Appreciate the "saw-tooth" rectum. Maximal distention of the rectum is less than the sigmoid. Other things to consider when a newborn presents with dilated small bowel loops and a "low obstruction" are: meconium ileum, distal ileal atresia, colonic atresia, and small left colon syndrome. The gull-wing appearance , also known as seagull erosions or sawtooth appearance , is classically seen in erosive osteoarthritis, typically on posteroanterior radiographs of the hands, although has also been reported in psoriatic and rheumatoid arthritis.

Barium enema demonstrates a reduced caliber rectum and sigmoid (the rectum is smaller than the descending colon) with a saw-tooth appearance to the wall. A transition point is seen at the junction between sigmoid and descending colon. 3 case questions available Annotated post evacuation film Fluoroscopy Saw-tooth appearance to the colon, usually sigmoid, with shortening of bowel, crowding of haustra and picket-fencing of folds Muscle spasm is present-may be relieved with glucagon Controversial as to whether this form can be symptomatic, i.e. pain Diverticulosis May be due to low roughage, high refined-fiber diet Scanning power view of lichen planus shows a lichenoid reaction pattern (Figure 1) characterised by the combination of degeneration of the basal layer of the epidermis and a band like lymphocytic infiltrate obscuring the dermoepidermal junction. There is irregular epidermal hyperplasia forming a characteristic saw-tooth appearance with wedge. Conversely, the lack of association of the radiologic findings of "sawtooth" appearance of mucosa and pneumatosis intestinalis is likely the result of there being a low incidence in this cohort. We found this somewhat surprising, given that when pneumatosis intestinalis or "sawtooth" appearance is present on imaging in a HSCR patient.

Understand the concepts behind particular appearance and the derivation of the radiology sign - so that you never have to mug up The sacrum is recognizable as a horizontal hyperechoic curvilinear structure, and the L5 lamina has the typical "sawtooth" appearance. The structures of the vertebral canal are visible through the intervening gap. A distinguishing feature of the L5 lamina is its shorter superior-inferior width compared with the other lumbar vertebrae. Contrast enema with water soluble iodinated contrast demonstrated a transition zone in the distal descending colon with narrowed sigmoid and distal descending colon, "saw tooth" appearance of sigmoid colon and rounding of the flexures ( Fig. 2 a-c). Sawtooth pattern on ECG Last reviewed dd mmm yyyy. Last edited dd mmm yyyy Authoring team These include: if the P waves are about 300 per minute, and there is a 3:1 block, then the ECG will have a characteristic saw-tooth appearance

Saw-tooth cardiomyopathy (STC) is a rare form of left ventricular (LV) dysplasia that may not be represented in the literature because it is underdiagnosed. Cardiac computed tomography is a valuable non-invasive study for the diagnosis of STC due to its capacity to rule out coronary lesions and identify this type of LV dysplasia. Serrated architecture with a sawtooth appearance, with serrations generally limited to the upper half of the crypts Mild nuclear enlargement, stratification and hyperchromasia, limited to the crypt bases No dilated, branched or horizontally spreading crypts No evidence of conventional dysplasia, e.g. as is seen in colorectal adenomas
Saw tooth appearance of myocardium in basal inferolateral and basal to mid lateral segments was also seen. (Figures 2, 3, and 4) Figure 2. Open in figure viewer PowerPoint. Long axis view of left ventricle, showing distinct projections of myocardium. Figure 3. Saw-tooth cardiomyopathy has a characteristic appearance in CMR and/or echocardiography, which is distinct from LVNC. Natural history is unclear, as are potential complications, but conduction abnormalities are described in previously reported cases. The pathophysiology is unknown, but family screening and genetic analyses may be reasonable.

The sawtooth wave (or saw wave) is a kind of non-sinusoidal waveform.It is so named based on its resemblance to the teeth of a plain-toothed saw with a zero rake angle.A single sawtooth, or an intermittently triggered sawtooth, is called a ramp waveform.. The convention is that a sawtooth wave ramps upward and then sharply drops. DOI: 10.1007/s11325-016-1441-x Abstract Background: We retrospectively assessed the predictive value of the spirometric sawtooth sign in terms of the odds ratio (OR) of association with a diagnosis of OSA compared to those without the sign.
