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.

Background/Aims: Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly-used medications, and ailments such as arthritis or heart disease, require long-term use of these drugs, which can induce gastroenteropathy with bleeding and ulcers. This study investigated the associations between efficacy, safety, and gastrointestinal symptoms linked to rebamipide and proton pump inhibitor administration in patients requiring long-term NSAID use. Methods: This study was a multi-center, randomized, open-labeled, pilot design. Results: Thirty-three patients were included. Of these, 15 were included in the study group and 18 were in the control group. NSAID-induced gastric ulcers, which were the primary outcome of this study, did not occur in either the study or control group. Changes in the number of small bowel erosions and ulcers were –0.6 ± 3.06 in the study group and 1.33 ± 4.71 in the control group. The number of subjects with mucosal breaks (defined as multiple erosions and/or ulcers) was three (20%) in the study group and six (40%) in the control group (p = 0.427). No serious adverse events occurred in either group. However, dyspepsia and skin rashes occurred in six patients (31.58%) in the study group and 13 (65%) in the control group (p = 0.036). Conclusions Although statistically significant differences were not generated, possibly as a result of the small sample size, mucosal breaks observed via capsule endoscopy revealed that rebamipide was likely to be more effective than lansoprazole in preventing small intestine damage caused by NSAIDs. Furthermore, fewer side-effects emerged with rebamipide.

This report provides a detailed description of the methodology for ophthalmic examinations according to the Korea National Health and Nutrition Examination Survey (KNHANES) VII and VIII (from 2017 to 2021). The KNHANES is a nationwide survey which has been performed since 1998 in representatives of whole Korean population. During the KNHANES VII and VIII, in addition to the ophthalmic questionnaire, intraocular pressure measurement, visual field test, auto refractometry, axial length and optical coherence tomography measurements were included. This new survey will provide not only provide normative and pathologic ophthalmic data including intraocular pressure, refractive error, axial length, visual field and precise measurement of anterior segment, macula and optic nerve with optical coherence tomography, but also a more accurate diagnosis for major adult blindness diseases, including age-related macular degeneration, diabetic retinopathy, glaucoma, and other ocular diseases, for the national Korean population.

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.

OBJECTIVE: The purpose of this study was to test the hypothesis that an increase in the neutrophil-to-lymphocyte ratio (NLR) increases the risk of in-hospital density in patients aged 65 and older, who are hospitalized in intensive care through the emergency rooms. METHODS: A retrospective medical record study was conducted on elderly patients who were admitted to intensive care units via the emergency room. The exclusion criteria were data loss, intensive care unit reentry, cerebrovascular accidents, hematologic disease, and trauma cases. RESULTS: The study included 526 patients; the mean age was 79, and 261 (49.6%) were male. The in-hospital mortality was 18.4% (97 patients). The initial NLR was higher in the non-survivor group than the survivor group, but the difference was not statistically significant (9.82±11.02 vs. 11.48±6.11, P=0.080). In multivariate logistic analysis, the initial NLR had no statistical significance, and the odd ratio was increased from one day later. Comparing the receiver operating characteristic curve of the NLR and Acute Physiology and Chronic Health Evaluation II (APACHE II) and Simplified Acute Physiology Score II (SAPS II) scores, the NLR showed an increase in the area of under curve (AUC) value over time as well as the highest AUC with the SAPS II scores. CONCLUSION In elderly adults, early NLR was found to have weak power to predict in-hospital mortality. Over time, the NLR values more than two days after intensive care unit admission may be useful in predicting the in-hospital mortality for older patients. This may be due to the delay in the immune response and the complex medical history.
