Positive urine culture prior to transrectal prostate biopsy was not associated with infectious complications development.

OBJECTIVE: Prostate cancer is one of the most common cancers worldwide. Its histological diagnosis is based on prostate biopsy. The transrectal procedure is one of the most common procedures performed by urologists. Although it is considered safe, post-biopsy infectious complications are frequently observed in practice. The aim of this study is to investigate the value of urine culture before the transrectal biopsy. Secondly, we assessed potential risk factors for infectious complications following TR-PB. METHODS: We performed a retrospective analysis of all patients who underwent urine culture tests before transrectal prostate biopsy between January 2019 and July 2020. The inclusion criteria for the study were all indications for prostate biopsy (PSA>4ng/mL or abnormal digital rectal examination). Baseline characteristics and the incidence of post-biopsy urinary tract infection were compared between patients showing positive pre-biopsy culture results and those showing negative findings. Multivariate logistic regression analyses were used to determine risk factors for infectious complications following TR-PB. RESULTS: Out of 163 patients included in our study, 19 patients (11.65%) had positive urine culture results before the biopsy. Age (P=0.068); history of hospitalization (P>0.999), history previous of quinolone use (P=0.75), history of UTI (P=0.64); median PSA level at diagnosis (P=0.267); prostate volume (P=0.78); post-void residual volume (P=0.374); percentage of patients testing positive for cancer on biopsy (P=0.81); and percentages of patients with a history of biopsy (P=0.889), diabetes mellitus (P=0.524), hypertension (P=0.714) and immunosuppressive medication use (P>0.999) were similar between the two groups. One patient in the positive urine culture group had post-biopsy prostatitis. However, 3.24% (five patients) of the negative urine culture group had the disease (P=0.789) (four patients with prostatitis and one with epididymitis). Among them, four patients were diagnosed by urine culture at the time of post-biopsy urinary tract infection. Multivariate logistic regression analysis demonstrated that history of hospitalization and history of previous quinolone use were risk factors for infection after transrectal prostate biopsy. CONCLUSION: Our study suggests that systematically performing urine cultures before transrectal prostate biopsy does not reduce the rate of infectious complications after biopsy. Positive pre-biopsy cultures were not associated with the development of post-biopsy infectious complications.

Metachronous isolated locally advanced pancreatic metastasis from chromophobe renal cell carcinoma.

INTRODUCTION: Metastasis to the pancreas is relatively uncommon occurrence. Isolated pancreatic metastasis from renal cell carcinoma (RCC) is relatively rare and it's usually seen in clear cell renal cell carcinoma (CCRCC), but its occurrence from chromophobe renal cell carcinoma (chRCC) is extremely rare, due to its relatively low-grade metastatic potential. PRESENTATION OF CASE: The authors report an unusual case of metachronous isolated pancreatic metastasis, in a 65-year-old female patient two years after left nephrectomy for chRCC, diagnosed during routine surveillance imaging and confirmed after a CT-guided pancreatic biopsy. DISCUSSION: The pancreas is an elective site for metastases from RCC, and this particularity has been reported by several studies, but only described for CCRCC. In the English literature there is only one case of pancreatic metastasis from chRCC diagnosed in an autopsy study. Surgical resection of metastasis remains the most effective treatment, particularly for pancreatic metastases from chRCC, since radiotherapy, chemotherapy, hormonal therapy, and targeted therapy have generally proved ineffective for metastatic chRCC. In case of an unresectable disease, surgical or endoscopic palliation in association with palliative chemotherapy can improve the quality of life but not survival. CONCLUSION: This case highlights the unique behavior of chRCC with an unusual site of metastasis, and the necessity of long-term follow-up after primary tumor removal, even if it is known for a low-grade metastatic potential and a relatively good prognosis.

[Do the nephrolithometry scoring systems predict the success of percutaneous nephrolithotomy. Comparison of 4 scores: The Guy's stone score, STONE Score, CROES nomogram and S-ReSC score]. / Les scores radiologiques peuvent-t-ils prédire le succès de la NLPC ? Étude comparative du Guy's stone score, du STONE score, du CROES nomogram, et du S-ReSc score.

INTRODUCTION: The aim of the study is to investigate the factors predictive of surgical outcomes of PCNL and to compare the predictability and accuracy of the Guy's stone score, STONE nephrolithometry, CROES nomogram and S-ReSC score. PATIENTS AND METHODS: We reviewed retrospectively the surgical outcomes recorded consecutively and imaging data of preoperative computed tomography scans of patients who underwent PCNL from 2013 to 2016. Patients with asymptomatic residual fragments<4mm were considered stone-free. Preoperative abdominopelvic computerized tomography images of the patients were reviewed and scored according The Guy's stone score, STONE nephrolithometry, CROES nomogram, S-ReSC score by one urologist. RESULTS: A total of 157 PCNLs were reviewed. The overall stone-free rate was 59% (92/157) with a complication rate of 22% (35/157). Stone Burden<542mm3 is significantly associated with stone-free rate (SFR) (P=0.001). On univariate analysis, all the scoring systems were identified as significant factors in terms of SFR. The Guy's Stone Score, the CROES score and the S-ReSC score were associated with complications (P<0.02). The multivariate logistic regression analysis showed that the CROES score was identified as a significant factor in terms of SFR and complications (P<0.01). The area under the receiver operating characteristic (ROC) curves for stone burden, the Guy's, STONE score, CROES core and S-ReSC scores showed good results (0.737/0.674/0.762/0.746/0.710) respectively. CONCLUSION: Although the four scoring systems were significantly associated with SFR, the STONE score was a significant predictive factor for SFR and complications after PCNL. LEVEL OF EVIDENCE: 3.

Malignant rhabdoid tumor in a solitary kidney arising in an adult patient with chronic obstructive renal calculi.

INTRODUCTION: Malignant rhabdoid tumor (MRT) is one of the most aggressive and lethal malignancies in pediatric oncology, MRT of the kidney is an uncommon renal tumor in children and it's extremely rare in adult patients. With only seven previously reported adult cases in the English-literature, to our knowledge this is the first case that is associated with renal calculi. PRESENTATION OF CASE: We present the case of a 65-year-old man with an MRT arising in a solitary kidney with multiple enlarged lymph nodes that compressing the inferior vena cava. DISCUSSION: Malignant rhabdoid tumor of the kidney was originally described as a "rhabdomyosarcomatoid" variant of Wilm's tumor due to the resemblance of cells to rhabdomyoblasts, now this type of tumor is recognized as distant and unique malignant renal tumor. It affects usually children before the age of 2 years. Tumor tissue sampling is required to make the diagnosis of MRTK, based on either nephrectomy, core biopsy, or autopsy specimens. There is no established standard of care due to the paucity of cases. Surgery is considered to be the first choice of treatment if possible. CONCLUSION: This case report reinforces the importance of recognizing this entity in the adult population, and discuss the possible treatment options of this rare and highly aggressive tumor.

Retroperitoneal extra-adrenal non-Hodgkin lymphoma: An uncommon presentation.

Primary retroperitoneal non Hodgkin lymphoma is extremely rare, its diagnosis is often difficult and it may requires a time consuming and a costly diagnostic workup. We report the case of a 46-year-old patient complaining of abdominal fullness and dorsal pain, who was diagnosed with an extra-nodal non-Hodgkin lymphoma presenting as a unique and large retroperitoneal mass. The suggested diagnosis was a malignant retroperitoneal tumor and the patient underwent an excision of the tumor throw a lombotomy followed by an R-CHOP chemotherapy regimen with good outcome.

[Mini-invasive posterior sacrospinous ligament fixation using the CAPIO needle driver: an anatomical study]. / Sacrospinofixation mini-invasive avec le dispositif CAPIO : étude anatomique.

OBJECTIVE: To study anatomical risks after posterior sacrospinous ligament fixation using the CAPIO needle driver. SUBJECTS AND METHODS: A simplified bilateral posterior sacrospinous ligament fixation was performed on seven fresh female cadavers using the CAPIO needle driver. Cadavers were installed in gynaecologic position then dissected by the abdominal route. The posterior sacrospinous ligament fixation was performed after a posterior vaginal wall incision on the midline and a simplified dissection of both pararectal fossae. The abdominal dissection was focused on the sacrospinous ligament area. We measured the distance between the neurovascular elements adjacent to the sacrospinous ligament from the suture site. RESULTS: Thirteen sacrospinous ligaments were available for analysis. The mean length (+/-SD) of the ligament was 51+/-9.2 mm and the mean width at the level of fixation (+/-SD) was 23.5+/-5.7 mm. No rectal injury was observed. Fixations were in the deeper (ligament) and medium (muscle) part of the SSL in eight (61%) and five (39%) cases respectively. The ischial spine was 21.6 mm (range: 13-30). The mean distances between fixation and pudendal nerve and artery were 16.1 mm (range: 4-32) and 20 mm (range: 12-37) respectively. CONCLUSION: Mini-invasive posterior sacrospinous ligament fixation using the CAPIO needle driver seemed to be reproducible with low anatomical risks. However, the fixation should be at least at 20 mm medially to the ischial spine in order to reduce neurological risks.

[Systemic manifestations of chronic hepatitis C]. / Les manifestations systemiques des hépatites virales C chroniques.

It's well known that hepatitis C virus (HCV) related chronic liver disease may be associated with various extra hepatic disorders. These manifestations can revealed the hepatic disease. We review the available data on the conditions and asses their clinical implications: vascular, cutaneous, articular, neurological or renal disorders. There is no correlation between these extra hepatic manifestations and the severity of liver disease. Several recent studies have established a strong link between HCV infection and essential mixed cryoglobulinemia but some other extra hepatic associations are just fortuitous. Others datas are necessary to better analyze these extra hepatic disorders and to offer the beneficial treatment of patients with chronic hepatitis C.

[Cystic cervicofacial lymphangioma]. / Lymphangiomes kystiques cervico-faciaux.

A review of fifteen new cases of cystic cervicofacial lymphangiomas is presented. While discussing the different localizations of these malformations, the authors emphasize the relationships existing between this type of malformation and both the facial nerve and the vasculonervous axis of the neck. They recommend surgical management. 1-to-10 years' follow-up revealed one case of local recurrence associated with incomplete excision.

[Atypical metastases disclosing vesicular carcinoma of the thyroid]. / Métastases atypiques révélatrices des carcinomes vésiculaires de la thyroïde.

Differentiated carcinoma of the thyroid may generate bone or lung metastases. Some times, thyroid cancer remains latent, and is revealed by the presence of secondary bone tumors. In the present paper, we relate our personal experiences with two patients who had thyroid cancer diagnosed indirectly through the occurrence of distant metastases. The secondary tumors were localized in the right frontal sinus and the cranial vault, respectively. We discuss the diagnostic and therapeutic problems involved with such metastases. We further present a review of the literature dealing with this topic.

[Adenoid cystic carcinoma in the head and neck. A retrospective study of 12 cases]. / Les carcinomes adénoïdes kystiques à localisation cervico-faciale. Etude rétrospective de douze cas.

Basing themselves on a series of twelve cases of cervicofacial cylindromas, the authors review the different clinical data pertaining to the evolution of these tumors, which they find to be prevalent in females aged around sixty. Cylindromas predominantly occur in the submandibular and accessory salivary glands. Out of twelve cases, the report mentions three local recurrences and two pulmonary metastases. Management was surgical in all instances.
