Neonatal renal failure due to obstructive candidal bezoars

Acute renal failure (ARF) developed in a 7-week-old infant due to bilateral candidal bezoars (fungal balls) causing obstruction at the pelviureteric junction. The baby was born at term with an appropriate birthweight, and had been treated with broad-spectrum antibiotics for respiratory distress and septicemia during the 1st week of life. Recovery from ARF followed renal decompression with bilateral nephrostomy tube placement and parenteral administration of amphotericin B and 5-flucytosine.

Esophageal pH monitoring for gastroesophageal reflux: a United Kingdom study

Esophageal pH monitoring is the accepted standard for the investigation of gastroesophageal reflux (GER) in adults. A postal questionnaire was sent to 912 United Kingdom paediatric physicians & surgeons. Five hundred forty-seven (61%) replied, with 124 (22.7%) currently using the technique, mostly in conjunction with barium swallow and/or esophagoscopy. The use of pH monitoring to quantify GER was also accepted in principal as being the best determinant of reflux by a further 186 (34%), but as yet was unavailable in their hospitals. Pediatricians were also questioned as to their management of children with GER. The majority were treated medically with a variety of antireflux medication, with only 237 (42%) referring cases for surgery.     

The Broad Spectrum of Quality in Deceased Donor Kidneys

The quality of the deceased donor organ clearly is one of the most crucial factors in determining graft survival and function in recipients of a kidney transplant. There has been considerable effort made towards evaluating these organs culminating in an amendment to allocation policy with the introduction of the expanded criteria donor (ECD) policy.
Our study, from first solitary adult deceased donor transplant recipients from 1996 to 2002 in the National Scientific Transplant Registry database, presents a donor kidney risk grade based on significant donor characteristics, donor–recipient matches and cold ischemia time, generated directly from their risk for graft loss. We investigated the impact of our donor risk grade in a naïve cohort on short- and long-term graft survival, as well as in subgroups of the population.
The projected half-lives for overall graft survival in recipients by donor risk grade were I (10.7 years), II (10.0 years), III (7.9 years), IV (5.7 years) and V (4.5 years). This study indicates that there is great variability in the quality of deceased donor kidneys and that the assessment of risk might be enhanced by this scoring system as compared to the simple two-tiered system of the current ECD classification.     

Safety of ciprofloxacin in children: Worldwide clinical experience based on compassionate use. Emphasis on joint evaluation

Summary Six hundred and thirty four adolescents and children aged three days to 17 years treated with ciprofloxacin on a compassionate basis were analysed for drug safety. 62% of the ciprofloxacin courses were given to patients with respiratory tract infection, primarily those with acute pulmonary exacerbation of cystic fibrosis. The mean daily oral dose was 25.2 mg/kg body weight. The duration of treatment ranged from one to 880 days (mean 22.8 days). Because of the arthropathogenic potential of quinolones in juvenile animals special emphasis was placed on the evaluation of musculoskeletal adverse events. Arthralgia considered by the treating physicians to be related to ciprofloxacin was reported in eight children, all of whom were females. Arthralgia resolved in all children. Some of these children were given subsequent courses of ciprofloxacin with no complaints of arthralgia. Overall, the safety profile of ciprofloxacin in children is not substantially different from that of adults.

Verträglichkeit von Ciprofloxacin bei Kindern unter besonderer Beachtung der Gelenke. Auswertung weltweit dokumentierter Problemfälle

Zusammenfassung Die Verträglichkeit des Ciprofloxacin nach Anwendung bei 634 Jugendlichen und Kindern im Alter von drei Tagen bis 17 Jahren wurde analysiert. 62% der Behandlungen mit Ciprofloxacin erhielten Patienten mit Atemwegsinfektionen, insbesondere mit akuter pulmonaler Exazerbation der Mukoviszidose. Der Mittelwert der oralen Tagesdosis war 25,2 mg/kg Körpergewicht. Die Therapiedauer variierte zwischen 1 und 880 Tagen (Mittelwert 22,8 Tage). Wegen der gelenkknorpelschädigenden Wirkung der Chinolone bei juvenilen Versuchstieren wurde besondere Aufmerksamkeit der Beurteilung der mit Gelenken verbundenen Nebenerscheinungen gewidmet. Arthralgie, die von den behandelnden Ärzten als Folge der Ciprofloxacin-Behandlung beurteilt wurde, ist bei acht Kindern berichtet worden. Alle waren weiblich. Die Arthralgie verschwand bei allen Kindern. Einige dieser Kinder erhielten nachträgliche Behandlungen mit Ciprofloxacin ohne Auftreten arthralgischer Beschwerden. Generell unterschied sich das Verträglichkeitsprofil bei Kindern nicht wesentlich von dem der Erwachsenen.

     

The intubating laryngeal mask airway: an initial assessment of performance

A new prototype of the laryngeal mask airway (LMA), the intubating laryngeal mask airway (ILMA), was used to facilitate tracheal intubation in 100 fasted patients presenting for elective surgery. Alignment of the ILMA with the larynx was assessed fibreoptically before intubation without the investigator performing the intubation being aware of the view score. Ease of intubation correlated with the view obtained and with the degree of manipulation of the ILMA needed to achieve tracheal intubation. Intubation was successful in 93 patients. Of the seven intubation failures, five occurred in the first 20 patients. Conventional connection to the breathing system and ventilation of the lungs of the patients were possible throughout the intubation procedure.      

Treatment of dual diagnosis patients: A relapse prevention group approach

The authors describe the successful use of an adjunctive group psychotherapy for substance-abusing patients with major psychiatric disorders (bipolar, schizophrenia, schizoaffective, psychotic depression, and atypical psychosis). The group utilizes a psychoeducational approach that focuses on substance abuse causes and consequences, principles of recovery, and relapse prevention strategies. Eight patients with prolonged histories of abuse of cocaine, alcohol, marijuana, or other drugs were enrolled in this weekly group treatment at a community mental health center drug treatment program, while continuing in treatment with their current case manager or primary therapist. Six of the eight patients achieved periods of stable abstinence, documented by self-report, urine toxicology screens, continued group attendance, and improved social functioning. Case examples are utilized to illustrate the group process.

An adenovirus type 5 (AdV5) vector encoding an envelope domain III-based tetravalent antigen elicits immune responses against all four dengue viruses in the presence of prior AdV5 immunity

Dengue is a mosquito-borne viral disease caused by four antigenically distinct serotypes of dengue viruses (DENVs). This disease, which is prevalent in over a hundred tropical and sub-tropical countries of the world, represents a significant global public health problem. A tetravalent dengue vaccine capable of protecting against all four DENV serotypes has been elusive so far. Current efforts are focused on producing a tetravalent vaccine by mixing four monovalent vaccine components. In this work, we have utilized a discrete carboxy-terminal region of the major DENV envelope (E) protein, known as domain III (EDIII), which mediates virus entry into target cells and contains multiple serotype-specific neutralizing epitopes, to create a chimeric tetravalent antigen. This antigen derived by in-frame fusion of the EDIII-encoding sequences of the four DENV serotypes was expressed using a replication-defective recombinant human adenovirus type 5 (rAdV5) vaccine vector. This rAdV5 vector induced cell-mediated immune responses and virus-neutralizing antibodies specific to each of the four DENVs in mice. Interestingly, anti-AdV5 antibodies did not suppress the induction of DENV-specific neutralizing antibodies. We observed that anti-AdV5 antibodies in the sera of immunized mice could promote uptake of a rAdV5-derived reporter vector into U937 cells, suggesting that pre-existing immunity to AdV5 may in fact facilitate the uptake of rAdV5 vectored vaccines into antigen presenting cells. This work presents an alternative approach to developing a single component tetravalent vaccine that bypasses the complexities inherent in the currently adopted four-in-one physical mixture approach.     

Optimizing Cancer Radiotherapy with 2-Deoxy-D-Glucose Dose Escalation Studies in Patients with Glioblastoma Multiforme

Background and Purpose:  

Higher rates of glucose utilization and glycolysis generally correlate with poor prognosis in several types of malignant tumors. Own earlier studies on model systems demonstrated that the nonmetabolizable glucose analog 2-deoxy-D-glucose (2-DG) could enhance the efficacy of radiotherapy in a dose-dependent manner by selectively sensitizing cancer cells while protecting normal cells. Phase I/II clinical trials indicated that the combination of 2-DG, at an oral dose of 200 mg/kg body weight (BW), with large fractions of γ-radiation was well tolerated in cerebral glioma patients. Since higher 2-DG doses are expected to improve the therapeutic gain, present studies were undertaken to examine the tolerance and safety of escalating 2-DG dose during combined treatment (2-DG + radiotherapy) in glioblastoma multiforme patients.
