Growth status of Jordanian schoolchildren in military-funded schools.
OBJECTIVE: To study the growth status of Jordanian boys and girls in comparison with the Centers for Disease Control (CDC) growth charts. DESIGN: Cross-sectional study. SUBJECTS AND DATA COLLECTION: A total of 5826 boys and 1414 girls, aged 6.5-17.5 y, were included in the study. Height and weight were measured. Body mass index (BMI) was calculated as weight (kg) divided by the square of the height (m). Socioeconomic data were collected using a structured questionnaire. RESULTS: The height-for-age values fluctuated between the 5th and 10th percentiles of the CDC for both sexes, and then after the age of 8.5 and 14.5 y for boys and girls, respectively, values were just above the 10th percentile. The body weight-for-age values were just above the 25th percentile for boys and fluctuated between the 25th and 50th percentiles for girls; then after the age of 14.5 and 12.5 y for boy and girls, respectively, values fluctuated between the 25th and 50th percentiles for boys and just above the 50th percentile for girls of the CDC values. BMI values for boys were just above the 50th percentile of the CDC and for girls values fluctuated between the 50th and 75th percentiles until the age of 13.5, then values matched the 75th percentile of the CDC. CONCLUSION: The height of Jordanian children ranges from the 5th to the 10th percentile of the CDC reference values during schools years. Girls have a tendency toward obesity after puberty.

Autoregressive moving average modeling for finger tapping with an external stimulus.
We report the Autoregressive Moving Average (ARMA) structures of interresponse interval and interstimulus interval in rhythmic finger tapping and how tapping schemes arise from these structures. The interstimulus interval is chosen to be a metronome cue slightly perturbed from its periodic mode by a zero-mean sine-wave modulated sequence. These metronome sequences were chosen to follow an exact Autoregressive model of the third order and are generated using metronome interval durations of 400, 500, and 600 msec. At each frequency, four different perturbation rates were presented to seven subjects: 1, 3, 5, and 7% of the base interval. Synchronization error, i.e., tap-to-beat phase deviations, induced by these ARMA models are stable and thus were bounded. This framework is useful in characterizing the relationship between motor control variables, interresponse interval, synchronization error, and interstimulus interval. Also, several known models can be easily derived and analyzed in this setting.

A new technique for fibreoptic intubation in children.
We describe a technique involving the use of a laryngeal mask airway, fibreoptic bronchoscope and a guide wire to manage the intubation of a child who was known to be a difficult intubation. The technique is simple, atraumatic, permits the use of an adult bronchoscope for infants and children, and allows control of the airway and ventilation throughout the period of intubation.

Depth of epidural space in children.
We have studied the depth of epidural space in 586 children who had lumbar epidural block as part of their anaesthetic management. The mean depth of epidural space in neonates was 1 cm (SD 0.2, range 0.4-1.5 cm). The depth of epidural space in older infants and children correlated significantly with age and weight with regression equations of depth (cm) = 1 + 0.15 x age (years) and depth (cm) = 0.8 + 0.05 x weight (kg) respectively.

Comparison of automatic oscillometric arterial pressure measurement with conventional auscultatory measurement in the labour ward.
We have compared two non-invasive methods of arterial pressure (AP) measurement used in labour wards: an automatic oscillometric measurement obtained by Dinamap 1846, and a conventional auscultatory measurement obtained by midwives. A total of 369 AP measurements were recorded, involving 28 normotensive and hypertensive pregnant women during labour, with or without extradural analgesia. Compared with the midwife group, the Dinamap group had a greater systolic AP, by 2.7 mm Hg (P < 0.01) and smaller diastolic AP, by 9.8 mm Hg (P < 0.01). The correlations between the two methods were highly significant, but the limits of agreement were relatively wide for both systolic and diastolic AP measurements. We conclude that a clinically important difference exists in diastolic AP measurements. Dinamap diastolic AP must be corrected using a regression equation, or simply by adding 10 mm Hg, before being compared with the available normal and hypertensive AP values.

Isoflurane in labour.
A comparison of the analgesic efficacy of Entonox (50% nitrous oxide in oxygen) and Entonox with 0.2% isoflurane was made in 18 consenting mothers during the first stage of labour. The inhalational gases were self-administered during contractions over a 3 h study period using a standard Entonox demand valve and breathing system. Isoflurane 0.2% was added from an Ohmeda Isotec drawover vaporizer and the inspired concentration of isoflurane was analysed continuously using a Datex Ultima analyser. Linear analogue scores for pain were significantly lower (p < 0.001) during the Entonox-isoflurane administration compared with Entonox alone. Drowsiness was not a clinical problem and there was a high acceptance rate for Entonox-isoflurane inhalational analgesia during labour.

Chronic diarrhoeal diseases in adults (a preliminary report).
The relationship of chronic diarrhoeal diseases in adults on socio-economic condition, parasitic infestation and degree of anaemia have been investigated. The disease was more prevalent in poor socio-economic group of people. Most of the patients had mixed parasitic infestations. Anaemia was present in all the cases. Difference in the degree of anaemia was not significant amongst the patients having either Ascaris or hookworm infestation.
