[Surgical treatment of hormone-producing pituitary adenomas].

BACKGROUND: Transsphenoidal surgical treatment is established as a treatment of hormonally active pituitary tumours, except prolactinomas. The cure rates in studies of large series of patients are varying. The volume of patients at Haukeland University Hospital, Bergen is limited, and in order to maintain sufficient experience, one surgeon performs all procedures. The aim of this study was to study the rates of cure and complications in patients who had undergone this procedure. METHODS: We did a retrospective survey evaluating the operative results of one surgeon operating hormonally active pituitary tumours from 1993 through 2002 at Haukeland University Hospital. Data were collected from medical and surgical case records. RESULTS: Primary surgery cured 37 out of 57 patients. There were 13 complications, including one death in hospital. Twenty patients received additional treatment with surgery, radiation therapy, or adrenalectomy. Thirteen of these patients received medical treatment with either somatostatin analogues or dopamine agonists. INTERPRETATION: Our study indicates that one surgeon can achieve results for transsphenoidal surgery that are on par with results reported from larger centres.

[Endogenous Cushing's syndrome].

BACKGROUND: Untreated endogenous Cushing's syndrome is a serious condition with high morbidity and mortality. New diagnostic procedures make today's assessment more accurate. We describe which tests should be done when there is suspicion of the syndrome. Treatment options are mentioned. MATERIAL AND METHODS: The paper is based on current international literature and reflects the experience of the authors. RESULTS AND INTERPRETATION: Endogenous Cushing's syndrome is caused by elevated cortisol levels. The reason can be overproduction of ACTH or an adrenocortical pathology. It should be considered when combinations of symptoms like central obesity, proximal muscle weakness, striae and menstrual irregularities are seen. Osteoporosis and impotence are other important symptoms. Diagnosis of Cushing's syndrome is often challenging. Measurement of urinary free cortisol or overnight dexamethasone suppression test has usually been performed initially. Midnight salivary cortisol seems promising as an alternative. The final diagnosis is often made after a combined evaluation of dynamic tests. The first-line treatment of endogenous Cushing's syndrome is surgery.

[Hormonally inactive pituitary adenomas].

BACKGROUND: This paper surveys hormonally inactive pituitary tumours on the basis of the current international literature; it also reflects the experience of the authors. INTERPRETATION: Pituitary tumours are frequently diagnosed and usually show a low potential for growth. Although benign they may invade adjacent structures such as the cavernous and sphenoid sinuses. The diagnosis is usually made on the basis of pituitary failure or visual problems, or incidentally. Tumour debulking or removal, usually by transsphenoidal surgery, is indicated if there is a compression of the optic chiasm or if the tumour shows signs of growth on consecutive MRI scans. Surgery is an effective treatment of these tumours, with little risk of complications. Repeated surgery, either transsphenoidally or by craniotomy, is indicated if chiasmal decompression is not achieved initially. Fractionated single beam irradiation or stereotactic radiosurgery is indicated in cases where there is a residual of growing tumours that may not be removed surgically.

[Thyrotoxic periodic paralysis--an unusual complication of hyperthyroidism].

BACKGROUND: Thyrotoxic periodic paralysis (TPP) is a complication of hyperthyroidism. MATERIALS AND METHODS: We describe two patients with TPP. RESULTS: A 26-year-old man from Vietnam had weight loss, tachycardia, palpitations and heat intolerance for five months. Episodic leg and arm weakness developed three months after debut of symptoms. The second patient, a 23-year old woman from the Philippines, had had episodic leg weakness in the evenings after dinner for three weeks. Her attacks resolved spontaneously overnight. Physical examination of both patients revealed tachycardia and symmetrical proximal weakness involving both arms and legs. ECG and electrolyte analysis indicated a severe hypokalaemia; thyroid function tests showed hyperthyroidism. Both patients were diagnosed as having Graves' thyrotoxicosis and TPP. They were initially treated with propranolol and subsequently with carbimazole. The first patient had recurrence of thyrotoxicosis and paralysis after 16 months, whereas the second patient has remained symptom-free. INTERPRETATION: TPP is most common in Asian males, very few cases are reported in females. In Western countries TPP is rare, but with increasing immigration, TPP is likely to occur more frequently.

[Hyperprolactinemia and prolactinemia--investigation and treatment].

BACKGROUND: Prolactinoma represents the most commonly occurring hormone-secreting pituitary adenoma. The majority of prolactinomas are small, only rarely do we find larger prolactinomas, so-called macroadenomas. They are almost exclusively benign. The symptoms are mainly caused by elevated prolactin levels and result in changes to the reproductive and sexual function. In cases of macroprolactinomas, symptoms caused by local mass effects can be seen. A variety of other conditions may also cause hyperprolactinaemia; the goal of the examination is to identify the cause. MATERIAL AND METHODS: We have reviewed recent literature and compared findings with current management of hyperprolactinaemia and prolactinoma in Norwegian university hospitals. RESULTS AND INTERPRETATION: The primary treatment is medical, intended to normalize prolactin levels, restore gonadal function, and reduce tumour size. With the new selective dopamine agonists, the treatment is often simple and efficient, but not all patients are in need of treatment.

Thyrotoxicosis and paraparesis in a young woman: case report and review of the literature.

We describe a 23-year-old woman with a 3-week history of episodic leg weakness. The onset of weakness always occurred in the evening after dinner and the attacks resolved spontaneously by morning. Physical examination revealed a resting tachycardia and symmetrical, proximal weakness involving both arms and legs. Electrocardiogram (ECG) and electrolyte analysis showed a severe hypokalemia and thyroid function tests showed hyperthyroidism. The patient was diagnosed as having Graves' thyrotoxicosis and thyrotoxic periodic paralysis (TPP) and was initially treated with propranolol and subsequently carbimazole. No recurrence of the paralysis has been noted. TPP is most common in males of Asian extraction and is rare in women even in the Asian population. With increasing immigration, TPP is likely to occur more frequently in both Europe and North America and awareness of the condition is vital. Treatment of the underlying thyroid dysfunction cures the muscle symptoms.

Predictors of outcome and comparison of different drug regimens for the prevention of relapse in patients with Graves' disease.

OBJECTIVE: To investigate the effect of different antithyroid drug (ATD) regimens on relapse rates of Graves' disease, and to look for predictors of relapse. DESIGN AND METHODS: In a prospective two-way factorial randomized clinical trial, 218 patients with Graves' disease were assigned to ATD combined with l-thyroxine (l-T(4)) or ATD alone for 12 Months. After discontinuation of antithyroid therapy, each group was stratified to either 12 Months further treatment with l-T(4) or no treatment. Clinical and biochemical assessments were carried out before treatment, after 3 and 6 weeks, and every third Month for 12 Months. If the patients lacked symptoms of relapse, laboratory tests were performed every third Month for the second Year, and thereafter annually. RESULTS: The proportion of all patients with relapse was 47.7% 2 Years after withdrawal of ATD. There was no difference in relapse rates between the treatment groups (P=0.217, log--rank test). Smokers had a higher relapse rate than non-smokers (58.4% vs 38.8%, P=0.009). Patients who were thyrotropin-receptor antibody (TRAb) positive after 12 Months of antithyroid therapy had a higher relapse rate than those who were negative (72.5% vs 36.8%, P<0.0001). Similarly, relapse was more frequent (55.5%) in patients having large goiter compared with subjects with small goiter (36.3%, P=0.0007). CONCLUSIONS: Relapse rates of Graves' disease were independent of ATD regimen whether followed by l-T(4) therapy or not. Smoking, large goiter and presence of TRAb at the end of ATD therapy were strong predictors of relapse.
