We describe an epidemic of self-limited (6 weeks) thyrotoxicosis which affected 12 index cases, 5 household contacts, and 6 retrospectively identified cases in July, August, and September, 1987 in the town of Winterswijk (28,011 inhabitants), The Netherlands. A small goiter was present in 9 of the 12 index patients, tender upon palpation in only 2. Signs and symptoms of thyrotoxicosis were accompanied by a low grade fever in combination with fatigue, headache, myalgia, and a fine desquamation of the palms and soles. The apparent incubation time between family members was 6 days. Thyroid technetium uptake was decreased in 10 of 11 tested patients. Laboratory findings included elevated sedimentation rates (up to 68 mm/h), increased liver enzymes, lymphopenia in 2 patients, and absence of thyroid autoantibodies. HLA-B35, associated with classical subacute thyroiditis, was found in 1 patient only. An etiological agent was not identified. No evidence was found for thyrotoxicosis factitia. After 10 months, all patients were euthyroid, without a goiter or thyroid autoantibodies. Thus, a new variant of thyroiditis, atypical subacute thyroiditis, was probably the cause of this unusual outbreak. It is unclear at present if this variant of thyroiditis is common in communities and represents a separate disease entity.

Pituitary apoplexy is characterized by a wide spectrum of clinical features. A quite rare case of painless thyroiditis, hypopituitarism and central diabetes insipidus (DI) followed by pituitary apoplexy was presented. A 61-year-old woman was admitted to our hospital in May, 1986 because of marked general malaise, polydipsia and weight loss which became progressively worse. Four months earlier she had experienced episodes of abrupt onset of severe headache associated with nausea and blurring vision. Physical examinations revealed a fine tremor, dry skin and nervousness. The thyroid gland was not palpable. Visual fields were intact. Her blood pressure was 105/64 mmHg with variable tachycardia. The routine laboratory studies were normal or negative except for hypoalbuminemia, hypocholesterolemia and hypernatremia. Erythrocyte sedimentation rate was 12 mm/hr. An impairment in corticotropin secretion was suspected from the low plasma cortisol and the low urinary excretion of 17-OHCS and the sufficient response to ACTH. Basal levels of GH and gonadotropin were also low, and responses to the stimulation tests (Insulin-stress, L-DOPA, and LH-RH) were all blunted. Brain computed tomographic scan and magnetic resonance imaging demonstrated a suprasellar mass that, after infusion, developed peripheral ring-like enhancement and large hyperintense pituitary mass, respectively. A diagnosis of pituitary apoplexy with anterior pituitary failure was made. However, the initial levels of thyroid hormones showed elevated as follows: Free T3 7.6 pg/ml, Free T4 3.3 ng/dl and T3-resin uptake 41.1%. TSH responses to TRH were all suppressed. TSH receptor antibody (TBII) was negative. Both antithyroglobulin and antimicrosomal antibodies were repeatedly positive. A thyroid scan with 99mTc revealed no uptake in the thyroid area. These findings led us to the diagnosis of "painless autoimmune thyroiditis". She had become hypothyroid without any medication. At that time radioactive 99mTc and 123I uptakes increased significantly. When hydrocortisone was substituted, daily urine output abruptly increased to about 10 liters with low osmolality, and the presence of DI was suspected. This diagnosis was confirmed by water deprivation and hypertonic saline infusion tests and subsequent pitressin test. She is currently quite well on L-thyroxine, hydrocortisone and desmopressin (1988). This association with pituitary apoplexy must be a rare occurrence, as a literature search has failed to find a similar case. The pathogenetic trigger of "painless thyroiditis" in this case may be responsible for some immunological change due to secondary adrenal insufficiency after pituitary apoplexy.

Since their initial description in 1957, the interferons (IFNs) have been increasingly used to treat a wide array of diseases. Acute adverse effects, i.e. 'flu-like' syndromes, hypo- or hypertension, tachycardia, headache, myalgias and gastrointestinal disorders, occur within the first hour or day after starting treatment. They are seldom treatment-limiting and are easily manageable. Sub-acute and chronic effects develop after several days, usually within 2 and 4 weeks of therapy. The most typical is neurological toxicity, including fatigue/asthenia, and behavioural and cognitive changes. Such symptoms may seriously impair quality of life and result in treatment discontinuation. Seizures have seldom been described. Other infrequent central nervous system adverse effects include vertigo, cramp and oculomotor nerve paralysis. Distal paraesthesias and peripheral neuropathy have been reported. IFN-associated autoimmunity is quite rare but a matter of concern. Biological or clinical manifestations usually require several months to become apparent. Autoantibodies have been shown to develop in most patients but have been inconsistently associated with clinical symptoms of systemic lupus erythematosus, rheumatoid-like arthritis and thyroiditis. Both hypo- and hyperthyroidism have been described but are usually reversible. Other infrequent autoimmune reactions include diabetes, pemphigus and worsening of multiple sclerosis. Although several patients present with a pre-existing autoimmune disorder, no predisposing factor has been clearly established. While hypotension and tachycardia are the most frequent acute cardiovascular complications, a few additional cases of cardiac arrhythmias and myocardial ischaemia have been reported after a short course or several weeks of treatment. These latter complications do not appear to be dose-dependent or age-related. Isolated cases of congestive heart failure have also been described. Mild proteinuria has been observed in 15 to 25% of patients, but acute renal toxicity is uncommon. A transient rise in serum aminotransferase levels is frequently noted during the first stage of therapy, especially in patients receiving the highest dosages. Direct hepatotoxicity is extremely rare. Autoimmune hepatitis, which is ill-diagnosed as chronic viral hepatitis, and de novo induction of autoimmune hepatitis, account for the majority of liver diseases. Haematotoxicity is relatively common but mild to moderate, and develops gradually during the first weeks of treatment. Neutropenia is the most common haematological toxicity, but is usually not dose-limiting and resolves rapidly upon drug discontinuation. Myelosuppression, autoimmune and immune allergic haemolytic anaemias and thrombocytopenias have seldom been described. Cutaneous adverse effects comprised nonspecific erythema and hair loss and, less frequently, vasculitis, local ulcerations at the site of injection and exacerbation of psoriasis.(ABSTRACT TRUNCATED AT 250 WORDS)

A 57-year-old woman came to our hospital with complaints of neck swelling and headache in 1991. She was diagnosed as having chronic thyroiditis in euthyroidism because she had a diffuse goiter with both antithyroglobulin antibody (TGHA) and antimicrosomal antibody (MCHA). In 1992, she complained of the rapid growth of her thyroid gland and a swallowing disturbance. Atypical lymphocytes were observed in 16.5% of leukocytes in peripheral blood and similar atypical cells were found in bone marrow. Although an ultrasound scan of the thyroid gland revealed a symmetrical enlargement without a pseudocystic appearance, cytological study with fine needle aspiration biopsy of the thyroid gland demonstrated an abundance of atypical lymphoid cells. A whole body scintigram with 67gallium citrate showed no significant accumulation except in the thyroid gland. With a diagnosis of suspected primary thyroid lymphoma, total thyroidectomy was performed. However the diagnosis of malignant lymphoma was not confirmed histologically. A study of lymphocytes subset with two-color flow cytometry, which was performed for both lymphocytes in peripheral blood and infiltrating lymphocytes in the resected thyroid gland, revealed abnormal increased CD4 positive T cells and decreased HLA-DR expression. Additionally, southern blot DNA analysis for abnormal lymphocytes using restriction enzymes, EcoRI and BamHI, demonstrated rearrangement of the T-cell antigen receptor, which indicates a monoclonal proliferation of lymphocytes. After total thyroidectomy, atypical lymphocytes in peripheral blood decreased, and circulating autoantibodies including TGHA and MCHA disappeared. From these data, this patient was finally diagnosed as having a primary T-cell lymphoma of the thyroid gland, which is a very rare type of thyroid lymphoma.(ABSTRACT TRUNCATED AT 250 WORDS)

A 16-year-old male complained of a headache and a high fever followed by polyuria. The endocrinological studies showed he had hypopituitarism and central diabetes insipidus, and magnetic resonance imaging (MRI) revealed a pituitary mass. Diabetes insipidus gradually improved and hydrocortisone treatment was begun at three months after onset, but a month later painless thyroiditis developed. An MRI demonstrated a spontaneous shrinkage of the pituitary mass nine months after onset. Lymphocytic hypophysitis followed by painless thyroiditis was the most probable diagnosis, although it is very uncommon especially among men.

An open, multicentre study was undertaken in order to evaluate the efficacies and safety profiles of azithromycin and roxithromycin in 440 adults with acute otitis media, sinusitis or acute beta-haemiolytic streptococcal pharyngitis/tonsillitis. Treatment with 500 mg azithromycin, administered orally once daily for 3 days, produced a satisfactory clinical outcome (cure or improvement) in 51/52 (98%) patients with otitis media, 91/91 (100%) patients with pharyngitis/tonsillitis and 64/68 (94%) patients with sinusitis. Treatment with 150 mg roxithromycin, given orally twice daily for 10 days, produced satisfactory clinical responses in 54/55 (98%), 91/92 (99%) and 69/73 (94%) patients with otitis media, pharyngitis/tonsillitis and sinusitis respectively. Of the 17 azithromycin-treated patients with sinusitis who were clinically and bacteriologically evaluable, Staphylococcus aureus persisted in two and Streptococcus pneumoniae in one. S. aureus also persisted in 1/12 clinically and bacteriologically-evaluable patient treated with roxithromycin. Of the 58 and 64 patients with pharyngitis/tonsillitis treated with azithromycin and roxithromycin, respectively, who were clinically and bacteriologically evaluable, Streptococcus pyogenes persisted at the end of treatment in 7/58 (12%) in the azithromycin group and in 13/64 (20%) in the roxithromycin group. At follow-up, there was no evidence of S. pyogenes reinfection in patients treated with azithromycin. Three episodes of reinfection occurred in the roxithromycin treatment group. Also, three patients showed evidence of clinical relapse at follow-up, although no pathogens were isolated. Azithromycin was associated with a lower incidence of adverse events. No azithromycin-treated patient was withdrawn prematurely because of a treatment-related event. Three roxithromycin-treated patients were withdrawn from treatment because of severe headache, thyroiditis or fatigue. In conclusion, for adults with acute upper respiratory tract infections, a 3-day course of once-daily azithromycin was found to be as effective and as well tolerated as a 10-day course of twice-daily roxithromycin.

A patient of craniopharyngioma associated with intratumoral bleeding was reported. A 44-year-old female was admitted to our department with sudden onset of headache suggesting pituitary apoplexy. On admission, she complained of mild bifrontalgia and neurological examination revealed no abnormality except bitemporal hemianopsia. Hormonal examination indicated hypopituitarism with masked diabetes insipidus and chronic thyroiditis. MRI showed a cystic 12 x 10 x 10 mm tumor with an enhanced rim at the intra- and suprasellar region. The MRI findings of the cyst suggested intratumoral bleeding with various stages. CT and plain tomography revealed plane calcification adjusting or aligning itself to the floor of the sellar. This calcification was difficult to distinguish from the sellar floor on MRI. Under the diagnosis of craniopharyngioma, almost all of the tumor was removed, using the transsphenoidal approach. The cyst consisted of old hematoma and cholesterin. The histological examination revealed a stratified squamous epithelia with numerous immature blood vessels. Such findings are unusual in cases of craniopharyngioma. Craniopharyngioma is rarely associated with intratumoral hemorrhage. The mechanism of this hemorrhage was discussed with reference to the literature on this subject.

We describe the exceptional association of Vogt-Koyanagi-Harada syndrome (VKHS) and hypothyroidism in a 29-year-old man of Indian heritage. VKHS is a rare uveomeningoencephalitic syndrome with probably autoimmune pathogenesis. Nontraumatic uveitis, aseptic meningoencephalitis, vitiligo, alopecia and poliosis are the leading clinical features of VKHS. The reported patient presented with bilateral visual loss and progressive frontal headache. VKHS was diagnosed due to characteristic ophthalmological findings and the diagnosis of aseptic meningitis. Due to the autoimmune pathogenesis, VKHS may be rarely associated with other autoimmune disorders. Association of VKHS with autoimmune thyroid disease has been described in the literature in three patients. In the reported case hypothyroidism due to chronic autommune thyroiditis was diagnosed in association with VKHS. Routinely determination of thyroid function in patients with VKHS is recommended.

This report describes the clinical and pathological characteristics of two patients with lymphocytic hypophysitis (LHy) and two with infundibuloneurohypophysitis (INHy). Two of the patients were women and two were men, and their ages were between 27 and 38 years old. This disease was not associated with either pregnancy or the postpartum period in the female patients. Two of the patients presented with diabetes insipidus, one with panhypopituitarism and right abducens paralysis and one with headache and galactorrhea. At presentation three of the patients had mild to moderate hyperprolactinemia and one had low prolactin levels. All four had abnormal magnetic resonance imaging (MRI): focal nodular enlarging of the infundibulum and normal hypophysis in one, expanding sellar masses in two, and diffusely thickened stalk with slightly enlarged pituitary gland in one. Three cases showed no sign of adenohypophysial deficiency with stimulation tests. One patient had associated chronic lymphocytic thyroiditis. Of the first three patients, one patient underwent transcranial and two underwent transnasal transsphenoidal (TNTS) surgery for mass excisions since they were thought to have pituitary tumors. Endoscopic endonasal transsphenoidal biopsy was performed in the last one with a suspicion of LHy. The pathological and immunohistochemical examinations revealed lymphocytic infiltration. Hyperprolactinemia resolved with surgery in two patients and one developed diabetes insipidus as a complication. We conclude that LHy and infundibuloneurohypophysitis should be considered in the differential diagnosis of the mass lesions of the sellar region and also should be kept in the mind for the etiopathogenesis of cases of hyperprolactinemia, galactorrhea and diabetes insipidus. In suspected cases endoscopic endonasal biopsy for the histopathological diagnosis can be a safe approach.

Autoimmune thyroiditis, the most frequent cause of acquired hypothyroidism in childhood and adolescents, is characterized by raised levels of the specific antibodies to thyroperoxidase (TPOAb) and thyroglobulin (TgAb). We report a girl aged 10 years and 9 months who presented with arrested growth and breast development (thelarche). She also exhibited myxedema of the face and legs, prominent striae on the thighs, dry, cold skin, and hypertrichosis on her back. There was no goiter, no history of thyroid pain and no family history of thyroid disease. She complained occasionally of a transient headache. The patient's height was below the 3rd percentile, while her body weight was at the 50th percentile and bone age was normal. Laboratory tests proved severe hypothyroidism (fT4 0 ng/dl, fT3 0.99 pg/ml, TSH >100 microIU/ml plus an increased titer of TPOAb). Thyroid ultrasound supported the diagnosis of thyroiditis. Pituitary PRL and FSH levels and peripheral estradiol were all elevated. L-Thyroxine therapy, instituted following diagnosis, improved the growth velocity to 11 cm/year and the FSH and E2 levels were normalized to prepubertal values. Complete regression of the breast development was observed within 4 months. However, 4 months later a true (central), isosexual LHRH-dependent puberty started. The pubertal features at the time of the original diagnosis might be explained by: 1. the direct action of elevated TRH on gonadotropes to stimulate gonadotropin secretion and on lactotrophes to stimulate PRL secretion, and 2. TSH action on LH and mostly FSH receptors (homologous to TSH receptors) in the ovary, stimulating the secretion of estradiol.
