After the exposure to chickenpox while pregnant, even if the patient is negative for antibodies she requires immunoglobulin to prevent further issues.

The major delayed problem with radiotherapy is the development of secondary cancers. This risk begins to appear ten years after therapy.

Hemiballismus is a movement disorder which manifests as unilateral involuntary flinging movements of the proximal upper limbs. The lesion is located in the ipsilateral subthalamic nucleus.

A prominent A wave is observed in the jugular venous pulse and this indicates the presence of established pulmonary hypertension. In addition the pulmonic component of the second heart sound (P2) may be increased and the P2 may demonstrate fixed or paradoxical splitting. The signs of right ventricular failure include a high-pitched systolic murmur of tricuspid regurgitation, hepatomegaly, a pulsatile liver, ascites, and peripheral oedema.

The main cardiovascular manifestations associated with Marfan’s syndrome are aortic dilatation and mitral valve prolapse.

Given that he has diverticula in the clinical scenario combined with his presenting symptoms, it is likely that he has diverticular disease. A low fibre diet would support this diagnosis. Acute diverticulitis would require treatment with antibiotics. Depending on the severity (Hinchey classification) would determine if he needs oral or IV antibiotics, hospital admission or outpatient treatment. Sometimes abscesses or micro perforations occur, which typical require drainage and possibly surgical intervention. Diverticular disease is clearly a better answer than other possible answer choices, simply based on the symptoms presented in the prompt (and mention of low fibre).

Patients with diabetes often develop ophthalmic complications, the most common and potentially most blinding of these complications is diabetic retinopathy.
The following are the 5 stages in the progression of diabetic retinopathy:
1. Dilation of the retinal venules and formation of retinal capillary microaneurysms.
2. Increased vascular permeability.
3. Vascular occlusion and retinal ischemia.
4. Proliferation of new blood vessels on the surface of the retina.
5. Vitreous haemorrhage and contraction of the fibrovascular proliferation.
The first 2 stages of diabetic retinopathy are known as background or nonproliferative retinopathy. Initially, the retinal venules dilate, then microaneurysms (tiny red dots on the retina that cause no visual impairment) appear. As the microaneurysms or retinal capillaries become more permeable, hard exudates appear, reflecting the leakage of plasma.

Mild nonproliferative diabetic retinopathy (NPDR) or background diabetic retinopathy is indicated by the presence of at least 1 microaneurysm, while neovascularization is the hallmark of Proliferative Diabetic Retinopathy (PDR).

The obturator nerve is compressed due to the ovarian mass, this causes pain in the inner thigh because it innervates this area.

The Diffuse Infiltrative Lymphocytosis Syndrome (DILS) is a rare multisystemic syndrome described in HIV-infected patients. It is characterised by CD8(+) T-cell lymphocytosis associated with a CD8(+) T-cell infiltration of multiple organs. DILS is usually seen in uncontrolled or untreated HIV infection but can also manifest itself independently of CD4(+) T-cell counts. The syndrome may present as a Sjögren-like disease that generally associates sicca signs with bilateral parotiditis, lymphadenopathy, and extra glandular organ involvement. The latter may affect the lungs, nervous system, liver, kidneys, and digestive tract. Anomalies of the respiratory system are often identified as lymphocytic interstitial pneumonia. Facial nerve palsy, aseptic meningitis or polyneuropathy are among the more frequent neurological features. Hepatic lymphocytic infiltration, lymphocytic interstitial nephropathy and digestive tract lymphocytic infiltration account for more rarely noted complications. Sicca syndrome, organomegaly and/or organ dysfunction associated with polyclonal CD8(+) T-cell organ-infiltration are greatly suggestive of DILS in people living with HIV.

Coronary artery disease and myocardial infarction can be excluded with a negative angiogram and a slightly elevated troponin. Hypertrophic cardiomyopathy can be excluded with cardiovascular MR findings. Left ventricular aneurysm usually occurs following a myocardial infarction, but there is no positive history for that. The characteristic findings on cardiovascular MR confirms the diagnosis of Takotsubo cardiomyopathy.
