Anterior lumbar fusion utilizing transvertebral fibular graft.

In those instances of failed posterior arthrodesis for spondylolisthesis, iatrogenic spondylolisthesis due to posterior neural decompression or severe (grade III or IV) spondylolisthesis, anterior stabilization using a fibular strut graft appears to be feasible and successful. Eleven patients were treated with this technique and ten achieved solid anterior arthrodesi; the eleventh fused posterolaterally. All improved symptomatically with no postoperative complications, including sexual dysfunction in the male.

Perinatal medical negligence closed claims from the St. Paul Company, 1980-1982.

One hundred fifty-three closed claims involving perinatal injury or death filed from 1980 through 1982 with the St. Paul Fire and Marine Insurance Company were studied. The claims included were those in which an indemnity was paid or $1,000 or more was expended on the legal defense. Five obstetricians reviewed these cases to identify obstetric and neonatal risk factors. In addition, cases were classified as to the presence or absence of medical negligence. Most of the complications leading to claims arose during labor and delivery. Many claims resulted from the failure to evaluate or treat in a manner consistent with accepted standards of care. Many lacked documentation of the physician's recognition of the risk factors involved. Low Apgar scores at both one and five minutes were the newborn risk factors seen most commonly. In the opinion of the reviewers, medical negligence occurred in 47% of the cases. Indemnity payment occurred with most of the claims judged to be associated with medical negligence. Payment to the claimant was made in a number of cases in which the reviewer thought no malpractice occurred. These results suggest that improvements may be needed in prenatal and perinatal health care as well as in the legal system used to address the problem of perinatal medical negligence.

The role of arthroscopic surgery in the evaluation of acute traumatic hemarthrosis of the knee.

Eighty patients presented for evaluation with an acute traumatic hemarthrosis of the knee and negligible instability on clinical examination. All had an examination under general anesthesia followed by arthroscopy. Anatomical lesions were demonstrated in 71 of 80 knees (89%) including anterior cruciate ligament (ACL) disruption in 50 (62%). Twenty-nine of 50 patients (58%) with arthroscopically-demonstrated ACL injuries had associated meniscal tears. Fifteen (19%) demonstrated isolated meniscal tears and nine (11%) osteochondral fractures not detected by conventional roentgenograms. The frequent occurrence of injuries to other joint structures in conjunction with ACL injuries was remarkable. An acute traumatic hemarthrosis of the knee often masks significant lesions. Arthroscopy aids the orthopedic surgeon in determining the full extent of the intraarticular damage.

Investigation of obstetric malpractice closed claims: profile of event.

The files of 220 obstetric closed-claim cases were reviewed by five obstetricians to determine whether information could be collected an analyzed to identify common predisposing factors to claims and to suggest preventative measures. The data suggests these cases contain common easily identified obstetric risk factors, most of which occurred in labor and delivery (66%). Fifty-four percent of the risks were recognized, 32% correctly managed, and a high percentage of risks were considered by the reviewers to be directly related to the obstetric outcome leading to the claim (66%). The authors feel obstetric closed claims can be studied and suggestions made to aid obstetricians in providing care. Identification of common obstetric risks and correct management of these risks is poor in these cases. Recognition and management guidelines are imperative in ensuring good obstetric outcome. These two physician-controlled factors played important parts in the majority of cases reviewed. It would appear from this study that obstetric malpractice closed claims are amenable to study; physicians and their patients would benefit from better data collection systems to identify risks in individual pregnancies; physicians need readily available resources to aid their management of patients; only through modification of physician behavior can suits be avoided.

Magnesium sulfate and beta-mimetic dual-agent tocolysis in preterm labor after single-agent failure.

Twenty-three patients in preterm labor failed to respond to single-agent tocolytic therapy or could not tolerate the dosage necessary to inhibit contractions. A combination of magnesium sulfate and ritodrine or terbutaline was used to inhibit labor in these patients. Fourteen patients (60.9%) responded to dual-agent tocolysis by delaying delivery for 48 hours or more. Six patients had delivery delayed for more than one week. Five patients had multiple gestations; three of them had delivery delayed more than 48 hours. Five patients developed pulmonary edema under treatment with dual-agent tocolysis; all responded to diuretic and/or oxygen therapy after the termination of tocolysis. Dual-agent tocolysis may significantly prolong some pregnancies complicated by preterm labor, but only at some risk to maternal well-being.

Endometrial aspiration in fertility control. A report of 500 cases.

Outpatient endometrial aspiration was offered to patients who suspected that they were pregnant, but were within 5 to 21 days after failure of expected menstruation and had a uterus of normal size on pelvic examination. This is a report of 500 consecutive cases treated between September, 1973, and April, 1975. Histologic examination of the aspirated tissue was obtained on all 500 cases (100 per cent). Follow-up examination and urine pregnancy was obtained on 407 patients (81.4 per cent). Histologic evidence of pregnancy was obtained in 323 patients (64.6 per cent). Complications were limited to five infections (1 per cent), only one of which led to hospitalization of the patient, and failure to completely evacuate the pregnant uterus in 39 patients (12.1 per cetn of the 323 pregnant). Thirty-four of these had the uterus emptied by a second outpatient procedure and five patients were hospitalized to complete their abortion.

Prematurity and orgasmic coitus during pregnancy: data on a small sample.

Nineteen mothers of premature infants were interviewed in an attempt to determine a possible relationship between prematurity and orgasmic coitus during pregnancy. Although the limited number of subjects precludes tests of statistical significance and definite conclusions, the findings do suggest possible associations. While there appeared to be no relationship between prematurity and coitus per se during pregnancy, the association of frequent or intense orgasm with prematurity does raise some questions that further investigation might answer. Because of the hazard of prematurity to the subsequent development of the child, further exploration of the possible relationship of prematurity to orgasmic coitus during pregnancy appears warranted.

Effectiveness of pneumococcal polysaccharide vaccine for preschool-age children with chronic disease.

To estimate the effectiveness of pneumococcal polysaccharide vaccine, we serotyped isolates submitted to the Pneumococcal Sentinel Surveillance System from 1984 to 1996 from 48 vaccinated and 125 unvaccinated children 2 to 5 years of age. Effectiveness against invasive disease caused by serotypes included in the vaccine was 63%. Effectiveness against serotypes in the polysaccharide vaccine but not in a proposed seven-valent protein conjugate vaccine was 94%.

Emerging infectious diseases in Alaska and the Arctic: a review and a strategy for the 21st century.

Emergence of new, previously unknown, and drug-resistant infectious diseases pose a major threat to global health. The emergence of infectious diseases in Alaska and the Arctic parallels the resurgence of infectious diseases worldwide. The Centers for Disease Control and Prevention has developed a strategy to revitalize the capacity to protect the public from emerging infectious diseases by improving four major public health activities: surveillance and response, applied research, infrastructure and training, and prevention and control. The plan targets high-priority emerging infectious disease problems and particular groups of people at increased risk. These target areas encompass a number of diseases of special concern in Alaska, such as drug-resistant Streptococcus pneumoniae infections, foodborne botulism, alveolar hydatid disease, viral hepatitis, Helicobacter pylori infections, Haemophilus influenzae type b bacteremia and meningitis, and infections of immunocompromised persons, pregnant women and newborns, and tourists. To address these and other emerging infectious disease issues, including the threat of bioterrorism in Alaska and the Arctic, future issues of Alaska Medicine will include updates on specific emerging infectious diseases for health care providers, clinical laboratory workers, and community public health professionals who form the front lines for recognizing, treating, and preventing emerging infectious diseases.

The challenge of ongoing Haemophilus influenzae type B carriage and transmission in Alaska.

Cases of invasive Haemophilus influenzae type b disease in Alaskan children quickly dropped 10-fold after widespread vaccination with a conjugate vaccine (PRP-OMP) began in 1991. However, reemergence of invasive disease in 1996-97 soon followed a change to a combination diphtheria-tetanus toxoid-pertussis/H. influenzae type b vaccine which incorporates a different conjugate vaccine (HbOC). Previously unrecognized persistence of H. influenzae type b carriage in rural Alaska, coupled with characteristics of the immune response to HbOC, are the likely explanations for disease reemergence. The current vaccine recommendation--PRP-OMP for the first dose, followed by HbOC to complete the vaccination series--appears to protect Alaskan infants even in the face of continuing carriage and transmission. Successful control of invasive H. influenzae type b disease in Alaskan children will require not only appropriate immunization, but also continuing surveillance for both disease and carriage, identification of factors associated with carriage, and investigation into the feasibility of using vaccination plus antimicrobial drugs to eliminate this pathogen.
