A case of spontaneous rupture of uterine artery in the second trimester of pregnancy is described. Haemorrhage from rupture of uterine artery during pregnancy was discovered at laparotomy. This was an unusual but serious complication of pregnancy. This condition is extremely rare and one must consider it in cases of incomprehensible abdominal pain with or without haemodynamic collapse. A review of the literature revealed only four similar cases so far. This pregnancy continued till 37 weeks pregnancy and had a spontaneous vaginal delivery. Immediate institution of effective resuscitative measures and early surgical intervention were essential to both foetal and maternal survival.

·AIM: To report a rare case of antiphospholipid syndrome presenting as papilledema and sixth nerve palsy in right eye due to superior sagittal sinus thrombosis, and regression of papilledema following anticoagulation and acetazolamide therapy.·METHODS: A 44-year-old Chinese gentleman presented with headache, diplopia and mild blurring of vision. Clinical examination revealed the presence of sixth nerve palsy in right eye and papilledema. There was enlargement of blind spot in the visual fields and red green deficiency in both eyes.Computed tomography and magnetic resonance imaging showed superior sagittal sinus thrombosis. Hematological investigation confirmed the presence of antiphospholipid syndrome as the underlying cause.·RESULTS: The condition was treated successfully in three months with the adjunctive use of anticoagulation and acetazolamide. Reversal of papilledema changes in the optic disc to normal indicates the anatomical recovery, while reduction of enlargement of blind spot to normal size,recovery of red green deficieny to normal colour vision in both eyes and visual improvement after regression of papilledema in right eye indicate functional recovery in this patient.·CONCLUSION: Antiphospholipid syndrome should be considered in the differential diagnosis of papilledema, and oral acetazolamide is an important adjunct therapy to anticoagulation in cases of refractory papilledema to protect the optic nerve from potential damage which results in blindness.

Indication for pediatric tracheostomy has changed. Upper airway obstruction secondary to infectious disorders is no longer the commonest indication. The aim of this study was to establish data on indications, outcome and complications of pediatric tracheostomy. A retrospective analysis of pediatric tracheostomies carried out between March 2002 to March 2004 was done. Eighteen patients were identified. The commonest indication was prolonged ventilation (94.5%) followed by pulmonary toilet (5.5%). None was performed for upper airway obstruction. Postoperative complications were encountered in six patients (33.3%), the commonest being accidental decannulation notably in children less than six years of age. Twelve patients (66.6%) were successfully decannulated. The mortality rate was 16.6%. All death were non tracheostomy related. The commonest indication for tracheostomy was prolonged ventilation and tracheostomy in children is relatively safe despite complications.

Mbd3 (Methyl-CpG binding domain protein), a core member of NuRD (nucleosome remodelling and deacetylation) is essential for embryogenesis. However, its role in reprogramming of somatic cells into induced pluripotent stem cells (iPSC) remains controversial. Some reports suggest that Mbd3 inhibits pluripotency, whilst others show that it greatly enhances reprogramming efficiency. Our study is the first to assess the role of Mbd3 on reprogramming of primary human fibroblasts using Yamanaka episomal plasmids (Reprogramming factors (RF) under feeder-free conditions. We showed that shRNA-mediated partial depletion of Mbd3 resulted in >5-fold reduction in the efficiency of reprogramming of primary human fibroblasts. Furthermore, iPSC that emerged after knock-down of Mbd3 were incapable of trilineage differentiation even though they expressed all markers of pluripotency. In contrast, over-expression of the Mbd3b isoform along with the Yamanaka episomal plasmids increased the number of fibroblast derived iPSC colonies by at least two-fold. The resulting colonies were capable of trilineage differentiation. Our results, therefore, suggest that Mbd3 appears to play an important role in reprogramming of primary human fibroblasts, which provides further insight into the biology of reprogramming but also has direct implication for translation of iPSC to clinic.

INTRODUCTIONThe development of secondary tumours as a result of radiation therapy is a rare but serious complication.

CLINICAL PICTUREThis is a case report of a 45-year-old Chinese male who developed postirradiation sarcoma of the sphenoid bone in less than 5 years after radiation therapy for Stage T3N1M0 nasopharyngeal carcinoma.

DISCUSSIONIn the literature, the only case of postirradiation osteosarcoma of the sphenoid bone was after radiation therapy for craniopharyngioma. There was no previously reported case of postirradiation sarcoma of the sphenoid bone after radiation therapy for nasopharyngeal carcinoma.

CONCLUSIONThis is the first case of postirradiation malignant fibrous histiocytoma of the sphenoid to be reported. Of about 3000 patients treated with radiotherapy for nasopharyngeal carcinoma over a 10-year period in Singapore, only 1 patient developed postirradiation tumour of the sphenoid bone.
