The changes in the hair cycle during gestation and the post-partum period.

Background: In pregnancy, increased numbers of hair follicles remain in the anagen phase for longer periods due to hormonal changes and return to the telogen phase within 3-6 months of delivery with a sudden drop in hormone levels. This results in excessive shedding of hair known as post-partum telogen effluvium.

Objective: To determine the changes in the hair cycle during gestation and the post-partum period.

"Turkey ear" as a cutaneous maniestation of tuberculosis.

Lupus vulgaris is the most common morphological variant of cutaneous tuberculosis. Classical lupus lesions are often seen in the head and neck region. Turkey ear is a clinically descriptive term, previously being used for the earlobe with reddish indurated plaque lesions, which recently can be a sign for lupus vulgaris.

Clinicopathological consistency in skin disorders: a retrospective study of 3949 pathological reports.

Background: Although the clinicopathological approach plays an important role in skin disorder diagnoses, few studies have evaluated the consistency between clinical and histopathological diagnoses of skin disorders.

Objective: We sought to investigate the consistency, and factors affecting consistency, between clinical diagnoses and pathological diagnoses in patients with skin disorders referred for biopsy by dermatologists.

Methods: We retrospectively examined 3949 pathological reports of biopsy specimens, between 1999 and 2008.

Videodermoscopic pattern analysis of acral melanocytic nevi.

Three major and three minor types of acral melanocytic lesions have been described: parallel furrow, lattice-like, fibrillar, reticular, homogeneous and globular. To examine the dermoscopic patterns of acral melanocytic lesions and to investigate the association of these patterns with clinical features. This study included 419 acral melanocytic lesions of 295 patients.

The investigation of insulin resistance and metabolic syndrome in male patients with early-onset androgenetic alopecia.

Epidemiological studies have shown that diseases associated with insulin resistance and coronary artery disease are more frequently observed in men with androgenetic alopecia (AGA). We aimed to identify the presence of insulin resistance and metabolic syndrome in male patients with early-onset AGA. Fifty male patients (18-30 years) with AGA stage ≥ 3 (Hamilton-Norwood scale), body mass index < 27 and 40 weight- and age-matched male subjects were the study population.

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.

Lupus vulgaris of the popliteal fossa: a delayed diagnosis.

Lupus vulgaris (LV) is the most common form of cutaneous tuberculosis. It commonly presents on the head and neck regions. The diagnosis may be difficult when LV occurs at unexpected regions or in unusual clinical forms.

Subcutaneous cryptococcosis due to Cryptococcus diffluens in a patient with sporotrichoid lesions case report, features of the case isolate and in vitro antifungal susceptibilities.

Environmental fungi, in particular primary pathogens and Cryptococcus spp. can be responsible for skin lesions mimicking sporotrichosis. In this paper, we report a case of subcutaneous cryptococcosis in an apparently healthy, young male patient due to a non-C.

The presence of insulin resistance and comparison of various insulin sensivity indices in women with androgenetic alopecia.

We aimed to identify the association of female androgenetic alopecia with insulin resistance and to evaluate various simple insulin sensitivity indices and beta cell function in women with androgenetic alopecia (AGA). A cross-sectional study was performed in 66 non-obese women (24-44 years old), 41 with AGA alone and 25 healthy individuals. Blood glucose, insulin, c-peptide levels, oral glucose tolerance test (OGTT); insulin sensitivity and beta cell function indices derived from a single blood sample and OGTT were determined and compared in the two groups.

Phototrichogram findings in women with androgenetic alopecia.

Background/purpose: Androgenetic alopecia (AGA) in women is characterized by diffuse thinning in the frontal and parietal areas of the scalp; preservation of the frontal hairline is norm. Hair over the occipital scalp is preserved. The purpose of this work was to investigate the findings of phototrichogram (PTG) of the affected and the spared areas in women with AGA and to compare them with those of healthy subjects.

Comparison of various insulin sensitivity indices in psoriatic patients and their relationship with type of psoriasis.

Aim: We aimed to identify insulin resistance and its possible association with types, duration and severity of psoriasis, and to evaluate various simple insulin-sensitivity indices and beta-cell function in psoriasis.

Methods: A cross-sectional study was performed in 110 non-obese adults (18-50 years old): 70 with psoriasis (53 type I, 17 type II psoriasis) and 40 healthy individuals. Blood glucose, insulin and C-peptide levels were measured.

Prurigo pigmentosa treated with doxycycline.

Prurigo pigmentosa is characterized by an inflammatory phase with pruritic erythematous papules and a resolution phase with reticulated pigmentation. It is not a well known entity except in Japan. We present a Turkish young man with prurigo pigmentosa treated with doxycycline.

Sildenafil citrate-aided radiotherapy for the treatment of Kaposi's sarcoma of the penis.

We report a case of classical Kaposi's sarcoma involving multiple sites of the penis in a 62-year-old male who was treated with sildenafil citrate-aided electron beam therapy, resulting in complete resolution of the lesions.

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.
