PURPOSE: The standard evaluation of multisystem Langerhans cell histiocytosis (LCH) includes a clinical evaluation, laboratory tests and a skeleton/skull X-ray survey, with chest high-resolution computed tomography (HRCT) in the case of pulmonary involvement. Preliminary reports suggest that (18)F-fluorodeoxyglucose positron emission tomography-computed tomography ((18)F-FDG PET-CT) may be useful for evaluating patients with LCH. METHODS: Fourteen consecutive adult patients with multisystem LCH were included in this retrospective study, and were evaluated using standard procedures and (18)F-FDG PET-CT...

UNLABELLED: The case report shows a surprising presentation of pulmonary granulomatosis with polyangiitis (GPA) through symptoms of diabetes insipidus (DI) with granulomatous infiltration of the pituitary gland. The pituitary hormonal dysfunction as a result of granulomatosis of the pituitary gland is rare. Several studies have demonstrated that the incidence of the pituitary dysfunction reaches approx. 1 % of the patients with GPA. However it is mostly presented in patients with the disease already diagnosed...

Ghrelin is a small peptide released primarily from the stomach. It is a potent stimulator of growth hormone secretion from the pituitary gland and is well known for its regulation of metabolism and appetite. There is also a strong relationship between ghrelin and the cardiovascular system. Ghrelin receptors are present throughout the heart and vasculature and have been linked with molecular pathways, including, but not limited to, the regulation of intracellular calcium concentration, inhibition of proapoptotic cascades, and protection against oxidative damage...

Langerhans cell histiocytosis is characterized by the abnormal nodular proliferation of histiocytes in various organ systems. Pulmonary involvement seen in young adults is nearly always seen in the context of past or current cigarette smoking. Although it tends to be a single-system disease, extrapulmonary manifestations involving the skin, bone, and hypothalamic-pituitary-axis are possible. High resolution CT (HRCT) of the thorax findings includes centrilobular nodules and cysts that are bizarre in shape, variable in size, and thin-walled...

BACKGROUND: Pulmonary neuroendocrine tumors (NET) form a heterogeneous group of rare diseases. In these tumors, paraneoplastic syndromes have been described to drive the course of the disease, among them acromegaly induced by paraneoplastic secretion of growth hormone-releasing hormone (GHRH). CASE PRESENTATION: We report the case of a 43 years old patient initially diagnosed with acromegaly accompanied by weight gain and acral enlargement. Subsequently, further diagnostic work-up identified a solitary pulmonary neuroendocrine tumor (NET)...

The effectiveness and safety of fronto-basal interhemispheric approach in treating craniopharyngioma were evaluated. In this retrospective study, the safety and effectiveness of fronto-basal interhemispheric approach for surgical resection of craniopharyngioma in 20 patients was analyzed. Of the 20 patients, 12 were men and 8 were women, aged 15-65 years, with an average age of 42.5 years. The course of disease ranged from 1 to 36 months. The craniopharyngioma tumor was completely removed through surgical resection in 18 patients (90%) and partially removed in 2 patients...

  Liposteroid, a lipid emulsion containing dexamethasone, was developed in Japan. This drug is effective against rheumatoid arthritis, and has fewer side effects than dexamethasone. Moreover, at high dosage, liposteroid has been effectively used for the treatment of macrophage activation syndrome, because the lipid emulsions are easily taken up by phagocytes, and are retained in macrophages. Its anti-inflammatory effect was found to be 2-5 times higher than that of dexamethasone in arthritis and granuloma rat models...

OBJECTIVE: The syndrome of inappropriate antidiuresis (SIAD) is the commonest cause of hyponatraemia. Data on SIAD are mainly derived from retrospective studies, often with poor ascertainment of the minimum criteria for the correct diagnosis. Reliable data on the incidence of adrenal failure in SIAD are therefore unavailable. The aim of the study was to describe the aetiology of SIAD and in particular to define the prevalence of undiagnosed adrenal insufficiency. DESIGN: Prospective, single centre, noninterventional, observational study of patients admitted to Beaumont Hospital with euvolaemic hyponatraemia (plasma sodium ≤ 130 mmol/l) between January 1st and October 1st 2015...

Due to a high mortality rate, headshot injuries pose serious diagnostic and clinical problems. In this work, we wanted to describe four atypical headshot injuries. The first patient with a headshot injury using a nail gun mishap; the second one after a headshot injury, as a result of attempted murder (the bullet came to a parasagittal halt in the left parietal area); the third victim, after a suicide attempt (the bullet was removed from clivus area, below the pituitary gland); in the case of the fourth patient, after shooting himself with a self-constructed weapon in the chin, the metal body was surgically removed - a bearing pellet from the corpus callosum...

Metastases of solid tumors to the pituitary gland are often asymptomatic or appereas as with diabetes insipid us. Pituitary metastases more commonly affect the posterior lobe and the infundibulum than the anterior lobe. The presentation with an acute adrenal insufficiency is a rare event. A 69-year-old men presented with vomiting, low blood pressure and hypoglycemia. Hormonal exploration confirmed a hypopituitarism. Appropriate therapy was initiated urgently. The hypothalamic-pituitary MRI showed a pituitary hypertrophy, a nodular thickening of the pituitary stalk...

Inhaled pollutants produce effects in virtually all organ systems in our body and have been linked to chronic diseases including hypertension, atherosclerosis, Alzheimer's and diabetes. A neurohormonal stress response (referred to here as a systemic response produced by activation of the sympathetic nervous system and hypothalamus-pituitary-adrenal (HPA)-axis) has been implicated in a variety of psychological and physical stresses, which involves immune and metabolic homeostatic mechanisms affecting all organs in the body...

OBJECTIVE: Medical complications severely impair recovery of neurosurgical patients after craniotomy. The purpose of this study was to identify patients at risk of peri- and postoperative medical complications. Therefore, we present a large population of patients with different medical complications after elective craniotomy. METHODS: We retrospectively screened all patients who had been consecutively treated at our department between June 2009 and June 2014. Patients with any postoperative thromboembolic complication or pulmonary or systemic infection were compared with a control group without any medical complication...

Hyponatraemia is the most common electrolyte imbalance in neurosurgical patients. Acute hyponatraemia is particularly common in neurosurgical patients after any type of brain insult, including brain tumours and their treatment, pituitary surgery, subarachnoid haemorrhage or traumatic brain injury. Acute hyponatraemia is an emergency condition, as it leads to cerebral oedema due to passive osmotic movement of water from the hypotonic plasma to the relatively hypertonic brain which ultimately is the cause of the symptoms associated with hyponatraemia...

Cushing's syndrome is a state of cortisol excess, possibly from a tumor in the pituitary gland, the adrenal gland, or an ectopic nonpituitary ACTH-secreting source. The first form, pituitary in origin, was originally described by Harvey Cushing, MD, and was labeled as Cushing's disease. Long-term therapy with glucocorticoids also can lead to iatrogenic Cushing's syndrome.

BACKGROUND: Although the safety of topical nasal steroids is well established for nasal spray forms, data regarding the safety of steroid irrigations is limited. We studied the effect of long-term budesonide nasal irrigations (>6 months) on hypothalamic-pituitary-adrenal axis (HPAA) function and intraocular pressure (IOP) in patients post-endoscopic sinus surgery. METHODS: This was retrospective case series. Adrenal function was assessed by using the high-dose cosyntropin stimulation test...

Pulmonary lymphangioleiomyomatosis (LAM) is a rare lung disease caused by mutations in the tumor suppressor genes encoding Tuberous Sclerosis Complex (TSC) 1 and TSC2. The protein product of the TSC2 gene is a well-known suppressor of the mTOR pathway. Emerging evidence suggests that the pituitary hormone prolactin (Prl) has both endocrine and paracrine modes of action. Here, we have investigated components of the Prl system in models for LAM. In a TSC2 (+/-) mouse sarcoma cell line, down-regulation of TSC2 using siRNA resulted in increased levels of the Prl receptor...

Metastasis to the pituitary gland is an unusual situation in clinical practice, but the frequency thereof is increasing due to the increased survival of cancer patients, and greater availability of imaging. In most cases, they are found between the sixth and seventh decades of life, as determined in image examination of patients with known malignant neoplasm, but, generally, asymptomatic with respect to pituitary involvement. The most common primary sites are breast in women and lung in men. We present the case of a 64-year-old patient with clinical visual changes, polyuria, polydipsia, and decreased level of consciousness whose tests showed pan-hypopituitarism, hypernatremia and low urine specific gravity, and extensive mass in sellar region...

Vascular injury during lumbar spine surgery is a relatively rare complication but can have devastating outcomes. The injury may not be apparent during surgery and can present acutely or late in various manners, and some injuries can be asymptomatic. This report discusses the unusual case of a 35-year-old woman who underwent a right L4-5 microdiscectomy for disc herniation and 4 days postoperatively presented with a pulmonary embolus. A subsequent CT scan revealed a pseudoaneurysm and arteriovenous fistula of the right common iliac vein and artery, which gave rise to the embolus...

BACKGROUND: The chronic nature of tuberculosis and the protracted immuno-inflammatory reactions are implied in a series of metabolic and immune-endocrine changes accompanying the disease. We explored components from the hypothalamous-pituitary-gonadal axis and their relationship with cytokines involved in disease immunopathology, in male TB patients. METHODS: Plasma samples from 36 active untreated pulmonary TB male patients were used to determine TNF-α, IFN-γ, TGF-β, IL-6, cortisol, dehydroepiandrosterone, testosterone, progesterone, estradiol, luteinizing hormone (LH) and follicle-stimulating hormone (FSH) by ELISA...

The present paper reviews pharmacokinetics and systemic activity of a new patent of fluticasone fumarate/vilanterol trifenatate and summarises the efficacy data in children, adolescents and adults with asthma. Bioavailability of oral deposition of fluticasone furoate is approximately 1%, of oral and pulmonary deposition 15%. Fluticasone furoate 400, 600 and 800 µg have been associated with reductions in 24h urine cortisol excretion in adults, whereas several studies on fluticasone furoate/ vilanterol trifenatate 100/25 µg and 200/25 µg once daily found no suppressive effects...
