An unusual presentation of a vaginal leiomyoma in a postmenopausal hysterectomised woman: a case report

Leiomyomas are benign tumours commonly occurring in the uterine wall. They are rarely seen in the vaginal wall leading to pressure symptoms on urinary tract. Indentation of leiomyoma from anterior vaginal wall into the bladder is rare and hence we report one such case. A 55 year old Caucasian woman presented to urology clinic with recurrent Urinary tract infection and pressure symptoms. After the diagnosis of a vaginal mass, she was referred to Gynaecology clinic. During the excision of the vaginal mass its indentation into the bladder was noted. Histology report confirmed the diagnosis of benign leiomyoma

Ruptured ovarian cystic teratoma in pregnancy with diffuse peritoneal reaction mimicking advanced ovarian malignancy: a case report

<p>Abstract</p> <p>Introduction</p> <p>This case illustrates the unusual complication of granulomatous peritonitis following rupture of a dermoid cyst in pregnancy resembling disseminated ovarian carcinoma. To the best of the authors' knowledge, this is the first report of this complication during advanced pregnancy in the literature.</p> <p>Case presentation</p> <p>A dermoid cyst ruptured during surgical removal in the second trimester of pregnancy in a 27-year-old primigravida. Postoperatively the patient suffered pulmonary embolism and leakage of sebaceous material through the abdominal wound. She gradually developed significant abdominal distension, gastrointestinal symptoms and lost more than 8 kg of weight in the 12 weeks postoperatively. The baby was delivered at 31 weeks by a technically challenging caesarean section owing to severe dense adhesions obscuring the uterus. Bowel resection was performed for suspected malignant infiltration and adhesion causing obstruction. She had a protracted convalescence with an ileostomy and mucus fistula. Histology confirmed granulation without malignancy. One year following the surgical treatment, she had recovered well and was planning her next pregnancy.</p> <p>Conclusion</p> <p>Although granulomatous peritonitis following rupture of a dermoid cyst is very rare, awareness is the key to diagnosis and appropriate management. Per-operative frozen section may be helpful.</p

Glass composition for spinning fiber

The performance of polymer composites reinforced with neutral glass fibres was compared with that of “E” glass reinforced composites. The strength and fatigue characteristics of composites, and the polymerisation kinetics at the glass-polymer interface, were studied. The results show that “N” glass fibre composites possess superior wet strength and are suitable for general application

Microstructure and properties of a new porcelain composition containing crystallizing glasses as replacement for feldspar

The effect of crystallising glasses, as replacement for feldspar, on the microstructure and mechanical properties of classical porcelain has been studied. It has been found that the complete replacement of feldspar by crystallising glasses increased the fracture strength, toughness and elastic modulus of the material. The improvements are attributed to sharp changes in the microstructure as a result of a significant reduction in the content of glass phase and the appearance of a cordierite phase in its place

Effect of glass-ceramics and sillimanite sand additions on microstructure and properties of porcelain

Both quartz and feldspar were progressively replaced by ground sillimanite sand and glass-ceramics in a classical porcelain composition and the effect of these replacements on the vitrification behaviour and mechanical and thermal properties in relation to the microstructure of specimens has been investigated. Progressive additions of sillimanite sand and crystallising glasses leading to the complete replacement of quartz and feldspar increased the strength, toughness and modulus significantly, and drastically reduced the per cent thermal expansion in the composition. The improvement in the properties is attributed to dramatic changes in the microstructural features as a result of significant reduction in the content of glassy phase and the simultaneous increase in crystalline phases such as mullite, sillimanite and cordierite
