The most important side effects of oral contraceptives (OCs) and their incidence, together with advice and monitoring of the patient at risk, are pointed out. There is a mild increase in blood pressure in longterm contraceptive use caused by increased angiotensinogen production by the liver. It is significant only for women with a history of familial hypertension, diabetes mellitus, or pre-eclampsia. Smoking increases this risk. Urinary tract infections are 25-50% more frequent in pill users. Glucose tolerance is slightly decreased. Contraceptives' diabetogenic effect is higher in women with hereditary tendency for diabetes, latent diabetes, and/or obesity. They are contraindicated in latent diabetes. Findings are contradictory in their effects on cholesterol and triglyceride serum level, but the pill is contraindicated in lipid metabolism disorders. There is an increased incidence in cholecystitis and cholelithiasis in pill-users (70-80 additional cases/100,000 user years). Liver diseases, intrahepatic cholestasis, occur rarely and benign liver tumors have not conclusively been proved to be caused by the pill. A variety of laboratory findings have been related to contraceptive use and drug interactions occur with barbiturates, rifampicin, hydantoin, and phenylbutazone. Blood coagulation is increased, partially by increased production of various blood coagulation factors; but more importantly, by a decreased synthesis of antithrombin III, a natural protective mechanism against intravascular coagulation. This increases thrombosis risk. Risk doubles with simultaneous cigarette smoking. Various epidemiological studies indicate a 5-10 fold increase in thromboembolism and thrombophlebitis, deep vein thrombosis, and pulmonary embolism. There is a correlation between contraceptive use and cerebrovascular disorders and myocardial infarction. This risk increases with age and years of pill use. The pill is contraindicated with symptoms of thrombophlebitis and thromboembolism, sickle cell anemia, proposed surgery, and longterm immobilization. Overall risk factors are not too high. Recommendations for rational pill use related to age are given and further contraindications are mentioned.

In a retrospective review of pregnancy and delivery in 8 spinal cord damaged women managed at Hexham General Hospital Spinal and Maternity Units between 1986 and 1991, antenatal complications included urinary tract infection, anaemia, constipation, suspected deep venous thrombosis and pressure sores. Five of the 8 patients had adductor spasms. Autonomic hyperreflexia occurred in 2 patients in the antenatal period, and in one patient in the postpartum period. Four patients were delivered by caesarean section, and 4 of the 8 patients had breech presentation of the foetus at delivery. The perinatal outcome was good.

One hundred thirty-seven consecutive posterior stabilized total knee arthroplasties (TKAs) were reviewed. Average age of the patient was 61.1 years and length of postoperative follow-up period was 29.2 months. Patients were evaluated using the Hospital for Special Surgery (HSS) knee rating scores. Average preoperative scores improved from 52 to 92, postoperatively. Ninety-eight percent of patients had no pain or mild occasional pain postoperatively compared with 99% of patients experiencing severe to disabling pain preoperatively. Complications included one myocardial infarction, two deep venous thrombosis, one urinary tract infection, one patellar dislocation, and four wound problems. There were two incidences of seroma, one hematoma, and one deep infection requiring revision after joint debridement and systemic antibiotics. Also noted was one incidence of ligamentous laxity and one patella fracture.

A retrospective review covering a 9-year period revealed 113 patients who underwent 157 major bowel procedures during 130 operations performed solely by gynecologic oncology surgeons. Forty-eight percent of the operations were done for tumor cytoreduction, and 33% were performed for a bowel obstruction. Other indications included colostomy closure, fistula repair, resection for multiple enterotomies, temporary diversions, repair of perforated bowel, treatment for severe proctosigmoiditis, management of ureteral stricture, treatment for vulvar necrosis, and resection of an incidental small bowel tumor. Of the 157 procedures, 44% were colostomies, 32% were bowel resections with reanastomosis, 9% were urinary conduits, 6% were intestinal bypass procedures, 5% were colostomy closures, and 4% were ileostomies. Postoperative complications occurred in 32% of the 130 operations. These included wound infection, death, sepsis, fistula formation, urinary tract infection, unexplained febrile morbidity, anastomotic leakage, stomal infarction, adult respiratory distress syndrome, bowel obstruction, deep venous thrombosis, and wound hematoma. Four of the eight deaths were due to tumor progression, three were from sepsis, and one was from adult respiratory distress syndrome. Of the 130 operations, 89 (68%) were associated with no complications. These data support the concept that gynecologic oncology surgeons are able to perform intestinal operations as therapy for gynecologic malignancies with acceptable complication rates. Since a thorough understanding of the natural history of the cancer, familiarity with alternative therapeutic options, and knowledge of the prognosis are important in making operative decisions, and since gynecologic oncologists are technically capable of performing operations on the small bowel and colon, referral of patients with a primary or recurrent gynecologic malignancy or with a subsequent intestinal complication after initial therapy should be directed to the gynecologic oncologist whenever possible.

Hip surgery is the most common major orthopedic procedure performed in the elderly. The indications are fracture and pain secondary to degenerative arthritis. Patients undergoing hip replacement for arthritis have excellent outcomes with decreased pain, increased mobility, and a low mortality. Age should not be a contraindication to hip replacement, with patient selection being made on the basis of symptomatology and overall health. In hip fracture, the prognosis is more guarded. Poor functional outcome results from complications of the fracture, such as avascular necrosis of the femoral head and fracture nonunion in femoral neck fractures and instability with delayed weight bearing in intertrochanteric fractures. In addition, patients sustaining hip fracture are more likely to have significant comorbidity and subsequent perioperative complications. Pressure ulcers, delirium, deep venous thrombosis, urinary retention and urinary tract infection, and cardiac events are the most frequent complications seen. These complications can be anticipated and prevented with careful preoperative assessment and post-operative prophylactic management. A team approach including the orthopedic surgeon, primary care physician, nursing staff, and physical therapists is essential for optimal outcome.

From 1975 to 1986, 2435 patients were admitted to the Northwestern University-Midwest Regional Spinal Cord Injury Unit. Of these, 220 patients (9.0%) had documented neck fractures from diving accidents, representing the largest series of acute diving injuries yet analyzed. The average age of these patients was 21 years, and males predominated. Two hundred twelve patients (96.4%) were admitted within 48 hours of injury. Associated injuries were rare: none had intracranial mass lesions or systemic injuries, and only nine were near-drowning victims who required endotracheal intubation. The most common levels of injury were C-5 (140 fractures) and C-6 (85 fractures), with 70 patients having fractures at more than one level. Neurological injury was sustained in 154 (70.0%) patients, while 66 (30.0%) patients were neurologically intact. One hundred forty-seven (66.8%) patients underwent posterior cervical fusion, and anterior fusion was performed in 36 (16.4%), allowing for early ambulation and an average hospital stay of 17 days. Hospitalization was relatively uncomplicated, with urinary tract infection in 121 (55.0%), pneumonia in nine (4.1%), and deep vein thrombosis in 24 (10.9%). Long-term follow up averaged 5 years and was obtained in 160 (72.7%) patients. Sixteen (10.0%) improved neurologically, five (3.1%) deteriorated, and 139 (86.9%) were unchanged. Notably, this large study shows that diving accidents occur in a young, healthy population who sustain essentially no other associated intracranial or systemic injuries and have few serious hospital complications. Such patients may be mobilized early in their care after either internal or external stabilization. Subsequent long-term neurological improvement can be expected to occur in about 10% of patients. The importance of water safety and injury prevention is stressed.

Deep venous thrombosis is a frequent, well-recognized complication of spinal cord injury. Patients with myelomeningocele often have similar weakness of the lower extremities. Following orthopedic surgery, they may also be immobilized at a time when they are hypercoagulable. In addition, as with patients with spinal cord injury, patients with myelomeningocele are prone to urinary tract infection, which may cause local inflammation in the pelvic veins. For the first time, three patients with myelomeningocele complicated by deep venous thrombosis are described. The differential diagnosis (deep venous thrombosis vs osteomyelitis vs fracture) is also discussed in a child with myelomeningocele and a warm, swollen leg, as are the diagnostic methods available. Finally, the issue of antithrombotic prophylaxis in patients with myelomeningocele who are to undergo extensive orthopedic surgery is discussed.

Immunoreactive thromboxane B2 (i-TXB2) was measured in daily urine samples from twelve patients after renal transplantation. In 21 of 30 rejection episodes, the increase in i-TXB2 preceded both the increase in serum beta 2-microglobulin (beta 2-MG) and the clinical diagnosis of rejection. In 26 of 30 rejection episodes, the increase in urine i-TXB2 preceded the increase in serum creatinine. The degree of change in i-TXB2 is greater than that of either serum beta 2-MG or creatinine. Urinary i-TXB2 was very high in one patient with deep venous thrombosis, but it did not rise in patients with urinary tract infection, pneumonia, or acute tubular necrosis. Thus, urinary i-TXB2 seems to be an early indicator of clinical renal allograft rejection.

The pattern of postoperative pyrexia in Khartoum was prospectively studied in 260 patients who underwent a variety of surgical operations. Ninety four patients (36.1%) developed postoperative pyrexia. The commonest causes of pyrexia encountered were wound sepsis (10%), malaria (9.6%) and respiratory tract infection (7.3%). Less frequent causes were urinary tract infection, thrombophlebitis, intra-abdominal sepsis and deep vein thrombosis. In 14.6% of the patients, the cause of pyrexia was undetermined. The risk factors for postoperative pyrexia were the patient's age, diabetes mellitus, obesity, preoperative chest infection, smoking, duration of surgery, operator's surgical experience and urethral catheterisation. The postoperative pyrexia was associated with 7.4% mortality rate which was due to intra-abdominal sepsis and pulmonary embolism. The incidence of postoperative pyrexia can be minimised by adequate preoperative preparation, meticulous surgical technique and good postoperative care.

This self-directed learning module highlights new advances in understanding medical complications of spinal cord injury through the lifespan. It is part of the chapter on spinal cord injury rehabilitation in the Self-Directed Physiatric Education Program for practitioners and trainees in physical medicine and rehabilitation. This article covers reasons for transferring patients to specialized spinal cord injury centers once they have been stabilized, and the management of common medical problems, including fever, autonomic dysreflexia, urinary tract infection, acute and chronic abdominal complications, deep vein thrombosis, pulmonary complications, and heterotopic ossification. Formulation of an educational program for prevention of late complications is also discussed, including late renal complications, syringomyelia, myelomalacia, burns, pathologic fractures, pressure ulcers, and cardiovascular disease. New advances covered in this section include new information on old problems, and a discussion of exercise tolerance in persons with tetraplegia, the pathophysiology of late neurologic deterioration after spinal cord injury, and a view of the care of these patients across the lifespan.
