RESUMEN
Purpose@#To analyze the clinical characteristics of patients with acute acquired comitant esotropia, evaluate the outcomes of augmented medial rectus muscle recession, and propose indicators for determining the appropriate surgical dosage. @*Methods@#Data of patients with acute acquired esotropia who underwent medial rectus recession between 2016 and 2022 were retrospectively analyzed. The amount of medial rectus muscle recession was 1-2 mm greater than for other types of esotropia. Surgical success was assessed by reference to the angle of deviation and diplopia status 6 months after surgery. We investigated the amount of additional recession required for favorable surgical outcomes, the characteristics of groups that required augmentation, and changes in surgical amount according to the deviation angle. @*Results@#A total of 38 patients were included; the average refractive error was -3.79 ± 3.11 diopters (D). Patient age at the time of surgery was 25.6 ± 18.2 years and the preoperative deviation angle was 38.1 ± 11.5 prism diopters (PD). The amount of medial rectus muscle recession was 6.25 ± 1.4 mm, i.e., 1.2 ± 1.0 mm greater than during other surgeries. The average augmentation was 24.1 ± 18.8%. The motor surgical success rate was 92.1% and the sensory success rate was 97.4%. The required augmentation was 26.9% for those with angles of deviation 40 PD. Patients who required augmentation > 25% were older, and the surgical effect was greater as the angle of deviation increased. @*Conclusions@#To ensure successful surgical outcomes of patients with acute acquired comitant esotropia, it is essential to increase the amount of medial rectus recession compared to that during other surgeries; the average augmentation was 24% in this study.
RESUMEN
Background@#Enlarged perivascular space (ePVS) is recently reported to be associated with cerebral small vessel disease (SVD) and Alzheimer’s disease (AD). The topographical location of ePVS may relate to the underlying pathology; basal ganglia (BG)-ePVS has been associated with cerebral vascular diseases and centrum semi-ovale (CSO)-ePVS associated with cerebral amyloid angiopathy (CAA). However, the effects of ePVS on various neurological conditions remain still controversial. To investigate the clinical relevance of ePVS in neurodegenerative diseases, we tested relationships between ePVS and cognition, markers of SVD, vascular risk factors, or amyloid pathology. @*Methods@#We retrospectively reviewed 292 patients (133 AD dementia, 106 mild cognitive impairment, 39 other neurodegenerative diseases, 14 subjective cognitive decline) who underwent both amyloid positron emission tomography and brain magnetic resonance imaging. Vascular risk factors and cognitive tests results were collected. The ePVS in the BG and CSO, SVD markers and the volume of white matter hyperintensities were measured. @*Results@#There were no significant differences in the severity and distribution of ePVS among clinical syndromes. Both BG- and CSO-ePVS were not related to cognitive function. Patients with lacunes were more likely to have high-degree BG-ePVS. High degree CSO-ePVS had an odds ratio (OR) for amyloid positive of 2.351, while BG-ePVS was a negative predictor for amyloid pathology (OR, 0.336). @*Conclusions@#Our findings support that ePVS has different underlying pathologies according to the cerebral topography. BG-ePVS would be attributed to hypertensive angiopathy considering the relation with SVD markers, whereas and CSO-ePVS would be attributed to CAA considering the association with amyloid pathology.
RESUMEN
Objectives@#Disability weights require regular updates, as they are influenced by both diseases and societal perceptions. Consequently, it is necessary to develop an up-to-date list of the causes of diseases and establish a survey panel for estimating disability weights. Accordingly, this study was conducted to calculate, assess, modify, and validate disability weights suitable for Korea, accounting for its cultural and social characteristics. @*Methods@#The 380 causes of disease used in the survey were derived from the 2019 Global Burden of Disease Collaborative Network and from 2019 and 2020 Korean studies on disability weights for causes of disease. Disability weights were reanalyzed by integrating the findings of an earlier survey on disability weights in Korea with those of the additional survey conducted in this study. The responses were transformed into paired comparisons and analyzed using probit regression analysis. Coefficients for the causes of disease were converted into predicted probabilities, and disability weights in 2 models (model 1 and 2) were rescaled using a normal distribution and the natural logarithm, respectively. @*Results@#The mean values for the 380 causes of disease in models 1 and 2 were 0.488 and 0.369, respectively. Both models exhibited the same order of disability weights. The disability weights for the 300 causes of disease present in both the current and 2019 studies demonstrated a Pearson correlation coefficient of 0.994 (p=0.001 for both models). This study presents a detailed add-on approach for calculating disability weights. @*Conclusions@#This method can be employed in other countries to obtain timely disability weight estimations.
RESUMEN
Purpose@#This study examined the meal-kit consumption practices of adults in their 20s and 30s and analyzed the properties that should be given priority for improvement among the selection attributes to improve the quality of meal-kits. @*Methods@#Statistical analyses were conducted using the SPSS program (ver. 28.0) for χ2-test, t-test, one-way analysis of variance, Duncan’s multiple range test, factor analysis, and Importance-Satisfaction Analysis (ISA). @*Results@#Of the 249 subjects surveyed, 85.5% had some experience of purchasing meal-kits, with significantly more females than males (p < 0.01), significantly more married people than single people (p < 0.05), significantly more employed people than unemployed people (p < 0.05). Meal-kits were purchased most frequently for meals (60.6%), from discount stores or supermarkets (44.6%), and priced between 10,000 won and 20,000 won per person (46.9%). The overall satisfaction with meal-kits was 4.1 out of 5.0 points. The frequency of purchases was Korean soup dishes (69.5%), Korean main dishes (47.4%), and Korean street snacks (46.9%). Factor analysis of the meal-kit selection attributes revealed, 4 factors: ‘quality of food,’ ‘packaging and diversity,’ ‘quality of meal-kit,’ and ‘convenience and price.’ Compared to single-person households, multi-person households placed significantly higher importance on the ‘quality of food,’ ‘packaging and diversity,’ and ‘quality of meal-kit.’ The factor, ‘packaging and diversity’ were significantly higher in the importance evaluation scores for females (p < 0.01), married people (p < 0.05), and people in their 30s (p < 0.05) among meal-kit consumers. According to the ISA results, a critical aspect that meal-kit manufacturers or sellers should strengthen is ‘price.’ @*Conclusion@#Meal-kit products will need to be developed for various purposes that offer high value for money that can satisfy the consumers’ needs to improve the satisfaction of meal-kit consumers.
RESUMEN
Background/Aims@#Median arcuate ligament syndrome (MALS) is known as chronic recurrent abdominal pain related to compression of the celiac artery by the median arcuate ligament. We aim to seek the specific mechanism of the pain by evaluating symptoms and radiological characteristics on abdominal CT scans. @*Methods@#We analyzed 35 patients who visited the emergency room for recurrent abdominal pain after cholecystectomy. We classified the characteristics of patients as 4 clinical components and 2 radiological components. We defined the sum of weighted clinical scores and weighted radiological scores as nutcracker ganglion abdominal pain syndrome (NCGAPS) scores. We categorized the patients into 3 groups classified by the degree of NCGAPS scores. The 3 patients with top-3 NCGAPS scores were recommended for CT angiography. @*Results@#When the suspicion was graded by NCGAPS scores, post stenotic dilatation was significantly different among all groups (P < 0.001).The clinical components of pain varied positional or respirational change and continuous pain were significantly different among all the groups (P < 0.01). NCGAPS scores can remarkably differentiate highly suspicious patients in comparison to simply combined scores. Only 1 patient in the highly suspicious group by NCGAPS scores took the CT angiography and was confirmed with NCGAPS. @*Conclusions@#We suggest renaming MALS as NCGAPS, nutcracker celiac ganglion abdominal pain syndrome, to better explain the mechanism of the recurrent abdominal pain. Further studies on the diagnostic cutoff of clinical and radiological scores of NCGAPS are needed not to miss the diagnosis of NCGAPS.
RESUMEN
Objective@#This study aimed to investigate the prevalence and status of dyslipidemia management among South Korean adults, as performed by the Korean Society of Lipid and Atherosclerosis under the name Dyslipidemia Fact Sheet 2022. @*Methods@#We analyzed the lipid profiles, age-standardized and crude prevalence, management status of hypercholesterolemia and dyslipidemia, and health behaviors among Korean adults aged ≥20 years, using the Korea National Health and Nutrition Examination Survey data between 2007 and 2020. @*Results@#In South Korea, the crude prevalence of hypercholesterolemia (total cholesterol ≥240 mg/dL or use of a lipid-lowering drug) in 2020 was 24%, and the age-standardized prevalence of hypercholesterolemia more than doubled from 2007 to 2020. The crude treatment rate was 55.2%, and the control rate was 47.7%. The crude prevalence of dyslipidemia (more than one out of three conditions [low-density lipoprotein-cholesterol ≥160 or the use of a lipid-lowering drug, triglycerides ≥200, or high-density lipoprotein-cholesterol (men and women) <40 mg/ dL]) was 40.2% between 2016 and 2020. However, it increased to 48.2% when the definition of hypo-high-density lipoprotein-cholesterolemia in women changed from <40 to <50 mg/dL. @*Conclusion@#Although the prevalence of hypercholesterolemia and dyslipidemia has steadily increased in South Korea, the treatment rate remains low. Therefore, continuous efforts are needed to manage dyslipidemia through cooperation between the national healthcare system, patients, and healthcare providers.
RESUMEN
Objective@#We aimed to assess the level of public awareness regarding dyslipidemia and its management among the Korean population. @*Methods@#We conducted a web- or mobile-based survey study targeting the general population, using various recruitment methods, between July 25, 2022 and August 26, 2022.The questionnaire consisted of 12 questions designed to collect demographic information and evaluate participants’ awareness and knowledge about dyslipidemia. @*Results@#In total, 2,882 participants who completed the survey were included in the analysis.Among the participants, a substantial majority (89.1%) were familiar with the concepts of “good cholesterol” and “bad cholesterol,” while a comparatively lower percentage (just 46.7%) were acquainted with the term “dyslipidemia.” Noticeable variations in understanding were observed when examining specific aspects of dyslipidemia management, including diet, exercise, and pharmacotherapy. @*Conclusion@#The results of this survey underscore the significance of enhancing public awareness about dyslipidemia within the context of health literacy, demonstrating the necessity for a more comprehensive approach that includes education and policymaking to effectively manage dyslipidemia.
RESUMEN
Background@#This study analyzed common gynecologic problems among Korean patients younger than ten years. @*Methods@#We performed a retrospective analysis of medical records of patients younger than ten years who visited the Pediatric and Adolescent Gynecology Clinic at Samsung Medical Center between 1995 and 2020. @*Results@#Among the 6,605 patients who visited the Pediatric and Adolescent Gynecology Clinic, data from 642 patients younger than ten years were analyzed in this study. The most common chief complaint was genital anomalies, followed by increased vaginal discharge and abnormal findings on clinical examinations. The most common disease entity was agglutination of the labia minora, which was commonly discovered incidentally during routine screenings. Vulvovaginitis, the second most common disease, was identified by symptoms of vaginal discharge, pruritus, and vaginal spotting. Neoplasm, issues with vaginal bleeding, and “other causes” were additional categories of gynecologic problems.245 patients (38.2%) were referred from primary care sources, 175 patients (27.4%) sought care directly at the clinic, 169 patients (26.3%) were referrals from the institution’s pediatric department, and the remainder were referrals from other departments. @*Conclusion@#This study provides information about the gynecologic problems most frequently encountered in pediatric patients. The study provides helpful insight for primary care physicians into the proper management and timing of referrals for these gynecologic problems of pediatric patients.
RESUMEN
Background@#With advance of next-generation sequencing (NGS) techniques, the need for mitochondrial DNA analysis is increasing not only in the forensic area, but also in medical fields. @*Methods@#Two commercial programs, Converge Software (CS) and Torrent Variant Caller for variant calling of NGS data, were compared with a considerable amount of sequence data of 50 samples with a homogeneous ethnicity. @*Results@#About 2,300 variants were identified and the two programs showed about 90% of consistency. CS, a dedicated analysis program for mitochondrial DNA, showed some advantages for forensic use. By additional visual inspection, several causes of discrepancy in variant calling results were identified. Application of different notation rules for mitochondrial sequence and the minor allele frequency close to detection threshold were the two most significant reasons. @*Conclusion@#With prospective improvement of each program, researchers and practitioners should be aware of characteristics of the analysis program they use and prepare their own strategies to determine variants.
RESUMEN
Background@#s: Fimasartan is the most recently developed, potent, and long-acting angiotensin II receptor blocker (ARB). However, data are limited regarding treatment effects of fimasartan in patients with heart failure. @*Methods@#Between 2010 and 2016, patients who underwent coronary revascularization for myocardial infarction (MI) with heart failure and prescription of ARB at hospital discharge were enrolled from the Korean nationwide medical insurance data. Clinical outcomes were compared between patients receiving fimasartan and those receiving other ARBs (candesartan, valsartan, losartan, telmisartan, olmesartan, and irbesartan). The primary outcome was a composite of all-cause death, recurrent MI, hospitalization for heart failure, and stroke. @*Results@#Of 2,802 eligible patients, fimasartan was prescribed to 124 patients (4.4%). During a median follow-up of 2.2 years (interquartile range, 1.0–3.9), 613 events of the primary outcome occurred. There was no significant difference in the primary outcome between patients receiving fimasartan and those receiving other ARBs (adjusted hazard ratio [HR], 0.82; 95% confidence interval [CI], 0.46–1.45). Compared with patients receiving other ARBs, those receiving fimasartan had comparable incidence of all-cause death (adjusted HR, 0.70; 95% CI, 0.30–1.63), recurrent MI (adjusted HR, 1.28; 95% CI, 0.49–3.34), hospitalization for heart failure (adjusted HR, 0.70; 95% CI, 0.27–1.84), and stroke (adjusted HR, 0.59; 95% CI, 0.18–1.96). @*Conclusion@#In this nationwide cohort, fimasartan, compared with other ARBs, had comparable treatment effects for a composite of all-cause death, recurrent MI, hospitalization for heart failure, and stroke in patients with heart failure after MI.
RESUMEN
The pediatric population with comorbidities is a high-risk group for severe coronavirus disease 2019 (COVID-19). As of January 2023, the COVID-19 vaccination rate for at least two doses among Korean children 5–11 years is low at 1.1%. We summarized the COVID-19 vaccination status for the pediatric population (5–17 years) with comorbidities through July 2022 using the National Health Insurance Service database. Pediatric patients with comorbidities had higher vaccination rates than the general pediatric population (2.4% vs. 1.1% in 5–11-year-olds [P < 0.001], 76.5% vs. 66.1% in 12–17-year-olds [P < 0.001]). However, there were substantial differences according to comorbidity category, and the 2-dose vaccination rate was lowest among children with immunodeficiency in all age groups (1.1% in 5–11-year-olds, 51.2% in 12–17-year-olds). The COVID-19 vaccination rate among Korean children has remained stagnant at a low proportion despite ongoing outreach. Thus, more proactive strategies are needed alongside continuous surveillance.
RESUMEN
Purpose@#This study was conducted to investigate the influence of grit and resilience on the retention intention of new nurses. @*Methods@#The participants were 148 new nurses who had worked at two tertiary hospitals for less than 12 months. The data were collected on self-reported questionnaires from October 25, 2022, to November 28, 2022. T-tests, one-way analysis of variance, Mann-Whitney U test, Kruskal-Wallis test, Spearman’s correlation analysis, and multiple regression were used to analyze the data. @*Results@#Retention intention was significantly different according to placement in the desired department and job satisfaction. Retention intention showed a significant positive correlation with grit (p<.001) and resilience (p<.001). Significant factors influencing the retention intention of new nurses were resilience (β=.30, p<.001), grit (β=.27, p=.001), and job dissatisfaction (β=-.16, p=.029). These variables accounted for 29% (F=21.41, p<.001) of new nurses’ retention intention. @*Conclusion@#The results of this study showed that considering these factors influencing the retention intention of new nurses might be helpful for strategies addressing nurse staffing challenges.
RESUMEN
Objectives@#To investigate the effect of commercially available hard seltzer on the tooth enamel surface. @*Methods@#Some commercially available hard seltzer were purchased at the market and the characteristics of the beverages were surveyed. Subsequently, Cloud hard seltzer mango was selected for the hard seltzer group (group 4), Jeju Samdasoo for the mineral water group (group 1), Coca-Cola for the cola group (group 2), and Cloud Original for the beer group (group 3). The specimens were immersed in the experimental beverage for 30 minutes, then the surface microhardness and surface condition of the specimens were evaluated. @*Results@#The average pH of the twelve types of hard seltzer in this study were 3.51±0.01 (before stirring) and 3.46±0.01 (after stirring). The pH of experimental beverage were 7.92±0.03 (group 1), 2.55±0.01 (group 2), 4.41±0.01 (group 3), and 3.31±0.01 (group 4). Paired t-test of the surface microhardness of enamel before and after beverage immersion found no significant difference in group 1 (P>0.05), but a significant difference was observed in groups 2, 3, and 4 (P<0.05). One way ANOVA of the surface microhardness change values (∆VHN, before - after immersion) among groups found a statistically significant difference between groups 1 and 3 (9.20±34.82 ∆VHN and 20.20±6.52 ∆VHN) and groups 2 and 4 (82.90±18.08 ∆VHN and 67.10±18.27 ∆VHN) (P<0.05).On scanning electron microscopy, hard seltzer group showed rough and ruined surface condition. @*Conclusions@#This study found a risk of dental erosion due to the low pH of hard seltzer. Therefore, it is suggested that when ingesting hard seltzer, dental erosion should be considered for oral health.
RESUMEN
Purpose@#This study aimed to investigate the impact of different types of complications on long-term survival following total gastrectomy for gastric cancer. @*Materials and Methods@#A total of 926 patients who underwent total gastrectomy between 2008 and 2016 were included. Patients were divided into the morbidity and no-morbidity groups, and long-term survival was compared between the 2 groups. The prognostic impact of postoperative morbidity was assessed using a multivariate Cox proportional hazard model, which accounted for other prognostic factors. In the multivariate model, the effects of each complication on survival were analyzed. @*Results@#A total of 229 patients (24.7%) developed postoperative complications. Patients with postoperative morbidity showed significantly worse overall survival (OS) (5-year, 65.0% vs. 76.7%, P<0.001) and cancer-specific survival (CSS) (5-year, 74.2% vs. 83.1%, P=0.002) compared to those without morbidity. Multivariate analysis adjusting for other prognostic factors showed that postoperative morbidity remained an independent prognostic factor for OS (hazard ratio [HR], 1.442; 95% confidence interval [CI], 1.136–1.831) and CSS (HR, 1.463; 95% CI, 1.063–2.013). There was no significant difference in survival according to the severity of complications. The following complications showed a significant association with unfavorable long-term survival: ascites (HR, 1.868 for OS, HR, 2.052 for CSS), wound complications (HR, 2.653 for OS, HR, 2.847 for CSS), and pulmonary complications (HR, 2.031 for OS, HR, 1.915 for CSS). @*Conclusions@#Postoperative morbidity adversely impacted survival following total gastrectomy for gastric cancer. Among the different types of complications, ascites, wound complications, and pulmonary complications exhibited significant associations with longterm survival.
RESUMEN
Background@#and Purpose All young males in South Korea must undergo a physical examination for their participation in military service. We aimed to determine the prevalence rate (PR) of various neuromuscular diseases in young South Korean males using the data of exempted patients and soldiers. @*Methods@#The number of males exempted based on specific items of physical examination corresponding to neuromuscular disease during 2011–2020 were obtained from the records of the Military Manpower Administration. The list of enlisted soldier patients who were discharged from military service due to neuromuscular diseases during 2011–2020 was obtained from the Armed Forces Medical Command, and their medical records were reviewed. @*Results@#The PR of neuromuscular diseases was calculated among 948 identified males: 713 exempted males and 235 soldiers. The PRs of overall hereditary neuropathies, Hirayama disease (HD), myasthenia gravis (MG), and inherited muscle diseases in South Korean males in their early 20s were 8.34 (95% confidence interval [CI], 7.39–9.30), 5.54 (95% CI, 4.76–6.32), 2.97 (95% CI, 2.40–3.55), and 10.38 (95% CI, 9.31–11.46) per 100,000 persons, respectively.Among the enlisted soldiers, hereditary neuropathy with liability to pressure palsy was the most common neuromuscular disease, with a prevalence among the enlisted soldiers of 3.11 (95% CI, 2.42–3.80) per 100,000 persons. Myotonic dystrophy was the most prevalent myopathy, followed by facioscapulohumeral muscular dystrophy. @*Conclusions@#The 10-year PRs of hereditary polyneuropathies, HD, MG, and inherited muscle diseases in young South Korean males have been reported. These data could be valuable to understanding each neuromuscular disease in the young male population of South Korea.
RESUMEN
Objective@#Several particular morphological factors that contribute to the hemodynamics of the anterior communicating artery (ACoA) have been documented, but no study has investigated the role of the degree of anterior cerebral artery (ACA) rotation on the presence of ACoA aneurysms (ACoAAs). @*Methods@#A retrospective study of an institutional aneurysm database was performed; patients with ruptured or nonruptured ACoAAs were selected. Two sex- and age-matched control groups were identified: control Group A (nonaneurysms) and control Group B (middle cerebral artery aneurysms). Measurements of ACA rotation degree were obtained by using a three-dimensional imaging tool. @*Results@#From 2015 to 2020, 315 patients were identified: 105 in the ACoAA group, 105 in control Group A, and 105 in control Group B. The average age at the time of presentation was 64 years, and 52.4% were female. The ACA rotation degree of the ACoAA group was significantly higher than that of control Group A (p <0.01). The A1 ratio and the A1A2 ratio of the ACoAA group were greater than those of control Group A (p <0.01 and p <0.01, respectively). The ACA rotation degree correlated insignificantly with aneurysm size in ACoAA patients (p=0.78). The ACA rotation degree in the ACoAA group was also insignificantly different from that in control B (p=0.11). @*Conclusions@#The degree of ACA rotation was greater in the ACoAA group than in the nonaneurysm group, and it may serve as an imaging marker for ACoAA.
RESUMEN
Intracranial dural arteriovenous fistulas (DAVF) are abnormal connections between intracranial arterial and venous systems within the dural layers. Intracranial DAVFs are rare but can occur wherever dural components exist. The pathogenesis of DAVFs is controversial. Venous hypertension is considered as a main cause of clinical symptoms which are subclassified into asymptomatic, benign and aggressive manifestations. To date, several classification schemes have been proposed to stratify the natural course and risks of DAVFs. Currently, endovascular therapy is the main treatment modality. Moreover, the use of radiosurgery and radiotherapy has been limited. Open surgery is also selectively performed as a main treatment modality for specific types of DAVFs and an adjunctive modality for the endovascular approach. Herein, we present a review of the general perspectives of intracranial DAVFs with an emphasis on the role of surgery.
RESUMEN
Preterm birth (PTB), a pregnancy-related disease, is defined as a birth before 37 weeks of gestation. It is a major cause of maternal mortality and morbidity worldwide, and its incidence rate is steadily increasing. Various genetic factors can contribute to the etiology of PTB. Vascular endothelial growth factor A (VEGFA) gene is an important angiogenic gene and its polymorphisms have been reported to be associated with PTB development. Therefore, we conducted a case-control study to evaluate the association between VEGFA rs699947, rs2010963, and rs3025039 polymorphisms and PTB in Korean women. A total of 271 subjects (116 patients with PTB and 155 women at ≥38 weeks of gestation) were analyzed in this study. The genotyping of VEGFA gene polymorphisms was performed using polymerase chain reaction– restriction fragment length polymorphism. No significant association between the patients with PTB and the control groups was confirmed. In the combination analysis, we found a significant association between PTB and VEGFA rs699947 CC-rs2010963 GG-rs3025039 CC combination (odds ratio, 3.77; 95% confidence interval, 1.091 to 13.032; p = 0.031). The VEGFA rs699947, rs2010963, and rs3025039 polymorphisms might have no genetic association with the pathogenesis of PTB in Korean women. However, the combination analysis indicates the possibility that VEGFA acts in PTB pathophysiology. Therefore, larger sample sets and replication studies are required to further elucidate our findings.
RESUMEN
Background/Aims@#Immunocompromised patients with acute colonic diverticulitis are at high risk for complications and failure of non-surgical treatment. However, evidence on the comparative outcomes of immunocompromised and immunocompetent patients with diverticulitis is lacking. This systematic review and meta-analysis investigated the outcomes of medical treatment in immunocompromised and immunocompetent patients with diverticulitis. @*Methods@#A comprehensive literature search was conducted in PubMed, Embase, and the Cochrane Library. Studies comparing the clinical outcomes of immunocompromised and immunocompetent patients with diverticulitis were included. @*Results@#A total of 10 studies with 1,946,461 subjects were included in the quantitative synthesis. The risk of emergency surgery and postoperative mortality after emergency surgery was significantly higher in immunocompromised patients than in immunocompetent patients with diverticulitis (risk ratio [RR], 1.76; 95% confidence interval [CI], 1.31–2.38 and RR, 3.05; 95% CI, 1.70–5.45, respectively). Overall risk of complications associated with diverticulitis was non-significantly higher in immunocompromised than in immunocompetent patients (RR, 1.24; 95% CI, 0.95–1.63). Overall mortality irrespective of surgery was significantly higher in immunocompromised than in immunocompetent patients with diverticulitis (RR, 3.65; 95% CI, 1.73–7.69). By contrast, postoperative mortality after elective surgery was not significantly different between immunocompromised and immunocompetent patients with diverticulitis. In subgroup analysis, the risk of emergency surgery and recurrence was significantly higher in immunocompromised patients with complicated diverticulitis, whereas no significant difference was shown in mild disease. @*Conclusions@#Immunocompromised patients with diverticulitis should be given the best medical treatment with multidisciplinary approach because they had increased risks of surgery, postoperative morbidity, and mortality than immunocompetent patients.
RESUMEN
Fibrodysplasia ossificans progressiva is a rare hereditary disorder characterized by progressive heterotopic ossifica-tion in muscle and connective tissue, with few reported cases affecting the head and neck region. Although plain radiographic findings and computed tomography features have been well documented, limited reports exist onmagnetic resonance findings. This report presents 2 cases of fibrodysplasia ossificans progressiva, one with limited mouth opening due to heterotopic ossification of the lateral pterygoid muscle and the other with restricted neck movement due to heterotopic ossification of the platysma muscle. Clinical findings of restricted mouth opening or limited neck movement, along with radiological findings of associated heterotopic ossification, should prompt consideration of fibrodysplasia ossificans progressiva in the differential diagnosis. Dentists should be particularly vigilant with patients diagnosed with fibrodysplasia ossificans progressiva to avoid exposure to diagnostic biopsy andinvasive dental procedures.
