In veterinary medicine, serum creatine-kinase (CK) activity is mostly used to assess skeletal muscle damage. This retrospective study aimed to evaluate the prevalence of increased CK activity in a large, ill-cat population and to characterise associated diseases, clinical and laboratory findings and its prognostic value. Cats with a complete serum biochemistry analysis were consecutively enrolled, divided into two CK activity-based groups (within and above reference interval) and compared. The study included 601 cats. Median serum CK was 402 U/l (range 16-506870). Increased CK (>250 U/l) was observed in 364 (60%) cats, and>30-fold its upper reference limit in 43 (7%). Cats with increased CK had greater (P < or = 0.05) body weight, and were more likely to have a history of collapse, dyspnoea, abnormal lung sounds, cyanosis, shock and paraplegia, higher median serum alanine aminotransferase, aspartate aminotransferase and lactate dehydrogenase activities and total bilirubin and triglyceride concentrations, but lower, median total protein, albumin, globulin and cholesterol concentrations and proportion of anorexia than cats with normal CK. Cardiac diseases, trauma, bite wounds, systemic bacterial infections, prior anaesthesia and intramuscular injections were more common (P < or = 0.05) in cats with increased compared to normal CK activity. The hospitalisation period was longer (P=0.007) and treatment cost and mortality were higher (P<0.005) in cats with increased CK activity. However, CK activity was an inaccurate outcome predictor (area under the receiver operator characteristics curve 0.58). Increased CK activity is very common in ill cats.

Congenital central hypoventilation syndrome is a rare illness, which classically presents in the neonatal period; newborns present with shallow breathing and cyanosis, without a physiological rise in breathing rate. Incidence has been estimated from 1 in 10,000 to 1 in 200,000 live births. This case report describes the case of a young man who was asymptomatic until his presentation in acute respiratory failure at the age of 36 years. This case is reported to highlight the importance of considering this treatable illness as a potential cause of collapse and respiratory failure in adults presenting to emergency departments.

A 5-month old female Red-Holstein calf in poor condition was presented with a history of reduced appetite, respiratory disease and collapse. Clinical examination revealed an elevated heart rate and pronounced cyanosis of the mucous membranes. Heart and lung auscultation were normal. A complete blood count revealed profound polycythemia with severely increased values for packed cell volume, hemoglobin concentration and erythrocyte count. Cardiac ultrasonography revealed abnormal position of the great vessels with two arteries located in the right ventricle output tract and a high ventricular septum defect (VSD). Intracardial pressure and blood gas measurements confirmed pressure overload in the right heart, a left-to-right shunt through the VSD and a right-to-left-shunt leading to hypoxemia and secondary polycythemia. Based on poor prognosis, the animal was euthanized. Post-mortem examination confirmed the results of the further investigations conducted to determine the cause of polycythemia in this calf.

The risk of mortality and morbidity of patients with congenital heart defects (CHDs) is highest during neonatal period and increases when diagnosis and proper management are delayed. Neonates with critical CHDs may present with severe cyanosis, respiratory distress, shock, or collapse, all of which are also frequent clinical presentations of various respiratory problems or sepsis in the newborn. Early diagnosis and stabilization and timely referral to a tertiary cardiac center are crucial to improve the outcomes in neonates with CHDs. In this review, the clinical presentation of critical and potentially life-threatening CHDs is discussed along with brief case reviews to help understand the hemodynamics of these defects and ensure proper decision-making in critically ill patients.

A trichobezoar is a ball of swallowed hair that collects in the stomach and fails to pass through the intestines. Upper gastrointestinal endoscopy is usually useful for diagnosis and retrieval of a portion of the gastric Trichobezoars but can have complications. Upper airway obstruction may occur during removal of bezoar. This complication may be life threatening. We report the case of a 17-year-old girl who presented with severe anaemia and hypoproteinaemia. During diagnostic upper GI endoscopy, a large piece of hairball compressed the upper airway, leading to cyanosis, respiratory arrest and cardiovascular collapse. The patient was immediately intubated and transferred to the operation room for emergency esophagoscopy. In the operation room, after haemodynamic stabilization the otolaryngologist removed the large piece by esophagoscope. Then the patient was transferred to ICU ward with spontaneous ventilation. The day after, she became stable and conscious.

Canine non-rabies combined vaccines are widely used to protect animals from infectious agents, and also play an important role in public health. We performed a large-scale survey to investigate vaccine-associated adverse events (VAAEs), including anaphylaxis, in Japan by distributing questionnaires on VAAEs to veterinary hospitals from April 1, 2006 through May 31, 2007. Valid responses were obtained for 57,300 vaccinated dogs at 573 animal hospitals; we obtained VAAEs information for last 100 vaccinated dogs in each veterinary hospital. We found that of the 57,300, 359 dogs showed VAAEs. Of the 359 dogs, death was observed in 1, anaphylaxis in 41, dermatological signs in 244, gastrointestinal signs in 160, and other signs in 106. Onset of VAAEs was mostly observed within 12h after vaccination (n=299, 83.3%). In this study, anaphylaxis events occurred within 60 min after vaccination, and about half of these events occurred within 5 min (n=19, 46.3%). Furthermore, where anaphylaxis was reported, additional information to support the diagnosis was obtained by reinvestigation. Our resurvey of dogs with anaphylaxis yielded responses on 31 dogs; 27 of these demonstrated collapse (87.1%), 24 demonstrated cyanosis (77.4%), and both signs occurred in 22 (71.0%). Higher rates of animal VAAEs, anaphylaxis, and death were found in Japan than in other countries. Further investigations, including survey studies, will be necessary to elucidate the interaction between death and vaccination and the risk factors for VAAEs, and thus develop safer vaccines. Moreover, it may also be necessary to continually update the data of VAAEs.

A 13-year-old neutered male Maltese was referred for paroxysms of coughing and cyanosis, with radiographic evidence of bronchial disease and cardiomegaly. Investigation with echocardiography, bronchoscopy, fluoroscopy and bronchoalveolar lavage led to a diagnosis of myxomatous mitral valve degeneration with insufficiency, ISACHC class II heart failure and bronchomalacia with severe left mainstem bronchial collapse. Persistence of intractable cough despite medical therapy prompted placement of a stent in the left mainstem bronchus. Immediately after stent placement, severe pulmonary oedema developed, thought to be due to compression of the left atrium by the stent or acute lung injury related to stent placement. The dog recovered over a 3-day period with diuretic therapy and positive end expiratory pressure ventilation. Subsequently, the dog died from congestive heart failure 102 days after stent placement, during which time occasional, self limiting coughing episodes occurred.

The aim of this study was to investigate the clinical background and identify the risk factors for perioperative respiratory complication in pediatric patients with sleep-disordered breathing (SDB) who underwent adenotonsillectomy (AT). Of the 186 pediatric subjects (male: 131, female: 55) undergoing AT as the first surgical treatment for SDB, 14 patients (male: 9, female: 5) fulfilled the following criteria: 1) disturbed ventilation, 2) cyanosis with an oxygen saturation of less than 90% on pulse oximetry during the perioperative period and 3) the subsequent need for medical intervention, including immediate intubation, continuous positive airway pressure (CPAP) or airway insertion. Among these 14 patients, nine were less than 3 years of age. In addition, 5 and 3 patients had hypotonia due to cerebral paralysis and metabolic disturbances, respectively. Seven had a short stature with an SD of worse than - 1.5. A statistical analysis showed that cases with either an age of less than 3 years, hypotonia or a short stature had a high risk for suffering from respiratory complications, and suggested that low body weight and a high value for preoperative apnea-hypopnea index were additional risk factors. However, a chart review exhibited that, of the 14 cases with respiratory complications, the 8 cases whose age was under 3 years had either of hypotonia or a short stature. In thirteen of the 14 cases, respiratory complications were associated with the process of general anesthesia, and ten patients exhibited pharyngeal collapse. After surgery, 7 and 3 patients required intensive care in the ICU and the pediatric recovery unit, respectively. Based on these results, it is suggested that pediatric SDB cases under 3 years of age and either with hypotonia or a short stature have a high risk for respiratory complications associated with AT, and therefore AT for such patients should only be performed in medical facilities with an ICU or an equivalent department.

Enterovirus infections are common in the neonatal period. Newborns are at a higher risk of severe disease including meningoencephalitis, sepsis syndrome, cardiovascular collapse, or hepatitis. The mechanism of heart failure in patients with enterovirus infection remains unknown. Early diagnosis may help clinicians predict complications in those infants initially presenting with severe disease. An 11-day-old male newborn was admitted to our neonatal intensive care unit because of tachycardia and crises of cyanosis. His elder brother had febrile illness. The newborn was cyanotic, in respiratory distress, with tachycardia, low blood pressure and prolonged capillary refilling time. Limb pulse oximeter was around 85%. During the first day of hospitalization, the newborn had one febrile episode. Laboratory data: elevated transaminases, markers of inflammation negative, all bacterial cultures negative. Enterovirus RNA was detected in blood sample. Other blood findings were without significant abnormalities. Electrocardiogram showed tachycardia, with narrow QRS complexes (atrial tachycardia) and heart rate up to 280/min. In order to convert the rhythm, the patient was administered adenosine and amiodarone. In the further course of hospitalization, the patient was in good general condition, eucardiac and eupneic. Newborns with tachycardia and a family history of febrile illness should be suspected to have enterovirus infection. Enterovirus infection is a highly contagious and potentially life-threatening infection if not detected early. The use of sensitive molecular-based amplification methods offers potential benefits for early diagnosis and timely treatment.

Pneumocephalus is a clinical condition caused by dysbarism, trauma, and iatrogenic causes. The most common iatrogenic causes of pneumocephalus are major interventions as a neurosurgery and cardiovascular operations, endoscopy, and minor interventions as a peripheral and central venous access. Especially during insertion of central venous line and intravenous drug and fluid infusion, the venous air embolism may occur in emergency department. In these patients, retrograde pneumocephalus occurs as a result of the air entering the right atrium to the brain. Clinical effects of the air delivery rates are known to be more specific than the total amount of air. In general, intravenous administration of 300 to 500 mL air in the speed of 100 mL/min is considered to be lethal. Large amounts of air embolism can cause hypotension and acute circulatory collapse with intracardiac obstruction. The most common symptoms of venous air embolism are anxiety, dyspnea, chest pain, cyanosis, tachycardia, tachypnea, headache, confusion, agitation, syncope, slurred speech, blurred vision, seizures, and ataxia. The mortality of pneumocephalus caused by central venous catheters in patients presented with symptoms of focal neurologic was 8%, whereas the mortality of pneumocephalus in patients presented with encephalopathy was 36%. In our report, a case of pneumocephalus secondary to disconnection of catheter cap in chronic renal failure patient who has hemodialysis via catheter has been presented.
