Anemia en paciente anciano, ¿podemos estar tranquilos? / Anaemia in an elderly patient: can we be complacent?

Presentamos el caso de un paciente de 70 años con un descenso progresivo de hemoglobina en analíticas seriadas. Tras un estudio riguroso se llega a un diagnóstico realmente poco frecuente: anemia hemolítica autoinmunitaria secundaria a carcinoma broncopulmonar (AU)

We present the case of a 70 year-old patient with a gradual decreasing haemoglobin. After a careful study, a very rare diagnosis was made: autoimmune haemolytic anaemia secondary to lung neoplasms (AU)

Installation of a water disinfection system in a Mexico City hospital.

With a view to evaluating a small-scale water disinfection system based on production and application of oxidizing gases, the level of equivalent residual chlorine and the degree of contamination by fecal and total coliform bacteria was assessed at various points in the drinking water system of a Mexico City hospital before and after installation of the disinfection equipment. Tests done in May and June 1989, prior to installation of the equipment, showed that residual chlorine concentrations were lower than the national standard in most of the samples and that a sizable portion of these samples were also contaminated with fecal and total coliform concentrations exceeding national standards. After installation of the disinfection system at the main inflow to the hospital's drinking water supply in August 1989, the equivalent residual chlorine concentrations were found adequate and no coliform bacteria were detected. These results indicate that the oxidant mixture generated by the newly installed system was effectively disinfecting the water.

[The evaluation of the integral water treatment system of a general hospital in Mexico City]. / Evaluación del sistema integral para tratamiento del agua en un hospital general de la Ciudad de México.

The Mexican Health Office (SSA) promotes the use and progeny of the appropriate technology for the bacteriological quality evaluation and disinfect the water by means of the in situ progeny of the clorus and ozonus gases when needed, for the human consumption in suburban and rural communities. The clorus water disinfecting conventional methods by many reasons are useless, even in urbanized cities. CEDAT has built and design a group of apparatus, called: "Water treatment whole equipment for small communities", and it's build up by: Membrane Filter, Double Chamber Incubator, ultraviolet Light Sterilizer and a clorus and ozonus progenic gas electrolytic cell with CA and CD power box and a Venturi Tube. The electrolytic cell raw material is the sodium chlorine (salt) water mixed. The evaluation of these equipment was made at the Manuel Gea González Medical Doctor General Hospital. During 38 days there was a daily measure of chlorine sewage in six different parts of the hospital. It was used the cellulose membrane filter technic with a 0.45 mm porus and a sowing in M-Endo and M-FC Broth cultivation was in a 37 and 44 centigrade incubation. The first 10 days chlorine sewage was found, the last 28 weren't measurable. Total coliforms in 23 of 42, 7 days samples and excrement coliforms in 5 of 18, 3 days samples, were developed during the 38 days period. The electrolytic cell was settled for the water gas measure up in its way to the reservoir. Afterwards chlorine sewage was measured from 0.2 mg/l to 1 mg/l in all the sample parts. No germ kind was discovered during the 10 days sampling.(ABSTRACT TRUNCATED AT 250 WORDS)

[Epidemic parotitis and Reiter's syndrome]. / Parotiditis epidémica y síndrome de Reiter.

A case of epidemic parotiditis in an adult male affected by Reiter's syndrome, is presented. The symptoms of Reiter's syndrome lasting 3 months after the recovery from epidemic parotiditis. Although descriptions of Reiter's syndrome of viral origin (adenovirus or hepatitis virus) exist, we have not found references of a relation to epidemic parotiditis. The diagnosis criteria of this syndrome is discussed, as well as the study of the epidemic parotiditis. We review the existing theories in order to justify the multiple etiology of this interesting syndrome.

[Antibiotic sensitivity, serology and typing by pyocine in 154 cultures of Pseudomonas aeruginosa (author's transl)]. / Sensibilidad antibiótica, serología y piocinotipia de 154 aislamientos clínicos de Pseudomonas aeruginosa.

Pseudomonas infections continue to be an important problem in the hospital environment. Serious infections are always invariably associated with severe underlying conditions or with diminished host resistance. The increasingly resistance of strains and hospital epidemics favour the organism prevalence. During 1978, Pseudomonas aeruginosa was isolated in 154 cultures from a variety of biological samples in the hospital. Tests of biochemical identification, serological typing, and typing by pyocine production were carried out. Susceptibility to aminoglycosides and beta-lactamic antibiotics was also tested. Serological study demonstrated a higher incidence of 4 and 11 serotypes; 69.4 percent corresponded to type I when typing by pyocine production was carried out. No relationship between serotypes and pyocine-types has been found. Ticarcillin showed a greater activity than carbenicillin (minimal inhibitory concentration less than or equal to 16 micrograms/ml). Amikacin, tobramicin, sisomicin and gentamicin inhibited 83.7 percent, 73.6 percent, 70.7 percent and 69.4 percent of the isolated strains, respectively.
