The open mesh repair of Spigelian hernia.

BACKGROUND: Spigelian hernias are rare defects of the abdominal wall usually appearing between the abdominal muscles, lateral to the rectus abdominis and through a debilitated Spigelian aponeurosis. Recently, mesh repair has been introduced for the treatment of these types of hernias and different approaches have been proposed. METHODS: Nine patients with Spigelian hernia were prospectively treated by placing a mesh prosthesis between the external oblique and the internal oblique muscles, based on principles of mesh repair established by the Lichtenstein group. RESULTS: Five women and 4 men, mean age 75.7 years, were operated on. In 1 patient the Spigelian hernia was an incidental finding during an inguinal hernia repair. Two patients were operated on an emergency basis. Elective operations were undertaken in ambulatory facilities in 3. Two patients had postoperative ecchymosis with no associated morbidity. No recurrences have been observed during follow-up. CONCLUSIONS: Open mesh repair of Spigelian hernias placing the mesh between the external and internal oblique muscles is a simple and safe approach that can prevent morbidity related to other techniques.

Crimean-Congo hemorrhagic fever.

Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne disease caused by the arbovirus Crimean-Congo hemorrhagic fever virus (CCHFV), which is a member of the Nairovirus genus (family Bunyaviridae). CCHF was first recognized during a large outbreak among agricultural workers in the mid-1940s in the Crimean peninsula. The disease now occurs sporadically throughout much of Africa, Asia, and Europe and results in an approximately 30% fatality rate. After a short incubation period, CCHF is characterized by a sudden onset of high fever, chills, severe headache, dizziness, back, and abdominal pains. Additional symptoms can include nausea, vomiting, diarrhea, neuropsychiatric, and cardiovascular changes. In severe cases, hemorrhagic manifestations, ranging from petechiae to large areas of ecchymosis, develop. Numerous genera of ixodid ticks serve both as vector and reservoir for CCHFV; however, ticks in the genus Hyalomma are particularly important to the ecology of this virus. In fact, occurrence of CCHF closely approximates the known world distribution of Hyalomma spp. ticks. Therefore, exposure to these ticks represents a major risk factor for contracting disease; however, other important risk factors are known and are discussed in this review. In recent years, major advances in the molecular detection of CCHFV, particularly the use of real-time reverse transcription-polymerase chain reaction (RT-PCR), in clinical and tick samples have allowed for both rapid diagnosis of disease and molecular epidemiology studies. Treatment options for CCHF are limited. Immunotherapy and ribavirin have been tried with varying degrees of success during sporadic outbreaks of disease, but no case-controlled trials have been conducted. Consequently, there is currently no antiviral treatment for CCHF approved by the U.S. Food and Drug Administration (FDA). However, renewed interested in CCHFV, as well as increased knowledge of its basic biology, may lead to improved therapies in the future. This article reviews the history, epidemiology, ecology, clinical features, pathogenesis, diagnosis, and treatment of CCHF. In addition, recent advances in the molecular biology of CCHFV are presented, and issues related to its possible use as a bioterrorism agent are discussed.

Irreducible posterolateral knee dislocation resulting from a low-energy trauma.

A small amount of knee dislocations is included in the irreducible knee dislocations group. In such instance, medial femoral condyle is buttonholed through the gap formed by medial retinacular and capsular structures and this prevents reduction. In this study, we present two cases in which there were irreducible posterolateral knee dislocations resulting from a low-energy trauma. In both cases, dimple sign produced by the invagination of the medial retinacular structures and capsule and ecchymosis medially were noted. Soft tissue invaginated between the trochlea and intercondylar notch was extracted by open reduction.

Intra-lesional injections of collagenase are ineffective in the treatment of keloid and hypertrophic scars.

The treatment of keloid and hypertrophic scars remains difficult. Enzymatic digestion of keloid scars has been previously proposed as an effective treatment strategy for reducing the volume of keloid scars. To test this, we administered intra-lesional injections of pure collagenase (between 600 and 4500 units for each scar) into the keloid and hypertrophic scars of seven human volunteers (five keloid and two hypertrophic scars). Five patients (three keloid and two hypertrophic) received more than one injection of collagenase. The treatment resulted in a temporary reduction in scar volume for three of the patients with keloid scars. However, scar volumes for these three patients returned to the same (or greater) levels after 6 months of follow-up. Treatment with collagenase produced no change in scar volume for the two patients with hypertrophic scar. Side effects were numerous and severe including; pain, swelling, blistering, ulceration and ecchymosis at the site of injection. One patient required admission to hospital for 48 h after the first injection. Maximum length of follow-up was 6 months. None of the seven patients completed the study and returned for final follow-up at 2 years. This pilot study suggests that treatment of keloid and hypertrophic scars with intra-lesional injections of collagenase is ineffective.

Snake venom poisoning in Greece. Experiences with 147 cases.

BACKGROUND: Snake venom poisoning is a medical emergency requiring immediate attention. Bites from poisonous European snakes can lead to local tissue damage and systemic symptoms. Vipera ammodytes accounts for the most envenomation in Greece. METHODS: The demographic and epidemiological characteristics, clinical symptoms and signs, laboratory findings, treatment, and outcome of 147 consecutive victims of V. ammodytes admitted to our hospital from 1988 to 2003 were reviewed and analyzed. RESULTS: The most common symptoms and signs included fang marks (100%), pain (100%), swelling (98.64%), ecchymosis (60.54%), tachycardia (32.65%), fainting or dizziness (29.93%), fever (23.13%), enlargement of regional lymph nodes (17.69%), nausea (16.33%), hypotension (13.61%), and vomiting (12.93%). The main complications were reduced range of motion, thrombophlebitis, local hemorrhagic blister formation, skin bleeding, rhabdomyolysis, reduced sensation, acute renal failure, necrosis with tissue loss, carpal tunnel syndrome, compartment syndrome, Kounis syndrome, and digit amputation. CONCLUSIONS: A V. ammodytes bite is a potentially serious event that requires immediate hospital care. Yet, the majority of victims can be treated successfully with conservative methods. No deaths occurred in our series.

The role of facial trauma as a possible etiologic factor in temporomandibular joint disorder.

PURPOSE: Facial trauma has been suggested as a possible etiologic factor of temporomandibular joint disorder. However, there is little information on the role of macrotrauma. The main purpose of this study was to validate facial trauma as a potential etiologic factor for temporomandibular joint (TMJ) disorder. Multidirectional approaches were applied for the evaluation of the changes of TMJ after TMJ macrotrauma. PATIENTS AND METHODS: Analysis of TMJ status including arthroscopic examination, histomorphologic examination, and synovial fluid biochemical analysis were performed on the patients with mandibular fractures. Additionally, the efficacy of arthrocentesis for the patients of mandibular fracture was evaluated from the functional point of view. RESULTS: In arthroscopic examinations, evidence of synovitis with variable degrees was found. The representative findings are fibrillation and ecchymosis. On histomorphologic examination, bloody smear, degenerated cells and cartilage, inflammatory cells, and crystal were observed. In biochemical analysis, considerable amounts of prostaglandin E(2) and leukotriene B(4) were detected in the synovial fluid of the patients. CONCLUSION: The inflammatory and degenerative changes of TMJ can develop after facial trauma. Trauma can be a possible etiologic factor in cartilage degeneration, and biochemical and intra-articular pathology. Clinicians should recognize the etiologic importance of macrotrauma, and long-term evaluation of the TMJ as well as adequate treatment is required for patients with facial trauma.

Traumatic handlebar hernia: a rare abdominal wall hernia.

Traumatic abdominal wall herniation (TAWH) caused by direct trauma from bicycle handlebars are rare. There are only 21 reported cases of handlebar hernias. An 11-year-old boy presented to the emergency room soon after falling from his bicycle and hitting his right lower quadrant on the handlebars. The patient's vital signs and initial laboratory studies were normal. Physical exam showed a soft tissue bulge in the right lower quadrant with superficial ecchymosis and tenderness to palpation. Computed tomography showed intestinal loops protruding through a defect in the abdominal wall into the subcutaneous space. Surgical exploration found a defect throughout his entire abdominal wall including the fascia, muscular layers, and peritoneum, with bowel protruding into the subcutaneous space. The defect was repaired in layers, and the child's postoperative course was unevenful. The authors recommend a high level of clinical suspicion for TAWH in all patients with traumatic abdominal wall injuries. Definitive treatment includes surgical exploration with primary repair of all tissue layers of the abdominal wall.

Diffuse phlegmonous phlebitis after endovenous laser treatment of the greater saphenous vein.

Endovenous laser treatment (EVLT) has become a valuable and safe option in the treatment of varicose veins. Although long-term results are lacking, most patients seem to benefit in the short-term from EVLT. Reported postoperative complications are limited, consisting usually of pain, ecchymosis, induration, phlebitis, or spot skin burn injuries. The most feared complication is an extension of the saphenous thrombus into the femoral vein, with possible pulmonary embolism. Here we report a septic thrombophlebitis after EVLT resulting in a phlegmonous infection of the whole leg that was treated by surgical drainage. Aggressive local therapy and antibiotic treatment resulted in complete resolution of symptoms and eventual satisfactory healing.

Combined saphenous ablation and iliac stent placement for complex severe chronic venous disease.

BACKGROUND: Severe chronic venous disease frequently has a complex pathophysiology. This study describes results after combined interventions to correct outflow obstruction and superficial reflux, even in the presence of deep venous reflux. METHODS: Between 1997 and 2005, 99 limbs in 96 patients had percutaneous iliofemoral venous stenting combined with great saphenous vein (GSV) stripping (39 limbs), or percutaneous GSV ablation performed by radiofrequency (27 limbs) or laser (33 limbs). Clinical severity score in CEAP was C4 in 51 limbs, C5 in eight limbs, and C6 in 40 limbs; median age was 56 years (range, 27 to 87 years); left-right limb ratio, 2.3:1; female-male ratio, 1.8:1; primary-secondary etiology, 58:41. Perioperative investigations included visual analogue pain scale (VAS), degree of swelling (grade 0 to 3); quality-of-life questionnaire; venous filling index in milliliters per second (VFI90), venous filling time in seconds (VFT), percentage in ambulatory venous pressure drop (AVP), duplex Doppler scanning, and radiologic studies. RESULTS: Clinical follow-up was performed in 97 (98%) of 99 for up to 5.5 years. Axial deep reflux was found in 27% (27/99). At least three venous segments were refluxing in 40% of limbs. Preoperative hemodynamic parameters reflected the presence of reflux and improved significantly (P < .01) after the procedure (VFI90, 3.8 to 2.3 mL/s; VFT, 11 to 16 seconds; AVP, 55% to 65%). No patients died, and the morbidity with endovenous GSV ablation was largely limited to ecchymosis and thrombophlebitis in the thigh area. Cumulative primary, assisted primary, and secondary stent patency rates at 4 years were 83%, 97%, and 97%, respectively. After treatment, limb swelling and pain substantially improved. The rate of limbs with severe pain (>or=5 on VAS) fell from 44% to 3% after intervention. Gross swelling (grade 3) decreased from 30% to 6% of limbs. Cumulative analysis showed sustained complete relief of pain (VAS = 0) and swelling (grade 0) after 4 years in 73% and 47% of limbs, respectively. Ulcers healed in 26 (68%) of 38 ulcerated limbs. Cumulative ulcer-healing rate was 64% at 48 months. All quality-of-life categories significantly improved after treatment. CONCLUSION: The single-stage combination of percutaneous venous stenting and superficial ablation in patients with severe chronic venous disease is safe, gives excellent symptom relief and improvement of quality of life, and a well-maintained ulcer-healing rate. It seems logical to initially perform multiple minimally invasive interventions rather than open surgery. Any associated deep reflux can initially be ignored pending clinical response to the combined intervention.

Duvernoy's gland secretion of Philodryas olfersii and Philodryas patagoniensis (Colubridae): neutralization of local and systemic effects by commercial bothropic antivenom (Bothrops genus).

Colubrids involved in human envenomation in Brazil are mainly from the genera Helicops, Oxyrhopus, Thamnodynastes and Philodryas. There is a relatively large number of clinical descriptions involving the Xenodontinae snakes, Philodryas olfersii and Philodryas patagoniensis, in human accidents. The most common manifestations of envenomation are local pain, swelling, erythema and ecchymosis and regional lymphadenopathy with normal coagulation. The aims of this study were to characterize the biochemical and biological properties of P. olfersii and P. patagoniensis venoms, and to investigate their immunological cross-reactivities by using both specific antisera and anti-Bothrops sp serum used for human serum therapy in Brazil, in neutralizing the lethal and hemorrhagic effects of these venoms. We show here that P. olfersii e P. patagoniensis venoms present proteolytic and haemorrhagic activities but are devoid of phospholipase A2 activity. Haemorrhage and lethality induced by P. olfersii and P. patagoniensis are associated with metal-dependent proteinases, since EDTA could block these toxic activities. P. olfersii and P. patagoniensis venoms were immunogenic and the antisera produced were able to recognize several bands in P. olfersii, P. patagoniensis venoms in Bothrops jararaca venom.

Cutaneous manifestations in Italian kidney transplant recipients.

Several cutaneous disorders may occur in organ transplant recipients. We examined the incidence and the clinical spectrum of cutaneous manifestations among kidney transplant recipients. One hundred nine patients (70 males and 39 females), aged 19 to 69 years (mean: 42.5 years), were consecutively examined as outpatients between June 2000 and August 2004. The mean interval after kidney transplantation was 61 months (range: 2 to 120 months). The immunosuppressive regimen consisted of combinations including cyclosporine, systemic corticosteroids, azathioprine, tacrolimus, mycophenolate mofetil, antivirals, and antibiotics. Ninety-one cutaneous manifestations were identified in 60 of 109 (55.0%) kidney transplant patients over a 4-year period. Sixteen (17.5%) cutaneous viral infections identified in 11 patients (10.0%) included verruca vulgaris (n = 9), herpes zoster (n = 5) and herpes simplex (n = 2). Thirteen (11.9%) patients showed 19 (20.8%) superficial fungal infections, consisting of dermatophytosis (n = 6), onycomycosis (n = 6), pityriasis versicolor (n = 5) and mucocutaneous candidiasis (n = 2). Twenty (22%) nonmelanoma skin cancers were identified in seven (6.4%) patients, six basal cell carcinomas (BCC) in four patients, two squamous cell carcinomas (SCC) in two patients, and 11 BCCs in addition to one SCC in one patient. Twenty-six (23.8%) patients developed 32 (35.4%) drug-related manifestations, including acneiform eruption (n = 14), gingival hypertrophy (n = 6), hypertrichosis (n = 6), ecchymosis (n = 3), and plantar hyperkeratosis (n = 3). In addition, psoriasis and seborrheic dermatitis, which had been diagnosed before kidney transplantation, were observed in five and three patients, respectively. Our results emphasize the importance of dermatologic examinations and monitoring kidney transplant recipients to obtain an early diagnosis and treatment of cutaneous manifestations.

Current recommendations for imaging in the management of urologic traumas.

Three percent to 10% of trauma patients have genitourinary tract injuries. Radiologic imaging is essential for making the correct diagnosis and managing it appropriately. Which modality is appropriate is based on the mechanism of injury and patient presentation. Patients with pelvic injuries and gross hematuria should undergo either CT cystography or conventional cystography. Ultrasound is warranted in patients with scrotal trauma when physical exam is inconclusive. Patients with penetrating trauma to the external genitalia, who suffer blunt trauma to the penis, or who present with gross hematuria, blood at the meatus, inability to void, perineal/scrotal ecchymosis, or abnormal digital rectal exam should undergo retrograde urethrography. Using these criteria for imaging should lead to the proper diagnosis and minimize patient morbidity.

Etiology and incidence of pressure ulcers in surgical patients.

This experimental study was designed to identify the etiology of pressure ulcers in a surgical sample and to evaluate a special OR mattress overlay in preventing pressure ulcer development. Surgical patients (N = 413) were randomized to receive "usual perioperative care" or the new mattress overlay. Over six postoperative days, 89 patients (21.5%) developed pressure ulcers, primarily stage I. Only 2% developed stage II or IV ulcers. Patients with ulcers were statistically older, had diabetes, were smaller in body mass, had lower Braden Scale scores on admission, and used the new mattress overlay (P < .02). Pressure ulcers that presented as "burns" or ecchymosis did not deteriorate to stage III or IV ulcers during the study. The mattress overlay was not effective in preventing pressure ulcer development.

Prospective comparison of hemorrhagic complications after treatment with enoxaparin versus unfractionated heparin for unstable angina pectoris or non-ST-segment elevation acute myocardial infarction.

Patients with unstable angina pectoris (UAP) or non-ST-segment elevation acute myocardial infarction (AMI) are at risk of death or recurrent ischemic events, despite receiving aspirin and unfractionated heparin (UFH). This study investigates the effect of the low molecular weight heparin, enoxaparin, on the incidence of hemorrhage and thrombocytopenia in relation to baseline characteristics and subsequent invasive procedures. Rates of hemorrhage and thrombocytopenia were analyzed for UAP or non-ST-segment elevation AMI in patients included in the prospective, randomized, double-blind Efficacy and Safety of Subcutaneous Enoxaparin in Non-Q-wave Coronary Events (ESSENCE) study. Patients received either enoxaparin or UFH, plus aspirin, for 2 to 8 days. The overall rate of major hemorrhage (at 30 days) was comparable between the 2 groups (6.5% for enoxaparin vs. 7.0% for UFH, p = 0.6). The rate of major hemorrhage while on treatment was slightly higher in the enoxaparin group, but this was not significant (1.1% vs 0.7% for UFH, p = 0.204), as was the rate of major hemorrhage within 48 hours of coronary artery bypass grafting performed within 12 hours of treatment. However, the rate of minor hemorrhage was significantly higher in the enoxaparin group, with the majority being injection-site ecchymoses or hematomas (11.9% vs. 7.2% with UFH, p <0.001). Thrombocytopenia (platelet count <100,000 per mm(3)) occurred mainly in association with coronary bypass surgery, with a similar rate in both groups. Thus, enoxaparin is a well-tolerated alternative to UFH in the management of UAP or non-ST-segment elevation AMI. Despite the more effective antithrombotic effect, which results in fewer ischemic events, enoxaparin is not associated with an increase in the rate of major hemorrhagic complications, and is not significantly associated with thrombocytopenia, but is associated with an increase in minor injection site ecchymosis.

Patterns of genital injury in female sexual assault victims.

OBJECTIVE: New colposcopic protocols allow examiners to better document genital trauma in rape victims. We report our findings on the locations and types of genital injury seen in female assault victims versus women engaging in consensual sex. STUDY DESIGN: Physical examinations were performed on 311 rape victims seen by San Luis Obispo County's Suspected Abuse Response Team between 1985 and 1993 and contemporaneously on 75 women after consensual sexual intercourse. RESULTS: Among 213 (68%) victims with genital trauma, 162 (76%) had 3.1 mean sites of injury. Comparatively, 8 (11%) consenting women had just single-site trauma. Two hundred (94%) victims had trauma at one or more of four locations, as follows: posterior fourchette, labia minora, hymen, fossa navicularis. Trauma types varied by site; tears appeared most often on the posterior fourchette and fossa, abrasions appeared on the labia, and ecchymosis was seen on the hymen. CONCLUSION: A localized pattern of genital trauma can frequently be seen in women reporting nonconsensual sexual intercourse; such findings are useful for the clinical forensic examiner.

Retinal and choroidal vascular occlusion after posterior sub-tenon triamcinolone injection.

PURPOSE: To report a case of retinal and choroidal vascular occlusion occurring as a complication after posterior sub-Tenon triamcinolone injection for treatment of uveitic cystoid macular edema. DESIGN: Interventional case report. METHODS: Retrospective study. A 32-year-old woman with uveitis and cystoid macular edema underwent a right posterior sub-Tenon injection of triamcinolone (40 mg/ml, 1 ml total) through a superotemporal approach after topical anesthesia. After the procedure, the patient experienced severe eye pain, orbital ecchymosis, and globe proptosis consistent with retrobulbar hemorrhage. RESULTS: Dilated fundus examination of the right eye (OD) demonstrated multiple intraretinal hemorrhages with particulate white emboli occluding the retinal and choroidal vessels. Visual acuity was no light perception. Ocular massage and hypotensive therapy was initiated for an intraocular pressure of 50 mm Hg. Canthotomy and cantholysis were performed. A total of 39 months post-incident, her visual acuity improved to 20/100. CONCLUSION: Posterior sub-Tenon triamcinolone injection can rarely result in retinal and choroidal occlusion. Immediate intervention may preserve limited visual acuity.

Isolated unilateral neurogenic blepharoptosis secondary to eyelid trauma.

PURPOSE: To describe eyelid trauma as a cause of isolated neurogenic blepharoptosis. DESIGN: Observational case series. METHODS: Three previously healthy patients (two male and one female; aged 29 to 39 years) were evaluated for unilateral blepharoptosis following forceful anterior displacement of the upper eyelid. Two injuries occurred during domestic altercations and one while the patient was playing basketball. RESULTS: All three patients had complete unilateral upper eyelid ptosis with no levator palpebrae superioris function, consistent with loss of innervation. Additional findings included minimal eyelid ecchymosis, eyelid edema, and subconjunctival hemorrhage in two cases. The remainder of the examinations was unremarkable with full ocular motility and no anisocoria. Without treatment, within 2 weeks, all three patients recovered completely with normal symmetric lid height and levator function. CONCLUSIONS: Isolated neurogenic blepharoptosis may result from traumatic anterior upper eyelid displacement. Resolution is likely within 2 weeks.

Scalpel neodymium:YAG laser in oculoplastic surgery.

In a three-year study, the scalpel Nd:YAG laser was compared with conventional surgery in 18 patients who underwent oculoplastic surgery. The postoperative follow-up was at least eight months. The contact Nd:YAG laser had distinct advantages over conventional surgery in the treatment of vascular orbital tumors, including less perioperative bleeding and a shorter operating time. In other oculoplastic procedures, ten of the 18 patients underwent surgery with the scalpel Nd:YAG laser on one side and conventional surgery on the other side. There was less bleeding, a shorter operating time, and less pain on removal of orbital fat on the laser-treated side. The postoperative scarring was initially more noticeable on the Nd:YAG laser-treated side, but after three months there was no appreciable difference in scar formation between the two sides. The amount of postoperative edema and ecchymosis did not appear to be significantly different with the Nd:YAG laser compared with conventional surgery. Additionally, microscopic evaluation showed minimal charring of tissues with the Nd:YAG laser.
