[show abstract][hide abstract] ABSTRACT: We report a 49-year-old right lobe liver transplant recipient, who developed a significant anastomotic stenosis of the right hepatic vein shortly thereafter. Shear wave elastography (SWE) was applied to investigate liver stiffness quantitatively. It showed increased stiffness in the anterior compared with the posterior segment of right lobe graft. The stenotic right hepatic venous anastomosis was then managed by angioplasty with stent placement. SWE after angioplasty showed a gradual decrease in stiffness of the anterior segment, which was almost equal to the posterior segment at 2 weeks thereafter. Our experience suggested that SWE may be a noninvasive tool to assess alterations in liver stiffness secondary to hepatic venous congestion after liver transplantation.
[show abstract][hide abstract] ABSTRACT: The objective of this study was to explore the donor and recipient factors related to the spectral Doppler parameters of the transplant kidney in the early posttransplantation period.
This retrospective study included 76 patients who underwent renal transplantation assessed using Doppler ultrasonography (US) on the first postoperative day. We compared spectral Doppler parameters (peak systolic velocity [PSV] and resistive index [RI]) of the segmental artery of the transplant kidney according to the type of renal transplant, level of serum creatinine (SCr) of donor prior to organ donation, and donor/recipient age.
RI was significantly higher in deceased-donor kidney transplantation (DDKT) as compared with living-donor kidney transplantation (LDKT; 0.73 ± 0.10 vs 0.66 ± 0.11; P = .007). In the DDKT recipients, multivariate analysis showed donor SCr was the only factor affecting PSV (P = .023), whereas recipient age was the only factor affecting RI (P = .035). In the LDKT recipients, multivariate analysis showed recipient age was the only factor affecting both PSV (P = .009) and RI (P = .018).
Spectral Doppler parameters in the early posttransplantation period are related to the type of renal transplant, donor renal function, and recipient age. These factors should be taken into consideration when interpreting the results of spectral Doppler US.
[show abstract][hide abstract] ABSTRACT: Erlotinib, a kind of epidermal growth factor receptor tyrosine kinase inhibitor, is a target therapy and approved for the treatment of metastatic non-small cell lung cancer (NSCLC) and advanced pancreatic cancer. Among these EGFR-TKI agents, including gefitinib and erlotinib, the common dose-limiting toxicities are diarrhea, mucositis and skin rash (Acneform eruptions). In addition to the above adverse effects, infrequent but potentially fatal and lethal entity complications include acute interstitial lung disease (ILD) and acute hepatitis. The incidence of EGFR-TKI agents (gefitinib and erlotinib) induced acute hepatitis is rare and hepatotoxicity of EGFR-TKI agent was rarely discussed. The treatment of EGFR-TKI agents induced acute hepatitis remains uncertain and cessation medication is current policy. Here we reported a case of erlotinib induced interstitial pneumonitis and acute hepatitis with clinical appearance of hypoxemia and general weakness, treated with high dose pulse therapy and showed good recovery.

[show abstract][hide abstract] ABSTRACT: Neuroendocrine tumors (NETs) occur in the bronchopulmonary system. Extrapulmonary NETs are rare and are considered to ac count for 2.5 - 5% of all NETs, with more than 60% of these tumors occurring along the gastro intestinal tract, including primary NET of the gall bladder. Pri mary NETs of the gall bladder have been classified as carcinoid, neuroendocrine carcinoma or heterogeneous carcinoma. Currently, the main treatment of neuroendocrine car ci noma re mains surgery. The role of radiotherapy and chemotherapy is undefined be cause of the paucity of data. In advanced cases, chemotherapy has been prescribed with such effective agents as cisplatin, carboplatin, etoposide and paclitaxel. Here we re port a case of a 64-year-old Taiwanese male patient with neuroendocrine carcinoma of the gall bladder who received combined chemoradiotherapy (CCRT) with cisplatin, 5- fluorouracil and leucovorin (PFL) from June 2009 un til now, and whose disease is stable. CCRT with PFL may be a possible reg i men for high-grade neuroendocrine carcinoma of the gall bladder.

[show abstract][hide abstract] ABSTRACT: We report a case of acute interstitial pneumonitis and respiratory failure occurring in a 69-year-old, previously healthy patient receiving FOLFOX regimen plus cetuximab for colon cancer. Association between this chemotherapy regimen and interstitial pneumonitis is rarely reported in the literature. We treated the patient with pulse steroid therapy, and improvement in respiratory function and decreased pulmonary infiltrations demonstrated good response to steroids use. However, the patient ultimately expired from respiratory complications after 98 days from admission, possibly due to secondary infection. Both oxaliplatin and cetuximab have rarely been associated with interstitial pneumonitis, and our case may serve as an important reference for physicians notice in patients receiving these chemotherapeutic agents.
