Bilateral metastases to extraocular muscles from lobular breast carcinoma.

BACKGROUND: Metastastic carcinoma to extraocular muscles is extremely rare, but even more so is the case of a bilateral one. CASE REPORT: A 50-year-old woman with a history of mastectomy for a T4N1M0 right breast carcinoma was referred to us with diplopia due to bilateral extraocular muscle metastases, 5 years post mastectomy. Multiple metastases to the whole body were also present. A combination of high-dose irradiation, hormonotherapy and chemotherapy were performed. RESULTS: Despite the multidisciplinary treatment approach, the diplopia persisted. A literature review revealed only 4 cases of bilateral metastases to extraocular muscles. The present case is the second attributed to lobular carcinoma and the only one treated with a high dose of radiotherapy combined with systemic therapy. CONCLUSION: In a cancer patient, any orbital change must be examined for the possibility of an extraocular metastasis. Conclusions affecting the optimal treatment policy of extraocular muscle metastases are difficult to determine, due to the small number of reported cases.

Capsule endoscopy retention as a helpful tool in the management of a young patient with suspected small-bowel disease.

Capsule endoscopy is an easy and painless procedure permitting visualization of the entire small-bowel during its normal peristalsis. However, important problems exist concerning capsule retention in patients at risk of small bowel obstruction. The present report describes a young patient who had recurrent episodes of overt gastrointestinal bleeding of obscure origin, 18 years after small bowel resection in infancy for ileal atresia. Capsule endoscopy was performed, resulting in capsule retention in the distal small bowel. However, this event contributed to patient management by clearly identifying the site of obstruction and can be used to guide surgical intervention, where an anastomotic ulcer is identified.

Results of reconstruction of massive irreparable rotator cuff tears using a fascia lata allograft.

BACKGROUND: Despite the advances in surgical treatment options, massive rotator cuff (r-c) tears still represent a challenge for orthopedic surgeons. This study assesses the effectiveness of fascia lata allograft in reconstruction of massive and irreparable r-c tear and to evaluate the healing and functional outcomes. MATERIALS AND METHODS: 68 patients (38 men, 30 women, mean age 64.9 years) with massive or irreparable r-c tears were treated with placement of fascia lata allograft to fill the defect between February 2006 and February 2010. At 43 months followup they were evaluated clinically using the constant score, preoperatively and postoperatively. Magnetic resonance imaging (MRI) and ultrasound were used postoperatively, to assess the integrity of the allograft at the repair site. Postoperatively, standard rehabilitation protocol was followed with gradual restoration. RESULTS: Postoperative constant score increased from 32.5 preoperatively to 88.7 postoperatively. The most important was the pain relief from 2.4 preoperatively to 14.1 postoperatively and range of motion. The results of the MRI were not reliable, but the ultrasound was satisfactory. Finally, there was no infection or rejection of the graft in any of the patients. CONCLUSIONS: Despite advances in surgical methods, there is still not a universally accepted treatment for massive and irreparable rotator cuff tears, because the standard methods have dubious results, with excessive retear rates and poor outcomes, necessitating the need for new repair strategies. We documented significant clinical improvement using fascia lata allograft in the repair of massive irreparable r-c tear, acting as scaffold to bridge the defect, enhancing the healing at the repair site.

Fascia lata allograft bridging of a rotator cuff tear in a rabbit animal model.

PURPOSE: Despite advances in surgical treatment options, large rotator cuff (r-c) tears still represent a challenge for orthopedic surgeons. The purpose of this study was to evaluate the temporary and spatial histological incorporation of fascia lata allografts, used for bridging artificially created defects of the r-c. MATERIALS AND METHODS: Seventy-two rabbits were divided into two groups and a supraspinatus tendinous defect was created. Half of the rabbit population underwent repair only, while in the other half, the defect was bridged utilizing fascia lata allograft. The animals were euthanized at 2, 4, and 6 weeks postoperative. Half of the specimens were evaluated histologically and the other half underwent mechanical testing. RESULTS: There was an increased remodeling activity, fibroblastic in growth and strong presence of collagen fibers observed at 6 weeks on both groups. A gradually increasing mechanical strength was noticed by week 6 and increased toughness was also found at the same time period. There was no significant difference observed between the two groups regarding their histological and mechanical properties. CONCLUSIONS: In the difficult scenario of a large irreparable tear where the simple suture of the remaining r-c is impossible, allograft bridging, could be used with satisfactory results. CLINICAL RELEVANCE: Treatment Study, Level 1.

The Role of Virtual Cystoscopy, after Multidetector Computed Tomography Imaging Reconstruction without the Use of Contrast Medium, in the Diagnosis and Evaluations of Bladder Tumors: Preliminary Study.

Introduction. Although conventional cystoscopy is considered to be the gold standard for diagnosis and follow-up of bladder tumors, it remains an invasive and costly procedure. With the advent of the multidetector CT (MDCT) scanners supported by specialized software virtual cystoscopy (VC) is possible. We assess the role of VC in diagnosing and evaluating bladder lesions. Materials and Methods. Between September 2010 and October 2011, 25 consecutive patients with cystoscopically confirmed bladder tumor underwent VC. The radiologists involved in this prospective study were blinded to the exact findings. After draining any residual urine with a catheter, the bladder was retrogradely insufflated with 200-600 cc of air. No intravenous or intravesical contrast was used. MDCT scan was performed in supine and prone positions and three-dimensional reconstruction of the urinary bladder was performed. Results. The examination was well tolerated by all patients with no complications. In total, 43 lesions were detected both with conventional cystoscopy and VC. Tumor size measured by CT ranged from 3 to 80 mm in diameter. The pathological report revealed noninvasive transitional cell carcinomas in all cases. Conclusion. VC has promising results in detecting exophytic bladder lesions. In the future it could be part of the diagnostic algorithm for bladder tumors.

Extensive tumoral calcinosis in a patient with systemic sclerosis.

Tumoral calcinosis, a rare disease manifesting with periarticular, calcified masses in soft tissues, can be either primary or secondary to a disease, such as systemic sclerosis. In the case reported here, a patient diagnosed with systemic sclerosis presented with hard calcified masses that involved the shoulders and hips.

Phase II study of temozolomide and concomitant whole-brain radiotherapy in patients with brain metastases from solid tumors.

BACKGROUND: The aim of this study was to evaluate the effectiveness and possible toxicity of the combination of temozolomide (TMZ) with whole-brain irradiation (WBI) in the treatment of brain metastases from solid tumors. PATIENTS AND METHODS: 33 patients with brain metastases were included in the study and treated with TMZ 60 mg/m2/day (days 1-16) concomitantly with WBI (36 Gy/12 fractions given in 16 days). One month after the end of radiotherapy, 6 cycles of TMZ were administered as adjuvant treatment (200 mg/m2/day for 5 consecutive days every 28 days). RESULTS: Responses were assessed using computed tomography at the end of the 3rd and 6th cycle of chemotherapy. The objective response rate was 54.5% and 57.6% after the 3rd and the 6th cycle, respectively. The median overall survival was 12 months. In patients with metastases from lung cancer the objective response rate was 11/14 (78.6%) after both the 3rd and the 6th cycle of treatment. The most common side effects were anemia (24.2%), thrombocytopenia (18.2%), as well as nausea and vomiting (18.2%). The high incidence of hepatotoxicity (45.5%) might be related to concomitantly administered antiepileptic drugs and not to TMZ. CONCLUSION: WBI combined with TMZ as concomitant and adjuvant treatment is effective in treating brain metastases, with acceptable mild side effects.

Solitary brain metastasis from classic biphasic pulmonary blastoma: a case report and review of the literature.

BACKGROUND: Classic biphasic pulmonary blastoma (CBPB) is a rare and aggressive primary malignancy, brain metastases of this type of tumor are even rarer. CASE REPORT: A 51-year-old male patient with a solitary cerebral metastasis, diagnosed ten months after left pneumonectomy for a CBPB, was treated by surgery and accelerated hypofractionated radiotherapy. RESULTS: The patient died 15 months after partial removal of the brain metastasis. Literature review revealed only 4 cases of solitary brain metastases from this type of malignancy. The present case is the second one reported with a combined treatment of surgery and radiotherapy resulting in the longest survival. CONCLUSION: The best treatment for CBPB is difficult to determine because of the small number of cases, however, the combination of surgery with radiotherapy seems to be effective. The effectiveness of chemotherapy has not been ascertained.

Isolated talus metastasis from breast carcinoma: a case report and review of the literature.

BACKGROUND: Acrometastases are very rare and have been identified in only a few cases on the foot. At the onset, they might be misdiagnosed as arthritis. CASE REPORT: A 59-year-old woman with isolated metastasis to the talus, originating from breast carcinoma was treated by radiotherapy, letrazole, and intravenous bisphosphonates. RESULTS: The review of the literature revealed that this is the first case of an isolated metastasis to the bone of talus from a breast carcinoma, while there are a few cases originating from other organs. The differential diagnosis of acrometastases may be difficult. CONCLUSION: Pain in the foot or hand of a patient with a known history of malignancy should be considered as potential metastasis.
