The odors of the human vagina.

Gas-chromatography analysis of 90 samples of vaginal secretions from 10 women revealed that at any given sample time the perceptible vaginal odor of each individual women was composed of numerous separate odorous effluents. Almost 2,1000 odoriferous effluents were observed. This corresponded to 16% of all recorded peaks on the 90 gas-chromatograms. The odorous effluents were assigned 34 characteristic odors in three hedonic categories (neutral, pleasant and unpleasant). This information supports the contention that the olfactory signature of an individual is complex, highly individual and composed of many "mini odors".

Hypoglycemic coma associated with benign pleural mesothelioma.

A case of hypoglycemic coma and benign pleural mesothelioma is described. Serum insulin levels, as measured by insulin radioimmunoassay, were appropriately suppressed and consistent with hypoglycemia. Assay of the tumor showed insulin to be undectable. The mechanisms for hypoglycemia probably included increased glucose consumption by the tumor and, more important, the inhibition of lipolysis and hepatic gluconegenesis caused by tumor release of L-tryptophan and its metabolites and/or possibly nonsuppressible insulin-like activity, soluble in acid-ethanol(NSILA-s).

Placenta accreta and methotrexate therapy: three case reports.

Placenta accreta is a complication that is rising in incidence. The reported experience of methotrexate treatment in the conservative management of placenta accreta is scant. Three cases of placenta accreta managed with methotrexate are presented. Case 1: A woman had an antenatal diagnosis of placenta percreta. A successful manual placental removal occurred on post-cesarean day 16. Case 2: A woman had retention of a placenta accreta after a term vaginal delivery. Successful dilation and curettage were performed on postpartum day 37. Case 3: A woman had an antenatal diagnosis of placenta previa-percreta with bladder invasion. A simple hysterectomy was performed on post-cesarean day 46. Conservative management and methotrexate treatment resulted in uterine preservation in two of our three patients; however, this treatment did not prevent significant delayed hemorrhage. In view of the rapid resolution of vascular invasion of the bladder, methotrexate may have an important role in the management of placenta percreta with bladder invasion. The utility of methotrexate treatment with the conservative management of placenta accreta requires further evaluation.

Craniovertebral junction tuberculosis: a review of 29 cases.

PURPOSE: The purpose of this work was to describe the various imaging findings in craniovertebral tuberculosis and the importance of imaging in treatment in these patients. METHOD: A retrospective review of MR and CT scans in 29 patients with craniovertebral tuberculosis was performed. The images were reviewed, paying special attention to both bony (skull base, atlas, and axis) and soft tissue involvement in addition to atlantoaxial dislocation, lateral subluxation of the dens, and compression of the spinal cord. RESULTS: Suboccipital pain with neck stiffness was the most common presenting symptom in our patients. The skull was involved in 19 of the 29 cases, clivus involvement was seen in 11 patients, and occipital condyle involvement was present in 14 patients. Detailed analysis of atlas involvement due to tuberculosis showed the lateral masses to be predominantly affected. The dens was involved in 18 cases (62%). Soft tissue masses in the prevertebral area were seen in 22 patients, paravertebral in 27 patients, and epidural involvement in 25 patients was identified. Atlantoaxial displacement was present in seven cases, lateral mass-dens subluxation in five, and superior subluxation of the dens through the foramen magnum compressing the medulla was seen in two cases. Spinal cord compression with intrinsic cord changes was noted in 12 cases. All patients received multidrug antituberculous therapy for 1 year. The presence of neurologic deficit and instability of the atlantoaxial complex was pivotal in further management in these patients. CONCLUSION: A high degree of clinical suspicion is necessary when confronted with patients with neck stiffness and tenderness over the upper cervical vertebrae. MRI in these patients provides a sensitive method for the diagnosis of craniovertebral tuberculosis.

Safety and immunogenicity of intramuscular and intravaginal delivery of HIV-1 DNA constructs to infant chimpanzees.

Any global strategy for controlling the human immunodeficiency virus (HIV) epidemic is likely to rely heavily on immunization of infants and children. Given the well-documented differences in children's responses to traditional vaccines, we initiated this study to extend our findings on DNA vaccination of adult chimpanzees to immunologically immature infant chimpanzees. Our findings were consistent with our previous work in adults as we observed that the DNA vaccines used here were both well tolerated and immunogenic within weeks of the initial vaccination.

Pedunculated nasal glioma: MRI features and review of the literature.

Nasal gliomas are uncommon lesions, with approximately 100 cases reported in the literature. We present a case of intranasal glioma with a pedicle of glial tissue and defect in the cribriform plate of the ethmoid bone. Presence of such a pedicle is almost always present in the encephaloceles and is known to be distinctively uncommon in nasal gliomas.

Ruptured intracranial dermoids: magnetic resonance imaging.

Rupture of intracranial dermoids tumour is rare and carries with it the risk of significant morbidity as well as fatality. Three cases that presented with varying symptoms ranging from headache to chiasmatic compression and suspected to have rupture of dermoid tumour are described. The importance of MR imaging in their diagnosis is discussed.
