Diabetic muscular infarct: an unusual cause of extremity pain and dysfunction

Diabetic muscular infarct (DMI) is a rare condition, which begins with acute onset of extremity pain and swelling. Patients usually have long-standing disease and poorly controlled diabetes mellitus (DM). Thigh muscle group is the most commonly involved side, while lower leg involvement is rare. We represent herein a 22-year-old patient with type I DM who admitted to our outpatient clinic due to painful swelling of the left leg. In physical examination, anterior left leg was painful and firm on palpation; there was diffuse swelling extending to the knee and ankle with mild local fever and redness. T2-weighted MRI demonstrated hyperintensity in left leg muscles. A biopsy confirmed the diagnosis of DMI. She was treated with glucose regulation, analgesics, antiplatelet treatment and rest. At her 6 months, recurrence of DMI was observed. DMI should be considered in diabetic patients with extremity pain and swelling. Treatment plan should include the regulation of the blood glucose and evaluation of end-organ complications, analgesia, and bed rest.     

Exotic and indigenous problem plants species used,by the Bapedi,to treat sexually transmitted infections in Limpopo Province,South Africa

Background

The ethnic usage of exotics and indigenous problem plants is a highly debated topic, as legislative requirements over-shadow their potential medicinal value, particularly to treat sexually transmitted infections (STIs). Limited information exists regarding their medicinal value among the Bapedi.

Objectives

To ascertain the importance of exotics and indigenous problem plants in the treatment of STIs, a major global primary health care challenge.

Methods

A field observation and semi-structured questionnaire focussing on species diversity, types of STIs treated and medicinal preparation as well as application was used to collect data from 34 traditional healers.

Results

Seven exotics and three indigenous problem species were identified. These species were used to treat four STIs; with Catharanthus roseus illustrating its dominance in the treatment of gonorrhoea. Some medicinal species used by Bapedi traditional healers have been validated through scientific research or through their extensive use by various cultures in South Africa and other parts of Africa. To the best of our knowledge Alternanthera pungens, Caesalpinia decapetala, Cinnamomum verum, and Citrullus lanatus are reported for the first time in the treatment of the investigated STIs.

Conclusions

Exotic and indigenous problem species constitute an important component of the STIs treatment protocol. Their utilization by Bapedi cautions against the narrow-minded approach of indiscriminate eradication, as these species can play a significant role in the primary health care needs of socio-economic vulnerable people.     

Complement associated pathogenic mechanisms in myasthenia gravis

The complement system is profoundly involved in the pathogenesis of acetylcholine receptor (AChR) antibody (Ab) related myasthenia gravis (MG) and its animal model experimental autoimmune myasthenia gravis (EAMG). The most characteristic finding of muscle pathology in both MG and EAMG is the abundance of IgG and complement deposits at the nerve–muscle junction (NMJ), suggesting that AChR-Ab induces muscle weakness by complement pathway activation and consequent membrane attack complex (MAC) formation. This assumption has been supported with EAMG resistance of complement factor C3 knockout (KO), C4 KO and C5 deficient mice and amelioration of EAMG symptoms following treatment with complement inhibitors such as cobra venom factor, soluble complement receptor 1, anti-C1q, anti-C5 and anti-C6 Abs. Moreover, the complement inhibitor decay accelerating factor (DAF) KO mice exhibit increased susceptibility to EAMG. These findings have brought forward improvisation of novel therapy methods based on inhibition of classical and common complement pathways in MG treatment.     

Management of open apices in thirteen traumatized permanent incisors using mineral trioxide aggregate: Case series

AimThe partial pulpotomy can offer a successful outcome for the treatment of traumatic complicated crown fractures. The aim of this clinical report was to evaluate the effect of mineral trioxide aggregate (MTA) in apexogenesis of traumatized immature permanent incisors with pulp exposure.Case reportAccording to clinical and radiological examinations complicated crown fractures and open apices were identified in 13 permanent upper incisors in ten patients (age range 7–10 years). Partial pulpotomy procedures were performed and the teeth were treated with MTA. In this report, periodic clinical and radiological follow-ups were performed. At recall examinations, all teeth were asymptomatic, and clinical and radiological investigations revealed excellent healing patterns with continued apexogenesis.ConclusionRegular examination of immature traumatized permanent teeth is critical for vitality and apexification. In this report, clinical and radiological findings confirm that partial pulpotomy with MTA is a reliable and effective treatment approach in apexogenesis of traumatized immature permanent incisors with pulp exposure.     

Use of home sphygmomanometers in Turkey: a nation-wide survey

The purposes of this study were to detect the prevalence of ownership of a home sphygmomanometer among hypertensive subjects through a nation-wide survey, to investigate parameters affecting ownership of a sphygmomanometer, to compare how home blood pressure monitoring (HBPM) was actually used in daily practice with some aspects of the current guidelines, and to discuss what we implemented to increase the reliability of HBPM in a developing country. A total of 2747 hypertensive patients from 34 cities, representative of the Turkish population, were enrolled in the study. A multiple-choice questionnaire was administered to each participant using the computer-assisted telephone interviewing method. Among 2747 hypertensive patients, 1281 of them (46.6%) had a home sphygmomanometer. Most of the patients were using wrist devices. The factors associated with ownership of a sphygmomanometer were female gender, older age, obesity, higher educational status, higher income level, living in urban areas, awareness of hypertension and anti-hypertensive drug usage. Only 16% of the devices were used on the advice of a physician. The patients learned usage of their device mainly from the sellers and their relatives. The ownership of a home sphygmomanometer is common among hypertensive patients in Turkey, but regular monitoring of blood pressure before physician visits is rare despite common ownership of these devices. Daily practice of HBPM in Turkey was far from the recommendations of the current guidelines. More effort is needed to improve the reliability of HBPM.     

Atrial conduction time and atrial mechanical function in patients with impaired fasting glucose

Background

Prolonging atrial conduction time, as measured by tissue Doppler imaging (TDI), is an independent predictor of new onset or recurrent atrial fibrillation (AF). We investigated atrial conduction time and cardiac mechanical function in patients with impaired fasting glucose (IFG) using echocardiography.

Methods

Thirty patients with IFG (19 males and 11 females; age, 46.9?±?9.5?years) and 30 control subjects (18 males and 12 females; age, 46.7?±?8.2?years) were included. Atrial conduction time was determined from the lateral mitral annulus (PA lateral), septal mitral annulus (PA septal), and lateral tricuspid annulus (PA tricuspid) by TDI. Inter- and intra-atrial electromechanical delays (EMDs) were calculated. Left atrial (LA) volumes were determined according to the biplane area?Clength method. LA mechanical function parameters were calculated.

Results

LA passive emptying volume and LA passive emptying fraction decreased significantly in patients with IFG as compared with control subjects (p?<?0.001 and p?<?0.001, respectively). PA lateral and PA septal durations were significantly higher in patients with IFG than in the control group. However, no difference in PA tricuspid duration was observed between the two groups. Inter- and intra-atrial EMDs were significantly higher in patients with IFG as compared with the control subjects (median [interquartile range], 34.0 [17.0] vs. 17.0 [4.0], p?<?0.001 and 15.0 [8.5] vs. 7.5 [2.0], p?<?0.001, respectively). Positive correlations were detected between both inter- and intra-atrial EMD and glucose levels (r?=?0.76, p?<?0.001 and r?=?0.68, p?<?0.001, respectively). Additionally, a multiple linear regression analysis revealed that glucose levels were independently associated with inter-atrial EMD (???=?0.753, p?<?0.001).

Conclusion

We showed that IFG was associated with inter- and intra-atrial EMD. Our findings suggest that IFG is an etiological factor for the development of AF.     

Can dynamic and static pupillary responses be used as an indicator of autonomic dysfunction in patients with obstructive sleep apnea syndrome?

Purpose

We aimed to reveal whether static and dynamic pupillary responses can be used for the detection of autonomic nervous system (ANS) dysfunction in patients with obstructive sleep apnea syndrome (OSAS).

Methods

We included in this study patients with OSAS, who were divided into three groups according to the apnea–hypopnea index (AHI) (group 1, mild [n?=?20]; group 2, moderate [n?=?20]; and group 3, severe [n?=?20]), and healthy controls (group 4, n?=?20). Pupillary responses were measured using a pupillometry system.

Results

Static (mesopic PD, P?=?0.0019; low photopic PD, P?=?0.001) and dynamic pupil responses (resting diameter, P?=?0.004; amplitude of pupil contraction, P?<?0.001; duration of pupil contraction, P?=?0.022; velocity of pupil contraction, P?=?0.001; and velocity of pupil dilation, P?=?0.012) were affected in patients with different OSAS severities. Also, AHI was negatively correlated with mesopic PD (P?=?0.008), low photopic PD (P?=?0.003), resting diameter (P?=?0.001), amplitude of pupil contraction (P?<?0.001), duration of pupil contraction (P?=?0.011), velocity of pupil contraction (P?<?0.001), and velocity of pupil dilation (P?=?0.001).

Conclusion

We detected pupil responses innervated by the ANS were affected in the OSAS patients. This effect was more significant in the severe OSAS patients. Therefore, the pupillometry system can be an easily applicable, noninvasive method to detect ANS dysfunction in the OSA patients.
