Oropharyngeal Mucocele as an Unusual Cause of Recurrent Pneumonia in a Young Infant

Background: Oral mucoceles, though frequently seen as asymptomatic lesions in young adults, very little is known about their existence in infants and the complications arising out of them in this age group. Clinical Description: A 4-month-old infant presented with a history of recurrent episodes of breathing difficulty since 15 days of life, every episode being managed as aspiration pneumonia. The child presented in the fifth such episode with tachypnea tachycardia and chest indrawing. Auscultation revealed bilateral crepitations and chest X-ray showed diffuse haziness in the bilateral chest predominantly in the right middle lobe, rest of the systemic examination being normal. Oral cavity examination showed a bluish globular bulge behind the tongue with surrounding congested mucosa and thick secretions. Management and Outcome: The baby was managed with respiratory support in the form of continuous positive airway pressure, intravenous antibiotics Piperacillin-Tazobactam, amikacin and metronidazole, and anti-reflux measures of oral Domperidone. Flexible laryngoscopy showed a cystic lesion behind the tongue and contrast-enhanced computerized tomography confirmed a hypodense lesion arising from the uvula suggestive of a mucocele. Excision of the oro-pharyngeal cystic lesion was done and the histopathological examination confirmed it to be a mucocele. The baby was gradually weaned off oxygen support and proper breastfeeding was re-established. Conclusion: This case creates awareness regarding the fact that an unsuspected oral mucocele may be the cause of recurrent respiratory symptoms in an infant, thereby reiterating the importance of oral examination even in young infants.

S212 Incidence Rates of Adenoamtous Polyps, Clinically Significant Serrated Polyps and Advanced Neoplasia in Adults Age 18-45 in a Community Hospital in the Upper Midwest Over a 15-Year Period: A Retrospective Review

Introduction: Increasing incidence of early onset colorectal cancer over time has been well described. Temporal trends regarding precursor lesions in young adults are less clearly defined. The aim of this study was to investigate trends in the rates of adenomatous colon polyps, clinically significant serrated polyps and advanced neoplasia in young adults over a 15 year period. Methods: We performed a retrospective review of all colonoscopy examinations performed in two community hospitals and an ambulatory surgery center in northern Minnesota between January 1, 2006 and December 31, 2020 in adults age 18-45. Exclusion criteria were incomplete colonoscopy exams or exams with inadequate bowel preparation. A total of 2655 colonoscopy exams were included in our review. We measured the incidence rates of adenomas, clinically significant serrated polyps (sessile serrated polyps, traditional serrated adenomas, proximal hyperplastic polyps > 4 mm and hyperplastic polyps > 9 mm) and rates of advanced neoplasia (adenoma > 9 mm, villous histology, high grade dysplasia, colon cancer) for each year in the study period. The relationship between time (as measured by year) and incidence of adenomatous polyps, clinically significant serrated polyps, advanced neoplasia and non-malignant advanced neoplasia was investigated using Spearman Rank Order Correlation (rho). Preliminary analyses were performed to ensure no violation of the assumptions. Results: There were a total of 291 cases with at least one adenoma detected (11.0% incidence rate), 63 cases with at least one clinically significant serrated polyp (2.4% incidence rate), 60 cases with advanced neoplasia (2.3% incidence) and 8 cases of colorectal cancer (0.3% incidence rate). The incidence rate of adenomatous polyps increased over the course of the study period (rho = .88, n = 15, = p < .001). The incidence of clinically significant serrated polyps increased over the study period, however this finding was not statistically significant. The incidence of advanced neoplasia increased over the course of the study period and trended towards significance (rho = .50, n = 15, p = .056). (Figure) Conclusion: Incidence rates of adenomatous colon polyps in young adults increased over the study period while rates of advanced neoplasia appeared to increase over the study period. More complete understanding of temporal trends in different precursor colon lesions in young adults may help guide endoscopists caring for young adults with lower GI symptoms.Figure 1.: Incidence of adenomatous colon polyps in young adults over time

Initial experience with magnetic resonance-guided focused ultrasound stereotactic surgery for central brain lesions in young adults.

Magnetic resonance-guided focused ultrasound (MRgFUS) is an incisionless procedure capable of thermoablation through the focus of multiple acoustic beams. Although MRgFUS is currently approved for the treatment of tremor in adults, its safety and feasibility profile for intracranial lesions in the pediatric and young adult population remains unknown. The long-term outcomes of a prospective single-center, single-arm trial of MRgFUS at Nicklaus Children's Hospital in Miami, Florida, are presented. Patients 15-22 years of age with centrally located lesions were recruited, clinically consistent with WHO grade I tumors that require surgical intervention. This cohort consisted of 4 patients with hypothalamic hamartoma (HH), and 1 patient with tuberous sclerosis complex harboring a subependymal giant cell astrocytoma (SEGA). In each case, high-intensity FUS was used to target the intracranial lesion. Real-time MRI was used to monitor the thermoablations. Primary outcomes of interest were tolerability, feasibility, and safety of FUS. The radiographic ablation volume on intra- and postoperative MRI was also assessed. All 5 patients tolerated the procedure without any complications. Successful thermoablation was achieved in 4 of the 5 cases; the calcified SEGA was undertreated due to intratumor calcification, which prevented attainment of the target ablation temperature. The HHs underwent target tissue thermoablations that led to MR signal changes at the treatment site. For the patients harboring HHs, FUS thermoablations occurred without procedure-related complications and led to improvement in seizure control or hypothalamic hyperphagia. All 5 patients were discharged home on postoperative day 1 or 2, without any readmissions. There were no cases of hemorrhage, electrolyte derangement, endocrinopathy, or new neurological deficit in this cohort. This experience demonstrates that FUS thermoablation of centrally located brain lesions in adolescents and young adults can be performed safely and that it provides therapeutic benefit for associated symptoms.

Clinical features of capsule endoscopy in young adults: A single-center retrospective study.

Background and AimCapsule endoscopy (CE) has been used in clinical examination among people of various ages, while few studies exclusively focused on the young. We aimed to explore its clinical features in young adults and those with obscure gastrointestinal bleeding (OGIB).MethodsA total of 479 young adults aged 18–44 years were analyzed, with median age of 33 years. Primary positive findings of patients were classified into four kinds of lesions, and potential risk of bleeding among patients with OGIB was assessed based on Saurin classification (P0‐2 lesions).ResultsThe overall completion rate and diagnostic yield of CE among young adults were 89.77 and 77.04%, respectively. Significant differences were found among overall completion rate/diagnostic yield and inpatient status/CE brand. Positive diagnostic yield among 157 patients with OGIB was 51.59% (P1‐2 lesions), and the significant risk of bleeding was 37.04% (P2 lesions). Among patients with OGIB in which 134 patients with a total of 216 lesions, ulceration was the commonest P2 lesions, followed by angioectasia and telangiectasia. Inpatient rate, completion rate, and diagnostic yield were higher among patients with overt OGIB, and disease categories of overt OGIB were different compared with occult OGIB.ConclusionCE is an optimal tool for discovering lesions in young adults and could play a role in evaluating the bleeding risk of young adults with OGIB.

Osteocondritis dissecans lesions of the knee restored by bone marrow aspirate concentrate. Clinical and imaging results in 18 patients

BackgroundOsteochondritis dissecans (OCD) is a common cartilage disorder that specifically affects the knees of skeletally immature and young adult patients. There have been a few treatments that have been proposed: fixation of the fragment, drilling, microfractures. The aim of this study was to analyze retrospectively clinical and imaging results obtained by treating it with one-step bone marrow-derived cells Transplantation (BMDCT) technique.MethodsFrom 2007 to 2014, 18 patients (mean-age 19.1 ± 5.0 years) affected by OCD were treated with one-step BMDC transplantation. In our observational study, clinical evaluation was performed at a scheduled follow-up through IKDC, Tegner, KOOS and EQ-VAS. X-rays and MRI were conducted preoperatively and at 12 months. At final follow-up, MRI MOCART Score was evaluated.ResultsIKDC and KOOS clinical scores showed a progressive increase. Tegner Score at final follow-up (5.3 ± 2.7) was significantly lower compared to the pre-injury level (6.5 ± 2.1); however, these results showed a statistically significant improvement that remained over time. EQ-VAS showed a significant improvement in every follow-up measure. MRI Mocart Score showed a complete or almost complete filling of the lesion in 13 patients.Conclusions“One-step” technique allows articular surface restoration with viable physiologic osteochondral tissue with a high clinical efficacy and imaging results. The number of cases is still limited, and further studies with larger sample sizes and greater follow-up evaluations are required to confirm our results. Nevertheless, we believe that BMDCT may represent a suitable option to treat OCD lesion in young adults.

Nomogram for Predicting the Severity of Coronary Artery Disease in Young Adults ≤45 Years of Age with Acute Coronary Syndrome

Background: A non-invasive predictive model has not been established to identify the severity of coronary lesions in young adults with acute coronary syndrome (ACS). Methods: In this retrospective study, 1088 young adults (≤45 years of age) first diagnosed with ACS who underwent coronary angiography were enrolled and randomized 7:3 into training or testing datasets. To build the nomogram, we determined optimal predictors of coronary lesion severity with the Least Absolute Shrinkage and Selection Operator and Random Forest algorithm. The predictive accuracy of the nomogram was assessed with calibration plots, and performance was assessed with the receiver operating characteristic curve, decision curve analysis and the clinical impact curve. Results: Seven predictors were identified and integrated into the nomogram: age, hypertension, diabetes, body mass index, low-density lipoprotein cholesterol, mean platelet volume and C-reactive protein. Receiver operating characteristic analyses demonstrated the nomogram’s good discriminatory performance in predicting severe coronary artery disease in young patients with ACS in the training (area under the curve 0.683, 95% confidence interval [0.645–0.721]) and testing (area under the curve 0.670, 95% confidence interval [0.611–0.729]) datasets. The nomogram was also well-calibrated in both the training (P=0.961) and testing (P=0.302) datasets. Decision curve analysis and the clinical impact curve indicated the model’s good clinical utility. Conclusion: A simple and practical nomogram for predicting coronary artery disease severity in young adults≤45 years of age with ACS was established and validated.

Dredging: A conservative surgical approach for treatment of large cystic lesions of the jaws.

Treatment modalities of odontogenic cystic lesions of the jaws range from conservative to radical. "Dredging" may be considered the "middle path" between conservative and radical treatment options. It comprises three entities-decompression, followed by repeated scraping of the lesion, and finally, peripheral ostectomy providing margin clearance but without significant morbidity. To evaluate the outcome of "dredging" in the management of large cystic lesions of the jaws, without major resections and maintaining normal functions. This prospective study was conducted on 30 patients. Inclusion criteria were odontogenic cystic lesions at least 2 cm in size either in the proximity of vital structures or in children with developing tooth germs or so large that upon enucleation, can result in pathological fracture. All underwent decompression followed by dredging performed at every 2 to 3 months intervals. Drastic decrease in size of the lesion as measured on Cone Beam Computed Tomography (CBCT) and new bone formation was evident in all patients. The total Reduction Rate (RR) of the cystic lesions was 88.79% in 9.2 months. RR was highest in Calcifying epithelial odontogenic cyst (CEOC) followed by Unicystic Ameloblastoma (UA), Odontogenic Keratocysts (OKC), Dentigerous cyst (DC), and Radicular Cyst (RC) in CBCT. The mean speed of shrinkage was fastest in CEOC, followed by OKC, UA, RC, and DC after dredging. Shrinkage was higher in patients below 20 years of age (P 0.012) and patients with large cystic lesions (P 0.00447). The results suggest that dredging with regular, long-term follow-up can be a successful treatment method for large cystic lesions in young adults. This method includes the benefits of both conservative and radical treatment methods but lacks the disadvantages of either.

Subclinical Vascular Brain Lesions in Young Adults With Acute Ischemic Stroke.

Subclinical vascular brain lesions are highly prevalent in elderly patients with stroke. Little is known about predisposing factors and their impact on long-term outcome of patients with stroke at a young age. We quantified magnetic resonance-defined subclinical vascular brain lesions, including lacunes and white matter hyperintensities, perivascular spaces and cerebral microbleeds, and assessed total small-vessel disease (SVD) score in patients with first-ever acute ischemic stroke aged 18 to 45 years, and followed them up, as part of the multicentre Italian Project on Stroke in Young Adults. The primary end point was a composite of ischemic stroke, transient ischemic attack, myocardial infarction, or other arterial events. We assessed the predictive accuracy of magnetic resonance features and whether the addition of these markers improves outcome prediction over a validated clinical tool, such as the Italian Project on Stroke in Young Adults score. Among 591 patients (males, 53.8%; mean age, 37.5±6.4 years), 117 (19.8%) had subclinical vascular brain lesions. Family history of stroke was associated with lacunes (odds ratio, 2.24 [95% CI, 1.30-3.84]) and total SVD score (odds ratio, 2.06 [95% CI, 1.20-3.53] for score≥1), hypertension with white matter hyperintensities (odds ratio, 2.29 [95% CI, 1.22-4.32]). After a median follow-up of 36.0 months (25th-75th percentile, 38.0), lacunes and total SVD score were associated with primary end point (hazard ratio, 2.13 [95% CI, 1.17-3.90] for lacunes; hazard ratio, 2.17 [95% CI, 1.20-3.90] for total SVD score ≥1), and the secondary end point brain ischemia (hazard ratio, 2.55 [95% CI, 1.36-4.75] for lacunes; hazard ratio, 2.61 [95% CI, 1.42-4.80] for total SVD score ≥1). The predictive performances of the models, including magnetic resonance features were comparable to those of the random model. Adding individual magnetic resonance features to the Italian Project on Stroke in Young Adults score did not improve model prediction. Subclinical vascular brain lesions affect ≈2 in 10 young adults with ischemic stroke. Although lacunes and total SVD score are associated with thrombotic recurrence, they do not improve accuracy of outcome prediction over validated clinical predictors.

Sex differences in the prevalence and determinants of HPV-related external genital lesions in young adults: a national cross-sectional survey in Brazil

BackgroundExternal genital lesions (EGL) are the most common sexually transmitted infections (STIs). We aimed to evaluate the prevalence, determinants and sex differences in EGL among young adults from Brazil.MethodsOverall, 7694 participants (aged 16 to 25 years) underwent an interview, genital examination and sampling for HPV genotyping.ResultsThe prevalence of EGL was 4.08% (234) and is more frequent in men (5.72%) than women (2.31%) (p < 0.001). Genital lesions were significantly associated with male sex, infection by high-risk and multiple HPV types, having more than two sexual partners in the last year, smoking status and the presence of other STI. While alcohol use was associated with a higher prevalence of EGL in women, same-sex sexual relationship increase the prevalence in men. In the EGL group, 67.79% (p = 0.032) were positive for HPV infection and the types HPV6 and HPV11 were the most prevalent ones.ConclusionThe prevalence of EGL in young adults was consistently high, and most cases were associated with genital HPV infection and STIs. Although men have a higher prevalence, both sexes share most genital lesion determinants. The promotion of sexual education and vaccination especially focus in young men, who are usually outside the targets of primary health care programmes, can prevent EGL in Brazilian young adults.

Vascular White Matter Lesions in Young Adults: A Neurology Outpatient Clinic Registry

Introduction: Although frequently assumed to be age-related changes, vascular white matter lesions (WML) are sometimes found in young adults. Etiology is usually attributed to sporadic small vessel disease; nevertheless, genetic disorders may also be implicated. We aimed to characterize the population of young adults with vascular WML in Neurology outpatient clinics. Methods: Neurologists from 12 Portuguese hospitals were invited to include patients aged 18–55 years evaluated in consultation, with vascular WML on MRI, scoring II or III in the Fazekas scale. Central imaging validation was performed by 2 independent, blinded, Neuroradiologists. Demographic and clinical data were collected as well as results of investigations performed. Results: During 2 years, 77 patients were included (mean age 47.7 years). Vascular risk factors were present in 88.3% patients (hypertension in 53.2%) and previous history of stroke in 36.4%. Patients without history of stroke were younger (46.6 ± 7.2 vs. 49.6 ± 3.9 years, p = 0.045) and had fewer vascular risk factors (p < 0.001). They were more frequently females (87.8 vs. 46.4%, p < 0.001), and headache (30.6 vs. 3.6%, p = 0.007), contrary to focal symptoms (16.3 vs. 53.6%, p = 0.001), was the most frequent reason of referral. Etiological investigations performed differed between Neurologists. A genetic disorder was identified in 6 out of 58 patients (CADASIL n = 5; COL4A1 n = 1). Conclusion: Young adults with vascular WML evaluated in Neurology outpatient clinics concentrate in the oldest age groups. Vascular risk factors should be screened carefully in this population. Among patients without history of stroke, females largely outweigh males. Diagnostic investigations performed do not follow a standardized protocol.

Supraclavicular Brachial Plexus Approach for Excision of C8 Nerve Root Schwannoma: 3-Dimensional Operative Video.

Brachial plexus tumors are uncommon lesions in young adults. The majority of these are benign peripheral sheath tumors. In this 3-dimensional video, we present a case of a 19-yr-old female who presented to the neurosurgical outpatients with an anterior neck lump. It has been present for months, causing occasional numbness and paraesthesia in the distribution of the left ring finger. There was no objective weakness in finger flexion with normal long flexors reflexes. The cervical spine and supraclavicular brachial plexus were investigated with a magnetic resonance imaging (Gadolinium) scan (Figure1). It demonstrated 30×20×20 mm lesion adjacent to the C8 nerve arising from the neural foramen, however, mostly occupying the space lateral to it. The patient was consented for resection of the tumor. This was done via the supraclavicular brachial plexus approach. The brachial plexus nerves were macroscopically demonstrated lateral to the anterior scalene muscle. The intraoperative electrophysiology was used to directly stimulate the nerves, which aided in accurate tracking during the dissection. The tumor was exposed after tracing the C8 nerve deep and medial to the anterior scalene muscle. It was resected down to the foramen, reaching the level of the epidural venous plexus, while C8 was spared. The patient recovered with no neurological deficit. The histopathology confirmed grade 1 schwannoma. Subsequently, there was no radiological follow-up performed. This case demonstrates the surgical dissection of supraclavicular brachial plexus in 3-dimensions while describing the unusual dissection medial to scalenus anterior muscle.

Treatment of unstable knee osteochondritis dissecans in the young adult: results and limitations of surgical strategies-The advantages of allografts to address an osteochondral challenge.

Joint surface incongruence resulting from osteochondritis dissecans (OCD) alters the articular physiologic congruence, increasing the contact stress on adjacent joint surfaces and accelerating wear and the cascade of joint degeneration. Accordingly, the restoration of articular surface integrity is of major importance, especially in young adults where, in lesions left untreated or following simple fragment excision, early osteoarthritis can be anticipated. Therefore, the treatment algorithm in unstable knee OCD of the young adult foresees surgical options to restore the articular surface. Several procedures have been proposed, including refixation of the detached fragment bone marrow stimulation, osteochondral autograft implantation, fresh osteochondral allograft transplantation, and cell-based or cell-free regenerative techniques. The aim of this review was to summarize the evidence for these surgical strategies, reporting their results and limitations. The overall evidence documents positive results for each of the assorted surgical procedures applied to treat unstable OCD, thus indicating support for their selected use to treat osteochondral defects paying particular attention to their specific indications for the lesion characteristics. The fixation of a good quality fragment should be pursued as a first option, while unfixable small lesions may benefit from autografts. For large lesions, available cell-based or cell-free osteochondral scaffold are a feasible solution but with limitation in terms of regenerated tissue quality. In this light, fresh allografts may offer articular surface restoration with viable physiologic osteochondral tissue providing a predictably successful outcome, and therefore they may currently represent the most suitable option to treat unstable irreparable OCD lesion in young adults. LEVEL OF EVIDENCE: V.

Diagnostic value analysis of capsule endoscopy in obscure gastrointestinal bleeding patients of different ages

Objective: To evaluate the diagnostic value of capsular endoscopy in patients with obscure gastrointestinal bleeding (OGIB) in different age groups, and assess its effectiveness and safety. Methods: A total of 216 patients who were diagnosed with OGIB between March 2005 and March 2016 at Department of Gastroenterology of Peking Union Medical College Hospital were retrospectively reviewed. They were assigned into three groups: young adults, middle-aged and elderly. The demographic characteristics, clinical manifestations, working performance as well as endoscopic features in each group were collected and analyzed. Results: The detection rate and diagnosis rate of the young adults and middle-aged group were 98.53% vs 98.51% (P=0.992), 92.65% vs 91.04% (P=0.734), while those between the young adults and the elderly group were 98.53% vs 91.14% (P=0.109), 92.65% vs 87.34% (P=0.289), and 98.51% vs 91.14% (P=0.113) and 91.04% vs 87.34 (P=0.475) between the middle-aged and elderly group. No significant difference existed in either detection rates nor diagnostic rates between the different age groups. The distribution of the small intestinal lesions varied between the different age groups. The top three common lesions in young adults were vascular malformation, small intestine ulcer and Crohn's disease, while in the middle-aged group vascular malformation, non-specific enteritis and small intestine ulcer were the most common. Patients in elderly group were most likely to have vascular malformation, small intestine ulcer and erosion. Conclusions: For patients of any age with OGIB, capsule endoscopy is a safe, effective and comfortable examination which can be widely used in clinical practice.

Symptomatic Surgically Treated Non-neoplastic Cysts of the Central Nervous System: A Clinicopathological Study From Pakistan.

To report clinicopathologic features of symptomatic surgically removed non-neoplastic cysts of the central nervous system (CNS). Case series. The Aga Khan University Hospital, Karachi, from 2003 to 2012. All non-neoplastic CNS cysts reported during the study period were retrieved and reviewed. Age, gender, location, histologic type and clinical features were noted. A total of 124 cysts were diagnosed in the study period. These included 44 epidermoid cysts (mean age 30.5 ± 13.8 years), 35 colloid cysts (mean age 31 ±13.2 years), 32 arachnoid cysts (mean age 24.8 ±20.2 years), 6 dermoid cysts, 3 enterogenous cysts and Rathke's cleft cysts each and 1 ependymal cyst. All cyst types mainly presented in young adults in both genders with signs and symptoms of a mass lesion. Non-neoplastic cyst mainly presented like a CNS mass lesion in young adults. Epidermoids were the most common type of these cysts in the present series followed by the colloid and the arachnoid cysts.

Retrospective analysis of jaw biopsies in young adults. A study of 1599 cases in Southern Brazil.

BackgroundTo evaluate the prevalence and the characteristics of jaw lesions diagnosed in young adults aged 20 to 30 years in a southern Brazil reference center, over a period of 25 years. And to analyze the concordance between clinical and histological diagnosis.Material and MethodsIn this cross-sectional retrospective study, the biopsies files from this center were retrieved and data regarding sex, age, bone localization, clinical and histological diagnosis were collected. The histological diagnosis were grouped into the categories Cystic lesions of odontogenic origin, Periapical inflammation, Odontogenic tumors, Bone diseases, Health tissue and Nonspecific diagnostic. Absolute and relative frequencies were estimated with descriptive analysis. The agreement between clinical and histological diagnosis was measured through Kappa statistic.ResultsA total of 18,181 histopathological analysis were performed during the period of the study, registering 1,599 jaw lesions in young adults. The average age of individuals was 24,59 years (SD 3,1). Nine hundred ninety-one (62%) lesions were found in females and 608 (38%) in males. More than half of pathologies were cystic lesions of odontogenic origin (822/51.4%), followed by periapical inflammation (282/17.6%). Regarding the site of lesions, more than half occurred in posterior mandible (877/54.8%), followed by posterior maxilla (339/21.2%). The most frequent entities were periapical cyst, chronic periapical granuloma, dental follicle and paradental cyst, corresponding to a total of 1,202 (75.2%) evaluated cases. In relation to the analysis of concordance between clinical and histological diagnosis the general Kappa index was 0.5, which is considered moderate. Finally, the findings confirm data from literature about the most frequent jaw pathologies in young adults and serve as aid for preventive measures of some entities. Additionally, they can improve the formulation of differential diagnosis and the patient management. Key words: Jaw, biopsy, retrospective studies, young adult, Brazil.

Analysis of short and long-term results of horizontal meniscal tears in young adults

IntroductionSymptomatic horizontal meniscal tears are rare but worrisome lesions in young adults. These are overuse injuries not amenable to the classic arthroscopic sutures. An open meniscal repair allows the meniscal lesion to be suture vertically, perpendicular to its in the vascularized zone. The purpose of this study was to evaluate the short and long-term clinical and radiological outcomes of the aforementioned surgical technique. Material and methodThe first cohort consisted of 24 patients operated between 2009 and 2011 (6 women, 18 men; mean age 26years) having 11 lateral and 13 medial meniscal tears. The second cohort was of 10 patients operated between 2001 and 2002 (3 women, 7 men; mean age 24years) having 8 lateral and 2 medial meniscal tears. Patients were reviewed at the last follow-up using the IKDC, Lysholm and KOOS scores. Patients in the first cohort had an MRI, while those in the second cohort had X-rays. ResultsEighteen patients in the first cohort were reviewed with a mean follow-up of 2years (12–45months) and 9 patients from the second cohort were reviewed after 10years (97–142months). In the first cohort, one patient required secondary menisectomy. The mean Lysholm score was 90 and the subjective IKDC was 85. Every MRI examination found reduced extent and intensity of the hyperintense signal. In the second cohort, no patients required secondary meniscectomy. Two patients had joint space narrowing (less than 50%) on radiographs. The mean Lysholm score was 99 and the subjective IKDC was 91. ConclusionOpen repair of horizontal meniscal tears in young adults leads to good subjective and objective results in the short term, which are maintained in the long-term. Level of evidenceLevel IV – retrospective study.

Inner Cyst Approach, Remove Bronchial Cervical Cyst

Although most cystic lesions in young adults represent a branchial cleft cyst, the bronchial cervical cyst is not rare (Acta Oto-Laryngologica 2010;130:300). Surgical excision is both diagnostic and curative and also eliminates the risk of infection or recurrence. As we have all known, it is hard to protect some important structures in an inflamed tissue, especially in infants. However, a correct approach can avoid this kind of iatrogenic injury. An accurate diagnosis is always by pathologic examination. The diagnosis can be made before operation when finding cartilage in the nodule. We present the preoperative diagnosis by finding gas in the nodule and removed it by inner cyst approach without surrounding tissue injury.

Congenital valvular aortic stenosis in young adults: Predictors for rate of progression of stenosis and aortic dilatation

Congenital aortic stenosis (AS) is the most common obstructive left-sided cardiac lesion in young adults, however little is known about the progression in adults. Therefore, we aimed to evaluate the progression rate of AS and aortic dilatation in a large multicenter retrospective cohort of asymptomatic young adults with congenital valvular AS. Data were obtained from chart abstraction. Linear mixed-effects models were used to evaluate the progression of AS and aortic dilatation over time. A joint model combining longitudinal echocardiographic and survival data was used for survival analysis. A total of 414 patients (age 29 ± 10 years, 68% male) were included. Median follow-up duration was 4.1 (2.5-5.1) years (1587 patient-years). Peak aortic velocity was 3.4 ± 0.7 m/s at baseline and did not change over time in the total patient population (-0.01 ± 0.03 m/s/year). Increased left ventricular mass was significantly associated with faster AS progression (p<0.001). Aortic dilatation was present in 34% at baseline and 48% at follow-up (p<0.001). The aortic diameter linearly increased over time with a rate of 0.7 ± 0.2mm/year. Rate of aortic dissection was 0.06% per patient-year. Seventy patients required an aortic valve intervention (4.4% per patient-year), with AS progression rate as most powerful predictor (HR 5.11 (95% CI 3.47-7.53)). In the majority of patients with mild-to-moderate congenital AS, AS severity does not progress over time. However patients with left ventricular hypertrophy are at risk for faster progression and should be monitored carefully. Although aortic dissections rarely occur, aortic dilatation is common and steadily progresses over time, warranting serial aortic imaging.

Silent ischemic lesions in young adults with first stroke are associated with recurrent stroke

To determine the association between silent ischemic lesions (SILs) on baseline brain MRI and recurrent stroke in young adults with first-ever ischemic stroke. This was a single-center retrospective study of adult patients aged 18-50 years with first-ever ischemic stroke investigated by brain MRI between 2002 and 2009. Silent brain infarcts (SBIs) were defined as focal T2 hyperintensities ≥ 3 mm without corresponding focal symptoms, and leukoaraiosis was defined as focal, multifocal, or confluent hyperintensities on T2-weighted sequences. The primary outcome was recurrent stroke. A forward stepwise Cox regression model was used to determine whether SILs were independently associated with recurrent stroke. A total of 271 eligible patients were identified in the database: 89 did not undergo MRI imaging and 12 patients had inadequate follow-up, leaving a study population of 170 patients. MRI demonstrated SILs in 48 of 170 (28.2) patients. No patients had isolated leukoaraiosis. Hypertension (p = 0.049), migraine with aura (p = 0.02), and cardiovascular disease (p = 0.04) were associated with SIL. Mean follow-up duration was 25 ± 7 months. Among patients with SILs, 11 of 48 (23%) had a recurrent stroke vs 8 of 122 (6.5%) patients without SIL (p = 0.003). After multivariate Cox regression, SILs remained independently associated with recurrent stroke (hazard ratio [HR] 3.2, 95% confidence interval [CI] 1.2-8.6, p = 0.02), as did the combination of SBIs and leukoaraiosis (HR 7.3, 95% CI 2.3-22.9, p = 0.003). In adults ≤ 50 years old with first-ever ischemic stroke, SILs are common and independently predict recurrent stroke.
