OBJECTIVE
This study aimed to determine whether adjunctive therapy with magnesium sulfate is more effective than diazepam alone in reducing mortality and morbidity rates among adult patients with tetanus admitted to Mariano Marcos Memorial Hospital and Medical Center (MMMH & MC) from January 1, 2012, to January 1, 2022.
METHODSRetrospective cohort study using chart review and descriptive statistics. included patients admitted at East Avenue Medical Center for DFU. The primary endpoint was major amputation of the lower extremities. Data were analyzed using Receiver Operating Characteristic (ROC) analysis and logistic regression.
RESULTSA total of 51 patients were included in the study, with 17 patients in the adjunct magnesium sulfate group and 34 patients in the diazepam group. Based on the results of this study, at a 95% confidence interval, ICU stay was significantly longer in the magnesium sulfate group compared to the diazepam group, along with an increased average hospital stay. There was no significant difference in patient mortality in terms of treatment, age, severity, ICU stay, or duration of mechanical ventilation.
CONCLUSIONThe use of magnesium sulfate as an adjunct treatment for tetanus is not superior to standard stand-alone diazepam, regardless of severity. Magnesium sulfate use is associated with a longer overall hospital stay. Lastly, hospital-acquired pneumonia and aspiration pneumonia significantly increase the risk of mortality among patients with tetanus, regardless of age, treatment, or severity.

Objective To explore the inhibitory effects and mechanisms of benzodiazepines on Helicobacter pylori (Hp).Methods The Hp international standard strain ATCC43504 was treated with benzodiazepines diazepam,midazolam,and remimazolam,respectively.The treatments with amoxicillin and clarithromycin were taken as the positive controls,and that with water for injection as the negative control.The inhibition zone of each drug was measured by the disk diffusion method.The minimum inhibitory concentration(MIC)and minimum bactericidal concentration(MBC)of each drug against Hp were determined.Hp suspension was configured and treated with diazepam and midazolam,respectively.The bacterial suspension without drug added was used as the control group.The concentration of K+ in each bacterial suspension was measured by an automatic biochemical analyzer before drug intervention(T0)and 1(T1),2(T2),3(T3),4(T4),5(T5),6(T6),and 7 h(T7)after intervention.Hp urease was extracted and treated with 1/2 MIC diazepam,1 MIC diazepam,2 MIC diazepam,1/2 MIC midazolam,1 MIC midazolam,2 MIC midazolam,1 mg/ml acetohydroxamic acid,and water for injection,respectively.The time required for the rise from pH 6.8 to pH 7.7 in each group was determined by the phenol red coloring method.Results The inhibition zones of diazepam,midazolam,remimazolam,amoxicillin,clarithromycin,and water for injection against Hp were 52.3,42.7,6.0,72.3,60.8,and 6.0 mm,respectively.Diazepam and midazolam showed the MIC of 12.5 μg/ml and 25.0 μg/ml and the MBC of 25 μg/ml and 50 μg/ml,respectively,to Hp.The concentrations of K+ in the diazepam,midazolam,and control groups increased during T1-T7 compared with those at T0(all P<0.01).The concentration of K+ in diazepam and midazolam groups during T1-T4 was higher than that in the control group(all P<0.01).The time of inhibiting urease activity in the 1/2 MIC diazepam,1 MIC diazepam,2 MIC diazepam,1/2 MIC midazolam,1 MIC midazolam,and 2 MIC midazolam groups was(39.86±5.11),(36.52±6.65),(38.58±4.83),(39.25±6.19),(36.36±4.61),and(35.81±6.18)min,respectively,which were shorter than that in the acetohydroxamic acid group(all P<0.01)and had no significance differences from that in the water for injection group(all P>0.05).Conclusion Diazepam and midazolam exerted inhibitory effects on Hp,which may be related to the cleavage of Hp cells rather than inhibiting urease.

INTRODUCTION:
Misuse of prescription medicines and the harms associated with such use are growing threats across the world. There is currently, however, limited data on the extent of prescription medicine misuse in Singapore and whether this is a current threat in the country.
METHODS:
An online survey, limited to 1,000 individuals (aged 21 years and over) who were residents in Singapore, was administered through a survey panel company in September 2015. The survey collected information on participant demographics, and their awareness, self-reported lifetime and past-year misuse of commonly available prescription medicines in Singapore as well as the use of a range of recreational drugs and novel psychoactive substances (NPS).
RESULTS:
Lifetime (6.7%) and past-year (4.8%) misuse of any prescription medicine was comparable to lifetime (6.0%) and past-year (3.0%) use of any recreational drugs/NPS. The top five prescription medicines for lifetime misuse were: diazepam (2.7%); codeine (2.3%); dhasedyl (promethazine, codeine and ephedrine; 1.6%); panadeine (paracetamol and codeine; 1.5%); and methylphenidate (1.2%). The top five drugs for past-year misuse were: diazepam (1.6%); codeine (0.9%); panadeine (0.7%); alprazolam (0.6%); baclofen (0.6%); and gabapentin (0.6%).
CONCLUSION
Misuse of prescription medicine in Singapore was common, with prevalence comparable to the use of recreational drugs/NPS. A common source for misused drugs was physicians. Further studies are required to determine whether this is more widespread in Singapore and establish the different forms of drug diversion, so that appropriate prevention strategies can be implemented.

Regulator of calcineurin 1 (RCAN1) can be induced by an intracellular calcium increase and oxidative stress, which are characteristic features of temporal lobe epilepsy. Thus, we investigated the spatiotemporal expression and cellular localization of RCAN1 protein and mRNA in the mouse hippocampus after pilocarpine-induced status epilepticus (SE). Male C57BL/6 mice were given pilocarpine hydrochloride (280 mg/kg, i.p.) and allowed to develop 2 h of SE. Then the animals were given diazepam (10 mg/kg, i.p.) to stop the seizures and sacrificed at 1, 3, 7, 14, or 28 day after SE. Cresyl violet staining showed that pilocarpine-induced SE resulted in cell death in the CA1 and CA3 subfields of the hippocampus from 3 day after SE. RCAN1 immunoreactivity showed that RCAN1 was mainly expressed in neurons in the shammanipulated hippocampi. At 1 day after SE, RCAN1 expression became detected in hippocampal neuropils. However, RCAN1 signals were markedly enhanced in cells with stellate morphology at 3 and 7 day after SE, which were confirmed to be reactive astrocytes, but not microglia by double immunofluorescence. In addition, real-time reverse transcriptase–polymerase chain reaction showed a significant upregulation of RCAN1 isoform 4 (RCAN1-4) mRNA in the SE-induced hippocampi. Finally, in situ hybridization with immunohistochemistry revealed astrocytic expression of RCAN1-4 after SE. These results demonstrate astrocytic upregulation of RCAN1 and RCAN1-4 in the mouse hippocampus in the acute and subacute phases of epileptogenesis, providing foundational information for the potential role of RCAN1 in reactive astrocytes during epileptogenesis.

Sinomenium acutum has been long used in the preparations of traditional medicine in Japan, China and Korea for the treatment of various disorders including rheumatism, fever, pulmonary diseases and mood disorders. Recently, it was reported that Sinomenium acutum, has sedative and anxiolytic effects mediated by GABA-ergic systems. These experiments were performed to investigate whether sinomenine (SIN), an alkaloid derived from Sinomenium acutum enhances pentobarbital-induced sleep via γ-aminobutyric acid (GABA)-ergic systems, and modulates sleep architecture in mice. Oral administration of SIN (40 mg/kg) markedly reduced spontaneous locomotor activity, similar to diazepam (a benzodiazepine agonist) in mice. SIN shortened sleep latency, and increased total sleep time in a dose-dependent manner when co-administrated with pentobarbital (42 mg/kg, i.p.). SIN also increased the number of sleeping mice and total sleep time by concomitant administration with the sub-hypnotic dosage of pentobarbital (28 mg/kg, i.p.). SIN reduced the number of sleep-wake cycles, and increased total sleep time and non-rapid eye movement (NREM) sleep. In addition, SIN also increased chloride influx in the primary cultured hypothalamic neuronal cells. Furthermore, protein overexpression of glutamic acid decarboxylase (GAD(65/67)) and GABA(A) receptor subunits by western blot were found, being activated by SIN. In conclusion, SIN augments pentobarbital-induced sleeping behaviors through GABA(A)-ergic systems, and increased NREM sleep. It could be a candidate for the treatment of insomnia.

Neuropathic pain is usually managed pharmacologically, rather than with botulinum toxin type A (BTX-A). However, medications commonly fail to relieve pain effectively or have intolerable side effects. We present the case of a 62-year-old man diagnosed with an intracranial chondrosarcoma, which was removed surgically and treated with radiation therapy. He suffered from neuropathic pain despite combined pharmacological therapy with gabapentin, amitriptyline, tramadol, diazepam, and duloxetine because of adverse effects. BTX-A (100 units) was injected subcutaneously in the most painful area in the posterior left thigh. Immediately after the injection, his pain decreased significantly from 6/10 to 2/10 on a visual analogue scale. Pain relief lasted for 12 weeks. This case report describes intractable neuropathic pain caused by a brain tumor that was treated with subcutaneous BTX-A, which is a useful addition for the management of neuropathic pain related to a brain tumor.

We developed a simple, sensitive, and effective ultra-performance liquid chromatography/tandem mass spectrometry (HPLC-MS/MS) method with an electrospray ionization (ESI) interface in multiple reaction monitoring (MRM) and positive ion modes to determine diazepam concentrations in human plasma using voriconazole as an internal standard (IS). Diazepam and IS were detected at transition 285.2→193.1 and 350.2→127.1, respectively. After liquid-liquid extraction (LLE) using 1.2 ml of ethyl acetate:n-hexane (80:20, v/v), diazepam and IS were eluted on a Phenomenex Cadenza CD-C18 column (150 × 3.0 mm, 3 µm) with an isocratic mobile phase (10 mM ammonium acetate in water:methanol [5:95, v/v]) at a flow rate of 0.4 mL/min. The peak retention time was 2.32 min for diazepam and 2.01 min for IS, respectively. The lower limit of quantitation (LLOQ) was 0.5 ng/mL (S/N > 10) using 50 µL of plasma, and no interferences were observed in chromatograms. Our analytical method was fully validated and successfully applied to a bioequivalence study of two formulations of diazepam in healthy Korean volunteers.

9.A study on the knowledge and management practices on hypertension in pregnancy among midwives in the different public health centers of Cebu City.
Maria Carlyn RODRIGUES-DE VERA ; Geraldine Isabella B UYHENG
Philippine Journal of Obstetrics and Gynecology 2017;41(6):1-15
ABSTRACT:
BACKGROUND: The Millennium Development Goal (MDG) for 2015 has a target MMR of 52/100,000 live births but this goal been difficult to achieve. In the Philippines, 11 mothers die everyday from pregnancy related complications, a bulk contributed by Hypertension. Public health midwives sometimes attend to these obsterical emergencies often in the absence of a physician. this led to the BEmONC program, which addresses the rising morbidities from far-flung areas where resources are scarce, and helps train midwives in essential obsterical emergency care. The midwives are our allies in providing the best standard of care every mother and child rightfully deserves. Only thru periodic evaluation can we help strengthen BEmONC program, making it crucial to evaluate the midwives' knowledge and management practices in hypertension to help identify the setbacks that have impeded our progress in achieving the MDG.
GENERAL OBJECTIVE: To access the knowledge and management practices of midwives in the management of hypertension in pregnancy in accourdance to the BEmONC protocol.
STUDY DESIGN: Descriptive Study
STUDY SETTING: The 69 public health centers of Cebu City
STUDY POPULATION: Public Health Midwives
METHODOLOGY:This is descriptive study where a survey questionnaire was used and convenience sampling was done. Chi square and Fischer exact tests were employed to compare proportions. Descriptive statistics was used to summarize the data in proportion.
RESULT: More than 70% of the midwives were knowledgeable regarding expected competencies, where BEmONC-trained midwives were 5-14x more likely to identity appropriate function. However, Only a dismal 22-36% will actually administer Magnesium Sulfate, which shows that knowledge is not translated into practice. Also, more than 70% were knowledgeable on the risk factors and danger signs of hypertension in pregnancy. It also showed that the midwives agreed to give antihypertensive medications- where Methyldopa was commonly given. Among those who agreed too give Methyldopa, majority were BEmONC-trained. A number also agreed to give hydralazine and diazepam in the setting of sever preeclampsia and eclampsia, where more non-BEmONC midwives agreed. Alarmlingly, only less than 50% will refer to a physician in the management og gestational hypertension and mild preeclampsia, and only 50%-60% agreed to facilitate hospital transport in the setting of severe preeclampsia and eclampsia.
CONCLUSION: The BEmONC manual must be updated to keep up with current guidelines and ensure the conversation of knowledge into practice. The BEmONCcoverage of training must also be expanded so that all practicing midwives know the protocol. However, the DOH must further strengthen their role in the active surveillance of public health midwives and review the retention of their skills and regular practice of knowledge. Midwives must also be certified proficient, not merely trained. The must also be consulted to explore their problems in the implementation of current guidelines so we can better understand their situation as to why knowledge is not put into practice. By identifying deficiencies, we can improve and address setbacks that have impeded our progress towards achieving the Millennium Development Goal.

Rhynchophylline (RP) is a major tetracyclic oxindole alkaloid of Uncariae Ramulus et Uncus which has been used to treat hypertension, seizures, pain and anxiety in the oriental countries. A recent report revealed that RP attenuated ischemia-induced neuronal damage and kainite-induced convulsions in animals. This study was performed to investigate whether RP enhances pentobarbital-induced sleep behaviors and modulates sleep architecture in mice. Locomotor activity was significantly inhibited by RP at 0.25 and 0.5 mg/kg, similar to 2 mg/kg diazepam (a benzodiazepine agonist) in mice. RP shortened sleep latency and increased total sleep time in a dose-dependent manner when administrated with pentobarbital (42 mg/kg, i.p.). RP also increased the number of sleeping mice and total sleep time by concomitant administration with the sub-hypnotic dosage of pentobarbital (28mg/kg, i.p.). On the other hand, RP (0.25mg/kg, p.o.) itself significantly inhibited sleep-wake cycles, prolonged total sleep time, and rapid eye movement in rats. In addition, RP also increased chloride influx in the primary cultured hypothalamic neuronal cells. In addition, we found that glutamic acid decarboxylase (GAD(65/67)) was activated by RP. In conclusion, RP augments pentobarbital-induced sleeping behaviors, and can be a candidate for treating insomnia.
