Veterinary Medicine Specialists
Internal Medicine is the medical specialty concerned with the diagnosis, management and nonsurgical treatment of unusual or serious diseases. The types of diseases seen by internal medicine are wide and varied and include diseases of different organ systems for example: kidneys (nephrology), liver (hepatology), lungs (pulmonology), blood system (haematology), central nervous system (neurology) and immune-system (immunology) as well as diseases that may affected multiple body systems at the same time, such as infectious disease or cancer.
Many animals don’t present with signs obviously relating to a specific body system or disease like vomiting, diarrhoea, coughing, excessive drinking, malaise, weight loss/weight gain, anaemia and fever. Sometimes, if a case is found to have a non-medical disease, and, for example, needs surgery or cancer treatment, they can easily be referred to another service within Perth Veterinary Specialists for ongoing treatment.
1. Rotating internship in Internal Medicine, Emergency and Medical Oncology, 1 year fixed term position, commencing each January.
The intern positions are offered each year and open to all veterinarians. Students expecting to graduate at the completion of the calendar year are encouraged to apply. Applications close in September each year.
What is Internal Medicine?Internal Medicine is the medical specialty concerned with the diagnosis, management and nonsurgical treatment of unusual or complicated diseases. The types of diseases seen by internal medicine are wide and varied and include diseases of different organ systems for example: kidneys (nephrology), liver (hepatology), lungs (pulmonology), blood system (haematology), central nervous system (neurology) and immune-system (immunology) as well as diseases that may affected multiple body systems at the same time, such as infectious disease or cancer. Many animals show signs like vomiting, diarrhoea, coughing, excessive drinking, malaise, weight loss/weight gain, anaemia and fever that don’t obviously relate to a specific body system or disease. Sometimes, if a case is found to have a non-medical disease, and, for example, needs surgery or cancer treatment, it may be transferred to another service within Perth Veterinary Specialists for ongoing treatment.
ThoracocentesisThoracocentesis is essential for the diagnosis and management of animals with pleural effusions (fluid surrounding the lungs). Chest drain placement is used commonly in the management of conditions such as pyothorax (pus around the lungs).
Treatment of fungal nasal diseaseFungal disease of the nasal cavity, often due to Aspergillus and Cryptococcus species, is common in WA. Diagnosis is often aided by rhinoscopy (see endoscopy section above) and treatment of Aspergillosis requires applying anti-fungal medication directly to the nasal cavity and frontal sinuses.
Bone Marrow SamplingWhy is bone marrow collected and examined? The bone marrow produces many of the cells found in blood, including red blood cells, white blood cells and platelets. If abnormalities with any of these components are detected during blood sampling, examination of the bone marrow may be required to investigate the problem. What sorts of problems justify a bone marrow evaluation? The most common reason for examining the bone marrow is a shortage of a particular cellular element in the blood. Examining the bone marrow can help determine the cause and may help to predict what the outcome might be. Bone marrow evaluation may also be done to look for certain types of cancer. Some cancers arise in the bone marrow and others may spread to there. Examination of the bone marrow gives a better understanding of the cancer. Which bone is the marrow collected from? Although many bones contain marrow, samples are routinely collected from the front leg, just below the shoulder. Other sites where the sample is commonly collected from include the hip bone and the top of the thigh bone. How is the sample collected? At the start of the procedure, pets are deeply sedated so that they will remain calm and still during the procedure. This sedative includes pain killers which will provide comfort and ensure no pain is felt during or after the procedure. A small area of hair is clipped away from the skin and this area is surgically prepared, meaning it is cleansed and disinfected. Local anaesthetic is placed under the skin to desensitise the area. A small nick is made in the skin with a sterile scalpel blade and a needle is inserted to take a sample of bone marrow. This small skin opening is then closed with tissue glue which will fall off by itself once the wound has healed. The sample, called a bone marrow aspirate, is spread on a glass slide, dried, stained with special dyes and examined under the microscope. What is involved in marrow evaluation? Marrow evaluation is complex and requires specialist interpretation. Information gained includes how active the marrow is, what cells are present and in what proportion, the presence of abnormal cells and any other details that may explain the abnormalities noted in the patient.
EndoscopyEndoscopy is a minimally invasive diagnostic procedure that is used to assess the interior surfaces of an organ. The endoscope can be a rigid or flexible tube which provides an image of the desired organ, but more importantly also enables biopsies to be taken or the removal of foreign objects. Unlike in human medicine our feline and canine friends require general anaesthesia for this procedure. Endoscopy, however, is considered safe as complications from the procedure are uncommon. At Perth Veterinary Specialists we are equipped to perform endoscopy and endoscopic procedures in the following areas:
- Upper and lower gastrointestinal endoscopy and biopsy
- Oesophageal foreign body removal- small foreign objects in the stomach may also sometimes be removed by endoscopy but some require surgical removal.
- Dilation of oesophageal strictures
- Percutaneous endoscopic gastrotomy (PEG) tube placement- to allow feeding in patients with oesophageal disease
- Bronchoscopy (examination of the airways) and bronchoalveolar lavage (sampling cells from the airways)
- Rhinoscopy (examination of the nasal cavity and nasopharynx) and biopsy of nasal tissue
Medical Assessment of Complex CasesWe will happily accept referrals for investigations of all medical problems, no matter how complicated they are. The following are examples of the types of cases we love to be able to help with:
- Endocrine cases- for example uncontrolled diabetes mellitus, suspected Cushing’s disease, electrolyte abnormalities and investigations of polydipsia (increased thirst).
- Pyrexia (fever) of unknown origin
- Neurological cases for example animals presenting with seizures, vestibular signs or neck pain
- Respiratory disease including investigations of coughing, respiratory distress, pleural effusions
- Nasal disease- cats and dogs with sneezing, nasal discharge and/ or epistaxis (nasal bleeding)
- Liver disease- investigations of jaundice and the management of animals with portosystemic shunts
- Cardiology cases- including investigations of heart murmurs and treatment of heart failure or arrhythmias.
- Urogenital disease such as incontinence and recurrent urinary tract infections.
For Pet OwnersAt Veterinary Medicine Specialists we are equipped with the knowledge and expertise to perform the ‘detective’ work required to establish a diagnosis for your pet which results in the ability to treat your pet as effectively as possible. In order to have an appointment with any of the specialists at Perth Veterinary Specialists, you must be referred by your own vet. They are in the best position to determine if your pet needs referral and to which speciality. The referral procedure is simple, and generally only requires a phone call for an appointment and a referral form from your vet. Things to remember for your appointment:
- It is wise not to feed your pet on the day of referral as fasting is required before some procedures, such as blood samples and ultrasound. You should however provide free access to water at all times. In certain circumstances it may not be appropriate to starve your pet for such a long period, for example if your pet is young or has a particular condition such as diabetes mellitus. In any case, if you are at all concerned about fasting your pet overnight, please get in touch with us and we will be happy to advise you.
- Please bring with you any medication your pet is currently receiving.
- Your vet may ask you to bring with you referral information for us containing your pet’s history and any blood test results or x-rays.
