other calcium antagonists reduce effectively the increased lower esophageal sphincter pressure (LESP) and abnormally high and prolonged peristaltic and nonperistaltic contractions in the esophageal body in patients with achalasia, diffuse esophageal spasm (DES), and other disorders which may cause angina-like chest pain and/or dysphagia. Pharmacodynamic effects on esophageal motility are closely correlated with the plasma concentration of nifedipine in healthy volunteers and in patients. However, a final judgement on the therapeutic value of these compounds in esophageal motor abnormalities cannot be given due to conflicting results from clinical studies with fairly small numbers of patients and varying study designs. Among the different calcium antagonists investigated nifedipine represents the best investigated and the most suitable compound for the treatment of primary hypertensive esophageal motor disorders.

1. Neuroleptic drugs (antipsychotics) produce numerous side effects which include serious extrapyramidal symptoms consisting of akathisia, dystonia, neuroleptic malignant syndrome, parkinsonian reactions such as postural abnormality, tremor, akinesia or bradykinesia, rigidity, and tardive dyskinesia. 2. Among the complications of neuroleptic chemotherapy, the most serious and potentially fatal complication is malignant syndrome, which is characterized by extreme hyperthermia, "lead pipe" skeletal muscle rigidity causing dyspnea, dysphagia, and rhabdomyolysis, autonomic instability, fluctuating consciousness, leukocytosis, and elevated creatine phosphokinase. 3. Neuroleptic malignant syndrome should be differentiated from malignant hyperthermia, lethal catatonia, and other pathological states producing some of these same symptoms. 4. In addition to neuroleptics, malignant syndrome has been caused by thymoleptics (antidepressants), metoclopramide (antiemetic), metoclopramide combined with cimetidine, tetrabenazine, overdosage of benzodiazepine, phenelzine, dothiepin and alcohol, and amphetamine. 5. Factors leading to and/or facilitating the emergence of neuroleptic malignant syndromes are reportedly organic brain syndrome, dehydration, exhaustion, external heat load, excessive sympathetic discharge, use of long acting neuroleptics, high doses of neuroleptics, rapid dose titration with neuroleptics, abrupt discontinuation of antiparkinsonism agents, and concurrent lithium therapy. 6. Although, the pathogenesis of neuroleptic malignant syndrome is not understood completely, a blockade of dopaminergic receptors in the hypothalamus, spinal cord and striatum, an alteration of dopaminergic-serotonergic transmission in the body, an enhanced synthesis and action of prostaglandin E1 and E2, and a modification of calcium-mediated signal transduction in the body have been suggested. 7. The treatment of malignant syndrome includes immediate withdrawal of neuroleptic drugs, i.v. infusion of dantrolene, and oral administration of bromocriptine; or alternatively i.v. infusion of dantrolene and the combination of levodopa-carbidopa. 8. Other measures to enhance the therapeutic effectiveness of the aforementioned regimens are to include the use of anticholinergic drugs such as benztropine to enhance the effectiveness of bromocriptine, of lorazepam if catatonic symptoms persist, or of electroconvulsive therapy (ECT) if psychotic symptoms persist. 9. These treatments, however, must be "active" rather than "passive", in order to avert fatalities and/or unfortunate sequelae from this iatrogenic and incompletely understood disease.

Calcium channel blockers have been previously shown to decrease lower esophageal sphincter (LES) pressure and improve symptoms in achalasia. We performed a placebo-controlled, double-blind, crossover study to assess the effects of oral nifedipine and verapamil on LES pressure, amplitude of esophageal body contraction, and clinical symptomatology in eight patients with symptomatic achalasia diagnosed by endoscopy, barium swallow, and manometry. Patients were randomized to receive up to 20 mg nifedipine, 160 mg verapamil, or placebo and underwent esophageal manometry before (baseline) and after four weeks on each drug. Diary cards were kept to record and grade symptoms and drug plasma level determinations were correlated with manometric and clinical findings. Both nifedipine and verapamil caused a statistically significant decrease in mean LES pressure, but only nifedipine caused a significant decrease in the amplitude of contractions of the smooth muscle portion of the esophagus. No statistically significant differences in the overall clinical symptomatology were noted with any of the drugs, although some individual improvements in dysphagia and chest pain were noted. We conclude that, despite the reduction in LES pressure and contraction amplitude of the distal esophageal body, oral nifedipine and verapamil do not significantly alter the clinical symptomatology of patients with achalasia.

Idiopathic hypoparathyroidism was diagnosed in five young to middle-aged cats of mixed breeding. Three of the cats were male and two were female. Historic signs included lethargy (n = 5), anorexia (n = 5), muscle tremors (n = 4), weakness (n = 4), generalized seizures (n = 3), ataxia (n = 3), mental dullness or disorientation (n = 3), panting (n = 2), pruritus (n = 1), ptyalism (n = 1) and dysphagia (n = 1). Weakness (n = 4), dehydration (n = 2), cataracts (n = 2), hypothermia (n = 1), and bradycardia (n = 1) were found on physical examination. Results of electrocardiography revealed a prolonged Q-T interval in two cats. Results of initial laboratory tests revealed profound hypocalcemia and severe hyperphosphatemia with normal renal function. The diagnosis of hypoparathyroidism was made on the basis of the history, clinical signs, and results serum biochemical testing (i.e., severe hypocalcemia and hyperphosphatemia); in two cats, the diagnosis was also confirmed by histologic examination of parathyroid glands. Initial treatment included intravenous administration of 10% calcium gluconate and oral administration of large loading doses of calcium and vitamin D (dihydrotachysterol). Successful long-term management with dihydrotachysterol and calcium was achieved in all cats. The final dosage of dihydrotachysterol required to maintain normocalcemia in the five cats ranged from 0.004 to 0.04 mg/kg/day (mean = 0.015 mg/kg/day). Long-term calcium supplementation was given to three of the cats in dosages ranging from 29 to 53 mg/kg/day (mean = 42 mg/kg/day) of elemental calcium. One cat died after 28 months of therapy from widely metastatic hemangiosarcoma; the other three cats are still alive and well after 5 to 37 months of treatment.

Calcium antagonist relax smooth muscle, a possible useful concept in treatment of diffuse oesophageal spasm. Therefore the effects of oral diltiazem (60 mg t.d.s.) and placebo were compared in eight patients with diffuse oesophageal spasm in a 10-week double-blind crossover study. The patients recorded the severity of chest pain and/or dysphagia in daily pain diaries using visual analogue scales. Chest pain index and dysphagia index were calculated by multiplying frequency with daily intensity of each individual symptom. When compared to placebo, diltiazem did not significantly change the overall dysphagia index and chest pain index. An individual sizeable reduction of dysphagia was attained on diltiazem in four out of six patients and in six out of eight patients suffering from chestpain. Side effects were not seen during diltiazem therapy. Diltiazem, in our study, did not yield in a significant improvement of symptoms in diffuse oesophageal spasm. Diltiazem, however, can offer relief in selected individual patients suffering from diffuse oesophageal spasm.

Clinical symptoms and signs and the frequency of abnormalities in the results of enzymatic, electromyographic, histological and serological tests were analysed in 50 patients, including 17 with polymyositis (PM) and 33 with dermatomyositis (DM), groups I and II according to Bohan's classification and followed-up for 25 years. Weakness of the proximal muscles of the extremities was present in both groups in all patients and in a high proportion of cases weakness involved also the distal muscles. Dysphagia was more frequent in DM patients (54.5%) than in PM (17.6%). In DM erythema and facial oedema as well as Gottron's sign were observed more frequently. In 11.8% of PM patients and 15.1% of DM patients deposition of calcium salts in subcutaneous tissue developed. Signs of vasculitis were found in 39.4% of DM cases and 17.6% of PM cases. In one-third of PM and in only 3 DM cases pitting oedema of the distal parts of the extremities was noted. Cardiovascular changes were disclosed in 82.3% of PM and 69.7% of DM patients. On the other hand, radiological signs of interstitial pulmonary fibrosis were noted more frequently in DM (36%) than in PM (23%). Increased serum activity of CPK, AspAT and ALAT was present with similar frequency in both groups from 71% to 81% of cases. EMG showed evidence of primary muscular changes in all PM patients and 69.6% of DM patients. Histological examination confirmed the diagnosis in the studied patients. Antinuclear antibodies were found relatively rarely, from 2% to 24% of PM/DM patients.(ABSTRACT TRUNCATED AT 250 WORDS)

Although fistulae and hypercalcemia are rare at the time of diagnosis of esophageal carcinoma, they are not uncommon terminal events. Most fistulae communicate with the respiratory tract. Uncommon sites of fistulae due to esophageal carcinoma include extension to the aorta, pleura, pericardium, and mediastinum. We report a patient with a spontaneous pneumomediastinum discovered during radiologic staging of esophageal carcinoma. The symptoms were dysphagia, weight loss, and pneumonia. The patient had hypercalcemia refractory to conventional measures, another adverse prognostic factor. Cisplatin 100 mg/m2 was tolerated without acute toxicity and lowered the serum calcium to normal. However, the patient died due to respiratory failure 2 days after cisplatin therapy. To our knowledge, this is the first report of a spontaneous pneumomediastinum at presentation of an esophageal carcinoma. The course of our patient and a review of the literature suggest that fistulae and/or hypercalcemia are medical emergencies and are often fatal in esophageal carcinoma.

A patient with long-standing, asymptomatic, primary hyperparathyroidism developed pain in the anterior neck area, with cough, dysphagia and increasing shortness of breath. This led to respiratory insufficiency, which required endotracheal intubation and respirator assistance. During the ensuing hours the patient developed an area of ecchymosis on the anterior chest. Chest x-ray showed widening of the superior mediastinum, and CT scan showed a large mass with a fluid level. Surgery revealed a large hematoma originating from a mediastinal parathyroid adenoma with a hemorrhagic infarct. Serum calcium, previously elevated, decreased to normal with the onset of neck pain, and the patient remains normocalcemic. Previous reported cases of this rare complication of parathyroid adenomas are reviewed. Hemorrhagic infarct of a parathyroid adenoma may present with a rapidly enlarging mediastinal mass, and/or hypercalcemic crisis. Surgical removal of the infarcted adenoma can return the serum calcium to normal.
