Effects of age of onset on disease characteristics in non‐segmental vitiligo

In patients with vitiligo, the clinical and laboratory features of the disease may vary according to time of onset. This is addressed in the literature by only a few studies with conflicting results. The aim of this study was to determine the demographic and clinical features of patients with non‐segmental vitiligo and to establish the association between vitiligo and autoimmune diseases with a focus on time of disease onset. A total of 224 vitiligo patients for whom complete medical records were available were evaluated retrospectively. Demographic data, scores on the Vitiligo Area Score Index (VASI), clinical features, vitiligo disease activity, repigmentation status, presence of any accompanying autoimmune disease, antinuclear antibody (ANA) titers, serum levels of glucose, thyroid‐stimulating hormone (TSH), thyroxine (T4) hormone, anti‐thyroid peroxidase (anti‐TPO), and anti‐thyroglobulin (anti‐TG) were recorded. The prevalence of halo nevi was significantly higher (P < 0.001) among children than in other patient groups. The prevalence of leukotrichia was higher in adults with adult‐onset disease than in either pediatric patients or adults with childhood‐onset disease (P = 0.002). Both anti‐TG and anti‐TPO levels were significantly higher in adults with adult‐onset disease than in pediatric patients and adult patients with childhood‐onset disease. The prevalence of autoimmune disease was 22.2%. Anti‐TG levels were significantly higher in patients with treatment‐related repigmentation than in those without repigmentation. This study shows that clinical features and associations with autoimmune disease may vary according to the age of onset of vitiligo.     

Early and late diagnoses of 17β-Hydroxysteroid dehydrogenase type-3 deficiency in two unrelated patients

17β-hydroxysteroid dehydrogenase type 3 deficiency is a rare cause of 46 XY disorders of sexual development. Mutations in the HSD17B3 gene result in reduced activity of the 17β-HSD3 enzyme, decreasing the conversion of androstenedione to testosterone. In this report, two cases, admitted with different clinical findings in the neonatal and adolescent periods and were decided to be raised in different genders are presented. The first case who had complete female external genitalia presented on the third postnatal day with the complaint of swelling in the groin. He was decided to be raised as a male and was treated successfully with parenteral testosterone in order to increase phallus size before surgical correction of the external genitalia. The second case was an adolescent girl who presented due to pubertal virilisation and primary amenorrhoea and chose female gender. Molecular genetic analyses of the HSD17B3 gene revealed two different previously reported homozygous variants. We emphasise that patients with 17β-hydroxysteroid dehydrogenase type 3 deficiency can present with heterogeneous clinical findings in different age groups. Early diagnosis is important to prevent future gender confusion and related problems.     

Trifid mandibular condyle: A case report

A few cases of bifid, but no case of trifid mandibular condyle, have been reported in the literature. This article presents the first reported case of trifid mandibular condyle in a living subject with a history of previous trauma to the temporomandibular joint (TMJ). Additionally, the patient's other condyle was bifid. The patient had no complaint related to the functions of TMJ except for minimal weakness following chewing. The etiology and the prognosis of bifid and trifid condyle are discussed briefly. We considered computed tomography essential to rule out early stages of TMJ pathology in similar cases that resemble trifid mandibular condyle on conventional radiographs.     

Spontaneous bladder rupture due to chronic cystitis 20 years after cystolithotomy

Spontaneous bladder rupture is a very rare condition. The majority of the cases are due to long-term indwelling catheters, radiation, or acute infravesical obstruction. Spontaneous rupture of the bladder due to inflammation is extremely rare. A case of intraperitoneal bladder rupture due to chronic cystitis is reported. Exploratory laparotomy and partial cystectomy were performed. Diagnosis and treatment are discussed.     

Natural course and predicting self-reported improvement in patients with chronic fatigue syndrome with a relatively short illness duration

OBJECTIVE: To describe the course of fatigue in chronic fatigue syndrome (CFS) patients with a relatively short duration of complaints and to test which psychosocial factors predict spontaneous improvement 1 year later. METHODS: Seventy-nine patients with a complaint duration of less than 2 years were tested at baseline and 78 of the same group at 1-year follow-up. During this time period, no systematic intervention took place. Self-reported improvement and fatigue severity were the main outcome measures. RESULTS: Forty-six percent (95% confidence intervals, 95CI = 35-58%) of the patients with a short illness duration reported to be improved. This was a significantly (chi(2) = 20.3, P < .001) higher percentage compared to the 20% (95CI = 15-26%) self-reported improvement in a previously published natural-course study among 246 CFS patients with a longer illness duration. Persistence of complaints after 1-year follow-up was associated with high baseline levels of experienced concentration problems, less strong psychosocial causal explanations for the complaints, and higher levels of the experienced lack of social support. Baseline fatigue severity predicted fatigue severity at follow-up. CONCLUSION: The results showed that CFS patients with a relatively short duration of complaints had a more favourable outcome compared to patients with a long illness duration. The data also indicated that complete recovery only occurred in patients with a complaint duration of less than 15 months. This finding has important implications, since it suggests that after such a time period spontaneous recovery hardly occurs.     

Oxidative stress in infants born to preeclamptic mothers

BACKGROUND: Oxidative stress may play an important role in the pathophysiology of preeclampsia. An increase in lipid peroxidation products and a decrease in antioxidant activity in preeclamptic women have been reported in many papers. The objective of this study was to evaluate oxidative stress in infants born to preeclamptic mothers. METHODS: Malondialdehyde (MDA) and glutathione (GSH) levels and glutathione peroxidase (GPx) and superoxide dismutase (SOD) activities were measured in cord plasma of infants born to preeclamptic (n = 18) or normotensive (n = 9) mothers. RESULTS: Gestational age was similar in both groups. The mean birth weight was significantly lower in the preeclamptic group (P = 0.007). Maternal age, primigravidity, antenatal steroid use, premature rupture of the membranes, clinical chorioamnionitis and adverse neonatal outcomes including sepsis, respiratory distress syndrome and neonatal mortality did not differ between groups. Cesarean delivery was significantly higher in the preeclamptic group. There was no significant difference in cord plasma levels of MDA and GSH, and activity of GPx between the preeclamptic and control groups. SOD was found to be increased in preeclamptic group (P = 0.03). CONCLUSIONS: We concluded that although cord plasma MDA levels were similar in both the preeclamptic and control groups, increased SOD activity might be an indicator of increased oxidative stress in infants born to preeclamptic mothers.     

The effects of the incision types in myringoplasty operations on cosmesis

There is no study based on objective measurements about the cosmetic results of myringoplasty operation in medical literature. This study aims to show the differences in the auriculomastoid angle between the operations which were done with postauricular and endaural incisions. The auriculomastoid angle of 20 patients having had postauricular myringoplasty operation were measured both preoperative and postoperative periods. The auriculomastoid angles of 17 patients having had endaural myringoplasty operation were also measured in both preoperative and postoperative periods. Also, the patients were asked whether there was a change in the shape of their ears. It was observed that the increase of the auriculomastoid angles of the patients who had myringoplasty by postauricular incision was statistically significant when compared to the ones having had the operation by endaural incision. Also, the patients who had myringoplasty operation by postauricular incision realized the change in their ears significantly when compared to the other group. In this study, esthetically better results were observed in the myringoplasty operations done by endaural incision than the ones done by postauricular incision. When deciding on the incision type, this should be considered.
