Paraspinal Abscess Secondary to Tuberculous Spondylitis Diagnosed by Xpert MTB/RIF Assay in Rural Tanzania.
A 31-year-old HIV-negative man presented to our clinic with a 6-month history of back pain and a swelling at the back. Radiological studies revealed lumbar vertebral destruction. Ultrasound of the mass showed a septated cystic mass with turbid fluid. Diagnostic aspiration revealed thick pus and smear microscopy detected acid-fast bacilli. Xpert MTB/RIF assay detected Mycobacterium tuberculosis with no rifampicin resistance
Stabilizing rational speculation and price level targeting
We analyze the contribution of speculation to exchange rate volatility using different assumptions regarding speculation strategies and monetary policy rules. We take the DORNBUSCH (1976) model as the starting point and adopt a slight modification of the money demand specification. With a money supply rule, rational speculation dampens the overshooting of the exchange rate following a money supply shock, compared with speculation based on static expectations. Then, we replace the LM condition by a TAYLORtype price level targeting rule rule. The resulting 'DORNBUSCH-TAYLOR' model generates a unique saddle point solution even under 'strict' inflation targeting, if speculation is based on rational expectations. Under 'flexible' inflation targeting, exchange rate overshooting induced by a monetary policy shock is less pronounced under rational speculation than under static speculation. FOREX market equilibrium doesn't exist at all if speculation is static and monetary policy adopts'strict' inflation targeting
