Endometriosis in Adolescents

Background and Objectives:

Women with endometriosis often report onset of symptoms during adolescence; however, the diagnosis of endometriosis is often delayed. The aim of this study was to describe the experience of adolescents who underwent laparoscopy for pelvic pain and were diagnosed with endometriosis: specifically, the symptoms, time from onset of symptoms to correct diagnosis, number and type of medical professionals seen, diagnosis, treatment, and postoperative outcomes.

Methods:

We reviewed a series of 25 females ≤21 years of age with endometriosis diagnosed during laparoscopy for pelvic pain over an 8-year period. These patients were followed up for 1 year after surgery.

Results:

The mean age at the time of surgery was 17.2 (2.4) years (range, 10–21). The most common complaints were dysmenorrhea (64%), menorrhagia (44%), abnormal/irregular uterine bleeding (60%), ≥1 gastrointestinal symptoms (56%), and ≥1 genitourinary symptoms (52%). The mean time from the onset of symptoms until diagnosis was 22.8 (31.0) months (range, 1–132). The median number of physicians who evaluated their pain was 3 (2.3) (range, 1–12). The adolescents had stage I (68%), stage II (20%), and stage III (12%) disease. Atypical endometriosis lesions were most commonly observed during laparoscopy. At 1 year, 64% reported resolved pain, 16% improved pain, 12% continued pain, and 8% recurrent pain.

Conclusions:

Timely referral to a gynecologist experienced with laparoscopic diagnosis and treatment of endometriosis is critical to expedite care for adolescents with pelvic pain. Once the disease is diagnosed and treated, these patients have favorable outcomes with hormonal and nonhormonal therapy.     

Immediate antiviral therapy appears to restrict resting CD4+ cell HIV-1 infection without accelerating the decay of latent infection

HIV type 1 (HIV-1) persists within resting CD4(+) T cells despite antiretroviral therapy (ART). To better understand the kinetics by which resting cell infection (RCI) is established, we developed a mathematical model that accurately predicts (r = 0.65, P = 2.5 × 10(-4)) the initial frequency of RCI measured about 1 year postinfection, based on the time of ART initiation and the dynamic changes in viremia and CD4(+) T cells. In the largest cohort of patients treated during acute seronegative HIV infection (AHI) in whom RCI has been stringently quantified, we found that early ART reduced the generation of latently infected cells. Although RCI declined after the first year of ART in most acutely infected patients, there was a striking absence of decline when initial RCI frequency was less than 0.5 per million. Notably, low-level viremia was observed more frequently as RCI increased. Together these observations suggest that (i) the degree of RCI is directly related to the availability of CD4(+) T cells susceptible to HIV, whether viremia is controlled by the immune response and/or ART; and (ii) that two pools of infected resting CD4(+) T cells exist, namely, less stable cells, observable in patients in whom viremia is not well controlled in early infection, and extremely stable cells that are established despite early ART. These findings reinforce and extend the concept that new approaches will be needed to eradicate HIV infection, and, in particular, highlight the need to target the extremely small but universal, long-lived latent reservoir.     

Histamine regulation of pancreatitis and pancreatic cancer: a review of recent findings

The pancreas is a dynamic organ that performs a multitude of functions within the body. Diseases that target the pancreas, like pancreatitis and pancreatic cancer, are devastating and often fatal to the suffering patient. Histamine and histamine receptors (H1-H4HRs) have been found to play a critical role in biliary diseases. Accordingly, the biliary tract and the pancreas share similarities with regards to morphological, phenotypical and functional features and disease progression, studies related the role of H1-H4HRs in pancreatic diseases are important. In this review, we have highlighted the role that histamine, histidine decarboxylase (HDC), histamine receptors and mast cells (the main source of histamine in the body) play during both pancreatitis and pancreatic cancer. The objective of the review is to demonstrate that histamine and histamine signaling may be a potential therapeutic avenue towards treatment strategies for pancreatic diseases.Key Words: Histamine, pancreas, pancreatitis, pancreatic cancer
