Epidemics of malaria in the East

[1] The circulation and SST anomalies during the post El Niño Asian summer monsoon season were examined through data analysis and linear equatorial b plane model calculations. Over the Philippine Sea, a negative precipitation anomaly and low-level anti-cyclonic anomaly were found. Over the western equatorial Pacific, a low-level easterly anomaly prevailed. An east-west SST anomaly contrast dominated over the tropical Indian and Pacific Oceans, with positive anomalies over the Indian and western Pacific Oceans and negative anomalies over the central to eastern Pacific. The b plane model demonstrated that the anti-cyclonic anomaly over the Philippine Sea was a Rossby response to the negative precipitation anomaly found in this region. The easterly anomaly along the equator was part of a Kelvin response to the SST anomaly contrast. On the northern side of this anomalous easterly, a negative vorticity anomaly developed. This could induce the moist Rossby wave over the Philippine Sea. Citation: Terao, T., and T.

When small, asymptomatic hemorrhages were included in the estimation, the actual rate of hemorrhage was higher than that previously reported. Judging from the incidence of hemorrhage during coagulation and DBS surgeries, the authors suggest that the heat induced by coagulation may play a larger role than microelectrode penetration in the development of hemorrhage.

A 58-year-old man presented with an intramedullary spinal cord abscess (ISCA) manifesting as posterior neck pain, gait disturbance, and urinary retention, and transverse myelopathy 1 week later. Magnetic resonance imaging showed the ISCA at the C7 to T1 levels. He was treated under a diagnosis of cryptogenic ISCA with high-dose ampicillin and third- or fourth-generation cephalosporins, which resulted in complete recovery after 2 months. Review of the literature between January 1998 and August 2007 identified 26 cases of ISCA, including our patient. We also identified two additional nonsurgically treated ISCA patients reported between 1977 and 2007. The most common presentation was motor deficits in all patients, followed by fever, pain, and bladder dysfunction. The mortality rate was 1 of 26 patients, and neurological sequelae were observed in 15 of the 25 surviving patients. There was no significant difference in the frequency of neurological sequelae between surgically and nonsurgically treated patients. Mean length of the abscess in the surgically treated group was significantly larger than that in the medically treated group (5.8 vs. 2.2 vertebral bodies). All three nonsurgically treated patients with neurological sequelae had anaerobic infections and received antibiotic therapy later and for shorter periods than those with complete neurological recovery. Antibiotic treatment is comparable to surgery plus antibiotic treatment. Early broad-spectrum high-dose ampicillin and third-generation cephalosporin, covering Gram-positive, Gram-negative, and anaerobic organisms, should be the first choice of management for patients with ISCA.

BackgroundBirth weight and length have seasonal fluctuations. However, it is uncertain which meteorological element has an effect on birth outcomes and which timing of pregnancy would explain such effect. Therefore, the purpose of this study was to examine temperature effects during pregnancy and which timing of pregnancy has effects on size at birth.MethodsA large, randomized, controlled trial of food and micronutrient supplementation for pregnant women was conducted in Matlab, Bangladesh (MINIMat Study), where women were enrolled from November 2001 to October 2003. The fetal growth data which included the size at birth and information of their mothers were obtained (n = 3267). Meteorological data such as temperature, precipitation, relative humidity, and daily sunshine hours during pregnancy were observed at the nearest observatory site of Bangladesh Meteorological Department.ResultsInfants born in colder months (November–January) were shorter than those born in hot and dry, and monsoon months (mean (SD) of birth length was 47.5 cm (2.2) vs. 47.8 cm (2.1) vs. 47.9 cm (2.1) respectively; P < 0.001). Increased temperature during the last month of pregnancy was significantly related with increased birth length with adjustment for gestational weeks and the season at birth, and remained significant with further adjustments for precipitation, sex of infants, maternal early-pregnancy BMI, parity, and education status of the mother (P < 0.01). On the other hand, increased temperature at mid-gestation was associated with increased birth weight (P < 0.05).ConclusionsThese findings suggest that temperature affects both birth weight and length. The more temperature increased at the last month of pregnancy, birth length became longer. For birth weight, the temperature at mid-pregnancy affected in a positive way.Electronic supplementary materialThe online version of this article (doi:10.1186/s41182-016-0041-6) contains supplementary material, which is available to authorized users.
