Gastrointestinal damage associated with the use of nonsteroidal antiinflammatory drugs.

BACKGROUND. Long-term use of nonsteroidal antiinflammatory drugs (NSAIDs) may lead to inflammation of the small intestine associated with occult blood and protein loss. The aim of this study was to investigate the prevalence and structural correlates of this enteropathy. METHODS. We examined the stomach, duodenum, and small intestine of 713 patients post mortem. Of these patients, 249 had had NSAIDs prescribed during the six months before death and 464 patients had not. All visible small intestinal lesions were removed for histologic examination, and specific etiologic factors were sought. The prevalence of nonspecific small-intestinal ulcers and ulcers of the stomach and duodenum was compared in the two groups of patients. RESULTS. Nonspecific small-intestinal ulceration was found in 21 (8.4 percent) of the users of NSAIDs and 3 (0.6 percent) of the nonusers (difference, 7.8 percent; 95 percent confidence interval, 5.0 to 10.6 percent; P less than 0.001). Three patients who were long-term users of NSAIDs were found to have died of perforated nonspecific small-intestinal ulcers. Ulcers of the stomach or duodenum were found in 54 (21.7 percent) of the patients who used these drugs and 57 (12.3 percent) of those who had not (difference, 9.4 percent; 95 percent confidence interval, 3.9 to 15.1 percent; P less than 0.001). CONCLUSIONS. Patients who take NSAIDs have an increased risk of nonspecific ulceration of the small-intestinal mucosa. These ulcers are less common than ulcers of the stomach or duodenum, but can lead to life-threatening complications.     

Reconstruction of a functional and esthetic nail

The most common cause of nail bed deformity is trauma, but other causes are infection, tumor, ischemia, or congenital anomalies. This article includes discussions of nonadherence, split nail, reconstruction of the eponychium, crooked and hooked nail, bony irregularity, pachyonychia, ischemic deformities, and absence of the nail. New problems are encountered daily and other deformities have no method of correction recorded in the literature. For these cases, we provide suggested treatments based on the anatomy and physiology of the nail.     

Unannounced simulated patients' observations of physician STD/HIV prevention practices.

Studies describing sexually transmitted disease (STD) and human immunodeficiency virus (HIV) prevention practices of primary care physicians have relied on physician or patient reports. This study describes physician STD/HIV prevention practices as observed by unannounced simulated patient evaluators (SPEs). SPEs visited sixty-five primary care physicians. Each SPE portrayed a sexually active female, new to the area, requesting a consultation on STD prevention. One-third of the physicians in the study asked no risk questions, and over 80% failed to ask the SPE specifically about her sexual practices. Most physicians discussed the risks of STDs and HIV and covered basic recommendations (use condoms and know partners better); however, few physicians provided any individualized information or advice about safer sexual practices and the specifics of condom use, such as how to use them or what kind to use. These observations support the low rates of STD/HIV prevention indicated in physicians' self-report and further identify specific deficiencies in the thoroughness of their risk assessment and preventive counseling practices.     

How competent are obstetric and gynaecology trainees in managing maternal cardiac arrests?

The recent Confidential Enquiry (2000-2002) has emphasised 'emergency drills for maternal resuscitation should be regularly practised in clinical areas in all maternity units'. It was therefore planned to assess the knowledge of airway management and ventilation among obstetrics and gynaecology trainees in the Yorkshire Deanery (Training Region). Questionnaires were given to trainees attending the Modular Training Programme and were collected on the same day. A total of 71 questionnaires were collected which represents 62% of the 113 trainees in Yorkshire region. Replies were received from 39 registrars, 27 Senior House Officers (SHO), four Senior SHOs (SSHO) and one clinical fellow. MRCOG Part 1 was passed by 52% and 36% of trainees had MRCOG Part 2. A total of 69% of trainees did not know that chin lift opens the airway in some 70 - 80% of patients; 50% of trainees were not aware why jaw thrust is preferred over chin lift; 76% of the trainees knew the most common cause of airway obstruction in a patient with an altered level of consciousness--the tongue falls back and obstructs the pharynx ('swallowing the tongue'). Knowledge of the main cause of airway obstruction was good among obstetrics and gynaecology trainees, but their understanding of how to manage this was found to be relatively poor. Attendance at a local Basic Life Support course should be compulsory for obstetric and gynaecology trainees early in their career.     

Type IV flexor digitorum profundus avulsion

Flexor digitorum profundus avulsions, are well-documented injuries occasionally associated with a distal phalanx fragment. While the injury may involve primarily either tendon or bone, a rarely observed variant combines both tendon and bone avulsions. A type IV variant seen after two sequential injuries is described.     

Dose fractionation of radiolabeled antibodies in patients with metastatic colon cancer.

Twelve patients with metastatic colon cancer were treated with 131I-chimeric B72.3 (IgG-4) at total doses of 28 or 36 mCi/m2 in two or three weekly fractions. Bone marrow suppression was the only significant side effect. The degree of bone marrow suppression adjusted for whole-body dose was modestly but statistically significantly (p = 0.04) less than that seen with identical doses given as a single infusion for the total dose of 36 mCi/m2. Nine of twelve patients developed an antibody response to ch B72.3, which altered the kinetics of radiolabeled antibody in four patients given a second course of therapy. One patient had a minor response that lasted 4 mo. Fractionation of this particular radiolabeled antibody at the dose schedule used produced a modest increase in the therapeutic window in regard to administered dose.     

Ureteral obstruction following aortobifemoral bypass: management by endoscopic balloon dilation.

A 71-year-old man presented with left hydronephrosis 1 year after aortofemoral bypass. Hydronephrosis was due to extrinsic compression of the ureter between the graft anteriorly and the native iliac artery. Treatment by endoscopic transluminal balloon dilation resulted in complete resolution of the hydronephrosis.
