Abstract
IMPORTANCE Untreated asymptomatic bacteriuria (ASB) has been associated with adverse pregnancy outcomes, including pyelonephritis, preterm labor, and low birth weight infants. Thus, routine screening by standard urine culture (SUC) and treatment of ASB are currently recommended for all pregnant women. For this purpose, some researchers claim that vaginal swabs and urine samples can be used as proxies for each other. Because SUC often misses microbes, we used two more sensitive, recently validated detection methods to compare the composition of the urinary and vaginal microbiomes of pregnant females in their first trimester. Both methods yielded similar results. Vaginal and urinary microbial compositions for the same individual were significantly correlated; however, they were not equivalent. We argue that first trimester urinary and vaginal microbiomes are distinct enough to preclude their use as proxies for each other.

Abstract
Prior studies have identified the associations between environmental phenol and paraben exposures and increased risk of gestational diabetes mellitus (GDM), but no study addressed these exposures as mixtures. As methods have emerged to better assess exposures to multiple chemicals, our study aimed to apply Bayesian kernel machine regression (BKMR) to evaluate the association between phenol and paraben mixtures and GDM. This study included 64 GDM cases and 237 obstetric patient controls from the University of Oklahoma Medical Center. Mid-pregnancy spot urine samples were collected to quantify concentrations of bisphenol A (BPA), benzophenone-3, triclosan, 2,4-dichlorophenol, 2,5-dichlorophenol, butylparaben, methylparaben, and propylparaben. Multivariable logistic regression was used to evaluate the associations between individual chemical biomarkers and GDM while controlling for confounding. We used probit implementation of BKMR with hierarchical variable selection to estimate the mean difference in GDM probability for each component of the phenol and paraben mixtures while controlling for the correlation among the chemical biomarkers. When analyzing individual chemicals using logistic regression, benzophenone-3 was positively associated with GDM [adjusted odds ratio (aOR) per interquartile range (IQR) = 1.54, 95% confidence interval (CI) 1.15, 2.08], while BPA was negatively associated with GDM (aOR 0.61, 95% CI 0.37, 0.99). In probit-BKMR analysis, an increase in z-score transformed log urinary concentrations of benzophenone-3 from the 10th to 90th percentile was associated with an increase in the estimated difference in the probability of GDM (0.67, 95% Credible Interval 0.04, 1.30), holding other chemicals fixed at their medians. No associations were identified between other chemical biomarkers and GDM in the BKMR analyses. We observed that the association of BPA and GDM was attenuated when accounting for correlated phenols and parabens, suggesting the importance of addressing chemical mixtures in perinatal environmental exposure studies. Additional prospective investigations will increase the understanding of the relationship between benzophenone-3 exposure and GDM development.

Abstract
Previous studies suggest arsenic exposure may increase the risk of gestational diabetes mellitus (GDM). However, prior assessments of total arsenic concentrations have not distinguished between toxic and nontoxic species. Our study aimed to investigate the relationships between inorganic arsenic exposure, arsenic methylation capacity, and GDM. Sixty-four cases of GDM and 237 controls were analyzed for urinary concentrations of inorganic arsenic species and their metabolites (arsenite (As3), arsenate (As5), monomethylarsonic acid (MMA), and dimethylarsinic acid (DMA)), and organic forms of arsenic. Inorganic arsenic exposure was defined as the sum of inorganic and methylated arsenic species (iSumAs). Methylation capacity indices were calculated as the percentage of inorganic arsenic species [iAs% = (As3 + As5)/iSumAs, MMA% = MMA/iSumAs, and DMA% = DMA/iSumAs]. Multivariable logistic regression was performed to evaluate the association between inorganic arsenic exposure, methylation capacity indices, and GDM. We did not observe evidence of a positive association between iSumAs and GDM. However, women with GDM had an increased odds of inefficient methylation capacity when comparing the highest and lowest tertiles of iAs% (adjusted odds ratio (aOR) = 1.48, 95% CI 0.58-3.77) and MMA% (aOR = 1.95 (95% CI 0.81-4.70) and a reduced odds of efficient methylation capacity as indicated by DMA% (aOR = 0.62 (95% CI 0.25-1.52), though the confidence intervals included the null value. While the observed associations with arsenic methylation indices were imprecise and warrant cautious interpretation, the direction and magnitude of the relative measures reflected a pattern of lower detoxification of inorganic arsenic exposures among women with GDM.

Abstract
Diet manipulation and genetic selection are two important mitigation strategies for reducing enteric methane (CH4) emissions from ruminant livestock. The aim of this study was to assess whether the diurnal pattern of CH4 emissions from individual dairy cows changes over time when cows are fed on diets varying in forage composition. Emissions of CH4 from 36 cows were measured during milking in an automatic (robotic) milking station in three consecutive feeding periods, for a total of 84 days. In Periods 1 and 2, the 36 cows were fed a high-forage partial mixed ration (PMR) containing 75% forage, with either a high grass silage or high maize silage content. In Period 3, cows were fed a commercial PMR containing 69% forage. Cows were offered PMR ad libitum plus concentrates during milking and CH4 emitted by individual cows was sampled during 8662 milkings. A linear mixed model was used to assess differences among cows, feeding periods and time of day. Considerable variation was observed among cows in daily mean and diurnal patterns of CH4 emissions. On average, cows produced less CH4 when fed on the commercial PMR in feeding Period 3 than when the same cows were fed on high-forage diets in feeding Periods 1 and 2. The average diurnal pattern for CH4 emissions did not significantly change between feeding periods and as lactation progressed. Emissions of CH4 were positively associated with dry matter (DM) intake and forage DM intake. It is concluded that if the management of feed allocation remains constant then the diurnal pattern of CH4 emissions from dairy cows will not necessarily alter over time. A change in diet composition may bring about an increase or decrease in absolute emissions over a 24-h period without significantly changing the diurnal pattern unless management of feed allocation changes. These findings are important for CH4 monitoring techniques that involve taking measurements over short periods within a day rather than complete 24-h observations.

Abstract
OBJECTIVE The objective of this study is to evaluate poor maternal nutrition, environmental exposures and vasoactive stimulants as potential risk factors for gastroschisis. METHODS A case-control study was conducted among singleton pregnancies diagnosed in a tertiary teaching hospital in a 22-month period. Cases of gastroschisis were matched to controls at the time of diagnosis by race and maternal age. Demographics, periconceptual exposures, nutritional biomarkers, and illicit drug hair analysis were evaluated. Analyses were performed using conditional logistic regression. RESULTS Thirty gastroschisis cases and 76 controls were studied with no associations observed for illicit drug use or serum levels of ferritin, iron, B6, B12, folate, or zinc. Neither prescription medication nor over the counter mediation use differed between cases and controls. Following adjustment for insurance, education, low BMI, and nulliparity, mothers of gastroschisis cases had an increased odds of alcohol use 1 month prior and/or during early pregnancy compared with controls, with adjusted odds ratio (OR) 3.19 (95% CI 1.01-11.61). CONCLUSIONS Our findings suggest that further investigation of vasoactive stimulants such as alcohol is warranted in the search to identify risk factors for gastroschisis.

Abstract
CONTEXT Minority communities are disproportionately affected by diabetes, and minority women are at an increased risk for glucose intolerance (dysglycemia) during pregnancy. OBJECTIVES In pregnant American Indian women, the objectives of the study were to use current criteria to estimate the prevalence of first-trimester (Tr1) dysglycemia and second-trimester (Tr2) incidence of gestational diabetes mellitus (GDM) and to explore new candidate measures and identify associated clinical factors. DESIGN This was a prospective cohort study. In Tr1 we performed a 75-g, 2-hour oral glucose tolerance test (OGTT) and glycated hemoglobin (HbA1c) to determine the following: fasting insulin; homeostasis model assessment of insulin resistance; serum 1,5-anhydroglucitol; noninvasive skin autofluorescence (SCOUT). We defined dysglycemia by American Diabetes Association and Endocrine Society criteria and as HbA1c of 5.7% or greater. In Tr2 in an available subset, we performed a repeat OGTT and SCOUT. PARTICIPANTS Pregnant American Indian women (n = 244 at Tr1; n = 114 at Tr2) participated in the study. OUTCOMES The prevalence of dysglycemia at Tr1 and incidence of GDM at Tr2 were measured. RESULTS At Tr1, one woman had overt diabetes; 36 (15%) had impaired glucose tolerance (American Diabetes Association criteria and/or abnormal HbA1c) and 59 (24%) had GDM-Tr1 (Endocrine Society criteria). Overall, 74 (30%) had some form of dysglycemia. Associated factors were body mass index, hypertension, waist/hip circumferences, SCOUT score, fasting insulin, and homeostasis model assessment of insulin resistance. At Tr2, 114 of the Tr1 cohort underwent a repeat OGTT and SCOUT, and 26 (23%) had GDM. GDM-Tr2 was associated with increased SCOUT scores (P = .029) and Tr1 body mass index, waist/hip circumferences, diastolic blood pressure, fasting insulin, and triglyceride levels. Overall, dysglycemia at Tr1 and/or Tr2 affected 38% of the women. CONCLUSIONS Dysglycemia at some point during pregnancy was common among American Indian women. It was associated with features of insulin resistance and may confer long-term health risks for mother and child.

Abstract
Recent epidemiological studies indicate bisphenol A (BPA), an estrogenic chemical used in production of epoxy, polycarbonate, and plastic may increase risk of insulin resistance and type 2 diabetes. Exposure to BPA during pregnancy may contribute to development of gestational diabetes mellitus (GDM), a precursor to type 2 diabetes in women. This pilot study examined the association between BPA exposure, fasting blood glucose levels (FBG), and GDM diagnosis during pregnancy. Banked urine samples from 22 cases of GDM and 72 controls were analyzed for total (free BPA + conjugates) urinary BPA concentrations (μg/L). FBG levels (mg/dl) were obtained from 1-h 50-g glucose tolerance tests (GTT) that women underwent for routine GDM screening (mean gestational age = 26.6 weeks, SD = 3.8). Those with an initial screening value ≥ 135 mg/dl underwent 3-h 100 g oral GTT. GDM diagnoses were made when the initial screening value was ≥ 200 mg/dl or when values at ≥ 2 time points exceeded 3-h oral GTT thresholds. Among controls, median FBG levels (mg/dL) did not differ across exposure tertiles, defined according to the distribution of total specific-gravity-adjusted urinary BPA concentrations. Logistic regression models controlling for race/ethnicity did not provide evidence of association between BPA exposure and case status across increasing tertiles of BPA exposure (number of GDM cases/controls in tertile1: 13/24; in tertile 2: 6/24; in tertile 3: 3/24). Findings do not support a relationship between total urinary BPA concentrations and altered glucose metabolism during pregnancy. However, due to study limitations, findings need to be interpreted with caution.

METHODS This was a retrospective cohort study of all women in labor delivered by cesarean section (CS) from November 2004 through December 2006. The study population was dichotomized by previous CS and compared for various maternal and neonatal outcomes. Student t-test, χ² and Fisher exact tests were used for analysis. RESULTS There was a significantly higher rate of symptomatic uterine rupture [3/100 (3%) vs. 0/449 (0%), p = 0.006], asymptomatic uterine scar dehiscence [6/100 (6%) vs. 0/449 (0%), p = 0.0001], and bladder injury [2/100 (2%) vs. 0/100 (0%), p = 0.001], among women with prior cesarean delivery compared to those without. The rate of respiratory distress syndrome [(6/100) (6%) vs. 10/449 (2.2%), p = 0.05] and meconium aspiration [4/100 (4%) vs. 2/449 (0.4%), p = 0.01] was also significantly higher among neonates of women with prior cesarean delivery. However, the rate of endomyometritis [3/100 (3%) vs. 50/449 (11.1%), p = 0.009] and febrile morbidity [17/100 (17%) vs. 144/449 (32.1%), p = 0.003] was significantly lower among women with prior cesarean delivery compared to those without prior cesarean birth. CONCLUSIONS Compared to laboring women without previous cesarean delivery, women with previous cesarean delivery have increased maternal and neonatal morbidity. Febrile morbidity was, however, lower among women with previous cesarean delivery. These differential findings should further inform our perinatal counseling of women contemplating trial of labor after a previous cesarean delivery.

Abstract
OBJECTIVE We sought to evaluate whether group B streptococcus (GBS) detection is altered by the digital cervical examination. STUDY DESIGN A total of 302 women undergoing the clinical GBS culture had a digital cervical examination and a repeated GBS culture. Statistical comparison of pre-post culture results were performed with kappa and McNemar tests. RESULTS The clinical prevalence of GBS was 19.5%. Discordant results were seen in 30/302 (9.9%) paired cultures (kappa = 0.68; 95% confidence interval, 0.568-0.783). An initially negative GBS culture result was positive on repeated testing in 13/243 (5.3%) pairs. Initially positive cultures were negative on repeated testing in 17/59 (28.8%) pairs. Patients with discordant results had similar characteristics as the remainder of the study group. Given the observed proportion of discordant results (9.9%), the study had 80% power to detect a 5% difference between discordant pairs. CONCLUSION Paired GBS cultures showed a good level of agreement. The 28.8% rate of positive cultures becoming negative is clinically concerning and warrants further study.

Abstract
Periventricular heterotopia (PH) represents a neuronal migration disorder that results in gray matter nodules along the lateral ventricles beneath an otherwise normal appearing cortex. While prior reports have shown that mutations in the filamin A (FLNA) gene can cause X-linked dominant PH, an increasing number of studies suggest the existence of additional PH syndromes. Further classification of these cortical malformation syndromes associated with PH allows for determination of the causal genes. Here we report three familial cases of PH with hydrocephalus. One pedigree has a known FLNA mutation with hydrocephalus occurring in the setting of valproic acid exposure. Another pedigree demonstrated possible linkage to the Xq28 locus including FLNA, although uncharacteristically a male was affected and sequencing of the FLNA gene in this individual revealed no mutation. However, in the third family with an autosomal mode of inheritance, microsatellite analysis ruled out linkage with the FLNA gene. Routine karyotyping and fluorescent in situ hybridization using BAC probes localized to FLNA also showed no evidence of genomic rearrangement. Western blot analysis of one of the affected individuals demonstrated normal expression of the FLNA protein. Lastly, sequencing of greater than 95% of the FLNA gene in an affected member failed to demonstrate a mutation. In conclusion, these findings demonstrate the etiological heterogeneity of PH with hydrocephalus. Furthermore, there likely exists an autosomal PH gene, distinct from the previously described X-linked and autosomal recessive forms. Affected individuals have severe developmental delay and may have radiographic findings of hydrocephalus.

Abstract
AIMS The ability to predict the morbidity of retained deciduous teeth with no permanent successors, a characteristic of hypodontia, would be of considerable value in treatment planning, but is hampered by lack of data. METHODS This problem was studied using 356 orthopantomogram radiographs (OPGs) from the records of 249 patients who had attended a specialist hypodontia clinic, and had retained deciduous teeth with no permanent successors. Due to their clinical importance, canine and molar teeth were chosen for examination. Resorption was assessed subjectively by three experienced clinicians. RESULTS Un-weighted Kappa values for reproducibility were > 0.8, and for interobserver error 0.60-0.83. Gender related differences were minimal. Regardless of gender or radiographic age, the lower canines appear to show the least amount of resorption and the upper first molars the most. The upper and lower second molars have particularly unpredictable life spans. Whilst the lower first molars have a predictable life span that is poor, the life span for the upper first molars is slightly worse. CONCLUSIONS Lower canines have a predictable life span that appears to be good, as do upper canines, but of lesser duration than lower canines. Molars have poorer and less predictable life spans.

Abstract
In the human pregnant state a high molecular weight form of angiotensinogen (HMrA) is present in significant quantities in addition to the usual low molecular weight angiotensinogen (LMrA). In a previous study involving a small number of white women, it was found that women who had developed pregnancy-induced hypertension (PIH) had significantly higher levels of plasma HMrA. It has been determined that there are five isoforms of HMrA. The objectives of this study were to expand the previous study with the inclusion of black women and to determine which isoform(s) of plasma HMrA are elevated in PIH. Plasma LMrA and HMrA were quantitated in 24 normotensive pregnant women and 65 women with PIH. The PIH group had higher levels of HMrA and somewhat lower levels of LMrA than the normotensive group. The HMrA/LMrA ratio was elevated in 47% of the PIH group. The five isoforms of HMrA were quantitated in plasma from 10 white women with PIH, 10 black women with PIH, and 6 normotensive pregnant white women. Half of both the white and black women with PIH had an elevated HMrA/LMrA ratio. The relative proportion of the HMrA isomers was similar in all groups. These studies show that half the women with PIH have a distinct abnormality in their renin angiotensin system. Both white and black women show this abnormality. In those women who have an elevated total HMrA, all five isoforms of HMrA are equally elevated.

Abstract
Incontinentia Pigmenti (Bloch-Sulzberger syndrome) is an uncommon genodermatosis that usually affects female infants. The condition is characterized by four cutaneous stages and is frequently associated with dental, ocular, central nervous system and structural anomalies. A large case series of seven patients, all female, who presented to the Department of Paediatric Dentistry at the Eastman Dental Hospital over the last 16 years is reported. The dental features of these cases were typical and included missing teeth, microdontia and delayed eruption. In two of the seven cases, both maxillary canines were palatally impacted.

Abstract
Heat and moisture exchangers (HMEs) have been used for more than 30 years for heat and moisture retention during general anesthesia. Studies about bacteriostatic vs nonbacteriostatic HMEs (BHMEs/NHMEs) have been conducted to assess their role in preventing bacterial transmission to the anesthesia breathing circuit; none have been done on anesthetized patients in the operating room. The present study adds to existing knowledge about the HME's ability to prevent transmission of bacteria, with implications for cost reduction resulting from reuse of anesthesia breathing circuits among patients. The chi 2 test revealed no statistically significant differences between groups in transmission of bacteria from endotracheal tube (ETT) to anesthesia breathing circuit (P = .48). However, both groups showed statistically significant differences between presence of bacteria in ETTs and anesthesia breathing circuits: Group 1, BHME (P < .005) and group 2, NHME (P < .005). Neither HME prevented contamination of the machine side of the circuit. These results support not reusing breathing circuits. Of 53 participants in group 2, 28 had positive ETT cultures with 7 showing transmission to anesthesia breathing circuit. Of 46 participants in group 1, 28 had positive ETT cultures with 9 showing transmission to anesthesia breathing circuit.

Abstract
Mycobacterium avium is an intracellular pathogen that is associated with disseminated infection in acquired immunodeficiency syndrome (AIDS). Patients with AIDS appear to acquire M. avium mainly through the gastrointestinal tract. Previous studies have shown that healthy mice given M. avium orally develop disseminated infection after 2-4 weeks. The chief site of M. avium invasion of the intestinal mucosa is the terminal ileum. To learn more about the pathophysiology of M. avium infection of the intestinal mucosa, C57BL/6 bg+ bg+ mice were infected orally with M. avium strain 101 and groups of six mice were killed each week for 8 weeks. The terminal ileum was then prepared for histopathological studies and electron microscopy. A delayed inflammatory response was observed and influx of neutrophils in the Peyer's patches was the only abnormality seen at 1 week. A severe inflammatory response was seen from week 2 to week 5 and necrosis of intestinal villi was observed 6 weeks after infection. These results indicate that invasion and infection of the normal intestine by M. avium results in a severe inflammatory response with segmental necrosis of the intestinal mucosa.

Abstract
OBJECTIVE To review a series of cases of hypophosphataemic vitamin D resistant rickets. SUBJECTS INCLUDED: Seventeen cases, aged between 2 years 1 month and 15 years 9 months at first referral, and with an established diagnosis of vitamin D resistant rickets from twelve families were included in the review. Information was drawn from patient records for follow-up periods between 9 months and 20 years 4 months. SETTING All subjects had been referred to the Eastman Dental Hospital between 1973 and 1997. FINDINGS Abscessed non-carious primary and/or permanent teeth were a presenting feature in eleven of the seventeen cases. Although attrition and exposure of the abnormally formed dentine accounted for the route of infection in primary teeth, the route for microbial invasion of pulpal tissues in permanent teeth remained unexplained in a number of patients. The possible part played by infractures of the enamel as a portal of entry for infection is discussed. Enamel defects were observed in only six patients, in three of whom these changes were limited to the primary dentition. Taurodontism of permanent molar teeth was confirmed as a feature of the condition in the more severely affected male subjects.

Abstract
Retrospective analysis of 28 children suffering from severe infra-occlusion and/or primary failure of eruption of deciduous molars revealed an association with eruptive and developmental disturbances in the permanent dentition, including ectopically placed teeth and aplasia of teeth. Taurodont permanent molars were evident in 19 of the 28 selected cases which suggests a possible developmental relationship between these factors. Problems in relation to treatment of these cases are discussed.

Abstract
Infections caused by organisms of the Mycobacterium avium complex occur in approximately 50 to 60% of patients with AIDS. M. avium is an intracellular pathogen that survives and multiplies within mononuclear phagocytes. In this study, we investigated the uptake of M. avium grown within macrophages (intracellular growth M. avium [IG]) by a second macrophage compared with M. avium cultured in broth (extracellular growth M. avium [EG]). The results showed that IG was six- to eightfold more efficient than EG in entering macrophages. In addition, while an anti-CR3 antibody was able to inhibit approximately 60% of EG uptake by macrophages, it failed to inhibit the entry of IG. In contrast to EG, IG uptake into macrophages was significantly inhibited in the presence of anti-beta1-integrin and anti-transferrin receptor antibodies. Entry into macrophages by alternate receptors was associated with resistance to tumor necrosis factor alpha (TNF-alpha) stimulation. While stimulation with TNF-alpha resulted in inhibition of the growth of EG, it was not associated with inhibition of intracellular growth of IG. Investigation of the reason why M. avium is able to sense the changes in the intracellular environment triggering a change to the invasive phenotype suggests a direct relationship with macrophage apoptosis. These results suggest that intracellular growth is associated with novel mechanisms of M. avium uptake of macrophages and that those mechanisms appear to offer advantages to the bacteria in escaping the host defense.

Abstract
Toxoplasmosis is a parasitic infection which may be asymptomatic or produce lymphadenopathy, fever and malaise. In children the cervical lymph nodes are most commonly affected. This report describes a case of a 9-year-old boy who presented with submandibular lymphadenopathy associated with a non-vital primary tooth, which persisted following extraction of the tooth. A diagnosis of acquired toxoplasmosis was made on the findings of fine-needle aspiration cytology and subsequently confirmed by serological investigations, thus sparing the patient unnecessary hospitalization and surgery. The patient required amitryptyline as a nocturnal sedative and made a complete recovery within a few months without the need for further intervention.

Abstract
Band 3 performs the same structural and functional activities in adult brain as it does in erythrocytes. It ages as cells and tissues age Our studies, to date, indicate that the anion transport ability of band 3 decreases in brains and lymphocytes from old mice. This decreased transport ability precedes obvious structural changes, such as band 3 degradation and generation of SCA and is the earliest change thus far detected in band 3. The following changes occur in lymphocytes, erythrocytes and brain band 3 with aging: 1) a decreased efficiency of anion transport (decreased Vmax) in spite of an increase in number of anion binding sites (increased K(m)), 2) a decreased glucose transport, 3) 32P labeling in vitro, 4) an increased degradation to smaller fragments as detected by quantitative binding of antibodies to band 3 breakdown products and residue 812-830, and 5) a binding of physiologic IgG autoantibodies in situ. The latter three findings indicate that posttranslational changes occur. In addition, the anion transporter, band 3, undergoes an as yet undefined change that results in binding of "980" antibodies to aged band 3. Posttranslational changes in AD include decreased brain and RBC phosphorylation of a M(r) = 135, 113 and 45 kDa band 3 polypeptides due to the phosphorylation site being already occupied, increased degradation of band 3, alterations in band 3 recognized by antibodies, and decreased anion and glucose transport by blood cells. Band 3 in erythrocytes of AD patients has a different immunological identity from normal band 3 as evidenced by the binding of antibodies described in this study. AD may be preferentially manifested in the brain because neurons accumulate damage throughout the lifetime as they do not regenerate or undergo cell division. We suspect, and our data indicate, that the same mechanism(s) of AD occurs in all cells, but that the manifestations differ due to different cell proteins and functions.

Abstract
A survey is presented of the complaints and findings in a group of 451 patients referred to a multidisciplinary clinic for the management of hypodontia. The most common complaints were missing teeth, spacing in the dental arches, and poor appearance. The majority of patients were referred by their dental practitioners, and more than half were over 12 years old when first seen. Delayed referral can have educational and social consequences. Changing attitudes to dental care and the maintenance of an intact dentition are resulting in hypodontia, particularly in its more severe forms, becoming of increasing concern to children and their parents. The management of this condition is best organised via multidisciplinary specialist clinics.

Abstract
The anion transport, "band 3," family of proteins in mammalian brain performs the same functions as that of erythroid band 3. These functions are anion transport, ankyrin binding, and generation of senescent cell antigen, an aging antigen that terminates the life of cells. The presence of 5-7 band 3 related proteins in brain tissue was suggested by the reaction of antibodies to synthetic peptides of erythroid band 3 with a number of bands in immunoblots. Since there are a number of different cell types in brain, tissue cultures of neural cell types were examined to determine whether multiple band 3 related proteins are present in each cell type or whether several band 3 related proteins are present in each cell type. The tumor cell lines exhibit anion transport and are inhibited by the anion transport inhibitors 4,4'-diisothiocyano-2,2' disulfonic acid (DIDS), phenylglyoxal, and furosemide. Glucose transport is inhibited by cytochalasin B and the anion transport inhibitor, phenylglyoxal, in these cell lines, but not by 4,4'-diisothiocyano-2,2' disulfonic acid. Furosemide gave partial inhibition of most, but not all, cell lines. Since phenylglyoxal inhibits anion transport by binding to an arginine near the transport site, inhibition of glucose transport by phenylglyoxal suggests that an arginine lies in the substrate binding site. The number of cytochalasin B and DIDS binding sites was quantitated on cell lines as an approximation of the number of glucose transporter and anion transporter sites, respectively.

Abstract
Osteopathia striata is an unusual skeletal condition that can affect the bones of the skull quite markedly and result in dental problems that have rarely been discussed in the literature. The characteristic features exhibited by the patient in this case report were dense maxillary and mandibular bone, a high forehead with frontal bossing, a broad nasal bridge, prominent zygomatic arches and thickened angles of the mandible. The mouth opening was limited as a result of sclerosis of the mastoid process, and right lateral excursion of the mandible was reduced, probably because of a deformity of the left condyle.

Abstract
Some concern has been expressed in recent years about the use of formocresol for vital pulpotomy treatment of primary molars. This paper reviews the literature concerning the toxicity of formocresol and considers the evidence for the use of calcium hydroxide and glutaraldehyde. It is concluded that more work is required in this field before an alternative to formocresol can be recommended and that, in the meantime, a 1:5 dilution of the standard formocresol solution should be used but not included in the zinc oxide-eugenol sublining.

Abstract
Oxygen conserving devices, the TTO catheters, electronic pulsed DODS and reservoir cannulas, increase efficacy of oxygen delivery; TTO also improves cosmetic appearance, comfort and compliance. We speculated that pulsing of oxygen transtracheally can increase efficiency of TTO. We modified the DODS to include settable delays and a rapid pre-inspiratory trigger. The first part of the study was performed with nasal oxygen on seven subjects and the second part, with TTO on 17 subjects. Nasal oxygen results indicate improved delivery efficiency with more rapid response. The TTO results indicate no significant change for each delay setting, but there was improvement in delivery efficiency when DODS was combined with TTO vs continuous flow TTO. Thus, early inspiratory delivery increases efficiency of oxygen therapy. Small delays in response time are critical in nasal delivery but not important in TTO. Pulsed TTO is more efficient than continuous flow TTO and merits long-term studies.

Abstract
The Magnetip* double J type ureteral stent has been used in a wide variety of clinical urological settings. We reviewed the use of the stent in 50 patients. In 45 patients stents were placed in conjunction with extracorporeal shock wave lithotripsy, stone manipulation, obstruction due to pregnancy or malignancy, pyeloplasty and ureteroneocystostomy. In 83 per cent of the attempts the stent was placed successfully. Retrieval with the Magnetriever* was accomplished in 86 per cent of the cases (100 per cent in female and 76 per cent in male patients). Details of stent use are described.

Abstract
Removable partial dentures (RPDs) are frequently used in the treatment of severe hypodontia. The failure rates and modes of failure of 138 such prostheses incorporating acrylic resin onlays were assessed in a retrospective survey. Failures primarily occurred either early or late in the life of the prostheses. Particular problems identified were the low wear resistance of acrylic resin onlays and poor fixation of resin components to metal bases, especially when space was limited.

Abstract
Over a 2-year period, the safety and efficacy of a program specifically designed for transtracheal oxygen therapy were evaluated in 100 patients with chronic hypoxemia. The four clinically defined phases of the program included patient orientation, evaluation, and selection (phase I); a new needle-wire guide-dilator transtracheal procedure and stent week (phase II); transtracheal oxygen delivery with an immature tract (phase III); and transtracheal oxygen delivery with a mature tract (phase IV). Sequelae and complications were minor, and patient acceptance was high. As compared with the nasal cannula, the transtracheal catheter was associated with a significant reduction in oxygen flow requirement during both rest and exercise. Adequate oxygenation was maintained over time, and erythrocythemia was alleviated with transtracheal delivery. We conclude that transtracheal oxygenation by this method has a low, acceptable morbidity; it is more efficient than nasal cannula delivery and may be more effective in some patients.

Abstract
The combination of interstitial nephritis and minimal-change nephrotic syndrome has been well described in adults receiving nonsteroidal anti-inflammatory agents. The association of interstitial nephritis and minimal-change nephrotic syndrome has recently been described in 1 adult patient receiving ampicillin and in 1 patient receiving rifampin. We describe an 8-month-old child who developed reversible interstitial nephritis and minimal-change nephrotic syndrome while taking antibiotics.

Abstract
It is easy to distort the "truth" in morphological reports in order to confirm a previously established dogma by selecting from a field of view only such details which are in accordance with the dogma and by ignoring parts contradictory to it. The renal corpuscle is used in this paper as an example and as a guide to the readers for future fraud.

Abstract
Band 3, the major transmembrane polypeptide of erythrocytes, mediates the exchange of anions (chloride and bicarbonate) across the membrane. We suspected that band 3 was present on nucleated somatic cells as well as erythrocytes because the senescent cell antigen that is immunologically related to band 3 is present on lymphocytes, platelets, adult liver cells, and embryonic kidney cells; and antibodies prepared against the senescent cell antigen isolated from leukocytes react with erythrocyte band 3. For this reason, we examined human fibroblasts, lung cells, neutrophils, mononuclear leukocytes, squamous epithelial (mouth) cells, lung squamous epithelial carcinoma, mouse neuroblastoma cells, and rat hepatocytes for immunoreactive forms of band 3 by using monospecific antibodies to erythrocyte band 3. The results demonstrated that polypeptides sharing common antigenic determinants with erythrocyte band 3 are present in nucleated somatic cells as determined by immunofluorescence, immunoelectron microscopy, and immunoautoradiography. Peptide mapping revealed substantial sequence homology between erythrocyte band 3 and the band 3-like protein of leukocytes. Immunofluorescence studies indicate that the band 3-like proteins in nucleated cells participate in antibody-induced cell surface capping.

Abstract
The distribution of calcium phosphate granules in mitochondria of proximal and distal renal tubules of nonuremic and uremic children was analyzed by electron microscopy of material obtained by percutaneous kidney biopsy. Although distal tubule had fewer granules/mitochondrion than proximal tubule, uremia induced a significant drop (50%) in both, related to an increase in mitochondria containing O granules and a decrease in mitochondria with 2+ granules. The decrease observed in uremic children was reproduced experimentally by partial nephrectomy in rats. Uremia resulted in a 58% decrease of calcium phosphate granules in rat proximal tubule while a smaller but significant decrease (36%) occurred in distal tubule. Vitamin D deficiency in rats was associated with greatly decreased granulation in proximal tubule (80%) whereas distal tubule was less severely affected (36%). Supplementation of vitamin D to uremic rats restored mitochondrial granulation to normal in proximal tubule in 24 hr, but had no effect in distal tubule since the number of granules/mitochondrion, 0.5 +/- 0.1, remained statistically similar to that of untreated animals. Granulation in both proximal and distal tubule of uremic rats was unaffected by parathyroid hormone administration. Since restoration of granulation occurred only in proximal tubule, the defect in uremia which can be overcome by vitamin D treatment appears localized at the level of the proximal tubular cell membrane, indicating an action of vitamin D on calcium and/or phosphorus translocation into the proximal tubule.

Abstract
Lamination of the basement membrane has been considered to be the lesion characteristic of familial nephritis and attenuation to be the lesion of "Benign" familial hematuria. Electron micrographs were reviewed of 57 children who had renal biopsies for persistent hematuria. Attenuation or lamination of the glomerular capillary basement membrane was found in each. Twenty of the 57 children had familial nephritis; 20 had familial hematuria; and 17 had no involved relatives. Follow-up data were available for 14 of 20 children with familial nephritis, 12 of 20 with familial hematuria, and 12 of 17 with sporadic hematuria for 13.6 +/- 6.3, 6.7 +/- 4.6, and 7.0 +/- 4.8 years, respectively, after discovery of hematuria. Five children developed end-stage renal disease: three with familial nephritis, one with familial hematuria, and one with sporadic hematuria. Only two no longer had hematuria. Attenuation of the glomerular capillary basement membrane was seen in every biopsy, whereas lamination was not. Because hematuria and ultrastructural abnormalities were findings shared by all the children, we suggest the possibility that familial nephritis, and familial or sporadic hematuria as defined in this study, may be variations in a spectrum of inherited abnormality or abnormalities in the formation of the glomerular capillary basement membrane.
