Case Reports
Ostraceous and inverse psoriasis with psoriatic arthritis as the presenting features of advanced HIV infection.
Knowledge of both the common and atypical presentations of human immunodeficiency virus (HIV)-associated dermatoses may be helpful in arousing suspicion of HIV, especially in patients with no reported risk factors. Herein, we report the case of an otherwise healthy, nonpromiscuous 29-year-old man who presented to our institution with an eight-week history of plaques with oyster shell-like scales on the trunk, extremities and genital area. The plaques were associated with fever, and intermittent knee pain and swelling. ⋯ Repeat skin punch biopsy and arthrocentesis revealed a diagnosis of psoriasis vulgaris with psoriatic arthritis. Due to the atypical presentation of psoriasis, the patient was counselled to undergo HIV testing, which came back positive. Clinicians should be attuned to the skin signs heralding HIV/acquired immunodeficiency syndrome, in order to facilitate early diagnosis and treatment.

Randomized Controlled Trial Comparative Study
Addition of clonidine or lignocaine to ropivacaine for supraclavicular brachial plexus block: a comparative study.
Clonidine is used with local anaesthetics to improve analgesia. However, the improvement conferred when clonidine is used together with ropivacaine is controversial. Thus, the present study aimed to evaluate the improvement in analgesia when clonidine is used together with ropivacaine for supraclavicular brachial plexus block. ⋯ When compared to the use of ropivacaine alone, the addition of 150 μg clonidine to ropivacaine for brachial plexus block achieved earlier analgesic onset and improved duration of analgesia, without unwanted side effects.

Brugada syndrome (BrS) is a common genetic cause of sudden cardiac arrest (SCA) due to polymorphic ventricular tachycardia and ventricular fibrillation. The current recommended therapy for high-risk BrS patients is the use of an implantable cardioverter defibrillator (ICD). The present study aimed to report the clinical characteristics and treatment outcomes of BrS patients in northeastern Thailand. ⋯ Clinical characteristics did not distinguish between symptomatic BrS patients and asymptomatic patients with Brugada ECGs. The clinical characteristics and treatment outcomes for the symptomatic BrS patients with SCA and unexplained syncope were similar. Among the BrS patients implanted with secondary prevention ICD in Northeastern Thailand, nearly one-third had received appropriate ICD therapy, far exceeding the incidence of device-related complications and inappropriate therapy.
