Abstract

The control of outdoor thermal comfort is an important task to ensure the quality of urban public spaces (UPS). The thermal optimization of UPS is vital for the urban design and planning process as it contributes to the quality of life in cities. The thermal comfort in UPS depends on climate and several urban components. In this research the influence of vegetation on urban air temperature is analyzed. The investigation is focused on the summer season, considering three urban areas located in the city of Rosario. The 1st area has the highest building density, whereas the 3rd area has the lowest. Urban air temperatures were calculated with the Urban Weather Generator (UWG) software. A maximum vegetation scenario was evaluated in each area and the effect of the increase of vegetation on air temperatures was calculated. Results show a temperature decrease of 0,4°C during daytime in the 2nd area. In the 3rd área, greater decreases in atmospheric temperatures were achieved, obtaining a temperature difference of 1°C. In the 1st area the vegetation increase generated a decrease of 0,1°C. We can infer that the increment in the latent heat flux due to vegetation is not sufficient to counteract the urban temperature rise due to the other urban sensible heat fluxes. Nevertheless, the latent heat balance in UWG is computed in a simplified manner and its positive contribution on the urban heat island intensity could be underestimated. The influence of urban characteristics (such as albedo and pavement thickness), envelope and energy efficiency of buildings on the urban heat island effect will be investigated in future research; and using different microclimatic simulation softwares that have more sensitivity to the parameters.

13. [Bacterial meningitis and CSF cytokines]

Author

Ticca, F., Lancella, L., Mastroianni, Claudio Maria, Comparcola, D., Graziani, M. C., Nicolosi, L., Rivosecchi, M. R., Catania, S., and Vullo, Vincenzo

Abstract

Aim of study is the determination of concentrations of two important cytokines: TNF alfa and IL8 in children with bacterial meningitis to establish a correlation between infection, CSF concentration of cytokines and neurological sequelae. TNF alfa and IL8 concentrations in CSF have been measured by quantitative immunometric enzyme assay during the course of the disease. In the purulent meningitis we observed that CSF concentrations of these cytokines decreased to undectable values 24 to 48 hours after beginning of the antibiotic therapy. Conversely, in the 3 patients with mycobacterial meningitis (TBM) the concentrations of IL8 were higher for a longer period, being detectable in the CSF between 4 and 8 weeks after the beginning of the specific treatment. We found no significant differences of the values of IL8 in children with neurological sequelae compared with children without sequelae.

40. The role of transanal endorectal pull-through in the treatment of Hirschsprung's disease – a multicenter experience.

Abstract

The transanal approach (TAA) is a new technique for surgery of Hirschsprung's disease (HD) that was introduced by de la Torre in 1998. The purpose of this multicenter study, including experience from three Austrian and one Italian departments of peadiatric surgery, was to evaluate the role of this approach in HD in 18 children aged 1–72 months. In 14 children the TAA only was performed; in 3 an additional laparoscopy was performed and in 1 conversion to a laparotomy was necessary. One complication (abscess) occurred after laparoscopic-assisted pull-through. The postoperative recovery was rapid, no severe long-term problems were observed. The transanal pull-through technique is generally possible in most classic cases of HD with extension of the disease to the sigmoid colon. If necessary, it can be combined with laparoscopy. Our preliminary results show that the technique is safe, less invasive, and gives excellent cosmetic results, and allows rapid recovery. Long-term results are still pending. [ABSTRACT FROM AUTHOR]

43. Conservative treatment of corrosive esophageal strictures: A comparative study of endoscopic dilatations and esophageal stenting.

Author

Peppo, F., Rivosecchi, M., Federici, G., Matarazzo, E., Ponticelli, A., Schingo, P., and Dall'Oglio, L.

Abstract

From 1982 to 1990, 222 children (mean age 2.5 years, range 1-11 years) were admitted to Bambino Gesu' Children's Hospital for suspected caustic ingestion. In 126 cases (56.7%) esophageal injuries were evidenced on endoscopy, which was always performed within 24 h of the injestion. Eighteen children (8.1%) developed an esophageal stricture; 4 of these were treated surgically and the remaining 14 were included in two different protocols of conservative treatment: up to 1987, 7 patients (group 1) underwent periodic esophageal dilatations; from 1988 to 1990, 7 (group 2) were treated by esophageal stenting. In group 1, a mean of 25.1 ± 17.8 months and 19.3 ± 15.8 dilatations were necessary for the stenosis to heal completely. In group 2, disappearance of the stricture was achieved within 12.8 ± 9 months with a mean of 9.4 ± 11 dilatations. Esophageal stenting appeared to reduce by half both the duration of treatment and the number of dilatations required to obtain complete healing of corrosive stenoses. Moreover, the scars softened after stent placement, allowing safer dilatation of recurrent strictures. [ABSTRACT FROM AUTHOR]
