While benign adrenal tumors are routinely incidentally discovered by imaging, not all these tumors have pathological effects, existing as nonfunctional adrenal tumors (NFAT). However, others overproduce steroids resulting in mild autonomous cortisol secretion (MACS) or Cushingâs syndrome (CS) if severe.
CHI Memorial Medical Group announces the opening of CHI Memorial Endocrinology Associates, a practice that provides comprehensive medical management and care for conditions like type 1 and 2 diabetes, thyroid disease, thyroid cancer and a range of metabolic, pituitary and adrenal disorders. The practice will be led by Prashanth Sekhar, MD, a fellowship train […]
Among 174 patients with Cushing's Syndrome included in the longitudinal cohort study (pituitary in 106, ectopic in 25, adrenal in 43), median baseline HbA1c was 6.9%. Of these, 41 patients were not on any therapy for hyperglycemia, 93 (52%) took oral medications, and 64 (37%) were on insulin.
Brittle hair is one of the symptoms of Cushingâs syndrome, which is a rare condition caused by excess cortisol, the main hormone body stress. But, there are many other, more obvious symptoms of Cushingâs syndrome, including high blood pressure, fatigue, and back pain. Treatment for Cushingâs syndrome may involve changing the dose of medication that may be ca […]
Neuroendocrine pulmonary tumors in people with Cushing syndrome (CS) are associated with increased nodal metastasis, higher recurrence, and lower disease-free survival compared with quiescent bronchopulmonary tumors, according to results from an observational case series published in JAMA Network Open. Researchers said their study shows these tumors are not […]
Hi there, I (22F, 140 pounds) just got the results from my 24 hr ufc and was hoping someone could take a look at them for me and possibly clear some things up as it'll be a while until I see my endocrinologist. I know that hypoglycemia is not typical of Cushing's, I was actually looking into adrenal insufficiencyâŚ
I'm going to try to keep all of my post-op BLA updates in this thread. I am hoping it will eventually show positive progression and be a realistic and inspirational thread for others. Today I am two weeks post-op BLA. So far, no scares. I am on 30/20/20 of hydrocortisone and weaning by 10 mg every four days. I am sleeping a good bit during the day and r […]
However, children that experience low cortisol concentrations and symptoms of cortisol insufficiency can take advantage using a modified release hydrocortisone formulation. The acute adrenal crisis is a life-threatening condition in all ages, treatment is effective if administered promptly, and it must not be delayed for any reason.
Adrenal insufficiency (AI) is a life-threatening disorder, with increased morbidity and mortality, especially in case of an acute illness that can increase the requirement of cortisol. A novel infectious disease, termed Coronavirus Disease 2019 (COVID-19), appeared in 2020.
Ectopic Cushingâs syndrome due to ectopic ACTH&CRH-secreting by pheochromocytoma is extremely rare and can be fatal if not properly diagnosed. It remains unclear whether a unique cell type is responsible for multiple hormones secreting.
This is a fun opportunity for the rare disease community in each region and state to get together before Rare Disease Week to foster community and camaraderie.

[t]he degree of change in exposure of mifepristone when co-administered with strong CYP3A inhibitors is unknownâ and âmay present a safety risk.â The concern was that without the required study the patients with Cushingâs syndrome that take strong inhibitors may be unable to use mifepristone.
During the first few days of September 2007, Lori had surgery to remove her adrenal gland. She experienced extreme difficulty post surgery and never recovered.
As many as 1 in 10 people have a non-cancerous tumor on one or both of their adrenal glands that could cause the gland to produce excess amounts of the stress hormone cortisol.

Data from LINC3 and LINC4 provide insight into the impact of dosing titration schedules on risk of hypocortisolism-related adverse events associated with osilodrostat use in patients with Cushing’s disease.
Data from a pair of phase 3 studies presented at the American Academy of Clinical Endocrinologyâs 30th Annual Meeting (AACE 2021) is providing insight into the effect of dose titration schedules with use of osilodrostat (Isturisa) in patients with Cushingâs disease.
Presented by Maria Fleseriu, MD, of Oregon Health and Science University, the analysis of the LINC3 and LINC4 demonstrated the more gradual titration occurring in LINC4 resulted in a lower proportion of hypocortisolism-related adverse events, suggesting up-titration every 3 weeks rather than every 2 weeks could help lower event risk without compromising mean urinary free cortisol (mUFC) control.
âFor patients with Cushingâs disease, osilodrostat should be initiated at the recommended starting dose with incremental dose increases, based on individual response/tolerability aimed at normalizing cortisol levels,â concluded investigators.
With approval from the US Food and Drug Administration in March 2020 for patients not eligible for pituitary surgery or have undergone the surgery but still have the disease, osilodrostat became the first FDA-approved therapy address cortisol overproduction by blocking 11β-hydroxylase. Based on results of LINC3, data from the trial, and the subsequent LINC4 trial, provide the greatest available insight into use of the agent in this patient population.
The study presented at AACE 2021 sought to assess whether slow dose up titration might affect rates of hypocortisolism-related adverse events by comparing titration schedules from both phase 3 trials. Median osilodrostat exposure was 75 (IQR, 48-117) weeks and 70 (IQR, 49-87) weeks in LINC3 and LINC4, respectively. The median time to first mUFC equal to or less than ULN was 41 (IQR, 30-42) days in LINC3 and 35 (IQR, 34-52) days in LINC4.
Adverse events potentially related to hypocortisolism were more common among patients in LINC3 (51%, n=70) than LINC4 (27%, n=20). Upon analysis of adverse events, investigators found the most commonly reported type of adverse event was adrenal insufficiency, which included events of glucocorticoid deficiency, adrenocortical insufficiency, steroid withdrawal syndrome, and decreased urinary free cortisol.
Results incited the majority of hypocortisolism-related adverse events occurred during the dos titration periods of each trial. In LINC3, 54 of the 70 (77%) hypocortisolism-related adverse events occurred by week 26. In comparison, 58% of hypocortisolism-related adverse events occurring in LINC4 occurred prior to week 12. Investigators noted most of events that occurred were mild or moderate and managed with dose interruption or reduction of osilodrostat or concomitant medications.
The UCSF website in an obituary from Kate Vidinsky reads âHe took a particular interest in pituitary disorders, those affecting the pea-sized âmaster glandâ at the base of the brain responsible for controlling the bodyâs hormone levels. He was a pioneer of transsphenoidal surgery â the endonasal approach for removing pituitary tumors â and performed more than 3,300 of these procedures at UCSF Medical Center.”
The New York Times in an obituary published yesterday described him as âa pioneering and virtuosic San Francisco neurosurgeonâ.

A 63-year-old man was referred to the Massachusetts General Hospital Neuroendocrine & Pituitary Tumor Clinical Center for management of a pituitary macroadenoma. He experienced increasingly severe retro-orbital headaches in the past year. He reported no double vision, fatigue, orthostatic dizziness, change in beard growth or reduction in libido. An outside head CT scan showed an enlarged pituitary gland.
Imaging and laboratory tests
A pituitary MRI with magnified pituitary slices and gadolinium contrast was ordered. A well-circumscribed âsnowman-shapedâ sellar mass was identified, measuring 2.6 cm x 2 cm x 1.8 cm (anteroposterior x transverse x craniocaudal) with suprasellar extension (Figure 1). The lesion was heterogeneous on T1-weighted scans after enhancement with IV gadolinium contrast. An area of hypointensity in the superior margin was consistent with a small area of cystic or hemorrhagic degeneration.
Although the mass did not extend laterally into the cavernous sinus, the sellar mass extended upward into the suprasellar cistern through a hole in the dural, the diaphragma sellae, to compress the optic chiasm. The restriction of adenoma growth by the diaphragma sellae results in the snowman shape of the macroadenoma. The optic chiasm and infundibulum (pituitary stalk) could not be identified on coronal or sagittal images (Figure 1). Visual field on confrontation suggested lateral field deficits (bilateral lateral hemianopsia) that were confirmed on formal Goldmann kinetic perimetry visual fields.

A small hypodense area in the adenoma likely represented hemorrhage/cystic degeneration (yellow arrow). The tumor does not surround the carotid siphon, an S-shaped portion of the internal carotid artery (red arrows) within the cavernous sinus located laterally from the sella turcica where the pituitary gland resides.

Initial hormonal evaluation was normal and included morning adrenocorticotropic hormone 18 pg/mL, cortisol 13.64 Âľg/dL, thyroid-stimulating hormone 2.14 uIU/mL, free thyroxine 1.2 ng/dL and prolactin 12.6 ng/mL. The patientâs morning testosterone level was normal at 324 ng/dL, with follicle-stimulating hormone 2.4 mIU/mL and luteinizing hormone 1.6 mIU/mL. His insulin-like growth factor I level was normal at 124 ng/mL.
Tumor resection
The patient was treated preoperatively with stress-dose hydrocortisone 50 mg. He then underwent transsphenoidal pituitary tumor resection. After the surgeon believed there was an adequate excision of the tumor, the extent of tumor resection was confirmed by an intraoperative MRI (Figure 2 on page 8).
Figure 2. Intraoperative MRI scan. The large macroadenoma is not seen after transsphenoidal surgery. The optic chiasm (yellow arrow) can be seen after removal of the tumor. (A) Coronal image. (B) Sagittal image. Abbreviation: SS = spenoid sinus.
The operation was concluded after the imaging confirmed the complete resection of the pituitary adenoma. The patientâs postoperative course was uneventful. Imaging 4 weeks after the resection confirmed complete resection of the suprasellar mass with residual enhancement of the resection bed and sphenoid sinuses (Figure 3 on page 8). The postoperative MRI revealed a normal optical chiasm and a downward tending of the infundibulum to the residual pituitary gland located inferiorly along the sella turcica (pituitary fossa) of the sphenoid bone. Pathology confirmed a pituitary adenoma. His anterior and posterior pituitary function were normal 6 weeks postoperatively, and his visual field deficit improved.
Intraoperative MRI
Imaging like that used in this case occurs in a specially designed operating room that allows MRI scans during surgery without moving the patient from the surgical table. The MRI is kept in a shielded enclosure during the procedure and then moved along a track into the operating room for imaging. Clinical indications for the use of intraoperative MRI in neurosurgery include resection of pituitary macroadenomas. In the past, these tumors underwent transsphenoidal resection, and the postoperative MRI was performed after 1 or more days after the procedure to check for complete removal. If residual tumor was found, the patients underwent watchful waiting, external radiation or repeat surgery.
The strategic advantage of an intraoperative MRI is that the imaging is performed during the operative procedure, and if there is any residual tumor, surgery can be resumed after the MRI is moved back into the shielded enclosure.

The optic chiasm and infundibulum (pituitary stalk) can be seen after resection of the tumor. The pituitary stalk is deviated to the left of the sella where the residual normal thyroid is locate along the sella turcica. The floor of the sella enhances with gadolinium infusion after surgery due to postoperative inflammation. (A) Coronal image. (B) Sagittal image. Abbreviation: SS = spenoid sinus.
It has been reported that the use of intraoperative MRI does not increase complication rates compared with conventional transsphenoidal surgery. Reports on the improvement of gross tumor resection using intraoperative MRI are variable, perhaps due to the expertise of the surgeon. Several reports suggest the use of intraoperative MRI allowed additional resection of noninvasive macroadenomas in 67% to 83% of the patients with a gross tumor resection. These results suggest that a substantial volume reduction and increased gross tumor resection of pituitary macroadenomas occurs with the use of intraoperative MRI compared with standard surgery. One study demonstrated that the gross tumor resection rates of invasive tumors was also improved with the use of intraoperative MRI compared with usual preoperative imaging and surgery (25% vs. 7%).
The use of intraoperative MRI, especially with transsphenoidal reoperations for invasive and noninvasive pituitary macroadenomas, leads to significantly higher âgross tumor resectionâ rates. This method prevents additional operations or treatment, such as radiation, because it reduces the number of patients with residual adenoma after surgery. This technology is usually found in specialized tertiary care hospitals but should be considered for reoperation for large pituitary macroadenomas or initial operation for large invasive pituitary macroadenomas.

Ed started as Senior Staff Fellow in the Surgical Neurology Branch at the NIH (1981). After 5 years, Ed would become the Chief of the Surgical Neurology Branch. He would stay on as Branch Chief and lead the neurosurgical effort at the NIH for the next 21 years. During his tenure, he developed clinical, research, and training programs in epilepsy, congenital malformations, syringomyelia, nervous system neoplasia, drug delivery, and vascular malformations. The strength of these programs was his leadership and their multidisciplinary nature, which incorporated physicians and scientists across the basic, translational, and clinical arenas. Research investigation was always targeted at defined clinical problems. Under his direction, these programs shaped understanding of the studied neurological disorders, as well as improving patient care.
Please let us know your experiences with this new program!
Hallmark Health and Tufts Medical Center have established a new neurosurgery program at Melrose-Wakefield Hospital to bring advanced care and services to the community. Fellowship-trained neurosurgeon Mina G. Safain, MD, has been jointly hired by Hallmark Health and Tufts Medical Center to lead the new program. He will provide care at both Melrose-Wakefield Hospital and Tufts Medical Center.
The neurosurgery program is an example of clinical integration of services between Hallmark Health and Tufts Medical Center since Hallmark Health joined Wellforce as a third founding member this past January. At that time, leaders from the organizations discussed finding ways to bring specialized care traditionally performed at academic medical centers into the community hospital setting for the benefit and convenience of patients.
âOffering neurosurgery provides a service for our patients that few community hospitals can offer,â said Steven Sbardella, MD, chief medical officer at Hallmark Health. âOur clinical relationship with Tufts Medical Center enables us to bring more highly specialized care options to our patients.â
âWe are extremely excited to work with the physicians at Melrose-Wakefield Hospital and look forward to increasing the services available to care for patients with neurologic diseases,â said Carl Heilman, MD, neurosurgeon-in-chief at Tufts Medical Center. âDr. Safain is an exceptionally talented and compassionate neurosurgeon and the perfect person to spearhead the launch of this new program.â
Dr. Safainâs clinical interests include all diseases affecting the brain, spine and peripheral nervous system. He has specific interests in minimal access procedures for degenerative, infectious and oncologic spine disorders, as well as minimally invasive treatments for brain tumors, including neuro-endoscopy.
âThe opportunity to practice in the community is very important to me,â said Dr. Safain. âI look forward to working with the esteemed staff and providers at Melrose-Wakefield Hospital and Lawrence Memorial Hospital and treating the patients in the surrounding communities.â
âWelcoming such a highly-respected neurosurgeon as Mina Safain to our team is a tremendous benefit for our communities and patients across our system including Lawrence Memorial Hospital in Medford and Melrose-Wakefield Hospital,â said Dr. Sbardella.
Dr. Safain, together with Ran Ku, PA, a neurosurgery physician assistant with more than 12 years of experience, will provide neurosurgery coverage and expertise five days a week.
Dr. Safain received his medical degree from Yale University School of Medicine. He completed his neurosurgery residency at Tufts Medical Center serving as chief resident during his final year. Dr. Safain also completed fellowship training in pituitary and neuro-endoscopic surgery at Brigham and Womenâs Hospital.
Dr. Safain has published and presented nationally on a range of topics related to neurosurgical diseases and minimally invasive treatments for brain tumors.
