Jaundice is often noticed after biliary colic and occasionally in acute pancreatitis purchase paroxetine us symptoms ear infection. The whole abdomen from the nipples above down to the saphenous openings (thus the inguinal and femoral rings are exposed) must be exposed discount paroxetine 10 mg with amex symptoms 11 dpo. But if this examination be left for the last it may be missed and actual cause of acute abdomen may thus remain in the dark buy generic paroxetine on line medications and breastfeeding. Distension is central in case of small bowel obstruction whereas it is peripheral in large bowel obstruction order paroxetine 10mg mastercard treatment 34690 diagnosis. In volvulus of the sigmoid colon and caecum distension almost immediately appears. In second stage of peptic perforation slight distension may be evident, on the contrary in biliary colic, acute cholecystitis, acute appendicitis and renal colic the contour of the abdomen remains normal. Similarly localized limitation of respiratory movement occurs in localized irritation of the peritoneum from inflammation of underlying organs e. The forearm should be kept hori zontal along the level of the abdomen so that the fingers are placed flat on the abdominal wall. Rough palpation will lead to voluntary contraction of the abdominal muscles of the patient and this will definitely stand in the way of obtaining right information from palpation, (ii) The clinician must keep his hands warm before palpation of the abdomen. This can be elicited by gently picking up a fold of skin and lifting it off the abdomen or by simply scratching the abdominal wall with finger. If this hyperaesthesia disappears during the process of illness it indicates bursting of the gangrenous appendix. If this proves to be the site of maximum tenderness, it is certainly the site of diseased viscus. In acute cholecystitis, tenderness is present just below the tip of the 9th costal cartilage on the lateral margin of the right rectus. This point is situated at the junction of the lateral 1/3 and medial 2/3 of the right spino-umbilical line joining the right anterior superior iliac spine and umbilicus. In doubtful cases one can can be easily revealed by this the bed is moved slightly and this ^ • also on the left iliac fossa, it indicates spreading peritonitis and demands immediate surgical intervention. Very often a case of peptic perforation has been diagnosed as acute appendicitis due to presence of right iliac fossa tenderness. Appendicular tenderness can be best elicited in the left lateral position when the viscera shift to the left exposing the appendix to direct palpation. With each expiration the hand on the abdomen is gradually pressed down as the circumstances may allow. As a result of this abrupt removal the abdominal musculature springs back into its original place. This is due to the fact that the parietal peritoneum which has already been inflamed due to the presence of underlying inflamed organ also springs back along with the abdominal muscles. In presence of abdominal guarding due to generalized peritonitis this test may not be necessary. Presence of this sign in acute intestinal obstruction suggests strangulation of the gut. This is due to the fact that the coils of ileum shift slightly to the right and press on the inflamed appendix. This is a very important test to differentiate acute appendicitis from similar other abdominal conditions. The left iliac fossa is pressed and the pain is appreciated in the right iliac Fig. The right thigh is being hyperextended which will initiate pain in a case of retrocaecal appendicitis. When the right hip joint of the patient is hyperextended this muscle is stretched. The pelvic appendix may lie on the lower limb is being internally rotated which will stretch the obturator internus muscle. The patient is now asked to raise the right lower limb off the bed keeping the knee extended. The patient will immediately complain of pain in case of retrocaecal appendicitis. Retrocaecal appendix remains in close contact with the Psoas major muscle which becomes contracted during flexion of the hip joint. Here lies the importance of the above-mentioned tests which become positive in retrocaecal and pelvic appendicitis accordingly. This may be due to inflammation, presence of blood or contents of hollow organs within the peritoneal cavity. This is a part of the protective mechanism which is also seen in case of irritation of parietal pleura with restricted movement of the chest, irritation of the synovial membrane with restricted movement of the joint and irritation of the meninges in case of meningitis with rigidity of the neck. It is of utmost importance to differentiate voluntary from involuntary muscular rigidity. The hand in contact with the abdomen feels for muscular rigidity whereas the hand over it the clinician is very much looking for, applies pressure. During palpation the hand must be placed flat on the abdomen using flexor surfaces of the fingers as the palpating media and must not try to poke the fingers deep into the abdomen. Gentle movement of the straight fingers will be able to find out presence or absence of involuntary muscle guard. This should be carried out all through out the abdomen so as to detect localized muscle guard, if present. Another method of eliciting involuntary muscle guard is to use both hands during palpation one above the other. The hand in contact with the abdominal wall remains passive and wholly utilized to feel the condition of the abdominal musculature while the hand above is used to exert a slight and steady pressure to assist the hand below for better palpation. Unlike the involuntary muscle guard, the voluntary muscular rigidity will disappear during expiration and helps the clinician to palpate in a better way. Presence of a muscle guard over the upper half of the right rectus muscle in a patient who is seized with a sudden pain over the same region is strongly suggestive of perforation of a peptic ulcer and demands immediate surgical intervention. The Surgeon should not wait for board-like rigidity of the whole abdomen which is a late feature of this condition. In case of appendicitis the site of muscle guard varies according to the position of the appendix. In case of paracaecal appendix the rigidity will be present over the right iliac fossa, whereas in case of retrocaecal appendicitis it will be present over the loin and in the pelvic type there may not be any rigidity of the anterior abdominal wall. Muscle guard will be conspicuous by its absence in case of all colics due to absence of irritation of the parietal peritoneum. Similarly acute intestinal obstruction without strangulation will not show any rigidity of the abdomen. Differentiation of rigidity due to thoracic disease from that due to perforated peptic ulcer is made by asking the patient to take deep breath in and out with open mouth. During expiration the rigidity will be diminished in case of thoracic diseases whereas in case of peptic perforation it is always present. Generalized distension of the abdomen is a late feature of general peritonitis and the patient must not be allowed to reach that stage under any circumstances. Carefully palpate the lump noting its position, size, shape, consistency and mobility.
Interstitial lung disease with or without hilar adenopathy can also be a presentation of sarcoidosis discount paroxetine 10 mg amex symptoms norovirus. The definitive diagnosis of sarcoidosis rests on biopsy of suspected tissues order paroxetine toronto medications parkinsons disease, which show noncaseating granulomas discount 30 mg paroxetine xerostomia medications that cause. Eighty percent of patients with lung involvement from sarcoidosis remain stable paroxetine 40mg on-line medicine administration, or the sarcoidosis spontaneously resolves. Twenty percent of patients develop progressive disease with evidence of end-organ compromise. Generally in the setting of organ impairment, a trial of steroids may be used, giving a high dose for 2 months followed by tapering the dose over 3 months. Usually, pneumoconiosis appears 20–30 years after constant exposure to offending agents (metal mining of gold, silver, lead, copper), but it can develop in <10 years when dust exposure is extremely high. History is of primary importance in assessing possible occupational lung diseases. Alveolar macrophages engulf offending agents, causing inflammation and fibrosis of the lung parenchyma in pneumoconiosis. Signs and symptoms include dyspnea, shortness of breath, cough, sputum production, cor pulmonale, and clubbing. Asbestosis Asbestosis is an occupational lung disease caused by prolonged inhalation of asbestos dust. Asbestos fiber exposure may be seen in mining, milling, foundry work, shipyards, or the application of asbestos products to pipes, brake linings, insulation, and boilers. Signs and symptoms include exertional dyspnea and reduced exercise tolerance, cough and wheezing (especially among smokers), chest wall pain, and ultimately respiratory failure. On chest x-ray, diffuse or local pleural thickening, pleural plaques, and calcifications at the level of the diaphragm are seen. Pleural effusions are commonly seen, and the interstitial lung process associated with asbestosis usually involves the lower lung fields. The most common cancer associated with asbestosis is bronchogenic carcinoma (adenocarcinoma or squamous cell carcinoma). Pleural or peritoneal mesotheliomas are also associated with asbestos exposure but are not as common as bronchogenic cancer. For diagnosis, a lung biopsy is usually needed; the classic barbell-shaped asbestos fiber is found. Patients with asbestos exposure should strongly be advised to stop smoking since their risk of lung cancer is 75 times higher than that of the normal population. Silicosis Silicosis is an occupational lung disease caused by inhalation of silica dust. It is seen in individuals who work in mining, quarrying, tunneling, glass and pottery making, and sandblasting. Silicosis causes similar symptoms to asbestosis (or any other pneumoconiosis) except the acute form of silicosis, which is caused by massive exposure that causes lung failure in months. Silica causes inflammatory reactions with pathologic lesions being the hyaline nodule. In silicosis there are nodules (1–10 mm) seen throughout the lungs that are most prominent in the upper lobes. In progressive massive fibrosis, densities are 10 mm or more and coalesce in large masses. Patients clinically present as they would with any other occupational lung disease. On chest x-ray, small round densities are seen in the parenchyma, usually involving the upper half of the lungs. Complicated or progressive massive fibrosis is diagnosed by the presence of larger densities from 1 cm in diameter to the entire lobe. Clinical Recall A 65-year-old man complains of progressive difficulty breathing for the past 6 months. Thromboembolic disease is a common cause of morbidity and mortality in the hospital and outpatient setting and poses a diagnostic challenge even for seasoned clinicians. In one-third of the cases, they extend to the proximal veins and thus become a source of pulmonary emboli. Pulmonary embolism can infrequently occur with upper extremity, subclavian, and internal jugular vein thrombosis. Also, in the pregnant patient, thrombosis may occur initially in the pelvic veins rather than follow the usual course of starting in the distal and then extending to the proximal veins. Be concerned about (and treat) proximal vein thrombosis because this may result in pulmonary embolism. Unilateral Right Leg Swelling Due to Deep Venous Thrombosis Biomedical Communications 2007—Custom Medical Stock Photo. It usually breaks off into multiple thrombi as it goes into the pulmonary circulation, obstructing parts of the pulmonary artery. This results in increased alveolar dead space, vascular constriction, and increased resistance to blood flow. When ~50% of the lung vasculature is involved, significant pulmonary hypertension may occur. This is followed by an increase in right ventricular workload and may lead to right-sided heart failure. About 10% of patients with pulmonary embolus will die within 1 hour of the event, most from a massive pulmonary embolus or significant comorbid conditions (e. They are done routinely in the emergency department in the evaluation of patients with dyspnea. In ~10% of patients with documented pulmonary thromboembolism, the A-a gradient may be normal and the hypoxemia mild. Chest x-ray is very important in finding other causes that may account for the patient’s symptoms. The most common chest x-ray finding associated with pulmonary thromboembolism is a “normal” chest x-ray. Other nonspecific findings include atelectasis and pleural effusion (transudative and exudative). Westermark sign is the lack of vascular markings that occur distal to the pulmonary embolus. Specific tests are more specific for the evaluation of thromboembolic disease (do them when considering the diagnosis). It allows direct visualization of the pulmonary embolus, and it also allows for the diagnosis of alternative diseases involving the lung parenchyma (pneumonia, pneumothorax, etc. Ventilation-perfusion ( / ) scan is a pair of nuclear scan tests that use inhaled and injected material to measure breathing (ventilation) and circulation (perfusion) in all areas of the lung. A pulmonary embolus will typically cause perfusion defects with normal ventilation. The / scan, depending on the number of defects, is classified as normal, low probability, intermediate probability, or high probability. Pulmonary angiogram is the gold standard procedure for the diagnosis of pulmonary embolus.

Pitfalls and Danger Points Extent of Lymphadenectomy Impairing the viability of the skin ﬂaps Injuring the iliofemoral artery or vein Two lymph node groups are accessible and may be removed Injuring the femoral nerve and its branches during a groin dissection: inguinal and pelvic lymph nodes. The inguinal (or superﬁcial) nodes are located in the femoral triangle based on the inguinal ligament, with its apex formed by the crossing of the adductor longus and the sartorius muscles. The pelvic (or deep) component of the dissection includes the lymph nodes in a triangular area whose apex is formed by the bifurcation of the common iliac artery and whose base is essentially the fascia over the obturator foramen. Chassin generally begins with the superﬁcial component and then progresses more deeply. Exposing the Iliac Region When exposing the region of the iliac vessels for a pelvic lymphadenectomy, two approaches have commonly been employed. One involves vertical division of the inguinal ligament along the line of the iliofemoral vein with later resuturing of this ligament and the ﬂoor of the inguinal canal. Moreover, patients in whom this approach is employed appear to have an increased number of skin com- plications. An alternative approach to the pelvis for iliac lymphadenectomy is to place a second incision in the lower abdomen parallel to and about 3–4 cm cephalad to the ingui- nal ligament. After this incision has been carried through the transversalis fascia, the peritoneal sac is retracted upward to expose the iliac vessels and their adjacent fat and lymph nodes. Remember that it is not necessary to elevate • Transposition of sartorius muscle or not? The lateral boundary consists of the medial border of the sartorius muscle, and the lateral aspect of the adductor Operative Technique longus muscle is the medial boundary. The apex of the femo- ral triangle constitutes the point where the sartorius muscle Incision and Exposure meets the adductor longus. Dissecting the skin beyond the femoral triangle has no therapeutic value and may impair Position the lower extremity so the thigh is mildly abducted blood supply to the skin.

Continue along the Initiate the dissection along a line parallel and 5–6 cm cepha- inguinal crease in a medial direction until the femoral vein lad to the inguinal ligament. At this point curve the incision gently in a rosis of the external oblique muscle. In men, identify and preserve the spermatic trocautery with a low cutting current or a scalpel to dissect cord as it emerges from the external inguinal ring (Fig. In obese patients we overlying the adductor longus muscle just below the inguinal make the plane of dissection somewhat deeper than 4–5 mm.

Continue the dissection along this muscle in a cephalad margin of the dissection should be 5–6 cm above caudal direction to a point where the sartorius muscle crosses the inguinal ligament. Now dissect the inferior skin ﬂap in a the lateral margin of the adductor longus muscle. At the apex of the femoral triangle, identify, lymph node situated in this triangle, and label it for the pathol- ligate, and divide the internal saphenous vein. Continue to dissect the specimen laterally, exposing the the fascia overlying the sartorius muscle beginning at the length of the femoral artery. Several small arterial branches apex of the femoral triangle and continuing in a cephalad going to the specimen must be divided and ligated before the direction up to the origin of the sartorius muscle at the iliac specimen can be separated from this vessel. Sweep the fat, lymphatic tissue, and fascia overlying oral nerve, situated just lateral to the femoral artery, is covered the sartorius muscle by dissecting in a medial direction.
