Vesico-uterine fistulas represent a rare type of genito-urinary fistulas; however, due to the increasing incidence of Caesarean section (C-section) in the last decade, this abnormal communication between the urinary and genital tracts has been reported more often after such surgical procedures. The aim of the current article was to report the case of a 28-year-old patient who was submitted to surgery for a vesico-uterine fistula seven years after a C-section.

The 28-year-old patient with a previous history of four vaginal deliveries and one C-section was self-presented to the Gynecology Department for cyclic hematuria and diagnosed with a vesico-uterine fistula after injecting methylene blue in the uterine cavity during hysteroscopy. The patient was further submitted to surgery, and a parcelar myometrectomy en bloc with parcelar cystectomy, cystography, and prophylactic salpingectomy was performed. The postoperative outcome was uneventful.

Although vesico-uterine fistulas represent rare events, they should be considered, especially in young patients with a previous history of C-section.

Breast cancer often metastasizes to the lungs, bones, liver, and brain, colon metastasis from breast cancer (CMBC) is extremely rare.

The patient was a 63-year-old female. Mastectomy had been performed for breast cancer (pStage IIB) 15 years earlier at another hospital. Metastasis to the lumbar spine had been detected 4 years prior to referral to us and the patient had undergone hormonal therapy with an aromatase inhibitor. Furthermore, early primary sigmoid colon cancer had been endoscopically resected 2 years before referral. The patient was diagnosed with cancer recurrence in the colon at follow-up examinations performed 2 years after that endoscopic resection. After referral to our hospital, laparoscopic sigmoidectomy was performed. Based on the histopathological examination and immunohistological staining results (positive for cytokeratin 7, GATA-binding protein 3, estrogen receptor and human epidermal growth factor receptor-related 2 (2+); negative for cytokeratin 20, progesterone receptor, E-cadherin, gross cystic disease fluid protein 15 and caudal-related homeobox 2) the final pathological diagnosis was CMBC.

Although extremely rare, the possibility of CMBC should be considered in the case of colonic tumors in patients with a history of breast cancer.

Mucinous tubular and spindle cell carcinoma (MTSCC) is a rare subtype of renal cell carcinoma and generally considered a low-grade renal epithelial neoplasm. However, MTSCC with distant metastases often shows a poor prognosis. This is the first reported case of cytoreductive nephrectomy after nivolumab plus ipilimumab combination treatment.

A 26-year-old man had a 72-mm tumor at the left kidney with multiple osteolytic bone metastases. A biopsy of the renal tumor and bone metastases resulted in the diagnosis of MTSCC of the kidney with bone metastases. After nivolumab plus ipilimumab combined treatment, he underwent cytoreductive nephrectomy. The excised specimen showed higher PD-L1 expression in the spindle components than in the tubular components, but CD4- and CD8-positve T-cells showed greater infiltration in the tubular components than the spindle components.

Combination immunotherapy of nivolumab and ipilimumab may be an effective treatment option for metastatic MTSCC of the kidney.

The use of sternocleidomastoid muscle (SCM) flap for facial reanimation was established in the 1980s by the senior author of this paper. We aimed to analyze long-term outcome and complications of this procedure.

We conducted a retrospective chart review of all patients undergoing SCM reanimation for longstanding facial palsy between January 2009 and December 2015. Patients with follow-up longer than 12 months (range=12-96) were included in the study. Facial muscle function was evaluated before and at each follow-up after the surgery with the House-Brackmann (HB) scale-facial nerve grading system and Facegram analysis. Donor site morbidity and overall complication rates were documented and analyzed.

Forty-two patients aged 18-66 years (mean age=37) with a mean duration of facial palsy of 5 years (range=2-48) met the inclusion criteria. The HB score 2 years after surgery improved significantly (p<0.05) in comparison to the pre-operative condition (3.6 vs. 4.7). Twelve months after surgery, oral commissure excursion improved by mean 8.95 mm. No flap necrosis occurred, nor compromise of neck and shoulder function despite an obvious contour defect in the SCM donor site. None of the patients presented head posture or movement issues.

The SCM flap transfer is a reliable and effective procedure to achieve moderate improvement of the oral commissure excursion using a local method with moderate donor site morbidity. It can be regarded as a valuable option for dynamic facial reanimation in case of longstanding facial palsy.

Multi-parametric magnetic resonance imaging (mpMRI)/ultrasonography fusion prostate biopsy (FB) is a more accurate method of diagnosis than conventional prostate biopsy, but false-positive lesions still exist. Limited studies have examined the cause of false-positive lesions by histological analysis.

We examined 322 patients who underwent mpMRI/transrectal ultrasonography (TRUS) FB. We classified prostate imaging-recording and data system (PI-RADS) 3 and PI-RADS 4-5 as low PI-RADS lesions and high PI-RADS lesions, respectively. In total, 105 lesions were identified as false-positive lesions. We performed histological analysis of atrophy, hyperplasia, and lymphocyte infiltration in these lesions, comparing low PI-RADS lesions and high PI-RADS lesions.

The frequencies of prostate hyperplasia and lymphocyte infiltration were higher in high PI-RADS lesions than in low PI-RADS lesions (p=0.028 and 0.024, respectively). There was no significant difference regarding atrophy (p=0.295).

Histopathological change may be one of the reasons for false-positive lesions.

Recently, hyaluronic acid disc has been known to enhance the success rate of fat myringoplasty. RG-6422 However, hyaluronic acid disc (Epidisc) is not covered by south Korean medical insurance. To date, fat myringoplasty using middle ear packing has rarely been reported. In this study, we studied whether middle ear packing with dexamethasone soaked gelfoam and fibrin glue over the fat graft could promote the success rate of tympanic membrane perforation (TMP) closure without hyaluronic acid disc, regardless of perforation size.

Between January 2005 and July 2020, a total of 209 patients who underwent fat myringoplasty due to chronic TMP at a tertiary referral center were enrolled, and the success rate and audiologic outcomes were analyzed.

The mean successful tympanic membrane (TM) closure rate was 88.0%. The success rate by different age groups showed no significant difference. Further, the size of perforation showed no significant difference, and the perforation site (anterior or posterior) was not significant. The preoperative mean thresholds of air conduction (AC), bone conduction (BC), and air-bone gap (ABG) were 55.71, 12.98, and 42.73 dB respectively. The postoperative mean thresholds of AC, BC, and ABG were 23.67, 12.98, and 10.69 dB, respectively. Change in preoperative and postoperative hearing showed was statistically significant.

Middle ear packing by gelfoam combined with external ear canal packing using fibrin glue enabled stable adhesion between the remnant TM and the fat graft. Regardless of the size of the TMP, the success rate of the fat myringoplasty by our technique can be enhanced without use of hyaluronic acid disc.

We investigated the association of the preoperative lymphocyte-to-C-reactive-protein ratio (LCR) with gastric cancer survival and recurrence after curative treatment.

This study included 480 patients who underwent curative surgery followed by adjuvant treatment for gastric cancer between 2013 and 2017. The prognostic factors for overall survival (OS) and recurrence-free survival (RFS) were identified.

A LCR of 7,000 was regarded as the optimal critical point of classification, considering the 1-, 3- and 5-year survival rates. The OS rates at 3 and 5 years after surgery were 84.4% and 73.9% in the low-LCR group, respectively, and 92.4% and 87.0% in the high-LCR group, respectively, and were statistically significantly different. The RFS rates at 3 and 5 years after surgery were 78.8% and 68.7% in the low-LCR group, respectively, and 89.3% and 86.6% in the high-LCR group, respectively, with a statistically significant difference. A multivariate analysis showed that the LCR was a significant independent prognostic factor for both OS and RFS.

The LCR was a significant prognostic factor for survival in patients who underwent curative treatment for gastric cancer.

It can be difficult to establish the origin of a tumor in metastatic breast cancer (MBC), especially with triple-negative breast cancer (TNBC) or high-grade features. We evaluated the diagnostic utility of GATA3, SOX10, and PAX8 panels in MBC by comparing their expression in each molecular subtype of MBC.

We evaluated 84 MBC and 37 primary TNBC cases using GATA3, SOX10, and PAX8 staining in whole tissue sections.

GATA3 was least sensitive in the detection of metastatic TNBC (metastatic non-TNBC, 0.95; metastatic TNBC, 0.37). SOX10 had the lowest overall sensitivity (0.12) but was elevated in metastatic TNBC, even higher than GATA3 (0.59 vs. 0.37). The combination of GATA3, SOX10, and PAX8 expression showed the highest detection rate (MBC, 0.94; metastatic non-TNBC, 0.95; metastatic TNBC, 0.93).

We recommend combining GATA3, SOX10, PAX8 expression profiling to confirm breast as the site of origin in metastatic MBC.

To assess the dosimetric influence of a semi-cylindrical beam spoiler (sCBS) for the treatment of early glottic cancer using a 6 MV photon beam.

The 2D dose distributions were also calculated and measured with and without the sCBS and with a 0.5 cm thick bolus. A retrospective study of 8 patients treated between 2012 and 2018 was performed.

The 2D dose distributions obtained from the treatment planning system (TPS) and film measurements were in good agreement. In the planning study, the V

, V

, conformal index (CI), and homogeneity index (HI) of all pPTVs for the sCBS plans were better than those for the open field plans (p<0.01). Especially, sCBS plans had better skin sparing effect than bolus plans (p<0.05).

The sCBS of the 6 MV photon beam could be a useful tool for the treatment of early glottic cancers.
