Siliconoma cervical tras mastectomía y reconstrucción con prótesis / No disponible

Los implantes de gel de silicona han sido desde su aparición en 1960 el material protésico más utilizado en la reconstrucción mamaria postmastectomía, así como en la mamoplastia de aumento. Una de las complicaciones más frecuentemente reconocida es su ruptura, cuya incidencia se estima entre un 0,2 y un 4% en relación con la edad del implante. Una consecuencia de la rotura de la prótesis es la migración de la silicona a los ganglios linfáticos y la aparición de siliconomas en los territorios de drenaje de la mama. En la literatura son muchos los casos descritos de linfadenopatía axilar tras la rotura de prótesis mamarias. Se presenta un caso de siliconoma en la región cervical en una paciente con reconstrucción postmastectomía(AU)

Silicone breast implants are widely been used since 1960. They are the material prosthetic choice for a great number of implant designs both postmastectomy reconstruction, as well as breast augmentation. Prosthesis rupture is one of the most frequently known complication, whose incidence is estimated between 0.2 and 4%, increasing with the age of the implant. One consequence of implant rupture is silicone migration to lymphatic nodes and the formation of siliconomas in the lymphatic drainage of the breast. The literature offers many cases of axillary lymphadenopathy after ruptured breasts implants. We present the case of a siliconoma in the cervical region after postmastectomy implant placement(AU)

Linfangiosarcoma en paciente mastectomizada (síndrome de Stewart-Treves) / No disponible

El linfangiosarcoma postmastectomía (LPM) es un tumorvascular muy infrecuente y agresivo, que asienta habitualmenteen brazos portadores de un linfedema de larga evolución,tras una mastectomía radical por cáncer. Su incidencia es del0,45% en pacientes que sobreviven 5 años tras la mastectomíaradical. La etiología de estos tumores es aún completamentedesconocida. En la actualidad no existe un tratamientoestandarizado. Las opciones terapéuticas incluyen la exéresisquirúrgica, amputación de la extremidad afectada, desarticulación,radioterapia y quimioterapia. El pronóstico es malo. Lasupervivencia tras el diagnóstico oscila entre 8 y 15 meses.Presentamos el caso de una paciente con linfangiosarcomapostmastectomía radical y radioterapía(AU)

Lymphangiosarcoma postmastectomy is an uncommonvascular tumor, arising in the area of chronically lymphoedematousextremity, after radical mastectomy and radiotherapyin patients with breast cancer. It shows an incidence of 0,45%among patients that survive more than five years after radicalmastectomy. The etiology of this enigmatic tumor is not yetcompletely understood. There is no standard treatment. Thetreatment options include radical ablative surgery, amputation,radiation therapy and chemotherapy. The prognosis is poor.Survival after diagnosis ranged from 8 to 15 months. We reportthe case of patients with LPM and RT(AU)

[Is mucinous colorectal adenocarcinoma a distinct entity?]. / Es el adenocarcinoma colorrectal mucinoso una entidad diferente?

INTRODUCTION: Several publications have demonstrated that mucinous carcinomas of the colon and rectum are associated with certain clinicopathological and genetic peculiarities that distinguish them from non-mucinous carcinomas. The principal aim of this study was to evaluate whether the biological behavior of mucinous carcinomas differs from that of intestinal carcinomas in patients undergoing surgery for colorectal cancer. PATIENTS: Between January 1993 and December 2000, 215 patients. underwent surgery in our hospital for colorectal cancer. The patients were divided into two groups according to histological type: tumors were intestinal in 169 patients (82%) and mucinous in 36 (17.6%). Patients undergoing non-resective surgery and those with tumors of other histological types (n = 10) were excluded. RESULTS: The percentage of patients aged less than 50 years in the group with mucinous carcinoma was 19% (7/36) compared with 4% (7/169) in the non-mucinous group (p = 0.001). Regarding presenting symptoms, anemia was more frequent in patients with mucinous carcinoma (18.2% [n = 6] vs 5.7% [n = 8]) and a change in bowel habits was less frequent (15% [n = 5] vs 34.3% [n = 48]; p < 0.05). A total of 63.9% of mucinous carcinomas (n = 23) were located in the proximal colon (cecum, ascending and transverse colon) compared with 21.3% (n = 36) of non-mucinous carcinomas (p < 0.001). Surgical intention was palliative in 41.7% (n = 23.7) of mucinous carcinomas and in 23.7% (n = 40) of non-mucinous carcinomas (p < 0.05). The mean tumoral size was 6.2 2.5 cm in mucinous carcinomas and 4.7 2 in non-mucinous carcinomas (p = 0.001). Patients with mucinous carcinoma presented a higher percentage of nodal and distant metastases and a lower percentage of early stage tumors (p < 0.05). However, no differences were found in survival between the two histological types. CONCLUSION: Mucinous tumors were more frequently located in the right colon and in patients less than 50 years old and were more likely to be in more advanced stages than non-mucinous tumors but no differences were found in survival according to tumor type.

Possible theoretical treatments for transfer processes through membranes.

The transfer process of salicylic acid through a cellophane membrane is studied. The active component is formulated as a semisolid emulsion (O/W) for external local application. Different theoretical mathematical models are applicable to the experimental data obtained in order to find the mathematical expressions which define the transfer kinetics. Later on, comparative studies of these mathematical models are carried out in order to choose the one which better defines the whole transfer process.

[Imported malaria in Brest hospitals from 1974 to 1980]. / Le Paludisme d'importation dans les hopitaux de Brest de 1974 à 1980.

From 1974 to 1980, 42 confirmed hospital cases of imported malaria occurred in Brest. For 4 cases, we have no information. For the others, 24 care Europeans and 14 non-Europeans. Among the Europeans, the merchant-seamen are the most exposed group. A high proportion of infections are due to Plasmodium falciparum, mainly from black Africa. One patient had a neuropaludism and three had serious attacks. In about half of patients, the initial diagnosis was not malaria. All cases of P. falciparum were due to lack or inadequate chemoprophylaxis.

[Peritoneal cryptococcosis: discussion of clinical facts]. / Cryptococcose péritonéale: discussion d'un fait clinique.

The isolation of Cryptococcus neoformans from peritoneal fluid is a rare event. The authors present the case of a patient with a post-hepatitis cirrhosis and from whom C. neoformans was isolated from the ascitic fluid. The pathogenicity, the origin, the portal of entry of the yeast are discussed.

[Entamoeba polecki infestation in man. Review of the literature apropos of 2 case in Brest]. / Infestation à Entamoeba polecki chez l'homme. Revue de la littérature à propos d'une observation brestoise.

The authors report the observation of an entamoeba polecki infestation in a French woman in professional contact with pigs. Symptoms do not appear to be attributable to the amoeba-infestation but to an associated salmonellosis. The morphology and the pathogenicity of Entamoeba polecki are discussed.
