Evaluation of growth hormone deficiency in women with unexplained infertility.

Purpose: Growth hormone (GH) has been recognized to play a regulatory role in female reproduction. It has been reported that infertile GH deficient patients regained fertility after GH replacement. The frequency of GH deficiency is not established in patients diagnosed with unexplained infertility.

Alterations in Serum miR-126-3p Levels over Time: A Marker of Pituitary Insufficiency following Head Trauma.

Introduction: Traumatic brain injuries (TBIs) pose a high risk of pituitary insufficiency development in patients. We have previously reported alterations in miR-126-3p levels in sera from patients with TBI-induced pituitary deficiency.

Methods: To investigate why TBI-induced pituitary deficiency develops only in some patients and to reveal the relationship between miR-126-3p with hormone axes, we used mice that were epigenetically modified with miR-126-3p at the embryonic stage.

The Role of Apoptosis and Autophagy in the Hypothalamic-Pituitary-Adrenal (HPA) Axis after Traumatic Brain Injury (TBI).

Traumatic brain injury (TBI) is a major health problem affecting millions of people worldwide and leading to death or permanent damage. TBI affects the hypothalamic-pituitary-adrenal (HPA) axis either by primary injury to the hypothalamic-hypophyseal region or by secondary vascular damage, brain, and/or pituitary edema, vasospasm, and inflammation. Neuroendocrine dysfunctions after TBI have been clinically described in all hypothalamic-pituitary axes.

Prediabetes and mild hepatosteatosis are associated with blunted cortisol response to glucagon but not to growth hormone.

Background: Although there is a close relationship between cortisol and growth hormone (GH) levels, glucose intolerance and hepatosteatosis, changes in GH and the hypothalamo-pituitary-adrenal (HPA) axis were not previously studied in prediabetes. The main purpose of the present study was to assess changes in GH and HPA axis and their relationship with hepatosteatosis in prediabetic patients.

Methods: Forty prediabetic patients, with body-mass index (BMI) 25-35kg/m, and 23 healthy individuals, with normal glucose tolerance and similar age and BMI, were included.

Are thiol-disulfide homeostasis & neutrophil-to-lymphocyte ratio useful in the differential diagnosis of acute familial Mediterranean fever attacks & acute appendicitis?

Background & Objectives: Continuous subclinical inflammation can be seen in patients with familial Mediterranean fever (FMF) during the attack-free period. The importance of oxidative stress parameters in acute appendicitis (AA) progression has also been shown in previous studies. So, oxidative stress and the oxidant/antioxidant balance may play a role in this persistent subclinical inflammation.

Manual versus mechanical chest compression in in-hospital cardiac arrest: A retrospective cohort in emergency department patients.

Objective: Mechanical chest compression (CC) devices are frequently used in in-hospital and out-of-hospital settings. In this study, mechanical and manual CC in in-hospital cardiac arrest was compared in terms of survival.

Methods: Adult patients who were admitted to the emergency department (ED) for 2 years period and had cardiac arrest in the ED were included in this retrospective, observational study.

Approaches of Emergency Department Physicians to Pediatric Burns: A Survey Assessment.

Burned children generally arrive at emergency departments before referring to specialized burn centers. Their initial treatments are performed by non-burn doctors who work in emergency departments. The aim of this study was to evaluate emergency department doctors' knowledge regarding the initial interventions and transfer of pediatric burn patients.

The Characterization of Sex Differences in Hypoglycemia-Induced Activation of HPA Axis on the Transcriptomic Level.

Activation of the hypothalamic-pituitary-adrenal (HPA) axis using an insulin tolerance test (ITT) is a medical diagnostic procedure that is frequently used in humans to assess the HPA and growth-hormone (GH) axes. Whether sex differences exist in the response to ITT stress is unknown. Thus, investigations into the analysis of transcripts during activation of the HPA axis in response to hypoglycemia have revealed the underlying influences of sex in signaling pathways that stimulate the HPA axis.

Comparison of thiol/disulphide homeostasis with modified Alvarado and RIPASA scores in the diagnosis of acute appendicitis.

Background: This study aims to investigate the role of thiol/disulfide homeostasis parameters in the diagnosis of acute appendicitis and to determine whether it is beneficial to use these parameters in combination with the modified Alvarado and RIPASA scoring systems.

Methods: This study was prospectively carried out on 265 patients who presented to the emergency department with the complaint of right lower quadrant pain between 01.07.

Is biochemical hypoglycemia necessary during an insulin tolerance test?

Objective The insulin tolerance test (ITT) has been accepted as the gold standard test for assessing the integrity of the growth hormone (GH) - insulin-like growth factor (IGF-1) axis and the hypothalamic-pituitary-adrenal (HPA) axis. The goal of the test is to achieve clinical and biochemical hypoglycemia at a blood glucose level ≤ 40 mg/dL to effectively and correctly assess the HPA and GH-IGF-1 axes. In this study, the GH and cortisol responses of patients who achieved and failed to achieve biochemical hypoglycemia during an ITT were compared.

Long-term neuroendocrine consequences of traumatic brain injury and strategies for management.

: Traumatic brain injuries (TBI) are reported to cause neuroendocrine impairment with a prevalence of 15% with confirmatory testing. Pituitary dysfunction (PD) may have detrimental effects on vital parameters as well as on body composition, cardiovascular functions, cognition, and quality of life. Therefore, much effort has been made to identify predictive factors for post-TBI PD and various screening strategies have been offered.

Tissue adhesives to secure peripheral intravenous catheters: A randomized controlled trial in patients over 65 years.

Introduction: Peripheral venous catheterization is one of the most used medical procedures in hospitals worldwide. Recent researches state that using intravascular devices is a risk factor for both local and systemic complications. In this study, we aimed to test that addition of tissue adhesive to the insertion site of peripheral intravenous catheters (PIVC) in the emergency department (ED) would reduce the device failure rate at 6 h and 24 h following insertion.

Pituitary dysfunction due to sports-related traumatic brain injury.

Purpose: After 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.

Association Between Magnesium Status, Dietary Magnesium Intake, and Metabolic Control in Patients with Type 2 Diabetes Mellitus.

Background: Hypomagnesemia could worsen glycemic control by impairing insulin release and promoting insulin resistance. On the contrary, type 2 diabetes mellitus (T2DM) may induce and/or exacerbate low serum magnesium levels, and this could, in turn, worsen glycemic control of diabetes.

Objective: The aim of this study was to investigate the relationship between serum magnesium level, dietary magnesium intake, and metabolic control parameters in patients with T2DM.

Sports-Related Repetitive Traumatic Brain Injury: A Novel Cause of Pituitary Dysfunction.

Traumatic brain injury (TBI) is one of the major causes of disability and death, particularly in the young population. Recent clinical studies have demonstrated that TBI-induced pituitary dysfunction occurs more frequently than previously estimated, and this may contribute to delayed diagnosis and treatment of hormonal abnormalities. Today, the popularity of combative sports increases, and athletes who deal with these sports have risks of developing hypopituitarism attributed to repetitive TBIs.

Patients with papillary thyroid carcinoma associated with high stimulated serum calcitonin levels.

Unlabelled: Among various substances produced by C-cells, the most important one is calcitonin (CT) that is used for detection, post-operative follow-up and evaluation of individuals at risk of developing medullary thyroid carcinoma (MTC). However, the role of serum CT measurement in the evaluation of thyroid nodules has been widely discussed, and there is still no consensus about the role of CT in the initial evaluation of all thyroid nodules. Two patients with thyroid nodules whose fine-needle aspiration results were compatible with benign cytology besides having mildly elevated basal serum calcitonin levels were reported.

Transient vocal cord paralysis following central venous hemodialysis catheter insertion.

In this article, we present a case of recurrent laryngeal nerve palsy not caused by nerve injury but due to local anesthetic infiltration that was applied prior to central venous catheterization. A 47-year-old female patient was admitted to emergency room with fatigue and nausea and was diagnosed with acute renal failure. Right jugular venous catheterization was performed for emergency hemodialysis with Seldinger technique using middle approach.

Circulating MicroRNAs as Potential Biomarkers for Traumatic Brain Injury-Induced Hypopituitarism.

Traumatic brain injury (TBI), a worldwide public health problem, has recently been recognized as a common cause of pituitary dysfunction. Circulating microRNAs (miRNAs) present in the sera are characteristically altered in many pathological conditions and have been used as diagnostic markers for specific diseases. It is with this goal that we planned to study miRNA expression in patients with TBI-induced hypopituitarism.

Can a glucagon stimulation test characterized by lower GH cut-off value be used for the diagnosis of growth hormone deficiency in adults?

Objective: The aim of this study was to assess diagnostic values of insulin tolerance test (ITT), glucagon stimulation test (GST), and insulin like growth factor-I (IGF-I) level, to find optimal GH cut-off values for GST, and to evaluate efficiencies of patient age, gender, body-mass index (BMI), and additional pituitary hormone deficiencies (PHDs) in the diagnosis of growth hormone deficiency (GHD).

Study Design: This retrospective study involved 216 patients with a pituitary disease and 26 healthy controls. Age, gender, BMI, medical histories, and hormonal data including baseline and stimulated hormone values were evaluated.

The lucky patient who aspirated a needle.

Foreign body aspiration is seen frequently in pediatric and geriatric patients, but it can also be seen in adults. Needle aspiration is a common problem in our country. Foreign body aspiration can lead to complete airway obstruction, asphyxia and death but sometimes symptoms may not be evident during the early period of aspiration and patients may present with complications afterwards.

GH and Pituitary Hormone Alterations After Traumatic Brain Injury.

Traumatic brain injury (TBI) is a crucially important public health problem around the world, which gives rise to increased mortality and is the leading cause of physical and psychological disability in young adults, in particular. Pituitary dysfunction due to TBI was first described 95 years ago. However, until recently, only a few papers have been published in the literature and for this reason, TBI-induced hypopituitarism has been neglected for a long time.
