Broadening the ocular phenotypic spectrum of ultra-rare BRPF1 variants: report of two cases

INTRODUCTION

BRPF1 gene on 3p26-p25 encodes a protein involved in epigenetic regulation, through interaction with histone H3 lysine acetyltransferases KAT6A and KAT6B of the MYST family. Heterozygous pathogenic variants in BRPF1 gene are associated with Intellectual Developmental Disorder with Dysmorphic Facies and Ptosis (IDDDFP), characterized by global developmental delay, intellectual disability, language delay, and dysmorphic facial features. The reported ocular involvement includes strabismus, amblyopia, and refraction errors. This report describes a novel ocular finding in patients affected by variants in the BRPF1 gene.

METHODS

We performed exome sequencing and deep ocular phenotyping in two unrelated patients (P1, P2) with mild intellectual disability, ptosis, and typical facies.

RESULTS

Interestingly, P1 had a Chiari Malformation type I and a subclinical optic neuropathy, which could not be explained by variations in other genes. Having detected a peculiar ocular phenotype in P1, we suggested optical coherence tomography (OCT) for P2; such an exam also detected bilateral subclinical optic neuropathy in this case.

DISCUSSION

To date, only a few patients with BRPF1 variants have been described, and none were reported to have optic neuropathy. Since subclinical optic nerve alterations can go easily undetected, our experience highlights the importance of a more detailed ophthalmologic evaluation in patients with BRPF1 variant.

Efficacy of a Cationic Emulsion of Cyclosporine in Moderate Vernal Keratoconjunctivitis

PURPOSE

The aim of this study was to demonstrate the efficacy of cyclosporine A 0.1% cationic emulsion (CsA CE) eye drops 4 times a day in pediatric patients affected by a moderate form of vernal keratoconjunctivitis (VKC).

METHODS

This was a prospective study of pediatric patients, aged 5-16 years, with an active moderate form of VKC who were poor responders to topical antihistamines treatment and were treated 4 times a day with CsA CE. The clinical signs were graded for analysis as follows: hyperemia, tarsal papillae, and limbal papillae.

RESULTS

Twenty-eight patients (22 males and 6 females) with a minimum follow-up period of 3 months were included in the analysis. Statistical analysis excluded tarsal papillae because of the very low baseline value. The clinical score of hyperemia and limbal papillae improved from the first evaluation and was maintained over the follow-up. No side effects were noted.

CONCLUSION

CsA CE has been proposed as a treatment for severe forms of VKC. This study has shown that administration 4 times a day is also effective in the treatment of moderate forms of VKC in children.

Microperimetry assessment in foveal hypoplasia: functional results in a series of pediatric patients

OBJECTIVE

To study the relationships of functional and morphologic retinal parameters in a series of pediatric patients with varying degrees of foveal hypoplasia (FH).

DESIGN

Monocentric observational retrospective study.

PARTICIPANTS

Among 21 pediatric patients, 16 met inclusion criteria, having FH confirmed with spectral-domain optical coherence tomography (SD-OCT) scan METHODS: Data were analyzed retrospectively. Patients able to undergo macular microperimetry (MP) and SD-OCT examinations were included in the analysis. MP and SD-OCT outcomes were compared with FH grading and best-corrected visual acuity (BCVA) using Pearson's correlation.

RESULTS

Thirty-one eyes from 16 patients (mean age 12.4 years) with different degrees of FH were analyzed. Two patients had grade 1, 7 had grade 2, 5 had grade 3, and 2 had grade 4 FH. Clinical nystagmus was present in 8 patients. The correlation between BCVA and SD-OCT data (-0.31) was lower than that found between BCVA and nystagmus (0.64), that for fixation index P1 (-0.60), as well as that for macular sensitivity (-0.63).

CONCLUSIONS

Although limited by the small sample, our study confirms the feasibility of automated MP evaluation in pediatric patients with FH. The added value of this work is the provision of data on relationships between anatomic and functional macular measurements acquired with SD-OCT, MP, and BCVA in eyes with various degrees of FH. Larger prospective studies are necessary to confirm these results.

The New Era of Therapeutic Strategies for the Treatment of Retinitis Pigmentosa: A Narrative Review of Pathomolecular Mechanisms for the Development of Cell-Based Therapies

Retinitis pigmentosa, defined more properly as cone-rod dystrophy, is a paradigm of inherited diffuse retinal dystrophies, one of the rare diseases with the highest prevalence in the worldwide population and one of the main causes of low vision in the pediatric and elderly age groups. Advancements in and the understanding of molecular biology and gene-editing technologies have raised interest in laying the foundation for new therapeutic strategies for rare diseases. As a consequence, new possibilities for clinicians and patients are arising due to the feasibility of treating such a devastating disorder, reducing its complications. The scope of this review focuses on the pathomolecular mechanisms underlying RP better to understand the prospects of its treatment using innovative approaches.

Optic nerve involvement in CACNA1F-related disease: observations from a multicentric case series

BACKGROUND

Congenital Stationary Night Blindness (CSNB) constitutes a group of non-progressive retinal disorders characterized by disturbances in scotopic vision and/or by a delay in adaptation to darkness, as well as by low visual acuity, myopia, nystagmus, and strabismus. Color vision and fundus appearance tend to be normal. To date, several CACNA1F gene variants have been linked to a CSNB phenotype but only few reports have focused on the optic nerve in this disease.

MATERIALS AND METHODS

Twelve patients underwent standard ophthalmological and genetic evaluation including spectral domain optical coherence tomography (SD-OCT), full-field electroretinography (ffERG), kinetic perimetry, fundus photography, magnetic resonance imaging (MRI), and next-generation sequencing (NGS). Bilateral thinning of the peripapillary nerve fiber layer (pRNFL) and the ganglion cell complex (GCC) supported involvement of the optic nerves. MRI, when available, was assessed for gross intracranial optic pathway abnormalities.

RESULTS

All patients were shown to carry pathogenic variants in the CACNA1F gene, and all showed signs of optic nerve involvement. All patients showed a certain degree of myopic refractive error. Low average pRNFL thickness was evident in all patients. In three of them, pRNFL thickness was evaluated longitudinally and was proven to be stable over time. MRI imaging was unremarkable in all cases.

CONCLUSION

Our data support the hypothesis that CACNA1F could be related to early-onset or congenital optic nerve involvement without any signs of a progressive optic neuropathy. Even though additional data from larger cohorts and longer follow-up periods are needed to further support and confirm our findings, there is a clear significance to our findings in the preparation for future CACNA1F gene therapy trials.

X-linked retinoschisis: mutation spectrum and genotype-phenotype relationship in an Italian pediatric cohort

BACKGROUND

X-linked juvenile retinoschisis (×LRS) is an X-linked vitreoretinal degenerative disease that consists of variable phenotypes ranging from severe early-onset defects to subtle abnormalities diagnosed in elderly patients. XLRS is caused by a loss of function of the protein Retinoschisin (RS1), which is essential to preserve retinal integrity and function of photoreceptor-bipolar synapse. The literature data so far mostly agree on the absence of a clear genotype-phenotype correlation in XLRS. We reviewed clinical and molecular characteristics of a cohort of Italian pediatric XLRS patients to assess the presence of a correlation between genotype and phenotype severity.

MATERIALS AND METHODS

We retrospectively examined clinical and genetic features of a cohort of 27 XLRS patients. In this study we included patients with a diagnosis of XLRS confirmed by fundus photography, spectral domain optical coherence tomography, and molecular analysis and with an onset of less than 10 years of age. We sorted RS1 variants according to their effect of RS1 structure and function in three separate groups.

RESULTS

According to previous studies, we did not observe a conclusive genotype-phenotype correlation in our cohort; nevertheless, we noticed that patients harboring RS1 variants leading to RS1-secreted mutants show a more homogeneous phenotype, with an overall good visual acuity, compared to the other two groups.

CONCLUSIONS

Our data support the hypothesis that secretion profile of RS1 could influence the severity of the phenotype. More extensive and functional studies are needed to acquire notions in view of the opportunity of gene replacement therapy for XLRS patients.

Impact of a multidisciplinary intervention on Mediterranean diet adherence and cardiovascular health

Background

Cardiovascular diseases represent a significant public health issue, and the promotion of healthy lifestyles plays a major role in their prevention. Good adherence to the Mediterranean diet has a protective effect on cardiovascular health and may reduce the risk of developing cardiovascular disease. Our prospective study aimed to evaluate the impact of educational lifestyle interventions on cardiovascular risk parameters and the improvement in adherence to the Mediterranean diet of the involved population.

Methods

Participants have been recruited by General Practitioners in Torresina neighborhood in Rome. From December 2018 to June 2020, 41 patients were involved in nutritional, psychological, and physical activity meetings by a multidisciplinary team of healthcare professionals. In particular, a nutritionist provided information to patients on balanced nutrition, considering the Mediterranean diet as a dietary model. Information on lifestyle, dietary habits and physical activity, anthropometric data and laboratory measurements were collected at baseline and after 12 months. The variations of the evaluated parameters were analyzed by paired t-test e Wilcoxon signed-rank test.

Results

The analysis showed statistically significant decreases in weight (p = 0.03) and BMI (p = 0.02), as well as in systolic (p < 0.001) and diastolic (p = 0.001) blood pressure and in total (p = 0.02) and LDL (p = 0.01) cholesterol level. Results also showed an improvement in the adherence to the Mediterranean diet (p = 0.001): the frequency of consumption of fruits and vegetables, legumes, cereals and fish has increased significantly, while the consumption of meat, milk and dairy products and alcohol decreased.

Conclusions

This study highlights that a multidisciplinary educational program can be effective in improving healthy habits and in reducing cardiovascular risk factors, supporting its implementation in primary prevention at the community level.

Key messages

• Promoting healthy lifestyle through primary prevention and health promotion actions is critical to reduce the onset of cardiovascular diseases.

• A population-based multidisciplinary educational intervention may be effective in improving adherence to a healthy, balanced diet and decreasing cardiovascular risk factors.

Flu shot in the era of COVID-19 vaccination: findings from a research hospital of Rome

 

Influenza represents a major burden for public health. Healthcare workers (HCWs) are a priority target group for flu vaccination. During the COVID-19 pandemic, when SARS-CoV-2 vaccines were not yet available, susceptibility to influenza vaccination especially by HCWs increased. The aim of this study is to analyze the flu vaccination coverage among HCWs and to study which factors affected their adherence given the concomitant COVID-19 vaccination. The retrospective study was conducted in an Italian research hospital from October 2021 to January 2022. A total of 7,048 individuals was included. Age class, gender and job category variables were analyzed. Statistically significant differences among groups were tested through χ2 test. Univariate and multivariate analyses (p < 0,005) were performed to assess differences towards vaccination attitude. The flu vaccination coverage rate was 24.6%. Among the selected job categories, 29.8% of physicians, 19.9% of nurses and 19.7% of other HCWs were vaccinated with a statistically significant decrease (p < 0.001) across all categories respect with the last campaign. The findings of the logistic regression depicted that the 40-59 years old age class, compared with the youngest age class (OR 1.30, 95% CI 1.12-1.43) as well as being physician (OR 2.79, 95% CI 1.87-3.41) with the respect to being nurses, had a higher adherence to vaccination. Interestingly, being male, is associated with a statistically significant reduction (OR 0.71, 95% CI 0.59-0.87) in vaccination uptake. Study findings showed a several decline in the flu vaccination coverage comparing with previous campaigns, probably due to the concomitant administration of the booster dose against SARS-CoV-2. This alarm should not be underestimated and requires timely and innovative organizational approaches (i.e., combined vaccine). Further studies are needed to analyze the reasons for this poor adhesion and the strategies to be adopted to increase the awareness of the HCWs.

Key messages

• Reaching high coverage rates and restore a positive trend for the future campaign for flu vaccination it is essential strategy to protect HCWs themselves, their patients and the hospital community.

• Decision-makers should implement consistent communication strategies to lessen vaccine hesitancy among HCWs.

An interdisciplinary intervention for health prevention and promotion in a Roman neighborhood

 

Influencing behavioral patterns through primary prevention, possibly addressing more risk factors at a time, is the most effective means to tackle cardiovascular diseases. Many interdisciplinary prevention activities have been coordinated by community nurses outside of specialist centers, resulting in a more effective control of risk factors. Our study aims at describing the impact of an 18-month prevention and promotion, interdisciplinary intervention on lifestyle habits and cardiovascular risk. From December 2018 to May 2020, patients were recruited by 4 General Practitioners (GPs) in the Roman neighborhood of Torresina and received nutritional, physical and psychological counselling to learn healthy lifestyles. Until May 2020 patients had to self-manage their new healthy habits, but during this phase the SARS-CoV-2 pandemic broke out. Patients were assessed at baseline, 6, 12 and 18 months by a nutritionist, a physiotherapist, a psychologist, the 4 GPs and community nurses, and the cardiovascular risk score (CRS) was estimated at every examination. 76 patients were included, with a mean age of 54,6 years. Mean CRS showed a significant reduction between baseline and 12 months (from 4.9 to 3.8, p < 0.001), but this trend was not maintained at 18 months. As for variables included in the calculation of the cardiovascular risk score, both total cholesterol and systolic blood pressure significantly decreased at 6 months of follow up (respectively, from 211.1 to 192 (p < 0.001) and from 133.1 to 123.1(p < 0.001)). Nontheless, the reduction was maintained in the remaining points in time only for systolic blood pressure. Our interdisciplinary educational intervention in a primary care setting resulted in a CRS improvement at 12 months, but this changes where not maintained at 18 months. Community nurses were facilitators in improving health outcomes and patient's satisfaction in the described primary care setting.

Optical Coherence Tomography Significance in Managing Early Onset of Optic Pathway Gliomas in Children Younger than 5 Years of Age—A Retrospective Study

We aimed to investigate the significance of optical coherence tomography (SD-OCT) in managing pediatric optic pathway gliomas (OPGs) in children younger than 5 years of age. A retrospective monocentric study was conducted. SD-OCT scans were obtained using the handheld iVue system to assess peripapillary retinal nerve fibre layer (pRNFL) thickness at three time points: baseline (OCT1), end of treatment (OCT2), and at last follow-up (OCT3). We compared the median value of pRNFL (and interquartile range—IQR) at different follow-up times and in different sub-groups (stable disease—SD, partial response—PR, and progression disease—PD). Thirteen children younger than 5 years of age were included. The Median follow-up time was 3.9 years (IQR 1.2). Six patients showed a pRNFL change of more than 10% during follow-up. Seven patients showed PD during follow-up. Median pRNFL at baseline was 81.5 µm (IQR 31.5); median pRNFL at the end of treatment was 73 µm (IQR 33); median pRNFL at last follow-up was 72 µm (IQR 38.5). The mean pRNFL at baseline was significantly lower than the mean normative values. Only subjects with PD showed pRNFL change close to statistical significance. This study confirms the role of SD-OCT in managing OPGs for therapeutic decisions and strategy planning of visual rehabilitation.

Acute Rejection Following COVID-19 Vaccination in Penetrating Keratoplasty in a Young Male - A Case Report and Review of Literature

PURPOSE

To report a case of a boy with acute keratoplasty rejection manifesting 12 days after receiving BNT162b2 messenger RNA (mRNA) vaccine for COVID-19.

STUDY DESIGN

A case report.

RESULTS

A 15-year-old boy with a history of penetrating keratoplasty due to acanthamoeba keratitis developed corneal decompensation 12 days after BNT162b2 messenger RNA vaccine for COVID-19 disease. One-week treatment with topical Dexamethasone 2% eye drops resulted in a complete resolution of corneal edema.

CONCLUSIONS

This case suggests that BNT162b2 messenger RNA (mRNA) vaccine can be associated with acute keratoplasty rejection in children, which responds completely to topical steroids. Ophthalmologists should be aware of this risk of cornea decompensation after COVID-19 vaccine in children who received a cornea transplant.

Treatment of Inherited Retinal Dystrophies with Somatic Cell Therapy Medicinal Product: A Review

Inherited retinal dystrophies and retinal degenerations related to more common diseases (i.e., age-related macular dystrophy) are a major issue and one of the main causes of low vision in pediatric and elderly age groups. Advancement and understanding in molecular biology and the possibilities raised by gene-editing techniques opened a new era for clinicians and patients due to feasible possibilities of treating disabling diseases and the reduction in their complications burden. The scope of this review is to focus on the state-of-the-art in somatic cell therapy medicinal products as the basis of new insights and possibilities to use this approach to treat rare eye diseases.

Coping Styles in the SARS-CoV-2 national lockdown: impact on behaviors for cardiovascular prevention

Background

Coping styles are the ways in which people deal with different stressor situations. Coping strategies can be categorized into three types: task-oriented, emotion-oriented, and avoidance-oriented. Several studies showed a strong relationship between coping styles and cardiovascular diseases. The aim of the study was to evaluate how much the SARS-CoV-2 national lockdown has impacted the coping strategies on behaviors for cardiovascular prevention.

Methods

62 participants from Rome were recruited to assess the impact of prevention and promotion of health on Individual Cardiovascular Risk. The Coping Inventory to Stressful Situations (CISS, Endler & Parker, 1990) is a self-report questionnaire that measures the three strategies of coping. Behaviors dealing with cardiovascular prevention were evaluated at the beginning of the observation period, and after 6, 12, and 18 months. During 12 (February 2020) and 18 months (July 2020) the SARS-CoV-2 national lockdown enabled us to inquire into coping strategies in stressful situations and cardiovascular risk factors.

Results

The Pearson correlation analysis was used to assess the existence of a correlation between coping strategies and the variation of cardiovascular risk factors and alcohol consumption at 12 and 18 months. Interestingly, results showed relations between Emotional-oriented (r = 0.26 p &lt; 0.05) and Task-oriented (r = -0.33 p &lt; 0.01) coping styles and Differential Cardiovascular Risk Reduction (DCRR). Furthermore, a positive relation between Task-oriented (r = 0.34 p &lt; 0.01) coping style and Differential Alcohol Consumption (DAC) was observed.

Conclusions

We found that the DCRR relates to the Emotional- and Task-oriented coping styles, while DAC is associated with the Task-oriented coping style. The strength of our study consists in the territorial and multidisciplinary dimension of the project, the main critical issue is represented by the small size of the patient sample.

Key messages

A relationship can be described between Differential Cardiovascular Risk Reduction and Emotional- and Task-oriented coping styles. There is a relationship between Differential Alcohol Consumption and the Task-oriented coping style.

From infections to preventive actions monitoring in health facilities: an experience on MDROs

 

Healthcare-Associated Infections (HAIs) and Antimicrobial Resistance (AMR) involve high costs both in health and economic terms for patients and health systems. Implementing Infection Prevention and Control (IPC) programs is critical to decrease infectious agents' transmission in healthcare settings. The aim of this study is to assess if the monitoring of Contact Precautions could decrease the incidence of Multi-Drug Resistant Organisms (MRDOs) infections. This pilot study was conducted in a teaching hospital in Rome. A checklist of 16 items was developed to assess the compliance to Contact Precautions in 11 hospital wards in which MRDOs were detected between November and December 2020. It was administered on-site both interviewing healthcare professionals and through direct observation. A paired t-test with α = 5% was used to compare the number of alert organisms in the first quarter of 2020 respect to the first quarter of 2021 before and after implementing the surveillance checklist. A total of 30 checklists were analyzed. The rate of compliance to Contact Precautions was high for the proper use of personal protective equipment (100%), the intensified room cleaning (100%) and the presence of isolation mark (100%), while it was low for the active screening of contacts (53%). Mean MDROs infections rate decreased from 4.94 to 4.37 for every 1000 hospitalization day, with an average decrease of 0.57. However, the paired t-test showed that there was no statistically significant difference between the mean number of MDROs infections before and after the implementation of the checklist (p > 0.05). Despite the good adherence to IPC program, the low infection rate decrease, is probably due to the impact of COVID-19 on the HAIs surveillance and prevention practices. Even if the check-list administration could be a useful tool to reduce MDROs infections, it should be associated to other prevention strategies during the COVID-19 pandemic in order to achieve a successful outcome.

Key messages

Preventing Healthcare-Associated Infections represents a priority public health challenge in order to improve patient safety and health system economic sustainability.

The COVID-19 pandemic has shown that healthcare facilities should enhance efforts in their IPC programs to reduce Healthcare-Associated Infections.

Italian health workers’ knowledge, attitudes and behaviours towards COVID-19 vaccination

Background

Vaccine hesitancy is the reluctance or refusal to be vaccinated. While it has been widely studied for various contagious diseases, there is still a lack of knowledge about this phenomenon for COVID-19, especially if health workers' hesitancy is considered.

Methods

An extensive review of the literature was conducted to identify the main determinants of vaccine hesitancy in health workers, as well as to find already validated surveys to evaluate the knowledge, attitudes and behaviors (KAB) of health workers towards vaccination, both in general and with specific regard to COVID-19. Building on the available information, a new survey was developed to assess the KAB of Italian health care workers towards COVID-19 vaccination after validation with a pilot study in a diverse sample of 30 Italian health workers.

Results

A new survey was validated to assess the KAB of health workers towards COVID-19 vaccination in Italian health workers. The survey requires about 6 minutes to complete and is composed of 30 questions, investigating different domains: socio-demographic and professional characteristics (6); health status (2); attitudes (11); behaviors (6); knowledge (4). The survey will be administered to a representative sample of at least 385 Italian health workers through the web platform SurveyMonkey in the period June-September 2021. Preliminary results will be available by the end of October 2021.

Conclusions

By analyzing KAB towards COVID-19 vaccination with a new tool, the magnitude and determinants of health worker's COVID-19 vaccine hesitancy will be evaluated to understand how to improve health workers' perception towards COVID-19 vaccination and, consequently, foster their positive influence on the general population.

Key messages

We explore the knowledge, attitudes and behaviors towards COVID-19 vaccination in all categories of health workers operating on the Italian territory to understand the reasons of vaccine hesitancy.

Understanding the determinants of COVID-19 vaccine hesitancy in Italian health workers is necessary given their influence on the perception of the general population in Italy.

The efficacy of biofeedback visual rehabilitation therapy in patients with infantile nystagmus syndrome: A retrospective study

OBJECTIVE

To report fixation stability changes in patients with different forms of infantile nystagmus syndrome (INS), who have undergone a visual rehabilitation through biofeedback fixation training (BFT) with microperimetry (MP).

DESIGN

Retrospective study.

METHODS

Patients 6 to 12 years-old with INS who performed BFT with MP. Initially 10 once-weekly followed by eight twice-weekly sessions of BFT during a minimum of 6 months period were performed. Visual acuity (VA) and MP fixation stability indices were analyzed, including displacement from fixation point (P1, P2) and percentage of retinal loci used during fixation attempt (BCEA 63% and 95%). Statistical analysis was conducted at baseline (BL), 10 weeks (W10) and 6 months (M6).

RESULTS

Twelve patients (mean age 8.9 years.) with INS completed the whole training session. All patients showed significant improvement in the mean BCEA fixation area (deg²): For BCEA@95% BL was 78.0, 46.1 at W10, and 27.4 at M6 (p-value = 0.004). For BCEA@63% BL was 27.3, 15.4 in W10, and 9.17 at M6 (p = 0.01). The ANOVA test for the FS indices of P1 and P2, as well as for BCVA showed no significant difference when compared at the same intervals.

CONCLUSION

Fixation stability (FS) indices of BCEAs (63% and 95%) improved at W10 and M6, while P1 and P2 showed significant improvement at W10 but not at M6, probably because BCEA involves a much larger area than P1 and P2. VA did not show significant improvement at any time point.

Ultrathin Descemet stripping automated endothelial keratoplasty versus Descemet membrane endothelial keratoplasty: a fellow-eye comparison

Background

To compare the visual outcome and patients’ satisfaction after ultrathin Descemet stripping automated endothelial keratoplasty (UT-DSAEK) and Descemet membrane endothelial keratoplasty (DMEK) performed on fellow eyes of the same patients.

Methods

In this retrospective study, the records of 18 pseudophakic patients affected by Fuchs endothelial dystrophy who underwent DMEK in one eye and UT-DSAEK in the fellow eye were reviewed. Best corrected visual acuity (BCVA), corneal pachymetry, keratometry, corneal aberrations, photopic and mesopic contrast sensitivity, and endothelial cell counts measured 12 months after surgery in either eye were analyzed and compared. The results of a satisfaction questionnaire were also reviewed.

Results

Twelve months after surgery, BCVA was not significantly different in UT-DSAEK and DMEK eyes (0.10 ± 0.04 and 0.07 ± 0.07 logMAR, respectively); at both 4- and 6 mm optical zones total and posterior corneal higher order aberrations (HOAs), posterior astigmatism and total coma were significantly lower after DMEK; BCVA in both groups was significantly correlated mainly with anterior corneal aberrations; contrast sensitivity was higher after DMEK especially in mesopic conditions and at medium spatial frequencies; the endothelial cell density was similar, although slightly higher in the UT-DSAEK group (p = 0.10). The satisfaction questionnaire showed that although patients were highly satisfied from both procedures, more than half of them preferred DMEK and reported a more comfortable and quicker postoperative recovery.

Conclusions

DMEK and UT-DSAEK showed no evidence of difference in terms of postoperative BCVA, although DMEK had a better performance in terms of contrast sensitivity, posterior corneal aberrations and overall patient satisfaction.

Novel mutations in MFRP and PRSS56 are associated with posterior microphthalmos

Background: Biallelic pathogenic variants in MFRP and PRSS56 genes can be responsible for nanophthalmos (NO) or posterior microphthalmos (PM). This study describes detailed clinical and molecular findings in a series of five patients affected by PM from four unrelated families.Materials and Methods: All patients underwent a complete ophthalmological and genetic evaluation. For proper and deep phenotyping a multimodal instrumental approach was used for all cases: B-scan ultrasound, spectral domain optical coherence tomography (SD-OCT), fundus retinal imaging and anterior segment data were obtained. Molecular analysis of PRSS56 and MFRP genes was performed with Next-Generation Sequencing (NGS) methodology and segregation analysis on parents and one affected sibling was performed with Sanger sequencing.Results: A very high hyperopia of +14.00D or more was the main refractive error and macular abnormalities were identified in all patients. Axial length ranged from 15.3 mm to 17.86 mm (mean 16.58 mm) and age at first presentation ranged from 6 to 36 months (mean 18 months). Anterior chamber depth was within normal values, according to age, while total axial length was severely reduced in all patients. All our patients met the diagnostic criteria for PM. Three patients, including a pair of siblings, carried compound heterozygous mutations in the PRSS56 gene; in the other two patients, one homozygous or two compound heterozygous mutations in the MFRP gene were detected.Conclusion: Our study describes four novel mutations in the PRSS56 gene and one in the MFRP gene in patients with non-syndromic posterior microphthalmos. Proper genotype-phenotype correlation and early diagnosis could lead to good functional results.

Response to sexual assault: a relational perspective

It has been suggested that although the severity of the stressor is the primary determinant of acute posttraumatic stress disorder (PTSD) symptoms, pre-existing personality patterns may be the primary contributors to the development of chronic PTSD symptomatology. The authors postulate that of the multiple personality factors that influence behavior and response to traumatic events, relational capacity or the ability to sustain interpersonal relationships provides an overarching construct for understanding the contribution of social contextual factors to post-trauma response. The results of this exploratory study support the authors' hypothesis that relational capacity is a significant factor in explaining persistent PTSD symptoms in a sample of adult women who have been raped. Significant correlations were found between measures of relational capacity, the Bell Object Relations Inventory and the Inventory of Interpersonal Problems and measures of distress, the Posttraumatic Symptom Scale, and the Beck Depression Inventory.

The Objective Behavioral Index: a measure for assessing treatment response of patients with severe personality disorders

A measure that captures the frequency and intensity of experienced dysfunctional behaviors as well as the use of mental health services was developed and tested as part of a treatment controlled trial of patients with borderline personality disorder. The Objective Behavioral Index (OBI) was completed by 136 subjects with the diagnosis of borderline personality disorder before random assignment to treatment and by 35 subjects at each follow-up point. With one exception, the OBI subindexes (Dysfunctional Behaviors and Service Utilization) were not intercorrelated nor were they associated with any of the other patient status measures. Both of the OBI subindexes were sensitive to change after a course of psychotherapy. The OBI measurement system is easy to use and provides important information about behavioral dysfunction and service utilization. Also, contrary to expectations, service utilization is not associated with patient symptomatic and behavioral status.

The contribution of group cohesion and group alliance to the outcome of group psychotherapy

The contribution to outcome of two group-process factors, group cohesion and group therapeutic alliance, was tested in the context of a randomized, controlled treatment trial for borderline personality disorder. Group members from four time-limited groups of an experimental model of group psychotherapy completed measures of group cohesion and group alliance at prespecified intervals across the 30-session therapy. Outcome was measured in terms of psychiatric symptoms, social adaptation, and indicators of behavioral dysfunction. The results showed that cohesion and alliance were correlated significantly and separately contributed to outcome on most of the dependent measures. Stepwise regression analyses showed, however, that when compared with cohesion, alliance accounted for more outcome variance on the dependent measures. The clinical implications of the findings and the limitations of the study are discussed.

Emotion processing in borderline personality disorders

The aim of this study was to examine the ways in which adults with borderline personality disorder (BPD) experience and manage their feelings. Responses of 30 subjects who met the criteria for BPD on the Structured Clinical Interview for DSM-III-R were compared with 40 non-BPD controls on the following measures of emotion processing and affect regulation: 1) level of emotional awareness, 2) capacity to coordinate mixed valence feelings, 3) accuracy at identifying facial expressions of emotion, and 4) intensity of response to negative emotions. The results showed significant differences between the two groups on all measures. The borderlines showed significantly lower levels of emotional awareness, less capacity to coordinate mixed valence feelings, lower accuracy at recognizing facial expressions of emotion, and more intense responses to negative emotions than the nonborderline controls. The findings corroborate clinical observations of borderline patients' difficulties in regulating emotions. The implications of the results for the therapeutic management of BPD patients are discussed.

Severity as a diagnostic dimension of borderline personality disorder

The purpose of this study was to identify diagnostic and severity subgroups within a cohort of patients with borderline personality disorder (BPD). Of 171 patients clinically diagnosed with BPD, 132 were Diagnostic Interview for Borderlines (DIB) positive. Through a process of random selection, 41 of the DIB positive subjects were also interviewed with the revised version of the DIB (DIBR) and approximately one half with two semi-structured research interviews, the Schedule for Affective Disorders (SADS) and the Personality Disorder Examination (PDE). All subjects completed four self-report measures of problematic behaviours, symptoms and social adaptation. The analyses included examination of: 1. the correspondence of the BPD diagnosis across the DIB, the DIBR and the PDE; 2. the association between DIBR scoring levels and scores on measures of symptoms and behavioural status; and 3. the co-occurrence of BPD with Axis I and other Axis II disorders. Correlations and analyses of variance between both the DIB and DIBR scoring levels and the scores on the four symptom and behavioural measures showed that the scoring levels (DIB 7 to 10; DIBR 8 to 10) could be used to distinguish three subgroups of BPD. The three groups differed in terms of concordance for BPD with the PDE and in terms of patterns of overlap with DSM-III-R, Axis I and other Axis II disorders. This study shows that BPD subgroups can be located on a continuum of symptomatic and behavioural severity and that each subgroup has a specific pattern of overlap with Axis I and other Axis II disorders.

The assessment of ego development in borderline personality disorders

The purpose of the study was to assess levels of ego functioning in a cohort of patients who met the criteria for borderline personality disorder. The Sentence Completion Test (SCT) and the Descriptions of Significant Others (DSO) test were used to measure dimensions of ego maturity. The borderline patients' responses on the SCT were compared with the responses of an outpatient sample of psychiatric patients and with general population norms established for the test. The scores on the SCT for a selected subgroup of five subjects were compared with their scores on the DSO. Contrary to expectation, the responses on the SCT by those with borderline personality disorder did not differ from those for the psychiatric outpatient sample or the general population norms. However the within-group comparisons between the SCT and the DSO for the subgroup of five subjects showed comparable trends between tests. Discussion of the results focuses on the interpretations of the borderline patients' responses to the two tests. Emphasis is placed on the need to distinguish subsets of ego functions, which can be assessed separately using a variety of measurement strategies.

Group and family treatments for borderline personality disorder

The authors review clinical and empirical studies on the effectiveness of group treatments and family-marital treatments for borderline patients. These studies support the use of the group format in treating borderline patients, but no empirical study has examined whether group treatment combined or sequenced with individual treatment, or individual treatment alone, is better than group treatment alone. Empirical studies of family interventions with borderline patients are lacking, but further research is warranted, since many studies have shown that family pathology, especially physical and sexual abuse, is related to the development of borderline pathology.

A comparison of three measures for the diagnosis of borderline personality disorder

Three instruments for diagnosing borderline personality disorder were administered to 22 outpatients. There was poor concordance among the indexes for the identification of the disorder, and more than half of the sample received more than two DSM-III axis II diagnoses.

Time-limited, group psychotherapy for borderline patients

Preparation for treatment, group process and time boundaries are presented as components of a treatment model designed to respond to specific problems inherent in the nature of borderline personality disorder. A pilot study of the proposed treatment model is underway and one case illustration from this study is described to illustrate the adaptation to this treatment of a borderline patient with an extensive prior history of individual treatment.

Three viewpoints on the therapeutic alliance. Similarities, differences, and associations with psychotherapy outcome

This study tested three systems for measuring patient and therapist contributions to the therapeutic relationship. Scales with parallel dimensions were used by patients, therapists, and clinician judges to rate the same therapy hours. The sample consisted of 42 patients selected on specific criteria for their suitability for brief psychotherapy (20 sessions). They were treated by experienced psychodynamic therapists and therapeutic change was assessed by six outcome measures. Similarities and differences between the three perspectives of the alliance and their association with outcome were examined. There were significant correlations between patients', therapists', and nonparticipant judges' ratings of the patients' positive and negative contributions and the therapists' positive contributions, but no agreement between the three perspectives in their estimates of therapists' negative contributions. Within each measurement system, patients' and therapists' positive contributions to the relationship were the best predictors of outcome. In conclusion, the results suggest that the patients' and therapists' ratings of the treatment relationship, although influenced by subjective bias, agree to some extent with the nonparticipant judges' ratings and are more powerful in predicting the outcome of psychotherapy.

Analysis of emotional status during the hospital treatment of a borderline patient

This single case study illustrates a methodology for identifying recurrent pathological emotional states in a hospitalized, borderline patient. Parallel therapeutic inputs are delineated and examined in terms of patient-specific responses. The results indicate that ratings of nursing notes recorded across three periods of hospitalization can reliably isolate the patient's most salient and debilitating emotional states. State-specific therapeutic interventions are extracted and their effectiveness noted. The analyses illustrate clinical phenomena which are congruent with what is known about borderline symptomatology. In addition, the study locates therapeutic errors which often occur when working with difficult patients.

Psychotherapy practice and research: the interface

The study of the psychotherapeutic process presents special problems to clinicians and clinician investigators. In the absence of supportive, working relationships between the therapist, patient and investigator, important data about therapeutic transactions cannot be obtained. In addition, we are lacking methodologies for isolating the significant therapeutic factors which explain variations in the outcome of psychotherapy. These problems need to be jointly addressed by clinicians and investigators if we are to advance the theory and practice of psychotherapy.

Therapeutic alliance scales: development and relationship to psychotherapy outcome

The authors describe the development of patient and therapist alliance scales and their application to the therapies of selected patients with good and poor outcomes following brief psychodynamic psychotherapy. They focus on therapist and patient contributions to the attitudinal-affective climate of the therapy rather than on specific therapist techniques. The findings support the value of separating the contributions to the therapeutic alliance made individually by the therapist and the patient. Only the patient's contribution to the therapeutic alliance was predictive of outcome. Patients who developed and maintained positive attitudes toward the therapist and the work of therapy achieved the greatest gains.
