The Dome Technique for Managing Massive Anterosuperior Medial Acetabular Bone Loss in Revision Total Hip Arthroplasty: Short-Term Outcomes.

Purpose: The dome technique is a technique used in performance of revision total hip arthroplasty (THA) involving intraoperative joining of two porous metal acetabular augments to fill a massive anterosuperior medial acetabular bone defect. While excellent outcomes were achieved using this surgical technique in a series of three cases, short-term results have not been reported. We hypothesized that excellent short-term clinical and patient reported outcomes could be achieved with use of the dome technique.

Results: The objective response rate was 26% (95% confidence interval [CI], 18.

Multinational Study of the Efficacy and Safety of Humanized Anti-HER2 Monoclonal Antibody in Women Who Have HER2-Overexpressing Metastatic Breast Cancer That Has Progressed After Chemotherapy for Metastatic Disease.

Purpose: Overexpression of the HER2 protein occurs in 25% to 30% of human breast cancers and leads to a particularly aggressive form of the disease. Efficacy and safety of recombinant humanized anti-HER2 monoclonal antibody as a single agent was evaluated in women with HER2-overexpressing metastatic breast cancer that had progressed after chemotherapy for metastatic disease.

Patients And Methods: Two hundred twenty-two women, with HER2-overexpressing metastatic breast cancer that had progressed after one or two chemotherapy regimens, were enrolled.

Computer Navigation for Revision Total Hip Arthroplasty Reduces Dislocation Rates.

Purpose: Computer navigation in total hip arthroplasty (THA) offers potential for more accurate placement of acetabular components, avoiding impingement, edge loading, and dislocation, all of which can necessitate revision THA (rTHA). Therefore, the use of computer navigation may be particularly beneficial in patients undergoing rTHA. The purpose of this study was to determine if the use of computer-assisted hip navigation reduces the rate of dislocation in patients undergoing rTHA.

The impact of obesity in cirrhotic patients with septic shock: A retrospective cohort study.

Background & Aims: The prevalence of obesity in cirrhosis is rising. The impact of obesity in critically ill cirrhotic patients with sepsis/septic shock has not been evaluated. This study aimed to examine the relationship between obesity and mortality in cirrhotic patients admitted to the intensive care unit with septic shock.

Neuroendocrine Tumors of the Breast.

Primary neuroendocrine tumors of the breast are a rare and underrecognized subtype of mammary carcinoma. Neuroendocrine tumors of the breast occur predominately in postmenopausal women. The tumors are subclassified into well-differentiated and poorly differentiated neuroendocrine tumors, and invasive breast carcinoma with neuroendocrine features.

Intellijoint HIP: a 3D mini-optical navigation tool for improving intraoperative accuracy during total hip arthroplasty.

Total hip arthroplasty is an increasingly common procedure used to address degenerative changes in the hip joint due to osteoarthritis. Although generally associated with good results, among the challenges associated with hip arthroplasty are accurate measurement of biomechanical parameters such as leg length, offset, and cup position, discrepancies of which can lead to significant long-term consequences such as pain, instability, neurological deficits, dislocation, and revision surgery, as well as patient dissatisfaction and, increasingly, litigation. Current methods of managing these parameters are limited, with manual methods such as outriggers or calipers being used to monitor leg length; however, these are susceptible to small intraoperative changes in patient position and are therefore inaccurate.

Breath Methane Levels Are Increased Among Patients with Diverticulosis.

Background: Diverticulosis and its complications are important healthcare problems in the USA and throughout the Western world. While mechanisms as to how diverticulosis occurs have partially been explored, few studies examined the relationship between colonic gases such as methane and diverticulosis in humans.

Aim: This study aimed to demonstrate a significant relationship between methanogenic Archaea and development of diverticulosis.

Prominent coronary artery flow with normal coronary artery anatomy is a rare but ominous harbinger of poor outcome in the fetus.

Objectives: "Heart sparing" refers to prominent antegrade fetal coronary artery (CA) blood flow readily visualized by color Doppler and is a harbinger of poor outcome in growth restricted fetus, but little is known of the features and presentation of heart sparing in normally grown fetuses. Our objective was to describe heart sparing effects in normally grown fetuses, and compare the presentation and outcome of heart sparing between fetuses with growth restriction and those who were normally grown.

Methods: In a series of fetuses with prominent antegrade CA flow, we assessed Doppler flow profiles in the aortic isthmus, ductus venosus (DV), umbilical vein (UV), umbilical artery (UA) and middle cerebral artery (MCA).

Genetic variant predicts bevacizumab-induced hypertension in ECOG-5103 and ECOG-2100.

Background: Bevacizumab has broad anti-tumour activity, but substantial risk of hypertension. No reliable markers are available for predicting bevacizumab-induced hypertension.

Methods: A genome-wide association study (GWAS) was performed in the phase III bevacizumab-based adjuvant breast cancer trial, ECOG-5103, to evaluate for an association between genotypes and hypertension.

A Phase II evaluation of ixabepilone (IND #59699, NSC #710428) in the treatment of recurrent or persistent leiomyosarcoma of the uterus: an NRG Oncology/Gynecologic Oncology Group Study.

Objective: The combination of gemcitabine and docetaxel is the standard first-line therapy for recurrent or metastatic uterine leiomyosarcoma. There is no standard second-line therapy. Ixabepilone is a semi-synthetic analog of epothilone B that binds to the same site on beta tubulin as paclitaxel and may be a more potent polymerizer of tubulin.

Intense pulsed light therapy.

Intense Pulsed Light (IPL) is an FDA-approved photo therapy for the treatment of a variety of conditions such as acne and hirsutism. It utilizes the principle of selective photothermolysis. Photothermolysis allows a specific wavelength to be delivered to a chromophore of a designated tissue while leaving the surrounding tissue unaffected.

Initiation of inappropriate antimicrobial therapy results in a fivefold reduction of survival in human septic shock.

Objective: Our goal was to determine the impact of the initiation of inappropriate antimicrobial therapy on survival to hospital discharge of patients with septic shock.

Methods: The appropriateness of initial antimicrobial therapy, the clinical infection site, and relevant pathogens were retrospectively determined for 5,715 patients with septic shock in three countries.

Results: Therapy with appropriate antimicrobial agents was initiated in 80.

Newer anesthesia and rehabilitation protocols enable outpatient hip replacement in selected patients.

Unlabelled: Advancements in the surgical approach, anesthetic technique, and the initiation of rapid rehabilitation protocols have decreased the duration of hospitalization and subsequent length of recovery following elective total hip arthroplasty. We assessed the feasibility and safety of outpatient total hip arthroplasty in 150 consecutive patients. A comprehensive perioperative anesthesia and rehabilitation protocol including preoperative teaching, regional anesthesia, and preemptive oral analgesia and antiemetic therapy was implemented around a minimally invasive surgical technique.

The feasibility and perioperative complications of outpatient knee arthroplasty.

Unlabelled: The duration of hospitalization and subsequent length of recovery after elective knee arthroplasty have decreased. We hypothesized same-day discharge following either a unicompartmental (UKA) or total knee arthroplasty (TKA) in an unselected group of patients would not result in a higher perioperative complication rate than standard-length hospitalization when following a comprehensive perioperative clinical pathway, including preoperative teaching, regional anesthesia, preemptive oral analgesia, preemptive antiemetics, and a rapid rehabilitation protocol. We prospectively followed 111 of all 121 patients who had primary knee arthroplasty completed by noon and who agreed to be followed prospectively; 25 had UKA and 86 TKA.

Outcome of arthroscopic repair of type II SLAP lesions in worker's compensation patients.

Purpose: Arthroscopic stabilization has become the accepted treatment for type II superior labral anterior and posterior (SLAP) lesions. Short-term results using a variety of techniques were promising, but most reports focus on motivated athletes. The purpose of our report is to evaluate the results of arthroscopic fixation of type II SLAP lesions in 21 patients who suffered a work-related injury and are receiving workers' compensation.

Impaired compensation for mechanical loads in a patient with hemiballismus following stroke.

Flexion movements of the wrist were studied in a patient who showed signs of hemiballismus following a unilateral infarction, which damaged the region neighboring the subthalamic nucleus. The experiments were designed to test whether a lesion of this nature impairs load compensation and, specifically, whether antagonist activity can be appropriately suppressed when initiating a movement. The latency between movement onset and agonist EMG onset changed from the normal relationship where agonist onset precedes movement to one where agonist onset followed movement when an extensor load was placed on the affected limb.

Epidural cylinder electrodes for presurgical evaluation of intractable epilepsy: technical note.

Background: This is a technical report describing a different technique for the insertion of epidural electrodes in the preoperative evaluation of epilepsy surgery. Our experience in 67 cases using this technique is analyzed.

Methods: Cylinder electrodes with multiple recording nodes spaced 1 cm apart along a Silastic core are placed into the epidural space under general anesthesia through single or multiple burr holes.

Preoperative considerations and creation of normal ostomies.

Stomas provide fecal diversion in emergent and elective settings. Preoperative planning and counseling are extremely important to the creation of an acceptable and functional ostomy for the surgeon and patient. Proper site selection will help decrease the incidence of postoperative complications.

Long-term Outcome of Adult Onset Idiopathic Minimal Change Disease.

Minimal Change Disease (MCD) is the lesion most commonly associated with nephrotic syndrome in children, accounting for over 75% of cases. Although less common, MCD still accounts for up to 30% of adult onset nephrotic syndrome. Unlike children, in whom MCD is primarily idiopathic, secondary causes of MCD are seen in 13% of adults and must be considered, as the therapeutic approach to these patients is defined by the underlying cause.
