The aim of the study was to determine whether the genitourinary microbiome differs between and within women with and without pubic hair.

Premenopausal women who self-identified into 2 groups were recruited in the "hair" group, women did not remove any pubic hair, and in the "bare" group, all pubic hair was removed routinely. Participants submitted a vaginal swab, a voided urine sample, and a catheterized urine sample, and then "crossed over." The "hair" group removed all hair for 1 month, and the "bare" group grew hair for 2 months. After crossover, participants again submitted a vaginal swab, a voided urine sample, and a catheterized urine sample. Ten participants acted as controls. DNA was extracted, and the V4 region of 16S rRNA gene was amplified and sequenced using the MiSeq platform. Paired-end sequences were imported into QIIME2-2018.6. Alpha diversity (the number and proportion of species in an individual sample) and beta diversity (differences in microbial composition between samples) were evaluated.

Forty-two participants were analyzed 16 "bare to hair" crossovers, 16 "hair-to-bare" crossovers, and 10 controls. The microbiome varied by sample type vaginal swabs had the lowest alpha diversity and catheterized urine had the highest (P < 0.001). At baseline, there were no differences in the alpha or beta diversity of urine or vaginal microbiomes between groups. Vaginal beta diversity at visit 2 was greater within crossovers than controls (P = 0.004), suggesting that altering hair status alters the microbiome composition. Urinary beta diversity was not different at visit 2 (P = 0.40).

Pubic hair status does not determine one's baseline genitourinary microbiome, but women who change their hair status may alter their vaginal microbiome.

To compare the perioperative outcomes of transvaginal/perineal and abdominal approaches to rectovaginal fistula (RVF) repair using a national multicenter cohort.

The American College of Surgeons National Surgical Quality Improvement Program database was utilized to identify women undergoing RVF repair from 2005 to 2016. Emergent cases and those with concomitant bowel diversion were excluded. Baseline patient demographics, procedure characteristics, 30-day postoperative complications, return to the operating room, and readmission were evaluated. Baseline characteristics were compared across surgical approach. Multivariable logistic regression models identified preoperative characteristics independently associated with postoperative complications.

A total of 2288 women underwent RVF repair 1560 (68.2%) via transvaginal/perineal approach and 728 (31.8%) via abdominal approach. Patients undergoing transvaginal/perineal repair were significantly younger (median age, 46 years vs 63 years), with lower Americanch were older with more comorbidities and had higher postoperative complications rates, likely secondary to underlying differences in the treated populations. Irrespective of surgical approach, ASA class, disseminated cancer, and preoperative anemia were associated with higher postoperative morbidity. This may enhance preoperative counseling and allow for careful patient selection.Intrahepatic cholangiocarcinomas (ICCs) show morphologic diversity, ranging from tumors composed of nonmucinous small ducts to mucin-producing large duct tumors to tumors with mixed hepatocellular carcinoma features. Diagnosing ICCs can be difficult, especially on biopsy, not only because of the morphologic diversity, but also because metastatic tumors are often in the differential diagnosis. Recently, branched DNA-based albumin RNA in situ hybridization (ISH) has been shown to be a potential sensitive and specific marker for ICC with 99% sensitivity. Niraparib Using a different RNA ISH technology, we evaluated the expression of albumin RNA ISH in ICC. We performed RNA ISH for albumin using RNAscope on 43 ICCs in a triplicate tissue microarray. Albumin RNA ISH was positive in 18 of 43 (42%) ICCs. Five of the 6 (83%) combined hepatocellular carcinoma-CC were positive in the CC component. None of the tumors with mucin production were positive (0/9). In our cohort, albumin RNA ISH showed a sensitivity of 42% in ICCs, supporting the morphologic diversity of ICCs. Albumin RNA ISH does not appear to be a highly sensitive marker for ICC and hence cannot be used as a stand-alone marker for ICC.
The aim is to study the utility of fine-needle aspiration cytology (FNAC) in preoperative diagnosis of bone lesions in correlation with radiological and histopathological findings and to determine the spectrum and morphological features of various bone lesions on FNAC.

A total of 275 cases of bone lesions were studied by FNAC over a period of 3 years. 196 procedures were performed by pathologists, and 107 procedures were guided. Cytology findings were correlated with that of histology on cellblocks or on subsequent surgical biopsies. Immunohistochemistry (IHC) was done wherever necessary.

Of the 275 cases, 49 lesions were inflammatory/infectious (granulomatous inflammation-19, nonspecific osteomyelitis-26, and fungal etiology-4), 16 were tumors of undefined neoplastic nature (aneurysmal bone cysts-12, and Langerhans cell histiocytosis-4), 99 lesions were benign (osteoblastoma-6, enchondroma-3, chondroblastoma-14, chondromyxoid fibroma-2, and Giant cell tumor-74), and 111 lesions were malignant (Osteosarcoma-36, chondrosarcoma-7, Ewing's sarcoma-28, lymphomas-4, plasma cell neoplasm-6, adamantinoma of long bone-1, and metastasis-29). Male to female ratio was 21, and the age range was between 4 and 84 years. Correlation with histology/cellblock was available in 149 tumors. Metastasis and round cell tumors such as Ewing's sarcoma and lymphoma were differentiated by IHC. The accuracy rate in cytological diagnosis of all bone lesions was 87.9% and for neoplasms was 93%. The discordance in the rest of the cases was due to inadequate cell material, and there were no false positives.

We conclude that FNAC is a simple and accurate preoperative diagnostic technique for assessment of bone tumors.
