ABSTRACT

Invasive fungal infections (IFIs) are the most frequent cause of morbidity and mortality in immunocompromised children. Voriconazole is the first-line antifungal choice in the treatment of IFIs like aspergillosis. Voriconazole pharmacokinetics vary widely among patients and voriconazole is metabolized mainly in the liver by the CYP2C19 enzyme, which is highly polymorphic. The CYP2C19*17 allele is characterized by the presence of four single nucleotide polymorphisms expressing an ultra-rapid enzyme phenotype with an accelerated voriconazole metabolism, is associated with low (sub-therapeutic) plasma levels in patients treated with the standard dose. Considering that in our center a high percentage of children have sub-therapeutic levels of voriconazole when treated with standard doses, we sought to determine the frequency of the CYP2C19*17 polymorphism (rs12248560) in a Chilean population and determine the association between voriconazole concentrations and the rs12248560 variant in immunocompromised children. First, we evaluated the frequency of the rs12248560 variant in a group of 232 healthy Chilean children, and we found that 180 children (77.6%) were non-carriers of the rs12248560 variant, 49 children (21.1%) were heterozygous carriers for rs12248560 variant and only 3 children (1.3%) were homozygous carriers for rs12248560 variant, obtaining an allelic frequency of 12% for variant in a Chilean population. To determine the association between voriconazole concentrations and the rs12248560 variant, we analyzed voriconazole plasma concentrations in a second group of 33 children treated with voriconazole. In these patients, carriers of the rs12248560 variant presented significantly lower voriconazole plasma concentrations than non-carriers (p = 0,011). In this study, we show the presence of the rs12248560 variant in a Chilean population and its accelerating effect on the pharmacokinetics of voriconazole in pediatric patients. From these data, it would be advisable to consider the variant of the patient prior to calculating the dosage of voriconazole.

ABSTRACT

Los linfomas de las glándulas salivales son una entidad poco frecuente, estimándose una incidencia del 5 por ciento. La localización más habitual es la glándula parótida, seguida de la submaxilary la sublingual. La mayoría de los linfomas parotídeos son linfomas no Hodgkin (LNH) y se consideran derivados del tejido linfoide asociado a mucosas (MALT). Infrecuentemente se han reportado estos casos y suelen ser subdiagnosticados por su presentación relativamente benigna, comportándose de forma localizada, de lento crecimiento, con varios años de evolución. Presentamos un caso clínico de linfoma tipo MALT de parótida de acuerdo a las características clínicas, histológicas e inmunohistoquímicas de este tumor. Además una revisión de la literatura de este caso.


Lymphomas of the salivary glands are a rare entity, with an estimated incidence of 5 percent. The most frequent location is parotid gland, followed by the submandibular and sublingual. The majority of parotid lymphomas are non-Hodgkin's lymphoma NHL and are considered derived from mucosa-associated lymphoid tissue (MALT). Infrequently these cases have been reported and are often underdiagnosed for their presentation is relatively benign, localized behaving, slow growing, with several years of evolution. We report a case of parotid MALT lymphoma according to the clinical, histological and immunohistochemical characteristics of this tumor. In addition, a literature review of this case.

ABSTRACT

Progesterone in hormone replacement therapy (HRT) preparations increases, while hysterectomy greatly reduces, the incidence of breast cancer. Cross-talk between the progesterone and growth factor signaling pathways occurs at multiple levels and this maybe a key factor in breast cancer survival and progression. To test this hypothesis, we characterized the effect of progesterone pre-treatment on the sensitization of the epidermal growth factor (EGF) signaling pathway to EGF in the breast cancer cell line ZR-75. For the first time in ZR-75 cells and in agreement with previous work using synthetic progestins, we demonstrate that pre-treatment with the natural ligand progesterone increases EGF receptor (EGFR) levels and subsequent ligand-dependent phosphorylation. Downstream we demonstrate that progesterone alone increases erk-1 + 2 phosphorylation, potentiates EGF-phosphorylated erk-1 + 2 and maintains these levels elevated for 24 h; over 20 h longer than in vehicle treated cells. Additionally, progesterone increased the levels of STAT5, another component of the EGF signaling cascade. Progesterone increased EGF mediated transcription of a c-fos promoter reporter and the nuclear localization of the native c-fos protein. Furthermore, progesterone and EGF both alone and in combination, significantly increase cell proliferation. Several results presented herein demonstrate the conformity between the action of the natural ligand progesterone with that of synthetic progestins such as MPA and R5020 and allows the postulation that the progestin/progesterone-dependent increase of EGF signaling provides a survival advantage to burgeoning cancer cells and may contribute to the breast cancer risk associated with endogenous progesterone and with progestin-containing HRT.

ABSTRACT

Mycoplasma pneumoniae es una causa frecuente de neumonía adquirida en la comunidad (NAC) en niños y adultos jóvenes, existiendo escasa información de su frecuencia en el adulto mayor. Se analizó la reacción de polimerasa en cadena (RPC) con dos pares de partidores, gen de la adhesina P1 y gen 16S rRNA, para la detección de M. pneumoniae en lavado faríngeo de 84 pacientes de 60-96 años con diagnóstico clínico de NAC, desde septiembre de 2002 hasta agosto de 2004. Los resultados de la RPC fueron comparados con los de la serología mediante inmunofluorescencia indirecta (IFI). Se detectó infección por M. pneumoniae mediante serología o RPC en 11 de 84 pacientes (13,1%). La serología fue positiva en 8 (72,7%) y la RPC en 7 (63,6%) muestras. La serología en la muestra de suero en fase aguda fue positiva en 5 de 11 pacientes (45,4%), en 4 de ellos por la presencia de IgM. En 4 pacientes con serología positiva la RPC fue negativa. En 3 pacientes con serología negativa la RPC fue positiva. Las dos RPC mostraron 100% de correlación y la sensibilidad fue la misma; no se detectaron muestras con efecto inhibitorio de la reacción. En conclusión, M. pneumoniae debería ser considerado en la etiología de la NAC en adultos mayores. La detección de este microorganismo debe basarse en el uso combinado de serología y RPC.

ABSTRACT

Mycoplasma pneumoniae is a common cause of community-acquired pneumonia (CAP) in children and young adults, but limited information about its prevalence in the elderly is available. The polymerase chain reaction (PCR) with primers targeting the cytadhesine P1 gene and the 16S rRNA gene was analyzed for detecting M. pneumoniae in throat washings of 84 patients, aged 60-96 years, with clinical diagnosis of CAP, from September 2002 through August 2004, in Santiago, Chile. PCR results were compared with serology performed by indirect immunofluorescence (IFI). Specimens from 11 of 84 patients (13.1%) were positive for M. pneumoniae by any test. The IFI test was positive in 8 (72.7%) patients and PCR in 7 (63.6%) cases. The acute phase sera allowed diagnosis of M. pneumoniae in 5 of 11 patients (45.4%), 4 of them showing an IgM response. PCR was negative in 4 patients with positive serology and 3 patients were positive only by PCR. The two PCR primers showed 100% correlation, and a similar sensitivity; no inhibitory specimens for PCR were detected. In conclusion, M. pneumoniae should be considered as a potential etiologic agent of CAP in the elderly. Its detection must be performed by a combination of PCR and serology.

ABSTRACT

It has been demostrated that the effect of inhaled medications is enhanced by spacer devices, but their sizes make them unpractical to carry around and they have additional cost. In order to test if a homemade cheap spacer is as effective as the commercial spacers, we tested a small plastic bag with a cardboard mouth piece. We recluted 17 patients over 16 years of age with an obstructive ventilatory limitation in spirometry with a significative response with 200 µg of albuterol. We randomized patients into two groups: one received the bronchodilator through a commercial spacer and the other through the homemade device. We observed that with the latter we obtained similar or better FEV1 and FVC increases. We conclude that the use of this cheap device can be used in patients with advantage over commercial ones.


Se ha demostrado que el depósito y efecto de los medicamentos administrados a través de los inhaladores presurizados mejora con el uso de espaciadores, pero la adherencia a estos accesorios no es buena por su costo y por su tamaño incómodo. Nuestro objetivo fue determinar si un sistema artesanal tipo reservorio, armado con una bolsa plástica unida a una boquilla de cartón, es efectivo como espaciador. Para esto, seleccionamos a 17 sujetos mayores de 16 años con espirometría con limitación ventilatoria obstructiva y respuesta espirométrica significativa a 200 µg de salbutamol en aerosol presurizado. Se les asignó aleatoriamente a dos grupos: uno con aerocámara y otro con bolsa. Con esta última se obtuvo aumento del VEF1 y de la CVF post broncodilatador de mayor magnitud que con la aerocámara, con diferencia estadística significativa. Nos parece que estos resultados validan al sistema de la bolsa como espaciador de aerosoles presurizados para el uso de los pacientes.

ABSTRACT

We report a 78 year old male with prostatism, that was subjected to a prostate biopsy. The pathological study showed a microvascular lymphocytic infiltration. Four months later, the patients presentd with reduced alertness, cough, dyspnea, fever and elevation of lactic dehydrogenase and erythrocyte sedimentation rate. Chest and abdominal CAT scans, bone marrow aspirate, protein electrophoresis and prostate specific antigen were normal. A re-evaluation of prostate biopsy showed an intravascular lymphoid infiltration, positive for CD45 and CD20, compatible with the diagnosis of intravascular lymphoma. Chemotherapy was started, but it was not tolerated by the patient and the response was partial. Therefore, treatment with monoclonal antibodies anti CD20 (Rituximab) was started. The tumor had a complete and prolonged (24 months) remission after the treatment.

ABSTRACT

APPs (aryloxyphenoxypropionates) and CHDs (cyclohexanediones) are two of the most important groups used post-emergence for the control of grass weeds. They inhibit the lipid synthesis in plants by interfering with the activity of the enzyme Acetyl-coenzyme A carboxylase (ACCase), acting at a meristematic level. The resistance patterns of the biotypes characterized seem to indicate the existence of different degrees of resistance. It is thus possible to identify biotypes presenting cross-resistance only to certain APPs, to APPs and CHDs, or only to CHDs. The objective of this work was to evaluate the cross-resistance to fenoxaprop-P-ethyl, fluazifop-P-butyl, propaquizafop, cyhalofop-butyl, haloxyfop-R-methyl, tralkoxydim and tepraloxydim in three species of Lolium (L. multiflorum, L. perenne, and L. rigidum) resistant to diclofop-methyl. The assays were conducted with petri-dishes in which, over increasing doses, fifty seeds per biotype and dose were located in each dish. Two weeks later, the following parameters were evaluated: germination (%), number of roots, radicle length, plumule length, and fresh weight reduction (%). Based on plumule length and fresh weight reduction (%), diclofop-methyl resistant biotypes showed cross-resistance to fenoxaprop-P-ethyl, fluazifop-P-butyl, cyhalofop-butyl, haloxyfop-R-methyl, but not to propaquizafop, tralkoxydim and tepraloxydim. The parameters germination (%), number of roots or root length did not show a good relation between the dose and its efficacy (curves of dose response) for any of the susceptible and resistant biotypes studied.

ABSTRACT

Análisis de la introducción de una nueva tecnología en Chile llamada "mamografía full digital o campo completo" para la detección precoz del cáncer de mama no palpable. Esta tecnología se ha desarrollado en Europa, Estados Unidos y en algunos países de Sud América. Se describen las ventajas de la mamografía full digital en la detección de microcalcificaciones comparada con la mamografía convencional. La mamografía digital en campo total permite que se visualice toda la glándula mamaria, desde la piel hasta la pared torácica (1, 2, 3). Entre julio del 2001 y julio del 2002 se estudiaron con mamografía full digital 3.176 pacientes. Se utilizó un mamógrafo digital de campo completo, General Electric Senographe 2000 D. Solo 48 casos disponían de una mamografía convencional reciente. En 10 de las 48 pacientes la mamografía digital detectó microcalcificaciones sospechosas, no visualizadas en mamografía convencional. Estos hallazgos modificaron en algunos casos la conducta de tratamiento en éstas pacientes (3-4).


Introduction of a new technology called "full field digital mammography" (FFDM) for the detection of non palpables breast cancers. The GE Senographe 2000 D is the world`s first all digital mammography system and is installed in Europe, USA and some countries of LatinAmerica. Description of the advantages of full field digital mammography in comparison to conventional Film-Screen Mammography. (FSM) in the study and detection of microcalcifications. Full field digital mammography gives better visibility of the breast, particularly near the skin line , the chest wall and in women with dense breast tissue. Between july 2001 and july 2002, 3.176 patients were studied with full digital mammography with a GE Senographe 2000 D. Only 48 cases had a recently conventional mammography and in 10 of the 48 cases the full digital mammography detected suspicious microcalcifications not seen in conventional mammography. This results changed the patient treatment in some cases.

ABSTRACT

In 179 patients subjected to 186 renal tranplants, 30 renal biopsies were performed due to the presence of a proteinuria over 3.5 g/24 h or due to a reduction in glomerular filtration rate. Six of these biopsies, coming from 5 patients, disclosed morphological alterations compatible with focal segmental glomerulosclerosis. Five of these were due to recurrence of the primary disease (in 4 patients) and in all, massive proteinuria appeared from 1 to 23 days after transplantation. Two patients with three transplants evolved to renal failure and required dialysis in a period 12 months as a mean. The third patient, developed a nephrotic syndrome without renal failure and died 14 months after the renal transplant due to stroke. In the fourth patient, the nephrotic syndrome disappeared 38 days after the transplant and remained with minimal proteinuria until his last follow up visit two years later. The primary disease of the fifth patient is unknown, the nephrotic syndrome appeared 68 months after the transplant and remitted spontaneously in 2 months. The renal biopsy showed focal and segmental lesions with partial effacement of epithelial foot processes. It is concluded that focal segmental glomerulosclerosis recurrence in renal transplant occurs with aerly massive proteinuria and frequently leads to renal failure and graft loss in no more than two years

ABSTRACT

Se presenta la experiencia del Consultorio de Patología Vulvar del Hospital Clínico de la Universidad de Chile, sobre el carcinoma escamoso vulvar invasor superficial, durante el período comprendido entre enero de 1967 y abril de 1992. Se estudiaron ocho pacientes, cuya edad promedio era de 57,1 años. El diagnóstico se confirmó histopatológicamente en todos los casos. Tres de las enfermas fueron sometidas a vulvectomía total simple; a otras 3 se les practicó vulvectomía total con linfadenectomía inguinocrural bilateral, en forma clásica, mientras que las dos restantes fueron tratadas mediante vulvectomía simple en un caso y parcial en otra y en ambas linfadenectomía inguinal bilateral por incisiones separadas. El estudio histopatológico de la biopsia reveló en el 50 por ciento de los casos, concomitancia de carcinoma intraepitelial en la vecindad del carcinoma microinvasor. El seguimiento de nuestras pacientes osciló entre 2 y 25 años, con un promedio de 10,5 años. Se constató recidiva de carcinoma intraepitelial de la vulva en una de ellas, a los 2 años 8 meses después de haber sido sometida a vulvectomía total con linfadenectomía inguinocrural bilateral y luego a los 8 años. En otra paciente, se comprobó un carcinoma anal, 20 años después de la vulvectomía
