Recombinant human factor VIIa prevents hysterectomy in severe postpartum hemorrhage: single center study

Abstract Objective: To evaluate the effectiveness of human recombinant activated factor VII (rhFVIIa, NovoSeven) in avoiding hysterectomy postpartum in the management of severe postpartum hemorrhage (PPH). Methods: We performed a prospective cohort study at our university tertiary care center. Patients with severe post partum hemorrhage (blood loss >2000 mL) and failed medical and uterus-preserving surgical management, were treated with intravenous bolus administration of rhVIIa. Main outcome measures were cessation of bleeding, postpartum hysterectomy and thromboembolic events. Results: In 20/22 patients included, PPH was caused primarily by uterine atony, including 7 (32%) with additional lower genital tract lesion; in two women, it was due to pathologic placentation (placenta increta, 9%). One case of amniotic fluid embolism and one woman with uterine inversion were included. Recombinant hFVIIa was successful in stopping the PPH and in preventing a hysterectomy in 20/22 women (91%). The remaining two patients with persistent bleeding despite rhFVIIa treatment, who underwent postpartum hysterectomy, had placenta increta. No thromboembolic event was noticed. Conclusions: This study describes the largest single center series of rhFVIIa treatment for fertility preservation in severe postpartum hemorrhage published to date. Our data suggest that administration of rhFVIIa is effective in avoiding postpartum hysterectomy after conservative medical and surgical measures have failed. Although randomized studies are lacking, rhFVIIa should be considered as a second-line therapeutic option of life-threatening postpartal bleeding, in particular if preservation of fertility is warranted and hysterectomy is to be avoided.

Asymptomatic ossifying fibroma of the mandible: a case presentation

Ossifying fibromas are rare benign bone-related lesions of the jaw. Early diagnosis based on clinical, radiologic, and pathohistologic findings is essential, since undetected lesions may expand and cause considerable functional and cosmetic problems. The treatment of choice is purely surgical. Periodic clinical and radiologic follow-up should be scheduled, since recurrence is possible. The present article describes the diagnostic procedures, surgical management, and follow-up of an asymptomatic ossifying fibroma in the mandible of a 21-year-old man.

[Joint preserving surgery of the adult hip: pelvic osteotomies]

Deformity and malposition of the acetabulum can occur during the development of the hip. Developmental hip dysplasia and acetabular retroversion are possible causes of osteoarthritis in the young adult. Surgical management with reorientation of the acetabulum allows causal therapy of the deformity and preservation of the native hip joint. Established techniques are the Bernese periacetabular osteotomy (PAO) and the Tönnis and Kalchschmidt triple osteotomy of the pelvis. Both techniques permit three-dimensional correction of the position of the acetabulum. Advantages and disadvantages of each technique must be considered and are summarized in the present paper. If performed early (osteoarthritis grade Tönnis 0 and 1) with correct indication and proper technique, good results can be expected.

[Radical prostatectomy in the treatment of organ confined prostate cancer]

Open radical prostatectomy represents one possible therapeutic option for treating patients with clinically localized prostate cancer Patient selection and the surgical management have undergone important changes during the last years, resulting in lower morbidity and probably in a better tumor control due to a better standardisation of the surgical technique. Long-term functional outcome regarding continence and potency are of increasing importance and influence mainly the quality of life in these patients. Open radical retropubic prostatectomy remains the gold standard in patients with localized prostate cancer, due to its low morbidity and excellent oncological and functional results. The value of laparoscopic and robotic radical prostatectomy is still discussed controversially. Due to the relative high morbidity during the so-called learning curve and the lack of long-term oncological and functional results, these techniques seem to show less favourable results.

Monitoring eines Hundes mit traumatischem Hämoabdomen durch serielle Messung von abdominalem und peripher venösem Hämatokrit

Objective: This case report describes the use of serial measurements of peripheral venous and abdominal fluid hematocrits as a guide to treatment in a dog with traumatic hemoabdomen. Material and methods: An 18-month-old, female mixed-breed dog was presented with traumatic hemoabdomen. The dog was treated with intravenous fluids, and concurrent measurements of venous and abdominal fluid hematocrits were performed. Results: The initial hematocrit values were 39% in venous blood and 42% in abdominal fluid. Following fluid therapy, the venous hematocrit decreased to 20%, whereas the abdominal hematocrit remained stable at 40%. Based on this finding severe ongoing intra-abdominal hemorrhage was ruled out, and the dog was treated conservatively. Conclusion and clinical relevance: Comparison of serial abdominal and venous hematocrits may be useful in assessing the need for surgical management in patients with traumatic hemoabdomen.

Parotid tumors: fine-needle aspiration and/or frozen section

OBJECTIVE: The purpose of this study was to analyze and compare the value of fine-needle aspiration cytology (FNAC) and frozen section (FS) analysis in the assessment of parotid gland tumors. STUDY DESIGN: Chart review and cross-sectional analysis. SUBJECTS AND METHODS: FNAC and FS analysis of 110 parotid tumors, 68 malignancies and 42 benign tumors, were analyzed and compared with the final histopathologic diagnosis. RESULTS: The accuracy, sensitivity, and specificity of FNAC in detecting malignant tumors were 79 percent, 74 percent, and 88 percent, respectively. On FS analysis, the accuracy, sensitivity, and specificity in detecting malignant tumors were 94 percent, 93 percent, and 95 percent, respectively. The histologic tumor type was correctly diagnosed by FNAC and FS in 27 of 42 (64%) and 39 of 42 (93%) benign tumors, respectively, and in 24 of 68 (35%) and 49 of 68 (72%) malignant neoplasms, respectively. CONCLUSION: The current analysis showed a superiority of FS compared with FNAC regarding the diagnosis of malignancy and tumor typing. FNAC alone is not prone to determine the surgical management of parotid malignancies.

Role of nutrition in liver transplantation for end-stage chronic liver disease

Patients with end-stage liver disease often reveal significant protein-energy malnutrition, which may deteriorate after listing for transplantation. Since malnutrition affects post-transplant survival, precise assessment must be an integral part of pre- and post-surgical management. While there is wide agreement that aggressive treatment of nutritional deficiencies is required, strong scientific evidence supporting nutritional therapy is sparse. In practice, oral nutritional supplements are preferred over parenteral nutrition, but enteral tube feeding may be necessary to maintain adequate calorie intake. Protein restriction should be avoided and administration of branched-chain amino acids may help yield a sufficient protein supply. Specific problems such as micronutrient deficiency, fluid balance, cholestasis, encephalopathy, and comorbid conditions need attention in order to optimize patient outcome.

Canalicular adenoma of a minor salivary gland on the palate: a case presentation

Canalicular adenomas are uncommon, benign epithelial neoplasms of the salivary glands that usually involve the upper lip and buccal mucosa of elderly people. Differential diagnosis of the canalicular adenoma versus adenocarcinoma is important, as it may result in unjustified radiotherapy or extensive and aggressive surgery. Despite the benign nature of canalicular adenomas, complete surgical removal and a regular clinical follow-up are recommended. The present article describes the diagnostic procedures, surgical management, and follow-up of a canalicular adenoma involving the palate of a 71-year-old man.

Atraumatic splenic rupture in amyloidosis

BACKGROUND: Splenic involvement in amyloidosis is rather frequent (5-10%). An atraumatic rupture of the affected spleen is however an extremely rare event. We report on a patient with undiagnosed amyloidosis who underwent emergency splenectomy for atraumatic splenic rupture. METHODS: Review of the literature and identification of 31 patients, including our own case report, with atraumatic splenic rupture in amyloidosis. Analysis of the clinical presentation, the surgical management, the nomenclature and definition of predisposing factors of splenic rupture. RESULTS: We identified 15 women and 16 men (mean age 53.3 +/- 12.4 years; median 52, range: 27-82 years) with an atraumatic splenic rupture. Easy skin bruisability and factor X deficiency were detected in four (13%) and five patients (16%), respectively. The diagnosis of splenic rupture was made either by computed tomography (n = 12), ultrasound (n = 5), exploratory laparotomy (n = 9) or autopsy (n = 4). All patients underwent surgery (n = 27) or autopsy (n = 4). Amyloidosis was previously diagnosed in nine patients (29%). In the remaining 22 patients (71%), the atraumatic splenic rupture represented the initial manifestation of amyloidosis. Twenty-five patients (81%) suffered from primary (AL) and four patients (13%) from secondary amyloidosis (AA). In two patients, the type of amyloidosis was not specified. A moderate splenomegaly was a common feature (68%) and the characteristic intraoperative finding was an extended subcapsular hematoma with a limited parenchymal laceration (65%). In five patients with known amyloidosis, the atraumatic splenic rupture was closely associated with autologous stem-cell transplantation (ASCT) (16%). Three patients were suffering from multiple myeloma (10%). A biopsy-proven amyloidotic liver involvement was present in 14 patients (45%), which lead to atraumatic liver rupture in two patients. The splenic rupture related 30-day mortality was 26% (8/31). CONCLUSIONS: Atraumatic splenic rupture in amyloidosis is associated with a high 30-day mortality. It occurs predominantly in patients with previously undiagnosed amyloidosis. A moderate splenomegaly, coagulation abnormalities (easy skin bruisability, factor X deficiency) and treatment of amyloidosis with ASCT are considered predisposing factors for an atraumatic splenic rupture.

Minimal-invasive percutaneous reduction and transsacral screw fixation for U-shaped fractures

STUDY DESIGN Technical note and case series. OBJECTIVE To introduce an innovative minimal-invasive surgical procedure reducing surgery time and blood loss in management of U-shaped sacrum fractures. SUMMARY OF BACKGROUND Despite their seldom appearance, U-shaped fractures can cause severe neurological deficits and surgical management difficulties. According to the nature of the injury normally occurring in multi-injured patients after a fall from height, a jump, or road traffic accident, U-shaped fractures create a spinopelvic dissociation and hence are highly unstable. In the past, time-consuming open procedures like large posterior constructs or shortening osteotomies with or without decompression were the method of choice, sacrificing spinal mobility. Insufficient restoration of sacrococcygeal angle and pelvic incidence with conventional techniques may have adverse long-term effects in these patients. METHODS In a consecutive series of 3 patients, percutaneous reduction of the fracture with Schanz pins inserted in either the pedicles of L5 or the S1 body and the posterior superior iliac crest was achieved. The Schanz pins act as lever, allowing a good manipulation of the fracture. The reduction is secured by a temporary external fixator to permit optimal restoration of pelvic incidence and sacral kyphosis. Insertion of 2 transsacral screws allow fixation of the restored spinopelvic alignment. RESULTS Anatomic alignment of the sacrum was possible in each case. Surgery time ranged from 90 to 155 minutes and the blood loss was <50 mL in all 3 cases. Two patients had very good results in the long term regarding maintenance of pelvic incidence and sacrococcygeal angle. One patient with previous cauda equina decompression had loss of correction after 6 months. CONCLUSIONS Percutaneous reduction and transsacral screw fixation offers a less invasive method for treating U-shaped fractures. This can be advantageous in treatment of patients with multiple injuries.

The role of postoperative antibiotics in facial fractures: Comparing the efficacy of a 1-day versus a prolonged regimen

BACKGROUND The goal of this study was to evaluate the influence of the duration of postoperative antibiotics (1 day vs. ≥ 5 days) on wound infections following surgical treatment of facial fractures. METHODS Three hundred thirty-nine patient case histories with a total of 498 fractures were reviewed retrospectively with regard to infections occurring within a 6-month period following surgical management. Patients were divided into two groups based on the duration of postoperative antibiotics administered. Group A consisted of 125 patients who had 1 day of postoperative antibiotics, whereas Group B consisted of 214 patients who had five or more days of postoperative antibiotics. Statistical analysis was conducted to assess for possible differences in the rate of postoperative infections. RESULTS Five patients in Group A (4%) and seven patients in Group B (3.27%) developed infections within the follow-up period. Of these 12 patients, seven had sustained multiple facial bone fractures. Eleven infections occurred in patients with mandibular fractures and one in a midfacial fracture. Statistical analysis using Fisher's exact test showed no significant difference (p = 0.77) in the incidence of infection between Groups A and B. CONCLUSION In this retrospective study, the use of prolonged postoperative antibiotics in uncomplicated mandibular and midfacial fractures had no significant benefit in reducing the incidence of infections. LEVEL OF EVIDENCE Therapeutic study, level IV.

The ARCH Projects: design and rationale (IAASSG 001).

OBJECTIVE A number of factors limit the effectiveness of current aortic arch studies in assessing optimal neuroprotection strategies, including insufficient patient numbers, heterogenous definitions of clinical variables, multiple technical strategies, inadequate reporting of surgical outcomes and a lack of collaborative effort. We have formed an international coalition of centres to provide more robust investigations into this topic. METHODS High-volume aortic arch centres were identified from the literature and contacted for recruitment. A Research Steering Committee of expert arch surgeons was convened to oversee the direction of the research. RESULTS The International Aortic Arch Surgery Study Group has been formed by 41 arch surgeons from 10 countries to better evaluate patient outcomes after aortic arch surgery. Several projects, including the establishment of a multi-institutional retrospective database, randomized controlled trials and a prospectively collected database, are currently underway. CONCLUSIONS Such a collaborative effort will herald a turning point in the surgical management of aortic arch pathologies and will provide better powered analyses to assess the impact of varying surgical techniques on mortality and morbidity, identify predictors for neurological and operative risk, formulate and validate risk predictor models and review long-term survival outcomes and quality-of-life after arch surgery.

Anterior fixation of unstable pelvic ring fractures using the modified Stoppa approach: mid-term results are independent on patients' age

PURPOSE Open surgical management of unstable pelvic ring injuries has been discussed controversially compared to percutaneous techniques in terms of surgical site morbidity especially in older patients. Thus, we assessed the impact of age on the outcome following fixation of unstable pelvic ring injuries through the modified Stoppa approach. METHODS Out of a consecutive series of 92 patients eligible for the study, 63 patients (mean age 50 years, range 19-78) were evaluated [accuracy of reduction, complications, failures, Majeed-Score, Oswestry Disability Questionnaire (ODI), Mainz Pain Staging System (MPSS)] at a mean follow-up of 3.3 years (range 1.0-7.9). Logistic multivariate regression analysis was performed to assess the outcome in relation to increasing patient age and/or Injury Severity Score (ISS). RESULTS Out of 63 patients, in 36 an "anatomic" reduction was achieved. Ten postoperative complications occurred in eight patients. In five patients, failure of fixation was noted at the anterior and/or posterior pelvic ring. In 49 patients, an "excellent" or "good" Majeed-Score was obtained; the mean ODI was 14 % (range 0-76 %); 50 patients reported either no or only minor chronic pelvic pain (MPSS). Only an increasing ISS conferred an increased likelihood of the occurrence of a non-anatomical reduction, a "poor" or "fair" Majeed-Score, or an ODI >20 %. CONCLUSIONS Increasing age did not impact the analysed parameters. Open reduction and internal fixation of the anterior pelvic ring through a modified Stoppa approach in unstable pelvic ring injuries did not result in an unfavourable outcome with increasing age of patients.

Nail melanoma in situ: clinical, dermoscopic, pathologic clues, and steps for minimally invasive treatment

BACKGROUND Nail unit melanoma (NUM) is a variant of acral lentiginous melanoma. The differential diagnosis is wide but an acquired brown streak in the nail of a fair-skinned adult person must be considered a potential melanoma. Dermoscopy helps clinicians to more accurately decide if a nail apparatus biopsy is necessary. OBJECTIVE Detailed evaluation of clinical and dermoscopy features and description of conservative surgery of in situ NUM. METHODS Retrospective study of in situ NUM diagnosed and treated with conservative surgical management in the authors' center from 2008 to 2013. RESULTS Six cases of NUM were identified: 2 male and 4 female patients, age range at diagnosis of 44 to 76 years. All patients underwent complete nail unit removal with at least 6-mm security margins around the anatomic boundaries of the nail. The follow-up varies from 4 to 62 months. CONCLUSION Nail unit melanomas pose a difficult diagnostic and therapeutic challenge. Wide excision is sufficient, whereas phalanx amputation is unnecessary and associated with significant morbidity for patients with in situ or early invasive melanoma. Full-thickness skin grafting or second-intention healing after total nail unit excision is a simple procedure providing a good functional and cosmetic outcome.

Total Thyroidectomy for Amiodarone-induced Thyrotoxicosis in the Hyperthyroid State.

Amiodarone is a potent antiarrhythmic agent, indicated for the treatment of refractory arrhythmias, which may lead to thyrotoxicosis. In these patients, thyroidectomy is a valid therapeutic option. Antithyroid therapy in the immediate preoperative setting and the subsequently accepted minimal delay until thyroidectomy have not been clearly defined yet. The aim of the present study was to show, that total thyroidectomy under general anaesthesia in patients with amiodarone-induced thyrotoxicosis (AIT) is safe without necessarily obtaining an euthyroid state preoperatively.We conducted a retrospective cohort study of prospectively gathered data on 11 patients undergoing total thyroidectomy under general anaesthesia between January 2008 and December 2013 for AIT at our University Hospital.All patients were preoperatively treated with carbimazole, steroids and β-receptor antagonists. Additionally, 3 patients received potassium perchlorate and in one patient carbimazole was changed to propylthiouracil. Plasmapheresis was performed in 3 patients. Only one patient was euthyroid at the time of operation. There were no significant intra- and postoperative complications, especially no signs of thyroid storm. One patient could postoperatively be removed from the cardiac transplant waiting list due to improved cardiac function.Improvements in the interdisciplinary surgical management for AIT between cardiologists, endocrinologists, anaesthetists and endocrine surgeons provide the basis of safe total thyroidectomy under general anaesthesia in hyperthyroid state. Early surgery without long delay for medical antithyroid treatment (with its potential negative side effects) is recommended.
