The effect of euthyscope- and occlusion therapy in cases of convergent strabismus. Comparative, prospective examinations (author''s transl)]

1. 63 children with strabismus and amblyopia (average age 7 years) were chosen at random to be treated either with occlusion or with the Euthyscope followed by occlusion. No significant difference was apparent after comparison of both forms of treatment. 2. Six more children were occluded for several months without success and were then treated for two months with the Euthyscope followed by further occlusion. In four of these cases pleoptic treatment proved to be temporarily successful. 3. In addition, 14 children with microstrabismus and amblyopia, and 17 children with amblyopia ex anisometropia showed a distinct improvement of the visual aciuty after occlusion. An 18-year-old patient with microstrabismic amblyopia achieved normal visual acuity. 4. Euthyscope treatment was used in amblyopic patients who had lost their good eye. In the case of an 18-year-old patient the distant visual acuity increased to 0.6. The increase in the near vision and the speed of reading continued to improve for several years. 5. Papilla-Macula-Relationship: 47 amblyopes were compared with 8 anisometropic and 16 microstrabismic patients as well as with 32 normal subjects. In these groups no significant difference in the papilla-maculadistance was apparent. 6. Refraction: In amblyopic eyes there were no significant refractive errors between fixing and non-fixing eyes. Conversely, in patients with microstrabismus and those with anisometropic a significant difference was found.     

Sonographic determination of the thickness of the peritoneum in healthy children and paediatric patients on CAPD

BACKGROUND: Prolonged peritoneal dialysis and frequent episodes of peritonitis lead to structural changes and thickening of the peritoneum. Ultrasonography investigations may provide the opportunity to detect morphological changes early, but no systematic investigations have been performed yet. METHODS: Normal values of peritoneal thickness were obtained by systematically examining 131 healthy children (0-15 years) by ultrasound. Parietal peritoneal thickness was best measured at the sternal-umbical line distal from the xiphoid. Growth charts with 95% intervals were prepared. The data of 26 patients with end-stage renal failure (5-18 years) were compared to those of the normal children. RESULTS: The variation coefficient for the consecutive measurements was only 5%, interobserver error was approximately 7%. Whereas gender did not have any influence, peritoneal thickness was significantly correlated to age, weight and most obviously to height (r = 0.81; P<0.001). Children treated only by haemodialysis had normal values, while an increased thickness, loss of movement, and adhesion of the two peritoneal layers were found in children on CAPD. These changes were only noted in patients who had a history of peritonitis. CONCLUSION: Ultrasound examination is a simple, noninvasive and precise method to measure the peritoneal changes in children on CAPD.     

Spread of HIV-1 to children in Cambodia

Beginning November 1, 1995, children under 5 years of age, who were admitted to Kantha Bopha Hospitals and who were suspected tuberculosis cases, were screened for human immunodeficiency virus 1 (HIV-1) using enzyme-linked immunosorbent assay (ELISA). By January 31, 1997, 9026 children, 83% of the under 5-year-olds admitted, had been tested; 290 (3.2%) were positive. Serum samples from 205 children of the 236 seropositive children under the age of 18 months were tested for p24 antigen; 51 (25%) were positive. Mothers of 173 of the seropositive children were tested for antibodies to HIV; 170 were positive, which suggests that the main mode of acquisition of HIV-1 in the children was vertical transmission. If HIV-1 infection occurred only in the 54 seropositive children older than 18 months and in the 51 children younger than 18 months with detectable p24 antigen, the calculated prevalence of HIV-1 in children under 5 years old who were suspected of having tuberculosis when admitted to Kantha Bopha Children's Hospitals would be 1.2%. If the 17% not included in the test were all negative, the prevalence would be 1%. This is an underestimate because some of the children not tested could be positive and because some of the children tested had indeterminate HIV status. HIV testing was extended to all children admitted to the hospital; 715 were younger than 5 years of age, 596 of whom were suspected of having tuberculosis, and 119 of whom were not. The seroprevalences for the 2 subgroups were 3.2% and 0.8%, respectively. None of the 369 older children was seropositive. In 1996, the World Health Organization estimated a seroprevalence of 1.97% in adults 15-49 years old in Cambodia, the highest among Asian countries. The blood bank at Kantha Bopha found 211 (6.6%) HIV-1 seropositives among 3197 donors in 1995 and 211 (7.5%) among 2834 donors in 1996. Similar figures were seen at the National Transfusion Centre in Phnom Penh. A 1996 survey in Cambodia found an HIV-1 seroprevalence of 40.9% in prostitutes and 1.7% in pregnant women. The vertical transmission of HIV-1 to children may increase because the virus appears to have been introduced recently to Cambodia; this is indicated by lack of seropositivity in children older than 5 years of age.     

Clinical predictors of HIV-1 infection among preschool children in Dar es Salaam, Tanzania

Seroprevalence of HIV-1 infection was determined in children aged between eighteen months and five years, attending maternal and child health (MCH) clinics in Dar es Salaam, Tanzania. A total of 889 children were eligible for the study, however seven children could not be enrolled because their mothers/guardians absconded and blood could not be drawn from 21 children due to refusal of mothers/guardians and from another 12 children due to technical reasons. Therefore, the participation rate was 95.5%. Of the 849 children screened, 14 (1.65%) were found to have IgG anti HIV-1 antibodies in their sera. The main clinical features found in children with symptomatic HIV-1 disease were weight loss, generalized lymphadenopathy, recurrent fevers, and prolonged diarrhoea. The utility of clinical features suggestive of HIV-1 infection (according to CDC classification) in identifying HIV-1 infection in children was evaluated and found to have high sensitivity (100%), specificity (96.9%) and negative predictive value (100%), but a low positive predictive value (35%). Marked variations in progression to symptomatic phase were noted, whereby some relatively young children had progressed to symptomatic phase (CDC class P-2A), while some older children were still in the asymptomatic stage (CDC class P-1 C). None of the symptomatic HIV-1 infected children presented with neurological disease, severe opportunistic infections, or malignancies. Although reduced mid-upper arm circumference and weight-for-age were associated with HIV seropositivity, these clinical parameters had low positive predictive values compared to the CDC classification.     

Specific extreme behaviors of postinstitutionalized Russian adoptees.

Behavior problems reported by parents on the Child Behavior Checklist (Achenbach & Rescorla, 2001) were studied in 316 children adopted from social-emotionally depriving Russian institutions as a function of age at adoption (18-month cutoff), age at assessment (6–11 and 12–18 years), and gender. Children adopted after 18 months had higher problem scores predominately when assessed at 12–18 years. Although most children had no behavior problems, 59.0% of later adoptees assessed in adolescence had at least 1 subscale score and 48.7% had 2 or more subscale scores in the clinical/borderline range. A factor analysis of items that significantly related to age at adoption for older children revealed 1 broad factor, encompassing different antisocial behaviors, social difficulties, and withdrawal. These results may suggest a somewhat broader deficiency produced by orphanage experience beyond the first 18 months of life that underlies a range of behavioral problems displayed later.

Are serum human chorionic gonadotropin clearance curves of use in monitoring methotrexate treatment in cervical pregnancy?

Children with biotinidase deficiency usually exhibit symptoms at several months to years of age. We describe four children who had symptoms later in childhood or during adolescence; they had motor limb weakness, spastic paresis, and eye problems, such as loss of visual acuity and scotomata, rather than the more characteristic symptoms observed in young untreated children with the disorder. These older children each have different mutations, but they are the same as those of children who have exhibited symptoms at an early age. Biotinidase deficiency should be considered in older children who suddenly experience limb weakness and/or spastic paresis and eye symptoms.     

Human group C rotavirus in children with diarrhea in the Federal District, Brazil

BACKGROUND: A family history of atopy is a poor predictor of sensitization to inhalant allergens and allergic disease during childhood. We recently identified early sensitization to food allergens, especially hen's egg, as a valuable predictor of subsequent sensitization to inhalant allergens. OBJECTIVE: (1) Whether prediction will be improved by in vitro allergy tests at 1 year of age in combination with family history and medical history data. (2) Comparison with the capacities of in vitro tests to predict sensitization to aeroallergens. METHODS: Of an observational birth cohort study (MAS) 49 children who were sensitized to inhalant allergens at 5 years of age and 116 non-sensitized controls were included in the present study. For the prediction of sensitization to inhalant allergens the following prognostic factors were evaluated: atopic family history (FH), atopic dermatitis (AD) during the first year of life, two in vitro allergy tests for specific IgE to common food allergens at 1 year of age (fx5 [Pharmacia] and single allergen specific tests (sIgE) for four allergens) and 'high' total serum IgE, defined by three different cut off points. RESULTS: The combination of medical history data and laboratory tests resulted in the best predictive discrimination. The positive predictive values (PPV) were higher if sensitization to food was detected by single allergen specific tests (PPV: 66%/75%/100% corresponding to the three evaluated risk groups) than by the qualitative fx5 (PPV: 46%/65%/100%). The negative predictive values were equal for both tests (69 and 92% for the two low risk groups). High total serum IgE had low predictive capacity. CONCLUSION: During infancy the prediction of sensitization to inhalant allergens should be based on medical history data and allergy tests determining sensitization to food allergens. The in vitro tests improve the predictive discrimination, but the individual risk profile of the child must be considered for a reliable and valid prediction.     

Radiographic imaging requirements following ventriculoperitoneal shunt procedures

The requirements for radiographic imaging of the ventricles after a ventricular shunt procedure are not well defined. At British Columbia's Children's Hospital, the standard protocol included an ultrasound examination or CT scan at 6-8 weeks postoperatively, and a delayed CT scan at 6 months to 2 years, with additional scans only if the patient had symptoms of shunt malfunction. This study was performed to determine if the delayed scan could be omitted without compromising patient care. The study comprised 86 children with ventriculoperitoneal shunt operations, who had early CT scans or ultrasound examinations less than 20 weeks postoperatively, delayed postoperative CT scans between 20 weeks and 2 years, and who were asymptomatic at the time of these radiographic studies. In 39 of the 86 patients a change in ventricular size occurred between the early and delayed imaging studies, and in these patients the delayed scan was felt to be required. In patients in whom the early imaging study was done at more than 12 weeks postoperatively, and probably in patients with small ventricles preoperatively, there was no added information gained by doing a delayed scan. It is concluded that a radiographic examination of ventricular size at 12 weeks after a shunt operation may provide an adequate baseline study. If the early postoperative radiographic study is done less than 12 weeks after surgery, we would advise that in asymptomatic patients, with the exception of patients with very small ventricles preoperatively, a CT scan be repeated at a later date to obtain an appropriate baseline assessment of ventricular size for the future.     

Memory for medical emergencies experienced by 1- and 2-year-olds

Children (13-18 months, 20-25 months, and 26-34 months) who had experienced trauma injuries were recruited in a hospital Emergency Room and subsequently interviewed about them within days (if verbal) and after 6, 12, and 18 or 24 months. The youngest children demonstrated little long-term verbal recall, whereas a few children in the intermediate group, who could not narrate about past events at time of injury, could verbally recall the target events 18 months later. Most of the oldest children, who had narrative skills at time of injury, demonstrated good verbal recall 2 years later. Illustrative case histories were described. Accuracy of recall was low for the youngest children, and although the majority of older children's recalled information was accurate, there were still many errors.     

Do women who undergo further investigation for breast screening suffer adverse psychological consequences? A multi-centre follow-up study comparing different breast screening result groups five months after their last breast screening appointment

BACKGROUND: In 1995-1996 about 53500 women aged 50-64 attending for routine breast screening were called back for further investigation after an initial mammogram. Even when women were found to be clear after further investigation, significant adverse psychological consequences (PCs) can remain one month later. This follow-up study investigates whether residual emotional effects persisted five months after women received a clear result. METHODS: Women who had previously completed a questionnaire one month after their last breast screening appointment, at which they had a clear result, were invited to complete a further postal questionnaire four months later (five months after their last appointment). We compare women who received a clear result after assessment without fine needle aspiration cytology (FNAC), after assessment with FNAC, after a benign biopsy, and those who had been placed on early recall, with those who received a clear result after mammography (reference group). RESULTS: The response rate was 76 per cent (215/284). All groups of women who went on for further investigation suffered significantly greater adverse psychological consequences (PCs) at five months than women who were given a clear result after mammography. Compared with 10 per cent (5/52) of women who received a clear result after a basic mammogram, adverse psychological consequences were experienced by 59 per cent (27/46, p<0.00001) of the women who were placed on six month early recall, 61 per cent (14/23, p<0.0001) of women who had benign surgical biopsy, 44 per cent (18/41, p<0.0001) of women who received a clear result after assessment (with FNAC), and 45 per cent (23/51, p<0.0001) of women who received a clear result after assessment (without FNAC). Whereas all groups who had gone on for further investigations had experienced a significant decrease in PCs between one month and five months, those who were placed on six month early recall showed no significant difference in PCs between these two time periods. Other factors relating to adverse experiences as a result of breast screening are reported. CONCLUSION: Despite receiving a clear final result, women who undergo further investigation suffer significantly greater adverse psychological consequences five months after their last screening appointment than women who receive a clear result after mammography.     

Results of bilateral cataract extraction with posterior chamber intraocular lens implantation in children

OBJECTIVE: A retrospective study was undertaken to evaluate long-term anatomic and visual outcomes in eyes of children who underwent bilateral intraocular lens implantation. DESIGN: The study design was a review of medical records of 24 children operated on for bilateral cataracts and posterior chamber-intraocular lenses. PARTICIPANTS: Twenty-four children operated on for bilateral cataracts by 1 surgeon between February 1980 and February 1995 were studied. INTERVENTION: Cataract extraction with bilateral posterior chamber-intraocular lens implantation was performed. MAIN OUTCOME MEASURES: Best-corrected visual acuity, visual acuity without correction, intraocular pressure, manifest refraction, and any intraoperative or postoperative complications were measured. RESULTS: At last follow-up (mean follow-up, 50.8 months; range, 10-149 months), the intraocular lens was in good position and the intraocular pressure was normal without medication in all eyes. Four years after surgery, 79.2% (19 of 24) of first eyes achieved a best-corrected visual acuity of 20/40 or better compared to 66.7% (16 of 24) of second eyes. No eye had any loss in best-corrected visual acuity. In first eyes of 3- to 8-year olds at the time of surgery, 73.3% (11 of 15) achieved a spherical equivalent within 2 diopters of the intended at 4 years after surgery compared to 80% of second eyes. In the 9- to 18-year-old group, 88.9% (8 of 9) of first eyes and 100% of second eyes achieved a spherical equivalent within 2 diopters of the intended at 4 years after surgery. Intraoperative and postoperative complications were minimal. CONCLUSIONS: Long-term anatomic and visual results have been gratifying in this series of patients with bilateral implants.     

Poverty, cultural disadvantage and brain development: a study of pre-school children in Mexico

Forty-two children, who had been studied previously at the age of 18-30 months, were studied again at 4 years of age. Twenty-two belonged to low socioeconomic strata and were classified as high-risk children (HRC) the other 20 were classified as low-risk children (LRC), and belonged to middle and middle-high socioeconomic strata. Ten minutes of EEG using reference derivations (with linked earlobes) were recorded from each subject. Twenty EEG segments of 3.2 s each were selected by visual inspection for Fourier analysis. Absolute power (AP) was computed for the total EEG energy (1.5-19 Hz) as well as each reference derivation in 4 frequency bands: delta (1.5-3.5 Hz), theta (4-7.5 Hz), alpha (7.5-12.5 Hz) and beta (12.5-19 Hz). HRC had significantly more delta AP than LRC in frontal and central leads, and higher values of theta AP in frontal leads. Alpha AP was higher in LRC in occipital areas and in F8 and T4. This study suggests a maturational lag in HRC.     

Occlusion therapy of Japanese children with anisometropic amblyopia without strabismus

We examined 38 children (20 boys and 18 girls) with anisometropic amblyopia without strabismus who had been treated with occlusion therapy. At the initial visit, their ages ranged from five to ten years. Their visual acuity scores improved after therapy, and this was unrelated to patient age. The amount of anisometropia, visual acuity at the initial visit, and compliance were related to improved visual acuity in the amblyopic eye. The visual acuity improved for six months after therapy. No further gains were detected thereafter.     

Secretory production of erythropoietin and the extracellular domain of the erythropoietin receptor by Bacillus brevis: affinity purification and characterization

OBJECTIVE: To study the safety and efficacy of methylphenidate in children with the dual diagnosis of epilepsy and attention deficit hyperactivity disorder (ADHD). STUDY DESIGN: Thirty children, aged 6.4 to 16.4 years, with epilepsy and ADHD were studied during a 4-month period. During the initial 2 months of the study, the children were treated with antiepileptic drugs (AEDs) only, and for the remaining 2 months, methylphenidate was added at a morning dose of 0.3 mg/kg. They underwent neurologic assessment, brain computed tomography, IQ testing, and assessment with the Childhood Behavior Checklist at baseline before methylphenidate therapy. Electroencephalography, AED determinations, and the continuous-performance task (CPT) test were done at baseline and after 2 months of methylphenidate therapy. A double-blind, crossover design was used to compare the effects of methylphenidate versus placebo on an electroencephalogram, AED levels, and the CPT. On the 2 days of testing, the child received AEDs and a capsule containing either placebo or methylphenidate. RESULTS: None of the 25 children of this sample who were seizure free had attacks while taking methylphenidate. Of the 5 children with seizures, 3 had an increase in attacks, whereas the other 2 showed no change or a reduction. There were no significant changes in AED levels or electroencephalographic findings. Methylphenidate benefited 70% of children according to parental report; methylphenidate also enhanced performance on the CPT. Side effects of methylphenidate were mild and transient. CONCLUSION: Methylphenidate is effective in treating children with epilepsy and ADHD and safe in children who are seizure free. Caution is warranted for those still having seizures while receiving AED therapy.     

An early marker for neurological deficits after perinatal brain lesions

BACKGROUND: In normal awake infants, fidgety movements are seen from the age of 6 weeks to 20 weeks. The aim of the study was to test the predictive value of absent or abnormal spontaneous movements in young infants for the later development of neurological deficits. METHODS: In a collaborative study involving five hospitals we collected data on the normal and abnormal quality of fidgety movements of 130 infants and compared it with assessments of neurological development done longitudinally until the age of 2 years. On the basis of ultrasound scans infants were classified as at low-risk or at high-risk of neurological deficits. Infants were videoed for 1 h every week from birth to discharge and then for 15 min every 3 to 4 weeks; quality of general movements was assessed. Repeated neurological assessments were also done until 24 months of corrected age. FINDINGS: 67 (96%) of 70 infants with normal fidgety movements had a normal neurological outcome. Abnormal quality or total absence of fidgety movements was followed by neurological abnormalities in 57 (95%) of the 60 infants (49 had cerebral palsy and eight had developmental retardation or minor neurological signs). Specificity and sensitivity of fidgety movement assessment were higher (96% and 95%, respectively) than of ultrasound imaging of the infants' brain (83% and 80%, respectively). INTERPRETATION: Our technique of assessing spontaneous motor activity can identify and distinguish between those infants who require early intervention for neurological abnormalities and those who do not. Our technique is simple, non-intrusive, reliable, quick, and can be done on very young infants.     

Pilot neuropsychological findings from a treatment regimen consisting of intensive chemotherapy and bone marrow rescue for young children with newly diagnosed malignant brain tumors

Ten children (6 girls and 4 boys) who completed a protocol in which their localized brain tumors were successfully treated without cranial irradiation were referred for neuropsychological assessment. At the time of testing, they were disease free without any neuroaxis dissemination or leptomeningeal disease. Tumor types included pineoblastoma, glioblastoma, ependymoma, PNET and medulloblastoma. They had a mean age of 5 years and 8 months (SD = 1.86; range = 2.1-8.9 years) and were an average of 37.8 months post bone marrow transplant (SD = 16.42; range = 14-58 months). Neuropsychological data from this study reveal that the mean scores for this nonradiated group of children were within the average range for the following domains: academic achievement tests of reading, spelling and mathematics, verbal and visual memory, visual-motor integration, social-emotional and behavioral functioning. Furthermore, this group of children were performing within the low average range of overall Intelligence, as well as both verbal IQ/verbal reasoning and performance IQ/abstract visual reasoning. On tasks of fine motor dexterity, this group was within the low average range when using their dominant hand; however, they performed within the borderline range when using their non-dominant hand. Of note, this group of children demonstrated significant deficits within the borderline to impaired ranges on language tasks of expressive picture naming and receptive picture vocabulary.     

Peripheral blood stem cell autografts for the treatment of children over 1 year old with stage IV neuroblastoma: a long-term follow-up

This is the first report of the long-term therapeutic results in 22 children more than 1 year old with stage IV neuroblastoma who were treated with autologous peripheral blood stem cell transplantation (PBSCT). The median age of the patients at PBSCT was 4 years (1 to 10 years) and seven of the 17 patients who were evaluated for N-myc amplification were positive. PBSC were collected by a median of four aphereses per patient. The patients underwent PBSCT from 6 to 21 months after the start of therapy (median 10.5 months) at which time 13 patients were in CR, seven were in PR, and two had refractory disease. Multi-drug therapy using the 'high-MEC' regimen consisting of carboplatinum (400 mg/m2) and VP-16 (200 mg/m2) on days -7 to -4, and melphalan (90 mg/m2) on days -3 and -2, was the primary cytoreductive regimen. The median number of infused MNC and CFU-GM was, respectively, 4.3 x 10(8)/kg and 2.4 x 10(5)/kg. After PBSCT, three patients died of regimen-related toxicities and one patient who was transplanted with refractory disease died of disease progression without any benefit from transplantation. Hematological recovery was evaluated in 21 patients, excluding one early death. The median number of days required to achieve an AGC of >0.5 x 10(9)/l and platelet count of >50 x 10(9)/l were, respectively, 11 and 46. Eleven patients relapsed 3 to 50 months after PBSCT, and currently seven patients (5/13 who were transplanted in CR and 2/7 in PR) are surviving disease-free at 52 to 84 months. Although the retrospective nature of this study and several variables prevent a meaningful analysis, the overall results still support the feasibility of developing a prospective study of PBSCT with a larger number of children with high-risk neuroblastoma.     

Acute generalized exanthematous pustulosis, induced by nystatin

BACKGROUND: Although ERCP is commonly performed in children, the effect of findings at ERCP on the subsequent management of pediatric pancreatitis is unknown. METHODS: We retrospectively reviewed charts to determine the impact of ERCP on the management of recurrent acute or chronic pancreatitis in 17 consecutive children (3 boys and 14 girls, 3 to 16 years, mean 11.2 years) with recurrent acute (n = 13) or chronic pancreatitis (n = 4) who underwent ERCP. Radiographs were reviewed in a blinded manner, and the effect of ERCP findings on subsequent management was determined. RESULTS: In 16 of 17 patients (94%), the pancreatic duct was successfully visualized. Of the 16 studies, 9 (56%) had abnormal findings. A change in therapy occurred in all 9 patients as a result of the findings at ERCP. Of the 7 patients with a prior abnormal CT or ultrasound, 5 (71%) had an abnormal ERCP, all resulting in a change in therapy. Three of the 9 patients (33%) without radiographic abnormalities had an abnormal ERCP that, in each case, resulted in a change in therapy. Overall, findings at ERCP altered therapy in 52% of pediatric patients studied with recurrent acute or chronic pancreatitis. A prior abnormal CT had a high predictive value with respect to ERCP resulting in a change in management (83%). CONCLUSIONS: ERCP is useful in the management of pediatric recurrent acute or chronic pancreatitis; abnormalities are found at a rate similar to those found in adults.     

Binding of properdin to solid-phase immune complexes: critical role of the classical activation pathway of complement

OBJECTIVE: Our objectives were to assess the clinical and microbiological aspects of septic osteoarthritis in children admitted to our center from 1987 until July 1997 and to determine the sensitivity of ultrasound in this age group. PATIENTS AND METHODS: The medical records of 36 children diagnosed as having septic osteoarthritis of the hip were reviewed retrospectively. The diagnosis had been based on clinical criteria, along with synovectomy and drainage of purulent material from the affected joint. An X-ray and/or ultrasound had been performed when the diagnosis was suspected. RESULTS: Nineteen children were diagnosed during the neonatal period, 8 between the ages of 1 and 12 months and 9 older than one year of age. Mean age at diagnosis was 16.8 +/- 6.2 months (median 29 days, range 6 days to 13 years). The hip was involved in 32 children, the ankle in 3 and the elbow in 1. A microbiological diagnosis was achieved in 22 cases (61%) by culture from blood, CSF, and/or synovial fluid. The most common isolates were Gram positive cocci (S. aureus in 9 cases and coagulase negative Staphylococcus in 3). The diagnostic value of the X-rays was very low (18%). The ultrasound was initially considered abnormal in 64.5% of the patients, with a lower sensitivity in the neonatal period. After a mean follow-up period of 36 months, the outcome was good in 86% of the cases, although three children continue with sequelae. Two preterm infants died due to sepsis associated with the osteoarthritis. CONCLUSIONS: At the time of diagnosis of septic arthritis of the hip, the ultrasound is frequently normal. Due to the poor outcome when there is a delay in surgery, we suggest immediate synovectomy and drainage when there is clinical suspicion of septic arthritis despite an apparently normal ultrasound.
