In Situ Surgery: Is It Safe ? (Experience with 60 cases)
AM El Sadat, M Ebrahim, M Emam, NA Abdelaal
Annals of Pediatric Surgery , 2010,
Abstract: Background/Purpose: Neonatal surgical unit (NSU) is the area of a hospital where sick babies having surgical problem go once they are born. Performing in-situ surgery (ISS) in the NSU is relatively a new concept that is gaining popularity in the last decade. Critically ill neonates who are too ill to transfer to the operating room can undergo safe surgery in the NSU environment of a fully-equipped pediatric hospital. Transfer of the critically ill neonates is time consuming, utilizing manpower and requiring suitable portable ventilators and extensive monitoring equipments. Materials & Methods: This is a prospective study conducted on 60 neonates admitted in the surgical neonatal unit of the Cairo University pediatric hospital (Abou-Elrish) and where subjected to surgical procedures in the unit itself. The patients were categorized into 3 groups: The First group was the group at the beginning of the study for which minor procedures were selected. The second group was those neonates that were operated upon on emergency base for which transfer could be hazardous. The last group included those patients on high settings of ventilation and critically ill neonates with extensive monitoring. Results: There was no mortality in the study related to the procedures itself. Group I patients: the time of the surgical procedures was longer than that in the OR and no increase in the infection rate was noticed. Group II in which emergency procedures were carried on showed also increase in operating time but better perioperative circumstances regarding secondary insult to viable structures & less infection rate. Group III: no significant change in outcome in comparison to cases transferred to OR except that the perioperative circumstances were better for the surgeon, anesthesiiologist & nursing teams. Conclusion: NSU is a safe place for performing in-situ surgery (ISS) without increased risk of infection. Successful operative intervention within NSU requires good planning and cooperation between anesthesiologist, surgeons, neonatologist and nursing staff. Maximum benefit is observed in neonates who have definite risk attached to transfer to operating room. Index Word: In-Situ Surgery (ISS) – Neonatal Surgical Unit (NSU).

Abstract: Introduction: Single or double venous anastomosis in free flap in general and ALT, in particular, is still a matter of debate between micro vascular surgeons. In this study, we will present our experience in single vein anastomosis versus double venous anastomosis in ALT perforator flap used in leg and foot reconstruction as regarding flap outcome, complications, operation time and the need for re-exploration. Patient and Methods: We retrospectively evaluate 60 patients with post traumatic foot and leg defects in the period between January 2014 and January 2018 where free ALT flap was done. The patients were divided into two groups, Group 1 where single vein anastomosis was done and Group 2 where double venous anastomosis was done; we utilize the deep venous system for the anastomosis in all cases. Results: Complete flap survival noticed in 56 cases (93.3%), defect size ranged from 70 to 200 cm (mean 126.35 ± 33.78). There was no difference between the 2 groups as regarding Flap survival, hospital stay, flap complications, donner site morbidity and vascular insufficiency. There is statistically significant difference between both groups as regarding Ischemia time, Operation time, and overall re-exploration rate. Conclusions: Our study suggests that the use of a single venous anastomosis in the venous drainage of anterolateral thigh free flaps is as safe and feasible as the two veins anastomoses.

Abstract: Background: Internal splintage of open tibial fractures had gained acceptance as a preferred method of early stabilization of such injuries. Patients and Methods: Fifty-five patients had been operated upon. They were followed from July 2008 to March 2013 (56 months) with an average time of 39 months. The final results had been evaluated through a scheme including 7 parameters: pain, union, malunion, infection, range motions of nearby joints, implant and technical failure and activity and returning to the same work. Results: According to previous parameters, union was achieved in 52 cases (94.5%) at an average time of 20 weeks (16 - 52 weeks) with 5.5% incidence of nonunion. Excellent and good ranges of knee and ankle motions were achieved at final follow-up visit in 49 cases (89.09%). The incidence of complication was acceptable mainly malunion 7.3%, deep infection 12.7%, implant and technical failure 9.1% full activity and returning to the same work achieved in 89.1%. The overall net results of our series are as follows: excellent—19 cases (34.5%), good—27 cases (49.1%), fair—6 cases (10.9%) and poor—3 cases (5.5%). Conclusion: Utilizing unreamed interlocking nail for open tibial fractures is a good method of treatment particularly those of grade (II), and (IIIA).

Abstract: Sa？etak Osamnaest bivola s traumatskom upalom kapure i potrbu？nice pretra？eno je ultrazvukom u razdoblju od dvije godine. Deset zdravih bivola poslu？ilo je kao kontrolna skupina za klini？ke pokazatelje i ultrazvu？nu procjenu stanja kapure. Kapura je bila pretra？ena konveksnim pretvornikom od 3,5 MHz. Za razliku od kontrolne skupine, ？ivotinje s traumatskom upalom pokazivale su povi？enu rektalnu temperaturu, gubitak apetita, smanjeni ili izostali motilitet buraga, povratnu nadutost te pozitivni nalaz pretragom na bolnost i prisutnost metala. U dvanaest bivola ustanovljeno je jedno strano tijelo, a u njih ？est vi？e stranih tijela. Ustanovljena je hiperehogenost s artefaktima nalik repu kometa (n = 13) ili s akusti？nim sjenama (n = 5). Akusti？ne sjene bile su uo？ene samo kod stranih tijela smje？tenih uz trbu？nu stijenku. Ona su probila trbu？nu stijenku u pet bivola kod kojih je ustanovljena lokalizirana oteklina i fistula na kranioventralnom dijelu trbuha. Strana tijela bila su dokazana na lijevoj strani u 10, a na desnoj strani u osam bivola. Perforacija mekih tkiva stranim tijelima bila je popra？ena upalom u 14 i nastankom apscesa u ？etiri ？ivotinje

Abstract: Sa？etak Eighteen buffaloes with traumatic reticuloperitonitis were examined by means of sonography during a 2 year period. Ten healthy buffaloes served as a control group for clinical parameters and ultrasonographic assessment of the reticulum. The reticulum was examined with a 3.5 MHz convex transducer. The patients, as opposed to the control group, showed an increased rectal temperature, inappetence, reduced or absent ruminal motility, recurrent tympany, and positive metal detector and pain tests. Twelve buffaloes had single and 6 had multiple foreign bodies. Their sonographic appearance was hyperechogenic with comet tail artifacts (n = 13) or with acoustic shadows (n = 5). Acoustic shadows were only observed in foreign bodies located near the abdominal wall. They perforated the abdominal wall in 5 buffaloes presented with localised swellings and fistulas in the cranioventral abdomen. The foreign bodies were detected from the left side in 10 and from the right side in 8 cases. Perforation of soft tissues by foreign bodies was accompanied with inflammation in 14 and abscess formation in 4 cases

Abstract: Background: Traumatic flail chest is a serious injury that can impair ventilation and affect patient outcome. Thoracic epidural analgesia is the gold standard to provide adequate analgesia in flail chest, however, it may be unavailable in some patients due to coagulopathy, failure or difficult insertion. We compared between parenteral dexmedetomidine and thoracic epidural block with plain local anesthetic in flail chest cases. Patients and methods: fifty eight trauma patients with flail chest randomly allocated into either Group E (n = 29): epidural group, patients received mid-thoracic epidural analgesia using 6 ml mixture of 0.125% bupivacaine and 2 μg/ml fentanyl, which followed by continuous infusion of 6 ml/hour; Group D (n = 29): dexmedetomidine group, patients received loading dose of dexmedetomidine 1 μg/kg over 30 min, after a continuous infusion at a rate of 0.5 μg/kg/hr. The primary outcomes were to assess the effect of analgesic type on ventilation (PaO2/FIO2 ratio, PaCO2). The secondary outcomes were to compare analgesic effect, hemodynamics, the need for ventilation and ICU stay. Result: PaO2/FIO2 ratio was significantly higher in epidural group and PaCO2 was significantly lower in epidural group (p value < 0.05). The incidence of mechanical ventilation was significantly lower in epidural group than in dexmedetomidine group (6 patients group versus 13 patients, p value < 0.04). Mean arterial blood pressure was significantly lower in dexmedetomidine group than in epidural group (94.3 ± 6.84 mmHg versus 102 ± 5.72 mmHg, p value < 0.001). Moreover, heart rate was significantly lower in dexmedetomidine group than epidural group (89.97 ± 6.22 bpm versus 96.07 ± 9.3 bpm, p value = 0.004). VAS was significantly lower in epidural group (p value < 0.001). Throughout different measuring points, RAMSAY score was significantly higher in dexmedetomidine group. Conclusion: Epidural analgesia is more effective than parenteral dexmedetomidine in flail chest, but dexmedetomidine can represent a good alternative if epidural is not possible.

Abstract: A series of metal oxides hollow spheres (Cr2 O3 , α-Fe2 O3 , Co3 O4 , NiO and ZnO) have been fabricated using the glucose derived-carbonaceous spheres as sacrificial templates and the metal chlorides as precursors for the metal oxides in a sacrificial templating process. Heating of an aqueous solution of the metal chloride and glucose in an autoclave at 180 oC affords - as indicated by transmission electron microscopy (TEM) - a nanospherical composite consisting of a metal precursor shell sheathing a carbonaceous core. Consequently, hollow crystalline oxides spheres are obtained by removal of the carbonaceous cores through calcination in air. Correlations between the particle size and the various synthesis conditions such as glucose concentration, the molar concentration ratio between glucose and metal chloride, temperature, reaction time and the addition of acetic acid as a catalyst are uncovered. The obtained metal oxides hollow spheres were characterized by means of scanning electron microscopy (SEM), transmission electron microscopy (TEM), x-ray powder diffraction (XRD), infrared spectroscopy (IR), and nitrogen adsorption/desorption isotherms (BET).

Abstract: Among people that might take a large amount of sucralose, are diabetic people who are attempting to modify their carbohydrate intake. The objective of this study is to evaluate the impact of sucralose; an artificial sweetener derived from sucrose, at a dose approximately twice the ADI on hyperglycemia, hyperlipidemia and oxidative stress in diabetic rats. Diabetes was induced in male albino rats after an intraperitoneal streptozotocin injection (65 mg/kg body weight). Animals with fasting blood glucose levels ≥250 mg/dl were considered diabetics. Sucralose was dissolved in water and administered to rats daily by oral gavages during a period of 6 weeks at a dose of 11 mg/kg body weight. Animals were divided into 4 groups and treated in parallel for 6 weeks. Control: rats received distilled water, Sucralose: rats received sucralose, Diabetic: diabetic rats received distilled water, Diabeticrats + Sucralose: diabetic rats received sucralose. The administration of sucralose to diabetic rats provoked a significant decrease (P < 0.05) of serum glucose and triglyceride levels, a significant increase (P < 0.05) of total cholesterol, low density lipoprotein-cholesterol (LDL-C), and high density lipoprotein-cholesterol (HDL-C), while has no effect (P > 0.05) on insulin, compared to their respective values in diabetic rats receiving distilled water. Biochemical analysis in brain and testis tissues showed that sucralose has no effect (P > 0.05) on superoxide dismutase (SOD), catalase, glutathione peroxidase (GSH-Px), and glucose-6-phosphate dehydrogenase (G-6-PDH) activities, and glutathione content (GSH), while reduced thiobarbituric acid reactive substances level (TBARS) (P < 0.05), compared to their respective values in diabetic rats receiving distilled water. It could be concluded that consumption of sucralose didn’t induce oxidative stress, has no effect on insulin, reduce glucose absorption and intensify hypercholesterolemia in STZ-induced diabetic rats. Accordingly it is advised that diabetic people consuming high amount of sucralose must check their lipid profile to avoid diabetic complications.

Abstract:

Symptoms suggesting occurrence of otitis media (OM) in infants and young children are not always right. Objective: Assessment of those infants and children with symptoms suggesting otitis media. Patients & Methods: 113 infants and children were complaining of ear symptoms suggesting otitis media as well as 63 infants and children of same age and sex were not complaining of any of these symptoms suggesting otitis media, were fully investigated prospectively, by full clinical and ear, nose examination as well as swab culture from the ear discharge. Results: There was no statistical significant difference between the prevalence of otitis related symptoms and the risk factors in both groups. There was no correlation found between the otoscopic diagnosis of OM and the main complaint suggesting OM in the patients, mainly ear pain and ear discharge. There was a positive significant correlation between otoscopic diagnosis of OM and fever, diarrhea, and bronchiolitis (significance was at 0.01, 0.01 and 0.05 levels respectively). Conclusion: Otoscopic examination is very important in any infant or child complaining of ear pain, ear discharge or complaining of otitis related symptoms.
