ow does a perforation of the eardrum occur? There are many ways an eardrum perforation can occur. An infection behind the eardrum in the middle ear may cause a rupture of the eardrum. Trauma to the ear may result from an object entering the ear canal and puncturing the eardrum. A traumatic blow to the ear with a cupped hand can rupture the eardrum. Hot welding slag can burn a hole through the eardrum. After a ventilation tube has been extruded or is removed, the opening usually closes; in some cases a permanent opening of the eardrum may occur. Chronic ear problems such as deep retraction pockets and cholesteatoma​​ can weaken and erode the eardrum, resulting in a defect or perforation.

Overview HIV is a virus that affects the immune system, specifically the CD4 cells. The CD4 cells help protect the body from illness. Unlike other viruses that the immune system can fight off, HIV can’t be eliminated by the immune system. The symptoms of HIV can vary greatly from person to person. No two people with HIV will likely experience the exact same symptoms. However, HIV will generally follow this pattern: acute illness asymptomatic period advanced infection Acute illness Approximately 80 percent of people who contract HIV experience flu-like symptoms within two to four weeks. This flu-like illness is known as acute HIV infection. Acute HIV infection is the primary stage of HIV and lasts until the body has created antibodies against the virus. The most common symptoms of this stage of HIV include: body rash fever sore throat severe headaches Less common symptoms may include: fatigue swollen lymph nodes ulcers in the mouth or on the genitals muscle aches joint pain nausea and vomiting night sweats Symptoms typically last one to two weeks. Anyone who has these symptoms and thinks they may have contracted HIV should consider scheduling an appointment with their healthcare provider to get tested. Symptoms specific to men Symptoms of HIV are generally the same in women and men. One HIV symptom that is unique to men is an ulcer on the penis. HIV may lead to hypogonadism, or poor production of sex hormones, in either sex. However, hypogonadism’s effects on men are easier to observe than its effects on women. Symptoms of low testosterone, one aspect of hypogonadism, can include erectile dysfunction (ED).

Not every woman undergoes a traditional vaginal delivery with the birth of her child. Under conditions of fetal or maternal distress, or in the case of breech presentation (when a baby is turned feet first at the time of delivery), or if the woman’s first baby was born by cesarean delivery, a procedure called a cesarean section may be required. During a cesarean, a doctor will make either a lateral incision in the skin just above the pubic hair line, or a vertical incision below the navel. As the incision is made, blood vessels are cauterized to slow bleeding. After cutting through the skin, fat, and muscle of the abdomen, the membrane that covers the internal organs is opened, exposing the bladder and uterus. At this time the physician will generally insert his or her hands into the pelvis in order to determine the position of the baby and the placenta. Next, an incision is made into the uterus and any remaining fluids are suctioned from the uterus. The doctor then enlarges the incision with his or her fingers. The baby’s head is then grasped and gently pulled with the rest of its body from the mother’s uterus. Finally, the abdominal layers are sewn together in the reverse order that they were cut. The mother is allowed to recover for approximately three to five days in the hospital. She will also be quite sore and restricted from activity for the following several weeks. There are several potential complications associated with this procedure that should be discussed with a doctor prior to surgery.

A Pap smear (Papanicolau smear; also known as the Pap test) is a screening test for cervical cancer. The test itself involves collection of a sample of cells from a woman's cervix (the end of the uterus that extends into the vagina) during a routine pelvic exam

Your baby's sex is set at conception. At around 7 weeks, your baby's internal sex organs – such as ovaries and testes – begin to form in the abdomen. Male and female sex organs and genitalia look the same at this stage because they're derived from the same structures. At around 9 weeks, boys and girls begin to develop differently. In girls, a tiny bud emerges between the tissue of the legs. This bud will become the clitoris. The membrane that forms a groove below the bud separates to become the labia minora and the vaginal opening. By 22 weeks, the ovaries are completely formed and move from the abdomen to the pelvis. They already contain a lifetime supply of 6 million eggs. In boys, the bud develops into the penis and starts to elongate at around 12 weeks. The outer membrane grows into the scrotal sac that will later house the testicles. By 22 weeks, the testes have formed in the abdomen. They already contain immature sperm. Soon they'll begin their descent to the scrotum, but it's a long journey. They'll reach their destination late in pregnancy, or for some boys, after birth. If you're eager to find out whether you're having a girl or a boy, you'll have to wait until you're at least 17 weeks pregnant. That's when the genitals have developed enough to be seen on an ultrasound.

This is a diabetic foot ulcer. The patient reportedly went on vacation and noticed this ulcer upon their return. Debridement (removal of damaged tissue) to the level of healthy bleeding tissue is medically necessary as damaged tissue acts an impediment to wound healing. Due to their diabetic neuropathy, they did not feel any pain or indication that a wound was forming. This ulcer appeared to have penetrated to the level of subcutaneous tissue or even fascia, but turned out to be much deeper than that. These are serious wounds and are the beginnings of what lead to foot and leg amputations if they are not treated promptly by your healthcare provider, AKA Podiatrist.
