Input: Consider Input: Abstract: To determine whether the morphology of dermatophytes plays a role in the clinical manifestation of dermatophytosis, we isolated spores and mycelia from colonies of killed Trichophyton mentagrophytes and tested their ability to induce gross and microscopic cutaneous changes when applied to guinea pig skin. The skin of normal guinea pigs failed to develop any cutaneous changes after inoculation with either dead spores or mycelia. In contrast, guinea pigs that had recovered from a T. mentagrophytes infection reacted to topically applied spores by producing pustules but failed to develop pustules either grossly or microscopically when inoculated with mycelia. Because differences in the activation of C' and the subsequent generation of the polymorphonuclear leukocyte (PMN) chemoattractant, C5a, might account for our in vivo findings, we measured the amount of C5a activated in vitro when serum was incubated with equivalent amounts of spores or mycelia. Spores consistently activated more C' to C5a than mycelia, although each could activate serum C'. The results support previous studies that show a direct correlation between the clinical manifestations of a dermatophytic infection and the development of immunity against the dermatophyte. Furthermore, the data suggest that a dermatophyte's predominant morphology during an infection may play a critical role in producing pustules by activating C' and chemoattracting PMNs into the fungus-laden stratum corneum.

Input: Consider Input: Abstract: A simple preoperative classification is described to predict the intrauterine and ectopic pregnancy rates following distal tubal microsurgery. Laser CO2 microsurgical salpingostomies were performed on 76 patients between January 1979 and January 1984. All of the patients underwent a preoperative assessment, which included hysterosalpingogram and laparoscopy, to formulate a preoperative classification based on a point system. The patients were divided into four groups according to tubal damage, with a subsequent intrauterine pregnancy rate of 58.3% in grade I, 36.6% in grade II, 9.5% in grade III, and 0% in grade IV. The patients were divided into four groups according to adhesions, with a subsequent intrauterine pregnancy rate of 38.8% with no adhesion, 32.0% with mild adhesions, 26.6% with moderate adhesions, and 5.5% with severe adhesions. From these results, a preoperative management is proposed for patients being considered for either distal tubal microsurgery or in vitro fertilization.

Input: Consider Input: Abstract: The measurement of subjective pain intensity continues to be important to both researchers and clinicians. Although several scales are currently used to assess the intensity construct, it remains unclear which of these provides the most precise, replicable, and predictively valid measure. Five criteria for judging intensity scales have been considered in previous research: ease of administration of scoring; relative rates of incorrect responding; sensitivity as defined by the number of available response categories; sensitivity as defined by statistical power; and the magnitude of the relationship between each scale and a linear combination of pain intensity indices. In order to judge commonly used pain intensity measures, 75 chronic pain patients were asked to rate 4 kinds of pain (present, least, most, and average) using 6 scales. The utility and validity of the scales was judged using the criteria listed above. The results indicate that, for the present sample, the scales yield similar results in terms of the number of subjects who respond correctly to them and their predictive validity. However, when considering the remaining 3 criteria, the 101-point numerical rating scale appears to be the most practical index.
