Whether to use a gown A surgical gown is recommended generic 250mg ritonavir with amex medications on airplanes, though a circumcision operation may be performed with the surgeon wearing sterile operating gloves but without a sterile gown, or using full operating theatre gowning techniques. It is less expensive to use gloves only, and this is the practice in many clinic settings. The surgeon should, in any case, wear a clean theatre uniform, cap and theatre shoes. If a surgical gown is not used, it is important that the surgeon wears a clean apron to protect clothes from splashes during the operation. Face masks and protective eyewear Face masks are recommended, as they reduce droplet contamination if the surgeon coughs or sneezes, and protect the surgeon’s mouth from any spray of blood droplets. Eyewear is also recommended, and should be worn (together with a mask) whenever an accidental splash of blood onto the face is likely.

The penis is composed of two interconnected erectile bodies, the corpora cavernosa, which are attached and thus anchored to the underside of the front of the pubic bones. The wall of the erectile bodies is made of tough elastic tissue – the tunica albuginea. Surrounding the urethra is a quilt of erectile tissue, the corpus spongiosum, which continues and expands at the distal end of the penis to form the glans; this is like a helmet across the ends of the corpora cavernosa. The corpus spongiosum contributes to engorgement of the glans and to some expansion of the girth of the penis, but does not contribute significantly to its rigidity. In the malformation called hypospadias, it may emerge on the underside of the glans in the corona. Minor variations in the position of the urethral meatus are very common and do not require any treatment, provided that the man is able to pass urine freely and has a straight penile erection. The foreskin is the fold of skin that covers the glans when the penis is soft; during sexual intercourse, the foreskin is pulled back away from the glans. In the midline of the underside of the penis, there is a band of skin – the frenulum – which helps the foreskin to return to its usual position. Immediately underneath the frenulum is the frenular artery, which can cause troublesome bleeding during circumcision procedures. It is important to understand the relative positions of the urethra, the frenular artery and the frenulum, because the urethra can easily be injured during attempts to stop bleeding from the frenular artery. The urethra is also vulnerable to injury in babies, because the tissue between the frenulum and the urethra is very thin and delicate. The erectile bodies (corpora cavernosa), the urethra and its erectile tissue (corpus spongiosum) are in turn held together by a tough penile fascia (Buck’s fascia). The penis has a plentiful blood supply from the internal iliac arteries in the pelvis via the pudendal arteries. These in turn divide to give rise to the dorsal penile artery on each side and an artery in the centre of each erectile body. The dorsal penile nerves are located on the upper aspect of the penis, slightly to the side of the midline and deep to the penile fascia. At the base of the penis, these nerves are relatively compact but as they run towards the glans the nerve fibres fan out. This is why, in a penile block, most of the local anaesthetic is injected at the 1 o’clock and 11 o’clock positions at the base of the penis (see Chapter 5).

To avoid a risk of allergic-anaphylactoid reaction and/or thromboembolic events generic 250 mg ritonavir fast delivery symptoms you may be pregnant, which may be life threatening purchase ritonavir 250mg amex 6 mp treatment, no hemostatic agents should be injected into a vessel or directly into tissue buy ritonavir 250 mg with amex medications i can take while pregnant. As Tisseel Fibrin Sealant is made from 101 human plasma discount ritonavir 250mg on-line treatment jiggers, it may contain infectious agents, such as viruses. While fibrin glue products are commonly used for hemostasis, they are not as effective as other agents such as Floseal. Indeed, the comparative limited hemostatic ability of 65 fibrin glue products, and the lack of “sealant” capability, makes the applications of fibrin glue products in urology very limited. Floseal requires the presence of the patient‟s own fibrinogen from their own exposed blood to create a hemostatic coagulum. First, the collagen granules expand by hydration from blood and work into irregular surfaces such as the cut surface of the kidney to yield local micro-compression. This property helps to secure Floseal to vertical surfaces and prevent “run down”. Second, an absorbable bolster is placed over the Floseal and direct pressure or “macro-compression” is applied by the surgeon. Finally, the collagen beads of the Floseal are coated with thrombin which makes contact with and cleaves the fibrionogen in the pateint‟s own blood to create a bland fibrin clot. Floseal decreases hemorrhagic complications when 102 used during laparoscopic partial nephrectomy. CoSeal surgical sealant is a hemostatic substance, commercially available from Baxter pharmaceuticals, which form when two distinct polyethylene gycol polymers chemically bind together. When the polymers from two syringes are combined and applied to tissue, a synthetic hydrogel forms that provides hemostasis. However, the substance may adhere to tissues (other than those for which it is intended) or cause a local inflammatory response. As with any hemostatic agent, it should not be injected into a vessel 66 as it may cause thromboembolization. A recent porcine study, however, found that CoSeal was not as effective in adhering to the cut surface of the kidney as 103 Tisseel. Bioglue also covalently bonds the proteins within the tissue at the site where it is applied. This creates a mechanical seal that does not rely upon the patient‟s own clotting mechanisms. As with any hemostatic agent, it should not 104 be injected into a vessel as it may cause thromboembolization. Regarding hemostasis, BioGlue was originally designed for closure of small vascular defects suring anastomoses. Application for parenchymal bleeding such as with partial nephrectomy has not been verified. Similarly, there is no evidence that BioGlue is a sealant in the human urinary tract. Indeed in a recent porcine study, reinforcement of laparoscopically sutured vesicourethral anastomoses with Bioglue actually impaired wound healing on histological analysis when compared 105 with a laparoscopically sutured vesicourethral anastomosis alone. Surgicel 67 provides a surface on which the patient‟s own intrinsic clotting mechanisms act to from a clot. These products are produced from plant material so there is no risk of transmission of animal or human pathogens. To give extra volume and a larger bolster, these products can be wrapped around Gelfoam. Retractors Just as with open surgery, exposure is frequently the key to elegant and precise dissection. In laparoscopic surgery where the surgeon is limited to two working instruments (can not use the hand for multiple activities such as simultaneous retraction and dissection) the application of fixed retractors can be very important to optimize exposure and dissection. This combination can provide a safe and effective means of self-retaining retraction during laparoscopic surgery 68 Figure 14a 14b Fig 14c 14d the fixed retractor system has four components: a table attachment; a base rod with couplings; a flexible, spring-loaded articulating arm; and a precision clamp which can hold a variety of instruments. When used in over 200 cases, the only complication experienced was 107 a single minor liver laceration. Hand-assist devices Hand-assist devices allow the surgeon‟s hand access to the abdomen during hand-assisted laparoscopic surgery. One ring is placed within the abdominal incision, which is made wide enough to fit the surgeon‟s hand. The length of the incision should match the surgeon‟s glove size (A surgeon with a size eight glove should use an 8 cm incision). A larger incision may cause poor fitting of the device and leakage of the pneumoperitoneum. The other ring snaps onto the Gelport which uses a biocompatible gel as a valve mechanism to allow the hand and instruments in and out of the peritoneal cavity while still maintaining the pneumoperitoneum. The Gelport (Applied Medical, Rancho Santa Margarita, Calif) the LapDisc works similarly but, it uses three rings. The other two rings remain outside the abdominal cavity and, using a ratcheting mechanism, create a locking iris which can be opened and closed to seal around the surgeon‟s hand, instrumentation, or seal off completely. An evaluation of the two devices at Washington University found that both devices decreased blood flow to the surgeon‟s hand and caused 70 108 discomfort. However, the Gelport was associated with more hand pain and caused a greater reduction in blood flow.

Referred tests have a variety of turnaround times depending on referral lab and specialty. Defects of enzymes needed at various steps of heme synthesis result in distinct clinical syndromes known as porphyrias. These syndromes can be clinically classified into those predominantly involving the skin, those manifesting as disorders of the liver/nervous system, and a combination involving all 3 entities (see Image 1, or below). They invariably result in accumulation and increased excretion of porphyrins and their precursors. Some porphyrias have acute presentations (acute intermittent, variegate, hereditary coproporphyria), whereas others have a chronic, relatively stable presentation (congenital, erythropoietic). In some porphyria patients and families, however, these diagnostic tools can reveal simultaneous findings that are compatible with 2 different forms of porphyria, a phenomenon referred to as dual porphyria. Acute porphyrias the acute porphyrias are characterized by periodic acute attacks of neurovisceral symptoms and may stay occult for a long time. Four major disorders in this group are the Doss porphyria, acute intermittent porphyria, hereditary coproporphyria, and variegate porphyria. These porphyria syndromes are characterized by abdominal pain, neurologic deficits, psychiatric symptoms, and colored (red) urine. Chronic porphyrias the chronic porphyrias are dermatologic diseases that may or may not involve the liver and nervous system and do not present with acute attacks as described for the acute porphyrias above. These syndromes include congenital erythropoietic porphyria, erythropoietic porphyria, and porphyria cutanea tarda. Clinical manifestations Clinical manifestations depend on the step in which the enzymatic defect occurs. If the enzymatic defects are in the final steps, sunlight-induced cutaneous lesions (photosensitivity) due to porphyrin accumulation in the skin will develop. This can be precipitated by certain lipophilic drugs (see the Drugs to Avoid section), hypoglycemia ("the glucose effect"),11 and a deficiency of heme, the end-product of the heme pathway (see Image 3) that acts as a negative feedback mechanism in normal circumstances. It is characterized clinically by photosensitive skin disease and a propensity to acute neurovisceral crises. Variegate porphyria is found worldwide but has an exceptionally high frequency in South Africa. This causes the generation of free radicals and, thereby, photosensitivity of all tissues exposed to light. In the dark, several other toxic mechanisms have been described: deposition of protoporphyrin crystals in hepatocytes and bile canaliculi, interference with redox systems and, recently, formation of cytotoxic bile. Clinical manifestations of erythropoietic porphyria are photosensitivity, insignificant hematologic abnormalities, and liver disease. There are 3 types of porphyria cutanea tarda with typical skin manifestations; patients present with skin fragility, erosions, vesicles, bullae, and milia in sun-exposed areas of the skin. Sometimes, there is the presence of periorbital mottled hyperpigmentation and hypertrichosis, sclerodermoid changes, and ulceration. The abdominal pain is rarely accompanied by fever, leukocytosis, or peritoneal signs. The lifetime prevalence of acute intermittent porphyria-associated seizures has been reported as 2. Epileptic seizures among persons with acute intermittent porphyria are less common than has been previously described. Diagnostic difficulty may lead to underdiagnosis of patients who present with strictly psychiatric symptoms. This assumption is supported by a high prevalence of acute intermittent porphyria in psychiatric hospitals. Physical Examination • In acute porphyrias presenting as abdominal pain, attention should be paid to peritoneal signs. The presence of localized tenderness, rebound tenderness, vaginal discharge, cervical motion tenderness, and/or genitourinary bleeding should raise "red flags" even in patients known to carry a diagnosis of porphyria, and alternative diagnoses should be sought.
