    Notes: We describe a first-order gradiometric dc superconducting quantum interference device (SQUID) and its incorporation into a first-order directly coupled single-layer gradiometer. The gradiometric SQUIDs were fabricated from a single layer of YBa2Cu3O7, with a silicon dioxide insulating layer and a gold crossover structure. For several gradiometric SQUIDs, with estimated inductances of order 67 pH, we measured parasitic effective areas in the range 1–2 μm2, approximately two orders of magnitude lower than for conventional narrow linewidth SQUIDs of similar inductance. For a single-layer gradiometer incorporating a gradiometric SQUID, we measured a parasitic effective area of 95 μm2. We demonstrate that for this device, the SQUID itself makes a negligible contribution to the overall parasitic effective area. We show that the improved balance leads to better performance in an unshielded environment. © 2000 American Institute of Physics.

    Selective bronchial intubation for acute post-operative atelectasis in neonates and infants (1988)
    Springer
    Pediatric radiology 18 (1988), S. 494-496

    Notes: Abstract Selective bronchial intubation and lavage under fluoroscopic control was performed in 10 surgical neonates and infants to clear lobar atelectasis, after standard physiotherapeutic techniques had failed. Full re-expansion of the lung was obtained in all cases. The indications and techniques of selective bronchial intubation and lavage are described. This manoeuvre can be recommended in early postoperative atelectasis in neonates and infants if non-invasive measures have failed.

    Ultrasonic features of pyogenic and amoebic hepatic abscesses (1989)
    Springer

    Topics: Medicine
    Notes: Abstract Pyogenic liver abscesses are not infrequent in some developing countries. Amoebic abscesses may also occur in endemic areas and differentiation may be difficult. The ultrasonic data of proven cases of both conditions were compared and we are now more more confident in predicting the aetiology of these lesions.

    The deadly vomit: malrotation and midgut volvulus (1987)
    Springer

    ISSN: 1437-9813
    Keywords: Malrotation ; Midgut volvulus ; Children

    Topics: Medicine
    Notes: Abstract 137 cases of malrotation and midgut volvulus seen over a 28-year period are reviewed to emphasize the patterns of clinical presentation. Although 62% presented as neonates, 20% were over 1 year of age. Vomiting was the sympton of paramount importance in 97% but was not initially bile-stained in 20%. Sixteen percent had diarrhea as a major symptom. Abdominal pain occurred in 96% of patients over 1 year of age. Clinical signs were not apparent in most cases until gut infarction had occurred. Radiographic examination of the abdomen was considered normal in more than 20%. Barium meal was the contrast examination with most accuracy and should be diagnostic if correctly interpreted. The significant mortality (19%) in all age groups was invariably related to delay in presentation or diagnosis.

    Radiation enteritis in children (1988)

    Notes: Abstract Six children with intestinal radiation injury following cancer therapy are presented. The radiation dose varied from 3500 rads to 6600 rads. Symptoms of radiation enteritis took from 3 weeks to 3 years to develop. All patients received concomitant chemotherapy. Incomplete bowel obstruction was the most common presenting feature (four cases); five came to laparotomy. Simple adhesiolysis was successful in two cases; two children required more extensive surgical manoeuvres (small-bowel bypass and bowel resections). All are alive and well 4 to 13 years following therapy although five have other radiation effects. Radiation injury to the bowel and its management are discussed.

    Liver abscess in childhood (1988)

    Topics: Medicine
    Notes: Abstract Seventy-five children with pyogenic liver abscess are reviewed and compared with 21 with amoebic liver abscess occurring within the same 13-year period (1974–1986). Both groups presented with a similar syndrome complex. Noted differences were age at presentation (pyogenic: mean age 4.5 years and amoebic: mean age 2 years), the association of dysentery in 43% of the amoebic group, and the 76% incidence of Ascaris infestation in the pyogenic group. Predisposing disease was uncommon. Diagnosis was often delayed, which led to 4 deaths in the pyogenic group (overall mortality 4%). Diagnosis was confirmed with ultrasound or nucleotide liver scan. Non-operative management with antibiotics and metronidazole was successful in 37% of pyogenic and 43% of amoebic abscesses. Laparotomy and open drainage was performed for clinical evidence of peritonitis or failure to improve within 48–72 h of commencing therapy. There was no operative mortality and little morbidity in both groups.

    Pharmacologic control of gastro-esophageal reflux in infants with cisapride (1987)

    Notes: Abstract Autonomic receptors in the upper gastro-intestinal tract permit pharmacologic manipulation of esophageal and gastric function. A new non-anti-dopaminergic, non-cholinergic, prokinetic agent, cisapride, was evaluated to determine it's efficacy in controlling gastro-esophageal reflux (GER) in infancy. Forty infants, mean age 6.5 months, were studied and their response to therapy determined by continuous measurement of lower esophageal pH over a 36-hour period. Five parameters were assessed in the erect, supine, and prone positions, both before and during short-term cisapride therapy. The drug was effective in reducing GER in 86% of the infants studied. Those infants who had a poor overall response to therapy could be identified retrospectively by the lack of improvement in esophageal acid clearance and frequency of reflux episodes; anatomic abnormalities were present in the majority of this subgroup. Cisapride is considered to be effective in the short-term treatment of primary GER of infancy, and a more prolonged assessment is indicated.
