Pathological Discrepancy: Simple Mesenteric Cyst vs. Mesenteric Lymphangioma.

INTRODUCTION: Both mesenteric cysts and cystic lymphangiomas are scarce and clinically and radiologically almost identical derivatives, but their histological structure is fundamentally different. Case Presentation. A 52-year-old woman was consulted by a surgeon for a derivative felt in her abdomen. The patient said she felt a growing derivative in the abdomen about a month ago. After consulting and testing, a sigmoid colon mesenteric cyst (13 cm × 11 cm × 10 cm) was found. Complete excision of the cyst within healthy tissues was performed through laparotomy. The surgery had no complications. The initial pathological answer was a simple mesothelial cyst (a rare histological finding). However, immunohistochemical tests were performed that showed that diagnosis was mesenteric cystic lymphangioma (ML). Cystic lymphangiomas that have a link to the mesentery have been described less than 200 times. CONCLUSIONS: Final differential diagnosis between different cystic derivatives is possible only based on histopathological examinations. Mesenteric lymphangioma is most common at a very young age, but in rare cases, it also occurs in adults. All clinicians should increase their awareness of the disease.

Intrauterine device migration into the lumen of large bowel: A case report.

INTRODUCTION: Colon perforation caused by the intrauterine device (IUD) migration is rare, but severe complication that can occur years after the insertion. Depending on the location of the injured intestine, the different methods for extracting migrated IUD raging from colonoscopy to laparotomy can be chosen. CASE PRESENTATION: A 41-year-old female presented with the discomfort in the epigastric area went to the outpatient clinic. A doctor performed gastroscopy and found a polyp. During a colonoscopy, we found a small solid object protruding through the intestinal wall. CT scan showed IUD like "T" shape foreign body, which longest part was protruding a wall of the colon. After these CT findings, the patient informed us that she had IUD inserted almost ten years ago. We found the device with the laparoscopic approach. IUD was removed and the intestinal damage was repaired during the mini-laparotomy. CONCLUSIONS: Perforation of IUD can be asymptomatic, although sometimes it can cause short-term or long-term symptoms. Penetrated IUDs should be removed whenever identified. For intra-abdominal penetrations, the laparoscopic or mini-laparotomy approach is a safe and appropriate method.

Perish or Publish Dilemma: Challenges to Responsible Authorship.

Controversies related to the concept and practice of responsible authorship and its misuse have been among the most prominent issues discussed in the recent literature on research integrity. Therefore, this paper aims to address the factors that lead to two major types of unethical authorship, namely, honorary and ghost authorship. It also highlights negative consequences of authorship misuse and provides a critical analysis of different authorship guidelines, including a recent debate on the amendments of the International Committee of Medical Journal Editors (ICMJE) authorship definition. Empirical studies revealed that honorary authorship was the most prevalent deviation from the responsible authorship standards. Three different modalities of honorary authorship were distinguished: gift authorship, guest authorship, and coercive authorship. Prevalence of authorship misuse worldwide and in Europe was alarmingly high, covering approximately one third of all scientific publications. No significant differences were reported in authorship misuse between different health research disciplines. The studies conducted in North America highlighted the most effective means to cope with unethical authorship. These were training in publishing ethics, clear authorship policies developed by medical schools, and explicit compliance with the authorship criteria required by the medical journals. In conclusion, more empirical research is needed to raise awareness of the high prevalence of authorship misuse among scientists. Research integrity training courses, including publication ethics and authorship issues should be integrated into the curricula for students and young researchers in medical schools. Last but not least, further discussion on responsible authorship criteria and practice should be initiated.
