We hypothesize that, with elevated cerebral spinal fluid (CSF) pressure, cerebral micro-vascular obstruction and congestion may occur despite (subdural) large-vein pressures being normal. Smaller veins emptying into these larger, dura-enveloped veins are not immune to the compressive effects of elevated CSF pressure and a “Starling Resistor” mechanism might explain why elevated CSF pressures collapse these smaller veins. This small cerebral venous starling resistor compression mechanism may be the final common pathway for many patients suffering from increased CSF pressures and might also be an important contributor to impaired focal venous drainage presenting as a headache with normal venous sinus pressures.
Objective: To establish the cephalometric norms of ‘Zero meridian line’ and ‘Mew line’ to assess the sagittal discrepancy in the maxilla and mandible of subjects in the Central Gujarat population Materials and methods: The sample was screened from the records from the hospital. 100 individuals (50 males, 50 females) of the age group between 18-50 years, native of Central Gujarat, with acceptable pleasing profile, no skeletal asymmetry, normal Class I occlusion having ideal anterior bite, less than 2 mm crowding and no history of previous orthodontic treatment were selected for the study. Lateral cephalograph were taken in natural head position. The linear measurements between points of soft tissue pogonion to the Zero Meridian line (vertical line dropped from soft tissue nasion) and distance of Mew line (the biting edge of the upper front teeth to the tip of the nose) was taken on cephalograms. Result: Mean value for soft tissue pogonion to the Zero meridian line on cephalograms was 0.2 mm for female and 0.8 mm for male and mean value for Mew line on cephalograms was 39 mm for female and 42 mm for male subjects.Conclusion: Normal value for soft tissue pogonion to the Zero meridian line is 0.8 + 1.8 mm for males and 0.2 + 1.7 mm for females, and normal value for Mew line is 41.2 + 3.2 mm for male and 39.4 + 2.2 mm for female in Central Gujarat population. Values other than normal suggests skeletal sagittal discrepancy of maxilla and/or mandible, which is helpful in diagnosis and treatment planning.
With the discovery by Calghatgi (2013) that three common antibiotics (Abs) increased mitochondrial reactive oxygen (ROS) and lipid peroxide (LP) and depleted their natural absorbant glutathione led me to investigate further the potential impacts of these genotoxic substances on carcinogenesis. The range of impacts on mitochondria and cellular DNA varied by antibiotic to those consistent with known prior contributions to carcinogenesis. Specific cancers probably increased by these changes were HCC, RCC (KCC), CRC, cancer of the esophagus. Tumor suppressor gene mutations resulting from LP were noteworthy in this regard and mutations induced in CRC were consistent with those found in carcinogenesis of CRC. In addition depression of short chain fatty acids in microbiomes were found which depress the immune system increasing risk of all cancers. Many cancers were increased according to epidemiological studies linking Abs with elevated odds ratios, with one concern in particular, fatal breast cancer. The impact of loss of functionality of the mitochondria was also linked to depression of the citric acid cycle and therefore ATP which deflected metabolism to glycolysis, the Warburg mechanism also increasing risk of all cancers, favoured by cancer cells. In conclusion, some portion of many cancer types are probably increased in likelihood by number, type and frequency of Abs treatment and chronic residue exposure which varies from individual to individual. This led me to propose a three pronged carcinogenesis mechanism for Abs. 1. Cancer critical mutations 2. Immune depression 3. loss of mitochondrial functionality leading to Warburg effects. Damage to mitochondria were also noted by common pesticides tested in China and cancer associations were also found for many pesticides supporting a similar contributory etiology. Heart health concerns were raised by these findings because of the myriad mitochondria in the heart and because of long term reliability needs. Studies suggesting hearts were affected by Abs and pesticide exposure were presented. Because of their geographical ubiquitousness and the huge range of diseases associated with mitochondrial dysfunction, antibiotics and pesticides and bacteriocidal biocides are of concern for biodiversity and life in general. I propose research steps to evaluate Abs safety and suggest directions for further research and make suggestions on ways to ameliorate Abs toxicity.
Introduction: One of the major complications among COVID-19 patients include cardiac arrhythmias. Commonest arrhythmia is sinus tachycardia which is usually associated with palpitation causing discomfort to patients. In this study, we present a comparative study of use of Ivabradine vs. Carvedilol for sinus tachycardia in post-COVID-19 infected patients.
Method: 50 consecutive recovered COVID-19 patients with sinus tachycardia were included in this open labelled RCT. 25 patients received Ivabradine and remaining 25 received Carvedilol. Single therapy non-responders were treated with Ivabradine with Atorvastatin.
Results: The mean age of all patients is 48.8±7.66 years (Males 49.5 ± 7.21 years; Females 47.68 ± 8.23 years). The mean heart rate (MHR) of all patients is 125.52 ± 9.07/min (Males 125.67 ± 8.78/min; Females 125.26 ± 9.5/min). After five days of single drug therapy the mean drop in the heart rate was 35.04 ± 10.55/min (Males 34.41 ± 9.71/min; Females 36.05 ± 11.72/min), resulting in 27.88 ± 8.11% (Males 27.38 ± 7.56%; Females 28.69 ± 8.89%) reduction in MHR. Among the two groups, the Carvedilol group showed improvement of MHR in 14(56%) patients; whereas in Ivabradine group 18(72%) patients improved out of 25 patients each (p: 0.2385). In the Carvedilol group the MHR reduced from 128.6 ± 8.44 to 95.68 ± 10.63 (p < 0.001), which is statistically significant; similarly, the Ivabradine group showed a MHR from 122.44 ± 8.62 to 85.28 ± 10.52 (p < 0.001). The monotherapy therapy non-responders were treated with dual-therapy of (Ivabradine + Atorvastatin).
Discussion: Ivabradine is more effective in controlling heart rate compared to Carvedilol. Also, Ivabradine group scores very well in ‘patient-satisfaction’ with regards to symptom (palpitation) relief.
Conclusion: The COVID-19 sequelae of sinus tachycardia can be better controlled with Ivabradine when compared to Carvedilol.

The epidemics of heart failure and an aging population resulted in an exponential rise in the use of cardiac implantable devices (CIEDs) in developed countries. This is paralleled by the increased rate of complications such as system infection or malfunction. The higher number of complications, and longer patient life expectancies, are followed by an increase in the need for lead extractions.

Sitting: 2ed March teaching hospital, sebha Libya.
Materials and Methods: this was a prospective hospital base study of pediatric cases admitted to 2ed March teaching hospital during a period from March 2018 to February 2019. Pediatric cases were studied for the incidence of HBsAg and HCV Ab by ELISA, Rapid technique. The positive result was confirmed with line immuno-assay.
Results: the study showed positive HBsAg in 12 patients and HCV in 2 cases out 25 cases represented with acute hepatitis from a total of 1763 pediatric cases were submitted in this study, with incidence rate of 0.68% and 0.11% respectively.
Conclusion: the incidence of HBV and HCV are low in Sebha, therefore active program need to be applied to control the spread of infection among the population.
Non-alcoholic fatty liver disease (NAFLD) is a condition that is associated with cirrhosis and hepatocellular carcinoma, and is increasing in prevalence worldwide. Sleep disruptions are commonly seen in NAFLD, and the disease process is associated with sleep disorders, including obstructive sleep apnea, circadian rhythm disorders, and insufficient sleep. The intermittent hypoxia seen in obstructive sleep apnea may contribute to fibrotic changes in the liver.A major component of this linkage may be related to gut microbiome changes. One notable change is increase in Bacteroidetes/Firmicutes ratio, and decrease in flora that ferment fiber into anti-inflammatory short-chain fatty acids. Several therapeutic options exist for NAFLD that target both sleep and NAFLD, including non-pharmacological factors, such as lifestyle modification (mainly diet and exercise). Pharmacological options include melatonin, Vitamin E, thiazolidinediones, and fecal microbiota transplantation.Core tipThe pathogenesis of non-alcoholic fatty liver disease is closely tied to sleep and circadian rhythm abnormalities, through shared inflammatory pathways and altered metabolism. This review explores the pathogenesis of NAFLD in the context of sleep and circadian abnormalities. The associated inflammatory response is linked to changes in gut-microbiome interactions that contribute to the disease process. Understanding of this linkage has implications for various therapies for disease mitigation.

Quick and cost-effective recovery is foundational to high-quality training and good competition results in today’s sports. The aim of the research was to elucidate the effects of hand and massage chair massage on the biomechanical parameters of muscles of lower limbs and back, indicators of Pain Pressure Thresholds (PPT) and subjectively perceived fatigue. A total of 32 female recreational athletes (18 – 50 years old) were assigned to a hand massage, massage chair, or lying down the group. They were measured for muscle biomechanical properties (MyotonPro), PPT (Wagner Instruments) and subjectively perceived fatigue (VAS scale) before and after fatigue tests and treatment. The recovery procedure and subjective satisfaction with treatment were rated on a Likert scale. Changes in the median value of m. rectus femoris and m. gastrocnemius stiffness with treatment showed that hand massage could be more effective in reducing stiffness, as compared to chair massage. Hand massage may have benefits for recovery from physical exertion, but due to the individuality of subjects, detailed methodological studies are needed to evaluate the effects of massage chair vs. hand massage.
The Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome is the most severe form of congenital malformation of the inner female reproductive tract. It is diagnosed as such when the uterus, the upper vagina and optionally the Fallopian tubes are absent. It accounts for approximately 1 in 5000 live-born females and has been classified in two subtypes: type 1 in the presence of isolated uterovaginal aplasia and type 2 when associated in various combinations with extragenital malformations of the kidneys, skeleton, heart and auditory system. Most cases of MRKH syndrome are sporadic, although a significant number of many familial cases have been reported to date. Despite numerous studies, the genetics of the syndrome remains largely unknown and appears to be heterogeneous: chromosomal abnormalities and some candidate gene variants appear to be associated with a few cases; others have been suggested but not yet confirmed. To date, mainly the GREB1L gene appears to be a serious candidate. Among the remaining hypotheses, the controversial contribution of partial duplications of the SHOX gene is still puzzling, as the deficiency of this gene is a major cause of skeletal adysplasia syndromes. We have attempted to resolve this controversy in a study of 60 MRKH cases. Our results tend to show that SHOX duplications can be the origin of a genetic mechanism responsible for MRKH syndrome.
Primary umbilical cutaneous endometriosis is a rare umbilical endometrioma that affects women who are within the reproductive age group. It may be associated with infertility and severe dysmenorrhea and can be difficult to diagnosed in an asymptomatic patient.
We report a case of a 38-year-old nulliparous with seven years history of infertility and severe dysmenorrhea. Her hormonal profile assay and hysterosalpingogram results were normal while her husband semen analysis was also within normal range. She complained of monthly bleeding from a painful rubbery multilobate cutaneous nodule on the umbilicus of one year duration. She was diagnosed of cutaneous endometriosis. The diagnosis was confirmed histologically and she had surgical excision with good outcome.
