Lipid profile studies in inner ear dysfunction

In the present paper fifty patients with symptoms of inner ear dysfunction, primarily deafness, vertigo or both, were subjected to a detailed history, pure tone audiometry and caloric tests. A detailed serum lipid analysis was done of all the patients. It was concluded that atherosclerotic disease of the labyrinthine vessels usually affects patients above forty years of age. It occurs bilaterally. Commonly both the cochlear and vestibular components are involved. Raised serum total cholesterol, L.D.L. cholesterol levels and hypertension, are more contributory as risk factors in its development.     

Provider attitudes regarding use of an immunization information system to identify children with asthma for influenza vaccination.

OBJECTIVES: Despite longstanding national guidelines, many children with asthma do not receive annual influenza vaccinations. Information from Medicaid-administrative claims data was integrated into the Michigan Care Improvement Registry (MCIR) to prompt providers regarding influenza vaccination among children with high-risk conditions such as asthma. The attitudes of pediatric primary care providers regarding the implementation of this system were assessed. METHODS: A survey was sent in February 2006 to office-based general pediatricians (n = 300) and family physicians (n = 300) in Michigan. The survey focused on influenza vaccination during the 2005-2006 influenza season and attitudes regarding a reminder system for providers using the MCIR. RESULTS: Overall response rate was 67 percent. MCIR participation was high (91%) among respondents, and most (83%) had MCIR information available to them prior to visits with pediatric patients. Most physicians (75%) considered the MCIR high-risk indicator for influenza vaccination a feature that they would find helpful. Some respondents reported concerns that the reminder system is limited to Medicaid patients only (44%) and regarding the completeness of Medicaid data to identify children with asthma (24%). CONCLUSIONS: Physicians have a positive overall view of a statewide registry-based automated reminder system to assist in identifying children with asthma for influenza vaccination, albeit with specific areas of concern.     

Measurement of capillary filtration coefficient in a solid tumor

The net transvascular filtration rate, JF (ml/min/100 g), in an isolated, RBC-free perfused R3230AC mammary adenocarcinoma tumor was measured using a gravimetric method whereby changes in tissue weight over time were monitored. From the gravimetric measurements of JF following changes in venous pressure, the capillary filtration coefficient (ml/min/mm Hg/100 g) was found to be 2.2 (range, 0.8-2.8), i.e., 10 to 1000 times higher than those found in several normal tissues and within the range of those reported for glomerular capillaries. These measurements of capillary filtration coefficient are consistent with elevated tumor interstitial fluid pressure, interstitial fluid flow, and peritumor edema.     

Corpectomy for multi-level cervical spondylosis and ossification of the posterior longitudinal ligament

The choice of a surgical approach for multi-level cervical spondylotic myelopathy (CSM) and ossification of the posterior longitudinal ligament (OPLL) is still a controversial issue. While most of the surgeons are still performing decompression by laminectomy some are doing multi-level anterior decompression. Few neurosurgeons are performing decompression by corpectomy. We have treated 26 patients by median cervical corpectomy during the last 4 years. These patients were followed up for a mean period of 25 months. Twenty one (80%) patients had a good outcome, 2 patients remained unchanged and 3 expired. Review of the literature and our experience indicates that patients with CSM and OPLL should be operated by median cervical corpectomy (anterior approach).     

Insulin dependent diabetes in children

We present our experience with twenty children with insulin dependent diabetes mellitus admitted during the past 2 1/2 years. Sixteen patients were admited with acute onset of ketoacidosis while four were having gradual onset. Active and symptomatic treatment was started in all diabetic ketoacidotic patients. One patient died during the acute stage. Eleven patients were followed for 3–6 months or more. Glycosylated hemoglobin was considered as a criteria for control. Three had good control, two fair and six poor control; six developed diabetic ketoacidosis and three developed hypoglycemia
