Treves' field congenital hernias in children: an unsuspected rare cause of acute small bowel obstruction.

The Treves' field congenital hernias (TFCH) are an unusual cause of bowel obstruction that may result in irreversible damage of the small bowel or a fatal outcome, unless treated timely and properly. We analyzed retrospectively the medical records of four patients who underwent surgery for TFCHs over a period of 9 years. The types of TFCHs, only diagnosed at surgery, were identified as transmesenteric through a defect in Treves' field in three patients, and as hernia into Treves' field pouch in one patient. Patients had non-specific clinical manifestations, and imaging findings demonstrated only small bowel obstruction. Delay in accurate preoperative diagnosis, and especially patient-related delay, led to a primary enterectomy-anastomosis for necrotic small bowel in the patients with transmesenteric hernias. One infant with necrotic bowel died postoperatively. It may be difficult to diagnose TFCHs in children preoperatively. Misdiagnosis of bowel obstruction caused by this type of internal hernia might lead to small bowel necrosis or death. The risk of this complication seems to be more influenced by pre-hospital delay. Awareness of the severe consequences of delay in diagnosis, high clinical suspicion, early recognition, and proper surgical intervention are essential in the successful management of TFCHs.

Wound infections after minor limb lacerations: risk factors and the role of antimicrobial agents.

BACKGROUND: The requirement for antimicrobial agents in patients with minor limb lacerations was prospectively studied. METHODS: The development of wound infections in patients with minor limb lacerations who received amoxicillin plus clavulanate acid treatment (group A, 52 patients) was studied and compared with patients who did not (group B, 48 patients). RESULTS: Wound infection occurred in 6 (11.5%) and 10 (21%) patients in groups A and B, respectively (p>0.10). Statistically significant risk factors for the development of infection were diabetes mellitus (odds ratio [OR], 15.8; p<0.001), lower limb lacerations (OR, 33.5; p<0.001), lacerations caused by compressive forces (OR, 21.6; p = 0.007), laceration length from 5 to 8 cm (OR, 7.04; p = 0.001), ragged laceration edge (OR, 2.55; p = 0.049), and skin tension (OR, 2.00; p = 0.006). CONCLUSION: The use of antimicrobial agents in minor limb injuries was not associated with a significant reduction of infection rate. Routine antimicrobial treatment is discouraged.

Hickman-Broviac catheter-related infections in children with malignancies.

Infectious complications are frequently encountered following Hickman-Broviac (H-B) catheter insertion. The medical records of 164 children with malignancies who underwent H-B catheter insertion from March 1, 1988 to December 31, 1997 were reviewed retrospectively. During a 35,697 catheter-day period, 77 catheter-related infections occurred, including 50 catheter-insertion-site infections and 27 bloodstream infections. The risk for the development of catheter-related infections was 2.15 per 1000 catheter-days (1.4 and 0.75 per 1000 catheter-days for catheter-insertion-site and bloodstream infections, respectively). In 17 (63%) of 27 episodes of bloodstream infections, antimicrobial treatment controlled the infection without catheter removal. A previous catheter-insertion-site infection caused by Staphylococcus epidermidis (p=0.01), the occurrence of mechanical catheter complications (p=0.007), and a normal coagulation status of the host (p=0.03) were significantly associated with the development of catheter-related bloodstream infections. H-B catheters remain important in pediatric oncology. Due to the significant morbidity associated with the development of catheter-related bloodstream infections, risk factors found to increase the incidence rate of such infections must be identified and properly managed.

Risk factors for childhood burn injuries: a case-control study from Greece.

During a 12-month period 239 children who presented with a burn injury at the Emergency Department of a teaching children's hospital in Athens, with city-wide coverage, and 239 gender- and age-matched controls with minor non-injury ailments were interviewed. The questionnaire covered sociodemographic characteristics of the children and their families, information allowing the construction of a burn avoidance index in their homes and items from the Achenback scale that were synthesized into a child activity score. The data were analyzed through conditional logistic regression. In general, socio-demographic variables were not of overwhelming importance, although some of the findings indicate that supervision lapses and barefoot walking of gypsy children increase the risk of burn injuries. The kitchen in an inherently high risk place for injuries and the powerful inverse association of the burn avoidance index with burn injury risk points towards steps that could be easily taken and impart substantial protection. There was no evidence in this study of burn injury proneness or that hyperactivity of the child increased the risk of burn injury; indeed, the results point in the opposite direction. Our results strongly support the view that childhood burn injuries are largely environmentally conditioned and, accordingly, easily preventable.

Hazards of baby walkers in a European context.

OBJECTIVES: To identify conditions related to baby walker injuries in a Greek population. DESIGN: Analysis of all baby walker related injuries recorded during a 12 month period by the childhood injury surveillance system established in one of the two teaching hospitals for children serving the population of Athens. SETTING: Emergency clinics of A Kyriakou Children's Hospital in Athens, Greece. SUBJECTS: 49 babies with baby walker related injuries brought to the emergency clinics during the period May 1994 to April 1995. RESULTS: The incidence of these injuries was 16 per thousand person years of users, or 3.5 per thousand babies per year. More boys than girls were brought to the hospital for these injuries and the incidence density was highest during the ninth and 10th month of age. Falls from heights, particularly stairs, were the most frequent cause of baby walker related injuries, especially among younger babies. The majority of these injuries were of minor severity, but three babies had bone fractures and one had a second degree facial burn. Six babies required hospitalization and for seven others, a follow up visit was needed. The higher proportion of hospitalization among girls than boys raises the possibility that boys with minor injuries are more frequently brought to the hospital. CONCLUSIONS: Baby walkers impart a significant risk of injury from a consumer product that provides no clearly identifiable benefit. As most baby walker injuries happen on stairs, modifications in product design are required to reduce these injuries. Moreover, parents should be forcefully advised of the risks and predisposing conditions, if baby walkers are to be used at all.

[Cryosurgery in vasomotor rhinitis]. / La criochirurgia nelle riniti vasomotorie.

Experience with cryotherapy of vasomotor rhinitis is reported. This proved effective with respect to occlusive and seromucous secretory components. The concomitant vasomotor phenomena such as cephalea and oviduct obstructions received some benefit. The probable mechanism of cryotherapeutic treatment and how to use the various probes are also illustrated.

Volvulus of the sigmoid colon.

Sigmoid volvulus in children is quite rare and may occur in acute fulminating form requiring early diagnosis and surgery. In this case, bowel continuity after resection of the necrotic sigmoid was reestablished in a two-stage operation.
