[Suspected autoimmune coagulation factor IX deficiency difficult to diagnose due to concurrent lupus anticoagulant]

A woman in her 70s who was undergoing treatment for an overlap syndrome of autoimmune hepatitis and primary biliary cirrhosis developed persistent genital bleeding. Coagulation tests revealed a longer activated partial thromboplastin time, a 7% decrease in coagulation factor IX activity (FIX:C) and a FIX inhibitor (of 3 BU/ml). Lupus anticoagulant (LA), anticardiolipin antibody, and anti-β2 glycoprotein I antibody were positive, and the activated partial thromboplastin time cross-mixing test suggested the presence of LA. Additionally, all intrinsic coagulation factors decreased, but activity of all factors except FIX showed dilution linearity, which suggested a false decrease in activity due to LA. Although definitive diagnosis was difficult due to concurrent LA, this case was strongly suspected to be autoimmune coagulation FIX deficiency complicated by LA. Bypass therapy was not performed because the patient had no anemia and was positive for LA, and immunosuppressive therapy with prednisolone was initiated immediately. Eleven weeks after diagnosis, FIX:C was 41% and zFIX inhibitor was less than 1 BU/ml, leading to remission.

Sexual Abuse as a Cause of Prepubertal Genital Bleeding: Understanding the Role of Routine Physical Examination

Although accidental trauma is the most common mechanism for genital bleeding, sexual abuse should be considered when the patient is prepubertal and/or a vague history of bleeding is provided. Prepubertal female genital exams should be completed routinely; this clinical technique is critical for pediatricians to assess pubertal progression, to identify pathologies or differences in sexual differentiation, and to narrow a broad differential diagnosis of bleeding. Physical evidence of sexual abuse on exam is rarely found, and therefore the diagnosis relies on a child's disclosure. Physicians should be cognizant of barriers to patient disclosure. In this commentary we aim to provide general pediatricians and trainees with a framework for evaluating genital/vaginal bleeding in prepubertal girls, by discussing the following: (1) the importance of a complete anogenital exam in generating a differential diagnosis; and (2) the possibility of sexual abuse as an etiology with recognition that the disclosure process is complex.

Risk factors for spontaneous miscarriage above 12 weeks or premature delivery in patients undergoing cervical polypectomy during pregnancy

Background

It currently remains unknown whether the resection of cervical polyps during pregnancy leads to miscarriage and/or preterm birth. This study evaluated the risk of spontaneous PTB below 34 or 37 weeks and miscarriage above 12 weeks in patients undergoing cervical polypectomy during pregnancy.

Methods

This was a retrospective monocentric cohort study of patients undergoing cervical polypectomy for clinical indication. Seventy-three pregnant women who underwent polypectomy were selected, and risk factors associated with miscarriage above 12 weeks or premature delivery below 34 or 37 weeks were investigated. A multivariable regression looking for predictors of spontaneous miscarriage > 12 weeks and PTB < 34 or 37 weeks were performed.

Results

Sixteen patients (21.9%, 16/73) had spontaneous delivery at < 34 weeks or miscarriage above 12 weeks. A univariate analysis showed that bleeding before polypectomy [odds ratio (OR) 7.7, 95% confidence interval (CI) 1.6–37.3, p = 0.004], polyp width ≥ 12 mm (OR 4.0, 95% CI 1.2–13.1, p = 0.005), the proportion of decidual polyps (OR 8.1, 95% CI 1.00–65.9, p = 0.024), and polypectomy at ≤10 weeks (OR 5.2, 95% CI 1.3–20.3, p = 0.01) were significantly higher in delivery at < 34 weeks than at ≥34 weeks. A logistic regression analysis identified polyp width ≥ 12 mm (OR 11.8, 95% CI 2.8–77.5, p = 0.001), genital bleeding before polypectomy (OR 6.5, 95% CI 1.2–55.7, p = 0.025), and polypectomy at ≤10 weeks (OR 5.9, 95% CI 1.2–45.0, p = 0.028) as independent risk factors for predicting delivery at < 34 weeks. Polyp width ≥ 12 mm and bleeding before polypectomy are risk factors for PTB < 37 wks.

Conclusions

Our cohort of patients undergoing polypectomy in pregnancy have high risks of miscarriage or spontaneous premature delivery. It is unclear whether these risks are given by the underlying disease, by surgical treatment or both. This study establishes clinically relevant predictors of PTB are polyp size> 12 mm, bleeding and first trimester polypectomy. PTB risks should be exposed to patients and extensively discussed with balancing against the benefits of intervention in pregnancy.

Medical Child Abuse: A Case Presenting as Anogenital Bleeding of Unknown Origin in an Older Child

BACKGROUND

Medical child abuse is a challenging diagnosis to make, particularly in older children with unusual presenting symptoms.

CASE

A 7-year-old child with complex medical history presented with anogenital bleeding of unknown origin. Extensive laboratory testing, imaging studies, and diagnostic procedures were negative for any etiology. Forensic testing confirmed the blood in her underwear was a genetic match to the patient. Trial separation from the mother was diagnostic and therapeutic in this case.

SUMMARY AND CONCLUSION

Older children who are victims of medical child abuse might present in a variety of ways, and might even collaborate with the perpetrator in falsifying symptoms. It is important to keep medical child abuse on the differential when the patient's symptoms and work-up do not match.

New hemostatic method using Mohs' paste for fatal genital bleeding in advanced cervical cancer

► Mohs' paste is made of a mixture of zinc chloride paste. ► Recent reports show that hemostasis could be achieved in various kinds of cancer. ► Mohs' paste can save a patient's life from fatal genital bleeding.
