A rare case of leiomyoma of the bladder
Full text linkBladder leiomyoma is a benign tumour of the bladder and constitute <0.5% of all bladder tumors. We report a clinical case of a 51‐year‐old female who presented with with symptomatic bladder leiomyoma. An ultrasound examination showed well-defined bladder leiomyoma in the right posterior bladder wall, which was excised through a transurethral resection. The pathologic diagnosis was bladder leiomyoma
Robot-Assisted Liver Resection and Cholecystectomy Using Indocyanine-Green for Intrahepatic Cholangiocarcinoma, in a Very Rare Anatomical Anomaly of ‘Bipartite Liver’
No full textRobotic hepatobiliary surgery has significantly developed worldwide with substantial clinical results. Hepatobiliary anatomical anomalies increase the complexity of hepatobiliary resection with a relevant risk of iatrogenic lesions. Among congenital liver anomalies, the ‘bipartite liver’ is an extremely rare condition which might be associated with complex surgical dissection of the hepatic hilum. We herein report a rare case of congenital ‘bipartite liver’ associated with a cholangiocarcinoma of segment VI and calculous cholecystitis. The patient underwent robot-assisted segmentectomy and cholecystectomy with the use of indocyanine-green cholangiography and intraoperative ultrasound. A challenging hilar dissection was performed using this approach. To the best of our knowledge, this is the first case reported that describes a robot-assisted liver resection and cholecystectomy in a patient having a cholangiocarcinoma associated with this rare liver anomaly. The robotic approach was safe and effective and the 3D preoperative imaging, as well as the intraoperative green-indocyanine cholangiography was extremely useful, especially during hilar dissection and cholecystectomy

Robotic surgery for colorectal liver metastases resection: a systematic review
Full text linkBackground: The role of robotic surgery for colorectal cancer liver metastases (CRCLMs) has never been investigated in large series. Methods: A systematic literature review was carried out on PubMed and Cochrane libraries. Results: We selected nine studies between 2008 and 2021. Two hundred sixty-two patients were included. One hundred thirty-one patients underwent simultaneous resections. The mean blood loss was 309.4 ml (range, 200-450 ml), the mean operative time was 250.5 min (range, 198.5-449.0 min). The mean length of hospital stay was 7.98 days (range, 4.5 to 12 days). The overall postoperative mortality was 0.4%. The overall morbidity rate was 37.0%, Clavien-Dindo grade III-IV complications were 8.4%. The mean 3-year overall survival was 55.25% (range, 44.4-66.1%), the mean 3-year disease free survival was 37% (range, 33.3-41.9%). Conclusion: We can conclude that robotic-assisted surgery might be considered as a technical upgrade option for minimally invasive approach to CRCLM resections even for simultaneous operations and challenging cases
Open and / or laparoscopic surgical treatment of liver hydatic cysts
Full text linkHydatid disease is a severe parasitic disease with a widely ranging distribution. In the human being the liver is the most frequent organ affected. 1 The treatment should be individualized to the morphology, size, number and location of the cysts, that is why a variety of surgical operations have been advocated from complete resection like total pericystectomy or partial hepatectomy to laparoscopy to a minimally invasive procedures like percutaneous aspiration of cysts to conservative drug therapy. 3-4 This study compares laparoscopic versus open management of the hydatid cyst of liver the surgical approach to liver echinococcosis is still a controversial issue and shows our results of surgical treatment of liver hydatid cysts during a 3-years period
A rare case of lipoma arising from pterygopalatine fossa (PPF). Radiological diagnostic imaging with 3D CT cone beam
Full text linkLipomas of the oral cavity are infrequent, representing about 0.5% to 5.0% of all benign oral tumors. Some lipomas are reported in paranasal sinuses diseases. We report an extremely rare case of infiltrating lipoma arising from pterygopalatine fossa studied with 3D cone beam, HRCT and MR imaging
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Groin hernia containing bladder diverticula. Report of two cases and review of the literature
No full textUna parte della vescica urinaria è coinvolta in ernie inguinali in circa il 10% dei casi (1); tuttavia, i diverticoli vescicali sono raramente coinvolti, passando dallo 0,36% all'1-3% delle ernie inguinali (2,3). I pazienti possono lamentarsi di vari sintomi, che vanno dal tumore all'inguine alla compromissione urologica; la diagnosi differenziale deve essere fatta principalmente con una comune ernia dell'inguine. L'obesità con rilassamento muscolare, la dilatazione vescicale conseguente ad ipertrofia prostatica (4), o la perdita di tono vescicale per danno neurologico (5) rappresentano i principali fattori favorevoli alla comparsa dei diverticoli vescicali. Complicazioni come calcoli vescicali, infezioni, sviluppo di tumori (6) all'interno dei diverticoli, o idronefrosi, sono ancora più rare. Sono necessari un'anamnesi corretta, un attento esame fisico e un corretto schema diagnostico, incluse la cistografia, la TAC e le scansioni negli Stati Uniti (5). L'intervento chirurgico è consigliato quando compaiono sintomi specifici o se il cancro uroteliale cresce all'interno di un diverticolo (7). Segnaliamo due casi di erniazione inguinale dei diverticoli vescicali con diversa presentazione clinica ed evoluzione; vengono anche mostrate scansioni TC che evidenziano la malattia.A portion of the urinary bladder is involved in groin hernias in about 10% of cases (1); anyway, bladder diverticula are rarely involved, being found from 0.36% to 1-3% of groin hernias (2,3). Patients can complain of various symptoms, ranging from groin tumour to urologic impairment; differential diagnosis is to be made mainly with a common groin hernia. Obesity with muscle relaxation, bladder dilation consequent to prostatic hypertrophy (4), or loss of bladder’s tone due to neurological damage (5) represent the main favoring factors for the occurrence of bladder diverticula. Complications such as bladder stones, infections, cancer development (6) within diverticula, or hydronephrosis, are even rarer. A correct anamnesis, a careful physical examination and a correct diagnostic pattern, including cystography, CT and US scans, are needed (5). Surgery is recommended when specific symptoms appear, or if urothelial cancer grows within a diverticulum (7). We report two cases of groin herniation of bladder diverticula with different clinical presentation and evolution; CT scans evidencing the disease are shown as well
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
