Abstract
INTRODUCTION We aimed to clarify the risks of initiating antidiabetic drugs for fractures using a nationwide health insurance claims database (NDBJ). MATERIALS AND METHODS Patients aged ≥ 65 years initiating antidiabetic drugs at the outpatient department were enrolled after a 180-day period without prescribed antidiabetic drugs and followed with during 2012-2018 using NDBJ. The adjusted hazard risks (HRs) of each antidiabetic drug (thiazolidine, alpha-glucosidase inhibitor, dipeptidyl peptidase-4 [DPP-4] inhibitor, sulfonylurea, glinide, and insulin) for fractures compared with biguanide were obtained adjusting for age, gender, polypharmacy, dementia, and the other antidiabetic drugs. RESULTS The DPP-4 inhibitor was the most often prescribed antidiabetic drug followed by biguanide with prescribed proportions of 71.7% and 12.9%. A total of 4,304 hip fractures and 9,388 vertebral fractures were identified among the 966,700 outpatient participants. Compared with biguanide, insulin, alpha-glucosidase inhibitor, and DPP-4 inhibitor were related to increased hip fracture risks. Vertebral fracture risk was higher in outpatients prescribed with insulin, thiazolidine, and DPP-4 inhibitor compared with biguanide. Patients prescribed insulin for hip and vertebral fractures' adjusted HRs were 2.17 (95% CI 1.77-2.66) and 1.45 (95% CI 1.24-1.70), respectively. Those prescribed DPP-4 inhibitor for hip and vertebral fractures' adjusted HRs were 1.27 (95% CI 1.15-1.40) and 1.20 (95% CI 1.12-1.28), respectively. CONCLUSIONS Initiating insulin increased the risk of not only hip fractures but also vertebral fractures. Patients initiating antidiabetic drugs had increased risks of hip and vertebral fractures compared with those initiating biguanide independently for age, gender, polypharmacy, and dementia in the Japanese elderly.

Abstract
Biguanide is an ideal drug for the treatment of type 2 diabetes mellitus. When used appropriately, the incidence of lactic acidosis is reported to be very low. Risk factors associated with biguanide-related lactic acidosis include chronic kidney disease, congestive heart failure, alcohol use, severe dehydration, shock, hypoxic states, sepsis, and advanced age. We herein report a case of cardiac dysfunction due to thiamine deficiency after hemodialysis in a patient with suspected biguanide-related lactic acidosis. Patients who develop severe lactic acidosis while taking biguanides should be given a large dose of thiamine without delay, given the possibility of thiamine deficiency as a complication.

Abstract
Background In Morocco, and many other African countries, there is a paucity of antihypertensive and antidiabetics use amongst the general population. Aim To investigate the epidemiological profile of antihypertensive and antidiabetics use and analysis their adverse reactions. Setting This study was conducted in the prefecture of Figuig, Morocco. Methods A cross-sectional descriptive study. Data was collected using semi-structured questionnaire about their pharmacological treatment and presented using descriptive statistical analysis. Results Sample of 244 subjects, predominantly women 58.15% (p < 0.03) composed of diabetic patients 56.96% (n = 139) and hypertensive patients 43.03% (n = 105). After adjustments, 60.24% of all patients were under monotherapy. The diabetics were being treated using the Biguanide class (26.92%), insulin (20.0%) and sulfonylureas (10.0%) while hypertensive patients were treated by Calcium Channel Blockers (27.36%), Angiotensin Converting Enzyme Inhibitors (21.05%), Angiotensin T-Blockers (16.84%), Diuretics (7.36%) and β-adrenergic receptors blockers (3.15%). In total, 23.00% of all subjects have experienced negative side-effects, mostly, reported (90.38%) to health professionals and 23.52% of them have interrupted temporarily or try to change their treatment. Gastro-intestinal problems were the most adverse reactions reported (11.11%) followed by headache, dizziness and tinnitus (6.66%) and asthenia, feeling sick and feeling of faintness (5.33%). Conclusion Managing diabetes and hypertension entails a lot of public challenges and requires more focus and interest, especially amongst the illiterate population in remote areas. Some of the suggested ways to help face the problem include the introduction of new innovative measures, systems of fellow-up and adverse reactions.

Abstract
CASE REPORT A 72-year-old woman with a nontraumatic spinal cord injury developed eschar on her lower right back. An underlying abscess was identified, which upon surgical debridement left a large wound extending down to the hip bone. In addition, the hip suffered from chronic osteomyelitis and was exposed at the bottom of the wound. The wound was initially treated for 5 weeks with Manuka honey but deteriorated further. Next, micropore particle technology (MPPT) was used. It cleared the wound of necrotic tissue based on autolytic debridement and removed the soft tissue infection; over a 3-month period, the wound reduced 50% in volume. Treatment approach was changed to polyhexamethylene biguanide (PHMB) and was applied as a gel once every second day to the wound. After 6 days, it was observed to cause tissue degeneration, disruption of the structure of the exposed bone, and the appearance of froth coming through the hip bone. A pain syndrome developed and the use of PHMB was terminated on day 10. After a wash-out period, the use of MPPT was reinitiated. Over the following 8 months, MPPT continued to control the infectious debris coming from the hip bone and promote healing without affecting the bone or causing side effects. CONCLUSIONS It is generally assumed that the cytotoxic properties of antiseptics seen in cell culture experiments do not occur on wounds. The present case shows these cytotoxic properties are expressed on wounds, and they do disrupt tissues and tissue regeneration.

Abstract
PURPOSE OF REVIEW There are currently over 40 different drugs in 12 distinct classes approved in the USA to treat patients with type 2 diabetes mellitus. This review summarizes our current knowledge about potential side effects of antidiabetic therapy and attempts to apply it to a clinical practice setting. RECENT FINDINGS Given the heterogeneity of both the patients and the disease, it is mathematically impossible to test every available drug combination in long-term outcome, prospective, randomized blinded fashion before a clinician decides which agent(s) to prescribe to a specific patient in a given situation. To complicate the clinician's dilemma, there is lack of available tests to predict an individual's response or propensity to side effects. Further, the data available are derived from small, short-term registration trials and typically focus on relative rather than absolute risks of any given drug and do not address the potential adverse outcomes if a patient's diabetes remains untreated. Clinicians have to personalize their choice of antidiabetic therapy based both on the specific characteristics of the patient in front of them (stage of diabetes and its complications, overall health status, socioeconomic situation, other medications present, desire to improve control of diabetes, etc.) and the current knowledge about the relative and absolute balance of benefits and risks of any individual medication in that specific patient. It has to be recognized that this requires constant re-evaluation as database of our experience with antidiabetic therapy expands.

Abstract
Biguanides are a drug of choice for the treatment of type 2 diabetes mellitus. Although they can cause lactic acidosis in susceptible patients with predisposing risk factors, the incidence of lactic acidosis is reported to be very low when they are used properly. We herein present a case of biguanide-associated severe lactic acidosis complicated with thiamine deficiency that was provoked without predisposing factors for thiamine deficiency. Diabetic patients taking biguanide may be predisposed to thiamine deficiency, even when there is no evidence of risk factors, and the high-dose administration of thiamine may be essential in the treatment of this otherwise under-recognized disorder.

Abstract
UNLABELLED The aim of our study was to determine the efficacy and tolerability of local therapy with polyhexamethylene biguanid hydrochloride (BIGUANELLE) in women with anaerobic vaginal infection. MATERIAL AND METHODS We include in our study 23 women (18-50) with established by AMSEL criteria bacterial vaginosis. In all of the women at the beginning and at the end of the survey was performed gynecological examination and microbiological research (AMSEL). The therapeutic scheme at all women is with a single vaginal application of gynecological solution BIGUANELLE. Effectiveness of the treatment was evaluated according to clinical complaints and microbiological research (Amsel criteria: Ph 4.5 >; KOH (+); "clue cells"; specific vaginal fluorine). Tolerability of patients to treatment was assessed by questionnaire. RESULTS Clinical complaints of patients after the therapy decreased as follows: vaginal fluorine with 73.9%; odor--75%; pruritus--50%; discomfort--90%. Microbiological research and their evaluation by AMSEL, showed the therapeutic efficacy of the therapy in 16 (69.6%) of all (n-23) patients. At 7 (30.4%) women, the treatment remained without effect. At questionnaire answers, 73.9% patients were satisfied with the application of BIGUANELLE, 95.6% of them have implemented it easily, 95.6% of women believe that BIGUANELLE is more convenient to use in comparison with similar products which have a daily application, and none of the patients (100%) have any complaints in applying this gynecological solution. CONCLUSIONS BIGUANELLE showed good clinical efficacy in the treatment of bacterial vaginosis. It is easily applied and well tolerated by the patients.

Abstract
The efficacy and tolerability of once weekly dulaglutide 0.75 mg in Japanese patients with type 2 diabetes (T2D) were evaluated by subgroups defined by key demographic characteristics. This post hoc analysis included data from patients who received dulaglutide 0.75 mg for up to 26 weeks in three phase 3 trials (one open-label, randomized; one double-blind and open-label, randomized; one open-label, nonrandomized). Patients were classified into subgroups on the basis of sex (male, female), age (<65, ≥65 years), body weight (<70, ≥70 kg), body mass index (BMI; <25, ≥25 kg/m(2)), duration of diabetes (<7, ≥7 years), HbA1c (≤8.5, >8.5%), use of concomitant sulfonylurea (yes, no), and use of concomitant biguanide (yes, no). Efficacy measures analyzed were changes from baseline in HbA1c and body weight and percentages of patients achieving HbA1c <7.0%. Safety measures analyzed were incidence of hypoglycemia and nausea and change from baseline in seated pulse rate. A total of 855 patients were analyzed. Once weekly dulaglutide 0.75 mg improved blood glucose control as measured by HbA1c regardless of patient characteristics; patients with higher baseline HbA1c values had greater improvements compared to patients with lower baseline values. Weight loss was greater in patients with lower baseline HbA1c and in patients taking concomitant biguanides. Concomitant use of sulfonylureas had the greatest effect on the incidence of hypoglycemia. Treatment of T2D with once weekly dulaglutide 0.75 mg for 26 weeks was associated with significant improvement in glycemic control irrespective of age, sex, duration of diabetes, body weight, BMI, or concomitant medication.

Abstract
Only four cases of anaphylaxis triggered by polyhexanide have been reported in the literature. We report a case of anaphylaxis in a Danish patient treated with polyhexanide derivate (Prontosan) wound products. We emphasise the importance of intramuscular injection of adrenaline as part of the treatment protocol in the initial phase of anaphylaxis and stress the importance of being aware of polyhexanide as a potential trigger of anaphylaxis.

Abstract
The question whether antidiabetes drugs can cause acute pancreatitis dates back to the 1970s. Recently, old concerns have re-emerged following claims that use of incretins, a new class of drugs for type 2 diabetes, might increase the relative risk of acute pancreatitis up to 30-fold. Given that diabetes is per se a potent risk factor for acute pancreatitis and that drug-related acute pancreatitis is rare and difficult to diagnose, we searched the medical databases for information linking acute pancreatitis and type 2 diabetes drugs. Among the biguanides, both phenformin and metformin (the latter in patients with renal insufficiency) have been cited in case reports as a potential cause of acute pancreatitis. Sulphonylureas, as both entire class and single compound (glibenclamide), have also been found in cohort studies to increase its risk. No direct link was found between pancreatic damage and therapy with metaglinide, acarbose, pramlintide or SGLT-2 inhibitors. In animal models, thiazolinediones have demonstrated proprieties to attenuate pancreatic damage, opening perspectives for their use in treating acute pancreatitis in humans. Several case reports and the US Food and Drug Administration pharmacovigilance database indicate an association between acute pancreatitis and incretins, dipeptidyl peptidase-4 (DPP-4) inhibitors, and GLP-1 receptor agonists. To date, however, a clear-cut odds ratio for this association has been reported in only one of eight pharmacoepidemiological studies. Finally, none of the intervention trials investigating these compounds, including two large randomized controlled trials with cardiovascular endpoints, confirmed the purportedly increased risk of acute pancreatitis with incretin use.

Abstract
OBJECTIVES To determine whether Asian and white subjects differ in clinical signs or subjective symptoms in response to the use of different biguanide-preserved contact lens care solutions. METHODS Forty-two subjects (15 Asian and 27 white) wearing lotrafilcon B silicone hydrogel contact lenses used a preservative-free lens care solution bilaterally for 2 weeks, then used two biguanide-preserved solutions (solution 1: ReNu MPS; solution 2: AQuify MPS) contralaterally in randomly assigned eyes for 4 weeks. Comprehensive ocular surface examinations were performed and symptomatology questionnaires were administered every 2 weeks. Investigators were masked as to solution assignment during examinations, whereas subjects were not to avoid potential difficulties in compliance with the protocol. RESULTS With solution 1, most Asian and white subjects had grade 2 or greater corneal staining after 2 weeks (67% and 59%, respectively) and 4 weeks (60% and 67%, respectively). With solution 2, grade 2 or greater corneal staining occurred in 40% of Asians after 2 weeks and in 13% after 4 weeks, but in only 4% of whites after 2 weeks and 0% after 4 weeks. Whites reported significantly better average comfort (P=0.046) and less dryness (P<0.001) than did Asians. CONCLUSIONS Asians and whites differ in both ocular response to the use of contact lens care solutions and in reporting subjective symptoms. Racial and ethnic differences should be considered when evaluating and treating contact lens patients in a clinical setting.

Abstract
AIMS To analyse the association between cancer incidence and oral diabetes therapy (biguanide, sulphonylurea, thiazolidinedione and meglitinide) in men and women with type 2 diabetes mellitus. METHODS A retrospective analysis of the electronic health record-based Cleveland Clinic Diabetes Registry (25 613 patients) was cross-indexed with the histology-based tumour registry (48 051 cancer occurrences) over an 8-year period (1998-2006). Multiple imputations were used to account for missing data. Cox regression with propensity scores was used to model time for the development of incident cancer in each of the imputed datasets and the results were pooled. RESULTS During 51 994 person follow-up years, 892 incident cancer cases were identified; prostate (14.5%) and breast (11.7%) malignancies were most frequent. In women, thiazolidinedione use was associated with a 32% decreased cancer risk compared with sulphonylurea use [hazard ratio (HR) 0.68; 95% confidence interval (CI) 0.48-0.97, in the adjusted analysis]. Comparison of insulin secretagogues (sulphonylurea and meglitinide) versus insulin sensitizers (biguanide and thiazolidinedione) demonstrated a 21% decreased cancer risk in insulin sensitizers [HR 0.79 (95% CI 0.64-0.98) in the adjusted analysis]. Oral diabetes therapy showed no significant difference in men. Adjustments were made for age, body mass index (BMI), low-density lipoprotein (LDL), high-density lipoprotein (HDL), triglycerides, coronary heart disease (CHD), diabetes oral monotherapy, race, gender, haemoglobin A1c, statin use, income, insulin use, glomerular filtration rate (GFR), new diabetes status, prior cancer, prior cerebrovascular accident (stroke or transient ischaemic event), systolic/diastolic blood pressure, tobacco use (ever/never) and the propensity score for receiving a biguanide. CONCLUSIONS Oral insulin sensitizers, particularly thiazolidinedione, are associated with decreased malignancy risk in women with type 2 diabetes mellitus.

Abstract
Current strategies for the treatment of type 2 diabetes mellitus promote individualized plans to achieve target glucose levels on a patient-by-patient basis while minimizing treatment related risks. Maintaining glycemic control over time is a significant challenge because of the progressive nature of diabetes as a result of declining β-cell function. This article identifies complications of non-insulin treatments for diabetes. The major classes of medications are reviewed with special focus on target population, mechanism of action, effect on weight, cardiovascular outcomes and additional class-specific side effects including effects on bone. Effects on β-cell function are also highlighted.

Abstract
Dipeptidyl peptidase-4 (DPP-4) inhibitors are a newer class of oral hypoglycemic agents for the management of diabetes that elevate the plasma concentration of active glucagon-like peptide-1 via inhibition of DPP-4. They effectively lower not only glycosylated hemoglobin levels, but also fasting and postprandial plasma glucose levels. Patients with diabetes occasionally consume an overdose of oral hypoglycemic agents in suicide attempts: the prevalence of depression is high in patients with diabetes, and depression is a strong risk factor for suicide. We encountered an 86-year-old woman with type 2 diabetes and depression, who was transferred to the emergency room 4h after ingestion of 1,700 mg of the DPP-4 inhibitor sitagliptin (1,700 mg is 17 times greater than the approved maximum dose). Upon arrival, she was fully conscious, plasma glucose was 124 mg/dL, and serum immunoreactive insulin level was 5.81 µU/mL. Thereafter, the plasma concentration of sitagliptin rose to 3,793 nM, which is 4.5 times higher than the value found under regular treatment with the maximum dose. The patient did not suffer from hypoglycemia, suggesting that a single oral overdose of sitagliptin is unlikely to cause hypoglycemia. A literature review of oral anti-diabetic agents revealed that overdose of biguanides is occasionally fatal when immediate intensive care is not provided. In summary, sitagliptin is a good treatment option for diabetic elderly patients or patients with psychiatric disorders who are suicidal and do not require insulin.

Abstract
Polihexanide-containing wound products are often used for the treatment of acute and chronic wounds. Although information pertaining to the use of polihexanide can be found in the literature, the appropriate use of these products in clinical practice is not always clear. The goal of this short review is to provide clinically relevant recommendations to physicians and nurses treating patients with acute and chronic wounds. This review describes the clinically relevant characteristics of polihexanide and gives recommendations for the prophylaxis and treatment of wound infections.

Abstract
PURPOSE To describe the current management of Acanthamoeba keratitis (AK). DESIGN A perspective based on the literature and author experience. RESULTS Early diagnosis and appropriate therapy are key to a good prognosis. A provisional diagnosis of AK can be made using the clinical features and confocal microscopy, although a definitive diagnosis requires culture, histology, or identification of Acanthamoeba deoxyribonucleic acid by polymerase chain reaction. Routine use of tissue diagnosis is recommended, particularly for patients unresponsive to treatment for AK. Topical biguanides are the only effective therapy for the resistant encysted form of the organism in vitro, if not always in vivo. None of the other drugs that have been used meet the requirements of consistent cysticidal activity and may have no therapeutic role. The use of topical steroids is controversial, but probably beneficial, for the management of severe corneal inflammatory complications that have not responded to topical biguanides alone. The scleritis associated with AK is rarely associated with extracorneal invasion and usually responds to systemic anti-inflammatory treatment combined with topical biguanides. Therapeutic keratoplasty retains a role for therapy of some severe complications of AK but not for initial treatment. With modern management, 90% of patients can expect to retain visual acuity of 6/12 or better and fewer than 2% become blind, although treatment may take 6 months or more. CONCLUSIONS Better understanding of the pathogenesis of the extracorneal complications, the availability of polymerase chain reaction for tissue diagnosis, and effective licensed topical anti-amoebics would substantially benefit patients with AK.

Sitagliptin + metformin: new combination. Do not use this combination. Sitagliptin provides a slight increase of glucose-lowering effects, but there is a disturbing potential for long-term adverse effects: infections, depression, and cancer.

Abstract
For a continuous monitoring and evaluation of drug safety problems in Sweden, the Department of Drugs of the National Board of Health and Welfare has access to a number of computerised patient-, drug-, and disease-oriented registers. The usefulness and limitations of these registers are presented by examples. A recent increase in asthma deaths is presently being analysed by comparing information from death certificates and case records with drug sales and prescription data. A recent analysis of the cancer register showed no increased risk of malignant thyroid tumors after diagnostic or therapeutic doses of I 131. Similarly no increased risk of malformations after occupational exposure to hexachlorophene could be detected by analysing the malformation and medical birth-record registers in relation to hospital hexachlorophene use. The register of patient discharge diagnoses has been repeatedly used to analyse the incidence and pattern of drug induced blood dyscrasias and thromboembolism associated with oral contraceptives (OC). These analyses have resulted i.a. in the withdrawal of dipyrone and tenalidine and a decrease of the estrogen-content of OCs. At the same time about 1/3 of these serious adverse drug reactions (ADR) was found to have been reported to the ADR-register. By combining sales and prescription data with ADR-reports the risk of inducing lactic acidosis was found to be significantly higher for phenformin than for metformin. Also the incidence of tardive dyskinesia from longterm use of metoclopramide was found to be much higher than hitherto recognized. By use of these registers it is possible to obtain valuable information about the safety of drugs. The raw data must, however, be interpreted with care and often be supplemented with in depth studies of the various problems.

Abstract
PURPOSE Data on cardiovascular outcomes among treated diabetics have been inconsistent. Our goal was to compare cardiovascular outcomes associated with different treatments for diabetes. METHODS This is a retrospective cohort study of diabetic patients at least 40 years of age treated in general practices participating in The Health Information Network (THIN) data system between 2002 and 2006. Our primary outcome was serious atherosclerotic vascular disease of the heart. RESULTS Among all diabetics (N = 63 579), the fully adjusted hazard ratios of association with our outcome were 1.2 (1.1, 1.3) for insulin, 1.03 (0.97, 1.09) for sulfonylureas, 0.8 (0.7, 0.8) for biguanide, 1.2 (0.99, 1.5) for meglitinide, 0.5 (0.5, 0.6) for thiazolidinediones, and individually 0.6 (0.5, 0.6) for rosiglitazone, and 0.5 (0.4, 0.7) for pioglitazone. Among those individuals newly diagnosed and treated for diabetes after 2002 (N = 13 576), the adjusted hazard ratios of association with our outcome were 2.4 (2.0, 2.9) for insulin, 1.4 (1.2, 1.7) for sulfonylureas, 0.5 (0.4, 0.5) for biguanide, 0.9 (0.4, 2.1) for meglitinide, 0.8 (0.7, 1.0) for thiazolidinediones, and individually 0.8 (0.6, 1.0) for rosiglitazone, and 0.9 (0.6, 1.4) for pioglitazone. Risk increased as total duration of therapy increased for insulin, sulfonylureas, and biguanide, but decreased with duration for rosiglitazone and pioglitazone. CONCLUSIONS Overall, insulin was associated with an increased risk of myocardial infarction. Its risk increased with longer use, and risk emerged with longer use of sulfonylureas and biguanide. Conversely, a protective effect emerged with longer use of rosiglitazone or pioglitazone.

Abstract
The use of oral anti-diabetes medicines should be considered when nutritional control methods and physical exercise programs have failed. These medicines have several types of active mechanisms: to stimulate pancreatic secretion of insulin, to delay the absorption of carbohydrates in the intestines, to sensitize tissues to the action of insulin. Sulfonylureas are the pharmaceutical group most commonly utilized in the treatment of type 2 diabetes mellitus.

Abstract
OBJECTIVE At the present the clinical treatment of choice of bacterial vaginosis (BV) is the use of systemic or local metronidazole or clindamycin. Aim of the study was to evaluate the efficacy and tolerability of a single dose of gynaecologic solution, Polyhexamethylene Biguanide (PHMB), Monogin, in the treatment of BV in comparison to a 7-days treatment with clindamycin vaginal cream. STUDY DESIGN This multicenter, randomized, single-blind, parallel-group study enrolled 740 patients with BV infections. Treatment consisted of either a single intravaginal dose of PHMB or 7 daily doses of Clindamycin. Efficacy and safety were assessed 21-30 days after the start of treatment. The efficacy endpoints were Investigator Cure, Clinical Cure (a composite of all 4 Amsel's criteria and investigator Cure), Nugent Cure (Nugent score < 4), and therapeutic cure (a composite of clinical cure and Nugent Cure). Resolution of individual Amsel's criteria was also evaluated. Any adverse event of the treatment has been monitored throughout the study. RESULTS No significant differences has been reported in cure rates between the PHMB and Clindamycin treatment groups in Investigator Cure (P = 0.702), Clinical Cure (P = 0.945), Nugent Cure (P = 0.788), or Therapeutic Cure (P = 0.572). Results were also similar for 3 of 4 and 2 of 4 Amsel's criteria and for each individual Amsel's criterion (all P-values > 0.200). Ninety-five percent confidence intervals for each endpoint were consistent with equivalence between the 2 products. There was no significant difference between the treatment groups in the incidence of treatment-emergent adverse events (P = 0.386). CONCLUSIONS A single dose, of PHMB gynaecologic solution (Monogin) is equivalent in safety and efficacy to a 7-dose regimen of Clindamycin vaginal cream in the treatment of bacterial vaginosis. Futhermore the compliance as been reported to be higher for the single-dose treatment with PHMB than with 7-days treatment with Clindamycin.
