RESUMEN

BACKGROUND: Azoxymethane (AOM) is a potent carcinogenic agent commonly used to induce colon cancer in rats; the cytotoxicity of AOM is considered to mediate oxidative stress. This study investigated the chemopreventive effect of three natural extracts [pomegranate peel extract (PomPE), papaya peel extract (PapPE) and seaweed extract (SE)] against AOM-induced oxidative stress and carcinogenesis in rat colon. METHODS: Eighty Sprague-Dawley rats (aged 4 weeks) were randomly divided into 8 groups (10 rats/group). Control group was fed a basal diet; AOM-treated group was fed a basal diet and received AOM intraperitonial injections for two weeks at a dose of 15 mg/kg bodyweight, whereas the other six groups were received oral supplementation of PomPE, PapPE or SE, in the presence or absence of AOM injection. All animals were continuously fed ad-libitum until aged 16 weeks, then all rats were sacrificed and the colon tissues were examined microscopically for pathological changes and aberrant crypt foci (ACF) development, genotoxicity (induced micronuclei (MN) cells enumeration), and glutathione and lipid peroxidation. RESULTS: Our results showed that AOM-induced ACF development and pathological changes in the colonic mucosal tissues, increased bone marrow MN cells and oxidative stress (glutathione depletion, lipid peroxidation) in rat colonic cells. The concomitant treatment of AOM with PomPE, PapPE or SE significantly ameliorated the cytotoxic effects of AOM. CONCLUSIONS: The results of this study provide in-vivo evidence that PomPE, PapPE and SE reduced the AOM-induced colon cancer in rats, through their potent anti-oxidant activities.

RESUMEN

Antimicrobial peptides (AMPs) are multifunctional components of the innate immune system. Chemotherapeutic agents used for treatment of visceral leishmaniasis (VL) are now threatened due to the emergence of acquired drug resistance and toxicity. AMPs are attractive alternative to conventional pharmaceuticals. In this study, first time we explored the antileishmanial activity of spinigerin originally derived from Pseudacanthotermes spiniger. Leishmania donovani promastigotes present apoptosis-like cell death upon exposure to spinigerin (IC50, 150 µM). The infection rate was reduced by 20% upon exposure to 150 µM spinigerin but no cytotoxicity on host macrophages was observed. Elevation of intracellular ROS level and down-regulation of two ROS detoxifying enzymes, ascorbate peroxidase (APx) and trypanothione reductase (TR) suggested essential role of ROS machinery during spinigerin mediated cell death. About 97% cell population was found to be Annexin-V positive; 44% cells being highly Annexin-V positive. Moreover, we observed morphological changes like cell rounding, nuclear condensation, oligonucleosomal DNA degradation and TUNEL positive cells without loss of membrane integrity upon spinigerin exposure, suggests apoptosis-like death. Interestingly, collapse in mitochondrial membrane potential and increased level of intracellular ROS and calcium were not associated with caspase like activity. Computational analysis suggests spiningerin interacts with trypanothione reductase and thus probably interferes its function to detoxify the toxic ROS level. Therefore, spinigerin induces apoptosis-like cell death in L. donovani in a caspase-independent manner. The study elucidates the antileishmanial property of spinigerin that may be considered for future chemotherapeutic option alone or adjunct with other drug regimens for improved treatment of visceral leishmaniasis.

RESUMEN

Nosocomial infection is a major challenge for the appropriate management of burns. The present study aimed to investigate incidence, risk factors, and causative organisms of nosocomial infection in burn patients of Khulna, Bangladesh. This cross-sectional study was conducted among patients admitted to the Burn and Plastic Surgery Department of Khulna Medical College Hospital (KMCH) from January to December 2020. Relevant data were collected from the patients' hospital records. Samples of wound swabs and blood were collected and cultured in the microbiology laboratory of KMCH. Logistic regression models were used to determine risk factors for infective complications in burn patients. All statistical analyses were carried out using SPSS version 26.0. A total of 100 burn patients were included. Mean age was 29.2 years with a male-female ratio of 1.3:1. Flame burns were most prevalent among the patients (41%), followed by scald (23%) and electric burns (15%). Almost 40% patients had full thickness burn. The incidence of nosocomial infection was 42% (wound infection 33% and septicemia 9%). Total body surface area of burn >40% (OR 7.56, 95% CI 2.89-19.81), full thickness burn (OR 34.40, 95% CI 3.25-97.14) and prolonged hospital stay (aOR 1.31, 95% CI 1.15-1.51) were significant risk factors for nosocomial infection. Staphylococcus aureus was the most commonly isolated organism (45%), followed by Streptococcus (24%), Pseudomonas aeruginosa (19%) and Escherichia coli (12%). As the epidemiology of nosocomial infection is not the same in different health facilities, a facility-based comprehensive burn management protocol considering the local epidemiology and causative organisms of burn wound infection is crucial for the prevention and management of nosocomial infections in burn patients.


Les infections nosocomiales sont une préoccupation majeure du traitement bien conduit des brûlés. Cette étude a eu pour but d'évaluer l'incidence, les facteurs de risque de survenue et les bactéries isolées d'infections nosocomiales survenues dans le CTB de Kulna (Bangladesh). Elle a étudié les dossiers l'ensemble des 100 patients admis dans le CTB du CHU de Kulna en 2020. Les analyses bactériologiques ont été réalisées dans le laboratoire du CHU. Une régression logistique a été utilisée pour déterminer les facteurs de risque d'infection. Toutes les analyses statistiques ont été réalisées avec SSPS 26.0. L'âge moyen était de 29,2 ans, le sex-ratio de 1,3H/1F. Les flammes représentaient 41% des causes, les liquides 23% et l'électricité 15%. Quasiment 40% des patients avaient des brûlures profondes. L'incidence des accidents infectieux était de 42% (cutanée 33%, bactériémies 9%). Les facteurs de risque indépendants de survenue d'une infection étaient une atteinte sur >40 % SCT (OR 7,56; IC95 2,89-19,81), une brûlure profonde (OR 34,40 ; IC95 3,25-97,14) et un séjour prolongé (OR 1,31; IC95 1,15-1,51). Les quatre bactéries les plus fréquentes étaient S. aureus (45%), Streptococcus spp (24%), P. æruginosa (19%), et E. coli (12%). Les épidémiologies bactériennes variant selon les services d'où elles sont issues, c'est sur l'épidémiologie locale que doivent se centre les mesures de contrôle des infections nosocomiales.

RESUMEN

Pheretima posthuma (Vaillant, 1868), a native earthworm of Pakistan and Southeast Asia, has wide utilization in vermicomposting and bioremediation process. In this study, P. posthuma coelomic fluid (PCF) and body paste (PBP) was evaluated as antibacterial agent against ampicillin (AMP) resistant five Gram positive and four Gram negative clinical isolates. The antibacterial effect of different doses (i.e. 25-100 µg/ml) of PCF and PBP along with AMP and azithromycin (AZM) (negative and positive controls, respectively) were observed through disc diffusion and micro-dilution methods. All nine clinical isolates were noticed as AMP resistant and AZM sensitive. Antibacterial effects of PCF and PBP were dose dependent and zone of inhibitions (ZI) against all clinical isolates were between 23.4 ± 0.92 to 0 ± 00 mm. The sensitivity profile of PCF and PBP against clinical isolates was noticed as 44.44 and 55.56%, respectively. Both PCF and PBP showed bacteriostatic (BTS) action against S. aureus, S. pyogenes, K. pneumonia, N. gonorrhoeae. Moreover, the cumulative BTS potential of PCF and PBP against all isolates was 66.67 and 55.56%, respectively. The MICs of PCF and PBP were ranged from 50-200 µg/ml against selected isolates. The bacterial growth curves indicated that PCF and PBP inhibited the growth of all isolates at their specific MIC concentrations. However, PBP has better antibacterial potential compared to PCF against selected isolates. Therefore, it is concluded that both PCF and PBP of P. posthuma possess antibacterial and BTS potential against ampicillin resistant clinical isolates. This organism might be considered as a second choice of antibacterial agents and can further be utilized in pharmaceutical industries for novel drug manufacturing by prospecting bioactive potential agents.

RESUMEN

Primary amenorrhea is a serious medical condition. A thorough clinical assessment is necessary for a timely and correct diagnosis and management of this ailment to prevent long-term health and social problems. Turner's syndrome is considered one of the important causes of primary amenorrhea, with an incidence of one in 2,500 to one in 3,000 live-born girls. In this report, we present an interesting case involving multinodular goiter, hypothyroidism, and primary amenorrhea. A 24-year-old woman with a history of multinodular goiter and hypothyroidism attended an endocrine clinic with fine-needle aspiration cytology (FNAC) report of her bilateral thyroid nodules, which showed Bethesda category IV. She had a history of learning difficulties. During detailed history-taking, the patient also complained of primary amenorrhea. Clinical examination showed a lack of secondary sexual characters. Biochemical, imaging, and cytogenetic investigations were suggestive of absent ovaries and fallopian tubes, streaked uterus, hypergonadotropic hypogonadism, and X0 karyotyping. The learning objectives of this case report are as follows: firstly, in countries with a lack of awareness and limited health resources, patients may present with one of the manifestations of Turner's syndrome. Clinicians from all specialties should be aware of the clinical features of this relatively rare entity and should try to make the most of incidental clinical findings. Secondly, clinicians should be more vigilant and thorough in their clinical assessment of patients with learning difficulties to minimize the chances of missing a clinical diagnosis.

RESUMEN

Chemical phase and distribution of natural radionuclides (226Ra, 232Th and 40K) were determined for sand samples collected from ten different beaches of Karachi. All samples, except one, were identified with major and minor phases as SiO2 and CaCO3, respectively. The average activity concentrations were 24.9, 25.0 and 239 Bq kg-1 for 226Ra, 232Th and 40K, respectively. Including all samples, the average radium equivalent activity was 79.1 Bq kg-1. The external and internal radiation hazard indices and representative level index were all found below unity. The average air absorbed dose rate at 1 m above the sand due to the natural radionuclides was 18.3 nGy h-1, which was less than the world average for soil. The corresponding annual effective dose rate was 22.4 µSv y-1. It was found that Raeq had positive significant correlation with the amount of quartz present at the beaches.

RESUMEN

We describe the case of a 32-year-old man with repaired cleft lip complaining of sexual difficulties, which were determined to be multifactorial in origin. A negative body impression, anatomical difficulty in engaging in sexual acts, the indirect impact of secondary complications of cleft lip, and the negative perception of his dysmorphia from potential sexual partners led to his current state. Cleft lip and palate (CLP) are the most common malformations of the craniofacial region. The malformations of anatomical structures involved in CLP can manifest through several variations of clinical features and phenotypes, typically affecting hearing, social integration, speech, and feeding. From birth to the end of growth, a multidisciplinary approach involving orthodontists, speech therapists, psychologists, and social workers is essential for adequate management, even after surgical repair. This case report illustrates the critical importance of the functionality of normal lips essential for sexual function and psychosocial issues encountered in a patient with repaired cleft lip, as this issue likely has a higher prevalence than the literature actually suggests. Adding a psychiatrist on the panel for pediatric reconstructive surgery teams and post-repair rehabilitation would be essential to managing potential sexual and psychological issues into adulthood.

RESUMEN

BACKGROUND: Diabetes mellitus is a vastly prevalent metabolic disorder with escalating global health concerns. Particularly when mismanaged, chronic micro- and macrovascular complications may highly impair physiological systems while immunodeficiency disposes us to infection. OBJECTIVE: We investigate infections, localized complications, and neoplasms of the genitourinary system secondary to the chronic complications of diabetes mellitus in males and females. METHOD: A comprehensive MEDLINE® search was guided using key words relevant to diabetes mellitus and the genitourinary system. RESULTS: Pathogen-friendly environments may implicate the sequelae of urinary tract and genital mycotic infections, potentially generating necrosis, abscess, and other inflammatory complications, which may present concomitantly with neurogenic and/or vasculogenic dysfunction to further exacerbate an existing genitourinary condition. Manifestations of the adrenal, renal, and genital organs and tissues are discussed as they relate to vascular, immunodeficient, and other hyperglycemic complications of the diabetic state. Among those, chronic kidney disease and cystopathy are the most prevailing and detrimental. Though studies have connected diabetes to either an increased risk of developing or poor prognosis of bladder, renal, prostate, endometrial, and cervical cancers, the explicit biological relationships are as of yet inconclusive. CONCLUSION: Despite the availability of precise treatments to ameliorate most presently reviewed conditions, particularly urinary tract and genital mycotic infection-related sequelae, reversing permanent vascular damage remains a great challenge. Leading a healthier lifestyle and managing diabetes mellitus with a patient-centric approach from the outset are the most putative methods for preventing critical long-term genitourinary manifestations of diabetes mellitus.

RESUMEN

BACKGROUND: Uncontrolled or long-term diabetes mellitus is conducive to vascular and oxidative stress disturbances that impede several physiological systems, which may in turn elicit psychological symptoms. OBJECTIVE: We assess the sexual and hormonal complications of diabetes mellitus that impair reproductive function in males and females. METHODS: A comprehensive MEDLINE® search was guided using key words relevant to diabetes mellitus and reproductive health. RESULTS: We reviewed the pathogenesis, clinical manifestations, imaging modalities, pharmacological treatment, and intervention options for each diabetic reproductive complication in males and females. Erectile dysfunction secondary to angiopathic, neuropathic, and myopathic damage is a leading complication of diabetes in males. Other reproductive complications include ejaculatory dysfunction, hypogonadism, modified semen parameters, and delayed puberty. Specifics of reproductive dysfunction in diabetic women are less definite than in men due to the lack of standardized evaluation of sexual function in women as well as the increased role of psychological morbidity. Despite this, it is known to manifest as hypogonadism, hypoactive sexual desire disorder, dyspareunia, menstrual dysfunction, and polycystic ovarian syndrome. CONCLUSION: Longitudinal studies with larger sample sizes are necessary to better comprehend the connection between diabetes and sexual dysfunction, chiefly in females. Understanding and dividing the role of fertility and sexual issues in reproductive dysfunction can help guide evaluation and management.

RESUMEN

BACKGROUND AND PURPOSE: Rhabdomyolysis is well known after traumatic crush injuries or ischemia involving muscles. Postoperatively, it most likely is secondary to surgical positioning and patient muscle mass. We report a case after laparoscopic live-donor nephrectomy. CASE REPORT: A muscular 35-year-old man underwent elective left laparoscopic live-donor nephrectomy in a 70 degrees flank position with four ports. He was in the right-side lying position with hip flexion (flank position) for approximately 4 hours. A kidney bridge had been placed between the iliac crest and the rib cage. Postoperatively, the patient had light-pinkish urine and low urine output. There was marked induration of the buttocks and significant pedal and scrotal edema. With judicious use of alkalinization and diuretics, the patient did not require dialysis, and renal function returned to base level by postoperative day 20. The recipient of the kidney had a normal postoperative course. CONCLUSION: Rhabdomyolysis is a syndrome of muscle necrosis and release of intracellular components into the circulation. Acute renal failure secondary to myoglobinuria is a common complication. We currently use little flexion of the table during donor nephrectomy and bring the table to a neutral position immediately after kidney retrieval. Postoperatively, one needs a high index of suspicion for rhabdomyolysis to avoid or at least promptly recognize this rare but potentially serious condition after any operation lasting >or=4 hours.

RESUMEN

INTRODUCTION: Pneumoscrotum is a critical, physical finding that may indicate significant morbidity and mortality. Accumulation of gas in the scrotum can be primary or secondary. OBJECTIVE: This paper discusses rapid diagnosis and treatment options. MATERIAL AND METHODS: PubMed searches for pneumoscrotum, etiology, diagnosis, and treatment. RESULTS: We review the historical perspective, classification, etiology, diagnosis, and treatment options of pneumoscrotum, as well as the presentation of pneumoscrotum in neonates/infants. CONCLUSION: It is crucial to diagnose the etiology pneumoscrotum and designing a treatment option based off that.

RESUMEN

Seminal vesicles (SVs) are sex accessory organs and part of male genitourinary system. They play a critical role in male fertility. Diseases of the SVs, usually results in infertility. Diseases of the SVs are extremely rare and are infrequently reported in the literature. We address the current literature of SV pathologies, symptoms, diagnosis, and treatment options. We review the clinical importance of SVs from PubMed. The current imaging modalities and instrumentation that help diagnose SV diseases are reviewed. Common pathologies including, infection, cysts, tumors, and congenital diseases of the SVs are addressed. Many times symptoms of hematospermia, pain, irritative and obstructive lower urinary tract symptoms, and infertility are presented in patients with SV diseases.

RESUMEN

INTRODUCTION: Glomus tumors are benign neoplasms commonly found in subungual regions of the extremities and rarely located in the penis. Misdiagnosis of glomus tumors is common; therefore, symptoms and clinical presentations should be reviewed. OBJECTIVE: The primary objective of this review article is to emphasize the pathogenesis, pathology, clinical presentation, symptoms, diagnosis, and treatment methods of glomus tumors in order to better identify and manage the condition. MATERIALS AND METHODS: Research was conducted using PubMed/Medline. The inclusion criteria required glomus tumor to be present on the penis. RESULTS: Glomus tumors, which appear as symptomatic or asymptomatic lesions, are attributed to dispersion grouping of neoplastic or non-neoplastic lesions in a particular area. CONCLUSION: Differential diagnosis of glomus tumors includes hemangiomas, neurofibromatosis, epithelial lesions, and spindle-cell lesions. Physical examination and histological findings should be used for diagnosis. Treatment options can be either conservative or invasive, in which the patient undergoes surgical excision.

RESUMEN

INTRODUCTION: Uterine leiomyomas are common gynecologic tumor in reproductive-aged women, by age 50, diagnosis shared by urologist, gynecologists and radiologists. OBJECTIVE: The goal of this article is to review the current literature, study the impact of leiomyoma on female lower urinary tract, examine the cause female sexual dysfunction and provide a comprehensive review of current diagnostic, imaging studies, and current treatment of leiomyoma. METHODS: Clinical leiomyoma studies published from 1956 through 2015 were identified using the PubMed search engines and the key words leiomyoma, fibroid in the current literature. Impact of leiomyoma on the lower urinary tract including female sexual dysfunction was reviewed with terms of "urinary retention", "bladder", "urethra", "dyspareunia", "incontinence", "incomplete bladder emptying", "female sexual dysfunction", and "lower urinary tract" to study the urological and sexual effects of leiomyoma. Literature related to leiomyoma was reviewed from 1965 to present. RESULTS: Women with uterine leiomyomata complained of pelvic pain, menstrual irregularities, infertility, lower urinary tract symptoms and sexual dysfunction. CONCLUSION: Leiomyoma is a common tumor of the uterus that often clinically impacts on the lower urinary tract and results in urological and sexual symptoms. Leiomyoma can compress and grow into and become adherent to the bladder and surrounding pelvic organs or metastasize into peritoneal organs. Leiomyoma can enlarge and compress the urinary bladder, urethra, and lower end of the ureters. Leiomyoma can cause embarrassing sexual dysfunction in females. Current literature of non-surgical and surgical therapy of leiomyoma is described.

RESUMEN

PURPOSE: We describe extraperitoneal laparoscopic resection of large prostatic adenomas (<100 g) as an alternative to open simple prostatectomy by both the transcapsular or Millin and the transvesical approaches. PATIENTS AND METHODS: We have performed more than 20 laparoscopic prostatectomies (adenomectomies) for benign prostatic hyperplasia (BPH) for glands >100 g. The initial two cases, with follow-up longer than 1 year, are included in this report. Using an extraperitoneal approach, enucleation of the obstructing prostatic lobes was performed with the aid of a Harmonic Scalpel and laparoscopic claw forceps. Hemostatic sutures were placed at 5 and 7 o'clock. The urethrovesical junction (transvesical) or capsulotomy (Millin) were closed in an interrupted fashion using intracorporeal sutures. RESULTS: Both procedures were successful. The total operative time was 180 minutes for first the case and 120 minutes for the second. The adenoma removed was approximately 138 g in the first case and 102 g in the second case. The estimated blood loss was <50 mL and <200 mL, respectively. The postoperative courses were unremarkable. Analgesic requirements were minimal, and the patient was discharged on postoperative day 2 and 3, respectively. A follow-up examination at 1, 3, 6, and 12 months showed that the flow rate is >20 mL and the postvoiding residual volume 0, with normal continence and sexual potency in both men. CONCLUSIONS: Extraperitoneal laparoscopic simple prostatectomy is a simple straightforward technique. Minimal bleeding, a reduced transfusion rate, shorter hospitalization, and faster recovery are additional advantages. This minimally invasive technique is a reasonable alternative to open simple prostatectomy for large glands with reduced morbidity.
