[Brucellar orchiepididymitis].

The brucellosis is an unusual entity whose incidence has diminished due to the improvement in preventive measures. We have carried out a retrospective study of all the patients admitted in our service between 1996 and 1998, with diagnosis of orchitis. Two of the 31 patients admitted for this reason presented a final diagnosis of brucellar orchiepididymitis. Both patients presented clinic of affectation from the general state accompanied by resistance to habitual antibiotic treatment. The patient's epidemic antecedents, accompanied by the suitable clinical evolution took to the suspicion of orchiepididymitis of brucellar etiology, with change in the antibiotic rule. The diagnosis of the process was obtained by means of serologic tests and blood cultures.

Lactic dehydrogenase-C4 activity in seminal plasma and male infertility.

OBJECTIVE: To determine the lactate dehydrogenase C4 (LDH-C4) isoenzyme activity in seminal fluid with the purpose of studying its clinical use as marker of seminiferous epithelium activity. DESIGN: A total of 224 semen samples were classified into the following four groups: [1] men with proven fertility (n = 27); [2] oligozoospermic patients (n = 34); [3] normozoospermic subjects with infertile couple (n = 120); and [4] vasectomized patients (n = 22). RESULTS: It was found that LDH-C4 activity discriminates well between the infertile groups (groups 2 and 3) with the fertile group (group 1). We correlated LDH-C4 activity with the different parameters of the seminogram, the best correlation being obtained with the sperm count. Lactate dehydrogenase-C4 activity:sperm count ratio showed a high correlation with the "vital" variables of spermatozoon. The logistic regression analysis gave a mathematical model that only includes viability and percent C4. This model accurately classifies 88.4% of the cases. In vasectomized individuals, we proved an earlier disappearance of the LDH-C4 activity, than that of the sperm count. CONCLUSION: Our results confirm the clinical utility of this parameter as a good marker for both germinal activity and spermatozoid quality.
