Alteration Ocular Motility in Retinitis Pigmentosa: Case-Control Study.

Purpose: To evaluate ocular motility (OM) disorders and strabismus in a sample of patients with retinitis pigmentosa (RP) and a control sample. Methods: In this cross-sectional retrospective analysis, we studied a sample of RP patients with a mean age of 48.74 years and an average visual acuity of 7/10 based on Snellen optotype and a sample of control patients with similar mean age (49 years [men], 47 years [women]) and sex and an average visual acuity of 9.9/10, with the aim of assessing correlations between alteration of OM and strabismus in RP patients based on age, high refractive defect, or severely impaired binocular vision. The examination followed a protocol of testing for anamnesis and best-corrected visual acuity, as well as a complete eye examination, corneal reflex, cover test, OM, Hess screen, and Lang test. Results: At the first orthoptic evaluation, 45.16% of patients showed strabismus, 41.93% exotropia (25% of cases intermittent), 3.22% esotropia, and 6.45% vertical deviation. Later evaluation showed strabismus in 25.80% of patients, exotropia in 19.35% (9.67% intermittent), esotropia in 3.22%, and vertical deviation in 3.22%. Assessment of eye motility study showed 51.6% overaction of the inferior oblique and hypofunction of the superior rectus, and 18% overaction of the lateral rectus and hypofunction of the medial rectus. According to our results, alterations in OM and strabismus in RP patients are not correlated with age or high refractive defect. Therefore, motility disorders and strabismus are attributed to a genetic factor to which men are more susceptible. Conclusion: The incidence of OM disorder was 77.42%, and strabismus was present in 45.16% of patients.

Effect of COVID-19 lockdown on refractive errors in Italian children aged 5-12 years: A multi-center retrospective study.

PURPOSE: to explore the potential consequences of the COVID-19 lockdown on the prevalence of myopia among Italian children aged 5-12 years. MATERIALS AND METHODS: retrospective multicenter study conducted in Italy. Population: children aged 5-12. Selection: random selection of children who received an eye exam between 2016 to 2021. Inclusion criteria: healthy children presenting for a routine eye exam. Exclusion criteria: presence of ocular comorbidities other than refractive error, such as blepharoptosis, media opacities, corneal or retinal dystrophies, strabismus, amblyopia, or concurrent therapy with atropine 0.01%. Outcome measure: age and spherical equivalent (SE) measured in diopters (D) in the right eye (RE) in cycloplegia. Statistical analysis: ANOVA test. RESULTS: total of 803 children. In the years prior to COVID-19, the mean SE ± SD of healthy age-school children was: 0.54 ± 1.49 D in 2016; 0.43 ± 1.84 D in 2017; 0.34 ± 1.41 D in 2018; 0.35 ± 1.75 D in 2019 (ANOVA, p = .659). In 2021, the mean SE changed to -0.08 ± 1.44 D (ANOVA, p = .005). Mean age was comparable in all groups (ANOVA, p = .307). The prevalence of myopes (SE ≤-0.5D) and hyperopes (SE ≥ 2D) was respectively 24.10% and 9.64% among children aged 60-96 months, and 63.86% and 6.02% among children aged 97-144 months. These values represent a statistically-significant increase in the number of myopes (Chi-square, p = .016) and decrease in the number of hyperopes (Chi-square, p = .001), as compared to previous years (.06 and.48 respectively). CONCLUSION: this retrospective study shows a statistically-significant decrease in the mean SE in children aged 5-12 in the year following the COVID-19 lockdown. The percentage of myopes has increased significantly, while the percentage of hyperopes has decreased. The lifestyle changes caused by the lockdown led children to spend more time on near-work activities and digital devices, and less time outdoors. These are known risk factors for the development and progression of myopia. Studies in different countries are encouraged.

Applications for social security benefits related to diabetes in the working age in Italy between 2009 and 2019: a nationwide retrospective cohort study.

OBJECTIVES: The aim of this study is to estimate the average number of claims for social security benefits from workers with diabetes-related disability. DESIGN: Nationwide retrospective cohort study. SETTING: The database of the Italian Social Security Institute (INPS) was used to analyse the trends and the breakdown of all claims for social security benefit with diabetes as primary diagnosis from 2009 to 2019. PARTICIPANTS: We selected all the applications with the 250.xx International Classification of Diseases, Ninth Revision-CM diagnosis code from 2009 to 2019. PRIMARY AND SECONDARY OUTCOME MEASURES: The ratio between accepted or rejected claims for both ordinary incapacity benefit (OIB) and disability pension (DP) and total submitted claims over a 10-year period was computed. RESULTS: From 2009 to 2019, 40 800 applications for social security benefits were filed with diabetes as the principal diagnosis, with an annual increase of 30% per year. Throughout the study decade, there was a higher rate of rejected (67.2%) than accepted (32.8%) applications. Among the accepted requests, most of them (30.7%) were recognised as OIB and the remaining 2.1% were recognised as DP. When related to the total number of claims presented per year, there was a 8.8% decrease of rejected applications, associated with a 20.6% increase of overall acceptance rate. In terms of time trends, the overall rise of submitted requests from 2009 to 2019 resulted in an increase in both rejected (+18%) and accepted (+61% for OIB, +11% for DP) applications. The higher rate of accepted requests was for workers aged 51-60 years, with 52% of admitted applications. CONCLUSIONS: Between 2009 and 2019, the number of applications for social security benefits due to diabetes in Italy increased significantly, and so did the number of applications approved, mainly represented by the OIBs.

Health and Economic Impact of Atrial Fibrillation of Workers in Italy: Social Security Benefits.

BACKGROUND: The aim of this research was to analyze trends in social security applications in Italy as a result of the onset of atrial fibrillation, analyzing data pertaining to the classification of professions and assessing the economic impact on the social security system. METHODS: We analyzed all applications for invalidity allowances and invalidity pensions throughout Italy over a 10-year period from 01.01.2009 to 31.12.2019, giving specific attention to all reports indicating atrial fibrillation as the principal diagnosis (Cod. ICD-9-CM 427.31). We then extracted the relative expenditure data for said benefits. The results of all analyses have been collated in tables. RESULTS: Over the period in question, a total of 3468 applications for assistance were filed throughout Italy indicating a diagnosis of atrial fibrillation, of which 58% were rejected, 41% qualified for an invalidity allowance, and only 1.1% qualified for a pension. On average, every year, 1100 workers received social security benefits as a result of a diagnosis of atrial fibrillation, which equates to an average annual expenditure of EUR 10 million. A comparison of the data from the first observation year (2009) with data from the last (2019) shows a rising trend in the number of beneficiaries and consequently in expenses. CONCLUSIONS: The social security assistance provided by the Italian government by means of the National Institute of Social Security is fundamental to social cohesion and to those who are either permanently disabled from working or those with a significantly diminished earning capacity. This assistance is associated with a significant financial cost, which requires careful monitoring.

An Analysis of the Social and Economic Costs of Breast Cancer in Italy.

BACKGROUND: Breast cancer is the most prevalent cancer affecting women and it represents an important economic burden. The aim of this study was to estimate the socio-economic burden of breast cancer (BC) in Italy both from the National Health Service (NHS) and the government perspectives (costs borne by the social security system). METHODS: The economic analysis was based on the costs incurred by the NHS from 2008 to 2016 (direct costs related to hospitalizations) and by the National Social Security Institute (INPS) from 2009 to 2015 (costs of social security benefits) for patients with breast cancer. The analysis was based on the Hospital Information System (HIS) and Disability Insurance Awards databases. For both databases, patients affected by a malignant neoplasm of the female breast, carcinoma in situ, or secondary malignant neoplasm of the breast were considered. RESULTS: Results show that more than 75,000 women were hospitalized for breast cancer every year, with an overall cost for hospitalization of about €300 million per year. From the Social Security analysis, a number of 29,000 beneficiaries each year was estimated. Considering per patient social costs, breast cancer at the primary stage cost €8828 per year, while secondary neoplasms cost €9780, with an average total economic burden of €257 million per year. CONCLUSIONS: This analysis focused on the economic impact of breast cancer in Italy, showing that an advanced stage of the disease was associated with a higher cost.

Utility of Ocular Motility Tests in Orbital Floor Fractures with Muscle Entrapment That is Not Detected on Computed Tomography.

PURPOSE: Determine the usefulness of ocular motility testing to detect the presence of muscle entrapment. MATERIALS AND METHODS: Cross-sectional study of patients with symptoms of diplopia secondary to facial trauma. Inclusion criteria: age between 20 and 80 years; symptoms of diplopia following facial trauma; presence of orbital floor fracture confirmed radiologically; presence of muscle entrapment confirmed at the time of surgery; best-corrected visual acuity of 0.6 or more. Exclusion criteria: muscle entrapment visible on computed tomography; candidate for immediate surgical correction; prior history of strabismus surgery. Outcome measures: Abnormal Head Position (AHP), Hirschberg Corneal Reflexes (CR), Cover/Uncover and Alternating Cover Test, Hertel exophthalmometry, Near Point of Convergence (NPC), Kestenbaum Limbus test, Red Filter test, and Hess screen test. RESULTS: Forty-six subjects (38 males, 8 females, mean age 27 ± 3.3 SD years). Pre-operative assessment: forty-six (100%) reported diplopia on the Red Filter test and showed some degree of abnormality on the Hess Screen test. Forty-two (91%) showed AHP. Forty-one (89%) had exophthalmometry values that differed 2 mm or more between the two eyes and insufficient NPC. Thirty-two (69.6%) showed deficits of 3 mm or more on the Kestenbaum Limbus test. Sixteen (35%) had abnormal Hirschberg corneal reflexes. Eleven (24%) demonstrated constant or intermittent strabismus. CONCLUSION: Ocular motility testing can differentiate non-invasively, pre-operatively, and cost-effectively the presence of muscle entrapment even when this is not visible on computed tomography.

Economic Impact of Schizophrenia from a Hospital and Social Security System Perspective in Italy.

BACKGROUND: Schizophrenia is one of the mental disorders with the highest economic and social costs, with an important burden on patients, caregivers, and society. OBJECTIVE: The objective of this study was to estimate the direct and social security costs of schizophrenia in Italy. As far as direct costs are concerned, those related to hospitalizations and pharmaceutical expenditure have been analyzed, while disability benefits (DBs) and incapacity pensions (IPs) have been considered for the social security costs. METHODS: In order to provide annual economic burden of schizophrenia using the real-world data, we analyzed the main regional and national databases related to hospitalizations and pharmaceuticals. Hospitalizations have been analyzed considering the Hospital Information System, which collects all the information regarding hospital discharges from all public and private hospitals (psychiatric wards or residential facilities have not been considered). Hospitalizations with a discharge date between 2009 and 2016, and with a primary or secondary diagnosis of schizophrenia (International Classification of Diseases, Ninth Revision, Clinical Modification [ICD-9-CM] code 295.xx) were selected. Hospital costs have been estimated considering the national tariffs associated with each selected hospitalization. In addition, using the same inclusion criteria, the average DBs (for workers with reduced working capacity) and IPs (for workers without working capacity) provided each year have been analyzed from the social security benefit applications database. The estimate of pharmaceutical expenditure was prepared based on the OsMed 2018 Report (Italian Medicines Agency, latest issue 18 July 2019). A one-way deterministic sensitivity analysis was conducted to examine the robustness of the results. RESULTS: In Italy from 2009 to 2016, schizophrenia had an important economic impact from a social perspective. On average, 13,800 patients were hospitalized, with an average of 2.98 hospitalizations per patient. From a National Health Service (NHS) perspective and with specific reference to hospitalizations, the annual economic burden was €101.4 million, with an average cost per patient of €7338. On the other hand, pharmaceutical expenditure amounts to over €147 million each year, while residential, semi-residential, and specialist facilities amount to approximately €1 billion. Again, schizophrenia led to approximately 15,000 recipients of social security benefits (DBs and IPs) yearly from 2009 to 2015, with an average annual expenditure of €160.1 million (average cost per patient = €10,675). CONCLUSIONS: Our study estimates an economic burden of schizophrenia of €1250 million per year in direct costs, of which 20% is related to hospitalizations and pharmaceutical expenditure. With regard to social security benefits, an average annual expenditure of €160.1 million was calculated (average cost per patient = €10,675).

Effectiveness of 0.1% topical salicylic acid on blepharoconjunctivitis affecting glaucoma patients treated with topical prostaglandin analogues: a prospective randomized trial.

AIM: To evaluate the efficacy of 0.1% topical salicylic acid (TSA) to treat iatrogenic chronic blepharoconjunctivitis in patients with primary open angle glaucoma (POAG), treated with topical prostaglandin analogues (TPAs). METHODS: Totally 60 patients were randomly distributed into 3 equal size groups, two of which treated with 0.1% TSA (OMKASA®) and 0.1% topical clobetasone butyrate (TCB; VISUCLOBEN®) respectively, and one consisting of untreated controls. The parameters taken into account at baseline (T0) and after 30d (T1) of therapy were: conjunctival hyperemia, lacrimal function tests [Schirmer I test and break up time (BUT)] and intraocular pressure (IOP). RESULTS: Conjunctival hyperemia showed a substantial improvement in both treated groups (P<0.001) but not among controls. Similarly, lacrimal function tests displayed an improvement of Schirmer I test in both treated groups (P<0.05) and an extension of BUT only in the group treated with 0.1% TSA (P<0.05). The IOP increase was statistically significant only in those patients treated with 0.1% TCB (P<0.001). CONCLUSION: The 0.1% TSA has proved to be an effective anti-inflammatory treatment of blepharoconjunctivitis affecting glaucoma patients on therapy with TPAs, leading to a sizeable decrease of inflammation as well as both quantitative and qualitative improvement of tear film. Furthermore, differently from 0.1% TCB, it does not induce any significant IOP increase.

Eye Motility Alterations in Retinitis Pigmentosa.

Purpose. We evaluated a sample of individuals with retinitis pigmentosa (RP) with the aim of assessing the presence or absence of ocular motility (OM) disorders. Materials and Methods. We included 23 out of the 25 individuals from the sample (9 females and 14 males) with an average visual acuity of 6/10. Results. The cover test about the vertical deviation in near distance showed an r/l in 3.45% and an l/r in 6.9%. The assessment of OM showed that 39.1% of the sample had a severe hyperfunction of the IO of the right eye and a severe hyperfunction (34.5%) of the SO of the left eye; 21.8% had a moderate hypofunction of right SO with a moderate percentage of hypofunction of 17.5% for the SO of the left eye; 30.5%, however, showed a serious hypofunction of the SR of both eyes; 21.7% of the sample showed a hyperfunction in both eyes of the IR. Conclusion. This alteration, however, is not attributable to either a high refractive defect (medium-low myopia: -1 diopter ±3 SD) or to a severely impaired binocular vision (visual acuity, motor fusion, and stereopsis are normal or within a range of values commonly accepted). Therefore, the disorders of OM lead to a genetic origin.
