The mobile phase additive (DMSO) has been described as a useful tool to enhance electrospray ionization (ESI) of peptides and proteins. So far, this technique has mainly been used in proteomic/peptide research, and its applicability in a routine clinical laboratory setting (i.e., doping control analysis) has not been described yet. This work provides a simple, easy to implement screening method for the detection of doping relevant small peptides (GHRPs, GnRHs, GHS, and vasopressin-analogues) with molecular weight less than 2 kDa applying DMSO in the mobile phase...

We report a 27-year-old pregnant woman with polyuria, polydipsia and headache in the third trimester of pregnancy. Hypernatremia (153 mEq/L), high plasma osmolality (300 mOsm/kgH2O) and low urinary osmolality (92 mOsm/kgH2O) were observed at the admission to our hospital. Plasma arginine vasopressin (AVP) level was inappropriately low (2.2 pg/mL) compared to the high plasma osmolality. Plasma AVP responses to hypertonic-saline infusion were blunted, and her urine osmolality increased in response to desmopressin...

Intracranial epidermoid cysts are benign lesions of epithelial origin that most frequently present with symptoms of mass effect. Although they are often associated with a high rate of residual tumor and recurrence, maximal safe resection usually leads to good outcomes. The authors report a complete resection of an uncommon pituitary stalk epidermoid cyst with intrasellar extension using a combined suprasellar and infrasellar interpituitary, endoscopic endonasal transsphenoidal approach. The patient, a 54-year-old woman, presented with headache, visual disturbance, and diabetes insipidus...

Desmopressin (DDAVP), a synthetic analog of vasopressin, has been used in patients with von Willebrand disease (VWD), mild hemophilia A, and platelet dysfunction to reduce the risk of bleeding associated with surgical and interventional procedures. We report the case of a patient with VWD presenting with a bulging disc and radicular pain that underwent transforaminal epidural steroid injections. Her course was complicated with the interval development of headaches and dizziness symptomatic of moderate hyponatremia, likely due to excessive fluid intake...

Excessive bleeding at surgery is a feared complication in patients with inherited platelet disorders (IPD), however very few studies have evaluated the frequency of surgical bleeding in these hemorrhagic disorders. We performed a multicentric, retrospective worldwide study to assess the bleeding complications of surgery, the preventive and therapeutic approaches adopted and their efficacy in patients with IPDs by rating the outcome of 829 surgical procedures carried out in 423 patients with well defined forms of IPD (238 inherited platelet function disorders -IPFD- and 185 inherited platelet number disorders-IPND-)...

A 38-year-old Japanese man who had undergone clipping surgery for a ruptured aneurysm of the anterior communicating artery 2 days prior, suddenly developed refractory hypernatremia (serum sodium (Na) 156 - 162 mmol/L). Symptoms included low plasma vasopressin, fluctuating urine osmolality (120 - 710 mOsm/kg) and lack of thirst, all suggesting adipsic diabetes insipidus (ADI). Hypernatremia was corrected by scheduled water intake with desmopressin administration. During 1-year follow-up after the surgery, his serum Na level normalized despite the suspension of desmopressin, but neither thirst nor osmolality-dependent vasopressin release recovered...

Non-vitamin K antagonist oral anticoagulants (NOACs) are effective at preventing stroke in patients with atrial fibrillation (AF). However, little is known about the management of bleeding in contemporary, clinical use of NOACs. We aimed to assess the frequency, management, and outcomes of major bleeding in the setting of community use of NOACs. Using the Outcomes Registry for Better Informed Treatment of Atrial Fibrillation II registry, we analyzed rates of International Society on Thrombosis and Haemostasis major bleeding and subsequent outcomes in patients treated with NOACs versus warfarin...

One of the most common risks after a heart transplant is bleeding. In this study, the effect of desmopressin administration on the amount of bleeding and transfusion requirements following heart transplant surgery was investigated. In a double-blind clinical trial, 48 patients who were candidates for heart transplant surgery were randomly assigned to two groups. In the intervention group, patients received desmopressin 0.3 μg/kg, 30 min. before surgery. Patients in the control group received normal saline at the same amount and time...

von Willebrand disease (VWD) is caused by quantitative or qualitative defects in von Willebrand factor (VWF). The mainstay of therapy is desmopressin, which is, however, not useful in certain forms of VWD notwithstanding adverse events. For these patients, plasma-derived factor VIII (pdFVIII)/VWF concentrates have been available for close to three decades but have a theoretical risk of disease transmission, hypersensitivity/allergic reactions, inhibitors and thrombosis. A recombinant VWF (vonicog alfa, Vonvendi™; manufactured by Baxalta, now part of Shire) was approved by the U...

This review aims at summarizing essential aspects of epidemiology and pathophysiology of hyponatremia in chronic heart failure (CHF), to set the ground for a practical as well as evidence-based approach to treatment. As a guide through the discussion of the available evidence, a clinical case of hyponatremia associated with CHF is presented. For this case, the severe neurological signs at presentation justified an emergency treatment with hypertonic saline plus furosemide, as indicated. Subsequently, as the neurological emergency began to subside, the reversion of the trend toward hyponatremia overcorrection was realized by continuous infusion of hypotonic solutions, and administration of desmopressin, so as to prevent the very feared risk of an osmotic demyelination syndrome...

RATIONALE: Lymphocytic hypophysitis is a relatively rare autoimmune disease defined by lymphocytic infiltration to the pituitary. Its rarity and wide spectrum of clinical manifestations make clarification of the pathology difficult. Here, we describe a case we examined from the primary diagnosis to final discharge, showing the serial progression of lymphocytic infundibuloneurohypophysitis (LINH) to panhypopituitarism with extrapituitary inflammatory invasion in a short period, and responding favorably to high-dose glucocorticoid treatment...

BACKGROUND: Hypophysitis is an umbrella term for a group of disorders involving inflammation of the pituitary gland. A rare occurrence in humans, hypophysitis can produce a range of clinical signs including (but not limited to) visual deficits and diabetes insipidus. Only five cases of canine hypophysitis exist in the literature, all presenting in mature dogs with no visual deficits and a grave outcome. This case report describes the clinical and advanced imaging features of blindness-inducing presumptive hypophysitis in a dog, which rapidly resolved with medical management...
