A 10-years retrospective study on Severe Cutaneous Adverse Reactions (SCARs) in a tertiary hospital in Penang, Malaysia

Introduction: Severe cutaneous adverse drug reactions(SCARs) are not uncommon and potentially lifethreatening.Our objective is to study the patientcharacteristics, the pattern of implicated drugs andtreatment outcome among patients with SCARs.Methods: A 10-year retrospective analysis of SCARscases in Penang General Hospital was carried out fromJanuary 2006 to December 2015. Data collection is basedon the Malaysian Adverse Drug Reactions AdvisoryCommittee registry and dermatology clinic records.Results: A total of 189 cases of SCARs were encountered(F:M ratio; 1.2:1.0; mean age of 45 year). The commonestmanifestation was Stevens-Johnson Syndrome [SJS](55.0%), followed by toxic epidermal necrolysis [TEN](23.8%), drug rash with eosinophilia and systemicsymptoms [DRESS] (12.7%), acute generalisedexanthematous pustulosis [AGEP] (4.8%), SJS/TENoverlap syndrome (2.6%) and generalised bullous fixeddrug eruptions [GBFDE] (1.1%). Mean time to onset forTEN/SJS/Overlap syndrome was 10.5±13 days; AGEP,three days; GBFDE, 2.5±0.7 days, and DRESS, 29.4±5.7days. The most common drugs implicated wereantibiotics (33.3%), followed by allopurinol (18.9%) andanticonvulsant (18.4%). Out of 154 cases ofSJS/TEN/overlap syndrome, allopurinol was thecommonest causative agents (20.1%). In DRESS,allopurinol accounts for 45.8% of the cases. The mortalityrate in SJS, TEN and DRESS were 1.9%, 13.3% and 12.5%respectively. No mortality was observed in AGEP andGBFDE.Conclusion: The commonest manifestations of SCARs inour setting were SJS, TEN and DRESS. Allopurinol wasthe most common culprit. Thus, judicious allopurinol useis advocated and pre-emptive genetic screening for HLAB*5801 should be consider

Atypical Presentation of Cutaneous Larva Migrans: A Case Report & Literature Review

Cutaneous larva migrans, also known as “migrant linear epidermitis”, “beach worm”, “migranthelminthiasis”, “dermatitis serpiginosus” or “creeping eruption”. It is a zoonosis which caused byaccidental percutaneous inoculation of helminth larvae, usually parasites of the small intestines of catsand dogs. It typically presents as an itchy, erythematous, serpiginous, cutaneous eruption. We describea case of disseminated and extensive infection of cutaneous larva migrans in a 21-year-old traveler,leading a delay in diagnosis and treatment.
