Background Diffusion-tensor imaging (DTI) and fiber tractography are relatively recent MRI techniques that have opened an entirely new noninvasive window on the white matter (WM) connectivity of the human brain. Since their introduction, they have rapidly evolved and found application in essentially every disorder involving the WM. Aim The aim of this work was to study the clinical applications of DTI and fiber tractography in various neoplastic and nonneoplastic brain lesions, as well as to demonstrate their role in preoperative mapping of WM tracts in relation to brain lesions. Patients and methods A prospective study was conducted for 2 years on 40 patients presenting to Alexandria University with variable intracranial lesions related to WM tracts who underwent DTI and fiber tractography. The study included 25 males and 15 females. The age of the patients ranged from 6 to 76 years (mean age, 40.7 years). Qualitative analysis of DTI data was performed using directionally encoded color maps and three-dimensional tractography reconstruction. Results According to visual analysis multiple projection, association and/or commissural WM fiber tracts were involved; the most common was the corticospinal tract in 25 (62.5%) cases. WM tract involvement patterns were deviated/splayed tracts in 31 (64.6%) cases, infiltrated in nine (18.8%) cases, edematous in five (10.4%) cases, and interrupted in three (6.3%) cases. Conclusion DTI and fiber tractography are valuable noninvasive techniques providing qualitative information aiding in lesion characterization, determining WM integrity, and essential in the surgical planning for patients with intrinsic brain lesions.

Background Diabetes mellitus (DM) type 2 is a major health condition that has shown an increased incidence globally. The most common complication in type 2 DM is diabetic nephropathy (DN). Aim To determine serum galectin-3 as a prognostic biomarker in type 2 DN. Patients and methods A case–control prospective study was done in the Internal Medicine Department of AL-Zahraa University Hospital, Cairo, Egypt. The study was conducted on 90 patients, including 60 patients with type 2 DM and 30 age-matched and sex-matched healthy volunteers as a control group. The 90 patients were classified into four groups: group I included 20 diabetic patients (type 2) with an albumin/creatinine ratio (ACR) of less than 30 mg/g (normoalbuminuria), group II included 20 DM (type 2) with an ACR of 30–300 mg/g (microalbuminuria), group III included 20 DM (type 2) with an ACR of more than 300 mg/g (macroalbuminuria), and control group included 30 age-matched and sex-matched healthy individuals. History, examination, fasting blood sugar, glycated hemoglobin, urea, creatinine, estimated glomerular filtration rate, ACR, lipid profile, and serum galectin-3 were done for all participants. The study was approved by the Al Azhar University Ethics Board. Results Galectin-3 was significantly higher in patients with macroalbuminuria than in those with microalbuminuria and normoalbuminuria. Galectin-3 level has a significant positive correlation with parameters of DN progression (age, DM duration, fasting blood sugar, glycated hemoglobin, cholesterol, low-density lipoprotein, triglyceride, urea, creatinine, and ACR) and a significant negative correlation with estimated glomerular filtration rate and high-density lipoprotein levels. Conclusion Galectin-3 was significantly higher in type 2 diabetic patients with macroalbuminuria than in those with microalbuminuria and normoalbuminuria.

Background Lung cancer is the leading cause of cancer-related death. The accurate staging of lung cancer is important in determining the optimal treatment strategy and predicting the prognosis. Positron emission tomography (PET)/computed tomography (CT), which has the advantages of PET and CT and minimizes their limitations, is a potential tool for the staging of lung cancer. Objective This study aimed to evaluate the role of PET/CT in the staging of lung cancer. Patients and methods This study was carried out on 40 patients with pathologically confirmed lung cancer referred to the Nuclear Medicine Unit affiliated to the Department of Radiodiagnosis at Sharq El Madina Hospital, Ministry of Health, Alexandria, between November 2017 and December 2019 for initial staging of lung cancer with PET/CT or restaging after therapy. Combined PET/CT imaging was performed using the Siemens biograph 64 PET/CT scanner. Results (a) Initial staging: PET/CT was able to assess the stage of ten patients (25%), whose stage could not be assessed by CECT. Both PET/CT and CECT disagreed in the staging of six patients. PET/CT staged 10 (25%) patients that could not be assessed by contrast enhanced computed tomography (CECT) and they disagreed in staging of six patients (15%). T staging was predicted by PET/CT in the 40 patients (100%) and by CECT in 30 patients (75%), with disagreement in two patients (5%). PET/CT disagreed with CECT in N staging of 10 patients (25%). PET/CT detected distant metastasis (M) in 18 patients (45%), while CECT detected it in 14 patients (35%). (b) Restaging after neoadjuvant therapy: staging was concordant in six out of eight patients (75%) and dissimilar in two patients (25%). Conclusion PET/CT is an essential component in the initial staging of lung cancer for its better locoregional and distant staging abilities. It is also more reliable in restaging after neoadjuvant therapy, being more related to the functional activity of the residual tumor rather than its size.
肺癌是癌症相关死亡的主要原因。准确的肺癌分期对确定最佳治疗方案和预测预后具有重要意义。正电子发射断层扫描(PET)/计算机断层扫描(CT)具有PET和CT的优点，最大限度地减少了它们的局限性，是肺癌分期的潜在工具。目的探讨PET/CT在肺癌分期中的作用。患者和方法本研究于2017年11月至2019年12月期间在亚历山大卫生部Sharq El Madina医院放射诊断科附属核医学部门进行的40例病理证实的肺癌患者进行了研究，这些患者通过PET/CT进行肺癌初始分期或治疗后重新分期。PET/CT联合成像采用Siemens biograph 64 PET/CT扫描仪。(a)初始分期:PET/CT能够评估10例(25%)患者的分期，这些患者的分期不能被CECT评估。PET/CT和CECT对6例患者的分期不一致。PET/CT对10例(25%)不能通过增强计算机断层扫描(CECT)评估的患者进行分期，对6例(15%)患者的分期不一致。40例(100%)患者通过PET/CT预测T分期，30例(75%)患者通过CECT预测T分期，2例(5%)患者不一致。10例(25%)患者的N分期PET/CT与CECT不一致。PET/CT检出远处转移(M) 18例(45%)，CECT检出远处转移14例(35%)。(b)新辅助治疗后再分期:8例患者中有6例(75%)分期一致，2例(25%)分期不一致。结论PET/CT具有较好的局部和远处分期能力，是肺癌早期分期的重要组成部分。它在新辅助治疗后的再分期中也更可靠，更多地与残余肿瘤的功能活性有关，而不是其大小。

Background There is an increased risk of developing venous thromboembolism in patients with severe acute respiratory syndrome coronavirus disease (SARS COVID-19). As the D-dimer could be elevated in deep venous thrombosis (DVT), we aimed to investigate the incidence of DVT in patients with SARS COVID-19 and elevated plasma levels of the D-dimer. Patients and methods A prospective observational study was carried out to screen all patients with a confirmed diagnosis of SARS COVID-19 with plasma D-dimer levels above 1000 ng/ml for the presence of DVT without related symptoms using complete compression Doppler ultrasound. Results A total of 52 patients were included in the study. Among them, 34 (67.3%) were males. All patients received standardized thromboprophylaxis treatment. The screening results of complete compression Doppler ultrasound revealed DVT in eight (15.4%) patients. Among these patients, the DVT was proximal in one (1.9%) patient and bilateral distal in two (3.8%) patients. The D-dimer level was significantly higher in patients with DVT than in patients without DVT (4531 vs. 2048 ng/ml, odds ratio 9.4, 95% confidence interval 1.2–70.3). The diagnostic ability of the D-dimer was satisfactory, with an receiver operating characteristic curve of 0.71 (95% confidence interval 0.62–0.83). Conclusion The incidence of DVT without symptoms in patients with SARS COVID-19 and elevated plasma level of D-dimer was 15.4%, with a significant difference between patients with and without DVT in terms of the D-dimer. Therefore, the D-dimer is important for the diagnosis of DVT in patients with SARS COVID-19.

Background Acne scarring remains a challenge to treat. Both botulinum toxin type A (BTX-A) and carboxytherapy (CXT) are considered novel treatment modalities for acne scars. Aim This study aimed to compare the efficacy and safety of BTX-A versus CXT in the treatment of postacne scars. Patients and methods Forty patients aged 18–50 years, with mild to severe postacne scars, were enrolled in this study and were divided randomly and equally into two groups: group A included 20 patients who underwent three sessions of an intralesional injection into postacne scars by BTX-A at a 3-week interval and group B included 20 patients who underwent three sessions of CXT on postacne scars at a 3-week interval. Evaluation of the clinical response to treatment was performed every 3 weeks and 1 month after the last session by photos and the global scarring grading system and patient satisfaction was assessed. Results There was a significant improvement in the degree of scar severity before and after treatment in both groups. There was no significant difference between improvements in both groups, indicating that both modalities of treatment yielded similar net results. Conclusion Both BTX-A and CXT can be effective and safe therapeutic options for the treatment of postacne scars with no significant side effects.

Background Diffusion-weighted imaging (DWI) is reliable in diagnosing intracranial cysts. However, sometimes, it could not give satisfactory diagnostic confidence. Objective To study the role of DWI in differentiation between intracranial cysts and the usefulness of apparent diffusion coefficient. Patients and methods This study included 40 patients of different age groups with intracranial cysts. All patients included were subjected to full history taking, clinical examination, laboratory investigations, routine MRI examination, DWI, and apparent diffusion coefficient map. Results Receiver operating characteristic curve was generated to identify inflammatory intra-axial lesions and to obtain the best sensitivity (80%), specificity (83.3%), positive predictive value (80%), and negative predictive value (83.3%). The relationship was significant (P<0.028). Receiver operating characteristic curve to identify epidermoid and arachnoid cysts and to obtain the best sensitivity (100%), specificity (100%), positive predictive value (100%), and negative predictive value (100%). The relationship was significant (P=0.013). Conclusion DWI is perfect in differentiating between necrotic tumors and abscesses, benign and malignant intracranial cysts, and between arachnoid and epidermoid cysts. But it failed in differentiating between lower-grade and high-grade glioma.

Background Diabetes mellitus (DM) is a complex metabolic disorder, and its rapid emergence worldwide has led to its classification as an epidemic. Aim To increase our knowledge about omentin-1 and its relation with type 2 DM, insulin resistance, and obesity. Patients and methods This study included 50 patients with type 2 DM, with an age range from 40 to 70 years, who were divided into two groups (25 obese and 25 nonobese), as well as 40 age group (20 obese and 20 nonobese)-matched patients, who formed the control group. Each group was subjected to full history taking and clinical examination (fasting blood glucose, total cholesterol, triglycerides, low-density lipoprotein-cholesterol, glycosylated hemoglobin, fasting insulin, and serum omentin-1 levels). Weight and height were measured. Homeostasis model assessment insulin resistance and BMI were calculated. Results The study showed a significant decrease in serum omentin-1 levels in type 2 diabetic patients in comparison with the control group. Serum omentin-1 levels inversely correlated with obesity, insulin resistance, and systolic blood pressure. Negative associations were found between serum omentin-1 level and fasting glucose, glycosylated hemoglobin, and fasting lipid levels. Conclusion Omentin-1 may be used as a biomarker for obesity and associated metabolic and vascular disorders.

Background Keratoconus is an ectatic corneal disorder characterized by progressive corneal thinning that results in corneal protrusion, irregular astigmatism, and decreased vision. Objective To evaluate changes in corneal density following corneal cross-linking (CXL) in keratoconic patients. Patients and methods This was a prospective case series study including all patients with keratoconus (50 eyes) undergoing CXL. The number of male patients in the study was 13 (26 eyes) cases, while female patients represented 12 (24 eyes) cases; the study was conducted at the outpatient clinic of the Ophthalmology Department at Al Azhar University Hospital. Results There was no statistically significant correlation between corneal densitometry and K1, K2, K-max, or thinnest corneal thickness preoperatively. There was no statistically significant correlation between corneal densitometry and K1, K2, K-max or thinnest corneal thickness at 1 month postoperatively. There was no statistically significant correlation between corneal densitometry and K1, K-max, or thinnest corneal thickness at 3 months postoperatively. Also, the table shows that there was statistically significant positive correlation between corneal densitometry and K2 with P value of 0.037 and r=0.296. There was no statistically significant correlation between corneal densitometry and K1, K2, K-max, or thinnest corneal thickness at 6 months postoperatively. Conclusion After CXL, the Scheimpflug corneal densitometry and clinical corneal haze peaked at 1 month followed by a gradual decline reaching baseline by 6 months after operation. Corneal thinning was correlated inversely with the corneal haze at 1 month postoperatively. Lens densitometry was not affected by CXL.

Background In addition to the physical deformity, there is often great psychological trauma due to facial scars among patients. Fat grafting in its various forms could be considered as a hallmark in scar rejuvenation therapy in the twenty-first century. This is due to the viable adipose-derived stem cells present in the nanofat. Objective The aim of this study was to evaluate the effect of nanofat grafting on postburn and post-traumatic facial scars using a standardized and validated scale [patient observer scar assessment scale (POSAS)] and photographs. Materials and methods A total of 20 patients with facial scars (10 patients post-traumatic and 10 patients postburn) were studied. Preoperative scoring of the scars was performed with the POSAS, and photographs were taken. Fat aspiration was performed from the lower abdomen and thighs using syringe liposuction under tumescent anesthesia. The lipoaspirate was mechanically emulsified, filtered, and injected intralesionally into the scar using a 27 G needle. Postoperative scar reassessment was performed at 3 months using the POSAS scale and photographs. The improvements in scar characteristics and symptoms were tested statistically. Results On statistical analysis, there was a statistically significant improvement in symptoms such as pain, itching, stiffness, thickness and irregularity and scar characteristics such as vascularity, relief, pliability, thickness, and pigmentation 3 months after injection. The photographic comparison also showed good anesthetic outcome. Conclusion Autologous emulsified nanofat injection is effective in improving the scar characteristics as well as symptoms and aiding in scar rejuvenation.

Background Minimal invasion surgeries have gained popularity in many fields of ophthalmology. In strabismus surgery, a similar approach is done to gain access to muscles, which is performed through keyhole openings. Objective To compare between minimal invasive strabismus surgery (MISS) technique and limbal approach for horizontal rectus muscle regarding postoperative muscular alignment and postoperative complications. Patients and methods This study included 60 eyes (36 patients of different age and sex) presenting with horizontal strabismus. The first group included 30 eyes that were managed by MISS (patient group), and the second group included 30 eyes that were managed by the limbal approach (control group). Results No significant difference was found regarding postoperative pain, conjunctival redness, and ocular alignment. There was no significant increase in complications between the two groups. Operative time was longer in the MISS technique, with highly significant difference between the two groups. Conclusion MISS technique is an alternative technique to limbal incision that can be used on horizontal muscles. It has the same effect as the limbal approach with the same success rate. It has the advantages of sparing perilimbal episcleral vessels, which make some surgeon prefer it if there is fear of anterior segment ischemia.
