Antibiotic-induced Toxic Epidermal Necrolysis - A Case Report.

Toxic epidermal necrolysis (TEN) is severe cutaneous hypersensitivity reaction characterized by necrosis of the epidermis and detachment of the epidermis and dermis that usually occurs as an idiosyncratic reaction to certain drugs. We report the case of a patient admitted to our Intensive Care Unit after an above-the-knee amputation who developed toxic epidermal necrolysis, possibly resulting from antibiotics therapy. Therapy included a combination of intravenous immunoglobulin with gentle early debridement of necrotic skin areas followed by wound coverage with a synthetic cover (Aquacel Ag®). This case report suggests that intensive wound management together with intravenous immunoglobulin might be beneficial in the treatment of patients with TEN.

Laparoscopic Treatment of Morgagni Hernia: Report of Three Cases.

We report on three cases of diaphragmatic (Morgagni) hernia with different clinical presentation. It is important to consider the possibility of this rare but potentially very dangerous condition in patients with respiratory problems and pain in the upper abdomen. Before laparoscopy, two different approaches were used in diaphragmatic hernia operations (abdominal and thoracic approach). Laparoscopy has brought significant changes in the treatment of diaphragmatic hernia. It is important to stress that laparoscopic diaphragmatic surgical therapy uses stronger mesh than the mesh used to repair an inguinal hernia.

Intraoperative volume restriction in esophageal cancer surgery: an exploratory randomized clinical trial.

AIM: To investigate whether the fluid volume administered during esophageal cancer surgery affects pulmonary gas exchange and tissue perfusion. METHODS: An exploratory single-center randomized clinical trial was performed. Patients with esophageal cancer who underwent Lewis-Tanner procedure between June 2011 and August 2012 at the Department of Thoracic surgery "Jordanovac", Zagreb were analyzed. Patients were randomized (1:1) to receive a restrictive volume of intraoperative fluid (≤8 mL/kg/h) or a liberal volume (>8 mL/kg/h). Changes in oxygen partial pressure (Pao2), inspired oxygen fraction (FiO2), creatinine, and lactate were measured during and after surgery. RESULTS: Overall 16 patients were randomized and they all were analyzed (restrictive group n=8, liberal group n=8). The baseline value Pao2/FiO2 ratio (restrictive) was 345.01±35.31 and the value six hours after extubation was 315.51±32.91; the baseline Pao2/FiO2 ratio (liberal) was 330.11±34.71 and the value six hours after extubation was 307.11±30.31. The baseline creatinine value (restrictive) was 91.91±12.67 and the value six hours after extubation was 100.88±18.33; the baseline creatinine value (liberal) was 90.88±14.99 and the value six hours after extubation was 93.51±16.37. The baseline lactate value (restrictive) was 3.93±1.33 and the value six hours after extubation was 2.69±0.91. The baseline lactate value (liberal) was 3.26±1.25 and the value six hours after extubation was 2.40±1.08. The two groups showed no significant differences in Pao2/FiO2 ratio (P=0.410), creatinine (P=0.410), or lactate (P=0.574). CONCLUSIONS: Restriction of intraoperative applied volume does not significantly affect pulmonary exchange function or tissue perfusion in patients undergoing surgical treatment for esophageal cancer.

Application of the procedural consolidation concept to surgical treatment of children with epidermolysis bullosa: a retrospective analysis.

AIM: To assess the efficacy of the procedural consolidation concept (PCC) at reducing the number of sessions of general anesthesia necessary for treating children with epidermolysis bullosa (EB). METHODS: We examined the records of children treated at Children's Hospital of Zagreb between April 1999 and December 2007. Children treated before the introduction of PCC in January 2005 (n=39) and after (n=48) were analyzed in order to determine the effect of PCC on the occurrence of complications, days of hospitalization, and number of hospitalizations. RESULTS: During the study period, 53 patients underwent 220 sessions of general anesthesia for a total of 743 surgical interventions per session. Before the introduction of PCC (n=39 patients, 83 sessions), the median number of interventions per session was 2 (range 1-5), and after the introduction of PCC (n=48 patients, 137 sessions) it was 4 (range 3-7, P<0.001). After the introduction of PCC, the median number of complications per anesthesia session increased from 2 (range 0-10) to 3 (range 0-10) (P=0.027), but the median number of complications per surgical procedure decreased from 1 (range 0-10) to 0.6 (range 0-2.5) (P<0.001). PCC lengthened each anesthesia session from a median of 65 minutes (range 35-655) to 95 minutes (range 50-405), (P<0.001). Total length of hospitalization was similar before (median 1, range 1-4) and after (median 1, range 1-3) introduction of PCC (P=0.169). The number of hospitalization days per procedure was 3 times lower after the introduction of PCC (median 0.3, range 0.2-3) than before (median 1, range 0.75-1.7) (P<0.001). CONCLUSION: PCC should be considered an option in the surgical treatment of children with EB.

Respiratory tract involvement in a child with epidermolysis bullosa simplex with plectin deficiency: a case report.

We report a rare case of a child with epidermolysis bullosa simplex (EBS) with plectin deficiency but without muscular dystrophy, with severe lesions of the oral cavity, oropharyngeal, hypopharyngeal, laryngeal, tracheal and bronchial mucosa. Case report and a review of the world literature are used. The literature review revealed only five similar patients with EBS without muscular dystrophy complicated by respiratory involvement. This paper highlights the potentially serious complications of the EB in the form of breathing, swallowing and speech difficulties and describes the specific problems encountered in the treatment of this patient. Epidermolysis bullosa (EB) is a group of severe hereditary diseases, primarily of the skin, but which can also involve the respiratory and gastrointestinal tract mucosa. Respiratory tract involvement is usually only found in certain types of EB. The oral cavity and oropharynx are involved more frequently than the hypopharynx, larynx and trachea. Involvement of laryngeal and tracheal mucosa is generally associated with an increased morbidity and mortality, numerous complications and therapeutic difficulties, and is more common in junctional EB and dystrophic EB than in EBS. We present a rare case of a child with EBS and plectin deficiency with pronounced lesions of respiratory tract mucosa from the oral cavity to the bronchi and even extending into the trachea. Deciding on tracheotomy requires thorough consideration and should not be taken lightly.

Central venous catheters for chemotherapy of solid tumors--our results in the last 5 years.

Central venous catheters provide an easy access for intravenous medications. Having a central line in place will relieve a child from the discomfort and danger of multiple regular intravenous lines for chemotherapy. The use of indwelling central venous catheters has become commonplace in the management of children undergoing oncological treatment. There are two types of central lines commonly used. There are Broviac catheters and Port-A-Cath (PAC) catheters. In the last 5 years we inserted 194 catheters in 175 children. We inserted 121 Broviac catheters and 73 PAC catheters. During the follow up of 39382 catheter days 44 complications were observed. In Broviac group the median follow up was 155 days and in PAC group was 230 days. We observed differences in the incidence between two devices. In Broviac group infections were more frequent and in PAC group other complications were more frequent than infections.

Evaluation of bacteremia in a pediatric intensive care unit: epidemiology, microbiology, sources sites and risk factors.

Bacteremia is a common cause of morbidity and mortality in children treated in pediatric intensive care unit (PICU). We have investigated the causative agents of bacteremia in our PICU over a one-year period, to determine mortality associated with such infection and identify the dependent predictors for morbidity and mortality. From 1 January till 31 December 2006, 479 patients were admitted in the PICU and 379 blood culture samples were taken. Samples were incubated in the BACTEC 9050 System, and isolates identified by routine microbiological methods. A pair of samples taken for aerobic and anaerobic culture were statistically regarded as one sample. Data collected from the medical records of each patient were recorded onto standardized collections sheets and included demographic information, predisposing conditions, source(s) of infection, important clinical and laboratory parameters at the time of infection, and microbiological data. Based on these data, positive blood cultures were classified as either contaminants or true bacteremias. During a year period, 117 episodes of bacteremia were documented in 72 patients. The most frequent isolates were the coagulase-negative staphylococci 32.2% (39), followed by Candida spp. 30.5% (36). The mean white blood cell count (WBC) on the day of bacteremia was 15.2 x 10(9)/L (range 0.1-48.0 x 10(9)/L), and 3.3% of episodes occurred in neutropenic (WBC count < 1 x 10(9)/L) children. The mean temperature on the day of infection was 38.2 +/- 1.1 degrees C (range, 34-41 degrees C). Some newborns 23% (n = 5) had a significantly lower mean temperature (p < 0.02) and lower mean WBC count (p < 0.05) than older children. Hemodynamic instability was noted in 11% of bacteremic episodes. Among all bacteremias, intravascular catheters were implicated in 22.6%, pneumonia in 20.4%, genitourinary tract in 14.2%, surgical wounds in 11.7% and, gastrointestinal tract in 9.8%. Seven patients died because of sepsis. Early diagnosis, prompt blood culture reports, followed by appropriate antibiotic treatment is essential in reducing mortality in such patients. Short hospital stay and restricted use of invasive devices should be the aims to reduce the risk of bacteremia during the stay in the PICU.
