Fulltext Chylous leakage post mastectomy and axillary clearance: clinical aspect, causes and review of literature

Chan AC, Sarojah A

Med J Malaysia, 2013 Jun;68(3):262-3.

Chylous leakage after mastectomy & axillary clearance is a rare complication. The incidence is less than 0.5%. Anatomical variations in the termination of thoracic duct can occur, rendering it susceptible to injury during axillary dissection. Most chyle leaks in the axilla are managed through conservative measures. Surgical intervention is required in high output chylous leaks. We encountered a case of chylous leak post mastectomy with axillary clearance, which was successfully treated conservatively.

Emphysematous pyelonephritis is a rare but life threatening infection of kidney that is characterized by gas formation within or around the kidney. We describe a case of emphysematous pyelonephritis as a consequence of inadequately treated pelvic-ureteric stone in a diabetic man and complement this with a brief review of the literature pertaining in particular to the management of this condition.

Acupunct Med, 2021 02;39(1):64-68.

PMID: 32539426 DOI: 10.1177/0964528420920307

INTRODUCTION: The objective of this retrospective study was to evaluate the effectiveness and safety of acupuncture-assisted anesthesia (AAA) in breast lump excision.

METHODS: The medical records of all patients who underwent breast lump excision under AAA in combination with electrical stimulation at traditional acupuncture points in 2016 were examined. All of them (n = 17) received electrostimulation (2-4 Hz) using single needles inserted at bilateral LI4 and PC6. They also underwent insertion of four acupuncture needles at the lump site, which were electrically stimulated at 30 Hz frequency.

RESULTS: All surgical procedures were successful with minimal use of analgesics and local anesthetic. The median pain score reported was 1/10 (interquartile range (IQR) = 2/10) at the first hour, and slightly increased to 2/10 (IQR = 2/10) between 24 and 48 h of the surgery. No major postoperative adverse events were documented, except for drowsiness in one case.

CONCLUSION: AAA was found to be generally safe and effective for anaesthesia and analgesia in breast lump excision. However, a large-scale randomized controlled study is required to verify the findings.

Fulltext Efficacy of radiofrequency ablation compared with transarterial chemoembolization for the treatment of recurrent hepatocellular carcinoma: a comparative survival analysis

Koh PS, Chan AC, Cheung TT, Chok KS, Dai WC, Poon RT, et al.

PMID: 26776854 DOI: 10.1016/j.hpb.2015.07.005

This study aims to assess if radiofrequency ablation (RFA) has any oncological superiority over transarterial chemoembolization (TACE) on post-hepatectomy recurrence.

Efficacy of radiofrequency ablation compared with transarterial chemoembolization for the treatment of recurrent hepatocellular carcinoma: a comparative survival analysis

BACKGROUND: This study aims to assess if radiofrequency ablation (RFA) has any oncological superiority over transarterial chemoembolization(TACE) on post-hepatectomy recurrence.

METHODS: From 2002 to 2011, 60.15% of 823 patients developed recurrence after hepatectomy for HCC. One hundred and two patients with recurrence underwent RFA (n = 42) or TACE (n = 60) for tumour size ≤5 cm and number of lesions ≤ 3 when tumours were not resectable or transplantable. Those with renal impairment, portal vein thrombosis and poor liver reserve were excluded. The primary outcome was overall survival, which was determined using log-rank test and Kaplan-Meier plots performed. Categorical data were analysed using the chi-square test and continuous variable were analysed using the Mann-Whitney U-test.

RESULTS: Demographics and primary tumour characteristics were similar in both groups (P > 0.05). Overall survival (OS) after an initial hepatectomy and salvage treatment for recurrence was similar (P > 0.05) in both groups with a 5-year OS after salvage treatment for RFA and TACE at 24.1% and 25.7%, respectively. For patients with the second recurrence after salvage treatment, an interchangeable treatment strategy of RFA and TACE conferred a better survival outcome than a stand-alone treatment with RFA or TACE (P < 0.05).

CONCLUSIONS: RFA and TACE may be equally effective for intrahepatic recurrence after hepatectomy when the tumour size is ≤ 5 cm and ≤ 3 lesions when re-resection or salvage transplantation is not considered feasible.

Acute-on-chronic liver failure: consensus recommendations of the Asian Pacific Association for the Study of the Liver (APASL) 2014

The first consensus report of the working party of the Asian Pacific Association for the Study of the Liver (APASL) set up in 2004 on acute-on-chronic liver failure (ACLF) was published in 2009. Due to the rapid advancements in the knowledge and available information, a consortium of members from countries across Asia Pacific, "APASL ACLF Research Consortium (AARC)," was formed in 2012. A large cohort of retrospective and prospective data of ACLF patients was collated and followed up in this data base. The current ACLF definition was reassessed based on the new AARC data base. These initiatives were concluded on a 2-day meeting in February 2014 at New Delhi and led to the development of the final AARC consensus. Only those statements which were based on the evidence and were unanimously recommended were accepted. These statements were circulated again to all the experts and subsequently presented at the annual conference of the APASL at Brisbane, on March 14, 2014. The suggestions from the delegates were analyzed by the expert panel, and the modifications in the consensus were made. The final consensus and guidelines document was prepared. After detailed deliberations and data analysis, the original proposed definition was found to withstand the test of time and identify a homogenous group of patients presenting with liver failure. Based on the AARC data, liver failure grading, and its impact on the "Golden therapeutic Window," extra-hepatic organ failure and development of sepsis were analyzed. New management options including the algorithms for the management of coagulation disorders, renal replacement therapy, sepsis, variceal bleed, antivirals, and criteria for liver transplantation for ACLF patients were proposed. The final consensus statements along with the relevant background information are presented here.
