ABSTRACT

Tracheal agenesis is a rare congenital airway anomaly which presents as an airway emergency at birth. We report a case of late premature Chinese infant with tracheal agenesis type II (by Floyd's classification) who presented with severe respiratory distress at birth. He had multiple failed attempts at intubations with accidental oesophageal intubation and ventilation. Tracheal agenesis with tracheo-oesophageal fistula was suspected from an emergency optical laryngoesophagoscopy done. The infant was subsequently stabilized on oesophageal ventilation. The diagnosis was confirmed on CT scan and parents were counseled regarding the poor outcome and decided for withdrawal at day 7 of life.

ABSTRACT

OBJECTIVE: We report a case of an elderly man receiving treatment with perindopril, who presented with angioedema of the left side of the tongue, floor of the mouth and upper neck. This affected his speech and swallowing, and occurred one day after a burr hole and evacuation procedure undertaken to treat a subdural haematoma. The patient was kept under close observation and treated with intravenous hydrocortisone. The angioedema resolved completely in two days. This is the third reported case of unilateral tongue angioedema occurring secondary to angiotensin-converting enzyme inhibitor use. METHOD: Case report and literature review concerning angiotensin-converting enzyme inhibitor induced angioedema. CONCLUSION: Unilateral angioedema of the tongue is a rare adverse reaction to angiotensin-converting enzyme inhibitors. Early recognition may prevent unnecessary surgical intervention and complications.

ABSTRACT

Transforming growth factor-beta (TGF-beta) has been shown to inhibit the growth of mammary epithelial cells and may play a protective role in mammary carcinogenesis. In contrast, oestrogens promote the development of breast cancer. Oestrone sulphate (E1S) is a huge reservoir of active oestrogens in the breast being converted to the weak oestrogen, oestrone (E1), by oestrone sulphatase. E1 is reversibly converted by oestradiol-17beta hydroxysteroid dehydrogenase to the potent oestrogen, oestradiol (E2). The aim of this study was to assess the effect of the TGF-beta1 isoform on growth and oestrogen metabolism in the hormone-dependent MCF-7 and hormone-independent MDA-MB-231 human breast cancer cell lines. The results showed that TGF-beta1 significantly inhibited cell growth and stimulated the conversion of E1S to E1 and E1 to E2 in the MCF-7 cell line. In the MDA-MB-231 cell line TGF-beta1 significantly stimulated cell growth and inhibited the interconversions between E1 and E2. In conclusion, the growth inhibitory effect of TGF-beta1 on the MCF-7 cell line would appear to confer a protective effect in breast cancer. However, its ability to increase the amount of E2 would increase the risk of breast cancer. Which of these effects predominates in vivo remains to be explored. The growth stimulatory effect of TGF-beta1 on the MDA-MB-231 cell line probably acts through a mechanism independent of the effect of TGF-beta1 on oestrogen concentrations since this cell line is hormone unresponsive.
