Endometrial hyperplasia most often is caused by excess oestrogen without progesterone. If ovulation does not occur, progesterone is not made, and the lining is not shed. The endometrium may continue to grow in response to oestrogen. The cells that make up the lining may crowd together and may become abnormal. This condition, called hyperplasia, may lead to cancer in some women. Endometrial hyperplasia usually occurs after menopause, when ovulation stops and progesterone is no longer made. It also can occur during peri-menopause, when ovulation may not occur regularly. Listed as follows are other situations in which women may have high levels of oestrogen and not enough progesterone:
– Use of medications that act like oestrogen
– Long-term use of high doses of oestrogen after menopause (in women who have not had a hysterectomy)
– Irregular menstrual periods, especially associated with polycystic ovary syndrome or infertility
– Obesity

Transvaginal ultrasound may be done to measure the thickness of the endometrium. To exclude carcinoma an endometrial biopsy, dilation and curettage, or hysteroscopy may be done.

According to this presentation the most likely diagnosis is borderline personality disorder. The patient has impulsivity, self-harm and instability of interpersonal relationships, which are suggestive of borderline personality disorder. The history is not adequate to diagnose the other given conditions.

From a metabolic perspective, the functional unit is the hepatic acinus (terminal acinus), each of which is centred on the line connecting two portal triads and extends outwards to the two adjacent central veins. The periportal zone I is nearest to the entering vascular supply and receives the most oxygenated blood, making it least sensitive to ischemic injury while making it very susceptible to viral hepatitis. Conversely, the centrilobular zone III has the poorest oxygenation, and will be most affected during a time of ischemia.

Pregnant women need to get enough folic acid. The vitamin is important to the growth of the foetus’s spinal cord and brain. Folic acid deficiency can cause severe birth defects known as neural tube defects. The Recommended Dietary Allowance (RDA) for folate during pregnancy is 600 micrograms (µg)/day.

Erotomania is a condition in which one person, especially ladies, deludes themselves into thinking that there is another person/man, who is in love with them and often sends them gifts and other valuables.

Lorazepam is known to cause respiratory depression and finally apnoea as a side effect.

The portal vein is usually formed by the confluence of the superior mesenteric and splenic veins and also receives blood from the inferior mesenteric, gastric, and cystic veins.

Cervical cancer results from genital infection with HPV. PV infections can be transmitted via nonsexual routes, but the result from sexual contact. So the best contraceptive method in relation to prevention of cervical cancer is the barrier method. But it will not prevent cervical cancer a 100%.

Arterial ischemia ulcers present with many of the symptoms observed in this patient: ulcer on the lower extremities, pain, swelling, yellow sores, a punched-out appearance, the foot turning red when dangling from a bed. Smoking a lot is also known to be a causative factor here. This type of ulcer develops due to damage to the arteries caused by a lack of blood flow to the tissue – they are also deep wounds. Venous ischemic ulcers usually form in the knee or inner ankle area as opposed to the foot.

Symptoms of this patient are strong indications of cranial nerve damage most likely caused by a tumour or mass compressing the nerve. Therefore, the best diagnostic measure for this case is an MRI scan that may fully visualize the extent of damage and the size of the tumour or mass that may be responsible.

Lymphedema is most commonly the result of removal or damage to lymph nodes.

West Nile virus is an RNA virus transmitted by the Culex species of mosquitoes. It is mostly prevalent in South America, Africa and some parts of Europe. Clinically it presents with high grade fever, headache, abdominal pain, anorexia and a morbilliform rash over the body. It can also lead to meningitis, encephalitis and flaccid paralysis by affecting the anterior horn cells, a process suggesting similarity to poliomyelitis. It can be fatal if not treated abruptly. Studies suggest that it can be transferred from mother to offspring. New-borns may present with encephalitis, chorioretinitis and wide spread brain damage. Patients suffering from West Nile virus can be effectively treated with interferon, IV immunoglobulin and Ribavirin.

DiGeorge syndrome usually presents at a young age with abnormal faces. Chest x-ray is characterised by an absent thymic shadow and recurrent infections due to an abnormal T-cell mediated immune response. Sometimes it presents by convulsions of the new-born due to hypocalcaemia as a result of a malfunctioning parathyroid gland and low levels of PTH.

Symptoms of anal fissure include sharp pain in the anal area upon defecation or anal stimulation. It may also cause burning or itching as well as visible fresh blood on the stools or on the toilet paper. It is usually visible upon inspection.

Bendroflumethiazide is known to cause photosensitive rash as part of an allergic reaction during which the person might also have wheezing, chest tightness or dyspnoea. The rash typically occurs on the areas of body exposed to the sun, like the back, hands, arms and legs.
Comparatively, digoxin produces a rash that comprises of nearly the whole body.
Atenolol may also cause skin rash but that is not photosensitive.
Clopidogrel might produce an non-photosensitive urticarial rash.
Ezetimibe causes a severe allergic reaction but only rarely. This rash is also non-photosensitive and is in the form of blisters, associated with itching.

A renal scan is important in the diagnosis of early renal damage, acute or chronic nephropathies and nephrovascular disease. Renal resistive index (RRI) which is measured by Doppler sonography, is proved to be a marker of renal disease onset and progression. Young hypertension with microalbuminuria is an indication for a renal scan to identify the possible aetiology.

The presentation is suggestive of nephrotic syndrome. A trial of corticosteroids is the first step in treatment of idiopathic nephrotic syndrome. Diuretics are useful in managing symptomatic oedema. Cyclosporin and cyclophosphamide are indicated in frequently relapsing and steroid dependant disease.

Diagnostic indications for cystoscopy include the following: evaluation of patients with voiding symptoms (storage or obstructive), gross or microscopic haematuria, urologic fistulas, urethral or bladder diverticula and congenital anomalies in paediatric population.

Melanoma is more common in men than women. Reasons for the disease includes: UV light and genetic predisposition or mutations. Diagnosis is by biopsy and analysis of any skin lesion that has signs of being potentially cancerous.
Early warning signs of melanoma ABCDE:
Asymmetry
Borders (irregular with edges and corners)
Colour (variegated)
Diameter (greater than 6 mm)
Evolving over time

Lesions in L5-S1 region leads to altered sensation on the lateral side of calf and foot, along with back pain. There might be difficulty in extension of the leg, foot inversion, plantar flexion and toe flexion, as muscles controlling these functions are supplied by S1.

Blood glucose should be evaluated immediately in order to investigate for diabetic coma triggered by hyperglycaemia or hypoglycaemia.

Sjogren syndrome is characterised by keratoconjunctivitis sicca, dry mouth and generalised body aches. It is one of the connective tissue diseases and has positive auto Ro and La antibodies.

Although viral infection is the most common identifiable cause of acute pericarditis, the condition may be associated with many diseases. Non-viral causes of pericarditis include bacterial infection, MI, chest trauma, and neoplasm. Post–MI pericarditis may develop two to four days after an acute infarction and results from a reaction between the pericardium and the damaged adjacent myocardium. Dressler’s syndrome is a post–MI phenomenon in which pericarditis develops weeks to months after an acute infarction; this syndrome is thought to reflect a late autoimmune reaction mediated by antibodies to circulating myocardial antigens.

Pneumocystis carinii pneumonia, is an opportunistic fungal lung infection occurring almost exclusively in immunocompromised individuals. In 50% of cases, PCP is the first manifestation of AIDS (acquired immune deficiency syndrome), but it may be caused by other immunodeficiency disorders. PCP should be suspected in patients with a history of progressive dyspnoea and a dry cough with resistance to standard antibiotic treatment. Signs that support this diagnosis include a CD4 count < 200/μL, an increased beta-D-glucan level, and diffuse bilateral infiltrates on chest x-ray. Management of PCP includes high-dose trimethoprim/sulfamethoxazole (TMP/SMX), treatment of the underlying immunodeficiency disorder, and steroids in the case of severe respiratory insufficiency. TB is less likely to be present in this case as ESR is relatively low and chest x-ray appeared normal.

Neuroleptic Malignant Syndrome is a life-threatening condition associated with neuroleptic medications. It is characterized by severe muscular rigidity, hyperthermia, autonomic instability (tachycardia, tachypnoea etc) and changes in the level of consciousness. It usually occurs 4-14 days after the start of therapy. Renal failure and elevated creatinine kinase are also associated with this condition.

Macular disease can affect central vision at any stage of diabetic retinopathy and may be seen in type 2 diabetic patients. Diabetic retinopathy affects up to 80 percent of those who have had diabetes for 20 years or more. Macular oedema occurs when damaged blood vessels leak fluid and lipids onto the macula, the part of the retina that lets us see detail. The fluid makes the macula swell, which blurs vision.

Tenderness is usually suggestive of a benign breast mass such as a breast abscess. Ultrasound is used to distinguish solid from cystic structures and to direct needle aspiration for abscess drainage.

This scenario represents anorexia nervosa disorder, a psychological disorder. Extreme weight loss with a strict diet can lead to deficiency of many nutrients like magnesium and calcium. This can also cause amenorrhea.

Aminoglycosides can induce acute kidney injury by damaging the cells of the proximal tubule which is its site of reabsorption after glomerular filtration. When the aminoglycoside is administered less frequently, the kidney has more time to recover by eliminating the drug and preventing its accumulation and possible toxic effects.

The prognosis for croup is excellent, and recovery is almost always complete with complications being quite rare. The possible complications are pneumonia, bacterial tracheitis, pulmonary oedema, pneumothorax, pneumomediastinum, lymphadenitis or otitis media. Bacterial tracheitis is a life-threatening infection that can arise after the onset of an acute viral respiratory infection.
