A rare case of primary malignant intramedullary lymphoma, localized in the cervical part of the spinal cord, is presented. The onset of clinical symptoms was associated with herpes zoster infection. Surgery led to the histological diagnosis. The clinical investigations excluded the presence of lymphoma in other sites in the central nervous system and in the extraneural organs. Postoperative irradiation and chemotherapy effected relict of neurological symptoms. 相似文献

NADPH-diaphorase positive (NDP) neurons and nerve fibers were found in the spinal dorsal horn (DH) and sensory ganglia of
the turtle Chrysemys d’orbigny. Three well-defined types of NDP neurons were found in the DH: (a) elongated nerve cells with two radially arranged dendritic
branches, (b) neurons with rostro-caudal dendritic branches, (c) bitufted neurons with two, practically symmetric branches
that project to the ipsilateral and contralateral dorsal horns. A combination of the techniques that reveal NADPH-diaphorase
activity with the horseradish peroxidase transganglionic labeling of the dorsal root collaterals, suggested that NDP neurons
of the DH are second-order cells of the spinal sensory pathway. NDP neurons were also found in the spinal sensory ganglia
at all metameric levels. Our findings indicate that the DH of turtles, like that of mammals, contains both the enzymatic machinery
and the neural connections required to postulate the participation of nitric oxide in ”plastic phenomena” such as hyperalgesia
and central sensitization. Two other alternatives or complementary hypotheses are discussed: (a) NDP neurons in the DH and
sensory ganglia may represent specific cell populations involved in the processing of sensory visceral information; (b) NADPH-diaphorase
reactivity may indicate sustained levels of neuronal activity.

Spermatogenic function was studied in 10 patients, previously diagnosed as having primary hypothyroidism, in whom a state of hypothyroidism has been induced by discontinuation or a decrease in treatment with levothyroxine over at least one spermatogenic cycle. Most of the patients had fathered children before the study. When the results obtained in the hypothyroid state were compared with those from a group of 16 controls with proven fertility, slight anomalies were observed; these were characterized by a decrease in seminal volume (p less than 0.05), progressive forward motility (p less than 0.01), and the cumulative percentage of mobile forms (p less than 0.01). There were no anomalies in sperm density or in the percentage of spermatozoa with normal morphology. No alterations in circulating levels of testosterone and gonadotropins existed. Induction of hypothyroidism did not lead to seminal or hormonal modifications compared with the same patients in a situation of euthyroidism. Short-term postpuberal hypothyroidism did not cause seminal alterations sufficiently intense to induce male infertility. 相似文献

Fifty-four patients with complicated UTI were administered ciprofloxacin in doses of 500 mg (30 subjects) and 250 mg (24 subjects)
at 12-hour intervals. While a positive effect was noted in 96–100% upon termination of therapy, the effect was still present
3 weeks later in 90% of the high-dose, but only in 71% of the low-dose group. In 23 patients with uncomplicated UTI, a positive
effect of the three-day therapy with 100 mg of ciprofloxacin at 12-hour intervals was observed in 91% of subjects.
Intolerance to the agent was found in one case only. Development of resistance to ciprofloxacin was not observed. 相似文献

Cryotherapy of the cervix was made in 40 patients for chronic cervicitis, and the thickness of the ice zone around the probe was measured in function of treatment time, under standard cooling conditions. The pace of growth of the ice zone allowed the author to draw conclusions as to the conductivity of the studied tissue. It was established that in the study-group, the patient's age and their histories of abortions did not influence the cold transfer significantly. The difference between the average values of ice zone thickness measured in the groups of nulliparae and multiparae was, however, significant. Findings have shown that the spread of cold in the cervical tissue in nulliparous women is better than in multiparae and so a greater efficacy of cryotherapy can be expected in nulliparae. 相似文献
