    Adrenocortical insufficiency may arise through primary failure of the adrenal glands or due to lack of ACTH stimulation as a result of pituitary or hypothalamic dysfunction. Prolonged administration of exogenous steroids will suppress the hypothalamic-pituitary-adrenal axis, and hence cortisol secretion. We review briefly the causes, investigation, and treatment of adrenal insufficiency, and highlight aspects of particular relevance to patients with adrenal tumors.

    Primary adrenal insufficiency is a non frequent disease, that is declared in young adults and in the most of the cases is produced from an autoimmune mechanism or a tuberculous disease. The incidence of these forms in the different geographic areas is dependent of degree of irradication of the tuberculosis. We report the case of a patient with latent chronic adrenal insufficiency of tuberculous origin who was affected for an addisonian crisis during an intercurrent infectious disease, which permitted the diagnosis of the addisonian crisis, and Mal of Pott was moreover detected. Evolution with corticosteroid and specific treatment was very favorable.

    Adrenal insufficiency is a disorder characterized by hypoactive adrenal glands resulting in insufficient production of the hormones cortisol and aldosterone by the adrenal cortex. This disorder may develop as a primary failure of the adrenal cortex or be secondary to an abnormality of the hypothalamic-pituitary axis. Patients with adrenal insufficiency often are asymptomatic or they may present with fatigue, muscle weakness, weight loss, low blood pressure, and sometimes darkening of the skin. The presentation of adrenal insufficiency varies dramatically and poses a major diagnostic dilemma. This review focuses on the diagnosis and treatment of primary and secondary adrenal insufficiency.

    Full Text Available Introduction: Tuberculosis is the most common cause of Addison′s disease in India. The exact status of adrenal reserve in tuberculosis is still an enigma and recovery of adrenal function is unpredictable. Objective: We report a case with a pre-Addisonian state and unchanged adrenal size after 1 year treatment. Materials and Methods: A 31-year patient with adrenal tuberculosis was diagnosed and treated with anti tubercular drugs (ATDs and steroid. Results: A 31-year male, presented with fever and weight loss for 3½ months with anorexia, nausea, hyperpigmentation of skin, and buccal mucosa and weakness with past h/o adequately treated pulmonary tuberculosis at 3 years of age. On examination, the patient was anemic. A non-tender, firm right (Rt. submandibular lymphnode was palpable. Investigations revealed: High erythrocyte sedimentation rate (ESR, negative HIV, and sputum for acid fast bacilli (AFB. Initial cortisol was high but subsequently became low with negative short synacthin test (SST. Computed tomography showed bilateral (B/L enlarged hypodense adrenal mass with inconclusive fine needle aspiration cytology (FNAC and negative AFB culture. Rt. submandibular lymph node FNAC showed caseating granuloma. ATDs and steroids were started, the lymphadenopathy regressed and symptoms subsided. However, after 1 year of treatment steroid withdrawal failed and adrenal size remained the same. Conclusion: The adrenal has considerable capacity to regenerate during active infection and ultimately become normal or smaller in size. However, in the case reported here, they failed to regress. Reversal of adrenal function following ATD is a controversial issue. Some studies have shown normalization following therapy, while others have contradicted it similar to the finding in our case.

    Relative adrenal insufficiency (RAI) is a common finding in cirrhotic patients with severe sepsis, and increased mortality. Its significance is unknown in stable conditions. The aim of this study was to evaluate the prevalence of RAI in stable cirrhotic patients at different stages of the disease. Also, the impact of RAI on the survival was evaluated and basal cortisol levels between plasma and saliva was correlated in control subjects and cirrhotic patients. Forty seven ambulatory patients and 16 control subjects were studied. RAI was defined as a serum cortisol increase of less than 9 υg/dl from baseline after the stimulation with 250 mg of synthetic ACTH. Twenty two had Child-Pugh = 8 and 25 = 9. The prevalence of RAI in patients with stable cirrhosis was 22%. A higher incidence of RAI was observed in patients with a Child-Pugh = 9 (8/32) than in those with = 8 (3/13, p developed this complication (79% and 51%, p < 0.05, respectively). In summary, the prevalence of RAI is frequent in patients with stable cirrhosis and that it is related to the severity of liver diseaseand increased mortality. PMID:27576278

    Adrenal insufficiency continues to be a challenge for patients, their physicians, and researchers. During the past decade, long-term studies have shown increased mortality and morbidity and impaired quality of life in patients with adrenal insufficiency. These findings might, at least partially, be due to the failure of glucocorticoid replacement therapy to closely resemble physiological diurnal secretion of cortisol. The potential effect of newly developed glucocorticoid drugs is a focus of research, as are the mechanisms potentially underlying increased morbidity and mortality. Adrenal crisis remains a threat to lives, and awareness and preventative measures now receive increasing attention. Awareness should be raised in medical teams and patients about adrenal insufficiency and management of adrenal crisis to improve clinical outcome.

    2013-06-01

    Adrenal insufficiency may be caused by the destruction or altered function of the adrenal gland with a primary deficit in cortisol secretion (primary adrenal insufficiency) or by hypothalamic-pituitary pathologies determining a deficit of ACTH (secondary adrenal insufficiency). The clinical picture is determined by the glucocorticoid deficit, which may in some conditions be accompanied by a deficit of mineralcorticoids and adrenal androgens. The substitutive treatment is aimed at reducing the signs and symptoms of the disease as well as at preventing the development of an addisonian crisis, a clinical emergency characterized by hypovolemic shock. The oral substitutive treatment should attempt at mimicking the normal circadian profile of cortisol secretion, by using the lower possible doses able to guarantee an adequate quality of life to patients. The currently available hydrocortisone or cortisone acetate preparations do not allow an accurate reproduction of the physiological secretion pattern of cortisol. A novel dual-release formulation of hydrocortisone, recently approved by EMEA, represents an advancement in the optimization of the clinical management of patients with adrenal insufficiency. Future clinical trials of immunomodulation or immunoprevention will test the possibility to delay (or prevent) the autoimmune destruction of the adrenal gland in autoimmune Addison's disease.

    Full Text Available Opioids have been the mainstay for pain relief and palliation over a long period of time. They are commonly abused by drug addicts and such dependence usually imparts severe physiologic effects on multiple organ systems. The negative impact of opioids on the endocrine system is poorly understood and often underestimated. We describe a patient who developed severe suppression of the hypothalamic-pituitary adrenal (HPA axis leading to secondary adrenal insufficiency due to long standing abuse of opioids.

    Full Text Available Adrenal insufficiency is caused by either primary adrenal failure or by hypothalamic-pituitary impairment of the corticotropic axis. Adrenal insufficiency, first codified in 1855 by Thomas Addison, remains relevant in 2014 because of its lethal nature. Though, it is a rare disease but is life threatening when overlooked. Main presenting symptoms such as fatigue, anorexia and weight loss are nonspecific, thus diagnosis is often delayed. The diagnostic work-up is well established but some pitfalls remain. The diagnosis is adequately established by the 250 μg ACTH (adrenocorticotropic hormone stimulation test in most cases. Glucocorticoids provide life saving treatment but long-term quality of life is impaired, perhaps because therapy is not given in a physiologic way. Dehydroepiandrosterone-replacement therapy has been introduced that could help to restore quality of life. It may be useful in pubertal girls, but not in adults. Monitoring of glucocorticoid-replacement is difficult due to lack of objective methods of assessment and is therefore largely based on clinical grounds. Thus, long-term management of patients with adrenal insufficiency remains a challenge, requiring an experienced specialist.

    Allgrove syndrome or triple-Asyndrome is a rare familial multisystem autosomal recessive disorder. It is characterised by triad of alacrima, achalasia and adrenal insufficiency due to adrenocorticotropin hormone (ACTH) resistance. If it is associated with autonomic dysfunction, it is termed as 4-Asyndrome. This syndrome is caused by a mutation in the Achalasia - Addisonism - Alacrima (AAAS) gene on chromosome 12q13 encoding the nuclear pore protein ALADIN. A5-year boy presented with history of fits and altered sensorium for one day. He also had increased pigmentation of body and persistent vomiting since six months of age. Laboratory investigations and imaging revealed alacrimia, achalasia and adrenal insufficiency due to ACTH resistance. He had episodes of hypertensive crises, for which he was thoroughly investigated and it was found to be due to autonomic instability. Based on clinical findings and investigations he was diagnosed as case of Allgrove syndrome or 4-Asyndrome with autonomic dysfunction. PMID:27671188

    Adrenal insufficiency (AI) is a rare endocrine disease, associated to increased mortality if left untreated. It can be due to a primary failure of the adrenal glands (primary AI) or malfunctioning of the hypothalamic-pituitary-adrenal axis (HPA) (secondary AI). The lack of data on incidence/prevalence of adrenal insufficiency in Spain complicates any evaluation of the magnitude of the problem in our country. Initial symptoms are non-specific, so often there is a delay in diagnosis. Current therapy with available glucocorticoids is associated with decreased quality of life in patients with treated AI, as well as with increased mortality and morbidity, probably related to both over-treatment and lack of hydrocortisone, associated with non-physiological peaks and troughs of the drug over the 24 hours. The availability of a new drug with a modified dual release (immediate and retarded), that requires one only daily dose, improves and simplifies the treatment, increases compliance as well as quality of life, morbidity and possibly mortality. This revision deals with the knowledge on the situation both globally and in Spain, prior to the availability of this new drug.

    Adrenal reserve depletion and overstimulation of thehypothalamus-pituitary-adrenal (HPA) axis are causesfor adrenal insufficiency (AI) in critically ill individuals.Cirrhosis is a predisposing condition for AI in cirrhotics aswell. Both stable cirrhotics and liver transplant patients(early and later after transplantation) have been reportedto present AI. The mechanisms leading to reducedcortisol production in cirrhotics are the combination oflow cholesterol levels (the primary source of cortisol), theincreased cytokines production that overstimulate andexhaust HPA axis and the destruction of adrenal glandsdue to coagulopathy. AI has been recorded in 10%-82%cirrhotics depending on the test used to evaluate adrenalfunction and in 9%-83% stable cirrhotics. The similarityof those proportions support the assumption that AI isan endogenous characteristic of liver disease. However,the lack of a gold standard method for AI assessmentand the limitation of precise thresholds in cirrhoticsmake difficult the recording of the real prevalence of AI.This review aims to summarize the present data overAI in stable, critically ill cirrhotics and liver transplantrecipients. Moreover, it provides information about thecurrent knowledge in the used diagnostic tools and thepossible effectiveness of corticosteroids administration incritically ill cirrhotics with AI.

    The contralateral healthy adrenal in patients undergoing unilateral adrenalectomy for Cushing's is known to be suppressed temporarily and forms the basis of peri and postoperative steroids. We present four cases of Cushing's who had prolonged adrenal insufficiency with continued requirement for steroids for periods ranging 1-4 years after unilateral adrenalectomy for Cushing's. We further review literature regarding the recovery of the hypothalamo pituitary adrenal axis postsurgery in patients with Cushing's syndrome.

    The endocrine disorder adrenal insufficiency includes inadequate production of the steroid hormone cortisol. This results in poor physiological responses to illness, trauma or other stressors and risk of adrenal crisis. Management is based on administration of hydrocortisone. It is important to avoid under- or over-treatment and increase the dosage during times of physiological stress. To reduce morbidity, hospital admissions and mortality, the education and empowerment of parents and carers, and prompt intervention when necessary are essential. A steroid therapy card for adrenal insufficiency containing personal information on a patient\\'s condition was developed for use by families and their specialist centres.

    Intramuscular endocrine gland transplantation has been well described as it pertains to parathyroid autotransplantation; however, transplantation of the adrenal gland is less well characterized. While adrenal autotransplantation in the setting of Cushing's disease has been described, intramuscular adrenal allotransplantation as a cure for adrenal insufficiency to our knowledge has not been previously carried out. Current treatment for adrenal insufficiency leaves patients without diurnal variation in cortisol release and susceptible to the detrimental effects of chronic hypercortisolism. We describe here the case of a 5-year-old girl with renal failure who had adrenal insufficiency following fulminant meningococcemia that led to requirements for both stress-dose steroid and mineralocorticoid replacement. Ten months after the onset of her disease, she received a simultaneous renal and adrenal gland transplant from her mother. The adrenal gland allograft was morselized into 1 mm(3) segments and implanted into three 2 cm pockets created in her rectus abdominis muscle. Three years after surgery, her allograft remains fully functional, responding well to adrenocorticotropin hormone stimulation and the patient does not require any steroid or mineral-corticoid supplementation. We believe this case represents the first description of successful functional intramuscular adrenal allograft transplantation with long-term follow up as a cure for adrenal insufficiency.

    We describe a case of severe psychotic disorder as the only manifestation of primary adrenal insufficiency. A 63-year-old man presented with psychotic symptoms without any prior psychiatric history. During the clinical and laboratorial investigation, exams revealed a normovolemic hyponatremia. The patient showed no other clinical signs or symptoms compatible with adrenal insufficiency but displayed very high ACTH and low serum cortisol concentrations. Brain magnetic resonance imaging showed no significant changes, including the pituitary gland. The patient was initially treated with intravenous corticosteroids, resulting in rapid remission of the psychotic symptoms. The association between adrenal insufficiency and neuropsychiatric symptoms is rare but these symptoms can often be the first clinical presentation of the disease. PMID:25954562

    Full Text Available Secondary involvement of the adrenal gland with non-Hodgkin’s lymphoma has been reported to occur in up to 25% of patients during the course of the disease. A 45-year-old man presented with a several month history of nausea, fatigue and weight loss. His medical history was unremarkable. Abdominal computed tomography (CT was performed and showed bilateral adrenal massive masses measuring 10x7.5 cm on the left and 4.8x4 cm on the right. He developed adrenal insufficiency in the follow-up period. The patient was started on replacement dose of prednisolone. A positron emission tomography-CT scan was acquired for further staging of the disease and showed intense fluorodeoxyglucose accumulation in both adrenal glands, additionally a slight fluorodeoxyglucose accumulation was observed in the ileocecal site. He did not accept adrenal biopsy or surgery. Histopathological examination of the ileocecal site revealed diffuse large B-cell lymphoma. He was administered rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy. Bilateral adrenal lymphoma is a rare entity when compared with the incidence of adenoma and adrenal metastases of other cancers. Adrenal insufficiency may be the primary symptom of presentation, especially with bilateral involvement as in bilateral adrenal lymphoma.

    2015-09-01

    Full Text Available Primary adrenal insufficiency is defined by the impaired synthesis of adrenocortical hormones due to an intrinsic disease of the adrenal cortex. Determining its etiology is crucial to allow adequate long-term management and genetic counseling. We report the case of a male adolescent that presented in the neonatal period with adrenal crisis and received replacement therapy for primary adrenal insufficiency. During follow-up, adrenal hypoplasia congenita (AHC was suspected given his persistently raised adrenocorticotropic hormone levels, with markedly low 17-OH progesterone and androstenedione levels. DNA sequence analysis revealed a mutation in NR0B1 gene (c.1292delG, confirming the diagnosis. Delayed puberty and persistent low levels of gonadotropins led to testosterone replacement therapy. X-linked AHC is a rare cause of primary adrenal insufficiency and hypogonadotropic hypogonadism, related to mutations in NR0B1 gene. Despite its rarity, AHC should be considered in patients who present with primary adrenal failure, low levels of 17-OH progesterone and hypogonadotropic hypogonadism.

    Full Text Available Delay of diagnosis of primary adrenal insufficiency (PAI leads to adrenal crisis which is potentially lethal complication. The objective of our work was an assessment whether the establishment of diagnosis of adrenocortical insufficiency in Poland is so much delayed as assessed in the past. We have analysed data from 60 patients with diagnosis of PAI established in our department during the past 12 years and who are still under our care. We found that the time to diagnosis of primary adrenal insufficiency in Poland exceeds 3 months in every patient and 6 months in patients admitted with symptoms of adrenal crisis. Forty-four percent of patients were diagnosed only just after the hospitalisation due to crisis, despite the evident signs and symptoms of PAI. Lack of appetite and loss of body weight occurred in all patients and for that reason a diagnosis of chronic gastric and duodenal ulcer disease was the most often incorrect diagnosis. After the proper diagnosis and treatment, in the course of 1–11 years of observation, there was only 6 imminent adrenal crises in 5 patients. Our results indicated that training of primary care physicians in the field of recognising and treatment of adrenal insufficiency is still essential.

  7. Mifepristone Accelerates HPA Axis Recovery in Secondary Adrenal Insufficiency

    2016-01-01

    Context. Transient secondary adrenal insufficiency (SAI) is an expected complication following successful adenomectomy of ACTH-secreting pituitary adenomas or unilateral adrenalectomy for cortisol-secreting adrenal adenomas. To date, no pharmacological therapy has been shown to hasten recovery of the hypothalamic-pituitary-adrenal (HPA) axis in this clinical scenario. Case Description. A 33-year-old woman underwent uncomplicated unilateral adrenalectomy for a 3.7 cm cortisol-secreting adrenal adenoma. Postoperatively, she developed SAI and was placed on hydrocortisone 15 mg/day, given in divided doses. In the ensuing six years, the patient's HPA axis failed to recover and she remained corticosteroid-dependent. Quarterly biochemical testing (after withholding hydrocortisone for 18 hours) consistently yielded undetectable serum cortisol and subnormal plasma ACTH levels. While she was on hydrocortisone 15 mg/day, mifepristone was initiated and gradually titrated to a maintenance dose of 600 mg/day after 5 months. Rapid recovery of the HPA axis was subsequently noted with ACTH rising into the supranormal range at 4 months followed by a subsequent rise in cortisol levels into the normal range. After 6 months, the dose of hydrocortisone and mifepristone was lowered and both were ultimately stopped after 8 months. The HPA axis remains normal after an additional 16 months of follow-up. Conclusion. Mifepristone successfully restored the HPA axis in a woman with prolonged secondary adrenal insufficiency (SAI) after adrenalectomy for Cushing's syndrome (CS). PMID:27516913

    Failure to thrive in an elderly patient is often attributed to depression, especially when a patient does not have any chronic diseases or if there is no apparent medical reason to justify poor appetite, cachexia and generalized weakness. Hyponatremia often occurs in such patients and a thorough evaluation as to its etiology should be sought before committing to a premature diagnosis, which at the time may seem more plausible. We report a patient who presented with depression, weight loss and persistent hyponatremia, evaluation of which revealed the cause to be due to secondary adrenal insufficiency, which when treated, resulted in resolution of the symptom complex. Therefore, in our case report, we elucidate the importance of pursuing further evaluation to rule out adrenal insufficiency as a medical cause of depression, especially in the presence of hyponatremia, which is often overlooked and is generally attributed to dehydration in the setting of failure to thrive or SIADH in patients who are on psychotropic medications.

    Mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) are established subgroups of mitochondrial encephalomyopathy. m.3243A>G a common point mutation is detected in tRNA in majority of patients with MELAS phenotype whereas m.8344A>G point mutation in tRNA is observed, in MERRF phenotype. Adrenal insufficiency has not been reported in mitochondrial disease, except in Kearns-Sayre Syndrome (KSS), which is a mitochondrial deletion syndrome. We report an unusual presentation in a five year old boy who presented with clinical phenotype of MELAS and was found to have m.8344A>G mutation in tRNA. Addison disease was identified due to hyperpigmentation of lips and gums present from early childhood. This is the first report describing adrenal insufficiency in a child with MELAS phenotype.

    As one kind of infectious diseases of adrenal gland, adrenal tuberculosis can result in a life-threatening disorder which is called primary adrenal insufficiency(PAI) due to the destruction of adrenal cortex. Computed tomography(CT) and magnetic resonance imaging(MRI) play significant roles in the diagnosis of this etiology of PAI based on the CT and MRI appearances of the adrenal lesions. In this mini-review, we intend to study the CT and MRI features of adrenal tuberculosis, which could be helpful to both endocrinologist and radiologist to establish a definitive diagnosis for adrenal tuberculosis resulting in PAI.

    Megestrol acetate (MA) is a synthetic progestin with both antineoplastic and orexigenic properties. In addition to its effects on the progesterone receptor, MA also binds the glucocorticoid receptor. Some patients receiving MA therapy have been reported to develop clinical features of glucocorticoid excess, while others have experienced the clinical syndrome of cortisol deficiency-either following withdrawal of MA therapy or during active treatment. We describe a patient who presented with clinical and biochemical features of central adrenal insufficiency. Pituitary function was otherwise essentially normal, and the etiology of the isolated ACTH suppression was initially unclear. The use of an exogenous glucocorticoid was suspected but was initially denied by the patient; ultimately, the culprit medication was uncovered when a synthetic steroid screen revealed the presence of MA. The patient's symptoms improved after she was switched to hydrocortisone. Clinicians should be aware of the potential effects of MA on the hypothalamic-pituitary-adrenal (HPA) axis. PMID:26770843

  16. Update on adrenal insufficiency in patients with liver cirrhosis.

    Liver cirrhosis is a major cause of mortality worldwide, often with severe sepsis as the terminal event. Over the last two decades, several studies have reported that in septic patients the adrenal glands respond inappropriately to stimulation, and that the treatment with corticosteroids decreases mortality in such patients. Both cirrhosis and septic shock share many hemodynamic abnormalities such as hyperdynamic circulatory failure, decreased peripheral vascular resistance, increased cardiac output, hypo-responsiveness to vasopressors, increased levels of proinflammatory cytokines [interleukine(IL)-1, IL-6, tumor necrosis factor-alpha] and it has, consequently, been reported that adrenal insufficiency (AI) is common in critically ill cirrhotic patients. AI may also be present in patients with stable cirrhosis without sepsis and in those undergoing liver transplantation. The term hepato-adrenal syndrome defines AI in patients with advanced liver disease with sepsis and/or other complications, and it suggests that it could be a feature of liver disease per se, with a different pathogenesis from that of septic shock. Relative AI is the term given to inadequate cortisol response to stress. More recently, another term is used, namely "critical illness related corticosteroid insufficiency" to define "an inadequate cellular corticosteroid activity for the severity of the patient's illness". The mechanisms of AI in liver cirrhosis are not completely understood, although decreased levels of high-density lipoprotein cholesterol and high levels of proinflammatory cytokines and circulatory endotoxin have been suggested. The prevalence of AI in cirrhotic patients varies widely according to the stage of the liver disease (compensated or decompensated, with or without sepsis), the diagnostic criteria defining AI and the methodology used. The effects of corticosteroid therapy on cirrhotic patients with septic shock and AI are controversial. This review aims to summarize the

    Full Text Available Adrenal insufficiency is a life-threatening event, so it is recommended for patients with known adrenal insufficiency to be properly educated regarding sick-day management. In the month of Ramadan, people refrain from eating and drinking during daylight hours. It is very important for patients with adrenal insufficiency, who wish to keep a fast, to be well aware of the disease, the suitable drug to be used for that particular period, warning signs, sick-day management, physical activity, and dietary limits. This article describes guidelines for the sick-day management of patients with adrenal insufficiency, in the month of Ramadan.

    Adrenal crisis is a life-threatening emergency that causes significant excess mortality in patients with adrenal insufficiency. Delayed recognition by medical staff of an impending adrenal crisis and failure to give timely hydrocortisone therapy within the emergency department continue to be commonly encountered, even in metropolitan teaching hospitals. Within the authors' institutions, several cases of poorly handled adrenal crises have occurred over the last 2 years. Anecdotal accounts from members of the Addison's support group suggest that these issues are common in Australia. This manuscript is a timely reminder for clinical staff on the critical importance of the recognition, treatment and prevention of adrenal crisis. The manuscript: (i) outlines a case and the clinical outcome of sub-optimally managed adrenal crisis, (ii) summarises the clinical features and acute management of adrenal crisis, (iii) provides recommendations on the prevention of adrenal crisis and (iv) provides guidance on the management of 'sick days' in patients with adrenal insufficiency.

    2010-01-01

    Adrenal gland insufficiency - the clinical manifestation of deficient production or action of adrenal steroids - is a life-threatening disorder. Among many factors which can predispose to primary adrenal failure, an autoimmune adrenalitis and infectious agents play a major role. The initial host defense against bacterial infections is executed primarily by the pattern recognition receptors, e.g. Toll-like receptors (TLRs), expressed in cells from the innate immune system. Upon activation, TLRs have been found to regulate various levels of innate and adaptive immunity as well as control tissue inflammation. TLRs are implicated in adrenal cell turnover and steroidogenesis during inflammation. Therefore, TLRs play a crucial role in the activation of adrenal inflammation mediating adrenal gland dysfunction during septicemia.

  2. Adrenal Insufficiency as a Cause of Acute Liver Failure: A Case Report

    Full Text Available Introduction. Many diseases and conditions can contribute to elevated liver enzymes. Common causes include viral and autoimmune hepatitis, fatty liver, and bile duct diseases, but, in uncommon cases like liver involvement in endocrine disorders, liver failure is also seen. Adrenal insufficiency is the rarest endocrine disorder complicating the liver. In the previously reported cases of adrenal insufficiency, mild liver enzymes elevation was seen but we report a case with severe elevated liver enzymes and liver failure due to adrenal insufficiency. Based on our knowledge, this is the first report in this field. Case Report. A 39-year-old woman was referred to emergency ward due to drowsiness and severe fatigue. Her laboratory tests revealed prothrombin time: 21 sec, alanine aminotransferase (ALT: 2339 IU/L, aspartate aminotransferase (AST: 2002 IU/L, and ALP: 90 IU/L. No common cause of liver involvement was discovered, and eventually, with diagnosis of adrenal insufficiency and corticosteroid therapy, liver enzymes and function became normal. Finally, the patient was discharged with good general condition. Conclusion. With this report, we emphasize adrenal insufficiency (primary or secondary as a reason of liver involvement in unexplainable cases and recommend that any increase in the liver enzymes, even liver failure, in these patients should be observed.

  3. Pituitary Adenoma as a Rare Form of Secondary Adrenal Insufficiency. A Case Report

    Full Text Available Pituitary adenomas are benign tumors arising from one of the five cell types in the anterior pituitary. Secondary adrenal insufficiency occurs when the adrenal glands do not produce hormones due to the lack of pituary adrenocorticotropic hormone or hypothalamic corticotropin-releasing factor. The case of a 37-year-old female patient who started developing muscle twitching in legs and arms, muscular weakness, fatigue, muscle aches, severe and throbbing hemicrania on the right side, among other symptoms, a year ago is presented. Several tests were performed (cortisol level, adrenocorticotropic hormone, calcium and phosphorus in blood and urine, magnetic resonance imaging of the skull, leading to the diagnosis of pituitary adenoma with isolated adrenocorticotropic hormone deficiency and secondary adrenal insufficiency. Treatment with steroids and calcium supplements ensured a satisfactory recovery.

    2013-01-01

    Full Text Available Purpose. Adrenocorticotropin- (ACTH- secreting pituitary carcinomas are rare and require multimodality treatment. The aim of this study was to report the response to various therapies and discuss the potential development of secondary adrenal insufficiency with cytotoxic chemotherapy. Methods. This report describes a man with a large silent corticotroph adenoma progressing to endogenous hypercortisolism and metastatic ACTH-secreting pituitary carcinoma over a period of 14 years. Results. Seven years after initial presentation, progressive tumor enlargement associated with the development of hypercortisolism mandated multiple pituitary tumor debulking procedures and radiotherapy. Testing of the Ki-67 proliferation index was markedly high and he developed a hepatic metastasis. Combination therapy with cisplatin and etoposide resulted in a substantial reduction in tumor size, near-complete regression of his liver metastasis, and dramatic decrease in ACTH secretion. This unexpectedly resulted in symptomatic secondary adrenal insufficiency. Conclusions. This is the first reported case of secondary adrenal insufficiency after use of cytotoxic chemotherapy for metastatic ACTH-secreting pituitary carcinoma. High proliferative indices may be predictive of dramatic responses to chemotherapy. Given the potential for such responses, the development of secondary adrenal insufficiency may occur and patients should be monitored accordingly.

    We have recently demonstrated that endotoxin causes oxidative stress and overproduction of nitric oxide in adrenal glands, thereby leading to adrenocortical insufficiency. The aim of this study is to investigate the effects of resveratrol, a natural plant polyphenol with anti-oxidant and anti-nitrative properties, on endotoxemia-associated adrenocortical insufficiency. Resveratrol was administered immediately before injection of lipopolysaccharide (LPS). Twenty four hours later, the adrenocorticotropic hormone (ACTH) stimulation tests was been performed to measure the plasma corticosterone level and the adrenal gland tissues were collected for histopathologic examination, and determination of malondialdehyde (MDA), total antioxidant capacity (T-AOC), superoxide dismutase (SOD) activity, catalase (CAT) activity, inducible nitric oxide synthase (iNOS) expression, nitric oxide (NO) and peroxynitrite production. Treatment with resveratrol significantly inhibited endotoxemia-induced iNOS expression, NO production, and peroxynitrite formation and also attenuated LPS-induced oxidative stress in the adrenal gland, as evidenced by the decrease of pro-oxidant biomarker (MDA), and the increases of anti-oxidant biomarkers (T-AOC, CAT and SOD activity). H&E staining demonstrated that administration of LPS resulted in increased into the adrenal gland. H&E-stained sections of adrenal glands demonstrated signs of leukocyte infiltration and hemorrhage during endotoxemia, which were significantly improved by resveratrol treatment. In addition, resveratrol reversed the LPS-induced downregulation of ACTH receptor and silent information regulator 1 (SIRT1) in adrenal gland, as well as adrenocortical hyporesponsiveness to ACTH. Resveratrol exerts protective effects against endotoxemia-associated adrenocortical insufficiency by suppressing oxidative/nitrative stress. These findings support the potential for resveratrol as a possible pharmacological agent to improve adrenocortical

    Glucocorticoid replacement is needed for patients after adrenal surgery for Cushing's syndrome; however, the adequate dosage is not easily determined. The patient was a 62-year-old woman who has had hypertension for 5 years and presented with heart failure due to hypertrophic cardiomyopathy. She consulted with us because of general fatigue, facial edema, and muscle weakness and was diagnosed with Cushing's syndrome. A laparoscopic left adrenalectomy was performed, standard dosage of postoperative replacement was administered, and she was discharged with 30 mg/day of hydrocortisone (cortisol). However, she suffered from loss of appetite and was transferred to an emergency unit with the symptoms of adrenal insufficiency on postoperative day 15. After initial hydrocortisone replacement with 200 mg/day, the dosage was gradually decreased during hospitalization; however, reduction of hydrocortisone dosage lower than 60 mg/day was difficult because of nausea and fatigue. Her circadian cortisol profile after hydrocortisone administration showed delayed and lowered peaks, which suggested that hydrocortisone absorption in the intestine was impaired. Therefore, complicated heart failure may have led to the adrenal insufficiency in the patient. In such cases, we should consider postoperative administration of more than the standard dosage of hydrocortisone to avoid adrenal insufficiency after surgery for Cushing's syndrome.

    2015-08-01

    The aim of this study was to examine the incidence of adrenal crises (AC) and the prescription of short-acting glucocorticoids (GC) in different geographic areas. To do this we conducted a descriptive study of AC hospitalisations and prescriptions for two GCs (hydrocortisone (HC) and cortisone acetate (CA)), and fludrocortisone acetate (FA), in different geographic areas of Australia between 1999/2000 and 2011/2012, using government databases.There were 2,584 hospital admissions for AC in Australia between 1999/00 and 2011/12 and the corresponding admission rates increased significantly from 7.4 to 11.1/10(6)/year (p<0.001). AC admission rates increased in 5 out of 6 geographic areas. Prescription rates for the combined GCs (HC/CA) increased at an annual rate of between 0.2-2.0% in all areas. All areas had significant (p<0.01) increases in HC prescription rates (4.5% to 13.7% annually) and CA prescription rates decreased in 5 out of the 6 regions (3.5% annual decrease to a 0.5% annual increase). When the geographic areas were combined, there was a significant correlation between the AC admission rates and HC/CA prescription rates (r=0.30, p<0.01). Admissions for AC and GC prescriptions increased significantly in Australia after 1999 and these varied significantly by geographic area. These results suggest that modern recommendations for lower dose, short-acting GC replacement may be of concern and further investigation is warranted. PMID:25951324

    A patient previously treated for bilateral breast cancer with mastectomy, radiation therapy and in remission on hormonal therapy for more than five years presented with abdominal symptoms from breast cancer relapse. She developed inappropriate polyuria and hypernatraemia, which responded to desmopressin. In combination with the absence of a high signal from the posterior lobe of the pituitary on MRI , these data indicated the presence of partial central diabetes insipidus. The anterior pituitary showed partial failure (low follicle-stimulating hormone, luteinising hormone and insulin-like growth factor-1 levels). Furthermore, primary adrenal insufficiency had developed, ascribed to bilateral tumour invasion of the adrenals. This rare combination of endocrinological failures in a patient with metastatic breast cancer is discussed.

    Primary adrenal insufficiency (PAI), or Addison's disease, is a rare, potentially deadly, but treatable disease. Most cases of PAI are caused by autoimmune destruction of the adrenal cortex. Consequently, patients with PAI are at higher risk of developing other autoimmune diseases. The diagnosis of PAI is often delayed by many months, and most patients present with symptoms of acute adrenal insufficiency. Because PAI is rare, even medical specialists in this therapeutic area rarely manage more than a few patients. Currently, the procedures for diagnosis, treatment and follow-up of this rare disease vary greatly within Europe. The common autoimmune form of PAI is characterized by the presence of 21-hydroxylase autoantibodies; other causes should be sought if no autoantibodies are detected. Acute adrenal crisis is a life-threatening condition that requires immediate treatment. Standard replacement therapy consists of multiple daily doses of hydrocortisone or cortisone acetate combined with fludrocortisone. Annual follow-up by an endocrinologist is recommended with the focus on optimization of replacement therapy and detection of new autoimmune diseases. Patient education to enable self-adjustment of dosages of replacement therapy and crisis prevention is particularly important in this disease. The authors of this document have collaborated within an EU project (Euadrenal) to study the pathogenesis, describe the natural course and improve the treatment for Addison's disease. Based on a synthesis of this research, the available literature, and the views and experiences of the consortium's investigators and key experts, we now attempt to provide a European Expert Consensus Statement for diagnosis, treatment and follow-up.

He also reported a hypersexual reaction to his own past cessation of MPA. Gonadotropin-releasing hormone agonists, which have a more benign side-effect profile than MPA, are suggested as an alternative to MPA.

    for diagnosing and treating adrenal insufficiency in patients with septic shock. SOURCES OF DATA: Articles published in Brazilian and foreign journals selected through these publications' websites and Medline, as well as references cited in key articles. SUMMARY OF THE FINDINGS: The literature reports a range betwen 17 and 54 % for the finding of adrenal insufficiency in patients with septic shock. There is no consensus for diagnosing adrenal insufficiency in patients suffering from critical diseases, particularly in patients with septic shock. The presence of volume-refractory and catecholamine-resistant septic shock suggests this condition, while basal cortisol under 25 µg/dl is a diagnostic criterion indicating adrenal insufficiency. The adrenal stimulation test is a useful resource for identifying patients with relative adrenal insufficiency. Our testing option for adrenal stimulation in children is the use of corticotropin in low doses (0.5 µg/1,73 m². An increase of less than 9 µg/dl in the value of postcorticotropin-stimulated cortisol suggests the presence of occult (relative adrenal insufficiency. In patients with septic shock presenting adrenal insufficiency, either suspected or confirmed, the administration of hydrocortisone in shock or stress doses can be vital for a favorable clinical outcome. CONCLUSIONS: The existing data, although controversial, already provides a basis to determine when to begin hormone replacement therapy, the serum level of cortisol accepted as adequate, and the choice of corticotropin doses for performing the adrenal stimulation test and diagnosing occult or relative adrenal insufficiency in patients with septic shock.

    Wilson's disease typically presents symptoms associated with liver damage or neuropsychiatric disturbances, while endocrinologic abnormalities are rare. We report an unprecedented case of hypopituitarism in a patient with Wilson's disease. A 40-year-old woman presented with depression, general weakness and anorexia. Laboratory tests and imaging studies were compatible with liver cirrhosis due to Wilson's disease. Basal hormone levels and pituitary function tests indicated secondary hypothyroidism and adrenal insufficiency due to hypopituitarism. Brain MRI showed T2 hyperintense signals in both basal ganglia and midbrain but the pituitary imaging was normal. She is currently receiving chelation therapy along with thyroid hormone and steroid replacement. There may be a relationship between Wilson's disease and hypopituitarism. Copper deposition or secondary neuronal damage in the pituitary may be a possible explanation for this theory.

    Full Text Available A 73-year-old woman admitted to our hospital because of headache, poor appetite, malaise, weight loss, and vomiting was found to have central adrenal insufficiency and thyrotoxicosis due to silent thyroiditis. Polyuria developed after replacement with glucocorticoid (masked diabetes insipidus, which was controlled with nasal administration of desmopressin. Magnetic resonance imaging of the brain showed a large cystic pituitary mass (18 × 18 × 12 mm extending suprasellarly to the optic chiasm. Transsphenoidal surgery revealed that the pituitary tumor was Rathke’s cleft cyst. Following surgery, replacement with neither glucocorticoid nor desmopressin was needed any more. Therefore, it is suggested that Rathke’s cleft cyst is responsible for the masked diabetes insipidus and the central insufficiency. Furthermore, it is speculated that thyrotoxicosis with painless thyroiditis might induce changes from subclinical adrenal insufficiency to transiently overt insufficiency.

    Full Text Available Abstract Background The aim was to survey current practice in glucocorticoid replacement therapy and self-perceived health outcomes in patients with adrenal insufficiency. Methods Participants were recruited via patient organizations to respond anonymously to a web-based survey developed by clinical experts. Unique entries were set up for each patient organization enabling geographical localization of the entries. Results 1245 participants responded (primary adrenal insufficiency: 84%; secondary adrenal insufficiency: 11%; unsure: 5%. Therapies included hydrocortisone (75%, prednisone/prednisolone (11%, cortisone acetate (6% and dexamethasone (4%. Dosing regimens were once daily (10%, twice daily (42%, thrice daily (32% or other (17%. Compromised subjective health necessitating changes to physical activity or social-, work- or family life was reported by 64% of the participants. 40% of the participants reported absence from work/school in the last 3 months. Irrespective of diagnosis, 76% were concerned about long-term side-effects of therapy, mainly osteoporosis (78%, obesity (64% and cardiovascular morbidity (46%. 38% of the participants had been hospitalized in the last year. Conclusions Glucocorticoid replacement therapy among the respondents consisted primarily of hydrocortisone administered twice or thrice daily. A majority reported impact of their disease or treatment on subjective health requiring alterations in e.g. physical activity or family life. Three quarters reported concerns about long-term side-effects of the treatment. These data demonstrate - from the patients' perspective - a need for improvement in the management of adrenal insufficiency.

    Steroidogenic factor 1 (SF-1) gene, identified by Keith Parker in 1992, encodes for an orphan nuclear receptor, NR5A1, whose expression is detected during fetal life in adrenal and gonadal steroidogenic tissues, but also in the developing hypothalamus and in pituitary gonadotropic cells. SF-1 knock-out mouse models exhibit complete adrenal and gonadal agenesis. Human mutations of this transcription factor, were initially associated with primary adrenal failure and male gonadal dysgenesis with various degrees of under androgenization. More recently, identification of novel SF-1 mutations responsible for isolated 46, XY gonadal dysgenesis or 46, XX primary ovarian insufficiency, underscores its central role in the control and maintenance of adrenal and reproductive functions. A better understanding in the regulatory mechanisms of SF-1 signaling pathway, will open new avenues for diagnostic and therapeutic managements of sex differentiation disorders and infertilities.

    Objective: This clinical practice guideline addresses the diagnosis and treatment of primary adrenal insufficiency. Participants: The Task Force included a chair, selected by The Clinical Guidelines Subcommittee of the Endocrine Society, eight additional clinicians experienced with the disease, a methodologist, and a medical writer. The co-sponsoring associations (European Society of Endocrinology and the American Association for Clinical Chemistry) had participating members. The Task Force received no corporate funding or remuneration in connection with this review. Evidence: This evidence-based guideline was developed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system to determine the strength of recommendations and the quality of evidence. Consensus Process: The evidence used to formulate recommendations was derived from two commissioned systematic reviews as well as other published systematic reviews and studies identified by the Task Force. The guideline was reviewed and approved sequentially by the Endocrine Society's Clinical Guidelines Subcommittee and Clinical Affairs Core Committee, members responding to a web posting, and the Endocrine Society Council. At each stage, the Task Force incorporated changes in response to written comments. Conclusions: We recommend diagnostic tests for the exclusion of primary adrenal insufficiency in all patients with indicative clinical symptoms or signs. In particular, we suggest a low diagnostic (and therapeutic) threshold in acutely ill patients, as well as in patients with predisposing factors. This is also recommended for pregnant women with unexplained persistent nausea, fatigue, and hypotension. We recommend a short corticotropin test (250 μg) as the “gold standard” diagnostic tool to establish the diagnosis. If a short corticotropin test is not possible in the first instance, we recommend an initial screening procedure comprising the measurement of morning plasma ACTH

    2016-01-01

    Purpose: The aim of this study was to characterize the brain ultrasonographic findings of late-onset circulatory dysfunction (LCD) due to adrenal insufficiency (AI) in preterm infants. Methods: Among the 257 preterm infants born at AI. Brain ultrasonographic findings were retrospectively analyzed before and after LCD in 14 preterm infants, after exclusion of the other 21 infants with AI due to the following causes: death (n=2), early AI (n=5), sepsis (n=1), and patent ductus arteriosus (n=13). Results: Fourteen of 257 infants (5.4%) were diagnosed with LCD due to AI. The age at LCD was a median of 18.5 days (range, 9 to 32 days). The last ultrasonographic findings before LCD occurred showed grade 1 periventricular echogenicity (PVE) in all 14 patients and germinal matrix hemorrhage (GMH) with focal cystic change in one patient. Ultrasonographic findings after LCD demonstrated no significant change in grade 1 PVE and no new lesions in eight (57%), grade 1 PVE with newly appearing GMH in three (21%), and increased PVE in three (21%) infants. Five infants (36%) showed new development (n=4) or increased size (n=1) of GMH. Two of three infants (14%) with increased PVE developed cystic periventricular leukomalacia (PVL) and rapid progression to macrocystic encephalomalacia. Conclusion: LCD due to AI may be associated with the late development of GMH, increased PVE after LCD, and cystic PVL with rapid progression to macrocystic encephalomalacia. PMID:27156563

    BACKGROUND Glucocorticoid replacement is commonly required to treat secondary adrenal insufficiency after surgical resection of unilateral cortisol-secreting adrenocortical adenomas. Here, we describe a patient with unilateral cortisol-secreting adenomas in which the preoperative use of mifepristone therapy was associated with recovery of the hypothalamic–pituitary–adrenal (HPA) axis, eliminating the need for postoperative glucocorticoid replacement. CASE PRESENTATION A 66-year-old Caucasian man with type 2 diabetes mellitus, hyperlipidemia, hypertension, and obesity was hospitalized for Fournier’s gangrene and methicillin-resistant Staphylococcus aureus sepsis. Abdominal computed tomography scan revealed three left adrenal adenomas measuring 1.4, 2.1, and 1.2 cm and an atrophic right adrenal gland. Twenty-four-hour urinary free cortisol level was elevated (237 µg/24 hours, reference range 0–50 µg/24 hours). Hormonal evaluation after resolution of the infection showed an abnormal 8 mg overnight dexamethasone suppression test (cortisol postdexamethasone 14.5 µg/dL), suppressed adrenocorticotropic hormone (ACTH; <5 pg/mL, reference range 7.2–63.3 pg/mL), and low-normal dehydroepiandrosterone sulfate (50.5 µg/dL, male reference range 30.9–295.6 µg/dL). Because of his poor medical condition and uncontrolled diabetes, his Cushing’s syndrome was treated with medical therapy before surgery. Mifepristone therapy was started and, within five months, his diabetes was controlled and insulin discontinued. The previously suppressed ACTH increased to above normal range accompanied by an increase in dehydroepiandrosterone sulfate levels, indicating recovery of the HPA axis and atrophic contralateral adrenal gland. The patient received one precautionary intraoperative dose of hydrocortisone and none thereafter. Two days postoperatively, ACTH (843 pg/mL) and cortisol levels (44.8 µg/dL) were significantly elevated, reflecting an appropriate HPA axis response to

    Activation of sympato-adrenal system plays an important role in the development of chronic cardiac failure (CCF). However, its relation to morpho-functional state of myocardium in CCF patients is virtually unknown. HPLC with electrochemical detection was used to determine plasma noradrenalin, adrenalin, and their precursors, 3,4-dioxyphenylalanine (DOPA) and dopamine, in patients with different morpho-functional changes in myocardium. The study demonstrated enhanced activity of sympato-adrenal system in patients with CCF. It showed for the first time that activity of sympato-adrenal system in CCF patients depends on the morpho-functional status of myocardium.

    2016-01-01

    For a long time it has been assumed that patients with chronic adrenal insufficiency under established replacement therapy have a normal life expectancy and a normal everyday life. Recent studies now indicate both an impairment of quality of life (QoL) with a negative impact on daily life and increased mortality in a significant number of patients. The clinical presentation of patients varies considerably. While some neither suffer from reduced QoL nor from adrenal crisis, others are significantly more affected by the disease. Long-term management of patients is thus more challenging and goes far beyond identification of the correct maintenance dose of corticosteroids. The mortality from adrenal crisis is still high and prevention should be a top priority for endocrinologists. Concepts of replacement therapy as well as patient education and emergency equipment are currently being reassessed. Developments to improve patient care and treatment comprise novel glucocorticoid preparations that are closer to the physiological circadian cortisol profile, a uniform European emergency card and more standardized crisis prevention measures.

    Glucocorticoids are commonly used in anti-inflammatory and immunomodulatory therapies, but glucocorticoid withdrawal can result in life-threatening risk of adrenal insufficiency. Chinese patented pharmaceutical product Jinkui Shenqi pill (JKSQ) has potent efficacy on clinical adrenal insufficiency resulting from glucocorticoid withdrawal. However, the underlying molecular mechanism remains unclear. We used an animal model to study JKSQ-induced metabolic changes under adrenal insufficiency and healthy conditions. Sprague-Dawley rats were treated with hydrocortisone for 7 days with or without 15 days of JKSQ pretreatment. Sera were collected after 72 h hydrocortisone withdrawal and used for global and free fatty acids (FFAs)-targeted metabolomics analyses using gas chromatography/time-of-flight mass spectrometry and ultraperformance liquid chromatography/quadruple time-of-flight mass spectrometry. Rats without hydrocortisone treatment were used as controls. JKSQ pretreatment normalized the significant changes of 13 serum metabolites in hydrocortisone-withdrawal rats, involving carbohydrates, lipids, and amino acids. The most prominent effect of JKSQ was on the changes of FFAs and some [product FFA]/[precursor FFA] ratios, which represent estimated desaturase and elongase activities. The opposite metabolic responses of JKSQ in adrenal insufficiency rats and normal rats highlighted the "Bian Zheng Lun Zhi" (treatment based on ZHENG differentiation) guideline of TCM and suggested that altered fatty acid metabolism was associated with adrenal insufficiency after glucocorticoid withdrawal and the protective effects of JKSQ.

    Glucocorticoid treatment in adrenal insufficiency remains a challenge since many patients complain of fatigue, reduced health-related quality of life and working ability. Moreover, there is a fear of increased mortality and morbidity related to adrenal crises and chronic overexposure to glucocorticoids. In order to counter these negative effects on daily life and future health, recent recommendations speak for lower replacement doses and administration forms that attempt to mimic the circadian variation in cortisol. At the same time, low replacement doses should not put the patient at an increased risk of an adrenal crisis. This chapter provides an overview of current state-of-the-art approaches to treatment and follow-up of adrenal insufficiency aimed at avoiding over- and undertreatment.

  11. Adrenal Insufficiency in Australia: Is it Possible that the Use of Lower Dose, Short-Acting Glucocorticoids has Increased the Risk of Adrenal Crises?

    Morbidity from adrenal insufficiency (AI) in Australia is poorly described. The objective of this study was to evaluate AI morbidity patterns in adults between 1999/2000 and 2011/2012 using national databases. A descriptive study of hospitalisations for AI and adrenal crises (AC) in adults and trends in prescriptions for 2 short-acting glucocorticoids (GC) was designed. The setting was the Australian healthcare system. Main outcome measures are the trends in hospitalisation and prescription rates. There were 7,378 hospital admissions for treatment of AI in adults between 1999/00 and 2011/12. Of these, 29.5% were for an AC. Admission rates for AC increased from 9.5 to 12.4 admissions/10(6)/year (p hydrocortisone (HCT) and cortisone acetate (CA)] prescription rates increased significantly (p < 0.001) from 3,176.1/10(6) to 3,463.8/10(6). Prescription rates for CA decreased by 22.4% (p < 0.001) but HCT prescription rates increased to 77.1% (p < 0.001). The increase in AC admission rates was positively correlated with the rise in both the total GC prescription rate (r = 0.63, p < 0.05) and the HCT prescription rate (r = 0.74, p< 0.01). Over the 13-year study period, there was a 30.8% increase in hospitalisation rates for ACs and a concomitant 77.1% increase in prescribing of HCT. The association between AC events and HCT use and/or reduced effective GC dose is plausibly causal, but confirmatory studies are required before suggesting any change to GC replacement in AI.

    Chronic adrenal insufficiency (CAI) is characterized by a lack of glucocorticoid and mineralocorticoid production due to destroyed adrenal cortex cells. However, elevated cortisol secretion is thought to be a central part in a well-orchestrated immune response to stress. This raises the question to what extent lack of cortisol in CAI affects stress-related changes in immune processes. To address this question, 28 CAI patients (20 females) and 18 healthy individuals (11 females) (age: 44.3 ± 8.4 years) were exposed to a psychosocial stress test (Trier Social Stress Test: TSST). Half the patients received a 0.03 mg/kg body weight injection of hydrocortisone (HC) post-TSST to mimic a healthy cortisol stress response. Catecholamines and immune cell composition were assessed in peripheral blood and free cortisol measured in saliva collected before and repeatedly after TSST. CAI patients showed norepinephrine (NE) stress responses similar to healthy participants, however, epinephrine (E) as well as cortisol levels were significantly lower. HC treatment post-TSST resulted in cortisol increases comparable to those observed in healthy participants (interaction effects--NE: F=1.05, p=.41; E: F=2.56, p=.045; cortisol: F=13.28, pcortisol's central involvement in post-stress lymphocyte migration from blood into immune-relevant body compartments. As such, future studies should investigate whether psychosocial stress exposure may put CAI patients at an increased health risk due to attenuated immune responses to pathogens.

    Full Text Available Objective. Noninsulinoma pancreatogenous hypoglycemia syndrome (NIPHS is a disorder of endogenous hyperinsulinemia that is clinically distinguishable from insulinoma, with a greater preponderance after Roux-en-Y gastric bypass (RYBG. Hyperinsulinemic hypoglycemia can predispose to attenuation of counterregulatory hormone responses to hypoglycemia, and consequent suppression of the hypothalamic–pituitary–adrenal (HPA axis. This case series describes 3 individuals who were diagnosed with adrenal insufficiency (AI after undergoing RYGB, complicated by NIPHS. Methods. A retrospective chart review was performed for each individual. Chart review applied particular attention to the onset of hyperinsulinemic hypoglycemia following bariatric surgery and the dynamic testing leading to the diagnoses of NIPHS and AI. Results. In each case, reactive hypoglycemia ensued within months to years after RYGB. Cosyntropin stimulation testing confirmed the diagnosis of AI. Hydrocortisone therapy reduced the frequency and severity of hypoglycemia and was continued until successful medical and/or surgical management of hyperinsulinism occurred. Follow-up testing of the HPA axis demonstrated resolution of AI. In all cases, hydrocortisone therapy was finally discontinued without incident. Conclusion. We speculate that transient AI is a potential complication in patients who experience recurrent hyperinsulinemic hypoglycemia after RYGB. The putative mechanism for this observation may be attenuation of the HPA axis after prolonged exposure to severe, recurrent hypoglycemia. We conclude that biochemical screening for AI should be considered in individuals who develop post-RYGB hyperinsulinemic hypoglycemia. If AI is diagnosed, supportive treatment should be maintained until hyperinsulinemic hypoglycemia has been managed effectively.

    The treatment of chronic inflammatory skin disease is associated with the use of topical corticosteroids. Their efficacy, tolerability and adverse effects depend on several factors, specifically potency, type of preparation, extemporaneous dilutions, quantity used, magnitude of the treated body surface, frequency of application, location, patient age, method of application and condition of the skin barrier. We report on two men suffering from chronic inflammatory skin disease, who presented with fatigue and cushingoid appearance after prolonged self-application of potent corticosteroids. Impairment of the skin barrier due to their underlying skin disease, frequent self-application of topical steroids and repeated application of the entire body led to extensive absorption of these substances, eventually culminating in the suppression of the pituitary-hypothalamic-adrenal axis. In conclusion, topical corticosteroids are effective and well-established therapeutic modalities. However, inappropriate use of topical corticosteroids can cause side effects. PMID:24751677

    We describe a case of Takotsubo cardiomyopathy in a case of pituitary macroadenoma in acute adrenal crisis. A 48-year-old man presented with acute onset altered sensorium, vomiting, and gasping. On admission, he was unresponsive and hemodynamically unstable. He was intubated and ventilated and resuscitated with fluids and inotropes. The biochemical evaluation revealed hyponatremia, hyperkalemia, and hypocortisolism. Hyponatremia was corrected with 3% hypertonic saline. Contrast enhanced computed tomography (CT) scan of the brain revealed a sellar-suprasellar mass with hypothalamic extension with no evidence of pituitary apoplexy. A diagnosis of invasive pituitary adenoma with the Addisonian crisis was made and steroid replacement was initiated. Despite volume resuscitation, he had persistent refractory hypotension, recurrent ventricular tachycardia, and metabolic acidosis. Electrocardiogram (ECG) showed ST elevation and T-wave inversion in lateral leads; cardiac-enzymes were increased suggestive of acute coronary syndrome. Transthoracic echocardiography showed severe regional wall motion abnormalities (RWMAs) involving left anterior descending territory and low ejection fraction (EF). Coronary angiogram revealed normal coronaries, apical ballooning, and severe left ventricular dysfunction, consistent with a diagnosis of Takotsubo's cardiomyopathy. Patient was managed with angiotensin-converting enzyme inhibitors and B-blockers. He improved over few days and recovered completely. At discharge, ECG changes and RWMA resolved and EF normalized to 56%. In patients with Addisonian Crisis with persistent hypotension refractory to optimal resuscitation, possibility of Takotsubo's cardiomyopathy should be considered. Early recognition of association of Takotsubos cardiomyopathy in neurological conditions, prompt resuscitation, and supportive care are essential to ensure favorable outcomes in this potentially lethal condition.

    Reznik, Yves

    2016-06-01

    Intensive researches on modified-release hydrocortisone compounds developed in the last decade have paved the way for obtaining near-physiological glucocorticoid replacement in the adrenal insufficient patient. The dual-release Duocort (Plenadren) allows a unique morning intake and closely mimics the circadian rhythm of cortisol secretion, except for the progressive nocturnal increase and the morning cortisol peak observed in healthy subjects. Duocort treatment during a 6-month period was associated with favorable changes in weight, blood pressure and glycemic control in patients with diabetes mellitus. Chronocort, a multiparticulate formulation with sustained-release properties replaces endogenous cortisol in a near-physiologic manner and fully restores the end of night cortisol peak. A twice-daily Chronocort regimen was effective in controlling androgen excess in adults with CAH. Recently, the new multiparticulate formulation Infacort was designed for the treatment of adrenal insufficiency during infancy. Long term effectiveness and safety studies are needed until these promising hydrocortisone formulations become routine therapeutic tools in adrenal insufficiency. PMID:27260966

    Adrenal insufficiency(AI) is a disorder that can result from primary adrenal failure(primary type) or secondary adrenal disease due to impairment of the hypothalamic-pituitary axis (central type).It is characterized by glucocorticoid deficiency,with or without inappropriate mineralocorticoid or androgen production.The diagnosis and management of children with AI remain challenging as clinical characteristics of AI in children maybe non-specific and acute adrenal crisis is life-threatening,needing life-long glucocorticoid replacement treatment and education of the patient and the family.New formulations of hydrocortisone which should be able to simulate the circadian rhythm of steroid secretion are supposed to improve outcome in patients with adrenal insufficiency in the near future.%儿童肾上腺皮质功能减退(AI)是指源于下丘脑-垂体-肾上腺轴功能损害的一组综合征,可为原发肾上腺衰竭(原发性),或继发于下丘脑-垂体轴病变的肾上腺疾病(中枢性).临床表现为糖皮质激素(GC)分泌不足或作用缺陷,伴或不伴盐皮质激素分泌异常、伴或不伴雄激素分泌异常.因临床特点非特异而常不被知悉,急性肾上腺危象则可威胁生命,需要立即得到诊治.长期GC替代、家庭教育是儿童AI管理的2个重要组成部分,同时必须严密监测以防治疗不足或过度.氢化可的松新型制剂——双释放剂型已经研制成功,其对于改善患儿的治疗依从性、维持皮质醇的分泌节律、改善患儿的预后可能具有广阔的前景.

    Full Text Available The authors report two cases of adrenal insufficiency secondary to infiltration of the adrenal glands by Paracoccidioides brasiliensis. The first patient had been treated for a chronic multifocal form of paracoccidiodomycosis 11 years ago. The diagnosis of the mycosis was done simultaneous with that of the adrenal insufficiency in the second patient. In both patients the diagnosis was done by direct visualization of fungus in adrenal biopsies. They were treated with hormonal supplements and itraconazol by 12 and six months, without relapses during the follow-up period.Os autores apresentam dois casos de insuficiência supra-renal secundária à infiltração das adrenais pelo Paracoccidioides brasiliensis. O primeiro paciente tinha sido tratado de paracoccidioidomicose crônica multifocal 11 anos atrás. No segundo paciente, o diagnóstico da micose foi feito de forma simultânea com o da insuficiência adrenal. Em ambos os pacientes, o diagnóstico foi feito pela visualização direta do fungo nas biopsias adrenais. Eles foram tratados com suplementos hormonais com itraconazol por seis a 12 meses, sem recaídas durante o período de acompanhamento.

    Central adrenal insufficiency (CAI) in acromegaly may be related to pituitary adenoma or induced by various medical treatments, transsphenoidal neurosurgery (TNS) or radiotherapy (RT), alone or combined. We assessed the role of all available treatments for acromegaly in inducing CAI. We retrospectively studied 97 patients. CAI was diagnosed if morning serum cortisol was acromegaly, invasion of cavernous sinus, disease control, and type of medical treatment were much the same for patients with and without CAI, which was identified in 18% of patients (10/57) after one TNS, and in 53% (9/17) after RT (p=0.01); repeat surgery increased the risk of CAI (p=0.02). The risk of CAI onset during the follow-up was lower among patients treated with TNS or medical therapy than after RT (p=0.035). Medical treatment did not raise the risk of CAI, whereas a 5- and 4-fold higher risk of CAI was associated with repeat TNS and RT, respectively. Basal or stimulated cortisol levels were similar among acromegalic patients without CAI and matched controls with nonsecreting pituitary lesions. A significant proportion of patients with acromegaly developed CAI over time. While primary or secondary medical treatment did not contribute to the risk of CAI, repeat TNS and RT correlated with pituitary-adrenal axis impairment. PMID:27246620

    Background In March 2015, the International Network of Clinicians for Endocrinopathies in Thalassemia and Adolescent Medicine (ICET-A) implemented a two-step survey on central adrenal insufficiency (CAI) assessment in TM patients and after analysis of the collected data, recommendations for the assessment of hypothalamic-pituitary- adrenal (HPA) axis in clinical practice were defined. Methods To ascertain the current practice for assessment of CAI in thalassemia, the Coordinator of ICET-A sent two questionnaires by email: i) The first to evaluate the current interpretation of basal serum cortisol level (first step) and ii) The second to assess the current usage of ACTH test and the variability in practice” (second step). Based on the surveys the core ICET-A group prepared the recommendations for the assessment of suspected CAI in thalassemia (third step). Results A total of 19 thalassemologists/endocrinologists have participated in the first survey and 35 specialists participated in the second step questionnaire. The study demonstrated a considerable variability in almost all aspects of relevant current criteria used for the diagnosis of CAI. An ROC analysis using peak value > 20 μg/dl (> 550 nmol/L), after ACTH stimulation test, was performed with the aim of identifying the optimal basal serum cortisol cut-off. The optimal threshold that maximizes sensitivity plus specificity for morning basal cortisol against peak post-ACTH value >20 μg/dl (>550 nmol/L) was 10 μg/dl (275 nmol/L). Furthermore, the values associated with the highest negative predictive value (NPV) and highest, positive predictive value (PPV) were 4.20 (115 nmol/L) and 18.45 μg/dl (510 nmol/L), respectively. Surprisingly, 20 specialists in thalassemia working in blood bank, thalassemia centres (day hospital), internal medicine, hematology and onco-hematology had poor knowledge and experience in testing for CAI and stopped filling the questionnaire after the second question. In contrast, 9

    In patients with adrenal insufficiency (AI) a higher hydrocortisone intake has been associated with more impairment in quality of life (QoL). Irrespective of age, sex and severity of AI the dosage of hydrocortisone is titrated around 20mg/D in all patients with AI based on physical and mental signs and symptoms. However, until now it is unknown whether these QoL impairments are related to increased systemic cortisol exposure. Measurement of hair cortisol levels (CORThair) can be used to assess chronic systemic cortisol exposure. This study aimed to explore whether QoL in patients with AI is associated with CORThair and daily hydrocortisone intake. We performed a cross-sectional study in 120 patients with AI on stable hydrocortisone replacement, in whom hair samples and QoL data were collected. CORThair were measured with ELISA, and QoL was assessed with validated questionnaires (SF-36, EQ-5D, HADS, MFI-20). Patients reported impairments in 14 of 15 QoL subscales (pAI report several impairments in QoL which are associated with hydrocortisone intake, and to a lesser extent reflected by chronic systemic cortisol exposure as measured by hair cortisol. This suggests that QoL impairments in patients with AI are not per se the effect of prolonged exposure to elevated systemic cortisol levels. PMID:27388687

    Our goals were to (1) develop an improved micro-method usable for neonates for steroid profile measurements and a method to measure androsterone, a key steroid in the recently described androgen backdoor pathway together, with dehydroepiandrosterone and (2) to assess if dehydroepiandrosterone diurnal concentration fluctuations exist potentially necessitating strict adherence to time of blood sample draw and requirement of separate time-dependent reference intervals. Liquid chromatography-tandem mass spectrometry was performed with an atmospheric pressure photoionization source [1]. For each sample 50μL (100μL for the backdoor pathway) of serum was deproteinized by adding 75μL (150μL for the backdoor pathway) of acetonitrile containing the internal standards. After centrifugation, 75μL (150μL for the backdoor pathway) of supernatant was diluted with 250μL of water and injected onto a Poroshell 120 EC-C8 column (SB-C8 column for the backdoor pathway). Within-run coefficients of variation ranged from 2.4 to 10.4% and between-day coefficients of variation from 2.9 to 11.2%. Comparison studies yielded correlation coefficient between 0.97 and 1.00 with recoveries of 90% or greater. Our methods analyze a 9 steroid profile and an additional 2 steroid profile (backdoor pathway) with minimal sample volume (usable in neonates optimizing early diagnosis of endocrinopathies and genetic diseases). Low limits of quantitation make these methods ideal for steroid measurement in women and prepubertal children. As diurnal variations of dehydroepiandrosterone and other steroids [2] concentrations are clinically significant we recommend that separate reference intervals be developed for 8 am, 8 pm, and midnight sample draws. The use of this approach in improving the diagnosis of patients with adrenal insufficiency and congenital adrenal hyperplasia is discussed. PMID:26721696

    Full Text Available Nonclassic congenital adrenal hyperplasia (NCAH due to P450c21 (21-hydroxylase deficiency is a common autosomal recessive disorder. This disorder is due to mutations in the CYP21A2 gene which is located at chromosome 6p21. The clinical features predominantly reflect androgen excess rather than adrenal insufficiency leading to an ascertainment bias favoring diagnosis in females. Treatment goals include normal linear growth velocity and “on-time” puberty in affected children. For adolescent and adult women, treatment goals include regularization of menses, prevention of progression of hirsutism, and fertility. This paper will review key aspects regarding pathophysiology, diagnosis, and treatment of NCAH.

Whereas radiological methods reflect morphological changes, scintigraphy of adrenal cortex and medulla depends on function. - Radiolabeled 6β-methyl-19-norcholesterol is used for adrenocortical scintigraphy in primary aldosteronism, Cushing's syndrome and hyperandrogenism. By dexamethasone suppression a correct classification of adrenocortical lesions by scintigraphy can be observed in about 89% with a specificity of 86%. 123-I- and 131-I-metaiodobenzylguanidine is used for specific scintigraphy of the adrenal medulla. This method is a safe and reliable method for localization of adrenal and extraadrenal pheochromocytomas. (orig.)

    Objective To examine the adrenal function of critically ill patients received mechanical ventilation, and explore the relationship between the occurrence of relative adrenal insufficiency (RAI) and weaning outcome. Methods Critically ill patients who were mechanically ventilated over 48 hours were enrolled in this study. Every patient was given one shot of corticotrophin 230μg intravenously on the first day of admission and the first day of spontaneous-breathing-trial (SBT). Plasma contisol level was detected by radio-immunoassay before (TO) and 30 minutes ( T30) after the shot. Meanwhile the following parameters were recorded including APACHE II , age, and cause of disease, etc. RAI was defined as the difference between TO and T30 ≤9μg/dL. Receiver operating characteristic ( ROC) curve was used to evaluate the accuracy of the indicators towards the weaning outcome. Results A total of 43 patients with mechanical ventilation were recruited. The successful weaning group consisted 29 patients and the failure weaning group consisted 16 patients. The incidence of RAI in the successful weaning group (37. 9% ,11/ 29) was significantly lower than that in the failure weaning group ( 75.0% , 12/16) (P = 0. 017). On the first day of admission,there was no significant difference of Acortisol between the successful weaning group and the failure weaning group [ (10. 3 ±5. 7)μg/dL vs. (7. 5 ±4. 5)μg/dL, P = 0. 100). On the firstSBT day, Acortisol of the successful weaning group was significantly higher than that in the failure weaning group [ (10. 9 ± 5. 1) μg/dL vs. (4. 9 ± 2.9)μg/dL, P = 0. 043 ]. Logistic regression analysis showed that △cortisol was an independent risk factor of weaning. ROC curve analysis showed that on the first SBT day, the area under the curve of Acortisol was 0. 872; The sensitivity and the specificity of accurate judgment were 0. 813 and 0. 828 if △cortisol ≤6. 95μg/dL. Conclusions The occurrence of RAI is common in critically ill

    Full Text Available Incidentally discovered adrenal masses, or adrenal incidentalomas, have become a common clinical problem owing to wide application of radiologic imaging techniques. This definition encompasses a heterogeneous spectrum of pathologic entities, including primary adrenocortical and medullary tumors, benign or malignant lesions, hormonally active or inactive lesions, metastases, and infections. Once an adrenal mass is detected, the clinician needs to address two crucial questions: is the mass malignant, and is it hormonally active? This article provides an overview of the diagnostic clinical approach and management of the adrenal incidentaloma. Mass size is the most reliable variable to distinguish benign and malignant adrenal masses. Adrenalectomy should be recommended for masses greater than 4.0 cm because of the increased risk of malignancy. Adrenal scintigraphy has proved useful in discriminating between benign and malignant lesions. Finally, fine-needle aspiration biopsy is an important tool in the evaluation of oncological patients and it may be useful in establishing the presence of metastatic disease. The majority of adrenal incidentalomas are non-hypersecretory cortical adenomas but an endocrine evaluation can lead to the identification of a significant number of cases with subclinical Cushing's syndrome (5-15%, pheochromocytoma (1.5-13% and aldosteronoma (0-7%. The first step of hormonal screening should include an overnight low dose dexamethasone suppression test, the measure of urinary catecholamines or metanephrines, serum potassium and, in hypertensive patients, upright plasma aldosterone/plasma renin activity ratio. Dehydroepiandrosterone sulfate measurement may show evidence of adrenal androgen excess.

    It is known that adrenal insufficiency is one of the complications in primary adrenal lymphoma, especially those with bilateral adrenal involvement. A 73-year-old man was referred for general fatigue and high fever to the nearest hospital. The patient was transferred to our hospital for evaluation of bilateral adrenal tumors and hyponatremia. He was diagnosed as having non-Hodgkin's lymphoma (NHL) with primaries arising in both adrenal glands. Primary adrenal lymphoma (PAL) is a rare extra-nodal NHL. Although an appropriate treatment of this disease has not been established, our case has demonstrated that the combination of rituximab and THP-COP chemotherapy could be administered, and that it improved clinical manifestations. This case raises the suggestion that malignant lymphoma should be suspected in patients with bilateral adrenal tumors that present with progressive adrenal insufficiency.

  8. Adrenal scintigraphy

    International Nuclear Information System (INIS)

    The visualization of functioning adrenocortical tissue by scintigraphy became possible with the introduction of radioiodinated cholesterol derivatives. According to the literature, there is evidence that one of these iodinated cholesterols, 6-β-iodomethyl-nor-cholesterol, concentrates in the adrenal cortex to a much greater extent than 131I-19-odocholesterol. Results comparing both radiopharmaceuticals are described. The authors investigated the possibility of increasing the uptake of iodinated cholesterol using simultaneous ACTH and the 'cholesterol side-chain cleavage enzymeblocker': aminoglutethimide. The results of adrenal scintigraphy performed in 37 patients are described. Finally, the literature on adrenal scintigraphy is reviewed, and results reported in various studies are compared. (Auth.)

    The large hyperaemic foetal adrenal gland is vulnerable to vascular damage. This may occur in the neonatal period as a consequence of difficult labour, or its aetiology may not be apparent. The spectrum of presentation is considerable, ranging from asymptomatic to severe life-threatening intra-abdominal haemorrhage. The presentation of adrenal insufficiency may be delayed but the regenerative capacity of the adrenal is great, and most adrenal haemorrhage is not associated with significantly impaired function. Some reports showed that cholestatic hepatopathy with congenital hypopituitarism reversed by hydrocortisone treatment is considered in the context of the endocrine syndrome, probably as a consequence of the adrenal failure. We describe a case of bilateral adrenal haemorrhage with hepatitis syndrome and persistent hypoglycaemia in a newborn male with striking features of neonatal cholestasis and adrenal crisis.

    Full Text Available INTRODUCTION: Congenital adrenal hyperplasia (CAH is an autosomal recessive disease whose main cause is the deficiency of 21-hydroxylase, an enzyme involved in the synthesis of cortisol and aldosterone. There are two forms of CAH, a classical and nonclassical form, being the first objective of analysis in the clinical case. Its clinical manifestations vary in severity, depending on the level of hormone deficiency. Within the classic is described the salt-wasting form, whose consequences are androgen excess and insufficiency of cortisol and mineralocorticoids.

    Bilateral adrenal hemorrhage (BAH) is a rare complication typically seen in critically ill patients, which can lead to acute adrenal insufficiency and death unless it is recognized promptly and treated appropriately. We describe the case of a 64-year-old man with polycythemia vera found to be unresponsive with fever, hypotension, tachycardia, and hypoglycemia. Electrocardiogram showed ST-elevation with elevated troponin, hemoglobin, prothrombin time, and partial thromboplastin time. He required aggressive ventilator and vasopressor support. Despite primary coronary intervention, he remained hypotensive. Random cortisol level was low. He received stress dose hydrocortisone with immediate hemodynamic stability. BAH was highly suspected and was confirmed by non-contrast abdominal computed tomography. Prompt recognition and timely initiated treatment remain crucial to impact the mortality associated with acute adrenal insufficiency. PMID:27609733

    Adrenal injuries, although an uncommon consequence of abdominal trauma, are important to recognize. If bilateral, adrenal trauma could result in life-threatening adrenal insufficiency. Furthermore, in the setting of trauma, adrenal injury can point to other concomitant injuries and has been associated with overall increased morbidity and mortality. In the past, before the advent of computed tomography (CT), detection was difficult, and the diagnosis was often made only at surgery or postmortem. Today, the diagnosis of adrenal injuries can be quickly and accurately made with CT. This retrospective review was carried out to identify, describe, and analyze different CT appearances of adrenal injuries and correlated with associated injuries and observed clinical context and outcomes. A patient cohort of CT-detected adrenal injuries was identified through a radiology software research tool by searching for keywords in radiology reports. The identified CT scans were reviewed and correlated with the patients' available clinical chart data and follow-up. Between April 1995 and October 2004, 73 cases of CT-detected adrenal injuries were identified, including 48 men and 25 women, with an age range 6 to 90 years and a mean age of 42.7 years. Of the cases, 77% were right-sided, 15% were left-sided, and 8% were bilateral. The causes of injuries were motor vehicle collisions (75%), falls (14%), sports related (4%), and miscellaneous causes (7%). Associated trauma included injuries of the liver (43%), spleen (23%), lung (19%), and kidney (18%), as well as pneumothoraces/hemothoraces (22%). Skeletal injuries included fractures of the ribs, clavicles, and/or scapulae (39%), pelvis and hips (30%), and the spine (23%). Isolated adrenal trauma was seen in only 4% of the cases. The CT findings of adrenal trauma were focal hematoma (30%), indistinct (27%) or enlarged (18%) adrenal gland, gross (15%) or focal (7%) adrenal hemorrhage, and adrenal mass (11%).

    Full Text Available Nonclassic congenital adrenal hyperplasia (NCAH due to P450c21 (21-hydroxylase deficiency is a common autosomal recessive disorder. This disorder is due to mutations in the CYP21A2 gene which is located at chromosome 6p21. The clinical features predominantly reflect androgen excess rather than adrenal insufficiency leading to an ascertainment bias favoring diagnosis in females. Treatment goals include normal linear growth velocity and "on-time" puberty in affected children. For adolescent and adult women, treatment goals include regularization of menses, prevention of progression of hirsutism, and fertility. This paper will review key aspects regarding pathophysiology, diagnosis, and treatment of NCAH.

    Human adrenal development is a complex and relatively poorly understood process. However, significant insight into some of the mechanisms regulating adrenal development and function is being obtained through the analysis of individuals and families with adrenal hypoplasia. Adrenal hypoplasia can occur: (1) secondary to defects in pituitary adrenocorticotropin (ACTH) synthesis, processing and release (secondary adrenal hypoplasia; e.g. HESX1, LHX4, SOX3, TPIT, pituitary POMC, PC1); (2) as part of several ACTH resistance syndromes (e.g. MC2R/ACTHR, MRAP, Alacrima, Achalasia, Addison disease), or as (3) a primary defect in the development of the adrenal gland itself (primary adrenal hypoplasia; e.g. DAX1/NR0B1 - dosage-sensitive sex reversal, adrenal hypoplasia congenita critical region on the X chromosome 1). Indeed, the X-linked form of primary adrenal hypoplasia due to deletions or mutations in the orphan nuclear receptor DAX1 occurs in around half of male infants presenting with a salt-losing adrenal crisis, where no obvious steroidogenic defect (e.g. 21-hydroxylase deficiency), metabolic abnormality (e.g. neonatal adrenoleukodystrophy) or physical cause (e.g. adrenal haemorrhage) is found. Establishing the underlying basis of adrenal failure can have important implications for investigating associated features, the likely long-term approach to treatment, and for counselling families about the risk of other children being affected.

    Full Text Available Lipoid congenital adrenal hyperplasia (lipoid CAH, a rare disorder of steroid biosynthesis, is the most severe form of CAH. In this disorder the synthesis of glucocorticoids, mineralocorticoids and sex steroids is impaired which result in adrenal failure, severe salt wasting crisis and hyperpigmentation in phenotypical female infants irrespective of genetic sex. In this report, we presented a 28-day-old phenotypic female infant, which referred with lethargy, failure to thrive and electrolyte abnormalities. Considering the clinical and biochemical findings, lipoid CAH was diagnosed and replacement therapy with standard doses of glucocorticoid and mineralocorticoid and sodium chloride was initiated. During follow-up, she had good clinical condition, but at 6 years of age, she refers with hypertension and adrenal insufficiency because of arbitrary drug discontinuation by mother. In ultrasonography an abdominal mass (the testicles was reported. Chromosome study showed 46XY pattern. Orchiectomy was performed. We recommended that in cases with clinical presentation of adrenal insufficiency if there is not the facility to determine the karyotype, repeated ultrasonography perform during follow-up. In addition, investigating the genetic bases of the disorder would help us to determine the pathogenesis of lipoid CAH in our community. It would be helpful in prenatal diagnosis and treatment of the disorder to prevent its related comorbidities.

    Adrenal schwannoma is an extremely uncommon cause of incidentaloma. It originates from neural sheath Schwann cells of the adrenal gland. We report the case of a left adrenal schwannoma incidentally discovered in a 32-year-old woman during examination of bloated feeling and stomach ache. The patient was incidentally found to have a left adrenal mass of 9 cm on abdominal ultrasonography. Computed tomography (CT) of the abdomen and [(18)F] fluorodeoxyglucose positron emission tomography (PET) were also performed. Metabolic evaluation was unremarkable. Due to the large size of the tumor, left adrenalectomy was performed. The postoperative course was uneventful. Histological examination established the diagnosis of schwannoma. This diagnosis was supported by immunohistochemistry of S-100 and vimentin positivity. In conclusion, adrenal schwannoma is an extremely rare entity and can grow considerably in size. The present case report emphasizes that clinicians should be aware of the possibility of retroperitoneal schwannoma. Total excision of benign schwannoma is associated with a favorable outcome. To our knowledge, there are case reports of schwannoma with CT and magnetic resonance imaging findings in the literature, although this is the first schwannoma case with PET-CT imaging.

    Congenital adrenal hyperplasia (CAH) is an autossomic recessive disorder caused by impaired steroidogenesis. Patients with CAH may present adrenal insufficiency with or without salt-wasting, as well as various degrees of virilization and fertility impairment, carrying a high incidence of testicular adrenal rest tumors and increased incidence of adrenal tumors. The diagnosis of CAH is made based on the adrenocortical profile hormonal evaluation and genotyping, in selected cases. Follow-up is mainly based on hormonal and clinical evaluation. Utility of imaging in this clinical setting may be helpful for the diagnosis, management, and follow-up of the patients, although recommendations according to most guidelines are weak when present. Thus, the authors aimed to conduct a narrative synthesis of how imaging can help in the management of patients with CAH, especially focused on genitography, ultrasonography, computed tomography, and magnetic resonance imaging.

A CT-scan guided needle biopsy revealed diffuse large- B cell lymphoma. The absence of pathological findings in clinical, bone marrow and CT scan examinations supported the diagnosis of primary non-Hodgkin Lymphoma of the adrenal glands. The patient was treated with four cycles of R-CHOP chemotherapy with Rituximab, liposomal Doxorubicin, Cyclophosphamide, Vincristine and Prednisolone. At the end of fourth cycle there was radiological improvement but the chemotherapy was stopped because of IV grade toxicity. He completed treatment with radiotherapy of right adrenal mass. Few days after finishing radiation therapy the patient died due to a disseminated infection. No progressive disease was founded.

    Systemic administration of endotoxin, which closely mimics the bacteria-induced systemic inflammatory response syndrome (SIRS) can ultimately lead to organ failure. Adrenal gland insufficiency is frequently diagnosed in critically ill patients; however, the underlying mechanisms are still unclear. In the present study, we studied comprehensively the characteristics of adrenal gland dysregulation, including inflammation, leukocyte infiltration and cell death in the adrenal glands in the course of LPS-induced systemic inflammation in mice. LPS enhanced expression of many proinflammatory cytokines, chemokines and adhesion molecules, which resulted in rapid recruitment of leukocytes into the adrenal gland. Furthermore, LPS-mediated inflammation was associated with increased apoptosis of adrenocortical and chromaffin cells. Our results performed in mice, suggest that LPS-induced adrenal gland inflammation and cell death might be mechanisms potentially involved in the adrenal gland dysfunction in patients with sepsis.

  2. Contemporary adrenal scintigraphy

    International Nuclear Information System (INIS)

    High-resolution computed tomography (CT) and magnetic resonance (MR) imaging have replaced scintigraphy as primary imaging modalities for the evaluation of adrenal diseases. Thin-slice CT, CT contrast washout studies and MR pulse sequences specifically designed to identify adrenal lipid content have radically changed the approach to anatomic imaging and provide unique insight into the physical characteristics of the adrenals. With a confirmed biochemical diagnosis, further evaluation is often unnecessary, especially in diagnostic localization of diseases of the adrenal cortex. However, despite the exquisite detail afforded by anatomy-based imaging, there are not infrequently clinical situations in which the functional insight provided by scintigraphy is crucial to identify adrenal dysfunction and to assist in localization of adrenocortical and adrenomedullary disease. The introduction of hybrid PET/CT and SPECT/CT, modalities that directly integrate anatomic and functional information, redefine the radiotracer principle in the larger context of high-resolution anatomic imaging. Instead of becoming obsolete, scintigraphy is an element of a device that combines it with CT or MR to allow a direct correlation between function and anatomy, whereby the combination creates a more powerful diagnostic tool than the separate component modalities.

    The impact of genetics and genomics on clinical medicine is becoming more and more important. Endocrinology pioneered the development of molecular medicine, but also the study of adrenal tumors had a great impact in this field. Particularly important was the detection of genetics of tumors derived from the adrenal medulla, as well as that of those derived from the sympathetic and parasympathetic paraganglia. The identification of mutations in one of the several pheochromocytoma/paraganglioma susceptibility genes may indicate a specific clinical management drive. Less well understood is the genetics of adrenal cortex tumors, in particular adrenocortical carcinoma, a rare and particularly aggressive disease. There are only a few examples of hereditary transmission of adrenocortical carcinoma, but the analysis of low penetrance genes by genome wide association study may enable us to discover new genetic mechanisms responsible for adrenocortical-derived tumors.

    Full Text Available Abstract Introduction Familial Mediterranean fever is an autosomal recessive disease that predominantly affects people of the Mediterranean coast. One of the most frequent complications of the disease is amyloidosis. This clinical entity is known as secondary (also called AA amyloidosis. Case presentation In this report, we describe the case of a 33-year-old Turkish man with familial Mediterranean fever and chronic renal insufficiency. He was admitted to our clinic with symptoms of suprarenal insufficiency. The patient died three months later as a result of cardiac arrest. Conclusion Our aim is to make a contribution to the literature by reporting a case of combined insufficiency due to the accumulation of renal and adrenal amyloid in a patient with familial Mediterranean fever, which has very rarely been described in the literature. We hope that adrenal insufficiency, which becomes fatal if not diagnosed and treated rapidly, will come to mind as easily as chronic renal failure in clinical practice.

    The nuclear receptor transcription factors DAX-1 (NR0B1) and SF-1 (NR5A1) regulate many aspects of adrenal and reproductive development and function. Disruption of the genes encoding these factors can be associated with pediatric adrenal disease. DAX-1 mutations are classically associated with X-linked adrenal hypoplasia congenita, hypogonadotropic hypogonadism and impaired spermatogenesis. However, other phenotypes are also being reported, such as isolated mineralocorticoid insufficiency, premature sexual development, primary adrenal insufficiency in a 46, XX patient and late-onset X-linked adrenal hypoplasia congenita and/or hypogonadotropic hypogonadism. SF-1 mutations have also been associated with primary adrenal insufficiency, together with 46, XY disorders of sex development. However it is emerging that SF-1 changes are a relatively rare cause of primary adrenal failure in humans, and most individuals with SF-1 mutations have a spectrum of 46, XY disorders of sex development phenotypes. These conditions range from 46, XY females with streak gonads and müllerian structures, through children with ambiguous genitalia and inguinal testes, to severe penoscrotal hypospadias with undescended testes. Therefore, the human gonad appears to be more sensitive than the adrenal gland to loss of SF-1 function. This review will focus on the expanding range of phenotypes associated with DAX-1 and SF-1 mutations.

    Full Text Available Abstract We report on a 14 year old boy who presented with the symptoms abdominal pain, fever and proteinuria. A hematoma in the region of the right pararenal space was diagnosed. Prothrombin time and activated partial thromboplastin time were prolonged, lupus anticoagulant and anticardiolipin antibodies were positive and serum cortisol was normal. Ten days after admission the boy suddenly suffered generalized seizures due to low serum sodium. As well, the patient developed hemolytic anemia, acute elevated liver enzymes, hematuria and increased proteinuria. At this time a second hemorrhage of the left adrenal gland was documented. Adrenal function tests revealed adrenal insufficiency. We suspected microthromboses in the adrenals and secondary bleeding and treated the boy with hydrocortisone, fludrocortisone and phenprocoumon. Conclusion Adrenal failure is a rare complication of APS in children with only five cases reported to date. As shown in our patient, this syndrome can manifest in a diverse set of simultaneously occurring symptoms.

    The past decade has seen significant advances in our understanding of the genetic aetiology of several forms of adrenal failure that present in infancy or childhood. Several of these disorders affect adrenal development and are termed 'adrenal hypoplasia'. These conditions can be broadly divided into: (1) secondary forms of adrenal hypoplasia due to panhypopituitarism (e.g. HESX1, LHX4, SOX3) or abnormalities in ACTH synthesis (TPIT) or processing (e.g. POMC or PC1); (2) adrenal hypoplasia as part of an ACTH resistance syndrome [MC2R/ACTH receptor, MRAP, AAAS (triple A syndrome)], and (3) primary defects in the development of the adrenal gland itself (primary adrenal hypoplasia). Primary adrenal hypoplasia most commonly occurs in an X-linked form due to mutations in the nuclear receptor DAX1 (NR0B1) but can occur in a poorly understood recessive form or as part of the IMAGe (intrauterine growth retardation, metaphyseal dysplasia, adrenal hypoplasia, genitourinary anomalies) syndrome. Defining the molecular basis of these conditions can have significant clinical implications for management, counselling and presymptomatic diagnosis, as well as providing fascinating insight into normal and abnormal mechanisms of adrenal development in humans.

    Full Text Available Background: Adrenal insufficiency has been reported in 46 % to 81.5 % of children receiving corticosteroids for acute lymphoblastic leukemia (ALL. Methodology: To assess the frequency of such insufficiency, 40 patients under 18 years (mean: 8.5 years with new diagnosis of ALL were studied. Base-line cortisol and adrenocorticotropin (ACTH levels were measured, and they received 5-week therapy with prednisolone. After 3 days off-steroid therapy, a stimulation test with ACTH 1 μg was done. In patients with abnormal cortisol (<18 μg/dL new ACTH tests were done and cortisol levels were determined at days 7, 14 and 30 until cortisol post-stimulation levels were normal. Results: Three days after the last steroid dose 29/40 (72.5 % had adrenal insufficiency after ACTH stimulus. At day 30 no one had abnormal cortisol levels after ACTH stimulus. All patients with adrenal suppression were over 5 years (HR 4.69; CI95 %: 1.44-15.32; p = 0.011. Conclusion: Steroids used during ALL treatment may cause adrenal insufficiency. Patients over 5 years are at high risk of developing adrenal suppression. We suggest to follow-up those patients with stress episodes after induction chemotherapy as steroid supplementation may be indicated.

    2016-01-01

    Primary adrenal hypercortisolism is mainly due to cortisol-producing adrenocortical adenomas, bilateral micronodular or macronodular disease, and adrenal carcinomas. Important advances in the pathophysiology of primary adrenal hypercortisolism have been made in the last few years, partly through the use of new molecular biology tools. Most adrenal abnormalities leading to increased cortisol production involve somatic or germinal mutations of genes encoding elements of the cyclic AMP/protein kinase A signaling pathway, as shown in adrenal adenomas in 2014. One peculiar condition is primary macronodular adrenal hyperplasia (PMAH), which has given rise to new pathophysiological concepts such as regulation of cortisol secretion by illegitimate ligands through aberrant expression of G protein-coupled transmembrane receptors in adrenal nodules and stimulation of cortisol production by local adrenocorticotropic hormone production through autocrine/paracrine mechanisms. These findings provide a basis for the development of targeted therapies as an alternative to surgery. The recent identification of germinal mutations of ARMC5 in PMAH raises the possibility that this is much more frequently an inherited disease than previously suspected. It also offers the possibility of earlier diagnosis of PMAH by genetic screening and, hopefully, of earlier intervention to prevent the onset of hypercortisolism and its complications. The pathophysiology of Cushing's syndrome associated with a subset of adrenal adenomas, including subclinical cortisol-secreting incidentalomas and adrenal carcinomas, remains to be determined.

    The authors report on the method of determination of the weight indices of the adrenyl gland glomerular, testicular-reticular and medullar zones with a spheroid shape; it is substantiated by mathematical analysis of a plasticine model of the adrenal gland, whose characteristics approached the actual ones. The method was particularly accurate in determination of the weight of the fascicular-reticular and glomerular zones, and less--in determination of the weight of the medullary layer, the method's error being 0.6-0.9% in the first case, 2.7-3.5% in the second and 5.3-6.4 in the last.

    Purpose. To evaluate the diagnosis and treatment of adrenal incidentalomas. Methods. One hundred and twenty-six patients with incidentalomas were analyzed, among them 98 underwent operation. Results. Eighty-eight of the adrenal incidentalomas were discovered by ultrasound. Of all the types of adrenal incidentalomas, 52 (41.3%) of them were adenomas; 43 (34.1%) were hypersecretory adrenal tumors, including 29 pheochromocytomas, 9 primary aldosteronisms, 1 adrenogenitol syndrome combined with adrenal adenoma, 2 Cushing's syndrome combined with adenomas and 2 Cushing's syndrome combined with nodular hyperplasias. All nonhypersecretory adrenal adenomas were under 6 cm, and all adrenal carcinomas were above 6 cm.Conclusions. To search for hypersecretory adrenal tumors and to detect malignant adrenal tumors are quite essential in the process of diagnosing adrenal incidentalomas. For nonhypersecretory adrenal adenomas, the size of tumor is the most important index in determining whether the tumor is benign or malignant and whether the tumor needs to be treated with operation.

  20. Adrenal Disorders and the Paediatric Brain: Pathophysiological Considerations and Clinical Implications

    Directory of Open Access Journals (Sweden)

    Full Text Available Various neurological and psychiatric manifestations have been recorded in children with adrenal disorders. Based on literature review and on personal case-studies and case-series we focused on the pathophysiological and clinical implications of glucocorticoid-related, mineralcorticoid-related, and catecholamine-related paediatric nervous system involvement. Childhood Cushing syndrome can be associated with long-lasting cognitive deficits and abnormal behaviour, even after resolution of the hypercortisolism. Exposure to excessive replacement of exogenous glucocorticoids in the paediatric age group (e.g., during treatments for adrenal insufficiency has been reported with neurological and magnetic resonance imaging (MRI abnormalities (e.g., delayed myelination and brain atrophy due to potential corticosteroid-related myelin damage in the developing brain and the possible impairment of limbic system ontogenesis. Idiopathic intracranial hypertension (IIH, a disorder of unclear pathophysiology characterised by increased cerebrospinal fluid (CSF pressure, has been described in children with hypercortisolism, adrenal insufficiency, and hyperaldosteronism, reflecting the potential underlying involvement of the adrenal-brain axis in the regulation of CSF pressure homeostasis. Arterial hypertension caused by paediatric adenomas or tumours of the adrenal cortex or medulla has been associated with various hypertension-related neurological manifestations. The development and maturation of the central nervous system (CNS through childhood is tightly regulated by intrinsic, paracrine, endocrine, and external modulators, and perturbations in any of these factors, including those related to adrenal hormone imbalance, could result in consequences that affect the structure and function of the paediatric brain. Animal experiments and clinical studies demonstrated that the developing (i.e., paediatric CNS seems to be particularly vulnerable to alterations induced by

  1. Computed tomographic findings of radiation-induced acute adrenal injury with associated radiation nephropathy: a case report

    International Nuclear Information System (INIS)

    Radiation nephropathy was first recognized in 1906. The kidney is a radiosensitive organ with a tolerance dose (5% complications in 5 years) of 20 Gray. The imaging findings of acute and chronic radiation induced renal injury are previously described. Radiation-induced adrenal injury, to our knowledge, has not been described in the literature. Unlike the kidneys and other upper abdominal organs, the adrenal glands are traditionally thought to be radio-resistant, protected from radiation-induced injury by proximity to adjacent organs and by the adrenal medulla which reportedly has increased radio-resistance. We present the computed tomographic imaging findings of a patient with acute radiation induced adrenal injury which resulted in adrenal insufficiency following radiotherapy of an adjacent thecal metastasis

  2. New insights into the controversy of adrenal function during critical illness.

    2015-10-01

    Critical illness represents a life-threatening disorder necessitating recruitment of defence mechanisms for survival. Herein, the hypothalamic-pituitary-adrenal axis is essential. However, the relevance of a relative insufficiency of the hypothalamic-pituitary-adrenal axis in critical illness, which is diagnosed by a suppressed cortisol response to exogenous adrenocorticotropic hormone (ACTH) irrespective of the plasma cortisol concentration, is controversial. Findings from several studies have provided insights that clarify at least part of this controversy. Rather than an activated hypothalamic-pituitary-adrenal axis, ACTH-independent regulators have been reported to contribute to increased cortisol availability during critical illness. One of these regulators is reduced cortisol breakdown, mediated by suppressed expression and activity of cortisol metabolising enzymes in the liver and kidneys. This downstream mechanism increases concentrations of plasma cortisol, but the ensuing feedback-inhibited ACTH release, when sustained for more than 1 week, has been shown to negatively affect adrenocortical integrity and function. Reduced adrenocortical ACTH signalling could explain reduced cortisol responses to exogenous ACTH. Whether such reduced cortisol responses in the presence of raised plasma (free) cortisol identifies adrenal failure needing treatment is unlikely. Additionally, reduced cortisol breakdown affects the optimum dose of hydrocortisone treatment during critical illness. Identification of patients with an insufficient hypothalamic-pituitary-adrenal axis response and the optimum treatment for this disorder clearly need more well designed preclinical and clinical studies.

  3. Radiological diagnosis of adrenal lesions

    International Nuclear Information System (INIS)

    Among all the radiological examination techniques, CT is today, besides scintigraphy, the method of choice as far as the detection of functional adrenal lesions is concerned. In primary aldosteronism, CT classification of the syndrome is based on the detection of an adenoma which can be reliably detected in adenoma sizes up to 8-10 mm. Thus, 70 to 80% of Conn's syndromes can be classified. In adrenal Cushing's syndrome, the distinction between adenoma and carcinoma of the adrenal gland is up to CT and can usually be easily made due to the characteristic morphology of each type of lesion. In case of a typcial adrenal or juxtaadrenal tumor location, detection of a pheochromocytoma is likewise easy. In ectopic and multiple pheochromocytomas or such as occur as part of a MEN-syndrome, the situation is quite different. If lesions of the adrenal gland are found by accident in examinations otherwise indicated, the question arises whether the process is malignant or benign. In this respect, all the traditional imaging methods, including CT, involve a considerable factor or uncertainity, especially if a malignant tumor is anamnestically known and the question of metastases arises. According to recent information, MR-imaging seems to be advantageous concerning this difficult differential diagnosis. (orig.)

  9. Control of adrenal androgen production.

    Science.gov (United States)

    Odell, W D; Parker, L N

    The major adrenal androgens are dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulphate (DHEAS) and androstenedione (delta 4). Studies by Cutler et al in 1978 demonstrated that these androgens are detectable in blood of all domestic and laboratory animals studied, but that only 4 species show increase in one or more with sexual maturation: rabbit, dog, chimpanzee and man. Studies by Grover and Odell in 1975 show these androgens do not bind to the androgen receptor obtained from rat prostate and thus probably are androgens only by conversion to an active androgen in vivo. Thomas and Oake in 1974 showed human skin converted DHEA to testosterone. The control of adrenal androgen secretion is in part modulated by ACTH. However, other factors or hormones must exist also, for a variety of clinical observations show dissociation in adrenal androgen versus cortisol secretion. Other substances that have been said to be controllers of adrenal androgen secretion include estrogens, prolactin, growth hormone, gonadotropins and lipotropin. None of these appear to be the usual physiological modulator, although under some circumstances each may increase androgen production. Studies from our laboratory using in vivo experiments in the castrate dog and published in 1979 indicated that crude extracts of bovine pituitary contained a substance that either modified ACTH stimulation of adrenal androgen secretion, or stimulated secretion itself - Cortisol Androgen Stimulating Hormone. Parker et al in 1983 showed a 60,000 MW glycoprotein was extractable from human pituitaries, which stimulated DHA secretion by dispersed canine adrenal cells in vitro, but did not stimulate cortisol secretion. This material contained no ACTH by radioimmunoassay. In 1982 Brubaker et al reported a substance was also present in human fetal pituitaries, which stimulated DHA secretion, but did not effect cortisol. PMID:6100259

    Background It is known that the hypothalamic-pituitary-adrenal (HPA) axis is highlighted by stimulation, such as sepsis,trauma, etc, when corticortropin increases and plasma cortisol levels enhance. Relative adrenal insufficiency is not uncommon in critically ill patients and may occur in severe sepsis patients with high plasma cortisol levels. It has been demonstrated that a short corticotropin test has a good prognostic value and is helpful in identifying patients with septic shock at high risk for death, but it has not been established for all severe sepsis patients, especially in China. The aim of this study is to explore the relationship between adrenal function and prognosis in patients with severe sepsis.Methods This prospective study was conducted between July and December 2004 in 6 teaching hospitals. Two hundred and forty patients with severe sepsis were enrolled in this study. A short corticotropin stimulation test was performed in all patients by intravenous injection of 250 μg of corticotropin. Blood samples were taken immediately before the test (T0), 30 (T30) and 60 (T60) minutes afterward, and the plasma cortisol concentration was measured by radio-immunoassay. At the onset of severe sepsis, the following parameters were recorded: age, sex, Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ, heart rate, mean arterial pressure (MAP), arterial partial pressure of oxygen (PaO2)/fraction of inspired oxygen (FiO2), peripheral blood of hemoglobin, platelets and leukocyte concentration and the number of organ failure. Patients were designated into two groups (survival and non-survival groups) according to the 28-day mortality. Relative adrenal insufficiency was defined as the difference between T0 and the highest value of T30 or T60 (△Tmax) ≤9 μg/dl.Results (1) Two hundred and forty patients with severe sepsis were included in this study, with 134 patients in the survival group and 106 in the non-survival group.

    Full Text Available We report on a patient with genetically confirmed adrenal hypoplasia congenita (AHC whose presentation and laboratory abnormalities were consistent with the more common condition, congenital adrenal hyperplasia (CAH. The patient presented with failure to thrive and salt wasting. General appearance showed marked hyperpigmentation and normal male genitalia. He displayed mildly elevated 17-hydroxyprogesterone and markedly elevated 11-deoxycortisol levels at baseline and with ACTH stimulation testing. Results were consistent with 11β-hydroxylase deficiency. He required glucocorticoids and high doses of mineralocorticoids. The marked elevation in 11-deoxycortisol directed our clinical reasoning away from a hypoplastic condition and towards a hyperplasic adrenal condition. Sequencing of the DAX1 gene (named for dosage-sensitive sex reversal (DSS locus and the AHC locus on the X chromosome revealed a missense mutation. A review of the literature revealed that elevated 11-deoxycortisol levels have been noted in kindreds with DAX1 mutations, but only when measured very early in life. A mouse model has recently been described that displays elevated 11-deoxycorticosterone levels and evidence for hyperplasia of the zona glomerulosa of the adrenal gland. We conclude that DAX1 testing may be considered in patients with laboratory evidence of 11β-hydroxylase deficiency, especially in those with severe salt wasting.

    Endoscopic ultrasound (EUS) imaging of adrenal glands and its application to diagnostic procedures of adrenal diseases has been reported since 1998. It can be considered a relevant advantage in the field of adrenal diseases. Indeed, EUS allows the detection of adrenal lesions (even very small ones) and their characterization, the assessment of malignancy criteria, the early detection of neoplastic recurrences, the preoperative identification of morphologically healthy parts of the glands, the differentiation of extra-adrenal from adrenal tumors, and of the pathological entities associated with adrenal insufficiency, and the fine-needle aspiration biopsy (EUS-FNA) of suspicious lesions. At the same time, its clinical relevance depends on the experience of the endosonographer. Moreover, EUS is also by far the best and most sensitive imaging technique to detect and assess the follow-up of pancreatic manifestation of MEN1 disease. It furthermore enables the preoperatively localization of insulinomas and critical structures in their neighborhood, and may be relevant in planning surgical strategy. A positive EUS in a case of insulinoma furthermore confirms the endocrine diagnosis, especially considering the differential diagnosis of hypoglycemia factitia by oral antidiabetics. It can be supplemented by EUS-FNA. Again, it has to be considered that EUS may reveal false positive and false negative results, and the quality of the findings largely depends on the endosonographer's skills and experience. The most important technical details together with the advantages and limitations of EUS, and the pathognomonic characteristic of benign and malignant disorders of the adrenals and pancreas are presented here.

    The pathologies of the adrenal cortex -adrenal insufficiency and Cushing syndrome- have their origin on the deficit or hypersecretion of some of the hormones that are secreted by the adrenal cortex, which is divided in three zones anatomically defined: the external zone, also called the zona glomerulosa, which is the main production site of aldosterone and mineralocorticoids; the internal zone, or zona reticularis, that produces androgens; and the external zone, or zone 1 orticotrop, which is responsible for producing glucocorticoids. In this work, a quantitative analysis of those hormones and their pathologic trigger was made; the quantification was made in the laboratory by means of highly sensitive and specific techniques, in this case, the radioimmunoassay, in which a radioisotope I-125 is used. This technique is based on the biochemical bond-type reaction, because it requires of a substance called the linker, which bonds to another called ligand. This reaction is also known as antigen-antibody (Ag-Ab), where the results of the reaction will depend on the quantity of antigen in the sample and on its affinity for the antibody. In this work, a 56 patients (of which 13 were men and 43 women) study was made. The cortisol, the ACTH, the androsterone and the DHEA values were very elevated in the majority of the cases corresponding to women, predominating cortisol; while in men, a notorious elevation of the 17 {alpha}-OH-PRG and of the DHEA-SO{sub 4} was observed. Based on that, we can conclude that 51 of them did not have mayor complications, because they just went to the laboratory once, while the remaining 5 had a medical monitoring, and they visited the laboratory more than one occasion, tell about a difficulty on their improvement. According to the results, an approximate relation of 8:2 women:men, respectively, becomes clear to the hormonal pathologies of the adrenal cortex. (Author)

    Full Text Available Heart failure (HF is a chronic clinical syndrome characterized by the reduction in left ventricular (LV function and it represents one of the most important causes of morbidity and mortality worldwide. Despite considerable advances in pharmacological treatment, HF represents a severe clinical and social burden. Sympathetic outflow, characterized by increased circulating catecholamines (CAs biosynthesis and secretion, is peculiar in HF and sympatholytic treatments (as β-blockers are presently being investigated for the treatment of this disease. Adrenal gland secretes Epinephrine (80% and Norepinephrine (20% in response to acetylcholine stimulation of nicotinic cholinergic receptors on the chromaffin cell membranes. This process is regulated by adrenergic receptors (ARs: α2ARs inhibit CA release through coupling to inhibitory Gi-proteins, and βARs (mainly β2ARs stimulate CA release through coupling to stimulatory Gs-proteins. All ARs are G-protein-coupled receptors (GPCRs and GPCR kinases (GRKs regulate their signaling and function. Adrenal GRK2-mediated α2AR desensitization and downregulation are increased in HF and seem to be a fundamental regulator of CA secretion from the adrenal gland. Consequently, restoration of adrenal a2AR signaling through the inhibition of GRK2 is a fascinating sympatholytic therapeutic strategy for chronic HF. This strategy could have several significant advantages over existing HF pharmacotherapies (antiadrenergic, such as bAR-blockers minimizing side-effects on extra-cardiac tissues and reducing the chronic activation of the renin–angiotensin–aldosterone and endothelin systems.The role of adrenal ARs in regulation of sympathetic hyperactivity opens interesting perspectives in understanding pathophysiology of HF and identifying new potential therapeutic targets.

    Adrenal - renal fusion is a rare entity defined as incomplete encapsulation of the adrenal gland and kidney with histologically adjacent functional tissue. This report describes the first published intraoperative identification of this anomaly during laparoscopic adrenalectomy. The patient was a 59-year-old man with chronic hypertension refractory to multiple antihypertensives found to be caused by a right-sided aldosterone-producing adrenal adenoma in the setting of bilateral adrenal hyperplasia. During laparoscopic adrenalectomy, the normal avascular plane between the kidney and adrenal gland was absent. Pathologic evaluation confirmed adrenal - renal fusion without adrenal heterotopia. Identified intraoperatively, this may be misdiagnosed as invasive malignancy, and thus awareness of this anomaly may help prevent unnecessarily morbid resection. PMID:26195881

    10 patients with adrenal damage were observed during 2.5 years. It amounted 0.93% of all patients with closed abdominal injuries. The right adrenal gland was traumatized in all cases evidently due to it's compression between right lobe of liver and vertebral column. Adrenal damage is observed quite often in combination with injuries of right liver lobe, right kidney and retroperitoneal hematoma formation. 5 patients underwent laparotomy on account of intra-abdominal bleeding, but adrenal damage was never revealed. Ultrasound and tomographic semiotics of adrenal damage was worked out, which allowed ascertaining diagnosis in 80% on application of ultrasound study and in 100% at computer tomography. Injury of one adrenal gland was not accompanied by adrenal failure and did not require hormonal replacement therapy.

    Pancreatic exocrine insufficiency is the most common cause of maldigestion in dogs. This is usually caused by irreversible atrophy of the pancreas which subsequently requires life-long substitution therapy. The pathophysiology, symptoms and diagnosis are briefly reviewed in the present paper. The Trypsin-like-immunoreactivity test is recommended for establishing the diagnosis. Finally, treatment and possible causes of the failure of therapy are discussed. PMID:2196714

    Intravascular large B-cell lymphoma (IVLBCL) is a rare subtype of malignant lymphoma. Although the involvement of adrenal glands in IVLBCL is often observed, primary adrenal IVLBCL is rare. Most reported cases of adrenal IVLBCL showed bilateral lesions resulting in rapidly progressive adrenal failure and poor prognosis. Here, we report a case of slowly progressive primary adrenal IVLBCL manifesting initially with unilateral adrenal incidentaloma. This case is a silent IVLBCL and shows that the enlargement of both adrenal glands can be followed.

  3. Low estriol levels in the maternal marker screen as a predictor of X-linked adrenal hypoplasia congenita: Case report

    Durković Jasmina

    2014-01-01

    Full Text Available Introduction. X-linked adrenal hypoplasia congenita (AHC is a rare cause of adrenocortical insufficiency. Early postnatal diagnosis may prevent severe hypoglycemia, Addisonian crises and death. Low maternal estriol (E3 levels in the second trimester of pregnancy could indicate the possibility that the fetus suffers from a disorder that causes adrenal insufficiency. Suspicion is based on the fact that E3 originates from dehydroepiandrosterone (DHEA synthesized in the fetal adrenals. In case of adrenal insufficiency, the impaired production of fetal DHEA leads to a subsequent reduction of E3 concentrations in maternal serum. There are only a few reports of AHC suspected prenatally due to low maternal E3 levels. Case Outline. We describe two brothers with adrenal insufficiency due to AHC. The older brother was admitted to the hospital at the age of 33 days due to failure to thrive, vomiting, and dehydration. Genetic analysis revealed a hemizygous mutation in DAX-1 gene, thus confirming the diagnosis of ACH. The same mutation was detected in his mother. In the second pregnancy, E3 concentrations were determined from maternal serum. Estriol levels during the second trimester were extremely low suggesting the diagnosis of AHC. The diagnosis was confirmed during the neonatal period by genetic testing, and replacement therapy was started at the age of 10 days. This boy never experienced an adverse episode such as hypoglycemia or adrenal crises. Conclusion. Since determination of E3 is a simple, sensitive, noninvasive and cheap method, its use as an obligatory prenatal screening test should be accepted as a standard practice in Serbia.

    We report a rare case of bilateral primary adrenal non-Hodgkin's lymphoma with adrenal failure. A 66-year-old woman developed symptoms of adrenal failure. The cause of adrenal failure was suspected to be malignant lymphoma based on the high levels of serum soluble interleukin-2 receptor and LDH. Bilateral adrenalectomy was performed and pathological examination showed intravascular large B-cell lymphoma (IVL). Although complete remission was achieved, recurrence occurred three months later with brain metastases. IVL should be suspected in patients with bilateral adrenal tumors who present with rapidly progressive adrenal failure.

  8. Bilateral adrenal haemorrhage secondary to intra-abdominal sepsis: a case report.

    LENUS (Irish Health Repository)

    Egan, Aoife M

    2012-01-31

    INTRODUCTION: Bilateral adrenal haemorrhage is a rare cause of adrenal failure. Clinical features are non-specific and therefore a high index of suspicion must be maintained in patients at risk. Predisposing factors include infection, malignancy and the post-operative state. CASE PRESENTATION: We report the case of a patient who underwent a left hemicolectomy with primary anastomosis and formation of a defunctioning loop ileostomy for an obstructing colon carcinoma at the splenic flexure. En-bloc splenectomy was performed to ensure an oncologic resection. The patient developed a purulent abdominal collection post-operatively and became septic with hypotension and pyrexia. This precipitated acute bilateral adrenal haemorrhage with consequent adrenal insufficiency. Clinical suspicion was confirmed by radiological findings and a co-syntropin test. Following drainage of the collection, antibiotic therapy and corticosteroid replacement, the patient made an excellent recovery. CONCLUSION: This case highlights the importance of prompt diagnosis and treatment of adrenal failure. In their absence, this condition can rapidly lead to death of the patient.

  9. Functional paraganglioma extra-adrenal

    International Nuclear Information System (INIS)

    Functioning paragangliomas are rare tumours that produce catecholamines.They originate from extra-adrenal chromaffin cells. They are frequently malignant and are associated with high incidence of persistent or recurrent disease after their primary treatment. They are known as glomus, chemodectomas, chromaffin paragangliomas and glomerulocytomas. The location is diverse and reflects the paragangliomar distribution in the body from the base of the skull to the pelvic floor. The paragangliomas are found where there are nodes of the autonomous system, however, approximately 90% of these tumours appear in the adrenal glands (and they constitute the pheochromocytomas) and the remaining 10% is a location extra adrenal, but it has been said that its impact can be underestimated, ranging from 18% to 22% in adults and children up to 30%. The extra-adrenal are originated more frequently in the abdomen (85%), other in the chest (12%) and more rarely in the head and neck (3%). Imaging studies and measurement of non-physiological production of catecholamines may aid in the diagnosis of this entity. Surgery is the treatment of choice. It is presented the case of a primigravidas patient aged 32 with HTAIE requiring caesarean section, who had a postpartum torpid and despite to multiple antihypertensive treatments their pathology was difficult to deal, with ophthalmic complications. Some time later, the patient is studied by hyperhidrosis, laboratory tests and images are requested and it is documented incidentally, a left retroperitoneal tumour, the studies are expanded and reach the correct diagnosis. The tumour required surgical resection. The patient had a satisfactory postoperative period and she discharged with control in the external consultation. (author)

    Background and Objectives: Schwannomas are tumors originating from Schwann cells of the peripheral nerve sheath (neurilemma) of the neuroectoderm. Rarely, schwannomas can arise from the retroperitoneum and adrenal medulla. We describe a case of a 71-y-old woman who presented with an incidentally discovered adrenal tumor. Methods: Ultrasound and computed tomography scans revealed a lesion with solid and cystic areas originating from the left adrenal gland. The patient underwent complete laparoscopic resection of the tumor and the left adrenal gland. Results: Histopathological examination and immunohistochemical staining of the excised specimen revealed a benign schwannoma measuring 5.5×5×3.7 cm. To our knowledge, few other cases of laparoscopic resection of adrenal schwannomas have been reported. Conclusion: Because preoperative diagnosis of adrenal tumors is inconclusive, complete laparoscopic excision allows for definitive diagnosis with histological evaluation and represents the treatment of choice.

    Full Text Available Adrenal cysts are rare, and their clinical management remains controversial. We report a case involving an adrenal cyst with a complicated appearance on radiological studies. Unenhanced computed tomography revealed a unilocular, noncalcified, hypoattenuating mass with a thin wall in the left adrenal gland. The lesion gradually increased in size from 10 to 50 mm at two-year follow-up. On contrast-enhanced magnetic resonance imaging, a mural nodule with contrast enhancement was observed. The entire adrenal gland was excised en bloc via a lateral transperitoneal laparoscopic approach without violating the principles of surgical oncology. The pathological diagnosis was an adrenal pseudocyst. Laparoscopic adrenalectomy is a safe option for the treatment of complex adrenal cysts, while maintaining the benefits of minimal invasiveness.

  18. Diagnosis of adrenal tumors with radionuclide imaging

    International Nuclear Information System (INIS)

    The development of radiolabeled cholesterols in 1969 as precursors of adrenocortical steroid production allowed the first noninvasive imaging of the adrenal cortices. FDA-NDA approval in 1984 should allow routine use of these agents in most hospitals. NP-59 is most commonly used in the diagnosis and management of Cushing syndrome; the second most common use is in the diagnosis of primary aldosteronism. It is also helpful in the differential diagnosis of adrenal and ovarian hyperandrogenism and hirsutism, and is the only noninvasive method of detecting unilateral adrenocortical hypofunction. The newest and most popular use is in the differential diagnosis of asymptomatic masses in the region of the adrenal gland discovered incidentally with CT scan (incidentalomas). In this situation, the NP-59 scan can define whether the tumor is in the adrenal gland and if it is functional or nonfunctional. The authors believe that, in the future, radiolabeled enzyme inhibitors might offer better diagnostic imaging of the adrenal cortex, although these agents will probably not be available for routine use for some time. The development of a radioiodinated guanethidine analog, 131I-MIBG, has allowed differentiation of normal adrenal medullary function from bilateral adrenal medullary hyperplasia before the development of hypertension or tachycardia, diagnostic increases in plasma or urinary catecholamines, or abnormal CT scans. The search for a pheochromocytoma should begin with 131I-MIBG scintigraphy. While over 90% of primary pheochromocytomas occur in the abdomen, neither a survey of the abdomen nor the finding of a single tumor should conclude the search

  19. Clinicopathological correlates of adrenal Cushing's syndrome.

    Endogenous Cushing's syndrome is a rare endocrine disorder that incurs significant cardiovascular morbidity and mortality, due to glucocorticoid excess. It comprises adrenal (20%) and non-adrenal (80%) aetiologies. While the majority of cases are attributed to pituitary or ectopic corticotropin (ACTH) overproduction, primary cortisol-producing adrenal cortical lesions are increasingly recognised in the pathophysiology of Cushing's syndrome. Our understanding of this disease has progressed substantially over the past decade. Recently, important mechanisms underlying the pathogenesis of adrenal hypercortisolism have been elucidated with the discovery of mutations in cyclic AMP signalling (PRKACA, PRKAR1A, GNAS, PDE11A, PDE8B), armadillo repeat containing 5 gene (ARMC5) a putative tumour suppressor gene, aberrant G-protein-coupled receptors, and intra-adrenal secretion of ACTH. Accurate subtyping of Cushing's syndrome is crucial for treatment decision-making and requires a complete integration of clinical, biochemical, imaging and pathology findings. Pathological correlates in the adrenal glands include hyperplasia, adenoma and carcinoma. While the most common presentation is diffuse adrenocortical hyperplasia secondary to excess ACTH production, this entity is usually treated with pituitary or ectopic tumour resection. Therefore, when confronted with adrenalectomy specimens in the setting of Cushing's syndrome, surgical pathologists are most commonly exposed to adrenocortical adenomas, carcinomas and primary macronodular or micronodular hyperplasia. This review provides an update on the rapidly evolving knowledge of adrenal Cushing's syndrome and discusses the clinicopathological correlations of this important disease.

  20. Normal dexamethasone-suppression adrenal scintiscan

    International Nuclear Information System (INIS)

    To establish the parameters of adrenal imaging under dexamethasone suppression (DS), 18 normotensive, normal male volunteers underwent dexamethasone-suppression adrenal scintiscanning. Five control groups were established and given dexamethasone, either 8 mg for 2 days or 4 mg for 7 days before 6β-[1311]iodomethyl-norcholesterol (NP-59) administration. NP-59 was given in doses of 2, 1, or 0.5 mCi. Early visualization (3-5 days) of the adrenals was noted in the groups on the 8 mg DS regimen with either 1 or 2 mCi of NP-59. Late visualization (5-7 days) was noted in the groups that received 4 mg DS and either 2, 1, or 0.5 mCi of MP-59, respectively. The normal adrenal will demonstrate uptake of NP-59 under DS, and the duration of DS before imaging is the critical factor as to when discernible adrenal visualization will occur. The documentation of the normal suppression interval on these DS regimens provides a basis for the correct diagnostic interpretation of adrenal hyperfunction as seen on the dexamethasone-suppression NP-59 adrenal scan

    Intra-abdominal hypertension and abdominal compartment syndrome (IAH/ACS) are life-threatening conditions and caused by several clinical status. Although there is insufficient data regarding its effects on adrenal glands. This study aimed to identify whether elevated intra-abdominal pressure (IAP) caused any alteration on the morphology and function of adrenal glands in a rat model. Twenty four Sprague-Dawley male rats were included in the study. Animals were allocated into 4 groups. IAP was elevated to 15 mmHg for one hour and four hours in group 2 and 4. Group 1 and 3 were sham groups. Blood samples were taken for the assessment of plasma adrenaline, noradrenaline, and corticosterone levels and adrenalectomies were performed to evaluate apoptosis. Blood adrenaline, noradrenaline and corticosterone levels were significantly higher in the study groups compared with the sham groups. However, there were no significant changes in apoptotic index scores in the study groups as compared to sham groups. These results support that increased IAH leads to discharge of catecholamine and corticosterone from the adrenal glands. Failure to demonstrate similar changes in apoptotic index score may be concluded as apoptosis is not a leading pathway for impairment of adrenal glands during IAH period.

    Weight loss following esophagectomy is a management challenge for all patients. It is multifactorial with contributing factors including loss of gastric reservoir, rapid small bowel transit, malabsorption, and adjuvant chemotherapy. The development of a postoperative malabsorption syndrome, as a result of exocrine pancreatic insufficiency (EPI), is recognized in a subgroup of patients following gastrectomy. This has not previously been documented following esophageal resection. EPI can result in symptoms of flatulence, diarrhea, steatorrhea, vitamin deficiencies, and weight loss. It therefore has the potential to pose a significant level of morbidity in postoperative patients. There is some evidence that patients with proven EPI (fecal elastase-1 PERT). We observed symptoms compatible with EPI in a subgroup of patients following esophagectomy. We hypothesized that this was contributing to malabsorption and malnutrition in these patients. To investigate this, fecal elastase-1 was measured in postoperative patients, and in those with proven EPI, a trial of PERT was commenced in combination with specialist dietary education. At routine postoperative follow-up, which included assessment by a specialist dietitian, those patients with symptoms suggestive of malabsorption were given the opportunity to have their fecal elastase-1 measured. PERT was then offered to patients with fecal elastase-1 less than 200 μg/g (EPI) as well as those in the 200-500 μg/g range (mild EPI) with more severe symptoms. Fecal elastase-1 was measured in 63 patients between June 2009 and January 2011 at a median of 4 months (range 1-42) following surgery. Ten patients had fecal elastase-1 less than 200 μg/g, and all had failed to maintain preoperative weight. All accepted a trial of PERT. Nine (90%) had symptomatic improvement, and seven (70%) increased their weight. Thirty-nine patients had a fecal elastase-1 in the 200-500 μg/g range. Twelve were given a trial of PERT based on level of

    Adrenal lesions in children may present with an asymptomatic adrenal mass lesion, an endocrinopathy, a hypertensive or metabolic crisis or a paraneoplastic syndrome. Some of the underlying disease processes remain localised within the adrenal gland or may develop into disseminated disease. The role of the radiologist is to confirm the adrenal location of a lesion and to document any other foci of disease. Ultrasound, CT, MR imaging and metaiodobenzylguanidine scintigraphy are the most commonly utilised imaging modalities for examining the adrenal glands and their pathologies in children. This paper reviews the spectrum of adrenal disease in childhood and presents the information as a series of radiological appearances: anomalies of adrenal shape, location, number and size, cystic adrenal masses, solid adrenal mass lesions, and adrenal calcifications are all examined. The radiological findings must always be interpreted in conjunction with the patient's age, the clinical history, the findings on physical examination and the available biochemical data. (orig.)

  5. Update on imaging diagnosis of adrenal tumors

    International Nuclear Information System (INIS)

    Imaging diagnosis of adrenal tumors is increasingly frequent. Characterization and differentiation of benign adenomas and malignant injures is very important, mainly in the patient with malignant or functioning disease. Computed tomography, magnetic resonance imaging and positron emission tomography/computed tomography allowed greater precision in characterizing and differentiating the adrenal masses in a non-invasive way. This review explained the physiological principles supporting these techniques, its advantages and restrictions. The main characteristics of the most frequent adrenal tumor images were described, in addition to submitting an algorithm for the use of these diagnostic means

    Brown widow spider (BrWS) (Latrodectus geometricus) venom produces intense systemic reactions such as cramps, harsh muscle nociceptive, nauseas, vomiting and hypertension. The proposed pathogenic mechanisms resulting in these accidents have principally been damages occurring at the nervous system. However, it is suspected that there is also damage of the adrenal glands, as a result of the experimental animal's clinical manifestations, which developed symptoms compatible with acute adrenal insufficiency. We have currently found that the adrenal gland is damaged by this venom gland homogenates (VGH) producing severe alterations on cortex cells resulting in death by acute adrenal insufficiency. In general, the ultrastructural study on the glands of mice under transmission electronic microscopy observations showed alterations in the majority of the intracellular membranes within 3 to 24h. BrWSVGH also showed specific actions on extracellular matrix proteins such as fibronectin, laminin and fibrinogen. In addition, zymogram experiments using gelatin as substrates detected gelatinolytic activity. The molecular exclusion fractionation of crude BrWSVGH resulted in 15 fractions, of which F1 and F2 presented alpha/beta-fibrinogenase and fibronectinolytic activities. Fractions F6, F14 and F15 showed only alpha-fibrinogenase activity; in contrast, the gelatinolytic action was only observed in fraction F11. Only metalloproteinase inhibitors abolished all these proteolytic activities. Our results suggest that adrenal cortex lesions may be relevant in the etiopathogenesis of severe brown widow spider envenoming. To our knowledge, this is the first report on adrenal gland damages, fibrinogenolytic activity and interrelations with cell-matrix adhesion proteins caused by L.geometricus VGH. The venom of this spider could be inducing hemostatic system damages on envenomed patients.

    Adrenal myelolipomas are infrequently encountered benign tumours of unknown aetiology. In the majority of cases they are unilateral, and clinically and hormonally silent, only requiring periodic follow-up. However, bilateral adrenal myelolipomas are sometimes associated with endocrine disorders and warrant appropriate evaluation. Though the understanding of the pathophysiology of adrenal myelolipomas has long been elusive, adrenocorticotropic hormone (ACTH) has been proposed as the main tropic factor in a number of studies. Cushing's disease is rarely associated with bilateral and sometimes giant myelolipomas. In this article, the association of bilateral adrenal myelolipomas with Cushing's disease has been discussed and the role of ACTH in the tumourigenesis has been reviewed.

    Adrenal hemorrhage (AH) is a well-described complication of the neonatal period, anticoagulant therapy, and overwhelming bacterial infection especially with N. meningitis. Until recently the diagnosis of acute AH was based predominantly on autopsy findings. Ultrasound and computed tomography examinations have been successfully used for antemortem detection of AH in neonates and anticoagulated patients. We report two patients with fulminant meningococcal infection who demonstrated bilateral adrenal hemorrhages on ultrasonography.

    Full Text Available Adrenal myelolipomas are rare benign tumors of the adrenal cortex composed of adipose and hematopoietic cells. They have been postulated to arise from repeated stimulation by stress, inflammation and ACTH oversecretion. Myelolipomas are usually detected incidentally on imaging and do not require any active intervention besides regular follow-up by imaging. However, myelolipomas may insidiously grow to large sizes and cause mass effects and hemorrhage. Timely diagnosis and surgical resection are curative and lifesaving.

    Full Text Available We report herein a case of idiopathic adrenal hematoma. A 59-year-old Japanese man was referred to our hospital for evaluation of a 7.0 cm mass in the right upper abdominal cavity. The tumor was suspected to originate from either the posterior segment of the liver or the right adrenal gland. His chief complaint was weight loss of 8 kg over the previous 6 months. He had no past medical history and took no medications, including no anticoagulants. Laboratory data were almost normal except for a slight elevation of PIVKA-II. The origin of the tumor was found to be the adrenal gland, as angiography revealed the blood supply to the mass to derive from the right superior and inferior adrenal arteries. A fine needle biopsy of the lesion was unable to confirm the diagnosis. Open right adrenalectomy was performed. The histopathological findings of the surgical specimen revealed a hematoma with normal adrenal tissue. In the absence of any obvious etiology, the diagnosis was idiopathic adrenal hematoma.

    Dopamine is known to play a role in the modulation of aldosterone and catecholamine secretion from the adrenal gland, where dopamine receptors (DR), in particular the DR type 2 (D(2)), have been found to be expressed. DR expression has also been demonstrated in some types of benign adrenal tumors. The aims of the current study were to evaluate DR expression and D(2) localization in the normal adrenal gland and in different types of benign and malignant adrenal tumors, as well as to evaluate the in vitro effects of the dopamine agonists bromocriptine and cabergoline on hormone secretion in nontumoral adrenal cells. Adrenal tissues from 25 patients, subjected to adrenal surgery for different diseases, were studied. These included three normal adrenals; five adrenal hyperplasias; four aldosterone-secreting, two cortisol-secreting, and two clinically nonfunctioning adrenal adenomas; two aldosterone-secreting, two cortisol-secreting, and two androgen-secreting adrenal carcinomas; and three pheochromocytomas. In all tissues, DR and D(2) isoform (D(2long) and D(2short)) expression was evaluated by RT-PCR. D(2) localization was also evaluated by immunohistochemistry using a specific polyclonal antibody, whereas D(2)-like receptor expression was evaluated by receptor-ligand binding study, using the radiolabeled D(2) analog (125)I-epidepride. The effects of bromocriptine and cabergoline on baseline and ACTH and/or angiotensin II-stimulated aldosterone, cortisol, and androstenedione secretion were evaluated in cell cultures derived from five different adrenal hyperplasia. At RT-PCR, both D(1)-like and D(2)-like receptors were expressed in all normal and hyperplastic adrenals. D(2) and D(4) were expressed in aldosterone- and cortisol-secreting adenomas, cortisol-secreting carcinomas, and clinically nonfunctioning adenomas, whereas no DR was expressed in aldosterone- and androgen-secreting carcinomas. D(2), D(4), and D(5) were expressed in pheochromocytomas. In all D(2

    Classic findings have demonstrated an important role for sex steroids as regulators of aggression, but this relationship is lacking within some environmental contexts. In mammals and birds, the adrenal androgen dehydroepiandrosterone (DHEA), a non-gonadal precursor of biologically active steroids, has been linked to aggression. Although females, like males, use aggression when competing for limited resources, the mechanisms underlying female aggression remain understudied. Here, we propose a previously undescribed endocrine mechanism regulating female aggression via direct action of the pineal hormone melatonin on adrenal androgens. We examined this in a solitary hamster species, Phodopus sungorus, in which both sexes are highly territorial across the seasons, and display increased aggression concomitant with decreased serum levels of sex steroids in short 'winter-like' days. Short- but not long-day females had increased adrenal DHEA responsiveness co-occurring with morphological changes in the adrenal gland. Further, serum DHEA and total adrenal DHEA content were elevated in short days. Lastly, melatonin increased DHEA and aggression and stimulated DHEA release from cultured adrenals. Collectively, these findings demonstrate that DHEA is a key peripheral regulator of aggression and that melatonin coordinates a 'seasonal switch' from gonadal to adrenal regulation of aggression by direct action on the adrenal glands.

    CT or MRI are utilized in the initial evaluation of adrenal incidentalomas; however, overlap exists between benign and malignant lesions on these examinations. The American College of Radiology recommends PET scans to complement CT and MRI for patients with adrenal masses and a moderate-to-high likelihood of neoplastic disease. We present images of a PET-avid adrenal lesion in a patient with pulmonary and pancreatic neoplasms that mimicked metastasis, but was found to be a benign adrenal hemangioma on surgical resection. The use of PET for adrenal tumors, specifically adrenal hemangiomas, will be reviewed. PMID:24089061

    The development of radiolabeled cholesterols in 1969 as precursors of adrenocortical steroid production allowed the first noninvasive imaging of the adrenal cortices. FDA-NDA approval in 1984 should allow routine use of these agents in most hospitals. NP-59 is most commonly used in the diagnosis and management of Cushing syndrome; the second most common use is in the diagnosis of primary aldosteronism. It is also helpful in the differential diagnosis of adrenal and ovarian hyperandrogenism and hirsutism, and is the only noninvasive method of detecting unilateral adrenocortical hypofunction. The newest and most popular use is in the differential diagnosis of asymptomatic masses in the region of the adrenal gland discovered incidentally with CT scan (incidentalomas). In this situation, the NP-59 scan can define whether the tumor is in the adrenal gland and if it is functional or nonfunctional. The authors believe that, in the future, radiolabeled enzyme inhibitors might offer better diagnostic imaging of the adrenal cortex, although these agents will probably not be available for routine use for some time. The development of a radioiodinated guanethidine analog, /sup 131/I-MIBG, has allowed differentiation of normal adrenal medullary function from bilateral adrenal medullary hyperplasia before the development of hypertension or tachycardia, diagnostic increases in plasma or urinary catecholamines, or abnormal CT scans. The search for a pheochromocytoma should begin with /sup 131/I-MIBG scintigraphy. While over 90% of primary pheochromocytomas occur in the abdomen, neither a survey of the abdomen nor the finding of a single tumor should conclude the search.

While most incidentalomas represent benign disease, typically an adenoma, the possibility of malignant involvement of the adrenal gland necessitates a reliance on imaging to inform management decisions. In this article, we review the literature on adrenal gland imaging, with particular emphasis on computed tomography, magnetic resonance imaging, and photon-emission tomography, and discuss how these findings relate to clinical practice. Emerging technologies, such as contrast-enhanced ultrasonography, dual-energy computed tomography, and magnetic resonance spectroscopic imaging will also be briefly addressed.

    Spontaneous Idiopathic Adrenal Haemorrhage (SIAH) is an unusual surgical emergency which can present with life threatening massive retroperitoneal bleeding. Most of the cases reported in the literature are associated with use of anticoagulation or underlying adrenal pathology such as tumors or cysts. Since this clinical entity is uncommon and clinical presentation is very indistinct, the diagnosis can be easily missed and can be challenging for the treating physicians. Nevertheless a raised clinical suspicion coupled with advances in radiological imaging have considerably improved the detection of SIAH in recent times. We report an unusual case of a 20 years old healthy female student who presented to our hospital with sudden onset of abdominal pain and shock. She was diagnosed as a case of massive spontaneous idiopathic unilateral adrenal haemorrhage, unaccompanied by any hematologic disorder, trauma or underlying pathology. Although patient was hemodynamically unstable at presentation, she was resuscitated promptly, investigated appropriately, hence recovered uneventfully with conservative management alone.

    It had been concluded by Scapagnini et al. (1971) that brain serotonin (5-HT) was involved in the regulation of the diurnal rhythm of the pituitary-adrenal system but not in the stress response. A study was conducted to investigate these findings further by evaluating the effects of altering brain 5-HT levels on the daily fluctuation of plasma corticosterone and on the response of the pituitary-adrenal system to a stressful or noxious stimulus in the rat. In a number of experiments brain 5-HT synthesis was inhibited with parachlorophenylalanine. In other tests it was tried to raise the level of brain 5-HT with precursors.

    Congenital adrenal hyperplasia (CAH) is a group of autosomal recessive disorders characterized by enzyme defects in adrenal steroidogenic pathways. CAH due to 21-hydroxylase deficiency accounts for 95 % of cases. This case was diagnosed to have simple virilizing type of CAH and started on dexamethasone, and underwent genitoplasty and clitoroplasty at 25 years of age, then was married 3 years after surgery and conceived spontaneously 2 years after marriage, to deliver a healthy male baby. Thus, proper diagnosis and treatment with steroids and genitoplasty can give females with CAH a normal sexual, normal menstrual, and reproductive function.

    While testicular adrenal rest tumor is generally a rare intratesticular tumor, it is frequent in patients with congenital adrenal hyperplasia. The tumors are diagnosed and followed up by ultrasound examination because these tumors are non-palpable and symptomless in most cases and always benign. Ultrasound imaging features change depending on how congenital adrenal hyperplasia is controlled. We herein report three cases of testicular adrenal rest tumors with different usual and unusual imaging findings and follow-up imaging. Patient 1 was a 14-year-old boy who presented with poor compliance to medication. Patient 2 and 3 were a 10-year-old and 13-year-old boy who presented with precocious puberty and short stature, respectively. Ultrasound examinations demonstrated oval hypoechoic masses and irregular speculated hyperechoic masses in the testes and different serial imaging findings.

    International Nuclear Information System (INIS)

    The aim of this study was to increase awareness of, and to show the variable clinical and radiological features of, subchondral insufficiency fractures of the femoral head. The clinical and radiological findings in 7 patients with subchondral insufficiency fractures of the femoral head were reviewed retrospectively. The diagnosis was confirmed histologically in 4 patients. Radiographs were performed in all patients, MRI in 5 and scintigraphy in 4 patients. Radiographs showed varying degrees of femoral head collapse in 4 patients. In the remaining 3 patients radiographs showed a normal femoral head, regional osteoporosis and focal sclerosis, respectively. Magnetic resonance imaging showed a low-signal band on T1- and T2-weighted images in the subchondral bone adjacent or parallel to the articular surface associated with bone marrow oedema. Scintigraphy showed increased uptake in the femoral head. Insufficiency fractures of the femoral head are easily overlooked or confused with avascular necrosis and, when there is significant joint destruction, osteoarthritis. Unsuspected insufficiency fracture of the femoral head can lead to significant and rapid loss of bone stock in osteoporotic patients waiting for arthroplasty for osteoarthritis. Increased awareness of this condition will hopefully lead to earlier diagnosis and a successful outcome of conservative treatment. (orig.)

    2008-01-01

    Full Text Available INTRODUCTION Neurofibromatosis type 1 is one of the most common genetically transmitted diseases with a high index of spontaneous mutations and extremely varied and unpredictable clinical manifestations. It is diagnosed by the existence of certain clinical criteria. The presence of numerous localised cutaneous neurofibromas or a plexiform neurofibroma is virtually pathognomonic of neurofibromatosis type 1. The incidence of pheochromocytoma in neurofibromatosis type 1 is 0.1-5.7%. CASE OUTLINE A 56-year old female patient was admitted for further evaluation of incidental adrenal tumour previously diagnosed on computerized tomography (CT. She had previously unrecognized neurofibromatosis type 1 and a clinical picture which could remind of pheochromocytoma. None of the catecholamine samples in 24 hr urine indicated functionally active pheochromocytoma. Chromogranin A was moderately increased. Decision for operation was made after performing the image techniques. Adrenal incidentaloma had features of pheochromocytoma on abdominal magnetic resonance imaging (MRI, with positive 131I-MIBG (iodine 131-labelled metaiodobenzylguanidine scintigraphy. After being treated with phenoxybenzamine and propranolol, she was operated on. The pathohistological finding showed the case of left adrenal pheochromocytoma. CONCLUSION Detailed diagnostic procedure for pheochromocytoma should be performed with patients having neurofibromatosis type 1 and adrenal incidentaloma. Pheochromocytomas are rare tumours with fatal outcome if not duly recognized and cured.

    We encountered a patient who presented extreme weight loss and received an eating disorder diagnosis that was later identified as adrenal Cushing's syndrome. A 32-year-old woman with a 2-year history of an eating disorder was admitted to our psychiatric ward due to dehydration, malnutrition and low weight. Her height and body weight were 152.1 cm and 29.8 kg, respectively (body mass index: 12.8). Her other symptoms included a depressed mood, decreased interest, retardation and suicidal ideation. Standard medical cares were prescribed to treat the depressive symptoms and eating disorder, but the depressive episode and low body weight of the patient persisted. Computed tomography of the abdomen revealed an unexpected left adrenal gland tumor. Cushing's syndrome was diagnosed based on several endocrinological examinations. After an enucleation of the left adrenal gland tumor, the patient began eating, and her body weight increased gradually. Her body weight increased to 42.0-47.0 kg (body mass index: 18.2-20.3). Her mental and physical conditions had stabilized. This case suggests that adrenal Cushing's syndrome may resemble eating disorders.

    Congenital X-linked adrenal hypoplasia (AHC) is a rare disease characterized by primary adrenal insufficiency before adolescence and by hypogonadotropic hypogonadism (HHG) during adolescence. In this paper, we present a Chinese family with AHC. Two brothers, misdiagnosed with adrenal insufficiency of unknown etiology at the age of 9, were correctly diagnosed with AHC when delayed puberty, HHG, and testicular defects were observed. We investigated the clinical features and identified the dosage-sensitive sex reversal AHC critical region of the X chromosome gene 1 (DAX-1) mutation in this kindred. Direct sequencing of the DAX-1 gene revealed that the two siblings have a novel mutation (1268delA) of which their mother is a heterozygous carrier. This mutation causes a frameshift and a premature stop codon at position 436, encoding a truncated protein. It is important to increase knowledge of the mutational spectrum in genes related to this disease, linking phenotype to genotype. PMID:26537215

  16. Computed tomography of the adrenals in patients with tuberculosis

    International Nuclear Information System (INIS)

    We evaluated the adrenals of individuals without tuberculosis (group 1 - G1) and with tuberculosis (group 2 - G2) using computed tomography. The antero-posterior length, the thickness, and the longitudinal length of the adrenals were compared in G1 and G2. The duration of the disease, the occurrence of morphologic abnormalities in G2, the distribution according to sex, age and skin color were also studied. There was difference in the antero-posterior length and thickness of right adrenal between G1 and G2. A higher prevalence of white skin male individuals was observed in G2. There was no association between duration of the disease and the occurrence of morphologic abnormalities in G2. A higher occurrence of adrenal enlargement was observed in G2. The main computed tomography findings in patients with tuberculosis were enlargement of the adrenal without calcification, enlargement of the adrenal with punctiform calcifications, and residual calcification of the adrenal.

    Full Text Available Synchronous bilateral renal cell carcinoma occurs in 1.4 % of cases. The probability of bilateral adrenal metastases from renal cell carcinoma is less than 0.5 %. The clinical observation presents a case of synchronous bilateral renal cell carcinoma and simultaneous metastatic involvement of both adrenal glands. A 55‑year-old male patient was adm tted with the signs of hematuria and anemia to the Unit of Urology, Clinic of General Surgery, Siberian State Medical University. He was found to have synchronous bilateral renal cell carcinoma and simultaneous bilateral adrenal involvement. Sequential surgical treatment – radical nephrectomy (with adrenal gland removal on the right side and, after 3 months, adrenalectomy and kidney resection on the left side were performed. All the organs removed displayed tumors that proved to be renal cell carcinomas (a clear cell variant. There were lymph node metastases in the right-sided renal portal. Postoperatively, the investigators performed hormone replacement therapy for adrenal insufficiency, an immunotherapy cycle, three cycles of targeted therapy withsorafenib and sunitinib (at an interval of 0.5–2 years, and insulin therapy for new-onset diabetes mellitus. The duration of a follow-up was 6.2 years. When describing the case, the patient was alive and showed a generalized tumorous process with extensive tumor involvement of the solitary kidney. Sunitinib therapy was used.

  3. Differentiation of adrenal tumors in patients with hepatocellular carcinoma: Adrenal adenoma versus metastasis

    International Nuclear Information System (INIS)

    Objective: To investigate whether computed tomography (CT) attenuation test for differential diagnosis of adrenal nodule is applicable in patients with hepatocellular carcinoma (HCC) which shows similar image characteristics to adrenal adenoma. Materials and methods: This retrospective study was approved by our institutional review board, and the requirement for informed consent from study patients was waived. Searching picture archiving and communication system, we identified 3678 patients with HCC who underwent upper abdominal unenhanced CT scans between April 2002 and March 2010, and 114 adrenal nodules (39 adenomas and 75 metastases) were included for analysis. Ten nodules were confirmed pathologically while 104 had imaging diagnosis (enlarged or emerged during the study period). Size, CT number, and the internal characteristics of the lesions were recorded. Results: Mean CT numbers of adrenal adenomas were significantly lower than those of metastases (P < 0.0001, t-test) on unenhanced CT. Thresholds of 17 and 33 Hounsfield units (HU) provided the following sensitivity, specificity, and accuracy: 46.2%, 100%, and 81.6% at 17 HU, and 94.9%, 89.3%, and 91.2% at 33 HU, respectively. The area under receiver operating characteristic curve for the CT number test was 0.96. Metastases were significantly larger than adrenal adenoma (P = 0.009, t-test). However, the accuracy of testing using mass size was 64.0% at most. All adenomas and metastases were depicted as homogeneous masses with the exception of two metastases that presented as heterogeneous masses (necrotic or lipomatous). Conclusion: Adrenal adenomas can be differentiated from HCC metastases using CT number on unenhanced CT

  8. Inflammatory manifestations of experimental lymphatic insufficiency.

    Directory of Open Access Journals (Sweden)

    Raymond Tabibiazar

    2006-07-01

    Full Text Available BACKGROUND: Sustained lymph stagnation engenders a pathological response that is complex and not well characterized. Tissue inflammation in lymphedema may reflect either an active or passive consequence of impaired immune traffic. METHODS AND FINDINGS: We studied an experimental model of acute post-surgical lymphedema in the tails of female hairless, immunocompetent SKH-1 mice. We performed in vivo imaging of impaired immune traffic in experimental, murine acquired lymphatic insufficiency. We demonstrated impaired mobilization of immunocompetent cells from the lymphedematous region. These findings correlated with histopathological alterations and large-scale transcriptional profiling results. We found intense inflammatory changes in the dermis and the subdermis. The molecular pattern in the RNA extracted from the whole tissue was dominated by the upregulation of genes related to acute inflammation, immune response, complement activation, wound healing, fibrosis, and oxidative stress response. CONCLUSIONS: We have characterized a mouse model of acute, acquired lymphedema using in vivo functional imaging and histopathological correlation. The model closely simulates the volume response, histopathology, and lymphoscintigraphic characteristics of human acquired lymphedema, and the response is accompanied by an increase in the number and size of microlymphatic structures in the lymphedematous cutaneous tissues. Molecular characterization through clustering of genes with known functions provides insights into processes and signaling pathways that compose the acute tissue response to lymph stagnation. Further study of genes identified through this effort will continue to elucidate the molecular mechanisms and lead to potential therapeutic strategies for lymphatic vascular insufficiency.

    2010-12-01

    Chronic cerebrospinal venous insufficiency (CCSVI) is a syndrome characterized by stenosies of the internal jugular and/or azygous veins (IJVs-AZ) with opening of collaterals and insufficient drainage proved by reduced cerebral blood flow and increased mean transit time in cerebral MRI perfusional study. The present review is aimed to give a comprehensive overview of the actual status of the art of the diagnosis and treatment of this condition. As far as the origin of venous narrowing is concerned, phlebographic studies of the IJVs and AZ systems demonstrated that venous stenoses were likely to be truncular venous malformations; mostly, they are intraluminal defects such as malformed valve, septa webs. CCSVI condition has been found to be strongly associated with multiple sclerosis (MS), a disabling neurodegenerative and demyelinating disease considered autoimmune in nature. In several epidemiological observations performed at different latitudes on patients with different genetic backgrounds, the prevalence of CCSVI in MS ranges from 56% to 100%. To the contrary, by using venous MR and/or different Doppler protocols, CCSVI was not detected with the same prevalence. Two pilot studies demonstrated the safety and feasibility in Day Surgery of the endovascular treatment of CCSVI by means of balloon angioplasty (PTA). It determines a significant reduction of postoperative venous pressure. Restenosis rate was found out elevated in the IJVs, but negligible in the AZ. However, PTA seems to positively influence clinical and QoL parameters of the associated MS and warrants further randomized control trials.

    2016-01-01

    BACKGROUND Uterine papillary serous carcinoma (UPSC) is a highly malignant form of endometrial cancer with a high propensity for metastases and recurrences even when there is minimal or no myometrial invasion. It usually metastasizes to the pelvis, retroperitoneal lymph nodes, upper abdomen, and peritoneum. However, adrenal metastases from UPSC is extremely rare. Here, we present a case of UPSC with adrenal metastasis that occurred 6 years after the initial diagnosis. CASE REPORT A 60-year-old woman previously diagnosed with uterine papillary serous carcinoma at an outside facility presented in September of 2006 with postmenopausal bleeding. She underwent comprehensive surgical staging with FIGO (International Federation of Gynecology and Obstetrics) stage 2. Post-operatively, the patient was treated with radiation and chemotherapy. The treatment was completed in April of 2007. The patient had no evidence of disease until July 2009 when she was found to have a mass highly suspicious for malignancy. Subsequently, she underwent right upper lobectomy. The morphology of the carcinoma was consistent with UPSC. She refused chemotherapy due to a previous history of chemotherapy-induced neuropathy. The patient was followed up with regular computed tomography (CT) scans. In October 2012 a new right adrenal nodule was seen on CT, which showed intense metabolic uptake on positron emission tomography (PET)/CT scan. The patient underwent right adrenalectomy. Pathology of the surgical specimen was consistent with UPSC. CONCLUSIONS UPSC is an aggressive variant of endometrial cancer associated with high recurrence rate and poor prognoses. Long-term follow-up is needed because there is a possibility of late metastases, as in this case. PMID:27117594

    The method of transcranial electrostimulation (TCES) has been used for treatment of 68 patients with chronic cerebral vascular insufficiency, stages I and II. A treatment course included 7 daily procedures. The influence of TCES was evaluated clinically, by EEG, transcranial ultrasonic Doppler study and hemodynamic indices in arteries and veins as well as by expression of trait and state anxiety. All the parameters were compared to those of the control group which was treated using conventional methods. TCES resulted in normalization of cerebral vascular reactivity, a decrease of venous circulation disturbances, positive influence on cerebral blood flow and EEG parameters, that corresponded to global improvement of the patients' state, regress of cephalgic syndrome and reduction of trait and state anxiety. The method is simple and safety and can be recommended for wide application including outpatient setting.

Duplex ultrasonography incorporates both gray scale images to delineate anatomy and color-Doppler imaging that visualizes the flow of blood in a structure. Assessment of great saphenous vein requires definition of the anatomy, augmentation of flow, evaluation for both superficial and deep vein thrombosis, and determining the presence of reflux. Currently, evolution in the treatment of reflux also relies on ultrasound for the treatment of the disease. Understanding the utilization of the ultrasound for the diagnosis and treatment of greater saphenous vein reflux is important for practitioners treating reflux disease.

  17. Pitfalls of adrenal imaging with chemical shift MRI

    International Nuclear Information System (INIS)

    Chemical shift (CS) MRI of the adrenal glands exploits the different precessional frequencies of fat and water protons to differentiate the intracytoplasmic lipid-containing adrenal adenoma from other adrenal lesions. The purpose of this review is to illustrate both technical and interpretive pitfalls of adrenal imaging with CS MRI and emphasize the importance of adherence to strict technical specifications and errors that may occur when other imaging features and clinical factors are not incorporated into the diagnosis. When performed properly, the specificity of CS MRI for the diagnosis of adrenal adenoma is over 90%. Sampling the in-phase and opposed-phase echoes in the correct order and during the same breath-hold are essential requirements, and using the first echo pair is preferred, if possible. CS MRI characterizes more adrenal adenomas then unenhanced CT but may be non-diagnostic in a proportion of lipid-poor adenomas; CT washout studies may be able to diagnose these lipid-poor adenomas. Other primary and secondary adrenal tumours and supra-renal disease entities may contain lipid or gross fat and mimic adenoma or myelolipoma. Heterogeneity within an adrenal lesion that contains intracytoplasmic lipid could be due to myelolipoma, lipomatous metaplasia of adenoma, or collision tumour. Correlation with previous imaging, other imaging features, clinical history, and laboratory investigations can minimize interpretive errors

    Purpose: To evaluate the incidence and cause of hypertension prospectively during adrenal radiofrequency ablation (RFA). Methods: For this study, approved by our institutional review board, written informed consent was obtained from all patients. Patients who received RFA for adrenal tumors (adrenal ablation) and other abdominal tumors (nonadrenal ablation) were included in this prospective study. Blood pressure was monitored during RFA. Serum adrenal hormone levels including epinephrine, norepinephrine, dopamine, and cortisol levels were measured before and during RFA. The respective incidences of procedural hypertension (systolic blood pressure >200 mmHg) of the two patient groups were compared. Factors correlating with procedural systolic blood pressure were evaluated by regression analysis.ResultsNine patients underwent adrenal RFA and another 9 patients liver (n = 5) and renal (n = 4) RFA. Asymptomatic procedural hypertension that returned to the baseline by injecting calcium blocker was found in 7 (38.9%) of 18 patients. The incidence of procedural hypertension was significantly higher in the adrenal ablation group (66.7%, 6/9) than in the nonadrenal ablation group (11.1%, 1/9, P < 0.0498). Procedural systolic blood pressure was significantly correlated with serum epinephrine (R{sup 2} = 0.68, P < 0.0001) and norepinephrine (R{sup 2} = 0.72, P < 0.0001) levels during RFA. The other adrenal hormones did not show correlation with procedural systolic blood pressure. Conclusion: Hypertension occurs frequently during adrenal RFA because of the release of catecholamine.

    Objective To explore expression of endogenous ouabain(EO) in multiple adrenal tumors.Methods Thirty-one cases of adrenal tumors and 6 cases of healthy adrenal tissues were selected. The expression of EO in the adrenal tiss ue was detected with immunohistochemical streptavidin peroxadase conjugated(SP) method.Results Most of EO positive products were localized in cy toplasm of the zona reticularis of human adrenal cortex, and positive products s howed to be fine granular. There was no positive signal in the medulla. EO showe d on diffused positive in patients with pheochromocytoma accompanied high blood pressure[SBP:(165.22±7.61) mmHg, DBP:(105.52±4.26) mmHg], but there were neg ative in ones with normative blood pressure[SBP:(118.52±4.58) mmHg, DBP:(83±3.60) m mHg]. The expression of EO was positive in all adrenocortical hyperplasic, aden oma an d carcinoma, no matter its high or normative blood pressure. The degree of expre ssion of EO in adrenal tissues was related to the level of BP.Conclusion Expression of endogenous ouabain(EO) in health y adrenal tissue and adrenal tumors was a valuable morphological and pathophysio logical clue for the research on ouabain.

    Full Text Available We report a case of synchronous bilateral adrenal metastasis of renal cell carcinoma. The contralateral metastatic adrenal mass was treated by the laparoscopic transperitoneal approach. The renal mass and its huge ipsilateral metastatic adrenal gland were removed en bloc with open procedure. A 54-year-old man presented to our clinic with left-sid renal cell carcinoma synchronously bilateral adrenal metastases. The primary tumor was localized in the upper-mid pole of the kidney. The diagnosis was established preoperatively by computed tomography. The size of the contralateral adrenal mass was 65 x 45 mm, but the ipsilateral metastatic adrenal mass was huge (140 x 65 mm. After all analysis and other scannings for any metastasis, a contralateral lapararoscopic transperitoneal adrenalectomy and a left open nephroadrenalectomy were performed simultaneously. Synchronous bilateral adrenal metastases from primary renal cell carcinoma without another metastasis is very rare. The optimal surgical procedure should be selected according to the metastatic adrenal masses size and the patient%u2019s status.

    Laparoscopic adrenalectomy is considered to be the standard of care for the surgical excision of adrenal masses. The transperitoneal laparoscopic and retroperitoneoscopic approaches are described. Both are safe and as effective as open adrenalectomy, with the added benefit of the minimally invasive approach. It can be utilized for patients requiring surgery for a phaeochromocytoma, adrenal adenoma, adrenal adenocarcinoma, Cushing's syndrome, neuroblastoma, and an incidentaloma. Relative contraindications include previous surgery of the liver or kidney, large tumours (>8-10 cm in diameter) or coagulation disorders. Although the transperitoneal route is used more widely, the retroperitoneal approach provides direct access to the adrenal gland and easy visualization of the adrenal vein. It avoids also colonic mobilization, minimizes the risk of injury to hollow viscera, and the potential risk of adhesion formation. However, the reversed orientation of the kidney and hilum, combined with a significantly smaller working space, may make this approach difficult to master.

Adrenal vein sampling (AVS is a procedure entailing the measurement of aldosterone from both adrenal veins, to diagnose an adrenal source of excess aldosterone secretion. Because unilateral adrenal etiologies of primary aldosteronism may be surgically resected, identifying these sources by venous sampling is critical. Technical aspects of the procedure are reviewed, with emphasis on strategies to avoid common difficulties during AVS. Keywords: primary aldosteronism, hypertension, venous sampling, adrenal adenoma

    Heart failure(HF), the number one cause of death in the western world, is caused by the insufficient performance of the heart leading to tissue underperfusion in response to an injury or insult. It comprises complex interactions between important neurohormonal mechanisms that try but ultimately fail to sustain cardiac output. The most prominent such mechanism is the sympathetic(adrenergic) nervous system(SNS), whose activity and outflow are greatly elevated in HF. SNS hyperactivity confers significant toxicity to the failing heart and markedly increases HF morbidity and mortality via excessive activation of adrenergic receptors, which are G protein-coupled receptors. Thus, ligand binding induces their coupling to heterotrimeric G proteins that transduce intracellular signals. G protein signaling is turned-off by the agonist-bound receptor phosphorylation courtesy of G protein-coupled receptor kinases(GRKs), followed by βarrestin binding, which prevents the GRK-phosphorylated receptor from further interaction with the G proteins and simultaneously leads it inside the cell(receptor sequestration). Recent evidence indicates that adrenal GRK2 and βarrestins can regulate adrenal catecholamine secretion, thereby modulating SNS activity in HF. The present review gives an account of all these studies on adrenal GRKs and βarrestins in HF and discusses the exciting new therapeutic possibilities for chronic HF offered by targeting these proteins pharmacologically.

    Contrast-enhanced ultrasonography is useful in differentiating adrenal gland adenomas from nonadenomatous lesions in human patients. The purposes of this study were to evaluate the feasibility and to describe contrast-enhanced ultrasonography of the normal canine adrenal gland. Six healthy female Beagles were injected with an intravenous bolus of a lipid-shelled contrast agent (SonoVue(®) ). The aorta enhanced immediately followed by the renal artery and then the adrenal gland. Adrenal gland enhancement was uniform, centrifugal, and rapid from the medulla to the cortex. When maximum enhancement was reached, a gradual homogeneous decrease in echogenicity of the adrenal gland began and simultaneously enhancement of the phrenicoabdominal vessels was observed. While enhancement kept decreasing in the adrenal parenchyma, the renal vein, caudal vena cava, and phrenicoabdominal vein were characterized by persistent enhancement until the end of the study. A second contrast enhancement was observed, corresponding to the refilling time. Objective measurements were performed storing the images for off-line image analysis using Image J (ImageJ(©) ). The shape of the time-intensity curve reflecting adrenal perfusion was similar in all dogs. Ratios of the values of the cortex and the medulla to the values of the renal artery were characterized by significant differences from initial upslope to the peak allowing differentiation between the cortex and the medulla for both adrenal glands only in this time period. Contrast-enhanced ultrasonography of the adrenal glands is feasible in dogs and the optimal time for adrenal imaging is between 5 and 90 s after injection. PMID:21521396

    Background Convergence insufficiency is a common eye muscle co-ordination problem in which the eyes have a strong tendency to drift outward (exophoria) when reading or doing close work. Symptoms may include eye strain, headaches, double vision, print moving on the page, frequent loss of place when reading, inability to concentrate, and short attention span. Objectives To systematically assess and synthesize evidence from randomized controlled trials (RCTs) on the effectiveness of non-surgical interventions for convergence insufficiency. Search strategy We searched The Cochrane Library, MEDLINE, EMBASE, Science Citation Index, the metaRegister of Controlled Trials (mRCT) (www.controlled-trials.com) and ClinicalTrials.gov (www.clinicaltrials.gov) on 7 October 2010. We manually searched reference lists and optometric journals. Selection criteria We included RCTs examining any form of non-surgical intervention against placebo, no treatment, sham treatment, or each other. Data collection and analysis Two authors independently assessed eligibility, risk of bias, and extracted data. We performed meta-analyses when appropriate. Main results We included six trials (three in children, three in adults) with a total of 475 participants. We graded four trials at low risk of bias. Evidence from one trial (graded at low risk of bias) suggests that base-in prism reading glasses was no more effective than placebo reading glasses in improving clinical signs or symptoms in children. Evidence from one trial (graded at high risk of bias) suggests that base-in prism glasses using a progressive addition lens design was more effective than progressive addition lens alone in decreasing symptoms in adults. At three weeks of therapy, the mean difference in Convergence Insufficiency Symptoms Survey (CISS) score was −10.24 points (95% confidence interval (CI) −15.45 to −5.03). Evidence from two trials (graded at low risk of bias) suggests that outpatient (or office-based as used in the

  12. Usefulness of F-18 FDG PET/CT in Adrenal Incidentaloma: Differential Diagnosis of Adrenal Metastasis in Oncologic Patients

    International Nuclear Information System (INIS)

    We have evaluated characteristics of adrenal masses incidentally observed in nonenhanced F-18 FDG PET/CT of the oncologic patients and the diagnostic ability of F-18 FDG PET/CT to differentiate malignant from benign adrenal masses. Between Mar 2005 and Aug 2008, 75 oncologic patients (46 men, 29 women; mean age, 60.8±10.2 years; range, 35-87 years) with 89 adrenal masses incidentally found in PET/CT were enrolled in this study. For quantitative analysis, size (cm), Hounsfield unit (HU), maximum standardized uptake value (SUVmax), SUVratio of all 89 adrenal masses were measured. SUVmax of the adrenal mass divided by SUVliver, which is SUVmax of the segment 8, was defined as SUVratio. The final diagnosis of adrenal masses was based on pathologic confirmation, radiologic evaluation (HU<0 : benign), and clinical decision. Size, HU, SUVmax, and SUVratio were all significantly different between benign and malignant adrenal masses.(P < 0.05) And, SUVratio was the most accurate parameter. A cut-off value of 1.0 for SUVratio provided 90.9% sensitivity and 75.6% specificity. In small adrenal masses (1.5 cm or less), only SUVratio had statistically significant difference between benign and malignant adrenal masses. Similarly a cut-off value of 1.0 for SUVratio provided 80.0% sensitivity and 86.4% specificity. F-18 FDG PET/CT can offer more accurate information with quantitative analysis in differentiating malignant from benign adrenal masses incidentally observed in oncologic patients, compared to nonenhanced CT

    Sacral insufficiency fractures (SIFs) are a common cause of back pain in the elderly. SIFs mimic the symptoms of lumbar spine pathology and so are commonly missed or underdiagnosed. Here we present four cases of missed SIFs that were subsequently identified and treated. One patient was treated as mechanical lower back ache, another patient underwent root block and two patients underwent surgery for lumbar canal stenosis. None experienced relief of their symptoms after these procedures. Retrospective analysis of X-ray and magnetic resonance imaging data revealed SIFs that were confirmed by computed tomography scans. All four patients were treated for underlying osteoporosis. Two patients who underwent surgery were treated conservatively and other two were treated by sacroplasty involving injection of cement into the fracture. Sacroplasty produced immediate pain relief and early mobilization compared to the conservative group. SIFs should always be considered in the differential diagnosis of an elderly patient presenting with low back symptoms. Sacroplasty can be considered for immediate pain relief and rapid mobilization.

  14. Premature ovarian insufficiency: Pathogenesis and management

    Full Text Available The term premature ovarian insufficiency (POI describes a continuum of declining ovarian function in a young woman, resulting in an earlier than average menopause. It is a term that reflects the variable nature of the condition and is substantially less emotive than the formerly used "premature ovarian failure" which signaled a single event in time. Contrary to the decline in the age of menarche seen over the last 3-4 decades there has been no similar change in the age of menopause. In developed nations, the average age for cessation of menstrual cycles is 50-52 years. The age is younger among women from developing nations. Much has been written about POI despite a lack of good data on the incidence of this condition. It is believed that 1% of women under the age of 40 years and 0.1% under the age of 30 years will develop POI. Research is increasingly providing information about the pathogenesis and treatments are being developed to better preserve ovarian function during cancer treatment and to improve fertility options. This narrative review summarizes the current literature to provide an approach to best practice management of POI.

    Purpose. To determine rate of convergence insufficiency (CI) and accommodative insufficiency (AI) and assess the relation between CI, AI, visual symptoms, and astigmatism in school-age children. Methods. 3rd–8th-grade students completed the Convergence Insufficiency Symptom Survey (CISS) and binocular vision testing with correction if prescribed. Students were categorized by astigmatism magnitude (no/low: AI, and presence of symptoms. Analyses determine rate of clinical CI and AI and symptomatic CI and AI and assessed the relation between CI, AI, visual symptoms, and astigmatism. Results. In the sample of 484 students (11.67 ± 1.81 years of age), rate of symptomatic CI was 6.2% and symptomatic AI 18.2%. AI was more common in students with CI than without CI. Students with AI only (p = 0.02) and with CI and AI (p = 0.001) had higher symptom scores than students with neither CI nor AI. Moderate and high astigmats were not at increased risk for CI or AI. Conclusions. With-the-rule astigmats are not at increased risk for CI or AI. High comorbidity rates of CI and AI and higher symptoms scores with AI suggest that research is needed to determine symptomatology specific to CI. PMID:27525112

  16. Characterization of novel StAR (steroidogenic acute regulatory protein mutations causing non-classic lipoid adrenal hyperplasia.

    Directory of Open Access Journals (Sweden)

    Christa E Flück

    Full Text Available CONTEXT: Steroidogenic acute regulatory protein (StAR is crucial for transport of cholesterol to mitochondria where biosynthesis of steroids is initiated. Loss of StAR function causes lipoid congenital adrenal hyperplasia (LCAH. OBJECTIVE: StAR gene mutations causing partial loss of function manifest atypical and may be mistaken as familial glucocorticoid deficiency. Only a few mutations have been reported. DESIGN: To report clinical, biochemical, genetic, protein structure and functional data on two novel StAR mutations, and to compare them with published literature. SETTING: Collaboration between the University Children's Hospital Bern, Switzerland, and the CIBERER, Hospital Vall d'Hebron, Autonomous University, Barcelona, Spain. PATIENTS: Two subjects of a non-consanguineous Caucasian family were studied. The 46,XX phenotypic normal female was diagnosed with adrenal insufficiency at the age of 10 months, had normal pubertal development and still has no signs of hypergonodatropic hypogonadism at 32 years of age. Her 46,XY brother was born with normal male external genitalia and was diagnosed with adrenal insufficiency at 14 months. Puberty was normal and no signs of hypergonadotropic hypogonadism are present at 29 years of age. RESULTS: StAR gene analysis revealed two novel compound heterozygote mutations T44HfsX3 and G221S. T44HfsX3 is a loss-of-function StAR mutation. G221S retains partial activity (∼30% and is therefore responsible for a milder, non-classic phenotype. G221S is located in the cholesterol binding pocket and seems to alter binding/release of cholesterol. CONCLUSIONS: StAR mutations located in the cholesterol binding pocket (V187M, R188C, R192C, G221D/S seem to cause non-classic lipoid CAH. Accuracy of genotype-phenotype prediction by in vitro testing may vary with the assays employed.

    2015-01-01

    Full Text Available Adrenal incidentalomas are found incidentally during a radiologic examination performed for indications other than an adrenal disease, and 15% of them are bilateral adrenal masses. This study describes a 51-year-old male smoker patient admitted with diabetes mellitus. An abdominal ultrasonography performed due to his anemia revealed bilateral adrenal masses. His chest X-ray showed abnormal 10 cm opacity at the right upper lung, and brain, thorax, and abdomen CT scans showed multiple lesions compatible with lung cancer metastases. The pathological examination of the transthoracic lung biopsy specimen was consistent with lung adenocarcinoma. Findings in this patient indicate that, in middle aged patients with bilateral adrenal mass and a history or finding of any malignancy, the first diagnosis which should be considered is adrenal metastasis, and confirming the diagnosis by adrenal biopsy may be useless. Furthermore, screening all smoking patients by chest X-ray or thoracic CT for lung cancer may not be accepted as a routine procedure, but in smokers admitted to a hospital due to signs and symptoms attributed to a pulmonary disease, at least a chest X-ray should be requested.

  20. Dexamethasone-suppression adrenal scintigraphy in hyperandrogenism: concise communication

    International Nuclear Information System (INIS)

    To assess the contribution of adrenal-derived androgens in women with hirsutism, adrenal scintigrams under dexamethasone suppression (DS) were performed on 35 women with increasing facial or body hair and irregular or absent menses. Based upon the DS regimen chosen (8 mg/d for 2 days or 4 md/d for 7 days before the injection of 6β-[131I]iodomethylnorcholesterol), three imaging patterns were identified. The first was the absence of uptake before 3 days (8-mg DS) or before 5 days (4-mg DS) after injection. This imaging pattern was seen in 17 of the 35 patients studied and was considered normal. The second pattern was bilateral uptake earlier than 3 days (8-mg DS regimen) or 5 days (4-mg DS) after injection. This was seen in 13 of the 35 patients and was interpreted as bilateral early visualization. Adrenal-vein catheterization performed on six patients with this pattern showed increased adrenal-vein testosterone. The third pattern, observed in five patients, was unilateral early visualization, which in four cases investigated to date was the result of an adrenocortical adenoma. This study confirms the adrenal cortex as a source of androgens in women with hirsutism and hyperandrogenism and demonstrates that DS adrenal scintigraphy can be utilized to identify those women in whom adrenal-derived androgens contribute to their hyperandrogenism

  2. Adrenal gland infection by serotype 5 adenovirus requires coagulation factors.

    Directory of Open Access Journals (Sweden)

    Lucile Tran

    Full Text Available Recombinant, replication-deficient serotype 5 adenovirus infects the liver upon in vivo, systemic injection in rodents. This infection requires the binding of factor X to the capsid of this adenovirus. Another organ, the adrenal gland is also infected upon systemic administration of Ad, however, whether this infection is dependent on the cocksackie adenovirus receptor (CAR or depends on the binding of factor X to the viral capsid remained to be determined. In the present work, we have used a pharmacological agent (warfarin as well as recombinant adenoviruses lacking the binding site of Factor X to elucidate this mechanism in mice. We demonstrate that, as observed in the liver, adenovirus infection of the adrenal glands in vivo requires Factor X. Considering that the level of transduction of the adrenal glands is well-below that of the liver and that capsid-modified adenoviruses are unlikely to selectively infect the adrenal glands, we have used single-photon emission computed tomography (SPECT imaging of gene expression to determine whether local virus administration (direct injection in the kidney could increase gene transfer to the adrenal glands. We demonstrate that direct injection of the virus in the kidney increases gene transfer in the adrenal gland but liver transduction remains important. These observations strongly suggest that serotype 5 adenovirus uses a similar mechanism to infect liver and adrenal gland and that selective transgene expression in the latter is more likely to be achieved through transcriptional targeting.

    Full Text Available Abstract Background Most research concerning congenital adrenal hyperplasia (CAH and related conditions caused by primary adrenal insufficiency, such as Addison's or Cushing's disease, has focused on medical aspects rather than on patients' quality of life. Therefore, our objective was to investigate the physical, social and societal functioning of children with CAH and their parents in a Dutch population. Methods The study is descriptive and cross-sectional. Self-designed questionnaires, based on questionnaires developed in the Netherlands for different patient groups, were sent to parents of children with CAH between 0 and 18 years old. Participants were recruited through the Dutch patient group for Adrenal Disease (NVACP and six hospitals in the Netherlands. Three different questionnaires were designed for parents: for children aged 0 - 4, aged 4 - 12 and aged 12 - 18. Additionally, a fourth questionnaire was sent to adolescents with CAH aged 12 - 18. Main outcome measures were experienced burden of the condition, self-management and participation in several areas, such as school and leisure time. Results A total of 106 parents returned the questionnaire, 12 regarding pre-school children (0-4 years, 63 regarding primary school children (4-12 years, and 32 regarding secondary school children (12-18 years, combined response rate 69.7%. Also, 24 adolescents returned the questionnaire. Children and adolescents with CAH appear to be capable of self-management at a young age. Experienced burden of the condition is low, although children experience several health related problems on a daily basis. Children participate well in school and leisure time. Few children carry a crisis card or emergency injection with them. Conclusions Overall, our research shows that, according to their parents, children with CAH experience few negative effects of the condition and that they participate well in several areas such as school and leisure time.

  4. Radioimmunological determination of dehydroepiandrosterone sulfate in premature, mature and deficient born children as a parameter in the determination of the functional condition of the fetal adrenal cortex

    International Nuclear Information System (INIS)

    The starting point of this work was the question of a correlation between serum concentration of dehydroepiandrosterone sulfate (DS) and gestation age. It was shown that after the sixth day of life, a negative correlation existed between the DS concentration in the serum of neonates and their gestation age. With non-stressed neonates DS can be used as a parameter of maturity. Vaginal birth and severe illness of premature, respectively newborn children cause a massive stimulation of DS secretion through the fetal zone of the adrenal cortex. Between the DS concentrations and the prolactin levels no correlation could be proven, so that there can be no discussion of prolactin as an alternative stimulator on the fetal zone of the adrenal cortex. The DS values presented in this work for premature and mature neonates of varying gestation age can be used as reference values by pediatric endocrinologists for the evaluation of a newborn with the suspect diagnosis of an adrenogenital syndrome or an adrenal insufficiency. The DS-radioimmunoassay is a practicable method for newborns because of its simplicity, quickness, and demand for only small amounts of serum and it is sufficiently specific and provides a good statement about the functional condition of the adrenal gland of newborns.

    Full Text Available Testicular adrenal rest tumors (TARTs are considered to be formed from aberrant adrenal tissue that has become hyperplastic because of elevated adrenocorticotropic hormone (ACTH in male patients with congenital adrenal hyperplasia (CAH. A 6-year-old boy presented with testicular enlargement and pubic hair. He was diagnosed with CAH complicated by precocious puberty. However, he was not followed-up. At the age of 17, he visited the outpatient clinic because of testicular enlargement and short stature. His right and left testicles were 10×6 cm and 7.5×4.5 cm, respectively. His height was 155.1 cm (standard deviation score [SDS], -2.90. The diagnosis of CAH due to 21 hydroxylase deficiency was confirmed by mutation analysis of CYP21A2. Histological examination of the testes showed large, polygonal, eosinophilic cells with round nuclei and prominent nucleoli, which were suggestive of TARTs. He was treated with dexamethasone for 3 weeks and tumors regressed. Subsequently, dexamethasone was replaced by prednisolone and 9?#7014;ludrocortisone; thereafter, the reduced testis size has been maintained.

  6. Adrenal pseudomasses due to varices: angiographic-CT-MRI-pathologic correlations

    International Nuclear Information System (INIS)

    Periadrenal and adrenal portosystemic collaterals are a recently reported cause of adrenal pseudotumor on computed tomography (CT). Nine patients with this left adrenal pseudotumor illustrate its typical position and appearance on CT, angiography, CT-angiography, and magnetic resonance imaging (MRI). The anatomic basis for variceal adrenal pseudotumors is the left inferior phrenic vein, which passes immediately anterior to the left adrenal gland and which serves as a collateral pathway from splenic to left renal vein in portal hypertension. Thus, unlike previously described adrenal pseudotumors, these venous collaterals are not anatomically distinguishable from the adrenal gland on CT. Bolus dynamic CT is usually diagnostic, but in equivocal cases, MRI may prove useful

    2013-08-01

    Full Text Available The objective of this review is to analyze the actual scientific controversy on chronic cerebrospinal venous insufficiency (CCSVI and its association with both neurodegenerative disorders and multiple sclerosis (MS. We revised all published studies on prevalence of CCSVI in MS patients, including ultrasound and catheter venography series. Furthermore, we take into consideration other publications dealing with the pathophysiologic consequences of CCSVI in the brain, as well as ecent data characterizing the pathology of the venous wall in course of CCSVI. Finally, safety and pilot data on effectiveness of endovascular CCSVI treatment were further updated. Studies of prevalence show a big variability in prevalence of CCSVI in MS patients assessed by established ultrasonographic criteria. This could be related to high operator dependency of ultrasound. However, 12 studies, by the means of more objective catheter venography, show a prevalence >90% of CCSVI in MS. Global hypo-hypoperfusion of the brain, and reduced cerebral spinal fluid dynamics in MS was shown to be related to CCSVI. Postmortem studies and histology corroborate the 2009 International Union of Phlebology (UIP Consensus decision to insert CCSVI among venous malformations. Finally, safety of balloon angioplasty of the extracranial veins was certainly demonstrated, while prospective data on the potential effectiveness of endovascular treatment of CCSVI support to increase the level of evidence by proceeding with a randomized control trial (RCT. Taking into account the current epidemiological data, including studies on catheter venography, the autoptic findings, and the relationship between CCSVI and both hypo-perfusion and cerebro-spinal fluid flow, we conclude that CCSVI can be definitively inserted among the medical entities. Research is still inconclusive in elucidating the CCSVI role in the pathogenesis of neurological disorders. The controversy between the vascular and the

A growing body of evidence challenges the central role of pathogenic bacteria in mastitis, with disease severity associated with markers of inflammation rather than infection. Inflammation in the mammary gland may be triggered by microbe-associated molecular patterns (MAMPs) as well as danger-associated molecular patterns (DAMPs) binding to pattern recognition receptors such as the toll-like receptors (TLRs) on the surface of mammary epithelial cells and local immune cell populations. Activation of the TLR4 signalling pathway and downstream nuclear factor kappa B (NFkB) is critical to mediating local mammary gland inflammation and systemic immune responses in mouse models of mastitis. However, activation of NFkB also induces epithelial cell apoptosis and reduced milk protein synthesis, suggesting that inflammatory mediators activated during mastitis promote partial involution. Perturbed milk flow, maternal stress and genetic predisposition are significant risk factors for mastitis, and could lead to a heightened TLR4-mediated inflammatory response, resulting in increased susceptibility and severity of mastitis disease in the context of low MAMP abundance. Therefore, heightened host inflammatory signalling may act in concert with pathogenic or commensal bacterial species to cause both the inflammation associated with mastitis and lactation insufficiency. Here, we present an alternate paradigm to the widely held notion that breast inflammation is driven principally by infectious bacterial pathogens, and suggest there may be other therapeutic strategies, apart from the currently utilised antimicrobial agents, that could be employed to prevent and treat mastitis in women.

    Three cases of adrenal cystic lymphangioma are reported. In 1 patient the lesion was complicated by intracystic haemorrhage. The remaining 2 patients had a hepatic lesion which was treated in the same surgical operation as the adrenal cyst. Ultrasonography and computerized tomography play a major role in the exploration of these cysts. Their unexpected discovery has become more frequent since these methods have multiplied, and this raises therapeutic problems. The nature of adrenal cysts is determined at histology. In asymptomatic cysts percutaneous needle aspiration can only have an indicative value. PMID:8493206

    Acute appendicitis represents one of the most frequent abdominal emergencies encountered in everyday surgical practice. Local infectious complications are not unusual and retroperitoneal abscesses after acute retrocaecal appendicitis have been previously described. The authors present the case of a 22-years-young female patient, admitted for a right iliac fossa abscess, secondary to gangrenous appendicitis. A right adrenal mass 35/40 mm was revealed during preoperative ultrasound evaluation, which evolved in an adrenal abscess that spontaneously drained 10 days after appendectomy and retrocecal drainage. Adrenal abscesses are exceptionally rare, with only a few cases being reported in the literature, but none of these after acute appendicitis.

    Tumors of the adrenal glands are among the most frequent tumors in cattle; however, few studies have been conducted to describe their characteristics. The aim of this study was to classify 41 bovine adrenal neoplasms from 40 animals based on macroscopic and histologic examination, including....... An immunohistochemistry panel consisting of antibodies against melan A, synaptophysin, and CNPase was considered most useful to classify bovine adrenal tumors. However, the distinction between benign and malignant adrenocortical tumors was based on histologic features as in human medicine....

    Adrenal hypoplasia congenita (AHC) is caused by mutations in the NR0B1 gene on chromosome Xp21.3-p21.2. It manifests as X-linked primary adrenal failure in early infancy or childhood and as hypogonadotropic hypogonadism (HHG) at puberty. Although studies of AHC patients and mutations in the NR0B1 gene have been reported throughout the world, there has previously been only one other case report from Korea. We encountered a 23-year old Korean male with delayed-onset AHC/HHG who had been previously diagnosed with adrenal insufficiency of unknown aetiology at age 13 years. Delayed puberty and incomplete HHG were observed. Direct sequencing of the NR0B1 gene revealed the patient to have a novel insertion mutation (c.959_960insT; Leu321ProfsX68). Although AHC is believed to be rare, it should be considered in a differential diagnosis of patients showing late-onset primary adrenal insufficiency.

    Full Text Available Retroperitoneal location of bronchogenic cysts is extremely rare. Most commonly they are encountered in the posterior mediastinum. Bronchogenic cysts arise from developmental aberrations of the tracheobronchial tree in the early embryologic period. We report a 42-year-old female patient with a retroperitoneal bronchogenic cyst in the left adrenal region. She was admitted to our hospital with epigastric pain and subsequently underwent CT of the abdomen. The examination revealed a mass related to the left adrenal gland. Endocrine tests for adrenal hypersecretion were negative. Because of the uncertain entity, laparoscopic adrenalectomy was performed. Pathological examination revealed a bronchogenic cyst in proximity to an inconspicuous left adrenal gland. Although very rare, bronchogenic cysts should be considered in the differential diagnosis of retroperitoneal cystic lesions and surgical resection pursued for symptom resolution and to establish a definitive histology.

    Of the six GATA transcription factors, GATA-4 and GATA-6 are expressed in the mouse and human adrenal with distinct developmental profiles. GATA-4 is confined to the fetal cortex, i.e. to the less differentiated proliferating cells, while GATA-6 is expressed both in the fetal and adult adrenal. In vitro, GATA-4 regulates inhibin-alpha and steroidogenic factor-1 implicated in normal adrenal function. GATA-6 probably has roles in the development and differentiation of adrenocortical cells, and in the regulation of steroidogenesis. GATA-4 expression is dramatically upregulated and GATA-6 downregulated in gonadotropin dependent mouse adrenocortical tumors. This is accompanied by the appearance of luteinizing hormone receptor (LHR). In vitro, GATA-4 transactivates LHR promoter, and gonadotropins upregulate GATA-4 levels. Human adrenal tumors occasionally express GATA-4, whereas GATA-6 levels are usually lower than normal.

    Plasma corticosterone and ACTH concentrations were determined in neonatal rats 1, 7, 14, and 21 days old, under a variety of experimental conditions, to obtain more information on the postnatal development of the rat hypothalamo-adrenal (HHA) axis. The results indicate that: (1) there is a diminution followed by an increase in responsiveness of the adrenal gland, but the pituitary response to direct hormonal stimulation is unchanged during the first three postnatal weeks; (2) continued stimulation of the adrenal by ACTH or of the central nervous system (CNS) or hypothalamus by corticosterone is necessary during early postnatal development to allow normal maturation of the HHA axis; and (3) feedback inhibition is operative by birth, at least to a moderate degree. Taken together, the studies suggest that both the adrenal and pituitary glands are potentially functional at birth, but that the hypothalamic and CNS mediators of the stress response are not mature until at least the second or third postnatal week.

    Adrenal lymphangiomas, also known as cystic adrenal lymphangiomas, are rare, benign vascular lesions that usually remain asymptomatic throughout life. Although previously adrenal lymphangioma lesions were primarily found at autopsy, they are currently detected during imaging work-up for unrelated causes and are likely to imitate other adrenocortical or adrenal medullary neoplasms. We aimed to retrospectively review all adrenal lymphangioma cases at our hospital and further document their lymphatic origin by immunohistochemical staining. A search of surgical pathology records (1984-2008) was conducted. All hematoxylin and eosin sections were retrieved from archives and reviewed by 2 pathologists in the study. Clinical information was gathered from electronic medical records. Representative paraffin-embedded sections from each case were selected for immunohistochemical analysis using monoclonal antibodies D2-40 and AE1/AE3. A total of 9 adrenal lymphangioma cases were identified (6 women and 3 men). All 9 patients were adults at time of diagnosis with a mean age of 42 years (range, 28-56 years). There were 7 white patients, 1 African American patient, and 1 Asian patient. The average size of an adrenal lymphangioma lesion was 4.9 cm (range, 2.0-13.5 cm). Adrenal lymphangioma was twice more frequently located on the right side (6 right-sided and 3 left-sided). Clinically, 4 (44%) of the 9 lesions presented with abdominal, flank, or back pain. One lymphangioma was found during work-up for labile hypertension. The remaining 4 lesions (44%) were asymptomatic and incidentally found during imaging studies for unrelated causes. Surgical removal was achieved by total adrenalectomy in 8 of the 9 lesions and by partial adrenalectomy in the remaining case. No evidence of recurrence or development of a contralateral lesion was encountered in any of the patients. Histologically, our adrenal lymphangiomas showed a typical multicystic architecture with dilated spaces lined by

    Background Bilateral adrenal masses may have aetiologies like hyperplasia and infiltrative lesions, besides tumours. Hyperplastic and infiltrative lesions may have coexisting hypocortisolism. Bilateral tumours are likely to have hereditary/syndromic associations. The data on clinical profile of bilateral adrenal masses are limited. Aims To analyse clinical, biochemical and radiological features, and management outcomes in patients with bilateral adrenal masses. Methods Retrospective analysis of 70 patients with bilateral adrenal masses presenting to a single tertiary care endocrine centre from western India (2002–2015). Results The most common aetiology was pheochromocytoma (40%), followed by tuberculosis (27.1%), primary adrenal lymphoma (PAL) (10%), metastases (5.7%), non-functioning adenomas (4.3%), primary bilateral macronodular adrenal hyperplasia (4.3%), and others (8.6%). Age at presentation was less in patients with pheochromocytoma (33 years) and tuberculosis (41 years) compared with PAL (48 years) and metastases (61 years) (PAI) (95%). The presenting symptoms for PAL were AI (57%) and abdominal pain (43%), whereas all cases of metastasis had abdominal pain. Mean size of adrenal masses was the largest in lymphoma (5.5cm) followed by pheochromocytoma (4.8cm), metastasis (4cm) and tuberculosis (2.1cm) (P<0.001). Biochemically, most patients with pheochromocytoma (92.8%) had catecholamine excess. Hypocortisolism was common in tuberculosis (100%) and PAL (71.4%) and absent with metastases (P<0.001). Conclusion In evaluation of bilateral adrenal masses, age at presentation, presenting symptoms, lesion size, and biochemical features are helpful in delineating varied underlying aetiologies.

    Objective: To discuss imaging features of the adrenal glands in female pseudohermaphroditism. Methods: 11 cases of female pseudohermaphroditism (8-27 years old) were analyzed retrospectively. Results: In 9 of the 11 patients with female pseudohermaphroditism who did no receive hormone replacement therapy, both internal and external branches of ilateral adrenal glands were found to be thickened, prolonged and twisted, and in 2 of the 9 patients they were found to be macronodularly hyperplasic. In one of the remaining two patients who had received long-term hormone replacement therapy, the adrenal glands were not thickened or twisted, though prolonged; and in the other patient imaging presentation of the adrenal glands was the same as that of those who did not receive hormone replacement therapy, but with co-existence of adrenal myelolipoma. Among the 11 patients agenesis of the uterus and the vagina was found in 4 cases. Conclusion: Female pseudohermaphroditism is a hereditary disease,where hyperplasia of the adrenal glands and agenesis of the uterus and the vagina were secondary. Early detection of these abnormalities by imageology would prove to be helpful in early detection and treatment of the condition.

    Background Airway symptoms in asthma are related to decrease of epinephrine secretion, which may be ascribed to elevated nerve growth factor (NGF) in the organism.The aim of this study was to monitor the neuroendocrine alteration in the adrenal medulla of asthmatic rats.Methods Sixteen rats were randomly divided into two groups (n=8), control group and asthma group, and the asthmatic rats were sensitized and challenged with ovalbumin (OVA).The levels of NGF, epinephrine and norepinephrine in serum were detected by enzyme linked immunosorbent assay (ELISA), the NGF expression in adrenal medulla was detected by immunohistochemistry, and the changes in the ultrastructure of the adrenal medulla was observed by electron microscopy.Results The NGF expression was increased in asthmatic rats compared with control rats.Compared with control rats,the results indicated that the epinephrine level was decreased in asthmatic rats, but no significant difference was found in norepinephrine levels.We found more ganglion cells in the adrenal medulla of asthmatic rats than in control rats, with NGF immunostaining mainly located in these ganglion cells.Electron microscopic images showed the density of chromaffin granula decreased and there was shrunken nucleolemma in the adrenal medullary cells of asthmatic rats.Conclusion The innervation of the adrenal medulla is changed in asthmatic rats, and it may contribute to the epinephrine decrease in asthma.

  10. Chronic ethanol consumption decreases adrenal responsiveness to adrenocorticotropin (ACTH) stimulation

    International Nuclear Information System (INIS)

    Increased alcohol consumption by adolescents and teenagers has heightened awareness of potential endocrine and developmental alterations. The current study was designed to determine whether chronic ethanol intake alters pituitary and adrenal function in the developing rat. One month old male Sprague Dawley rats were administered 6% ethanol in drinking water. After one month of treatment animals were sacrificed and blood, pituitary and adrenal glands collected. Plasma was assayed for ACTH and corticosterone (CS) by radioimmunossay (RIA). Five anterior pituitary glands per group were challenged with 100 μM corticotropin releasing factor (CRF) for 90 min at 37C under 95% air / 5% CO2. Media were analyzed for either ACTH (pituitary) or CS (adrenal) by RIA. Plasma ACTH and CS were unaffected by ethanol consumption. Pituitary response to CRF was not altered by ethanol. The lack of difference in ACTH release was not due to differences in pituitary content of ACTH. However, chronic ethanol consumption did decrease adrenal responsiveness to ACTH stimulation. In vitro corticosterone production was 1.21 ± 0.14 μg/adrenal in controls and 0.70 ± 0.06 μg/adrenal in ethanol consuming rats

  11. Percutaneous interstitial brachytherapy for adrenal metastasis. Technical report

    International Nuclear Information System (INIS)

    We developed and evaluated the feasibility of a brachytherapy technique as a safe and effective treatment for adrenal metastasis. Adapting a paravertebral insertion technique in radiofrequency ablation of adrenal tumors, we developed an interstitial brachytherapy for adrenal metastasis achievable on an outpatient basis. Under local anesthesia and under X-ray CT guidance, brachytherapy applicator needles were percutaneously inserted into the target. A treatment plan was created to eradicate the tumor while preserving normal organs including the spinal cord and kidney. We applied this interstitial brachytherapy technique to two patients: one who developed adrenal metastasis as the third recurrence of uterine cervical cancer after reirradiation, and one who developed metachronous multiple metastases from malignant melanoma. The whole procedure was completed in 2.5 hours. There were no procedure-related or radiation-related early/late complications. 18F-fluorodeoxyglucose positron emission tomography (FDG PET)-CT images at two and three months after treatment showed absence of FDG uptake, and no recurrence of the adrenal tumor was observed for over seven months until expiration, and for six months until the present, respectively. This interventional interstitial brachytherapy procedure may be useful as a safe and eradicative treatment for adrenal metastasis. (author)

  14. Vesicle Pools: Lessons from Adrenal Chromaffin Cells

    Directory of Open Access Journals (Sweden)

    David R Stevens

    2011-02-01

    Full Text Available The adrenal chromaffin cell serves as a model system to study fast Ca2+-dependent exocytosis. Membrane capacitance measurements in combination with Ca2+ uncaging offers a temporal resolution in the millisecond range and reveals that catecholamine release occurs in three distinct phases. Release of a readily releasable (RRP and a slowly releasable (SRP pool are followed by sustained release, due to maturation and release of vesicles which were not release-ready at the start of the stimulus. Trains of depolarizations, a more physiological stimulus, induce release from a small immediately releasable pool of vesicles residing adjacent to calcium channels, as well as from the RRP. The SRP is poorly activated by depolarization. A sequential model, in which non-releasable docked vesicles are primed to a slowly releasable state, and then further mature to the readily releasable state, has been proposed. The docked state, dependent on membrane proximity, requires SNAP-25, synaptotagmin and syntaxin. The ablation or modification of SNAP-25 and syntaxin, components of the SNARE complex, as well as of synaptotagmin, the calcium sensor, and modulators such complexins and Snapin alter the properties and/or magnitudes of different phases of release, and in particular can ablate the RRP. These results indicate that the composition of the SNARE complex and its interaction with modulatory molecules drives priming and provides a molecular basis for different pools of releasable vesicles.

  15. Adrenal lesions encountered in current medical practice − a review of their radiological imaging

    Directory of Open Access Journals (Sweden)

    2013-11-01

    Full Text Available Modern radiological technology has transformed the way that adrenal lesions are currently investigated. The contemporary radiologist has been catapulted to the forefront in the management of adrenal disease. With the increasing use of cross-sectional imaging, adrenal lesions are being serendipitously discovered in radiological studies undertaken for non-adrenal-related conditions – the so-called adrenal ‘incidentaloma’. This review discusses the imaging modalities available for characterising these lesions, highlighting current concepts and controversies in differentiating benign from malignant pathology. The article also provides a brief overview of the spectrum of adrenal pathology commonly encountered in the adult population.

    2010-01-01

    Little information is available on medical imaging of the adrenal glands in horses. We investigated the feasibility of transrectal ultrasonography to characterize the normal equine adrenal gland. Transrectal ultrasonography was performed in 25 healthy horses using a 7.5 MHz linear array probe at a displayed depth of 8 cm. Transrectal ultrasonography of the right adrenal gland was not feasible. For the left adrenal gland, the left kidney, the abdominal aorta, the left renal artery, the left renal vein, and the cranial mesenteric artery were used as landmarks. The size of the left adrenal gland was variable, but it generally appeared as a long, flat structure with a hyperechoic medulla surrounded by a hypoechoic cortex. The most cranial part of the gland could not be delineated appropriately in 11 horses (44%). The mean (+/-SD) thickness of the gland and medulla was 0.66 +/- 0.15cm (n = 25) and 0.28 +/- 0.09 cm (n = 25) near the caudal pole, 0.87 +/- 0.25 cm (n = 14) and 0.40 +/- 0.18 cm (n = 12) near the cranial pole, and 0.89 +/- 0.18 cm (n = 25) and 0.36 +/- 0.13 cm (n = 25) in the middle of the gland, respectively. The mean (+/-SD) length of the entire adrenal gland and of the medulla was 6.22 +/- 0.77 cm (n = 14) and 5.45 +/- 0.71 cm (n = 6), respectively. Transrectal ultrasonography allowed adequate visualization of the left adrenal gland in horses. PMID:20973389

    Dosage-sensitive sex reversal, adrenal hypoplasia congenita (AHC) critical region on the X chromosome, gene 1 (Dax1) is an orphan nuclear receptor essential for development and function of the mammalian adrenal cortex and gonads. DAX1 was cloned as the gene responsible for X-linked AHC, which is characterized by adrenocortical failure necessitating glucocorticoid replacement. Contrary to these human data, young mice with genetic Dax1 knockout (Dax1(-/Y)) exhibit adrenocortical hyperfunction, consistent with the historic description of Dax1 as a transcriptional repressor that inhibits steroidogenic factor 1-dependent steroidogenesis. This paradox of molecular function and two apparently opposite phenotypes associated with Dax1 deficiency in mice and humans is compounded by the recent observations that under certain circumstances, Dax1 can serve as a transcriptional activator of steroidogenic factor 1. The recently revealed role of Dax1 in embryonic stem cell pluripotency, together with the observation that its expression in the adult adrenal is restricted to the subcapsular cortex, where presumptive undifferentiated progenitor cells reside, has led us to reexamine the phenotype of Dax1(-/Y) mice in order to reconcile the conflicting mouse and human data. In this report, we demonstrate that although young Dax1(-/Y) mice have enhanced steroidogenesis and subcapsular adrenocortical proliferation, as these mice age, they exhibit declining adrenal growth, decreasing adrenal steroidogenic capacity, and a reversal of their initial enhanced hormonal sensitivity. Together with a marked adrenal dysplasia in aging mice, these data reveal that both Dax1(-/Y) mice and patients with X-linked AHC exhibit adrenal failure that is consistent with adrenocortical subcapsular progenitor cell depletion and argue for a significant role of Dax1 in maintenance of these cells.

    Autoimmune polyglandular syndrome is a constellation of signs and symptoms of simultaneous insufficiencies of several endocrine glands. Autoimmune polyglandular syndrome type 2 (APS 2) may be diagnosed when the adrenocortical insufficiency is associated with an autoimmune thyroid disease (Hashimoto's thyroiditis or Graves' disease), and/or insulin-dependent diabetes mellitus. Turner syndrome is the most common chromosomal disorder in females, caused by complete or partial X chromosome monosomy. We present the case of a 20-year-old woman with Turner syndrome, in whom APS 2 (Hashimoto's thyroiditis and adrenocortical insufficiency) has been diagnosed after introduction of recombinant human growth hormone (rhGH) therapy. In Turner syndrome, examination of the patient must regularly be conducted in order to diagnose a possible onset of autoimmune diseases; respective treatment must be applied as soon as the diagnosis is established. In particular, therapy of rhGH, used for short stature treatment, may be a trigger factor of adrenal insufficiency. The cortisol level in blood should be assessed before rhGH administration and carefully monitored during the therapy, especially in case of autoimmune thyroid disease coexistence. PMID:26071578

  20. Nonreutilizaton of adrenal chromaffin granule membranes following secretion

    International Nuclear Information System (INIS)

    The intracellular postexocytotic fate of the adrenal chromaffin granule membrane (reutilization vs. nonreutilization) was addressed through two experimental approaches. First, (3H) leucine pulse-chase labeling experiments were conducted in two systems - the isolated retrograde perfused cat adrenal gland and cultured bovine adrenal chromaffin cells to compare chromaffin granule soluble dopamine-B-hydroxylase (DBH) turnover (marker for granule soluble content turnover) to that of membrane-bound DBH (marker for granule membrane turnover). Experiments in cat adrenal glands showed that at all chase periods the granule distribution of radiolabeled DBH was in agreement with the DBH activity distribution (73% membrane-bound/27% soluble) - a result consistent with parallel turnover of soluble and membrane-bound DBH. Experiments in cultured bovine cells showed that labeled soluble and membrane-bound DBH had parallel turnover patterns and at all chase period, the distribution of radiolabeled DBH between the soluble contents and membranes was similar to the DBH activity distribution (50% soluble/50% membrane-bound). The above experiments showed that the soluble contents and membranes turnover in parallel and are consistent with nonreutilization of chromaffin granule membranes following exocytosis. Isolated retrograde perfused bovine adrenal glands were subjected to repetitive acetylcholine stimulation to induce exocytosis and then the dense and less-dense chromaffin granule fractions were isolated. Since both approaches gave results consistent with membrane nonreutilization, the authors conclude that once a chromaffin granule is involved in exocytosis, its membrane is not reutilized for the further synthesis, storage, and secretion of catecholamines

  1. Adrenal hemorrhage after orthotopic liver transplantation: MR appearance

    International Nuclear Information System (INIS)

    The purpose of this paper is to describe the MR imaging findings of right adrenal hemorrhage after orthotopic liver transplantation. Twenty-seven orthotopic liver transplantation patients underwent MR studies of the liver and/or biliary system. Patients were referred to MR examination because of suspected biliary complications (n=22) or for evaluation of mass lesions (n=5). The standard MR protocol included T1-weighted spin-echo (SE) or gradient-recalled echo (GRE) images and T2-weighted turbo SE (TSE) images with fat suppression. In addition, cholangiography pulse sequences and/or contrast-enhanced T1-weighted images were obtained according to specific indications. In 2 patients a right adrenal mass was detected at MR imaging. Three to 4 weeks after transplantation, the lesions were markedly hyperintense on T2-weighted images and showed a hypointense capsule. Follow-up MR examinations revealed a slight decrease in size and a change in morphology. Computed tomography examinations of these 2 patients, obtained 10 weeks after transplantation, showed resolution of the hemorrhage and transformation into a cystic lesion in one case and a complete resolution of the hemorrhage and a normal right adrenal gland in the other case. Adrenal hemorrhage after liver transplantation shows typical MR features and should not be mistaken for an adrenal tumor or a postoperative abscess. (orig.)

    In the years 1976-1980 in 105 patients 124 adrenal scintigrams were obtained, including 50 in patients with primary hyperaldosteronism syndrome, 27 with Cushings syndrome, 8 after bilateral total adrenalectomy, 4 with adrenal virilizing tumours, 6 with phaeochromocytoma, 10 with normal adrenal function. The results of scintigraphy were compared with those of arteriography, phlebography, computer tomography and postoperative findings. The clinical value of scintigraphy was found to be greatest in cases of adrenocortical disease. In cases of phaeochromocytoma isotope angioscintigraphy is a useful method for localizing the tumour since it makes possible demonstration of the vascular bed of the tumour. A close correlation was demonstrated between the results of scintigraphy and those of computer tomography. In the group of 27 patients treated surgically for adrenocortical disease in 87% of cases an agreement was found between the results of scintigraphy and the result of the operation. For different adrenocortical diseases this per cent was: 77% for Cushings syndrome, 91% for primary hyperaldosteronism, 100% for adrenal virilizing tumours. The study showed that adrenal scintigraphy is a very valuable diagnostic method of high clinical usefulness in adrenocortical diseases.

    Indeterminate incidental findings pose a challenge to both the radiologist and the ordering physician as their imaging appearance is potentially harmful but their clinical significance and optimal management is unknown. We seek to determine if it is possible to automate detection of adrenal nodules, an indeterminate incidental finding, on imaging examinations at our institution. Using PRESTO (Pathology-Radiology Enterprise Search tool), a newly developed search engine at our institution that mines dictated radiology reports, we searched for phrases used by attendings to describe incidental adrenal findings. Using these phrases as a guide, we designed a query that can be used with the PRESTO index. The results were refined using a modified version of NegEx to eliminate query terms that have been negated within the report text. In order to validate these findings we used an online random date generator to select two random weeks. We queried our RIS database for all reports created on those dates and manually reviewed each report to check for adrenal incidental findings. This survey produced a ground- truth dataset of reports citing adrenal incidental findings against which to compare query performance. We further reviewed the false positives and negatives identified by our validation study, in an attempt to improve the performance query. This algorithm is an important step towards automating the detection of incidental adrenal nodules on cross sectional imaging at our institution. Subsequently, this query can be combined with electronic medical record data searches to determine the clinical significance of these findings through resultant follow-up.

  4. RETROPERITONEAL LAPAROSCOPIC SURGERY FOR ADRENAL DISEASES (REPORT OF 136 CASES)

    Institute of Scientific and Technical Information of China (English)

    2003-01-01

    Objective: To summarize experiences in 136 cases of retroperitoneal laparoscopic surgery. Methods:From April 1997 to May 2002, retroperitoneal laparoscopic surgery were performed for 136 cases of adrenal dis-eases. There were 63 aldosterone- producing adenoma, 22 adrenalcortical adenoma, 39 nonfunctional adrenal tu-mor, 7 adrenal cyst and 5 phenochromocytoma. Results: Except for one case converts to open surgery, success hasbeen achieved in all cases without major complications. Intraoperative blood loss was 76 + 32ml without blood trans-fusion. Postoperative hospital stay was 6 + 3 days. There were statistical differences among these indices when com-paring to those of open surgery for 126 cases with adrenal diseases( P < 0.05). But operative time was little longer inlaparoscopic group than in group of open surgery(P<0.05) ,whereas it has been changed to similar in those recentcases. Conclusion:Retroperitoneal laparoscopic surgery was less traumatic to the patients, with less postoperative dis-comfort and quicker recovery and should be considered the first choice of therapy for adrenal disorders.

    Full Text Available Introduction. Primary adrenal non-Hodgkin’s lymphoma (NHL is a rare neoplasm with poor prognosis. On the other side, double-hit lymphomas with BCL2 and MYC translocation are characterized by advanced disease stage, extranodal and central nervous system involvements at presentation or disease progression. Case report. We reported a 73-year-old male patient with double-hit primary adrenal lymphoma and preserved adrenal function, showing a favorable clinical course. Computed tomography of abdomen showed a 9 7 cm mass of the left adrenal gland. Laparatomy with left adrenalectomy was done and histological examination revealed diagnosis of a diffuse large B-cell NHL (DLBCL, non-GCB subtype. The patient was treated with 6 cycles of R-CHOP chemotherapy with reduced doses of doxorubicin because of the decreased left verticle ejection fraction. The patient was followed up regularly for 20 months with no evidence of tumor recurrence despite the inherently poor prognostic profile and double-hit phenotype of the disease. Conclusion. R-CHOP chemotherapy in combination with adrenalectomy can be an effective first-line regimen for primary adrenal DLBCL, despite the inherently poor prognostic profile (non-GCB subtype, bulky disease, elevated lactate dehydrogenase and double-hit phenotype of the disease.

    Aldose reductase (AKR1B) proteins are monomeric enzymes, belonging to the aldo-keto reductase (AKR) superfamily. They perform oxidoreduction of carbonyl groups from a wide variety of substrates, such as aliphatic and aromatic aldehydes or ketones. Due to the involvement of human aldose reductases in pathologies, such as diabetic complications and cancer, AKR1B subgroup enzymatic properties have been extensively characterized. However, the issue of AKR1B function in non-pathologic conditions remains poorly resolved. Adrenal activities generated large amount of harmful aldehydes from lipid peroxidation and steroidogenesis, including 4-hydroxynonenal (4-HNE) and isocaproaldehyde (4-methylpentanal), which can both be reduced by AKR1B proteins. More recently, some AKR1B isoforms have been shown to be endowed with prostaglandin F synthase (PGFS) activity, suggesting that, in addition to possible scavenger function, they could instigate paracrine signals. Interestingly, the adrenal gland is one of the major sites for human and murine AKR1B expression, suggesting that their detoxifying/signaling activity could be specifically required for the correct handling of adrenal function. Moreover, chronic effects of ACTH result in a coordinated regulation of genes encoding the steroidogenic enzymes and some AKR1B isoforms. This review presents the molecular mechanisms accounting for the adrenal-specific expression of some AKR1B genes. Using data from recent mouse genetic models, we will try to connect their enzymatic properties and regulation with adrenal functions.

    The prevalence of adrenal incidentaloma (AI) on computed tomography (CT) in the general population has been reported to be as high as 4.2%. However, many of the previous studies in this field utilised a prospective approach with analysis of CT scans performed by one or more radiologists with a specialist interest in adrenal tumours and a specific focus on identifying the presence of an adrenal mass. A typical radiology department, with a focus on the patient\\'s presenting complaint as opposed to the adrenal gland, may not be expected to diagnose as many adrenal incidentalomas as would be identified in a dedicated research protocol. We hypothesised that the number of AI reported in routine clinical practice is significantly lower than the published figures would suggest. We retrospectively reviewed the reports of all CT thorax and abdomen scans performed in our hospital over a 2 year period. 3,099 patients underwent imaging, with 3,705 scans performed. The median age was 63 years (range 18-98). Thirty-seven true AI were diagnosed during the time period studied. Twenty-two were diagnosed by CT abdomen (22\\/2,227) and 12 by CT thorax (12\\/1,478), a prevalence of 0.98 and 0.81% with CT abdomen and thorax, respectively, for AI in routine clinical practice.

  14. Limited significance of asymmetric adrenal visualization on dexamethasone-suppression scintigraphy

    International Nuclear Information System (INIS)

    To access whether a single measurement of the adrenal uptake of 6β-[131I]-iodomethylnorocholesterol (NP-59) on constant dexamethasone suppression would allow discrimination of adenoma from normal and bilateral hyperplasia, the adrenal uptake of 6β-[131I]-iodomethylnorocholesterol (NP-59) was determined in 50 patients with primary aldosteronism (30 adenoma, 20 hyperplasia) and in 13 with hyperandrogenism (six adenoma, seven hyperplasia). Bilateral adrenal NP-59 activity at 5 days was seen in 14 of 36 patients with adenoma whereas marked asymmetric uptake of NP-59 was seen in six of 27 patients with hyperplasia. Thus the level of adrenal NP-59 uptake does not alone serve to distinguish either adenoma from the normal, contralateral adrenal or the adrenal glands in bilateral hyperplasia in all cases. It appears that the pattern of adrenal imaging best serves to separate adrenal adenoma from bilateral hyperplasia

Estradiol was high in two cases at presentation, and after a relapsing tumor in the third one. All had big adrenal tumors (5.9, 6, and 17 cm, and a mixed secretion composed by high estradiol and cortisol. The pathological study argued for malignancy in two cases. But, only one had diffuse metastasis and died 4 years after diagnosis; the others diagnosed one and three years ago are still alive without any metastasis or relapsing.

    2016-05-01

    Although adrenal medullary tumours are rare, they have important clinical implications. They form a heterogeneous group of tumours, ranging from benign, non-secretory, incidental masses to hormonally active tumours presenting acutely, or malignant tumours with disseminated disease and a poor prognosis. Increasingly, benign masses are incidentally detected due to the widespread use of imaging and routine medical check-ups. This review aims to illustrate the multimodality imaging appearances of rare adrenal medullary tumours, excluding the more common phaeochromocytomas, with clues to the diagnosis and to summarise relevant epidemiological and clinical data. Careful correlation of clinical presentation, hormone profile, and various imaging techniques narrow the differential diagnosis. Image-guided percutaneous adrenal biopsy can provide a definitive diagnosis, allowing for conservative management in selected cases. A close collaboration between the radiologist, endocrinologist, and surgeon is of the utmost importance in the management of these tumours. PMID:26944698

    Full Text Available Pure androgen-secreting adrenal adenoma is very rare, and its diagnosis remains a clinical challenge. Its association with resistant hypertension is uncommon and not well understood. We present an 18-year-old female with a 10-year history of hirsutism that was accidentally diagnosed with an adrenal mass during the evaluation of a hypertensive crisis. She had a long-standing history of hirsutism, clitorimegaly, deepening of the voice, and primary amenorrhea. She was phenotypically and socially a male. FSH, LH, prolactin, estradiol, 17-hydroxyprogesterone, and progesterone were normal. Total testosterone and DHEA-S were elevated. Cushing syndrome, primary aldosteronism, pheochromocytoma, and nonclassic congenital adrenal hyperplasia were ruled out. She underwent adrenalectomy and pathology reported an adenoma. At 2-month followup, hirsutism and virilizing symptoms clearly improved and blood pressure normalized without antihypertensive medications, current literature of this unusual illness and it association with hypertension is presented and discussed.

    2010-04-01

    A 15-year-old girl with Turner syndrome was unexpectedly found to have a left suprarenal mass. Extensive investigations showed a clinically and biochemically inapparent mass. Computed tomography disclosed a well-defined solid lesion in the left adrenal measuring 6.5 x 5 cm with minimal contrast enhancement. Laparoscopic adrenalectomy was done. Histologic examination revealed an encapsulated mass originated from the left adrenal medulla. Tumor tissue comprised abundant collagen fibers and spindloid cells admixed with mature ganglion cells. The tumor was diagnosed as left adrenal ganglioneuroma. According to literature, we report the eighth case of ganglioneuroma complicating Turner syndrome. Patients with this syndrome are predisposed to the development of neuroblastoma and related tumors. Reasons for this predisposition might relate to genetic and hormonal factors. Given that these tumors are often limited stage and of good prognosis, we recommend their screening in all patients with Turner syndrome.

    Primary adrenal leiomyosarcoma is a rare form of adrenal mesenchymal tumors. Immunohistochemistry (IHC) together with histology takes a major role in determining the tumor type and predicting their biological behavior and differentiating them from adrenal cortical carcinoma. Appropriate radiological investigation is necessary to rule out metastatic disease from primary tumors elsewhere in the body. In this case, we report a primary leiomyosarcoma of the adrenal gland in a 61-year-old Bahraini male clinically presumed to be a renal neoplasm. PMID:25685588

    Full Text Available Abstract Introduction Adrenal myelolipoma is a rare, benign neoplasm that is usually asymptomatic, unilateral and nonsecreting. It develops within the adrenal gland and is composed of mature adipose tissue with elements of the hematopoietic series. We describe the case of what is, to the best of our knowledge, one of the largest secreting adrenal myelolipomas reported in the literature. Case presentation A 52-year-old Caucasian man of medium build who had had moderate hypertension for three years presented to our hospital. He had no other significant symptoms. His hypertension was pharmacologically treated. He came to our hospital to undergo abdominal ultrasonography during a clinical checkup. The ultrasound scan showed the presence of a voluminous hyperechoic mass interposed between the spleen and the left kidney. It was reported as a myelolipoma of the left kidney on the basis of its structural characteristics and position. Computed tomography confirmed our diagnosis. All preoperative biochemical tests were normal, with the exception of high serum cortisol, which was being overproduced by the lesion and was probably responsible for the patient's hypertension. He underwent successful surgery, and his postoperative course was uneventful. The pathologic examination of the lesion confirmed the diagnosis of adrenal myelolipoma. The patient's blood pressure returned to within the normal range. Conclusions The "incidental" discovery of an adrenal mass requires careful diagnostic study to plan adequate therapeutic management. Both of the primary investigations at our disposal, ultrasound and blood tests (adrenal hormones, helped in rendering the diagnosis and allowed us to move toward the most appropriate treatment, taking into account the size of the tumor and its probable hormonal production.

    The adrenal is a small gland that escaped anatomic notice until the 16th century, and whose essential role in physiology was not established until the mid 19th century. Early studies were confounded by failure to distinguish the effects of the cortex from those of the medulla, but advances in steroid chemistry permitted the isolation, characterization and synthesis of many steroids by the mid 20th century. Knowledge of steroid structures, radiolabeled steroid conversions, and the identification of accumulated urinary steroids in diseases of steroidogenesis permitted a generally correct description of the steroidogenic pathways, but one confounded by the failure to distinguish species-specific differences. The advent of cloning technologies and molecular genetics rapidly corrected and clarified the understanding of steroidogenic processes. Our laboratory in San Francisco was one of several contributing to this effort, focusing on human steroidogenic enzymes, the genetic disorders in their biosynthesis and the transcriptional and post-translational mechanisms regulating enzyme activity.

  5. Arecoline inhibits catecholamine release from perfused rat adrenal gland

    Aim: To study the effect of arecoline, an alkaloid isolated from Areca catechu, on the secretion of catecholamines (CA) evoked by cholinergic agonists and the membrane depolarizer from isolated perfused rat adrenal gland. Methods: Adrenal glands were isolated from male Sprague-Dawley rats. The adrenal glands were perfused with Krebs bicarbonate solution by means of a peristaltic pump. The CA content of the perfusate was measured directly using the fluorometric method.Results: Arecoline (0.1-1.0 mmol/L) perfused into an adrenal vein for 60 min produced dose- and time-dependent inhibition in CA secretory responses evoked by acetylcholine (ACh) (5.32 mmol/L), 1.1-dimethyl-4-phenyl piperazinium iodide (DMPP) (100 μmol/L for 2 min) and 3-(m-choloro-phenyl-carbamoyl-oxy)-2-butynyl trimethyl ammonium chloride (McN-A-343) (100 μmol/L for 2 min). However, lower doses of arecoline did not affect CA secretion of high K+ (56 mmol/L); higher doses greatly reduced CA secretion of high K+. Arecoline also failed to affect basal catecholamine output. Furthermore, in adrenal glands loaded with arecoline (0.3 mmol/L), CA secretory response evoked by Bay-K-8644 (10 μmol/L), an activator of L-type Ca2+ channels, was markedly inhibited, whereas CA secretion by cyclopiazonic acid (10 μmol/L), an inhibitor of cytoplasmic Ca2+-ATPase, was not affected. Nicotine (30 μmol/L), which was peffused into the adrenal gland for 60min, however, initially enhanced ACh-evoked CA secretory responses. As time elapsed, these responses became more inhibited, whereas the initially enhanced high K+-evoked CA release diminished. CA secretion evoked by DMPP and McNA-343 was significantly depressed in the presence of nicotine. Conclusion:Arecoline dose-dependently inhibits CA secretion from isolated perfused rat adrenal gland evoked by activation of cholinergic receptors. At lower doses arecoline does not inhibit CA secretion through membrane depolarization, but at larger doses it does. This inhibitory

    Congenital adrenal hyperplasias (CAH) are a group of autosomal recessive defects in cortisol biosynthesis. Substantial progress has been made since the description of the first report, 150 years ago. This article reviews some of the recent advances in the genetics, diagnosis and treatment of CAH. In addition, we underline the aspects where further progress is required, including, among others, better diagnostic modalities for the mild phenotype and for some of the rare forms of disease, elucidation of epigenetic factors that lead to different phenotypes in patients with identical genotype and expending on treatment options for controlling the adrenal androgen excess.

    Full Text Available Adrenal myelolipomas are rare, small, benign, non-functioning tumors, which must be histopathologically differentiated from other tumors such as lipomas or liposarcomas. They are usually identified incidentally during autopsy, imaging or laparotomy. Occasionally, they may present acutely due to complications such as abdominal pain from retroperitoneal bleeding or systemic symptoms of infection. In differantial diagnosis, Magnetic Resonance Imaging may be useful to show characterize of tissue and relationship with other organs. We report a 66-year-old man with a giant adrenal myelolipoma clinically presenting with chronic mild postprandial pain with a brief review of the literature.

    Purpose: To report on an exceptional case of spontaneous, idiopathic, unilateral adrenal gland rupture that caused massive retroperitoneal hemorrhage. Methods and Results: US and CT were performed in a patient who presented with acute abdominal pain. Urgent adrenalectomy was required to prevent the blood loss from continuing. The CT findings were correlated with the histological findings. Conclusion: CT proved to be an accurate imaging modality by which to diagnose adrenal hemorrhage. The absence of irregular tissue enhancement showed that neoplasia was not the underlying cause of the hematoma. (orig.)

    Primary aldosteronism due to unilateral aldosterone-producing adenoma (APA) is a surgically curable form of hypertension. Bilateral APA can also be surgically curable in theory but few successful cases can be found in the literature. It has been reported that even using successful adrenal venous sampling (AVS) via bilateral adrenal central veins, it is extremely difficult to differentiate bilateral APA from bilateral idiopathic hyperaldosteronism (IHA) harbouring computed tomography (CT)-detectable bilateral adrenocortical nodules. We report a case of bilateral APA diagnosed by segmental AVS (S-AVS) and blood sampling via intra-adrenal first-degree tributary veins to localize the sites of intra-adrenal hormone production. A 36-year-old man with marked long-standing hypertension was referred to us with a clinical diagnosis of bilateral APA. He had typical clinical and laboratory profiles of marked hypertension, hypokalaemia, elevated plasma aldosterone concentration (PAC) of 45.1 ng dl(-1) and aldosterone renin activity ratio of 90.2 (ng dl(-1) per ng ml(-1 )h(-1)), which was still high after 50 mg-captopril loading. CT revealed bilateral adrenocortical tumours of 10 and 12 mm in diameter on the right and left sides, respectively. S-AVS confirmed excess aldosterone secretion from a tumour segment vein and suppressed secretion from a non-tumour segment vein bilaterally, leading to the diagnosis of bilateral APA. The patient underwent simultaneous bilateral sparing adrenalectomy. Histopathological analysis of the resected adrenals together with decreased blood pressure and PAC of 5.2 ng dl(-1) confirmed the removal of bilateral APA. S-AVS was reliable to differentiate bilateral APA from IHA by direct evaluation of intra-adrenal hormone production. PMID:26538381

    Full Text Available OBJECTIVE: To analyze the short term results of mitral valve repair in a consecutive series of mitral insufficiency patients from different ethiologies. METHODS: A retrospective study was made of 86 patients with mitral insufficiency operated on between May 1992 and May 2001 for mitral valve repair. Mitral insufficiency was severe in 77 patients and moderate in 9. The functional class of the patients was I in 4, II in 48, III in 29 and IV in 5 patients. The etiology was rheumatic in 47 (54.6% cases. RESULTS: Mitral valve repair was performed by only one procedure on the mitral valve in 6 patients, two procedures in 29, and three or more procedures in 51 (59.3% patients. Mitral annuloplasty was performedin 81 patients, with the Braile posterior pericardial ring being the mostcommonly used (87.2%. Hospital mortality was 3.5%. There was improvement in the funcional class in 79 (91.8% patients. Mitral valve function was normal in 80 (93% patients and moderate mitral insufficiency occurred in 6 patients. CONCLUSION: Mitral valve repair can be performed with low mortality (3.5% and high probability of valve function recovery (93%. It should be the procedure of choice in patients with mitral insufficiency.

    Full Text Available Schwannomas are rare tumors in the retroperitoneal location. They can pose a diagnostic dilemma when presenting as an adrenal mass lesion due to their imaging characteristics. We report two cases of juxta-adrenal schwannomas presenting as symptomatic adrenal mass lesions. In both the cases, the clinical examination and functional evaluation was unremarkable and the radiological examination revealed a mixed intense adrenal mass lesion in one case with predominantly hyperintense areas and a very hyperintense lesion in another, in T2-weighted images, mimicking a adrenocortical malignancy and a pheochromocytoma respectively. Both cases were treated by surgical excision. Histopathological examination established the correct diagnosis of schwannoma, which was confirmed by immunohistochemical staining. Juxta-adrenal schwannoma is rare tumors of the retroperitoneum, which should also be borne in mind whenever encountering large nonsecreting adrenal tumors. We report a unique imaging characteristic, which helps in preoperative identification these rare lesions.

    Chronic venous insufficiency of the lower limbs is very prevalent. In recent decades, Doppler ultrasound has become the method of choice to study this condition, and it is considered essential when surgery is indicated. This article aims to establish a method for the examination, including venous mapping and preoperative marking. To this end, we review the venous anatomy of the lower limbs and the pathophysiology of chronic venous insufficiency and explain the basic hemodynamic concepts and the terminology required to elaborate a radiological report that will enable appropriate treatment planning and communication with other specialists. We briefly explain the CHIVA (the acronym for the French term "cure conservatrice et hémodynamique de l'insuffisance veineuse en ambulatoire"=conservative hemodynamic treatment for chronic venous insufficiency) strategy, a minimally invasive surgical strategy that aims to restore correct venous hemodynamics without resecting the saphenous vein.

    Congenital adrenal hyperplasia (CAH) is characterized by decreased adrenal hormone production due to enzymatic defects and subsequent rise of adrenocorticotrophic hormone that stimulates the adrenal cortex to become hyperplastic, and sometimes tumorous. As the pathophysiology is basically a defect in the biosynthesis of cortisol, one may not consider CAH in patients with hypercortisolism. We report a case of a 41-yr-old man with a 4 cm-sized left adrenal tumorous lesion mimicking Cushing's syndrome who was diagnosed with CAH. He had central obesity and acanthosis nigricans involving the axillae together with elevated 24-hr urine cortisol level, supporting the diagnosis of Cushing's syndrome. However, the 24-hr urine cortisol was suppressed by 95% with the low dose dexamethasone suppression test. CAH was suspected based on the history of precocious puberty, short stature and a profound suppression of cortisol production by dexamethasone. CAH was confirmed by a remarkably increased level of serum 17-hydroxyprogesterone level. Gene mutation analysis revealed a compound heterozygote mutation of CYP21A2 (I173N and R357W). PMID:23166432

  15. Response of adrenal gland to whole body 60Co irradiation

    International Nuclear Information System (INIS)

    Whole body of the adult albino rates was exposed to 60Co radiation in a single dose of 600 R. Following irradiation the adrenal serotonin level was found higher till the end of 8th week except a fall on 14th day, whereas the blood 5HT level remained lower than the normal except a slight rise at the end of 1st week and dropped down at 14 days followed by a further rise. The blood catecholamine level was found increased at the end of 14th day followed by a fall at 4th and 8th weeks, but the levels were moving round the normal value. The histological studies of adrenal gland showed degranulation and hypertrophy of adrenal cortex and medullary cells at various intervals of post-irradiation. On the whole it is observed that maximum changes in the level of biogenic amines take place within 14 days after irradiation, and maximum rate of mortality also coincide with this period. Thus bringing out the fact that adrenal bioamines play an important role in the vital activities of the animals. (author)

    Copper (Cu) ion is an essential component of enzymes involved in catecholamine (CAT) metabolism. Copper deficiency (CuD) has been shown to affect the CAT content of brain (decreased norepinephrine (NE) and dopamine (DA)) and heart (increased DA and decreased NE). It is thus possible that plasma and adrenal CAT could be altered by CuD. The authors, then, investigated the effect of CuD on plasma and adrenal CAT in rats fed copper-deficient (0.6 ..mu..g Cu/g) or copper-supplemented (6.0 ..mu..g Cu/g) diets with either 62% starch (S) or fructose (F) as the carbohydrate source for 7 weeks after weaning. CuD was ascertained by decreased plasma Cu and ceruloplasmin activity. CuD increased the levels of all three CAT (NE, P < 0.001, epinephrine (E), P < 0.0001 and DA, P < 0.01) in plasma, but had no effect on adrenal CAT content. Dietary F had no significant effect on plasma CAT compared to S but did increase E in adrenal tissue (P < 0.001). They have previously demonstrated that CuD is accompanied by increased plasma glucose, triglyceride and cholesterol and decreased insulin. Thus, increased plasma CAT along with decreased plasma insulin may explain, in part, the glucose intolerance and abnormal lipid metabolism observed in CuD.

    Full Text Available A ganglioneuroma (GN is the rarest and most benign of the neuroblastic tumors and originates from neural crest cells wherever sympathetic nervous tissue exists, such as in the retroperitoneum and adrenal gland. The diagnosis can be very challenging, given the rarity and asymptomatic presentation of this neoplasia, and can be achieved only by means of histological evaluation. Although benign, a few cases of metastatic GNs have been reported in the literature. The prognosis, however, seems to be excellent after surgical resection. We describe a rare case of multifocal retroperitoneal GN, diagnosed incidentally in a 46-year-old woman, with para-aortic and adrenal localizations. After intraoperative pathological diagnosis was made, complete excision of all the visible masses was performed. The postoperative period was uneventful and she was recurrence free 3 months after surgery. To our knowledge, this is the first case report of a multifocal retroperitoneal GN. Among the broad differential diagnoses of adrenal incidentalomas, an adrenal location of neuroblastic tumors should not be forgotten.

    Cardiac overstimulation by the sympathetic nervous system (SNS) is a salient characteristic of heart failure, reflected by elevated circulating levels of catecholamines. The success of beta-adrenergic receptor (betaAR) antagonists in heart failure argues for SNS hyperactivity being pathogenic; however, sympatholytic agents targeting alpha2AR-mediated catecholamine inhibition have been unsuccessful. By investigating adrenal adrenergic receptor signaling in heart failure models, we found molecular mechanisms to explain the failure of sympatholytic agents and discovered a new strategy to lower SNS activity. During heart failure, there is substantial alpha2AR dysregulation in the adrenal gland, triggered by increased expression and activity of G protein-coupled receptor kinase 2 (GRK2). Adrenal gland-specific GRK2 inhibition reversed alpha2AR dysregulation in heart failure, resulting in lowered plasma catecholamine levels, improved cardiac betaAR signaling and function, and increased sympatholytic efficacy of a alpha2AR agonist. This is the first demonstration, to our knowledge, of a molecular mechanism for SNS hyperactivity in heart failure, and our study identifies adrenal GRK2 activity as a new sympatholytic target.

    2016-08-01

    The circulating catecholamines (CAs) epinephrine (Epi) and norepinephrine (NE) derive from two major sources in the whole organism: the sympathetic nerve endings, which release NE on effector organs, and the chromaffin cells of the adrenal medulla, which are cells that synthesize, store and release Epi (mainly) and NE. All of the Epi in the body and a significant amount of circulating NE derive from the adrenal medulla. The secretion of CAs from adrenal chromaffin cells is regulated in a complex way by a variety of membrane receptors, the vast majority of which are G protein-coupled receptors (GPCRs), including adrenergic receptors (ARs), which act as "presynaptic autoreceptors" in this regard. There is a plethora of CA-secretagogue signals acting on these receptors but some of them, most notably the α2ARs, inhibit CA secretion. Over the past few years, however, a few new proteins present in chromaffin cells have been uncovered to participate in CA secretion regulation. Most prominent among these are GRK2 and β-arrestin1, which are known to interact with GPCRs regulating receptor signaling and function. The present review will discuss the molecular and signaling mechanisms by which adrenal chromaffin cell-residing GPCRs and their regulatory proteins modulate CA synthesis and secretion. Particular emphasis will be given to the newly discovered roles of GRK2 and β-arrestins in these processes and particular points of focus for future research will be highlighted, as well.

    The coexistence of myelolipoma within adrenal cortical adenoma is extremely rare, for both tumors present usually as separate entities. There are only 16 such cases reported worldwide. To the best of our knowledge, the case we reported here is the first one of myxoid adrenal cortical adenoma associated with myelolipoma reported. A 32-year-old Chinese woman with 4-year history of hypertension was presented in our study. Computed tomography (CT) of the abdomen showed a large heterogeneously-enhancing mass (4.5cm in diameter) in the left suprarenal region. Clinical history and laboratory results suggest a metabolic disorder as Conn's syndrome. The patient underwent a left adrenalectomy, and a histopathological study confirmed the mass to be a myxoid adrenal cortical adenoma containing myelolipoma. The patient was postoperatively well and discharged uneventfully. In the present case report, we also discuss the etiology of simultaneous myelolipoma and adrenal adenoma associated with Conn's syndrome, and the methods of the diagnosis and differential diagnosis.

    Congenital adrenal hyperplasia (CAH) is an inherited autosomal recessive disorder characterized by insufficient production of cortisol. The aim of this case report was to present a child with CAH, premature exfoliation of primary teeth and accelerated eruption of his permanent teeth related to bone resorption. A 4.5-year-old Caucasian boy with CAH and long-term administration of glucocorticoids was referred for dental restoration. Clinical examination revealed primary molars with worn stainless steel crowns, severe attrition of the upper canines, and absence of the upper incisors. Before the completion of treatment, abnormal mobility of the first upper primary molars and the lower incisors was detected, and a few days later the teeth exfoliated prematurely. Histologic examination revealed normal tooth structure. Alkaline phosphatase and blood cells values were normal. Eruption of the permanent dentition was also accelerated. Tooth mobility was noticed in the permanent teeth as soon as they erupted, along with bone destruction. Examination revealed an elevated level of receptor activator of nuclear factor-κB ligand and lower-than-normal osteoprotegerin and vitamin D levels. The patient was treated with vitamin D supplements, and his teeth have been stable ever since. CAH is a serious chronic disorder appearing in children with accelerated dental development and possibly premature loss of primary teeth.

  9. Pubic and sacral insufficiency fractures: clinical course and radiologic findings

    International Nuclear Information System (INIS)

    Distinctive vertical insufficiency fractures of the pelvis were found in nine osteopenic patients. Each patient had subacute pelvic pain without antecedent trauma. The sacral fractures healed fairly quickly, but the pubic fractures often had a protracted course. All nine patients had skeletal demineralization due to metabolic bone disease, radiation therapy, or multiple myeloma. Recognition of the association between public and sacral insufficiently fractures should aid in recognizing the diffuse nature of the skeletal disease so that unnecessary biopsy of the fracture sites can be avoided. Plain films, tomographic scans, and radionuclide bone scans are reviewed

    AIM:To describe the role of nuclear imaging modalities using nor-cholesterol,metaiodobenzylguanidine(MIBG)and fluorine-deoxy-glucose(FDG)in adrenal tumors for lesion characterization in comparison with magnetic resonance(MR).METHODS:Population was classified in group 1 consisting of 30 patients with non-hypersecreting unilateral adrenal masses,in group 2 consisting of 34 patients with hypersecreting(n=19)or non-hypersecreting(n=15)adrenal adenomas and in group 3 consisting of 18 patients with chromaffin-tissue tumors(CTT),of which 14 were pheochromocytomas while 4 were paragangliomas(n=4).All patients underwent MR and nuclear studies(nor-cholesterol,MIBG and FDG).Pathology samples(n=63)or follow-up data in adenomas(n=19)were used as standard of reference forimaging studies interpretation.RESULTS:In group 1,MR findings were not highly accurate for lesion characterization,while the results of nuclear scans showed abnormal nor-cholesterol,MIBG and FDG concentration in all cases of adenomas,pheos and malignant tumors,respectively.In group 2,no differences in MR parameters were found between hyperfunctioning and non-hyperfunctioning adenomas,while nor-cholesterol uptake was significantly higher in hyperfunctioning compared to non-hyperfunctioning lesions.In group 3,no differences in MR parameters were found between benign and malignant CCT,while MIBG uptake was significantly higher in malignant compared to benign tumors.CONCLUSION:On the basis of our findings,nuclear imaging modalities using specific target agents are able to better characterize adrenal tumors,compared with MR.In particular,radionuclide techniques are able to identify the nature of adrenal incidentalomas and to differentiate between hypersecreting and non-hypersecreting adenomas as well as between benign and malignant CTT.

  11. Aldo-keto reductases 1B in adrenal cortex physiology

    2016-07-01

    Full Text Available Aldose reductase proteins are cytosolic monomeric enzymes, belonging to the aldo-keto reductase (AKR superfamily. They perform oxidoreduction of carbonyl groups from a wide variety of substrates such as aliphatic and aromatic aldehydes or ketones. The Aldose reductase subgroup (AKR1B is one of the most characterized because of its involvement in human diseases such as diabetic complications resulting from the ability of its human archetype AKR1B1 to reduce glucose into sorbitol. However the issue of AKR1B function in non pathologic condition remains poorly resolved. Adrenal steroidogenesis is strongly associated with high production of endogenous harmful lipid aldehyde by-products including isocaproaldehyde (4-methylpentanal derived from cholesterol side chain cleavage (the first step of steroid synthesis and 4-hydroxynonenal (4- HNE that can both be reduced by AKR1B proteins. More recently, some AKR1B isoforms have been shown to be endowed with prostaglandin F synthase activity, suggesting that in addition to possible scavenger function, they could instigate paracrine signals. Interestingly, previous studies have established that the adrenal gland is one of the major site for human and murine AKR1B expression suggesting that their detoxifying/signaling activity could be specifically required for the correct handling of adrenal function. Moreover chronic effects of ACTH result in a coordinated regulation of genes encoding the steroidogenic enzymes and some AKR1B isoforms.This review presents the molecular mechanisms accounting for the adrenal specific expression of some AKR1B genes. Using data from recent mouse genetic models, we will try to connect their enzymatic properties and regulation with adrenal functions.

  12. Clinical, chromosomal and endocrine studies for congenital adrenal hyperplasia

    International Nuclear Information System (INIS)

    Severe forms of congenital adrenal hyperplasia are potentially fatal if unrecognized and untreated. The aim of this study was to clarify the clinical presentation together with the chromosomal and laboratory associations in this syndrome. Twenty four patients diagnosed as congenital adrenal hyperplasia were referred from Children's Hospital, Cairo University, Egypt, for hormonal and chromosomal workup. The age ranged from eight months to 19 years with mean age of 3.18 years. Twenty two patients were diagnosed as classic congenital adrenal hyperplasia (CAH) syndrome. Severe salt wasting form was present in ten patients whereas simple virilisation was the presenting manifestation in twelve patients. Two patients presented as late onset congenital adrenal hyperplasia (LOCAH). The sex of rearing was female in 18 cases and male in six cases. Genitography and sonography confirmed the presence of female internal organs in all cases. Advanced bone age was evident by radiographic studies. Although the karyotyping was 46,XX in all cases, the diagnosed correct sex was delayed in six cases. Serum concentrations of 17-hydroxyprogesterone (17.OH.P), dehydroepiandrosterone sulfate (DHEAS), delta, 4-androstenedione (D4A), testosterone (T) and 11-deoxycortisol were all elevated as compared to controls. It was found that the adrenal androgens DHEAS, D4A and T were more elevated in salt losers when compared to simple virilising patients. However, this difference was statistically non-significant. The present study demonstrates that the clinical examination and laboratory investigations are necessary for the early detection and treatment of these cases to avoid major medical and psychological problems for the patients and their parents

The aim of this study is to throw light on the clinical presentation together with chromosomal and laboratory associations in this syndrome. Twenty four patients diagnosed as congenital adrenal hyperplasia were referred from the Diabetic Endocrine Metabolic Pediatric Unit [DEMPU], Children's Hospital, Cairo University for hormonal and chromosomal workup. Twenty two patients were diagnosed as classic congenital adrenal hyperplasia (CAH) syndrome. Sever salt wasting form was present in ten patients whereas simple virilization was the presenting manifestation in twelve patients. Two patients presented as late onset congenital adrenal hyperplasia (LOCAH). The mean age was 3.18 years, ranging from eight months to 19 years. The sex of rearing was Female in 18 cases and male in six cases. Genitography and sonography confirmed the presence of female internal organs in all cases. Advanced bone age was evident by radiographic studies. Although the karyotyping was (46,XX) in all cases, the correct sex diagnosis was delayed in 6 cases. Serum concentrations of 17-hydroxyprogesterone (17.OH.P); Dehydroepiandrosterone sulfate (DHEAS); Delta,4-androstenedione (D 4 A); Testosterone and 11-deoxycortisol were all elevated in relation to controls. We found that the adrenal androgens DHEAS, delta 4A, and T were more elevated in salt losers when compared to simple virilizing patients. However, this difference was not of statistical significance. The present study demonstrates that clinical examination and laboratory investigations are necessary for early detection and treatment of hese cases to avoid major medical and psychological problems for the patients and their parents.

    Full Text Available Abstract Background Our laboratory has shown that a locus on the SHR Y chromosome increases blood pressure (BP in the SHR rat and in WKY rats that had the SHR Y chromosome locus crossed into their genome (SHR/y rat. A potential candidate for this Y chromosome hypertension locus is Sry, a gene that encodes a transcription factor that is responsible for testes development and the Sry protein may affect other target genes. Methods The following study examined if exogenous Sry would elevate adrenal Th, adrenal catecholamines, plasma catecholamines and blood pressure. We delivered 10 μg of either the expression construct, Sry1/pcDNA 3.1, or control vector into the adrenal medulla of WKY rats by electroporation. Blood pressure was measured by the tail cuff technique and Th and catecholamines by HPLC with electrochemical detection. Results In the animals receiving Sry there were significant increases after 3 weeks in resting plasma NE (57% and adrenal Th content (49% compared to vector controls. BP was 30 mmHg higher in Sry injected animals (160 mmHg, p Conclusion These results provide continued support that Sry is a candidate gene for hypertension. Also, these results are consistent with a role for Sry in increasing BP by directly or indirectly activating sympathetic nervous system activity.

    To give a help in the interpretation of cardiac cine-MR examination, the extent, shape, and timing of appearance of signal void regions near atrioventricular(A-V) valve prospectively evaluate in the healthy population. Using an axial gradient-echo technique with small flip angle, repetition time(TR) of 36 msec and echo time(TE) of 22 msec, 20 volunteers without known valvular abnormalities undertook cardiac cine-MR imaging including atrioventricular valve areas. Transient signal void was observed within the near the tricuspid(13/20 = 65%) and mitral valves(9/20 = 45%), respectively, which is so called {sup p}hysioloic atrioventricular valvular insufficiency{sup .} Eight subjects revealed the signal void areas near both tricuspid and mitral valves but, 5 subjects did not show any evidence of physiologic insufficiency. This physiologic condition does not extend more than 1 cm proximal to A-V valve plane and is generally observed only during early systole. Its morphology is semilunar or triangular configuration with the base to the valve plane in most cases of normal tricuspid insufficiency and small globular appearance in most cases of normal mitral insufficiency. Awareness of normal signal void areas near the A-V valve and their characteristics is critical in the interpretation of cardiac cine MR examinations and maybe helpful in the study of the normal cardiac physiology.

    Sacral insufficiency fractures are a well recognised cause for low back, buttock and groin pain in the elderly. However, over a 4 year period, four patients have presented with symptoms of cauda equina syndrome, who were found on investigation to have acute sacral insufficiency fracture without any other aetiological spinal abnormality. Four patients who presented to the spinal surgeons of our institution with symptoms of cauda equina syndrome were referred for spinal MR. Sagittal and axial T1 and T2 weighted turbo spin echo sequences of the lower thoracic and lumbar spine were performed on all patients. Subsequent studies included MR of the sacrum supplemented where appropriate by CT and technetium MDP bone scintigraphy. No evidence of a compressive lesion of the lower thoracic or lumbar spine was present in any of the four patients. Dedicated MR examination of the sacrum in these patients revealed unilateral acute insufficiency fractures involving zone 1 from S1 to S3 extending from the sacro-iliac joint to the lateral margin of the sacral foramen. There was no evidence of compression of the sacral nerve roots. The possible mechanism for the symptomatic presentation is discussed. Sacral insufficiency fractures should be excluded in elderly or osteoporotic patients presenting with cauda equina syndrome who have no evidence of compression in the thoraco-lumbar MR studies.

    1999-01-01

    Chronic renal insufficiency raises an ever-increasing public-health problem due to its permanent growth among the general population and the escalating cost of renal replacement therapies. By the end of 1995 there were close to 33,700 patients with end-stage renal failure maintained alive with renal replacement methods in France. About 11,200 had a functioning kidney graft, whereas 22,500 were treated with various dialysis techniques, in and out-of-center hemodialysis and peritoneal dialysis. An optimal health policy should contribute both to prevent renal insufficiency and offer each patient his/her best specific mode of treatment at the lowest cost for the community. Renal transplantation should be much more widely promoted and utilized through measures aiming at reducing the too high refusal rates of organ donation in subjects with brain-death. Promotion and extension of out-of-center dialysis techniques are also necessary. Design of reliable epidemiological studies dealing not only with end-stage renal failure patients but with the early stage and time-course of renal insufficiency is also mandatory. A deeper investigation in the area of renal-risk factors and a qualified follow-up of patients with mild/moderate renal insufficiency are essential to avoid or delay an evolution towards end-stage renal failure. Prevention of renal fibrosis has a central role in such a long-term public health-policy. PMID:10371761

  19. Aneuploidy as a mechanism of adaptation to telomerase insufficiency.

    2016-08-01

    Cells' survival is determined by their ability to adapt to constantly changing environment. Adaptation responses involve global changes in transcription, translation, and posttranslational modifications of proteins. In recent years, karyotype changes in adapting populations of single cell organisms have been reported in a number of studies. More recently, we have described aneuploidy as an adaptation mechanism used by populations of budding yeast Saccharomyces cerevisiae to survive telomerase insufficiency induced by elevated growth temperature. Genetic evidence suggests that telomerase insufficiency is caused by decreased levels of the telomerase catalytic subunit Est2. Here, we present experiments arguing that the underlying cause of this phenomenon may be within the telomerase RNA TLC1: changes in the expression of TLC1 as well as mutations in the TLC1 template region affect telomere length equilibrium and the temperature threshold for the induction of telomerase insufficiency. We discuss what lies at the root of telomerase insufficiency, how cell populations overcome it through aneuploidy and whether reversible aneuploidy could be an adaptation mechanism for a variety of environmental stresses.

    : By definition, an adrenal incidentaloma is an asymptomatic adrenal mass detected on imaging not performed for suspected adrenal disease. In most cases, adrenal incidentalomas are nonfunctioning adrenocortical adenomas, but may also represent conditions requiring therapeutic intervention (e.g. adrenocortical carcinoma, pheochromocytoma, hormone-producing adenoma or metastasis). The purpose of this guideline is to provide clinicians with best possible evidence-based recommendations for clinical management of patients with adrenal incidentalomas based on the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. We predefined four main clinical questions crucial for the management of adrenal incidentaloma patients, addressing these four with systematic literature searches: (A) How to assess risk of malignancy?; (B) How to define and manage low-level autonomous cortisol secretion, formerly called 'subclinical' Cushing's syndrome?; (C) Who should have surgical treatment and how should it be performed?; (D) What follow-up is indicated if the adrenal incidentaloma is not surgically removed? SELECTED RECOMMENDATIONS: (i) At the time of initial detection of an adrenal mass establishing whether the mass is benign or malignant is an important aim to avoid cumbersome and expensive follow-up imaging in those with benign disease. (ii) To exclude cortisol excess, a 1mg overnight dexamethasone suppression test should be performed (applying a cut-off value of serum cortisol ≤50nmol/L (1.8µg/dL)). (iii) For patients without clinical signs of overt Cushing's syndrome but serum cortisol levels post 1mg dexamethasone >138nmol/L (>5µg/dL), we propose the term 'autonomous cortisol secretion'. (iv) All patients with '(possible) autonomous cortisol' secretion should be screened for hypertension and type 2 diabetes mellitus, to ensure these are appropriately treated. (v) Surgical treatment should be considered in an individualized approach in patients with

We predefined four main clinical questions crucial for the management of adrenal incidentaloma patients, addressing these four with systematic literature searches: (A) How to assess risk of malignancy?; (B) How to define and manage low-level autonomous cortisol secretion, formerly called 'subclinical' Cushing's syndrome?; (C) Who should have surgical treatment and how should it be performed?; (D) What follow-up is indicated if the adrenal incidentaloma is not surgically removed? SELECTED RECOMMENDATIONS: (i) At the time of initial detection of an adrenal mass establishing whether the mass is benign or malignant is an important aim to avoid cumbersome and expensive follow-up imaging in those with benign disease. (ii) To exclude cortisol excess, a 1mg overnight dexamethasone suppression test should be performed (applying a cut-off value of serum cortisol ≤50nmol/L (1.8µg/dL)). (iii) For patients without clinical signs of overt Cushing's syndrome but serum cortisol levels post 1mg dexamethasone >138nmol/L (>5µg/dL), we propose the term 'autonomous cortisol secretion'. (iv) All patients with '(possible) autonomous cortisol' secretion should be screened for hypertension and type 2 diabetes mellitus, to ensure these are appropriately treated. (v) Surgical treatment should be considered in an individualized approach in patients with

  2. Prevention of insufficient team monitoring among nuclear power plant operators

    International Nuclear Information System (INIS)

    Earlier studies showed that the most common human errors involving operators at overseas nuclear power plants were those due to insufficient team monitoring, namely errors subsequently committed by superiors or fellow workers rather than an initial error committed by an operator. Although cases of insufficient team monitoring have rarely been reported in Japan, such faults could occur judging from the results of simulator training for operators. We therefore examined possible solutions to this problem. Using Rasmussen's model of human behavior, we analyzed the cases of insufficient team monitoring identified by instructors based on their experience in training. Analyses revealed that errors occur when an operator as a member of a team has gained a wrong situation awareness and this wrong situation awareness has not been corrected in the subsequent team action. The cases of insufficient team monitoring that were found during training can be classified into five types: the intuition type, the labyrinth type, the underestimation type, the dependence-on-experienced-operators type, and the complacency type. Problems identified in these five types of insufficient team monitoring have been analyzed using a newly developed team monitoring behavior model. Common factors that have been identified as the causes of errors committed during busy hours such as an emergency are: (1) the procedures are difficult to use; (2) necessary information cannot be retrieved easily; and (3) the procedure places as undue burden on a shift supervisor. These factors must be improved. Accordingly, we propose adopting a set of remedial measures: (1) the preparation of an easy-to-use procedure that sets forth instructions to be given by a shift supervisor; (2) the preparation of educational materials that are effective in assessing the progress of an event and gaining a broad overview of the situation; and (3) the sharing of responsibility and the delegation of authority to alleviate the burden on

    Full Text Available Abstract Introduction To date, there have been no reports on the prevalence of adrenal masses in type 2 diabetic patients. The present study aimed to evaluate the prevalence of adrenal incidentaloma in type 2 diabetic patients in Japan. Subjects We retrospectively evaluated the presence of adrenal masses using abdominal CT scans in 304 type 2 diabetic patients. In those with adrenal masses, we examined the hormone production capacity of the adrenal mass. Results Fourteen patients (4.6% had an adrenal mass. Hormonal analysis identified one case as having subclinical Cushing's syndrome, two with primary aldosteronism. Eleven cases had non-functioning masses. Discussion The reported prevalence of adrenal incidentaloma in normal subjects is 0.6-4.0% in abdominal CT scan series. Our results show a relatively high prevalence of adrenal tumors in diabetic patients. On the other hand, the frequency of functional adenoma in diabetic patients is 21.4%, which is similar to that of normal subjects. Conclusion Although further studies are needed to evaluate the prevalence of adrenal tumors in diabetic patients, our data suggest that evaluation of the presence of adrenal masses may be needed in patients with type 2 diabetes mellitus.

    {sup 131}I-6-{beta}-iodomethyl-19-norcholesterol (NP-59) has an advantage to assess adrenal dysfunction caused by adrenal cortical disorders. The aim of this study is to evaluate the clinical usefulness of NP-59 scintigraphy in each adrenal disease. Ten patients who did eleven NP-59 adrenal scintigraphies at Dong-A University Hospital from March 1990 to December 1996 were selected as the subject. Among the subject there were 5 cases of Cushing's syndrome, 2 cases of incidentaloma, 1 case of metastatic adrenal tumor, liver cirrhosis with hirsutism and hypertension respectively. Among 5 cases of Cushing's syndrome, there were 2 cases of Cushing's disease, 2 cases of adrenal adenoma and 1 case of adrenal carcinoma. There are no disagreement between clinical diagnosis and scan finding in Cushing's syndrome. In 2 incidentaloma cases, even though one is interpretated as a functioning tumor, both of 2 cases could avoid unnecessary biopsy according to scintigraphy result. One case of hirsutism, clinically adrenal originated, revealed the normal scintigraphic finding after dexamethasone suppression scan. It could suggest that the etiology of hirsutism was extra-adrenal origin. One case of hypertension took the study to exclude the possibility of primary aldosteronism. Normal suppression scan finding revealed that primary aldosteronism did not exist in this case. In conclusion, NP-59 scintigraphy was very useful in diagnosis and differential diagnosis of Cushing's syndrome and it could avoid unnecessary biopsy in the incidental adrenal tumor.

  5. Prevalence of ovarian adrenal rest tumours and polycystic ovaries in females with congenital adrenal hyperplasia: results of ultrasonography and MR imaging

    International Nuclear Information System (INIS)

    The aim of the investigation was to assess the prevalence of ovarian adrenal rest tumours and polycystic ovaries in female patients with congenital adrenal hyperplasia (CAH). Thirteen female CAH patients (median age 19.8 years, range 14.8-23.5 years) underwent transvaginal (n=6) or transabdominal (n=7) ultrasonography by a gynaecologist and MR imaging (n=13) of the ovaries (pre and post contrast-enhanced T1- and T2-weighted images). Ovarian adrenal rest tumours were defined as small hypoechoic and multifocal nodules on ultrasound and isointense lesions on T1- and hypointense on T2-weighted MR images (derived from characteristics of testicular adrenal rest tumours). Polycystic ovaries were defined as the presence of ≥10 follicles arranged peripherally around or scattered throughout increased stroma. No ovarian adrenal rest tumours were found either on ultrasound, or by MR imaging. Polycystic ovaries were found in 2 of the 13 patients (15.4%), both with ultrasound and MR. No ovarian adrenal rest tumours were detected in these female CAH patients, which suggests that ovarian adrenal rest tumours in CAH females are rare. The prevalence of polycystic ovaries corresponded to that in the general population. From these results, we would suggest that routine ovarian imaging in CAH females is not indicated. However, when ovarian dysfunction is present, ovarian imaging is advised, first by ultrasonography, to detect ovarian adrenal rest tumours or polycystic ovaries. (orig.)

    Full Text Available Lung cancer is one of the leading causes of cancer deaths worldwide. Metastatic spreads of lung cancer are often found in the adrenal glands, bone, liver, brain and kidneys; the gastrointestinal tract is less commonly involved. However, according to some reports in the literature, the incidence of gastrointestinal metastases, most of them asymptomatic, might be as frequent as 11% in autopsy studies of lung cancer, which suggests that this condition is not as rare as it was previously considered. We report a very rare case of small cell lung cancer with a solitary gastric metastasis mimicking an adrenal tumor which was belatedly diagnosed due to its unusual presentation and treated actively with surgery and chemotherapy, achieving a relatively favorable outcome.

  9. Prenatal treatment of congenital adrenal hyperplasia: risks outweigh benefits.

    2013-05-01

    Prenatal treatment of congenital adrenal hyperplasia by administering dexamethasone to a woman presumed to be carrying an at-risk fetus has been described as safe and effective in several reports. A review of data from animal experimentation and human trials indicates that first-trimester dexamethasone decreases birthweight; affects renal, pancreatic beta cell, and brain development; increases anxiety; and predisposes to adult hypertension and hyperglycemia. In human studies, first-trimester dexamethasone is associated with orofacial clefts, decreased birthweight, poorer verbal working memory, and poorer self-perception of scholastic and social competence. Numerous medical societies have cautioned that prenatal treatment of congenital adrenal hyperplasia with dexamethasone should only be done in prospective clinical research settings with institutional review board approval, and therefore is not appropriate for routine community practice.

    Science.gov (United States)

    Handa, Robert J; Weiser, Michael J

    2014-04-01

    The hypothalamo-pituitary-adrenal (HPA) axis represents a complex neuroendocrine feedback loop controlling the secretion of adrenal glucocorticoid hormones. Central to its function is the paraventricular nucleus of the hypothalamus (PVN) where neurons expressing corticotropin releasing factor reside. These HPA motor neurons are a primary site of integration leading to graded endocrine responses to physical and psychological stressors. An important regulatory factor that must be considered, prior to generating an appropriate response is the animal's reproductive status. Thus, PVN neurons express androgen and estrogen receptors and receive input from sites that also express these receptors. Consequently, changes in reproduction and gonadal steroid levels modulate the stress response and this underlies sex differences in HPA axis function. This review examines the make up of the HPA axis and hypothalamo-pituitary-gonadal (HPG) axis and the interactions between the two that should be considered when exploring normal and pathological responses to environmental stressors.

  11. Retroperitoneal extra-adrenal paraganglioma: a rare but important diagnosis.

    LENUS (Irish Health Repository)

    Ahmad, S

    2012-01-31

    BACKGROUND: Extra-adrenal paragangliomas of the retroperitonium are infrequently diagnosed. Their malignant behaviour cannot be predicted on initial clinical and histological assessment. These tumours have higher propensity for subsequent metastasis compared with pargangliomas at other sites. AIM: We aim to describe a case report of an incidental finding of left retroperitoneal paraganglioma in a young man who presented with right flank pain. We also aim to emphasize the importance of diagnosis and the malignant potential of these tumours. METHOD: Patient\\'s clinical notes, operative findings, imaging studies and laboratory investigations including histology results were reviewed. A literature search was done to look into the incidence, presentation, follow-up plan and treatment options for these tumours. CONCLUSION: Surgical resection is the only available curative option for extra-adrenal paragangliomas. Metastasis is observed years after surgery, hence long-term follow-up is required.

    Teratomas are unusual tumours that derived from totipotent cells with their origin from more than one or usually all three germ cells. Here authors are presenting a case of primary retroperitoneal tumour that is a rare clinical entity. A 19-year-old male presented with right lumbar pain and was found to have complex cyst with large calcification in right adrenal gland on imaging. Intraoperatively, he was found to have a solid mass with areas of soft consistency, which was excised en bloc. On gross examination, the cyst contained pieces of bone, few teeth, and hairs entangled in mucinous material. On histological evaluation, it was confirmed to be mature teratoma arising from the right adrenal gland. He made uneventful recovery and was kept well on annual follow-up.

  13. Biosynthesis and metabolism of steroid hormones by human adrenal carcinomas

    Directory of Open Access Journals (Sweden)

    Brown J.W.

    2000-01-01

    Full Text Available Over a 15-year period, our university-based laboratory obtained 125 adrenal tumors, of which 15 (12% were adrenal cortical carcinomas. Of these, 6 (40% of the carcinomas occurred in patients with clear clinical manifestations of steroid hormone excess. Adrenal cortical carcinoma cells derived from the surgically resected tumors in 4 of these patients were isolated and established in primary culture. Radiotracer steroid interconversion studies were carried out with these cultures and also on mitochondria isolated from homogenized tissues. Large tumors had the lowest steroidogenic activities per weight, whereas small tumors had more moderately depressed enzyme activities relative to cells from normal glands. In incubations with pregnenolone as substrate, 1 mM metyrapone blocked the synthesis of corticosterone and cortisol and also the formation of aldosterone. Metyrapone inhibition was associated with a concomitant increase in the formation of androgens (androstenedione and testosterone from pregnenolone. Administration of metyrapone in vivo before surgery in one patient resulted in a similar increase in plasma androstenedione, though plasma testosterone levels were not significantly affected. In cultures of two of four tumors examined, dibutyryl cAMP stimulated 11ß-hydroxylase activity modestly; ACTH also had a significant stimulatory effect in one of these tumors. Unlike results obtained with normal or adenomatous adrenal cortical tissues, mitochondria from carcinomatous cells showed a lack of support of either cholesterol side-chain cleavage enzyme complex or steroid 11ß-hydroxylase activity by Krebs cycle intermediates (10 mM isocitrate, succinate or malate. This finding is consistent with the concept that these carcinomas may tend to function predominantly in an anaerobic manner, rather than through the oxidation of Krebs cycle intermediates.

    Congenital adrenal hyperplasia (CAH) is a group of recessively inherited disorders. More than 90% of all cases of CAB are caused by 21-hydroxylase deficiency. This enzyme deficiency results in reduced ability to synthesize cortisol and aldosterone and at the same time increased secretion of androgens. There is a wide spectrum of severity of the disease. The most severe forms of CAH are life-threatening, with the risk of a salt crisis in the neonatal period. CAH has special i...

    International Nuclear Information System (INIS)

    A 53-year-old woman developed a subchondral insufficiency fracture of the right femoral head after undergoing a liver transplantation. Radiographs obtained at her first visit demonstrated a slight subchondral collapse in the superolateral portion of the femoral head. Magnetic resonance imaging (MRI) disclosed an irregular, discontinuous, low-intensity band on the T1-weighted image. After 7 months of conservative treatment, the hip pain and the radiograph abnormalities had both disappeared. On the follow-up T1-weighted MR image obtained 17 months after the onset, the band of low signal intensity was not obvious. A subchondral insufficiency fracture is one of the diagnoses to be considered in patients presenting with hip pain after a liver transplantation. (orig.)

  3. Adrenal incidentaloma imaging – the first steps in therapeutic management

    International Nuclear Information System (INIS)

    The term “adrenal incidentaloma” refers to clinically unapparent adrenal mass detected during imaging examination performed for reasons other than the evaluation of adrenal glands. These tumors must be carefully examined in order to assess the indications for surgical treatment. The main method of finding evidence of potential malignancy in these lesions is computed tomography (CT), before and after i.v. contrast media enhancement. Density of a malignant lesion is higher than 10 HU and the relative percentage washout is less than 40% at 10 min. Other useful methods utilized in tumor assessment, include magnetic resonance imaging (MRI), scintigraphy techniques (SPECT) and PET. Basal hormonal investigations include urine and plasma catecholamines with their metabolites, plasma cortisol before and after dexamethasone administration, plasma renin activity and aldosterone level. Cases not suitable for surgery should be followed with repeat imaging techniques and hormonal testing at the recommended 6, 12, and 24 months. Surgery should be performed when tumor growth rate exceeds 0,8 cm per year

Thus, basic research areas, such as morphology, become necessary to provide the applied areas with knowledge. Aiming to contribute to the knowledge on the vascular arrangements of the adrenal glands, 30 ostriches (Struthio camelus were used, four days old, who had their arterial components marked with a 50% stained aqueous solution of Neoprene Latex ¨ 450 ¨ and fixed in a 10% diluted solution of formaldehyde. The coelomic cavity was exposed for identifying these glands, which are paired organs that are covered by loose connective tissue, symmetrically arranged in the two antimeres, laterally to the descending aorta, caudally to the lungs, and cranio-medially to the cranial lobes of the kidneys. The arterial blood supply, in both antimeres, is derived from the right and left adrenal arteries, the right and left cranial renal artery branches, and the right branches of the descending aorta. Regardless of the origin, the number of branches going to the adrenal glands ranged from one to two and one to three respectively, in the left and right antimeres.

    Purpose: To evaluate a retrospective single-institution outcome after hypofractionated stereotactic body radiotherapy (SBRT) for adrenal metastases. Methods and Materials: Between February 2002 and December 2009, we treated 48 patients with SBRT for adrenal metastases. The median age of the patient population was 62.7 years (range, 43-77 years). In the majority of patients, the prescription dose was 36 Gy in 3 fractions (70% isodose, 17.14 Gy per fraction at the isocenter). Eight patients were treated with single-fraction stereotactic radiosurgery and forty patients with multi-fraction stereotactic radiotherapy. Results: Overall, the series of patients was followed up for a median of 16.2 months (range, 3-63 months). At the time of analysis, 20 patients were alive and 28 patients were dead. The 1- and 2-year actuarial overall survival rates were 39.7% and 14.5%, respectively. We recorded 48 distant failures and 2 local failures, with a median interval to local failure of 4.9 months. The actuarial 1-year disease control rate was 9%; the actuarial 1- and 2-year local control rate was 90%. Conclusion: Our retrospective study indicated that SBRT for the treatment of adrenal metastases represents a safe and effective option with a control rate of 90% at 2 years.

    Full Text Available We present a case of feminizing adrenal carcinoma with severe elevation in serum estradiol and otherwise unexplained congestive heart failure with ventricular arrhythmia and review the literature on feminizing adrenal tumors and the potential relationship between estrogen and cardiac problems. A 54-year-old man presented with congestive heart failure and ventricular arrhythmia. Imaging revealed a large adrenal mass. Hormonal evaluation revealed a very high serum level of estradiol, elevated DHEA-sulfate and androstenedione, and lack of cortisol suppression on a low-dose overnight dexamethasone suppression test. The patient underwent a left adrenalectomy with subsequent normalization of serum estradiol. Surgical pathology examination established adrenocortical carcinoma MacFarlane stage II. Upon 15-month followup, the patient continued to have a normal serum estradiol level, his cardiac function was significantly improved, and he had no further episodes of ventricular arrhythmia. To the best of our knowledge, the serum estradiol level that was detected in our case is the highest that has been reported. Further, we hypothesize that the very high serum concentration of estradiol in our case may have played a role in his cardiac presentation with congestive heart failure and arrhythmia, particularly as these problems resolved with normalization of his serum estradiol level.

    2016-09-01

    Adrenal gland diagnostics can pose significant challenges. In most academic and community practice settings, adrenal gland resections are encountered less frequently than other endocrine or genitourinary specimens, leading to less familiarity with evolving classifications and criteria. The unique dichotomy between cortical and medullary lesions reflects the developmental evolution of these functionally independent components. Adrenal cortical lesions at resection include hyperplasia, adenoma, and carcinoma, with some cases straddling the boundary between these distinct clinical classifications. The lack of immunohistochemical or molecular markers to definitively categorize these intermediate lesions enhances the diagnostic challenge. In addition, modified terminology for oncocytic and myxoid cortical lesions has been proposed. Medullary lesions are somewhat easier to categorize; however, the prediction of aggressive behavior in pheochromocytomas remains a challenge due to a lack of reliable prognostic biomarkers. Recent work by the Cancer Genome Atlas Project and other research groups has identified a limited subset of molecular and signaling pathway alterations in these 2 major neoplastic categories. Ongoing research to better define prognostic and predictive biomarkers in cortical and medullary lesions has the potential to enhance both pathologic diagnosis and patient therapy. PMID:27438375

    It has been suggested that the timing of pollination in Ephedra foeminea coincides with the full moon in July. The implication is that the plant can detect the full moon through light or gravity and that this trait is an evolutionary adaptation that aids the navigation by pollinating insects. Here we show that there are insufficient data to make such a claim, and we predict that pollinations of E. foeminea do not in general coincide with the full moon.

    Purpose The percentage of children who are symptomatic has been shown to increase with the number of signs of convergence insufficiency (CI). Our goal was to investigate whether there is a relationship between the severity of the clinical signs of CI and symptom level reported in children with 3-sign symptomatic CI. Methods The Convergence Insufficiency Treatment Trial (CITT) enrolled 221 children with symptomatic CI from ages 9 to 17 years. Inclusion criteria included the following three signs of CI: (1) exophoria at near at least 4Δ greater than at distance, (2) insufficient positive fusional vergence (PFV) at near, and (3) a receded near point of convergence (NPC) of ≥ 6cm break. The relationships between the severity of each sign of CI (mild, moderate and severe) and the level of symptoms as measured by the Convergence Insufficiency Symptom Survey (CISS) at baseline were evaluated. Results Mean CISS scores were not significantly different between mild, moderate or severe exophoria (p=0.60), PFV blur (p=0.99), Sheard's criterion (p=0.89) or NPC break (p=0.84). There was also no difference in the frequency of subjects scoring at mild, moderate or severe levels on the CISS and the severity of each sign of CI. Correlations between individual clinical signs and the CISS score were very low and not statistically significant. Conclusions Among symptomatic children with a CISS score ≥ 16 and three clinical signs of CI, there is no further association between the severity of the clinical signs and their level of symptoms.

    Full Text Available Background: Vitamin D plays an important role in regulating various homeostatic mechanisms and has yet untapped potential in cancer prevention and prognosis. Only a few studies have been done worldwide in relating the Vitamin D levels in pediatric cancer patients to the general population but none so far in an Indian setting to the best of our knowledge. Objective: To compare the Vitamin D levels in a group of children with cancer to that of the general pediatric population and to note differences in the prevalence of Vitamin D insufficiency and make inferences arising from demographic and therapeutic variations. Materials and Methods: Vitamin D levels were found by immuno-chemilumino-metric assay in 102 children (51 cases and 51 controls over a 6 months period. Results: In comparing the Vitamin D levels of children with cancer and controls from a healthy population we found an increased incidence of Vitamin D insufficiency in cancer children (80.39% when compared to controls (50.98% and a much lower mean Vitamin D value in cancer children (22.8 ng/ml when compared to controls (33 ng/dl. It was also found that cancer children above 6 years had a greater chance for developing Vitamin D insufficiency (P = 0.038 as did children suffering from hematological malignancies (P = 0.025. Conclusion: Our study showed an increased prevalence of Vitamin D insufficiency in children with cancer and hence we suggest routine measurement of Vitamin D levels in children with cancer and subsequent supplementation.

    Complications from a prolonged nasogastric tube intubation, though seldom reported, are well described. Herein we describe the first two reported cases of velopharyngeal insufficiency secondary to velopharyngeal scarring and immobility from repetitive nasogastric tube insertions and prolonged use. Differing only in location, the proposed pathophysiologic mechanism of injury is identical to that of the nasogastric tube syndrome, a rare and serious, well described entity consisting of bilateral vocal fold paralysis due to pressure-induced ulceration of the posterior cricoarytenoid musculature.

    2006-01-01

    Objective: To investigate the optimal time and procedure of surgical treatment of traumatic tricuspid insufficiency.Methods: From May 1984 to September 2004, eight patients underwent operation for traumatic tricuspid valve insufficiency. All patients, male, aged from 7 to 67 years [median: 38 years, mean: (38.5±18.1) years]. The intervals between trauma and operation ranged from 1 month to 20 years [ median: 19 months, mean: ( 52.5±80.3 ) months) ]. In seven patients, tricuspid insufficiency was attributed to blunt chest trauma including vehicle accident in three patients and the other patient is a stab wound. Diagnosis was confirmed by echocardiography. Pre-operative cardiac functions in patients were classified as New York Heart Association (NYHA) classes Ⅱ-Ⅳ.During operation, the anterior leaflet of the tricuspid valve was completely or partially flailed as a result of chordal rupture in all patients. Chordal rupture of septal leaflet was found in one patient. Anterior leaflet was perforated in two patients. Septal leaflet was retracted and adherent to ventricular septum in two patients. Valve repair was intended for all patients. Finally, valve repair was performed successfully in 3 patients and tricuspid replacement was performed in 5 patients.Results: No early or late death occurred. With a follow-up through clinical manifestation and echocardiography for 7-129 months [ median: 39 months, mean: (53.4 ± 42.8) months ], all patients were classified as NYHA class I, without any changes.Conclusions: The satisfactory treatment of traumatic tricuspid insufficiency can be obtained by surgical treatment. Earlier surgery may increase the feasibility of tricuspid valve repair and prevent the deterioration of right ventricular function.

  18. Impact of placental insufficiency on fetal skeletal muscle growth.

    2016-11-01

    Intrauterine growth restriction (IUGR) caused by placental insufficiency is one of the most common and complex problems in perinatology, with no known cure. In pregnancies affected by placental insufficiency, a poorly functioning placenta restricts nutrient supply to the fetus and prevents normal fetal growth. Among other significant deficits in organ development, the IUGR fetus characteristically has less lean body and skeletal muscle mass than their appropriately-grown counterparts. Reduced skeletal muscle growth is not fully compensated after birth, as individuals who were born small for gestational age (SGA) from IUGR have persistent reductions in muscle mass and strength into adulthood. The consequences of restricted muscle growth and accelerated postnatal "catch-up" growth in the form of adiposity may contribute to the increased later life risk for visceral adiposity, peripheral insulin resistance, diabetes, and cardiovascular disease in individuals who were formerly IUGR. This review will discuss how an insufficient placenta results in impaired fetal skeletal muscle growth and how lifelong reductions in muscle mass might contribute to increased metabolic disease risk in this vulnerable population.

  20. FEQ for Standard OFDM Systems with Insufficient CP

    2004-01-01

    In Orthogonai frequency division multiplexing (OFDM) systems, when the length of the Cyclic prefix (CP) is shorter than the channel length, there exist Intersymbol interference (ISI) and Interchannel interference (ICI) and the one-tap frequency domain equalizer is not applicable any more. A Time-domain equalizer (TEQ) is usually used in the receiver to reduce the duration of the overall response of the transmission system, and therefore minimize the ISI and ICI. However, the optimum design of TEQ turns out to be a difficult task. In this paper, we propose a Frequency domain equalizer (FEQ) for standard OFDM systems with insufficient CP by employing the null side sub-carriers and CP redundancy. The equalizer has a sparse matrix structure and thus a low computational complexity. Theoretical anaiysis and simulation results indicate that it can efficiently remove ISI and ICI caused by insufficient CP and recover the transmitted data. Moreover, we derive the condition for the existence and uniqueness of FEQ, i.e., the combined length of CP and null subcarriers is not shorter than the channel order, which means that the insufficiency of CP in time domain can be compensated by the redundancy in frequency domain.

    These studies investigated the appearance and function of adrenal glands in rats with severe acute pancreatitis (SAP) and established a new histopathological score to evaluate adrenal histopathological changes. Severe acute pancreatitis relied on retrograde infusion of 5% sodium taurocholate into the bile-pancreatic duct. The damage of SAP was estimated by serum amylase, secretory phospholipase A2 and pancreatic histopathology. Light and electron microscopy of adrenal gland, and the levels of serum corticosterone were investigated. These results showed that the generally ascending trend of adrenal pathological score was inversely proportional to the generally descending trend of serum corticosterone levels, but parallel with the changes of pancreatic histopathology. Herein, the new adrenal histopathological score was effective in the evaluation of adrenal injury following SAP. It may indirectly reflect the variation of serum cortisol levels and the severity of pancreatitis to a certain extent.

    Full Text Available Primary mesenchymal neoplasms of the adrenal gland are extremely rare. The most common primary sarcoma is adrenal angiosarcoma. We report the case of a 51-year-old patient who presented with left flank pain. After ultrasound investigations, the patient underwent surgical removal of an adrenal tumor. The gross adrenal specimen showed extensive cystic changes with old hemorrhage and necrosis. Histologically, irregular branching vascular channels were seen intermixed with solid areas of epithelioid cells. Immunohistochemical staining of tumor cells was positive with antibodies to cytokeratin and CD31. After a 12 months follow-up, the patient is still well with no sign of a relapse. Because of the epithelioid appearance and frequent expression of epithelial immunohistochemical markers, primary epithelioid angiosarcoma of the adrenal gland can be confounded with adrenal carcinomatous metastases. We report our findings with a brief literature review and discussion of differential diagnosis. [J Interdiscipl Histopathol 2016; 4(3.000: 67-69

    Adrenal tumors are increasingly detected by widespread use of anatomical imaging such as CT, MRI, etc. For these adrenal tumors, differentiation between malignancy and benignancy is very important. In diagnostic assessment of adrenal tumor, {sup 18}F-FDG PET and PET-CT have been reported to have high diagnostic performance, especially, very excellent performance in evaluation of adrenal metastasis in the oncologic patient. In cases of adrenal incidentalomas, {sup 18}F-FDG PET or PET-CT is helpful if CT or chemical-shift MRI is inconclusive. {sup 18}F-FDG PET and PET-CT may be applied to the patients with MIBG-negative pheochromocytomas. In summary, {sup 18}F-FDG PET and PET-CT are expected to be effective diagnostic tools in the management of adrenal tumor.

    Full Text Available Abstract Introduction Adrenal pseudocysts are rare cystic masses that arise from the adrenal gland and which are usually non-functional and asymptomatic. Adrenal pseudocysts consist of a fibrous wall without an epithelial or endothelial lining. We report the case of a patient with a giant adrenal pseudocyst presenting with right hypochondralgia and high fever. Case presentation A 52-year-old Japanese man was admitted with right hypochondralgia and a chill. Abdominal computed tomography revealed a well-defined cystic mass measuring 19 cm which was located in the right adrenal region and the contents of which were not enhanced with contrast medium. Abdominal ultrasonography revealed a heterogeneously hypo-echoic lesion with a peripheral high-echoic rim. Serum hormonal levels were almost normal. Despite treatment with antibiotics, the high fever persisted. Based on these findings, we made a preoperative diagnosis of a right adrenal cyst with infection. However, the possibility of malignancy still remained. The patient underwent laparotomy and right adrenal cyst excision with partial hepatectomy in order to relieve the symptoms and to confirm an accurate diagnosis. Histological examination revealed an adrenal pseudocyst with infection. His condition improved soon after the operation. Conclusion We report a case of a giant adrenal pseudocyst with infection. Surgery is required for symptomatic cases in order to relieve the symptoms and in cases of uncertain diagnosis.

  12. Adipose Tissue and Adrenal Glands: Novel Pathophysiological Mechanisms and Clinical Applications

    Atil Y. Kargi

    2014-01-01

    Full Text Available Hormones produced by the adrenal glands and adipose tissues have important roles in normal physiology and are altered in many disease states. Obesity is associated with changes in adrenal function, including increase in adrenal medullary catecholamine output, alterations of the hypothalamic-pituitary-adrenal (HPA axis, elevations in circulating aldosterone together with changes in adipose tissue glucocorticoid metabolism, and enhanced adipocyte mineralocorticoid receptor activity. It is unknown whether these changes in adrenal endocrine function are in part responsible for the pathogenesis of obesity and related comorbidities or represent an adaptive response. In turn, adipose tissue hormones or “adipokines” have direct effects on the adrenal glands and interact with adrenal hormones at several levels. Here we review the emerging evidence supporting the existence of “cross talk” between the adrenal gland and adipose tissue, focusing on the relevance and roles of their respective hormones in health and disease states including obesity, metabolic syndrome, and primary disorders of the adrenals.

    The adrenal veins may present with a multitude of anatomical variants, which surgeons must be aware of when performing adrenalectomies. The adrenal veins originate during the formation of the prerenal inferior vena cava (IVC) and are remnants of the caudal portion of the subcardinal veins, cranial to the subcardinal sinus in the embryo. The many communications between the posterior cardinal, supracardinal, and subcardinal veins of the primordial venous system provide an explanation for the variable anatomy. Most commonly, one central vein drains each adrenal gland. The long left adrenal vein joins the inferior phrenic vein and drains into the left renal vein, while the short right adrenal vein drains immediately into the IVC. Multiple variations exist bilaterally and may pose the risk of surgical complications. Due to the potential for collaterals and accessory adrenal vessels, great caution must be taken during an adrenalectomy. Adrenal venous sampling, the gold standard in diagnosing primary hyperaldosteronism, also requires the clinician to have a thorough knowledge of the adrenal vein anatomy to avoid iatrogenic injury. The adrenal vein acts as an important conduit in portosystemic shunts, thus the nature of the anatomy and hypercoagulable states pose the risk of thrombosis.

    To evaluate whether single-phase dual-energy-CT-based attenuation measurements can reliably differentiate lipid-rich adrenal adenomas from malignant adrenal lesions. We retrospectively identified 51 patients with adrenal masses who had undergone contrast-enhanced dual-energy-CT (140/100 or 140/80 kVp). Virtual non-contrast and colour-coded iodine images were generated, allowing for measurement of pre- and post-contrast density on a single-phase acquisition. Adrenal adenoma was diagnosed if density on virtual non-contrast images was ≤10 HU. Clinical follow-up, true non-contrast CT, PET/CT, in- and opposed-phase MRI, and histopathology served as the standard of reference. Based on the standard of reference, 46/57 (80.7 %) adrenal masses were characterised as adenomas or other benign lesions; 9 malignant lesions were detected. Based on a cutoff value of 10 HU, virtual non-contrast images allowed for correct identification of adrenal adenomas in 33 of 46 (71 %), whereas 13/46 (28 %) adrenal adenomas were lipid poor with a density ≥10 HU. Based on the threshold of 10 HU on the virtual non-contrast images, the sensitivity, specificity, and accuracy for detection of benign adrenal lesions was 73 %, 100 %, and 81 % respectively. Virtual non-contrast images derived from dual-energy-CT allow for accurate characterisation of lipid-rich adrenal adenomas and can help to avoid additional follow-up imaging. (orig.)

  16. Aberrant expression of glucagon receptors in adrenal glands of a patient with Cushing's syndrome and ACTH-independent macronodular adrenal hyperplasia

    2010-06-01

    Full Text Available Adrenocorticotropin (ACTH independent bilateral macronodular adrenal hyperplasia (AIMAH is a rare cause of Cushing´s syndrome, characterized by bilateral adrenal lesions and excess cortisol production despite ACTH suppression. Cortisol synthesis is produced in response to abnormal activation of G-protein- coupled receptors, such as gastric inhibitory peptide, vasopressin, beta adrenergic agonists, LH/hCG and serotonin receptors. The aim of this study was to analyze the expression of glucagon receptors in adrenal glands from an AIMAH patient. A patient with ACTH-independent Cushing´s syndrome and bilateral macronodular adrenal hyperplasia was screened for altered activation of adrenal receptors by physiological (mixed meal and pharmacological (gonadotrophin releasing hormone, ACTH and glucagon tests. The results showed abnormally high levels of serum cortisol after stimulation with glucagon. Hypercortisolism was successfully managed with ketoconazole treatment. Interestingly, a 4-month treatment with a somatostatin analogue (octreotide was also able to reduce cortisol secretion. Finally, Cushing's syndrome was cured after bilateral adrenalectomy. Abnormal mRNA expression for glucagon receptor in the patient´s adrenal glands was observed by Real-Time PCR procedure. These results strongly suggest that the mechanism of AIMAH causing Cushing´s syndrome in this case involves the illicit activation of adrenal glucagon receptors. This is the first case reported of AIMAH associated with ectopic glucagon receptors.

    Lipoid congenital adrenal hyperplasia (Lipoid CAH) is the most severe form of the autosomal recessive disorder CAH. A general loss of the steroid biosynthetic activity caused by defects in the StAR gene manifests as life-threatening primary adrenal insufficiency. We report a case of Lipoid CAH caused by a so far not described homozygous deletion of the complete StAR gene and provide diagnostic results based on a GC-MS steroid metabolomics and molecular genetic analysis. The patient presented with postnatal hypoglycemia, vomiting, adynamia, increasing pigmentation and hyponatremia. The constellation of urinary steroid metabolites suggested Lipoid CAH and ruled out all other forms of CAH or defects of aldosterone biosynthesis. After treatment with sodium supplementation, hydrocortisone and fludrocortisone the child fully recovered. Molecular genetic analysis demonstrated a homozygous 12.1 kb deletion in the StAR gene locus. The breakpoints of the deletion are embedded into two typical genomic repetitive Alu Sx elements upstream and downstream of the gene leading to the loss of all exons and regulatory elements. We established deletion-specific and intact allele-specific PCR methods and determined the StAR gene status of all available family members over three generations. This analysis revealed that one of the siblings, who died a few weeks after birth, carried the same genetic defect. Since several Alu repeats at the StAR gene locus increase the probability of deletions, patients with typical symptoms of lipoid CAH lacking evidence for the presence of both StAR alleles should be analyzed carefully for this kind of disorder.

In addition to psychological and social morbidity, depression exacerbates adverse cardiac outcomes in CHD patients. Inflammation has been proposed as one of the mechanisms involved in the association between these two debilitating diseases. Therefore, the present study aimed to evaluate inflammatory responses as well as to investigate the pathophysiological mechanisms underlying the putative inflammatory activation in CHD patients with and without depression, by assessing the function of two important biological factors regulating inflammation, the hypothalamus-pituitary-adrenal (HPA) axis and the glucocorticoid receptor (GR). Eighty-three CHD patients with (n=28) and without (n=55) comorbid depression were recruited from primary care services in South London. Depression status was assessed by means of Clinical Interview Schedule Revised for diagnosis of depression, and Beck Depression Inventory for the presence of depressive symptoms. Serum C-reactive protein (CRP), plasma vascular endothelial growth factor (VEGF), and plasma and salivary cortisol were measured using commercially available ELISA kits. Gene expression of GR and interleukin-6 (IL-6) were conducted via qPCR. GR sensitivity was evaluated in vitro in isolated peripheral blood mononuclear cells using the dexamethasone inhibition of lipopolysaccharide-stimulated IL-6 levels. Serum levels of kynurenine pathway metabolites were measured using high performance liquid chromatography. Our results show that CHD patients with depression had higher levels of CRP, IL-6 gene expression, and VEGF compared with CHD non-depressed, as well as lower plasma and saliva cortisol levels. The CHD depressed group also exhibited a reduction in GR expression and sensitivity. Finally, tryptophan levels were significantly lower in patients with depression, who also showed an increased kynurenine/tryptophan ratio. In conclusion, CHD

    The results of treatment of 65 patients, suffering diffuse peritonitis, were analyzed. For the abdominal cavity sanation and intestinal decontamination the adopted selective bacteriophages (polyvalent pyobacteriophage, intesti-bacteriophage, and the coliproteus one) were applied. The abdominal cavity state was estimated while doing a programmed relaparotomy. Bacteriologic investigation of exudate, excreted along nasointestinal probe, and of peritoneal exudate was conducted. The intestinal motor-evacuation function restoration was estimated in accordance to data of ultrasonographic investigation. Application of the procedure proposed have promoted earlier restoration of intestinal motor and the barrier functions, and elimination of enteral insufficiency syndrome.

    Full Text Available Recent reports have emerged suggesting that multiple sclerosis (MS may be due to abnormal venous outflow from the central nervous system, termed Chronic Cerebrospinal Venous Insufficiency (CCSVI. These reports have generated strong interest and controversy over the prospect of a treatable cause of this chronic debilitating disease. This review aims to describe the proposed association between CCSVI and MS, summarize the current data, and discuss the role of endovascular therapy and the need for rigorous randomized clinical trials to evaluate this association and treatment.

    Full Text Available Context Morbid obesity is associated with various co-morbidities, including chronic venous insufficiency. Bariatric surgery is the only effective treatment for morbid obesity, but with potential risks and possible complications, including venous thromboembolism. Objective To determine the prevalence of clinical and ultrasonographic signs of chronic venous insufficiency in morbid obese patients in preparation for bariatric surgery and the incidence of post-operative venous thromboembolic disease. Methods Patients on work-up for bariatric surgery of Centro Terapêutico Especializado em Fígado (CETEFI and Pro-Gastro surgical teams of the Hospital Beneficência Portuguesa de São Paulo were included. The analysed data were pre-operative findings for venous insufficiency (CEAP - clinical, etiological, anatomical, physiopathologic - classification and venous ultrassonographic findings, type of surgery (open or laparoscopic, abdominal circumference, body mass index (BMI and post-operative ultrassonography search for venous insufficiency and deep venous thrombosis. Results Between March 2007 and December 2009, 95 patients candidates for bariatric surgery had clinical and duplex scan evaluation of the lower limbs venous system. Of the 95 patients, 53 were submitted to the surgical procedure. There was a predominance of women (77.9%, the average age was 38.5 years, average preoperative weight 124.6 kg and average BMI of 45.5 kg/m2. Regarding obesity, 16.8% were obese, and 83.1% were morbidly obese. In relation to the venous findings, 86.3% of the patients did fit CEAP classification less than 3 and 13.7% greater than or equal to 3. Among the post-operative complications, there were four cases of wound infection. Three patients developed post-operative distal venous thrombosis (7.5%, but no one had clinically manifested pulmonary embolism. Conclusion No relation between BMI, CEAP classification and venous ultrassonographic findings were found. Although

  4. Effects of Carbenoxolone on the Canine Pituitary-Adrenal Axis.

    Full Text Available Cushing's disease caused by pituitary corticotroph adenoma is a common endocrine disease in dogs. A characteristic biochemical feature of corticotroph adenomas is their relative resistance to suppressive negative feedback by glucocorticoids. The abnormal expression of 11beta-hydroxysteroid dehydrogenase (11HSD, which is a cortisol metabolic enzyme, is found in human and murine corticotroph adenomas. Our recent studies demonstrated that canine corticotroph adenomas also have abnormal expression of 11HSD. 11HSD has two isoforms in dogs, 11HSD type1 (HSD11B1, which converts cortisone into active cortisol, and 11HSD type2 (HSD11B2, which converts cortisol into inactive cortisone. It has been suggested that glucocorticoid resistance in corticotroph tumors is related to the overexpression of HSD11B2. Therefore it was our aim to investigate the effects of carbenoxolone (CBX, an 11HSD inhibitor, on the healthy dog's pituitary-adrenal axis. Dogs were administered 50 mg/kg of CBX twice each day for 15 days. During CBX administration, no adverse effects were observed in any dogs. The plasma adrenocorticotropic hormone (ACTH, and serum cortisol and cortisone concentrations were significantly lower at day 7 and 15 following corticotropin releasing hormone stimulation. After completion of CBX administration, the HSD11B1 mRNA expression was higher, and HSD11B2 mRNA expression was significantly lower in the pituitaries. Moreover, proopiomelanocortin mRNA expression was lower, and the ratio of ACTH-positive cells in the anterior pituitary was also significantly lower after CBX treatment. In adrenal glands treated with CBX, HSD11B1 and HSD11B2 mRNA expression were both lower compared to normal canine adrenal glands. The results of this study suggested that CBX inhibits ACTH secretion from pituitary due to altered 11HSD expressions, and is potentially useful for the treatment of canine Cushing's disease.

    Full Text Available In a patient with the clinical diagnosis of pheochromocytoma, the localization of the tumor is essential for planning treatment. Recently, we have performed I-123 metaiodobenzylguanidine (MIBG adrenal scintigraphy in a patient presenting with a history of paroxysmal hypertension. Scintigraphy accurately located an ectopic unilateral pheochromocytoma. The scintigraphic diagnosis was confirmed by surgery and a diagnosis of ectopic unilateral pheochromocytoma was made by histopathological examination. This case report illustrates the specific diagnosis of pheochromocytoma by I-123 MIBG scintigraphy which is especially useful when other diagnostic procedures are equivocal.

    A wide range of responses to sublethal levels of DDT exist, many of which are species specific and vary within each species depending upon age, sex, and physiological state. Sublethal levels of DDT do cause an increase in the adrenal cortical tissue of bobwhite quail, which may cause increased secretion of corticosteroids, and in turn affect reproduction. A delicate homeostatic balance exists within the avian endocrine system which may be disturbed by feeding sublethal levels of chlorinated hydrocarbon pesticides. This adverse effect on the endocrine system may cause subtle reproductive failures which go unnoticed until the population is greatly reduced.

    Acute stimulation of the hypothalamo-pituitary-adrenal (HPA) axis by selective serotonin reuptake inhibitors (SSRIs) is mediated by several postsynaptic 5-HT receptor subtypes. Activation of 5-HT(1A) and 5-HT(2A) receptors increases plasma corticosterone levels, and it is likely that these receptor...... that the two serotonin receptor subtypes affect the HPA axis via a central target. In conclusion, 5-HT(1A) and 5-HT(2A) receptors regulate corticotrophin-releasing hormone (CRH) neurons via distinct but strongly interacting pathways, probably converging on the same neurons in the hypothalamus....

    While assessing a potential role of adrenal glands in the production of the hitherto unidentified puberty-delaying pheromone of female mice, the urinary volatile profiles of normal and adrenalectomized animals were quantitatively compared. Six components, whose concentrations were depressed after adrenalectomy, were identified: 2-heptanone, trans-5-hepten-2-one, trans-4-hepten-2-one, n-pentyl acetate, cis-2-penten-1-yl acetate, and 2,5-dimethylpyrazine. When these laboratory-synthesized chemicals were added (in their natural concentrations) to either previously inactive urine from adrenalectomized females or plain water, the biological activity was fully restored.

    A prospective, randomized, double-blind trial recently demonstrated that treating patients with chronic renal insufficiency with benazepril significantly decelerates the rate of progression of the disease. We tested the hypothesis that preventative treatment with the angiotensin converting enzyme (ACE) inhibitor benazepril in patients with chronic renal insufficiency is cost-effective. A Markov chain model was used that considered regular treatment, hemodialysis, continuous ambulant peritoneal dialysis, transplantation, rejection and death. Clinical trial data were used to estimate the effects of benazepril treatment and to estimate the duration until renal replacement therapy was needed. Epidemiologic parameters were derived on the basis of Dutch registries of renal diseases, costs are estimated by updating former estimates, literature review and expert opinion. We found that preventative treatment with benazepril decreased the percentage of patients who died or developed end-stage renal disease. Total costs per patient are expected to decrease in three years with more than $4,000 US per patient. Extrapolated to ten years, the savings are estimated at $23,500 US per patient. Benazepril treatment is not only an effective treatment in patients with chronic renal failure. By increasing the years spent without dialysis, it is also a cost-effective treatment. PMID:9407447

    Full Text Available Chronic venous insufficiency (CVI leads to skin changes with dermal hemosiderin deposition. We studied the presence of hemosiderin in the urine to assess if this could be used as a biochemical marker for CVI. Hereby we present a case control study conducted in a tertiary care centre in South India. There were 100 cases with evidence of advanced CVI (the Clinical-Etiology-Anatomy-Pathophysiology classification: C5, C6 confirmed by duplex scanning. Controls were 50 patients with leg ulcers due to other etiologies. All patients were subjected to urinary hemosiderin testing. In all 100 patients with CVI (C5 and C6 disease axial venous reflux was confirmed by duplex ultrasound. Superficial venous reflux was noted in 71% of patients and deep venous reflux in 54.%. Primary venous insufficiency was the etiology in 81% of patients. Only 4/100 patients had detectable amounts of hemosiderin in the urine. Urine hemosiderin testing to determine presence or absence of CVI yielded the following values: positive predictive value-80%; negative predictive value-33%; sensitivity-4% and specificity-98%. The test could not be recommended as a marker of CVI. In Indian patients urinary hemosiderin is not a useful screening test in CVI.

  12. Adolescent Premature Ovarian Insufficiency Following Human Papillomavirus Vaccination

    Deirdre Therese Little MBBS, DRANZCOG, FACRRM

    2014-10-01

    Full Text Available Three young women who developed premature ovarian insufficiency following quadrivalent human papillomavirus (HPV vaccination presented to a general practitioner in rural New South Wales, Australia. The unrelated girls were aged 16, 16, and 18 years at diagnosis. Each had received HPV vaccinations prior to the onset of ovarian decline. Vaccinations had been administered in different regions of the state of New South Wales and the 3 girls lived in different towns in that state. Each had been prescribed the oral contraceptive pill to treat menstrual cycle abnormalities prior to investigation and diagnosis. Vaccine research does not present an ovary histology report of tested rats but does present a testicular histology report. Enduring ovarian capacity and duration of function following vaccination is unresearched in preclinical studies, clinical and postlicensure studies. Postmarketing surveillance does not accurately represent diagnoses in adverse event notifications and can neither represent unnotified cases nor compare incident statistics with vaccine course administration rates. The potential significance of a case series of adolescents with idiopathic premature ovarian insufficiency following HPV vaccination presenting to a general practice warrants further research. Preservation of reproductive health is a primary concern in the recipient target group. Since this group includes all prepubertal and pubertal young women, demonstration of ongoing, uncompromised safety for the ovary is urgently required. This matter needs to be resolved for the purposes of population health and public vaccine confidence.

This treatment is safe and has few side effects. Data demonstrate efficacy in reducing steatorrhea and fat malabsorption. Effective therapy has been limited by the ability to replicate the physiologic process of enzyme delivery to the appropriate site, in general the duodenum, at the appropriate time. The challenges include enzyme destruction in the stomach, lack of adequate mixing with the chyme in the duodenum, and failing to deliver and activate at the appropriate time. Treatment is begun when clinically significant malabsorption occurs resulting in steatorrhea and weight loss. Treatment failure is addressed in a sequential fashion. Current research is aimed at studying new enzymes and delivery systems to improve the efficiency of action in the duodenum along with developing better means to monitor therapy.Keywords: exocrine pancreatic insufficiency, chronic pancreatitis, cystic fibrosis, pancreatic enzyme replacement therapy, lipase, lipids

  14. Are children given insufficient pain-relieving medication postoperatively?

    1998-01-01

    The literature often suggests and assumes that children are under-medicated postoperatively. A review of the literature leads to the conclusion that only a few studies answer the question of whether children's pain is relieved insufficiently. The lack of consensus on expected pain intensity after surgery and caution about prescribing analgesics could explain why analgesics are often prescribed on a pro re nata (prn) basis. Prescription on a prn basis, in fact, means that the nurse makes the decision whether or not an analgesic should be administered. Some studies suggest, however, that nurses under-medicate children and that postoperative pain is relieved insufficiently. In some situations, nurses under-estimate the child's pain, while in others, nurses' attitudes, beliefs and knowledge regarding pain relief strategies play an important role. On the basis of this review of the literature standard prescription of pain medication instead of prn is recommended. Furthermore, research on the incidence and prevalence of pain in children and on the effectiveness of analgesic administration postoperatively is warranted. PMID:9515606

    Lacroix A.

    2000-01-01

    Full Text Available Recent studies from several groups have indicated that abnormal or ectopic expression and function of adrenal receptors for various hormones may regulate cortisol production in ACTH-independent hypercortisolism. Gastric inhibitory polypeptide (GIP-dependent Cushing's syndrome has been described in patients with either unilateral adenoma or bilateral macronodular adrenal hyperplasia; this syndrome results from the large adrenal overexpression of the GIP receptor without any activating mutation. We have conducted a systematic in vivo evaluation of patients with adrenal Cushing's syndrome in order to identify the presence of abnormal hormone receptors. In macronodular adrenal hyperplasia, we have identified, in addition to GIP-dependent Cushing's syndrome, other patients in whom cortisol production was regulated abnormally by vasopressin, ß-adrenergic receptor agonists, hCG/LH, or serotonin 5HT-4 receptor agonists. In patients with unilateral adrenal adenoma, the abnormal expression or function of GIP or vasopressin receptor has been found, but the presence of ectopic or abnormal hormone receptors appears to be less prevalent than in macronodular adrenal hyperplasia. The identification of the presence of an abnormal adrenal receptor offers the possibility of a new pharmacological approach to control hypercortisolism by suppressing the endogenous ligands or by using specific antagonists for the abnormal receptors.

    Full Text Available There is ample historical verification of 46,XX congenital adrenal hyperplasia (CAH patients being born with essentially male genitaliawhile outcome information is scant. Prior to glucocorticoid therapy, most patients died very young from adrenal insufficiency. Most available reports from laterchildhood, contain little information concerning sexual identity. Reports on older individuals lack adequate information about sexual identity and quality of life. The difficulty in assessing the relative impact of multiple dynamic environmental factors on the development of sexual identity, self- and body esteem and overall adjustment to life is clear. Nevertheless, it remains unclear whether those infants whose masculine genitalia at birth resulted in an initial male assignment would have enjoyed a better adult outcome had they been allowed to remain male rather than the female reassignment that most received. Further, one could ask whether a male sex of rearing should be considered in 46,XX CAH infants with male external genitalia. After reviewing available literature, we conclude that because those extremely virlized 46,XX CAH patients who were reared male with healthy social support demonstrated satisfactory levels of social and sexual function as adults a male sex assignment should be considered in these types of infants when social and cultural environment are supportive.

    Kaposi sarcoma (KS), a vascular tumor caused by infection with human herpesvirus 8 (HHV8), is a systemic disease that can present with cutaneous lesions with or without visceral involvement. Very few cases of KS, most of which were associated with AIDS, have been reported in the adrenal gland. Anaplastic transformation of KS is a rare clinical presentation known as an aggressive disease with local recurrence and metastatic potential. We report here a 47-year-old HIV negative male presented with extra-adrenal symptoms and had an incidentally detected anaplastic adrenal KS exhibited aggressive clinical course. To the best of our knowledge, this is the first case of anaplastic primary adrenal KS without mucocutaneous involvement but subsequently developed other side adrenal metastases in an HIV negative patient.

    An 8 year old male castrated Russian Blue cat with polyuria, polydipsia, polyphagia, abdominal enlargement, unkempt and easily epilated hair coat and abdominal alopecia is described. As a first step diabetes mellitus was diagnosed. Further work-up by ultrasonography revealed severe bilateral enlargement of the adrenal glands. Hypercortisolism was suspected and therefore ACTH stimulation test and dexamethasone suppression test were performed. In all samples cortisol concentrations were below the detection limit of the assay used. Various precursor hormones were measured and high progesterone concentrations were found. Histologically, the adrenal masses were characterised as bilateral adrenal carcinomas of the adrenal cortex. The case report demonstrates that adrenal gland tumors are also capable to secrete sex hormones instead of cortisol. Clinical signs of hyperprogesteronism are identical to those of hypercortisolism.

    Adrenal necrosis, a rare life threatening complication of antiphospholipid syndrome, is difficult to diagnose during pregnancy. We report the case of a 33-year-old woman with bilateral adrenal necrosis which started during the third trimester of her second pregnancy. Antiphospholipid syndrome had been diagnosed few years ago, after a thrombotic event. The pregnancy was uneventful until 36 weeks plus five days, when the patient was admitted for bilateral back ache, initially considered as uterine contractions. Labour was induced because pain persisted and was associated with major thrombocytopenia. A healthy infant was delivered vaginally on the second day, adrenal failure was diagnosed based on intense asthenia, persistent severe lumbar pain, low blood sodium and cortisol. Bilateral adrenal oedema was documented by CT scan and MRI. Symptoms resolved following administration of hydrocortisone and fludrocortisone. This case illustrates the difficulty to diagnose adrenal necrosis in the third trimester of pregnancy.

    Beckwith-Wiedemann syndrome(BWS) is an overgrowth syndrome associated with increased risk to develop malignancies including adrenocortical carcinoma. Ovarian thecal metaplasia of the adrenal gland is a rare tumorlike mesenchymal lesion in BWS patients that lacks detailed radiological description. We report a 17-yearold female patient with BWS, associated with bilateral Wilms tumor, hepatic hemangiomatosis, pancreatic neuroendocrine tumor, and a phyllodes tumor of the right breast. Surveillance abdominal ultrasound identified a right adrenal mass that was further characterized by computed tomography and magnetic resonance imaging. Radiologically, this mass displayed features that overlap with adrenocortical carcinoma and pheochromocytoma but after pathological examination this proved to be an ovarian thecal metaplasia of the adrenal gland. Adrenal masses in BWS should raise the suspicion for adrenocortical carcinoma though other adrenal tumors including ovarian thecal metaplasia can be seen in these patients.

    Increased activity of the sympathetic system is an important feature contributing to the pathogenesis and progression of chronic heart failure. While the mechanisms and consequences of enhanced norepinephrine release from sympathetic nerves have been intensely studied, the role of the adrenal gland in the development of cardiac hypertrophy and progression of heart failure is less well known. Thus, the aim of the present study was to determine the effect of chronic cardiac pressure overload in mice on adrenal medulla structure and function. Cardiac hypertrophy was induced in wild-type mice by transverse aortic constriction (TAC) for 8 weeks. After TAC, the degree of cardiac hypertrophy correlated significantly with adrenal weight and adrenal catecholamine storage. In the medulla, TAC caused an increase in chromaffin cell size but did not result in chromaffin cell proliferation. Ablation of chromaffin α(2C)-adrenoceptors did not affect adrenal weight or epinephrine synthesis. However, unilateral denervation of the adrenal gland completely prevented adrenal hypertrophy and increased catecholamine synthesis. Transcriptome analysis of microdissected adrenal medulla identified 483 up- and 231 downregulated, well-annotated genes after TAC. Among these genes, G protein-coupled receptor kinases 2 (Grk2) and 6 and phenylethanolamine N-methyltransferase (Pnmt) were significantly upregulated by TAC. In vitro, acetylcholine-induced Pnmt and Grk2 expression as well as enhanced epinephrine content was prevented by inhibition of nicotinic acetylcholine receptors and Ca(2+)/calmodulin-dependent signaling. Thus, activation of preganglionic sympathetic nerves innervating the adrenal medulla plays an essential role in inducing adrenal hypertrophy, enhanced catecholamine synthesis and induction of Grk2 expression after cardiac pressure overload.

    Congenital adrenal hyperplasia (CAH) is a family of autosomal recessive disorders caused by mutations in genes encoding the enzymes involved in one of the 5 steps of adrenal steroid synthesis or the electron donor P450 oxidoreductase (POR) enzyme. Steroid 21-hydroxylase deficiency (21-OHD), the principal focus of this review, accounts for about 90-95% of all CAH cases, and its biochemical and clinical severity depends on the underlying CYP21A2 gene disruption. Molecular genetic advancements have been achieved in recent years, and the aim of this review is to attempt to highlight its contribution to the comprehension and management of the disease. When possible, we will try to achieve this goal also by providing some results from our personal experience regarding: some aspects of CYP21A2 gene analysis, with basic genotype/phenotype relationships; its crucial role in both genetic counselling and in prenatal diagnosis and treatment in families at risk for 21-OHD; its help in the comprehension of the severity of the disease in patients diagnosed by neonatal screening and possibly treated before an evident salt-loss crisis or before performing adequate blood sampling; its usefulness in the definition of post ACTH 17-hydroxyprogesterone values, discriminating between non-classic, heterozygote and normal subjects; and finally the contribution of genes other than CYP21A2 whose function or dysfunction could influence 21-hydroxylase activity and modify the presentation or management of the disease.

  10. Evaluation of cough in dogs with mitral valve insufficiency

    International Nuclear Information System (INIS)

    Distinguishing between respiratory and cardiac causes of coughing in dogs is critical to successful treatment. Such a distinction is especially important in older, small-breed dogs, which often experience both chronic respiratory disease and mitral valve insufficiency. Cough most commonly results from upper airway disease, tracheobronchial disease, pulmonary fibrosis, pulmonary neoplasia, pneumonia, and cardiac disease. Using historical and physical findings in conjunction with routinely available ancillary diagnostic procedures, the cause of cough can usually be determined and often effectively treated. Special diagnostic tests routinely available in general practice include conventional thoracic radiographs supplemented by expiratory lateral thoracic and inspiratory lateral cervical views to evaluate airway stability, electrocardiography, transtracheal aspiration with culture and sensitivity as well as cytologic evaluation, serology, specialized fecal examinations, and fine-needle aspiration of the lung

    Ugo Foscolo, was an Italian poet whose works rank among the masterpieces of Italian literature. Talented and well educated in philosophy, classics, and Italian literature, Foscolo gave literary expression to his ideological aspirations and to the numerous amorous experiences in odes, sonnets, plays, poems and an epistolary novel. Concurrent with his rich literary output, Foscolo's correspondence represents a unique perspective from which to monitor his literary and political views and investigate aspects of his everyday life. Among other interesting information, one can find elements of Foscolo's medical history which is generally unknown. Based on his testimonies we suggest that he suffered of longstanding bladder outlet obstruction presumably due to urethral stricture. In the present article we investigate the possibility that chronic bladder outlet obstruction and the consequent renal insufficiency was attributed to the death of Ugo Foscolo. PMID:26885466

    Surgical management of first ray insufficiency in HAV or hallux limitus is crucial to long-term success. Although technically demanding, the Lapidus fusion serves to address the deformity at its apex and restores normal weight bearing to the foot. This arthrodesis offers predictable, durable results in addressing various first ray deformities and occupies an important place in the foot and ankle surgeon's armamentarium. The authors' technique is described herein for the interest of and evaluation by surgeons performing this procedure. As clinicians recognize the importance of addressing proximal components of the HAV deformity, the Lapidus and other procedures will likely see increased use in the surgical management of first ray deformities.

    We report the case of a 73-year-old man with massive swelling of the lower extremities, with a chronic and rather uncommon form of stasis dermatitis - stasis papillomatosis. The patient was also diagnosed with severe heart failure, including dilated cardiomyopathy, hypothyroidism that required a substantial dose of exogenous tyrosine, microcytic and megaloblastic anemia, iron deficiency, and type 2 diabetes. The cause of stasis dermatitis lesions is not completely understood. It may be caused by the allergic reaction to some epidermal protein antigen formation or chronic damage to the dermal-epidermal barrier that makes the skin more sensitive to irritants or trauma. It has, however, been suggested that the term stasis dermatitis should be used to refer only to cases caused by chronic venous insufficiency, which belongs to a group of lifestyle diseases and affects both women and men more and more frequently.

    IgA Nephropathy leads young people to dialysis more often than other glomerular diseases, because often diagnosis and therapy are made late. Nephrologists waive to treat IgAN pts with chronic renal insufficiency, believing that treatment may not be effective and safe. Moreover, studies in IgAN pts with reduced renal function are lacking. Small studies seem to indicate a possible utility of RAS blockers and corticosteroids in these patients. Recently, VALIGA study showed that corticosteroids and immunosuppressants were more frequently used in pts with eGFR 30 ml/min (60 vs. 44 %, respectively; p = 0.004). The goal of treating IgAN pts is to obtain a time-average proteinuria 1 g/day a 6-month course of corticosteroids could be useful and safe. PMID:26743078

    Full Text Available Abstract Background Chronic cerebrospinal venous insufficiency (CCSVI is a vascular condition characterized by anomalies of the primary veins outside the skull that has been reported to be associated with MS. In the blinded Combined Transcranial (TCD and Extracranial Venous Doppler Evaluation (CTEVD study, we found that prevalence of CCSVI was significantly higher in multiple sclerosis (MS vs. healthy controls (HC (56.1% vs. 22.7%, p  The objective was to evaluate the clinical correlates of venous anomalies indicative of CCSVI in patients with MS. Methods The original study enrolled 499 subjects; 163 HC, 289 MS, 21 CIS and 26 subjects with other neurological disorders who underwent a clinical examination and a combined Doppler and TCD scan of the head and neck. This analysis was restricted to adult subjects with MS (RR-MS: n = 181, SP-MS: n = 80 and PP-MS: n = 12. Disability status was evaluated by using the Kurtzke Expanded Disability Status Scale (EDSS and MS severity scale (MSSS. Results Disability was not associated with the presence (≥2 venous hemodynamic criteria or the severity of CCSVI, as measured with venous hemodynamic insufficiency severity score (VHISS. However, the severity of CCSVI was associated with the increased brainstem functional EDSS sub-score (p = 0.002. In logistic regression analysis, progressive MS (SP-MS or PP-MS vs. non-progressive status (including RR-MS was associated with CCSVI diagnosis (p = 0.004, OR = 2.34, CI = 1.3–4.2. Conclusions The presence and severity of CCVSI in multiple sclerosis correlate with disease status but has no or very limited association with clinical disability.

  18. Atypical imaging features of adrenal gland lesions in children – report of three cases and review of literature

    International Nuclear Information System (INIS)

    The differential diagnosis of adrenal pathology depends on the child’s age and imaging findings. Three children without clinical symptoms of neoplasm, with an adrenal lesion discovered on diagnostic ultrasound imaging. Laboratory tests for neoplasm were negative. The final diagnosis was based on histopathological examinations after surgical resection. 1. The value of diagnostic imaging and laboratory tests in differential diagnosis of adrenal gland lesions is limited. 2. Malignant tumors of adrenal glands should be taken into account in children. 3. Surgical resection should be considered in diagnostic algorithm of adrenal gland masses. 4. The final diagnosis is always based on histopathological examination

    To compare adrenal gland volume in septic shock patients and control patients by using semi-automated volumetry. Adrenal gland volume and its inter-observer variability were measured with tomodensitometry using semi-automated software in 104 septic shock patients and in 40 control patients. The volumes of control and septic shock patients were compared and the relationship between volume and outcome in intensive care was studied. The mean total volume of both adrenal glands was 7.2 {+-} 2.0 cm{sup 3} in control subjects and 13.3 {+-} 4.7 cm{sup 3} for total adrenal gland volume in septic shock patients (p < 0.0001). Measurement reproducibility was excellent with a concordance correlation coefficient value of 0.87. The increasing adrenal gland volume was associated with a higher rate of survival in intensive care. The present study reports that with semi-automated software, adrenal gland volume can be measured easily and reproducibly. Adrenal gland volume was found to be nearly double in sepsis compared with control patients. The absence of increased volume during sepsis would appear to be associated with a higher rate of mortality and may represent a prognosis factor which may help the clinician to guide their strategy.

    Full Text Available Cytoplasmic inclusion bodies in adrenal medullary chromaffin cells have been described in various species including humans. These inclusions are believed to be related to certain infectious, toxic and neurodegenerative diseases. No reports concerning such adrenal inclusions have been described in bovines. Adrenal glands from twenty bovines were evaluated in a retrospective study. Seven of these exhibited inclusions - three cases of rabies, two cases of chronic suppurative bronchopneumonia, one case of chronic suppurative peritonitis, and one case of gangrenous mastitis. The inclusions were present in higher numbers especially in cases of rabies and also in one case of chronic suppurative bronchopneumonia. The inclusions were intracytoplasmic, eosinophilic, rounded, single or multiple, of various sizes, strongly stained by PAS and were present in higher numbers in the external layer of the adrenal medulla. The inclusions were negative when subjected to immunohistochemistry for detection of viral antigens in the cases of rabies. Although inclusion bodies were present in adrenal glands devoid of other histological alterations, they were more abundant in cases in which the adrenal gland had other alterations. The correlation between certain diseases and the development of inclusion bodies is not known, which highlights the importance of further studies on these inclusions in adrenal glands of bovines.
