Eikenella corrodens isolated from pleural effusion:A case report

BACKGROUND The bacterium Eikenella,classified as a gram-negative member of the phylum Proteobacteria,is distinguished by its rarity,corrosive nature,facultative anaerobic properties,and conditional pathogenicity.It represents the sole species within its genus-Eikenella corrodens(E.corrodens)-and can be found colonizing both human and animal oral and nasopharyngeal regions.Additionally,it occasionally inhabits the gastrointestinal or urogenital tracts.However,its slow growth rate can be attributed to its high nutritional requirements.However,there is an uneven distribution of construction and diagnostic capacity in China which poses undeniable challenges for the clinical examination and analysis of this case,especially in the basic hospitals.CASE SUMMARY Here we presented a case of empyema associated with E.corrodens infection in a 67-year-old male patient without any previous history of infectious diseases in our primary hospital in Dongguan district of China.The patient was admitted due to recurrent worsening cough,sputum production,and dyspnea for 3 d,which had persisted for over 20 years.Moreover,the patient experienced a onehour episode of unconsciousness.Upon admission,immediate comprehensive examinations were conducted on the patient which subsequently led to his admission to the intensive care unit.Meanwhile,the patient presented with drowsiness and profuse sweating along with bilateral conjunctival edema observed during initiation of non-invasive ventilation,suggesting empyema.A significant amount of coffee-colored malodorous pleural fluid was drained during the procedure above and sent to the laboratory department for inspection.Finally,laboratory culture results confirmed the presence of E.corrodens infection in the pleural fluid sample.The patient received antimicrobial therapy until died on day 22 in the hospital.CONCLUSION In this report,we presented a case of empyema associated with E.corrodens infection.Multiple courses of morphological examination,viable culture analysis,and biochemical identification revealed its difficulties in detecting distinctive characteristics,as well as a detection model worth promoting.It’s just that there were still certain deficiencies in terms of morphological assessment,biochemical identification,and drug susceptibility testing.

Successful totally laparoscopic right trihepatectomy following conversion therapy for hepatocellular carcinoma:A case report

BACKGROUND About 20%-30%of newly diagnosed hepatocellular carcinoma(HCC)patients are surgically feasible due to a variety of reasons.Active conversion therapy may provide opportunities of surgery for these patients.Nevertheless,the choice of surgical procedure is controversial after successful conversion therapy.We report a patient with HCC who underwent successful laparoscopic right trisectionectomy after conversion therapy with portal vein embolization and transarterial chemoembolization.CASE SUMMARY A 67-year-old male patient presented to our hospital with epigastric distention/discomfort and nausea/vomiting for more than 1 mo.Contrast-enhanced computed tomography scan of the abdomen demonstrated multiple tumors(the largest was≥10 cm in diameter)located in the right liver and left medial lobe,and the left lateral lobe was normal.The future remnant liver(FRL)of the left lateral lobe accounted for only 18%of total liver volume after virtual resection on the three-dimensional liver model.Conversion therapy was adopted after orally administered entecavir for antiviral treatment.First,the right portal vein was embolized.Then tumor embolization was performed via the variant hepatic arteries.After 3 wk,the FRL of the left lateral lobe accounted for nearly 30%of the total liver volume.Totally laparoscopic right trisectionectomy was performed under combined epidural and general anesthesia.The in situ resection was performed via an anterior approach.The operating time was 240 min.No clamping was required during the surgery,and the intraoperative blood loss was 300 mL.There were no postoperative complications such as bile leakage,and the incision healed well.The patient was discharged on the 8th postoperative day.During the 3-mo follow-up,there was no recurrence and obvious hyperplasia of residual liver was observed.Alpha-fetoprotein decreased significantly and tended to be normal.CONCLUSION Due to the different biological characteristics of the liver cancer and the pathophysiological features of the liver from other organs,the conversion treatment should take into account both the feasibility of tumor downstaging and the volume and function of the remnant liver.Our case provides a reference for clinicians in terms of both conversion therapy and laparoscopic right trisectionectomy.

Successful treatment of refractory gastric antral vascular ectasia by distal gastrectomy:A case report

Gastric antral vascular ectasia (GAVE) is an uncommon and often neglected cause of gastric hemorrhage. The treatments for GAVE include surgery, endoscopy and medical therapies. Here, we report an unusual case of GAVE. A 72-year-old man with a three-month history of recurrent melena was diagnosed with GAVE. Endoscopy revealed the classical “watermelon stomach” appearance of GAVE and complete pyloric involvement. Melena reoccurred three days after argon plasma coagulation treatment, and the level of hemoglobin dropped to 47 g/L. The patient was then successfully treated with distal gastrectomy with Billroth II anastomosis. We propose that surgery should be considered as an effective option for GAVE patients with extensive and severe lesions upon deterioration of general conditions and hemodynamic instability.
