An update on advances in interventional bronchoscopy

Abstract: Because of recent advances, more patients may potentially benefit from a variety of interventional bronchoscopic techniques. Nd:YAG laser phototherapy is the most widely used modality and is the treatment of choice for patients with endobronchial malignancies who have large-central airway obstruction. Cryotherapy may be superior to Nd:YAG phototherapy for more distal airways lesions because of the lower risk of airway perforation, but it may be suboptimal for bulky airways disease that requires quick relief of obstruction. Brachytherapy relieves symptoms, such as cough, dyspnea, and hemoptysis, in many patients who have locally invasive airway malignancies. Endobronchial ultrasonography appears to be a safe and sensitive method for staging lung cancer. In select patients with emphysema, a 1-way endobronchial valve can be used to reduce lung volumes. Bronchial thermoplasty is being studied as a potential treatment for asthma. (J Respir Dis. 2006;27(10):415-428)

Cutaneous Metastasis of Prostatic Adenocarcinoma

This lesion had appeared in the right groin of a 60-year old man and had slowly enlarged over a month (A). Two years before this evaluation, he had undergone total prostatectomy with lymph node dissection for prostate carcinoma. Metastatic disease was found in a resected lymph node, and he underwent multiagent chemotherapy.

New Treatments for Early and Late COPD: Part 1, Prevention

ABSTRACT: The key factor in reducing morbidityand mortality in patients with chronicobstructive pulmonary disease (COPD)continues to be smoking cessation. Newerformulations of nicotine replacementtherapy-a nasal spray and an inhaler-provide rapid delivery of nicotine and maybe appropriate for highly dependent smokers.Bupropion has been shown to improvesmoking cessation rates, either when usedalone or with a nicotine patch. Both theinfluenza and pneumococcal vaccines arerecommended to reduce the morbidity andmortality associated with respiratory infectionsin patients with COPD.

COPD: How to Manage Early and Late Disease

The goals of therapy in chronic obstructive pulmonary disease are to ameliorate symptoms, improve daily function, preserve lung function, identify and reduce exacerbations and, if possible, decrease mortality. A comprehensiveapproach that includes prevention, early identification, and pharmacotherapy-and oxygen therapy, pulmonary rehabilitation, and/or surgery when appropriate-can optimize patient outcomes.

Paralytic Ileus

This obstruction is caused by a failure of intestinal peristalsis; there is no evidence of mechanical obstruction. Paralytic ileus is common after abdominal surgery, especially if anticholinergic drugs are given preoperatively and/or narcotics are used postoperatively. It usually lasts 2 to 3 days. Paralytic ileus may also be caused by peritonitis; ischemia or surgical manipulation of the bowel; retroperitoneal hemorrhage; spinal fracture; systemic sepsis; shock; hypokalemia; uremia; pharmacologic agents (eg, vincristine, loperamide, and calcium channel blockers); diabetic ketoacidosis; and myxedema.

Share the Burden of Uncertainty With Patients

Renal Infarction: An Unusual Complication of Cocaine Abuse

What You Forgot About the Neurologic Exam, Part 2:

ABSTRACT: Asymmetry-whether of strength, reflexes, or sensory function-is an important localizing finding in the neurologic evaluation. Asymmetric deficits of strength may indicate an acute CNS lesion. Symmetric hyperreflexia or hyporeflexia alone is not diagnostic; compare reflexes between sides of the body and between upper and lower extremities. The extensor plantar response (Babinski reflex) suggests an upper motor neuron lesion. During the sensory examination, look for asymmetry and determine whether both light touch and pinprick sensation are intact. Simultaneous stimulation with 2 sharp objects on opposite sides of the body-done to detect extinction of response on 1 side-can uncover subtle sensory deficits.

Chronic Diarrhea:

Chronic diarrhea presents difficulties for clinicians as well as for patients. Because the differential diagnosis is enormous, management can be challenging. In this article, we present a strategy for quickly narrowing the differential based on a simple analysis of stool characteristics. We then describe an appropriate workup for each of the basic types of diarrhea.

Orbital Pseudotumor Disguised as Orbital Cellulitis and Sinusitis

A 58-year-old man with a past medical history of chronic sinus disease and hypothyroidism presented with left periorbital pain and erythema that worsened despite outpatient treatment with topical antibiotics. An outpatient CT scan showed pansinusitis and orbital stranding. The diagnosis was orbital cellulitis and sinusitis.

Chronic Tophaceous Gout

These joint deformities occurred in a 61-year-old man with chronic tophaceous gout. The patient had had joint pain and swelling since he was 40 years old; the symptoms began in 2 fingers and were initially mild. He did not seek medical attention. Within 5 to 10 years, joint abnormalities had developed in the fingers and then in the left elbow and right ankle. The toes were not affected. He had no family history of joint pain or swelling. Serum uric acid level was 9.7 mg/dL.

Emerging Strategies in HIV Prevention

HIV infection continues to exact a devastating toll worldwide.Advances in antiretroviral therapy have helped bring theHIV/AIDS epidemic under control in developed countries.Antiretroviral drugs, however, are not widely available inthose developing countries where HIV poses a catastrophicthreat. Effective strategies for HIV prevention are thereforecrucial to curbing the global epidemic. Vaccination, microbicideuse, and male circumcision are 3 key preventive interventions.Current research is focused on developing effective vaccinesand microbicides and on determining the extent to whichcircumcision helps prevent HIV acquisition and transmission.[Infect Med. 2008;25:63-72]
