Neonatal subgaleal haematoma: Associated risk factors, complications and outcome

Objective : To describe the obstetric and perinatal factors, in particular the method of delivery, associated with development of a subgaleal haematoma (SGH) and to determine the outcome of survivors with this type of birth trauma. Methodology : Perinatal and obstetric data were retrospectively reviewed for 37 infants admitted to the neonatal unit of the sole tertiary paediatric referral hospital in Western Australia with an SGH, over a 24 year period from 1970 to 1993. These data were compared to data for all Western Australian births. The long-term outcome was obtained through medical and private paediatric records for 26 of these infants. Results : All except one of the neonates had instrumental deliveries; 89% had a vacuum extractor applied to the head at some stage of delivery compared to 10% of the general population of births in Western Australia. There was also a significantly increased risk of failure of attempted vacuum extraction. Of the cases where a vacuum extraction was attempted, 45% also had forceps applied to the head. Coagulopathy was associated with the severity of the SGH. There was also a high frequency of occurrence (40%) of associated head trauma such as intracranial haemorrhage, skull fracture and cerebral oedema, as well as neonatal encephalopathy (73%). The occurrence of these associated features did not correlate significantly with the severity of SGH. Minor complications of SGH included jaundice and facial bruising. There was an excess mortality associated with SGH; however, the long-term outcome for neonatal survivors with this disorder was good. None of the cases studied subsequently developed cerebral palsy or intellectual disability, and minor neurological sequelae only were documented in four infants. Conclusions : SGH is an uncommon type of birth trauma, and is associated with delivery or attempted delivery by vacuum extraction. The most commonly associated clinical problems were hypovolaemia and coagulopathy. The long-term outcome for neonates with this condition is good.     

Efficacy and limits of the bariatric surgery

Morbid obesity is associated with and increased risk of serious comorbidities, including type 2 diabetes, sleep apnoea, cardiovascular diseases, and orthopedic disabilities. Not operative treatments for superobese patients have not been shown to produce reliable long-term benefits, therefore surgical therapy has became the treatment of choice. The number of surgical procedures increased in the last year confirm these data. However, before recommended a specific surgical procedures to a superobese patients it is necessary to consider some variables, such as: patient, health structure, and multidisciplinary equipe. Since there are not recommended or condemned surgical procedures, in this paper the Authors tried to evaluate the effectiveness and limits of the most performed surgical procedures for the treatment of pathologic obesity: gastric by-pass, biliopancreatic diversion (duodenal switch), vertical gastroplasty, banding gastric. The Authors used some pointer of outcome to measure effectiveness and limits: five year post-operative percentage excess weight loss >/< 50, peri-operative >/< 1%, early and late complications >/< 15%, reoperation >/< 3%, improvement of quality of life. Thanks to new surgical technique, restrictive options are losing ground, while malabsorbitive bariatric procedures are collecting successful.     

Fate of excluded popliteal artery aneurysms: should we change our current treatment?

Surgical repair of popliteal artery aneurysms is usually performed by vascular exclusion and femoro-popliteal bypass grafting via a medial route. The vascular exclusion of a popliteal artery aneurysm may, however, prove ineffective long-term. We report on a patient with a large popliteal artery aneurysm observed twelve years after conventional surgical treatment and discuss alternative surgical options to be considered for long-lasting effective popliteal artery aneurysm treatment.     

The peripheral lymphocyte count as an aid in the clinical staging of lung cancer.

The association between disease staging and peripheral lymphocyte count (PLC) was studied in 178 patients with histologically verified lung cancer. Mean PLC varied inversely with the stage of disease (p less than .01). The mean values were 2821, 2217, and 1594 for Stages I, II and III respectively. Thoretical normal distributions were generated about the mean peripheral lymphocyte count for each stage. Relative frequencies of lung cancer staging based on the PLC are estimated utilizing these curves.     

Seeing the mind: considerations on visual metaphors of the mind in Western thought (16th-18th centuries)

Throughout the centuries, in Western culture, scientists, philosophers, and artists have been fascinated by the working of the mind. They have attempted to translate this into visual models that are able to provide tangible references to otherwise abstract concepts. These metaphors are deeply rooted in culture and their significance encompasses ideas which shape and characterize different epochs. With a consideration of visual models of the mind developed in Western thought during the 16th and 18th centuries, this article aims to provide an overview of some of the most significant metaphors developed to illustrate the working of the mind and highlight their broader cultural significance. Generally, models used to describe the brain, and consequently to conceptualize the mind, match the most recent technical achievements or important cultural developments. They illustrate the processes through which material reality and the self are perceived and represented. This article shows how these models betray broader cultural concerns and testify to the zeitgeist of an epoch.     

Exogenous luteinizing hormone activity may influence the treatment outcome in in vitro fertilization but not in intracytoplasmic sperm injection cycles

Additional analysis of a multinational, open-label, randomized study comparing highly purified hMG and recombinant FSH in a long protocol revealed that LH activity might favorably influence pregnancy outcome in IVF cycles.     

Perioperative Management and Monitoring of a Super-obese Patient

Anesthetic management of super-obese patients is inferred from evidence which has been based on obese or morbidly obese patients. We present the perioperative management and monitoring of a 44-year-old 232-kg patient (BMI 70) admitted for laparoscopic gastric bypass surgery. Awake fiberoptic endotracheal intubation preceded induction with propofol and rocuronium. Anesthesia was maintained with desflurane and remifentanil. Desflurane was titrated on BIS values, whereas remifentanil was based on hemodynamic monitoring (invasive arterial pressure and HemoSonic™). Rocuronium was administered based on ideal body weight and recovery of twitch tension. Safe and rapid extubation in the operating theatre was made possible by the use of short-acting agents coupled with continuous intraoperative monitoring. Recovery in the post-anesthesia care unit was uneventful, pain was managed with meperidine, and after 5 hours the patient was discharged to the surgical ward. Oxygen therapy and SpO2 monitoring were continued overnight. No desaturation episodes were recorded. Pain was managed with I.V. drip of ketorolac and tramadole.
