MySQL query works in PHPMyAdmin but not PHP

I do not understand what's happening. I have a query in PHP who crashes -with a strange error-. When I copy/paste the exact same request in PHPMyAdmin it works as expected. What am I doing wrong here ?

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'small">(conso régulière)", IF(refluxGastro>0,"Oui","Non") as "Reflux ga' at line 1

"near 'small" <-- where is small o_O

The PHP code isn't really relevant cause you won't see a lot.

  $db = mysql_connect();
    mysql_select_db();//TODO SWITCH TO PDO
    mysql_query("SET NAMES UTF8");


    $fields = $form->getFields($form);
    $settingsForm = $form->getSettings();
    $sql = 'SELECT oms_patient.id,oms_patient.date,oms_patient.date_modif,';
    foreach ($fields as $field) {
        if (!$field->isMultiSelect()) {
            $field->select_full(&$sql, 'oms_patient', null);
        }
    }
    if (isset($settingsForm['linkTo'])) {
        $idLinkTo = 'id_' . str_replace('oms_', '', $settingsForm['linkTo']);
        $sql .= $idLinkTo;
    }

    $sql.=' FROM oms_patient';
    foreach ($fields as $field) {
        if (!$field->isMultiSelect() && $field->getTable('oms_patient')) {
            $sql .=' LEFT JOIN ' . $field->getTable('oms_patient') . ' ON ' . $field->getTable('oms_patient') . '.id = '.$field->getFieldName().' ';
        }
    }
    $sql.=' where oms_patient.id=' . $this->m_settings['e'];

    $result = mysql_query($sql) or die('Erreur SQL !<br>' . $sql . '<br>' . mysql_error());
    $data = mysql_fetch_assoc($result);

var_dump of $sql

string(2663) "SELECT oms_patient.id,oms_patient.date,oms_patient.date_modif,date_modif,AES_DECRYPT(nom,"xxxxx") as "Nom",AES_DECRYPT("prenom","xxxxx") as "Prénom usuel",DATE_FORMAT(ddn, "%d/%m/%Y") as "Date de naissance",villeNaissance as "Lieu de naissance (ville)",CONCAT(oms_departement.libelle,"(",id_departement,")") as "Lieu de vie",CONCAT(oms_pays.libelle,"(",id_pays,")") as "Pays",CONCAT(patientsexe.libelle,"(",id_sexe,")") as "Sexe",CONCAT(patientprofession.libelle,"(",id_profession,")") as "Profession", IF"...

can't go further to see what is in the output after the "..." <-- if you have an idea
