THE OCCURRENCE OF SUBACUTE THYROIDITIS AFTER THE AMELIORATION OF HYPERCORTISOLISM FOLLOWING TRANSSPHENOIDAL SURGERY IN CUSHING'S DISEASE.

Only a few subacute thyroiditis (SAT) cases secondary to hypocortisolemia developed after successfully treating Cushing's disease (CD) have been reported. In this report, we present an SAT case, which developed immediately after discontinuation of steroid treatment for hypocortisolemia after the successful treatment of CD. A 54-year-old female patient who had recently been diagnosed with type 2 diabetes mellitus was admitted to our center with complaints of proximal myopathy and obesity. Serum cortisol did not suppress adequately after the 1 mg dexamethasone suppression test. Pituitary MRI of the patient with increased basal plasma ACTH level revealed a 6 x 5 mm right-sided adenoma. After successful surgical treatment, the patient was given ten months of steroid therapy due to a suppressed corticotroph axis. Shortly after the steroid treatment was discontinued, the patient was admitted with neck pain, fever, and thyrotoxicosis. The patient was diagnosed with SAT, and methylprednisolone treatment was started again. The underlying pathophysiological mechanisms in SAT cases that develop after the treatment of CD can only be speculated. One possible mechanism could be that the glucocorticoid deficiency develops after effective treatment of hypercortisolism alters the immunological responses or generates self-reactive cells and prepares an appropriate environment for the thyrolytic process.

The importance of hypophosphatemia in the clinical management of primary hyperparathyroidism.

AIM: The levels of serum phosphorus (P) are low or low-normal in primary hyperparathyroidism (PHPT), and there is an inverse relationship between the levels of parathormone (PTH) and P. However, when considering the diagnostic and surgical indication criteria of PHPT, serum P levels are generally ignored. The aim of this study was to retrospectively evaluate the association of serum P levels with the clinical outcomes of PHPT. MATERIALS AND METHODS: A retrospective evaluation was made of the data of 424 consecutive patients (370 females, 54 males) with PHPT who presented at our centre. RESULTS: The mean age of the study population was 57 ± 11.68 years. The mean P was 2.57 ± 0.53 mg/dl. Asymptomatic disease was determined in 199 (47%) patients. Male patients had significantly lower levels of P. Symptomatic patients and patients with renal stones, vitamin D < 20 µg/l, calcium level ≥ 11.2 mg/dl, 24 h urinary calcium > 400 mg/day, or hypomagnesemia, were seen to have significantly lower levels of P (p < 0.05). Hypophosphatemia (hypoP) was found in 202 of 424 patients (47%), and these patients had a higher rate of symptomatic disease (63% to 44%, p < .0001). Of the 61 (88%) patients with moderate hypoP, 54 (88%) had at least one of the surgical criteria. A statistically significant increase in the incidence of hypoP was determined in symptomatic and male patients. In the patients with hypoP, serum PTH and urine calcium levels were found to be higher, and lumbar T-scores and serum vitamin D levels were lower. The patients with hypoP had higher rates of renal stones and osteoporosis (p < 0.05). CONCLUSIONS: The current study results show that hypoP is associated with a higher risk of osteoporosis and renal stones in PHPT patients. Even if patients are asymptomatic, moderate hypoP may be associated with poor outcomes of PHPT. Therefore, moderate hypoP may be a new criterion for parathyroidectomy, regardless of hypercalcemia level.

Atherogenic index of plasma may be strong predictor of subclinical atherosclerosis in patients with Behçet disease.

OBJECTIVES: Behcet's disease (BD) is a systemic vasculitis characterized by cardiovascular complications. Early diagnosis of these complications can reduce morbidity and mortality. Carotid artery intima-media thickness (cIMT) and the logarithmic value of triglyceride to high density lipoprotein ratio (atherogenic index of plasma, AIP) are good markers of atherosclerosis. The purpose of this study was to investigate whether AIP is a predictive marker of subclinical atherosclerosis in BD patients. PATIENTS AND METHODS: A total of 84 BD patients (60 male, 24 female) and 84 healthy control individuals (58 male, 26 female) were included in this study. cIMT measurements were made, and AIP values were calculated. RESULTS: cIMT (p < 0.001) and AIP (p < 0.001) values of the BD patients were higher than those of the control group. A strong independent relationship was found between the AIP value and cIMT (ß = 0.232, p = 0.018). In the subgroup analysis, the cIMT and AIP values of male BD patients were higher than those of female BD patients. CONCLUSION: Increased AIP and cIMT values can be a good marker for subclinical atherosclerosis in BD patients, especially in male BD patients.

Prevalence of abnormal oral cytology and impact of sexual behavior in women with abnormal cervical cytology.

UNLABELLED: PURPOSE OFINVESTIGATION: To assess the frequency of oral cytological abnormalities in women who have cervical intraepithelial lesions, and transmission of infection depending on their sexual behavior. The authors also aimed to investigate the oral cytological changes in male partners. MATERIAL AND METHODS: Thirty patients with abnormal cervical cytological results via punch biopsy formed the case group, and 68 patients constituted the control group with normal cervical smear results. The Bethesda system was used for classification of the cytological alterations. RESULTS: Oral dysplasia was significantly higher in the squamous intraepithelial lesion (SIL) group. Oral sex percentage was 43.3% in SIL group, whereas it was 19.1% in the control group. History of genital warts in women with SIL was also significantly higher in the case group. Three patients were diagnosed with abnormal oral cytology in the SIL group (10%), however abnormal oral cytology was not detected in the control group. No oral dysplastic changes was identified in the male partners of women with oral lesions. CONCLUSION: The authors detected oral dysplastic changes in the SIL group, especially in the (low grade squamous intraepithelial lesion (LGSIL) patients. Interestingly they could not find any oral dysplastic changes in the male partners of the study population.

Effect of sildenafil citrate on secondary healing in full thickness skin defects in experiment.

OBJECTIVES: An acceleration of the wound healing process expedites chronic wound patient's return to normal social environments significantly. Sildenafil, a cyclic guanosine monophosphate (cGMP)-dependent phosphodiesterase- 5 inhibitor has been shown to be a potent stimulator of angiogenesis through upregulation of cGMP. In our study, sildenafil was administered orally as a cost-effective supplement in the treatment of full thickness defects and chronic wounds in that manner with low incidence of side effects and morbidity. MATERIALS AND METHODS: Randomly selected 72 Wistar-Albino rats were divided into the two groups, 36 rats in each group. Control group (n =36) was divided further into a secondary healing group consisting of 9 rats and a pathology group consisting of 27 rats (pathology group 1: 9 rats, 4th and 7th day of wound healing, pathology group 2: 9 rats, 10th and 14th day of wound healing, pathology group 3: 9 rats, 21st and 28th day of wound healing. Experimental group consisted of 36 rats which received sildenafil citrate (Viagra® Pfizer, Germany) for secondary wound healing to proceed. RESULTS: The average wound healing period in the control group was 17.89 days and in the sildenafil citrate administered group 14.56 days. The difference of the epithelialisation on full thickness defects were more prominent on days 5 and 11 postoperatively. In the sildenafil citrate applied group, on the 7th day, the defect was 25% smaller and on the 13th day, the defect contracted by 38%. CONCLUSION: In conclusion, we believe that sildenafil citrate administered orally is a cost- effective supplement in the treatment of full thickness defects and chronic wounds in that manner with low incidence of side effects and morbidity (Tab. 4, Fig. 7, Ref. 34).

Combined triggering at the wrist and fingers and severe carpal tunnel syndrome caused by macrodystrophia lipomatosa. Case report and review of literature.

Macrodystrophia lipomatosa (MDL) is a rare, congenital, developmental anomaly causing localized overgrowth of a digit(s) or extremity. Trigger wrist is a relatively rare entity, which may be caused by a mass originating from a tendon, an anomalous muscle or intracarpal pathologies. A 42-year-old male patient presented with triggering during active motion of the fingers and intractable pain and numbness in fingers to our emergency department. He had hypertrophy of the entire right upper extremity and his huge thumb was amputated due to MDL four years ago. The index finger was bigger than the other fingers and thenar eminence area of the hand looked like a large mass. Resection of hypertrophic carpal bone and debulking of large soft tissue mass removed the carpal tunnel symptoms and limited the range of motion of the wrist and fingers. This is a case report of triggering at the wrist and severe carpal tunnel syndrome due to carpal bone enlargement and lipofibromatous hamartoma (LH) of the median nerve in a patient with MDL.

Occipital involvement in female pattern hair loss: histopathological evidences.

BACKGROUND: Female pattern hair loss (FPHL) is characterized by diffuse thinning of hair in the frontal and parietal areas of the scalp, and preservation of the frontal hairline is the norm. Hair on the occipital scalp is thought to be preserved. OBJECTIVE: To investigate whether the occipital area is involved in FPHL or whether there is a diffuse type of FPHL. METHODS: Forty female patients who had complained about hair loss for more than a year and were diagnosed with FPHL according to the Ludwig classification were included. Two punch biopsies from both the midscalp and the occiput were taken. Histological sections were prepared horizontally and stained with haematoxylin and eosin. Terminal follicles, vellus like follicles, anagen, telogen, catagen follicles, hair bulbs and telogen germinal units were counted in two sections of the upper dermis and the dermal-subcutaneous junction. If the terminal/vellus ratio was lower than 4:1, the diagnosis of androgenetic alopecia (AGA) was made. When the ratio was between four and seven to one, AGA was suspected. RESULTS: While 29 of 40 patients (72.5%) had findings consistent with AGA on the midscalp, 11 of 40 (27.5%) displayed signs of suspected AGA. Ten of 40 patients (25%) had AGA involving the occiput. CONCLUSION: The involvement of the occipital scalp is significant in FPHL. In some patients, this situation may be so apparent that clinically visible alopecia is seen. However, in other patients, it may also present only as thinning.

Narrowband UVB phototherapy for early-stage mycosis fungoides: evaluation of clinical and histopathological changes.

BACKGROUND: Early-stage (IA, IB, IIA) mycosis fungoides (MF) has long been treated with various agents including topical potent steroids, nitrogen mustard, carmustine, oral psoralen plus UVA (PUVA), broadband UVB, electron-beam radiotherapy, interferon-alpha and retinoids. However, each of these modalities is associated with various side-effects. Narrowband UVB (NB-UVB) therapy has the same effect but is safer to use than the other methods. OBJECTIVE: Our purpose in this prospective study was to determine the effects of NB-UVB in early-stage MF both clinically and histopathologically. MATERIALS AND METHODS: Twenty-three patients (20 men, three women, aged 27-78 years) with clinically and histologically confirmed MF were enrolled. Patients received NB-UVB therapy three times a week. Clinical and histological responses, cumulative doses, total number of treatments, side-effects and duration of remission period were noted. RESULTS: Six patients had stage IA MF, 15 patients stage IB and two patients stage IIA. Eighteen patients had patch stage and five patients had plaque stage histopathologically. All of the patients in the patch group had a complete response (CR). In the plaque group, three patients (60%) had a CR and two (40%) had partial (PR) or no clinical response (NR). The clinical response between patch and plaque groups was statistically significant. Regarding the histopathological findings, 17 (94.4%) had complete clearing and only one (5.6%) patient had a partial improvement in the patch group. In the plaque group, one (20%) patient had complete clearing and four (80%) patients had partial or no improvement. The difference between the two groups was statistically significant. In the patch group, the mean cumulative dose was 90.15 J/cm(2) and the mean number of treatments was 35.33. In the plaque group, the mean cumulative dose was 90.67 J/cm(2) and the mean total number of treatments was 39.40. The differences were not statistically significant, either between the mean cumulative dose or the mean number of treatments. The mean duration of follow-up was 10.87 months (range 1-25 months). Only one of the patients had a relapse. CONCLUSIONS: NB-UVB therapy for patients with early-stage MF is an effective and safe treatment with the effect lasting for months. We suggest that clinical clearance correlates with histological improvement except for patients in the plaque stage.

Prevention of adhesion to prosthetic mesh in incisional ventral hernias: comparison of different barriers in an experimental model.

BACKGROUND: The purpose of this study was to compare the intra-abdominal adhesion formation following ventral hernia repair by using oxidized regenerated cellulose (ORC) as a barrier underneath polypropylene mesh (PPM), and sodium hyaluronate/carboxymethylcellulose (HA/CMC)-coated PPM. METHODS: A ventral abdominal defect was created in each of 30 male rats which were divided into three groups. In group 1 (control) the defect was repaired with PPM; in group 2 ORC was laid over the viscera and the defect was repaired with PPM, and in group 3 HA/CMC-coated PPM was used for the repairing procedure. On the 28th postoperative day all the rats were sacrificed and adhesions were evaluated by laparoscopic exploration followed by histopathological examination. RESULTS: Animals treated with ORC and PPM, and HA/CMC-coated PPM showed significantly less adhesions than the control group (p = 0.026) and the intra-abdominal adhesions of the rats in these two groups were significantly easier to release than in the control group (p = 0.001). There was no significant difference between the ORC and HA/CMC groups. CONCLUSIONS: ORC used together with PPM is as effective as HA/CMC-coated PPM and ORC can be used as an adhesion barrier in intra-abdominal hernia repair.

Kaposi sarcoma associated with lipoedema.

Lipoedema is a form of lipodistrophy, which consists of abnormal accumulation of fat in subcutaneous tissue of the lower limbs. It does not cause any disease and it has not been reported association with malignity. We describe a 63-year-old woman occurring of Kaposi sarcoma on the lipoedema base.

Juvenile colloid milium: a case report.

Juvenile colloid milium is extremely rare, has its onset before puberty, may be inherited, may be caused by ultraviolet light, and is thought to result from the degeneration of keratinocytes. We report a 7-year-old girl with juvenile colloid milium. To the best of our knowledge this is the first reported case in Turkey.

Protracted febrile myalgia of familial Mediterranean fever.

Protracted febrile myalgia (PFM) includes severe myalgia of the upper and lower extermities accompanied by fever lasting up to 6 weeks, an elevated erythrocyte sedimentation rate and leucucytosis. We report a 13-year-old girl with PFM, and discuss the magnetic resonance imaging findings of the involved calf muscles. To our knowledge these are the only images of the pathology in the literature.

The effect of the genitofemoral nerve division on the contralateral descended testis in the unilateral cryptorchidism model.

It is widely accepted that there are degenerative changes and decreased spermatogenesis in the contralateral descended testis (CDT) in unilateral undescended testis (UUDT). While some investigators have postulated that the mechanism may be related to primary (congenital) or secondary (autoimmune, vascular, and neural) events, the exact mechanism of the damage to the CDT is still unknown. The present study was planned to investigate the role of the genitofemoral nerve (GFN) on the changes in the CDT. Forty male Wistar albino rats were divided into four groups of 10 each. During the newborn period a UUDT model was created and at the age of 30 days ipsilateral GFN division was done (group A). In addition, UUDT with intact GFN (group B), divided right GFN with bilateral scrotal testes (group C), and control (group D) groups were formed. When the animals reached early adulthood, they were killed and the testes were removed. Mean seminiferous-tubular diameter (STD) and germinal-ephitelium maturity was determined using modified Johnson testicular biopsy scores (TBS). The mean STD and TBS of the study groups did not show any differences suggesting that ipsilateral division of the GFN has no effect on the CDT in the UUDT model.
