用酶联免疫吸附术观察向附睾注射鱼肝油酸钠后抗精子抗体的变化

本研究用酶联免疫吸附术观察8只家兔在附睾注射鱼肝油酸钠后血清及精浆中的抗精子抗体。血清抗精子抗体阳性率为37.5～50.0%,最早检出率为术后2个月,6～7月达高峰。精浆抗精子抗体阳性率为25%,最早检出率为术后4个月,且此时己达高峰。与输精管结扎资料相比,发现血清抗精子抗体检出率偏低,而精浆相应抗体偏高,表明向附睾注射鱼肝油酸钠引起的免疫反应有别于结扎,以生殖道局部为主。     

A GIANT INTRAOCULAR FOREIGN BODY OF NONMAGNETIC METAL REPORT OF A CASE

A perusal of the medical literature re- vealod only one case of giant nonmetallic in traocular foreign body, 15x11x7 mm, removed in China However, no mention was made of the operative result of the wounded eye in the report. Usually after removal of intraocular foriegn bodies, especially the giant ones, the eyeball becomes inevitably atrophied, thus it has to be enucleated soon after operation. We removed a giant intraocular metallic foreign body, measuring 18.1x9x1.5 mm and weighing 0.24 g, from the left eye of a patient at our clinic. Follow-up l year after operation found that the eyeball of the affected eye was good in appearance with preservation of partial vision.     

Horner syndrome

Horner syndrome is an uncommon but important clinical entity, representing interruption of the sympathetic pathway to the eye and face. Horner syndrome is almost always diagnosed clinically, though pharmacological testing can be used to confirm the diagnosis. Imaging modalities such as PET, CT and MRI are important components of work‐up for patients presenting with acquired Horner syndrome. Our patient’s presentation with Horner syndrome unmasked the causative superior sulcus squamous cell carcinoma and a coincidental lower lobe adenocarcinoma. Successful radical treatment of these cancers resulted in complete resolution of the syndrome and disease‐free survival at 18 months. We review the anatomy and pathophysiology underlying this and other causes of Horner syndrome.     

Is it time to reconsider initial antibiotic treatment strategies for severe urinary tract infections in Europe?

Until recently, most reported cases of bacteraemia caused by multidrug-resistant strains of Enterobacteriacae producing an extended-spectrum beta-lactamase (ESBL) in Europe have been nosocomial in origin. However, increasing numbers of reports of community-acquired bacteraemia and urinary tract infection caused by ESBL-producing microorganisms suggest that the geographical origin of patients should be taken into account as a risk-factor for possible ESBL production. Early identification of patients at high-risk of infection with ESBL-producing microorganisms, based on their geographical origin and travel history, should help to optimise initial antibiotic treatment strategies for severe urinary tract infections in Europe.
