Radakovich, Nathan, Meggendorfer, Manja, Malcovati, Luca, Hilton, C. Beau, Sekeres, Mikkael A., Shreve, Jacob, Rouphail, Yazan, Walter, Wencke, Hutter, Stephan, Galli, Anna, Pozzi, Sara, Elena, Chiara, Padron, Eric, Savona, Michael R., Gerds, Aaron T., Mukherjee, Sudipto, Nagata, Yasunobu, Komrokji, Rami S., Jha, Babal K., Haferlach, Claudia, Maciejewski, Jaroslaw P., Haferlach, Torsten, and Nazha, Aziz

Abstract

The differential diagnosis of myeloid malignancies is challenging and subject to interobserver variability. We used clinical and next-generation sequencing (NGS) data to develop a machine learning model for the diagnosis of myeloid malignancies independent of bone marrow biopsy data based on a 3-institution, international cohort of patients. The model achieves high performance, with model interpretations indicating that it relies on factors similar to those used by clinicians. In addition, we describe associations between NGS findings and clinically important phenotypes and introduce the use of machine learning algorithms to elucidate clinicogenomic relationships.

7. Hypervariable Pili and Flagella Genes Provide Suitable New Targets for DNA High-Resolution Melt-Based Genotyping of Dairy Geobacillusspp.

Author

Chauhan, Kanika, Seale, R. Brent, Deeth, Hilton C., and Turner, Mark S.

Abstract

Although nonpathogenic in nature, spores of Geobacillusare able to attach to surfaces, germinate, and form biofilms, allowing rapid multiplication and persistence within milk powder processing plants, causing final product contamination, and eventually leading to a loss of revenue in terms of downgraded product quality. As a result, Geobacillusspp. have been found to be common contaminants of milk powder worldwide. Genotyping methods can help in gaining insight into the ecology and transmission of these thermophilic bacteria within and between dairy processing plants. The objective of this study was to use the assembled draft genomes of two Geobacillusspp. to identify and test new hypervariable genotyping targets for differentiating closely related dairy Geobacillusisolates. The two Geobacillusspp. strains obtained from high spore count powders were obtained in 2010 (isolate 7E) and in 1995 (isolate 126) and were previously shown to be of same genotype based on a variable number tandem repeat genotyping method. Significant nucleotide sequence variation was found in genes encoding pili and flagella, which were further investigated as suitable loci for a new high-resolution melt analysis (HRMA)–based genotyping method. Three genes encoding pulG(containing prepilin-type N-terminal cleavage domain), pilT(pili retraction protein), and fliW(flagellar assembly protein) were selected as targets for the new pili/flagella gene (PilFla) HRMA genotyping method. The three-gene-based PilFla-HRMA genotyping method differentiated 35 milk powder Geobacillusspp. isolates into 19 different genotype groups (D= 0.93), which compared favorably to the previous method (which used four variable number tandem repeat loci) that generated 16 different genotype groups (D= 0.90). In conclusion, through comparative genomics of two closely related dairy Geobacillusstrains, we have identified new hypervariable regions that prove to be useful targets for highly discriminatory genotyping.

8. Mortality rates in people dually infected with HIV-12 and those infected with either HIV-1 or HIV-2

Author

Prince, Puck D., Matser, Amy, van Tienen, Carla, Whittle, Hilton C., and Loeff, Maarten F. Schim van der

Abstract

As compared to HIV-1 infection, HIV-2 is less transmissible, disease progression is slower, and the mortality risk is lower. It has been suggested that HIV-2 infection inhibits the progression of HIV-1 in individuals dually infected by HIV-1 and HIV-2 (HIV-D). We examined whether the mortality rates in dually infected individuals differ from those in persons infected with either HIV-1 or HIV-2.

Abstract

Objective Cleft palate increases the risk of chronic middle ear disease and hearing loss. The goal of this report was to determine which of two palate surgeries and which timing of palate surgery were associated with better otologic and audiologic outcomes in children with unilateral cleft lip and palate at 5 to 6 years of age.Design Subjects were randomly assigned to the von Langenbeck with intravelar veloplasty or Furlow palate repair, to palate surgery at 9 to 12 months or 15 to 18 months of age, and to the Spina or Millard lip repair.Setting Centralized, tertiary care craniofacial treatment center.Patients A total of 673 infants with unilateral cleft lip and palate.Interventions Palate and lip were repaired using established techniques. Serial otoscopic and audiometric evaluations were performed.Main Outcome Measures Hearing and otoscopic findings at 5 to 6 years old.Results There were 370 children available for analysis. Hearing and need for tympanostomy tube placement did not differ by palatoplasty, age at palatoplasty, cheiloplasty, or surgeon. Risk of developing cholesteatoma or perforation was higher with Millard cheiloplasty (odds ratio = 5.1, 95% confidence interval = 1.44 to 18.11, p= .012). Type and age at palatoplasty were not significantly associated with either the rate of developing these sequelae or the rate of achieving bilaterally normal hearing and ear examinations.Conclusions Type of palatoplasty did not influence otologic and audiologic outcomes in 5- to 6-year-olds with unilateral cleft lip and palate. The potential influence of lip repair on otologic outcomes warrants further investigation.

Abstract

Objective: To study the growth of children with complete unilateral cleft lip and palate (UCLP) from birth to 2 years of age and to construct specific UCLP growth curves.Design: Physical growth was a secondary outcome measure of a National Institutes of Health–sponsored longitudinal, prospective clinical trial involving the University of Florida (United States) and the University of São Paulo (Brazil).Patients: Six hundred twenty-seven children with UCLP, nonsyndromic, both genders.Methods: Length, weight, and head circumference were prospectively measured for a group of children enrolled in a clinical trial. Median growth curves for the three parameters (length, weight, head circumference) were performed and compared with the median for the National Center for Health Statistics (NCHS) curves. The median values for length, weight, and head circumference at birth and 6, 12, 18, and 24 months of age were plotted against NCHS median values and statistically compared at birth and 24 months.Setting: Hospital de Reabilitação de Anomalias Craniofaciais, Universidade de São Paulo, Bauru, Brazil (HRAC-USP).Results: At birth, children of both genders with UCLP presented with smaller body dimensions in relation to NCHS median values, but the results suggest a catch-up growth for length, weight, and head circumference for girls and for weight (to some degree) and head circumference for boys.Conclusions: Weight was the most compromised parameter for both genders, followed by length and then head circumference. There was no evidence of short stature. This study established growth curves for children with UCLP.

11. Relationship between the Physicochemical Properties of Nonchitinolytic Listeriaand Salmonellaand Their Attachment to Shrimp Carapace

Author

Wan Norhana, M.N., Goulter, Rebecca M., Poole, Susan E., Deeth, Hilton C., and Dykes, Gary A.

Abstract

Listeriaand Salmonellaare important foodborne pathogens normally associated with the shrimp production chain. This study investigated the potential of SalmonellaTyphimurium, SalmonellaSenftenberg, and Listeria monocytogenes(Scott A and V7) to attach to and colonize shrimp carapace. Attachment and colonization of Listeriaand Salmonellawere demonstrated. Shrimp abdominal carapaces showed higher levels of bacterial attachment (P< 0.05) than did head carapaces. Listeriaconsistently exhibited greater attachment (P< 0.05) than did Salmonellaon all surfaces. Chitinase activity of all strains was tested and found not to occur at the three temperatures (10, 25, and 37°C) tested. The surface physicochemical properties of bacterial cells and shrimp carapace were studied to determine their role in attachment and colonization. Salmonellahad significantly (P< 0.05) more positive (−3.9 and −6.0 mV) cell surface charge than Listeria(−18 and −22.8 mV) had. Both bacterial species were found to be hydrophilic (<35%) when measured by the bacterial adherence to hydrocarbon method and by contact angle (θ) measurements (Listeria, 21.3 and 24.8°, and Salmonella, 14.5 and 18.9°). The percentage of cells retained by Phenyl-Sepharose was lower for Salmonella(12.8 to 14.8%) than it was for Listeria(26.5 to 31.4%). The shrimp carapace was found to be hydrophobic (θ = 74.5°), and a significant (P< 0.05) difference in surface roughness between carapace types was noted. There was a linear correlation between bacterial cell surface charge (r2= 0.95) and hydrophobicity (r2= 0.85) and initial attachment (P < 0.05) of Listeriaand Salmonellato carapaces. However, the same properties could not be related to subsequent colonization.

13. Heat-induced and other chemical changes in commercial UHT milks

Author

Elliott, Anthony J, Datta, Nivedita, Amenu, Boka, and Deeth, Hilton C

Abstract

The properties of commercial directly and indirectly heated UHT milks, both after heating and during storage at room temperature for 24 weeks, were studied. Thermally induced changes were examined by changes in lactulose, furosine and acid-soluble whey proteins. The results confirmed previous reports that directly heated UHT milks suffer less heat damage than indirectly heated milk. During storage, furosine increased and bovine serum albumin in directly heat-treated milks decreased significantly. The changes in lactulose, α-lactalbumin and β-lactoglobulin were not statistically significant. The data suggest that heat treatment indicators should be measured as soon as possible after processing to avoid any misinterpretations of the intensity of the heat treatment.

14. Significance of frictional heating for effects of high pressure homogenisation on milk

Author

Datta, Nivedita, Hayes, Maurice G, Deeth, Hilton C, and Kelly, Alan L

Abstract

High pressure homogenisation (HPH) is a novel dairy processing tool, which has many effects on enzymes, microbes, fat globules and proteins in milk. The effects of HPH on milk are due to a combination of shear forces and frictional heating of the milk during processing; the relative importance of these different factors is unclear, and was the focus of this study. The effect of milk inlet temperature (in the range 10–50 °C) on residual plasmin, alkaline phosphatase, lactoperoxidase and lipase activities in raw whole bovine milk homogenised at 200 MPa was investigated. HPH caused significant heating of the milk; outlet temperature increased in a linear fashion (0·5887 °C/°C, R2=0·9994) with increasing inlet temperature. As milk was held for 20 s at the final temperature before cooling, samples of the same milk were heated isothermally in glass capillary tubes for the same time/temperature combinations. Inactivation profiles of alkaline phosphatase in milk were similar for isothermal heating or HPH, indicating that loss of enzyme activity was due to heating alone. Loss of plasmin and lactoperoxidase activity in HPH milk, however, was greater than that in heated milk. Large differences in residual lipase activities in milks subjected to heating or HPH were observed due to the significant increase in lipase activity in homogenised milk. Denaturation of β-lactoglobulin was more extensive following HPH than the equivalent heat treatment. Inactivation of plasmin was correlated with increasing fat/serum interfacial area but was not correlated with denaturation of β-lactoglobulin. Thus, while some effects of HPH on milk are due to thermal effects alone, many are induced by the combination of forces and heating to which the milk is exposed during HPH.

15. Increased levels of aflatoxin-albumin adducts are associated with CYP3A5 polymorphisms in The Gambia, West Africa

Author

Wojnowski, Leszek, Turner, Paul C, Pedersen, Bonnie, Hustert, Elisabeth, Brockmöller, Jürgen, Mendy, Maimuna, Whittle, Hilton C, Kirk, Greg, and Wild, Christopher P

Abstract

Major risk factors for hepatocellular carcinoma (HCC) are hepatitis viruses and exposure to aflatoxins, including aflatoxin B1 (AFB1). The mutagenic effect of AFB1 results from hepatic bioactivation to AFB1-exo-8,9-epoxide. This is in part catalysed by CYP3A5, an enzyme expressed polymorphically. We investigated the role of CYP3A5 polymorphisms in the formation of AFB1-exo-8,9-epoxide in The Gambia, a population exposed to high aflatoxin levels.

16. Spoilage patterns of skim and whole milks

Author

DEETH, HILTON C., KHUSNIATI, TATIK, DATTA, NIVEDITA, and WALLACE, ROBERT B.

Abstract

The reason for the reported difference in spoilage behaviour of skim and whole pasteurised milks was investigated. The rates of growth of psychrotrophic bacteria were not significantly different in the two milks and the bacterial types, all pseudomonads, present at spoilage were also similar. However, when representative spoilage organisms were cultured into freshly pasteurised skim and whole milks, skim milks exhibited predominantly bitter flavours while whole milk showed mostly sour flavours. The different spoilage behaviours can be largely explained by greater proteolysis in skim milk than in whole milk, caused by higher production of protease and greater susceptibility of the protein to protease attack. In addition, lipolysis in whole milk, caused by the substantial quantities of lipase produced by spoilage pseudomonads in this milk, also contributes to the different flavours produced during cold storage of these milk types.

17. Cytotoxic T-Lymphocyte Epitopes for HLA-B53 and Other HLA Types in the Malaria Vaccine Candidate Liver-Stage Antigen 3

Author

Aidoo, Michael, Lalvani, Ajit, Gilbert, Sarah C., Hu, Jiang Ting, Daubersies, Pierre, Hurt, Nicole, Whittle, Hilton C., Druihle, Pierre, and Hill, Adrian V. S.

Abstract

ABSTRACTThe development of an effective preerythrocytic vaccine againstPlasmodium falciparummalaria is likely to require inclusion of components from several preerythrocytic antigens. The association of HLA-B53 with resistance to severe malaria in West Africa provided evidence that HLA class I-restricted CD8+T-cell responses play a role in protective immunity in African children, supporting data from rodent models of malaria. Previously, a single epitope from liver-stage-specific antigen 1 (LSA-1) has been shown to be recognized by HLA-B53-specific cytotoxic T lymphocytes (CTL), but HLA-B53 epitopes were not found in four other antigens. In this study we measured CTL responses to peptides from the recently sequenced antigen liver-stage antigen 3 (LSA-3) and identified in it a new epitope restricted by HLA-B53. Several CTL epitopes restricted by other class I types were also identified within LSA-3 in studies in The Gambia and Tanzania. CTL were also identified to an additional P. falciparumantigen, exported protein 1 (Exp-1), the homologue of which is a protective antigen in a rodent model of malaria. These findings emphasize the diversity of P. falciparumantigens recognized by CD8+T cells in humans and support the inclusion of components from several antigens in new CTL-inducing vaccines against malaria.

18. Variations in the Seed Coat Colour of Adzuki Beans in the Aspects of Varieties, Harvest Years and Growing Locations, using Two-Dimensional Colour Mapping

Author

Kato, Jun, Meguro, Takashi, Suzuki, Masahisa M., and Deeth, Hilton C.

Abstract

AbstractThe variation in the seed coat colour of adzuki beans among varieties, harvest years and growing locations, using a two-dimensional colour mapping technique was investigated. It was found that the differences of the seed coat colour among varieties contributed to the variation of chroma (C*) values, while the differences of the seed coat colour among harvest years were associated with lightness (L*) values. The L*values for the seed coat colour increased when the temperature during the maturing period of adzuki beans was low, and decreased when the temperature was high. The difference in the seed coat colour among the samples from different growing locations was much larger in the L*values than the C*values for samples of the same variety. The seed coat colours of adzuki beans harvested in Hokkaido and China had significantly different C*values, and were easily discriminated by the colour mapping method. This study showed that the two-dimensional colour mapping was useful for evaluating the seed coat colour of adzuki beans, which varies among samples of different varieties, harvest years and growing locations.

20. Antigen-Specific Expansion of Cytotoxic T Lymphocytes in Acute Measles Virus Infection

Author

Mongkolsapaya, Juthathip, Jaye, Assan, Callan, Margaret F. C., Magnusen, Albert F., McMichael, Andrew J., and Whittle, Hilton C.

Abstract

ABSTRACTSkewing of the T-cell receptor repertoire of CD8+T cells has been shown in some persistent infections with viruses, such as human immunodeficiency virus, simian immunodeficiency virus, and Epstein-Barr virus. We have demonstrated that similar distortions also occur in nonpersistent measles virus infection. In addition, two of four children immunized with live, attenuated measles virus showed larger and more persistent CD8+T-cell expansions than their naturally infected counterparts. The expanded lymphocyte populations were monoclonal or oligoclonal and lysed target cells infected with recombinant vaccinia virus expressing measles virus protein. These results demonstrate that the expansions of CD8+T lymphocytes are antigen driven.

Abstract

Abstract: Interactions of the type ep → eXY are studied, where the component X of the hadronic final state contains two jets and is well separated in rapidity from a leading baryonic system Y. Analyses are performed of both resolved and direct photoproduction and of deep-inelastic scattering with photon virtualities in the range 7.5 < Q 2 < 80 GeV2. Cross sections are presented where Y has mass M Y < 1.6 GeV, the squared four-momentum transferred at the proton vertex satisfies |t| < 1 GeV2 and the two jets each have transverse momentum p Tjet > 5 GeV relative to the photon direction in the rest frame of X. Models based on a factorisable diffractive exchange with a gluon dominated structure, evolved to a scale set by the transverse momentum $$\hat p_T $$ of the outgoing partons from the hard interaction, give good descriptions of the data. Exclusive $$q\bar q$$ production, as calculated in perturbative QCD using the squared proton gluon density, represents at most a small fraction of the measured cross section. The compatibility of the data with a breaking of diffractive factorisation due to spectator interactions in resolved photoproduction is investigated.

Abstract

A search in the H1 experiment at HERA for scalar and vector leptoquarks, leptogluons and squarks coupling to first generation fermions is presented in a data sample corresponding to an integrated luminosity of 425 nb−1. For masses ranging up to ∼275 GeV, no significant evidence for the direct production of such particles is found in various possible decay channels. At high masses and beyond the centre of mass energy of 296 GeV a contact interaction analysis is used to further constrain the couplings and masses of new vector leptoquarks and to set lower limits on compositeness scales.

Abstract

Global properties of the hadronic final state in deep inelastic scattering events at HERA are investigated. The data are corrected for detector effects and are compared directly with QCD phenomenology. Energy flows in both the laboratory frame and the hadronic centre of mass system and energy-energy correlations in the laboratory frame are presented. Comparing various QCD models, the colour dipole model provides the only satisfactory description of the data. In the hadronic centre of mass system the momentum components of charged particles longitudinal and transverse to the virtual boson direction are measured and compared with lower energy lepton-nucleon scattering data as well as withe+e- dat from LEP.

Abstract

We present an experimental study of theep?e?+p andep?e?+X processes using data recorded by the H1 detector in 1993 at the electron-proton collider HERA. These processes are employed to measure the luminosity with an accuracy of 4.5 %. A subsample of theep?e?+X events in which the hard photon is detected at angles ??' = 0.45 mrad with respect to the incident electron direction is used to verify experimentally the size of radiative corrections to theep?eX inclusive cross section and to investigate the structure of the proton in theQ2 domain down to 2 GeV2, lower than previously attained at HERA.

27. Segmental colonic resection is an appropriate operation for short skip lesions due to Crohn's disease in the colon

Author

Allan, A., Andrews, H., Hilton, C. J., Keighley, M. R. B., Allan, R. N., and Alexander-Williams, J.

Abstract

Thirty-six patients have had a segmental colonic resection for Crohn's colitis between 1948 and 1984. There were 2 deaths caused by intraabdominal abscesses present before operation. There were no cases of anastomotic dehiscence in the 29 patients having segmental resection and immediate anastomosis. The reoperation rate at 10 years was 66% (95% confidence interval, 48–84%), the majority of reresections being for recurrent large bowel Crohn's disease.

29. Serologic status and measles attack rates among vaccinated and unvaccinated children in rural Senegal

Author

Abstract

During a measles vaccine trial in a rural area of Senegal, antibody status was examined within 10 days of exposure for 228 previously vaccinated and 313 unvaccinated children more than 12 months old who were exposed to measles at home. Thirty-six percent of the children developed clinical measles, the clinical diagnosis being confirmed for 135 of the 137 children from whom 2 blood samples were collected. Vaccine efficacy was 90 (95 confidence interval, 83 to 94). The hemagglutinin-inhibiting antibodies (HI) or plaque neutralizing antibodies (PN) assays were equally efficient in predicting susceptibility and protection against measles. Vaccinated children who had no detectable HI or PN antibodies at exposure had significant protection against measles compared with seronegative unvaccinated children (HI vaccine efficacy, 49 (95 confidence interval, 21 to 68); PN vaccine efficacy, 43 (95 confidence interval, 12 to 62)). The attack rate was high for children with a titer of 40 to 125 mIU) 67 (4 of 6) of those with a positive hemagglutinin-inhibiting antibody test and 36 (13 of 36) of those with a positive PN test developed measles. Attack rates among children with HI or PN titers above 125 mIU were 2 (6 of 295) and 3 (7 of 258), respectively. Because titers of ≥120 mIU have been found to offer little protection in another study, this antibody level may be the best screening value for assessing susceptibility and protection against measles. However, it should be noted that many seronegative vaccinated children are protected against measles infection.

30. Response to hepatitis B vaccine in a cohort of Gambian children

Abstract

In a cohort of 1000 Gambian children immunized with four doses of 10 μg of plasma-derived hepatitis B virus vaccine, 44 subjects (4.4) showed no response (10 mIU/ml; 6 subjects) or low specific antibody response (10 to 99 mIU/ml; 38 subjects) to hepatitis B surface antigen. Serologic indices, potentially correlated with low immunologic response, were investigated in sera obtained from these children and in sex-, age and village-matched controls who showed a normal response. The presence of circulating immune complexes in similar proportion of responding and poorly responding children together with a low prevalence of rheumatoid factors suggested that polyclonal B cell activation was not correlated with the subnormal humoral response. Concentrations of serum immunoglobulin (Ig) and IgG subclasses did not differ in the two groups. Some of the African prevalent Ig allotypes were determined, but no significant differences in the two groups were found. The humoral response to hepatitis B surface antigen did not correlate with the response to tetanus toxoid.

FORGIE, IAN M., CAMPBELL, HARRY, LLOYD-EVANS, NELLIE, LEINONEN, MAIJA, O'NEILL, KEVIN P., SAIKKU, PEKKA, WHITTLE, HILTON C., and GREENWOOD, BRIAN M.

Abstract

Approximately 500 children younger than 5 years old resident in 7 villages in a rural area of the Gambia were monitored closely for 1 year for episodes of acute lower respiratory tract infection (ALRI). Each episode was investigated with antigen detection techniques and antibody assays as well as culture for bacteria and viruses. A pathogen was identified in 76 (34.2) of 222 cases with clinical signs of ALRI and in 34 (42) of the 81 cases who, in addition, had radiologic evidence of ALRI. Evidence of infection with a bacterial pathogen, most commonly Streptococcus pneumoniaeor Haemophilus influenzae, was obtained in 32 (14.4) cases with clinical signs of ALRI (23.5 of those with radiologically proved pneumonia). Viral agents were cultured from 42 (19) of 221 cases but also from 14 (14.6) of 96 controls some of whom had minor symptoms of upper respiratory tract infection. In the absence of an outbreak of respiratory syncytial virus the viral agents recovered most often were influenza A and adenoviruses.

34. Mesothelioma in Connecticut, 1955-1977 Occupational and Geographic Associations

Author

Teta, Mary Jane, Lewinsohn, Hilton C., Meigs, J Wister, Vidone, Romeo A., Mowad, Linda Z., and Flannery, John T.

Abstract

All cases of malignant mesothelioma (201) and other primary malignant pleural tumors (19) reported to the Connecticut Tumor Registry from 1955 through 1977 were studied in an attempt to identify high-risk jobs, industries and geographic locations and to estimate the risk attributable to asbestos exposure in the workplace. Data were obtained from hospital records, death certificates and city directories for cases, case spouses and a random sample (604) of Connect/cut decedents (1955-1975). Three cases involved histories of work in asbestos products manufacture, but there was no evidence of residential risk in that geographic area. Relative risk (RR) for carpenters and cabinetmakers was 2.25 (p<. 05); for plumbers and pipefitters, 3.87 (p<.05); and for persons "ever employed" in the rubber industry, 5.08 (p<.01). Occupational exposure was indicated in 85 of the cases; attributable risk (A R) was 36. Risk increased with greater exposure and older age. AR was 81 in men aged 70 to 89 years at diagnosis. Reduction of unnecessary occupational asbestos exposure remains the highest public health priority.

35. Etiology of acute lower respiratory tract infections in Gambian children

Author

FORGIE, IAN M., O'NEILL, KEVIN P., LLOYD-EVANS, NELLIE, LEINONEN, MAIJA, CAMPBELL, HARRY, WHITTLE, HILTON C., and GREENWOOD, BRIAN M.

Abstract

Seventy-four children ages 1 to 9 years hospitalized because of severe pneumonia were investigated using blood cultures, lung aspirates, nasopharyngeal aspirates, serology and antigen detection procedures. A bacterial infection was identified in 57 (77), a viral infection was seen in 25 (34) and 18 (24) had mixed viralbacterial infections. The bacterial pathogens most frequently identified were Streptococcus pneumoniaeand Haemophilus influenzaefound in 61 and 15 of patients, respectively. The viral pathogen most frequently recovered was respiratory syncytial virus (12). Evidence of Chlamydia pneumoniaestrain TWAR and Mycoplasma pneumoniaeinfection was found in 12 and 4 of cases, respectively. Overall a potential pathogen was identified in 60 (81) children, with evidence of polymicrobial infection in 30 cases (40.5). The study provides information on the relative role of different infectious agents in the etiology of severe pneumonia in children in a developing country.

FORGIE, IAN M., O'NEILL, KEVIN P., LLOYD-EVANS, NELLIE, LEINONEN, MAIJA, CAMPBELL, HARRY, WHITTLE, HILTON C., and GREENWOOD, BRIAN M.

Abstract

Ninety infants less than 1 year of age with pneumonia and 43 control infants were investigated for viral and chlamydial infection with the use of culture and serology and for bacterial infection with the use of blood cultures, lung aspirates, antibody assays and antigen detection procedures. One or more potential pathogens were identified in 62 (69) cases with pneumonia and in 12 (28) controls. Infection by respiratory viruses was identified in 42 (49) cases and in 8 (19) controls. Respiratory syncytial virus was the commonest pathogen identified and was found in 32 cases (37). Bacterial infections were also common, being found in 27 (30) cases and 3 (7) controls, and predominantly involved Streptococcus pneumonias(20) or Haemophilus influenzae(11). Bacterial infections were associated with raised white blood cell counts and were identified more often by antigen detection procedures (68) than by culture of blood or lung aspirates (34) or by serology (33). Mixed viral-bacterial infections were identified in 13 cases (15). Infection with Chlamydia trachomatiswas diagnosed in 2 infants with acute lower respiratory tract infection and in 1 control infant.

Abstract

We report the results of phase II studies using a combination of ifosfamide, cis-platinum and bleomycin (BIP) in advanced and recurrent cervical cancer. Fifty-one patients have been studied. In 37 patients with disease not amenable to radical local therapy 27 objective responses (73%) were seen with 7 complete responses. Eleven of 14 patients (79%) with primary inoperable disease had at least a 50% reduction in tumour bulk prior to radical local radiotherapy. All patients experienced alopecia, nausea and vomiting. Other toxicity included myelosuppression, infection, reduction in renal function and disturbance of consciousness. There was no evidence that primary chemotherapy enhanced the acute toxic effects of pelvic radiotherapy. These data indicate that BIP is highly active in cervical cancer and can be used for effective palliation and cytoreduction in more than 70% of patients.

38. A Review of Medical Surveillance Records of Employees Exposed to Ethyleneamines

Author

Lewinsohn, Hilton C. and Ott, M. G.

Abstract

A review of medical surveillance records was undertaken for 197 personnel who had been assigned to an ethyleneamines (EA) production unit for one or more months between 1947 and 1983. Dispensary visit reports were examined relative to EA and other chemical exposures, medical records were reviewed for allergy and asthma histories, spirometry data were evaluated, and the mortality experience of these employees was studied relative to exposure status. AH findings were evaluated in reference to a comparable group of employees who did not work in plant areas where contact with EA was likely. Among 75 persons reporting EA exposures, 7 definite and 8 suspect cases of respiratory sensitization were identified. Similarly, there were S3 definite and 17 suspect cases of skin sensitization. Pulmonary function did not differ between study and referent groups and was unrelated to both EA assignment duration and skin or respiratory sensitization. There were no indications of increased mortality in the study group. Careful selection of employees for assignment to this unit may have occurred by plant physicians, who were aware of the potential sensitizing properties of EA.

Abstract

A search for squarks ofR-parity violating supersymmetry is performed inepcollisions at HERA using H1 1994e+data. Direct single production of squarks of each generation bye+-quark fusion via a Yukawa coupling λ′ is considered. All possibleR-parity violating decays and gauge decays of the squarks are taken into account. No significant deviation from the Standard Model predictions is found in the various multi-lepton and multi-jet final states studied and exclusion limits are derived. At 95% confidence level, the existence of first generation squarks is excluded for masses up to 240 GeV for coupling values λ′≳√4παem. The limits obtained are shown to be only weakly dependent on the free parameters of the Minimal Supersymmetric Standard Model. Stop squarks are excluded for masses up to 138 GeV for coupling λ′×cosθttoe+d pairs ≳0.1×√4παem, whereθtis the mass mixing angle.

Abstract

We present a new measurement of the total photoproduction cross section performed with the H1 detector at HERA. For an average centre of mass energy of 200 GeV a value of σtotλp=165±2±11µb has been obtained. A detailed analysis of the data in adequate kinematic regions enabled a decomposition of the total cross section in its elastic, single diffractive dissociation and remaining non-diffractive parts, based on safe assumptions on the double diffractive dissociation contribution.

Abstract

The double-differential inclusive di-jet cross section in photoproduction processes is measured with the H1 detector at HERA. The cross section is determined as a function of the average transverse jet energyETjets for ranges of the fractional energy??jets of the parton from the photon side. An effective leading order parton distribution in the photon is determined at large parton fractional energies for scale between 80 T2 < 1250 GeV2. The measurement is compatible with the logarithmic scale dependence that is predicted by perturbative QCD.

44. Role of orthotopic heart transplantation in the management of patients with recurrent ventricular tachyarrhythmias following myocardial infarction

Author

Bourke, J.P., Loaiza, A., Furniss, S., Parry, G., Hilton, C., Dark, J., and Forty, J.

Abstract

Objective To report the outcome of an intention to treat by heart transplantation strategy in two groups of patients after infarction, one with both left ventricular failure (LVF) and ventricular tachyarrhythmias (VTA) (group A) and the other with progressive LVF following antiarrhythmic surgery for VTA (group B). Patients and methods Group A comprised 17 consecutive patients for whom transplantation was considered the best primary non-pharmacological treatment; group B comprised five consecutive patients assessed and planned for transplantation after antiarrhythmic surgery. Results In group A, eight patients underwent transplantation and all survived the first 30 day period. At median follow up of 55 months (range 11 to 109) seven of this subgroup were still alive. Five patients died of recurrent VTA before transplantation, despite circulatory support. In the face of uncontrollable VTA, four of these underwent "high risk" antiarrhythmic surgery while awaiting transplantation: three died of LVF within 30 days and one was saved by heart transplantation two days after arrhythmia surgery. Mortality for the transplantation strategy in group A patients was 47% by intention to treat analysis. Quality of life in the eight actually transplanted, however, was good and only one died during median follow up of 56 months. The five patients in group B were accepted for transplantation for progressive LVF at a median of 21 months (range 12 to 28) after antiarrhythmic surgery. One died of LVF before transplantation, 22 months after initial surgery; another died of high output LVF three days after transplantation. Thus mortality of the intended strategy was 40%. The three transplanted patients are alive and well at 8-86 months. Conclusions Although the short and medium term outcome in category A or B patients who undergo transplantation is good, the overall success of the transplantation strategy in category A patients is limited by lack of donors in the short time frame in which they are required.

Abstract

Properties of the hadronic final state in photoproduction events with large transverse energy are studied at the electron-proton collider HERA. Distributions of the transverse energy, jets and underlying event energy are compared todata and QCD calculations. The comparisons show that theγpevents can be consistently described by QCD models including — in addition to the primary hard scattering process — interactions between the two beam remnants. The differential jet cross sectionsdσ/dETjetanddσ/dηjetare measured.

47. Segmental colonic resection is an appropriate operation for short skip lesions due to Crohn's disease in the colon

Author

Abstract

Thirty-six patients have had a segmental colonic resection for Crohn's colitis between 1948 and 1984. There were 2 deaths caused by intraabdominal abscesses present before operation. There were no cases of anastomotic dehiscence in the 29 patients having segmental resection and immediate anastomosis. The reoperation rate at 10 years was 66% (95% confidence interval, 48–84%), the majority of reresections being for recurrent large bowel Crohn's disease. The 10-year reoperation rates were higher than after subtotal colectomy and ileorectal anastomosis (53%; 95% confidence interval, 37–69%) performed in a comparable group of patients with colonie Crohn's disease. The difference did not achieve statistical significance. These findings suggest that when a patient with Crohn's disease has a short segment of diseased large bowel, a segmental resection is feasible and safe. Trente-six patients ont été opérés pour Maladie de Crohn entre 1948 et 1984 par colectomie segmentaire. Deux patients sont morts: ils avaient tous deux un abcès intra-abdominal préopératoire. Il n'y a eu aucune fistule anastomotique chez les 29 patients ayant eu une résection suivie immédiatement par une anastomose. Le taux de réopération à 10 ans était de 66% (intervalle de confiance à 95%: 48–84%), la plupart des résections complémentaires ayant été pratiquées pour les patients avec une Maladie de Crohn colique. Ce taux de ré-opération à 10 ans était plus élevé qu'après colectomie subtotale et anastomose iléo-rectale (53%; intervalle de confiance à 95%: 37–69%) effectuées chez un autre groupe de patients comparables. Cette différence n'était pas statistiquement significative. Ces données suggèrent que chez le patient ayant un court segment colique présentant une maladie de Crohn, la colectomie segmentaire est faisable et sure. Treinta y seis pacientes han sido sometidos a resección colónica por enfermedad de Crohn en el período 1948–1984. Ocurrieron 2 muertes causadas por abscesos abdominales presentes desde antes de la operacion. No se observaron casos de dehiscencia anastomótica entre los 29 pacientes en quienes se practicó resección segmentaria con anastomosis inmediata. La tasa de reoperación a los 10 años fue 66%; la mayoría de las reresecciones se debió a recurrencia de la enfermedad de Crohn en el colon. Las tasas de reoperación a 10 años fueron más altas que las observadas después de colectomía subtotal con anastomosis ileorrectal (53%) realizada en un grupo comparable de pacientes con enfermedad de Crohn, pero la diferencia no alcanzó significación estadística. Estos hallazgos sugieren que la resección segmentaria es factible y segura en el paciente que presenta un segmento corto de intestino afectado por enfermedad de Crohn.

48. Isolated lung transplantation for pulmonary fibrosis

Author

Conacher, I. D., Dark, J., Hilton, C. J., and Corris, P.

Abstract

The peri‐operative anaesthetic management of 11 patients with pulmonary fibrosis undergoing single‐lung transplantation is presented. Intra‐operative problems, the early postoperative phase of recovery and intensive care, and other incidents in which general anaesthesia was required for the management of complications, are featured. Results, both short‐ and long‐term, are mentioned. Major intra‐operative events that cause concern appear to be related to the severity of the presenting illness and the development of respiratory failure. Others have reported the development of intra‐operative cardiac failure. All cases were successfully managed operatively using conventional one‐lung anaesthesia, although resort to partial cardiopulmonary bypass may have been indicated in some. The indications and attitudes to utilising cardiopulmonary bypass in the evolution of techniques for facilitating single‐lung transplantation are reviewed.

49. Humber estuary — a case study

Author

Barr, R., Watson, P. G., Ashcroft, C. R., Barnett, B. E., and Hilton, C.

Abstract

This paper presents the results of an extensive and detailed survey conducted in 1985 on the biology, bacteriology and levels of heavy metals in subtidal sediments of the Humber estuary. The findings of the investigation are assessed with respect to environmental quality. Abundance and distribution patterns of the indicator species Capitella capitata, the numbers of faecal bacteria, and levels of heavy metals and organic matter are examined in relation to areas of sewage disposal. The possible effects of inputs from the Humber to the North Sea are discussed.
