ENDOMETRIOMA OF THE LIVER

Hepatic endometriosis is extremely rare. The diagnosis is often missed and treatment is delayed. A 37-year-old woman was referred to the gynaecology department with vague abdominal pains. She had a past history of pelvic endometriosis and hysterectomy with bilateral salpingo-oophorectomy. Further investigations in due course confirmed it to be endometriosis of the liver. She was eventually referred to the hepatobiliary unit, almost three years after her first presentation, where she was operated on with good results.     

Effects of lathyritic drugs and lathyritic demineralized bone matrix on induced and sustained osteogenesis

Demineralized bone matrix was implanted in normal and lathyritic rats. At 2 weeks, the bone that formed in the lathyritic animals had an elevated alkaline phosphatase activity and a reduced calcium content compared with the controls. Four weeks after implantation, these biochemical parameters were reversed, with a decrease in alkaline phosphatase activity and an increase in calcium content to control levels. the histology of the recovered implants revealed new bone formation. Lathyritic demineralized bone matrix was prepared from bones of rats fed β-aminopropionitrile for 2 weeks (2-week BAPN-DBM) or 4 weeks (4-week BAPN-DBN), and was implanted in normal rats. Two weeks after implantation, both preparations of lathyritic demineralized bone matrix demonstrated early bone formation, although alkaline phosphatase activity and calcium content were reduced. By 4 weeks after implantation, no biochemical or histological evidence of bone formation remained at the site of the 4-week BAPN-DBM implants; continued but reduced bone formation was observed at the site of the 2-week BAPN-DBM implants. Reconstitution of inactivated normal demineralized bone matrix with the guanidine-soluble extracts restored the osteoinductive capacity. However, reconsistution of inactivated lathyritic demineralized bone matrix (4-week BAPN-DBM) failed to restore the osteoinductive capacity. These results indicate that the degree of crosslinking of the collagen matrix that acts as a carrier for osteoinductive proteins plays a key role in inducing and sustaining osteogenesis.     

Increased number of substitutions in the D-loop of mitochondrial DNA in the sudden infant death syndrome

The purpose of the present study was to investigate substitutions in the D-loop of mitochondrial DNA (mtDNA) in sudden infant death syndrome (SIDS) and controls, since several observations indicate the involvement of mtDNA mutations in SIDS. These include elevated levels of vitreous humour hypoxanthine in SIDS victims, familial clustering without mendelian traits, and observations of increased sleepiness and a lower activity score in infants who later succumbed to SIDS. Eighty-two cases of SIDS and 133 controls were investigated and the D-loop sequences were recorded in the base-pair range 16 055-16 500 in the mtDNA sequence. The sequencing was carried out using the Applied Biosystems Sequenase dye terminator method and a ABD373A sequencer. The recorded D-loop sequences were compared with the Cambridge sequence and differences were recorded as substitutions. The SIDS cases had a tendency towards a higher substitution rate in the D-loop than the controls ( p = 0.088). This observation makes it interesting to search for deleterious mutations in other locations in the mtDNA.     

Evaluation of scleral incisions and their effects on corneal curvature in manual small-incision cataract surgery

Purpose:Incisions in cataract surgery can be modified in various ways in terms of size, shape, and axis to reduce or tailor astigmatism. This study was conducted to examine the effect of site (superior vs, temporal) and shape (frown vs. V-shaped, chevron) of scleral incisions for cataract surgery on corneal curvature.Methods:The prospective study was carried out on 200 consecutive patients with senile cataract and who were planned for surgery at a tertiary eye hospital in north India. The placement of the incision was decided by the steeper corneal meridian—whether superior or temporal—and then patients of these two groups were randomized for frown and V-shaped incision; in this way, four groups of 50 patients each were formed. Follow-up was done on day 1, at 2 weeks, 4 weeks, 8 weeks, and 12 weeks. At each follow-up, post-operative keratometry with routine postoperative examination was done. The results were statistically analyzed by using student’s t-test, Chi-squared test, and the Pearson correlation coefficient.Results:In all the four groups, the difference of preoperative astigmatism and surgically-induced astigmatism was statistically highly significant. The analysis of uncorrected visual acuity (UCVA) was statistically significant (P < 0.05) on postoperative day 1 and at 2, 4, and 12 postoperative weeks; it was statistically insignificant (P > 0.05) at postoperative week 8.Conclusion:Temporal incisions result in lesser postoperative surgically induced astigmatism (SIA) than superior incisions. Chevron incisions result in minimal change in corneal curvature. This effect can be utilized to tailor the postoperative astigmatism.     

Anxiety and depression levels of healthcare workers during Covid-19 pandemic

BackgroundCoronavirus disease 2019 (covid-19), which causes a pandemic in the world, has started to appear in turkey since march 2020. Healthcare workers are at the top of the groups most at risk for covid-19 infection, which can have a negative impact on psychological state.ObjectivesIt was aimed to evaluate anxiety and depression levels among healthcare workers.Methodsthis cross-sectional study performed via an online survey in april 2020. Participants answered questions about sociodemographic features, personal views and experiences about covid-19 and the hospital anxiety and depression scale (hads).ResultsA total of 300 healthcare workers,193 men and 107 women, participated in the survey. According to hads, 44.6% of participants scored above anxiety and 68.2% scored above depression cut-off points. Being younger than 50 and taking care of covid-19 patients in hospitals were independently associated with anxiety risk. Female gender, young age (less than 50) and having comorbidity were independent risk factors for depression.ConclusionHealthcare workers were at high risk of anxiety and depression during covid-19 outbreak. For this reason, psychological support should be given, especially to the group with high risk.     

Single‐port appendectomy in obese children: an optimal alternative?

Introduction: The aim of this study was to evaluate our experience with single‐port appendectomy (SPA) in obese children. Methods: From January 2003 to June 2009, 94 SPA (65 women and 29 men, mean age of 12.4 years) were performed in children with appendicitis. Sixty‐five of these patients were found to have normal weight, whereas 29 were obese. Patients’ records were evaluated regarding operative time, intra‐ and post‐operative complications, initiation of oral intake and histopathological findings. Results: There was no significant difference in operative time between obese and normal weight patients. In the obese group, one wound healing disturbance was documented. In the normal weight group, there were one post‐operative bleeding and one wound infection. There was no difference with regards to the introduction of feeds following appendectomy between the groups. Histological examinations revealed 15 normal, 32 acute, 21 phlegmonous, 20 chronic and two perforated cases of appendicitis, three neurogenic appendicopathies and one case of enterobius vermicularis related appendicitis. Conclusions: Our results indicate that the advantages of single‐port appendectomy in the evaluation of the peritoneal cavity, the minimal rate of intra‐operative incidents with this technique and superior cosmetics validate this alternative approach of minimal access appendectomy in obese children.     

Successful Treatment of Bone Marrow Failure in Gaucher's Disease with Low-dose Modified Glucocerebrosidase

We report the beneficial effects of enzyme replacement therapywith mannose-terminated human glucocerebrosidase (‘Ceredase’)in a patient suffering from transfusion-dependent bone marrowfailure due to Gaucher's disease. Treatment with low-dose enzymeinfusions, given twice weekly, rapidly reversed the haematopoieticfailure and incapacitating skeletal disease. It appears likelythat prior splenectomy favourably influenced the response tothis therapy.
