MicroRNA(miR)-200b-3p has been associated with many tumors,but its involvement in pituitary adenoma is unclear.This study investigated the molecular mechanism underlying miR-200b-3p regulation in pituitary adenomas to provide a theoretical basis for treatment.Bioinformatics was used to analyze pituitary adenoma-related genes and screen new targets related to RECK and miRNA.As well,the relationship between miR-200b-3p and RECK protein was verified using a double-luciferase reporter gene assay.The expression of miR-200b-3p in clinical samples was analyzed by in situ hybridization.Transfection of the miR-200b-3p inhibitor and small interfering-RECK(si-RECK)was verified by qPCR.GH3 cell viability and proliferation were detected using CCK8 and EdU assays.Apoptosis was detected by flow cytometry and western blotting.Wound healing and Transwell assays were used to detect cell migration and invasion.The effects of miR-200b-3p and RECK on GH3 cells were verified using salvage experiments.miR-200b-3p was highly expressed in pituitary tumor tissue.Inhibitors of miR-200b-3p inhibited cell proliferation promoted cell apoptosis,inhibited invasion and migration,and inhibited the expression of matrix metalloproteinases.Interestingly,miR-200b-3p negatively regulated RECK.The expression of RECK in pituitary adenoma tissues was lower than that in neighboring tissues.Si-RECK rescued the function of miR-200b-3p inhibitors in the above cellular behaviors,and miR-200b-3p accelerated the development of pituitary adenoma by negatively regulating RECK expression.In summary,this study investigated the molecular mechanism by which miR-200b-3p regulates the progression of pituitary adenoma through the negative regulation of RECK.The findings provide a new target for the treatment of pituitary adenoma. 展开更多

BACKGROUND Pituitary gland metastasis is an unusual event,and pituitary metastasis from lung adenocarcinoma is extremely rare and associated with poor prognosis.To date,approximately 15 cases have been reported.CASE SUMMARY Here,we present the case of a 64-year-old woman with pituitary metastasis derived from lung adenocarcinoma,which was difficult to distinguish from other sellar tumors.The patient presented to the neurosurgery clinic with blurred vision and intermittent headache.During hospitalization,brain computed tomography(CT)and magnetic resonance imaging revealed a pituitary macroadenoma.Chest CT revealed irregular nodules in the basal segment of the lower lobe of the left lung,which were likely lung cancer.Positron emission tomography-CT revealed a carbohydrate metabolism tumor in the lungs and sellar region,which was considered malignant.Postoperative pathological examination of the sellar tumor revealed lung adenocarcinoma.CONCLUSION Excision of pituitary metastases combined with radiotherapy and chemotherapy should be a priority treatment for patients with pituitary metastasis. 展开更多

BACKGROUND Pituitary stalk interruption syndrome(PSIS)is a rare anatomical defect of the pituitary gland falling under the spectrum of holoprosencephaly phenotypes.It is characterized by a deficiency in anterior pituitary hormones,such as growth hormone,gonadotropins,and thyroid hormones.Due to the syndrome's rarity and nonspecific manifestations,there is a lack of standardized treatment strategies.Consequently,early diagnosis through imaging and on-time intervention are crucial for improving patients’outcomes.CASE SUMMARY A 30-year-old man presented with absent secondary sexual characteristics and azoospermia.Laboratory evaluation revealed a deficiency in gonadotropins,while thyroid function was mostly within normal ranges.Magnetic resonance imaging of the pituitary gland showed pituitary stalk agenesis,hypoplasia of the anterior pituitary,and ectopic posterior pituitary,leading to the diagnosis of PSIS.Initially,the patient underwent 6 mo of gonadotropin therapy without significant changes in hormone levels and secondary sexual characteristics.Pulsatile gonadotropin-releasing hormone therapy was then administered,resulting in the detection of sperm in the semen analysis within 3 mo.After 6 mo,routine semen tests showed normal semen quality.The couple faced challenges in conceiving due to abstinence and underwent three cycles of artificial insemination,which was unsuccessful.They also attempted in vitro fertilization,but unfortunately,the woman experienced a miscarriage 10 wk after the embryo transfer.CONCLUSION Early detection,accurate diagnosis,and timely treatment are crucial in improving the quality of life and fertility of PSIS patients. 展开更多

BACKGROUND The neuroendoscopic approach has the advantages of a clear operative field,convenient tumor removal,and less damage,and is the development direction of modern neurosurgery.At present,transnasal surgery for sphenoidal pituitary tumor is widely used.But it has been found in clinical practice that some patients with this type of surgery may experience post-operative nausea and vomiting and other discomforts.AIM To explore the effect of reserved gastric tube application in the neuroendoscopic endonasal resection of pituitary tumors.METHODS A total of 60 patients who underwent pituitary adenoma resection via the endoscopic endonasal approach were selected and randomly divided into the experimental and control groups,with 30 in each group.Experimental group:After anesthesia,a gastric tube was placed through the mouth under direct vision using a visual laryngoscope,and the fluid accumulated in the oropharynx was suctioned intermittently with low negative pressure throughout the whole process after nasal disinfection,during the operation,and when the patient recovered from anesthesia.Control group:Given the routine intraoperative care,no gastric tube was left.The number of cases of nausea/vomiting/aspiration within 24 h post-operation was counted and compared between the two groups;the scores of pharyngalgia after waking up,6 h post-operation,and 24 h postoperation.The frequency of postoperative cerebrospinal fluid leakage and intracranial infection were compared.The hospitalization days of the two groups were statistically compared.RESULTS The times of postoperative nausea and vomiting in the experimental group were lower than that in the control group,and the difference in the incidence of nausea was statistically significant(P<0.05).After the patient woke up,the scores of sore throat 6 h after the operation and 24 h after operation were lower than those in the control group,and the difference was statistically significant(P<0.05).The number of cases of postoperative cerebrospinal fluid leakage and intracranial infection was higher than that of the control group,but there was no statistically significant difference from the control group(P>0.05).The hospitalization days of the experimental group was lower than that of the control group,and the difference was statistically significant(P<0.05).CONCLUSION Reserving a gastric tube in the endoscopic endonasal resection of pituitary tumors,combined with intraoperative and postoperative gastrointestinal decompression,can effectively reduce the incidence of nausea,reduce the number of vomiting and aspiration in patients,and reduce the complications of sore throat The incidence rate shortened the hospitalization days of the patients. 展开更多

BACKGROUND Neuroendocrine tumors(NET)are rare heterogeneous tumors that arise from neuroendocrine cells throughout the body.Acromegaly,a rare and slowly progressive disorder,usually results from a growth hormone(GH)-secreting pituitary adenoma.CASE SUMMARY We herein describe a 38-year-old patient who was initially diagnosed with diabetes.During colonoscopy,two bulges were identified and subsequently removed through endoscopic submucosal dissection.Following the surgical intervention,the excised tissue samples were examined and confirmed to be grade 2 NET.^(18)F-ALF-NOTATATE positron emission tomography-computed tomography(PET/CT)and 68Ga-DOTANOC PET/CT revealed metastases in the peri-intestinal lymph nodes,prompting laparoscopic low anterior resection with total mesorectal excision.The patient later returned to the hospital because of hyperglycemia and was found to have facial changes,namely a larger nose,thicker lips,and mandibular prognathism.Laboratory tests and magnetic resonance imaging(MRI)suggested a GH-secreting pituitary adenoma.The pituitary adenoma shrunk after treatment with octreotide and was neuroendoscopically resected via a trans-sphenoidal approach.Whole-exome sequencing analysis revealed no genetic abnormalities.The patient recovered well with no evidence of recurrence during follow-up.CONCLUSION ^(18)F-ALF-NOTATE PET/CT and MRI with pathological analysis can effectively diagnose rare cases of pituitary adenomas complicated with rectal NET. 展开更多

Introduction: in adults, adenomas are the most frequent causes of pituitary tumours. The objective was to characterize its epidemiological and clinical aspects, as well as its therapeutic modalities in Senegal. Methodology: this was a multicenter, retrospective, descriptive and analytical study carried out from the Senegalese register of pituitary adenomas (2008-2022). Results: 242 patients were collected with an average age of 42.4 ± 13 years and a sex ratio (M/F) of 0.91. The mean consultation time was 19.7 ± 23 months. The circumstances of discovery were pituitary apoplexy (11 cases, 4.54%), tumor syndrome (176 cases, 72.72%), gonadal manifestations (103 cases, 42.56%), dysmorphic syndrome (21 cases, 8.68%), hypercorticism (15 cases, 6.19%). Morphologically, it was a macroadenoma (197 cases, 81.40%), an extensive adenoma (22 cases, 9.10%). The hormonal profile was lactotropic hypersecretion (80 cases, 33.05%), somatotropic (13 cases, 5.39%), corticotropic (14 cases, 5.78%), mixed (9 cases, 3.71%). The factors significantly associated with prolactinoma were young age (p = 0.000), female sex (p = 0.000), long consultation delay (p = 0.000) and microadenoma (p = 0.001). Only arterial hypertension was associated with acromegaly (p = 0.000). We found a significant correlation between Cushing’s disease and microadenomas (p = 0.000). Non-secreting adenomas were significantly associated with advanced age (p = 0.000), long delay in consultation (p = 0.000), male gender (p = 0.000), tumor syndrome (p = 0.001) and macroadenomas (p = 0.000). Pituitary surgery was effective in 173 patients (71.49%) including 166 cases (68.59%) by transphenoidal approach. Postoperative incidents were transient diabetes insipidus in 82 cases (47.39%), cerebrospinal fluid leak (20 cases, 11.56%). Death was observed in 18 patients in the entire series (7.44%). The latter had a tumor syndrome (88.88%), a macroadenoma (83.33%) and had undergone pituitary surgery (72.22%). Conclusion: pituitary pathology has become a reality with clinical and secretory polymorphism. The diagnostic delay explains the predominance of macroadenomas which are sources of pre and post-operative complications. 展开更多

Introduction: In the context of pituitary adenoma, bacterial meningitis is a possible complication of surgical or medical treatment. The occurrence of meningitis before any treatment is exceptional, explained by the existence of an osteomeningeal breach caused by the adenoma whose main symptom is rhinorrhea. Case Report: We report a case of bacterial meningitis complicating a prolactin pituitary macroadenoma. The patient had been referred for jet vomiting in a febrile context preceded by headaches and visual blurring. There was no rhinorrhea. The examination revealed a meningeal syndrome and the diagnosis of acute bacterial meningitis was made. The isolated germ was the pneumococcus. Faced with headaches and visual blurring, a cerebral scan revealed a pituitary macroadenoma and pituitary hormone dosage had shown hyperprolactinemia. The meningitis was sterilized and the prolactinoma was treated with dopaminergic agonists. This allowed the normalization of prolactinemia and the disappearance of symptoms. Conclusion: The pituitary adenoma was complicated by bacterial meningitis without treatment and the presence of a meningeal breach. Hormonal and bacterial treatments have been successful. 展开更多

Objective: To study the relationship between histopathology and clinical prognosis of invasive pituitary adenoma subjected to transsphenoidal surgery. Methods: The enrolled were 82 patients with invasive pituitary adenomas undergoing transsphenoidal surgery during Jan. 2000 - May 2003 in our department with full MR imaging findings, pathology data and follow-up information. The follow-up duration was 5-30 months. Results: MR imaging findings of invasive pituitary adenoma included: depression of the sellar floor, involvement of sphenoid sinus and cavernous sinus, breakthrough of diaphragma sellae, encasement of internal carotid artery, etc. Pathological examination revealed that the invasion rate of dura in sella turcica was the highest among the structures around tumor. Pituitary adenoma apoplexy was found in 20 cases (24.4%). The total removal rate for PRL-secreting adenomas was significantly lower than that for non-secreting adenomas (P<0.01), but non-, GH-, ACTH-secreting adenomas had no significant differences. The recurrence rate of PRL-secreting adenomas was higher than that of non- and GH-secreting adenomas (P<0.05). Conclusion: Among invasive pituitary adenomas, the therapeutic effects of non-and GH-secreting pituitary adenomas are better than that of PRL-secreting adenomas. Invasive biological behaviors of invasive pituitary adenomas result in radical operation failure and postoperative recurrence. 展开更多

BACKGROUND As research on diabetes continues to advance,more complex classifications of this disease have emerged,revealing the existence of special types of diabetes,and many of these patients are prone to misdiagnosis and underdiagnosis,leading to treatment delays and increased health care costs.The purpose of this study was to identify four causes of secondary diabetes.CASE SUMMARY Secondary diabetes can be caused by various factors,some of which are often overlooked.These factors include genetic defects,autoimmune disorders,and diabetes induced by tumours.This paper describes four types of secondary diabetes caused by Williams–Beuren syndrome,Prader–Willi syndrome,pituitary adenoma,and IgG4-related diseases.These cases deviate significantly from the typical progression of the disease due to their low incidence and rarity,often leading to their neglect in clinical practice.In comparison to regular diabetes patients,the four individuals described here exhibited distinct characteristics.Standard hypoglycaemic treatments failed to effectively control the disease.Subsequently,a series of examinations and follow-up history confirmed the diagnosis and underlying cause of diabetes.Upon addressing the primary condition,such as excising a pituitary adenoma,providing glucocorticoid supplementation,and implementing symptomatic treatments,all patients experienced a considerable decrease in blood glucose levels,which were subsequently maintained within a stable range.Furthermore,other accompanying symptoms improved.CONCLUSION Rare diseases causing secondary diabetes are often not considered in the diag-nosis of diabetes.Therefore,it is crucial to conduct genetic tests,antibody detection and other appropriate diagnostic measures when necessary to facilitate early diagnosis and intervention through proactive and efficient management of the underlying condition,ultimately improving patient outcomes. 展开更多

Objective: To explore the pituitary function of acute pituitary apoplexy and its effect by transsphenoidal surgery. Methods: The clinical data and endocrine hormones level of 25 patients with acute pituitary apoplexy who underwent transsphenoidal surgery from Jan. 2002 to June 2004 were retrospectively analyzed. Results: 13 cases underwent surgery within 3 days after admission and 22 cases within 1 week. Of the 25 cases, 9 patients suffered the impairment of pituitary-thyroidal function, 14 cases of pituitary-adrenal function and 11 cases of pituitary-gonadal function before surgery. After surgery, 5/9, 8/14 and 7/11 were recovered from the corresponding hypopituitarism. Conclusion: Hypopituitarism is a major manifestation of acute pituitary apoplexy. Urgent surgery decompression contributed to the improvement of pituitary function. Patients with hypopituitarism after surgery required the corresponding hormones replacement therapy. 展开更多
