Patients with compressive neuropathy of the ulnar nerve typically describe numbness and tingling of the ulnar-sided digits of the hand, classically in the small finger and ulnar aspect of the ring finger. Among the general population, symptoms usually begin intermittently and are often worse at night, particularly if the elbow is flexed while sleeping. As the disease progresses, paraesthesia may occur more frequently and during the daytime.

Allergic bronchopulmonary aspergillosis (ABPA) is a form of lung disease that occurs in some people who are allergic to Aspergillus. With ABPA, this allergic reaction causes the immune system to overreact to Aspergillus leading to lung inflammation. ABPA causes bronchospasm (tightening of airway muscles) and mucus build-up resulting in coughing, breathing difficulty and airway obstruction.

Treatment of ABPA aims to control inflammation and prevent further injury to your lungs. ABPA is a hypersensitivity reaction that requires treatment with oral corticosteroids. Inhaled steroids are not effective. ABPA is usually treated with a combination of oral corticosteroids and anti-fungal medications. The corticosteroid is used to treat inflammation and blocks the allergic reaction. Examples
of corticosteroids include: prednisone, prednisolone or methylprednisolone. Inhaled corticosteroids alone – such as used for asthma treatment – are not effective in treating ABPA. Usually treatment with an oral corticosteroid is needed for months.

The second type of therapy used is an anti-fungal medication, like itraconazole and voriconazole. These medicines help kill Aspergillus so that it no longer colonizes the airway. Usually one of these drugs is given for at least 3 to 6 months. However, even this treatment is not curative and can have side effects.

Pulsus alternans is the alternation of one strong and one weak beat without a change in the cycle length. It occurs most commonly in heart failure due to increased resistance to LV ejection, as occurs in hypertension, aortic stenosis, coronary atherosclerosis, and dilated cardiomyopathy. Pulsus alternans is usually associated with an S3 gallop, which is associated with a poor prognosis. It usually disappears with treatment of the heart failure.

Pneumococcal meningitis is the most common and severe form of bacterial meningitis. Fatality rates are substantial, and long-term sequelae develop in about half of survivors. Disease outcome has been related to the severity of the proinflammatory response in the subarachnoid space. The complement system, which mediates key inflammatory processes, has been implicated as a modulator of pneumococcal meningitis disease severity in animal studies. C5 fragment levels in cerebrospinal fluid (CSF) of patients with bacterial meningitis correlated with several clinical indicators of poor prognosis.

Gamma delta T cells are of low abundance in the body, are found in the gut mucosa, skin, lungs and uterus, and are involved in the initiation and propagation of immune responses. Their ligands are not known in detail, but the gamma delta T cell receptors recognise intact proteins rather than MHC-presented peptides. Like alpha beta T cells, they develop in the thymus.

A precordial thumb is not routinely recommended because of its very low success rate for cardioversion of a shockable rhythm. It’s only recommended when there is a delay in getting the defibrillator.

Reduced conduction velocity is associated with demyelinating neuropathies. An abnormally slow response is associated with very proximal disease, i.e. radiculopathies. Delayed P100 latency is a feature of performing visual evoked potentials in those with optic nerve disease. Conduction block is usually associated with certain types of demyelinating neuropathy.

Flashes of light, presence of floaters and loss of vision (often described as a black curtain closing in on the visual field) are symptoms that strongly indicate retinal detachment. The fundoscopy findings of retinal tears support this diagnosis. Therefore, surgery of retina must be done to treat this patient.

According to latest NICE guidelines, patients with isolated atrial septal defects do not require prophylactic antibiotics originally used in prevention of infective endocarditis in dental procedures.

Seasonal affective disorder (SAD) is a type of depression that’s related to changes in seasons. SAD begins and ends at about the same time every year. For most people with SAD, the symptoms start in the fall and continue into the winter months, sapping the person’s energy and making him feel moody. Less often, SAD causes depression in the spring or early summer.

Treatment for SAD may include light therapy (phototherapy), medications and psychotherapy.

Signs and symptoms of SAD may include:
Feeling depressed most of the day, nearly every day
Losing interest in activities you once enjoyed
Having low energy
Having problems with sleeping
Experiencing changes in your appetite or weight
Feeling sluggish or agitated
Having difficulty concentrating
Feeling hopeless, worthless or guilty
Having frequent thoughts of death or suicide.

Seasonal affective disorder is diagnosed more often in women than in men. And SAD occurs more frequently in younger adults than in older adults.

Factors that may increase your risk of seasonal affective disorder include:
Family history. People with SAD may be more likely to have blood relatives with SAD or another form of depression.
Having major depression or bipolar disorder. Symptoms of depression may worsen seasonally if you have one of these conditions.
Living far from the equator. SAD appears to be more common among people who live far north or south of the equator. This may be due to decreased sunlight during the winter and longer days during the summer months.

Normal distribution describes the spread of many biological and clinical measurements. Usually, 68.3% lies within 1 standard deviation (SD) of the mean, 95.4% lies within 2 SD of the mean and 99.7% lies within 3 SD of the mean.

Vitamin B12 is mostly used in the body for the development of red blood cells and maintenance of the nervous system. It is actively absorbed in the terminal ileum after binding to the intrinsic factor (IF) which is secreted from the parietal cells of stomach. Moreover, a small amount is also passively absorbed without being bound to IF.

Vitamin B12 deficiency is characterised by sore tongue and mouth, mood disturbances, ataxia, and macrocytic anaemia. Its causes include poor diet, impaired absorption (due to disorders of terminal ileum), pernicious anaemia, and post-gastrectomy. While managing this condition, if the person is also deficient in folic acid, then it is important to treat the B12 deficiency first in order to avoid precipitating subacute combined degeneration of the cord.

TNF-alpha inhibitors are known to ameliorate the symptoms and disease activity of Arthritis mutilans (a rare and severe form of psoriatic arthritis), by disabling the cytokines that are involved in inflammation and joint destruction. From the mentioned choices, this would be the most effective option. Methotrexate is the most commonly used DMARD, followed by sulfasalazine used in mild to moderate forms of psoriatic arthritis but has not shown much efficacy in arthritis mutilans. Phototherapy, narrowband UVB light therapy can be very effective in clearing skin lesions.

Long-term oxygen therapy (LTOT) ≥ 15 h/day improves survival in hypoxemic chronic obstructive pulmonary disease (COPD). It significantly helps in reducing pulmonary hypertension associated with COPD and treating underlying pathology of future heart failure. There is little to no benefit of oxygen therapy for less than 15 hours.

In adults, the most common symptom of meningitis is a severe headache, occurring in almost 90% of cases of bacterial meningitis, followed by nuchal rigidity (the inability to flex the neck forward passively due to increased neck muscle tone and stiffness). Other signs commonly associated with meningitis include photophobia (intolerance to bright light) and phonophobia (intolerance to loud noises).
In the United Kingdom empirical treatment consists of a third-generation cefalosporin such as cefotaxime or ceftriaxone. In the USA, where resistance to cefalosporins is increasingly found in streptococci, addition of vancomycin to the initial treatment is recommended. Penicillins, cephalosporins, carbapenems and monobactams all act via inhibition of cell wall synthesis.

This patient has Klumpke’s paralysis due to damage to the T1 nerve root. This root eventually supplies the median and ulnar nerves. The ulnar nerve supplies all of the intrinsic hand muscles except for those of the thenar eminence and the first and second lumbricals, which are innervated by the median nerve.

According to NICE guidelines (2013) all people who have had an acute MI treatment should be offered with ACE inhibitor, dual antiplatelet therapy (aspirin plus a second antiplatelet agent), a beta-blocker and a statin.

The history gives you a woman who is on inhaled steroid therapy. It is always a good idea for patients to rinse their mouths well after using inhaled steroids. Odynophagia (pain on swallowing) is a symptom of oesophageal candidiasis, which is the most likely answer given the steroids. Typically, you might see this in someone who is immunocompromised (classically, in HIV+ patients).

Results of a randomized trial confirm that the antidepressant sertraline can be used safely in patients with recent MI or unstable angina and is effective in relieving depression in these patients.

There are theoretical reasons for believing that selective serotonin reuptake inhibitors (SSRIs), widely used to treat depression, might increase the risk of gastrointestinal bleeding. Gastroprotective drugs are advocated for high risk patients taking non-steroidal anti-inflammatory drugs, another class of drug that causes gastrointestinal bleeding.

Serotonin is released from platelets in response to vascular injury and promotes vasoconstriction and a change in the shape of the platelets that leads to aggregation. Platelets cannot themselves synthesise serotonin. SSRIs inhibit the serotonin transporter, which is responsible for the uptake of serotonin into platelets. It could thus be predicted that SSRIs would deplete platelet serotonin, leading to a reduced ability to form clots and a subsequent increase in the risk of bleeding.

The well established association between nonsteroidal anti-inflammatory drugs and upper gastrointestinal bleeding is estimated to result in 700-2000 deaths/year in the UK. This has led to the recommendation that patients in high risk groups should receive gastroprotection in the form of an H2 antagonist, proton pump inhibitor (lansoprazole), or misoprostol.

Proton pump inhibitors have been shown to reduce endoscopically diagnosed mucosal damage and heal ulcers induced by non-steroidal anti-inflammatory drugs but not to reduce the incidence of severe gastrointestinal bleeds.
