Feasibility of awake craniotomy in the pediatric population.

Background: Awake craniotomy with direct cortical stimulation and mapping is the gold standard for resection of lesions near eloquent brain areas, as it can maximize the extent of resection while minimizing the risk of neurological damage. In contrast to the adult population, only small series of awake craniotomies have been reported in children.

Aims: The aim of our study is to establish the feasibility of awake craniotomy in the pediatric population.

Prophylactic HIPEC in pT4 Colon Tumors: Proactive Approach or Overtreatment?

Background: The peritoneum is the second most common site for metastasis in patients with colorectal cancer. Various factors have been studied to identify patients at risk of developing peritoneal carcinomatosis (PC), including T4 tumors. The objectives were to assess the incidence of synchronous and metachronous PC, explore potential risk factors for developing PC as the only site of metastasis, and identify which patients might be candidates for prophylactic hyperthermic intraperitoneal chemotherapy (HIPEC).

Ultrasound-guided maxillary nerve block: an anatomical study using the suprazygomatic approach.

Purpose: Although a maxillary nerve (MN) block reportedly provides satisfactory analgesia for midface surgery and chronic maxillofacial pain syndromes, a safe and reliable MN block technique has not been reported. The goal of this anatomical study was to quantify the various angles and depth of the block needle, as well as to evaluate the impact of volume on the extent of injectate spread that might influence anesthetic coverage and block-related complications.

Methods: Following an ultrasound-guided suprazygomatic MN block with dye injection, a dissection was performed in the pterygopalatine fossa (PPF) of four lightly embalmed cadaveric specimens.

Bilateral suprazygomatic maxillary nerve blocks vs. infraorbital and palatine nerve blocks in cleft lip and palate repair: A double-blind, randomised study.

Background: Cleft defects are common craniofacial malformations which require early surgical repair. These patients are at high risk of postoperative airway obstruction and respiratory failure. Cleft surgery may require high doses of opioids which may contribute to these complications.

Monopoly Airplane Lands in Esophagus Leading to Difficult Extraction: A Case Report on Anesthesia and Surgical Considerations.

A 2-year-old child presented with an airplane game piece from the board game Monopoly lodged in her esophagus. The airplane's wings, engines, and winglets acted like fish hooks that entered the esophageal mucosa easily but were difficult to extract. Chest radiographs were used to estimate the airplane wingspan dimensions, and a Foley catheter was used to dilate the esophagus to allow foreign body extraction via rigid esophagoscopy with optical forceps.

Role of Postoperative Antimicrobials in Cleft Palate Surgery: Prospective, Double-Blind, Randomized, Placebo-Controlled Clinical Study in India.

Background: The purpose of this study was to determine whether administration of postoperative antibiotics affects the incidence of complications after primary cleft palate repair in a developing area.

Methods: This study was a prospective, double-blind, randomized, placebo-controlled trial composed of 518 consecutive patients who underwent primary cleft palate repair at a single institution. Patients were aged 1 to 43 years at the time of surgery (median, 9 years).

Incidence and timing of hypotension after transcervical carotid artery stenting: correlation with postoperative complications.

Objectives: To assess the incidence and timing of hypotension after carotid artery stenting (CAS) and its correlation with postoperative complications.

Background: CAS-associated postoperative hypotension has been linked to surgical morbidity and mortality, especially to stroke and cardiac complications.

Methods: Ninety-seven consecutive patients undergoing transcervical CAS were monitored for at least 12 hr after operation.

Serological protection induced by Haemophilus influenzae Type B conjugate vaccine in Mexican children: is a booster dose of the vaccine needed?

We determined the seroprevalence of protective antibodies against Hib in Mexican children under the age of five using a standardized enzyme-linked immunosorbent assay. Hib antibodies (≥ 0.15 μg/ml) were present in 95.

[Antibiotic use in Mexico: review of problems and policies].

The inappropriate use of antibiotics signifies a risk for individual health and a waste of health resources. It triggers the development of antibiotic resistance, which increases expenditures and mortality related to infectious disease, and is hence considered a serious public health problem. The World Health Organization has thus recommended a series of strategies to be included within national pharmaceutical policies.

Antibiotic resistance in Streptococcus pneumoniae in six Latin American countries: 1993-1999 surveillance.

The impact of invasive pneumococcal invasive disease is increased by the emergence of antibiotic resistance. We report regional and temporal variations in antibiotic resistance for 4,105 invasive Streptococcus pneumoniae isolates collected from Latin American children <5 years, between 1993 and 1999. Reduced susceptibility to penicillin was detected in 1,182 isolates (28.

Outbreak of infection with extended-spectrum beta-lactamase-producing Klebsiella pneumoniae in a Mexican hospital.

Thirty-one strains of Klebsiella pneumoniae (including 10 duplicates) from 21 septicemic pediatric patients (age, <2 months) were studied during a 4-month period (June to October 1996) in which the fatality rate was 62% (13 of 21). These isolates identified by the API 20E system yielded the same biotype. Pulsed-field gel electrophoresis experiments revealed the same clone in 31 strains.

[Impact of Streptococcus pneumoniae on pneumonia in Latin American children. SIREVA-Vigía Group].

Community-acquired pneumonia is one of the leading causes of infant morbidity and mortality. Studies conducted in developing countries indicate that the most serious symptoms of pneumonia are associated with bacterial causes, mainly Streptococcus pneumoniae, followed by Haemophilus influenzae type b. Managing those infections in children under two years of age is hindered by the lack of appropriate vaccines and by the decreased susceptibility of S.

Susceptibility to new beta-lactams of enterobacterial extended-spectrum beta-lactamase (ESBL) producers and penicillin-resistant Streptococcus pneumoniae in Mexico.

The activities of several beta-lactam antimicrobial agents, aminoglycosides and ciprofloxacin, were determined against 62 clinical isolates of enterobacteria resistant to oxyimino cephalosporins (extended-spectrum beta-lactamase producers), collected during 1991 to 1993, and 16 penicillin-resistant invasive isolates of Streptococcus pneumoniae collected during 1994-1996. The numbers and percentages of susceptible enterobacterial strains to tested antibiotics were: imipenem 60 (97%), ciprofloxacin 57 (92%), cefepime 56 (90%), cefpirome 34 (55%), aztreonam 13 (21%), cefotaxime 7 (11%), ceftazidime 0 (0%), amikacin 11 (18%) and gentamicin 16 (26%). Despite the fact that these strains had never been exposed previously to cefepime or cefpirome, the susceptibility was 90% and 55%, respectively.

Treatment of presumed bacterial pneumonia in ambulatory children.

In a prospective, randomized, open study, a combination of trimethoprim and rifampin (TMP/R) 20 mg/kg/day was compared with ampicillin (AMP) 150 mg/kg/day, both given orally twice daily for 10 days, for the treatment of 60 children who had mild community-acquired pneumonia. The control group comprised 112 healthy children. The overall duration of the disease was 8.

Serogroup specificity and antimicrobial susceptibilities of Neisseria gonorrhoeae isolated in Mexico City.

The serogroup pattern of 87 clinical isolates of Neisseria gonorrhoeae was determined by monoclonal coagglutination and the in-vitro activity of seven antimicrobial agents against the same strains was tested by an agar dilution method. The frequency of resistance to spectinomycin, ampicillin, penicillin, erythromycin, chloramphenicol and tetracycline was 14.9%, 33.

Results of treatment of uncomplicated urogenital gonorrhoea with enoxacin compared with ceftriaxone.

The increasing incidence of penicillinase producing Neissreria gonorrhoeae (PPNG) and chromosomally-mediated resistant N. gonorrhoeae (CMRNG) has generated a need for therapy other than penicillin. PPNG constitutes about 30% of the circulating strains of gonococci in the high risk population in Mexico City.
