DGI presents as two syndromes: 1) a bacteremic form that includes a triad of tenosynovitis, dermatitis, and polyarthralgias without purulent arthritis and 2) a septic arthritis form characterized as a purulent arthritis without associated skin lesions. Many patients will have overlapping features of both syndromes. Time from infection to clinical manifestations may range from 1 day to 3 months. There is no travel history and the rash of Lyme disease is not purulent. Reactive arthritis presents with conjunctivitis, urethritis and arthritis usually with a red hot tender and swollen joint.

This is most likely describing irritable bowel syndrome (IBS). Symptoms are either diarrhoea, constipation, or both, abdominal pain, bloating, of varying duration. It is a functional, not an organic problem, as far as research shows at this point. It is essentially a diagnosis of exclusion. Treatment is a high fibre diet with fluids. Caffeine should be avoided as this can worsen symptoms.

Salbutamol stimulates beta-2 adrenergic receptors, which are the predominant receptors in bronchial smooth muscle (beta-2 receptors are also present in the heart in a concentration between 10% and 50%).

Stimulation of beta-2 receptors leads to the activation of enzyme adenyl cyclase that forms cyclic AMP (adenosine-mono-phosphate) from ATP (adenosine-tri-phosphate). This increase of cyclic AMP relaxes bronchial smooth muscle and decrease airway resistance by lowering intracellular ionic calcium concentrations. Salbutamol relaxes the smooth muscles of airways, from trachea to terminal bronchioles.

Increased cyclic AMP concentrations also inhibits the release of bronchoconstrictor mediators such as histamine and leukotriene from the mast cells in the airway.

Bradycardia and miosis should be anticipated following the administration of anticholinesterases.

Anticholinesterase agents include the following medications:
– Pyridostigmine, neostigmine, and edrophonium which play a significant role in the diagnosis and the management of myasthenia gravis.
– Rivastigmine, galantamine and donepezil are cholinesterase inhibitors found to be significantly useful in the management of Alzheimer’s disease.

Mechanism of action and pharmacological effects:
Inhibition of cholinesterase increases the level and the duration of action of acetylcholine within the synaptic cleft.

Thus, cholinergic effects such as a reduction in heart rate (bradycardia), miosis (pupillary constriction), increased secretions, increased gastrointestinal motility and reduction in BP may occur with anticholinesterases.

Toxins such as organophosphates and carbamates also are primarily anticholinergic and cause the following typical SLUDGE symptoms:
– Salivation
– Lacrimation
– Urination
– Diaphoresis
– Gastrointestinal upset
– Emesis

The most probable diagnosis in this patient is conversion disorder.

There may be underlying tension regarding her musical career which could be manifesting as apparent limb weakness.

Conversion disorder typically involves loss of motor or sensory function. The patient doesn’t consciously feign the symptoms (factitious disorder) or seek material gain (malingering). Patients may be indifferent to their apparent disorder – la belle indifference – although this has not been backed up by studies.

Other options:
Unexplained symptoms
There are a wide variety of psychiatric terms for patients who have symptoms for which no organic cause can be found:

Somatization disorder
Multiple physical symptoms present for at least 2 years
the patient refuses to accept reassurance or negative test results

Hypochondriacal disorder
The persistent belief in the presence of an underlying serious disease, e.g. cancer.
The patient again refuses to accept reassurance or negative test results

Dissociative disorder
Dissociation is a process of ‘separating off’ certain memories from normal consciousness
Unlike conversion disorder, it involves psychiatric symptoms e.g. amnesia, fugue, stupor
Dissociative identity disorder (DID) is the new term for multiple personality disorder as is the most severe form of dissociative disorder

Munchausen’s syndrome
Also known as factitious disorder
The intentional production of physical or psychological symptoms

Malingering
Fraudulent simulation or exaggeration of symptoms with the intention of financial or another gain.

Intensive physical training and participation in competitive sports during childhood and early adolescence may affect athletes’ pubertal development.
Female athletes who do not begin secondary sexual development by the age of 14 or menstruation by the age of 16 warrant a comprehensive evaluation and treatment.
Since she is still 14, adequate diet and observation are enough.

Frequent change of eye glasses, scotoma, and mild cupping are suggestive of primary open angle glaucoma. This means that the anterior angle of the eye is normal but there is a problem in the trabecular meshwork, where the Schlemm’s Canal is not allowing the drainage of the aqueous humor. Pilocarpine should be given to the patient because it is a parasympathomimetic agent. It causes the ciliary muscle of the eye to contract, causing the trabecular meshwork to open up, allowing the aqueous humor to drain again.

Poor prognostic factors for breast cancer include:
1. Young age (<40 years)
2. Premenopausal at the time of diagnosis
3. Increased tumour size
4. High-grade tumour
5. Oestrogen and progesterone receptor-negative tumour
6. Positive lymph node status
