Pelvic inflammatory disease in the adolescent and young adult: An update.

Pelvic inflammatory disease (PID) is an infection of the female upper genital tract that is typically polymicrobial with classic core involvement of Neisseria gonorrhoeae and/or Chlamydia trachomatis, though other endogenous flora from the vagino-cervical areas can be involved as well. It is often a sexually transmitted disease but other etiologic routes are also noted. A variety of risk factors have been identified including adolescence, young adulthood, adolescent cervical ectropion, multiple sexual partners, immature immune system, history of previous PID, risky contraceptive practices and others. An early diagnosis and prompt treatment are necessary to reduce risks of PID complications such as chronic pelvic pain, ectopic pregnancy and infertility. Current management principles of PID are also reviewed. It is important for clinicians to screen sexually active females for common sexually transmitted infections such as Chlamydia trachomatis and provide safer sex education to their adolescent and young adult patients. Clinicians should provide comprehensive management to persons with PID and utilize established guidelines such as those from the US Centers for Disease Control and Prevention (CDC).

Síndrome de Fitz-Hugh-Curtis: una causa de dolor en hipocondrio derecho / Fitz-Hugh-Curtis syndrome: A cause of right upper quadrant abdominal pain

El síndrome de Fitz-Hugh-Curtis, también conocido como perihepatitis, es una complicación poco frecuente de la enfermedad pélvica inflamatoria con una incidencia variable en función de los criterios diagnósticos utilizados. Este síndrome consiste en una inflamación de la cápsula hepática y el peritoneo adyacente sin compromiso del parénquima hepático como resultado de una infección directa por una diseminación intraperitoneal desde una infección pélvica. Sus manifestaciones clínicas son inespecíficas e incluyen dolor y molestias en el hipocondrio derecho de rápida evolución, confundiéndose con frecuencia con otras enfermedades hepatobiliares, del tubo digestivo o renales. En los últimos años la tomografía computarizada multidetector se ha revelado como un procedimiento muy útil y no invasivo, ofreciendo imágenes altamente indicativas de diagnóstico, en el contexto clínico adecuado. Debe considerarse la posibilidad de este síndrome, ya que un error diagnóstico puede ocasionar intervenciones quirúrgicas innecesarias

Fitz-Hugh-Curtis syndrome (FHCS), also known as perihepatitis, is a rare complication of pelvic inflammatory disease. It has a different incidence depending on which diagnostic criteria are used. FHCS consists of inflammation of the hepatic capsule and surrounding peritoneum, without involvement of the hepatic parenchyma, due to intraperitoneal dissemination from a pelvic infection. Clinical manifestations are nonspecific and include a sudden onset of pain and discomfort in the right hypochondrium, commonly confused with other hepatobiliary, gastrointestinal or renal diseases. In recent years, Multidetector Computed Tomography has proven to be a very useful and non-invasive tool, which offers diagnostic confidence within the appropriate clinical setting. Radiological diagnosis of FHCS can avoid unnecessary surgical procedures

Ozone therapy ameliorates inflammation and endometrial injury in rats with pelvic inflammatory disease.

As a common cause of infertility, pelvic inflammatory disease (PID) is characterized by chronic pain, ectopic pregnancy as well as inflammation and infection of the female upper genital tract. Ozone water, also known as O3, has been previously reported to be a distinctly effective agent in treating inflammation. During the present study, we asserted the hypothesis that O3 could be applied by pelvic inflammation and works to regulate the expression of inflammatory factors including interleukin-6 (IL-6), IL-2 and tumor necrosis factor-α (TNF-α). In an attempt to evaluate the effect of O3 on PID, an acute PID rat model was subsequently established. O3 at concentrations of 45 µg/mL and 60 µg/mL in addition to levofloxacin (LVLX) was injected respectively into the PID rats in a bid to alter the contents of inflammatory factors and immunologic markers. Hematoxylin-eosin (HE) staining was applied to analyze endometrial inflammation. Reductions to the contents of IL-6 and TNF-α were recorded, while that of IL-2, IgA, IgG, IgM, C3 and C4, and E rosette formation rate and transformation rate of T lymphocytes exhibited notably elevated levels after the PID rats had been injected with 45 µg/mL O3, 60 µg/mL O3 or LVLX. The pathological condition of the endometrium in rats with PID was alleviated among the PID rats after injected with the 45 µg/mL O3, 60 µg/mL O3 or LVLX. Taken together, the key findings of the current study present evidence demonstrating that the administration of O3 to the pelvic cavity ameliorated the PID conditions among rat models via inhibition of the necrosis of the endometrial epithelial cells as well as alleviated the inflammatory reactions, highlighting a potential novel PID treatment target.

The obesogen tributyltin induces abnormal ovarian adipogenesis in adult female rats.

Tributyltin chloride (TBT) is an obesogen associated with various metabolic and reproductive dysfunctions after in utero exposure. However, few studies have evaluated TBT's obesogenic effect on adult ovaries. In this study, we assessed whether TBT's obesogenic effects resulted in adult ovarian adipogenesis and other reproductive abnormalities. TBT was administered to adult female Wistar rats, and their reproductive tract morphophysiology was assessed. We further assessed the ovarian mRNA/protein expression of genes that regulate adipogenesis. Rats exposed to TBT displayed abnormal estrous cyclicity, ovarian sex hormone levels, ovarian follicular development and ovarian steroidogenic enzyme regulation. Rats exposed to TBT also demonstrated abnormal ovarian adipogenesis with increased cholesterol levels, lipid accumulation, and PPARγ, C/EBP-ß and Lipin-1 expression. A negative correlation between the ovarian PPARγ expression and aromatase expression was observed in the TBT rats. Furthermore, TBT exposure resulted in reproductive tract atrophy, inflammation, oxidative stress and fibrosis. Ovarian dysfunctions also co-occurred with the uterine irregularities. Abnormal ovarian adipogenic markers occurring after TBT exposure may be associated with uterine irregularities. A positive correlation between the ovarian cholesterol levels and uterine inflammation was observed in the TBT rats. These findings suggest that TBT leads to ovarian obesogenic effects directly by abnormal adipogenesis and/or indirectly through adult reproductive tract irregularities.

Elderly Fitz-Hugh-Curtis syndrome observed with superb microvascular imaging system.

Fitz-Hugh-Curtis syndrome (FHCS) is defined as inflammation on the surface of the liver following sexually transmitted chlamydia infection. We successfully observed the microvascular structure of the inflamed portion between the abdominal wall and surface of the liver in an elderly patient with FHCS using a superb microvascular imaging (SMI) system, a new technology developed for observing minute vascular flow. An 80-year-old Japanese female with right dorsal to lateral abdominal pain and fever came to our hospital. Anti-chlamydia antibodies were positive. SMI revealed signals suggesting small vessels passing from the liver surface to the hypoechoic space.

Behavioral changes before metritis diagnosis in dairy cows.

Metritis is common in the days after calving and can reduce milk production and reproductive performance. The aim of this study was to identify changes in feeding and social behavior at the feed bunk, as well as changes in lying behavior before metritis diagnosis. Initially healthy Holstein cows were followed from 3 wk before to 3 wk after calving. Behaviors at the feed bunk were recorded using an electronic feeding system. Lying behavior was recorded using data loggers. Metritis, based upon the characteristics of vaginal discharge at d 3, 6, 9, 12 and 15 after calving, was diagnosed in 74 otherwise healthy cows. Behavior of these cows, beginning 2 wk before calving until the day of diagnosis, was compared with 98 healthy cows (never diagnosed with any health disorder, including ketosis, mastitis, and lameness) during the transition period. During the 2 wk before calving, cows later diagnosed with metritis had reduced lying time and fewer lying bouts compared with healthy cows. In the 3 d before clinical diagnosis, cows that developed metritis ate less, consumed fewer meals, were replaced more often at the feed bunk, and had fewer lying bouts of longer duration compared with healthy cows. We concluded that changes in feeding as well as social and lying behavior could contribute to identification of cows at risk of metritis.

Changes in feeding, social, and lying behaviors in dairy cows with metritis following treatment with a nonsteroidal anti-inflammatory drug as adjunctive treatment to an antimicrobial.

Dairy cows with metritis display sickness behaviors, and nonsteroidal anti-inflammatory drugs (NSAID) have the potential to reduce these responses. The objective of this study was to investigate changes in feeding, social, and lying behaviors in dairy cows with metritis that had been treated with the NSAID meloxicam. After parturition, cows were housed in a dynamic, mixed-parity group of 20 animals with access to 12 electronic feed bins, 2 electronic water bins, and 24 lying stalls in a freestall pen. Every third day after parturition, vaginal discharge was evaluated to diagnose metritis based on the presence of foul smell and characteristic visual appearance. When diagnosed with metritis, animals (n = 87) were randomly allocated to receive either a single dose of meloxicam (0.5 mg/kg of body weight subcutaneously) or a placebo solution. All metritic animals received an antimicrobial (ceftiofur) for 5 d. We measured feeding and social behaviors at the feed bunk, as well as lying behaviors, and assessed within-cow changes from the day before to the day of (d 0) NSAID treatment, and from the day before to d 1 to 5 after treatment. Generally, behaviors changed around the day of diagnosis of metritis. Compared with the placebo group, cows that received meloxicam had a greater increase in the number of visits to the feeder, but tended to show less of an increase in dry matter intake and feeding time. These differences did not persist beyond 24 h after NSAID treatment. We observed no differences in changes in number of meals and feeding rate on d 0, but from d 1 to 5 cows treated with meloxicam had a lesser decrease in the number of meals and tended to have a greater decrease in feeding rate than did placebo-treated cows. In multiparous cows on d 0 and from d 1 to 5, meloxicam treatment was associated with decreased lying times. In primiparous cows, lying time changes were similar between treatments on d 0, but lying times increased more on d 1 to 5 for meloxicam than for placebo cows. Overall, cows changed the number of lying bouts on d 0, and this increase tended to be smaller for the meloxicam cows. There were no treatment differences in changes of social behavior. In summary, we observed inconsistent and generally small effects of a single dose of meloxicam in addition to antimicrobial therapy on the behavior of cows with metritis.

Clinical characteristics of genital chlamydia infection in pelvic inflammatory disease.

BACKGROUND: Chlamydia infection in acute pelvic inflammatory disease (PID) is associated with serious complications including ectopic pregnancy, tubal infertility, Fitz-Hugh-Curtis syndrome and tubo-ovarian abscess (TOA). This study compared clinical and laboratory data between PID with and without chlamydia infection. METHODS: The medical records of 497 women who were admitted with PID between 2002 and 2011 were reviewed. The patients were divided into two groups (PID with and without chlamydia infection), which were compared in terms of the patients' characteristics, clinical presentation, and laboratory findings, including inflammatory markers. RESULTS: The chlamydia and non-chlamydia groups comprised 175 and 322 women, respectively. The patients in the chlamydia group were younger and had a higher rate of TOA, a longer mean hospital stay, and had undergone more surgeries than the patients in the non- chlamydia group. The erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and CA-125 level were higher in the chlamydia group than in the non-chlamydia group, but there was no significant difference in the white blood cell count between the two groups. The CA-125 level was the strongest predictor of chlamydia infection, followed by the ESR and CRP level. The area under the receiving operating curve for CA-125, ESR, and CRP was 0.804, 0.755, and 0.663, respectively. CONCLUSIONS: Chlamydia infection in acute PID is associated with increased level of inflammatory markers, such as CA-125, ESR and CRP, incidence of TOA, operation risk, and longer hospitalization.

MDCT of pelvic inflammatory disease: a review of the pathophysiology, gamut of imaging findings, and treatment.

Representing an ascending, sexually spread pyogenic infection of the female genital tract, pelvic inflammatory disease (PID) is a commonly encountered cause for emergency visits and hospitalizations among young and adult female patients. Though gynecologic evaluation and sonography constitute the mainstay of diagnosis, multidetector CT imaging of the abdomen and pelvis is not uncommonly performed, often as the initial imaging modality, due to the frequently vague and indeterminate clinical presentation. As such, knowledge and attenuation to the often subtle early imaging features of PID afford the radiologist a critical chance to direct and expedite appropriate pathways of patient care, minimizing the risk for secondary complications, including infertility, ectopic pregnancy, and enteric adhesions. In this paper, we will review the pathophysiology, clinical presentation, early and late imaging features of PID as well as potential secondary complications and treatment options. Additionally, we will discuss published data metrics on CT performance regarding sensitivity and specificity for diagnosis as well as potential imaging differential diagnostic considerations.

Is Pelvic Inflammatory Disease a Risk Factor for Ovarian Cancer?

BACKGROUND: Pelvic inflammatory disease (PID) has been proposed as a risk factor for ovarian cancer. However, the existing literature on the association between PID and ovarian cancer risk is inconclusive, and only few cohort studies have been conducted. METHODS: Using nationwide Danish registries, we conducted a population-based cohort study including all women from the birth cohorts 1940 to 1970 in Denmark during 1978-2012 (n = 1,318,929) to investigate the association between PID and subsequent risk of epithelial ovarian cancer. Among women in the cohort, 81,281 women were diagnosed with PID and 5,356 women developed ovarian cancer during follow-up through 2012. Cox regression models were used to estimate HRs and 95% confidence intervals (CI) for the association between PID and ovarian cancer, both overall and according to histotype. RESULTS: For ovarian cancer overall, we observed no association with PID (HR, 1.05; 95% CI, 0.92-1.20). However, in histotype-specific analyses, we found a statistically significantly increased risk of serous ovarian cancer among women with PID (HR, 1.19; 1.00-1.41; P = 0.047). Conversely, PID was not convincingly associated with risk of any of the other histotypes of ovarian cancer. CONCLUSIONS: PID was associated with a modestly increased risk of serous ovarian cancer, but not other histotypes. IMPACT: Our results indicate that PID is not a strong risk factor for ovarian cancer. Whether PID is slightly associated with risk of serous ovarian cancer has to be confirmed in other studies.

Chronic Pelvic Inflammation Diminished Ovarian Reserve as Indicated by Serum Anti Mülerrian Hormone.

OBJECTIVE: To explore the potential damaging effect of chronic pelvic inflammation on ovarian reserve. DESIGN: Case-control study. PATIENTS: A total of 122 women with bilateral tubal occlusion, diagnosed by hysterosalipingography (HSG) and 217 women with normal fallopians were recruited. MEASUREMENTS: Serum anti-Mullerian hormone (AMH), basic follicle-stimulating hormone (FSH), luteining hormone (LH), estradiol (E2), and testosterone (T) were measured; and antral follicle counts (AFCs) were recorded. RESULTS: Significantly lower level of AMH was observed in women with bilateral tubal occlusion compared to control group [2.62 (2.95) ng/ml vs. 3.37 (3.11) ng/ml, P = 0.03], and the difference remained after adjustment of BMI (Padjust = 0.04). However, no statistical difference was found in the levels of FSH [7.00 (2.16) IU/L vs. 6.74 (2.30) IU/L], LH [4.18 (1.52) IU/L vs. 4.63 (2.52) IU/L], E2 [35.95 (20.40) pg/ml vs. 34.90 (17.85) pg/ml], T [25.07±11.46 ng/dl vs. 24.84±12.75 ng/dl], and AFC [6.00 (4.00) vs. 7.00 (4.00)] between two groups (p>0.05). CONCLUSIONS: Women with bilateral tubal occlusion showed decreased AMH level, suggesting that chronic pelvic inflammation may diminish ovarian reserve. More caution should be paid when evaluating the detriment of PID on female fertility.

A novel marker for the assessment of the treatment result in pelvic inflammatory disease.

BACKGROUND: Although various laboratory tests have been studied with an intended use in the diagnosis of pelvic inflammatory disease (PID) and the assessment of treatment response, the neutrophil/lymphocyte ratio (NLR) has not been investigated in PID. We aimed to explore the value of blood NLR in diagnosis of PID and assessment of the treatment response. METHODS: Sixty-five patients followed-up and treated with the diagnosis of PID in Izmir Tepecik Training and Research Hospital were retrospectively reviewed. The NLR measured before treatment and after clinical remission in the patients diagnosed with PID were assessed and compared with controls (N.=65). RESULTS: In the patient group, the NLR measured before treatment was statistically significantly higher than the NLR measured after clinical remission (6.9±6.4 vs. 2.03±0.8, P<0.001). Similarly, comparison of the NLR measured in the patient group before treatment with the control group showed that this ratio was statistically significantly higher in the patient group before treatment (6.9±6.4 vs. 1.9±0.5, P<0.001). A comparison of the NLR measured after clinical remission did not reveal a statistically significant difference when compared with control group (1.9±0.5 vs. 2.03±0.8, P=0.981). CONCLUSIONS: The NLR increases in patients diagnosed with PID and returns to normal levels when the patients enter clinical remission. Since there is currently no laboratory test available that indicates clinical improvement by returning to normal levels, as achieved by the NLR, and since it is an inexpensive and easy-to-apply test, we suggest that the NLR can be conveniently used to show clinical improvement in PID.

Pelvic inflammatory disease: diagnosis and treatment in the emergency department [digest].

Pelvic inflammatory disease is a common disease that is associated with significant complications including infertility, chronic pelvic pain, ruptured tubo-ovarian abscess, and ectopic pregnancy. The diagnosis may be delayed when the presentation has nonspecific signs and symptoms. Even when it is properly identified, pelvic inflammatory disease is often treated suboptimally. This review provides evidence-based recommendations for the diagnosis, treatment, disposition, and follow-up of patients with pelvic inflammatory disease. Arranging follow-up of patients within 48 to 72 hours and providing clear patient education are fundamental to ensuring good patient outcomes. Emerging issues, including new pathogens and evolving resistance patterns among pelvic inflammatory disease pathogens are reviewed. [Points & Pearls is a digest of Emergency Medicine Practice].

Smoking, poor nutrition, and sexually transmitted infections associated with pelvic inflammatory disease in remote North Queensland Indigenous communities, 1998-2005.

BACKGROUND: Indigenous women in remote North Queensland have a high prevalence of unhealthy lifestyle behaviors and associated health conditions such as sexual transmitted infections (STI). The association of severe pelvic inflammatory disease (PID) with these factors has not been studied. The purpose of this study is to associate the factors with severe PID, as indicated by hospitalization in a high risk population in North Queensland Indigenous communities. METHODS: A cross-sectional association of 1445 Indigenous women using linked hospital separation and survey data during 1998-2005. RESULTS: The mean age of participating women was 37.4 years, 60% were of Aboriginal and 40% were Torres Strait Island (TSI) people. More than half of them (52.5%) were smokers, 9.3% had chlamydia and 2.6% had gonorrhoea with the overall prevalence of STI among those less than 25 years of age being 23.9%. Among the 47 participants diagnosed with PID in the study period, 42.5% were under 25 years and 95.7% (45 cases) were under 55 years (OR 2.5, 95% CI 1.2-4.1 among women younger than 25 compared to those 25 years and over). PID was strongly associated with smoking (OR 3.1, 95% CI 1.4-9.2) independent of age, ethnicity, STI and folate status. Low red cell folate increased PID hospitalization by 4 times (95% CI 1.5-13.2 of lowest quartile compared to the highest quartile) regardless of age. Having a STI significantly increased the likelihood of severe PID by 2.2 times (95% CI: 1.03-4.5) in Indigenous women younger than 45 years, independent of smoking and folate level. The risk of PID hospitalization was higher for gonorrheal infections (OR 3.2, 955 CI 1.1-9.6) compared to chlamydial infections (OR 1.5 95% CI 0.7-3.5). CONCLUSIONS: Young Indigenous women in North Queensland communities are at very high risk for STI and PID. Smoking, low folate, and STI are clustered, and are associated with PID hospitalizations. Much of this can be prevented with improved nutrition and access to preventive services, especially tobacco control, regular STI screening and treatment, as well as more investment in sexual health education and awareness.

The sensitivity and specificity of transvaginal ultrasound with regard to acute pelvic inflammatory disease: a review of the literature.

PURPOSE: This review aims to sum up current knowledge on the sensitivity and specificity of ultrasound features suggestive of acute pelvic inflammatory disease (PID). METHODS: A PubMed database search was undertaken, using the MeSH terms "(pelvic inflammatory disease or salpingitis or adnexitis) and ultrasonography". We included original articles evaluating the performance of vaginal ultrasound in detecting acute PID. RESULTS: Seven articles were selected, including between 18 and 77 patients each. The golden standard used was laparoscopy/endometrial biopsy in six studies and mostly clinical evaluation in one. "Thick tubal walls" proved to be a specific and sensitive ultrasound sign of acute PID, provided that the walls of the tubes can be evaluated, i.e., when fluid is present in the tubal lumen (100 % sensitivity). The cogwheel sign is also a specific sign of PID (95-99 % specificity), but it seems to be less sensitive (0-86 % sensitivity). Bilateral adnexal masses appearing either as small solid masses or as cystic masses with thick walls and possibly manifesting the cogwheel sign also seems to be a reasonably reliable sign (82 % sensitivity, 83 %specificity). Doppler results overlap too much between women with and without acute PID for them to be useful in the diagnosis of acute PID, even though acutely inflamed tubes are richly vascularized at color Doppler. CONCLUSIONS: Even though the results of our review suggest that transvaginal ultrasound has limited ability to diagnose acute PID, it is likely to be helpful when managing women with symptoms of acute PID, because in some cases the typical ultrasound signs of acute PID can be detected.

Unusual ectopic pregnancies: a retrospective analysis of 65 cases.

AIM: The aim of this study was to retrospectively investigate unusual ectopic pregnancies (EP) and compare them with fallopian ones. MATERIAL AND METHODS: A total of 1000 cases of ectopic pregnancies were analyzed, including 65 unusual cases. We discussed distribution, incidence, risk factors, examinations, treatments and prognoses. RESULTS: Ovarian pregnancy was associated with placement of intrauterine device and pelvic inflammatory diseases. Extratubal EP have a high rate of misdiagnosis and presented more serious manifestations. Some unusual EP could be diagnosed by ultrasonography. Ovarian pregnancy was usually manifested as positive culdocentesis. Most of the unusual EP underwent surgery, except some early cervical and corneal pregnancies. CONCLUSION: Although extratubal pregnancies are difficult to diagnose, some histories and auxiliary examinations could make diagnosis easier for clinical physicians. Surgery is still the most effective approach for treatment of unusual EP, while conservative treatment of mifepristone combined with methotrexate or curettage could be used for early diagnosis and treatment of cervical pregnancy.

Global survey of healthcare practitioners' beliefs and practices around intrauterine contraceptive method use in nulliparous women.

BACKGROUND: Despite the efficacy and safety of intrauterine contraceptive methods (IUCs), healthcare providers (HCPs) are sometimes reluctant to recommend their use, particularly in nulliparous women. This study sought to understand the global practitioner perceived impediments to IUC provision. STUDY DESIGN: We developed an online survey for HCPs administered across 4 regions comprising 15 countries. We sought their attitudes to IUC provision; their perceived barriers to IUC use, particularly in nulliparous women; as well as their knowledge of the World Health Organization Medical Eligibility Criteria (WHO MEC) for contraceptive use. RESULTS: We received 1862 responses from HCPs in 15 countries grouped into 4 regions, with an average country response rate of 18%. For analysis, the results were grouped into these regions: Latin America, 402 (21.6%); USA, 156 (8.4%); Europe and Canada, 1103 (59.2%); and Australia, 201 (10.8%). The two most frequently identified perceived barriers to IUC use in nulliparous women were difficulty of insertion (56.6%) and pelvic inflammatory disease (PID) (49.2%), but responses differed by region and HCP type. Only 49.7% recognized the correct WHO MEC category for IUC use in nulliparous women. DISCUSSION: The results of this survey confirm that, across the four regions, the two main barriers to IUC provision for nulliparous women are concern about the difficulty of insertion and PID. Providers' knowledge of the WHO MEC was lacking universally. A global effort is required to improve understanding of the evidence and knowledge of available guidelines for IUC use.
