  1. Fulltext Aorto-oesophageal fistula and aortic pseudoaneurysm caused by a swallowed fish bone
    Sia KJ, Ashok GD, Ahmad FM, Kong CK
    Hong Kong Med J, 2013 Dec;19(6):542-4.
    PMID: 24310662 DOI: 10.12809/hkmj133668
    We describe a rare case of aorto-oesophageal fistula and aortic pseudoaneurysm in a middle-aged man, who presented with chest pain and haematemesis 1 week after swallowing a fish bone. Oesophagogastroduodenoscopy and computed tomographic angiography findings were consistent with oesophageal perforation, proximal descending aortic pseudoaneurysm, and aorto-oesophageal fistula. Thoracic endovascular aortic repair was performed. The patient died from severe mediastinal sepsis. Early surgical intervention and broad-spectrum antibiotic therapy are crucial in preventing life-threatening mediastinal infection.

    BACKGROUND: Each year 1.5 million women experience menopause when menstrual cycles cease resulting from the loss of ovarian function and oestrogen deprivation, a hormone that helps prevent bone loss. This study investigated the effects of Physta®, a standardized herbal extract of Eurycoma longifolia Jack (PEL), on hormonal balance and parameters associated with hormonal imbalance, namely body and uterus weight and bone biochemical markers relevant in menopausal symptoms.

    METHODS: Forty-eight Sprague Dawley rats were randomly divided into six groups of eight rats each: (A) Sham operated; control (B) Untreated (ovariectomised (OVX) with vehicle), (C) PEL 100 (OVX + 100 mg/kg body weight (bw)), (D) PEL 300 (OVX + 300 mg/kg bw), (E) PEL 500 (OVX + 500 mg/kg bw) and (F) Positive control, testosterone undecanoate (TU) (OVX+ 10 mg/kg bw). Group A and B received daily oral administrations of the vehicle, Group C-E received daily oral administration of PEL and Group F received testosterone undecanoate intramuscularly weekly. At the end of 8 weeks, serum calcium, phosphate, bone alkaline phosphatase (BALP), osteocalcin, follicle stimulating hormone (FSH), luteinising hormone (LH), oestrogen, progesterone and testosterone were measured, then the animals were sacrificed and uterus was isolated, while weight was recorded in all experimental groups.

    RESULTS: Treatment of OVX rats with PEL at a dose of 500 mg/kg showed decreased serum FSH (P
