Anterior interosseous nerve syndrome: retrospective analysis of 14 patients
Introduction: The anterior interosseous nerve (AIN) is a only motor nerve innervating the deep muscles of the forearm. Its compression is rare. We present a retrospective analysis of 14 patients with an AIN syndrome with a variety of clinical manifestations who underwent operative and conservative treatment. Patients and methods: Fourteen patients (six female, eight male, mean age 48 ± 9 years) were included. In six patients, the right limb was affected, and in eight patients the left limb. Conservative treatment was started for every patient. If no signs of recovery appeared within 3 months, operative exploration was performed. Final assessment was performed between 2 and 9 years after the onset of paralysis (mean duration of follow-up 46 ± 11 months). Patients were examined clinically for return of power, range of motion, pinch and grip strengths. Also the disability of the arm, shoulder, and hand (DASH) score was calculated. Results: Seven of our 14 patients had incomplete AIN palsy with isolated total loss of function of flexor pollicis longus (FPL), five of FPL and flexor digitorum profundus (FDP)1 simultaneously, and two of FDP1. Weakness of FDP2 could be seen in four patients. Pronator teres was paralysed in two patients. Pain in the forearm was present in nine patients. Four patients had predisposing factors. Eight patients treated conservatively exhibited spontaneous recovery from their paralysis during 3-12 months after the onset. In six patients, the AIN was explored 12 weeks after the initial symptoms and released from compressing structures. Thirteen patients showed good limb function. In one patient with poor result a tendon transfer was necessary. The DASH score of patients treated conservatively and operatively presented no significant difference. Conclusion: AIN syndrome can have different clinical manifestations. If no signs of spontaneous recovery appear within 12 weeks, operative treatment should be performed

Support for global climate reorganization during the "Medieval Climate Anomaly"
Widely distributed proxy records indicate that
the Medieval Climate Anomaly (MCA; *900–1350 AD)
was characterized by coherent shifts in large-scale Northern
Hemisphere atmospheric circulation patterns. Although
cooler sea surface temperatures in the central and eastern
equatorial Pacific can explain some aspects of medieval
circulation changes, they are not sufficient to account for
other notable features, including widespread aridity
through the Eurasian sub-tropics, stronger winter westerlies
across the North Atlantic and Western Europe, and shifts in
monsoon rainfall patterns across Africa and South Asia.
We present results from a full-physics coupled climate
model showing that a slight warming of the tropical Indian
and western Pacific Oceans relative to the other tropical
ocean basins can induce a broad range of the medieval
circulation and climate changes indicated by proxy data,
including many of those not explained by a cooler tropical
Pacific alone. Important aspects of the results resemble
those from previous simulations examining the climatic
response to the rapid Indian Ocean warming during the late
twentieth century, and to results from climate warming
simulations—especially in indicating an expansion of the
Northern Hemisphere Hadley circulation. Notably, the
pattern of tropical Indo-Pacific sea surface temperature
(SST) change responsible for producing the proxy-model
similarity in our results agrees well with MCA-LIA SST
differences obtained in a recent proxy-based climate field
reconstruction. Though much remains unclear, our results
indicate that the MCA was characterized by an enhanced
zonal Indo-Pacific SST gradient with resulting changes in
Northern Hemisphere tropical and extra-tropical circulation
patterns and hydroclimate regimes, linkages that may
explain the coherent regional climate shifts indicated by
proxy records from across the planet. The findings provide
new perspectives on the nature and possible causes of the
MCA—a remarkable, yet incompletely understood episode

Multimessenger search for sources of gravitational waves and high-energy neutrinos: Initial results for LIGO-Virgo and IceCube
We report the results of a multimessenger search for coincident signals from the LIGO and Virgo gravitational-wave observatories and the partially completed IceCube high-energy neutrino detector, including periods of joint operation between 2007-2010. These include parts of the 2005-2007 run and the 2009-2010 run for LIGO-Virgo, and IceCube's observation periods with 22, 59 and 79 strings. We find no significant coincident events, and use the search results to derive upper limits on the rate of joint sources for a range of source emission parameters. For the optimistic assumption of gravitational-wave emission energy of 10-2 M⊙c2 at ˜150 Hz with ˜60 ms duration, and high-energy neutrino emission of 1 051 erg comparable to the isotropic gamma-ray energy of gamma-ray bursts, we limit the source rate below 1.6 ×1 0-2 Mpc-3 yr-1 . We also examine how combining information from gravitational waves and neutrinos will aid discovery in the advanced gravitational-wave detector era.status: publishe
