Abstract
BACKGROUND Surgical treatment options of discoid lateral meniscus in pediatric patients consist of saucerization with or without meniscal repair, meniscocapular stabilization, and, less often, subtotal meniscectomy. PURPOSE To describe a large, prospectively collected multicenter cohort of discoid menisci undergoing surgical intervention, and further investigate corresponding treatment of discoid menisci. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS A multicenter quality improvement registry (16 institutions, 26 surgeons), Sports Cohort Outcomes Registry, was queried. Patient characteristics, discoid type, presence and type of intrasubstance meniscal tear, peripheral rim instability, repair technique, and partial meniscectomy/debridement beyond saucerization were reviewed. Discoid meniscus characteristics were compared between age groups (<14 and >14 years old), based on receiver operating characteristic curve, and discoid morphology (complete and incomplete). RESULTS In total, 274 patients were identified (mean age, 12.4 years; range, 3-18 years), of whom 55.6% had complete discoid. Meniscal repairs were performed in 55.1% of patients. Overall, 48.5% of patients had rim instability and 36.8% had >1 location of peripheral rim instability. Of the patients, 21.5% underwent meniscal debridement beyond saucerization, with 8.4% undergoing a subtotal meniscectomy. Patients <14 years of age were more likely to have a complete discoid meniscus (P < .001), peripheral rim instability (P = .005), and longitudinal tears (P = .015) and require a meniscal repair (P < .001). Patients ≥14 years of age were more likely to have a radial/oblique tear (P = .015) and require additional debridement beyond the physiologic rim (P = .003). Overall, 70% of patients <14 years of age were found to have a complete discoid meniscus necessitating saucerization, and >50% in this young age group required peripheral stabilization/repair. CONCLUSION To preserve physiological "normal" meniscus, a repair may be indicated in >50% of patients <14 years of age but occurred in <50% of those >14 years. Additional resection beyond the physiological rim may be needed in 15% of younger patients and 30% of those aged >14 years.

Abstract
BACKGROUND Grit is the disposition to strive for long-term goals despite setbacks and challenges. Given the lengthy, arduous process of rehabilitation after anterior cruciate ligament reconstruction (ACLR), an athlete's grit may predict postoperative outcomes across time. PURPOSE/HYPOTHESIS The primary aim of the study was to evaluate the relationships between baseline (preoperative) grit and postoperative knee outcomes across the year after ACLR among adolescents. We hypothesized that athletes with more grit would achieve better postoperative outcomes over time than less gritty athletes. STUDY DESIGN Cohort study; Level of evidence, 2. METHODS All participants completed the Short Grit Scale, the Pediatric International Knee Documentation Committee (Pedi-IKDC) Scale, the Lysholm Knee Scoring Scale, the Patient-Reported Outcomes Measurement Information System (PROMIS) pediatric scale for pain interference and mobility, the Hospital for Special Surgery Pediatric Functional Activity Brief Scale (HSS Pedi-FABS), and the Quality of Life in Neurological Disorders (NeuroQoL) Lower Extremity Function Short Form at a preoperative appointment and then again at approximately 3, 6, and 12 months after ACLR. We constructed linear mixed models to assess the relationships between baseline grit, time, age, sex, and postoperative outcome measures (statistical significance of α = .05). RESULTS We included 137 participants (mean age 15.8 ± 2.74 years, 70% female) from a prospective registry of athletes undergoing ACLR by 1 surgeon at a single institution. There were no statistically significant changes in grit over time or differences in grit between age and sex. Higher baseline grit was significantly associated with greater postoperative HSS Pedi-FABS scores (β = 3.72 ± 1.46; P = .01; 95% CI, 0.85-6.59) and NeuroQoL scores across time (β = 3.37 ± 0.93; P < .001; 95% CI, 1.55-5.20). There were no significant associations between baseline grit and Pedi-IKDC, Lysholm, and PROMIS pain interference or mobility scores. CONCLUSION Athletes with higher baseline grit reported superior postoperative physical function and activity level over the course of 1 year after ACLR compared with less gritty athletes. Grit may be a useful measure in predicting success in regaining physical function across time after ACLR in adolescent athletes.

Abstract
BACKGROUND The incidence of meniscus tears and ACL tears in pediatric patients continues to rise, bringing to question the risk factors associated with these injuries. As meniscus tears are commonly repaired in pediatric populations, the epidemiology of repairable meniscus tears is an important for consideration for surgeons evaluating treatment options. PURPOSE To describe meniscal tear patterns in pediatric and adolescent patients who underwent meniscal repair across multiple institutions and surgeons, as well as to evaluate the relationship between age, sex, and body mass index (BMI) and their effect on the prevalence, type, and displacement of repaired pediatric meniscal tears. STUDY DESIGN Case series; Level of evidence, 4. METHODS Data within a prospective multicenter cohort registry for quality improvement, Sport Cohort Outcome Registry (SCORE), were reviewed to describe repaired meniscal tear patterns. All consecutive arthroscopic meniscal repairs from participating surgeons in patients aged <19 years were analyzed. Tear pattern, location, and displacement were evaluated by patient age, sex, and BMI. A subanalysis was also performed to investigate whether meniscal tear patterns differed between those occurring in isolation or those occurring with a concomitant anterior cruciate ligament (ACL) injury. Analysis of variance was used to generate a multivariate analysis of specified variables. Sex, age, and BMI results were compared across the cohort. RESULTS There were 1185 total meniscal repairs evaluated in as many patients, which included 656 (55.4%) male and 529 (44.6%) female patients. Patients underwent surgery at a mean age of 15.3 years (range, 5-19 years), with a mean BMI of 24.9 (range, 12.3-46.42). Of the 1185 patients, 816 (68.9%) had ACL + meniscal repair and 369 (31.1%) had isolated meniscal repair. The male patients underwent more lateral tear repairs than the female patients (54.3% to 40.9%; P < .001) and had a lower incidence of medial tear repair (32.1% vs 41.4%; P < .001). Patients with repaired lateral tears had a mean age of 15.0 years, compared with a mean age of 15.4 years for patients with repaired medial or bilateral tears (P = .001). Higher BMI was associated with "complex" and "radial" tear repairs of the lateral meniscus (P < .001) but was variable with regard to medial tear repairs. CONCLUSION In pediatric and adolescent populations, the data suggest that the surgical team treating knees with potential meniscal injury should be prepared to encounter more complex meniscal tears, commonly indicated in those with higher BMI, while higher rates of lateral meniscal tears were seen in male and younger patients. Future studies should analyze correlates for meniscal repair survival and outcomes in this pediatric cohort undergoing knee surgery.

Abstract
Background: Pivot shift test results have demonstrated widely inconsistent sensitivities when used on awake clinic patients. We believe the painful valgus force applied during traditional pivot shift techniques is the primary culprit and can be circumvented with our novel examination technique. Indications: The reason for publishing this examination technique is to maximize the sensitivity and accuracy of the pivot shift examination in the awake patient. Technique Description: Four major modifications of Ronald Losee’s original valgus-based examination technique are introduced. These are the 4 general modifications: minimizing the sagittal plane arc of motion, avoiding applying valgus force to the knee, application of gentle anteriorly directed force to the lateral tibia, and performing the examination on the patient’s noninjured knee first. We also provide detailed description of the hand placement during the Albright-Losee pivot shift test. (1) Once the patient is relaxed, the examiner’s hands are placed as follows: (1) the ulnar side of the examiner’s thumb is applied to the posterior aspect of the fibular head. The fingers are placed above the patella on the distal femur as shown in the video. (2) With the examiner’s hands in the correct position, the knee is flexed to 20° to 30°. One-to-3 pounds of anterior translatory force is then applied by the side of the thumb to the fibular head while the knee is taken slowly toward extension. Pathological anterior tibial translation can be expected to begin in a 20° to 30° range short of the patient’s complete knee extension. The examiner must be conscious not to provide any valgus or additional internal or external rotation of the leg. Results: This examination is useful for reproducing the subluxation phenomenon in anterior cruciate ligament (ACL)-deficient knees. Our work has shown that these modifications yield an accuracy of 95.51% and a sensitivity of 94.7% in 353 knees examined by 71 clinicians. Discussion/Conclusion: The Albright-Losee pivot shift test is an easy to perform, highly sensitive, and highly specific test. In our recently submitted American Journal of Sports Medicine manuscript, the Albright-Losee pivot shift test suggested to be of greater value than Lachman test. The author(s) attests that consent has been obtained from any patient(s) appearing in this publication. If the individual may be identifiable, the author(s) has included a statement of release or other written form of approval from the patient(s) with this submission for publication.

Abstract
BACKGROUND The discoid lateral meniscus (DLM) is one of the most common congenital anomalies of the knee. The pathomorphology of DLM varies. Current classification systems are inadequate to describe the spectrum of abnormality. PURPOSE A study group of pediatric orthopaedic surgeons from 20 academic North American institutions developed and tested the reliability of a new DLM classification system. STUDY DESIGN Cohort study (diagnosis); Level of evidence, 3. METHODS After reviewing existing classifications, we developed a comprehensive DLM classification system. Four DLM features were evaluated: meniscal width, meniscal height, peripheral stability, and meniscal tear. Stepwise arthroscopic examination using anteromedial and anterolateral viewing portals was established for evaluating these features. Three senior authors who were not observers selected 50 of 119 submitted videos with the best clarity and stepwise examination for reading. Five observers performed assessments using the new classification system to assess interobserver reliability, and a second reading was performed by 3 of the 5 observers to assess intraobserver reliability using the Fleiss κ coefficient (fair, 0.21-0.40; moderate, 0.41-0.60; substantial, 0.61-0.80; excellent, 0.81-1.00). RESULTS Interobserver reliability was substantial for most rating factors: meniscal width, meniscal height, peripheral stability, tear presence, and tear type. Interobserver reliability was moderate for tear location. Intraobserver reliability was substantial for meniscal width and meniscal height and excellent for peripheral stability. Intraobserver agreement was moderate for tear presence, type, and location. CONCLUSION This new arthroscopic DLM classification system demonstrated moderate to substantial agreement in most diagnostic categories analyzed.

Abstract
CONTEXT Many factors can affect the injury risk and quality of life among high school athletes. Early sport specialization and club sport participation may be components to consider when assessing the injury risk and quality of life. OBJECTIVE To investigate patient-reported quality-of-life and injury-history measures among adolescent athletes at different sport-specialization levels and to compare these measures between those who did and those who did not report participating in club sports. DESIGN Cross-sectional study. SETTING High school athletic facility. PATIENTS OR OTHER PARTICIPANTS High school student athletes 13 to 18 years of age were recruited and tested during their annual preseason athletic physical examinations. MAIN OUTCOME MEASURE(S) Our primary grouping variables were sport-specialization level (classified as low, moderate, or high) and club sport participation (organized sport outside of traditional school athletics). Our outcome variables were the Patient-Reported Outcome Measurement Information System Pediatric Profile-37 rating, Severity Measure for Depression-Child score, and injury history. RESULTS A total of 97 individuals participated (mean age = 15.2 ± 1.1 years; 38% female). Relatively similar proportions of individuals reported participating at each level of sport specialization (low = 34%, moderate = 40%, high = 26%). Forty-six (48%) participants stated they participated in club sports. No differences were evident in quality of life (P values = .15-.92 across domains), depression (P = .60), or injury history (P > .70) among the specialization groups. Those who described participating in club sports had a higher proportion of time-loss musculoskeletal injuries (63% versus 29%; P = .002) and of injuries requiring imaging, injection, a cast, a brace, or crutches (72% versus 46%; P = .013) than those who did not. CONCLUSIONS Although no injury-history differences were found among the sport-specialization groups, a higher proportion of club sport athletes than nonclub sport athletes reported a history of injury. Club sports are generally seen as more competitive, and the higher number of injuries seen in this setting could be related to a higher level of play among club sport athletes.

Abstract
BACKGROUND Despite advancements in minimally invasive arthroscopic surgical techniques, post-operative pain management following ACL reconstruction remains a concern. This study compares the effectiveness of two common intraoperative pain management strategies - a femoral nerve catheter (FC) versus a combined femoral nerve catheter and single injection sciatic nerve block (FSB) - in pediatric patients undergoing ACL reconstruction. METHODS The medical records of patients age 8 to 18 who underwent ACL reconstruction at our institution were reviewed retrospectively. All subjects underwent general anesthesia with either FC or FSB. Multivariable linear regression, or modified Poisson regression were used to compare outcome variables across groups. Propensity scores were used to minimize bias due to the non-randomized allocation of the regional anesthesia protocol. RESULTS The study population included 18 subjects in the FC group and 32 subjects in the FSB group. There was no difference in incidence of nausea or opioid prescription refill requests between groups. Total intravenous (IV) morphine equivalent dose, maximum numerical rating scale (NRS) pain score, and percentage of subjects requiring one or more opioid doses in the PACU were significantly greater in the FC group relative to the FSB group. PACU length of stay (LOS) was also significantly greater in the FC group than the FSB group. CONCLUSION This study suggests that FSB may be a more effective pain management technique for reducing the total IV morphine equivalent dose, maximum NRS pain scores, number of PACU postoperative opioid doses, and PACU LOS following ACL reconstruction in the pediatric population.Level of Evidence: III.

Abstract
The central objective in the treatment of any osteochondritis dissecans lesion is to preserve the native articular cartilage and bone. Unfortunately, there are those cases that either fail to heal despite appropriate treatment or present in such a deteriorated state that primary fixation is not possible. This situation is generally determined by the condition of the progeny fragment. Primary fixation may not be the most viable option. In the case of an unsalvageable fragment, the surgeon is faced with several options, which are discussed in this article.

Abstract
BACKGROUND Anal abscesses are commonly associated with fistulas-in-ano and are usually polymicrobial in nature, with gram-negative rods and anaerobes being the most prevalent isolates. Group Milleri Streptococci (GMS) comprise a heterogeneous group of cocci, which are capable of causing severe purulent infection with a high recurrence rate. METHOD All anorectal infections caused by GMS, which were identified at our centre during a 4-year period were retrospectively analysed. The 18 patients with GMS-positive anorectal abscesses were matched with 36 GMS-negative anorectal abscesses to identify outcome characteristics of this clinical entity. RESULTS During the study period, 358 patients underwent surgical treatment for anal infections; GMS were isolated in 46 individuals (13%) including 18 perianal abscesses, 11 pilonidal sinuses, eight fistulae in and nine miscellaneous infections. Seventy-two per cent of perianal GMS infections were polymicrobial with E. coli and Bacteroides fragilis being the predominant second bacteria. Nine patients (20%) developed recurrent abscesses and fistulae-in-ano and underwent additional surgical interventions with resolution at follow-up. Additional antibiotic treatment was administered in 10 patients with complex anal infections. Matched pair analysis revealed that GMS-positive perianal abscesses were more commonly polymicrobial, and that the recurrence rate was higher (55.6% GMS-positive and 22.2% GMS-negative patients, P = 0.017). CONCLUSIONS Our data confirm the propensity of GMS to form deep and recurrent abscesses with a higher recurrence rate than non-GMS infections. First-line treatment includes surgical drainage, and antibiotic treatment may be useful in selected patients.

Abstract
Clostridium difficile (CD) is one of the most common causes of diarrhea in solid organ transplantation (SOT). Between 1996 and 2005, a total of 2474 solid organ transplants were performed at our institution, of which 43 patients developed CD-associated diarrhea. There were 3 lung, 3 heart, 20 liver, 8 kidney-pancreas, 6 kidney, 1 composite tissue, and 2 multivisceral recipients. Onset of CD infection ranged from 5 to 2453 days posttransplant. All patients presented with abdominal pain and watery diarrhea. Toxins A and B were detected using rapid immunoassay or enzyme immunoassay. Treatment consisted of reduction of immunosuppression, fluid and electrolyte replacement, metronidazole (n=20), oral vancomycin (n=20), and a combination of metronidazole and vancomycin (n=2). Toxic megacolon was seen in five patients. Two of them had colonoscopic decompression, and the remaining three required colonic resection. One of these patients died due to multiorgan failure after cured CD enteritis. The remaining patients were discharged with well-functioning grafts and all are currently alive. CD colitis was a rare complication prior to 2000; 38 of the 43 cases occurred thereafter. We conclude that CD colitis represents a severe complication following SOT. Recently, a dramatic increase in the incidence of this complication has been observed. The development of life-threatening toxic megacolon must be considered in solid organ recipients.

Abstract
Identification of a small animal model that undergoes pathological temporomandibular joint (TMJ) degeneration would represent a significant research tool. To date however, no such model has been described. We therefore have investigated the pathological and immunohistochemical features of the TMJ of a transgenic mouse that over expresses the human form of TNFalpha. The TMJ of this animal appears to undergo changes that resemble arthriditics of temporomandibular dysfunction. Furthermore, the disc and articular cells express MMP9 and IL-1. Future work should validate this animal model as one that would have utility for the study of TMJ disorders. Maintenance of connective tissues in joints such as the TMJ is a normal process that allows for the reconstitution of important anatomic features. This maintenance involves both the removal and re-synthesis of structural proteins such as collagens, elastins and proteoglycans. An imbalance in the pathways for degradation and synthesis can lead to the degeneration of joint tissues. We describe the presence of a matrix metalloproteinase, MMP9 (92-kD gelatinase), in TMJ disc and articular cells that likely function in the degradative process. Additionally, we show that this enzyme is under the control of pro-inflammatory cytokines whereby TGFbeta and IL-1 stimulate and PGE(2) inhibits its activity.

Abstract
This two-by-two factorially designed study evaluate approaches for communicating feedback of lung cancer susceptibility to smokers as a method for motivating smoking cessation. The study factors were: method of communicating feedback (by mail with telephone follow-up or in-person) and carbon monoxide feedback (yes or no). One-hundred-forty-four smokers were stratified on race and randomized to one of four conditions. Participants were surveyed at baseline and 2-month follow-up. Polymerase chain reaction (PCR) testing for the absence of the glutathione S transferase mu (GSTM1) gene was the susceptibility marker. Regardless of counseling method or carbon monoxide (CO) feedback, the majority (90%) of smokers accurately recalled the test result and 66% accurately interpreted the meaning of the test result. Smokers who received their result in person were significantly less likely to have read the result booklet than those in the telephone counseling group (OR = .28, 95%; CI .12-.62; p < .05). Neither counseling method nor CO feedback increased smokers' perceived risks for lung cancer. However, at the counseling session those who received in-person counseling were significantly less frightened by the test result than those who received telephone counseling (OR = .42, 95%; CI .20-86; p < .05) and at the 2-month follow-up those who received a CO test were significantly less frightened by their susceptibility result (OR = .40, 95%; CI .17-.92; p < .05) than those who did not have a CO test. Evaluation of further refinements in communicating the meaning of susceptibility results to motivate smoking cessation is warranted.

Abstract
A static deterministic model was used to estimate the effect of the shift to a triple combination therapeutic standard on the annual AIDS Drug Assistance Program (ADAP) budget, total medical care expenditures, and population health outcomes for New York (NY) state ADAP enrollees. The model used opportunistic disease incidence data from the Multicenter AIDS Cohort Study (MACS) and other studies. Costs of treating opportunistic infections (OIs) and other HIV complications with each type of therapy were derived from treatment algorithms and standard unit costs. CD4+ cell counts were used as an index of need for OI prophylaxis and for determining OI incidence. Treatment with zidovudine-based combination therapy has been shown to increase CD4+ cell counts and reduce OI incidence. The model estimated that a change from monotherapy to triple therapy would have increased NY ADAP budget expenditures per enrollee by 115%. However, total medical system costs per ADAP enrollee (including ADAP costs) would decrease by 0.4% in the base case as a result of reduction in OIs and other HIV sequelae and associated costs. Results are sensitive to the assumed percentage of people taking combination therapy as well as to the assumptions made about the impact of the combination therapy on CD4+ cell count. Total ADAP budget impacts will depend on the growth in ADAP enrollment as a result of the availability of more effective therapies. In conclusion, this model demonstrates how access to newer, more effective HIV drug treatments can reduce the costs of treating OIs and provide major health benefits for ADAP enrollees.

Abstract
OBJECTIVE To evaluate the association between smoking and the occurrence of low-grade cervical cytological abnormalities. METHODS We conducted a population-based cross-sectional study of smoking and other exposures in reproductive-age women with normal and abnormal cytology results (Class 1-4 Pap tests). Participants (n = 2,448) were enrollees of the Group Health Cooperative of Puget Sound, a health maintenance organization (HMO) in Washington state, USA. Non-pregnant women were selected monthly from the HMO's cytology database during 1995-6, with over-sampling of women with low-grade abnormalities. All participants completed a structured telephone-administered survey. RESULTS Of the 2,448 participants, 19% (n = 465) had Class 2 Pap results, and 5% (n = 117) had Class 3-4 results. Forty percent of the sample (n = 975) reported ever smoking. Women reporting current/recent smoking (n = 514, 21%) had an increased likelihood of cervical abnormalities (adjusted odds ratio (OR) 1.4, 95% confidence interval (CI 1.1-1.8). Women who had never smoked but who reported recent passive smoking exposure also had a greater likelihood of abnormal test results (OR 1.4, 95% CI 1.0-2.0). Prior smoking was not associated with cytology status. CONCLUSIONS Our results, examining low-grade cervical abnormalities, are compatible with those from studies of more severe cervical lesions, lending added support to the hypothesis that smoking predisposes to development of a spectrum of cervical abnormalities. Thus, even cytologic screening visits represent an opportunity to counsel women smokers about their health risks, particularly the more proximal risks of cervical abnormalities and cancer.

Abstract
OBJECTIVE This study was undertaken to evaluate a smoking cessation intervention provided to women smokers as follow-up to cervical cancer screening. METHODS Women who had had a Pap test in the prior month (N = 4,053) were called to complete a survey that assessed smoking status; 580 identified smokers were randomized to receive Usual care (n = 292) or a Self-help intervention (n = 288) that included a self-help booklet, a smoking and reproductive health information card, and three telephone counseling calls. Women were followed up at 6 and 15 months post-base line. RESULTS Cessation rates in the Usual care (UC) and Self-help (SH) groups did not differ at the 6-month (UC 10.5% vs SH 10.9%, P = 0.56) or 15-month follow-up (UC 15.5% vs SH 10.6%, P = 0.17). Among women with an abnormal Pap test result there were no differences by study group in cessation rates at 6-month (UC 9.8% vs SH 11.0%, P = 0.71) or 15-month follow-up (UC 14.6% vs SH 13.4%, P = 0.96). CONCLUSION Integrating interventions into the clinical setting and involving providers at the point of care may have greater potential for capitalizing on this "teachable moment."

Abstract
PURPOSE Intrastromal injection of mice with antigens from the parasitic helminth that causes river blindness (Onchocerca volvulus) induces eosinophil recruitment to the corneal stroma at the time of maximum corneal opacification and neovascularization. The present study was conducted to examine the role of eosinophils and neutrophils in onchocercal keratitis in control C57Bl/6 mice and in interleukin-5 gene knockout (IL-5(-/-)) mice. METHODS C57Bl/6 and IL-5(-/-) mice were immunized subcutaneously and injected intrastromally with soluble O. volvulus antigens. Mice were killed at various times thereafter. Development of keratitis was assessed by slit lamp examination, and inflammatory cells in the cornea were identified by immunohistochemistry. RESULTS A biphasic recruitment of inflammatory cells was observed in C57Bl/6 mice; neutrophils predominated during the first 72 hours after intrastromal injection and subsequently declined, whereas eosinophil recruitment increased as time elapsed and comprised the majority (90%) of cells in the cornea by day 7. In contrast, neutrophils were the predominant inflammatory cells in IL-5(-/-) mice at early and late time points and were associated with extensive stromal damage and corneal opacification and neovascularization. Eosinophils were not detected in these mice at any time. CONCLUSIONS In the absence of eosinophils, neutrophils can mediate keratitis induced by helminth antigens. Together with the early neutrophilic infiltrate in control animals, these observations indicate that neutrophils have an important role in onchocercal keratitis.

Abstract
OBJECTIVE To determine whether 1) women smokers are aware that smoking increases their risk for cervical cancer; 2) awareness of risk factors and its impact on motivation to quit smoking vary by age; and 3) providers are advising smokers to quit smoking during routine gynecologic visits. METHODS Women aged 18 years and older who had a Papanicolaou test in the prior month were identified from a managed care cytology database. Four weeks after receiving their test result, women were called to complete a health behavior survey in which their smoking status, sexual history, knowledge of risk factors for cervical cancer, and motivation to quit smoking were assessed. RESULTS Only 49% of the 613 smokers surveyed were aware that smoking increased their risk of cervical cancer. Women aged 34 years and younger were significantly more likely to agree that smoking increased their risk for cervical cancer than women aged 45 years or older (54% versus 40%). Concern that smoking might cause cervical cancer or other cancers was endorsed highly by women as a motivator for cessation, particularly for women smokers aged 18-26 (mean 8.1 and 7.6 on 10-point scales, respectively). About 50% of the women reported that their provider had asked about smoking and had encouraged cessation. Only about 30% of smokers were aware of well-established risk factors for cervical cancer such as the number of lifetime sexual partners and not using a condom. CONCLUSION Routine gynecologic screening visits represent an important and underutilized clinical opportunity to intervene with young women smokers.

The ultimate fate of the expanded pool of osteoblasts formed following a typical bone injury is unclear. Since necrosis has not been described in the latter stages of bone healing, there must be some other mechanism by which obsolete osteoblasts are cleared from an injury site. We therefore evaluated the possibility that their removal is pre-programmed, by investigating the occurrence of apoptosis in rats that received a standardized bone injury. Histological evidence identical to that found in tissues known to exhibit apoptosis was obtained, thereby showing that programmed cell death was a normal concomitant of fracture healing. The concentration of apoptotic bodies reached its maximum after the differentiative response had peaked, suggesting that the two processes were coordinated. The same result was found in a second group of rats that received the same bone injury plus a simultaneous standardized soft-tissue injury. The combined injuries resulted in more osteoblasts and more apoptotic bodies, but an identical temporal relationship between the peak responses in the two parameters. The results suggested that osteoblasts were removed from the injury site via apoptosis, and that the process was coordinately regulated with differentiation. Since the number of apoptotic bodies per osteoblast varied during healing, it is likely that apoptosis was associated with healing and not merely with osteoblast concentration.

Abstract
Corneal inflammation (keratitis) is a major cause of visual impairment in Onchocerca volvulus infection. Previous studies showed that onchocercal keratitis can be induced in mice following s.c. immunization and intracorneal injection with soluble O. volvulus Ags (OvAg), and that the inflammatory response is dependent on T cells and IL-4. Since recombinant IL-12 impairs IL-4-dependent, Th2-mediated responses in other parasitic infections and in models of allergic asthma, the present study was undertaken to determine the effect of IL-12 on onchocercal keratitis. Mice were injected i.p. with IL-12 or saline at the time of initial sensitization to OvAg. Surprisingly, IL-12 treatment caused significant exacerbation of corneal pathology, which was associated with increased eosinophil and mononuclear cell infiltration into the corneal stroma. Consistent with the well-documented effect of IL-12 on Th1 cell development, corneas of IL-12-treated animals had elevated expression of the Th1 cytokine IFN-gamma and diminished expression of the Th2 cytokines IL-4, IL-5, IL-10, and IL-13. However, corneas from these animals also had marked elevation of alpha- and beta-chemokines known to be active on eosinophils and mononuclear cells, including IFN-gamma-inducible protein (IP)-10, macrophage inflammatory protein-1alpha, macrophage inflammatory protein-1beta, JE/monocyte chemotactic protein-1, RANTES (regulated upon activation, normal T expressed and secreted), and eotaxin. Together, these data indicate that IL-12 exacerbates OvAg-mediated corneal pathology by enhancing chemokine expression and recruitment of inflammatory cells.

Abstract
Corneal inflammation similar to human onchocercal keratitis can be induced in mice by subcutaneous immunization of a soluble extract of Onchocerca volvulus (OvAg) followed by direct injection of OvAg into the corneal stroma. Previous studies have shown that corneal pathology is associated with increased systemic and corneal Th2 cytokine expression and that IL-4 gene knockout (IL-4-/-) mice develop less severe or no O. volvulus-mediated keratitis. The current study examined the contribution of Th2 cytokines to the diminished OvAg-induced corneal immunopathology observed in IL-4-/- mice. IL-4-/- mice (129Sv x C57B1/6), wild-type F2 littermates (IL-4+/+), and C57B1/6 mice were sensitized by repeated subcutaneous immunization with OvAg. Ten days after the final immunization, mice were sacrificed, spleens were removed, and cells were incubated with OvAg. Cells from immunocompetent C57B1/6 and IL-4+/+ mice produced IL-4 and IL-5, but no IFN-gamma, whereas cells from IL-4-/- mice had elevated IFN-gamma and no IL-4. Interestingly, cells from these animals produced levels of IL-5 protein equivalent to those of C57B1/6 and IL-4+/+ mice. To determine cytokine production in corneas during the onset of onchocercal keratitis, OvAg-immunized mice were injected intracorneally with OvAg, and cytokine gene expression in the cornea was determined by RT-PCR. Temporal analysis of cytokine gene expression in corneas of immunocompetent mice showed that the Th2-associated cytokines IL-4, IL-5, IL-10, and IL-13 were produced within 1 day of intrastromal injection, with sustained elevations for 10 days. Maximal IFN-gamma mRNA levels were not detected until Day 10. This was in contrast to IL-4-/- mice in which IFN-gamma appeared at Day 1 and remained elevated for at least 10 days. Moreover, in corneas from IL-4-/- mice, all Th2 cytokines with the exception of IL-4 were up-regulated and expressed with kinetics similar to that of IL-4+/+ littermates. Histologically, corneas from IL-4-/- mice were less edematous and contained fewer eosinophils and other inflammatory cells than those from immunocompetent controls. As there was no difference in peripheral eosinophil levels, these data indicate that the diminished severity of onchocercal keratitis in IL-4-/- mice is not due to failure to develop systemic or local Th2 cytokine responses or to produce eosinophils, but that IL-4 may be involved in recruitment of eosinophils and other inflammatory cells into the corneal stroma.

Abstract
OBJECTIVE To assess whether the dietary intake of long-chain n-3 polyunsaturated fatty acids from seafood, assessed both directly and indirectly through a biomarker, is associated with a reduced risk of primary cardiac arrest. DESIGN Population-based case-control study. SETTING Seattle and suburban King County, Washington. PARTICIPANTS A total of 334 case patients with primary cardiac arrest, aged 25 to 74 years, attended by paramedics during 1988 to 1994 and 493 population-based control cases and controls, matched for age and sex, randomly identified from the community. All cases and controls were free of prior clinical heart disease, major comorbidity, and use of fish oil supplements. MEASURES OF EXPOSURE: Spouses of case patients and control subjects were interviewed to quantify dietary n-3 polyunsaturated fatty acid intake from seafood during the prior month and other clinical characteristics. Blood specimens from 82 cases (collected in the field) and 108 controls were analyzed to determine red blood cell membrane fatty acid composition, a biomarker of dietary n-3 polyunsaturated fatty acid intake. RESULTS Compared with no dietary intake of eicosapentaenoic acid (C20:5n-3) and docosahexaenoic acid (C22:6n-3), an intake of 5.5 g of n-3 fatty acids per month (the mean of the third quartile and the equivalent of one fatty fish meal per week) was associated with a 50% reduction in the risk of primary cardiac arrest (odds ratio [OR], 0.5; 95% confidence interval [CI], 0.4 to 0.8), after adjustment for potential confounding factors. Compared with a red blood cell membrane n-3 polyunsaturated fatty acid level of 3.3% of total fatty acids (the mean of the lowest quartile), a red blood cell n-3 polyunsaturated fatty acid level of 5.0% of total fatty acids (the mean of the third quartile) was associated with a 70% reduction in the risk of primary cardiac arrest (OR, 0.3; 95% CI, 0.2 to 0.6). CONCLUSION Dietary intake of n-3 polyunsaturated fatty acids from seafood is associated with a reduced risk of primary cardiac arrest.

Abstract
The human papillomavirus (HPV) has been shown to be associated with neoplasms of the human colon using immunohistochemistry and in situ hybridization. We now report our use of the polymerase chain reaction and Southern blotting to investigate that same association. We selected 38 carcinomas, 21 adenomas, and 24 normal mucosal samples for the current study. Tissue sections were prepared, and then DNA was extracted and subjected to 40 cycles of amplification using Thermus aquaticus DNA polymerase and a set of degenerate primers. Amplified products were analyzed by agarose gel electrophoresis and Southern blotting. The L1 region of the HPV genome was identified in 13 of 38 carcinomas (32%), 8 of 21 adenomas (38%), and 2 of 24 normal biopsy specimens (8%). These observations validate our previous results and confirm the presence of HPV in human colon mucosa and tumors of that mucosa.

Abstract
The validity and reliability issues involved in using alternative patient classification systems were reviewed. Disease Staging and Patient Management Categories (PMCs) were applied separately and in conjunction with DRGs to three populations of patients drawn from a nine-hospital community data base. Data were examined with analyses that were as consistent as possible with hospital-based reviews of resource utilization. Questions focused on content and context validity (partially assessable by homogeneity), general and statistical reliability (measured by variance reduction), gaming, and cost. Ordinal stratifications were inconsistently produced, and improvement to DRGs' homogeneity was generally negligible. When used alone, staging produced only half the variance reduction of DRGs. PMCs, when used alone, appeared to produce sizeable variance reductions that may have been due to the large number of one- and two-case categories produced. Staging had category overlap, was expensive, and was unidimensional and subject to manipulation. PMCs had potentially serious logic problems, and both were inadequately documented. Neither system was considered appropriate for all needs, but each might work adequately under well-defined and limited conditions.

Abstract
A stable model has been developed for oral mucosal anaplastic epidermoid carcinoma. This model more closely resembles the biologic characteristics of human oral carcinoma than previous models, such as primary epidermoid carcinomas induced in hamster buccal pouches or tongue by chemical carcinogens. This anaplastic oral cancer model was developed by serial abdominal transplantation in neonatal hamsters of original DMBA-induced primary epidermoid carcinomas of hamster buccal pouch. After the second generation, the tumors became stable, maintained an anaplastic appearance histologically, and were biologically aggressive, with rapid growth and metastatic potential. The original DMBA-induced buccal pouch tumors from 42 adult hamsters were transplanted abdominally through five generations in 151 neonatal hamsters. Immunosuppression was crucial in the initial transplantation but became unnecessary in the later serial transplantations. This model can serve as the basis for a variety of future immunologic and biologic studies dealing with oral cancer.

Abstract
An anaplastic model of oral cancer has been developed by abdominal transplantation of carcinomas induced in buccal pouches of hamsters by DMBA. The transplanted tumors were replanted abdominally through five generations. The original carcinomas of the buccal pouch became stable in the abdomen after two generations of such transplantations and could thereafter be retransplanted intraperitoneally with 100% of success, as well as being transferable again to the buccal pouches of hamsters, where they were capable of being maintained as an oral model for anaplastic epidermoid carcinoma.

Abstract
Epidermoid carcinomas of oral mucosa were induced with DMBA in the buccal pouches of hamsters. The well-differentiated primary tumors were allografted into the peritoneal cavities of neonatal hamsters that had been treated with antilymphocyte serum. Solid tumors grew rapidly in the peritoneum and were harvested 6 to 31 days postimplantation. Gross and histopathologic specimens revealed infiltrative masses of tumor that had become more anaplastic than the original tumor. This in vivo model has considerable potential as a means of studying the immunology of oral cancers during tumor progression.

Abstract
Chromosome 8 is the largest autosome thus far found to be trisomic among liveborn infants. Trisomy 8 "mosaicism" syndrome (T8mS) consists primarily of individuals whose chromosome complement is mosaic for chromosome 8 (T8m), i.e., patients with a chromosomally normal cell line in addition to the trisomic 8 cell line, and a few known individuals with full trisomy 8 (T8), i.e., each cell observed contains an extra chromosome 8. Reported cases of both types share a number of common features and thus have helped to delineate a new syndrome. Common features of T8mS include mild-to-moderate mental retardation, strabismus, osseous and soft tissue abnormalities, lowset and/or malformed ears, broad bulbous nose, palate deformity, various types of congenital cardiovascular disorders, hydronephrosis, cryptorchidism, and characteristic dermatoglyphics. Since chromosomal mosaicism is often present in this syndrome it is not surprising that considerable phenotypic variation exists. The present report of one of the youngest individuals yet described with T8m adds two more physical findings (dense corneal clouding and a heretofore undescribed clavicular deformity) to the constellation of abnormalities associated with T8mS. On the basis of the phenotypic and cytogenetic findings in this and 17 similar patients previously reported it is proposed that T8mS is a distinct clinical entity.
