Spigelian hernia: CT and ultrasonography diagnosis

The diagnostic potential of CT and sonography in detecting clinically unrecognized cases of spigelian hernia is illustrated and discussed. These imaging modalities can promptly and reliably diagnose spigelian hernia based on the following findings: (1) peritoneal and muscular defect along the spigelian line in the lower abdomen; (2) intraparietal location of the hernial sac; and (3) hernial sac containing omentum and/or mesentery and loops of bowel. Two recently diagnosed cases are presented together with a short review of the literature.     

Biomechanical comparison of the three techniques for arthroscopic suprapectoral biceps tenodesis: implant-free intraosseous tendon fixation with Cobra Guide,interference screw and suture anchor

Synthesis,supramolecular organization and thermotropic phase behaviour of N-acyltris(hydroxymethyl)aminomethane

Herein, we reported the supramolecular organization of N-acyltris(hydroxymethyl)aminomethane (NATM) in the solid state as well as in aqueous solution. Single crystal X-ray diffraction revealed that NATM adopts a fully interdigitized structure. The thermodynamic parameters associated with thermotropic phase behaviour of NATM was determined by differential scanning calorimetry. The molecular packing and phase state of the NATM analyzed by laurdan and prodan fluorescence supports the formation of an interdigitized phase in aqueous solution. The potential application of the self-assembled NATM vesicles was demonstrated through entrapping model drug, Rhodamine B.

Prevalence of drug resistance under the DOTS strategy in Hyderabad, South India, 2001-2003.

BACKGROUND: Multidrug-resistant tuberculosis (MDR-TB), defined as resistance to at least isoniazid (INH) and rifampicin (RMP), is considered a threat to TB control. Implementation of DOTS ensures high cure rates and prevents MDR. OBJECTIVE: To study the prevalence of MDR-TB from a retrospective analysis of the data in a tuberculosis unit where DOTS was implemented over a period of 6 years through public private mix (PPM). METHODS: Drug susceptibility testing of Mycobacterium tuberculosis samples isolated from the cultures of newly registered and retreatment sputum smear-positive cases during 2001-2003. RESULTS: During the study, 909 sputum-positive cases were registered and analysed. Of these, 714 were new and 195 were retreatment sputum-positive cases. INH resistance was found in 3.2% (23) of new and 9.2% (18) of retreatment cases. RMP resistance was present in 1.5% (11) of new and 7.2% (14) of retreatment cases. MDR was present only in 0.14% (1) of new and 2% (4) of retreatment cases. New cases had cure rates of 96% compared to 85% in retreatment cases. CONCLUSION: The prevalence of MDR-TB is low where success rates are high.     

Clinical safety profile of ticagrelor compared to clopidogrel in 1208 patients: Real world evidence

Introduction

Dual antiplatelet treatment is recommended by current clinical practice guidelines for patients undergoing PCI. The PLATO trial showed superiority of ticagrelor to clopidogrel in reducing the rate of death from vascular causes, myocardial infarction and stroke without increase in the rate of overall major bleeding in ACS patients. However, real world evidence in Indian patients is limited. The objective of this study is to compare safety profile of ticagrelor with clopidogrel in real world settings.

Defining the need for blood and blood products transfusion following suicide bombing attacks on a civilian population: A level I single-centre experience

Introduction

Knowledge of patterns of blood use in the care of mass casualty settings is important for preparedness of medical centre resources and for maximising survival when blood supplies are limited. Our objectives were to review of our experience with the use of blood products and define the utilisation of blood transfusion following suicide bombing attacks.

Patients and methods

We conducted a retrospective analysis of blood and blood product transfusion following civilian bombing attacks at a level I trauma centre in Jerusalem, Israel from 2000 to 2005. The study group consisted of 137 patients who were admitted following 17 suicide bombing attacks which were carried out in Jerusalem during the 5-year period. Demographic data, number of units of blood and blood products transfused and the need for massive transfusions were recorded and analyzed.

Results

Fifty-three patients received blood transfusions (38.7%). There were 33 males (62.2%) with a median ISS of 13 (range 4–25). These 53 patients received 524 PRBC, 42 WB, and 449 FFP. The mean number of PRBC transfused/admitted patient was 3.82 units (range 0–59). Thirty patients (21.9%) received 236 PRBC (45% of total PRBC) at the first 2 h. The ratio of ordered to transfused blood was 946:524. The FFP:PRBC ratio for all transfused patients was 1:1.17. The number of PRBC transfused per attack correlated with the number of patients admitted per attack. The most commonly transfused blood type was A (52.3%). Only 18 units of uncrossed-matched blood were transfused (3.3% of total). 14 patients (10.2%) received massive transfusions. These patients received 399 PRBC (76.1% of total units transfused) and the average number of PRBC transfused was 28.5/patient (10–59).

Conclusions

More than 1/3 of casualties admitted following civilian bombing attacks received transfusions, most in the first 2 h. Large-scale attacks will require more blood and blood products than small-scale attacks. Twice the number of PRBC ordered than transfused reflects a known trend for over-triage during the initial assessment following bombing attacks. One tenth of patients received massive transfusion.     

Diffuse Alveolar Hemorrhage Following Allogeneic Peripheral Blood Stem Cell Transplantation: A Case Report and A Short Review

Pulmonary complications are one of the most common causes of morbidity and mortality in patients undergoing peripheral blood stem cell transplantation. Both infective and non-infective etiologies can involve the lungs during this period and differentiating them clinically is a challenging task and management differs in each case. We present here a case of acute myeloid leukemia, in whom following allogeneic peripheral blood stem cell transplantation, diffuse alveolar hemorrhage developed.
