Background: Little is known about the effect of maternal perceived breastfeeding self-efficacy on the exclusive breastfeeding rate at 6 months postpartum in mainland China., Objective: The aim of this study was to examine the relative effect of maternal breastfeeding self-efficacy and selected relevant factors on the exclusive breastfeeding rate at 6 months postpartum. The internal consistency and construct validity of the Chinese (Mandarin) version of the Breastfeeding Self-Efficacy Scale-Short Form (BSES-SF) were also examined., Methods: This was a prospective cohort study conducted at a regional teaching hospital in Guangzhou, China. A total of 562 in-hospital mothers who were within 72 hours postpartum were recruited to the study and followed up by telephone for 6 months., Results: Although all of the mothers breastfed their babies within 72 hours postpartum, only 25% of the mothers breastfed exclusively. The mean survival time of continuation of exclusive breastfeeding was 16.7 days. The proportion of mothers who breastfed exclusively after discharge was 14.8%, 2.0%, and 0.2% at 1, 4, and 6 months, respectively. Cox regression analysis revealed that the mothers who had a higher BSES-SF score at baseline, underwent cesarean section, and practiced exclusive breastfeeding within 72 hours after delivery were significantly associated with a lower hazard of discontinuation of exclusive breastfeeding before 6 months postpartum., Conclusion: The exclusive breastfeeding rate among Chinese women is far from satisfactory. The Chinese (Mandarin) version of the BSES-SF can help in identifying mothers who need more support for exclusive breastfeeding before 6 months postpartum.

Purpose: To review records of 166 patients who underwent treatment for Mycobacterium marinum tenosynovitis of the hand and wrist to identify factors associated with functional outcome., Methods: Records of 97 men and 69 women aged 13 to 85 (mean, 50) years who underwent treatment for suspected M marinum tenosynovitis of the hand and wrist were retrospectively reviewed. All underwent open biopsy; synovectomy was performed when florid synovitis was present. Rifampicin and ethambutol were usually prescribed. Clarithromycin, minocycline and/or levofloxacin were used as adjuvants if there was drug intolerance, allergy, or relapse. The duration of antibiotic treatment depended on the clinical recovery. Patients were followed up for one year after completion of drug treatment. Functional outcome was considered excellent for those with >195º total active motion (TAM) and >75% return of motion, good for those with 130º to 195º TAM and 50 to 75% return of motion, fair for those with 65º to 129º TAM and 25 to 49% return of motion, and poor for those with<65º TAM and <25% return of motion., Results: The mean delay in presentation was 4.9 (0.3-120) months. 93 of the patients presented with disabilities (flexion deformity or reduced range of motion), 64 of whom presented one month after injury. 37 (22%) of the patients had received intralesional steroids prior to admission, 30 of whom presented one month after injury. 32 (19%) patients were treated with antibiotics alone, whereas 134 (81%) patients underwent debridement in addition to antibiotic treatment. The mean duration of antibiotic treatment was 7.2 (range, 0-29) months. Of the 156 patients who completed the follow-up, functional outcome was satisfactory in 128 (82%) and unsatisfactory in 28 (17%). Steroid injections and late presentation led to worse functional outcome. Patients with unsatisfactory outcome were more likely to have received intralesional steroid injections (43% [16/37] vs. 10% [12/118], p<0.001, Pearson Chi squared test), have presented >2 months after injury (27% [21/79] vs. 9% [7/77], p=0.004, Pearson Chi squared test), and have undergone synovectomy (23% [28/124]) vs. 0% [0/32], p=0.001, Fisher's exact test). Worse functional outcome correlated with late presentation (r=0.218) and the greater number of debridement procedures (r=0.453)., Conclusion: Delayed antibiotic treatment of M marinum infections and steroid injections were associated with unsatisfactory outcome. Clinicians must have a high index of suspicion for this condition and avoid inappropriate management such as intralesional steroid injections. Public awareness to this condition should be raised.

We report a case of symptomatic non-union of the triquetrum with pseudoarthrosis in a 34-year-old man. Motion of the pseudoarthrosis was noted from radial to ulnar deviation. The patient was treated with bone grafting and screw fixation. The non-union healed and the symptoms subsided. The Mayo wrist score had improved from 65 (fair) to 90 (excellent).

Misdiagnosis and delayed treatment of Mycobacterium marinum infection is common because of its diverse manifestations. This leads to inappropriate use of antimicrobials, extension of the infection from the skin to the tenosynovium, and a poor prognosis (loss of tendons and prolonged immobilisation, secondary to multiple debridements and joint contractures). Clinicians should be aware of this type of infection, especially in subjects at risk (fishermen and aquarium enthusiasts), and those with a history of trauma coupled with exposure to water or marine life. A proactive approach to obtain a biopsy for histopathological and microbiological diagnosis is advised. Anti-mycobacterial treatment should be started promptly. The combined use of rifampicin, ethambutol, and clarithromycin appears to be effective, and debridement is indicated in patients with deep-seated infections.

A rare case of trans-triquetral dorsal perilunate dislocation is described. It differs from the Mayfield and Johnson theory of progressive perilunar instability in greater arc injuries which states that the injury passes from the radial to the ulnar carpal bones and soft tissues in stages. This injury supports the concept of a reverse greater arc injury from ulnar to radial being possible with the radial carpal bones being spared in some cases.

Specialized and advanced psychiatric nursing practice is an innovative concept in the health care service in Hong Kong. A clear definition of the role and practice of psychiatric clinical nurse specialists (CNS) is important for the development of expert psychiatric nursing practice but is still in a formative stage. A qualitative exploratory study was conducted to identify the psychiatric CNS's perceptions of their role and to compare their perceptions with those of their clinical psychiatric nurse colleagues. The main themes emerging from interviews, observations, and personal diary data were compared and condensed. Eight CNSs and 24 clinical nurse colleagues from acute care and community psychiatric nursing units voluntarily participated in the study. A four-component framework, including clinical practice, organization, education, and professional role, was adopted from nursing literature and used for categorization. The findings showed similarities of role perceptions in the clinical practice, organization, and education components between the CNSs and their nursing colleagues. Differences in role perceptions, concerns about inadequate knowledge and autonomy, and limitations in professional role are discussed.

This study was conducted to examine the knowledge of and attitudes toward sex of 178 Chinese secondary school students in Hong Kong. The data were collected using a questionnaire that comprised three parts: the Chinese version of the Mathtech Knowledge Test, the Chinese version of the Mathtech Attitude and Value Scale, and a demographic sheet seeking sociodemographic information. In general, students demonstrated a low level of sexual knowledge, especially in relation to adolescent marriage, the probability of pregnancy, and adolescent sexual activity. With regard to attitudes, students indicated positive attitudes toward importance of family and importance of birth control. Male students in comparison with their female counterparts had a higher level of agreement with premarital intercourse and the use of pressure and force in sexual activity.
