Comparison of Short-Duration and Chronic Premenarchal Vulvar Complaints

Study ObjectiveTo compare clinical characteristics, treatment histories, and microbiology of premenarchal girls who presented to a pediatric gynecology specialty clinic with short-duration and chronic vulvar symptoms.DesignRetrospective cohort study.SettingPediatric and adolescent gynecology clinic at a tertiary care children's hospital.ParticipantsOne hundred eighty-two premenarchal patients ages 2-14 years who presented to a pediatric gynecology specialty clinic with vulvar complaints and who were evaluated with a yeast and/or bacterial culture.InterventionsNone.Main Outcome MeasuresChronic and short-duration vulvar symptoms, microbiology, and diagnosis.ResultsPatients with chronic symptoms were more likely to present with itching (59/102 (57.8%) vs 34/80 (42.5%); P = .04), redness or rash (53/102 (52.0%) vs 22/80 (27.5%); P = .0009), and discomfort (59/102 (57.8%) vs 30/80 (37.5%); P = .006), compared with patients with short-duration symptoms. Overall, 44.5% of patients had a history of antifungal treatment, with a greater proportion of patients with chronic symptoms having received antifungal treatment compared with those with short-duration symptoms (53/102 (52.0%) vs 28/80 (35.0%); P = .02). Despite a history of antifungal treatment in nearly half of the patients, Candida albicans was isolated in only 3/144 (2.1%) yeast cultures. Bacterial vulvar cultures were positive in 75/159 (47.2%), and there was no difference among the symptom duration groups (38/71 (53.5%) vs 37/88 (42.1%); P = .15).ConclusionVulvovaginitis is a common gynecological diagnosis among premenarchal girls with short-duration and chronic vulvar symptoms. Regardless of symptom duration, yeast cultures are rarely positive. Antifungal treatment should be avoided in toilet-trained prepubertal girls.     

Apendicitis aguda y teratoma: ¿causalidad o consecuencia?

Gynaecological disorders can have a wide variety of clinical manifestations.The coexistence of teratoma and acute appendicitis accounts for unusual, but not exclusive, percentage of abdominal pathology in young women. There are virtually no reviews or documented cases in the literature, so it is unknown whether there is causality between the 2 or simply a coincidence.The case is presented of a young patient whose main symptom was diffuse abdominal pain with great clinical and radiological discordance. Surgical intervention was required to confirm the presence of both pathologies after the completion of the histopathology study.     

Resultados perinatales en 492 presentaciones podálicas: cesárea vs. parto vaginal

Objective

To analyze the perinatal results in our hospital comparing vaginal delivery and cesarean section in breech presentation singleton pregnancies at term.

Material and Methods

All live ante-partum singleton fetuses in breech presentation, at 37 to 41+6 weeks and days who delivered between July 2006 and August 2010 were included in the study. We compared perinatal results between cesarean section and vaginal delivery.

Results

There were no differences in Apgar score at 5 minutes < 7, pH umbilical cord < 7, base deficits and lactate, neonatal intensive care unit admission or perinatal mortality.

Conclusions

With appropriate maternal and fetal conditions and a qualified medical team, a breech vaginal delivery could be propose obtaining good perinatal outcomes.     

Fine-needle aspiration of six carotid body paragangliomas

We report six carotid body paragangliomas diagnosed by fine-needle aspiration (FNA) in five patients. A total of eight aspirations were performed. The cytologic findings are characteristic: hemorrhagic background, hypo- to hypercellular smears (depending on the skill of the aspirator) with cells having delicate, illdefined, vacuolated cytoplasm, pleomorphic nuclei with distinct nucleoli, rare intranuclear cytoplasmic inclusions, and prominent rosette formation. No complications arose in any of the eight aspirations. FNA is a safe, accurate means of diagnosing carotid body paragangliomas. It can provide essential information for treatment planning and patient management.     

“Cellular adenomatoid nodules” of the thyroid: Review of 219 fine-needle aspirates

We reviewed 219 consecutive thyroid aspirates previously diagnosed as “cellular adenomatoid nodule.” applying the criteria presented in this paper and reclassifying them as 146 adenomatoid nodules (AN), 31 cellular adenomatoid nodules (CELL-AN), 29 cellular adenomatoid nodules vs. follicular neoplasms (CELL-AN vs. FN), 5 follicular neoplasms (FN), 2 FN of oxyphilic cell type, 4 papillary carcinomas, and 2 chronic lymphocytic (Hashimoto's) thyroiditis. Of the 146 adenomatoid nodules, 14 occurred in multinodular goiters on histologic examination. Of the 31 CELL-AN, five had surgery: two were follicular adenomas, one was papillary carcinoma, and two were multinodular goiters. Of the 29 CELL-AN vs. FN, 11 had surgery: six were follicular adenomas, two were follicular carcinomas, two were multinodular goiters, and one was Hashimoto's thyroiditis. Surgery on four FN showed follicular adenomas (a fifth patient was lost to follow-up). Of the two FN of oxyphilic cell type, one was a multinodular goiter and the other a follicular adenoma with oxyphilic cells. Three of the four papillary carcinomas were confirmed histologically (one patient was lost to follow-up). Of the two cases showing Hashimoto's thyroiditis, one was diagnosed as FN on repeat aspiration and follicular carcinoma at surgery. After review, we identified 40 patients at higher risk of harboring a neoplasm and 31 with cellular adenomatoid nodules. Twenty-five underwent surgery with the above results. In the classification of follicular lesions of the thyroid by FNA, adherence to strict cytologic criteria helps identify those patients who will benefit most from surgery.     

Therapeutic Consequences of Variation in Intraarterial Pressure Measurements After Iliac Angioplasty

Purpose: To assess the accuracy of intraarterial measurement of transstenotic pressure gradients for the detection of hemodynamically suboptimal iliac angioplasty. Methods: In 14 patients, referred for diagnostic angiography, mean pressure gradients in the aorta and iliac artery were obtained twice, using a double-sensor pressure catheter. Additional iliac measurements were performed during pharmacologically induced flow augmentation. Repeatability was assessed by calculation of the mean difference plus standard deviation (MD ± SD) and repeatability coefficient (2 × SD). These results were extrapolated to 137 iliac angioplasty procedures with secondary stenting where there was a residual pressure gradient > 10 mmHg. Results: MD ± SD for repeated measurements at rest and during flow augmentation were 0 ± 2 mmHg and 1 ± 3 mmHg, respectively. Repeatability coefficients were 3 and 6 mmHg. Mean pressure gradients after hemodynamically insufficient angioplasty were 8 ± 7 mmHg at rest and 17 ± 5 mmHg following vasodilatation. Inaccurate pressure recordings may have led to inappropriate stent placement in less than 2.5%, and inappropriate denial of stent placement in less than 5% of the lesions. Conclusion: Variability of intraarterial pressure measurements has little consequence in the detection of hemodynamically significant stenosis after angioplasty.

Bioenergetics and intermuscular fat in chronic obstructive pulmonary disease‐associated quadriceps weakness

Introduction: Chronic obstructive pulmonary disease (COPD) is associated with metabolic abnormalities in muscles of the lower limbs, but it is not known whether these abnormalities are generalized or limited to specific muscle groups, nor is there an easy way of predicting their presence. Methods: Metabolism in the quadriceps and biceps of 14 COPD patients and controls was assessed during sustained contraction using 31‐phosphorus magnetic resonance spectroscopy (³¹P MRS). T1 MRI was used to measure quadriceps intermuscular adipose tissue (IMAT). Results: COPD patients had prolonged quadriceps phosphocreatine time (patients: 38.8 ± 12.7 s; controls: 25.2 ± 10.6 s; P = 0.006) and a lower pH (patents: 6.88 ± 0.1; controls: 6.99 ± 0.06; P = 0.002). Biceps measures were not significantly different. IMAT was associated with a nadir pH <7.0 (area under the curve = 0.84). Conclusions: Anaerobic metabolism during contraction was characteristic of quadriceps, but not biceps, muscles of patients with COPD and was associated with increased IMAT. Because IMAT can be assessed quickly by conventional MRI, it may be a useful approach for identifying patients with abnormal muscle bioenergetics. Muscle Nerve 51 : 214–221, 2015     

Association study of 44 candidate genes with depressive and anxiety symptoms in post-partum women

The post-partum period is a time of extreme vulnerability for a whole spectrum of psychiatric disorders. Delivery may be considered an important risk factor in genetically susceptible women. Five hundred and eight SNPs in 44 genes at candidate pathways putatively related to mood changes after delivery were genotyped in a multicenter cohort of 1804 women from Spain. Participants completed two scales at 2-3 days, 8 weeks, and 32 weeks post-partum, the Edinburgh Post-partum Depression Scale (EPDS) and the Spielberger State-Trait Anxiety Inventory (STAI). Those women who scored 9 or more on EPDS were evaluated for major depression using the Diagnostic Interview for Genetics Studies (DIGS) adapted for post-partum depression. Association with major depression was assessed using likelihood ratio tests under a codominant genotype model. Association with scale scores was tested using linear mixed models to take into account repeated measures over time. Two intronic SNPs, one at the serotonin transporter gene (SLC6A4) and another at dopa decarboxylase (DDC), were significantly associated to STAI anxiety scores after multiple testing correction (nominal P = 0.0000513 and 0.000097, respectively). In addition, post hoc analysis at the unphased haplotype level using nominal significant SNPs revealed an association with a combination of three SNPs at protein kinase C, beta (PRKCB) with major depression, significant after multiple testing correction (nominal global P = 0.0001596). In conclusion, we detected a role of SLC6A4 in mood changes after stressful events, and revealed new putative associations involving DDC and PRKCB. Therefore, these genes deserve further investigation to confirm these results.     

Cx3cr1‐deficiency exacerbates alpha‐synuclein‐A53T induced neuroinflammation and neurodegeneration in a mouse model of Parkinson's disease

Parkinson's disease (PD) is the second most common neurodegenerative disorder characterized by the degeneration of dopaminergic neurons of the substantia nigra and the accumulation of protein aggregates, called Lewy bodies, where the most abundant is alpha‐synuclein (α‐SYN). Mutations of the gene that codes for α‐SYN (SNCA), such as the A53T mutation, and duplications of the gene generate cases of PD with autosomal dominant inheritance. As a result of the association of inflammation with the neurodegeneration of PD, we analyzed whether overexpression of wild‐type α‐SYN (α‐SYN^WT) or mutated α‐SYN (α‐SYN^A53T) are involved in the neuronal dopaminergic loss and inflammation process, along with the role of the chemokine fractalkine (CX3CL1) and its receptor (CX3CR1). We generated in vivo murine models overexpressing human α‐SYN^WT or α‐SYN^A53T in wild type (Cx3cr1^+/+) or deficient (Cx3cr1^–/–) mice for CX3CR1 using unilateral intracerebral injection of adeno‐associated viral vectors. No changes in CX3CL1 levels were observed by immunofluorescence or analysis by qRT‐PCR in this model. Interestingly, the expression α‐SYN^WT induced dopaminergic neuronal death to a similar degree in both genotypes. However, the expression of α‐SYN^A53T produced an exacerbated neurodegeneration, enhanced in the Cx3cr1^–/– mice. This neurodegeneration was accompanied by an increase in neuroinflammation and microgliosis as well as the production of pro‐inflammatory markers, which were exacerbated in Cx3cr1^–/– mice overexpressing α‐SYN^A53T. Furthermore, we observed that in primary microglia CX3CR1 was a critical factor in the modulation of microglial dynamics in response to α‐SYN^WT or α‐SYN^A53T. Altogether, our study reveals that CX3CR1 plays an essential role in neuroinflammation induced by α‐SYN^A53T.     

Diseño de una vía clínica para la atención a los pacientes con esclerosis múltiple

IntroductionClinical pathways are standard health care methods to coordinate clinical work, reduce inter-clinician variability, improve patient care and increase staff and patient satisfaction. The aim of this study is to develop a clinical pathway capable of organising and developing standard procedures for diagnosis, treatment and care in patients with multiple sclerosis and to coordinate all medical specialists involved in this disease.MethodsA multidisciplinary unit for the care of MS patients was developed. All of them and quality specialists analysed some international evidence-based studies, clinical guides, international guidelines and other clinical neurological pathways in several meetings and designed several documents for the clinical pathways.ResultsA clinical pathway was created consisting of a scientific-technical framework, which arranges the care in relation to the diagnosis and reatment. The framework is accompanied by various patient-information documents on the disease, an information sheet on diagnostic procedures and a map of the process. Quality standards were established to achieve continuous improvement in patient care.ConclusionsA clinical pathway for the care of MS patients in a multidisciplinary unit homogenises and organises the care which the MSpatient should receive from the initial symptoms to the progressive stages. This clinical pathway improves the quality of patient care, reduces the variability in work protocols and rationalises the use of the available health care resources.
