Subconjunctival bevacizumab in the impending recurrent pterygia

The aim of this study is to evaluate the efficacy and safety of subconjunctival bevacizumab injection(s) in the treatment of impending recurrent pterygia. Twenty-three eyes of 23 patients who developed impending recurrence after pterygium surgery with conjunctival autografting and were treated with subconjunctival bevacizumab injection(s) (2.5 mg/0.1 mL) were included in the study. Anterior segment photographs were taken prior to and at 1 week, 1, 3 and 6 months after the injection, and at the end of the follow-up period. Image analysis was performed using an image processing and analysis software program. Recurrence rate and complications were recorded. The mean age and follow-up time of the patients were 51.2 ± 6.2 (31–60 years) and 16.8 ± 3.1 (12–22 months), respectively. The average number of injections was 2 ± 0.78 (1–3). Sixteen eyes required re-injection (two injections in nine eyes, three injections in seven eyes), due to progression of vascularization. There were significant differences between size percentage of lesions before injection and at 1 week, 1, 3 and 6 months after the injection (p < 0.05 for all). Corneal recurrence developed in only one patient and no ocular or systemic side-effects of bevacizumab were observed. Repeated injections of bevacizumab may help to prevent the high recurrence rate of residual impending pterygium, due to its adjuvant role in decreasing lesion size, especially in the first year after surgery.     

Prostaglandin transporter mutations cause pachydermoperiostosis with myelofibrosis

Pachydermoperiostosis, or primary hypertrophic osteoarthropathy (PHO), is an inherited multisystem disorder, whose features closely mimic the reactive osteoarthropathy that commonly accompanies neoplastic and inflammatory pathologies. We previously described deficiency of the prostaglandin-degrading enzyme 15-hydroxyprostaglandin dehydrogenase (HPGD) as a cause of this condition, implicating elevated circulating prostaglandin E(2) (PGE(2)) as causative of PHO, and perhaps also as the principal mediator of secondary HO. However, PHO is genetically heterogeneous. Here, we use whole-exome sequencing to identify recessive mutations of the prostaglandin transporter SLCO2A1, in individuals lacking HPGD mutations. We performed exome sequencing of four probands with severe PHO, followed by conventional mutation analysis of SLCO2A1 in nine others. Biallelic SLCO2A1 mutations were identified in 12 of the 13 families. Affected individuals had elevated urinary PGE(2), but unlike HPGD-deficient patients, also excreted considerable quantities of the PGE(2) metabolite, PGE-M. Clinical differences between the two groups were also identified, notably that SLCO2A1-deficient individuals have a high frequency of severe anemia due to myelofibrosis. These findings reinforce the key role of systemic or local prostaglandin excess as the stimulus to HO. They also suggest that the induction or maintenance of hematopoietic stem cells by prostaglandin may depend upon transporter activity.     

An art therapy intervention for symptoms of post-traumatic stress,depression and anxiety among Syrian refugee children

This study first examined the prevalence of psychological symptoms among Syrian refugee children (N = 64) and assessed the effect of an art therapy intervention on post-traumatic stress, depression and anxiety symptoms. The Stressful Life Events (SLE) Questionnaire was used to measure stressful and traumatic experiences. The main outcome measures were UCLA Post-Traumatic Stress Disorder Parent version, Child Depression Inventory and State-Trait Anxiety Scale. After the baseline assessment, a five-day art therapy intervention, which is based on Skills for Psychological Recovery, was implemented. Findings of the study indicated that 60.3% (N = 35) of Syrian children who participated had high risk to develop post-traumatic stress disorder (PTSD) according to the SLE scale. The 23.4% of the children had PTSD symptoms while the 17.6% showed severe depression symptoms. Moreover, the 14.4% of the children showed severe levels of state anxiety symptoms and the 31.1% showed severe levels of trait anxiety symptoms. Findings of the study indicated that trauma, depression and trait anxiety symptoms of children were significantly reduced at the post-assessment. However, for state anxiety scores, significant differences between pre- and post-assessments did not appear. Therefore, it could be said that art therapy may be an effective method to reduce post-traumatic stress disorder, depression and trait anxiety symptoms among refugee children.     

Sexual dysfunctions in patients with neurodermatitis and psoriasis

We investigated sexual dysfunction and accompanying depression in patients with neurodermatitis and psoriasis. Patients with neurodermatitis (n = 31) and psoriasis (n = 24) were compared to control cases (n = 33) with Beck depression scale (BDS) and Arizona Sexual Experience Scale (ASEX). Beck Depression Scale and ASEX scores varied between three groups. In two group comparisons, the neurodermatitis group had more sexual problems than the psoriasis group and the control group. Patients with neurodermatitis and psoriasis have sexual dysfunction and depression in the course of these chronic diseases and the higher frequency of sexual problems was seen in patients with neurodermatitis.
