RESUMO A doença inflamatória pélvica (DIP) é um processo inflamatório de natureza infecciosa que pode atingir estruturas e órgãos do trato genital superior. Devido à sua importância epidemiológica e de suas graves complicações, este artigo atualiza e propõe uma abord- agem sistemática da DIP. Os principais agentes etiológicos são a Neisseria gonorrhoeae, Chlamydia trachomatis e outros agentes etiológicos de uretrites, cervicites, vulvovaginites e vaginoses, em geral, polimicrobiana, o que é a base de sua terapêutica. A mulher deve ser investigada para DIP quando apresenta, especialmente, desconforto abdominal, dor lombar, dispareunia e nódoas ou manchas ao exame ginecológico, previamente a pro- cedimentos transcervicais.

  • Dyspareunia: an Integrated Approach to Assessment and Diagnosis
    PROBLEMS IN FAMILY PRACTICE Dyspareunia: An Integrated Approach to Assessment and Diagnosis Genell Sandberg, PhD, and Randal P. Quevillon, PhD Seattle, Washington, and Vermillion, South Dakota Dyspareunia, or painful intercourse, is frequently referred to as the most common female sexual dysfunction. It can occur singly or be manifested in combination with other psychosexual disorders. Diagnosis of dyspareunia is appropriate in cases in which the experience of pain is persistent and severe. There has been little agreement concerning the origin of dyspareunia. Or­ ganic conditions and psychological variables have alternately been pre­ sented as major factors in causality. There is a presumed high incidence of physical disease associated with dyspareunia when compared with other female sexual dysfunctions. In the majority of cases, however, organic fac­ tors are thought to be rare in contrast with sexual issues and interpersonal or intrapsychic difficulties as a cause of continuing problems. The finding of an organic basis for dyspareunia does not rule out emotional or psychogenic causes. Thorough and extensive gynecologic and psycholog­ ical evaluation is essential in cases of dyspareunia. The etiology of dys­ pareunia should be viewed on a continuum from primarily physical to primar­ ily psychological with many women falling in the middle area. recurrent pattern of genital pain during or im­ Dyspareunia and vaginismus are undeniably linked, A mediately after coitus is the basis for the diagnosis and repeated dyspareunia is likely to result in vaginis­ of dyspareunia.1 The Diagnostic and Statistical Man­ mus, as vaginismus may be the causative factor in ual of Mental Disorders (DSM-III)2 has included dys­ dyspareunia.6-7 The difference between vaginismus pareunia under the classification of psychosexual dis­ and dyspareunia is that intromission is generally pain­ orders.

ETIOLOGY Pelvic inflammatory disease (PID) is an infection of the upper genital tract that involves any combination of the uterus, endometrium, ovaries, fallopian tubes, pelvic peritoneum and adjacent tissues. PID consists of ascending infection from the lower-to-upper genital tract. Prompt diagnosis and treatment is essential to prevent long-term sequelae. Most cases of PID can be categorized as sexually transmitted and are associated with more than one organism or condition, including: Bacterial: Chlamydia trachomatis (CT) Neisseria gonorrhoeae (GC) Trichomonas vaginalis Mycoplasma genitalium bacterial vaginosis (BV)-related organisms (e.g., G. vaginalis) enteric bacteria (e.g., E. coli) (rare; more common in post-menopausal people) PID may be associated with no specific identifiable pathogen. EPIDEMIOLOGY PID is a significant public health problem. Up to 2/3 of cases go unrecognized, and under reporting is common. There are approximately 100,000 cases of symptomatic PID annually in Canada; however, PID is not a reportable infection so, exact

  • Risk Profile of Qatari Women Treated for Infertility in a Tertiary Hospital: a Case- Control Study Sarah Musa1 and Sherif Osman2,3*
    Musa and Osman Fertility Research and Practice (2020) 6:12 https://doi.org/10.1186/s40738-020-00080-5 RESEARCH ARTICLE Open Access Risk profile of Qatari women treated for infertility in a tertiary hospital: a case- control study Sarah Musa1 and Sherif Osman2,3* Abstract Background: Female infertility is a multifactorial condition constituting a worldwide public health problem. The ability to reproduce is an important product of any marriage, hence infertility may exert a negative impact on physical, financial, social and emotional wellbeing of affected couples. The cornerstone to the management of any disease, including infertility, is prevention. Identifying the modifiable risk factors of female infertility will aid at prevention, early detection, and treatment of medical conditions that can threaten fertility as well as promoting healthy behaviours that can preserve it. Aim: To explore the risk profile of infertility among Qatari women and compare risk factors distribution among primary vs. secondary infertility. Methodology: A hospital-based case control study was conducted from September 17th, 2017- February 10th, 2018. Cases (n = 136) were enrolled from infertility clinic and controls (pregnant women, n = 272), were enrolled from antenatal clinic, Women Hospital, Hamad Medical Corporation (HMC). Interview questionnaire was utilized to collect data about sociodemographic, risk factors related to infertility and patient health Questionnaire (PHQ)-2. Body Mass Index (BMI) was calculated.

The pathophysiology of pain in EM and AM comprises sensory and somatoform pain mechanisms. Over time, these may aggravate and lead to individual complex disease patterns if not diagnosed and treated. Despite the known facts, several years often pass between the onset of symptoms and diagnosis. Chronic pain disorders with changes on a neuronal level frequently arise and are linked to depressive disorders, with the process becoming a vicious cycle. Additionally, women with EM and AM suffer from sub- and infertility. Low fecundity rates are caused by anatomical changes in combination with behavioral changes in the sexual activity of women with chronic pain as well as local proinflammatory factors that not only decrease implantation rates but also promote early abortions.

BMC Urol (2021) 21:115 https://doi.org/10.1186/s12894-021-00878-5 CASE REPORT Open Access The perils of penile enhancement: case report of a fulminant penile infection Nicole Wen Mun Khor1,2* , Ankur Dhar1 and Alistair Cameron‑Strange1,2 Abstract Background: Penile enhancement with injectable agents is a rising trend and yet has received little scientifc atten‑ tion despite the potential for serious complications. These include cosmetic, functional and systemic complications that may require complex penile reconstructive surgery. We report a case of delayed severe infection following penile fller insertion leading to multi‑organ failure and intensive care support. Case presentation: A 31‑year‑old man presented with fevers and progressive pain and swelling of the penile shaft, 3 days after unprotected sexual intercourse. The patient received subcutaneous hyaluronic fller injections at a cos‑ metic clinic for penile enlargement two months prior to presentation. Relevant social history include polysubstance abuse and multiple sexual partners. Physical examination revealed gross penile oedema and erythema, with a ventral curvature of the penile shaft and a superfcial abrasion on the distal ventral penile shaft. Within 24 h the patient devel‑ oped septic shock with anuria, hypotension and fevers to 40 °C, requiring transfer to the Intensive Care Unit (ICU) for vasopressor and inotropic support. Intraoperative penile exploration revealed multiple pus stained fllers which were drained and grew Streptococcus Pyogenes on cultures. There was no abscess or evidence of necrotising fasciitis intra‑ operatively. The patient improved with intravenous antibiotics and was stepped down from the ICU after four days and discharged on day eight.

Urethral disorders, cystitis and interstitial cystitis may also cause painful intercourse. The location of the pain may be described as entry or deep. Vulvodynia, atrophy, inadequate lubrication and vaginismus are associated with painful entry. Deep pain occurs with the other con- ditions previously noted. The physical examination may reproduce the pain, such as localized pain with vulvar vestibulitis, when the vagina is touched with a cotton swab. The involuntary spasm of vaginismus may be noted with insertion of an examining finger or speculum. Palpation of the lateral vaginal walls, uterus, adnexa and urethral structures helps identify the cause. An understanding of the present organic etiology must be integrated with an appreciation of the ongoing psycho- logic factors and negative expectations and attitudes that perpetuate the pain cycle.
