Theoretical interrelationships among immunologic and hematologic sequelae of thermal injury.

A hypothesis of possible interrelationships among immunologic and hematologic sequelae of thermal injury is presented. It is postulated that there are definable pathways involving series of abnormalities with multiple interconnections among these pathways. The initiating step of each pathway should be amenable to blockade. Such blockade would theoretically circumvent the occurrence of the abnormalities or lessen their severity and thereby preserve host resistance.

Sequelae of acute myocardial infarction regarding cardiac structure and function and their prognostic significance as assessed by magnetic resonance imaging.

AIMS: Because of its high spatial resolution and tissue contrast, magnetic resonance imaging (MRI) was used to assess cardiac structure and function in a large population of patients with acute myocardial infarction (AMI). METHODS AND RESULTS: One hundred and ten patients were studied by MRI 6.1 +/- 2.2 days after AMI. Infarct size (IS), persistent microvascular obstruction (PMO), left and right ventricular (LV/RV) volumes, and functions were measured. The same MRI measurements were repeated in 89 patients after a mean follow-up period of 225 +/- 92 days. IS was 11.9 +/- 7.3% of total LV muscle mass. PMO was detected in 51/110 (46.4%) patients and comprised 15.6 +/- 8.5% of IS and 2.8 +/- 2.3% of LV muscle mass. Papillary muscle infarct was seen in 26%, RV infarction in 16%, pericarditis in 40%, and pericardial effusion in 66% of the patients. During follow-up, there were 16 major adverse cardiac events (MACE) including seven deaths. IS, PMO, and amount of transmural infarction were predictive for LV adverse remodelling defined as > 20% increase in LV end-diastolic volume. Multivariable analysis revealed LV end-diastolic volume, LV ejection fraction, and PMO as significant predictors for the occurrence of MACE. CONCLUSION: MRI is a highly sensitive and reliable tool to detect morphologic and functional sequelae of AMI providing baseline MRI parameters with relevant predictive power for LV adverse remodelling and occurrence of MACE.

Physiological aspects and clinical sequelae of energy deficiency and hypoestrogenism in exercising women.

Amenorrhoea associated with reduced caloric intake and strenuous exercise leads to hypoestrogenism and is associated with clinical manifestations that include disordered eating, stress fractures, osteoporosis, and, as recently reported, a potential increase in the risk of premature cardiovascular disease. Disordered eating, menstrual irregularities and bone loss comprise the clinical condition known as the 'female athlete triad'. The aetiology of the triad is linked to a high prevalence of disordered eating and cognitive restraint. This results in inadequate caloric intake for high exercise energy expenditures that leads to energy deficiency. This in turn stimulates compensatory mechanisms, such as weight loss or energy conservation, subsequently causing a central suppression of reproductive function and concomitant hypoestrogenism. Because the aetiology of menstrual disturbances and the female athlete triad is causally linked to energy deficiency, there is no justification for fears that exercise itself is unhealthy for women. However, improved detection, monitoring, and treatment of all components of the triad in exercising women should be emphasized. This paper critically reviews the physiological aspects and clinical sequelae of energy deficiency and hypoestrogenism associated with the female athlete triad in exercising women.

Sequelae of Venezuelan equine encephalitis in humans: a four year follow-up.

The purpose of this study was the identification of possible sequelae of the infection of human individuals with Virus of Venezuelan Equine Encephalitis (VEE). Special emphasis was laid on exploring neurological, psychological and behavioural aspects and particularly on the search for a possible association of the disease with epileptic phenomena, brain damage and/or mental deficiency. A four-year period of observation was conducted on a sample of children from El Carmelo (Colombia) where an epidemic of VEE took place in 1967. A group of seven children who presented the encephalitic type of the illness and were hospitalized with symptoms of CNS involvement and a confirmed diagnosis of VEE constituted the index group. This group was compared with four control groups of children with matched demographic characteristics but separated according to whether they were ill at the time of the epidemic and whether they presented serological evidence of having been infected with VEE Virus. Evaluations were conducted at three points in time during the follow-up period and they included the following procedures: (1) Survey on personal background and behaviour (through a standard questionnaire dealing with all areas of functioning); (2) Complete paediatric examination, including a careful neurological check-up; (3) Psychological examination using intelligence tests; (4) Electro-encephalographic examination according to standard techniques, with the patient awake, asleep and under photic stimulation; (5) Bi-weekly home visits to keep a record on intercurrent illness throughout the observation period. Statistical analysis of results shows significant differences between the groups in regard to the distribution of abnormalities.

Characteristics of 11 rabies virus isolates in mice: titers and relative invasiveness of virus, incubation period of infection, and survival of mice with sequelae.

Mice were inoculated intracerebrally or in the footpad with 11 salivary gland suspensions from rabid foxes, skunks, and bobcats. The 11 isolates differed in their ratios of intracerebral titer to footpad titer, a result indicating that the "invasiveness" of different isolates varies markedly. The degree of invasiveness could not be correlated with the species of animal. The inoculation of the less invasive isolates resulted in an appreciable number of permanently paralyzed animals (survivors with sequelae). These animals had high titers of neutralizing antibody in serum but no neutralizing antibody in the brain, a finding suggesting that virus had invaded only the peripheral nervous system or the spinal ganglia. Pathological examination of the paralyzed mice and normal mice confirmed this finding.

Do severe systemic sequelae of proteinuria modulate the antiproteinuric response to chronic ACE inhibition?

BACKGROUND: ACE inhibition exerts an antiproteinuric and renoprotective effect. However, residual proteinuria is often present. As residual proteinuria is associated with a poor renal outcome, identification of its determinants is important. We found previously that the systemic sequelae of proteinuria enhance renal damage in untreated nephrotic rats. The impact of systemic nephrosis on renal therapy response, however, is unclear. In the present study we therefore investigated whether the severity of systemic nephrosis, estimated from plasma cholesterol, predicts residual proteinuria during ACE inhibition. METHODS: Sixty male Wistar rats with established adriamycin nephrosis were studied. Six weeks after the induction of nephrosis, rats were stratified for proteinuria and treated for 2 weeks with lisinopril (75 mg/l) or vehicle. RESULTS: At the start of treatment, median proteinuria was 744 mg/day (95% confidence interval (CI) 609-860) and plasma cholesterol was 10.4 mmol/l (95% CI 8.0-12.6), reflecting the state of systemic nephrosis. Lisinopril, but not vehicle, reduced blood pressure and proteinuria (-62%; range -70 to -48; P<0.001). Residual proteinuria was 275 mg/day, with a wide range (47-1119 mg/day). Pre-treatment proteinuria and pre-treatment cholesterol correlated positively with residual proteinuria. By multivariate analysis (r(2) of model =0.92), both pre-treatment cholesterol and pre-treatment proteinuria were independent predictors of residual proteinuria. The quantitative impact of this multivariate analysis is illustrated by the difference in residual proteinuria between rats with a cholesterol:proteinuria ratio less than, compared with greater than, the median (residual proteinuria 298 mg/day (CI 129-496) vs 439 mg/day (CI 158-670), respectively). Blood pressure response was not predicted by the tested predictor variables. CONCLUSIONS: In this model of proteinuria-induced renal damage, not only proteinuria as such, but also the concomitant nephrotic alterations predict residual proteinuria. Further studies, applying specific interventions, are needed to determine which components of the systemic derangements could play a causal role in the modulation of therapy response.

A comparison of medical abortion (using mifepristone and gemeprost) with surgical vacuum aspiration: efficacy and early medical sequelae.

A total of 363 women undergoing legal abortion at < 63 days of amenorrhoea were allocated by a patient-centered, partially randomized study design to undergo medical abortion (using mifepristone 600 mg followed 48 h later by gemeprost 1 mg vaginal pessary) or vacuum aspiration (performed under general anaesthesia). The aim of the study was to compare the efficacy and complications of the two procedures. Main outcome measures included efficacy rates, medical complications within 21 days of abortion and unplanned family doctor consultation rates within 8 weeks following abortion. Sequelae such as pain, vaginal bleeding and recovery time were assessed by the change in haemoglobin level, the time taken to return to work or normal activity and the analgesic use. Results were gestation-related; at 50 days of amenorrhoea there was little to choose between the two procedures. At 50-63 days of amenorrhoea medical abortion becomes more painful and less effective, whereas vacuum aspiration retains high tolerance and efficacy. Women who are unsure which method to use are likely to find vacuum aspiration more acceptable at longer gestations.

Vietnam head injury study. Preliminary analysis of the functional and anatomical sequelae of penetrating head trauma.

An overview is presented of the multidisciplinary design, specific methods of motor and functional assessment, and selected preliminary data trends from the Vietnam Head Injury Study. This longitudinal study combines analyses of retrospective records with current, comprehensive inpatient examinations and investigates the anatomical and functional sequelae of penetrating head trauma in 700 Vietnam Veterans at an average of 14 years after injury. Preliminary data analysis of results from the first 160 subjects demonstrates good functional recovery despite large brain lesions. Motor abnormalities have persisted in 28 percent of the sample and are correlated with lesions involving the frontoparietal area of the cortex and the deep midline brain structures. Design concepts and long-term outcome trends will be useful to therapists in neurological rehabilitation. The study provides a model for health-team members interested in designs for longitudinal collection of outcome data.

Characterization of E-selectin expression, leucocyte traffic and clinical sequelae in urate crystal-induced inflammation: an insight into gout.

The self-limiting response to urate crystals allows the exploration of events involved in both the onset and resolution of gout. Using i.v. injected radiolabelled anti-E-selectin monoclonal antibody 1.2b6 together with differentially radiolabelled neutrophils, mononuclear cells and albumin, we have characterized the expression of E-selectin in relation to leucocyte traffic, microvascular permeability and clinical sequelae following intracutaneous injection of monosodium urate crystals. We found that the inflammatory response in this model involved several distinct phases. First, E-selectin expression increased over 2-6 h in the context of increases in neutrophil and mononuclear cell accumulation, and albumin leakage. Secondly, leucocyte accumulation rapidly declined despite persisting E-selectin expression. Thirdly, E-selectin expression peaked at approximately 8 h and then fell despite an increase in clinically detectable erythema and induration. Lastly, these clinical manifestations of inflammation resolved despite the continued presence of urate crystals in the tissues. The further dissection of mechanisms regulating these phases will lead to a better understanding of events in both the pathogenesis and resolution of gout. Of broader significance, this inflammatory model may yield information about the protective events that underly resolution of inflammation, and provide insights into factors which determine chronicity.

Amiodarone and radiation therapy sequelae.

With the aging of our population, amiodarone, a cardiac antiarrhythmic, is being used with increasing frequency. Anecdotal reports have appeared describing unexpected mucosal as well as cutaneous toxicity in patients treated concurrently with external beam radiotherapy and oral amiodarone. We retrospectively reviewed 12 years of experience at the University of Iowa Hospitals and Clinics and found 10 cases wherein amiodarone was taken concurrently with external beam radiation therapy. In our series, there were no missed treatment fractions because of unexpected acute sequelae. We conclude that amiodarone use does not preclude the delivery of therapeutic radiotherapy.

Functional sequelae of rhinoplasty.

Rhinoplasty is one of the most challenging surgical procedures. Surgeons should strive to obtain maximum aesthetic and functional results with minimal operative intervention. Excessive surgery often results in unwarranted impairment of nasal function. The obstructive or sensory complications of rhinoplasty can occur in the early or late postoperative periods. The most common functional sequelae of rhinoplasty, and their causes, prevention and therapy, are discussed.

Sequelae in the abdominal wall after pedicled or free TRAM flap surgery.

Twenty-seven free transverse rectus abdominis musculocutaneous (TRAM) and 16 pedicled TRAM flap breast reconstruction patients were studied for 7 to 41 months (mean, 23 months) postoperatively to compare abdominal sequelae after these two operations. The patient groups were demographically similar; mean age was 47 years in both groups. Subjective grading of the results was similar in both groups. The incidence of minor lower abdominal bulges was higher (44%, 7/16) in the pedicled group than in the free TRAM flap group (4%, 1/27). No hernias were found. Delayed healing of the abdominal scar occurred in 3 free TRAM flap and 1 pedicled TRAM flap patients. Two free TRAM flap (8%) and 7 pedicled TRAM (44%) flap patients had minor edge necrosis of the breast. Trunk strength was tested using an isokinetic device (Lido Multi Joint II), and peak torque for flexion (mean, 111 Nm +/- 25 Nm in the free TRAM flap group and 123 Nm +/- 28 Nm in the pedicled TRAM flap group) and extension (mean, 144 Nm +/- 38 Nm and 167 Nm +/- 45 Nm) were measured. No statistical differences occurred between these groups. Sit-up performance was tested and graded from 1 to 6. Both groups performed equally (4.8 and 4.8) and within normal values for this age group. Ultrasonography of the rectus muscles revealed that in the free TRAM flap group, the rectus muscle of the operated side was significantly thinner (cranial segment 6.8 mm vs. 7.8 mm, p < 0.05), thus the harvesting of a segment of muscle below the umbilicus seems to disturb the quality of the entire muscle. The mean size of the muscular defect in the free TRAM flap group was 4.3 x 6.1 cm. In this study no differences in patient satisfaction or trunk strength could be found between free and pedicled TRAM flap patients.

Cosmetic sequelae after conservative treatment for breast cancer: classification and results of surgical correction.

After conservative treatment for breast cancer, 20% to 30% of patients have a residual deformity that sometimes requires surgical correction. Thirty-five of these patients were operated between 1990 and 1995 at the Institut Curie. The authors classify these sequelae into three types: type I, asymmetrical breasts with no deformity of the treated breast; type II, deformity of the treated breast, compatible with partial reconstruction and breast conservation; and type III, major deformity of the breast, requires mastectomy. Fourteen patients had a type I deformity; all but 1 patient were treated with mammaplasty. Seventy-one percent underwent unilateral surgery contralateral to the irradiated breast; 80% had a satisfactory cosmetic result (good or very good). Seventeen patients had a type II deformity. They were treated by various techniques (implant, mammaplasty, latissimus dorsi flap, or transverse rectus abdominis musculocutaneous flap). Only 43.8% of patients in this group had a late satisfactory cosmetic result. Four patients had a type III deformity. They were treated with mastectomy and immediate reconstruction using a musculocutaneous flap. All 4 patients had a very good cosmetic result. This classification is a valuable guide for technique selection. For type I deformities, surgery to the irradiated breast should be avoided when possible. Type II deformities raise the most difficult therapeutic problems. Because they are mainly postoperative, optimal treatment should be preventive--by performing immediate remodeling of the treated breast before radiotherapy. This pleads for integration of plastic surgical techniques at the time of the original lumpectomy, thus reducing the need for delayed reconstructive surgery.

Iliac artery ligation: the relative paucity of ischemic sequelae in renal transplant patients.

In order to assess the effect of iliac artery ligation on the distal extremity, the ten year experience of the Johns Hopkins renal transplantation program was reviewed. Among 467 transplant procedures in 390 patients there were six cases in which the common and/or external iliac artery had been ligated for control of untoward hemorrhage from an infected arteriotomy site. These six cases were studied in detail with particular attention to ischemic sequelae in the involved leg. There were no immediate or causally-related deaths. No patient lost a leg or required an immediate reconstructive procedure for limb salvage. Four of the six recovered ambulatory status, and only two of these required a later, elective reconstruction for claudication. The combination of these six with eight other similar patients previously reported provides a total of 14 cases of iliac artery ligation in renal transplant patients. No patient suffered actual limb loss, and only three underwent subsequent elective reconstruction for claudication. It is concluded that common and/or external iliac artery ligation without immediate revascularization may be performed for control of hemorrhage with little danger of limb loss in renal transplant patients.

Prospective controlled vagotomy trial for duodenal ulcer: primary results, sequelae, acid secretion, and recurrence rates two to five years after operation.

In a prospective, controlled clinical trial, vagotomies for duodenal, pyloric, and prepyloric ulcers were performed on 259 patients. Eighty-three patients were randomly selected for truncal vagotomy and drainage (TV + D), 93 patients were randomly selected for selective gastric vagotomy and drainage (SV + D) and 83 patients were randomly selected for parietal cell vagotomy without drainage (PCV). This interim report deals with the primary results, reduction in acid secretion, sequelae, and recurrence rates two to five years after the operation. One patient died after the operation. Postoperative complications were evenly distributed between the three operations. No differences in spontaneous acid secretion (BAO), peak acid output after pentagastrin stimulation (PAOP), or peak acid output after insulin stimulation (PAOI) were found. Patients with recurrent ulcers ahd smaller reductions in BAO than patients without ulcer recurrences, although not significantly. Patients with ulcer recurrences after TV + D had, in contrast to ulcer recurrences after SV + D and PCV, a significantly smaller reduction in PAOP than patients without recurrences. The overall recurrence rate was 13%: 10% after TV + D, 14% after SV + D and 16% after PCV. The risk of ulcer recurrence within the first three years, calculated by an actuarial method, was found to be significantly higher after PCV (0.52% per month) than after TV + D (0.32% per month), but not different from SV + D (0.42% per month). In contrast to TV + D and SV + D, no recurrences after PCV occurred after three years--25% of the patients were followed for five years. It is concluded that the trial, at present, does not point to any evident superiority of PCV.

Sex offending as a psychosocial sequela of traumatic brain injury.

OBJECTIVE: To describe the nature and extent of sexual offending after traumatic brain injury (TBI). DESIGN: Retrospective file review. SETTING: A brain injury unit providing inpatient and outpatient rehabilitation services. PARTICIPANTS: A review of five years of admissions to the Brain Injury Rehabilitation Unit (N = 477) identified a sample of 29 males who committed 128 incidents of sex offending. MAIN OUTCOME MEASURES: A protocol to record data on demographic, injury, radiological, and psychosocial variables and offending behaviors. RESULTS: Of the total population of 445 clients with TBI, 6.5% (n = 29) were identified as having committed some form of sexual offense. Alcohol was a factor in only three (2.3%) of the incidents, and only two clients had a preinjury history of sexual offending. The most common offenses were the "touching" offenses, followed by exhibitionism and overt sexual aggression. Staff members were the most common targets of the offenses, followed by members of the general public, other people with TBI, and family members. CONCLUSIONS: Sex offending is a significant clinical problem among a small minority of men after TBI. The absence of alcohol and preinjury histories of sexual offending suggest that the brain injury and contingent sequelae were a significant etiological factor underlying the offenses. A number of implications for the clinical management of clients with sexually aberrant behaviors is identified and discussed.

Clinical experience in the treatment of noma sequelae.

We report a cohort of 148 African children operated on between 1985 and 2000 for noma sequelae. A total of 440 operations were performed. Lesions included mouth constriction in 70 of 148 cases, and severe bone destruction in 69 of 148 cases. A large proportion of children was transferred to Switzerland for surgical treatment, whereas the others were operated on in local hospitals in Africa. Vascularized calvarium flap was mostly used for bone reconstruction (n = 36). Pedicled latissimus dorsi myocutaneous flap was the preferred strategy for cheek reconstruction (n = 40). Expanded frontal flap was used for nasal reconstruction (n = 18), and pedicled heterolabial flap for lip construction (n = 37). Given the elevated level of recurrence of mouth constriction (extraarticular ankylosis), a minimum of 2 years' follow-up after surgical treatment was considered mandatory. Follow-up was conducted by field nurses from the humanitarian organizations, and a third of the patients were seen directly by our surgical team during special missions to Africa.

Avoiding the sequela associated with deformational plagiocephaly.

Over the last decade, infants with deformities in the craniofacial skeleton have been seen at our craniofacial center, and similar observations have been noted in infants seen for evaluation and management after birth, where there are not any evident pathological findings such as craniosynostosis or another known genetic disorder. The known condition of deformational plagiocephaly has been related to a sequela of the infants being placed on their back for sleep. The change in the position of the infants to sleep on their back was altered from the traditional position, where infants were placed in the prone position for many decades in the past in the Western world. A special study was initiated to compile meaningful data to help those in the field pursue their treatment of affected children in a systematic and comprehensive manner. Avoidance of unnecessary surgery was essential in those children unless the deformational condition persisted and was not resolvable by nonsurgical means and change in the cultural habitat.
