Background: Arthritis and arthralgia are painful symptoms experienced by many elderly patients during hospitalization. Crystal-induced arthritis (CIA) is one of the most common causes of arthritis worldwide and represents the most common cause of acute arthritis in the elderly.  

Objective: To determine the incidence of both acute new onset or acute exacerbation of CIA among elderly patients hospitalized due to an acute medical illness.

Method: This study comprised 85 patients. Patients aged 70 years and older who complained of any articular pain were included in the study. Exclusion criteria were signs of septic arthritis, chronic use of steroids or non-steroidal anti-inflammatory drugs, or admission to the hospital due to an acute attack of CIA. 

Results: Synovial aspiration was performed in 76 patients (89%). Joint aspiration yielded a diagnosis in 67 of them (79%). The predominant type of crystal was calcium pyrophosphate dehydrate (68%) followed by monosodium urate (20%). The main causes of hospitalization were acute infectious disease (57%) followed by neurologic and cardiac diseases, 14% and 9% respectively, and orthopedic problems (6%). Among patients with acute infectious disease, the main causes were pulmonary (57%) and gastrointestinal (22%) infections. In 9 patients (12%) who underwent synovial aspiration, visible crystals were identified without a definite diagnosis.

Conclusion: Our study showed that hospitalization could be a risk factor for the development of CIA, and the time to diagnose CIA is during hospitalization for other acute illnesses.

 

Objectives: To evaluate the safety and applicability of the Elekta Synergy-S radiation unit for the treatment of spinal tumors.

Methods: We retrospectively reviewed all patients treated with stereotactic radiosurgery to spinal tumors between November 2007 and June 2011.

Results: Thirty-four patients were treated for 41 lesions. Treatment indications were local tumor control and pain palliation. The mean follow-up was 10.8 ± 11.6 months (range 0.5–38 months). No acute radiation toxicity or new neurological deficits occurred during the follow-up period. Local tumor control was achieved in 21 of the 24 lesions (87.5%) available for radiological follow-up at a median of 9.8 months (range 3–32 months). Good analgesia was achieved in 24/30 lesions (80%) that presented with intractable pain.

Conclusions: The safety and feasibility of delivering single and multiple-fraction stereotactic spinal irradiation was demonstrated and became a standard treatment option in our institution. 

Objectives: To evaluate in a randomized control trial whether uninterrupted administration of angiotensin II (AngII) blockade medications influence estimated glomerular filtration rate (eGFR) in patients undergoing non-emergent coronary angiography.

Methods: Patients receiving treatment with angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACE-I/ARB) were recruited consecutively. The enrolled subjects were randomized into three groups at a 1:1:1 ratio: group A (ACE/ARB stopped 24 hours prior to the procedure and restarted immediately after the procedure), group B (ACE/ARB stopped 24 hours prior to the procedure and restarted 24 hours after the procedure), and group C (ACE/ARB continued throughout the study period). Plasma creatinine was measured and eGFR was calculated according to the Cockroft-Gault equation before and 48 hours after the coronary angiography. The primary endpoint was a change in eGFR at 48 hours.

Results: Groups A, B and C comprised 30, 31 and 33 patients respectively. The mean age of the study population was 65 ± 12 years and 67% were males. Fifty percent of the subjects had diabetes mellitus. The primary endpoint analysis showed that at 48 hours after the procedure there was no difference in ΔeGFR between groups A and C (4.25 ± 12.19 vs. 4.65 ± 11.76, P = 0.90) and groups B and C (3.72 ± 17.42 vs. 4.65 ± 11.76, P = 0.82). In post-hoc analysis the patients were clustered according to the following groups: medical alternation (group A and B) versus control (group C) and to baseline eGFR ≥ 60 ml/min vs. eGFR < 60 ml/min. In patients with baseline eGFR < 60 ml/min the ΔeGFR (baseline eGFR-eGFR 48 hours post-angiography) was significantly different between the intervention vs. control group (median 5.61 vs. median -2.19, P = 0.03 respectively). While in patients with baseline eGFR ≥ 60 ml/min there was no significant difference in ΔeGFR between the intervention and control groups.

Conclusions: ACE-I and ARB can safely be used before and after coronary angiography in patients with eGFR ≥ 60 ml/min. 

Background: Multiple case series, mostly highly selected, have demonstrated a very high mortality following acute basilar artery occlusion. The more widespread availability and use of non-invasive vascular imaging over recent years has increased the rate of ABAO[1] diagnosis.

Objectives: To estimate the proportion of diagnosed ABAO among all-cause ischemic stroke in an era of increasing use of non-invasive vascular imaging and to compare the characteristics and outcomes between these two groups.

Methods: We compared 27 consecutive cases of ABAO identified in a university hospital between 2003 and 2007 to 311 unselected cases of ischemic stroke from two 4 month surveys.

Results: ABAO diagnosis increased from 0.3% of all-cause ischemic stroke (2003–2004) to 1.1% (2007), reflecting the increased use of non-invasive vascular imaging. In comparison to all-cause ischemic stroke, ABAO patients were younger (mean age 60 vs. 71 years), were more likely to be male (89% vs. 60%), had less atrial fibrillation (7% vs. 26%), more severe strokes (baseline NIHSS over 20: 52% vs. 12%), higher admission white cell count (12,000 vs. 9000 cells/mm³) lower admission systolic blood pressure (140 ± 24 vs. 153 ± 27 mmHg), higher in-hospital mortality rates (30% vs. 8%) and worse functional outcome (modified Rankin scale ≤ 3, 22% vs. 56%) (P < 0.05 for all). Rates of reperfusion therapy for ABAO increased from 0 in 2003–2004 to 60% in 2007.

Conclusions: In this study, ABAO patients represented approximately 1% of all-cause ischemic stroke and were about a decade younger than patients with all-cause ischemic stroke. We report a lower ABAO mortality compared to previous more selected case series; however, most survivors had a poor functional outcome. Given the marked clinical heterogeneity of ABAO, a low threshold for non-invasive vascular imaging with a view to definitive reperfusion treatment is needed.

Background: Salmonella species commonly produce acute gastroenteritis. The clinical course may be affected by factors such as age, immunosuppression, and underlying disorders.

Objectives: To investigate clinical and laboratory differences in the infected population and the risk of complications according to the different age groups.

Methods: The records of 295 patients with positive cultures for Salmonella were divided into six age groups and reviewed retrospectively for the years 1994–1997. Demographic, clinical and laboratory data, extraintestinal manifestations, underlying disorders, organism source, and susceptibilty to antibiotics were analyzed.

Results: We found that 88.5% were only stool positive, 9.2% had positive blood cultures, and 2.4% were positive in both blood and stool; 3.6% were found to have underlying disorders. Anemia, disturbed liver function tests and hypoalbuminemia were the most common pathologic laboratory findings. Salmonella serogroups B and D were isolated most frequently. The rate of positive blood cultures increased significantly during the years, as did resistance to ampicillin and trimethoprim-sulfamethoxazole. Salmonella infection has two peaks of incidence: at ages 1–5 and 15–65 years. Bacteremia was prominent in the extreme ages.

Conclusions: Salmonella infection has a different clinical presentation in different age groups. The significant increase in the rate of bacteremia in the extreme age groups necessitates a different attitude and management for these heterogeneous patient populations.
