Purpose: To report a case of extensive syphilitic punctate inner retinitis (SPIR) triggering bilateral macular ischemia after intravitreal triamcinolone injections, and the multimodal retinal imaging findings.Case summary: A 69-year-old male patient with nonproliferative diabetic retinopathy was transferred to our hospital because of bilateral visual deterioration (to counting fingers) after the first intravitreal triamcinolone injection. Fundus examination revealed numerous yellow punctate precipitates in the superficial retinae, retinal arteriolitis, and vitritis. The punctate lesions and surrounding retinal regions showed decreased vascular density on optical coherence tomography angiography, and focal hypofluorescence on fluorescein angiography. The patient was positive for all of the Venereal Disease Research Laboratory test, the fluorescent treponemal antibody-absorption test, and Treponema pallidum hemagglutination; we diagnosed bilateral SPIR. After treatment with aqueous crystalline penicillin solutions (24 million units per day for 14 days), the punctate lesions reduced but arteriolitis progressed to obliterative vasculitis. After 6 months, the bilateral SPIR and vitritis resolved, and the bilateral visual acuity improved to 20/100. However, inner retinal and macular ischemia persisted because of capillary nonperfusion attributable to obliterative vasculitis. Conclusions Extensive SPIR can develop after an initial intravitreal steroid injection; the inner retinal ischemia and visual loss may persist after treatment because obliterative vasculitis develops. Therefore, patients scheduled for intravitreal steroid injections should be screened for syphilis infection.

PURPOSE: This study aimed to identify utilization of the work-family support policy (WFSP) and factors affecting retention intention among Korean female military officers. METHODS: This cross-sectional survey recruited 103 married female officers from the Korean Army, Navy, and Air force with preschool-aged children through convenience and snowball sampling. Via online surveys from June to November, 2018, the participants self-reported retention intention, work-family conflict, job satisfaction, and utilization of the WFSP. The data were analyzed using descriptive statistics, independent t-tests, one-way analysis of variance, Pearson's correlation coefficient, and multiple linear regression. RESULTS: Retention intention (22.29±5.98) was reported at the mid-level, lower than scores reported in the literature for female workers. Work-family conflict (32.51±5.29) and job satisfaction (63.10±7.45) were above the midpoint levels. Use of maternity leave (100.0%) and parental leave (92.2%) was high, especially compared to the rates of child-care day off (20.4%) and parenting time (20.4%). ‘Noticeable increases in childcare services within the army’ (22.8%) was reported as the supportive measure needed the most by female military officers. Job satisfaction (β=.43, p≤.001), the use of parenting time (β=−0.29, p=.002), living type (β=−.18, p=.043), and service type (β=−.16, p=.035) significantly influenced retention intention. CONCLUSIONS: The findings highlight the priority areas of importance within the WFSP and suggest that a family-friendly culture can improve female officers' retention intention. Accordingly, policy changes at the Ministry of National Defense improving the system to enhance a family-friendly culture in the military is expected to strengthen the retention intention of female officers and contribute to excellence in the military workforce.

Simultaneous occurrence of remote intracerebral hemorrhage (ICH) and intracranial aneurysmal subarachnoid hemorrhage is very rare. We report on a case of concurrent hypertensive ICH at the left thalamus and rupture of an intracranial aneurysm at the bifurcation of the single A2 segment of the anterior cerebral artery in a 64-year-old woman, which was clipped previously, with review of the literature. To our knowledge, this is the first case report demonstrating bleeding of previously clipped aneurysm with simultaneous hypertensive ICH. Hypertensive crisis following ICH seems to have provoked rupture of the residual aneurysm.

BACKGROUND: Oxytocin (OXT) has been reported to act as a growth regulator in various tumor cells. However, there is a paucity of data on the influence of OXT on cell proliferation of corticotroph adenomas. This study aimed to examine whether OXT affects cell growth in pituitary tumor cell lines (AtT20 and GH3 cells) with a focus on corticotroph adenoma cells. METHODS: Reverse transcription polymerase chain reaction and enzyme-linked immunosorbent assay were conducted with AtT20 cells to confirm the effects of OXT on hormonal activity; flow cytometry was used to assess changes in the cell cycle after OXT treatment. Moreover, the impact of OXT on proliferating cell nuclear antigen (PCNA), nuclear factor κB, and mitogen-activated protein kinase signaling pathway was analyzed by Western blot. RESULTS: OXT treatment of 50 nM changed the gene expression of OXT receptor and pro-opiomelanocortin within a short time. In addition, OXT significantly reduced adrenocorticotropic hormone secretion within 1 hour. S and G2/M populations of AtT20 cells treated with OXT for 24 hours were significantly decreased compared to the control. Furthermore, OXT treatment decreased the protein levels of PCNA and phosphorylated extracellular-signal-regulated kinase (P-ERK) in AtT20 cells. CONCLUSION: Although the cytotoxic effect of OXT in AtT20 cells was not definite, OXT may blunt cell proliferation of corticotroph adenomas by altering the cell cycle or reducing PCNA and P-ERK levels. Further research is required to investigate the role of OXT as a potential therapeutic target in corticotroph adenomas.

We describe a case of spontaneous bleeding from a branch of the right internal pudendal artery that resulted in massive scrotal swelling in a patient who had underwent primary percutaneous coronary intervention with the use of abciximab concurrent with conventional anticoagulation and dual antiplatelet therapies for the treatment of acute ST-segment elevation myocardial infarction. This unusual complication was promptly identified by percutaneous peripheral arteriography and successfully treated with gel-foam embolization.

PURPOSE: To describe early macular hole (MH) development in rhegmatogenous retinal detachment (RRD) after scleral buckling (SB) based on optical coherence tomography (OCT) findings. METHODS: The medical records and spectral domain OCT images of patients in whom MH developed after RRD repair were evaluated retrospectively. RESULTS: A postoperative MH was detected in five eyes that underwent SB during a 6-year period. All had fovea-off RRD without MH at the time of surgery. OCT showed partial loss of the inner retina with a preserved photoreceptor layer in early postoperative days. On average, 7 days (range,5 to 8 days) after surgery, outer retinal tissues disappeared, resulting in the full-thickness MH. CONCLUSIONS: Serial OCT findings revealed that partial-thickness lamellar holes progressed to full-thickness MHs, which were formed by the degeneration of the outer retina in eyes with preceding loss of the glial cone in the fovea.

Exercise-induced ischemic ST responses were analyzed in 36 patients who presented with chest pain and had exercise test and the results were compared with their coronary angiographic findings. Among 36 exercise test positives, the incidences of one-, two- and three vessel disease, and left main disease were 25%(9 cases), 30%(11 cases), 25%(9 cases) and 9%(3 cases), respectively. The incidence of multivessel disease(i.e., two-to three vessel disease or left main disease) in patients with ST depression > or =2.0mm was 72% and that in those with ST depression of 1.0-1.9mm was 45%. In patients with downsloping ST depression, the incidence of multivessel disease was significantly higher than that of one vessel disease(86% vs 14%, p<0.001). But both incidences of one vessel disease and multivessel disease were similar in patients with flat and slowly upsloping ST depression. More than two thirds of patients with ischemic ST depression appearing in the first 6 minutes of exercise or those lasting past 7 minutes in recovery were associated with multivessel disease. It is concluded that attention to depth, type, appearance time and duration of ST depression during exercise test is particularly helpful in detecting patients with advanced coronary disease.

The polymorphism at codon 129 (M129V) of the human prion protein gene (PRNP) is a known risk factor for Creutzfeldt-Jakob disease (CJD) in Caucasians. There are few reports of this polymorphism's effect on memory and on the risk of Alzheimer's disease (AD). The M129V genotype distributions among Asians are very different from Caucasians. Another polymorphism, codon 219 (E219K) is not found in Caucasians. We investigated two polymorphisms of PRNP, M129V (rs1799990) and E219K (rs1800014) in 297 Korean AD patients and 217 healthy subjects. The analysis of the genotype and allele distributions showed no significant difference between the AD patients and the controls in both polymorphisms (P=0.19 genotype, P=0.51 allele for M129V; P=0.64 genotype, P=0.50 allele for E219K). Also, the PRNP polymorphisms were not significantly associated with AD when the populations were stratified for the presence or absence of apolipoprotein E-e4 (ApoE-epsilon4) allele. These results suggest that the PRNP genetic variants are not associated with the risk for AD in Korean population.

PURPOSE: The aim of this study was to identify a role for endodontic intervention in enhancing the regenerative potential of the periodontal ligament when combined with periodontal treatment in seriously involved teeth with a secondary endodontic component. METHODS: Patients who exhibited radiolucency extending to the periapical region, abnormal electric pulp testing values, and deep probing depth derived from primary periodontal disease with secondary endodontic involvement were included. Intentional root canal treatment was applied to those teeth in which the apical lesions were presumed to communicate with those of the periodontal lesion of the teeth that remained vital. In all three selected cases, regenerative periodontal therapy incorporating either bone graft or guided tissue regeneration was instituted 3 months after the endodontic intervention. RESULTS: Remarkable enhancement in radiographic density was noticeable around the affected teeth as evidenced by changes in radiopacity. There was a significant reduction in the probing pocket depth and gain in the clinical attachment level. Chewing discomfort gradually disappeared from the commencement of the combined treatment. CONCLUSIONS: An intentional endodontic intervention may be a worthwhile approach for the sophisticated management of teeth suffering from serious attachment loss and alveolar bone destruction with concomitant secondary endodontic involvement.
