    Notes: A detailed study of current transport at the Schottky-type n-InP | poly(pyrrole) interface is presented. At room temperature, this interface exhibits an average quality factor of n=1.02±0.02, a C–V barrier height of qφbCV=0.78±0.01 eV, and a surface recombination velocity over two orders-of-magnitude slower than at ideal n-InP metal interfaces. These latter two parameters imply an effective barrier height of 0.9 eV, which is among the highest values ever reported for an n-InP Schottky-type diode. The quality factor increases monotonically with decreasing temperature reaching a value of 1.23 at 98 K. Substantial curvature is also observed in a Richardson plot at reduced temperature. These temperature dependencies can be quantitatively modeled using thermionic emission theory in the presence of barrier inhomogeneities. Standard models, including thermionic emission with image force effects, interfacial layer models with and without surface states, and tunneling, do not adequately explain the temperature dependence of the quality factor and the curvature in the Richardson plot. © 1999 American Institute of Physics.

    Notes: The interface between the inorganic semiconductor p-type InP and the conjugated polymer poly(pyrrole) exhibits the electrical characteristics of a Schottky diode. Capacitance–voltage measurements yield an average barrier height of 0.62 ± 0.01 eV at temperature T =298 K. At the same temperature, the empirical quality factor, extracted from current–voltage measurements, is near unity. However, the current–voltage measurements show a deviation from thermionic emission theory as the temperature is reduced, as witnessed by the increase of the quality factor and the curvature in the Richardson plot. Such deviation is best explained by the barrier inhomogeneity model, in which the barrier becomes voltage dependent due to the interaction of a small low-barrier region with a higher surrounding potential, termed the "pinch-off" effect. Traditional current–voltage models, including image force lowering or an interfacial layer, cannot predict the temperature dependence of the current–voltage data, although thermionic field emission may facilitate current transport in the interfaces with a higher doped InP substrate. Furthermore, the probability of sufficiently energetic incident charge carriers crossing the interface, termed the transmission coefficient, is smaller than that observed in metal Schottky diodes.© 2001 American Institute of Physics.

    Notes: In response to interest by dental students and patient needs, an elective program in implant dentistry was started at the University of Detroit Mercy School of Dentistry (UDM) in the summer of 1994. The 1-year program is offered to a group of 10 senior students out of a class of 72. Implant treatment is provided to selected edentulous and partially edentulous patients. Predoctoral students participate in diagnosis and treatment planning, assist in surgical placement, and perform the prosthodontic procedures. A survey was sent to 160 UDM graduates, and 90 responded. Out of the 90 respondents, 35% had participated in the elective implant program and 65% had not. A Pearson correlation matrix was used to analyze their responses. A stronger positive correlation with offering and restoring implants was seen in graduates who had completed the elective program in implant dentistry.

    Notes: Abstract: A retrospective analysis of the treatment of locally advanced breast cancer (LABC) was undertaken at Stanford Medical Center to assess the outcome of patients who did not undergo surgical removal of their tumors. Between 1981 and 1998, 64 patients with locally advanced breast cancer were treated with induction chemotherapy, radiation with or without breast surgery, and additional chemotherapy. Sixty-two (97%) patients received cyclophosphamide, doxorubicin, and 5-fluorouracil (CAF) induction chemotherapy. Induction chemotherapy was followed by local radiotherapy in 59 (92%) patients. Based on the clinical response to chemotherapy and patient preference, 44 (69%) patients received no local breast surgery. Radiotherapy was followed by an additional, non-doxorubicin-containing chemotherapy in all patients. The mean age of patients was 49 years. Of the 65 locally advanced breast cancers in 64 patients, 26 (41%) were stage IIIA, 35 (55%) were stage IIIB, and 4 (6%) were stage IV (supraclavicular lymph nodes only). Response to induction chemotherapy was seen in 59 patients (92%), with 29 (45%) achieving a complete clinical response and 30 (47%) a partial clinical response. With a mean follow-up of 51 months (range 7–187 months), 43 patients (67.2%) have no evidence of recurrent disease. Eight (12.5%) have recurred locally, and 21 (32.8%) have recurred with distant metastasis. Actuarial 5-year survival is 75%, disease-free survival is 58%, and local control rate is 87.5%. These data indicate that the routine inclusion of breast surgery in a combined modality treatment program for LABC does not appear necessary for the majority of patients who experience a response to induction chemotherapy.

    Notes: Abstract: Lobular carcinoma in situ (LCIS) has gone from a rare form of mammary cancer to a marker of increased risk. Treatment options have undergone a corresponding change from ipsilateral mastectomy with axillary node dissection to observation once it became clear that the majority of patients did not progress to invasive cancer. However, recent events suggest a re-evaluation of LCIS management options. It is clear that even meticulous observation may fail to detect invasive cancer before systemic spread has taken place. This fact plus the identification of breast cancer genes have brought a renewed interest in prophylactic mastectomy. At the same time pathologists feel that it is possible to identify microscopic features of LCIS pointing to an increased likelihood of developing invasive cancer. As a result physicians are being asked to better quantitate risks for individual patients. Most patients with LCIS do not need bilateral mastectomies, but we are coming closer to identifying the minority that would be better served by prophylactic surgery.
