We studied an experimental model of resection arthroplasty with or without tendon ball interposition in the wrist of dogs. Animals were divided into two groups. Animals in group A were treated by resection of the os carpi radiale with interposition of a ball made from the tendon of the extensor carpi radialis and the group B underwent bone resection alone. Animals were assessed 1, 6, 12 and 24 weeks after operation. In all of them the wrist joint was stable and had good mobility, allowing walking supported by the operated limb. In both groups biological material filled the cavity created by bone resection. A progressive repair process resulted in fibroplasia with areas of fibrocartilaginous metaplasia. The tendon ball showed complete ischaemic necrosis at the end of the first week, which delayed the healing process.

Connective Tissue Sheath

Deep cervical fascia forms a connective tissue sheath around the thyroid gland. Delicate trabeculae and septa penetrate the gland indistinctly dividing the gland into lobes and lobules which in turn composed of follicles.1,2,3 These follicles are structural units of thyroid gland which varies greatly in size and shape.4 The number of follicles varies in different age groups. The study was carried out to see the percentage of area occupied by follicles in the stained section of thyroid glands in different age groups. The collected samples were grouped as A (3.5 – 20yrs), B (21- 40yrs) & C (41 – 78yrs). Percentage of area occupied by follicles was (58.55±10.72) in group A, (63.79±12.35) in group B + (63.39±8.29) in group C.DOI: http://dx.doi.org/10.3329/updcj.v1i2.13981 Update Dent.

PURPOSE: To evaluate the healing process of a defect in the ventral abdominal wall of rats, comparing the polypropylene and polypropylene/poliglecaprone meshes on the 30th and 60th postoperative day. METHODS: Thirty two Wistar rats were submitted to a ventral abdominal wall defect, with integrity of the parietal peritoneum. In the repair, were used polypropylene (group A) and polypropylene/poliglecaprone (group B) meshes. The groups were subdivided into four subgroups of eight animals euthanized on the 30th (A30 and B30) and 60th postoperative day (A60 and B60). Fragments of the abdominal wall of the animals were submitted to macroscopic, tensiometric and histological evaluations. RESULTS: The tensiometry on subgroup A30 showed a mean average break point of 0.78 MPa and in A60, 0.66 Mpa. In subgroup B30 it was 0.84 MPa and in B60, 1.27 Mpa. The score of the inflammatory process showed subacute phase on A30 and B30 sub-groups and chronic inflammatory process in subgroups A30 and 60B. CONCLUSIONS: The tensile strength was higher on the wall repaired by polypropylene/poliglecaprone mesh in the 60th post-operative day. Histology showed higher concentration of fibrosis on the surface of the polypropylene mesh with a tendency to encapsulation. In polypropylene/poliglecaprone subgroups the histology showed higher concentration of fibrosis on the surface of mesh filaments.

Background: Infections in the foot are more common with significant proportion of world’s population remaining bare foot, minor skin trauma is a frequent cause of local infection. The present study was conducted with an aim to study various foot infections and compare the findings in diabetic and non diabetic patients with reference to etiopathogenesis, clinical features, management, duration of hospital stay and outcome.Methods: The present study was conducted in Mamata General Hospital, Khammam, Telangana state from October 2016 to September 2018. A total of 50 cases were divided into 2 groups, Group A included 25 patients with diabetic foot infection and Group B included 25 patients with non diabetic foot infections.Results: In diabetics 6th decade and in non-diabetics 4th-6th decade was the most common age group presenting with foot infections. Cellulitis of the foot was the most common in both diabetics (40%) and non-diabetics (52%). Wagner’s grade 4 lesions were more common in diabetics (28%) than in non-diabetics (8%). The most common site of lesion in diabetics was dorsum (40%) and in non-diabetics was toes (40%). The incidence of neuropathy was significantly higher in diabetics (72%) than in non-diabetics (20%). Rate of amputation was high in diabetics (12%) compared to non-diabetics (8%). The average number days in a hospital stay in diabetics was 42.27 days and in non-diabetics it was 28.96 days.Conclusion: Diabetic patients have increased severity of infections, delayed healing process, need more active interventions. As compared to the non-diabetic patients, they do show high risk of amputations and prolonged hospital stay.

A cross-sectional descriptive study was performed in the Department of Anatomy, Dhaka Medical College, Dhaka, from January to December 2008, on post mortem parathyroid glands of 60 Bangladeshi people in different age groups. A total of 207 parathyroid glands were identified in relation to posterior border of thyroid lobes and collected from those 60 cadavers. The samples were collected from the unclaimed dead bodies within 24 hours after death that were under examination in the Department of Forensic Medicine of Dhaka Medical College, Dhaka. The samples were divided into three different age groups ranging from 15 to 75 years. The three groups are group A (10-30 years), group B (31-60 years) and group C (61-90 years). From each group, 20 best prepared slides were taken for examination. The percentage volume of parenchyma (glandular portion) and stroma (fibrous part with blood vessels and fat) were estimated by the point counting technique with Zeiss-I integrating eyepiece under the light microscope at low magnification. The mean SD percentage volume of parenchyma varies 64.88 2.75 to 65.90 2.33 in group A, 56.40 12.57 to 59.10 3.87 in group B and 38.80 2.77 to 41.50 2.38 in group C. In contrast, the mean SD percentage volume of stroma varies 33.50 2.27 to 34.88 2.95 in group A, 40.30 3.83 to 41.56 4.16 in group B and 58.50 2.38 to 61.20 2.77 in group C. The percentage volume of connective tissue stroma was found to increase with increasing age with simultaneous decrease in glandular parenchyma.

This cross sectional, descriptive study was done in the Department of Anatomy, Dhaka Medical College, Dhaka from January to December 2009, to determine the proportion of cortex and medulla of the ovary in di_erent age group of Bangladeshi women. This study was based on collection of 140 ovaries of 70 unclaimed female dead bodies from the morgue of Dhaka Medical College, Dhaka. The samples were divided into three age-groups including A (10-13 years), B (14-45 years) & C (46-52 years). Histological slides were prepared by using routine haematoxylin and eosin stain. Ten best prepared histological slides from each age group were examined to determine the thickness of the cortex and medulla & proportion of the thickness of the cortex and the medulla of the ovary were expressed in percentages. The mean proportion of the cortex and the medulla of the right ovary were found 80.83±0.58% and 19.17±0.58% in group A, 86.95±1.14% and 13.05±1.14% in group B, 70.53±1.53% and 29.47±1.53% in group C respectively. The mean proportion of the cortex and the medulla of the left ovary were found 80.63±0.58% and 19.37±0.58% in group A, 86.78±1.14% and 13.22±1.14% in group B, 70.41±1.50% and 29.59±1.50% in group C respectively. The difference in mean proportion of the cortex and the medulla was not signi_cant in between the ovaries. However, the difference in mean proportion of the cortex and the medulla of the ovary between group A & group B, group A & group C and group B & group C were statistically significant.Bangladesh Med J. 2015 Jan; 44 (1): 8-10

Context: The human pineal gland is characterized by the presence of calcified concretions, called ‘pineal acervuli’ or brain sand. These are basophilic extracellular bodies. The study was carried out to describe the microscopic features of pineal calcifications and to find out age related changes. Study Design: Cross sectional descriptive type of study. Place and period of study: Department of Anatomy, Dhaka Medical College, Dhaka, from July 2009 to June 2010. Materials: 60 postmortem human pineal glands were collected from unclaimed dead bodies that were under examination in the morgue of Department of Forensic Medicine, Dhaka Medical College, Dhaka. Methods: The samples were divided into four different age groups, i.e. Group-A (15-30 years), Group-B (31-40 years), Group-C (41-50 years) and Group-D (>50 years). Histological study was carried out on relatively 27 fresh samples. Results: The mean diameter of the pineal calcifications were 351.14±111.69 ?m in group A, 600.00±232.69 ?m in group B, 909.43±124.18 ?m in group C and 1541.67±224.54 ?m in group D. The differences in diameter of the pineal calcifications between group A & C, A & D, B & C, B & D and C & D were statistically significant. Conclusion: Age related changes were found in the diameter of pineal calcifications. DOI: http://dx.doi.org/10.3329/bja.v9i2.15220 Bangladesh Journal of Anatomy 2011 Vol.9(2) pp.71-74

Purpose: to assess the efficacy of associating the microfracture technique with platelet-rich plasma (PRP) injections in the treatment of chondral lesions to promote acceleration and optimization of the healing process compared with the traditional microfracture approach. Methods: from September 2011 to August 2012, 20 patients (9 males and 11 females, aged 30-55 years) were treated. All presented with chondral lesions of the medial femoral condyle of the knee and a pain duration ranging from 8 to 12 months.The patients were randomized into two groups (A and B). Group A was treated with the microfracture technique and a total of three intra-articular injections of PRP. Group B was treated with microfractures alone. Clinical follow-up was performed at 3, 6 and 12 months after treatment. Clinical function was assessed on the basis of the International Knee Documentation Committee (IKDC) score. Pain was evaluated using a visual analogue scale (VAS) Results: the patients in group A had a mean baseline IKDC score of 31.2, which rose to 84.2 at 12 months. The IKDC scores in group B were at 30.1 at baseline and 81 at 12 months. Conclusions: the results of our study suggest that functional recovery and resolution of pain are obtained more quickly in PRP-treated patients. We also observed a better functional outcome in the patients treated with the combination of PRP and microfractures, even at 12 months, although the difference was not statistically significant. Level of evidence: level II, randomized clinical study.

The purpose of this study was to clarify the effect of an absorbable oxidised regenerated cellulose sheet (AORCS) for prevention of neural adhesion. Rabbit sciatic nerve was exposed at the middle of the thigh and the neural bed was coagulated by a bipolar coagulator to establish an adhesion model. Coagulation only was Group A (n = 8), coagulation and wrapping the sciatic nerve with an AORCS was Group B (n = 8), and an intact nerve was Group C (n = 16). Six weeks later, each group was estimated. Adhesion between the nerve and neural bed, and intraneural fibrosis were seen in Group A. However, there was little adhesion and fibrosis in Group B. Although the electrophysiological study showed a small significant difference, AORCS clearly prevented the adhesion in the histological study. Hence, AORCS might be useful as an additional treatment during nerve surgery.

The purpose of this study was to investigate the effect of xenogenic cortical bone (XCB) on fracture repair in the canine ulna. The entire group of animals (n = 12) had a transverse resection of 5 mm length at the middle part of the right ulnar diaphysis. In Group A (eight beagles), the fracture was treated with XCB and metal bone screw. In Group B (four beagles), the fracture was treated with metal bone plate and screw. Radiological, micro-computed tomography (micro-CT), histological examination and mechanical testing were employed to evaluate bone healing and reaction of XCB in the host bone. In Group A, bone union was noticed in 6 out of 8 dogs (75%), starting from the 4th week onwards. Micro-CT and histological examinations showed that the XCB was absorbed and incorporated into the host bone. Incorporation of XCB was observed in 7 cases (88%); it started from the 10th week onwards and continued to week 32 after surgery. Biomechanical strength of the bone fracture site was higher in Group A than in Group B, and was similar to that of normal bone. XCB enhances the bone healing process and can be used as absorbable internal fixation for the management of long bone fractures in dogs.
