Background: Testicular torsion associated with undescended testis is uncommon but requires immediate treatment. Ultrasound Doppler is recognized as the preferred imaging modality for testicular torsion due to its high specificity, sensitivity and availability.

Objectives: To determine the accuracy of ultrasound Doppler in diagnosis of torsion of undescended testis.

Methods: We describe three patients with known undescended testis who were admitted with groin pain and had preoperative ultrasound Doppler. The discrepancy between these and the intraoperative findings is discussed.

Results: In two patients incarcerated inguinal hernia was diagnosed with ultrasound Doppler; however, surgery revealed torsion of an undescended testis. In the third patient ultrasound Doppler diagnosed torsion of undescended testis, but at surgery incarcerated inguinal hernia was found, without evidence of testicular torsion.

Conclusions: Torsion of undescended testis should be a clinical rather than radiologic diagnosis.
 

Background: The significance of arrhythmia occurring after successful recanalization of an occluded artery during treatment following primary percutaneous coronary intervention for ST-segment elevation myocardial infarction is controversial.

Objectives: To study the association of reperfusion arrhythmia with short and long-term survival.

Methods: We used a prospective registry of consecutive STEMI[1] patients undergoing PPCI[2]. Patients with an impaired epicardial flow (TIMI flow grade < 3) at the end of the procedure were excluded.

Results: Of the 688 patients in the study group, 22% were women. Mean (± SD) age of the cohort was 61 (± 14) years and frequent co-morbidities included diabetes mellitus (25%), dyslipidemia (55%), hypertension (43%) and smoking (41%). RA[3] was recorded in 200 patients (29%). Patients with RA had lower rates of diabetes (16% vs. 30%, P < 0.01) and hypertension (48% vs. 62%, P < 0.01), and a shorter median pain-to-balloon time (201 vs. 234 minutes, P < 0.01) than patients without RA. Thirty day mortality was 3.7% and 8.3% for patients with and without RA, respectively (P = 0.04). After controlling for age, gender and pain-to-balloon time the hazard ratio for mortality for patients with RA during a median follow-up period of 466 days was 0.46 (95% confidence interval 0.23–0.92).

Conclusions: The occurrence of RA immediately following PPCI for acute STEMI is associated with better clinical characteristics and identifies a subgroup with a particularly favorable prognosis.

Objectives: To estimate the influence of phlebotomies on large artery (C1) and small artery compliance (C2) in PV patients by using non-invasive methods.

Methods: Short-term hemodynamic effects of phlebotomy were studied by pulse wave analysis using the HDI-Pulse Wave CR2000 (Minneapolis, MN, USA) before and immediately after venesection (300–500 ml of blood). We repeated the evaluation after 1 month to measure the long-term effects.

Results: Seventeen PV patients were included in the study and 47 measurements of arterial compliance were performed: 37 for short-term effects and 10 for long-term effects. The mean large artery compliance (C1) before phlebotomy was 12.0 ml/mmHg x 10 (range 4.5–28.6), and 12.6 ml/mmHg x 10 (range 5.2–20.1) immediately after phlebotomy (NS). The mean small artery compliance (C2) before and immediately after phlebotomy were 4.4 mg/mmHg x 10 (range 1.2–14.3) and 5.5 mg/mmHg x 10 (range 1.2–15.6) respectively (delta C2–1.1, P < 0.001). No difference in these parameters could be demonstrated in the long-term arm.

Conclusions: Phlebotomy immediately improves arterial compliance in small vessels of PV patients, but this effect is short lived.

Objectives: To evaluate the national Israeli experience with lung transplantation in patients with CF[1].

Methods: We reviewed the medical charts of all CF patients who underwent lung transplantation between January 1996 and June 2005 at the two Israeli centers that performed this procedure.

Results: Eighteen transplantations were performed in 17 patients. Mean patient age at transplantation was 25.3 ± 9.1 years, and mean duration of follow-up in survivors (n=14) was 37.2 months (range 1–113 months). The actuarial survival rate was 88% at 1 year and 74% at 5 years. Pulmonary function, expressed as percent of predicted normal forced expiratory volume in 1 sec, improved from 22.4 ± 8.1% to 76 ± 16.8% at one year after transplantation. Bronchiolitis obliterans syndrome was diagnosed in 5 patients (29%), of whom 2 died and 2 are currently candidates for retransplantation. Median time to onset of BOS[2] was 34.2 months (range 17–64 months).

Conclusion: In Israel, the early and intermediate-term results of lung transplantation for cystic fibrosis are encouraging. BOS remains a major complication that threatens long-term outcome.

Background: Heat shock proteins are highly conserved immunodominant antigens found in various species. Humoral immune responses to mycobacterial HSP65[1] and human HSP60 have been established in a number of human autoimmune diseases.

Objective: To assess the prevalence of antibodies to HSP60 kDa and HSP65 kDa in patients with Sjogren's syndrome as compared to normal subjects.

Methods: Thirty-seven patients with SS[2] were compared with normal controls. The antibodies against human HSP60 were measured by the Anti-Human (IgG/IgM) HSP60 ELISA kit. IgGs[3] and IgMs to mycobacterial HSP65 were determined using an enzyme-linked immunosorbent assay with mycobacterial recombinant HSP65 antigens.

Results: The levels of both anti-HSP60 and -HSP65 were lower among patients compared with controls. IgG autoantibodies to HSP60 were significantly different between groups: 162 ± 55.1 ng/ml in controls versus 112.3 ± 30.6 ng/ml in SS patients (P < 0.001). The levels among controls of anti-HSP65 IgM isotype were also significantly higher than among patients: 111.6 ± 33.4 U/ml versus 96.1 ± 8.9 U/ml (P = 0.01).

Conclusions: The results of the present study show that the levels of different isotypes of anti- HSP60 and HSP65 antibodies were lower in patients with SS than in normal subjects. Additional studies on larger patient populations are required to evaluate the prevalence of these autoantibodies in SS patients.

Background: Food allergies in children are often very serious and can lead to anaphylactic reactions. Observations that camel milk ameliorates allergic reactions were noted over the years. The effect of the camel milk is probably related to its special composition.

Objectives: To investigate the effect of camel milk in several children with severe food (mainly milk) allergies.

Methods: We studied eight children with food allergies who did not benefit from conventional treatment. Their parents, or their physicians, decided to try camel milk as a last resort. The parents were advised by the authors – who have considerable experience with the use of camel milk – regarding how much and when the children should drink the milk. The parents reported daily on the progress of their children.

Results: All eight children in this study reacted well to the milk and recovered fully from their allergies.

Conclusions: These encouraging results should be validated by large-scale clinical trials.
