Intrathoracic Pressure as a Tourniquet Technic to Tamponade Bleeding Esophageal Varices

The authors' report observations on 79 cases of esophagovariceal bleeding in which ten cases were subjected to an intrathoracic tourniquet maneuver of increasing intrathoracic pressure. All esophagovariceal bleeding ceased following the maneuver. An established maneuver safety limit (holding mean transmural CVP to no higher than 4.0 cm H2O) insured cardiac output maintenance and guaranteed against maneuver-generated morbidity. The authors conclude the cessation of the bleeding from esophageal varices observed is the combined result of tourniquet-tamponade by direct venous air compression on the bleeding varices as well as general esophageal compression.     

Muckle–Wells syndrome in an Indian family associated with NLRP3 mutation

Muckle — Wells syndrome (MWS) is a rare autosomal dominant disease that belongs to a group of hereditary periodic fever syndromes. It is part of the wider spectrum of the cryopyrin-associated periodic syndrome (CAPS) which has only rarely been described in non-Caucasian individuals. It is characterized by recurrent self-limiting episodes of fever, urticaria, arthralgia, myalgia and conjunctivitis from childhood. Progressive sensorineural hearing loss and amyloidosis are two late complications. MWS is caused by gain of function mutations in the NLRP3 gene, which encodes cryopyrin, a protein involved in regulating the production of proinflammatory cytokines. We report two patients with MWS in an Indian family associated with the p.D303N mutation in the NLRP3 gene. These findings promote awareness of these hereditary periodic fever syndromes as a cause for recurrent fevers from childhood in the Indian population.KEY WORDS: Hereditary periodic fever, D303N mutation, Indian family, Muckle—Wells syndrome, p.D303N mutation     

Battle Casualty Survival with Emergency Tourniquet Use to Stop Limb Bleeding

Background

In a previous study conducted at a combat support hospital in Iraq, we reported the major lifesaving benefits of emergency tourniquets to stop bleeding in major limb trauma. Morbidity associated with tourniquet use was minor.

Study Objectives

The objective of this study is to further analyze emergency tourniquet use in combat casualty care.

Design and Setting

This report is a continuation of our previous study of tourniquet use in casualties admitted to a combat support hospital (NCT00517166 at www.ClinicalTrials.gov).

Methods

After verifying comparable methodologies for the first study and the current study, we compared patient results for these two time periods and then pooled data to analyze outcomes with a larger sample size.

Results

The total study population was 499 (232 in the previous study and 267 in the current study). In all, 862 tourniquets were applied on 651 limbs. Survival was 87% for both study periods. Morbidity rates for palsies at the level of the tourniquet were 1.7% for study 1 and 1.5% for study 2; major limb shortening was 0.4% for both. Survival was associated with prehospital application (89% vs. 78% hospital, p < 0.01) and application before the onset of shock (96% vs. 4% after).

Conclusions

This study shows consistent lifesaving benefits and low risk of emergency tourniquets to stop bleeding in major limb trauma.     

Elongated Styloid Process (Eagle''s Syndrome) Causing Hemicrania

SYNOPSIS
Hemifacial pain and hemicrania can be caused by an elongated styloid process (Eagle's syndrome). This entity is reviewed historically with six case histories and x–rays presented. The etiology of the symptom complex is unclear, but possible mechanisms such as cranial nerve pressure and carotid sympathetic nerve involvement are discussed. Specific treatment is surgical removal of the tip of the styloid process.
