INTRODUCTION
Only few reports are known about the use of robotic surgery for prostate benign enlargement. The robotic surgery can be improved by laparoscopic tricks. We show a video of robotic adenomectomy where a laparoscopic dissector is used to help create the plan between prostatic capsule and adenoma.
MATERIALS AND METHODS
A 62 years old male had severe urinary flow outlet obstruction. Medical therapy was not effective. Ultrasound detected a 92gr enlarged prostate with a large middle lobe. Robotic assisted adenomectomy was scheduled. The procedure followed this sequence: opening of Retzius space, superficial suture of the Dorsal vein complex, horizontal cistotomy. The plan was created with electrocautery and blunt dissection with the laparoscopic dissector. Haemostatic sutures were placed between prostate fossa and the posterior bladder neck and closure of the cistotomy.
RESULTS
Whole operation time was 160 minutes, with a blood loss of 80cc. There was no perioperative or post-operative complication. Catheter was removed after 4 days. Post-operatory uroflowmetry shows a peak flow of 30ml/sec. Pathological examination is negative for tumor. After 60 days IPSS was 8.
CONCLUSION
Robotic prostate adenomectomy using the laparoscopic dissector is a safe and effective minimally invasive treatment for benign prostatic enlargement. It is a novel technique to find and dissect the plane between prostatic adenoma and capsule. This could be one more use of laparoscopic technology to improve surgical outcomes in robotic field.

BACKGROUND
The number of studies and clinical interest in the anterolateral ligament of the knee (ALL) has grown in recent years. A meticulous and accurate ALL dissection is vital in anatomic and biomechanical studies, and a standardized technique is not yet established. As such, the aim of this study was to describe a step-by-step ALL dissection technique that could help authors consistently identify the ALL.
METHODS
Twenty knees from frozen adult cadavers, with no preference for sex or age, were included in the study. All the cadavers were dissected using the same technique to determine the incidence of the ALL.
RESULTS
A transverse incision is performed in the iliotibial band (ITB), around 10 cm proximal to the topography of the lateral epicondyle of the femur. Next, the ITB undergoes anterograde blunt dissection until its insertion at Gerdy's tubercle in the tibia. Maintaining biceps femoris insertion, a dissection is performed anteriorly to it, until the lateral collateral ligament (LCL) is found. Using the LCL, internal rotation and 30 to 60° flexion as references, the ALL can be located in the anterolateral topography of the knee, with its origin near the lateral epicondyle (proximal and posterior) and insertion between Gerdy's tubercle and the fibula (4.0 mm to 7.0 mm below the tibial plateau), expanding to the lateral meniscus (between the body and anterior horn), exhibiting a mean length of 4.0 ± 0.4 cm and mean width of 5.5 ± 0.8 mm.
CONCLUSIONS
The present article describes an effective and reproducible ALL dissection technique that made it was possible to identify the ligament in 100% of the cases in the present study.

OBJECTIVES
This qualitative study aims to explore how fourth-year medical students on the surgery course perceived a clinical anatomy workshop organised by near-peer student teachers in partnership with faculty.
METHODS
Forty-seven medical students participated in a workshop on clinical anatomy in the dissection laboratory. A voluntary response sampling method was used. The students' perceptions of the workshop were explored through a thematic content analysis of transcribed, semi-structured group interviews and written comments.
RESULTS
A majority of the students had not revisited the dissection laboratory since their second year, and all students described the workshop as a unique opportunity to vertically integrate anatomical knowledge. Four main themes were identified as most valuable for the students' learning experience, namely that the workshop 1) was taught by knowledgeable and friendly near-peer tutors (NPTs), 2) consisted of highly relevant anatomical content, 3) offered a hands-on experience of cadavers in the dissection laboratory, and 4) was taught in a focused session in the middle of the surgery course.
CONCLUSIONS
This study shows how hands-on workshops in clinical anatomy, developed in student-staff partnerships and taught by NPTs, can enable senior medical students to recall and vertically integrate anatomical knowledge during surgical clerkships. The results have implications for curriculum design, giving voice to senior students' wishes for spaced repetition and vertical integration of pre-clinical anatomy knowledge during their clinical training. Moreover, this study may inspire other students and faculty to develop similar near-peer teaching activities through student-staff partnerships.

The lacrimal gland (LG) secretes aqueous tears necessary for maintaining the structure and function of the cornea, a transparent tissue essential for vision. In the human a single LG resides in the orbit above the lateral end of each eye delivering tears to the ocular surface through 3 - 5 ducts. The mouse has three pairs of major ocular glands, the most studied of which is the exorbital lacrimal gland (LG) located anterior and ventral to the ear. Similar to other glandular organs, the LG develops through the process of epithelial branching morphogenesis in which a single epithelial bud within a condensed mesenchyme undergoes multiple rounds of bud and duct formation to form an intricate interconnected network of secretory acini and ducts. This elaborate process has been well documented in many other epithelial organs such as the pancreas and salivary gland. However, the LG has been much less explored and the mechanisms controlling morphogenesis are poorly understood. We suspect that this under-representation as a model system is a consequence of the difficulties associated with finding, dissecting and culturing the LG. Thus, here we describe dissection techniques for harvesting embryonic and post-natal LG and methods for ex vivo culture of the tissue.

INTRODUCTION
Anatomy is an important and intense mandatory course offered during the first year of medical school. Corpse dissection is very important in Anatomy teaching, and first year students will encounter, most likely for the first time, a dead human body during Anatomy labs.
OBJECTIVES
The purpose of this study was to evaluate the anxiety experienced by medical students with no previous corpse dissection background just before, after a week, and then after a month of dissection labs, and to investigate the relationship between students' personality and their attitude towards dissection.
SUBJECTS AND METHODS
138 first year English Section medical students from the "Iuliu Hatieganu" University of Medicine and Pharmacy, Cluj-Napoca, Romania, completed a personality inventory, an anxiety scale and a questionnaire to assess their attitudes and reactions to anatomical dissection.
RESULTS
The level of anxiety reported by students increased from before the first dissection encounter to after one month of dissection labs.
CONCLUSIONS
There is a relationship between the Five Factor model of personality and students' attitudes towards dissection. Medical students could be better prepared for their first corpse dissection experience if the preparation before dissection would take in consideration their psychological traits.

Spontaneous multiple arterial dissection (SMAD) is a rarely reported phenomenon and has been previously linked to connective tissue diseases and specifically the genetic mutations in SMAD3 and COL3A1. Herein we describe a case of SMAD with scattered thrombi in a COVID-19-positive patient with a history of unspecified mitochondrial myopathy. Vasculopathy involved the splenic artery, inferior mesenteric artery, internal mammary arteries, omental arteries, mesenteric arteries, and small renal arteries. Dissections were confirmed by histology in the splenic artery, inferior mesenteric artery, and bilateral renal medullary arteries. Genetic studies were done to rule out SMAD3 and COL3A1 mutations. Because the Smad3 protein has been previously implicated in COVID-19-associated tissue fibrosis, it may play a role in endothelial dysfunction as well.

Tick-borne viruses cause thousands of cases of disease worldwide every year. Specific countermeasures to many tick-borne viruses are not commercially available. Very little is known regarding tick-virus interactions and increasing this knowledge can lead to potential targets for countermeasure development. Virus infection of ex vivo organ cultures from ticks can provide an approach to identify susceptible cell types of tissue to infection. Additionally, these organ cultures can be used for functional genomic studies to pinpoint tick-specific genes involved in the virus lifecycle. Provided here are step-by-step procedures to set up basic tick organ cultures in combination with virus infection and/or functional genomic studies. These procedures can be adapted for future use to characterize other tick-borne pathogen infections as well as tick-specific biological processes. © 2020 Wiley Periodicals LLC.

BACKGROUND
It has been well reported that the emotional experiences of medical students in the gross anatomy laboratory could have significant impacts on their professional identity formation. This qualitative study aimed to investigate students' emotions towards cadaver dissection and the educational role of memorial ceremonies.
METHODS
A total of 37 students from eight teams were recruited in the team-based dissection course during two consecutive academic years (2016 and 2017) at one medical school. In focus group interviews, students were encouraged to express and discuss their emotions regarding cadaver dissection and memorial ceremonies.
RESULTS
The participants described their apprehension and anxiety during their first encounter with cadavers that diminished through gradual exposure. Unfortunately, their positive emotions such as gratitude and responsibility also tended to decline under the pressure of excessive workloads and frequent examinations. Memorial ceremonies, including not only large-scale events but also daily rituals, had educational effects that they prevented the decline of students' responsibility and respect during the dissection course.
CONCLUSION
Educators should assist medical students in overcoming their initial distress and maintaining respectful attitudes throughout the dissection course. Memorial ceremonies can be effective educational tools for fostering appropriate attitudes and ethical practice in the gross anatomy laboratory.
