Early vs late surgical treatment of radial instability of the thumb metacarpophalangeal joint. A retrospective cohort study.

There is no clear evidence in the literature whether treating thumb radial collateral ligament (RCL) injury in the acute phase improves outcome. The purpose of the present study was to compare the clinical and radiological results of RCL repair in acute and chronic settings. Fourteen patients were included. Clinical range of motion (ROM) of the thumb, Kapandji score and radiological parameters were compared pre- and post-operatively to the contralateral uninjured thumb (control group) to evaluate the results of the surgical technique. Patients were then divided into two groups according to early versus late repair and outcomes were compared between the two groups and the control group. Preoperatively, mean spontaneous angle between first metacarpal (M1) and proximal phalanx (P1) (spontaneous M1P1 angle), ulnar stress M1P1 angle, ROM and Kapandji score differed significantly between injured and uninjured sides. Postoperatively these parameters for the injured side improved, reaching values similar to those on the uninjured side, especially with acute phase treatment; late treatment also tended to provide clinical improvement in ROM, Kapandji score and ulnar stress angle, but with significant improvement only for spontaneous deviation of the thumb. This study showed the late and immediate repair of the RCL of the thumb both gave good results, with slightly better outcome with acute phase repair. LEVEL OF EVIDENCE: Therapeutic, Level III.

Understanding the foot's functional anatomy in physiological and pathological conditions: the calcaneopedal unit concept.

BACKGROUND: A thorough review of the available orthopaedic literature shows significant controversies, inconsistencies and sparse data regarding the terminology used to describe foot deformities. This lack of consensus on terminology creates confusion in professional discussions of foot anatomy, pathoanatomy and treatment of deformities. The controversies apply to joint movements as well as static relationships between the bones. DESCRIPTION: The calcaneopedal unit (CPU) is a specific anatomical and physiological entity, represented by the entire foot excepted the talus. The calcaneus, midfoot and forefoot are solidly bound by three strong ligaments that create a unit that articulates with the talus. The movement of the CPU is complex, as it rotates under the talus, around the axis of Henke that coincides with the talo-calcaneal ligament of Farabeuf.This calcaneopedal unit is deformable. It is compared with a twisted plate, able to adapt to many physiological situations in standing position, in order to acheive a plantigrade position.Moreover, the calcaneopedal unit and the talo-tibiofibular complex are interdependent; rotation of the latter produces morphologic modifications inside the former and vice versa. PURPOSE: This paper is a review article of this concept and of its physiopathological applications.

Positional disappearance of motor evoked potentials is much more likely to occur in non-idiopathic scoliosis.

PURPOSE: This study evaluates intraoperative disappearance of motor waveforms related to patient positioning in neurologically asymptomatic patients with spinal deformity. METHODS: This is a retrospective review of 190 neurologically asymptomatic patients aged seven to 17 years planned for posterior instrumentation under neuromonitoring. There were 159 patients with adolescent idiopathic scoliosis and 31 patients with secondary scoliosis. Patients underwent surgery with transcranial electric stimulation motor evoked potentials (TES-MEPs). In case of abnormal findings, surgery was temporarily discontinued and necessary measures undertaken. In case of permanent signal disappearance surgery was definitively discontinued. RESULTS: Six patients showed permanent loss of signal during early stages of surgery. These patients had a mean major curve of 64° Cobb angle and a mean thoracic kyphosis (D2 to D12) of 72°. The 184 remaining patients had a mean major curve of 50° Cobb angle and a thoracic kyphosis of 35°. A retrospective descriptive review of the patients' radiographs shows hyperkyphosis to be the common ground between the six secondary scoliosis cases. Gradual preoperative traction maintained during the surgery applied in two of these patients taken back to surgery six months later was associated with maintenance of TES-MEP signals throughout the surgery. CONCLUSION: This study shows that positional permanent loss of neuromonitoring signals is more likely to occur in patients with secondary scoliosis and hyperkyphosis shown to have sharper spine deformity and suspected to have a more vulnerable spinal cord. Gradual skeletal traction performed in two of these patients and maintained during surgery showed promising results. LEVEL OF EVIDENCE: IV.

Selecting the lowest instrumented vertebra in adolescent idiopathic scoliosis: Comparison of the Lenke, Suk, and Dubousset criteria.

BACKGROUND: Selection of the lowest instrumented vertebra (LIV) in patients undergoing selective fusion for Lenke type 1 or 2 adolescent idiopathic scoliosis (AIS) varies widely across centres around the world. HYPOTHESIS: Lenke, Suk, and Dubousset criteria show moderate agreement for LIV selection. METHODS: Sixty-eight patients with Lenke type 1 or 2 AIS managed by selective posterior fusion and followed-up for at least 2 years were included in a retrospective observational study. Agreement among Lenke, Suk, and Dubousset criteria for LIV selection was assessed. For surgery, the LIV was selected based on Dubousset criteria. Retrospectively, in each patient, the LIV selected by the Lenke and Suk criteria sets was identified on the preoperative images. The patients were then divided into two groups based on whether the Dubousset LIV was identical versus more distal than the LIV identified retrospectively by the Lenke or Suk criteria. The primary evaluation criterion was coronal balance. RESULTS: The LIVs selected by the Lenke, Suk, and Dubousset criteria were identical in 57% of cases. The LIV selected by the Dubousset criteria were identical to that selected by the Lenke or Suk criteria in 70% of patients. No significant between-group differences were found for any of the evaluation criteria assessed preoperatively, postoperatively, or at last follow-up. DISCUSSION: Agreement among the Lenke, Suk, and Dubousset criteria was moderate, confirming the working hypothesis. No coronal malalignment developed in the patients whose actual LIV was distal to the LIV selected by the Lenke or Suk criteria, supporting the validity of Dubousset criteria for LIV selection. When selecting the LIV, all three criteria sets should be assessed. The LIV is the vertebra selected by all three if they agree or by the Dubousset criteria if they do not. LEVEL OF EVIDENCE: IV, retrospective cohort study.

Sclerotherapy using Surgiflo and alcohol: a new alternative for the treatment of aneurysmal bone cysts.

PURPOSE: This study aims to review the results of sclerotherapy using Surgiflo in addition to alcohol in primary aneurysmal bone cysts (ABC). METHODS: A total of 16 consecutive patients with histologically confirmed diagnosis of primary ABC were treated by percutaneous Surgiflo and alcohol injection at our institution. Clinical follow-up included the assessment of pain, swelling, limping and functional impairment. Radiological parameters included tumour volume, physis-cyst distance, thickness of cyst cortex, and presence of intracystic septations. Mean follow-up was 35,6 months (24-71 months). Treatment was considered successful when the cyst volume decreased by a minimum of 10%, the bone cortex became thicker, and the distance to physis increased. RESULTS: Mean age at presentation was 9.5 years (5.16-13.84 years). All ABC's were primary and all patients underwent a single Surgiflo and alcohol session except for two (12.5%) who required a second session. All patients had a good clinical result at final follow-up. Satisfactory cyst healing was achieved in 11 cases according to radiological parameters. Tumour volume decreased from a mean of 122 cm3 (111 to 133) before injection to 86 cm3 (76 to 96) at last follow-up (p < 0.01). Physis-cyst distance increased from a mean of 1 cm (0.1 to 2) to 2.1 cm (0.5 to 4) at last follow-up (p < 0.01). Cortical thickness improved from 1 mm (0.5 to 1.5) to 2 mm (1 to 3.5) at last follow-up (p < 0.01).There were no treatment related complications. Surgery was performed in one patient having a C3 vertebra ABC after developing quadriparesis due to tumour progression. CONCLUSION: Sclerotherapy using Surgiflo and alcohol may be used as an efficient, safe and minimally invasive alternative for the treatment of primary ABCs.

Women's experiences of maternity care: satisfaction or passivity?

This study is a first attempt to describe Lebanese women's responses to the medical management of their pregnancy and delivery. A qualitative approach in data collection and analysis was adopted to gain an in-depth view of women's perceptions. Women of any parity undergoing a normal vaginal delivery during the three months preceding the interview were interviewed in different areas in Lebanon: one urban, one semi-rural and two remote rural. Childbirth for all the women interviewed was managed within the medical system. Findings show that women accord total trust to their physicians, and very rarely question the usefulness of many routinely applied procedures, even those which the literature shows are unnecessary. When probed, women report that many aspects of the technical care are intimidating and that they experience discomfort with these procedures. Women are more vocal about patient-provider communication and value good interaction with their provider. The extent of passivity and feelings of discontent women have varies according to their social class and the amount of psychosocial support they receive throughout the process of childbirth.

A population-based study of age and gender differences in patterns of health-related behaviors.

PURPOSE: Most research on preventive health behaviors has focused on individual rather than groups of behaviors. This study examined interrelationships among multiple preventive health behaviors in different age and gender groups. METHODS: From 1990 to 1992, Maryland residents were surveyed by telephone through the Behavioral Risk Factor Surveillance System. The study sample of 4455 was divided into 8 groups based on age (18-24, 25-39, 40-54, and 55+) and gender. Correlation and oblique rotated factor analyses were used to examine patterns of 8 to 11 preventive health behaviors in each age-gender group. RESULTS: Medical checkup and cholesterol test formed one behavioral cluster in the four male age groups. Breast and cervical cancer screening (mammogram, clinical breast examination [CBE], and Pap Smear) did not form one cluster until age 55 or older; Pap smear, CBE formed one cluster for women of all ages. Risk-taking behaviors were only prominent in the youngest age group: Seatbelt non-use, smoking, and drinking formed one cluster in younger males, and drinking and driving after drinking clustered in younger females. CONCLUSION: Screening and risk-taking behaviors form distinct groups, and behavioral patterns differ by age and gender. Public health programs should consider multi-behavioral approaches, and be sensitive to the gender and age of the target population.

Planning for the sustainability of community-based health programs: conceptual frameworks and future directions for research, practice and policy.

Attention to the sustainability of health intervention programs both in the US and abroad is increasing, but little consensus exists on the conceptual and operational definitions of sustainability. Moreover, an empirical knowledge base about the determinants of sustainability is still at an early stage. Planning for sustainability requires, first, a clear understanding of the concept of sustainability and operational indicators that may be used in monitoring sustainability over time. Important categories of indicators include: (1) maintenance of health benefits achieved through an initial program, (2) level of institutionalization of a program within an organization and (3) measures of capacity building in the recipient community. Second, planning for sustainability requires the use of programmatic approaches and strategies that favor long-term program maintenance. We suggest that the potential influences on sustainability may derive from three major groups of factors: (1) project design and implementation factors, (2) factors within the organizational setting, and (3) factors in the broader community environment. Future efforts to develop sustainable health intervention programs in communities can build on the concepts and strategies proposed here.

PIP: Many community-based health programs implemented in developing countries around the world are discontinued soon after initial funding ends. Attention to the sustainability of health intervention programs in the US and abroad has increased in recent years as policymakers and funders become ever more concerned with allocating scarce resources effectively and efficiently. There is, however, little consensus upon the conceptual and operational definitions of sustainability. Planning for program sustainability requires a clear understanding of the concept of sustainability and operational indicators which can be used to monitor sustainability over time, as well as the use of programmatic approaches and strategies which favor long-term program maintenance. Potential influences upon sustainability may derive from the following factors: project design and implementation factors, factors in the organizational setting, and factors in the broader community environment.

Linking implementation to outcomes: evaluation of a community-based breast and cervical cancer screening program.

UNLABELLED: An implementation analysis of the first eighteen months of the Maryland Breast and Cervical Cancer Program examined the variability among participating local agencies in the extent of screening services delivered; local program implementation processes; and the relationships between extent of screening and the local level processes. The study used: 1) a mail and telephone survey of local health departments (LHD, N = 24) and 2) state program surveillance data, with correlational methods. OUTCOMES MEASURED: 1) "Penetration," the proportion of the target population screened; and 2) "Efficiency," the number of women screened per program staff member. Categories of implementation variables were: 1) Environment, 2) Staffing, 3) Collaboration with community organizations, 4) Outreach, 5) Provider variables, 6) Relationships with State and LHDs, 7) Organizational variables, and 8) Service delivery. Results showed wide local variability in screening levels. Availability of local resources; provider involvement; success of community linkages; and local health department readiness showed relationships with the extent of local screening. Studying implementation is needed to improve the effectiveness and efficiency of community-based programs.

Community-wide outbreak of group G streptococcal pharyngitis.

Although several outbreaks of group G beta-hemolytic streptococcal (GGBHS) pharyngitis have been described, doubt still remains regarding the etiologic role of GGBHS in acute pharyngitis beyond a limited number of situations. In the winter/spring of 1986/87, throat cultures were obtained from 222 consecutive children seen at a private pediatric office with acute pharyngitis and group A beta-hemolytic streptococci (GABHS) were recovered from 91 children (41%) and GGBHS from 56 children (25%). One patient had both GABHS and GGBHS isolated. This isolation rate of GGBHS was dramatically greater than in previous and subsequent years, and 67% of the GGBHS isolates occurred during an 8-week period. Results of DNA fingerprinting of the 57 isolates of GGBHS demonstrated that 43 (75%) appeared to be the same strain. The patients with GGBHS were comparable to those with GABHS with respect to clinical findings, antistreptolysin-O titer response, and clinical response to antibiotic therapy. However, patients with GGBHS were significantly older (P less than .05). This is the first well-documented, community-wide outbreak of GGBHS pharyngitis and the first respiratory outbreak of GGBHS pharyngitis in a pediatric population. GGBHS may be a more important cause of acute, treatable pharyngitis than had been previously recognized.

Toxic shock syndrome caused by a strain of Staphylococcus aureus that produces enterotoxin C but not toxic shock syndrome toxin-1.

An 8-month-old infant presented with pneumonia and pleural effusion associated with clinical manifestation of toxic shock syndrome. A Staphylococcus aureus strain isolated from the pleural fluid produced enterotoxin C, but not toxic shock syndrome toxin-1 or other enterotoxins. Acute and convalescent sera showed an antibody rise to enterotoxin C but not to toxic shock syndrome toxin-1. These findings support the possibility that enterotoxin C was the primary toxin associated with this infant's illness.

Acute thrombocytopenic purpura and poststreptococcal acute glomerulonephritis in a child.

The occurrence of acute idiopathic thrombocytopenia purpura in association with poststreptococcal glomerulonephritis in a 5 1/2-year-old boy is described. This association has been reported only in two cases in the literature. We are reporting the first biopsy-proven confirmation of this association.
