How Important is the Tunnel Position in Outcomes Post-ACL Reconstruction: A 3D CT-Based Study

BackgroundDrilling the femoral and tibial tunnels at their anatomical locations are critical for good outcomes and involve seeing the footprints well. We intended to compare two techniques of drilling the tunnels and the patient-reported outcomes and knee stability of patients undergoing single bundle ACL reconstruction using 3D CT to evaluate if the tunnels were anatomical or not.Materials and MethodsSixty single bundle ACL reconstructions were analyzed, 30 each with Technique A and B. Pre-operative and after a minimum 27 month follow-up Lysholm, IKDC, Tegner score, hop test, and Lachman test were noted. 3D CT was done to classify femoral tunnels positions as being well placed, slightly or grossly misplaced and tibial tunnels as optimal or suboptimal and compared.ResultsSixty ACL reconstructions had full follow-up with a mean follow-up of 34 months. There was no significant difference between tunnel positions between the two techniques. Well-placed femoral tunnel had better Lysholm score (62.2 ± 16.2 v/s 48.5 ± 17.2, p 0.002) and IKDC score (62.5 ± 14.3 v/s 52.7 ± 15.1, p 0.012).). Those who had their surgeries within 3 months of their injury had better hop test (4.4 ± 0.9 v/s 3.9 ± 1, p 0.034) and IKDC scores (62.5 ± 15.8 v/s 33.2 ± 13.8, p 0.026) as compared to those that had surgery done after 3 monthsConclusionTibial tunnel positions were optimal in most cases and did not differ between the two techniques. Well-placed femoral tunnels and surgeries done within 3 months of the injury produced best results.     

Severe adverse cutaneous reaction to insulin due to cresol sensitivity

We present the case of an 80-year-old lady known to be sensitive to chlorocresol (4-chloro-3-methyl phenol) who developed severe erythrodermic exfoliative dermatitis with atypical features 2 weeks after commencing subcutaneous insulin. All medications except insulin were stopped, without major improvement. It was noted that the insulin contained m-cresol (m-methyl phenol) so a parabens-based insulin was substituted. There was a significant improvement in her clinical condition within 72 hr. Further patch and intradermal testing to the insulin and m-cresol was planned, but she developed a nosocomial infection and died. We hypothesize that the adverse cutaneous reaction was a systemic manifestation of cresol sensitivity, given the rapid clinical resolution on changing insulins and the previously demonstrated sensitivity to chlorocresol, particularly as cross-reactivity between different low molecular weight methyl phenols is documented. Local injection site reactions and systemic side-effects including nausea, diarrhoea and vomiting have previously been reported with cresol-containing insulins, although to our knowledge, this is the first reported case of a severe cutaneous reaction. It is important to be aware of m-cresol as a potential allergen, as it is contained in most commercially available insulins.

Periodontal disease and type 1 diabetes mellitus: Associations with glycemic control and complications: An Indian perspective

AimTo evaluate the frequency of periodontal disease in a group of patients with type 1 diabetes mellitus and its relationship with diabetic metabolic control, duration and complications.Materials and methodsA comparison was made of periodontal parameters (plaque index, bleeding index, pocket depth and attachment loss) in a group of diabetic patients versus a group of non-diabetics (n = 20). Statistical analysis was performed to evaluate the relationship between periodontal parameters and degree of metabolic control, the duration of the disease and the appearance of complications.ResultsDiabetics had greater bleeding index (p < 0.001), probing pocket depth (p < 0.001) and clinical attachment level (p = 0.001). Patients diagnosed for diabetes for shorter duration of time (4–7 years) showed bleeding index-disease severity correlation to be 1.760 ± 0.434.ConclusionPatients with type 1 diabetes have increased periodontal disease susceptibility. Periodontal inflammation is greatly increased in subjects with longer disease course, poor metabolic control and diabetic complications.     

Abnormal intestinal histology in neonates with congenital anomalies of the gastrointestinal tract

In animal models, when swallowing is experimentally prevented in utero, bowel length and weight are reduced, and villus height, crypt depth, and villus function are retarded. Little is known about the intestinal histology in infants with gastrointestinal (GI) tract anomalies. We examined the histological architecture of the intestine in neonates with GI anomalies in comparison to that of normal fetuses. Villus height, area, and length and crypt depth of normal fetuses were quantified in the proximal small bowel (n = 11) and measurements compared to those of surgical specimens of neonates with congenital anomalies of the GI tract (n = 16). Villus height and area and lamina propria height and area increased linearly from 8 to 24 weeks of gestation. In infants with anomalies of the GI tract, the villi were blunted and lacked normal histological architecture, the crypts were disorganized, and the crypt depth was significantly decreased (p = 0.004). Enterocyte height and area were significantly greater in neonates with congenital anomalies of the GI tract. The intestinal histology in neonates with congenital anomalies of the GI tract differs significantly from that of normal fetuses.
