Diagnostic criteria of PCOsAccording to the American Association of Clinical Endocrinologists, at least two of three of the criteria below are required for diagnosis of PCOS after excluding other causes of irregular bleeding and elevated androgen levels.Hyperandrogenism (clinical or laboratory)Oligo- and/or anovulationPolycystic ovaries on ultrasoundDiagnosis of PCOS is possible without the presence of ovarian cysts.Rule out any other causes of hyperandrogenism and anovulation.Blood hormone levels↑ Testosterone (both total and free) or free androgen index↑ LH (LH:FSH ratio > 2:1)Oestrogen is normal or slightly elevated A clinical picture of hyperandrogenism overrules any normal hormone levels and can fulfil a diagnostic criterium of PCOS.

Syphilis is an infectious venereal disease caused by the spirochete Treponema pallidum. Syphilis is transmissible by sexual contact with infectious lesions, from mother to foetus in utero, via blood product transfusion, and occasionally through breaks in the skin that come into contact with infectious lesions. If untreated, it progresses through 4 stages: primary, secondary, latent, and tertiary.

3,4-methylenedioxy-methamphetamine (MDMA) is a synthetic drug that alters mood and perception (awareness of surrounding objects and conditions). It is chemically similar to both stimulants and hallucinogens, producing feelings of increased energy, pleasure, emotional warmth, and distorted sensory and time perception. MDMA’s effects last about 3 to 6 hours, although many users take a second dose as the effects of the first dose begin to fade. Over the course of the week following moderate use of the drug, a person may experience:irritabilityimpulsiveness and aggressiondepressionsleep problemsanxietymemory and attention problemsdecreased appetitedecreased interest in and pleasure from sex

The risk of ischemic stroke in patients using combined oral contraceptives is increased in patients with additional stroke risk factors, including smoking, hypertension, and migraine with aura.

Most individuals with eating disorders do not receive treatment. The treatment gap may involve individuals’ attitudes about accessing various types of treatment, as well as perceived barriers to seeking treatment. Therapies to be considered for the psychological treatment of anorexia nervosa include cognitive analytic therapy (CAT), cognitive behaviour therapy (CBT), interpersonal psychotherapy (IPT), focal psychodynamic therapy and family interventions focused explicitly on eating disorders.The first step is an evidence-based self-help programme. Antidepressants may be helpful for patients with substantial concurrent symptoms of depression, anxiety, obsessions, or certain impulse disorder symptoms. They may be particularly good for patients who have not benefited from or had suboptimal response to suitable psychosocial therapy or who have a chronic, difficult course in combination with other treatments.Acute pharmacologic treatment of anorexia nervosa is rarely required. However, vitamin supplementation with calcium should be started in patients, and although oestrogen has no established effect on bone density in patients with anorexia nervosa, oestrogen replacement (i.e., oral contraceptives) has been recommended for the treatment of osteopenia. Note: Oestrogen should not be used in children (due to premature fusion of the bones).

Effective treatment can cure gonorrhoea and help prevent long-term complications. CDC recommends a single dose of 250mg of intramuscular ceftriaxone AND 1g of oral azithromycin. It is important to take all of the medication prescribed to cure gonorrhoea.

The progesterone is primarily responsible for preventing pregnancy. The main mechanism of action is the prevention of ovulation| they inhibit follicular development and prevent ovulation. Progestogen negative feedback works at the hypothalamus to decreases the pulse frequency of gonadotropin-releasing hormone. This, in turn, will decrease the secretion of follicle-stimulating hormone (FSH) and decreases the secretion of luteinizing hormone (LH). If the follicle isn’t developing, then there is no increase in the oestradiol levels (the follicle makes oestradiol). The progestogen negative feedback and lack of oestrogen positive feedback on LH secretion stop the mid-cycle LH surge. With no follicle developed and no LH surge to release the follicle, there is the prevention of ovulation. Oestrogen has some effect with inhibiting follicular development because of its negative feedback on the anterior pituitary with slows FSH secretion| it’s just not as prominent as the progesterone’s effect. Another primary mechanism of action is progesterone’s ability to inhibit sperm from penetrating through the cervix and upper genital tract by making the cervical mucous unfriendly. Progesterone induced endometrial atrophy should deter implantation, but there is no proof that this occurs.

Fertilization occurs when the sperm reaches an egg released during ovulation. At the time of fertilization, the interaction of sperm with the zona pellucida stimulates the release of calcium. This process initiates a corona reaction that prevents polyspermy.

HELLP syndrome is a complication of pregnancy characterized by haemolysis, elevated liver enzymes, and a low platelet count. It usually begins during the last three months of pregnancy or shortly after childbirth. HELLP syndrome is a life-threatening condition that can potentially complicate pregnancy. It is named for 3 features of the condition: Haemolysis, Elevated Liver enzyme levels, and Low Platelet levels. It typically occurs in the last 3 months of pregnancy (the third trimester) but can also start soon after delivery. A wide range of non-specific symptoms may be present in women with HELLP syndrome. Symptoms may include fatigue| malaise| fluid retention and excess weight gain| headache| nausea and vomiting| pain in the upper right or middle of the abdomen| blurry vision| and rarely, nosebleed or seizures. The cause of HELLP syndrome is not known, but certain risk factors have been associated with the condition. It is most common in women with preeclampsia or eclampsia. If not diagnosed and treated quickly, HELLP syndrome can lead to serious complications for the mother and baby. The main treatment is to deliver the baby as soon as possible, even if premature, if there is distress of the mother or the baby. Treatment may also include medications needed for the mother or baby, and blood transfusion for severe bleeding problems.

Ipecac, or syrup of ipecac (SOI), is a medication once used to induce vomiting. Its medical use has virtually vanished, and it is no longer recommended for routine use in toxic ingestion. The abuse of SOI as a purgative in eating disorders, however, is increasing. Ipecac has a high safety profile. Common side effects include prolonged vomiting (greater than 1 hour), lethargy, somnolence, diarrhoea, fever, irritability. More severe complications can consist of aspiration pneumonia, Mallory-Weiss tears, pneumomediastinum, and gastric rupture.The abuse of syrup of ipecac by patients with major eating disorders have been shown to have toxic effects on the skeletal and cardiac muscle.

Pubic lice are commonly referred to as ‘crabs’ because of their short, broad body (about 1 mm), and large front claws. Pubic lice infestation is diagnosed by finding a “crab” louse or eggs on hair in the pubic region or, less commonly, elsewhere on the body (eyebrows, eyelashes, beard, moustache, armpit, perianal area, groin, trunk, scalp). Although pubic lice and nits can be large enough to be seen with the naked eye, a magnifying lens may be necessary to find lice or eggs.Pubic lice are transmitted from person to person most-commonly via sexual contact, although fomites (bedding, clothing) may play a minor role in their transmission.

Combined oral contraceptive pills have an anti ovulatory function and also reduce the pain of menstruation.

Syphilis is an infectious venereal disease caused by the spirochete Treponema pallidum. Syphilis is transmissible by sexual contact with infectious lesions, from mother to foetus in utero, via blood product transfusion, and occasionally through breaks in the skin that come into contact with infectious lesions. If untreated, it progresses through 4 stages: primary, secondary, latent, and tertiary. Primary and secondary syphilis are easy to treat with a penicillin injection. Penicillin is one of the most widely used antibiotics and is usually effective in treating syphilis. People who are allergic to penicillin will likely be treated with a different antibiotic, such as:doxycyclineazithromycinceftriaxone

Although some individuals with Anorexia Nervosa exhibit no laboratory abnormalities, the semistarvation characteristic of this disorder can affect most major organ systems and produce a variety of disturbances. The induced vomiting and abuse of laxatives, diuretics, and enemas can also cause a number of disturbances leading to abnormal laboratory findings.Haematology: Leukopenia and mild anaemia are common| thrombocytopenia occurs rarely.Chemistry: Dehydration may be reflected by an elevated blood urea nitrogen (BUN). Hypercholesterolemia is common. Liver function tests may be elevated.Hypomagnesemia, hypozincaemia, hypophosphatemia, and hyperamylasaemia are occasionally found. Induced vomiting may lead to metabolic alkalosis (elevated serum bicarbonate), hypochloraemia, and hypokalaemia, and laxative abuse may cause a metabolic acidosis. Serum thyroxine levels are usually in the low-normal range| triiodothyronine levels are decreased. Hyperadrenocorticism and abnormal responsiveness to a variety of neuroendocrine challenges are common.In females, low serum oestrogen levels are present, whereas males have low levels of serum testosterone. There is a regression of the hypothalamic-pituitary-gonadal axis in both sexes in that the 24-hour pattern of secretion of luteinizing hormone (LH) resembles that normally seen in prepubertal or pubertal individuals.

Clotrimazole interferes with the ergosterol biosynthesis by decreasing ergosteron I biosynthesis, increasing membrane permeability, and disrupting membrane-bound enzyme systems.Vaginal candidiasis is an extremely common condition. Predisposing factors include:- diabetes mellitus- drugs: antibiotics, steroids- pregnancy- immunosuppression – iatrogenic

Treating persons infected with C. trachomatis prevents adverse reproductive health complications and continued sexual transmission, and treating their sex partners can prevent reinfection and infection of other partners. Treating pregnant women usually prevents transmission of C. trachomatis to neonates during birth. Chlamydia treatment should be provided promptly for all persons testing positive for infection. Treatment delays have been associated with complications (e.g. PID) in a limited proportion of women. To minimise disease transmission to sex partners, persons treated for chlamydia should be instructed to abstain from sexual intercourse for 7 days after single-dose therapy or until completion of a 7-day regimen and resolution of symptoms if present. To minimise risk for reinfection, patients also should be instructed to abstain from sexual intercourse until all of their sex partners are treated. Persons who receive a diagnosis of chlamydia should be tested for HIV, GC, and syphilis.

Boys and men with Klinefelter syndrome typically have small testes that produce a reduced amount of testosterone (primary testicular insufficiency). Testosterone is the hormone that directs male sexual development before birth and during puberty. Without treatment, the shortage of testosterone can lead to delayed or incomplete puberty, breast enlargement (gynecomastia), decreased muscle mass, decreased bone density, and a reduced amount of facial and body hair. As a result of the small testes and decreased hormone production, affected males are not generally infertile but may benefit from assisted reproductive technologies. Some affected individuals also have differences in their genitalia, including undescended testes (cryptorchidism), the opening of the urethra on the underside of the penis (hypospadias), or an unusually small penis (micropenis).

The given presentation is highly suggestive of withdrawal effect of ketamine.Ketamine is known for its unique property of inducing dissociative anaesthesia. Emergence phenomenon (as seen in the child in question) is an adverse effect that occurs during recovery from dissociative anaesthesia. The components of emergence phenomenon include a euphoric state associated with hallucinations.

Anorexia nervosa is associated with a decrease in muscle mass, which is one of the primary locations of creatinine metabolism. Due to this, plasma creatinine levels are found to be decreased in patients with anorexia. Other blood chemistry derangements in patients of anorexia nervosa include hypercortisolism, hypoglycaemia, low free T3 levels, and hypercholesterolemia.

Clinical signs of early pregnancy-Amenorrhoea-Nausea and vomiting -Breast enlargement and tenderness -Hyperpigmentation of the areola and formation of linea nigra: Most likely due to increased levels of melanocyte-stimulating hormone produced by the placenta -Increased urinary frequency-Fatigue-Cravings for or aversions to certain foods-Abdominal bloating and constipation
