When was acromegaly discovered

Acromegaly and pituitary adenomas are not passed down in families. Acromegaly can take years to develop. Changes can be so subtle that by the time you are diagnosed, you may have had the condition for some time.

Often, people seek care for headaches or vision problems that arise as the tumor grows. People with acromegaly often develop other medical conditions, such as:.

Acromegaly can be challenging to diagnose. People turn to OHSU for our expert diagnosis and experience with this condition. We know you want quick answers, so we often complete your tests and appointment in one day.

Surgery to remove the tumor is often the first step. You also may need medication and radiation therapy. Your care team will work with you to develop a treatment plan that best meets your needs.

This approach is now an accepted best practice. Long-term monitoring is also important. The hormonal imbalance caused by acromegaly can put you at risk for heart problems, colon growths and other conditions.

In addition to producing too much GH, tumors can press on the pituitary gland or an optic nerve. This can affect your vision, cause headaches or affect hormone production. It can lead to symptoms such as weight gain and sexual problems. If your surgeon can remove the tumor completely, you may not need any other treatments. Expertise: Our neurosurgeons remove more than tumors in and around the pituitary gland each year.

As a result, we have a high level of skill and experience. Studies show that high volume of cases leads to better results for patients. Minimally invasive surgery: We often use a minimally invasive technique called transsphenoidal surgery to remove the tumor through the nose. This precise approach leaves no noticeable scars and has fewer side effects and risks.

Most patients go home two days after surgery. We will work with you to find the right medication and dose, and to manage any side effects. Expertise: We played a central role in designing and running clinical studies that resulted in FDA approval for pasireotide and mifepristone, medications for acromegaly and Cushing disease. Some patients have an aggressive type of acromegaly, with high GH levels persisting after treatment.

In these cases, we may recommend radiation therapy. Depending on your needs, you may have traditional radiation therapy or a type called stereotactic radiosurgery. Precise procedure: We use the most advanced equipment available for stereotactic radiosurgery. The Novalis Tx radiosurgery system provides a detailed view of the tumor.

It enables our team to deliver targeted radiation beams to the tumor while protecting healthy tissue. Patients typically have a series of treatments, with small doses over four to six weeks.

His perioperative period was uneventful. Pathological evaluation showed the resected pituitary adenoma to be focally reactive for prolactin and GH, and was negative for adrenocorticotropic hormone, thyroid-stimulating hormone, follicle-stimulating hormone, and luteinizing hormone. Serum laboratory tests performed 3 weeks postoperatively showed normalization of his prolactin, IGF-1, and GH levels Table 1.

Acromegaly is a rare disorder with clinical manifestations that are primarily attributed to the systemic effect of sustained hypersecretion of GH. Complications associated with this disorder include cardiovascular dysfunction, respiratory compromise, malignancies, metabolic derangements, skeletal abnormalities, rheumatologic arthropathies, and neuropathies [ 5 ]. With these wide arrays of associated complications, it is not surprising that acromegaly carries increased morbidity and mortality.

Some reports indicate a twofold to threefold increase in mortality when compared with the general population, with cardiovascular events accounting for the majority of mortality [ 6 ]. Other notable causes of death include respiratory complications and malignancies [ 7 ]. Therefore, it is imperative that clinicians from all specialties maintain a high index of suspicion on patients presenting with specific symptoms who have characteristic dysmorphic features of acromegaly.

Patients with acromegaly present an unusual challenge to anesthesiologists in the perioperative period. Multiple studies have documented a higher incidence of difficult intubation than in patients without acromegaly [ 9 ], with preoperative Mallampati III or IV identified as one of the predictive factors for difficult intubation [ 9 , 10 ]. Mask ventilation is often difficult because of the dysmorphic facial anatomy in these patients.

As a consequence of macroglossia, laryngeal mucosal and cartilage hypertrophy [ 11 ], visualization of vocal cords during direct laryngoscopy is often limited. Even when the vocal cords are visible, they may be hypertrophic, causing narrowed glottic opening and increased resistance to passage of endotracheal tube. With the rare opportunity of performing a thorough airway examination preoperatively and during laryngoscopy, anesthesiologists can therefore play a key role in early diagnosis of acromegaly, as was done in this patient.

It is also imperative that a history of difficult intubations needs to be ascertained. Early detection will help circumvent not only the potential airway mishaps in subsequent surgeries in patients with undiagnosed acromegaly through proper planning but also help mitigate associated comorbidities that decrease quality of life and increase mortality.

When diagnosed, a pituitary adenoma is the primary cause of acromegaly. Depending on tumor size, peripheral visual disturbances may accompany the systemic manifestation of the disorder. Surgery, specifically transsphenoidal adenectomy, appears to be the mainstay therapeutic modality for most patients.

Following diagnosis and institution of appropriate treatment, it is also imperative that a comprehensive workup of all organ systems involved with this disorder be pursued. In summary, acromegaly can often remain undiagnosed until late in the disease process. Late diagnosis is due, in part, to the presence of nonspecific signs and symptoms such as hypertension, diabetes, headache, obstructive sleep apnea , as well as slow progression of the characteristic features associated with the disease.

Primary care physicians during routine visits and anesthesia personnel during preoperative evaluation should be cognizant of the clinical presentation of this disease. If not for a high index of suspicion of the disease, as observed in this case during a routine surgical procedure, it could remain undiagnosed until tumor resection becomes high risk leading to increased morbidity and mortality.
