RESUMO

Chronic idiopathic ulcers of the colon pose diagnostic challenges due to their elusive etiology and potential resemblance to other intestinal pathologies, such as cecal carcinoma. This case report outlines the clinical course of a 68-year-old female patient who presented to the emergency department (ED) with persistent right lower quadrant pain. Despite multiple hospital visits yielding varied diagnoses, a definitive diagnosis was only made following a laparoscopic partial colectomy, which revealed chronic idiopathic ulcers with transmural scarring and adhesions to adjacent small intestine loops. Histological examination demonstrated a substantial ulcer bed populated by inflammatory cells, including large stellate and spindled stromal cells within the granulation tissue, alongside lymphoid hyperplasia and scar tissue extending into the muscularis propria. The initial presentation of this case could easily be mistaken for appendicitis, diverticulitis, carcinoma, or irritable bowel syndrome, highlighting the significance of considering chronic idiopathic ulcers in the differential diagnosis of patients presenting with cecal masses.

RESUMO

A 52-year-old woman, with a multifaceted medical background encompassing spinal cord injury, pneumonia, and recurrent hospitalizations, presents with enduring left hip and leg discomfort ultimately diagnosed as avascular necrosis (AVN). She previously underwent intraosseous direct anterior arthroplasty (DAA) of the left hip during the removal of orthopedic artifacts. Despite enduring hypertension, severe trochanter dislocation, and prosthesis fracture, she recovered and required additional surgery to address the dislocation and fracture. This case underscores the challenges in diagnosing and treating AVN, emphasizing the importance of meticulous postoperative care and a multidisciplinary approach. Challenges highlighted by AVN include delayed diagnosis, intricate surgical procedures, and the potential need for further interventions due to hardware complications and infection as seen in this patient.

RESUMO

Ayurveda, an ancient holistic and personalized healing system originating from the Indian subcontinent, has been gaining increasing attention as a complementary and alternative medical practice for treating various health conditions, including those related to women's reproductive well-being. This comprehensive literature review examines a wide array of experimental and clinical studies exploring the diverse facets of Ayurvedic interventions in addressing issues such as menstrual irregularities, polycystic ovary syndrome (PCOS), infertility, and menopausal symptoms. The paper specifically focuses on discussing the available data regarding the efficacy of Tulsi (Ocimum tenuiflorum), ashwagandha (Withania somnifera), ginger (Zingiber officinale), cardamom (Elettaria cardamomum), turmeric (Curcuma longa), and Shatavari (Asparagus racemosus), which have traditionally been used in Ayurvedic medicine for centuries. The synthesis of literature not only highlights the potential benefits of these Ayurvedic interventions, but also critically assesses the methodological rigor of existing studies, identifying research gaps, and proposing directions for future investigations. While acknowledging the need for further rigorous research and clinical trials, the review emphasizes the benefits of collaborative and integrative healthcare. This review aims to serve as a valuable resource for healthcare practitioners, researchers, and individuals seeking holistic and natural alternatives for female reproductive health management.

RESUMO

Hysterectomy, one of the most common surgical procedures performed in women worldwide, assumes a very important role in the definitive management of diverse gynecologic conditions. This case report presents a compelling instance of an iatrogenic bladder perforation that occurred during laparoscopically assisted vaginal hysterectomy in a 47-year-old woman with a high body mass index, extensive surgical history, and postural orthostatic tachycardia syndrome. Despite considerable preoperative planning and the use of minimally invasive techniques, the occurrence of physician-induced bladder perforation highlights the significance of understanding anatomical relationships and variations. The patient's previous abdominal surgeries including two cesarean sections, appendectomy, and cholecystectomy likely contributed to scar formation and adhesions, making dissection challenging. The case report and following discussion delve into anatomical variations, as well as the diagnosis and management of iatrogenic bladder injuries. The presented case serves as a valuable addition to the literature, contributing insights into the challenges and considerations surrounding urinary tract injuries during hysterectomy. This paper aims to review current research and guide practicing obstetricians and gynecologists in the management of intraoperative bladder injuries.

RESUMO

Exploring the intricacies of managing high-risk pregnancies complicated by intrauterine growth restriction (IUGR), placenta previa, and a single umbilical artery requires a comprehensive understanding of their etiologies, mechanisms, and treatment recommendations. This case report delves into the clinical course of a 34-year-old smoker with a pre-pregnancy body mass index of 14.2 kg/m2, shedding light on the considerations posed by a pregnancy in which several risk factors are superimposed on one another. IUGR, affecting 10%-15% of pregnancies, elevated the risk of adverse outcomes during labor and delivery, necessitating careful antenatal monitoring. Placenta previa, with an incidence of 0.3% to 2% in pregnancies, introduced further complications impacting delivery modes and raising the risk of hemorrhage. This report aims to showcase the interconnectedness between these various obstetrical complications and risk factors, to guide maternal-fetal-medicine specialists in making informed decisions during the management of high-risk pregnancies.

RESUMO

A 64-year-old African American male with a history of hypertension and type II diabetes mellitus presented with unexplained upper lip lacerations after several frequent episodes of hemoptysis. Following the upper lip lacerations were several weeks of intermittent unknown episodic fevers. The patient, challenged by impaired mobility, exhibited an array of symptoms, including severe upper lip pain with lacerations and white patches on the tongue. Laboratory findings indicated thrombocytopenia and anemia, with positive tests for both influenza A and B. Despite completing Tamiflu, the patient experienced recurrent fevers. Imaging revealed gastrointestinal abnormalities, leading to the initiation of nystatin and a multi-antibiotic regimen without significant fever resolution. A subsequent tongue biopsy revealed verruca lesions, and acyclovir was initiated. Despite this, the patient developed lip and facial blisters. Negative results from cytomegalovirus (CMV) deoxyribonucleic acid (DNA) polymerase chain reaction (PCR) prompted a shift in focus to managing persistent fevers, ultimately controlled with naproxen but without discoverable cause. This case underscores the diagnostic challenge posed by unexplained fevers in an elderly patient with oral manifestations. The protracted course and evolving symptoms emphasize the intricacies of managing such cases, highlighting the need for continued investigation and collaboration across medical disciplines in navigating complex clinical scenarios.

RESUMO

Tumefactive Crohn's disease is a rare form of Crohn's disease that may mimic colon carcinoma macroscopically. This case report describes a 28-year-old female who presented with right-sided abdominal pain and a palpable abdominal mass that had persisted for over a month. Multiple hospitalizations failed to provide an accurate diagnosis until an exploratory laparotomy revealed that the "mass" was the cecum and a perforated ascending colon. A partial right colectomy was performed, sending the specimen for biopsy. The microscopic description showed dense and confluent chronic inflammation in the colonic mucosa and wall, extending to the serosa in some regions. The infiltration comprised lymphocytes and plasma cells, with an admixture of some neutrophils. Aphthous mucosal ulcerations, intramural fissures, and fistulas were present. Immunostains for pan-keratin demonstrated no intramural epithelial elements. The characteristics of this lesion represent tumefactive Crohn's disease. This case highlights the key microscopic characteristics that pathologists look for when differentiating Crohn's disease from colon carcinoma in a patient presenting with abdominal pain and a colon mass.

RESUMO

Granulomatosis with polyangiitis (GPA) is a rare autoimmune disease that affects multiple organs and causes inflammation, necrosis, and vasculitis in small blood vessels. Treatment for GPA involves achieving and maintaining remission. In recent studies, cyclophosphamide-based regimens have been linked to comorbidity hazards, including an increased risk of malignancies, especially hematological ones. Acute myeloid leukemia is the main hematologic malignancy that can complicate GPA. In this context, we report the case of a middle-aged woman with GPA who developed acute promyelocytic leukemia (APL) during maintenance with cyclophosphamide. She was treated with all-trans retinoic acid at 50 mg/day and arsenic trioxide at 10 mg/day, along with steroids. This case highlights the unique emergence of APL in a GPA patient during cyclophosphamide therapy. A single case has previously been reported on the development of APL in a patient with GPA while using azathioprine monotherapy for 2 years.

RESUMO

Drug development is a time-consuming and expensive process, given the low success rate of clinical trials. Now, anticancer drug developments have shifted to three-dimensional (3D) models which are more likely to mimic tumor behavior compared to traditional two-dimensional (2D) cultures. A comparative study among different aspects was conducted between 2D and 3D cultures using colorectal cancer (CRC) cell lines, in addition, Formalin-Fixed Paraffin-Embedded (FFPE) block samples of patients with CRC were used for evaluation. Compared to the 2D culture, cells grown in 3D displayed significant (p < 0.01) differences in the pattern of cell proliferation over time, cell death phase profile, expression of tumorgenicity-related genes, and responsiveness to 5-fluorouracil, cisplatin, and doxorubicin. Epigenetically, 3D cultures and FFPE shared the same methylation pattern and microRNA expression, while 2D cells showed elevation in methylation rate and altered microRNA expression. Lastly, transcriptomic study depending on RNA sequencing and thorough bioinformatic analyses showed significant (p-adj < 0.05) dissimilarity in gene expression profile between 2D and 3D cultures involving thousands of genes (up/down-regulated) of multiple pathways for each cell line. Taken together, the study provides insights into variations in cellular morphologies between cells cultured in 2D and 3D models.

RESUMO

BACKGROUND: Palliative care (PC) can reduce symptom distress and improve quality of life for patients and their families experiencing life-threatening illness. While the need for PC in Kenya is high, PC service delivery and research is limited. Qualitative research is needed to explore potential areas for PC research and support needed to enable that research. This insight is critical for informing a national PC research agenda and mobilizing limited resources for conducting rigorous PC research in Kenya. OBJECTIVES: To explore perceptions of priority areas for PC research and support needed to facilitate rigorous research from the perspective of Kenyan PC providers and leaders. METHODS: Focus groups (FGs) were conducted in November and December of 2018 using a semi-structured interview guide. FGs were audio-recorded, transcribed, and analyzed using a thematic content analysis approach. RESULTS: Three FGs were conducted (n = 22 participants). Ten themes related to PC research emerged, including research on: 1) beliefs about death, disease, and treatment to inform PC; 2) awareness about PC, 3) integration of PC within the health system; 4) understanding caregiver experiences and needs; 5) community health volunteers (CHVs) and volunteer programs; 6) evaluation of costs and benefits of PC; 7) treatment approaches, including complementary and alternative medicine (CAM) and advanced diagnostics at end of life; 8) other suggestions for research, 9) populations in need of PC research; and 10) resources for enabling research. CONCLUSIONS: Kenyan PC providers and leaders identified key areas requiring increased scientific inquiry and critical resources needed to enable this research. These findings can help to focus future PC research in Kenya and encourage funding agencies to prioritize the issues identified.

RESUMO

OBJECTIVES: Gastric cancer is a heterogeneous malignancy in terms of stage-wise prognosis. This study aimed at finding any prognostic significance of preoperative carcinoembryonic antigen (CEA) and cancer antigen (CA) 19-9 in resectable gastric cancer. METHODS: A total of 57 patients at Kidwai Memorial Institute of Oncology, Bengaluru, India from January 2022 to March 2023 were included in this observational prospective study. Included patients had a resectable tumor at clinical staging. Patients were divided into two categories (raised and non-raised) based on serum tumor marker (CEA and CA 19-9) levels. Their relationship with clinicopathological features was studied. The association was studied using chi-square test, and p-value <0.05 was considered significant. RESULTS: The mean age of the study group was 55.47 years with male predominance (63.2%, n=36). Raised CEA and CA 19-9 were seen in 15.8% (n=9) and 10.5% (n=6) patients, respectively, while both markers were raised in 5.3% (n=3). Raised CEA was found significantly associated with grade 3 adenocarcinoma stomach (OR 7.825, 95%CI: 1.374-44.562; p= 0.020) and intraoperative finding of inoperability due to occult intra-abdominal disease (p<0.05). CA 19-9 (pre- and post-operative levels) had no statistically significant association (p>0.05) with the grade of adenocarcinoma. CONCLUSION: This study indicates a benefit in estimating CEA for the prediction of prognosis in gastric cancer. CEA levels have been found to predict chances of finding occult intra-abdominal metastasis in gastric cancer.

RESUMO

Necrotizing fasciitis is a life-threatening bacterial infection characterized by rapid tissue destruction and systemic inflammation. Although it is rare, it can occur at surgical incision sites in procedures such as open abdominal hysterectomy. Prompt diagnosis and treatment are essential to prevent sepsis and multi-organ failure. We present a case of a 39-year-old morbidly obese African American woman with a history of type II diabetes that developed necrotizing fasciitis at a transverse incision site following an abdominal hysterectomy. The infection was complicated by a urinary tract infection caused by Proteus mirabilis. Surgical debridement and antibiotic therapy were successfully employed to treat the infection. This case emphasizes the importance of clinical suspicion, early intervention, and appropriate antimicrobial therapy in managing necrotizing fasciitis at incision sites, particularly in patients with additional risk factors.

RESUMO

INTRODUCTION: Cancer is a major issue in medical science with increasing death cases every year worldwide. Therefore, searching for alternatives and nonorthodox methods of treatments with high efficiency, selectivity and less toxicity is the main goal in fighting cancer. Acetyl-11-keto-ß-boswellic acid (AKBA), is a derivative pentacyclic triterpenoid that exhibited various biological activities with potential anti-tumoral agents. In this research, AKBA was utilized to examine the potential cytotoxic activity against MCF-7 cells in vitro and monitor the cellular and morphological changes with a prospective impact on apoptosis induction. METHODS: The cytotoxic activity of AKBA was measured by 3(4,5dimethylthiazole- 2-yl)-2,5 diphyneltetrazolium bromide (MTT) assay. A dose-dependent inhibition in MCF-7 cell viability was detected. The clonogenicity of MCF-7 cells was significantly suppressed by AKBA increment in comparison with untreated cells. RESULT: Morphologically, exposure of MCF-7 cells to high AKBA concentrations caused changes in cell nuclear morphology which was indicated by increasing in nuclear size and cell permeability intensity. The mitochondrial membrane potential (ΔΨm) was reduced by increasing AKBA concentration with a significant release of cytochrome c. Acridine orange/ethidium bromide dual staining experiment confirmed that MCF-7 cells treated with AKBA (IC50 concentration) displayed a late stage of apoptosis indicated by intense and bright reddish colour. CONCLUSION: A significant increase in reactive oxygen species formation was observed. Caspase 8 and caspase 9 activities were estimated and AKBA activated the production of caspase 8 and caspase 9 in a dose-dependent pattern. Finally, the cell phase distribution analysis was conducted, and flow cytometric analysis showed that AKBA at 200 µg mL-1 significantly arrest MCF-7 cells at the G1 phase and triggered apoptosis.

RESUMO

OBJECTIVES: This study aimed to determine mastoid emissary canal's (MEC) and mastoid foramen (MF) prevalence and morphometric characteristics on cone-beam computed tomography (CBCT) images to underline its clinical significance and discuss its surgical consequences. METHODS: In the retrospective analysis, two oral and maxillofacial radiologists analyzed the CBCT images of 135 patients (270 sides). The biggest MF and MEC were measured in the images evaluated in MultiPlanar Reconstruction (MPR) views. The MF and MEC mean diameters were calculated. The mastoid foramina number was recorded. The prevalence of MF was studied according to gender and side of the patient. RESULTS: The overall prevalence of MEC and MF was 119 (88.1%). The prevalence of MEC and MF is 55.5% in females and 44.5% in males. MEC and MF were identified as bilateral in 80 patients (67.20%) and unilateral in 39 patients (32.80%). The mean diameter of MF was 2.4 ± 0.9 mm. The mean height of MF was 2.3 ± 0.9. The mean diameter of the MEC was 2.1 ± 0.8, and the mean height of the MEC was 2.1 ± 0.8. There is a statistical difference between the genders (p = 0.043) in foramen diameter. Males had a significantly larger mean diameter of MF in comparison to females. CONCLUSION: MEC and MF must be evaluated thoroughly if the surgery is contemplated. Radiologists and surgeons should be aware of mastoid emissary canal morphology, variations, clinical relevance, and surgical consequences while operating in the suboccipital and mastoid areas to avoid unexpected and catastrophic complications. CBCT may be a reliable imaging diagnostic technique.

RESUMO

Mönckeberg medial arteriosclerosis is a condition characterized by the calcification of the tunica media layer of the blood vessels that are visible on plain radiography or sectional tomography. In dentistry, a properly acquired panoramic radiograph may show the condition incidentally. It is also known as medial arterial calcinosis and can be associated with diabetes mellitus or chronic kidney disease. This condition is different from the more common atherosclerosis where the tunica intima remains unaffected, and the diameter of the vessel lumen is preserved. Dental treatment can be performed when the patient is stable with medically controlled diabetes.

RESUMO

OBJECTIVE: This study aimed to examine the morphological characteristics of the nasopharynx in unilateral Cleft lip/palate (CL/P) children and non-cleft children using cone beam computed tomography (CBCT). METHODS: A retrospective study consisted of 54 patients, of which 27 patients were unilateral CL/P, remaining 27 patients have no CL/P. Eustachian tubes orifice (ET), Rosenmuller fossa (RF) depth, presence of pharyngeal bursa (PB), the distance of posterior nasal spine (PNS)-pharynx posterior wall were quantitatively evaluated. RESULTS: The main effect of the CL/P groups was found to be effective on RF depth-right (p < 0.001) and RF depth-left (p < 0.001). The interaction effect of gender and CL/P groups was not influential on measurements. The cleft-side main effect was found to be effective on RF depth-left (p < 0.001) and RF depth-right (p = 0002). There was no statistically significant relationship between CL/P groups and the presence of bursa pharyngea. CONCLUSIONS: Because it is the most common site of nasopharyngeal carcinoma (NPC), the anatomy of the nasopharynx should be well known in the early diagnosis of NPC.

RESUMO

PURPOSE: Occult hernias, hernias seen on radiologic imaging but not felt on physical exam, are common. Despite their high prevalence, little is known about the natural history of this finding. Our aim was to determine and report on the natural history of patients with occult hernias including the impact on abdominal wall quality of life (AW-QOL), need for surgery, and risk of acute incarceration/strangulation. METHODS: This was a prospective cohort study of patients who underwent a computed tomography (CT) abdomen/pelvis scan from 2016 to 2018. Primary outcome was change in AW-QOL using the modified Activities Assessment Scale (mAAS), a hernia-specific, validated survey (1 = poor, 100 = perfect). Secondary outcomes included elective and emergent hernia repairs. RESULTS: A total of 131 (65.8%) patients with occult hernias completed follow-up with a median (IQR) of 15.4 (22.5) months. Nearly half of these patients (42.8%) experienced a decrease in their AW-QOL, 26.0% were unchanged, and 31.3% reported improvement. One-fourth of patients (27.5%) underwent abdominal surgery during the study period: 9.9% were abdominal procedures without hernia repair, 16.0% involved elective hernia repairs, and 1.5% were emergent hernia repairs. AW-QOL improved for patients who underwent hernia repair (+ 11.2 ± 39.7, p = 0.043) while those who did not undergo hernia repair experienced no change in AW-QOL (- 3.0 ± 35.1). CONCLUSION: When untreated, patients with occult hernias on average experience no change in their AW-QOL. However, many patients experience improvement in AW-QOL after hernia repair. Additionally, occult hernias have a small but real risk of incarceration requiring emergent repair. Further research is needed to develop tailored treatment strategies.

RESUMO

OBJECTIVE: A systematic review was undertaken to examine the spontaneous of craniofacial fibrous dysplasia (FD) into osteosarcoma (OS). STUDY DESIGN: Five databases were searched, and data were evaluated in 2 subsets: (1) frequency analysis involving only cross-sectional studies that specifically examined patients for osteosarcomatous transformation, thereby allowing a calculation of the frequency of transformation of craniofacial FD, and (2) case analysis of case reports and case series of FD that underwent osteosarcomatous transformation. Quality assessment of the studies in the frequency and case analyses was performed. RESULTS: Seven cross-sectional studies involving 779 patients in the frequency analysis documented transformation of craniofacial FD into OS in 13 patients, for a frequency of 1.67%. Of the 18 separate cases of osteosarcomatous transformation in the case analysis, 11 (61.1%) occurred in females, 11 (61.1%) developed from monostotic FD, and 7 (38.9%) arose in the mandible, with 5 in the maxilla (27.8%) and 6 (33.3%) in other craniofacial sites. The mean age of the patients at the time of malignant diagnosis was 36.4 years, with an average of 11.3 years from FD diagnosis to the appearance of OS. The quality of the articles ranged from fair to excellent. CONCLUSIONS: The risk of osteosarcomatous transformation of craniofacial FD is low, but the possibility of transformation should be taken into consideration by clinicians, as this will guide treatment and follow-up regimens.

RESUMO

STUDY DESIGN: This was a retrospective comparative study. OBJECTIVE: To compare the likelihood of approach-related complications for patients undergoing single-level lateral lumbar interbody fusion (LLIF) at L4-L5 to those undergoing the procedure at upper lumbar levels. SUMMARY OF BACKGROUND DATA: LLIF has been associated with a number of advantages when compared with traditional interbody fusion techniques. However, potential risks with the approach include vascular or visceral injury, thigh dysesthesias, and lumbar plexus injury. There are concerns of a higher risk of these complications at the L4-L5 level compared with upper lumbar levels. MATERIALS AND METHODS: A retrospective cohort review was completed for consecutive patients undergoing single-level LLIF between 2004 and 2019 by a single surgeon. Indication for surgery was symptomatic degenerative lumbar stenosis and/or spondylolisthesis. Patients were divided into 2 cohorts: LLIF at L4-L5 versus a single level between L1 and L4. Baseline characteristics, intraoperative complications, postoperative approach-related neurological symptoms, and patient-reported outcomes were compared and analyzed between the cohorts. RESULTS: A total of 122 were included in analysis, of which 58 underwent LLIF at L4-L5 and 64 underwent LLIF between L1 and L4. There were no visceral or vascular injuries or lumbar plexus injuries in either cohort. There was no significant difference in the rate of postoperative hip pain, anterior thigh dysesthesias, and/or hip flexor weakness between the cohorts (53.5% L4-L5 vs. 37.5% L1-L4; P =0.102). All patients reported complete resolution of these symptoms by 6-month postoperative follow-up. DISCUSSION: LLIF surgery at the L4-L5 level is associated with a similar infrequent likelihood of approach-related complications and postoperative hip pain, thigh dysesthesias, and hip flexor weakness when compared with upper lumbar level LLIF. Careful patient selection, meticulous use of real-time neuromonitoring, and an understanding of the anatomic location of the lumbar plexus to the working corridor are critical to success.

RESUMO

The study planned to estimate biological parameters linked to rheumatoid arthritis (RA) patients, detecting the influence of MTX and biotherapy treatments on these parameters and synthesizing methotrexate bovine serum albumin nanoparticles linked to folate (FA-MTX-BSA NPs) to reduce the overwhelming expression of inflammatory cytokines. Inflammatory parameters showed significant increases in newly diagnosed and MTX-receiving groups while no changes were observed in the biotherapy-maintained group. MTX-loaded BSA nanoparticles were fabricated by the desolvation method and further linked to activated folic acid to obtain FA-MTX-BSA NPs. FA-MTX-BSA NPs were successfully characterized within the nanoscale range using different screening techniques. FA-MTX-BSA NPs showed an in vitro release in a sustained manner. The potential of MTX, MTX-BSA NPs, and FA-MTX-BSA NPs in inducing cytokine level reduction was detected. Significant decreases in interleukin- 1 beta (IL-1ß), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α) levels were obtained in cultures treated with FA-MTX-BSA NPs compared to the untreated culture in a dose-dependent pattern. Furthermore, FA-MTX-BSA NPs comparing with MTX and MTX-BSA NPs exhibited a significant advanced effect in decreasing cytokines levels. Accordingly, the conjunction of BSA NPs and MTX linked to folate potentially reduced cytokines manifestation in RA.
