Parents Expectations and Child Rearing Practices in Hong Kong

This paper reports on some aspects of interactions of parents with their children in Hong Kong. In particular some of the child rearing practices and their educational implications are presented. The study is an interview based research project in which 130 parents of children between the ages of birth-12 years gave their views about a range of issues including what they want for their child (expectations), how they discipline their child, who the parent goes to for advice on child rearing, how much homework the child does each day. The paper sheds some light on the difficult task of rearing children in a situation where traditional family practices are changing and where pre-schools and schools work in very formal ways.     

Ethics and Society: Filiation in assisted reproduction: potential conflicts and legal implications

Filiation, or a person's parentage, is one of the major componentsof someone's identity, often with important implications forthat person's welfare in social and personal terms. Fertilityspecialists are enjoined to consider the welfare of the child,and this is a legal requirement in assisted reproduction techniquesin the UK. This paper is in three parts, discussing some ofthe potential problems regarding filiation of the prospectivechild born of assisted reproduction techniques, in relationto the use of gametes and embryos. The first two parts concentrateon the status of children born as a result of treatment givenposthumously, and on filiation problems associated with donationof gametes or embryos, and surrogacy. The third part comparesBritish and French legislation with special regard to the welfareof the child, as well as underlining the common trends and principlesenunciated in both legislations. This is particularly appropriateat a time when the European Society for Human Reproduction andEmbryology is about to issue ethical guidelines in assistedreproduction, and when both the Council of Europe and the EuropeanCommission have commissioned studies on the implications ofthe assisted techniques, including those concerning status ofthe potential children.

Lymphocyte subclasses and function in patients with optic neuritis in childhood with special reference to multiple sclerosis

Ten patients with childhood optic neuritis (5 with a single attack of ON and 5 with later MS) were studied at various stages of the disease. Lymphocyte count and function were analysed in the peripheral blood of all patients, 3 repeatedly, and in one they were also analysed in the CSF. T-lymphocytes counts were normal in all but 2 MS cases who had high counts. In acute stages the T4/T8 ratio were high in 1/3 determinations, in recovery low in 2/2 determinations, and in stable stages normal in 6/8 determinations. Lymphocyte function, measured by PHA, ConA and PWM stimulation, was normal in all but one. One patient showed significantly higher T-cell percentages and a high number of stimulated lymphocytes in CSF but a lower count of suppressor cells than in the blood. We found no abnormalities specific to MS nor to childhood MS or to disease activity stage. Rather than peripheral blood, it would seem more worthwhile to study CSF to clarify the pathogenesis of ON and MS.     

Abnormalities in visceral evoked potentials from the anal canal in children with chronic constipation

The integrity of the sensory nervous system in the anal canals of chronically constipated children was investigated using evoked potential techniques examining cerebral and spinal evoked potentials from the lower extremities and anal canal. Stimulation of the posterior tibial nerve produced no significant difference in the parameters of spinal and cerebral evoked potentials between 18 controls and 12 chronically constipated chidren. However, stimulation of the anal canal resulted in evoked potentials related to the age and/or consciousness level of the control children. Reproducible cerebral responses were obtained only from nine of these control children, all aged over 4 years, who were examined while awake without sedatives. A typical response was characterized by a polyphasic wave occurring with an onset latency of 79.4± 27.7ms (mean ±SD). In the 12 chronically constipated children, the 5 sedated patients examined while asleep did not show any reproducible potential, as in the controls. However, in the remaining 7 children examined while awake, the occurrence of the anal canal evoked potential was significantly reduced, and only two exhibited a cerebral response. These findings suggest that rectal mucosal perception of the intraluminal stimuli might be disturbed in some children with chronic constipation.

A prospective study of allergy development in 158 children and 128 adults with new extensive exposure to furred animals

BACKGROUND: There is still controversy over whether exposure to furred animals increases or decreases the risk of developing sensitization and allergic symptoms to such animals, and there is a need for further knowledge on this subject. OBJECTIVE: The aim of this study was to follow allergy development in relation to new extensive exposure to furred animals in adults and children. METHODS: A total of 286 individuals, 128 parents and 158 children, were recruited from 68 families who intended to buy a dog or a cat, or where one child of the family intended to start riding a horse. Subjects were examined before the new allergen exposure and once a year thereafter for 5 years, in all at six occasions, and they also completed questionnaires covering allergy symptoms. Serum IgE antibodies to cat, dog and horse were determined each year, and fur allergens from beds and living rooms were analysed. RESULTS: Two-hundred and fifty-six study subjects remained for evaluation, 37 of whom showed signs of allergic sensitization at the start of the study. Four children (11%) in this pre-sensitized group developed IgE antibodies to their new animal and six (16%) to another animal. Among the 219 participants who were not sensitized when entering the study, one male adult (0.4%) developed a sensitization to his new animal, and nobody developed sensitization to other animals. Pre-sensitized individuals had significantly more allergic symptoms at the study start, but the symptom scores did not change over time. CONCLUSIONS: When the first year of a human's life has passed, we have no strong evidence to recommend avoidance of a domestic animal in order to prevent new allergy development, even if there are known allergies in the family or if the individual is sensitized and has allergic symptoms to another allergen. Five years exposure to new fur allergens does not seem to influence sensitization to these animals in either sensitized or non-sensitized children and adults.     

Noonan syndrome associated with central giant cell granuloma

We report a case of Noonan syndrome associated with central giant cell granuloma. The patient was a 101/2-year-old boy with the chief complaint of proptosis of the right eye. He also had various malformations such as short stature, webbed neck, pectus excavatum, cubitus valgus, pulmonary valve stenosis and patent foramen ovale, a characteristic face appearance and cryptorchidism and so on. Chromosome analysis showed a 46, XY karyotype. A computed tomographic scan and magnetic resonance imaging showed a mass originated from the lateral wall of the right maxillary sinus. The patient underwent Caldwell-Luc operation. Histological examination of the mass showed the characteristics of central giant cell granuloma. This case report describes a patient with the features of the recently described Noonan-like/multiple giant cell lesion syndrome.
