Pulmonary neuroendocrine (carcinoid) tumors: European Neuroendocrine Tumor Society expert consensus and recommendations for best practice for typical and atypical pulmonary carcinoids

This is an expert consensus from the European Neuroendocrine Tumor Society recommending best practice for the management of pulmonary neuroendocrine tumors including typical and atypical carcinoids. It emphasizes the latest discussion on nomenclature, advances and utility of new diagnostic techniques as well as the limited evidence and difficulties in determining the optimal therapeutic strateg

Pregnancy and other pituitary disorders (including GH deficiency)

The pituitary gland is one of the most affected organs with altered anatomy and physiology during pregnancy. Acromegaly is the second most common pituitary adenoma seen in relation to gestation after prolactinomas. Acromegaly should be treated before conception to prevent potential tumor growth in patients who desire fertility. Medical therapy can be ceased safely after confirmation of pregnancy in acromegalic patients, but octreotide may be used in selected cases with compressive signs. Other hormonal and non-functional tumors are rarer and have been presented as case reports. Sheehan's syndrome, which is one of the most common causes of hypopituitarism in developing countries, and lymphocytic hypophysitis are known to be associated with pregnancy. They usually result in hypopituitarism, sometimes with delays in diagnosis and difficulties in differential diagnosis. Pregnancy is not common among patients with hypopituitarism or pituitary adenomas due to altered gonadotroph functions. Ovulation induction is essential for fertility achievement, but the replacement of other deficient pituitary hormones, including GH, seems to play an important role in the preparation of the uterus for implantation of the embryo.

Pituitary function in subjects with mild traumatic brain injury: a review of literature and proposal of a screening strategy

Traumatic brain injury (TBI) is an important public health problem all over the world. The level of consciousness of the patients and the severity of the brain injury is commonly evaluated by the Glascow Coma Scale as mild, moderate and severe TBI. When we consider the high frequency of mild TBI (MTBI) among the all TBI patients the burden of the pituitary dysfunction problem in this group could not be ignored. However, one of the most important and still unresolved questions is which patients with MTBI should be screened for hypopituitarism? Another type of head trauma which could be considered as the subgroup of MTBI is sports related chronic repetitive head trauma. Therefore, in this review we will discuss the frequency, characteristics and current management of pituitary dysfunction in patients with MTBI including the subjects exposed to sports related chronic mild head trauma

The evaluation and treatment of hirsute women

Hirsutism in women is defined as an excess of body hair in the androgen-sensitive skin regions. The different genetic backgrounds of various populations may affect the causes of hirsutism. In fact, the most important reason for investigation is to identify those women with androgen-secreting tumors, since they require different therapy. Hirsutism may have various causes, such as polycystic ovary syndrome, enzyme defects in adrenal steroid biosynthesis, Cushing's syndrome, acromegaly, ovarian or adrenal tumors, or it may be idiopathic. In most patients, hirsutism is associated with hyperandrogenemia and the most common cause of androgen excess is polycystic ovary syndrome. Androgen-secreting tumors should be suspected when the onset and progression of hirsutism is rapid and/or when it is associated with virilization. Patients should be informed about the type and duration of therapy. The selection of drug/drugs depends on the severity of the hirsutism, associated conditions such as menstrual irregularities, systemic disorders such as diabetes mellitus, hypertension and any contraindication to possible therapeutic agents. Diane((R)) 35 is the most common drug used for the suppression of ovarian androgen production. Peripheral blockade of androgen actions, by using spironolactone, finasteride or flutamide on the skin, is also effective in the treatment of hirsutism

Growth hormone replacement therapy in adults with growth hormone deficiency: Benefits and cost-effectiveness

In recent years, growth hormone deficiency in adults has been accepted as a clinical entity. Although beneficial effects of growth hormone replacement therapy (GHRT) in adults - including improvements in body composition, lipid profile, quality of life and bone mineral density - have been shown in many studies, there are still controversies and ongoing debates regarding GHRT in adults. It seems that this subject will continue to be a hot topic in the near future. Therefore, the aim of this review is to re-evaluate the current understanding on GHRT in adults in the light of recent data. Additionally, the clinical aspects, risks, benefits and cost-effectiveness of GHRT are summarized. © 2006 Future Drugs Ltd

Non polycystic ovary syndrome-related endocrine disorders associated with hirsutism

Background Hyperandrogenism refers to classical androgen-dependent signs such as hirsutism, acne and androgenetic alopecia. Hirsutism is the main hyperandrogenic symptom, defined as an excess of body hair in the androgen-sensitive skin regions of the women. In this review, we attempt to focus on the pathogenesis of hirsutism related to disorders other than polycystic ovary syndrome (PCOS). Also, we will discuss their clinical and biochemical features as well as therapeutic options. Design Several original articles, meta-analysis and reviews have been screened in the field of hirsutism and hyperandrogenic disorders. Results Current English literature including our studies suggests that PCOS is the most common cause of hirsutism. The most important purpose for investigation is to identify those women with androgen-secreting tumours because of their life-threatening potential. In approximately 18% of the women with hirsutism, the underlying cause is nonclassical adrenal hyperplasia because of 21-hydroxylase deficiency. Depending on ethnicity and the geographic area, idiopathic hirsutism constitutes 517% of the patients with hirsutism. Approximately 3% of hyperandrogenic women were observed to suffer from hyperandrogenic-insulin-resistant acanthosis nigricans syndrome. More rare causes are glucocorticoid resistance syndrome, hyperprolactinemia, acromegaly, Cushings syndrome and some drugs. Specific causes of hirsutism such as Cushings syndrome and adrenal/ovarian tumours should be treated specifically. In other patients, pharmacological approach is the mainstay of therapy. Conclusions A number of patients presenting with hirsutism and exhibiting similar features to PCOS may have other underlying diagnoses. Unlike PCOS, some of these disorders can occasionally be life threatening and require prompt diagnosis and treatment

Pituitary dysfunction due to sports-related traumatic brain injury

PurposeAfter traumatic brain injury was accepted as an important etiologic factor of pituitary dysfunction (PD), awareness of risk of developing PD following sports-related traumatic brain injury (SR-TBI) has also increased. However there are not many studies investigating PD following SR-TBIs yet. We aimed to summarize the data reported so far and to discuss screening algorithms and treatment strategies.MethodsRecent data on pituitary dysfunction after SR-TBIs is reviewed on basis of diagnosis, clinical perspectives, therapy, screening and possible prevention strategies.ResultsPituitary dysfunction is reported to occur in a range of 15-46.6% following SR-TBIs depending on the study design. Growth hormone is the most commonly reported pituitary hormone deficiency in athletes. Pituitary hormone deficiencies may occur during acute phase after head trauma, may improve with time or new deficiencies may develop during follow-up. Central adrenal insufficiency is the only and most critical impairment that requires urgent detection and replacement during acute phase. Decision on replacement of growth hormone and gonadal deficiencies should be individualized. Moreover these two hormones are abused by many athletes and a therapeutic use exemption from the league's drug policy may be required.ConclusionsEven mild and forgotten SR-TBIs may cause PD that may have distressing consequences in some cases if remain undiagnosed. More studies are needed to elucidate epidemiology and pathophysiology of PD after SR-TBIs. Also studies to establish screening algorithms for PD as well as strategies for prevention of SR-TBIs are urgently required

The Effects Of Oligofructose And Polydextrose On Metabolic Control Parameters In Type-2 Diabetes

Objective: This study investigated the effects of oligofructose and polydextrose on metabolic control in Type-2 diabetes. Methodology: Twenty voluntary, postmenopausal, total cholesterol (TC)/HDL-cholesterol (HDL-C) ratios >4.5, female, Type-2 diabetes patients were included. The study was performed in four periods, with the baseline as the period one. In periods two and four, the patients consumed individual diabetic diets for eight weeks. In period three, they consumed 20g of oligofructose and potydextrose mixture in 40g sweetener (in powdered form), added to their diets for six weeks. Results: Prebiotic soluble fiber sources (oligofructose and polydextrose) significantly decreased fasting and postprandial (2-hour) blood glucose, glycosylated hemoglobin, TC, LDL-cholesterol (LDL-C), TC/HDL-C and LDL-C/HDL-C ratios, triglyceride, VLDL-cholesterol, lipoprotein (a), systolic and diastolic blood pressures (p0.05) compared to the initial values, respectively. Conclusion: Individual diabetic diets supplemented with prebiotics improved metabolic control in Type-2 diabetes.Wo

Sella turcica: an anatomical, endocrinological, and historical perspective

The sphenoid bone has a superior depression called the sella turcica, Latin for "Turkish saddle," where the pituitary gland is found. The availability of modern radiological imaging techniques has replaced plain radiography of the sella turcica in the investigation of hypothalamo-pituitary abnormalities. However, the size of the sella turcica, and smaller sella turcica size in particular, may cause pituitary dysfunction because of the changes in the structure of pituitary gland or may be associated with some genetic or acquired endocrine disorders. The name "sella turcica" is one of the most commonly used terms in everyday endocrine practice
