The authors present two middle-aged female patients with empty sella revealed at imaging studies (CT, MRI). Their main complaint was severe fronto-parietal and fronto-temporal headache. Physical examination showed obesity, hypertension, and local hypersensitivity on deep palpation and percussion in the above-mentioned regions, in both cases. Endocrine function of pituitary gland, visual fields and fundi were normal as was EEG. The CSF composition and pressure also showed no abnormalities. The diagnostic and therapeutic problems of empty sella syndrome are discussed.

The case of a decompression sickness in woman, diving to 26 meter depth is reported. The patient was helped by instructor's computer (error!) and she presented risk factors for embolic disease (obesity, smoke, estroprogestinic therapy). She presented with many symptoms of decompression sickness during immersion and during re-ascent (headache, vertigoes and paresthesias). She was not treated on the place of incident, but only 36 hours later at our center of hyperbaric medicine. Her Magnetic Resonance imaging showed hyperintensity lesions of white matter.

Idiopathic intracranial hypertension (IIH), or pseudotumor cerebri, is a syndrome characterized by an elevated intracranial pressure in the absence of a focal lesion, infective process, or hydrocephalus. New onset IIH may present to the emergency department in a variety of ways. To describe the etiologic associations and clinical features in this disorder, we performed a retrospective analysis of consecutive emergency department patients with new onset IIH during the calendar years 1987-1996. A total of 52 patients met all study criteria. The mean patient age was 27+/-8.9 years; the female-to-male ratio was 7:1. An etiologic association could be identified in 85% of cases and included obesity, hypertension, drugs, endocrine, and systemic disorders. Headache was a dominant complaint in most patients (48/52) and associated with dizziness, nausea, and/or visual complaints. Fourteen patients (27%) were not diagnosed on their initial ED visit and were more likely to have atypical clinical features (71% vs. 24%; P = .004). Atypical features included paraesthesias, neck/back pain, unilateral headache, vertigo, and nystagmus. Papilledema, the ophthalmoscopic hallmark of IIH, was not detected initially in 11 patients (21%). These results suggest that IIH is a relatively uncommon neurological illness that may have a variety of causes. The emergency department diagnosis may be complicated by atypical clinical features and a lack of detectable papilledema.

Recently, 5-hydroxy-L-tryptophan (5-OHTrp) has been promoted as an alternative to banned L-tryptophan as a dietary supplement. It has been claimed to help alleviate obesity, insomnia, depression, and headaches. However, eosinophilia-myalgia syndrome (EMS)-like symptoms have also been associated with ingestion or exposure to 5-OHTrp. HPLC-UV analysis of EMS-implicated 5-OHTrp revealed the presence of peak X, described as case-implicated. We show that peak X is actually a family of contaminants with the same molecular weight (234 Da) and similar HPLC retention times. We also demonstrate that all eight samples of commercially available 5-OHTrp analyzed by HPLC-MS contained three or more contaminants of the peak X family. The significance of these findings is discussed.

Sleep problems (i.e., insomnia) affect midlife women as they approach and pass through menopause at rates higher than at most other stages of life. The purpose of this article is to critically review what is known about insomnia (perceived poor sleep) and physiologically assessed sleep, as well as sleep-related disordered breathing (SDB), in women according to menopausal status and the role of hypothalamic-pituitary-ovarian (HPO) hormones. Self-report evidence that sleep difficulties are related to the hormonal changes of menopause is mixed. Data from studies in which sleep was physiologically measured reveal that sleep problems appear corequisite with hot flashes and sweats. Results are difficult to compare across studies because of varying methodologies in how sleep quality and patterns were assessed and how age cohorts and menopausal status were defined. The risk of SDB increases with age, although women are less susceptible at any age than men. As with men, snoring, obesity, and high blood pressure are clear risk factors. Some women may be underdiagnosed for SDB, as they have somewhat different symptom manifestations than men. Usually, frank apnea is not as evident. Primary care clinicians should be mindful of the potential for SDB in women who are obese, have high blood pressure, are cognizant of snoring, and report morning headaches and excessive daytime sleepiness. Improved care will result from consistently incorporating sleep insomnia assessments into practice as a basis for referring to sleep centers as necessary or prescribing sleep-enhancing behavioral and pharmacological treatments.

We studied prospectively the etiology, clinical presentation, and outcome of idiopathic intracranial hypertension in 36 patients (20 boys and 16 girls) aged 3.5 months to 14 years. The etiology was identified in 28 (77.7%) patients. The most common predisposing factor was middle-ear infection, followed by obesity. Of the 36 cases seen, 26 presented with the classic picture of headaches, papilledema, and elevated cerebrospinal fluid pressure; 8 children had intracranial hypertension in the absence of papilledema and 2 had fundoscopic evidence of papilledema with normal cerebrospinal fluid pressure initially. In four children resolution of intracranial hypertension occurred with removal of the causative agent or appropriate treatment of the underlying condition. In 8 of 17 patients intracranial hypertension resolved with acetazolamide therapy and in 22 of 24 patients it resolved with corticosteroids in combination with acetazolamide. Subnormal visual acuity, narrowing of visual fields, or both were present on the initial examination in 10 patients; 2 of them, who presented with loss of vision, have permanent visual impairment. Four additional patients presented a transient, mild impairment of visual acuity during treatment. Our study confirms the wide clinical spectrum and the difficulties encountered in diagnosis of idiopathic intracranial hypertension. A wide variety of etiologic associations should be investigated to provide definitive therapy. Loss of visual function is the only serious complication.

To design a self-administered screening questionnaire to inform men about their risk for testosterone deficiency. The screener was developed in two phases. First was a construction phase in which relevant risk factors and a scoring algorithm were defined from multiple logistic regression analyses of survey data. In the second phase, the screener's accuracy (based on sensitivity, specificity, and Receiver Operating Characteristic (ROC) curves) was tested using patients from a primary care clinic. All subjects provided blood samples for endocrine testing. Survey data from 1660 men aged 40-79 years participating in the Massachusetts Male Ageing Study (MMAS) were analysed in the first phase. The clinic sample consisted of 304 men aged 40-79 years presenting at a large Massachusetts primary health care clinic for routine check-ups or minor medical problems. The primary outcome was testosterone deficiency, defined as serum total testosterone below 12.1 nmol/l. Self-reported variables considered as potential risk factors included age, obesity, chronic diseases, health behaviour, the Jackson dominance scale, and symptoms of stress. The prevalence of testosterone deficiency was 20.4% in the MMAS and 42.1% in the clinic sample. An eight-item screener was developed based on age, body mass index, diabetes, asthma, headaches, sleep patterns, dominance preferences, and smoking status. The screener performed significantly better than chance in identifying men with low testosterone levels; the area under the ROC curve was 0.66 in the MMAS sample and 0.67 in the clinic sample. The self-scored screener developed in this study reliably detects men at risk of hypogonadism. The screener encourages at risk men to seek professional evaluation of their testosterone levels.

A 60-year-old woman presented with a history of palpitations, headaches and severe hypertension, which was resistant to hypotensive agents. She had a 2-year history of obesity and a moon face. Her plasma adrenocorticotropic hormone level was below the limits of detection and did not respond to corticotropin-releasing hormone. Urinary-free cortisol was elevated and the circadian rhythm of serum cortisol level had completely disappeared. Imaging analysis demonstrated a unilaterally functioning mass in the left adrenal gland. Serum cortisol level in the left adrenal vein was elevated. The resected adrenal mass measured 4 x 3.5 x 2.5 cm, and ranged from yellow to tan in color. The adrenal cortex adjacent to the nodule did not demonstrate cortical atrophy. The mass was well circumscribed but not encapsulated, and consisted of multiple cortical nodules. These nodules were composed predominantly of clear cortical cells, and partly of compact cortical cells. Immunoreactivity of steroidogenic enzymes including cholesterol side-chain-cleavage P450, 3beta-hydroxysteroid dehydrogenase, 21-hydroxylase cytochrome P450, 11beta-hydroxylase cytochrome P450 and 17alpha-hydroxylase cytochrome P450 was marked in cortical nodules, but minimal in non-nodular cortex. Ultrastructural examination of nodular cortical cells also demonstrated well-developed mitochondria and smooth endoplasmic reticulum, consistent with elevated steroidogenesis in these cells.

An autopsy case of a patient with diffuse brainstem glioma associated with Laurence-Moon-(Bardet-)Biedl syndrome is described. The subject was a 25-year-old woman who had been suffering from mental retardation, pigmented retinopathy, obesity, hexadactyly, amenorrhea and renal cysts. She developed dizziness, headache and consequent consciousness disturbance. Magnetic resonance images disclosed marked swelling of the pons without contrast enhancement. By means of combined chemotherapy and radiation, she survived for 15 months. Histopathological diagnosis for postmortem specimens obtained from the brainstem was glioblastoma multiforme. No pathogenetic association between the syndrome and brainstem gliomas is known, and the literature contains no cases of patients with this coincidence.

The study analyzes the prevalence of cardiovascular risk factors in 1343 patients with severe headache (399 men and 944 women), aged 15 to 64 years; analyses were controlled for sex, age, and type and frequency of headache. Prevalence of various forms of headache was different between men and women. Age and days per year with headache were significantly different among various forms of headache. For men and women with headache, age directly related to prevalence of hypertension, hypercholesterolemia, and obesity. Due to low prevalence, analyses by age were not done for diabetes mellitus. For cigarette smoking, prevalence was not related to age in men, but was inversely related to age in women. With control for age, prevalence of cardiovascular risk factors was not significantly different among patients with different forms of headache, except for cluster headache. Among men with cluster headache, prevalence was high for cigarette smoking, but low for hypercholesterolemia. With control for age, days per year with headache did not relate to prevalence of cardiovascular risk factors except for cigarette smoking in men. Compared to data for a population sample used as control, patients with headache had higher prevalence of hypertension in both sexes, independent of age (odds ratio 1.51, 95% confidence interval 1.28 to 1.80); the difference between patients with headache and the control population was lower with increasing age. The high prevalence of hypertension among patients with headache was not due to overweight. The data indicate that headache is significantly associated with hypertension, but not with other cardiovascular risk factors.
