Análisis de situación de tuberculosis en el Área Programática del Hospital General de Agudos Parmenio Piñero: Año 2017 / Analysis of tuberculosis situation at Programmatic Area of the Acute General Hospital Parmenio Piñero: 2017

El área programática del Hospital Parmenio Piñero (AP-HGAPP) se localiza en el sur de la ciudad, e incluye parte de las comunas 7, 8, 9, 10, 6 y 4. Según datos provenientes del Censo 20105, se registraron 324.179 personas viviendo en este territorio, con un porcentaje de población con Necesidades Básicas Insatisfechas de 10,4% (superior al valor promedio de CABA de 7%). Se presenta en este informe un análisis de situación de tuberculosis, tomando como eje el territorio y la población a cargo del hospital y sus centros de salud y acción comunitaria. (AU)

Acid-base equilibria in aqueous solution of cis-bis(trimethylphosphine)platinum(II) dinitrate at 25 degrees C, 0.2 M ionic strength. A potentiometric study.

Acid-base equilibria in aqueous solutions of cis-bis(trimethylphosphine)platinum(II) dinitrate at 25 degrees C, 0.2 M ionic strength (KNO(3)), have been investigated by potentiometry with a glass electrode. The procedure consisted of multiple addition of the investigated analyte to a supporting electrolyte solution ("multiple sample addition") and subsequent titration with strong base. For the treatment of potentiometric multiple sample addition data, a new linearization procedure, suitable for an acid dissociation equilibrium whose product dimerizes, has been devised and tested. The potentiometric results have been interpreted with the support of NMR data. By dissociation of the first acidic function of the solute diaquo cation, cis-[(PMe(3))(2)Pt(OH(2))(2)](2+), a dimeric ampholite, cis-[(PMe(3))(2)Pt(mu-OH)](2)(2+), is quantitatively formed which, in turn, can be converted into the di-hydroxo derivative cis-(PMe(3))(2)Pt(OH)(2). The two acid dissociation steps involving two molecules of solute and condensation of ampholyte have pK(a1(c)) = 3.89 and pK(a2(c)) = 22.17.

[Combined surgical and radiotherapy treatment in endometrial cancer]. / Il trattamento combinato chirurgico e radioterapico del cancro dell'endometrio.

Early stage endometrial carcinoma is usually treated by surgery and radiotherapy if there is a substantial risk of recurrence. The aim of this study was to evaluate early and late toxicity, to determine the sites of recurrence and the prognostic factors which were statistically correlated with survival in patients who were treated with surgery plus external beam radiotherapy. MATERIALS AND METHODS. We have carried out a retrospective analysis of the records of 87 patients treated with hysterectomy plus external beam pelvic radiotherapy (50 Gy/28 Fractions), at the Radiotherapy Division of the CRO Aviano PN Italy, between 1985 and 1990. The median length of follow-up was 32.42 months. RESULTS. The treatment was well tolerated. The median time to recurrence was 6.56 months. There were 4.7% local, 5.8% distant and 3.5% local plus distant recurrences. As of May 1993 83.2% of the patients were still alive. All deaths occurred within two years from the beginning of treatment. The prognostic factors which were significantly correlated with survival were the stage of the disease (p = 0.0479), depth of myometrial invasion (p = 0.0429), age greater than 64 years (p = 0.0357) and performance status < = 80 at diagnosis (p = 0.0002). CONCLUSIONS. Our study confirms that post operative external beam pelvic RT is well tolerated and effective in achieving a good locoregional control. All the factors investigated were prognostic for survival, except histological grade, lymph node involvement and RT dose.

Postoperative radiotherapy in locally advanced head and neck cancer.

This retrospective study was conducted on 255 consecutive patients with locally advanced squamous-cell carcinoma of the oral cavity, oropharynx, larynx or hypopharynx, treated at the Radiotherapy Department of Pordenone General Hospital between January 1975 and December 1985. All patients underwent radical surgery followed, after an interval ranging from 10 days to 2.9 months, by radiotherapy given either through a 6 MeV linear accelerator or a cobalt-60 unit. Field extension and dose delivered were comparable in relation to stage and involvement of the surgical resection margins. The aims of the study were to evaluate the survival rate and to analyze the clinical parameters which can influence the disease-free survival. The adjusted overall 5-year survival rate was 71%; stage, performance status at diagnosis, and site of the primary tumor were significant factors in determining patient prognosis, whereas infiltration of resection margins was not significant in determining loco-regional control of disease. Seventy-five patients relapsed and 67 died of cancer-related diseases whereas death in 52 patients was not related to the head and neck cancer. The combined modality treatment consisting of surgery followed by radiotherapy was well tolerated and proved to be effective in the treatment of locally advanced head and neck tumors.

Estramustine phosphate (Estracyt) treatment of T3-T4 prostatic carcinoma.

From September, 1978, to November, 1980, 69 consecutive patients with locally advanced (T3-T4) prostatic adenocarcinoma, with or without distant metastases, were treated with oral estramustine phosphate. Dosage was 15 mg/kg/day for 2 months, followed by 5 mg/kg/day until progression. In the 48 evaluable patients with progressive disease that entry in the study, 1 complete response, 7 partial responses, 31 disease stabilizations, and 9 progressions were encountered (81.2% NPCP response rate). Karnofsky performance status equal to or less than 50 was predictive of poor response to estramustine phosphate. In the 10 evaluable patients with stabilized disease at entry in the study after orchiectomy, 2 complete responses, 4 partial responses, 3 disease stabilization, and 1 progression were noted. The major side effects observed were gynecomastia, nausea, and vomiting.
