HIV Dementia: A Bibliometric Analysis and Brief Review of the Top 100 Cited Articles.

Dementia is a syndrome of cognitive impairment that affects an individual's ability to live independently. The number of people living with dementia worldwide in 2015 was estimated at 47.47 million. The American Academy of Neurology (AAN) criteria for human immunodeficiency virus (HIV)-associated dementia (HAD) require an acquired abnormality in at least two cognitive (non-motor) domains and either an abnormality in motor function or specified neuropsychiatric/psychosocial domains. HIV is the most common cause of dementia below 60 years of age. Citation frequencies are commonly used to assess the scholarly impact of any scientific publication in bibliometric analyses. It helps depict areas of higher interest in terms of research frequency and trends of citations in the published literature and identify under-explored domains of any field, providing useful insight and guidance for future research avenues. We used the database "Web of Science" (WOS) to search for the top 100 cited articles on HIV-associated dementia. The keywords "HIV dementia" and "HIV-associated neurocognitive disorders" (HAND) were used. The list was generated by two authors after excluding articles not pertaining to HIV dementia. The articles were then assigned to authors to extract data to make tables and graphical representations. Finally, the manuscript was organized and written describing the findings of the bibliometric study. These 100 most cited articles on HIV dementia were published between years 1986 and 2016. The highest number of the articles was from 1999 (n=9). The year 1993-2007 contributed consistently two publications to the list. The articles are from 42 journals, and among them, the Annals of Neurology (n=16) and the Journal of Neurology (n=15) published most of the articles. Justin C. McArthur with 25 publications contributed the highest number of papers to the list by any author. The USA collaborated in the highest number of publications (n=87). American institutes were leading the list with the most publications. The Johns Hopkins University collaborated on 37 papers. The most widely studied aspect of HIV dementia was pathogenesis. Incidence and prevalence, clinical features, and pre- and post-highly active antiretroviral therapy (HAART) era were also discussed in the articles. Beyond America, the research should be expanded to low-income countries and those affected more by HIV. Therefore, other countries and their institutes should participate more in HIV-associated dementia research. Anticipating the rising resistance to existing antiretrovirals, we should develop new therapeutic options. There is room for research in many aspects of HIV dementia care.

Hereditary Chorea Associated With and Aggravated by Systemic Lupus Erythematosus.

Chorea is caused by a number of conditions, including genetic, metabolic derangements, infections, drugs, toxins, tumors, and disorders of the immune and inflammatory system of the body. Huntington's disease (HD) is the most common genetic cause of chorea. Systemic lupus erythematosus (SLE) is an autoimmune condition. Common symptoms include oral ulcers, joint pain, malar or discoid rashes, photosensitivity, and blood dyscrasias. It can involve the heart, lungs, kidneys, and brain. SLE can cause neuropsychiatric manifestations like psychosis, seizures, headache, confusion, and stroke. Chorea is a known symptom of SLE. HD is now recognized to involve more than one system and is associated with a number of comorbid conditions. We report the first case of hereditary choreiform disorder associated with and aggravated by SLE. This is also the first case report of probable Huntington disease from Balochistan, Pakistan. We report a 19-year-old girl with choreiform disorder and a family history of chorea. Choreiform disorder was present in her paternal grandmother and uncles. She presented with fever, cough, and aggravation of choreiform movements of upper and lower limbs for 10 days. She also complained of pain in the small joints of her hands and feet, oral ulcers, hair loss, and aggravation of choreiform movements for two and half months. Probable differential diagnoses of HD, Wilson's disease, and other types of hereditary chorea, aggravated by infections, SLE, or Covid-19, were made. Her initial lab results revealed pancytopenia, increased D-dimers and serum ferritin, positive antinuclear antibodies (ANA), and anti-double-stranded DNA (anti-dsDNA). Her C3 and C4 complement factors were low. The rest of the lab test results, including polymerase chain reaction (PCR) coronavirus disease (COVID-19), blood culture, and malaria, were negative. Thus, a diagnosis of hereditary chorea associated with and aggravated by SLE was made. Hereditary choreiform disorders can be associated with and aggravated by autoimmune conditions like SLE. Thus, it is recommended to be vigilant and have a low threshold for diagnosing co-existing autoimmune conditions like SLE in patients with hereditary choreiform disorder.

Ascaris Lumbricoides Infestation as an Unexpected Cause of Acute Pancreatitis.

Ascariasis is the most common helminthic infection. It is most common in children of tropical and developing countries where the transmission is by contamination of soil by human feces or use of untreated feces as fertilizer. Transmission in most endemic areas is via person to person contact. We hereby present a case report of acute pancreatitis due to ascariasis. Twenty-five-year-old male patient presented to us with chief complaint of acute epigastric pain radiating to back and associated with vomiting. Initial lab investigations revealed increased serum amylase and lipase. Probable diagnosis of acute pancreatitis was made. CT scan was done and report revealed bulky pancreas, and significant peri-pancreatic fat stranding. He was managed symptomatically with intravenous fluids, analgesics, anti-emetics and enteral nutrition. However, the cause remained undetermined as we ruled out the possible etiologies of acute pancreatitis until one day the patient vomited a 15-cm round worm. Thereafter, his condition improved dramatically. This is one of the first few case reports of ascariasis-induced pancreatitis from Pakistan and the first one from Baluchistan province of Pakistan. Thus it highlights ascariasis as possible etiology of acute pancreatitis in regions where ascariasis is geographically endemic.
