Human kallikrein-related peptidase 12 (KLK12) splice variants expression in breast cancer and their clinical impact
Kallikrein-related peptidases (KLKs) are a group of 15 serine proteases,
hormonally regulated, and localized on chromosome 19q13.4. Alternative
splicing is a process that plays significant role in the development,
physiology, and different diseases, like cancer. Kallikrein family
numbers more than 82 alternative transcripts. Understanding the role
that those gene transcripts play in various cancer types, could lead to
the discovery of diagnostic markers or drug targets. The present study
was designed to analyze the expression profile of the splice variants of
kallikrein-related peptidase 12 (KLK12) in breast cancer patients and to
evaluate their clinical significance. KLK12 splice variants (KLK12sv3
and KLK12sv1/KLK12sv2) were examined in 69 tissue samples of breast
cancer using quantitative real-time PCR as well as semi-quantitative
PCR. Relative quantitative expression of KLK12 was statistically
associated to clinicopathological parameters. From the splice variants
examined, statistical associations with clinicopathological parameters
were obtained only from KLK12sv3 variant. KLK12sv3 is more frequently
expressed in tumors of lower grade (p = 0.040), early patient TNM stage
(p = 0.024), and smaller tumor size (p = 0.023). Positive KLK12sv3
expression is associated with longer patient disease-free survival (DFS)
(p = 0.042) and higher progesterone receptor concentration (p = 0.008).
KLK12sv1/KLK12sv2 expression is statistically associated with KLK12sv3
expression (p = 0.001). KLK12sv3 can be regarded as a marker of good
prognosis in breast cancer
An extremely rare clinical manifestation of acute appendicitis in a nonagenarian patient: lessons still to be learned
Abstract Acute appendicitis is associated with a relatively high mortality rate among elderly patients due to the unusual clinical presentation that often leads to misdiagnosis and, in turn, severe complications. This report describes an extremely uncommon clinical manifestation of acute appendicitis in an elderly patient - a subcutaneous abdominal wall abscess initially treated as cellulitis. Despite the initial misdiagnosis, contrast-enhanced computed tomography revealed a circumscribed inflammatory process of the appendix that was in close proximity to the abdominal wall. The patient underwent a surgical drainage of the abscess, received broad-spectrum antibiotics, and was discharged on day 12 following an uneventful course. Diagnosis of acute appendicitis in elderly patients is challenging due to the atypical clinical presentation and co-existing comorbidities that can be misleading. Early application of high-resolution imaging techniques is necessary to identify the cause of acute abdomen in the elderly population
Rupture of a mature cystic teratoma in a young girl caused by a car accident: an extremely rare case and review of the literature
Mature cystic teratomas (MCT) of the ovary or dermoid cysts are commonly encountered benign ovarian lesions accounting for approximately 70% of benign tumors and originating from germ cells. A rare case of peritonitis in a 17-year-old female patient caused by traumatic rupture of an MCT of the right ovary is herein presented. A meticulous search of the literature has also been performed. Due to deterioration of patient’s clinical condition, she was urgently led to surgery and intraoperative investigation of the peritoneal cavity revealed an inflamed ruptured ovarian cyst along with extensive peritoneal adhesions and purulent peritoneal fluid. A cyst resec-tion was performed with preservation of the ovary followed by adhesiolysis and meticulous abdominal washing and the patient had an uneventful recovery. Despite its rarity, traumatic rupture of ovarian cyst should be considered at evaluation of trauma patients with special attention to cases with a discovered or known presence of ovarian cyst
