Oversewing the Staple Line: Does It Safe to Prevent Leakage?

Introduction: The staple line (SL) leak remains one of the most serious complications after laparoscopic sleeve gastrectomy (LSG). The present study aims to determine whether reinforcing the SL with sutures is effective in maintaining tissue integrity. Materials and Methods: LSG Specimens of 60 patients were ex vivo studied. The specimens were divided into three groups: In group 1, the entire SL was reinforced, while the upper half part of the SL was reinforced from fundus to antrum in group 2. The SL was not reinforced in group 3. Then, the pressure inside the sample was increased, and the bursting pressure location and pressure value during the bursting were recorded. Results: The bursting pressure was significantly higher in entire and half oversewed SL groups than the none reinforced group (group 1: 115 mmHg [95-170]; group 2: 95 mmHg [80-120]; group 3: 40 mmHg [22-60], respectively, [P < .001]). The most common site of bursting was in the middle ⅓ of SL (35, 53.8%), followed by the proximal ⅓ part of SL (18, 27.7%), and the distal ⅓ part of SL (12, 18.5%), respectively. The bursting site was significantly more frequent in the corpus than the other parts of the SL (P = .013). Conclusion: Reinforcing the SL with sutures preserves tissue integrity. Although bursting was most frequently observed in the corpus region ex vivo, the fact that almost all real-life leaks develop in the area close to the Angle of His. This situation suggests that strengthening the suture line with reinforcement alone will not be protective enough against leaks in the fundus line, and factors such as tissue ischemia may be considered.

Comparison of open and laparoscopic gastrectomy for gastric cancer: a low volume center experience

Objectives

In gastric cancer, laparoscopic gastrectomy is commonly performed in Asian countries. In other regions where tumor incidence is relatively low and patient characteristics are different, developments in this issue have been limited. In this study, we aimed to compare the early results for patients who underwent open or laparoscopic gastrectomy for gastric cancer in a low volume center.

Material and Methods

We retrospectively analyzed the data of patients who underwent curative gastric resection (open gastrectomy n: 30; laparoscopic gastrectomy n: 30) by the same surgical team between 2014 and 2019.

Results

The tumor was localized in 60% (36/60) of the patients in the proximal and middle 1/3 stomach. In laparoscopic gastrectomy group, the operation time was significantly longer (median, 297.5 vs 180 minutes; p <0.05). In open gastrectomy group, intraoperative blood loss (median 50 vs 150 ml; p <0.05) was significantly higher. Tumor negative surgical margin was achieved in all cases. Although the mean number of lymph nodes harvested in laparoscopic gastrectomy group was higher than the open surgery group, the difference was not statistically significant (28.2 ± 11.48 vs 25.8 ± 9.78, respectively; p= 0.394). The rate of major complications (Clavien-Dindo ≥ grade 3) was less common in the laparoscopic group (6.7% vs 16.7%; p= 0.642). Mortality was observed in four patients (2 patients open, 2 patients laparoscopic).

Conclusion

In low-volume centers with advanced laparoscopic surgery experience, laparoscopic gastrectomy for gastric cancer can be performed with the risk of morbidity-mortality similar to open gastrectomy.

Laparoscopic Surgery for Adult Intussusception: Case Series

BACKGROUND/AIMS

Intussusception is a rare condition in adults which accounts for 1% of all intestinal obstructions. It usually requires surgical treatment and the classic approach is laparotomy. This article presented six adult patients who underwent laparoscopic surgery for intestinal obstruction due to intussusception.

MATERIALS AND METHODS

Between January 2017 and July 2019, six adult patients underwent laparoscopic surgery for intestinal obstruction due to intussusception. The patients were evaluated in terms of presenting symptoms, diagnosis, treatment modality, morbidity, mortality and histopathological results.

RESULTS

All patients presented with acute (50%) or subacute (50%) symptoms. All patients had intestinal obstruction (partial, complete) findings. Intussusception was diagnosed by abdominal computed tomography (CT). The patients with ileocolic and colo-colonic intussusception underwent colonoscopy. In the preoperative period, the etiology of intussusception (neoplasm, idiopathic, etc.) was diagnosed only in one patient (16.6%). Two patients underwent laparoscopic segmental small bowel resection, two patients underwent laparoscopic right hemicolectomy, one patient underwent laparoscopic left hemicolectomy, and one patient underwent laparoscopic anterior resection. None of the patients developed intraoperative or postoperative complication. The histopathological examination revealed malignancy in two patients (33.3%).

CONCLUSION

CT is helpful in diagnosing of adult intussusception. However, it is usually difficult to define the underlying pathology with CT. Laparoscopic approach seems to be safe and effective as open surgery, both in diagnosis and treatment of intussusception.

Pancreatic stump closure using only stapler is associated with high postoperative fistula rate after minimal invasive surgery

BACKGROUND/AIMS

Postoperative pancreatic fistula (POPF) is the most common cause of morbidity and mortality after distal pancreatectomy (DP). The aim of the present study is to determine the risk factors that can lead to POPF.

MATERIALS AND METHODS

The study was conducted between January 2008 and December 2012. A total of 96 patients who underwent DP were retrospectively analyzed.

RESULTS

Overall, 24 patients (25%) underwent laparoscopic distal pancreatectomy (LDP) and 72 patients (75%) open surgery. The overall morbidity rate was 51% (49/96). POPF (32/96, 33.3%) was the most common postoperative complication. Grade B fistula (18/32, 56.2%) was the most common fistula type according to the International Study Group on Pancreatic Fistula definition. POPF rate was significantly higher in the minimally invasive surgery group (50%, p=0.046). POPF rate was 58.6% (17/29) in patients whose pancreatic stump closure was performed with only stapler, whereas POPF rate was 3.6% (1/28) in the group where the stump was closed with stapler plus oversewing sutures. Both minimally invasive surgery (OR: 0.286, 95% CI: 0.106-0.776, p=0.014) and intraoperative blood transfusion (OR: 4.210, 95% CI: 1.155-15.354, p=0.029) were detected as independent risk factors for POPF in multi-variety analysis.

CONCLUSION

LDP is associated with a higher risk of POPF when stump closure is performed with only staplers. Intraoperative blood transfusion is another risk factor for POPF. On the other hand, oversewing sutures to the stapler line reduces the risk of POPF.

High levels of impulsivity in rats are not accompanied by sensorimotor gating deficits and locomotor hyperactivity

High levels of impulsivity have been linked to a number of psychiatric disorders, including attention-deficit/hyperactivity disorder, drug abuse and schizophrenia. Additionally, schizophrenia patients commonly show deficits in another rather preattentive form of response inhibition, called sensorimotor gating. Given that higher-order functions, such as impulse control, are protected by early and preattentive processes, disturbed gating mechanisms may hamper more complex cognitive-executive functions. In the present study, we therefore tested whether high levels of impulsivity are accompanied by impaired sensorimotor gating in rats. High (HI) and low impulsive (LI) rats were identified based on the number of premature responses in the 5-choice serial reaction time task. Here, LI rats showed higher numbers of omission errors which may suggest attentional deficits while HI rats completed significantly less trials which could indicate a decrease in motivation. However, HI and LI rats did not differ in terms of impulsive decision-making in a delay-based decision-making T-maze task, prepulse inhibition of the acoustic startle response (a measure of sensorimotor gating mechanisms) or locomotor activity levels. Overall, our data indicate that high motor impulsivity is not a suitable predictor of deficient sensorimotor gating and is further not necessarily associated with attentional deficits and/or locomotor hyperactivity in rats.

Fukushima radionuclides at air filter and rain water samples collected from Istanbul and their atmospheric removal time

Accident at Fukushima Daiichi Nuclear Power Plant (FDNPP) is one of the most serious accident in the world after Chernobyl accident. Following the continuing release of radionuclides in air after FDNPP, traces of fission products ((131)I, (134)Cs and (137)Cs) were recorded in the air filter and rain water samples collected from the ÇNAEM area at İstanbul on 4 April 2011. Airborne particle samples were collected daily in air filters and radio assayed with a high purity germanium detector. The fission products (131)I, (134)Cs and (137)Cs were measured with the maximum activity concentrations of 1.03±0.08, 0.25±0.03 and 0.23±0.03 mBq m(-3), respectively. For determination of the origin of the releases the (134)Cs/(137)Cs ratio was calculated between 1.09 and 0.85. The authors find removal times for (137)Cs of 8.13 d, (134)Cs of 7.25 d and (131)I of 6.82 d.

Keutel syndrome in a patient presenting with hearing loss

Keutel syndrome (KS) is a rare autosomal recessive disease which is mainly characterised by abnormal cartilage calcification, peripheral pulmonary artery stenosis, sensorineural and conductive hearing loss, brachytelephalangism, and midface hypoplasia. Here, we present and discuss a Keutel syndrome patient with hearing loss born to consanguineous parents (first cousins), along with all the characteristic features of KS.

Expanding CEP290 mutational spectrum in ciliopathies

Ciliopathies are an expanding group of rare conditions characterized by multiorgan involvement, that are caused by mutations in genes encoding for proteins of the primary cilium or its apparatus. Among these genes, CEP290 bears an intriguing allelic spectrum, being commonly mutated in Joubert syndrome and related disorders (JSRD), Meckel syndrome (MKS), Senior-Loken syndrome and isolated Leber congenital amaurosis (LCA). Although these conditions are recessively inherited, in a subset of patients only one CEP290 mutation could be detected. To assess whether genomic rearrangements involving the CEP290 gene could represent a possible mutational mechanism in these cases, exon dosage analysis on genomic DNA was performed in two groups of CEP290 heterozygous patients, including five JSRD/MKS cases and four LCA, respectively. In one JSRD patient, we identified a large heterozygous deletion encompassing CEP290 C-terminus that resulted in marked reduction of mRNA expression. No copy number alterations were identified in the remaining probands. The present work expands the CEP290 genotypic spectrum to include multiexon deletions. Although this mechanism does not appear to be frequent, screening for genomic rearrangements should be considered in patients in whom a single CEP290 mutated allele was identified.

Prenatal diagnosis of isolated macrodactyly

Congenital enlargement of one or several digits of the hands or feet, known as macrodactyly, is a rare malformation. True macrodactyly, characterized by overgrowth of all mesenchymal elements, must be differentiated from that due to tumorous enlargement of a single element, as in hemangioma, lymphangioma or enchondroma. Furthermore, macrodactyly may be isolated, but it can also be associated with several syndromes. Here we present a case of prenatally diagnosed isolated true macrodactyly of the second toe of the left foot at 24 weeks of gestation, and discuss the key points in its differential diagnosis and management.

Supernumerary chromosome der(22)t(11;22): Emanuel syndrome associates with novel features

Emanuel syndrome results from +der(22)t(11q23;22q11). Cleft palate, ear anomalies, heart defects, genital anomalies, hypotonia, and mental retardation are the main features of the syndrome. We report a nine-year-old boy with the t(11;22)(q23;q11) chromosome, transmitted in an unbalanced fashion from his mother, and originated in the maternal grandmother's meiosis. In addition to mental retardation, hypotonia, craniofacial anomalies, and cryptorchidism, he has novel findings such as, joint hyperextensibility, left liver lobe agenesis, left sided malposition of the gallbladder and pancreas hypoplasia. This is the first report associating these features with Emanuel syndrome.

Acute severe reversible oligohydramnios induced by indomethacin in a patient with rheumatoid arthritis: a case report and review of the literature

Although the association between oligohydramnios and indomethacin use for premature labor has been well known for many years, there have been few cases published about it. We present a case of indomethacin-induced oligohydramnios due to use in a patient for rheumatoid arthritis. A 27-year-old G2P1 woman was referred to our prenatal unit with oligohydramnios at 33 weeks of pregnancy. Ultrasonography revealed severe oligohydramnios with an amniotic fluid index of 0.9 cm. She gave a history of daily 150 mg indomethacin use for newly diagnosed rheumatoid arthritis. All possible reasons for oligohydramnios were excluded and indomethacin was discontinued. In four days the amniotic fluid was observed as normal. We concluded that the oligohydramnios caused by indomethacin occurs quickly, is dose-related and reversible. Amniotic fluid volume should be monitored while using indomethacin.

Joubert syndrome co-existing with partial Xp trisomy: review of the literature

We report a five-year-old girl who has been clinically diagnosed as Joubert syndrome. Her cytogenetic analysis showed 46,XX,der(2)add(2q37) karyotype. Cytogenetic analysis of her mother and maternal grandmother revealed a karyogram designated as 46,X,t (X;2)(p11.2;q37). The proband's derivative chromosome was further confirmed to be a translocation chromosome 2 carrying segments from chromosome X, which originated from a segregation event of the maternal grandmother's balanced translocation passed on as a balanced translocation to the proband's mother either. So far, a number of candidate genes including EN1 on 2q were analyzed for Joubert syndrome. Based on our proband's abnormal karyotype, we suggest that further mapping studies for the syndrome should also be directed towards the chromosome X segments present on the derivative chromosome 2 of our proband.

Fetal cerebellar hemorrhage in a severely growth-restricted fetus: natural history and differential diagnosis from Dandy-Walker malformation

This is a report of an intracerebellar hemorrhage in a severely growth-restricted fetus with pathological Doppler findings of the fetal and uteroplacental circulations. The diagnosis was made sonographically at 22 weeks of gestation and the natural course of the hemorrhage was followed. Interestingly, the final sonographic appearance of the posterior fossa was quite similar to that of the classic form of Dandy-Walker malformation: absence of the vermis and an enlarged fourth ventricle. However, careful sonographic examination showed that the enlargement of the fourth ventricle was actually caused by a porencephalic cystic lesion of the left cerebellar lobe. Pathological examination revealed complete absence of the vermis and cerebellar hypoplasia.

Dysmorphic face in two siblings with infantile neuroaxonal dystrophy

Infantile neuroaxonal dystrophy (INAD) is an autosomal recessive, neurodegenerative disease with onset in the first or second year of life. It has been reported that INAD shows numerous phenotype characteristics including problems associated with vision, hearing and physical coordination. It has however been very rare to see facial dysmorphism in these children. The study analyzes a girl and boy of a first cousin marriage with infantile neuroaxonal dystrophy affected at birth. At infancy, the children were examined in the Cerrahpaşa Medical Faculty Genetic Research Center, Istanbul. They had typical INAD features such as the lack of head control, vision, speech, sitting, and walking which are also seen in children with other congenital abnormalities. These children showed remarkable dysmorphism in the face which included prominent forehead, strabismus, small nose, fish mouth (boy), micrognathia, and large and low-settled ears. The presence of these facial features makes the patients appear unique and diagnosis more accurate. While these features are commonly seen diagnosis may be difficult at its onset. Until now this appearence has not been reported in INAD patients. In conclusion, in the first few months of life without any clinical or neurological signs, the physician should also consider diagnosing the disease of the infant as INAD.

Trisomy 9p syndrome in two brothers: with new clinical findings and review of the literature

We report an eleven years old boy and his fourteen years old brother who both have trisomy 9p syndrome. Their cytogenetic analysis using GTL-banding showed 46,XY,der(22)add(22)(p11) karyotype. Cytogenetic analysis of their mother and sister revealed a karyogram designated as 46,XX,t(9;22) (9pter-->9p12::22p11-->22qter). With the help of FISH technique, the derivative chromosome in the proband was further confirmed to be a translocation chromosome 22 carrying the aforementioned segments from chromosome 9 which originated from a segregation event of a mother's balanced translocation. Regarding clinical aspects of our cases, both showed similar findings of 9p trisomy syndrome but low frontal hairline, circular placement of the hair around the face and scarce, inverted eyebrows, findings not previously mentioned in the literature. We conclude that these new clinical findings could be used in the clinical diagnosis of the 9p trisomy syndrome along with the other well-documented symptoms.

Changes in the antioxidant system in epileptic children receiving antiepileptic drugs: two-year prospective studies

The aim of this study was to measure changes in the antioxidant systems of epileptic children who had been receiving either valproate or carbamazepine monotherapy for 2 years. For this purpose, levels of erythrocyte glutathione, glutathione peroxidase, superoxide dismutase, and serum lipid peroxidation in 25 healthy children and 27 children who had previously been diagnosed as having epilepsy but who had not, prior to the study, received antiepileptic drugs were tested. Of the 27 epileptic children, 14 were given valproate, and the remaining 13 were given carbamazepine; these tests were repeated in the 13th and 24th months of treatment. The results showed that, during valproate therapy, the lipid peroxidation levels of the epileptic children increased and the glutathione peroxidase levels decreased in comparison with those levels recorded in the control and pretreatment groups. In addition, the superoxide dismutase levels were found to be increased during the first year of valproate therapy when compared with those of the pretreatment group. However, during carbamazepine therapy, lipid peroxidation levels increased when compared with the control group only, not the pretreatment group. Furthermore, the results showed that during the second year of treatment, the superoxide dismutase levels of the children receiving carbamazapine monotherapy were found to be higher than those of both the control and pretreatment groups. From these results, it can be concluded that the antioxidant systems of the children who had been receiving valproate therapy during the 2 years were more significantly affected than those of the children who had been receiving carbamazepine.

Infantile-onset megalencephalic leucoencephalopathy in two siblings

Infantile-onset megalencephalic leucoencephalopathy (IML) is a recently recognized autosomal recessive white matter disorder. Unlike other megalencephalic leucoencephalopathies, in patients with IML a mild clinical course, a slowly progressive delay in motor development and mild mental deterioration are typical. We report on two affected siblings who have typical clinical and radiological findings of IML. Cranial magnetic resonance imaging showed involvement of the capsula externa, extrema and interna, nucleus dentatus, crus cerebri, periventricular and subcortical white matter. In addition, bilateral cystic changes were determined predominantly in the temporal lobes. There were no clear biochemical or metabolic disturbances. In the present paper, we discuss the clinical and neuroimaging findings of IML.

Erythrocyte glutathione, glutathione peroxidase, superoxide dismutase and serum lipid peroxidation in epileptic children with valproate and carbamazepine monotherapy

This prospective study was carried out to determine changes in the antioxidant system in epileptic children receiving long term antiepileptic drugs (AEDs). Levels of erythrocyte glutathione (GSH), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and serum lipid peroxidation were determined in 25 healthy children and 30 epileptic children who had not yet received AEDs. Sixteen patients were treated with valproic acid (VPA) and 14 with carbamazepine (CBZ); 13 months later these parameters were retested. The results showed that SOD and lipid peroxidation levels were increased but the GSH-Px levels were decreased in epileptic children on VPA therapy compared with the control group and the results before treatment. No significant differences of these parameters were found in epileptic children on CBZ therapy compared with the control group and the results before treatment, except that lipid peroxidation level was slightly higher in epileptic patients before treatment. We conclude that antioxidant systems in epileptic children on CBZ therapy are better regulated in comparison with epileptic children on VPA therapy.

Siblings with cystic leukoencephalopathy and megalencephaly

Cystic leukoencephalopathy with megalencephaly is a newly described entity with mild clinical involvement. Patients suffer from developmental problems and seizures in childhood. Progression is gradual into adulthood. Typical magnetic resonance imaging findings include subcortical cysts and diffuse leukoencephalopathy. The etiology is unknown with possibly autosomal-recessive inheritance. We present two pairs of siblings with this disease and emphasize the characteristic and variable patterns even within the same family.

A variant of Cenani-Lenz type syndactyly

Cenani-Lenz syndrome is a form of complete syndactyly resembling the spoon hand in Apert syndrome. It is often associated with disorganization of phalanges, the fusion of metacarpals and mesomelic shortness of the arm. We describe an additional case of Cenani-Lenz type of syndactylism in a 16 month-old girl who also has rib and vertebral abnormalities and mixed type hearing loss, that have not been seen before in a single patient.

The effects of carbamazepine and valproic acid on the erythrocyte glutathione, glutathione peroxidase, superoxide dismutase and serum lipid peroxidation in epileptic children

Some epileptic drugs may change antioxidant enzyme activities in humans and experimental animals. Recent studies suggest that membrane lipid peroxidation may be causally involved in some forms of epilepsy, and the differences are reported in free radical scavenging enzyme levels. GSHpX, SOD, GSH are important parameters of antioxidant defence mechanisms. This study was undertaken to evaluate the effects of valproic acid and carbamazepine (CBZ) therapy on erythrocyte glutathione (GSH), glutathione peroxidase (GSHpX), superoxide dismutase (SOD) and lipid peroxidation. During the treatment with VPA or CBZ, the erythrocyte GSHpX and GSH levels of epileptic children were significantly changed as compared to those of health control subjects. The mean levels of serum lipid peroxidation and erythrocyte superoxide dismutase were not statistically different from controls. The methods used for investigation of glutathione peroxidase, superoxide dismutase, glutathione and serum lipid peroxidation were all based on spectrophotometric measurement.

Two female siblings with a previously unreported MCA/MR syndrome: pre- and postnatal growth retardation, iris colobomata, spasticity, facial dysmorphism and dilated ventricles

We report two siblings from non consanguineous parents with a similar MCA/MR syndrome: Pre- and postnatal growth retardation, microcephaly, mental retardation, iris colobomata, facial dysmorphism, spasticity, dilated ventricles and abnormal immunoglobulin levels. Review of published reports and the use of the London Dysmorphology Database suggests that these siblings may present a new syndrome.

Neuroimaging findings of four patients with Sandhoff disease

Sandhoff disease is a severe form of GM2 gangliosidosis that is caused by the deficiency of both hexosaminidase A and B. Startle reaction, hypotonia, psychomotor retardation, and blindness are the main clinical features. Presented are computed tomography and magnetic resonance imaging findings of four patients with Sandhoff disease diagnosed by enzymatic analyses. Bilateral homogeneous thalamic hyperdensity was evident on computed tomography. Magnetic resonance imaging scans revealed mild cortical atrophy, a thin corpus callosum, and abnormal signal intensities in the caudate nucleus, globus pallidum, putamen, cerebellum, and brainstem. No correlation was evident between the severity of the central nervous system imaging findings and the clinical pictures. In this article the neuroimaging findings of four patients with Sandhoff disease are discussed.

Preparation of spray-dried microspheres of indomethacin and examination of the effects of coating on dissolution rates

In this study, microspheres were prepared by the spray drying technique using suspensions of indomethacin (IM) as active substance and coated by three different polymers in order to increase the dissolution rate of IM. Water solutions (0.1, 0.2 and 0.5%) of hydroxypropylmethyl cellulose (HPMC), polyvinyl alcohol (PVA) and hydroxypropyl cellulose (HPC) were used as coating materials. Polyethylene glycol 400 (PEG 400) was added to all formulations as plasticizer. Changes of particles size and surface characteristics of the coated products were examined using optical microscopy and scanning electron microscopy (SEM), respectively. The effects of coatings on the dissolution rates of IM were examined using USP XXIII Method II in water and phosphate buffer pH 7.4. It was observed that coating the IM particles with HPMC, PVA and HPC polymers using the Spray-Drying Technique increased the dissolution rate of IM significantly.

N-acetyl-beta-glucosaminidase and beta-galactosidase activity in children receiving antiepileptic drugs

To evaluate renal tubular function in children receiving antiepileptic drugs the urinary activity of two lysosomal enzymes, N-acetyl-beta-glucosaminidase and beta-galactosidase, were measured. The enzyme levels were determined before the administration of antiepileptic drugs and 8 months after. Fourteen epileptic children received valproate, and 17 received carbamazepine. The urinary activity of these enzymes in 25 healthy control patients also was examined. Increased N-acetyl-beta-glucosaminidase activity was found in 50% of patients taking valproate and in 17.6% of patients taking carbamazepine. Increased beta-galactosidase activity was found in 28.5% of patients taking valproate and 11.7% of patients taking carbamazepine compared with the results before treatment. On the basis of these results, it is suggested that patients taking antiepileptic drugs, especially valproate, may demonstrate minor signs of tubular dysfunction. In those patients who use these drugs at increased dosage levels or for long periods, the possibility of tubular dysfunction may be increased, and these dysfunctions may manifest in clinical symptoms.

A family presenting Goltz syndrome (focal dermal hypoplasia) in three generations

In this report we present three affected females of the same family in three generations. The cases have features of focal dermal hypoplasia (Goltz syndrome). One of the three affected females is the index case and the others are her mother and her grandmother. We performed skin biopsies on them. According to histopathological examinations skin lesions were compatible with Goltz syndrome. These cases exhibited focal dermal hypoplasia (FDH) manifestations including skin, dental and skeletal abnormalities. The affected females were seen in three generations of the same family which pointed to its X-linked dominance.

The extent of leprosy-related disabilities in Istanbul Leprosy Hospital, Turkey

This study was carried out between January and December 1992 at the Istanbul Leprosy Hospital. Seven hundred and eleven leprosy patients were evaluated according to their age, gender and type of disease and disability according to the WHO disability grading system (1980). There were 527 males (74.2%) and 184 females (25.8%) in the group. The average age was 50.0 +/- 13.5 years and the average duration of disease was 25.9 +/- 13.2 years. Six hundred and seventy-eight patients (95.4%) were in borderline (BL) and lepromatous (LL) leprosy. The extent of disabilities was very high in 711 leprosy patients. It was found that 539 of the patients (75.8%) had eye disabilities, 511 of them (71.8%) had hand disabilities, 521 of them (73.3%) had foot disabilities. The most frequent eye, hand and foot disabilities were a decrease of vision (52.7), acute or chronic iridocyclitis (48.8%), slightly-marked corneal sensory loss (43.2%), mobile claw hand (33.3%), palmar insensitivity (16.3%), plantar ulcer (37.2%) and plantar insensitivity (19.8%). Eye deformities were the most common of the three affected areas in this study.

Effect of valproate and carbamazepine on visual evoked potentials in epileptic children

The effects of carbamazepine (CBZ) and sodium valproate (SV) monotherapy on visual evoked potentials (VEP) were studied in 18 epileptic children receiving CBZ and nine epileptic children receiving SV. Pattern reversal VEP were determined before the administration of antiepileptic drugs (AED) and 1 year later during which time the patients had received AED. The VEP amplitude showed no consistent changes after 1 year of CBZ and SV therapy, but VEP P-100 latencies were significantly prolonged after 1 year of CBZ therapy. We conclude that CBZ causes a slowing down of central impulse conduction and that VEP is useful to evaluate the effects of AED within the central nervous system.

Tetra-amelia, lung hypo-/aplasia, cleft lip-palate, and heart defect: a new syndrome?

We report on a family with two sons affected with tetra-amelia, cleft lip-palate, bilateral agenesis of lungs, and heart defects. These two cases support the previous suggestions that this complex entity may indeed represent a new syndrome. However, the mode of inheritance is still not clarified.

Influence of long-term carbamazepine treatment on thyroid function

We have studied the effects of carbamazepine on thyroid function in sixteen recently diagnosed epileptic children and thirteen epileptic children receiving long-term carbamazepine therapy and compared these findings with the thyroid function of thirteen healthy control subjects. Thyrotropin (TSH), triiodothyronine (T3), thyroxine (T4), free triiodothyronine (FT3) and free thyroxine (FT4) serum levels were determined in both recently diagnosed but as yet untreated epileptic children and normal controls. These hormone levels were determined again after 2 months of treatment and 12 months of treatment in epileptic children. No statistically significant difference was found in the endocrine parameters of untreated epileptic children and the normal control group. After both 2 months and 12 months of carbamazepine therapy, serum levels of T4, FT4 and FT3 were found to be low, but the serum T3 concentration was unaffected. Baseline TSH levels were not changed during carbamazepine therapy either. Serum TSH levels increased rapidly after thyrotropin-releasing hormone stimulation in both the before and 12 months after carbamazepine treatment groups, but the response was higher in the 12 months treatment group. The findings of the present study suggest that accelerated hormone metabolism is responsible for hormonal changes found in patients treated with carbamazepine. Carbamazepine also had effects on the function of the hypothalamo-pituitary axis.

Serum thyroid hormones and pituitary response to thyrotropin-releasing hormone in epileptic children receiving anti-epileptic medication

Thyroid hormones and pituitary function were assessed in 49 children with epilepsy who were receiving either a single medication of carbamazepine, phenobarbital and valproate or a combination of carbamazepine with phenobarbital or valproate. All therapeutic regimens except valproate monotherapy were associated with low levels of circulating thyroxine, free tri-iodothyronine and free thyroxine. Carbamazepine with valproate was associated with the lowest serum concentration of thyroid hormones. It seems probable that accelerated hormone metabolism is responsible for these hormonal changes. However, all drug regimens also had effects on the function of the hypothalamic pituitary axis. Because of these findings, thyroid hormones should be checked frequently during anti-epileptic drug treatment, although clinical hypothyroidism was not seen in our patients.

Women and leprosy in Turkey

Women in Turkey have many social, cultural and economical problems. Women with leprosy have problems in common with other women as well as those related to physical and social consequences of leprosy. There are 2,414 patients with leprosy in Turkey, registered to Istanbul Leprosy Hospital and 829 of them are females. The mean age and duration of disease of our female leprosy patients are high. Most women with leprosy were born in eastern part of Turkey where prevalence of leprosy is higher and most have moved to western regions. The proportion of women who have some kind of social security is very low. Their economic status is also not good and 79% of patients had stigma about their disease. Three fourths of these cases have been hospitalized some time, for different reasons. Most of them (97.2%) have inactive disease at present. Disability degrees of patients are high. Patients with disability degrees over one constitute 54% of total for eyes, 55% for hands and 51% for feet. High percentage of multibacillary form and long duration of disease, delayed diagnosis, insufficient self-care of patients due to low socio-economic and cultural status and failure of health personnel to control patients periodically may be among the reasons for such high ratios of moderate and severe disabilities. In the light of the data obtained in our study, some measures to alleviate the problems of patients resulting from their socio-economic, cultural and social status have been suggested.
