Frequency of GJB2 mutations, GJB6-D13S1830 and GJB6-D13S1854 deletions among patients with non-syndromic hearing loss from the central region of Iran.

Background: In the present study, we investigate the prevalence of the GJB2 gene mutations, and deletions in the GJB6 gene, namely del (GJB6-D13S1830) and del (GJB6-D13S1854), in patients with autosomal recessive non-syndromic hearing loss (ARNSHL) from the central region of Iran.

Methods: One hundred and thirty-one unrelated ARNSHL cases from the central part of Iran were recruited. Among them, 81% (106 cases) had at least two affected relatives.

Diagnosis and treatment of disseminated intravascular coagulation: a case report.

Disseminated intravascular coagulation is a pathologic syndrome with different medical disorders. Diagnosis and treatment of this syndrome is one of the difficult managements in medical science. Thromboelastogram is the only guide for early diagnosis and precise management of this syndrome.

Evaluating the relationship between arterial blood pressure changes and indices of pulse oximetric plethysmography.

Unlabelled: The finger plethysmographic waveform of pulse oximeters is a qualitative indicator of fingertip perfusion. This waveform has been used to assess the depth of anesthesia. Its cyclical changes associated with mechanical ventilation have also been used to detect changes in blood volume under normotensive conditions and has revealed that minimal normotensive hypovolemia can cause a significant increase in the delta-down component of this waveform.
