The chronic infection following internal fixation may develop in a different pattern, according to the risk factor involved. There is no doubt that direct trauma on bone and soft tissue is an important risk factor. The pattern of each infection may differ according to the technique of internal fixation used, i.e. external fixator, plate or intramedullary nailing. The damages are minimized by using the appropriate technique. While bone necrosis in osteomyelitis is present, the pattern of it may be changing. An infected non-union may occur in osteomyelitis (osteitis) when present before bone-healing took place. Should infection overlast the bone-healing period, the localization of the main focus is determinant for the outcome of the infection. The assessment of an osteomyelitis consists in the evaluation of the patient's general aspect and the extension of the infectious disease. Assessing it by plain radiographs, it might be accompanied by leucocyte scanning, CT-scan or MRI. The indication of a more aggressive treatment of chronic osteomyelitis is given in all cases of infected nonunion, chronicle fistulation and in presence of pain and contractures. Antibiotics should only be used in addition to a surgical procedure.

Dengue, a major public health problem throughout subtropical and tropical regions, is an acute infectious disease characterized by biphasic fever, headache, pain in various parts of the body, prostration, rash, lymphadenopathy, and leukopenia. In more severe or complicated dengue, patients present with a severe febrile illness characterized by abnormalities of hemostasis and increased vascular permeability, which in some instances results in a hypovolemic shock. Four distinct serotypes of the dengue virus (dengue-1, dengue-2, dengue-3, and dengue-4) exist, with numerous virus strains found worldwide. Molecular cloning methods have led to a greater understanding of the structure of the RNA genome and definition of virus-specific structural and nonstructural proteins. Progress towards producing safe, effective dengue virus vaccines, a goal for over 45 years, has been made.

We sought to determine the effects of Trichinella spiralis infection on small intestinal motor activity in the fasted state in dogs and relate it to clinical symptoms during the intestinal phase of trichinosis. Motor activity was recorded by strain gauge force transducers. Infection with T. spiralis resulted in a significant increase in the incidence and proximal origination of giant migrating contractions (GMCs) during the first 5 days postinfection. This was also the time when the dogs had diarrhea. The dogs were often restless and showed signs of discomfort during proximally originating GMCs. The incidence of retrograde giant contractions (RGCs) increased significantly on the 2nd and 3rd day postinfection. RGCs were followed by vomiting 71% of the time during infection. The migrating motor complex cycle length increased significantly, and this was due to intestinal "amyogenesia" and "dysmyogenesia". During these phenomena, electrical control activity was almost completely obliterated in the proximal half of the small intestine (amyogenesia) and became irregular and unstable in the distal half (dysmyogenesia). Intestinal amyogenesia and dysmyogenesia lasted up to 4 h and were terminated by a GMC. We conclude that diarrhea induced by T. spiralis infection is closely associated with an increase in the incidence and proximal origin of GMCs. These GMCs may also be the motor correlates of abdominal cramping and pain during the intestinal phase of trichinosis.

To evaluate patency, limb salvage rates and complications associated with the use of human umbilical vein as an arterial substitute, the authors carried out a retrospective review of 52 femorodistal bypasses performed over 9 years using human umbilical vein. Indications for operation included acute ischemia, rest pain and nonhealing ulceration or gangrene. There were 28 early occlusions, which resulted in a 1-month primary patency rate of 46% and a secondary patency rate of 52%. The primary and secondary patency rates at 1 year were 18% and 19% respectively. The mean limb salvage rate at 1 month was 57% and at 1 year 34%. Three aneurysms occurred (two anastomotic, one graft). Factors found to have a significant effect on patency rates were indication for operation and state of distal runoff. Infection occurred in 6% of grafts and led to amputation in every case. These disappointing results have caused the authors to discontinue use of human umbilical vein as an arterial substitute.

First metatarsophalangeal joint arthrosis may be associated with hallux valgus deformity. In an attempt to address the pain and deformities of this disorder, silastic implant arthroplasty combined with soft tissue balancing and proximal first metatarsal osteotomy has been performed on 17 feet in 11 patients. A retrospective review of the results at an average followup of 29.5 months is presented. Subjective pain relief has been satisfactory, and loss of correction of deformity has been minimal. Infection remains as a significant postoperative complication. This technique may be a treatment option in the low demand patient with a hallux valgus deformity, painful arthritis of the first metatarsophalangeal joint, and a wide first intermetatarsal angle.

We have reviewed 15 patients with infected total knee replacements after removal of the prosthesis, rigorous debridement, antibiotic irrigation, and prolonged systemic antibiotics. Infection was permanently eradicated in all patients; they were left with a functioning limb, on which they could walk with either a caliper (8 patients), a simple splint (3), crutches, or sticks. Three were disappointed because of residual pain. We believe that, if exchange arthroplasty is inappropriate, this procedure is preferable to arthrodesis or amputation for persistent and disabling infection, particularly where constrained artificial joints have been used.

Clostridium septicum is a major cause of spontaneous, nontraumatic gas gangrene. Unlike Clostridium perfringens, C. septicum is relatively aerotolerant and thus appears to be more capable of initiating infection in the absence of obvious damage to tissues. Six cases illustrate the clinical setting and fulminant nature of spontaneous gangrene caused by C. septicum. A lesion in the colon such as carcinoma is often present and is presumed to serve as a portal of entry to the bloodstream. Diabetes and leukopenia are also common predisposing conditions; compromise of vital host responses may facilitate proliferation of those organisms that settle out in the tissues. Acute lymphoma or leukemia during a course of chemotherapy is accompanied by damage to bowel mucosa and granulocytopenia, thus predisposing to spontaneous clostridial gangrene. Infection progresses in a fulminating manner; the majority of patients die within 24 hours of onset. Characteristic symptoms and signs include excruciating pain (although a sense of heaviness may be the only early symptom), swelling of tissues, crepitance, and bulla formation. A hallmark of C. septicum infection is the absence of acute inflammatory cells in involved tissues or in bulla fluid. A series of laboratory investigations demonstrated that fluid obtained from a bulla adversely affected the viability, morphology, and function of polymorphonuclear leukocytes (PMNs), which may explain the paucity of PMNs in involved tissues and may in part contribute to the fulminant progression observed in infection due to this organism.

Twenty-four total knee arthroplasty infections in 23 patients treated over a 9-year period at the University of Texas Medical Branch at Galveston were retrospectively reviewed. Staphylococcus epidermidis was isolated from 11 of 24 and Staphylococcus aureus from eight of 24 knees, respectively. Eleven infections were polymicrobic. Control of infection was obtained in 13 of 13 patients treated initially with resection arthroplasty, and 11 of these were ambulatory at follow-up. Infection was controlled in three of 10 knees treated initially with debridement, and six of these nine patients were ambulatory at follow-up. One patient was initially treated with amputation. Four of four patients treated by resection arthroplasty and then by reimplantation were ambulatory without signs of infection at follow-up. Resection arthroplasty reliably controls infection but produces a painful unstable joint that requires brace support or subsequent surgery for pain-free ambulation. Reimplantation in selected patients offers the best chance for pain-free ambulation.

A randomized, prospective study comparing the use of Biobrane (group 1) with the use of 1% silver sulfadiazine (group 2) in treating 56 partial-thickness burn wounds was carried out in 52 outpatients with burns that comprised less than 10% of their total body surface area. The two groups were similar in age, gender, race, and extent of burn. Wounds of patients in group 1 (30) were compared with those of group 2 (26) for healing time, pain, compliance with scheduled visits, and costs. Infected and skin-grafted wounds were excluded from healing time analysis. Infection rates of the two groups were similar (three of 30 vs two of 26). One patient in each group underwent skin grafting. Healing times of group 1 wounds were significantly less than those of group 2 (10.6 +/- 0.8 vs 15.0 +/- 1.2 days, P less than .01). Using a pain scale of 1 to 5, Biobrane-treated patients averaged lower pain scores at 24 hours after the burn (1.6 +/- 0.8 vs 3.6 +/- 1.3 P less than .001) and used less pain medication. Compliance with scheduled outpatient visits was also improved in the Biobrane-treated group (88.6% vs 63.2% attendance, P less than .001). Idealized total treatment costs averaged $434 for patients in group 1 compared with $504 for patients in group 2. We conclude that when used on properly selected wounds, Biobrane therapy can significantly decrease pain and total healing time without increasing the cost of outpatient burn care. Improved patient compliance may be an added benefit.

The pattern of illness in 60 consecutive children with homozygous sickle cell disease who attended the Paediatric Emergency Room of a busy Lagos hospital with acute illness was studied prospectively. Their ages ranged from 3 months to 13 years with a peak in the 2nd year. There were twice as many boys as girls. The commonest symptoms were fever, limb or abdominal pain and cough, and the commonest signs were pallor and hepatomegaly. Painful crises occurred in 27, anaemic crises in 11, and a combination of these in 12 children. Infection was detected in 76% of subjects in crises. Infection was found in 82% of all the children and was mainly bacterial. The commonest infections were pneumonia (35%), bacteraemia (32%), tonsillitis/pharyngitis (17%) and osteomyelitis (8%). The predominant bacteria isolated were Klebsiella spp (38%), E. coli (23%), Staph. aureus (23%), Staph. albus (23%) and Pseudomonas spp (23%). Some children had multiple isolates. Bacterial infection was a major cause of morbidity in very young children and merits appropriate control and preventive measures in this age group. The spectrum of bacteria isolated makes it unlikely that the specific anti-pneumococcal measures widely advocated in Europe and America for young children with SCA would be appropriate in Nigeria.
