ABSTRACT
Desmoid fibromatosis (DF) is a rare and locally aggressive neoplasm. We present a case of a 28-year-old previously healthy multigravida who noticed a lump in her abdomen near the umbilicus two months before becoming pregnant. It underwent rapid growth during pregnancy, causing pain and discomfort. Targeted ultrasound of the area showed an irregular mass measuring 0.9 × 1.7 × 1.4 cm. The origin of the mass was unclear, suggesting a connection with the intra-abdominal contents. An MRI done three weeks later revealed a subcutaneous ovoid mass measuring 3.0 × 2.3 × 3.0 cm, which was significantly larger. Due to pain and rapid growth, surgical resection was done at 25 weeks of pregnancy. Histopathological examination revealed a desmoid tumor. The patient had an uneventful recovery and term vaginal delivery without complications. Hence, our case serves as evidence that DF tumors can be surgically managed during pregnancy with minimal to no complications.
ABSTRACT
BACKGROUND: Trichomonas vaginalis is the most common nonviral sexually transmitted infection. However, because it is not a reportable disease in the United States, there is limited information on the age of infected individuals and their geographic distribution. OBJECTIVE: The purpose of this study was to evaluate the detection rates of T vaginalis infection compared with Chlamydia trachomatis by age and state in a commercial laboratory setting. STUDY DESIGN: Quantitative real-time polymerase chain reactions were used to detect the presence of T vaginalis and C trachomatis in cervicovaginal samples that were obtained during gynecologic examinations. A total of 1,554,966 and 1,999,077 samples from females 10-79 years old were analyzed retrospectively for the presence of T vaginalis and C trachomatis, respectively. RESULTS: The highest detection rate of an infection with T vaginalis was ages 47-53 years. For C trachomatis, the highest detection rate was ages 14-20 years. T vaginalis detection rate distribution by age shows a bimodal pattern with first peak at ages 21-22 years (4.0-4.1%) and a higher second peak at ages 48-51 years (5.4-5.8%). C trachomatis prevalence distribution by age shows a maximum peak of 8.6% at age 17 years and a rapid decline thereafter. In general, the detection rates of both pathogens were higher in the southeast and in states along the Mississippi River Valley than in other parts of the country. A nucleotide polymorphism associated with T vaginalis metronidazole resistance (ntr6TVK80STOP) was not associated with age and was found most frequently in specimens from New Mexico and Vermont. CONCLUSIONS: The detection rate of T vaginalis does not appear to decrease with age as observed for C trachomatis and reaches maximum rates in women 48-51 years old. The geographic distribution of T vaginalis appears to be broadly similar to that of other sexually transmitted diseases. The ntr6TVK80STOP polymorphism did not have a specific association with age or geography.

Rare adverse effects of India ink injection spillage during colonoscopy have been reported. We present a case report in which prior colonoscopic India ink tattooing was found to mimic intraperitoneal endometriosis in a 48 year-old woman undergoing laparoscopic sterilization. Multiple black lesions suspicious for endometriosis involving the anterior and posterior cul-de-sac, left ovary, and omentum were found. A pathological assessment showed peritoneal tissue with focal dark pigment associated with mild chronic inflammation and deposition of tattoo pigment; there was no evidence of endometriosis in the specimens. Surgical recognition of tattoo ink spillage in the peritoneum is very important to prevent misinterpretation of peritoneal findings.

OBJECTIVE: The study aimed to compare the overall detection rate of Trichomonas vaginalis to Chlamydia trachomatis and Neiserria gonorrhea and report detection rates by age groups. MATERIALS AND METHODS: Real-time polymerase chain reaction was used to detect the presence of T. vaginalis, C. trachomatis, and N. gonorrhea in cervical samples obtained from patients during gynecological examinations. A total of 78,428, 119,451, and 117,494 samples from women age 12 to 75 years were retrospectively analyzed for the presence of T. vaginalis, C. trachomatis, and N. gonorrhea, respectively. T. vaginalis and C. trachomatis detection rates in Florida, New Jersey, and Texas were calculated in different age groups. RESULTS: The overall detection rate was 4.3% for T. vaginalis, 3.8% for C. trachomatis, and 0.6% for N. gonorrhea. The overall detection rate of T. vaginalis in Florida was 4.7% (n = 22,504), in New Jersey was 3.6% (n = 22,249), and in Texas was 4.5% (n = 33,675). Calculation of infection rates with T. vaginalis revealed differences between selected age groups with the highest detection rates in all 3 states found in age group 46 to 55 years (6.2%), which was higher than the overall detection rates in other age groups (p < .05 for all states). For C. trachomatis, the highest detection rate was found in age group 12 to 25 years (7.3%). CONCLUSIONS: The overall infection rates of T. vaginalis were higher compared with those of C. trachomatis and N. gonorrhea. Detection rates of T. vaginalis were found to be highest among women age 46 to 55 years and may be due to T. vaginalis infiltrating the subepithelial glands and being detected only during hormone-induced or antibiotic-induced changes in the vaginal flora.

Success rate in human pregnancies is believed to be very low and sex-specific mechanisms may operate in prenatal loss. Assuming a sex-differential in prenatal loss exists, we examined genetic markers in biologically plausible targets in the HLA complex, other immune system-related and iron-regulatory genes in 388 healthy newborns from Wales (UK) using one sex as a control group for the other. Genotyping of 333 single nucleotide polymorphisms (SNPs) from 107 genes was achieved mainly by TaqMan assays. Twenty-two of autosomal SNPs showed frequency differences between 187 male and 201 female newborns either individually or as part of a haplotype. Of these, six markers (RXRB rs2076310, HLA complex haplotype HLA-DQA1 rs1142316-HLA-DRA rs7192-HSPA1B rs1061581, HIST1H1T rs198844, IFNG rs2069727, NKG2D rs10772266 and IRF4 heterozygosity) showed statistically robust differences between male and female newborns and multivariable modeling confirmed their independence. There were fewer males homozygote for combined wildtype genotypes of LIF rs929271, TP53 rs1042522 and MDM2 rs2279744 compared with females [OR = 0.3, 95% confidence interval (CI) = 0.1-0.8; P < 0.01] although these SNPs did not show any association individually. It is unlikely that SNPs have clinical utility as single markers in any trait with complex etiology but polygenic predictive models remain a possibility. If their validity is confirmed in larger studies of different populations and functional mechanisms of these preliminary associations are elucidated, these markers from the HLA complex, NKG2D region and cytokines may cumulatively have sufficient predictive value for susceptibility to prenatal selection in each sex.

OBJECTIVE: To present the detection rates of Candida species in vaginal samples from patients visiting physicians. METHODS: The presence of C. albicans, C. glabrata, C. parapsilosis and C. tropicalis in 3978 vaginal swabs from patients in six US states was detected by PCR amplification. RESULTS: Candida DNA was detected in 33.1% of the population studied. Of the 1316 positive samples, 80.2% contained C. albicans, 14.3% contained C. glabrata, 5.9% contained C. parapsilosis and 8.0% contained C. tropicalis. Comparing samples by patients' state of residence revealed an association with the detection of C. glabrata (p = 0.029). Comparing samples by patients' age revealed a decrease in the overall detection of Candida (p < 0.001) and C. albicans (p < 0.001), concomitant with an increase in the detection of C. glabrata (p < 0.001) and C. parapsilosis (p = 0.025). CONCLUSIONS: These results provide geographic- and age-specific data on four Candida species associated with vaginitis.
