Muscular sufficiency, serum protein, enzymes and bioenergetic studies (31-phosphorus magnetic resonance spectroscopy) in chronic malnutrition

Muscle sufficiency was significantly lower in 1336 children with chronic malnutrition of moderate to severe degree. Eighteen children with a chronic moderate degree of malnutrition and 8 well-nourished, age-matched controls were selected for biochemical and 31-phosphorus magnetic resonance spectroscopy (31 -P MRS) studies. The results showed that: (a) serum total protein, albumin, iron, calcium and inorganic phosphate were similar in both groups; (b) serum enzyme levels were significantly increased in the malnourished group; (c) 31-P MRS showed significantly higher means for total ATP, β-ATP, a-ATP and inorganic phosphate for the malnourished compared to the control group. In chronic malnutrition, proteins are maintained by degradation in muscle resulting in release of amino acids and enzymes. 31-P MRS studies showing increases in total ATP, β-ATP and inorganic phosphate and a decrease in phosphocreatine suggest that ATP is maintained at the cost of phosphocreatine.     

Pathological complications of non-survivors of newborn extracorporeal membrane oxygenation

The pathology was reviewed of the early deaths identified from the first 50 neonates treated with extracorporeal membrane oxygenation (ECMO) during its introduction to the UK. Fifteen neonates died during or shortly after ECMO between August 1989 and June 1992. Data on 12 are presented (three did not have a postmortem examination). The clinical diagnoses at referral for ECMO were as follows: persistent pulmonary hypertension of the newborn (six infants), primary congenital pneumonia (one infant), community acquired pneumonia (two infants), birth asphyxia (one infant), respiratory distress syndrome (one infant), and meconium aspiration syndrome (one infant). In our group, at necropsy, five had significant haemorrhage (three intracranial, one pulmonary, one pericardial and intraventricular). Three of five infants with evidence of haemorrhage also had signs of sepsis. Six infants had evidence at necropsy of systemic sepsis, five showed evidence of severe anoxic brain injury, and four infants had cerebellar haemorrhages. Three infants had evidence of myocardial ischaemia. It is difficult to discriminate between the relative influence of the primary diagnosis, the mode of treatment, and the severity of presentation in the genesis of this pathology. It is likely that the extent and severity of some of the findings represent a pathological progression that would have been interrupted by the death of the patient, had ECMO not been instituted.     

Twins with moyamoya disease

Moyamoya disease is a progressive disease which involves the internal carotid arteries and its branches bilaterally. The disease is reported both in adults and in children. Moyamoya disease is frequently seen in Japanese patients having certain human leucocyte antigen (HLA) haplotypes including HLA-Aw24, Bw46 and Bw54. Twin cases are rarely reported in the literature. We hereby present the first Turkish monozygotic twins with moyamoya disease whose HLA haplotypes are A2, A9, B21, Bw22, Bw4, Bw6, Cw3, and DR2, DR4, DRw52, DRw53, Dq7. The patients with advanced disease were given nifedipine and intravenous immunoglobulin (400mg/kg/d for 5 days). During the 11 months of follow-up, the patients were attack free.     

Ultrasonography in Patients with Suspected Acute Appendicitis

Background

To evaluate the usefulness and limitations of graded compression ultrasonography in the diagnosis of clinically equivocal cases of suspected acute appendicitis at the setting of mid zonal military hospital of India.

Methods

A prospective study, graded compression ultrasonography with self localization was carried out with 3.5 MHz convex, 5 MHz convex and 7.5 MHz linear transducers (Wipro GE) in 69 clinically equivocal suspected cases of acute appendicitis. With maximal compression the anteroposterior diameter of appendix was measured from outer to outer wall. The main criterion for diagnosing appendicitis was demonstration of a non compressible appendix with anteroposterior dimension of 7mm or more.

Result

Sonologically 36 (52%) cases were diagnosed as appendicitis. Anteroposterior outer diameter of inflamed appendices ranged from 7mm to 21mm (mean 10.5mm). 30 (83%) of 36 patients could accurately self localize the point of maximum tenderness. There were 01 false positive and 04 false negative cases. Sensitivity and specificity were 89.7% and 96.6% respectively. Positive and negative predictive values were 97.2% and 87.8% respectively. Alternative diagnoses were offered in 33 (47.8%) cases. Amongst these 33 cases, 14(42.4%) had abdominal pain of unknown origin. Gynaecologic, urologic and gastrointestinal aetiologies were established in 10(30.3%), 07(21.2%) and 02(6%) cases respectively.

Conclusion

Graded compression ultrasonography superadded with self localization is an accurate means of diagnosing/excluding appendicitis in clinically equivocal cases of acute appendicitis and it is of great value in establishing alternative diagnoses.Key Words: Ultrasonography, Acute appendicitis     

Outbreak of campylobacteriosis following pre-cooked sausage consumption

OBJECTIVES: A small outbreak of campylobacteriosis involving three cases was investigated in terms of Campylobacter types present in the suspect food (pre-cooked sausages) and clinical samples from the cases. METHOD: Foods and faecal samples from people involved in the incident, which occurred in Christchurch, New Zealand, were tested for the presence of Campylobacter and identification of the species made. Isolates were typed by Penner serotyping and macrorestriction analysis using pulsed-field gel electrophoresis (PFGE). Investigations were conducted as to whether the contamination was on the surface or the interior of the sausages. RESULTS: All isolates from food and faecal samples were identified as C. jejuni and were indistinguishable from one another by the typing methods employed. Only the surfaces of the sausages were contaminated. Three other isolates of an indistinguishable subtype were isolated from campylobacteriosis cases in Christchurch occurring over approximately the same period. CONCLUSIONS AND IMPLICATIONS: Given the rarity of the subtype isolated from the three family members and the three other cases, it is possible that the outbreak was larger than the initial investigation revealed. It is likely that the sausages were contaminated after they had been cooked by the retailer and were not reheated prior to consumption. This report illustrates the role of cross-contamination in an outbreak with an unusual food vehicle for campylobacteriosis. Physical separation of cooked and raw product is necessary to prevent recurrences of outbreaks similar to the one described here.     

Laparoscopic Management of Adnexal Masses

Retrospective study of 121 cases of adnexal masses which were managed laparoscopically was carried out. The aim of study was to evaluate the safety and effectiveness of laparoscopic management of adnexal masses. In 120 cases, procedure was completed safely with minimum morbidity. In one case laparotomy had to be done to complete the procedure. In 76 cases cystectomy was done, 26 required salpingo-oophorectomy and 19 required only salpingectomy. Histologic evaluation revealed 30 functional cysts, 36 endometriotic cysts, 11 dermoids, 9 serous cystadenomas, 3 mucinous cystadenomas, 11 parovarian cysts, 19 cases of hydrosalpinx and 2 cases of tuberculosis.Key Words: Adnexal mass, Laparoscopy, Ovarian cyst     

Do favorite movie stars influence adolescent smoking initiation?

OBJECTIVES: We sought to determine whether adolescents whose favorite movie stars smoke on-screen are at increased risk of tobacco use. METHODS: During interviews, adolescent never smokers taking part in the California Tobacco Survey nominated their favorite stars. We reviewed popular films released during 1994 through 1996 to determine whether stars smoked on-screen in at least 2 films. RESULTS: One third of never smokers nominated a star who smoked on-screen, which independently predicted later smoking risk (odds ratio [OR] = 1.36; 95% confidence interval [CI] = 1.02, 1.82). The effect was strong among girls (OR = 1.86; 95% CI = 1.26, 2.73). Among boys, there was no independent effect after control for receptivity to tobacco industry promotions. CONCLUSIONS: Public health efforts to reduce adolescent smoking must confront smoking in films as a tobacco marketing strategy.
