Primary hyperparathyroidism due to an intrathyroidal parathyroid adenoma associated with chronic lymphocytic thyroiditis.

This is a case of a 44-year-old woman with an anterior neck mass and hypothyroidism who presented with an incidental finding of an elevated serum calcium level and was found to have primary hyperparathyroidism and osteoporosis. During surgical exploration no parathyroid adenoma was found, although a nodule was palpated within the right thyroid lobe. Examination of the excised right thyroid lobe revealed an intrathyroidal parathyroid adenoma and chronic lymphocytic thyroiditis. After surgery, she did not develop severe hypocalcaemia and this was attributed to preoperative treatment with pamidronate. In the months following surgery, parathyroid hormone remained undetectable.

Hypercalcaemia from genitourinary tuberculosis in a female with multiple exostoses.

The authors present a puzzling case of nephrolithiasis, hypercalcaemia, amenorrhoea, short stature and gross skeletal deformities in a 30-year-old female. Multiple pituitary hormone deficiency and metabolic bone disease were initially considered but were eventually excluded. The final diagnosis is genitourinary tuberculosis (TB) which caused the hypercalcaemia, nephrolithiasis and amenorrhoea, and also found to have the syndrome of multiple exostoses which explained the gross skeletal deformities and the short stature. After treatment with anti-TB therapy, there was resolution of hypercalcaemia and return of regular menstruation. The short stature and gross skeletal deformities remain as part of the congenital syndrome.

A giant myelolipoma discovered as an adrenal incidentaloma: radiological, endocrine and pathological evaluation.

A 51-year-old Filipino woman presenting with hypertension was unexpectedly found to have a large right adrenal mass by ultrasound. As she did not have symptoms of adrenal disease, this was labelled an adrenal incidentaloma. Ultrasound and CT imaging demonstrated a large adrenal mass on the right measuring 15 cm at its greatest diameter, with both benign and malignant features. Tests for endocrine hyperfunction (excess of cortisol, catecholamines and aldosterone) concluded that the mass was hormonally non-functioning. The patient eventually underwent open adrenalectomy. Histopathological examination revealed myelolipoma.

Prevalence of thyroid dysfunction among patients taking glutathione supplementation: A cross-sectional study preliminary report

BACKGROUND: Glutathione due to its favorable side effect of skin whitening has been used by cosmetic centers and by individuals buying it as an over the counter supplementation. Because of this, this compound is prone to misuse. To date, there are limited studies on the adverse effects of exogenous supplementation of glutathione.OBJECTIVE: To determine the prevalence of thyroid dysfunction among individuals taking oral and intravenous glutathioneDESIGN: Cross-sectional studyMETHODS:Healthy Filipino subjects, 21 to 50 years of age, currently taking oral or intravenous glutathione, with no preexisting/ known thyroid disease and history of radiation exposure, and not taking medications with known effect on thyroid function were included in the study. Blood extraction for thyroid function test and thyroid ultrasound were conducted.RESULTS: A total of 36 subjects were analyzed with a mean age of 36.3±8 years, 86 percent were female. High dose glutathione (1000mg or more per day) was taken in by nine subjects (25%) while 27 subjects (75%) took doses below the recommended range (less than 1000ng per day). The prevalence of abnormal thyroid function was 5.56 percent (n=2). Both cases were taking low dose glutathione supplementation. No abnormal thyroid function was seen with higher doses of glutathione. No significant relationship was found between the duration of glutathione supplementation with thyroid function status. Thyroid stimulating hormone (TSH) levels were slightly higher among those taking high dose glutathione (mean=1.08 versus 1.04, p=.81). There was no significant differences in the duration and dose of supplementation with the size of the gland.RECOMMENDATION:The direct effect of L-glutathione supplements on thyroid function must be established using a longitudinal prospective study design. We also propose a group to serve as a negative control during the comparisons.

Pituitary abscess manifesting with amenorrhea: A case report and review of literature

OBJECTIVE: To discuss a case of pituitary abscess presenting with amenorrhea and diabetes insipidus, and to enumerate the differential diagnosis for this conditionSIGNIFICANCE: By presenting this case, the author aims to increase awareness regarding the possibility of infectious causes of pituitary masses, thereby prompting early recognition and treatment of similar casesCASE REPORT: This is the case of a 42-year old woman admitted due to severe generalized headache, amenorrhea and polyuria of three months duration, preceded by a one-month history of remittent fever. Physical examination was normal except for bitemporal hemianopsiaLABORATORY TEST RESULTS: On admission, she had mild anemia, hypernatremia with elevated serum osmolality, and failure to concentrate urine. Hormonal examinations showed normal thyroxine and growth hormone levels, low basal serum cortisol, and elevated prolactin levels. Cranial CT scan showed widening of the sella turcica with a homogenous, isodense, slightly enhancing focus in the sellar and suprasellar area.COURSE: Initial considerations were chiasmatic glioma versus a pituitary adenoma. Transphenoidal surgery was done and intraoperatively, purulent fluid was noted. Aspirate gram stain showed 1-2 white blood cells per high power field but with no growth on culture. Subsequently, vision was fully restored but prolactin levels continued to be slightly elevated. Basal cortisol and urine specific gravity were persistently low. Repeat CT scan showed disappearance of the pituitary mass. Six months after the operation, the patient was able to go back to work but continues to take steroids and carbamazepine for the diabetes insipidus.REVIEW OF LITERATURE: There are about 100 cases of pituitary abscess in literature mimicking pituitary adenoma and presenting with headaches, amenorrhea, visual field cuts, hypopituitarism, fever and meningitis. As in this case, the abscess is frequently sterile. Pituitary abscess should be considered in patients with a primary diagnosis of pituitary adenoma with accompanying signs and symptoms suggestive of an infection. (Author)
