Most people develop several moles (nevi) throughout adulthood. Moles can be found anywhere on the body, usually in sun-exposed areas, and are usually brown, smooth, and slightly raised. In most cases, a nevus is benign and doesn't require treatment. Rarely, they turn into melanoma or other skin cancers. A nevus that changes shape, grows bigger, or darkens should be evaluated for removal.

Phacolytic glaucoma usually is associated with a mature or hypermature cataract and typically occurs in elderly patients. Today, phacolytic glaucoma is rare in the United States, found primarily in areas where access to care is poor. Will the increase in the number of under- and uninsured patients lead to an increase in this condition? Evaluation and Diagnosis Signs and symptoms. Patients typically report acute-onset pain, decreased vision, tearing and photophobia. Examination will reveal injection, corneal edema, elevated IOP, anterior chamber reaction with or without pseudohypopyon, particles on the lens capsule and anterior capsule wrinkling. Patient history. The duration of symptoms should be elicited; a delayed presentation of more than five days since onset can result in glaucomatous disc damage and poorer prognosis.¹ The ocular history may reveal that the patient decided against removal of an advanced cataract. Prior intraocular surgery or trauma may have left residual lens material that could cause phacoanaphylactic glaucoma or exacerbate infectious endophthalmitis. Visual acuity and visual potential should be assessed. Exam essentials. A complete ophthalmologic examination should be done. The eye should be inflamed, and the cornea may be edematous due to the high IOP. The anterior chamber will demonstrate massive inflammation and/ or pseudohypopyon. Gonioscopy is essential; it will help rule out angle closure due to phacomorphic glaucoma or neovascularization of the angle. Assess ment of the posterior pole should be performed to rule out vitreous hemorrhage (which can result in ghost-cell glaucoma) or vitritis (which may be associated with infectious endophthalmitis or panuveitis). If the view to the fundus is obstructed, B-scan ultrasonography also should be performed. Differential diagnosis. The differential diagnosis includes infectious endophthalmitis, phacoanaphylactic glaucoma, inflammatory glaucoma, glaucoma secondary to intraocular tumor, phacomorphic glaucoma, acute-angle closure glaucoma and neovascular glaucoma. Management Medication. Medical management is used to temporarily control the glaucoma and inflammation. Initial treatment consists of hyperosmotic agents, aqueous suppressants, anti-inflammatory drugs and cycloplegics. Surgery. Definitive treatment is removal of the lens via extracapsular cataract extraction with or without an IOL. Some ophthalmologists defer placement of an IOL until after the inflammation subsides; however, there is no significant difference in final visual acuity between those patients who did receive an IOL and those who did not.¹ If the phacolytic glaucoma is of long duration (more than seven days), a combined trabeculectomy may be needed to prevent postoperative IOP spikes.² In eyes with hypermature Morgagnian cataracts, one must be especially careful, as the capsule is fragile, the zonules are weak and the view is difficult due to the white, milky cortex. Vision limited to light perception on presentation is not a contraindication to performing cataract extraction. Surgical Tips For a planned extracapsular cataract extraction with a posterior chamber IOL, fashion a superior fornix-based conjunctival flap.³ Make a partial-thickness incision along the sclerolimbal junction superiorly for 120 degrees with a No. 69 blade. Forty-five degrees away, a paracentesis should be done to decompress the eye. The anterior chamber fluid can be withdrawn for analysis, to look for macrophages and high molecular-weight proteins. Inject balanced salt solution in a cannula to wash out any residual particulate matter, then inject Healon or viscoelastic into the anterior chamber. Make an incision entering the anterior chamber at the 12 o’clock position with a keratome. A 26-gauge cystotome mounted on a syringe is then introduced through the 12 o’clock incision and used to puncture the capsular bag. The milky cortex should be aspirated as much as possible, until the nucleus is visible. Withdraw the needle through the keratome incision, then inject Healon through the 12 o’clock incision into the capsular bag. Next, enlarge the corneoscleral keratome incision with curved Westcott scissors to 120 degrees. Perform a partial V-shaped capsulotomy; this can be done either with the cystotome or with an angled Vannas scissors. Place viscoelastic under the nucleus to float the nucleus and sever any adhesions between the nucleus and the capsule. The nuclear portion of the lens can then be removed with an irrigating vectis (lens loop) with or without gentle pressure at the inferior limbus (6 o’clock). Irrigate and aspirate the residual cortex with the Simcoe cannula. Inspect the capsular bag; if it is intact, place a posterior chamber IOL into the bag. Close the incision with several interrupted 10-0 monofilament nylon sutures and reattach the conjunctival flap. Potential Sequelae and Prognosis Postoperatively, the patient should be managed with topical steroids and/or aqueous suppressants and hyperosmotics if necessary. Vitreous opacification behind the posterior capsule occurs in a small percentage of eyes. These vitreous opacities are typically absorbed by one to two weeks postoperatively. IOP usually is controlled without antiglaucoma medications after the cataract removal. A detailed glaucoma evaluation (including repeat gonioscopy to assess for peripheral anterior synechiae, visual field and optic nerve status) should be done to assess the extent of glaucomatous damage. The prognosis is dependent on the duration of elevated IOP, PAS and optic nerve damage. In one study, patients who were older than 60 and whose glaucoma was present for more than five days did significantly worse than a comparison group of younger individuals with shorter disease duration.

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).

Stapling is used to treat prolapsed hemorrhoids. A surgical staple fixes the prolapsed hemorrhoid back into place inside your rectum and cuts off the blood supply so that the tissue will shrink and be reabsorbed. Stapling recovery takes less time and is less painful than recovery from a hemorrhoidectomy.

What Is a Hair Transplant? It's a type of surgery that moves hair you already have to fill an area with thin or no hair. Doctors have been doing these transplants in the U.S. since the 1950s, but techniques have changed a lot in recent years. You usually have the procedure in the doctor's office. First, the surgeon cleans your scalp and injects medicine to numb the back of your head. Your doctor will choose one of two methods for the transplant: follicular unit strip surgery (FUSS) or follicular unit extraction (FUE). With FUSS, the surgeon removes a 6- to 10-inch strip of skin from the back of your head. He sets it aside and sews the scalp closed. This area is immediately hidden by the hair around it. Next, the surgeon’s team divides the strip of removed scalp into 500 to 2,000 tiny grafts, each with an individual hair or just a few hairs. The number and type of graft you get depends on your hair type, quality, color, and the size of the area where you’re getting the transplant. If you’re getting the FUE procedure, the surgeon’s team will shave the back of your scalp. Then, the doctor will remove hair follicles one by one from there. The area heals with small dots, which your existing hair will cover. After that point, both procedures are the same. After he prepares the grafts, the surgeon cleans and numbs the area where the hair will go, creates holes or slits with a scalpel or needle, and delicately places each graft in one of the holes. He’ll probably get help from other team members to plant the grafts, too. Depending on the size of the transplant you’re getting, the process will take about 4 to 8 hours. You might need another procedure later on if you continue to lose hair or decide you want thicker hair. Expectations and Recovery After the surgery, your scalp may be very tender. You may need to take pain medications for several days. Your surgeon will have you wear bandages over your scalp for at least a day or two. He may also prescribe an antibiotic or an anti-inflammatory drug for you to take for several days. Most people are able to return to work 2 to 5 days after the operation. Within 2 to 3 weeks after surgery, the transplanted hair will fall out, but you should start to notice new growth within a few months. Most people will see 60% of new hair growth after 6 to 9 months. Some surgeons prescribe the hair-growing drug minoxidil (Rogaine) to improve hair growth after transplantation, but it’s not clear how well it works. Risks and Costs of Treatment The price of a hair transplant will depend largely on the amount of hair you’re moving, but it generally ranges from $4,000 to $15,000. Most insurance plans don’t cover it.
