Abstract Objective: To evaluate the long-term clinical and radiographic effects of maxillary incisor root resorption in cases of ectopic canines treated during the late 1970s and 1980s in Jönköping, Sweden. Subjects and Methods: The material comprised 55 incisors in 38 subjects. The posttreatment follow-up time was 13 to 28 years. All subjects underwent intraoral radiography, 33 were referred for computed tomography or cone beam computed tomography, and 24 also underwent clinical examination. The severity of incisor root resorption was correlated with clinical characteristics. Radiographs of the resorptive lesions were documented in detail and compared with intraoral radiographs taken immediately posttreatment. Results: Four incisors in three subjects had been lost, in part because of root resorption. Of the 36 incisors with root resorption, the lesions were unchanged in 26 teeth, improved in three teeth, and exacerbated in seven. In one case the resorption had progressed to pulpal exposure, necessitating endodontic treatment. For most of the incisors, the periodontal ligament was more clearly defined and the lamina dura showed improved trabeculation. The clinical characteristics of the incisors with resorption were not significantly different from those of sound incisors. Conclusions: In this long-term follow-up, most cases of incisor root resorption induced by ectopic maxillary canines did not progress and teeth with root resorption showed no clinically relevant symptoms. The prognosis for long-term survival of teeth with resorbed roots is good, but in cases where extraction is indicated, lateral incisors with severe root resorption should be extracted in favor of healthy premolars.

ABSTRACTExternal apical root resorption (ARR) is a common iatrogenic consequence of orthodontic treatment. One of the aims of this article is to present a brief overview of the literature, including; diagnosis and etiology, with emphasis on orthodontic forces to facilitate an understand of the prevention or management of ARR in orthodontic patients. We also present a long-term follow-up observation of severe ARR, including the last obtained cone beam computed tomography (CBCT) records, to demonstrate the effect of orthodontic forces on ARR.

ABSTRACT Objective:  To analyze radiographic signs of temperomandibular joint (TMJ) osteoarthritis and clinical TMJ symptoms in patients 6 years and 32 years after treatment with a Herbst appliance. Materials and Methods:  Fourteen patients were derived from a sample of 22 with Class II division 1 malocclusions consecutively treated with a banded Herbst appliance at the age of 12–14 years old (T1-T2). The subjects were reexamined after therapy at the ages of 20 years (T3) and 46 years (T4). The TMJs of the 14 patients were analyzed radiographically (conventional lateral tomography at T3 and cone-beam computed tomography at T4) and clinically/anamnestically at T3 and T4. Results:  Six years after Herbst therapy, signs of osteoarthritis were seen in one patient. At the 32-year follow-up, two additional patients had developed signs of osteoarthritis. At the 6-year follow-up, TMJ clicking was present in two patients, though none of the patients reported TMJ pain. At the 32-year follow-up, six patients had TMJ clicking and one patient had TMJ pain. Conclusions:  This longitudinal very-long-term follow-up study after Herbst therapy revealed only minor problems from the TMJ. The TMJ findings 6 years and 32 years after Herbst treatment corresponded to those in the general population. Thus, in the very long term, the Herbst appliance does not appear to be harmful to the TMJ.

ABSTRACT Exostoses or hyperostoses are benign bony outgrowths originating from the cortical bone and depend on their location for a more precise designation. The most common types found in the oral cavity are the torus palatinus and the torus mandibularis. Buccal and palatal exostoses are located along the buccal aspect of the maxilla and/or the mandible (commonly in the premolar and molar areas) and on the palatal aspect of the maxilla (usually in the tuberosity area), respectively. The etiology of exostoses still hasn’t been enlightened but an interaction between environmental and genetic factors is accredited. They are usually asymptomatic, unless the mucosa becomes ulcerated. The frequency of exostoses increases with age, having their biggest prevalence from 60 years old, being more common in men and suffering ethnic influences. A thorough evaluation is important for the correct diagnosis since other lesions have similar clinical characteristics to the exostoses such as osteomas. The majority of exostoses are diagnosed clinically along with radiographic interpretations, making the biopsy dispensable and the treatment is usually unnecessary. The aim of this article was to describe a case report of bilateral maxillary exostosis, unusual, in a female patient. If an excessive amount of bone is present the exostoses may exhibit a relative radiopacity on dental radiographs. Initially, periapical and panoramic radiographs were performed to evaluate the alterations. Due to the size of the exostoses a concomitant Cone Beam Computed Tomography was performed to confirm the diagnosis. The patient is in follow-up.

Extrahepatic bile duct tumors, 80 per cent of which are adenocarcinomas, are rare neoplasms accounting for less than two per cent of all cancers. Carcinoid tumor of the extrahepatic bile ducts is a reportable lesion, with only approximately 50 cases described in the literature since 1959. We present a case of a primary extrahepatic bile duct carcinoid tumor resected for cure with the longest reported follow-up time (11 years) after surgery. We also summarize the existing literature with regard to this rare tumor. Our case lends strong support to the notion that extrahepatic biliary carcinoids are generally indolent lesions that, if aggressively resected, can result in excellent long-term survival. Complete excision with clear margins seems to provide the best chance of obtaining long-term survival and cure.

ABSTRACT OBJECTIVE Therapy with intrathecal colloidal gold has been used in the past as an adjunct in the treatment of childhood neoplasms, including medulloblastoma and leukemia. We describe the long-term follow-up period of a series of patients treated with intrathecal colloidal gold and emphasize the high incidence of delayed cerebrovascular complications and their management. METHODS Between 1967 and 1970, 14 children with posterior fossa medulloblastoma underwent treatment at the University of Minnesota. Treatment consisted of surgical resection, external beam radiotherapy, and intrathecal colloidal gold. All patients underwent long-term follow-up periods. RESULTS Of the 14 original patients, 6 died within 2 years of treatment; all experienced persistent or recurrent disease. The eight surviving patients developed significant neurovascular complications 5 to 20 years after treatment. Three patients died as a result of aneurysmal subarachnoid hemorrhage, and five developed ischemic symptoms from severe vasculopathy that resembled moyamoya disease. CONCLUSION Although therapy with colloidal gold resulted in long-term survival in a number of cases of childhood medulloblastoma, our experience suggests that the severe cerebrovascular side effects fail to justify its use. The unique complications associated with colloidal gold therapy, as well as the management of these complications, are presented. We recommend routine screening of any long-term survivors to exclude the presence of an intracranial aneurysm and to document the possibility of moyamoya syndrome.

Background The number of dialysis patients in Japan is rising, with an increasing number requiring cardiovascular surgery. Methods We investigated the short- and long-term outcomes in 70 dialysis patients among a total of 1124 who underwent cardiovascular surgery in our hospital between 2004 and 2016. We investigated outcomes following open surgery and identified factors that affected the prognosis. We also compared the long-term survival rate with the survival rate of the Japanese dialysis population. Results The long-term survival rate was 70.6%, 51.1%, and 19.2% after 3, 5, and 10 years, respectively. The causes of long-term death were heart disease in 8 patients, cerebrovascular disease in 7, cachexia in 3, infection in 2, and other causes in 3. The freedom from cardiac death was 88.7%, 77.9%, and 54.9% after 3, 5, and 10 years, respectively. Multivariate analysis using Cox’s proportional hazard model showed that a history of atherosclerosis obliterans (hazard ratio 5.4, p = 0.05) and mediastinitis (hazard ratio 10.2, p = 0.03) were risk factors for death in long-term follow-up, and a history of atherosclerosis obliterans was an independent risk factor for cardiac death in long-term follow-up (hazard ratio 5.3, p = 0.01). Five-year survival of the study subjects was comparable to that of the Japanese dialysis population. Conclusions The prognosis for dialysis patients after open surgery was equivalent to that of Japanese dialysis patients in general. A high proportion of late postoperative deaths were due to heart disease. Patients with atherosclerosis obliterans had a poor prognosis.

Abstract Introduction New onset AF is a known complication in patients with acute ST-segment elevation myocardial infarction (STEMI). However, whether new-onset AF affects the long-term prognosis to the same extent as pre-existing AF is not fully clarified and prescription of oral anticoagulants (OAC) in patients with new-onset AF remains a matter of debates. Purpose We aimed to assess the impact of new-onset AF in STEMI patients undergoing primary percutaneous intervention (PCI) on outcome during long-term follow-up in comparison with pre-existing AF and to evaluate effect of OAC therapy in patients with new-onset AF on survival. Methods Study sample comprised of 2277 consecutive patients with STEMI admitted to a tertiary care hospital for primary PCI from 2007 to 2010 (age 66±12 years, 70% male). AF prior to STEMI was documented by record linkage with the Swedish National Patient Register and review of ECGs obtained from the digital archive containing ECGs recorded in the hospital catchment area since 1988. SWEDEHEART registry was used as the source of information regarding clinical characteristics and events during index admission, including new-onset AF and OAC at discharge. All-cause mortality was assessed using the Swedish Cause-of-Death Register 8 years after discharge. Results AF prior to STEMI was documented in 177 patients (8%). Among patients without pre-existing AF (n=2100), new-onset AF was identified in 151 patients (7%). Patients with new-onset AF were older than those without AF history (74±9 vs 65±12 years, p<0.001), but did not differ in regard to other clinical characteristics. Among 2149 STEMI survivors discharged alive, 523 (24%) died during 8 years of follow-up. OAC was prescribed at discharge in 45 (32%) patients with new onset AF and in 49 (31%) patients with pre-existing AF, p=0.901. In a univariate analysis, both new-onset AF (HR 2.18, 95% CI 1.70–2.81, p<0.001) and pre-existing AF (HR 2.80, 95% CI 2.25–3.48, p<0.001) were associated with all-cause mortality, Figure 1. After adjustment for age, gender, cardiac failure, diabetes, BMI and smoking history, new-onset AF remained an independent predictor of all-cause mortality (HR 1.40, 95% CI 1.02–1.92, p=0.037). OAC prescribed at discharge in patients with new-onset AF was not significantly associated with survival (univariate HR 0.86, 95% CI 0.50–1.50, p=0.599). Conclusion New-onset AF developed during hospital admission with STEMI is common and independently predicts all-cause mortality during long-term follow-up after STEMI with risk estimates similar to pre-existing AF. The effect of OAC on survival in patients with new-onset AF is inconclusive as only one third of them received OAC therapy at discharge.
