ABSTRACT
Abstract Introduction Phagocytosis of autoantibody-sensitized coated platelets through Fc gamma receptors on phagocytic cells is an important mechanism of thrombocytopenia in primary immune thrombocytopenia (ITP). Objective We aimed to investigate the contribution of the FcγRIIa and FcγRIIIa genes polymorphism to the risk of ITP and their association with disease characteristics in Egyptian children. Methods A case control study was conducted on eighty children with primary ITP and eighty age and sex healthy matched subjects as a control group. The FcγRIIa and FcγRIIIa genes polymorphism was detected using the polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). Results We found that the FcγRIIa‐131H and ‐131R allele frequencies were 51.3 % and 48.7%, respectively, in children with ITP, versus 75% and 25%, respectively, in controls (p= 0.002). The compound heterozygous HR genotype was significantly higher in ITP patients (p < 0.05). The FcγRIIIa-158F and ‐158V allele frequencies were 46.3% and 53.7%, respectively, in children with ITP, versus 70% and 30%, respectively, in controls (p= 0.002). The compound heterozygous VF genotype was significantly higher in ITP patients (p < 0.05). The combined HR/FV genotype was 47.5% in ITP patients, versus 10% in controls (p < 0.001). No significant difference was found between children with newly diagnosed ITP and those who developed chronic ITP, regarding the frequency distribution of the FcγRIIa and FcγRIIIa alleles and genotypes (p > 0.05). Conclusion There is a possible association of the FcγRIIa and FcγRIIIa genes polymorphism with the risk for, and genetic susceptibility to ITP in Egyptian children, but large-scale studies are still needed to support our findings.

Objective@#To determine the efficacy of concentric vs. eccentric exercise in improving shoulder function, pain, and tendon characteristics for patients with rheumatoid arthritis and rotator cuff tendinopathy. @*Methods@#Forty patients with rheumatoid arthritis and rotator cuff tendinopathy were divided into either concentric or eccentric exercise groups, with 20 patients in each group. Patients received 12 sessions at a pace of 3 sessions per week. Shoulder Pain and Disability Index (SPADI), the visual analogue scale (VAS), supraspinatus and subscapularis thickness, echo pixels, and the Disease Activity Score-28-erythrocyte sedimentation rate (DAS-28-ESR) were assessed at baseline and post-treatment. @*Results@#There was a significant difference between the concentric and eccentric groups regarding SPADI and VAS scores in favor of the eccentric group. However, there was no significant difference between the two groups regarding tendon thickness, echo pixels, or DAS-28-ESR. @*Conclusion@#Eccentric exercises were more effective than concentric exercises in improving shoulder function and pain intensity. However, neither of the two types of exercises was superior in improving tendon characteristics or disease activity.
ABSTRACT
Resumo Este estudo teve como objetivo avaliar a resistência à fractura do silicato de lítio reforçado com zircônio todo o material cerâmico "Celtra Press" em comparação com um "IPS e-max Press" em condições orais simuladas. Quatorze coroas cerâmicas foram fabricadas em moldes epóxi que foram duplicados a partir de moldes principais de aço inoxidável e divididos em dois grupos iguais (n=7) de acordo com o material de construção; Grupo A: Coroas fabricadas com material IPS e-max Press e Grupo B: Coroas fabricadas com material Celtra Press. As coroas foram então cimentadas nos seus moldes correspondentes com um cimento de resina auto-adesivo e submetidas a ciclos térmicos e cargas cíclicas. Em seguida, foram carregadas para fraturar numa máquina universal de ensaios. Os resultados foram tabulados e analisados estatisticamente utilizando os testes Kolmogorov-Smirnov e Shapiro-Wilk. O teste t de Student usado para comparar os valores médios. O nível de significância foi fixado em P ≤ 0,05 e intervalo de confiança de 95%. A análise estatística foi realizada utilizando o software Graph Pad Instat (Graph Pad, Inc.) para Windows. Os valores médios ± SD da resistência à fractura foram registados para o grupo Disilicate de lítio (1706,01 ±154,32 N) enquanto que os valores médios ± SD registados com o grupo celtra foram (1550,67±196,71 N). As coroas cerâmicas de silicato de lítio reforçado com zircónio produziram valores de resistência à fractura comparáveis aos das coroas cerâmicas de dissilicato de lítio e ambos os materiais testados estão dentro dos valores clinicamente aceitáveis na área posterior.
Abstract The aim of this study was conducted to assess the fracture resistance of zirconia reinforced lithium silicate all ceramic material "Celtra Press" compared to lithium disilicate one "IPS e-max Press" under simulated oral conditions. Fourteen ceramic crowns were fabricated on epoxy dies which were duplicated from stainless steel master die and divided into two equal groups (n=7) according to the material of construction; Group A: Crowns fabricated with IPS e-max Press material and Group B: Crowns fabricated with Celtra Press material. The crowns were then cemented onto their corresponding dies with a self-adhesive resin cement and subjected to thermocycling and cyclic loading. Then they were loaded to fractur in a universal testing machine. The results were tabulated and statistically analyzed using Kolmogorov-Smirnov and Shapiro-Wilk tests. Student t-test used to compare mean values. The significance level was set at P ≤ 0.05 and 95% Confidence interval. Statistical analysis was performed using Graph Pad Instat (Graph Pad, Inc.) software for windows. The mean ± SD values of fracture resistance were recorded for lithium Disilicate group (1706.01 ±154.32 N) meanwhile the mean ± SD value recorded with celtra group were (1550.67±196.71 N). Zirconia reinforced lithium silicate ceramic crowns produced comparable fracture resistance values to lithium disilicate ceramic crowns and both tested materials are within the clinically acceptable values in the posterior area.
ABSTRACT
SUMMARY: Osteoporosis is a bone condition marked by a loss of bone mass and a disruption of bone microarchitecture. Men lose bone density as they age, resulting in brittle bones. The loss of free testosterone is one of the key factors. The objective of present study was to evaluate Allolobophora caliginosa extract (AcE) for its anti-osteoporotic and antiapoptotic activity in orchiotomized rat model at two different dose levels. Twenty eight male rats were divided into two groups. The first group represented sham operated rats while the second group underwent bilateral orchidectomy (OCX). After one week of recovery from orchidectomy surgery, the second group was randomly subdivided into 3 subgroups. The first OCX subgroup was administered orally distilled water daily for 10 weeks. The other two OCX subgroups were administered AcE (100 or200 mg/kg body weight/day) orally for 10 weeks. Orchiectomy induces remarkable loss of the cortical as well as trabecular bone loss; which, could be counterbalanced by Allolobophora caliginosa extract (AcE) that prevented cortical as well as trabecular bone loss. Allolobophora caliginosa extract (AcE) at Dose 200 mg/kg/day was found to be effective at a highly significant level in osteoporotic bone, as determined by histological images and immunohistochemical study, where Dose (100 mg/kg/day) was found to be moderately significant.In the present study, it is suggested that AcE may inhibit steroid-induced osteoblasts apoptosis, potentially via upregulation of Bcl-2 and downregulation of caspase-3. Allolobophora caliginosa extract demonstrates anti-apoptotic and anti-oxidant properties. Therefore, AcE may be used for the prevention of steroid-induced bone damage.
RESUMEN: La osteoporosis es una afección ósea caracterizada por una pérdida de masa ósea y una alteración de la microarquitectura ósea. Los hombres pierden densidad ósea a medida que envejecen, lo que resulta en huesos quebradizos. La pérdida de testosterona libre es factor clave en este proceso. El objetivo del presente estudio fue evaluar el extracto de Allolobophora caliginosa (AcE) debido a su actividad antiosteoporótica y antiapoptótica en un modelo de rata orquiectomizadas con dos niveles de dosis diferentes. Se dividieron veintiocho ratas macho en dos grupos. El primer grupo incluyó ratas con operación simulada, mientras que el segundo grupo se sometió a orquidectomía bilateral (OCX). Después de una semana de recuperación de la orquidectomía, el segundo grupo fue subdividido en 3 subgrupos. Al primer subgrupo de OCX se administró diariamente agua destilada por vía oral durante 10 semanas. Los otros dos subgrupos de OCX se administraron por vía oral AcE (100 o 200 mg / kg de peso corporal / día) durante 10 semanas. La orquidectomía induce una pérdida notable del hueso cortical y trabecular; el cual podría ser contrarrestado por el extracto de Allolobophora caliginosa (AcE) que previno la pérdida de hueso tanto cortical como trabecular visualizado en imágenes histológicas y estudio inmuno- histoquímico, donde se encontró que la dosis (100 mg / kg / día) era moderadamente significativa. En el presente estudio, se sugiere que la AcE puede inhibir la apoptosis de los osteoblastos inducida por esteroides, potencialmente a través de la regulación al alza de Bcl 2 y la regulación a la baja de caspasa 3. El extracto de Allolobophora caliginosa demuestra propiedades anti apoptóticas y antioxidantes. Por lo tanto, AcE puede usarse para la prevención del daño óseo inducido por esteroides.

Background@#The thoracic retrolaminar block (TRLB) is a relatively new regional analgesia technique that can be used as an alternative to the thoracic paravertebral block. This study aimed to evaluate the postoperative analgesia effects of ultrasound-guided TRLB in children undergoing open cardiac surgery via median sternotomy incision. @*Methods@#Sixty-six patients aged 2–8 years were recruited. In the TRLB group, 0.25% bupivacaine 0.4 ml/kg was injected into the retrolaminar space on both sides at the level of the T4 lamina. Patients in the control group were injected with 0.9% saline. The primary outcome measure was fentanyl consumption in the first 24 h post-extubation. The secondary outcome measures were the total intraoperative fentanyl consumption, postoperative modified objective pain score (MOPS), and time to extubation. @*Results@#The total intraoperative fentanyl requirements and fentanyl consumption in the first 24 h post-extubation were significantly lower (P < 0.001) in the TRLB group (9.3 ± 1.2; 6.9 ± 2.1 μg/kg, respectively) than in the control group (12.5 ± 1.4; 16.6 ± 2.8, respectively). The median (Q1, Q3) time to extubation was significantly shorter (P < 0.001) in the TRLB group (2 [1, 3] h) than in the control group (6 [4.5, 6] h). The MOPS was significantly lower (P < 0.05) in the TRLB group than in the control group at 0, 2, 4, 8, 12 and 16 h post-extubation. @*Conclusions@#Bilateral ultrasound-guided TRLB is effective in providing postoperative analgesia in children undergoing open cardiac surgery via median sternotomy incision.
ABSTRACT
Objective:To investigate the short term clinical efficacy of intra-gastric balloon (IGB) on obesity patients with different body mass index (BMI).Methods:The retrospective and descriptive study was conducted. The clinical data of 62 obesity patients with different BMI who were admitted to three medical centers, including 56 cases in the Hurstville Private Hospital, 4 cases in the St George Private Hospital of University of New South Wales and 2 cases in the East Sydney Private Hospital, from January 2017 to December 2021 were collected. There were 15 males and 47 females, aged 45.1(range, 18.0 to 67.0)years, with the BMI of 35.1(range, 27.8 to 48.4)kg/m 2. Of the 62 patients, there were 33 cases with 27 kg/m 2≤BMI<35 kg/m 2 and 29 cases with BMI≥35 kg/m 2. Observation indicators: (1) first operation and postoperative complications; (2) follow-up after first IGB; (3) recurrent IGB and postoperative complications; (4) follow up after recurrent IGB. Follow-up was conducted using outpatient examinations to detect postoperative complications and weight loss effects. Patients were followed up at postoperative 1, 3, 6 month. Measurement data with normal distribution were represented as Mean± SD, and measurement data with skewed distribution were represented as M (range). Count data were described as absolute numbers. Results:(1) First opera-tion and postoperative complications. All 62 obesity patients underwent the first IGB successfully. Of the 62 patients, 45 cases had postoperative complications, including 38 cases with gastroesophageal reflux, 12 cases with dysphagia or burping, 9 cases with epigastric pain and 4 cases with nausea. One patient may have multiple complications. Cases with above complications in the 33 cases with 27 kg/m 2≤BMI<35 kg/m 2 and 29 cases with BMI≥35 kg/m 2 were 21, 8, 7, 2 and 17, 4, 2, 2, respectively. (2) Follow-up after first IGB. Of the 62 obesity patients, there were 52, 46 and 38 cases completing followed up at postoperative 1, 3 and 6 month, respectively, including 30, 25,20 cases in patients with 27 kg/m 2≤BMI<35 kg/m 2 and 22, 21, 18 cases in patients with BMI≥35 kg/m 2. Of the 62 obesity patients, there were 15 cases requiring early balloon extraction due to intractable symptoms, inclu-ding 7 cases with ongoing dysphagia or burping, 6 cases with complaining of ineffective weight loss, 1 case with acute right-sided abdominal pain and 1 case with a serendipitous discovery of pregnant. The cumulative weight loss of the 30 cases with 27 kg/m 2≤BMI<35 kg/m 2 and 22 cases with BMI≥35 kg/m 2 at postoperative 1 month was (4.8±3.0)kg and (6.6±2.8)kg, respectively. The above indicator was (6.7±4.4)kg and (10.6±4.8)kg at postoperative 3 month for the 25 cases with 27 kg/m 2≤BMI<35 kg/m 2 and 21 cases with BMI≥35 kg/m 2, and (8.5±4.8)kg and (9.8±3.9)kg at postoperative 6 month for the 20 cases with 27 kg/m 2≤BMI<35 kg/m 2 and 18 cases with BMI≥35 kg/m 2. The percentage of excess weight loss was 53%±26% and 29%±15% at postoperative 6 month and the percentage of total weight loss was 14%±5% and 10%±5% at postoperative 6 month for the 20 cases with 27 kg/m 2≤BMI<35 kg/m 2 and 18 cases with BMI≥35 kg/m 2, respectively. (3) Recurrent IGB and postoperative complications. Of the 38 cases completing the postoperative 6 month followed up after the first IGB, 9 cases with 27 kg/m 2≤BMI<35 kg/m 2 and 7 cases with BMI≥35 kg/m 2 choosing a second IGB immediately after the removal of the first balloon. Cases with postoperative compli-cations, including gastroesophageal reflux, dysphagia or burping, epigastric pain, nausea were 4, 3, 0, 0 in patients with 27 kg/m 2≤BMI<35 kg/m 2 and 4, 0, 2, 1 in patients with BMI≥35 kg/m 2. (4) Follow up after recurrent IGB. All the 16 patients who chosen a second IGB completed the postoperative 6 month followed up, with the cumulative weight loss of (8.8±8.5)kg and (18.9±9.7)kg and the percentage of excess weight loss of 44%±38% and 41%±15% in the 9 cases with 27 kg/m 2≤BMI<35 kg/m 2 and 7 cases with BMI≥35 kg/m 2, respectively. Conclusions:IGB can achieve a good short-term weight loss effects in obesity patients with BMI≥27 kg/m 2.

ABSTRACT
Objective: Head and neck cancer is the sixth leading cancer by incidence worldwide and eighth by death. Recent reports revealed that, not only radiotherapy but also chemotherapy may induce xerostomia. The aim of this study was to compare the possible regenerative effect of BMSCs through systemic and local injections. Material and Methods: 52 male Albino rats were randomly divided into 4 groups: Group 1: 10 rats received 0.5 ml of PBS by injection. Group 2: 14 rats received an intraperitoneal injection of 5-FU drug. Group 3: 14 rats were injected the same dose of 5-FU then received an intraglandular transplantation of BMSCs suspended in 0.5 ml of PBS at day 1 after 5-FU administration. Group 4: 14 rats were injected the same dose of 5-FU then received an intravenous injection of BMSCs suspended in 0.5 ml of PBS via the tail vein at day 1 after 5-FU administration. Results: Histological examination showed that group 2 showed features of severe degenerative changes which increased over time. Group 3 showed increasing amelioration in the ductal structure overtime. Group 4 also showed regenerated ductal elements however concerning apoptotic changes, immunohistochemistry results revealed improvement in both group 3 and 4 over group 2 with no statistical difference between groups 3 and 4. Conclusion: Histological and immunohistochemical features in group 3 and group 4 revealed similar amelioration in regenerative potentials. On the other hand, regenerative features of both experimental groups were statistically significant as compared independently to group 1 (AU)

Abstract Trichinellosis is a zoonosis results from eating raw or semi-cooked meat of infected animals. Medicinal plants have been used lately as alternatives and/or combined therapies to resolve some drawbacks of the current regimens. This work analyzed the effect of albendazole monotherapy on Trichinella spiralis experimental infection (group A), in comparison to P. granatum and amygdalin extracts +cobalamin (group B), plus its combination with albendazole (group C). The study revealed that the extracts alone or combined with albendazole had an inferior effect to albendazole monotherapy regarding number of adult worms (40.83 ±3.82, 18.67 ±1.86 and 16.83 ±2.32, respectively). However, their effect was more obvious in muscle phase combined with albendazole, achieving the lower number of larvae/mL tissue homogenate (22.33 ±3.27 in comparison to 39.67 ±2.58 achieved by albendazole monotherapy). The extracts exerted a significant immunomodulatory effect by reducing the local CD4+ expression in the intestine as well as in muscle phase (1.15 ±0.25 and 3.80 ±0.65 in comparison to 4.97 ±0.37 and 12.20 ±0.87 with albendazole monotherapy, respectively). So, these extracts improved the therapeutic efficacy of albendazole, specifically in muscle phase and counteracted the inflammatory reaction caused by albendazole monotherapy, thus extensively alleviating the resulting myositis.
Resumo Trichinellosis é uma zoonose resultante da ingestão de carne crua ou semicozida de animais infectados. As plantas medicinais têm sido usadas, ultimamente, como alternativas e/ou terapias combinadas, para resolver algumas desvantagens dos regimes atuais. Este trabalho analisou o efeito da monoterapia albendazole na infecção experimental por Trichinella spiralis (grupo A), em comparação com extratos de P. granatum e amígdalina +cobalamina (grupo B), além de sua combinação com albendazol (grupo C). O estudo revelou que os extratos sozinho ou combinado com albendazol teve efeito inferior à monoterapia albendazol em relação ao número de vermes adultos (40,83 ±3,82, 18,67 ±1,86 e 16,83 ±2,32, respectivamente). No entanto, seu efeito foi mais óbvio na fase muscular combinado com o albendazol, alcançando o menor número de larvas/mL homogeneizado de tecido (22,33 ±3,27 em comparação com 39,67 ±2,58 obtidos pela monoterapia albendazol). Os extratos exerceram um efeito imunomodulatório significativo, ao reduzir a expressão local CD4+ no intestino, bem como na fase muscular (1,15 ±0,25 e 3,80 ±0,65 em comparação com 4,97 ±0,37 e 12,20 ±0,87 com monoterapia albendazol, respectivamente). Assim, esses extratos melhoraram a eficácia terapêutica do albendazol, especificamente na fase muscular e neutralizaram a reação inflamatória causada pela monoterapia albendazol, aliviando extensivamente a miosite resultante.

ABSTRACT
Objective: The study aims to evaluate the emotional, behavioural, and social effects of single or multiple anterior tooth loss. It also compares the effectiveness of the removable and fixed prosthesis to address the impact of anterior tooth loss. Material and Methods: The study was carried out on 70 subjects who presented to the Department of Prosthetic Dental Sciences. A questionnaire was distributed and the data were statistically analyzed using SPSS version 18.0 and values less than 0.05 % were considered statistically significant. Results: The participant's difficulty to accept loss of their anterior tooth, embarrassment and confidence were changed significantly after wearing the prosthesis (P< 0.05). Moreover, fixed partial denture had more effect than removal partial denture. It was claimed by 62.9% of the participants that they were not prepared for the effect of tooth loss and 47.1% of them thought that a prior explanation from the dentist would have helped them overcome their fear of losing their teeth. Conclusion: The maximum impact of anterior tooth loss was felt on confidence followed by embarrassment. The participants felt more comfortable after wearing their prosthesis. Fixed partial denture had more effect than removable partial denture.(AU)

The second group (group B), include patients who undergopharmaco-invasive strategy, PCI within 24 hour afterthrombolysis (76 patients). the second group, coronary angiography was done immediately in cases of failedthrombolysis and for successful thrombolysis; coronaryangiography was performed within 3 –24 hours. Results:During hospital stay, more patients in group A3 died than those of group B orgroup A1, A2 with no statistical significance.In addition, morepatients in group A3 showed heart failure symptoms withstatistical significance than those of group B, A1 and A2. Bleeding complications occurred significantly moreingroupB. Duringfollowupvisits more patients in group A3 complained ofheart failure symptoms with statistical significance than those of group B, A1, A2 patients. Conclusion:Primary PCIwithout door to balloon time delay (≤90 minutes)was encouraged and hadthebest results on morbidity and mortality. Also, pharmacoinvasive strategy was encouraged as being better than primary PCIwhen door to balloon time showed marked delay( <90 minutes)
ABSTRACT
Gastric volvulus is a surgical emergency that requires prompt recognition and management. The acromegalic patient has a number of pathophysiological factors that predispose to gastric volvulus and slow gastrointestinal (GI) transit. Authors aimed to present a case of hiatus hernia and gastric volvulus in a patient with acromegaly and review the current literature on GI anomalies in this population. A 70-year-old female presented to our institute with epigastric pain and coffee-ground vomiting on the background of acromegaly secondary to pituitary adenoma (resected in 1997). She was found to have a gastric volvulus and hiatus hernia which was repaired laparoscopically. She was discharged home but re-presented six days later with abdominal distension and vomiting. Computed tomography (CT) scan of abdomen showed recurrent gastric volvulus with involvement of the transverse colon. She underwent a laparotomy but no evidence of gastric or colonic volvulus was seen intra-operatively. The CT findings were attributed to a large stomach and coiled redundant transverse colon which could be misinterpreted as volvulus on imaging. Gastroparesis and slow bowel transit were the likely aetiology of this second presentation. This is consistent with literature reporting slow bowel transit and dolichocolon in acromegalic patients. Gastric volvulus is a rare finding associated with acromegaly. Structural anomalies in the anatomy of the acromegalic patient can make CT diagnosis challenging. This case demonstrates the need for caution when interpreting imaging in this cohort, as well as the need for further research on GI pathology associated with acromegaly.
ABSTRACT
Background: Coagulopathy is commonly observed in poly-traumatized patients and is a known contributor to trauma mortality. Although, the incidence of coagulopathy is strongly associated with the severity of the injury, coagulopathy itself exerts an independent factor on mortality.Methods: This is a prospective, observational study on 100 trauma patients. All patients were evaluated using the modified shock index (MSI). Coagulation profile tests including platelet count, prothrombin time (PT), partial thromboplastin time (PTT), D-dimer and fibrinogen/fibrin degradation products (FDPs) were performed for all patients on admission and at 12 hours intervals. Statistically, a logistic regression analysis was performed of coagulation profile tests to determine the incidence of trauma induced coagulopathy (TIC) and its impact on 24 hours mortality. Correlation between clinical and laboratory status was done.Results: There was a statistically significant difference between the dead and the survived patients in the coagulation profile tests and MSI. The best cut-off point of each parameter of coagulation profile tests (PLT count, PT, PTT, d-dimer, FDPs) and MSI was calculated using receiver operating characteristic curve and were <173 × 109/l, >18.7 s, >31 s, >5 mg/l, > 321.5 mg/l and 1.6 respectively. Trauma induced coagulopathy in our study was defined by more than 2 of the following: PLT <173 × 109/l, PT >18.7 s, activated partial thromboplastin time (APTT) >31 s, D-dimer >5 mg/l and FDPs>321.5 mg/l with a p value 0.001 and associated with increased mortality.Conclusions: The incidence of trauma induced coagulopathy early after trauma is high and its severity is related to the injury itself. It is independent predictor of mortality. TIC was developed with presence of more than 2 of the coagulopathy parameters.
ABSTRACT
Two isolations of fungi from a bank of microorganisms in the Biological Sciences Laboratory at Escuela Superior Politécnica de Chimborazo were tested on the galling caused by Meloidogyne incognita in tomato seedlings grown in pots with substrate infested with a suspension of nematodes, with approximately 2000 juvenile stages (J2) from root galls of plants infested with M. incognita, taken from the Nematology laboratory of the Ecuadorian Agricultural Quality Assurance Agency (AGROCALIDAD). Pleurotus ostreatus was a fungus with nematicidal characteristics through production of toxins; while Trichoderma harzianum is a widely known fungus, although it is a plant growth promoter rather than a nematicide. The two fungi were formulated in wheat straw and rabbit manure. A complete randomized design (CRD) with three replications was used, with a chemical control (Fenamiphos) and an absolute control. Five grams of each formulation was applied per plant before the transplant. The number of galls in the roots, plant height, stem diameter, number of leaves and fresh and dry weight of the aerial part and roots of 180 tomato plants grown in greenhouse were evaluated at 60 days after transplant. The results showed that the two fungi reduced the number of galls and made it possible to obtain dry weights of the aerial and radicular part very close to the chemical control (10.09 and 3.39 g) with 8.68; 8.04; 2.96 and 3.25 g respectively. Besides Trichoderma harzianum proved to be a good promoter of root growth, therefore, the use of these bioformulates is a promising measure for the control of this phytonematode

Background@#Adipofascial flaps covered with a skin graft address the challenges involved in reconstructing dorsal foot defects. The purpose of this study was to describe a large adipofascial flap based on the perforators of the dorsalis pedis artery for large foot defects. @*Methods@#Twelve patients aged 5–18 years with large soft tissue defects of the dorsal foot due to trauma were treated with an extended dorsalis pedis adipofascial flap from May 2016 to December 2018. The flap was elevated from the non-injured half of the dorsum of the foot. Its length was increased by fascial extension from the medial or lateral foot fascia to the plantar fascia to cover the defect. All perforators of the dorsalis pedis artery were preserved to increase flap viability. The dorsalis pedis artery and its branches were kept intact. @*Results@#The right foot was affected in 10 patients, and the left foot in two patients. All flaps survived, providing an adequate contour and durable coverage with a thin flap. Follow-up lasted up to 2 years, and patients were satisfied with the results. They were able to wear shoes. Donor-site morbidity was negligible. Two cases each of partial skin graft loss and superficial necrosis at the tip of the donor cutaneous flap occurred and were healed by a dressing. @*Conclusions@#The hinged multiperforator-based extended dorsalis pedis adipofascial flap described herein is a suitable method for reconstructing dorsal foot defects, as it provides optimal functional and aesthetic outcomes with minimal donor site morbidity.

@#AIM: To study the changes in choroidal thickness in central serous chorioretinopathy(CSCR)over a 3mo follow-up using spectral domain optical coherence tomography(SD-OCT).<p>METHODS: This prospective study included 60 eyes, both eyes of 20 patients(mean age: 33.65±5.24 years)with classic acute unilateral central serous chorioretinopathy and normal fellow eye and 20 eyes as healthy controls. Fluorescein angiography and OCT were done. The subfoveal choroidal thickness(SFCT), central macular thickness(CMT), 1000 μm temporal and nasal to the centre of the fovea and the subretinal fluid were measured.<p>RESULTS: There was a statistically significant difference in SFCT among the three groups at the three different locations. SFCT in eyes with CSCR(372.40±34.39 μm)was significantly greater than that in each of the unaffected fellow eyes(302.10±8.9 μm)and control eyes(279.80±14.49 μm)at the base line and after 3mo follow-up. The mean CMT in CSCR was 317±141.86 μm, with a statistically significant positive correlation between SFCT and CMT.<p>CONCLUSION: The increase in the choroidal thickness at different locations as well as hyper-dilated and hyper-permeable vessels known as “pachychoroid” seems to play an important role in a broad spectrum of diseases that includes central serous chorioretinopathy.
