Giant cell tumors of bone (GCTBs) are characterized by mononuclear stromal cells and osteoclast-like giant cells; up to 95% have H3F3A gene mutation. The RANKL inhibitor denosumab, when used for the treatment of GCTB, leads to histological changes such as new bone formation and giant cell depletion. Here we assessed the diagnostic utility of immunohistochemical staining with the antibodies against histone H3.3G34 W, G34R and G34 V mutant proteins for GCTB and other histologically similar bone and joint lesions...

Multiple myeloma is a hematological malignancy, which sometimes creates difficulties in diagnosis, based on the presence of monoclonal protein in serum/urine and plasmocyte infiltration in the bone marrow, and on the other hand, synchronous cancers are also a diagnostic challenge. We present a case report of a patient with concurrent breast cancer and multiple myeloma. A 68-year-old woman was admitted to the hospital with diagnosis of left breast cancer in first stage of the disease. In the past, she had had several episodes of thrombocytopenia, leucocytosis, and mild anaemia, which were followed by hematologist in outpatient setting...

Hemophagocytic lymphohistiocytosis (HLH) is a rare but severe and potentially fatal syndrome that can occur during pregnancy. A 36 years-old woman, at 29 weeks of gestation, presented with itchiness and jaundice since a week. On clinical examination she was apyrexial and frankly icteric. Laboratory data showed evidence of acute hepatitis. A complete work-up was made excluding viral hepatitis (HAV, HEV, HBV, HCV, HHV6, CMV, EBV) and autoimmune liver disease. Liver diseases related to pregnancy were not completely excluded...

The abnormal expression of tumor-associated proteases and lowered extracellular pH are important signatures strongly associated with cancer invasion, progression, and metastasis. However, their malignant effects were mainly identified using cell and tissue studies. To non-invasively visualize the heterogeneous distribution of these abnormal indicators in vivo and further disclose their collective behaviors, a target-triggered fluorescent nanoprobe composed of a ratiometric pH-sensitive dye, a near infrared dye (Cy5...

Testicular cancer is the most common solid malignancy affecting males between the ages of 15 and 35. The symptomatology caused by this tumor varies according to the site of metastasis. We present the case of a 26-year-old male who arrived to the emergency department with hematemesis. He had no previous medical history. On arrival, we noted enlargement of the left scrotal sac. There was also a mass in the left scrotum which provoked displacement of the penis and right testis. The serum alpha-fetoprotein level was 17,090 ng/mL, lactate dehydrogenase was 1480 U/L, and human chorionic gonadotropin was 287...

BACKGROUND: Demographic, clinical, and morphological characteristics of cutaneous melanoma are unknown for the Colombian population. We aim to provide these characteristics as well as population-based incidence and survival data. METHODS: All patients with an invasive cutaneous melanoma diagnosed in the period 2000-2009 registered in the population-based cancer registry of the metropolitan area of Bucaramanga were included for analysis (n = 169). Age-standardized incidence rates were calculated and melanoma-specific and overall survival estimated with follow-up until June 9, 2016, using Kaplan-Meier methodology, stratifying for gender, anatomical localization, and type of affiliation to the social security system...

Universally accepted as the treatment of choice for children needing renal replacement therapy, kidney transplantation affords children the opportunity for an improved quality of life over dialysis therapy. Immunologic and surgical advances over the last 15 years have improved the pediatric patient and kidney graft survival. Unique to pediatrics, congenital genitourinary anomalies are the most common primary diseases leading to kidney failure, many with urological issues. Early urological evaluation for post-transplant bladder dysfunction and emphasis on immunization adherence are the mainstays of pediatric pretransplant and post-transplant evaluations...

Interventional radiologists are often called for emergent control of abnormal uterine bleeding. Bleeding, even heavy bleeding as a result of uterine fibroids is not a common emergent procedure; instead, pregnancy and pregnancy related conditions, trauma and malignancy associated with bleeding can be the source of many interventional radiology on call events or procedures. Postpartum hemorrhage (PPH) is the most common cause, and is defined as blood loss of 500mL after vaginal delivery or 1000mL after cesarean section...

Actinic keratosis, leukoplakia, carcinoma in situ, and superficially invasive carcinomas of the lower lip are caused mainly by the cumulative effects of exposure of the vermilion of the lower lip to ultraviolet radiation. Current treatments all have limitations: cryosurgery or electrosurgery is suitable to treat only focal lesions; topical chemotherapy, which is an option for diffuse actinic damage, yields unreliable results; and laser treatment fails to rejuvenate the vermilion. However, "lip shave", which involves full-thickness excision of the damaged vermilion and reconstruction with an advancement labial mucosal flap, will produce a fresh mucosal lining to the vermilion border...

BACKGROUND: There are very few options to treat multidrug-resistant bacterial infections in children. A major barrier is the duration and complexity of regulatory trials of new antibiotics. Extrapolation of safety data from adult trials could facilitate drug development for children. OBJECTIVE: We performed a systematic review on the safety of antibiotic clinical trials (CTs) in children (0-18 years) to evaluate the overall quality of safety trials conducted in children and to determine if age-specific adverse events (AEs) could be identified for specific antibiotic classes...

BACKGROUND: Both fully covered (FC) and partially covered (PC) self-expandable metal stents (SEMSs) are now commercially available for distal malignant biliary obstruction (MBO). While FCSEMS can be easily removed at the time of re-interventions, it is theoretically prone to migration. However, few comparative data between FC and PC SEMSs have been reported. AIMS: The aim of this study was to compare clinical outcomes of FCSEMS with those of PCSEMS. METHODS: This was a multicenter, prospective study of FCSEMS for unresectable distal MBO with a historical control of PCSEMS, which was previously reported as the WATCH study...
