Introduction: Human papillomavirus (HPV) testing is used as a means of triaging cervico-vaginalsmears with low grade squamous abnormalities or as part of co-testing with cytology. While HPVtesting has a high sensitivity, it has a low specificity in detecting cervical intraepithelial neoplasiagrade 2 and above (CIN 2+) leading to unnecessary colposcopy referrals. We investigate the accuracyof the p16/Ki-67 dual immunocytochemical stain in determining the presence of CIN 2+ lesions onhistology and its potential as a superior biomarker for triage. Methods: Liquid based cervico-vaginalcytology specimens with squamous abnormalities and corresponding histology from 97 women withsubsequent colposcopy and biopsy were included. The specimens were then subjected to the dual stainand Roche Cobas 4800 multiplex real time PCR HPV DNA testing. The sensitivity and specificity ofthe dual stain and HPV testing were calculated using CIN 2+ on histology as a reference standard.Results: The sensitivity and specificity of the dual stain in detecting histology proven CIN 2+ was93.7% and 76.5% while HPV testing was 85.7% and 14.7% respectively. Of the 44 women withASCUS or LSIL on cytology, the dual stain also reduced the number of unnecessary colposcopyreferrals from 27 to 7 when used as a triage marker compared to HPV testing. Conclusion: p16/Ki-67dual stain was more sensitive and specific than HPV testing in determining the presence of CIN 2+on histology. It could triage low grade cervico-vaginal specimens more effectively and potentiallyhelp women avoid unnecessary colposcopies. Future studies are needed to further evaluate its rolein cervical cancer screening programmes.

INTRODUCTIONAtopic dermatitis is a common, chronic pruritic condition affecting both children and adults, which has a negative impact on the quality of life. These guidelines were developed by an expert workgroup appointed by the Dermatological Society of Singapore, to provide doctors with information to assist in the management of their patients with atopic dermatitis. The workgroup members are experienced dermatologists with interest and expertise in eczemas.

MATERIALS AND METHODSWorkgroup members arrived at a consensus on the topics to be included. Relevant studies from the literature were assessed for best evidence, supplemented by the collective experience of the workgroup.

RESULTSFor mild atopic dermatitis, emollients, mild potency topical steroids and topical calcineurin inhibitors are recommended. For moderate-to-severe atopic dermatitis, the use of emollients, moderate-to-potent topical steroids, topical calcineurin inhibitors, wet dressings, antimicrobials for secondary skin infection, phototherapy, and systemic therapy (e.g. prednisolone, cyclosporine, azathioprine or methotrexate) may be warranted. Patients with moderate-to-severe atopic dermatitis should be managed in conjunction with a dermatologist.

CONCLUSIONGood outcomes can be achieved with an individualised therapeutic approach combined with adequate patient and parental education.

Cutaneous pseudolymphoma is an uncommon, benign lymphoproliferative disorder of the skin. Although this condition is most commonly idiopathic, its occurrence has been associated with cosmetic tattoos. We report a unique case of cutaneous pseudolymphoma that occured after accidental, traumatic inoculation of a red pigment in a healthy 33-year-old woman.
