Salivary composition in diabetic patients.

Salivary composition and flow rate were examined in 35 patients with insulin-dependent diabetes mellitus (IDDM) and compared to 31 healthy controls. Significantly lower whole-saliva flow rate was observed in the IDDM patients, but was not correlated with the subjective complaint of xerostomy. Glucose concentration was significantly higher in the parotid saliva of the IDDM patients. Potassium concentration was significantly higher in whole and parotid, resting and stimulated saliva, as was total protein concentration in resting whole and in stimulated parotid saliva of the diabetics. No significant difference between diabetics and healthy controls was found in sodium and IgA concentration or in amylase activity. The significantly higher glucose, lower flow rate, and higher potassium and protein concentrations indicate that salivary glands are affected in IDDM. The subjective complaint of dry mouth, often present in diabetics, while not correlated with salivary flow rate, might reflect qualitative changes in salivary composition and/or altered mucosal perception. Salivary glucose concentration, although significantly higher in the diabetics, was not significantly correlated with serum glucose, preventing the use of saliva for monitoring blood sugar.

Oral health and salivary composition in diabetic patients.

The salivary composition and flow rate were examined in 20 patients with insulin-dependent diabetes mellitus (IDDM) and in 19 patients with non-insulin-dependent diabetes mellitus (NIDDM) and compared with 20 healthy controls. Resting and stimulated whole and submandibular saliva was analyzed. Significantly lower resting salivary flow rates were found in the IDDM patients as compared to the NIDDM group. In the IDDM patients potassium concentration in resting saliva was significantly higher compared with healthy controls and in stimulated whole saliva compared with NIDDM patients. No difference in salivary total protein, amylase, lactoferrin, or lysozyme was found among the three groups examined. The IgA concentration of the IDDM patients was significantly higher in whole resting saliva compared with controls and in the submandibular saliva compared with both NIDDM patients and controls. No difference was found between controls and the diabetic patients examined in prevalence of complaint of dry mouth. The salivary flow rates, however, were significantly lower in the three subgroups with dry mouth compared with the subgroups without this complaint. Caries were detected in 100% of the diabetic patients and controls. No correlation was observed between the incidence of caries and any of the salivary parameters examined. A higher prevalence and severity of periodontal disease was detected in the diabetic patients as compared to the controls. A significant positive correlation was found between the gingival index and the concentrations of total protein, albumin, lysozyme, and lactoferrin in whole resting saliva in the three groups examined.

Outcome of trigger finger treatment in diabetes.

Trigger finger is an underdiagnosed hand disorder causing disability in longstanding diabetic patients. Sixty diabetic patients [39 insulin-dependent diabetes mellitus (IDDM) and 21 non-insulin-dependent diabetes mellitus (NIDDM)] and 60 nondiabetic patients were examined. All were initially treated by steroid injections: failure to alleviate symptoms was the indication for surgery. The incidence of multiple digit involvement was higher in IDDM patients as compared with the control group (p < 0.001). The diffuse type was 1.45 times more frequent in IDDM and NIDDM than in nondiabetic patients (p < 0.008). The diabetic patients had a relatively longer duration of symptoms (p < 0.003). Significantly, a higher recovery rate upon steroid injection was achieved in control patients as compared with the diabetic ones (p < 0.001). IDDM patients required more surgery compared with NIDDMs and, in 13.3% of diabetic patients, the surgical outcome was not successful. Diabetic patients should be diagnosed early for multiple and diffuse types of trigger digits. Steroid injection as the first mode of therapy is highly recommended although not always successful. Surgery is the definitive treatment but requires a long course of physiotherapy and may be associated with some complications.

Auditory brainstem evoked potentials in insulin-dependent diabetics with and without peripheral neuropathy.

Auditory Brainstem Evoked Potentials (ABEP) were recorded from 33 insulin-dependent diabetes mellitus (IDDM) patients (17 with diabetic peripheral neuropathy and 16 without) as well as from 20 normals. Pure-tone audiometry, speech reception threshold and discrimination were also evaluated. Sub-clinical pure-tone threshold elevation was observed for IDDM patients with neuropathy. Pure-tone thresholds of IDDM patients without neuropathy were not significantly different from those of normals. ABEP abnormality (at 10/sec click rate) was observed in 31% of IDDM patients with neuropathy, rising to 44% when 55/sec click rate measures were included. Abnormalities included bilateral and symmetrical peak-latency prolongations for all waves, greater for the later waves, and prolongation of V-I and V-III interpeak latency differences, all at 10/sec, and only prolonged peak latency for I at increased rate. Abnormalities coincided with microangiopathy and peripheral neuropathy. The incidence of ABEP abnormality for IDDM patients without neuropathy was only 12%, unilateral and sporadic in nature. As a group, IDDM patients with neuropathy had significantly prolonged IV and V peak-latencies, compared with the normals, or with the IDDM patients without peripheral neuropathy. In contrast, IDDM patients without neuropathy resembled the normals in all respects. ABEP have proven useful in understanding the variety of pathologies underlying the clinical manifestation of diabetes.
