Glomus tumors are rare soft tissue neoplasms that typically present in adults (ages 20-40 years) as small, blue-red papules or nodules of the distal extremities, with most cases involving subungual sites. These tumors are typically painful, often causing paroxysmal pain in response to temperature changes or pressure. Glomus tumors are thought to arise from the glomus body, a thermoregulatory shunt concentrated in the fingers and toes. Most lesions are solitary and localized to cutaneous sites; however, generalized glomuvenous malformations, or multiple glomangiomas, have also been described, and may have extracutaneous involvement.
An abscess is an infectious process characterized by a collection of pus surrounded by inflamed tissue. [1, 2] Abscesses can form anywhere in the body, from a superficial skin (subcutaneous) abscess to deep abscesses in muscle, organs, or body cavities. Patients with subcutaneous skin abscesses present clinically as a firm, localized, painful, erythematous swelling that becomes fluctuant (see the image below).
The drugs known as targeted therapy help stop cancer from growing and spreading. They work by targeting specific genes or proteins. These genes and proteins are found in cancer cells or in cells related to cancer growth, like blood vessel cells. Doctors often use targeted therapy with chemotherapy and other treatments.
A prenatal ultrasound (also called a sonogram) is a noninvasive diagnostic test that uses sound waves to create a visual image of your baby, placenta, and uterus, as well as other pelvic organs. It allows your healthcare practitioner to gather valuable information about the progress of your pregnancy and your baby's health. During the test, an ultrasound technician (sonographer) transmits high-frequency sound waves through your uterus that bounce off your baby. A computer then translates the echoing sounds into video images that reveal your baby's shape, position, and movements. (Ultrasound waves are also used in the handheld instrument called a Doppler that your practitioner uses during your prenatal visits to listen to your baby's heartbeat.) You may have an early ultrasound at your practitioner's office at 6 to 10 weeks to confirm and date the pregnancy. Or you may not have one until the standard midpregnancy ultrasound between 16 and 20 weeks. That's when you may learn your baby's sex, if you like. (The technician will probably present you with a grainy printout of the sonogram as a keepsake.) You may also have a sonogram as part of a genetic test, such as the nuchal translucency test, chorionic villus sampling, or amniocentesis, or at any other time if there are signs of a problem with your baby. You'll have more frequent ultrasounds if you have diabetes, hypertension, or other medical complications.
Start in RLQ (so you don’t miss a giant spleen). Get your fingers set then ask patient to take a deep breath. Don’t dip your fingers or do anything but wait. When patient expires, take up new position. Note lowest point of spleen below costal margin, texture of splenic contour, and tenderness If spleen is not felt, repeat with pt lying on right side. Gravity may bring spleen within reach. “LET THE SPLEEN PALPATE YOUR FINGERS AND NOT THE OTHER WAY AROUND. THERE IS NO GOLD, SO DON’T DIG!”
The most common symptoms of pneumoconiosis are cough and shortness of breath. The risk is generally higher when people have been exposed to mineral dusts in high concentrations and/or for long periods of time. Inadequate or inconsistent use of personal protective equipment (PPE) such as respirators (specially fitted protective masks) is another risk factor since preventing dusts from being inhaled will also prevent pneumoconiosis. Pneumoconiosis does not generally occur from environmental (non-workplace) exposures since dust levels in the environment are much lower.
Hepatitis D, also known as the delta virus, is an infection that causes the liver to become inflamed. This swelling can impair liver function and cause long-term liver problems, including liver scarring and cancer. The condition is caused by the hepatitis D virus (HDV). This virus is rare in the United States, but it’s fairly common in the following regions: South America West Africa Russia Pacific islands Central Asia the Mediterranean
A diagnosis of sarcoidosis is established on the basis of compatible clinical and radiologic findings and histologic evidence of the presence of noncaseous epithelioid cell granulomas in one or more organs and the absence of causative organisms or particulates (16). Granulomas of known causes and local sarcoidlike reactions must be excluded. Granulomatous lesions may result from many conditions, including tuberculosis, berylliosis, leprosy, hypersensitivity pneumonitis, Crohn disease, primary biliary cirrhosis, and fungal disease. Moreover, local sarcoidlike reactions may be seen in lymph nodes that drain a neoplasm or a site of chronic inflammation (19). Such reactions also have been seen in patients who have undergone chemotherapy and radiation therapy (23). If biopsy of lymph nodes or pulmonary or pleural tissue is necessary for diagnosis, one of three techniques may be used: transbronchial biopsy, CT-guided biopsy, or surgical biopsy (24). The use of a surgical technique may be warranted when the results of biopsy with another procedure are not definitive and biopsy of mediastinal lymph nodes, lung, or both is required. This can generally be done with minimally invasive procedures, such as cervical mediastinoscopy, the Chamberlain procedure (a parasternal minithoracotomy for biopsy of the aortopulmonary window or para-aortic nodes), or video-assisted thoracoscopic surgical biopsy (25).
