Objective: This study aims to determine the association of serum magnesium with distal symmetric peripheral neuropathy among persons with type 2 diabetes mellitus (DM). Methodology: A cross-sectional analytical study among adult Filipinos with Type 2 DM. Logistic regression was used to determine the association of serum magnesium with DSPN diagnosed by the Michigan Neuropathy Screening Instrument. The null hypothesis was rejected at 0.05α-level of significance. Results: The average serum magnesium levels were similar between those with versus without DSPN (2.06 ± 0.32 vs 2.05 ± 0.23, p = 0.873); the same was seen for corrected magnesium. There is insufficient evidence to demonstrate a significant statistical difference between those with and without DSPN in relation to glycemic control (HbA1c and FBS). Likewise, there is no significant statistical correlation between serum magnesium levels with HbA1c, FBS, BMI, or duration of diabetes. Conclusion This present study could not demonstrate any association between DSPN and serum magnesium, even after adjusting for age, sex, and comorbidity.

OBJECTIVE: This study was designed to compare the efficacy and safety of the ritodrine hydrochloride alone with combined treatment with magnesium sulfate in the management of preterm labor. METHODS: One hundred thirty three singleton pregnancies with preterm labor were treated with either ritodrine hydrochloride (n=97) or ritodrine hydrochloride and magnesium sulfate (n=36). The principal outcomes assessed were delay of duration, maternal-fetal side effects, and fetal outcome. RESULTS: The treatment to delivery time was not statistically different between the ritodrine group and the combined magnesium sulfate group (mean+/-SD 10.7+/-13.0 days, 8.6+/-9.1 days, respectively). The proportion delivered after 48 hours, 72 hours, or 7 days was also not statistically different between two groups (29% vs. 22%, 40% vs. 39%, 60% vs. 64%, respectively). No statistical difference was found in the side effects of treatment or fetal outcomes. CONCLUSION: There was no significant difference in efficacy and safety between ritodrine hydrochloride and combined treatment with magnesium sulfate in the management of preterm labor.

Primary hypomagnesemia is a rare inherited disorder and it is considered to be due to either a defect in the intestinal transport of magnesium or a defect in renal tubular transport. It is important to measure the urinary excretion of magnesium to differentiate the causes of magnesium deficiency. We report here an one-month-old female infant of primary hypomagnesemia who presented generalized tonic-clonic seizures. She had hypomagnesemia(<1.5mg/dL) and several seizure attacks but normal magnesium creatinine ratio in random urine and normal magnesium excretion in 24-hour urine. Continuous oral magnesium supplementation was necessary to avoid the recurrence of symptoms and maintain serum rnagnesium levels.

BACKGROUND: Perioperative magnesium sulfate (MgSO4) is used for analgesic, anti-arrhythmic, and obstetric purposes. The effects of MgSO4 on the neuromuscular blockade (NMB) induced by rocuronium, and the sugammadex reversal thereof, have not been clearly quantified. We investigated the effect of various MgSO4 concentrations on the NMB by rocuronium, and sugammadex reversal, in isolated left phrenic nerve hemi-diaphragm (PNHD) preparations from the rat. METHODS: Rat PNHD preparations were randomly allocated to one of four groups varying in terms of MgSO4 concentration (1, 2, 3, and 4 mM, each n = 10, in Krebs solution). The train-of-four (TOF) and twitch height responses were recorded mechanomyographically. The preparations were treated with incrementally increasing doses of rocuronium and each group’s effective concentration (EC)50, EC90, and EC95 of rocuronium were calculated via nonlinear regression. Then, sugammadex was administered in doses equimolar to rocuronium. The recovery index, time to T1 height > 95% of control, and the time to a TOF ratio > 0.9 after sugammadex administration were measured. RESULTS: The EC50, EC90, and EC95 of rocuronium fell significantly as the magnesium level increased. The EC50, EC90, and EC95 of rocuronium did not differ between the 3 and 4 mM groups. The recovery index, time to T1 height > 95% of control, and time to a TOF ratio > 0.9 after sugammadex administration did not differ among the four groups. CONCLUSIONS: Increases in the magnesium concentration in rat PNHD preparations proportionally enhanced the NMB induced by rocuronium but did not affect reversal by equimolar amounts of sugammadex.

OBJECTIVE: This study aimed to estimate the association between total and ionized magnesium, and the changes in serum magnesium and calcium levels in patients with preterm labor during magnesium sulfate (MgSO4) administration. METHODS: The study population included 64 women who were candidates for intravenous MgSO4 treatment for preterm labor. Serial blood samples were taken and measured total magnesium (T-Mg), ionized magnesium (I-Mg), total calcium (T-Ca), and ionized calcium (I-Ca) levels every one-week interval (1st, 2nd, 3rd). RESULTS: There was no significant difference in T-Mg and I-Mg levels during MgSO4 administration (P>0.05). There was no significant difference in T-Ca and I-Ca levels during MgSO4 administration (P>0.05). Compared before and after administration of MgSO4, T-Mg and I-Mg levels and T-Ca levels were changed allow statistically significant (P < 0.05). But, there was no significant difference in the I-Ca serum levels before and after MgSO4 administration (P=0.495). The I-Mg levels for patients with adverse effect were higher than other group but did not reach statistical significance (P>0.05). There was significant correlation between levels of I-Mg and T-Mg (I-Mg=0.395×T-Mg+0.144, P < 0.01). CONCLUSION: There were no significant differences in serum Mg and Ca levels during MgSO4 administration for preterm labor. Compared to the before and after administration of MgSO4, only I-Ca levels were not substantially changed. There are significant correlations between I-Mg and T-Mg levels during administration of MgSO4 and I-Mg level seemed to have more correlation with adverse effect than T-Mg.
