Authors: Arroyo-Kuribreña José Carlos , Ávila-Sánchez Pablo Alejandro , Cuan-Baltazar Yunam , Cano-Herrera Gabriela , Soto-Vega Elena 
Published: February 2022

Case description: A 21-year-old man sought medical attention due to self-insertion of a ballpoint pen into his urethra four months earlier, with incomplete removal. He stated he had difficulty urinating, reduced urinary stream caliber, and needed to strain to urinate. Physical examination revealed a palpable solid object inside the distal urethra. Urethral stricture was ruled out through urethrocystography, and mobility of the foreign body was observed. It was removed through meatoplasty and the “milking” technique. Urethrocystoscopy revealed no associated complications and there were none during the six-month follow-up.
Relevance: Given that there are very few reports on foreign bodies inside the urethra for long periods of time, the present case provides information on the treatment of such patients.
Clinical implications: The insertion of a foreign body into the urethra is uncommon and is generally associated with psychiatric disorders or sexually oriented activity. Intraurethral foreign bodies can be associated with the complications of urethral stricture, infections, urolithiasis, and fistulas, among others.
Conclusions: Diagnosis and treatment were carried out empirically due to lack of evidence in the medical literature, with excellent results.

Introduction: Since its introduction, the TOT sling rapidly became a safe and effective option for the treatment of stress urinary incontinence (SUI) in women. The development of the adjustable TOT sling enabled the tape to be repositioned, in cases with suboptimum results (persistent SUI).
Objectives: To analyze the overall results of our case series, in terms of functional success and postoperative complications, as well as the relation between sling adjustment and the development of postoperative urinary obstruction, mesh erosion, pelvic pain, and dissatisfaction with the tape’s silicone columns.
Materials and Methods: A comparative, retrospective analysis was carried out on patients that underwent adjustable TOT sling placement, within the time frame of 2006 and 2016, assessing a subgroup of patients that had sling repositioning as a second procedure. The variables analyzed were sling adjustment, mesh erosion, complication related to the tape’s silicone columns, development of postoperative urinary obstruction, and functional success of the surgery.
Results: Seventy patients that underwent adjustable TOT sling placement were selected (SUI cured in 84.3%; postoperative obstruction in 22.8%). Slings were repositioned in 11 (15.7%) patients due to adverse functional results, raising the SUI cure rate to 92,8% and the post-adjustment obstruction rate to 28.5%.
There was a significant association between sling adjustment and the development of pelvic pain (36% vs 10%, p=0.02) and no significant differences between groups, regarding the development of postoperative urinary obstruction (p=0.23), erosion into the vagina (p=0.78), erosion into the bladder (p=0.39), and dissatisfaction with the tape’s silicone columns (p=0.9).
Conclusion: The possibility of increasing the functional success of a first surgery, within a few minutes and with local anesthesia, together with the fact that there were no significant differences in the majority of the complications analyzed, make tape adjustment a useful complement in the treatment of SUI, which is not possible with conventional slings.

Clinical case: The present article describes the case of a 48-year-old male patient with no history of interest referred from primary care to evaluate a left perineal tumour occasionally painful. Radiological findings reveal a fatty lesion whose suspected diagnosis is hibernoma being confirmed once the histopathological examination is made.
Relevance: Hibernoma is frequently mistaken for lipoma or liposarcoma due to its clinical and radiological features, being crucial the differentiation to avoid potentially iatrogenic therapies.
Conclusion: Hibernoma is a rare, slow-growing and painless benign neoplasia originated from brown fat. Although it can be suspected according to diagnostic imaging, the definitive diagnosis is histological and the treatment of choice consists of a complete resection. There are no reported cases of recurrence or metastases at the long-term follow-up.

Published: February 2022

Benign prostatic hyperplasia is the most frequent benign tumor in men, reaching a prevalence of 40% in the fourth decade of life and 80% in men 80 years of age and older. The condition leads to bothersome and incapacitating lower urinary tract symptoms that are currently measured by the International Prostate Symptom Score. At present, there are different alternatives for minimally invasive surgical treatment, such as GreenLight laser photoselective vaporization, that can provide the same benefits for the patient as conventional treatment options.
Methods: To find out and describe the usefulness and safety of photoselective vaporization in patients with benign prostatic hyperplasia, a search for information published within the last 10 years was conducted on the PubMed, ScienceDirect, BVS, and ClinicalKey databases, resulting in the selection of 11 notable studies.
Conclusion: GreenLight laser photoselective vaporization is a safe and efficacious alternative for managing the symptoms of benign prostatic hyperplasia, in the short term and long term, with a lower risk of complications than transurethral resection of the prostate.

Published: February 2022

Open radical prostatectomy, since the beginning of the last century has been the gold standard in the localized prostate cancer treatment, and the platform from which minimally invasive procedures such as laparoscopy and robot-assisted surgery have reproduced its results.

Objective: To evaluate the oncological outcomes and functional results of open radical prostatectomy in a cohort of 1420 patients in Mexico City.

Material and methods: A retrospective cohort study of 1420 cases of patients with prostate cancer undergoing radical surgery for a single surgeon (ATG) in private care hospitals.
Results: The median surveillance was 132 months (range 1 to 180 months). Cancer- specific survival was 95% (95% CI 96 to 9), 90% (95% CI 9 to 9), 7% (95%
CI 6 to 9), % (95% CI to 6) and 0% (95% CI 79), at 5, 10 and 15 years respectively. The time free of biochemical progression decreased with greater the risk group, Gleason grade and extraprostatic extension at surgery time.

Conclusion: Radical prostatectomy is up to now a procedure that offers cancer-specific survival as well as survival free of biochemical progression adequate to achieve adequate control of prostate neoplasia.
Off- Clamp nephron sparing minimally invasive surgery for multifocal tumors: experience of a case
Authors: Verdugo-López José Francisco , Arrambide-Herrera José Gustavo , Aviña-Magaña Jaime , Montelongo-Rodríguez Fred Alain 
Published: February 2022

Description of the clinical case: 61-year-old female who presented to the outpatient clinic, asymptomatic and with an imaging study suggestive of multiple ipsilateral right kidney tumors as well as adrenal incidentaloma. The patient was treated with a laparoscopic partial nephrectomy of both renal tumors and adrenalectomy. Renal cell cancer nuclear grade 2 has been reported in the tumor of the upper pole, angiomyolipoma in the middle region of the kidney and cortical adenoma.
Relevance: Until now, the incidence of synchronous renal tumors at the time of diagnosis is unknown, likewise with new technologies and with greater surgeon’s experience, nephron-preserving surgery has been proposed in multifocal renal tumors for the treatment of this type of tumors.
Clinical implications: There is a controversy and few reports where this type of tumors are treated with nephron-sparing surgery in multifocal tumors. So far in series of clinical cases this technique has been reported as safe and feasible in selected cases.
Conclusions: In expert hands and in particular cases, this technique seems to be a reproducible and safe procedure for the patient, thus ensuring that part of the renal unit is preserved, and good oncological results.

Published: February 2022

Objective: To compare the trans and postoperative outcomes (surgical time, intraoperative bleeding volume, and days of hospital stay) in patients undergoing nephrectomy by open approach versus laparoscopic approach.
Material and methods: Retrospective, observational and analytical analysis; We include demographic variables, type of pathology, type of surgical approach and outcomes with descriptive statistics (measures of central tendency and dispersion) and comparative analysis between groups (x2 and Mann-Whitney U test), we consider statistically significant differences when p≤ 0.05.
Results: We analyzed files of 66 women (65.3%) and 35 men (34.7%); 66 (65.3%) had benign pathology and 35 (34.7%) with malignant pathology. Open nephrectomy was performed in 67 (66.3%) patients and laparoscopic nephrectomy in 34 (33.7%) patients. There were no differences regarding gender, age, type of pathology and surgical time. The volume of bleeding and the days of hospital stay were significantly lower in patients with laparoscopic nephrectomy (p = 0.001 and p = 0.041, respectively).
Limitations of the study or implications: Retrospective study.
Originality or value: First report that describes the postsurgical results in nephrectomies performed by open and laparoscopic approach in the south of the country.
Conclusions: Our results are consistent with current evidence regarding the benefits of laparoscopic nephrectomy over open nephrectomy.

Aim: The present study aimed to identify the changes on the bladder mucosa in rats after intravesical infusion of Super-oxidized solution (SOS) (Mycrodacyn60® Mexico).
Design: Eighteen Wistar Albino rats weighing 250-300 g were randomly categorized into three groups. Rats in Group 1 were infused with a single dose of 1.5 ml of 0.9% saline solution (SS) whereas those in group 2 were administered a single dose of 1.5 ml pH neutral SOS. Control rats in Group 3 did not undergo any procedure.
Results: The absence of bacteria was verified before and after the administration of the solution, performing urine cultures and amplifying the 16S rRNA fragment by PCR and histopathological examinations for each bladder. The absence of bacterial DNA in the uroepithelium was demonstrated, histopathological examination revealed, that irrigation with SOS, in histological observation, no structural alterations were identified in the urothelial mucosa.
Limitations: It was not possible to analyze the effect of SOS absorption indamage to the uroepithelium secondary to traumatic infection or injury. The effect of irrigation at different times and volumes with SOS was also not analyzed.
Originality: It is known that SOS is useful as disinfectant in skin and serosa bacterial infections, lacking toxicity and it is effective against Escherichia coli. The use of superoxide solutions in cavities such as the bladder, has not been investigated yet.
Conclusion: The pH-neutral SOS infused transurethral in the bladder of rats has no adverse effects on the uroepithelium, which was supported by histopathological evidence.

Abstract

Objective: To compare oncological and functional results of open and laparoscopic radical prostatectomy in patients with prostate cancer.

Materials and methods: A retrospective cohort analytical study was carried out, where a total of 70 patients with a clinical diagnosis of localized prostate cancer were evaluated, during the period June 2010 to June 2015. The patients were grouped according to the technique used: open surgery (n = 40) and laparoscopic surgery (n = 30). Preoperative variables were analyzed (age, prostate-specific antigen, biopsy histology, functional status and comorbidities), perioperative (surgical time, intraoperative bleeding, hospital stay and complications), postoperative: oncological (stage, histological findings of the surgical specimen and TNM) and postoperative functional (urinary continence and potency or sexual performance).

Results: No significant differences were found in oncological results; but if in intraoperative bleeding (1177 vs 440 cc; p <0.001), hospital stay (5.8 vs 4.6 days; p = 0.003), complications (35 vs 10%; p = 0.016) and continence (65 vs 93%; p = 0.018), in favor of the laparoscopic technique. When evaluating the surgical time, it was found that it was shorter with the open technique (242 vs 295 minutes; p <0.001).

Conclusions: At 60 months of follow-up, there was no significant difference in oncological results or sexual potency between the two groups. With the laparoscopic technique, less intraoperative bleeding, fewer intraoperative and postoperative complications, shorter hospital stay and better recovery from urinary continence were found.

Abstract
Background: The diagnosis of prostate cancer is accomplished with the use of prostatic biopsy. Although the transperineal access has emerged and been used more commonly, the transrectal approach is still the most performed globally. Infectious complications following biopsy are the most important and serious. The use of prophylactic antibiotics is a common practice. Fluoroquinolones have been the most used antibiotics worldwide and remain the first option before prostate biopsy. However, the resistance to these antibiotics has been rising dramatically in the last decades. Resistance shows different numbers in each country and region. The choice of antibiotic will depend on the local sensibilities reported.
Aim: To determine de prevalence of fluoroquinolone and othe antibiotic resistance in patients that come to our hospital for a prostate biopsy. Material and methods: We performed a rectal swab in patients in whom a prostate biopsy was performed. Culture results were obtained and a descriptive analysis of resistance and sensibilities were obtained.
Results: We performed 126 rectal swabs. The main microorganism found in rectal cultures was E.coli. In our study we found a resistance to fluoroquinolones of 83%. The highest sensibility was for carbapenemics. None of our patients developed infectious complications.
Conclusion: We found a resistance rate in rectal flora before prostate biopsy of 83% to fluoroquinolones. We didn´t observe infectious complications in the patients included in our study. The use of antibiotics, bowel preparation, and negative urine culture diminish the possibilities of infectious complications. Although transperineal biopsy offers a minimal risk of infection, patients show more symptoms following this procedure. To our knowledge there are no reports of antibiotic resistance in rectal flora in our population.

Published: February 2022

Introduction: Extracorporeal shock wave lithotripsy (ESWL) is an option for the treatment of urinary lithiasis.
Objective: To describe the outcomes of ESWL for the treatment of urinary lithiasis in children.
Methods: A descriptive and retrospective study of 51 patients with urinary lithiasis that underwent ESWL from 2014 to 2019.
Results: Males and 15–18-year-old patients prevailed; 27.4% had prior surgery; 10-20 mm lithiasis of renal location and density between 400-799 HU were the most common; a double J stent was the most utilized urinary derivation prior to lithotripsy treatment; 7.8% required retreatment; 13.7% additional interventions; the stone-free rate was 74.5% at one month and 92.2% at three months. The size of the lithiasis was associated with the success of the treatment (p<0.023). The most frequent complication was steinstrasse; endourologic procedures were the most utilized, grade III b (Clavien-Dindo) prevailed and were associated to older patients (p=0.04), renal lithiasis localization (p=0.017), larger size (p=0.08), and density(p=0.036).
Conclusions: ESWL is effective and safe for treating urinary lithiasis in children. Its success was significantly associated to smaller stone size and its complications to patients of older age, larger stone size, density and renal localization of the lithiasis.
ACTIVIDAD ANTIBACTERIANA Y CITOTOXICIDAD DE CINCO ESPECIES VEGETALES DE LA ZONA ALTOANDINA Y AMAZÓNICA DE LA REGIÓN DEL CUSCO
Authors: CARDONA RIVERO ANAHI KARINA 
Published: February 2022

La presente investigación, tuvo como objetivo evaluar la actividad antibacteriana y citotoxicidad de cinco especies vegetales de la zona altoandina y amazónica de la región del Cusco. Se desarrolló una investigación descriptiva, no experimental y transversal. Se realizaron estudios preliminares que consistieron en el tamizaje fitoquímico cualitativo y análisis espectrofotométrico UV-Vis de las especies Acicarpha tribuloides Jussieu (Estrella Kisca), Gamochaeta spicata (Queto-Queto), Minthostachys glabrescens (Bentham) Epling (Muña), Muehlenbeckia volcanica (Bentham) Endlicher (Mullaca) y Piper elongatum M. Vahl (Matico). Las muestras fueron recolectadas en diferentes provincias y distritos de la región del Cusco. La identificación taxonómica se realizó en el Herbario Vargas CUZ de la Universidad nacional de San Antonio Abad del Cusco. Los extractos etanólicos de las cinco especies se obtuvieron mediante el método de maceración. El tamizaje fitoquímico cualitativo de los extractos se efectuó a través de reacciones de coloración y precipitación (Rondina y Coussio, 1969 modificado por Alfonso et al., 2000). También, se realizó el análisis espectrofotométrico Uv-vis de los extractos. En el caso de la actividad antibacteriana, se determinó la concentración mínima inhibitoria (CMI), empleándose el método de macro dilución en medio líquido (Granados R. y Villaverde C., 1997; Woods G y Washington J. 1995) y cepas ATCC de Escherichia coli 25922, Staphylococcus aureus 29213, Streptococcus pneumoniae 49619 y Salmonella typhimurium 14028. Asimismo, para determinar el grado de toxicidad de los extractos se utilizó el ensayo de Artemia salina (CYTED, 1995). Los resultados obtenidos en el análisis fitoquímico cualitativo y espectrofotométrico UV-Vis, muestran que las plantas investigadas contienen compuestos fenólicos, flavonoides, taninos y saponinas en mayores cantidades. Por otro lado, con respecto a la actividad antibacteriana, el Queto-Queto y la Mullaca tienen efecto frente a Staphylococcus aureus, Escherichia coli y Streptococos pneumoniae; Mientras que, el Matico actúa frente Streptococos pneumoniae y Staphylococcus aureus. En el caso de la Estrella Kisca y Muña dieron positivo frente a
Salmonella typhimurium y Escherichia coli. La prueba de citotoxicidad con Artemia salina, demostró que, los extractos de Estrella Kisca y Queto – Queto son muy tóxicos con una CL50 de 19.639 y 58.104 respectivamente. Por otro lado, los extractos considerados moderadamente tóxicos son los de Muña, Mullaca y Matico con CL50 de 100.092, 415.451 y 158.006 respectivamente.

A cash flow statement is a financial report that contains information on cash inflows and cash outflows from a company during a certain period. This information is presented according to the type of activity that causes the cash inflows and outflows to occur. Company activities generally consist of three types, namely, operational activities, investment activities and financial activities.
The process of receiving and disbursing cash is also recorded at any time for the preparation of the company's income statement. Cash flow recording activities at this company are still manual where every company receipt will be recorded by employees of the finance department which will ultimately be recapitulated in the annual report and compared with other recording results such as cash disbursements.
This system has many weaknesses where the information needed cannot be presented quickly and accurately, requiring a fairly complicated process for a longer time to check certain cash flows.
