ABSTRACT

Background@#Inverted follicular keratosis (IFK) is a benign tumor that occurs mainly as a single lesion in the head and neck. Histologically, the tumor lobules show endophytic or exophytic growth and are characterized by squamous eddies. IFK should be differentiated from seborrheic keratosis, verruca vulgaris, and squamous cell carcinoma (SCC).In particular, differentiating from well-differentiated SCC can be difficult when downward growth is observed along with some mitotic figures and inflammatory cell infiltration. @*Objective@#To evaluate and compare the clinical and histopathological characteristics of IFK and well-differentiated SCC. @*Methods@#We retrospectively reviewed the clinicopathological records of 21 patients diagnosed with IFK and 21 randomly assigned patients diagnosed with well-differentiated SCC between 2000 and 2022 at the Dermatology Department of the Yeungnam University Medical Center. @*Results@#IFK occurs frequently on the head and neck of middle aged and older adults, and its average size is less than 1 cm. Acantholysis was observed in varying degrees in IFK; however, well-differentiated SCC was mostly absent (17 cases) or mild (three cases) showing a statistically significant difference. Squamous eddies were observed in 21 cases of IFK and eight of well-differentiated SCC. The average number of dyskeratotic cells and mitotic counts did not differ significantly between IFK and well-differentiated SCC. @*Conclusion@#We suggested some evidence for the irritant origin of IFK. We also compared the clinicohistological findings of IFK with those of well-differentiated SCC and concluded that excluding atypical cells, abnormal mitotic figures, and irregular invasive borders is important for differential diagnosis.

ABSTRACT

Quetiapine is an atypical antipsychotic drug that can cause sinus tachycardia, hypotension, coma, etc. with overdose, and rarely convulsions, rhabdomyolysis and neuroleptic malignant syndrome. Posterior reversible encephalopathy syndrome usually occurs in association with hypertension, but can occur rarely in rhabdomyolysis accompanied by acute kidney injury and arginine vasopressin axis hyperstimulation. We report the experience of a patient hospitalized with a quetiapine overdose who developed drug-induced rhabdomyolysis and reversible encephalopathy without hypertension after acute renal injury.

ABSTRACT

Background@#Although coronavirus disease 2019 (COVID-19) is a viral infection, antibiotics are often prescribed due to concerns about accompanying bacterial infection. Therefore, we aimed to analyze the number of patients with COVID-19 who received antibiotic prescriptions, as well as factors that influenced antibiotics prescription, using the National Health Insurance System database. @*Methods@#We retrospectively reviewed claims data for adults aged ≥ 19 years hospitalized for COVID-19 from December 1, 2019 to December 31, 2020. According to the National Institutes of Health guidelines for severity classification, we calculated the proportion of patients who received antibiotics and the number of days of therapy per 1,000 patient-days. Factors contributing to antibiotic use were determined using linear regression analysis. In addition, antibiotic prescription data for patients with influenza hospitalized from 2018 to 2021 were compared with those for patients with COVID-19, using an integrated database from Korea Disease Control and Prevention Agency-COVID19-National Health Insurance Service cohort (K-COV-N cohort), which was partially adjusted and obtained from October 2020 to December 2021. @*Results@#Of the 55,228 patients, 46.6% were males, 55.9% were aged ≥ 50 years, and most patients (88.7%) had no underlying diseases. The majority (84.3%; n = 46,576) were classified as having mild-to-moderate illness, with 11.2% (n = 6,168) and 4.5% (n = 2,484) having severe and critical illness, respectively. Antibiotics were prescribed to 27.3% (n = 15,081) of the total study population, and to 73.8%, 87.6%, and 17.9% of patients with severe, critical, and mild-to-moderate illness, respectively. Fluoroquinolones were the most commonly prescribed antibiotics (15.1%; n = 8,348), followed by third-generation cephalosporins (10.4%; n = 5,729) and beta-lactam/beta-lactamase inhibitors (6.9%; n = 3,822). Older age, COVID-19 severity, and underlying medical conditions contributed significantly to antibiotic prescription requirement. The antibiotic use rate was higher in the influenza group (57.1%) than in the total COVID-19 patient group (21.2%), and higher in severe-to-critical COVID-19 cases (66.6%) than in influenza cases. @*Conclusion@#Although most patients with COVID-19 had mild to moderate illness, more than a quarter were prescribed antibiotics. Judicious use of antibiotics is necessary for patients with COVID-19, considering the severity of disease and risk of bacterial co-infection.

ABSTRACT

Background@#Nodular hidradenoma is a relatively common benign cutaneous neoplasm, which usually presents as solitary intradermal nodule. In Korea, an extensive study on tumors with eccrine differentiation was performed in 2006; however, the study considered all eccrine tumors and detailed analysis of its differentiation was not performed. In addition, although most skin pathology textbooks classify it as a tumor showing eccrine differentiation, its differentiation remains controversial. @*Objective@#This study investigated clinicopathological features of nodular hidradenoma in Koreans at a tertiary referral center. @*Methods@#We retrospectively investigated 22 patients who presented with nodular hidradenoma at Yeungnam University Hospital between 2000 and 2021. Diagnosis was confirmed by histopathological examination in all the patients. @*Results@#About half of the lesions were located on the head and neck area (45.5%), followed by the trunk (31.8%). Histopathological examination revealed that tumor cells in most of the cases consisted of cuboidal and clear cells; however, in some cases there were several specific modified cells such as clear cells (9.1%), squamoid cells (4.5%), and poroid cells (22.7%). Considering the morphological characteristic of tubular structures, most cases (90.9%) showed apocrine differentiation, and only 2 cases (9.1%) showed eccrine differentiation. @*Conclusion@#Considering the characteristics of cells and tubular structures constituting tumors, it is reasonable to consider nodular hidradenoma as a tumor with apocrine differentiation rather than with eccrine differentiation, which had previously been the predominant classification. Furthermore, there still is no distinct marker for determining whether cells differentiate into eccrine or apocrine tissues and further studies are therefore needed.

ABSTRACT

Lactase non-persistence (LNP), one of the causes of lactose intolerance, is related to lactase gene associated single nucleotide polymorphisms (SNPs). Since the frequency of LNP varies by ethnic group and country, the research to reveal the presence or absence of LNP for specific people has been conducted worldwide. However, in East Asia, the study of lactase gene associated SNPs have not been sufficiently examined so far using ancient human specimens from archaeological sites. In our study of Joseon period human remains (n=14), we successfully revealed genetic information of lactase gene associated SNPs (rs1679771596, rs41525747, rs4988236, rs4988235, rs41380347, rs869051967, rs145946881 and rs182549), further confirming that as for eight SNPs, the pre-modern Korean people had a lactase non-persistent genotype. Our report contributes to the establishment of LNP associated SNP analysis technique that can be useful in forthcoming studies on human bones and mummy samples from East Asian archaeological sites.

ABSTRACT

Background/Aims@#Some sessile serrated lesions (SSLs) progress into dysplasia and colorectal cancer, however, the clinical and endoscopic characteristics of SSLs with dysplasia remain to be determined. In this study, we elucidated these characteristics in SSLs with dysplasia/carcinoma, compared with those of SSLs without dysplasia. @*Methods@#We retrospectively collected the clinical, endoscopic, and pathological data of 254 SSLs from 216 patients endoscopically resected between January 2009 and December 2020. @*Results@#All SSLs included 179 without dysplasia and 75 with dysplasia/carcinoma, including 55 with low-grade dysplasia, 10 with high-grade dysplasia, and 10 with submucosal cancer. In clinical characteristics, SSLs with dysplasia/carcinoma were significantly associated with advanced age, metabolic diseases, and high-risk adenomas. In endoscopic characteristics, SSLs with dysplasia/carcinoma were significantly associated with the distal colon, large size, polypoid morphology, surface-changes, no mucus cap, and narrow-band imaging international colorectal endoscopic classification (NICE) type 2/3. In the multivariate analysis, high-risk adenomas (odds ratio [OR], 2.98; p = 0.01), large size (OR, 1.18; p < 0.01), depression (OR, 11.74; p = 0.03), and NICE type 2/3 (OR, 14.97; p < 0.01) were significantly associated with SSLs with dysplasia/carcinoma. @*Conclusions@#SSLs had a higher risk of dysplasia in the distal colon than in the proximal colon. SSLs with large size, depression, and adenomatous surface-patterns, as well as those in patients with high-risk adenomas, increased the risk of dysplasia/ carcinoma. This suggests that the clinical and endoscopic characteristics can aid in the diagnosis and management of SSLs with dysplasia/carcinoma.

ABSTRACT

Spindle cell lipoma is a rare benign neoplasm that features a mixture of evenly aligned spindle cells, mature adipocytes, and ropey collagen. Most cases of spindle cell lipoma are found in the subcutaneous tissue, and intradermal spindle cell lipoma is rarely reported. We present a case of intradermal spindle cell lipoma in a 46-year-old female who presented with a 0.7-cm flesh-colored and dome-shaped nodule on the right temple that had developed 6 years ago. This mass was excised, and upon histopathologic examination, an unencapsulated lesion was located in the dermis, which consisted of bland spindle cells, scanty mature adipocytes, rare lipoblasts, and ropey collagen bundles with prominent basophilic myxoid stroma. Immunohistochemical staining showed diffuse positivity for CD34, negativity for the S-100 protein, and loss of retinoblastoma protein expression. Based on these features, intradermal low-fat spindle cell lipoma was diagnosed. No evidence of local recurrence was observed 4 months after excision. Intradermal low-fat spindle cell lipomas are extremely rare and can easily be mistaken for tumors that have similar clinical and histopathological findings. Herein, we report a globally rare case of an intradermal low-fat spindle cell lipoma.

ABSTRACT

Superficial CD34-positive fibroblastic tumor (SCPFT) is a recently described disease entity characterized by marked nuclear pleomorphism, low mitotic count, and diffuse CD34 positivity. It is a rare, distinctive, low-grade fibroblastic neoplasm. To date, only 44 cases have been reported in the English-language literature. Herein, we report two cases of SCPFT involving a 48-year-old male and a 22-year-old male with superficial tumors on the right and left thighs, respectively. Excision was performed in both cases. Histologically, both tumors showed spindle-to-epithelioid cells arranged in fascicular or sheet-like patterns. Most cells displayed granular or eosinophilic glassy cytoplasm, marked nuclear pleomorphism, and a low mitotic rate. On immunohistochemical staining, tumor cells were diffusely positive for CD34 and negative for S100 protein, smooth muscle actin, and desmin. After wide excision, neither patient experienced recurrence or metastasis after 16 months and 11 months of clinical follow-up, respectively. To the best of our knowledge, these are the first two cases of SCPFT reported in Korea. We believe these case reports would contribute to the clinicopathological understanding of SCPFT and assist clinicians in differentiating this tumor from other superficial soft tissue neoplasms.

ABSTRACT

In arctic zone of West Siberia, native people’s bodies were sometimes mummified inside the medieval graves. In 2013 to 2017, we conducted the excavations of medieval graves at Zeleny Yar cemetery in Yamalo-Nenets Autonomous Okrug.Among the burials, current report deals with the mummy grave #79. During the investigation, bronze plate and strips, woven or fur clothing, leather strap, beads, bronze bracelets, and iron knife etc. were collected. Anatomical and radiological research showed that the mummy was found intact with hair, skin, and skeletons, but the preservation status of soft tissue differed greatly depending on the area. The brain and eyes were well preserved, but the chest and abdominal organs almost disappeared. The arms were preserved to some extent, but only the bones remained in the legs. The West Siberian mummy could be a great resource for anthropologists to reveal the biological aspects of arctic indigenous people.

ABSTRACT

Piloleiomyoma originates from the arrector pili muscles. Multiple piloleiomyoma lesions may occur, especially on the trunk and extremities. However, multiple lesions throughout the body are rare. We present a case of generalized cutaneous piloleiomyomatosis in a 72-year-old man who had numerous lesions throughout his body. Clinically, the patient presented with fixed and non-tender reddish to brownish papules and nodules mainly on the back and extensors of extremities. Punch biopsy was performed, and the specimen was stained with hematoxylin and eosin, revealing interweaving fascicles of cigar-like spindle cells on the upper dermis. On immunohistochemical staining, tumor cells were positive for smooth muscle actin. Based on these features, we diagnosed the patient with generalized cutaneous piloleiomyomatosis.

ABSTRACT

Purpose@#Recent studies have revealed that the expression of cancer-associated fibroblast (CAF) activation biomarkers in cancer cells is associated with clinical outcomes in patients with certain types of malignant tumors. However, whether the expression of CAF activation biomarkers affects the prognosis of colorectal cancer (CRC) has not been fully elucidated. This study aimed to evaluate the association between the expression of CAF activation biomarkers in cancer cells with cancer invasion and long-term oncological outcomes in patients with CRC. @*Methods@#Cancer specimens obtained from 135 patients with stage I–III CRC were examined using immunohistochemical staining to evaluate the expression of fibroblast specific protein-1 (FSP-1), fibroblast activation protein α (FAPα), α-smooth muscle actin (α-SMA), and vimentin in cancer cells. @*Results@#FSP-1 expression in cancer cells was significantly associated with lymphatic invasion, perineural invasion, tumor (T) status, and lymph node (N) status. FAPα expression in cancer cells was significantly associated with lymphatic invasion. On univariate and multivariate analyses, FSP-1 and α-SMA expression in cancer cells were associated with a short 10-year overall survival (OS) and high 10-year systemic recurrence (SR), respectively. Tumor budding was associated with a short 10-year OS. However, FAPα and vimentin did not contribute to the prognosis in this study. @*Conclusion@#In this study, we found that FSP-1 expression in cancer cells was related to cancer invasion. Additionally, FSP-1 and α-SMA expression in cancer cells was associated with 10-year OS and SR, respectively. Therefore, these markers may be used as predictors of long-term oncological outcomes in patients with CRC.

ABSTRACT

A three-dimensional (3D) segmentation and model reconstruction is a specialized tool to reveal spatial interrelationship between multiple internal organs by generating images without overlapping structures. This technique can also be applicable to mummy studies, but related reports have so far been very rare. In this study, we applied 3D segmentation and model reconstruction to computed tomography images of a Korean mummy with congenital diaphragmatic hernia. As originally revealed by the autopsy in 2013, the current 3D reconstruction reveals that the mummy’s heart is shifted to the left due to the liver pushing up to thoracic cavity thorough diaphragmatic hernial defect. We can generate 3D images by calling up the data exclusively from mummy’s target organs, thus minimizing the confusion of diagnosis that could be caused by overlapping organs.

ABSTRACT

As a technique mainly hiring in forensic investigation field to identify the descents, craniofacial reconstruction (CFR) is also used in archaeology to create the faces from ancient or medieval human remains, when there is little information about his/her appearance. Eung-Cheok Ko (1531–1605) was a writer and scholar in the mid Joseon period. In January of 2019, His mummified body was found at Gumi, Kyeonsangbuk-do, Korea. The remains were anthropologically examined, and archaeological CFR was also requested for this case. This report reveals the case’s facial reconstruction process and his portrait that is drawn based on the 3-dimensional CFR result.

ABSTRACT

Background@#Mac-2 binding protein glycosylation isomer (M2BPGi) was introduced as a noninvasively measurable serologic marker for liver fibrosis. Acoustic radiation force impulse imaging (ARFI) elastography is another noninvasive method of measuring hepatic fibrosis. There are limited data about the correlations between histologic fibrosis grade and noninvasively measured markers, including M2BPGi and ARFI. @*Methods@#This prospective study was conducted among patients admitted consecutively for liver resection, cholecystectomy, or liver biopsy. ARFI elastography, serum M2BPGi levels, and the AST to Platelet Ratio Index (APRI) score were evaluated before histologic evaluation. Histologic interpretation was performed by a single pathologist using the METAVIR scoring system. @*Results@#In patients with high METAVIR scores, M2BPGi levels and ARFI values showed statistically significant differences between patients with fibrosis and those without fibrosis. In 41 patients with hepatocellular carcinoma, as METAVIR scores increased, M2BPGi levels also tended to increase (p=0.161). ARFI values changed significantly as METAVIR scores increased (p=0.039). In 33 patients without hepatocellular carcinoma, as METAVIR scores increased, M2BPGi levels significantly increased (p=0.040). ARFI values also changed significantly as METAVIR scores increased (p=0.033). M2BPGi levels were significantly correlated with ARFI values (r=0.604, p<0.001), and APRI values (r=0.704, p<0.001), respectively. @*Conclusions@#Serum M2BPGi levels increased with liver fibrosis severity and could be a good marker for diagnosing advanced hepatic fibrosis regardless of the cause of liver disease.

ABSTRACT

Alcohol-related liver disease (ALD) has become the major cause of liver transplantation (LT) in Korea, and is currently the most common cause of LT in Europe and the United States. Although, ALD is one of the most common indications for LT, it is traditionally not considered as an option for patients with ALD due to organ shortages and concerns about relapse. To select patients with terminal liver disease due to ALD for transplants, most LT centers in the United States and European countries require a 6-month sober period before transplantation. However, Korea has a different social and cultural background than Western countries, and most organ transplants are made from living donors, who account for approximately twice as many procedures as deceased donors. Most LT centers in Korea do not require a specific period of sobriety before transplantation in patients with ALD. As per the literature, 8%–20% of patients resume alcohol consumption 1 year after LT, and this proportion increases to 30%–40% at 5 years post-LT, among which 10%–15% of patients resume heavy drinking. According to previous studies, the risk factors for alcohol relapse after LT are as follows: young age, poor familial and social support, family history of alcohol use disorder, previous history of alcohol-related treatment, shorter abstinence before LT, smoking, psychiatric disorders, irregular follow-up, and unemployment. Recognition of the risk factors, early detection of alcohol consumption after LT, and regular follow-up by a multidisciplinary team are important for improving the short- and long-term outcomes of LT patients with ALD.

ABSTRACT

Background@#To evaluate workload in emergency rooms (ERs) among clinical specialties including neurology and investigate characteristics of neurological consultations in ER. @*Methods@#A nationwide survey was conducted to evaluate the number of specialists, resident physicians/surgeons, and emergency consultations of each clinical specialty in Korean tertiary referral hospitals from 2018 to 2019. Characteristics of neurological emergency consultations during the same period were investigated in one of the hospitals that participated. @*Results@#A total of 23 hospitals were included. Four irrelevant clinical specialties were excluded. The number of neurology specialists and resident physicians were 12.5/hospital (4.1% of all specialists) and 6.4/hospital (3.4% of all resident physicians/surgeons), respectively, while the mean numbers of specialists and resident physicians or surgeons per clinical specialty were 13.7/hospital and 8.6/hospital, respectively. Neurological consultations accounted for 11.0% of all ER consultations for severe patients (Korean Triage and Acuity Scale level 1-3). Annual ER consultations for severe patients per neurology specialist was 274.1, which was only second to pediatrics (290.0). Annual ER consultations for severe patients per resident physician was 406.6 which was 1.6 times higher than the second highest (internal medicine, 247.0). Frequent conditions for neurological ER consultation were dizziness (24.8%), motor weakness (23.9%), headache (10.6%), dysarthria (9.9%), and seizures (7.7%). Frequent primary diagnoses were cerebrovascular diseases (29.0%) and episodic and paroxysmal disorders (24.9%). @*Conclusions@#Workloads of neurology specialists for ER consultation were significantly heavy, and the workload of neurology resident physicians was the heaviest among all specialties. This should be considered in health care policies.

ABSTRACT

Background@#The military was one of the first groups in Korea to complete mass vaccination against the coronavirus disease 2019 (COVID-19) due to their high vulnerability to COVID-19.To confirm the effect of mass vaccination, this study analyzed the patterns of confirmed cases within Korean military units. @*Methods@#From August 1 to September 15, 2021, all epidemiological data regarding confirmed COVID-19 cases in military units were reviewed. The number of confirmed cases in the units that were believed to have achieved herd immunity (i.e., ≥ 70% vaccination) was compared with the number of cases in the units that were not believed to have reached herd immunity (< 70% vaccination). Additionally, trends in the incidence rates of COVID-19 in the military and the entire Korean population were compared. @*Results@#By August 2021, 85.60% of military personnel were fully vaccinated. During the study period, a total of 174 COVID-19 cases were confirmed in the 39 units. More local transmission (herd immunity group vs. non-herd immunity group [%], 1 [0.91] vs. 39 [60.94]) and hospitalizations (12 [11.01] vs. 13 [27.08]) occurred in the units that were not believed to have achieved herd immunity. The percentage of fully vaccinated individuals among the confirmed COVID-19 cases increased over time, possibly due to the prevalence of the delta variant. Nevertheless, the incidence rate remained lower in military units than in the general Korean population. @*Conclusion@#After completing mass vaccination, the incidence rates of COVID-19 infection in the military were lower than those in the national population. New cluster infections did not occur in vaccinated units, thereby suggesting that herd immunity has been achieved in these military units. Further research is needed to determine the extent to which levels of nonpharmacological intervention can be reduced in the future.

ABSTRACT

Background@#and Purpose We aimed to develop a model predicting early recanalization after intravenous tissue plasminogen activator (t-PA) treatment in large-vessel occlusion. @*Methods@#Using data from two different multicenter prospective cohorts, we determined the factors associated with early recanalization immediately after t-PA in stroke patients with large-vessel occlusion, and developed and validated a prediction model for early recanalization. Clot volume was semiautomatically measured on thin-section computed tomography using software, and the degree of collaterals was determined using the Tan score. Follow-up angiographic studies were performed immediately after t-PA treatment to assess early recanalization. @*Results@#Early recanalization, assessed 61.0±44.7 minutes after t-PA bolus, was achieved in 15.5% (15/97) in the derivation cohort and in 10.5% (8/76) in the validation cohort. Clot volume (odds ratio [OR], 0.979; 95% confidence interval [CI], 0.961 to 0.997; P=0.020) and good collaterals (OR, 6.129; 95% CI, 1.592 to 23.594; P=0.008) were significant factors associated with early recanalization. The area under the curve (AUC) of the model including clot volume was 0.819 (95% CI, 0.720 to 0.917) and 0.842 (95% CI, 0.746 to 0.938) in the derivation and validation cohorts, respectively. The AUC improved when good collaterals were added (derivation cohort: AUC, 0.876; 95% CI, 0.802 to 0.950; P=0.164; validation cohort: AUC, 0.949; 95% CI, 0.886 to 1.000; P=0.036). The integrated discrimination improvement also showed significantly improved prediction (0.097; 95% CI, 0.009 to 0.185; P=0.032). @*Conclusions@#The model using clot volume and collaterals predicted early recanalization after intravenous t-PA and had a high performance. This model may aid in determining the recanalization treatment strategy in stroke patients with large-vessel occlusion.

ABSTRACT

Systemic lupus erythematosus (SLE) may occur in any organ. In patients with SLE, myocarditis is extremely rare and potentially life-threatening. Herein, we report on a patient with lupus myocarditis, diagnosed by myocardial biopsy, immunologic tests, and clinical manifestations. Our findings suggest that securing time for diagnosis via extracorporeal membrane oxygenation and other intensive care is helpful for obtaining a good prognosis.

ABSTRACT

Molecular biomarker testing is the standard of care for non–small cell lung cancer (NSCLC) patients. In 2017, the Korean Cardiopulmonary Pathology Study Group and the Korean Molecular Pathology Study Group co-published a molecular testing guideline which contained almost all known genetic changes that aid in treatment decisions or predict prognosis in patients with NSCLC. Since then there have been significant changes in targeted therapies as well as molecular testing including newly approved targeted drugs and liquid biopsy. In order to reflect these changes, the Korean Cardiopulmonary Pathology Study Group developed a consensus statement on molecular biomarker testing. This consensus statement was crafted to provide guidance on what genes should be tested, as well as methodology, samples, patient selection, reporting and quality control.
