Lipogranuloma is a chronic inflammatory response to lipid material within tissues and may develop secondary to fat necrosis, trauma, or exogenous lipid exposure. We report a case of postoperative mid-sternal lipogranuloma with milky discharge in a 35-year-old man that occurred 6 months after surgery for gynecomastia performed through a periareolar incision with adjunctive liposuction. The patient presented with two firm, non-tender nodules at the sternal midline, distant from the operative site, and laboratory findings were unremarkable. Surgical exploration revealed milky white discharge, and histopathologic examination demonstrated lipid-laden macrophages, multinucleated giant cells, and fibrosis, consistent with lipogranulomatous inflammation. No evidence of malignancy or infection was identified, and no recurrence was observed during 2 years of follow-up. The proposed mechanisms include displacement of residual ductal epithelium or lipid material during surgical manipulation, as well as postoperative fat necrosis leading to secondary lipogranulomatous inflammation. This case highlights that postoperative lipogranulomatous inflammation may present at sites distant from the primary operative field. Recognition of this entity is important in the evaluation of postoperative chest wall masses to avoid misdiagnosis and unnecessary intervention.

Epidermoid and dermoid cysts are common congenital lesions of the pediatric periorbital region arising from ectodermal inclusion during embryologic development. Although these lesions originate in the soft tissue, chronic pressure from long-standing masses may induce cortical depression or remodeling of adjacent craniofacial bones, particularly in young children with malleable skeletal structures. We report a case of a 26-month-old girl presenting with a small periorbital epidermoid cyst associated with pressure-induced depression of the zygomatic surface. Radiologic evaluation revealed a well-circumscribed cystic lesion abutting the frontal process of the zygoma with smooth cortical indentation and no features suggestive of aggressive osseous pathology. Complete excision was performed through a lateral brow approach with preservation of the periosteum. Histopathologic examination confirmed an epidermoid cyst. Postoperative follow-up demonstrated progressive spontaneous restoration of the zygomatic contour without the need for bone grafting or alloplastic materials, reflecting the osteogenic potential of the pediatric periosteum. This case emphasizes the importance of distinguishing secondary pressure-related bone remodeling from true intraosseous lesions in the pediatric craniofacial region and highlights the capacity for natural osseous recovery following removal of the compressive source. A brief review of relevant embryologic and radiologic considerations is also provided.

Irritable bowel syndrome (IBS) is a chronic, disabling, and functional bowel disorder that significantly affects social functioning and reduces quality of life and increases social costs. The Korean Society of Neurogastroenterology and Motility published clinical practice guidelines on the management of IBS based on a systematic review of the literature in 2017, and planned to revise these guidelines in light of new evidence on the pathophysiology, diagnosis, and management of IBS. The current revised version of the guidelines is consistent with the previous version and targets adults diagnosed with or suspected of having IBS. These guidelines were developed using a combination of de novo and adaptation methods, with analyses of existing guidelines and discussions within the committee, leading to the identification of key clinical questions. Finally, the guidelines consisted of 22 recommendations, including 3 concerning the definition and risk factors of IBS, 4 regarding diagnostic modalities and strategies, 2 regarding general management, and 13 regarding medical treatment. For each statement, the advantages, disadvantages, and precautions were thoroughly detailed. The modified Delphi method was used to achieve expert consensus to adopt the core recommendations of the guidelines. These guidelines serve as a reference for clinicians (including primary care physicians, general healthcare providers, medical students, residents, and other healthcare professionals) and patients, helping them to make informed decisions regarding IBS management.

Objective: Since its development in 2002 by the Korean College of Neuropsychopharmacology and the Korean Society for Affective Disorders, the Korean Medication Algorithm Project for Depressive Disorder (KMAP-DD) has undergone five revisions. Methods: To improve survey efficiency, reflect general clinical practice, and facilitate comparisons with previous KMAP-DD revisions, the overall structure of the questionnaire was retained. The six sections of the questionnaire were as follows:1) pharmacological treatment strategies for major depressive disorder with and without psychotic features; 2) pharmacological treatment strategies for persistent depressive disorder and other depressive disorder subtypes; 3) consensus on treatment-resistant depression; 4) selection of an antidepressant in consideration of safety, adverse effects, and comorbid physical conditions; 5) treatment strategies for special populations (children/adolescents, elderly, and women); and 6) non-pharmacological biological therapies. First-, second-, and third-line treatment recommendations were statistically derived. Results: Compared to KMAP-DD 2021, only minor changes were noted, due to the limited introduction of new medications or treatment modalities. Nonetheless, notable shifts included an increased preference for atypical antipsychotics (AAPs), and higher preference of combination strategies involving AAPs and mood stabilizers, indicating a more proactive and intensive treatment trend in Korea. Conclusion KMAP-DD is expected to serve as a valuable clinical resource by providing expert consensus-based recommendations on specific treatment strategies and pharmacological options for major depressive disorders, thereby supporting the integration of real-world clinical practice with evidence-based medicine.

After the coronavirus disease 2019 pandemic, the widespread adoption of working from home, or teleworking, has prompted extensive research regarding its effects on work productivity and the physical and mental health of employees. In this context, our study aimed to investigate the association between working from home and health-related productivity loss (HRPL).

Poly-D,L-lactic acid (PDLLA) is widely used in facial rejuvenation as a collagen stimulator, with a lower risk of granuloma formation compared to poly-L-lactic acid (PLLA). However, granulomas may still occur. In this case, a 58-year-old woman developed firm, non-tender, bilateral infraorbital granulomas 2 months after her third PDLLA injection for infraorbital hollowing. The lesions were unresponsive to intralesional trichloroacetic acid (TCA) and intense pulsed light therapy, necessitating surgical removal. Histopathological analysis confirmed foreign-body granulomas caused by the PDLLA filler. This case highlights the need for caution when injecting PDLLA into thin-skinned areas like the infraorbital region, where granulomas can be more visible due to limited tissue volume. Although PDLLA fillers are generally safe, granuloma formation remains a potential complication. Early diagnosis and treatment with non-surgical methods, such as intralesional TCA, should be prioritized. If these methods fail, surgical excision, aimed at preserving as much normal tissue as possible, may be necessary for optimal outcomes.

This paper presents a novel approach to the correction of zygomatic malposition and secondary reconstruction orbital floor fractures, highlighting the use of hydrated acellular dermal matrix (ADM), specifically CGDerm One-Step, in a case where traditional solid implants failed to maintain structural integrity and volume. A 27-year-old woman with persistent facial deformities following a traumatic incident underwent a transformative procedure that utilized ADM for volume correction and structural support, addressing significant challenges such as enophthalmos and facial contour depression. This approach was necessitated by the descent of the entire orbital floor and a previously placed implant (Medpor), leading to unsatisfactory volume correction. By integrating ADM with titanium-reinforced fan plates (Synpor), the surgery successfully restored the patient’s facial symmetry and addressed her functional concerns, including diplopia and limited eye movement. Postoperative evaluations demonstrated the long-term effectiveness of this method, with significant improvements in facial contour and eye symmetry. Our findings suggest that ADM, particularly in its hydrated form, offers a reliable alternative to traditional bone grafts and implants for correcting complex craniofacial deformities, providing both aesthetic and functional benefits. This case underscores the importance of adaptable, tissue-mimicking materials in facial reconstructive surgery, offering insights into their potential for broader application in post-traumatic facial corrections.
