INTRODUCTION

Childhood Polyarteritis Nodosa (PAN) is a rare, systemic necrotizing vasculitis of the small to medium-sized vessels with an uncertain global distribution. The primary etiology is unknown. However, PAN is commonly associated with preceding Group A streptococcus infection in children. The most common cutaneous manifestations of PAN include tender subcutaneous nodules, livedo reticularis, digital ischemia and ulceration. To date, no reports have documented cutaneous PAN as a sequela of rheumatic fever.

CASE REPORT

This is a report of a 7-year-old Filipino male who presented with multiple, well-defined erythematous to hyperpigmented, firm, tender nodules, with some areas of lace or net-like macules and patches, some resolved leaving hyperpigmentation measuring 1x1 cm to 2x2 cm on the lower back, bilateral upper and lower extremities accompanied by fever, malaise, arthralgia and myalgia with a previous history of rheumatic fever. A 6mm skin punch biopsy revealed findings consistent with PAN. The patient was managed with prednisone. Due to the limited response to treatment, he was eventually given mycophenolate mofetil.

CONCLUSION

Childhood polyarteritis nodosa (PAN) is a rare form of necrotizing inflammation of the medium-sized blood vessels primarily linked to Group A streptococcal infection in children, with no known reported cases associated with rheumatic fever. However, in this case, we were able to observe that PAN could present as a probable rare sequela of rheumatic fever. This warrants close follow-up among such patients.

BACKGROUND: Chronic illnesses such as Type 2 diabetes mellitus (T2DM) and obesity have been implicated as risk factors in the development of cognitive impairment (CI), but despite this, definite association between the two conditions in increasing cognitive impairment risk is not well defined. OBJECTIVE: This study aims to examine the association between body mass index (BMI) and cognitive impairment (CI) in elderly patients with Type 2 diabetes mellitus. METHODS: This is a cross-sectional study conducted in the outpatient clinics of a private hospital in Manila which included elderly patients with Type 2 diabetes. BMI categories of the subjects were determined using the Asia-Pacific criteria and the Montreal Cognitive Assessment – Philippines (MOCA-P) was administered to subjects who fulfilled the inclusion criteria. Descriptive statistics were used to determine the prevalence of impaired cognition among subjects while risk ratio analysis was used to determine the correlation between BMI and CI. Correlation analysis and linear regression analysis were used to determine the presence of association between cognition (measured by MOCA-P scores) and BMI. For all analysis, a 95% level of significance was used. RESULTS: A total of 109 subjects from the outpatient clinics were included in the study. A high percentage of the study population (90.83%) had CI based on MOCA-P scores. Subjects that belonged to the extremes of BMI- underweight and obese class 2 had higher incidence of CI compared to the other groups. Underweight subjects had 1.103 (95% CI: 1.038 to 1.172) times likelihood of having impaired cognition (p-value 0.0016), while obese 2 subjects had 1.110 (95% CI: 1.040 to 1.184) times likelihood of having impaired cognition (p-value 0.0016). Regression analysis revealed that in subjects with diabetes of less than 10 years, cognition scores were negatively correlated to BMI (p-value 0.0454). Correlation analysis revealed that at the general population level, regardless of the external factors, increasing or decreasing BMI did not have significant effect on cognition scores. CONCLUSION Subjects who belonged to the extremes of BMI-underweight and obese class 2 – had higher incidence of CI compared to the other BMI groups. Among subjects with T2DM duration of less than 10 years, cognition scores tend to be negatively correlated to BMI.

INTRODUCTION: Misuse of prescription medicines and the harms associated with such use are growing threats across the world. There is currently, however, limited data on the extent of prescription medicine misuse in Singapore and whether this is a current threat in the country. METHODS: An online survey, limited to 1,000 individuals (aged 21 years and over) who were residents in Singapore, was administered through a survey panel company in September 2015. The survey collected information on participant demographics, and their awareness, self-reported lifetime and past-year misuse of commonly available prescription medicines in Singapore as well as the use of a range of recreational drugs and novel psychoactive substances (NPS). RESULTS: Lifetime (6.7%) and past-year (4.8%) misuse of any prescription medicine was comparable to lifetime (6.0%) and past-year (3.0%) use of any recreational drugs/NPS. The top five prescription medicines for lifetime misuse were: diazepam (2.7%); codeine (2.3%); dhasedyl (promethazine, codeine and ephedrine; 1.6%); panadeine (paracetamol and codeine; 1.5%); and methylphenidate (1.2%). The top five drugs for past-year misuse were: diazepam (1.6%); codeine (0.9%); panadeine (0.7%); alprazolam (0.6%); baclofen (0.6%); and gabapentin (0.6%). CONCLUSION Misuse of prescription medicine in Singapore was common, with prevalence comparable to the use of recreational drugs/NPS. A common source for misused drugs was physicians. Further studies are required to determine whether this is more widespread in Singapore and establish the different forms of drug diversion, so that appropriate prevention strategies can be implemented.

Systemic infections due to Fusobacterium may originate in the tonsillar/internal jugular veins or from the abdomen. We encountered a patient who presented with bacteremia, fulminant septic shock, and extensive soft tissue pyogenic infection due to Fusobacterium necrophorum.In addition, there was widespread metastatic colon cancer with the unique finding of premortem co-localization of F. necrophorum and cancer cells at a site distant from the colon. We reviewed the literature of the association of F. necrophorum and colon cancer, and discuss the evidence of how each of these 2 distinct entities may mutually augment the development or progression of the other.
