Rhabdomyosarcomas are the most common soft tissue tumors of childhood. They are characterized by their poor prognosis. Vaginal location is very rare after puberty and exceptional in the post menopause. Treatment is based on several therapeutic measures combining neoadjuvant chemotherapy followed by surgery and/or external beam radiation therapy. We report herein the case of a 25 years-old woman, presented with vaginal embryonal RMS revealed by metrorrhagia and pelvic pain. The diagnosis was confirmed by biopsy and histopathological study. Pre-treatment workup was negative for metastatic disease. She has received chemotherapy based on vincristine, doxorubicin, and cyclophosphamide. The clinical evolution was marked by improvement of symptoms, unfortunately the patient died following febrile neutropenia after the third cycle of chemotherapy.
Inferior vena cava (IVC) involvement by intraluminal extension of tumor is infrequent, occuring in 4% to 10% of patients with renal cell carcinoma (RCC) [1-5]. Based on the cephalic extension of the thrombus, Mayo [6] described a classification of inferior vena cava thrombi in 4 categories, which has implications on surgical complexity, estimated blood loss (EBL) and peri-operative complications, but not cancer-specific survival [2,7]. Level III IVC thrombus is classified as being located in the retro-hepatic IVC below the diaphragm. Total resection of this tumor is the best chance of cure when no distant metastases are present [4,8]. Actually, open radical nephrectomy with concomitant thrombectomy is still the standard treatment. This procedure is technically challenging and involves a large incision and prolonged convalescence [9]. Recently, the feasibility of robotic IVC thrombectomy has been demonstrated, with potential lower EBL and shorter hospitalization and convalescence [7,10-14]. This surgery requires thorough knowledge of surgical anatomy, detailed pre-operative preparation and meticulous robotic technique [7]. The key point in the surgical management is the correct assessment of the extension of the endocaval thrombus, what is mainly based on radiological examinations [8]. Although Ultrasonography (US) and computerized tomography (CT) are useful in demonstrating the extent of the thrombus, CT is not always accurate in delineating the superior margin of the tumor in the IVC. More precisely, magnetic resonance imaging (MRI) can demonstrate a tumor thrombus and its extension, besides signs of wall invasion, being extremely useful to surgical procedure planning [8,15]. Vena cavography is not additive to US, CT, and MRI, and it increases the risk of contrast-associated renal injury [4,8]. However, new modern image technologies has emerged to help surgical planning, as three-dimensional visualization technique (3DVT) based on routine CT or MRI processed image data [16-20]. Recently, a comparative study showed advantage of 3DVT in management of complex renal tumor during laparoscopic partial nephrectomy [20]. This modality is able to demonstrate anatomy relations, allowing the surgeon to observe the relationship between targeted tumor and peripheral structure before surgery and perform virtual manipulation. This kind of preoperative accurate assessment can enhance surgeons confidence of surgical procedure and decrease surgical risk and incidence of complications [20]. There is no report in the literature of the use of this type of technology in cases of IVC tumor thrombus.
We present the use of 3D holographic interactive reconstruction in a single case of robotic radical nephrectomy with level III IVC thrombectomy.
The study attempted to answer several questions: Does the cultural and social background of immigrant youth from the Former Soviet Union (FSU) affect their use of addictive substances? Do these youth show distinctive patterns of drug and alcohol abuse? Do the addictive substances used by these teenagers share similar characteristics? Are the patterns of drug abuse and alcohol abuse different? Do students in different educational frameworks demonstrate different consumption patterns? Can “critical moments” explain the presence or absence of alcohol and drug abuse?
The surgical treatment of prostate cancer (PCa) had as its initial milestone the first prostatectomy, performed by H.H. Young at the Johns Hopkins Hospital, in 1904 [1], however, the procedure only reached a fundamental role after 1982, based on a better understanding and description of the male pelvic anatomy, by Walsh [2-6] and other [7-11]. Subsequently, minimally invasive approaches emerged: laparoscopic prostatectomy (1992) [12] and robot- assisted laparoscopic prostatectomy (RALP) (2000) [13], which modified and optimized the execution of key surgical steps of this procedure, such as bladder neck preservation, nerve-sparing dissection, and prostate apex management [14].
Global drug use has reached epidemic levels, with approximately 269 million drug users worldwide [1]. Problematic drug use may lead to serious physical, social, and mental health problems. An estimated 167,000 deaths attributed to drug-related disorders worldwide in 2017 [2]. The rising global drug use and its severe adverse consequences make the drug treatment/rehabilitation a top priority for policymakers. In modern China, illicit drug use has raised great concern from both the academia and the public. Nearly 2.15 million Chinese were registered as drug users in 2019 [28]. Drug-related crimes and deaths are also increasing [29]. The current drug treatment programs in China are mainly compulsory, addressing coercion and discipline. However, the effectiveness was found to be low [3]. Situated in the fields of social work, public health, and psychology, Chinese scholars and practitioners have conducted some empirical tests for these drug treatment/rehabilitation programs and already found several effective preventive factors in the programs. However, the existing research on the design and evaluation of Chinese drug treatment/rehabilitation programs rarely investigate the theoretical rationales behind these programs. This study would address three criminological theories that have been applied to explain drug treatment and rehabilitation in Western societies: Differential Association Theory, Social Bonding Theory, and Labeling Theory. Similar theoretical rationales could be learnt and adopted by Chinese programs.
Background: Epidemiological studies in smokers indicate a dose-response relationship between the number of cigarettes smoked per day and the risk of developing certain smoking related diseases. The alkaloid nicotine is the major pharmacologically active substance in tobacco.
Objective: To estimate the cotinine level excretion in urine among smoked and smokeless tobacco users and nonsmokers among the Indian population.
Materials and methods: The study sample consisted of 250 subjects who were apparently healthy, asymptomatic and not using any drug. The study sample was divided into smoked tobacco users (bidi and cigarette), smokeless tobacco users, both smoked and smokeless tobacco users and controls (non-users of tobacco in the past or present).
Results: The mean Cotinine level in urine was significantly (p – value < 0.05) more among smoked tobacco users in comparison to smokeless tobacco users and non-users of tobacco. Whereas, the mean Cotinine level in urine was significantly (p – value < 0.05) more among smokeless tobacco users in comparison to non-users of tobacco.

Methods: Experimental phase: Performed a partial nephrectomy off clamp in pig model followed by cauterization of lidocaine gel 2% with different power (control, 30W, 50W and 100W) in the kidney resection bed to evaluate efficacy and deep injury extension.
Clinical phase: 20 patients submitted to laparoscopic or partial nephrectomy for low risk RENAL score were utilized greased lidocaine gel 2% with 50W in cautery scalpel to hemostasis of renal parenchima to validate efficacy and safety.
Results: Experimental study shows that this technique is effective and promote better hemostasis with 50W and 100W, with deep injury of less than 3 mm.
Clinical study confirm efficacy, good control of hemorrage, few complications and no transfusion. Minimal changes in hematocrit, haemoglobin and creatinine were observed.
Conclusion: In this preliminary experience the use of this new alternative to hemostasis for low risk partial nephrectomy was satisfactory and with good intra and postoperative results.
The best advantages were safety in terms of the depth thermal injury, low cost and absence of artifacts over the resection area observed at CT scan postoperatively.
The hunger experiment was carried out in 1944 by Anselm Keys and others in the American city of Minnesota. The aim was to investigate the consequences of starvation in order to be able to restore the health of hunger victims of the Second World War. How could they be treated in the best possible way to regain a healthy weight?
For this purpose 36 physical and psychosocial healthy young men were selected from a large group of men who refused to serve in the American Army. They were examined very carefully in the period before the hunger experiment which lasted 6 months. In this period they received only two mails a day with half of the number of calories they were used to eat. This period of malinutrition was followed by 3 months of refeeding. Not only their weight recovered quite well, but also the psychosocial consequences of starvation disappeared completely [1].
Rectourethral fistula (RUF) is a divesting complication after prostate cancer treatment. The RUF incidence after radical prostatectomy is about 0.5% to 2%, [1,2]. Radiotherapy, criotherapy and high intensity focused ultrasound are other more severe causes [3,4].
Repair of RUF is a challenging surgical procedure. There are some possible approaches but transperineal is the most utilized.
In cases of complex fistulas interposition of muscle flaps between the rectum and urethra is highly recommended. Gracilis muscle transposition (GMT) is the preferred, due to excellent mobility and vascularization for perineal reconstruction [5,6]. Dissection of the gracilis muscle is done using one, 2 or 3 large incisions in the medial border of the thigh.
The aim of this report is present a new minimally invasive access to obtain a pediculate flap of gracilis muscle to interposition between bladder and rectum to treat RUF.
Background: the level of alcohol consumption per capita is an important indicator of the alcohol-related problems. However, it is difficult to estimate the real level of alcohol consumption, since part of the consumption comes from illegal sources.
Aim: an overview of studies estimating the overall level of alcohol consumption in Russia.
Methods: in this review, 9 articles were analyzed estimating the overall level of alcohol consumption in Russia.
Results: in the period from 1956 to 2015 the overall level of alcohol consumption was subject to significant fluctuations: it grew almost linearly in the period from 1965 to 1979; decreased markedly in 1981; declined sharply between 1984 and 1987; rose sharply between 1991 and 1994; decreased significantly between 1995 and 1998; then increased significantly in the period from 1999 to 2003, after which it began to decline. The lowest estimate of the level of alcohol consumption for the entire period under consideration was obtained using the method proposed by Razvodovsky (7.25 litres - 1987), and the highest - using the method proposed by Norstrom (19.64 litres - 1994).
Conclusion: despite a significant decrease in the level of alcohol consumption in Russia over the past decade, this level remains high.
