Behavioral responses to artificial food colors.

Twenty-two young children, maintained on a diet that excluded certain foods, were challenged intermittently with a blend of seven artificial colors in a double-blind trial. Parents' observations provided the criteria of response. One child that responded mildly to the challenge and one that responded dramatically were detected. The latter, a 34-month-old female, showed a significant increase in aversive behaviors. These results further confirm previous controlled studies.

Displacement of the abdominal aorta by a pseudocyst of the pancreas.

Cystic lesions are generally thought not to displace the abdominal aorta. A case involving a large cystic mass near the pancreas which was proven to be a pancreatic pseudocyst is presented, with a dynamic nuclear angiogram and a CT scan of the abdomen showing displacement of the aorta.

"Bleeding" of silicone from bag-gel breast implants, and its clinical relation to fibrous capsule reaction.

We present evidence of the following. 1. Modern silicone bag-gel breast implants leak silicone gel through the bag. 2. The amount of silicone leaked by an intact implant varies from one implant to another, and is not constant for any type or brand. 3. The leaked silicone, together with fibrous thickening and various degrees of inflammation will be found in capsules surrounding the implants if extensive biopsies are taken and many sections are examined.

Interventional chest radiology.

Radiologically guided percutaneous drainage procedures are commonly performed to manage a variety of intrathoracic collections. As a natural extension of similar procedures performed for abdominal and pelvic collections, these procedures use both the conventional and cross-sectional imaging modalities to detect intrathoracic collections and to guide safe percutaneous diagnostic aspiration and drainage. The high-resolution images obtainable on current computed tomographic and ultrasound units allow detection of lung abscesses, empyemas, malignant effusions, and infected mediastinal fluid collections that are amenable to percutaneous drainage. Advances in catheter design and introduction techniques have allowed drainage of collections previously managed by open procedures. The ease of fluoroscopically guided catheter placement for treatment of spontaneous or biopsy-induced pneumothorax has provided a safe, effective, and comfortable alternative to blind large-bore surgical tube placement. Transthoracic needle biopsy of lung, mediastinal, and pleural or chest-wall masses has resulted from the availability of image intensifiers and cross-sectional imaging modalities useful in guiding needle placement and tissue sampling. Equally important has been the development of cytopathology as a subspecialty that can provide diagnoses of malignant and benign thoracic conditions from needle aspirates. This technique has had a major impact on the preoperative evaluation of the patient with a solitary pulmonary nodule and has eliminated unnecessary surgery in a significant percentage of such patients. Transcatheter arterial embolization has made a significant contribution to the management of the patient with massive hemoptysis and is the procedure of choice for treatment of pulmonary arteriovenous malformations. A thorough knowledge of the vascular anatomy of the thorax and expertise in catheterization and embolization techniques are prerequisites for the safe performance of these procedures.

Prevalence of antibody to HTLV-III/LAV in a population attending a sexually transmitted diseases clinic.

To determine whether HTLV-III/LAV is transmitted to men by heterosexual contact and whether contact with prostitutes plays a role in such transmission, a serosurvey was conducted in clinics for sexually transmitted diseases in New York City. Two hundred ninety-five male heterosexual nonusers of intravenous drugs were studied. Antibody to HTLV-III/LAV was found in sera from ten men (3.4%); this rate is approximately 15 times the prevalence found in healthy blood donors. Seropositivity was associated with serologic evidence of syphilis (odds ratio, 11.2; 95% confidence interval, 2.1-52) and hepatitis B infection (odds ratio, 9.1; 95% confidence interval, 2.0-55). Antibody to HTLV-III/LAV was not associated with self-reported exposure to prostitutes (odds ratio, 0.8; 95% confidence interval, 0.08-4.2). These findings suggest heterosexual transmission of HTLV-III/LAV to men but fail to implicate contact with prostitutes as a mode of such transmission.

Risk factors for infection with plasmid-mediated high-level tetracycline resistant Neisseria gonorrhoeae.

This study was done to determine whether the increase in high-level tetracycline resistant Neisseria gonorrhoeae (TRNG) was associated with increased tetracycline use. From 547 persons with positive cultures seen consecutively at a sexually transmitted disease (STD) clinic, 51 (9%) isolates were resistant to tetracycline. Of these 51 isolates, 37 (73%) had high-level resistance (TRNG) which was mediated by the tetM determinant located on a 25.2-megadalton plasmid. Women were twice as likely as men to have TRNG. Previous visits to an STD clinic and oral antibiotic use for a sexually transmitted disease within a one to five month period were used as surrogates for prior tetracycline use. Patients who had been to an STD clinic were almost twice as likely to have TRNG (RR = 1.9, 95% CI: 1.01, 3.46), and those who took an oral antibiotic had a relative risk of 1.8. The authors postulate that previous tetracycline use selects for tetM-containing microorganisms in the genitourinary tract that, at the time of gonococcal infection, have the ability to transfer the determinant to N. gonorrhoeae. The above findings might have implications for modifying the current Centers for Disease Control (CDC) recommendation to prescribe tetracycline for suspected Chlamydia infection among patients with gonorrhea.
