Opioid-free anesthesia under single injection paravertebral block combined with sevoflurane for pediatric renal surgery: a prospective observational pilot study.

Even though several studies have demonstrated the effectiveness of opioid free anesthesia (OFA) strategies in pediatric patients, OFA has not been studied in pediatric renal surgery. We, therefore, conducted a prospective observational pilot study on a total of 26 children to assess the feasibility and efficacy of using a single injection ultrasound-guided paravertebral block (PVB) at T10 level with 0.4 mL/kg bupivacaine 0.25% in combination with sevoflurane as an OFA technique in elective open renal surgery. A successful PVB (defined in terms of both hemodynamic change after the skin incision and the use of rescue analgesia) was observed in 25 children (96%). The interval between PVB and skin incision was 21 min [IQR (18-25)]. End tidal sevoflurane concentration was 2.1% [IQR (1.8-2.4)]. The median time between extubation and waking was 2.5 min [IQR (1-4)]. The median Face, Legs, Activity, cry, Consolability score in post-anesthesia care unit was 1.00 [IQR (0-2)]. Blood pressure falls were not significant at different measurement times. None of the patients had complications related to PVB, and only one patient had post-operative vomiting. PVB is an attractive method that can procure an effective OFA in combination with sevoflurane in pediatric renal surgery.

Nebulized ketamine to avoid mechanical ventilation in a pediatric patient with severe asthma exacerbation.

Asthma is a major cause of morbidity and mortality despite advances in outpatient treatment. Sometimes, children fail to respond to standard treatment and can potentially require mechanical ventilation. We describe a case of a 26-month-old girl with a severe asthma exacerbation successfully managed by ketamine administration via nebulization route that permitted to avoid mechanical ventilation. Nebulized ketamine might be a reasonable option to avoid mechanical ventilation in children who fail to respond to standard treatment of severe asthma exacerbation.

Congenital cystic adenomatoid malformation - dangers of misdiagnosis: a case report.

BACKGROUND: Congenital cystic adenomatoid malformation is a rare pulmonary malformation, but is the most common lung malformation observed in children. In developing countries, such as Morocco, prenatal diagnosis is missing. Congenital cystic adenomatoid malformation may occur after birth in the presence of complications and needs a computed tomography scan for confirmation. However, our lack of awareness of this malformation has been responsible for a late and wrong diagnosis along with therapeutic errors. We report the first case in Morocco where diagnosis is confirmed by histology after death. CASE PRESENTATION: A 10-month-old Arab boy was prescribed various antibiotics (including anti-staphylococcal) and endured repeated chest drainages, leading to his death just after radiological diagnosis and instant surgery. CONCLUSIONS: The goal of this case report is to firmly express the need for both pediatricians and radiologists to enlarge diagnosis investigations, especially of congenital or constitutional entities in children, as soon as recurrence of respiratory distress and pulmonary infections are manifested. We also emphasize this important entity because of its frequency, to avoid the eventual therapeutic errors.

Hydatid cyst surgery complicated by hemorrhage resistant to activated recombinant factor VII, in a hemophiliac A patient with an inhibitor.

Factor VII is a new coagulation factor replacement therapy. It has permitted the practice of invasive procedures which were up until recently associated with a huge risk of bleeding in patients with hemophilia with inhibitors. Our case illustrates factor replacement therapy failure in a 13-year-old child operated on for hepatic cysts associated with a pelvic cyst. Major bleeding occurred postoperatively requiring several transfusions, an increase in dosage of factor VII, and administration of a heavy dose of factor VIII as a last resort. This case highlights the possibility of failure of factor replacement therapies constituting a life-threatening situation in which alternatives are few.

Spontaneous rupture of a posttraumatic aneurysm of the axillary artery-a rare cause of hemorrhagic shock in children.

Posttraumatic aneurysms of the axillary artery are extremely scarce. In pediatrics, no similar case has been described. Injuries of axillary artery are often associated with ischemic complications, whereas the bleeding risks are not well documented. We report the case of a 5-year-old boy who was admitted with a scapular pulsatile lump 2 weeks after a domestic accident. During his stay, he suddenly presented a hemorrhagic shock. The patient was immediately admitted to the operating room to undergo surgical hemostasis and was then transferred to intensive care unit to stabilize his vital functions. This case shows the possibility of spontaneous and life-threatening acute bleeding of posttraumatic aneurysms of the axillary artery.

Melena revealing a nasopharyngeal leech: a paediatric case.

Leech infestation occurs after swimming or ingestion of freshwater, especially in rural areas. Symptoms are different depending on the binding site of the leech. At the nasopharynx, it is mainly responsible for epistaxis. We report a case of an unknown pharyngeal location of a leech in a three year-old girl responsible for melena and leading to a severe anaemia.

Childhood thoracic actinomycosis: case report.

Actinomycosis is a rare bacterial infection. It has a pseudotumoral appearance when localized to the lungs or mediastinum. The diagnosis is often delayed because clinical presentation is nonspecific, bacteriologic diagnosis is difficult, and culture growth is slow. The diagnosis is mainly based upon histologic identification of actinomycotic sulfur granules. Actinomycosis is usually sensitive to penicillin G. Surgical treatment is reserved for failure of medical treatment and complications. We report a case of thoracic actinomycosis in a 13-year-old boy.
