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.  

Objectives: To examine whether hostility, anxiety and autobiographical memory (a correlate of depression) are associated with IIH[1].

Methods: Using a case-control cross sectional design, 20 patients with IIH were compared with 9 healthy controls of similar age, weight and height, and 11 headache controls. Patients were assessed for hostility and anxiety. The Autobiographical Memory Test was used to assess episodic memories.

Results: The IIH group reported significantly more anxiety and more general episodic memories than the healthy controls, but not the headache control group. The headache control patients reported more general memories than did the healthy controls.

Conclusions: Patients with headaches, whether of general origin or related to IIH, have a poor psychosocial profile. While the study design does not permit any conclusions regarding causality, our results support the need to consider psychological factors in evaluating and treating IIH and headache patients.

Objectives: To compare the outcomes of two groups of CICF[1] patients who underwent two different treatment protocols.

Methods: The study cohort included 72 infants treated in our hospital from August 1998 to December 2002. Group 1 comprised 40 infants (61 clubfeet) who were treated by a traditional method (a modification of the Kite and Lovell technique), and group 2 consisted of 32 infants (48 clubfeet) who were treated with the Ponseti technique. Both groups were similar in age, gender and severity of the deformity (Dimeglio scoring system)

Results: After an average follow-up of 54.9 months (range 44–68), 35 (57%) clubfeet in group 1 required surgical intervention and 27 (44%) clubfeet had a residual deformity at last follow-up. In the Ponseti group, 45 (94%) clubfeet were fully corrected at last follow-up (average 29.2 months, range 16–45) while 3 (6%) clubfeet had residual deformity and required surgery. Tendo-Achilles tenotomy was performed with no complications in 47 clubfeet (in group 2) at an average age of 2.4 months (range 2–4 months).

Conclusions: Even after a relatively short follow‑up period, our success rate with the Ponseti approach already appears to be significantly higher and to bear fewer complications than the traditional treatment, in agreement with the results published by other medical centers. We now endorse the Ponseti technique of conservative manipulative treatment for congenital idiopathic clubfoot in our department.

Background: Adhesive capsulitis, also termed “frozen shoulder,” is controversial by definition and diagnostic criteria that are not sufficiently understood. The clinical course of this condition is considered as self-limiting and is divided into three clinical phases. Several treatment methods for adhesive capsulitis have been reported in the literature, none of which has proven superior to others.

Objectives: To evaluate the long-term follow-up of patients with idiopathic adhesive capsulitis who were treated conservatively.

Methods: We conducted a long-term follow-up (range 5.5–16 years, mean 9.2 years) of 54 patients suffering from idiopathic adhesive capsulitis. All patients were treated with physical therapy and non-steroidal anti-inflammatory drugs.

Results: An increased statistically significant improvement (P < 0.00001) was found between the first and last visits to the polyclinic in all measured movement directions: elevation and external and internal rotation.

Conclusions: Conservative treatment (physical therapy and NSAIDs[1]) is a good long-term treatment regimen for idiopathic adhesive capsulitis.

Background: Idiopathic left ventricular tachycardia with a right bundle branch block configuration and left axis deviation, first described by Belhassen et al., is a rare electrocardiographic-electrophysiologic entity. Radiofrequency catheter ablation has been proposed as a good therapeutic option, but the best criteria for determining the optimal site of ablation are still under debate.

Objectives: To report the clinical features, electrophysiologic characteristics, results of RFA[1], and long-term outcome in 18 patients with "Belhassen's VT” treated in our laboratory during the last 10 years, stressing the best electrophysiologic criteria for determining the optimal site of ablation.

Methods: Eighteen consecutive patients with this specific VT[2] underwent RFA in our laboratory during the last 10 years. RFA was acutely successful in 17 patients after one or two procedures (15 and 2 patients, respectively) using 4.1 ± 2.2 RF pulses. The putative ablation sites were defined by good pace-mapping (3 patients), earliest recorded Purkinje spike prior to the QRS onset during VT or sinus rhythm (6 patients), earliest endocardial activation during VT (1 patient), and diastolic potential preceding the Purkinje spike during VT and/or late diastolic potential in sinus rhythm (7 patients). In the patients with a definite successful ablation, the ratio of successful to unsuccessful radiofrequency pulse delivery to the diastolic potential site was compared to that of other methods. The ratio of successful RFA at the diastolic potential site (5:8) was higher than in the other methods (8:31), and the difference was statistically significant (P = 0.05). Successful ablation sites were more basal when the diastolic potential site was chosen.

Conclusion: The results of the present study confirm the high success rate and safety of RFA using conventional techniques in the management of “Belhassen VT,” suggesting that this procedure can be proposed as a first-line therapy. Ablating at a site demonstrating a late diastolic potential is at least as effective as ablating at a ventricular exit site, although the use of combined electrophysiologic criteria may be the optimal approach.

Diffuse idiopathic skeletal hyperostosis is often incorporated into osteoarthritis. Although DISH[1] often coexists with OA, patients affected by this disorder differ from patients with primary OA in several aspects: prevalence in the general population, gender distribution, anatomic site of primary involvement, magnitude and distribution in the spine and the peripheral joints. DISH is a distinct clinical entity. Its recognition as such should stimulate clinicians and researchers to focus on its pathogenesis, treatment and prevention.
