Antenatal myomectomy of huge pedunculated fibroid.

A female patient in her 20s presented at 10 weeks of pregnancy with abdominal pain. She was known to have a 17-cm fibroid a year ago, which, on repeat imaging, was found to have increased in size to 29 cm. A 12-cm increase in size over a year therefore led to concerns that it would increase in pregnancy, causing risk of thrombosis, decrease in venous return, miscarriage, fibroid torsion, fibroid necrosis, preterm labour and uterine rupture. Following a multidisciplinary team review with obstetricians, neonatologists, gynaecologists and radiologists, the patient opted to proceed with an open myomectomy at 14 weeks gestation, which was performed successfully. The pregnancy continued uneventfully until term when she delivered a healthy girl infant at 38+2 weeks via an elective caesarean section.

The role of iron in the pathogenesis of endometriosis: a systematic review.

STUDY QUESTION: What is the role of iron in the pathophysiology of endometriosis? SUMMARY ANSWER: Iron excess is demonstrated wherever endometriotic tissues are found and is associated with oxidative stress, an inflammatory micro-environment, and cell damage; the iron-mediated oxidative stress is independently linked to subfertility, symptom severity, and malignant transformation. WHAT IS KNOWN ALREADY: Iron is found in excess in endometriotic tissues, and multiple mechanisms have been studied and posited to explain this. It is clear that iron excess plays a vital role in promoting oxidative stress and cell damage. The evidence base is large, but no comprehensive reviews exist to summarize our understanding and highlight the overarching themes to further our understanding and suggest future directions of study for the field. STUDY DESIGN SIZE DURATION: This systematic review with a thematic analysis retrieved studies from the PubMed, Embase, Web of Science, and Cochrane Library databases and searches were conducted from inception through to August 2022. Human and animal studies published in the English language were included and identified using a combination of exploded MeSH terms ('Iron' and 'Endometriosis') and free-text search terms ('Iron', 'Ferric', 'Ferrous', 'Endometriosis', 'Endometrioma'). PARTICIPANTS/MATERIALS SETTING METHODS: This review was reported in accordance with the PRISMA guidelines. All studies reporting original data concerning the role of iron or iron complexes in the pathophysiology of endometriosis were included. Studies that did not report original data or provided a review of the field were excluded. Bias analysis was completed for each included study by using the Newcastle-Ottawa scoring system. MAIN RESULTS AND THE ROLE OF CHANCE: There were 776 records identified and these were screened down to 53 studies which met the eligibility criteria, including 6 animal and 47 human studies, with 3556 individual participants. Iron excess is demonstrated in various tissues and fluids, including ovarian endometriomas, ovarian follicles, ectopic endometriotic lesions, and peritoneal fluid. Markers of oxidative stress are strongly associated with high iron levels, and aberrant expression of iron-transport proteins has been demonstrated. Abnormal resistance to ferroptosis is likely. Iron-mediated oxidative stress is responsible for a pro-inflammatory micro-environment and is linked to subfertility, symptom severity, and, possibly, malignant transformation. LIMITATIONS REASONS FOR CAUTION: A minority of the included studies were of objectively low quality with a high risk of bias and may lead to misleading conclusions. Additionally, multiple studies failed to appropriately characterize the included patients by known confounding variables, such as menstrual cycle phase, which may introduce bias to the findings. WIDER IMPLICATIONS OF THE FINDINGS: Current literature depicts a central role of aberrant iron mechanics and subsequent oxidative stress in endometriosis. It is likely that iron excess is at least partly responsible for the persistence and proliferation of ectopic endometriotic lesions. As such, iron mechanics represent an attractive target for novel therapeutics, including iron chelators or effectors of the iron-oxidative stress pathway. There are significant gaps in our current understanding, and this review highlights and recommends several topics for further research. These include the role of iron chelation, resistance to ferroptosis, the relationship between iron excess and localized hypoxia, systemic iron pathophysiology in endometriosis, and the role of oxidative stress in malignant transformation.

Vascularisation in Deep Endometriosis: A Systematic Review with Narrative Outcomes.

Deep endometriosis (DE) is the most severe subtype of endometriosis, with the hallmark of lesions infiltrating adjacent tissue. Abnormal vascularisation has been implicated in contributing to endometriosis lesion development in general, and how vascularisation influences the pathogenesis of DE, in particular, is of interest. This systematic review followed the PRISMA guidelines to elucidate and examine the evidence for DE-specific vascularisation. A literature search was performed using MEDLINE, Embase, PubMed, Scopus, Cochrane CENTRAL Library and Europe PubMed Central databases. The databases were searched from inception to the 13 March 2023. A total of 15 studies with 1125 patients were included in the review. The DE lesions were highly vascularised, with a higher microvessel density (MVD) than other types of endometriotic lesions, eutopic endometrium from women with endometriosis and control tissue. Vascular endothelial growth factor, its major subtype (VEGF-A) and associated receptor (VEGFR-2) were significantly increased in the DE lesions compared to superficial endometriosis, eutopic endometrium and control tissue. Progestin therapy was associated with a significant decrease in the MVD of the DE lesions, explaining their therapeutic effect. This review comprehensively summarises the available literature, reporting abnormal vascularisation to be intimately related to the pathogenesis of DE and presents potentially preferential therapeutic targets for the medical management of DE.

Ruptured chronic ectopic pregnancy presenting with a negative urine pregnancy test.

An acute ectopic pregnancy is one of the most common gynaecological emergencies in clinical practice. The diagnosis is usually established by a combination of clinical examination findings, correlated with sonographic and laboratory results. However, a chronic ectopic pregnancy (CEP) may occur when the ectopically implanted gestation, mostly in the fallopian tubes, invades the underlying structures, causing protracted destruction at the site of implantation. Individuals may present with subacute or chronic abdominal pain, abnormal vaginal bleeding, amenorrhoea and a low bHCG. The correct diagnosis is often only established following laparoscopy or even histologically after the operation. The authors present the case of a woman in her 30 s presenting with severe right sided abdominal pain and a failing pregnancy at 10 weeks gestation. Her urine pregnancy test was negative, but her serum bHCG was 18 IU/L. A transvaginal ultrasound scan confirmed a ruptured right tubal ectopic pregnancy. A laparoscopic salpingectomy was performed. This case provides an important reminder that a CEP should always be considered in the differential diagnosis of women of reproductive age presenting with acute lower abdominal pain, despite a negative urine pregnancy test.

Dermatomyositis as a paraneoplastic phenomenon in ovarian cancer.

A 60-year-old woman diagnosed with papillary serous ovarian cancer had Klean-Prep and MRI contrast preoperatively. Afterwards, she developed swelling and an urticarial rash around her eye as she proceeded to have planned debulking surgery. Postoperatively the swelling and rash had spread over her face, neck, back and chest. Dermatology advised a possible allergy to Klean-Prep and MRI contrast. Subsequently over the next few months, the patient became severely debilitated from proximal myopathy of the upper and lower limbs, suffered severe pain restricting mobility and small bowel obstruction. Medical oncologist reviewed the patient, clinically diagnosed dermatomyositis and initiated treatment with high-dose intravenous steroids, resulting in remission of the patient's condition. The main purpose of this study is to describe the severity, diagnostic challenges and underline the clinical significance of dermatomyositis manifestations as a paraneoplastic effect in patients with ovarian cancer.

Concurrent emphysematous cholecystitis and emphysematous cystitis in a non-diabetic patient.

Emphysematous cholecystitis and emphysematous cystitis occurring concurrently has not been reported before. This article discusses a non-diabetic patient suffering from both these conditions concurrently with Escherichia coli as the causative organism - a first in the medical literature.

Massive Small Bowel Infaction: A Comparison of Two Cases.

We present two similar cases of massive small bowel infarction in which two different surgical approaches were employed, illustrating the advantages of the staged approach of damage control surgery. This comprises an initial operation, limited to bowel resection and temporary closure of the bowel ends, and a second performed after 48 to 72 hours where the bowel continuity is re-established. We strongly advocate such an approach as it appears to offer a quicker recovery with fewer complications.

Multiple bilateral choroidal metastasis from anal melanoma.

A 58-year-old Caucasian woman with bleeding per rectum had a melanoma of the anal canal. She subsequently presented with visual disturbance and was noted to have bilateral multiple choroidal metastasis, along with other multiple systemic metastases. Orbital radiotherapy led to near complete resolution of the ocular metastasis.
