Abstract
PURPOSE To investigate the influence of carbogen breathing on chemoradiation and the effects of erythropoietin on transfusions. METHODS AND MATERIALS From March 1996 to April 2000, 42 (4 Stage III and 38 Stage IV) patients with head and neck cancer were treated with a twice-a-day hyperfractionated schedule. Each fraction consisted of 5 mg/m(2) of carboplatin plus 115 cGy with carbogen breathing. Treatment was given 5 days per week up to total doses of 350 mg/m(2) of carboplatin plus 8050 cGy in 7 weeks. Anemia was treated either by transfusion or by erythropoietin. RESULTS Forty-one patients tolerated the treatment as scheduled. All patients tolerated the planned radiation dose. Five transfusions were given in the first group, but no transfusion was needed in the erythropoietin group. Local toxicities remained at the level expected with irradiation alone. Chemotherapy toxicity was moderate. Forty-two complete responses were achieved. At two years actuarial local control, cause-specific survival and overall survival are respectively 85%, 69%, and 68%. At four years estimated probabilities of local control, cause-specific survival and overall survival are also 85%, 69%, and 68%. CONCLUSIONS These results compare favorably with those of most reported studies. The addition of carbogen breathing appears to improve the results of chemoradiation alone. Erythropoietin therapy avoided transfusions.

Abstract
BACKGROUND Using chemotherapy as a part of each treatment fraction remains unexplored. This study integrates the concomitant administration of carboplatin with hyperfractionated irradiation by optimizing chemopotentiation through carboplatin administration with each irradiation fraction. METHODS From February 1993 to August 1996, 52 patients with advanced head and neck cancer were treated on a twice-a-day chemoradiotherapy schedule. Each fraction consisted of 115 cGy preceded by 5 mg/m2 of carboplatin. Treatment was given 5 days a week up to total doses of 350 mg/m2 of carboplatin + 8050 cGy in 7 weeks. RESULTS All (100%) of patients tolerated the treatment (83% as scheduled). Acute and late toxicities were moderate. Rates of 96% complete response (CR) and 4% partial response (PR) were achieved. At 52 months, local control and cause-specific survival rates are 72% and 59%, respectively. Nodal control rate is 95%. CONCLUSION These results show potential for improvement upon hyperfractionated radiotherapy alone and compare favorably with those of most reported trials.

Abstract
Actinic prurigo is an inflammatory disease of the skin that appears to be mediated by an abnormal immune response. Cell adhesion molecules play a key role in the induction of the immune response as well as in the pathogenesis of inflammation. We investigated the expression of cell adhesion and activation molecules, as well as the density of Langerhans cells in skin from patients with actinic prurigo. Skin biopsies from ultraviolet light-induced lesions, and non-irradiated areas from 10 actinic prurigo patients were studied; in addition, several spontaneous skin lesions were studied. Skin biopsies from normal individuals were used as controls. The expression of ICAM-1, ICAM-3, LFA-3, CD2, LFA-1, VLA-4, CD1a, VCAM-1, CD69, and activated b1 integrins were assessed by immunostaining. An increased expression of LFA-1, LFA-2, ICAM-3, VLA-4, and activated b1 integrins was observed in the cell infiltrate of actinic prurigo lesions and an up-regulated expression of ICAM-1 was detected in keratinocytes from these specimens. Interestingly, the number of Langerhans cells (CD1a + ) in actinic prurigo skin was not significantly affected by ultraviolet irradiation, a phenomenon that was not observed in normal controls. The increased expression of adhesion molecules in the cell infiltrate of actinic prurigo, indicates that these cells are activated and suggests that they are involved in the skin damage seen in these patients. The resistance of Langerhans cells from patients with actinic prurigo to ultraviolet light may have an important role in the pathogenesis of this condition. The involvement of keratinocytes in the pathogenesis of actinic prurigo is suggested by the expression of ICAM-1 on these cells.

Abstract
We report the case of a 67-year-old woman who was admitted for surgical removal of a Greenfield filter that had been inserted 7 years before because of recurrent deep vein thrombosis associated with pulmonary embolism. This complication appeared on a plain abdominal radiogram that showed a 7 cm distal migration of the filter, a 30-degree angulation, and rupture of a strut at the level of the hub. Computed tomography, aortography, and ascending cavography demonstrated that the inferior vena cava was perforated by the struts and that the ruptured strut had penetrated the infrarenal aorta. As demonstrated by scanning electron microscopy, the fracture was due to a structural defect of the strut at its insertion point within the hub, with no sign of corrosion. Energy-dispersive radiography analysis failed to demonstrate impurity in the metal composition.

Abstract
Pre S1 antigen was measured using an ELISA technique in patients with different forms of hepatitis B virus infection. It was detected in 10 of 19 patients with acute hepatitis B (53%), 12 of 15 chronic hepatitis B virus carriers (80%), 9 of 11 patients with chronic hepatitis B (82%) and 3 of 4 patients with hepatoma and positive markers of hepatitis B virus infection. Pre S1 remained positive beyond 150 days in two patients with acute hepatitis that evolved to chronicity. Among subjects with chronic hepatitis B that received interferon, pre S1 antigen negativized only in the patient that had a complete response. Pre S1 detection is an index of hepatitis B virus replication and its persistence determines chronicity. Its negativization after antiviral therapy should have a predictive value.

Abstract
The Fc-receptor function of the mononuclear phagocyte system (MPS) was examined in 41 children and adult patients, by measuring the clearance of IgG-sensitized, 51Cr-labeled erythrocytes. The Fc-receptor-mediated clearance observed in patients (mean +/- SE) was not significantly different as compared to the control group of similar age distribution. However, the immune clearance time was significantly age-correlated in both groups (acute poststreptococcal glomerulonephritis, APSGN, r = 0.39, p less than 0.05; control r = 0.63, p less than 0.01). The magnitude of the Fc-specific immune clearance and the serum creatinine were also significantly correlated (r = 0.59; p less than 0.01). Circulating immune complexes (as measured by the C1q and conglutinin ELISA) did not correlate with immune clearance, which remained stable in longitudinal studies. Age-related changes in MPS Fc-receptor function could explain, at least in part, prognostic differences between children and adult patients with APSGN.
