RESUMO
Objective@#This study aimed to develop and validate a comprehensive self-report questionnaire to assess emotional and behavioral problems and psychological trauma in maltreated children. @*Methods@#The Mental Health Scale for Maltreated Children (MHS-MC) was constructed to encompass five major symptoms (depression, anxiety, inattention/hyperactivity/impulsivity, aggression/defiance, and psychological trauma) prevalent in maltreated children. Critical items and ego-resilience subscale were also devised to increase clinical utility. After informed consent, 205 children (maltreated children, n=157, 76.6%) were recruited nationwide, and they answered a package of self-report measures, including the MHS-MC. Reliability, construct validity, concurrent validity, and criterion-related validity were examined to explore the psychometric properties. @*Results@#The reliability was good to excellent. Confirmatory factor analysis yielded a five-factorial solution for the symptom subscales supporting construct validity. In logistic regression, the total scores of the MHS-MC predicted membership in the maltreated group. Criterion-related validity was generally satisfactory in that all subscales of the MHS-MC showed significant correlations with relevant measures in the expected direction. @*Conclusion@#This is the first attempt to develop a comprehensive psychological scale based on nationwide data collected from maltreated Korean children. We hope that the continued standardization of this scale will contribute to evidence-based clinical and policy decisionmaking for maltreated children.
RESUMO
Background@#The importance of molecular pathology tests has increased during the last decade, and there is a great need for efficient training of molecular pathology for pathology trainees and as continued medical education. @*Methods@#The Molecular Pathology Study Group of the Korean Society of Pathologists appointed a task force composed of experienced molecular pathologists to develop a refined educational curriculum of molecular pathology. A 3-day online educational session was held based on the newly established structure of learning objectives; the audience were asked to score their understanding of 22 selected learning objectives before and after the session to assess the effect of structured education. @*Results@#The structured objectives and goals of molecular pathology was established and posted as a web-based interface which can serve as a knowledge bank of molecular pathology. A total of 201 pathologists participated in the educational session. For all 22 learning objectives, the scores of self-reported understanding increased after educational session by 9.9 points on average (range, 6.6 to 17.0). The most effectively improved items were objectives from next-generation sequencing (NGS) section: ‘NGS library preparation and quality control’ (score increased from 51.8 to 68.8), ‘NGS interpretation of variants and reference database’ (score increased from 54.1 to 68.0), and ‘whole genome, whole exome, and targeted gene sequencing’ (score increased from 58.2 to 71.2). Qualitative responses regarding the adequacy of refined educational curriculum were collected, where favorable comments dominated. @*Conclusions@#Approach toward the education of molecular pathology was refined, which would greatly benefit the future trainees.
RESUMO
Purpose@#We aimed to identify factors influencing smoking cessation success among cancer patients registered in an inpatient smoking cessation program at a single cancer center. @*Materials and Methods@#The electronic medical records of enrolled patients with solid cancer were retrospectively reviewed. We evaluated factors associated with 6-month smoking cessation. @*Results@#A total of 458 patients with cancer were included in this study. Their mean age was 62.9±10.3 years, and 56.3% of the participants had lung cancer. 193 (42.1%) had not yet begun their main treatment. The mean number of counseling sessions for the participants was 8.4±3.5, and 46 (10.0%) patients were prescribed smoking cessation medications. The 6-month smoking cessation success rate was 48.0%. Multivariate analysis showed that younger age (<65 years), cohabited status, early stage, and the number of counseling sessions were statistically significant factors affecting 6-month smoking cessation success (p<0.05). Initiation of a cessation program before cancer treatment was significantly associated with cessation success (odds ratio, 1.66; 95% confidence interval, 1.02–2.70; p=0.040). @*Conclusion@#Smoking cessation intervention must be considered when establishing a treatment plan immediately after a cancer diagnosis among smokers.
RESUMO
Background@#An association between environmental pollutants and alcohol-related liver disease (ALD) has not been determined until now. The objectives of this study were to examine the association of the pollutants with ALD, and whether the pollutants together increased the risk of ALD. @*Methods@#Data were extracted from the Korea National Health and Nutrition Examination Survey (2010–2013 and 2016–2017; n = 11,993). Blood levels of lead, cadmium, and mercury were measured. ALD was defined by a combination of excessive alcohol consumption and ALDon-alcoholic fatty liver disease index > 0. The aspartate aminotransferase-to-platelet ratio index and fibrosis (FIB)-4 score were used to evaluate ALD FIB. @*Results@#The odds ratios (ORs) of ALD for the highest versus the lowest quartiles of exposure were for lead, 7.39 (95% confidence interval [CI], 5.51–9.91); cadmium, 1.68 (95% CI, 1.32–2.14); and mercury, 5.03 (95% CI, 3.88–6.53). Adjusting for age, gender, smoking, occupation, education, and personal income attenuated the associations but indicated significant positive trends (all P trend < 0.001). A positive additive interaction between cadmium and lead was observed. The relative excess OR due to the interaction was 0.96 (95% CI, 0.41–1.51); synergy index = 2.92 (95% CI, 0.97–8.80). Among 951 subjects with ALD, advanced FIB was associated with lead and cadmium (OR, 3.46, 95% CI, 1.84–6.53; OR, 8.50, 95% CI, 2.54–28.42, respectively), but not with mercury. The effect estimates for lead and cadmium remained significant even after adjustment for daily alcohol intake. @*Conclusion@#Blood levels of lead, cadmium, and mercury were significantly associated not only with the risk of ALD but also with ALD FIB. Cadmium and lead have synergistic effects that increase the risk of ALD.
RESUMO
Objective@#This study examined whether the efficiency of the level of detection (LOD) and upper reference limit (URL) for high-sensitivity cardiac troponin I (hs-cTnI) is increased when major adverse cardiovascular events (MACEs) occur in patients with low-risk chest pain who visit the emergency department (ED) and how long they stay in the ED. @*Methods@#The URL for hs-cTnI used in the hospital improved from 0.04 ng/mL (LOD <0.0041 ng/mL) in 2018 to 19.8 pg/mL (LOD <2.3 pg/mL) in 2019. In these two years, the occurrence of MACEs, frequency of hs-cTnI follow-up in the ER, and the length of stay in the ER were compared. In addition, the three calculated risk assessment scores for the safety level of early discharge were compared. @*Results@#In 2018, there were six MACEs out of 120 patients (5.0%), no cardiac deaths, one acute myocardial infarction (AMI), and five unplanned coronary revascularizations. In 2019, six MACEs out of 105 patients (5.7%) were all unplanned coronary revascularizations without any cardiac deaths or AMIs. @*Conclusion@#Although the level of hs-cTnI measurement was improved, there was no difference in the incidence of MACEs in patients with low-risk chest pain who were discharged from the ED, and the number of hs-cTnI follow-ups and time in the ED increased. Interestingly, there were only short-term MACEs and no medium-term MACEs. In addition, there was little to no coronary artery occlusion disease. The risk assessment score combined with hs-cTnI improved the predictive performance for MACEs.
RESUMO
Peripheral scalp T-cell lymphoma is a very rare disease. We report a case of a 22-year-old man who presented an indolent large scalp mass in the right frontal scalp region. The patient’s physical examination demonstrated no palpable mass in the chest, abdomen, and extremities. The brain CT revealed a high-density large scalp mass of the subgaleal layer in the right frontal and a small scalp mass of the subgaleal layer in the left frontal. The brain MRI showed multifocal enhancing masses in the bilateral dura, the subgaleal layer of the scalp, and the skull. The patient underwent removal of the tumor found in the right frontal scalp. The histologic diagnosis was peripheral T-cell lymphoma. Bone marrow aspiration showed the involvement of T-cell lymphoma. The patient received chemotherapy with cyclophosphamide, vincristine, doxorubicin, and prednisolone (CHOP protocol) for 3 cycles. The patient was discharged without neurological deficit. The patient showed no evidence of recurrence 15 months after surgery. We report a rare case of peripheral T-cell lymphoma mimicking benign scalp tumors.
RESUMO
Rosai–Dorfman Disease (RDD) is a rare lymphoproliferative disease, and the occurrence of isolated intracranial RDD is extremely rare. Most cases of intracranial RDDs present as dural masses showing homogenous enhancement on MRI, which makes it difficult to differentiate these masses from meningiomas before surgery unless massive cervical lymphadenopathy is observed. We herein report a rare case of isolated intracranial RDD in a 65-year-old male. Brain MRI revealed a well-defined enhancing mass-like lesion involving the right frontal convexity and subtle diffusion restriction. However, only a subtle blush was observed on the preoperative cerebral angiogram. Although instances of isolated intracranial RDD are rare, it should be considered as a potential differential diagnosis when a dural mass with hypovascularity is visualized on the cerebral angiogram.
RESUMO
Hereditary spherocytosis is the most common hereditary red blood cell membrane disorder. It results from a deficiency in certain proteins that are part of the red blood cell membrane cytoskeleton. We report a case of adrenal myelolipoma in a 23-yearold patient with hereditary spherocytosis. She was diagnosed with hereditary spherocytosis at 7 months of age. As she grew older, hemoglobin level was low, so splenectomy was recommended, but continuous follow up was not possible due to the circumstances of the patient, so the splenectomy was delayed. Adrenal myelolipoma was discovered incidentally at the age of 23 with abdominal pain and cholecystitis with gallstones at the time. Myelolipoma is a benign tumor of the mesenchymal origin;its etiology remains unclear. Myelolipoma is composed of adipose and hematopoietic tissues and mainly arises from adrenal tissues. The mass is often detected during routine radiologic examinations because myelolipoma is usually asymptomatic and not generally associated with hematologic diseases. The prevalence of myelolipoma appears to be increasing due to the increased use of imaging modalities. The association of myelolipoma with hereditary spherocytosis has rarely been reported in the literature. To our best knowledge, this is the first report of adrenal myelolipoma associated with hereditary spherocytosis in the Korean population.
RESUMO
Post-partum galactocele is a common benign disease among breastfeeding women, whereas retromammary and peri-implant galactocele are relatively rare conditions. Herein, a 34-yearold, 1 month-postpartum female, who had augmentation mammoplasty and a 1-month history of breast pump use, presented with left breast enlargement for 2 weeks. An initial left breast US revealed hyperechoic peri-implant fluid collection. Additional US-guided fine needle aspiration was done using a 21G-needle, draining the milk component in the process, and cytologic results revealed numerous crystals, suggestive of galactocele. Various diseases, especially breast implant-associated anaplastic large cell lymphoma, can cause peri-implant fluid collection in an augmented breast. Thus, correlating imaging features with clinical information and cytologic analysis plays an important role in appropriate management.
RESUMO
Malignant lymphoma is a tumor of the immune system. It mainly occurs in the lymph node, but it can also originate from extranodal organs such as the gastrointestinal tract, salivary gland and the sinonasal tract. A primary malignant lymphoma in the paranasal sinuses is rare and usually occurs in the maxillary or ethmoid sinus. The sphenoid sinus is a rare primary site for extranodal lymphomas. Moreover, follicular lymphoma involving paranasal sinuses rarely occurs. Recently, we experienced a patient who complained of facial swelling, exophthalmos, reduced visual acuity, and diplopia for a month, and she was diagnosed with follicular lymphoma of the sphenoid sinus and orbit. Here we report a rare case of follicular lymphoma of the sphenoid sinus and orbit, along with a literature review.
RESUMO
Ceruminous glands are specialized sudoriferous glands located in the external auditory canal (EAC). Tumors originating from these ceruminous glands are rare lesions of EAC; in particular, syringocystadenoma papilliferum (SCAP) is an extremely rare ceruminous glands neoplasm to occur in the EAC. Although it is rare, the association of SCAP with tubular apocrine adenoma in the background of nevus sebaceous on the body, extremities, and scalp is well documented. In this article, we report on a 60-year-old male who presented a mass in EAC, which was surgically removed. The final diagnosis of SCAP was determined by histological analysis and the patient has been well without recurrence.
RESUMO
Although the understanding of appendiceal mucinous neoplasms (AMNs) and their relationship with disseminated peritoneal mucinous disease have advanced, the diagnosis, classification, and treatment of AMNs are still confusing for pathologists and clinicians. The Gastrointestinal Pathology Study Group of the Korean Society of Pathologists (GPSG-KSP) proposed a multicenter study and held a workshop for the “Standardization of the Pathologic Diagnosis of the Appendiceal Mucinous Neoplasm” to overcome the controversy and potential conflicts. The present article is focused on the diagnostic criteria, terminologies, tumor grading, pathologic staging, biologic behavior, treatment, and prognosis of AMNs and disseminated peritoneal mucinous disease. In addition, GPSG-KSP proposes a checklist of standard data elements of appendiceal epithelial neoplasms to standardize pathologic diagnosis. We hope the present article will provide pathologists with updated knowledge on how to handle and diagnose AMNs and disseminated peritoneal mucinous disease.
RESUMO
Objective@#The use of a high flow nasal cannula (HFNC) might cover the gap between conventional oxygen therapy andmechanical ventilation in the management of acute respiratory failure patients and could be a significant factor in determiningpatient outcomes. Early predictors of HFNC failure may help a clinician decide whether to shift the patient to amechanical ventilator. We aimed at identifying the predictors associated with HFNC failure and the application of amechanical ventilator using arterial blood gas analysis (ABGA). @*Methods@#We retrospectively analyzed patients who were admitted to the emergency room at a single center with respiratorydistress and a PaO2/FiO2 ratio (ratio of arterial partial pressure of oxygen to fraction of inspired oxygen) of less than300. Comparing keeping and weaning HFNC groups with the escalation group, we sought to identify a few discriminatingfactors. Initial ABGA was done when the patients entered the emergency room and this was followed up within 2 hoursafter HFNC therapy. @*Results@#Two hundred and eighteen patients were enrolled and of these HFNC therapy succeeded in 153 and failed in65. At baseline Glasgow Coma Scale, follow-up (F/U) pH, ΔpH, and F/U respiratory rate-oxygenation index were lowerand pro-brain natriuretic peptide, initial lactate, F/U lactate, ΔPCO2, heart rate, acidosis, consciousness, oxygenation,respiratory rate score, Acute Physiology And Chronic Health Evaluation score, Simplified Acute Physiology Score, andSequential Organ Failure Assessment score were significantly higher in the HFNC failure group. The results of the multivariateanalysis indicated that initial lactate (odds ratio [OR], 1.215; 95% confidence interval [CI], 1.081-1.366; P=0.001)and ΔpH (OR, 0.000; 95% CI, 0.000-0.018; P<0.001) were independently associated with the prediction of application ofthe mechanical ventilator. @*Conclusion@#Patients who had higher initial lactate levels and insufficiently corrected pH after HFNC therapy may needto be monitored carefully and escalation of oxygen therapy may need to be considered.

RESUMO
Myeloid sarcoma is characterized by the presence of myeloid blasts at an extramedullar site that disrupts the normal architecture of the organ. Many of these cases are associated with acute myeloid leukemia, chronic myeloid leukemia, myelodysplastic syndrome, or occur in de novo. It occurs most commonly in skin, lymph node, gastrointestinal tract, bone, soft tissue but, rarely in head and neck; especially in nasal cavity. Therefore, it is often misdiagnosed as a different disease: most commonly as lymphoma. Here we report a rare case of myeloid sarcoma in the nasal cavity that occurred in a patient with leukemic transformation with myelodysplastic syndrome, provided with literature review.
RESUMO
Herein, we report a case of synchronous bilateral triple negative invasive ductal breast carcinoma in a patient with discrepant pathologic response to neoadjuvant chemotherapy. Right and left breast cancer stages at the initial diagnosis were T1cN0M0 and T4dN3aM0, respectively. The patient was identified as a BRCA1 mutation carrier and treated with four cycles of adriamycin and cyclophosphamide, followed by four cycles of docetaxel. Bilateral breast cancer stages decreased with the first regimen. However, the bilateral breast cancers showed discrepant responses to chemotherapy with docetaxel. The right breast cancer showed a continuous tumor volume reduction while the left breast cancer showed marked progression. Finally, the tumor size was 0.3 cm and 12 cm in the right and left mastectomy specimens, respectively. As bilateral breast cancers of the same subtype may show discrepant responses to neoadjuvant chemotherapy, close monitoring and follow-up imaging are required to avoid delayed surgery.

RESUMO
We report herein a 46-year-old woman who presented with mucinous breast carcinoma that appeared as a coarse and densely calcified mass on mammography. The lesion was a 4.6-cmsized palpable, hyperechoic, calcified mass with posterior shadowing on ultrasonography. This finding is a unique feature of mucinous breast carcinoma and is also observed in unusual breast cancer variants such as metaplastic breast cancer with chondroid differentiation, extraosseous osteosarcoma, and breast chondrosarcoma. The lesion showed a slow-growing pattern throughout the 4-year observation period. Mammography performed 4 years ago revealed faint, grouped microcalcifications; the lesion increased in size over 2 years, presenting as a well-circumscribed, calcified mass, mimicking dystrophic calcification. As several unusual variants of breast cancer, including mucinous carcinoma, may present as coarse and densely calcified masses on mammography, immediate biopsy should be considered when they are observed.
RESUMO
Background/Aims@#Data on the trends in the prevalence of chronic liver disease (CLD) in Korea are scarce. This study aimed to evaluate whether the CLD prevalence changed between 1998–2001 and 2016–2017. @*Methods@#Data were extracted from the Korea National Health and Nutrition Examination Survey (1998–2001 to 2016– 2017; n=25,893). Non-alcoholic fatty liver disease (NAFLD) was defined as a hepatic steatosis index >36 in the absence of any other evidence of CLD. The definition of alcohol-related liver disease (ALD) was excessive alcohol consumption (≥210 g/week for men and ≥140 g/week for women) and an ALD/NAFLD index >0. @*Results@#The prevalence of NAFLD increased from 18.6% (95% confidence interval [CI], 17.8–19.5%) in 1998–2001 to 21.5% (95% CI, 20.6–22.6%) in 2016–2017. During the same time period, increases were observed in the prevalence of obesity (27.0 vs. 35.1%), central obesity (29.4 vs. 36.0%), diabetes (7.5 vs. 10.6%), and excessive drinking (7.3 vs. 10.5%). ALD prevalence also increased from 3.8% (95% CI, 3.4–4.2%) to 7.0% (95% CI, 6.4–7.6%). In contrast, chronic hepatitis B decreased from 5.1% (95% CI, 4.6–5.5%) to 3.4% (95% CI, 3.0–3.8%). The prevalence of chronic hepatitis C was approximately 0.3% in 2016–2017. @*Conclusions@#The prevalence of NAFLD and ALD increase among Korean adults. Our results suggest potential targets for interventions to reduce the future burden of CLD.
