Presacral myelolipomas classically occur in older patients, with a female predominance of approximately 2:1 (4). Usually, they are asymptomatic and incidentally discovered; however, they may cause symptoms from mass effect on adjacent structures, including the bladder, ureters, sacral nerve plexus, and rectum (2,4,5). They are not associated with hematologic disturbances; however, they have been associated with Cushing syndrome, Addison disease, adrenal hyperplasia, and chronic exogenous steroid use (4). Presacral myelolipomas are typically well-encapsulated...

Gynecologic Pelvic Mass: Large uterine fibroid. Ovarian mass. Coelomic epithelial tumors: These tumors, which originate from the coelomic epithelium, constitute 80-85% of all ovarian tumors. Serous cystadenoma and mucinous cystadenoma: Fifteen to 20% are malignant. Endometrioid type and clear cell: Ninety-five to 98% are malignant. Brenner tumor: Two percent are malignant. Germ cell tumors: These tumors originate from the germ cell and constitute 10-15% of all ovarian tumors. All are malignant except mature teratomas and gonadoblastomas, which...
Meigs syndrome:
Posted on 15:03 by Unknown
Meigs syndrome: Meigs syndrome is defined as the triad of benign ovarian tumor with ascites and pleural effusion that resolves after resection of the tumor. The ovarian tumor in Meigs syndrome is a fibroma. Pseudo-Meigs syndrome consists of pleural effusion, ascites, and benign tumors of the ovary other than fibromas. These benign tumors include those of the fallopian tube or uterus and mature teratomas, struma ovarii, and ovarian leiomyomas. Pseudo-pseudo Meigs syndrome includes patients with systemic lupus erythematosus and enlarged ovaries....

Extrahepatic biliary atresia: Extrahepatic biliary atresia is obliteration or discontinuity of the bile ducts, usually in the region of the porta (i.e., hepatic or common bile ducts). Usually acquired postnatally at approximately 2 – 8 weeks of age. Progressive inflammation of biliary system associated with infections such as CMV, EBV, reovirus, rotavirus. Less often congenital and seen with other anomalies such as asplenia or situs inversus. Cholestasis leads to jaundice in baby several weeks old. Differential at this age is neonatal hepatitis...

Thoracic outlet syndrome:
Posted on 14:07 by Unknown
Thoracic outlet syndrome is a clinical constellation of symptoms secondary to neurovascular compression at the level of the thoracic outlet. These symptoms are often exacerbated by abduction of the arms. Patients may complain of worsened symptoms when their arms are raised. Neurologic symptoms can include pain, numbness, paresthesias, or weakness, usually in a radicular pattern. C8 and T1 are most commonly involved. Vascular symptoms can include pain, no pulse, and pallor. Physical examination maneuvers to elicit thoracic outlet syndrome include...

Progression of Mild Cognitive Impairment Visualized on PET
Posted on 19:32 by Unknown
Progression of Mild Cognitive Impairment Visualized on PETThe use of molecular imagining might help clinicians monitor the progression of mild cognitive impairment (MCI) and help to identify people at risk for Alzheimer's disease (AD), according to a study presented here at the Society of Nuclear Medicine 2008 Annual Meeting. "We can now visualize in vivo changes in the brain that correlate with clinical testing. Not all patients with MCI progress to AD. We think we will eventually be able to determine which persons will," Chester Mathis, PhD,...
Dermoid and Epidermoid, Oral Cavity
Posted on 17:25 by Unknown
Dermoids and epidermoids are cystic oral cavity lesions arising from congenital epithelial inclusions or rests. Dermoids and epidermoids most commonly involve the floor of mouth in the submandibular space (SMS), sublingual space (SLS) or root of tongue (ROT). Epidermoid and dermoid cysts are benign lesions encountered throughout the body, with 7% occurring in the head and neck area. The orbit is the most common site in the head and neck for these congenital lesions. They rarely occur within the oral cavity, representing less than 0.01% of all...

Preventing Contrast Induced NephropathyMichael SmithOverviewContrast induced nephropathy (CIN) is a serious concern for today’s emergency physician when ordering contrast enhanced imaging. CIN is usually defined by an increase in serum creatinine by 0.5 mg/dL or 25% from baseline that usually occurs 2-3 days after contrast administration.[1] The incidence of CIN is estimated to be 1-2% in the general population, but the relative risk is greatly increased in diabetics, the elderly, and those with intrinsic renal disease, congestive heart failure,...
