    Laparoscopically Resected Foregut Cyst Adjacent to the Right Adrenal Gland

    A case of 49-year-old woman with a retroperitoneal undifferentiated foregut cyst attached to the right adrenal gland is reported. The bronchogenic cyst is a type of foregut cyst with a cartilage component, but in this case the multicystic tumor lacked both cartilage and gland. It is quite rare among retroperitoneal tumors and has not been reported so far to have malignant potential. The preoperative diagnosis was an adrenal benign incidentaloma, and the patient successfully underwent laparoscopic resection of the cystic tumor together with the right adrenal gland by lateral transabdominal approach. Laparoscopic surgery for a retroperitoneal tumor is problematic, however, since benignancy cannot be predicted. In laparoscopic adrenalectomy for non-functioning adrenal tumor, therefore, a differential diagnosis from retroperitoneal tumor should be given serious consideration

    Low temperature method for the production of calcium phosphate fillers

    BACKGROUND: Calcium phosphate manufactured samples, prepared with hydroxyapatite, are used as either spacers or fillers in orthopedic surgery, but these implants have never been used under conditions of mechanical stress. Similar conditions also apply with cements. Many authors have postulated that cements are a useful substitute material when implanted in vivo. The aim of this research is to develop a low cristalline material similar to bone in porosity and cristallinity. METHODS: Commercial hydroxyapatite (HAp) and monetite (M) powders are mixed with water and compacted to produce cylindrical samples. The material is processed at a temperature of 37–120 degrees C in saturated steam to obtain samples that are osteoconductive. The samples are studied by X-ray powder diffraction (XRD), Vickers hardness test (HV), scanning electron microscopy (SEM), and porosity evaluation. RESULTS: The X-ray diffractions of powders from the samples show patterns typical of HAp and M powders. After thermal treatment, no new crystal phase is formed and no increase of the relative intensity of the peaks is obtained. Vicker hardness data do not show any relationship with treatment temperature. The total porosity decreases by 50–60% according to the specific thermal treatment. Scanning electron microscopy of the surfaces of the samples with either HAp 80%-M 20% (c) or Hap 50%-M 50% (f), show cohesion of the powder grains. CONCLUSIONS: The dissolution-reprecipitation process is more intesive in manufactured samples (c) and (f), according to Vickers hardness data. The process occurs in a steam saturated environment between 37 degrees and 120 degrees C. (c) (f) manufactured samples show pore dimension distributions useful to cellular repopulation in living tissues
