Chromosome studies at the paediatric necropsy.

The results of chromosome studies from 1193 consecutive paediatric necropsies in Edinburgh and 331 in Adelaide are given. In the Edinburgh series 51 major chromosome abnormalities were detected in 780 (6.5%) necropsies where chromosome studies were successful and in Adelaide 16 in 295 (5.4%) were found. It is suggested that chromosome studies should become an integral part of the paediatric necropsy except for deaths due to primary central nervous system lesions and trauma.

Students' assessment of paediatric teaching and their opinions 7 years later.

A prospective study of the long-term validity of student assessment of paediatric teaching began during the period 1968--70. The students gave scores to the different parts of the course in a standard questionnaire. Between 6 and 8 years later the same students were given the same questionnaire to complete. 76 of the original 92 students responded. By this time most of them were either principals in general practice, or senior registrars or consultants in hospital medicine. The 18 items in the paediatric course were given remarkably similar scores in the two questionnaires, and the popularity ratings of only 2 items had altered significantly during the 7-year interval. The doctor 6--8 years after the course seems more likely to appreciate the need for teaching about communication skills.

The training and evaluation of clinical nurse, with special reference to paediatrics and child health.

There is an urgent need to train nurses to assist with the provision of health services for children in the Republic at a clinical level as opposed to their traditional nursing role. Aspects of paediatric training and evaluation of the clinical nurse are discussed. The need for flexibility in training programmes and in their evaluation, without in any way affecting the minimum standards required by the Nursing Council and the South African Medical and Dental Council, is stressed. Steps should be taken to give recognition to the advanced and primary paediatric clinical nurse by defining her function, training and evaluation, designation and status within the health services and the community.

[Intravenous fluid therapy in paediatric surgery].

From 1956 to 1969 we adopted a generous approach pertaining to the quantity of parenteral fluid required for paediatric surgery. Since 1970 we have changed our policy, and we now give smaller quantities during surgery and postoperatively. This article presents the calculated parenteral fluid regimen as implemented for general paediatric surgery in the Tygerberg Hospital. Our reasons for this change are indicated.

Hot vs cold knife for endoscopic ablation of posterior urethral valves: a systematic review by the EAU-YAU paediatric urology working group.

INTRODUCTION: Posterior urethral valves (PUV) are the most frequent cause of congenital lower urinary tract obstruction in males. Despite early surgical ablation, up to 22% of patients develop chronic kidney disease and 11% progress to end-stage renal disease. Multiple endoscopic modalities have been described for valve ablation but the optimal technique remains uncertain. This systematic review aims to determine whether cold or hot knife ablation provides superior effectiveness for primary endoscopic treatment of PUV in a single surgical session. MATERIAL AND METHODS: A systematic search of PubMed and Embase databases was conducted to identify studies comparing cold and hot knife techniques for endoscopic ablation of PUV in children, covering all publications up to December 2025. The review was performed in accordance with PRISMA 2020 guidelines and was prospectively registered in PROSPERO (ID CRD420251180556). Original studies including patients <18 years who underwent primary valve ablation with postoperative cystoscopy or VCUG and ≥6 months of follow-up were included. Quality assessment was done using RoB 2.0 for randomized trials and MINORS for observational studies. RESULTS: A total of 1581 studies were identified, of which 26 met the inclusion criteria, comprising one randomized controlled trial, five prospective, and 20 retrospective studies constituting a sum of 1725 paediatric patients. The overall methodological quality of included studies was moderate, with marked heterogeneity in design, follow-up duration, and outcome reporting, limiting direct comparisons across series. Thus statistical analysis was not possible. Of these, 829 (48.1%) underwent cold valve ablation and 896 (51.9%) underwent hot ablation techniques. Within the cold group, most patients were treated with a cold knife (80.2%), followed by balloon dilatation (7%), the Mohan valvotome (6.5%), cold hook (5%), and, rarely, a modified venous valvulotome (1.3%). Among hot techniques, 32.8% of procedures were performed by electro-fulguration with a resectoscope, 29.4% using a Bugbee electrode, 23.8% with a hook electrode and 14% with laser-based systems. Follow-up ranged from 6 months to 22 years across studies. Single-session success rates for valve ablation ranged from 22% to 100% in the cold resection group and from 71.4% to 100% in the hot resection group. Reintervention for residual valves was reported in 0%-78% of cold cases and in 0%-28.6% of hot resections. Urethral stricture rates ranged from 0% to 11.1% after cold incision and from 0% to 23.8% after hot techniques. Reporting of postoperative outcomes such as urinary tract infection, incontinence, bladder dysfunction, vesicoureteral reflux (VUR) resolution, hydronephrosis improvement, and renal function varied widely among studies and was assessed using different methodologies. CONCLUSIONS: Both cold and hot ablation techniques for PUV achieved high single-session success rates and low complication rates. Cold resection appeared slightly safer, although this finding should be interpreted cautiously given the heterogeneity and observational nature of the available data.

Immunobiology of paediatric intracranial tumours. A preliminary report.

Preliminary findings in the evaluation of the immune response of children with primary neoplasms of the CNS, mainly medulloblastomas, are reported and discussed. A broad scheme for the monitoring of B- and T-cell-dependent immunity and of delayed hypersensitivity reactions in this type of patient is presented. The most important immunobiological findings are discussed. Special attention is given to the striking failure of the T-cell-dependent pool (currently identified by "active" RFC and blastigenesis tests) and to the remarkable decrease of hypersensitivity reactions (depressed skin-test response), both of which seem to be related to the degree of malignancy of the tumour. A very peculiar feature, i.e., the appearance of cells with natural cytotoxic activity, is dealt with in some detail. Our present knowledge concerning the immunobiology of primary CNS neoplasms is still very incomplete, but seems to suggest a possible role for immunotherapy in paediatric neurosurgery.

Sinus histiocytosis with massive lymphoadenopathy (Rosai-Dorfman disease). Clinico-pathological analysis of a paediatric case.

Histochemical and immunohistochemical studies performed in only a few cases of sinus histiocytosis with massive lymphoadenopathy (SHML) indicated that SHML cells belong to the macrophage--histiocyte system, though their exact origin is still uncertain. We analyzed the morphological, antigenic and enzymatic characteristics of the histiocyte-like cells in one paediatric case of SHML (also named Rosai-Dorfman disease). The SHML cells expressed the S-100 protein, lectins concanavalin A, peanut agglutinin and monocyte-macrophage related antigens CD 11c, CD 14, CD 33, CD 68 and LN 5. Reactivity with other anti-macrophage antibodies (MAC387, lysozyme, alpha-1 anti-chymotrypsin) was variable. The CD1a antigen was present only in scattered cells, whereas HLA-DR and the HLA-DR associated invariant chain were absent. Cytochemistry demonstrated an intense activity of acid phosphatase and non specific esterase of SHML cells. A large amount of medium sized mononuclear cells were located in the sinuses and intersinusoidal tissue. Our findings suggest that SHML cells have intermediate features between phagocytes and Langerhans cells/interdigitating reticulum cells. The heterogeneity of marker expression on SHML cells might be related to the local content of factors (e.g., cytokines), capable of modulating the phenotype of monocyted and derived cells.

Pre- and post-transplant assessment of liver function in paediatric liver transplantation.

The pre-operative risk of paediatric liver transplantation candidates (n = 41) was assessed in a prospective study by means of clinical symptoms, conventional static and liver blood flow dependent dynamic liver function tests. Nine patients died during the 365-day waiting period. The data were subjected as covariates to a survival analysis in the Cox proportional hazards model. There was a significant relationship between the results of mono-ethylglycinexylidide (MEGX) formation and ICG test and the 365-day survival rate. In the stepwise analysis, none of the remaining parameters improved the predictive ability when added to the dynamic liver function test results. The assessment of post-transplantation liver function was studied in 27 patients during the first 28 postoperative-day period. In addition, liver function was studied in a cross-sectional study 1-7 years after successful liver transplantation in children with complete or partial rehabilitation. In the early postoperative period severe organ damage was indicated by both static and dynamic liver function tests. In the later course after transplantation no deterioration of liver function measured with MEGX formation was to be observed. These findings demonstrate the usefulness of dynamic liver function tests in the pre- and post-transplant assessment of liver function.

The influence of long-term morbidity on health status and rehabilitation following paediatric organ transplantation.

Driven by the technological and immunological innovations of the past decade, paediatric transplantation has evolved quickly to occupy an important clinical role in the management of vital organ failure. With this success, the focus of clinical attention has moved progressively from an institutional to a more comprehensive community perspective, and the long-term success of transplantation has assumed greater importance in the evaluation of risk and benefit. Five-year patient survival now exceeds 90% after living donor or cadaveric renal transplantation, 70% following heart or liver transplantation, and approaches 60% at 2 years for the more developmental procedures of heart/lung and lung transplantation. Successful transplantation is accompanied by compelling evidence of improved quality of life. The earliest and most prominent gain is in physical capability, with a progressive re-establishment of social and psychological functioning compared to age-appropriate developmental norms. More than 75% of long-term recipients are in school or employed with a high rating of life satisfaction. Rehabilitation is threatened, however, by the complications of long-standing organ failure and long-term immunosuppression. These principally encompass skeletal and developmental disorders, metabolic abnormalities, cardio-vascular disease, renal dysfunction, and chronic infection or malignancy arising as a result of impaired immune surveillance. Prevention or effective management of these debilitating sequelae is a principal goal in the changing paradigm of organ transplantation for the current decade.

Transplantation--a new dimension for paediatrics.

Amazing advances have been achieved over the last 20 years in transplantation. As well as the problems of rejection and its control there are other difficulties which have to be confronted. There are shortages of donors, problems of selection for treatment and the problems of funding this expensive form of therapy. The need to make choices has to be considered and the criteria in determining choice have to be determined. Of particular concern in paediatrics are the problems that arise in relation to rehabilitation and the need to provide a multi-disciplinary approach to care. Finally, we have to remember that our enthusiasm for the possibilities of saving life and new treatments must not interfere with the basic responsibility to prevent suffering; at times the preservation of life at all costs is not justified, but in such circumstances doctors and other health care professionals have a responsibility for providing support both to the patient and to the family.

Aspects of tropical paediatrics.

Malnutrition interacting with infectious and parasitic diseases are the main causes of the appalling mortality in childhood in the tropics. The most important single safeguard against these in infancy is breast feeding and the trend now evident to abandon this is a disaster which demands urgent attention. Reasons for this trend are discussed. Efforts to control infectious diseases, other than smallpox, have had little success and the emergence and spread of dengue haemorrhagic fever in S.E. Asia have added new dimensions to the problem. Malaria is still widely prevalent in the tropics and falciparum malaria, holoendemic in much of Africa, remains a major cause of death with its most serious impact on pregnant women and children. The emergence and spread of drug resistant strains of this parasite in parts of the world is a cause for serious concern. Quartan malaria is also an insidious corruptor of health in childhood and commonly causes the nephrotic syndrome. Neonatal jaundice, often associated with G6PD deficiency, is increasing in frequency in urban areas of Africa and now constitutes a significant hazard to the newborn and requires urgent investigation. These problems in tropical paediatrics indicate the need for urgent reappraisal of our role as a profession in the affairs of the tropical developing world.

Septicaemia in paediatric intensive-care patients at the Hospital for Sick Children, Great Ormond Street.

A review of nosocomial septicaemia in paediatric intensive care in a tertiary referral setting was undertaken for a 33-month period (1988-90). This involved six units: Cardiothoracic surgery; Neonatal surgery; general medical; Renal dialysis/transplant; Haematology/Oncology and Infectious disease/Immunology. The latter two units undertake bone marrow transplantation. During the study period, 10,719 admissions were made to these areas and 624 episodes of septicaemia were documented in 464 children. The frequency of septicaemia per 100 admissions ranged from 1.5 in the Renal Transplant Unit to 17.3 in the Haematology/Oncology unit. Over 60% of all septicaemic episodes occurred in children in the Haematology/Oncology and Cardiac Units. Gram-positive organisms were responsible for 66% of episodes, Gram-negative organisms for 17% and fungi for 3%. Polymicrobial episodes accounted for 13%. Coagulase-negative staphylococci were the most frequent isolates overall (43% of episodes in pure culture, and a further 6% in combination with other organisms). Staphylococcus aureus was associated with 10% of episodes, Enterobacteriaceae with 9% and Pseudomonas spp. 6% among which environmental pseudomonads predominated. Anaerobes and Haemophilus influenzae were each isolated in less than 1% of episodes.

Results of intraocular lens implantation in paediatric aphakia.

Intraocular lenses were implanted in 16 eyes of 13 patients with congenital cataract, and visual progress was plotted using a preferential-looking technique. Initial surgery was by lens aspiration with preservation of the posterior capsule, and subsequent posterior capsulotomy without anterior vitrectomy. Poly-HEMA posterior chamber lenses were used, usually as a primary procedure but in four cases as a secondary procedure after contact lens failure. No serious complications were encountered. Most eyes achieved a very significant visual improvement, and none were worse than preoperatively. Residual refractive error was highly unpredictable, but did not exceed 6 dioptres. The importance of rigorous occlusion therapy is stressed. With close follow-up, this procedure offers an effective and safe method for the correction of unilateral paediatric aphakia, and, in selected cases only, for bilateral aphakia.

The paediatric syndrome of traumatic myelopathy without demonstrable vertebral injury.

Three detailed case histories are added to those previously published in the literature and from the evidence now available a proposal is made that a paediatric syndrome of traumatic myelopathy without demonstrable vertebral injury be recognised as a definite clinical entity. The mechanisms of injury, evolution, patterns of paralysis and pathological evidence are discussed. The conclusion is drawn that no form of treatment yet known can influence the prognosis in this syndrome.

Paediatric empyema thoracis in Zaria, Nigeria.

From 1977 to 1986 at the Ahmadu Bello University Hospital in Zaria, the diagnosis of empyema thoracis was made in 150 children representing 0.35% of all paediatric admissions. Empyema was a complication of pneumonia in 98 of 100 cases reviewed, of whom 70 were 3 years old or younger. There was no sex or side preference. Fifty-nine patients were severely ill on admission, with a mean symptom duration of 21 days. In many of them, anaemia, protein-energy malnutrition, measles and gastro-enteritis were present as associated illnesses. Staphylococcus aureus was the most frequent bacterial isolate (39%), of which 83% of the cultures were sensitive to cloxacillin. Adequate rehydration, systemic antibiotics and tube thoracostomy drainage performed in 80 patients were more successful than repeated needle aspiration. Fourteen of the children died, six absconded and 80 were discharged home.

Visceral and cutaneous leishmaniasis in an European paediatric population.

Six children with leishmaniasis, aged 10 months to 10 years, were treated in the Paediatric Department. Four patients had visceral leishmaniasis (kala-azar): diagnosis was based on bone marrow examination and therapy consisted of a combination of Glucantime and Lomidine. The remaining two children had cutaneous leishmaniasis: diagnosis was made by skin biopsy and the patients were treated with Glucantime alone. In all children, serology was clearly positive at the time of the diagnosis and all patients improved. The only side effects were cough associated with fever in one child, and supraventricular premature beats in another one. They were ascribed to Glucantime, and proved reversible after discontinuation of the treatment.

The magnitude of air admixture with a jet device in paediatric anaesthesia.

The admixture of air in inspired gas with a paediatric insufflation system based on a gas jet has been investigated. During anaesthesia with spontaneous ventilation 1% of air per kg body weight was found in tracheal gas samples. A venturi effect was virtually absent even at high jet flows, which suggests that artificial ventilation prevents air admixture.
