Background: In recent decades cataract surgery has shifted slowly from public hospitals to ambulatory surgery centers, demonstrating changes in the profile of patients presenting to public hospitals for cataract surgery. These changes may potentially affect the complexity of surgeries, their volume, resident training, and perhaps also visual outcomes and patient satisfaction. 

Objectives: To assess the changes in the medical and demographic characteristics of patients undergoing cataract surgery in a public hospital over a period of 15 years. 

Methods: We retrospectively reviewed the records of patients undergoing preoperative assessment before cataract surgery. Records for the period October 2000 to January 2001 (100 patients), October 2006 to January 2007 (100 patients), and October 2013 to January 2014 (150 patients) were assessed for demographic, systemic and ocular related parameters. 

Results: There was a significant increase in the average age of patients (70.4, 72.4, 73.9 years, P = 0.026), with a significant increase in the percentage of patients of Arab ethnicity (17%, 11%, 28.7%, P = 0.002), and concomitant systemic co-morbidities (38%, 46%, 64.7%, P < 0.0001). There was an increase in the percentage of patients with narrow palpebral fissures (0%, 2%, 8%, P = 0.003), deep-set eyes (2%, 4%, 18%, P < 0.0001), dense nuclear sclerotic cataract (38%, 34.4%, 56.9%, P = 0.001), and a significant increase in the percentage of patients taking alpha-blocking medications (0%, 8%, 10.7 %, P = 0.004).

Conclusions: Patients presenting for cataract surgery in 2013 compared to those in earlier periods are older, sicker and have more ocular conditions potentially affecting cataract surgery outcomes, patient satisfaction and residents' training. 

 

Background: One of the most alarming ocular injury trends in recent years has been the proliferation of paintball guns and the proportional increase in the number of ocular eye injuries caused by paintballs.

Objectives: To describe five cases of paintball eye injuries that resulted in loss of functional vision in four of them.

Methods: We conducted a retrospective interventional case series of the clinical course of five patients with paintball eye injuries treated in the ophthalmology departments of two medical centers. 

Results: Five young males were evaluated for paintball injuries caused by blunt trauma. There was one case of full-thickness laceration (globe rupture). Four patients required one to five surgical interventions: three of these involved the removal of traumatic cataract including two eyes with significant zonular dehiscence treated by lens capsule conservation using anchoring devices, one retinal surgery and two glaucoma filtration surgeries. However, final visual outcome was not favorable due to irreversible retinal damage.

Conclusions: Paintball trauma often results in significant ocular injury and loss of functional vision despite successful surgical interventions. Most injuries are easily preventable and occur in under-supervised settings. Improved safety measures, strict regulation enforcement and appropriate public education could prevent such serious damage.

 

Background: It is common practice to use topical antiseptic formulations prior to specific therapy in superficial infections and injuries, but not in corneal bacterial ulcers. There is accumulating evidence proving chlorhexidine gluconate 0.02%, an antiseptic agent, as an effective treatment for infectious keratitis.

Objectives: To investigate the safety and efficacy of chlorhexidine gluconate 0.02% as an adjunct therapy for corneal bacterial ulcers.

Methods: Twenty-six patients with corneal bacterial ulcers were treated with standard empirical antibiotic treatment. The study group was treated with chlorhexidine gluconate 0.02% while controls received placebo for one week. The patients were followed for at least 1 month.

Results: No allergic or toxic reactions were noted. Although a higher baseline severity of ulcers existed in the study group, no differences were found in final vision, scarring extent, or recovery duration.

Conclusions: Chlorhexidine gluconate 0.02% may improve the clinical course of corneal ulcers.
 

Background: The Muslim Circassians in Israel represent a unique ethnic community, distinct from Jews and Arabs. This endogamous group has a limited genetic variability that allows studying risk factors associated with type 2 diabetes.

Objectives: To estimate the prevalence of type 2 diabetes among Israeli Circassians and its correlation to obesity and genetic susceptibility.

Methods: Israeli Circassian women (n=450) and men (n=289) older than 35 were included in the study. They were classified as having or not having diabetes, and their risk factors, including hypertension, body mass index, family history of diabetes, and laboratory tests, were examined retrospectively.

Results: The age-adjusted prevalence of diabetes among the 739 participants was 12% (men 14.6%, women 10.7%). It was higher among those with BMI[1] > 30 than in those with lower BMI and a family history of diabetes without high BMI. But the risk of diabetes with BMI > 30 plus a family history was three times higher than when these factors were missing (odds ratio 2.96, 95% confidence interval 1.30–6.6). Multivariate analysis, however, found familial history of diabetes to be the strongest risk factor, independent of obesity (OR[2] 2.47, 95% CI[3] 1.45–4.20).

Conclusions: The results yielded by this homogeneous Circassian population, sharing the same environmental influences and having an endogamous pattern of marriage, suggest a role of genetic risk factors for diabetes. Israeli Circassians are suitable for additional genetic studies that may lead to the identification of susceptibility genes for type 2 diabetes.

Background: Previous reports on the behavior of procalcitonin blood levels in diverse clinical conditions suggest that it is part of the activation of cellular immunity and is another acute-phase reactant.

Objective: To compare procalcitonin with C-reactive protein, a well-known acute-phase reactant, in a series of acutely febrile pediatric patients and to review recent literature on procalcitonin.

Methods: Procalcitonin and CRP levels were evaluated in 38 blood samples of pediatric patients who were admitted to the Dana Children’s Hospital for evaluation of unexplained fever or for sepsis work-up.

Results: The parallelism between procalcitonin and CRP was found to be highly significant (P<0.01).

Conclusion: The rise of procalcitonin blood levels in febrile pediatric patients suggests that it is part of the acute-phase reaction, parallel with the CRP reaction.
