Background: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy, which results from median nerve compression. A lot of nonsurgical modalities are available for the management of mild to moderate situations. Local Hyalase hydrodissection (HD) of the entrapped median nerve could offer a desirable sustained symptom alleviation. Objectives: To evaluate the clinical efficacy of Hyalase/saline solution carpal tunnel HD on pain, functional status, and nerve conduction in patients with CTS. Study Design: A randomized, double-blinded trial. Setting: Anesthesia, pain, and rheumatology clinics in a university hospital. Methods: Patients: 60 patients with CTS (> 6 months’ duration). Intervention: patients were allocated equally into either group 1 (HD with Hyalase + 10 mL saline solution injection), or group 2 (HD with 10 mL saline solution only). Measurements: assessment of pain using Visual Analog Scale (VAS), functional disability (FD) score, and nerve conduction studies before injection, and over 6 months after injection. Nerve conduction parameters before injection and postinjection by the end of 3 and 6 months were evaluated as well. Results: Statistically significant lower postinjection values of VAS (1 ± 1.8, 2 ± 1.1, 2 ± 1.2, 2 ± 1.1) in group 1 versus (2 ± 1.2, 3 ± 1.7, 4 ± 1.5, 5 ± 2.6) in group 2 by the end of the first week, and the first, third, and sixth months, and significantly lower FD scores (15.3 ± 1.2, 13 ± 1.3, 10.2 ± 1.3, 10.2 ± 1.3) in group 1 versus (17.5 ± 1.8, 16.6 ± 2.8, 19.4 ± 3.2, 21.2 ± 2.5) in group 2 during the same time intervals. Nerve conduction study parameters have shown significantly higher velocity and lower latency in the Hyalase group than in the saline solution group by the 3 and 6 month follow-up. Limitation: We suggest a longer period could be reasonable. Conclusions: Carpal tunnel HD with Hyalase with saline solution is considered as an efficient technique offering a rapid onset of pain relief and functional improvements, and better median nerve conduction in patients with CTS over 6 months follow-up duration. Key words: Carpal tunnel syndrome, Hyalase, median nerve hydrodissection

Anatomy And Physiology

Repetitive stimulation is a technique that evaluates the function of the neuromuscular junction. It is important not only in the detection, clarification, and follow-up of neuromuscular junction diseases, but also in excluding these disorders in patients with symptoms of fatigue, vague weakness, diplopia, ptosis, and malaise, or with objective weakness of uncertain origin. The technique requires knowledge of the physiology and pathophysiology of neuromuscular transmission and the basic techniques of nerve conduction studies. This chapter includes a brief review of the anatomy and physiology of the neuromuscular junction as it applies to repetitive stimulation, a detailed discussion of the technique, the pitfalls that can occur if not carried out correctly, criteria used to classify the results as normal or abnormal, the patterns of abnormalities that can be seen, and the clinical correlation of those abnormalities with the various different disorders of neuromuscular transmission.

First Time

A 36-year-old ulcerative colitis male patient on treatment for 7 years was referred to dermatology with resistant alopecia universalis and hypopigmented patches on limbs for 5 months. During this time he also reported to ophthalmology with acute bilateral decreased vision for 5 days. His examination revealed hyperaemic discs, multifocal retinal detachments and choroidal granulomas. Taking into account the revised diagnostic criteria, atypical course of disease in the form of early cutaneous presentation followed by ophthalmic manifestations was attributed to Vogt-Koyanagi-Harada syndrome (VKHS) which was supported by relevant investigations including ophthalmic imaging, MRI and nerve conduction studies. Subclinical nerve conduction abnormalities and white matter demyelination were also seen for the first time in a patient of VKHS. Appropriate treatment was required to prevent visual complications; therefore, systemic corticosteroids with steroid sparing immunosuppressive drug therapy showed significant improvement in vision on follow-up. Cutaneous manifestations were resilient to the entire regimen.

Uremic Patients

Figure: Background and Aims in Italy only a minority of uremic patients perform peritoneal dialysis (PD). In dialysis centers where PD is practiced and proposed the prevalence is no more than 23%. Proposed advantages of PD over HD are a more preserved Residual renal function (RRF), that has been associated with better survival, and better Quality of life (Qol) due to possible more preservation of previous lifestyle, independence, possibility of traveling, and flexibility. Incremental peritoneal dialysis is a promising way to further improve Qol and to preserve RRF. Lastly, PD is less expensive than HD. Aim of this study has been to retrospectively evaluate our ten-years experience of PD treatment on survival, dialysis adequacy, preservation of RRF and nutrition in uremic patients followed at our Dialysis Center. Method We retrospectively evaluated all the incident patients that started PD treatment due to uremia from 01-01-2008 to 31-12-2018 at the U.O. Nephrology ASST Spedali Civili of Brescia. The exclusion criteria were time of dialysis treatment less than 3 months and absence of previous dialytic treatment or kidney transplantation. For each patient anthropometric, clinical-anamnestic data and comorbidities at dialysis start were recorded. Data on dialysis adequacy, nutrition, RRF and PD dialysis modality performed were also recorded. Results During the observation period 329 patients started PD. 60 were excluded due to follow-up of less than 3 months. Therefore, 269 patients (males 160, 59%) were studied. The average age was 65±16 years, BMI 24±4 kg/m2. Comorbidities were: hypertension (87%), diabetes mellitus (32%), cerebral vascular disease (26%) and ischemic heart disease (25%). The mean duration of dialysis treatment was 2.1±1.5 years. At the end of ten-years follow-up 24% of patients have had a kidney transplant, 18% were on PD treatment, 17% have had a shift towards HD, 39% had died. The main causes of death were: infection (39%) and cardiovascular disease (31%). The most common dialysis modality performed was APD (61%); CAPD was performed in 39% of pts. Dialysis modality (CAPD; APD), nutrition parameters (PNA; BMI), as well as RRF, expressed as an average value during follow-up, are shown in Figure 1. 81 patients (30%) were treated with incremental PD; 85% of them with manual exchanges. The comparison of dialysis parameters between incremental PD and standard PD are shown in Figure 2. Multivariate analysis with survival as dependent variable (Figure 3), showed that age, diabetes mellitus, and low wKt/V were independently associated with an increased risk of mortality. Diuresis volume and male gender were protective factors. No independent influence on mortality of the dialysis treatment modality was found. Conclusion In this ten-years experience of patients undergoing PD at our Center, incremental PD seems to be a protective factor for the maintenance of a preserved diuresis and better dialysis adequacy, and these factors are associated with better survival of the patients.

Hand Symptoms

A retrospective study of 15 diabetic patients (20 hands), who underwent carpal tunnel release, was performed to determine the outcome. All patients had a minimum of 18 months of follow-up. Outcome was considered excellent if there was complete resolution of symptoms and this occurred in 35% of the treated hands. Eight hands (40%) had a good outcome with significant improvement of pre-operative symptoms. Outcome was considered poor when symptoms were minimally improved, unchanged, or worse after surgery and this occurred in 25% of treated hands. All hands with a poor final result had either no electrodiagnostic evidence of localized compression or only mild compression in pre-operative nerve conduction studies. It was postulated that the contribution of localized compression to pre-operative hand symptoms was less than the contribution of peripheral neuropathy in these hands.
