ABSTRACT

Objective@#Cyclin-dependent kinase inhibitor (CDKN)2A/B homozygous deletion is a key molecular marker of isocitrate dehydrogenase (IDH)-mutant astrocytomas in the 2021 World Health Organization. We aimed to investigate whether qualitative and quantitative MRI parameters can predict CDKN2A/B homozygous deletion status in IDH-mutant astrocytomas. @*Materials and Methods@#Preoperative MRI data of 88 patients (mean age ± standard deviation, 42.0 ± 11.9 years; 40 females and 48 males) with IDH-mutant astrocytomas (76 without and 12 with CDKN2A/B homozygous deletion) from two institutions were included. A qualitative imaging assessment was performed. Mean apparent diffusion coefficient (ADC), 5th percentile of ADC, mean normalized cerebral blood volume (nCBV), and 95th percentile of nCBV were assessed via automatic tumor segmentation.Logistic regression was performed to determine the factors associated with CDKN2A/B homozygous deletion in all 88 patients and a subgroup of 47 patients with histological grades 3 and 4. The discrimination performance of the logistic regression models was evaluated using the area under the receiver operating characteristic curve (AUC). @*Results@#In multivariable analysis of all patients, infiltrative pattern (odds ratio [OR] = 4.25, p = 0.034), maximal diameter (OR = 1.07, p = 0.013), and 95th percentile of nCBV (OR = 1.34, p = 0.049) were independent predictors of CDKN2A/B homozygous deletion. The AUC, accuracy, sensitivity, and specificity of the corresponding model were 0.83 (95% confidence interval [CI], 0.72–0.91), 90.4%, 83.3%, and 75.0%, respectively. On multivariable analysis of the subgroup with histological grades 3 and 4, infiltrative pattern (OR = 10.39, p = 0.012) and 95th percentile of nCBV (OR = 1.24, p = 0.047) were independent predictors of CDKN2A/B homozygous deletion, with an AUC accuracy, sensitivity, and specificity of the corresponding model of 0.76 (95% CI, 0.60–0.88), 87.8%, 80.0%, and 58.1%, respectively. @*Conclusion@#The presence of an infiltrative pattern, larger maximal diameter, and higher 95th percentile of the nCBV may be useful MRI biomarkers for CDKN2A/B homozygous deletion in IDH-mutant astrocytomas.

ABSTRACT

Primary cutaneous anaplastic large cell lymphoma (C-ALCL) is a rare subtype of primary cutaneous lymphoma with a favorable prognosis. Primary cutaneous CD30+ lymphoproliferative disorders, which include C-ALCL and lymphomatoid papulosis, are the second most common group of cutaneous T-cell lymphomas. C-ALCL is comprised of large cells with anaplastic, pleomorphic, or immunoblastic cytomorphology, and indeed, more than 75% of the tumor cells express the CD30 antigen. C-ALCL clinically presents with solitary or localized reddish-brown nodules or tumors, and sometimes indurated papules, and they may be with ulceration covering with dark eschar. Multifocal lesions are seen in 20% of the patients. Extracutaneous dissemination, which mainly involves the regional lymph nodes, occurs in 10% of patients. A 69-year-old man noticed a mild elevated cutaneous lesion containing central ulceration covering with brownish black necrotic tissue on the right lower lip, and the lesion was surgically removed. After the first operation, another skin lesion was developed and the histological examination confirmed the diagnosis, C-ALCL. Eight specimens were excised during the 7-month follow-up period. The patient started the treatment with low-dose oral methotrexate (15 mg/wk) and there was no recurrence for 11 months.

ABSTRACT

Ehlers-Danlos syndrome (EDS) is an inherited disorder of collagen biosynthesis and structure, characterized by skin hyperextensibility, joint hypermobility, aberrant scars, and tissue friability. Besides the skin, skeleton (joint) and vessels, other organs such as the eyes and the intestine can be affected in this syndrome. Accordingly, interdisciplinary cooperation is necessary for a successful treatment. Three basic surgical problems are arising due to an EDS: decreased the strength of the tissue causes making the wound dehiscence, increased bleeding tendency due to the blood vessel fragility, and delayed wound healing period. Surgery patients with an EDS require an experienced surgeon in treating EDS patients; the treatment process requires careful tissue handling and a long postoperative care. A surgeon should also recognize whether the patient shows a resistance to local anesthetics and a high risk of hematoma formation. This report describes a patient with a wide open wound on the foot dorsum and delayed wound healing after the primary approximation of the wound margins.

ABSTRACT

BACKGROUND: Accurate mediastinal lymph node staging is vital for the optimal therapy and prognostication of patients with lung cancer. This study aimed to determine the preoperative risk factors for pN2 disease, as well as its incidence and long-term outcomes, in patients with clinical N0–1 non-small cell lung cancer. METHODS: We retrospectively analyzed patients who were treated surgically for primary non-small cell lung cancer from November 2005 to December 2014. Patients staged as clinical N0–1 via chest computed tomography (CT) and positron emission tomography (PET)-CT were divided into two groups (pN0–1 and pN2) and compared. RESULTS: In a univariate analysis, the significant preoperative risk factors for pN2 included a large tumor size (p=0.083), high maximum standard uptake value on PET (p<0.001), and central location of the tumor (p<0.001). In a multivariate analysis, central location of the tumor (p<0.001) remained a significant preoperative risk factor for pN2 status. The 5-year overall survival rates were 75% and 22.9% in the pN0–1 and pN2 groups, respectively, and 50% and 78.2% in the patients with centrally located and peripherally located tumors, respectively. In a Cox proportional hazard model, central location of the tumor increased the risk of death by 3.4-fold (p<0.001). CONCLUSION: More invasive procedures should be considered when pre-operative risk factors are identified in order to improve the efficacy of diagnostic and therapeutic plans and, consequently, the patient’s prognosis.

ABSTRACT

BACKGROUND: When a skin defect occurs, clinicians must work to restore the original skin quality as soon as possible. Accordingly, an artificial dermis can be used to supplement the wound and prevent severe scar contracture formation. The Terudermis is an artificial dermis that is simple and easy to use. We investigated the effectiveness of the Terudermis in the treatment of facial skin defects by analyzing previous relevant cases treated in our institution. METHODS: We retrospectively examined 143 patients who were treated with the Terudermis graft in facial skin defect at Dong Kang General Hospital in 2015 and 2016. The patients’ age, sex and location, wound size, complications were analyzed. In addition, the patients were asked to complete a self-satisfaction questionnaire after 18 months from the completion of treatment. The results were compared with that of autologous full-thickness skin graft (FTSG) and split-thickness skin graft (STSG) patients in same period. RESULTS: The mean self-satisfaction scores evaluated by patients were 4.1±1.0, 4.0±1.3 and 3.5±1.8 for the Terudermis graft, FTSG and STSG patients, respectively. With respect to complications, there were fewer incidences of hematoma, partial skin loss and complete skin loss in the Terudermis graft patients. CONCLUSION: In the present study, the Terudermis, when used to treat post-traumatic facial skin defects, is a good alternative option to obtain satisfactory aesthetic outcomes. Also, the Terudermis grafting is a simple and easy treatment method to perform.

ABSTRACT

BACKGROUND: Nasal bone fracture is one of the most common facial bone fracture types, and the surgical results exert a strong influence on the facial contour and patient satisfaction. Preventing secondary deformity and restoring the original bone state are the major goals of surgeons managing nasal bone fracture patients. In this study, a treatment algorithm was established by applying the modified open reduction technique and postoperative care for several years. METHODS: This article is a retrospective chart review of 417 patients who had been received surgical treatment from 2014 to 2015. Using prepared questionnaires and visual analogue scale, several components (postoperative nasal contour; degree of pain; minor complications like dry mouth, sleep disturbance, swallowing difficulty, conversation difficulty, and headache; and degree of patient satisfaction) were evaluated. RESULTS: The average scores for the postoperative nasal contour given by three experts, and the degree of patient satisfaction, were within the “satisfied” (4) to “very satisfied” (5) range (4.5, 4.6, 4.5, and 4.2, respectively). The postoperative degree of pain was sufficiently low that the patients needed only the minimum dose of painkiller. The scores for the minor complications (dry mouth, sleep disturbance, swallowing difficulty, conversation difficulty, headache) were relatively low (36.4, 40.8, 65.2, 32.3, and 34 out of the maximum score of 100, respectively). CONCLUSION: Satisfactory results were obtained through the algorithm-oriented management of nasal bone fracture. The degree of postoperative pain and minor complications were considerably low, and the degree of satisfaction with the nasal contour was high.

ABSTRACT

BACKGROUND: Packing after closed reduction of nasal fracture causes uncomfortable nasal obstruction in patients. We packed the superior meatus with synthetic polyurethane foam (SPF) to support the nasal bone, and packed the middle nasal meatus with a nasal airway splint (NAS) and SPF. The aim of this article is prospectively to compare the subjective patient discomfort of SPF (Nasopore Forte plus) packing alone and SPF with NAS. METHODS: We compared the prospectively subjective patient discomfort of SPF packing alone (group A) and SPF with NAS (group B) via visual analog scale (VAS; 0, no symptom; 100, most severe symptom). RESULTS: At first postoperative day group B showed significant lower scores in dry mouth, sleep disturbance, conversation difficulty. However at third postoperative day, VAS scores of each group had no statistically significant differences. Moreover at fifth postoperative day group A had statistically significant lower scores for nasal pain, dry mouth than the group B. CONCLUSION: Combination method of using NAS and SPF have some advantage on the patient comfort from first postoperative day to third postoperative day.

ABSTRACT

Postraumatic lung hernia is a rare occurrence. A number of cases reported in the literature have been treated with early thoracotomy to repair partial protruded lung and pleura to prevent strangulation and incarceration. We present a case of a 45-year-old patient of left posttrumatic lung hernia, in which closed digital reduction was successful. The strategy of the management approach could be established by further accumulated experience.

ABSTRACT

BACKGROUND: The up-regulation of the nitric oxide (NO)-cGMP pathway might be involved in the change of vascular reactivity in rats 3 days after they suffer acute myocardial infarction. However, the underlying mechanism for this has not been clarified. MATERIAL AND METHOD: Acute myocardial infarction (AMI) was induced by occluding the left anterior descending coronary artery (LAD) for 30 min (Group AMI), whereas the sham-operated control rats were treated similarly without LAD occlusion (Group SHAM). The concentration-response relationships for phenylephrine (PE), KCl, acetylcholine (Ach) and sodium nitroprusside (SNP) were determined in the endothelium intact E(+) and endothelium denuded E(-) thoracic aortic rings from the rats 3 days after AMI or a SHAM operation. The concentration-response relationships of PE in the E(+) rings from the AMI rats were compared with those relationships in the rings pretreated with nitric oxide synthase (NOS) inhibitor N omega-nitro-L-arginine methyl ester (L-NAME) or the cyclooxygenase inhibitor indomethacin. The plasma nitrite/nitrate concentrations were checked via a Griess reaction. The cyclic GMP content in the thoracic aortic rings was measured by radioimmunoassay and the endothelial nitric oxide synthase (eNOS) mRNA expression was assessed by real time PCR. RESULT: The mean infarct size (%) in the rats with AMI was 21.3+/-0.62%. The heart rate and the systolic and diastolic blood pressure were not significantly changed in the AMI rats. The sensitivity of the contractile response to PE and KCl was significantly decreased in both the E(+) and E(-) aortic rings of the AMI group (p<0.05). L-NAME completely reversed these contractile responses whereas indomethacin did not (p<0.05). Moreover, the sensitivity of the relaxation response to Ach was also significantly decreased in the AMI group (p<0.05). The plasma nitrite and nitrate content (p<0.05), the basal cGMP content (p<0.05) and the eNOS mRNA expression (p=0.056) in the AMI rats were increased as compared with the SHAM group. CONCLUSION: Our findings indicate that the increased eNOS activity and the up-regulation of the NO-cGMP pathway can be attributed to the decreased contractile or relaxation response in the rat thoracic aorta 3 days after AMI.

ABSTRACT

BACKGROUND: Several trials have reported on whether adjuvant chemotherapy for resected stage IB non-small cell lung cancer is needed. The aim of our study was to investigate prognostic factors for recurrence to help identify patients who should receive adjuvant chemotherapy. MATERIAL AND METHOD: We reviewed the cases of 48 stage IB non-small cell lung cancer patients between 1997 and 2006. Disease-free survival and overall survival rates were calculated by the Kaplan-Meier method. Univariate analysis was performed with the log rank test and multivariate analysis was done using Cox's proportional hazard model. RESULT: The median follow-up time was 48 months. The overall survival rate was 55.9%, and the disease-free survival rate was 48.6%. Of 8 variables, two factors, visceral pleural invasion and lymphovascular invasion, were prognostic factors of disease-free survival (univariate analysis). Visceral pleural invasion was a significant prognostic factor in multivariate analysis, and overall survival in compared one or more variable such as visceral pleural invasion or, and lymphovascular invasion with the other variables. CONCLUSION: Visceral pleural invasion was identified as a poor prognostic factor and it may help select which patients will benefit from adjuvant chemotherapy in addition to more comprehensive follow-up.

ABSTRACT

Intrathoracic goiters consist of two types: the primary and secondary type. Primary intrathoracic goiters are very rare. We report here on a case that was resected with using the thoracoscopic assist technique. The transthoracic or transsternal approach is necessary for primary goiters to remove them completely without complications.

ABSTRACT

Infection occurs very rarely in the sternoclavicular joint compared to other joints in the body. It occurs mainly in IV drug abusers, diabetics, chronic renal failure patients, septic patients and those with central vein catheters. In the early phase, it can be treated simply by antibiotics or incision, and drainage. However, when proper treatment is not begun early, bone destruction can occur, and only en-bloc resection of the involved bone can cure it. To reduce the risk of recurrence, we advanced a pectoralis major flap into the resected area based on the feeding artery. We report a case of a patient with sternoclavicular osteomyelitis who was successfully treated using en-bloc resection and a pectoral advancement flap.

ABSTRACT

BACKGROUND: Arterial grafts have been used to achieve better long-term results for coronary revascularization. Bilateral internal thoracic artery (ITA) grafts have a better results, but it may be not used in some situations such as diabetes and chronic obstructive pulmonary disease (COPD). We evaluated the clinical and angiographic results of composite left internal thoracic artery-radial artery (LITA-RA) Y graft. MATERIAL AND METHOD: Between April 2002 and September 2004, 119 patients were enrolled in composite Y graft for coronary bypass surgery. The mean age was 62.6+/-8.8 years old and female was 34.5%. Preoperative cardiac risk factors were as follows: hypertension 43.7%, diabetes 33.6%, smoker 41.2%, and hyperlipidemia 22.7%. There were emergency operation (14), cardiogenic shock (6), left ventricle ejection fraction (LVEF) less than 40% (17), and 17 cases of left main disease. Coronary angiography was done in 35 patients before the hospital discharge. RESULT: The number of distal anastomoses was 3.1+/-0.91 and three patients (2.52%) died during hospital stay. The off-pump coronary artery bypass (OPCAB) was applied to 79 patients (66.4%). The LITA was anastomosed to left anterior descending system except three cases which was to lateral wall. The radial Y grafts were anastomosed to diagonal branches (4), ramus intermedius (21), obtuse marginal branches (109), posterolateral branches (12), and posterior descending coronary artery (8). Postoperative coronary angiography in 35 patients showed excellent patency rates (LITA 100%,and RA 88.5%; 3 RA grafts which anastomosed to coronary arteries <70% stenosed showed string sign with competitive flow). CONCLUSION: The LITA-RA Y composite graft provided good early clinical and angiographic results in multivessel coronary revascularization. But it should be cautiously used in selected patients.

ABSTRACT

A 39-year-old man presented with a esophageal submucosal tumor on regular check up examination. Preoperative exams showed the typical submucosal tumor as leiomyoma and operative procedure was enucleation for complete resection. Postoperative pathologic diagnosis including histologic and immunohistochemical study was compatible with plexiform schwannoma. Plexiform schwannoma is one of the least common variant of schwannoma that typically shows a plexiform or multinodular pattern. To our knowledge, there is rare case report of plexiform schwannoma originating in the esophagus and we report one case with related literature.
