Acute respiratory distress following fine needle aspiration of thyroid nodule: case report and review of the literature.

BACKGROUND: Fine needle aspiration (FNA) is a widely used practice to assess thyroid lesions, with a low morbidity rate. Although neck hematomas following this procedure are quite common, only three cases of massive hemorrhage causing acute airways obstruction have been previously described. CASE REPORT: We report the case of a 74 years old female with acute respiratory distress following ultrasound-guided FNA for a right paraisthmic thyroid nodule. The patient was admitted to the Emergency Room (ER) 6 hours after the procedure with a large neck hematoma compressing the cervical trachea and requiring surgical decompression. Patient underwent endotracheal intubation followed by isthmectomy and evacuation of the hematoma. Extubation was made 24 hours later in the Intensive Care Unit and the patient was discharged after 48 hours uneventfully. CONCLUSIONS: Acute thyroid hemorrhage following FNA is very rare but still possible. Prompt intervention is mandatory for patients with rapidly evolving symptoms.

[Burkitt's lymphoma of the caecum in a patient with AIDS: clinical case and review of the literature]. / Linfoma di Burkitt del cieco in paziente con AIDS conclamato: caso clinico e revisione della letteratura.

Overall, lymphomas of the gastrointestinal tract are rare, although they are the most frequent extranodal location. The incidence of primary colic lymphoma, above all in the non-Hodgkin variant, is clearly higher in the HIV positive population, especially in subjects with AIDS. The authors present the case of a 51-year-old patient with AIDS undergoing antiviral therapy; he was suffering from abdominal pain and presented a palpable mass in the right iliac fossa; diagnosis was caecal non-Hodgkin lymphoma (NHL); radical right hemicolectomy was carried out with definitive histological diagnosis of Burkitt-type small cell NHL. The NHL of the colon represents no more than 1.2% of all malignant cancers of this part of the intestinal tract. Nevertheless such cases are comparatively frequent in patients with HIV virus, especially in the active phase and clinically proven to be due to immunodeficient syndrome. Of cardinal importance is the differential diagnosis between primary and secondary forms because of the different treatment and prognosis. Frequently such forms are observed in patients with AIDS, at advanced stages and with differentiated and hence more aggressive histotypes, also because they are present in organisms weakened by the underlying disease and by immunodeficiency. Primary NHLs of the colon are relatively frequent and aggressive in patients with AIDS; early diagnosis and treatment are therefore of fundamental importance to improve the oncological outcome for these patients.

[Accessory liver. Report of 2 cases]. / Le foie accessoire. Présentation de deux cas.

Two cases of ectopic liver tissue in patients submitted to an elective cholecystectomy for gallstones cholecystitis are reported. In the literature most part of cases are revealed as an uncommon cause of abdominal pain. A better definition of ectopic liver tissue versus accessory lobes is made.

Hypofractionation in prostate cancer: radiobiological basis and clinical appliance.

External beam radiation therapy with conventional fractionation to a total dose of 76-80 Gy represents the most adopted treatment modality for prostate cancer. Dose escalation in this setting has been demonstrated to improve biochemical control with acceptable toxicity using contemporary radiotherapy techniques. Hypofractionated radiotherapy and stereotactic body radiation therapy have gained an increasing interest in recent years and they have the potential to become the standard of care even if long-term data about their efficacy and safety are not well established. Strong radiobiological basis supports the use of high dose for fraction in prostate cancer, due to the demonstrated exceptionally low values of α / ß . Clinical experiences with hypofractionated and stereotactic radiotherapy (with an adequate biologically equivalent dose) demonstrated good tolerance, a PSA control comparable to conventional fractionation, and the advantage of shorter time period of treatment. This paper reviews the radiobiological findings that have led to the increasing use of hypofractionation in the management of prostate cancer and briefly analyzes the clinical experience in this setting.

Pegylated liposomal doxorubicin (Caelyx®) and oral vinorelbine in first-line metastatic breast cancer patients previously treated with anthracyclines.

Doxorubicin is highly effective and widely used in breast cancer; however, its use is limited by cardiotoxicity related to its cumulative dose. In previous studies, pegylated liposomal doxorubicin (PLD) has shown an acceptable toxicity profile with minimal cardiotoxicity. Between June 2006 and October 2009, 27 metastatic breast cancer patients were treated with first-line PLD and vinorelbine at the University of Florence, Radiotherapy Unit. PLD (30 mg/m²) was administered on day 1, and oral vinorelbine (60 mg/m²) was administered on days 1 and 8 of a 4-week cycle. All patients were previously treated with anthracycline-based adjuvant chemotherapy. Median age was 52 years (range 38-69) and median time to metastasis was 78.5 months. There were no treatment interruptions or discontinuation for cardiac toxicity and no treatment-related deaths. Grade 3 hematological toxicity was observed in 18.6% of patients, and 3.7% had grade 3 non-hematological adverse events. With a median follow-up of 13.2 months (range 3-33), median response duration was 6.1 months, and median PFS was 5.3 months. The overall clinical benefit rate was 55.5%. Our experience adds to evidence supporting the activity and cardiac safety of PLD and vinorelbine in metastatic breast cancer patients previously treated with anthracycline-based adjuvant chemotherapy.
