Does Primary Cleft Palate Repair by Furlow Z-Plasty Technique With a Buccinator Myomucosal Flap Change Speech and Middle Ear Outcomes?

BACKGROUND: Children with repaired cleft lip and palate may present with middle ear effusion and disturbed speech due to velopharyngeal (VP) insufficiency. Furlow Z-palatoplasty with a buccinator myomucosal flap is one of the effective surgical techniques for primary cleft palate repair and lengthening of the palate. PURPOSE OF THE STUDY: This study aimed to evaluate the effect of Furlow Z-palatoplasty with buccal myomucosal flap as a primary cleft palate repair technique on the VP function during speech and the Eustachian tube function. MATERIALS AND METHODS: Forty patients with non-syndromic cleft lip and palate aged 3 to 7 years surgically repaired with Furlow palatoplasty with a buccinator myomucosal flap were assessed. Perceptual speech assessment, nasopharyngoscopic examination, otoscopic examination, and tympanometry were done for all patients to assess the speech and middle ear function. RESULTS: The percentage of mild hypernasality was significant in 22.5% of children with repaired cleft lip and palate, while 77.5% showed no hypernasality. Speech intelligibility was normal in 77.5% and mildly affected in 22.5% of children with repaired cleft palate. Compensatory misarticulations were recorded in 12.5% of children. Nasopharyngoscopic examination revealed adequate VP closure in 75% of children with repaired cleft palate. Twenty-five percent of children with repaired cleft lip and palate had middle ear effusion and required myringotomy with insertion of tympanostomy tubes. CONCLUSION: Primary cleft palate repair with Furlow Z-palatoplasty with buccal myomucosal flap had beneficial effects on speech outcomes. It was associated with a low prevalence of middle ear effusion, and a low number of tympanostomy tubes were needed.

Evaluation of Vermillion Symmetry and Scar Quality in Unilateral Cleft Lip Repair Using Modified Millard's Technique Versus Fisher's Technique.

BACKGROUND: Since the primary goal of cleft lip repair is to achieve a symmetrical, aesthetic lip, several surgical techniques have been utilized. Accordingly, in this study, a unilateral cleft lip was surgically repaired using two techniques: modified Millard's and Fisher's techniques. PURPOSE: This study was designed to compare the vermillion symmetry and scar quality in the surgical management of patients with unilateral incomplete cleft lip using the modified Millard's and Fisher's techniques. STUDY DESIGN, SETTING, AND SAMPLE: We conducted a prospective randomized controlled clinical study. The study involved 20 patients selected from the Department of Plastic Pediatric Surgery at the Specialized Pediatric Hospital, Faculty of Medicine, Cairo University. The patients included in the study were aged between 2 and 6 months old, had a primary nonsyndromic unilateral incomplete cleft lip, and had no other associated anomalies. PREDICTOR VARIABLE: The predictor variable was operative management of the cleft lip, and subjects were randomly assigned to either the modified Millard or Fisher techniques. MAIN OUTCOME VARIABLES: The primary outcome, vermillion symmetry, was evaluated by computerized photogrammetric lip analysis with Image J software. Additionally, scar quality, considered a secondary outcome, was assessed with the Vancouver Scar Scale and the Image J software. Every measurement was meticulously recorded in millimeters. COVARIATES: Age, sex, and cleft side were considered. ANALYSES: Descriptive and analytic statistics were computed. Statistical significance was set at P < .05. RESULTS: The study comprised 20 children (12 males and 8 females), with a mean age of 140.5 ± 23.7 days in the Fisher's group and 137.4 ± 25.6 days in the modified Millard's group (P = .8). No statistically significant differences (P = .6) were found in vermillion height and width between both groups at 1 week, 3 months, and 6 months. Similarly, there were no statistically significant differences (P = .4) between both groups in terms of scar length and width at the 3- and 6-month follow-up periods. CONCLUSION AND RELEVANCE: This study found no statistically significant differences in vermillion symmetry and scar quality between the two cleft lip repair techniques. Notably, one patient in the modified Millard group exhibited a notch on the vermillion border, which was not statistically significant.

Effectiveness of secondary furlow palatoplasty with buccal myomucosal flap in correction of velopharyngeal insufficiency in patients with cleft palate.

OBJECTIVES: The main purpose of this study was evaluation of the effectiveness of secondary furlow palatoplasty with buccal myomucosal flap (FPBF) for the treatment of velopharyngeal insufficiency (VPI) in patients with a cleft palate who were treated with two flap palatoplasty (TFP) in their primary palate repair. MATERIAL AND METHODS: Twenty-three medically free children aged 4-8 years with non-syndromic and previously repaired cleft palate via TFP participated in the study. All patients received secondary surgery following the technique of FPBF. Preoperative speech evaluation was done before the secondary repair and 3 months after the surgery using a hypernasal speech scale, speech intelligibility scale, and nasopharyngoscopy. RESULTS: A statistically significant improvement was observed regarding the degree of hypernasality and speech intelligibility while comparing the preoperative scores after the primary surgery to the postoperative scores after the secondary surgery. In addition, a statistically significant improvement was found in the nasopharyngoscopic assessment. CONCLUSIONS: The incorporation of a buccal myomucosal flap with Furlow palatoplasty was successful in improving hypernasality, speech intelligibility, and nasopharyngoscopic scores in patients with cleft palate. TRIAL REGISTRATION: clinicaltrials.gov (NCT05626933). CLINICAL RELEVANCE: This technique might be the surgical technique of choice while treating patients who are suffering from VPI after cleft palate repair.

Acquired Multidrug Resistance in AML Is Caused by Low Apoptotic Priming in Relapsed Myeloblasts.

In many cancers, mortality is associated with the emergence of relapse with multidrug resistance (MDR). Thus far, the investigation of cancer relapse mechanisms has largely focused on acquired genetic mutations. Using acute myeloid leukemia (AML) patient-derived xenografts (PDX), we systematically elucidated a basis of MDR and identified drug sensitivity in relapsed AML. We derived pharmacologic sensitivity for 22 AML PDX models using dynamic BH3 profiling (DBP), together with genomics and transcriptomics. Using in vivo acquired resistant PDXs, we found that resistance to unrelated, narrowly targeted agents in distinct PDXs was accompanied by broad resistance to drugs with disparate mechanisms. Moreover, baseline mitochondrial apoptotic priming was consistently reduced regardless of the class of drug-inducing selection. By applying DBP, we identified drugs showing effective in vivo activity in resistant models. This study implies evasion of apoptosis drives drug resistance and demonstrates the feasibility of the DBP approach to identify active drugs for patients with relapsed AML. SIGNIFICANCE: Acquired resistance to targeted therapy remains challenging in AML. We found that reduction in mitochondrial priming and common transcriptomic signatures was a conserved mechanism of acquired resistance across different drug classes in vivo. Drugs active in vivo can be identified even in the multidrug resistant state by DBP.

Effects of two flap palatoplasty versus furlow palatoplasty with buccal myomucosal flap on maxillary arch dimensions in patients with cleft palate at the primary dentition stage: a cohort study.

OBJECTIVE: The objective of this study was to evaluate the effect of two flap palatoplasty (TFP) versus Furlow palatoplasty with buccal myomucosal flap (FPBF) on maxillary arch dimensions in children at the primary dentition stage with cleft palate, in comparison to matching subjects without any craniofacial anomalies. MATERIAL AND METHODS: This study included 28 subjects with an age range of 5-6 years; 10 non-cleft subjects were included in the control group, 9 patients treated with TFP, and 9 patients treated with FPBF. For the included patients, the maxillary models were scanned using a desktop scanner to produce virtual models, and the maxillary dimension measurements were virtually completed. The produced measurements were compared between the 3 groups. Maxillary models of the 28 participants were evaluated. RESULTS: Statistically insignificant differences were detected between the 3 groups for arch symmetry measurements. Differences were detected in the inter-canine width between the 2 surgical groups and non-cleft group. Both arch length and posterior palatal depth significantly differ while comparing the TFP to the control group, with no differences between FPBF and the non-cleft group. CONCLUSION: Furlow palatoplasty with buccal myomucosal flap might be considered a better surgical option than two flap palatoplasty for patients with cleft palate while evaluating maxillary arch dimensions at the primary dentition stage as a surgical outcome. CLINICAL RELEVANCE: This study gives insight into the surgical technique that has limited effect on the maxillary growth and dental arch dimension. Therefore, it decreases the need for orthodontic treatment and orthognathic surgery. TRIAL REGISTRATION: clinicaltrials.gov ( NCT05405738 ).

Diagnostic Accuracy of Placental Thickness in Lower Uterine Segment Measured by Ultrasound in Prediction of Placenta Accreta Spectrum in Patients with Placenta Previa. A Diagnostic Test Accuracy Study.

Objective: The aim of the study was to evaluate the association between placental thickness and placenta accreta spectrum (PAS) in patients with placenta previa. Materials and Methods: In this prospective study, 40 patients diagnosed with placenta previa were included. The maximum placental thickness in the lower uterine segment was obtained using a transabdominal scan. For the image to be deemed suitable, a midline sagittal section of the lower uterine segment (with the implanted placenta) and the cervical canal, with the intervening urinary bladder had been required. Intraoperative attendance was ensured for the detection of cases with spontaneous separation and cases with morbid adherence. All specimens removed were sent for histopathology to confirm PAS. The primary outcome of the study was to detect a threshold of placental thickness which can be used as a cut-off value in such screening test. The number of units of packed RBCs transfused during the operation and bladder injury were secondary measures of outcome. Results: Forty patients were included in the study; 20 patients were ultimately diagnosed with PAS while 20 patients did not have PAS. Mean placental thickness was significantly higher in the PAS patients compared with those with no invasive placentation (61.00 mm Vs 43.00 mm, P value 0.000). Using receiver operating characteristic (ROC) curve, a threshold placental thickness of 58mm was associated with 55% sensitivity, 90% specificity, 84.6% positive predictive value, and 66.7% negative predictive value. Multivariate logistic regression showed that placental thickness more than 58mm and having past history of more than three cesarean sections were independent risk factors for PAS among patients with placenta previa. Conclusion: Placental thickness in the lower uterine segment is increased in patients with placenta previa with PAS compared to those with no PAS. Such finding can be implemented into clinical practice by using placental thickness as a screening test for PAS in patients with placenta previa. ClinicalTrialsgov ID: NCT05500404.

The impact of metformin use on the outcomes of locally advanced breast cancer patients receiving neoadjuvant chemotherapy: an open-labelled randomized controlled trial.

Recently, several clinical trials have attempted to find evidence that supports the anticancer use of metformin in breast cancer (BC) patients. The current study evaluates the anticancer activity of metformin in addition to neoadjuvant chemotherapy (NACT) in locally advanced BC patients. Additionally, we assess the safety and tolerability of this combination and its effect on the quality of life (QoL) of BC patients. Eighty non-diabetic female patients with proven locally advanced BC were randomized into two arms. The first arm received anthracycline/taxane-based NACT plus metformin. The second arm received anthracycline/taxane-based NACT only. Overall response rate (ORR), clinical complete response (cCr), pathological complete response (pCR), and breast conservative rate (BCR) were evaluated between both groups, and correlated with serum metformin concentration. ORR, cCr, pCR, and BCR increased non-significantly in the metformin group compared to the control group; 80.6% vs 68.4%, 27.8% vs 10.5%, 22.2% vs 10.5%, and 19.4% vs 13.2%, respectively. A trend towards cCR and pCR was associated with higher serum metformin concentrations. Metformin decreased the incidence of peripheral neuropathy, bone pain, and arthralgia, although worsened the gastrointestinal adverse events. Metformin combination with NACT has no effect on the QoL of BC patients. Metformin combination with NACT is safe, tolerable, and improves non-significantly the clinical and pathological tumor response of BC patients.

Factors influencing the anticancer effects of metformin on breast cancer outcomes: a systematic review and meta-analysis.

INTRODUCTION: Several clinical trials have attempted to find evidence that supports the use of metformin as an anticancer treatment. However, the observed effects on various breast cancer (BC) outcomes have been heterogeneous. AREAS COVERED: Based on the outcomes of previous clinical trials, this review discusses the patients' characteristics, cancer intrinsic subtypes, cancer stage, and anticancer treatments that may influence the anticancer effect of metformin on BC outcomes. Additionally, the safety and tolerability of metformin addition to various anticancer regimens are reviewed. EXPERT OPINION: Metformin is a challenging anticancer agent in BC cohorts, besides being safe and well-tolerated at antidiabetic doses. Survival benefits of metformin have been observed in BC patients with: hormone receptor-positive, human epidermal growth factor receptor-2 overexpression, and high insulin like growth factor-1 receptor expression on the tumor surface. Moreover, patients with diabetes receiving metformin experienced better survival outcomes compared to diabetic patients not receiving metformin. Additionally, metformin has anti-proliferative activity in patients with BC who have high insulin resistance and high body mass index. Besides, metformin has been shown to decrease metastatic events, and enhance the level of metabolic- and insulin-related biomarkers associated with carcinogenesis. Finally, most adverse events following metformin treatment were low-grade GIT toxicities.

Comparative efficacy of lidocaine-prilocaine cream and vaginal misoprostol in reducing pain during levonorgestrel intrauterine device insertion in women delivered only by cesarean delivery: A randomized controlled trial.

OBJECTIVE: To compare efficacy of lidocaine-prilocaine (LP) cream versus misoprostol versus placebo before levonorgestrel-releasing intrauterine device (LNG-IUD) insertion. METHODS: This randomized controlled trial (RCT) was conducted in a tertiary referral hospital from April 30, 2020 to March 1, 2021 on 210 parous women willing to receive LNG-IUD and delivered only by elective cesarean delivery (CD). Participants received 200 µg vaginal misoprostol or 5 ml of LP cream 5% or placebo 3 h before LNG-IUS insertion. Primary outcome was pain during LNG-IUD insertion, while secondary outcomes were pain 10 min post-procedure, ease of insertion, patient satisfaction, insertion time, and drug side effects. RESULTS: Pain during LNG-IUS insertion was reduced in LP group and misoprostol group compared to placebo group (2.1 ± 1.0 vs 3.7 ± 1.6; p <0.001) and (2.3 ± 1.3 vs 3.7 ± 1.6; p <0.001), respectively. Ease of procedure and patient satisfaction were significantly higher in LP and misoprostol groups than placebo (P <0.001). Need for additional analgesia was significantly higher in placebo group than in the other two groups (P = 0.009). Adverse events were not significantly different between the three groups except vomiting and abdominal cramps, which were higher with misoprostol. CONCLUSION: LP cream and 200 µg of vaginal misoprostol administration before LNG-IUD insertion in women delivered only by elective CD effectively reduced pain during insertion and 10 min post-procedure with easier insertions, high patient satisfaction, and tolerable side effects. Pain reduction with LP cream was clinically significant.

Quantitative Evaluation of Palatal Lengthening After Cleft Palate Repair When a Buccal Flap Is Routinely Combined With Furlow's Z-Plasty.

INTRODUCTION: The use of a buccinator myomucosal flap in combination with Furlow's Z-plasty during primary and secondary palatal repairs has been proposed by many authors to overcome some of the limitations of Furlow's technique. However, there have been no studies that quantitatively measured the effective palatal lengthening when the buccal flap is added. PATIENTS AND METHODS: The buccal flap is routinely used during primary palate repair in order to fill the gap between the hard palate and reoriented palatal muscle sling. The soft palatal length was measured in the midline from the posterior edge of the hard palate to the base of the uvula. All patients were measured before starting the surgery and just after palatal closure in the standard position for cleft palate repair. RESULTS: Seventy-three patients with cleft palate who were candidates for primary repair were included. The mean age at the time of operation was 11.4 ± 3.5 months. The mean preoperative palatal length was 21.36 ± 3.529 mm, whereas the mean postoperative palatal length was 29.64 ± 4.171) mm. The mean palatal length change was 8.29 ± 2.514 mm (P < 0.000). CONCLUSIONS: The Combined use of a buccinator myomucosal flap with modified Furlow's Z-plasty in primary cleft palate repair has proven effective for palatal lengthening and achieved tensionless closure without the need for relaxing incision. It also provided a pliable soft tissue attachment of the palatal muscles to the hard palate allowing for better muscle function and mobility.

Patient-specific PEEK implants for immediate restoration of temporal fossa after maxillary reconstruction with temporalis muscle flap / 대한악안면성형재건외과학회지

Background@#Temporal hollowing is a common complication following the rotation of the temporalis muscle that leaves the patient with a cosmetic impairment. Several alloplastic materials have been used to reconstruct the donor site; however, these implants need meticulous adaptation to conform the periphery of the defect and restore the contour of the temporal area. The aim of this study was to assess the use of patient-specific polyetheretherketone (PEEK) temporal implants to prevent temporal hollowing following the use of full temporalis muscle flap for large maxillary defects reconstruction. @*Methods@#This was a prospective study conducted on eight patients with major maxillary defects indicating the need of reconstruction with full temporalis muscle flap or any lesion indicating major maxillary resection and immediate reconstruction with total temporalis muscle flap. For each patient, a patient-specific PEEK implant was fabricated using virtual planning and milled from PEEK blocks. In the surgical theater, the temporalis muscle was exposed, elevated, and transferred to the maxilla. After the temporalis muscle transfer, PEEK implants were fixed in place to prevent temporal hollowing. @*Results@#The surgical procedures were uneventful for all patients. The esthetic result was satisfactory with no post-operative complications except in one patient where seroma occurred after 2 weeks and resolved after serial aspiration. @*Conclusion@#Patient-specific PEEK implant appears to facilitate the surgical procedures eliminate several meticulous steps that are mainly based on the surgeon’s experience.

In-vitro and in-vivo investigation of amygdalin, metformin, and combination of both against doxorubicin on hepatocellular carcinoma.

AIM: Hepatocellular carcinoma (HCC) is a potentially life-threatening cancer. In the current study, anti-HCC efficacy of amygdalin, or metformin alone or in combination in comparison to doxorubicin was studied. MAIN METHODS: Both in-vitro and in-vivo based models. HepG-2 and Huh-7 cell lines as established in-vitro model for HCC were treated with different concentrations of indicated drugs to evaluate the cytotoxicity and determine IC50 for 24, 48 and 72 h. Moreover, the effect of different treatments on apoptosis and cell cycle using flow cytometric analysis were studied. Hepatocellular carcinoma induced in rats by diethyl-nitrosamine and carbon tetrachloride was established, to further investigate the efficacy of indicated drugs. Aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase were measured by spectrophotometer, alpha-fetoprotein, cytochrome-c, caspase-3 and malondialdehyde were measured by ELISA, and liver biopsies were also evaluated histopathologically. KEY FINDINGS: In-vitro results showed that the combination has a promising effect when compared to amygdalin or metformin alone as it is more cytotoxic and have higher ability for induction of apoptosis and arresting cell cycle. In-vivo doxorubicin has a good effect for treating HCC. Also, the combination showed a promising prognostic effect depending on the cytotoxic activity and tumor marker when compared to amygdalin or metformin alone. SIGNIFICANCE: Based on the current data, it was hypothesized that amygdalin and metformin especially when used in combination will be a promising approach with low side effects for enhancement of HCC.

Three-Dimensional Echocardiography in Evaluating LA Volumes and Functions in Diabetic Normotensive Patients without Symptomatic Cardiovascular Disease.

BACKGROUND: Cardiovascular complications are the most serious threat to diabetic patients. Associated metabolic and microvascular changes are the main cause of cardiac function affection, and the earliest cardiac change is diastolic dysfunction. Assessment of LA function changes is a key to determine early heart damage of diabetic patients. OBJECTIVES: To evaluate the effect of diabetes mellitus on left atrial volumes and functions by using real-time 3-dimensional echocardiography in normotensive patients free from cardiovascular disease. METHODS: The study included 110 individuals, 50 controls and 60 patients with diabetes mellitus, 30 patients with type 1 diabetes mellitus and 30 patients with type 2 diabetes mellitus. 2-dimensional echocardiography was used to assess the LA maximum volume and LA phasic volumes, and LA maximum volume indexed to body surface area were measured by 3D echocardiography. LA functions (LA total stroke volume, LA active stroke volume, and LA active emptying fraction) were obtained from RT3D volumetric analysis. RESULTS: The results of the analysis revealed that type 2 diabetes mellitus showed enlarged V max, V min, and LAVi with an increased LA total stroke volume and decreased active emptying fraction, while type 1 diabetics showed only decreased in active emptying fraction. The LA maximum volume indexed to body surface area (LAVi) was significantly higher in type 2 diabetic patients as compared to normal controls which was 23.55 ± 3.37 ml/m2 versus 20.30. CONCLUSION: Patients with type 2 diabetes mellitus have an increased LA volume with impaired compliance and contractility, while patients with type 1 diabetes mellitus have only impaired contractility compared to nondiabetic subjects.

Vitamin B complex supplementation as a homocysteine-lowering therapy for early stage diabetic nephropathy in pediatric patients with type 1 diabetes: A randomized controlled trial.

BACKGROUND: Homocysteine levels are elevated in patients with type 1 diabetes mellitus (T1DM) and could induce renal injury. B vitamins have an important role in preventing microvascular complications of diabetes. AIM: We performed a randomized-controlled trial of oral supplementation with vitamin B complex as an adjuvant therapy for nephropathy in pediatric T1DM patients and assessed its relation to homocysteine and cystatin C as a marker of nephropathy. METHODS: This trial included 80 T1DM patients with microalbuminuria, despite oral angiotensin-converting enzyme inhibitors, aged 12-18 years with at least 5 years disease duration and HbA1c ≤8.5%. Patients were randomly assigned into two groups; intervention group which received oral vitamin B complex (B1, B6 and B12) once daily and placebo group. Both groups were followed-up for 12 weeks with assessment of plasma homocysteine, HbA1c, urinary albumin excretion (UAE) and cystatin C. RESULTS: Both groups were well-matched in baseline clinical and laboratory parameters. Baseline homocysteine levels were elevated in both groups compared with reference control values. After 12 weeks, supplementation with vitamin B complex for the intervention group resulted in a significant decrease of homocysteine, fasting blood glucose, HbA1c, triglycerides, total cholesterol, UAE and cystatin C compared with baseline levels (p < 0.001) and with placebo group (p < 0.001). No adverse reactions were reported. Baseline cystatin C was negatively correlated to vitamin B12 (r = -0.77, p = 0.001). CONCLUSIONS: Vitamin B complex improved glycemic control and renal function through decreasing homocysteine and could be a safe and effective strategy for treatment of early stage nephropathy in pediatric T1DM. This trial was registered at ClinicalTrials.gov (NCT03594240).

Role of speckle tracking echocardiography in detecting early left atrial dysfunction in hypertensive patients.

BACKGROUND: Arterial hypertension adversely affects left atrial (LA) size and function, effect on function may precede effect on size. Many techniques were used to assess LA function but with pitfalls. OBJECTIVES: Early detection of left atrial dysfunction with speckle tracking echocardiography in hypertensive patients with normal left atrial size. PATIENTS AND METHODS: The study was conducted on 50 hypertensive patients and 50 age matched normotensive controls, all with normal LA volume index and free from any other cardiovascular disease that may affect the LA size or function. They were all subjected to history taking, clinical examination and echocardiographic study with assessment of LA functions [total LA stroke volume, LA expansion index by conventional 2D echocardiography and Global peak atrial longitudinal strain by speckle tracking (PALS)], left ventricular (LV) systolic and diastolic functions, and LV mass. RESULTS: Different indices of LA dysfunction (Total LA stroke volume, LA expansion index and global PALS) were significantly lower in the hypertensive group despite the normal LA volume index in all the studied subjects. The presence of diabetes mellitus (DM) and higher grade of LV diastolic dysfunction were significantly associated with lower global PALS. The higher age, systolic blood pressure (BP), body mass index (BMI), LA volume index, and LV mass index and the lower LA expansion index were associated with lower global PALS. CONCLUSION: Speckle tracking echocardiography is a useful novel technique in detecting LA dysfunction in hypertension even before LA enlargement occurs.

Dorsal versus ventral strip augmented anastomotic bulbar urethroplasty: retrospective study.

PURPOSE: The published literature shows controversies with regard to the treatment of choice for longer stricture. Augmented anastomotic urethroplasty (AAU) was described for long bulbar urethral strictures with an extended area of narrowing and fibrosis, the technique combines the advantages of both anastomosis and graft substitution. We aimed to compare the dorsal and ventral strip anastomosis in the AAU. METHODS: A retrospective Review was conducted at the Department of Urology, Sohag University Hospital; we included adult patients with long bulbar urethral strictures (> 2 cm) who underwent dorsal or ventral strip AAU. Patients were followed at 1, 3, 6, and 12 months postoperatively for subjective improvements. The statistical analysis was carried with SPSS software version 24 for windows. RESULTS: At the end of follow-up, stricture recurrence occurred in 5 (12.5%) in ventral strip group compared to 6 (23.1%) in dorsal group, the difference was not statistically significant (p = 0.5). With regard to safety outcomes, there was no statistically significant difference between both groups in any of the postoperative complications, except post-void dribbling which showed higher incidence in dorsal strip group (p < 0.001). CONCLUSIONS: In conclusion, both dorsal strip and ventral strip techniques are feasible for long bulbar urethral strictures with comparable postoperative efficacy outcomes and high success rate.

Urethroplasty for treatment of long anterior urethral stricture: buccal mucosa graft versus penile skin graft-does the stricture length matter?

PURPOSE: To investigate the surgical outcomes of dorsal onlay urethroplasty (DOU) using buccal mucosa graft (BMG) or penile skin graft (PSG) and to assess the effect of stricture length in men with anterior urethral strictures. METHODS: A prospective cohort included men with anterior urethral strictures between 2008 and 2015. Patients underwent DOU using PSG or BMG. Patients had urethrography and uroflowmetry at 0, 3, 6, 12 months, and urethroscopy when needed. Student's t test, Mann-Whitney U tests, and Pearson's Chi-square test were used for analysis. RESULTS: Sixty-nine patients (43 ± 14 year) were included, 31 received BMG, and 38 received PSG. Mean stricture length was 8 ± 3 cm, mean operative time was 145 ± 31 min, and mean follow-up was 56 ± 10 mo. Success rate was 87 % (90 % BMG vs. 84 % PSG, p = 0.4). Mean operative time was significantly shorter in PSG group (136 ± 29 min vs. 256 ± 58 min, p = 0.0005). Complications of grade I developed in 36 % (wound infection = 10 %, postvoiding dribbling = 18.8 %). Thirty of 69 patients (43 %) had strictures ≥8 cm, and 39 (57 %) had strictures <8 cm-success rate was equal for both subgroups (87 %). Mean blood loss, mean operative time, and incidence of postvoid dribbling were significantly lower in strictures <8 cm. CONCLUSION: BMG and PSG have comparable success rates in treatment of long anterior urethral strictures. Operative time is significantly longer in BMG. Long-segment strictures are associated with longer operative time, more blood loss, and more occurrence of postvoid dribbling. However, the length of the stricture has no influence on the success rate and functional outcomes of DOU.

Non-variceal upper gastrointestinal bleeding in cirrhotic patients in Nile Delta.

BACKGROUND AND STUDY AIMS: Acute upper gastrointestinal bleeding (AUGIB) in cirrhotic patients occurs mainly from esophageal and gastric varices; however, quite a large number of cirrhotic patients bleed from other sources as well. The aim of the present work is to determine the prevalence of non-variceal UGIB as well as its different causes among the cirrhotic portal hypertensive patients in Nile Delta. METHODS: Emergency upper gastrointestinal (UGI) endoscopy for AUGIB was done in 650 patients. Out of these patients, 550 (84.6%) patients who were proved to have cirrhosis were the subject of the present study. RESULTS: From all cirrhotic portal hypertensive patients, 415 (75.5%) bled from variceal sources (esophageal and gastric) while 135 (24.5%) of them bled from non-variceal sources. Among variceal sources of bleeding, esophageal varices were much more common than gastric varices. Peptic ulcer was the most common non-variceal source of bleeding. CONCLUSIONS: Non-variceal bleeding in cirrhosis was not frequent, and sources included peptic ulcer, portal hypertensive gastropathy, and erosive disease of the stomach and duodenum.
