Objectives: To present two cases of subtrochanteric fractures related to bisphosphonate treatment and review of the current literature.

Conclusions: Despite the overall beneficial effect of bisphosphonates, further research is required to prevent this significant complication. 

Objectives: To assess the changes in ACPA titers in patients with RA after treatment with infliximab as a first biological agent, and to correlate these variations with non-infusion-related adverse effects.

Methods: In a prospective multicenter observational study involving 48 research centers, we assessed 139 patients with established moderate-to-severe RA diagnosed according to American College of Rheumatology criteria. Samples were collected before and 6–12 months after treatment.

Results: The mean age of the study patients was 50.6 years old, and 118 were female (84.9%). Statistically significant variations in ACPA titers were noted in 47 patients (before and after treatment) (P = 0.012). Overall, ACPA titers were decreased in 32 (65.3%) and increased in 15 (34.7%). No correlation was found between severe or mild adverse effects in patients presenting variations in ACPA titers.

Conclusions: The present study showed that infliximab affected ACPA titers, promoting mainly a decrease; however, this was not related to the occurrence of non-infusion-related adverse effects.

Objectives: To assess the results of endovascular revascularization for lower extremity ischemia in dialysis patients.

Methods: We conducted a retrospective review of all dialysis patients who underwent endovascular treatment for critical limb ischemia (CLI) in our institution between 2007 and 2011. Data collected included comorbidities, clinical presentation, anatomic distribution of vascular lesions, amputation and survival rates.

Results: We identified 50 limbs (41 patients). Indications included: gangrene in 22%, non-healing wounds in 45%, rest pain in 31%, and debilitating claudication in 4%. Mean follow-up was 12 months (1–51 months). Nineteen patients required amputations. Freedom from amputation at 5 years was 40%. Factors associated with amputation included non-healing wounds or gangrene (68% and 36% respectively) and diabetes (P < 0.05). The survival rate was 80% after 5 years.

Conclusions:  Despite improvement in endovascular techniques for lower extremity revascularization, the incidence of limb salvage among dialysis patients remains poor, resulting in a high rate of major amputations. 

Objectives: To evaluate the clinical course of four children with cricopharyngeal achalasia presenting to our clinic.

Methods: We conducted a 5 year retrospective chart review in a tertiary referral center.

Results: Four children were diagnosed with primary cricopharyngeal achalasia between 2006 and 2010. Diagnosis was established by videofluoroscopy and all underwent uneventful cricopharyngeal myotomy. Three children recovered completely and one child showed partial improvement. For residual UES spasm in a partially improved patient, botulinum toxin was injected into the UES which led to further improvement. Dysphagia recurred in one child who was successfully treated with botulinum toxin injection.

Conclusions: Cricopharyngeal myotomy is a safe procedure in infants and young children. Botulinum toxin injection of the UES was found to be effective in refractory cases. 

Objectives: To determine the effect of vitamin K on hip fracture patients treated with warfarin.

Methods: We retrospectively examined the management of 21 patients with hip fractures who were being treated with warfarin at the time of admission. Vitamin K was given to 11 of the 21 patients. A third group, which served as a control, consisting of 35 hip fracture patients who were not being treated with anticoagulants was also evaluated.

Results: Patients who received vitamin K took fewer days to reach target international normalized ratio (INR) (1.73 ± 0.90 vs. 4.30 ± 1.89, P < 0.001) and had less preoperative time (2.64 ± 1.12 vs. 5.10 ± 2.42 days, P < 0.008) when compared with patients who did not receive vitamin K. In addition, these patients had statistically significantly shorter hospitalization stays (9.4 ± 1.9 and 13.2 ± 4.9 days, one-sided P < 0.06). There was no difference in the amount of blood found in the wound drains (111.8 ± 68.5 vs. 103.0 ± 69.4 ml) or the number of blood units administered (1.45 ± 1.29 vs. 2.00 ± 2.75 units).

Conclusions: Treatment with vitamin K for hip fracture patients who receive warfarin shortens preoperative time, reduces the length of hospitalization and probably reduces morbidity and mortality.

 Background: Patients with transient ischemic attack (TIA) at a high risk of stroke can be identified and should be managed urgently.

Objectives: To investigate whether recognized recommendations are being implemented in Israel.

Methods: An Israeli nationwide registry on patients admitted with stroke and TIA was conducted in all acute care hospitals (NASIS registry) within 2 successive months during 2004, 2007 and 2010. A revised ABCD² score was applied retrospectively. Patients with TIA were divided into a low risk group (LRG, 0–3 points) and a high risk group (HRG, 4–6 points) and were compared to patients with minor ischemic strokes (MIS, NIHSS score ≤ 5 points).

Results: A total of 3336 patients were included (1023 with TIA: LRG 484, HRG 539, and MIS 2313). LRG patients were younger and had lower rates of most traditional risk factors as compared with HRG and MIS patients. Brain imaging was performed in almost all the patients. Ancillary tests (vascular and cardiac) were overall underused, yet were performed more in LRG (53.2% and 26.9% respectively) than in HRG patients (41.6%, 18.9%). Between periods there was no change in usage of ancillary tests for the LRG and a modest increase in both HRG and MIS patients. For performance of vascular investigations overall, the odds ratio was 1.69 (95% confidence interval 1.42–2.00) comparing 2010 with 2004, but 0.7 (95% CI 0.5–0.9) comparing HRG with LRG. Between periods an increase in statin usage was observed in all groups (OR 2.69, 95% CI 2.25–3.21) but was more marked in MIS patients (OR 3.06, 95% CI 2.47–3.8). 

Conclusions: The approach to TIA risk stratification and management in Israeli hospitals does not follow standards set by current guidelines. Standardized protocols for TIA should be used to assure effective management.
