    Adrenal insufficiency is a life-threatening condition that occurs secondary to impaired secretion of adrenal glucocorticoid and mineralocorticoid hormones. This condition can be caused by primary destruction or dysfunction of the adrenal glands or impairment of the hypothalamic-pituitary-adrenal axis. In children, the most common causes of primary adrenal insufficiency are impaired adrenal steroidogenesis (congenital adrenal hyperplasia) and adrenal destruction or dysfunction (autoimmune polyendocrine syndrome and adrenoleukodystrophy), whereas exogenous corticosteroid therapy withdrawal or poor adherence to scheduled corticosteroid dosing with long-standing treatment constitute the most common cause of acquired adrenal insufficiency. Although there are classic clinical signs (eg, fatigue, orthostatic hypotension, hyperpigmentation, hyponatremia, hyperkalemia, and hypoglycemia) of adrenal insufficiency, its early clinical presentation is most commonly vague and undefined, requiring a high index of suspicion. The relevance of early identification of adrenal insufficiency is to avoid the potential lethal outcome secondary to severe cardiovascular and hemodynamic insufficiency. The clinician must be aware of the need for increased corticosteroid dose supplementation during stress periods.

    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 defined by impaired secretion of adrenocortical hormones. It is classified upon the etiology in primary and secondary. Rapid recognition and therapy of adrenocortical crisis are critical to survival. Patients often have nonspecific symptoms: anorexia, vomiting, weakness, fatigue and lethargy. They are followed by hypotension, shock, hypoglicemia, hyponatremia and hyperkalemia. All patients with adrenal insufficiency require urgent fluid reposition, correction of hypoglycemia and glucocorticoid replacement, in order to avoid serious consequences of adrenal crisis. After initial crisis treatment, maintenance dose of corticoids should be indicated. Mineralocorticoids replacement, if necessary, should also be initiated.

    Iatrogenic adrenal insufficiency is a potential harmful side effect of treatment with corticosteroids. It manifests itself when an insufficient cortisol response to biological stress leads to an Addisonian crisis: a life-threatening situation. We describe a case of a patient who developed an Addisonian crisis after inappropriate discontinuation of budesonide (a topical steroid used in Crohn's disease) treatment. Iatrogenic adrenal insufficiency due to budesonide use has been rarely reported. Prescribers should be aware of the resulting risk for an Addisonian crisis.

    A 74 year old women presented with lethargy and weight loss and was found to have profound adrenal insufficiency and bilateral adrenal mass lesions. Histological examination revealed non-Hodgkin's lymphoma. There was no evidence of lymphoma outside the adrenal glands. Isolated bilateral adrenal masses may rarely be due to primary adrenal non-Hodgkin's lymphoma, which is often associated with adrenal insufficiency.

    Eight patients admitted to a University hospital with acute surgical problems and related adrenal insufficiency were reviewed and three are presented in detail. Surgical stress and continued sepsis played major roles in the lack of responsiveness to usual modes of therapy until the adrenal insufficiency was corrected. The patients fell into three major clinical categories of adrenal insufficiency. Chronic illness and sepsis are shown to affect steroid production and metabolism, as well as adrenal responsiveness to ACTH. Pharmacologic amounts of steroids are often needed in patients with shock, gram negative sepsis and prolonged illnesses, even if normal or elevated serum cortisols are present. Therapeutic trials of cortisol administration are shown to be confusing when not accompanied by easily performed diagnostic tests of adrenal function. It is emphasized that a pretreatment serum cortisol should be obtained whenever possible. The evaluation of adrenal function is of lifelong importance to the patient. PMID:165792

    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 < 0.05). A correlation between salivary cortisol and basal plasma cortisol (r = 0.6, p < 0.0004) was observed. Finally, survival at 1 year (97%) and 3 years (91%) was significantly higher without RAI than those who 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.

    A 60-year-old woman was admitted with severe hyponatremia. Basal values of adrenocorticotropic hormone (ACTH), thyroid hormone and cortisol were normal on admission. Impairment of water diuresis was observed by water loading test. Initially, we diagnosed her condition as the syndrome of inappropriate secretion of antidiuretic hormone (SIADH). By provocation test, we finally confirmed that the hyponatremia was caused by hypothalamic adrenal insufficiency. The basal values of ACTH and cortisol might not be sufficient to exclude the possibility of adrenal insufficiency. Therefore, it is necessary to evaluate adrenal function by provocation test or to re-evaluate it after recovery from hyponatremia.

    Patient: Female, 6 Final Diagnosis: Allgrove syndrome Symptoms: Achalasiaadrenal insufficiency • alacrima Medication: — Clinical Procedure: — Specialty: Pediatrics and Neonatology Objective: Rare disease Background: Allgrove syndrome, or triple “A” syndrome (3A syndrome), is a rare autosomal recessive syndrome with variable phenotype, and an estimated prevalence of 1 per 1,000,000 individuals. Patients usually display the triad of achalasia, alacrima, and adrenocorticotropin (ACTH) insensitive adrenal insufficiency, though the presentation is inconsistent. Case Report: Here, the authors report a case of Allgrove syndrome in a pediatric patient with delayed diagnosis in order to raise awareness of this potentially fatal disease as a differential diagnosis of alacrima. Conclusions: The prevalence of Allgrove syndrome may be much higher as a result of underdiagnosis and missed diagnosis due to the variable presentation and sudden unexplained childhood death from adrenal crisis. The authors review the characteristic symptoms of Allgrove syndrome in relation to the case study in order to avoid missed or delayed diagnosis, potentially decreasing morbidity, and mortality in those affected by this disease.

    2014-01-01

    Introduction Stiff ears appear to be a warning sign for adrenal insufficiency. This remarkable and rare sign has not been described to present in adrenal insufficiency in the setting of critical care. Case presentation We present the case of a 68-year-old Caucasian male who underwent a thymoma resection and suffered from preoperative weight loss and lack of strength. The perioperative phase was characterised by hypotension and sputum stasis due to muscle weakness, which caused two readmissions to the intensive care unit. His physical examination showed two fully rigid auricles. In retrospect, our patient suffered from secondary adrenal insufficiency and hypogonadism. Conclusions The bilateral rigid auricles appeared to be a warning sign for adrenal insufficiency. This remarkable sign is easily checked, and should prompt a higher index of suspicion towards adrenal insufficiency and other hormonal deficiencies. PMID:25209544

    Adrenal insufficiency is an uncommon cause of hypercalcemia and not easily considered as an etiology of adrenal insufficiency in clinical practice, as not all cases of adrenal insufficiency manifest as hypercalcemia. We report a case of secondary adrenal insufficiency presenting as hypercalcemia and acute kidney injury in a 66-year-old female. The patient was admitted to the emergency department with general weakness and poor oral intake. Hypercalcemia (11.5 mg/dL) and moderate renal dysfunction (serum creatinine 4.9 mg/dL) were shown in her initial laboratory findings. Studies for malignancy and hyperparathyroidism showed negative results. Basal cortisol and adrenocorticotropic hormone levels and adrenocorticotropic hormone stimulation test confirmed the diagnosis of adrenal insufficiency. With the administration of oral hydrocortisone, hypercalcemia was dramatically resolved within 3 days. This case shows that adrenal insufficiency may manifest as hypercalcemia and acute kidney injury, which implicates that adrenal insufficiency should be considered a cause of hypercalcemia in clinical practice.

    Primary bone lymphoma and primary adrenal lymphoma are rare clinicopathological entities of non-Hodgkin's lymphoma (NHL). We present the first case of diffuse large B-cell lymphoma with the involvement of a single bone and both adrenal glands alone with adrenal insufficiency. As primary extranodal NHL may have other unusual extranodal lesions, which may present unexplained clinical findings, patients with primary extranodal NHL require careful systemic examination, even when lymphadenopathy is absent.

    Adrenocortical carcinomas are relatively rare, but they are considered to be highly aggressive malignant tumors. Sarcomatoid carcinomas represent an even more aggressive type. Bilateral malignant adrenal tumors are extraordinary rare, except for those that represent metastatic spread from a primary neoplasm. Here we report a case of a 69-year-old woman who presented symptoms that raised strong suspicions of adrenal insufficiency. Bilateral adrenal masses, identified in the imaging study, were responsible for the clinical manifestation and surgically resected. Surgical specimens of the bilateral adrenal tumors shared histological features compatible with sarcomatoid carcinoma. It was very difficult to confirm that the sarcomatoid carcinomas were derived from the cortex of the adrenal glands, but careful morphological observation and the panel of antibodies used for immunohistochemistry made the diagnosis possible. This is the first report of sarcomatoid carcinomas involving both adrenal glands. It should be emphasized that sarcomatoid carcinoma can arise bilaterally from even functionally impaired adrenal glands.

    2016-01-01

    Adrenal crisis is a potential life threatening complication. The common causes of adrenal crisis are infections, surgical stress and abrupt cessation of steroid medications. Endocrine causes like Graves’ disease with thyrotoxicosis is one of the less common causes of an adrenal crisis. We report a 42-year-old female who presented with recurrent episodes of adrenal crisis due to delayed diagnosis of thyrotoxicosis. She was initially treated with Carbimazole followed by Radio-iodine ablation and currently she is euthyroid. Her adrenal insufficiency was initially treated with hydrocortisone during the time of adrenal crisis followed by Prednisolone 5 mg once daily in the morning along with fludrocortisone 50 mcg once daily. This case highlights the need for high index of suspicion and less common causes like thyrotoxicosis should be ruled out in patients with adrenal crisis. PMID:27190873

    Addison's disease or primary adrenal insufficiency (PAI) is a rare manifestation of antiphospholipid syndrome (APS). PAI is the most common among the endocrinologic manifestations and can also rarely be the presenting symptom of APS. Venous thrombosis and/or adrenal hemorrhage are the leading cause of PAI in APS. Autoimmune adrenal failure is postulated to be another possible mechanism. We report a case of PAI in a 44-year-old lady preceding primary APS, probably autoimmune, without any evidence of adrenal hemorrhage or infarction. High index of clinical suspicion for PAI in APS is needed; conversely APS should be considered as a possible pathogenetic process in patients presenting with Addison's disease where the etiology is not obvious.

    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. PMID:23864857

  1. 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).

    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

    Background The chronic use of glucocorticoids (GC) suppresses function of the hypothalamic-pituitary-adrenal axis and often results in secondary adrenal insufficiency (AI). The present study aimed to determine the recovery rate of adrenal function in patients with secondary AI within 1 to 2 years and to assess the factors predictive of adrenal function recovery. Methods This was a retrospective observational study that enrolled patients diagnosed with GC-induced secondary AI between 2007 and 2013. AI was defined by peak serum cortisol levels <18 µg/dL during a standard-dose short synacthen test (SST). A follow-up SST was performed after 1 to 2 years, and responders were defined as those with adrenocorticotropic hormone (ACTH)-stimulated peak serum cortisol levels ≥18 µg/dL. Results Of the total 34 patients diagnosed with GC-induced secondary AI at first, 20 patients (58.8%) recovered normal adrenal function by the time of the follow-up SST (median follow-up period, 16.5 months). Although the baseline serum ACTH and cortisol levels at the first SST did not differ between responders and non-responders, the incremental cortisol response during the first SST was higher in responders than that of non-responders (7.88 vs. 3.56, P<0.01). Additionally, higher cortisol increments during the first SST were an independent predictive factor of the adrenal function recovery (odds ratio, 1.58; 95% confidence interval, 1.02 to 2.46; P<0.05). Conclusion In the present study, adrenal function recovery was achieved frequently in patients with GC-induced secondary AI within 1 to 2 years. Additionally, an incremental cortisol response at the first SST may be an important predictive factor of adrenal function recovery. PMID:26676337

    Although it is a rare entity, primary lymphoma of the adrenal gland should be considered in the differential diagnosis of bilateral nodular adrenal lesions, particularly when there is evidence of associated adrenal insufficiency. We describe the case of an 83-year-old woman admitted to the emergency department due to a month's history of asthenia, weight loss, anorexia and nausea. Abdominopelvic CT showed bilateral nodular lesions of adrenal glands and a stimulation test with tetracosactide was compatible with primary adrenal insufficiency. CT-guided biopsy of the left adrenal gland was performed, and histopathological results were consistent with diffuse large B-cell lymphoma. Positron emission tomography (18)F-fluorodeoxyglucose detected two intensely hypermetabolic lesions limited to both adrenal glands. Replacement therapy with hydrocortisone 15 mg/day and fludrocortisone 0.1 mg/day was promptly started and chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone was initiated after haematology-oncology consultation.

    Central diabetes insipidus (CDI) is an infrequent complication of neurosarcoidosis (NS). Its presentation may be masked by adrenal insufficiency (AI) and uncovered by subsequent steroid replacement. A 45-year-old woman with a history of NS presented 2 weeks after abrupt cessation of prednisone with nausea, vomiting, decreased oral intake and confusion. She was diagnosed with secondary AI and intravenous hydrocortisone was promptly begun. Over the next few days, however, the patient developed severe thirst and polyuria exceeding 6 L of urine per day, accompanied by hypernatraemia and hypo-osmolar urine. She was presumed to have CDI due to NS, and intranasal desmopressin was administered. This eventually normalised her urine output and serum sodium. The patient was discharged improved on intranasal desmopressin and oral prednisone. AI may mask the manifestation of CDI because low serum cortisol impairs renal-free water clearance. Steroid replacement reverses this process and unmasks an underlying CDI.

    A 51-year-old woman with Cushing's syndrome underwent unilateral adrenalectomy for left adrenal adenoma. After 7 years of prednisolone treatment (with some interruptions), followed by 4 years of total withdrawal from prednisolone treatment, she presented with hypotension, weight loss, general fatigue, nausea, hyponatremia and hypoglycemia. These clinical features together with a low response in the rapid adrenocorticotropic hormone test led to the diagnosis of acute adrenal insufficiency. Relatively low serum adrenocorticotropic hormone levels in the face of increased demand for cortisol during adrenal crisis suggested a disordered hypothalamic-pituitary function, indicating secondary adrenal insufficiency. This patient demonstrated the etiology of acute adrenal insufficiency long after unilateral adrenalectomy in association with subsequent glucocorticoid therapy. A reduction in the reserved secretory capacity of cortisol after prolonged prednisolone treatment was considered to have induced secondary adrenal insufficiency, even after 4 years of total withdrawal from prednisolone.

    Primary adrenal lymphoma is an extremely rare entity which constitutes less than 1% of extranodal lymphomas. Most cases present with bilateral adrenal masses and without extraadrenal involvement, which can lead to symptoms of adrenal insufficiency. The prognosis is usually poor and chemotherapy is the first-line treatment option. We report here on a 78-year-old man admitted to our Internal Medicine Department because of constitutional symptoms and high fever spikes. He was diagnosed with adrenal insufficiency and a CT-scan revealed bilateral adrenal masses of about 6 cm in diameter. A percutaneous biopsy was performed and the histological exam was consistent with diffuse large B cell lymphoma. A review of the literature of this unusual entity was also carried out. PMID:27170834

    The hypothalamic-pituitary-adrenal (HPA) axis is a classic neuroendocrine system. One of the best ways to understand the HPA axis is to appreciate its dynamics in the variety of diseases and syndromes that affect it. Excess glucocorticoid activity can be due to endogenous cortisol overproduction (spontaneous Cushing’s syndrome) or exogenous glucocorticoid therapy (iatrogenic Cushing’s syndrome). Endogenous Cushing’s syndrome can be subdivided into ACTH-dependent and ACTH-independent, the latter of which is usually due to autonomous adrenal overproduction. The former can be due to a pituitary corticotroph tumor (usually benign) or ectopic ACTH production from tumors outside the pituitary; both of these tumor types overexpress the proopiomelanocortin gene. The converse of Cushing’s syndrome is the lack of normal cortisol secretion and is usually due to adrenal destruction (primary adrenal insufficiency) or hypopituitarism (secondary adrenal insufficiency). Secondary adrenal insufficiency can also result from a rapid discontinuation of long-term, pharmacological glucocorticoid therapy because of HPA axis suppression and adrenal atrophy. Finally, mutations in the steroidogenic enzymes of the adrenal cortex can lead to congenital adrenal hyperplasia and an increase in precursor steroids, particularly androgens. When present in utero, this can lead to masculinization of a female fetus. An understanding of the dynamics of the HPA axis is necessary to master the diagnosis and differential diagnosis of pituitary-adrenal diseases. Furthermore, understanding the pathophysiology of the HPA axis gives great insight into its normal control. PMID:24715566

    Adrenal insufficiency is a potential complication of therapy with an inhaled corticosteroid (ICS). Although prior studies found the highest risk of adrenal insufficiency with fluticasone, a more potent ICS, these results might be explained by a channelling bias and concomitant exposure to oral corticosteroids. We re-examined the relationship between the use of ICSs and adrenal insufficiency by using a cohort of patients treated for respiratory conditions during 1990-2005, identified in the healthcare databases from the province of Quebec, Canada, with follow-up until 2007. A nested case-control analysis was performed within this cohort. Cases of adrenal insufficiency were matched with up to 10 controls. 392 cases were identified (incidence rate 1.1 per 10 000 person-years). Although the rate of adrenal insufficiency was not significantly higher among all current users of ICSs, patients receiving the highest dosages showed a greater risk (OR 1.84, 95% CI 1.16-2.90). Consistently, an increased risk was estimated for the highest tertile of ICS dose (OR 1.90, 95% CI 1.07-3.37) cumulated in the year before the event. ICS at high doses appear to be a significant independent risk factor for adrenal insufficiency. Physicians prescribing ICS at such dosages should be sensitive to the signs and symptoms of adrenal insufficiency in their patients.

Its vague presentation can cause missed or delayed treatment for adrenal insufficiency, resulting in a life-threatening adrenal crisis. Case Report: A 21-yr-old man presented with lethargy, hypotension, hyponatremia, hypoglycemia, and an elevated thyroid-stimulating hormone level. He was binge drinking the day before presentation. No significant response to initial treatment with levothyroxine and dextrose occurred. Diagnostic workup later revealed primary adrenal insufficiency. All initial symptoms completely resolved following treatment with hydrocortisone, fludrocortisone, and levothyroxine. Conclusion: Autoimmune polyglandular syndrome causes dysfunction of multiple endocrine organs such as the thyroid gland, adrenal gland, and pancreas. Initial diagnosis of APS is crucial and difficult because of its vague, acute presentation, which often involves hypothyroidism and adrenal insufficiency. Delayed treatment of adrenal insufficiency can result in a life-threatening adrenal crisis. A diagnostic workup for adrenal insufficiency should be performed in patients who do not respond to hypothyroidism treatment. PMID:27298818

    Congenital adrenal insufficiency is caused by specific genetic mutations. Early suspicion and definite diagnosis are crucial because the disease can precipitate a life-threatening hypovolemic shock without prompt treatment. This study was designed to understand the clinical manifestations including growth patterns and to find the usefulness of ACTH stimulation test. Sixteen patients with confirmed genotyping were subdivided into three groups according to the genetic study results: congenital adrenal hyperplasia due to 21-hydroxylase deficiency (CAH, n=11), congenital lipoid adrenal hyperplasia (n=3) and X-linked adrenal hypoplasia congenita (n=2). Bone age advancement was prominent in patients with CAH especially after 60 months of chronologic age (n=6, 67%). They were diagnosed in older ages in group with bone age advancement (P<0.05). Comorbid conditions such as obesity, mental retardation, and central precocious puberty were also prominent in this group. In conclusion, this study showed the importance of understanding the clinical symptoms as well as genetic analysis for early diagnosis and management of congenital adrenal insufficiency. ACTH stimulation test played an important role to support the diagnosis and serum 17-hydroxyprogesterone levels were significantly elevated in all of the CAH patients. The test will be important for monitoring growth and puberty during follow up of patients with congenital adrenal insufficiency.

    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. PMID:25431697

    Metastases of solid tumors to the pituitary gland are often asymptomatic or appereas as with diabetes insipid us. Pituitary metastases more commonly affect the posterior lobe and the infundibulum than the anterior lobe. The presentation with an acute adrenal insufficiency is a rare event. A 69-year-old men presented with vomiting, low blood pressure and hypoglycemia. Hormonal exploration confirmed a hypopituitarism. Appropriate therapy was initiated urgently. The hypothalamic-pituitary MRI showed a pituitary hypertrophy, a nodular thickening of the pituitary stalk. The chest X Rays revealed pulmonary opacity. Computed tomography scan of the chest showed a multiples tumors with mediastinal lymphadenopathy. Bronchoscopy and biopsy demonstrated a pulmonary adenocarcinoma. Hence we concluded to a lung cancer with multiple pituitary and adrenal gland metastases. This case emphasizes the need for an etiological investigation of acute adrenal insufficiency after treatment of acute phase. PMID:27200139

    Animals living in the near-shore marine environment are predisposed to contact with chemical contaminants through land- and ocean-based activities. The release of petroleum hydrocarbons into the marine environment is a stressor to this environment and its resident wildlife. The stress response to chemical threats is dependent on an intact hypothalamic-pituitary-adrenal axis, which also may be a target to the effects of these chemicals. Ranch mink (Mustela vison) were used as surrogates for sea otters (Enhydra lutris) to examine the development of adrenal hypertrophy after chronic, oral exposure to low concentrations of bunker C fuel oil. Animals were fed three different concentrations of fuel oil (48, 520, and 908 ppm) or mineral oil (control) for 60-62 days. At the end of the exposure, blood and fecal samples were collected and organs were weighed and examined microscopically. In all fuel oil groups, exposure resulted in adrenal hypertrophy, an adaptation suggestive of adrenal activation. However, concentrations of serum and fecal glucocorticoids and serum progesterone were not elevated over control values. Hematologic parameters and serum chemistries showed no changes consistent with increased adrenal activity. In addition, adrenal glands from animals fed the higher concentrations of fuel oil contained large numbers of heavily vacuolated cells. We conclude that petroleum hydrocarbons are inducing an adrenal insufficiency that leads to the adaptive enlargement of the gland. This would increase the susceptibility of fuel oil-exposed animals to the deleterious effects of other environmental stressors.

    Abstract Several recent population-based studies have demonstrated that patients with inflammatory bowel disease are likely to have other autoimmune diseases. Here we describe the first de novo arisen case of primary adrenal insufficiency in an adolescent female patient with Crohn disease (CD). A 17-year-old female diagnosed with stricturing colonic CD received the maintenance regimen of Remicade (infliximab) 5 mg/kg every 8 weeks following the standard induction regimen. She had an ileocecostomy due to acute small bowel obstruction at 1.5-year since the last infusion of Remicade. She was presented with skin hyperpigmentation of her face, neck, upper limbs, buccal mucosa and lips, which worsened when commenced on 6-mercaptopurine treatment for prophylaxis of postoperative recurrence. An increased adrenocorticotropic hormone (20.3 pmol/L, range 2–11) measurement was obtained. Radiography of the sella turcica region showed no signs of pituitary disease, or abnormality of bilateral adrenal cortex. Since serum aldosterone was below the reference range, more importantly, assessments for both antiadrenal antibodies and anti-21-hydroxylase antibodies were positive, she was then diagnosed as primary adrenal insufficiency. The symptoms improved after supplement of hydrocortisone. This case highlights a rare immune-mediated comorbidity in an adolescent patient with CD. Recognition of a new pattern of autoimmune endocrine comorbidity enables clinicians to be alert about the possibility of concurrence of primary adrenal insufficiency with CD. PMID:26061303

    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. PMID:27375907

    Context: Serum free cortisol (SFF) responses to cosyntropin simulation test (CST) may more accurately assess adrenal function than total cortisol (TF). Objective: The objective of the study was to evaluate the diagnostic utility of SFF responses during a 250-μg CST. Design: We recruited healthy volunteers (HV; n = 27), patients with primary and secondary adrenal insufficiency (n = 19 and n = 24, respectively), and subjects with Child-Pugh class A cirrhosis (CH; n = 15). Each received 250 μg cosyntropin with measurement of ACTH and corticosteroid binding globulin (CBG) at time 0 and TF and SFF at 0, 30, and 60 minutes. Salivary cortisol was measured at all time points in CH subjects. Results: Peak SFF and TF were significantly higher in HVs vs both AI groups (P < .05). Peak SFF and TF (6.8 μg/dL vs 2.2 μg/dL; [188 nmol/L vs 62 nmol/L]; P < .01) were significantly higher in the secondary adrenal insufficiency vs primary adrenal insufficiency patients. The optimal peak SFF criterion to identify adrenal insufficiency patients vs HV was 0.9 μg/dL (25 nmol/L) (sensitivity of 95%, specificity of 100%). Mean CBG and albumin levels were similar among all four groups. CH patients had a higher peak SFF than HV (2.4 vs 2.0 μg/dL; P = .02. In the CH patients, peak salivary cortisol levels correlated well with peak SFF (rs = 0.84, P = .005). CBG levels were similar among the groups. Conclusion: We provide normative data for SFF values in HV and AI during the CST. Normal CBG levels in mild cirrhosis did not affect the interpretation of the CST. PMID:26647150

    PubMed Central

    2015-01-01

    It is important to fast diagnosis and management of the pediatric patients of the endocrine metabolic emergencies because the signs and symptoms of these disorders are nonspecific. Delayed diagnosis and treatment may lead to serious consequences of the pediatric patients, for example, cerebral dysfunction leading to coma or death of the patients with hypoglycemia, hypocalcemia, adrenal insufficiency, or diabetic ketoacidosis. The index of suspicion of the endocrine metabolic emergencies should be preceded prior to the starting nonspecific treatment. Importantly, proper diagnosis depends on the collection of blood and urine specimen before nonspecific therapy (intravenous hydration, electrolytes, glucose or calcium injection). At the same time, the taking of precise history and searching for pathognomonic physical findings should be performed. This review was described for fast diagnosis and proper management of hypoglycemic emergencies, hypocalcemia, adrenal insufficiency, and metabolic acidosis including diabetic ketoacidosis.

    Primary adrenal insufficiency is life threatening and can present alone or in combination with other comorbidities. Here, we have described a primary adrenal insufficiency syndrome and steroid-resistant nephrotic syndrome caused by loss-of-function mutations in sphingosine-1-phosphate lyase (SGPL1). SGPL1 executes the final decisive step of the sphingolipid breakdown pathway, mediating the irreversible cleavage of the lipid-signaling molecule sphingosine-1-phosphate (S1P). Mutations in other upstream components of the pathway lead to harmful accumulation of lysosomal sphingolipid species, which are associated with a series of conditions known as the sphingolipidoses. In this work, we have identified 4 different homozygous mutations, c.665G>A (p.R222Q), c.1633_1635delTTC (p.F545del), c.261+1G>A (p.S65Rfs*6), and c.7dupA (p.S3Kfs*11), in 5 families with the condition. In total, 8 patients were investigated, some of whom also manifested other features, including ichthyosis, primary hypothyroidism, neurological symptoms, and cryptorchidism. Sgpl1-/- mice recapitulated the main characteristics of the human disease with abnormal adrenal and renal morphology. Sgpl1-/- mice displayed disrupted adrenocortical zonation and defective expression of steroidogenic enzymes as well as renal histology in keeping with a glomerular phenotype. In summary, we have identified SGPL1 mutations in humans that perhaps represent a distinct multisystemic disorder of sphingolipid metabolism.

    Context: Primary adrenal insufficiency (PAI) is a life-threatening condition that is often due to monogenic causes in children. Although congenital adrenal hyperplasia occurs commonly, several other important molecular causes have been reported, often with overlapping clinical and biochemical features. The relative prevalence of these conditions is not known, but making a specific diagnosis can have important implications for management. Objective: The objective of the study was to investigate the clinical and molecular genetic characteristics of a nationwide cohort of children with PAI of unknown etiology. Design: A structured questionnaire was used to evaluate clinical, biochemical, and imaging data. Genetic analysis was performed using Haloplex capture and next-generation sequencing. Patients with congenital adrenal hyperplasia, adrenoleukodystrophy, autoimmune adrenal insufficiency, or obvious syndromic PAI were excluded. Setting: The study was conducted in 19 tertiary pediatric endocrinology clinics. Patients: Ninety-five children (48 females, aged 0–18 y, eight familial) with PAI of unknown etiology participated in the study. Results: A genetic diagnosis was obtained in 77 patients (81%). The range of etiologies was as follows: MC2R (n = 25), NR0B1 (n = 12), STAR (n = 11), CYP11A1 (n = 9), MRAP (n = 9), NNT (n = 7), ABCD1 (n = 2), NR5A1 (n = 1), and AAAS (n = 1). Recurrent mutations occurred in several genes, such as c.560delT in MC2R, p.R451W in CYP11A1, and c.IVS3ds+1delG in MRAP. Several important clinical and molecular insights emerged. Conclusion: This is the largest nationwide study of the molecular genetics of childhood PAI undertaken. Achieving a molecular diagnosis in more than 80% of children has important translational impact for counseling families, presymptomatic diagnosis, personalized treatment (eg, mineralocorticoid replacement), predicting comorbidities (eg, neurological, puberty/fertility), and targeting clinical genetic testing in the

    Corticotropin-releasing hormone (CRH)-deficient (KO) mice provide a unique system to define the role of CRH in regulation of the hypothalamic-pituitary-adrenal (HPA) axis. Despite several manifestations of chronic glucocorticoid insufficiency, basal pituitary proopiomelanocortin (POMC) mRNA, adrenocorticotrophic hormone (ACTH) peptide content within the pituitary, and plasma ACTH concentrations are not elevated in CRH KO mice. The normal POMC mRNA content in KO mice is dependent upon residual glucocorticoid secretion, as it increases in both KO and WT mice after adrenalectomy; this increase is reversed by glucocorticoid, but not aldosterone, replacement. However, the normal plasma levels of ACTH in CRH KO mice are not dependent upon residual glucocorticoid secretion, because, after adrenalectomy, these levels do not undergo the normal increase seen in KO mice despite the increase in POMC mRNA content. Administration of CRH restores ACTH secretion to its expected high level in adrenalectomized CRH KO mice. Thus, in adrenal insufficiency, loss of glucocorticoid feedback by itself can increase POMC gene expression in the pituitary; but CRH action is essential for this to result in increased secretion of ACTH. This may explain why, after withdrawal of chronic glucocorticoid treatment, reactivation of CRH secretion is a necessary prerequisite for recovery from suppression of the HPA axis.

    Numerous cases of Cushing syndrome have been reported as a result of the interaction between ritonavir (RTV) and exogenous steroid medications. Another complication that frequently occurs is secondary adrenal insufficiency, which can be profound and has not been well described. Here, we report 6 cases of adrenal suppression caused by RTV and exogenous steroids, all of which required corticosteroid replacement therapy and 2 of which were severe enough to require hospitalization. These cases add to the body of literature on the dangerous interaction between RTV and corticosteroids and highlight the risk of secondary adrenal suppression. We also review the literature on this complication and make a recommendation for managing and monitoring such cases.

    Background Adrenal insufficiency (AI) is a life-threatening disorder caused by the deficiency of adrenal steroid hormones. This retrospective cross-sectional study investigated the characteristics of patients with AI in Korea. Methods All consecutive patients with suspected AI who received care at a tertiary referral center in Korea in 2014 and underwent adrenocorticotropic hormone stimulation or insulin-tolerance testing were identified through a review of medical charts. Patients diagnosed with AI were enrolled. Their demographic, clinical, and treatment details were extracted. Results Of 771 patients with suspected AI, 183 (23.7%) received a definitive diagnosis. The most common reason for testing was the presence of suspicious AI-related symptoms (30.0%), followed by a history of steroid medications (23.5%). Their mean age was 66.7 years, and females predominated (67.8%). The most common symptoms were general weakness, anorexia, arthralgia, and fever. Approximately half (53.6%) had a history of steroid use. Hydrocortisone was the most common treatment (71.6%), with most patients taking a 30 mg dose (44.2%). The most common dose frequency was twice a day (78.6%). Fourteen patients were treated for adrenal crisis (n=10, 5.5%) or an intercurrent illness (n=4, 2.2%). Conclusion AI may have been caused by steroid medication use in many of the patients included in this study. The detection of AI can be improved by careful history-taking and being alert to the possibility that a patient has used steroids. PMID:28256113

    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.

    Objective Prednisolone is used as glucocorticoid replacement therapy for adrenal insufficiency (AI). Recent data indicate that its use in AI is associated with low bone mineral density. Data on risk factors for cardiovascular disease in patients with AI treated with prednisolone are scarce, despite this condition being the predominant cause of excess mortality. We aimed to address this question using real-world data from the European Adrenal Insufficiency Registry (EU-AIR). Design/methods EU-AIR, comprising of 19 centres across Germany, the Netherlands, Sweden and the UK, commenced enrolling patients with AI in August 2012. Patients receiving prednisolone (3–6 mg/day, n = 50) or hydrocortisone (15–30 mg/day, n = 909) were identified and grouped at a ratio of 1:3 (prednisolone:hydrocortisone) by matching for gender, age, duration and type of disease. Data from baseline and follow-up visits were analysed. Data from patients with congenital adrenal hyperplasia were excluded. Results Significantly higher mean ± s.d. total (6.3 ± 1.6 vs 5.4 ± 1.1 mmol/L; P = 0.003) and low-density lipoprotein (LDL) cholesterol levels (3.9 ± 1.4 vs 3.2 ± 1.0 mmol/L; P = 0.013) were identified in 47 patients on prednisolone vs 141 receiving hydrocortisone at baseline and at follow-up (P = 0.005 and P = 0.006, respectively). HbA1c, high-density lipoprotein and triglyceride levels, body mass index, systolic and diastolic blood pressure and waist circumference were not significantly different. Conclusions This is the first matched analysis of its kind. Significantly higher LDL levels in patients receiving prednisolone relative to hydrocortisone could predict a higher relative risk of cardiovascular disease in the former group. PMID:27864317

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. PMID:22695167

    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

    Several recent population-based studies have demonstrated that patients with inflammatory bowel disease are likely to have other autoimmune diseases. Here we describe the first de novo arisen case of primary adrenal insufficiency in an adolescent female patient with Crohn disease (CD). A 17-year-old female diagnosed with stricturing colonic CD received the maintenance regimen of Remicade (infliximab) 5 mg/kg every 8 weeks following the standard induction regimen. She had an ileocecostomy due to acute small bowel obstruction at 1.5-year since the last infusion of Remicade. She was presented with skin hyperpigmentation of her face, neck, upper limbs, buccal mucosa and lips, which worsened when commenced on 6-mercaptopurine treatment for prophylaxis of postoperative recurrence. An increased adrenocorticotropic hormone (20.3 pmol/L, range 2-11) measurement was obtained. Radiography of the sella turcica region showed no signs of pituitary disease, or abnormality of bilateral adrenal cortex. Since serum aldosterone was below the reference range, more importantly, assessments for both antiadrenal antibodies and anti-21-hydroxylase antibodies were positive, she was then diagnosed as primary adrenal insufficiency. The symptoms improved after supplement of hydrocortisone. This case highlights a rare immune-mediated comorbidity in an adolescent patient with CD. Recognition of a new pattern of autoimmune endocrine comorbidity enables clinicians to be alert about the possibility of concurrence of primary adrenal insufficiency with CD.

    A fatigued 8-year-old boy was found to have sideroblastic anaemia (haemoglobin 7.8 g/dL) which over time became transfusion dependent. Subtle neurological dysfunction, initially manifesting as mild spastic diplegia, was slowly progressive and ultimately led to wheelchair dependence. Elevated plasma lactate and urinary 3-methylglutaconate led to a muscle biopsy which confirmed partial complex IV deficiency. PCR in leucocytes and muscle was negative for mitochondrial DNA (mtDNA) deletions. Faltering growth prompted an insulin tolerance test which confirmed growth hormone sufficiency and adrenal insufficiency. Plasma renin was elevated and adrenal androgens were low, suggesting primary adrenal insufficiency. Glucocorticoid and mineralocorticoid replacement therapy was initiated. A renal tubular Fanconi syndrome and diabetes mellitus developed subsequently. Sideroblastic anaemia and primary adrenal insufficiency, both individually and collectively, are associated with mtDNA deletion; however, absence of the same does not exclude the possibility that sideroblastic anaemia and primary adrenal insufficiency are of mitochondrial origin.

    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

    Drug-induced liver injury (DILI) in a patient with multiple comorbidities is often challenging to diagnose because liver injury can be attributed to multiple disease processes. Delayed treatment of DILI could have fatal consequences and, therefore, understanding the features and risks of DILI is crucial. We report a unique case of a patient who was admitted for severe sepsis of unknown etiology. This patient was later found to have miliary tuberculosis (TB) with associated adrenal insufficiency, complicated by acute cholestatic liver injury. Liver injury fully improved after initiation of corticosteroid for the treatment of adrenal insufficiency. The most likely pathophysiology of acute liver injury was DILI, given the clinical course of liver injury and the liver biopsy result of non-caseating granulomas. Although five different antibiotics including ciprofloxacin, metronidazole, vancomycin, imipenem/cilastatin, and cefepime were provided, the timing of liver injury and pharmacology of each drug imply that ciprofloxacin was the most likely antibiotic causing DILI, given the pharmacology of each antibiotics. This case is unique because miliary TB was complicated by adrenal insufficiency and drug-induced cholestatic liver injury, but acute liver injury was fully reversed after corticosteroid treatment. This implies an immune-mediated etiology of DILI, especially ciprofloxacin-induced cholestatic liver injury. DILI is challenging to diagnose in the setting of multiple comorbidities. Therefore, it is crucial that clinicians are to be aware of signs and symptoms of DILI, in that delayed diagnose and treatment may have fatal consequences.

    2016-01-01

    Objective To investigate the incidence of adrenal insufficiency (AI) in patients with spinal cord injury (SCI) with symptoms similar to those of AI and to assess the relevance of AI and large-dose glucocorticoids in SCI. Methods The medical records of 228 patients who were admitted to the rehabilitation center after SCI from January 2014 to January 2016 were reviewed retrospectively. Twenty-nine of 228 patients had persistent symptoms suspicious for AI despite continuous care for more than 4 weeks. Therefore, adrenocorticotropic hormone (ACTH) stimulation tests were conducted in these 29 patients. Results Twelve of these 29 patients (41.4%) with SCI who manifested AI-like symptoms were diagnosed as having AI. Among these 29 patients, 15 patients had a history of large-dose glucocorticoid treatment use and the other 14 patients did not have such a history. Ten of the 15 patients (66.7%) with SCI treated with large-dose glucocorticoids after injury were diagnosed as having AI. In 12 patients with AI, the most frequent symptom was fatigue (66%), followed by orthostatic dizziness (50%), and anorexia (25%). In the chi-square test, the presence of AI was positively correlated with large-dose glucocorticoid use (p=0.008, Fisher exact test). Conclusion Among the patients with SCI who manifested similar symptoms as those of AI, high incidence of AI was found especially in those who were treated with large-dose glucocorticoids. During management of SCI, if a patient has similar symptoms as those of AI, clinicians should consider the possibility of AI, especially when the patient has a history of large-dose glucocorticoid use. Early recognition and treatment of the underlying AI should be performed. PMID:28119833

    The insulin tolerance test (ITT) is considered the gold standard for the diagnosis of adrenal insufficiency (AI). However, the test is unpleasant to perform and has the risk of serious complications. We therefore evaluated the clinical applicability of GHRP6, which is a known activator of the hypothalamic-pituitary-adrenal (HPA) axis, to test for AI. For this purpose a comparative clinical study was designed. Forty-nine patients with suspected dysfunction of the HPA axis and 20 healthy controls were enrolled. The ITT was performed in patients, and GHRP6 (1 microg/kg) testing in patients and controls. Serum cortisol over 90 min after GHRP6, in comparison to the ITT, was the main outcome measure. Thirty-one patients had a peak cortisol response of less than 500 nmol/l during ITT and were considered adrenal insufficient. For GHRP6, the mean cortisol peak was 227+/-25.7 nmol/l in the AI group versus 395+/-35.3 nmol/l in the adrenal sufficient (AS) group. ROC analysis of peak cortisol levels during GHRP6 test suggested an optimal threshold of 299 nmol/l for the diagnosis of AI (Sens. 71.0%, Spec. 77.8%). Applying upper (416 nmol/l) and lower (137 nmol/l) thresholds with high specificities in combination with early morning cortisol established the diagnosis in nearly half of the patients, even when the GHRP6 test is limited to 30 min duration. GHRP6 led to significant activation of the HPA axis with no detectable side effects, but had limited accuracy in comparison to the ITT.

    Background. Multidrug-resistant tuberculosis (MDR-TB) is a major public health care concern that affects the life of millions of people around the world. The association of tuberculosis and adrenal insufficiency is well known; however, it is thought to be less prevalent every time. A spike in TB incidence and a lack of evidence of this association in patients with MDR-TB call for reassessment of an illness (adrenal dysfunction) that if not diagnosed could seriously jeopardize patients' health. Objective. To determine the prevalence of adrenocortical insufficiency in patients with MDR-TB using the low-dose (1 μg) ACTH stimulation test at baseline and at 6–12 months of follow-up after antituberculosis treatment and culture conversion. Methods. A total of 48 men or women, aged ≥18 years (HIV-negative patients diagnosed with pulmonary MDR-TB) were included in this prospective observational study. Blood samples for serum cortisol were taken at baseline and 30 and 60 minutes after 1 μg ACTH stimulation at our tertiary level university hospital before and after antituberculosis treatment. Results. Forty-seven percent of subjects had primary MDR-TB; 43.8% had type 2 diabetes; none were HIV-positive. We found at enrollment 2 cases (4.2%) of adrenal insufficiency taking 500 nmol/L as the standard cutoff point value and 4 cases (8.3%) alternatively, using 550 nmol/L. After antituberculosis intensive phase drug-treatment and a negative mycobacterial culture (10.2 ± 3.6 months) adrenocortical function was restored in all cases. Conclusions. In patients with MDR-TB, using the low-dose ACTH stimulation test, a low prevalence of mild adrenal insufficiency was observed. After antituberculosis treatment adrenal function was restored in all cases. Given the increasing and worrying epidemic of MDR-TB these findings have important clinical implications that may help clinicians and patients make better decisions when deciding to test for adrenocortical dysfunction or

    The authors report the case of a 69-year-old man with chronic obstructive pulmonary disease and previous pulmonary tuberculosis, who presented to the emergency department with abdominal and low back pain, anorexia and weight loss, rapidly evolving into shock. An initial CT scan revealed pulmonary condensation with associated cavitation and an iliopsoas mass suggestive of a psoas abscess. He was admitted in an intensive care unit unit; after a careful examination and laboratory assessment, the aetiology was yet undisclosed. MRI showed multiple retroperitoneal lymphadenopathies, bulky nodular adrenal lesions and bilateral iliac lytic lesions. Hypocortisolism was detected and treated with steroids. A CT-guided biopsy to the psoas mass and lytic lesions identified infiltration of non-small lung carcinoma. The patient died within days. Psoas metastases and adrenal insufficiency as initial manifestations of malignancy are rare and can be misdiagnosed, particularly in the absence of a known primary tumour.

    Malakoplakia is an uncommon but distinctive type of chronic granulomatous inflammation that occurs most commonly in the genitourinary tract, especially the urinary bladder. Most patients have associated conditions characterized by some degree of immunosuppression, as seen in solid-organ transplants, autoimmune diseases requiring steroid use, chemotherapy, chronic systemic diseases, alcohol abuse and poorly controlled diabetes. We report an unusual case of the renal malakoplakia that involved the perirenal space, extending to the descending colon in a 65-year-old Korean woman with secondary adrenal insufficiency and diabetes mellitus.

    Relative adrenal insufficiency in sepsis has been extensively debated on; however, accurate diagnosis and therapeutic intervention remain controversial. The authors aimed to evaluate adrenocorticotropic hormone (ACTH), salivary cortisol, total cortisol and estimated plasma-free cortisol, cholesterol, and lipoproteins as predictors of adrenal insufficiency in patients within 24 h of septic shock diagnosis. This prospective study evaluated all hospitalized patients older than 18 years who developed septic shock and were using vasoactive drugs within 24 h of diagnosis. Blood and saliva samples were drawn at baseline and 60 min (T60) after 250 μg tetracosactide intravenous injection. Patients were divided into two groups: responders (Δ [T60 minus baseline] total cortisol >9 μg/dL) and nonresponders (Δ total cortisol ≤ 9 μg/dL or baseline total cortisol <10 μg/dL). The latter group was considered to have adrenal insufficiency. A total of 7,324 hospitalized patients were monitored, and 34 subjects with septic shock were included in the analysis. Adrenal insufficiency was found in 32.4%. Total cholesterol, high-density lipoprotein cholesterol, triglycerides, and salivary cortisol did not differ between groups. Estimated plasma-free cortisol was not better than total plasma cortisol in estimating adrenal function. Baseline endogenous ACTH was higher in nonresponders than responders (55.5 pg/mL vs. 18.3 pg/mL, respectively; P = 0.01). The cutoff ACTH value that discriminated patients with adrenal insufficiency was 31.5 pg/mL. Thus, endogenous ACTH measured within 24 h of septic shock diagnosis could predict adrenal response to tetracosactide.

    Congenital hyperinsulinism (CHI) caused by a glucokinase- (GCK-) activating mutation shows autosomal dominant inheritance, and its severity ranges from mild to severe. A 43-year-old female with asymptomatic hypoglycemia (47 mg/dL) was diagnosed as partial adrenal insufficiency and the administration of hydrocortisone (10 mg/day) was initiated. Twelve years later, her 8-month-old grandchild was diagnosed with CHI. Heterozygosity of exon 6 c.590T>C (p.M197T) was identified in a gene analysis of GCK, which was also detected in her son and herself. The identification of GCK-activating mutations in hyperinsulinemic hypoglycemia patients may be useful for a deeper understanding of the pathophysiology involved and preventing unnecessary glucocorticoid therapy.

    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.

    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, p<.001). Healthy individuals showed the expected pattern of stress-related early lymphocyte increase with subsequent decrease below baseline. The opposite pattern was observed in granulocytes. While exhibiting a similar initial increase, lymphocytes kept increasing over the following 2h in untreated patients. HC treatment buffered this effect (interaction effects--lymphocyte%: F=7.31, p<.001; granulocyte%: F=7.71, p<.001). Using CAI in humans as a model confirms cortisol'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.

    The aim of this study was to assess the effect of continuous propofol sedation plus prolonged mechanical ventilation on adrenal insufficiency (AI) in patients with traumatic brain injury (TBI). Eighty-five adult patients diagnosed with moderate TBI (Glasgow Coma Scale (GCS) score 9-13) from October 2011 to October 2012 were included in this prospective study. The patients comprised three groups: no mechanical ventilation and sedation (n=27), mechanical ventilation alone (n=24) and mechanical ventilation plus sedation (n=34). The low-dose short Synacthen test was performed at 8:00 on the first, third, and fifth days after TBI. Logistic regression analysis was performed to identify factors affecting the use of mechanical ventilation and sedation, and the incidence of AI. On the fifth day after injury, the mean baseline cortisol and simulated cortisol levels were significantly lower in the mechanical ventilation plus sedation group compared with the other two groups. Multivariate regression analysis showed that the Acute Physiology and Chronic Health Evaluation (APACHE) score was independently associated with treatment with mechanical ventilation and sedation compared to mechanical ventilation alone. Furthermore, hypoxemia on admission and shock were associated with the development of AI. The findings showed that sedation is associated with an increased incidence of AI. Patients with TBI who are treated with continuous sedation should be monitored for AI carefully.

    Abstract Hyponatremia may be one of the clinical manifestations of adrenal insufficiency (AI) and during the diagnostic workup of hyponatremic patients investigation of AI should be included. We report the case of an 82-year-old patient who was admitted to our hospital with clinical symptoms and laboratory findings of hyponatremia. Following the diagnostic algorithm of hyponatremia we reached the diagnosis of AI. Clinician's attention must focus on the underlying cause of AI which in this case was hidden in a miscommunication between hypothalamus and pituitary due to an ectopic posterior pituitary lobe and became apparent by a pituitary magnetic resonance imaging (MRI) scan. Treatment with oral hydrocortisone resulted in full clinical recovery and electrolyte balance, which was maintained after 7 months of follow-up. Secondary AI is related with hyponatremia through increased ADH secretion. Although a hyponatremic episode may be the first presentation of AI, clinical suspicion is of high importance in order to place the right diagnosis. Disruption of communication between hypothalamus and pituitary is a rare but considerable cause of AI. PMID:26962783

    This retrospective study was carried out to estimate the prevalence of an adrenal crisis at a provincial hospital in Thailand over a period of 1 year, and also to explore the relationship between adrenal insufficiency and over-the-counter medicine (OTCM) ingestion. We recruited those patients admitted at Sisaket Hospital between October 2012 and October 2013 who were diagnosed with shock and adrenal insufficiency or adrenal crisis. Of 2,435 patients diagnosed with shock from all causes, 62 (2.55 %) were diagnosed with adrenal crisis, of whom 31 (50.0%) gave a history of OTCM ingestion. This study suggests adrenal crisis with shock is not that uncommon and that the use of OTCM may be the prime culprit.

    The insulin tolerance test (ITT) is the gold standard for diagnosing adrenal insufficiency (AI) after pituitary surgery. The ITT is unpleasant for patients, requires close medical supervision and is contraindicated in several comorbidities. The aim of this study was to analyze whether tumor size, remission rate, preoperative, and early postoperative baseline hormone concentrations could serve as predictors of AI in order to increase the diagnostic accuracy of morning serum cortisol. This prospective study enrolled 70 consecutive patients with newly diagnosed pituitary adenomas.

    Abstract The insulin tolerance test (ITT) is the gold standard for diagnosing adrenal insufficiency (AI) after pituitary surgery. The ITT is unpleasant for patients, requires close medical supervision and is contraindicated in several comorbidities. The aim of this study was to analyze whether tumor size, remission rate, preoperative, and early postoperative baseline hormone concentrations could serve as predictors of AI in order to increase the diagnostic accuracy of morning serum cortisol. This prospective study enrolled 70 consecutive patients with newly diagnosed pituitary adenomas. Thirty-seven patients had nonfunctioning pituitary adenomas (NPA), 28 had prolactinomas and 5 had somatotropinomas. Thyroxin (T4), thyrotropin (TSH), prolactin, follicle-stimulating hormone (FSH), luteinizing hormone (LH), testosterone, and insulin-like growth factor 1 (IGF-I) were measured preoperatively and on the sixth postoperative day. Serum morning cortisol was measured on the third postoperative day (CORT3) as well as the sixth postoperative day (CORT6). Tumor mass was measured preoperatively and remission was assessed 3 months after surgery. An ITT was performed 3 to 6 months postoperatively. Remission was achieved in 48% of patients and AI occurred in 51%. Remission rates and tumor type were not associated with AI. CORT3 had the best predictive value for AI (area under the curve (AUC) 0.868, sensitivity 82.4%, specificity 83.3%). Tumor size, preoperative T4, postoperative T4, and TSH were also associated with AI in a multivariate regression model.

    During the period included between January 1970 and December 1990, we studied 242 patients with manometric and radiological diagnosis of esophageal achalasia. Eight of these patients (3.3%) developed during the evolution of their disease an esophageal carcinoma. Eight cases showed histologic type of epidermoid carcinoma: 3 differentiated, 3 semi-differentiated and 2 anaplastic. Therapy for achalasia was: one patient, Heller myotomy, 4 patients, dilatations with bougies in numerous opportunities, and the other two patients receive no treatment for achalasia. Two patients reported tracheobronchial fistulas as complication of carcinoma. Treatment received for carcinoma included: three patients, radiotherapy (4000 rads); one patient, chemotherapy; one patient, chemotherapy and radiotherapy, one resection surgery and two patients feeding gastrostomy. All of the eight patients died within the year of diagnosis of epidermoid carcinoma.

    There have been some breakthroughs in the diagnosis and treatment of esophageal achalasia in the past few years. First, the introduction of high-resolution manometry with pressure topography plotting as a new diagnostic tool has made it possible to classify achalasia into three subtypes. The most favorable outcome is predicted for patients receiving treatment for type II achalasia (achalasia with compression). Patients with type I(classic achalasia) and type III achalasia (spastic achalasia) experience a less favorable outcome. Second, the first multicenter randomized controlled trial published by the European Achalasia Trial group reported 2-year follow-up results indicating that laparoscopic Heller myotomy was not superior to endoscopic pneumatic dilation (PD). Although the follow-up period was not long enough to reach a convincing conclusion, it merits the continued use of PD as a generally available technique in gastroenterology. Third, the novel endoscopic technique peroral endoscopic myotomy is a promising option for treating achalasia, but it requires increased experience and cautious evaluation. Despite all this good news, the bottom line is a real breakthrough from the basic studies to identify the actual cause of achalasia that may impede treatment success is still anticipated.

    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 <138 nmol/l, or if its response was inadequate in the low-dose short synacthen test. Seventy-four subjects underwent TNS (and 17 of whom also underwent RT), and 23 were on primary medical therapy: overall we diagnosed 21 cases of CAI. Duration of 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.

    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 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 (p<0.001). More impairments in physical aspects of QoL correlated with higher CORThair and higher daily hydrocortisone intake (p<0.05), an effect that was more pronounced in female patients. Regression analyses including both CORThair and hydrocortisone intake revealed a significant negative contribution of higher hydrocortisone intake on physical aspects of QoL (p≤0.046), whereas no significant contribution was found for CORThair. The present study showed that patients with AI 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.

    The aim of the study was to characterize the presence of diverse CD4 and CD8 T cell subsets and regulatory cells in peripheral blood and lower oesophageal sphincter (LES) from a young patient with BE/achalasia without treatment versus achalasia group. In order to characterize the circulating cells in this patient, a cytometric analysis was performed. LES tissue was evaluated by double-immunostaining procedure. Five healthy blood donors, 5 type achalasia patients, and 5 oesophagus tissue samples (gastrooesophageal junction) from transplant donors were included as control groups. A conspicuous systemic inflammation was determined in BE/achalasia patient and achalasia versus healthy volunteer group. Nonetheless, a predominance of Th22, Th2, IFN-α-producing T cells, Tregs, Bregs, and pDCregs was observed in BE/achalasia patient versus achalasia group. A low percentage of Th1 subset in BE/achalasia versus achalasia group was determined. A noticeable increase in tissue of Th22, Th17, Th2, Tregs, Bregs, and pDCregs was observed in BE/achalasia versus achalasia group. Th1 subset was lower in the BE/achalasia patient versus achalasia group. This study suggests that inflammation is a possible factor in the pathogenesis of BE/achalasia. Further research needs to be performed to understand the specific cause of the correlation between BE and achalasia. PMID:27752370

    Achalasia is a primary esophageal motility disorder, which shows distinct clinical, manometric, radiologic, and pathologic features. Available treatment strategies are pharmacological, endoscopic or surgical. In the past decades preferred treatment has alternated between surgical myotomy (presently Laparoscopic Heller Myotomy [LHM]) and endoscopic balloon dilation (EBD). While surgical myotomy promises superior long-term results and significantly less retreatment, endoscopic balloon dilation is initially far less invasive and yields comparable results after redilation. Peroral Endoscopic Myotomy (POEM) aims to combine the minimal invasive approach through the mouth with the better long-term results after LHM. Initial findings in the literature point to comparable success-rates after POEM and LHM. In the literature complication rates are similar to those obtained after surgery. This new interventional technique should be subject to randomized controlled trials and compared to EBD and LHM.

    Achalasia is a motility disorder of the esophagus characterized by dysphagia, regurgitation of undigested food, chest pain, weight loss and respiratory symptoms. The most common form of achalasia is the idiopathic one. Diagnosis largely relies upon endoscopy, barium swallow study, and high resolution esophageal manometry (HRM). Barium swallow and manometry after treatment are also good predictors of success of treatment as it is the residue symptomatology. Short term improvement in the symptomatology of achalasia can be achieved with medical therapy with calcium channel blockers or endoscopic botulin toxin injection. Even though few patients can be cured with only one treatment and repeat procedure might be needed, long term relief from dysphagia can be obtained in about 90% of cases with either surgical interventions such as laparoscopic Heller myotomy or with endoscopic techniques such pneumatic dilatation or, more recently, with per-oral endoscopic myotomy. Age, sex, and manometric type by HRM are also predictors of responsiveness to treatment. Older patients, females and type II achalasia are better after treatment compared to younger patients, males and type III achalasia. Self-expandable metallic stents are an alternative in patients non responding to conventional therapies.

    The low incidence (1:100,000) makes primary idiopathic achalasia a problem of special importance. Patients often have a long medical history of suffering before the diagnosis is established and adequate therapy provided. Surgeons who perform antireflux surgery must be certain of detecting achalasia patients within their collective of gastroesophageal reflux disease (GERD) patients to avoid contraindicated fundoplication. The current gold standard for establishing the diagnosis of achalasia is manometry. Especially in early stages, symptom evaluation, endoscopy and barium swallow lack adequate sensitivity. High-resolution manometry (HRM) is increasingly used and allows characterization of different achalasia types (i.e. type I classical achalasia, type II panesophageal pressurization and type III spasmodic achalasia) and differentiation from other motility disorders (e.g. distal esophageal spasm, jackhammer esophagus and nutcracker esophagus). For patients over 45 years of age additional endoscopic ultrasound and computed tomography are recommended to exclude pseudoachalasia. A curative treatment restoring normal esophageal function does not exist; however, there are good options for symptom control. Therapy aims are abolishment of dysphagia, improvement of esophageal clearance, prevention of reflux and abolishment of chest pain. The current standard treatment is cardiomyotomy, which was first described 100 years ago by the German surgeon Ernst Heller and has been shown to be clearly superior when compared to endoscopic treatment (e.g. botox injection and balloon dilatation). Heller's myotomy procedure is preferentially performed via the laparoscopic route and combined with partial fundoplication. Currently, an alternative to performing Heller's myotomy via the endoscopic route is under intensive investigation in several centers worldwide. The peroral endoscopic myotomy (POEM) procedure has shown very promising initial results and warrants further clinical

    Esophageal motility disorders are classified primary and secondary, and primary esophageal motility disorders are classified esophageal achalasia and other diseases by manometry. An esophageal emptying disorder associated with insufficient relaxation of the lower esophageal sphincter (LES) and elimination of peristaltic waves on the esophageal body is the major abnormality of achalasia. Esophagogram, endoscopy, and manometry are used for diagnosis. As pharmacological therapy, administration of a calcium channel blocker or nitrate is useful. The pharmacological therapy is not recommended as long-term basic therapy but as a temporary treatment. At 1st, the balloon dilation method is chosen in treatment of achalasia Surgical treatment is indicated in the following cases: (1) Patients uneffected by balloon dilation, (2) Flask type with grade II to III dilation, and sigmoid type, (3) the gradual progression to the pathophysiological stage, (4) young patients, (5) complicated with esophageal cancer. Laparoscopic Heller-Dor procedure is the most popular surgical procedure, recently. It is somewhat difficult to perform surgical treatment for this functional disease. We should select the most suitable individualized treatment with efficient comprehension of the pathophysiological situation.

Its main feature is the lack of esophageal peristalsis, the lower esophageal sphincter pressure and to reduce the swallow's relaxation response. Lower esophageal muscular dissection is one of the main ways to treat esophageal achalasia. At present, the period of muscular layer under the thoracoscope esophagus dissection is one of the treatment of esophageal achalasia.

    Achalasia is defined by esophageal outflow obstruction from abnormal relaxation of the lower esophageal sphincter (LES) due to deranged inhibitory control. In genetically predisposed individuals, an autoimmune response to an unknown inciting agent, perhaps a viral infection, results in inflammation and sometimes loss of myenteric plexus ganglia and neurons. The net result is varying degrees of inhibitory dysfunction, at times associated with imbalanced and exaggerated excitatory function, with manometrically distinct achalasia phenotypes on high resolution manometry. There is new evidence in the current issue of this Journal suggesting that type 1 achalasia, with esophageal outflow obstruction and absent esophageal body contractility, is an end-stage phenotype from progression of type 2 achalasia, which is characterized by panesophageal compartmentalization of pressure in the untreated patient, and partial recovery of peristalsis after treatment. Esophageal outflow obstruction with premature peristalsis (type 3 achalasia) or intact peristalsis may result from plexitis in the myenteric plexus but can also be encountered in other settings including chronic opioid medication usage and structural processes at the esophagogastric junction and distally. In most instances when idiopathic esophageal outflow obstruction is confirmed, some form of pharmacologic manipulation or disruption of the LES provides durable symptom relief. This review will focus on current understanding of pathophysiology, diagnosis, and principles of management of achalasia in light of emerging literature on the topic.

    2016-01-01

    Summary Adrenal haemorrhage is a rare cause of adrenal crisis, which requires rapid diagnosis, prompt initiation of parenteral hydrocortisone and haemodynamic monitoring to avoid hypotensive crises. We herein describe a case of bilateral adrenal haemorrhage after hemicolectomy in a 93-year-old female with high-grade colonic adenocarcinoma. This patient’s post-operative recovery was complicated by an acute hypotensive episode, hypoglycaemia and syncope, and subsequent computed tomography (CT) scan of the abdomen revealed bilateral adrenal haemorrhage. Given her labile blood pressure, intravenous hydrocortisone was commenced with rapid improvement of blood pressure, which had incompletely responded with fluids. A provisional diagnosis of hypocortisolism was made. Initial heparin-induced thrombocytopenic screen (HITTS) was positive, but platelet count and coagulation profile were both normal. The patient suffered a concurrent transient ischaemic attack with no neurological deficits. She was discharged on a reducing dose of oral steroids with normal serum cortisol levels at the time of discharge. She and her family were educated about lifelong steroids and the use of parenteral steroids should a hypoadrenal crisis eventuate. Learning points: Adrenal haemorrhage is a rare cause of hypoadrenalism, and thus requires prompt diagnosis and management to prevent death from primary adrenocortical insufficiency. Mechanisms of adrenal haemorrhage include reduced adrenal vascular bed capillary resistance, adrenal vein thrombosis, catecholamine-related increased adrenal blood flow and adrenal vein spasm. Standard diagnostic assessment is a non-contrast CT abdomen. Intravenous hydrocortisone and intravenous substitution of fluids are the initial management. A formal diagnosis of primary adrenal insufficiency should never delay treatment, but should be made afterwards. PMID:27855238

  18. Achalasia and chronic opiate use: innocent bystanders or associated conditions?

    High-resolution manometry identifies three subtypes of achalasia. However, type 3 differs from classic achalasia. Although opiates affect esophageal motility, opiate use and achalasia have not been studied. Patients with a new diagnosis of achalasia at Mayo Clinic Rochester between June 1, 2012 and January 3, 2014 were identified. Clinical records were reviewed to assess symptoms, opiate use, and therapy. Fifty-six patients with achalasia were identified, 14 (25%) were on opiates. Opiate prescription was unrelated to achalasia in all cases, with chronic back and joint pain constituting the majority. Of patients on opiates, five (36%) had type 3 achalasia compared with four (10%) not on opiates (P = 0.02). No patients on opiates had type 1 achalasia. Clinical presentation did not differ with opiates, although those on opiates were more likely to report chest pain (39 vs. 14%, P = 0.05) and less likely to have esophageal dilation (62 vs. 82%, P = 0.13), none with greater than 5-cm diameter. Contractile vigor was greater with opiate use, with distal contractile integral of 7149 versus 2615.5 mmHg/cm/second (P = 0.08). Treatment response was inferior on opiates, with persistent symptoms in 22% compared with 3% without opiates (P = 0.06). Opiate use is common in type 3 achalasia, with the majority of patients on opiates. No patients on opiates were diagnosed with type 1 achalasia. Manometric findings of type 3 achalasia mimic those induced by opiates, suggesting a physiologic mechanism for opiate induced type 3 achalasia. Treatment outcome is inferior with opiates, with opiate cessation perhaps preferable. Further studies assessing opiate use and achalasia are needed.

    Achalasia is the most common primary motility disorder of the esophagus and presents as dysphagia to solids and liquids. It is characterized by impaired deglutitive relaxation of the lower esophageal sphincter. High-resolution manometry allows for definitive diagnosis and classification of achalasia, with type II being the most responsive to therapy. Since no cure for achalasia exists, early diagnosis and treatment of the disease is critical to prevent end-stage disease. The central tenant of diagnosis is to first rule out mechanical obstruction due to stricture or malignancy, which is often accomplished by endoscopic and fluoroscopic examination. Therapeutic options include pneumatic dilation (PD), surgical myotomy, and endoscopic injection of botulinum toxin injection. Heller myotomy and PD are more efficacious than pharmacologic therapies and should be considered first-line treatment options. Per oral endoscopic myotomy (POEM) is a minimally-invasive endoscopic therapy that might be as effective as surgical myotomy when performed by a trained and experienced endoscopist, although long-term data are lacking. Overall, therapy should be individualized to each patient’s clinical situation and based upon his or her risk tolerance, operative candidacy, and life expectancy. In instances of therapeutic failure or symptom recurrence re-treatment is possible and can include PD or POEM of the wall opposite the site of prior myotomy. Patients undergoing therapy for achalasia require counseling, as the goal of therapy is to improve swallowing and prevent late manifestations of the disease rather than to restore normal swallowing, which is unfortunately impossible.

    A 3-month-old German shepherd puppy with a congenitally dilated oesophagus had radiographic, cinefluoroscopic, and oesophageal motility studies before a modified Heller operation was performed. Subsequent examination of the oesophagus revealed no ganglion cells, and the condition was considered to be identical with human achalasia. In dogs, this appears to be more common in the German shepherd breed. Images PMID:6069217

    Endoscopic therapy for achalasia is directed at disrupting or weakening the lower esophageal sphincter (LES). The two most commonly utilized endoscopic interventions are large balloon pneumatic dilation (PD) and botulinum toxin injection (BTI). These interventions have been extensively scrutinized and compared with each other as well as with surgical disruption (myotomy) of the LES. PD is generally more effective in improving dysphagia in achalasia than BTI, with the latter reserved for infirm older people, and PD may approach treatment results attained with myotomy. However, PD may need to be repeated. Small balloon dilation and endoscopic stent placement for achalasia have only been used in select centers. Per oral endoscopic myotomy is a newer endoscopic modality that will likely change the treatment paradigm for achalasia. It arose from the field of natural orifice transluminal endoscopic surgery and represents a scarless endoscopic approach to Heller myotomy. This is a technique that requires extensive training and preparation and thus there should be rigorous accreditation and monitoring of outcomes to ensure safety and efficacy. PMID:23503707

    1997-01-01

    Background—The diagnosis and classification of oesophageal motility disorders is currently based on assessment of the phasic contractile activity of the oesophagus. Tonic muscular contraction of the oesophageal body (oesophageal tone) has not been well characterised. 
Aim—To quantify oesophageal tonic activity in healthy subjects and in patients with achalasia. 
Patients—Oesophageal tone was measured in 14 patients with untreated achalasia and in 14 healthy subjects. In eight patients with achalasia, oesophageal tone was again measured one month after either endoscopic or surgical treatment. 
Methods—Tonic wall activity was quantified by means of a flaccid intraoesophageal bag, 5 cm long and of 120 ml maximal capacity, which was placed and maintained 5 cm above the lower oesophageal sphincter and connected to an external electronic barostat. The experimental design included measurement of oesophageal basal tone and compliance as well as the oesophageal tone response to a nitric oxide donor (0.5 ml amyl nitrite inhalation). 
Results—Oesophageal basal tone, expressed as the intrabag (intraoesophageal) volume at a minimal distending pressure (2 mm Hg), did not differ significantly between patients with achalasia and healthy controls (6.6 (2.5) ml versus 4.1 (0.8) ml, respectively). Oesophageal compliance (volume/pressure relation during intraoesophageal distension) was significantly increased in achalasia (oesophageal extension ratio: 3.2 (0.4) ml/mm Hg versus 1.9 (0.2) ml/mm Hg; p< 0.01). Amyl nitrite inhalation induced oesophageal relaxation both in patients and in controls, but the magnitude of relaxation was greater in the latter (intrabag volume increase: 15.3 (2.4) ml versus 36.2 (7.1) ml; p<0.01). 
Conclusion—In patients with achalasia, oesophageal tonic activity, and not only phasic activity, is impaired. Although oesophageal compliance is increased, residual oesophageal tone is maintained so that a significant relaxant response may occur

    Idiopathic achalasia is an archetype esophageal motor disorder, causing significant impairment of eating ability and reducing quality of life. The pathophysiological underpinnings of this condition are loss of esophageal peristalsis and insufficient relaxation of the lower esophageal sphincter (LES). The clinical manifestations include dysphagia for both solids and liquids, regurgitation of esophageal contents, retrosternal chest pain, cough, aspiration, weight loss and heartburn. Even though idiopathic achalasia was first described more than 300 years ago, researchers are only now beginning to unravel its complex etiology and molecular pathology. The most recent findings indicate an autoimmune component, as suggested by the presence of circulating anti-myenteric plexus autoantibodies, and a genetic predisposition, as suggested by observed correlations with other well-defined genetic syndromes such as Allgrove syndrome and multiple endocrine neoplasia type 2 B syndrome. Viral agents (herpes, varicella zoster) have also been proposed as causative and promoting factors. Unfortunately, the therapeutic approaches available today do not resolve the causes of the disease, and only target the consequential changes to the involved tissues, such as destruction of the LES, rather than restoring or modifying the underlying pathology. New therapies should aim to stop the disease at early stages, thereby preventing the consequential changes from developing and inhibiting permanent damage. This review focuses on the known characteristics of idiopathic achalasia that will help promote understanding its pathogenesis and improve therapeutic management to positively impact the patient’s quality of life.

    We carried out a detailed analysis of rat model of esophageal achalasia previously developed by us. Manifest morphological and functional disorders were observed in experimental achalasia: hyperplasia of the squamous epithelium, reduced number of nerve fibers, excessive growth of fibrous connective tissue in the esophageal wall, high contractile activity of the lower esophageal sphincter, and reduced motility of the longitudinal muscle layer. Changes in rat esophagus observed in experimental achalasia largely correlate with those in esophageal achalasia in humans. Hence, our experimental model can be used for the development of new methods of disease treatment.

    Achalasia is a rare esophageal motility disorder that is usually idiopathic in origin. It is characterized by dysphagia, and patients often have chest pain, regurgitation, weight loss, and an abnormal barium radiograph showing esophageal dilation with narrowing at the gastroesophageal junction. Abnormal or absent esophageal peristalsis and impaired relaxation of the lower esophageal sphincter (LES) are typically seen on esophageal manometry. The advent of high resolution manometry (HRM) has allowed more precise diagnosis of achalasia, subtype designation, and differentiation from other esophageal motor disorders with an initial seminal publication in 2008 followed by further refinements of what has been termed the Chicago classification. Potential treatments include drugs, endoscopic botulinum toxin injection, balloon dilation, traditional surgery (usually laparoscopic Heller myotomy; LHM), and a novel, less invasive, natural orifice transluminal endoscopic surgery (NOTES) approach to Heller myotomy termed peroral endoscopic myotomy (POEM). The first human POEM was performed in 2008, with the first publication appearing in 2010 and evidence now rapidly accumulating showing POEM to be comparable to traditional surgery in terms of clinical success and radiologic and manometric post-therapy outcomes. This review discusses the diagnosis and management of achalasia with particular emphasis on the recent developments of HRM and POEM, which arguably represent the most important advances in the field since the advent of laparoscopic Heller myotomy in the 1990s.

    This study assessed adrenal function in patients with paracoccididioidomycosis who had been treated to determine a possible connection between high antibody titers and adrenal dysfunction attributable to persistence of the fungus in adrenal gland. Adrenal gland function was studied in 28 previously treated patients, 2 (7.1%) of whom were shown to have adrenal insufficiency and 7 (259%) who showed a below normal response to stimuli by adrenocorticotropic hormone. Paracoccidioides brasiliensis was detected in the adrenal gland from one of the patients with adrenal insufficiency. Although the study failed to demonstrate a significant difference between high antibody titers and low cortisol levels, the proportion of adrenal insufficiency detected and the subnormal response to adrenocorticotropic hormone confirmed that adrenal damage is an important sequela of paracoccidioidomycosis. Studies with a larger number of patients should be conducted to confirm the hypothesis of persistence of P. brasiliensis in adrenal gland after therapy. PMID:20595488

    Disorders of the adrenal glands frequently have secondary neurological manifestations, while some diseases that involve the central nervous system are accompanied by adrenal gland dysfunction. Excessive corticosteroid secretions in primary or secondary Cushing's syndrome causes muscle weakness and behavioral disturbances, such as emotional lability and sometimes depression, while adrenal insufficiency may cause fatigue, weakness, and depression. Adrenoleukodystrophy and adrenoneuromyelopathy are X-linked recessive disorders of the metabolism of very long chain fatty acids that manifest with white matter abnormalities of the brain, myelopathy and/or neuropathy, as well as adrenal insufficiency. Other disorders of the adrenal glands include hyperaldosteroidism, which may cause weakness from hypokalemia. Dysfunction of the adrenal medulla causes excessive or deficient secretion of catecholamines, primarily causing cardiovascular symptoms. This chapter reviews the clinical manifestations and diagnostic aspects and treatment of the various disorders of the adrenal glands. Some of the congenital adrenal diseases are also discussed.

    2013-01-01

    Achalasia is a motility disorder of the esophagus, characterized by aperistalsis of the esophageal body and incomplete relaxation of the lower esophageal sphincter (LES). Treatment of achalasia is currently aimed at decreasing the resting pressure in the LES. Peroral endoscopic myotomy (POEM) is an emerging novel endoscopic procedure for the treatment of achalasia with initial data suggesting an acceptable safety profile, excellent short-term symptom resolution, low incidence of postprocedural gastroesophageal reflux (GER), and improvement in manometric outcomes. Further prospective randomized trials are required to evaluate the long-term effectiveness of this promising technique compared to other treatment modalities for achalasia. In this review we outline the technical aspects of POEM, summarize the available data on safety and outcomes, and suggest future directions for further advancement of this minimally invasive approach for the treatment of achalasia.

  11. The prevalence of autoimmune disease in patients with esophageal achalasia.

    2012-04-01

    Achalasia is a rare disease of the esophagus that has an unknown etiology. Genetic, infectious, and autoimmune mechanisms have each been proposed. Autoimmune diseases often occur in association with one another, either within a single individual or in a family. There have been separate case reports of patients with both achalasia and one or more autoimmune diseases, but no study has yet determined the prevalence of autoimmune diseases in the achalasia population. This paper aims to compare the prevalence of autoimmune disease in patients with esophageal achalasia to the general population. We retrospectively reviewed the charts of 193 achalasia patients who received treatment at Toronto's University Health Network between January 2000 and May 2010 to identify other autoimmune diseases and a number of control conditions. We determined the general population prevalence of autoimmune diseases from published epidemiological studies. The achalasia sample was, on average, 10-15 years older and had slightly more men than the control populations. Compared to the general population, patients with achalasia were 5.4 times more likely to have type I diabetes mellitus (95% confidence interval [CI] 1.5-19), 8.5 times as likely to have hypothyroidism (95% CI 5.0-14), 37 times as likely to have Sjögren's syndrome (95% CI 1.9-205), 43 times as likely to have systemic lupus erythematosus (95% CI 12-154), and 259 times as likely to have uveitis (95% CI 13-1438). Overall, patients with achalasia were 3.6 times more likely to suffer from any autoimmune condition (95% CI 2.5-5.3). Our findings are consistent with the impression that achalasia's etiology has an autoimmune component. Further research is needed to more conclusively define achalasia as an autoimmune disease.

    We measured quantitative esophageal transit, expressed as percentage of esophageal retention, before and after pneumatic dilatation in two patients with achalasia. In the sitting position they ingested a 500 ml liquid meal containing 500 muCi technetium Tc 99m sulfur colloid. Radioactivity counts of the entire esophagus were plotted at five-minute intervals for 30 minutes. In five normal control subjects the esophagus essentially cleared in less than one minute. Both patients with achalasia had definite retention 30 minutes before dilatation and had quantitative improvement after dilatation. Radionuclide scintigraphic esophageal transit probably correlates better than other parameters with the physiologic degree of obstruction in achalasia.

    Computed tomography (CT) of the adrenal glands was performed on seven patients who had histologically proved disseminated histoplasmosis. All seven patients showed some degree of adrenal gland abnormality. The range of CT findings included minimal enlargement with faint flecks of calcium, moderate enlargement with focal low attenuation nodules, and massive enlargement with large areas of necrosis or dense calcification. The changes in each patient were bilateral and symmetrical. Adrenal gland shape was usually preserved. Finding of percutaneous adrenal biopsy, which was performed under CT guidance, made the diagnosis in one patient. Five of seven patients had adrenal insufficiency. It is concluded that the diagnosis of disseminated histoplasmosis should be considered in any patient who has bilateral adrenal gland enlargement and who resides in an endemic area, especially if there is evidence of adrenal insufficiency.

    Allgrove (Triple A) syndrome is a rare autosomal recessive disorder characterized by cardinal features of adrenal insufficiency due to adrenocorticotropic hormone (ACTH) resistance, achalasia, and alacrimia. It is frequently associated with neurological manifestations like polyneuropathy. Since its first description by Allgrove in 1978, approximately 100 cases have been reported in the literature. Here we report an 18-year-old boy diagnosed as having Allgrove syndrome, with ACTH resistant adrenal insufficiency, achalasia, alacrimia, and severe motor polyneuropathy. Alacrimia was the earliest feature evident at the age of 8 years. He presented with achalasia and adrenal insufficiency at 12 and 18 years respectively and developed neurological symptoms in the form of severe muscle wasting at the age of 15 years. Patients with Allgrove syndrome usually manifest adrenal insufficiency and achalasia during first decade of life. Our patient manifested adrenal insufficiency and achalasia in the second decade and manifested neurological dysfunction before adrenal dysfunction. PMID:26354489

    It has been suggested that patients with certain motility disorders may progress overtime to develop achalasia. We describe a 66 year-old woman who presented with dysphagia for solids and liquids for a period of 18 months. Her initial workup showed normal endoscopy and non-specific esophageal motility disorder on conventional manometry. Six months later, due to persistence of symptoms, the patient underwent a high resolution esophageal manometry (HREM) demonstrating jackhammer esophagus. The patient was treated with a high dose proton pump inhibitor but without resolution of her symptoms. During the last year, the patient reported repeated episodes of food regurgitation and a significant weight loss. A repeat HREM revealed type II achalasia. Multiple case reports, and only a few prospective studies have demonstrated progression from certain esophageal motility disorders to achalasia. However, this report is the first to describe a case of jackhammer esophagus progressing to type II achalasia. PMID:26717932

    Abstract To date very few studies with small sample size have compared peroral esophageal myotomy (POEM) with the current surgical standard of care, laparoscopic Heller myotomy (LHM), in terms of efficacy and safety, and no recommendations have been proposed. To investigate the efficacy and safety of POEM compared with LHM, for the treatment of achalasia. The databases of Pubmed, Medline, Cochrane, and Ovid were systematically searched between January 1, 2005 and January 31, 2015, with the medical subject headings (MeSH) and keywords “achalasia,” “POEM,” “per oral endoscopic myotomy,” and “peroral endoscopic myotomy,” “laparoscopic Heller myotomy” (LHM), “Heller myotomy.” All types of study designs including adult patients with diagnosis of achalasia were selected. Studies that did not report the comparison between endoscopic and surgical treatment, experimental studies in animal models, single case reports, technical reports, reviews, abstracts, and editorials were excluded. The total number of included patients was 486 (196 in POEM group and 290 in LHM group). There were no differences between POEM and LHM in reduction in Eckardt score (MD = −0.659, 95% CI: −1.70 to 0.38, P = 0.217), operative time (MD = −0.354, 95% CI: −1.12 to 0.41, P = 0.36), postoperative pain scores (MD = −1.86, 95% CI: −5.17 to 1.44, P = 0.268), analgesic requirements (MD = −0.74, 95% CI: −2.65 to 1.16, P = 0.445), and complications (OR = 1.11, 95% CI: 0.5–2.44, P = 0.796). Length of hospital stay was significantly lower for POEM (MD = −0.629, 95% CI: −1.256 to −0.002, P = 0.049). There was a trend toward significant reduction in symptomatic gastroesophageal reflux rate in favors of LHM compared to POEM group (OR = 1.81, 95% CI: 1.11–2.95, P = 0.017). All included studied were not randomized. Furthermore all selected studies did not report the results of follow-up longer than 1 year and

    The treatment of patients with achalasia is complex due to a considerably high recurrence rate and risk of treatment-related complications. The per-oral endoscopic myotomy (POEM) is a new endoscopic technique that combines the benefits of a minimally invasive endoscopic procedure with the efficacy of a surgical myotomy. Implementation of the POEM technique may lead to fewer complications, a lower recurrence rate and reduced costs. During the procedure, a myotomy of the circular muscle layer of the oesophagus is performed after creating a submucosal tunnel in the oesophagus. The first studies of this new technique show promising results. Experienced therapeutic endoscopists can learn to perform the POEM technique relatively easily. Further studies are needed to compare this technique with the current standard treatments and to evaluate long-term effects.

    The concept of relative adrenal insufficiency (RAI) has been originally introduced to describe a situation in which critically ill patients, without any prior risk or evidence for adrenal insufficiency, have total serum cortisol levels inadequate for the severity of patients' illness. The concept provided a framework for other disease states, in which higher than normal adrenal function could be expected, such as in chronic inflammation. An intense research in RAI field highlighted some new methodological aspects that significantly improved assessment of adrenal function in chronic illness. Measurement of salivary cortisol may provide additional information on locally available cortisol in target tissues. Low levels of dehydroepiandrosterone (DHEAS) for given age and gender were confirmed as a simple and reliable indicator of decreased adrenal function, even in subjects with normal baseline cortisol or normal corticotropin-stimulated cortisol response. Combined lower DHEAS and lower baseline cortisol levels could be an example of hypocompetence of adrenocortical function, yet clinically not apparent.

    Idiopathic achalasia is a motor disorder of the esophagus of unknown etiology caused by loss of motor neurons determining an altered motility. It may determine severe symptoms such as progressive dysphagia, regurgitations, and pulmonary aspirations. Many therapeutic options may be offered to patients with achalasia, from surgery to endoscopic treatments such as pneumatic dilation, botulinum injection, peroral endoscopic myotomy, or endoscopic stenting. Recently, temporary placement of a stent was proposed by Cheng as therapy for achalasia disorders, whereas no Western authors have dealt with it up to date. The present study reports our preliminary experience in 7 patients with achalasia treated with a temporary stent. Partially covered self-expanding metallic stents (Micro-Tech, Nanjin, China) 80 mm long and 30 mm wide were placed under fluoroscopic control and removed after 6 days. Clinical follow-up was scheduled to check endoscopic success, symptoms release, and complications. The placement and the removal of the stents were obtained in all patients without complications. Mean clinical follow-up was 19 months. Five out of 7 patients referred total symptoms release and 2 experienced significant improvement of dysphagia. The procedure was not time consuming and was safe; no mild or severe complications were registered. In conclusion, our results may suggest a possible safe and effective endoscopic alternative treatment in patients with achalasia; however, further larger studies are necessary to confirm these promising, but very preliminary, data.

    Peroral endoscopic myotomy (POEM) is the application of esophageal myotomy to the concept of natural orifice transluminal surgery (NOTES) by utilizing a submucosal tunneling method. Since the first case of POEM was performed for treating achalasia in Japan in 2008, this procedure is being more widely used by many skillful endosopists all over the world. Currently, POEM is a spotlighted, emerging treatment option for achalasia, and the indications for POEM are expanding to include long-standing, sigmoid shaped esophagus in achalasia, even previously failed endoscopic treatment or surgical myotomy, and other spastic esophageal motility disorders. Accumulating data about POEM demonstrate excellent short-term outcomes with minimal risk of major adverse events, and some existing long-term data show the efficacy of POEM to be long lasting. In this review article, we review the technical details and clinical outcomes of POEM, and discuss some considerations of POEM in special situations.

    Peroral endoscopic myotomy (POEM) was first performed in Japan in 2008 for uncomplicated achalasia. With excellent results, it was adopted by highly skilled endoscopists around the world and the indications for POEM were expanded to include advanced sigmoid achalasia, failed surgical myotomy, patients with previous endoscopic treatments and even other spastic oesophageal motility disorders. With increased uptake and performance of POEM, variations in technique and improved management of adverse events have been developed. Now, 6 years since the first case and with >3,000 procedures performed worldwide, long-term data has shown the efficacy of POEM to be long-lasting. A growing body of literature also exists pertaining to the learning curve, application of novel technologies, extended indications and physiologic changes with POEM. Ultimately, this once experimental procedure is evolving towards becoming the preferred treatment for achalasia and other spastic oesophageal motility disorders.

    Esophageal achalasia is often associated with esophageal cancer. However, in many cases, esophageal cancer tends to be found in an advanced stage, with a poor prognosis. However, early-stage cancer was detected recently due to the advances in endoscopic instruments. In those cases, it is important to facilitate successful treatment by endoscopic submucosal dissection. We analyzed a total of six cases of esophageal cancer with achalasia in four patients treated with endoscopic submucosal dissection. Three features common to all six cases had a bearing on how endoscopic submucosal dissection was performed. First, esophageal dilatation and diminished peristalsis facilitated the performance of successful endoscopic submucosal dissection. Second, the esophageal wall was thickened, primarily with muscular tissue. Third, the submucosal layer contained abundant blood vessels that made it difficult to minimize bleeding during dissection. Those findings suggest that endoscopic submucosal dissection for early esophageal cancer associated with achalasia is a safe and potentially curative procedure. It is important, therefore, to detect esophageal cancer early.

    Endoscopic ultrasonography (EUS) has been widely used for evaluating the nature of diseases of various organs. The possibility of applying EUS for esophageal motility diseases has not been well discussed despite its versatility. At present, peroral endoscopic myotomy (POEM) for esophageal achalasia and related diseases has brought new attention to esophageal diseases because POEM provides a more direct approach to the inner structures of the esophageal wall. In the present study, we discuss the clinical utility of EUS in evaluating and treating esophageal motility diseases such as esophageal achalasia and related diseases.

    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

    Emergency medicine physicians should be able to identify and treat patients whose clinical presentations, including key historical, physical examination, and laboratory findings are consistent with diagnoses of primary, secondary, and tertiary adrenal insufficiency, adrenal crisis, and pheochromocytoma. Failure to make a timely diagnosis leads to increased morbidity and mortality. As great mimickers, adrenal emergencies often present with a constellation of nonspecific signs and symptoms that can lead even the most diligent emergency physician astray. The emergency physician must include adrenal emergencies in the differential diagnosis when encountering such clinical pictures.

    Achalasia is an important but relatively uncommon disorder. While highly effective therapeutic options exist, esophageal cancer remains a long-term potential complication. The risk of esophageal cancer in achalasia remains unclear, with current guidelines recommending against routine endoscopic screening. However, given limited data and conflicting opinion, it is unknown whether consensus regarding screening practices in achalasia among experts exists. A 10-question survey to assess screening practices in achalasia was created and distributed to 28 experts in the area of achalasia. Experts were identified based on publications and meeting presentations in the field. Survey responses were received from 17 of 28 (61%) experts. Wide geographic distribution was seen among respondents, with eight (47%) from Europe or Australia, seven (41%) from the United States, and two (12%) from Asia. Screening for esophageal cancer was inconsistent, with nine (53%) experts endorsing the practice and eight (47%) not. Screening practices did not differ among geographic regions. No consensus regarding the risk for esophageal cancer in achalasia was seen, with three experts reporting no increased risk compared with the general population, eight experts a lifetime risk of 0.1-0.5%, three experts a 0.5-1% risk, two experts a 1-2% risk, and one expert a 3-5% risk. However, these differences in perception of risk did not influence screening practices. Upper endoscopy was utilized among all experts who endorsed screening. However, practices still varied with screening commencing at or within 1 year of diagnosis in two practices compared with 5 and 10 years in three respective practices each. Surveillance intervals also varied, performed every 2 years in four practices, every 3 years in four practices, and every 5 years in one practice. Practice variation in the management of achalasia itself was also seen, with initial treatment with Heller myotomy endorsed by eight experts, pneumatic

    In general, the treatment methods for esophageal achalasia are largely classified into four groups, including drug therapy using nitrite or a calcium channel blocker, botulinum toxin injection, endoscopic therapy such as endoscopic balloon dilation, and surgery. Various studies have suggested that the most effective treatment of esophageal achalasia is surgical therapy. The basic concept of this surgical therapy has not changed since Heller proposed esophageal myotomy for the purpose of resolution of lower esophageal obstruction for the first time in 1913, but the most common approach has changed from open-chest surgery to laparoscopic surgery. Currently, the laparoscopic surgery has been the procedure of choice for the treatment of esophageal achalasia. During the process of the transition from open-chest surgery to laparotomy, to thoracoscopic surgery, and to laparoscopic surgery, the necessity of combining antireflux surgery has been recognized. There is some debate as to which type of antireflux surgery should be selected. The Toupet fundoplication may be the most effective in prevention of postoperative antireflux, but many medical institutions have selected the Dor fundoplication which covers the mucosal surface exposed by myotomy. Recently, a new endoscopic approach, peroral endoscopic myotomy (POEM), has received attention. Future studies should examine the long-term outcomes and whether POEM becomes the gold standard for the treatment of esophageal achalasia.

    Achalasia is an uncommon esophageal motility disorder characterized by the selective loss of enteric neurons leading to absence of peristalsis and impaired relaxation of the lower esophageal sphincter. Per-oral endoscopic myotomy (POEM) is a novel modality for the treatment of achalasia performed by gastroenterologists and surgeons. It represents a natural orifice transluminal endoscopic surgery (NOTES) approach to Heller myotomy. POEM has the minimal invasiveness of an endoscopic procedure that can duplicate results of the surgical Heller myotomy. POEM is conceptually similar to a surgical myotomy without the inherent external incisions and post-operative care associated with surgery. Initial high success and low complications rates promise a great future for this technique. In fact, POEM has been successfully performed on patients with end-stage achalasia as an initial treatment reserving esophagectomy for those without good response. The volume of POEMs performed worldwide has grown exponentially. In fact, surgeons who have performed Heller myotomy have embraced POEM as the preferred intervention for achalasia. However, the niche of POEM remains to be defined and long term results are awaited. We describe our experience with POEM having performed the first POEM outside of Japan in 2009, the evolution of our technique, and give our perspective on its future.

    Recent advances in the treatment of achalasia include the use of high-resolution manometry to predict the outcome of patients and the introduction of peroral endoscopic myotomy (POEM). The first multicenter randomized, controlled, 2-year follow-up study conducted by the European Achalasia Trial group indicated that laparoscopic Heller myotomy (LHM) was not superior to pneumatic dilations (PD). Publications on the long-term success of laparoscopic surgery continue to emerge. In addition, laparoscopic single-site surgery is applicable to advanced laparoscopic operations such as LHM and anterior fundoplication. The optimal treatment option is an ongoing matter of debate. In this review, we provide an update of the current progress in the treatment of esophageal achalasia. Unless new conclusive data prove otherwise, LHM is considered the most durable treatment for achalasia at the expense of increased reflux-associated complications. However, PD is the first choice for non-surgical treatment and is more cost-effective. Repeated PD according to an "on-demand" strategy based on symptom recurrence can achieve long-term remission. Decision making should be based on clinical evidence that identifies a subcategory of patients who would benefit from specific treatment options. POEM has shown promise but its long-term efficacy and safety need to be assessed further.

    Achalasia is a primary disorder of esophageal motility. It classically presents with dysphagia to both solids and liquids but may be accompanied by regurgitation and chest pain. The gold standard for the diagnosis of achalasia is esophageal motility testing with manometry, which often reveals aperistalsis of the esophageal body and incomplete lower esophageal sphincter relaxation. The diagnosis is aided by complimentary tests, such as esophagogastroduodenoscopy and contrast radiography. Esophagogastroduodenoscopy is indicated to rule out mimickers of the disease known as “pseudoachalasia” (eg, malignancy). Endoscopic appearance of a dilated esophagus with retained food or saliva and a puckered lower esophageal sphincter should raise suspicion for achalasia. Additionally, barium esophagography may reveal a dilated esophagus with a distal tapering giving it a “bird’s beak” appearance. Multiple therapeutic modalities aid in the management of achalasia, the decision of which depends on operative risk factors. Conventional treatments include medical therapy, botulinum toxin injection, pneumatic dilation, and Heller myotomy. The last two are defined as the most definitive treatment options. New emerging therapies include peroral endoscopic myotomy, placement of self-expanding metallic stents, and endoscopic sclerotherapy. PMID:27110134

    The immense success of laparoscopic surgery as an effective treatment of gastroesophageal reflux disease (GERD) and achalasia has established minimal invasive surgery as the gold standard for these two conditions with lower morbidity and mortality, shorter hospital stay, faster convalescence, and less postoperative pain. One controversy in the treatment of GERD evolves around laparoscopic antireflux surgery (LARS) as the preferred treatment for Barrett’s esophagus and the procedure’s potential to reduce the risk of adenocarcinoma of the esophagus. GERD has also been associated with respiratory symptoms, asthma and laryngeal injury, and a second controversy prompts discussions about whether total or partial fundoplication is the more appropriate treatment for GERD. A new and promising alternative in the treatment of GERD is endoluminal therapy. Three types of this new treatment option will be discussed: radiofrequency energy delivered to the lower esophageal sphincter, the creation of a mechanical barrier at the gastroesophageal junction, and the direct endoscopic tightening of the lower esophageal sphincter. Laparoscopic surgery is discussed not only as a very effective treatment for GERD but also as permanent cure for achalasia. This review analyzes the three most important treatment options for achalasia: medications, pneumatic dilatation, and surgical therapy. Medications as the only true non-invasive option in the treatment of achalasia are not as effective as LARS because of their short half-life and variable absorption due to the poor esophageal emptying. The second treatment option, pneumatic dilatation, involves the stretching of the lower esophagus and is still considered the most effective non-surgical treatment for achalasia. Finally, surgical therapy for achalasia and the two major controversies concerning this laparoscopic treatment are discussed. The first involves the extent to which the myotomy is extended onto the stomach, and the second

    Achalasia is an esophageal motility disorder that is commonly misdiagnosed initially as gastroesophageal reflux disease. Patients with achalasia often complain of dysphagia with solids and liquids but may focus on regurgitation as the primary symptom, leading to initial misdiagnosis. Diagnostic tests for achalasia include esophageal motility testing, esophagogastroduodenoscopy and barium swallow. These tests play a complimentary role in establishing the diagnosis of suspected achalasia. High-resolution manometry has now identified three subtypes of achalasia, with therapeutic implications. Pneumatic dilation and surgical myotomy are the only definitive treatment options for patients with achalasia who can undergo surgery. Botulinum toxin injection into the lower esophageal sphincter should be reserved for those who cannot undergo definitive therapy. Close follow-up is paramount because many patients will have a recurrence of symptoms and require repeat treatment.

    Achalasia is a rare motility disorder of the oesophagus. Classic achalasia is characterised by a lack of propulsive peristalsis of the distal oesophagus and incomplete relaxation of the lower oesophageal sphincter (LES). Traditionally achalasia is treated either endoscopically by pneumatic balloon dilatation or laparoscopically by Heller's myotomy. Both therapeutic procedures show a comparable effectiveness. Recently, peroral endoscopic myotomy was introduced as a new definitive treatment option. So far, this minimally invasive therapy was evaluated in a few clinical studies only. In this survey, peroral endoscopic myotomy is presented and compared to the well established surgical treatment. The diagnosis of achalasia is based on the patient's medical history and analysis of symptoms and particularly on oesophageal manometry. In addition, a barium swallow (oesophagram) and upper endoscopy are performed to rule out other reasons causing dysphagia. The patient's complaints should be recorded by use of a symptoms score. The POEM procedure starts with an incision of the mucosa at the level of the mid-oesophagus. Then, a submucosal tunnel is created distally passing approximately 2 cm over the oesophagogastric junction. After this step, myotomy of (at least) the circular muscle bundle of the distal oesophagus is performed and should be extended to a distance of 2 cm over the cardiac. Finally the mucosal entry site at the level of the mid-oesophagus is closed with endoscopic clips. First results of this technique are very promising with significant symptom relief and reduction of the mean LES pressure. In conclusion, POEM is a new, minimally invasive therapeutic option for the treatment of oesophageal achalasia. First results are very promising; long-term results and results of comparative clinical trials with established treatment methods must be awaited.

  2. Longitudinal Muscle Dysfunction in Achalasia Esophagus and Its Relevance

    2013-01-01

    Muscularis propria of the esophagus is organized into circular and longitudinal muscle layers. Goal of this review is to summarize the role of longitudinal muscle in physiology and pathophysiology of esophageal sensory and motor function. Simultaneous manometry and ultrasound imaging that measure circular and longitudinal muscle contraction respectively reveal that during peristalsis 2 layers of the esophagus contract in perfect synchrony. On the other hand, during transient relaxation of the lower esophageal sphincter (LES), longitudinal muscle contracts independently of circular muscle. Recent studies provide novel insights, i.e., longitudinal muscle contraction of the esophagus induces LES relaxation and possibly descending relaxation of the esophagus. In achalasia esophagus and other motility disorders there is discoordination between the 2 muscle layers. Longitudinal muscle contraction patterns are different in the recently described three types of achalasia identified by high-resolution manometry. Robust contraction of the longitudinal muscle in type II achalasia causes pan-esophageal pressurization and is the mechanism of whatever little esophageal emptying that take place in the absence of peristalsis and impaired LES relaxation. It may be that preserved longitudinal muscle contraction is also the reason for superior outcome to medical/surgical therapy in type II achalasia esophagus. Prolonged contractions of longitudinal muscles of the esophagus is a possible mechanism of heartburn and "angina like" pain seen in esophageal motility disorders and possibly achalasia esophagus. Novel techniques to record longitudinal muscle contraction are on the horizon. Neuro-pharmacologic control of circular and longitudinal muscles is different, which provides an important opportunity for the development of novel pharmacological therapies to treat sensory and motor disorders of the esophagus.

The syntheses of mineralocorticoids, glucocorticoids and adrenal androgens occur in separate adrenal cortical zones, each expressing specific enzymes. Congenital adrenal hyperplasia (CAH) encompasses a group of autosomal recessive enzymatic defects in cortisol biosynthesis. 21-hydroxylase (21OHD) deficiency accounts for over 90% of CAH cases and when milder or nonclassic forms are included, 21OHD is one of the most common genetic diseases. This review discusses in detail the epidemiology, genetics, diagnostic, clinical aspects and management of 21OHD. PMID:26038201

An 18-year-old-male with HSMN with sensorineural deafness presented with a 2-day history of dysphagia to solids and liquids. Achalasia was diagnosed after extensive investigations, and his symptoms resolved with endoscopic and definitive surgical management. His monozygotic twin brother had also been diagnosed with HSMN and suffered from chronic dysphagia, which was also subsequently diagnosed with achalasia. This is the first case to illustrate an association between HSMN with sensorineural deafness and achalasia.

    Adrenal insufficiency is a rare but life-threatening disease. Replacement therapy sometimes fails to prevent an acute adrenal crisis and most often does not lead to restoration of well-being. We report here the 1-year outcome of the first simultaneous kidney-adrenal gland-pancreas transplantation in a 33-year-old patient with type 1 diabetes and concomitant autoimmune adrenal insufficiency. En bloc left adrenal gland and kidney grafts were anastomosed on the left iliac vessels in normal vascular conditions and the pancreas graft was anastomosed on the right iliac vessels. The immunosuppressive regimen was not modified by the addition of the adrenal gland. We observed no additional morbidity due to the adrenal gland transplantation, as there were no surgical complications. One-year kidney and pancreas graft functions were satisfactory (estimated glomerular filtration rate: 55 mL/min/1.73 m(2) and HbA1c: 4.8%). The adrenal graft functioned well at 12 months with a normalization of cortisol and aldosterone baseline levels. Functional imaging at 3 months showed good uptake of [(123) I]-metaiodobenzylguanidine by the adrenal graft. Transplantation of the adrenal gland en bloc with the left kidney appears to be a good therapeutic option in patients with adrenal insufficiency awaiting kidney or kidney-pancreas transplantation.

    Per-oral endoscopic myotomy (POEM) is a new minimally invasive endoscopic treatment for achalasia. Since the first modern human cases were published in 2008, around 2,000 cases have been performed worldwide. This technique requires advanced endoscopic skills and a learning curve of at least 20 cases. POEM is highly successful with over 90 % improvement in dysphagia while offering patients the advantage of a low impact endoscopic access. The main long-term complication is gastroesophageal reflux (GER) with an estimated incidence of 35 %, similar to the incidence of GER post-laparoscopic Heller with fundoplication. Although POEM represents a paradigm shift in the treatment of achalasia, more long-term data are clearly needed to further define its role in the treatment algorithm of this rare disease.

This remarkable change is due to the recognition by gastroenterologists and patients that a laparoscopic Heller myotomy outperforms pneumatic dilatation and intra-sphincteric injection of botulinum toxin injection. While there is agreement about the technique of the myotomy per se, some questions still linger about the need for a fundoplication after the myotomy. The following review describes the data present in the literature in order to identify the best procedure that can achieve relief of dysphagia while avoiding development of gastroesophageal reflux.

    Hypoplasia adrenal congenita is an extremely uncommon disease of early onset. This condition can be lethal in the absence of treatment. Some forms are due to the congenital adrenal hypoplasia of anencephalic type whose origin is even unknown. Here, we present two cases of congenital adrenal hypoplasia of anencephalic type with pituitary abnormalities. The two male newborns died because adrenal insufficiency in the neonatal period. The adrenal glands were hypoplastic with a histological structure of anencephalic type Immunocytochemical study of the pituitary revealed an absence of the gonadotrophs. No mutation of DAX 1 and SF-1 was found.

    Pneumomediastinum is usually first identified radiographically in the emergency department. Distinguishing benign from more ominous causes, such as esophageal rupture, is imperative, particularly in the setting of associated esophageal disease. We describe a case, with correlative imaging, of spontaneous pneumomediastinum as the initial presentation of achalasia. A general discussion of spontaneous pneumomediastinum is also provided, including the pathophysiology, precipitating and predisposing factors, clinical manifestations, role of radiology in the diagnosis as well as the radiographic signs.

    Background/Aims Achalasia cardia (AC) is a motility disorder, characterized by impaired lower esophageal sphincter relaxation and absence of esophageal peristalsis. AC is rare in children with unclear optimum management strategies. Per oral endoscopic myotomy (POEM) is a novel technique for management of achalasia with encouraging results in adult patients. The efficacy and safety of POEM is not known for pediatric AC. The aim of our study was to evaluate the safety and efficacy of POEM in children with achalasia cardia Methods The data of all children (< 18 years) who underwent POEM at our center was retrospectively analysed. Symptoms were analysed using a validated score (Eckardt score) at regular predefined intervals. Objective parameters including high-resolution manometry, timed barium swallow and esophagogastroduodenoscopy were assessed before the procedure and at 1-year follow-up. Clinical success was defined as an Eckardt score ≤ 3. Results A total of 15 children underwent POEM during the specified period. Ten out of 15 (10/15) completed 1-year follow-up. Median operative time was 100 (38–240) minutes. Mean pre and post procedure LES pressure were 36.64 ± 11.08 mmHg and 15.65 ± 5.73 mmHg, respectively (P = 0.001). Mean Eckardt score before and after the POEM was 7.32 ± 1.42 and 1.74 ± 0.67, respectively (P = 0.001). Mean percentage improvement in barium emptying at 5 minutes was 63.70 ± 4.46%. All children had complete resolution of symptoms at 1 year. Median weight gain of children at 1 year was 0.65 kg (range, 0.0–4.6). Conclusions POEM is safe and effective for children and adolescents with achalasia. Future trials with larger sample size are warranted to establish its efficacy in pediatric AC. PMID:27048658

    Peroral endoscopic myotomy (POEM) has been developed in the context of natural orifice transluminal endoscopic surgery (NOTES) as a minimally invasive endoscopic treatment for symptomatic esophageal achalasia, which is a chronic progressive benign disease with severe morbidity and difficult management. Since September 2008, POEM has been successfully performed in more than 200 consecutive patients with symptomatic achalasia at the Digestive Disease Center of Showa University, Northern Yokohama Hospital, Yokohama, Japan, with excellent short- and long-term results and absence of serious complications. International experience of POEM within clinical studies is also promising. According to these results, POEM is considered as a safe procedure that can be applied to all achalasia patients. However, the low incidence of achalasia (0.3%-1% per 100,000 population), in combination with the potential serious complications related to the technically demanding POEM procedure, has made training difficult. There is therefore an urgent need for an animal model for training to decrease the learning curve. Further, there are other ethical and training issues to address. The pig is the most appropriate animal model for training in POEM due to its anatomy being similar to that of humans. The porcine esophagus has the advantage of easy mobilization due to absence of tight junctions to surrounding organs. A non-survival porcine model would be a simple, inexpensive, and reproducible animal model for training in POEM, without the need for concern about complications. A possible training process might first involve observation of POEM performed by specialists, then training on non-survival and survival porcine models, followed by training in humans under specialist guidance and finally, performance of POEM in humans.

    L'achalasia is the best known primary motor disorder of the esophagus in which the lower esophageal sphincter (LES) has abnormally high resting pressure and incomplete relaxation with swallowing. Pneumatic dilatation (PD) remains the first choice of treatment. Our aim was to report, in a retrospective way, our experience in treating with pneumatic dilatation 41 achalasia patients admitted to the gastroenterology unit at Hôtel-Dieu de France (HDF) hospital between 1994 and 2004. A total of 46 dilatations were performed in 41 patients with achalasia [20 males and 21 females, the mean age was 46.8 years (range, 15-90)]. All patients underwent an initial dilatation by inflating a 35 mm balloon to 7 psi three times successively under fluoroscopic control. The need for subsequent dilatation with the same technique or for surgical treatment was based on symptom assessment. The mean follow-up period was 36.7 months (3 mo-7 years). Among the patients whose follow-up information was available, a satisfactory result was achieved in 29 patients (80.5%) after only one or two sessions of pneumatic dilatation. Esophageal perforation as a short-term complication was observed in one patient (2.17%). Seven patients were referred for surgery (one for esophageal perforation and six for persistent or recurrent symptoms). In conclusion, performing balloon dilatation under fluoroscopic observation is simple, safe and efficacious for treating patients with achalasia. Referral to repeated PD or to surgical myotomy should be discussed in case of no response to a first session of PD.

    Esophageal achalasia is a primary motility disorder characterized by impaired lower esophageal sphincter relaxation and absence of esophageal peristalsis leading to impaired bolus transit, manifested with symptoms such as dysphagia, regurgitation, retrosternal pain, and weight loss. The standard diagnostic tool is esophageal manometry which demonstrates incomplete relaxation of the lower esophageal sphincter and impaired esophageal peristalsis. Recently, a new advanced technique, high-resolution manometry (HRM) with the addition of pressure topography plotting, using multiple sensors to capture the manometric data as a spatial continuum, allows a detailed pressure recording of the esophageal motility. This technique, currently the gold standard for the diagnosis of achalasia, has led to a subclassification of three manometric types that seem to have different responsiveness to treatment. Because its pathogenesis is as yet unknown, achalasia treatment options are not curative. Type II achalasia patients respond better to treatment compared to those with types I and III. Low-risk patients with type I or II achalasia have good outcome with both graded pneumatic dilatations and laparoscopic Heller myotomy, while type III achalasia patients respond better to laparoscopic Heller myotomy. Although, type III achalasia patients responds less in comparison to types I and II to laparoscopic Heller myotomy. Peroral endoscopic myotomy is a promising new technique but long-term follow-up studies for its safety and efficacy must be performed. This article reviews the current therapeutic options, highlighting the impact of HRM to predict the outcome and the new insights for the treatment of achalasia. PMID:26130022

    Achalasia is a rare esophagus motility disorder. Medical, endoscopic and surgical treatments are available, but all endorse high relapse rates. No data has been published to date reporting a therapeutic effect of cannabis use neither in achalasia nor on its influence on manometric measurements. We report the case of a patient diagnosed with achalasia. He could benefit from a large panel of therapeutic interventions, but none of them was effective over the time. He first used cannabis at age 20 and identified benefits regarding achalasia symptoms. He maintained regular moderate cannabis use for 9 years, with minimal digestive inconvenience. A manometry performed without cannabis premedication was realized at age 26 and still found a cardiospasm. Cannabis use could explain the gap between functional symptoms assessment and manometry measurement. Further investigations are warranted to explore a therapeutic effect of cannabis in achalasia and possible influence on outcome measurements. PMID:26034374

  1. Is DHEA replacement beneficial in chronic adrenal failure?

    2015-01-01

    Although dehydroepiandrosterone (DHEA) and its sulphate ester dehydroepiandrosterone sulphate (DHEAS) are the most abundant steroid hormones in the human circulation, its exact physiological role is not yet fully understood. In patients with adrenal insufficiency, secretion of DHEA is impaired, leading to decreased circulating DHEA and DHEAS levels, and to androgen deficiency in women. Replacement of DHEA in patients with adrenal insufficiency positively influence mood, sexuality and subjective health status. These effects are generally moderate and show high inter-individual variability. Limited evidence exists for immunomodulatory effects of DHEA. Although an increase of IGF-I levels has been documented, relevant effects on body composition, metabolic or cardiovascular parameters has not been observed in patients with adrenal insufficiency receiving DHEA. Larger-scale phase III studies are still lacking; therefore, initiation of DHEA replacement is decided on an individual basis, focussing on those patients with impaired well-being associated with signs and symptoms of androgen deficiency.

    Previous studies have correlated esophageal body motility findings in idiopathic (IdAc) achalasia and achalasia secondary to Chagas' disease (ChAc) with degree of megaesophagus. The aim of this study was to compare esophageal body manometric data in patients with IdAc and achalasia secondary to Chagas' disease and correlate it with the degree of megaesophagus and symptom duration. One hundred nontreated patients with achalasia, 79% IdAc and 21% secondary to ChAc were compared with regards to age of presentation, duration of symptoms, amplitude and duration of simultaneous contractions, frequency of failed contractions, and degree of megaesophagus. Seventy-one percent of patients were classified as nonadvanced megaesophagus (60 [76%] with IdAc and 11 [52%] with ChAc) and 29% as advanced megaesophagus (19 [24%] with IdAc and 10 [48%] with ChAc, P= 0.04). In IdAc but not in ChAc, the symptom duration was significantly longer in advanced megaesophagus (A) compared with nonadvanced megaesophagus (NA) (34.8 ± 6.3 months vs. 95.4 ± 22.2 months, P= 0.001). There was no difference in amplitude and duration of simultaneous contractions in both achalasia groups (P > 0.05). Duration of contractions were longer in IdAc compared with ChAc in (NA) (P < 0.05), but not in (A). In IdAc but not in ChAc the amplitude of simultaneous contractions decreased with increased esophageal dilatation (P < 0.05). In ChAc but not in IdAC, the duration of contractions increased with esophageal dilatation (P < 0.05). Failed contractions were more frequent in ChAc group (28.6%) than in IdAc (10% -P= 0.03). Patients with ChAc have a higher prevalence of advanced megaesophagus compared with IdAc at diagnosis. In IdAc there was a strong correlation between advanced megaesophagus and longer symptom duration, suggesting disease progression over time, not observed in ChAc in which a more extensive denervation occurs earlier in the disease process.

    In this report, images of intense adrenal enhancement in a 79-year-old female patient with right-sided heart failure and severe tricuspid insufficiency are presented. Only two cases of intense adrenal enhancement as a sign of cardiogenic shock were previously reported in the literature. Intense adrenal enhancement could be one of the earliest CT signs of cardiogenic shock. Its presence should be immediately reported to the referring physician as a sign of significant hemodynamic instability warranting early critical-care management.

    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.

    The adrenal glands of 30 dogs with primary adrenal insufficiency (hypoadrenocorticism) were measured ultrasonographically and compared with those of 14 healthy dogs and those of 10 dogs with diseases mimicking hypoadrenocorticism. Thickness and length of the adrenals were measured on abdominal ultrasonography and the results for each group were compared. Dogs with primary hypoadrenocorticism had significantly thinner adrenals compared with the other two groups, and their left adrenal glands were also significantly shorter than those of healthy dogs. Adrenal ultrasonography may be of diagnostic value in dogs with clinical signs suggestive of primary hypoadrenocorticism, as a left adrenal gland measuring less than 3.2 mm in thickness is strongly suggestive of the disease.

    Background & Aims The functional lumen imaging probe (FLIP) could improve characterization of achalasia subtypes by detecting non-occlusive esophageal contractions not observed with standard manometry. We aimed to evaluate for esophageal contractions during volumetric distention in patients with achalasia using FLIP topography. Methods Fifty one treatment-naïve patients with achalasia, defined and sub-classified by high-resolution esophageal pressure topography, and 10 asymptomatic individuals (controls) were evaluated with the FLIP during endoscopy. During stepwise distension, simultaneous intra-bag pressures and 16 channels of cross-sectional areas were measured; data were exported to software that generated FLIP topography plots. Esophageal contractility was identified by noting periods of reduced luminal diameter. Esophageal contractions were further characterized by propagation direction, repetitiveness, and based on whether they were occluding or non-occluding. Results Esophageal contractility was detected in all 10 controls: 8/10 had repetitive, antegrade, contractions and 9/10 had occluding contractions. Contractility was detected in 27% (4/15) of patients with type I achalasia and 65% (18/26, including 9 with occluding contractions) of patients with type II achalasia. Contractility was detected in all 10 patients with type III achalasia; 8 of these patients had a pattern of contractility not observed in controls (repetitive, retrograde contractions). Conclusions Esophageal contractility not observed with manometry can be detected in patients with achalasia using FLIP topography. The presence and patterns of contractility detected with FLIP topography may represent variations in pathophysiology, such as mechanisms of pan-esophageal pressurization in patients with type II achalasia. These findings could have implications for additional sub-classification to supplement prediction of the achalasia disease course. PMID:26278501

    2013-01-01

    High-resolution manometry and recently described analysis algorithms, summarized in the Chicago Classification, have increased the recognition of achalasia. It has become apparent that the cardinal feature of achalasia, impaired lower esophageal sphincter relaxation, can occur in several disease phenotypes: without peristalsis, with premature (spastic) distal esophageal contractions, with panesophageal pressurization, or with peristalsis. Any of these phenotypes could indicate achalasia; however, without a disease-specific biomarker, no manometric pattern is absolutely specific. Laboratory studies indicate that achalasia is an autoimmune disease in which esophageal myenteric neurons are attacked in a cell-mediated and antibody-mediated immune response against an uncertain antigen. This autoimmune response could be related to infection of genetically predisposed subjects with herpes simplex virus 1, although there is substantial heterogeneity among patients. At one end of the spectrum is complete aganglionosis in patients with end-stage or fulminant disease. At the opposite extreme is type III (spastic) achalasia, which has no demonstrated neuronal loss but only impaired inhibitory postganglionic neuron function; it is often associated with accentuated contractility and could be mediated by cytokine-induced alterations in gene expression. Distinct from these extremes is progressive plexopathy, which likely arises from achalasia with preserved peristalsis and then develops into type II achalasia and then type I achalasia. Variations in its extent and rate of progression are likely related to the intensity of the cytotoxic T-cell assault on the myenteric plexus. Moving forward, we need to integrate the knowledge we have gained into treatment paradigms that are specific for individual phenotypes of achalasia and away from the one-size-fits-all approach.

    The adrenal gland is an essential endocrine organ for the stress response. The functions of this organ may be studied by ligation of the adrenal artery or adrenalectomy. However, in prior studies, descriptions of the anatomical variations of the adrenal artery were insufficient and inconsistent. Therefore, anatomical variations of the arterial supply to the adrenal gland were studied in 18 male and 18 female Wistar rats by colored latex injection into the arteries. The vascularization pattern was categorized into 4 types based on the origin of each adrenal artery. The cranial and middle adrenal arteries arose from the caudal phrenic artery in Types 1–3, but the caudal adrenal artery emerged from the caudal phrenic artery in Type 1, from the renal artery in Type 2 and from the abdominal aorta in Type 3. In Type 4, the cranial and middle adrenal arteries stemmed from the cranial phrenic artery, and the caudal adrenal artery arose from the caudal phrenic artery. The number of adrenal arteries varied from 3 to 11 on the left side and from 4 to 12 on the right side, and the total varied from 9 to 20 (predominantly 14) in each individual. There was no sex difference in the vascularization pattern. The results show that more individual variations occur in the adrenal arteries of rats than was previously reported. Such variations should always be considered when experimental treatments of the rat adrenal gland are performed. PMID:27867163

    Alcohol and tobacco abuse are the main risk factors for esophageal squamous cell carcinoma (ESCC), but other conditions that induce chronic irritation of the esophageal mucosa have also been attributed to it. For example, long-standing achalasia increases 16 times the risk of developing ESCC. We report the case of a patient with long-standing achalasia who developed ESCC. Although this complication is infrequent, it should be remembered by clinicians who treat patients with achalasia to detect early stages cancer. PMID:25564630

In this prospective 10-year follow-up study, a satisfactory therapeutic effect was achieved without serious complications. We report the therapeutic experience with pneumatic dilation, having aimed to evaluate the long-term clinical safety and efficacy of pneumatic dilation. In total, 35 consecutive patients with idiopathic achalasia who underwent pneumatic dilation were followed up at regular intervals in person or by a phone interview over a 10-year period. The mean duration of the follow-up was 43.03 ± 26.34 months (range 6-120 months). Remission was assessed by the dysphagia classification and symptom scores. Patients' clinical symptom scores were calculated before and at 6 to 36  months, 37 to 60  months, and >60  months after therapy. The influence of the patients' age, gender, and disease duration on the therapeutic effect was analyzed. The success rate of the operation was 97.2% (35/36), without massive hemorrhaging, perforation or other serious complications. Dysphagia after the therapy was significantly eased (P < 0.01). In total, 35 patients have been followed up for 6 to 36  months after therapy, 21 cases for 37 to 60  months, and 5 cases for >60  months, and the patients' symptom scores separately decreased significantly compared with the pretherapy scores (P < 0.01).

  13. Hypertension and adrenal disorders.

    PubMed

    Abnormalities of adrenal cortical and medullary function are important causes of hypertension in adults. Mineralocorticoid hypertension, characterized by spontaneous hypokalemia with excessive kaliuresis and low plasma renin activity, is most commonly caused by aldosterone-producing adenoma or, less frequently, by nonadenomatous adrenal hyperplasia. However, recent evidence indicates that this classification oversimplifies the pathophysiologic diversity of this syndrome. Advances in steroid biochemistry and molecular biology have improved our ability to identify patients with various forms of mineralocorticoid hypertension and also provide evidence that they are underdiagnosed. Pheochromocytomas are most commonly located in the adrenal medulla, where they may overproduce norepinephrine or epinephrine. Appropriate screening of norepinephrine, epinephrine, and their metabolites is essential because tumors that secrete epinephrine exclusively may not present with hypertension and, thus, can be overlooked. Extra-adrenal pheochromocytomas are more prevalent than previously considered and pose special problems because they may be multicentric, difficult to locate, and more likely to be malignant than are adrenal pheochromocytomas.

    Peroral endoscopic myotomy (POEM) is an emerging minimally invasive procedure for the treatment of achalasia. Due to the improvements in endoscopic technology and techniques, this procedure allows for submucosal tunneling to safely endoscopically create a myotomy across the hypertensive lower esophageal sphincter. In the hands of skilled operators and experienced centers, the most common complications of this procedure are related to insufflation and accumulation of gas in the chest and abdominal cavities with relatively low risks of devastating complications such as perforation or delayed bleeding. Several centers worldwide have demonstrated the feasibility of this procedure in not only early achalasia but also other indications such as redo myotomy, sigmoid esophagus and spastic esophagus. Short-term outcomes have showed great clinical efficacy comparable to laparoscopic Heller myotomy (LHM). Concerns related to postoperative gastroesophageal reflux remain, however several groups have demonstrated comparable clinical and objective measures of reflux to LHM. Although long-term outcomes are necessary to better understand durability of the procedure, POEM appears to be a promising new procedure.

    Achalasia is an oesophageal motor disorder which leads to the functional obstruction of the lower oesophageal sphincter (LES) and is currently incurable. The main objective of all existing therapies is to achieve a reduction in the obstruction of the distal oesophagus in order to improve oesophageal transit, relieve the symptomatology, and prevent long-term complications. The most common treatments used are pneumatic dilation (PD) and laparoscopic Heller myotomy, which involves partial fundoplication with comparable short-term success rates. The most economic non-surgical therapy is PD, with botulinum toxin injections reserved for patients with a higher surgical risk for whom the former treatment option is unsuitable. A new technology is peroral endoscopic myotomy, postulated as a possible non-invasive alternative to surgical myotomy. Other endoluminal treatments subject to research more recently include injecting ethanolamine into the LES and using a temporary self-expanding metallic stent. At present, there is not enough evidence permitting a routine recommendation of any of these three novel methods. Patients must undergo follow-up after treatment to guarantee that their symptoms are under control and to prevent complications. Most experts are in favour of some form of endoscopic follow-up, however no established guidelines exist in this respect. The prognosis for patients with achalasia is good, although a recurrence after treatment using any method requires new treatment. PMID:26078828

  16. Pharmacotherapy for the management of achalasia: Current status, challenges and future directions

    This article reviews currently available pharmacological options available for the treatment of achalasia, with a special focus on the role of botulinum toxin (BT) injection due to its superior therapeutic effect and side effect profile. The discussion on BT includes the role of different BT serotypes, better pharmacological formulations, improved BT injection techniques, the use of sprouting inhibitors, designer recombinant BT formulations and alternative substances used in endoscopic injections. The large body of ongoing research into achalasia and BT may provide a stronger role for BT injection as a form of minimally invasive, cost effective and efficacious form of therapy for patients with achalasia. The article also explores current issues and future research avenues that may prove beneficial in improving the efficacy of pharmacological treatment approaches in patients with achalasia.

    Nitric oxide is thought to have a role in the pathogenesis of achalasia. We performed a genetic analysis of 2 siblings with infant-onset achalasia. Exome analysis revealed that they were homozygous for a premature stop codon in the gene encoding nitric oxide synthase 1. Kinetic analyses and molecular modeling showed that the truncated protein product has defects in folding, nitric oxide production, and binding of cofactors. Heller myotomy had no effect in these patients, but sildenafil therapy increased their ability to drink. The finding recapitulates the previously reported phenotype of nitric oxide synthase 1-deficient mice, which have achalasia. Nitric oxide signaling appears to be involved in the pathogenesis of achalasia in humans.

    AIM: To evaluate the association between various lifestyle factors and achalasia risk. METHODS: A population-based case-control study was conducted in Northern Ireland, including n = 151 achalasia cases and n = 117 age- and sex-matched controls. Lifestyle factors were assessed via a face-to-face structured interview. The association between achalasia and lifestyle factors was assessed by unconditional logistic regression, to produce odds ratios (OR) and 95% confidence interval (CI). RESULTS: Individuals who had low-class occupations were at the highest risk of achalasia (OR = 1.88, 95%CI: 1.02-3.45), inferring that high-class occupation holders have a reduced risk of achalasia. A history of foreign travel, a lifestyle factor linked to upper socio-economic class, was also associated with a reduced risk of achalasia (OR = 0.59, 95%CI: 0.35-0.99). Smoking and alcohol consumption carried significantly reduced risks of achalasia, even after adjustment for socio-economic status. The presence of pets in the house was associated with a two-fold increased risk of achalasia (OR = 2.00, 95%CI: 1.17-3.42). No childhood household factors were associated with achalasia risk. CONCLUSION: Achalasia is a disease of inequality, and individuals from low socio-economic backgrounds are at highest risk. This does not appear to be due to corresponding alcohol and smoking behaviours. An observed positive association between pet ownership and achalasia risk suggests an interaction between endotoxin and viral infection exposure in achalasia aetiology. PMID:27099443

    An adrenal mass can be either symptomatic or asymptomatic in the form of adrenal incidentalomas (AIs) in up to 8 % in autopsy and 4 % in imaging series. Once a diagnosis of adrenal mass is made, we need to differentiate whether it is functioning or nonfunctioning, benign, or malignant. In this article, we provide a literature review of the diagnostic workup including biochemical evaluation and imaging characteristics of the different pathologies. We also discuss the surgical strategies with laparoscopy as the mainstay with partial adrenalectomy in select cases and adrenalectomy in large masses. Follow-up protocol of AIs and adrenocortical carcinoma is also discussed.

    We report a patient who developed subacute facial-predominant numbness and anhidrosis, oral incoordination, and esophageal achalasia with resultant cachexia. Great auricular nerve biopsy showed extensive epineurial perivascular inflammatory infiltrates. Sensation, sweating, and swallowing improved with pulse intravenous methylprednisolone given over 5 years. We suggest that the patient's deficits, including achalasia, were due to an immune-mediated sensory and autonomic neuropathy and that, in such cases, pathologic studies of the great auricular nerve may be diagnostically informative.

    The etiology of achalasia remains largely unknown. Considerable evidence reveals that the lower esophageal sphincter dysfunction is due to the lack of inhibitory neurotransmitter, secondary to esophageal neuronal inflammation or loss. Recent studies suggest hydrogen sulfide may act as an inhibitory transmitter in gastrointestinal tract, but study about hydrogen sulfide in human esophagus still lack. The aim of the study was to investigate if hydrogen sulfide synthesis enzymes could be detected in human esophagus and if the synthesis of the endogenous hydrogen sulfide could be affected in achalasia patients. Tissue samples in cardia, lower esophageal sphincter, 2 cm and 4 cm above lower esophageal sphincter were obtained from achalasia patients undergoing peroral endoscopic myotomy. Control tissues in lower esophageal sphincter were obtained from esophageal carcinoma patients. Expression of cystathionine-β-synthase and cystathionine-γ-lyase in lower esophageal sphincter of achalasia patients and control were detected by immunohistochemical staining. In addition, expression of cystathionine-β-synthase and cystathionine-γ-lyase were compared among different parts of esophagus in achalasia patients. Compared with control, the expression of cystathionine-β-synthase and cystathionine-γ-lyase in lower esophageal sphincter of achalasia patients was significantly reduced (χ(2) = 11.429, P = 0.010). The expression of cystathionine-β-synthase and cystathionine-γ-lyase were lower in lower esophageal sphincter than that in 2 cm and 4 cm above lower esophageal sphincter, respectively (all P < 0.05). In conclusion, the expression of hydrogen sulfide synthesis enzymes, cystathionine-β-synthase and cystathionine-γ-lyase, can be detected in human esophagus and is reduced in patients with achalasia, which implicates the involvement of the two hydrogen sulfide synthesis enzymes in the pathophysiology of achalasia.

    Heparin-induced thrombocytopaenia (HIT) is a life-threatening complication of exposure to heparin. It is mediated by autoantibodies to platelet factor-4 causing platelet activation, destruction and thrombosis. Given their rich arterial supply and a single central vein, the adrenal glands are particularly susceptible to congestive haemorrhage following venous thrombosis. We report a case of bilateral adrenal haemorrhage (BAH) associated with HIT following prophylactic use of unfractionated heparin for venous thromboembolism causing adrenal insufficiency. BAH is a life-threatening paradoxical complication associated with HIT, a prothrombotic state. The resulting adrenal insufficiency can lead to haemodynamic collapse if unrecognised. Early diagnosis, in the wake of vague symptoms, and prompt treatment primarily aimed at repletion of glucocorticoids and close monitoring of enlarging haemorrhage is of utmost importance. Likewise, early identification of HIT is important to prevent potential complications including adrenal haemorrhage.

    Achalasia is an esophageal motility disorder of unknown etiology. Several studies suggest possible herpes or measles virus etiology, but results are inconclusive. The aim of this study was to test whether herpesvirus (HV), measles (MV), or human papilloma virus (HPV) sequences could be detected in myotomy specimens from a wide spectrum of achalasia patients, using the polymerase chain reaction (PCR) technique. Myotomy specimens from 13 achalasia patients, esophagectomy specimens from nine esophageal cancer patients, and autopsy specimens from six fetuses were studied with the PCR technique. Paired oligonucleotide primers of HV (HSV-1 and 2, CMV, EBV, VZV, and HHV-6), MV and HPV sequences and exon 3 of the HPRT gene were used for the PCR DNA amplification. Amplified products were resolved on agarose gels and stained with ethidium bromide. All specimens yielded the appropriate-sized products for exon 3 of the HPRT and viral controls. No amplified products were seen in the achalasia specimens or controls corresponding to any of the virus sequences tested. The absence of HV, MV, and HPV sequences suggests that these viruses are not associated with achalasia but does not exclude the possibility of a previously unidentified virus as a causal agent. Further studies aimed at identifying an unknown viral agent as a cause for achalasia are warranted.

    Botulinum toxin injection is an accepted treatment modality for esophageal achalasia in western countries. This pilot study aimed to clarify the effectiveness of botulinum toxin injection for esophageal achalasia in Japanese patients. We enrolled 10 patients diagnosed with esophageal achalasia between 2008 and 2014. A total of 100 U botulinum toxin A was divided into eight aliquots and injected around the esophagogastric junction. We compared the lower esophageal sphincter pressure before and 1 week after treatment. Scores of subjective symptoms for esophageal achalasia were assessed using a visual analog scale (VAS) before and after 1 week of follow-up of treatment. Barium passage was improved in barium esophagography and passage of contrast agent was also improved. Mean Eckardt score was reduced from 5.5 to 1.6 after treatment (p<0.001). By esophageal manometric study, mean lower esophageal sphincter pressure was reduced from 46.9 to 29.1 mmHg after treatment (p = 0.002). One week after treatment, mean VAS score was reduced from 10 to 3.9 (p<0.001). There were no side effects in any cases. Botulinum toxin injection for esophageal achalasia was safe and effective with few complications. Therefore, botulinum toxin could be used as minimally invasive therapy for esophageal achalasia in Japan.

    Chronic gastrointestinal symptoms are commonly reported in autistic patients. Dysphagia is often present, and it is generally related to behavioral eating disorders. The association between autism and esophageal achalasia has not been described in literature yet. We report our experience with three cases of autistic children we recently treated for esophageal achalasia. In the first case (a 14-year-old male), achalasia was diagnosed with barium swallow and esophageal manometry and was successfully treated with three pneumatic endoscopic dilatations (follow-up: 3 years). In the second case (a 12-year-old female), achalasia was diagnosed with barium swallow and esophageal manometry and was treated with Heller myotomy after two unsuccessful pneumatic endoscopic attempts (follow-up: 3 months). In the last case, a 15-year-old male underwent barium swallow and endoscopy that confirmed achalasia. He was treated with Heller myotomy, and he is asymptomatic at a 6-month follow-up. To our knowledge, this is the first report of a possible association between autism and esophageal achalasia. Because of the rarity of both diseases, their association in the same patient is unlikely to be casual even if speculation on their common etiology is impossible at present. This finding needs further confirmation, but it is sufficient, in our opinion, to indicate proper evaluation with barium swallow and/or manometry in any autistic children with eating difficulty.

  11. Adrenal gland and bone.

    PubMed

    Hardy, Rowan; Cooper, Mark S

    2010-11-01

    The adrenal gland synthesizes steroid hormones from the adrenal cortex and catecholamines from the adrenal medulla. Both cortisol and adrenal androgens can have powerful effects on bone. The overproduction of cortisol in Cushing's disease leads to a dramatic reduction in bone density and an increase risk of fracture. Overproduction of adrenal androgens in congenital adrenal hyperplasia (CAH) leads to marked changes in bone growth and development with early growth acceleration but ultimately a significant reduction in final adult height. The role of more physiological levels of glucocorticoids and androgens on bone metabolism is less clear. Cortisol levels measured in elderly individuals show a weak correlation with measures of bone density and change in bone density over time with a high cortisol level associated with lower bone density and more rapid bone loss. Cortisol levels and the dynamics of cortisol secretion change with age which could also explain some age related changes in bone physiology. It is also now clear that adrenal steroids can be metabolized within bone tissue itself. Local synthesis of cortisol within bone from its inactive precursor cortisone has been demonstrated and the amount of cortisol produced within osteoblasts appears to increase with age. With regard to adrenal androgens there is a dramatic reduction in levels with aging and several studies have examined the impact that restoration of these levels back to those seen in younger individuals has on bone health. Most of these studies show small positive effects in women, not men, but the skeletal sites where benefits are seen varies from study to study.

    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) (P<0.001). The presenting symptoms for pheochromocytoma were hyperadrenergic spells (54%) and abdominal pain (29%), whereas tuberculosis presented with adrenal insufficiency (AI) (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.

    At Digestive Disease Week (DDW) 2014, developments in esophageal disease were presented. Highlights include: the usefulness of impedancemetry to diagnose reflux disease, or the effectiveness of PPIs for treating non-cardiac chest pain. Concerning Barrett's esophagus, its prevalence is identical in patients with and without reflux symptoms, Barrett segments less than 1cm probably do not require follow-up, and in older patients with long-segment Barrett, initial endoscopies overlooked up to 2% of significant lesions. Regarding achalasia, surgical myotomy is no more effective than endoscopic dilation and may even be less effective than peroral endoscopic myotomy (POEM). In terms of eosinophilic esophagitis, it is important to systematically take biopsies in patients with dysphagia so that cases of eosinophilic esophagitis are not overlooked. In addition, for this condition, routine endoscopic dilations not only do not seem useful in improving the course of the disease, but could also worsen the response to medical treatment.

    Acute adrenal ischemia represents a rare cause of adrenal insufficiency which should be promptly diagnosed in order to preserve adrenal vitality and function. Our study aims to retrospectively evaluate the diagnostic accuracy of the CT capsular sign as an indicator of adrenal ischemia and its association with vascular involvement. Between January 2013 and January 2014, 69 consecutive patients (47 men, 22 women; mean age 46; range 22-67) with suspected adrenal insufficiency based on clinical and biochemical data underwent 320-row CT examination in our Emergency Department. Written informed consent was obtained for the CT examinations, and the institutional review board approval was obtained for our retrospective study. CT multi-planar images were retrospectively and independently analyzed by two radiologists searching for the patency of adrenal vessels, enlarged adrenals, the presence of the "capsular sign" represented by a peripheral subtle hyperdense line around a hypodense enlarged adrenal, and the presence of any periadrenal inflammatory changes. All CT findings were then compared with the surgical findings (n = 5), follow-up examinations (n = 20), or autopsy (n = 4). Sensitivity, specificity, diagnostic accuracy (DA), positive predictive value (PPV), and negative predictive value (NPV) were calculated for the "capsular sign" and were further evaluated by ROC analysis. Acute adrenal ischemia occurred in 29/69 patients (42 %), unilateral in 20, and bilateral in 9. Forty of sixty-nine patients (58 %) had no evidence of adrenal disease on CT. Thrombosis of the main adrenal vein was found in 20/29 (69 %) and non-venous ischemia in 9/29 (31 %). The capsular sign was found in 24/29 patients (83 %). Sensitivity, specificity, DA, PPV, and NPV values of 83, 100, 93, 100, and 89 %, respectively, were obtained. The capsular sign represents a CT indicator of acute adrenal ischemia, with a specificity of 100 % and leading to a prompt diagnosis in the early

    Evidence accumulated by our investigations over the years give adequate proof for the existence of circulating antibodies in Chagas disease which bind to beta adrenergic and muscarinic cholinergic receptor of myocardium. The interaction of agonist-like antibodies with neurotransmitter receptors, triggers in the cells intracellular signal transductions that alter the physiological behaviour of the target organs. These events convert the normal cells into pathologically active cells. The interaction of antibodies with heart beta adrenergic and cholinergic receptors triggers physiologic, morphologic, enzymatic and molecular alterations, leading to tissue damage. The analysis of the prevalence and distribution of these antibodies reveals a strong association with cardiac and esophageal autonomic dysfunction in seropositive patients in comparison with those without alteration of the heart and esophagus autonomic disorders: therefore, the presence of these antibodies may partially explain the cardiomyoneurophathy and achalasia of Chagas disease, in which the sympathetic and parasympathetic systems are affected. The deposit of autoantibodies behaving like an agonist on neurotransmitter receptors, induceds desensitization and/or down regulation of the receptors. This in turn, could lead to a progressive blockade of neurotransmitter receptors, with sympathetic and parasympathetic dennervation, a phenomenon that has been described during the course of Chagas cardioneuropathy and achalasia. The clinical relevance of these findings is the demonstration, using biomolecules, of a strong association between the existence of circulating autoantibodies against peptides corresponding to the second extracellular loop of the human heart beta, adrenoceptor and M2 cholinoceptor in chagasic patients, and the presence of dysautonomic symptoms, making these autoantibodies a proper early marker of heart and digestive autonomic dysfunction.

    This special article aims to summarise the current knowledge regarding the two groups of tumours with their origin in the adrenal gland: 1) adrenocortical tumours, derived from the cortex of the adrenal gland and 2) phaeochromocytomas and paragangliomas, neuroendocrine tumours derived from nodes of neural crest derived cells symmetrically distributed at both sides of the entire spine (paragangliomas [PG]). These PGs can be functioning tumors that secrete catecholamines, which confers their typical dark colour after staining with chromium salts (chromaffin tumors). Among these, the term phaeochromocytoma (PC) is restricted to those PGs derived from the chromaffin cells in the adrenal medulla (intra-adrenal PGs), whereas the term PG is used for those sympathetic or parasympathetic ones in an extra-adrenal location. We analyse the state of the art of their pathogenic and genetic bases, as well as their clinical signs and symptoms, the tests currently available for performing their diagnosis (biochemical, hormonal, imaging and molecular studies) and management (surgery, pre- and post-surgical medical treatment), considering the current and developing strategies in chemo- and radiotherapy.

    Adrenal tumors comprise a broad spectrum of benign and malignant neoplasms and include functional adrenal adenomas, pheochromocytomas, primary adrenocortical carcinoma, and adrenal metastases. Percutaneous ablative approaches that have been described and used in the treatment of adrenal tumors include percutaneous radiofrequency ablation, cryoablation, microwave ablation, and chemical ablation. Local tumor ablation in the adrenal gland presents unique challenges, secondary to the adrenal gland's unique anatomic and physiological features. The results of clinical series employing percutaneous ablative techniques in the treatment of adrenal tumors are reviewed in this article. Clinical and technical considerations unique to ablation in the adrenal gland are presented, including approaches commonly used in our practices, and risks and potential complications are discussed.

    Adrenal glands are paired endocrine glands located over the upper renal poles. Adrenal pathologies have various clinical presentations. They can coexist with the hyperfunction of individual cortical zones or the medulla, insufficiency of the adrenal cortex or retained normal hormonal function. The most common adrenal masses are tumors incidentally detected in imaging examinations (ultrasound, tomography, magnetic resonance imaging), referred to as incidentalomas. They include a range of histopathological entities but cortical adenomas without hormonal hyperfunction are the most common. Each abdominal ultrasound scan of a child or adult should include the assessment of the suprarenal areas. If a previously non-reported, incidental solid focal lesion exceeding 1 cm (incidentaloma) is detected in the suprarenal area, computed tomography or magnetic resonance imaging should be conducted to confirm its presence and for differentiation and the tumor functional status should be determined. Ultrasound imaging is also used to monitor adrenal incidentaloma that is not eligible for a surgery. The paper presents recommendations concerning the performance and assessment of ultrasound examinations of the adrenal glands and their pathological lesions. The article includes new ultrasound techniques, such as tissue harmonic imaging, spatial compound imaging, three-dimensional ultrasound, elastography, contrast-enhanced ultrasound and parametric imaging. The guidelines presented above are consistent with the recommendations of the Polish Ultrasound Society.

    Adrenal-sparing surgery is an effective and safe alternative to total adrenalectomy for small, benign adrenal lesions and may decrease the risk of the development of adrenal insufficiency. While series of laparoscopic partial adrenalectomy have demonstrated safety and excellent long-term outcomes, there have been no reports of a complete robot-assisted partial adrenalectomy. We believe that robotic techniques may be useful for this procedure, given the complex vascularity and small size of the adrenal gland. Furthermore, there have been no reports of minimally invasive partial adrenalectomy for management of small, isolated adrenal metastasis. We report a case of robot-assisted partial adrenalectomy in a patient with a history of renal-cell carcinoma who had previously undergone contralateral adrenalectomy for metastasis. We report our surgical technique and short-term follow-up for our patient. To our knowledge, this is the first report of a complete robot-assisted partial adrenalectomy and the first report of minimally invasive partial adrenalectomy for an isolated adrenal metastasis.

  4. Congenital adrenal hyperplasia.

    PubMed

    Merke, Deborah P; Bornstein, Stefan R

    Congenital adrenal hyperplasia (CAH) due to deficiency of 21-hydroxylase is a disorder of the adrenal cortex characterised by cortisol deficiency, with or without aldosterone deficiency, and androgen excess. Patients with the most severe form also have abnormalities of the adrenal medulla and epinephrine deficiency. The severe classic form occurs in one in 15,000 births worldwide, and the mild non-classic form is a common cause of hyperandrogenism. Neonatal screening for CAH and gene-specific prenatal diagnosis are now possible. Standard hormone replacement fails to achieve normal growth and development for many children with CAH, and adults can experience iatrogenic Cushing's syndrome, hyperandrogenism, infertility, or the development of the metabolic syndrome. This Seminar reviews the epidemiology, genetics, pathophysiology, diagnosis, and management of CAH, and provides an overview of clinical challenges and future therapies.

  5. The rat adrenal medulla.

    Tischler, A S

    1989-01-01

    Adult adrenal medullary cells, in many strains of rats, develop diffuse and nodular hyperplasia and neoplasia under a variety of conditions. Both endogenous and exogenous factors affect the development of these proliferative changes. The former include the animals' strain, age, and sex. The latter include drugs and other environmental agents, diet, and perhaps stress. Adrenal medullary neoplasms which arise under diverse circumstances often closely resemble each other both morphologically and functionally, and exhibit characteristics of immature chromaffin cells. Recent data indicate that normal, mature-appearing epinephrine- and norepinephrine-type chromaffin cells are able to divide, and suggest that signals which regulate chromaffin cell function also regulate cell proliferation. Prolongation of these signals or superimposed abnormalities might initiate pathological proliferative states. It remains to be determined whether the mechanisms which promote or prevent cell proliferation in the adult adrenal are related to those involved in normal development.

    Guillain-Barre syndrome (GBS)-associated achalasia is a very rare disease of uncertain cause. We report the case of a patient diagnosed with GBS-associated type I achalasia who was successfully treated with peroral endoscopic myotomy (POEM). A 30-year-old man who was diagnosed with GBS 3 mo before was referred to our department with dysphagia and meal-related regurgitation. The results of esophagography, endoscopy, and high-resolution manometry (HRM) revealed type I achalasia. POEM that utilized a submucosal tunneling technique was performed to treat the GBS-associated type I achalasia. After POEM, smooth passage of a contrast agent into the stomach was shown in follow-up esophagography, and follow-up HRM revealed a decrease in the mean integrated relaxation pressure 22.9 mmHg to 9.6 mmHg. The patient remained without dysphagia for 7 mo, even though the patient’s neurological problems were not fully resolved. POEM may be a safe and effective treatment for GBS-associated type I achalasia. PMID:28223738

    The progression of certain primary esophageal motor disorders to achalasia has been documented; however, the true incidence of this decay is still elusive. This study aims to evaluate: (i) the incidence of the progression of diffuse esophageal spasm to achalasia, and (ii) predictive factors to this progression. Thirty-five patients (mean age 53 years, 80% females) with a manometric picture of diffuse esophageal spasm were followed for at least 1 year. Patients with gastroesophageal reflux disease confirmed by pH monitoring or systemic diseases that may affect esophageal motility were excluded. Esophageal manometry was repeated in all patients. Five (14%) of the patients progressed to achalasia at a mean follow-up of 2.1 (range 1-4) years. Demographic characteristics were not predictive of transition to achalasia, while dysphagia (P= 0.005) as the main symptom and the wave amplitude of simultaneous waves less than 50 mmHg (P= 0.003) were statistically significant. In conclusion, the transition of diffuse esophageal spasm to achalasia is not frequent at a 2-year follow-up. Dysphagia and simultaneous waves with low amplitude are predictive factors for this degeneration.

    Traveling can be dangerous for subjects with kidney insufficiency. Water loss or septic episodes can further increase renal dysfunction. Poor diet can lead to hyperkaliemia. Immunosuppression not only enhances the risk of infection but also complicates administration of live vaccines. Some antimalarial drugs are contraindicated (e.g. mefloquine) and others must be used with precaution. Prior to departure persons requiring hemodialysis should book sessions at centers listed in specialized guidebooks. In addition to infection, risks for hemodialysis patients include thrombosis of the arteriovenous fistula in case of dehydration or hypotension. In subjects with transplanted kidney, the risk of rejection can be enhanced either by poor compliance with immunodepressor treatment or by vaccination-induced antigenic stimulation. Pre-travel evaluation is necessary to determine metabolic, nutritional, and immune status. Subjects with kidney insufficiency and transplanted kidneys should be informed of the dangers and appropriate action in case of trouble.

    Most clinicians are not prepared to provide integrated personal care to address all the clinical needs of women with primary ovarian insufficiency. Design thinking is an engineering methodology used to develop and evaluate novel concepts for systems operation. Here we articulate the need for a seamlessly integrated mobile health system to support genomic research as well as patient care. We also review the pathophysiology and management of primary ovarian insufficiency. Molecular understanding regarding the pathogenesis is essential to developing strategies for prevention, earlier diagnosis, and appropriate management of the disorder. The syndrome is a chronic disorder characterized by oligo/amenorrhea and hypergonadotropic hypogonadism before age 40 years. There may be significant morbidity due to: 1) depression and anxiety related to the loss of reproductive hormones and infertility; 2) associated autoimmune adrenal insufficiency or hypothyroidism; and 3) reduced bone mineral density and increased risk of cardiovascular disease related to estrogen deficiency. Approximately 5% to 10% of women with primary ovarian insufficiency conceive and have a child. Women who develop primary ovarian insufficiency related to a premutation in FMR1 are at risk of having a child with fragile X syndrome, the most common cause of inherited intellectual disability. In most cases of spontaneous primary ovarian insufficiency no environmental exposure or genetic mechanism can be identified. As a rare disease, the diagnosis of primary ovarian insufficiency presents special challenges. Connecting patients and community health providers in real time with investigators who have the requisite knowledge and expertise would help solve this dilemma.

    Peroral endoscopic myotomy (POEM) is a new endoscopic treatment for achalasia. Compared to the classical surgical myotomy, POEM brings at least the advantage of minimal invasiveness. The data provided until now suggest that POEM offers excellent short-term symptom resolution, with improvement of dysphagia in more than 90% of treated patients, with encouraging manometric outcomes and low incidence of postprocedural gastroesophageal reflux. The effectiveness of this novel therapy requires long-term follow-up and comparative studies with other treatment modalities for achalasia. This technique requires experts in interventional endoscopy, with a learning curve requiring more than 20 cases, including training on animal and cadaver models, and with a need for structured proctoring during the first cases. This review aims to summarize the data on the technique, outcomes, safety and learning curve of this new endoscopic treatment of achalasia.

    Achalasia cardia is a disorder of the gastrointestinal tract characterized by dilatation of the oesophagus and collection of food and fluids in the oesophagus leading to massive regurgitation and aspiration of gastric contents. Down’s syndrome has multisystem effects which can also present as difficult airway. Here, we present a case of a 14-year-old girl, a case of Down’s syndrome with Achalasia cardia and mitral valve prolapse posted for Heller’s cardiomyotomy. Anaesthetic concerns were difficult airway due to Downs’s syndrome, massive aspiration risks of Achalasia cardia and haemodynamic instability due to mitral regurgitation. In spite of proper preparation of the patient there was massive regurgitation of oesophageal contents during intubation which was managed successfully. Haemodynamic changes due to mitral valve prolapse also had to be taken care of during the intraoperative period. Postoperative period was uneventful and the child was discharged after one week.

    AIM To investigate the incidence of achalasia in Algeria and to determine its clinical and para-clinical profile. To evaluate the impact of continuing medical education (CME) on the incidence of this disease. METHODS From 1990 to 2014, 1256 patients with achalasia were enrolled in this prospective study. A campaign of CME on diagnosis involving different regions of the country was conducted between 1999 and 2003. Annual incidence and prevalence were calculated by relating the number of diagnosed cases to 105 inhabitants. Each patient completed a standardized questionnaire, and underwent upper endoscopy, barium swallow and esophageal manometry. We systematically looked for Allgrove syndrome and familial achalasia. RESULTS The mean annual incidence raised from 0.04 (95%CI: 0.028-0.052) during the 1990s to 0.27/105 inhabitants/year (95%CI: 0.215-0.321) during the 2000s. The incidence of the disease was two and half times higher in the north and the center compared to the south of the country. One-hundred-and-twenty-nine (10%) were children and 97 (7.7%) had Allgrove syndrome. Familial achalasia was noted in 18 different families. Patients had dysphagia (99%), regurgitation (83%), chest pain (51%), heartburn 24.5% and weight loss (70%). The lower esophageal sphincter was hypertensive in 53% and hypotensive in 0.6%. CONCLUSION The mean incidence of achalasia in Algeria is at least 0.27/105 inhabitants. A good impact on the incidence of CME was noted. A gradient of incidence between different regions of the country was found. This variability is probably related to genetic and environmental factors. The discovery of an infantile achalasia must lead to looking for Allgrove syndrome and similar cases in the family. PMID:27784974

    Peroral endoscopic myotomy (POEM) is a new endoscopic treatment for achalasia with very good short-term results in adults. Data about POEM in pediatric patients are missing. We present the case of a 10-year-old male patient with type I (classic) achalasia, successfully treated with POEM. The procedure was accomplished in a similar fashion to the technique used in adults. Short-term results were fine, with a complete control of dysphagia and absence of reflux. We suggest that POEM is a suitable option in pediatric patients-similar to adults-but long-term results must be awaited.

    Achalasia is characterised by the loss of peristaltic movement in the distal oesophagus and failure of the lower oesophageal sphincter relaxation, which results in impaired oesophageal emptying. We report a case of a 92-year-old frail woman with a history of achalasia, who presented with acute oesophageal obstruction due to impaction of a large amount of food material. She was treated successfully with nifedipine, in combination with Coca-Cola (original product, not sugar free), so avoiding the risks associated with repeated endoscopic intubation and piecemeal removal of the oesophageal content.

    The syndromes of superior mesenteric artery insufficiency are briefly reviewed. Three cases associated with infarction of bowel which were treated with restoration of arterial flow and resection of residual irretrievable bowel are reported. In two patients an embolectomy and in one patient a bypass graft were used to restore arterial continuity. The importance of the recognition and removal of irretrievable bowel at the time of vascular reconstruction is emphasized. Success is not necessarily predicated by the time factor alone, although the importance of early diagnosis and surgical intervention cannot be denied. PMID:14042788

    Chronic venous insufficiency (CVI) is an important and frequent disease for dermatologists, phlebologists and general practitioners. There are various hypotheses for the ethiopathology in CVI, e. g. hormone receptors and impairments concerning the venous contraction or relaxation of the vessel wall and the venous valves might play an important role. At the moment, colour doppler-duplex sonography seems to be the diagnostic method of choice. Modern therapeutic options include compression systems alone or in combination with topical or systemic treatment including minimal invasive methods like endovenous laser or radiofrequency obliteration or foam sclerotherapy.

    1995-07-01

    Adrenal disease can be manifested by endocrine dysfunction or anatomic abnormalities detected by cross-sectional imaging modalities. With the advent of newer and more reliable in vitro assays and a better understanding of the spectrum of adrenal pathology, the physician can now adopt a more accurate and cost-effective approach to the diagnosis of adrenal disease. Both functional and anatomic imaging modalities can play an important role in the evaluation of the incidental adrenal mass, the early detection of adrenal metastases, differentiation of the various causes of Cushings's syndrome, selection of patients for potentially curative surgery in primary aldosteronism and adrenal hyperandrogenism, and localization of pheochromocytomas and neuroblastomas. The usefulness of the adrenal cortical radiopharmaceutical, 131I-6-beta-iodomethylnorcholesterol (NP-59), and the adrenal medullary radiopharmaceuticals, 131I and 123I-metaiodobenzylguanidine (MIBG), is detailed for these various clinical settings and the role of NP-59 and MIBG is contrasted to that of the cross-sectional modalities, computed tomography and magnetic resonance imaging (MRI). Incidental adrenal masses are common, but malignancies are few. Imaging studies select those patients who require a further evaluation by biopsy examination or adrenalectomy. In the hyperfunctioning endocrine states, such as Cushing's syndrome, primary aldosteronism, adrenal androgenism, and pheochromocytoma, correlation of biochemical findings with both functional and anatomic imaging is necessary to avoid inappropriate and ineffective surgical intervention, yet not miss an opportunity for curative resection. Lastly, MIBG and MRI are complementary in the detection and staging of neuroblastoma.

    We report a combination of precocious pseudopuberty and adrenal insufficiency in a 4 year-old boy who had received an off-label 'appetite stimulant' syrup and excessive virilization in a 2 year-old girl who had received the same medication. Both patients presented with excessive virilization for a period of approximately 1-2 years. The syrup contains cyproheptadine and methandienone, a derivative of testosterone. Both cyproheptadine and methandienone were responsible for severe adrenal suppression in the boy. Methandienone undoubtedly caused precocious virilization in both children. Cessation of the syrup led to partial regression of virilization in both children and normalization of adrenal reserve function in the boy.

    The aim of this study was to observe the usefulness of betahistine dihydrochloride--Betaserc--in therapy for vestibular disorders in patients with vertebrobasilar insufficiency. Two groups of patients, in each of which were 150 patients (mean age, 52.2 years), were tested on the basis of videonystagmography and stabilometry. Betaserc was administrated in two separate doses: 8 mg three times daily and 16 mg three times daily for 120-180 days (mean, 132 days). In every case before and after therapy, visuo-oculomotor and vestibulo-oculomotor reflexes were tested, and amplitude and velocity of the sway were measured during dynamic posturographic testing. After Betaserc treatment, pathological visuo-oculomotor reactions and pathological cervical test results disappeared in most cases: Smooth pursuit improved in 59.9% of cases and saccadic movements in 55.9% of patients, and cervical nystagmus disappeared in 62.2% of tested people. During stabilometry, mean and maximal platform amplitude and mean head velocity decreased as compared with results from tests performed before treatment. These observations were significant after the greater dose of Betaserc; nonetheless, improvement was noted after both doses. The usefulness of Betaserc in vertebrobasilar insufficiency was proved, 4-6 months' therapy was sufficient, and the effect on central compensation seemed to be most probable.

    The study was aimed at bettering therapeutic outcomes for patients suffering from adrenal-aetiology arterial hypertension, with the objective deemed attainable at the expense of revealing and removing the underlying causes potentially contributing to unfavourable results obtained after roentgenoendovascular ablation of the adrenal glands. We retrospectively examined the medical records of 49 patients having undergone hospital treatment within the time frame from 1992 to 2007 for recurrent arterial hypertension poorly controlled by previously endured roentgenoendovascular (REV) interventions. The identified causes contributing heavily to poor clinical outcomes obtained after the REV-ablation procedures appeared to have been as follows: renal parenchymatous diseases in 20 patients having a long history of arterial hypertension with evidence ofnephroangiosclerosis; insufficient devitalisation of the adrenal glands in a further 19 patients; a pheochromocytoma of the right adrenal gland in only one instance; and newly onset renovascular hypertension in the remaining nine subjects. It was determined that poor therapeutic outcomes had primarily been caused by overestimating the indications for performing REV ablation of the adrenal glands, being seemingly wanton as a corrective measure to have been taken in the presence of inflammatory diseases of the renal parenchyma and secondary hyperplasia of the adrenal gland, with the second-in-order contributory cause appearing to be insufficient devitalisation of the adrenal glands afflicted by hyperplasia and/or aldosteroma. The development of renal artery stenosis in the remote period after REV interventions may also be responsible for a relapse of arterial hypertension, which is quite often the case.

    Background and aim The cysts may potentially affect any organ; adrenals cysts are rare. This is a review of the literature regarding adrenal cysts, focusing on children and young adults. General data Three major types have been described: pure cysts (endothelial, epithelial, and hemorrhagic or pseudocyst), parasitic (as hydatid) cysts and cystic part of a tumour (most frequent are neuroblastoma, ganglioneuroma, pheocromocytoma, and teratoma). The complications are: bleeding, local pressure effects; infection; rupture (including post-traumatic); arterial hypertension due to renal vessels compression. Adrenal hemorrhage represents a particular condition associating precipitating factors such as: coagulation defects as Factor IX or X deficiency, von Willebrand disease, thrombocytopenia; antiphospholipid syndrome; previous therapy with clopidogrel or corticosteroids; the rupture of a prior tumour. At birth, the most suggestive features are abdominal palpable mass, anemia, and persistent jaundice. Adrenal insufficiency may be found especially in premature delivery. The hemorrhage is mostly self-limiting. Antenatal ultrasound diagnosis of a cyst does not always predict the exact pathology result. The most important differential diagnosis of adrenal hemorrhage/hemorrhagic cyst is cystic neuroblastoma which is highly suggestive in the presence of distant metastases and abnormal catecholamine profile. The major clue to differentiate the two conditions is the fact that the tumor is stable or increases over time while the adrenal hemorrhage is expected to remit within one to two weeks. Conclusion Pediatric adrenal cysts vary from simple cysts with a benign behavior to neoplasia- related lesions displaying severe prognosis as seen in cystic neuroblastoma. A multidisciplinary team is required for their management which is conservative as close follow-up or it makes necessary different surgical procedures in cases with large masses or if a malignancy suspicion is presented

    Abstract The laparoscopic adrenalectomy is considered as the procedure of choice for the treatment of adrenal hyperplasia and tumor lesions. However, some special situations may limit the use of this method due to the difficulty to locate the gland and perform the lesion excision. We analyze 2 patients of a left adrenal tumor, explaining how they have overcome the difficulties in both situations. The first case was a patient with a history of intra-abdominal surgery and the other patient suffered from severe obesity. We performed with the use of the gamma probe, and the 2 cases, was of great help to access and glandular localization. The help of gamma probe test was achieved in the surgical bed, that removal was complete. The use of the portable gamma probe facilitated the access to the left adrenal gland as well as conducting the glandular excision without delay, despite the difficulties due to the intra abdominal surgery caused by the previous surgery, and in the case of severe obesity.

  8. Congenital lipoid adrenal hyperplasia

    PubMed Central

    2014-01-01

    Congenital lipoid adrenal hyperplasia (lipoid CAH) is the most fatal form of CAH, as it disrupts adrenal and gonadal steroidogenesis. Most cases of lipoid CAH are caused by recessive mutations in the gene encoding steroidogenic acute regulatory protein (StAR). Affected patients typically present with signs of severe adrenal failure in early infancy and 46,XY genetic males are phenotypic females due to disrupted testicular androgen secretion. The StAR p.Q258X mutation accounts for about 70% of affected alleles in most patients of Japanese and Korean ancestry. However, it is more prevalent (92.3%) in the Korean population. Recently, some patients have been showed that they had late and mild clinical findings. These cases and studies constitute a new entity of 'nonclassic lipoid CAH'. The cholesterol side-chain cleavage enzyme, P450scc (CYP11A1), plays an essential role converting cholesterol to pregnenolone. Although progesterone production from the fetally derived placenta is necessary to maintain a pregnancy to term, some patients with P450scc mutations have recently been reported. P450scc mutations can also cause lipoid CAH and establish a recently recognized human endocrine disorder. PMID:25654062

    Disseminated cryptococcosis most commonly occurs in immunosuppressed patients and can rarely affect the adrenal glands. We report on a patient with biopsy proven bilateral adrenal cryptococcosis resulting in primary adrenal insufficiency, which was evaluated with whole-body positron emission tomography/computed tomography scan using (18)F-FDG. Both enlarged adrenal glands presented intensely increased (18)F-FDG activity in the periphery, while central necrotic regions were photopenic. Although diagnosis was established by adrenal gland biopsy, (18)F-FDG positron emission tomography/computed tomography scan can significantly contribute to the assessment of disease activity and monitoring of treatment response. Furthermore, fungal infections should always be considered when encountering hypermetabolic adrenal masses, especially in the setting of immunodeficient patients.

Creatine kinase and triglyceride levels were measured to elucidate the etiology of adrenal hypoplasia and were above normal limits in both cases. Both patients required steroid and salt supplementation. They were both found to have Xp21.2 deletions (DMD, NR0B1, GK, IL1RAPL1). We conclude that AI in the context of other genetic abnormalities should prompt chromosomal investigations in the absence of another unifying explanation. PMID:27087023

    Extra-oesophageal autonomic dysfunction in idiopathic achalasia is not well documented, due to contradictory results reported. We aimed to study the cardiovascular and pancreatic autonomic function in patients with idiopathic achalasia. Thirty patients with idiopathic achalasia (16M/14F; 34.5 +/- 10.8 years) and 30 healthy volunteers (13M/17F; 34.8 +/- 10.7 years) were prospectively studied. Age >60 years and conditions affecting results of autonomic evaluation were excluded. Both groups underwent the sham feeding test and plasmatic levels of pancreatic polypeptide (PP) were determined by radioimmunoassay (basal, at 5, 10, 20 and 30 min). Cardiovascular parasympathetic (deep breathing, standing, Valsalva) and sympathetic function (postural decrease of systolic blood pressure, Handgrip test) were assessed. Statistical comparison of basal and increase levels of PP and parasympathetic/sympathetic cardiovascular parameters was performed between groups. Basal levels of PP were similar in controls and patients and maximum increase of PP during sham feeding test. A similar rate of abnormal cardiovascular tests was found between groups (P > 0.05). E/I ratio was the mostly impaired parameter (patients: 36.7% vs controls: 20%, P = 0.15, chi-squared test). Autonomic cardiovascular tests and pancreatic response to vagal stimulus are not impaired in patients with primary achalasia of the oesophagus.

    Idiopathic achalasia is characterized by the absence of peristalsis secondary to loss of neurons in the myenteric plexus that hampers proper relaxation of the lower esophageal sphincter. Achalasia can be considered a multifactorial disorder as it occurs in related individuals and is associated with HLA class II genes, thereby suggesting genetic influence. We used microarray technology and advanced in-silico functional analyses to perform the first genome-wide expression profiling of mRNA in tissue samples from 12 achalasia and 5 control patients. It revealed 1,728 differentially expressed genes, of these, 837 (48.4%) were up-regulated in cases. In particular, genes participating to the smooth muscle contraction biological function were mostly up-regulated. Functional analysis revealed a significant enrichment of neuronal/muscular and neuronal/immunity processes. Upstream regulatory analysis of 180 genes involved in these processes suggested TLR4 and IL18 as critical key-players. Two functional gene networks were significantly over-represented: one involved in organ morphology, skeletal muscle system development and function, and neurological diseases, and the other participating in cell morphology, humoral immune response and cellular movement. These results highlight on pivotal genes that may play critical roles in neuronal/muscular and neuronal/immunity processes, and that may contribute to the onset and development of achalasia.

    The human adult adrenal cortex is composed of the zona glomerulosa (zG), zona fasciculata (zF), and zona reticularis (zR), which are responsible for production of mineralocorticoids, glucocorticoids, and adrenal androgens, respectively. The final completion of cortical zonation in humans does not occur until puberty with the establishment of the zR and its production of adrenal androgens; a process called adrenarche. The maintenance of the adrenal cortex involves the centripetal displacement and differentiation of peripheral Sonic hedgehog-positive progenitors cells into zG cells that later transition to zF cells and subsequently zR cells.

    Multiple traumatic and non-traumatic adrenal emergencies are occasionally encountered during the cross-sectional imaging of emergency department patients. Traumatic adrenal hematomas are markers of severe polytrauma, and can be easily overlooked due to multiple concomitant injuries. Patients with non-traumatic adrenal emergencies usually present to an emergency department with a non-specific clinical picture. The detection and management of adrenal emergencies is based on cross-sectional imaging. Adrenal hemorrhage, adrenal infection, or rupture of adrenal neoplasm require immediate detection to avoid dire consequences. More often however, adrenal emergencies are detected incidentally in patients being investigated for non-specific acute abdominal pain. A high index of suspicion is required for the establishment of timely diagnosis and to avert potentially life-threatening complications. We describe cross-sectional imaging findings in patients with traumatic and non-traumatic adrenal hemorrhage, adrenal infarctions, adrenal infections, and complications of adrenal masses.

    AIM: To investigate the relationship between upper esophageal sphincter abnormalities achalasia treatment METHODS: We performed a retrospective study of 41 consecutive patients referred for high resolution esophageal manometry with a final manometric diagnosis of achalasia. Patients were sub-divided by presence or absence of Upper esophageal sphincter (UES) abnormality, and clinical and manometric profiles were compared. Correlation between UES abnormality and sub-type (i.e., hypertensive, hypotensive or impaired relaxation) and a number of variables, including qualitative treatment response, achalasia sub-type, co-morbid medical illness, psychiatric illness, surgical history, dominant presenting symptom, treatment type, age and gender were also evaluated. RESULTS: Among all 41 patients, 24 (58.54%) had a UES abnormality present. There were no significant differences between the groups in terms of age, gender or any other clinical or demographic profiles. Among those with UES abnormalities, the majority were either hypertensive (41.67%) or had impaired relaxation (37.5%) as compared to hypotensive (20.83%), although this did not reach statistical significance (P = 0.42). There was no specific association between treatment response and treatment type received; however, there was a significant association between UES abnormalities and treatment response. In patients with achalasia and concomitant UES abnormalities, 87.5% had poor treatment response, while only 12.5% had favorable response. In contrast, in patients with achalasia and no UES abnormalities, the majority (78.57%) had good treatment response, as compared to 21.43% with poor treatment response (P = 0.0001). After controlling for achalasia sub-type, those with UES abnormality had 26 times greater odds of poor treatment response than those with no UES abnormality (P = 0.009). Similarly, after controlling for treatment type, those with UES abnormality had 13.9 times greater odds of poor treatment response

    We report the postmortem findings of two siblings with gross and microscopic features consistent with IMAGe association (Intrauterine growth retardation, Metaphyseal dysplasia, Adrenal hypoplasia congenita, and Genital anomalies) with an emphasis on the histopathology of the adrenal gland in this rare syndrome. The first sibling was an 8-week old male diagnosed postnatally with primary adrenal insufficiency. There was no deletion of the DAX1 gene by FISH. Examination at autopsy revealed dysmorphic features including frontal bossing, epicanthal folds, flat philtrum, cryptorchidism, penile chordee, overriding fourth toe, and height and weight below 3rd percentile. Grossly, the adrenal glands were not identified; however, microscopic examination of the suprarenal soft tissue revealed a 3 mm focus of disorganized fetal adrenal cortex with distended "cytomegalic" cells with abundant pink eosinophilic cytoplasm, vesicular nuclei, and cytoplasmic vacuolization. A minute focus of permanent adult cortex was also seen, but no adrenal medulla was identified. An autopsy of the sibling, who died 12 years previously at day 9 of life, revealed dysmorphic facial features with cryptorchidism and a large phallus. The adrenal glands were grossly hypoplastic (11 mm). Histologically, the adrenal glands showed disorganized fetal cortex with cytomegalic cells, a larger amount of permanent adult cortex, and bizarre nuclei with numerous pseudoinclusions. While there is currently limited information regarding the histopathologic adrenal findings in IMAGe association, our small case series suggests overlapping features between X-linked recessive congenital adrenal hypoplasia (cytomegalic cells with lack of permanent adult cortex) and autosomal recessive congenital adrenal hypoplasia (diminished permanent adult cortex without cytomegalic cells).

    Primary idiopathic achalasia is the most common form of the rare esophageal motility disorders. A curative therapy which restores the normal motility does not exist; however, the therapeutic principle of cardiomyotomy according to Ernst Heller leads to excellent symptom control in the majority of cases. The established standard approach is Heller myotomy through the laparoscopic route (LHM), combined with Dor anterior fundoplication for reflux prophylaxis/therapy. At least four meta-analyses of randomized controlled trials (RCTs) have demonstrated superiority of LHM over pneumatic dilation (PD); therefore, LHM should be used as first line therapy (without prior PD) in all operable patients. Peroral endoscopic myotomy (POEM) is a new alternative approach, which enables Heller myotomy to be performed though the endoscopic submucosal route. The POEM procedure has a low complication rate and also leads to good control of dysphagia but reflux rates can possibly be slightly higher (20-30%). Long-term results of POEM are still scarce and the results of the prospective randomized multicenter trial POEM vs. LHM are not yet available; however, POEM seems to be the preferred treatment option for certain indications. Within the framework of the tailored approach for achalasia management of POEM vs. LHM established in Würzburg, we recommend long-segment POEM for patients with type III achalasia (spasmodic) and other hypercontractile motility disorders and potentially type II achalasia (panesophageal compression) with chest pain as the lead symptom, whereas LHM can also be selected for type I. For sigmoid achalasia, especially with siphon-like transformation of the esophagogastric junction, simultaneous hiatal hernia and epiphrenic diverticula, LHM is still the preferred approach. The choice of the procedure for revisional surgery in case of recurrent dysphagia depends on the suspected mechanism (morphological vs. functional/neuromotor).

    Peroral endoscopic myotomy (POEM) is a novel approach to performing esophageal myotomy for the treatment of achalasia. This review aims to assess subjective and objective metrics of achalasia treatment efficacy, perioperative adverse events and the incidence of postoperative gastroesophageal reflux disease in patients treated with POEM. Secondary aims include a pooled analysis comparison of the clinical outcomes and procedural safety of POEM versus laparoscopic Heller's myotomy (LHM). A systematic review of the literature, up to and including January 15, 2015, was conducted for studies reporting POEM outcomes. Studies comparing POEM to LHM were also included for the purpose of pooled analysis. Outcomes from 1122 POEM patients, from 22 studies, are reported in this systematic review. Minor operative adverse events included capno/pneumo-peritoneum (30.6%), capno/pneumo-thorax (11.0%) and subcutaneous emphysema (31.6%). Major operative adverse events included mediastinal leak (0.3%), postoperative bleeding (1.1%) and a single mortality (0.09%). There was an improvement in lower esophageal sphincter pressure and timed barium esophagram column height of 66% and 80% post-POEM, respectively. Symptom improvement was demonstrated with a pre- and post-POEM Eckardt score ± standard deviation of 6.8 ± 1.0 and 1.2 ± 0.6, respectively. Pre- and post-POEM endoscopy showed esophagitis in 0% and 19% of patients, respectively. The median (interquartile range) points scored for study quality was 15 (14-16) out of total of 32. Pooled analysis of three comparative studies between LHM and POEM showed similar results for adverse events, perforation rate, operative time and a nonsignificant trend toward a reduced length of hospital stay in the POEM group. In conclusion, POEM is a safe and effective treatment for achalasia, showing significant improvements in objective metrics and achalasia-related symptoms. Randomized comparative studies of LHM and POEM are required to determine the

    Adrenal carcinoma is a rare malignancy of poor prognosis. The most common clinical presentation is secondary to hormone production, while the development of symptomatic hypoglycemia is exceptional. We report the case of a 37 year old-woman admitted to hospital with severe hypoglycemia, hypertension, hypokalemia and amenorrhea. In the laboratory we found hypoglycemia, with low insulin levels, and androgen levels in tumor range. CT of abdomen and pelvis showed a heterogeneous lesion of solid appearance without a cleavage plane relative to liver parenchyma, and intense contrast enhancement. Retroperitoneal mass was removed, and the patient evolved without complications, blood glucose and potassium were normalized, blood pressure stabilized and menstrual cycles recovered.

    Background We assessed whether a high-resolution impedance manometry (HRIM) metric, bolus flow time (BFT) across the esophagogastric junction (EGJ), was abnormal in achalasia patients subtyped by the Chicago Classification and compared BFT to other HRM metrics. Methods HRIM studies were performed in 60 achalasia patients (14 type I, 36 type II and 10 type III) and 15 healthy controls. Studies were analyzed with a MATLAB program to calculate BFT using a virtual HRIM sleeve. Integrated relaxation pressure (IRP) and basal end-expiratory EGJ pressure were also calculated. The relationship between BFT and dysphagia symptom scores was assessed using the impaction dysphagia questionnaire (IDQ). Key Results Median BFT was significantly lower in achalasia patients (0.5 s, range 0.0 to 3.5 s) compared to controls (3.5 s, range 2.0 to 5.0 s) (P<0.05). BFT was significantly lower in types I and II than in type III achalasia in both the supine and upright positions (p<0.0001). BFT was the only HRIM metric significantly associated with IDQ score in both the supine (R2 =0.20, p=0.0046) and upright positions (R2 =0.27, p=0.0002). Conclusions & Inferences BFT was significantly reduced in all subtypes of achalasia and complementary to the IRP as a diagnostic discriminant in equivocal achalasia cases. Additionally, BFT had a more robust correlation with dysphagia severity compared to other metrics of EGJ function. PMID:26088614

However, it is unclear whether esophageal carcinoma is frequent when achalasia has been treated successfully and the patient is without dysphagia. In this study, we reviewed patients with esophageal carcinoma who were detected by regular follow-up after surgical treatment of achalasia. Case Report: Esophageal cancer was detected by periodic upper GI endoscopy in 6 patients. Most of them had early cancers that were treated by endoscopic resection. All 6 patients had undergone surgery for achalasia and the outcome had been rated as excellent or good. Annual follow-up endoscopy was done and the average duration of follow-up until cancer was seen after surgery was 14.3 years (range: 5 to 40 years). Five patients had early cancer. Four cases had multiple lesions. Conclusions: In conclusion, surgery for achalasia usually improves passage symptoms, but esophageal cancer still arises in some cases and the number of tumors occurring many years later is not negligible. Accordingly, long-term endoscopic follow-up is needed for detection of malignancy at an early stage. PMID:27840406

    The esophageal scintigraphy is a technique used to evaluate the motility and the clearance of the esophagus. The patients with achalasia of the cardia were evaluated, before treating them with pneumatic dilatation and after. The reason is to evaluate the efficiency of the pneumatic dilatation technique in the treatment of esophageal achalasia. The pneumatic dilatation with an instrument type Rigiflex is a well/handled and used technique in our clinic. In the study 22 patients were included and we had in view the esophageal transit time and the residuary radioactivity before and after the pneumatic dilatation. We established an important statistical improvement of the data obtained after the dilatation comparative with the data before the treatment (p < 0.01).

    Esophageal achalasia is the best described primary esophageal motility disorder. Endoscopic ultrasound (EUS) is considered a useful adjunct for grading and establishing the prognosis of these patients. Recent experience using Da Vinci robotic assisted myotomy has demonstrated that this is a safe and effective approach of treatment. The benefit of magnification and three dimensional imaging helps prevent esophageal perforation and identify residual circular muscle fibers. This paper reports the relative efficacy and safety of intraoperative ultrasound during robotic assisted myotomy in a patient with severe achalasia. Intraoperative esophageal endoscopic ultrasound is a safe technique that may improve the success rate of surgery by confirming the adequacy of myotomy, thereby decreasing the likelihood of recurrent symptoms.

    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.

    Adrenal lymphoma is extremely rare. The prognostic depends on involvement of other organs (such as the central nervous system) responsible for lower median survival. We report the case of a 51-year-old man with non Hodgkin's Diffuse Large B Cell Lymphoma (DLBCL) involving the central nervous system (CNS) and the adrenal glands simultaneously. The endocrine exploration revealed a partial adrenal insufficiency and ruled out a pheochromocytoma. Computerized tomographic (CT) scan directed needle biopsy of the adrenal gland allowed the diagnostic of non-Hodgkin lymphoma (NHL). CNS biopsies showed similar histopathologic lesions. After aggressive polychemotherapy and methotrexate intrathecal injection, a dissociated therapeutic response was observed with a decrease of the cerebral lesion and an increase of the adrenal mass. This result may be explained by the efficacy of corticosteroid therapy on cerebral edema. The prognosis was poor with tumor infiltration of the leptomeninges and death 16 months after diagnosis.

    Among the therapeutic options for achalasia are pneumatic dilatation (PD), an appropriate long-term therapy, and botulinum toxin injection (BT) that is a relatively short-term therapy. This study aimed to compare therapeutic effect of repetitive pneumatic dilation with a combined method (botulinum toxin injection and pneumatic dilation) in a group of achalasia patients who are low responder to two initial pneumatic dilations. Thirty-four patients with documented primary achalasia that had low response to two times PD (<50% decrease in symptom score and barium height at 5 minute in timed esophagogram after 3 month of late PD) were randomized to receive pneumatic dilation (n=18) or botulinum toxin injection and pneumatic dilation by four weeks interval (n=16), PD and BT+PD groups respectively. Symptom scores were evaluated before and at 1, 6 and 12 months after treatment. Clinical remission was defined as a decrease in symptom score > or = 50% of baseline. There were no significant differences between the two groups in gender, age and achalasia type. Remission rate of patients in BT-PD group in comparison with PD group were 87.5% vs. 67.1% (P = 0.7), 87.5% vs. 61.1% (P = 0.59) and 87.5% vs. 55.5% (P = 0.53) at 1, 6 and 12 months respectively .There were no major complications in either group. The mean symptom score decreased by 62.71% in the BT-PD group (P < 0.002) and 50.77% in the PD group (P < 0.01) at the end of the first year. Despite a better response rate in BT+PD group, a difference was not statistically significant. A difference may be meaningful if a large numbers of patients are included in the study.

Fifty-nine patients with achalasia were treated with retrievable, fully covered metal stents. Symptoms using a global symptom score (0-10), lower esophageal sphincter (LES) resting pressure, LES relaxation, and simultaneous contraction of the esophagus were analyzed before and 1 week and 1 month after intervention. Complications and treatment outcomes were followed up at 6, 12, 18, and 24 months postoperatively. Stent placement was successful, and clinical symptoms resolved (P < 0.01) in all patients. Regurgitation, dysphagia and chest pain improved significantly (all P < 0.01). Therapy improved LES resting pressure (51.4 ± 9.7 mmHg pretherapy vs. 20.9 ± 8.1 mmHg post-therapy), LES relaxation (58.1 ± 17.1% pretherapy vs. 84.5 ± 18.9% post-therapy), and simultaneous contraction of the esophagus (36.1 ± 8.6% pretherapy vs. 69.4 ± 23.1% post-therapy) 1 month after stent placement (all P < 0.01). The cumulative clinical remission rates 6, 12, 18, 24, 30, and 36 months after stent removal were 90.9%, 81.8%, 76.4%, 69.1%, 65.5%, and 49.1%, respectively. All patients tolerated stent placement. Twelve patients (25.5%) complained of substernal pain and five (10.6%) had substernal burning. Stents migrated in four patients (8.5%). Insertion of retrievable, fully covered metal stents is an effective and safe treatment in patients with achalasia.

    Adrenal incidentalomas are a heterogeneous group of pathological entities, including benign or malignant adrenocortical or medullary tumors, hormonally active or inactive lesions, which are identified incidentally during the examination of nonadrenal-related abdominal complaints. About 1.5% to 23% of adrenal incidentalomas are pheochromocytomas. Composite pheochromocytoma is a rare tumour of adrenal medulla with divergente clinical course. This type of pheochromocytoma is designated "composite" or "mixed," depending on whether pheochromocytoma and nonpheochromocytoma components show the same embryologic origin. Nonpheochromocytoma components found in the composite pheochromocytoma include ganglioneuroma, ganglioneuroblastoma, neuroblastoma, and malignant schwannoma. The biologic behavior of composite pheochromocytomas may be as difficult to predict as more traditional pheochromocytomas; based on the number of cases reported to date the presence of areas resembling ganglioneuroblastoma or neuroblastoma does not necessary indicate a poor prognosis. Some may behave in a malignant fashion with metastasis by a component of the tumour which has neural features. Pheochromocytomas and paragangliomas are well-defined entities. Some of their nonsporadic associations and unusual morphological appearances are not universally appreciated. We report on a rare association of left adrenal CP, with typical right adrenal phochromocytoma and retroperitoneal paraganglioma, and a review of literature. We analyzed the clinical and immunohistochemical features in a 24-year-old woman with composite pheochromocytoma localized in the left adrenal gland and associated with blood pressure of 200/140 mmHg. Abdominal computed tomography and 131-J MIBG revealed a 65 x 60 mm mass in the right adrenal gland, but no revealed 45 x 40 mm retroperitoneal mass and 20 x 20 mm mass in the left adrenal region. Serum and urinary adrenaline levels were high, and catecholamine levels in the blood sample of

    The management of achalasia remains controversial, with little consensus on the optimal patient treatment pathway. In our own esophageal unit, we offer pneumatic dilatation as the initial therapy in most patients as first-line therapy. In this study, we aimed to examine the safety and efficacy of our own approach to the management of patients with a diagnosis of achalasia, examining symptomatic outcomes, patient satisfaction, and need for further intervention, as well as examining patient factors associated with treatment failure. Sixty-seven consecutive patients underwent pneumatic dilatation as first-line therapy (53% male, mean age 46 years). All attended regular outpatient follow-up (mean 37, range 3-132 months). Twenty-five percent of patients required a second intervention because of symptom recurrence, at a median period of 4.5 months. Symptomatic outcomes were excellent or good in 80%. Significant predictors of treatment failure and poor symptom score included a younger age at the time of diagnosis and increased esophageal diameter on barium swallow. This study suggests that pneumatic dilatation is a safe and effective approach as first-line therapy in patients with newly diagnosed achalasia.

    Peroral endoscopic myotomy (POEM) is a newly developed, less invasive treatment for esophageal achalasia that requires general anesthesia under positive pressure ventilation. In this retrospective case series, we describe the anesthetic management of 28 consecutive patients who underwent POEM for esophageal achalasia. Anesthesia was maintained with sevoflurane and remifentanil under positive pressure ventilation through a tracheal tube. Retained contents in the esophagus were evacuated just before anesthesia induction to prevent regurgitation into the trachea. The POEM procedure was performed using an orally inserted flexible fiberscope. Elevation of end-tidal carbon dioxide after initiating esophageal carbon dioxide insufflation was observed in all patients and was treated by minute adjustments to the ventilation volume. Scopolamine butylbromide-induced tachycardia in one patient was treated with landiolol hydrochloride, which is a short-acting beta 1-selective blocker. Minor subcutaneous emphysema around the neck was observed in one patient. POEM was successfully completed, and tracheas were extubated immediately after the procedure in all patients. Our findings suggest that prevention of aspiration pneumonia during anesthesia induction, preparation for carbon dioxide insufflation-related complications, and treatment of scopolamine butylbromide-induced tachycardia play important roles in safe anesthesia management of POEM for esophageal achalasia.

    Objective To comprehensively characterize androgens and androgen precursors in classic 21-hydroxylase deficiency (21OHD) and to gain insight to the mechanisms of their formation. Design Serum samples were obtained from 38 patients (19 men) with classic 21OHD, age 3-59, and 38 sex- and age-matched controls; 3 patients with 11β-hydroxylase deficiency; 4 patients with adrenal insufficiency; and 16 patients (8 men) undergoing adrenal vein sampling. Paraffin-embedded normal (n=5) and 21OHD adrenal tissue (n=3) was used for immunohistochemical studies. Methods We measured 11 steroids in all sera using liquid chromatography-tandem mass spectrometry. Immunofluroescence localized 3β-hydroxysteroid dehydrogenase type 2 (HSD3B2) and cytochrome b5 (CYB5A) within the normal and 21OHD adrenals. Results Four 11-oxygenated 19-carbon (11oxC19) steroids were significantly higher in male and female 21OHD patients than in controls: 11β-hydroxyandrostenedione, 11-ketoandrostenedione 11β-hydroxytestosterone, and 11-ketotestosterone (3-4-fold, p< 0.0001). For 21OHD patients, testosterone and 11-ketotestosterone were positively correlated in females, but inversely correlated in males. All 11oxC19 steroids were higher in adrenal vein than in inferior vena cava samples from men and women and rose with cosyntropin stimulation. Only trace amounts of 11oxC19 steroids were found in sera from patients with 11β-hydroxylase deficiency and adrenal insufficiency, confirming their adrenal origin. HSD3B2 and CYB5A immunoreactivities were sharply segregated in the normal adrenal glands, whereas areas of overlapping expression were identified in the 21OHD adrenals. Conclusions All four 11oxC19 steroids are elevated in both men and women with classic 21OHD. Our data suggest that 11oxC19 steroids are specific biomarkers of adrenal-derived androgen excess.

    Exocrine pancreatic insufficiency usually does not develop before reduction of enzyme output by more than 90%. Patients with pancreatic insufficiency have a ravenous appetite but fail to thrive from malnutrition. The caloric deprivation is primarily due to fat malabsorption, recognized by the passage of bulky foul smelling greasy stools. Several isolated enzyme deficiencies can be separated from diseases with generalised pancreatic insufficiency. Under replacement therapy with pancreatic enzyme supplements most patients improve and gain weight, although fat and bile acid malabsorption are not abolished.

    The motility of the pharynx and upper esophageal sphincter (UES) is still poorly understood. It is also unclear if the motility of this area may be compromised in patients with achalasia. This study aims to evaluate the motility of the pharynx, UES, and proximal esophagus in patients with esophageal achalasia. Sixty patients with achalasia underwent high-resolution manometry (HRM) (52 % females, mean age 54 years). Esophageal dilatation was classified according to the radiologic diameter in Type I (<4 cm): 6 %; Type II (4-7 cm): 36 %; Type III (7-10 cm): 34 %; and Type IV (>10 cm): 24 %. HRM classified 43 % of the patients as Chicago Type I and 57 % as Type II. Manometric parameters were compared to normal values obtained from a previous study in volunteers. The motility of the velopharynx showed short, premature, and hypertonic contraction. The epiglottis also showed hypertonic contraction. The UES had increased residual pressure. Chicago classification Type II patients had higher UES residual pressure (p = 0.03). The degree of esophageal dilatation did not correlate with manometric parameters. Achalasia may affect the motility of the pharyngo-upper esophageal area. The changes observed may represent functional alterations to prevent aspiration, especially in patients with Chicago classification Type II achalasia.

    Summary Checkpoint inhibitors, such as ipilimumab and pembrolizumab, have transformed the prognosis for patients with advanced malignant melanoma and squamous non-small-cell lung cancer, and their use will only expand as experience is gained in a variety of other malignancies, for instance, renal and lymphoma. As the use of checkpoint inhibitors increases, so too will the incidence of their unique side effects, termed immune-related adverse events (irAEs), which can affect dermatological, gastrointestinal, hepatic, endocrine and other systems. Nivolumab is a monoclonal antibody that blocks the human programmed death receptor-1 ligand (PD-L1) found on many cancer cells and is licensed for the treatment of advanced malignant melanoma. We describe the first case of nivolumab-induced adrenalitis resulting in primary adrenal failure presenting with hyponatraemia in a 43-year-old man with malignant melanoma. The case highlights the potentially life-threatening complications of checkpoint inhibitors and the need for patient education and awareness of irAEs among the wider clinical community because such side effects require prompt recognition and treatment. Learning points: Nivolumab can cause primary adrenal insufficiency. Not all cases of hyponatraemia in patients with malignancy are due to SIADH. Any patient on a checkpoint inhibitor becoming unwell should have serum cortisol urgently measured and if in doubt hydrocortisone therapy should be initiated. Although hyponatraemia can occur in patients with ACTH deficiency, the possibility of primary adrenal failure should also be considered and investigated by measurement of renin, aldosterone and ACTH. Patients receiving checkpoint inhibitors require education on the potential risks of hypocortisolaemia. PET imaging demonstrated bilateral increased activity consistent with an autoimmune adrenalitis. PMID:27857838

    BACKGROUND AND AIMS—Conventional short term manometry is a valuable tool in the diagnosis of achalasia but the technique may fail to detect intermittent motor events. The aim of this study was to investigate the pattern of lower oesophageal sphincter (LOS) and oesophageal pressures during prolonged recording in patients with achalasia.
METHODS—Eleven patients with idiopathic achalasia were studied. Prolonged combined oesophageal pH and manometric recordings of the pharynx, LOS, and stomach were performed using a pH glass electrode and a multiple lumen assembly incorporating a Dent sleeve connected to a portable water perfused manometric system.
RESULTS—LOS pressure varied during the day. Postprandial LOS pressures were lower than those recorded preprandially (1.2 v 1.8 kPa; p=0.005) and basal LOS pressures were significantly higher during phase III of the migrating motor complex than during the subsequent phase I (3.3 v 1.8 kPa; p=0.028). Complete LOS relaxations were occasionally observed in seven patients (0.48/h). Complete LOS relaxations were longer in duration than incomplete LOS relaxations (10.8 v 2.8 s; p=0.01) and 57% of complete relaxations fulfilled the criteria of a transient LOS relaxation (TLOSR). Complete LOS relaxations were associated with oesophageal pressure waves with higher amplitudes and longer durations. In addition, a higher proportion of these oesophageal pressure waves were spontaneous (55.6% v 0%; p<0.02) and multipeaked (72.7% v 0%). During prolonged manometry, high amplitude oesophageal pressure waves (>10 kPa) were recorded in six patients and retrograde oesophageal pressure waves in four, phenomena which were not observed during short term manometry.
CONCLUSION—In contrast with short term stationary manometry, prolonged manometry in achalasia patients revealed the occurrence of complete LOS relaxations, TLOSRs, variations in LOS pressure associated with a meal or phase III, and high amplitude and retrograde

    To date very few studies with small sample size have compared peroral esophageal myotomy (POEM) with the current surgical standard of care, laparoscopic Heller myotomy (LHM), in terms of efficacy and safety, and no recommendations have been proposed.To investigate the efficacy and safety of POEM compared with LHM, for the treatment of achalasia.The databases of Pubmed, Medline, Cochrane, and Ovid were systematically searched between January 1, 2005 and January 31, 2015, with the medical subject headings (MeSH) and keywords "achalasia," "POEM," "per oral endoscopic myotomy," and "peroral endoscopic myotomy," "laparoscopic Heller myotomy" (LHM), "Heller myotomy."All types of study designs including adult patients with diagnosis of achalasia were selected. Studies that did not report the comparison between endoscopic and surgical treatment, experimental studies in animal models, single case reports, technical reports, reviews, abstracts, and editorials were excluded.The total number of included patients was 486 (196 in POEM group and 290 in LHM group).There were no differences between POEM and LHM in reduction in Eckardt score (MD = -0.659, 95% CI: -1.70 to 0.38, P = 0.217), operative time (MD = -0.354, 95% CI: -1.12 to 0.41, P = 0.36), postoperative pain scores (MD = -1.86, 95% CI: -5.17 to 1.44, P = 0.268), analgesic requirements (MD = -0.74, 95% CI: -2.65 to 1.16, P = 0.445), and complications (OR = 1.11, 95% CI: 0.5-2.44, P = 0.796). Length of hospital stay was significantly lower for POEM (MD = -0.629, 95% CI: -1.256 to -0.002, P = 0.049). There was a trend toward significant reduction in symptomatic gastroesophageal reflux rate in favors of LHM compared to POEM group (OR = 1.81, 95% CI: 1.11-2.95, P = 0.017).All included studied were not randomized.

    Patients with bilateral pheochromocytoma often require an adrenalectomy. Autotransplantation of the adrenal cortex is an alternative therapy that could potentially be performed instead of receiving glucocorticoid replacement following adrenalectomy. Adrenal cortex autotransplantation aims to avoid the side effects of long‑term steroid treatment and adrenal insufficiency. Although the function of the hypothalamo‑hypophysial system is critical for patients who have undergone adrenal cortex autotransplantation, the details of that system, with the exception of adrenocorticotropic hormone in the subjects with adrenal autotransplantation, have been overlooked for a long time. To clarify the precise effect of adrenal autotransplantation on the pituitary gland and hypothalamus, the current study examined the gene expression of hormones produced from the hypothalamus and pituitary gland. Bilateral adrenalectomy and adrenal autotransplantation were performed in 8 to 9‑week‑old male rats. The hypothalamus and pituitary tissues were collected at 4 weeks after surgery. Transcriptional regulation of hypothalamic and pituitary hormones was subsequently examined by reverse transcription‑quantitative polymerase chain reaction. Proopiomelanocortin, glycoprotein hormone α polypeptide, and thyroid stimulating hormone β were significantly elevated in the pituitary gland of autotransplanted rats when compared with sham‑operated rats. In addition, there were significant differences in the levels of corticotropin releasing hormone receptor 1 (Crhr1), Crhr2, nuclear receptor subfamily 3 group C member 1 and thyrotropin releasing hormone receptor between the sham‑operated rats and autotransplanted rats in the pituitary gland. In the hypothalamus, corticotropin releasing hormone and urocortin 2 mRNA was significantly upregulated in autotransplanted rats compared with sham‑operated rats. The authors identified significant alterations in the function of not only the

    Preoperative preparation of the patients with adrenal cortex dysfunction is based on the careful preoperative evaluation of the type and the severity of the disturbance. The dysfunction involving adrenal glands may be: insufficiency (severe, mild, expressed) and hyperfunction (hypercorticism and/or hyperaldosteronism). If we speak about the patients with limited adrenal reserve (Addison's disease, therapeutic glucocorticoid application etc.) they need necessary corticosteroid supplementation, during preoperative preparation, as well as, during complete perioperative period. Doses needed for the substitution are adjusted according to the severity of adrenal insufficiency and according to the extent of the planned surgical procedure. Patients with Cushing's syndrome (or other form of hypercorticism), as well as, patients with Conn's syndrome (or other forms of hyperaldosteronism), do have numerous organ dysfunctions, that are significant in preoperative preparation, anesthesia and for the outcome of the surgical treatment. Common feature for both of the above syndromes is hydroelectrolyte disbalance, with hypokalemia, metabolic alkalosis and hypertension. Disturbances related to the adrenal cortex hyperfunction must be corrected preoperatively, in order to avoid complications. When we speak about hypokalemia it must be promptly corrected even before urgent/vital surgical procedure because it may cause severe intraoperative cardiac arrhythmia.

    Inflammation in the course of systemic inflammatory response syndrome (SIRS) or sepsis often results in dysregulation of the hypothalamic-pituitary-adrenal axis; however, the underlying mechanisms are not well understood. The adrenal gland is highly vascularized; thus, we hypothesized that endothelial dysfunction may actively participate in inflammation-related adrenal insufficiency. To address this hypothesis, we used the properties of developmental endothelial locus-1 (Del-1), which is an endothelial-derived anti-inflammatory factor that antagonizes integrin-dependent leukocyte adhesion. Here we identified that Del-1 is expressed in the adrenal gland and that its expression was down-regulated upon SIRS induction by systemic lipopolysaccharide administration. Furthermore, we observed increased leukocyte accumulation, inflammation, and higher apoptosis in the adrenal glands of Del-1-deficient mice as compared with wild-type mice. Strikingly, Del-1 deficiency was also associated with reduced corticosterone and ACTH levels 24 hours after lipopolysaccharide administration. Together, these data suggest that Del-1 may act as a gatekeeper of adrenal gland inflammation and may regulate the integrity of the hypothalamic-pituitary-adrenal axis stress response, thereby modulating adrenal (dys)function in the course of SIRS.

    The responses of young rats to left adrenalectomy or left adrenal manipulation were compared to surgical sham adrenalectomy in which adrenals were observed but not touched. At 12 h right adrenal wet weight, dry weight, DNA, RNA, and protein content were increased (P less than 0.05) after the first two operations. Left adrenal manipulation resulted in increased right adrenal weight at 12 h but no change in left adrenal weight. Sequential manipulation of the left adrenal at time 0 and the right adrenal at 12 h resulted in an enlarged right adrenal at 12 h (P less than 0.01), and an enlarged left adrenal at 24 h (P less than 0.05), showing that the manipulated gland was capable of response. Bilateral adrenal manipulation of the adrenal glands resulted in bilateral enlargement of 12 h (P less than 0.01). Taken together with previous results, these findings strongly suggest that compensatory adrenal growth is a neurally mediated reflex.

    Achalasia is a primary motility disorder with incomplete lower esophageal sphincter relaxation; it has an annual incidence of 0.11 cases per 100 000 children. Peroral endoscopic myotomy (POEM) is a new endoscopic treatment method for achalasia. Reports about POEM in pediatric patients are rare. We herein report the case of a 9-year-old female patient with achalasia who underwent POEM. The patient underwent endoscopic balloon dilatation because medication was not effective at a previous hospital; however, endoscopic balloon dilatation was not effective either. She then underwent successful POEM upon admission at our hospital. The patient was symptom-free at 2 years postoperatively with no signs of esophagitis in the absence of proton-pump inhibitor therapy.

    This review describes current knowledge on the mechanisms that underlie glucocorticoid insufficiency in sepsis and the molecular action of glucocorticoids. In patients with severe sepsis, numerous factors predispose to glucocorticoid insufficiency, including drugs, coagulation disorders and inflammatory mediators. These factors may compromise the hypothalamic-pituitary axis (i.e. secondary adrenal insufficiency) or the adrenal glands (i.e. primary adrenal failure), or may impair glucocorticoid access to target cells (i.e. peripheral tissue resistance). Irreversible anatomical damages to the hypothalamus, pituitary, or adrenal glands rarely occur. Conversely, transient functional impairment in hormone synthesis may be a common complication of severe sepsis. Glucocorticoids interact with a specific cytosolic glucocorticoid receptor, which undergoes conformational changes, sheds heat shock proteins and translocates to the nucleus. Glucocorticoids may also interact with membrane binding sites at the surface of the cells. The molecular action of glucocorticoids results in genomic and nongenomic effects. Direct and indirect transcriptional and post-transcriptional effects related to the cytosolic glucocorticoid receptor account for the genomic effects. Nongenomic effects are probably subsequent to cytosolic interaction between the glucocorticoid receptor and proteins, or to interaction between glucocorticoids and specific membrane binding sites.

    Pneumatic dilation (PD) of the lower esophageal sphincter (LES) in achalasia is a major palliative treatment. It is generally believed, although never substantiated, that therapeutic efficacy of ballooning in achalasia is the result of the disruption and tearing of the muscular layers of the LES. To clarify this issue, we investigated the frequency of muscular disruption at the LES, 24 hours after PD, by employing the endoscopic ultrasound (EUS), in a group of 43 consented patients with achalasia. Between July 2009 and March2012, 51 consecutive adult patients with tentative diagnosis of achalasia, some with recurrence of symptoms after an earlier treatment with balloon dilation, were evaluated and underwent PD, using Rigiflex balloon without major adverse effect. Out of the 51 evaluated, 43 eligible and consenting patients who underwent EUS, 24 hours after PD, using Olympus GF-UE 160 echoendoscope and an Aloka Prosound probe at 7.5 MHZ, are the subjects of this study. The EUS in 43 eligible patients revealed an intact LES in 36 (83.7%), small area of muscular disruption in 5 (11.6%) and small hematoma in 2 patients (4.6%). Our data convincingly demonstrate that the clinical effectiveness of balloon dilation in achalasia is not the result of muscular disruption, but of circumferential stretching of the LES. Our findings on the mechanism of action of PD in achalasia could result in modifying the current method of dilation for a safer procedure, by slowing the rate of inflation and allowing the sphincter to slowly stretch itself to the distending balloon.

    Achalasia is generally accepted as a condition associated with an increased risk for developing esophageal squamous cell carcinoma. In our paper, we introduced an achalasia patient combined with synchronous early esophageal neoplasms. We performed a combination of concurrent endoscopic submucosal dissection (ESD) and peroral endoscopic myotomy (POEM). No complications other than postoperative pain that needed morphine treatment for two days had occurred. Dysphagia was significantly improved. Neither reflux nor cough occurred. The short-term efficacy and safety of our case is favorable and suggests that concurrent ESD and POEM could be a treatment option to such patients. PMID:28250904

    Adrenal gland disease in ferrets is unique to this species, with clinical signs and pathophysiology different from those seen in the dog. Its prevalence is increasing; 70% of pet ferrets in the United States were affected in 2003. The exact causes of the adrenal gland changes that lead to the disease are not known. Early oophorohysterectomies and neutering, combined with the artificially prolonged photoperiod experienced by indoor pet ferrets, and a possible genetic component, may be contributing factors. Signs of adrenal gland disease include progressive hair loss, pruritus, lethargy, atrophy, and, in female ferrets, vulvar swelling. An understanding of the signs and physiologic changes is necessary for diagnosis and treatment. A review of anatomy, physiology, and current surgical and medical options is presented.

    The computed tomographic appearance of the adrenal gland was studied in 302 patients with possible endocrinologic disease and 107 patients undergoing CT for nonendocrinologic reasons. Measurements of adrenal size were also made in 100 adults with no known adrenal pathology. CT proved to be a sensitive diagnostic tool in combination with clinical studies. When blood hormone levels are increased, CT can differentiate among homogeneous organic hyperplasia, nodular hyperplasia, benign adenoma, and malignant cortical adenoma. When blood hormone levels are decreased, CT can demonstrate hypoplasia or metastatic tumorous destruction. Calcifications can be demonstrated earlier than on plain radiographs. When hormone elimination is increased, the morphologic substrate can be identified; tumorous changes can be localized and infiltration of surrounding organs recognized.

    Changes in climate, altitude and lifestyle during travel confronts patients presenting chronic respiratory insufficiency with special problems. A major challenge is related to high altitude during air travel. To limit risks, a preflight examination is necessary to ascertain respiratory status. Patients requiring oxygen therapy must ensure availability both during the flight and at the destination. Patients with asthma or chronic bronchitis must bring along a sufficient supply of usual inhalers. All patients should carry a doctor's letter describing their condition and listing medications. Using these elementary precautions, patients with chronic respiratory insufficiency can safely enjoy sightseeing and outdoor leisure activities.

    Primary ovarian insufficiency is a condition that represents impaired ovarian function on a continuum with intermittent ovulation. This condition commonly leads to premature menopause, defined as cessation of ovulation prior to the age of 40 years. Because there are potential immediate and long-term consequences of hypoestrogenism, a timely diagnosis is invaluable. This comprehensive review will discuss identifiable causes for primary ovarian insufficiency, including genetic disorders and metabolic abnormalities, as well as review current strategies for diagnosis, evaluation, and management of women with this condition.

    Immune and endocrine systems are basic regulatory mechanisms of organism and, including the nervous system, maintain the organism's homeostasis. The main immune system representatives are mononuclear cells, T- and B-cells and their products, in the endocrine system the main representatives are cells of the glands with inner secretion and their products. One of the most important glands for maintaining homeostasis are adrenal glands. It has been proven that either cells of the immune system, either endocrine cells can, although in trace amounts, produce mutually mediators of both systems (hormones, cytokines). Disorders in one system can lead to pathological symptoms in the other system. Also here represent adrenals an important model.

    Esophageal emptying assessed at the 'timed barium' esophagogram correlates well with symptomatic outcomes after pneumatic dilation for esophageal achalasia, although 30% of patients with satisfactory outcome exhibit partial improvement in emptying. The aim of the study was to investigate any correlation of esophageal emptying to symptomatic response after laparoscopic Heller's myotomy and Dor's fundoplication. 'Bread and barium' (transit time of a barium opaque bread bolus) and 'timed barium' (height of esophageal barium column 5 minutes after ingestion of 200-250 mL of barium suspension) esophagogram was used to assess esophageal emptying in 73 patients with esophageal achalasia before 1 and 5 years (31 cases) after laparoscopic myotomy and anterior fundoplication. Symptoms assessment was based to a specific score. At 1-year follow-up, excellent and good symptomatic results were obtained in 95% of the cases. Esophageal maximum diameter, esophageal transit time, and esophageal barium column were significantly correlated to each other and to symptom score postoperatively (P < 0.001). Complete and partial (<90% and 50-90% postoperative reduction in barium column, respectively) emptying was seen in 55% and 31% of patients with excellent result. Patients with a pseudodiverticulum postoperatively had a more delayed esophageal emptying than those without. Symptomatic outcome and esophageal emptying did not deteriorate at 5-year follow-up. Esophageal emptying assessed by 'barium and bread' and 'timed barium' esophagogram correlated well with symptomatic outcome after laparoscopic myotomy for esophageal achalasia. Complete symptomatic relief does not necessarily reflect complete esophageal emptying. Outcomes do not deteriorate by time. Because of wide availability, esophagogram can be applied in follow-up of postmyotomy patients in conjunction with symptomatic evaluation.

    Abstract Background: Achalasia is an esophageal motility disorder, of unknown cause, which results in increased lower esophageal sphincter tone and symptoms of difficulty swallowing. Current major therapeutic options include laparoscopic Heller myotomy (LHM) and pneumatic dilation (PD). We undertake a systematic review comparing the efficacy and safety of these 2 treatments in the treatment of esophageal achalasia. Methods: PubMed, Embase, and Cochrane Central Register of Controlled Trials were searched for randomized controlled trial investigating LHM versus PD in the treatment of primary achalasia. The primary outcome was symptom remission rates. The Mantel–Haenszel method with fixed-effect or random-effects model was used to calculate relative risks and 95% confidence intervals (CIs). Results: Five studies involving 498 participants were included. The cumulative remission rate was significantly higher with LHM at 3 months and 1 year (short-term), with a risk ratio of 1.16 (95% CI 1.01–1.35, P = 0.04) and 1.14 (95% CI 1.02–1.27, P = 0.02), respectively. There were no significant differences between LHM and PD in 2-year and 5-year remission rate (long-term), with a risk ratio of 1.05 (95% CI 0.91–1.22, P = 0.49) and 1.17 (95% CI 0.84–1.64, P = 0.34), respectively. Rates of major mucosal tears requiring subsequent intervention with LHM were significantly lower than those of esophageal perforation with PD requiring postprocedural medical or surgical therapy, with a risk ratio of 0.25 (95% CI 0.08–0.81, P = 0.02). Postprocedural rates of gastroesophageal reflux, lower esophageal sphincter pressures, and quality of life scores did not differ in trials with sufficient data. Conclusions: There were no significant differences between LHM and PD in 2-year and 5-year remission rate. This study indicates that either treatment can be proposed as initial treatment for achalasia. PMID:28207499

    Important new advances were presented in esophageal disease in Digestive Disease Week 2013. A highlight was confirmation of the high efficacy of weight loss to treat symptoms of reflux and an interesting pilot study suggesting that a simple ligature with supra- and infracardial bands could be an effective technique in esophageal reflux. If the excellent results and safety and efficacy of this technique are confirmed in the long term, it could revolutionize the management of gastroesophageal reflux disease. Also of note this year was the presentation of multiple studies validating a new technique, peroral endoscopic myotomy (POEM) for the endoscopic treatment of achalasia. This technique seems to have excellent efficacy and safety.

Subsequent cine mode images of esophageal emptying demonstrated abnormalities of the body of the esophagus not reflected by the manometric examination. Computer-generated time-activity curves representing specific regions of interest were better than manometry in evaluating the results of myotomy, dilatation, and drug therapy. Isosorbide dinitrate significantly improved esophageal emptying.

    Adrenal gland surgery needs a multidisciplinary team including endocrinologist, radiologist, anesthesiologist, and surgeon. The indications for adrenal gland surgery include hormonal secreting and non-hormonal secreting tumors. Adrenal hormonal secreting tumors present to the anesthesiologist unique challenges requiring good preoperative evaluation, perioperative hemodynamic control, corrections of all electrolytes and metabolic abnormalities, a detailed and careful anesthetic strategy, overall knowledge about the specific diseases, control and maintaining of postoperative adrenal function, and finally a good collaboration with other involved colleagues. This review will focus on the endocrine issues, as well as on the above-mentioned aspects of anesthetic management during hormone secreting adrenal gland tumor resection. PMID:25368694

    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 (CA) biosynthesis and secretion, is peculiar in HF and sympatholytic treatments (as β-blockers) are presently being used 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 β ARs (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 α2AR 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 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 HF pathophysiology and in the identification of new therapeutic targets.

    Adrenal oncocytoma is an extremely rare neoplasm, which is mostly non-functional. Only five cases of childhood adrenal oncocytoma have been described so far, all of which were hormonally active. Currently, guidelines for management and follow-up are not available. We report a 9-year-old girl with benign adrenal oncocytoma, presenting with severe short-term virilization. After diagnostic work-up the patient underwent laparoscopic unilateral adrenalectomy. For the first 2 weeks following surgery she suffered marked mood swings, irritability and fatigue. There were no other clinical and/or laboratory abnormalities except the rapid drop-down of androgen levels to normal values. Follow-up showed no signs of recurrence and in the absence of signs of adrenal insufficiency, we speculate that, the rapid drop of androgen levels after removal of the tumor might be the reason for the deteriorated psychoemotional condition of our patient.

    We investigated the postnatal pattern of changes in adrenal size in very low-birth-weight (VLBW) infants and its relation to late-onset glucocorticoid-responsive circulatory collapse (LGCC) that may be associated with adrenal insufficiency. In 36 VLBW infants born at <33 weeks' gestation, ultrasound examinations of postnatal changes in adrenal size during the first 3 weeks of life were performed. VLBW infants were classified into three groups: group A (N = 6), the actual adrenal area was greater than or equal to the predicted value at birth and unchanged at 3 weeks; group B (N = 24), the actual adrenal area was greater than or equal to the predicted value and decreased at 3 weeks; and group C (N = 6), the actual adrenal area was less than the predicted value and unchanged at 3 weeks. Five infants developed LGCC, and all five were in group A. These observations suggest that the life of the adrenal fetal zone might be extended beyond 3 weeks after birth in some VLBW infants and that prolonged fetal zone activity might correlate with LGCC. On the other hand, adrenal maturation might have already occurred at birth in some VLBW infants. Sonographic evaluation of adrenal size may enable prediction of subsequent LGCC in VLBW infants.

    Adrenal hemorrhage is a largely uncommon condition typically caused by a number of factors including infection, MI, CHF, anticoagulants, trauma, surgery, and antiphospholipid syndrome. Yet, idiopathic bilateral hemorrhage is rare. The authors present a case of a 63-year-old male who presented with abdominal pain that was eventually diagnosed as bilateral adrenal hemorrhages due to an unknown origin. Abdominal CT revealed normal adrenal glands without enlargement, but an MRI displayed enlargement due to hemorrhage in both adrenals. There was no known cause; the patient had not suffered from an acute infection and was not on anticoagulants, and the patient's history did not reveal any of the other known causative factors. The case underscores the importance of keeping bilateral adrenal hemorrhages on the list of differentials even when a cause is not immediately clear. It also raises the question of whether CT is the most sensitive test in the diagnosis of adrenal hemorrhage and whether the diagnostic approach should place greater weight on MRI. The case highlights the need for prompt therapy with steroids once bilateral hemorrhage is suspected to avert the development or progression of adrenal insufficiency. PMID:25973281

    1. By means of a critical review we tried to establish whether there is evidence from controlled trials in humans on the efficacy of Ginkgo biloba extracts in cerebral insufficiency. 2. The methodological quality of 40 trials on Ginkgo and cerebral insufficiency was assessed using a list of predefined criteria of good methodology, and the outcome of the trials was interpreted in relation to their quality. A comparison of the quality was made with trials of co-dergocrine, which is registered for the same indication. 3. There were eight well performed trials out of a total of 40. Shortcomings were limited numbers of patients included, and incomplete description of randomization procedures, patient characteristics, effect measurement and data presentation. In no trial was double-blindness checked. Virtually all trials reported positive results, in most trials the dosage was 120 mg Ginkgo extract a day, given for at least 4-6 weeks. For the best trials, there were no marked differences in the quality of the evidence of the efficacy of Ginkgo in cerebral insufficiency compared with co-dergocrine. The results of the review may be complicated by a combination of publication bias and other biases, because there were no negative results reported in many trials of low methodological quality. 4. Positive results have been reported for Ginkgo biloba extracts in the treatment of cerebral insufficiency. The clinical evidence is similar to that of a registered product which is prescribed for the same indication. However, further studies should be conducted for a more detailed assessment of the efficacy. PMID:1457269

    A lot of data has been accumulated at present on the metabolic and nutritional insufficiency in patients with chronic heart failure (CHF). Researchers have noted an actuality of the study of nutritional and metabolic insufficiency in CHF patients as independent factors affecting the course of CHF and because of its relationship with triggers of inflammation, sympathetic-adrenal system, and markers of functional state of the cardiovascular system (CVS). In some works attention has been given to relationship of nutritional and metabolic insufficiency with autonomic regulation of cardiac rhythm. Attempts have been made to systematize obtained data, create contemporary pathophysiological portrait of CHF development and highlight prevailing mechanisms of progression of the disease. This review summarizes accumulated data on nutritional insufficiency in patients with CHF and systematizes metabolic changes according to types of metabolism and CHF functional class. We have also made an attempt of creating figurative representation of pathophysiological mechanism of development of nutritional insufficiency in CHF. We have emphasized the problem of inadequate knowledge on contribution of inflammatory markers in development of nutritional insufficiency especially in patients with I-II functional classes of CHF. We also present suggestions concerning strategy of studying nutritional insufficiency in CHF, its classification according to CHF functional class, stratification of risk factors of its development, and the methods of its prevention and correction.

    Peroral endoscopic myotomy (POEM) has been developed as a minimally invasive endoscopic treatment for achalasia for years. However, the optimal length of submucosal tunnel and myotomy of muscle bundles during procedure of POEM has not yet been determined, so we aim to assess safety and efficacy of modified POEM with shorter myotomy of muscle bundles in achalasia patients. Consecutive achalasia patients had been performed modified POEM with shorter myotomy, and assessed by symptoms, high-resolution manometry, and barium swallow examinations before and 3 months after POEM for safety and efficacy evaluation. Modified POEM with shorter submucosal tunnel (mean length 6.8 cm) and endoscopic myotomy of muscle bundles (total mean length 5.4 cm) were completed in 46 consecutive achalasia patients. During the 3-month follow up in all cases, significant improvement of symptoms (a significant drop in the Eckardt score 8.4 ± 3.2 vs. 2.7 ± 1.9; P < 0.001), decreased lower esophageal sphincter pressure (39.4 ± 10.1 vs. 24.4 ± 9.1 mmHg; P < 0.001) and integrated relaxation pressure (38.6 ± 10.4 vs. 25.7 ± 9.6 mmHg; P < 0.01), and a drop in height of esophagus barium-contrast column (5.4 ± 3.1 vs. 2.6 ± 1.8 cm; P < 0.001) were observed. The frequencies of adverse events were lower in those under endotracheal anesthesia and CO2 insufflations compared with intravenous anesthesia and air insufflations. Only three patients were found to have gastroesophageal reflux disease on follow up. Modified POEM with shorter myotomy under endotracheal anesthesia and CO2 insufflations shows its good safety and excellent short-term efficacy in the treatment of achalasia. But further studies are warranted to assess the long-term efficacy.

    AIM: To assess and compare the esophageal function after peroral endoscopic myotomy (POEM) vs other conventional treatments in achalasia. METHODS: Chart review of all achalasia patients who underwent POEM, laparoscopic Heller myotomy (LHM) or pneumatic dilation (PD) at our institution between January 2012 and March 2015 was performed. Patient demographics, type of achalasia, prior treatments, pre- and post-treatment timed barium swallow (TBE) and high-resolution esophageal manometry (HREM) findings were compared between the three treatment groups. Patients who had both pre- and 2 mo post-treatment TBE or HREM were included in the final analysis. TBE parameters compared were barium column height, width and volume of barium remaining at 1 and 5 min. HREM parameters compared were basal lower esophageal sphincter (LES) pressures and LES-integrated relaxation pressures (IRP). Data are presented as mean ± SD, median [25th, 75th percentiles] or frequency (percent). Analysis of variance, Kruskal-Wallis test, Pearsons χ2 test and Fishers Exact tests were used for analysis. RESULTS: A total of 200 achalasia patients were included of which 36 underwent POEM, 22 underwent PD and 142 underwent LHM. POEM patients were older (55.4 ± 16.8 years vs 46.5 ± 15.7 years, P = 0.013) and had higher BMI than LHM (29.1 ± 5.9 kg/m2 vs 26 ± 5.1 kg/m2, P = 0.012). More number of patients in POEM and PD groups had undergone prior treatments compared to LHM group (72.2% vs 68.2% vs 44.3% respectively, P = 0.003). At 2 mo post-treatment, all TBE parameters including barium column height, width and volume remaining at 1 and 5 min improved significantly in all three treatment groups (P = 0.01 to P < 0.001) except the column height at 1 min in PD group (P = 0.11) . At 2 mo post-treatment, there was significant improvement in basal LES pressure and LES-IRP in both LHM (40.5 mmHg vs 14.5 mmHg and 24 mmHg vs 7.1 mmHg respectively, P < 0.001) and POEM groups (38.7 mmHg vs 11.4 mmHg and 23.6 mm

    To find a simple method to screen for iatrogenic childhood adrenal insufficiency, we retrospectively examined the results of CRH stimulation tests performed 212 times on 111 subjects (68 males; age at commencement of initial treatment ranged 0.0-19.8 yr; median age, 5.8 yr). Before the commencement of this study, 97 subjects had been treated with glucocorticoids and 14 subjects with West syndrome had been treated with synthetic adrenocorticotropic hormone. Duration of the primary treatment ranged from 15 to 2150 days. CRH stimulation tests were conducted between 09:00 AM and 10:00 AM and peak cortisol values less than 15 µg/dL were considered indicative of adrenal insufficiency. The receiver operating characteristic curve showed that the optimal basal serum cortisol cut-off values when screening for adrenal suppression ranged from 5.35 to 5.80 µg/dL depending on the primary disease. All subjects having a serum cortisol value of less than 2.3 µg/dL had insufficient adrenal function while all subjects having greater than 11 µg/dL had intact adrenal function. We concluded that single serum cortisol values obtained between 09:00 AM and 10:00 AM had the potential to serve as an index of adrenal function in children treated with glucocorticoids or synthetic adrenocorticotropic hormone.

    Apart from neuroblastomas, adrenal tumors are exceedingly rare in children and young adults. In this age group, the vast majority of patients present with clinical signs associated with excess hormone production. The most common tumor to arise from the adrenal cortex is an adrenocortical carcinoma (ACC). Similar to the situation in adults, this tumor is frequently diagnosed at a late stage and carries a very poor prognosis. ACCs require extensive/aggressive local resection followed by mitotane chemotherapy. A multidisciplinary approach is essential, and these children should be referred to units that have previous experience in managing ACCs. International registries are an invaluable source for evidence-based care, and such collaborations should be further developed in the future. Pheochromocytomas are derived from the adrenal medulla and present with symptoms caused by high secretion of catecholamines. At least one-third of these children will be found to carry genetic mutations, most commonly the RET gene (MEN2 syndrome) or the VHL gene. Open radical adrenalectomy should be offered to children with adrenocortical cancers. For all other cases, laparoscopic adrenalectomy is the treatment of choice. It is possible that the retroperitoneoscopic approach will gain increasing favor. The role of robotic adrenalectomy remains controversial.

    Ewing's sarcoma, also called primitive neuroectodermal tumour of the adrenal gland, is extremely rare. Only a few cases have been reported in the literature. We report on a woman with adult-onset primitive neuroectodermal tumour of the adrenal gland presenting with progressive flank pain. Computed tomography confirmed an adrenal tumour with invasion of the left diaphragm and kidney. Radical surgery was performed and the pain completely resolved; histology confirmed the presence of primitive neuroectodermal tumour, for which she was given chemotherapy. The clinical presentation of this condition is non-specific, and a definitive diagnosis is based on a combination of histology, as well as immunohistochemical and cytogenic analysis. According to the literature, these tumours demonstrate rapid growth and aggressive behaviour but there are no well-established guidelines or treatment strategies. Nevertheless, surgery remains the mainstay of local disease control; curative surgery can be performed in most patients. Adjuvant chemoirradiation has been advocated yet no consensus is available. The prognosis of patients with primitive neuroectodermal tumours remains poor.

    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.

    The human adrenal is an endocrine gland located at the superior part of the kidney. Composed of the adrenal cortex of mesoblastic origin and the adrenal medulla of neuroectoblastic origin, the human fetal adrenal grows considerably during the first three months of development. From 12 to 18 weeks of development (WD), the weight of the adrenals increases seven-fold. The gland's weight doubles from 18 to 28 WD and from 28 to 36 WD. At birth, the two adrenals weigh on average 10 g. At the 8th week, two zones are individualized in the adrenal cortex: the definitive zone and the fetal inner zone. At the second trimester, according to ultrastructural and biochemical studies, a third zone, called the transition zone, is individualized between the definitive zone and the fetal inner zone. The definitive zone persists, but the origin of the three zones (glomerular, fascicular and reticular) of adult adrenal cortex is not known. The fetal inner zone regresses from the 5th month of gestation and disappears totally one year after birth. At the 8th week, the immature neuroblasts migrate to the definitive zone, then to the fetal inner zone to compose the adrenal medulla, which develops essentially after birth and during the first year. Before the 10th week, the human fetal adrenal is able to produce steroid hormones, in particular dehydroepiandrosterone sulfate (DHEA-S); the secretion of cortisol remains discussed. The development of the human fetal adrenal is complex and is under the control of hormones (ACTH, LH and betaHCG), growth factors (ACTH essentially) and transcription factors (essentially SF1 and DAX-1). Knowledge of morphological and molecular phenomena of this development permits to understand the pathophisiology of congenital adrenal deficiencies.

    The kinetics of plasma and adrenal cholesteral equilibration were analyzed in patients undergoing bilateral adrenalectomy for generalized mammary carcinoma. A biological model is proposed to help in the understanding of adrenal cholesterol physiology. It comprises two intracellular compartments: (1) A compartment of free adrenal cholesterol which is small (of the order of 17 mg) but turns over very fast; it is renewed approximately 8 times per day: 3 times by the inflow of free plasma cholesterol, and 5 times by the hydrolysis of esterified adrenal cholesterol, the contribution of adrenal cholesterol synthesis appearing to be relatively small. (2) A compartment of esterified adrenal cholesterol which is 20 times larger; it is constantly renewed by in situ esterification and hydrolysis with a daily fractional turnover rate of the order of 0.25. The direct and selective accumulation of plasma cholesteryl esters is practically absent. Only free adrenal cholesterol returns to plasma, mostly after conversion into steroid “hormones.” However small the synthesis of adrenal cholesterol may be, it seems more important in the zona “reticularis.” On the other hand, the inflow of plasma cholesterol and the turnover of the free adrenal compartment tend to be faster in the zona “fasciculata.” The equilibration of plasma and adrenal cholesterol can proceed unmodified under conditions of ACTH suppression. In one patient with Cushing's disease the size of the two adrenal compartments was clearly increased but their equilibration with plasma cholesterol proceeded normally. In another patient the kinetics of hydrocortisone corresponded to those of free adrenal cholesterol in the control studies. PMID:4338119

  2. Premature ovarian insufficiency - fertility challenge.

    Premature ovarian insufficiency, defined as amenorrhea with estrogen deficiency in a woman younger than 40 associated with a serum follicle stimulating hormone (FSH) >35 mIU/mL, can be temporarily reversed with ovulation achieved resulting in live delivered pregnancies. Though this may occur spontaneously the frequency of ovulation can be considerably increased by various techniques of lowering the elevated serum FSH level and thus up-regulate down-regulated FSH receptors in the granulosa-theca cells. This can be accomplished by either suppressing FSH release from the pituitary by negative feedback through high dose estrogen or by suppressing FSH production by inhibiting the gonadotropin releasing hormone (GnRH) by either using GnRH agonists or antagonists. The estrogen method is the technique of choice because it is much less expensive than GnRH analogues, and helps stimulate cervical mucus and endometrial development. Ethinyl estradiol is the preferred estrogen because it does not contribute to the measurement of serum estradiol and thus allows proper monitoring of follicular maturation. Sometimes exogenous gonadotropins are needed as a boost but the dosage should be low so as not to down-regulate FSH receptors again. The technique is referred to as the FSH receptor restoration technique. Progesterone should be supplemented in the luteal phase. Physicians should be cognizant of trying to help prevent premature ovarian insufficiency by judiciously choosing less gonadotoxic cancer treatment alternatives that are equally efficacious. Also surgery for ovarian endometriomas should be performed only when absolutely necessary.

    A patient who was thought to have testicular feminization syndrome and primary aldosteronism had an adrenal scan that suggested an adrenal adenoma. After later diagnosis of 17-alpha-hydroxylase deficiency, she was treated with glucocorticoids rather than surgery. Her clinical course and a repeat adrenal scan confirmed she did not have a tumor.

    Hemorrhage of the kidneys and adrenal glands has many etiologies. In the adrenal glands, trauma, anticoagulation, stress, sepsis, surgery, and neoplasms are common causes of hemorrhage. In the kidneys, reasons for hemorrhage include trauma, bleeding diathesis, vascular diseases, infection, infarction, hemorrhagic cyst rupture, the Antopol-Goldman lesion, and neoplasms. Angiomyolipoma and renal cell carcinoma are the neoplasms most commonly associated with hemorrhage in the kidneys and adrenal cortical carcinoma, metastases, and pheochromocytoma are associated with hemorrhage in the adrenal glands. Understanding the computed tomography and magnetic resonance imaging features, and causes of hemorrhage in the kidneys and adrenal glands is critical. It is also important to keep in mind that mimickers of hemorrhage exist, including lymphoma in both the kidneys and adrenal glands, and melanoma metastases in the adrenal glands. Appropriate imaging follow-up of renal and adrenal hemorrhage should occur to exclude an underlying malignancy as the cause. If there is suspicion for malignancy that cannot be definitively diagnosed on imaging, surgery or biopsy may be warranted. Angiography may be indicated when there is a suspected underlying vascular disease. Unnecessary intervention, such as nephrectomy, may be avoided in patients with benign causes or no underlying disease. Appropriate management is dependent on accurate diagnosis of the cause of renal or adrenal hemorrhage and it is incumbent upon the radiologist to determine the etiology.

  5. The adrenal medulla and Parkinson's disease.

    This paper reviews the literature describing the condition of the adrenal medulla in Parkinson's disease. Parkinson's disease is a neurodegenerative disorder that is characterized primarily by the loss of dopaminergic neurons in the substantia nigra. Clinical observations have revealed that Parkinson's disease is also frequently accompanied by a variety of autonomic symptoms. The adrenal medulla is a major component of the autonomic nervous system. However, until recently this organ has not been of particular interest in Parkinson's disease. Early studies found histologic abnormalities in adrenal medullary cells, and several groups measured urinary and plasma catecholamines to determine general autonomic status. In the late 1980s adrenal medullary tissue was first transplanted to the caudate nucleus in an attempt to augment the decreased levels of dopamine, and thus treat the symptoms of Parkinson's disease. At this time the status of the adrenal medulla in this disease became clinically important. We measured the total catecholamine content of the parkinsonian adrenal medulla in tissue collected both at autopsy and in conjunction with adrenal-caudate transplants. Adrenal medullary catecholamines and several neuropeptides were severely depressed in parkinsonian glands. Thus, the adrenal medulla appears to be a target of the peripheral manifestations of Parkinson's disease.

  8. Esophageal per oral endoscopic myotomy (POEM) for achalasia: first case reported in Eastern Europe.

    PubMed

    Tantau, Marcel; Tantau, Alina

    2013-12-01

    Traditional endoscopic treatment of achalasia consists of endoscopic balloon dilatation with the inconvenience of the recurrence of symptoms and the necessity of repeated sessions. Surgical laparoscopic procedure has been advocated to be more efficient especially in young patients because it sections the lower oesophageal sphincter via a transabdominal approach. The long term most severe complication has been refractory reflux oesophagitis due mainly to the alteration of the oesogastric antireflux anatomy (Hiss angle). Surgical myotomy was clasically associated with an antireflux procedure. Peroral endoscopic myotomy (POEM) via a mucosal orifice is as efficient as surgical myotomy but the antireflux anatomy of gastroesophageal junction is not altered, so the reflux symptoms are reduced. Second, POEM is mini invasive in comparison with laparoscopic surgery. The paper presents our first and successful case of this endoscopic surgical procedure in a 41 year old patient.

    A retrospective survey was made of all the patients resident in the Nottingham area who presented with achalasia between 1959 and 1983. Initial treatment consisted of pneumatic bag dilatation in 26, hydrostatic bag dilatation in one and surgical cardiomyotomy in 22. Those treated by dilatation were older (mean age 52 years) than those treated by cardiomyotomy (mean age 42 years). Seven patients died without receiving active treatment because of old age and infirmity and in 6 this occurred before the introduction of endoscopic dilatation to the area. Initial treatment by cardiomyotomy was associated with a lower recurrence rate than treatment by bag dilatation but with a longer stay in hospital and a higher incidence of complications including empyema, chest infections and oesophageal stricture.

    Abnormal eating behaviour among psychiatric patients is associated with several psychiatric conditions, but may also be caused by a comorbid physical condition. Clinical assessment of a psychiatric patient is often challenging, which contributes to an increased rate of undiagnosed medical conditions and an increased mortality rate. We present the clinical case of a 46-year-old woman with a long-term delusion of triplet pregnancy, and recurrent vomiting. She experienced intense weight loss and eventually faced a life-threatening situation due to achalasia, which was incidentally discovered on a chest X-ray during her second psychiatric hospitalization, after several other tests, including upper digestive endoscopy, returned normal results. After a successful laparoscopic Heller's myotomy, her digestive symptoms greatly improved. This report illustrates the difficulty of establishing clinical-surgical diagnoses in psychotic patients, as some delusions seem to explain clinical complaints, masking and delaying the diagnosis of comorbid conditions.

    Congenital adrenal hyperplasia due to 21-hydroxylase deficiency is an autosomal recessive disorder caused by mutations in the CYP21A2 gene. Cortisol and aldosterone synthesis are impaired in the classic forms (adrenal insufficiency and salt-wasting crisis). Females affected are virilised at birth, and are at risk for genital ambiguity. In this article we give recommendations for an early as possible diagnosis and an appropriate and individualised treatment. A patient and family genetic study is essential for the diagnosis of the patient, and allows genetic counselling, as well as a prenatal diagnosis and treatment for future pregnancy.

    The effects of sublingual isosorbide dinitrate (5 mg) and nifedipine (20 mg) were compared in 15 patients with achalasia. The parameters examined included the manometric measurement of the lower esophageal sphincter pressure, the radionuclide assessment of esophageal emptying and the clinical response. The mean basal lower esophageal sphincter pressure fell significantly after both drugs (p less than 0.01), with a maximum fall of 63.5% 10 min after receiving isosorbide dinitrate, but by only 46.7% 30 min after nifedipine. The esophageal radionuclide test meal retention was significantly less (p less than 0.01) only after receiving isosorbide dinitrate. The drug improved initial esophageal emptying by its effect on the lower esophageal sphincter and by relieving the test meal hold-up noted to occur at the junction of the upper and midesophagus. Eight patients cleared their test meal within 10 min after isosorbide dinitrate administration while only two did so after nifedipine. Subjectively, 13 patients had their dysphagia relieved by isosorbide dinitrate and 8 by nifedipine. However, this relief was not confirmed in 4 patients by the radionuclide study and they, as well as the other 3 patients who did not respond to therapy, were referred to pneumatic dilatation. Side effects were more prominent after nitrates. Three of the patients are currently receiving nifedipine and 5 patients received isosorbide dinitrate therapy for 8-14 mo. The radionuclide test meal is currently the best way of objectively evaluating drug therapy in patients with achalasia. Isosorbide dinitrate is more effective than nifedipine in relieving their symptoms.

    With the accumulation of clinical trials demonstrating its efficacy and safety, peroral endoscopic myotomy (POEM) has emerged as a less invasive treatment option for esophageal achalasia compared with laparoscopic Heller myotomy. However, the difficulty in determining the exact extent of myotomy, a critical factor associated with the success and safety of the procedure, remains a limitation. Although the various endoscopic landmarks and ancillary techniques have been applied, none of these has been proven sufficient. As a solution for this limitation, the double-scope POEM technique with a second endoscope to assure the exact length of the submucosal tunnel has been applied since 2014. Before double-scope POEM was introduced, the second endoscope was applied only to confirm the accuracy of the procedure. In the present study, we performed double-scope POEM in the treatment of esophageal achalasia through a novel procedure of simultaneous application of the second endoscope to assist in the conventional POEM procedure.

    The glucocorticoid-induced inhibition that occurs after discontinuation of treatment is the most frequent cause of adrenal insufficiency. There are yet some doubts about the best way of evaluating the hypothalamic-pituitary-adrenal (HPA) axis in those patients. The main objective of this study was to evaluate the utility of basal cortisol in diagnosing adrenal insufficiency. Thirty-five children with acute lymphoid leukemia (ALL) receiving glucocorticoid therapy (median age of 6.9 years) were evaluated. A stimulus test with corticotropin releasing hormone (CRH-1 mcg/kg) was performed before the introduction of dexamethasone (6 mg/m2/day, for 28 days), in the 8th and the 28th days of glucocorticoid therapy, and 48 hours and one month after discontinuation of therapy. Suppression of the basal secretion as well as the maximum concentration of cortisol (post-CRH) occurred during glucocorticoid therapy, which persisted for 48 hours after the steroid was removed from treatment (p< 0.01 and p< 0.0001, respectively, for the three tests). One month after ceasing the administration of the glucocorticoid, the basal secretion, as well as the maximum concentration of cortisol, were similar to that before glucocorticoid therapy. There was a positive and statistically significant correlation between basal secretion and maximum concentration of cortisol in all tests. We observed 95% of specificity for the diagnosis of adrenal insufficiency when the inferior limit of basal cortisol was 8.5 mcg/dl. According to these results we concluded that basal secretion of cortisol is a good marker of supra-renal function in evaluating children after discontinuation of glucocorticoid therapy.

    Although cortisol has a distinct circadian rhythm, patients with adrenal insufficiency usually receive diurnal hydrocortisone replacement therapy (HRT), disregarding possible consequences for sleep quality. The case reported here concerns the resolution of severe insomnia in a patient with global hypopituitary insufficiency upon adjustment of triple HRT to quadruple HRT. The data show a strong influence of cortisol on total sleep time and slow wave sleep (SWS) as well as rapid eye movement (REM) sleep. Clinically, the data are suggestive of the need to assimilate HRT to the natural circadian cortisol rhythm and not restrict it to the active part of the day.

    Chronic fatigue syndrome (CFS) is defined as constellation of the prolonged fatigue and several somatic symptoms, in the absence of organic or severe psychiatric disease. However, this is an operational definition and conclusive biomedical explanation remains elusive. Similarities between the signs and symptoms of CFS and adrenal insufficiency prompted the research of the hypothalamo-pituitary-adrenal axis (HPA) derangement in the pathogenesis of the CFS. Early studies showed mild glucocorticoid deficiency, probably of central origin that was compensated by enhanced adrenal sensitivity to ACTH. Further studies showed reduced ACTH response to vasopressin infusion. The response to CRH was either blunted or unchanged. Cortisol response to insulin induced hypoglycaemia was same as in the control subjects while ACTH response was reported to be same or enhanced. However, results of direct stimulation of the adrenal cortex using ACTH were conflicting. Cortisol and DHEA responses were found to be the same or reduced compared to control subjects. Scott et al found that maximal cortisol increment from baseline is significantly lower in CFS subjects. The same group also found small adrenal glands in some CFS subjects. These varied and inconsistent results could be explained by the heterogeneous study population due to multifactorial causes of the disease and by methodological differences. The aim of our study was to assess cortisol response to low dose (1 microgram) ACTH using previously validated methodology. We compared cortisol response in the CFS subjects with the response in control and in subjects with suppressed HPA axis due to prolonged corticosteroid use. Cortisol responses were analysed in three subject groups: control (C), secondary adrenal insufficiency (AI), and in CFS. The C group consisted of 39 subjects, AI group of 22, and CFS group of nine subjects. Subject data are presented in table 1. Low dose ACTH test was started at 0800 h with the i.v. injection of 1

    In the past, a Heller myotomy was considered to be ineffective in patients with achalasia and a markedly dilated or sigmoid-shaped esophagus. Esophagectomy was the standard treatment. The aims of this study were (a) to evaluate the results of laparoscopic Heller myotomy and Dor fundoplication in patients with achalasia and various degrees of esophageal dilatation; and (b) to assess the role of endoscopic dilatation in patients with postoperative dysphagia. One hundred and thirteen patients with esophageal achalasia were separated into four groups based on the maximal diameter of the esophageal lumen and the shape of the esophagus: group A, diameter<4.0 cm, 46 patients; group B, esophageal diameter 4.0-6.0 cm, 32 patients; group C, diameter>6.0 cm and straight axis, 23 patients; and group D, diameter>6.0 cm and sigmoid-shaped esophagus, 12 patients. All had a laparoscopic Heller myotomy and Dor fundoplication. The median length of follow-up was 45 months (range 7 months to 12.5 years). The postoperative recovery was similar among the four groups. Twenty-three patients (20%) had postoperative dilatations for dysphagia, and five patients (4%) required a second myotomy. Excellent or good results were obtained in 89% of group A and 91% of groups B, C, and D. None required an esophagectomy to maintain clinically adequate swallowing. These data show that (a) a laparoscopic Heller myotomy relieved dysphagia in most patients with achalasia, even when the esophagus was dilated; (b) about 20% of patients required additional treatment; (c) in the end, swallowing was good in 90%.

    Peroral endoscopic myotomy (POEM) has been widely applied to the treatment of achalasia. The aim of this study is to retrospectively investigate the long-term outcome of POEM in patients with achalasia. Patients undergoing POEM at our center with a minimum follow-up of 3 years were enrolled in this study. Relief of patients' symptom was defined as the primary outcome. Secondary outcomes included lower esophageal sphincter pressure, esophageal emptying, symptoms relapse, and clinical reflux adverse events. The Chi-square test was performed to determine the potential predictors of surgical failure. Sixty-seven patients (aged 40.7 ± 15.3 years) were recruited in the study, with a mean follow-up period of 40.1 ± 2.8 months. At the final follow-up, the median Eckardt score reduced from 7.6 ± 2.3 preoperatively to 1.9 ± 1.7 (P < 0.001), the lower esophageal sphincter pressure was reduced from 35.4 ± 13.7 mmHg preoperatively to 8.9 ± 4.1 mmHg (P < 0.001), and the height of the barium column at 5 min after barium swallowed was reduced from 9.7 ± 1.6 cm preoperatively to 2.9 ± 2.1 cm (P < 0.001). Eight patients had symptoms relapse and nine patients developed reflux esophagitis. Type III achalasia was found to be indicative of surgical failure. POEM was a promising treatment for patients with achalasia, which can yield a long-term relief of the symptom and a low rate of clinical reflux adverse events.

    Moyamoya disease (MMD) is a progressive vasculopathy characterized by occlusion of the terminal portion of the internal carotid arteries and its branches, and the formation of compensatory moyamoya collateral vessels. Homozygous mutations in GUCY1A3 have been reported as a cause of MMD and achalasia. Probands (n = 96) from unrelated families underwent sequencing of GUCY1A3. Functional studies were performed to confirm the pathogenicity of identified GUCY1A3 variants. Two affected individuals from the unrelated families were found to have compound heterozygous mutations in GUCY1A3. MM041 was diagnosed with achalasia at 4 years of age, hypertension and MMD at 18 years of age. MM149 was diagnosed with MMD and hypertension at the age of 20 months. Both individuals carry one allele that is predicted to lead to haploinsufficiency and a second allele that is predicted to produce a mutated protein. Biochemical studies of one of these alleles, GUCY1A3 Cys517Tyr, showed that the mutant protein (a subunit of soluble guanylate cyclase) has a significantly blunted signaling response with exposure to nitric oxide (NO). GUCY1A3 missense and haploinsufficiency mutations disrupt NO signaling leading to MMD and hypertension, with or without achalasia.

    Purpose: To assess the short-term efficacy and quality of life (QOL) of patients with achalasia after peroral endoscopic myotomy (POEM). Methods: Thirty-five achalasia patients underwent POEM from May 2013 to December 2013. The data on clinical evaluation and QOL before therapy, at 1 month and 6 months postoperation were collected and analyzed. Results: All the thirty-five patients underwent POEM successfully. By comparing the data of the preoperative with that of 1 month and 6 months after POEM respectively, we found that: mean Eckardt score decreased (6.83 vs 0.51, 6.83 vs 0.46, all P <0.05), esophagus diameter reduced (47.97 mm vs 32.00 mm, 47.97 mm vs 28.50 mm, all P <0.05), and esophageal manometry declined (29.5 mmHg vs 11.5 mmHg, 29.5 mmHg vs 10.3 mmHg, all P <0.05). Complications occurred in 14.3% (5/35) of the cases, and no recurrence was observed. At each time point, postoperative QOL scores were higher than those of preoperative (P <0.05). Conclusions: POEM is safe and effective for treating achalasia in the short-term, it can relieve clinic symptoms as well as improve patients’ QOL. PMID:26156194

    2012-04-01

    Achalasia is a rare disease of the esophagus, characterized by the absence of peristalsis in the esophageal body and incomplete relaxation of the lower esophageal sphincter, which may be hypertensive. The cause of this disease is unknown; therefore, the aim of the therapy is to improve esophageal emptying by eliminating the outflow resistance caused by the lower esophageal sphincter. This goal can be accomplished either by pneumatic dilatation or surgical myotomy, which are the only long-term effective therapies for achalasia. Historically, pneumatic dilatation was preferred over surgical myotomy because of the morbidity associated with a thoracotomy or a laparotomy. However, with the development of minimally invasive techniques, the surgical approach has gained widespread acceptance among patients and gastroenterologists and, consequently, the role of surgery has changed. The aim of this study was to review the changes occurred in the surgical treatment of achalasia over the last 2 decades; specifically, the development of minimally invasive techniques with the evolution from a thoracoscopic approach without an antireflux procedure to a laparoscopic myotomy with a partial fundoplication, the changes in the length of the myotomy, and the modification of the therapeutic algorithm.

    Purpose of Review Journal articles relevant to the diagnosis and treatment of velopharyngeal insufficiency (VPI) were reviewed. All articles ascertained by PubMed search were included. Recent Findings Articles reported on the application of magnetic resonance scanning, reliability tests of the International Working Group diagnostic protocol, the use of nasometry, and techniques designed to assess the function of the velopharyngeal mechanism. Treatment papers focused on outcomes in small samples of cases and complication rates from pharyngeal flap. One paper discussed ineffective speech therapy procedures. Summary There were relatively few papers this past year. Those that were published were hindered by small and heterogeneous sample sizes, and occasionally by inappropriate methods for assessing outcomes. None of the findings will have a major impact on the current state-of-the-art for diagnosis of VPI. The speech therapy paper has a very important message that should be taken to heart by all clinicians involved in the management of children with clefts and craniofacial disorders. PMID:19448542

POI relevance is continuously growing because of the increasing number of women desiring conception beyond 30 years of age, when POI prevalence is >1%. POI is highly heterogeneous and can present with ovarian dysgenesis and primary amenorrhea, or with secondary amenorrhea, and it can be associated with other congenital or acquired abnormalities. In most cases POI remains classified as idiopathic. However, the age of menopause is an inheritable trait and POI has a strong genetic component. This is confirmed by the existence of several candidate genes, experimental and natural models. The variable expressivity of POI defect may indicate that, this disease may frequently be considered as a multifactorial or oligogenic defect. The most common genetic contributors to POI are the X chromosome-linked defects. Here, we review the principal X-linked and autosomal genes involved in syndromic and non-syndromic forms of POI with the expectation that this list will soon be upgraded, thus allowing the possibility to predict the risk of an early age at menopause in families with POI.

    Introduction: Adrenal disorders could be a life-threatening emergency, hence requires immediate therapeutic management. For this awareness regarding its diagnosis, management, and treatment is prime important. Aims and Objective: To study the awareness of adrenal disorders among interns and postgraduates students of Hamidia Hospital, Bhopal. Materials and Methods: A cross-sectional questionnaire-based study was performed. Fifty-six participants, i.e., 1st, 2nd, and 3rd years postgraduate residents of general medicine (n = 14 × 3) and interns (n = 14) were included in the study. There were 12 questions on adrenal insufficiency, adrenal adenoma, congenital adrenal hyperplasia (CAH), nonclassical CAH (NCCAH), pheochromocytoma, and Conn's syndrome. One mark was awarded for each correct response. Results: In the present study, 14 (25%) participants scored < 5 marks, 33 (58.9%) scored between 6 and 9, and 9 (16.1%) scored between 10 and 12. The mean score among the participants was 6.38 ± 2.505, with a range from 2 to 11 marks. The number of correct answers by postgraduates residents of 1st year was 101, 2nd year was 95, and 3rd year was 93 and interns scored 68 out of total 168 questions in each group. Mean awareness score for residents of 1st, 2nd, 3rd years participants and interns was 7.21 ± 2.806, 6.79 ± 2.119, and 6.64 ± 2.818 and 6.63 ± 2.505, respectively. Most of the participants recorded correct responses related to diagnosis (57.7%) followed by responses related to treatment (64.3%). Answers to a question regarding how commonly is adrenal insufficiency diagnosed in medical Intensive Care Unit, none of the individuals responded correctly. Conclusion: There was a lack of awareness regarding diagnosis, management, and treatment of adrenal disorders in central India. We need to prioritize training related to these illnesses in our postgraduate teaching curriculum in practice. PMID:28217529

    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.

    Corticomedullary mixed tumors of the adrenal gland are quite rare, with only five well-documented cases reported in the literature.(1-4) Herein, we report the light microscopic and immunohistochemical features of two cases of this rare tumor. Patient 1 is a 34-year-old woman who presented with hypertension, hair loss, and amenorrhea of 1-year duration. Patient 2 is a 52-year-old woman who presented with flank pain and what appeared to be a renal mass on arteriogram with no history of hypertension, Cushing's syndrome, or other endocrine abnormalities. At surgery, the tumor was noted to arise from the adrenal gland rather than the kidney and adrenalectomy was performed. In both cases, the surgically resected specimens consisted of a well-circumscribed, single adrenal mass surrounded by a rim of uninvolved adrenal cortical tissue. The tumors were composed of adrenal cortical cells intimately admixed with pheochromocytes. Immunohistochemical studies highlighted these two cellular components. The pheochromocytes were strongly reactive with chromogranin and the sustentacular cells with S-100 protein, whereas the adrenal cortical cells reacted specifically with inhibin. Thus, we report two additional cases of mixed corticomedullary tumor of the adrenal gland. Ann Diagn Pathol 5:304-308, 2001. This is a US government work. There are no restrictions on its use.

    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.

    Eosinophilic esophagitis (EoE) is now recognized as a common cause of dysphagia. Eosinophilic infiltration of the esophagus has also been associated with other conditions, such as gastroesophageal reflux disease (GERD); however, the incidence, pattern, and clinical significance of eosinophilic infiltration in achalasia are poorly documented. We sought to characterize this histological finding in patients undergoing Heller myotomy (HM) for achalasia. Ninety-six patients undergoing laparoscopic HM for primary achalasia between 1999 and 2008 were identified from a prospective database. Serial mid and distal per-endoscopic esophageal biopsies taken from patients before and after surgery were assessed for the presence of elevated intraepithelial eosinophils (EIEs). Slides from patients with reports suggestive of EIE were reviewed independently by two pathologists, and the highest eosinophil count/high-power field (eos/hpf) was recorded. Dysphagia scores (0 = none to 5 = severe dysphagia), GERD health-related quality of life scores (0 = best to 45 = worst), and 24-hour pH results were compared before and 3 months after surgery. We related the highest eos to the symptoms and response to HM. Data are presented as median (range). Paired t-test and Wilcoxon signed-rank test determined significance, *P < 0.05. Of 96 patients with achalasia, 50 had undergone pre-HM biopsies revealing EIE in 17/50 (34%), with a median of 3 eos/hpf (1-21). Two patients were found to have superimposed esophageal candidiasis. One patient met the pathologic criteria for EoE. Twenty-five of 50 (50%) postoperative biopsies demonstrated a median of 5 eos/hpf (1-62) for a total of 28/50 patients (56%) with EIE in either the preoperative or postoperative period. Four patients (8%) met the pathologic criteria for EoE, and two demonstrated persistent esophageal candidiasis. A decrease in eosinophils was found in 6/28 patients (21%) from 3/hpf (1-21) to 0.5/hpf (0-4). Increase in eosinophils was found in

    A 56-year-old woman presented with an incidental adrenal adenoma and physical examination findings that included moderate obesity, a slight cervicothoracic fat pad ("buffalo hump"), increased supraclavicular fat pads, and white abdominal striae. Biochemical workup revealed elevated levels of 24-hour urinary free cortisol but normal serum morning cortisol and suppressed levels of corticotropin, suggestive of adrenal-dependent Cushing syndrome. The resected adrenal gland revealed macronodular cortical hyperplasia with a dominant nodule. Other findings included an absent cortisol response to corticotropin stimulation, presence of serum anti-21-hydroxylase antibodies, and mononuclear cell infiltration--consistent with adrenalitis. The findings represent, to the authors' knowledge, the first known case of a patient with coexistent functional cortisol-secreting macronodular adrenal tumor resulting in Cushing syndrome and immune-mediated adrenalitis resulting in Addison disease.

    Spontaneous adrenal hemorrhage (SAH) is a serious medical condition associated with variable clinical presentation depending on the extent of the hemorrhage. Pregnancy-induced adrenal hemorrhage is poorly understood. A low cortisol level in the peripartum period with radiological findings is sufficient to establish the diagnosis. Prompt hormone replacement and supportive care to ensure good clinical outcomes is crucial. Due to the potentially life-threatening complications, physicians should have a high suspicion for adrenal hemorrhage when they evaluate patients with hypotension, fatigue, and abdominal pain during the peripartum 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 < 200 μg/g) may benefit from a trial of pancreatic enzyme replacement therapy (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

    Kisspeptins are neuropeptides which activate the hypothalamo-pituitary gonadal axis and are considered to play important physiological roles in the reproduction. Kisspeptins have also been reported to stimulate the aldosterone secretion from the adrenal cortex. However, the expression of kisspeptins in human adrenal glands and adrenal tumors has not been clarified yet. We, therefore, studied the presence of kisspeptin-like immunoreactivity (LI) in human adrenal glands and adrenal tumors (adrenocortical adenomas, adrenocortical carcinomas, and pheochromocytomas) by radioimmunoassay and immunocytochemistry. Kisspeptin-LI was detected in all the tissues examined; normal portions of adrenal glands (3.0 +/- 2.3 pmol/g wet weight, n = 21, mean +/- SD), aldosterone-producing adenomas (4.6 +/- 3.3 pmol/g wet weight, n = 10), cortisol-producing adenomas (2.7 +/- 1.4 pmol/g wet weight, n = 14), adrenocortical carcinomas (1.7 +/- 0.2 pmol/g wet weight, n = 4), and pheochromocytomas (1.8 +/- 0.8 pmol/g wet weight, n = 6). There was no significant difference in kisspeptin-LI levels among them. Immunocytochemistry showed positive kisspeptin-immunostaining in normal adrenal glands, with stronger immunostaining found in the medulla. Furthermore, positive kisspeptin-immunostaining was found in all types of adrenal tumors examined; adrenocortical adenomas, adrenocortical carcinomas, and pheochromocytomas. The intensity of kisspeptin-immunostaining in these adrenal tumors was, however, not so strong as that in normal adrenal medulla. The present study has shown for the first time the presence of kisspeptin-LI in adrenal glands and adrenal tumors.

    Summary A functional lesion in corticotrophin (ACTH)-independent Cushing’s syndrome is difficult to distinguish from lesions of bilateral adrenal masses. Methods for distinguishing these lesions include adrenal venous sampling and 131I-6β-iodomethyl-19-norcholesterol (131I-NP-59) scintigraphy. We present a case of a 29-year-old Han Chinese female patient with a history of hypercholesterolaemia and polycystic ovary syndrome. She presented with a 6month history of an 8kg body weight gain and gradual rounding of the face. Serial examinations revealed loss of circadian rhythm of cortisol, elevated urinary free-cortisol level and undetectable ACTH level (<5pg/mL). No suppression was observed in both the low- and high-dose dexamethasone suppression tests. Adrenal computed tomography revealed bilateral adrenal masses. Adrenal venous sampling was performed, and the right-to-left lateralisation ratio was 14.29. The finding from adrenal scintigraphy with NP-59 was consistent with right adrenal adenoma. The patient underwent laparoscopic right adrenalectomy, and the pathology report showed adrenocortical adenoma. Her postoperative cortisol level was 3.2μg/dL, and her Cushingoid appearance improved. In sum, both adrenal venous sampling and 131I-NP-59 scintigraphy are good diagnostic methods for Cushing’s syndrome presenting with bilateral adrenal masses. Learning points The clinical presentation of Cushing’ syndrome includes symptoms and signs of fat redistribution and protein-wasting features. The diagnosis of patients with ACTH-independent Cushing’s syndrome with bilateral adrenal masses is challenging for localisation of the lesion. Both adrenal venous sampling and 131I-NP-59 scintigraphy are good methods to use in these patients with Cushing’s syndrome presenting with bilateral adrenal masses. PMID:27252858

    The clinical presentation of adrenal hemorrhage varies, depending on the extent of hemorrhage as well as the amount of adrenal cortex involved by the hemorrhage. We report here a case of neonatal adrenal hemorrhage revealed by late onset of neonatal jaundice. This adrenal hemorrhage most probably resulted from shoulder dystocia. The aim of this work was to focus on the fact that jaundice can be caused by adrenal hemorrhage and to emphasize the crucial importance of abdominal ultrasound in cases of persistent jaundice.

    Injection of botulinum toxin (BT) and pneumatic dilatation are available methods in nonsurgical treatment of achalasia. Authors anticipate beneficial effect of prior BT injection on the success of pneumatic dilatation and duration of its effect. There are no long-term data available to assess efficacy of combined treatment. From 1998 to 2007, 51 consecutive patients (20 men and 31 women, age 24-83) with achalasia were included and prospectively followed up. Each patient received injection of 200 IU of BT into the lower esophageal sphincter (LES) during endoscopy and 8 days later pneumatic dilatation (PD) under X-ray control was performed. The follow-up was established every 3 months first year and then annually. The efficacy was evaluated by a questionnaire concerning patient's symptoms and manometry. Results were compared with 40 historical controls (16 men and 24 women, age 26-80) treated by PD alone using the same method and follow-up. Fifty-one patients underwent combined treatment. Four patients failed in follow-up and were not included for analysis. The mean duration of follow-up was 48 months with range 12-96 months. Thirty-four of forty-seven (72%) patients were satisfied with results with none or very rare and mild troubles at the time of the last visit. Forty-one patients were followed up more than 2 years. Effect of therapy lasted in 75% (31/41) of them. In 17 patients, more than 5 years after treatment, effect lasted in 12 (70%). Mean tonus of LES before therapy was 29 mm Hg (10-80), 3 months after therapy decreased to 14 mmHg (5-26). The cumulative 5 years remission rate (+/-95% CI) in combined treated patients 69% +/- 8% was higher than in controls 50% +/- 9%; however it, was not statistically significant (P= 0.07). In control group 1, case of perforation (2.5%) occurred. Eight patients (17%) with relapse of dysphagia were referred to laparoscopic Heller myotomy with no surgical complication.

    The present study examined the presence of advanced glycosylation end products (AGEs) in lipofuscin present in the brain and adrenal gland of aging rats by immunohistochemistry using antibodies raised against AGEs. Lipofuscin identified as yellow to brown granules emitting bright yellow to orange autofluorescence with ultraviolet light were detected in cortical neurons, cerebellar Purkinje cells, and adrenal cells in the inner part of the zona reticularis. However, none of the antibodies visualized lipofuscin in these areas. The outer part of the zona reticularis contained yellow granules emitting a faint orange autofluorescence. These granules were immunostained by an antibody that reacted with AGEs structures unrelated to the carboxymethyllysine moiety. Newly formed adrenal cortical cells are thought to migrate from the outer layer to the inner layer of the zona reticularis. Therefore, our results suggest that glycosylation-related processes are involved in lipofuscinogenesis, at least in its early stage, in the adrenal zona reticularis.

    Although laparoscopic adrenalectomy has remained the standard of care for the treatment for adrenal tumors, percutaneous image-guided ablation therapy, such as chemical ablation, radiofrequency ablation, cryoablation, and microwave ablation, has been shown to be clinically useful in many nonsurgical candidates. Ablation therapy has been used to treat both functioning adenomas and malignant tumors, including primary adrenal carcinoma and metastasis. For patients with functioning adenomas, biochemical and symptomatic improvement is achieved in 96 to 100% after ablation; for patients with malignant adrenal neoplasms, however, the survival benefit from ablation therapy remains unclear, though good initial results have been reported. This article outlines the current role of ablation therapy for adrenal lesions, as well as identifying some of the technical considerations for this procedure.

    Background Association between esophageal achalasia/ gastroesophageal reflux disease (GERD) and cholelithiasis is not clear. Epidemiological data are controversial due to different methodologies applied, the regional differences and the number of patients involved. Results of concomitant cholecistectomy associated to surgical treatment of both diseases regarding safety is poorly understood. Aim To analyze the prevalence of cholelithiasis in patients with esophageal achalasia and gastroesophageal reflux submitted to cardiomyotomy or fundoplication. Also, to evaluate the safety of concomitant cholecistectomy. Methods Retrospective analysis of 1410 patients operated from 2000 to 2013. They were divided into two groups: patients with GERD submitted to laparocopic hiatoplasty plus Nissen fundoplication and patients with esophageal achalasia to laparoscopic cardiomyotomy plus partial fundoplication. It was collected epidemiological data, specific diagnosis and subgroups, the presence or absence of gallstones, surgical procedure, operative and clinical complications and mortality. All groups/subgroups were compared. Results From 1,229 patients with GERD or esophageal achalasia, submitted to laparoscopic cardiomyotomy or fundoplication, 138 (11.43%) had cholelitiasis, occurring more in females (2.38:1) with mean age of 50,27 years old. In 604 patients with GERD, 79 (13,08%) had cholelitiasis. Lower prevalence occurred in Barrett's esophagus patients 7/105 (6.67%) (p=0.037). In 625 with esophageal achalasia, 59 (9.44%) had cholelitiasis, with no difference between chagasic and idiopathic forms (p=0.677). Complications of patients with or without cholecystectomy were similar in fundoplication and cardiomyotomy (p=0.78 and p=1.00).There was no mortality or complications related to cholecystectomy in this series. Conclusions Prevalence of cholelithiasis was higher in patients submitted to fundoplication (GERD). Patients with chagasic or idiopatic forms of achalasia had the

    Inhaled corticosteroids (ICS) are drugs of choice for persistent asthma. Less than 500 µg/d of fluticasone are believed to be safe. We found 92 cases of adrenal suppression in PubMed; among these cases there were 13 children who took 500 µg/d or less of fluticasone. Adrenal insufficiency was diagnosed in a 7-year-old boy on 460 µg ICS for 16 months, with a diagnosis of chronic persistent asthma. A random cortisol was nondetectable as was an early morning cortisol. ICS have greatly improved the day-to-day lives of children with chronic persistent asthma. Parents of children younger than 12 years, who use at least 400 µg of inhaled fluticasone (or bioequivalent), must be given oral and written instructions about warning symptoms of hypocortisolism. Major stress such as surgery, gastrointestinal, bronchopulmonary, or other systemic infections, and heat stress may mandate a written plan of action for use by hospital physicians.

    The synthesis of adrenal cholesterol, its esterification and the synthesis of the glucocorticosteroid hormones were studied in vitro on human adrenal tissue. It was found that the synthesis of adrenal cholesterol may normally be small in the zona “fasciculata,” particularly when compared with the synthesis of the glucocorticosteroid hormones, that it is several times higher in the zona “reticularis” where esterified cholesterol is less abundant, and that under ACTH stimulation it increases strikingly and proportionally to the degree of esterified adrenal cholesterol depletion. On the other hand, the relative rate of esterification as well as the concentration of free adrenal cholesterol are remarkably stable: they do not differ according to the adrenal zonation and are unaffected by ACTH. Furthermore, from a qualitative point of view, the relative proportions of Δ1 and Δ2 cholesteryl esters formed in situ are similar to those anticipated from their relative concentrations, suggesting that the characteristic fatty acid distribution of the adrenal cholesteryl esters results from an in situ esterification rather than from a selective uptake of the plasma cholesteryl esters. Besides, the in vitro esterification reveals a propensity to the formation of the most unsaturated cholesteryl esters. Regarding hydrocortisone and corticosterone, their synthesis tends to be more elevated in the zona “fasciculata.” Despite its higher cholesterol concentration the zona “fasciculata” should not therefore be viewed as a quiescent functional complement to the zona “reticularis” and the cortical distribution of glucocorticosteroid hormone synthesis is quite distinct from that of adrenal cholesterol synthesis.

    Extrinsic compression of the left atrium by the esophagus, the stomach, or both is an uncommon but important cause of hemodynamic compromise. Achalasia is a motility disorder characterized by impaired relaxation of the lower esophageal sphincter and dilatation of the distal two thirds of the esophagus. Echocardiographic imaging after oral ingestion of liquid containing carbon dioxide allowed for differentiation between a compressive vascular structure and the esophagus. We report a rare case of esophageal achalasia compressing the left atrium diagnosed by echocardiography using a liquid containing carbon dioxide in a 21-year-old woman with Turner syndrome.

    Functioning black adrenal adenoma (BAA) rarely causes preclinical Cushing's syndrome (CS). In the present case, a 46-year-old Japanese Peruvian woman presented with left flank pain and hypertension. Abdominal computed tomography showed that she had a 15-mm in diameter, round, left adrenal adenoma. She had no physical features of CS, such as moon face, buffalo hump, truncal obesity, or purple striae. Endocrinological examination showed that the plasma adrenocorticotropic hormone (ACTH) level was below the detectable level, despite a serum cortisol level within the normal range. A normal cortisol circadian rhythm was not present. Dexamethasone (1 mg and 8 mg) suppression testing did not decrease serum cortisol levels to the reference levels. These findings were compatible with preclinical CS. The left adrenal adenoma was laparoscopically removed. Examination of the surgical specimen revealed unilateral double adrenal adenomas of the left adrenal gland, one of which was a BAA. The BAA measured 20 × 11 × 10 mm. Microscopically, the BAA showed proliferation of compact cells containing numerous brown-pigmented granules. There were also foci of myelolipomatous degenerative changes in the tumor. The compact cell zones remained in the adrenal cortex adjacent to the BAA showed atrophic change. These findings indicated that BAA appeared to have caused preclinical CS in this patient.

    The effects of hypothyroidism on the functional integrity of the hypothalamic-pituitary-adrenal (HPA) axis were investigated in adult male rats. HPA axis function was examined in vivo in sham-thyroidectomized male Sprague-Dawley rats or in thyroidectomized rats for 7 (short-term hypothyroidism) or 60 (long-term hypothyroidism) days. Peripheral ACTH and corticosterone responses to insulin-induced hypoglycemia and interleukin (IL)-1α stimulation were used to indirectly assess the hypothalamic CRH neuron. Hypothyroidism resulted in exaggerated ACTH responses to both hypoglycemic stress and IL-1α administration. The adrenal cortex of hypothyroid animals showed a significant reduction in adrenal reserves, as assessed by its response to low-dose ACTH, following suppression of the HPA axis with dexamethasone. Hypothyroid rats were also associated with significant decreases in cerebrospinal fluid corticosterone concentrations and decreased adrenal weights. The findings suggest that experimentally induced hypothyroidism is associated with a mild, yet significant, adrenal insufficiency, which involves abnormalities in all components of the HPA axis.

    Patients with liver cirrhosis may present impaired sleep-wake and circadian rhythms, relative adrenal insufficiency and altered hypothalamus-pituitary-adrenal gland (HPA) axis. The underlying mechanisms remain unclear. Circadian rhythms are modulated by corticosteroids which secretion is regulated by HPA axis. Hyperammonemia alters circadian rhythms of activity and corticosterone in rats. The aims were: (1) assessing whether corticosterone alterations are responsible for altered circadian rhythm in hyperammonemia: (2) to shed light on the mechanism by which corticosterone circadian rhythm is altered in hyperammonemia. The effects of daily corticosterone injection at ZT10 on circadian rhythms of activity, plasma corticosterone, adreno-corticotropic hormone (ACTH) and hypothalamic corticotropic releasing hormone (CRH) were assessed in control and hyperammonemic rats. ACTH-induced corticosterone release was analyzed in cultured adrenal cells. Corticosterone injection restores the corticosterone peak in hyperammonemic rats and their activity and circadian rhythm. Plasma ACTH and CRH in hypothalamus are increased in hyperammonemic rats. Corticosterone injection normalizes ACTH. Chronic hyperammonemia impairs adrenal function, reduces corticosterone content and ACTH-induced corticosterone release in adrenals, leading to reduced feedback modulation of HPA axis by corticosterone which contributes to impair circadian rhythms of activity. Impaired circadian rhythms and motor activity may be corrected in hyperammonemia and hepatic encephalopathy by corticosterone treatment.

    In congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency, affected girls are born with ambiguous genitalia due to increased secretion of androgens in utero by the defective adrenal gland. Even though it is generally accepted that there are differences between male and female brain development, determining factors have been difficult to identify. Girls with CAH have frequently been studied to evaluate the impact of prenatal androgen exposure on psychological, psychosocial, and psychosexual development, and impairments in various areas have been identified. However, there is no comprehensive study available regarding the outcome of this chronic disorder in adult life. We studied the quality of life in women with CAH, with particular emphasis on how they cope with genital malformations, genital operations, and chronic disease as well as lifelong medication. The patients filled out questionnaires covering their physical state, psychological well-being, social relationships, and functional capacity, as well as questionnaires on psychosexual identification and psychosocial integration. The results were evaluated using a computerized statistical program for social studies. Out of a total of 94 patients above 18 years of age, 45 agreed to participate and were compared to 46 healthy, age-matched controls. Age at diagnosis was 2. 31 +/- 1.55 years and 38% suffered from the simple-virilizing, 45% from the salt-wasting, and 17.0% from the late-onset form of CAH. About one-third of patients had Prader stage 3 or 4 genital virilization. While the overall quality of life did not differ significantly, CAH patients were more often single (47.8% vs. 66.7%) and fewer of them had children (22.2% vs. 38.6%) compared to controls. Significant impairments were found in regard to body image and attitudes toward sexuality, but there was no increased homosexual preference. The women were successful in adjusting to illness and receiving social support. It is speculated that

    The adrenal glands are located superior to the kidneys and play an important role in the endocrine system. Each adrenal gland contains an outer cortex, responsible mainly for the secretion of androgens and corticosteroids, and an inner medulla, which secretes epinephrine and norepinephrine. Here, we review the anatomy of the adrenal glands and explain the current imaging modalities that are most useful for the assessment of the various conditions--both benign and malignant--that can affect these glands. As adrenal lesions are often identified incidentally on cross-sectional imaging performed for other reasons, the management of such adrenal 'incidentalomas' is also discussed. In many cases, adrenal lesions have distinctive imaging features that allow for a full characterization with noninvasive techniques. In some cases, invasive studies such as adrenal vein sampling or adrenal biopsy become necessary. This review should give the reader a wide overview of how various imaging techniques can be useful in the assessment of adrenal pathology.

    The most important novel findings presented on oesophageal disease in DDW 2015 were the following: 1) GERD: a) hypervigilance seems to be a key pathogenic factor in reflux symptoms refractory to PPI; b) post-reflux swallowing-induced peristaltic waves could be an excellent diagnostic criterion for GERD; c) laryngeal pH-metry is not useful in the diagnosis of extra-oesophageal symptoms; d) the recommendation of weight loss adequately recorded in the clinical reports of patients with GERD and obesity or overweight is an excellent quality indicator and is associated with better outcomes. 2) Barrett's oesophagus: a) persistent low-grade dysplasia in more than one endoscopy and a diagnosis of "indefinite for dysplasia" are associated with a high risk of neoplastic progression; b) narrow-band imaging allows areas of dysplasia on Barrett's oesophagus to be identified with high sensitivity and specificity; c) initial endoscopy fails to identify a high percentage of advanced neoplasms in Barrett's oesophagus. Early re-endoscopy should be considered; d) endoscopists specialized in Barret's oesophagus obtain a much higher yield in the diagnosis of advanced lesions. Patients at high risk-men, older patients, smokers and those with long-segment Barrett's oesophagus-could benefit from follow-up in a referral center. 3) Achalasia: POEM seems safe and effective, independently from patient characteristics (age, comorbidity) and the technical variations used. 4) Eosinophilic esophagitis: topical budesonide and exclusion diets are reasonably effective in PPI non-responders.

    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.

    We aimed to assess the short-term outcomes of per-oral endoscopic myotomy (POEM) compared with laparoscopic Heller myotomy (LHM) for achalasia through a meta-analysis of nonrandomized comparative studies.We searched PubMed, Embase, Medline, Cochrane Library, and Google Scholar for studies that compared POEM and LHM for achalasia and were published between January 1, 2008 and December 31, 2014. The Methodological Index for Nonrandomized Studies (MINORS) was used to evaluate the quality of the studies. Random- and fixed-effects meta-analytical models were used, and between-study heterogeneity was assessed.Four nonrandomized comparative studies that included 317 patients (125 in the POEM group and 192 in the LHM group) met our research criteria and were assessed. There were no differences between the POEM and LHM groups in terms of sex, preoperative Eckhart score, length of myotomy, operation time, length of hospital stay, and complications. The patients in the POEM group were older than those in the LHM group (MD =2.81, 95% CI 0.27-5.35; P = 0.03) with high between-study homogeneity (χ = 1.96, df = 2, I = 0%; P = 0.38). The patients in the POEM group had a lower Eckardt score after surgery compared with those in the LHM group (MD = -0.30, 95% CI -0.42 to -0.18; P < 0.001) with high between-study homogeneity (χ = 0.00, df = 1, I = 0%; P = 1.00).The efficacy and safety of POEM appear to be comparable to those of LHM. Multicenter and randomized trials with larger sample size are needed to further compare the efficacy and safety of POEM and LHM for the treatment of achalasia.

    Adrenocortical carcinoma (ACC) is a rare and aggressive malignancy. Sarcomatoid adrenal carcinoma is even more aggressive type of ACC. Bilateral malignant adrenal tumors are extremely rare except for those that represent metastasis from an extra-adrenal organ. Here we report a 53-year-old woman who presented with abdominal pain and weight loss. Abdominal computed tomography revealed bilateral adrenal masses and a mass in her liver. Surgical specimens showed pleomorphic tumor cells with epithelial and spindle cell morphology and immunohistochemical staining was compatible with sarcomatoid carcinoma. Sarcomatoid adrenal carcinoma should be kept in mind during the management of bilateral adrenal masses. PMID:28097033

    : Adrenal diseases--including disorders such as Cushing's syndrome, Addison's disease, pheochromocytoma, primary hyperaldosteronism and congenital adrenal hyperplasia--are relatively rare in pregnancy, but a timely diagnosis and proper treatment are critical because these disorders can cause maternal and fetal morbidity and mortality. Making the diagnosis of adrenal disorders in pregnancy is challenging as symptoms associated with pregnancy are also seen in adrenal diseases. In addition, pregnancy is marked by several endocrine changes, including activation of the renin-angiotensin-aldosterone system and the hypothalamic-pituitary-adrenal axis. The aim of this article was to review the pathophysiology, clinical manifestation, diagnosis and management of various adrenal disorders during pregnancy.

    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.

    Environmental contamination by petroleum hydrocarbons from anthropogenic sources can be a cause of stress for free-ranging wildlife. The response of wildlife to chemical contaminants requires that the hypothalamic-pituitary-adrenal (HPA) axis be precisely regulated to allow for proper glucocorticoid-mediated adaptive responses. Chronic oral exposure to low concentrations of bunker C fuel oil causes the development of adrenal hypertrophy in male ranch mink (Mustela vison) without increasing serum or fecal glucocorticoid concentrations. This hypertrophy is an adaptive response to fuel oil-induced adrenal insufficiency. To determine if the same phenomenon occurs in female mink or male mink exposed to artificially weathered fuel oil, female mink were fed 0 ppm (mineral oil) or 420 ppm fuel oil and male mink were exposed to 0 ppm, 420 ppm fuel oil, or 480 ppm artificially weathered fuel oil in the diet for 60-62 days. At the end of the exposure, serum glucocorticoid concentrations were assayed along with body and organ weight measurements. Fecal glucocorticoid concentrations were assayed at time points throughout the exposure. Male mink fed fuel oil or weathered fuel oil and female mink fed fuel oil had adrenal enlargement without any significant increases in the serum or fecal concentration of glucocorticoids, which is consistent with fuel oil-induced adrenal insufficiency. To address the physiological consequences of adrenal insufficiency, fuel oil-exposed male mink were administered an adrenocorticotropic hormone (ACTH) stimulation test. Fuel oil-exposed animals had a smaller incremental increase in serum glucocorticoid concentration after ACTH challenge compared to control animals. Our findings provide further evidence that the HPA axis of fuel oil-exposed animals is compromised and, therefore, not able to respond appropriately to the diverse stressors found in the environment.

    The adrenal is the most common toxicological target organ in the endocrine system in vivo and yet it is neglected in regulatory endocrine disruption screening and testing. There has been a recent marked increase in interest in adrenal toxicity, but there are no standardised approaches for assessment. Consequently, a strategy is proposed to evaluate adrenocortical toxicity. Human adrenal conditions are reviewed and adrenocortical suppression, known to have been iatrogenically induced leading to Addisonian crisis and death, is identified as the toxicological hazard of most concern. The consequences of inhibition of key steroidogenic enzymes and the possible toxicological modulation of other adrenal conditions are also highlighted. The proposed strategy involves an in vivo rodent adrenal competency test based on ACTH challenge to specifically examine adrenocortical suppression. The H295R human adrenocortical carcinoma cell line is also proposed to identify molecular targets, and is useful for measuring steroids, enzymes or gene expression. Hypothalamo-pituitary-adrenal endocrinology relevant to rodent and human toxicology is reviewed (with an emphasis on multi-endocrine axis effects on the adrenal and also how the adrenal affects a variety of other hormones) and the endocrinology of the H295R cell line is also described. Chemicals known to induce adrenocortical toxicity are reviewed and over 60 examples of compounds and their confirmed steroidogenic targets are presented, with much of this work published very recently using H295R cell systems. In proposing a strategy for adrenocortical toxicity assessment, the outlined techniques will provide hazard assessment data but it will be regulatory agencies that must consider the significance of such data in risk extrapolation models. The cases of etomindate and aminoglutethimide induced adrenal suppression are clearly documented examples of iatrogenic adrenal toxicity in humans. Environmentally, sentinel species, such as

    Adrenal imaging using radiopharmaceuticals is a functional test that can contribute significantly to surgical management and follow-up of patients with either benign or malignant conditions of the adrenal cortex and medulla. Imaging of the cortex is achieved by iodine-131-labeled iodomethyl nor-cholesterol (NP-59), while adrenal medulla imaging can be successfully accomplished by 131I-metaiodobenzylguanidine (MIBG), which localizes in the adrenergic nerve terminal with norepinephrine. Both tests carry high sensitivity and specificity for functional tumors and hyperplasia, and often better than CT scanning. This article reviews the current status and clinical utility of nuclear imaging of the adrenal cortex in congenital hyperplasia, low renin hypertension and aldosteronism, and Cushing's syndrome. Adrenal medulla imaging is reviewed in light of our experience at the University of Texas M.D. Anderson Cancer Center in pheochromocytoma, neuroblastoma, and other neuroectodermal tumors. Investigation of {sup 131}I-MIBG therapy of metastatic tumors of neuroectodermal origin potentially offers a means of at least controlling symptoms of hormonal secretion in these patients. 40 references.

    Endogenous glucocorticoid-induced thymic involution is generally considered to be an important finding for determining child abuse. The present study investigated the weight of the thymus and the adrenal glands in elder abuse cases to identify a potential marker for elder abuse. There was no significant difference in the thymus and the adrenal weight between elder abuse and control cases. However, the elder abuse cases in which the duration of abuse was less than 3 months showed a significant increase in the adrenal weight in comparison to control cases. In such cases, histopathological findings showed a loss of intracellular light granules from the zona fasciculata, which might indicate a loss of cholesterol due to the overproduction of glucocorticoid. These results might imply that the elderly, who were maltreated for less than 3 months, were in the early phase of a long-term stress state during which stress-induced overproduction of glucocorticoid was observed in adrenal glands as indicated by Selye. Our results suggest that an increase in adrenal weight may be a potential marker for elder abuse of relatively short periods, especially less than a few months.

    The purpose of this study is to assess the effects of hypothyroidism on the hypothalamic-pituitary-adrenal (HPA) axis; the functional integrity of each component of the HPA axis was examined in short-term and long-term hypothyroidism. Neuropeptide synthesis, release, and content were evaluated in vitro both in the hypothalamus and anterior pituitary, and corticosterone release was assessed in primary adrenal cell cultures at 7 (short-term) and 60 days (long-term hypothyroidism) after thyroidectomy in male rats. Hypothyroid rats showed adrenal insufficiency in several parameters, which were associated with the duration of hypothyroidism. Cerebrospinal (CSF) ACTH was decreased in all hypothyroid animals, while CSF corticosterone levels were significantly decreased only in long-term hypothyroidism. Long-term hypothyroid animals showed decreased corticotropin-releasing hormone (CRH) mRNA expression in the hypothalamic paraventricular nucleus under both basal and stress conditions, decreased CRH release from hypothalamic organ cultures after KCL and arginine vasopressin stimulation, as well as an increased number of anterior pituitary CRH receptors. In contrast, short-term hypothyroid rats showed changes in anterior pituitary function with an increased responsiveness to CRH that was associated with an increase in CRH receptors. Although both short- and long-term hypothyroidism was associated with significant decreases in adrenal weights, only long-term hypothyroid rats showed changes in adrenal function with a significant decrease of ACTH-induced corticosterone release from cultured adrenal cells. The data suggest that long-term hypothyroidism is associated with adrenal insufficiency with abnormalities in all three components of the HPA axis. Short-term hypothyroidism, on the other hand, is associated with increased pituitary corticotroph responsiveness to CRH.

    With the steep increase in the use of cross-sectional imaging in recent years, the incidentally detected adrenal lesion, or "incidentaloma", has become an increasingly common diagnostic problem for the radiologist, and a need for an approach to classifying these lesions as benign, malignant or indeterminate with imaging has spurred an explosion of research. 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.

    Image-guided biopsy is a safe and well-established technique that is familiar to most interventional radiologists (IRs). Improvements in image-guidance, biopsy tools and biopsy techniques now routinely allow for safe biopsy of renal and adrenal lesions which traditionally were considered difficult to reach or technically challenging. Image-guided biopsy is used to establish the definitive tissue diagnosis in adrenal mass lesions that can not be fully characterized with imaging or laboratory tests alone. It is also used to establish definitive diagnosis in some cases of renal parenchymal disease and has an expanding role in diagnosis and characterization of renal masses prior to treatment. Although basic principles and techniques for image-guided needle biopsy are similar regardless of organ, this paper will highlight some technical considerations, indications and complications which are unique to the adrenal gland and kidney because of their anatomic location and physiologic features.

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. PMID:25741090

  13. Adrenal Hemorrhage in Neonates: Unusual Presentation.

    Adrenal hemorrhage (AH) is a relatively uncommon condition in newborns. It may be asymptomatic or may present with flank abdominal mass, anemia, jaundice, or rarely as scrotal bruising or hematoma. We report two cases of AH in neonates; the first presented with scrotal hematoma and the second with adrenal mass associated with hypertension and oliguria, primarily secondary to coincidental renal vein thrombosis. Diagnosis was confirmed by abdominal ultrasound. Patients were managed conservatively with clinical observation and by following hemoglobin and bilirubin levels closely. Both infants were discharged without surgical intervention after several days in the hospital. Clinicians should consider AH when a newborn presents with scrotal bruising or hematoma, unexplained anemia, unexplained jaundice, or flank abdominal mass. Timely ultrasonographic evaluation of both adrenal glands and testes in neonates with scrotal hematoma may spare infants from unnecessary surgical intervention because scrotal hematoma often raises the suspicion of testicular torsion.

    Background and Objectives: Laparoscopy has acquired an unquestionable position in surgical practice as a diagnostic and operative tool. Recently, the laparoscopic approach has become a valuable option for adrenalectomy. This paper reports, in detail, our experience of laparoscopic adrenalectomy performed for adrenal tumors. Methods: We performed 12 laparoscopic adrenalectomies from October 29, 1997 to October 31, 1998. The technique of laparoscopic adrenalectomy is described thoroughly in all relevant details for either left or right-sided adrenal lesions. Results: The presented technique of laparoscopic adrenalectomy in all 12 cases provided good and relatively simple exposure of the immediate operative area. All relevant vascular elements were safely controlled, adrenal tumors could be successfully removed, and adequate hemostasis was achieved. No intraoperative or postoperative complications were observed. Conclusions: Laparoscopic adrenalectomy is a safe alternative to open surgery and is preferred for most patients because of shorter postoperative hospital stay and less postoperative discomfort.

    The CT appearance of the adrenal glands was investigated in 30 patients with congenital renal anomalies. The ipsilateral adrenal was clearly identified in 83% of these patients; in all of them, the adrenal was a paraspinal disk-shaped organ, which appeared linear on CT. Conversely, the adrenals retained their normal shape in a control group of 20 patients with acquired renal atrophy or prior simple nephrectomy.

    The adrenal hemorrhage is a relatively rare event in newborns but must be considered in the presence of a persistent unexplained jaundice, especially in presence of predisposing factors. Serial ultrasonography is the modality of choice for initial diagnosis and follow-up of neonatal adrenal hemorrhage. We report two cases of neonatal adrenal hemorrhage presenting with persistent jaundice. The causes of the neonatal adrenal hemorrhages were a difficult vaginal delivery in macrosomic infant and a neonatal infection.

    Chromoendoscopy with Lugol's staining remains the gold standard technique for detecting superficial SCC. An alternative technique, such as narrow-band imaging (NBI), for "optical staining" would be desirable, since NBI is a simpler technique and has no known complications. In this study, we compare NBI without magnification and chromoendoscopy with Lugol's staining for detecting high-grade dysplasia and intramucosal esophageal squamous cell carcinoma (SCC) in patients with achalasia. This was a prospective observational study of 43 patients with achalasia referred to the Gastrointestinal Endoscopy Unit of the Hospital of Clinics, São Paulo, University Medical School, Brazil, from October 2006 to February 2007. Conventional examinations with white light, NBI, and Lugol staining were consecutively performed, and the suspected lesions were mapped, recorded, and sent for biopsy. The results of the three methods were compared regarding sensitivity, specificity, accuracy, positive predictive value, negative predictive value, positive likelihood value, and negative likelihood value. Of the 43 patients, one was diagnosed with esophageal squamous cell carcinoma, and it was detected by all of the methods. NBI technology without magnification has high sensitivity and negative predictive value for detecting superficial esophageal squamous cell carcinoma, and it has comparable results with those obtained with Lugol's staining.

    Background Polymorphisms of genes involved in the regulation of the immune response are risk factors for achalasia, but their contribution to disease pathogenesis is unknown. Nitric oxide is involved both in immune function and inhibitory neurotransmission. Objective The objective of this article is to assess the association and the functional relevance of the CCTTT-inducible nitric oxide synthase (NOS2) gene promoter polymorphism in achalasia. Methods Genomic DNA was isolated from 181 achalasia patients and 220 controls. Genotyping of the (CCTTT)n repeats was performed by PCR and capillary electrophoresis, and data analyzed by considering the frequency of the different alleles. HT29 cells were transfected with iNOS luciferase promoter-reporter plasmids containing different (CCTTT)n. Results The alleles’ distribution ranged from 7 to 18, with a peak frequency at 12 repeats. Analysis of the allele frequencies revealed that individuals carrying 10 and 13 CCTTT repeats were respectively less and more frequent in achalasia (OR 0.5, 95% CI 0.3–0.5 and OR 1.6, 95% CI 1–2.4, all p < 0.05). Long repeats were also significantly associated with an earlier onset of the disease (OR 1.69, 95% CI 1.13–2.53, p = 0.01). Transfection experiments revealed a similar allele-specific iNOS transcriptional activity. Conclusion The functional polymorphism (CCTTT) of NOS2 promoter is associated with achalasia, likely by an allele-specific modulation of nitric oxide production. PMID:28344787

    Congenital adrenal hyperplasia describes a group of inherited autosomal recessive disorders characterized by an enzymatic defect in cortisol biosynthesis, compensatory increases in corticotropin secretion, and adrenocortical hyperplasia. 21-Hydroxylase deficiency is responsible for more than 95% of cases and is one of the most common known autosomal recessive disorders. The classic or severe type presents in the newborn period or early childhood with virilization and adrenal insufficiency, with or without salt loss; the mild or nonclassic form presents in late childhood or early adulthood with mild hyperandrogenism and is an important cause of masculinization and infertility in women. This wide range of phenotypic expression is mostly explained by genetic variation, although genotype-phenotype discrepancies have been described. Reproductive, metabolic, and other comorbid conditions, including risk for tumors, are currently under investigation in both forms of the disease. A high proportion of patients with adrenal incidentalomas may be homozygous or heterozygous for 21-hydroxylase deficiency. Women with congenital adrenal hyperplasia often develop the polycystic ovary syndrome. Ectopic adrenal rest tissue is often found in the testes of men with congenital adrenal hyperplasia; characteristic clinical and radiologic findings help differentiate this tissue from other tumors. Levels of corticotropin-releasing hormone are elevated in patients with depression and anxiety and are expected to be elevated in patients with congenital adrenal hyperplasia; it is unknown whether patients with 21-hydroxylase deficiency have an increased incidence of these psychiatric disorders. Abnormalities in both the structure and function of the adrenal medulla have been shown in patients with classic congenital adrenal hyperplasia, and the degree of adrenomedullary impairment may be a biomarker of disease severity. The 21-hydroxylase-deficient mouse has provided a useful model with which

    Steroid 21 hydroxylase deficiency is the most common form of congenital adrenal hyperplasia (CAH). The severity of this disorder depends on the extent of impaired enzymatic activity, which is caused by various mutations of the 21 hydroxylase gene. This article reviews adrenal steroidogenesis and the pathophysiology of 21 hydroxylase deficiency. The three forms of CAH are then discussed in terms of clinical presentation, diagnosis and treatment, and genetic basis. Prenatal diagnosis and treatment are also reviewed. The goal of therapy is to correct the deficiency in cortisol secretion and suppress androgen overproduction. Glucocorticoid replacement has been the mainstay of treatment for CAH, but new treatment strategies continue to be developed and studied.

    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.

    Pheochromocytomas are usually solid tumours. But it can present as cystic lesions in the adrenal gland. Cystic lesions in adrenal gland with hypertension needs attention to rule out pheochromocytoma. If ignored, it may lead to hypertensive emergency, multisystem crisis and death. Early diagnosis with biochemistry, Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) of abdomen, proper functional imaging like Meta Iodo Benzyl Guanidine (MIBG) scan is essential. Proper preoperative preparation is important to prevent hypertensive crisis during and after surgery. We are reporting a case of cystic pheochromocytoma in a young male. PMID:28050427

    It has been known for over 70 years that adrenal catecholamine secretion can be modulated or elicited by noncholinergic neurotransmitters and hormones. However, our understanding of the cellular mechanisms by which these agents produce their effects and the physiological conditions under which they act are not well characterised. Here we briefly review the mechanisms by which one such agent (the neuropeptide substance P) modulates the cholinergic secretory response of adrenal chromaffin cells, and another agent (angiotensin II) elicits catecholamine secretion independently of the cholinergic innervation.

    The first part of the study aimed to describe prospectively the ultrasonographic features of the adrenal glands in 94 healthy cats and 51 chronically sick cats. It confirmed the feasibility of ultrasonography of adrenal glands in healthy and chronically sick cats, which were not statistically different. The typical hypoechoic appearance of the gland surrounded by hyperechoic fat made it recognisable. A sagittal plane of the gland, not in line with the aorta, may be necessary to obtain the largest adrenal measurements. The reference intervals of adrenal measurements were inferred from the values obtained in the healthy and chronically sick cats (mean ± 0.96 SD): adrenal length was 8.9-12.5 mm; cranial height was 3.0-4.8 mm; caudal height was 3.0-4.5 mm. The second part of the study consisted of a retrospective analysis of the ultrasonographic examination of the adrenal glands in cats with adrenal diseases (six had hyperaldosteronism and four had pituitary-dependent hyperadrenocorticism) and a descriptive comparison with the reference features obtained in the control groups from the prospective study. Cats with hyperaldosteronism presented with unilateral severely enlarged adrenal glands. However, a normal contralateral gland did not preclude a contralateral infiltration in benign or malignant adrenal neoplasms. The ultrasonographic appearance of the adrenal glands could not differentiate benign and malignant lesions. The ultrasonographic appearance of pituitary-dependent hyperadrenocorticism was mainly a symmetrical adrenal enlargement; however, a substantial number of cases were within the reference intervals of adrenal size.

    Abstract: Cancer patients experience weight loss for a variety of reasons, commencing with the tumor's metabolism (Warburg effect) and proceeding via cachexia to loss of appetite. In pancreatic cancer, several other factors are involved, including a loss of appetite with a particular aversion to meat and the incapacity of the pancreatic gland to function normally when a tumor is present in the pancreatic head. Pancreatic exocrine insufficiency is characterized by a deficiency of the enzymes secreted from the pancreas due to the obstructive tumor, resulting in maldigestion. This, in turn, contributes to malnutrition, specifically a lack of fat-soluble vitamins, antioxidants, and other micronutrients. Patients with pancreatic cancer and pancreatic exocrine insufficiency have, overall, an extremely poor prognosis with regard to surgical outcome and overall survival. Therefore, it is crucial to be aware of the mechanisms involved in the disease, to be able to diagnose pancreatic exocrine insufficiency early on, and to treat malnutrition appropriately, for example, with pancreatic enzymes.

    An insufficiency fracture of the tibial plateau may be the cause of knee pain in patients with osteoporosis. The diagnosis is usually not suspected until a bone scan is done, as initial radiographs are often negative or inconclusive and clinical findings are nonspecific and may simulate osteoarthritis or spontaneous osteonecrosis. In five of 165 patients referred for bone scans due to nontraumatic knee pain, a characteristic pattern of intense augmented uptake of radionuclide confined to the tibial plateau led to a presumptive diagnosis of insufficiency fracture, later confirmed on radiographs.

    Incompetent superficial veins are the most common cause of lower extremity superficial venous reflux and varicose veins; however, incompetent or insufficient perforator veins are the most common cause of recurrent varicose veins after treatment, often unrecognized. Perforator vein insufficiency can result in pain, skin changes, and skin ulcers, and often merit intervention. Minimally invasive treatments have replaced traditional surgical treatments for incompetent perforator veins. Current minimally invasive treatment options include ultrasound guided sclerotherapy (USGS) and endovascular thermal ablation (EVTA) with either laser or radiofrequency energy sources. Advantages and disadvantages of each modality and knowledge on these treatments are required to adequately address perforator venous disease. PMID:28123979

    Primary hyperaldosteronism due to aldosterone secreting adrenal adenomas is an important and potentially curable cause for hypertension. The differentiation between unilateral or bilateral adrenal adenomas is crucial, as unilateral adenomas can easily be cured by surgery whereas bilateral adenomas have to be treated conservatively. Exact diagnosis can be made when unilateral or bilateral hormone production is proven with adrenal vein sampling. We present an effective step-by-step technique how to perform an adrenal vein sampling with a special emphasis on how to reliably catheterize the right adrenal vein using Dyna CT.

The object of this investigation is to study the biotransformation of o,p{prime}-DDD and p,p{prime}-DDD in dogs and bovine adrenal cortex to explain its selective toxicity and mechanism of action. The in vitro biotransformation of {sup 14}C-labeled o,p{prime}-DDD and p,p{prime}-DDD by dog and bovine adrenal cortex as studied. Of the cortex subcellular fractions, the cytosol fraction was found to be the most active in metabolizing the substrates, followed by the mitochondrial fraction. This metabolism including that in cytosolic fractions, did not take place with boiled enzyme preparations and required an NADPH generating system. This study has been directed towards establishing the metabolic activation mechanism which may account for the adrenocorticolytic effect of mitotane in contrast to detoxication by the liver. HPLC and TLC metabolic profiles have been generated from incubations of bovine and dog adrenal cortex homogenates and their subfractions for {sup 14}C-labeled p,p{prime}-DDD, o,p{prime}-DDD and its monochloroethylene derivative, o,p{prime}-DDMU.

    Laparoscopic adrenalectomy has been rapidly accepted for treatment of benign adrenal tumors. To evaluate the advantages of laparoscopic adrenalectomy, we examined 55 patients who underwent laparoscopic adrenalectomy. In all patients, adrenal tumors were successfully removed. The mean operating time was 143 minutes, and the estimated mean blood loss was 49 mL in all patients. The postoperative course was uneventful in all cases. The mean frequency of administration of analgesics was only 2.9 times, and the time elapsed to first walking after surgery was 17 hours. The peak white blood cell count and C-reactive protein values after surgery were 8,266 +/- 1,963/mm3 and 2.5 +/- 1.2 mg/dL, respectively. Of the 55 patients, 44 underwent total adrenalectomy and another 11 underwent partial adrenalectomy, which was introduced in the expectation of preserving normal adrenal cortex; it is therefore indicated in solitary and peripherally located benign tumors. The mean operating time was 154 minutes for the total adrenalectomy, which was longer than that of partial adrenalectomy (92 minutes). The estimated blood loss was 50 mL for the total and 46 mL for the partial adrenalectomy. The postoperative course was uneventful and surgical outcome was excellent in each group. In conclusion, our results are encouraging enough to suggest that laparoscopic adrenalectomy should be a preferential therapeutic option for benign adrenal tumors; also, partial adrenalectomy could be a safe, effective, and less invasive procedure in selected cases.

    A 60-year-old male patient with hypertension was referred to our hospital because of insufficient blood pressure control (190/98 mmHg) and to rule out secondary hypertension. A computed tomography scan revealed no adrenal tumor but a large liver mass (5 x 5 cm), and magnetic resonance imaging showed a high signal intensity lesion on the T2-weighted image. Twenty-four hour urinary excretion of catecholamine metabolites was markedly increased, although a 123I-metaiodobenzyl guanidine (MIBG) scintigram failed to show accumulation in the hepatic mass, and no difference was noted between the catecholamine concentration in the tumor-drainage vein and that obtained from the vein draining from the non-tumor area. Liver biopsy did show features compatible with pheochromocytoma (i.e., chromogranin A-positive cells). Transcatheter arterial embolization of the liver tumor was conducted and resulted in a marked (50%) decrease in the 24-h urine normetanephrine excretion. Several metastatic foci were noted in the spinal bone and transcatheter arterial embolization (TAE) was also conducted with successful results. Thus, we experienced a case of primary malignant hepatic pheochromocytoma with negative 123I-MIBG scanning.

    Context: P450 oxidoreductase deficiency (PORD) is a unique congenital adrenal hyperplasia variant that manifests with glucocorticoid deficiency, disordered sex development (DSD), and skeletal malformations. No comprehensive data on genotype-phenotype correlations in Caucasian patients are available. Objective: The objective of the study was to establish genotype-phenotype correlations in a large PORD cohort. Design: The design of the study was the clinical, biochemical, and genetic assessment including multiplex ligation-dependent probe amplification (MLPA) in 30 PORD patients from 11 countries. Results: We identified 23 P450 oxidoreductase (POR) mutations (14 novel) including an exonic deletion and a partial duplication detected by MLPA. Only 22% of unrelated patients carried homozygous POR mutations. p.A287P was the most common mutation (43% of unrelated alleles); no other hot spot was identified. Urinary steroid profiling showed characteristic PORD metabolomes with variable impairment of 17α-hydroxylase and 21-hydroxylase. Short cosyntropin testing revealed adrenal insufficiency in 89%. DSD was present in 15 of 18 46,XX and seven of 12 46,XY individuals. Homozygosity for p.A287P was invariably associated with 46,XX DSD but normal genitalia in 46,XY individuals. The majority of patients with mild to moderate skeletal malformations, assessed by a novel scoring system, were compound heterozygous for missense mutations, whereas nearly all patients with severe malformations carried a major loss-of-function defect on one of the affected alleles. Conclusions: We report clinical, biochemical, and genetic findings in a large PORD cohort and show that MLPA is a useful addition to POR mutation analysis. Homozygosity for the most frequent mutation in Caucasians, p.A287P, allows for prediction of genital phenotype and moderate malformations. Adrenal insufficiency is frequent, easily overlooked, but readily detected by cosyntropin testing. PMID:22162478

    Tumors originating from ectopic adrenal tissue are relatively rare. In this article, we describe a case with Cushing's syndrome caused by an ectopic adrenal adenoma. A 38 year-old male patient presenting with cushingoid appearance for 2 years was diagnosed to have ACTH-independent Cushing's syndrome based on endocrinological evaluation. Mutiple radiological examinations detected bilateral adrenal atrophy. When the images were investigated in a more expanded scope, a 3.0×3.5×5.3 cm mass was detected in the anterior of left renal hilum and left renal vein. The mass was successfully resected with intraoperative endoscopy and pathological evaluation revealed an ectopic adrenal tumor. It is suggested that when the endocrinlogically confirmed adrenal neoplasm could not be well and definitely localized, the possibility of ectopic adrenal should be presumed and further radiography examinations should extend to the field where ectopic adrenal usually presents.

    Adrenal myelolipomas (AMLs) are rare, benign neoplasms of the adrenal gland with varied clinical presentations. The rarity of these tumors precludes any case-controlled or randomized study into their management. The available literature is limited to case reports and short series from referral centers. This review is an effort to put the available literature into perspective such that clinical decision making can be done with some clarity. The PubMed and Cochrane databases were searched with key words Adrenal Myelolipoma, Adrenal Incidentaloma (AI) and Adrenal Collision Tumor (ACT). From over 1300 search results, 547 relevant publications dating from 1954 to 2014 were reviewed. Details of about 1231 AMLs in the indexed literature were analyzed. Increasing usage of imaging studies has significantly increased the discovery of AMLs. Although AMLs are benign tumors, those measuring larger than 6 cm are prone to rupture and hemorrhage. Thorough endocrine work-up may benefit a selected group of patients, especially those who are hypertensive, diabetic/pre-diabetic, young patients (<50 years) and those with bilateral AML. Regular observation is needed for AML patients who are being treated non-operatively, as many of them may require surgery during follow-up. Although the AACE/AAES guidelines for AI (2009) exclude AML from mandatory metabolic work-up for a newly discovered AI, we feel that a significant number of patients with AML would benefit from metabolic work-up. In the literature, endocrine dysfunction in AML is 7% as compared with 11% in AI. Endocrine dysfunction in AML is probably underdiagnosed. PMID:25878407

  2. Genetics of primary ovarian insufficiency: a review.

    Primary ovarian insufficiency is one of the main causes of female infertility owing to an abnormal ovarian reserve. Its relevance has increased in more recent years due to the fact that age of motherhood is being delayed in developed countries, with the risk of having either primary ovarian insufficiency or less chances of pregnancy when women consider the option of having their first baby. Several exogenous factors can lead to this event, such us viral infections, metabolomic dysfunction, autoimmune diseases, and environmental or iatrogenic factors, although in most cases the mechanism that leads to the disorder is unknown. Genetic factors represent the most commonly identified cause and the impact of sex chromosome abnormalities (e.g., Turner syndrome or X structural abnormalities), autosomal and X-linked mutations on the genesis of primary ovarian insufficiency has also been well described. Yet in most cases, the genetic origin remains unknown and there are multiple candidate genes. This review aims to collect all the genetic abnormalities and genes associated with syndromic and non syndromic primary ovarian insufficiency that have been published in the literature to date using the candidate-gene approach and a genome-wide analysis.

    P450c17 enzyme catalyses two different reactions: the 17α-hydroxylation of progesterone and pregnenolone, and segmenting the carbon 17-20 binding from the 17,20lyase producing adrenal androgens. This enzyme is coded by the CYP17A1 gene. The case is presented of a 14 year old patient with delayed pubertal development and a high blood pressure for height and age. 46,XX karyotype. Hormonal studies highlighted hypergonadotropic hypogonadism, adrenal insufficiency and mineralocorticoid excess. Subsequent genetic studies showed a homozygous mutation in the CYP17A1 gene (c.753+G>A), not previously described, which is responsible for the pathophysiology of 17α-hydroxylase deficiency. This entity is a rare form of congenital adrenal hyperplasia. The disease often goes unnoticed until adolescence or early adult life, and should be suspected in 46,XY individuals with ambiguous genitalia or 46,XX with delayed puberty associated with hypertension and/or hypokalaemia.

    To provide practical anatomic data for the imaging diagnosis and surgical treatment of adrenal disease, we investigated the anatomy of the adrenal gland and its relationships to regional structures using 31 sets of serial coronal sections of upper abdomen of Chinese adult cadavers and correlated coronal magnetic resonance (MR) images of ten upper abdomens of adult healthy volunteers and coronal reconstructed multislice spiral computed tomography (MSCT) images of five patients without lesions in the adrenal gland. The adrenal glands were visualized mainly on the successive coronal sections between 18 mm anterior to the posterior margin of inferior vena cava and 24 mm posterior to the posterior margin of inferior vena cava. In general, the left adrenal gland was visualized two sections earlier than the right adrenal gland. On the plane through the anterior parts of bilateral renal hili (A18), the appearance rate of bilateral adrenal glands was 100%, and the maximal measurements of bilateral adrenal glands were visualized. The length, width, thickness of right adrenal body, thickness of medial limb and lateral limb were, respectively, 34.02 +/- 2.12 mm, 10.91 +/- 0.89 mm, 5.82 +/- 0.26 mm, 2.78 +/- 0.08 mm, 2.62 +/- 0.06 mm, whereas the measurements of left adrenal gland were 28.31 +/- 2.46 mm, 18.40 +/- 1.06 mm, 6.84 +/- 0.24 mm, 3.02 +/- 0.08 mm, 2.86 +/- 0.07 mm, respectively. The coronal plane has superior advantage in showing the bilateral adrenal glands. The shapes of adrenal glands are various, whereas the range of adrenal thickness is quite narrow. The thickness of adrenal medial and lateral limbs, especially the thickness of lateral limb are useful for the diagnosis of the bilateral adrenocortical disease.

  5. Three uncommon adrenal incidentalomas: a 13-year surgical pathology review

    PubMed Central

    2012-01-01

    Background The discovery of adrenal incidentalomas due to the widespread use of sophisticated abdominal imaging techniques has resulted in an increasing trend of adrenal gland specimens being received in the pathology laboratory. In this context, we encountered three uncommon adrenal incidentalomas. The aim of this manuscript is to report in detail the three index cases of adrenal incidentalomas in the context of a 13-year retrospective surgical pathology review. Methods The three index cases were investigated and analyzed in detail with relevant review of the English literature as available in PubMed and Medline. A 13-year retrospective computer-based histopathological surgical review was conducted in our laboratory and the results were analyzed in the context of evidence-based literature on adrenal incidentalomas. Results A total of 94 adrenal specimens from incidentalomas were identified, accounting for 0.025% of all surgical pathology cases. In all 76.6% were benign and 23.4% were malignant. A total of 53 females (56.4%) and 41 males (43.6%) aged 4 to 85 years were identified. The benign lesions included cortical adenoma (43.1%), pheochromocytoma (29.3%) and inflammation/fibrosis/hemorrhage (8.3%). Metastatic neoplasms were the most common malignant lesions (50%) followed by primary adrenocortical carcinomas (31.8%) and neuroblastoma (13.6%). These cases were discovered as adrenal incidentalomas that led to surgical exploration. The three index cases of adrenal incidentalomas with unusual pathologies were encountered that included (a) adrenal ganglioneuroma, (b) periadrenal schwannoma and (c) primary adrenal pleomorphic leiomyosarcoma. These cases are discussed, with a literature and clinicopathological review. Conclusions Adrenal lesions are uncommon surgical specimens in the pathology laboratory. However, higher detection rates of adrenal incidentalomas aided by the ease of laparoscopic adrenalectomy has resulted in increased adrenal surgical specimens

    Inflammatory myofibroblastic tumor (IMT) is an uncommon lesion that shows a wide range of anatomic distribution. The adrenal gland, however, is a distinctly rare site of occurrence. To date, only a few cases of IMT arising in the adrenal gland have been reported in the English literature. Here, we report another case of isolated adrenal IMT. A 34-year-old man presented to the emergency department with a complaint of a sudden severe right-sided back pain. Subsequent computed tomographic scan imaging studies demonstrated a large right adrenal mass associated with a hematoma. The right adrenal gland was resected. Microscopic examination revealed an encapsulated cellular spindle cell proliferation with a prominent inflammatory infiltrate. Immunohistochemically, those spindle cells were diffusely and strongly positive for anaplastic lymphoma kinase-1, and focally and weakly positive for smooth muscle actin. S-100 protein and cytokeratin were negative. The findings were consistent with IMT arising from the adrenal gland. Although IMTs in the adrenal gland are rare, they should be considered in the differential diagnosis of adrenal masses. The clinical behavior of IMTs in general is currently indeterminate and a close clinical follow-up is recommended. The behavior of adrenal IMTs remains uncertain because of rare reported cases and lack of long-term follow-up. Further follow-up of reported cases and recognition of additional new cases is warranted to unmask the true biological behavior of adrenal IMTs.

    A wide spectrum of adrenal gland pathology is seen during bacterial infections. Hemorrhage is particularly associated with meningococcemia, while abscesses have been described with several neonatal infections. We studied adrenal gland histopathology of 65 patients with bacterial infections documented in a variety of tissues by using immunohistochemistry. The infections diagnosed included Neisseria meningitidies, group A streptococcus, Rickettsia rickettsii, Streptococcus pneumoniae, Staphylococcus aureus, Ehrlichia sp., Bacillus anthracis, Leptospira sp., Clostridium sp., Klebsiella sp., Legionella sp., Yersinia pestis, and Treponema pallidum. Bacteria were detected in the adrenal of 40 (61%) cases. Adrenal hemorrhage was present in 39 (60%) cases. Bacteria or bacterial antigens were observed in 31 (79%) of the cases with adrenal hemorrhage including 14 with N. meningitidis, four with R. rickettsii, four with S. pneumoniae, three with group A streptococcus, two with S. aureus, two with B. anthracis, one with T. pallidum, and one with Legionella sp. Bacterial antigens were observed in nine of 26 non-hemorrhagic adrenal glands that showed inflammatory foci (four cases), edema (two cases), congestion (two cases), or necrosis (one case). Hemorrhage is the most frequent adrenal gland pathology observed in fatal bacterial infections. Bacteria and bacterial antigens are frequently seen in adrenal glands with hemorrhage and may play a pathogenic role. Although N. meningitidis is the most frequent bacteria associated with adrenal gland pathology, a broad collection of bacteria can also cause adrenal lesions.

    Exocrine pancreatic insufficiency (EPI) is a syndrome caused by an insufficient amount of pancreatic digestive enzymes in the small intestine. Clinical signs most commonly reported in cats with EPI are weight loss, loose and voluminous stools, steatorrhea, polyphagia, and in some cases a greasy soiling of the hair coat in the perianal region. Serum feline trypsin-like immunoreactivity concentration is the diagnostic test of choice for the diagnosis of affected cats. Treatment of cats with EPI consists of enzyme supplementation with either a powdered pancreatic extract or raw pancreas. Most cats with EPI also have severely decreased serum cobalamin concentrations and may require lifelong parenteral cobalamin supplementation. Most cats respond well to therapy and can have a normal life expectancy and quality of life.

Patients with convergence insufficiency were divided in 3 groups: group 1(34 patients--34.6%) were treated with orthoptic exercises and near point exercises at home, group 2 (34 patients--34.6%) were treated with only near point exercises at home and control group 3 (30 patients--30.8%) without treatment. The result of the treatment of C.I. was good at 25 patients(73.5%) of group 1, at 8 patients(23.5%) of group 2 while in group 3 at only one patient the symptoms disappeared.

    The authors describe their experience concerning collagen implantation in case of glottic insufficiency after cordectomy by the CO2 Laser. Three different kinds of injection are indicated as follows: injection of 3/4 of collagen in the site responding to vocal fold removal on 1/4 in the survival fold after cordectomy with conservation of the thyroarytenoid muscle; implantation of 1/2 in the new fold and 1/2 in the surviving one after cordectomy with removing of the cricoarytenoid muscle; infiltration of the whole material in the residual vocal fold after cordectomy enlarged to the false vocal fold and the ventricule as well. Video laryngoscopic and spectrographic examinations documented good phonatory results after collagen implantation in 19 cases over 21; two cases had a persisting insufficiency depending on the fact they had been previously operated of enlarged cordectomy and the scar tissue was not sufficient for measures and consistency to obtain a satisfactory injection of collagen.

    Cefazolin (7 mg/kg) were administered to 11 children with renal insufficiency and to ten children on hemodialysis. The serum half-life of the drug was progressively prolonged as glomerular filtration rate fell. The serum half-life of cefazolin was variably prolonged in those children on hemodialysis, but their serum levels of cefaxolin had dropped by 35 to 65% during dialysis. Most had no measurable level prior to the next dialysis. Dosage recommendations are made for both groups of patients.

    Thyroparathyroidectomy (TPX) prevents adrenal regeneration hypertension (ARH) in female rats and concomitantly inhibits regeneration of the adrenal cortex. Removal of the thyroid gland plays the major role in preventing ARH inasmuch as parathyroidectomized adrenal-enucleated (PX-AE) rats became hypertensive, whereas thyroparathyroidectomized adrenal-enucleated rats (TPX-AE + PT) did not. Inhibition of adrenocortical regneration by TPX is reflected by a significant decrease in adrenal weight, volume of cortical parenchymal tissue per gland, and average cell volume at three weeks, compared with the regenerating adrenal gland in adrenal-enucleated thyroid-parathyroid-intact (AE) rats. Mitochondria in TPX-AE rats resembled closely those from zona fasciculata cells of a normal adrenal gland; stereologic techniques for electron microscopic examination confirmed that mitochondrial volume/cell and surface area of total mitochondrial membranes/cell (outer/inner membranes plus cristae) of adrenocortical cells from TPX-AE rats did not differ significantly from those of AE animals. The surface area of mitochondrial cristae of TPX-AE rats, however, was significantly greater than that of AE rats, whereas the surface area of the inner/outer mitochondrial membrane of the TPX-AE group was decreased significantly as compared with that of the AE group. The diameter of mitochondria in TPX-AE rats was larger than in the AE group, although the number of mitochondria/cell was significantly less in TPX-AE rats than in AE rats. Although TPX had no significant effect on the levels of DOC or corticosterone in the serum of quiescent AE rats as compared with TPX-AE rats, the rise in DOC in the serum after ether stress was blunted in the TPX-AE group as compared with that in the AE group. The rise in corticosterone in the TPX-AE group was comparable to that of the AE animals. Thus, partial inhibition of adrenal regeneration in TPX-AE rats in combination with a blunted rise in DOC levels in

    Abstract: Cancer patients experience weight loss for a variety of reasons, commencing with the tumor’s metabolism (Warburg effect) and proceeding via cachexia to loss of appetite. In pancreatic cancer, several other factors are involved, including a loss of appetite with a particular aversion to meat and the incapacity of the pancreatic gland to function normally when a tumor is present in the pancreatic head. Pancreatic exocrine insufficiency is characterized by a deficiency of the enzymes secreted from the pancreas due to the obstructive tumor, resulting in maldigestion. This, in turn, contributes to malnutrition, specifically a lack of fat-soluble vitamins, antioxidants, and other micronutrients. Patients with pancreatic cancer and pancreatic exocrine insufficiency have, overall, an extremely poor prognosis with regard to surgical outcome and overall survival. Therefore, it is crucial to be aware of the mechanisms involved in the disease, to be able to diagnose pancreatic exocrine insufficiency early on, and to treat malnutrition appropriately, for example, with pancreatic enzymes.

    Congenital Adrenal Hyperplasia describes a group of autosomal recessive disorders characterized by a decrease in Cortisol production. 11 beta hydroxylase deficiencies is the second most common form. However, its presentation with cholestatic jaundice is extremely rare. We present a case of a 29-day-old infant who came to us with unusual dark complexion, persistent jaundice, and electrolyte imbalance. On investigation he was diagnosed as a case of congenital adrenal hyperplasia. Treatment with hydrocortisone and fludrocortisone cleared his jaundice and complexion with subsequent improvement in electrolytes. The aim of this report is to illustrate an unusual presentation of CAH with Cholestatic jaundice. This is the first case to be reported from Pakistan. The case outlines the difficult workup that was encountered in the diagnosis and management of the patient.

    Cushing syndrome (CS) in children is a rare disorder that is most frequently caused by an adrenal tumour or a pituitary corticotrophin-secreting adenoma. The management is challenging and requires an individualised approach and multidisciplinary care. We present the case of a 23-month-old female child with a history of excessive weight gain, growth failure, hirsutism, acne and behavioural difficulties. Investigations revealed elevated serum midnight cortisol and 24 h urinary free cortisol. Overnight dexamethasone suppression testing showed no suppression of cortisol levels. Abdominal imaging revealed a right-sided suprarenal mass. She underwent right adrenalectomy and the histology showed an adrenal cortical carcinoma. There was clinical improvement with catch-up growth and weight normalisation. Despite being rare in clinical practice, in a child with weight gain, hirsuitism and growth failure the diagnosis must be considered. The overall prognosis of CS in childhood is good, but challenges remain to ensure normal growth and body composition. PMID:22927284

    Anterior pituitary corticotrophin cells secrete ACTH as part of a larger precursor molecule, pro-opiomelanocortin. Post-translational cleavage of this precursor yields three major peptides: ACTH, beta-LPH and N-POMC. Experiments both in vivo and in vitro suggest that N-POMC may act as a prohormone amplifier for ACTH-induced adrenal steroidogenesis and as regulator of adrenocortical cell growth. The secretion of POMC is under the control of CRF. These findings are discussed in relation to the pathophysiology of corticotrophinoma. The primary defect in this condition appears to reside at the level of the anterior pituitary cell and is readily amenable to treatment by trans-sphenoidal microsurgery. The estimation of plasma ACTH concentrations is proving useful in the monitoring of various clinical conditions including Addison's disease and congenital adrenal hyperplasia.

    Patient: Female, 60 Final Diagnosis: UPSC with adrenal metastasis Symptoms: Post menopausal bleeding Medication: — Clinical Procedure: Adrenalectomy Specialty: Oncology Objective: Rare disease 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

    Achalasia is a rare primary motility disorder of esophagus; treatments include endoscopic balloon dilatation (EBD) and laparoscopic Heller's cardiomyotomy (LC). This study compared EBD versus LC for treatment of achalasia with focus on quality of life (QoL) and prevalence of post-treatment gastroesophageal reflux disease. This was a retrospective cohort study of all patients diagnosed with achalasia older than 16 treated with either EBD or LC from January 1998 to April 2008. Patients' demographic data, comorbidities, postintervention GERD symptoms, QoL, recurrence of dysphagia, reintervention rate, hospital stay, and time to resumption of diet were collected. Sixty-eight patients were recruited into the study (EBD n= 50; LC n= 18). A significant improvement in QoL was found in patients undergoing LC (0.917 vs. 0.807, P= 0.006). A higher proportion of patients treated with EBD developed post-treatment gastroesophageal reflux symptoms (60.5% vs. 43.8%) when compared with LC, although statistically insignificant (P= 0.34). Patients treated with balloon dilatation had a greater percentage of recurrence of dysphagia (55.1% vs. 26.7%; P= 0.235) and need of reintervention (42.1% vs. 9.1%; P= 0.045). However, these patients had a shorter median hospital stay (1d [range 0-4]) and earlier resumption of diet (0d [range 0-3]). Although EBD is associated with a quicker perioperative recovery, LC accomplished a better QoL, lower incidence of recurrence of dysphagia, and need of reintervention after treatment for achalasia.

    We present a case of synchronous malignant pheochromocytoma in bilateral adrenal glands. A 73- year-old man presented to our hospital with bilateral adrenal masses incidentally found during abdominal ultrasonography examination for an unrelated issue. The patient had a 30-year history of hypertension and paroxysmal atrial fibrillation. Computed tomography and magnetic resonance imaging showed heterogeneous tumors in bilateral adrenal glands and an enlarged para-aortic lymph node. Hormonal examinations revealed a high value of urinary catecholamines. Metaiodobenzylguanidine (MIBG) scintigraphy showed increased uptake in bilateral adrenal glands and the lymph node. Both adrenal tumors and the node were surgically removed. Pathological examination revealed histologically distinct tissue between the two adrenal tumors. The patient received five cycles of adjuvant chemotherapy, consisting of cyclophosphamide, vincristine, and dacarbazine. The patient has been in remission for 32 months following surgical treatment.

    The era of sophisticated high resolution imaging with the consequent identification of previously unrecognised adrenal masses (adrenal incidentalomas), has emphasised the need for an appropriate biochemical approach to define adrenal function. The focus of this testing is on catecholamines from the adrenal medulla (testing that has been rendered relatively straightforward by plasma metanephrine measurements) and the physiological corticosteroids, cortisol and aldosterone, synthesised by the adrenal cortex. The diagnosis of hypercortisolism remains a challenge and has been extensively reviewed. In the context of hypertension and an adrenal incidentaloma, the exclusion of hyperaldosteronism has an importance beyond simple blood pressure control. This review focuses on the recommended approaches to both the diagnosis of hyperaldosteronism and the characterisation of its aetiology. Monogenetic causes of mineralocorticoid hypertension are discussed as are recent developments with respect to both the molecular aetiology and the differential diagnosis of aldosterone-producing adenomas.

    Unilateral adrenal hyperplasia is a rare cause of primary hyperaldosteronism (around a 3%) that has surgical treatment. A case of a patient with hypertension resistant to conventional therapy in treatment with 7 drugs who presented with primary hyperaldosteronism due to unilateral adrenal hyperplasia is presented. A left adrenalectomy was performed, and the patient had a good clinical response, with no need of any drug after 2 years of surgery. Unilateral adrenal hyperplasia is a different entity and it is not an asymmetric variant of the bilateral adrenal hyperplasia. In the study of patients with primary hyperaldosteronism and imaging tests with absence of adenoma is a diagnosis that must be considered before cataloguing patients with bilateral adrenal hyperplasia and start a medical treatment, because unilateral adrenal hyperplasia would have a surgical resolution.

    How anti-Müllerian hormone (AMH) and testosterone (T) interrelate in infertile women is currently largely unknown. We, therefore, in a retrospective cohort study investigated how infertile women with high-AMH (AMH ≥75th quantile; n=144) and with normal-AMH (25th-75th quantile; n=313), stratified for low-T (total testosterone ≤19.0ng/dL), normal-T (19.0-29.0ng/dL) and high-T (>29.0ng/dL) phenotypically behaved. Patient age, follicle stimulating hormone (FSH), dehyroepiandrosterone (DHEA), DHEA sulphate (DHEAS), cortisol (C), adrenocorticotrophic hormone (ACTH), IVF outcomes, as well as inflammatory and immune panels were then compared between groups, with AMH and T as variables. We identified a previously unknown infertile PCOS-like phenotype, characterized by high-AMH but, atypically, low-T, with predisposition toward autoimmunity. It presents with incompatible high-AMH and low-T (<19.0ng/dL), is restricted to lean PCOS-like patients, presenting delayed for tertiary fertility services. Since also characterized by low DHEAS, low-T is likely of adrenal origina, and consequence of autoimmune adrenal insufficiency since also accompanied by low-C and evidence of autoimmunity. DHEA supplementation in such patients equalizes low- to normal-T and normalizes IVF cycle outcomes. Once recognized, this high-AMH/low-T phenotype is surprisingly common in tertiary fertility centers but, currently, goes unrecognized. Its likely adrenal autoimmune etiology offers interesting new directions for investigations of adrenals control over ovarian function via adrenal androgen production.

    Introduction Adrenal incidentalomas are defined as masses picked up on imaging studies that were done for apparently different reasons. With frequent use of imaging modalities, incidental adrenal masses are commonly encountered in clinical practice. Guidelines are currently available for the diagnosis and management of adrenal incidentalomas, but the appropriateness of initial work-up and subsequent follow-up of incidental adrenal masses in the community hospital setting is unknown. Objective We studied the appropriateness of initial work-up and follow-up of incidental adrenal masses discovered on abdominal computerized tomography (CT). Methods In our retrospective study, we reviewed sequential CT scans of the abdomen performed in the month of January 2010 at a community hospital. Once patients with one or more adrenal masses were identified, outpatient charts for initial biochemical testing and follow-up imaging were obtained either through directly accessing the electronic medical records or through contacting primary care physician's offices. Patient charts were reviewed to assess the data for the next 2 years following the discovery of an adrenal abnormality. Results Twenty adrenal masses were incidentally discovered on 723 abdominal CTs performed within the month of January 2010 resulting in an overall incidence of 2.76%. Of the patients with incidentally discovered adrenal masses, appropriate biochemical and follow-up imaging were only performed in patients referred to an endocrinologist (2 of 20 patients). Thirty percent of patients with incidental masses received a repeat CT scan for non-adrenal reasons, and no change in the mass size was noted. Conclusion Despite published guidelines, the initial work-up and follow-up of patients with an incidentally discovered adrenal mass is unsatisfactory. There is a desperate need for education of providers regarding appropriate work-up of incidental adrenal masses. PMID:27802863

    Computed tomography has become an important diagnostic modality in the preoperative staging of patients with bronchogenic carcinoma. The adrenal glands represent one of the most frequent sites of metastasis. Therefore, an isolated adrenal mass discovered on preoperative thoracoabdominal CT poses a diagnostic problem. Three hundred thirty patients with histologically proved nonsmall-cell bronchogenic carcinoma were evaluated. Thirty-two had adrenal masses without further evidence of disease in the abdomen, Eight of these 32 masses were metastases, 17 were proved adenomas, and 7 did not undergo biopsy. Thus an isolated adrenal mass is more likely benign than metastatic, and biopsy is advocated prior to withholding potentially curative surgery.

    Histological structures and morphometric and some histochemical indicators of elk's adrenal gland development as subspecies of red deer in prenatal and postnatal ontogenies stages was studied. It was found that the growth of the fetus adrenal glands weight and the thickness of the structures adrenal glands fragments continue throughout the prenatal period of ontogeny. The cells of androgenic zone with single wandering sympathogoniae are differentiated in the adrenal glands in the second month of development. The androgenic and definite zone and the adrenal medulla are differentiated by the third month of development. At the 4 months, adrenal gland cortex zona glomerulosa and zona fasciculate-reticularis are differentiated; zona reticularis is differentiated only by the seventh month. By the eighth month, the structure of adrenal glands corresponds to the adrenal glands of a newborn. Full structural formation of the adrenal glands takes place in young animals by age 1.5. Obvious structural changes were not found late in the postnatal stages of development.

    Most adrenal tumors are found incidentally and appear as small solitary nodules on abdominal imaging. Occasionally, work-up demonstrates multifocal or bilateral adrenal tumors. Certain patients are predisposed to multiple lesions, such as those with hereditary forms of pheochromocytoma as seen in von Hippel-Lindau disease, multiple endocrine neoplasia type II, and von Recklinghausen's disease. Partial rather than total adrenalectomy should be considered for these patients in an attempt to preserve endogenous adrenocortical function. Partial adrenalectomy has also been used to resect other types of adrenal tumors, especially in patients with a solitary adrenal gland. A discussion of the indications for partial adrenalectomy and of the surgical technique follows.

    Adrenal crisis occurs when there is decreased secretions of steroid hormones (mainly cortisol) from the adrenal glands due to varied reasons. It may arise due to a primary adrenal condition or due to decreased hormonal signals from the pituitary secondary to a hypofunctioning pituitary. Hypopituitarism may result due to direct causes like trauma, tumour, infection or it may be due to some vascular insult as seen in Sheehan syndrome. We report an unusual presentation of Sheehan syndrome in the form of life-threatening adrenal crisis precipitated by the usage of rifampicin. PMID:24339502

    A 29-yr-old man, presented with abdominal pain and fever, had an initial computed tomography (CT) scan revealing low attenuation of both adrenal glands. The initial concern was for tuberculous adrenalitis or autoimmune adrenalitis combined with adrenal hemorrhage. The patient started empirical anti-tuberculous medication, but there was no improvement. Enlargement of cervical lymph nodes were developed after that and excisional biopsy of cervical lymph nodes was performed. Pathological finding of excised lymph nodes was compatible to NK/T-cell lymphoma. The patient died due to the progression of the disease even after undergoing therapeutic trials including chemotherapy. Lymphoma mainly involving adrenal gland in the early stage of the disease is rare and the vast majority of cases that have been reported were of B-cell origin. From this case it is suggested that extra-nodal NK/T-cell lymphoma should be considered as a cause of bilateral adrenal masses although it is rare.

    A 64-year-old woman presented with contralateral right adrenal metastasis with adrenal vein thrombus, which was diagnosed many years after left nephrectomy with adrenalectomy due to renal cell cancer. The patient underwent right adrenalectomy with adrenal vein tumor thrombectomy for treatment. The pathologic examination confirmed metastatic clear cell carcinoma. The remote but existing risk of developing contralateral adrenal metastasis (CAM) after primary radical nephrectomy supports the idea of sparing the adrenal gland in suitable patients who undergo radical nephrectomy. Contralateral adrenal metastasis from RCC is a rare finding with the potential benefit of cure after resection. Care must be taken in preoperative diagnostics, as this metastasis is capable of causing inferior vena cava tumor thrombus via the suprarenal venous route. According to our knowledge, our case is the second similar entity described in literature so far. PMID:26807301

    2003-02-01

    Adrenalectomy has become the standard of care for the management of hormonally active adrenal masses. Various surgical therapies have been proposed to excise completely or destroy these adrenal lesions, which may be benign or malignant. New minimally invasive, adrenal-sparing procedures have recently been introduced, among them laparoscopic partial adrenalectomy, cryosurgery, and radiofrequency ablation. These procedures focus on reducing patient morbidity and hastening postoperative recovery while preserving normal adrenal tissue. However, questions remain about the risks and benefits associated with routine application of minimally invasive therapies for adrenal-sparing surgery in terms of complete tumor extirpation. Clearly, more experience and longer follow-up is necessary to validate these procedures. Herein we describe the surgical techniques and early results of treatment with adrenal-sparing surgery.

    Velopharyngeal insufficiency (VPI) can occur in the setting of an unrepaired or repaired cleft lip and palate. The rate of VPI has been documented as high as 33% in some studies with higher rates of recurrences following surgery associated with genetic syndromes such as 22q11.2 deletions. The primary cause of VPI in these groups is still identified as the anatomic abnormalities of the velum. In this review, the anatomy and physiology of the velum are discussed along with genetic mutations associated with VPI. PMID:27617110

    Maternal adrenal cortical carcinoma in pregnancy is rare. We report a case of an infant born to a mother with a history of adrenal cortical carcinoma. The pregnancy was complicated by fetal exposure to mitotane and dexamethasone. Despite the potential teratogenic exposures, there was no evidence of adrenal dysfunction in the infant. Growth and development at 12 months of age are normal and prognosis appears favorable. The long-term impact of fetal exposure to mitotane and glucocorticoid requires further investigation.

    Introduction Peroral endoscopic myotomy (POEM) has been considered as a minimal-invasive, innovative technique for long-term treatment of all types of esophageal achalasia and other esophageal motility disorders. Patients and methods We report on 20 consecutive Greek patients with manometrically proved esophageal achalasia (14 patients with type I, 4 with type II, 2 with type III, and 4 with sigmoid esophagus), with an age range of 32–92 years, mean age 59 years, 12 males, successfully treated by POEM from 2013 to 2015. The Eckardt score was 7–12 (type III). Seventeen (85%) POEM procedures were performed in the Endoscopy Department, according to a previous study. During POEM, CO2 insufflation was mandatory, while the Triangle Tip knife was the only knife used in all procedures. Eckardt score, esophagogram and manometry before and after performing POEM were used for evaluation of our results. The follow-up period was 6 months to 3 years. Results Selective circular myotomy, 10–13 cm in length, was successfully completed in all patients without severe acute or late complications. Three patients (15%) showed moderate pneumomediastinum and pneumoperitoneum, which was successfully managed by abdominal needle drainage during the procedure. One patient showed mild pleural collection, and in one patient the clip–endoloop technique was used to successfully close the mucosal entry after the completion of POEM. The outcome was uneventful without any further clinical consequences. No other short- or long-term serious complications were reported. Patients were discharged after 1–3 days of hospitalization. Six months to 3 years after the POEM procedure, all patients were alive; the majority (90%) had complete clinical improvement, while two patients with sigmoid-type achalasia showed moderate-to-significant clinical improvement. Erosive esophagitis was reported in 15%. Conclusion Our results are in accordance with international data, and proved the safety and efficacy

  18. Varicose veins and chronic venous insufficiency.

    2009-11-01

    Varicose veins are a very frequent disorder with prevalence in our adult population between 14% for large varices and 59% for small teleangiectasias. Subjective symptoms may be very non-specific. The term "chronic venous insufficiency (CVI)" defines functional abnormalities of the venous system producing advanced symptoms like oedema, skin changes or leg ulcers. Both entities, varicose veins and CVI, may be summarized under the term "chronic venous disorders" which includes the full spectrum of morphological and functional abnormalities of the venous system. A classification system to describe chronic venous disorders regarding clinical appearance, etiology, anatomical distribution and pathophysiology has been proposed under the acronym of CEAP. The revised version of the CEAP classification contains also definitions of clinical signs and suggests three levels of apparative investigations adjusted to the clinical stage. Concerning the etiology of venous disorders controversial theories exist leading to different therapeutic concepts. As a matter of fact there is a vicious circle between structural changes in valves and venous wall and hemodynamic forces leading to reflux and venous hypertension. Different methods for treating varicose veins are available producing satisfactory early outcome in most cases, but followed by a high recurrence rate after years. Chronic venous insufficiency requires "chronic management". Compression therapy by bandages for initial treatment of severe stages and maintenance therapy using medical compression stockings is essential. In addition correction of venous refluxes by surgery or endovenous procedures including echo-guided foam sclerotherapy should be considered in every single case.

    Smith-Lemli-Opitz syndrome (SLOS) is a multiple malformation syndrome due to mutations of the 7-dehydrocholesterol reductase gene (DHCR7), which leads to a deficiency of cholesterol synthesis and an accumulation of 7-dehydrocholesterol and related metabolites. The SLOS clinical spectrum ranges from multiple major malformations to a mild phenotype with dysmorphic features, intellectual disability and a specific behavioral presentation. Several cases of SLOS with adrenal insufficiency have been described. We performed ovine corticotropin (oCRH) testing in 35 SLOS patients and 16 age- and gender-matched controls. We reviewed prior ACTH stimulation tests of our SLOS patients (19 of 35 available) and reviewed ACTH stimulation tests from additional 10 other SLOS patients. Results from oCRH testing showed that patients with SLOS had significantly higher ACTH baseline values than healthy controls (24.8 ± 15.3 pg/mL vs. 17.8 ± 7.5 pg/mL, p=0.034). However, no statistically significant differences were noted for peak ACTH values (74.4 ± 35.0 pg/mL vs. 64.0 ± 24.9 pg/mL, p=0.303) and for baseline (14.2 ± 7.8 mcg/dL vs. 14.2 ± 6.3 mcg/dL, p=0.992) and peak cortisol values (28.2 ± 7.9 mcg/dL vs. 24.8 ± 8.1 mcg/dL, p=0.156). The area-under-the-curve (AUC) was not significantly different in SLOS patients compared to controls for both ACTH (250.1 ± 118.7 pg/mL vs. 195.3 ± 96.6 pg/mL, p=0.121) as well as cortisol secretion (83.1 ± 26.1 mcg/dL vs. 77.8 ± 25.9 mcg/dL, p=0.499). ACTH stimulation test was normal in 28 of 29 tests. The individual with the abnormal ACTH stimulation test had a normal oCRH test during the same evaluation. The slightly increased baseline ACTH level seen during oCRH testing may be due to compensated mild adrenocortical insufficiency. However, we were able to show that our cohort affected with SLOS had an adequate stress response and that in mild to moderate cases of SLOS stress steroid coverage should not be required.

    The mammalian circadian timing system consists of a master pacemaker in the suprachiasmatic nucleus (SCN) and subordinate clocks that disseminate time information to various central and peripheral tissues. While the function of the SCN in circadian rhythm regulation has been extensively studied, we still have limited understanding of how peripheral tissue clock function contributes to the regulation of physiological processes. The adrenal gland plays a special role in this context as adrenal hormones show strong circadian secretion rhythms affecting downstream physiological processes. At the same time, they have been shown to affect clock gene expression in various other tissues, thus mediating systemic entrainment to external zeitgebers and promoting internal circadian alignment. In this review, we discuss the function of circadian clocks in the adrenal gland, how they are reset by the SCN and may further relay time-of-day information to other tissues. Focusing on glucocorticoids, we conclude by outlining the impact of adrenal rhythm disruption on neuropsychiatric, metabolic, immune, and malignant disorders.

    Objective To assess the feasibility and reliability of apparent diffusion coefficient (ADC) measurements of normal adrenal glands. Materials and methods This was a retrospective study involving 32 healthy subjects, divided into two groups: prepubertal (PreP, n = 12), aged from 2 months to 12.5 years (4 males; 8 females); and postpubertal (PostP, n = 20), aged from 11.9 to 61 years (5 males; 15 females). Diffusion-weighted magnetic resonance imaging (DW-MRI) sequences were acquired at a 1.5 T scanner using b values of 0, 20, 500, and 1000 s/mm2. Two radiologists evaluated the images. ADC values were measured pixel-by-pixel on DW-MRI scans, and automatic co-registration with the ADC map was obtained. Results Mean ADC values for the right adrenal glands were 1.44 × 10-3 mm2/s for the PreP group and 1.23 × 10-3 mm2/s for the PostP group, whereas they were 1.58 × 10-3 mm2/s and 1.32 × 10-3 mm2/s, respectively, for the left glands. ADC values were higher in the PreP group than in the PostP group (p < 0.05). Agreement between readers was almost perfect (intraclass correlation coefficient, 0.84-0.94; p < 0.05). Conclusion Our results demonstrate the feasibility and reliability of performing DW-MRI measurements of normal adrenal glands. They could also support the feasibility of ADC measurements of small structures. PMID:28057963

    Abstract Adrenal hemorrhage (AH) is a rare but life-threatening condition. Small focal hemorrhage may present subclinically, but massive hemorrhage may lead to rapid cardiovascular collapse and ultimately death if not diagnosed appropriately and treated quickly. Most cases reported in the literature have been treated conservatively. In an event of increasing hemorrhage during conservative management, it may be tricky to intervene surgically because of the hematoma around the gland. Here we describe a case where we managed a large spontaneous AH by a combination of angioembolization and laparoscopic adrenalectomy. PMID:27579389

    Experiments clarifying the effects of serotonin (5-HT) in the regulation of the hypothalamic-pituitary-adrenocortical system are surveyed. Lesion experiments which seek to determine functional maps of serotonergic input to areas involved in regulation are reported. Investigations of the effects of 5-HT levels on the plasma ACTH response to stress and the diurnal variation in basal plasma corticosterone are summarized, and the question of whether serotonergic transmission is involved in the regulation of all aspects of pituitary-adrenal function is considered with attention to the stimulatory and inhibitory action of 5-HT.

    2010-01-01

    Congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency is one of the most common autosomal recessive hereditary diseases. The impairment of cortisol synthesis leads to excessive stimulation of the adrenal glands by adrenocorticotropic hormone (ACTH), adrenal hyperplasia, and excessive androgen synthesis. The syndrome is characterised by a considerable correlation between the genotype and the phenotype with the type of CYP21A2 gene mutation affecting the severity of 21-hydroxylase deficiency. The clinical manifestations of CAH in adults result from adrenocortical and adrenomedullary insufficiency, hyperandrogenism, and the adverse effects of glucocorticosteroids used for the treatment of the condition. Non-classic CAH may sometimes be asymptomatic. In patients with classic CAH obesity, hyperinsulinaemia, insulin resistance, and hyperleptinaemia are more often seen than in the general population. These abnormalities promote the development of metabolic syndrome and its sequelae, including endothelial dysfunction, and cardiovascular disease. Long-term glucocorticosteroid treatment is also a known risk factor for osteoporosis. Patients with CAH require constant monitoring of biochemical parameters (17a-hydroxyprogesterone and androstenedione), clinical parameters (body mass, waist circumference, blood pressure, glucose, and lipids), and bone mineral density by densitometry. The principal goal of treatment in adults with CAH is to improve quality of life, ensure that they remain fertile, reduce the manifestations of hyperandrogenisation in females, and minimise the adverse effects of glucocorticosteroid treatment. Patients with classic CAH require treatment with glucocorticosteroids and, in cases of salt wasting, also with a mineralocorticosteroid. Radical measures, such as bilateral adrenalectomy, are very rarely needed. Asymptomatic patients with non-classic CAH require monitoring: treatment is not always necessary.

    Ross, Ian L; Louw, Graham J

    2015-03-01

    In this mini review, the embryological and functional development of the adrenal glands is presented from a molecular perspective. While acknowledging that this is a highly complex series of events, the processes are described in simple and broad strokes in a single text for the reader who is interested in this field but is not an active researcher. The origin of the adrenal glands is in the mesodermal ridge as early as the fourth week of gestation. Between the eighth and ninth weeks of gestation, the adrenal glands are encapsulated and this results in the presence of a distinct organ. There have been great strides in deciphering the very complicated molecular aspects of adrenal gland development in which multiple transcription factors have been identified, directing the adrenogonadal primordium into the adrenal cortex, kidney, or bipotential gonad. Adrenocorticotrophic hormone is critical for early development of the hypothalamic-pituitary adrenal axis. Several mutations in transcription factors, responsible for normal adrenal gland development have been found to induce the familial syndrome of congenital adrenal hypoplasia or neoplasia.

    2011-03-01

    In the last 30 years the development and widespread use of modern imaging techniques has caused a 20-time increase in the diagnosis of adrenal incidentaloma (AI). Among AIs myelolipoma (ML) is reported with a frequency up to 10%. In the literature 8 patients with adrenal masses in thalassaemia or chronic haemolytic anaemia have been reported: five cases were shown to have extramedullary haematopoiesis (EH) and 3 ML. We describe here a case of an adult male affected by beta thalassaemia intermedia and large bilateral lipomatous adrenal masses. The patient was referred to our ward at the age of 55 and underwent hormonal testing, MRI, and SPECT/CT scans. Adrenal masses were hormonally inactive, and fat-containing on MRI and CT scans. SPECT/CT examination with 99mTccolloid demonstrated the presence of marrow tissue. ML and EH are the only two tumours with marrow tissue among lipomatous adrenal masses. In our patient a brown nodular mass was resected and histologically classified as ML. In benign adrenal masses, radiological follow-up is indicated; in case of large bilateral masses adrenal function tests are suggested periodically in order to detect possible adrenal hypofunction.

    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.

    Twenty-nine patients with primary hyperaldosteronism were evaluated with computed tomography (CT), adrenal venous sampling, and adrenal venography. Twenty-three patients had aldosteronomas and six had bilateral adrenocortical hyperplasia. Sixteen (70%) of the adenomas were accurately located by CT. All nodules of 1.5 cm or larger diameter and 50% of nodules 1.0 to 1.4 cm in diameter were demonstrated. Nodules of less than 1.0 cm in diameter generally were not detected. High-resolution CT appeared more sensitive than standard CT (75% vs 58%). Adrenal venous sampling for aldosterone assay was the most sensitive of the three methods, localizing 22 (96%) of the 23 adenomas. Eighteen (78%) of the adenomas were identified by adrenal venography, although two patients with bilateral cortical hyperplasia were mistakenly diagnosed as having a small adenoma. No such false-positive studies were encountered with CT or adrenal venous sampling.

    Many primary cancers can metastasize to the adrenal glands. Adrenalectomy via an open or laparoscopic approach is the current definitive treatment, but not all patients are eligible or wish to undergo surgery. There are only limited studies on the use of conventional radiation therapy for palliation of symptoms from adrenal metastasis. However, the advent of stereotactic body radiation therapy (SBRT) - also named stereotactic ablative radiotherapy for primary lung cancer, metastases to the lung, and metastases to the liver - have prompted some investigators to consider the use of SBRT for metastases to the adrenal glands. This review focuses on the emerging data on SBRT of metastasis to the adrenal glands, while also providing a brief discussion of the overall management of adrenal metastasis.

    Hemorrhagic hypotension produces an increase in adrenal medullary blood flow and a decrease in adrenal cortical blood flow. To determine whether changes in adrenal blood flow during hemorrhage are neurally mediated, the authors compared blood flow responses following adrenal denervation (splanchnic nerve section) with changes in the contralateral, neurally intact adrenal. Carbonized microspheres labeled with /sup 153/Gd, /sup 114/In, /sup 113/Sn, /sup 103/Ru, /sup 95/Nb or /sup 46/Se were used. Blood pressure was reduced and maintained at 60 mmHg for 25 min by hemorrhage into a pressurized bottle system. Adrenal cortical blood flow decreased to 50% of control with hemorrhage in both the intact and denervated adrenal. Adrenal medullary blood flow increased to four times control levels at 15 and 25 min posthemorrhage in the intact adrenal, but was reduced to 50% of control at 3, 5, and 10 min posthemorrhage in the denervated adrenal. In a separate group of dogs, the greater splanchnic nerve on one side was electrically stimulated at 2, 5, or 15 Hz for 40 min. Adrenal medullary blood flow increased 5- to 10-fold in the stimulated adrenal but was unchanged in the contralateral, nonstimulated adrenal. Adrenal cortical blood flow was not affected by nerve stimulation. They conclude that activity of the splanchnic nerve profoundly affects adrenal medullary vessels but not adrenal cortical vessels and mediates the observed increase in adrenal medullary blood flow during hemorrhagic hypotension.

    Feline hyperthyroidism is potentially associated with exaggerated responsiveness of the adrenal gland cortex. The adrenal glands of 23 hyperthyroid cats were examined ultrasonographically and compared to the adrenal glands of 30 control cats. Ten hyperthyroid cats had received antithyroid drugs until 2 weeks before sonography, the other 13 were untreated. There was no difference in adrenal gland shape between healthy and hyperthyroid cats: bean-shaped, well-defined, hypoechoic structures surrounded by a hyperechoic halo in 43/60 (71.6%) healthy cats and 34/46 (73.9%) hyperthyroid cats; more ovoid in 13/60 (21.6%) healthy cats and 9/46 (19.6%) hyperthyroid cats while more elongated in 4/60 (6.7%) healthy cats, 3/46 (6.5%) hyperthyroid cats. Hyperechoic foci were present in 9/23 (39.1%) hyperthyroid cats and 2/30 (6.7%) healthy cats. The adrenal glands were significantly larger in hyperthyroid cats, although there was overlap in size range. The mean difference between hyperthyroid cats and healthy cats was 1.6 and 1.7 mm in left and right adrenal gland length, 0.8 and 0.9 mm in left and right cranial adrenal gland height, and 0.4 and 0.9 mm in left and right caudal adrenal gland height. There was no significant difference between the adrenal gland measurements in treated and untreated hyperthyroid cats. The adrenomegaly was most likely associated with the hypersecretion of the adrenal cortex documented in hyperthyroid cats. Hyperthyroidism should be an alternative to hyperadrenocorticism, hyperaldosteronism, and acromegaly in cats with bilateral moderate adrenomegaly.

  3. Adrenal G protein-coupled receptor kinase-2 in regulation of sympathetic nervous system activity in heart failure.

    PubMed

    2015-09-26

    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.

  4. Transgenic Expression of Ad4BP/SF-1 in Fetal Adrenal Progenitor Cells Leads to Ectopic Adrenal Formation

    2009-01-01

    Deficiency of adrenal 4 binding protein/steroidogenic factor 1 (Ad4BP/SF-1; NR5A1) impairs adrenal development in a dose-dependent manner, whereas overexpression of Ad4BP/SF-1 is associated with adrenocortical tumorigenesis. Despite its essential roles in adrenal development, the mechanism(s) by which Ad4BP/SF-1 regulates this process remain incompletely understood. We previously identified a fetal adrenal enhancer (FAdE) that stimulates Ad4BP/SF-1 expression in the fetal adrenal gland by a two-step mechanism in which homeobox proteins initiate Ad4BP/SF-1 expression, which then maintains FAdE activity in an autoregulatory loop. In the present study, we examined the effect of transgenic expression of Ad4BP/SF-1 controlled by FAdE on adrenal development. When Ad4BP/SF-1 was overexpressed using a FAdE-Ad4BP/SF-1 transgene, FAdE activity expanded outside of its normal field, resulting in increased adrenal size and the formation of ectopic adrenal tissue in the thorax. The increased size of the adrenal gland did not result from a corresponding increase in cell proliferation, suggesting rather that the increased levels of Ad4BP/SF-1 may divert uncommitted precursors to the steroidogenic lineage. The effects of FAdE-controlled Ad4BP/SF-1 overexpression in mice provide a novel model of ectopic adrenal formation that further supports the critical role of Ad4BP/SF-1 in the determination of steroidogenic cell fate in vivo.

    Great discrepancies are often encountered between the distance fixation and the near-fixation esodeviations and exodeviations. They are all attributed to either anomalies of the AC/A ratio or anomalies of the fusional convergence or divergence amplitudes. We report a case with pseudoconvergence insufficiency and another one with pseudoaccommodative convergence excess. In both cases, conv./div. excess and insufficiency were erroneously attributed to anomalies of the AC/A ratio or to anomalies of the fusional amplitudes. Our purpose is to show that numerous factors, other than anomalies in the AC/A ratio or anomalies in the fusional conv. or divergence amplitudes, can contaminate either the distance or the near deviations. This results in significant discrepancies between the distance and the near deviations despite a normal AC/A ratio and normal fusional amplitudes, leading to erroneous diagnoses and inappropriate treatment models.

    Pendrin (Slc26a4) is a Cl(-)/HCO3 (-) exchanger expressed in renal intercalated cells and mediates renal Cl(-) absorption. With pendrin gene ablation, blood pressure and vascular volume fall, which increases plasma renin concentration. However, serum aldosterone does not significantly increase in pendrin-null mice, suggesting that pendrin regulates adrenal zona glomerulosa aldosterone production. Therefore, we examined pendrin expression in the adrenal gland using PCR, immunoblots, and immunohistochemistry. Pendrin protein was detected in adrenal lysates from wild-type but not pendrin-null mice. However, immunohistochemistry and qPCR of microdissected adrenal zones showed that pendrin was expressed in the adrenal medulla, rather than in cortex. Within the adrenal medulla, pendrin localizes to both epinephrine- and norepinephrine-producing chromaffin cells. Therefore, we examined plasma catecholamine concentration and blood pressure in wild-type and pendrin-null mice under basal conditions and then after 5 and 20 min of immobilization stress. Under basal conditions, blood pressure was lower in the mutant than in the wild-type mice, although epinephrine and norepinephrine concentrations were similar. Catecholamine concentration and blood pressure increased markedly in both groups with stress. With 20 min of immobilization stress, epinephrine and norepinephrine concentrations increased more in pendrin-null than in wild-type mice, although stress produced a similar increase in blood pressure in both groups. We conclude that pendrin is expressed in the adrenal medulla, where it blunts stress-induced catecholamine release.

    Insufficient sleep poses an important and complicated set of health risks in the adolescent population. Not only is deficient sleep (defined as both sleep duration inadequate to meet sleep needs and sleep timing misaligned with the body's circadian rhythms) at epidemic levels in this population, but the contributing factors are both complex and numerous and there are a myriad of negative physical and mental health, safety and performance consequences. Causes of inadequate sleep identified in this population include internal biological processes such as the normal shift (delay) in circadian rhythm that occurs in association with puberty and a developmentally-based slowing of the "sleep drive", and external factors including extracurricular activities, excessive homework load, evening use of electronic media, caffeine intake and early school start times. Consequences range from inattentiveness, reduction in executive functioning and poor academic performance to increased risk of obesity and cardio-metabolic dysfunction, mood disturbances which include increased suicidal ideation, a higher risk of engaging in health risk behaviors such as alcohol and substance use, and increased rates of car crashes, occupational injuries and sports-related injuries. In response to these concerns, a number of promising measures have been proposed to reduce the burden of adolescent sleep loss, including healthy sleep education for students and families, and later school start times to allow adolescents to obtain sufficient and appropriately-timed sleep.

It was a double-blind, placebo-controlled, randomized, prospective study which lasted three months and with a dosage regime of 50-100 mg/day of AB. Fiftyfour patients completed the study (28 in AB and 24 in the placebo (P) groups, respectively). All patients were males, with a mean age or 65 +/- 6.1 years. In the study of pulmonary function only airway resistance (Raw) was changed, with a significant decrease at the third month in the AB group compared with the P group (0.83 +/- 0.31 vs. 1.07 +/- 0.46 kpa/L.S), with a p value of 0.05 (mean +/- SD) and PaO2 which improved from 8.15 +/- 0.88 to 8.81 +/- 2.3 kpa (61.17 +/- 6.6 to 66.10 +/- 10 mmHg), with a p value of 0.05.

    2016-04-01

    Exocrine pancreatic insufficiency (EPI) in diabetic patients is frequent. Studies based on fecal elastase-1 measurement give prevalence rates of 10‒30 % of severe and 22‒56 % of moderate EPI in type 1 and rates of 5‒46 % in type 2 diabetic patients. Nevertheless, not all patients report typical symptoms like diarrhea, steatorrhea and weight loss. For noninvasive testing the determination of fecal elastase-1 has the highest sensitivity and specificity. This test should be performed at least in all symptomatic patients. As differential diagnosis celiac disease (with a prevalence of about 3-5 % of type 1 diabetic patients), autonomic neuropathy, but also diseases like irritable bowel syndrome and gastrointestinal tumors have to be taken into account. Patients with symptoms and a fecal elastase-1 < 100 µg/g should be treated with pancreatic enzymes in adequate daily doses administered at main meals. Treatment improves symptoms significantly, supply with fat soluble vitamins is normalised, risk for osteoporosis is reduced. However, improvement of glucose metabolism has not been demonstrated consistently. A pancreatogenic diabetes, also termed as type 3c diabetes, has not necessarily to be treated with insulin, often-at least initially-treatment with oral antidiabetic drugs is sufficient.

    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: <1.00 D, moderate: 1.00 D to <3.00 D, and high: ≥3.00 D), presence/absence of clinical signs of CI and 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

    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.

    Fifty-eight patients with functional lesions of the adrenal glands underwent radiographic evaluation. Twenty-eight patients had primary aldosteronism (Conn syndrome), 20 had Cushing syndrome, and 10 had pheochromocytoma. Computed tomography (CT) correctly identified adrenal tumors in 11 (61%) of 18 patients with aldosteronomas, 6 of 6 patients with benign cortisol-producing adrenal tumors, and 5 (83%) of 6 patients with pheochromocytomas. No false-positive diagnoses were encountered among patients with adrenal adenomas. Bilateral adrenal hyperplasia appeared on CT scans as normal or prominent adrenal glands with a normal configuration; however, CT was not able to exclude the presence of small adenomas. Adrenal venous sampling was correct in each case, and reliably distinguished adrenal tumors from hyperplasia. Recurrent pheochromocytomas were the most difficult to loclize on CT due to the surgical changes in the region of the adrenals and the frequent extra-adrenal locations.

    Eighteen patients with unilateral non-metastatic non-functioning adrenal masses were studied with computed tomography (CT). Pathological examination in cases revealed benign adrenal adenomas. The others were followed up with serial CT scans and found to show no change in tumor size over a period of six months to three years. On the basis of these findings, the authors suggest certain criteria of a benign adrenal mass, including (a) diameter less than 5 cm, (b) smooth contour, (c) well-defined margin, and (d) no change in size on follow-up. Serial CT scanning can be used as an alternative to surgery in the management of many of these patients.

    Varicella zoster virus (VZV) becomes latent in ganglionic neurons derived from neural crest cells. Because the adrenal gland also contains medullary chromaffin cells of neural crest origin, we examined human adrenal glands and medullary chromaffin cell tumors (pheochromocytomas) for VZV and herpes simplex virus type 1 (HSV-1). We found VZV, but not HSV-1, DNA in 4/63 (6 %) normal adrenal glands. No VZV transcripts or antigens were detected in the 4 VZV DNA-positive samples. No VZV or HSV-1 DNA was found in 21 pheochromocytomas.

    Electron microscope examination of the adrenal cortex from three male human subjects revealed a special type of cell occurring in periendothelial spaces, in all adrenal cortex zones. It is a clear, spindle-shaped cell the principal cytoplasmic features of which are crystalline inclusions with a structure similar to that of the Reinke crystals of human testicular interstitial cells and an abundance of microfilaments. Enzymatic digestions with pronase, pepsin, and ribonuclease were performed, and no digestion of the crystals was obtained. The crystals had no peroxidase or acid phosphatase activities. This cell appears to be exclusive to human males and it may be related to adrenal androgen secretion. PMID:4347248

    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.

CAH due to 21-hydroxylase deficiency accounts for 95% of cases and shows a wide range of clinical severity. Glucocorticoid and mineralocorticoid replacement therapies are the mainstays of treatment of CAH. The optimal treatment for adults with CAH continues to be a challenge. Important long-term health issues for adults with CAH affect both men and women. These issues may either be due to the disease or to steroid treatment and may affect final height, fertility, cardiometabolic risk, bone metabolism, neuro-cognitive development and the quality-of-life. Patients with CAH should be regularly followed-up from childhood to adulthood by multidisciplinary teams who have knowledge of CAH. Optimal replacement therapy, close clinical and laboratory monitoring, early life-style interventions, early and regular fertility assessment and continuous psychological management are needed to improve outcome.

    Circadian secretion of steroid hormones by the adrenal cortex is required to maintain whole body homeostasis and to adequately respond to or anticipate environmental changes. The richly vascularized zona glomerulosa (ZG) cells in the pericapsular region regulate osmotic balance of body fluid by secreting mineralocorticoids responding to circulating bioactive substances, and more medially located zona fasciculata (ZF) cells regulate energy supply and consumption by secreting glucocorticoids under neuronal and hormonal regulation. The circadian clock regulates both steroidogenic pathways: the clock within the ZG regulates mineralocorticoid production via controlling rate-limiting synthetic enzymes, and the ZF secretes glucocorticoid hormones into the systemic circulation under the control of central clock in the suprachiasmatic nucleus. A functional biological clock at the systemic and cellular levels is therefore necessary for steroid synthesis and secretion.

    Capillary blood samples from 42930 infants born in the Italian region of Emilia-Romagna were collected for 17-hydroxyprogesterone radioimmunoassays on days 2, 3, 4, 5, 6, and 7, or between days 7 and 15 of life. A microfilter paper method modified from that of Pang et al.1 was used for this assay. Pathologic values of 17-hydroxyprogesterone were found in 5 infants giving an incidence in this homogeneous Caucasian population of 1:8586. We also investigated 17-hydroxyprogesterone values in relation to the day of sampling and the possible correlation between 17-hydroxyprogesterone values and birthweight and gestational age. We concluded that neonatal screening for congenital adrenal hyperplasia caused by 21-hydroxylase deficiency was possible by this method and that the infants' maturity and the particular day of collection of the samples affect the values but not the validity of the screening.

  2. Inflammatory mediators in mastitis and lactation insufficiency.

    Mastitis is a common inflammatory disease during lactation that causes reduced milk supply. 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.

    Genes that modulate the action of hormones and cytokines play a critical role in stress response, survival, and in growth and differentiation of cells. Many of these biological response modifiers are responsible for various pathological conditions, including inflammation, infection, cachexia, aging, genetic disorders, and cancer. We have previously identified a new gene, BRE, that is responsive to DNA damage and retinoic acid. Using multiple-tissue dot-blotting and Northern blotting, BRE was recently found to be strongly expressed in adrenal cortex and medulla, in testis, and in pancreas, whereas low expression was found in the thyroid, thymus, small intestine and stomach. In situ hybridization and immunohistochemical staining indicated that BRE was strongly expressed in the zona glomerulosa of the adrenal cortex, which synthesizes and secretes the mineralocorticoid hormones. It is also highly expressed in the glial and neuronal cells of the brain and in the round spermatids, Sertoli cells, and Leydig cells of the testis, all of which are associated with steroid hormones and/or TNF synthesis. However, BRE expression was downregulated in human adrenal adenoma and pheochromocytoma, whereas its expression was enhanced in abnormal adrenal tissues of rats chronically treated with nitrate or nitrite. These data, taken together, indicate that the expression of BRE is apparently associated with steroids and/or TNF production and the regulation of endocrine functions. BRE may play an important role in the endocrine and immune system, such as the cytokine-endocrine interaction of the adrenal gland.

    Immunohistochemical and behavioral techniques were used to study the effects of adrenal medulla grafts, implanted in striatum after bilateral kainic acid (KA) lesions of this structure, on the open field behavior of mice. KA-induced behavioral changes in leaning, grooming and locomotor activity of the open field test were significantly improved after grafting of the adrenal medulla, and in some respects, fully restored. Immunohistochemical identification showed that grafts contained neuron-like cells with a tyrosine hydroxylase (TH), phenylethanolamine N-methyltransferase, gamma-aminobutyric acid (GABA), choline acetyltransferase (ChAT), and enkephalin-like immunostainings. A likely interpretation of this complex pattern of results is that adrenal medullary grafts may restore the deficits of GABAergic neurons which in turn reverse the abnormalities in emotionality and locomotion. Neurobiologically, these behavioral improvements probably involve GABAergic and catecholaminergic factors of adrenal medulla grafts, although other neuroactive substances, such as acetylcholine and enkephalins, cannot be excluded.

  6. Palliative intensity modulated radiation therapy for symptomatic adrenal metastasis.

    Metastasis to the adrenal glands is quite common; especially from melanomas, breast, lung, renal and gastro-intestinal tumours. The most common tumour found in the adrenals in post mortem series is a metastatic tumour; incidence ranging from 13 to 27%. The diagnosis of adrenal metastasis is now more common and easier due to staging and subsequent follow up with Computed tomography /Magnetic resonance imaging and or positron emission tomography-computed tomography imaging studies. Most of the times these metastatic lesions are clinically occult and those that do have clinical symptoms complain of pain, nausea, vomiting and early satiety. We irradiated a patient of non small cell lung cancer with adrenal metastasis with palliative Intensity Modulated Radiation Therapy and achieved a good response in terms of pain relief, stable disease and no side effects of the treatment.

    We hypothesize that microgravity conditions during space flight alter the expression and specific activities of the adrenal medullary CA synthesizing enzymes (CASE). Previously, we examined adrenals from six rats flown for six days aboard STS 54 and reported that microgravity induced a decrease in the expression and specific activity of rat adrenal medullary tyrosine hydroxylase, the rate limiting enzyme of CA synthesis, without affecting the expression of other CASE. In the past, we analyzed some of the > 300 adrenals from two previous Space Shuttle missions (PARE 03 and SLS 2). The preliminary results (a) attest to the good state of tissue preservation, thus proving the feasibility of subsequent large-scale evaluation, and (b) confirm and extend our previous findings. With this grant we will be able to expeditiously analyze all our specimens and to complete our studies in a timely fashion.

  8. Nongenomic Actions of Adrenal Steroids in the Central Nervous System

    2015-01-01

    Mineralocorticoids and glucocorticoids are steroid hormones that are released by the adrenal cortex in response to stress and hydromineral imbalance. Historically, adrenocorticosteroid actions are attributed to effects on gene transcription. More recently, however, it has become clear that genome-independent pathways represent an important facet of adrenal steroid actions. These hormones exert nongenomic effects throughout the body, but a significant portion of their actions are specific to the central nervous system. These actions are mediated by a variety of signalling pathways, and lead to physiologically meaningful events in vitro and in vivo. Here we review nongenomic effects of adrenal steroids in the central nervous system at the levels of behaviour, neural system activity, individual neurone activity, and subcellular signalling activity. A clearer understanding of adrenal steroid activity in the central nervous system will lead to a better ability both to treat human disease, and to reduce side-effects of steroid treatments already in use.

    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

    We have noted an increasing number of cases of enlarged adrenal glands where the underlying diagnosis was masked by a diffusely hemorrhagic process. We identified from our database 59 cases (32 consults, 27 routine) of adrenal glands with diffuse (>25%) hemorrhage received between 2000 and 2014. Fifty-three adrenalectomies and 6 biopsies were identified. The diagnoses after central review were 41 adrenocortical adenomas, 1 nodular adrenocortical hyperplasia with associated myelolipoma, 1 benign adrenocortical cyst, and 10 nonneoplastic adrenal glands with hemorrhage. A definitive diagnosis for the 6 biopsies was precluded by the sample size. The adrenocortical adenomas (size, 1-13 cm; 25%-95% hemorrhage) showed clear cell change in the neoplastic area (10%-80% of the tumor), 19 showed focal calcification (1 with ossification), 11 showed areas of papillary endothelial hyperplasia, 10 showed scattered lymphoplasmacytic inflammation, 6 showed benign cortical tissue extending beyond the adrenal capsule into soft tissue, 1 showed necrosis in the form of ghost cells, 2 showed lipomatous change, and 6 were associated with incidental benign lesions (1 cortical cyst, 1 schwannoma, and 4 myelolipomas). Twenty-four of the adrenocortical adenomas were consults where the referring pathologist had trouble classifying the lesion. Of the 10 nonneoplastic adrenals (4.5-22 cm; 40%-80% hemorrhage), 2 were consults. In summary, pathologists have difficulties recognizing adrenocortical adenomas in the setting of a massively enlarged and hemorrhagic adrenal gland. Although there is a correlation between adrenocortical malignancy and size, hemorrhage into nonmalignant adrenal glands can result in markedly enlarged adrenals.

    An investigation is conducted to evaluate the response of the pituitary-adrenal system to a stress stimulus in the rat. In the investigation brain serotonin synthesis was inhibited with p-chlorophenylalanine. In other tests the concentration of serotonin was enhanced with precursors such as tryptophan or 5-hydroxytryptophan. On the basis of the results obtained in the study it is speculated that in some disease states there is a defect in serotonergic neuronal processes which impairs pituitary-adrenal feedback mechanisms.

    Large-scale medical sequencing provides a focal point around which to reorganize health care and health care research. Mobile health (mHealth) is also currently undergoing explosive growth and could be another innovation that will change the face of future health care. We are employing primary ovarian insufficiency (POI) as a model rare condition to explore the intersection of these potentials. As both sequencing capabilities and our ability to intepret this information improve, sequencing for medical purposes will play an increasing role in health care beyond basic research: it will help guide the delivery of care to patients. POI is a serious chronic disorder and syndrome characterized by hypergonadotrophic hypogonadism before the age of 40 years and most commonly presents with amenorrhea. It may have adverse health effects that become fully evident years after the initial diagnosis. The condition is most commonly viewed as one of infertility, however, it may also be associated with adverse long-term outcomes related to inadequate bone mineral density, increased risk of cardiovascular disease, adrenal insufficiency, hypothyroidism and, if pregnancy ensues, having a child with Fragile X Syndrome. There may also be adverse outcomes related to increased rates of anxiety and depression. POI is also a rare disease, and accordingly, presents special challenges. Too often advances in research are not effectively integrated into community care at the point of service for those with rare diseases. There is a need to connect community health providers in real time with investigators who have the requisite knowledge and expertise to help manage the rare disease and to conduct ongoing research. Here we review the pathophysiology and management of POI and propose the development of an international Clinical Research Integration Special Program (CRISP) for the condition. PMID:25288327

    2016-01-01

    The majority of benign adrenal cortex lesions leading to Cushing syndrome are associated to one or another abnormality of the cAMP/cGMP-phosphodiesterase signaling pathway. Phosphodiesterases (PDEs) are key regulatory enzymes of intracellular cAMP/cGMP levels. These second messengers play important regulatory roles in controlling steroidogenesis in the adrenal. Disruption of PDEs has been associated with a number of adrenal diseases. Specifically, genetic mutations have been associated with benign adrenal lesions, leading to Cushing syndrome and/or related adrenal hyperplasias. A Genome Wide Association study, in 2006, led to the identification of mutations in 2 PDE genes: PDE8B and PDE11A; mutations in these 2 genes modulate steroidogenesis. Further human studies have identified PDE2 as also directly regulating steroidogenesis. PDE2 decreases aldosterone production. This review focuses on the most recent knowledge we have gained on PDEs and their association with adrenal steroidogenesis and altered function, through analysis of patient cohorts and what we have learned from mouse studies.

    PubMed

    2013-01-01

    The adrenal gland, while small in size, provides a major punch to human metabolism. The interplay between the adrenal cortex hormones aldosterone and cortisol provides needed regulation to human metabolism. Aldosterone regulates the body sodium content affecting blood pressure thru fluid-volume regulation by the kidney. Cortisol, also from the adrenal cortex, contributes to regulation of glucose and protein metabolism. Diseases like addison's disease and Cushing's syndrome that affect the normal levels of these hormones can lead to serious pathologies that need to be detected thru clinical laboratory testing. The inner core of the adrenal gland, called the medulla, houses the catecholamine epinephrine, a fast acting neuropeptide hormone that can influence body action and energy levels quickly. The pheochromocytomas pathology of the adrenal medulla adversely affects the medulla hormones and needs to be recognized by clinical laboratory testing. The overview of the adrenal gland and its potential pathologies needs to be looked at anew in relation to post-traumatic stress disorder to find any linkage that may aid in the treatment and cure of our affected military soldiers. This interrelationship between cortisol and epinephrine in PTSD should be closely evaluated to determine if the suspected linkages are significant.

    In Type 1 and advanced Type 2 diabetes mellitus, elevation of plasma epinephrine plays a key role in normalizing plasma glucose during hypoglycaemia. However, recurrent hypoglycaemia blunts this elevation of plasma epinephrine. To determine whether recurrent hypoglycaemia affects peripheral components of the sympatho-adrenal system responsible for epinephrine release, male rats were administered subcutaneous insulin daily for 3 days. These recurrent hypoglycaemic animals showed a smaller elevation of plasma epinephrine than saline-injected controls when subjected to insulin-induced hypoglycaemia. Electrical stimulation of an adrenal branch of the splanchnic nerve in recurrent hypoglycaemic animals elicited less release of epinephrine and norepinephrine than in controls, without a change in adrenal catecholamine content. Responsiveness of isolated, perfused adrenal glands to acetylcholine and other acetylcholine receptor agonists was also unchanged. These results indicate that recurrent hypoglycaemia compromised the efficacy with which peripheral neuronal activity stimulates adrenal catecholamine release and demonstrate that peripheral components of the sympatho-adrenal system were directly affected by recurrent hypoglycaemia.

    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. 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.

    The diagnosis and management of adrenal diseases hinge upon accurate determination of hormone concentrations in blood and other body fluids. The advent of immunoassays for various steroid hormones has enabled the remarkable progress in adrenal disease over the last several decades, with some limitation. Sequential immunoassay of single analytes is a tedious process, which requires aliquots for each assay. In many complex adrenal diseases, including adrenal cancer and congenital adrenal hyperplasia, the patterns or ratios of multiple steroids rather than the value of any one steroid is more relevant. Although gas chromatography/mass spectrometry of urinary steroid metabolites has been employed to profile steroid production, throughput is slow, and availability is sparse. Recent generations of liquid chromatography-tandem mass spectrometry instruments (LC-MS/MS) provide the throughput and sensitivity required to measure many steroids simultaneously using small samples for commercial and research uses. Even in the best hands, however, LC-MS/MS suffers from limitations and requires diligent attention to detail during method development and implementation. This article reviews the theory, instrumentation principles and terminology, and practical application of mass spectrometry to clinical adrenal disorders.

  20. The Interplay between Estrogen and Fetal Adrenal Cortex

    PubMed Central

    Kaludjerovic, Jovana; Ward, Wendy E.

    2012-01-01

    Estrogen is a steroid hormone that regulates embryogenesis, cell proliferation and differentiation, organogenesis, the timing of parturition, and fetal imprinting by carrying chemical messages from glands to cells within tissues or organs in the body. During development, placenta is the primary source of estrogen production but estrogen can only be produced if the fetus or the mother supplies dehydroepiandrosterone (DHEA), the estrogen prohormone. Studies show that the fetal zone of the fetal adrenal cortex supplies 60% of DHEA for placental estrogen production, and that placental estrogen in turn modulates the morphological and functional development of the fetal adrenal cortex. As such, in developed countries where humans are exposed daily to environmental estrogens, there is concern that the development of fetal adrenal cortex, and in turn, placental estrogen production may be disrupted. This paper discusses fetal adrenal gland development, how endogenous estrogen regulates the structure and function of the fetal adrenal cortex, and highlights the potential role that early life exposure to environmental estrogens may have on the development and endocrinology of the fetal adrenal cortex.
