Successful cryoablation of incessant fast-slow atypical atrioventricular nodal reentrant tachycardia in a child with tachycardia-induced cardiomyopathy.

A 15-year-old female patient presented at the clinic with heart failure (HF). A 12-lead electrocardiogram showed a heart rate of 170 bpm; negative P waves in leads DII, DIII, aVF; and long RP tachycardia (LRPT). Echocardiography demonstrated a shortening fraction (SF) of 20%. An electrophysiology study during tachycardia revealed an atrial-His time of 52 milliseconds and a His-atrial interval of 295 milliseconds. During ventricular entrainment, the postpacing interval-tachycardia cycle length was measured at 225 milliseconds. There was a pseudo V-A-A-V response. These findings confirmed the diagnosis of atypical atrioventricular nodal re-entrant tachycardia (aAVNRT). Successful slow pathway cryoablation was performed with an 8-mm-tip cryocatheter. After 2 weeks, the SF was measured as 34%. During a 2-year follow-up period, no recurrence was observed. In conclusion, fast-slow aAVNRT should be a part of the differential diagnosis of incessant LRPT leading to HF. Cryoablation can be used successfully in cases of aAVNRT.

Factors affecting mortality among victims of electrical burns.

BACKGROUND: The aim of this study was to determine the factors affecting mortality rate among patients with an electrical burn. METHODS: A total of 115 patients admitted to the emergency department and hospitalized in the Burn Treatment Center or Intensive Care Unit (ICU) due to the electrical burn, were included in the study. RESULTS: A total of 115 patients (4 female and 111 male) with a mean age of 32.88±12.87 years were included in the study. The mean hospitalization period was 25.03±20.50 days, and the mean total body surface area burned (% TBSA) was 22.83±15.54%. Among those patients, 9 (8.5%) expired, and the remaining 106 were discharged after treatment. In a logistic regression analysis, TBSA >20% (p=0.02, OR: 11.7, CI: 1.38-99.16); ICU requirement (p=0.005, OR: 1.28, CI: 1.08-1.58); erythrocyte transfusion requirement (p=0.02, OR: 12.48, CI: 1.44-107.83); fresh frozen plasma (FFP) requirement (p=0.03, OR: 10.23, CI: 1.18-88.17); albumin requirement (p=0.02, OR: 12.60, CI: 1.44-109.85); admission serum albumin level <3.5 mg/dl (p=0.04, OR: 7.25, CI: 0.82-63.64); and admission hemoglobin level <12 mg/dl (p=0.01, OR: 8.29, CI: 1.57-43.61) were determined as risk factors for mortality in patients with electrical burns. CONCLUSION: In clinical practice, defining a mortality risk analyzer using these factors may be helpful in the management of patients with electrical burns. Additional, more comprehensive studies are required to define the risk factors for mortality and long-term morbidities in patients with electrical burns.

General characteristics of paint thinner burns: Single center experience.

BACKGROUND: The aim of the present study was to present characteristic features and risk factors of paint thinner burns in order to raise awareness and help prevent these injuries. METHODS: Records of patients admitted to the burn unit due to paint thinner burns were retrospectively reviewed, and patients with comprehensive data available were included in the study. Total of 48 patients (3 female and 45 male) with mean age of 27.79±11.49 years (range: 4-58 years) were included in the study. RESULTS: Mean total hospitalization period was 30.25±27.11 days (range: 3-110 days), and mean total burn surface area was 32.53±24.06% (range: 3.0-90.0%). In 31 cases (64.6%), intensive care unit admission was required. Among all 48 patients, 9 (18.8%) died in hospital and remaining 38 were discharged after treatment. Primary cause of death was septicemia (n=7) or respiratory failure (n=6). Inhalation injury was present in 12 of the patients, 6 of whom died (50%). Statistically significant differences were found between expired and discharged patients when compared for presence of inhalation injury (p=0.01) and septicemia (p=0.031). CONCLUSION: Ignition of paint thinner is an important cause of burn injuries that may result in very severe clinical picture. Patients require prompt and careful treatment. Clinicians should be aware that inhalation injury and sepsis are the 2 main factors affecting mortality rate in this group of patients. With increased awareness, preventive measures may be defined. Further studies are warranted to decrease mortality rate in this subgroup of burn patients.

Retroperitoneal Ganglioneuroma: Mimicking an ovarian mass in a child.

UNLABELLED: Ganglioneuroma are rare, benign neural tumor of sympathetic nervous system originating from neural crest sympathogonia. Pelvic ganglioneuromas may mimic ovarian masses. We present a patient operated with the diagnosis of ovarian tumor which had a pelvic gangliuoneuroma. CASE: An eleven-year old female patient complaining of abdominal pain and a mass was seen at our hospital. On examination a 10×10 cm mass was palpable in the pelvis. Laboratory parameters were all normal and the tumor markers such as ß-HCG, AFP, CEA, serum catecholamines were negative. Abdominal ultrasonography and computed tomography showed an 11×6×9 cm solid mass containing calcification. The preoperative diagnosis was an adnexal mass of ovary. The patient was operated under general anesthesia and we found a retroperitoneal mass attached to the spine at L5. The tumoral mass was completely excised. Histopathological examination of tumor was reported as ganglioneuroma. The patient was discharged on seventh day of hospitalization with no neurological deficit. Retroperitoneal ganglioneuromas are usually present with local mass a benign tumoral course. The preoperative diagnosis may be difficult in pelvic ganglioneuromas due to close similarity with the ovarian masses. The treatment of the ganglioneuroma is total surgical excision and histology provides a confirmatory diagnosis.
