Meta-Analysis
Neurocognitive and psychological dysfunctions associated with pituitary adenomas (PAs) are clinically relevant, though probably under-reported. The aim of the current review is to provide an update on neuropsychological status, psychopathology, and perceived quality of life (QoL) in patients with PAs. A systematic research was performed in PubMed and Scopus in order to identify reports on neurocognitive, psychiatric, and psychological disorders in PAs. Prevalence of alterations, QoL evaluation, and used tests were also recorded. PRISMA guidelines were followed. Of 62,448 identified articles, 102 studies were included in the systematic review. The prevalence of neurocognitive dysfunctions was 15-83% in Cushing's Disease (CD), 2-33% in acromegaly, mostly affecting memory and attention. Memory was altered in 22% of nonfunctioning (NF) PAs. Worsened QoL was reported in 40% of CD patients. The prevalence of psychiatric disorders in CD reached 77% and in acromegaly 63%, mostly involving depression, followed by psychosis, and anxiety. The prevalence of psychopathology was up to 83% in CD, and 35% in acromegaly. Postoperative improvement in patients with CD was observed for: learning processes, overall memory, visuospatial skills, and language skills. Short-term memory and psychomotor speed improved in NFPAs. Postoperative improvement of QoL, somatic symptoms, obsessive-compulsive disorder, and coping strategies was seen in CD and acromegaly. Reports after radiotherapy are discordant. There is wide variability in used tests. PAs have been recently shown to be associated with altered neurocognitive and neuropsychological functions, as well as QoL. These data suggest the importance of a multidisciplinary evaluation for an optimal management.

Meta-Analysis
An association exists between nonalcoholic fatty liver disease (NAFLD) and growth hormone (GH). Patients with growth hormone deficiency (GHD) may be more susceptible to NAFLD. The prevalence of NAFLD and nonalcoholic steatohepatitis (NASH) in GHD patients is currently unknown. Multiple databases were searched for experiments related to NAFLD (or NASH) and GHD. Screening, quality evaluation and data extraction were carried out independently by two authors. Analyses used random or fixed effects models, including NAFLD prevalence, NASH prevalence, odds ratio (OR) and 95% confidence interval (CI). We included 10 studies with a total of 782 participants. The results showed that the prevalence of NAFLD in GHD patients was 51% (95% CI: 39-63). The risk of NAFLD in GHD patients was significantly higher than that in controls (age-, sex- or body mass index-matched, without GHD) (pooled OR = 4.27, 95% CI: 1.33-13.68%, p = 0.015). The prevalence of NASH in GHD patients was 18% (95% CI: 5-31). The prevalence of NAFLD in GHD patients is significantly higher than that in the general population, especially NASH. There is a need to develop targeted strategies for the early identification, prevention, or control of NAFLD/NASH in patients with GHD.

Meta-Analysis Review
PURPOSES
Brachytherapy has been indicated as an alternative option for treating cystic craniopharyngiomas. Despite the difficulties regarding the complex nuclear infrastructure and consequent small number of brachytherapy studies, recent discoveries relating tumour characteristics to sensitivity to brachytherapy have stimulated this extensive systematic review and meta-analysis of the recent results aiming to summarise its efficacy and complications.
METHODS
The systematic review was structured using PRISMA statements. The MEDLINE database was systematically reviewed from March 2010 to February 2021 to identify qualified trials dealing with radioisotope brachytherapy in cystic craniopharyngiomas in the paediatric population, emphasising tumour control rates and complications.
RESULTS
A total of 228 individuals were analysed, of which 66 were children. The minimum average follow-up was 5 years. Considering the paediatric trials, partial and complete responses were achieved in 89% of patients with exclusively cystic lesions, compared to 58% in non-exclusively cystic lesions. The former observed progression in 3% of patients, while in the latter, 35% was reported. Visual and endocrine improvement reached 64% and 20%, respectively, in the first group, in contrast to 48% and 7% in the second group, respectively. There were similar results considering the non-exclusive paediatric series, but with less expressive numbers.
CONCLUSION
These results reinforce the positive impact of radioisotope brachytherapy in the treatment of predominant monocystic or multicystic craniopharyngiomas, especially in the paediatric population, grounded by impressive tumour control rates, lower morbidities and single application in the majority of the cases. In the future, specific morphological tumour characteristics might be considered for a more assertive patient selection.

Review
OBJECTIVE
This study reviews the presentation, management, and outcomes of patients with rhinolithiasis.
DATA SOURCES
An electronic database search of PubMed, SCOPUS, CINAHL, and the Cochrane Library was performed in accordance with the PRISMA 2020 updated guidelines for reporting systematic reviews.
REVIEW METHODS
Case reports and case series published from 2004 to 2020 were included. Data collected included patient demographics, clinical symptoms at presentation, diagnosis, treatment, complications, and follow-up. Relevant descriptive statistics were computed using Microsoft Excel 2013 (Microsoft Corp).
RESULTS
Fifty-five case reports and five case series were included (n = 122). The majority were female (60.7%). The mean age was 29.4 years (range, 4-80 years). The most common symptoms were rhinorrhea (81.1%), nasal obstruction (79.5%), nasal malodor (38.5%), and headache (27.9%). Computed tomography imaging was obtained in 109 (91.5%) cases. Concurrent rhinosinusitis (35.2%) and deviated nasal septum (28.7%) were commonly identified. Rhinoliths were commonly found in the right nostril (52.5%) and in between the inferior turbinate and nasal septum (26.9%). All rhinoliths were fully excised using endoscopic sinonasal surgery, accompanied by a septoplasty (9.2%). The nidus was identified in 27 (22.2%) patients. There were no recurrences or complications over an average follow-up of 8.5 months (range, 0.25-36 months).
CONCLUSION
Rhinolithiasis is an uncommon entity of the nasal cavity and should be suspected in patients with long-standing unilateral nasal obstruction, rhinorrhea, and nasal malodor. Rigid nasal endoscopy and endoscopic sinonasal surgery are the most important methods for diagnosis and treatment, respectively.

Review
Pituitary tumors (PT) are mostly benign, although occasionally they demonstrate aggressive behavior, invasion of surrounding tissues, rapid growth, resistance to conventional treatments, and multiple recurrences. The pathogenesis of PT is still not fully understood, and the factors responsible for its invasiveness, aggressiveness, and potential for metastasis are unknown. RAF/MEK/ERK and mTOR signaling are significant pathways in the regulation of cell growth, proliferation, and survival, its importance in tumorigenesis has been highlighted. The aim of our review is to determine the role of the activation of PI3K/AKT/mTOR and RAF/MEK/ERK pathways in the pathogenesis of pituitary tumors. Additionally, we evaluate their potential in a new therapeutic approach to provide alternative therapies and improved outcomes for patients with aggressive pituitary tumors that do not respond to standard treatment. We perform a systematic literature search using the PubMed, Embase, and Scopus databases (search date was 2012-2023). Out of the 529 screened studies, 13 met the inclusion criteria, 7 related to the PI3K/AKT/mTOR pathway, and 7 to the RAF/MEK/ERK pathway (one study was used in both analyses). Understanding the specific factors involved in PT tumorigenesis provides opportunities for targeted therapies. We also review the possible new targeted therapies and the use of mTOR inhibitors and TKI in PT management. Although the RAF/MEK/ERK and PI3K/AKT/mTOR pathways play a pivotal role in the complex signaling network along with many interactions, further research is urgently needed to clarify the exact functions and the underlying mechanisms of these signaling pathways in the pathogenesis of pituitary adenomas and their role in its invasiveness and aggressive clinical outcome.

Meta-Analysis
CONTEXT
The increased use of opioids has resulted in an unprecedented opioid epidemic. Chronic opioid use causes hypogonadism, but its frequency, as well as the effects of opioids on other hypothalamo-pituitary-end organ hormone axes, remains unclear.
OBJECTIVE
The aim of this systematic review and meta-analysis was to assess the effects of opioid use on pituitary function.
METHODS
Eight electronic databases were searched for articles published up to May 8, 2018. Fixed or random effects meta-analysis was performed to estimate pooled proportions with 95% confidence intervals (CI). This study is reported following the PRISMA and MOOSE guidelines.
DATA SYNTHESIS
52 studies (22 low risk of bias) were included describing 18 428 subjects, consisting of patients with chronic pain (n = 21 studies) or on maintenance treatment for opioid addiction (n = 9) and healthy volunteers (n = 4). The most frequently used opioid was methadone (n = 13 studies), followed by morphine (n = 12). Prevalence of hypogonadism was 63% (95% CI: 55%-70%, 15 studies, 3250 patients, 99.5% males). Prevalence of hypocortisolism relying on dynamic and nondynamic testing was 15% (95% CI: 6%-28%, 5 studies, 205 patients, 57.5% males) and including only studies using the insulin tolerance tests 24% (95% CI 16%-33%, 2 studies, n = 97 patients). In 5 out of 7 studies, hyperprolactinemia was present. No clear effects on the somatotropic and hypothalamo-pituitary-thyroid axes were described.
CONCLUSIONS
Hypogonadism occurs in more than half of male opioid users, and hypocortisolism in approximately one-fifth of all patients. Periodical evaluation of at least the gonadal and adrenal axes is therefore advisable.

Meta-Analysis
The management of non-functioning pituitary tumors (NFPTs) relies on the risk of tumor growth and new endocrinopathies. The objective of this systematic review was to assess the risk of growth, new pituitary endocrinopathies, and surgery in patients with conservatively treated NFPTs. We conducted a bibliographical search identifying studies assessing NFPTs followed conservatively. Estimates were pooled using random-effects meta-analysis reporting events per 100 person years (PYs), in case of high heterogeneity (I2>75%) only the range of observed effects was reported. We identified 30 cohort studies including 1957 patients with a mean follow-up time of 4.0 (SD 1.5) years. The overall risk of tumor growth ranged from 0.0 to 14.2/100 PYs (I2=90%), while the overall risk of new endocrinopathies was 0.9/100 PYs (95% CI. 0.5 to 1.2; I2=: 35%) and risk of surgery ranged from 0.0 to 7.7/100 PYs (I2=: 80%). Compared to microadenomas, macroadenomas had higher risk of growth (p=: 0.002), higher risk of surgery (p=: 0.006), and non-significant differences in risk of new endocrinopathies (p=: 0.15). An analysis of microadenomas found the risk of growth to be 1.8/100 PYs (95% CI. 0.9 to 2.8; I2=: 58%), the risk of new endocrinopathies 0.7/100 PYs (95% CI. 0.0 to 1.6; I2=: 37%) and the risk of surgery 0.5/100 PYs (0.1 to 0.9; I2=: 37%). These data support individualized follow-up strategies of patients with NFPTs and particularly a less rigorous follow-up of patients with microadenomas.

Review
BACKGROUND
Craniopharyngiomas are morbid tumors that significantly reduce patients' quality of life (QoL). The lifelong burden of endocrine, visual, hypothalamic, and limbic dysfunction can have disastrous consequences for the physical and psychosocial health of patients. Elucidating the factors that influence QoL could guide therapeutic interventions to improve patient well-being.
METHODS
A systematic review was performed in accordance with the PRISMA (preferred reporting items for systematic reviews and meta-analyses) statement using the PubMed and Medline databases. Studies that had reported patient QoL using validated metrics in both adult and pediatric populations were included. Bias and methodological rigor were assessed using the MINORS (methodological index for nonrandomized studies) criteria.
RESULTS
A total of 25 studies, including 2025 patients, were available for review. Most studies were small, retrospective, cohort studies with a high risk of bias. The QoL of the patients with craniopharyngioma was lower than that of the general population. Hypothalamic involvement was consistently the strongest predictor of QoL. Endocrinopathy contributed to morbidity but could be ameliorated by hormone replacement therapy. Social and emotional dysregulation and a poor memory are common complaints after surgery, and iatrogenic damage to the infundibulum, hypothalamus, limbic system, and frontal lobes might underlie these concerns. Sleep-wake cycle dysfunction and hypothalamic obesity are serious consequences of hypothalamic damage.
CONCLUSIONS
An experienced multidisciplinary team is necessary to optimally manage the complex cases of these patients. The poor QoL of patients with craniopharyngioma is multifactorial. However, the contribution of iatrogenesis is not insubstantial. Improved surgical techniques, focusing on hypothalamic preservation, and adjuvant treatment options are required to improve the well-being of these patients.

Review
BACKGROUND
Septo-optic dysplasia (SOD) is a rare condition diagnosed in children with two or more of the following: hypopituitarism, midline brain abnormalities, and optic nerve hypoplasia. Children with SOD experience varied visual impairment and endocrine dysfunction. Autistic-like behaviours have been reported; however, their nature and prevalence remain to be fully understood. The present systematic review aimed to explore the type and prevalence of neurodevelopmental impairments in children with SOD spectrum conditions.
METHODS
The search was conducted in PubMed, EMBASE, and PsycInfo. Hand-searching reference lists of included studies was conducted. All peer-reviewed, observational studies assessing behavioural and cognitive impairments or autism spectrum disorder (ASD) symptoms in children (< 18 years) with SOD, optic nerve hypoplasia, and SOD-plus were included. Studies were excluded if they did not report standardised measures of neurodevelopmental impairments or ASD outcomes.
RESULTS
From 2132 screened articles, 20 articles reporting data from a total of 479 children were included in prevalence estimates. Of 14 studies assessing cognitive-developmental outcomes, 175 of 336 (52%) children presented with intellectual disability or developmental delay. A diagnosis of ASD or clinical level of symptoms was observed in 65 of 187 (35%) children across five studies. Only five studies assessed for dysfunction across behavioural, emotional, or social domains and reported impairments in 88 of 184 (48%) of children assessed.
LIMITATIONS
Importantly, high heterogeneity among the samples in relation to their neuroanatomical, endocrine, and optic nerve involvement meant that it was not possible to statistically assess the relative contribution of these confounding factors to the specific neurodevelopmental phenotype. This was further limited by the variation in study designs and behavioural assessments used across the included studies, which may have increased the risk of information bias.
CONCLUSIONS
This systematic review suggests that the prevalence of neurodevelopmental impairments in children within the SOD spectrum may be high. Clinicians should therefore consider including formal assessments of ASD symptoms and neurodevelopmental impairments alongside routine care. There is, additionally, a need for further research to define and validate a standardised battery of tools that accurately identify neurodevelopmental impairments in SOD spectrum conditions, and for research to identify the likely causal mechanisms.

Review
PURPOSE
Giant prolactinomas are a rare entity, representing approximately 5% of all prolactinomas. A systematic review of 196 adult cases was performed. A comparison of the clinical, biochemical and radiological characteristics, management and therapeutic outcomes in men versus women is made.
METHODS
A structured search was conducted using the term 'giant prolactinoma'. Following inclusion criteria were used: diameter ≥ 40 mm, prolactin levels > 1000 ng/ml and no concomitant GH/ ACTH secretion.
RESULTS
196 cases were included [age: 38 (28-50) years, F/M ratio: 1/3.6]. Median tumor diameter was 53 (43-69) mm. Pituitary deficiency was present in 91% of cases, with hypogonadotropic hypogonadism being the most frequent. Most common presenting symptoms were visual impairment (73%) and headache (50%) in men and amenorrhea (58%) in women. 82% of cases were treated with a dopamine agonist (DA) as first-line treatment which led to normoprolactinemia, tumor shrinkage and visual improvement in 51%, 88% and 85% of cases, respectively. Surgery was performed in 29% of cases and all showed tumor remnant and persistent hyperprolactinemia. Women had a lower prolactin level and a smaller tumor diameter at diagnosis but pituitary deficiencies were more frequent and outcome was worse.
CONCLUSION
Giant prolactinomas are rare and have a male predominance. Visual impairment is the most frequent presenting symptom in men and amenorrhea in women. The gender-related difference in tumor size and level of prolactin was confirmed in this analysis where men had a larger diameter and a higher baseline prolactin level. DAs are the treatment of choice, irrespective of tumor size and presence of visual impairment. As only half of the cases achieved normoprolactinemia we do not, in contrast to previous literature, state giant prolactinomas to be exquisitely sensitive to DAs. Patient characteristics associated with persistent hyperprolactinemia after treatment with a DA were female gender, higher baseline prolactin and larger tumor size . This analysis did show TSH- and ACTH-deficiency to be more frequent after surgery which was not seen for LH/FSH deficiency.
