The case of a 58-year-old white man with a history of high blood pressure and chronic obstructive pulmonary disease who developed double vision followed by right-sided facial paralysis is reported. A computerized axial tomogram (CT) scan showed an enhancing lesion in the pontine tegmentum, and the diagnoses of pontine glioma or hemorrhage were considered. Physical findings were limited to the cranial nerves. Conservative management with Decadron for 3 weeks resulted in a prompt clinical improvement, and a CT scan 1 month later showed resolution of the lesion, effectively ruling out a glioma. Total clinical recovery occurred at the end of 6 months. To our knowledge this is the first report of a case of Fisher one-and-a-half syndrome with facial paralysis correlated with computed tomography.

Ten patients from the Maine Medical Center with renal arterial injuries caused by blunt trauma are presented and analyzed along with 240 other case reports from the literature. Most patients were under 30 years of age and many were children. Injuries to the left side were more frequent; bilateral injuries occurred in 22 patients. Motor vehicle accidents were responsible for the majority of cases. Arterial thrombosis was the most common finding. Associated abdominal injuries were frequent, but the kidney itself was usually spared. Physical findings, urinalysis, and exploratory laparotomy were not reliable in the detection of arterial injury, but excretory urography and angiography were very accurate. Untreated unilateral injuries usually led to renal atrophy, but most did not cause hypertension; untreated bilateral injuries usually led to chronic renal failure or death. Few attempts at revascularization were successful. Excretory urography is recommended for all patients with blunt abdominal trauma; nonfunction should be investigated by angiography. Immediate bilateral repair is indicated in all cases of bilateral renal arterial injury, but repair of a unilateral injury is indicated only if it is promptly diagnosed in a young, stable patient.

Congenital renal arteriovenous malformations are rare, but their incidence are frequency of recognition are rising. Six cases of both cirsoid and idiopathic varieties are described. Patients were either asymptomatic or presented with gross hematuria and flank pain. Physical findings included hypertension, cardiomegaly, flank tenderness, and an abdominal bruit. IVP findings included filling defects in the renal pelvis from blood clots, irregular mucosal pattersn, or mass effect. Angiography demonstrated either single, simple, vascular channels or multiple, complex, varix-like communications. In both there was early filling of the renal vein, a normal caliber to the feeding artery and draining vein, and no displacement of parenchymal vessles. Asymptomatic patients required no treatment. Surgical procedures that spare renal parenchyma are preferred.

The diagnosis of preeclampsia is made on the basis of hypertension, proteinuria and edema. Unfortunately, all three of these findings can be seen in the patient who is experiencing a flare of systemic lupus erythematosus. The management of these conditions is entirely different. Preeclampsia frequently results in the need for delivery and occasionally, especially when remote from term, can result in significant neonatal morbidity and mortality. Systemic lupus may be treatable with a variety of pharmacologic agents. It is not always possible to make the distinction between active lupus and preeclampsia, and occasionally the two occur concurrently. Nevertheless, the goal of the rheumatologist and perinatologist is to try to make that distinction. Physical findings and serologic markers can be useful in helping to distinguish between these two diagnoses. Under certain circumstances, delivery is indicated despite the presence of continued uncertainty as to the actual diagnosis.

We report a case of preclinical Cushing's syndrome in a 54-year-old male associated with bilateral adrenocortical tumours. Physical findings and general laboratory data were unremarkable except for mild hypertension (158/90 mmHg) and impaired glucose tolerance. Endocrinological evaluation revealed the presence of autonomous cortisol secretion including unsuppressible serum cortisol by 8 mg dexamethasone test (11 microg/dl), high serum DHEA-S (3580 ng/ml, normal: 400-3500) and increased urinary 17-KS excretion (31.0-35.8 mg/day, normal: 5.8-21.3). CT scan demonstrated the presence of tumours in both adrenals and bilateral adrenalectomy was subsequently performed. Histological examination of the resected specimens revealed an adrenocortical carcinoma on the right side and an adenoma on the left side with noticeable cortical atrophy in non-neoplastic adrenals. Immunohistochemical study of steroidogenic enzymes demonstrated that all the steroidogenic enzymes involved in cortisol biosynthesis were expressed in both right and left adrenal tumours. Enzymatic activities of 21, 17alpha, 18, 11beta-hydroxylases were detected in both right and left adrenals except for the absence of 11beta-hydroxylase activity in the left adrenal adenoma. Results of in vitro tissue steroidogenesis examined in short-term tissue culture of the specimens revealed no significant differences between carcinoma and adenoma in cortisol production, but the production of adrenal androgens in carcinoma was significantly higher than that in adenoma, which may indicate the importance of evaluating adrenal androgen levels in patients with adrenocortical neoplasms.

The incidence of aortic dissection ranges from 5 to 30 cases per million people per year, depending on the prevalence of risk factors in the study population. Although the disease is uncommon, its outcome is frequently fatal, and many patients with aortic dissection die before presentation to the hospital or prior to diagnosis. While pain is the most common symptom of aortic dissection, more than one-third of patients may develop a myriad of symptoms secondary to the involvement of the organ systems. Physical findings may be absent or, if present, could be suggestive of a diverse range of other conditions. Keeping a high clinical index of suspicion is mandatory for the accurate and rapid diagnosis of aortic dissection. CT scanning, MRI, and transesophageal echocardiography are all fairly accurate modalities that are used to diagnose aortic dissection, but each is fraught with certain limitations. The choice of the diagnostic modality depends, to a great extent, on the availability and expertise at the given institution. The management of aortic dissection has consisted of aggressive antihypertensive treatment, when associated with systemic hypertension, and surgery. Recently, endovascular stent placement has been used for the treatment of aortic dissection in select patient populations, but the experience is limited. The technique could be an option for patients who are poor surgical candidates, or in whom the risk of complications is gravely high, especially so in the patients with distal dissections. The clinical, diagnostic, and management perspectives on aortic dissection and its variants, aortic intramural hematoma and atherosclerotic aortic ulcer, are reviewed.

Definition--signs and symptoms which include dispnea, hypertension, high temperature and high productive tracheobronchial secretion. Physical findings are lung oedema in first four hours. Such patients usually require respiratory help. After adequate therapy, symptoms disappeared in 96 hours. In the beginning. TRALI used to be a part of ARDS and it were treated that way. Today, TRALI is understand like substantive group of symptoms.

Peripheral vascular disease is a manifestation of systemic atherosclerosis that leads to significant narrowing of arteries distal to the arch of the aorta. The most common symptom of peripheral vascular disease is intermittent claudication. At other times, peripheral vascular disease leads to acute or critical limb ischemia. Intermittent claudication manifests as pain in the muscles of the legs with exercise; it is experienced by 2 percent of persons older than 65 years. Physical findings include abnormal pedal pulses, femoral artery bruit, delayed venous filling time, cool skin, and abnormal skin color. Most patients present with subtle findings and lack classic symptoms, which makes the diagnosis difficult. The standard office-based test to determine the presence of peripheral vascular disease is calculation of the ankle-brachial index. Magnetic resonance arteriography, duplex scanning, and hemodynamic localization are noninvasive methods for lesion localization and may be helpful when symptoms or findings do not correlate with the ankle-brachial index. Contrast arteriography is used for definitive localization before intervention. Treatment is divided into lifestyle, medical, and surgical therapies. Lifestyle therapies focus on exercise, smoking cessation, and dietary modification. Medical therapy is directed at reducing platelet aggregation. In addition, patients with contributing disorders such as hypertension, diabetes, and hyperlipidemia need to have these conditions managed as aggressively as possible. Surgical therapies include stents, arterectomies, angioplasty, and bypass surgery.

We reported a rare case of simultaneous primary aldosteronism and preclinical Cushing's syndrome due to unilateral double adrenocortical adenomas in a 57 year-old woman who had had hypertension for the last 10 years. Abdominal computed tomography showed double tumors in her right adrenal gland. Physical findings revealed simple obesity and hypertension, but no other abnormal findings were detected. Laboratory findings demonstrated that serum potassium was 3.8 mmol/l; plasma renin activity, 0.3 ng/ml/h; plasma aldosterone, 100 pg/ml, and aldosterone renin ratio (ARR), 33. Serum cortisol was 15.7 microg/dl. There was no circadian rhythm of serum cortisol, and no suppression of serum cortisol in response to exogenous dexamethasone administration. Right adrenalectomy was performed under laparoscopy. Two well-circumscribed tumors, whose sizes were 21 and 19 mm in greatest diameter, were detected. They were macroscopically composed of a golden-yellow portion admixed with a brown portion, which corresponded to clear cells and compact cells, respectively. Immunohistochemical staining for steroidogenic enzymes demonstrated the presence of all the enzymes involved in corticosteroidogenesis in these two adenomas, indicating that the two adenomas produced both cortisol and mineralocorticoid. Specifically, one adenoma mainly caused excessive production of cortisol as compared to the other one. These findings indicate that overproduction of both cortisol and mineralocorticoid was evident in the two adenomas of the right adrenal gland in immunohistochemical study for steroidogenic enzymes, whereas there was less clinical manifestation of primary aldosteronism and Cushing's syndrome in the present patient.

Portopulmonary hypertension (PPH) is clinically defined as the development of pulmonary arterial hypertension complicated by portal hypertension, with or without advanced hepatic disease. Physical signs may be absent in mild to moderate PPH and only appear in a hyperdynamic circulatory state. Similar signs of advanced liver disease can be observed in severe PPH, with ascites and lower extremity edema. Pulmonary hypertension is usually diagnosed after anesthetic induction during liver transplantation (LT). We present intraoperative pulmonary hypertension in a 41-year-old male patient with hepatic cirrhosis. Since this patient had no preoperation laboratory data supporting the diagnosis of pulmonary hypertension and was asymptomatic for a number of years, it was necessary to send him to the intensive care unit after operation. Further study should be focused on the diagnosis and treatment of pulmonary arterial hypertension in order to reduce its mortality.
