  • Surgical Indications and Techniques for Adrenalectomy Review
    THE MEDICAL BULLETIN OF SISLI ETFAL HOSPITAL DOI: 10.14744/SEMB.2019.05578 Med Bull Sisli Etfal Hosp 2020;54(1):8–22 Review Surgical Indications and Techniques for Adrenalectomy Mehmet Uludağ,1 Nurcihan Aygün,1 Adnan İşgör2 1Department of General Surgery, Sisli Hamidiye Etfal Training and Research Hospital, Istanbul, Turkey 2Department of General Surgery, Bahcesehir University Faculty of Medicine, Istanbul, Turkey Abstract Indications for adrenalectomy are malignancy suspicion or malignant tumors, non-functional tumors with the risk of malignancy and functional adrenal tumors. Regardless of the size of functional tumors, they have surgical indications. The hormone-secreting adrenal tumors in which adrenalectomy is indicated are as follows: Cushing’s syndrome, arises from hypersecretion of glucocorticoids produced in fasciculata adrenal cortex, Conn’s syndrome, arises from an hypersecretion of aldosterone produced by glomerulosa adrenal cortex, and Pheochromocytomas that arise from adrenal medulla and produce catecholamines. Sometimes, bilateral adre- nalectomy may be required in Cushing's disease due to pituitary or ectopic ACTH secretion. Adenomas arise from the reticularis layer of the adrenal cortex, which rarely releases too much adrenal androgen and estrogen, may also develop and have an indication for adrenalectomy. Adrenal surgery can be performed by laparoscopic or open technique. Today, laparoscopic adrenalectomy is the gold standard treatment in selected patients. Laparoscopic adrenalectomy can be performed transperitoneally or retroperitoneoscopi- cally. Both approaches have their advantages and disadvantages. In the selection of the surgery type, the experience and habits of the surgeon are also important, along with the patient’s characteristics. The most common type of surgery performed in the world is laparoscopic transabdominal lateral adrenalectomy, which most surgeons are more familiar with.

Summary A 24-year old previously healthy woman presented with a six-month history of weight gain, amenorrhea, hirsutism, acne, and hypertension. Biochemical evaluation revealed hypercortisolism and elevated DHEA-S. Abdominal imaging demonstrated an 11 cm right adrenal mass, abutting the right hepatic lobe, right kidney, and inferior vena cava. The patient underwent open right adrenalectomy for the presumptive diagnosis of hormonally active adrenocortical carcinoma (ACC). The tumor was able to be mobilized from surrounding structures without requiring resection of adjacent organs. Pathological exam demonstrated a 728 g, 16.5 cm ACC with extensive necrosis, and Ki67 proliferation index of 35% and large vessel vascular invasion. Postoperatively, the symptoms of hypercortisolism, virilization, and hypertension resolved. The patient is currently undergoing adjuvant mitotane therapy and has no evidence of disease six months after surgery.

  • Thyroidectomy –
    Thyroidectomy – an operation to remove all or part of the thyroid gland Information for patients page 2 What is the thyroid gland? The thyroid gland is an endocrine gland which makes hormones that are released into the bloodstream. These hormones affect cells and tissues in other parts of the body and help them to function normally. The thyroid is made up of two lobes, each about half the size of a plum. The two lobes lie on either side of your windpipe, with the gland as a whole lying just below your Adam’s apple. The thyroid gland produces three hormones, that are released into the bloodstream: • thyroxine, often called T4 • triiodothyronine, often called T3. In the body, T4 is converted into T3 and this is what influences the way cells and tissues work. • calcitonin – this is involved in controlling calcium levels in the blood. With medullary thyroid cancer (MTC), too much calcitonin is produced, however this does not lead to any significant change in calcium levels. Thyroxine and T3 can both be replaced by medication and the body can function perfectly well with little or no calcitonin. Thyroid hormones T3 and T4 help to control the speed of body processes – otherwise known as your metabolic rate. If too much of these thyroid hormones is released, your body starts to work faster than normal and you develop ‘hyperthyroidism’. This would make you feel overactive and anxious, hungrier than usual, and you would lose weight. However, if too little of these thyroid hormones is produced, your body will start to work slower than normal and you develop ‘hypothyroidism’.

Early detection is difficult and prognosis is poor. We report on 20 years of ACC surgical experience at our institution. Methods: This study included 32 ACC patients who underwent surgical resection at the Department of Surgery of the Yonsei University Health System in South Korea between January 1990 and February 2012. We reviewed these 32 patients and retrospectively analyzed long-term clinical outcomes and prognosis after radical surgery for ACC. Results: The median age of the 32 patients at diagnosis was 42.25 years (range 3∼81 years). There were 16 (50%) female and 16 (50%) male patients. Mean tumor size was 12.36 cm (range 1.8∼20 cm). Twenty-five patients (78.12%) had nonfunctioning tumors while the other seven patients (21.87%) had functioning tumors. Seventeen patients (53.12%) were classified as stage II, two (6.25%) as stage III, and 13 (40.62%) as stage IV. Fourteen patients underwent radical surgical resection, while 14 patients received adjuvant chemotherapy, two received adjuvant radiotherapy, and two received adjuvant chemora- diation.

  • Indigenous AFL Players
    'Magicians', 'freaks' and 'marvels': how the media 'Others' Indigenous AFL players. Assessment Item 3: Research Project Tom Smith 10877177 Question How does the media 'Other' Indigenous AFL players? Abstract Although overt racism has been virtually eradicated from the AFL, the media's depiction of Indigenous players covertly reinforces negative racial stereotypes. A content analysis of the round eight game between Hawthorn and Fremantle on May 19 2012 reveals a demonstrable difference in the way Aboriginal and non-Aboriginal footballers are portrayed by television, radio and newspaper commentators. This match is typical of the broader regime of representation of Indigenous players, which emphasises natural ability, physical superiority, instinct and 'magic' rather than mental discipline or cognitive skills. These imagined values simultaneously idolise the Aboriginal body and infantilise the Aboriginal mind, with the overall effect of 'spectacularising' the Aboriginal AFL player. With several Indigenous identities recently criticising this 'common sense' stereotype, this article investigates how existing representational practices 'Other' Indigenous AFL players and entrench the dominant racial hegemony. Key terms AFL, Indigenous Australia, media, stereotypes, racism. Introduction Since the likes of Graham 'Polly' Farmer, Barry Cable and Maurice Rioli blazed the trail for Indigenous involvement in the Victorian Football League - now the Australian Football League (AFL) - in the 1960s and '70s, the relationship between Aboriginal players
