Background: Atopic dermatitis or atopic eczema is an itchy inflammatory skin condition with a predilection of the skin flexures. Most cases start in children although some have been reported in adults. Patients with moderate to severe disease refractory to topical corticosteroid or calcineurin inhibitors may require second-line treatment such as phototherapy or systemic immunosuppressants. Methotrexate therapy has been suggested to be a useful immunosuppressant in adult atopic dermatitis.

Objectives: To further determine the efficacy of low dose methotrexate therapy in adults with new-onset atopic dermatitis or with idiopathic eczema.

Methods: All adult patients with new-onset atopic dermatitis or idiopathic eczema treated by methotrexate in our clinics from 2004 to 2006 were included in the study. All had failed prolonged therapy with oral antihistamines and local corticosteroid creams. Methotrexate, 10–20 mg, was given orally once a week along with folic acid supplements 5 days a week. Additional therapies included predominantly emollients. During the entire treatment period the investigators made global assessments of the clinical response.

Results: Nine patients diagnosed with late-onset atopic dermatitis (n=6) or idiopathic eczema (n=3) were treated with methotrexate. All patients responded to the drug. The initial response was noted after 3–7 weeks. Six patients achieved complete remission after 3 months of methotrexate therapy and three patients had significant improvement. One patient's the condition worsened after achieving a complete response while on methotrexate and it was withdrawn completely. No serious adverse events were noted during treatment.

Conclusions: Low dose methotrexate is an effective therapeutic alternative for late-onset atopic dermatitis or idiopathic eczema in patients unresponsive to local and other systemic therapies.
 

Background The temporal behavior of the coronary microcirculation in acute myocardial infarction may affect outcome. Diastolic deceleration time and early systolic flow reversal derived from coronary artery blood flow velocity patterns reflect microcirculatory function.

Objectives To assess left anterior descending coronary artery flow velocity patterns using Doppler transthoracic echocardiography after primary percutaneous coronary intervention, in patients with anterior AMI[1].

Methods Patterns of flow velocity patterns of the LAD[2] were obtained using transthoracic echocardiography-Doppler in 31 consecutive patients who presented with anterior AMI. Measurements were done at 6 hours, 36–48 hours, and 5 days after successful PPCI[3]. Measurements of DDT[4] and pressure half times (Pt½), as well as observation for ESFR[5] were performed.

Results In the first 2 days following PPCI, the average DDT, 600 ± 340 msec, were shorter than on day 5, 807 ± 332 msec (P < 0.012). FVP[6] in the first 2 days were dynamic and bidirectional: from short DDT (< 600 msec) to long DDT (> 600 msec) and vice versa. On day 5 most DDTs became longer. Pt½ at 6 hours was not different than at day 2 (174 ± 96 vs. 193 ± 99 msec, P = NS) and became longer on day 5 (235 ± 98 msec, p = 0.012). Bidirectional patterns were also observed in the ESFR in 6 patients (19%) at baseline, in 4 (13%) at 36 hours, and in 2 (6.5%) on day 5 after PPCI.

Background: Occult breast cancer without clinically or mammographically detectable breast tumor is an uncommon presentation.

Objectives: To assess the role of breast MRI in women with metastatic carcinoma and an occult primary, and to define the MRI characteristics of the primary breast tumor.

Methods: This retrospective study evaluated 20 women with metastatic carcinoma of unknown origin who underwent breast MRI between 2000 and 2006. Four women were excluded, leaving 16 in the study group. Probability of malignancy was assessed according to BIRADS classification. MRI performance in detecting lesions and evaluating disease extent was assessed, with the gold standard being surgical or biopsy pathology.

Results: MRI detected suspicious lesions in 15 patients. Lesion size ranged from 0.4 to 7 cm (median 1.5 cm). MRI detected a single lesion in 6 patients (40%), multifocal disease in 3 (20%), multicentric disease in 4 (27%), and bilateral breast lesions in 2 (13%). In 13 patients MRI depicted the primary breast cancer. Initial treatment was surgical in nine; MRI correctly estimated disease extent in 6 (67%), underestimated disease extent in 1 (11%), and overestimated it in 2 (22%). Four patients had biopsy followed by chemotherapy; one had multicentric disease and one had multifocal disease. MR findings were false positive in two patients and false negative in one.

Conclusions: MRI is sensitive in detecting the primary tumor and beneficial in assessing tumor extent. Small size and multiple foci are common features. We suggest that bilateral breast MRI be part of the evaluation of women with metastatic carcinoma and an occult primary.
 

Background: Idiopathic frozen shoulder is a self-limiting regional skeletal problem of unknown etiology. Clinically, patients first experience a phase of pain, progressing to a freezing stage when glenohumeral motion is lost, followed by a thawing phase when pain gradually subsides and most of the lost motion returns.

Objectives: To identify possible specific and non-specific risk factors for idiopathic frozen shoulder.

Methods: We compared the medical histories, drug treatment, previous hospital as well as health management organization blood tests of 126 new consecutive frozen shoulder patients from a shoulder clinic to those of an age-matched control group of 98 consecutive patients from an orthopedic foot and ankle clinic and to the regional population disease prevalence registry. Frozen shoulder was classified as idiopathic only if there was no history of trauma and no evidence of a rotator cuff tear.

Results: Among the frozen shoulder patients 29.4% had diabetes and 13.5% had thyroid disorders. The risk ratio for diabetes in the frozen shoulder group was 5.9 for males (95% confidence interval 4.1–8.4, P < 0.001) and 5.0 for females (95% CI[1] 3.3–7.5, P < 0.001). The risk ratio for thyroid disorders among females with frozen shoulder was 7.3 (95% CI 4.8–11.1, P = 0.001). No significant difference was found in the prevalence of thyroid disorders between frozen shoulder and the control group, but there was a significantly higher prevalence of diabetes in males and a trend for higher prevalence in females in the frozen shoulder group.

Conclusions: Physicians should be aware that diabetes is a specific risk factor for idiopathic frozen shoulder in both males and females and thyroid disorders are a non-specific risk factor in females only.  

Background: Studies have found ethno-cultural disparities in health care delivery in different countries. Minority populations may receive lower standards of care.

Objectives: To test a hypothesis that Jewish Ethiopian women may be receiving less preventive recommendations than other women in Israel.

Methods: A telephone survey was conducted using a structured questionnaire designed specifically for this study in Hebrew, Russian and Amharic (Semitic language of Ethiopia). The study group included 51 post-menopausal women of Ethiopian origin, aged 50–75. The control group included 226 non-Ethiopians matched by age, some of whom were immigrants from the former Soviet Union. The questionnaire dealt with osteoporosis and breast cancer screening and prevention.

Results: All the parameters measured showed that the general population received more preventive treatment than did Jewish Ethiopian women, including manual breast examination, mammography, osteoporosis prevention, bone density scans, and recommendations for a calcium-rich diet, calcium supplementation, hormone replacement therapy, biphosphonates and raloxifen. On a logistic regression model the level of knowledge of the Hebrew language, age, ethnicity and not visiting the gynecologist were significantly related to not having received any preventive medicine recommendations.
Conclusions: Differences in cultural backgrounds and language between physicians and their patients may become barriers in the performance of screening and preventive medicine. Recognizing this potential for inequity and using methods to overcome these barriers may prevent it in the future

Background: The degree of left ventricular dysfunction determines the prognostic outcome of patients with acute myocardial infarction.

Objectives: To define the clinical, angiographic and procedural variables related to LV[1][1] dysfunction in patients with  with anterior wall AMI[1][2] referred for primary percutaneous coronary intervention.

Methods: The sample included 168 patients treated by primary PCI[1][3] for first anterior wall AMI. Clinical, demographic and medical data were collected prospectively into a computerized registry, and clinical outcome (death, reinfarction, major cardiovascular event) were evaluated during hospitalization and 30 days after discharge. Patients were divided into three groups by degree of LV dysfunction (mild, moderate, severe) and compared for clinical, angiographic and procedural variables.

Results: LV dysfunction was associated with pre-PCI renal failure (serum creatinine > 1.4 mg/dl), peripheral vascular disease, high peak creatine kinase level, longer door to balloon time, low TIMI flow grade before and after PCI, and use of an intraaortic balloon pump. On multivariate analysis adjusted for baseline differences, peak creatine kinase level (r = 0.3, P = 0.0001) and door to needle time (r = 0.2, P = 0.008) were the most significant independent predictors of moderate or severe LV dysfunction after anterior AMI.

Conclusion: Abnormal LV function after first anterior AMI can be predicted by door to balloon time and the size of the infarction as assessed by creatine kinase levels. Major efforts should be made to decrease the time to myocardial reperfusion.

Objectives: To determine whether reliable data could be obtained at lower cost.

Methods: The study sample consisted of 50 patients with mild to severe stable COPD]1[. All underwent pulmonary function test and the cardiopulmonary exercise test, 6 minute walk and 15 step exercise oximetry test as part of their regular follow-up visit. Functional capacity was graded according to each test separately and the functional capacities obtained were correlated.

Results: The results showed that most of the patients had severe COPD according to pulmonary function tests (mean forced expiratory volume in the first second 46.3 ± 19.9% of predicted value). There was a good correlation between the cardiopulmonary exercise test and the 6 minute walk functional capacity classes (r = 0.44, P = 0.0013). We did not find such correlation between the 15 step exercise oximetry test and the cardiopulmonary exercise test (r = 0.07, P = 0.64).

Conclusions: The study shows that the 6 minute walk is a reliable and accurate test in the evaluation of functional capacity in COPD patients.
