Patients with Ectopic Posterior Pituitary: Report of Six Cases

WOS:000627743000006Objective: Ectopic posterior pituitary (EPP) can occur because of a migration defect or neurodegeneration of the hypothalamic nuclei. EPP is typically rarely diagnosed. Therefore, we aimed to report our patients with EPP. Material and Methods: This is a retrospective study (approved by the Ege University Ethical Committee, protocol 20-7T/49) that included 6 patients with EPP who were followed up between 2012 and 2019. We collected information on age, sex, height, weight, body mass index, age at the diagnosis, history of traumatic delivery, consanguinity, multiple hormone deficiency and treatment. We examined laboratory levels and medical records, and, magnetic resonance imaging (MRI) reports. Results: The mean age of patients was 25.83 years, and the age at diagnosis was 11.16 years. One patient was female, and the others were male. They were receiving hormone replacement treatment. The patients were diagnosed with EPP during their childhood. All patients, except 2, were taking growth hormone replacement therapy. Only one patient had a history of consanguinity. Additional information about the patients is described in the patient sections. Conclusion: Patients with EPP are rarely seen, and this rare condition should be considered when a patient has panhypopituitarism. MRI is the gold standard imaging modality for hypophysis to identify this condition. in addition, patients who have EPP in MRI should be screened for hypopituitarism

Subclinical Hypothyroidism Increases the Requirement of Renal Replacement Therapy After Cardiac Surgery

WOS:000557211400008PubMed: 32726204Background: Subclinical or biochemically diagnosed hypothyroidism (SCH) is defined as an elevated serum thyroid-stimulating hormone (TSH) with normal free thyroxine (FT4) levels. Thyroid hormones play a major role in the normal function of the heart and vascular physiology. Atherosclerosis, increased systemic vascular resistance, and decreased arterial compliance are common pathophysiological changes that may occur in hypothyroidism. Acute kidney injury (AKI) is one of the devastating complications after cardiac surgery. Age, diabetes mellitus (DM), preexisting renal dysfunction, hypertension, impaired left ventricular function, and severe arteriosclerosis are the major risk factors for the development of AKI. The purpose of the current study was to analyze the influence of SCH on AM and the requirement of renal replacement therapy (RRT) after isolated coronary artery bypass graft surgery (CABG). Methods: We retrospectively reviewed the prospectively collected data of 336 adult patients who underwent isolated CABG surgery with normal renal function (baseline serum creatinine value <1.4 mg/dL) from January 2017 to January 2019. The patients were divided into two groups either having the diagnosis of SCH (Group I, N = 47) or not (Group II, N = 289). SCH was diagnosed based on preoperative serum TSH and FT4 levels. Kidney injury was interpreted, according to RIFLE classification. The effect of SCH on AM and the need for RRT after CABG was determined using logistic regression analysis and the results were expressed as odds ratio (OR) with a 95% confidence interval (CI). A P value < .05 was considered statistically significant. Results: Subclinical hypothyroidism was diagnosed in 14% of all patients. Postoperative AKI occurred in 15 patients (31.9%) in Group I, whereas there were 42 patients (14.5%) in Group II. On logistic regression analysis, the presence of SCH was shown to be associated with an increased incidence of postoperative AKI (OR, 0.363; 95% CI, 0.181-0.727; P = .004). RRT was used in 2.97% of patients (seven patients in Group I and three patients in Group II, P < .001). The 30-day mortality was 2.1%. Conclusion: The presence of SCH seems to be associated with an increased incidence of AKI and increased requirement for RRT after cardiac surgery

Plurihormonal hipofizer dev makroadenomu olan olgu sunumu

We would like to draw the attention of the readers to Pit-1 positive giant macroadenomas in this work. A 62-year-old male patient was admitted to the hospital due to his vision loss and blurred vision in the left eye. His pituitary magnetic resonance imaging revealed the presence of a diffuse and homogeneous mass lesion originating from the pituitary gland having grade 4 invasion into the bilateral cavernous sinus and eroding the base of the sella. He consulted our department before his operation in 2016. Laboratory examination revealed that pituitary hormone levels were within normal ranges while the testosterone level [total testosterone 0.27 ng/mL (2.8-8)] was low. Pathological findings revealed a pituitary adenoma that displayed focal immunoreactivity to thyrotrophin, growth hormone, and prolactin. While the main prevalence and the basic mechanism of plurihormonal pituitary adenomas are not clear, one of the hypotheses is based on the role of divergent transcription factors such as Pit-1. According to this condition, we should perform a complete biochemical and histologic evaluation in patients with pituitary adenomas

Could Retroperitoneal Ganglioneuroma be a Dopamine Secreting Ganglioneuroma?

WOS: 000435845900008Ganglioneuromas are rarely occurring benign tumors characterized by hyperplasia of mature ganglia and satellite cells. They are well-differentiated, slow growing, and autonomous nervous system neoplasms, which are usually asymptomatic and do not release any hormones. A male patient aged 26 years was evaluated for secondary hypertension six months ago. Ultrasonography of the abdomen revealed a mass lesion around the right kidney. An analysis of the 24-hour urine sample of the patient revealed the following parameters: 5-HIAA=3.9 mg/day (2-7), metanephrine=56.3 mu g/day (52-341), and normetanephrine=146.1 mu g/day (88-444). The computed tomography scan of the abdomen showed a retroperitoneal mass of 10 cm in size, containing minute calcified foci in the right retroperitoneal region. The mass was excised through general surgery and was classified as ganglioneuroma. The blood pressure of the patient returned to normal level after surgery, and he needed no further antihypertensive treatment. Besides, the metanephrine and normetanephrine levels in the 24-hour urine were also observed to be normal as in the preoperative period. Retroperitoneal masses can actually be ganglioneuromas and an accurate diagnosis can be achieved only through postoperative histopathological evaluation. After the operation, blood pressure of the patient returned to normal. This suggests that retroperitoneal ganglioneuroma could possibly secrete dopamine, epinephrine, or norepinephrine

Two challenging cases of pituicytoma

Introduction Pituicytoma is a rare tumor of the pituitary gland derived from neurohypophyseal pituicytes. Case 1 A 58-year-old female presented with decreased vision; she was admitted to the neurosurgery department of Ege University after the detection of a pituitary macroadenoma. Magnetic resonance imaging (MRI) showed a 28 * 18 * 17-mm suprasellar mass, and laboratory tests revealed hypopituitarism. Hydrocortisone and L-thyroxine treatment were initiated, and the patient underwent resection through the endoscopic endonasal approach (EEA). The histopathological examination revealed a pituicytoma. The recurrence of tumor was detected during the 1-year follow-up, and the patient is awaiting surgery. Case 2 A 70-year-old woman presented with visual changes; she had a past medical history of hypophyseal macroadenoma and pituicytoma resected through an EEA in 2012 and 2017, respectively. During follow-up, 2 years after the second surgery, MRI showed progression of the pituicytoma then measuring 38 x 23 x 22 mm; it had invaded the cavernous sinus and was causing hydrocephaly and panhypopituitarism. The patient underwent the third resection through the transcranial approach in order to minimize bleeding. After this surgery, the patient developed diabetes insipidus and underwent treatment with desmopressin. Histopathological examination revealed a pituicytoma. At 6-month follow-up, imaging showed a sellar suprasellar mass 37 x 22 x 24 mm invading the cavernous sinus, indicative of recurrence. In the postoperative period, the patient applied to the department of radiation oncology to have fractionated radiotherapy. Discussion Pituicytomas are known to be low-grade tumors; because of their rarity, they are a real challenge. These patients should be followed up closely
