Doxazosin is an adrenergic alpha-1 receptor antagonist used to treat lower urinary tract symptoms that are common in prostatic hyperplasia. To our knowledge, few cases of gynecomastia and mastodynia, as a complication of adrenergic alpha-1 receptor antagonist, have been reported to date; no cases have been reported in Korea. We describe a case involving a 78-year-old man treated for prostatic hyperplasia with 13 months of doxazosin. He complained about unilateral gynecomstia and mastodynia. Five months after the discontinuation of doxazosin, the gynecomastia was significantly improved. This is the first reported case of gynecomastia and mastodynia associated with doxazosin use in Korea.

Cardiovascular malformations, such as bicuspid aortic valve and coarctation of the aorta, are more prevalent in patients with Turner syndrome than in the general population. Here, we describe the case of a 35-year-old female with Turner syndrome who was admitted to our hospital with a fever caused by infective endocarditis. Aortic coarctation was diagnosed using computed tomography. The patient was treated with antibiotics and a stent was then implanted. Endovascular therapy using stents is a safe and effective treatment option for aortic coarctation in patients with Turner syndrome.

Translocator protein 18 kDa (TSPO) is a mitochondrial protein highly expressed on reactive microglia and astrocytes, and is considered as a biomarker for neurodegeneration and brain damage, especially neuroinflammation. Toll-like receptors (TLRs) are closely related with inflammatory responses of microglia and astrocytes and these signaling pathways regulate neuroinflammation. Previous reports have identified the anti-inflammatory effects of TSPO ligands, however study of their effects in relation to the TLR signaling was limited. Here, we investigated the effects of five representative TSPO ligands on microglia and astrocytes following activation by various TLR ligands. Our results show that TSPO ligands reduce the pro-inflammatory response elicited by the TLR ligands with more profound effects on microglia than astrocytes.

Peri-implantitis, in which inflammation caused by plaque and biofilm on the implant surface spreads to the hard tissue, can be treated by decontamination of the implant surface and reconstruction of the lost hard tissue through surgical methods. We have described the management of 3 peri-implantitis cases by decontamination of the implant surface using a round titanium brush and regenerative therapy. All cases showed clinical improvements, and no further radiographic bone loss was observed during a 2-year follow-up. This treatment method can be effective for clinical improvement and bone regeneration. However, a longer follow-up period is necessary to support these outcomes.

Circadian rhythm is a 24-hour cycle of behavioral and physiological changes. Disrupted sleep-wake patterns and circadian dysfunction are common in patients of Alzheimer Disease (AD) and are closely related with neuroinflammation. However, it is not well known how circadian rhythm of immune cells is altered during the progress of AD. Previously, we found presenilin 2 (Psen2) N141I mutation, one of familial AD (FAD) risk genes, induces hyperimmunity through the epigenetic repression of REV-ERBα expression in microglia and bone marrow-derived macrophage (BMDM) cells. Here, we investigated whether repression of REV-ERBα is associated with dysfunction of immune cell-endogenous or central circadian rhythm by analyses of clock genes expression and cytokine secretion, bioluminescence recording of rhythmic PER2::LUC expression, and monitoring of animal behavioral rhythm. Psen2 N141I mutation down-regulated REV-ERBα and induced selective over-production of IL-6 (a well-known clock-dependent cytokine) following the treatment of toll-like receptor (TLR) ligands in microglia, astrocytes, and BMDM. Psen2 N141I mutation also lowered amplitude of intrinsic daily oscillation in these immune cells representatives of brain and periphery. Of interest, however, the period of daily rhythm remained intact in immune cells. Furthermore, analyses of the central clock and animal behavioral rhythms revealed that central clock remained normal without down-regulation of REV-ERBα. These results suggest that Psen2 N141I mutation induces hyperimmunity mainly through the suppression of REV-ERBα in immune cells, which have lowered amplitude but normal period of rhythmic oscillation. Furthermore, our data reveal that central circadian clock is not affected by Psen2 N141I mutation.

Purpose:
This study aimed to analyze the prognosis of implant placement after maxillary sinus perforation repair using a collagen membrane during sinus elevation surgery.Materials and Methods: The radiographic and clinical data of 27 patients who underwent simultaneous or delayed implant placement with perforation repair (using collagen membranes) were retrospectively analyzed. The patients were divided into the following three groups: group 1: perforation repair, bone grafting, and simultaneous implant placement (nine patients, 19 implants); group 2: perforation repair, no bone grafting, and simultaneous implant placement (11 patients, 19 implants); group 3: perforation repair, bone grafting, and delayed implant placement (seven patients, 15 implants). The follow-up period was at least 2 years for all patients.
Results:
No significant differences in implant survival rates were observed between groups. Marginal bone loss was minimal in all groups with some exceptions. The thickness of the maxillary sinus measured on the day of surgery differed significantly between the groups, potentially attributed to the variations in the surgical materials employed. However, the thickness normalized in all groups at 1-year follow-up.
Conclusion
This study suggests that simultaneous and delayed implant placement in cases of perforated maxillary sinus membranes repaired with collagen membranes during sinus elevation surgery can achieve favorable long-term outcomes. In certain cases, simultaneous implant placement without bone grafting is a viable option.

Purpose:
This study was performed to evaluate the safety and feasibility of skin adhesives and to compare postoperative and cosmetic outcomes after wound closure in single-port laparoscopic appendectomy (SPLA) between skin adhesives and steri-strips.
Methods:
This was a single-center retrospective study. We included 22 and 47 patients in whom skin adhesive and steri-strips were used respectively, for skin closure after subcuticular suturing in SPLA between August 2014 and 2020. The patient scar assessment questionnaire (PSAQ) was completed postoperatively to assess postoperative cosmetic outcomes.
Results:
On the postoperative day, patients in whom skin adhesive was used had significantly lower numeric rating scores than in whom steri-strips were used (2.8 ± 0.8 vs. 3.9 ± 0.8, p < 0.001). The frequency of analgesic administration within 24 hours and between 24 and 48 hours after surgery was significantly lower in the skin adhesive group compared to the wound closure strip group (1.4 ± 0.8 vs. 2.7 ± 1.2, p = 0.013 and 0.2 ± 0.4 vs. 0.7 ± 0.9, p = 0.002, respectively). In the PSAQ, “satisfaction with appearance” and “satisfaction with symptoms” subitem scores were significantly lower in patients in whom skin adhesive was used (11.3 ± 3.0 vs. 15.1 ± 4.5, p = 0.006 and 6.5 ± 1.8 vs. 9.5 ± 3.3, p = 0.003), whereas, “appearance” and “consciousness” subitems revealed no statistically significant differences between the groups.
Conclusion
Liquid skin adhesive closures seem to be safe and feasible and cause less postoperative pain, resulting in greater patient satisfaction with postoperative scars than wound closure strip closure after subcuticular suturing in SPLA.

OBJECTIVE: To evaluate the usefulness of serum concentrations of macrophage migration inhibitory factor (MIF) of patients with ovarian cysts for differential diagnosis of endometrioama. METHOD: From Jan. 2003 to Dec. 2004, preoperative serum MIF levels were assessed in 28 women with endometrioma, 32 with benign epithelial tumor, 23 with functional and simple cysts, 22 with benign mature cystic teratoma, and 25 women without ovarian tumor as control. MIF levels were determined using an ELISA (Quantikine Human MIF immunoassay, R&D Systems, Inc., USA). RESULTS: Mean MIF levels were higher in all groups with benign tumors than control (all p<0.01), but there was no significant difference between benign tumor groups (p=0.95). There was no significant correlation between MIF levels and tumor volume, body mass index (BMI) (p=0.635, 0.674 respectively) Serum MIF level had significant correlation with count of WBC and neutrophils (p=0.008, 0.024 respectively), but had no correlation with count of lymhocytes and monocytes (p=0.688, 0.294 respectively). CONCLUSIONS: This study showed a marked increase in MIF concentrations in the peripheral blood of patients with endometrioma, but there was no significant difference with other benign tumors. Serum MIF level had significant correlation with count of WBC and neutrophils. These suggest serum MIF level has no usefulness for differential diagnosis of endometrioma from other benign ovarian cysts.
