A meta-analysis of acupuncture for chronic pain.

Results of 14 randomized controlled trials of acupuncture for chronic pain were pooled in a meta-analysis and analysed in three subgroups according to site of pain; and in two subgroups each according to type to trial, type of treatment, type of control, 'blindness' of participating agents, trial size, and type of journal in which results were published. While few individual trials had statistically significant results, pooled results of many subgroups attained statistical significance in favour of acupuncture. Various potential sources of bias, including problems with blindness, precluded a conclusive finding although most results apparently favoured acupuncture.

Risk Factors for Incisional and Organ Space Surgical Site Infections After Liver Resection are Different.

BACKGROUND: Surgical site infection (SSI) is a common cause of major morbidity after liver resection. This study aimed to identify the risk factors for incisional and organ/space SSIs after liver resection. METHODS: Our liver surgery database was retrospectively analyzed for patients treated between January 2009 and November 2012 in a tertiary care Swiss hospital. Univariate and multivariate analyses were conducted on preoperative, intraoperative, and postoperative variables to identify risk factors for incisional and organ/space SSIs. RESULTS: In a total of 226 patients, SSI incidences were 12.8 % (incisional), 4.0 % (organ/space), and 1.8 % (both). Univariate analysis showed that incisional SSIs were associated with high American Society of Anesthesiologists (ASA) scores, preoperative anemia, hypoalbuminemia, low prothrombin time, viral or alcoholic chronic hepatitis, liver cirrhosis, and prolonged operation times. Organ/space SSIs were associated with high rates of red blood cell transfusions, concomitant bowel surgery, and prolonged operation times. Multivariate analysis revealed that risk factors for incisional SSIs were anemia [odds ratio (OR) 2.82], high ASA scores (OR 2.88), presence of hepatitis or cirrhosis (OR 5.07), and prolonged operation times (OR 9.61). The only risk factor for organ/space SSIs was concomitant bowel surgery (OR 5.53). Hospital stays were similar in organ/space and incisional SSI groups, but significantly longer for those with both organ/space and incisional SSIs. CONCLUSIONS: High ASA scores, anemia, chronic hepatitis or liver cirrhosis, and prolonged operations increased the risk of incisional SSIs; concomitant bowel surgery increased the risk of organ/space SSI. Specific precautions to prevent organ/space and incisional SSIs may shorten hospital stays.

PTPN11 mutation manifesting as LEOPARD syndrome associated with hypertrophic plexi and neuropathic pain.

BACKGROUND: LEOPARD syndrome (LS) belongs to the family of neuro-cardio-facio-cutaneous syndromes, which include Neurofibromatosis-1 (NF1), Noonan syndrome, Costello Syndrome, cardio-facio-cutaneous syndrome, Noonan-like syndrome with loose anagen hair and Legius syndrome. These conditions are caused by mutations in genes encoding proteins involved in the RAS-MAPK cellular pathway. Clinical heterogeneity and phenotype overlaps across those different syndromes is already recognized. CASE PRESENTATION: We hereby report a heterozygous de novo mutation in the PTPN11 gene (c.1403C > T) manifesting with a clinical picture of LS during childhood, and later development of neuropathic pain with hypertrophic plexi, which are typically observed in NF1 but have not been reported in LS. CONCLUSION: LS caused by PTPN11 mutations may be associated with hypertrophic roots and plexi. Consequently, clinicians should be aware of the possible development of neuropathic pain and consider specific diagnostic work-up and management.

Réhabilitation améliorée après chirurgie--L'ere de la prise en charge optimale du patient chirurgical [Enhanced Recovery After Surgery--optimal management of the surgical patient].

Enhanced Recovery After Surgery (ERAS) is a multimodal, standardized and evidence-based perioperative care pathway. With ERAS, postoperative complications are significantly lowered, and, as a secondary effect, length of hospital stay and health cost are reduced. The patient recovers better and faster allowing to reduce in addition the workload of healthcare providers. Despite the hospital discharge occurs sooner, there is no increased charge of the outpatient care. ERAS can be safely applied to any patient by a tailored approach. The general practitioner plays an essential role in ERAS by assuring the continuity of the information and the follow-up of the patient.

A systematic review of the surgical treatment of large incisional hernia.

PURPOSE: Incisional hernia (IH) is one of the most frequent postoperative complications. Of all patients undergoing IH repair, a vast amount have a hernia which can be defined as a large incisional hernia (LIH). The aim of this study is to identify the preferred technique for LIH repair. METHODS: A systematic review of the literature was performed and studies describing patients with IH with a diameter of 10 cm or a surface of 100 cm2 or more were included. Recurrence hazards per year were calculated for all techniques using a generalized linear model. RESULTS: Fifty-five articles were included, containing 3,945 LIH repairs. Mesh reinforced techniques displayed better recurrence rates and hazards than techniques without mesh reinforcement. Of all the mesh techniques, sublay repair, sandwich technique with sublay mesh and aponeuroplasty with intraperitoneal mesh displayed the best results (recurrence rates of <3.6%, recurrence hazard <0.5% per year). Wound complications were frequent and most often seen after complex LIH repair. CONCLUSIONS: The use of mesh during LIH repair displayed the best recurrence rates and hazards. If possible mesh in sublay position should be used in cases of LIH repair.

Expert clinical reasoning and pain assessment in mechanically ventilated patients: A descriptive study.

BACKGROUND: Pain assessment in mechanically ventilated patients is challenging, because nurses need to decode pain behaviour, interpret pain scores, and make appropriate decisions. This clinical reasoning process is inherent to advanced nursing practice, but is poorly understood. A better understanding of this process could contribute to improved pain assessment and management. OBJECTIVE: This study aimed to describe the indicators that influence expert nurses' clinical reasoning when assessing pain in critically ill nonverbal patients. METHODS: This descriptive observational study was conducted in the adult intensive care unit (ICU) of a tertiary referral hospital in Western Switzerland. A purposive sample of expert nurses, caring for nonverbal ventilated patients who received sedation and analgesia, were invited to participate in the study. Data were collected in "real life" using recorded think-aloud combined with direct non-participant observation and brief interviews. Data were analysed using deductive and inductive content analyses using a theoretical framework related to clinical reasoning and pain. RESULTS: Seven expert nurses with an average of 7.85 (±3.1) years of critical care experience participated in the study. The patients had respiratory distress (n=2), cardiac arrest (n=2), sub-arachnoid bleeding (n=1), and multi-trauma (n=2). A total of 1344 quotes in five categories were identified. Patients' physiological stability was the principal indicator for making decision in relation to pain management. Results also showed that it is a permanent challenge for nurses to discriminate situations requiring sedation from situations requiring analgesia. Expert nurses mainly used working knowledge and patterns to anticipate and prevent pain. CONCLUSIONS: Patient's clinical condition is important for making decision about pain in critically ill nonverbal patients. The concept of pain cannot be assessed in isolation and its assessment should take the patient's clinical stability and sedation into account. Further research is warranted to confirm these results.

Place actuelle de la papillotomie chirurgicale transduodénale [Current status of surgical transduodenal papillotomy].

The treatment of biliary lithiasis has changed during the past 20 years. Cholecystectomy remains the gold standard for cholelithiasis, but many options are available for calculi of the common bile duct. Among them are surgical open or laparoscopic choledochotomy, biliary-enteric anastomosis, transduodenal sphincterotomy (TDS), endoscopic sphincterotomy. With the aim to describe the current place of TDS, we reviewed the patients operated on in our department between 1976 and 1992. We found 78 patients with a mean age of 58 years (26-89 years). 34 (43%) of them had acute cholecystitis, with 26 being operated on urgently. 47 (60%) were jaundiced, 15 (19%) had pancreatitis and 12 (15%) had cholangitis before operation. Indications for TDS have been impacted stone or absence of progression of the contrast medium on intraoperative cholangiography in 71 patients (91%). 3 patients died (1 pulmonary embolism, 1 sepsis of pulmonary origin, 1 MOF syndrome complicating preoperative necrotizing pancreatitis). 30 patients (38%) had complications, of which 20 were directly related to TDS. Hemorrhage occurred in 4 cases, and resolved spontaneously without transfusion. Hyperamylasemia occurred in 17 instances, but clinical pancreatitis developed in only 1 case, with complete resolution. 1 duodenal fistula healed after conservative therapy. No death is attributable directly to TDS. Today, the importance of endoscopic sphincterotomy is increasing. This retrospective study shows that TDS, if performed with caution, does not increase the operative risks even in emergent operations. During surgical exploration of the common bile duct, TDS is indicated to remove an impacted stone, or as a bilio-enteric anastomosis if multiple stones are present with a thin common duct.(ABSTRACT TRUNCATED AT 250 WORDS)

Surgical reconstruction of TMJ

Certain situations and pathological processes that arise with temporomandibular joint destruction can only be resolved with surgical reconstructive procedures in order to attempt a functional and anatomical rehabilitation of this joint. Many of these situations can be surgically treated with the patient's own autologous tissues. However, in some patients reconstruction is complex and the use of autologous tissues is unadvisable whereas reconstruction utilizing alloplastic materials may be an appropriate alternative. The following report describes 4 clinical cases in which autologous grafts or Christensen joint prosthesis are employed in temporomandibular joint reconstruction

Delayed presentation of deep penetrating trauma to the subaxial cervical spine.

PURPOSE: To present a rare case of deep penetrating neck trauma in which a retained foreign body in the cervical spine (a broken knife blade) resulted in delayed radicular injury. We describe the surgical management using a retrojugular approach. CASE REPORT: Our patient sustained a stab wound to the supraclavicular triangle from a small pocketknife. He was initially managed in a local hospital by simple primary wound closure without any radiological examinations, and was discharged home. The patient re-consulted in a delayed fashion with mild local persistent neck pain. Subsequent radiological investigations revealed a foreign body (the broken blade of a pocket knife) embedded in the left neural foramen between the C6 and C7 vertebrae penetrating the disc space. The blade was lying between the left C7 nerve root and the ipsilateral vertebral artery (VA) at the transition of V1 and V2 segments. Initial neurological evaluation was normal. Some days later, the patient developed a delayed left C7 radicular deficit. We undertook urgent exploration along the wound corridor through a retrojugular, transforaminal approach with successful removal of the blade. DISCUSSION: To our knowledge, this is a unique case where a retained foreign body penetrated the soft tissues of the neck, embedding deep in the vertebral column without vascular, aerodigestive or significant primary neurological injury, while causing delayed neck pain and delayed onset radicular injury. We describe our surgical management for removal of the retained blade. The retrojugular approach gives excellent access to all of the important anatomical structures of the neck from an anterolateral approach.

Gonalgies: que faire en médecine de premier recours [Knee pain in ambulatory practice].

Knee pain is a frequent complaint in ambulatory practice. Because of its complexity, the knee is prone to trauma, arthritis and the impact of aging. Septic arthritis is an emergency and has to be suspected when important knee pain is associated with fever, an alteration of the general condition, or in a particular social context. In most cases the clinical examination can identify the type of pathology. Conservative treatment is beneficial in most cases and physiotherapy a major component of the prognosis.

Benign fibro-osseous lesions of the maxillas: analysis of 11 cases

Introduction: A study is made of the principal characteristics of the oral lesions biopsied in our Service of Oral Surgery and histologically diagnosed as corresponding to fibro-osseous lesions of the maxillas. Patients and methods: A retrospective review was made of all the biopsies made in a Service of Oral Surgery between 1996 and 2003. The reason for consultation was analyzed, along with patient age, sex, clinical and radiological characteristics, tentative diagnosis, histological diagnosis and treatment provided. Results: A total of 1238 biopsies were performed during the study period. Of these, only 11 corresponded to benign fibro-osseous lesions (7 women and 4 men). The mean patient age was 44 years (range 19-72 years). The most frequent location was the mandible (8 of the cases). In 7 patients the lesions constituted casual radiological findings; 4 presented bulging of the vestibular cortical bone, though only one of them reported pain. The histological diagnoses comprised 7 cemento-ossifying fibromas and 4 fibrous dysplasias. In 9 cases surgical resection was carried out, while in one case an incisional biopsy was performed, and in the remaining case curettage was decided. Discussion: These lesions are more frequent in women than in men, and the age at presentation is variable. In terms of lesion location, fibrous dysplasia is more common in the upper maxilla, while cemento-ossifying fibroma is more frequently found in the mandible. The diagnosis of such lesions is established upon contrasting the data obtained from the anamnesis, physical examination, the radiological characteristics, the intraoperative findings and the histological study, since both disorders have similar clinical and histological features- despite the fact that they constitute distinct disease conditions.

Evaluation of the indication for surgical extraction of third molars according to the oral surgeon and the primary care dentist. Experience in the Master of Oral Surgery and Implantology at Barcelona University Dental School

Introduction: Third molar extraction is the most frequent procedure in oral surgery. The present study evaluates the indication of third molar extraction as established by the primary care dentist (PCD) and the oral surgeon, and compares the justification for extraction with the principal reason for patient consultation. Patients and method: A descriptive study was made of 319 patients subjected to surgical removal of a third molar in the context of the Master of Oral Surgery and Implantology (Barcelona University Dental School, Barcelona, Spain) between July 2004 and March 2005. The following parameters were evaluated: sex, age, molar, type of impaction, position according to the classifications of Pell and Gregory and of Winter, and the reasons justifying extraction. Results: The lower third molars were the most commonly extracted molars (73.7%). A total of 69.6% of the teeth were covered by soft tissues only. Fifty-six percent of the lower molars corresponded to Pell and Gregory Class IIB, while 42.1% were in the vertical position. The most common reason for patient reference to our Service of Oral Surgery on the part of the PCD was prophylactic removal (51.0% versus 46.1% in the case of the oral surgeon). Discussion and conclusions. Our results show prophylaxis to be the principal indication of third molar extraction, followed by orthodontic reasons. Regarding third molars with associated clinical symptoms or signs, infectious disease-including pericoronitis- was the pathology most often observed by the oral surgeon, followed by caries. This order of frequency was seen to invert in the case of third molars referred for extraction by the PCD. A vertical position predominated among the third molars with associated pathology

Phimose : Sind topische Kortikosteroide eine Alternative zur chirurgischen Behandlung [Phimosis : are topical corticosteroids an alternative to surgical treatment?]

Hintergrund: Die physiologische Phimose ist bereits bei der Geburt vorhanden und wächst sich in den meisten Fällen aus. Während 10% der Knaben im Alter von drei Jahren noch eine Phimose haben, nimmt diese Prävalenz auf 6-8% im Alter von sieben Jahren und 1% im Alter von 16 Jahren ab. Man spricht von einer pathologischen Phimose, wenn die Vorhaut Vernarbungen infolge von wiederholten Entzündungen oder forcierten Retraktionsversuchen aufweist. Dennoch ist die Unterscheidung zwischen pathologischer und physiologischer Phimose schwierig, und eine chirurgische Behandlung (Zirkumzision, Vorhautplastik) ist häufig. Eine topische Kortikosteroidbehandlung wird seit mehreren Jahren wegen seiner anti-inflammatorischen und immunsuppressiven Wirkung (Verminderung der Kollagenproduktion) angewendet. Es gibt aber keine Evidenz bezüglich Wirksamkeit und Sicherheit dieser Behandlung.

Survival after surgical drainage of malignant pericardial effusion.

OBJECTIVES: Management of malignant pericardial effusion (PE) is complex. Cardiac surgeons are not necessarily familiar with or are challenged by the many underlying etiologies. Analyzing risk factors for mortality may help to estimate the benefit of surgery in high-risk patients. METHODS: Patients undergoing a surgical pericardiotomy for malignant PE, between 2001 and 2011, were included. The influence of tumor type, disease extension, intra-pericardial tumor infiltration on early mortality and long-term survival as well as freedom from symptoms after drainage, and the use of sclerosing agents on PE recurrence rates was analyzed. RESULTS: PE drainage was performed on 46 patients 12 ± 30 months after tumor diagnosis. Malignant diseases were lung cancers (50 %), breast cancers (15 %), lymphoma and leukemia (13 %), cancers of the digestive tract (13 %), and others (9 %). 80 % of patients were symptomatic and symptom relief was achieved in 65 %. Nobody died during surgery. Recurrence rate was 4 %. Early in-hospital mortality was 22 %. After 1 year, 29 % of patients were alive. Eleven patients (24 %) had a complete tumor regression. Metastatic spread (p < 0.001), pericardial infiltration (p = 0.02), and intra-pericardial Bleomycin (p = 0.01) injection were associated with increased mortality. Hematological malignancies had a better prognosis for survival. CONCLUSION: Surgical pericardiotomy is safe, associated with a low recurrence rate and symptom relief in the majority of dyspneic patients. Intra-pericardial Bleomycin may reduce recurrent effusion but does not ameliorate survival. Long-term survival rate was low with an increased mortality in cases of metastatic spreading, pericardial infiltration, and as the tumor of origin: breast cancers. Leukemic and lymphatic tumors have better prognosis.
