Genital herpes affects the genitals, buttocks or anal area. Genital herpes is a sexually transmitted disease (STD). It affects the genitals, buttocks or anal area. Other herpes infections can affect the eyes, skin, or other parts of the body. The virus can be dangerous in newborn babies or in people with weak immune systems.

There are two types of HSV:
1. HSV Type 1 most commonly causes cold sores. It can also cause genital herpes.
2. HSV Type 2 is the usual cause of genital herpes, but it also can infect the mouth.

Ectropion (Out Turning of Eyelid)

                       Ectropion is a medical condition in which the lower eyelid turns outwards. It is also known as Out Turning of the Eyelid. In severe ectropion, the entire length of the eyelid is turned out. When ectropion is less severe, only one segment of the eyelid sags away from the eye. Artificial tears can help relieve the symptoms caused by ectropion until you can have surgery to correct the condition.

The primary cause of ectropion is the muscle weakness or tissue relaxation that occurs as part of the normal aging process. Other are :
1. Stroke
2. Skin cancer
3. Injury
4. Scar tissue from injuries or burns
5. Facial palsy
6. Birth defects due to genetic disorders like Down syndrome
7. Prior surgery or radiation treatment of the eyelids
8. Rapid weight loss

Signs and Symptoms
- Excess tearing of the eye (epiphora)
- Dry, painful eyes
- Eyelid turns outward
- Long-term (chronic) conjunctivitis
- Keratitis
- Redness of the lid and white part of the eye
- Irritation of eye.

Permanent Teeth Eruption Times (Mnemonic)

                 Tooth Eruption is a process in tooth development in which the teeth enter the mouth and become visible. It is currently believed that the periodontal ligament plays an important role in tooth eruption. The first human teeth to appear, the deciduous (primary) teeth (also known as baby or milk teeth), erupt into the mouth from around 6 months until 2 years of age.

The permanent dentition begins when the last primary tooth is lost, usually at 11 to 12 years, and lasts for the rest of a person's life or until all of the teeth are lost (edentulism). During this stage, permanent third molars (also called "wisdom teeth") are frequently extracted because of decay, pain or impactions. The main reasons for tooth loss are decay or periodontal disease.
