ABSTRACT
Background: Lhermitte-Duclos disease (LDD) is a rare tumor, with only about 300 reported cases. It often shows comorbidity with Cowden syndrome (CS); however, it can occur by itself. Radiologically, the "tiger-stripe" appearance is considered pathognomonic. Surgical resection remains the mainstay of treatment. This report aims to describe the clinical and radiological characteristics of LDD and its relationship with CS according to age group. Methods: PubMed electronic databases were searched in August 2022. The search terms included "Lhermitte- Duclos disease" and "dysplastic gangliocytoma," which yielded 297 and 103 research articles, respectively. The articles were collected and reviewed by three researchers. Results: Out of 400 identified articles, we analyzed 302 reported cases. The mean age at presentation was 33.6 ± 16 years; 171 patients (56.6%) were female, and 123 (40.7%) were male. The most commonly reported symptom was headache (174 patients, 57.6%), followed by ataxia (109, 36.1%). In addition, 99 cases (32.8%) were associated with CS, and 60 (19.9%) had a confirmed phosphatase and tensin homolog (PTEN) mutation. A tiger-stripe appearance was observed in 208 cases (58.7%); surgical resection was performed in 64.2% of the cases. Mortality and recurrence rates were 4.3% and 8.6%, respectively. No statistically significant difference was found between adult- and pediatric-onset LDD for the association with CS (P = 0.128). Conclusion: Our findings suggest that adult and pediatric LDD have major commonalities; however, further prospective studies are warranted.
ABSTRACT
The human monkeypox disease is caused by the monkeypox virus (MPXV), which is a zoonotic disease. In the year 2022, the prevalence of monkeypox cases swiftly increased worldwide and the disease has now been declared a global public health emergency. The present study aimed to assess the public's perceptions and knowledge of and attitudes toward monkeypox in Riyadh, Saudi Arabia. This questionnaire-based cross-sectional study was conducted from 15 May to 15 July 2022. The participants' perceptions, knowledge, and attitudes were collected via a 28-item-based questionnaire survey. The survey was based on 1020 participants (554 (54.3%) were females, and 466 (45.7%) were males). The results reveal that out of 1020 participants, 799 (78.3%) respondents believed that monkeypox disease has developed into a pandemic situation, and 798 (78.2%) suggested that the disease is most common in Western and Central Africa. Further analysis shows that 692 (67.8%) respondents agreed that monkeypox cases are increasing worldwide, 798 (21.8%) believed that monkeypox is commonly transmitted through direct contact, and 545 (53.4%) of respondents reported that it is easily transmitted from human to human. Moreover, 693 (67.9%) participants mentioned that monkeypox disease is spreading more widely as people travel from one country to another, while 807 (79.1%) participants were aware that smallpox and monkeypox have similar clinical features. Furthermore, the majority of participants (p = 0.033) agreed that health officials should start a vaccination campaign to combat monkeypox. Regarding preventive measures and vaccination campaigns, 641 (62.8%) participants suggested that health officials should take public preventive measures and 446 (43.7%) recommended that health officials start vaccination campaigns against monkeypox. The knowledge of human monkeypox among the general population in Riyadh, Saudi Arabia was satisfactory for all ages, genders, levels of education, and economic groups. Moreover, the majority of participants proposed adopting preventive measures and starting a vaccination campaign to combat monkeypox disease. The knowledge of monkeypox in the public domain is a key factor to improve the public's capacity to minimize the disease burden and fight against viral infectious diseases at regional and global levels.
