[Thoracic radiography in Pneumocystis carinii pneumonia in AIDS patients. Presentation forms and clinical course].

BACKGROUND: We intend to determine the frequency of the different radiographic findings of Pneumocystis carinii pneumonia in patients with AIDS. METHODS: We retrospectively review the chest roentgenograms of 30 patients at admission to the hospital (group I [n = 30]), at follow-up (group II [n = 30]) and after clinical recovery (group III [n = 15]). RESULTS: Diffuse bilateral interstitial disease was the most frequent radiographic finding at admission (76.6%) and at follow-up (60%). Atypical radiographic findings were: normal chest radiograph (group I [n = 3]), nodules (group I [n = 2], group II [n = 2], group III [n = 1]), thin wall cysts (group II [n = 1], group III [n = 1]), cavitated lesion (group II [n = 1], group III [n = 1]), pneumothorax (group II [n = 2], group III [n = 1]), pleural effusion (group III [n = 2]), asymmetrical distribution of the pulmonary lesion (group I [n = 2], group II [n = 3]) and predominant upper lobe involvement (group II [n = 1], group III [n = 1]). The atypical findings were greater during follow-up (group II [n = 33.3%], group III (46.6%) than at admission (group I [n = 23.4%]). CONCLUSIONS: It is important to know the frequency and multiplicity of the radiographic findings of Pneumocystis carinii pneumonia in order to establish the diagnosis and differentiation from other infectious diseases or other causes of pulmonary disease in patients with AIDS.

Binding of a synthetic targeting peptide to a mitochondrial channel protein.

Membrane crystals of the mitochondrial outer membrane channel VDAC (porin) from Neurospora crassa were incubated with a 20-amino-acid synthetic peptide corresponding to the N-terminal targeting region of subunit IV of cytochrome oxidase. The peptide caused disordering and contraction of the crystal lattice of the membrane arrays. Also, new stain-excluding features were observed on the peptide-treated arrays which most likely correspond to sites at which the peptide accumulates. The stain exclusion zones associated with binding of the targeting peptide (and with binding of apocytochrome c in an earlier study) have been localized on a two-dimensional density map of frozen-hydrated, crystalline VDAC previously obtained by cryo-electron microscopy. The results indicate that both the peptide and cytochrome c bind to protein "arms" which extend laterally between the channel lumens. The finding that imported polypeptides bind to a specific region of the VDAC protein implicates this channel in the process by which precursor proteins are recognized at and translocated across the mitochondrial outer membrane.

Therapeutic touch and post-Hurricane Hugo stress.

This repeated-session design sought to answer questions about the effectiveness of therapeutic touch in reduction of stress for 23 individuals following a natural disaster. In addition, methodological issues related to the average length of time for a therapeutic-touch treatment and a method of documenting the nonverbal interaction between subject and toucher were investigated. Findings indicate that stressed people report themselves to be less stressed following therapeutic touch (p = .05). Time of therapeutic-touch intervention varied significantly between the touchers, with a range of 6.8 to 20 minutes. Qualitative data examining the interaction of toucher and subject raised a number of questions that require further study.

Papanicolaou smear adequacy: effect of different techniques in specific fertility states.

Six hundred fifty-four Papanicolaou smears were studied prospectively to determine the yield of endocervical cells within specific fertility states by technique used. Smears from postmenopausal women had the lowest yield of endocervical cells (32 percent, P less than 0.01). Smears from postpartum women had a higher yield of endocervical cells than those from pregnant women (69 percent vs 59 percent, P greater than .05). Swabbing excess mucus from the cervix prior to scraping uniformly improved the yield of endocervical cells (70 percent vs 62 percent, P less than .02). In swabbed postmenopausal women, use of a Milex spatula had a significantly higher yield than the use of a wooden spatula and a cotton-tipped applicator (43 percent vs 27 percent, P less than .03).

Diagnosis of dengue by using reverse transcriptase-polymerase chain reaction.

A rapid identification of dengue viruses from clinical samples by using a nested reverse transcriptase-polymerase chain reaction (RT-PCR) procedure was carried out for diagnostic and epidemiological purposes. RT-PCR identified DEN-1 and DEN-2 viruses in 41% (41/100) of previously confirmed cases and provided an accurate confirmation of DHF in four fatal cases. RT-PCR was also useful for detecting and typing dengue viruses in suspected cases, allowing a rapid identification of new serotypes in endemic areas.
