Management of Impacted Premolar With Root Dilaceration Caused by Radicular Cyst in Deciduous Molar: A Case Report.

Radicular cyst is the most common inflammatory odontogenic cyst in the oral cavity, but it rarely occurs in deciduous teeth. Radicular cysts in deciduous teeth can lead to root dilaceration in permanent successor teeth, resulting in impacted permanent teeth. We presented an 11-year-old boy who underwent decompression and drainage of a radicular cyst in deciduous tooth, followed by early orthodontic traction of permanent successor tooth with root dilaceration. The cyst healed successfully, and the impacted premolar was gradually aligned into the dental arch with favorable root development This …

Swept-source OCT findings in shaken baby syndrome: case report.

BACKGROUND: Our purpose was to document the swept source optical coherence tomography (SSOCT) findings in a patient with Shaken baby syndrome (SBS). CASE PRESENTATION: SSOCT was obtained without sedation in a six-month-old girl with bilateral multilayered retinal hemorrhages due to SBS. It documented vitreoretinal interface abnormalities, including internal limiting membrane (ILM) detachment with retinal traction, in association with other specific changes in the inner and outer retinal layers. Six weeks later, retinal hemorrhages had substantially resolved, and there was optic disc pallor. O…

Acute type A aortic dissection with a tear in the posterior wall of the ascending aorta early after off-pump coronary artery bypass grafting.

The patient was a 68-year-old man who underwent triple-vessel OPCAB uneventfully with aortic proximal anastomosis at one site using the saphenous vein with a mechanical device, not a side clamp, with mild traction of the ascending aorta by aortic taping. On postoperative day 7, computed tomography revealed extremely localized AAD with a tear on the posterior wall of the ascending aorta. Emergent ascending aortic replacement was successfully performed. Surprisingly, the tear extended laterally along the traction site of the tape. To our knowledge, this is the first report of AAD early after OPC…

Photopsia and a temporal visual field defect.

A 30-year-old woman presented with intermittent photopsia, a temporal visual field defect below the horizontal in her left eye, and flu-like … an intact outer retina, a remarkably thinned nerve fiber layer nasally, and peripapillary vitreous traction. Goldmann kinetic perimetry revealed a sector-shaped dense defect breaking out from the blind spot to the temporal periphery just below the horizontal in the left eye. The patient had nasal hypoplasia of the optic nerve and peripapillary vitreous tr …

Management of delayed posttraumatic cervical kyphosis.

We describe three patients with misdiagnosed unstable fractures of the cervical spine, who were treated conservatively and developed kyphotic deformity, myelopathy, and radiculopathy. All three patients were then managed with closed reductions by crown halo traction, followed by instrumented fusions. Their neurologic function was regained without permanent disability in any patient. Unstable fractures of the cervical spine will progress to catastrophic neurologic injuries without surgical fixation. Posttraumatic kyphosis and the delayed reduction of partially healed fracture dislocations by pr…

An unusual reduction technique prior to surgical treatment for traumatic spondylolisthesis in the lower cervical spine.

Traumatic spondylolisthesis in the lower cervical spine is rare and only a few cases have been reported. We present a 56-year-old man who had severe C6-C7 spondylolisthesis without major neurological complications, caused by a traffic accident. Plain CT images showed a pedicular fracture on the right side and a laminar fracture on the left side at C6, but magnetic resonance images revealed no spinal cord compression. Application of a halo brace and maintaining the neck in slight flexion without traction resulted in reduction of the spondylolisthesis to nearly normal alignment. Anterior fusion …

Association of midoesophageal diverticula with oesophageal motor disorders. Videofluoroscopy and manometry.

PURPOSE: To evaluate the prevalence and clinical significance of associated oesophageal motor disorders in patients with midoesophageal diverticula. MATERIAL AND METHODS: We retrospectively reviewed videofluoroscopic and, if available, manometric studies of 30 patients with midoesophageal diverticula. The type of diverticulum and the presence and nature of oesophageal motor disorders were assessed. RESULTS: Videofluoroscopy showed that 24 patients had 26 pulsion-type diverticula and 6 patients had 7 traction-type diverticula. Oesophageal motor disorders were demonstrated in 21 of the 24 pati…

[Central fracture-dislocation of the hip joint. Clinical analysis of 40 cases].

From 1957 to 1986, 40 cases of central fracture-dislocation of hip joint, 36 fresh and 4 old, were treated. Classification concerning the lesional patterns, indications for operative and non-operative treatment together with the factors affecting prognosis were discussed. In conclusion firstly, treatment by means of traction, simple and easy to handle, is well suited to most cases, if reduction has been satisfactory and maintained well, permitting early motion, for sufficient period of time for healing. Secondly, operation is only fit for fracture-dislocation, of which reduction has not been g…

Closed reduction of spondylolisthesis. An experience in 22 patients.

Twenty-two patients with spondylolisthesis were treated by closed reduction techniques with posterolateral arthrodesis. Ages ranged from 6 to 30 years, with an average of 18 years. Six patients were treated in skeletal traction. Postoperatively, two patients were immobilized in an ambulatory extension brace, 15 patients in a body cast incorporating one thigh, and five patients in a body cast incorporating Hoffman iliac pins and lumbar spinous process wires attached to an outrigger on the plaster. At an average of 40 months follow-up (range: 12-80 months), preoperative slip angle averaged 33 de…

Vitrectomy and fluid infusion in the treatment of delayed suprachoroidal hemorrhage after combined cataract and glaucoma filtration surgery.

I report the successful treatment of one case of massive, delayed suprachoroidal hemorrhage that occurred after combined intracapsular cataract extraction and trabeculectomy. Significant vitreous incarceration in the filtration site and consequent vitreoretinal traction were present so that a limbal approach anterior vitrectomy was necessary before choroidal drainage could be accomplished safely. An infusion of balanced salt solution through a limbal infusion cannula was employed during vitrectomy and also during drainage of suprachoroidal blood. The simultaneous intravitreal infusion helped t…

Antiproliferative drugs in the treatment of experimental proliferative vitreoretinopathy.

We used an experimental model of proliferative vitreoretinopathy (PVR) and cell-induced traction retinal detachment to study the therapeutic value of six cytotoxic drugs (actinomycin C, colchicine, cytosine arabinoside hydrochloride, 5-fluorodeoxyuridine, vinblastine sulfate, and daunomycin). Pigmented rabbits were injected with 2.5 X 10(5) cultured homologous dermal fibroblasts. At the same time, cytotoxic drugs were injected into the vitreous in an attempt to inhibit cellular proliferation. The sensitivity of the cells to the drug was also tested in vitro before injection. Daunomycin at a do…

Retinal detachment following congenital cataract surgery. I. Preoperative findings in 114 eyes.

One hundred fourteen eyes of patients with retinal detachment occurring after congenital cataract surgery were studied. Retinal detachment was typified by high incidences of men, myopia, preference for the second and fourth decades of life, and a fairly long interval after cataract surgery. Frequently found were the following: (1) undetected retinal breaks, (2) high incidences of small oval or round holes in the upper nasal quadrant near the ora serrata, (3) retinal detachment in more than one quadrant, and (4) extensive vitreous and preretinal traction. Preoperative examination was often hamp…

An autopsy case series on adventitial hemorrhages at the junction of aorta and posterior intercostal arteries - a potential mechanism of appearance.

Recently, a novel autopsy finding in deaths by hanging was reported - adventitial hemorrhages of the descending aorta at the junction with the posterior intercostal arteries. The suggested mechanism of appearance is the axial traction of the body on neck compression but also agonal convulsion-related repetitive spine hyperextension, leading to stretching and tearing of the adventitial blood vessels. So, they should appear in other deaths that share these agonal elements with hangings, such as epilepsy-related deaths, drownings, fatal electrocution or hypothermia. We report eight isolated, non-…

INNER FOVEAL IRREGULARITIES AFTER VITREOMACULAR DETACHMENT: A Morphologic Risk Factor for Macular Hole Formation in the Fellow Eye.

PURPOSE: To assess the morphologic risk of full-thickness macular hole (FTMH) formation in the fellow eye based on posterior vitreous detachment (PVD) status and preceding vitreomacular interface changes using optical coherence tomography data of the fellow eye. METHODS: The natural history of fellow eyes of patients with unilateral FTMH was reviewed for tractional maculopathies, symmetry of the foveal contour, inner and outer retinal irregularities, and PVD status on spectral domain optical coherence tomography. Posterior vitreous detachment was classified as incomplete (incomplete PVD = vit…

Hyalocytes-guardians of the vitreoretinal interface.

Originally discovered in the nineteenth century, hyalocytes are the resident macrophage cell population in the vitreous body. Despite this, … ized by anomalous posterior vitreous detachment (PVD) and vitreoschisis. These can be hypercellular tractional vitreo-retinopathies, such as macular pucker, proliferative vitreo-retinopathy (PVR), and proliferative diabetic vitreo-retinopathy (PDVR), as well as paucicellular disorders such as vitreo-macular traction syndrome and macular holes. Notably, hya …

The History and Legacy of the Foker Process for the Treatment of Long Gap Esophageal Atresia.

Historically, children afflicted with long gap esophageal atresia (LGEA) had few options, either esophageal replacement or a life of gastrostomy feeds. In 1997, John Foker from Minnesota revolutionized the treatment of LGEA. His new procedure focused on "traction-induced growth" when the proximal and distal esophageal segments were too far apart for primary repair. Foker's approach involved placement of pledgeted sutures on both esophageal pouches connected to an externalized traction system which could be serially tightened, allowing for tension-induced esophageal growth and a delayed primary…

Several specific high-resolution computed tomography patterns correlate with survival in patients with idiopathic pulmonary fibrosis.

BACKGROUND: Evidence of honeycombing in high-resolution computed tomography (HRCT) is a recognized risk factor for shortened survival in patients with idiopathic pulmonary fibrosis (IPF), but few studies have evaluated the feasibility of exploiting other specific patterns for predicting survival. The aim of this study was to examine the extent of specific HRCT patterns in IPF and determine whether they correlate with clinical features, pulmonary function tests (PFT), and survival. METHODS: Both the presence and extent of specific HRCT patterns, such as traction bronchiectasis, honeycombing, a…
