RESUMO

The tendo achilles is one of most important tendon in human body which often injured through direct trauma or indirect stress on a weakened tendon. Longer the duration after injury the injured parts likely to move apart, fibrosis and degeneration leading to difficulty in repair or reconstruction. Usually a phase of 4 weeks or more without specific treatment is regarded as chronic or neglected rupture. Different authors described many management protocols about the tendo achilles rupture but there is no procedure of choice for neglected rupture with long gap. Prospective case series of 21 patients of neglected tendo achilles rupture with long gap treated with flexor hallucis longus tendon (FHLT) transfer was taken for study from January 2019 to December 2020 in Mymensingh Medical College Hospital, Bangladesh. Average age of patients was 39.47 years with range 22-65 years. Fifteen (15) cases of traumatic rupture in this study with average age 32.66 years and pathologic 6 cases with average age 56.5 years were recorded. We grafted FHLT from channel by incising Henry's knot. Krackow et al.'s technique was followed for tendon mobilization and bone fixation. We made procedure simpler and cheaper; instead of using interference screw the sutured tendon pulled through the heel and anchored over rubber tube or button by Cole method. Post-operative complications were less with one patient with superficial infection which eventually recovered 3 cases of mild pain and 2 cases of numbness. Questionnaire for surgical outcome measure are satisfactory in 19 patients (90.47%). Final follow up AOFAS score at 6 month (91.61±5.41) was highly significant (p<0.001) in comparison to preoperative score (38.71±9.78). These are comparable to other study. Above mentioned scores indicate the reliability of the surgical system. But our study is a prospective case series with minimum cases. To establish the best procedure for neglected tendo achilles rupture with long gap we recommend further study with larger group and Randomized Controlled Trial (RCT) study among different procedure.

RESUMO

Intramedullary nailing is a pillar in the treatment of femoral shaft fractures. But it is not possible in all cases especially in comminuted fractures. This study has been designed to explain the importance of Minimally Invasive Plate Osteosynthesis (MIPO) with the locking plate in the treatment of comminuted Femoral Shaft Fracture. Twenty (20) such patients were treated by MIPO and analysis has been done in this study to get fruitful result and to find out the effectiveness of this procedure who were admitted at Mymensingh Medical College Hospital, Mymensingh, a tertiary level hospital of Bangladesh from February 2018 to January 2019. Mean age of the patients were 49.20±14.41 years. Based on AO classification, there were 4, 8 and 8 patients belong to type A, B and C respectively. The union period for all the patients was in between 12 to 14 weeks. The mean union period was 12.90±1.997 weeks. Mean follow up period was 19.70±2.77 weeks. Mean full weight bearing period was 16.50±1.10 weeks. In Thoresen scoring system excellent result was 9(45%), good result was 10(20%) and fair result was 01(5%). Mal-alignment happened in two cases. However, delayed union and broken screws were found in two cases each of which was treated accordingly. Comminuted Femoral shaft fracture with MIPO procedure is more effective treatment than intramedullary nailing. Furthermore, mal-alignment is the basic complexity that must be taken away intraoperatively.

RESUMO

Uterine fibroids often cause symptoms of pelvic pain, pressure, and bleeding and a significant cause of morbidity for women of reproductive age. A new, Food and Drug Administration approved noninvasive treatment option is magnetic resonance guided focused ultrasound surgery, which has the potential to become a treatment of choice for selected patients. The purpose of the study was to compare and evaluate the usefulness of MRI and transabdominal ultrasonography for the diagnosis of uterine fibroids. A cross sectional study was carried out in the department of Radiology & Imaging of Mymensingh Medical College Hospital, during the period of January' 2010 to December 2011. A total number of 40 consecutive patients having suspected uterine fibroids underwent MRI and transabdominal ultrasonography and they were followed up from the admission upto the tissue diagnosis of uterine fibroids for histopathological correlation were included in this study. The test of validity of MRI and transabdominal ultrasonography in diagnosis of uterine fibroids was calculated. In the diagnosis of uterine fibroids, USG was 88.2% sensitive, 66.7% specific, 85.0% accurate, 93.8% positive predictive values and 50% negative predictive values. However MRI was 97.1% sensitive, 83.3% specific, 95.0% accurate, 97.1% positive predictive values and 83.3% negative predictive values for prediction of uterine fibroids. The study shows that the MRI is more efficient diagnostic modality than transabdominal ultrasonography in detecting uterine fibroid presence and evaluation.

RESUMO

Breast cancer is the most common malignancy in women and the second most common cause of cancer-related mortality. The distinction by physical examination of physiologic nodularity from abnormal masses can be difficult, while the clinical differentiation of a malignant mass from a benign one is difficult; the medical as well as potential legal consequences of missing a palpable carcinoma are high. There are significant number of reported cases of false-negative findings on mammography and the great desire not to miss a malignant lesion in the early stage of disease lead to aggressive biopsy, but the biopsy rate for cancer is only 10.0% to 30.0%. This means that 70.0% to 90.0% of breast biopsies are performed for benign diseases, which induce unnecessary patients discomfort and anxiety in addition to increasing costs to the patient. Clearly, there is a great need for development of additional reliable methods to complement the existing diagnostic procedures to avoid unnecessary biopsy. This cross sectional study was carried out on 43 patients having palpable breast mass, attended in the Department of Radiology and Imaging Mymensingh Medical College Hospital, Mymensingh from 1st January 2012 to 31st December 2013 for the period of two year. These patients were evaluated by USG at the Department of Radiology and Imaging and histopathological examination at the Department of Pathology of the same College to confirm the diagnosis. In diagnosis of malignant mass by USG, 9(20.9%) cases were diagnosed as malignant and 34(79.1%) cases as other than malignant. Eight out of 9 were sonographically diagnosed as malignant lesions also proved as malignant lesion by histopathology and 1 other than malignant. Out of 34 sonographically diagnosed cases of other than malignant lesions 32 were proved histopathologically and 2 did not match with sonographic findings. USG, in diagnosis of malignant lesion, sensitivity was 80.0%, specificity 96.97%, positive predictive value (PPV) (88.89%), negative predictive value 94.12% and accuracy was 93.02% and comparable to other study. In diagnosis of benign lesion by USG, sensitivity was 96.97%, specificity 80.0%, positive predictive value (PPV) (94.12%), negative predictive value 88.89% and accuracy was 93.02%. So, USG is an appropriate imaging method for diagnosis & differential diagnosis of palpable breast mass.

RESUMO

A 50-year old, diabetic, hypertensive patient with post-CABG status developed complete loss of vision about one hour after coronary angiogram (CAG). Thorough ophthalmological and neurological examination as well as magnetic resonance imaging of brain especially of the occipital region revealed no abnormality. The patient had complete recovery of vision about 48 hours later. We could not document any specific cause or mechanism for the visual loss, although the selective vulnerability of occipital lobes to contrast agent toxicity (Cortical blindness) was the most likely underlying mechanism.

RESUMO

The mycotoxin sterigmatocystin (STC) is produced mainly by some Aspergillus and Penicillium fungi; it naturally contaminates cereals, peanuts, and products derived from these crops, and is both mutagenic and carcinogenic. As an intermediate of aflatoxin (AF) biosynthesis, its structure is similar to that of AF. Although immunoaffinity columns (IACs) are a popular approach to sample clean-up, no IAC is commercially available for STC, but a commercially available IAC for AF shows cross reactivity to STC. We here developed a new method for analyzing STC in grains using such an IAC and liquid chromatography mass spectrometry (LCMS), and validated this method using six different grains. The STC limit of detection (signal-to-noise ratio, S/N = 3) was 2.5 pg (1.0 µg/kg in the product), and the calibration curve was linear in the range of 7.5-375 pg (3.0-150 µg/kg in the product). The within-day recovery of STC from samples spiked with STC at 5.0 and 50 µg/kg was 83.2-102.5% and the RSDr (relative standard deviation of repeatability) of these samples was 1.9-6.5%; the RSDr of STC-pretreated grain samples was 3.1-14.0%. Average recovery of STC from samples spiked with STC in the range of 5.0-100 µg/kg STC was 83.2-102.5%, with an RSDr of 0.24-6.5%; the RSDr of STC-pretreated grain samples was 2.4-14.0%. In an intermediate precision study, the average STC recovery from STC-spiked samples by three analysts was 95.2-107.5%, with RSDRi (intermediate precision) of 4.0-7.1%; the RSDRi of the STC-pretreated samples was 4.8-10.4%. Thus, the proposed method was effective for STC analysis in grains, and holds potential for a novel application of a commercial IAC, intended for AFs, in STC analysis.

RESUMO

A significant number of paediatric surgical patients undergone clean surgical procedures. Most of the paediatric surgeon use perioperative prophylactic antibiotic in this clean procedure because of undue fear of infection in their mind. The objective of this study is to evaluate whether the use of perioperative prophylactic antibiotics have an effect to prevent post operative wound infection in clean operation in paediatric surgical patients. This study was conducted in the paediatric surgery department of Bangabandhu Sheikh Mujib Medical University and some private clinics of Dhaka city from January 2009 to December 2009. Two hundred patients who were undergone clean elective surgical procedure on day case basis were included in this study. They were divided into two equal groups (Group A and Group B). The patients of Group A were given intransverse Cephradine 30 minutes before incision and then oral Cephradine was advised postoperatively for 7 days. The patients of Group B were not given any perioperative antibiotic. All the patients of both groups were advised to come on 3rd, 6th and 10th postoperative day for examination of wound. In Group A (With chemo prophylaxis), five patients (5%) developed postoperative wound infection and in Group B (without chemo prophylaxis), three patients (3%) developed postoperative wound infection. Thus the rate of postoperative wound infection is slightly more in patients with chemo prophylaxis but it was not statistically significant by chi-square test. Based on the result of this study, it may be concluded that the antibiotic prophylaxis is not necessary in clean surgery in paediatric age group.

RESUMO

Congenital bladder diverticula (CBD) are unusual but not rare in childhood. Report of acute urinary retention due to congenital bladder diverticula are rarely found in the literature. Here we report a case of congenital bladder diverticulum with acute urinary retention in a ten months old male infant. Urinary tract infection and urinary retention are the most frequent presentation forms. In this case CBD produce urinary obstruction as a result of compression of the urethra which causes urinary retention. Voiding cystourethrogram revealed a large bladder diverticulum. Bladder diverticulum should be a differential diagnosis in male children, presenting with urinary retention, fever and an abdominal mass. Ultrasonography, voiding cystourethrogram & cystoscopy confirm the diagnosis and diverticulectomy was successfully done for the child.

RESUMO

Melanotic neuroectodermal tumour in infancy is rare, mainly benign with little tendency to recur after excision or effective curettage. This pigmented neoplasm of neural crest origin occurring in infants before 1 year of age. The most common site of occurrence is the anterior maxillary alveolar ridge (70%), following by the skull, brain and mandible. The genital organ is the most frequent extra cranial site. We report a 6 months old male baby with a similar tumour arising from right half of cheek involving the maxilla. We diagnosed the case after histological report. We remove the tumour through a sub-labial incision. The mass was blackish in colour, and was mobilized from all side including from the maxillary sinuses. The author thought that this should be reported for improving the clinical awareness and treatment of pigmented soft tissue mass in children. Almost one year follow up of the patients showed no recurrence.

RESUMO

Congenital Muscular Torticollis (CMT) is a postural deformity of head and neck detected at birth or shortly after birth, primarily resulting from unilateral shortening of Sternocleidomastoid Muscle (SCM). In neonates and infants, patient may cure conservatively by physiotherapy but surgery is the treatment of choice for children and adolescents. There are various techniques of surgery. Here we show our experience regarding management of congenital muscular torticollis. In the present retrospective case series, fourteen patients of congenital muscular torticollis were treated. The cases were enrolled between Nov' 2005 to Oct' 2007 in Bangabandhu Sheikh Mujib Medical University, Gonosasthaya Somaj Vittik Medical College Hospital, Dhaka and different private clinics of Dhaka city of Bangladesh. Neonates and infants were treated conservatively with physiotherapy and others treated surgically by transection of both sternal and clavicular head of SCM under general anesthesia. Operated patients were released on following post operative day with advised to do physiotherapy. Patients age range from 7 days to 15 years of which ten were female and four male. SCM was shortened in all cases (8 on right side and 6 on left side). Eleven were female and three male. Of 14 patients, 2 neonates, 7 infants and 5 were more than 1 year age. There was no associated anomaly. Out of 9 neonates and infants 8 cured conservatively with physiotherapy and another one significantly improved. Six were treated surgically including one failed physiotherapy. Post operative period was uneventful and there was no complication. Results were evaluated clinically and comments of peers. Most of the patient of congenital muscular torticollis can be treated conservatively during infancy. Division of both sternal and clavicular head of SCM is easy and safe surgical technique for the treatment of CMT of older children and adolescents.

RESUMO

This prospective study was done to evaluate the result of interlocking intramedullary nailing in fracture shaft of the femur under the Department of Orthopaedic Surgery in Mymensingh Medical College Hospital during the period of January 2007 to December 2008. In this study total 66 patients were purposively selected for interlocking nailing initially but 6 patients did not report in subsequent follow up. So, the result of the study was based on 60 patients. There were 38 males and 22 females with the age range of 18 to 70 years, with an average age of 34 years. Motor vehicle accident was the most common cause of the fracture shaft of the femur (60%) and the second most common cause was fall from height (20%). Right sided involvement was more (66.67%). Majority of the patients had fracture lower third of the femur (70%). Among the patients farmer was the most common (33.33%) group and the next was housewife. The mean union time was 17 weeks with the range of 14 to 30 weeks. Postoperative complications were found, such as infection (3.33%) and nonunion (1.66%). The functional outcome of this study was evaluated by Klemm & Borner criteria. Excellent functional outcome was found in 80%, good in 15% and fair in 5%.

RESUMO

BACKGROUND/AIMS: Microorganisms of Peptostreptococcus micros are asaccharolytic, anaerobic gram-positive cocci that are frequently isolated from human oral sites such as periodontal pockets. Preliminary study showed that several amino acids, including serine, enhanced slightly the growth of P. micros. Therefore, we investigated the degradation of serine and serine-containing oligopeptides. METHODS: Metabolic end products were determined with high-performance liquid chromatography. The related enzymatic activities in cell-free extract were also assayed. RESULTS: Washed P. micros degraded serine-tripeptides (Ser-Ser-Ser), and produced formate, pyruvate, acetate, and ammonia. They also degraded serinyl-tyrosine (Ser-Tyr) to the same products. Related enzymatic activities, such as serine dehydratase, pyruvate formate-lyase, formate dehydrogenase, pyruvate oxidoreductase, phosphate acetyltransferase, and acetate kinase, were detected in the cell-free extract, indicating that the organisms produced ATP in the serine metabolism. CONCLUSION: P. micros utilized serine-containing oligopeptides as exogenous metabolic substrates rather than serine itself, and degraded Ser-Ser-Ser and Ser-Tyr to formate, pyruvate, acetate, and ammonia with ATP generation.

RESUMO

A cross sectional descriptive type of study was done in 98 women of reproductive age. Among them 25 were in control group of non pregnant women and 73 were pregnant women of 1st, 2nd and 3rd trimester of pregnancy with and without iron supplementation. The period of study was July 2004 to June 2005. The main objective of our study was to compare serum iron and total iron binding capacity in pregnant and non pregnant women. In present study serum iron was significantly increased in 2nd and 3rd trimester of pregnancy that was supplemented with iron when compared with the same category of women who were not supplemented with iron. On the other hand serum total iron binding capacity (TIBC) was significantly increased in 3rd trimester of pregnancy that was not supplemented with iron when compared with the same category of women who were supplemented with iron. It is evident that the significantly low serum iron and high TIBC in pregnant women is due in part to dietary iron deficiency. Therefore, iron therapy in pregnancy is helpful to maintain the serum iron and TIBC nearer to that of non pregnant normal women.

RESUMO

The present study was undertaken to estimate serum cortisol level in control experimental groups in Bangladeshi people. For this purpose a total number of 55 subjects of age range (18-55) years were selected from Mymensingh Medical College Hospital during July 2003 to June 2004. Subjects included in this study were divided in to two main groups: control (n=13) and experimental (n=42). According to different types of stress the experimental group was further divided in to four subgroups: infection, psychiatric, pre and post surgery. Blood samples were collected from all subjects with aseptic precautions at 8 AM and serum cortisol concentration was measured by Radioimmunoassay method. Statistical analyses were done by using Student's 't' test. A distinct and statistically significant increased serum cortisol level was observed in infection, psychiatric disorders and post surgical group in comparison to control group (P< 0.001). While no significant difference was observed in pre surgery when compared to that of control group.

RESUMO

Holmium YAG laser is one of the new modalities of treatment of urinary bladder tumor. Thirty patients of superficial bladder carcinoma were selected from the Urology out patient department of Dhaka Medical College Hospital from January 2004 to July 2004. Among thirty cases, 18 were recurrent and 12 were primary superficial bladder carcinoma. Out of thirty patients, 24 were male and six were female. Patients were treated with Holmium YAG laser under spinal anesthesia. Before resection, cold cup biopsy were taken from the apex and after resection of the tumor, another cold cup biopsy were taken from the base of the tumor. Holmium YAG laser therapy was given with a 550 micron end firing quartz laser fiber through the working element of resectoscope. Small tumors (< 1 cm) were ablated and large tumors (1-4 cm) were resected. The initial laser setting was 0.5 to 0.8 J and 10 Hz. For resection of the tumor, a slightly higher energy of 1 to 1.2 J was used at 10 to 12 Hz. After resection, bleeding vessels were coagulated. The resected tumor was evacuated by Elik's evacuator. All cases were followed for 6 to 12 months by history, physical examination, urine analysis, sonogram and cystoscopy three monthly. Bleeding was minimum during the procedure and no transfusion was required. Complications like obturator jerk, clot retention or perforation were not developed. No recurrence was found during the 6 to 12 months follow up period. The procedure was found safe, effective, and acceptable. The study was conducted to evaluate the initial result of Holmium YAG laser for the treatment of superficial bladder carcinoma. We warrants further studies in this regard.

RESUMO

The present study was done to determine the serum C-reactive protein (CRP) concentration in normal subjects and patients suffering from infection, psychiatric disorders and of surgery. A total number of 55 subjects within 18-55 years age were selected from Mymensingh Medical College Hospital during the period from July 2003 to June 2004. Normal subjects as control were 13 and 42 comprised the group experimental. According to different types of stress the experimental group was further divided in to four subgroups: infection, psychiatric, pre and post surgery. Serum CRP concentration was measured by Immunoturbidimetric method from each subject. Statistical analyses were done by using Student's ' t' test. Statistically significant rise of serum CRP was observed in infection, psychiatric disorders and post surgery group in comparison to control group (P< 0.001). The study indicated that subjects with infection, psychiatric disorder and post surgery stage were in stressful conditions that resulted increased synthesis of CRP by liver cells due to Hypothalamopituitaryadrenal (HPA) axis hyperactivity and immune mediated inflammation.

RESUMO

Previous studies demonstrated that hydrogen peroxide (H(2)O(2)) is a tumor promoter in the rat liver epithelial cell line T51B. We investigated the pathway linking H(2)O(2) to tumor promotion. H(2)O(2) can directly induce tyrosine phosphorylation of epidermal growth factor receptor (EGFR). H(2)O(2) and epidermal growth factor exerted similar effects on the induction of early growth response genes, disruption of gap junction communication, triggering of calcium inflow, and promotion of transformation. Furthermore, the effect of H(2)O(2) on tumor promotion was blocked by abrogation of EGFR activation. Our results suggested that tumor promotion by H(2)O(2) is mediated mainly through activation of EGFR in T51B cells.

RESUMO

Stable re-expression of connexin 43 (cx43) in human glioblastoma suppresses transformation and tumorigenicity. The present study was designed to examine the role of cx43 in chemotherapy-induced apoptosis. Expression of cx43 in human glioblastoma cells significantly increased sensitivity to several common chemotherapeutic agents, including etoposide, paclitaxel (Taxol) and doxorubicin, compared with control-transfected cells. The increased sensitivity to chemotherapeutic agents resulted from apoptosis as evidenced by Hoechst dye staining, TUNEL assay and annexin V assay. These cx43-mediated effects were coupled with decreased expression of the specific apoptosis inhibitor bcl-2. Over-expression of bcl-2 in cx43-transfected cells partially confers the resistance to apoptosis induced by etoposide, suggesting that the cx43-mediated apoptosis to chemotherapeutic agents is regulated in part through the down-regulation of bcl-2 expression. Furthermore, the cx43-mediated apoptosis in response to chemotherapeutic drugs may not be linked to increased gap junctional communication in cx43-transfected cells. Our results demonstrate a new role of cx43 in the mediation of apoptosis during chemotherapy.

RESUMO

Reactive oxygen species, including H2O2, play an important role in the tumor promotion process. Using an in vitro model of tumor promotion involving the rat liver epithelial oval cell line T51B, the tumor promoting activity of H2O2 in N-methyl-N'-nitro-N-nitrosoguanidine-initiated cells was studied. In this assay system, the promoting effect of H2O2 is evidenced by the formation of colonies in soft agar, appearance of foci in monolayer culture, disruption of gap junction communication (GJC) in foci areas and growth at higher saturation densities. H2O2 preferentially induced the expression of c-fos, c-jun, c-myc and egr-1, while JunB and JunD levels remained almost unchanged. H2O2 also induced hyperphosphorylation of Cx43 and disruption of GJC. The effects of H2O2 on tumor promotion, induction of immediate early (IE) genes and disruption of GJC are blocked by antioxidants. These results suggest that H2O2 acts as a tumor promoter in rat liver non-neoplastic epithelial cells and that the induction of IE genes and disruption of GJC are two possible targets of H2O2 during the tumor promotion process.
