A new autogenous graft choice in pelvic reconstructions: free vascularized rib (a case report).

Primary or secondary bone tumours are not uncommon in pelvic girdle. In some cases, after radical resection, there is a big bony defect where the prosthesis is not applicable; arthrodesis is the only choice for good functional results. In this instance, the major problem is to achieve the fusion. In this case report, we focused on easy harvesting and minimal time consumption with free vascularized rib graft to achieve the fusion between the resected segments. Two year follow up showed fusion with good functional result.

Titanium mesh fracture in mandibular reconstruction.

Mandibular reconstruction is important for providing good functional and cosmetic results after the resection of a mandibulary segment. Reconstruction plates and titanium meshes are usually used to reconstruct the bony defects in mandible. Although their complications are well known there is not a report on the fractures of a titanium mesh after mandible reconstruction in the literature. We reported a case of a broken titanium mesh after mandible reconstruction.

The effect of delayed admission in burn centers on wound contamination and infection rates.

BACKGROUND: Since wound infection rates in patients with delayed admission seemed to be significantly higher, a retrospective study of bacteriology in 320 burn patients, over a 5-year period was carried out in order to analyze the relation between delayed admission and wound infection rates in our Burn unit of Uludağ University, Faculty of Medicine. METHODS: The patients were separated into moderate or major burn groups according to burn severity. Wound infection and contamination frequencies were analyzed according to time-delay between burn injury and hospitalization time. RESULTS: Delayed admission was found to be an important factor that causes an increase in wound infection and contamination frequency. This increase was significant especially among patients with moderate burn wounds. In patients with severe burns, wound infection and contamination frequencies were found to be higher for all admission time points. CONCLUSION: Systemic antibiotic prophylaxis should be discussed in patients with moderate burns whose admission-delay is more than 78 hours. Wound infection and contamination rates were high in patients with major burns independent of the admission time. Therefore, systemic antibiotic prophylaxis should also be discussed in this group of patients, although it results in elimination of the normal skin flora.

Using the sac membrane to close the flap donor site in large meningomyeloceles.

If a large transposition flap with or without muscle is used for closure of a large meningomyelocele defect, then, a part of the donor site of the flap can be closed by split thickness skin graft, which produces an additional donor wound for the patient. We used the sac membrane instead of split thickness skin graft for closure of donor sites of fasciocutaneous flaps and latissimus dorsi musculocutaneous flaps employed to cover large meningomyelocele defects. This technique was used in three thoracolumbar and in two lumbosacral meningomyelocele patients. The sac membrane was prepared like a full thickness skin graft. Follow-up in five patients has ranged from 1 to 18 months, with a mean of 10.6 months. The donor sites that were closed by the sac membrane exhibited complete healing in all patients. We conclude that the sac membrane supplies a reserve of epithelialised tissue that can be used for repair of the meningomyelocele defects.

Thermal injuries due to paint thinner.

This study was designed to evaluate the epidemiology and outcome of burn injuries due to paint thinner in a local burn center. During a 10-year period, 32 patients were admitted to our Burn Unit for paint thinner thermal burn. Patients were reviewed regarding the age, sex, etiologic factors, extent and localization of burn, treatment methods, length of hospitalization, and results. There were 30 males and 2 females. The mean age of patients was 25.9 +/- 11 years. The most common etiologic factor was kindling a fire with paint thinner. The mean extent of burn was 33.6 +/- 24% of the total body surface area. All patients sustained burn injury on the face, arms, and hands and five patients among them had extended burn areas on the trunk and/or lower extremity. The mean length of hospitalization for the survivors was 34.5 +/- 21.6 days. Twenty-eight patients were treated by early excision and split-thickness skin grafting. In four patients, burn wounds were healed by conservative management. Five patients with burn size of over 75% of the total body surface area died. In conclusion, paint thinner may be the cause of a catastrophic thermal injury and should not be used for the purpose of kindling fire.

[A retrospective analysis of 204 mandibular fractures].

BACKGROUND: We retrospectively reviewed patients who were treated and followed-up for mandibular fractures within a 10-year period. METHODS: A total of 204 patients (158 males, 46 females; mean age 22.4 years; range 5 to 72 years) were retrospectively evaluated with respect to age groups, sex, etiology, associated injuries, localization and type of the fractures, treatment methods, and early and late complications. The follow-up period ranged from four months to 10 years. RESULTS: The most common cause of injury was traffic accidents (44.1%), followed by falling (31.8%), and violence (17.1%). The highest incidence occurred at ages 21 to 30 years. Of 283 fractures detected, the most common fracture sites were the parasymphysis (83 fractures, 29.3%) and the angulus (52 fractures, 18.4%). Forty-eight patients (24%) had associated injuries. The type of the fractures was simple in 80 patients (39.2%), and complex in 62 patients (30.4%). Treatment included open reduction with titanium mini-plates and screws in 130 patients, and intermaxillary fixation in the remaining patients. The fractures recovered without any complications in 167 patients (81.8%). No occlusion-related complications occurred in the late follow-ups. Complications were encountered in 37 patients (18.1%), being in the early (malocclusion in 5.9%, infections in 2.5%, inferior alveolar nerve injuries in 2.5%) or late (plate-screw exposition in 4.4%, ankylosis of the temporomandibular joint in 2%, and orocutaneous fistula in 1%) postoperative periods. CONCLUSION: Rigid fixation should be the first choice of treatment in mandibular fractures.

[The prognostic value of the Hand Injury Severity Score in industrial hand injuries].

BACKGROUND: We evaluated the value of the "Hand Injury Severity Score" (HISS) in determining the prognosis of industrial hand injuries. METHODS: Hand injury severity scores of 112 patients (17 females, 95 males; mean age 31 years; range 15 to 54 years) were calculated following surgery for industrial hand injuries. During the course of rehabilitation program, the patients were followed-up regularly. Pearson correlation coefficients were used to determine the relationship between the HISS scores and the time intervals from injury to healing and return to work. RESULTS: The mean HISS score was 37.1+/-27 (range 6 to 116). The time to healing ranged from 12 to 210 days (mean 73.7+/-40.7 days). All the patients returned to work after a mean of 80.4+/-52.9 days (range 7 to 300 days), mainly to previous working places with (12%) or without (79%) changing job activities. Nine per cent of the workers had to change their jobs. The HISS scores were found to be correlated with the healing period and the time to work (p<0.05 and p<0.000, respectively). CONCLUSION: The results of this study indicated that HISS was a useful system in predicting the prognosis in the early stages of industrial hand injuries.

[Clinical evaluation and treatment results of 30 patients with necrotizing fasciitis].

BACKGROUND: We retrospectively evaluated patients who underwent treatment for necrotizing fasciitis within a five-year period. METHODS: Thirty patients (4 females, 26 males; mean age 55 years; range 19 to 78 years) with necrotizing fasciitis were evaluated with respect to age, sex, etiology, predisposing factors, localization of infections, culture results, and treatment methods and results. RESULTS: The most common etiologic and predisposing factors were anorectal lesions (36.7%) and diabetes (53.3%), respectively. Wound cultures yielded Pseudomonas aeruginosa in 50% of the patients. Two strains of aerobic bacteria were isolated in three patients. All patients underwent extensive surgical debridement and received antibiotic therapy. Twenty-nine patients (96.6%) required more than one debridement, with a mean of 4.5 debridements. The ensuing skin defects following debridement were reconstructed with grafts or local flaps. No complications were encountered in the postoperative period. CONCLUSION: Early diagnosis and treatment result in decreased morbidity and prevent mortality in necrotizing fasciitis.

Using a plastic sheet to prevent the risk of contamination of the burn wound during the shower.

The shower technique for hydrotherapy was used in the treatment of the burn patients in our burn center. Before showering, the shower trolley (stretcher) was draped with a sterilized disposable plastic sheet to decrease the potential for seeding surface bacteria to open burn wounds. The patients were washed on the draped shower trolley. Samples for culture were taken from the surface of the shower trolley (stretcher) before it was draped with the sterilized disposable plastic sheet following the treatment of a patient. The samples were taken once a week for the first 6 months and only once a month for the last 42 months. At the period of 48 months (4 years), a total of 67 samples were obtained. Results of cultures of all the samples were negative. No patients were contaminated from the surface of the shower trolley during the shower. The use of the sterilized disposable plastic sheet proved to be a most effective procedure to decrease the risk of contamination between patients during the shower.

V-Y advancement island flap based on the perforator of the anterior interosseous artery.

The limited sliding capacity of the V-Y advancement flaps has always been a problem. The mobility and reliability of the V-Y flap have been enhanced by raising it as an island flap based on perforators of the axial arteries in the extremities. The author elevated a new V-Y advancement island flap based on the dorsal perforator of the anterior interosseous artery on the dorsal aspect of the forearm for the dorsal defects of the wrist. This flap was used in the reconstruction of the dorsal defects of the wrist after tumor resection in two patients. Dissection was performed over the dorsal muscle fascia until the perforator was seen. The fascia was only incised all around the perforator. The donor sites were closed primarily in a V-Y fashion together with split thickness skin graft in patient 1 and only in a V-Y fashion in patient 2. The patients were followed-up from 13 to 15 months. All flaps survived completely. This flap is an alternative option for closure of medium to large defects on the dorsum of the wrist.

A new flap design for monitoring the circulation of a buried free radial forearm flap in pharyngoesophageal reconstruction.

The viability of a free radial forearm flap which is used in pharyngoesophageal reconstruction is difficult to monitor because it is hidden by skin. As the most reliable method for monitoring, exteriorization of a small island flap has been reported. The authors used a skin paddle which is placed ulnar to the radial forearm reconstruction flap at the ulnar side of the distal part of the forearm as a monitor flap in one patient. Flap viability was assessed by observing tissue color, turgor, capillary refill, and bleeding of the monitor flap. This monitor flap is easy to elevate. The perfusion of the flap is good because it has a wide pedicle. It permits a long vascular pedicle for the radial forearm reconstruction flap and does not reduce available forearm skin for pharyngoesophageal reconstruction.

Osteocutaneous posterior interosseous flap for reconstruction of the metacarpal bone and soft-tissue defects in the hand.

A vascularized bone segment of the ulna together with a posterior interosseous fasciocutaneous flap is harvested, including a cuff of the extensor pollicis longus muscle. The authors treated five male patients with metacarpal bone and soft-tissue defects of the hand using a distally based island osteocutaneous posterior interosseous flap. Their ages at the time of surgery ranged from 15 to 37 years (mean, 24 years). The bone defects were in the first metacarpal in three cases, the fourth metacarpal in one, and the fifth metacarpal in one. The length of the donated ulna ranged from 3 to 7 cm (mean, 5 cm). The follow-up period ranged from 5 to 92 months (mean, 39 months). All flaps survived completely. The posterior interosseous flap provides thin skin of good texture, together with vascularized bone, for a one-stage reconstruction of the metacarpal bone and soft-tissue defects in the hand.

An unusual cause of burn injury: fig leaf decoction used as a remedy for a dermatitis of unknown etiology.

Medicinal plant extracts are commonly used worldwide. Their use relies mostly on historical and anecdotal evidence and might be so hazardous. Phytophotodermatitis is a well-known entity that is caused by the sequential exposure to certain species of plants containing furocoumarins and then to sunlight. In this article, superficial burn lesions caused by fig leaf decoction that was applied to a patient's both upper extremity as a remedy for a dermatitis of unknown etiology is reported. Direct sun exposure is an essential component of phytophotodermatitis. All reported cases to date have in common that patients are exposed to direct sunlight or to artificial UVA lights (like solarium) of varying durations. In our case neither direct sun exposure, other than inevitable indoor UVA influence, nor blister formation was present. The etiologic factors, symptoms, signs, course, and treatment alternatives for phytophotodermatitis are also reviewed briefly.
