Introduction: Necrotizing pancreatitis management is complex and varies significantly among clinicians. Minimally invasive approaches like transgastric necrosectomy via laparoscopy are emerging as effective treatment options. This case report underscores the technique’s efficacy, clinical outcomes, and role in reducing complications. Clinical Observation: A 59-year-old male with a history of smoking and alcoholism presented with severe abdominal pain, nausea, and vomiting. Over the following weeks, he developed symptoms including asthenia, weight loss, and melena. Diagnostic workup revealed severe anemia and Balthazar E necrotizing pancreatitis, with significant intra-abdominal fluid collections and signs of infection. After initial conservative management, the patient underwent transgastric necrosectomy via laparoscopy due to deteriorating clinical status. The procedure involved removing necrotic tissue and performing a cystogastroanastomosis and jejunostomy. Postoperative care included fasting, parenteral nutrition, broad-spectrum antibiotics, and enzymatic replacement. The patient recovered well, with reduced necrotic tissue on follow-up imaging, and was discharged twelve days post-surgery [1]. Conclusion: Transgastric necrosectomy by laparoscopy is a valuable first-line surgical option for patients with symptomatic necrotizing pancreatitis, particularly in cases without prior interventions. This minimally invasive technique helps reduce major complications and mortality, offering a less invasive alternative to traditional open necrosectomy. The multidisciplinary approach and careful postoperative management were crucial to the patient’s favorable outcome. The case highlights the potential of transgastric necrosectomy as an effective treatment strategy in managing complex pancreatitis cases, including those with associated duodenal perforation [2].

Background : The objective of this study was to validate an animal model for dry eye during and after the administration of 1% ophthalmic atropine sulfate(OAS) in New Zealand white(NZW) *** : OAS(1%) was applied three times per day to 30 eyes of 15 healthy NZW rabbits. Sacrifice, enucleation, and lacrimal gland removal took place on days 15, 21,and 30(OAS group). A second group(n = 5) was used as control. Clinical evaluations took place on days 3, 10, 15, 18, 21, 24 and 30. The primary endpoints were:Schirmer I test, tear break-up time(TBUT), and corneal fluorescein staining. As secondary endpoints, clinical changes including intraocular pressure, and histopathology were *** : While OAS was administered, the Schirmer I test showed a statistically significant reduction for OAS group versus control( p < 0.001), and versus basal production( p < 0.001). TBUT showed statistically significant differences between groups(days 3 and 10;p = 0.001) and versus basal values(day 3;p < 0.001). Fluorescein staining showed a statistically significant difference(day 3;p = 0.001). The most frequent clinical finding was conjunctival hyperemia(76.9% OAS vs. 20% control). For histopathology, all OAS subjects presented some degree of inflammation(86.7% minimal;13.3% mild) whereas the control presented only 30% minimal inflammation. Goblet cell density showed no *** : The effectiveness of the OAS dry eye model in NZW rabbits as reported in previous studies was confirmed, provided that the application of the drug is maintained throughout the intervention;it is not a viable model after OAS administration is suspended.

Objective To evaluate immediate transcatheter aortic valve implantation （TAVI） results and medium-term follow-up in very elderly pa- tients with severe and symptomatic aortic stenosis （AS）. Methods This multicenter, observational and prospective study was carried out in three hospitals. We included consecutive very elderly （〉 85 years） patients with severe AS treated by TAVI. The primary endpoint was to evaluate death rotes from any cause at two years. Results The study included 160 consecutive patients with a mean age of 87 ± 2.1 years （range from 85 to 94 years） and a mean logistic EuroSCORE of 18.8% ± 11.2% with 57 （35.6%） patients scoring 〉 20%. Procedural success rate was 97.5%, with 25 （15.6%） patients experiencing acute complications with major bleeding （the most frequent）. Global mortality rate during hospitalization was 8.8% （n = 14） and 30-day mortality rate was 10% （n = 16）. Median follow up period was 252.24± 232.17 days. During the follow-up period, 28 （17.5%） patients died （17 of them due to cardiac causes）. The estimated two year overall and cardiac survival rates using the Kaplan-Meier method were 71% and 86.4%, respectively. Cox proportional hazard regression showed that the variable EuroSCORE ≥ 20 was the unique vari- able associated with overall mortality. Conclusions TAVI is safe and effective in a selected population of very elderly patients. Our findings support the adoption of this new procedure in this complex group of patients.

Occult hepatitis B virus co-infection in human immunodeficiency virus-positive patients: A review of prevalence, diagnosis and clinical significance

引用

World Journal of Hepatology 2015年第2期7卷 253-260页

作者： Angelica Maldonado-Rodriguez Ana Maria Cevallos Othon Rojas-Montes Karina Enriquez-navarro Ma Teresa Alvarez-Mu?oz Rosalia Lira Unidad de Investigacion Medica en Enfermedades Infecciosas y Parasitarias Hospital de Pediatria Centro Medico Nacional Siglo XXI Instituto Mexicano del Seguro Social Departamento de Biologia Molecular y Biotecnologia Instituto de Investigaciones Biomedicas Universidad Nacional Autonoma de Mexico

The prevalence of human immunodeficiency virus(HIV) and hepatitis B virus(HBV) co-infection is high as they share similar mechanisms of transmission. The development and widespread use of highly sensitive tests for HBV diagnosis has demonstrated that a significant proportion of apparently healthy individuals with evidence of exposure to HBV continue to carry fully functional HBV DNA in their hepatocytes, a situation that predisposes them to the development of progressive liver disease and hepatocellular carcinoma. The presence of co-infections frequently influences the natural evolution of each of the participating infections present by either facilitating their virulence or competing for resources. Furthermore, the drugs used to treat these infections may also contribute to changes in the natural course of these infections, making the analysis of the impact of co-infection more difficult. The majority of studies has examined the impact of HIV on overt chronic hepatitis B, finding that co-infection carries an increased risk of progressive liver disease and the development of hepatocellular carcinoma. Although the effect of HIV on the natural history of occult hepatitis B infection(OBI) has not been fully assessed, all available data suggest a persisting risk of repeated flares of hepatitis and progressive liver disease. We describe studies regarding the diagnosis, prevalence and clinical significance of OBI in HIVpositive patients in this short review. Discrepancies in worldwide prevalence show the urgent need for the standardization of diagnostic criteria, as established by the Taormina statements. Ideally, standardized protocols for testing should be employed to enable the comparison of data from different groups. Additional studies are needed to define the differences in risk for OBI without HIV and in HIV-HBV co-infected patients with or without overt disease.
