28 yo F presents with a thin, grayish white, foul-smelling vaginal discharge. What the diagnose?
Answers
The likely diagnosis is bacterial vaginosis (BV).
Bacterial vaginosis is a common vaginal infection characterized by a thin, grayish white, and foul-smelling vaginal discharge. It occurs when there is an imbalance in the vaginal microbiota, with an overgrowth of harmful bacteria, particularly Gardnerella vaginalis. The discharge in BV typically has a strong fishy odor, especially after intimate intercourse or washing with soap.
Other common symptoms of BV include itching, burning during urination, and mild irritation. However, it is possible to have BV without experiencing any symptoms.
To confirm the diagnosis, a healthcare provider may perform a physical examination and collect a sample of vaginal discharge for laboratory testing. Treatment often involves the use of oral or topical antibiotics, such as metronidazole or clindamycin, to restore the balance of vaginal bacteria and alleviate the symptoms.
It is important to seek medical attention for proper diagnosis and treatment, as untreated BV may increase the risk of complications, such as pelvic inflammatory disease and preterm birth in pregnant individuals.

What is a cross-sectional study design?A cross-sectional study design is a type of observational study that collects data from a group of individuals at a specific point in time. This study design is commonly used in epidemiological research to estimate the prevalence of an outcome or disease in a population and to identify potential risk factors associated with that outcome.
For example, a cross-sectional study could investigate the association between smoking and lung cancer by collecting data on smoking status and lung cancer diagnosis in a group of individuals at a specific point in time. One advantage of cross-sectional studies is that they are relatively quick and inexpensive to conduct compared to other types of observational studies.
However, cross-sectional studies have limitations. They cannot establish causality, since the exposure and outcome are measured at the same time, and they are subject to bias, including selection bias and measurement bias.

25 yo M presents with hemiparesis (after a tonic-clonic seizure) that resolves over a few hours. What the diagnose?
Answers
Based on the information provided, the most likely diagnosis for the 25-year-old male presenting with hemiparesis after a tonic-clonic seizure that resolves over a few hours is a transient ischemic attack (TIA).
A TIA is a temporary disruption in blood flow to the brain, often caused by a blood clot or narrowing of the blood vessels, which can cause symptoms similar to a stroke, including weakness or numbness on one side of the body (hemiparesis), slurred speech, and vision changes. To confirm the diagnosis, the patient will need to undergo diagnostic tests, such as a CT scan or MRI of the brain, to rule out other possible causes of hemiparesis, such as a stroke or brain tumor. Additional tests, such as blood tests, electroencephalogram (EEG), or a lumbar puncture, may also be necessary to rule out other underlying conditions that could have triggered the seizure and subsequent hemiparesis.
Once a TIA diagnosis is confirmed, the patient will need to undergo further evaluation and treatment to prevent future TIAs or strokes. This may involve lifestyle changes, such as quitting smoking, improving diet and exercise, and managing underlying health conditions like high blood pressure and diabetes, as well as medication management, such as blood thinners or cholesterol-lowering drugs. It is important for the patient to work closely with their healthcare team to develop a comprehensive treatment plan to minimize the risk of further complications.

A. 2

C. 7
D. 10
Answers
Answer:
the correct answer is B. 4.
Explanation:
According to Table 1 on page 103, brisk walking would most likely be at a MET level of 4. Therefore, the correct answer is B. 4.
This is considered moderate intensity physical activity and corresponds to an oxygen uptake of 3.5-7 mL/kg/min or approximately 4 kcal/min.
The MET (metabolic equivalent) is a unit of measurement that expresses the energy expenditure of an activity relative to the resting metabolic rate. The resting metabolic rate is defined as 1 MET, which corresponds to an energy expenditure of about 3.5 milliliters of oxygen per kilogram of body weight per minute (ml/kg/min) or about 1 calorie per kilogram of body weight per hour (kcal/kg/h).
So, a person who weighs 70 kg and brisk walks at a pace of 4 miles per hour would have an energy expenditure of about 5 METs, which corresponds to an energy expenditure of about 17.5 ml/kg/min or about 5 kcal/kg/h.

Inguinal hernia.
This is complication of ______
Answers
The complications listed, including subfertility, testicular torsion, and inguinal hernia, can all be associated with testicular cancer. Testicular cancer is a type of cancer that occurs in the testicles, which are located inside the scrotum. It is more common in young and middle-aged men and can sometimes cause no symptoms until it has spread to other parts of the body.
Subfertility, or difficulty conceiving a child, can be a complication of testicular cancer treatment such as chemotherapy or radiation therapy. These treatments can damage the sperm-producing cells in the testicles, leading to a decreased sperm count and motility. Testicular torsion, on the other hand, is a medical emergency that occurs when the testicle twists on its spermatic cord, causing a disruption in blood flow to the testicle. This can be a complication of testicular cancer or occur independently. Finally, inguinal hernias can be a complication of testicular cancer surgery. This type of hernia occurs when tissue protrudes through a weak spot in the abdominal muscles, causing a bulge in the groin or scrotum. It is important for men to perform regular self-examinations of their testicles and to seek medical attention if they notice any lumps, swelling, or other changes. Early detection and treatment of testicular cancer can help prevent these complications from occurring.
