INTRODUCTION: Congenital variants of the cervical spine may mimic traumatic lesions and may cause recurrent episodes of pain. The spectrum of cervical variants includes persistent apophyses of the transverse processes, persistent epiphyses, vertebral platyspondylia, vertebral hypoplasia, and dysplasia of the vertebral arch. Furthermore, abnormalities of the spinous process have been described including doubled spinous processes and hypertrophies. Unilateral hyperplasia of a spinous process is a rare finding that has only been described rarely as case reports...

Human papillomavirus (HPV) was found to be the causative agent for cervical cancer in the 1980s with almost 100% of cervical cancer cases testing positive for HPV. Since then, many studies have been conducted to elucidate the molecular basis of HPV, the mechanisms of carcinogenesis of the virus, and the risk factors for HPV infection. Traditionally, the Papanicolaou test was the primary screening method for cervical cancer. Because of the discovery and evolving understanding of the role of HPV in cervical dysplasia, HPV testing has been recommended as a new method for cervical cancer screening by major professional organizations including the American Cancer Society, American Society for Colposcopy and Cervical Pathology, and the American Society for Clinical Pathology...

INTRODUCTION: Large loop excision of the transformation zone (LLETZ) is a common gynecological treatment for cervical dysplasia but can be challenging to teach. There is no widely adopted simulator for this procedure in Australia, so a new low-fidelity simulator was designed and evaluated. METHOD: A simulator for a LLETZ procedure was developed. Doctors (N = 29), varied in experience level in gynecology at a tertiary hospital, performed a LLETZ procedure using the simulator...

BACKGROUND: The Bethesda System uses a two-tiered approach in the diagnosis of cervical squamous intraepithelial lesions (SILs). Occasionally, Papanicolaou (Pap) tests with evident low-grade SIL (LSIL) also have some features suggestive but not diagnostic of high-grade SIL (HSIL). This study reviews our experience with "Low-grade Squamous Intraepithelial Lesion, Cannot Exclude High-grade" (LSIL-H) and discusses the best approach to report such Paps if the LSIL-H interpretation is abandoned...

Cervical cancer is one of the most common types of cancer in women worldwide. Most deaths due to the disease occur in less developed areas of the world. In this work, we introduce a new image dataset along with expert annotated diagnoses for evaluating image-based cervical disease classification algorithms. A large number of Cervigram(®) images are selected from a database provided by the US National Cancer Institute. For each image, we extract three complementary pyramid features: Pyramid histogram in L*A*B* color space (PLAB), Pyramid Histogram of Oriented Gradients (PHOG), and Pyramid histogram of Local Binary Patterns (PLBP)...

BACKGROUND: Preterm birth (PTB) is the leading cause of neonatal morbidity and mortality in non-anomalous neonates in the US. Women with a previous early spontaneous PTB are at highest risk for recurrence. Weekly intramuscular 17-alpha hydroxyprogesterone caproate (17-OHPC) reduces the risk of recurrent prematurity. Though current guidelines recommend 17-OHPC initiation between 16-20 weeks', in clinical practice, 17-OHPC is started across a spectrum of gestational ages. OBJECTIVE: To examine the relationship between the gestational age at 17-OHPC initiation and recurrent PTB among women a prior spontaneous PTB 16-28 weeks' gestation...

Mucosal exposure to human papillomavirus (HPV) can lead to anogenital and head and neck (H&N) cancer. Vaccination at a young age can be almost 100% effective in preventing HPV infection with the viral subtypes in both men and women, at least for disease in the anogenital tract. Therapeutic strategies targeting HPV in cervical dysplasia and cancer are showing promise as well in regressing dysplasia and controlling disease. That HPV-positive H&N cancer is a different disease from HPV-negative disease, with different molecular and clinical features and prognosis, is becoming better appreciated...

WHIM syndrome is a condition in which affected persons have chronic peripheral neutropenia, lymphopenia, abnormal susceptibility to human papilloma virus infection, and myelokathexis. Myelokathexis refers to the retention of mature neutrophils in the bone marrow (BM), which accounts for degenerative changes and hypersegmentation. Most patients present heterozygous autosomal dominant mutations of the gene encoding CXCR4. Consequently, aberrant CXCL12/CXCR4 signaling impairs the receptor downregulation causing hyperactivation (gain-of-function) that affects BM homing for myelopoiesis and lymphopoiesis and the release of neutrophils in the bloodstream...

Aerobic vaginitis (AV) is the name given in 2002 to a vaginal infectious entity which was not recognized as such before. It is characterized by abnormal (dysbiotic) vaginal microflora containing aerobic, enteric bacteria, variable levels of vaginal inflammation and deficient epithelial maturation. Although AV and bacterial vaginosis (BV) share some characteristics, such as a diminished number or absence of lactobacilli, increased discharge (fishy smelling in BV, while in severe forms of AV, a foul, rather rotten smell may be present) and increased pH (often more pronounced in AV), there are also striking differences between the two...

BACKGROUND: The impact of fewer than 3 doses of human papillomavirus (HPV) vaccine on genital warts is uncertain. METHODS: Using the Truven Health Analytics Marketscan administrative database, we compared rates of genital warts among women receiving 0, 1, 2, or 3 doses of HPV vaccine. Females aged 9 to 18 years on January 1, 2007, who were continuously enrolled in the database through December 31, 2013, were included. Patients were assigned an HPV dose state (0, 1, 2, or 3) based on the last recorded dose...

Frontometaphyseal dysplasia (FMD) is caused by gain-of-function mutations in the X-linked gene FLNA in approximately 50% of patients. Recently we characterized an autosomal dominant form of FMD (AD-FMD) caused by mutations in MAP3K7, which accounts for the condition in the majority of patients who lack a FLNA mutation. We previously also described a patient with a de novo variant in TAB2, which we hypothesized was causative of another form of AD-FMD. In this study, a cohort of 20 individuals with AD-FMD is clinically evaluated...

OBJECTIVE: Radical trachelectomy is a valid alternative for the treatment of early-stage cervical cancer in young women who wish to preserve fertility potential. Recent data indicate that even less radical surgery could be performed in low-risk cases. The objective of our study was to evaluate the safety of simple vaginal trachelectomy and node assessment in patients with low-risk, early-stage cervical cancer (<2 cm). METHODS: From May 2007 to July 2016, 35 women underwent a simple vaginal trachelectomy with laparoscopic sentinel lymph node mapping + pelvic node dissection...

BACKGROUND: Fibromuscular dysplasia (FMD) is a systemic, nonatherosclerotic, noninflammatory vasculopathy that is often overlooked by clinicians. Clinical clues could help in selecting patients for further evaluation for the presence of FMD. Recently, it was observed that tortuosity of the coronary arteries is often present in patients with FMD-related abnormalities of the coronary artery. Therefore, we wondered if the presence of coronary tortuosity might provide a clinical clue to the diagnosis of extracoronary FMD...
