The objective of this review was to describe the variations in the density and distribution of CLCs associated with ureteropelvic junction obstruction (UPJO). Materials and Methods: Studies comparing the density and distribution of CLCs in the human upper urinary tract in patients with UPJO and healthy controls were included in this systematic review. We searched online electronic databases; Ovid MEDLINE, Scopus, PubMed and Cochrane reviews for the studies published before October 31, 2020. A meta-analysis was conducted to compare the density of CLCs at the ureteropelvic junction (UPJ) in patients with UPJO and matched controls. Results: We included 20 and seven studies in the qualitative and quantitative synthesis, respectively. In majority (55%) CLCs were located between t...

We report two children with parotid abscess, which is one of the common clinical manifestations in the paediatric population in Southeast Asia but rare in Northern Australia. Both were previously healthy. The children recovered completely after surgical drainage and antibiotic treatment according to standard guidelines. Because the spectrum of disease in childhood is different from that in adults and underlying predisposing factors are usually not seen in children, a high index of suspicion is required for the diagnosis of paediatric melioidosis. Raising awareness among paediatricians in Sri Lanka of the clinical presentations of melioidosis in childhood is a prerequisite for improved ascertainment. The key role of the microbiology laboratory in the diagnosis of melioidosis is highlighted.

Methods: Clinical records of consecutively admitted 103 children were analysed. Results: 85 children were successfully treated with a single attempt of saline reduction while another 11 patients were successfully managed with second or third attempt of saline reduction. Only seven children needed laparoto my. Overall success rate of the procedure in this sample was 93.2%. Conclusions: Hydrostatic reduction can be used effectively and safely in the absence of ultrasound facilities to manage uncomplicated intussusceptions.

Ÿ Diagnosis of hamatoma is difficult due to lack of experience and resource materials. Ÿ Focus radiological assessment by an experience radiologist is pivotal and multidisciplinary surgical approach is essential.

On examination, a firm inguinal lymph node mass was palpable. The rest of the clinical examination was normal.

Infrequent vomiting gradually became forceful and after each breastfeed. He was active and sucking well. He was born at term after an uneventful pregnancy weighing 2.98kg.
