Neuroendocrine carcinomas (NECs) of the gallbladder are very rare and aggressive tumors with poor prognosis. Most of them are poorly differentiated and belong to the small cell type. We report a case of a 59-year-old woman who presented with abdominal pain and distension. Contrast-enhanced computed tomography revealed a large heterogeneous mass in the liver, adjacent to the gallbladder, and omental nodules. CA 19-9 level was elevated and ascitic fluid cytology was suspicious for malignancy. Percutaneous biopsy of the liver mass confirmed the diagnosis of small cell NEC of the gallbladder. The patient was considered inoperable and planned for chemotherapy, but she died 20 days after admission. This case illustrates the diagnostic challenges and the dismal outcome of small cell NEC of the gallbladder. Early detection and multimodal treatment are essential for improving the survival of these patients.

Review
BACKGROUND Peritoneal dialysis (PD) serves as a critical renal replacement therapy for individuals with end-stage renal disease (ESRD), leveraging the peritoneum for fluid and substance exchange. Despite its effectiveness, PD is marred by complications such as peritonitis, which significantly impacts patient outcomes. The novelty of our report lies in the presentation of a rare case of PD-associated peritonitis caused by 2 unusual pathogens, emphasizing the importance of rigorous infection control measures. CASE REPORT We report on an 80-year-old African-American female patient with ESRD undergoing PD, who was admitted twice within 8 months for non-recurring episodes of peritonitis. These episodes were attributed to the rare pathogens Achromobacter denitrificans/xylosoxidans and Carbapenem-resistant Acinetobacter baumannii. Despite presenting with similar symptoms during each episode, such as abdominal pain and turbid dialysis effluent, the presence of these uncommon bacteria highlights the intricate challenges in managing infections associated with PD. The treatment strategy encompassed targeted antibiotic therapy, determined through susceptibility testing. Notably, the decision to remove the PD catheter followed extensive patient education, ensuring the patient comprehended the rationale behind this approach. This crucial step, along with the subsequent shift to hemodialysis, was pivotal in resolving the infection, illustrating the importance of patient involvement in the management of complex PD-related infections. CONCLUSIONS This case underscores the complexities of managing PD-associated peritonitis, particularly with uncommon and resistant bacteria. It emphasizes the importance of rigorous infection control measures, the need to consider atypical pathogens, and the critical role of patient involvement in treatment decisions. Our insights advocate for a more informed approach to handling such infections, aiming to reduce morbidity and improve patient outcomes. The examination of the literature on recurrent peritonitis and treatment strategies provides key perspectives for navigating these challenging cases effectively.

BACKGROUND
Portal hypertension commonly occurs due to liver cirrhosis, and esophageal varices (EV) is one of the major complications associated with it. The most common cause of death in liver cirrhosis is EV bleeding. Hence, GE screening for EV is required, which is an invasive procedure. Regular use of endoscopy results in low compliance due to cost and discomfort for patients. Hence, identifying non-invasive markers that could grade EV provides a useful screening tool for family physicians and primary health centers (PHCs) by referring the patient to higher centers for definitive treatment, which could reduce mortality due to variceal bleeding in cirrhotic patients.
AIMS
To assess non-invasive predictors of grade EV in patients diagnosed with liver cirrhosis.
SETTINGS AND DESIGN
Cross-sectional study.
METHODS AND MATERIAL
A total of 109 patients with liver cirrhosis underwent clinical and biochemical evaluation, USG abdomen with spleen bipolar diameter, ascitic fluid analysis, and upper GE with a grade of EV are recorded.
STATISTICAL ANALYSIS USED
SPSS software with Student -test, Chi-square -test, analysis of variance, receiver operator characteristic (ROC) curves, and Spearman correlation with 95% CI is used. <0.05 is considered significant.
RESULTS
Aminotransferase to Platelet count Ratio Index (APRI) score >1.815, PC/SD ≤909, and SAAG >1.1g/dl showed EV in liver cirrhosis ( < 0.05). The order of prediction with ROC curves shows APRI score > PC/SD > SAAG. In grading EV, APRI scores of 1.9-2.5 and >2.5 showed small and large EV, respectively ( < 0.05).
CONCLUSIONS
APRI score may be used in PHC as an early intervention to grade EV and refer the patient to higher centers for definitive treatment. This would prevent the progression of varices to rupture and reduce mortality due to variceal bleeds in liver cirrhosis patients.

Heterotopic pregnancy (HP) is the coexistence of living or dead intrauterine pregnancy, single or multiple, and extrauterine pregnancy located in the oviduct, ovary, uterine corner, cervix or peritoneal cavity. This condition is very rare (1:30 000 pregnancies). HP constitutes a rare obstetric condition. Its occurrence after natural conception is sparsely documented in the literature. Here in, we present a case of a 27-year-old primeparous women who presented at 18 weeks with features of ruptured ectopic pregnancy. Initial ultrasonographic imaging showed an intrauterine pregnancy corresponding to 18 weeks. It also revealed a floating fetus with significant collection of fluid in the pouch of Douglas, retroceacal recess and both hepatocellular recess. An emergency explorative laparotomy was done where right salpingectomy was performed. She was later followed up to term and delivered by elective cesarean section successfully. A brief narrative of the challenges in the management, clinical presentation and limitation in the management is highlighted in the present case report. Heterotopic pregnancy can occur in natural conception irrespective of usage of ovulation induction. Routine early pregnancy ultrasound can promote early detection with prompt surgical intervention to mitigate its complications.

Peritoneal dialysis (PD)-associated peritonitis is a common complication of PD. Enteric peritonitis is defined as peritonitis arising from an intestinal or intra-abdominal organ source. The delay in the diagnosis or treatment of enteric peritonitis has been reported to increase mortality. Therefore, the early consideration of enteric peritonitis, particularly in cases of culture-negative peritonitis, is imperative. A 67-year-old Japanese man who had been undergoing PD for 3 years, was admitted to our hospital with a diagnosis of PD-associated peritonitis. A month previously, he experienced a bleeding gastric ulcer, which led to severe anemia (hemoglobin 6.3 mg/dL), followed by thrombocytosis. On admission, peritoneal fluid analysis showed a high white blood cell count (WBC: 8,570 /µL), with neutrophils predominating (74.5%). Cultures of both his dialysis effluent and blood were negative. After admission, the WBC count of the dialysis effluent gradually decreased alongside antibiotic therapy, but the patient's abdominal pain did not improve. After 4 days, enhanced computed tomography showed superior mesenteric artery (SMA) thrombosis and intestinal necrosis. Therefore, emergency intestinal resection and PD catheter removal were performed, and then antithrombosis therapy was initiated. Because the patient's abdominal pain was improved and platelet count and D-dimer concentration were reduced by these treatments, he was discharged from the hospital after 47 days. Thus, we report a rare case of culture-negative PD-associated peritonitis, which was caused by SMA thrombosis and intestinal necrosis. It is likely that combination of severe calcification of SMA and prolonged thrombocytosis secondary to the severe anemia contributed to the thrombosis.

Progressive multifocal leukoencephalopathy (PML), a severe demyelinating disease of the central nervous system, is caused by the reactivation of the polyomavirus JC virus (JCV). It favors the cerebrum and typically occurs in patients with immunodeficiencies, with a progressive course and fatal outcome in the majority of cases. However, the cerebellar form of PML, characterized by isolated posterior fossa lesions, such as those in the cerebellum or brainstem at disease onset, is rare, and reports of its occurrence in peritoneal dialysis (PD) patients are lacking. In this paper, we describe a rare case of a cerebellar form of PML in a PD patient. A 64-year-old man undergoing PD was referred to our hospital for anorexia, nausea, and vomiting in the past month. He had finger-to-nose test abnormalities, gaze-directed nystagmus, and scanning speech. He was diagnosed with the cerebellar form of PML based on his progressive cerebellar symptoms, the typical magnetic resonance imaging findings, and the presence of JCV-DNA in the cerebrospinal fluid polymerase chain reaction test. He developed nocturnal delirium, aggravated disquiet, and died of pneumonia on the 69th day. Clinicians should consider the cerebellar form of PML as a differential diagnosis if PD patients develop progressive cerebellar symptoms.

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.

Bladder metastasis of gastric adenocarcinoma is a rare phenomenon. Hereby, we report a case of a 52-year-old patient who presented with upper gastro-intestinal bleeding and ascites and was diagnosed with gastric signet-ring cell carcinoma. A CT scan revealed peritoneal infiltration and anterior parietal thickening of bladder wall. Cystoscopy showed three budding lesions of the anterior wall of the bladder. He had an endoscopic resection. Histology concluded that the bladder was infiltrated by a poorly differentiated carcinoma with independent cells consistent with a gastric origin. The patient was to be treated with palliative chemotherapy.

BACKGROUND
Peritoneal metastases (PM) commonly occur in colorectal cancer patients. Systemic chemotherapy yields poor outcomes for these patients. It is hypothesised that traditional systemic chemotherapy is not very effective for this patient population. This study investigates to what extent systemic anti-cancer therapy crosses the peritoneal barrier.
METHODS
In a Phase I study, eighteen patients received systemic oxaliplatin, 5-FU, and bevacizumab. Plasma and peritoneal fluid samples were collected to measure drug concentrations. A non-compartmental analysis determined the Area Under the Curve (AUC) for oxaliplatin and 5-FU in both matrices. Intraperitoneal (IP) and intravenous (IV) exposure ratios were calculated, along with the bevacizumab concentration IP/IV ratio. The relationship between tumour load and IP/IV ratios and the correlation between the IP/IV ratios of different treatments were assessed statistically.
RESULTS
A total of 438 5-FU samples and 578 oxaliplatin samples were analysed in plasma and peritoneal fluid. Bevacizumab was quantified with 17 measurements in plasma and 15 measurements IP. Median IP/IV ratios were 0.143, 0.352 and 0.085 for 5-FU, oxaliplatin and bevacizumab, respectively. Oxaliplatin exhibited a longer IP half-life than 5-FU. A correlation was found between oxaliplatin and bevacizumab IP/IV ratios (R=0.69, p=0.01). No statistical correlations were found between the other investigated drugs.
CONCLUSIONS
Our findings indicate that only a small percentage of systemically administered anti-cancer treatment reaches the IP cavity, questioning their efficacy against PM. This strengthens the hypothesis for repeated intraperitoneal chemotherapy to reach adequate anti-cancer drug levels.

BACKGROUND
Perforating foreign bodies from the gastrointestinal tract, such as wooden skewers, are reported in the small animal literature producing inflammatory/infectious lesions in the thorax, abdomen, and musculoskeletal system, which can be life-threatening in some instances. Several imaging modalities have been used, and advanced imaging techniques have shown a great advantage in its diagnosis and pre-surgical planning.
AIM
The objective of this study is to describe the computed tomographic findings in a group of seven medium to large breed dogs with perforating wooden skewers and foreign bodies migrated from the gastrointestinal tract.
METHODS
The medical records database was searched for dogs with a suspected diagnosis of a perforating wooden foreign body migrated from the gastrointestinal tract in which a computed tomographic study was performed. Signalment, history, and clinicopathological findings (when available) were retrieved, and the computed tomographic studies were reviewed.
RESULTS
Clinical signs vary depending on the anatomical regions affected through the perforating pathway. All foreign bodies were identified and showed a median attenuation of 79 HU, with the most common localization being the stomach followed by the jejunum. Peritoneal fat stranding surrounding the perforation site was the most frequent computed tomographic finding. The presence of peritoneal free fluid and/or gas was uncommon. Pleural effusion, pulmonary perforation, and pneumothorax were present in most of the cases with the foreign body traversing the pleural space. Pulmonary cavitary lesions were always reported when the ending tip of the wooden skewer was within the pulmonary parenchyma. Soft tissue abscessation was recognized in all cases where the ending tip was lodged in muscular or subcutaneous tissues.
CONCLUSION
Findings supported the variability of the secondary lesions caused by this type of foreign body and the utility of computed tomography in their recognition, as well as in the identification of the wooden skewer.
