GP Information

Breast

Breast Screening:

  • 1 in 9 women in NSW will develop breast cancer in their lifetime and 9 out of 10 women who develop breast cancer do not have a family history of breast cancer.
  • The target (invited) age range for breast screening has been increased from 50-69 years to 50-74 years.
  • Women aged 40-49 years and over 75 years are eligible for free screening mammograms even though they are not Formally invited.
  • The proposed assessment clinic at Nepean Hospital will increase assess for the women who are found an abnormality in their screening mammogram

For further information: Breast Screen NSW http://www.bsnsw.org.au

Breast Symptoms:

Individuals at a high risk of Breast Cancer

Familial breast cancer:

Previous radiation therapy to the chest:

Those who had received radiotherapy to the chest for conditions like lymphoma at a young age are also at risk of developing breast cancer several decades after the treatment

  • If you have a patient at high risk of breast cancer and would like assistance please contact us or contact Dr. Edirimanne directly (mobile or email)

Post-operative care after breast cancer Surgery

Most breast cancer patients, especially those who had breast conserving surgery and sentinel node biopsy are discharged home on the same day or the next day morning. Dr. Edirimanne prefers Comfeel ®dressing which can be left in until the patients are seen at his rooms, which is 1-2 weeks after surgery.

Most patients who had mastectomy and/or axillary dissection are usually discharged home on post op day 1 or 2 with their drains in with community nurse care. Patients are also educated in drain care before discharge form the hospital. Unless otherwise specified these drains can be removed either by community nurses or GPs once drainage is about 30 mls/day on two consecutive days. Please make sure the decreased drainage is not due to a blocked drain.

Patients who had skin or nipple sparing mastectomy and immediate implant/expander reconstructions are usually discharged home after 3 days with drains in. The management of their drains is more complex and Dr. Edirimanne removes them himself at his rooms when appropriate. These patients remain on oral antibiotics until their drains are removed.

If you have any concern about a post-operative patient please contact us or Dr. Edirimanne directly (mobile or email)

Long term care of Breast Cancer patients

Long-term follow up care of breast cancer patients is a coordinated process involving breast surgeon, medical oncologist, radiation oncologist (sometimes) and the GP.

The frequency and duration of follow up by the breast surgeon is individualized to the patient. Generally, the patient is initially followed up 6 monthly and after 1-2 years, yearly for at least 5 years. Patients need yearly breast imaging that Dr. Edirimanne organizes. Patients are given advice regarding life style modifications to reduce recurrence, to maintain breast awareness by regular self-breast examinations.
If you or the patient is concerned about a new symptom or a treatment related problem please do not hesitate to contact us or Dr. Edirimanne directly (mobile or email)


 

Thyroid

Thyroid Nodules:

Thyroid nodules are common and about 7% of the population have palpable thyroid nodules and up to 50% of the population have nodules that can be demonstrated in an ultrasound. Even though the incidence of thyroid cancer is increasing (1 in 48 woman and 1 in 174 man in NSW will develop thyroid cancer by the age of 85) most thyroid nodules are not malignant.

Thyroid ultrasound, thyroid Function Tests and Fine Needle Aspiration are the essential initial investigations of a thyroid nodule. FNA is indicated for a thyroid nodule in the following situations.

High-risk history:

  • First-degree relative with thyroid cancer
  • External beam radiotherapy as a child
  • Ionizing radiation exposure as a child or adolescent
  • Previous thyroid cancer treated with hemi thyroidectomy

Suspicious features on ultrasound:

  • Punctate micro-calcifications
  • Intra-nodular vascularity
  • Infiltrative margins
  • Taller than wider on transverse view
  • Loss of halo
  • Abnormal cervical lymph nodes

Bethesda cytological classification is the current standard of reporting of thyroid cytology.

Radioisotope thyroid scan is only helpful if the patient is hyperthyroid.

The following patents with a thyroid nodule will benefit from a surgical consultation.

  • Bethesda category 3 or above on FNA cytology
  • Suspicious features on ultrasound
  • Benign nodules which are large, with continuing growth, pressure symptoms (dyspnoea, dysphagia, change in voice etc.) or causing disfigurement

Multi nodular goiter (MNG):

Prevalence of sporadic MNG is ~ 5%

Risk of cancer in a nodule in a MNG is the same as a solitary nodule. 3-16% MNG can have incidental thyroid cancer

The following patients with a MNG will benefit from a surgical consultation.

  • Suspicion for malignancy
  • Pressure symptoms (dyspnoea, dysphagia, change in voice etc.)
  • Retro-sternal extension
  • Hyperthyroidism (toxic MNG)
  • Disfigurement
  • Evidence of on going growth on-serial ultrasound examinations

Hyperthyroidism:

Common causes of hyperthyroidism include Graves’ disease, multi nodular goiter (Toxic) and solitary toxic thyroid nodule.

Radioisotope thyroid scan is helpful in differentiating these conditions.

The management of a hyperthyroid patient involves input from an endocrinologist. The following patients with hyperthyroidism will benefit from a surgical consultation as surgery is one of the definitive treatment options.

  • Solitary toxic thyroid nodule
  • Toxic MNG
  • Graves’ disease patients with suspicion for malignancy, large goiters with pressure symptoms, eye involvement, difficulty in control with medications, inability to tolerate medications or of younger age

If you have a patient with a thyroid condition and would like assistance please contact us or contact Dr. Edirimanne directly (mobile or email)

Post-operative care after thyroid surgery

Most Hemi/Partial thyroidectomy patients are discharged on post –op day 1 and Total thyroidectomy patients on post-op day 2. Dr. Edirimanne will see the patients 1-2 weeks after the surgery at his rooms. They have steri-strip® dressings and a Prolene® stitch that is to be removed about 5 days after the operation. Patients who had Total thyroidectomy are commenced on Thyroxine prior to their discharge with thyroid function tests done 4-6 weeks later. Temporary hypoparathyroidism is fairly common after total thyroidectomy and can last few days to several weeks after surgery. Dr. Edirimanne currently use routine calcium and vitamin D supplementation policy with weaning or stopping the supplements once the parathyroid gland function is recovered.

If you have any concerns about Dr. Edirimanne’s post operative thyroid patient please contact us or contact Dr. Edirimanne directly (mobile or email)

Long term care of thyroid cancer patients:

Long term care of thyroid cancer patients involves the endocrine surgeon, endocrinologist and nuclear medicine physician who discuss the management in a multidisciplinary meeting.

Dr. Edirimanne follows up thyroid cancer patients in association with his endocrinology colleagues. The follow up generally involves clinical assessment, neck ultrasound and blood tests such as thyroid function tests, serum thyroglobulin (in well differentiated thyroid cancer) and other tumour markers.

If you have any concerns regarding Dr. Edirimanne’s thyroid cancer patient please contact us or contact Dr. Edirimanne directly (mobile or email)


 

Parathyroid

Primary hyperparathyroidism (PHPT):

PHPT is the most common cause of hypercalcaemia in the community. Incidence of PHPT is 3-4/1000 in general population and rises to 2-3/100 in postmenopausal women.

Even though patients with mild PHPT who are completely asymptomatic can be observed, surgery still remains the only effective long-term treatment.

The following patients will benefit from a surgical consultation

  • Very high calcium levels which itself poses a medical threat
  • Organ dysfunction associated with PHPT such as renal stones, osteoporosis or worsening osteopaenia, pancreatitis etc.
  • Patients with constellation of non-specific symptoms associated with PHPT such as aches/pains, lethargy, confusion, depression, deteriorating cognitive function, constipation etc. These patients may notice improvement in their symptoms and overall quality of life after surgery.
  • Younger patients

The following investigations help to establish the diagnosis of PHPT and rule out the causes of secondary hyperparathyroidism

  • Serum corrected calcium
  • Serum PTH
  • Serum Vitamin D
  • Serum creatinine level
  • +/- 24 hour urinary calcium excretion / urinary calcium: creatinine excretion ratio to exclude Familial Hypocalciuric Hypercalcaemia (FHH)

The following investigations help to localize the responsible parathyroid adenoma.

  • Parathyroid ultrasound
  • Sestamibi scan
  • Parathyroid CT protocol (4D parathyroid CT)

If you have a patient with hypercalcaemia and/or suspicion of primary hyperparathyroidism and would like assistance please contact us or contact Dr. Edirimanne directly (mobile or email)

Secondary hyperparathyroidism:

Some patients with secondary hyperparathyroidism as a result of end stage renal failure may benefit from parathyroid surgery. This is a decision that involves multidisciplinary input from other specialists such as renal physicians and endocrinologists.

Post-operative care after parathyroid surgery

Patients who had either Minimally Invasive Parathyroidectomy (MIP) or four-gland neck exploration are usually discharged home next day. They have steri-strip® dressing and a Prolene® stich that needs to be removed 5 days after surgery. They will be seen at Dr. Edirimanne’s rooms in 1-2 weeks and again in 3-6 months with serum corrected Ca, PTH and Vitamin D blood tests.

If you have any concern regarding Dr. Edirimanne’s post-operative parathyroid patient please contact us or contact Dr. Edirimanne directly (mobile or email)
