[Ileocolonic intussusception in an adolescent patient with cystic fibrosis].

Arch Argent Pediatr 2020 06;118(3):e338-e341

Universidad Autónoma de Nuevo León, Facultad de Medicina y Hospital Universitario "Dr. José Eleuterio González".

Intestinal intussusception occurs when a proximal segment of the intestine telescopes into the lumen of an adjacent distal segment, causing intestinal obstruction. It is a common cause of acute abdomen in the first two years of life, but rare in older children. A 16-year-old male with a diagnosis of cystic fibrosis presented with symptoms compatible with distal intestinal occlusion syndrome. Read More

Quality of occlusal outcome following space closure in cases of lower second premolar aplasia using lingual orthodontic molar mesialization without maxillary counterbalancing extraction.

Head Face Med 2018 Sep 24;14(1):17. Epub 2018 Sep 24.

Private Practice, Lindenstraße 44, Bad Essen, 49152, Germany.

Background: Controlled space closure in cases of isolated lower second premolar aplasia (ILSPA) without maxillary counterbalancing extraction is challenging. Anterior anchorage loss may occur during space closure resulting in compromised occlusal results in terms of an absence of proper canine guidance during laterotrusive mandible movements. In order to evaluate the effectiveness of Herbst telescope anchorage in combination with double-cable, pull mechanics and a completely customized lingual appliance for orthodontic space management in cases of ILSPA, we tested the null hypothesis that there is a significant deterioration in the sagittal canine relationship towards an Angle-Class-II occlusion expressed as a loss of anterior anchorage following space closure with molar mesialization.

Pediatric ileocolic intussusception: new observations and unexpected implications.

Pediatr Radiol 2019 01 19;49(1):76-81. Epub 2018 Sep 19.

Division of Pediatric Surgery, Mayo Clinic, Rochester, MN, USA.

Background: Ileocolic intussusception occurs when the terminal ileum "telescopes" into the colon. We observed that ileocolic intussusception lengths are similar regardless of location in the colon.

Objective: To examine the uniformity of ileocolic intussusception length and its relationship to colon location, symptom duration and reducibility. Read More

Limited utility of plain abdominal radiographs in evaluating intussusceptions secondary to long indwelling feeding tubes.

J Clin Imaging Sci 2013 28;3. Epub 2013 Feb 28.

Radiology Department, University of California Irvine, Orange, CA, USA.

Adult intussusception (AI) is relatively rare and can be a difficult clinical diagnosis, often requiring cross-sectional imaging for confirmation. Unfortunately, intussusceptions in the setting of indwelling long enteral feeding tubes have been predominantly characterized in the pediatric population with minimal investigation in adults. We report three cases of AI in patients with long feeding catheters serving as anatomic lead points leading to intussusception diagnosed on cross-sectional imaging. Read More

The use of telescoped flow diverters as an endovascular bypass in the management of symptomatic chronic carotid occlusion.

J Clin Neurosci 2012 Jul 1;19(7):1026-8. Epub 2012 May 1.

Department of Neurosurgery, Hadassah-Hebrew University Medical Center, P.O. Box 12000, Jerusalem 91120, Israel.

Flow diverters constitute a new generation of flexible self-expanding, stent-like devices with a high-metal surface-area coverage for the endovascular management of wide-necked, fusiform, large, and giant unruptured intracranial aneurysms. They achieve aneurysm occlusion through endoluminal reconstruction of the dysplastic segment of the parent artery that gives rise to the aneurysm. To our knowledge, there is no report on the use of flow diverters for the management of occlusive cerebrovascular disease. Read More

Intussuception at atypical ages in children and adults--11 years experiences.

Pol Przegl Chir 2011 Jun;83(6):304-9

Department of Pediatric Surgery, Imam Khomeini Hospital, Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran.

Unlabelled: Intussusception is a curious anatomic condition characterized by the invagination of one segment of the gastrointestinal tract into the lumen of an adjacent segment. Once initiated, additional intestinal telescopes into the distal segment, causing the invaginated intestine to propagate distally within the bowel lumen. The aim of the study was to evaluate the clinical manifestation, etiology, and outcome of intussuception at atypical ages. Read More

Intussusception of the appendix mimicking appendicitis during pregnancy: a case report.

J Reprod Med 2009 May;54(5):327-9

Department of Obstetrics and Gynecology, Medical University of South Carolina, 96 Jonathan Lucas Street, CBS 634F, Charleston, SC 29425, USA.

Background: Intussusception occurs when a segment of bowel and its associated mesentery telescopes into the lumen of the adjacent distal bowel. Appendiceal intussusception is a rare form of ileocoloc intussusception, is rarely diagnosed preoperatively, can mimic appendicitis and has not been previously reported during pregnancy.

Case: A 31-year-old gravid woman at 27 1/7 weeks' gestation presented with symptoms suggestive of acute appendicitis and was found at laparoscopy to have complete appendiceal intussusception. Read More

Adult intussusception presenting with target sign.

ScientificWorldJournal 2008 Nov 22;8:1154-5. Epub 2008 Nov 22.

Department of Medicine, Johns Hopkins Bayview Medical Center, Johns Hopkins University School of Medicine, Baltimore, MD, USA.

Intussusception occurs when a proximal bowel segment telescopes into a contiguous distal portion. This report describes a rare case of idiopathic intussusception in a 48-year-old female, complaining of right-sided abdominal pain. The abdominal CT scan presents a classic target lesion, representing the cross-sectional image of the intussusceptum layers inside the outer intussuscipiens. Read More

The effect of magnification on the iatrogenic damage to adjacent tooth surfaces during class II preparation.

J Dent 2003 May;31(4):291-6

Department of Operative, Preventive and Paediatric Dentistry, School of Dental Medicine, University of Bern, Bern, Switzerland.

Objectives: To determine the amount of damage to adjacent surfaces during cavity preparation of approximal box-cavities by using either no magnification or an individually adapted surgical telescope.

Materials And Methods: Nine dentists prepared in a mannequin head 4 approximal (class II) box-cavities without magnification using a high speed handpiece with lighting from a dental unit. At least 2 months later the test was repeated with a surgical telescope system with integrated light. Read More

D S Parsons

Ann Otol Rhinol Laryngol 1993 Nov;102(11):834-6

Division of Otolaryngology, University of Missouri School of Medicine, Columbia 65212.

The tracheoscope is a bronchoscope without the side ventilating ports at the distal tip. It has been used for decades, implementing diagnostic and therapeutic procedures in the subglottis and cervical and thoracic trachea. The closed tube tracheoscope allows excellent control of the airway with maintenance of continuous anesthesia and ventilation. Read More

Oblique sliding metatarsal osteotomy for pressure metatarsalgia.

Gaoxiong Yi Xue Ke Xue Za Zhi 1992 Aug;8(8):403-11

Department of Orthopaedic Surgery, Kaohsiung Medical College, Taiwan, Republic of China.

The transverse arch of the foot is formed by metatarsals which heads lie in a straight line to endure most of the loading of the forefoot. Malalignment of one or more metatarsal heads will result in increased loading and produce local tender plantar callosity. The treatment of pressure metatarsalgia must aim for it's pathomechanic cause, that is, hyper-extension of metatarsophalangeal joint. Read More

Electronic imaging in endoscopy.

Surg Endosc 1988 ;2(4):227-33

Department of Surgery, Cedars-Sinai Medical Center, Los Angeles, CA 90048.

Endoscopy evolved from a hollow tube view of visually restricted areas into an expansive, distal representation of the anatomy. Rod lens telescopes, improved coherent imaging bundles, superior light sources, and other optical advances enhanced endoscopic observations. Yet complicated endoscopic procedures remained visible to the endoscopist alone, relegating assistance and consultation to verbal description of sophisticated visual observation. Read More
