Buccal versus skin graft for two-stage repair of complex hypospadias: an Egyptian center experience.

BACKGROUND: Urethral reconstruction in complex hypospadias poses a significant challenge. We report our 10-year experience with buccal mucosa graft (BMG) in the two-stage repair of complex hypospadias and compare its results to the skin graft. METHODS: We retrieved the data of 15 patients with complex hypospadias who underwent two-stage repair using the BMG at our institution. The data were compared to 13 patients who underwent skin graft during the same period. RESULTS: The median follow-up duration was 14 (12-17) months in the BMG group and 16 (13.5-22.5) months in the skin graft group. Patients in the BMG had a numerically lower incidence of the diverticulum, wound dehiscence, fistula, and infection than the skin graft group, however, without statistically significant difference (p > 0.05). On the other hand, the incidence of meatal stenosis and urethral stricture was significantly lower in the BMG group (0% each) compared to the skin graft group (30.8% each; p = 0.02). At the same time, there were no reported cases of graft contracture. The frequency of donor site morbidity was significantly higher in the skin graft group compared to the BMG group (p = 0.003). The BMG led to a lower incidence of postoperative straining than the skin graft (0% vs. 38.5%, p = 0.03). Only one patient needed revision surgery after skin graft, compared to no case in the BMG (p = 0.27). CONCLUSION: The present study demonstrates the feasibility and durable outcomes of the BMG in the setting of two-stage repair of complex hypospadias.

Sensitive spectrophotometric determination of vardenafil HCl in pure and dosage forms.

OBJECTIVES: The present work aims to develop and validate a simple, rapid, cost-effective, sensitive and extractive spectrophotometric methods for the determination of phosphodiesterase type 5-inhibitor; vardenafil HCl (VARD) in pure and in dosage forms. METHODS: The developed methods are based on the formation of ion-pair complexes between vardenafil HCl and dyes, namely, bromocresol green (BCG), bromocresol purple (BCP), bromophenol blue (BPB), bromothymol blue (BTB) and eriochrom black T (EBT) in acidic buffer solutions. Different factors affecting the reactions between VARD and the dyes were studied and optimized. RESULTS: The formed complexes were extracted with methylene chloride and measured at 418, 410, 415, 417 and 520nm using BCG, BCP, BPB, BTB and EBT, respectively. The beer's law was obeyed in the ranges 1.0-10, 1.0-16, 0.5-8.0, 2.0-20 and 1.0-14µgmL-1 for BCG, BCP, BPB, BTB and EBT, respectively under the optimum conditions. The composition of the ion-pairs was found 1:1. The molar absorptivity's, Sandell's sensitivity, limits of detection and the limits of quantification were calculated. Other method validation parameters, such as accuracy, intra-day and inter-day precision, robustness, ruggedness and selectivity, have been evaluated. CONCLUSION: The proposed methods have been applied successfully for the analysis of vardenafil HCl in pure and dosage forms. The reliability of the methods was further ascertained by performing recovery studies using the standard addition method. Statistical comparison of the results with the reported method was performed by applying student's t- and F-tests and no significant statistical differences were obtained.

Pelvic floor muscle assessment on three- and four-dimensional transperineal ultrasound in women with ovarian endometriosis with or without retroperitoneal infiltration: a step towards complete functional assessment.

OBJECTIVES: Previous studies comparing women with deep infiltrating endometriosis (DIE) and healthy controls have underlined an association between pelvic floor muscle (PFM) hypertonic dysfunction and deep lesions. The aim of this study was to compare the morphometry of PFM in women affected by ovarian endometriosis with DIE vs those without DIE in order to assess the impact of retroperitoneal infiltration by the disease on PFM function. METHODS: This was a prospective study conducted between March 2015 and December 2016 on symptomatic women with a clinical and sonographic diagnosis of ovarian endometriosis with or without DIE, scheduled for laparoscopic surgery. We excluded patients with current or previous pregnancy, previous surgery for deep endometriosis, other causes of chronic pelvic pain or congenital or acquired abnormalities of pelvic floor anatomy. Three- and four-dimensional transperineal ultrasound was performed to evaluate PFM morphometry and assess levator hiatal area (LHA) and diameters at rest, during PFM contraction and during Valsalva maneuver. All volumes were analyzed offline by an investigator blinded to the clinical data. RESULTS: One hundred and fourteen patients with ovarian endometriosis were enrolled in the study, 75 with DIE and 39 without DIE. The diagnosis of endometriosis was confirmed by histological examination in all patients. Compared with women without DIE, women with DIE showed a smaller LHA at rest, during contraction and during Valsalva maneuver (P = 0.03, P = 0.03 and P = 0.02, respectively) and a smaller reduction in LHA during PFM contraction (P = 0.04). CONCLUSIONS: Women with ovarian endometriosis who were affected by DIE showed smaller hiatal dimensions than did women without DIE. Considering that PFM dysfunction in patients with DIE could cause pain symptoms and pelvic organ dysfunction, transperineal ultrasound could allow a more complete functional assessment and tailored therapy.

Combination of essential oil and ciprofloxacin to inhibit/eradicate biofilms in multidrug-resistant Klebsiella pneumoniae.

AIM: This study aimed to test biofilm inhibition activities of each of essential oils (EOs), main compounds of EOs and enzymes against pathogenic Klebsiella pneumoniae. METHODS AND RESULTS: The effect of seven EOs and three enzymes was tested on formation and eradication of K. pneumoniae biofilm. Peppermint oil showed a robust biofilm inhibitory effect, causing inhibition that ranged from 69·2 to 98·2% at 5 µl ml-1 . Thyme oil was found to have the best biofilm eradication ability, causing eradication that ranged from 80·1 to 98·0% at 10 µl ml-1 . The most effective EOs were analysed by GC/MS, to determine the major chemical constitutes of each oil. Pure menthol was found to cause 75·3-97·5% biofilm inhibition at 2·5 µg ml-1 , whereas thymol caused 85·1-97·8% biofilm eradication at 5 µg ml-1 . However, moderate inhibition activity was detected for α-amylase and bromelain, while poor activity was detected for ß-amylase. Ciprofloxacin combination with thyme oil and thymol was found to enhance antibiotic activity, and affect biofilm cell viability. The observed inhibitory/eradication activity on K. pneumoniae biofilms was confirmed by scanning electron microscopy. CONCLUSIONS: Thyme and peppermint EOs, and their active components are promising antibiofilm agents alone and/or in combination with ciprofloxacin to inhibit/eradicate biofilms of K. pneumoniae. SIGNIFICANCE AND IMPACT OF THE STUDY: The presented results suggest the potential application of EOs against infections, caused by biofilm-producing K. pneumoniae, to prevent biofilm formation or decrease their resistance threshold. Moreover, the combination of EOs with ciprofloxacin minimizes the antibiotic concentration used and accordingly the potential accompanying toxic side effects.

Pelvic floor muscle dysfunction on 3D/4D transperineal ultrasound in patients with deep infiltrating endometriosis: a pilot study.

OBJECTIVE: Pelvic floor muscle (PFM) dysfunction seems to play an important role in the pathophysiology of pelvic pain, including that associated with deep infiltrating endometriosis (DIE). The aim of this study was to evaluate the static and dynamic morphometry of the PFM using three-dimensional (3D) and four-dimensional (4D) transperineal ultrasound in women with DIE compared with asymptomatic healthy women. METHODS: This was a pilot, prospective study conducted at our tertiary center between March and November 2015. Fifty nulliparous women with DIE (study group) and 35 nulliparous asymptomatic healthy women (control group) were included. 3D/4D transperineal ultrasound examination of the PFM was performed in both groups. Levator hiatal area (LHA) and anteroposterior and left-right transverse diameters were evaluated at rest, on maximum PFM contraction and on maximum Valsalva maneuver. Persistent levator ani muscle (LAM) coactivation during Valsalva maneuver was investigated. RESULTS: Compared with the control group, women with DIE had a smaller LHA at rest (P = 0.03) and during Valsalva maneuver (P < 0.01). Furthermore, reduction in LHA during PFM contraction (P < 0.001) and enlargement in LHA during Valsalva maneuver (P = 0.01) were significantly less marked. In comparison with controls, women with DIE presented a higher frequency of LAM coactivation during Valsalva maneuver, although this difference did not reach statistical significance (P = 0.05). CONCLUSIONS: 3D and 4D transperineal ultrasound is an objective and non-invasive method for PFM morphometry and may have a role in detecting PFM dysfunction in women with DIE. Copyright © 2016 ISUOG.

Therapeutic outcome of 6198 interferon-naïve Egyptian patients with chronic hepatitis C: a real-life experience and lessons to be learned in DAAs' era.

Antiviral therapy for HCV infection has been validated in randomized controlled clinical trials, but its value in the real world is less well studied. There is relatively little data on real-world responses to interferon-based therapies for patients with genotype 4 infection. We aimed to examine experience with large-scale access to antiviral therapy in chronic HCV in a real-life clinical setting in Egypt. Detailed pretreatment data of 6198 IFN-naïve chronic HCV patients who had received PEG-IFN/RBV therapy at Cairo-Fatemic Hospital, Egypt, between 2009 and 2012 were obtained from the HCV database. At week 12, 95.7% of patients had undetectable HCV RNA, and by week 24 and 48, breakthrough was 6% and 4%, respectively. However, 43.7% of patients discontinued treatment prematurely, and intent to treat end of treatment response was 44.6% (79.3% per protocol). Sustai-ned response data were available from only 1281 patients and was 84.9%. Haematological abnormalities were comparable in patients who did or did not comply with therapy. This is the first real-world, large-scale experience of antiviral therapy in chronic HCV in Egypt. Suboptimal response in HCV predominantly genotype 4 was mainly driven by noncompliance as well as gaps in the healthcare system leading to treatment discontinuation. These results need to be considered in the era of all oral antiviral regimes.

Gene Polymorphism of Interleukin-4, Interleukin-4 Receptor and STAT6 in Children with Atopic Dermatitis in Taif, Saudi Arabia.

AIM OF STUDY: This work was performed to evaluate the level of IL-4, and to clarify the role of IL-4 gene polymorphism at position cytosine -590-to-thyamine (C-590T), IL-4Rα gene polymorphism at position adenine +4679-to-guanine (A+4679G) [isoleucine-50-valine (I50V)] and STAT6 gene polymorphism at position guanine 2964-to-adenine (G2964A) in Saudi children with non-atopic dermatitis (non-AD) and atopic dermatitis (AD) to identify their role in the pathogenesis of these diseases. SUBJECTS AND METHODS: This study included 150 children: 50 healthy children as controls, 50 with non-AD, and 50 with AD. They were subjected to full clinical examination, complete blood picture, skin prick test, and determination of serum interleukin-4 (IL-4) and total immunoglobulin-E (IgE) levels. Detection of interleukin-4 gene (C-590T), interleukin-4 receptor alpha gene (A+4679G) (I50V), and STAT6 gene (G2964A) polymorphisms were performed by PCR-based restriction fragment length polymorphism (PCR-RFLP). RESULTS: There was a significant (P < 0.01) association between genotype and allele frequencies of IL-4Rα (A+4679G) (I50V) polymorphism in the AD group (but not non-AD group). Moreover, there was a significant association between genotype and allele frequencies of the STAT6 (G2946A) polymorphism in the non-AD (P < 0.05) and AD (P < 0.01) groups. On the other hand, there was no significant association between genotype and allele frequencies of the (C-590T) polymorphism in the non-AD group and AD group. There was a significant (P < 0.001) higher total IgE level in patients compared to the controls. Moreover, the mean values of total IgE were significantly different among the different allelic variants of (C-590T), (I50V), (G2964A) polymorphisms of IL-4, IL-4Rα, and STAT6 genes, respectively, in all the studied groups. On the other hand, there was no significant difference of serum IL-4 levels among all the studied patients, or among the different allelic variants of (C-590T), (I50V), (G2964A) polymorphisms of IL-4, IL-4Rα, and STAT6 genes, respectively. CONCLUSION: IL-4Rα gene (I50V) and STAT6 gene (G2964) polymorphisms may play a role in development of eczema; however, the IL-4 gene polymorphism (C-590T) had no relationship with susceptibility to the disease among Saudi children.

Urodynamic evaluation and anorectal manometry pre- and post-operative bowel shaving surgical procedure for posterior deep infiltrating endometriosis: a pilot study.

STUDY OBJECTIVE: To analyze bowel and urinary function in patients with posterior deep infiltrating endometriosis (DIE) >30 mm in largest diameter at transvaginal ultrasound before and after surgical nerve-sparing excision. DESIGN: Prospective observational study (Canadian Task Force classification III). SETTING: Tertiary care university hospital in Bologna, Italy. PATIENTS: Twenty-five patients with posterior DIE were included in the study between June 2011 and December 2012. Patients did not receive hormone therapy for at least 3 months before and 6 months after surgery. INTERVENTIONS: Patients underwent urodynamic studies and anorectal manometry before and after nerve-sparing laparoscopic excision of the posterior DIE nodule. MEASUREMENTS AND MAIN RESULTS: Intestinal and urinary function was evaluated in patients with bulky posterior DIE using urodynamic and anorectal manometry. Results of urodynamic studies and anorectal manometry were similar before and after nerve-sparing surgical excision of the posterior DIE nodule. Urodynamic studies demonstrated a high prevalence of voiding dysfunction, whereas anorectal manometry showed no reduction in rectoanal inhibitory reflex and hypertone of the internal anal sphincter. CONCLUSIONS: Patients with posterior DIE >30 mm in greatest diameter demonstrate preoperative dysfunction at urodynamic study and anorectal manometry, probably due to DIE per se. The nerve-sparing surgical approach seems not to influence the motility or sensory capacity of the bladder and the rectosigmoid colon.

"The Green Peace" How ICG can prevent complications in endometriosis surgery?

This literature review summarises the investigation into using Indocyanine Green (ICG) in the surgical management of endometriosis, focusing mainly on its application in Deep Endometriosis (DE). The study reviews the development, fluorescence characteristics, and clinical usage of ICG in enhancing the precision of identifying endometrial lesions during surgery. Emphasizing the technology's contribution to improved lesion visualisation, the paper discusses how ICG facilitates increased diagnostic accuracy, potentially reducing recurrence rates and the necessity for subsequent interventions. Additionally, it explores ICG's role in minimizing the risk of iatrogenic injuries, especially in ureteral endometriosis, and its utility in surgical decision-making for rectosigmoid endometriosis by evaluating bowel perfusion. Conclusively, while acknowledging the clear benefits of ICG integration in endometriosis surgical procedures, the abstract calls for more extensive research to validate its efficacy and cost-efficiency in the broader context of endometriosis treatment.

Innovative Cadaveric Technique: Utilising n-Butyl Cyanoacrylate (n-BCA) for Deep Endometriosis Excision Simulation in Minimal Invasive Surgery Training.

Background: Our study aimed to create a novel technique using n-butyl cyanoacrylate (n-BCA) for minimal access simulation training on cadavers in deep endometriosis excision. Objectives: A step-by-step video demonstration of using n-BCA in cadavers to simulate deep endometriosis. This technique is integrated into training sessions using cadavers aimed at enhancing surgical proficiency for deep endometriosis procedures. Material and Methods: Video article describing using n-BCA in cadavers as a simulation model. Result: This technique has been used in a hands-on cadaveric training course, and positive feedback supports the recommendation to incorporate this technique. Conclusion: Utilizing a human cadaver model proves beneficial for enhancing understanding of deep pelvic innervation. Implementing n-BCA in these cadaver dissections demonstrates both reproducibility and safety. This approach significantly contributes to refining surgical expertise in the excision of deep infiltrating endometriosis.

The anatomy of the pelvic plexus in female cadavers: implications for retroperitoneal nerve-sparing surgery.

Background: The inferior hypogastric plexus (IHP) is a crucial structure for female continence and sexual function. A nerve-sparing approach should be pursued to reduce the risk of pelvic plexus damage during retroperitoneal pelvic surgery. Objectives: To analyse the relationship between the female IHP and several pelvic anatomical landmarks. Materials and Methods: Standardised cadaveric dissection was performed on 5 nulliparous female cadavers. The relationships of the IHP and the mid-cervical plane (MCP), the mid-sagittal plane (MSP), and the uterosacral ligament (USL) were investigated. Main outcome measures: Distance between IHP and MCP, MSP, and USL. Results: Distances between the right IHP and the right MSP (mean distance: 16.3 mm; range: 10.0-22.5 mm) and the right USL (mean distance: 4.8 mm; range: 0-15.0 mm) were shorter than those between the left IHP and ipsilateral landmarks (left MSP distance: 23.5 mm; range 18.0-30.0 mm; left USL distance: 5.0 mm; range: 0-20.0 mm). Although the MCP was 3.3 mm (range: 2.5-4.0 mm) left and lateral to the midsagittal line, the right IHP was closer to the MCP (mean distance: 19.6 mm; range: 13.0-25.0 mm) than the left one (mean distance: 20.2 mm; range: 15.0-26.0 mm). Conclusions: Distances between the right IHP and the MSP, MCP, and ipsilateral USL, are shorter compared to these associated to the left IHP. What is new?: Right autonomic pelvic plexus is closer to the midline planes and the ipsilateral USL. These anatomical relationships may be greatly helpful for pelvic surgeon while facing retroperitoneal pelvic surgery and looking for a nerve-sparing approach.

Segmental bowel resection for colorectal endometriosis: is there a correlation between histological pattern and clinical outcomes?

BACKGROUND: Laparoscopic segmental resection as a treatment for intestinal endometriosis can be supported by favorable clinical outcomes, but carries a high risk of major complications. The purpose of this study is to evaluate histopathological patterns of colorectal endometriosis and investigate potential relationships between histological findings and clinical data. METHODS: We consecutively included 47 patients treated with laparoscopic segmental resection because of symptomatic colorectal endometriosis. All patients underwent follow-up for a median of 18 months (range: 6-35). We examined the histological patterns of colorectal endometriosis and evaluated the relationships between histological findings (satellite lesions, positive margins and vertical infiltration) and clinical outcomes (incidence of recurrence, quality of life and symptom improvement). Moreover, we observed if satellite lesions could influence preoperative scores of the short form-36 health survey (SF-36) questionnaire and visual analogue score (VAS) for pain symptoms. RESULTS: There were no statistically significant differences in terms of anatomical and pain recurrences, pain symptoms and quality of life improvement among patients with or without positive margins, satellite lesions and different degrees of vertical infiltration (P > 0.05). Furthermore, women with or without satellite lesions were no different in terms of preoperative VAS of pain symptoms and SF-36 scores (P > 0.05). CONCLUSIONS: The presence of satellite lesions or positive resection margins does not seem to influence clinical outcomes of segmental colorectal resection. Similarly, satellite lesions do not appear to have a major role in determining preoperative clinical presentation. These results may be useful to reconsider the surgical strategy for bowel endometriosis.

Efficacy of neuromuscular electrical stimulation of calf muscles on nocturnal symptoms and quality of life in asthmatic children.

OBJECTIVE: To determine whether neuromuscular electrical stimulation of calf muscles could improve nocturnal symptoms and quality of life in asthmatic children. PATIENTS AND METHODS: Sixty children (8-12 years) with moderate asthma were randomly allocated to three groups (A, B, and C). The three groups completed 12 weeks of supervised breathing exercises for 30 min. In addition, group A completed neuromuscular electrical stimulation of the calf muscles and group B completed aerobic exercise in the same period. The intervention was conducted five days a week for 12 consecutive weeks. Pre-and post-treatment evaluations involved pulmonary function tests, the Children's Asthma Control Questionnaire, calf muscle isometric muscle force, six-minute walk test, and Pediatric Asthma Quality of Life Questionnaire. RESULTS: A significant increase in all measured variables was recorded in all groups in favor of group A (p < 0.001). However, calf muscle isometric muscle strength, and nocturnal symptoms were non-significant in group C (p > 0.05). There was a significant difference between groups A and C in all measured variables (p < 0.001) in favor of group A. Significant differences between groups B and C in all measured variables (p < 0.001) in favor of group B were also noted. No significant differences were seen between groups A and B (p > 0.05). CONCLUSIONS: Neuromuscular electrical stimulation of calf muscles is an excellent adjunct to breathing exercise programs in improving nocturnal symptoms and quality of life in asthmatic children. Moreover, it can serve as a considerable alternative to traditional physical training in periods of disease exacerbation.

Comparison of transvaginal sonography and double-contrast barium enema for diagnosing deep infiltrating endometriosis of the posterior compartment.

OBJECTIVES: To compare the diagnostic accuracy of transvaginal sonography (TVS) and double-contrast barium enema (DCBE) in the preoperative detection of deep infiltrating endometriosis (DIE) of the posterior compartment. METHODS: This was a prospective study of 69 consecutive patients with results of pelvic examination or symptoms suggestive of DIE of the posterior compartment. TVS and DCBE were performed before surgery by two groups of physicians specialized in endometriosis, each blinded to the results of the other technique. Imaging data were compared with histopathologic analysis of the resected specimen (gold standard). Sensitivity, specificity, positive and negative predictive values and test accuracies were calculated for both imaging modalities. RESULTS: Sixty seven of the 69 women had a nodule of DIE confirmed at laparoscopy and histopathologic examination. TVS diagnosed DIE in 57 (85%) of these patients, while DCBE revealed the presence of the lesion in 24 (36%) women. For the diagnosis of posterior DIE, TVS and DCBE had, respectively, a sensitivity of 85% and 36%, specificity of 100% and 100%, positive predictive value of 100% and 100%, negative predictive value of 17% and 4% and accuracy of 85.5% and 38%. In patients with pure bowel DIE the sensitivity was 91% and 43%, specificity was 100% and 100%, positive predictive value was 100% and 100%, negative predictive value was 29% and 6% and accuracy was 91% and 45%, respectively. CONCLUSIONS: TVS has a much higher sensitivity than does DCBE in detecting the presence of posterior DIE and should thus be regarded as the imaging modality of choice when there is clinical suspicion of the disease.

Hepatoprotective activity of quercetin against acrylonitrile-induced hepatotoxicity in rats.

Acrylonitrile is a potent hepatotoxic, mutagen, and carcinogen. A role for free radical-mediated lipid peroxidation in the toxicity of acrylonitrile has been suggested. The present study was designed to assess the hepatoprotective effect of quercetin against acrylonitrile-induced hepatotoxicity in rats. Liver damage was induced by oral administration of acrylonitrile (50 mg/kg/day/5 weeks). Acrylonitrile produced a significant elevation of malondialdehyde (138.9%) with a marked decrease in reduced glutathione (72.4%), and enzymatic antioxidants; superoxide dismutase (81%), and glutathione peroxidase (53.2%) in the liver. Serum aspartate aminotransferase, alanine aminotransferases, direct bilirubin, and total bilirubin showed a significant increase in acrylonitrile alone treated rats (115.5%, 110.8%, 1006.8%, and 1000.8%, respectively). Pretreatment with quercetin (70 mg/kg/day/6 weeks) and its coadministration with acrylonitrile prevented acrylonitrile-induced alterations in hepatic lipid peroxides and enzymatic antioxidants as well as serum aminotransferases and bilirubin. Histopathological findings supported the biochemical results. We suggest that querectin possess hepatoprotective effect against acrylonitrile-induced hepatotoxicity through its antioxidant activity.

[Laparoscopic surgery for endometrial cancer in overweight women]. / Utilizzo della laparoscopia nel trattamento chirurgico delle sovrappese affette da cancro dell' endometrio.

AIM: The aim of this study was to investigate the feasibility and safety of laparoscopic staging of overweight women with endometrial cancer and to compare the surgical outcomes among these patients with those managed by laparotomy. METHODS: This was a retrospective analysis (Canadian Task-force Classification II-3). We reviewed operative and hospital records of 70 patients with a body mass index >25 kg/m2 who underwent surgical treatment for endometrial cancer between 2001 and 2008. Thirty-five patients treated laparoscopically were compared to an equivalent group of patients treated by laparotomy. Operative and postoperative variables were afterwards assessed. RESULTS: Women in laparoscopic group had a significantly lower blood loss (median, 25th-75th percentiles: 1.2, 0.8-2.0 in laparoscopic versus 1.8, 1.0-2.8 in laparotomic group, P<0.05). No differences between both group in terms of operative time (median, 25th-75th percentiles: 165 min, 130-183 in laparoscopic versus 135 min, 110-170 in laparotomic; P>0.05) and mean number of pelvic and para-aortic lymph nodes removed (22 ± 8.4 versus 24 ± 6.2 and 9.2 ± 2.5 versus 9.3 ± 5 respectively; P>0.05). Length of urethral catheter and hospital stay were statistically higher in laparotomic group (two days versus three days; four days versus seven days respectively; P<0.05). CONCLUSION: Laparoscopic surgery in overweight women with endometrial cancer had equivalent surgical staging than women operated by laparotomy. With regard to postsurgical variables, overweight women who underwent laparoscopic surgery had better results than those treated by laparotomy.

Diagnosis and treatment of uncommon ileal endometriosis: a case report and literature review.

Endometriosis is defined as the presence of endometrial tissue outside the uterine cavity. It is a common finding in premenopausal women and commonly affects the gastrointestinal tract, especially the rectosigmoid tract. Small bowel involvement is rare and usually asymptomatic making diagnosis difficult. Here we report an uncommon case of exophytic ileal endometriosis surgically treated. Detailed pre-operative counselling on the risk of ileal surgery should always be considered in all cases with endometriosis requiring surgery. We also present a review of the literature regarding the clinical presentation, diagnosis, and treatment of this challenging condition.

Bone mineral density and vitamin D receptor polymorphism in beta-thalassemia major.

Osteoporosis is the most prevalent bone complication in beta-thalassemic patients despite regular transfusions and iron chelation therapy. Although its etiology is multi-factorial, genetic factors play an important role in pathogenesis. These factors have not yet been clearly defined, however, osteoporosis may be related to vitamin D receptor gene BsmI polymorphism. In this study, BsmI vitamin D receptor gene polymorphism was analyzed using polymerase chain reaction and BsmI restriction fragment length polymorphism in 42 regularly treated-beta-thalassemic patients of different ages. Bone mineral density was measured by peripheral quantitative ultrasound at the heel of the foot. Serum levels of alkaline phosphatase, calcium, phosphorus, ferritin and 25-hydroxyvitamin D3 were determined. Patients were divided into two groups according to pubertal signs: group I (22 children), and group II (20 adolescents and adults). The Z-scores of bone mineral density in both groups were -1.32 +/- -0.9 and -2.30 +/- -1.02 respectively, with a significant difference between the two groups. The height standard deviation and 25-hydroxyvitamin D3 were significantly decreased in group II compared to group I. Moreover, significantly lower bone mineral density and height standard deviation were detected among patients with BB vitamin D receptor genotype. Therefore, this genotype may be considered as a risk factor for osteoporosis in beta-thalassemic patients.
