Abstract
Background: Sembragiline is a potent, selective, long-acting, and reversible MAO-B inhibitor developed as a potential treatment for Alzheimer’s disease (AD). Objective: To evaluate the safety, tolerability, and efficacy of sembragiline in patients with moderate AD. Methods: In this Phase II study (NCT01677754), 542 patients with moderate dementia (MMSE 13–20) on background acetylcholinesterase inhibitors with/without memantine were randomized (1:1:1) to sembragiline 1 mg, 5 mg, or placebo once daily orally for 52 weeks. Results: No differences between treated groups and placebo in adverse events or in study completion. The primary endpoint, change from baseline in ADAS-Cog11, was not met. At Week 52, the difference between sembragiline and placebo in ADAS-Cog11 change from baseline was – 0.15 (p = 0.865) and 0.90 (p = 0.312) for 1 and 5 mg groups, respectively. Relative to placebo at Week 52 (but not at prior assessment times), the 1 mg and 5 mg sembragiline groups showed differences in ADCS-ADL of 2.64 (p = 0.051) and 1.89 (p = 0.160), respectively. A treatment effect in neuropsychiatric symptoms (as assessed by the difference between sembragiline and placebo on BEHAVE-AD-FW) was also seen at Week 52 only: – 2.80 (p = 0.014; 1 mg) and – 2.64 (p = 0.019; 5 mg), respectively. A post hoc subgroup analysis revealed greater treatment effects on behavior and functioning in patients with more severe baseline behavioral symptoms (above the median). Conclusions: This study showed that sembragiline was well-tolerated in patients with moderate AD. The study missed its primary and secondary endpoints. Post hoc analyses suggested potential effect on neuropsychiatric symptoms and functioning in more behaviorally impaired study population at baseline.

Abstract
Despite the dismal prognosis for patients with squamous cell carcinoma of the head and neck (SCCHN), there have been no novel treatments in over 40 years. Identification of novel tumor antigens in SCCHN will facilitate the identification of potential novel treatment targets. Tumor antigens are proteins selectively expressed by tumor cells and recognized by the host immune system. Phage-displayed tumor antigens were enriched by biopanning with normal and then SCCHN-specific serum. Ninety-six phage clones were sequenced for identification, and 21 clones were validated using Luminex. One of these proteins, L23, a novel tumor antigen in SCCHN, was validated as an oncogene. L23 is upregulated in SCCHN compared with normal keratinocytes. Knockdown of L23 inhibited proliferation, invasion and cell survival. Overexpression of L23 had the reverse effect. Overexpression of L23 in non malignant cells led to transformation. Injection of SCCHN cells with knockdown of L23 in mice, induced tumors that were significantly smaller than control tumors. In conclusion, the immunomic screen yielded a panel of antigens specific to SCCHN; one of these proteins, L23, is a novel oncogene in SCCHN.

Abstract
Rap1GAP is a critical tumor suppressor gene that is downregulated in multiple aggressive cancers, such as head and neck squamous cell carcinoma, melanoma and pancreatic cancer. However, the mechanistic basis of rap1GAP downregulation in cancers is poorly understood. By employing an integrative approach, we demonstrate polycomb-mediated repression of rap1GAP that involves Enhancer of Zeste Homolog 2 (EZH2), a histone methyltransferase in head and neck cancers. We further demonstrate that the loss of miR-101 expression correlates with EZH2 upregulation, and the concomitant downregulation of rap1GAP in head and neck cancers. EZH2 represses rap1GAP by facilitating the trimethylation of histone 3 at lysine 27, a mark of gene repression, and also hypermethylation of rap1GAP promoter. These results provide a conceptual framework involving a microRNA-oncogene-tumor suppressor axis to understand head and neck cancer progression.

Abstract
6001 Background: Chemoradiation (CRT) for HPV (+) SCCOP is associated with a more favorable prognosis than HPV-negative (-) SCCOP. However, the interaction of HPV and T in terms of etiology and disease progression remains unclear. HPV (+) SCCOP pts were prospectively studied to determine if T use was a key variable in discriminating which pts would develop DM, locoregional recurrences (LR), or second primaries (SP). Methods: From 1999–2007, 124 pts with stage III/IV SCCOP were enrolled in one of two CRT trials. Tumor specimens were analyzed for HPV presence and type. Use of T, determined via self-reporting and chart review, was recorded as both continuous (number of pack-yrs) and categorical (never, former, and current) variables. Former T users were subdivided into an early cessation group (quit ≥ 20 yrs prior to diagnosis) and a late cessation group (quit < 20 yrs prior to diagnosis). T use and HPV status were analyzed with respect to survival & the development of DM, LR, or SP. Results: Of the 124 pts, 100 (81%) were HPV (+), 22 of which developed disease progression (22%). Twenty-four were HPV (-), 12 of which had disease progression (50%). Seventeen of 124 pts (14%) developed DM [12 HPV (+), 5 HPV (-)]. Nine of 124 (7%) developed LR [5 HPV (+), 4 HPV (-)], and 8 of 124 (7%) developed SP [5 HPV (+), 3 HPV (-)]. Thirty-two HPV (+) pts were never-T users, 88% (28/32) of which remain alive with no evidence of disease; 3 died from other causes and 1 died of lung metastases from SCCOP. Sixty-eight were HPV (+) and had T exposure. Of 46 former T users, 37/46 (80%) are living. Twenty were HPV (+) and in the early cessation group, 35% (7/20) of which had disease progression [3 LR, 3 DM, 1 SP]. Twenty-six HPV (+) pts were former T users in the late cessation group, 11% (3/26) of which had disease progression [2 DM, 1 SP]. Of 22 HPV (+) current T users, 68% (15/22) are alive and 36% (8/22) have developed disease progression. Seventeen of the 24 HPV (-) pts were current T users, 47% (8/17) of which developed disease progression. Conclusions: Never-T users with HPV-positive SCCOP have improved survival & reduced risk of disease progression compared to HPV (+) & HPV (-) former & current T users. No significant financial relationships to disclose.

Abstract
Morvan's 'fibrillary chorea' or Morvan's syndrome is characterized by neuromyotonia (NMT), pain, hyperhydrosis, weight loss, severe insomnia and hallucinations. We describe a man aged 76 years with NMT, dysautonomia, cardiac arrhythmia, lack of slow-wave sleep and abnormal rapid eye movement sleep. He had raised serum antibodies to voltage-gated K(+) channels (VGKC), oligoclonal bands in his CSF, markedly increased serum norepinephrine, increased serum cortisol and reduced levels and absent circadian rhythms of prolactin and melatonin. The neurohormonal findings and many of the clinical features were very similar to those in fatal familial insomnia, a hereditary prion disease that is associated with thalamic degenerative changes. Strikingly, however, all symptoms in our MFC patient improved with plasma exchange. The patient died unexpectedly 11 months later. At autopsy, there was a pulmonary adenocarcinoma, but brain pathology showed only a microinfarct in the hippocampus and no thalamic changes. The NMT and some of the autonomic features are likely to be directly related to the VGKC antibodies acting in the periphery. The central symptoms might also be due to the direct effects of VGKC antibodies, or perhaps of other autoantibodies still to be defined, on the limbic system with secondary effects on neurohormone levels. Alternatively, changes in secretion of neurohormones in the periphery might contribute to the central disturbance. The relationship between VGKC antibodies, neurohormonal levels, autonomic, limbic and sleep disorders requires further study.

Abstract
Variations in hospitalization rates for selected conditions are being used as indicators of the effectiveness of primary care in small areas. Are these rates actually sensitive to problems in local primary care systems? This study examines the relationship between ambulatory care sensitive condition (ACSC) hospital admission rates and primary care resources and the economic conditions in primary care market areas in North Carolina in 1994. The data show a high degree of correlation between the rates and income but not primary care resources. The distribution of rates did agree with expert assessments of the location of places with poor access to health services. The data confirm that access to effective primary care reflected in lower rates of ACSC admissions is a function of more than the professional resources available in a market area. The solution to reducing disparities in health status may not lie within the health system.

Abstract
OBJECTIVE To describe the patterns of provider use associated with an acute episode of nonspecific low back pain and their impact on cost. METHODS The analysis is based on a prospective cohort study of patients with acute low back pain followed until they recovered completely or to 6 months. Patients were followed after an initial visit to one of four provider types: private primary care physician, chiropractor, orthopedic surgeon, or HMO primary care physician. Follow-up interviews were conducted at baseline, 2, 4, 8, 12, and 24 weeks; 1,580 (97%) of the participants completed the 6-month follow-up. MAIN RESULTS Seventy-nine percent of patients saw only the initial provider who began their care for low back pain. Logistic regression revealed that duration of pain prior to initial visit, sciatica, higher Roland disability score, days to functional recovery, interval to complete recovery, referral by initial provider, disk attribution, satisfaction, and the type of index provider were significantly (p < .05) associated with seeking care from multiple provider types. Age, race, gender, and education were not significant. The adjusted proportions of multiple provider type use were 14% (95% confidence interval [CI] 11%, 17%) for the private primary care provider stratum; 19% (95% CI 16%, 23%) for the chiropractic stratum; 30% (95% CI 23%, 37%) for the orthopedic stratum; and 9% (95% CI 5%, 14%) for the HMO primary care physician stratum. Cost of seeing only the index provider was $439 (95% CI $404, $475), and cost of seeing multiple provider types was $1,137 (95% CI $1,064, $1,211) based on the adjusted model. CONCLUSIONS Use of multiple provider types, is associated with several factors, one of which is the initial provider type. The cost of such use is significant.

Abstract
We recently reported that three members of the integrin family of cell adhesion molecules, designated alpha 2 beta 1, alpha 3 beta 1, and alpha 6 beta 4, are expressed at increased levels within the tumors and cell lines of patients with SCC. These three integrins have been reported to serve as receptors for laminin isoforms, and we also previously observed that laminins are secreted by SCC cell lines isolated from patients. In this study, the expression and localization of the three integrins and laminin in situ was evaluated in ten tumor specimens from patients with SCC by immunohistochemistry using integrin subunit-specific monoclonal antibodies. The ability of the antibodies to inhibit laminin attachment of a human squamous cell carcinoma line was determined by in vitro cell adhesion assay. Laminin and the three integrins were co-localized along the invasive border of the tumor parenchyma in 10/10 patient tumor specimens. Attachment of the UM-SCC-38 cell line to laminin was strongly inhibited by specific mAbs to alpha 2 and alpha 6 integrin subunits alone, or completely using a combination of alpha 2, alpha 3, and alpha 6 subunit specific mAbs. The co-localization of the three abnormally expressed integrins and laminin in patient tumor specimens indicates the potential for interaction of these receptors and ligand in vivo. The results of the cell adhesion assays using a patient SCC cell line that expresses the same repertoire of integrins confirms that SCC attach to laminin isoforms primarily through the alpha 2, alpha 3 and alpha 6 subunit-containing integrins. These findings provide a basis for undertaking experimental studies to obtain small molecule receptor antagonists to determine the role of these integrins in tumor formation, growth, invasion and metastasis in vivo.

Abstract
CaN19, a member of the S100 family of calcium-binding proteins, is known to be "underexpressed" in cultured breast carcinoma-derived cell lines relative to their normal counterparts. By Northern blotting, we confirm these results and find that CaN19 is also markedly "underexpressed" in several carcinoma-derived cell lines of the skin, oral mucosa, and urogenital tract. However, exceptions to the inverse correlation between CaN19 expression and malignancy have been identified, bringing into question the hypothesis that CaN19 functions as a tumor suppressor gene. Unexpectedly, CaN19 mRNA was strongly expressed in bulk specimens of basal and squamous cell carcinomas of the skin and oral cavity. However, in situ hybridization revealed only limited CaN19 expression in tumor cells themselves; the bulk of expression is localized to hyperplastic perilesional epidermis. Tumor cell expression of CaN19 was similar in primary and locally metastatic tumors, indicating that this gene is not necessarily down-regulated during tumor progression. Coordinate overexpression of CaN19 and the "hyperproliferalive" keratin K6a was observed only in tissues undergoing squamous differentiation. Taken together with other recent results from our laboratory, these findings suggest the hypothesis that CaN19 participates in an epidermal growth factor receptor-dependent pathway of regenerative squamous differentiation.

Abstract
In 1994 a 20-year retrospective study was conducted of 297 psychiatric patients admitted to an inpatient rehabilitation program in rural Ireland over a 15-year period (1974 to 1989). All patients were traced. Seventy-six percent had been discharged into the community, and two-thirds required supported housing. Fifty-five percent had experienced acute psychiatric readmissions, and 17 percent became new long-stay patients. The main criticisms of deinstitutionalization did not apply to these patients. No patient became homeless. One patient became involved in possible criminal activity. Four patients committed suicide, and the annual death rate was low-1.8 per 100 patients. The model of care involved was a key factor in the satisfactory outcome.

Abstract
OBJECTIVE To test the feasibility of combining home- and office-based interventions to improve access to health care and health outcomes of Medicaid-eligible mothers and infants. DESIGN Randomized trial in 2 counties in North Carolina (1 rural, 1 urban). Information on health and developmental outcomes was obtained by face-to-face interviews, medical chart abstractions, hospital medical records, and state data tapes. PARTICIPANTS Ninety-three Medicaid-eligible first-time pregnant women in their third trimester and their subsequently born infants, who were followed up until they were 6 months old, and 3 pediatric practices and 1 family practice. INTERVENTIONS Coordinated home visit and office intervention, office intervention, and usual care. Home visits by 3 public health nurses provided parental education and social support and linked families with needed community resources. Women in the office intervention group were encouraged to seek health care for their infants from one of the primary care practices. Participating offices received assistance with Medicaid billing, help developing a system to improve preventive care, and customized patient education materials. RESULTS Mothers reported that the nurses helped them in areas related to the content of the program. An office system for prevention was developed and implemented in all 4 practices for study patients. Families in the intervention groups were more likely than control families to have had a prenatal visit with a pediatrician (P = .01, chi 2), a primary care office as the regular source of sick care (P = .02, chi 2), and less waiting time (P = .02, Student t test). They were also more likely to recall receiving patient education materials (P = .007, chi 2). CONCLUSIONS It is feasible to link clinical and public health approaches to improve the quality and effectiveness of care for socially disadvantaged children. Such interventions should be tested in defined populations.

Abstract
Forty-four consecutive cases of subacute osteomyelitis admitted at our institution over a 12-year period were retrospectively reviewed to assess the effectiveness of conservative versus surgical treatment of this condition and to determine the indications for open biopsy and surgical debridement. Twenty-four cases were treated with antibiotics only, and 20 had surgical debridement followed by antibiotics. Except for one case that received inadequate antibiotic therapy, all patients responded well to this treatment, whether conservative or surgical. At an average follow-up of 18 months, there were no recurrences. Our results also showed that with a careful radiologic assessment of these cases, most lesions showed characteristic benign radiologic features. We can therefore conclude that conservative management of cases of subacute osteomyelitis is as effective as surgical treatment. We believe that conservative treatment with antibiotics should be the first line of management in most of these cases and that open biopsy or surgical debridement or both should be reserved for cases that do not respond to antibiotics or show aggressive radiologic features.

Abstract
OBJECTIVE The purpose of this study was to evaluate the presence and type of mutations of the tumor suppressor gene p53 in squamous carcinoma cell lines of the vulva. STUDY DESIGN Eight low-passage cell lines established from vulvar carcinoma were included in the analysis. Mutational analysis was restricted to exons 5 through 9 of the p53 gene, previously shown to have a high incidence of mutations. The sequences containing exons 5/6,7, and 8/9 were amplified by polymerase chain reaction and screened with a single-strand conformation polymorphism technique on PhastSystem (Pharmacia Biotech, Uppsala, Sweden). Exons from samples showing mobility shifts in single-strand conformation polymorphism were sequenced by polymerase chain reaction direct sequencing. RESULTS Five vulvar carcinoma cell lines showed abnormal electrophoretic mobility of exons 5/6, one of exons 8/9, and one of exon 7. Reduction to homozygosity was detected in four vulvar carcinoma cell lines. Missense mutations were detected by sequence analysis in UM-SCV-2 (codon 171: GAG[Glu]-->TAG[STOP]), UM-SCV-3 (hot spot codon 273: CGT[Arg]-->TGT[Cys]), UM-SCV-4 (codon 151: CCC[Pro]-->CAC[His]), UM-SCV-5 (codon 155: ACC[Thr]-->ATC[lle]), and UM-SCV-7 (codon 245: GGC[Gly]-->AGC[Ser]). UM-SCV-3 also carried a missense mutation with no amino acid change (codon 314: TCC[Ser]-->TCT[Ser]). UM-SCV-7 carried an additional base deletion at codon 249 (AGG-->AG-), likely resulting in a frameshift in transcription and a truncated protein product. Four of the seven mutations were transitions, two were transversions, and one was a deletion. The presence of transitions suggests that at least a proportion of p53 mutations of these cancers may arise spontaneously without exogenous carcinogen exposure. UM-SCV-1A and UM-SCV-1B were derived from the primary tumor and pleural effusion of the same patient. UM-SCV-6 is a cell line that contains human papillomavirus 16. No mutations in these three cell lines were found by single-strand conformation polymorphism. CONCLUSIONS On the basis of previous observations, loss of tumor suppressor p53 function either by mutation or human papillomavirus involvement is a frequent phenomenon in cervical carcinoma cells. It appears now that functional inactivation of p53 is associated also with vulvar carcinoma cell lines, but mutations of the p53 gene are much more common in vulvar than in cervical carcinoma cell lines.

Abstract
A number of reports associate human papillomavirus (HPV) with cervical cancer and cancer cell lines derived from this tumour type. Considerably fewer reports have focused on the role of HPV in carcinomas from other sites of female anogenital squamous epithelia. In this study we have tested for the presence of HPV in eight low-passage vulvar carcinoma cell lines and one extensively passaged cell line, A431. One cell line from a primary vaginal carcinoma was included. The presence of the HPV was evaluated by the polymerase chain reaction (PCR), by Southern blot analysis and by two-dimensional gel electrophoresis. General primer-mediated PCR was applied by using primers from the L1 region, E1 region and HPV 16 E7 region. Southern blot hybridisation was performed under low-stringency conditions (Tm = -35 degrees C) using a whole genomic HPV 6/16/18 probe mixture and under high stringency conditions (Tm = -18 degrees C) with the whole genomic probes of HPV 16 and 33. HPV 16 E6-E7 mRNA was assessed by ribonuclease protection assay (RPA). HPV was found in only one vulvar carcinoma cell line, UM-SCV-6. The identified type, HPV 16, was integrated in the cell genome and could be amplified with all primers used. Also E6-E7 transcripts were found in these cells. Five original tumour biopsies were available from the HPV-negative cell lines for in situ hybridisation. All these were HPV negative with both the HPV 6/16/18 screening probe mixture under low stringency and the HPV 16 probe under high stringency. The results indicate that vulvar carcinoma cell lines contain HPV less frequently than cervical carcinoma cell lines and suggest that a significant proportion of vulvar carcinomas may evolve by an HPV-independent mechanism.

Abstract
A mother brings her 2-year-old child to the office at 4:30 Friday afternoon. The child has been seen only once in the practice for an episode of otitis media. The child missed her follow-up appointment. When the receptionist asks why the child is here, the mother responds that she was able to get a ride today with a neighbor who has an appointment with another physician in the practice. The child is not covered by health insurance. The mother did not bring her immunization record and is not certain what preventive care the child has received in the past.

Abstract
The aim of this study was to investigate the quality of GP referral letters to Specialist Psychiatric Clinics. Ninety one referral letters from 24 GPs were analysed. A schedule based on key items of information previously identified as being of importance to Psychiatrists was used in the analysis. The study revealed that these key items were frequently omitted. In addition, information on social history and medical history was inadequately supplied. Poor letter format and quality of notepaper were also identified. Liaison between GPs and Psychiatrists and Vocational Training Programmes would be helpful in addressing these issues.

Abstract
A 44-year-old woman with proven Acanthamoeba keratitis was successfully treated medically with resultant 6/9 vision. During the treatment, repeated attempts to titrate the patient off topical corticosteroids resulted in recurrent flare-up of inflammatory keratitis from which Acanthamoeba could not be recultured. It is suggested that steroid administration during the course of Acanthamoeba keratitis may need to be withdrawn extremely slowly to avoid the recurrence of what appears to be an immunological corneal reaction.

Abstract
Prepaid, case managed systems have been proposed as a method of controlling costs in Medicaid populations. We investigated the utilization of preventive services in two prepaid Medicaid Competition Demonstration programs in Santa Barbara County, Calif., and Jackson County, Mo. (containing the city of Kansas City). Care in the demonstration sites was compared with care given in similar counties functioning under a traditional fee-for-service Medicaid system--Ventura County, Calif., and St Louis, Mo. We tested the hypothesis that preventive care would be less in the capitated demonstrations. 2735 Children's and 3389 adult's charts were abstracted for care received during the calendar year 1985, after the prepaid demonstration had been in place for more than 1 year. No significant differences were found between the demonstration and comparison counties in the proportion of children with complete DPT or OPV immunizations at 1 year of age, with 56% complete in both California counties and 69 and 65% complete in Jackson County and St Louis, respectively. Regression analysis demonstrated a slight, but statistically significant trend towards more immunizations in the demonstration counties. Pap smear use in women of 15-44 years of age was little different in the California counties, but significantly greater in the Jackson County demonstration in Missouri (64 vs 45%). Physician breast examinations were somewhat more likely to occur in the prepaid, case managed demonstration counties. Capitated, case managed systems for the AFDC Medicaid population appear to result in no diminution of preventive services. Substantial problems exist in this, as in other poor populations, in childhood immunizations.

Abstract
Eleven squamous-cell carcinoma (SCC) cell lines derived from patients with head and neck cancer were tested together with the MCF-7 breast carcinoma cell line for in vitro growth inhibition by tamoxifen. MCF-7 is known to contain cytosolic receptors for estrogen (ER), progesterone (PgR), androgen (AR) and glucocorticoid. We have previously reported the ER, PgR and AR contents of these 11 head-and-neck SCC cancer lines. Starting from day 3 or 4 after passage, cultures were fed daily with medium containing 5% dextran-charcoal-treated fetal bovine serum (D5) and 0, 1, 2.5, 5, 7.5 or 10 microM tamoxifen. Eight of the 11 SCC lines and MCF-7 showed more than 60% growth inhibition when fed with 5 microM tamoxifen. Of these 8 SCC cell lines, 3 contained both ER and PgR, 4 contained only PgR, and one contained neither receptor. The 3 cell lines that were not inhibited by tamoxifen failed to express either ER or PgR. The action of tamoxifen on the cell lines was further investigated by examining the reversibility and the rate of recovery from tamoxifen-induced growth inhibition in the presence or absence of estrogen. MCF-7 and two ER- and PgR-positive SCC cell lines, UM-SCC-12 and UM-SCC-9, recovered more rapidly when the tamoxifen was replaced with medium containing 17-beta estradiol (E2) than when it was replaced with D5 medium alone. However, of the other tamoxifen-inhibited cell lines studied, each recovered equally well whether the tamoxifen was replaced with D5 medium or with D5 medium containing E2. Furthermore, some cell lines spontaneously resumed growth within 4 to 5 days in the presence of tamoxifen if no new tamoxifen was added to the culture dish. This ability is specific for some cell lines, and further study is required to determine its significance.

Abstract
Chromosome studies performed because of the possibility of Turner syndrome in an infant girl with pedal edema and mild neck webbing revealed an XY karyotype. Subsequent exploratory laparotomy showed dysplastic ovaries with nests of germ cells with the morphologic features of gonadoblastoma. Repeat chromosome studies from peripheral blood using high-resolution techniques, and also from skin and ovarian fibroblasts, showed an XY karyotype but with a partial deletion of the Y short arm, which was not detected with standard techniques. These findings indicate that testis determining factors are located in this deleted region of the Y chromosome but that other gene(s) remain that induce gonadoblastoma.
