The Influence of Psychological Stress on HPV Infection Manifestations and Carcinogenesis.

Psychological stress is an important factor involved in disease manifestations of human papillomavirus (HPV) infection, and it can participate in HPV-associated carcinogenesis. The impact or effect which stress can have (exert) depends on a person's genetic pool, experiences and behaviors. Due to inconsistencies in some study results, this issue remains a subject of research. Concerning the course of HPV manifestations, it has been observed that a higher number of life stressors in at least the previous 6 months, the absence of social support and the types of personal coping mechanisms employed, all influence HPV progression. In women with cervical dysplasia, a connection between greater stress experiences and dysregulation of specific immune responses has been observed. Once HPV enters a cell via the α6 integrin there are three possible sequences: latent infection, subclinical infection, and clinically manifest disease. HPV proliferation in differentiated epithelial cells induces morphologically cytopathic changes (koilocytosis, epidermal thickening, hyperplasia, hyperkeratosis). Oncogenic transformation requires the integration of the virus genome into the host genome. In doing so, DNA in the E1 region of E2 breaks down, leading to transcription disorders of E6 and E7. For the formation of irreversible malignancy, the following sequence is necessary: initial expression of E6 and E7 genes followed by suppression of apoptosis and the stabile expression of E6 and E7 proteins that protect transformed cells from apoptosis. A successful immune response is characterized by a strong, local cell-mediated immune response. Several factors are important for the regression of HPV manifestation/infection, among which is psychological stress which can prolong the duration and severity of HPV disease. Stress hormones may reactivate latent tumor viruses, stimulate viral oncogene expression, and inhibit antiviral host responses. In the regression of HPV infection, increased activity of Th1 cells was observed. However, during psychosocial stress, a decrease in the Th1 type of immune response is seen, and there is a shift towards a Th2 response. Understanding perceived stress and biological changes in stress, as well as the evaluation of immune parameters, gives researchers a better picture of how stress influences HPV infections and how to improve disease management and outcomes.

Auricular acupuncture as effective pain relief after episiotomy: a randomized controlled pilot study.

PURPOSE: Previously, pain treatment following episiotomy has relied on non-steroid anti-inflammatory drugs as analgesics, whose use during breastfeeding remains controversial due of their transfer to the child. METHODS: This was a pilot randomized parallel single-center study aiming to evaluate the effects of auricular acupuncture on pain relief after episiotomy. The primary outcome was reduction of pain intensity using visual analogue scale (VAS) scores during the first three postpartum days. The patients were allocated to either of the groups by using a heads-tails binary result coin toss method and the allocation was not masked. The study was completed after including 60 healthy women that underwent mediolateral episiotomy performed during vaginal delivery, with 29 receiving acupuncture therapy and 31 not receiving acupuncture therapy for pain relief. Oral analgesic therapy was made available per request for all patients. RESULTS: This study showed that subjective experience of pain was significantly reduced in the acupuncture group on the second and third postpartum days (P = 0.004, P = 0.005, P = 0.22). There were no adverse effects of acupuncture noted. CONCLUSIONS: Our findings confirm that auricular acupuncture therapy may be a valuable adjunct to analgesic therapy in patients undergoing episiotomy during vaginal delivery. The results prompt a question whether our current 'best practice' may yet be improved.

Third Stage of Labor and Acupuncture.

Background: Acupuncture use in obstetrics has been increasing in Western medicine, especially to alleviate complications of pregnancy, the most important cause of maternal mortality worldwide. One quarter of maternal deaths are caused by complications in the third stage of labor, an interval between complete delivery of the baby and the complete expulsion of the placenta. Methods: This review analyzes the increased acupuncture use for pregnancy complications as a potential method of reducting maternal mortality during the third stage of labor. This overview focuses on acupuncture points and techniques to manage the third stage of labor and help patients with retained placentas. Passive (or expectant) management of the third stage of labor is occasionally associated with massive obstetric hemorrhage, a major cause of maternal morbidity and mortality, especially in low-income countries. Conclusions: Active management of the third stage of labor has been shown to reduce the risk of postpartum hemorrhage. Use of acupuncture in the first and second stages of labor could lead to a faster separation of the placenta in the third stage of labor. The possible effects of acupuncture in cases of retained placentas may have significant implications for possible complications and final outcomes of labor. Further studies are needed for more conclusive results.

Acupuncture for retained placenta: a retrospective case series.

BACKGROUND: A placenta is considered to be retained when it remains undelivered 30 or 60 min after the birth of the baby following active or physiological management of the third stage of labour, respectively. It can be life threatening for the mother. METHODS: We retrospectively examined the influence of acupuncture on the delivery of retained placentas in the third stage of labour in 70 women. In all cases the third stage of labour was actively managed, and acupuncture was provided 30 min after delivery at points KI16 and SP6 for 15 min. RESULTS: After acupuncture 77% of placentas separated successfully. In 10% of cases some retained placental tissue was detected and manual removal of the avulsed cotyledon was performed, while in 13% the entire placenta was retained and manual removal of the placenta under general anaesthesia was necessary. CONCLUSIONS: Acupuncture may help to facilitate placental separation but further controlled trials are needed.
