Foreign rectal body - Systematic review and meta-analysis.

BACKGROUND: Self-inserted foreign rectal bodies are an infrequent occurrence, however they present a serious dilemma to the surgeon, due to the variety of objects, and the difficulty of extraction. The purpose of this study is to give a comprehensive review of the literature regarding the epidemiology, diagnostic tools and therapeutic approaches of foreign rectal body insertion. METHODS: A comprehensive systematic literature review on Pubmed/ Medline and Google for 'foreign bodies' was performed on January 14th 2018. A meta-analysis was carried out to evaluate the epidemiology, diagnostics and therapeutic techniques. 1,551 abstracts were identified, of which 54 articles were included. RESULTS: The motivation of foreign rectal body insertion is mostly sexual stimulation. Patients are typically young and predominantly male, with a male to female ratio of 6:1. Sexual devices (35.7%, n=108) and glass objects (17.5%, n=53) are the most commonly self-inserted rectal foreign bodies. Patient history should be taken sensitively after diagnostic evaluation and identification of the object. Removal was performed under general anesthesia in 45.2% (n=95) and sedation in 29.0% (n=61). The total complication rate was described to be 30.4%. CONCLUSIONS: Diagnostics must be performed with caution in order to rule out perforation and establish a treatment algorithm. Manual transanal extraction under sedation or general anesthesia may be performed in conjunction with cautious abdominal compression. Because of the variety of objects, i.e. in form and material, each case must be treated individually. Sometimes creativity and surgeon imagination may be required, although different algorithms have been established.

Pedicled hypothenar perforator flap: Indications and clinical application.

BACKGROUND AND AIM: Soft-tissue defects of the palm and the palmar aspect of the fifth finger are a constant problem in reconstructive hand surgery. We present a possible approach to planning and harvesting pedicled hypothenar perforator flaps for the reconstruction of such defects. METHODS: A hypothenar perforator flap was used to reconstruct a soft-tissue defect on the ulnar aspect of the palm and the palmar aspect of the fifth finger of 17 patients. The defects were located over the proximal phalanx of the fifth finger (n = 9), the palm (n = 5), and across both areas (n = 3). The size of the defects was up to 7.9 cm(2). RESULTS: Eleven of the flaps healed primarily, out of which partial flap necrosis was observed in six. Four of these six flaps required operative revision, including debridement and delayed primary wound closure, while two healed secondarily. After an average of 26.6 days (range 21-45 days), all 17 patients achieved complete functional recovery. Despite the complications described, all the primary defects remained covered. CONCLUSION: The pedicled hypothenar perforator flap is an option for reconstruction of ulnar-sided, soft-tissue defects of the palm and little finger. The flap is thin and the donor-site morbidity is low. Hand surgeons may wish to consider this flap when presented with soft-tissue defects in this area.

One night in a snowbank: a case report of severe hypothermia and cardiac arrest.

Hypothermia < 28 degrees C is rarely compatible with life, with only a few cases described surviving such low temperatures. We present a case of a man who survived with a core body temperature below 21.0 degrees C after spending a night in a snowbank with an ambient temperatures as low as -20.0 degrees C. Prolonged CPR and early initiation of extracorporeal membrane oxygenation enabled survival without neurological deficit at hospital discharge. Frostbite was limited to both hands and all toes only; although the entire upper and lower extremity appeared to be deeply frozen on admission, amputation of both hands was inevitable and resulted in permanent disability.

Rectus femoris muscle flap donor-site morbidity.

Donor-site morbidity in four patients after reconstruction with free neurovascular rectus femoris muscle was examined through a series of strength tests in which the leg with rectus femoris muscle harvested was compared with the contralateral leg with an intact rectus femoris muscle. The tests were conducted with three testing devices: (1) the 'Con-Trex Leg-press' in which the force and power of right and left leg extensions at 0.2 and 0.4 m/s in a knee angle from 50 to 90 degrees were tested separately; (2) the isometric power tester, which enabled the unilateral evaluation of the isometric leg extension at three knee angles: 50, 70 and 90 degrees ; and (3) at the 'SP-Force Platforms' in which the patients performed a counter-movement jump where the amplitude of the ground reaction force, the parameters maximum force, and the jump height were calculated in order to compare the right and left leg during a single dynamic movement. Our results showed that the patients (with one exception) demonstrated a balanced relationship between the donor leg and the intact contralateral leg. The patient that primarily demonstrated a large strength deficit was retested 3 months later and showed, after an extensive rehabilitation and training program, an impressive increase in strength. The authors concluded that there is no significant limitation in the strength of the donor leg after removal of the rectus femoris muscle and consequently no significant functional donor-site morbidity. We believe that for the realisation of such results that the intraoperative linking of the vastus lateralis muscle with the vastus medialis muscle, especially in their lower third, and an extensive postoperative rehabilitation and training program are essential.

Quantitative assessment of periarticular osteopenia in patients with early rheumatoid arthritis: a preliminary report.

BACKGROUND: Involvement of the metacarpophalangeal (MP) joints is one of the major problems in patients with rheumatoid arthritis (RA). Although several data about the cumulative influence of steroid intake on bone are available, the course of demineralisation in RA has not been described by quantitative methods until now. PATIENTS AND METHODS: Computed tomography (CT) sections of 96 MP joints in 12 RA patients and of 32 MP joints in four age-matched healthy controls were investigated. Patients were classified according to Steinbrocker. Densitometric evaluation of subchondral bone density was performed by CT osteoabsorptiometry (CT-OAM). Quantitative CT-OAM was used to evaluate mineralisation of the articular surfaces in MP joints. RESULTS: In the distal articular surface of MP joints, the number of density maxima was reduced from 3 to 2.1+/-0.3, 1.9+/-0.5 and 1.3+/-0.3 in RA patients with early, mild to moderate, and severe disease, respectively. Means of calcium concentrations were 633.4+/-35. 3 mg Ca2+/mL, 518.9+/-56.2 mg Ca2+/mL, 497.7+/-23.8 mg Ca2+/mL and 455.1+/-28.6 mg Ca2+/mL for controls and RA patients with early, mild to moderate, and severe RA, respectively. Mineralisation of the distal articular surface was significantly reduced in all groups of RA patients [probability (p) = 0.005]. Regarding the number of density maxima, no differences were detected in the proximal articular surface of normal and RA fingers. However, mineralisation of the proximal articular surface was significantly reduced in all groups of RA patients (p = 0.004). Means of calcium concentrations of the proximal articular surface were 494.1+/-48.5 mg Ca2+/mL, 413.0+/-16.2 mg Ca2+/mL, 406.0+/-51.4 mg Ca2+/mL, 390,4+/-41.1 mg Ca2+/mL for controls and RA patients with early, mild to moderate, and severe RA, respectively. CONCLUSION: Patients with early and untreated RA show loss of mineralisation and altered morphology of the MP joints of the hand, even before corticosteroid therapy. CT-OAM provides evidence for an early alteration of functional anatomy in MP joints.

Anatomic survey of the common fibular nerve and its branching pattern with regard to the intermuscular septa of the leg.

Compression syndromes of the common fibular nerve and its branches frequently occur primarily as well as secondarily to trauma and surgery. A keen knowledge of the course and the relationship of the deep fibular nerve to adjacent anatomical structures in the proximal leg is mandatory. Previous literature often lacks detailed information on the course of the deep fibular nerve and is based on a limited number of observations. The aim of this study was to investigate the common fibular nerve and its branching pattern with special regard to the relationship between the deep fibular nerve and the anterior intermuscular septum of the leg. Variations in the course of the fibular nerve were demonstrated. The fibular compartments of the leg (n = 111) were dissected in 57 embalmed cadavers and included: 1) investigation of the number of muscular branches; 2) entering passages to the respective compartments of the leg; and 3) the relationship between the fibularis longus muscle and the deep fibular nerve. The most proximal muscular branch of the deep fibular nerve directly "pierced" the anterior intermuscular septum of the leg. Narrow passages within the fibular compartment and, in consequence, areas of possible higher incidence of nerve compression were suggested at the level of the intermuscular septa of the leg, between the two distinct portions of the fibularis longus muscle and the crossing of the supplying vessels. There were hardly ever statistically significant differences between the two sides or male and female gender. According to our results, the anterior intermuscular septum of the leg may be regarded as an important landmark for the surgeon when dissecting the muscular branches of the deep fibular nerve. The variable branching pattern of the deep fibular nerve within the fibular compartment of the leg should be taken into account.

Anatomical basis for a new island axial pattern flap in the perioral region.

Soft tissue defects of the perinasal and perioral regions usually result from trauma and tumor resection as well as from congenital diseases. Coverage of facial defects is frequently challenging. The goal of reconstruction is to achieve a functional and esthetically satisfactory result. The most common techniques of wound care, such as full-thickness skin grafts and primary wound closure, are not suitable in all cases and therefore transposition flaps become necessary. Despite the description of numerous flaps, the search for other reconstruction possibilities and the development of additional flaps with good color match and minimal donor site morbidity is continuing. The purpose of our study was to describe the course of the facial artery and the pattern of its branches, because clinical cases have shown that there are branches which are suitable for skin island flaps. During the anatomical dissection of 31 cadavers (62 hemifaces), we analyzed a cutaneous branch of the facial artery, which we named due to its topographical location the "cutaneous zygomatic branch". This vessel shows a highly constant origin and course, as well as a relatively wide area of supplied skin. Based on our anatomical observations, we suggest a new axial pattern skin island flap which awaits clinical application. We feel that this flap has great future potential.

Dupuytren's disease in children-differential diagnosis.

BACKGROUND/PURPOSE: Dupuytren's disease in children is uncommon; only a few histologically confirmed diagnoses are found in literature. In its early, proliferative phase with many fibroblasts, it can resemble the early stadium of an epitheloid sarcoma, which also is a rare tumor. The purpose of this report is to show pediatric surgeons and pathologists the importance of differential diagnosis of nodules and fibrotic bands in children's hands, especially to exclude a malignancy. METHODS: Between 1998 and 2000, 3 children at ages of 2(1/2) years, 9 years, and 10 years, respectively, presented with the clinical signs of Dupuytren's disease of the hand. Each of them had fibrous bands with a flexion contracture of the fingers. All of them underwent fasciectomy. RESULTS: In patient 1, a 10 degrees extension lag of the index finger resulted after 3 operations. Histology findings showed the typical features of Dupuytren's disease. In patient 2, histology findings showed a recurring digital fibroma of childhood. After consultation with the pathologist and reevaluation of the slides, the histologic diagnosis was corrected to Dupuytren's disease. Full extension and thumb abduction has been achieved. In patient 3, histology of the first and second operation was misdiagnosed as Dupuytren's disease. In the third operation 2(1/2) years later, the histologic diagnosis of epitheloid sarcoma was made. Amputation of the forearm was necessary. CONCLUSIONS: Exact anamnesis, location of the lesion, and suspicious diagnosis must be mentioned to the pathologist in the case of biopsy or excision of Dupuytrenlike lesions in children's hands. Awareness of the possibility of the epitheloid sarcoma may help prevent misdiagnosis.

Incidence of intraabdominal infection in a consecutive series of 40 enteric-drained pancreas transplants with FK506 and MMF immunosuppression.

Although the introduction of FK506 and MMF has markedly improved patient and graft outcome after pancreas transplantation, this procedure is still associated with a high surgical complication rate. The aim of the following study was to retrospectively analyze a series of 40 consecutive pancreas transplants with enteric drainage with regard to intraabdominal infection (IAI). Between March 1997 and December 1998 a total of 40 whole pancreas transplants were performed. Prophylactic immunosuppression consisted of an intraoperative single shot ATG (Thymoglobulin), FK506, MMF, and prednisone. The mean observation period was 14.6 (5-26) months. Overall incidence of IAI was 27.5% (n = 11) leading to pancreatectomy in 5 patients (12.5%). In the remaining 6 patients the graft could be rescued by necrosectomy and radical drainage of the abscess (5 patients) or percutaneous drainage (1 patient). Pancreatectomy or local infection did not alter kidney graft function in the 11 patients with simultaneous pancreas kidney transplantation. In 10 patients no evidence for leakage at the site of enteric anastomosis was present, one duodenal leak occurred due to ischemia. IAI in the early postoperative period was the predominat risk factor for graft loss. An early and invasive diagnostic approach is recommended to maximize the chance of graft rescue.
