Nucleoside reverse-transcriptase inhibitors (NRTIs) have been associated with functional and structural mitochondrial abnormalities, leading to several adverse events, such as increased serum lactic acid levels and lactic acidosis. Mild-to-moderate, asymptomatic hyperlactataemia has been frequently reported in human immunodeficiency virus (HIV)-infected patients treated with NRTIs, with an estimated prevalence between 15% and 35%. On the contrary, symptomatic, severe hyperlactataemia and lactic acidosis are less common, with an incidence ranging from 1.7 to 25.2 cases per 1000 person-years of antiretroviral treatment, and are associated with a remarkable mortality rate, which varies from 30% to 60% in different studies. The clinical presentation of lactic acid syndrome is non-specific and includes asthenia, malaise, nausea, vomiting, abdominal pain, weight loss, tachypnoea, dyspnoea, liver steatosis and increased transaminase levels, and risk factors include previous or concurrent therapy with stavudine or didanosine. Management of symptomatic lactic acid alterations involves NRTI-therapy interruption and supportive care, while natural history of hyperlactataemia is still unknown, and it is uncertain whether asymptomatic patients with increased lactate concentrations are at increased risk of developing lactic acidosis.

To induce luteal regression-related abortion/delivery and treat pyometra in dogs, various PGF2alpha-analogues (PGAs) are administered, but a PGA most appropriate for clinical application in dogs, with a low incidence of side effects, is being investigated. In this study, we compared the effects of etiproston tromethamine (PGA-E), which has not been investigated in dogs, with those of cloprostenol (PGA-C), which is routinely used in dogs. A single dose of PGA-E at 100, 200, 400 or 800 microg or PGA-C at 12.5, 25, 50 or 100 microg was administered to beagles (n=5 per group) 25 days after ovulation, when the corpus luteum was in the functional phase. We compared the state of luteal regression by measuring plasma progesterone levels. As side effects, the incidences of salivation, vomiting, tachypnea, diarrhea and the drop in body temperature were investigated. In the 400-microg and 800-microg groups treated with PGA-E, the mean intervals from administration until luteal regression were 18.6 days and 31.2 days, respectively. In the dogs treated with 50 microg or more of PGA-C, luteal regression was noted 2 days after administration. The above side effects were observed for 3 hr after administration of PGA-E/PGA-C. In the dogs treated with 800 microg of PGA-E, the mean body temperature was 36.7 degrees C 4 hr after administration; hypothermia persisted. PGA-E may be less useful than PGA-C for promoting luteal regression in dogs in clinical application.

The pine processionary moth (Thaumetopoea wilkinsoni) is an insect of medical significance in the eastern Mediterranean. This report describes three exposure cases in dogs due to ingestion of this moth's caterpillars in Israel. All three dogs were observed in direct contact with caterpillars or pinecones in infested gardens. The disease course and progression of signs were acute in all three cases, and included vomiting and severe tongue swelling. Physical examination findings included hyperthermia, tachypnoea, respiratory distress, cyanosis and tongue oedema, labial angioedema, ptyalism, bilateral submandibular lymphadenomegaly and conjunctivitis. Severe tongue necrosis and sloughing of its distal portion occurred 2-5 days after admission to the hospital. All dogs recovered and were discharged within 2-7 days of admission. Two staff members, attending one of the dogs, experienced an itchy rash and wheals on their arms, wrists and necks. To the best of our knowledge, this should be the first report of severe oral lesions and tongue necrosis due to contact with T. wilkinsoni caterpillars.

Congenital eventration of the diaphragm is uncommon. Its association with a hiatal hernia has not been reported earlier. We report a case of such an association in a 2-month-old boy who presented with tachypnea aggravated by feeding and recurrent vomiting. Diagnostic uncertainty and a unique course of postoperative recovery complicated by gastric volvulus are described. The patient underwent surgical plication of the right diaphragm, followed by an emergency hiatal repair on the first postoperative day. Timely recognition, and repair of the hiatal hernia averted a fatal complication.

A boy aged 6 months and a girl aged 9 months were admitted due to vomiting, among others, and a boy aged 11 months due to pneumonia. It turned out that they had a congenital diaphragmatic hernia. Primary operative repair was performed successfully in all patients, followed by recovery. The older boy experienced a relapse nearly 1 year later, which was treated by surgical correction. Most congenital diaphragmatic hernias present directly after birth, with cyanosis and respiratory distress. However, 10-20% of the cases are discovered after this period. In these children diagnosis can be difficult because of the diverse symptoms such as vomiting, feeding difficulties, tachypnoea or recurrent respiratory tract infections. Physical signs include the absence of breath sounds or the presence of bowel sounds in the chest. Chest X-ray, contrast upper gastrointestinal series or ultrasound imaging confirms the diagnosis. Delay in treatment can lead to complications such as necrosis of the bowel. In young children with acute or chronic respiratory infections or gastrointestinal complaints, a congenital diaphragmatic defect should be considered.

Fifteen cats from Italy with Ehrlichia-like inclusion bodies in their neutrophils were studied. They were diagnosed with Anaplasma (Ehrlichia) phagocytophilum infection on the basis of cytological observation of morulae within 1 to 21 per cent of their neutrophils, clinical signs characteristic of ehrlichiosis and their response to doxycycline. The predominant signs of disease were anorexia, lethargy, hyperaesthesia, muscle and joint pain, lameness, neck rigidity, lymphadenomegaly, gingivitis/periodontitis, conjunctivitis, weight loss, incoordination, pale mucous membranes and hyperglobulinaemia. The cat with inclusions in 21 per cent of its neutrophils had suffered arthralgia, tachypnoea, neck rigidity, vomiting and thrombocytopenia for four months, but recovered promptly after treatment with doxycycline.

A 21-year-old female with chronic membranoproliferative nephritis was admitted for suspected esophageal disruption and asthma after severe, prolonged vomiting. At the time of admission she presented with dyspnea, tachypnea, arterial hypotension and tachycardia. Physical examination showed discrete signs of ectopic air at the neck and distended cervical veins. CT-scan of the chest showed severe mediastinal emphysema with compression of the right atrium. After cervical mediastinotomy the cardiorespiratory parameters normalized immediately. Esophagoscopy showed multiple longitudinal mucosal tears between 25 and 45 cm; fluoroscopically, there was no leakage of contrast medium. Following conservative treatment the patient recovered completely and was discharged on day 8.

Accidental or intentional ingestion of carbofuran can produce a life-threatening syndrome that requires prompt diagnosis and treatment. This paper investigates unintentional carbofuran poisoning in farm workers. Thirteen patients were admitted to the emergency department with carbofuran poisoning between January 2002 and August 2004 (2 female, 11 male). The patients had been poisoned while mixing the liquid form of carbofuran with seeds. Their hands were red on admission. Complaints most commonly reported by the patients on admission were nausea, vomiting, headache, weakness, dizziness and blurred vision. The most commonly observed signs were tachycardia, tachypnea, salivation, miosis, elevated blood pressure, and fasciculation. Three patients were agitated and one was lethargic on admission. We reviewed the patients' medical charts retrospectively, as well as the demographic data, intoxication route, clinical and laboratory presentations, and outcomes. We made the diagnosis according to a compatible exposure history and clinical findings. The most commonly observed laboratory finding was hyperglycemia, which was found in 6 patients. Serum pseudocholinesterase level was low in only one patient. All the patients were cured and discharged from the hospital in good physical condition. Rapid onset, mild illness and quick recovery are typical characteristics of acute occupational carbofuran poisoning. We conclude that public health efforts should educate farm workers about the dangers of pesticide application so that its threat can be diminished.

20 children, diagnosed with scrub typhus who attended Chiang Rai Regional Hospital during a period of 6 months from June 2003 to December 2003, were studied prospectively. All cases were serologically proved to be scrub typhus by using Dipstick or indirect immunofluorescent antibody (IFA) technique. The most common clinical feature was eschar (75%). Others included hepatomegaly (65%), cough (60%), lymphadenopathy (40%), tachypnea (35%), constipation (25%), abdominal pain (20%), edema (20%), splenomegaly (15%), vomiting (15%), rash (15%) and petichia (5%) respectively. Chest radiography showed abnormalities in 85% with mostly bilateral interstitial infiltrations. Elevated of SGOT: SGPT were detected in 18 (90%) and 15 (75%) cases. Hypoalbuminemia was detected in 12 (60%) cases. Complete blood count showed PMN leukocytosis (> 60%) in 12 (60%) cases, lymphocytosis (> 40%) and atypical lymphocytosis (> 5%) in 1 (5%) case each and thrombocytopenia in 16 (80%) cases. The Weil-Felix test was positive in 1 (5%) case. Complications were pneumonia with or without pulmonary edema, meningitis and shock. Chloramphenicol and doxycycline were successfully treated and roxithromycin was not effective.

Sodium fluoroacetate (SFAC) or Compound 1080 is a potent rodenticide, largely used after 1946 for rodent and home pest control. The toxic effects of SFAC are caused by fluorocitrate action, a toxic metabolite, which has a competitive action with aconitase enzyme, leading to citrate accumulation and resulting in interference in energy production by Krebs cycle blockade. In the present study, domestic cats were intoxicated with oral doses of fluoroacetate (0.45 mg/kg). The intoxicated animals presented emesis, diarrhea with abdominal pain posture and an abdominal palpation, tachypnea, bilateral midriasis, hypothermia, hyperexcitability and convulsions. Blood gas analysis indicated decreased pH and bicarbonate levels. Serum ionized calcium was also decreased. ECG showed non-specific changes in ventricular repolarization and ventricular arrhythmias. The survival rate was 75% in the treated group with calcium gluconate and sodium succinate and 37.5% in the nontreated group.
