Polycystic ovary syndrome is an endocrine disorder and a common cause of chronic anovulation. In addition to the clinical manife
Scilla [17]

Answer:

1. Insulin resistance and diabetes

2. Metformin

Explanation:

Metformin can be used to treat polycystic ovary syndrome, especially for insulin-resistant women (insulin is a hormone that transports sugar into cells).

People with insulin resistance have high levels of this hormone in their blood and excess circulating insulin can aggravate manifestations of polycystic ovary syndrome, and also increase the risk of diabetes.

The main benefits of metformin in the treatment of polycystic ovaries is the normalization of menstrual irregularity and the restoration of ovulatory cycles.

Since most women with polycystic ovary syndrome are insulin resistant, metformin is a good treatment option in some cases.

However, the treatment of polycystic ovary syndrome should be individualized for each woman, depending on the symptoms presented and the goal to be achieved with the treatment.

A. The major etiologic factor associated with SC is ultraviolet radiation, principally UV-B.

B. Factors predisposing to SC include skin phenotype, age, male sex, outdoor occupation, rural living, and host immune status.

C. AK and SC serve as clinical dose-meters for chronic UVR exposure.

D. All of the above.

The correct answer is option D. "All of the above".

Solar cheilosis (SC) is a type of precancer of the lower lip, induced by ultraviolet light exposure, particularly by the exposure of UV-B from sunlight. However, UV-B exposure is not the only cause of SC, there are different factor that predispose to the development of this disease, including skin phenotype, age, male sex, outdoor occupation, rural living, and host immune status. Particularly because people with an outdoor occupation is  more expose to sunlight and people with an detrimental immunological condition cannot fight SC as easy as a healthy person. According to the scientific article "Epidemiology of actinic keratoses and squamous cell carcinoma" by Salasche SJ., Actinic keratosis (AK) and SC serve as clinical dose-meters for chronic UVR exposure
