Review
Wolfram-like syndrome (WFLS) is a recently described autosomal dominant disorder with phenotypic similarities to autosomal recessive Wolfram syndrome (WS), including optic atrophy, hearing impairment, and diabetes mellitus. We summarize current literature, define the clinical characteristics, and investigate potential genotype phenotype correlations. A systematic literature search was conducted in electronic databases Pubmed/MEDLINE, EMBACE, and Cochrane Library. We included studies reporting patients with a clinical picture consisting at least 2 typical clinical manifestations of WSF1 disorders and heterozygous mutations in WFS1. In total, 86 patients from 35 studies were included. The most common phenotype consisted of the combination of optic atrophy (87%) and hearing impairment (94%). Diabetes mellitus was seen in 44% of the patients. Nineteen percent developed cataract. Patients with missense mutations in WFS1 had a lower number of clinical manifestations, less chance of developing diabetes insipidus, but a younger age at onset of hearing impairment compared to patients with nonsense mutations or deletions causing frameshift. There were no studies reporting decreased life expectancy. This review shows that, within the spectrum of WFS1-associated disorders or "wolframinopathies," autosomal dominantly inherited WFLS has a relatively mild phenotype compared to autosomal recessive WS. The clinical manifestations and their age at onset are associated with the specific underlying mutations in the WFS1 gene.

Meta-Analysis Review
OBJECTIVE
Accurate diagnosis of diabetes insipidus (DI) is of significant importance for correct management. We aimed to evaluate the diagnostic accuracy of copeptin level measurements in the differential diagnosis between DI and primary polydipsia (PP).
METHODS
A literature search of electronic databases from January 1, 2005, to July 13, 2022, was performed. Primary studies that evaluated the diagnostic accuracy of copeptin concentration in patients with DI and PP were considered eligible. Two reviewers independently screened relevant articles and extracted data. The Quality Assessment of Diagnostic Accuracy Studies 2 tool was used to assess the quality of the included studies. The hierarchical summary receiver operating characteristic model and bivariate method were used.
RESULTS
Seven studies including 422 patients with polydipsia-polyuria syndrome were included; of the 422 patients, 189 (44.79%) presented with arginine vasopressin deficiency (AVP-D, cranial DI) and 212 (50.24%) with PP. The summary estimates of the diagnostic performance of stimulated copeptin to differentiate between PP and AVP-D were 0.93 (95% CI, 0.89-0.97) for sensitivity and 0.96 (95% CI, 0.88-1.00) for specificity. Baseline copeptin level showed high performance in identifying AVP resistance (nephrogenic DI), with a pooled sensitivity of 1.00 (95% CI, 0.82-1.00) and specificity of 1.00 (95% CI, 0.98-1.00); however, it showed little value in the differentiation between PP and AVP-D.
CONCLUSION
Copeptin level measurement is a useful tool for the differential diagnosis of patients with DI and PP. Stimulation before copeptin measurement is necessary in the diagnosis of AVP-D.

Hypophysitis is defined as inflammation of the pituitary gland. It is a heterogeneous condition as it can originate from different parts of the pituitary gland, can be caused by different pathophysiological processes, and can be isolated or the manifestation of a underlying systemic disease. Hypophysitis usually presents with endocrine deficiencies, including diabetes insipidus, with varying patterns. A subset of patients presents with mass effects. The last decades major progress has been made in the understanding of this disease. New forms are now recognized, new diagnostics are being developed, and specific treatments are proposed. This review provides an overview of the current knowledge on hypophysitis using an aetiology-based approach and provides the clinician with a stepwise approach to the patient with (suspected) hypophysitis.

Meta-Analysis
BACKGROUND
Craniopharyngiomas account for 1.2% to 4.6% of all intracranial tumors. Although age at presentation is distributed bimodally, with a pediatric peak occurring between 5 and 15 years and an adult peak between 50 and 70 years, presentation, treatment, and outcome differences between these two craniopharyngioma populations have not been thoroughly characterized.
OBJECTIVE
To compare treatments and outcomes between adult and pediatric craniopharyngiomas.
METHODS
This is a systematic review and meta-analysis. Web of Science, MEDLINE, and Scopus databases were searched for primary studies reporting postoperative complications, functional outcomes, recurrence, and overall survival in patients with craniopharyngioma undergoing surgery.
RESULTS
The search yielded 1,202 unique articles, of which 106 (n=4,202 patients) met criteria for qualitative synthesis and 23 (n=735 patients) met criteria for meta-analysis. Compared with adult, pediatric craniopharyngiomas were less likely to present with visual defects (odds ratio [OR] 0.54, 95% CI 0.36-0.80) or cognitive impairment (OR 0.29, 95% CI 0.12-0.71) and more likely with headaches (OR 2.08, 95% CI 1.16-3.73). Children presented with significantly larger tumors compared with adults (standardized mean difference 0.68, 95% CI 0.38-0.97). Comparing functional outcomes, pediatric patients sustained higher rates of permanent diabetes insipidus (OR 1.70, 95% CI 1.13-2.56), obesity (OR 3.15, 95% CI 1.19-8.31), and cranial nerve and/or neurological defects (OR 4.87, 95% CI 1.78-13.31) than adults. No significant differences were found in rates of postoperative cerebrospinal fluid leak, overall or progression-free survival, or recurrence.
CONCLUSION
Adult and pediatric craniopharyngiomas seem to have fundamental differences in clinical presentation and functional outcomes. These patients frequently require multimodality treatment and are best managed with a multidisciplinary team and an individualized approach.

Review
PURPOSE
Granulomatosis with polyangiitis (GPA) is a multisystem disease, characterized by necrotizing small-vessel vasculitis, which mainly affects the respiratory tract and the kidneys. Pituitary involvement in GPA is rare, present in about 1% of all cases of GPA. To date, only case reports or small case series have been published. Herein we report clinical features, imaging findings, treatment and outcomes in three patients with GPA-related pituitary dysfunction (PD).
METHODS
A retrospective analysis of three cases of GPA-related PD was conducted, followed by systematic review of the English medical literature using PubMed.
RESULTS
The three cases include three women aged between 32 and 37 years. PD was the presenting feature in one and two developed PD in the course of the disease. All patients had a pituitary lesion on MRI. Conventional treatment with high doses of glucocorticoids and cyclophosphamide led to resolution or improvement of the MRI abnormalities, whereas it was not effective in restoring PD. A systematic review identified 51 additional patients, showing that GPA can lead to partial or global PD, either at onset or, during the course of the disease. Secondary hypogonadism is the predominant manifestation, followed by diabetes insipidus (DI). Sellar mass with central cystic lesion is the most frequent radiological finding.
CONCLUSION
GPA should be carefully considered in patients with a sellar mass and unusual clinical presentation with DI and systemic disease. Although conventional induction-remission treatment improves systemic symptoms and radiological pituitary abnormalities, hormonal deficiencies persist in most of the patients. Therefore, follow-up should include both imaging and pituitary function assessment.

BACKGROUND
Pituitary metastases are a rare complication of generalized cancer. Metastases to the pituitary gland occur in only 1% of patients operated on for sellar tumor. The most common presenting symptom in patients with pituitary metastases is diabetes insipidus, whereas this is rare in those with pituitary adenoma.
MATERIAL AND METHODS
This publication presents the cases of two patients with pituitary metastases and a systematic review of the literature. English-language publications related to pituitary metastases and published from 1957 to 2016 were identified using the PubMed database.
RESULTS
A total of 131 publications containing information about 259 patients (121 female and 138 male; mean age, 57.3 years) were identified. The most often metastasized breast carcinoma (24.6%) and lung carcinoma (23.8%), followed by thyroid carcinoma (11.3%), renal cell carcinoma (7.8%), hepatocellular carcinoma (4.3%), colorectal carcinoma (3.5%), and malignant melanoma (3.5%). The most frequent initial symptoms were manifestations of diabetes insipidus (39.6%), anterior pituitary deficiency (44.9%), perimeter disorders (51.6%), headache (37.6%), cranial nerve palsy (33.5%), and pseudoprolactinemia (16.7%). Radiotherapy (67.8%) and surgical treatment (63.9%) were the most frequently used treatment.
CONCLUSION
The average survival time from the onset of metastatic disease was 11.8 months. Surgical therapy alone or in combination with radiation therapy does not prolong survival, but alleviates symptoms and improves quality of life.Key words: pituitary metastasis - diabetes insipidus - hypopituitarism - transsphenoidal surgery The authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study.

CONTEXT
Pituitary adenomas are benign tumors, usually found in men in their 3 and 5 decades of life, representing 10-15% of all intracranial tumors. The clinical manifestations include important endocrinological disturbances and visual impairment.
OBJECTIVE
This study aimed to determine the most suitable neurosurgical approach regarding the dimensions, extensions and invasiveness of tumor extensions.
DESIGN
This was a systematic review of the literature from 2002-2022, focused on clinical outcome, especially endocrinological state according to the surgical approach.
SUBJECTS AND METHODS
We performed an advanced search on Web of Science and PubMed databases on October 10, 2022. The literature showed 300 studies in the last 20 years, and after we applied the inclusion and exclusion criteria's, 19 studies were fully read and analyzed.
RESULTS
Postoperative complications were reviewed in each surgical approach group, including visual impairment, new endocrinological disturbances, diabetes insipidus and cerebrospinal fluid leakage. Analyze of the endocrinological findings did not determined differences in transcranial groups from transsphenoidal groups. Overall complications were identified in the transcranial cohorts, while cerebrospinal fluid leakage still represent the main problem in transsphenoidal groups. The majority of studies found included extended endoscopic transsphenoidal approach, which shows results of great potential.
CONCLUSIONS
For the surgical treatment of pituitary adenoma, transsphenoidal procedure with or without extended approaches is preferred, but they're cases when a craniotomy is mandatory for a feasible gross tumor resection. Combined "above and below" simultaneous procedure or a two-staged intervention is recommended for giant pituitary adenoma, to maximize tumor resection and lower the risk of cerebrospinal fluid leakage.

BACKGROUND AND OBJECTIVE
Psychotropic drugs are a heterogenous group of treatments prescribed for many psychiatric disorders, often for long periods. Their effects on the kidney and its functioning are complex and a source of significant research and debate. This article aims to review recent evidence of the acute and chronic kidney adverse events of diverse psychotropes.
METHODS
A systematic search of randomized controlled trials and large observational studies (n ≥ 100) reporting the effects of psychotropic drugs on the kidney was conducted. The MEDLINE, PsycInfo, and EMBASE databases from 2011 to 2021, inclusive, were broadly searched with few restrictions and no prespecified outcomes. Two or more independent reviewers assessed and summarized all eligible studies, including risks of bias and levels of evidence.
RESULTS
In all, 1999 abstracts were screened for eligibility and 47 articles were included, which examined lithium (33), antiepileptics (10), antipsychotics (13), and antidepressants (9). No studies examining kidney adverse effects of other psychotropes, such as benzodiazepines, met inclusion criteria. Study populations were adult (8), geriatric (9), and mixed (30). Lithium was almost unanimously associated with (1) chronic kidney disease and (2) nephrogenic diabetes insipidus in methodologically diverse studies. The most supported risk factors for declining kidney functioning with lithium were advanced age, duration of lithium treatment, acute lithium toxicity, female sex, medications with known renal interactions, diabetes mellitus/hyperglycemia, and overall medical comorbidity. Supratherapeutic lithium concentrations are both the causes and consequences of acute kidney injury. Once significant chronic kidney disease has developed, four studies found that replacing lithium with other mood stabilizers does not slow progression, and the evolution to end-stage kidney disease is rare overall with modern practices. Compared to lithium, fewer studies examined antipsychotics and antiepileptics but found relatively less direct kidney harms. Antidepressants were not associated with acute or chronic kidney harms.
CONCLUSIONS
Despite the heterogeneity of findings, owing to varying methodologies and research challenges, recent studies strongly suggest that lithium is associated with an increased risk of chronic kidney disease and nephrogenic diabetes insipidus, especially in older adults and long-term lithium users. Clinicians should balance the harms of lithium against its established benefits, and ensure adequate monitoring and management of comorbidities in all patients. Weaker evidence suggests that antiepileptics such as valproate and antipsychotics result in comparatively less harm to the kidney than lithium, but warrant monitoring because of multiple direct and indirect mechanisms for potential kidney adverse events. Antidepressants do not have clear kidney adverse effects and appear safe (though potentially less effective) in the setting of kidney disease. Other classes of psychotropic drugs have received little research interest. Further research is warranted, particularly into specific antiepileptics and antipsychotics, and careful attention should be paid to mitigating important sources of bias such as confounding by indication.

Meta-Analysis Review
PURPOSE
Hypopituitarism is a rare disorder with significant morbidity. To study the evidence on the association of premature mortality and hypopituitarism.
METHODS
A comprehensive search of multiple databases: MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus was conducted through August, 2015. Eligible studies that evaluated patients with hypopituitarism and reported mortality estimates were selected following a predefined protocol. Reviewers, independently and in duplicate, extracted data and assessed the risk of bias.
RESULTS
We included 12 studies (published 1996-2015) that reported on 23,515 patients. Compared to the general population, hypopituitarism was associated with an overall excess mortality (weighted SMR of 1.55; 95 % CI 1.14-2.11), I = 97.8 %, P = 0.000. Risk factors for increased mortality included younger age at diagnosis, female gender, diagnosis of craniopharyngioma, radiation therapy, transcranial surgery, diabetes insipidus and hypogonadism.
CONCLUSION
Hypopituitarism may be associated with premature mortality in adults. Risk is particularly higher in women and those diagnosed at a younger age.

Meta-Analysis Review
INTRODUCTION
Many studies have explored the relationship between diabetes mellitus (DM) and tuberculosis (TB) demonstrating increased risk of TB among patients with DM and poor prognosis of patients suffering from the association of DM/TB. Owing to a paucity of studies addressing this question, it remains unclear whether patients with DM and TB are more likely than TB patients without DM to be grouped into molecular clusters defined according to the genotype of the infecting Mycobacterium tuberculosis bacillus. That is, whether there is convincing molecular epidemiological evidence for TB transmission among DM patients. Objective: We performed a systematic review and meta-analysis to quantitatively evaluate the propensity for patients with DM and pulmonary TB (PTB) to cluster according to the genotype of the infecting M. tuberculosis bacillus.
MATERIALS AND METHODS
We conducted a systematic search in MEDLINE and LILACS from 1990 to June, 2016 with the following combinations of key words "tuberculosis AND transmission" OR "tuberculosis diabetes mellitus" OR "Mycobacterium tuberculosis molecular epidemiology" OR "RFLP-IS6110" OR "Spoligotyping" OR "MIRU-VNTR". Studies were included if they met the following criteria: (i) studies based on populations from defined geographical areas; (ii) use of genotyping by IS6110- restriction fragment length polymorphism (RFLP) analysis and spoligotyping or mycobacterial interspersed repetitive unit-variable number of tandem repeats (MIRU-VNTR) or other amplification methods to identify molecular clustering; (iii) genotyping and analysis of 50 or more cases of PTB; (iv) study duration of 11 months or more; (v) identification of quantitative risk factors for molecular clustering including DM; (vi) > 60% coverage of the study population; and (vii) patients with PTB confirmed bacteriologically. The exclusion criteria were: (i) Extrapulmonary TB; (ii) TB caused by nontuberculous mycobacteria; (iii) patients with PTB and HIV; (iv) pediatric PTB patients; (v) TB in closed environments (e.g. prisons, elderly homes, etc.); (vi) diabetes insipidus and (vii) outbreak reports. Hartung-Knapp-Sidik-Jonkman method was used to estimate the odds ratio (OR) of the association between DM with molecular clustering of cases with TB. In order to evaluate the degree of heterogeneity a statistical Q test was done. The publication bias was examined with Begg and Egger tests. Review Manager 5.3.5 CMA v.3 and Biostat and Software package R were used.
RESULTS
Selection criteria were met by six articles which included 4076 patients with PTB of which 13% had DM. Twenty seven percent of the cases were clustered. The majority of cases (48%) were reported in a study in China with 31% clustering. The highest incidence of TB occurred in two studies from China. The global OR for molecular clustering was 0.84 (IC 95% 0.40-1.72). The heterogeneity between studies was moderate (I2 = 55%, p = 0.05), although there was no publication bias (Beggs test p = 0.353 and Eggers p = 0.429).
CONCLUSION
There were very few studies meeting our selection criteria. The wide confidence interval indicates that there is not enough evidence to draw conclusions about the association. Clustering of patients with DM in TB transmission chains should be investigated in areas where both diseases are prevalent and focus on specific contexts.
