Placenta accreta is a condition of abnormal placental implantation in which the placental tissue invades beyond the decidua basalis. It may invade into or even through the myometrium and adjacent organs, such as the urinary bladder. The incidence has been rising in recent years. It is one of the important obstetric complications nowadays, leading to significant maternal morbidity and mortality. In the past, this condition was often diagnosed at the time of delivery when massive and unexpected hemorrhage occurred. Hysterectomy, associated with significant physical and psychological consequences, was usually the only management option. As more obstetricians have become aware of this condition, early identification with antenatal imaging diagnostic technology has become possible. Ultrasound scan plays an important role in the antenatal diagnosis. Various sonographic features with different specificity and sensitivity have been described in the literature. In equivocal cases, magnetic resonance imaging may be helpful. With such information, more accurate counseling can be offered to the mothers and their families before delivery. The delivery can also be arranged at a favorable time and in an institution where multidisciplinary support is available. Input from a hematologist, interventional radiologist, intensive care physician, urology surgeon, and/or other specialist are desirable. Apart from hysterectomy, various forms of conservative management can also be considered when the diagnosis is made prior to delivery. Fertility can therefore be preserved. After delivery, with or without hysterectomy performed, psychological support to the mothers and their families is essential.

Objective To compare the psychological impact following early miscarriage between women who conceived naturally and women who conceived following assisted reproduction.Design Prospective cohort study.Setting Assisted reproduction clinic and general gynaecological unit in a university-affiliated, tertiary referral hospital.Population A cohort of 150 women (75 after natural conception; 75 after assisted reproduction).Methods Completed semi-structured interviews using two standard questionnaires [the 12-item General Health Questionnaire (GHQ-12) and the 22-item Revised Impact of Events Scale (IES-R)], at 1, 4, and 12 weeks after a diagnosis of first-trimester miscarriage.Main outcome measures The GHQ-12 and IES-R scores for the two groups of women.Results The GHQ-12 and IES-R scores were significantly higher in the assisted reproduction group than the scores in the natural conception group, at 4 weeks and 12 weeks after miscarriage. Further breakdown of the scores revealed significantly higher hyperarousal symptoms at 4 and 12 weeks in the assisted reproduction group, indicating the traumatic effect of miscarriage to these women.Conclusions Following first-trimester miscarriage, subfertile women who conceived after assisted reproduction had higher stress and anxiety-depression levels, and experienced more traumatic impact from the event, than those after natural conception. A timely support and psychological intervention would be beneficial in the management of this group of women.Keywords Anxiety, assisted reproduction, depression, miscarriage, subfertility.Please cite this paper as: Cheung C, Chan C, Ng E.

Occupational risk factors of carpal tunnel syndrome (CTS) are popular current research targets, with main emphasis put on wrist posture and dynamics. In this study, we do not intend to pinpoint individual occupations, but aim to identify high risk wrist postures and actions which may occur across various occupations. It is hoped that prevention can thus be instituted in a general population by directing at the particular causative wrist actions rather than exclusively targeting isolated occupations. We performed a case-control study with 166 cases and 111 controls recruited from different hospitals in Hong Kong in 2004. All cases and controls completed the survey on their general health condition, smoking status, wrist posture and motion as well as psychosocial status at the time of diagnosis of CTS. Frequent flexion OR = 4.436 (95% CI: 1.833-10.734), frequent extension OR = 2.691 (95% CI: 1.106-6.547) of the wrist were found to be associated with CTS. Frequent sustained forceful motion of the wrist OR = 2.588 (95% CI: 1.144-5.851) was also found to be associated with CTS. Neutral wrist position and repetitive wrist motion were not associated with CTS. Adjustment was made for age, sex, BMI, smoking and psychosocial stress. Our study confirms that frequent flexion, extension and sustained force of the wrist increase the risk of developing CTS.
