Successful Treatment of Severe Case of Lipid Overload Syndrome with Pancreatitis and Pneumonia: A Case Report.

Background: Fat overload syndrome is a rare and severe adverse reaction triggered by the infusion of a single source of lipid emulsion, resulting in elevated blood triacylglycerol (TG) levels. The majority of literature reports focus on cases of fat overload syndrome in patients with mild symptoms. This case is significant because it demonstrates the diagnostic and therapeutic experience and provide valuable insights for the management for severe fat overload syndrome. Case Presentation: We present a case report of a female patient who developed fat overload syndrome following prolonged and excessive infusion of lipid emulsion after colon resection surgery. In the setting of compromised immune function and malnutrition, the patient's pulmonary infection and respiratory distress symptoms have further exacerbated. Hence, in addition to severe pancreatitis, the patient has also contracted severe pneumonia. Upon admission, tracheal intubation, plasma exchange and blood perfusion were performed. Subsequently, comprehensive treatment was provided, including anti-infection, antispasmodic, acid suppression, enzyme inhibition, as well as targeted supportive measures to stabilize electrolytes and nutritional status. After treatment, there was a progressive reduction in blood lipid levels. After assessing the relevant risks, it was deemed necessary to perform an emergency computed tomography (CT)-guided percutaneous drainage tube placement procedure targeting the necrotic area of the pancreas while the patient was still intubated. Finally, the patient was discharged from the hospital. Conclusion: The case highlights the association between fat overload syndrome and pancreatitis as well as the use of lipid emulsions and suggests the treatment strategies for severe fat overload syndrome.

Acute transient swelling of the thyroid following fine-needle aspiration: A case series.

Acute transient swelling (ATS) of the thyroid is a rare complication following fine-needle aspiration (FNA) of thyroid nodules. We present 31 cases with 35 nodules encountered at our institute and reported in the literature, to provide further information. The incidence rate in our institute was 0.46%. Of these nodules, 74.3% (26/35) were solid, 65.7% (23/35) exhibited hypervascularity, and 77.2% (27/35) were benign or follicular neoplasms. Although most cases (87.1%, 27/31) occurred within 2 h after FNA, four patients experienced delayed ATS after 7 h to 2 days. Therefore, awareness of this complication, especially its delayed occurrence, should be raised.

Optimizing the Use of the Gamma-Glutamyl Transpeptidase-to-Platelet Ratio and Transient Elastography to Identify Liver Cirrhosis in Patients with Chronic Hepatitis B Concurrent with Nonalcoholic Fatty Liver Disease.

BACKGROUND AND AIM: Little information is available about the assessment and optimal use of the gamma-glutamyl transpeptidase-to-platelet ratio (GPR) and transient elastography (TE) in predicting liver cirrhosis in patients with chronic hepatitis B (CHB) and concurrent nonalcoholic fatty liver disease (NAFLD). This study is aimed at comparing their diagnostic performances and developing an optimal approach for predicting liver cirrhosis in CHB patients with NAFLD. METHODS: Consecutive CHB patients with NAFLD were enrolled. The GPR was calculated, and TE was performed using liver biopsy as a reference standard. The accuracy of predicting liver cirrhosis using GPR and TE was assessed and compared, and an optimal approach was developed. RESULTS: Both TE and GPR correlated significantly with the histological fibrosis stage. TE and GPR had excellent performance in predicting liver cirrhosis, and the comparison of areas under the receiver operating characteristic curves revealed that TE was superior to GPR (0.95 vs. 0.85, P = 0.039). Moreover, the dual cutoffs established by the likelihood ratio showed that GPR had a similar misclassification but higher indeterminate rate than TE (54.5% vs. 11.7%, P < 0.001). Additionally, a 2-step approach using GPR followed by TE had comparable performance to that of both GPR and TE tests for all patients (misclassification: 8.9% vs. 8.3%, P = 0.866; indeterminate rate: 15.2% vs. 17.2%, P = 0.750) but could reduce TE scans by approximately one-third. CONCLUSIONS: Both TE and GPR show excellent performance in predicting liver cirrhosis in CHB patients with NAFLD. The 2-step approach using GPR followed by TE may be optimal for the assessment of cirrhosis in CHB patients with NAFLD.

Crystal structure of taxodione isolated from Taxodium ascendens (B.).

The title compound [systematic name: (4bS)-4-hy-droxy-2-isopropyl-4b,8,8-trimethyl-4b,5,6,7,8,8a-hexa-hydro-phenanthrene-3,9-dione], C20H26O3, is an abietane-type diterpene, which was isolated from Taxodium ascendens (B.). In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, forming supra-molecular chains propagating along the [001] direction.

¹8F-fluorodeoxyglucose PET/CT findings of a solitary primary hepatic lymphoma: a case report.

Primary hepatic lymphoma is extremely rare, and only a few cases have been described on positron emission tomography (PET) or PET/computed tomography (PET/CT) imaging in the English literature. We report a case of a 55-year-old woman who presented with low-grade fever and weight loss of three months. On CT scanning, a mass was identified which appeared to be a hypoattenuating lesion, on ultrasonographic imaging, the mass was hypoechoic, therefore, liver abscess or hepatic metastasis from a gastrointestinal primary was initially suspected. Tumor markers such as alpha-fetoprotein, carcinoembryonic antigen and carbohydrate antigen 19-9 were within normal limits. PET/CT demonstrated a large abnormal ring-like hypermetabolic focus in the right liver lobe. The lesion was resected and the histopathological findings were consistent with lymphoma. The patient was discharged two weeks after surgery and did not receive any further treatment. After 25 mo follow-up, she is in good health. (18)F-fluorodeoxyglucose PET/CT is useful in confirming the diagnosis of primary hepatic lymphoma by demonstrating no other foci with high uptake in other parts of the body.

WITHDRAWN: Transplantation of bone mesenchymal stem cells containing the nerve growth factor gene in adult rat brain with Fimbria Fornix lesion.

Bone marrow-derived mesenchymal stem cells (BMSCs) are a promising source for cell-based treatment of brain injury, but the therapy of BMSCs is restricted by low cell survival. We examined whether nerve growth factor (NGF) improve BMSCs viability in the brain with Fimbria-Fornix lesion (FF). After transduction of NGF gene via recombinant retroviral vectors, the rat BMSCs were transformed into the NGF-GFP positive BMSCs, nearly 100% of cells expressed NGF. After transplanted into basal forebrain of rat with FF, the NGF-GFP positive BMSCs expressed the exogenous NGF gene in the host brain, and interesting, the survival number of BMSCs in the NGF group was significant more than that of the void plasmid group. Furthermore, the number of choline acetyltransferase (ChAT) immunoreactive neurons of NGF group was also significant higher than those of the void plasmid group (p<0.05) or the PBS group (p<0.01). Performance in the water maze test was improved in these rats in NGF group. These results indicate that NGF increased BMSCs survival in brain with FF, which results in better improvement of brain function than injected with BMSCs alone.
