A cutaneous field, because it is a single block administered to the dorsal root of S2. A dermatome, because it is a single block administered to one dorsal root of S2 Answer: a. The perineum is supplied with innervation by the pudendal nerve, consisting of spinal cord levels S2-S4. An injection at the dorsal root of S2 would effectively block the dermatome for S2 but not the cutaneous field. This injection is not taking place at the dorsal root of a spinal cord nerve, but rather occurs in the periphery. The pudendal nerve contributes to the innervation of the perineum and consists of spinal cord levels S2-S4. The perineum is made up of mutltiple dermatomes based on the pattern of innervation. A study conducted by Columbia University suggested that midwives were able to attain a high level of intact perineums in specific patients in specific circumstances of at home births. Researchers reported only 8 of 1068 women experienced a 3rd degree perineal tear that extended through the external anal sphincter during a home birth. Although the enteric system does effect the internal anal sphincter, it has no effect on the external anal sphincter b. The parasympathetic nervous system affects the internal anal sphincter, not the external anal sphincter. The external anal sphincter is skeletal muscle and therefore under the control of the somatic nervous system. The sympathetic nervous system does not hold any control over the external or internal anal sphincters. The New England Journal of Medicine reported that 8 out of 10 forceps assisted vaginal deliveries result in damage to the anal sphincters of the mother. The study found that 7 out of the 10 forceps assisted deliveries resulted in damage to the internal anal sphincter. As a result, what action will these 7 patients struggle with during their recovery in the following weeks. The intern anal sphincter will need to close in order to perform its true function as a sphincter. By affecting the nervous supply to the internal anal sphincters, the sphincter will remain open and unable to sclose. Think carefully about the anatomical function of a sphincter and what actions are necessary for it to perform its natural function. The external anal sphincter is the muscle group responsible for passing a bowel movement "at a socially acceptable time. The external anal sphincter and the puborectalis muscle are responsible for terminating a bowel movement. Questions 12-13 consider a 24 year-old primigravida, para 0 (first time pregnancy, no previous live births) woman who is struggling with a vaginal delivery. The coccyx is a flexible structure, as is evdienced by its movement in defecation. The structure of the female pelvis is wider (from ischial tuberosity to ischial tuberosity) than it is longer (from sacral promonotory to pubic symphysis) and in most women the inferior pubic ramus is not a significant concern. The structure of the female pelvis is wider (from ischial tuberosity to ischial tuberosity) than it is longer (from sacral promonotory to pubic symphysis) so the ischial tuberosity is not a significant concern. The structure of the female pelvis is wider (from ischial tuberosity to ischial tuberosity) than it is longer (from sacral promonotory to pubic symphysis). A study conducted by surgeons in the Netherlands reported that 9 out of 243 women experienced a specifc abnormality due to a horizontal incision that would otherwise not exist if their physician performed the vertical incision. The lateral cutaneous nerve of the thigh courses laterally across the iliacus muscles toward the anterior superior iliac spines where it passes posterior to the inguinal ligament and enters the thigh. At the level of the incision, the external oblique muscle has transitioned into the aponeuoritc part of the external obique. Both the vertical and horizontal incision would be passing through aponeurotic tissue and would yield the same effect. The medial compartment of the thigh is innervated by the nerves originatig at spinal cord levels L2 and below.

Apical group: which drains all of the other groups, lies behind the clavicle at the apex of axilla. Clinical/surgical classification of axillary lymph nodes: o this surgical classification is used in axillary dissection. Level 1: any lymph node below pectoralis minor (first group involved in malignancy), account for 80% of lymph nodes. Aging: o Perimenopause: decrease in glandular tissue, loss of lobular and alveolar tissue. Typically, the asymmetry is more noticeable during puberty and eventually breast size evens out during development.

Still no role in screening even in the mammographically dense breast Developing role in monitoring neo-adjuvant therapy? Out of 543 probably benign lesions in 5514 screening mammograms, only 1 was malignant (0. For further evaluation of spontaneous nipple discharge a ductography can be performed. Ductography is useful in detecting the location of the lesion within the duct and the extent of involvement. Identify source of discharge and test for presence of blood in discharge Consider ductography Lab tests: thyroid, prolactin. If it accumulates again then aspirate again while reassuring the patient that itll resolve after lactation period. Imaging for questionable cysts o In young patients only U/S is performed show multiple cysts o In 40 and above patients both U/S and mammogram are performed to exclude any underlying malignant pathologies.

It can spread to other parts of the body through the lymphatic system and through the bloodstream. Infiltrating or invasive ductal carcinoma accounts for about 80 percent of all breast cancers. About 10 to 15 percent of invasive breast cancers are invasive lobular carcinomas. These are multicenteric, and they can appear in the other breast as well (bilateral). Medullary Carcinoma o this type of invasive breast cancer has a relatively well-defined distinct boundary between tumor tissue and normal breast tissue.

In practical terms, acute protein depletion is not clinically important as it is rare, while chronic deficiency is important. Serum proteins as shown in Table 10-6 are useful, especially albumin and transferrin (an iron-binding protein). Due to their very short half-lives, prealbumin and retinol binding protein (apart from their dependence on vitamin A status) may reflect more acute protein intake than risk of protein malnutrition (which is a process with an onset of period of 7 to 10 days (Ramsey et al. Hence, albumin and transferrin remain the best measures of protein malnutrition, but with all of the caveats listed in Table 10-6. In protein malnutrition, the skin becomes thinner and appears dull; the hair first does not grow, then it may fall out or show color changes (Pencharz, 1985). Over a longer period of time, assessment of changes in lean body mass reflects protein nutritional status. The clinical tools most available to assess lean mass are dual emission x-ray absorptiometry and bioelectrical impedance (Pencharz and Azcue, 1996). This section reviews some of the possible indicators used or proposed for use in analyses estimating human protein requirements. Factorial Method the factorial method is based on estimating the nitrogen (obligatory) losses that occur when a person is fed a diet that meets energy needs but is essentially protein free and, when appropriate, also relies on estimates of the amount of nitrogen that is accreted during periods of growth or lost to mothers during lactation. The major losses of nitrogen under most conditions are in urine and feces, but also include sweat and miscellaneous losses, such as nasal secretions, menstrual losses, or seminal fluid. This is where the factorial method has its greatest weakness, since the relationship between protein intake and nitrogen retention is somewhat curvilinear; the efficiency of nitrogen retention becomes less as the zero balance point is approached (Rand and Young, 1999; Young et al. Additionally, in order to utilize the factorial approach when determining the protein requirement for infants and children, their needs for protein accreted as a result of growth must be added to their maintenance needs. Nitrogen Balance Method this classical method has been viewed by many as theoretically the most satisfactory way of determining the protein requirement. Nitrogen balance is the difference between nitrogen intake and the amount excreted in urine, feces, skin, and miscellaneous losses. As discussed below, nitrogen balance remains the only method that has generated sufficient data for the determination of the total protein (nitrogen) requirement. It is assumed that when needs are met or exceeded adults come into nitrogen balance; when intakes are inadequate, negative nitrogen balance results. In determining total protein (nitrogen) needs, high-quality proteins are utilized as test proteins to prevent negative nitrogen balance resulting from the inadequate intake of a limiting indispensable amino acid. A significant literature exists regarding the methods and procedures to use in determining nitrogen balance amount (Manatt and Garcia, 1992; Rand et al. Limitations of the Method the nitrogen balance method does have substantial practical limitations and problems. First, the rate of urea turnover in adults is slow, so several days of adaptation are required for each level of dietary protein tested to attain a new steady state of nitrogen excretion (Meakins and Jackson, 1996; Rand et al. Second, the execution of accurate nitrogen balance measurements requires very careful attention to all the details of the procedures involved. Since it is easy to overestimate intake and underestimate excretion, falsely positive nitrogen balances may be obtained (Hegsted, 1976). Indeed, an overestimate of nitrogen balance seems consistent throughout the literature because there are many observations of quite considerable apparent retention of nitrogen in adults (Oddoye and Margen, 1979). A third limitation of the nitrogen balance method is that since the requirement is defined for the individual, and studies rarely provide exactly the amount of protein necessary to produce zero balance, individuals must be studied at several levels of protein intake in the region of the requirement so that estimates of individual requirements can be interpolated (Rand et al. Finally, dermal and miscellaneous losses of nitrogen must be included in the calculation. These are inordinately difficult to measure, and vary with the environmental conditions. In fact, the literature indicates marked (at least twofold) differences between studies (Calloway et al. The inclusion of dermal and miscellaneous nitrogen losses can have a significant effect on estimates of amino acid requirements via nitrogen balance, especially in adults (Calloway et al. Statistical Analysis of Nitrogen Balance Data In studies with healthy adults in presumably good nutritional status, it is generally assumed that the protein requirement is achieved when an individual is in zero nitrogen balance.
