[Cost-effectiveness analysis of fracture liaison services in Catalonia]

OBJECTIVE

To assess the cost-effectiveness of Fracture Liaison Service (FLS) compared to the standard of care for secondary prevention of fragility fractures form the perspective of the Catalan Health Service.

METHODS

Cost-utility assessment through a Markov model that simulated disease progression of a patients' cohort candidates to initiate antiosteoporotic treatment after a fragility fracture. A time horizon of 10 years and a 6-month duration per cycle was established. Clinical, economics and quality of life parameters were obtained from the literature and derived from four Catalan FLS. The Catalan Health Service perspective was adopted, considering direct health costs expressed in 2022 euros. A 3% discount rate was applied on costs and outcomes. Uncertainty was assessed through multiple sensitivity analyses.

RESULTS

Compared to the standard of care, FLS would promote antiosteoporotic initiation and persistence, reducing the incidence and mortality associated with subsequent fragility fractures. This incremental clinical benefit was estimated at 0.055 years and 0.112 quality-adjusted life years (QALYs) per patient. A higher cost (€1,073.79 per patient) was estimated, resulting into an incremental cost-utility ratio of €9,602.72 per QALYs gained. The sensitivity analyses performed were consistent, corroborating the robustness and conservative approach of the base-case.

CONCLUSIONS

The introduction of FLS for the secondary prevention of FF would represent a cost-effective strategy from the Catalan Health Service perspective.

Anorexia Nervosa and Gender Dysphoria: A Clinical Case

Introduction

Eating disorders (ED) and gender dysphoria (GD) are associated with a change in body perception. Therefore, body dissatisfaction plays a common and central role in these disorders. In GD, body image concerns are related to the features of the biological sex. In ED, body dissatisfaction comes from a distorted perception of weight and body shape and plays an important role in the development and maintenance of the psychopathology.

Objectives

To present and discuss the clinical case of a patient with a previous diagnosis of GD who presented with a clinical condition suggesting a restrictive anorexia nervosa (AN).

Methods

Patient´s clinical files consultation and literature review using Pubmed and the keywords: eating disorders and gender dysphoria.

Results

We present the case of a 25-year-old patient who was living in a shelter for victims of domestic violence and was admitted for severe restrictive AN. The patient was discharged after 40 days and medicated with sertraline, diazepam and olanzapine, as well as her previous medication (hormonal therapy): cyproterone, finasteride, estradiol, oxybutynin.

Conclusions

Although studies on this subject are still scarce, there has been some progress and the literature recognizes the coexistence of these conditions. However ED symptoms in patients with GD could have a different meaning: they may represent a dysfunctional coping strategy adopted to block features of the biological sex. Therefore health professionals may take a more holistic approach to body image. Additional studies will be necessary, allowing the establishment of cause-consequence interactions between weight loss and psychopathology related to GD.

The Co-occurrence Of Eating Disorders And Psychosis

Introduction

Several reviews have reported the incidence of schizophrenia in patients with eating disorders (ED) to be between 3–10% and the incidence of transient psychotic episodes to be 10–15%. On the other hand, anorexia nervosa appears to affect 1 to 4% of schizophrenia patients. Reports of psychosis and ED occurring in the same patient have led to various views as to the nature of the relationship between the two.

Objective

Analysis of the literature illustrated by different clinical cases in which appears to be a relationship between ED and psychosis.

Aims

Critical reflection about the hypothesis that could underlie the comorbidity of psychotic illness and ED.

Methods

Non-systematic review of a literature search using the keywords: eating disorders; psychosis; comorbidity.

Results

There is no consistent sequence in the co-occurrence of the two conditions – ED sometimes precede and sometimes follows the onset of psychosis. ED patients can develop psychotic symptoms, most frequently transient in the course of the disorder, while others are subsequently diagnosed with a chronic psychotic disorder. On the other hand, patients with a primary psychotic illness can develop an eating disorder. The connection between the two, however, remains speculative, considering the hypothesis that ED and psychosis can be entirely separate disorders that can, by chance, occur in the same person.

Conclusions

The area of comorbidity and overlapping symptoms in psychiatry requires more deep research. Despite evidence from case series, the comorbidity between ED and psychosis is poorly understood, and firm conclusions cannot be drawn from this analysis.

Adhesions to manufacturer's trademark on the surface of a posterior chamber lens

A case is reported in which posterior synechiae to the manufacturer's trademark on the surface of a Shearing intraocular lens were noted ten days after the implantation of the lens. After a short course of low-concentration miotic therapy, the adhesions were broken. We concluded that irregularities on the surface of the lens, such as a manufacturer's trademark, provide a focus for synechiae. We suggest that intraocular lens manufacturers refrain from providing such identification on their products.
