Background: Flexible flatfoot (FF) is a common foot deformity that can often consist of foot pain. Surgical treatment is designed to lengthen the lateral column.

Objectives: To resolve whether radiographic standing feet measurements of normo-plantigrade feet and FF, symptomatic or not, differ and to determine whether the lateral column is shorter.

Methods: The study comprised 72 patients (127 feet) consecutive patients, 18 years of age and older, who were divided into three groups: normal feet (56), asymptomatic FF (29), and symptomatic FF (42). All patients had a standing anterior posterior (AP) and lateral radiographs. AP images were used for the measurement of the talocalcaneal angle, talar-1st metatarsal angle, and talonavicular coverage. Lateral X-rays were used to estimate the talocalcaneal angle, talar-1st metatarsal angle, calcaneal pitch, naviculocuboid overlap, and column ratio.

Results: All three of the AP radiograph measurements differed among groups, and higher values were measured in the symptomatic FF group. Post hoc analysis found that the talonavicular coverage and the talocalcaneal angles also differed between symptomatic and asymptomatic FF patients. While some lateral measurements differed within groups, only the lateral talar-1st metatarsal angle distinguished between asymptomatic and symptomatic patients. The lateral column length was not found to be shorter among FF patients, weather symptomatic or not.

Conclusions: Only the talonavicular coverage, the AP talocalcaneal, and the lateral talar-1st metatarsal angles were found to differ between asymptomatic and symptomatic FF patients. The lateral column was not found to be shorter

Background: In an effort to alter eye color during World War II, devout Nazi researcher Karin Magnussen had adrenaline eye drops administered to inmates at the concentration camp Auschwitz-Birkenau. A Sinti family, with a high prevalence of heterochromia iridis, was forced to participate in this study. Members of this family, as well as other victims, were later killed and had their eyes enucleated and sent to Magnussen for examination. Magnussen articulated the findings of these events in a manuscript that has never been published. The author is the first ophthalmologist to review this manuscript. The generation who experienced the atrocities of World War II will soon be gone and awareness of what happened during this tragic chapter of world history is fading.

Objectives: To describe these events to raise awareness among future generations.

Methods: A literature review and archival search was conducted.

Results: Magnussen’s research was based on an animal study published in 1937. For Magnussen’s study, adrenaline drops were administered to inmates, including a 12-year-old girl from the Sinti family. As there was a reported case of deaf-mutism within the family, Waardenburg syndrome seems to be the most plausible explanation for this family’s heritable heterochromia.

Conclusions: The effort to change eye color was doomed to fail from the beginning because there was a probable diagnosis of Waardenburg syndrome. Extinction of humans for ophthalmological research is an insane act beyond imagination. For the sake of these victims, and for the generations who still feel their pain, it is imperative to tell their stories.

Background: The use of a high flow nasal cannula (HFNC) was examined for different clinical indications in the critically ill.

Objectives: To describe a single center experience with HFNC in post-extubation critical care patients by using clinical indices.

Methods: In this single center study, the authors retrospectively evaluated the outcome of patients who were connected to the HFNC after their extubation in the intensive care unit (ICU). At 48 hours after the extubation, the patients were divided into three groups: the group weaned from HFNC, the ongoing HFNC group, and the already intubated group.

Results: Of the 80 patients who were included, 42 patients were without HFNC support at 48 hours after extubation, 22 and 16 patients were with ongoing HFNC support and already intubated by this time frame, respectively. The mean ROX index (the ratio of SpO2 divided by fraction of inspired oxygen to respiratory rate) at 6 hours of the weaned group was 12.3 versus 9.3 in the ongoing HFNC group, and 8.5 in the reintubated group (P = 0.02). The groups were significantly different by the ICU length of stay, tracheostomy rate, and mortality.

Conclusions: Among patients treated with HFNC post-extubation of those who had a higher ROX index were less likely to undergo reintubation.

Background: Warm compresses are widely touted as an effective treatment for ocular surface disorders. Black tea compresses are a common household remedy, although there is no evidence in the medical literature proving their effect and their use may lead to harmful side effects. 

Objectives: To describe a case in which the application of black tea to an eye with a corneal epithelial defect led to anterior stromal discoloration; evaluate the prevalence of hot tea compress use; and analyze, in vitro, the discoloring effect of tea compresses on a model of a porcine eye.

Methods: We assessed the prevalence of hot tea compresses in our community and explored the effect of warm tea compresses on the cornea when the corneal epithelium’s integrity is disrupted. An in vitro experiment in which warm compresses were applied to 18 fresh porcine eyes was performed. In half the eyes a corneal epithelial defect was created and in the other half the epithelium was intact. Both groups were divided into subgroups of three eyes each and treated experimentally with warm black tea compresses, pure water, or chamomile tea compresses. We also performed a study in patients with a history of tea compress use. 

Results: Brown discoloration of the anterior stroma appeared only in the porcine corneas that had an epithelial defect and were treated with black tea compresses. No other eyes from any group showed discoloration. Of the patients included in our survey, approximately 50% had applied some sort of tea ingredient as a solid compressor or as the hot liquid.

Conclusions: An intact corneal epithelium serves as an effective barrier against tea-stain discoloration. Only when this layer is disrupted does the damage occur. Therefore, direct application of black tea (Camellia sinensis) to a cornea with an epithelial defect should be avoided.

Background: Cannabis has been used throughout history for different purposes but was outlawed in the United States in 1937 followed by most countries. Although recently reintroduced as a medical treatment in several countries, the use of cannabis in Israel is permitted for some medical purposes but is still controversial, eliciting heated public and professional debate. The few published studies on physicians' attitudes to medical cannabis found them to be generally unsupportive. 

Objectives: To examine, for the first time, the experience, knowledge and attitudes of Israeli physicians towards medical cannabis (MC). 

Methods: A 32 item questionnaire reflected physicians' demographics, knowledge of and experience with MC and their attitudes to this treatment. 

Results: Seventy-two physicians participated in this study. Physicians generally agreed that MC treatment could be helpful for chronic and for terminally ill patients (n=61, 79.2%). Oncologists and pain specialists did not agree unanimously that MC can undermine mental health, whereas other physicians did (P < 0.001, df = 4). Physicians who recommended MC in the past (once or more) agreed more than physicians who did not with the statement "MC treatment in Israel is accessible to patients who need it" (P < 0.05, df = 2). 

Conclusions: In contrast to other studies we found partial acceptance of MC as a therapeutic agent. Further in-depth studies are needed to address regulatory and educational needs.

 Background: Breast milk is well established as the ideal source of nutrition for infants. Mature human breast milk generally contains 3.5–4.5% lipids comprising mostly triacylglycerols. In general, the fat composition of maternal human milk in developing countries shows higher levels of saturated fats, reflecting diets rich in carbohydrates.

Objectives: To determine the profile of unsaturated fatty acids in the breast milk of two populations in southern Israel, Jewish and rural tent-dwelling Bedouin women.

Methods: This study involved 48 lactating Israeli mothers, 29 Jewish and 19 Bedouin (16–20 weeks postpartum), whose full-term infants were fed exclusively with breast milk. Total milk lipid extracts were transmethylated and analyzed by using an improved gas chromatographic method.

Results: The breast milk of the Bedouin women contained significantly higher levels of total major saturated fatty acids, lauric acid and palmitic acid (45.2 ± 4.7% vs. 41.0 ± 5.6%, P = 0.005; 5.2 ± 2.1 vs. 6.8 ± 2.0%, P = 0.03; and 22.7 ± 2.4 vs. 20.6 ± 3.8%, P = 0.02) respectively. No difference was found in the myristic acid level between the groups. The level of stearic acid was significantly higher in the Jewish group compared to the Bedouin group (5.7 ± 1.1 vs. 5.1 ± 1.1%, P = 0.04). There was a linear correlation between the levels of C14:0 and C12:0 in the Bedouin and Jewish groups respectively (R = 0.87, R = 0.82, P < 0.001).

Conclusions: Higher levels of saturated fatty acids were measured in the breast milk of Bedouin women, an economically weaker population. The results emphasize the importance of diet among lactating women and its influence on milk quality.

Background: Comorbid depression may play an important role in non-compliance with medical treatment among patients with chronic illnesses. Glaucoma is a potentially blinding chronic disease requiring life-long commitment to medical therapy. Patient's failure to adhere to anti-glaucoma treatment may lead to disease progression and visual loss.

Objectives: To assess the prevalence of depressive symptoms in glaucoma patients and the association between these symptoms and non-compliance with anti-glaucoma therapy.

Methods: This was a cross-sectional observational study. Compliance with pharmacotherapy was assessed with the Morisky Medication Adherence questionnaire (eight items). Screening for depression was performed by means of the CES-D scale (Center for Epidemiologic Studies Depression scale). The association between depression and compliance rates was analyzed.

Results: The study group comprised 76 glaucoma patients; 19.7% of the subjects were classified as "non-compliant" (Morisky cutoff < 10) and 21.1% suffered from depression (CES-D cutoff ≥ 16). We found a similar level of non-compliance when comparing depressed with non-depressed glaucoma patients. However, a significant correlation was observed between the level of depression and the level of non-compliance (P = 0.04).

Conclusions: Our study revealed a similar rate of depression in glaucoma patients and the general Israeli population. The presence of depression was not associated with the presence of non-compliance, yet the level of depression was associated with the level of non-compliance.

Background: Percutaneous angioplasty (PTA) and stenting is an established procedure for the treatment of hypertension caused by atherosclerotic renal artery stenosis. However recently, the decision whether or not to perform this procedure has raised considerable debate.

Objectives: To examine the association between the basic clinical and radiological characteristics of candidates for renal artery PTA and the clinical outcome of the procedure in terms of improvement of blood pressure control and renal function.

Methods: We conducted a retrospective cohort study of all patients who underwent percutaneous transluminal renal artery angioplasty (PTRA) and stent implantation in a tertiary medical center during the period 2000–2007. The clinical and radiological data were extracted from the medical file of each patient. Blood pressure measurements and creatinine level were recorded before the procedure and 1 month, 6 months, 12 months and 18 months after PTRA.

Results: Thirty-two patients were included in the final statistical analysis. The mean age of the study population was 66.6 ± 8.8 years old and 75% were men. There was a significant reduction in both systolic and diastolic blood pressure 1 month after the procedure: 160.5 ± 24.7 vs. 141.8 ± 23.6 mmHg and 83.8 ± 12.9 vs. 68.8 ± 11.8 mmHg respectively (P < 0.001). The reduction in blood pressure was constant throughout the follow-up period and was evident 18 months after the procedure: 160.5 ± 24.7 vs. 135.0 ± 35.1 mmHg and 83.8 ± 12.9 vs. 71.3 ± 16.5 mmHg respectively (P < 0.001). However, no improvement in renal function was observed at any time during the follow-up period. We could not demonstrate an association between clinical or radiological features and the clinical outcome after PTRA.

Conclusions: Our findings show that PTRA[1] can be considered an effective procedure for improving blood pressure control in patients with atherosclerotic renal artery stenosis (ARAS) and resistant hypertension. This research, together with previous studies, strengthens the knowledge that the decline in glomerular filtration rate seen in many patients with ARAS is non-reversible and is not improved by PTRA.
