Description: Use warm water and sea salt. Soak the wart for 10 to 15 minutes in warm salt water to moisten the skin. Scrape the dead skin layers off the wart using a nail file, pumice stone or mild sandpaper. You could also use your fingers, but wash them thoroughly before and after, as warts can easily spread.

Transcript of the videos for you:
What we will be talking about to you today is post massive weight loss body contouring procedures. If you are someone who has lost a lot of weight or if you know someone who has lost a lot of weight, then this video is for you because I will be discussing in-depth about post massive weight loss body contouring.
Keep watching this video because this might benefit you and may change your life forever.
I am Dr. Rajat Gupta, a board-certified plastic surgeon working in Delhi, with an experience of over 2000 body contouring procedures.
So, letโ€™s talk about what is massive weight loss.
Now, any individual can lose a lot of weight. But massive weight loss means the loss of at least 10kg in 3 months time. So, lot of individuals lose a lot of weight either due to exercise, dieting or they undergo some procedures like bariatric surgery, in which there are different options of sleeve gastrectomy, roux en y bypass โ€“ all as simple as a balloon insertion into the stomach.
After all these interventions, a person loses a lot of weight and they reduce their subcutaneous fat a lot. Now, once they lose this weight and the subcutaneous fat what happens is that their skin starts sagging or the skin gets loose.
You may notice that they lose fat from their face and neck and the face and neck skin start loosening up. Or, majorly, they lose a lot of fat from their abdomen and their abdominal skin gets loose and it doesnโ€™t look nice if they remove their clothes. There is a huge amount of skin which is sagging. At the same time,
they may have some loose skin in their thigh area which does not look nice.
In females, once they lose a lot of fat, they may also get breast sagging. Their breasts may sag. Which also doesnโ€™t look nice. Depending upon what areas an individual has got sagging and in, we plan the correction for those areas. Basically, what they need is removal of excess skin.
Now, whether this excess skin is in their neck, in their chest, in their abdomen, in their arms or thighs, the treatment is customized depending upon what an individualโ€™s needs or requirements are. So, suppose someone has a lot of excess skin in their abdomen. What it needs is the removal of excess skin from the lower abdomen or a procedure known as tummy tuck or abdominoplasty. If a person has excess skin in their thighs or arms, then they need a reduction in their excess skin, in those areas and the procedure is called a thigh lift or an arm lift. For face and neck sagging, a person may undergo a procedure
called face or neck lift. And for the sagging of breasts, they need a procedure called breast lift or mastopexy.
Now, all these procedures are actually customized and tailored for each individual. But a person who has lost a large amount of weight and has sagging skin, they would eventually need this because sagging skin is
not only an aesthetic concern but that area is also very difficult to clean. The sweat gets accumulated, they may have some fungal infections there, and it doesnโ€™t look nice altogether. Iโ€™ve seen such individuals, when they remove their clothes, itโ€™s not only that they donโ€™t look nice, they also lose a lot of their confidence.
They display inhibitions even though they have lost such a large amount of weight and they look nice with clothes on. They would be inhibited by removing their clothes and going swimming or for a beach holiday.
So, understand that the ramifications of this procedure are not only for aesthetic concerns but also for the self-confidence of that person.
These procedures are reasonably safe procedures if done by a good plastic surgeon at a good center. Now, you need to choose your plastic surgeon keeping in mind a person who has experience with post massive weight loss contouring because these are some things which are very different to contour, the skin excess is in all dimensions, and therefore your plastic surgeon has to be smart enough and artistic enough that they understand how to remove the excess skin while giving you minimal scars and, at the same time,
enhancing the shape of your body.
Iโ€™ve tried to answer the indications of body contouring after post massive weight loss procedures. If you have any more questions regarding these procedures, please write into us and I will be there to help you. Thank you.

Acute sinusitis can be triggered by a cold or allergies and may resolve on its own. Chronic sinusitis lasts up to eight weeks and may be caused by an infection or growths. Symptoms include headache, facial pain, runny nose, and nasal congestion. Acute sinusitis usually doesn't require any treatment beyond symptomatic relief with pain medications, nasal decongestants, and nasal saline rinses. Chronic sinusitis may require antibiotics.

To record the sequence, Stephan Gordts and Ivo Brosens of the Leuven Institute for Fertility & Embryology in Belgium performed transvaginal laparoscopy, which involves making a small cut in the vaginal wall and observing the ovary with an endoscope.

"This allows us direct access to and observation of the tubo-ovarian structures without manipulation using forceps," says Gordts.

For the photos of ovulation, which only accidentally captured the critical moment, Jacques Donnez at the Catholic University of Louvain (UCL) in Brussels, Belgium, used gas to distend the organs for photography. However, Gordts and Brosens planned the procedure to coincide with ovulation and used saline solution to "float" the structures.
Perfect timing

Observation was timed for the day of the peak of the patient's luteal hormone cycle. Ovulation was predicted to occur on the evening of the day of the LH peak, and the endoscope introduced at 6 pm.

A small amount of saline was used to float the opening of the fallopian tube, its fimbriae (the "fingers" that sweep the egg into the tube) and the ovary itself. This gives a more natural appearance than gas, says Gordts.

In the video, the fimbriae can be seen sweeping in time with the patient's heartbeat. A mucus plug can be seen protruding from the ovary โ€“ this contains the egg.

"The ovum is not captured 'naked'," says Gordts. "There is no eruption like a volcano."

Gordts says that in clinical practice it is not easy to organise the observation of ovulation. "We were probably lucky to be successful at our first attempt," he says.

In this video, Professor Dan Reinstein performs a bilateral LASIK procedure filmed in real-time to demonstrate the full 8 and-a-half minute procedure from multiple angles. The superior design and experience of the Carl Zeiss Meditec Visumax femtosecond Laser for flap creation is seen, where the patient is only in contact with the device for about 30 seconds with extremely low contract force such that the patient feels effectively nothing, there are no red splodges (subconjunctival haemorages) left behind. From the surgeons' standpoint there is no device that is easier to use or faster for LASIK flap creation. The Carl Zeiss Meditec MEL80 excimer laser portion of the procedure is seamlessly integrated and incorporates all the features that make clinical outcomes so reproducible including the unique cone-for-controlled-atmosphere (CCA) and high efficiency, high sensitivity calibration test which can be performed for each individual patient to compensate for minor changes in energy that occur with excimer laser devices during the course of a day.

The typical radiograph is of a well-defined, rounded, retrocardiac opacity with an air-fluid level. In this image, the radiolucent gas is highlighted in blue, while the gastric contents are highlighted in the green. In many cases of hiatal hernia, there will not be an air bubble below the left hemidiaphragm. This is a relatively expected finding considering that the stomach is no longer in its usual position. The anatomical position of the herniated organ can be further elucidated on the lateral radiograph. Here we can see that the stomach is in the middle mediastinum posterior to the heart and above the diaphragm. Hiatal hernias can look similar to a retrocardiac lung abscess or another cavitary lesion, but it will change in size and shape between radiographs. Large hernias can shift the mediastinum to the right and result in a widening of the carinal angle. They can even give the appearance of cardiomegaly. In this radiograph, the cardiac silhouette is distinctly visible within the confines of the hiatal hernia. To review, a hiatal hernia on an AP chest radiograph typically appears as a round retrocardiac opacity with an air-fluid level.

Laparoscopy (from Ancient Greek ฮปฮฑฯ€ฮฌฯฮฑ (lapรกra) 'flank, side', and ฯƒฮบฮฟฯ€ฮญฯ‰ (skopรฉล) 'to see') is an operation performed in the abdomen or pelvis using small incisions (usually 0.5โ€“1.5 cm) with the aid of a camera. The laparoscope aids diagnosis or therapeutic interventions with a few small cuts in the abdomen.[1]

Laparoscopic surgery, also called minimally invasive procedure, bandaid surgery, or keyhole surgery, is a modern surgical technique. There are a number of advantages to the patient with laparoscopic surgery versus an exploratory laparotomy. These include reduced pain due to smaller incisions, reduced hemorrhaging, and shorter recovery time. The key element is the use of a laparoscope, a long fiber optic cable system that allows viewing of the affected area by snaking the cable from a more distant, but more easily accessible location.

Laparoscopic surgery includes operations within the abdominal or pelvic cavities, whereas keyhole surgery performed on the thoracic or chest cavity is called thoracoscopic surgery. Specific surgical instruments used in laparoscopic surgery include obstetrical forceps, scissors, probes, dissectors, hooks, and retractors. Laparoscopic and thoracoscopic surgery belong to the broader field of endoscopy. The first laparoscopic procedure was performed by German surgeon Georg Kelling in 1901. There are two types of laparoscope:[2]

A telescopic rod lens system, usually connected to a video camera (single-chip or three-chip)
A digital laparoscope where a miniature digital video camera is placed at the end of the laparoscope, eliminating the rod lens system

The mechanism mentioned in the second type is mainly used to improve the image quality of flexible endoscopes, replacing conventional fiberscopes. Nevertheless, laparoscopes are rigid endoscopes. Rigidity is required in clinical practice. The rod-lens-based laparoscopes dominate overwhelmingly in practice, due to their fine optical resolution (50 ยตm typically, dependent on the aperture size used in the objective lens), and the image quality can be better than that of the digital camera if necessary. The second type of laparoscope is very rare in the laparoscope market and in hospitals.[citation needed]

Also attached is a fiber optic cable system connected to a "cold" light source (halogen or xenon) to illuminate the operative field, which is inserted through a 5 mm or 10 mm cannula or trocar. The abdomen is usually insufflated with carbon dioxide gas. This elevates the abdominal wall above the internal organs to create a working and viewing space. CO2 is used because it is common to the human body and can be absorbed by tissue and removed by the respiratory system. It is also non-flammable, which is important because electrosurgical devices are commonly used in laparoscopic procedures.[3]
Procedures
Surgeons perform laparoscopic stomach surgery.
Patient position

During the laparoscopic procedure, the position of the patient is either in Trendelenburg position or in reverse Trendelenburg. These positions have an effect on cardiopulmonary function. In Trendelenburg's position, there is an increased preload due to an increase in the venous return from lower extremities. This position results in cephalic shifting of the viscera, which accentuates the pressure on the diaphragm. In the case of reverse Trendelenburg position, pulmonary function tends to improve as there is a caudal shifting of viscera, which improves tidal volume by a decrease in the pressure on the diaphragm. This position also decreases the preload on the heart and causes a decrease in the venous return leading to hypotension. The pooling of blood in the lower extremities increases the stasis and predisposes the patient to develop deep vein thrombosis (DVT).[4]
Gallbladder

Rather than a minimum 20 cm incision as in traditional (open) cholecystectomy, four incisions of 0.5โ€“1.0 cm, or more recently, a single incision of 1.5โ€“2.0 cm,[5] will be sufficient to perform a laparoscopic removal of a gallbladder. Since the gallbladder is similar to a small balloon that stores and releases bile, it can usually be removed from the abdomen by suctioning out the bile and then removing the deflated gallbladder through the 1 cm incision at the patient's navel. The length of postoperative stay in the hospital is minimal, and same-day discharges are possible in cases of early morning procedures.[citation needed]

Homanโ€™s sign test also called dorsiflexon sign test is a physical examination procedure that is used to test for Deep Vein Thrombosis (DVT). A positive Homanโ€™s sign in the presence of other clinical signs may be a quick indicator of DVT. Clinical evaluation alone cannot be relied on for patient management, but when carefully performed, it remains useful in determining the need for additional testing (like D-dimer test, ultrasonography, multidetector helical computed axial tomography (CT), and pulmonary angiography) [1][2].
