Severe Vaginal Stenosis Simulating a Transverse Septum with Huge Hematocolpos in an Hiv-patient: How to Make a Break in the Wall?

Triangularia backusii n. sp. was isolated from a soil sample collected in Ohio, U.S.A., and was subjected to alcohol treatment. Triangularia backusii is characterized by oval to pyriform perithecia, elongate-clavate asci, and obovoid ascospores with hyaline, gelatinous appendages. The ascospores are two-celled with a transverse septum; the upper cell is obovoid with a truncate base and brownish black to black and the lower cell is triangular and pale brown to brown. The conidial state is assignable to the genus Phialophora. The new species differs from other known Triangularia species in having the largest ascospores.

Background: Pelvic radiotherapy may damage the vagina and cause vaginal stenosis. Its incidence in the literature ranges from 1.2% to 88%. To prevent vaginal stenosis, routine vaginal dilation is recommended during and after pelvic radiotherapy. Materials and Methods: The objective was to examine critically the evidence behind this guideline. Searches included the Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and Google scholarly articles. All the relevant articles were included in the study. Discussion: Various studies gave recommendations on dilation during or immediately after radiotherapy. Literature does not support routine vaginal dilatation during or immediately after pelvic radiotherapy. Occasional penetration might prevent the sides of the vagina adhering to each other, and dilation might be valuable once the inflammatory and psychological scarring has settled. Two trials demonstrated that encouraging vaginal dilation increased patient compliance, but no difference was found in sexual function scores in the first trial. One retrospective study reported that dilation lowered stenosis rates, but the control group is not comparable. One study involving 89 women revealed that the median vaginal length was 6 cm, six to ten weeks after radiation therapy, but women tolerated a 9-cm dilator/measurer after 4 months of dilation experience. One trial showed no significant advantage by inserting mitomycin C. A study of five women reported that vaginal stenosis can be treated by dilation even many years after radiotherapy. Dilation during or immediately after radiotherapy can cause damage, and there is no evidence that it prevents stenosis. Dilation might stretch the vagina if commenced after the inflammatory phase. Dilation has been associated with traumatic rectovaginal fistulae and psychological consequences. Conclusion: Vaginal dilation might help treat the late effects of radiotherapy, but it must not be assumed that this applies to the acute toxicity phase. Routine dilation during treatment is not supported by good evidence. Prophylactic and therapeutic dilation therapy needs to be considered separately and research is needed to determine when dilation therapy should start on a large population.

Transverse Septum

Phaeotrichum hystricinum Cain and Barr is described from specimens collected in Ontario, Vermont, New York, and Michigan and is made the type species of a new genus. It has been found on porcupine dung from numerous localities. The black, shining, superficial ascocarps are covered with scattered straight black appendages. The clavate stalked asci are in irregular fascicles, eight spored, and with a firm wall which is evanescent at maturity. The ascospores are two-celled, thick-walled, deeply constricted, and readily separating at the transverse septum. There is a large conspicuous germ pore at each end of the ascospore. P. circinatum Cain is described from specimens collected on lemming dung in Northern Ungava, Quebec. This species is distinguished from the former by means of the appendages, which are stouter and curved at the apex. These two species are closely related and very similar to the ostiolate Trichodelitschia bisporula (Crouan) Munk. The new genus is made the type of a new family of cleistocarpous Ascoloculares, with a discussion on the evolution, in many Ascomycete taxa, of cleistocarps adapted either to the utilization of special agencies, rather than air currents, for carrying the ascospores or to delayed dispersal.

Ultrastructure of teliospores and promycelium and basidiospore formation in the two-spored form of Gymnoconia nitens, one of the causes of orange rust of Rubus

Rubus Argutus

Gymnoconia nitens (Schwein.) Kern & H. W. Thurston consists of two forms that cause orange rust of Rubus . The teliospores of both of these forms are morphologically identical to aeciospores, but upon germination form promycelia that give rise to either two or four basidiospores. In this study, we examined the teliospores and the sequence of events leading to basidiospore development in the two-spored form of G. nitens. The teliospores of this species are formed in chains from uninucleate sporogenous cells that line the base of each sorus on infected Rubus argutus Link. (blackberry) leaves. Fluorescence microscopy revealed that approximately 90% of the mature teliospores were uninucleate. During germination, the teliospore nucleus migrated into the developing promycelium and underwent a single mitotic division. A transverse septum formed between the two daughter nuclei creating two uninucleate cells. A tapered sterigma arose from each cell and gave rise to a basidiospore. These findings indicate that the basidiospores of the two-spored form of G. nitens were formed in an asexual fashion.
