The patient has Meigs syndrome. Meigs syndrome is defined as a triad of benign ovarian tumour with ascites and pleural effusion that resolves after resection of the tumour. Ovarian fibromas constitute the majority of the benign tumours seen in Meigs syndrome.

Tumour markers can be divided into:
1. Monoclonal antibodies
CA 125: Ovarian cancer, primary peritoneal cancer
CA 19-9: Pancreatic cancer
CA 15-3: Breast cancer

2. Tumour specific antigens
Prostate specific antigen (PSA): Prostatic carcinoma
Alpha-feto protein (AFP): Hepatocellular carcinoma, teratoma
Carcinoembryonic antigen (CEA): Colorectal cancer
S-100: Melanoma, schwannomas
Bombesin: Small cell lung carcinoma, gastric cancer

3. Enzymes
Alkaline phosphatase (ALP)
Neuron specific enolase (NSE)

4. Hormones
Calcitonin
Antidiuretic hormone (ADH)
Human chorionic gonadotropin (hCG)

The given clinical scenario is highly suggestive of a borderline personality disorder.

Borderline personality disorder is marked out by instability in moods, behaviour, and relationships. The diagnosis is confirmed by the presence of at least 5 of the following symptoms;
1) Extreme reactions including panic, depression, rage, or frantic actions to abandonment, whether real or perceived
2) A pattern of intense and stormy relationships with family, friends, and loved ones, often veering from extreme closeness and love to extreme dislike or anger
3) Distorted and unstable self-image or sense of self, which can result in sudden changes in feelings, opinions, values, or plans and goals for the future (such as school or career choices)
4) Impulsive and often dangerous behaviours, such as spending sprees, unsafe sex, substance abuse, reckless driving, and binge eating
5) Recurring suicidal behaviours or threats or self-harming behaviour, such as cutting, intense and highly changeable moods, with each episode lasting from a few hours to a few days
6) Chronic feelings of emptiness and/or boredom
7) Inappropriate, intense anger or problems controlling anger
8) Having stress-related paranoid thoughts or severe dissociative symptoms, such as feeling cut off from oneself, observing oneself from outside the body, or losing touch with reality.

Other options:
There are no features consistent with endogenous depression, such as early morning wakening or loss of appetite.
There are also no features consistent with hypomania such as pressure of speech, a flight of ideas, or over-exuberant behaviour.
The lack of history of drug abuse rules out drug-induced psychosis.
An anti-social personality disorder is characterized by a failure to conform to social norms and repeated lawbreaking. There is consistent irresponsibility, impulsivity, and disregard for both their safety and that of others. This is not the case in the given scenario.

A t test is a type of statistical test that is used to compare the means of two groups. It is one of the most widely used statistical hypothesis tests in pain studies. There are two types of statistical inferences: parametric and nonparametric methods. Parametric methods refer to a statistical technique in which one defines the probability distribution of probability variables and makes inferences about the parameters of the distribution. In cases in which the probability distribution cannot be defined, nonparametric methods are employed. T tests are a type of parametric method; they can be used when the samples satisfy the conditions of normality, equal variance, and independence. In this case the data is parametric, and they belong to the same patients, so a paired t test should be used.

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.

Leaking of cerebrospinal fluid from the dura is the most likely explanation for post-lumbar puncture headaches. It is thought that ongoing leak of cerebrospinal fluid (CSF) through the puncture site causes ongoing CSF loss, leading to low pressure. A post-LP headache is typically frontal or occipital and occurs within three days. It is normally associated with worsening on standing and improvement when lying down. Treatment in severe cases includes an epidural blood patch, but most resolve on their own.

The dendritic ulceration seen on fluorescein staining of the eye is pathopneumonic for keratitis caused by HSV (herpes simplex virus). Presentation is that of blepharoconjunctivitis. Treatment is required, the treatment is typically topical acyclovir. Topical steroids can make the infection worse. The other answer choices would not have this dendritic pattern seen on fluorescein staining.

Stopping smoking is the single most effective non-pharmacological intervention which will reduce future ischaemic events. But the rest of the responses are also important interventions with regards to reducing future ischaemic events.

Occupational asthma (OA) could be divided into a nonimmunological, irritant-induced asthma and an immunological, allergy-induced asthma. In addition, allergy-induced asthma can be caused by two different groups of agents: high molecular weight proteins (>5,000 Da) or low molecular weight agents (<5,000 Da), generally chemicals like the isocyanates.
Isocyanates are very reactive chemicals characterized by one or more isocyanate groups (–N=C=O). The main reactions of this chemical group are addition reactions with ethanol, resulting in urethanes, with amines (resulting in urea derivates) and with water. Here, the product is carbamic acid which is not stable and reacts further to amines, releasing free carbon dioxide.

Diisocyanates and polyisocyanates are, together with the largely nontoxic polyol group, the basic building blocks of the polyurethane (PU) chemical industry, where they are used solely or in combination with solvents or additives in the production of adhesives, foams, elastomers, paintings, coatings and other materials.

The complex salts of platinum are one of the most potent respiratory sensitising agents having caused occupational asthma in more than 50% of exposed workers. Substitution of ammonium hexachlor platinate with platinum tetra amine dichloride in the manufacture of catalyst has controlled the problem in the catalyst industry. Ammonium hexachlorplatinate exposure still occurs in the refining process.

Rosin based solder flux fume is produced when soldering. This fume is a top cause of occupational asthma.

Bakeries, flour mills and kitchens where flour dust and additives in the flour are a common cause of occupational asthma.

Cadmium was not found to cause occupational asthma.

Given the symptoms described in a 31-year-old homosexual male, along with the findings of weight loss, blurred vision, and retinal hemorrhage, the single most appropriate option to consider is HIV/AIDS.

HIV/AIDS can manifest with a wide range of symptoms, including unintentional weight loss and blurred vision. Retinal hemorrhage can also occur as a complication of HIV/AIDS, particularly in advanced stages when the immune system is severely compromised.

In this case, it’s important to conduct further diagnostic tests, including HIV testing, to confirm the diagnosis. Additionally, prompt initiation of antiretroviral therapy (ART) is crucial for managing HIV/AIDS and preventing further complications. Referral to an infectious disease specialist for comprehensive management is recommended.

Impetigo appears more commonly on the face than other exposed areas like the limbs. Its blisters are clustered and may have a fluid discharge.
