Eosinophilic enteritis (EoN) poses a distinctive challenge, affecting individuals with various clinical presentations depending on the layer and extent of the bowel wall. We present a case of a 19-year-old female with abdominal pain, vomiting, and loose stools for 1 month. Labs were significant for persistent leukocytosis with peripheral eosinophilia. A computed tomography of the abdomen/pelvis demonstrated moderate abdominal ascites and moderately diffuse mucosal thickening of jejunal loops. A diagnostic paracentesis unveiled low serum ascites albumin gradient and 92% eosinophils. Push enteroscopy resulted in no significant biopsy findings, though a laparoscopic full-thickness jejunal biopsy exhibited increased eosinophils in the bowel wall. Intravenous steroid, proton pump inhibitor, and dietary changes resolved the symptoms and normalized the labs within a week. Our case report highlights a variable presentation of eosinophilic jejunitis uncommon in this disease population. EoN is an easily missed diagnosis and mandates frequent follow-up to prompt relevant investigations. Atopic clinical features are not prevalent in each case. While rare, EoN requires a strong clinical suspicion, even if endoscopic biopsies are unremarkable, prompting timely laparoscopic full-thickness biopsy. Per protocol, physicians must do the infectious and eosinophilia workup to rule out other etiologies. Our case also highlights that worsening clinical condition in EoN warrants early intravenous steroids with a favorable prognosis and considers a psychosocial aspect of the disease on the patient's health.

BACKGROUND
Ovarian cancer is the first cause of death from gynecological malignancies mainly due to development of chemoresistance. Despite the emergence of PARP inhibitors, which have revolutionized the therapeutic management of some of these ovarian cancers, the 5-year overall survival rate remains around 45%. Therefore, it is crucial to develop new therapeutic strategies, to identify predictive biomarkers and to predict the response to treatments. In this context, functional assays based on patient-derived tumor models could constitute helpful and relevant tools for identifying efficient therapies or to guide clinical decision making.
METHOD
The OVAREX study is a single-center non-interventional study which aims at investigating the feasibility of establishing in vivo and ex vivo models and testing ex vivo models to predict clinical response of ovarian cancer patients. Patient-Derived Xenografts (PDX) will be established from tumor fragments engrafted subcutaneously into immunocompromised mice. Explants will be generated by slicing tumor tissues and Ascites-Derived Spheroids (ADS) will be isolated following filtration of ascites. Patient-derived tumor organoids (PDTO) will be established after dissociation of tumor tissues or ADS, cell embedding into extracellular matrix and culture in specific medium. Molecular and histological characterizations will be performed to compare tumor of origin and paired models. Response of ex vivo tumor-derived models to conventional chemotherapy and PARP inhibitors will be assessed and compared to results of companion diagnostic test and/or to the patient's response to evaluate their predictive value.
DISCUSSION
This clinical study aims at generating PDX and ex vivo models (PDTO, ADS, and explants) from tumors or ascites of ovarian cancer patients who will undergo surgical procedure or paracentesis. We aim at demonstrating the predictive value of ex vivo models for their potential use in routine clinical practice as part of precision medicine, as well as establishing a collection of relevant ovarian cancer models that will be useful for the evaluation of future innovative therapies.
TRIAL REGISTRATION
The clinical trial has been validated by local research ethic committee on January 25th 2019 and registered at ClinicalTrials.gov with the identifier NCT03831230 on January 28th 2019, last amendment v4 accepted on July 18, 2023.

Ascites can manifest as a result of many conditions, with cirrhosis being the most common cause in the United States. Here, we present a case of lymphocytic ascites, a less common variant that occurred due to infection with Chlamydia trachomatis. This was a 37-year-old female with a history of substance and sexual abuse who presented with the chief complaints of abdominal pain, abdominal distension, and weight gain. She was febrile on admission with a distended, tender abdomen. The more common cardiac, renal, and hepatic causes were ruled out with extensive workup. Diagnosis and therapeutic paracentesis were done with fluid analysis significant for lymphocyte predominance and absence of malignant cells. Multi-modal imaging had ruled out suspicious malignant masses but CT abdomen/pelvis did show complex large volume ascites. Urine chlamydia and gonorrhea polymerase chain reaction (PCR) had resulted positive for chlamydia, leading us to start Doxycycline. Other infectious workups were negative, but ascitic fluid chlamydia NAAT was positive. Though initially worsening, the patient started showing significant clinical improvement after starting doxycycline, with the resolution of ascites and associated symptoms. This case report intends to bring to attention the importance of testing for chlamydia infection in cases of lymphocytic ascites, especially in sexually active females.

Therapeutic Advances in Medical Oncology 2024Bacterial peritonitis (BP) in patients with gastrointestinal (GI) cancer has been poorly described, and its prevalence is unknown.
BACKGROUND
Bacterial peritonitis (BP) in patients with gastrointestinal (GI) cancer has been poorly described, and its prevalence is unknown.
OBJECTIVES
This study aimed to evaluate in patients with both GI cancer and ascites the prevalence of BP, associated features, mechanisms, prognosis, and the diagnostic performance of neutrophil count in ascites.
DESIGN
A retrospective, multicenter, observational study.
METHODS
All patients with GI cancer and ascites who underwent at least one paracentesis sample analyzed for bacteriology over a 1-year period were included. BP was defined by a positive ascites culture combined with clinical and/or biological signs compatible with infection. Secondary BP was defined as BP related to a direct intra-abdominal infectious source.
RESULTS
Five hundred fifty-seven ascites from 208 patients included were analyzed. Twenty-eight patients had at least one episode of BP and the annual prevalence rate of BP was 14%. Among the 28 patients with BP, 19 (65%) patients had proven secondary BP and 17 (59%) patients had multi-microbial BP, mainly due to . A neutrophil count greater than 110/mm in ascites had negative and positive predictive values of 96% and 39%, respectively, for the diagnosis of BP. The median survival of patients with BP was 10 days (interquartile range 6-40) after the diagnosis.
CONCLUSION
BP is not rare in patients with GI cancer and is associated with a poor short-term prognosis. When a patient with GI cancer is diagnosed with BP, a secondary cause should be sought. Further studies are needed to better define the best management of these patients.

BACKGROUND
Competency in paracentesis is an important procedural skill for health care practitioners caring for patients with decompensated cirrhosis. It is estimated that 97,577 paracentesis procedures were performed between 2010 and 2012 across 120 academic medical centers and 290 affiliated hospitals.
METHODS
Due to limitations of resources at the Central Texas Veterans Affairs Hospital, a paracentesis clinic was created to give patients improved access to this procedure which is staffed by a supervising physician and internal medicine residents. We evaluated resident competency via survey and change in the number of paracentesis procedures performed with the utilization of this clinic.
RESULTS
Thirty-three residents completed the survey. The total mean number of paracentesis sessions participated in was 4.8. It was found that during training, 79% met conditional independence in performing this procedure with a high level of comfort by rotating through this clinic. It was also found that the number of procedures performed by internal medicine residents significantly increased with the addition of this clinic.
CONCLUSIONS
A dedicated paracentesis clinic with internal medicine resident involvement can increase resident paracentesis procedural independence, the number of procedures available and performed, and procedural comfort level by the end of training.

Clinics (Sao Paulo, Brazil) 2024This study aims to quantify bedside pleural procedures performed at a quaternary teaching hospital describing technical and epidemiological aspects.
BACKGROUND AND OBJECTIVE
This study aims to quantify bedside pleural procedures performed at a quaternary teaching hospital describing technical and epidemiological aspects.
MATERIALS AND METHODS
The authors retrospectively reviewed consecutive patients who underwent invasive thoracic bedside procedures between March 2022 and February 2023.
RESULTS
463 chest tube insertions and 200 thoracenteses were performed during the study period. Most procedures were conducted by 1st-year Thoracic Surgery residents, with Ultrasound Guidance (USG). There was a notable preference for small-bore pigtail catheters, with a low rate of immediate complications.
CONCLUSION
Bedside thoracic procedures are commonly performed in current medical practice and are significant in surgical resident training. The utilization of pigtail catheters and point-of-care ultrasonography by surgical residents in pleural procedures is increasingly prevalent and demonstrates high safety.

Abdominal paracentesis is a commonly performed bedside procedure. It serves as a therapeutic and diagnostic tool for a variety of conditions. It is regarded as a safe procedure with a low risk of complications. Rarely, iatrogenic complications such as peritonitis, haemorrhage, and bowel perforation may occur. Intraperitoneal haemorrhage is rare and usually occurs due to bleeding from the intraabdominal venous collateral vessels or mesenteric varices. However, intraperitoneal haemorrhage secondary to injury to the abdominal wall arteries, such as the inferior epigastric artery or deep circumflex iliac artery (DCIA), is very uncommon. We report on a 64-year-old man with decompensated cardiac failure who underwent paracentesis due to gross ascites. Twenty-four hours post-procedure, he became progressively hypotensive and lethargic. An ecchymosis measuring 3 cm × 2 cm was seen over the puncture site. An urgent CT angiography of the abdomen showed a large left-sided intraperitoneal haematoma with active contrast extravasation from the left DCIA. We performed a successful angioembolisation of the left DCIA. It is important to note that intraperitoneal haemorrhages secondary to DCIA injury may present as occult intraperitoneal haemorrhage. Angioembolisation is a useful tool in the management of uncontrolled intraperitoneal haemorrhage. The recommended puncture site is in the left lower quadrant, 2-4 cm superior and medial to the anterior superior iliac spine (ASIS). This case report serves to emphasise the rare but potentially lethal complication of a commonly performed procedure. A high index of suspicion of intraperitoneal haemorrhage is required for patients with unexplained hypotension post-paracentesis, even if overt abdominal signs are absent. The use of ultrasound guidance will aid in reducing the risk of severe complications and increasing the overall success rate.

Medical thoracoscopy with chemical pleurodesis is a last resort for managing patients who suffer. from recurrent hepatic hydrothorax. However, despite pleurodesis, the rapid fluid build-up can hinder the successful apposition of the pleural surfaces. To improve the chances of success, we investigated the effectiveness of abdominal paracentesis before chemical pleurodesis via medical thoracoscopy to reduce significant fluid shifts from the peritoneal to the pleural cavity. We present a series of three patients with liver cirrhosis complicated by hepatic hydrothorax who underwent medical thoracoscopy with talc pleurodesis. Before the procedure, we optimised medical treatment, and if needed, we performed large-volume paracentesis to prevent rapid reaccumulation of pleural fluid. All study subjects achieved treatment success, defined as relief of breathlessness and absence of pleural effusion at 12 months. Complications related to the treatment included hepatic encephalopathy and acute kidney injury, which were managed conservatively. To manage symptomatic and recurrent hepatic hydrothorax, medical thoracoscopy with talc pleurodesis, preceded by the evacuation of ascites, can be considered as a treatment option. This procedure should be considered early for those who do not respond to medical management and are not suitable candidates for TIPS or liver transplantation.

A 59-year-old woman with polycythemia vera-related portal hypertension requiring frequent paracentesis was admitted for asymptomatic recurrent spontaneous bacterial peritonitis, which was diagnosed based on elevated polymorphonuclear (PMN) count. She had multiple similar admissions during which she was treated with antibiotics. The patient had chronic baseline leukocytosis due to polycythemia vera. Repeat paracentesis after intravenous antibiotics demonstrated persistent elevation of PMN count without clinical symptoms. A multidisciplinary team concluded that the increased PMN count was secondary to polycythemia. The patient was diagnosed with omental extramedullary hematopoiesis, a rare condition causing elevated PMN count in the absence of bacterial contamination.

AIM OF THE STUDY
Early paracentesis before antibiotic administration reduces morbidity and mortality in patients with decompensated cirrhosis. We studied the association of variables with antibiotic administration before or after performing paracentesis.
MATERIAL AND METHODS
This was a retrospective study of 137 patients with ascites secondary to cirrhosis admitted to a community hospital in New York City. Predictor variables were demographic, disease-related, admission timing, and serum measurement.
RESULTS
We found a significantly increased relative risk for performing paracentesis after antibiotic administration for those admitted at night (relative risk ratio [RRR] = 3.01, 95% CI: 1.02-8.85, = 0.046). Demographic, disease-related, and serum measurement variables were not significantly associated with performing paracentesis or order of antibiotic administration. Also, increased body mass index was significantly associated with decreased relative risk for paracentesis not done (RRR = 0.84, 95% CI: 0.74-0.96, = 0.01).
CONCLUSIONS
In conclusion, there was increased relative risk for performing paracentesis after antibiotic administration for patients admitted at night. We recommend ongoing resident and hospitalist training to maintain competency in bedside procedures such as paracentesis for patients with cirrhosis. Also, increased staffing or the presence of a resident/hospitalist led interventional team during night shifts may also help optimize the rates of timely paracentesis.
