Purpose: Smoking has been linked with osteoporosis, but further evidence is required, especially concerning the effects of different types of tobacco smoking. We sought to examine the association between smoking and bone health in a large cohort of elderly Iranians.

Methods: The data from 2377 participants aged >60 years of Bushehr Elderly Health (BEH) program were used. Regardless of the type of smoking, participants were initially classified as non-smokers, ex-smokers and current smokers. Current smokers were also categorized based on the smoking type (pure cigarette, pure hookah and both). Dual-energy X-ray absorptiometry was used to evaluate bone density as well as Trabecular Bone Score (TBS). T-score ≤ -2.5 in either of the femoral neck, total hip or spinal sites was applied to determine the osteoporosis. The association of smoking and osteoporosis was assessed using multivariable modified Poisson regression model and reported as adjusted prevalence ratios (APR). The linear regression model was used to assess the association between smoking and TBS, adjusting for potential factors.

Results: A total of 2377 (1225 women) were enrolled [mean age: 69.3 (±6.4) years], among which 1054 (44.3%) participants were nonsmokers. In all, 496 (20.9%) participants were current smokers. Multivariable regression analysis revealed no significant association between smoking (either current or past) and osteoporosis in women. In men, current smoking was negatively associated with osteoporosis (APR: 1.51, 95%CI: 1.16-1.96). Among current users, cigarette smoking was associated with osteoporosis (APR: 1.57, 95%CI: 1.20-2.03); however, we could not detect a significant association between current smoking of hookah and osteoporosis. In men, a significant association was also detected between current cigarette smoking and TBS (coefficient: -0.03, 95%CI: -0.01, -0.04).

Conclusion: Current cigarette smoking is associated with both the quantity and quality of bone mass in elderly men. Although we could not detect a significant association between hookah and osteoporosis in men, considering the prevalence of hookah smoking in the middle eastern countries, further studies are needed to determine the effect of hookah smoking on bone health.

Background: Inflammation of the pituitary gland can occur in a variety of primary or secondary disorders. Idiopathic granulomatous hypophysitis is a rare inflammatory disease of the pituitary gland that can closely mimic a pituitary adenoma clinicoradiologically. Most authorities agree on minimally invasive transsphenoidal surgery as the mainstay in diagnosis and treatment of this disorder. There is still some controversy regarding pure medical management of idiopathic granulomatous hypophysitis in the literature.

Case Presentation: A 47-year-old Iranian woman of Azeri ethnicity with a history of benign breast cysts with a chief complaint of galactorrhea presented to our endocrinology clinic. Her past medical history was negative for any menstrual irregularities, hirsutism, visual complaints, diplopia, polyuria and polydipsia or seizures. She was taking 100 mcg of levothyroxine daily. Her familial history and physical examination were unremarkable. Her initial laboratory work-up revealed hyperprolactinemia (82.4 ng/mL) with otherwise normal pituitary axes. Brain magnetic resonance imaging showed a pituitary macroadenoma for which she was treated with 0.5 mg of cabergoline weekly. Although her serum prolactin level dropped to 1.7 ng/mL and her galactorrhea was resolved, she continued to complain of headaches and nausea. Repeated imaging showed no decrease in size of the macroadenoma. Therefore, she underwent transsphenoidal surgery of the macroadenoma which was reported as chronic granulomatous hypophysitis by expert pathologists. Tuberculosis, sarcoidosis, Wegener's granulomatosis, Langerhans cell histiocytosis, and syphilis were ruled out by appropriate tests and she was diagnosed as having idiopathic granulomatous hypophysitis. Fortunately, her condition was not complicated by hypopituitarism and she was symptom free 9 months after transsphenoidal surgery.

Conclusions: Idiopathic granulomatous hypophysitis, a rare inflammatory disease of the pituitary gland, is a diagnosis of exclusion for which both medical and surgical management are reported in the literature. We present a case of idiopathic granulomatous hypophysitis who was symptom free with no complications of hypopituitarism following its transsphenoidal resection after 9 months of follow-up.
