RESUMO

The immune system plays a critical role in inflammation by initiating responses to infections or tissue damage. The nuclear factor-κB (NF-κB) pathway plays a key role in inflammation and innate immunity, as well as other cellular activities. Dysregulation of this well-choreographed pathway has been implicated in various diseases, including cancer. CARD11 is a key molecule in the BCL10-MALT1 complex, which is involved in transducing the signal downstream of the NF-κB pathway. This study aims to elucidate how CARD11 overexpression exacerbates the prognosis of colorectal cancer (CRC). To identify the cellular pathways influenced by CARD11, transcriptomic analysis in both CRC cell lines and patients was carried out on CARD11- overexpressed HCT-116 and HT-29 CRC cell lines alongside empty vector-transfected cell lines. Furthermore, a comparison of transcriptomic data from adenoma and carcinoma CRC patients with low- (CARD11-) and high-(CARD11+) CARD11 expression was carried out. Whole transcriptomics and bioinformatics analysis results indicate that CARD11 appears to play a key role in CRC progression. Absolute GSEA (absGSEA) on HCT-116 transcriptomics data revealed that CARD11 overexpression promotes cell growth and tissue remodeling and enhances immune response. Key genes co-expressed with CARD11, such as EP300, KDM5A, HIF1A, NFKBIZ, and DUSP1, were identified as mediators of these processes. In the HT-29 cell line, CARD11 overexpression activated pathways involved in chemotaxis and extracellular matrix (ECM) organization, marked by IL1RN, MDK, SPP1, and chemokines like CXCL1, CXCL3, and CCL22, which were shown to contribute to the more invasive stage of CRC. In patient samples, adenoma patients exhibited increased expression of genes associated with the tumor immune microenvironment, such as IL6ST, collagen family members, and CRC transition markers, such as GLI3 and PIEZO2, in CARD11+ adenoma patients. Carcinoma patients showed a dramatic increase in the expression of MAPK8IP2 in CARD11+ carcinoma patients alongside other cancer-related genes, including EMB, EPHB6, and CPEB4.

RESUMO

PURPOSE: To comprehensively assess the quality of life (QoL) of Egyptian university students. DESIGN: Cross-sectional online study. SETTING: Online settings of university students from August to October 2023. SUBJECTS: University students aged 18-25 from various institutions in Egypt. MEASURES: Physical, psychological, social, and environmental domains of the World Health Organization Quality of Life-BREF (WHOQOL-BREF) scale. Statistical analyses were performed using SPSS version 27.0. Mann-Whitney and Kruskal-Wallis tests were used to detect significant associations while Spearman correlation was used for correlation analysis. RESULTS: A total of 1930 Egyptian university students were included. Students showed outperformance in the psychological health and social relationships domains, with medians of 58 ± 20.8 and 58 ± 25, respectively, compared to physical health with a median of 46 ± 17.8 and environmental health with a median score of 16.6 ± 21.9. Non-medical students reported higher QoL scores, particularly in physical, psychological, and social domains, compared to their medical counterparts (P-values <0.001, 0.007, and 0.002, respectively). No significant differences were observed between genders in any of the domains. Academic performance satisfaction significantly correlated with higher QoL scores across all domains (P < 0.001). CONCLUSIONS: This multi-center study sheds light on diverse aspects influencing QoL of Egyptian university students. The findings underscore the importance of addressing academic stressors, promoting health behaviors, and tailoring interventions based on students' academic backgrounds with larger and more representative samples.

RESUMO

Objective: The purpose of this study was to investigate the technical feasibility of integrating the quantitative maps available from SyntheticMR into the head and neck adaptive radiation oncology workflow. While SyntheticMR has been investigated for diagnostic applications, no studies have investigated its feasibility and potential for MR-Simulation or MR-Linac workflow. Demonstrating the feasibility of using this technique will facilitate rapid quantitative biomarker extraction which can be leveraged to guide adaptive radiation therapy decision making. Approach: Two phantoms, two healthy volunteers, and one patient were scanned using SyntheticMR on the MR-Simulation and MR-Linac devices with scan times between four to six minutes. Images in phantoms and volunteers were conducted in a test/retest protocol. The correlation between measured and reference quantitative T1, T2, and PD values were determined across clinical ranges in the phantom. Distortion was also studied. Contours of head and neck organs-at-risk (OAR) were drawn and applied to extract T1, T2, and PD. These values were plotted against each other, clusters were computed, and their separability significance was determined to evaluate SyntheticMR for differentiating tumor and normal tissue. Main Results: The Lin's Concordance Correlation Coefficient between the measured and phantom reference values was above 0.98 for both the MR-Sim and MR-Linac. No significant levels of distortion were measured. The mean bias between the measured and phantom reference values across repeated scans was below 4% for T1, 7% for T2, and 4% for PD for both the MR-Sim and MR-Linac. For T1 vs. T2 and T1 vs. PD, the GTV contour exhibited perfect purity against neighboring OARs while being 0.7 for T2 vs. PD. All cluster significance levels between the GTV and the nearest OAR, the tongue, using the SigClust method was p < 0.001. Significance: The technical feasibility of SyntheticMR was confirmed. Application of this technique to the head and neck adaptive radiation therapy workflow can enrich the current quantitative biomarker landscape.

RESUMO

BACKGROUND: Many observational studies have examined the association between statins and the incidence of Parkinson's disease (PD) in high-risk populations. On the other hand, clinical trials as well as other observational studies investigated the safety and efficacy of statins in slowing disease progression in PD patients. However, the evidence has been inconclusive in both questions. To that end, we conducted this systematic review and meta-analysis to synthesize evidence on the role of statins in decreasing the risk of PD among high-risk populations and as a possible disease-modifying agent for patients with PD. METHODS: A comprehensive literature search of electronic databases including PubMed, Scopus, Cochrane, and Web of Science has been performed. Relevant studies were chosen and data were extracted and analyzed using RevMan software version 5.4.1. RESULTS: Twenty-five studies (14 cohort, 9 case-control, and 2 randomized controlled trials) have been included in the present systematic review. Of them, 21 studies reported the association between statins and PD risk. Statins were found to significantly reduce the risk of developing PD (pooled RR 0.86, 95% CI [0.77-0.95], p < 0.005). Four studies investigated statins as a disease-modifying agent. The pooled mean difference (MD) in the UPDRS-III from baseline to endpoint did not differ significantly between the statin and control groups (MD -1.34 points, 95% CI [-3.81 to 1.14], p = 0.29). CONCLUSION: Although epidemiological observational studies showed that statin use was associated with a reduced risk of PD, current evidence is insufficient to support the role of statins in slowing the progression of PD. These findings are limited by the fact that most of the included studies are observational studies which carry a high risk of confounding bias which highlights the need for future well-designed RCTs.

RESUMO

Background/Objectives: The use of miniplates for stabilizing bones post orthognathic surgery has surged in popularity due to their efficacy in ensuring stability and hastening recovery. However, controversy exists regarding what should be done with these miniplates after surgery. Some surgeons advocate for their removal, while others suggest leaving them in place. This study sought to assess the frequency, causes, and potential risk factors linked with miniplate removal in orthognathic procedures. Methods: A thorough meta-analysis was conducted by scrutinizing studies from various databases including PubMed, Google Scholar, Embase, and Scopus, focusing on publications spanning from 1989 to 2023. Results: Ten studies meeting the inclusion criteria, encompassing 1603 patients, were chosen for inclusion in the meta-analysis. The male-to-female ratio varied from 0.7:1 to 4:1. Overall, 5595 miniplates were inserted, with 294 (5.3%) being subsequently removed. Primary reasons for miniplate removal included infection (161 cases, 2.9%), exposure of miniplates (34 cases, 0.6%), and palpable plates (23 cases, 0.4%). Other indications comprised pain, patient preference, and temperature sensitivity. Less frequent causes for miniplate removal included sinusitis, secondary surgery, and dental pathology. The mean duration of miniplate removal was 5.5 months, with the majority (56.1%) being removed from the mandible rather than the maxilla. In conclusion, this meta-analysis underscores the importance of miniplate removal when hardware causes complications and physical discomfort. The primary reasons for removing miniplates were infection and plate exposure, with the mandible being the most common removal site. Conclusions: These findings emphasize the need for continued monitoring to assess the fate of miniplates in orthognathic surgery and provide valuable information for future clinical decision-making.

RESUMO

Introduction Despite the high level of patient satisfaction with functional endoscopic sinus surgery (FESS) and the clinical improvement, polyp recurrence is observed in 23% to 87% of patients and requires reoperation. Objective To assess the prognostic value of polypoid changes of the middle turbinate (PCMT) in relapse of paranasal sinus polyps in patients with chronic rhinosinusitis with nasal polyp (CRSwNP) after FESS and the effect of partial middle turbinectomy (PMT) on the outcome of surgery. Methods We conducted a prospective clinical study on 60 patients with CRSwNP with and without PCMT. The patients were allocated into three groups: group I included twenty patients without PCMT; group II, twenty patients with PCMT; and group III included twenty patients with PCMT submitted to PMT. The patients were evaluated endoscopically according to the Lund-Kennedy endoscopic scoring system, radiologically according to the Lund-Mackay scoring system, and symptomatically through the 22-item Sinonasal Outcome Test (SNOT-22). Results The total postoperative Lund-Kennedy score differed significantly among the 3 groups ( p < 0.001), with a group II presenting a significantly higher total score compared to groups I and III. The Preoperative SNOT-22 score differed significantly among the three groups ( p = 0.013), with group II presenting a significantly higher score compared to group I. There was a significant association involving the 3 groups and relapse at 12 months ( p = 0.029); relapse was higher in group II (50.0%) than in groups I (20%) and III (15.0%). Conclusion There was a significant association between PCMT and the relapse of nasal polyps. Also, nasal polyposis recurred at a lower rate in the group submitted to middle turbinate resection compared to the group in whom it was preserved.

RESUMO

PURPOSE: We aimed to evaluate the effect of cervical disc herniation (CDH) and lumbar disc herniation (LDH) on female sexual functioning before and after surgical intervention. METHODS: The current study was conducted from February 2022 to February 2023. A total of 100 sexually active female patients in their reproductive phase who were diagnosed with CDH and LDH based on physical examination and previous magnetic resonance imaging (MRI) results, as well as 50 healthy females, were enrolled. The female subjects were evaluated using the validated Arabic version of the female sexual function index (ArFSFI), a 0 to 10 visual analogue scale (VAS), the Oswestry disability index (ODI) and Beck's depression index (BDI). RESULTS: The baseline ArFSFI domains and total scores were greatest in the controls, followed by the CDH group. The ArFSFI domains and total scores were greatest in the control group, followed by the postoperative ArFSFI domains and total scores in the cervical group. The variations in satisfaction, pain, and overall ArFSFI ratings were significant across research groups. The difference in desire, arousal, lubrication, and orgasm was substantial in the lumbosacral group, but there were no significant changes between the cervical and control groups. Postoperatively, ArFSFI domains and overall scores improved in both of the cervical and lumbar groups. Both research groups' ODI score and grade improved after surgery. Finally, both groups' BDI score and grade improved after surgery. CONCLUSION: Female sexual dysfunctions caused by CDH and LDH improved considerably after surgery.

RESUMO

Acute severe ulcerative colitis (ASUC) is one of life-threatening complications that occur in one-fifth of ulcerative colitis (UC) patients with significant morbidity and an estimated mortality rate up to 1%. There are no validated clinical scoring systems for ASUC. Intravenous corticosteroids remain the cornerstone for the management of ASUC patients However, one-third of patients are steroid refractory and require colectomy in the pre-biologic era or salvage therapy in the post-biologic era. The currently available predictors of non-response to steroids and salvages therapy are sub-optimal. Furthermore, there is a need for the development of clear outcome measures for ASUC patients. Although infliximab and cyclosporin are both effective as salvage therapy, they still carry a rate of treatment failure. Hence, there is an unmet need to explore alternative therapeutic options before colectomy particularly in prior infliximab-exposed patients. This may include the introduction of small molecules with rapid onset of action as a salvage or sequential therapy and the use of slow-onset other biological therapy after "bridging" with cyclosporine. In this article, we explore the current best evidence-based practice and detail the gaps in knowledge in the management of ASUC.

RESUMO

BACKGROUND: Intraoral adenoid cystic carcinoma (ACC) arising from minor salivary glands (MSG) is a rare malignancy associated with delayed diagnosis and unfavorable outcomes. This study aimed to comprehensively review ACC of MSGs, focusing on clinical characteristics, imaging modalities, treatment approaches, and long-term outcomes. METHODS: A systematic search was conducted in PubMed, Web of Science, and MEDLINE databases to identify relevant articles reporting cases of ACC of MSGs between January 1997 and March 2023. The study was registered in PROSPERO (ID: CRD42023449478). A total of 10 studies that met the inclusion criteria were selected for critical review. In total, 902 patients were diagnosed with ACC of MSGs with an age range of 44.3 to 63 years, and an average age of 56.6 years. The female to male ratio ranges from 1:1 to 2.4:1. Regarding the primary site of ACC, the palate was the most common location, accounting for 30.5% to 83.3%, followed by the buccal mucosa, floor of the mouth, and lip and the retromolar area. For histology, the solid mass pattern was the most prevalent, seen in 95.2% of patients, followed by the cribriform pattern. Regarding treatment modalities, surgery was the most common approach, applied in 76.3% of cases, with a combination of surgery and radiotherapy used in 29.0% of cases. A smaller fraction, 3.2%, received a combination of surgery, chemotherapy, and radiotherapy, and 8.3% underwent radiotherapy alone. Local recurrence rates varied between 1% and 28.5%, and distant metastasis occurred in 18.2% to 33.3% of cases, predominantly to lymph nodes (14.5%). An analysis of overall survival across various stages and patient numbers indicated a 5-year survival rate of 68.0%. The findings of this study provide valuable insights for physicians in making treatment decisions and emphasize the need for ongoing research and collaborative clinical efforts to improve the management and outcomes of this challenging disease. CONCLUSION: ACC of MSGs is a multifaceted condition typically manifesting as asymptomatic enlargement and ulceration. This disease is marked by distinct histopathological patterns and perineural invasion (PNI). Recognizing these distinctive aspects is key in shaping the treatment plan, which can range from surgical procedures to radiation therapy, chemotherapy, and evolving targeted treatments. Continuous research and collaborative clinical efforts remain critical for ongoing progress in the treatment and management of this challenging condition.

RESUMO

PURPOSE: To compare outcomes of two different methods of meatoplasty following Canal Wall-Down tympanomastoidectomy. METHODS: A retrospective case review study of 48 patients with non-complicated unsafe chronic suppurative otitis media candidate for post-auricular canal wall-down tympanomastoidectomy via a post-auricular approach at Otolaryngology department, Benha university hospitals from January 2021 to January 2023, all were operated for the first time, and divided into 2 groups each of 24 patients. Group A submitted for classic 'Fisch', and group B 'Corner-Tag' meatoplasty. RESULTS: The mean age was 28.88 ± 13.26 years in group A and 33.33 ± 16.04 years in group B. Only one patient (4.2 %) in each group developed wound infection and none in both groups developed perichondritis. Two patients (8.3 %) in group B compared to only one patient (4.2 %) in group A had granulations on the meatal incision. One patient (4.2 % of group A) needed revision meatoplasty. Group B needed more time for epithelization (mean 7.33 ± 0.96 weeks) than group A (mean 6.5 ± 0.88 weeks; P = 0.003*) also resulted in wider mean new meatus in group B (mean 10.50 ± 1.02 mm) than in group A (mean 9.63 ± 1.41 mm; P = 0.02*). CONCLUSION: Both techniques had comparable post-operative complications. 'Corner-Tag' technique needed more time for healing and epithelization but gave a wider new meatal diameter than 'Fisch' meatoplasty after one year of follow-up.

RESUMO

BACKGROUND: Tamoxifen (TAM) is a chemotherapeutic drug widely utilized to treat breast cancer. On the other hand, it exerts deleterious cellular effects in clinical applications as an antineoplastic agent, such as liver damage and cirrhosis. TAM-induced hepatic toxicity is mainly attributed to oxidative stress and inflammation. Pioglitazone (PIO), a peroxisome proliferator-activated receptor-gamma (PPAR-γ) agonist, is utilized to treat diabetes mellitus type-2. PIO has been reported to exert anti-inflammatory and antioxidant effects in different tissues. This research assessed the impact of PIO against TAM-induced hepatic intoxication. METHODS: Rats received PIO (10 mg/kg) and TAM (45 mg/kg) orally for 10 days. RESULTS: TAM increased aspartate aminotransferase (AST) and alanine aminotransferase (ALT), triggered several histopathological alterations, NF-κB p65, increased hepatic oxidative stress, and pro-inflammatory cytokines. PIO protects against TAM-induced liver dysfunction, reduced malondialdehyde (MDA), and pro-inflammatory markers along with improved hepatic antioxidants. Moreover, PIO, increased hepatic Bcl-2 expression while reducing Bax expression and caspase-3 levels. In addition, PIO decreased Keap-1, Notch1, and Hes-1 while upregulated HO-1, Nrf2, and SIRT1. Molecular docking showed the binding affinity of PIO for Keap-1, NF-κB, and SIRT1. CONCLUSION: PIO mitigated TAM hepatotoxicity by decreasing apoptosis, inflammation, and oxidative stress. The protecting ability of PIO was accompanied by reducing Keap-1 and NF-κB and regulating Keap1/Nrf2/HO-1 and Sirt1/Notch1 signaling. A schematic diagram illustrating the protective effect of PIO against TAM hepatotoxicity. PIO prevented TAM-induced liver injury by regulating Nrf2/HO-1 and SIRT1/Notch1 signaling and mitigating oxidative stress, inflammation, and apoptosis.

RESUMO

BACKGROUND: Grade III brain arteriovenous malformation (AVM) is a distinct subgroup of AVMs that encompasses multiple subtypes according to the Spetzler-Martin classification. METHODS: This retrospective study included 61 patients with grade III AVM who underwent embolization between 2010 and 2022. The study analyzed the angioarchitecture of the AVM nidus and evaluated the outcomes of the embolization procedures. RESULTS: There were 29 patients (47.5%) with subtype S1E1V1, 20 patients (32.8%) with subtype S2E1V0, and 12 patients (19.7%) with subtype S2E0V1. The rate of complete occlusion in all patients was 47.5% (29 patients). The rate of complete occlusion was higher in cases with a compact nidus (P < 0.001). Several parameters were associated with occlusion of the AVM nidus, including ≤3 arterial feeders (P = 0.017) and presentation with hemorrhage (P = 0.007), with the majority of patients with a compact nidus presenting with hemorrhage. Other factors associated with compact geometry were the presence of a single deep vein, ≤3 arterial feeders, ≤2 superficial draining veins, and an AVM nidus size ≤3 cm. CONCLUSIONS: The compact nature of grade III AVM is a crucial predictor for the success of embolization. Several characteristics associated with a compact nidus, such as presentation with hemorrhage and a lower number of arterial feeders, have a significantly higher closure rate. Other factors, such as a single deep draining vein, reduced superficial venous drainage, and small size, show a strong association with complete obliteration.

RESUMO

Background: To examine the impact of aging on the response of rats to pentylenetetrazole (PTZ)-induction of epilepsy and the possible role of oxidative stress and nuclear factor erythroid 2-related factor 2 (Nrf2)/ heme oxygenase (HO)-1 pathway in this response. Methods: Forty male albino rats were equally allocated into 4 groups; 1) Young control (YC) group, aged 8-12 weeks, 2) Old control (OC) group, aged 24 months, 3) PTZ-Young group: young rats received PTZ (50 mg/Kg, i.p. every other day) for 2 weeks and 4) PTZ-Old group: as group 3 but rats were old. The seizure score stage and latency to the first jerk were recorded in rats. Redox state markers in brain tissues including malondialdehyde (MDA), catalase and total antioxidant capacity (TAC) were evaluated. Also, the expression of Nrf2 and HO-1 genes were measured in the brain tissues. Results: Old rats showed an early and a significant rise in the seizure score with PTZ administration and a significant drop in the seizure latency compared to young rats (P <0.01). Also, old rats showed a significantly higher MDA concentration and a significantly lower TAC and catalase activity than young rats (P <0.01). Moreover, the expression of Nrf2 and HO-1 was significantly lowered in old rats compared to young rats with PTZ administration (P < 0.01). Conclusion: Aging increases the vulnerability of rats to PTZ-induced epilepsy. An effect might come down to the up-regulation of oxidative stress and the down regulation of antioxidant pathways including Nrf2 and HO-1.

RESUMO

Malachite Green (MG) dye of the triphenylmethane group is a toxic compound used in the aquaculture industry as an antifungal agent, however, it can accumulate in fish and pose toxicity. The present work aims to remove MG in Microbial Fuel Cell (MFC) as a sustainable and eco-friendly solution. Out of six samples, the highest malachite green degradation was obtained by a sample obtained from Robiki tannery site in agar plates in 24 h at 37 °C. Robiki sample was used to inoculate the anodic chamber in Microbial Fuel cell, the resulting average electricity production was 195.76 mV for two weeks. The decolorization average was almost 88%. The predominant bacteria responsible for MG decolorization and electricity production were identified using 16S rRNA as Shewanella chilikensis strain MG22 (Accession no. OP795826) and formed a heavy biofilm on the anode. At the end of the decolorization process, MG was added again for re-use of water. The results showed efficiency for re-use 3 times. To ensure the sterility of treated water for re-use, both UV and filter sterilization were used, the latter proved more efficient. The obtained results are promising, MFC can be used as recirculating aquaculture system (RAS). The same aquaculture water can be treated multiple times which provides a sustainable solution for water conservation.

RESUMO

BACKGROUND: Cisplatin (CIS) is a chemotherapeutic agent widely used to cure several cancers. It exerts detrimental cellular effects that restrain its clinical application as an antineoplastic agent, as testicular damage. Pioglitazone (PIO), a peroxisome proliferator-activated receptor-gamma (PPAR-γ) agonist, is used to treat type-2 diabetes mellitus. PIO has been reported to exert anti-inflammatory and antioxidant effects in different tissues. The present study aimed to investigate the effect of PIO in a rat model of cisplatin-induced testicular toxicity and address the possible role of the Toll-like receptors (TLR4) / myeloid differentiation factor 88 (MyD88) / nuclear factor-kappa B (NF-kB) signal pathway. METHODS: Rats received a single dose of cisplatin (7 mg/kg, IP) on the first day and PIO (10 mg/kg, P.O.) for 7 days. At the end of the treatment period, rats were killed. Testicular weights, histopathological alterations, and serum testosterone levels were determined. Moreover, tissue samples were collected for the estimation of oxidative stress parameters, inflammatory markers, and the determination of TLR4 /MyD88/NF-kB signaling. RESULTS: Concurrent PIO administration with CIS markedly improved testicular weights, histopathological alteration, and serum testosterone level changes. Moreover, Concurrent PIO administration abrogated oxidative stress status and inflammatory markers caused by CIS administration. Furthermore, PIO inhibited the expression levels of TLR4, MyD88, and NF-κBp65, proteins that are activated by CIS administration. CONCLUSION: These findings suggested that PIO can protect against cisplatin-induced testicular toxicity in rats through inhibition of the TLR4 /MyD88/NF-kB signal pathway.

RESUMO

Key clinical message: It is important to consider foot and ankle tuberculosis (TB) as a potential cause of cystic lesion around the ankle, especially in patients with a history of TB. Early diagnosis and treatment with a rifampin-based regimen for a duration of 12 months can lead to good functional and clinical outcomes. Abstract: Skeletal TB is an uncommon accounting for 10% of extra-pulmonary TB may present slowly over an extended period of time, making a diagnosis difficult and time-consuming (Microbiology Spectr. 2017;5:5). For the best possible outcome and to reduce the risk of deformity diagnosis must be early (Foot (Edinb). 2018;37:105). For the treatment of drug-susceptible musculoskeletal illness, a rifampin-based regimen lasting 12 months is advised (Clin Infect Dis. 2016;63:e147; J Bone Joint Surg Br. 1993;75:240; Tubercle. 1986;67:243). A 33-year-old female who are working as nurse with diffuse, persistent and low in intensity ankle pain not aggravated relieved by analgesia and swelling over a period of 2 months, static not related to activity. With past medical history of partially treated pulmonary TB 1 year ago. She reported night sweats and low-grade fever during this period, and she denied any history of trauma. The right ankle was globally swollen and tender anteriorly and on the lateral malleolus. The skin over the ankle showed dark discoloration with cautery marks with no discharging sinuses. The range of motion of the right ankle was decreased. The plain x-ray of the right ankle showed three cystic lesion at the distal tibia, one cyst at the lateral malleolus and another one at the calcaneum. Surgical biopsy and expert gene test confirmed the diagnosis of tuberculous osteomyelitis. The patient was planned for surgical curettage of the lesion. After the confirmation of the diagnosis of TB with the biopsy and gene expert test, with consultation of senior chest physician the patient fitted to anti-tuberculous regimen. The patient had good functional and clinical outcome. This case report highlights the importance of considering skeletal TB as a potential cause of musculoskeletal symptoms, especially in patients with a history of TB. Early diagnosis and treatment with a rifampin-based regimen for a duration of 12 months can lead to good functional and clinical outcomes. Further research on the management and prevention of musculoskeletal TB is warranted to improve patient outcomes. The lesson behind this case is that the diagnosis TB osteomyelitis should be on the top of differential diagnosis of multiple cystic lesions around the foot and ankle especially in area where TB is endemic. Early diagnosis and early start of anti-tuberculous therapy can lead to full cure of the patient and in bad situation can minimize the complications.

RESUMO

Background Osteoarthritis of the ankle, which has a prevalence of 3.4% in the general population and affects 70% of candidates post-traumatically, is less common than hip or knee arthritis. Despite the recent progress in ankle arthroplasty surgery, ankle arthrodesis is still considered the gold-standard treatment for severe osteoarthritis of the ankle joint and can achieve impressive improvements in pain and function in the majority of patients. Our objective is to assess the clinical and functional outcomes of ankle arthrodesis, postoperative complications, and patient satisfaction. Methodology This was a descriptive cross-sectional study that took place at Future Hospital in Khartoum, Sudan, from July 2015 to July 2022. Our institute performed 102 ankle fusion surgeries; 14 patients were excluded from the study because they did not show up for their follow-up visit, meaning 88 candidates were included. Two cannulated screws (6.5 mm) were used for ankle fixation in all patients. The outcome was assessed two years after surgery. The American Orthopaedic Foot and Ankle Society (AOFAS) score was used to assess ankle function before surgery and two years after the procedure. Postoperative complications and patient satisfaction were reported. The primary researcher collected data through direct interviews. Result The mean age of the study participants was 52.2 years, with 36.4% being between 40 and 50 years of age. The study consisted of 43 women and 45 men. The male-to-female ratio was almost 1:1. In 56.8% of candidates, the right ankle was involved. The overall rate of complications was 11.4%. Concerning patient satisfaction, 75% of the patients were fully satisfied. Moreover, significant correlations were found between the mean postoperative AOFAS score and age group, diabetes mellitus, complications, and patient satisfaction. Conclusion Ankle arthrodesis was demonstrated to be an excellent surgical method for reducing pain and enhancing ankle joint function. The most frequent complications were delayed wound healing, infection, and non-union. The functional outcome and patient satisfaction of this procedure were statistically high; patients with a higher functional score had higher levels of satisfaction. In contrast, diabetic and elderly patients had higher rates of complications.

RESUMO

BACKGROUND: Diabetic nephropathy is a major cause of morbidity and mortality in type 1 diabetes mellitus (T1DM). Fatty acid binding proteins (FABP1 and FABP2) play a role in the development and progression of chronic kidney disease including type 2 diabetes mellitus. AIM: We assessed serum FABP1 and FABP2 levels in children and adolescents with T1DM as potential markers for diabetic nephropathy and their relation to carotid intima media thickness (CIMT). METHODS: Sixty patients with T1DM were divided into 2 groups according to the presence of nephropathy and compared with 30 healthy controls. CIMT, fasting blood glucose (FBG), hemoglobin A1c (HbA1c), urinary albumin creatinine ratio (UACR), fasting lipid profile and serum FABP1 and FABP2 levels were assessed. RESULTS: FABP1 and FABP2 levels were significantly higher among type 1 diabetic patient with and without nephropathy compared with healthy controls with the highest levels among patients with nephropathy (p < 0.001). There were significant positive correlations between FABP1 and FABP2 and each of systolic blood pressure, CIMT, FBG, HbA1c and total cholesterol among T1DM patients. FABP1 was negatively correlated to glomerular filtration rate. Multivariable linear regression analysis showed that systolic blood pressure, CIMT, FBG and HbA1c were the significant independent variables related to FABP1 levels in type 1 diabetic patients with nephropathy. ROC curve analysis was performed to determine the cutoff value of FABP1 and FABP2 that could detect nephropathy. CONCLUSION: FABP1 and FABP2 levels are elevated in children and adolescents with T1DM and could represent a link between diabetic nephropathy and subclinical atherosclerosis.

RESUMO

Despite significant advances in hepatobiliary surgery, biliary injury and leakage remain typical postoperative complications. Thus, a precise depiction of the intrahepatic biliary anatomy and anatomical variant is crucial in preoperative evaluation. This study aimed to evaluate the precision of 2D and 3D magnetic resonance cholangiopancreatography (MRCP) in exact mapping of intrahepatic biliary anatomy and its variants anatomically in subjects with normal liver using intraoperative cholangiography (IOC) as a reference standard. Thirty-five subjects with normal liver activity were imaged via IOC and 3D MRCP. The findings were compared and statistically analyzed. Type I was observed in 23 subjects using IOC and 22 using MRCP. Type II was evident in 4 subjects via IOC and 6 via MRCP. Type III was observed equally by both modalities (4 subjects). Both modalities observed type IV in 3 subjects. The unclassified type was observed in a single subject via IOC and was missed in 3D MRCP. Accurate detection by MRCP of intrahepatic biliary anatomy and its anatomical variants was made in 33 subjects out of 35, with an accuracy of 94.3% and a sensitivity of 100%. In the remaining two subjects, MRCP results provided a false-positive pattern of trifurcation. MRCP competently maps the standard biliary anatomy.
