Restoration of horizontal stability in complete acromioclavicular joint separations: surgical technique and preliminary results

Background

Our purpose was to investigate the clinical efficacy of arthroscope-assisted acromioclavicular ligament reconstruction in combination with double endobutton coracoclavicular ligament reconstruction for the treatment of complete acromioclavicular joint dislocation.

Methods

During the period from February 2010 to October 2012, ten patients with Rockwood types IV and V acromioclavicular joint dislocation were hospitalized and nine were treated with acromioclavicular ligament reconstruction combined with double endobutton of coracoclavicular ligament reconstruction. The improvement in shoulder functions was assessed using a Constant score and visual analog scale (VAS) system.

Results

The mean follow-up period was 33.6 ± 5.4 months. The mean Constant scores improved from 25.2 ± 6.6 preoperatively to 92.4 ± 6.5 postoperatively, while the mean VAS score decreased from 5.9 ± 1.4 to 1.2 ± 0.9; significant differences were observed. The final follow-up revealed that excellent outcomes were achieved in eight patients and good outcome in two patients.

Conclusion

Arthroscope-assisted acromioclavicular ligament reconstruction in combination with double endobutton of coracoclavicular ligament reconstruction is an effective approach for treatment of acute complete acromioclavicular joint dislocation.     

Adrenaline,Noradrenaline and Dopamine Level Estimation in Depression : Does it Help?

Background

Abnormalities of catecholaminergic function have been hypothesised in causation of depressive illness. Electroconvulsive therapy (ECT) is postulated to have noradrenergic mechanism of action. We studied the clinical utility of estimating catecholamines level changes after ECT.

Methods

Plasma adrenaline, noradrenaline and dopamine in healthy controls and depressed patients were estimated by high performance liquid chromatography with electrochemical detection method before and after ECT.

Result

Mean ± standard deviation of plasma adrenaline, noradrenaline and dopamine in controls was 36.7 ± 13.2, 209.3 ± 76, 21.8 ± 9.5 ng/L respectively, while in depressed patients before and after ECT it was found to be 32.5 ± 12.0, 419.3 ± 167.7, 22.1 ± 16.0ng/ L and 37.2 ± 19.6, 386.1 ± 168.4, 22.3 ± 15.5ng/L respectively. Correlation of adrenaline, noradrenaline and dopamine concentration with scores of Beck Depression Inventory, Suicidal Ideation Scale and Melancholia Inventory was positive but statistically not significant and poor. Based on the cut off values of noradrenaline, only 62% cases could be categorized as abnormal, which after ECT reduced to 50%, whereas post ECT psychiatric ratings was normal in about 78% cases.

Conclusion

There is no clinical significance of estimating adrenaline, noradrenaline and dopamine in depressed patients.Key Words: Electroconvulsive therapy, Adrenaline, Noradrenaline, Dopamine, Psychiatric scales     

Left ventricle diastolic function in the patients after coronary arteries bypass graft combined with left ventricle aneurismectomy according to tissue doppler imaging: one year follow-up

Aim

To evaluate left ventricle (LV) diastolic function dynamics in patients after acute myocardial infarction (AMI) after combined operation of coronary artery bypass graft with LV aneurismectomy (CABG + AE) according to the results of tissue Doppler imaging (TDI).

Methods

Forty patients after AMI underwent Doppler echocardiography (EchoCG) with TDI and M‐mode colour‐flow imaging before and in 3 and 12 months after CABG + AE. Mitral annulus (MA) TDI with velocity indices was performed in 4 segments of LV.

Results

Conventional transmitral diastolic Doppler indices before and after CABG + AE remained unchanged. TDI showed significant improvement of LV systolic (systolic movement velocity S: 6.1±0.8, 7.4±1.2 and 6.9±1.3 cm/sec. before and in 3 and 12 months after the operation, respectively, p<0.01) and diastolic function after the operation (MA early diastolic movement velocity ( e''): 7.3 ± 2.1, 8.4 ± 1.5 and 8.9 ± 1.8 cm/s.; ratio of transmitral early‐flow velocity (E) to MA early‐diastolic movement velocity (E/e''): 18.4 ± 2.2, 12.3 ± 1.8 and 11.5 ± 2.3; ratio of E diastolic flow propagation velocity (Vp) 3.1 ± 0.45, 2.2 ± 0.38 and 1.8 ± 0.16 before and in 3 and 12 months after the operation, respectively, p<0.01).

Conclusions

Results of the study demonstrate significant improvement of LV diastolic function in the patient after CABG + AE according to TDI, regardless of transmitral flow pattern. TDI is more sensitive and preload independent method of LV myocardial function evaluation.     

Changes with time in skin temperature of the shoulders in healthy controls and a patient with shoulder-hand syndrome

Background

Abnormal skin temperature in the shoulder is caused by various diseases. A thermography is unable to capture temperature changes over time. In contrast, a Thermocron is an effective measuring device to monitor temperature changes over time.

Purposes

The purposes of this study employing a Thermocron were to measure shoulder skin temperature over time in healthy subjects and to detect shoulder skin temperature abnormalities in a patient with shoulder-hand syndrome.

Subjects and methods

Subjects comprised 10 healthy volunteers (20 shoulders; 4 men and 6 women, mean age 54 years). For measurements, a Thermocron was attached on both shoulders. Measurements were made from 21.00 to 07.00 the following morning at 15-minute intervals.

Results

Gradual difference in right and left shoulder skin temperature was observed with the timing of measurements but no significant difference was apparent, i.e. dominant side 34.9 ± 0.8°C, non-dominant side 34.9 ± 0.9°C (P = 0.28).

Presentation of a case with shoulder-hand syndrome

A 54-year-old woman with the diagnosis of rotator cuff tear underwent surgical treatment of rotator cuff repair, but the pain of the operated shoulder persisted due to phase 1 shoulder-hand syndrome. In postoperative week 3, skin temperature measurement using Thermocrons demonstrated a significant decrease in temperature on the operated side (affected side 34.3 ± 0.4°C, healthy side 35.2 ± 0.3°C; P < 0.05).

Conclusion

The changing of the skin temperature during night-time was successfully recorded both in the healthy subjects and a case with shoulder-hand syndrome using a Thermocron.     

The effect of polymorphism in gene of insulin-like growth factor-I on the serum periparturient concentration in Holstein dairy cows

Objective

To investigate the relationship between polymorphism within the 5′-untranslated region (5′-UTR) of IGF-I gene and its periparturient concentration in Iranian Holstein dairy cows.

Methods

Blood samples (5 mL, n = 37) were collected by caudal venipuncture from each animal into sample tubes containing the EDTA and DNA was extracted from blood. In order to measure IGF-I concentration the collection of blood samples (n = 111) was also done at 14 d before calving (prepartum), 25 and 45 d postpartum.

Results

We found evidence for a significant effect of C to T mutation in position 512 of IGF-I gene on its serum concentration in dairy cows in Iran. Cows with CC genotype had significantly higher concentration (Mean±SD) of IGF-I at 14 d prepartum (91.8±18.1) µg/L compared to those with TT genotype (73.3±14.4) µg/L (P=0.04). A significant trend (quadratic) was found for IGF-I concentration, as higher in CC cows compared to ones with TT genotype, during the 14 d before calving to 45 d postpartum (P=0.01).

Conclusions

We concluded that C/T transition in the promoter region of IGF-I gene can influence the serum concentration of IGF-I in periparturient dairy cows.     

Repetitive Transcranial Magnetic Stimulation for the Treatment of Restless Legs Syndrome

Background:

Repetitive transcranial magnetic stimulation (rTMS) is a noninvasive technique used to alter cortex excitability that has been proposed as an efficient method for treating brain hyperexcitability or hypoexcitability disorders. The aim of this study was to investigate whether high-frequency rTMS could have any beneficial effects in restless legs syndrome (RLS).

Methods:

Fourteen patients with RLS were given high-frequency rTMS (15 Hz, 100% motor threshold) to the leg representation motor cortex area of the frontal lobe for 14 sessions over 18 days. Patients were diagnosed according to the international criteria proposed by the International Restless Legs Syndrome Study Group in 2003. The International RLS Rating Scale (IRLS-RS), Pittsburgh Sleep Quality Index (PSQI), Hamilton Anxiety Scale (HAMA) and Hamilton Depression Scale were used to evaluate the severity of RLS, sleep quality, anxiety and depression, respectively. The scale scores were evaluated at four-time points (baseline, end of the 14^th session, and at 1- and 2-month posttreatment). One-way analysis of variance was used to compare scale scores at different time points.

Results:

There was significant improvement in the IRLS-RS (from 23.86 ± 5.88 to 11.21 ± 7.23, P < 0.05), PSQI (from 15.00 ± 4.88 to 9.29 ± 3.91, P < 0.05), and HAMA (from 17.93 ± 7.11 to 10.36 ± 7.13, P < 0.05) scale scores at the end of 14^th session, with ongoing effects lasting for at least 2 months.

Conclusions:

High-frequency rTMS can markedly alleviate the motor system symptoms, sleep disturbances, and anxiety in RLS patients. These results suggest that rTMS might be an option for treating RLS.     

Effects of bisoprolol and cilazapril on the central retinal artery blood flow in patients with essential hypertension—preliminary results

Background

A growing body of evidence suggests that effective blood pressure reduction may inhibit the progression of microvascular damage in patients with essential arterial hypertension. However, the potential influence of anti-hypertensive drugs on ocular circulation has not been studied sufficiently.

Purpose

The aim of our study was to evaluate the effects of anti-hypertensive therapy on blood flow in the central retinal artery in patients with systemic arterial hypertension.

Material and methods

Twenty patients with essential arterial hypertension, aged 32–46 years, were examined with Doppler ultrasonography (10 MHz ultrasound probe). Blood flow velocities, pulsatility, and vascular resistance were determined before and 3 hours after systemic application of either bisoprolol 5 mg or cilazapril 2.5 mg.

Results

Administered bisoprolol significantly decreased maximum (9.8 ± 0.5 cm/s versus 8.5 ± 0.6 cm/s; P < 0.05) and minimum (2.75 ± 0.19 cm/s versus 1.75 ± 0.27 cm/s; P < 0.02) velocity, increased the Pourcellot''s index (0.71 to 0.79; P < 0.05) in central retinal artery. There were no statistically significant changes in central retinal artery blood flow after administration of cilazapril.

Conclusion

Systemic application of beta-blockers may unfavourably disturb the ocular blood flow.     

Comparative Study of Recovery after Sevoflurane versus Halothane Anaesthesia in Adult Patients

Background

Induction and maintenance characteristics of sevoflurane and halothane have been studied, but little work has been done to compare the postoperative recovery of these two agents.

Methods

Sixty adult, ASA I and II patients were allocated randomly into Group A and Group B of 30 each. Group A received sevoflurane and Group B received halothane for maintenance. At the end of surgery early recovery, intermediate recovery and discharge criteria were assessed.

Results

Early recovery assessed with the mean time to extubation was 6.7 ± 2.29 min in Group A and 9.07 ± 1.64 min in Group B; eye opening was 7.28 ± 2.3 min in Group A and 10.6 ± 1.77 min in Group B; response to verbal command was 8.52 ± 2.83 min in Group A and 12.33 ± 2.17 min in Group B, while orientation was 10.43 ± 3.15 min in Group A and 14.77 ± 2.66 min in Group B. These differences were statistically significant (p<0.001). The mean time to reach post anaesthesia care unit discharge criteria was shorter for Group A (21.1 ± 4.69 min) as compared to Group B (27.43 ± 6.51 min) and this difference was statistically significant (p<0.001)

Conclusion

Early recovery time and time taken to achieve discharge criteria were faster with sevoflurane.Key Words: Sevoflurane, Halothane, Post-operative recovery     

Verapamil as an Adjunct to Local Anaesthetic for Brachial Plexus Blocks

Background

Calcium channel blockers potentiate the effects of local anaesthetics. We examined the effect of adding verapamil to local anaesthetic solution on anaesthetic duration in patients undergoing surgery under brachial plexus block.

Methods

This study was a prospective, randomized, controlled, double blind study. Sixty patients undergoing elective upper limb surgery were divided into two groups of 30 each. Group A received 40 ml of 1% lignocaine with 0.25% bupivacaine, while Group B patients had 2.5 mg verapamil added.

Result

Onset of sensory blockade time was marginally faster in Group B (23.2 ± 3.94 minutes) as compared to Group A (23.9 ± 4.13 minutes). However this difference was statistically not significant. The increase in duration of sensory blockade in Group B (185 ± 46.52 minutes) as compared to Group A (157 ± 44.28 minutes) was statistically significant (p= 0.011). Increase in duration of motor blockade in Group B (161 ± 46.14 minutes) as compared to Group A (149 ± 42,76 minutes) was statistically not significant (p = 0.15). Similarly prolongation of analgesic duration in Group B (318 ± 69.54minutes) as compared to Group A (302 ± 0.69 minutes) was statistically not significant (p=0.18).

Conclusion

We conclude that adding verapamil to brachial plexus block can prolong sensory anaesthesia without any effect on analgesic duration.Key Words: Brachial plexus block, Verapamil

Aim

The purpose of this study was to evaluate the semen profiles of bicycle taxi cyclists and healthy controls in Mangochi district, Malawi.

Methods

Semen samples were collected from young bicycle taxi cyclists after two to three days of sexual abstinence. A control group, comprising young men who were not bicycle taxi operators also submitted semen samples. Samples were left to liquefy for 30 minutes before measurements were conducted of volume, concentration, total motility, and progressive motility. This was followed by preparation of morphology slides. Light microscopy was used for sperm analysis.

Results

Semen parameters such as volume (1.66 ± 0.18 mL vs. 3.64 ± 0.17 mL; p = 0.0001), concentration (28.31 ± 4.33 x 106/mL vs. 54.95 ± 5.93 × 106/mL; p = 0.02) , total motility (56.98% ± 8.22% vs. 56.98% ± 8.22%; p = 0.03), progressive motility (22.57% ± 3.35% vs. 59.69% ± 4.82%; p = 0.004), and morphology (6.98% ± 3.23% vs. 19.73% ± 2.32%; p = 0.006) were significantly reduced in the bicycle taxi cyclists compared to the healthy controls.

Conclusion

In this case-control study, bicycle taxi operators had lower semen volume, concentration, total motility, and progressive motility, as well as a higher concentration of abnormally shaped spermatocytes, compared to healthy controls.

Closing-opening wedge osteotomy for thoracolumbar traumatic kyphosis

Background

Surgical treatment modalities for post-traumatic kyphosis (PTK) remain controversial. Like vertebral column resection, closing-opening wedge osteotomy (COWO) can achieve satisfactory results for kyphosis with multiple etiologies. However, few studies have assessed this procedure for PTK. Our purpose was to evaluate the radiographic and clinical outcomes of COWO in a selected series of patients with PTK via a single posterior approach.

Methods

In this retrospective case series, seven patients with symptomatic PTK in the thoracolumbar spine were reviewed. Five patients underwent surgery at the time of initial injury, and the other two initially underwent conservative treatment. All seven patients underwent COWO procedures through a single posterior approach. The Cobb angle was assessed preoperatively, postoperatively, and at the final follow-up. A visual analog scale (VAS) and the American Spinal Injury Association scale were used to evaluate back pain and neurological function preoperatively and at final follow-up, respectively. Operation-associated complications were also recorded.

Results

The mean follow-up period was 34.3 months (range, 24 to 43 months). The mean kyphotic angle was significantly (P <0.05) reduced from 57.7° (range, 36° to 100°) preoperatively to 8° postoperatively (range, −12° to 50°). The mean VAS improved from 5.9 to 2.1 (P <0.05). Three patients exhibited improved neurological function. Bony fusion was achieved in all patients. No significant correction loss or permanent complication was noted.

Conclusions

Though technically demanding, COWO via a single posterior approach can provide satisfactory outcomes for selected patients with PTK. Additional studies are required to improve patient selection and outcomes for this condition.     

Sonographic Biometry of Normal Kidney Dimensions among School-age Children in Nsukka,Southeast Nigeria

Background:

Some kidney diseases are usually associated with changes in kidney size.

Objective:

To determine sonographically the normal limits and percentile curves of the kidney dimensions according to age, gender and somatometric parameters among school-age children.

Methods:

A prospective cross-sectional research design and convenience sampling method were utilized. Participants included 947 normal subjects (496 boys and 451 girls) aged 6–17 years old. The sonographic examination was performed on a Shenzhen DP-1100 machine with 3.5 MHz convex transducer. Longitudinal and transverse dimensions of the kidneys were obtained in coronal plane with the subject in the supine or left lateral decubitus position.

Results:

The means of right and left kidney lengths in mm were 79.6 ± 8.1 and 81.6 ± 8.3, respectively while those of the right and left kidney widths in mm were 35.03 ± 3.6 and 35.09 ± 3.6, respectively. Dimensions of the kidneys were not statistically different in boys and girls (p > 0.05). There was a statistically significant difference between right and left kidney length (p < 0.05). Height correlated best with both kidney lengths. Thus the normal limits, prediction models and percentile curves of kidney lengths were established with respect to height.

Conclusion:

Sonographic determination of pathologic changes in the size of the kidney necessitates knowing the normal ranges of its length especially with respect to height in school-age children.     

Evaluation of in vitro aldose reductase inhibitory potential of different fraction of Hybanthus enneaspermus Linn F. Muell

Objective

To evaluate the aldose reductase inhibitory (ARI) activity of different fractions of Hybanthus enneaspermus for potential use in diabetic cataract.

Methods

Total phenol and flavonoid content of different fractions was determined. ARI activity of different fractions in rat lens was investigated in vitro.

Results

The results showed significant level of phenolic and flavonoid content in ethyl acetate fraction [total phenol (212.15±0.79 mg/g), total flavonoid (39.11±2.27 mg/g)] and aqueous fraction [total phenol (140.62±0.57 mg/g), total flavonoid (26.07±1.49 mg/g)] as compared with the chloroform fraction [total phenol (68.56±0.51 mg/g), total flavonoid (13.41±0.82 mg/g)] and petrolium ether fraction [total phenol (36.68±0.43 mg/g), total flavonoid (11.55±1.06 mg/g)]. There was a significant difference in the ARI activity of each fraction, and it was found to be the highest in ethyl acetate fraction [IC₅₀ (49.26±1.76 µg/mL)] followed by aqueous extract [IC₅₀ (70.83±2.82 µg/mL)] and it was least in the petroleum ether fraction [IC₅₀ (118.89±0.71 µg/mL)]. Chloroform fraction showed moderate activity [IC₅₀ (98.52±1.80 µg/mL)].

Conclusions

Different fractions showed significanct amount of ARI activity, where in ethyl acetate fraction it was found to be maximum which may be due to its high phenolic and flavonoid content. The extract after further evaluation may be used in the treatment of diabetic cataract.

A comparison between fibrin sealant and sutures for attaching conjunctival autograft after pterygium excision

Background

Use of conjunctival autograft following excision of primary pterygium has reduced the recurrence rate. This study evaluates the efficiency of fibrin glue as compared to sutures in attaching the conjunctival autograft with reference to surgical time, post operative comfort and recurrence during follow up.

Methods

60 patients with primary pterygium were included and divided into two groups. In the first group autograft was secured in place with help of 10-0 polyamide monofilament suture while in second group fibrin glue was used. Both the groups were compared in terms of operative time, post op comfort and recurrence.

Results

The average surgical time taken was 50.93 ± 4.96 min with suture group and 34.43 ± 4.94 min with fibrin glue group. Pain and foreign body sensation was markedly less with fibrin glue group. At the end of final follow up at 6 months, 3 cases (10%) from suture group and 1 case (3.33%) from fibrin group had recurrence.

Conclusion

Fibrin glue is effective and safe for attaching conjunctival autograft during pterygium surgery. Although more number of recurrences were observed in suture group as compared to fibrin glue group the difference was not statistically significant (p 0.612).
