Ascaris-induced intestinal obstruction is a rare complication primarily seen in children in areas with a high prevalence of worm infestations. It can occur through 2 mechanisms: immune-mediated reactions releasing neurotoxins that cause contractions and inflammation in the small intestine (aperistalsis), or mechanical obstruction by adult worms, commonly at the ileocecal valve. Partial obstructions are managed conservatively, while complete obstructions often require surgical intervention. In a recent case, a 19-year-old male presented with persistent abdominal pain, vomiting, and inability to pass stools, and gas. Imaging revealed partial obstruction, and conservative management with fluids, a nasogastric tube, and antibiotics led to the spontaneous passage of worms, relieving symptoms. The patient was discharged with anthelmintics and advised on follow-up and sanitary measures. This case is notable for the uncommon occurrence of Ascaris-induced intestinal obstruction in adults and the successful conservative management resulting in early worm expulsion.

The simultaneous occurrence of intestinal ascariasis and appendicitis presents a challenge in diagnosing pediatric abdominal emergencies due to overlapping symptoms. We present the case of an 8-year-old boy who experienced acute abdominal pain, characterized by a severe cramp in the mid and lower right abdomen, with pain rated 7 out of 10, a mild fever, and continuous nausea. The initial evaluation suggested appendicitis, supported by an Alvarado score of 9. However, ultrasonography did not conclusively confirm appendicitis but revealed an Ascaris worm in the ileum. This finding highlights the importance of careful diagnostic processes that combine clinical assessment with imaging techniques, while being mindful of their limitations. Surgical exploration confirmed retrocecal appendicitis coexisting with an Ascaris lumbricoides infection. The treatment involved surgical removal of the affected appendix and pharmacological expulsion of the parasitic worm using albendazole, which proved effective. This report emphasizes the consideration of ascariasis in diagnosing appendicitis, particularly in areas where intestinal parasites are common. It also demonstrated the improved diagnostic accuracy achieved through clinical scoring and imaging, thus reducing the risk of missing dual pathologies in young patients with acute abdominal pain.

OBJECTIVE
The objectives of this study are to assess the coronavirus disease (Covid) pre-pandemic and pandemic period table of 2019 with relation to the change in the frequency of ascariasis and to contribute to the epidemiological data in our nation.
METHODS
Data for this study were obtained from the Adana Provincial Directorate of Health, Department of Public Health Services between January 2017 and May 2022. Percentages of the number of cases were compared with the total numbers for the pre- and pandemic periods and for each specified period. Results were analyzed statistically.
RESULTS
When the number of scabies cases by year was analyzed, it was determined that the highest incidence rate was 37.8% in 2021 and the lowest incidence rate was 3.7% in 2017. During the pandemic period, it was determined that the rate of scabies in men was higher than that in women. Likewise, it was determined that the rate of scabies in women was higher than that in men before the pandemic. During the pandemic period, the rate of scabies in those aged 0, 1-4, 5-9, 10-14, and 65 years and over was higher than that before the pandemic.
CONCLUSION
According to our findings, the prevalence of scabies has increased throughout the Covid-2019 pandemic.

Philippine clinical laboratory licensing requirements mandate that diagnostic microscopy for Tuberculosis (TB) sputum microscopy, urinalysis, pap smears, wet smears, an option for complete blood count, stool exams, and malaria thick and thin smears should be accessible and available in health facilities including primary care centers. However, access to these essential diagnostics is hampered by the lack of trained personnel, relatively high costs for supplies and equipment especially in rural and underserved areas. This served as motivation for our team to utilize accessible resources in the form of affordable 3D printers, available CAD software, and components to build our low-cost Openflexure microscope (OFM) prototype. We successfully fabricated our prototype for a total of 310$ with a weight of 525g. We used pathology teaching slides from the Ateneo School of Medicine and Public Health and examined the OFM prototype imaging capabilities. The calculated image resolution was 13% higher compared to an LED light microscope sample captured by a mobile phone at 40x and 15% for 100x. The sampled slide images had adequate clarity with some identifiable cellular features for Rheumatic Heart Disease (RHD), Tuberculosis in soft tissue, and Ascariasis. We were able to correct the color aberrations of the OFM we built and was able to scan images up to 1000x magnification without using oil. Given the features and cost, the OFM prototype can be an attractive and affordable option as an alternative or augmentation to diagnostic microscopy in Philippine primary care. Moreover, it may enable telepathology to support diagnostic microscopy in frontline care.

Intestinal parasitic infections such as amoebiasis, ascariasis, hookworm infection, and are the most common infections among non-human primates (NHPs). There are always the possibilities of transmission these parasites between humans and NHPs. Multiple groups of rhesus macaques () live in the urban area of Kathmandu Valley near human settlements, however the gastrointestinal (GI) parasitic infections in those macaques are understudied. This study aimed to explore the GI parasites in free-ranging macaques from Pashupatinath, Swayambhunath, Tripureshwor, Nilbarahi temples and a group of captive rhesus macaques in the Central Zoo, Kathmandu. Fecal samples were collected from the macaques between October 2021 to September 2022 and assessed for parasites by the both wet mount method and concentration technique. There is high prevalence of GI parasite infection; out of 121 fecal samples examined, 87.6% of samples were positive. Six species of protozoans and eight species of helminths were identified from the fecal samples including the first report of in monkeys of Nepal. Among the protozoan parasites, (54.71%) showed the highest prevalence followed by (44.33%), (19.81%), and (10%). Among the helminths, spp. (31.13%) and spp. (31.13%) showed the highest prevalence followed by Hookworm (24.52%), and spp. (23.58%) The likelihood ratio test suggested that the prevalence differed significantly with the seasons for , spp., spp., Hookworm, and spp. The prevalence of , , spp. spp. and Unknown spp.1 differed with sampling localities. The high prevalence of GI parasites found in the macaques living in the densely urbanized Kathmandu presents a potential threat to humans and warrants further study as well as increased education of the public and management of the human-macaque interface in the urban landscape of the Valley.

BACKGROUND
Neglected tropical diseases (NTDs) affect most impoverished communities in developing countries, like Myanmar in Southeast Asia. NTDs have been understudied and underreported in Myanmar.
METHODS
A systematic review of published and grey literature (1900-2023) on neglected tropical diseases (NTDs) in Myanmar was conducted. The literature search included five international databases: PubMed, EMBASE, Ovid Global Health, and Web of Science Core Collection and one national database: the Myanmar Central Biomedical Library (locally published papers and grey literature). The selection criteria included articles with all types of study designs of current or previous infections conducted in humans, that reported NTDs, recognised by WHO, US CDC, and listed in PLoS NTDs. We included melioidosis and rickettsioses which we consider also meet the definition of an NTD.
RESULTS
A total of 5941 records were retrieved and screened, of which, 672 (11%) met the selection criteria and were included in this review. Of the included articles, 449 (65%) were published after 2000 and 369 (55%) were from two regions (Yangon and Mandalay) of Myanmar. Of the included articles, 238 (35%) reported bacterial NTDs, 212 (32%) viral NTDs, 153 (23%) helminth NTDs, 25 (4%) protozoal NTDs and 39 (6%) reported more than one aetiology. Based on reported frequency in descending order, the bacterial NTDs were leprosy, Escherichia coli enteritis, salmonellosis, cholera, shigellosis, melioidosis, leptospirosis and rickettsioses; the viral NTDs were dengue, chikungunya and Japanese encephalitis virus (JEV) infection; the protozoal NTDs were amoebiasis, giardiasis and leishmaniasis, and the helminth NTDs were ascariasis, trichuriasis, hookworm disease, filariasis and strongyloidiasis.
CONCLUSION
This review summarises NTDs reported in Myanmar over the past 100 years. The findings suggest that most NTDs are likely to be under reported, especially from the majority of the country which is far from academic centres. Research capacity building together with strengthening of laboratory systems would lead to better understanding of the true burden of NTDs in Myanmar.

BACKGROUND
Ascariasis is a common disease in humans and pigs. In previous reports, it has been known that ascariasis in humans is not only caused by but also by which is known to originate from pigs.
AIMS AND OBJECTIVES
This research aims to identify the species of that infect traditional pig farmers in Bali, Indonesia.
MATERIALS AND METHODS
To achieve this, an observational study was conducted, in which 239 feces samples were collected from traditional pig farmers. The collected samples were then divided into two parts, with one part stored in a pot containing 10% formalin for microscopic testing, and the other part stored in 70% ethanol for molecular testing. In cases where infection was observed during the microscopic examination, a further test was conducted using the polymerase chain reaction (PCR) method for molecular examination. The DNA derived from the PCR was then subjected to DNA sequencing.
RESULTS
The result was compared to gene data previously published in the Gene Bank. The results of the microscopic examination showed that 22 farmers were infected with Ascaris. However, PCR testing and DNA sequencing indicated that three infections were caused by .
CONCLUSION
Therefore, it can be concluded that is a zoonosis in Bali. Thus, efforts to control ascariasis must pay attention to the presence of pigs around it. Handling of ascariasis is not only carried out in humans but also in pigs and the environment.

BACKGROUND
Intrabiliary ascariasis is an uncommon cause of biliary colic and obstructive jaundice among children due to the small size of the ampullary orifice. A high index of suspicion for patients living in an endemic area and radiologic examination are crucial for diagnosis and treatment.
CASE PRESENTATION
A 12-year-old male Ethiopian child presented with colicky right upper quadrant pain, nausea, and vomiting for 3 days. Physical examination showed slightly icteric sclera and slightly tender hepatomegaly. Laboratory and ultrasound examinations were suggestive of obstructive jaundice secondary to intra-biliary ascariasis. The child was admitted and followed by conservative management including maintenance fluid, nil per mouth, and analgesics. The abdominal pain and icterus resolved on his second and third day of admission, respectively. A follow-up ultrasound showed that the worm had migrated from the common bile duct. The patient was dewormed with a single dose of oral albendazole 400mg and discharged home. Currently, the patient is well and attending school.
CONCLUSION
Although biliary ascariasis is an uncommon cause of acute abdomen and obstructive jaundice, it should be suspected among patients from endemic areas presenting with suggestive clinical and laboratory features. Conservative treatment is the treatment of choice for uncomplicated biliary ascariasis patients.

The aim of the present study was to assess morphologic and genetic data on ascariasis in swine (Sus scrofa domesticus) and humans in low-resource rural and periurban communities in the state of Piauí, Brazil. Our cross-sectional survey included 100 fecal samples obtained from swine and 682 samples from humans. Fifteen pigs were necropsied. Human and porcine fecal samples were examined to identify Ascaris eggs. Parasites obtained in the swine necropsies were studied using scanning electron microscopy (SEM), and the mitochondrial gene encoding the cytochrome oxidase 1 (cox1) enzyme was partially amplified and sequenced for molecular taxonomy and phylogenetic analyses. The overall prevalence of Ascaris eggs in the swine fecal samples was 16/100 (16%). No Ascaris eggs were identified in the human fecal samples. SEM of six worms recovered from pigs demonstrated morphological characteristics of A. suum. Cox1 sequences were compatible with A. suum reference sequences. Original and reference (GenBank) nucleotide sequences were organized into clusters that did not segregate the parasites by host species or and region. The largest haplogroups were dominated by haplotypes H01, H02 and H31. In the communities studied, there was no epidemiological evidence of the zoonotic transmission of ascariasis at the human-swine interface.

Review
Ascariasis and intestinal parasitic nematodes are the leading cause of mass mortality infecting many people across the globe. In light of the various deleterious side effects of modern chemical-based allopathic drugs, our preferences have currently shifted towards the use of traditional plant-based drugs or botanicals for treating diseases. The defensive propensities in the botanicals against parasites have probably evolved during their co-habitation with parasites, humans and plants in nature and hence their combative interference in one another's defensive mechanisms has occurred naturally ultimately being very effective in treating diseases. This article broadly outlines the utility of plant-based compounds or botanicals prepared from various medicinal herbs that have the potential to be developed as effective therapies against the important parasites causing ascariasis and intestinal hookworm infections leading to ascariasis & infections and thereby human mortality, wherein allopathic treatments are less effective and causes enormous side-effects.
