Synthesis,in vivo and in silico evaluation of novel 2,3-dihydroquinazolin-4(1H)-one derivatives as potential anticonvulsant agents

In light of the pharmacophoric structural requirements for achieving anticonvulsant activity, a series of N-(1-methyl-4-oxo-2-un/substituted-1,2-dihydroquinazolin-3[4H]-yl)benzamide (4a-g) and N-(1-methyl-4-oxo-2-un/substituted-1,2-dihydroquinazolin-3[4H]-yl)-2-phenylacetamide (4h-n) derivatives were synthesized in two steps starting from the reaction of N-methyl isatoic anhydride with the appropriate hydrazide and followed by condensation with the appropriate aldehyde. The anticonvulsant activities of the synthesized compounds were evaluated according to the anticonvulsant drug development (ADD) programme protocol. Among the synthesized compounds, 4n showed promising activity in both the maximal electroshock (MES) and pentylenetetrazole (PTZ) tests with median effective dose (ED₅₀) values of 40.7 and 6 mg/kg, respectively. The six most promising derivatives, 4b , 4a , 4c , 4f , 4j , and 4i , showed very low ED₅₀ values in the PTZ test (3.1, 4.96, 8.68, 9.89, 12, and 13.53 mg/kg, respectively). All the tested compounds showed no to low neurotoxicity in the rotarod test with a wide therapeutic index. Docking studies of compound 4n suggested that GABA_A binding could be the mechanism of action of these derivatives. The in silico drug likeliness parameters indicated that none of the designed compounds violate Lipinski's rule of five and that they are able to cross the blood–brain barrier.

Immunoglobulin replacement therapy contribution in agammaglobulinemia: 10 case reports]

Intravenous immunoglobulin (Ig IV) has been used for many years in the treatment of primary antibody deficiencies. We performed a retrospective study of the clinical features and outcome of agammaglobulinemia children who received prolonged Ig IV infusions. PATIENTS AND METHODS: Ten children, 9 male et 1 female, with agammaglobulinemia diagnosis were studied for the clinical manifestations before and during the Ig IV replacement therapy. Serum Ig levels were quantified by nephelometry. Circulating B ant T cells were counted by immunofluorescence labeling by monoclonal antibodies. T-cell functions were assessed by using mitogen and antigen -induced T-cell proliferation assays in vitro. Patients clinical status was evaluated respectively, before initiation and at every moment (when patients had an infection) of the replacement therapy. RESULTS: Ig IV therapy was performed for 866 cumulated months, median 108 months. The median Ig IV doses administered to the 10 patients was 500 mg/kg/month. Residual serum IgG mean level was 3,9 g/L. All patients had 99 bacterial infections/year before Ig IV, mainly respiratory tract infections (48,5%), and 4 patients had bronchiectasis before Ig replacement therapy. The number of infection/year fall to 25 during IgIV replacement, and the infection/patient/year rate decreases significantly. One patient developed an Echovirus 27 meningoencephalitis during this treatment. CONCLUSION: Ig IV therapy with residual IgG mean level of 3,9 g/l reduced significantly the rate of bacterial infections. The use of specific antibiotherapy and respiratory kinesitherapy led to a lower rate of respiratory tract infections, and the stabilisation of the bronchiectasis. However this intravenous replacement therapy does not protect against viral meningoencephalitis.     

Rapid sequence treatment of advanced squamous cell carcinoma of the upper aerodigestive tract: A pilot study

A review of the literature suggested that prolonged treatment time may lessen the probability of cure for patients with advanced squamous cell carcinoma of the upper aerodigestive tract. To shorten treatment time, rapid sequence treatment (RST) was devised in which chemotherapy, surgery, and irrada-tion were administered in a total treatment time of 8 weeks. Twelve patients were treated and followed 3 years or longer. Medical complications were minor. Osteonecrosis occurred in each of the first five patients and was the only major complication of the protocol. Surgical techniques were modified, and no additional patient developed osteonecrosis. No patient developed local or regional recurrence. Two patients developed distant metastases and three other patients developed second primaries. Absolute survival was 50%. Rapid sequence treatment is an aggressive and potentially hazardous protocol that yielded encouraging results in this pilot study.     

Raising awareness and providing free screening improves cervical cancer screening among economically disadvantaged Lebanese/Armenian women.

Women need to practice cervical screening regularly to reduce morbidity and mortality. The purpose of this study was to examine the impact of an intervention program on knowledge, attitude, and practice of cervical screening in the population of Lebanese/Armenian women. The design was a cross-sectional, quasi-experimental posttest survey following a year long intervention program. The sample included 176 women, who were members of the Armenian Relief Cross in Lebanon. Interventions consisted of educational classes, media messages, and free screening. The instrument was a self-administered questionnaire. Knowledge of women with intervention was higher (p > .05) and practice rate increased between intervention and comparison groups. No difference in attitude was noted. The study was successful in raising awareness and increasing screening in the sample. It is recommended to continue helping women to overcome barriers for cervical screening.     

Pakistan’s Response to COVID-19: Overcoming National and International Hypes to Fight the Pandemic

The COVID-19 outbreak started as pneumonia in December 2019 in Wuhan, China. The subsequent pandemic was declared as the sixth public health emergency of international concern on January 30, 2020, by the World Health Organization. Pakistan could be a potential hotspot for COVID-19 owing to its high population of 204.65 million and its struggling health care and economic systems. Pakistan was able to tackle the challenge with relatively mild repercussions. The present analysis has been conducted to highlight the situation of the disease in Pakistan in 2020 and the measures taken by various stakeholders coupled with support from the community to abate the risk of catastrophic spread of the virus.     

An Overview of the Treatment Options Used for the Management of COVID-19 in Pakistan: Retrospective Observational Study

BackgroundSince the first reports of COVID-19 infection, the foremost requirement has been to identify a treatment regimen that not only fights the causative agent but also controls the associated complications of the infection. Due to the time-consuming process of drug discovery, physicians have used readily available drugs and therapies for treatment of infections to minimize the death toll.ObjectiveThe aim of this study is to provide a snapshot analysis of the major drugs used in a cohort of 1562 Pakistani patients during the period from May to July 2020, when the first wave of COVID-19 peaked in Pakistan.MethodsA retrospective observational study was performed to provide an overview of the major drugs used in a cohort of 1562 patients with COVID-19 admitted to the four major tertiary-care hospitals in the Rawalpindi-Islamabad region of Pakistan during the peak of the first wave of COVID-19 in the country (May-July 2020).ResultsAntibiotics were the most common choice out of all the therapies employed, and they were used as first line of treatment for COVID-19. Azithromycin was the most prescribed drug for treatment. No monthly trend was observed in the choice of antibiotics, and these drugs appeared to be a random but favored choice throughout the months of the study. It was also noted that even antibiotics used for multidrug resistant infections were prescribed irrespective of the severity or progression of the infection. The results of the analysis are alarming, as this approach may lead to antibiotic resistance and complications in immunocompromised patients with COVID-19. A total of 1562 patients (1064 male, 68.1%, and 498 female, 31.9%) with a mean age of 47.35 years (SD 17.03) were included in the study. The highest frequency of patient hospitalizations occurred in June (846/1562, 54.2%).ConclusionsGuidelines for a targeted treatment regime are needed to control related complications and to limit the misuse of antibiotics in the management of COVID-19.     

Detection and molecular typing of human papillomaviruses: prevalence of cervical infection in the Tunisian central region

There are compelling molecular and epidemiological data which indicate that infection with certain genital human papillomaviruses (HPVs), such as HPV 16 and HPV 18, has a critical role in initial changes that lead to cervical and probably other anogenital cancers. These observations prompted us to investigate the prevalence of cervical infection with genital human papillomaviruses in Tunisia. We used the polymerase chain reaction (PCR) to detect and type HPV DNA. The prevalence of HPV infection in a population of 106 Tunisian women recruited at the Offices Nationaux de la Famille et de Population (ONFP) was 13.6%. Molecular HPV typing indicated a high prevalence of HPV at high oncogenic risk; Our results indicate that the infection with genital human papillomaviruses is frequent in the Tunisian population.
