Ectopic pregnancy is a common medical problem that is difficult to diagnose and potentially may lead to significant mortality or morbidity. The incidence of ectopic pregnancy is definitely increasing due to the rise in pelvic inflammatory disease (PID), pelvic surgery, intrauterine device (IUD), and assisted reproductive technologies, such as in vitro fertilization and embryo transfer (IVF-ET). Combined ectopic gestations are much rare and their true incidence is unknown. Multiple ectopic gestations may occur in a variety of locations. The majority involve one or both fallopian tubes. We report a case of combined tubal and cervical pregnancies, and discuss their management.

Myotonic dystrophy is a multisystemic disorder inherited as an autosomal dominant trait. The characteristic clinical features include the presence of myotonia, atrophy of the muscles of the face and the sternocleidomastoids and numerous nonmusclar manifestations such as cataracts, frontal baldness, gonadal dysfunctions and cardiac abnormalities. We experienced one case of myotonic dystrophy with prolonged atrial flutter in 30-year-old male who was admitted because of palpitation. We present this case with reviewing literatures.

Fibromatosis is generally a benign tumor that arises from the musculoaponeurotic tissues of the body, rarely occurring in the head and neck region. This can be treated with a good prognosis, but sometimes recurs as a local invasion. Preoperative core needle biopsy and MR images are necessary to diagnose preoperatively and outline the tumor extent. The mainstay of treatment is complete surgical excision. Nonetheless, an excision is often difficult because of the complex anatomy or proximity of the tumor to vital structures in the head and neck region. We report a rare case of desmoid-type fibromatosis that occurred in the neck, closely attached to the transverse process of the cervical vertebra. The present article covers an extensive analysis of the case with a review of the related literature.

Journal of Korean Medical Science 2023;38(11):e94-
Background:
Owing to limited experience with the new vaccine platforms, discussion of vaccine safety is inevitable. However, media coverage of adverse events of special interest could influence the vaccination rate; thus, evaluating the outcomes of adverse events of special interest influencing vaccine administration is crucial.
Methods:
We conducted regression discontinuity in time analysis to calculate the local average treatment effect (LATE) using datasets from Our World in Data and Johns Hopkins University Center for Systems Science and Engineering. For the United States, the United Kingdom, and Europe, the cutoff points were April 23rd and June 23rd, April 7th, and the 14th week of 2021, respectively.
Results:
The LATE of the Advisory Committee on Immunization Practices (ACIP) meeting held on April 23rd was −0.249 for all vaccines, −0.133 (−0.189 to −0.076) for Pfizer, −0.064 (−0.115 to −0.012) for Moderna, and −0.038 (−0.047 to −0.030) for Johnson & Johnson. Discontinuities were observed for all three types of vaccines in the United States. The June 23rd meeting of the ACIP (mRNA vaccines and myocarditis) did not convene any discontinuities. Furthermore, there was no significant drop in the weekly average vaccination rates in Europe following the European Medicines Agency (EMA) statement on April 7th. Conversely, there was a significant drop in the first-dose vaccination rates in the United Kingdom related to the EMA report. The first-dose vaccination rate for all vaccines changed by −0.104 (−0.176 to −0.032).
Conclusion
Although monitoring and reporting of adverse events of special interest are important, a careful approach towards public announcements is warranted.

Purpose:
This study aims to evaluate the incidence and management of venous ruptures after percutaneous transluminal angioplasty (PTA) for dysfunctional arteriovenous (AV) access.
Materials and Methods:
From January 1998 to December 2015, 13506 PTA, mechanical thrombectomy, and thrombolysis procedures were performed in 6732 patients. The venous rupture rate following PTA was obtained, and access circuit primary patency (ACPP) was compared according to the etiology (PTA, thrombotic occlusion, and treatment type) of the venous rupture present.
Results:
Venous rupture developed in 604 of the 13506 procedures. Venous ruptures were more frequent in female, AV graft cases, and in cases accompanied by thrombosis. Balloon tamponade was performed in 604 rupture cases, and stents were deployed in 119 cases where contrast extravasation and flow stasis persisted. ACPP was significantly better in the non-ruptured AV access circuits than in the ruptured group. However, AV access type and thrombosis was not associated with primary patency. In ruptured cases, ACPP is 8.4 months for prolonged balloon tamponade and 11.2 months for bare-metal stent insertion, showing statistically significant difference.
Conclusion
Balloon tamponade and bare-metal stent placement are effective treatment for PTA-induced venous ruptures. In particular, stent placement showed a similar ACPP to that of non-ruptured AV access circuits.

Clinics in Orthopedic Surgery 2021;13(4):520-528
Background:
Although the effectiveness of acromioplasty is controversial, it is commonly performed during rotator cuff repair to reduce external impingement. During follow-up, osteolysis under the acromion (acromial cupping) could be observed. However, this phenomenon has been rarely addressed in the literature. The purpose of this study was to compare the prevalence and severity of acromial cupping after rotator cuff repair depending on the concomitant performance of acromioplasty and evaluate the influence of acromial cupping on clinical and radiological outcome.
Methods:
This is a retrospective study involving patients who underwent arthroscopic rotator cuff repair for small-to-large fullthickness rotator cuff tears from October 2015 to March 2019 and clinical follow-up and magnetic resonance imaging at least 1 year postoperatively. A total of 110 patients were enrolled and divided into two groups depending on whether acromioplasty had been performed (group A) or not (group N). The prevalence of acromial cupping was evaluated in each group. In addition, we stratified patients according to the severity of acromial cupping to investigate its influence on healing and functional scores (visual analog scale [VAS], American Shoulder and Elbow Surgeons [ASES] score, simple shoulder test [SST], and Constant-Murley score).
Results:
There were 85 patients in group A and 25 patients in group N. The prevalence of acromial cupping and acromial cysts was as follows: 36.4% (40 patients) and 6.4% (7 patients), respectively, in the total subjects; 43.5% (37/85) and 5.9% (5/85), respectively, in group A; and 12.0% (3/25) and 8.0% (2/25), respectively, in group N. The prevalence of acromial cupping was significantly different between the two groups (p = 0.012). However, functional outcomes were not significantly different between groups stratified by the severity of acromial cupping (VAS, p = 0.464; ASES score, p = 0.902; SST, p = 0.816; and Constant-Murley score, p = 0.117). The difference in healing rate was statistically insignificant between groups (p = 0.726).
Conclusions
The incidence and severity of acromial cupping were significantly greater in patients who underwent rotator cuff repair with acromioplasty. It was a relatively common phenomenon, especially after acromioplasty. However, neither the existence nor the severity of acromial cupping affected functional outcomes or healing.
