Oesophageal atresia: The growth gap

Poor growth is an under-recognised yet significant long-term sequelae of oesophageal atresia(OA) repair. Few studies have specifically explored the reasons for growth impairment in this complex cohort. The association between poor growth with younger age and fundoplication appears to have the strongest supportive evidence, highlighting the need for early involvement of a dietitian and speech pathologist, and consideration of optimal medical reflux management prior to referring for anti-reflux surgery. However, it remains difficult to reach conclusions regarding other factors which may negatively influence growth, due to conflicting findings, inconsistent definitions and lack of validated tool utilisation. While swallowing and feeding difficulties are particularly frequent in younger children, their relationship with growth remains unclear. It is possible that these morbidities impact on the diet of children with OA, but detailed analysis of dietary composition and quality, and its relationship with these complications and growth, has not yet been conducted. Another potential area of research in OA is the role of the microbiota in growth and nutrition. While the microbiota has been linked to growth impairment in other paediatric conditions,it is yet to be investigated in OA. Further research is needed to identify the most,important contributory factors to poor growth, the role of the intestinal microbiota, and effective interventions to maximise growth and nutritional outcomes in this cohort.     

Imaging-based algorithmic approach to gallbladder wall thickening

Gallbladder(GB) wall thickening is a frequent finding caused by a spectrum of conditions. It is observed in many extracholecystic as well as intrinsic GB conditions. GB wall thickening can either be diffuse or focal. Diffuse wall thickening is a secondary occurrence in both extrinsic and intrinsic pathologies of GB, whereas, focal wall thickening is mostly associated with intrinsic GB pathologies. In the absence of specific clinical features, accurate etiological diagnosis can be challenging. The survival rate in GB carcinoma(GBC) can be improved if it is diagnosed at an early stage, especially when the tumor is confined to the wall. The pattern of wall thickening in GBC is often confused with benign diseases, especially chronic cholecystitis, xanthogranulomatous cholecystitis, and adenomyomatosis. Early recognition and differentiation of these conditions can improve the prognosis. In this minireview, the authors describe the patterns of abnormalities on various imaging modalities(conventional as well as advanced) for the diagnosis of GB wall thickening. This paper also illustrates an algorithmic approach for the etiological diagnosis of GB wall thickening and suggests a formatted reporting for GB wall abnormalities.     

Primary scrotal tuberculosis: A rare but intriguing entity

Introduction

Tuberculosis (TB) of the genitourinary tract is usually secondary to a primary site in another part of the body. Primary scrotal TB is an extremely rare condition and it may mimic viral orchitis, epididymitis, hydrocele, spermatocele, testicular torsion, scrotal trauma, or a tumour.

Case presentation

A 45-year-old man presented with a 3-month history of diffuse scrotal enlargement followed a month later by swelling in the left groin. Scrotal ultrasonography revealed a 4 cm x 4 cm hypoechoic, heterogeneous, inflammatory mass with multiple fistulae at the bottom of the scrotum without any extension to the deeper structures, and bilateral multiple inguinal adenopathy.

Discussion

Genitourinary TB may present with adrenal insufficiency, renal disease, obstructive uropathy and chronic cystitis with sterile pyuria. Although scrotal USG is very helpful, it is not a definitive diagnostic tool. Histopathology is mandatory either in the form of FNAB or formal biopsy. Most cases respond well to antitubercular drugs only.

Conclusion

An optimum diagnostic and therapeutic protocol is urgently needed for cases of primary scrotal TB to prevent misuse of costly investigations and treatments and to avoid unnecessary surgical interventions when the patient can be cured by antitubercular treatment only.
