Cytokine profiles and their roles in development of provoked vulvodynia.

Provoked, localized, vulvodynia (PVD) is the main subtype of vulvodynia. Although the etiology of PVD is still a topic of debate, inflammation caused by cytokines responding to a dysregulated microbiome is one of the leading proposed theories. Therefore, the purpose of our study is to further explore the cytokine profiles in the study group with PVD using multiplex immunoassays based on electrochemiluminescence. We compared a panel of 26 distinct cytokines levels in the study group with PVD (n = 23) to the control group (n = 18) and cytokine concentrations were measured using MESO QuickPlex SQ 120 instrument with 5 different multiplex assays. Statistical analysis used the Mann-Whitney U test, two-sided p-values, and a significance level of α = 0.05. Differences in cytokine concentrations are described as negligible, small, medium, or large based on Cliff's δ. Concentrations of three cytokines were significantly lower in the PVD group: a large difference in IP-10 (p = 0.029*) and medium differences in IL-1RA4 (p = 0.030*) and IL-12 (p = 0.034*). One cytokine level was significantly higher in the PVD group: a medium difference for IL-6 (p = 0.037*). Due to the lack of consistency in elevation of inflammatory profiles, it is not enough to support persistent inflammation as the etiology behind PVD. However, these findings may indicate there is a possible immune response deficiency in some patients who have PVD. The resemblance of cytokine profile in our study to cytokine profile of people with chronic yeast infection further support this proposed mechanism behind PVD. Future studies involving history and testing for yeast infection are necessary to explore this possibility further.

Pubic Candida Folliculitis, A Case Report in a Patient With Recurrent Vaginal Candidiasis.

Objective: Folliculitis is a skin infection and inflammation that develops in the hair follicles. While most cases of folliculitis are caused by bacterial infections, here is a case of folliculitis caused by the Candida fungi in an immunocompetent host. Case report: A 23-year-old non-diabetic immunocompetent female with recurrent vaginal candidiasis developed clusters of erythematous, pruritic papules in the pubic area. Upon evaluation, the clusters were determined to be folliculitis. Risk factors for folliculitis included shaving of the pubic area, hot tub use, and wearing of tight, restrictive clothing. Cultures and skin samples of the folliculitis demonstrated Candida albicans. The patient was subsequently and successfully treated with clotrimazole solution and cream. There was no recurrence of the folliculitis upon her 3-month follow-up appointment. Conclusion: Candida folliculitis is a rare condition in non-diabetic patients. The patient's history, risk factors and immune status assessment, and physical examination with proper diagnostic testing, are crucial steps in attaining the correct diagnosis.

Vulvar Neurodermatitis in a Postmenopausal African-American Patient: A Case Report.

Lichen simplex chronicus commonly presents as a distressing vaginal lesion caused by severe, cyclical itch-scratch behavior. Lichen simplex chronicus is diagnosed by obtaining a detailed medical history, performing a physical exam, and recording of self-reported symptoms. Lichen simplex chronicus can be treated by corticosteroids, immunomodulators, antiepileptics, antihistamines, antidepressants, and phototherapy. Our case describes a 55-year-old female patient who presented to a clinic with recurrent vaginal itching, combined with compulsive scratching behavior that disrupted daily functioning. Physical examination revealed hypertrophic nodules located on the labia minora with scaling and hyperpigmentation. And the patient was diagnosed with lichen simplex chronicus. Empirical treatment with behavioral modifications and clobetasol propionate cream with an occlusive dressing produced significant improvements in symptoms at a six-month follow-up. Lichen simplex chronicus can have unusual presentations and; therefore, must be carefully differentiated from infectious and malignant skin lesions.

Preterm Complete Uterine Rupture With En Caul Expulsion.

Spontaneous uterine rupture is a catastrophic obstetric complication for both the mother and fetus. We highlight a case of a 32-year-old G2P1A0L1 Hispanic female at 36 weeks gestation who presented to the labor and delivery unit with minimal prenatal care, complaining of abdominal pains and vaginal bleeding. An abdominopelvic ultrasound confirmed an empty uterus and fetal demise in the abdominal cavity, leading to an exploratory laparotomy to evacuate the fetus. At surgery, a preterm sized fetus "en caul" with intact amnions was floating in the abdominal cavity and a hemostatic, complete rupture of the anterior uterine wall was discovered. Uterus was repaired and the patient recovered postoperatively without complications. Despite the best evidence suggesting that a history of low-transverse Cesarean section poses a low risk for spontaneous uterine rupture, this complication should always be considered and patients should be counseled regardless of the low risk should they desire a cesarean section.

Lactobacilli and Cytokine Modifications during Menopause and Their Relation to Vulvar and Vulvovaginal Disorders.

OBJECTIVES: Female sexual and reproductive health is heavily influenced by the levels and ratios of Lactobacilli species and vaginal cytokines. Menopause marks a profound body change as it shifts to a natural and permanent non-reproductive state. Vulvovaginal diseases encompass a broad variety of sexual health conditions. Furthermore, both menopause and vulvovaginal diseases affect vaginal Lactobacilli and cytokine levels. Thus, this study aimed to investigate the correlation between menopause, vulvovaginal diseases, and vaginal Lactobacilli and cytokine levels. METHODS: Vaginal swab samples were collected as part of a prospective data bank creation to study vaginal conditions as approved by the Institutional Review Board of Texas Tech University Health Sciences Center, Lubbock, USA. This study utilized 38 samples in this database, which were assigned to the pre-menopausal with no vulvovaginal conditions (n = 20) and post-menopausal with vulvovaginal conditions (n = 18) groups. A real-time polymerase chain reaction was conducted to determine the relative concentration of Lactobacilli species, while cytokine analysis was performed using multiplex enzyme-linked immunosorbent assay immunoassay. The standardized mean difference, multivariate analysis of variance, and permutational unequal variance t test were used for the statistical analysis. RESULTS: Cytokines, interleukin (IL)-6, macrophage inflammatory protein-1α, IL-8, and Lactobacillus iners expression were significantly elevated in the control group compared to the study group (P = 0.03 for the cytokines, P = 0.0194 for Lactobacilli). CONCLUSIONS: The levels of vaginal cytokine and Lactobacillus profile were significantly different between the pre-menopausal and post-menopausal groups.

Challenging Vaginal Discharge, Lactobacillosis and Cytolytic Vaginitis.

In women's health, clinicians are often faced with diagnosing and administering treatment to patients who present with an increased vaginal discharge without much other information to work with. It's only once a patient's background is reviewed and lab work is completed that two common reasons behind vaginal discharge with similar symptoms, Lactobacillosis and Cytolytic Vaginitis, can be differentiated and a proper diagnosis can be reached. Now, we understand that Lactobacillosis and Cytolytic Vaginitis are symptomatically confused by patients as well as inexperienced clinicians. Lactobacillosis involves the presence of abnormal, extremely long Lactobacilli, a keystone species for vaginal health, while Cytolytic Vaginitis mainly involves, increased Lactobacilli, pH between 3.5 and 4.5, presence of cytolysis, and a lowered white blood cell count. Both present with similar discharge, leading to their conflation. A microscopic examination of the discharge using a wet mount with normal saline can provide 80% diagnostic sensitivity until further testing can be completed.

A rare case report: Cutaneous Candida tropicalis infection disguised as a sacral decubitus rash in an immunocompetent individual.

Candida infection is seen in patients with weak or disrupted host responses. Cutaneous candidiasis typically affects the intertriginous areas and presents with a red plaque surrounded by satellite lesions. Diagnosis of cutaneous candidiasis is made by visual inspection followed by potassium hydroxide normal saline microscopic preparation (wet mount) and polymerase chain reaction identification or culture of fungal organism. The following case describes a 38-year-old patient with limited mobility who presented with a peri sacral lesion that was first assumed to be a decubitus ulcer by nursing facility staff, but proved to be a cutaneous infection by Candida tropicalis, a less common Candida species. The unusual location as well as the characteristic C. tropicalis micro- and macroscopic appearance are described which ultimately led to the diagnosis of a cutaneous fungal infection in an otherwise immunocompetent individual that was resolved with fluconazole therapy. Our case report emphasizes the need for early diagnosis of cutaneous lesions in patients with limited mobility in consideration that not all Candida species thrive in similar environments and can present in unusual locations of the human body. Although rare, C. tropicalis could be found in this vulnerable population.

Cytokine profiles and Lactobacillus species presence in pre-menopausal subjects with genital Mycoplasma genitalium or Ureaplasma urealyticum colonization.

BACKGROUND AND PURPOSE: Lactobacilli play a vital role in protecting the vagina against pathogens. Cytokines are vital components of defense against infections in women. The genital mycoplasmas, Mycoplasma genitalium and Ureaplasma urealyticum, are associated with various infectious diseases in adults and infants. The objective of our study is to identify differences in cytokine profile and Lactobacillus species dominance between a study group of non-pregnant pre-menopausal women with genital M. genitalium or U. urealyticum colonization and a control group of non-pregnant pre-menopausal women without genital M. genitalium or U. urealyticum colonization. METHODS: A real-time polymerase chain reaction was performed to measure Lactobacillus species in vaginal swab samples. Cytokine analysis was performed using multiplex immunoassay techniques. Analysis of variance confirmed a significant difference in cytokine profiles between patient groups, with t-tests identifying the most significantly different cytokines. Categorical data analysis identified significant patterns of relative Lactobacillus species dominance in the study group. RESULTS: Lactobacillus iners was the predominant Lactobacillus species in the control group (p = 0.005). There were no dominant Lactobacillus species observed in the study group. Vascular endothelial growth factor A (p = 0.002), interleukin-8 (p = 0.001), and interleukin-1ß (p = 0.049) were expressed significantly higher in the study group, whereas interleukin-1 receptor antagonist (p < 0.001), interleukin-10 (p = 0.001), interleukin-12 (p = 0.002), and interferon-γ (p = 0.022) were expressed higher in the control group. Association matrices for cytokines were significantly different between two groups (p < 0.001), with mostly negative associations in the control group and mostly positive associations in the study group. CONCLUSION: Cytokine levels, their associations, and the patterns of Lactobacillus species dominance are observed to significantly diverge on the basis of M. genitalium and U. urealyticum colonization among non-pregnant pre-menopausal women.

The Association Between the Mechanical Ventilator Pressures and Outcomes in a Cohort of Patients with Acute Respiratory Failure.

BACKGROUND: Pressures measured during mechanical ventilation provide important information about the respiratory system mechanics and can help predict outcomes. METHODS: The electronic medical records of patients hospitalized between 2010 and 2016 with sepsis who required mechanical ventilation were reviewed to collect demographic information, clinical information, management requirements, and outcomes, such as mortality, ICU length of stay, and hospital length of stay. Mechanical ventilation pressures were recorded on the second full day of hospitalization. RESULTS: This study included 312 adult patients. The mean age is 59.1 ± 16.3 years; 57.4% were men. The mean BMI was 29.3 ± 10.7. Some patients had pulmonary infections (46.2%), and some patients had extrapulmonary infections (34.9%). The overall mortality was 42.6%. In a multi-variable model that included age, gender, number of comorbidities, APACHE 2 score, and PaO2/FiO2 ratio, peak pressure, plateau pressure, driving pressure, and PEEP all predicted mortality when entered into the model separately. There was an increase in peak pressure, plateau pressure, and driving pressure across BMI categories ranging from underweight to obese. CONCLUSIONS: This study demonstrates that ventilator pressure measurements made early during the management of patients with acute respiratory failure requiring mechanical ventilation provide prognostic information regarding outcomes, including mortality. Patients with high mechanical ventilator pressures during the early course of their acute respiratory failure require more attention to identify reversible disease processes when possible. In addition, increased BMIs are associated with increased ventilator pressures, and this increases the complexity of the clinical evaluation in the management of obese patients.
