Spectrum of clinical presentations of vein of Galen aneurysm

Aneurysm of the vein of Galen is a rare intracranial vascular malformation. It is known to have diverse manifestations and varying severity. Four cases with different modes of presentation and outcome are reported. A mortality of 50 per cent was encountered. Among the survivors, one had neurologic sequelae whereas the other had attained age-appropriate developmental milestones. The former was a rare case of spontaneous thrombosis of the aneurysm while the latter was a boy who underwent therapeutic embolization.     

Outcome of the Treatment of Inborn Errors of Metabolism

The use of specific dietary restrictions, cofactor administration, mobilisation of insoluble substances, environmental modifications, product replacement and selective enzyme inhibition are now established for the treatment of some inborn errors of metabolism. There is no generally accepted application for enzyme administration, cytopharmacology (manipulation of the cytoskeleton) or for cell transplantation except for bone marrow transplantation in disorders where the bone marrow is primarily at fault. The other uses of bone marrow transplantation which have been proposed require further evaluation. Results of recent research suggest that the scope of this approach is gradually being widened. There is also scope for development in the field of organ transplantation taking advantage of recent technical¹ and immunological progress. The treatment of inborn errors of metabolism by genetic modification is not yet on a practical clinical level; more laboratory and animal studies are needed before this can be attempted in man. Adenosine deaminase deficiency appears to be the disease in which this will be first attempted using a retroviral vector to insert the gene into the genome of pluripotential bone marrow cells.

Treatment of retinopathy of prematurity

Retinopathy of prematurity is a potentially blinding disorder of premature infants. Retinal ablation of the avascular retina originally described using cryotherapy but now most commonly undertaken with laser photocoagulation, reduces the unfavourable structural outcomes and improves the functional visual acuity outcome. The CRYO-ROP study showed the long-term benefit of treatment of threshold disease compared with no treatment, however even with cryoablation 44.4% of treated eyes had a visual acuity of 6/60 or worse at 10 year follow-up. The ETROP study of earlier treatment for high-risk pre-threshold disease, rather than treatment at threshold, has shown that pre-threshold treatment of type 1 disease produces a significantly improved outcome. Despite treatment some infants develop retinal detachment for which various surgical treatments have been described, although not always with a good functional outcome. Future treatment modalities may include the use of anti-VEGF therapies.

The influence of patency of the vaginal process on the efficacy of hormonal treatment of cryptorchidism

To investigate the effects of patency of the vaginal process (processus vaginalis testis) on the efficacy of hormonal treatment of cryptorchidism, we carried out a blind, controlled, prospective study in which all patients underwent inguinal herniography. The sample comprised 310 boys with true cryptorchidism (244 unilateral, 66 bilateral) and without symptomatic hernia/hydrocele or other pathologies. Patient age ranged from 8 months to 11 years 5 months. All patients were treated with human chorionic gonadotropin (twice-weekly intramuscular injections for 5 weeks; total dose 2500 lU for patients less than 1-year-old, 5000 IU for 1- to 6-year-olds, 10000 IU for 6- to 11-year-olds). Following treatment, 37% (139/376) of the testes descended. The incidence of descent was highest for testes initially in caudal positions. Considering only non patent (i.e., normal) vaginal processes, the incidence of testis descent was 49.5% (139/281); none of the 95 testes associated with a patent vaginal process descended in response to hormone treatment.

The sound of silence: evolution of the object in the relationship of parents of two twins

This paper derives from a longer dissertation submitted for an MA in Psychoanalytic Observational Studies. Aspects of thinking about silence and significant contributions to the psychoanalytic and psychological research history are discussed in depth as a prologue to the discussion of a case in which the parents of twins were seen by the author in an attempt to encourage more listening as well as talking between the father and mother and with their children. Silence is seen as a significant internal sounding board through which the individual may listen to what others say, to himself, and to enable the birth to new thoughts. The review in depth of the literature on silence is applied to therapeutic work undertaken by the author with a couple one of whose twins was in psychotherapy. The author connects the significance of the absence of silence and the absence of toleration of silence in the couple with absence of the experience of being taken in, contained, and of the experience of being heard and listened to by internal parents.     

Reliability of subjective estimates of exercise capacity after total repair of tetralogy of Fallot

Sixty-nine patients (age 10 × 3.5 years, median 9.7 years) operated on for tetralogy of Fallot, underwent excercise testing 5.1 × 2.5 years after total correction. Aerobic capacity was assessed by the ventilatory threshold method. After the exercise test, parents completed a validated standardized questionnaire to evaluate the habitual level of physical activity of their child. They were then asked to place their child into one of three groups, describing their child's activity level, compared to normals (below average, average and above average). In the average and above-average groups, 73% and 65% of the patients were misclassified when compared to objective exercise testing. However, in the below-average group, no misclassifications were found. Subjective estimates of activity level, and consequently exercise tolerance, were poorly associated with objective measurements of exercise performance in these patient groups. Our results question the reliability of self-reported estimates of physical activity level and consequently exercise capacity in children after surgical correction of tetralogy of Fallot.     

Epidemiology of respiratory distress of newborns

The present prospective study was conducted to find out the incidence, etiology and outcome of respiratory distress (RD) in newborns. All newborns (n=4505), delivered at this hospital over a period of 13 months, were observed for respiratory problems. Relevant antenatal, intranatal and neonatal information was noted. Cases were investigated for the cause of respiratory distress and followed up for the outcome. The overall incidence of RD was 6.7% Preterm babies had the highest incidence (30.0%) followed by post-term (20.9%) and term babies (4.2%). Transient tachypnea of newborn (TTN) was found to be the commonest (42.7%) cause of RD followed by infection (17.0%), meconium aspiration syndrome (10.7%), hyaline membrane disease (9.3%) and birth asphyxia (3.3%). TTN was found to be common among both term and preterm babies. While Hyaline membrane disease (HMD) was seen mostly among preterms, and Meconium aspiration syndrome (MAS) among term and post-term babies. Overall case fatality ration for RD was found to be 19%, being highest for HMD (57.1%), followed by MAS (21.8%) and infection (15.6%). Our results indicate that RD is a common neonatal problem. TTN accounts for a large proportion of thhese cases. MAS and infection also contribute significantly and are largely preventable. Without adequate ventilatory support HMD and MAS carry high mortality.     

Evaluation of the Efficacy of Treatment of Kawasaki Disease before Day 5 of Illness

We evaluated the efficacy of treating Kawasaki disease earlier than Day 5 of illness with a standard dose of immunoglobulin and aspirin. We performed a case–control study of patients with Kawasaki disease admitted to Princess Margaret Hospital from 1994 to 1999. Patients with pretreatment coronary aneurysm or those treated after day 10 of illness were excluded. All patients received immunoglobulin (2 g/kg) and aspirin (80–100 mg/kg/day) until fever subsided for 48 hours. Immunoglobulin retreatment was given for persistent fever 48 hours after the first dose of immunoglobulin or recrudescent fever. The case group consisted of 15 patients who received treatment earlier than day 5 of illness, and the control group consisted of 66 patients who were treated on or after day 5. Patients sex, age, duration of posttreatment fever, need for additional immunoglobulin, and coronary artery status were noted. Treatment efficacy was assessed by the duration of posttreatment fever and the prevalence of coronary artery aneurysms. Eighty-one patients were included in this study. There were 15 patients in the case group and 66 in the control group. No significant difference was noted in age and sex between the case and control groups. Thirty-three percent (5/15) and 8% (5/66) of the case and control groups, respectively, had persistent/ recrudescent fever 48 hours after the first dose of immunoglobulin that required retreatment (p = 0.017). Thirteen percent (2/15) and 5% (3/66) of the case and control groups, respectively, had coronary aneurysms (p = 0.158). Treatment of Kawasaki disease before day 5 of illness was associated with persistent/recrudescent fever that required retreatment. However, there was no significant increase in the prevalence of coronary aneurysm if retreatment was given.
