Furthermore, studies have also identified association between COVID-19 fatalities and the latitude. The intensity of sunlight is highest near the equator, and therefore populations in these regions with more regular exposure to sunlight are less susceptible to vitamin D deficiency. This article has analyzed the potential impact of sunlight in reducing SARS-CoV-2 transmissibility, morbidity, and mortality. It is evident that there exists an interesting link between sunlight exposure, latitude, and vitamin D status with COVID-19 incidence, fatality and recovery rates that requires further investigation.Head and neck paragangliomas are rare vascular tumors derived from the paraganglionic system, located at the carotid body, jugular vein, tympanic cavity and vagal nerve. From 2010 to 2020, a cohort of 26 patients divided in two groups, 15 with cervical paragangliomas and 11 with temporal bone paragangliomas, was reviewed by analysing the medical history, the epidemiological and clinical parameters, the imaging results and classification, the modality of treatment and outcome. Cervical paragangliomas present as firm and pulsatile mass with the characteristic aspect of "salt and pepper" on MRI T1 weighted sequences. The most common type on Shamblin classification was the type II. Total surgical resection was performed in 93,33% of cases. The sensitivity of MRI in the diagnosis of vagal paragangliomas was up to 75%, with a specificity of 90,91% and the correlation of the MRI results and the findings of surgical exploration is significant with p ⩽ 0.02. Temporal bone paragangliomas appear as pulsatile mass behind the tympanic membrane, causing variable hearing loss in 90,90% of the cases. The facial nerve is the most frequently affected cranial nerve, in 36,36% of the cases. The main type according to FISH classification is the type B. Embolization was performed in all type C tumors. Surgery was the first line treatment while the inoperable patients were considered for radiotherapy. The aim of this study is to report the main clinical features of head and neck paragangliomas, the imaging tools and findings evaluating their sensitivity and specificity and the treatment protocol and outcome.The tamponade leads to an increase in intrapericardial pressure, which impairs the diastolic filling of the ventricles and reduces ejection. However, the association with pulmonary arterial hypertension, which in turn leads to an intracardiac hyper-pressure, constitutes a compensatory mechanism. We report the case of a 23 year old patient followed for anemia due to martial deficiency for 2 years, who consulted us with right heart failure evolving for 5 months, a hemoptoic cough and chest tightness. The entire workup revealed a pericardial and pleural tamponade of tuberculous origin associated with a pulmonary embolism evaluated at 15% according to the Qanadli score. After stabilization of her hemodynamic state, the patient was put on anti-bacillary and anticoagulant treatment with a good improvement of her cardiopulmonary state. She was discharged after 1 month (satisfactory check-up), regularly followed up in outpatient clinic with check-up of hemostasis and cardiac echography every 2 weeks. She was declared cured of her tuberculosis after 6 months of treatment. There was no recurrence after two years of follow-up. The combination of tamponade and pulmonary hypertension is synergistic in that it improves the patient's prognosis.
  The aim of the current study was to examine the following hypotheses 1. Mothers who breastfeed their infants from 2 to 12 months of age or who use a mixed-feeding method after birth will demonstrate greater attachment toward their infants than mothers who only formula-feed their infants, as measured by the Maternal Attachment Inventory (MAI). 2. A difference in maternal attachment levels will be observed between mothers who exclusively formula-feed their infants and those who exclusively breastfeed their infants from 2 to 12 months of age, as measured by the MAI inventory, controlling for infant temperament.
 
  A cross-sectional, descriptive, comparative method was applied in different healthcare centers in Jordan from May 2016 to August 2016 in which the MAI inventory was employed to assess 258 Arabic-speaking mothers. One-way analysis of variance was used to detect the differences in maternal attachment between mothers using different feeding methods.
 
  The findings showed significant differences in maternal attachment between exclusive breastfeeding and exclusive formula-feeding mothers, and mixed-feeding mothers at 2 months (F=24.36, P<.01). Moreover, there was a statistically significant difference in maternal attachment between the breastfeeding and the formula-feeding group (F=24.358, p<.05) after holding temperament constant.
 
  The results of this current study may help to clarify one role of breastfeeding in shaping a mother's attachment. Healthcare providers need to understand the influences of these variables on maternal attachment and attachment to empower young mothers and counsel them appropriately.

Supravesical hernia is an exceptional form of hernia that is often diagnosed intraoperatively. The abdominal CT scan performed in the emergency guides the preoperative diagnosis. Our work concerns a patient admitted to the visceral surgical department of the university hospital ibn Rochd of Casablanca for an occlusion dating back to 05 days, the abdmonial x-ray objectified hydro-aerial levels in the small intestine, and the CT scan found an invagination at the left fossa iliaca associated with a double hernia internal supravesical and left inguinal. The patient was then operated after conditioning and the diagnosis of an internal supravesical hernia was retained per operatively.  https://www.selleckchem.com/products/isa-2011b.html  Internal supravesical hernia is a very rare cause of acute intestinal occlusion and is often diagnosed at the time of surgical exploration.
