Florid cutaneous papillomatosis with adenocarcinoma of stomach in a 35 year old male

Various paraneoplastic dermatoses may be seen in association with underlying visceral, especially gastrointestinal, malignancy. Florid cutaneous papillomatosis describes the sudden appearance of multiple acuminate keratotic papules that morphologically resemble viral warts. It may be seen in association with acanthosis nigricans and/or the sign of Leser Triotalat. We report a 35-year-old male with extensive seborrhoeic keratoses and florid cutaneous papillomatosis. Unusually marked verrucous changes caused disfigurement of the hands and feet. The patient also reported dyspepsia, abdominal distention and weight loss 6 months prior to the development of cutaneous lesions. Gastroscopy revealed a large growth in the stomach. Histopathology of the tumor showed features of adenocarcinoma.     

Myocardial contusion injury: redefining the diagnostic algorithm

Myocardial contusion injury (MCI) is a complication of blunt thoracic trauma, which may occur at relatively low velocities. MCI may also occur from chest compressions during cardiopulmonary resuscitation. We review the clinical pathology, diagnostic tools, and treatment for MCI.     

Disorders of flushing

Disorders of flushing encompass a broad spectrum of diverse acquired and inherited conditions. Chemical mediators involved in the flushing response are incompletely understood. Flushing episodes rarely can be associated with significant morbidity and mortality. The goal of the physician is to separate benign from potentially life-threatening conditions. Accurate diagnosis requires a thorough history and physical examination emphasizing the age of the patient, temporal association of flushing with occupation, environmental, stress, food, or drug exposure, and the duration of the episode. In some cases, despite a thorough evaluation, the etiology for flushing remains unknown. Understanding the distinct mechanisms that lead to flushing helps provide a rational approach to treatment.

Inferior vena cava filter removal after 317-day implantation

A Günther Tulip inferior vena cava (IVC) filter was placed prophylactically in a 22-year-old trauma victim with spinal injuries. Attempts to retrieve the filter at 21 and 25 days after placement were aborted as a result of clot trapped in the filter. Despite the possible risk of an IVC laceration, a third attempt was made 317 days after placement in view of the young age of the patient. The filter started collapsing into the retrieval sheath but could not easily be separated from the IVC. During attempted redeployment, the filter would not reopen. The filter was ultimately retrieved with use of additional force. A mild stenosis of the IVC was noted immediately after retrieval. However, the IVC returned to its preretrieval diameter as seen on a 3-month follow-up venogram.     

One liver, three recipients: segment IV from split-liver procedures as a source of hepatocytes for cell transplantation

Hepatocyte transplantation is emerging as a possible treatment for patients with acute liver failure and liver-based metabolic disorders. With the limited availability of donor tissue, it is important to find new sources of liver tissue for isolation of high-quality hepatocytes. Segment IV with or without the caudate lobe was removed during three split-liver procedures. Hepatocytes were isolated from the tissues using a collagenase perfusion technique under strict sterile conditions. The mean number of hepatocytes that were isolated was 5.14 x 10(8) cells with a mean cell viability of 89%. Two of the hepatocyte preparations were used for cell transplantation in a 1-day-old boy with an antenatal diagnosis of a severe urea cycle defect caused by ornithine transcarbamylase deficiency. The six recipients of split-liver grafts demonstrated no complications related to the removal of segment IV. Segment IV with or without the caudate lobe obtained from split-liver procedures is potentially a good source of high-quality hepatocytes for cell transplantation.     

Serum cortisol levels in children with acute bacterial and aseptic meningitis.

OBJECTIVE: To study serum cortisol levels in acute childhood meningitis with respect to the severity of illness and the outcome. DESIGN: Prospective observational study. SETTING: Pediatric services of a tertiary care teaching and referral hospital. SUBJECTS: A total of 30 consecutive children, 2 months to 12 yrs of age, with suspected bacterial meningitis. METHODS: Serum cortisol levels (by enzyme-linked immunosorbent assay) obtained at admission were correlated with clinical characteristics (including Glasgow Coma Scale and Pediatric Risk of Mortality scores) recorded at admission and with neurologic and hearing status 2 months after discharge using SPSS 10.0. RESULTS: Mean +/- sd serum cortisol was 467 +/- 251 ng/dL in patients with bacterial (n = 16) and 319 +/- 159 ng/dL in aseptic meningitis (n = 14, p = .068). Glasgow coma scale score, systolic blood pressure, age, Pediatric Risk of Mortality, and cerebrospinal fluid protein were significant independent predictors of serum cortisol on stepwise multivariate regression analysis (each had an R change of >5%). Patients with neurologic or hearing sequelae had significantly higher median serum cortisol (450 ng/mL, n = 12) than those without sequelae (300 ng/mL, n = 17; p = .043 by Mann-Whitney U test). On multivariate logistic regression analysis, a serum cortisol of >/=420 ng/mL (odds ratio, 0.022; 95% confidence interval, 0.01-0.43) and systolic blood pressure (odds ratio, 1.35; 95% confidence interval, 1.04-1.74) were significant independent predictors of neurologic and hearing sequelae. CONCLUSION: Low serum cortisol is uncommon in acute bacterial meningitis of nonmeningococcal pathogenesis. Very high levels are likely to be associated with sequelae.
