A surgeon, who can correct deformity, scars and disfigurement caused by accidents, birth defects and treat diseases like skin cancer (melanoma), is called a plastic surgeon. A plastic surgeon also performs surgeries purely based on cosmetic purposes, e.g. rhinoplasty. The first plastic surgeon of the U.S. was Dr. John Peter Mettauer who performed his first surgery of cleft palate in the year 1827. Plastic surgeons perform various levels of surgeries on human body to beautify and restructure it. The main surgeries performed by plastic surgeons:
Reconstructive surgeries: The most common surgeries in the reconstructive section are breast reconstruction, palate surgery, cleft lip, surgery for patients suffering from burns called contracture surgery. Another technique called microsurgery is performed where tissue is transferred from one place to another where tissue is damaged and needs replacement.
Cosmetic surgery: The most famous and common surgery in the area of plastic surgery is cosmetic surgery and is performed purely from beautification point of view. Cosmetic surgery also known as aesthetic surgery is done just to enhance the beauty of any part and may possibly be a reconstructive surgery. The surgery improves the beauty or looks of any part of the body and is usually referred with the name of that particular part of the body. For e.g. Abdominoplasty (tummy tuck - reconstruction of the abdomen), Blepharoplasty (eyelid surgery) - application of permanent eyeliner or reshaping the eyelids.
Cosmesis: Another common procedure called as cosmesis is a blend of reconstructive plastic surgery and cosmetic plastic surgery. In the process of reconstructive surgery, cosmetic surgery techniques are utilized thus improving cosmesis.
In addition to these branches of plastic surgery, there are also surgeries such as craniofacial surgery - mainly dealing with pediatric deformities, maxillofacial surgery - improvement of the jaw and the face.

Achalasia is a neurological disorder of the esophagus and the muscles associated with it. Achalasia is a Greek term which means lack of relaxation. It involves the sphincter muscles of the esophageal region which help in the movement of food in the alimentary by esophageal peristalsis. The upper esophageal sphincter muscle measures about 3- 4 cm and is composed of striated muscles. The lower or the distal esophageal sphincter muscle is smooth. The esophagus is further comprised of circular and longitudinal muscles which help in the peristaltic movement. The muscles of the mesenteric plexus have a significant role in the occurrence of conditions such as achalasia. This is because of the association of the mesenteric plexus with intramural nerve innervations. Studies reveal that the damage of the mesenteric plexus is caused by the immune system.
Clinical manifestations of Achalasia
Classical symptoms associated with achalasia include dysphagia, regurgitation and respiratory complications. The lower esophageal sphincter muscles are impaired in this condition causing distended lower esophagus. In this region, the food is stuck as the muscles of the lower esophageal sphincter do not relax causing disturbance in the peristaltic movements of the esophagus. The patient experiences pain or spasms as a result of the cramped food in the esophagus. Often there is a tendency to vomit followed by heartburn and weakness.
Incidences of chest pain and breathing difficulties due to nocturnal choking are not uncommon. Histological examination of the esophagus reveals the decrease in myenteric neurons which are predominantly responsible for the relaxation of the lower esophageal sphincter muscles. Achalasia is categorized as primary, secondary and pseudoachlasia depending upon the etiology of the disease. The primary cause of achalasia can be hereditary or underlying autoimmune disease. The secondary cause is associated with preexisting infections such as chagas disease. It is usually associated with malignancy.
Diagnosis of Achalasia
Achalasia onset is generally asymptomatic and the severity increases after five years. Patients who are probable suspects of achalasia are diagnosed using radiologic, manometric and endoscopic methods. The manometric analysis determines the esophageal pressure of the lower origin. This enables the peristalsis and relaxation associated with the esophagus. It also indicates the functionality of smooth muscle contraction pertaining to the lower esophageal region. Radiological analysis indicates the abnormalities in structural arrangement of the esophagus. The bird beak appearance of the esophagus is the classical sign for the occurrence of achalasia. A normal chest X-ray does not identify the presence of achalasia, but it gives an anatomical description of the respective changes pertaining to esophagus such as widening of the mediastinum due to esophageal dilation and presence of gastric air bubble which occurs because of lack of relaxation in the lower esophagus.
Treatment of Achalasia
The restoration of the esophagus is difficult. However, many treatment options are available for achalasia. Use of nitrates and calcium blocking drugs help in the prevention of calcification of the esophagus. In some cases, balloon dilation of the lower esophagus is done. Although this method has a short time recovery there is always a risk of perforation during the procedure. Surgical methods such as thoracotomy and myotomy are considered. In addition to these treatment options, endoscopic administration of botulinum toxin has also become a possible option.
Ureteroscopy is a common urological procedure administered in patients having urinary tract and bladder related disorders. Ureteroscopy is recommended for patients having kidney stones. The movement of the renal stones is monitored by urologists. Ureteroscopy is a minimal invasive endoscopic procedure predominantly involving the urethra, upper urinary tract and the urinary bladder.
A flexible or rigid form of telescope is passed through the urethra in order to view the affected region. The procedure is performed under general or spinal anesthesia. The telescopic examination of the ureter and associated organs reveals the exact location of the stone and also other disorders of the system. Other diagnostic tests such as X-rays, CT scan, EKG along with laboratory parameters like urinalysis and complete blood count also help in the effective determination of the underlying condition. This technique is usually followed by the other associated procedures such as lithotripsy in which laser beams are administered to the affected region to dissolve the calculi(stone) or to clear urinary tract strictures. The entire procedure may last from 30 minutes to three hours and patients are advised to stay in the hospital for a day.
The urologist uses the uterescope to remove small kidney stones while larger stones need to be broken up before removal. A kidney stone that has escaped from the kidney and got stuck in the ureter can be pushed back into the kidney. Here it has to be broken into smaller pieces to aid removal. A stent is usually left in place to allow the kidneys to pass the urine to the bladder. This is kept for a few days in case there is swelling and subsequent difficulty in draining the kidney of the urine.
Complications and risk factors
Hematuria happens because of the insertion of the ureteroscope. It usually subsides within 3 days. Antimicrobial therapy is given if hematuria is followed by an infection. Other possible complications are:
Stent associated pain
Perforations caused because of stents
Lower back pain
Urethral stricture or perforation
