HIV1-TAT interacting protein (TIP60) is a haploinsufficient tumor suppressor. However, the potential mechanisms endowing its tumor suppressor ability remain incompletely understood. It plays a vital role in virus-induced cancers where TIP60 down-regulates the expression of human papillomavirus (HPV) oncoprotein E6 which in turn destabilizes TIP60. This intrigued us to identify the role of TIP60, in the context of a viral infection, where it is targeted by oncoproteins. Through an array of molecular biology techniques such as Chromatin immunoprecipitation, expression analysis and mass spectrometry, we establish the hitherto unknown role of TIP60 in repressing the expression of the catalytic subunit of the human telomerase complex, TERT, a key driver for immortalization...

We report a case of a patient with esophageal tuberculosis, a very uncommon form of extrapulrhonar tuberculosis. Initially, because of constitutional symptomatology and radiological findings of mediastinal lymph node enlargement, lymphoma was considered. However, the endoscopic findings of ulcerative masses and a sinus tract revealed by esophagram were suspicious of tuberculous origin. Diagnosis was achieved after bacterial examination of smear samples from esophageal ulcers that revealed bacillus tuberculous and histological demonstration of caseating granulomas in cervical lymph nodes...

OBJECTIVE: In Japan, the human papillomavirus (HPV) vaccination rate has sharply fallen to nearly 0% due to sensational media reports of adverse events. Online anti-HPV-vaccination activists often warn readers of the vaccine's dangers. Here, we aimed to examine frequently appearing contents on pro- and anti-HPV vaccination websites. METHODS: We conducted online searches via two major search engines (Google Japan and Yahoo! Japan). Targeted websites were classified as "pro," "anti," or "neutral" according to their claims, with the author(s) classified as "health professionals," "mass media," or "laypersons...

BACKGROUND Not all patients with spinal cord compression due to cervical spondylotic myelopathy (CSM) have clinical symptoms and signs. The aim of this study was to investigate and compare the imaging findings in asymptomatic and symptomatic patients with CSM with mild to moderate cervical spinal cord compression. MATERIAL AND METHODS A retrospective clinical study included 68 patients. Group A (n=30) had no symptoms and signs; group B (n=38) had symptoms and signs of cervical myelopathy. The age, sex, body mass index (BMI), history of steroid treatment, duration of symptoms, number of spondylotic cervical segments, Torg ratio, range of motion (ROM), incidence of cervical segmental instability, overall curvature of the cervical spine, direction of spinal cord compression, and spinal cord magnetic resonance imaging (MRI) signal intensity were compared...

Biqi capsule is a well-known traditional Chinese medicine (TCM) formula that has been widely applied for the clinical treatment of such diseases as rheumatoid arthritis, scapulohumeral periarthritis, and cervical spondylopathy. However, there is concern regarding the toxicity of Biqi capsule due to its active ingredients, strychnine and brucine. To investigate the toxicokinetics of strychnine and brucine after the oral administration of Biqi capsule to rats, a sensitive and simple rapid-resolution liquid chromatography/tandem mass spectrometry (RRLC-MS/MS) method was developed to determine the levels of strychnine and brucine in rat plasma...

BACKGROUND A case report of urethral diverticulum complicating pregnancy is presented. The diagnosis and management are challenging because of the rare nature of this condition, the varied presentations and differential diagnoses, and the possibility of misdiagnosis. CASE REPORT A 25-year-old primigravida with scheduled induction of labor at 39 weeks gestation due to gestational diabetes mellitus presented for a routine antenatal appointment at 38 weeks and four days. On digital cervical examination, she was found to have a large semi-solid anterior vaginal mass, shown by trans-vaginal ultrasound to have a nearly solid appearance of a 5×7 cm mass with septation...

This case report describes a patient who presented with myelopathy secondary to a large retro-odontoid post traumatic cicatrix. The objective of this study was to discuss the clinical presentation, pathogenesis, imaging, and surgical management of pseudoarthrosis tissue mass associated with odontoid nonunion. Atlantoaxial subluxation (AAS) has been widely reported in patients with rheumatoid arthritis. AAS leads to repeated cycles of partial tear and repair of ligaments around the altantoaxial complex, resulting in the formation of periodontoid mass (pseudotumor)...

Even though cervical cancer is quite a prevalent disease in Ghana, there is hardly any study on this disease. This paper sought to explore the experiences of cervical cancer patients living with the disease with emphasis on their knowledge about the disease before and after the diagnosis. Qualitative data were collected through in-depth interviews with cervical cancer patients undergoing treatment in a specialised cancer treatment health facility in rural Ghana. Cervical cancer patients had inadequate knowledge about the disease, its symptoms, risk factors, treatment and prevention prior to being diagnosed of the disease...

Although the etiology of spontaneous spinal epidural hematoma (SSEH) is unclear, SSEH is known to be associated with anticoagulants, coagulopathy, vascular malformation, hypertension, and pregnancy. However, no report has been issued on the relation between SSEH and venous phlebolith. Here, the authors present an extremely rare case of SSEH associated with phlebolith in the cervical spine and suggest a possible pathogenesis. A 36-year-old man without any relevant medical history presented with neck pain and numbness and severe radiating pain on the left arm...

Metastasis to the female genital tract from extragenital primary cancer is uncommon. In this case, a 46-year-old woman was diagnosed with invasive lobular carcinoma of the left breast in 2011. She had left breast conserving surgery, chemotherapy, radiation, and hormonal therapy (gosereline and tamoxifen). However, she developed menorrhagia after interruption of hormonal therapy and incidentally, the ultrasonogram of her pelvis showed a solid, large mass in the cervix. It looked like leiomyoma. Because of massive vaginal bleeding requiring multiple blood transfusions, she underwent total hysterectomy with bilateral salpingo-oophorectomy...

Giant fibrovascular polyp of the esophagus is a descriptive diagnostic term intended to encompass rare, large, polypoid esophageal masses composed of fibroadipose tissue. Despite sometimes dramatic clinical presentations, they have historically been considered to represent reactive, non-neoplastic proliferations. Recently, however, a small number of reports have described well-differentiated liposarcomas of the esophagus, mimicking giant fibrovascular polyps. In order to clarify the relationship between esophageal liposarcoma and giant fibrovascular polyp, we retrieved esophageal cases coded as 'giant fibrovascular polyp,' 'lipoma' and 'liposarcoma' from our archives and re-examined their clinicopathologic features and MDM2 amplification status...

INTRODUCTION: Cervical cancer is the tenth most common cancer and the eighth most frequent cause of death among women in Singapore. Human papillomavirus (HPV) infection is the necessary cause of cervical cancer and therefore the risk of cervical cancer can be substantially reduced through vaccination. This study was conducted to evaluate the cost-effectiveness of two-dose HPV vaccination, as part of a national vaccination programme for 12-year-old girls in Singapore, from the perspective of the healthcare payer...
