Social obstetrics: non-local expectant mothers admitted through accident and emergency department in a public hospital in Hong Kong.

OBJECTIVES: To review the pregnancy outcomes of non-booked, non-local pregnant women delivering in Kwong Wah Hospital via admission to the Accident and Emergency Department 1 year after the announcement by the Hospital Authority to stop antenatal booking for non-eligible persons; and to perform a literature review of local studies about non-eligible person deliveries over the last decade. DESIGN: Case series. SETTING: A public hospital in Hong Kong. PARTICIPANTS: All women who held the People's Republic of China passport or the two-way permit and those non-eligible persons whose spouses were Hong Kong Identity Card holders, who delivered in Kwong Wah Hospital from 1 April 2011 to 31 March 2012. RESULTS: Overall, 219 women who were non-eligible persons delivered 221 live births during the study period. Compared with the annual statistics of Kwong Wah Hospital in 2011, non-local mothers were of higher parity; more likely to have hypertensive disease (including pre-eclamptic toxaemia), preterm deliveries (ie at <37 weeks), babies needing admission to the special care baby unit, and macrosomic babies (ie weighing >4.0 kg). The rates of induction of labour and caesarean section were lower in this group. There was no significant difference in the maternal and neonatal outcomes between women who had no booking and those who had a booking in another Hospital Authority or private hospital. There were many incidents of near-miss obstetric complications or suboptimally managed obstetric conditions due to lack of well-structured and continuous antenatal care in this group of non-eligible persons. CONCLUSION: Non-eligible person delivering babies in Hong Kong has become a social obstetrics phenomenon. Despite the introduction of policies, reduction in the number of deliveries (quantity) did not improve the obstetric outcomes (quality). Health care professionals should continue to be prepared for managing the potential near-miss clinical complications in this group of 'travelling mothers'.

Efficacy of birth ball exercises on labour pain management.

OBJECTIVES: To evaluate the efficacy of a birth ball exercise programme conducted by physiotherapists on pain relief, psychological care, and facilitation of the labour process at a labour ward in a regional hospital. DESIGN: Case series with before-after comparisons. SETTING: Kwong Wah Hospital, Hong Kong. PARTICIPANTS: Chinese women admitted to the labour ward for spontaneous vaginal delivery between April and August 2012 were recruited. Physiotherapists taught birth ball exercises in groups or individually for 30 minutes. Labour pain intensity, back pain intensity, frequency of labour pain, stress and anxiety levels, and subjective pressure level over the lower abdomen were captured before and after birth ball exercises. Most of the parameters were measured using self-reported visual analogue scales. After the exercise session, physiotherapists measured the women's satisfaction level. Midwives recorded pethidine usage. RESULTS: A total of 203 pregnant women participated in this programme; 181 were in the latent phase group, whereas 22 were categorised into the no-labour-pain group. In both groups, there were statistically and clinically significant differences in back pain level, stress and anxiety levels, as well as pressure level over the lower abdomen before and after the exercise (P<0.05). In the latent phase group, significant decreases in labour pain and frequency of labour pain were demonstrated. Mean satisfaction scores were high, with visual analogue scale scores higher than 8.2 in both groups. Pethidine usage showed a further decreasing trend (6.4%) compared with the past 2 years. CONCLUSION: Birth ball exercise could be an alternative means of relieving back pain and labour pain in the labour ward, and could decrease pethidine consumption in labouring women.

Successful treatment of spinal cord compression secondary to extramedullary hematopoietic mass by hypertransfusion in a patient with thalassemia major.

A 15-year-old girl with thalassemia major who suffered from paraparesis with a history of progressive lower limb weakness for 2 years immigrated from mainland China to Hong Kong. She had not received regular blood transfusion since the age of 6 years after splenectomy. MRI of the spine showed thoracic spinal cord compression secondary to extramedullary hematopoietic mass. She made significant recovery with hypertransfusion therapy alone. MRI of the spine repeated 3 months later showed nearly complete resolution of the extramedullary hematopoietic mass.

Recurrent catastrophic ceramic femoral head failure in total hip arthroplasty.

Fracture of a modern ceramic head component in total hip replacement is an uncommon but catastrophic complication. Hence, the occurrence of a second ceramic head fracture in the same hip replacement of an individual represents a perishingly rare event. We present the case as a means of highlighting potential risk factors for ceramic head fracture and suggest possible management strategies in such cases.

Prediction of cervical response to prostaglandin E2 using fetal fibronectin.

BACKGROUND: To determine whether presence of fetal fibronectin in cervico-vaginal secretions at term will predict the cervical response to prostaglandin E2 (PGE2) pessaries and successful induction of labor amongst subjects with unfavorable cervices. METHODS: Cervico-vaginal secretion was tested for the presence of fetal fibronectin prior to cervical ripening with PGE2 pessaries in women with a singleton term or post-term pregnancy undergoing induction of labor. The total number of PGE2 pessaries, interval from induction to labor and induction to delivery, latent phase and active phase of labor and cesarean section rate were compared. RESULTS: Women with fetal fibronectin in their cervico-vaginal secretion had better cervical response to PGE2 pessaries and required fewer doses for induction of labor and they took a shorter time interval from induction to delivery. They tend to have a lower cesarean section rate but the figures did not reach statistical significance. CONCLUSIONS: The presence of fetal fibronectin from cervico-vaginal secretions in subjects with a Bishop score <5 is predictive of a favorable response to induction by prostaglandin pessary
