Portal vein gas and pneumatosis cystoides intestinalis are uncommon conditions and have been associated with poor prognosis. They are most commonly caused by necrotizing enterocolitis but may have other causes, and they can be associated with necrotizing and ischemic colitis, intra-abdominal abscess, small bowel obstruction, diverticulitis, colon cancer, and acute pancreatitis. With the more frequent use of computed tomography (CT) scans, portal vein gas and pneumatosis cystoides intestinalis have been increasingly detected in recent years. Because of its high mortality rate, necrotizing enteritis with portal vein gas and pneumatosis cystoides intestinalis may be treated with emergent exploratory laparotomy. We report a case of necrotizing enteritis with portal vein gas and pneumatosis cystoides intestinalis in a 47-year-old man treated with intensive medical management and delayed operation due to unstable condition and surgical mortality. He had good clinical results without complications after the delayed operation.

Although chronic myelogenous leukemia (CML) may be involved in any part of the body, infiltration of the body fluid has rarely reported in the literature. Here we report on a 35 year-old male patient who was diagnosed chronic myelogenous leukemia ten years previously and he received allogenic hematopoietic stem cell transplantation. He then presented with left knee pain eight years after the initial diagnosis. MRI revealed a soft tissue mass at the distal femur. Cytology of the joint fluid revealed myeloblasts, promyelocytes, eosinophilic myelocytes, band neutrophils, megakaryocytes and orthochromatic erythroblasts, which was all consistent with leukemic infiltration of the knee joint fluid. The immunohistochemistry was positive for CD34, CD117 and myeloperoxidase (MPO). Despite that the patient underwent radiation therapy, MRI revealed growth of the mass, and ten months later, the lymphoid blast phase of CML was confirmed after biopsy. The patient received an above knee amputation. Five months later, multiple masses were revealed on PET-CT at the left iliopsoas muscle, abdominal wall and bones. Bilateral pleural effusion occurred shortly after this. Cytologic evaluation of the pleural fluid also revealed blast-like cells, and histologic evaluation of the abdominal mass confirmed the lymphoid blast phase of CML with positivity for CD3, UCHL-1, CD34 and CD117, but negativity for MPO.

BACKGROUND: This study evaluated the accuracy of fine needle aspiration cytology (FNAC) in cases of follicular neoplasm (FN) on the basis of histologic diagnosis, and reviewed the cytologic findings of FN according to the FNAC. METHODS: Among the 66 cases diagnosed with thyroid FN by FNAC during the 7-year period from 2003 to 2009, 36 cases that had undergone thyroid surgery were available for review. Cytologic diagnosis was compared with the histologic diagnosis of each case. RESULTS: Among the 36 cases with a cytologic diagnosis of thyroid FN, histologic diagnosis was as follows: 20 follicular adenomas (55.6%), 3 Hurthle cell adenomas (8.3%), 2 follicular carcinomas (5.6%), 8 nodular goiters (22.2%), 2 papillary carcinomas (5.6%), and 1 Hashimoto's thyroiditis (2.8%), resulting in a diagnostic accuracy of FNAC for thyroid FN of 69.5%. CONCLUSIONS: This study shows that FNAC for thyroid FN is a useful primary screening method because when FN is diagnosed by FNAC, the rate of FN histologic diagnosis is relatively high, however, adequate sampling and experience is a prerequisite for this procedure.

PURPOSE:
Gastrointestinal stromal tumors (GISTs) frequently harbor activating gene mutations in either KIT or platelet-derived growth factor receptor A (PDGFRA) and are highly responsive to several selective tyrosine kinase inhibitors. In this study, a targeted next-generation sequencing (NGS) assay with an Oncomine Focus Assay (OFA) panel was used for the genetic characterization of molecular targets in 30 Korean patients with GIST.
MATERIALS AND METHODS:
Using the OFA that enables rapid and simultaneous detection of hotspots, single nucleotide variants (SNVs), insertion and deletions (Indels), copy number variants (CNVs), and gene fusions across 52 genes relevant to solid tumors, targeted NGS was performed using genomic DNA extracted from formalin-fixed and paraffin-embedded samples of 30 GISTs.
RESULTS:
Forty-three hotspot/other likely pathogenic variants (33 SNVs, 8 Indels, and 2 amplifications) in 16 genes were identified in 26 of the 30 GISTs. KIT variants were most frequent (44%, 19/43), followed by 6 variants in PIK3CA, 3 in PDGFRA, 2 each in JAK1 and EGFR, and 1 each in AKT1, ALK, CCND1, CTNNB1, FGFR3, FGFR4, GNA11, GNAQ, JAK3, MET, and SMO. Based on the mutation types, majority of the variants carried missense mutations (60%, 26/43), followed by 8 frameshifts, 6 nonsense, 1 stop-loss, and 2 amplifications.
CONCLUSIONS
Our study confirmed the advantage of using targeted NGS with a cancer gene panel to efficiently identify mutations associated with GISTs. These findings may provide a molecular genetic basis for developing new drugs targeting these gene mutations for GIST therapy.

Frailty is a condition marked by a progressive decline in physiological functioning due to aging, leading to increased disease morbidity and rising healthcare costs. Therefore, it is important to prevent frailty through proper management. Not only does a lack of physical activity contribute to frailty, but inadequate dietary intake, resulting from decreased appetite and malabsorption, is also a significant risk factor. This study aimed to develop a 16-week algorithm to assess the nutritional risks associated with frailty, provide personalized nutritional solutions, and manage frailty risk factors through continuous monitoring and periodic reassessment. A total of 20 indicators were selected to create a nutritional health score. The selected indicators encompassed nutritional risk factors for frailty, disease history, and hematological factors. Reassessments were designed to occur at four-week intervals to revise personalized management goals and adjust solutions. Metrics were prioritized to provide a personalized solution. A user-friendly monitoring system was developed that leveraged voice recognition technology to determine compliance. It is anticipated that the algorithm will serve several purposes. First, this outcome will allow us to help prevent and delay the onset of frailty by utilizing a mobile app. Second, it will reduce the time and economic costs associated with nutritional management. Finally, it will facilitate future professional counseling and monitoring.

Background:
The Pandemic Grief Risk Factors (PGRFs) was developed as a self-report tool to compile a comprehensive list of unique risk factors related to grief when experiencing a coronavirus disease 2019 (COVID-19) loss. We explored the reliability and validity of the PGRF among healthcare workers who witnessed their patients’ deaths during the COVID-19 pandemic. Further, we examined whether the general severity of PGRF may have been associated with work-related stress and pandemic grief reactions.
Methods:
An online survey was conducted among tertiary hospital healthcare workers (doctors and nursing professionals) who had witnessed the deaths of patients they cared for.Pandemic Grief Scale for healthcare workers, the Stress and Anxiety to Viral Epidemics-3 items, the Patient Health Questionnaire-9, and the Generalized Anxiety Disorder-7 responses were collected.
Results:
In total, 267 responses were analyzed. The single-factor structure of the Korean version of the PGRF showed a good fit for the model. The scale demonstrated good internal consistency and convergent validity with other depression and anxiety rating scales. The mediation analysis revealed that work-related stress directly influenced pandemic grief reactions positively, and depression, anxiety, and general severity of grief risk factors partially mediated the association positively.
Conclusion
Among healthcare workers who witnessed the deaths of their patients due to COVID-19, the Korean version of the PGRF was valid and reliable for measuring the overall severity of PGRF. The PGRF can be used to identify individuals at risk for dysfunctional grief.

BACKGROUND: Aberration of the cell cycle regulatory proteins has been reported to contribute to the development and progression of human malignancy. We studied the expression of G1/S cell cycle regulatory proteins to investigate the carcinogenesis in cutaneous squamous cell lesions. METHODS: We evaluated the expressions of p16, pRb, cyclin D1 and Ki-67 protein by immunonohistochemistry in cases of normal skin (n=15), seborrheic keratosis (SK; n=26), actinic keratosis (AK; n=30), Bowen's disease (BD; n=37), keratoacanthoma (KA; n=23), and squamous cell carcinoma (SCC; n=22). RESULTS: The Ki-67 expression gradually increased from SK, through AK, to BD. The expression of p16 was more increased in BD than that in AK. The decreased expressions of p16 and Rb, and the increased expression of cyclin D1 were observed to a greater degree in SCC than those in BD. The expressions of cyclin D1 and Ki-67 were higher in SCC than those in KA. CONCLUSIONS: The altered expressions of p16, Rb, and cyclin D1 were considered to be related to the carcinogenesis in the cutaneous squamous cell lesions. Therefore, immunohistochemical studies of the cell cycle regulatory proteins and a combined analysis may be helpful as an adjunct to the histomorphology in the diagnosis of cutaneous squamous cell lesions.

Benign metastatic leiomyomatosis (BML) is a rare disease characterized by smooth muscle cell proliferation in extrauterine sites including the lung, abdomen, pelvis, and retroperitoneum. Depending on location, BML is classified as intravenous leiomyomatosis and diffuse peritoneal leiomyomatosis. Pathogenesis of BML can be iatrogenic after previous myomectomy or hysterectomy, hormonal, or coelomic metaplasia. Treatment options are observation, hormonal suppression, and/or surgical debulking via laparotomy or laparoscopy. Laparoscopic surgery is gaining in popularity in the gynecologic field compared to laparotomic surgery and single-port laparoscopy has the benefits of cosmesis and early tissue extraction by transumbilical morcellation. We report a 39-year-old woman with BML who underwent single-port laparoscopy debulking surgery.
