The origin of cold ing in America along with our aging population and therapy in medicine can be traced back 4,500 years as their propensity for these common lesions. The treat- Egyptians treated injuries and infammation with cold ment time is quite brief, which is convenient for practi- water. Although ice was the early cryogen, the birth of tioners and patients, causes minimal pain and no modern destructive surgery was founded using liquid bleeding or odor. Despite preliminary costs of cryosur- nitrogen, which readily induced subzero skin tempera- gical hardware and storage devices, liquid nitrogen is tures with a low boiling point of −196°C [1]. A variety of techniques are gen, surpassing historic cryogens including liquefed available to help the contemporary clinician apply air, solidifed carbon dioxide, and liquid oxygen. The open spray tech- ing the 1960s brought about the frst handheld liquid nique, the chamber technique, and the closed contact nitrogen cooled probe in 1967 and subsequently the or probe technique are all reliable. Some clinicians handheld spray device commonly used today, which apply liquid nitrogen by hand using one or more became commercially available in 1968 [2]. This technique is the most Liquid nitrogen is readily available in nearly any unreliable as much of the liquid nitrogen is lost into area with modest industry and advances in modern atmospheric nitrogen gas during transfer to the skin, holding tanks allow liquid nitrogen supplies to be main- resulting in unpredictable tissue freezing from an tained for months without reflling. Although the development and more widespread use of these sophis- cotton-tipped applicators do not offer a consistent ticated portable instruments, refnements in techniques freeze, use of forceps frozen in liquid nitrogen has of liquid nitrogen have made cryosurgery quite practi- been described to offer limited subzero temperature cal in clinical medicine as tissue destruction can be and may be more useful for benign entities in delicate more reliably controlled. As a practical note, a fne forceps can be sub- merged into liquid nitrogen to transfer cold to small skin tags or fne seborrheic keratoses on the eyelid.

In the chamber technique, seborrheic keratoses which are more likely to be treated the cryogen is released into a chamber which is applied with two freeze–thaw cycles at 10–15 s. The turbulent movement of rheic keratoses are a common complaint and can be a liquid nitrogen in the chamber lowers the temperature cosmetic priority for women who fnd their foundation of the cryogen, further magnifying its destructive capa- make-up clumps and draws attention at these sites. Therefore, this technique must be utilized care- These thicker lesions can be effectively treated in a fully and is generally limited to treating malignancy single treatment session, but there is risk for persistent and for palliative care. Probes are hypopigmentation is more commonly seen when best for treating lesions on a fat surface and care must freeze–thaw times pass 20–30 s.

Even when a patient is a candidate for photore- nodularis helicis, condyloma, ephileds, lentigo simplex, juvenation with laser or intense-pulsed light therapy, molluscum contagiosum, prurigo nodularis, rosacea, initial treatment of the thickest lesions will improve sebaceous hyperplasia, syringomas, venous lake, ver- the aesthetic result. Although of cryotherapy to thick seborrheic keratoses during many diagnoses are on this list, cryoablation is often not consultation when patients elect photorejuvenation indicated since other preferred therapies exist.

Neglect in this area will add insult to injury and secondary neuronal death will occur erectile dysfunction from smoking discount red viagra amex. The neurological examination of the head injured child differs a little from that done for non traumatic coma or other neurological disorder erectile dysfunction medications for sale proven 200 mg red viagra. This is the most important question of all and may well be the most difficult to answer erectile dysfunction oral medication 200 mg red viagra with visa. In those below that age, the motor and eye opening scales may be used (except that children below the age of 9 months cannot localize pain), but a modification of the verbal scale is needed. The response to pain should be examined both with a supraocular stimulus (forlocalization, flexion, and extension) and with nail bed pressure, for example with a pencil (for withdrawal). There may be a need for flexibility in terms of the overlap between the age groups. Thus, children of any age who are restless and talking unintelligibly have a verbal score of 2 and are therefore deeply unconscious; they are at high risk of further deterioration. The following exclusionary criteria may result in some over admissions but will almost completely safeguard against sending a potential moderate or severe head injury home too early. Motor Eye opening 6 Obeys commands Normal spontaneous movements 4 Spontaneous 5 Localises to supraocular pain (>9 3 To voice months) 2 To pain 4 Withdraws from nail bed pressure 1 None 3 Flexion to supraocular pain 2 Extension to supraocular pain 1 No response to supraocular pain Verbal 5 Orientated Alert, babbles, coos, words or sentences normal 4 Confused Less than usual ability, irritable cry 3 Inappropriate words Cries to pain 2 Incomprehensible sounds Moans to pain 1 No response to pain Fig. Orotracheal intubation is preferred as it is quicker and involves less manipulation of the neck. This route also avoids aggravating any anterior basilar skull fracture or introducing infection into the anterior cranial vault. In the initial stabilization, control of the airway - directed to opening–protecting, and maintaining the airway (to prevent hypoxia and the deleterious effects of hypercarbia) adequate oxygenation, and ventilation are the first priorities. Blood Pressure in Head Injury Hypotension is common and blood loss should never be attributed to the head injury alone. Rapid and aggressive treatment is needed to prevent secondary damage from hypoxic-ischemic injury. Hypertension as part of the Cushing’s triad- hypertension, bradycardia and hypoventilation; is more common. Nonglucose containing fluids should be used in the initial resuscitation and normal saline is the best choice. The importance of this cannot be overemphasized as is clear from a 1981 study in Lancet7where it showed that the outcome differences between hypotensive and normotensive patients was vastly different. If there was no hypotension or hypoxemia- 39% had poor outcome, if hypoxemic- 59 %, If hypotensive at presentation–75 % and if both hypotensive and hypoxemic were present then 100% had a poor outcome. If the child needs to have a study for any abdominal injury, it is usually wise to include a head scan even if there is no absolute indication. This may prevent a second visit to the scanner and if the child is to undergo surgery on any other part of the body, anaesthesia will prevent repeated neurological examinations for several hours. It gives no additional information besides a possible fracture and is best avoided. A negative ultrasound cranium in an infant may give a false sense of security as it will miss details. The threshold for ordering a scan is so low that it is not worth elaborating on the indications. A quick cross table lateral X-ray can help visualize at least the top 3 vertebrae and a complete series can be taken later. Basic equipment needed for cervical and back immobilization: • Hard board with side handles to be carried by 2 or more people • Broad straps with Velcro for binding at 5 places-forehead, chin, shoulder level, hips, thighs and legs. Run your fingers down each cervical spinous process and ask if there is any pain or tenderness. If the answer is no then ask the child to gently move the neck up and down and sideways on his/ her own volition. Other Associated Injuries During the process of placing the child on the spine board while log rolling, a person whose hands are free should quickly examine the back, thighs and legs for bruising, lacerations, crepitus and obvious fractures. Injures can be easily missed and out of sight is out of mind once the child is intubated and sedated. If there is gross contamination along a fluid pathway, such as with a comminuted fracture of the paranasal sinus resulting from acute trauma, antibiotic prophylaxis does have a role. Severe hypocapnia by causing severe constriction of cerebral vessels can cause unwarranted ischemia and further exarcerbate secondary neuronal damage.

Patients suffering from meralgia paresthetica exhibit tenderness over the lateral femoral cutaneous nerve at the origin of the inguinal ligament at the anterior-superior iliac spine as well as a positive Tinel sign over the lateral femoral cutaneous nerve as it passes beneath the inguinal ligament erectile dysfunction treatment maryland buy red viagra paypal. Careful sensory examination of the lateral thigh reveals a sensory deficit in the distribution of the lateral femoral cutaneous nerve with no motor deficit should be present (Fig erectile dysfunction in the military buy red viagra 200mg free shipping. The patient suffering from meralgia paresthetica will experience burning pain impotence problems buy red viagra with mastercard, paresthesias, and numbness that radiates into the lateral thigh and does not go below the knee. Electromyography can distinguish lateral femoral cutaneous nerve entrapment from lumbar plexopathy, lumbar radiculopathy, and diabetic polyneuropathy. Plain radiographs of the hip and pelvis are indicated in all patients who present with lateral femoral cutaneous neuralgia to rule out occult bony pathology. Magnetic resonance imaging of the lumbar spine and lumbar plexus and retroperitoneum is indicated if tumor, infection or retroperitoneal hematoma is suspected (Fig. Ultrasound-guided lateral femoral cutaneous nerve block is utilized as a diagnostic and therapeutic maneuver in the evaluation and treatment of pain thought to be mediated via the lateral femoral cutaneous nerve (Fig. Proper out of plane needle position for performing lateral femoral cutaneous nerve block. The anterior-superior iliac spine and inguinal ligament are identified by visual inspection and palpation (Fig. A linear high-frequency ultrasound transducer is placed in a plane perpendicular with the inguinal ligament with the superior aspect of the transducer lying over the anterior-superior iliac spine and the inferior aspect of the transducer pointed directly at the pubic symphysis and an ultrasound survey scan is obtained (Fig. The hyperechoic anterior-superior iliac spine and its acoustic shadow are identified (Fig. The ultrasound transducer is then slowly moved in a inferomedial direction along the course of the inguinal ligament until the hyperechoic honeycombed appearing lateral femoral cutaneous nerve appears lying beneath the fascia lata and on top of the sartorius muscle (Fig. Medial to the lateral femoral cutaneous nerve is the femoral nerve, artery, and vein which can be easily visualized with color Doppler (Fig. B: Oblique placement of the ultrasound transducer placed in a plane perpendicular with the inguinal ligament with the superior aspect of the transducer lying over the anterior-superior iliac spine and the inferior aspect of the transducer pointed directly at the pubic symphysis. Oblique ultrasound image demonstrating the hyperechoic anterior-superior iliac spine and its acoustic shadow and the inguinal ligament. Oblique ultrasound image demonstrating the hyperechoic honeycombed appearing lateral femoral cutaneous nerve appears lying beneath the fascia lata and on top of the sartorius muscle. Oblique color Doppler image demonstrating the femoral nerve artery and vein which lie medial to the lateral femoral cutaneous nerve. When these classic honeycombed, triangular, sonographic signature of the lateral femoral cutaneous nerve is identified on ultrasound scan, the nerve is evaluated for compression, enlargement, and tumor (Fig. The course of the nerve is traced both superiorly and inferiorly to identify abnormalities (Figs. Meralgia paresthetica caused by hip-huggers in a patient with aberrant course of the lateral femoral cutaneous nerve. Meralgia paresthetica caused by hip huggers in a patient with aberrant course of the lateral femoral cutaneous nerve. Therapeutic lateral femoral cutaneous nerve blocks with local anesthetic and steroid are extremely beneficial when treating meralgia paresthetica. However, if a patient presents with pain suggestive of meralgia paresthetica and lateral femoral cutaneous nerve blocks are ineffectual, a diagnosis of lesions more proximal in the lumbar plexus or L2-L3 radiculopathy should be considered. Electromyography and magnetic resonance imaging of the lumbar plexus are indicated in this patient population to help rule out other causes of lateral femoral cutaneous pain, including malignancy invading the lumbar plexus or epidural or vertebral metastatic disease at L2-L3. Meralgia paresthetica: a result of tight new trendy low cut trousers (‘taille basse’). The nerve fibers enter the psoas muscle where they fuse together within the muscle body and leave the medial border of the psoas at the brim of the pelvis (Fig. The nerve passes behind the common iliac arteries to run adjacent to the lateral wall of the pelvis where it joins the obturator artery and vein. Along with the obturator artery and vein, the obturator nerve enters the obturator canal to pass into the proximal thigh (Fig. At this point the obturator nerve divides into four branches: (1) an anterior branch which provides sensory innervation to the hip joint and motor branches to the superficial hip adductors; (2) a cutaneous branch which provides sensory innervation to the medial aspect of the distal thigh; (3) a posterior branch which provides motor innervation to the deep hip adductors; and (4) an articular branch to the posterior knee joint. At this point the obturator nerve divides into four branches: (1) an anterior branch which provides sensory innervation to the hip joint and motor branches to the superficial hip adductors; (2) a cutaneous branch which provides sensory innervation to the medial aspect of the distal thigh; (3) a posterior branch which provides motor innervation to the deep hip adductors; and (4) an articular branch to the posterior knee joint. The nerve may be compressed and entrapped by retroperitoneal and pelvic cysts, tumors, hematoma and callus formation from healing pelvic fractures as well as by implantable mesh and tapes used for surgical correction of urinary incontinence and uterine prolapse (Figs. The nerve may be injured by penetrating injuries as well as from pelvic fractures, tumor, crush injuries, mid forceps deliveries, and from surgical misadventures during groin, pelvic, and medial thigh surgeries.
