RESUMEN

PURPOSE: Percutaneous nephrolithotomy (PCNL) is the preferred surgical treatment in many cases of kidney stones which is performed in different positions such as prone, lateral, and supine. This study was designed to evaluate whether patient position (lateral versus . prone) has an effect on the need for analgesia and onset of pain after surgery. MATERIALS AND METHODS: Patient with confirmed kidney stones (size ? 2 cm) who were candidates for PCNL were enrolled in this study. The required biochemical analyses were performed preoperatively. All patients  underwent spinal anesthesia by the same anesthesiologists and then were randomly divided into two separate groups as lateral (L) and prone (P) positions. The operations' start and end time, required time for proper access into target calyces, additional need for analgesic or cardiac drugs, duration of analgesia, and onset of pain after PCNL were carefully recorded and then compared between the two groups. RESULTS: In total, 51 patients were evaluated of whom 39 were men and 12 were women. Mean duration of analgesia after PCNL surgery in P group (173 ± 8 min) was significantly longer than in L group (147±12 min) (P = .001). Furthermore, the amount of ephedrine usage in L group (3.6 ± 1.5mg) was significantly lower than in the P group (16.4 ± 12mg), suggesting more hemodynamic variations in the P group during the operation. CONCLUSION: Our randomized control trial study shows that choosing the optimal position in the PCNL technique depends on  patient's condition. If hemodynamic control is of matter to the anesthesiologist, then lateral position is more appropriate. However, if control of pain and longer time of analgesia are important,  prone position may be preferred.

RESUMEN

Sturge-Weber syndrome (SWS) is a neurocutaneous disorder, characterized by leptomeningeal angiomas involving the oral cavity, trachea, larynx, and face. Herein, we present a case of vitrectomy in a seven-year-old boy with SWS. The patient showed hemangioma on the left side of his face, as well as mental retardation and epilepsy. Preoperative examination revealed no apparent hemangioma in the oral cavity, pharynx, larynx, or trachea. However, he was predicted to have difficult airway intubation, as the oral cavity was smaller than the normal size. The minimum Mallampati score was 3-4 due to macroglossia. First, we applied awake intubation, but he failed to follow the commands. We proceeded to general anesthesia with propofol and did not use any muscle relaxants to maintain spontaneous breathing. A laryngeal mask airway was inserted to minimize any harm to possible oral angiomas. The patient was hemodynamically stable and extubated without any complications, such as bleeding or respiratory problems.

RESUMEN

BACKGROUND: Malnutrition is very common among chronically hospitalized patients, especially those in the intensive care unit (ICU). Identifying the patients at risk and providing suitable nutritional support can prevent and/or overcome malnutrition in them. Total parenteral nutrition (TPN) and partial parenteral nutrition (PPN) are two common routes to deliver nutrition to hospitalized patients. We conducted a multicenter, prospective double blind randomized controlled trial to evaluate the benefits and compare their adverse effects of each method. MATERIALS AND METHODS: 97 patients were enrolled and divided into two groups based on the inclusion criteria. Serum protein, serum albumin, serum transferrin, and total lymphocyte count were measured on days 7 and 14. RESULTS: We did not find any statistically significant differences in clinical status or laboratory values between the two groups but there were significant improvements in measured lab values between days 7 and 14 (p<0.005) indicating improved nutritional status in each groups. CONCLUSION: This study shows that both TPN and PPN can be used safely in chronic ICU patients to provide nutritional support and prevent catabolic state among chronic critically ill patients. We need to develop precise selection criteria in order to choose the patients who would benefit the most from TPN and PPN. In addition, appropriate laboratory markers are needed to monitor the metabolic requirements of the patients and assess their progress.

RESUMEN

BACKGROUND: A detrimental effect of commonly used anesthetics on the neurodevelopmental and behavioral parameters has long been shown in young animals subjected to early childhood anesthesia. Epidemiologic studies suggest the possibility of a modestly elevated risk of adverse neurodevelopmental outcomes in children exposed to anesthesia during early childhood. However, these results are still preliminary and inconclusive. AIM: To further elucidate the probability of occurrence of such adverse outcomes, we evaluated cognitive performance of children who underwent general anesthesia early in their childhood. METHOD: One hundred and fifteen children aged 5-16 years with established glaucoma were included in the study. Of these, 68 children had a history of at least one general anesthesia with sevoflurane before age 3. Phonemic and semantic verbal fluency, and forward and backward digit span tests were performed to evaluate cognitive function in the study subjects. RESULTS: The two-way anova revealed that all these variables showed significant changes in various age groups, but they were comparable among subjects with no, single, or multiple childhood anesthesia. CONCLUSION: It can be concluded that brief periods of anesthesia with single anesthetic sevoflurane may be safe for children under age 3.

RESUMEN

BACKGROUND: To describe the mental health status of 78 child and adolescent survivors of post-war landmine explosions. METHODS: Child and adolescent survivors of landmine explosions who were younger than 18 years old at the time of the study were identified and enrolled in this study. The mental health status of the participants was assessed by general health assessment and psychiatric examinations. Psychiatric assessment and diagnosis were undertaken using the Diagnostic and Statistical Manual for mental disorders (DSM-IV) criteria. A psychiatrist visited and interviewed each survivor and identified psychiatric disorders. RESULTS: Seventy-eight child and adolescent survivors with a mean age of 16.11 ± 2 years old were identified and agreed to participate in the study. The mean age of the victims at the time of injury was 8.2 ± 3.12 years old (range 2-15). Thirty-seven (47.4 %) of the adolescent survivors suffered from at least one psychiatric disorder. Twenty-nine survivors (37.1 %) were newly diagnosed and needed to start medication and psychiatric treatment. The most common findings were anxiety disorders (34.6 %), including posttraumatic stress disorder (PTSD) in 20 (25.6 %), and generalized anxiety disorder (GAD) in 7 (9 %) subjects. Mild-Moderate depression was found in 5 (6.4 %) subjects. No personality disorders were observed, and two patients suffered from mental retardation. The study results revealed a significant association between age of casualty, duration of injury and limb amputation, and types of psychological disorders. CONCLUSION: Child and adolescent survivors of landmine explosions had a high prevalence of psychiatric disorders.
