Treatment optimization of patients with epithelial coccygeal passage complicated by an abscess

Background: Despite the wide variety of epithelial coccygeal passage treatment methods, the choice of the type of surgery is still an issue to be discussed. It is due to the heterogeneity of the clinical material, the variety of pathological processes and development of the pathology. In spite of the absence of serious complications in most cases, it causes a significant deterioration of life quality and reduction of work capacity in patients of the most active age group.Objective: Improvement of the treatment results of patients with epithelial coccygeal passage complicated by an abscess by means of vacuum therapy of a sutured postoperative wound (Russian Patent 2764499 date 07.04.2021).Material and methods: The study included 59 patients: 19 people in the main group, who underwent surgical treatment of the epithelial coccygeal passage complicated by an abscess, using vacuum therapy according to the proposed method. A retrospective analysis of the medical histories of patients who underwent surgical treatment of the epithelial coccygeal passage complicated by an abscess has been carried out by means of the traditional method of wound closure with drainage. These patients were included in the control group of 40 people.Results: In the control group purulent-inflammatory complications were recorded in 4 (10%) patients. Out of 19 people of the main group operated on according to the method proposed by us, purulent-septic complications were not recorded in any of the patients. Wound bandaging has been performed 71 times in 19 patients of the main group, and 454 times in 40 patients of the control group. For 19 patients of the main group the duration of the antibiotic therapy lasted 96 days, for 40 patients of the control group - 306 days. The average number of bed-days for patients of the control group was 10.63, in the main group - 7.56.Conclusion: The use of the proposed method of surgical treatment of epithelial coccygeal passage complicated by an abscess, by means of vacuum therapy at all stages of treatment, made it possible to improve treatment results in patients of the main group

POSTOPERATIVE WOUND INFECTION IMPACT ON LONG TERM ONCOLOGICAL OUTCOMES IN RECTAL CANCER PATIENTS

Background. Now there are heteropolar opinions on influence of postoperative purulent septic complications on rectal cancer patients on the long term oncological results.Objective. Assess influence of these complications following laparotomy and perineal wounds after operations for rectal cancer on the long term oncological results.Methods. We performed retrospective cohort research of 338 patients undergone scheduled radical operations for middle ampullar and lower ampullar rectal cancer T1-4N0-2M0 from January, 2003 to December, 2011. Patients were distributed in two groups: with suppuration of postoperative wounds and/or abscess of the abdominal cavity (n = 44–13%) and without purulent septic complications (n = 294).Results. The logit regression analysis has shown that suppuration of laparotomy wounds and/or abscess of the abdominal cavity is one of the independent risk factors of a systemic recurrence. For development of a local recurrence purulent septic complications were not risk factors. The five-year overall and cancer specific survival in compared groups demonstrated statistically significant distinction. The overall survival in the main group – 47%, in the control one – 67.2% (Wilcoxon’s criterion р = 0.10, Cox-Mentela’s criterion р = 0.02, log rank criterion р = 0.03). Cancer specific survival was 43.5% and 70.1% respectively (Wilcoxon’s criterion p = 0.01, Cox-Mentela’s criterion p = 0.005, log rank criterion p = 0.009). The five-year recurrence free survival in the compared groups was similar 50.6 and 69% respectively (Wilcoxon’s criterion p = 0.25, Cox-Mentela’s criterion p= 0.12, log rank criterion p = 0.12).Conclusion. Purulent septic complications of postoperative wounds in patients with rectal cancer have impact on long term results: they are independent risk factor for systemic recurrence development and decrease total and cancer specific survival rate

Way of the early combined forecasting of development of suppurations of postoperative wounds in a preclinical phase

The new way of forecasting of the beginning suppuration of postoperative wounds in a preclinical phase is offered. Its efficiency is studied in two comparable groups the coloproctologic of patients. Use of a new way of diagnostics authentically allows to prevent transformation of infectious process in clinically visible suppuration

Choice way of closing a wound in the abdominal wall complex surgical treatment of peritonitis prevalence

It studied 764 patients with widespread peritonitis shows the benefits of treatment relaparotomy-programmed with the closing of the surgical wound with removable draining musculoaponeurotic seams (RDMAS). In the case of intra-abdominal pressure normalization performed laparotomic closing the wound using RDMAS, and at its persistent increase -only skin sutures. This proved a significant decrease in mortality. For large defects of the abdominal wall, in the case where the conventional surgical wound closure of sutures is impossible, it is permissible use of fabric tensor, and free shaded plastic skin flaps

Ultrasound efficiency in relation to sodium hypochlorite and filtration adsorption in microbial elimination in a water treatment plant

Processes like ultrasound, chlorination and filtration-adsorption were compared to eliminate microorganisms and to adjust established parameters of public drinking water. A mini water treatment plant (WTP-CB), in pilot scale, was projected and built to evaluate each process influence as: decontamination, coagulation-flocculation, sedimentation and filtration. Total and fecal coliforms, Escherichia coli and heterotrophic bacteria and physic/chemical parameters were quantified from water. Ultrasound, chlorination and filtration-adsorption were efficient to inactivate and/or eliminate bacteria. Ultrasound decontamination in addition to coagulation-flocculation, sedimentation and filtration, could be considered as an alternative treatment water solution where prechlorination, coagulation-flocculation, sedimentation and filtration were used. The chlorination itself was efficient in inactivating bacteria despite of the coagulation-flocculation process; however, in the absence of the coagulation process, the resultant water did not achieve the established parameters. The filtration-adsorption was an important process to eliminate bacteria, showing that the filter retained particles, suspended solids, besides chemical substances and microorganisms.<br>Comparou-se diferentes processos: ultra-som, cloração e filtração/adsorção para eliminação de microrganismos e adequação de outros parâmetros exigidos para água de abastecimento público. Para avaliar a influência de cada processo: desinfecção, coagulação/floculação, decantação e filtração foi projetada e construída uma Estação de Tratamento de Água (ETA-CB) em escala piloto. Foram avaliados coliformes, bactérias heterotróficas e parâmetros físico/químicos. Ondas ultra-sônicas, cloração e filtração/adsorção mostraram-se eficientes na inativação e/ou eliminação de bactérias. O processo de desinfecção com ultra-som juntamente com a coagulação/floculação, decantação e filtração, pode ser considerado como um tratamento alternativo do processo tradicional onde utiliza-se pré-cloração, coagulação/floculação, decantação e filtração. A cloração mostrou-se eficiente na inativação de bactérias, independente da aplicação do processo de coagulação/floculação, porém na ausência desse processo à água resultante não atingiu a especificação de potabilidade. A filtração/adsorção mostrou-se importante na eliminação de bactérias, evidenciando que o filtro retém partículas, sólidos suspensos, substâncias químicas e microrganismos

Nest structure and colony cycle of the Allegheny mound ant, Formica exsectoides Forel (Hymenoptera: Formicidae)

The nest structure and colony cycle of a population of Allegheny mound ants, Formica exsectoides , were examined in central Michigan. The dispersion pattern of mounds was random. Nest structure and presence of brood were primarily determined by excavation of twenty-three nests over three intervals from June through September. Additional excavations of five nests in 1990 and ten nests in 1991 provided further details on nest structure and colony cycle. Most galleries occurred within the mound and upper 30 cm of soil, but some activity reached depths of 100 to 270 cm. Depth of nests showed little correlation with external measurements of height and diameter. Immature stages were recovered from two strata: the upper 20 cm of nest and mound and the lowest nest depths. Alate sexual forms were found in or near the mound in July, and numerous dealate queens were collected in September from peripheral galleries near the soil surface.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/45979/1/40_2005_Article_BF01240623.pd
