Risk factors for brachial plexus injury and permanent sequelae due to shoulder dystocia

AIM

The primary aim of this study was to determine the risk factors for the occurrence of brachial plexus injury in cases of shoulder dystocia. Secondly, it was aimed to determine the factors affecting the occurrence of permanent sequelae in cases with brachial plexus injury.

SUBJECTS AND METHODS

ICD-10 codes were scanned from the records of patients who gave birth between 2012 and 2018, and the records of patients with brachial plexus injury and shoulder dystocia were reached. Shoulder dystocia cases with brachial plexus damage were accepted as the study group, and shoulder dystocia cases without brachial plexus damage were considered the control group. Shoulder dystocia patients with brachial plexus injury and without injury were compared for 2-year orthopedics clinic follow-up reports, surgical intervention, permanent sequelae status as well as birth data, maternal characteristics, and maneuvers applied to the management of shoulder dystocia.

RESULTS

Five hundred sixty births with shoulder dystocia were detected. Brachial plexus injury was observed in 88 of them, and permanent sequelae were detected in 12 of these patients. Maneuvers other than McRobert's (advanced maneuvers) were used more and clavicle fracture was seen more in the group with plexus injury (P < 0.05, P < 0.05, respectively). Logistic regression analysis was performed to determine the risk factors of brachial plexus injury. Brachial plexus injury was observed 4.746 times more in infants who were delivered with advanced maneuvers and 3.58 times more in infants with clavicle fractures at birth.

CONCLUSION

In patients with shoulder dystocia, the risk of brachial plexus injury increased in deliveries in which advanced maneuvers were used and clavicle fracture occurred.

Contact sensitization in children with atopic dermatitis

BACKGROUND

Atopic dermatitis is a common illness in childhood. Children with atopic dermatitis are prone to develop cutaneous sensitization due to skin barrier dysfunction.

AIM

The aim of this study was to evaluate the frequency of cutaneous sensitizations in patients with atopic dermatitis and to identify the most frequent causative allergens.

STUDY DESIGN

The study group consisted of 112 children with atopic dermatitis, aged 1-18 years (median 88.5 months) and 39 healthy controls, aged 1-8 years (median 88.48 months).

METHODS

The diagnosis of atopic dermatitis was established by modified Hanifin and Rajka criteria; severity of the disease was assessed by scoring of atopic dermatitis. Serum blood eosinophil count, total IgE and skin prick tests for common aeroallergens and food allergens were performed. Patch tests with cosmetic series and European standard patch test series (Stallegenes© Ltd, Paris, France) were applied.

RESULTS

Of the children with atopic dermatitis, 17% (n=19) were sensitized to either cosmetic or standard series or both of them; no children in the control group had a positive patch test (p=0.001). Atopy and severity of atopic dermatitis was not a significant risk factor for cutaneous sensitization. The most common allergens were Nickel sulphate and Methychloroisothiazinolone (4.5% and 4.5%) in the European standard patch test and cocamidoproplybetaine (12.5%) in the cosmetic series patch test.

CONCLUSION

Cutaneous sensitization can develop in children with atopic dermatitis, therefore allergic contact dermatitis should be kept in mind.

Evaluation of pancreatic exocrine functions in rheumatoid arthritis

BACKGROUND

Rheumatoid arthritis (RA) is one of the most common chronic inflammatory diseases. It mainly involves the joints and also affects directly or indirectly nearly all organ systems. The question whether RA causes exocrine pancreatic disfunction remains unclear. The purpose of this study is to evaluate whether or not RA contributes to pancreatic exocrine insufficiency. This was done by ruling out seconder Sjögren's syndrome (SjS) by using Schirmer's test.

METHODS

A total of 60 patients (20 RA, 20 RA + SjS and 20 SjS) and 20 healthy volunteers were included in the study. Patients with RA who had not undergonethe Schirmer's test in the last 6 months and all healthy volunteers included in the study underwent the Schirmer's test at an outpatient clinic. Random fecal samples were taken from all participants and fecal pancreatic elastase was measured to evaluate pancreatic exocrine functions.

RESULTS

In the study, a statistically significant difference was found between the control group,SjS and RA+SjS groups. But there was no significant difference between the control group and RA group. In RA group, fecal elastase levels were statistically significantly higher compared to the SjS group. But there was no significant difference between RA+SjS and SjS groups.

CONCLUSION

Fecal elastase significantly decreased in SjS compared to the normal population while pancreatic exocrine functions are considered to be impaired in SjS. There are also impaired pancreatic exocrine functions in the secondary SjS associated with RA. Consequently, pancreatic exocrine dysfunction, which can be seen in patients with RA, may be thought to be caused by secondary SjS associated with RA (Tab. 6, Fig. 1, Ref. 19).

HE4: really a novel biomarker for ovarian cancer?

Ovarian cancer forms 4% of all cancers and approximately 23% of all gynecological cancers in women and is responsible for the 47% of deaths related to cancers of the genital tract of women. Tumor markers are the biochemical substances which can be detected in the presence of tumors. Generally they are either the products of tumoral tissues or secreted from the normal cells which are in the inter- action with tumoral ones. The present authors attempted to determine the efficacy of the tumor marker CA- 125 and HE4 to differentiate the malign cases from the benign adnexal masses. A total of 76 patients with the appropriate criteria were included in the study. They were divided into three groups; healthy control group (n=3 1), ones with benign masses (n=23), and ones with malign ovarian masses (n=22). In the study, when the cut-off values were accepted as 55I U/ml for CA-125 and 150 pM for HE4 in differentiation of benign and malign groups, the sensitivity was found as 59.09%, specificity 91.3%, PPV 86.67% and NPV 70% LR = +6.8. This combination gives one false positive result to every five positive cases which were detected as high. With the combination of CA-125 and HE4, the value of sensitivity was found decreased as expected, although the value of the specificity increased.

Endoanal ultrasonographic evaluation of an unhealed anal fissure after the lateral internal sphincterotomy

OBJECTIVES

The aim of this study was to evaluate the outcomes of the lateral internal sphincterotomy in patients who had unhealed anal fissures using the endoanal ultrasonography.

BACKGROUND

Lateral internal sphincterotomy is an effective method in treatment of chronic anal fissures, but it is associated with 1 to 5 % unhealing and recurrence rates. Endoanal ultrasonography can be used to evaluate the sphincterotomy and the efficiency of the treatment.

METHODS

Totally, 40 patients with unhealed anal fissures after the lateral internal sphincterotomy were enrolled consecutively. The fissures were diagnosed by proctologic examination in every patient. The results of sphincterotomy were evaluated by the endoanal ultrasonography.

RESULTS

There were 23 men and 17 women with the median age 29.7 years (range, 20-44 years). Using the endoanal ultrasonography, an incomplete internal sphincterotomy was detected in 26 of patients. In 12 patients, while the internal sphincter was completely intact, a superficial (subcutaneous) external anal sphincterotomy was found. In two patients, although the internal sphincterotomy was observed to be sufficient, a localized abscess formation of less than 1 cm was detected at the anal crypts level.

CONCLUSION

The use of endoanal ultrasonography in patients with unhealed or recurrent anal fissure is a beneficial diagnostic method in assessing the situations of sphincters after the lateral internal sphincterotomy. Although the lateral internal sphincterotomy is a successful surgical treatment and can be performed easily as an outpatient procedure, it should be performed with the correct and rigorously surgical technique (Tab. 2, Fig. 3, Ref. 31).

Spontaneous cholecystocutaneous fistula as a rare complication of gallstones

Spontaneous perforation of gallbladder as a complication of biliary stones may lead to a cholecystocutaneous abscess or fistula. The pathophysiology of this condition has been associated with increased pressure in the gallbladder, secondary to biliary obstruction. Ultrasonography and Computed Tomography (CT) can be used for diagnosis of cholecystocutaneous abscess or fistula. The treatment of fistula requires adequate drainage, antibiotics, followed by elective cholecystectomy with excision of the fistula. We report a case of spontaneous cholecystocutaneous fistula in an 89-year-old female patient who presented with obstructive jaundice and subcutaneous abscess in the right subcostal area. Abdominal CT scan showed gallstones and communication between the abscess and the gallbladder. First abdominal wall abscess was drained externally then cholecystectomy and exploration of common bile duct was performed (Fig. 3, Ref. 8).

Prognostic value of oncoprotein expressions in thyroid papillary carcinoma

The aim of this study was to evaluate the expressions of oncoproteins and to correlate the results with clinicopathologic parameters in papillary thyroid carcinoma (PTC). Papillary thyroid cancer (PTC) is the most common form and accounts for about 80% of all thyroid cancers. Although PTC generally has a good prognosis, some patients suffer from local recurrence and/or distant metastasis. Oncogenes have reported to be related not only in carcinogenesis but also in tumor prognosis, tumor type, differentiation and site of tumor in epithelial malignant tumors such as thyroid, breast, ovarian, and stomach cancer. This study was planned retrospectively and was performed in 87 patients (47 PTC, 40 benign lesions). The data of clinicopathologic parameters and tissue samples were collected from the archives. Sections stained with H&E were evaluated for each case and after confirming the diagnosis of PTC, oncoprotein expressions were determined by immunohistochemical analysis. The differences of oncoprotein expressions in PTC compared with control group were statistically significant. Cyclin D1 and p53 expressions were significantly increased in PTC. The expressions of bcl-2 and c-erbB-2 in PTC were found as increased, but the correlation between these proteins and poor prognostic parameters were not significant. We suggest that increased expressions of cyclin D1 and p53 could be used as prognostic factors in patients with PTC.

Constipation as a defecation disorders: what do we expect from the physiologic tests?

BACKGROUND

Constipation is often associated with some clinical signs as hard stool, incomplete defecation, chronic straining, and abdominal pain and long stays in bathroom. Some diagnostic uncertainties came from functional and structural variations of the anorectum and the assessment from few imaging procedures, which were thought as the best but could not always give the expected result. Then physiologic tests were required to be used. The aim was to study which physiologic test correlated to the clinical symptoms, was valuable and have to be performed in the patients with chronic constipation in this series.

METHODS

One hundred twenty-seven patients (56.3 % females; mean age, 56.7) with chronic constipation according to the Rome II criteria were initially treated by dietary change and increased physical activation. The unresponsive (80) patients were instructed to be evaluated by the physiologic tests (anal manometry, defecography, colonic transit time-CTT) and clinical symptoms. The assessments from physiologic tests, which were originated from 4 distinctive categories, were investigated by factor analysis. ROC curve analysis was used to take involved assessments, which had a big impact on the constipation status.

RESULTS

80 patients, mostly female (89 %), had experienced several symptoms in 11.9 years. The CCT, scoring system, evacuation problem, hard stool, habitual laxative use and digital assist for defecation were significantly different in 17 factors originated from different categories. We analyzed the extracted factor, which had an important effect on the constipation and consequently considered the necessary physiologic test and other related symptoms.

CONCLUSIONS

Scoring system, CTT, anal manometry and other physiologic tests are important to establish a true diagnosis of the etiology of the constipation. However, defecography and clinical symptoms are the factors, which has a great impact on the diagnosis of constipation (Tab. 7, Ref. 25).

Accuracy and safety of percutaneous US-guided needle biopsies in liver metastasis and hemangiomas

AIM

The aim of this study was to compare small size aspiration and large size cutting needles on the diagnostic yield in the biopsies of liver and especially to investigate the reliability on percutaneous biopsy of liver hemangiomas.

METHODS

Nine hundred fifty patients with percutaneous ultrasonography-guided liver biopsies were evaluated retrospectively. This study enrolled 841 patients biopsied with either large size cutting needle (Tru-cut 14G-18G) or small size aspiration needle (WestCott 20G). Further evaluation was performed in 312 patients with metastasis and 48 patients with hemangiomas.

RESULTS

Diagnostic yield was higher in the large size cutting needle group (96.8%, 150/155) than in the small size aspiration needle group (84.1%, 132/157) in liver metastasis (P<0.001). There was no significant difference among diagnostic accuracies of Tru-cut 14G, 16G, and 18 G needles in metastasis (P=0.255). Accuracy rate was 77.9% (208/267) in benign and 89.5% (514/574) in malignant diseases. Sensitivity, specificity, and accuracy were 81.2% (514/633), 100% (208/208), and 85.8% (722/841), respectively. Only two major complications were found (0.16%) with small needles.

CONCLUSION

The authors suggest the use of large size cutting needles, because they provide more accurate diagnosis, and should be used in liver metastasis instead of small aspiration needles, if there is no on-site pathologist at aspiration biopsies or a more specific diagnosis is required. Among them, 18G cutting needle should be chosen. All the needles, including the large cutting type, were found safe in the biopsies of liver hemangiomas.

The role of HLA-DRB1 shared epitope alleles in predicting short-term response to leflunomide in rheumatoid arthritis

OBJECTIVES

To investigate the role of shared epitope (SE) alleles in the short-term clinical response to leflunomide for the treatment of active RA.

METHODS

In an open-label, multi-centre study of 16-weeks duration, 93 patients (82% female) fulfilling ARA 1987 RA criteria were treated with leflunomide (100 mg loading dose for 3 days, then 20 mg/day as the maintenance dose). The primary efficacy criterion was the response status according to the European League Against Rheumatism (EULAR) response criteria using Disease Activity Score-28 (DAS28) activity measure. SE determinations have been undertaken by polymerase chain reaction and sequence-specific oligonucleotide genotyping methods.

RESULTS

The mean (s.d.) Disease Activity Score-28 (DAS28) was 5.1 (1.3) before the treatment, which was significantly decreased after 16 weeks [3.0 (1.1), P < 0.001]. According to the EULAR response criteria, 55 patients (59.1%) were classified as good responders. SE was positive in 51 (54.8%) of the patients, with 13 (13.9%) having SE homozygosity or carrying any two SE alleles. Among SE-positive patients, 68.6% (35/51) were good responders, compared with 47.6% (20/42) in SE negatives (P = 0.04). No difference was present according to SE hetero- or homozygosity (68.4 vs 69.2%). RF was also present significantly more frequently in the SE-positive group compared with negatives (78.4 vs 57.1%, P = 0.03). However, no significant difference was observed in the prevalence of RF positivity in patients with a good clinical response (72.7 vs 63.2%, P = 0.32).

CONCLUSIONS

The results suggest that HLA-DRB1 SE presence may favourably affect the outcome of leflunomide monotherapy in an unselected group of RA patients with an active disease and naive to leflunomide.

Ganglioglioma with lytic skull lesions: A case report

Gangliogliomas represent only 0.4% of central nervous system neoplasms and 1.3% of brain tumors. They are benign neoplasms with low morbidity and mortality and the patients usually present with seizures, but there has been no adult ganglioglioma with lytic skull lesion. A 49-year-old right handed woman suffering from generalized epileptic seizures was admitted to our hospital. She had also left hemiparesis with 4/5 motor strength. Magnetic resonance imaging and immunohistochemical studies revealed WHO Grade II ganglioglioma. Skull X-ray showed the lytic skull lesions. We have to consider gangliogliomas in the differential diagnosis of lytic skull lesions.

Primary spinal cord oligodendroglioma. Case illustration

Spinal cord oligodendrogliomas are rare pathologies of the spinal cord, and their location at conus and/or filum terminale is even rarer. There are only 7 spinal cord oligodendrogliomas reported in the literature. Our case is the eighth spinal cord oligodendrogliomas at this location.

Spontaneous regression of cervical disc herniations

The spontaneous regression of cervical disc herniations is a rare occurrence. Six herniated cervical discs that had regressed spontaneously are presented. All radiological disc regressions correlated well with clinical improvements. We want to underscore the potential for regression that should be considered in the evaluation and management of any patient with a herniated cervical disc.

Pott's puffy tumor of the vertex years after trauma in a diabetic patient: case report

Pott's puffy tumor is a rare clinical entity characterized by subperiosteal abscess associated with osteomyelitis. It is usually seen as a complication of frontal sinusitis or trauma. This is the unique report of a Pott's puffy tumor located over the vertex of a type 1 diabetic patient with an unusual latency of 14 years following injury. A 27-year old man presented with pain and a soft swelling on his vertex. Magnetic resonance imaging demonstrated subperiosteal abscess in the vertex region associated with dural thickening and perisinusal irregularities of epidural space. Further history revealed that he had a trauma to the same location when he was 13 years old. Considering possible complications due to proximity of the lesion to the sagittal sinus, we retrained from aggressive surgical interventions. We treated our patient with a simple surgical abscess drainage followed by prolonged use of antibiotics and achieved complete therapy. The cellular and humoral elements of the immune system may be disrupted in diabetic patients resulting in such atypical courses and complications of infections. We want to emphasize both importance of the prompt diagnosis of Pott's puffy tumor as intracranial invasion may cause severe neurologic problems, and importance of a surgical intervention tailored for the individual lesion.

Surgical management of chronic total occlusion of abdominal aorta

AIM

The surgical management of the totally occluded abdominal aorta is highly complex and possible complications are more likely to be seen. We reviewed our experience to make a base for future endoluminal procedures.

METHODS

Seventy-one patients with totally occluded abdominal aorta were operated between 1985 and 1998 in a main referral hospital of the social security organization and the results of vascular interventions were evaluated retrospectively. Juxtarenal aortic occlusion was seen in 52% of these patients. All the patients were operated using the transperitoneal approach and adequate dissection to control renal arteries. Limited thrombectomy through infrarenal aortotomy without transecting the aorta was done and continued with standard aortic graft insertion except for 1 patient with porcelain aorta.

RESULTS

Follow-up was 76.9+/-41.9 (SD) months. Fourteen patients had concurrent femoro-distal bypass and 2 patients had concurrent renal bypass. Perioperative mortality was 5.6% and 26.5% of patients needed a second intervention during follow-up. Five-, 10- and 13-year survival and freedom from secondary operation was as follows: 84%, 56% and 44%, 81%, 54% and 42%. Cumulative primary and secondary graft patencies at 5- and 10-years were 68%, 63% and 92%, 92%, respectively.

CONCLUSIONS

Surgical intervention is beneficial for patients with totally occluded aorta even if ischemic complaints are relatively mild and stable. Acceptable mortality rates and long-term results form a basis for future endovascular interventions.

Valve repair for rheumatic mitral disease

BACKGROUND AND AIM OF STUDY

Mitral valve repair is the standard reparative technique for degenerative mitral disease, but results of valve repair in rheumatic disease are also encouraging. The outcomes after mitral valve repair for rheumatic disease at young age was evaluated for suitability of repair.

METHODS

A total of 319 patients (246 females, 73 males; mean age 31.3+/-0.5 years) underwent mitral valve repair for rheumatic mitral disease at the authors' institution between 1991 and 1998. Mean follow up was 51.9+/-1.2 months (range: 9-98 months), and was 88.7% complete.

RESULTS

Preoperatively, 47.6% of patients were in NYHA classes III and IV. Mitral stenosis was present in 87.5%, insufficiency in 5.3%, and stenosis/insufficiency in 7.2%. Concomitant procedures were performed in 32% of patients who had associated cardiac lesions. The intraoperative mortality, reoperation and reoperation mortality rates were 0.9%, 6.7% and 0%, respectively. During follow up there were 10 late deaths (3.5%), six of which were cardiac disease-related (2.1%). Postoperatively, 98% of patients were in NYHA classes I and II.

CONCLUSION

Valve repair in mitral disease is a standard technique, with low mortality, complication and reoperation rates, and good cardiac function and late survival. This approach is equally applicable to rheumatic mitral valve repair; hence, rheumatic mitral valves should also be repaired.

Reoperation results of arterial involvement in Behçet's disease

OBJECTIVES

to retrospectively evaluate the role of vascular interventions in Behçet's disease with arterial involvement. So far, little information is available on the surgical approach for arterial involvement in Behçet's disease.

MATERIAL AND METHODS

between February 1989 and August 1997, among 178 patients with Behçet's disease referred to our clinic, vascular involvement was established in total of 67 patients (38%) which consisted of 59 venous (33%) and 12 (7%) arterial involvements requiring urgent surgical intervention. Primary arterial lesions were occlusive in one patient, aneurysm formation in nine or both in four.

RESULTS

twelve primary operations and 12 reoperations were performed. The reasons for reoperations were anastomotic aneurysms, graft occlusion, occlusion of native vessel, graft infection, bleeding from anastomosis and aortoenteric fistula. First reoperation was performed after a mean period of 6.4 months (1-15 months). Postoperative follow-up was 12-60 months (mean 36 months) and three patients died during follow-up.

CONCLUSIONS

the surgical results were not satisfactory because of progressive graft thrombosis and formation of new aneurysms at the anastomosis. Aggressive medical treatment should be combined when major vessel involvement occurs. All types of arterial punctures for angiography or blood gases should be minimised because of the risk of new aneurysm formation. Surgical intervention is indicated only in patients with a growing aneurysm, acute rupture or severe ischaemia.

Specificity and structure of murine monoclonal antibodies against GM1 ganglioside

Anti-GM1 antibodies have been implicated in the pathogenesis of several neurological diseases, but the role of these antibodies is still controversial. An animal model could provide insight into the mechanisms of these human disorders, but obtaining specific anti-GM1 monoclonal antibodies (mAbs) has been extremely difficult because of the weak immunogenicity of GM1 ganglioside. Four murine mAbs against GM1 were elicited by immunization of mice with lyso GM1 coupled to BSA and GM1 glycolipid. All four IgM,k mAbs bound strongly to GM1, three antibodies (125, 360 and 494) also bound very weakly to asialo GM1 (GA1) and one (156) bound weakly to GD1b. Three antibodies (125, 360 and 494) were encoded by the same VH and V kappa genes. The VH gene exhibited 97% homology to VHOX1, a member of the VHQ52N gene family, the D segment was probably derived from DQ52 and JH was identical to JH2. The V kappa gene was approximately 99% homologous to V kappa RF and J kappa was germline J kappa 2. The VH gene of mAb 156 exhibited 98% homology to VH205.12, of the VHJ558 gene family, the D segment was derived from DFL16.1, and JH was germline JH2. The V kappa and J kappa genes of mAb were identical to V kappa 8 and J kappa 1, respectively. The genes encoding these anti-GM1 antibodies were close to germline sequences and have been used to encode other antibodies. This suggests that the unresponsiveness of mice to immunization is probably due to inactivation of self-reactive B cells. These rare anti-GM1 mAbs will be valuable reagents for studies of the pathogenesis of autoimmune neuropathy in animals, and also for analyzing the tissue distribution and functions of GM1.

Thromboangiitis obliterans (Buerger's disease) in women (a reevaluation)

Thromboangiitis obliterans (TAO) is an occlusive vascular disease traditionally known to be almost exclusive to young male smokers. The disease was considered to be extremely rare in women, seen only as isolated, novel case reports in the literature. In the past decade, however, a dramatic increase in the incidence of female TAO has been observed. In this paper the authors report 7 cases of clinically and angiographically verified female TAO. The world literature in regard to the diagnostic criteria, changing incidence, and etiology is reviewed. They conclude that the increased use of tobacco among young women in the past two to three decades is responsible for this dramatic change.

Primary muscular hydatid cyst causing arterial insufficiency: case report and literature review

Hydatid disease, though known to occur in most organs and areas of the body, is extremely rare in skeletal muscle. In this article the authors present a case of a primary muscular hydatid cyst, originating from the adductor muscle group, causing obstruction of the femoral artery and vein.
