Introduction and Aim: Osteogenesis imperfecta (OI) cause health problems in all tissues contain type-1 collagen. The patient is complaining from easily fragile bones due to loss endochondrial normal ossification. Different treatment techniques are in use. Telescopic nails gain wide acceptance to treat OI since its introduction. However, it newly introduced in our institution. The aim of this work was to assess the results of surgical intervention of osteogenesis imperfecta with corkscrew tipped telescopic nail
Patients and methods: This prospective case series included 10 cases of OI, and treated surgically with corkscrew tipped telescopic nail and followed up for six months. The study completed during the period from January to August 2020. It was ethically accepted and an informed consent signed by the patient or his/her guardians. Each included patient was subjected to full history, physical examination and laboratory examinations. In addition, an X-ray had been performed. The orthopedic repair was performed and every patient had a cast after surgery. The collected data included operative time, duration of hospital stay. Postoperatively, patient ambulation was encouraged.
Results: Patients were 7 males (70.0%) and 3 females (30.0%). Their age ranged between 3 and 10 years. The operation was for tibia in 40% and femur in 100%. The postoperative complications were infection in 10%, and migration of the nail in 10%. No union or fracture after nailing was reported.
Conclusion: Telescopic nailing is an effective and relatively safe technique in the management of osteogenesis imperfecta.

Published: April 2023

Background: Peritrochanteric fractures are frequent of the proximal femur and represents about half of all proximal femur fractures. They are associated with disability, mainly in elder patients. Its management aiming to achieve immediate ambulation and to regain the pre-operative ambulation.
Aim and objectives; to evaluate and assess the functional and radiological outcomes of primary prosthetic replacement in old age cases of unstable per-trochanteric femur fractures,
Subjects and methods: The current work was an interrupted time series clinical trial (quasi experimental), included 15 patients suffering from unstable per-trochanteric fracture presented to us within a week of sustaining injury. They were clinically assessed and checked for fitness for surgery. Then and after surgery, they were followed by for functional outcome by Harris Hip Scale and any complications were recorded.
Results: Patients age ranged between 61 and 94 years. Females were more affected than males (80.0% vs 20.0%). Associated comorbidities were hypertension, diabetes and both conditions among 33.3%, 6.7% and 33.3%, successively. Falling was the commonest mode of injury (60.0%), and the left side was more affected than the right (60.0% vs 40.0%). Associated injuries were 1(6.7%) fracture surgical neck hummers, 1(6.7%) contralateral both bone leg fracture, 1(6.7%) had fracture mid shaft ulna. Regarding outcome, all cases were free from postoperative complications. However, blood loss was reported among 11(73.3%). Twelve (80%) patients had an excellent, 2 (13.3%) had good and 1(6.7%) had fair functional outcome. There was significant association between functional outcome and patients, gender, associated comorbid medical conditions, mode of trauma, side of trauma, or blood loss.
Conclusion: Primary prosthetic replacement is a valid surgical option in management of unstable trochanteric fractures in elderly. The main advantages are the safety, effectiveness and early full weight bearing.

Published: April 2023

Introduction and Aim: Ankle fractures are common fractures encountered by the orthopedic surgeons in their daily clinical practice. The syndesmosis complex stabilizes the mortis by securing the fibula into the fibular notch. The current work aimed to evaluate the outcome of suture button fixation for treatment of distal tibiofibular syndesmotic injuries.
Patients and methods: This was a quasi-experimental study. It included twenty patients with distal tibiofibular syndesmotic injury. They were operated upon by suture button fixation at Al-Azhar University Hospital (New Damietta) and were assessed clinically and radiologically directly and followed up over four months after surgery.
Results: Patient’s age ranged from 25-54 years with the mean value of 39±7.3 years. Female patients were 15 (75%). The left side was 14(70%) affected in patients, while the right 6 patients (30%). The functional outcomes were 95% excellent and 5% good. There was no post-operative complication except one case complicated with superficial infection and another case complicated with wound dehiscent. All cases were operated on the same day of fracture except two cases presented by severe edema and skin bullae and the operation was delay one week until the edema subsided. Time to full weight bearing ranged 5 to 6 weeks.
Conclusion: The suture button technique is considered a viable alternative option to replace screw fixation for syndesmosis injuries. It normalizes the distal tibiofibular syndesmosis that remains normal throughout the follow up duration.

Authors: Mahmud Khalil  , Elsokkary Ismail N. , Wael Sayed  
Published: April 2023

Background: Hypertrophic obstructive cardiomyopathy (HOCM) is a cardiac condition of an abnormal interventricular septum (IVS) thickening. It is due to an autosomal dominant mutation in sarcomeric protein genes. It had many phenotypes with different distribution of myocardial hypertrophy. Septal myectomy remains the treatment of choice for hypertrophic obstructive cardiomyopathy resistant to medical therapy. However, controversy exist regarding standard treatment option(s).
Description of the Case: Here we described a case of 47-year-old patient admitted with diagnosis of acute coronary syndrome, with typical chest pain of angina class II, shortness of breath class-II (NYHA), smoker on regular renal hemodialysis. Echocardiography showed HOCM, IVS thickening, normal Left ventricle global systolic function and mild to moderate eccentric regurge. Coronary angiography revealed normal left main with total (LAD) proximal occlusion, proximal and mid (LCX) (50%) occlusion, first (OM) mid (90%) lesion, (RCA) dominant with non-flow limiting lesions. He was submitted to open heart surgery with four grafts, sub-valvular myomectomy, and successful myomectomy. Distal anastomosis was done first then myomectomy then proximal anastomosis. Patient extubated after (9) hours with stable hemodynamics and complete neurological condition, with accepted drains output. He gradually weaned from inotropic support and chest drains removed on 3rd postoperative day. All lines and pacemakers were removed, the wound was dry with stable sternum and improvement of all symptoms. Then discharged home after 9 days of hospital stay on medical treatment. Postoperative echocardiography showed significant improvement.
Conclusion: Surgical treatment is the standard option in treatment of HOCM to improve symptoms.

Authors: Al-Azzony Ahmed Mohamed Ahmed , Attia Mohamed Adel , Nagib Khaled Ebrahim , Gad Ayman Ahmed 
Published: April 2023

Background and Aim: Fragmented QRS (fQRS) are electrocardiographic signals reflecting altered ventricular conduction around regions of a myocardial scar and/or ischemia. However, it could be presented in normal healthy individuals. But, its incidence and its role in prediction of cardiac disease is not yet addressed. This study aiming to assess the left ventricular (LV) functions in patients with apparent normal LV functions with fQRS using two-dimensional (2D) speckle tracking echocardiography.
Patients and Methods: This cross-sectional study take place from March to October 2020. Fifty non cardiac patients who undergo preoperative cardiac assessment of non-cardiac surgery at cardiology department were included. All subjects are submitted to full history taking, complete general and local examinations, twelve lead ECG searching for fQRS complex and exclude ischemia and arrhythmia, and transthoracic echocardiography to assess LV functions as described previously.
Results: 36% fQRS complex was in anterior lead, 50% were in Inferior lead and only 14 % was in Lateral lead. Mean EF was 58.9 ± 5.8%, ranging from 55 to 65, FS was 26.7±1.9%, with range of 24 to 40%. LVEDD 4.5±0.7cm, LVESD was 3.3±0.4cm, Intraventricular septum was 10.1±0,6 mm and Posterior wall thickness 9.6±07 mm. Left ventricular longitudinal strain in 2 chamber apical view was 16.4±3.3%, 4 chamber apical view was 16.7±3%, apical long axis view was 17.7±3.5% and average LV GLS was 18.1±2.9%. There were 15 cases abnormal LV diastolic function according to E/e` ratio and 9 cases according to LV-GLS. There was statistically significant different between assessment of LV function by 2D echocardiography and speckle tracking.
Conclusion: The presence of fQRS on standard electrocardiography in apparently healthy people with preserved EF is associated with some sort of subclinical LV dysfunction and two-dimensional speckle tracking is more accurate and sensitive than two-dimensional echocardiography in detection of those patients.

Published: April 2023

Background: This study aims to evaluate the effect of intraoperative fluid therapy on intensive care process and first 90-day morbidity and mortality in patients undergoing lung transplantation.
Methods: Between March 2013 and December 2020, a total of 77 patients (64 males, 13 females; mean age: 47.6±13.0 years; range, 19 to 67 years) who underwent lung transplantation were retrospectively analyzed. The patients were divided into two groups according to the amount of fluid given intraoperatively: Group 1 (<15 mL/kg-1/h-1) and Group 2 (>15 mL/kg-1/h-1). Demographic, clinical, intra- and postoperative data of the patients were recorded.
Results: Less than 15 mL/kg-1/h-1 f luid w as a dministered t o 75.3% (n=58) of the patients (Group 1) and 24.7% (n=19) were administered more than 15 mL/kg-1/h-1 (Group 2). In t erms of native disease, the rate of diagnosis of chronic obstructive pulmonary disease and idiopathic pulmonary fibrosis was higher in Group 1, and the rate of other diagnoses was higher in Group 2 (p<0.01). The ratio of women in Group 2 was higher (p<0.05), while the body mass index values were significantly lower in this group (p<0.01). The erythrocyte, fresh frozen plasma, platelet, crystalloid and total fluid given in Group 2 were significantly higher (p<0.001). Inotropic/vasopressor agent use rates and extracorporeal membrane oxygenation requirement were significantly higher in Group 2 (p<0.01). Primary graft dysfunction, gastrointestinal complications, and mortality rates were also significantly higher in Group 2 (p<0.05).
Conclusion: The increased intraoperative fluid volume in lung transplantation is associated with primary graft dysfunction, gastrointestinal complications, and mortality rates.

Background: This study aims to evaluate the early extubation rate and the factors affecting early extubation in pediatric patients undergoing cardiac surgery.
Methods: Between August 1st, 2020 and December 1st, 2021, a total of 528 pediatric patients (264 males, 264 females; median age: 4 months; range, 2 days to 24 months) who were followed in the pediatric cardiac intensive care unit after congenital heart surgery were retrospectively analyzed. Demographic and clinical characteristics of the patients including operation and intensive care data were obtained from the medical records. Patients included in the study were categorized into three groups as the group of patients who were extubated in the operating room (fast-track extubation), the group of patients who were extubated in the first 6 h of the operation (early extubation), the group of patients who were extubated after the postoperative 6 h or the group of patients who were not extubated or died (delayed extubation).
Results: Sixty-eight (12.9%) cases had fast-tract extubation, 124 (23.6%) cases had early extubation, and 335 (63.6%) cases had delayed extubation. The median age of the patients in the delayed extubation group was three months, which was significantly lower than those of the other groups (p<0.05). Reintubation rates were 1.5% in the fast-tract extubation group, 2.5% in early extubation group, and 9% in delayed extubation group (p<0.05). The median intensive care unit stay was 3, 5, and 10 days, respectively (p<0.05). Length of hospitalization was significantly higher in the delayed extubation group compared to the other groups (p<0.05). Neonatal age group, Risk Adjustment for Congenital Heart Surgery 1 score >4, Society of Thoracic Surgeons- European Association for Cardio-Thoracic Surgery mortality category >3, cardiopulmonary bypass time >100/min, vasoactive inotrope score >8, acute kidney injury >2, and low weight were found to be independent risk factors for delayed extubation.
Conclusion: Fast-track and early extubation can be successfully applied with low reintubation rates in selected cases with congenital heart surgery. Age, body weight, presence of genetic syndrome, operational risk category, and procedure time may affect the extubation time.

Authors: Mert Duman Zihni , Bayram Muhammed , Timur Barış , Can Kaplan Mustafa , Aksu Timuçin 
Published: April 2023

Background:In this systematic review, we aimed to examine the risk factors and surgical outcomes of gastrointestinal complications using the meta-analysis techniques.Methods:Studies involving patients with and without gastrointestinal complications after cardiac surgery were electronically searched using the PubMed database, Cochrane Library and Scopus database, between January 2000 and May 2022. Some studies on gastrointestinal complications examined only single gastrointestinal complication (only intestinal ischemia, only gastrointestinal bleeding or only liver failure). Studies evaluating at least three different gastrointestinal complications were included in the meta-analysis to reduce the heterogeneity. Cohort series that did not compare outcomes of patients with and without gastrointestinal complications, studies conducted in a country"s health system databases, review articles, small case series (<10 patients) were excluded from the meta-analysis.Results:Twenty-five studies (8 prospective and 17 retrospective) with 116,105 patients were included in the meta-analysis. The pooled incidence of gastrointestinal complications was 2.51%. Patients with gastrointestinal complications were older (mean difference [MD]=4.88 [95% confidence interval [CI]: 2.85-6.92]; p<0.001) and had longer cardiopulmonary bypass times (MD=17.7 [95% CI: 4.81-30.5]; p=0.007). In-hospital mortality occurred in 423 of 1,640 (25.8%) patients with gastrointestinal complications. In-hospital mortality was 11.8 times higher in patients with gastrointestinal complications (odds ratio [OR]=11.8 [95% CI: 9.5-14.8]; p<0.001).Conclusion:The development of gastrointestinal complications after cardiac surgery is more commonly seen in patients with comorbidities. In-hospital mortality after cardiac surgery is 11.8 times higher in patients with gastrointestinal complications than in patients without.

Published: April 2023

Background: This study aims to compare the cerebral, hemodynamic, and metabolic effects of different prime solutions used in patients undergoing coronary artery bypass grafting.
Methods: Between May 2013 and May 2014, a total of 30 patients (25 males, 5 females; mean age: 59.5±9 years; range, 42 to 78 years) who were schedule for elective isolated coronary artery bypass grafting were included in this prospective study. The patients were randomized into three groups: Group 1 (n=10) (ringer"s lactate [RL]), Group 2 (n=10) (6% hydroxyethyl starch [HES] 130/0.4), and Group 3 (n=10) (RL + 6% HES 130/0.4). Hemodynamic parameters, arterial blood gas analyses, hemoglobin, hematocrit, cerebral regional oxygen saturation, urine output and fluid balance were recorded preoperatively, before and after anesthesia, 10 min after the transition to extracorporeal circulation, while weaning from extracorporeal circulation, and at the end of surgery. Preoperatively and on postoperative Day 5, neuron-specific enolase enzyme and S-100 ? protein were assessed. On Day 5 and Week 3 postoperatively, the Standardized Mini-Mental Test was administered to the patients.
Results: The serum neuron-specific enolase enzyme and S-100 ? protein levels of the patients were within physiological limits, and there were no clinical findings suggestive of cerebral damage, or changes in the Standardized Mini-Mental Test scores in any of the patients. There was a decrease of more than 20% of the baseline value of cerebral regional oxygen saturation in a total of four patients, one in Group 1 and three in Group 3. No significant difference was observed among the groups in terms of the other parameters.
Conclusion: The prime solution content has no effect on the development of cerebral damage after cardiopulmonary bypass, and the main factor in preventing the development of cerebral damage was the preservation of cerebral perfusion, which can be achieved by monitoring cerebral perfusion in these patients.

Susceptibility Comparison of Bumblebee and Honeybee to Acetamiprid and Imidacloprid
Authors: Nasir Muhammad 
Published: April 2023

midacloprid and acetamiprid are neonicotinoid insecticides introduced in the market for the control of insect pests of agricultural crops, but unfortunately these insecticides are causing harmful effect on non-target organisms including honeybees and bumblebees. Insecticides of this group effect acetylcholine nicotinic receptors. Apis mellifera, the European honeybee and Bombus haemorrhoidalis are important pollinators for wild and managed crops in Pakistan, but unfortunately their population is declining day by day at alarming rate. This study was design to find out the susceptibility level and insecticidal toxicity comparison on A. mellifera and B. haemorrhoidalis to acetamiprid and imidacloprid under controlled laboratory conditions by using contact and oral exposure methods. The results of oral method by using sugar solution showed that honeybee is more susceptible as compared to bumblebee on both insecticides. Maximum mortality i.e. 20%, 35%, 66%, in honeybee and 16%, 29%, 45% in bumblebee workers at acetamiprid and at imidacloprid 46%, 67%, 83% in honeybee and 34%, 56%, 72% in bumblebee were observed respectively after the exposure of 3hrs. 6hrs. and 24hrs. Similar susceptibly results were found on pollen and contact method. Overall results demonstrate that these both neonicotinoid insecticides are toxic for bumblebees and honeybees, and honeybee workers are more susceptible as compared to bumblebee workers at company recommended field realistic dose.
