Background: Ultrasound is useful in detecting acromioclavicular pathologies in cases of trauma, inflammations and degenerative changes.

Objectives: To describe the sonographic findings of the acromioclavicular joint pathology in patients with anterior shoulder pain.

Methods: Sonographic examination of the ACJ[1] was used to examine 30 adults with anterior shoulder pain. As a control group we studied 30 asymptomatic patients and compared the findings to plain radiographs of the symptomatic group.

Results: The pathologic findings consisted of swelling of the joints, bone irregularities, widening and/or narrowing of the ACJ, soft tissue cyst formation, excessive fluid collection, and calcification. All these signs represent degenerative changes compatible with early osteoarthritis. We encountered one case of septic arthritis that required joint aspiration and antibiotic treatment.

Conclusions: It is our belief that ultrasonography should be used routinely in cases of anterior shoulder pain since it demonstrates various pathologies undetected by plain radiographs.

Background: Heterotopic ossification is a common complication of hip surgery and musculoskeletal or brain traumas.

Objectives: To confirm by in vivo study that colchicine inhibits osteoblast cell proliferation with marked decrease in tissue mineralization.

Methods: Heterotopic ossification was induced in three groups of New Zealand white rabbits (females, 6 months old, weight 3–3.5 kg) by injecting 2 ml bone marrow drawn from the iliac crest into their right thigh muscle. To prevent heterotopic ossification, colchicine (0.25 mg/day) was administered orally for 4 weeks to two groups of adult rabbits: group A (preload group) – 1 week preceding bone marrow injection; group B – on day of injection; and group C – control group.

Results: After 4 weeks the rabbits were evaluated by radiographs and ultrasound for evidence of heterotopic ossification. At the end of the study histologic samples were taken from all the thighs. Imaging and histologic studies showed, with statistical significance, almost complete prevention of heterotopic ossification formation in group A (preload) and a marked decrease in group B, when compared with the controls in whom large new bone had formed at the injection site. These results indicated the inhibitory effects of colchicine on a bone-forming process in soft tissue such as heterotopic ossification.

Conclusions: The role of colchicine in preventing heterotopic ossification in other bone-forming conditions, such as hip arthroplasty or pelvic trauma, and after brain trauma, remains to be evaluated in a clinical setting.

Various events occurring during pregnancy might influence the normal neurogenesis of fetus brain, including exposure to the influenza virus. Several studies have attempted to find a relationship between exposure to influenza virus and the onset of schizophrenic behavior in childhood or adulthood, however results remain contradictory. In this review we describe several animal and human studies that show or do not show a relationship between exposure to the influenza virus during pregnancy and the subsequent development of schizophrenia.

Background: In patients with Graves’ ophthalmopathy, orbital decompression surgery is indicated for compressive optic neuropathy, severe corneal exposure, or for cosmetic deformity due to proptosis. Traditionally this has been performed through a transantral approach, but the associated complication rate is high. More recently, endoscopic orbital decompression has been performed successfully with significantly fewer postoperative complications.

Objective: To report our experience of endoscopic orbital decompression in patients with severe Graves’ ophthalmopathy.

Methods: Three patients (five eyes) underwent endoscopic orbital decompression for Graves’ ophthalmopathy at Soroka Medical Center between the years 2000 and 2002. The indications for surgery were compressive optic neuropathy in three eyes, severe corneal exposure in one eye, and severe proptosis not cosmetically acceptable for the patient in one case. An intranasal endoscopic approach with the removal of the medial orbital wall and medial part of the floor was performed.

Results: In all five eyes an average reduction of 5 mm in proptosis was achieved. Soon after surgery, visual acuity improved in the three cases with compressive optic neuropathy, and exposure keratopathy and cosmetic appearance improved. The diplopia remained unchanged. No complications were observed postoperatively.

Conclusions: Endoscopic orbital decompression with removal of the medial orbital wall and medial part of the floor in the five reported eyes was an effective and safe procedure for treatment of severe Graves’ ophthalmopathy. A close collaboration between ophthalmologists and otorhinolaryngologists skilled in endoscopic sinus surgery is crucial for the correct management of these patients.

Background: An estimated 10% of all children are subject to recurrent attacks of abdominal pain of unknown origin. When no organic cause is found, the working diagnosis is usually functional abdominal pain.

Objectives: To investigate the possible causative role of occult constipation.

Methods: We defined occult constipation as the absence of complaints of constipation on initial medical history or of symptoms to indicate the presence of constipation. The diagnosis was made by rectal examination and/or plain abdominal X-ray.

Results: Occult constipation was found to be the cause of RAP[1] in 42.6% of children examined. Treatment consisted of paraffin oil and phosphate enema. In 82.84% of cases the abdominal pain subsided considerably or disappeared within 2 weeks to 3 months of treatment. On telephone interview of the parents at 1–1.5 years after discharge, 96.5% reported that both the abdominal pain and constipation had subsided or disappeared.

Conclusions: Occult constipation can be easily identified and treated in a large number of children with RAP who were diagnosed as having functional abdominal pain.

Background: Preoperative radiotherapy is standard treatment for rectal cancer and is often combined with 5-fluorouracil-based chemotherapy. UFT, a new oral 5FU[1] derivative, given daily during a course of radiotherapy mimics the effect of continuous-infusion 5FU.

Objectives: To determine the maximum tolerated dose of oral UFT and leucovorin with preoperative pelvic irradiation for rectal cancer, and assess tumor response.

Methods: In this phase 1 trial, 16 patients aged 42–79 years with tumors within 12 cm of the anal verge received radiotherapy, 45 Gy over 5 weeks, an escalating dose of oral UFT, and a fixed dose of 30 mg/day leucovorin. UFT and leucovorin were given for 28 consecutive days concomitant with the first 4 weeks of radiotherapy. Surgery was scheduled for 4–6 weeks after completion of radiotherapy. The surgical procedure was determined by the surgeon at the time of surgery.

Results: No grade III toxicity was seen at 200 mg/m²/day UFT. Of eight patients who received 240 mg/m²/day UFT, one developed grade IV diarrhea; of four patients who received 270 mg/m²/day UFT, one was hospitalized with grade IV diarrhea and leukopenic fever and died during hospitalization. Of the 15 evaluable patients, 9 had pathologic tumor down-staging including 4 patients with complete response. Only one patient required a colostomy.
Conclusions: The MTD[2] of UFT together with leucovorin and preoperative radiotherapy for rectal cancer is 240 mg/m². The major toxicity was diarrhea. Down-staging was noted in 60% of patients, allowing sphincter-preserving surgery even in patients with low tumors.

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: Hyperthermia combined with radiation therapy was shown to be more effective in local recurrent breast cancer than radiotherapy alone, but it use is limited due to technical difficulties, stringent reimbursement policies and because it is time consuming.

Objectives: To report our experience with a simple and convenient XRT+HT[1] delivery system.

Methods: XRT was delivered through either electron or photon beams (total dose 30–40 Gy in previously irradiated fields or 50–70 Gy in non-irradiated fields). Hyperthermia was delivered by a dedicated HT device operating at 915 MHz. The heating session lasted 45 minutes. The maximal tumor surface temperature was set at 45°C and modified according to patient comfort. No intratumoral (invasive) thermometry was used. At least two HT sessions were scheduled to each HT field during the entire XRT treatment period. Tumor response was evaluated every 3 months after completion of treatment. The overall survival was measured from XRT+HT initiation until the last follow‑up.

Results: Fifteen women underwent 114 HT treatments delivered through 28 HT fields. Twenty-four HT fields (15 patients) were previously irradiated. There was complete infield response in 10 fields (6 patients), partial response in 8 fields (4 patients), no response or progressive disease in 4 fields (3 patients), and no parameters in 6 fields (5 patients). Eighteen (64%) fields had complete or partial response. Seven patients had outfield recurrence despite wide XRT+HT fields. Ulceration was the only major side effect (three patients, three fields).

Conclusions: The combined HT+XRT delivery system, with no invasive thermometry, is a simple and effective method for treating local recurrent breast cancer.
