Background: Acute, as opposed to chronic, anterior uveitis is rarely associated with macular or optic nerve  edema. Nevertheless, mild changes may not be visible on examination.

Objectives: To implement non-invasive ocular coherence tomography (OCT) for obtaining quantitative and qualitative data in the assessment of changes in macular morphology and peripapillary retinal nerve fiber layers in eyes with acute anterior uveitis.

Methods: This retrospective case-control study was conducted in patients with unilateral acute anterior uveitis lasting for up to one month. Patients with evidence of other ocular disease or who had undergone intraocular surgery were excluded. We reviewed the charts of 14 consecutive patients who were diagnosed with acute unilateral anterior uveitis between 2007 and 2008 at the Tel Aviv Medical Center. Data on demographic details, ophthalmic examination, macular thickness and peripapillary retinal nerve fiber layer (RNFL) thickness (as demonstrated by OCT) were retrieved. Retinal and RNFL thickness was compared between the healthy fellow eye (control) and the uveitic eye in the central and four perifoveal quadrant regions, and RNFL thickness was compared in the mean and four quadrant values by Student’s t-test.

Results: We evaluated 28 eyes of 7 males and 7 females (mean age 37.7 years, range 20–65). The diagnoses were: idiopathic in five patients, ankylosing spondylitis in five, Crohn’s disease in one patient and reactive arthritis in one. Nine patients were HLA-B27 positive. The retina and the peripapillary NFL in each area were thicker in the uveitic eyes compared to the controls. The difference was statistically significant. There was no correlation between the differences in OCT values and patients’ demographic characteristics.

Conclusions: OCT demonstrated that eyes with acute anterior uveitis had thicker maculae and thicker peripapillary RNFL than controls. This finding suggests that even milder anterior uveitis may be associated with some degree of posterior segment manifestations.

 Background: The major cause of visual impairment in diabetic patients is macular edema. The failure of laser photocoagulation in a large subgroup of patients with clinically significant diabetic macular edema has prompted interest in other treatment methods.

Objectives: To evaluate the long-term efficacy and safety of an intravitreal injection of triamcinolone acetonide for clinically significant diabetic macular edema.

Methods: In a retrospective case series 31 diabetic patients with persistent, recurrent or diffuse clinically significant diabetic macular edema received a single 4 mg (0.1 ml) intravitreal triamcinolone acetonide injection and were followed for at least 6 months. The main outcome measures evaluated were classified as primary: visual acuity and central macular thickness, and secondary: intraocular pressure and cataract progression. Statistical analyses included Student’s t-test, chi-square test and the McNamar test.

Results: Best visual acuity results were observed 2.6 ± 2.4 months post-injection. At that time the mean foveal thickness had decreased by 37% from a baseline of 455 ± 100 to 288 ± 99 µ (P < 0.001) and the mean visual acuity improved from 6/42 to 6/23 (P < 0.001). Final mean visual acuity after an average of 10 ± 1.8 months follow-up (range 6–13 months) was identical to the baseline, although mean foveal thickness was still significantly lower than the initial thickness (368 ± 166 vs. 455 ± 100 µ, P < 0.01). Statistical analysis did not identify any pre-injection prognostic factors for improved visual acuity. The only complications that occurred were elevated intraocular pressure in 42% of patients and cataract progression in 21%. There was no endophthalmitis.

Conclusions: Intravitreal injection of triamcinolone acetonide for clinically significant diabetic macular edema is effective in reducing foveal thickness and improving visual acuity in the short term. Longer follow-up revealed that visual acuity returned to pre-injection values, even though a modest decrease in the foveal thickness persisted. Further studies are needed to evaluate the long-term efficacy in conjunction with laser photocoagulation treatment.

Orbital dog bites, although uncommon, occur mostly in children and are reported to be associated with severe ocular adnexal injury without globe involvement.

Since the early 1980s demographic changes compelled Israel’s health system to dedicate efforts to establish modern geriatric services. This task was performed with the help of governmental and non-governmental institutions and was coordinated by the Division of Geriatrics and Long-Term Care Diseases of the Ministry of Health. Today, 20 years later, as a result of those efforts, geriatrics and geriatric services in Israel are thriving. Qualified staff, including physicians who specialized in geriatrics, are working to maintain a high quality of care in various geriatric settings. However, more resources should be allocated for research in order to maintain and to continue to develop geriatric medicine in Israel.

Objective: To reexamine the impact of prolonged nasogastric tube feeding on the oral microbiota and to explore the salivary flow and composition in elderly patients in long-term care.

Methods: We compared a group of elderly patients fed by nasogastric tube with a control group of elderly patients in long-term care who are fed orally. Bacteriologic studies were performed by culturing samples from the oropharynx. Saliva studies included quantitative and biochemical analysis of basal and stimulated salivary flow.

Results: Bacteriologic studies performed in 90 patients revealed a significantly higher prevalence of gram-negative bacteria in nasogastric tube-fed patients (73% vs. 13%, P < 0.001). It is emphasized that Pseudomonas aeruginosa and Klebsiella pneumoniae were commonly and exclusively isolated from the oral flora of the nasogastric tube-fed patients (P < 0.001, P < 0.05). In the saliva studies performed on 23 nasogastric tube-fed and 21 control patients, basal and stimulated salivary flow was not significantly different in the two groups, however the ratio of stimulated to basal flow was reduced in the nasogastric tube-fed group (P < 0.05). Significant differences were also found in the concentrations of sodium, amylase, phosphor and magnesium. Noteworthy was the concentration of uric acid, the main non-enzymatic antioxidant of saliva, which was significantly lower in nasogastric-tube fed patients (P < 0.002).

Conclusions: These findings suggest that prolonged nasogastric tube feeding is associated with pathologic colonization of the oropharynx and with alterations in the saliva that are related to the risk of aspiration pneumonia. Further research is called for, as well as a thorough revision of the existing oral cleansing procedures in these patients.

Background: While age at death is on the rise, the number of postmortem examinations is declining and is disproportionately low among the elderly population. Research on the subject of gender-associated pathology in the elderly is also scarce.

Objective: To seek eventual gender-related differences in autopsies of elderly patients.

Methods: We analyzed the data extracted from a published report on 93 PMEs[1] performed at a geriatric hospital during the past 20 years.

Results: Ninety-three autopsies, representing 1.2% of the 8,101 deaths during these 20 years, were performed. Forty-five of the deceased were women and 48 were men. The incidence of pulmonary embolism was significantly higher in women (28%) than in men (10%) (P< 0.02). There was no significant difference in the gender distribution of the other diagnoses.

Conclusion: Gender distribution of PME-based causes of death in elderly patients revealed a significant rate of pulmonary embolism in women. A thorough search of the medical literature revealed two previous studies with similar findings. Further research will determine whether pulmonary embolism is more frequent or whether it has a worse prognosis in frail elderly women.
