The prognosis of cancers is conditioned by tumoral extension. We report a case of a squamous carcinoma of the vulva where pathological examination had been at fault. An immunohistological study performed with monoclonal antibodies revealed a lymph node micro-metastasis. This case emphasizes the importance of estimating the tumoral extension by simultaneous pathological and immunological examinations.
Pregnant Wistar rats were given by subcutaneous route 1 of 3 different adrenoreceptor blockers, 2 of them mainly beta-blockers. P5 and P7 group received propranolol (5 and 7 mg/kg respectively), L10 and L20 groups received labetalol (10 and 20 mg/kg) and B5 group received betaxolol (5 mg/kg). Drugs were given daily from the 7th to the 16th day of gestation. A control group received saline injections. 16 out 24 treated mothers delivered prematurely on the 21st day of gestation. Functional renal parameters were studied in neonates on the first day of life. Renal function of the full term rats prenatally exposed were compared with controls. Average body weight was higher in P5 but lower in L10-L20-B5 groups. Diuresis increased in L20. Creatinine clearance, urinary/plasmatic creatinine ratio and urea clearance decreased in L10-L20 groups and fractional excretion of H2O increased in L20. Thus these adreno- and beta-blockers given to pregnant rats induced a shorter gestation. Moderate functional renal effects were observed in all neonates.
One case of uremic-haemolytic syndrome associated with an ectopic pregnancy is reported. The main signs are, from the clinical standpoint, a diffuse haemorrhagic syndrome and, from the biological standpoint, a haemolytic anemia, renal failure and thrombopenia. This pathology, exceptionally associated with an early pregnancy, required an intensive resuscitation with blood transfusion, hemodialysis and plasma exchanges. From a surgical standpoint, two procedures were necessary following salpingectomy, to drain intraperitoneal and sub-aponeurotic blood collections. The course, thereafter, was uneventful.
OBJECTIVE: Classify antibiotics according to their individual activity so as to identify those suitable for empiric therapy. METHODS: We studied bacterial strains isolated from patients with urethritis (n = 189) and upper genital tract infections (n = 163) between June 1994 and February 1995 in 3 hospital and 4 community laboratories. Upper genital tract infections were divided into two groups: proven infection on laparoscopy specimen (n = 79) and suspected infection with isolation of pathogen in cervical samples (n = 84). Pathogens isolated were: Chlamydia trachomatis in 36/12/15 cases respectively, Mycoplasma hominis in 12/20/13, Ureaplasma urealyticum in 55/30/15, Neisseria gonorrhoeae in 40/2/0, Haemophilus spp in 20/2/1, group B streptococci in 7/1/8, E. coli in 8/1/17 and miscellaneous in 11/8/15. The minimal inhibitory concentrations for all strains were determined in 4 laboratories for ofloxacin, erythromycin and doxycyclin against C. trachomatis, M. hominis and U. urealyticum, and for ofloxacin, erythromycin, doxycyclin, amoxicillin+clavulanate, cefotaxime and gentamicin against the other strains. The activity score (% susceptibility to each antibiotic weighted by the frequencies of each isolate in urethritis and upper genital tract infection based on recent French epidemiologic data) was calculated for each antibiotic. CONCLUSION: The antibiotics with the best empiric activity scores in urethritis were, in decreasing order: doxycyclin (90.4%), ofloxacin (88.1%), and erythromycin (50.2%). The most active combinations in upper genital tract infections were ofloxacin+amoxicillin (100%), doxycyclin+cefotaxime+metronidazole (95.9%) and doxycyclin+amoxicillin (95.3%).
Endometritis are upper genital tract infections. They are part of the Pelvic Inflammatory Diseases and are often difficult to differentiate from salpingitis. C. trachomatis, a sexually transmitted micro-organism, is a major pathogen of the genital tract. Most of the time, the upper genital tract infections are polymicrobial and C. trachomatis can be combined with other aerobes (E. coli, streptococci...) and anaerobes. Diagnosis of chlamydial endometritis is difficult since the clinical symptoms--lower abdominal pain, cervical discharge--often lack specificity or can be completely absent. Bacteriological studies from intra-uterine or intra-cervical samples are necessary. A laparoscopy can be useful to ascertain the integrity of Fallopian tubes. The treatment requires broad spectrum antibiotics effective against C. trachomatis and other probable pathogens, for 2 to 3 weeks.
