In clinical practice, the typical approach to ingested foreign bodies in stable patients involves expectant management, as most materials pass through the gastrointestinal (GI) tract without adverse effects. However, foreign bodies that travel through the appendix's lumen can cause acute appendicitis due to their inability to exit the colon. Rarer causes of appendicitis include parasitic infiltration by . The wandering behavior of within the GI tract can lead to various surgical complications in the abdomen. Occasionally, these parasites can migrate to the vermiform appendix, where they may either induce pathological changes or remain asymptomatic. We report an unusual case of an eight-year-old Pakistani female patient who presented to the emergency room with pain in the right iliac fossa, associated with anorexia and nausea, for one day. On examination, the patient was found to be vitally stable, with right iliac fossa tenderness noted on palpation. Additionally, the patient exhibited positive pointing, rebound, Rovsing, and psoas signs. Her medical history revealed that she had ingested a metallic needle seven months ago. Blood tests were undertaken, and an abdominal X-ray confirmed the existence of a radiopaque metallic object in the right lower quadrant of the abdomen. The patient underwent an open appendicectomy for acute appendicitis and was discovered to have a metallic needle lodged in the vermiform appendix. Concurrently, she also had ascariasis, as she vomited a 23-cm-long worm. It is important to consider both mechanical and parasitic etiologies in diagnosing acute appendicitis; detailed evaluation and management strategies are necessary to address these unique etiologies effectively.

Ascariasis is a common helminthic infection, especially in India. Though it is known to inhabit the jejunum of the small intestine, it may invade the hepato-biliary and pancreatic ducts, causing a spectrum of clinical manifestations. We present a case of idiopathic recurrent acute pancreatitis in a 61-year-old female patient who was later diagnosed with pancreatic ascariasis using endoscopic ultrasound. This emphasizes the possibility of ascariasis as one of the causes of acute pancreatitis and the use of endoscopic ultrasound as an initial diagnostic tool for the evaluation of idiopathic acute pancreatitis.

Meta-Analysis
Soil-transmitted Helminth (STH) infections have been found associated with people living with human immunodeficiency virus (HIV) but little is known about the overall burden of STH coinfection in HIV patients. We aimed to assess the burden of STH infections among HIV patients. Relevant databases were systematically searched for studies reporting the prevalence of soil-transmitted helminthic pathogens in HIV patients. Pooled estimates of each helminthic infection were calculated. The odds ratio was also determined as a measure of the association between STH infection and the HIV status of the patients. Sixty-one studies were finally included in the meta-analysis, consisting of 16,203 human subjects from all over the world. The prevalence of Ascaris lumbricoides infection in HIV patients was found to be 8% (95% CI 0.06, 0.09), the prevalence of Trichuris trichiura infection in HIV patients was found to be 5% (95% CI 0.04, 0.06), the prevalence of hookworm infection in HIV patients was found to be 5% (95% CI 0.04, 0.06), and prevalence of Strongyloides stercoralis infection in HIV patients was found to be 5% (95% CI 0.04, 0.05). Countries from Sub-Saharan Africa, Latin America & Caribbean and Asia were identified with the highest burden of STH-HIV coinfection. Our analysis indicated that people living with HIV have a higher chance of developing Strongyloides stercoralis infections and decreased odds of developing hookworm infections. Our findings suggest a moderate level of prevalence of STH infections among people living with HIV. The endemicity of STH infections and HIV status both are partially responsible for the burden of STH-HIV coinfections.

KEY CLINICAL MESSAGE
This case report highlights the importance of considering parasitic infections, particularly Ascaris lumbricoides, as a possible cause of acute pancreatitis in children, especially in endemic regions. Noninvasive imaging techniques, such as ultrasonography, can play a crucial role in the early detection and diagnosis of this unusual presentation. Timely administration of anthelmintic therapy led to the resolution of symptoms and prevented the need for invasive procedures. Healthcare providers should be vigilant about the diverse clinical manifestations of ascariasis, and regular deworming programs and health education are essential in minimizing the burden of this neglected tropical disease among children.
ABSTRACT
Ascariasis is a common public health problem globally but it is more prevalent in school-age children and it often goes undiagnosed, leading to severe complications. The purpose of this report is to spread awareness of its unusual presentation and how to judiciously use noninvasive approaches for its diagnosis. We present a case of a 10-year-old girl that was presented in pediatric emergency with gradually worsening epigastric pain. Initial lab work-up showed elevated pancreatic enzymes which lead to the diagnosis of acute pancreatitis. The patient was managed in the line of acute pancreatitis and with further evaluation by imaging techniques such as ultrasound and CT-scan abdomen, Ascaris lumbricoides (A. lumbricoides) was visualized. She was then treated with prophylactic antibiotics and antiparasitic medications, which resolved her symptoms and the child responded to the treatment. In children, parasites should be considered as a cause of acute pancreatitis by clinicians, especially in low-income countries, and before performing invasive procedures, noninvasive approaches should be considered as an initial option. This can save the patient from multiple invasive procedure and its severe complications.

BACKGROUND
Soil-transmitted helminthiasis (STH) refers to a set of parasitic illnesses caused by nematode worms and spread to people through faeces-contaminated soil. It is highly prevalent in low- and middle-income countries due to a lack of environmental sanitation and personal hygiene. Pregnant women are among the risk groups for infection by soil-transmitted helminths. Former studies of the disease burden among pregnant women in Ethiopia didn't indicate the intensity of parasitic infection. The aim of this study was to assess the prevalence and associated factors of soil-transmitted helminths among pregnant women.
METHODS
An institution-based cross-sectional study was conducted among 416 randomly selected pregnant women. The data were collected using a structured interview-administered questionnaire and a laboratory test. The Kato-Katz technique was used to diagnose soil-transmitted helminthiasis and determine the intensity of the infection. The collected data were entered into Epi-Data version 4.6 and exported to SPSS version 25 for analysis. Multivariate logistic regression analysis was used to identify independent predictors of soil-transmitted helminths at a p-value < 0.05.
RESULTS
The overall prevalence of soil-transmitted helminths among pregnant women was 30%. (95%, CI: 26-34%). Living in a rural area (AOR = 3.35; 95% CI = 1.83-6.13), drinking from an unprotected water source (AOR = 2.52; 95% CI = 1.45-4.37), not washing one's hand after the toilet (AOR = 2.75; 95% CI = 1.55-4.88), lacking health information (AOR = 1.70; 95% CI = 1.01-2.85), working as a daily labourer (AOR = 2.88; 95% CI = 1.01-8.20), and walking barefoot (AOR = 4.00; 95% CI = 2.29-7.00) were significantly associated with the presence of soil-transmitted helminths among pregnant women.
CONCLUSION
The prevalence of STH was significantly moderate in the study area, where pregnant women were mostly affected by ascariasis and hookworms. Living in a rural area, being a daily labourer, walking barefoot, not washing hands after the toilet, drinking from an unprotected water source, and lacking health information were the determining factors. Interventions including health education, the expansion of pure drinking water sources, the promotion of personal hygiene, and the wearing of shoes are recommended to reduce the burden of soil-transmitted helminths in the study area.

Ascariasis (roundworm) is the most common parasitic helminth infection globally and can lead to significant morbidity in children including chronic lung disease. Children become infected with Ascaris spp. via oral ingestion of eggs. It has long been assumed that Ascaris egg hatching and larval translocation across the gastrointestinal mucosa to initiate infection occurs in the small intestine. Here, we show that A. suum larvae hatched in the host stomach in a murine model. Larvae utilize acidic mammalian chitinase (AMCase; acid chitinase; Chia) from chief cells and acid pumped by parietal cells to emerge from eggs on the surface of gastric epithelium. Furthermore, antagonizing AMCase and gastric acid in the stomach decreases parasitic burden in the liver and lungs and attenuates lung disease. Given Ascaris eggs are chitin-coated, the gastric corpus would logically be the most likely organ for egg hatching, though this is the first study directly evincing the essential role of the host gastric corpus microenvironment. These findings point towards potential novel mechanisms for therapeutic targets to prevent ascariasis and identify a new biomedical significance of AMCase in mammals.

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.

INTRODUCTION
Soil-transmitted helminthiasis (STH) are a major public health problem in Sub-Saharan Africa. In Kenya, the National School Based Deworming Program (NSBDP) was launched in 2012 with a goal of reducing STH prevalence in school-aged children (SAC) to <1%, however monitoring and evaluation results have consistently showed > 20% prevalence in Narok County. We conducted a study to investigate factors associated with STH infections among SAC in Narok County.
METHODOLOGY
A cross-sectional study was conducted among 514 SAC from five schools in Trans Mara West sub-county, Narok County. The sub-county was selected because it had participating schools within the NSBDP with a high prevalence of STH infection. Participants were selected using systematic random sampling. Stool samples collected from participants were examined for STH eggs using Kato-Katz technique. An open data kit questionnaire was used to collect socio-demographics, household, and STH knowledge information from 139 of the 514 SAC. Descriptive statistics was used to summarize the data, prevalence and mean intensity of infections were calculated, and logistic regression used to determine factors associated with STH infections.
RESULTS
The overall prevalence of any STH infection was 24.6% (95%CI: 21.1-28.6). Trichuris trichiura 14.4% (95%CI: 11.7-17.8), Ascaris lumbricoides 12.5% (95%CI: 9.9-15.7) and hookworm 0%. From multivariable analysis the only factors significantly associated with increased risk of STH infection were, children attending Karda and Nkarano schools with aOR = 5.29 (95%CI: 1.45-19.24); p = 0.011 and aOR = 4.53 (95%CI: 1.29-15.97); p = 0.019 respectively. For A. lumbricoides, children attending Nkarano School were associated with a significant risk of infection with aOR = 7.81 (95%CI: 1.81-33.63); p = 0.006.
CONCLUSIONS
Despite the ongoing work of NSBDP, the STH prevalence is still ≥ 20% in Trans Mara West sub-county Narok County, among SAC. This underscores the need for continued annual MDA. Additionally, if possible, drug combinations may effectively manage T. trichiura, the region's most common helminth. The study found a correlation between children attending specific schools and STH infection risk, suggesting the importance of health education and improved water, sanitation, and hygiene practices holistically both in schools and associated catchment areas that can act as STH reservoirs to alleviate the burden of STH.
