Spontaneous regression of a lumbar disc herniation: case report.

BACKGROUND: The phenomenon of the spontaneous disappearance of herniated discs is well known. CASE REPORT: The case of a 74-year-old male presenting with a large disc herniation at L5-S1, experiencing moderate sciatic pain, and having the straight-leg-raising test positive at 30 degrees is presented. The disc herniation was documented by computed tomography. He was treated conservatively with medication and physical therapy. One year later the patient was clinically reevaluated. He proved to be symptom-free and the follow-up computed tomography revealed spontaneous disappearance of the herniated disc fragment. The disc regression could have been due to dehydration, resorption as a result of an inflammatory reaction, or retraction into the intervertebral space. CONCLUSIONS: This report discusses the three aforementioned possible explanations and underlines the need for limiting surgical treatment strictly to patients with neurological deficits, severe unremitting leg pain despite conservative measures, and repeated time loss from work.     

Effects of orthodox religious fasting versus combined energy and time restricted eating on body weight,lipid concentrations and glycaemic profile

Abstract

For seven weeks, 37 overweight adults followed a hypocaloric diet based on Orthodox Fasting (OF). A hypocaloric, time restricted eating (TRE) plan (eating between 08:00 to 16:00?h, water fasting from 16:00 to 08:00?h) was followed by 23 Body Mass Index (BMI)-matched participants. Anthropometric, glycaemic and inflammation markers and serum lipids were assessed before and after the diets. Both OF and TRE groups demonstrated reductions in BMI (28.54?±?5.45 vs 27.20?±?5.10?kg/m², p?<?0.001 and 26.40?±?4.11 vs 25.81?±?3.78?kg/m² p?=?0.001, respectively). Following the intervention, the OF group presented lower concentrations of total and low-density lipoprotein-cholesterol, compared with the pre-fasting values (178.40?±?34.14 vs 197.17?±?34.30?mg/dl, p?<?0.001 and 105.89?±?28.08 vs 122.37?±?29.70?mg/dl, p?<?0.001, respectively). Neither group manifested significant differences in glycaemic and inflammatory parameters. Our findings suggest that OF has superior lipid lowering effects than the TRE pattern.     

Long-term outcome of pneumatic dilation in the treatment of achalasia

OBJECTIVE: Achalasia is a well-defined esophageal motor disorder for which pneumatic dilation is an established therapeutic method. Even though it has been used for several years, there are limited data on the long-term outcomes of patients treated with this procedure. Hence, we aimed to evaluate the long-term efficacy of pneumatic dilation to control the symptoms of achalasia. METHODS: The medical records of all patients treated in our unit for achalasia with pneumatic dilation were reviewed. We identified the long-term result of the initial procedure, the date of the first dilation, and the time interval between dilation and retreatment. RESULTS: Of 260 patients who were treated with pneumatic dilation, 153 (67 men, 86 women) were followed up for more than 5 yr. The mean follow-up period was 11.09 +/- 3.91 yr, and the success rate of the dilation was 75.8%. Among these patients, 35 (19 men, 16 women) had follow-up periods of more than 15 yr. The mean follow-up time of those patients was 16.56 +/- 1.09 yr, and the success rate was 51.4%. Kaplan-Meier survival analysis showed that, overall, 50% of patients develop recurring symptoms after 10.92 yr. CONCLUSIONS: Although 51.4% of patients continued to be in clinical remission more than 15 yr after the initial pneumatic dilation, the long-term success rate of pneumatic dilation seems to drop progressively with time.     

Clinical and psychological correlates of quality-of-life in polycystic ovary syndrome

OBJECTIVE: Polycystic ovary syndrome (PCOS) has been shown to cause a reduction in quality of life. This study examines the extent of different PCOS symptoms on quality-of-life, psychosocial well-being and sexual satisfaction. METHODS: Complete metabolic, hormonal, clinical and psychosocial data were obtained from a total of 120 women with PCOS. Patients were compared with 50 healthy women to establish reductions in quality-of-life and emotional well-being. In addition, the correlation between psychosocial variables and the major clinical PCOS features obesity (body mass index (BMI)), excessive body hair (hirsutism score), acne, hyperandrogenism (serum testosterone levels), disturbed insulin regulation (area under the insulin response curve and homeostasis model assessment of insulin resistance), menstrual cycle disturbances and infertility were analyzed. RESULTS: PCOS patients showed significant reductions in quality-of-life, increased psychological disturbances, and decreased sexual satisfaction when compared with healthy controls. BMI and hirsutism scores, but not the presence of acne, were associated with physical aspects of quality-of-life and sexual satisfaction. No clear effect of androgens or insulin resistance on psychosocial variables was detected. Similarly, the type of menstrual cycle disturbances or infertility had no impact on psychological well-being. CONCLUSION: In PCOS, changes in appearance, particularly obesity and hirsutism, reduce physical dimensions of quality-of-life and decrease sexual satisfaction. The role of biochemical, endocrine and metabolic parameters as well as menstrual irregularities and infertility appeared to be less important. Clinicians should pay attention to the psychosocial dimensions of PCOS on an individual basis, regardless of symptom severity or treatment response.     

A comparative study of postendoscopic sphincterotomy complications with various types of electrosurgical current in patients with choledocholithiasis

BACKGROUND: Whether the type of electrosurgical current used for endoscopic sphincterotomy influences the frequency of postsphincterotomy complications is unknown. METHODS: One hundred eighty-six patients with choledocholithiasis were prospectively randomized to undergo endoscopic sphincterotomy with pure cutting current (n = 62, Group A), blended current (n = 62, Group B), or pure cutting initially followed by blended current (n = 62, Group C). Serum concentrations of amylase and lipase were evaluated in all patients 12 and 24 hours after sphincterotomy. Clinical pancreatitis was classified as mild, moderate, or severe. Postsphincterotomy bleeding was defined as a decrease in hematocrit of greater than 5%. RESULTS: Serum concentrations of amylase and lipase were greater in Groups B and C at 12 and 24 hours after the procedure, as compared with Group A. Clinical mild pancreatitis occurred in 2 patients in Group A (3.2%), 8 in Group B (12.9%), and in 8 in Group C (12.9%). The differences were statistically significant for Group A compared with either Group B or Group C (p = 0.048). Postsphincterotomy bleeding occurred in 3 patients (1.6%), one in each group. CONCLUSION: The use of pure cutting electrosurgical current during endoscopic sphincterotomy in patients with choledocholithiasis is associated with a lesser degree of pancreatic enzyme elevation and lower frequency of pancreatitis, whereas bleeding is not increased compared with blended current. Changing from pure cutting to blended current after the first 3 to 5 mm of the incision is associated with an increased rate of complications compared to the use of pure cutting current for the entire sphincterotomy.     

Post‒cataract surgery endophthalmitis outbreak caused by multidrug-resistant Pseudomonas aeruginosa

In June 2010, a severe outbreak of 13 cases of post-cataract surgery endophthalmitis caused by multidrug-resistant Pseudomonas aeruginosa occurred. Pulse-field gel electrophoresis in eye isolates found 95% genetic similarity; however, extensive environmental and carriage investigation revealed no source of infection.     

Cytokine concentrations during the first days of life

OBJECTIVE: To evaluate the cytokine concentration patterns during the first 5 days of life by measuring serum concentrations of type-1 cytokines, like interleukin-2 (IL-2) and interferon-gamma (IFN-gamma) and type-2 cytokines, like IL-4, as well as the receptors of IL-2 (sIL-2R) and IL-4 (sIL-4R) during the early neonatal period. SUBJECTS AND METHODS: Forty-two healthy term neonates were included in the study. Cytokine concentrations were measured in umbilical cord, in the 1st and 5th day after birth and compared with those in serum of 30 healthy adults. RESULTS: IL-2 concentrations presented a decrease trend from umbilical cord to 5th day, while sIL-2R showed a significant elevation from umbilical cord to 5th day after birth. IL-4 concentrations did not differ significantly among umbilical cord, the 1st and the 5th day, while the sIL-4R showed the highest values in the 1st day after birth. Both IL-4 and sIL-4R concentrations in neonatal samples were elevated compared to adults. IFN-gamma concentrations increased significantly from umbilical cord to 5th day of life. CONCLUSION: Our findings indicate a dysregulation among IL-2, IL-4 and IFN-gamma concentrations during the 1st day after birth, favoring a more precocious expression of IL-2 and IL-4 against IFN-gamma that seems to be ameliorated in the end of the 1st week of life.
