Familial cavernous malformations of the central nervous system and retina

We studied a family in which 4 persons from three generations had multiple cavernous malformations ("angiomas") of the central nervous system (CNS) and/or retina and found accounts in the literature of sixteen other families with this condition. In these families with familial cavernous malformation of the CNS and retina, 92% of pathologically documented vascular malformations were cavernous; 50% of those subjects affected had multiple CNS and/or retinal vascular malformations and 68% (excluding probands) were symptomatic. Cutaneous vascular lesions were an inconsistant manifestation. Autosomal dominant inheritance with high penetrance was confirmed.     

Penetrating ocular injuries in young patients. Initial injuries and visual results

Penetrating injuries are a leading cause of unilateral visual loss in young patients. We reviewed the records of 197 patients aged 18 years or younger who underwent primary repair of a penetrating ocular injury at the Wilmer Ophthalmological Institute from January 1970 through December 1981. The injury was caused by sharp objects in 49% of cases, missiles in 35%, and blunt trauma in 14%. Of 159 patients with at least 6 months follow-up, 110 (69%) achieved final vision of 5/200 or better, and 77 patients (48%) achieved final visual acuity of 20/50 or better. The prognosis after a penetrating injury is strongly influenced by the nature of the injury and the extent of initial damage. Several factors were found to correlate with an unfavorable visual outcome, including: initial preoperative visual acuity of worse than 5/200, injuries due to blunt trauma, wounds involving the sclera, double penetrating injuries, dense vitreous hemorrhage, and wounds associated with an intraocular "BB" pellet.     

Implementation of a gastrostomy care bundle reduces dislodgements and length of stay

PurposePediatric gastrostomy tubes (G-tubes) are associated with considerable utilization of healthcare resources. G-tube dislodgement can result in tract disruption and abdominal sepsis. We aimed to reduce early G-tube dislodgement by 25%.MethodsAn interdisciplinary team convened to identify key drivers of G-tube dislodgement and implement initiatives to reduce this complication. A G-tube care bundle was implemented in 2018. Rates of early G-tube dislodgement (within 90 days of insertion) were tracked. 15 months of cases after bundle implementation were compared to 20 months of cases before implementation. Length of stay (LOS, balancing measure) and bundle compliance (process measure) were tracked.ResultsG-tube dislodgements decreased 47% after bundle implementation. Overall, dislodgements after G-tube insertion decreased from 43% to 19% dislodgements per tube inserted, p = 0.004. Reductions were observed for dislodgements occurring in both the inpatient (14% vs. 1.5%) and outpatient (29% vs. 18%) settings. Median LOS was reduced from 15.3 to 7.1 days following implementation, p = 0.004. Process measures demonstrated 75% or greater compliance one year after implementation.ConclusionAn interdisciplinary team using quality improvement science methodology can significantly reduce G-tube dislodgement and improve value after pediatric gastrostomy tube insertion.Type of studyLongitudinal cohort study.Level of evidenceIII.     

The relational clinical database: a possible solution to the star wars in registry systems

In summary, having data from other service areas available in a relational clinical database could resolve many of the problems existing in today's registry systems. Uniting sophisticated information systems into a centralized database system could definitely be a corporate asset in managing the bottom line.     

Presenting statistical uncertainty in trends and dose-response relations.

When one estimates the effects of a polytomous exposure, it is common practice to express all effects relative to a baseline or reference level. Certain authors have challenged this practice and proposed alternatives, which we review here. One alternative, the "floating absolute risk" method, can supply useful statistics and trend graphs, but it does not yield valid confidence intervals for relative risks. All categorical methods have further shortcomings when the exposure is continuous, however. These shortcomings can be addressed by plotting or tabulating confidence limits for points on a flexible curve fitted to the uncategorized data.     

Clinical importance of urethral pressure variations

The cause of female urethral instability is still controversial. With the help of this retrospective analysis of 1168 continuous long-term recordings of the intraurethral pressure at the maximum point of urethral pressure, the correlation between pressure variations (UPV) and simultaneous bladder instability was investigated. It could be stated that clinically important UPV (more than 15 cmH₂O) are found more often in women who suffer from signs of bladder instability (defined as low bladder compliance combined with uninhibited detrusor contractions and/or urinary leakage) than in patients without signs of unstable bladder.     

Percutaneous bunionette correction

BackgroundTreatment of tailor's bunion is largely conservative. For severe or refractory cases surgical intervention is necessary. The aim of this study is to evaluate a percutaneous technique for correcting such bunionette deformities.MethodsTwenty-one procedures were performed on 20 patients using a percutaneous technique. Patients were scored using the American Orthopaedic Foot & Ankle Society (AOFAS) Lesser Toe Metatarsophalangeal–Interphalangeal Scale.ResultsNo wound healing problems, infections, non-unions or mal-unions occurred. Functional assessments revealed very good results. Radiographic evaluation confirmed good average correction of the fourth–fifth intermetatarsal angle and metatarsophalangeal angle.ConclusionsThis percutaneous technique is a reliable and effective approach for the treatment of bunionette deformity. The results obtained were comparable to those reported using traditional open techniques, but major complications due to soft tissue damage were averted. This technique can be adapted depending on the type of deformity, and does not require internal fixation.
