Abstract
OBJECTIVE To examine the relationship between physical abuse of adolescents and parenting by mothers and fathers and whether the association differs by gender. METHODS Subjects were adolescents, 51 girls and 45 boys, documented by Child Protective Services (CPS) as physically abused during adolescence. Comparison subjects were non-abused adolescents, 47 girls and 48 boys, from the same suburban communities. Subjects completed the following: Family Adaptability and Cohesion Evaluation Scale, Parental Bonding Instrument, modified Conflict Tactics Scale (assessing physical abuse/punishment by each parent). RESULTS Although CPS generally cited fathers as the abuse perpetrators, abused boys and girls often reported experiencing physical maltreatment from both parents. Not surprisingly, comparison subjects rated parents more positively than abused subjects. For both groups, mothers were perceived as more caring and less controlling, were reported to have closer relationships with their adolescents, and were less likely to use abuse/harsh punishment than were fathers. Differences between the adolescents' perceptions of mothers and fathers were more pronounced for abused than for comparison subjects. Boys' and girls' perceptions of parenting were generally similar except that girls, especially the abused girls, reported feeling less close to fathers. Abused girls also viewed mothers as less caring than the other groups viewed mothers. Abused girls were also less likely than abused boys to perceive that either parent, but particularly fathers, had provided them with an optimum style of parenting. CONCLUSIONS Adolescents who experienced relatively mild physical abuse reported dysfunctional family relationships, which may place them at risk of poor adult outcomes. Adolescents' reports suggest that CPS reports may underestimate physical maltreatment by mothers.

Abstract
BACKGROUND AND PURPOSE Pleomorphic adenoma is the most common parotid neoplasm. It has a relatively high rate of recurrence after surgery. Imaging features of recurrent parotid pleomorphic adenoma have been infrequently reported in the radiology literature. In the present study, we reviewed our institutional experience with imaging of recurrent parotid pleomorphic adenomas. MATERIALS AND METHODS Retrospective imaging and chart review of 24 patients (9 men, 15 women; age, 29-63 years) with recurrent pleomorphic adenoma of the parotid were performed. Images were reviewed as to the margins, site, multiplicity, signal intensity, and enhancement pattern of the recurrent lesions by 2 neuroradiologists. RESULTS We found a high incidence of multiple lesions in the operative bed, most of which were extremely bright on T2-weighted images; some of the lesions demonstrated a cystic appearance with peripheral enhancement. We also noted tiny lesions in the subcutaneous fat and in regions distant from the immediate operative bed. CONCLUSION Although recurrent disease is usually clinically apparent, sometimes prior surgical history is lacking or recurrence may be detected on routine surveillance imaging after initial surgery. The presence of solitary or multiple subcutaneous T2 hyperintense lesions in the operative bed, subcutaneous fat, and/or spaces adjacent to the parotid in patients with prior parotidectomy for pleomorphic adenoma is consistent with the diagnosis of neoplastic recurrence. The radiologist should maintain a high index of suspicion for recurrent pleomorphic adenoma with this characteristic imaging appearance.

Abstract
Granulocyte colony-stimulating factor (G-CSF) is widely used following myeloablative chemotherapy (high-dose therapy; HDT) and peripheral blood progenitor cell rescue (PBPCR) to reduce neutrophil engraftment time. The dose and duration required to gain maximum clinical and economic benefit has not been fully investigated. This double blind placebo-controlled randomised trial was performed to determine whether short course low-dose or standard-dose Lenograstim (L) would influence recovery of haematopoiesis following HDT and PBPCR. Sixty-one patients were randomised between May 1999 and November 2004, to receive standard-dose lenograstim (263 microg/d), low-dose lenograstim (105 microg/d) or placebo injections. These commenced on day +5 following PBPCR and continued until neutrophil engraftment [absolute neutrophil count (ANC)] > or = 0.5 x 10(9)/l. Patients received standard supportive care until haemopoietic recovery. Both standard- and low-dose lenograstim resulted in a significantly shorter median time to neutrophil recovery (ANC > or = 0.1 x 10(9)/l:10.0 vs. 11.0 d, P = 0.025; ANC > or = 0.5 x 10(9)/l:11.0 vs. 14.0 d, P = 0.0002) compared with placebo. There was no significant difference in blood product support, antibiotic usage, documented infection, overall survival or relapse-free survival between the groups. Short course low-dose lenograstim is as effective as standard-dose in reducing neutrophil engraftment time following HDT and PBPCR.

Abstract
BACKGROUND In a primary rhinoplasty that requires a humpectomy, the dorsal aspect of the upper lateral cartilages is commonly discarded. Many of these patients need spreader grafts to reconstruct the middle third of the nose. However, it is possible to reconstruct the upper lateral cartilages into "spreader flaps" that act much like spreader grafts. METHODS A tunnel is created on the underside of the upper lateral cartilage, which is released from the cartilaginous septum and also from its attachment to the nasal bone (medially). It is then rolled on itself to make a spreader flap, which is secured with sutures. Scoring along the dorsal edge of the upper lateral cartilage may be necessary. The flap is then secured to the dorsal edge of the reduced dorsal septum. RESULTS In 21 patients who underwent an open approach (and four patients who underwent the closed approach), the spreader flap almost always reconstructed the middle third of the nose. It was easy to execute in the open approach but difficult in the closed approach. At surgery, two patients undergoing the open approach and one patient undergoing the closed approach needed spreader grafts because the flaps were too narrow. Postoperatively, only one patient (operated on by the open approach) exhibited inadequate nasal width. CONCLUSIONS Spreader grafts are the standard for reconstructing the middle third of the nose. However, the spreader flap avoids harvesting and carving cartilage for those grafts. In the open approach, the technique is easy to execute. Conclusions could not be drawn regarding the long-term success with the closed approach.

Abstract
INTRODUCTION The relationship between the source of sexual information and adolescent sexual behavior is not well understood. MATERIALS AND METHODS As part of a larger study, 892 sexually active female adolescents between 15 and 18 years of age completed a paper-and-pencil survey which assessed discussions about sexual intercourse, contraceptive use and condom use among friends and family members and their own sexual behavior. Multivariate logistic regression analyses were performed to examine associations while controlling for key demographics. RESULTS Adolescents who had never used condoms were less likely to report having had discussions about sexual intercourse with their friends [adjusted odds ratio (AOR) = 0.2]. Discussions about condom use among friends and family members were associated with condom use in the past 3 months, with adolescents who used condoms at least half of the time being more likely to report hearing discussions relative to adolescents who never used condoms (AORs 2.0-3.8). Furthermore, the number of sexual partners was related to whether the adolescent had heard discussions among her family about condom use; the higher the number of sexual partners, the more likely the adolescent was to have heard discussions. For adolescents reporting 2-3, 4-5 and 6 or more partners (relative to one partner), the AORs were 1.7, 2.3 and 2.7, respectively. DISCUSSION Adolescents exposed to information about condom use among the primary individuals in their lives are more likely to be engaging in this behavior themselves.

Abstract
Influenza C virus contains a single surface glycoprotein in its lipid envelope which is the hemagglutinin-esterase-fusion glycoprotein (HEF). HEF binds cell-surface receptors, is a receptor-destroying enzyme (a 9-O-acetylesterase), and mediates the fusion of virus and host cell membranes. A bromelain-released soluble form of HEF has been crystallized. Two different tetragonal forms have been identified from crystals with the same morphology [P(1(3))22, a = b = 154.5, c = 414.4 A, and P4(1(3))2(1)2, a = b = 217.4, c = 421.4 A]. Both crystal forms share a common packing scheme. Synchrotron data collection and flash cooling of crystals have been used for high-resolution data collection.

Abstract
AIMS To evaluate the effect of the implementation of an asthma clinical pathway on asthma in children in general practice. METHODS A randomized, controlled trial involving 270 general practitioners. One group of general practitioners implemented the asthma clinical pathway for children (intervention group) and the control group continued with their usual asthma medical care management. The main outcome measures were admissions to hospital for asthma and attendance at the Children's Emergency Department. Compliance with the guidelines was assessed by examining asthma drug prescriptions. RESULTS Admissions to hospital for asthma dropped 40% in the intervention group, by 33% in the control group and by 22% in general practitioners not participating in the trial. The differences between the intervention and control and between the intervention and non-participating general practitioners were not statistically significant. The decrease in attendance at the Children's Emergency Department decreased by 25%, 30% and 19%, respectively, but this was not statistically significant. There was a significant decrease in prescriptions for oral relievers, dry powder relievers in the under 6s, mast cell stabilizers and methylxanthines in both control and intervention groups. However, only for oral relievers was there a significant difference between the intervention group and control, with the decrease larger in the intervention group (p < 0.001). CONCLUSIONS Admissions to hospital for asthma decreased, as did attendance at the Children's Emergency Department. Prescriptions for asthma medication changed in the direction anticipated with compliance with the asthma clinical pathway. However, we found no evidence within the study that implementation of the asthma clinical pathway by general practitioners resulted in lower morbidity than those general practitioners who did not implement the pathway. Possible explanations are that these general practitioners were already providing care according to the recommendations of the pathway, or that there was contamination of the control group by the intervention, or that the guidelines, although based on currently accepted recommendations, are ineffective.

Abstract
Preterm labour is the major cause of perinatal morbidity and mortality in humans. The incidence is around 10% and the causes are often unknown. Consumption of dietary n-6 polyunsaturated fatty acids (PUFAs) in western societies is increasing. These are metabolized to arachidonic acid, the precursor for 2-series prostaglandins (PGs), major signalling molecules during labour. This study investigated the effect of dietary supplementation with linoleic acid (LA, 18: 2, n-6) on parturition. Ewes were fed a control or LA-supplemented diet from 100 days gestation. Labour was induced using a standardized glucocorticoid challenge (dexamethasone, Dex) to the fetus, starting on day 139. Electromyographic (EMG) activity and fetal and maternal circulating PG concentrations were monitored. One third of LA-fed ewes delivered early (pre-Dex) although basal uterine EMG activity preceding Dex was higher in control ewes (P < 0.05). A steep increase in EMG activity occurred 18-38 h after the start of Dex infusion. Twice basal EMG activity (defined as established labour) occurred on average 7 h earlier in the LA-supplemented ewes (P < 0.05). The basal concentrations of maternal and fetal PGFM and fetal PGE(2) were approximately doubled in LA-supplemented ewes before the start of Dex infusion (P < 0.01). The rise in fetal PGE(2) and maternal oestradiol concentrations post-Dex occurred earlier in the LA-supplemented ewes. All PG measurements remained significantly higher in the LA-supplemented ewes during labour onset. This study suggests that consumption of a high LA diet in late pregnancy can enhance placental PG production and may thus increase the risk of preterm labour.

Abstract
Since the late 1980s, elevated levels of mercury have been reported in the tissues of the Florida panther (Puma concolor coryi) from the Florida Everglades. The extent, degree, and length of time of mercury contamination in the Florida panther are unknown. The objective of this study was to determine the historical and other patterns of monomethyl and inorganic mercury in the Florida panther by analysis of mercury in panther hair from museum collections. In addition, this study evaluated the effects of preservation of skins on mercury concentrations in hair and the representativeness of museum collections for evaluating historical trends of contamination in the Florida panther. Hair from 42 Florida panther specimens collected from 1896 to 1995 was analyzed for both monomethyl and inorganic mercury. Monomethyl mercury (MMHg) and inorganic mercury (IHg) were found in all specimens. Monomethyl mercury in hair from untanned skins was significantly higher than MMHg in hair from tanned skins. For untanned specimens, the mean MMHg concentration in hair was 1.62 +/- 1.87 mug/g (range 0.11 to 6.68 mug/g, n = 16). Monomethyl mercury accounted for 88% of the total mercury in untanned Florida panther hair. No sexual or geographical differences were found. Although MMHg is generally stable in hair, the tanning process appears to reduce the amount of MMHg in hair. In addition, exogenous IHg contamination of the panther hair was found in museum specimens, especially in older specimens. The implication of these and other factors in interpreting results of museum studies is discussed. The presence of MMHg in panther hair since the 1890s indicates long-term and widespread exposure of the Florida panther to mercury. Levels of MMHg are significantly greater in the 1990s than the 1890s. When combined with field studies of mercury in the Florida panther, considerable individual variability is observed, reflecting short-term changes in exposure of individual panthers to mercury. Although museum specimens showed a significant increase in MMHg over the last 100 years, they did not show the magnitude of increase that field populations of Florida panthers did. A number of Florida panthers appeared to be at risk from mercury over their lifetimes, especially individuals from the early 1990s.

Abstract
Research has demonstrated that the simultaneous determination of waist circumference and fasting plasma triglyceride (TG) concentrations can identify men characterized by a metabolic triad of unconventional risk variables: increased levels of fasting insulin, apolipoprotein (apo) B, and a predominance of small, dense, low density lipoprotein (LDL) particles. The aim of this study was to assess the efficacy of using "hypertriglyceridemic waist" to identify individuals at high risk of CVD in a sample of indigenous Australian women, for whom 2 of the 3 non-traditional risk factors were measured (apo B and insulin). Subjects (N=80) were divided into subgroups on the basis of waist girth and TG levels. The TG/HDL ratio increased in women with both elevated waist (above 95 cm) and TG levels (above 2.0 mmol/L), who were also characterized by lower HDL and elevated LDL concentrations. Although there was no trend toward an increase in apo B with increasing waist girth and TG levels, apo B concentration was highest among subgroups with elevated waist and TG levels. Fasting insulin levels were higher with increasing waist girth, but not with increasing TG levels. Utilizing hypertriglyceridemic waist as a marker of high plasma insulin and apo B can be an important factor in assessing cardiovascular risk in indigenous Australian women, despite an unexpected apo B distribution.

Abstract
A retrospective audit of women with three consecutive inadequate cervical smears during 1998-99 was conducted at Birmingham Heartlands Hospital. The commonest reasons were obscured by polymorphs (34.5%) and sparse cellularity (28.9%). Seventy-three per cent (73%) were followed up at colposcopy and 22.1% had histological assessment; 15.9% of women had an abnormality detected, 10.6% with abnormal histology and 5.3% with a cytological abnormality only. Cytological abnormalities were seen in 11.1% of the screening population. This study did not identify a cytological criterion to differentiate those that would or would not have an abnormality on follow-up. It is suggested that all women with three consecutive inadequate smears should have adequate follow-up, although this may place increased demands on colposcopy services.

Abstract
OBJECTIVE To evaluate dexmedetomidine for sedation of patients in the medical ICU. DESIGN AND SETTING Prospective observational study in an intensive care unit of a university hospital. PATIENTS. Twelve ventilated patients with median APACHE II score 23 (range 10-26). INTERVENTIONS Patients received a loading dexmedetomidine infusion of 1 microg x kg(-1) over 10 min followed by a maintenance infusion rate of 0.2-0.7 microg x kg(-1) x h(-1) for up to 7 days. After experience with the first four patients this maintenance rate of infusion was increased to a maximum of 2.5 microg kg(-1) x h(-1). If required, propofol and morphine provided rescue sedation and analgesia, respectively. RESULTS The first four patients with dexmedetomidine infusion at 0.7 microg x kg(-1) x h(-1)all required rescue sedation with a propofol infusion. A protocol amendment allowed the next eight patients to receive higher dexmedetomidine infusions (mean 1.0+/- microg x kg(-1) x h(-1)). Five of the next eight patients did not required propofol, and two patients only required minimal propofol infusions (20-40 mg x h(-1)). A further patient, with hepatic encephalopathy, required a propofol at 50-100 mg x h(-1). Only modest falls in arterial pressure, heart rate and cardiac output were seen, and no rebound sequelae occurred on discontinuation of dexmedetomidine. Adverse cardiovascular events were nearly all confined to the initial loading dose period of dexmedetomidine. CONCLUSIONS Sedation with dexmedetomidine is efficacious in critically ill medical patients requiring mechanical ventilation in the intensive care unit. A reduction in loading infusion is advised, but higher maintenance infusions may be required to that seen previously in the postoperative ICU patient.
