Adrenal glands

RATIONALE: Gitelman syndrome (GS), also known as familial hypokalemia and hypomagnesemia, is a rare autosomal recessive inherited disease caused by primary renal desalinization caused by impaired reabsorption of sodium and chloride ions in the distal renal tubules. We report a case of clinical and genetic characteristics of GS accompanied with Graves disease and adrenocorticotrophic hormone (ACTH)-independent adrenocortical adenoma. PATIENT CONCERNS: The patient is a 45 year old female, was admitted to our hospital, due to a left adrenal gland occupying lesion as the chief complaint...

The effects of the administration of the opioid agonist, morphine, on plasma and tissue concentrations of Met-enkephalin were determined in 14 wk old female chickens. In addition, effects of morphine on proenkephalin (PENK) expression were examined. Plasma concentrations of Met-enkephalin were reduced 10 minutes after morphine administration. Plasma concentrations of peptides that contain Met-enkephalin motifs were decreased 30 minutes after morphine administration. Tissue concentrations of Met-enkephalin tended to be depressed following morphine administration...

An 82-year-old man had been treated for lung adenocarcinoma and hepatocellular carcinoma (HCC). Contrast-enhanced computed tomography examination showed swelling of the left adrenal gland, suggesting metastasis of lung adenocarcinoma, HCC, or primary adrenal tumor. Endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) was performed for the pathological diagnosis, and adrenal metastasis of HCC was diagnosed. No notable complications due to EUS-FNA were found. There have been reports of adrenal metastasis due to various cancers, but there are few reports that can confirm the diagnosis of adrenal metastasis of HCC using EUS-FNA...

Primary aldosteronism (PA) is the most common form of secondary hypertension. Accurate subtyping of PA is essential to identify unilateral disease, as adrenalectomy improves outcomes. Subtyping PA requires adrenal vein sampling (AVS), which is technically challenging and results from AVS may not always be conclusive. We present a case of a 37-year-old man with PA whose AVS studies were inconclusive due to apparent bilateral aldosterone suppression (ABAS). As a result, our patient was misdiagnosed as having bilateral PA and medically managed until a repeat AVS showed lateralization to the right adrenal gland...

Catecholamine surge and haemodynamic derangements are normally expected during the surgery for pheochromocytoma and benign functioning adrenal tumours. This male patient in his 50s underwent radical nephrectomy for renal cell carcinoma. The patient had no comorbidities. Three hours into the surgery, during electrocauterisation of the upper pole of the kidney, the patient's blood pressure unexpectedly spiked to 180/110 mm Hg, which was immediately followed by a decrease in heart rate to 35-38 beats/min...

OBJECTIVE: To report the survival times in dogs diagnosed with adrenal tumors with vascular or soft tissue invasion that did not undergo adrenalectomy. ANIMALS: Retrospective case series of 32 client-owned dogs. METHODS: The medical records of a referral veterinary hospital were reviewed to identify dogs that were diagnosed with an invasive adrenal mass and did not undergo adrenalectomy between January 2013 and December 2022. Data collected included signalment, examination findings, and diagnostic results from the initial presentation...

X-linked adrenoleukodystrophy (X-ALD) is a rare genetic disorder caused by pathogenic variants in the ABCD1 gene. The symptoms include primary adrenal insufficiency (PAI), progressive spinal cord disease, inflammatory demyelinating cerebral disease, and primary hypogonadism. It is exceptionally rare that pediatric PAI is accompanied by central precocious puberty (CPP). The purpose of this study was to better understand the diversity of clinical manifestations of X-ALD and to identify the ABCD1 gene mutation in a case of a boy with X-ALD accompanied by CPP...

BACKGROUND: Although uncommon, adrenal hemorrhage has multiple etiologies. Because clinical characteristics, management, and outcomes of patients with adrenal hemorrhage are inadequately described, we examined the underlying etiology, need for intervention, evolution of imaging characteristics, and adequacy of subsequent evaluation. METHODS: We performed a retrospective review of patients diagnosed with adrenal hemorrhage (radiologist-confirmed density consistent with hemorrhage on computed tomography) from 2005 to 2021 at a university-based institution...

BACKGROUND: Nocardia farcinica is one of the most common Nocardia species causing human infections. It is an opportunistic pathogen that often infects people with compromised immune systems. It could invade human body through respiratory tract or skin wounds, cause local infection, and affect other organs via hematogenous dissemination. However, N. farcinica-caused bacteremia is uncommon. In this study, we report a case of bacteremia caused by N. farcinica in China. CASE PRESENTATION: An 80-year-old woman was admitted to Peking Union Medical College Hospital with recurrent fever, right abdominal pain for one and a half month, and right adrenal gland occupation...

This study investigated the impact of neonatal exposure to endocrine-active compounds (EACs): flutamide (antiandrogen), 4-tert-octylphenol (an estrogenic compound), and methoxychlor (an organochlorine insecticide exhibiting estrogenic, antiestrogenic and antiandrogenic activities) on androgen production within porcine adrenal glands. The expression of genes related to androgen synthesis and the level of androgen production were analyzed (i) in the adrenal glands of piglets exposed to EACs during the first 10 days of life (in vivo study), and (ii) in adrenal explants from sow-fed or formula-fed 10-day-old piglets incubated with EACs (ex vivo study)...

BACKGROUND AND AIMS: Congenital adrenal hyperplasia (CAH) is a group of disorders that affect the production of steroids in the adrenal gland and are inherited in an autosomal recessive pattern. The clinical and biochemical manifestations of the disorder are diverse, ranging from varying degrees of anomalies of the external genitalia to life-threatening adrenal insufficiency. This multicenter study aimed to determine the demographics, biochemical, clinical, and genetic characteristics besides the current status of adult patients with CAH nationwide...

Gastric diverticula are a rare phenomenon that is typically asymptomatic and encountered incidentally. Due to the relative proximity between the gastric diverticula and the left adrenal gland, they may mimic adrenal masses on computed tomography (CT). For this reason, the preferred diagnostic methods for gastric diverticula are upper gastrointestinal series or direct visualization on endoscopy. The present report describes an unusual case of a gastric diverticulum mimicking an abscess of the adrenal gland with the apparent spread of infection to the left lower lobe of the lung...

Paragangliomas (PGLs) are tumors that are rarely malignant; the majority of them are benign. Similar to pheochromocytoma, they develop from the autonomic nerve system. This system originates from neural crest cells and can undergo neoplastic transformation. PGLs can arise either inside or outside the adrenal glands. Head and neck PGLs are very scarce. The primary locations where this tumor commonly originates within this region are the carotid body, jugular bulb, and vagal body. Hence, in our case report, we attempt to highlight the uncommon presentation of this disease in a 46-year-old female, who initially presented with hypertension and persistent dysphonia...

Many cancers, including glioblastoma (GBM), have a male-biased sex difference in incidence and outcome. The underlying reasons for this sex bias are unclear but likely involve differences in tumor cell state and immune response. This effect is further amplified by sex hormones, including androgens, which have been shown to inhibit anti-tumor T cell immunity. Here, we show that androgens drive anti-tumor immunity in brain tumors, in contrast to its effect in other tumor types. Upon castration, tumor growth was accelerated with attenuated T cell function in GBM and brain tumor models, but the opposite was observed when tumors were located outside the brain...

OBJECTIVE: Glucocorticoid resistance is a rare endocrine disease caused by variants of the NR3C1 gene encoding the glucocorticoid receptor (GR). We identified a novel heterozygous variant (GRR569Q) in a patient with uncommon reversible glucocorticoid resistance syndrome. METHODS: We performed ex vivo functional characterization of the variant in patient fibroblasts and in vitro through transient transfection in undifferentiated HEK 293T cells to assess transcriptional activity, affinity, and nuclear translocation...

OBJECTIVE: Patients with congenital adrenal hyperplasia (CAH) require life-long glucocorticoid replacement, including stress dosing (SD). This study prospectively assessed adrenal crisis (AC) incidence, frequency, and details of SD and disease knowledge in adult and paediatric patients and their parents. DESIGN: Prospective, observational study. METHODS: Data on AC and SD were collected via a patient diary. In case of AC, medical records were reviewed and patient interviews conducted...

Objective: To analyze the clinical features of patients with metastatic pheochromocytoma/paraganglioma (PPGL). Methods: A follow-up study. The clinical data of 250 patients with metastatic PPGL treated at Peking Union Medical College Hospital from January 2018 to August 2023 were retrospectively analyzed, including 124 males and 126 females. The clinical features and treatment status of patients with metastatic PPGL were summarized and analyzed. Kaplan-Meier survival curve was used to evaluate patients' prognosis...

BACKGROUND 21-hydroxylase deficiency, an essential enzyme for glucocorticoid and mineralocorticoid synthesis, is the cause of congenital adrenal hyperplasia (CAH) in more than 95% of cases. It is an autosomal recessive disorder encoded by the CYP21A2 gene, categorized into classical forms, which encompass the salt-wasting (SW) and simple virilizing (SV) forms, as well as the nonclassical form (NC). The aim of medical treatment is to replace missing glucocorticoids and, if necessary, mineralocorticoids, while also reducing elevated adrenal androgens...
