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.  

Capsule endoscopy was launched at the beginning of this millennium and has since become a well‑established tool for evaluating the entire small bowel for manifold pathologies. CE[1] far exceeded our early expectations by providing us with a tool to establish the correct diagnosis for such elusive gastrointestinal conditions as obscure gastrointestinal bleeding, Crohn's disease, polyposis syndrome and others. Recent evidence has shown CE to be superior to other imaging modalities – such as small bowel follow‑through X-ray, colonoscopy with ileoscopy, computerized tomographic enterography, magnetic resonance enteroclysis and push enteroscopy – for diagnosing small bowel pathologies. Since the emergence of CE, more than 500,000 capsules have been swallowed worldwide, and more than 700 peer-reviewed publications have appeared in the literature. This review summarizes the essential data that emerged from these studies.

Objectives: To examine the effect of postoperative loco-regional radiotherapy on local and regional recurrence and survival in breast cancer patients with four or more involved lymph nodes or extracapsular tumor extension.

Methods: This controlled clinical trial included 258 breast cancer patients with four or more involved nodes or ECE[1]. Eighty-nine patients in the control group had modified radical mastectomy and received adjuvant chemotherapy with melphalan and 5FU, but no radiation therapy. The 169 patients in the study group (87 with MRM[2] and 82 with lumpectomy and axillary dissection) received various adjuvant chemotherapy regimes and radiation therapy to the chest wall/breast, supraclavicular region and full axilla.

Results: With an average follow-up of more than 5 years, loco-regional radiation significantly reduced local and regional disease recurrence. The median disease-free survival was significantly longer in radiated patients (59.2 months and 63.3 months in the MRM and L+AXLND[3] groups, respectively, vs. 28.4 months in the control group; P < 0.01). There was no difference in the rate of systemic recurrence and overall survival. The median overall survival was 71.2 and 67.5 months in the study groups (MRM and L+AXLND, respectively) and 70.5 months in the control group (P = 0.856).

Conclusions: Radiotherapy to the breast/chest wall and to the draining lymphatics, in addition to surgery and adjuvant therapy, significantly reduced the risk of local and regional recurrence in high risk breast cancer patients with four or more involved lymph nodes or ECE.

Objectives: To describe the role of wireless capsule endoscopy in diagnosing isolated small intestinal Crohn’s disease in two adolescents.

Methods: Wireless capsule endoscopy was performed in two adolescents with severe protein-losing enteropathy and negative standard diagnostic workup.

Results: Wireless capsule endoscopy successfully diagnosed Crohn’s disease with uncharacteristic presentations and negative radiographic and endoscopic findings in both patients.

Conclusions: The non-invasiveness and ease in performance of capsule endoscopy on an ambulatory basis make this diagnostic modality especially advantageous for children.

Background: During ingestible capsule endoscopy, video images are recorded throughout the device's natural propulsion through the digestive system. Shortening the transit time of the wireless video capsule through the stomach and small bowel could reduce the time needed to read and analyze the resultant images, utilize more effectively the short life of the capsule battery (7 ± 1 hours) and make it possible to image the entire small bowel.

Objective: To measure gastric and small bowel transit times, with and without preparation, using capsule endoscopy.

Methods: Capsule transit times through the stomach, small bowel and colon were evaluated by analysis of the videos generated during the capsule's passage. The study group included 62 patients with small and large bowel pathologies (e.g., iron deficiency anemia, Crohn's disease). The patients were divided into three groups: prepared with polyethylene glycol (Group A, n = 9), prepared with sodium phosphate (Group B, n = 13), and with no preparation (Group C, n = 40).

Results: The gastric emptying times were 20.4 ± 15.2 minutes in group A, 55.7 ± 45.1 in group B, and 48.3 ± 28.7 in group C (P = 0.01). The capsule produced views of the cecum in only 49 of the 62 patients. The mean small bowel transit time for these 49 patients was 238.8 ± 82.1 minutes, making the mean times for the groups (A,B,C) 148.9 ± 32.6, 289.4 ± 77.2 and 249.3 ± 73.9 minutes respectively (P = 0.0001).

Conclusion: Compared to both SP[1] and no preparation, preparation of the colon with PEG[2] significantly shortened the transit time of the capsule through the stomach and small bowel.

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.
