Eyelid Hyperlaxity and Obstructive Sleep Apnea (O.S.A.) Syndrome
Authors: Robert P.Y. , Adenis J.P. , Tapie P. , Melloni B. 
Published: April 2018

Purpose. An association between the floppy eyelid syndrome and the obstructive sleep apnea syndrome (O.S.A.) has been reported. We studied eyelid tissue elasticity and other ophthalmologic findings in a large number of patients with sleep disorders. Material and Methods. Sixty-nine patients with sleep disorders were evaluated. Two thirds were found to have O.S.A., and one third was treated at night by nasal continuous positive airway pressure (nasal C.P.A.P.). Slit lamp examination, eyelid measurements and Schirmer test were performed. Results. Eyelid hyperlaxity was increased in patients with O.S.A. The floppy eyelid syndrome (associated papillary conjunctivitis), however, was rare. Associated corneal lesions were rare, and most patients were asymptomatic. In some cases, ocular irritation was due to air leaks from nasal C.P.A.P. A significant proportion of patients required treatment for primary open angle glaucoma. Conclusions. Our study of 69 patients found an association between O.S.A. and eyelid hyperlaxity.
Causes of Enucleation: A Clinicopathological Study
Authors: Günalp I. , Gündüz K. , Özkan M. 
Published: April 2018

Background. Enucleation is an approach used for unresponsive end-stage ocular disease often resulting in blind, painful or cosmetically unacceptable eyes. Methods. We reviewed the clinicopathological data on 3506 enucleations performed over a 50-year period, 1945-1995. Histopathological data were divided into eight groups according to the causes leading to enucleation: trauma, phthisis, corneal disease, inflammation, vitreoretinal disease, glaucoma, tumors and infections. Results. The study considered 3506 enucleated eyes of 3482 patients, 2467 (70.8%) males and 1011 (29.1%) females (4 sex unspecified). The z-test showed there were significantly more enucleations in males for phthisis (p<5.05), infections (p<0.01), trauma (p<0.01) and inflammation (p<0.01) and more enucleations for tumors in females (p<0.01). There were no differences between males and females with regard to enucleations for glaucoma, vitreoretinal and corneal diseases (p>0.05). The 0–9 years age group was most frequently affected, accounting for 29.7% of the cases. Patients aged less than 30 years constituted 53.6% of all enucleations. The primary or underlying causes leading to enucleation were tumors (1185 eyes, 33.8%), phthisis (587 eyes, 16.7), glaucoma (561 eyes, 16.0%), vitreoretinal diseases (320 eyes, 9.1%), infections (259 eyes, 7.4%), corneal disease (229 eyes, 6.5%), trauma (209 eyes, 6.0%) and inflammation (156 eyes, 4.4%). Time trends in enucleating eyes with different causes showed the number of enucleations for phthisis, infections, corneal diseases, trauma and inflammations had dropped during the ten-year period 1986–1995 compared to 1976–1985 (z-test, p<0.01). There were no real changes in enucleations for glaucoma and vitreoretinal diseases and there was an increase in the number of enucleations for tumors (p<0.01). Conclusions. Improved diagnostic and therapeutic methods, widespread use of photocoagulation in vascular disorders and vitreoretinal surgery in traumas, effective antimicrobial treatment, increasing use of corticosteroids and immunosuppressants, have contributed to the decreasing frequency of enucleation. Tumor patients generally presented late with advanced tumors totally filling the eye, not salvageable by other non-invasive treatment methods. Prompt diagnosis of intraocular malignant tumors (retinoblastoma and malignant melanoma) may reduce the need for enucleation.
Electrophysiological Assessment of Visual Pathways in Glaucoma
Authors: Parisi V. , Pernini C. , Guinetti C. , Neuschuler R. , Bucci M.G. 
Published: April 2018

Purpose. To assess nerve conduction in visual pathways in patients with open-angle glaucoma. Methods. Pattern-electroretinograms (PERG) and visual-evoked potentials (VEP) were simultaneously recorded in 16 patients with open-angle glaucoma (POAG) and 15 age-matched controls. The visual stimuli were checker-board patterns (the check edges subtend 15’; the contrast was 70% and reversed at the rate of 2 reversals/s). Results. POAG patients showed significantly higher PERG and VEP latencies (ANOVA: P<0.01) and significantly lower amplitudes than controls; the retinocortical time (RCT: difference between VEP P100 latency and PERG P50 latency) was longer (P<0.01) in POAG than controls and the longer RCT was correlated with the reduced PERG amplitude (r:0.798, P<0.01). Conclusions. This suggests that POAG patients have an involvement of the innermost retinal layers and impaired nerve conduction in their visual pathways.

Published: April 2018

The purpose of this study was to evaluate the hemodynamic changes occurring in the ophthalmic vasculature of eyes with Behçet's disease in a controlled clinical trial. Both eyes of patients with retinal involvement due to Behçet's disease were consecutively evaluated and were established as having mild or severe retinal vasculitis according to the ophthalmoscopic and fundus fluorescein angiographic findings. One eye from each patient was randomly selected and 25 eyes with mild to moderate and 25 eyes with severe vasculitis were identified. Color Doppler imaging (CDI) was used to quantitate blood flow velocities and vascular resistance in the ophthalmic artery (OA), central retinal artery (CRA) and central retinal vein (CRV) of these patients and those of 25 healthy volunteers. All three groups were age- and sex-matched. In the OA, peak systolic, end diastolic and average flow velocities were significantly higher in patients with Behçet's disease than in the control group (p<0.05). CRA blood flow velocities of patients with severe retinal involvement were significantly lower than those with mild to moderate vasculitis and control groups and the average vascular resistance was significantly higher than in the control group (p<0.05). Additionally, the average blood flow velocities in the CRV of patients with severe vasculitis were significantly lower than in mild to moderate vasculitis and control patients. Marked circulatory changes were seen in the ophthalmic vasculature of eyes with Behçet's disease. Although larger studies are required to define the true sensitivity and specificity of this technique, these initial results suggest that CDI could play a major part in the assessment of patients with ocular Behçet's disease.

Authors: Tejada P. , Méndez M.J. , Madero S. , Cava C. , Barcelo A. , Castellano V. 
Published: April 2018

Purpose. 1-Octadecene is a hydrocarbon with one double bond in its structure that could serve as a solvent for ferrofluids. The aim of this pilot study was to obtain preliminary information on intraocular tolerance to 1-octadecene. Methods. Vitreous compression with perfluoropropane gas was achieved in 20 eyes of albino rabbits. Four days after gas injection a fluid-gas exchange was undertaken. Sixteen eyes received 1-octadecene. Four eyes received balanced salt solution. Eyes were obtained at 3, 7, 14 and 30 days. The samples were fixed in 10% buffered formalin, processed in paraffin and sections were stained with hematoxylin and eosin. Results. Emulsification of the oil bubble was observed in 31.25% of the cases by the fifth day; light microscopy showed normal retinal architecture in all the eyes and epiretinal and vitreous macrophages in 50% of the eyes. Conclusions. 1-Octadecene does not appear to have any retinal cytotoxic effect but elicits an inflammatory response in the vitreous activity.

Authors: Koçak I. , Zulauf M. , Hendrickson P. , Stümpfig D. 
Published: April 2018

Background Brusini developed a new interpretation system for Octopus and Humphrey automated perimeters that is based on mean defect (MD) and corrected loss variance (CLV) or corrected pattern standard deviation (CPSD). This study tested the performance of Brusini's glaucoma staging system (GSS) in staging and follow-up. Methods Retrospectively, 610 visual fields of 64 eyes of open-angle glaucoma patients were analyzed with Brusini GSS and compared with Aulhorn-Karmeyer stages and by PeriData 7.0 trend analysis. Results Follow-up was comparable to PeriData 7.0 trend analysis in 97%. Change was observed in 41% of eyes, i.e., initial improvement (19% eyes), deterioration (16%), and after an initial improvement, either deterioration (11%) or a stable period (5%). No change was seen in 59% of the eyes, of which 30% showed small and 19% high long-term fluctuation (LF) due to fatigue effect, poor cooperation of patient, impaired reliability, or short-term fluctuation (SF) greater than 1.7 dB. However, for 8% of the eyes there was no apparent reason for high LF. Conclusions Brusini GSS is useful for staging and recommended for follow-up evaluation of visual fields in glaucoma.

Published: April 2018

Purpose To compare the efficacy and safety of a newly developed ophthalmic solution containing carteolol 2% and pilocarpine (2% (CBS341A) with a timolol 0.5% and pilocarpine 2% fixed combination. Patients and Methods. A randomized, double-masked, multicenter study was conducted in 209 patients with primary open-angle glaucoma or ocular hypertension, whose intraocular pressure (IOP) was higher than 21 mm Hg on bet-blocker twice a day alone. The test medications were administered twice daily for 4 months. IOP was measured at 9 and 11 a.m. at the beginning of the study (with beta-blocker alone) and after one and four months of treatment. Adverse effects were recorded. Results Both combinations caused a similar, statistically significant decrease in IOP. At four months, in the CBS341A group a 2.4 mm Hg (9%) reduction in IOP was achieved at 9 a.m. and 4.1 mm Hg (17.3%) at 11 a.m. compared with respectively 3 mm Hg (11%) and 4.5 mm Hg (19.5%) in the timolol-pilocarpine group. No statistical difference was observed between the two groups in safety and efficacy. Conclusions The carteolol-pilocarpine combination appears as safe and as effective as the timolol-pilocarpine combination in the medical treatment of primary open-angle glaucoma or ocular hypertension.

Authors: Tabandeh H. , Kon C. , Rostron C. , Luke I. 
Published: April 2018

Purpose A systemic disease may be diagnosed for the first time in patients who present to the eye department with ophthalmological manifestations. This study documents the pattern of systemic disorders which were encountered in an emergency eye clinic for the first time. Subjects and method. Over a period of six months details of all patients who had a previously unknown systemic condition diagnosed in the Emergency Eye Clinic were recorded. Patients were seen in this clinic upon referral from other practitioners. All patients, with the exception of those with minor ophthalmic problems, were screened for hypertension and glycosuria. The patients were subsequently referred to their general practitioner or the appropriate hospital specialist for further management. Results During this period 1025 new patients visited the emergency eye clinic. Previously undiagnosed systemic disease was present in 86 patients (8.4%). The commonest disorders were neurological 35 (41%), cardiovascular 17 (20%), glycosuria 13 (15%) and respiratory 5 (6%). Visual disturbance and pain were the most frequent ocular presentation. In 54 patients (62.8%) the ocular condition was a direct manifestation of the systemic condition and in 32 patients (37.2%) the systemic disease was a coincidental finding. Conclusions Awareness of ophthalmological manifestations of systemic disorders helps in the early diagnosis of these conditions and reduces the resulting morbidity and possibly mortality. This study illustrates the hidden role of the emergency eye clinic in identifying patients with an underlying systemic condition.
Eyelid Malpositions after Cataract Surgery
Authors: Hosal B.M. , Tekeli O. , Gürsel E. 
Published: April 2018

Purpose. To estimate the incidence and the factors that may play a role in the etiology of eyelid malpositions after cataract extraction. Methods. We followed up 124 patients for six months after cataract extraction. Palpebral aperture, levator function, height of the upper lid crease, lower eyelid laxity and position of the punctums were recorded preoperatively and postoperatively. Post-cataract ptosis was defined as a 2 mm or greater drop in the lid margin after correcting for any change in the fellow eye. Results. None of the patients developed ectropion or entropion, but five (4%) developed punctal ectropion after surgery. The incidence of post-cataract ptosis was 7.3% at six months. Age, sex, preoperative measurements of levator function, lid crease and dermatochalasis were not predictive for the development of ptosis at six months. However, there was a significant difference in the preoperative palpebral fissure width between the patients with ptosis and those without (p<0.05). There was a positive correlation between the mean volume of local anesthetic and the degree of ptosis on the first postoperative day (p<0.05, r: 0.1873). The presence and amount of ptosis on the first postoperative day was the best predictor of post-cataract ptosis at six months (p<0.001). Conclusions. Several factors are involved in the development of post-cataract ptosis. Temporary ptosis may be related to the myotoxicity of the local anesthetic. The presence of ptosis on the first postoperative day is the best predictor for the development of ptosis at six months.

Published: April 2018

Aim A multicentre, randomized, placebo-controlled double-masked study was conducted to assess the efficacy and safety of Rimexolone 1% eye drops in reducing inflammation after cataract surgery and intra-ocular lens implantation. Methods Rimexolone 1% (124 patients) or placebo (58 patients) was given, four times a day for 14 days starting 22-34 hours after surgery. All patients also received tobramycin 0.3% four times a day for 7 days. The clinical signs of ocular inflammation were recorded on days 1, 3, 8, 15 and 17 or 18. Results Rimexolone 1% markedly decreased the mean inflammation severity scores, and the sum of clinical assessments of cells and flare in the anterior chamber compared with placebo at each assessment. In addition, the percentage of patients with no anterior chamber inflammation was significantly higher with Rimexolone 1% than with the placebo at each assessment. All these results were statistically significant. Intra-ocular pressure did not rise after treatment with Rimexolone 1%. Conclusions The results suggest that Rimexolone 1% ophthalmic solution is an effective and safe steroidal anti-inflammatory agent for topical use following cataract surgery and intraocular lens implantation.
‘There is no sincerer love than the love of food’ (George Bernard Shaw, 1903): The meaning of food and its uses in prison subculture
Authors: Einat Tomer , Davidian Moran 
Published: April 2018

This study examines the ways in which the prison service handles food and analyses the uses and meanings of food in prison subculture. Using semi-structured interviews and content analysis, data were collected and analysed from 20 ex-prisoners who were incarcerated in maximum-security prison facilities for a period of three years or more. Our main findings are that, according to the interviewees’ testimonies, (a) the Israel Prison Service (IPS) makes manipulative and abusive use of food in order to perpetuate its power; and (b) food serves as a means to determine the relationship between prisoners and staff, govern social status or rejection in the prison subculture, or pass the time. We have four main conclusions. First, the IPS nutrition policy differentiates and discriminates among prisoners and clearly violates the basic human rights of prisoners, thus suggesting an abuse of power. Second, the IPS’s use of food as a tool for punishing or rewarding introduces and perpetuates inequalities and encourages the illegal prison trade in food and food products. Third, cooking in prison, especially in light of its illegality, constitutes a symbolic expression of resistance to the institution and a meaningful way of coping with boredom. Lastly, food and its possession in prison serve as very powerful tools for constructing and perpetuating exploitation and unequal power relations among prisoners. Although the study suffers from two limitations – the validity of the adolescents’ responses and the small sample size – its findings lead us to propose that an improvement in the food products that are accessible to prisoners and permission to cook in their cells are inexpensive and legitimate means of bettering both the prisoners’ quality of life and the social atmosphere in prison.

Published: April 2018

To better understand the health status of men in the United States, this study aimed to assess the association of hardship on the presence of and pain severity among men 50 years of age and older. Cross-sectional multivariate logistic regression analyses were conducted using the 2010 wave of the Health and Retirement Study ( N = 3,174) to assess the association between four hardship indicators and the presence of pain and pain severity among this sample of older men. Results suggest that the association between the presence of pain and hardship was statistically significant across all four indicators: ongoing financial hardship (CI [1.05, 1.63], p < .05), difficulty paying bills (CI [1.42, 3.02], p < .001), food insecurity (CI [1.46, 3.15], p < .001), and not taking medication due to cost (CI [1.06, 1.66], p < .05), even after adjusting for all demographic factors. The associations between pain severity and ongoing financial strain (CI [1.23, 2.83], p < .01) and difficulty paying bills (CI [1.02, 3.18], p < .05) were statistically significant. Results also indicate that education was a buffer at all levels. In addition, the interactive effect of hardship and Medicare insurance coverage on pain severity was significant only for ongoing financial strain (CI [1.74, 14.33], p > .001) and difficulty paying bills (CI [1.26, 7.05], p < .05). The evidence is clear that each hardship indicators is associated with the presence of pain and across some of the indicators in pain severity among men aged 50 and older. In addition, these findings stress the importance that Medicare insurance plays in acting as a buffer to alleviate some of the hardships experienced by older men. These findings also highlight the association between the presence of pain and pain severity for the overall quality of life, health outcomes, and financial position of men in later life.

Published: April 2018

Increasing evidence in the literature indicates that serum sialic acid is increased in cancer patients suggesting a possible usefulness of its determination as a tumor marker. However there are many discrepancies in the data reported, probably due to methodological errors, mainly in lipid bound sialic measurement. In this paper we illustrate the results obtained when we applied a method worked out in our laboratory for the determination of total and fractionated sialic acid (lipid and protein bound) to the analysis of sera from patients with ovarian tumors and the preliminary data on the follow up of selected cases. The potential pitfalls in using this relatively new tumor marker will be critically evaluated.
Terminal Deoxynucleotidyl Transferase, Tdt, as a Marker for Leukemia and Lymphoma Cells
Authors: Campagnari Francesco , Bombardieri Emilio , de Braud Filippo , Baldini Luca , Maiolo Anna Teresa 
Published: April 2018

Terminal deoxynucleotidyl transferase, TdT, was assayed in the mononucleate cells of blood and bone marrow from 121 patients with leukemias at the onset of disease and from 95 subjects with malignant lymphomas at diagnosis. This intracellular marker was also investigated by cytoimmunofluorescent tests in 17 other cases of initial leukemias and in 3 diagnosed lymphoblastic lymphomas. Generally, the TdT levels were significantly enhanced in the blasts of the following: acute undifferentiated leukemias; the more immature types of acute lymphoblastic leukemias i.e., the null, non-T non-B, common, early T and pre-B subgroups; a fraction of blastic crises in chronic myelogenous leukemias; and many lymphoblastic lymphomas. TdT might also be slightly increased in the mononucleate blood cells obtained from the most immature forms of acute myelogenous leukemias. Relapses with changes in cell phenotypes were occasionally observed in previously TdT-positive leukemias as a result of clonal evolution of the disease. The leukemias with blasts containing high levels of TdT were usually responsive to treatment with corticosteroids and vincristine. TdT is an oligoclonal marker characterizing several populations of undifferentiated or poorly differentiated blasts that tend to develop towards or along the lymphoid pathway. Together with specific immunological markers, this enzyme is useful to define the particular type of leukemic cells. It also serves to identify the quasi-lymphoblastic nature of the malignant clone, a helpful indication for the choice of therapy.
Serum Prostate-Specific Antigen Determination in Prostatic Carcinoma

Published: April 2018

Prostate-specific antigen (PSA) is a tissue-specific glycoprotein identified by Wang in 1979. It is synthesized in the prostate independently of prostatic acid phosphatase (PAP). A total of 199 subjects were divided into four groups: controls aged less than 50 years, controls aged more than 50 years, patients with benign prostatic hyperplasia (BPH) and patients with prostatic carcinoma. PSA cut-off value was set at 10 ng/ml (mean for the BPH group plus 2 SD). With this cut-off value PSA could not be used as an early predictor of prostatic carcinoma. The association of PSA and PAP in prostatic cancer increases the number of patients with positive biological markers.
Immunosuppressive Acidic Protein (Iap) and Ca 125 Assays in Detection of Human Ovarian Cancer: Preliminary Results
Authors: Castelli Mauro , Romano Patrizio , Atlante Giuseppe , Pozzi Maurizio , Ferrini Umberto 
Published: April 2018

Serum levels of the immunosuppressive acidic protein (IAP) and CA-125 were measured in 45 patients with ovarian tumors (30 malignant and 15 benign) before surgery. Concentrations of both markers were slightly increased in benign forms but still within the upper limit for controls. The sensitivity of IAP in detecting ovarian cancer was higher than CA-125 (83.4% versus 76.7%). Five false negatives were observed in IAP assay and seven for CA-125. Parallel determination of both markers, however, improved the diagnostic accuracy up to 90.0% of the total malignant cases. Combined measurements of circulating IAP and CA-125 are therefore recommended in the detection of ovarian cancers.
