An Uncommon Coexistence of Dural and Intraventricular Meningiomas.

Meningiomas, originating from the meninges encasing the brain and spinal cord, are the most prevalent primary intracranial tumors, constituting around 40% of all such tumors. These tumors primarily manifest within the dura mater, the outermost meningeal layer, and occasionally in locations such as the ventricular system. However, the concurrent presence of dural and intraventricular meningiomas is exceedingly rare.

Isolation, screening, characterization, and optimization of bacteria isolated from calcareous soils for siderophore production.

The most effective agricultural practice to prevent iron deficiency in calcareous soils is fertilizing with synthetic chelates. These compounds are non-biodegradable, and persistent in the environment; hence, there is a risk of leaching metals into the soil horizon. To tackle iron deficiency-induced chlorosis (IDC) in crops grown on calcareous soils, environmentally friendly solutions are needed rather than chemical application as it affects the soil health further.

Bilateral upper-lobe cavitary Pneumocystis carinii pneumonia in a patient on dapsone prophylaxis.

Pneumocystis carinii pneumonia (PCP) presenting as bilateral upper-lobe cavitary disease is rare. Isolated upper-lobe involvement has traditionally been associated with aerosolized pentamidine prophylaxis. Dapsone is a cheap and effective prophylactic agent against P carinii in patients who cannot tolerate trimethoprim-sulfamethoxazole.

Primary biphasic synovial sarcoma of the pleura.

Synovial sarcoma most commonly occurs in the peri-articular regions of the extremities. The present report describes a rare case of primary biphasic synovial sarcoma of the pleura in an 18-year-old female. The diagnosis was made on the basis of light microscopy, immunohistochemistry, electron microscopy and the characteristic translocation found on cytogenetic analysis.

Cocaine-associated intestinal gangrene in a pregnant woman.

A 31-year-old pregnant woman who was an active cocaine abuser presented to our emergency department five times in 1 week for abdominal pain and vomiting. She continued to use cocaine regularly despite having abdominal pain. Her fifth admission was for seizures.

Pulse oximetry in the evaluation of peripheral vascular disease.

The role of pulse oximetry in the evaluation of peripheral vascular disease (PVD) was investigated. In addition, the value of elevating the limb to improve the sensitivity of detection of PVD by the pulse oximeter was also determined. Pulse oximetry reading in the toes were obtained in 40 young, healthy volunteers and in 40 randomly selected patients referred to the vascular investigation laboratory over a period of two months.
