Reversible Cerebral Vasoconstriction Syndrome Mimicking Eclampsia.

This report describes the case of an 18-year-old Micronesian pregnant woman at 32 weeks gestation, initially presumed to have eclampsia but later diagnosed with reversible cerebral vasoconstriction syndrome (RCVS). She presented with seizures, altered mental status, nystagmus, lower extremity weakness, and absent reflexes. An extensive workup ruled out infectious and autoimmune causes, but a computed tomography angiogram (CTA) revealed severe cerebral vasoconstriction. Treatment included levetiracetam, intravenous magnesium, and nimodipine. The case highlights the challenge of differentiating RCVS from eclampsia in the postpartum period, emphasizing the importance of considering alternative diagnoses and brain CTA when RCVS is suspected, with calcium channel blockers potentially contributing to favorable neurological outcomes.

Are Patients with HHV-8 Associated Castleman Disease Successfully Treated with Rituximab at Risk of Subsequently Developing HHV-8 Negative (Idiopathic) Castleman Disease?

Introduction: Multicentric Castleman disease (MCD) is a lymphoproliferative disorder characterized by lymph node histopathology and systemic symptoms. To our knowledge, there are no descriptions in the literature of long-term outcomes of human herpesvirus-8 (HHV-8)-associated MCD. Case Description: We report a case of a 70-year-old male living with human immunodeficiency virus and a history of human herpesvirus-8 (HHV-8)-associated MCD. The patient reported having had low-grade fever for two weeks. Extensive workup revealed systemic lymphadenopathy without evidence of autoimmune disease or malignancy. Lymph node biopsy was consistent with HHV-8-negative idiopathic MCD (iMCD). The patient was subsequently scheduled for anti-interleukin-6 therapy. Discussion: The present case is the first report of probable development of iMCD after long-term follow-up for HHV-8-associated MCD. The case illustrates the possible long-term consequences of MCD, suggesting the necessity of further research on the pathogenesis of CD. Conclusion: Given the uncertainty in the long-term outcomes of HHV-8-associated MCD, periodic surveillance of patients with a history of HHV-8-associated MCD is warranted. Prospective nationwide cohort studies comparing characteristics of HHV-8-associated MCD and iMCD would bring further insights. LEARNING POINTS: This is the first case describing the probable development of HHV-8-negative idiopathic MCD after HHV-8-associated MCD.Little is known of long-term outcomes of HHV-8-associated MCD and idiopathic MCD, necessitating periodic surveillance.HHV-8-negative idiopathic MCD patients are treated with siltuximab, an interleukin-6 inhibitor, unlike patients with HHV-8-associated MCD, who benefit most from rituximab.

Breaking the Barrier: A Study on Multi-drug Resistance in Breast Abscess at an Academic Malaysian Hospital.

BACKGROUND: In recent years, the increase in antibiotics usage locally has led to a worrying emergence of multi-drug resistant organisms (MDRO), with the Malaysian prevalence rate of methicillin-resistant Staphylococcus aureus (MRSA) ranging from 17.2 to 28.1% between 1999 and 2017. A study has shown that 7% of all non-lactational breast abscesses are caused by MRSA. Although aspiration offers less morbidities compared to surgical drainage, about 20% of women infected by MRSA who initially underwent aspiration subsequently require surgical drainage. This study is conducted to determine the link between aetiology, antimicrobial resistance pattern and treatment modalities of breast abscesses. METHODS: Retrospective study of reviewing microbiology specimens of breast abscess patients treated at Universiti Malaya Medical Centre from 2015 to 2020. Data collected from microbiology database and electronic medical records were analysed using SPSS V21. RESULT: A total of 210 specimens from 153 patients were analysed. One-fifth (19.5%) of the specimens isolated were MDRO. Lactational associated infections had the largest proportion of MDR in comparison to non-lactational and secondary infections (38.5%, 21.7%, 25.7%, respectively; p = 0.23). Staphylococcus epidermidis recorded the highest number of MDR (n = 12) followed by S. aureus (n = 8). Adjusted by aetiological groups, the presence of MDRO is linked to failure of single aspirations (p = 0.554) and significantly doubled the risk of undergoing surgical drainage for resolution (p = 0.041). CONCLUSION: MDR in breast abscess should be recognised as an increasing healthcare burden due to a paradigm shift of MDRO and a rise of resistance cases among lactational associated infection that were vulnerable to undergo surgical incision and drainage for resolution.

Realist evaluation of a transdisciplinary mealtime management service for autistic children.

LAY ABSTRACT: Mealtimes and eating can be difficult for autistic children. A service where different professions work together is required to address the varied and complex mealtime difficulties of autistic children. Little is known about what is needed for such services to be effective. We interviewed six caregivers of autistic children who were engaged in a mealtime service and 10 therapists who are involved in delivering the service to understand their perspectives on the factors that were driving the effectiveness of the mealtime service. We found that different health professionals from different disciplines working together, focusing on adapting intervention to the child and family and managing expectations of the caregiver were important in contributing to outcomes of the mealtime service. The findings of this study can be used to inform the development of more effective interventions and services to support the well-being and development of autistic children.

Respiratory microorganisms in acute pharyngitis patients: Identification, antibiotic prescription patterns and appropriateness, and antibiotic resistance in private primary care, central Malaysia.

Acute pharyngitis (AP) is a common reason for private primary care consultations, thus providing an avenue for widespread antibiotic intake among the community. However, there is limited data on the antibiotic prescription appropriateness and resistance information in the Malaysian private primary care setting, therefore, this study aimed to investigate the prevalence of isolated viruses and bacteria, antibiotic resistance patterns, antibiotic prescription patterns and appropriateness by general practitioners (GPs) and factors affecting antibiotic resistance and antibiotic prescription patterns. To investigate, a cross-sectional study was conducted among 205 patients presenting with AP symptoms at private primary care clinics in central Malaysia from 3rd January 2016 to 30th November 2016. Throat swabs were collected from 205 AP patients for two purposes: (i) the detection of four common respiratory viruses associated with AP via reverse-transcription real-time PCR (qRT-PCR); and (ii) bacterial identification using matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOF MS). Bacterial isolates were then subjected to antibiotic susceptibility screening and McIsaac scoring was calculated post-prescription based on GP selection of criteria. Generalized estimating equations analysis with multiple logistic regression was conducted to identify factors associated with presence of virus and antibiotic prescription. The results showed that 95.1% (195/205) of patients had at least one of the four viruses, with rhinovirus (88.5%) being the most prevalent, followed by adenovirus (74.9%), influenza A virus (4.6%) and enterovirus (2.1%). A total of 862 non-repetitive colonies were isolated from the culture of throat swabs from 205 patients who were positive for bacteria. From a total of 22 genera, Streptococcus constitutes the most prevalent bacteria genus (40.9%), followed by Neisseria (20%), Rothia (13.0%), Staphylococcus (11%) and Klebsiella (4.9%). Only 5 patients carried group A beta-hemolytic streptococci (GABHS). We also report the presence of vancomycin-resistant S. aureus or VRSA (n = 9, 10.1%) among which one isolate is a multidrug-resistant methicillin-resistant S. aureus (MDR-MRSA), while 54.1% (n = 111) were found to carry at least one antibiotic-resistant bacteria species. Application of the McIsaac scoring system indicated that 87.8% (n = 180) of patients should not be prescribed antibiotics as the majority of AP patients in this study had viral pharyngitis. The antibiotic prescription appropriateness by applying post-prescription McIsaac scoring was able to rule out GABHS pharyngitis in this sample with a GABHS culture-positive sensitivity of 40% (n = 2/5) and specificity of 90% (180/200). In conclusion, antibiotic-resistant throat isolates and over-prescription of antibiotics were observed and McIsaac scoring system is effective in guiding GPs to determine occurrences of viral pharyngitis to reduce unnecessary antibiotic prescription.

Eosinophilic Myocarditis Presenting as Cardiac Tamponade: A Diagnostic Challenge.

Eosinophilic myocarditis (EM) is a rare cause of acute heart failure. It can occur secondary to drug hypersensitivity, autoimmune diseases such as vasculitis, idiopathic hypereosinophilic syndrome (HES) or malignancy, but is often under-recognized and underdiagnosed, being confused with other causes of heart failure. While EM is associated with various clinical symptoms, it is rarely associated with cardiac tamponade that requires urgent pericardiocentesis. Here we describe a patient with EM who presented with cardiac tamponade and decompensated heart failure likely secondary to autoimmune disease. LEARNING POINTS: Work-up for hypereosinophilia should include the identification of treatable causes as well as end-organ dysfunction requiring urgent treatment.In patients presenting with acute heart failure and cardiac tamponade of unclear aetiology, eosinophilic myocarditis should be considered whether or not hypereosinophilia is present on presentation.When invoking the diagnosis of eosinophilic myocarditis, extensive efforts should be made to identify primary causes, such as autoimmune conditions including vasculitis.

Overlooking Recurrent Acute Rheumatic Fever in Adulthood.

Acute rheumatic fever in an adult is a rare entity. We present a 29-year-old man of mixed ancestry, including Native Hawaiian and other Pacific Islander, who presented with a 6-week history of migratory polyarthralgia and fever with a recent history of purulent lower extremity wounds and a remote history of acute rheumatic fever in childhood. The diagnosis of recurrent acute rheumatic fever was confirmed by elevated Antistreptolysin-O titers and Anti-DNase B titers. This case presentation showcases a Native Hawaiian and other Pacific Islander with acute rheumatic fever in both childhood and adulthood following pyoderma infection, with a delay in diagnosis and management for both episodes. The patient had an excellent response to naproxen without developing complications and was restarted on secondary antibiotic prophylaxis. Health care providers in the Pacific region should understand the relationship between pyoderma and acute rheumatic fever in addition to including acute rheumatic fever in the differential diagnosis of polyarthralgia in an adult.
