DI

Diabetes insipidus (DI) is not related to diabetes mellitus (T1DM / T2DM), although shares similar signs/symptoms.

DI is a rare condition characterised by the production of large amounts of dilute urine (polyuria) and greatly increased thirst (polydipsia).

DI is caused by a problem with either the production or action of the hormone arginine vasopressin (AVP; also known as anti-diuretic hormone, ADH). Lack/inaction of AVP means the kidneys are unable to retain water.

There are two main forms: central DI (also known as cranial or neurogenic DI), caused by a deficiency of AVP and nephrogenic DI, caused by resistance to AVP in the kidneys (the kidneys do not respond to AVP). DI can also be related to pregnancy (gestational DI) or a problem with the body's thirst mechanism (dipsogenic DI).

GDM

Gestational diabetes mellitus (GDM) is diabetes (high blood glucose) that develops during pregnancy. GDM is usually diagnosed from a blood test 24 to 28 weeks into pregnancy. Women with GDM don’t have diabetes before their pregnancy, and it usually goes away after giving birth.

In the UK, roughly 16 out of every 100 women will develop GDM.

The most common problem associated with GDM is a large baby (macrosomia), which can make vaginal delivery more difficult and may mean caesarean section is required.

Hereditary haemorrhagic telangiectasia (HHT), also known as Osler–Weber–Rendu syndrome, is a rare autosomal dominant genetic disorder that leads to abnormal blood vessel formation:

  • Telangiectasia: in the skin and mucous membranes (red or purple spots under the skin)
  • Arteriovenous malformations (AVMs): in organs such as the lungs, liver and brain

The most common problem is nosebleeds (epistaxis), acute GI blood loss, and chronic GI blood loss, leading to IDA.

ICU/ITU

Intensive Care Unit (ICU) and Intensive Therapy Unit (ITU) are synonymous.

An ICU offers 'Level 3' care, for "Patients requiring two or more organ support (or needing mechanical ventilation alone). Staffed with one nurse per patient and usually with a doctor present in the unit 24 hours per day." (reference)

An ICU is therefore used for patients with severe or life-threatening illnesses (particularly multi-organ failure) and injuries, requiring constant care and specialist equipment, monitoring, medications and interventions.


IDA

Iron deficiency anaemia (IDA) is the most common form of microcytic anaemia.

IDA can be caused by chronic blood loss (including menstruation in pre-menopausal women or from the GI tract, such as in the case of bowel cancer), malabsorption of iron, or dietary deficiency of iron.

NICE CKS - Anaemia (IDA)

IE

Infective endocarditis (IE) is an infection of the heart's inner lining (the endocardial surface), which may include valves and chordae tendineae.

BMJ Best Practice - Infective endocarditis


IFG

IFG is Impaired Fasting Glycaemia/Hyperglycaemia. Like IGT, IFG is known as 'prediabetes'.

IFG is defined as a fasting plasma glucose between 6.1 and 6.9 mmol/L (source: NICE).

IFG is managed by lifestyle intervention.


IGT

Like IFG, IGT is a form of 'prediabetes'.

The current WHO diagnostic criteria for IGT are: a fasting plasma glucose of less than 7.0 mmol/L and a 2-hour venous plasma glucose (after ingestion of 75 g oral glucose load) of 7.8 mmol/L or greater, and less than 11.1 mmol/L. (source: NICE)

IGT is a strong risk factor for developing diabetes and cardiovascular disease, and therefore IGT is managed using lifestyle change ± medication.


ILD

Interstitial lung disease (ILD) refers to a group of diseases affecting the lung interstitium (the tissue and space around the alveoli).


IMT

Internal Medicine Training (IMT) replaced Core Medical Training (CMT) in August 2019. This new curriculum was introduced in response to the recommendations set out in the Shape of Training Report, and other drivers.

IMT forms the first three years of post-foundation training and, for the main specialties supporting acute hospital care, an indicative 12 months of further internal medicine training will be integrated flexibly with specialty training in a dual programme.

IMT aims to prepare doctors for the management of the acutely unwell patient, with an increased focus on chronic disease management, comorbidity and complexity. Generic professional capabilities (GPCs) as set out in the GMC's framework will be embedded in all curricula to emphasise the importance of these professional qualities as well as helping to promote flexibility in postgraduate training.

LMWH is cleared renally.

UTI

Urinary tract infection (UTI) is an infection in any part of the urinary system. Lower UTI affects the bladder (cystitis); upper UTI affects the ureters or kidneys (pyelonephritis).

UTI is more common in females.

Complicated UTI occurs when the urinary tract is abnormal, if a patient has a catheter (catheter-associated UTI), if the causative organisms are atypical, or if there are predisposing co-morbidities such as poorly controlled diabetes. Uncomplicated UTI is caused by typical organisms in people with a normal urinary tract and kidney function. Complicated UTI increases risk of persistent infection, treatment failure and recurrent infection (recurrent UTI).

Most UTIs can be easily treated with antibiotics, although recurrence is possible, particularly in women.

V

V/Q

Ventilation (V, air reaching the lung alveoli) / Perfusion (Q, blood reaching lung alveoli via capillaries) is an important concept in respiratory physiology.

The V/Q ratio refers to the ratio of the amount of air reaching the alveoli per minute to the amount of blood reaching the alveoli per minute. V and Q are the main determinants of blood oxygen and carbon dioxide concentration.

V/Q mismatch occurs when one or more areas of the lung receive oxygen but no/little blood flow, or they receive blood flow but no/little oxygen.

V/Q ratio can be determined using a V/Q lung scan, medical imaging using scintigraphy and medical isotopes to evaluate the circulation of air and blood within the lungs. The V/Q scan is used in preference to a CTPA for the investigation of PE in patients with kidney failure or in pregnancy, to avoid significant radiation exposure.

VF

Ventricular fibrillation (VF) is a type of cardiac arrhythmia where the heart's ventricles twitch randomly rather than contracting in a co-ordinated fashion, due to aberrant electrical activity in the ventricles.

VF results in cardiac arrest with loss of consciousness and no pulse, as the ventricles fail to pump blood around the body.

Prompt CPR and defibrillation are needed to survive VF.


VSD

Ventricular septal defect (VSD) is a form of congenital heart disease where there is a hole in the ventricular septum, between the ventricles of the heart. This hole allows blood to flow from the left side of the heart to the right, meaning a large volume of blood flows to the lungs. 

A large VSD causes high blood pressure in the pulmonary arteries (pulmonary hypertension) and means the left heart has to work harder than normal. This may lead to heart failure.

VSDs may close over time and not need treatment. Alternatively, surgery may be required. Pulmonary artery banding may be performed, allowing surgery to take place at a later date.


VTE

Venous thromboembolism (VTE) describes a blood clot that forms in a vein and travels to another location causing blockage. Typically VTE involves a clot from a DVT causing a PE.
