Abstract: Positional plagiocephaly is the most common type of cranial asymmetry affecting infants. We aimed to investigate the effectiveness of helmet therapy compared to no helmet therapy in treating positional plagiocephaly in infants under the age of 1year. This retrospective review was conducted in an Australian paediatric hospital and included 171 patients recruited from outpatient clinics. Only 30 patients had positional plagiocephaly scores recorded at first and final consultations while 39 patients had diagonal measurements recorded at both visits. The mean age was 7.38months at initial consultation with a mean follow-up duration of 5.85months. Those who had helmet therapy had a significantly greater reduction in diagonal difference than those who did not use helmets (p=0.011). Therefore, there may be a role for helmet therapy in the treatment of severe positional plagiocephaly.

Abstract: In primary parotid gland malignancies, the incidence of level‐specific cervical lymph node metastasis in clinically node‐positive necks remains unclear. This study aimed to determine the incidence of level‐specific cervical node metastasis in clinically node‐negative (cN0) and node‐positive (cN+) patients who presented with primary parotid malignancies. Electronic databases (MEDLINE, EMBASE, PubMed, Cochrane). Random‐effects meta‐analysis was used to calculate pooled estimate incidence of level‐specific nodal metastasis for parotid malignancies with 95% confidence intervals (CIs). Subgroup analyses of cN0 and cN+ were performed. Thirteen publications consisting of 818 patients were included. The overall incidence of cervical nodal involvement in all neck dissections was 47% (95% CI, 31%‐63%). Among those who were cN+, the incidence of nodal positivity was 89% (95% CI, 75%‐98%). Those who were cN0 had an incidence of 32% (95% CI, 14%‐53%). In cN+ patients, the incidence of nodal metastasis was high at all levels (level I 33%, level II 73%, level III 48%, level IV 39%, and level V 37%). In cN0 patients, the incidence of nodal metastasis was highest at levels II (28%) and III (11%). For primary parotid malignancies, the incidence of occult metastases was 32% compared to 89% in a clinically positive neck. It is recommended that in iduals with a primary parotid malignancy requiring elective treatment of the neck have a selective neck dissection which involves levels II to III, with the inclusion of level IV based on clinical judgment. Those undergoing a therapeutic neck dissection should undergo a comprehensive neck dissection (levels I‐V).

Abstract: Coins are the commonest foreign body ingested in paediatric populations. Although most ingested coins are either spontaneously passed or retrieved with medical intervention without serious consequence, there is potential for serious morbidity and mortality related to paediatric coin ingestion. We performed a 10-year retrospective review of Australian denomination coin ingestion at a tertiary paediatric hospital in Sydney, Australia. We attempted to determine whether a relationship exists between coin size, patient age, coin ingestion and spontaneous passage. Hospital records of all children presenting in a 10-year period to a paediatric tertiary care centre for coin ingestion were reviewed. Demographic information, coin denomination, previous history, symptoms, investigations, management, outcome and complications were recorded. 241 cases were identified. The majority (55%) of cases occurred in children ≤3 years of age (range 7 months-11 years, mean 3.39 years). The most common location where coins were identified was in the proximal third of the oesophagus or at the cricopharyngeus (65%). Spontaneous passage occurred in 84 cases (34.9%) while 167 cases (69.3%) required intervention. Children ≤3 years were more likely to ingest small coins ( 3 years were more likely to ingest larger coins (22-26 mm) (OR: 2.17 1.39-4.35). Coin size, coin weight and age of the child appear to be predictors for both likelihood of ingestion and spontaneous passage in paediatric coin ingestion cases. A child with minimal symptoms, witnessed ingestion and radiographic identification of the coin in the lower oesophagus or more distal can often be safety observed for up to 24 h in anticipation of spontaneous passage.
