ABSTRACT

Spontaneous coronary artery dissection (SCAD) is a non-traumatic non-iatrogenic coronary dissection. It's a frequent cause of acute coronary syndrome (ACS) in women without or with few traditional cardiovascular risk factors. We report an unusual case of multivessel SCAD in a middle-aged woman with successful medical management.

ABSTRACT

PURPOSE: Although one in three patients with diabetes in Western countries is over 70 years-old, geriatric syndromes and their relationship with survival remain seldom studied. The present aim of the GERODIAB study was to examine the evolution of geriatric disorders and their relationship with survival in older type 2 patients with diabetes with initial sufficient autonomy. METHODS: We performed a prospective, observational study over 5 years in patients with diabetes aged 70 years or above. A total of 987 consecutive type 2 patients with diabetes (mean age 77 years, range 70-94 years, 65.2% were 75 years and above, 52.1% women) were included from 56 French diabetic centres. Individual characteristics, diabetes parameters and geriatric parameters (autonomy, nutrition, cognitive alteration, depression, orthostatic hypotension, falls) were annually recorded. Survival was analysed using the Kaplan-Meier method and proportional hazards regression models. RESULTS: Institutional living, impaired activity and difficulties in instrumental daily activity, cognitive disorders, malnutrition, depression, orthostatic hypotension and hypoglycaemia strongly increased during the follow-up. Institutional living, impaired activity and difficulties in instrumental daily activity, cognitive disorders and hypoglycaemia were strongly associated with reduced survival, but not falls. In hazard ratio models, living in an institution (HR = 2.39; CI = 1.77-3.24; p < 0.0001) and impaired Activity of Daily Living scale score were the most significant and independent predictors of death (HR = 1.59; CI = 1.19-2.13; p = 0.0016), associated with HbA1c ≥ 70 mmol/mol (HR = 1.62; CI = 1.12-2.36; p = 0.011). CONCLUSION: Our findings show the considerable alteration of geriatric parameters and their relationship with decreased survival after a 5-year follow-up in type 2 patients with diabetes, independent of HbA1c and age. They, therefore, confirm the prognostic interest of using yearly geriatric markers in older diabetic patient management, especially the ADL, IADL and MMSE scales. Taking into account these prognostic parameters should contribute to target appropriate HbA1c goals. TRIAL REGISTRATION: Registered at clinicaltrials.gov (21/01/2011): NCT01282060.

ABSTRACT

Background: Level of fatigue is related to the metabolic energy available to tissues and cells, mainly through mitochondrial respiration, as well fatigue is the most common symptom of poorly functioning mitochondria. Hence, dysfunction of these organelles may be the cause of the fatigue seen in Chronic fatigue (CF). Placenta has been used for treatment of fatigue and various disease, moreover peptides has known protect mitochondrial viability, and alleviate fatigue. These properties of placenta and peptides may link with its effect on mitochondria; therefore, it is highly important to investigate the effectiveness of placenta peptide on fatigue and mitochondrial dysfunction. Methods: After administration of sheep placenta peptide (SPP) for 1 month, mice's were forced to swim till exhaustion for 90 min to induce chronic fatigue. Electron microscopic examination of skeletal muscle mitochondrial structure, tissue Malondialdehyde (MDA), mitochondrial SOD and serum inflammatory cytokines level were investigated in order to determine the potential effect of SPP on mitochondria during CF. Rat skeletal muscle (L6 cell) were also treated with different concentration of SPP to determine the effect of SPP on cell viability using Thiazoyl blue tetrazolium assay. Results: Our finding revealed that forced swimming induced fatigue model can cause mitochondrial damage through Reactive oxygen species (ROS) mediated lipid peroxidation and Tumor Necrosis factor alpha (TNF-α) elevation. Whereas SPP protected fatigue induced mitochondrial dysfunction through preventing ROS and TNF-α generation, by maintaining mitochondrial dynamic network and by increasing serum IL-6 level. Conclusion: SPP can protect damage in mitochondrial components which will allow proper functioning of mitochondria that will in turn inhibit progression of chronic fatigue. Therefore, SPP may represent a novel therapeutic advantage for preventing mitochondrial dysfunction in patients with chronic fatigue.

ABSTRACT

Inflammation is a normal immune response; but if the body's regulation of inflammation is dysfunctional, then it will have an adverse effect on the body. Although use of modern drugs for inflammation has a relieving effect, it is still unsatisfactory. Moreover, the emergence of drug-resistant strains and even new kinds of microorganisms is causing significant morbidity and mortality. Recently, more attention has been focused on herbal medicine to treat various diseases because of the ability of the herbs to affect multiple target signaling pathways and their multiple mechanisms of action. Thus, a large number of studies have reported on the anti-inflammatory and antimicrobial effects of the traditional Chinese herbs. Literature survey was performed by conducting systematic electronic search in PubMed, Science Direct, Google Scholar, and in books. This review has listed 11 heat-clearing Chinese herbs (HCCHs) including Scutellaria baicalensis ( Huáng Qín), Coptis chinensis ( Huáng Lián), Flos Lonicerae ( Jin Yín Hua), Forsythia suspensa ( Lián Qiào), Isatidis Folium ( Dà Qin Yè), Radix Isatidis ( Bǎn Lán Gen), Viola yedoensis ( Zǐ Hua Dì Din), Pulsatilla Radix ( Bái Tóu Wen), Andrographis paniculata ( Chuan Xin Lián), Houttuynia cordata ( Yú Xing Cǎo), and Patrinia Herba ( Bài Jiàn Cǎo), which have anti-inflammatory and antimicrobial effects, and has described their effects through different mechanisms of action and multiple targets. Their ability to affect multiple target signaling pathways and their potential mechanisms of action contributing to their anti-inflammatory and antimicrobial activity may be related to their action of removing heat and counteracting toxicity. Further studies are needed on the collection of HCCHs to know the detailed mechanism of action of herbs in this group for the assessment of effective drug.

ABSTRACT

INTRODUCTION: Congenital nasal pyriform aperture stenosis (CNPAS) is a rare and an unusual cause of airway obstruction in newborns. OBSERVATION: We report the case of a female neonate delivered by C-section at 39 weeks of amenorrhea for hydramnios and macrosomia. She presented with mandibular retrognathia, nasal saddling, submucous cleft palate, and loud mouth respiration. She presented with cyanosis every time feeding was attempted. CT revealed permeable choans with a single central incisor and nasal pyriform aperture stenosis. Nasal respiration returned to normal progressively after 56 days of hospitalization. The status was unchanged at 5 months. DISCUSSION: CNPAS is a rare cause of congenital nasal obstruction. It is sometimes associated to a median incisor syndrome. The diagnosis should be made as early as possible for an optimal management. Cyanosis and swallowing disorders may be lethal consequences. Associated abnormalities should be screened for with TDM or MRI. The treatment depends on the severity and may be surgical for a severe stenosis. The prognosis is good if no severe malformation or mental retardation is associated.

ABSTRACT

BACKGROUND: Meconium aspiration syndrome is a disease of the newborn mature or post mature. The acute pulmonary consequences can be extremely severe. In the few studies of the long-term pulmonary sequelae, it seems that certain children surviving meconium aspiration syndrome keep an obstructive syndrome. The aim of our study was to assess long term respiratory residual damage from meconium aspiration syndrome. METHODS: During a seven-year period going from 1994 to 2000, we reviewed the files of children hospitalized in neonatology department of Sfax for meconium aspiration syndrome. The children who were convoked (group M: n=27), underwent spirometry, followed by an exercise stress. An age matched control group (group C: n=23) of healthy children was investigated in the same way. RESULTS: The group M comprised 15 boys and 12 girls aged four to 11, an average of 7+/-1.9 years. With the study of the respiratory function, we did not find an obstructive syndrome. Spirometry revealed a total pulmonary capacity in an average of 133+/-55.65% of theoretical (group M) versus 105.5+/-27.96% of theoretical (group C) (P<0,01), testifying to alveolar hyperinflation. Spirometry fulfilled 5, 10 and 15 min after exercise showed a FEV1 reduction of respectively 8.5 versus 2 (P<0.05); 9.5 versus 3 (P<0.01) and 10.5 versus 4 (P<0.05). CONCLUSION: Children surviving meconium aspiration syndrome tend to develop alveolar hyperinflation and airway hyperreactivity to exercise.

ABSTRACT

Renal tubular dysgenesis (RTD) is a rare and severe nephropathy characterized by persistent fetal anuria leading to oligohydramnios with the Potter sequence, and perinatal death. The diagnosis is based on the histological finding of absence or paucity of proximal tubules. A consanguineous family is described in which 2 siblings, born after pregnancies complicated by oligohydramnios were affected with RTD. Patients were small for gestational age at birth. The first patient died after a few hours, the second after a few days of life, with persistent anuria unresponsive to treatment. Histologically, there was marked reduction in the number of proximal tubule sections and no renin was detected by immunohistochemistry. An homozygous mutation of the gene encoding renin was identified in both patients. This study underlines the interest of the histological examination of the kidney for the diagnostic of RTD in anuric fetuses and newborns, and the possibility of mutation analysis of RAS genes for genetic counselling and early prenatal diagnosis.

ABSTRACT

OBJECTIVE: Opioids are routinely omitted at the induction of general anesthesia for Caesarean delivery because of the risks of respiratory neonatal depression. The short-acting opioid remifentanil may afford advantages at the induction and surgical stimulation, without subsequent neonatal depression. PATIENTS AND METHODS: In this double-blinded study, 40 at term women undergoing elective Caesarean section and requiring general anaesthesia were allocated randomly to receive either remifentanil (0,5 microg/kg) at the induction of anaesthesia (G1, n=20) or placebo (G2, n=20). Induction of anaesthesia was performed with propofol 2 mg/kg and succinylcholine 1 mg/kg. Anaesthesia was maintained with nitrous oxide in oxygen (50/50%, v/v), propofol (100 microg/kg/min), remifentanil (0.2 microg/kg/min) and atracurium. Neonates were assessed by using Apgar scores, possible respiratory depression, with or without ventilation in the mask or intubation and umbilical cord blood gas (artery: UA and vein: UV). Values are expressed as mean values +/-SD. Pearson's Chi squared and t-test were used for statistical analysis P<0.05 was considered significant. RESULTS: Maternal systolic pressure, mean pressure and heart rate were significantly higher in G1 at induction. Apgar scores, heart and respiratory rate were similar between groups. Seven episodes of respiratory depressions were noted (3 in G1, 4 in G2). Five neonates required only brief assisted ventilation by face-mask (2 in G1, 3 in G2). CONCLUSION: Remifentanil (0.5 microg/kg) at the induction of anaesthesia in elective Caesarean section under general anaesthesia can be used without subsequent neonatal depression. However, we believe that further research is necessary to extrapolate these results to a pregnancy carrying an acutely distressed foetus.

ABSTRACT

There have been few reports of neonatal ischemic necrosis of the testis without torsion of the spermatic cord, which may be caused either by compression in utero or by transient torsion of the spermatic cord resolving spontaneously before surgery. The patient reported herein developed an inflammatory swelling of the right scrotum and an ecchymotic plaque over the left thigh at four days of age. Ischemic necrosis of the right testis without torsion was found upon surgery. When the patient was ten days of age, he developed an inflammatory swelling in the left scrotum; ischemic necrosis of the left testis without torsion was again found upon surgery. Thrombosis of the spermatic vessels was suspected. Postoperatively, ecchymotic and necrotic skin lesions developed, followed by pulmonary embolism and cerebral thrombosis. Outcome was fatal. Hematologic tests in the neonate and his parents established the diagnosis of inherited antithrombin III deficiency. Ischemic necrosis of the testes was thus probably due to hypercoagulability. No similar cases have been reported to date.

ABSTRACT

In a Tunisian hospital 27 babies, including 12 who were premature, in a single intensive care unit suffered acute gastroenteritis in the period from January to May 1988. The mean age at the onset of gastroenteritis was 8.4 days; nine babies died. Salmonella wien was isolated from stools (all babies) and blood (4 babies). It was also isolated from the stools of one nurse and from a mattress. Twelve of the babies had received cefotaxime, which was successfully replaced by oral colimycin. The outbreak was stopped by the implementation of infection control measures. All isolates of Salmonella wien were of the same biotype, and had the same antibiotic resistance pattern (third generation cephalosporins, monobactams, aminoglycosides, chloramphenicol, trimethoprim and sulphonamides) and plasmid DNA restriction pattern. The isolates were all susceptible to a combination of cefotaxime and clavulanic acid (a beta-lactamase inhibitor), which displayed synergy, suggesting the presence of a beta-lactamase (geometric mean MICs 11.24 micrograms/ml for cefotaxime alone and 0.24 micrograms/ml in combination with 0.1 micrograms/ml potassium clavulanate). All isolates produced TEM-1 and SHV-2 beta-lactamase which was not transferable to Escherichia coli by conjugation. The presence of the SHV-2 enzyme in Salmonella wien may allow it to adapt to newer beta-lactams which is a cause for concern in this hospital.

ABSTRACT

The results of a retrospective study of 2,108 accidents in 0-14-year-old children are presented, recorded over a 1-year period at the Sfax Medical Centre, Tunisia. The average age of the children was 6 years 4 months. Our results show that 85% of the accidents were domestic (traumatisms 72%; poisoning 11%). The frequency and gravity of poisoning due to scorpion bites is emphasized: it represented 7% of the accidents, 35% of mortality due to accidental causes and a lethality rate of 10%. The total mortality rate due to accidental causes was 2%. Five per cent of the patient population had sequelae. Factors influencing the nature and gravity of the accident have been analysed and some recommendations have been made regarding prevention of accidents in children.
