Review
CONTEXT
Salt and water homeostasis is regulated hormonally, so polyuria can result from endocrine disease directly or via secondary effects. These mechanisms are not consistently considered in primary care management of nocturia.
OBJECTIVE
To conduct a systematic review (SR) of nocturia in endocrine disease and reach expert consensus for primary care management.
EVIDENCE ACQUISITION
Four databases were searched from January 2000 to April 2020. A total of 4382 titles and abstracts were screened, 36 studies underwent full-text screening, and 14 studies were included in the analysis. Expert and public consensus was achieved using the nominal group technique (NGT).
EVIDENCE SYNTHESIS
Twelve studies focused on mechanisms of nocturia, while two evaluated treatment options; none of the studies took place in a primary care setting. NGT consensus identified key clinical evaluation themes, including the presence of thirst, a medical background of diabetes mellitus or insipidus, thyroid disease, oestrogen status, medications (fluid loss or xerostomia), and general examination including body mass index. Proposed investigations include a bladder diary, renal and thyroid function, calcium, and glycated haemoglobin. Morning urine osmolarity should be examined in the context of polyuria of >2.5 l/24 h persisting despite fluid advice, with urine concentration >600 mOsm/l after fluid restriction excluding diabetes insipidus. Treatment should involve education, including adjustment of lifestyle and medication where possible. Any underlying endocrine disorder should be managed according to local guidance. Referral to endocrinology is needed if there is hyperthyroidism, hyperparathyroidism, or morning urine osmolarity <600 mOsm/l after overnight fluid avoidance.
CONCLUSIONS
Endocrine disease can result in nocturia via varied salt and water regulation pathways. The aim of management is to identify and treat causative factors, but secondary effects can restrict improvements in nocturia.
PATIENT SUMMARY
People with altered hormone function can suffer from severe sleep disturbance because of a need to pass urine caused by problems in controlling water and salt levels. An expert panel recommended the best ways to assess and treat these problems on the basis of the rather small amount of up-to-date published research available.

Review
In 2017, the World Health Organization established that pituicytoma, granular cell tumor (GCT), spindle cell oncocytoma (SCO) and sellar ependymomas (SE) are posterior pituitary tumors (PPT). They probably arise from the pituicytes and may constitute a unique histopathological entity. We carried out a systematic review using PubMed's database. A total of 266 patients with pathological diagnosis of PPT (135 pituicytomas, 69 GCT, 47 SCO, 8 SE and 7 mixed histology tumors) were analyzed. Gender distribution was identical and median age at diagnosis was 48 ± 21.8 years. Main presentation symptoms were visual disorders (n = 142; 58.1%), headache (n = 99; 40.5%), hypopituitarism (n = 84; 34.4%), hypercortisolism (n = 10; 4.1%), polyuriapolydipsia (n = 6; 2.4%) and acromegaly features (n = 5; 2.0%). On MRI, 122 (47.6%) patients showed sellar with suprasellar extension masses, 67 (23.1%) were suprasellar and 63 (24.6%) exclusively sellar. Median tumor size was 22.0 ± 14.2 mm. Two hundred sixty four patients underwent surgery, transphenoidal access was selected in 132 (64.4%) and craniotomy in 58 (28.3%). Complications were hypopituitarism (n = 70; 42.1%), diabetes insipidus (n = 55; 33.1%) and hemorrhage (n = 50; 30.1%). Tumor persisted in 93 patients (45.6%) and recurred in 13 (6.4%). Regarding comparison between main types of PPT, SCO patients were diagnosed later (60.0 vs 47.0 vs 47.0 years, p = 0.023), the tumor was larger 25.0 mm [10.8] vs 20.0 mm [14.2] vs 2.0 mm [15.0] and they were frequently sellar with suprasellar extension tumors (71.7% vs 46.2% vs 32.8%, p = 0.003) compared to pituicytoma and GCT. In conclusion, PPT are rare tumors and have been misdiagnosed mainly as non-functioning pituitary adenomas. Different types of PPT share similar epidemiology, clinical manifestations and surgical outcomes. Surgery is the only curative option but complications and subtotal resection are common.

Review
Erdheim-Chester disease (ECD) is a rare form of non-Langerhans-cell histiocytosis, associated in more than 50% of cases to BRAF(V600E) mutations in early multipotent myelomonocytic precursors or in tissue-resident histiocytes. It encompasses a spectrum of disorders ranging from asymptomatic bone lesions to multisystemic, life-threatening variants. We reviewed all published reports of histologically-confirmed ECD and explored clinical, radiological, prognostic and therapeutic characteristics in a population of 448 patients, including a unique patient from our Department. To find a clinically relevant signature defining differentiated prognostic profiles, the patients' disease features were compared in relation to their CNS involvement that occurred in 56% of the entire population. Diabetes insipidus, visual disturbances, pyramidal and extra-pyramidal syndromes were the most recurrent neurological signs, whereas concomitant pituitary involvement, retro-orbital masses and axial lesions in the presence of symmetric bilateral osteosclerosis of long bones depicted the typical ECD clinical picture. Patients with CNS infiltration showed a lower occurrence of heart involvement and a higher incidence of bone, skin, retro-peritoneal, lung, aortic and renal infiltration. No difference in the therapeutic algorithm was found after stratification for CNS involvement. A better understanding of the disease pathogenesis, including BRAF deregulation, in keeping with improved prognostic criteria, will provide novel suggestions for the management of ECD.

Review
Sodium and water perturbations, manifesting as hyponatraemia and hypernatraemia, are common in patients who had an acute stroke, and are associated with worse outcomes and increased mortality. Other non-stroke-related causes of sodium and water perturbations in these patients include underlying comorbidities and concomitant medications. Additionally, hospitalised patients who had an acute stroke may receive excessive intravenous hypotonic solutions, have poor fluid intake due to impaired neurocognition and consciousness, may develop sepsis or are administered drugs (eg, mannitol); factors that can further alter serum sodium levels. Sodium and water perturbations can also be exacerbated by the development of endocrine consequences after an acute stroke, including secondary adrenal insufficiency, syndrome of inappropriate antidiuretic hormone secretion and diabetes insipidus. Recently, COVID-19 infection has been reported to increase the risk of development of sodium and water perturbations that may further worsen the outcomes of patients who had an acute stroke. Because there are currently no accepted consensus guidelines on the management of sodium and water perturbations in patients who had an acute stroke, we conducted a systematic review of the literature published in English and in peer-reviewed journals between January 2000 and December 2020, according to PRISMA guidelines, to assess on the current knowledge and clinical practices of this condition. In this review, we discuss the signs and symptoms of hyponatraemia and hypernatraemia, the pathogenesis of hyponatraemia and hypernatraemia, their clinical relevance, and we provide our recommendations for effective treatment strategies for the neurologist in the management of sodium and water perturbations in commonly encountered aetiologies of patients who had an acute stroke.

Meta-Analysis Review
PURPOSE
Hypopituitarism is a possible complication of the surgical treatment of acromegaly. However, there is a wide variability in the incidence rates of surgery-induced hypopituitarism. The purpose of this study was the systematic collection and synthesis of information on the incidence rates of hypopituitarism, panhypopituitarism, specific axis deficiencies and diabetes insipidus after surgery for acromegaly treatment.
METHODS
We systematically reviewed all the papers that have reported pituitary deficits after surgery for acromegaly published up until December 2014, in the PubMed database. We identified 92 studies enrolling 6988 patients. A meta-analysis was performed to evaluate the incidence rates. We also performed several subgroup analyses to evaluate the impact of both surgical technique, and treatment prior to surgery, on the results.
RESULTS
The weighted incidence rates were 12.79 % for hypopituitarism (95 % CI 9.88-16.00 %), 2.50 % for panhypopituitarism (95 % CI 1.24-4.15 %), 6.50 % for ACTH deficiency (95 % CI 4.07-9.44 %), 4.39 % for TSH deficiency (95 % CI 2.99-6.04 %), 6.70 % for FSH/LH deficiency (95 % CI 3.89-10.17 %), 14.95 % for GH deficiency (95 % CI 7.25-24.64 %), 10.05 % for transient (95 % CI 7.18-13.33 %) and 2.42 % for permanent diabetes insipidus (95 % CI 1.70-3.27 %).
CONCLUSION
Our study provides new data on the incidence rates of hypopituitarism, specific pituitary axis deficiencies and diabetes insipidus after surgical treatment of acromegaly. Somatotroph function appears to be more prone to deficit than the other axes. However, there is a high heterogeneity between studies and several factors may influence the incidence of hypopituitarism.

Review
BACKGROUND
The ability to preoperatively predict postoperative complication risks is valuable for individual counseling and (post)operative planning, e.g. to select low-risk patients eligible for short stay surgery or those with higher risks requiring special attention. These risks however, are not well established in pituitary surgery.
METHODS
We conducted a systematic review of associations between preoperative characteristics and postoperative complications of endoscopic transsphenoidal surgery according to the PRISMA guidelines. Risk of bias was assessed through the QUIPS tool.
RESULTS
In total 23 articles were included, containing 5491 patients (96% pituitary adenoma). There was a wide variety regarding the nature and number of risk factors, definitions, measurement and statistics employed, and overall quality of mainly retrospective studies was low. Consistent significant associations were older age for complications in general, and intraventricular extension for cerebrospinal fluid (CSF) leaks. Associations identified in some but not all studies were younger age, increased BMI, female gender, and learning curve for CSF leaks; increased tumor size for complications in general; and Rathke's cleft cysts for diabetes insipidus. Mortality (incidence rate 1%) was not addressed as a risk factor.
CONCLUSION
Based on current literature, of low to medium quality, it is not possible to comprehensively quantify risk factors for complications. Nevertheless, older age and intraventricular extension were associated with increased postoperative complications. Future research should aim at prospective data collection, reporting of outcomes, and uniformity of definitions. Only then a proper risk analysis can be performed for endoscopic pituitary surgery.

OBJECTIVE
Pituitary surgery is a frequent neurosurgical procedure for the management of pituitary adenomas, but little research has been done on the impact of healthcare disparities on surgical results. Healthcare inequity/disparity in terms of race and socioeconomic status (SES), in addition to age and gender, was evaluated in this study to see if they affect the results of pituitary surgery.
METHODS
A systematic literature search was carried out utilizing the MEDLINE (PubMed), Web of Science, Scopus, and Embase electronic databases from conception to 2023. The Newcastle-Ottawa Scale was used for quality assessment of the included studies.
RESULTS
Twenty-one studies yielded a total of 381,643 patients, and removal of the studies with temporal overlap resulted in 134,832 patients with a mean ± SD age of 51.52 ± 0.41 years. Based on the available data, 46.63% of patients were male. Black patients were more likely to be recommended against surgery, while Asian or Pacific Islander patients were more likely to be recommended for surgery. Postoperative course and outcome showed mixed results, with some studies reporting higher rates of transient diabetes insipidus and stroke in racial minority populations. Private hospitals admitted more White patients, and certain racial groups had reduced access to high-volume centers. SES disparities were assessed in terms of insurance and income. Patients with government insurance or without insurance were more likely to be recommended active surveillance instead of definitive treatment. Furthermore, high SES was associated with a higher likelihood of receiving surgical treatment, better treatment outcomes, and better access to high-volume centers. In terms of age and gender disparity, older patients and females were less likely to be recommended for surgical treatment. Age and gender did not consistently impact postoperative course and treatment outcomes, with varying results across studies. No significant age and gender disparities were observed in hospital admissions and charges.
CONCLUSIONS
This study revealed the presence of disparities in pituitary adenoma surgery based on race, SES, age, and gender. These disparities highlight the need for further research and interventions to ensure equitable access to appropriate surgical treatment and improved outcomes for all patients with pituitary adenomas.

Review
Background: Volatile anesthetics were used as sedative agents in COVID-19 (Coronavirus Disease 2019) invasively ventilated patients for their potentially beneficial pharmacological effects and due to the temporary shortages of intravenous agents during the pandemic crisis. Methods: Online databases (PubMed, EMBASE, The Cochrane Central Register of Controlled Trial) and the “clinicaltrials.gov” website were searched for studies reporting the use of isoflurane, sevoflurane or desflurane. Results: We identified three manuscripts describing the beneficial effects of isoflurane on 41 COVID-19 patients with acute respiratory distress syndrome (ARDS) in Germany (n = 2) and in the USA (n = 1), in terms of reduction in the use of opioids and other sedatives. We also found a case report of two patients with transient nephrogenic diabetes insipidus, which started after 6 and 8 days of sevoflurane sedation. We identified two randomized controlled trials (RCTs; 92 patients overall), two observational studies (238 patients) on the use of volatile anesthetics in COVID-19 patients that were completed but not yet published, and one RCT interrupted for a low recruitment ratio (19 patients) and thus not published. We also identified five ongoing RCTs on the use of inhaled sedation in ARDS, which are also likely to be recruiting COVID-19 patients and which have currently enrolled a total of >1643 patients. Conclusion: Isoflurane was the most frequently used volatile agent in COVID-19 patients and allowed a reduction in the use of other sedative and analgesic drugs. Randomized evidence is building up and will be useful to confirm or challenge these findings.

Review
INTRODUCTION
The endonasal endoscopic approach (EEA) for the resection of tuberculum sellae meningiomas (TSMs) has, more recently, been advocated as an alternative approach to deal with this challenging tumor. The aim of this study was to conduct a systematic review of publications of TSMs excised through the transsphenoidal route in the past 10 years and review data on the extent of excision, visual outcomes and complication rates.
EVIDENCE ACQUISITION
We performed a thorough systematic review of the medical literature following the PRISMA guidelines. A medical librarian retrieved a list of 3443 articles published from 2006-2015 from the MEDLINE, EMBASE and Cochrane Central databases. Two of the authors independently screened for titles and abstracts and excluded 3340 of them. We reviewed the full text of the remaining 103 articles and included in our analysis 12 that met the following inclusion criteria: 1) 5 or more cases reported; 2) the extent of resection, visual outcomes and complication rates that were specifically documented for TSMs excised through the transsphenoidal route.
EVIDENCE SYNTHESIS
Twelve studies that included 150 patients were analyzed. The mean age was 55 years. The mean tumor volume, reported in 2 studies, was 6.6 cc and mean maximum diameter, reported in 11 studies, was 25 mm. The gross total resection rate was 77.2%. Vision improved in 79.5% of cases and deteriorated in 7.3%. CSF leak postoperatively occurred in 15.3% of patients. In the 11 studies that reported hormonal outcomes, there was a 9.4% transient hyponatremia or diabetes insipidus and 2.2% of patients developed a new permanent endocrine dysfunction. A symptomatic vascular injury was reported in 2.6% of patients. There was one mortality (0.6%).
CONCLUSIONS
The endonasal endoscopic transsphenoidal excision of TSMs is a feasible, safe and effective surgical option with a low morbidity and mortality. The use of this approach has evolved in the last 10 years and in some centers has replaced the transcranial route for selected cases. Given the limited availability and heterogeneity of comparative observational studies, a direct comparison with transcranial approaches was not performed for the purpose of this review analysis. Likewise, from an epidemiological and statistical perspective a meta-analysis was deemed inappropriate.

PURPOSE
Acute Sheehan's syndrome is a rare, but potentially life-threatening, obstetric event that can be complicated by diabetes insipidus. Little information on the diagnosis and treatment of Sheehan's syndrome with diabetes insipidus is available. We report on a 28-year-old patient who developed acute Sheehan's syndrome with diabetes insipidus after giving birth, and on a systematic review of similar cases.
METHODS
We performed a systematic review of the literature cataloged in PubMed and Google Scholar using the keywords "Sheehan syndrome" OR "Sheehan's syndrome" AND "diabetes insipidus" to identify relevant case reports published between 1990 and 2021. Eight Reports met the inclusion criteria (English-language abstracts available, onset in the puerperium, information about the day of the onset).
RESULTS
In the present case, postpartum curettage was necessary to remove the residual placenta. The total amount of blood loss was severe (2500 ml). On the second day postpartal, the patient developed polyuria. Laboratory analysis revealed hypernatremia with increased serum osmolality and decreased urinary osmolality. Hormone analysis showed partial hypopituitarism involving the thyroid, corticotropic, and gonadotropic axes. The prolactin level was elevated. Brain magnetic resonance imaging showed pituitary gland infarction. Desmopressin therapy was initiated and resolved the polyuria. Hormone replacement therapy was administered. Four months later, the patient was well, with partial diabetes insipidus. The literature review indicated that this case was typical in terms of symptoms and disease onset. Most reported cases involve hypotension and peripartum hemorrhage, but some patients without hemorrhage also develop Sheehan's syndrome. Elevated prolactin levels are uncommon and associated with poor prognosis in patients with Sheehan's syndrome.
CONCLUSION
Acute Sheehan's syndrome with diabetes insipidus involves nearly all pituitary hormone axes, indicating severe disease. Prolactin elevation could suggest that a case of Sheehan's syndrome is severe.
