Management of a Posterior Mesotympanic Cholesteatoma using the Transcanal Endoscopic Approach.

With the constant evolution in the role of endoscopy in middle ear surgery, this article presents a technical note on the transcanal endoscopic approach to resection of a cholesteatoma limited to the posterior mesotympanum. We believe that this technique provides a suitable, minimal-invasive alternative to the classic microscopic transmastoid approach.

Tobacco use in first-episode psychosis, a multinational EU-GEI study.

BACKGROUND: Tobacco is a highly prevalent substance of abuse in patients with psychosis. Previous studies have reported an association between tobacco use and schizophrenia. The aim of this study was to analyze the relationship between tobacco use and first-episode psychosis (FEP), age at onset of psychosis, and specific diagnosis of psychosis. METHODS: The sample consisted of 1105 FEP patients and 1355 controls from the European Network of National Schizophrenia Networks Studying Gene-Environment Interactions (EU-GEI) study. We assessed substance use with the Tobacco and Alcohol Questionnaire and performed a series of regression analyses using case-control status, age of onset of psychosis, and diagnosis as outcomes and tobacco use and frequency of tobacco use as predictors. Analyses were adjusted for sociodemographic characteristics, alcohol, and cannabis use. RESULTS: After controlling for cannabis use, FEP patients were 2.6 times more likely to use tobacco [p ⩽ 0.001; adjusted odds ratio (AOR) 2.6; 95% confidence interval (CI) [2.1-3.2]] and 1.7 times more likely to smoke 20 or more cigarettes a day (p = 0.003; AOR 1.7; 95% CI [1.2-2.4]) than controls. Tobacco use was associated with an earlier age at psychosis onset (ß = -2.3; p ⩽ 0.001; 95% CI [-3.7 to -0.9]) and was 1.3 times more frequent in FEP patients with a diagnosis of schizophrenia than in other diagnoses of psychosis (AOR 1.3; 95% CI [1.0-1.8]); however, these results were no longer significant after controlling for cannabis use. CONCLUSIONS: Tobacco and heavy-tobacco use are associated with increased odds of FEP. These findings further support the relevance of tobacco prevention in young populations.

Psychiatric Admission Among Migrants Before and During Pandemic: a Retrospective Study in Acute Psychiatric Ward in Bologna, Italy.

Previous evidence showed significant discrepancies in psychiatric services utilization between migrants and reference populations. Our study aims were to evaluate incidence and characteristics of psychiatric hospitalizations of migrant patients compared with reference populations and to assess how the COVID-19 pandemic affected admissions. All patients admitted to the psychiatric ward "SPDC-Malpighi" of the Bologna Mental Health Department from 01/01/2018 to 31/12/2020 were included. Differences in sociodemographic and clinical characteristics were tested by migrant status. Incidence rate ratios of hospital admissions by migrant status were estimated via Poisson regression considering population-at-risk, gender, and age-group. Migrants had higher hospitalization rates due to any psychiatric disorder (IRR = 1.16). The risk was especially pronounced among women (IRR = 1.25) and within the youngest age-group (IRR = 3.24). Young migrants had also a greater risk of compulsory admission (IRR = 3.77). Regarding admissions due to a specific diagnosis, we found relevant differences in hospitalization rates for psychosis, mood disorders, and personality disorders. Finally, migrants were more likely to be admitted via Emergency Department and less likely to be referred from a specialist. During the year of pandemic (2020) we observed an increase in the proportion of migrants admitted voluntarily or compulsorily. Migrants, especially those from the youngest age-group, had higher hospitalization rates for any disorder. Younger migrants were also at higher risk of compulsory treatment. The distribution of psychiatric admissions during the pandemic period seemed to have further increased discrepancies in mental healthcare needs and provision between migrants and the reference population. Tailored interventions and policies are urgently needed to address this issue.

Exposure to psychotropic medications and COVID-19 course after hospital admission: Results from a prospective cohort study.

OBJECTIVE: There is evidence of a bidirectional association between COVID-19 disease and psychiatric disorders. We aimed to assess whether exposure to psychotropic medications prior to hospitalization was associated with mortality or discharge within 30 days after hospital admission. METHODS: In this prospective study, we included all individuals with a laboratory-confirmed COVID-19 infection who were admitted to the Bologna University Hospital between 1st March 2020 and 31st January 2021. We collected data about pre-existing psychiatric disorders and the use of psychotropic medications at the admission. As univariate analyses, we estimated cumulative incidence functions for 30-day mortality and discharge stratifying by exposure to each of the psychotropic medication classes. Finally, we fitted Cox regression models to estimate cause-specific Hazard Ratios (HR) of 30-day mortality and discharge. Results were adjusted for sociodemographic (age, sex), clinically relevant variables (comorbidity, c-reactive protein levels, severity of disease at presentation, history of smoking, study period), and psychiatric variables (psychiatric disorder diagnosis, number of psychotropic medications). RESULTS: Out of a total of 1238 hospitalized patients, 316 were prescribed psychotropic medications at the time of admission. Among these, 45 (3.6%) were taking a first-generation antipsychotics (FGA) and 66 (5.3%) a second generation antipsychotic (SGA). Exposure to SGA was associated with increased rates of 30-day mortality (HR = 2.01, 95%CI = 1.02-3.97) and exposure to FGA was associated with decreased rates of 30-day discharge (HR = 0.55, 95%CI = 0.33-0.90). CONCLUSION: Patients with COVID-19 infection exposed to FGA and SGA may have worse COVID-19 infection outcomes.

Evaluation of Eye Movement Desensitization and Reprocessing in the management of tinnitus. An observational study.

OBJECTIVES: Tinnitus can induce disabling psychological suffering, requiring an integrative multimodal approach, combining neuromodulation and psychotherapeutic methods. We sought to evaluate the therapeutic efficacy and acceptability of Eye Movement Desensitization and Reprocessing (EMDR) in tinnitus. MATERIALS AND METHODS: This was a single-center prospective non-comparative study. Inclusion criteria comprised: adult patient, with chronic tinnitus, Tinnitus Handicap Inventory (THI) score>17, causing psychological distress motivating active treatment after ineffective "classic" treatment (combining advice, sound therapy and first-line drug treatment), and agreement to EMDR therapy. Therapeutic efficacy was defined by a decrease in THI or Visual Analog Scale (VAS) scores. Treatment acceptability was defined by the rate of included patients who completed therapy. RESULTS: Thirty-eight patients were included. There was a significant reduction of 53.5% in THI score in 78.9% of patients (P<0.0001; 64.8±20.8 before versus 31.8±24.7 after treatment), and of 51% in VAS score in 76.3% of patients (P<0.0001; 7.24±2.12 before versus 3.58±2.03 after treatment). The treatment acceptability was 86.8%. CONCLUSION: EMDR appeared to be an effective alternative that was acceptable to the majority of patients, after failure of "classic" first-line treatment, improving quality of life in tinnitus patients and thus relieving disability.

Language proficiency and mental disorders among migrants: A systematic review.

BACKGROUND: In this review, we aimed to evaluate the association between language proficiency (LP) and the prevalence and severity of mental disorders in migrants. Secondarily, we aimed to consider whether sociodemographic and migration-related factors may affect the correlation between LP and mental disorders. METHODS: MEDLINE, PsycArticles, EMBASE, and PsycInfo were systematically searched in April 2020 to identify original studies reporting prevalence of psychiatric symptoms or disorders among migrants and taking into account linguistic factors. RESULTS: The search of electronic databases initially yielded 1,944 citations. Of the 197 full texts assessed for eligibility, 41 studies were selected for inclusion in the systematic review. Thirty-five of the papers included reported a significant negative association between low LP and prevalence and/or severity of psychiatric symptoms or disorders, whereas only two records found the opposite relationship and four papers reported no association between them. Inadequate LP was consistently associated with several mental disorders in migrants, including psychotic, mood, anxiety, and post-traumatic stress disorders. Notably, all the four longitudinal studies that met inclusion criteria for this review reported a positive effect of LP acquisition over time on prevalence or symptom severity of mental disorders. CONCLUSIONS: Even though larger prospective studies are needed to better evaluate the relationship between LP and psychiatric disorders among migrants, we believe that the present findings could be inspiring for authorities to provide support and courses to improve migrants' language proficiency upon arrival.

Health conditions of migrants landed in north-eastern Sicily and perception of health risks of the resident population.

OBJECTIVES: In Italy, a recent irregular movement of people raised concerns among the host population on possible introduction of diseases that have long been controlled in the host countries. This study evaluates the health conditions of illegal immigrants landed on the north-eastern Sicilian territory, to provide information on the clinical and epidemiologic burden of infectious diseases among migrants and how the local population feel about these landings. STUDY DESIGN: The study design is a cross-sectional study. METHODS: The study considered all migrants landed illegally in the city of Messina, Sicily, between January 2014 and July 2018. Analysing the data of hospital admissions and disease notifications, we calculated the frequency of infectious diseases among migrant population. Furthermore, through a survey conducted by a well-known online newspaper, we analysed the perception that the local population has about the health risk represented by migrants. RESULTS: In the considered five-year period, 108 landings, for a total of 38,608 migrants occurred at the Messina port. The percentage of hospitalisation was rather low (3.5%), and it concerned mainly pregnant women. The notifications of infectious diseases were contained, with exception of scabies and tuberculosis. Finally, from the online survey, resulted that there is a large part of local population that considers migrants a potential danger to community health. CONCLUSIONS: Our data show that the presence of migrants should not have to date any impact on the health conditions of the resident population. However, monitoring over time the health of migrants and screening for infectious diseases as soon as possible after landing are advantageous for both migrants and host country.

The role of neurotransmitters and neuromodulators in the pathogenesis of cluster headache: a review.

The pathogenesis underlying cluster headache remains an unresolved issue. Although both the autonomic system and the hypothalamus play a central role, the modality of their involvement remains largely unknown. It is, also, unknown why the duration of the pain attacks is so brief and why their onset and termination are abrupt and extremely painful. This review summarizes the evidence to date accumulated in favor of a possible role of anomalies in the metabolism of tyrosine, tryptophan, and arginine in these unresolved issues.

Measles outbreak from February to August 2017 in Messina, Italy.

INTRODUCTION: Measles continues to be a major public health issue worldwide, with high morbidity and mortality rates. The disease remains endemic in 14 European countries, including Italy where, from 2013 to 2016, over 5,000 cases have been reported. In 2017, many Italian regions, including Sicily, have reported many cases of measles. In this study, we described the latest measles outbreak in the city of Messina, from 1st February to 31st August 2017. METHODS: We considered all reported measles cases that came to the "Public Health, Epidemiology and Preventive Medicine" Operative Unit of the Messina Provincial Health Agency Prevention Department, which receives all reported cases of measles in the Messina province. RESULTS: From 1st February to 31st August 2017, a total of 59 measles cases were reported, of which 44 were confirmed, nine were classified as possible, four were probable and two cases were discarded. Of the 57 possible, probable and confirmed cases, 31 (54%) were males and 26 (46%) were females. Moreover, 54 (95%) had not been previously vaccinated while the remaining cases had documented evidence of one (two cases) or two doses (one case). Genotype B3 was identified in 39/44 cases (88,6%) by the regional reference laboratory in Palermo. CONCLUSIONS: Despite the development of an effective vaccination, unfortunately measles continues to threaten the lives of millions of children worldwide each year. The suboptimal immunization level in Italy has led to an increase in the transmission of measles with detrimental effects on both public health and ongoing measles elimination efforts.

Oncologist use and perception of large panel next-generation tumor sequencing.

BACKGROUND: Genomic profiling is increasingly incorporated into oncology research and the clinical care of cancer patients. We sought to determine physician perception and use of enterprise-scale clinical sequencing at our center, including whether testing changed management and the reasoning behind this decision-making. PATIENTS AND METHODS: All physicians who consented patients to MSK-IMPACT, a next-generation hybridization capture assay, in tumor types where molecular profiling is not routinely performed were asked to complete a questionnaire for each patient. Physician determination of genomic 'actionability' was compared to an expertly curated knowledgebase of somatic variants. Reported management decisions were compared to chart review. RESULTS: Responses were received from 146 physicians pertaining to 1932 patients diagnosed with 1 of 49 cancer types. Physicians indicated that sequencing altered management in 21% (331/1593) of patients in need of a treatment change. Among those in whom treatment was not altered, physicians indicated the presence of an actionable alteration in 55% (805/1474), however, only 45% (362/805) of these cases had a genomic variant annotated as actionable by expert curators. Further evaluation of these patients revealed that 66% (291/443) had a variant in a gene associated with biologic but not clinical evidence of actionability or a variant of unknown significance in a gene with at least one known actionable alteration. Of the cases annotated as actionable by experts, physicians identified an actionable alteration in 81% (362/445). In total, 13% (245/1932) of patients were enrolled to a genomically matched trial. CONCLUSION: Although physician and expert assessment differed, clinicians demonstrate substantial awareness of the genes associated with potential actionability and report using this knowledge to inform management in one in five patients. CLINICAL TRIAL NUMBER: NCT01775072.

Pathogenesis of chronic cluster headache and bouts: role of tryptamine, arginine metabolism and α1-agonists.

The aim of this study was to explore the possible role of tryptamine in the pathogenesis of chronic cluster headache along with that of adrenaline and noradrenaline (α-agonists) together with arginine metabolism in the origin of cluster bouts. Plasma levels of tyramine, tryptamine, serotonin, 5-hydroxyindolacetic acid, noradrenalin, adrenalin and the markers of arginine metabolism such as arginine, homoarginine, citrulline, ADMA and NMMA, were measured in 23 chronic cluster headache patients (10 chronic cluster ab initio and 13 transformed from episodic cluster) and 28 control subjects. The plasma levels of tyramine, tryptamine, noradrenalin and adrenalin were found several times higher in chronic cluster headache patients compared to controls, whereas the plasma levels of arginine, homoarginine and citrulline were significantly lower. No differences were found in the plasma levels of serotonin, 5-hydroxyindolacetic, ADMA and NMMA between chronic cluster headache patients and control subjects. These results provide support for a role of tryptamine in the pathogenesis of chronic cluster headache and, in particular, in the duration of the cluster bouts. In addition, the low levels of the nitric oxide substrates together with the high levels of noradrenalin and adrenalin suggest an activation of endothelial TAAR1 receptors followed by the release of nitric oxide in the circulation that may constitute the final step of the physiopathology of cluster crisis.

Biochemistry of primary headaches: role of tyrosine and tryptophan metabolism.

The pathogenesis of migraine as well as cluster headache (CH) is yet a debated question. In this review, we discuss the possible role of the of tyrosine and tryptophan metabolism in the pathogenesis of these primary headaches. These include the abnormalities in the synthesis of neurotransmitters: high level of DA, low level of NE and very elevated levels of octopamine and synephrine (neuromodulators) in plasma of episodic migraine without aura and CH patients. We hypothesize that the imbalance between the levels of neurotransmitters and elusive amines synthesis is due to a metabolic shift directing tyrosine toward an increased decarboxylase and reduced hydroxylase enzyme activities. The metabolic shift of the tyrosine is favored by a state of neuronal hyperexcitability and a reduced mitochondrial activity present in migraine. In addition we present biochemical studies performed in chronic migraine and chronic tension-type headache patients to verify if the same anomalies of the tyrosine and tryptophan metabolism are present in these primary headaches and, if so, their possible role in the chronicity process of CM and CTTH. The results show that important abnormalities of tyrosine metabolism are present only in CM patients (very high plasma levels of DA, NE and tryptamine). Tryptamine plasma levels were found significantly lower in both CM and CTTH patients. In view of this, we propose that migraine and, possibly, CH attacks derive from neurotransmitter and neuromodulator metabolic abnormalities in a hyperexcitable and hypoenergetic brain that spread from the frontal lobe, downstream, resulting in abnormally activated nuclei of the pain matrix. The low tryptamine plasma levels found in CM and CTTH patients suggest that these two primary chronic headaches are characterized by a common insufficient serotoninergic control of the pain threshold.

Lack of genotypephenotype correlation in congenital adrenal hyperplasia due to a CYP21A2-like gene.

CONTEXT: Congenital Adrenal Hyperplasia (CAH) due to 21-hydroxylase deficiency, encoded by CYP21A2 gene, is an autosomal recessive disorder. The CYP21A2 gene, localized in a genetic unit defined RCCX module, is considered one of the most polymorphic of human genes. OBJECTIVES: We considered new evidences about the presence of a RCCX trimodular haplotype with a CYP21A2-like gene to explain the lack of a genotype-phenotype correlation in individuals of two different families. DESIGN AND METHODS: To verify gene duplication we used Multiplex Ligation Probe-Dependent Amplifications (MLPA) and to confirm the presence of a CYP21A2-like gene downstream TNXA gene we used previously described amplification and restriction strategy followed by the sequencing of the CYP21A2 gene downstream TNXB gene. RESULTS: The amplification strategy and restriction analysis of CYP21A1P/CYP21A2-TNXA PCR product in association with MLPA assay and sequencing of CYP21A2 gene downstream TNXB were able to identify the presence of the CYP21A2-like gene in healthy subjects of the two families, wherein the direct sequencing of CYP21A2 gene showed genotypes correlated to pathological phenotypes. CONCLUSIONS: The strategy suggested is useful to facilitate molecular testing in CAH patients, considering the new evidence about possible different haplotypes.

Herbal therapy in migraine.

The use of herbal therapies is ancient and increasing worldwide. There is a growing body of evidence supporting the efficacy of various "complementary" and alternative medicine approaches in the management of headache disorders. Promising tools to treat migraine patients are herbal products. In particular constituents of Petasites hybridus, Tanacetum Parthenium and Ginkgo Biloba have shown antimigraine action in clinical studies. A miscellaneous of recreational drugs and other herbal remedies have been supposed to have a role in headache treatment but quality of clinical studies in this field is low and inconclusive. Further research is warranted in this area.

Usefulness of image guidance in the surgical treatment of petrous apex cholesterol granuloma.

The petrous apex is a pyramid-shaped structure, located medial to the inner ear and the intrapetrous segment of the internal carotid artery. Lesions of the petrous apex can be surgically treated through different surgical routes. Because of the important neurovascular structures located inside the temporal bone, anatomical 3D knowledge is paramount. For this reason, image-guided surgery could represent a useful tool. We report the case of a young woman who came to our observation for a trigeminal neuralgia due to a petrous apex cholesterol granuloma. The lesion was treated through the placement of a drainage tube via an infracochlear approach, with the aid of neuronavigation and intraoperative MRI. Preoperative CT scan images and intraoperative MRI images were fused for surgical planning. The accuracy of the neuronavigation system has proved to be good, and the safety of the procedure was enhanced. Therefore, neuronavigation and intraoperative MRI, though not available in all neurootological centres, should be considered useful tools in these challenging procedures.

Unmet needs and knowledge of postpartum contraception in Italian women.

PURPOSE OF INVESTIGATION: Clinic visits during pregnancy and puerperium provide a unique opportunity to counsel women on contraception practices. With the aim of evaluating postpartum contraceptive attitudes among urban women attending an antenatal care center and delivering in the same facility, a structured questionnaire was administered to assess desired and received information on contraception in the postpartum period. RESULTS: A total of 436 consecutive interviews were collected during the study period. Pregnancy was unplanned in 39% of the women interviewed. Overall, 269 women (61.7%) had decided to use a method of family planning during postpartum. Among the 112 women who stated they did not want to use a method during postpartum, almost 50% stated that they "did not think they needed it", due to a perceived lack of real risk. Of the 436 women interviewed, only 5.5 % women acknowledged that they had received information on contraceptive use. CONCLUSION: The present study indicates a need for ante- and postpartum counseling of women even in urban areas of Italy.

Ganglioglioma of the right lateral ventricle approached with neuronavigation and intraoperative DTI. Case report and literature review.

UNLABELLED: BACKGROUND AND STUDY OBJECT: We describe the case of a young patient treated for a ganglioglioma of the right lateral ventricle. The ganglioma was approached via a temporal route using neuronavigation. Such lesions, if confined to the ventricular system and, especially, to the lateral ventricle, are unusual. CASE REPORT: A 22-year-old male was admitted because of headache and seizures. Magnetic resonance imaging (MRI) revealed a neoplasm in the temporal horn of the right lateral ventricle. A CT scan demonstrated calcifications. After preoperative planning, the patient was scheduled for neuronavigated operation. A small temporal craniotomy was performed. Once the dura was opened, we acquired a volumetric intraoperative MRI with diffusion tensor imaging (DTI). The optic tract was visualized again on intraoperative DTI and the volumetric MRI was used to update the navigational data. RESULTS: The temporal corticotomy between the inferior and the middle temporal gyrus was guided by neuronavigation, keeping the surgical corridor in distance to the optic tract until the tumor was reached. After tumor resection, we repeated intraoperative MRI with DTI, which confirmed complete tumor removal and the patency of the optic pathway. Our protocol allowed us to reach the lesion via a minimally invasive approach with near real-time control of the integrity of the optic tract during surgery. DTI was acquired preoperatively and during surgery, avoiding inaccuracy due to brain shift. CONCLUSIONS: Intraoperative MRI with DTI allows to treat such lesions via minimally invasive approaches and to reduce operative morbidity due to fiber tract damage.
