Objective To analyze the effects of immediate multi-vessel percutaneous coronary inter-vention(MV-PCI)and staged vascular intervention(Staged-PCI,immediate PCI for culprit-only followed by a delayed treatment of all other lesions)on the prognosis in elderly patients with acute ST-segment elevation myocardial infarction(STEMI).Methods A total of 417 elderly acute STEMI patients who underwent PCI in Baoding First Central hospital from January 2021 to June 2023 were enrolled,and according to different treatment strategies,they were divided into MV-PCI group(87 cases)and Staged-PCI group(330 cases).A propensity score matching(PSM)model was established based on baseline data of the two groups,there were 84 cases in each group.During a mean follow-up period of 13.5 months,with the occurrence of main adverse cardi-ovascular and cerebrovascular events(MACCE)as endpoint,the incidence of MACCE was com-pared between the two groups after PSM.Cox proportional hazard regression model was used to analyze the risk factors of MACCE.Results Before PSM,there were significant differences be-tween the two groups in terms of age,proportions of hypertension,diabetes and hyperlipidemia,family history,stroke history,peripheral artery disease,preoperative SBP,lesion vessels(such as left anterior descending branch and left circumflex branch),and number of non-diseased vessels(P＜0.05).Kaplan-Meier survival curve showed that the incidences of MACCE and all-cause mor-tality were significantly lower in the MV-PCI group than the Staged PCI group(Plog rank＜0.05).Multivariate Cox proportional hazard regression model showed that MV-PCI was a protective prognostic factor for MACCE(HR=0.263,95％CI:0.105-0.659,P=0.004)and all-cause death(HR=0.236,95％CI:0.007-0.722,P=0.016).Conclusion MV-PCI can significantly improve the prognosis of elderly patients with acute STEMI with multivessel disease.

BACKGROUND: Minocycline-induced pigmentation of bone (black bone) is well described in tooth-bearing intra-oral bone, but is less known in periarticular bone in patients who have undergone total joint arthroplasty. On a retrospective basis, we investigated the short-term clinico-radiological results of total joint arthroplasties in which the patient developed minocycline-induced periarticular black bone. METHODS: We found 5 cases (0.08%), in 4 patients, of periarticular bone pigmentation revealed during total joint arthroplasties (2 hips, 2 knees, and 1 ankle) in our series of total joint surgeries (6,548 cases) over a 10-year time period in our 3 institutes. Their mean age was 56 years at surgery. All patients had received long-term minocycline treatment. Mean dosage and duration of minocycline was 160 mg/day and 2.2 years, respectively. Minocycline had been prescribed for reactive arthritis (one), rheumatoid arthritis (two) and late infection after total joint arthroplasty (two patients). Mean follow-up period was 3.4 years after the surgeries. RESULTS: All cases had black or brown pigmentation in the periarticular bones during the surgery. There was no pigmentation in the cartilage or soft tissues of the joints. The mean Japanese Orthopaedic Association (JOA) score or Japanese Society for Surgery of the Foot (JSSF) scale for rheumatoid arthritis foot and ankle joints at latest follow-up (case 1, 66; case 2, 87; case 3, 77; case 4, 77; case 5, 80) improved compared to those of pre-surgery (case 1, 47; case 2, 45; case 3, 55; case 4, 34; case 5, 55). No implant loosening was noted on radiographic examination during the follow-up period. No abnormal bone formation, bone necrosis, hemosiderin deposition, malignancy or metallic debris was found on histological examination. CONCLUSIONS: No clinico-radiological symptoms of total joint arthroplasties showed in the patients with minocycline-induced periariticular black bone in the short-term. Systemic minocycline treatment has the potential to induce significant black pigmentation of many tissues. In particular, minocycline-induced pigmentation of periarticular bone may be accelerated by inflammation due to rheumatic or pyogenic arthritis. Surgeons should recognize the risk of bone pigmentation in inflamed joints due to the systemic treatment of minocycline and explore its influence on periarticular bone and total joint arthroplasty in the long-term.

OBJECTIVE: The study was designed to ascertain a proper method of early diagnosis and treatment of ectopic pregnancy by analyzing its clinical and epidemiological characteristics. METHODS: The medical records of patients who were diagnosed to ectopic pregnancy at Hallym medical center during the period from January 1, 2000 to December 31, 2007 have been reviewed. RESULTS: The incidence of ectopic pregnancy was 7.3% (1,067) out of 14,519 deliveries. The most frequent age group was 26~30 (29.5%). Risk factors they had were previous histories of abdominal or pelvic surgery (37.0%), artificial abortion (30.8%), pelvic inflammatory disease (12%), and tubal sterilization (9.6%). Most frequent clinical symptoms were amenorrhea (88.7%), lower abdominal pain (81.2%), and vaginal spotting (60.0%). Percentage of patients with hemoglobin level over 10.0 gm/dL was 79% and below 8.0 gm/dL 3.9%. The clinical symptoms of ectopic pregnancy most commonly occurred after 6~8 weeks from last menstrual period (47%). Ectopic gestation was implanted on the fallopian tube in 89%, cornus in 7.2%, ovary in 1.1% and the cervix in 2.7%. Laparosopic surgeries were performed in 755 cases (71.6%) and laparotomies in 273 cases (25.9%) and dilatation and curettages in 26 cases (2.5%). Salpingectomy was performed most frequently (82.4%). Methotrexate (MTX) treatment was successful in 13 cases (1.21%). CONCLUSION: The early diagnosis of ectopic pregnancy is most useful when serum beta-hCG and vaginal sonography are used together. Laparoscopy would be a preferred method because of its short hospitalization period and low complication rate compared with laparotomy in ectopic pregnancy treatment.
