Background: Major advances in the treatment of perinatal asphyxial–hypoxic ischemic encephalopathy followed the translation of hypothermia animal studies into successful randomized controlled clinical trials that substantially influenced the current standard of care.

Objectives: To present our preliminary experience with the first cases of clinical application of therapeutic hypothermia for PA-HIE[1] in what we believe is the first report on non-experimental hypothermia for PA-HIE from Israel.

Methods: We reviewed the medical records, imaging scans, electroencephalograms and outcome data of the six identified asphyxiated newborns who were managed with hypothermia in our services in 2008–2009.

Results: All asphyxiated newborns required resuscitation and were encephalopathic. Systemic hypothermia (33.5ºC) was begun at a median age of 4.2 hours of life (range 2.5–6 hours) and continued for 3 days. All six infants showed a significantly depressed amplitude integrated electroencephalography background, and five had electrographic seizures. One infant died (16%) after 3.5 days. Major complications included fat necrosis and hypercalcemia (n=1), pneumothorax (n=1), and meconium aspiration syndrome (n=2). None of the infants developed major bleeding. Neurodevelopmental follow-up of the five surviving infants at median age 7.2 months (4.1–18.5 months) revealed developmental delays (Battelle screening), with their motor scores ranging from -1 to +1 standard deviation (Bayley scale). None developed feeding problems, oculomotor abnormalities, spasticity or seizures.

Conclusions: Our preliminary experience with this novel modality in a large Tel Aviv neonatal service is consistent with the clinical findings of published trials.

Background: The most common and most serious complication of varicella (chickenpox) in adults is pneumonia, which can lead to severe respiratory failure. Varicella pneumonia is associated with considerable morbidity and even death.

Objectives: To summarize our experience with varicella pneumonia in terms of clinical, laboratory and radiological characteristics as well as risk factors, management and outcome.

Methods: We conducted a retrospective cohort survey in our facility from 1995 to 2008.

Results: Our cohort comprised 21 patients with varicella pneumonia, of whom 19 (90%) were men; their mean age was 35 ± 10.5 years. Nineteen patients (90%) were Bedouins and 18 (86%) were smokers. Eleven (52%) were admitted to the Medical Intensive Care Unit; 3 of them required mechanical ventilation and the remaining 10 (48%) were admitted to the general medical ward. Median length of stay was 6 ± 7.7 days. Hypoxemia and elevated lactate dehydrogenase on admission were associated with respiratory failure. Radiological manifestations were variable and nine patients exhibited characteristic findings. All but one patient were treated with acyclovir. All patients fully recovered.

Conclusions: In southern Israel varicella pneumonia is primarily a disease of young male Bedouins who are smokers. Severity ranges from mild disease to severe, resulting at times in respiratory failure requiring mechanical ventilation. Prognosis is favorable with complete recovery.

Background: Peritoneal carcinomatosis is an advanced form of cancer with poor prognosis that in the past was treated mainly palliatively. Today, the definitive approach to peritoneal surface malignancy involves peritonectomy, visceral resection and perioperative intra-abdominal hyperthermic chemotherapy. The anticipated results range from at least palliative to as far as intent to cure. Proper patient selection is mandatory.

Objectives: To determine whether cytoreductive surgery and intraperitoneal hyperthermic chemotherapy can extend survival, and with minor complications only, in patients with peritoneal carcinomatosis.

Methods: Twenty-two IPHP[1] procedures were performed in 17 patients with peritoneal carcinomatosis in our institution between 1998 and 2007: 6 had pseudomyxoma peritonei, 5 had colorectal carcinoma, 3 had ovarian cancer and 3 had mesotheliomas. All patients underwent cytoreductive surgery, leaving only residual metastasis < 1 cm in size. Intraperitoneal chemotherapy was administered through four large catheters (2F) using a closed system of two pumps, a heat exchanger and two filters. After the patient’s abdominal temperature reached 41°C, 30–60 mg mitomycin C was circulated intraperitoneally for 1 hour.

Results: The patients had a variety of anastomoses. None demonstrated anastomotic leak and none experienced major complications. Six patients had minor complications (pleural effusion, leukopenia, fever, prolonged paralytic ileus, sepsis), two of which may be attributed to chemotherapy toxicity (leukopenia). There was no perioperative mortality. Some patients have survived more than 5 years.

Conclusions: IPHP is a safe treatment modality for patients with peritoneal carcinomatosis. It has an acceptable complications rate and ensures a marked improvement in survival and in the quality of life in selected patients.

Background: Unconscious adults with spontaneous circulation after out-of-hospital cardiac arrest should be cooled to 32–34ºC (ILCOR recommendations, 2003) when the initial rhythm is ventricular fibrillation.

Objectives: To assess the technique, safety and efficacy of mild induced hypothermia in patients after OHCA[1] due to VF[2].

Methods: Patients were cooled using the MTRE CritiCoolÔ external cooling system. Cold intravenous fluids were added to achieve faster cooling in 17 patients. Data were collected prospectively and patients were analyzed according to their neurological outcome on discharge, defined by their cerebral performance category.

Results: From February 2002 to September 2006, 51 comatose VF patients with OHCA underwent MIH[3]. Treatment was discontinued early in five because of hemodynamic instability; goal temperature was reached in 98% and maintained for an average of 19.5 hours; 61% had a favorable outcome (CPC[4] 1–2) and 37% died. Improved outcome was observed with longer hypothermia time and possibly when time from collapse to return of spontaneous circulation was < 25 minutes.

Conclusions: MIH, using an external cooling system, is simple and feasible, reduces mortality and protects neurological function. Four major factors seem to influence outcome: age, co-morbidities, duration of hypothermia, and possibly the length of time from collapse to ROSC[5].

Background: Corneal erosions, a common and very painful ailment, are traditionally treated with pressure patches and antibiotic ointment but the healing is slow.

Objectives: To report our experience with the use of therapeutic contact lenses for the primary treatment of traumatic corneal erosions.

Methods: During the last 5 years in a single community clinic 65 consecutive patients with traumatic corneal erosions were treated with a corneal contact lens and antibiotic drops as a routine measure. The charts were reviewed for outcome, side effects and complications.

Results: Healing of the corneal erosions occurred within 1 to 3 days in all patients, with minimal or no pain. No corneal infection occurred. One patient had a recurrence that was successfully treated by lens placement.

Conclusions: The therapeutic contact lens with antibiotic drops is a safe and effective method to treat traumatic corneal erosions, and patients can immediately resume their regular activities.
